Description

I () Palletizer of stacked printed notebooks The present invention relates

  a palletizing device or palletizer for palletizing printed notebooks stacked in the form of cartridges or printed notebooks

  ) stacked in piles (small bundles of notebooks).

  For palletizing packages such as stacks of notebooks

  printed, there are many devices.

  These devices can be divided into two categories, the devices allowing palletization packet by packet and

  those allowing palletization by layers of packages.

  Thus, US-A-4 214 848 discloses a palletizer in which the packages are deposited in successive layers on a pallet. At a palletizer loading station, an operator takes care of positioning the packages relative to each other to form a layer of packages on a transport plate which is lifted to bring the layer of Gold packages to the top of a station. deposit packages on a pallet. The deposition station consists of a lifting support carrying the pallet and positioned inside a frame comprising two platforms moving along the frame around the lifting support. When the packet layer arrives at the deposition station, it is engaged on one of the platforms of the frame located in the extension of the transport plate and where the packets are brought into abutment against a stop element, the pallet resting below said platform. In order to deposit the layer of packages, the platform is driven in translation along the frame which disappears from below the packages blocked against

the stop element.

  GB-A-821 259 also discloses a palletizing device in which a layer of packages is deposited on a platform at the outlet of a supply conveyor, the conveyor and the platform being slightly inclined to

  help the packages to slide from one to the other, the platform

  form being further constituted by free rotating rollers facilitating sliding. Once the layer of packages on the platform, said platform, which can be moved from bottom to top and top to bottom in a frame, is moved to come over a pallet positioned in the frame. In order to deposit the packages, the platform is erased from beneath the packages, the rollers constituting said platform being mounted on drive belts while a roller carried by two arms connected to a rocking lever comes resting at the end of the packet layer and keeps

  these when clearing the platform.

  Also known from FR-A-2 588 844, a palletizer comprising a basket inside which is loaded a layer of packages row by row, a row of

  packages being engaged on the nacelle using a pusher.

  Once a layer of packages has been formed, the nacelle is brought over a pallet and the nacelle is then driven in translation back to the loading station while the pusher keeps the packages in

  place above the palette where they are deposited in layers.

  Such palletizing devices require relatively heavy equipment, occupying a fairly large volume and offering only layer-by-layer palletization, less precise than package-by-package palletization.

or row by row.

  I () For palletizing stacks of printed notebooks, there is also known from DE-A-3107495 a device in which rows of stacks are formed which are pushed one after the other adjacent onto a layer forming table . Once the packet layer is formed, it is pushed onto a transfer table which brings it above a pallet and o a fixed pusher is lowered behind the layer while the transfer table is erased from under the layer of packages which are thus deposited. Such a device does not make it possible to deposit the packages row by row and therefore can only offer a palletization of cartridges in layers of

  cartridges which implies a very heavy structure.

  In DE-A-3712103, the unloading table comprising a layer of packages consists of conveyor belts which are driven in translation while the unloading table is driven in displacement to deposit the

layered packages.

  In WO-A-86/07579, the palletizer is in the form of a fork guided by moving drive means and the teeth of which slide under a package for

  lift it up and step out from under the package to drop it off.

  The loading or unloading of a pallet is carried out

then pack by pack.

  To palletize cartridges of printed notebooks, a palletizer is used as described in FR-A-2 746 780 o the cartridge of printed notebooks is loaded at the exit of a conveyor on a nacelle then bringing the cartridge on a pallet to deposit it . The deposition of the cartridge occurs due to the erasure of the platform of the nacelle 5 from below the cartridge. Such a device is particularly well suited to depositing cartridges of

  large and heavy notebooks.

  Thus, depending on demand, printing companies provide printed notebooks 1n either in the form of batteries (small package size) or in the form of cartridges (large package size). In general, there is then a production line concerning the stacks of notebooks and comprising inter alia a device for palletizing stacks of 15 notebooks and a production line for cartridges of notebooks

  which is associated with a cartridge palletizer.

  In order to limit installation costs and therefore economic profitability, a palletizer has been proposed which can palletize stacks of notebooks but also palletize cartridges. This device is in the form of a robotic articulated gripping arm which picks up the stacks of notebooks or cartridges one by one. Of course, insofar as the notebook cartridges have dimensions and a weight much higher than those of the stacks of notebooks, the structure of the palletizer has been shaped in correspondence and in particular involves a heavy installation occupying a very large volume. Furthermore, the arm picking up the stacks of notebooks or the cartridges one by one, the palletizing speed is not always compatible with the production speed of said stacks or cartridges, in particular

  especially in the case of a very high speed stacker.

  In the case of the same cycle time in use of notebook stacks and in cartridge use, the robotic arm must go faster in stack use since palletization is carried out stack by stack, which requires a much heavier mechanical structure to support kinetic energy transfers. Thus, when 4 or 6 stacks constitute a row, the arm must go 4 or 6 times faster than for a cartridge for the same cycle time. In addition, the gripping part of the articulated arm should be changed when moving from palletizing cartridges to

palletizing stacks of notebooks.

  As a result, there is currently no palletizer

  mixed (cartridge and batteries) satisfactory.

  In order to overcome these drawbacks, the object of the present invention is to propose a palletizer allowing the palletization of notebooks stacked according to an equivalent volume and mass, whether in the form of stacks of notebooks or in the form of cartridges while offering a dimension installation. reasonable and able to operate in particular in conjunction with stacking devices for notebooks

  high speed, without changing the gripper.

  2) To this end, the present invention relates to a palletizer for cartridges or stacks of printed notebooks, comprising an input station where the notebooks arrive either in the form of a row of stacks or in the form of a cartridge, a nacelle for transporting the notebooks which can be moved from the entry station to a pallet and comprising a horizontal receiving plane extending between side walls and suitable for allowing the engagement by sliding of the notebooks from a loading face of 3 () the nacelle using means for transferring the notebooks from the entry station to the nacelle, characterized in that the nacelle comprises a bar extending between the side walls of said nacelle and mounted integrally with means d drive extending along said side walls, the drive means being actuated so as to move the bar between a high loading position of the nacelle, in which said bar frees the entry of the loading face, up to a low position for depositing notebooks on the pallet, in which the bar is held in abutment against the notebooks resting on the nacelle while the nacelle is driven in displacement towards the entry station, so that the bar holds the notebooks while the nacelle's reception plane disappears from

below the notebooks.

  Thus advantageously, whether the notebooks are in I (in the form of cartridges or in the form of a row of batteries, the bar extending between the side walls of the nacelle, acting as a pusher for the deposit due to its immobility in relation to the notebooks and the movement of the nacelle, contributes to ensuring a reliable and safe deposit of all of said notebooks loaded on the nacelle on a pallet during the erasure of the reception plane of the nacelle from below the notebooks. Said bar being mounted integral with the transport nacelle, the palletizer has great freedom of actuation and therefore positioning relative to the pallet. Thus, the nacelle can be driven to any desired location relative to a pallet or to notebooks already stacked on the pallet since it carries the pusher element for filing and is therefore not dependent on the location of such an element

in the palletizer.

  Consequently, the palletizer according to the invention is not limited as to the positioning of the nacelle which can deposit row by row stacks of notebooks according to 3) specific architectures, in particular, the rows of stacks can be placed apart others in the same layer. Such stacking architectures of notebook stacks are not accessible with

palletizing in layers.

  The speed of the drive means, such as drive belts or drive chains, of the bar is synchronous with the speed of movement of the nacelle and

  direction opposite to the speed of movement of the nacelle so that, when depositing a cartridge or a row of stacks of notebooks, the bar is kept stationary relative to the pallet and to the cartridges or stacks previously deposited on said pallet and in abutment against the notebooks.

  Preferably, the trajectory of the bar defined by the () drive means such as belts or drive chains, has substantially the shape of an L, the vertical branch of the L corresponding to the supply of the bar in the low position facing the notebooks from its high position, while the base of the L corresponds to the maintenance of the abutment of said bar in the low position against the notebooks during movement of the nacelle to erase the reception plane. According to a preferred embodiment of the invention, the entry station is arranged to receive on the one hand a row of stacks of notebooks and on the other hand a cartridge of

stacked notebooks.

  Advantageously, the loading of the nacelle is effected by one face of said nacelle, loading face or input face, while the deposit of the notebooks is carried out

  by its opposite face, unloading face or exit face.

  Such a palletizer thus allows a relatively rapid stacking in so far as the positioning of the nacelle relative to the pallet (first stage of the stack) or relative to the notebooks already stacked on said pallet is direct unlike the devices in which loading and unloading takes place

  make by the same face of a nacelle.

  Preferably, the entry station then consists of a rectangular table formed of longitudinal conveyor belts between which are inserted free rollers rotating about an axis parallel to the conveyor belts, a supply conveyor of stacks of notebooks being positioned in the extension of the conveyor belts of the table at one end of the table while a cartridge inlet conveyor is positioned perpendicularly

to said belts.

  Thus, the path of supply of stacks of notebooks and the path of supply of cartridges leading to the entry station

  extend in perpendicular directions.

  The transport nacelle has a receiving plane whose length and width correspond respectively to the length and to the width of a cartridge of stacked notebooks or of a row of stacks of notebooks, the nacelle extending along the entry station and being substantially the same length. When a cartridge or a row of stacks of notebooks are in position on the entry station, they are engaged on the plane of reception of the nacelle using transfer means. Preferably, these transfer means are constituted by a member exerting a thrust on a cartridge or on a row of stacks of notebooks to cause them to slide from the entry station to the receiving plane of

Platform.

  According to one embodiment, the rollers of the table constituting the entry station can be motorized to be driven in rotation about their axis, their driving in rotation causing the sliding of a cartridge or a row of batteries or packages of notebooks from the entry station to the nacelle, said rolls

  motorized acting as transfer means.

  A device according to the invention therefore makes it possible to palletize either cartridges of notebooks or stacks of notebooks and this, without it being necessary to carry out an at least partial modification of the palletizer, the nacelle as gripping and transport of notebooks accommodating both cartridges and rows of batteries. Pallets of stacks or bundles of notebooks are therefore palletized in the same cycle time as when palletizing de) cartridge at an identical speed. The structure of the palletizer according to the invention is therefore light, relatively simple and easy to implement, occupying a limited volume and which can in particular be used in cooperation with high-speed stacking devices. We will now describe in more detail the invention with reference to the attached drawing in which: FIG. 1 represents a side view of a palletizer 2 () according to an exemplary embodiment of the invention in the loading position of a notebook cartridge; 2 shows a side view of the palletizer of Figure 1 during deposition of the cartridge; Figure 3 shows a side view according to Figure 2 at the end of the deposit; Figures 4a and 4b respectively show a side view and a top view of a palletizer according to the invention for palletizing cartridges of notebooks; Figures 5a and 5b respectively show a side view and a top view of a palletizer according to the invention for palletizing stacks of notebooks; Io Figure 6 shows a side view of a palletizer according to a second embodiment of the invention in the loading position of a notebook cartridge; 7 shows a side view of the palletizer of Figure 6 during deposition of the cartridge; and Figure 8 shows a side view according to Figure 7

at the end of the deposit.

  1) The palletizer according to the invention comprises an input station 1 for the notebooks in the form of cartridges C, a transport nacelle 2 which can be driven in movement from the

  entry station 1 up to a pallet 3.

  The nacelle 2 has a horizontal receiving plane 21 extending between two side walls 22, the receiving plane 21 being adapted to allow the sliding engagement of the cartridge C. 2 () Transfer means of the cartridge C allow the engagement of said cartridge C from the entry station 1 to the transport nacelle 2. These transfer means consist of a pushing member 4 causing the cartridge C to slide from the entry station 1 to on the receiving plane 21 of the nacelle 2, consisting of a

  wide strip stretched between the walls 22, for example.

  The cartridge C is conveyed on a conveyor 5 so as to 3 (, arrive at the entry station 1 by one of its faces

lateral Cl.

  The pushing member 4 is mounted above the cartridge supply path, that is to say above the conveyor 5. It consists of a bar 41 mounted perpendicular to the end of a arm 42, connected at its other end to a translational drive member 43 of the type of a slide,! l driving in translation the arm 42 and the bar 41 in a direction parallel to the direction of the conveyor 5, the arm 42 being pivotally mounted on the translational drive member 43 provided with abutment elements 44 so that a translational drive of the arm 42 away from the input station 1 causes the bar 41 to rise to a inactive position while the drive in translation towards the input station 1 causes the lowering

  of the bar 41 in the pushed position.

  This translational drive member 43 can be actuated pneumatically or hydraulically or by a

belt driven by a motor.

  Ir As can be seen in Figure 1, the bar 41 is driven in translation in the direction of the arrow A towards the entry station 1 to push a cartridge C, positioned in the entry station 1, onto the nacelle 2. For this purpose, the bar 41 extends in the longitudinal direction of the input station 1, has a length substantially equivalent to the length of the input station 1 and extends substantially to a height suitable for allowing its abutment at the rear of, and against a cartridge C (Figure 1) or a row of stacks of notebooks to push it on the nacelle 2. The bar 41 is thus thus positioned in the supply path of the cartridge C. Once the cartridge C engaged on the nacelle 2, the bar 41 is brought back to an inactive position where it is raised so as to disappear from the path for bringing the cartridges C so as not to hinder the arrival of a new cartridge C at the

entry station 1 (figure 2).

  Also, during the drive in translation of the bar 41 in the opposite direction in separation from the input station 1 (arrow B), said bar 41 is raised due to the pivoting of the arm 42 pivotally mounted on the member d in translational drive 43, the latter comprising

  abutment elements 44 against which the arm 42 abuts during the race towards the inactive position (FIG. 2).

  The transfer means will be activated again to

  transfer a new cartridge C from input station 1 to nacelle 2.

  The nacelle 2 further comprises a bar 23 extending <) transversely between the side walls 22 of the nacelle 2 and mounted integral with drive means such as drive belts 24 extending along said side walls 22 around of rollers 25. The trajectory of the bar 23 defined by the drive belts 24 mounted on the rollers 25 has substantially the shape of an L. The drive means can also be drive chains. The bar 23 can be constituted by a

  roller, preferably fixed in rotation.

  2) As can be seen in FIG. 1, the bar 23 is at a high position corresponding to the loading of the cartridge C into the nacelle, then the drive belts 24 are actuated to bring said bar 23 into the low position in abutment against the cartridge C. Thus, as can be seen in FIG. 2, the bar 23 brought into the low position is always in the loading face of the nacelle (vertical bar of the L). To carry out the deposition of the cartridge C when the nacelle 2 has reached the correct position relative to the pallet 3 and to the cartridges C ′ possibly already deposited (FIG. 2), the nacelle 2 is moved in the direction of return. towards the entry station 1 while the bar 23 is held in abutment against the cartridge C by actuating the drive belts 24, the bar 23 moving along the base of the L (FIG. 3) synchronously with the movement of the nacelle 2. The synchronization of the speed of movement of the nacelle and the speed of the means

  bar drive is governed by the controller controlling the operation of said nacelle.

  Thus, this maintenance of the bar 23 in abutment against the cartridge C makes it possible to retain the latter while the reception plane 21 is moved towards the entry station 1. Consequently, the reception plane 21 disappears from below of the cartridge C, which allows it to be deposited on the pallet 3 by the deposition face of the nacelle 2 opposite the loading face. The rod 23 remained stationary relative to the

palette 3.

  Once the cartridge C has been deposited, the nacelle 2 is returned to the entry station to take a new cartridge C, the bar 23 being returned to its upper position

  loading freeing access to the loading face.

  The speed of the drive belts 24 is determined in synchronization with the speed of movement of the nacelle 2 in movement to ensure immobility of the bar 23 relative to the deposition point and thus guarantee safe deposition of the cartridge C. preferably, electric motors are used with frequency variation system allowing

a variation of speeds.

  The means for driving the displacement of the nacelle 2 consist of two vertical carrying mats 6 extending on either side of the nacelle 2 and along which the 3 (nacelle 2 moves vertically, the masts 6 being suspended respectively to a horizontal guide beam 7 along which they can be driven in movement between the entry station 1 and the location of

palette 3.

  Preferably, the input station 1 of the palletizer according to the invention comprises a rectangular table 11 formed of longitudinal conveyor belts 12 between which are rolled free rollers 13 rotating about an axis parallel to said conveyor belts 12. The rollers 13 said to be crossing are lifted slightly above the belts 12 to favor the entry of a cartridge C on the table 1il while they are erased to allow sliding towards the nacelle 2. Preferably, the belt of transport 12 ′, said cartridge brake belt extending from the side of the table 11 adjacent to the nacelle 2, is () of greater width than the other transport belts 12, so as to facilitate the sliding of the notebooks during the transfer of the entry station 1 to the nacelle 2. Indeed, the width of this belt 12 ′ avoids the presence of space (for example between two belts) in which the stacks of notebooks could s 'engage during pushing by the bar 41. As can be seen in Figures 4b and 5b, a supply conveyor 8 of stacks of notebooks P is positioned in the) extension of the conveyor belts 12 of the table 11 while the supply conveyor 5 of the cartridges C extends

  perpendicular to said belts 12.

  Thus, the paths for supplying cartridges C and P batteries

  are perpendicular to each other.

  As can be seen in Figure 4a, the translational drive member 43 of the push bar 41 of the transfer means extends in a direction parallel to the path 3o of supply of the cartridges C. The nacelle 2 s extends parallel to the conveyor belts

12 of the entry station 1.

  Thus, a cartridge C arrives at the entry station 1 by a conveyor 5 of the roller type and slides on the entry station under the effect of the drive of said conveyor 5 and by sliding on the rollers 13 interposed between the

carrying straps 12.

  Once at the entry station 1, the transfer means are actuated which push the cartridge C onto the nacelle 2, the latter taking the cartridge C to deposit it on a

palette 3.

  In the case of stacks P of notebooks (FIG. 5b), the stacks P of notebooks arrive one behind the other by the conveyor 8 and are engaged in the input station 1 using the conveyor belts 12 to form a row of batteries P in the input station 1. The transfer means are then actuated and the bar 41 pushes the whole of the

  row of batteries P on the platform 2.

  Preferably, the supply conveyor 8 of the stacks P of notebooks comprises, before the entry station 1, a cross 81 making it possible to modify the orientation of the stacks P before their entry into the entry station 1. This cross 81 lifts above the plane of the conveyor and is rotated to change the orientation of the stack P resting on it. At the exit from the cross 81 and at the entrance to the entry station 1, a photoelectric cell is set up associated with an encoder fixed on the drive belt drive motor 12 which measures the movement of the conveyor belts 12 to bring a row of batteries to the input station. The driving movement of the conveyor belts 12 is controlled so as to provide free spaces between the packages in a row (see FIG. 5b) or, on the contrary, to leave no free space between the stacks. An automaton therefore controls the drive motor of the belts so that the belts 12 move forward and stop as soon as a pile has entered the table 11 (row of contiguous piles) or else stop after a certain interval after entering the stack so that this interval

  corresponds to a free space between two piles in a row. This makes it possible to stack P stacks of notebooks more securely.

  In particular, the palletizer includes a logic unit of

  control of its actuation which can operate in association with a computer program making it possible, according to the dimensions of the P stacks or C cartridges, to calculate the best possible positioning of the P stacks or C cartridges to ensure a stable and solid stacking on the palette 3.

  The computer program defines the operating scenario of the palletizer (cycle time, speed, movements, etc.), according to the architecture of the desired stack and controls the logic control unit

  allowing the actuation of the palletizer.

  Preferably, the nacelle 2 includes means for automatically measuring the width of the stacks or cartridges in the nacelle 2 and the height of the stacks or cartridges under the nacelle 2.

  Preferably, to measure the width of a stack or of a cartridge, the nacelle comprises two infrared cells mounted opposite each side of the nacelle 2 on the exit side of the notebooks. When the bar 23 pushes a row of batteries or a cartridge to deposit them, the cutting of the beam makes it possible to measure and check the width of the

row or cartridge.

  To measure the height of the batteries or cartridges under the nacelle 2, this comprises two infrared cells mounted opposite each side of the nacelle 2, one on the side of the entrance face of the nacelle 2, the other on the side of the outlet face, generating a beam diagonally under the nacelle 2. The beam thus created, when it is cut, allows detection before removal, which makes it possible to avoid collisions with the cartridges or batteries previously deposited. This is advantageous and avoids damaging the cartridges or batteries already deposited, as is the case with measuring means.

by physical contact.

  In addition, these photoelectric cells generating a diagonal beam under the nacelle 2 make it possible to measure the height of the cartridge or of the batteries previously deposited by counting the number of encoder steps of the vertical movement during which the beam is obscured by the batteries or the

previous cartridge.

  In Figures 6, 7 and 8 is shown a second embodiment of the invention in which the stacking table 11 of the input station 1 consists of conveyor belts 12 and rollers 13 'interposed between the belts 12 and rotatable around their x axis

parallel to said belts 12.

  The rollers 13 'are motorized and are therefore rotatable around their x axis to allow the advancement of a cartridge or a row of batteries towards the nacelle 2, the

  rollers 13 'acting as transfer means.

  Alternatively, these rollers 13 'can be rotated as transfer means on the one hand and, by declutching, be free to rotate to accommodate a

  31 cartridge on the input station 1, on the other hand.

  The reception plane 21 of the nacelle consists of rollers 25 which are free to rotate or motorized around their

  Y axis extending between the side walls 22.
