[0001] This invention relates to an apparatus for treating a product, as e.g. known from
document
EP 1 378 322.
[0002] In particular, the apparatus is designed to carry out a surface treatment on a product,
and it is preferably designed to polish or tumble a surface of the product.
Background Art
[0003] There are prior art apparatuses for tumbling products, or similar surface treatments
on a product, in which a plurality of products is inserted in a container, together
with a treatment, or abrasive composition, with the tumbling barrel driven to vibrate
so as to move the products and the composition relative to each other, thus obtaining
a corresponding product surface treatment.
[0004] In some tumbling barrel models there are brackets or supports for mechanically anchoring
products, which are inserted in the tumbling container.
[0005] However, such apparatuses have setup times that are too long and limited versatility
in terms of use. The anchoring brackets allow the bracketing of very specific types
of products, which must be placed in very specific positions in the tumbling tank.
Disclosure of the Invention
[0006] This invention proposes a novel solution, alternative to the solutions known up to
now, and aims to overcome one or more of the above-mentioned disadvantages and/or
problems, and/or to meet one or more of the needs mentioned or inferable from the
above.
[0007] Therefore, an apparatus for treating a product according to claim 1 is provided.
[0008] In this way, it is possible to carry out a product surface treatment in a way that
is particularly rapid and easy for personnel, also with maximum operating flexibility.
[0009] In particular, the preparation of special magnetic anchoring means makes the apparatus
setup stage particularly easy and rapid, before a subsequent surface treatment operation.
[0010] Moreover, this means that, during processing, the products to be treated do not make
contact with each other, thus avoiding any possible risk of damage to them.

Detailed Description of the Preferred Embodiments of the Invention
[0012] The accompanying drawings from 1 to 3 illustrate a first preferred embodiment 10
of an apparatus for treating a respective product or part 11, in particular for polishing
a surface "S" of the product.
[0013] In particular, the apparatus is suitable for treating a product 11 comprising an
outer surface S to be polished, or to be subjected to tumbling, or barrel polishing.
[0014] To carry out the surface treatment, the apparatus uses a product treatment composition
13, designed to have an abrasive action on the product surface and, if necessary,
designed to have a detergent action on said product surface.
[0015] To obtain product treatment by the treatment composition or treatment means 13, the
apparatus comprises means designed to make the product treatment means 13 move relative
to the product 11.
[0016] Said means designed to make the product treatment means 13 move relative to the product
11, are in the form of means designed to make the product treatment means 13 vibrate,
in particular in such a way as to generate a vibrating movement of the abrasive composition
relative to the surface S to be treated, in that way obtaining a product 11 surface
treatment.
[0017] This apparatus comprises the use of product retaining means.
[0018] Advantageously, the product retaining means are in the form of magnetic anchoring
means.
[0019] The anchoring means, in particular magnetic, are designed to retain the product 11
on the product supporting means 12, in particular holding the product stationary relative
to the supporting means 12.
[0020] In practice, this apparatus comprises product supporting means, which are in the
form of a respective plate 12 forming a supporting and resting surface for the respective
product or part.
[0021] The plate 12 comprises an upper surface, relative to which, in particular, there
extend upwards means, or a peripheral wall 14 defining the containment means or tank
for the product 11 and for the treatment mixture or means 13.
[0022] According to the first preferred embodiment, as becomes clearer in this description,
the supporting plate 12 is also designed to transmit, in particular to the product
and/or to the treatment composition, the vibration suitable for guaranteeing the desired
treatment, that is to say, movement of the treatment composition relative to the surface
to be treated.
[0023] Advantageously, the supporting means 12 also form or comprise magnetic anchoring
means.
[0024] In particular, the magnetic anchoring means are in the form of means which can be
switched on and off. In particular they can be switched on to apply a retaining action,
especially while the treatment is carried out, and switched off to eliminate the retaining
action and allow removal of the products 11 from the apparatus and their substitution
with other products to be treated.
[0025] In practice, as Figure 3 clearly shows, the supporting plate or panel 12 comprises
a plurality of magnetic anchoring sections 12a, 12b, formed by respective anchoring
magnetic or magnetisable poles.
[0026] The magnetic anchoring panel, which may be made in the substantially known way and
therefore is not described in further detail, comprises a plurality of sections 12a,
12b having opposite polarity, that is to say "north", labelled 'N' in Figure 3, and
"south", labelled 'S'.
[0027] The magnetic anchoring poles 12a, 12b are of the type which can be switched on and
off, in particular electrically, especially by the effect of a corresponding electric
current passing through the turns of a corresponding electric winding, or coil, lying
in the respective pole. All of this being known to experts in the field and therefore
not illustrated and described in detail.
[0028] According to the embodiment illustrated, which must not however be considered exclusive
and limiting for this invention - other configurations being possible for these magnetic
means 12 - the magnetic anchoring poles 12a, 12b can be arranged in respective transversal
and longitudinal lines of the panel 12 and are such that the poles adjacent to each
other have opposite polarity and in any case produce a suitable retaining action on
the product and on the containment means.
[0029] In practice, according to the embodiment illustrated, in the longitudinal or transversal
directions of the panel 12, a pole 12a with respective magnetic polarity is adjacent
to poles 12b which have an opposite magnetic polarity.
[0030] Advantageously, to impart a vibration to the treatment means 13, the supporting means
12 are made to vibrate, therefore, they are in the form of vibrating means.
[0031] Therefore, advantageously, the supporting means, as well as being in the form of
vibrating means, are such that they also form magnetic anchoring means.
[0032] These vibrating supporting and anchoring means are in the form of a respective plate
12, forming the base of the containment tank or means 14, on which plate the product
is sustained, with an advantageous removable layer 121 interposed between them, designed
to form a protective layer for the plate 12, avoiding wear on the magnetic plate 12
caused by the abrasive material.
[0033] In particular, on the supporting plate 12, or on the base of the containment means
14, there is a removable layer 121, made of ferromagnetic material so as to allow
advantageous magnetic field flows and to be advantageously held on the plate 12.
[0034] Advantageously, the removable layer is made in the form of a metal sheet 121.
[0035] Moreover, the removable layer 121 may be hermetically positioned above the supporting
plate or the base of the containment means 14, preventing the treatment or abrasive
composition from making direct contact with the upper surface 12' of the supporting
plate 12.
[0036] In practice, as illustrated, the removable layer 121 is positioned above and in contact
with the upper surface 12' of the supporting plate 12 and within the peripheral wall
14, that is to say, within the containment means.
[0037] As can be inferred from Figures 1 and 2, there are therefore advantageous containment
means 14 for the product and/or the treatment composition or mixture 13.
[0038] The containment means 14 therefore comprise a respective base wall, formed by the
upper surface of the supporting panel 12, or by the superposed layer 121, and a respective
lateral peripheral containment wall 14.
[0039] According to this preferred embodiment, the containment means, in the form of a single
tank or container 14, and advantageously designed to contain a plurality of products
11, comprise an extension in plan view which substantially corresponds to the plan
view extension of the supporting plate 12 from whose lateral edge they extend upwards.
[0040] As illustrated, the containment means 14 comprise means 18 for draining the treatment
liquid.
[0041] The drainage means 18 comprise a tube 18', in communication with the inner chamber
14c of the containment means 14 and comprising opening/closing valve means, labelled
18", for draining the liquid.
[0042] As illustrated, the container 14 also comprises a large drainage outlet 41 for the
treatment composition, at the base of the treatment container or tank, opening into
a respective wall of the peripheral or lateral wall 14 of the container. The drainage
outlet 41 allows drainage of the composition from the container due to the movement,
in particular to the vibrating movement of the container or of the supporting plate
12, which moves the composition out through the outlet 41. As shown, the large outlet
41 comprises a corresponding door which can be opened and closed again 42.
[0043] As illustrated, there are also means 30 for vibration of the supporting means, said
vibration means in particular being in the form of a vibration motor which is preferably
fixed in position below the supporting plate 12.
[0044] In practice, the vibration means are in the form of a corresponding vibration motor
30 and are suitably connected, in particular fixed or anchored, to the supporting
plate 12.
[0045] In particular, the vibration means 30 are supported on the supporting plate 12 and
are, advantageously, positioned below the magnetic anchoring and supporting plate
12.
[0046] As shown in the accompanying drawings, the vibration motor 30 shaft preferably extends
horizontally, that is to say, parallel with the magnetic supporting surface 12.
[0047] The respective supporting plate 12 is connected to a base 120 of the apparatus, by
elastic means which allow its vibration relative to the base and which are preferably
in the form of springs, in particular helical springs extending vertically, the elastic
means sustaining the supporting plate 12 on the apparatus base 120 and being labelled
32 in Figure 1.
[0048] This apparatus also comprises, although not shown in detail in the accompanying drawings,
advantageous control means for the vibration means and the magnetic anchoring means
12a, 12b. The control means are in the form of electronic processing means, for example
a PC or a PLC.
[0049] Advantageously, the control means are suitably connected, in particular by electric
connections, to the vibration motors 30 and to the magnetic poles 12a, 12b, and, to
begin the treatment, they are designed to switch on the vibration means 30 only after
the magnetic anchoring means have been switched on.
[0050] Vice versa, at the end of the treatment, the control means are designed to switch
off the magnetic anchoring means, to allow removal of the products 11, only after
the vibration means 30 have been switched off.
[0051] The treatment composition can move in contact with the surface to be cleaned due
to the vibrations imparted to the composition 13 through the respective supporting
panel 12, and, if necessary, through the containment means 14.
[0052] In practice, the treatment composition 13 is kept moving relative to the product
to be treated by a vibrating movement.
[0053] As illustrated, the container 14 designed to contain a plurality of products 11 to
be polished, has a general quadrangular shape. In particular, as shown, it is square
in plan view.
[0054] As illustrated, the lateral walls 14 forming the containment means or tank are fixed
to the supporting plate 12, to which they are fixed by screws V.
[0055] As shown in Figure 1, there are also advantageously product sustaining means 125
comprising means which can be anchored to the apparatus by magnetic attraction.
[0056] In this way, this apparatus can also be used to treat products, for example made
of aluminium, plastic or other material, which are not ferromagnetic, that is to say,
which are not themselves sensitive to magnetic attraction.
[0057] In particular, the auxiliary means for directly sustaining the product are in the
form of a body or base unit 125 made of ferromagnetic material, as illustrated, or,
according to another embodiment not illustrated, simply having a layer or portion
made of ferromagnetic material.
[0058] As illustrated, the sustaining base unit or body 125 is in the form of a block of
material with predetermined thickness and comprising a lower surface 125a for resting
on the supporting means, in particular as illustrated, for resting on the base of
the container. The sustaining body 125 also comprises a surface 125b on which to rest
a corresponding surface 11b of the product to be treated 11.
[0059] Moreover, the sustaining means 125 comprise means for securing the product to the
supporting means, which, according to a preferred embodiment, are, in particular,
formed by means which are inserted in a corresponding part, or hole, in the product
11.
[0060] In practice, screw means 126 are provided, which are inserted in a corresponding
hole 125c in the sustaining body 125 and in a further hole 11a made in the product
11, that is to say, a hole which opens in a corresponding face of the product 11 for
engaging with the sustaining body 125.
[0061] Figures 4 and 5 show a second preferred embodiment of the apparatus 10 for treating
a product 11, having components similar to those of the previous embodiment, labelled
with the same reference characters, and which are not described again in detail to
avoid making this description too long.
[0062] The second preferred embodiment is also suitable for treating a product 11 comprising
a surface S to be polished or to be subjected to tumbling, or barrel polishing.
[0063] In this second preferred embodiment, the containment means comprise containment means
or containers 140 designed to contain a single product. These containers for a single
produce comprise, in particular, a base 140a whose plan view extension is such that
it contains and supports a single product 11. In practice, the width or plan view
extension of the container 140 is such that it is slightly greater than the outer
perimeter of the product 11.
[0064] That setup of individual containment means or containers 140 for each product 11
allows savings in terms of the quantity of treatment composition 13.
[0065] The containment means 140 are preferably made of ferromagnetic material, or, like
those of the first preferred invention, of metal, with the product 11 also being made
of ferromagnetic material or supported on a base unit 125 made of ferromagnetic material,
as illustrated for the first preferred embodiment.
[0066] In practice, the containment means 140 are also subject to the magnetic anchoring
action, that is to say, they are magnetically anchored to the supporting means 12.
[0067] In this way, it is possible to position the containers at the most suitable points
of the supporting panel 12 or within the containment means 14.
[0068] It also guarantees easy, simple product treatment, without compromising the automatic
retaining action.
[0069] These containment means 140 can be removed from the supporting means 12, for substitution,
maintenance or simple washing, or for setting up the apparatus 10 for operation as
illustrated relative to the first preferred embodiment.
[0070] As illustrated, the containment means 140 comprise a base wall 140a, which rests
on the plate 12, in particular on the upper surface 12' of the plate 12 and on which
the product 11 or the base unit 125 supporting a respective non-ferromagnetic product
11 rests.
[0071] As illustrated, the containment means 140 also comprise a lateral peripheral containment
wall 140b, extending from the base wall 140a.
[0072] The containment bodies 140 are preferably made in the form of a tubular body, in
particular with a circular cross-section, made of suitable ferromagnetic material,
comprising a base 140a, and open at the upper end, and directly fixed, by magnetic
attraction to the vibrating supporting panel 12.
[0073] In this way, a reduced quantity of treatment composition 13 can be used, basically
just what is needed to treat the surface of a respective product which is contained
in the individual containment body 140.
[0074] Once the treatment is complete, the magnetic attraction can be switched off, freeing
the containers 140, and the containers 140 can be lifted out of and removed from the
machine, allowing access to the products treated 11.
[0075] According to a third preferred embodiment illustrated in Figure 6, whose components
are similar to those of the previous embodiments and are labelled with the same reference
characters, and which are not described again in detail to avoid making this description
too long, there are auxiliary product sustaining means 125 which form, or comprise,
a respective holder 127, designed to receive or retain a corresponding part or end
of the product 111c.
[0076] As illustrated, a screw 126' engages with and locks the end 111c of the product in
the holder 127.
[0077] In particular, there is a respective inner holder 127, designed to receive or retain
a corresponding part or end of the product 111c.
[0078] This solution is particularly suitable for treating an item or product having a surface
which cannot have attachment holes in it for insertion of a corresponding fixing screw,
or if its resting surface is not large enough to allow its magnetic locking.
[0079] According to a fourth preferred embodiment 100 illustrated in Figure 7, whose components
are similar to those of the previous embodiments and are labelled with the same reference
characters, and which are not described again in detail to avoid making this description
too long, there is a magnetic anchoring plate 212, which can be positioned above and
fixed to the base 212' of a treatment tank or container 214.
[0080] Said plate 212 is like the plate 12 of the previous embodiments and, to avoid a description
which it too long, is not described in detail again.
[0081] As illustrated, the added magnetic plate 212 is shaped in such a way that it has
an outer peripheral edge 212a and an inner peripheral edge 212b forming a free central
space for insertion of the plate 212 on a corresponding central projection 213 of
the treatment tank 214.
[0082] There are advantageous means for switching the plate 212 magnetic action on and off,
which are connected to the magnetic anchoring plate 212 through a hole 212" made in
the base, or, in another embodiment not illustrated, in the lateral wall 214' of the
tank 214.
[0083] The panel 212 is fixed to the treatment tank 212 by means of corresponding screws
226 or fixing means for the panel or plate, in particular connecting to the base of
the tank or container 214.
[0084] This embodiment 100 can form an apparatus equivalent to the apparatus of the previous
embodiments, starting with prior art treatments machines, making minimal modifications
to them, such as the threaded holes for the plate 212 fixing screws 226 and if necessary
the hole 212" for the connecting cable C to the control means.
[0085] A fifth preferred embodiment 200 of the apparatus for treating a product is illustrated
in Figures 8 and 9. This fifth preferred embodiment is in the form of a tumbling apparatus
comprising a treatment tank or container 214 extending in a circular fashion. In this
fifth preferred embodiment the components similar to those of the previous embodiment
are labelled with the same character references and, to avoid making this description
too long, are not described again in detail.
[0086] This fifth preferred embodiment also comprises a magnetic surface 12 superposed by
a corresponding protective layer 121' which extends with a ring shape in plan view.
[0087] This fifth preferred embodiment comprises advantageous means 201 for closing the
container, in particular in the form of a lid which, when closed, rests on the upper
edge of the peripheral wall 214' of the container 214 and can conveniently be opened.
[0088] The closing means 201 prevent the material or treatment composition from coming out
of the treatment container.
[0089] In particular, as illustrated, the lid 201 is supported by the container and has
a lowered closed position and a raised open position.
[0090] In particular, as illustrated, the lid 201 is hinged at a lateral wall of the container,
at a point labelled 202 in Figure 9 and on the opposite side, or wall, has suitable
fastening means 203 for holding the lid 201 closed.
[0091] In this fifth embodiment, as illustrated, the vibration means or motor 30', as in
the fourth embodiment, have the respective shaft extending vertically, that is to
say, perpendicularly to the magnetic supporting surface 12.
[0092] In this fifth embodiment, as illustrated, the vibration means or motor 30' are in
the central housing 213 and are fixed, by screws 130, to the vibrating magnetic surface
12.
[0093] A sixth preferred embodiment of the apparatus for treating a product is illustrated
in Figure 10. In this sixth preferred embodiment the components are similar to those
of the previous embodiment and are labelled with the same character references and,
to avoid making this description too long, are not described again in detail.
[0094] As illustrated, in this sixth preferred embodiment the apparatus base 120 is suitable
for supporting at least a first and a second unit 10a, 10b for treating respective
products 11.
[0095] In practice, products already treated or to be treated can be loaded and unloaded
to and from a respective unit, for example the unit 10a, while the other unit 10b
is activated and operating for treating further products.
[0096] In fact, while one unit 10a is in the operating condition, personnel can advantageously
proceed with unloading and loading of the other unit 10b. Vice versa, when the unit
10b is in turn in its treatment phase for respective products 11, personnel can unload
products 11 from the other unit 10a and load further products 11 in that unit 10a.
[0097] As illustrated, this sixth apparatus also comprises advantageous control means 34
for the vibration means and the magnetic anchoring means 12a, 12b.
[0098] The control means 34 are in the form of electronic processing means, for example
a PC or a PLC.
[0099] Advantageously, the control means 34 are suitably connected, in particular by electric
connections 36, to the vibration motors 30 and to the magnetic poles 12a, 12b, and,
to begin the treatment, they are designed to switch on the vibration means 30 only
after the magnetic anchoring means have been switched on.
[0100] Vice versa, at the end of the treatment, the control means 34 are designed to switch
off the magnetic anchoring means, to allow removal of the products 11 and if necessary
also the containers, only after the vibration means 30 have been switched off.
[0101] This sixth preferred embodiment shows how the containment means for the treatment
composition 13 are formed by the product itself.
[0102] As shown in Figure 10, the product to be treated 11 comprises, in particular, an
inner cavity S formed by the surface to be polished and, in particular, being in the
form of a mould having a first and a second part which fit together at opposite surfaces
to form a dividing line.
[0103] In practice, the mould consists of a first part and a second part which are brought
close to each other and which, in use, receive the material to be moulded and are
then moved away from each other to allow the material or product to come out. In practice,
the first and second parts of the mould fit together to form a forming cavity S for
a corresponding product, in particular in the form of a container, such as a glass
bottle. However, it shall be understood that this apparatus is suitable for treating
any type of product, in particular also a mould for plastic bottles or containers
or a product of any other type having a corresponding inner cavity.
[0104] The product treatment composition is housed in the cavity to be treated S of the
product 11.
[0105] The treatment composition can therefore move in contact with the surface to be cleaned
due to the vibrations imparted to the composition 13 through the product 11 itself
and the respective supporting panel 12.
[0106] In practice, a vibrating movement keeps the treatment composition 13 moving relative
to the product to be treated 11.
[0107] As illustrated, the container 14 may be designed to contain a plurality of products
or moulds 11 to be polished, as is the case for the one supported on the panel 10b,
or it may contain a single product 11, as happens for those supported on the panel
10a.
[0108] In particular, as illustrated, in this sixth preferred embodiment, the product 11,
in the individual containers of the apparatus 10a, extends upwards beyond the upper
end of the peripheral wall of the respective containment means 140 and, also, upwards
beyond, or above, the upper level of the treatment agent 15 housed in the containment
means 140 and outside the mould 11.
[0109] The treatment agent 15 is in communication through the mould 11 with the treatment
composition 13, allowing the latter to be kept in the optimum condition, for example
to supply it with a desired quantity of water or other substance.
[0110] In that way, any dispersion of the abrasive composition outside the cavity to be
polished in which the composition is housed can be avoided.
[0111] From at least some of the above-mentioned preferred embodiments of the apparatus
it can be inferred that a supporting and/or magnetic plate or panel 12 is provided,
which is directly sustained or resting on elastic means, or springs, 32, 32 which
allow its respective movement, in particular the vibrating movement.
[0112] Therefore an apparatus is obtained whose structure is advantageously simplified,
with limited weight and low demands on the actuator means 30.
[0113] In particular, it is clear, from the above-mentioned preferred embodiments, that
the supporting and/or magnetic plate or panel 12 is positioned above the elastic sustaining
means, or springs, 32, 32, which allow its respective movement, in particular a vibrating
movement.
[0114] From at least some of the above-mentioned preferred embodiments of the apparatus,
it is also evident that the actuator, or vibration, means 30 are directly sustained
on the supporting and/or magnetic plate or panel 12.
[0115] In practice, the actuator means or motor, or the vibrations means, are sustained
on the elastic means, or springs, by means of the supporting and/or magnetic plate
or panel 12.
[0116] The supporting elastic means, or springs 32, have a respective axis of extension,
or of compression, which is perpendicular or substantially perpendicular to the main
plane of extension of the supporting and/or magnetic plate or panel 12, that is to
say, to the retaining surface of the latter, their axis preferably being vertical.
[0117] From at least some of the above-mentioned preferred embodiments of the apparatus,
it is also evident that the actuator or vibration means 30 hang from the supporting
and/or magnetic plate or panel 12.
[0118] From at least some of the above-mentioned preferred embodiments of the apparatus,
it is also evident that the actuator or vibration means 30 hang below the supporting
and/or magnetic plate or panel 12.
[0119] As may be inferred, the elastic resting means for the supporting and/or magnetic
plate or panel 12 comprise a plurality of elastic or spring elements 32 which are
peripherally distributed and preferably located close to or at the peripheral edge
of the supporting and/or magnetic plate or panel 12.
[0120] In practice, the supporting and/or magnetic plate or panel 12 comprises a lower surface,
in particular a flat, horizontal lower surface, which rests on the transversal upper
face of the respective elastic sustaining means 32.
[0121] As may be inferred, the actuator or vibration means 30 are positioned radially internally
relative to the elastic resting elements 32 for the supporting and/or magnetic plate
or panel 12.
[0122] Moreover, as may be inferred, the supporting and/or magnetic plate or panel 12 comprises
a direct or indirect resting surface for products or parts to be treated, having an
extension, particularly in plan view, such that it can support a plurality of parts,
which may be placed in any desired or suitable position on the resting surface of
the supporting panel 12.
[0123] Moreover, as may be inferred, the wall 14 forming the containment means or tank,
in particular the lateral wall of the latter, is connected in such a way that it can
engage with or disengage from the supporting and/or magnetic plate or panel 12.
[0124] In particular, the wall 14 forming the containment means or tank, in particular the
lateral wall of the latter, is connected by respective screws V, each inserted - in
particular from the bottom - in a hole V', preferably vertical, in the panel or frame
of the panel 12 and also inserted in a corresponding threaded hole V", also preferably
vertical, in the bottom, at the respective lower edge of the wall 14, extending around
the periphery and/or forming the tank lateral containment wall.
[0125] As illustrated, the fixing screw V comprises a threaded shank and a widened head
which engages with an annular shoulder of the insertion hole V'.
[0126] From at least some of the above-mentioned preferred embodiments of the apparatus,
it is also evident that the supporting and/or magnetic plate or panel 12 forms the
lower or base wall of the containment means or tank.
[0127] As may easily be inferred from Figure 3, the supporting and/or magnetic plate or
panel 12 has a load-bearing structure formed by a respective housing frame 12t, in
particular metal and ferromagnetic, forming respective means, or holders 12s for housing
magnetic anchoring means or poles which are connected, in particular in a fixed way,
to said frame.
[0128] Moreover, obviously, the actuator means or vibration means 30 are connected to the
load-bearing structure 12t of the supporting plate or panel.
[0129] Moreover, as can be clearly seen, the wall 14 forming the containment tank, in particular
forming the lateral wall of the latter, is connected to the load-bearing structure
12t of the supporting plate or panel 12.
[0130] Moreover, as can be clearly seen, the wall 14 forming the containment tank, in particular
forming the lateral wall of the latter, is connected to a lowered peripheral portion
of the load-bearing structure of the supporting plate or panel.
[0131] As may be inferred from the accompanying drawings, in at least some of the preferred
embodiments the supporting and/or magnetic plate or panel 12 comprises a peripheral
edge 112' designed to receive coaxially and externally the lower edge of the wall
14 forming the containment tank, in particular forming its lateral wall and in such
a way as to form centring means for it during insertion of the peripheral wall 14
on the supporting panel or plate 12.
[0132] Figures 11 and 12 show a seventh preferred embodiment of the apparatus 300 for treating
a respective product, or products 11, having various components similar to those of
the previous embodiments, labelled with the same reference characters, and which are
not described again in detail to avoid making this description too long.
[0133] Even this preferred embodiment is suitable for treating one or more products 11 comprising
a surface S to be polished or to be subjected to tumbling, or barrel polishing.
[0134] In this seventh preferred embodiment, the containment means comprise containment
means or containers 340 designed to contain a single product, or at the most a single
group of products, in particular, a limited number of products, and having a plan
view extension which is less than, in particular much less than, the plan view extension
of the supporting panel 12.
[0135] In particular, the panel is designed to support a plurality of individual containment
means, in particular spaced out.
[0136] These individual containment means therefore preferably have a plan view extension
such that they contain and support a single product 11 and a respective cross-section
which is preferably suitable for matching the outer profile or plan view shape of
the product to be treated.
[0137] In practice, the containment means of a single product or a single-product container
may have a circular shape in plan view, as shown in the embodiment labelled a, or
a (regular or irregular) polygonal plan view shape, in particular quadrangular, preferably
square, as shown in the embodiment labelled b, or rectangular, as shown in the embodiment
labelled c, or triangular, as shown in the embodiment labelled d.
[0138] Preferably, the width, or plan view extension of the respective container 340 is
such that it is slightly greater than the width or plan view extension of the respective
product 11.
[0139] That setup of individual containers or containment means 340 allows savings in terms
of the quantity of treatment composition 13.
[0140] These containment means 340 are made of ferromagnetic material, in particular metal,
with the product 11 also being made of ferromagnetic material or supported on a base
unit 125 made of ferromagnetic material.
[0141] In practice, the containment means 340 are also subject to the magnetic anchoring
action, that is to say, they are magnetically anchored to the supporting means 12.
[0142] In this way, it is possible to position the containers at the most suitable points
of the supporting panel 12 or within the containment means 14.
[0143] It also guarantees easy, simple product treatment, without limiting the retaining
action applied to the product.
[0144] These containment means 140 can be removed from the supporting means 12, for substitution,
maintenance or simple washing, or for setting up the apparatus 10 for different operation.
[0145] As illustrated, the containment means 340 comprise a lateral peripheral containment
wall 340b, extending axially and having a respective thickness.
[0146] These containment means 340 are open both at the bottom and at the top, that is to
say, at both axial ends of the container body.
[0147] In practice, these containment means 340 comprise a lower edge 340a for directly
resting on the supporting panel 12, in particular on its respective upper surface
or on the removable upper layer.
[0148] The respective containment body 340 is made in the form of a tubular body, in particular
with a circular or polygonal (i.e.: quadrangular or triangular, as indicated above)
cross-section, made of suitable ferromagnetic material, comprising an edge at the
upper end, and which directly rests on the vibrating supporting panel 12, and in particular
is retained in contact with the latter thanks to the magnetic attraction of the supporting
panel.
[0149] In practice, improved attraction of the individual product to be treated is achieved
thanks to the fact that it rests directly on the supporting panel 12.
[0150] Once the treatment is complete, the magnetic attraction can be switched off, freeing
the containers 340, and the containers 340 can be lifted out of and removed from the
machine, allowing access to the products treated 11.
[0151] The hold could also be improved by using an O-ring or hermetic seal means, in particular
made of elastic material, between the lower edge of the individual product or part
container and the supporting surface below. A respective recessed circular holder
could be provided at the lower edge of the container body 340 for housing the O-ring.
[0152] According to an eighth preferred embodiment illustrated in Figure 13, whose components
are similar to those of the previous embodiments and are labelled with the same reference
characters, and which are not described again in detail to avoid making this description
too long, auxiliary sustaining means 425 are provided for a plurality of products,
forming, or comprising, respective holders 427, designed to receive or, if necessary,
retain a corresponding part or end of the corresponding product 111c.
[0153] In particular, said holders on the common base unit 425 may be identical or different,
as illustrated in this preferred embodiment.
[0154] As may be inferred from Figure 13, advantageously said product sustaining means 425
are retained or anchored to the apparatus, that is to say, to the supporting panel
12, by magnetic attraction.
[0155] In this way, this apparatus can also be used to treat products, for example made
of aluminium, plastic or other material, which are not ferromagnetic, that is to say,
which are not themselves sensitive to magnetic attraction.
[0156] In particular, the auxiliary means for directly sustaining the product are in the
form of a body or base unit 425 made of ferromagnetic material, as illustrated, or,
according to another embodiment not illustrated, simply having a layer or portion
made of ferromagnetic material.
[0157] As illustrated, the sustaining base unit or body 425 is in the form of a block of
material with predetermined thickness and comprising a lower surface 425a for resting
on the supporting means, in particular as illustrated, for resting on the supporting
panel or plate 12. The sustaining body 425 also comprises an upper surface 425b, in
particular on which the respective product rests or relative to which a corresponding
retaining screw, or means, for the product extends, or into which there is recessed
a respective inner holder for housing a corresponding end of the product.
[0158] As illustrated, a first holder labelled "e" is designed to receive, resting on it,
the part or product to be retained by corresponding fixing means.
[0159] A second holder labelled "f" comprises means for fixing the product or part in a
raised position relative to the base unit 425.
[0160] Moreover, as illustrated, a third holder labelled "g" is in the form of a respective
inner or recessed holder 427, designed to receive or retain a corresponding part or
end of the product 111c. In particular, in this third embodiment of the holder "g"
a screw 426' engages with and locks the end 111c of the product in the holder 427.
[0161] This solution is particularly suitable for treating an item or product having a surface
which cannot have attachment holes in it for insertion of a corresponding fixing screw,
or if its resting surface is not large enough to allow its magnetic locking.
[0162] Moreover, the sustaining means 425 comprise means for securing the product to the
sustaining means, which, according to a preferred embodiment, are, in particular,
formed by means which are inserted in a corresponding part, or hole, in the product
11.
[0163] In practice, screw means 426 are provided, which are inserted in a corresponding
hole 425c in the sustaining body 125 and in a further hole 11a made in the product
11, that is to say, a hole which opens in a corresponding face of the product 11 for
engaging with the sustaining body 125, or means whose respective front or end face
engages with a corresponding portion of the product to be retained.
[0164] As illustrated, the fixing means 426 extend in a respective hole which is vertical
or perpendicular relative to the base unit 425, or for the third embodiment "g" of
the holder, in a respective hole which is horizontal or extending in the plane in
which the base unit 425 lies.
[0165] In particular, as illustrated, in the fixing means for the second holder "f", the
fixing means 426 extend upwards, projecting beyond the upper face 111c of the base
unit.
[0166] As shown in Figure 13, the auxiliary sustaining means are in the form of a body or
base unit 425 whose plan view extension substantially covers the entire plan view
extension of the supporting panel 12.
[0167] It shall also be understood that, in the embodiments illustrated, although preferably
being positioned below the retaining and supporting panel 12, the vibration motor
30 could also be positioned above the panel 12, or even at the side of the panel 12.
[0168] The treatment composition may be like that illustrated in document
WO 00/32355.
[0169] The invention described is susceptible of industrial application. Moreover, it would
be obvious to experts in the field that several changes and/or modifications can be
made to the invention without departing from the scope of the invention, as defined
by the appended claims.
