[0001] The present invention relates to a piece of equipment for the production of sanitary
ware.
[0002] More in detail, the present invention relates to a piece of equipment for the production
of sanitary ware, such as e.g. washbasins, bidets, WCs, etc., by means of high pressure
casting.
[0003] High pressure casting consists in the introduction, inside a special mold, of slip,
a fluid ceramic mixture which, once shaped, is made to dry and then fired to obtain
the desired manufactured product.
[0004] The molds are usually formed by a plurality of portions, brought close to each other
to form a forming cavity of the ceramic product.
[0005] Unlike traditional casting, high pressure casting is more efficient but requires
greater resistance of the molds to the stresses given by the pressing force.
[0006] In addition, the forming portions have to remain correctly in place during the casting
operation to avoid aesthetic and functional defects in the finished manufactured product.
[0007] A machine is known from patent
EP 2366517 for the production of ceramic products in which the portions of the mold are associated
with gripping means which, after the portions of the mold themselves have been moved
closer to each other to define the forming cavity, are introduced into a tubular clamping
member adapted to contain them during the casting phase.
[0008] In particular, the portions of the mold are associated in a removable manner with
corresponding supporting elements provided with sliding and positioning means, which
allow them to be locked and removed.
[0009] The machine described by
EP 2366517 also comprises inflatable elements, associated with the clamping element, which are
filled during the casting phase to exert pressure on the gripping means, and consequently
on the forming portions, to keep them in position.
[0010] However, this machine of known type has some drawbacks.
[0011] It is not easy to attach the forming portions to the corresponding gripping means,
as they must be correctly aligned with the gripping means themselves in order to engage
with the corresponding guides and must be made to slide relative thereto.
[0012] This process, in addition to being little practical, also requires the manufacture
of a mutual sliding mechanism provided with reduced tolerances in order to achieve
the correct positioning of the various forming portions. In fact, if the forming portions
are not correctly positioned relative to each other, this could give rise to imperfections
in the sanitary ware item thus obtained. This manufacturing complexity translates,
as easily understandable, in an increase of production costs and, therefore, of sale
to the final customer.
[0013] Another drawback consists in the fact that the known type of equipment described
by
EP 2366517 does not allow for easy maintenance and inspection of the forming portions by the
staff after they have been applied to the corresponding gripping means.
[0014] These operations are in fact necessary before proceeding with the casting phase,
as residues or impurities may have been deposited inside the forming portions, which
may then jeopardize the proper success of the sanitary ware item.
[0015] The machine described by
EP 2366517 is also of considerable weight and encumbrance and the use of the inflatable elements
requires the use of special filling means with a fluid under pressure and of pressure
regulation means that affect the costs and structural complexity of the machine.
[0016] Furthermore, the pressure exerted by the inflatable elements is not precisely controllable
and does not ensure an optimal contrast to the pressure exerted by the casting of
the slip.
[0017] As a result, the portions of the mold may be subject to misalignment and displacement
that can jeopardize the proper success of the product.
[0018] The main aim of the present invention is to devise a piece of equipment for the production
of sanitary ware that allows the application and removal of the forming portions to
the corresponding supporting elements in a practical and easy manner.
[0019] Within this aim, one object of the present invention is to devise a piece of equipment
for the production of sanitary ware that allows a quick and precise positioning of
the forming portions on the corresponding supporting elements and that, at the same
time, is easier and cheaper to manufacture than the equipment of known type.
[0020] Another object of the present invention is to allow an easy and practical inspection
and maintenance of the forming portions after they have been applied on the corresponding
gripping means.
[0021] Last but not least, the object of the present invention is to effectively counteract
the pressure exerted by the slip during the casting phase and in particular to exert
an adequate counteracting force on each portion of the mold regardless of their mutual
position.
[0022] Another object of the present invention is to devise a piece of equipment for the
production of sanitary ware that allows overcoming the above mentioned drawbacks of
the prior art within a simple, rational, easy, effective to use and low cost solution.
[0023] The objects set forth above are achieved by the present equipment for the production
of sanitary ware having the characteristics of claim 1.
[0024] Other characteristics and advantages of the present invention will be more evident
from the description of a preferred, but not exclusive, embodiment of a piece of equipment
for the production of sanitary ware, illustrated by way of an indicative, but non-limiting
example, in the attached tables of drawings in which:
Figure 1 is an axonometric view of a piece of equipment according to the invention
without the forming mold;
Figure 2 is an axonometric view of the equipment in Figure 1 provided with the forming
mold with the forming portions in open configuration;
Figure 3 is an axonometric view of the equipment in Figure 2 with the forming portions
in closed configuration;
Figure 4 is an axonometric view of the equipment in Figure 2 with a gripping element
in maintenance configuration;
Figure 5 is an axonometric view of the first displacement means of the equipment in
Figure 2.
[0025] With particular reference to these figures, reference numeral 1 globally indicates
a piece of equipment for the production of sanitary ware.
[0026] The equipment 1 for the production of sanitary ware comprises a load-bearing structure
2, at least one forming mold 3 associated with the load-bearing structure 2 and comprising
a plurality of forming portions 3a,3b,3c movable in mutual approach/spacing apart
to/from an assembly area 25.
[0027] The forming portions 3a,3b,3c are movable between at least one open configuration,
wherein they are spaced apart from each other, and one closed configuration, wherein
they approach each other so as to define at least one forming cavity 4 of a sanitary
ware item. The forming portions 3a,3b,3c are spaced apart from the assembly area 25
in the open configuration and are approached to the assembly area 25 in the closed
configuration.
[0028] By the term "assembly area" is meant the area of the load-bearing structure 2 where
the forming portions 3a,3b,3c are approached to each other to define the forming cavity
4.
[0029] The forming mold 3 may comprise a number of forming portions 3a,3b,3c variable from
two to six depending on the type of sanitary ware to be produced. In the embodiment
shown in the figures, the forming mold 3 comprises four distinct and separate forming
portions 3a,3b,3c, of which a lower portion 3a associated with a resting base 5 associated
with the load-bearing structure 2, two lateral portions 3b and an upper portion 3c.
[0030] Advantageously, the equipment 1 comprises gripping means 6 of the removable type
of at least some of the forming portions 3a,3b,3c, which are movable relative to the
load-bearing structure 2 to displace the forming portions themselves in mutual approach/spacing
apart.
[0031] These gripping means 6, therefore, allow locking and releasing the forming portions
3a,3b,3c, so that they can be quickly and easily positioned and replaced.
[0032] According to the invention, at least one of the forming portions 3a,3b,3c comprises
at least one supporting element 7 of the ferromagnetic type and the gripping means
6 comprises at least one gripping element 6b,6c of the magnetic type adapted to operate
in conjunction with the supporting element 7.
[0033] Preferably, each of the lateral portions 3b and the upper portion 3c are provided
with a corresponding supporting element 7 and the gripping means 6 comprise a lateral
gripping element 6b for each of the lateral portions 3b and an upper gripping element
6c for the upper portion 3c.
[0034] Advantageously, the gripping means 6 also comprise control means, not shown in detail
in the figures, which can be operated to activate/deactivate the magnetic field of
the gripping element 6b,6c. By operating on the control elements, which can e.g. be
of the electrical type, it is therefore possible to easily lock and release the gripping
elements 6b,6c.
[0035] Advantageously, the lateral gripping elements 6b are associated movable in a sliding
manner with the load-bearing structure 2 along a first substantially horizontal direction
26. The displacement of the lateral gripping elements 6b along the first direction
26 is therefore adapted to allow the lateral portions 3b to be mutually approached/spaced
apart.
[0036] More particularly, the equipment 1 comprises first displacement means 27 of the lateral
gripping elements 6b along the first direction 26. The first displacement means 27
may comprise e.g. at least one first actuator 28 operating on at least one of the
lateral gripping elements 6b.
[0037] The first displacement means 27 may comprise a first actuator 28 for each lateral
gripping element 6b or, alternatively, they may comprise a single first actuator 28
and connecting means 29 shifting along the first direction 26 of the lateral gripping
elements 6b as shown in the embodiment represented in the figures.
[0038] More in detail, the connecting means 29 comprise at least one toothed belt kinematically
connected to the lateral gripping elements 6b to allow them to be displaced in the
mutual approach/spacing apart direction along the first direction 26. In other words,
as a result of the action of the first actuator 28, the corresponding lateral gripping
element 6b moves along the first direction 26, thus also dragging the other lateral
gripping element 6b in its displacement by means of the toothed belt 29 with which
both the lateral gripping elements 6b are associated.
[0039] In turn, the upper gripping element 6c is also movable sliding relative to the load-bearing
structure 2 along a second, substantially vertical, direction 30. The upper gripping
element 6c is therefore movable approaching/spacing apart from the resting base 5.
[0040] More particularly, the equipment 1 comprises second displacement means 31 of the
upper gripping element 6c along the second direction 30. The second displacement means
31 are e.g. of the type of a second actuator 32. Advantageously, the equipment 1 also
comprises positioning means 33 of at least one of the gripping elements 6b,6c between
an operating position, wherein it is arranged at an assembly area 25 of the forming
mold 3, and a maintenance position, wherein it is spaced apart from the assembly area
25 and is accessible from the outside.
[0041] In the operating position, therefore, the gripping elements 6b,6c are movable between
the closed configuration and the open configuration, so that their mutual orientation
is the final one, that is the one that allows the definition of the forming cavity
4 in the closed configuration as a result of their mutual approach. In the maintenance
configuration, on the contrary, the gripping elements 6b,6c are moved away from the
assembly area 25 and, in particular, are displaced towards the outside of the load-bearing
structure 2 in order to be easily accessible by an operator.
[0042] In the preferred embodiment shown in the figures, the positioning means 33 comprise
rotation means 34 for rotating at least one of the lateral gripping elements 6b around
a relevant axis 35.
[0043] The lateral gripping elements 6b are therefore able to rotate around a relevant axis
35 to displace from the operating position to the maintenance position and vice versa.
Figure 4 shows one of the lateral gripping elements 6b in the maintenance position.
As can be easily seen, in this position the corresponding lateral portion 3b can be
easily inspected by an operator.
[0044] Furthermore, the positioning means 33 also comprise a shifting assembly 36 of the
upper gripping element 6c along a third direction 37 transverse to said second direction
30.
[0045] The equipment 1 then, comprises at least one containment device 8 of the forming
portions 3a,3b,3c in the closed configuration, associated with the load-bearing structure
2, where the forming mold 3 and the containment device 8 are mutually movable between
a release configuration, wherein the forming mold 3 and the containment device 8 are
spaced apart from each other, and a containment configuration wherein the forming
mold 3 is inserted inside the containment device 8. The containment device 8 is adapted
to contain the forming mold 3 during the casting phase so as to counteract the thrust
exerted by the pressure inside the forming cavity 4 and which tends to move the corresponding
forming portions 3a,3b,3c away from each other.
[0046] Between the load-bearing structure 2 and at least one of either the forming mold
3 or the containment device 8, movement means 9 are therefore interposed which are
adapted to allow their corresponding displacement between the release configuration
and the containment configuration.
[0047] In the preferred embodiment shown in the figures, the movement means 9 comprise a
pair of straight guides 10, e.g. consisting of elongated crossbars that extend horizontally,
associated with the load-bearing structure 2 and a pair of sliding elements 11, each
provided with a plurality of rolling elements 12, associated with the containment
device 8 and which engage with a corresponding straight guide 10. The sliding elements
11 are therefore able to move relative to the load-bearing structure 2 along the direction
defined by the longitudinal extension of the straight guides 10.
[0048] Advantageously, the containment device 8 comprises at least one containment frame
13, containment means 14 associated with the containment frame 13 and comprising in
turn a plurality of pressing bodies 15 adapted to contact the forming portions 3a,3b,3c.
[0049] More particularly, each of the pressing bodies 15 defines at least one relevant stop
surface 15a adapted to contact a corresponding outer surface 16 of the forming portions
3a,3b,3c.
[0050] Depending on the number and conformation of the forming portions 3a,3b,3c, the stop
surfaces 15a of some pressing bodies 15 may also contact the outer surfaces 16 of
the same forming portion 3a,3b,3c.
[0051] In the embodiment shown in the figures, each of the stop surfaces 15a is adapted
to interact with the outer surface 16 of a corresponding forming portion 3a,3b,3c.
[0052] In particular, the outer surface 16 of the forming portions 3b,3c is defined by the
corresponding supporting element 7.
[0053] Advantageously, the pressing bodies 15 are positioned on the containment frame 13
so as to enclose the forming mold 3.
[0054] In the embodiment shown in the figures, the pressing bodies 15 are positioned in
such a way that their stop surfaces 15a are oriented substantially at right angle
relative to the stop surfaces 15a of the adjacent pressing bodies 15.
[0055] The containment means 14 then comprise at least one tensioning element 17 associated
by wrapping with the pressing bodies 15 and the containment device 8 is provided with
traction means 18 operable to move the tensioning element 17 so as to approach the
pressing bodies 15 to the forming portions 3a,3b,3c. More in particular, the tensioning
element 17 is of the type of an inextensible rope or cable that, when brought into
traction by the traction means 18, exerts such a force on the pressing bodies 15 so
as to cause their displacement when approaching the forming portions 3a,3b,3c.
[0056] Appropriately, each of the pressing bodies 15 comprises at least one guide element
19 of the tensioning element 17, the latter being associated sliding with the guide
element itself.
[0057] Advantageously, the traction means 18 comprise at least one traction element 18a
associated movable with the containment frame 13 shifting along a direction of sliding,
identified in the figures with the double arrow 20, approaching/spacing apart from
the forming mold 3 with the latter in the containment configuration. In particular,
as a result of its moving away from the forming mold 3, the traction element 18a displaces
the ends of the tensioning element 17 so as to bring the pressing bodies 15 closer
to the forming mold 3. The greater the displacement of the traction element 18a away
from the forming mold 3, the greater the pressure exerted by the pressing bodies 15
on the respective forming portions 3a,3b,3c.
[0058] In the preferred embodiment shown in the figures, the traction element 18a is associated
with one of the pressing bodies 15.
[0059] More specifically, the traction means 18 comprise an actuating element (not visible
in detail in the figures), e.g. of the type of a fluid-operated cylinder, associated
with the traction element 18a to move it along the direction of sliding 20.
[0060] Advantageously, the containment device 8 comprises oscillation means 21 placed between
the containment frame 13 and the containment means 14, where such oscillation means
21 are adapted to move in rotation at least one of the pressing bodies 15 relative
to the containment frame 13 around at least a first axis X.
[0061] In the preferred embodiment shown in the figures, the oscillation means 21 are positioned
between the containment frame 13 and each of the pressing bodies 15, with the exception
of the pressing body 15 associated with the traction element 18a.
[0062] The oscillation means 21 are adapted to allow the pressing bodies 15 and, in particular,
the corresponding stop surfaces 15a, to follow the inclination of the outer surface
16 of the corresponding forming portion 3a,3b,3c. In fact, since, as anticipated,
the forming mold 3 is composed of a plurality of forming portions 3a,3b,3c separate
from each other, it follows that, in the closed configuration, the corresponding outer
surfaces 16 can be misaligned with each other or have different inclinations. The
oscillation means 21 thus allow the stop surfaces 15a of the pressing bodies 15 to
follow the inclination of the corresponding outer surface 16 with which they operate
in conjunction, so that they can optimally counteract the pressure that is exerted
on the forming portions 3a,3b,3c during the casting phase.
[0063] More particularly, the first axis X is arranged substantially parallel to the stop
surface 15a of the corresponding pressing body 15.
[0064] Preferably, the oscillation means 21 are adapted to allow the rotation of the corresponding
pressing body 15 around at least one second axis Y transverse to the first axis X,
wherein both the first axis X and the second axis Y are substantially parallel to
the corresponding stop surface 15a.
[0065] Appropriately, the oscillation means 21 comprise a plurality of oscillation elements
22 made of elastically yielding material, so as to allow the rotation of the corresponding
pressing body 15 around the corresponding axis X, Y and to allow its return to a neutral
position the instant when the force that caused the rotation thereof is no longer
present. In particular, the oscillation means 21 comprise one or more pairs of oscillation
elements 22 arranged on opposite sides relative to a median plane Xa,Ya containing
the relative axis of rotation X,Y.
[0066] Alternative embodiments to those described and represented here and of a type known
to the technician of the sector, such as, e.g., a spherical joint or the like cannot
however be ruled out.
[0067] In a preferred embodiment, the containment device 8 is adapted to contain the containment
elements 6b, 6c in the containment configuration. The gripping elements 6b, 6c therefore
remain associated with the corresponding forming portions 3b, 3c during the entire
casting phase.
[0068] In this embodiment, the pressing bodies 15 therefore interact with the gripping elements
6b, 6c in the containment configuration and during the casting phase.
[0069] In an alternative embodiment, the gripping elements 6b, 6c are deactivated, so that
the relevant forming portions 3b, 3c are released, substantially at the same time
as the forming mold 3 is inserted into the containment device 8 to achieve the containment
configuration. During the casting phase, only the forming mold 3 is contained inside
the containment device 8, while the gripping elements 6b and 6c remain outside the
containment device itself. In this embodiment, therefore, the gripping elements 6b,
6c are disengaged from the corresponding forming portions 3b, 3c in the containment
configuration, and the forming portions 3b, 3c interact directly with the pressing
bodies 15.
[0070] The operation of the present invention is as follows.
[0071] The forming portions 3b,3c are initially associated with the gripping means 6. In
particular, the magnetic fields of the gripping elements 6b,6c are activated by operating
on the above mentioned control means, which interact with the supporting elements
7 of the forming portions 3a,3b,3c by blocking them. In turn, the lower portion 3a
is constrained to the resting base 5.
[0072] The gripping elements 6b and 6c, initially arranged in the operating position and
in the open configuration, can be moved to the relevant maintenance positions by means
of the positioning means 33, to allow the inspection thereof and possible maintenance
work by an operator.
[0073] Then the gripping elements 6b and 6c can be moved along the first direction 26 and
along the second direction 30 respectively, approaching the assembly area 25 in order
to achieve the closed configuration.
[0074] Once the closed configuration is achieved, the containment device 8 is made to slide
relative to the forming mold 3, using the handling equipment 9, in order to bring
it from the release configuration to the containment configuration.
[0075] When the containment configuration is achieved, the traction means 18 are activated
to tension the tensioning element 17 in order to bring the pressing bodies 15 closer
to the forming mold 3.
[0076] As a result of this approach, the stop surfaces 15a contact the respective outer
surfaces 16 of the forming portions 3a,3b,3c. The stop surface 15a of the pressing
body 15 associated with the traction element 18a serves as a reference surface.
[0077] The stop surfaces 15a of the other pressing bodies 15, as a result of their progressive
approach to the respective outer surfaces 16 take, by means of the oscillation means
21, the same inclination as the outer surfaces themselves.
[0078] In fact, since the outer surfaces 16 of the various forming portions 3a,3b,3c can
take different inclinations, as a result of their displacement in the closed configuration,
the oscillation means 21 allow the respective stop surfaces 15a to rotate around the
first and the second axis X and Y in such a way as to align with the outer surfaces
16 with which they come into contact.
[0079] In particular, when the stop surface 15a of a pressing body 15 interacts with an
outer surface 16 that is inclined relative to the home position of the stop surface
itself, the latter rotates around a corresponding axis X, Y as a result of the action
of the tensioning element 17 and thanks to the compliance of the oscillation elements
22, until it is coplanar with the corresponding outer surface 16. This way, the stop
surfaces 15a contact the corresponding outer surface 16 with all their available extension,
thus succeeding in effectively counteracting the thrust exerted by the pressure inside
the forming cavity 4 during the casting phase.
[0080] The oscillation elements 22 may then be compressed or extended depending on their
position relative to the median plane Xa,Ya containing the axis of rotation X,Y.
[0081] Once the casting phase has been finished, the traction means 18 interrupt their action
on the tensioning element 17, so that the pressing bodies 15 are moved away from the
forming mold 3.
[0082] The containment device 8 can be moved again to the release configuration, so that
the forming portions 3a,3b,3c can be moved to the open configuration to allow the
extraction of the sanitary ware item.
[0083] At this point the forming portions 3b and 3c may be removed from the corresponding
gripping elements 6b and 6c by operating again on the control elements in order to
deactivate the corresponding magnetic fields.
[0084] It has in practice been ascertained that the described invention achieves the intended
objects and in particular the fact is underlined that the equipment to which the present
invention relates, allows, thanks to the presence of the supporting elements and of
the magnetic gripping elements, an easy and rapid positioning and removal of the forming
portions, in order to speed up the manufacturing process of the sanitary ware and
thus reduce the corresponding production costs. This way, the mold change operations
are considerably simplified, compared to the known type of equipment.
[0085] Moreover, the possibility to move the gripping elements between the operating position
and the maintenance position considerably facilitates, compared to the known type
of equipment, the inspection and maintenance operations of the forming portions both
before and after the casting operations.
[0086] Furthermore, the presence of the pressing bodies and of the oscillation means associated
therewith, allows effectively counteracting the pressure acting on the forming portions
during the casting phase.
[0087] In particular, thanks to the oscillation means, the stop surfaces of the pressing
bodies are able to modify the inclination thereof so that they are coplanar to the
outer surfaces of the forming portions.
