    PALLETIZATION DEVICE
    The present invention relates to a palletizing device.
    Document FR-2 781 471 describes a layer-by-layer palletising device. As illustrated in Figure 1, this device comprises: - a first elevator 10 provided for moving vertically and downwardly a pallet during its filling, - a second elevator 12 provided for moving vertically and upward an empty pallet 14, - a first actuator 16 provided for translating an empty pallet 14 'of the second elevator 12 to the first elevator 10 and ensuring its maintenance during the removal of at least one layer 18 until the first elevator 10 supports said pallet 14' a false pallet 20 positioned above the first elevator 10 and the first actuator 16, configured to support bags during the formation of a layer and comprising two movable plates 20a and 20b, - a bag feeding system 22, - a second actuator 24 for gripping the bags from the bag feeding system 22 and depositing them in a given arrangement on the false pallet 20
    In addition, the device comprises an evacuation conveyor 26 of the full pallets and a supply conveyor 28 in empty pallets.
    The operating principle of this palletizing device is as follows. The second actuator 24 seizes the bags, one by one, at the level of the bag supply system 22 and deposits them in a given arrangement on the false pallet 20. When a layer is finalized, the two plates 20a and 20b are spaced apart so that the just formed layer is deposited on an empty pallet held by the first actuator 16 or on the last deposited layer 18 on the pallet. With the exception of the first layer or layers, the pallet is held by the first elevator 10 during its filling. The latter holds and moves it so that the last deposited layer 18 is positioned just below the false pallet 20. Therefore, as the layers are removed, the first elevator 10 goes down.
    When filling a pallet, the first actuator 16 is shifted to the left. In a first step, the second elevator 12 is positioned at the same level as the supply conveyor 28 in empty pallets so that an empty pallet 14 is translated from said supply conveyor 28 to the second elevator 12. a second step, the second elevator 12 is translated upwardly so as to position the empty pallet 14 'at the same level as the first actuator 16, the height that an empty pallet must occupy to receive a first layer formed on the false pallet 20.
    When a pallet is full, the first elevator 10 is positioned at the evacuation conveyor 26 and the full pallet is translated to said evacuation conveyor 26. At the same time, the first actuator 16 grasps the empty pallet 14 and the positioned in the false pallet 20. During this time, the second actuator 24 arranges a new layer on the false pallet 20 which is positioned as soon as it is finalized on the empty pallet 14 'held by the first actuator 16. As soon as the first layer is removed 18, the first actuator 16 vertically moves down the pallet so as to allow the removal of a new layer. Thus, the first actuator 16 maintains the pallet 14 'until the first elevator 10 rises and maintains the pallet 14'. The vertical stroke of the first actuator 16 is short and functions in particular the travel time of the first elevator 10.
    According to a variant illustrated in Figure 1, the palletizing device comprises a frame 30 positioned above the false pallet 20 to form the layer of bags positioned on the false pallet 20. This frame 30 may comprise movable sides that s' away from and approach the layer formed on the false pallet 20 so as to improve the conformation of said layer. Even if it is efficient, the device of the prior art has a relatively large footprint and requires two actuators that outweigh the price of the device and make it more complex. According to another problem, in certain cases, it is difficult to center the pallet with respect to the layers of palletized products. The invention aims to overcome the disadvantages of the prior art. For this purpose, the subject of the invention is a device for palletizing products on supports such as pallets for example, which comprises: an elevator configured to support a support during its filling, said elevator being vertically movable; false pallet positioned above the elevator and which comprises at least one plate movable between a first position of forming a product layer on said false pallet and a second position of depositing said layer on the support or the last layer deposited on the support, - an actuator for positioning the products on the false pallet.
    According to the invention, the palletizing device is characterized in that: the actuator comprises a system for gripping a support configured to deposit a support on the false pallet, and in that the palletizing device comprises a frame lower positioned below the false pallet to center the support or a layer of products relative to the products positioned on the false pallet.
    According to the invention, the support is introduced from the top and deposited on the false pallet using the same actuator as the products. The lower frame makes it possible to center the support and thus to improve the centering of the deposited product layers with respect to the support.
    According to other features: - the lower frame comprises at least one movable side between a close position and a position away from the support or layers of products positioned on the support. - The palletizing device comprises an upper frame positioned above the false pallet, the lower frame being positioned in line with the upper frame. the actuator comprises a head which comprises two L-shaped moving parts each comprising in the lower part a half-plate, and at least one actuator configured to move the moving parts between a first state in which the half-plates are joined to allow to carry at least one product and a second state in which the half-trays are spaced to allow to enter or deposit the product or products. - The head comprises at least one stop to immobilize in translation the product or products positioned on the half-trays when the head is inclined. - The palletizing device comprises a vibration unit and / or a wrapping unit positioned under the lower frame.
