Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a machine for preparing
food products.
[0002] The machine for preparing food products according to the
present invention is particularly but not exclusively useful for
preparing products such as pasta and the like and more particularly
for lasagne.
[0003] Currently, the preparation of multilayer food products, such
as for example lasagne, uses devices which are unable to ensure a
high production rate per unit time.
SUMMARY OF THE INVENTION
[0004] The aim of the present invention is to provide a machine for
preparing food products, particularly lasagne and the like, having
productivity and functionality characteristics distinctly superior
to those of hitherto known machines.
[0005] Within this aim, an object of the invention is to provide a

hygiene of the product during the process steps.
[0007] This aim and these and other objects which will become
better apparent hereinafter are achieved by a machine for preparing
food products, comprising a feeder, which is suitable to take a
plurality of lines of product and to feed each one of said lines to
a respective product conveyor, and means for distributing food
product of each line in order to distribute such product in
respective containers fed by means of a conveyance device,
characterized in that said product conveyors extend parallel to
each other and one above the other and have different lengths, each
product conveyor having a delivery end at a distribution station
which is suitable to deposit the product, which arrives from the
respective product conveyor, in a container which is supplied to
said distribution station by said conveyance device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] With reference to the figures, the machine for preparing
food products according to the invention, generally designated by
the reference numeral 1, comprises a frame 2 which supports a
plurality of conveyors 3 of a food product which is fed to the
product conveyors 3 by means of a feeder 4 which is suitable to
take the product from a production line 5.
[0015] Each conveyor 3 consists of a conveyor belt which runs
substantially longitudinally along the frame and has a first end
for receiving the product and a second delivery end 6 at which
there is a distribution station 7 suitable to distribute the
product, which arrives from the deliver end 6 of the product
conveyor 3, in a container 8 being conveyed by a container conveyor
which is constituted, in the specific case, by a chain conveyor
9.
[0016] The product conveyors 3 are arranged one above the other and
have different lengths, so that the delivery ends 6 are spaced one
another, preferably with a uniform distance. Likewise, the
corresponding distribution stations 7 are spaced, and arranged on
the same plane, along the container conveyor 9.
[0017] Reference is now made, in the following, to the processing
of a product constituted by pasta in the form of a continuous strip
for producing, for example, lasagne, which as is known is formed of
a series of layers of pasta interleaved with sauces, grated cheese,
and any other selected products, such as vegetables, ham,
etcetera.
[0018] The pasta in the form of a continuous strip that arrives
from the production line 5 is cut longitudinally in order to form a
plurality of strips of pasta 10 which are conveyed, by the feeder
4, to superimposed positions and are fed to each one of the product
conveyors 3. The illustrated example shows four product conveyors 3
which are suitable to form four layers of pasta in each container
8, but it is evident to the skilled in the field that the number of
product conveyors can vary according to the requirements.
[0019] The continuous strip of pasta 10 of each conveyor is fed
from the delivery end 6 to the distribution station 7 by gravity,
where it is received by a guiding element 11 which is assisted by a
roller 23 for guiding the strip 10 into a cutting device 12. The
cutting device 12 is suitable to cut the strip 10 in order to form
a series of sheets 110 which are received by a receiving and
unloading device 13 suitable to unload the sheet 110 in a container
8 which is conveniently arranged at the unloading end 14 of the
receiving and unloading device 13.
[0020] In greater detail, the cutting device 12 comprises two
blades 15, each of which is actuated by a respective actuator 16;
the blades are suitable to act, with a scissor-like action, on the
pasta strip 10 in order to achieve a precise and rapid cut in said
strip.
[0021] The receiving and unloading device 13 comprises a conveyor
belt 17 which is actuated by a pulley 18 and forms an upper
inclined surface 19 on which the strip 10 and the sheet 110
generated on cutting the strip 10 are placed.
[0022] At the inclined plane 19 an expulsion device 20 is also
provided, formed by a plate 21 which is actuated by actuators 22
and can move transversely on the inclined plane 19 in order to
expel a sheet 110 from the distribution station 7 during machine
startup, as described hereinafter.
[0023] The container conveyor 9 is suitable to supply a container 8
to each distribution station, at the unloading end 14, so that the
container slides with respect to delivery end at a speed which is
appropriately synchronized with the movement of the conveyor belt
17, so that the sheet 110 is laid flat inside the container.
[0024] The conveyor 9 is constituted, in the specific case, by a
chain conveyor which comprises a series of evenly spaced pins for
moving a plurality of containers 8.
[0025] In the illustrated example, the chain conveyor 9 comprises
two lateral chains 24 provided with lateral pins 25 and a central
chain 26 provided with central pins 27.
[0026] The two chains 24 and the central chain 27 are actuated by
an actuation sprocket system 28 comprising two lateral sprockets 29
and a central sprocket 30. The central sprocket 30 rotates freely
with respect to the lateral sprockets 29 but can be locked with
respect to them in at least two positions: one in which the central
pins 27 are staggered with respect to the lateral pins 25, shown
for example in FIG. 8, and one in which the central pins 27 are
aligned with the lateral pins 25. In this manner it is possible to
adapt the conveyor 9 to different formats of the container with an
extremely rapid operation consisting in releasing and locking the
central sprocket 30 of the actuation sprocket system 28.
[0027] The movement of the chain conveyor 9 is synchronized with
the movement of the conveyor belt 17, of each distribution station
7, and with the movement of the product conveyors 3.
[0028] Advantageously, such synchronization is achieved with a
single motor (not shown) which, in addition to actuating the chain
conveyor 9, through the shaft 33 on which the actuation sprocket
system 28 is fixed, actuates also an actuation shaft 31 which
extends under and along the chain conveyor 9 and which, by means of
appropriate transmission mechanisms 32, actuates the conveyor belts
17 of the distribution stations 7 and the product conveyors 3.
[0029] In an intermediate position between the distribution
stations 7, dispensing stations 34 are also provided which are
suitable to dispense food products into the containers 8 conveyed
by the chain conveyor 9.
[0030] The operation of the machine according to the invention is
now described with reference to the preparation of lasagne and to
the embodiment shown by way of an example in the drawings.
[0031] A continuous strip of pasta, produced by a production line
5, is cut longitudinally in order to generate four continuous
strips of pasta 10 which are stacked by a feeder 4 so that each
strip of pasta 10 is supplied to a respective product conveyor
3.
[0032] The strips of pasta 10 therefore advance simultaneously on
all the conveyors 3. In steady-state operation, the first strip of
pasta 10, conveyed by the lowermost conveyor 3 with reference to
FIG. 1, reaches the delivery end 6 and descends into the first
distribution station 7, which is the first station to the right
with reference to FIG. 1.
[0033] The strip of pasta 10 is received by the guiding element 11
and, being assisted by the roller 23 and by the advancement
movement, to the left with particular reference to FIGS. 3 to 6, of
the inclined plane 19 of the conveyor belt 17, is deposited onto
said inclined plane. At a preset time, the cutting device 12 cuts
the strip 10, forming a sheet 110 which is deposited on the
inclined plane 19 and is conveyed thereby, as shown in FIG. 4.
[0034] The advancement of the inclined-plane portion 19 of the
conveyor belt 17 carries the sheet 110 beyond the unloading end 14,
where the sheet is unloaded into a container 8 which is
appropriately supplied at the right moment at the unloading end 14
by the movement of the chain conveyor 9 (FIG. 5).
[0035] The sheet of pasta 110 is adequately laid flat on the bottom
of the container by the synchronized advancements of the
inclined-plane portion 19 of the conveyor belt 17 and of the chain
conveyor 9, as shown schematically in FIG. 6.
[0036] The container 8, in which the first sheet of pasta 110 has
been laid flat, passes from a food product dispensing station 34,
which dispenses a product, for example a sauce, onto the first
sheet of pasta. Then the container 8 reaches the second
distribution station, where a second sheet of pasta 110 is laid
flat in a manner which is fully similar to what has been described
for the first distribution station. The same operation is repeated
in the subsequent distribution stations and dispensing stations,
and at the end of the process the containers 8, complete with the
prepared product, appear in succession at the leftmost end of the
machine with reference to FIG. 1. The containers thus prepared can
then proceed to the subsequent provided processing steps, of a per
se known kind.
[0037] In the steady-state operation of the machine, these
operations occur simultaneously for several containers in all the
distribution stations and dispensing stations; however, depending
on the type of product to be packaged, one or more of the stations
or product conveyors can be deactivated in order to prepare a
product with two or three layers of pasta instead of four.
[0038] At the beginning of the process, therefore before
steady-state operation is reached, it is necessary to eliminate the
first sheets produced by the first distribution stations, starting
from the rightmost one with reference to FIG. 1, since any first
sheet 110 laid flat on a first container 8 would not be able to
receive a second sheet from the second station, since the second
strip of pasta would not have reached yet the delivery end 6 of the
second conveyor 3.
[0039] For this reason, the expulsion devices 20 of the
distribution stations are actuated in order to expel the sheets 110
toward one side of the machine, as shown schematically by an arrow
in FIG. 8, so as to prevent them from falling onto the chain
conveyor or in any case interfering with the subsequent
steady-state operation of the machine.
[0040] The various elements of the machine that come into contact
with the food products can be cleaned easily, optionally by
removing them from the machine, as occurs for example for the
conveyor belts of the product conveyors 3 and the conveyor belts 17
of the distribution stations 7. To these end, the guiding pulleys
are fixed to a coupling which can move longitudinally in order to
slacken the tension of the belt and allow the removal thereof.
[0041] In practice it has been found that the invention achieves
the intended aim and objects, a machine for preparing food
products, particularly lasagne and the like, having been provided
which has productivity and functionality characteristics which are
distinctly superior to those of the machines used up to now.
[0042] The machine according to the invention is susceptible of
numerous modifications and variations, all of which are within the
scope of the appended claims; all the details may further be
replaced with technically equivalent elements.
[0043] The materials used, as well as the dimensions, may of course
be any according to requirements and to the state of the art.
