[0001] The invention relates to a manufacturing machine, in particular a machine for the
processing of tobacco or for the packaging of cigarettes or similar, of the modular
type.
[0002] The aim of the invention is the one to create a machine of the above-mentioned type
with features of modularity such that take into consideration diverse operational
units that are foreseen in the same machine allowing for a subdivision in modules
according to a logic that covers at least in substance the operational plans and that
allow to load the manufacturing machine with ease into containers, allowing to minimize
the number of the same thanks thanks to a better use of the loading volume available.
[0003] The invention aims at obtaining the above-mentioned purposes thanks to a modular
construction that at the same time makes the manufacture and assembly of the machine
less costly and more flexible.
[0004] From the patent application EP 816714 of the same holder is known to realize a modular
machine in such a manner that the same be formed by a bed in shape of a table with
prearranged coulpings for the operating, drive and control units, made in form of
small boxes, the couplings of the small boxes being prearranged between each other
and the table.
[0005] The invention aims at perfectioning this type of construction.
[0006] The invention attains the above-mentioned purposes with a manufacturing machine of
the type described at the beginning in which the bed is formed by a plurality of modular
support frames made in shape of a table with dimensions substantially equal or of
the same order of magnitude and that can be fixed in a movable manner to each other,
while a plurality of operating, control, drive and supply and guide units for the
feeding and control installations are provided that are made in form of modular prefabricated
units and that have couplings prearranged to mate with coupling means these also prearranged
on modular support structures.
[0007] Each modular support structure in form of a table is associated with preset modular
prefabricated units that can be at least for the majority of the said modular units
assembled beforehand on their corresponding modules in their substantially final position
before the positioning and coupling of the frame modules to each other, the operating
units being connected to one other and supported by adjacent frame modules in form
of a table positioned in the correct working position, so that upon the relative positioning
and connection of the framework modules to each other the operating units come to
be in their relative substantially correct working position, with exception for possible
positioning tolerances. These will have to be eventually corrected during the phase
of assembly to each of the individual modular frameworks in shape of a table.
[0008] According to one perfectioning, the dimensions of the individual framework modules
equipped with the modular units fitted on the same are commensurate to the volumetrics
of the containers, in order to be able to house the maximum possible number of the
said frame modules with the pre-assembled modular units in the smallest number of
containers.
[0009] Advantageously the machine is equipped with at least one channel for housing the
cables, conduits or other link-up parts of the supply , control installations and
of other type that extends itself in direction of the longitudinal extension of the
machine and that at least one channel is made in modular segments each of which is
connected to a modular framework in shape of a table, as the individual channel segments
can be connected in a movable manner to each other upon their assembly to each other
of the bed frame modules in shape of a table.
[0010] Advantageously for this purpose, the channel is made in form of a longitdinal tubular
part suspended in the rear top section of the total dimension in height of the machine,
each segment of the channel being supported by a pair of vertical risers connected
on the sides of the frame modules in shape of a table of reciprocal connection and
on the end sides of the external modules.
[0011] Advantageously the channel extends itself along the entire rear side of the machine,
wuile a cabinet containing the control and drive modules is provided that is also
modular and with a longitudinal extension parallel to the one of the framework in
shape of a table in the assembled condition.
[0012] The cables and conduits and the other lines of supply, control and for the execution
of sending or the transmission and reception of other signals or fluids, advantageously
branch out from a distribution module that is foreseen in a segment of a channel connected
to an intermediate framework module in shape of a table.
[0013] Preferably the distribution box itself is formed by said segment of channel from
which depart the branching conduits to the cabinet.
[0014] According to a further feature, the housing of the cables, conduits or other supply,
control lines, etc. is foreseen in the disassembled condition of the individual framework
modules in shape of a table and that is formed by the distribution segment of the
guide channel of the conduits, the cables and of the lines, and inside of which during
transport are folded in the sections of the cables, of the conduits and other lines
designed to run in the additional segments of the channel associated with the additional
modules of the frame in shape of a table to connect themselves to the modular units
assembled on the same.
[0015] This realization has the remarkable advantage of not having to provide for branching
out the lines during the assembly of the machine after transport. The branches can
be made in a fixed manner during the manufacture and assembly of the intermediate
module the channel segment of which forms the distribution box. During the assembly
of the machine, after having connected the individual frame modules in shape of a
table to each other and the associated segments of the channel, it is only necessary
to fold back the parts of the cables and conduits designed to reach the modular units
associated with the additional frame modules in shape of a table, that is to other
modules of the machine passing them through into the additional segments of the channel
and connecting the plugs or the couplings to the operating units provided.
[0016] According to a further perfectioning, the machine has a framework for the protection
screens and parts or for possible other guards that is itself also made in a modular
manner, the individual modules being subdivided correspondingly to the frame modules
in shape of a table, analogous to the channel for the cabels and conduits.
[0017] A particular form of execution foresees that each framework module in form of a table
has a support frame for the screens, the guards or similar means of protection and
that the support frames of said screens or similar of protection and/or the screens
themselves modularly complete each other, in the assembled condition one to the other
of the frame modules in shape a table.
[0018] Each modular support frame of the protection screens or similar associated with each
modular framework in shape of a table has furthermore its own hinged means to move
into open or closed position part of the screens, or similar in shape of a wing or
door.
[0019] According to an advantageous realization the protection screens or similar are made
in the shape of a part suspended projecting on the frame in shape of a table and have
such a span as to cover the top side and the service one on the front associated with
the corresponding frame module in shape of a table.
[0020] In this case, each screen associated with each modular frame in shape of a table
is made with transversal sections substantially in shape of an L with a substantially
horizontal top branch and a front branch substantially vertical that join together
in a rounded manner, while the free end of the top horizontal branch is hinged to
a mechanism of articulation supported by a segment of a beam substantially parallel
to the segment of the channel for the cables and conduits and the lines or to the
said segment of the channel itself.
[0021] The mechanism of articulation, furthermore is formed in shape of an articulated parallelogram
of such dimensions, that the lifting of the screen from the closed position to the
open one takes place substantially in the vertical direction, or else substantially
parallel to the vertical branch of the said screen for a section corresponding to
the mean height of a human being, while in the remaining part it also move additonally
transversally rearward to also free the top part of the units associated with the
corresponding modular frame in shape of a table.
[0022] The invention has additional features that are subject of the claims below.
[0023] The features of the invention and the advantages deriving therefrom are better evidenced
in the following description of a non limiting executive example illustrated in the
attached drawings, in which:
The Fig.s 1 and 2 show two perspective views from different angles one on the front
side and the other on the rear side of a machine formed by a pluratity of modular
bed frames in shape of a table according to the invention.
The Fig. 3 is a view analogous to the Fig. 1 but with a protection part in shape of
a screen or similar associated with a modular frame in shape of a table, while the
adjacent modular frames have only the means of articulation of the protection screen.
The Fig.s 4 to 6 illustrate a lateral view on a machine according to the Fig. 3 with
the protection screen in closed position in an intermediate position of opening and
in open position.
[0024] With reference to Fig. 1 a machine according to the invention, in particular a machine
for processing tobacco and more specifically a machine for packaging of cigarettes
has a support bed of the individual operating units made in form of a table 1. This
frame in shape of a table 1 is of the type as for example described in the patent
EP816714 of the same holder. In this construction, the operating units, the transmission
units and the drive units are realized prefabricated each in shape of an independent
modular assembly with its own support frame or box, that is provided with prearranged
mounting means to, on or in housings of the frame in shape of a table.
[0025] In this case, in the example illustrated the modular operating, transmission and
drive units are not illustrated in detail, as these are not part of the present invention.
The frame in shape of a table is instead subdivided into individual modular sections
101, 201, 301. The subdivisions are made transversally to the longitudinal extension
of the machine, but this is only an example and does not constitute a limiting feature,
as according to the topology of the machine it is possible to foresee also other types
of subdivisions.
[0026] Each module 101, 201, 301, of the framework in shape of a table is therefore designed
to be secured in a movable manner to the adjacent module. The clamping can be made
thanks to any means as screw type means and can be provided also with truing means
such as truing dowels cooperating with truing holes, eventually the dowels and holes
being partially conical and provided with automatic truing surfaces such as inclined
planes, or similar.
[0027] The lines of subdivision between the individual modules 101, 201, 301 of the frame
in shape of a table 1 are preferably made in such a manner to allow the assembly on
said module of the major part of the modular operating, transmission and supply units
and eventually also following a certain logic of the manufacturing process the machine
has to carry out. Furthermore, the subdivisions between the modules 101, 201, 301
of the frame in shape of a table are chosen in such a manner, that the dimensions
of the same are suited to the dimensions of the loading volume of the containers,
in that it is possible to load the machine in the smallest number of containers possible
and to exploit in full the volumetric load capacity.
[0028] Thanks to these features, each module 101, 201, 301 of the frame in shape of a table
1 can be prefabricated in the factory of the major part of the modular operating,
transmission and drive units and can find place in a container as a placement and
loading of the same is possible independently from the remaining modules of the frame
in shape of a table.
[0029] Generally the standard dimensions in height and width of the different packagings
for the different means of the transport are in the order of magnitude of approximately
200 cm to approximately 240 cm, while in order to allow a sufficent ease of handling
the packagings can not exceed 500 cm in lentgh. In this case, for example according
to the different requirements it is possible to foresee modules with a depth of approximately
200 cm and that in length are a submultiple of approximately 500 cm dependent upon
the number of modules.
[0030] The loading or packaging of the modules of frame in shape of a table 101, 201, 301
separately of each other is certainlly facilitated, while the assembly of the machine
in the stationing of utilization is facilitated by the fact that the same is prefrabicated.
Apart from these simple reasons, also to be considered should be that parts of smaller
dimensions and mechanically seperated from each other are less subject to deformations
and mechanical stresses during transport. Therefore with a single and rigid frame
the parts pre-assembled before transport, upon arrival, may be found to have shifted
or not to be suitably adjusted. In the machine with a structure according to the invention,
the individual operating units on the individaul modules of the frame in shape of
a table have to be adjusted in any case relative to each other and in each case the
structure itself not in one piece considerably simplifies these operations.
[0031] With reference to a further feature of the invention, as well as the frame in shape
of a table subdivided into modules 101, 201, 301, the machine according to the invention
has at least one channel, in particular two channels of distribution of the cables,
conduits or other lines of supply, control or for other functions. This channel or
channels 2, 3 extend themselves advantageously in a position of non interference and
in a preferential manner along the rear longitudinal side of the machine, especially
in an upper position, or in any case in the area of the maximium top dimensions of
the machine.
[0032] The distribution channels 2, 3, are supported in this case by risers 4 that are provided
in pairs on the opposite end sides of each module 101, 201, 301 of the frame in shape
of a table 1. Therefore adjacent modules 101, 201, 301 have also adjacent risers 4.
The risers 4 on the adjacent end sides of reciprocal clamping of the modules of the
frame in shape of a table 101, 201, 301, are furthermore made in such a manner to
form together one column. The distribution channels 2, 3 are themselves also made
modular as they are formed by individual segments 102, 103, 202, 203, 302, 303 of
a length corresponding to the dimensions of the associated module 101, 201, 301 of
the frame in shape of a table 1. Therefore each module of the frame in shape of a
table 101, 201, 301 has preassembled on the same in addition to the modular operating
units of transmission and of drive also its own section of the channel or channels
of distribution.
[0033] The branchings 402, 403 from the channel or channels 2, 3 to a cabinet containing
the control electronics and other drive and control units, as well as eventually the
generators are provided in correspondence to one of the modular segments 202, 203
of the channels 2, 3, preferably in correpondence to a modular segment of the channel
202, 302 associated with a module 201 of the frame in shape of a table in intermediate
position. The volume of the internal space of the channels or in particular eventually
only of the segments 202, 302 equipped with the branchings 402, 403 is such to house
in disassembled condition of the modules 101, 201, 301 of the frame in shape of a
table 1 and therefore of the segments of the channel 102, 202, 302, 103, 203, 303
in a position folded back on themselves also the cables and the eventual control supply
lines and/or for other purposes that in the assembled condition of the channels 2,
3 extend themselves into the segments 102, 302, 103, 303 of the modules 101, 301 of
the frame 1 in shape of a table adjacent to the intermediate one 201 of which the
channel segments 202, 302 have the branchings 402, 403. In this manner, it is possible
to reduce to a minmum the sectioning of the cables and of the conduits and furthermore
to prearrange the same in the channel segments 202, 302 associated with the intermediate
module 201 of the frame in shape of a table 1. During assembly, therefore it is sufficient
to fold out of the segments 202, 302 of the channel 2, 3 the parts of the cables and
of the conduits that have to extend themselves into the adjacent segments 102, 103,
302, 303, to house these in said segments and connect the end connectors of the cables
and/or conduits to the corresponding operating units and/or of control. The channels
2, 3 or rather the modular segments that form them can be open on top or equipped
with top covers both whole as well as segmented corresponding to the modular segments
of the channel 2, 3 and that can be movable, for example foldable, or in any case
removable.
[0034] A movable cover 6 is fixed to a longitudinal beam that is substantially segmented
corresponding to the modular segments of the channel 2, 3 and is parrallel to the
channel or channels 2, 3 itself and substantially extends itself at the level of said
channels, or is advantageously formed by the same channels 2, 3. Also this cover 6
is made modular, or rather is formed by individual covering segments that complete
each other in order to form a single cover and that are divided between each other
in a manner corresponding to the modules 101, 201, 301 of the frame in shape of a
table 1. Each module 101, 201, 301 of the frame in shape of a table 1 has therefore
its own cover section 205. This one can also be fixed beforehand to the corresponding
part of the beam of the channel 201, 301, 202, 302, 103, 303, before the recripocal
assembly of the modules 101, 201, 301 of the frame in shape of a table 1.
[0035] With regards to the rear and top position of the support beam of the segments 205
of the cover 5, the said cover 5 and the corresponding modules are made in a shape
substantially in form of an L with a branch 305 substantially horizontal and on top
that covers the machine on the top and a vertical branch 405 that covers the front
part and that can extend itself up to the edge of the plane of the modules 101, 201,
301 of the frame in shape of a table 1 or if necessary down to the floor.
[0036] Advantageously at least part of the segment of the cover, preferably the entire cover
segment is fixed to the corresponding segment of the beam or channel 103, 203, 303,
in an upwards turnable manner. In particular, the cover segments 205 are supported
projecting from the front side of the segment of the beam or of the channel 103, 203,
303 and are articulated in an oscillating manner around a horizontal axis.
[0037] To be noted is that in the closed position, the cover segments 205 do not exceed
the total dimension in height defined by the top side of the channel 2, 3. Advantageously
the cover segments 205 are further articulated projecting on the front side of the
segment of the beam or of the modular segment of the channel 103, 203, 303 thanks
to a device of articulation in form of an articulated parallelogram overall indicated
with 7 and that has a mounting plate 107 carried projecting by a pair of arms of articulation
207, 307 provided on each head of the plate and articulated respectively in correspondence
to the front edge and the rear one of the said plate 107, while the opposite extremities
of the arms 207, 307 are articulated in vertically distanced points 407, 507 on the
front side of the corresponding segment of the beam of the channel 103, 203, 303.
The motion of opening and closing can be obtained in different ways, for example by
means of linear actuators 8 positioned as indicated in Fig. 3 and that act between
the plane of the corresponding module 101, 201, 301 of the frame in shape of a table
1 and the horizontal internal branch of the cover segment 205 or thanks to motors
that drive one of the axis of articulation of the device of articulation 7. It is
possible to also provide opening and closing shock absorbers.
[0038] The mounting plate 107 extends itself for substantially the entire length of the
cover segment 205 and is substantially horizontal in the position of closure of the
cover 5. The cover segments 205 can be mounted in a movable manner on the said plate
107 in any which way.
[0039] In the Fig.s 4 to 6, a transversal section of a module 101, 201, 301 of the frame
in shape of a table 1 is illustrated, with the columns 4, the channel 2, 3 or a generic
beam and with the corresponding cover module 205. As is evidenced the total dimension
in height of the machine is calibrated on the mean height of a man with his arm raised
and furthermore, the fulcra of the device of articulation 7 are illustrated and with
dotted lines the arms 207, 307 of the same. The length of the arms and the position
of the fulcra is such, that during the upward angular movement of the cover module
205, the vertical branch of the same carries out at least for part of the motion a
movement substantially rectilinear or vertical or in any case substantially parallel
to itself, or with a very much reduced component of movement outward in the direction
of the front of the machine. The outward movement takes place only and in a limited
dimension at the end part of the angular motion in direction of opening of the cover
segment 205. To limit the front dimension towards the outside, besides, the long section
of the free bottom edge of the cover segments 205 is slighty folded back inward for
a certain length of the vertical extension of said vertical branch of the cover 5.
This type of opening motion of the cover 5, allows to limit the dimension required
by the machine, as well as to avoid danger for the servicing personnel.
