Description

The present invention relates to a device and a method for transferring at least one palletizable layer to a depositing and / or stacking surface according to the features of the independent claims 1 and 9, respectively.

State of the art

For palletizing entire article layers, the articles normally first pass through a grouping station, in which the transported articles are put together to form palletizable layers. These palletizable layers are then transferred from a delivery station to a loading station. The loading station then deposits these article layers at a desired location. This location is usually formed by a stacking place and a pallet located on it, on which the article layers can be stored. The staging station and the grouping station usually represent a unit and are directly coupled with each other.

The deployment station, like the grouping station, includes a support surface or support plane upon which the articles are grouped and assembled into one layer. The loading station also includes a support plane on which a respective palletizable layer can stand up for transfer to a respective associated pallet. Numerous variants are known to the person skilled in the art for the design of the support plane, such as e.g. Venetian blind heads or similar. In this case, such a palletizing process with a known from the prior art palletizing in such a way that initially articles are assembled by means of a grouping device to a palettierfähigen position and subsequently passed from a supply point or a supply station in the loading station. For this purpose, it may be that the loading station, such as. a arranged on a hoist or robots Jalousiegreiferkopf immediately adjoins the supply location, so that the transfer of the article position can be done in the loading station. In the process, the blind gripper head or the loading station lingers in place until the position has been completely transferred from the supply station to the loading station. If the article position is completely in the loading station, the loading station positions the article layer at a desired delivery location by horizontal and vertical movements, usually on a pallet provided on a stacking station. Thereafter, the same procedure is repeated until the desired number of layers have been deposited on the pallet.

For example, the EP 1 321 396 A1 a palletizer in which the articles are displaced in a disordered manner by a horizontal conveyor in the lateral direction and thereby grouped before they are transferred in complete layers on a lifting device. The lifting device or transfer platform serves as height compensation between the Gruppierstation and the loading station, which stacked the layers and deposits by means of an openable rolling ground on a pallet. The document further discloses that the transfer platform can not pick up and transfer, in a single phase of movement, a number of rows of articles necessary to form a complete article layer. The advantage is seen in the fact that due to the smaller design of the transfer platform and the incomplete lifting of an entire article position less weight must be raised and thus less energy consumption takes place than when lifting the loading station itself.

In order to be able to transfer palettable layers to a pallet, devices according to the EP published application require a great deal of time. In practice devices are desirable, by means of which a transfer of palettierfähigen layers on pallets can be done with high throughput.

The EP 2 103 556 B2 describes a palletizer with a split loading plate, wherein the two part ailerons are diverge for unloading, whereby the desired, to the outer edges precise stacking image is generated. For loading is waived a Wiederzusammenfahren the charging plate. Instead, it is used when loading with divergent Teilladeblechen, whereby the cycle times can be considerably shortened and the palletizing can be increased accordingly.

description

The object of the invention is to further optimize the palletizing of piece goods with regard to speed and precision while at the same time improving the stability of the arrangement of the piece goods of the position to be palletized.

The above object is achieved by an apparatus and a method for transferring at least one palletizable layer to a depositing and / or stacking surface, comprising the features in the independent patent claims. Further advantageous embodiments are described by the subclaims.

To achieve the above object, the invention proposes a device for transferring at least one palletizable layer to a Storage and / or stacking surface, wherein this stacking surface may be formed in particular by a pallet. Furthermore, the stacking surface may be formed by a palletizable layer arranged on top of a pallet. The device proposed by the present invention comprises a provision position for at least one palletizable layer, wherein each such layer is formed by a plurality of piece goods, which are arranged within a defined space. In addition, the device comprises a loading station, which is formed by a first loading unit and a second loading unit, wherein the first loading unit is designed to receive a complete palettierfähigen position.

The palletizable layer provided in the provisioning position can be completely transferred to and / or moved in an overrunning direction to the first loading unit. It is further provided that the palletizable layer received on the first loading unit can be partially transferred and / or moved from the first loading unit to the second loading unit, so that the palletizable layer completely accommodated by the first loading unit partially transfers to the second loading unit in the course of the stacking process and is borne jointly by the first loading unit and the second loading unit. In particular, in a closed position of the loading station, the first and second loading units form a loading surface for the layer.

Optionally, the loading station in the staging position may be assigned a suitable ply preparation and / or ply deployment module, i. upstream in the transport direction of the layers formed from the piece goods to be. About this module or these modules are successively presented palettierfähigen and each having a plurality or plurality of cargo having position and passed to the loading station. The provision can be designed as part of a grouping station or as a grouping table. In addition, the provision may usefully form a horizontal footprint for a respective palletizable layer.

For depositing the complete palletizable layer on the storage and / or stacking surface and / or on an upper side of a previously stored there and already palletized layer, the first loading unit and the second loading unit can be distanced from each other or can be moved apart, with a thereby formable minimum distance between the first loading unit and the second loading unit corresponds to at least one width of the palletizable layer previously located thereon.

The sliding over of the complete palletizable layer from the provisioning position to the first loading unit takes place by means of a first movable pushing element. The first loading unit is assigned to stabilize the position during this sliding over and / or when moving the layer on the first loading unit, a first movable contact element. Furthermore, the first loading unit is associated with a second movable thrust element for at least partially sliding over the layer from the first loading unit to the second loading unit. In this case, the position is stabilized by a second movable contact element of the second charging unit.

The first movable pushing element is preferably associated with the layer preparation and / or layer providing module and can be pivoted upwards, for example. The second thrust element can, in particular, cover a movement space parallel to the support surface of the provisioning position, which roughly corresponds to the width of the layer or the length of the provision position in the direction of transfer of the layers. According to one embodiment of the invention, pieces of goods are assembled and arranged according to a predetermined layer scheme in a grouping module, wherein gaps may still be formed between the piece goods of the prepared within the Gruppiermoduls layer, which are undesirable in the palettierfähigen position. The piece goods are subsequently pushed together, for example, within at least one Vorgruppierungsmoduls to a compact position in a staging position. The first push element is assigned, for example, to the pre-grouping. When transferring the prepared position from the grouping module into the pre-grouping module, the first push element is located in a particularly upwardly pivoted position. Once all the parcels of the prepared layer are within the pre-grouping module, the first pusher is swung down so that it rests against the rear sides of the parcels forming the rear longitudinal side of the ply. By means of a movement of the first thrust element in the overrunning direction, the compact layer formed within the provisioning position of the pre-grouping module is pushed onto the first loading unit. The first thrust element can this not only the sliding over the layer on the first charging unit this, it can also play a role in the production of the compact layer. In particular, the compact layer can also be formed only when the layer is pushed over onto the first loading unit.

It is further provided that the first loading unit, a first movable contact element for stabilizing an anticipatory in Überubrichtung, transversely to the Überubrichtung extending longitudinal side of the layer when transferring the layer from the provision position to the first loading unit and / or associated with a movement of the layer on the first loading unit. The first abutment element can in particular cover a movement space parallel to the support surface of the first loading unit, which also approximately corresponds to the width of the layer or the length of the first loading unit in the direction of the shifts of the layers. The first contact element associated with the first loading unit forms in particular a counter-holder to the first push element of the upstream layer preparation and / or layer supply module.

The first loading unit and the second loading unit are preferably each associated with further movable contact beams for stabilizing and / or partially sliding over the layer from the first to the second loading unit. In particular, the first loading unit is associated with a second movable thrust element and the second loading unit with a second movable abutment element.

According to one embodiment of the invention, the second thrust element and the second abutment element can be mechanically coupled to one another in such a way that upon movement of one of the abutment beams in one direction of movement, the respectively other abutment beam moves in an opposite direction of movement. The two contact beams can be driven by a single drive. Alternatively, each contact beam can be driven individually, with the movements of the contact beams are electronically coupled.

According to an alternative embodiment of the device, the two contact beams are driven independently of each other and in particular independently controllable. In this case, it can be provided that the contact beams acting on both sides of the deposited and / or settled layer are non-synchronous and / or independently movable at least in phases, in particular that the two contact beams move at least at times simultaneously in directions of movement parallel to the transport direction of the transfer movement of the layer to the first loading unit can be. With respect to a device with a second attachment element of the second loading unit that is designed to be movable independently of the second pushing element of the first loading unit, reference is made to the application with the file reference DE 10 2017 208 753.6 Reference is made, the content of which is hereby incorporated into this application and the contents of which the reader of the present application is deemed to be known.

The loading station of the device according to the invention for transferring at least one palletizable layer to the depositing and / or stacking surface or to the waiting pallet comprises a divided loading plate, which is formed in particular from the mentioned first loading unit as well as the second loading unit also mentioned. The first loading unit designed with regard to its arrangement, loading capacity and dimensioning for receiving a complete palletizable layer is also referred to below as the full-layer loading plate. In contrast, the first loading unit downstream in the transport direction second loading unit is smaller or comprises a smaller contact surface and is therefore formed only for partial reception of a complete palettierfähigen position. In particular, it can be provided that the second loading unit in each case receives only half a palletizable layer; It is therefore also referred to below as a half-layer loading plate. The first loading unit can form a support plane on which, for example, a full palletizable layer can be accommodated when the loading plate is open. Further, a fully received palettable layer in the closed position of the loading plate is partially continued from the first loading unit to the second loading unit, so that the palettable layer in this process phase, which precedes the storage operation on the pallet, carried jointly by the first loading unit and the second loading unit becomes.

The loading station may, for example, be designed to be height-adjustable via a lifting column arranged on a lifting column. Thus, the height of the first and second loading unit can be easily adapted to the height of the pallet to be loaded, since this increases with each position arranged on the pallet. It makes sense that the two loading units are each adjusted in height synchronously, since a non-synchronous lifting operation with a location thereon is not feasible feasible.

One of these at least two said and the Beladestation associated conditioning beam can serve as a second thrust element, which is in particular provided for partially overmoving the palletizable layer completely received by the first loading unit from the first loading unit to the second loading unit. The second thrust element is spatially associated with the first loading unit and can in particular cover a movement space parallel to the bearing surface of the first loading unit, which corresponds approximately to the width of the layer or the length of the first loading unit in the transport direction of the layers. If, in this context, there is also some reference to a horizontal displaceability, then this means that parallel to the vertically adjustable, but also displaceable in the horizontal direction first loading unit displaceability to the support surface of the first charging unit. Furthermore, it can be provided that the second thrust element via a hinge o. Like. Swung away from the first loading unit or, for example. Over a short stroke can be moved upwards. This is in particular necessary in order to enable the transfer of another palletizable layer from the layer preparation and / or layer supply module, so that in this case the new layer can be pushed onto the first loading unit under the upwardly pivoted or upwardly displaced second pushing element.

In the device can also be provided that at least one can be applied to the vorereilende in the overthrusting longitudinal edge of the situation and moving toward the second loading unit position leading or at least temporarily or phased there fitting second contact element by at least one single or multi-part position stop , This one- or multi-part layer stop can stabilize the layer during its sliding over in the direction of the second loading unit and possibly prevent individual articles of the layer from tipping over, especially in the case of rapid overthrusting operations with the associated abrupt acceleration and deceleration. The voltage applied to one side of the situation second contact element and the voltage applied to the opposite side of the situation second thrust element can fix the position together when the loading units are moved apart for depositing the layer.

According to an embodiment of the invention, the first abutment element is designed to be movable relative to the first loading unit, in particular to be relatively movable relative to an upper side of the first loading unit, which forms a bearing surface, contact surface or support plane for the respective position. Also in this case, a parallel displaceability to the bearing surface of the first charging unit is desired. In a first method step, the layer is transferred at least partly from the provision position to the first loading unit in a first method step and at least partially from the first loading unit to the second loading unit in a second method step in a transfer direction. In this case, provision is made in particular for the first abutment element in the first method step, that is to say, during the transfer of the layer from the ready position to the first loading unit and / or during a movement of the layer on the first loading unit in the overrunning direction to extend in the direction of the overrunning direction Longitudinal side of the situation associated with adjacent and can be moved together with the location in Überubrichtung. In contrast, it is preferably provided that the first contact element is removed before the partial sliding over of the layer on the second loading unit from the front longitudinal edge of the layer to allow sliding over the layer to the second loading unit.

According to one embodiment, a separate drive is assigned to the first contact element, so that it can be controlled individually and independently of further contact or push elements of the device.

The first abutment element is at least partially designed to be movable on the upper side of the first loading unit. In particular, the first abutment element can be moved transversely to the overthrusting direction on the upper side of the first loading unit. In this case, the first contact element can go far as far as extending to the overthrusting, the second loading unit facing side surface of the first loading unit to be moved with the loading area in direct contact or immediately adjacent to a transversely extending to the extension, the first charging unit side facing surface the second charging unit is arranged.

According to one embodiment of the invention, the first abutment element is in a closed arrangement of the first and second loading units, i. when the loading plate is closed, in which the two loading units form a common loading surface for the layer, can be integrated into the first loading unit so that an undisturbed overrun of a part of the layer, in particular one half of the layer, can take place from the first to the second loading unit. For example, the first contact element is designed to be displaceable and foldable within the first loading unit. The first contact element can preferably be displaced at least in regions on the upper side of the first loading unit in the overrunning direction or counter to the overthrusting direction. In addition, the first contact element can be sunk within a specially designed region of the first loading unit within the same, preferably forming a surface of the first contact element and a surface of the top of the first charging unit at least substantially one plane. Thus, at least during the sliding over of the layer from the first to the second loading unit, a planar upper side of the first loading unit is formed, so that there is no risk of tipping and / or falling over of individual piece goods, sticking or the like. consists.

For example, it may be provided that the first abutment element is arranged on at least one circumferentially arranged within the first loading unit arranged parallel to the Überubrichtung transport chain, wherein in the region of the transversely extending to the Überubrichtung, the first loading unit facing side surface of the second loading unit, a deflection of the transport chain is formed , In the deflection region, the upper side of the first loading unit is designed as a receptacle for the first contact element. Is this located? first contact element in the deflection, then it is received by folding in such a way in the recording that the first contact element formed together with the top of the first charging unit, the above-described plane footprint.

According to an alternative embodiment, the first abutment element is movably arranged on a lifting column or a frame element of the loading station. Preferably, the first contact element should be arranged on the lifting column, on which the first and second loading unit are arranged to be movable. If this, for example, for reasons of space or similar is not possible, for example, a second lifting column opposite to the first lifting column may be formed, for example on the lifting carriage of the first lifting column opposite parallel side of the first and second loading unit. The first abutment element is designed in particular vertically movable and / or horizontally movable and / or pivotable. Preferably, it is vertically movable and / or horizontally movable and / or pivotally mounted on the lifting column or the frame member, so that it can be moved in a horizontal plane on the first loading unit together with the position in the overthrust and on the other hand, for example, by a pivoting movement can be moved away above to allow the subsequent partial transfer of the position to the second loading unit.

The first abutment element supports the position when sliding over the supply position, which is formed for example by a Vorgruppierungsmodul, while the second abutment member supports the position when partially transferred to the second loading unit of the shared loading plate of the loading station. The situation is now supported not only when the loading plate is closed, thereby preventing falling over of individual piece goods of the situation. By the first contact element now also supporting the situation with open loading plate is possible. With the help of the two contact elements can now largely uniform drifting of the situation even at high layer performance and rapid Überububgängen with the associated abrupt acceleration and deceleration, i. be prevented at a high throughput per hour, in particular at a throughput of 450 or more palletized layers per hour. As a result, the throughput can be further increased.

The invention further relates to a method for transferring at least one palletizable layer to a storage and / or stacking surface, which may be formed in particular by a pallet. The method comprises at least the following steps in the specified or a different order: A palletable layer of a plurality of piece goods arranged within a defined space is provided. This is completely transferred or transferred to a first loading unit, which forms part of a loading station. Subsequently, the first loading unit is moved together with the palletizable layer received thereon in the direction of a second loading unit. The second loading unit also forms part of the loading station. Subsequently or partially simultaneously, the palletizable layer received by the first loading unit is moved in the direction of the second loading unit. In particular, the second and first loading units are moved towards each other until they substantially abut one another and form a closed loading plate. Once the closed loading plate is formed, the palletizable layer can be partially pushed onto the second loading unit, so that the first and the second loading unit carry the layer together.

For depositing the complete palettierfähigen position on the storage and / or stacking surface and / or on an upper side of a previously stored there and already palletized layer, the first charging unit and the second charging unit are spaced from each other, wherein the distance between the first charging unit and the second loading unit corresponds to at least one width of the palletizable layer previously located on it. When transferring the provided palletizable layer from the provisioning position to the first loading unit, a first abutment element engages, at least temporarily, on a longitudinal side of the layer that protrudes in the overrunning direction and extends transversely to the overthrusting direction. For example, the first contact element lays against the leading side surfaces of the piece goods forming the longitudinal side of the layers and thus supports and / or stabilizes the leading longitudinal side of the layer when the palletizable layer is pushed over by a first movable push element.

During the moving apart of the first loading unit and the second loading unit for the purpose of settling the palettierfähigen position this is at both longitudinal sides, which are transverse to the transport direction when transferring the situation on the first and / or second loading unit, by a second movable contact element and a second movable pusher supported and / or stabilized on both sides.

Therefore, if at one point at the Description or in the claim definitions for the device according to the invention of certain aspects and / or relationships and / or effects is mentioned, this applies equally to the inventive method.

Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments are merely examples of how the device or method of the invention may be configured and are not an exhaustive limitation.

1 shows a perspective view of a first embodiment of a loading station 1 , The loading station 1 is in particular part of a palletizer 10 which further comprises a pallet loading and unloading device 2 and, for example, additionally with an interlayer feeder 3 can be equipped. The pallet 6 will be in pallet feed direction 50 in the loading station 1 introduced and in pallet removal direction 51 from the loading station 1 away. The pallet feed direction 50 and the pallet removal direction 51 are preferably rectilinear in an alignment and transverse to the Überubrichtung ÜR the palletizable layer or container layer 7 (see 2 to 19 ) within the loading station 1 educated.

The loading station 1 is also a layer preparation and provision module (not shown, cf. 2 to 19 ), via which a palletizable and a variety of piece goods having packaged layer 7 (see 2 to 19 ) can be presented. The provision can be designed as part of a grouping station or as a grouping table. Further, the provision may be a horizontal footprint for a respective palletizable layer 7 form.

The loading station 1 includes a first charging unit 20 and a second loading unit 22 , The first loading unit 20 is designed to receive a complete palettierfähigen position and is hereinafter also as a full-layer loading plate 21 designated. In contrast, the second charging unit 22 designed only for partial reception of a complete palettierfähigen position. In particular, it is provided that the second charging unit 22 each takes only a half palettierfähige position; the second loading unit 22 is therefore hereinafter also referred to as a half-layer loading plate 23 designated. The first loading unit 20 can be a substantially horizontal support plane 25 form, on which a complete palettierfähige position can be recorded. Further, a fully received palletizing layer is partly from the first loading unit 20 to the second charging unit 22 weiterführbar, so that the palletizable layer together from the first loading unit 20 and the second loading unit 22 will be carried. This is especially related to the 2 to 18 shown in detail and described in more detail below.

The loading station 1 includes one on a lifting column 5 arranged lifting 4 over which the first and second charging unit 20 . 22 height adjustable on the lifting column 5 are arranged. Thus, the height of the first and second loading unit 20 . 22 simply to the height of the pallet to be loaded 6 be adjusted as this height with everyone on the pallet 6 arranged palettierfähigen position increases accordingly. Preferably, the lifting is 4 via a linear guide on the lifting column 5 movably arranged, in particular, maintenance-free plastic rollers or other suitable linear bearings can be used.

The loading station 1 comprises a push element in the form of a push beam 30 in particular, which serves to completely from the first loading unit 20 taken palettierfähige position partially from the first charging unit 20 on the second loading unit 22 via push. The as a push bar 30 designated slide / as a push bar 30 designated pushing element is the first loading unit 20 assigned and can in particular between one of the second charging unit 22 facing first edge 26 the first charging unit 20 and a second edge disposed parallel thereto 27 the first charging unit 20 be moved in a horizontal direction. Furthermore, it can be provided that the push bar 30 over a swivel joint 31 or a lifting device or the like moved up and / or from the first charging unit 20 can be swung away. This is particularly necessary to allow the transfer of another palletizable layer from the ply preparation and supply module (not shown), so that this ply is under the upwardly pivoted or upwardly pivoted pusher bar 30 can dive through.

Furthermore, the loading station includes 1 an investment element 35 , in particular a so-called position stop 36 , which is parallel to the push bar 30 is arranged. As a rule, the push bar is 30 the first charging unit 20 and the layer stop 36 the second loading unit 22 assigned. The layer stop 36 can move in the direction of the push bar 30 or from the push bar 30 be moved away. According to one embodiment of the invention are layer stop 36 and push bar 30 mechanically coupled together, in particular such that the movement of the push beam 30 in a first direction of movement, an oppositely directed movement of the layer stop 36 causes. According to an alternative embodiment, the layer stop 36 be assigned a separate drive, so that the push bar 30 and the layer stop 36 can be moved individually and independently of each other. In this case, the individually controllable position stop 36 prematurely at the push bar 30 attack opposite side of a palettierfähigen layer and thus the palletizable layer at least partially during the Überubprozesses from the first to the second loading unit 20 . 22 support. In particular, the push bar pushes 30 the container layer to be palletized 7 in the direction of the second charging unit 22 while the posture stop 36 at least temporarily or in phases to a leading edge 70 the packaging situation 7 is put on and together with the container layer 7 , in particular this leading, towards the second charging unit 22 emotional. Due to the individually controllable layer stop 36 is when pushing the container layer 7 towards the second loading unit 22 the container situation 7 stabilized and it will be particular individual items or cargo of the package 7 prevented from tipping over. It may thus be preferred that the layer stop 36 and the push bar 30 during partial transfer of the package layer 7 from the first charging unit 20 to the second loading unit 20 at least phased synchronously in the same direction to each other.

The first loading unit 20 and the second loading unit 22 can be mechanically coupled to each other, so that the first charging unit 20 and the second loading unit 22 can not be moved relative to each other in the vertical direction. Furthermore, the first charging unit 20 and the second loading unit 22 be mechanically coupled to each other so that they can each perform a directed in a horizontal plane opposite movement, in particular a movement towards or away from each other.

The movement of the first and second load unit, the push beam 30 and optionally further components of the loading station and / or the palletizing device 10 in particular via at least one control device 9 controlled and controlled. This is preferably in a control cabinet 11 arranged.

The lifting column 5 with the lifting carriage 4 and the other functional components of the loading station 1 is preferably on a floor frame 12 arranged and fixed, that of the loading station 1 gives the necessary stability. For example, it is provided that the pallet supply and removal device 2 above the floor frame 12 is arranged extending, causing a tilting of the loading station 1 is additionally prevented. The lifting column 5 is about vertical and horizontal spacer frame elements 13 . 14 such on the floor frame 12 arranged that the pallet loading and unloading facility 2 below the lifting column 5 can be arranged extending therethrough. Furthermore, as a counterweight to the lifting column 5 and stabilization of the loading station 1 a supporting frame element 16 and a cross connection 17 intended. On the supporting frame element 16 and / or the cross connection 17 For example, the liner insert 3 be arranged.

The described and in two loading units 20 . 22 subdivided loading plate of the loading station 1 allows services of up to 450 palletized layers per hour. Due to the two-part loading plate, it is also possible to palletise layer patterns with gaps between the piece goods.

2 to 12 show schematically a side view of a first functional sequence when loading a pallet 6 with bundle layers 7 within a loading station 1 ,

As in 2 can be clearly seen, there are already four bundle layers 7 on the pallet to be loaded 6 , The mechanical with the lifting carriage (see 1 ) and mechanically coupled first and second loading units 20 . 22 are moved to the level of the ply preparation and deployment module by vertical movement of the lift carriage on the lift column 40 , for example a pre-grouping 41 , brought and a suitably prepared container layer 7 - 1 is done with the help of a layer preparation and deployment module 4 assigned thrust element in the form of a sliding beam 42 on the first loading unit 20 or full-layer loading plate 21 pushed over ( 3 ). The so within the loading station 1 arranged bundle layer 7 - 1 can now be at the top of the range 6 arranged bundle layer 7 be pushed over.

The first charging unit 20 is also a push bar 30 assigned and the second loading unit 22 is a layer slider 36 assigned. It is preferably provided that the layer slide 36 and the push bar 30 also on the lifting carriage 4 are suspended and stored and thus together with the first and second loading unit 20 . 22 vertically movable at the lifting column 5 are arranged. In the embodiment shown here are the ply slide 36 and the push bar 30 each driven individually and designed individually controllable, as in the application with the file number DE 10 2017 208 753.6 has been described, the contents of which are hereby incorporated into this application and the contents of which the reader of the present application is deemed to be known. The additionally described below the first charging unit associated, independently driven contact element 60 but can also be used in loading stations where the movement of the push beam 30 and the ply slide 36 are coupled, in particular such that a respective opposite movement takes place.

For pushing the container layer 7 - 1 from the sheet preparation and delivery module 40 on the first loading unit 20 or full-layer loading plate 21 is the push bar 30 in an upwardly pivoted, open position ( 2 . 3 ). The first charging unit 20 is an additional investment element 60 assigned, in particular relative to the first charging unit 20 is designed to be movable. This additional investment element is already at the first crossing of the package layer 7 - 1 from the lay preparation and deployment module 40 on the first loading unit 20 at the in Überubrichtung ÜR front edge 8th the packaging situation 7 - 1 created and stabilized thus the container layer 7 - 1 while sliding over the ply preparation and deployment module 40 on the first loading unit 20 (see 2 and 3 ).

After the package situation 7 - 1 completely on the full-layer loading plate 21 has been transferred, is the push bar 30 pivoted down and lays down to the rear edge 80 the packaging situation 7 - 1 at ( 4 ). Also when further sliding over the container layer 7 - 1 on the whole-layer loading plate 21 by means of the first charging unit 20 associated sliding beam 30 , stabilizes the additional contact element 60 the container situation 7 - 1 and thus prevents in particular falling over of individual piece goods of the pack layer 7 - 1 ,

After the package situation 7 - 1 completely on the full-layer loading plate 21 is arranged, the first charging unit 20 with the container layer 7 - 1 and the second loading unit 22 over the lifting carriage 4 in a delivery height immediately above the top of the pallet 6 arranged bundle layer 7 raised ( 4 ). That of the second charging unit 22 assigned investment element 35 gets in as close as possible to the first charging unit 20 arranged, in particular approximately in the middle of the delivery position ( 7 ). The first loading unit 20 or full-layer loading plate 21 and the second loading unit 22 or half-layer loading plate 23 are brought together synchronously, ie they move synchronously to the middle of the delivery position ( 7 ).

At the latest after the first and the second loading unit 20 . 22 are fully merged ( 7 ), is a stabilization of the container layer 7 - 1 through the additional contact element 60 disturbing. In particular, the additional investment element 60 the at least partially sliding over the container layer 7 - 1 from the whole-layer loading plate 21 on the half-layer loading plate 23 prevent. For this reason, the contact element must 60 before pushing the container layer 7 - 1 on the half-layer loading plate 23 from the front edge 8th the packaging situation 7 - 1 be removed. It is envisaged that the abutment element 60 within the full-layer loading plate 21 is movably guided and also within the whole-layer loading plate 21 is formed submerged, in particular in the area adjacent to the first edge 26 (see 1 ) of the full-layer loading plate 21 who is in a closed working position Pg the loading station 1 directly to the half-layer loading plate 23 adjoins ( 7 ).

Once the first and the second charging unit 20 . 22 are merged and form a common bearing surface, the push bar 30 continue in Überubrichtung ÜR in the direction of the second charging unit 22 moves and pushes the container layer 7 - 1 partly on the second loading unit 22 above. At the same time, the package layer hits 7 - 1 to the position stop 36 on, which then also in the same Überubrichtung ÜR like the packaging situation 7 - 1 and the push bar 30 with the container layer 7 - 1 is moved and thus a divergence of the package layer 7 - 1 prevents ( 8th . 9 ). Preferably, the package layer 7 - 1 half to the second loading unit 22 pushed over, leaving the other half on the first loading unit 20 remains. The packaging situation 7 - 1 is now from both loading units 20 . 22 worn together. After the package situation 7 - 1 in the delivery position according to 9 is arranged, open the first and second loading unit 20 . 22 in which they are synchronously moved apart horizontally. The loading units 20 . 22 are moved apart at least until a minimum distance is formed, the at least one width of the package layer 7 - 1 in Überubrichtung ÜR equivalent. The loading station is thus again in an open working position po , The moving apart of the first and second loading unit 20 . 22 serves to settle the container layer 7 - 1 on the top, on the pallet 6 arranged bundle layer 7 , This left the push bar 30 and the layer stop 36 in their position and stabilize the container layer 7 - 4 thus continue ( 10 ) until this is completely on the topmost position 7 on the pallet 6 has been discontinued.

Subsequently, the first and second loading unit 20 . 22 again to the level of the layer preparation and deployment module 40 brought ( 11 ) and now with five bundle layers 7 . 7 - 1 loaded pallet 6 can via the pallet feeding and transporting device 2 now in pallet removal direction 51 (see 1 ) from the loading station 1 exit. At the same time, a new pallet can be delivered via the pallet loading and unloading device 2 in pallet feed direction 50 be fed and a new container layer 7 - 2 with open push bar 30 on the first loading unit 20 be pushed over. Alternatively, another could be a packaged layer 7 - 2 in accordance with the process steps described above on the now upper drum layer 7 - 1 the pallet 6 to be ordered.

13 to 18 schematically show the first functional sequence when loading a pallet 6 with bundle layers 7 within a loading station 1 from above. It is essentially based on the description of the 2 to 12 directed. In particular, show 13 and 14 the loading station 1 in an open working position po , where the prepared container layer 7 - 1 by means of the layer preparation and delivery module 40 associated sliding beam 42 and supported by the additional abutment element 60 from the ply preparation and deployment module 40 on the full-layer loading plate 21 is pushed over. Show against it 15 and 16 the loading station 1 in a closed working position Pg , where the prepared container layer 7 - 1 by means of the first charging unit 20 associated sliding beam 30 at least partially on the semi-layer loading plate 23 is pushed over, and thereby by the second loading unit 22 assigned investment element 35 or the layer stop 36 is supported. The additional, the first charging unit 20 assigned investment element 60 located at the in the 14 to 17 illustrated process steps each sunk within the full-layer loading plate 21 , Preferably, the side surface of the contact element form 60 according to 13 the front edge 8th the contacted and the top of the full-layer loading plate 21 in this case a flat surface.

The synchronous opening by the movement of the full-layer loading plate 21 against the overthrusting direction ÜR and the movement of the half-layer loading plate 23 in Überubrichtung ÜR leads to the storage of the container layer 7 - 1 on the pallet 6 or on a topmost layer of already on the pallet 6 arranged bundle layers. 18 This corresponds essentially to the presentation of the 11 ie, the first and second charging units 20 . 22 were again at the level of the lay preparation and deployment module 40 brought, so another, already through the layer preparation and deployment module 40 Prepared and provided container layer 7 - 2 with open push bar 30 on the first loading unit 20 can be pushed over us now topmost layer of packaging 7 - 1 on the pallet 6 can be arranged.

19 shows a further embodiment of a loading station 1 from above. It is essentially based on the description of the 2 to 18 directed. The difference from the first embodiment according to 2 to 12 and 13 to 18 is that the additional investment element 60 not within the whole-layer loading plate 21 is designed to be retractable, but that the additional contact element 60 also on a lifting column 45 is arranged. As a rule, an arrangement of the additional contact element on the lifting column 5 at the first and second loading unit 20 . 22 and further machine components are arranged, not possible for reasons of space. Therefore, an arrangement on another lifting column 45 or other frame elements of the loading station 1 , For example, on a supporting frame element 16 according to 1 o .ä., necessary. The investment element 60 can over the lifting column 45 be designed vertically movable. The investment element 60 However, it can also be pivoted on the lifting column 45 or another suitable frame element of the loading station 1 be arranged. In addition, the investment element 60 about one's own Drive horizontally movable to make it to the front edge 8th the respective container layer 7 . 7 - 1 can be moved to support the same.

The invention has been described with reference to a preferred embodiment. However, it will be apparent to those skilled in the art that modifications or changes may be made to the invention without departing from the scope of the following claims.
