  products out of packaging lines; these products are removed as and when the storage area in sufficient number to complete a pallet and are then sent to the palletizing facility which

  can also serve more than one storage area.

  The first of these solutions obviously has

  very high costs The second solution is very

  because it needs considerable space.

  to install the storage areas which should be

  FIG. 11 is a partial section of the carriage represented

  10 shown in FIG. 10 executed in the plane X-X of FIG. 10. The installation forming the subject of the invention

  is connected by a feed line (1) to a plurality of

  packaging machines not shown

  on the drawings; each of these conditioning machines

  A certain type of product is conditioned and sent to the supply line and thus to the palletizing plant. An identification device, not shown in the figures, is provided which is arranged upstream of the installation and serves to identify the type of product

  which is sent to the same facility; the device of i-

  dentification provides a different command signal

  for each type of product that arrives at the facility

  tion. The identification device may have

  various forms; for example, one can introduce, immediately

  upstream of the installation, a reader who

  reads special labels that are applied to

  and which, of course, vary according to the type

  of the product It is also possible to provide a

  programmed product, machine condition-

  ment; in this way the products that come to the palletizing plant follow a sequence

  predetermined and therefore they have already been identi-

  In any case, these identification devices are

all already known.

  The installation in question comprises a transpor-

  input valve (3) which is connected to the supply line -6 - and which receives from the latter the products to be palletized;

  the conveyor (3) is of the motorized roller type.

  A plurality of barriers (4) is provided on the conveyor (3), these barriers being arranged in planes perpendicular to the direction of the transport movement of the conveyor (3) and being normally placed under the carrier transport plane (3). ) so as not to impede the transportation of the products;

  the barriers (4) are provided with a movement in direct

  vertically, for example by the action of a cylinder of

  control (26) so that they reach a position

  stoppage (shown in Figure 2) located above

  above the transport plane of the input conveyor (3).

  Barriers (4), the number of which is equal to

  that of the types of products that arrive at the

  tion, are actuated by means of signals provided by the identification device; obviously, depending on the type of product identified by the identification device, and therefore depending on the type of signal sent, it will be

  one or the other of the barriers (4) to be actuated.

  There is also provided a plurality of storage transporters (5) whose number is equal to that of the types of products which are sent simultaneously to the installation; the conveyors (5) are arranged so that one of their ends is next to the conveyor

  (3) and that their direction of transport is

  pendicular to the transport direction of the carrier (3); the ends of the storage conveyors are in a position immediately preceding one of the barriers (4). At the other end of each of the conveyors (5) there is provided a stop device (6) comprising, from a constructive point of view, a moving roller -7-

in the vertical direction.

  Stop devices (6) are normally in

  stopping position, that is to say, they are above

  of the carrier transport plan (5), in such a way as to

  they stop the products passing over the trans-

  carriers (5); the stop devices (6) are brought

  periodically, in ways that will be better described

  subsequently to a position in which they

  with the transport plan of the carriers (5), so that they do not impede the products passing

on carriers (5).

  The conveyors (5) are of the powered roller type; each of the conveyor rollers (5) is provided with a freewheel device so that they can act either as idle rolls or as motorized rollers, depending on the necessities which will be

better illustrated later.

  In order to transport the products of the

  to one of the conveyors (5), first thrust means are provided, each of which comprises a pneumatic control cylinder (13) at the free end of the rod of which is connected a blade (14) which, at following the actuation of the cylinder (13), slides on the plane of

  transporting the conveyor (3) in a perpendicular direction

  re to the direction of transport of the same carrier; as a result of this shift the product intercepted by the

  blade (14) passes from the conveyor (3) to the conveyor (5).

  FIG. 3 shows the direction of movement of the blade (14) and, in broken lines, the position that this blade takes when it pushes a product (for example the

  packet (27)) from the conveyor (3) to the trans-

  carrier (5) The blade can be slidable vertically relative to a small frame (33) fixedly attached to the cylinder rod (13) (see Fig. 5). During its pushing stroke, the blade

  (14) is kept lowered and can thus

  ter the carrier's products (3) to the carrier (5); during its return stroke, the blade is raised, for example by means of a small pneumatic cylinder (34),

  so that the passage of other products is not

  on the contrary, if the blade (14) were fixed In this way the products can be sent to the conveyor (3) more frequently and consequently

  increase the productivity of the installation.

  A presence indicator (15), comprising

  example a photocell is provided relative-

  at each barrier (14); when this indicator signals

  the presence of a product stopped near the bar-

  (4), it provides a control signal for the action

  the cylinder (13) and the subsequent transfer of the

  it is evident that the actuation of one of the cylinders (13) can take place only after the triggering of the identification device; the signal provided by one of the presence indicators (15) will actuate the corresponding cylinder (13) only when the corresponding barrier

  (4), following the signal provided by the identification

  This is in order to avoid undesirable movements of the cylinders (13),

  and therefore blades (14) which could be

  following the passage of products intended to be

  stopped by the following barriers.

  On each storage conveyor (5) it is

  sees metering devices, of known type, which

  count the number of products that pass on the trans-

  carrier; each of these meter devices provides a signal that is likely to allow the release of the

  storing device of the corresponding storage conveyor

  at the same time to allow the output movement of the products of the storage conveyor; this signal is provided by the counter device whenever the number of products counted is equal to the number needed

  to form a flat layer of products on the pallets.

  The number of products which will cause the emission of the signal from the counter device will obviously depend on

their dimensions.

  Products coming out of each of the trans-

  storage carriers are sent, via

  junction conveyor (8), to a device

  mateur (7) capable of forming the plane layers of

  products; both the connecting carrier and the

  trainer are of known type; the operations that

  the training device performs on the products

  of course, of their number and dimensions.

  The movement of products coming out of one of the

  carriers (5) and arrive at the training device (7)

  facilitated by the presence of devices that

  the rotation of the products and supports with idle rollers with a vertical axis

  changes of direction of the same products occur

  duce; as already mentioned above, all these

  positive are in any case of known type.

  The forming device (7) is further provided with second thrust means (28) which, as soon as said

  device formed the flat layer of products,

  pent to push the layer formed outside the device.

  - There is also a counter control device, not shown in the figures but in any case

  of known type (for example formed of photocells

  which provides a signal each time it detects

  passing all the products that make up a complete layer beyond the junction conveyor (8); this signal allows the release of the stop device (6) and the output movement of the products, the storage conveyors (5). In connection with what we have previously said, the clearance of the barriers (4) and the output of the products of the storage conveyors (5) are only allowed when the connecting conveyor (8) is free and when on one of the conveyors (5) there is a sufficient number of products to form a layer of products to be palletized. layer of output products

  of the training device (7) will be formed of products belonging to

  holding all of the same type; the type of product that forms the layer can be easily identified since it is easy to determine which carrier

  the products forming said layer are

  tis. Downstream of the training device (7), provision is made

  a plurality of fixed deposits (9) the number of which is

  gal to that of the types of products; on each of these

  which are essentially composed of a plan of

  motorized pallets, is deposited a pallet on which layers of products of the same type are successively

put in support.

  The plant in question also comprises a first removal device (10), which removes the layers formed by the forming device (7) and presses them on the fixed deposit (9) relating to the type of product 11.

  whose removed layer is formed.

  The device (10) essentially comprises a

  frame (16) which can slide along

  first parallel slides (17) arranged in such a way that they contain the deposits (9) therein; in other words, the device (10) slides above

fixed deposits (9).

  A support frame (18) can slide in direction

  vertically along the frame (16); the plan

  of said frame (18) consists of a rolling device

  idle wheels (19) This idler roller device (19) is slidable with respect to the support frame (18) so that it can assume a first position (shown in Fig. 6) in which it occupies the plane of support, and a second position (shown in Figure 7), in which it does not occupy the support plane In order to allow the sliding of the roller device, the rollers of which it is composed are supported by a pair

  chains (20) which, when ordered, are wound inside the

  a space (21) provided in the support frame,

  side of the support plane of the same frame.

  Alignment means (22) are also provided which are supported on the support frame (18); these means, as shown for example in FIG. 7, comprise a pair of jaws disposed facing each other, which are brought together and spaced from each other by control cylinders.

  make uniform the size of the layer of products dis-

  the support plan so as to ensure both the

  barit full pallets that, above all, their plumb.

  There is also provided a fixed stop (35) which serves to prevent

  expensive that the products deposited on the roller device 12 -

  follow it during its sliding movement.

  Figure 9 shows another possible form

  implementation of the support framework (18), in particular the

  Roller Bearing (19) According to this embodiment the roller device is divided into two parts (19a) and (19b); in this case the rollers are supported by two pairs of chains, (20 a) and (20 b) respectively, which

  curl, on order, inside a first

  empty space (21 a) and a second empty space (21 b) respec-

  tively; these empty spaces are on both sides

  opposed to the support framework support plan.

  According to the embodiment of Figure 9, the sliding of the parts (19a) and (19b) of the roller device takes place in opposite sliding directions with respect to each other; in this embodiment each part of the roller device occupies

  half of the support plan and therefore its

  to abandon the same support plan is more

  faster than in the case of the roller device of FIGS.

  res 6, 7 and 8; however, this embodiment involves some construction difficulties in addition In this case also there is provided a stop (36) which has the same shape and

  the same functions as the stop (35).

  There is also provided a movable stop (37) which, during the loading of the product layer, takes the position shown in FIG. 9 while, after this loading, is carried by means of an endless chain transmission (38). above the support plane (position shown in phantom), in order to compact the layer of products In addition the stop (37) serves to prevent the products follow the part (19 b) during its sliding during the unloading phase 13 -

  For the sake of clarity, in the figures we have

  felt very schematically, or even eliminated all means

  actuating both the frame to amounts along the slides

  (17), that the support frame along the uprights (16), that chains (20) supporting the roller devices (19), these means and their application being part of

known art.

  In addition, detecting means of

  veal, of known type, which detect the maximum height reached by the products deposited on the deposits (9); these level detecting means are capable of providing a control signal, proportional to the maximum detected height, which controls the movement in the vertical direction of the support frame (18) along the upright frame (16) of

  to stop this movement to a slightly

  less than the maximum height detected compared to the

  solution, also adaptable, to raise the framework for

  after each removal of products, until it reaches

  up to the height achieved by the products on the same deposit, the proposed solution obviously leads to a remarkable economy in terms of

  the time required to carry out the operations

  mentioned above, as well as energy savings.

  The level detector means described above

  can easily be obtained, for example memorized

  sequentially carrying out the deposition operations performed by the first removal means, so as to be able to go back to the maximum number of layers deposited on each of the deposits (9) and, consequently, to the maximum height reached by these layers; obviously it will be necessary to have a reset system at the moment when a pallet

  complete will be removed from one of the depots (9).

  The installation in question also includes

  a second removal device (11) for removing

* worm the complete pallets of the deposits (9) and transfer them to an unloading line (2); the device (11) consists essentially of a carriage (23) which slides along second parallel rails (24) developing next to the deposits (9) and the unloading line (2). The carriage (23) is provided with a train

  driven rollers (25) This roller train (25) cuts

  smooth, relative to the carriage (23) by means of blocks of

  sliding (30) which slide inside sliding

  res (29) fixed relative to the carriage; the movement of the roller train (25) relative to the carriage (23) is

  given by a vehicle (32) and a pinion meshing

  rack (31) For simplicity the motor means which cause the sliding of the carriage (23) have been omitted

along the slides (24).

  The carriage (23) is further intended to remove from a pallet deposit (12) the empty pallets which are to be transported on the deposits (9) when a

  pallet was removed from these same deposits.

  p 8 t paletiesvides (12) will obviously be placed near

  slides (24) so that it can easily be

dyed by the carriage (23).

  The operation of the installation object of the

The present invention is as follows.

  Products to be palletised, for example from

  quets (27) of different shapes and sizes, arrive at the input conveyor (3) after being identified by the identification device; as a result of this - identification the device itself emits a signal which

  * controls the raising of one of the barriers (4) and specifies

  the barrier placed immediately downstream of the

  junction between the input carrier (3) and the trans-

  storage carrier (5) relating to the type of product concerned At the same time the corresponding cylinder (13) receives

  the trigger to go into action When the product ar-

  bank against the barrier (4) raised, the indicator of

  sence (15) emits a signal which actuates the cylinder (13) so that the blade (14) gives an energetic thrust to the package (27) causing it to pass on the conveyor (5) During this phase the carrier rollers

  (5), thanks to their freewheel device, act in.

  as idle rolls The operations described above are repeated so that each type of product is

  addressed to its carrier-of, corresponding storage.

  When one of said carriers (5) has been sent a number of products sufficient to form a layer

  the palletizing device, the respective counter device

  initiates the rollers of the conveyor (5) so that the group of products intended to form

  a layer is piled up at the end of the conveyor

  triggering impulse for the lowering of the

  a free channel signal is given.

  Since the groups of products removed must be sufficient to form a layer to be palletized (and

  not a complete pallet), the dimensions can be maintained

  storage transporters (5) are very small,

  which is very advantageous as regards the clutter

  the installation in question; the advantages of this installation increase, by increasing the number of layers necessary to obtain a complete pallet,

  that is to say when the products have a small thickness.

  When the group of products, whose type has been well identified, as previously said, has been arranged by the device (7) in the form of a flat layer, this layer is pushed by the second thrust means (28) onto the roller device (19) of the support frame (18) of the first removal means (10); this operation is performed when the removal means (10) are close to the device (7) and when the support frame has its support plane, occupied by the roller device

  (19), at the same height as the support plane of the

tif trainer (7).

  The support frame then slides along the frame magnets and ascends to a level which is indicated by said level detector means; the

  upright frame moves on the slides (17)

  to reach the deposit (9) for the product whose

  transported layer is formed at the same time as this

  placement, or after it, the means of alignment

  (22), approaching one another at a distance of

  determined, arrange the layer of products

at the exact position.

  When the desired fixed deposit has been reached, the descent of the support frame is

  as close as possible to the plan on which we are

  load the products and cause the sliding of the

  roller arrangement (19) (or roller devices (I Qa) and (19b) if it is a support frame obtained according to the embodiment shown in FIG. way that the layer of products can be supported by

  fall on the pallet placed below.

  The presence of the alignment means (22) and the

  stops (35) (or (36) and (37)) makes it possible to

  different layers exactly on top of each other.

  Then the support framework is raised again, its

  roller bearing still occupying the support plane, and the sliding frame is caused to slide along the slideways so that the removal means (10) return in the vicinity of the forming device (7) in order to

  to remove another layer of products.

  All the movements of the first device of

  described above are controlled by first synchronization means, which are normally of the type

  electronic; the implementation of these means of synchronization

  the application requires no inert effert and can be performed, even with some application, by a technician expert in automations When a pallet has been

  completed in one of the depots (9), it activates the

  riot (23) who is usually in a waiting position

  mid-term; it moves next to the deposit (9) on which is the full pallet; the train

  rolls of the trolley approaches the deposit and the rolls

  motorized water causes the transfer of the

  the trolley (23), after a new

  caliper rearward movement of the roller train (25), 18 - moves in correspondence of the unloading line (2), by sliding on the slideways (24) so that, because of a further advance of the roller train

  (25) and the operation of the same rollers (25), the

  lette is transferred from the carriage (23) to the discharge line

  (2) Then the carriage (23) moves close to

  8 t of empty pallets (12) and, after having

  lifted an empty pallet, depositing it on the depot (9) from which the complete pallet had been removed according to

  similar to those described above.

  This operation is complete, the carriage returns to

  waiting position, waiting for a new com-

mande.

  The movements of the second removal device

  which have just been described are synchronized by

  second electronic synchronization means

  for which the same considerations are valid

  do about the first means of synchronization.

  In addition to the advantages already described, that is to say

  reduced size, flexibility of use, complemen-

  In the automation of operations, the apparatus object of the present invention has another important advantage: it exerts reduced constraints on the products and therefore there is little risk of deterioration of the products, being

  given that the friction between the products and the

  installation, and the maximum specific pressures on individual products, because the products are handled in small groups and without the use of

push bars.

  It is obvious that many modifications can be made to the installation in question without

_ 19 _

  to get away from the framework and the spirit of the invention

  tion. For example, carriers of a different type than those shown may be used, or instead of the sliding plan with

  of the carriage (23), a pair of forks

can remove the pallets.

  We can also change the way of introducing

  in the installation: for example, if the installation is to be used for

  conditioning which have very different productivities

  From each other, two different supply lines can be provided, arranged on both sides of the input conveyor. The number of storage conveyors (and thus fixed deposits) can be arbitrary, depending on the number of product types

  which must be sent simultaneously to the installation.
