The palletizing head (1) has a support level (2) for each layer of individual items to be picked up and transferred from a receiving station to a destination. This support level (2) can be removed from under the layer of individual items at the destination. The placement direction (A) of the layer of individual items at the destination is oriented approximately perpendicular to a loading direction (B) at the receiving station. The layer of individual items can be stabilized and positioned within the palletizing head (1) both when picked up at the receiving station and when placed at the destination, in coordination with a positioning movement of the palletizing head (1) between the receiving station and the destination. The process involves picking up individual loads at a receiving station and transferring them onto a support level (2) of the palletizing head (1).

The discharge direction (A) of the loads at the destination is approximately perpendicular to the loading direction (B) of the loads at the receiving station. The loads are initially positioned within and relative to the palletizing head (1). As the palletizing head (1) moves to the destination, the loads are further advanced on the support level (2) in the loading direction (B). Upon reaching the destination, the support level (2) is removed from beneath the loads to be deposited.

Description

[0001] The present invention relates to a palletizing head with a support surface for each layer of goods to be picked up and transferred from a receiving station to a destination, and to a method for palletizing layers of goods using such a palletizing head. In particular, the invention relates to layer positioning with a counter-holder.

[0002] One goal of automated handling of individual items, such as single objects, packages of multiple objects, groups of multiple objects, or combinations thereof, is a high throughput. This can be described by the cycle time, which determines how many items can be handled in the shortest possible time. The shorter the cycle time, the higher the throughput and, consequently, the better the utilization of the machines, systems, and equipment used for this purpose.

[0003] The cycle time can be intuitively described by its inverse: the ratio of the number of units to the time it takes to handle that number of units. The inverse of the cycle time can also be called throughput. Often, the terms throughput and cycle time are used interchangeably, for example, when referring to achieving the highest possible cycle time.

[0004] Automated handling of general cargo typically involves palletizing in accordance with shipping regulations. Palletizing is achieved by creating layers of general cargo, one after the other, and then stacking them on top of each other onto pallets. These layers are usually palletizable, consisting of several individual items arranged according to the dimensions of a pallet, such as beverage containers. Stacking is accomplished by placing one layer of general cargo after another onto the pallet until a predetermined number of layers is reached. The full pallet is then transported away and replaced with an empty pallet, on which the stacking process begins again.

[0005] Such palletizing inevitably takes place in batches, with the formation and placement of the individual goods layers one after the other through two different parts of the system.

[0006] The formation of individual load layers is typically carried out by a layer formation unit, also known as a grouping station, for example, at the end of a filling and / or packaging line. Palletizing, i.e., placing the individual load layers at a stacking point, also known as a loading point, is performed by a palletizing station, also known as a loading unit. Its essential component, responsible for picking up the formed layer of individual loads and placing them at the stacking point, is a palletizing head.

[0007] To pick up a layer of individual items, it is transferred from the grouping station to the palletizing head. The layer of items is positioned in a delivery or placement position on a support level within the palletizing head. During this process, the palletizing head is located at a receiving station. The palletizing head then transfers the layer of items to the stacking station. Movement of the palletizing head in the X or Y direction, either longitudinally or laterally, relative to the transfer of the layer of items at the receiving station, is only possible once the layer of items is in the delivery position, as otherwise the order of items could shift. Upon arrival at the destination, the support level is removed to allow the layer of items in the palletizing head to be placed beneath the layer of items in the delivery position.

[0008] The individual items can be positioned, for example, by means of a slider into a delivery or placement position on a support level in the palletizing head.

[0009] The pusher can include a push beam that slides the layer of goods over and positions it in the palletizing head.

[0010] The disadvantage of this is that the transfer of the individual load layers from the grouping station to the palletizing head is only possible at low speed, as otherwise the individual load layer would overshoot the delivery position due to its inertia.

[0011] EP 2 610 197 B1 discloses a method for transferring the load without a drive. The kinetic energy provided by a conveyor transporting the load layers to the receiving station is used to propel the load layer, through its inertia, to the discharge position on a support surface formed by freely rotating rollers, upon impact with a stopper strip.

[0012] The disadvantage of this is that the transfer of the individual load layers from the grouping station to the palletizing head is only possible at relatively low speeds, as the load layer would otherwise partially topple over upon sudden impact against the stopper bar at high speed.

[0013] From EP 2 639 165 B2 and EP 2 825 488 B1 it is known that the slide not only includes a push beam that carries out the sliding, but also a support beam that moves together with it and advances at a short distance during the sliding of the load layer.

[0014] The disadvantage of this method is the resulting time loss during the transfer process, as the system must wait for the complete positioning of the individual items in the palletizing head before it can be moved. Furthermore, a high drive power is required for the pusher to position the items in order to keep these time losses manageable.

[0015] To achieve a high throughput of individual items, only very short timeframes are available for forming the layers of items, picking them up from the palletizing head, and placing them down. This requires high speeds for the intervening movements, accompanied by high accelerations and the corresponding high drive power of both the palletizing head and the pusher. As a result, the relevant components of the palletizing head and the pusher experience high wear.

[0016] One object of the invention is to create a palletizing head and a method for palletizing layers of unit loads using such a palletizing head, which have a high unit load throughput, preferably with simultaneously reduced specific wear, corresponding to the actual wear occurring in relation to the unit load throughput.

[0017] The above problem is solved by a palletizing head and a method for palletizing layers of individual items using such a palletizing head, each comprising the features of the independent apparatus and method claims, respectively. Further advantageous embodiments are described by the dependent claims.

[0018] A first aspect of the invention relates to a palletizing head which has a support surface for each layer of goods to be picked up and transferred from a receiving station to a destination. The support surface is removable from beneath the layer of goods located in the palletizing head at the destination for the purpose of depositing the layer of goods. The palletizing head is movable between the receiving station and the destination.

[0019] The direction in which the general cargo is laid down at the destination can be oriented approximately perpendicular to the direction in which the general cargo is loaded at the receiving point.

[0020] The palletizing head is characterized by the fact that the position of the individual items during their pickup at the receiving point and during their placement at the destination can be stabilized and positioned within the palletizing head in coordination with a positioning movement of the palletizing head between the receiving point and the destination.

[0021] A second aspect of the invention relates to a method for palletizing layers of individual items using a palletizing head. In this method, the layers of individual items are picked up at a receiving station and transferred onto a support surface of the palletizing head in order to be placed at a destination location by means of the palletizing head. Placement is effected by removing the support surface beneath the layer of individual items located in the palletizing head at the destination location.

[0022] It is advantageous for the general cargo to be placed in a direction approximately perpendicular to the loading direction of the general cargo at the receiving point when it is placed at the destination.

[0023] The process involves positioning the individual items within the palletizing head and relative to it during the transfer process. Subsequently, as the palletizing head moves to its destination, the individual items are advanced along the support plane in the loading direction. Upon reaching the destination, the support plane is removed from beneath the item to be placed.

[0024] The forward movement of the individual items in the loading direction advantageously refers to the direction of movement of the individual items within the palletizing head. This forward movement occurs during the transfer of the palletizing head to its destination, for example, at the beginning and / or end of the transfer. Particularly preferably, the forward movement is achieved by utilizing the inertia of the individual items during the acceleration and / or deceleration of the palletizing head during the transfer.

[0025] Advantages arise, for example, because the palletizing head, with its movement from the receiving point to the destination (referred to as the transfer movement), does not have to wait until the individual items reach their delivery position during the transfer.

[0026] The stabilization and positioning within the palletizing head allow the transfer movement to begin as soon as the goods are positioned on the support surface. The stabilization and positioning of the goods within the palletizing head preferably occurs independently of the sliding action.

[0027] The stabilization and positioning of the individual items in the palletizing head is particularly preferred during its transfer movement.

[0028] A particularly advantageous embodiment of the invention provides for positioning in the palletizing head during its transfer movement, wherein the inertia of the piece position during the acceleration and deceleration of the palletizing head is used for positioning in the palletizing head.

[0029] Advantages arise, among other things, from increased throughput while simultaneously reducing wear on the drives used for palletizing individual loads and, more generally, on the drives used for automated handling. This is achieved by reducing waiting times between coordinated movements during palletizing, as well as the resulting discontinuities in the upstream flow of individual loads. Such waiting times and the associated discontinuities are accompanied by stop delays and accelerations when resuming movement. Streamlining the process of layering individual loads and palletizing, particularly by shortening the mutual waiting times during palletizing, helps to avoid discontinuities in the upstream flow of individual loads from the grouping station.

[0030] The following exemplary embodiment of the invention and its advantages will be explained in more detail with reference to the single accompanying figure. The relative sizes of the individual elements in the figure do not always correspond to their actual sizes, as some shapes are simplified and others are enlarged for better illustration in relation to other elements.

[0031] Fig. Figure 1 shows a schematic perspective view of a palletizing head with a support surface for each layer of individual items to be picked up and transferred from a receiving station to a destination. This support surface can be removed from beneath the layer of items at the destination for placement within the palletizing head. The palletizing head can have a rear push bar, also referred to as a push beam, and a front support bar, both of which are advantageously driven or can be driven by a motor, preferably in a coordinated and / or coupled manner. Advantageously, the palletizing head can also have lateral centering bars, which are preferably adjustable relative to each other by a motor. Guide slot-like recesses in the centering bars can be provided to allow movement of the support and push bars, which are arranged in the same plane as the centering bars.Alternatively, the opposing centering strips and the opposing support and push strip can be arranged in different planes, from which they can be brought to the system from the circumference of a piece goods position.

[0032] For identical or similarly functioning elements of the invention, identical reference numerals are generally used. Furthermore, for the sake of clarity, only those reference numerals necessary for describing the figure are shown in the single figure. The illustrated embodiment merely represents an example of how the palletizing head and the method according to the invention can be configured and does not constitute an exhaustive limitation.

[0033] A in Fig. A palletizing head 1, shown in whole or in part, has a support level 2 for each layer of general cargo to be picked up and transferred from a receiving point to a destination. The support level 2 can be removed from beneath the general cargo layer at the destination for the purpose of depositing the general cargo layer in the palletizing head 1. The palletizing head 1 is movable between the receiving point and the destination.

[0034] The direction in which the individual items are placed at the destination is advantageously oriented approximately perpendicular to the loading direction of the individual items at the receiving point. Particularly preferably, the placement is in a direction indicated by an arrow. Fig. 1. Indicated placement direction A is normal to the support plane 2 downwards out of the palletizing head 1, whereas the direction indicated by an arrow points inwards. Fig. 1. The indicated loading direction B runs parallel to the support plane 2.

[0035] In other words, the loading direction B runs parallel to the horizontally oriented support plane, whereas the unloading direction A preferably runs vertically.

[0036] The individual items can be stabilized and positioned within the palletizing head 1 during both its pickup at the receiving point and its placement at the destination, in coordination with a positioning movement of the palletizing head 1 between the receiving point and the destination.

[0037] This allows the palletizing head 1 to begin its movement, referred to as the transfer movement, from the receiving point to the destination more quickly than if the individual items were already in their delivery position within the palletizing head 1 during loading at the receiving point, as is the case with the prior art. This reduces the waiting time of the palletizing head 1 before it begins its transfer movement. The palletizing head 1 starts its transfer movement after the individual items are on the support level 2, but before they have reached their delivery position.

[0038] The position of the unit load in the palletizing head 1 is maintained during the transfer movement.

[0039] The stabilization and positioning of the unit load in the palletizing head 1 is particularly preferably carried out during its transfer from the receiving point to the destination, briefly during the transfer movement, advantageously at the beginning and / or at the end of the transfer movement.

[0040] A particularly advantageous embodiment of the invention provides for positioning in the palletizing head 1 during the transfer movement, whereby the inertia of the unit position is used during the acceleration and deceleration of the palletizing head 1.

[0041] The palletizing head 1 can have at least one motor-driven support bar 3 and at least one motor-driven push bar 4, each of which is indicated by double arrows V in Fig. The indicated displacement directions VST (support strip 3) and VSC (push strip 4) are movable parallel to the loading direction B. The layer of goods received in the palletizing head 1 is located between the support strip 3 and the push strip 4.

[0042] Advantages arise, among other things, from the counter-support of the individual items during the transfer and during the movement of the palletizing head, which already makes higher speeds possible at this stage.

[0043] In the palletizing head 1 described above, the support bar 3 and the push bar 4 can be positioned within the palletizing head 1 in a coordinated manner and in coordination with a positioning movement of the palletizing head 1 between the receiving point and the destination point to stabilize the position of the unit load during its pickup at the receiving point and during its placement at the destination point.

[0044] The coordination with a positioning movement of the palletizing head 1 can be achieved such that the support bar 3 and the push bar 4 perform a stabilizing and positioning movement corresponding to the inertial movement of the goods layer during acceleration and / or deceleration of the palletizing head 1. The advantageously coordinated, for example coupled, stabilizing and positioning movement of the support bar 3 and the push bar 4 preferably allows the goods layer just enough freedom to perform its inertial movement.

[0045] According to an advantageous embodiment, the support bar 3 and the push bar 4 define limits, at least towards the end of the positioning movement of the palletizing head 1, within which the discharge position of the unit load lies in the palletizing head 1.

[0046] In the palletizing head 1, motor-driven centering strips 5 can be arranged on both longitudinal sides of the support plane 2, which are movable in opposite directions to each other in displacement directions VZ perpendicular to the loading direction B and approximately parallel to the support plane 2.

[0047] In such a palletizing head 1, the centering strips 5 can be positioned against each other to stabilize a layer of goods held in the palletizing head 1 and can be placed against opposite longitudinal sides of the layer of goods.

[0048] Additional advantages result from a four-sided guidance of the piece layer during the transfer, which ensures that the layer pattern is maintained both at high transfer speed of the piece layer into the palletizing head 1, and at high positioning movement acceleration and speed of the palletizing head 1.

[0049] Positioning and stabilization can be achieved almost entirely without a drive. At least, motorized drives, if any, for motorized support 3 and push rails 4 arranged in the palletizing head 1, as well as any centering rails 5, can be designed and / or powered in such a way that their movement is synchronized with the positioning – i.e., the sliding – of the goods layer, but without actually pushing or having to push the goods layer itself. The movement, i.e., the sliding of the goods layer within the palletizing head 1, is accomplished by its inertia.

[0050] It is important to emphasize that in this context, a quasi-powerless positioning also exists when, for example, motor-driven or driveable support 3 and push 4 strips are used to create or support a transition from static friction to sliding friction under the presence of an acceleration that causes a change in the momentum of the piece position, both under increasing and decreasing speed.The same applies to reaching the discharge position within the palletizing head 1 if, for example, motor-driven or driveable support 3 and push bars 4 and / or, for example, motor-driven or driveable centering bars 5 are used to stop a piece of goods in the discharge position that is intentionally and specifically shifting in the palletizing head due to its inertia during acceleration, both during increases and decreases in speed relative to the palletizing head 1.

[0051] It is also important to emphasize that during the entire process of the deliberate slippage of the goods layer, due to its inertia within the palletizing head 1, the motor-driven or driveable support bars 3 and push bars 4 and / or, for example, motor-driven or driveable centering bars 5 can actually or nearly come into contact with opposite and / or adjacent sides of the goods layer. This contact, however, advantageously occurs without force, at least in the sense of the above definition of quasi-powerless operation. In other words, the goods layer slips within the palletizing head 1 during its acceleration and deceleration, with the motor-driven or driveable support bars 3 and push bars 4 located on opposite sides of the goods layer preceding or following the slipping goods layer.For example, the push bar 4 follows the position of the individual items as they shift, whereas the support bar leads the position of the individual items at least until they reach the delivery position. This stabilizes the position of the individual items in the palletizing head 1 during their transfer from the receiving point to the destination.

[0052] In the palletizing head 1, which is equipped with support 3 and push strips 4 as well as centering strips 5, at least the support strip 3 can be held and guided in the centering strips 5, which move in opposite directions. For this purpose, the centering strips 5 can be provided with slots 6, for example designed as guide slots, through which the support strip 3 can be movably arranged on the longitudinal sides 7 of the palletizing head 1.

[0053] The push bar 4 can be arranged on a linkage 8, which is suitable for raising the push bar 4 sufficiently above the support level 2 to allow a layer of goods to pass between itself and the support level 2 when raised. The linkage 8 can raise the push bar 4 during the raising process so that a layer of goods can be pushed from the grouping station onto the support level 2 and into the palletizing head 1, passing under the push bar 4. Alternatively, the linkage 8 can lift the push bar 4 over a layer of goods waiting at the grouping station and set it down behind it to bring the layer of goods into the palletizing head 1 for the purpose of being pushed onto the support level 2.

[0054] The support level 2 can be formed by a movable base of the palletizing head 1. For example, the movable base can comprise a roller or cylinder base with a multitude of parallel rollers or cylinders. These can be connected on both sides by guide chains. By driving the opposing guide chains, the rollers or cylinders beneath the layer of goods can be removed. The axes of rotation of the rollers or cylinders run parallel to the support level 2 and perpendicular to the loading direction B.

[0055] According to an advantageous further development of the palletizing head 1, the support level 2 arranged within the palletizing head 1 and removable for placing a layer of individual items can be divided, in particular by making sections of the multi-part support level 2 movable apart.

[0056] The base forming the support level 2 can, for example, be divided in half, whereby to remove the support level 2 the two halves are pulled back in opposite directions.

[0057] With a suitably designed palletizing head 1, the divided, in particular two-part, support level 2 can be removed at the destination below the layer of individual items. This allows the palletizing head 1 to release the layer of individual items for placement on a pallet stack by moving the two halves of the support level 2 apart in a direction parallel to the loading direction B.

[0058] For example, one described previously and / or in Fig. 1 Palletizing head 1, shown in whole or in part, can be designed to carry out a palletizing process for layers of individual items as described below.

[0059] In the process for palletizing layers of individual goods using a palletizing head 1, the layers of individual goods are picked up at a transfer station and pushed onto a support level 2 of the palletizing head 1.

[0060] The individual loads are slid onto support level 2 of the palletizing head 1 in order to be placed at a destination location by means of the palletizing head 1. Placement at the destination location is accomplished by removing support level 2 from beneath the load layer located in the palletizing head 1.

[0061] The procedure advantageously provides that a storage direction A of the general cargo position is oriented approximately perpendicular to a loading direction B of the general cargo position at the receiving point when it is stored at the destination.

[0062] The procedure provides that the unit load is positioned, for example, at the edge within the palletizing head 1 and relative to it, during the transfer of the palletizing head 1 to the destination, after which the unit load is moved further on the support level in the loading direction B, before the support level 2 is removed below the unit load to be placed when the destination is reached.

[0063] The further movement of the individual items in the loading direction advantageously refers to the direction of movement B of the individual items within the palletizing head 1. This further movement occurs during the transfer of the palletizing head 1 to its destination, for example, at the beginning and / or end of the transfer. Particularly preferably, the further movement is carried out by utilizing the inertia of the individual items during the acceleration and / or deceleration of the palletizing head 1 during the transfer.

[0064] In this process, the unit load is advantageously positioned in a first position within the palletizing head 1 and relative to it, after which, during the transfer of the palletizing head 1 to the destination and at least temporarily during a braking movement of the palletizing head 1 shortly before reaching the destination on the support level 2 in the loading direction, the unit load is moved further into a second position within the palletizing head 1 and relative to it, after which the support level 2 is removed below the unit load to be placed when the destination is reached.

[0065] The procedure may stipulate that the support level 2 is divided, advantageously divided into two parts.

[0066] The procedure can provide that the divided support level 2 is removed at the destination below the unit load layer and releases it for placement on a pallet stack by moving sections of the multi-part support level 2 apart.

[0067] Advantageously, the method provides that the divided, in particular two-part, support level 2 is removed at the destination below the unit load layer and releases it for placement on a pallet stack by moving the two halves of the support level 2 apart in one direction, preferably in two opposite directions, parallel to the loading direction B.

[0068] The method can provide for stabilization of the unit load position during its positioning within the palletizing head 1. For this purpose, at least one motor-driven support bar 3 and at least one motor-driven push bar 4 can be arranged in the palletizing head 1, each movable in displacement directions VST, VSC parallel to the loading direction B, with the unit load position in the palletizing head 1 being located between the support bar 3 and the push bar 4.

[0069] The procedure may provide that the position of the unit load is moved further on the support level 2 in loading direction B during the transfer of the palletizing head 1 to the destination, under coordinated displacement movement of the support bar 3 and the push bar 4 in their displacement directions VST, VSC.

[0070] According to the procedure, the position of the unit load can be positioned approximately in the middle of the palletizing head 1 during the transfer movement of the palletizing head 1 to the destination by means of the displacement movements of the support bar 3 and the push bar 4 in their displacement directions VST, VSC.

[0071] It is evident that the invention can be realized by a palletizing head 1, also referred to as a loading unit or encompassed by a loading unit, and alternatively or additionally by a method for palletizing layers of goods, referred to briefly as layers, using such a palletizing head 1.

[0072] Advantageously, the transfer of the layer from the grouping station to the loading unit, its positioning in the loading unit, and its transfer to the loading station are all accomplished with continuous counter-support. The four-sided guide allows for faster insertion of the layer, and simultaneous positioning and transfer to the loading station. Positioning is synchronized with the deceleration or acceleration of the transfer movement. These superimposed movements during the transfer utilize the layer's inertia and the braking or acceleration torque of the loading unit to reduce the torque required by the layer pusher.

[0073] Advantages of the invention arise, in addition to a complete solution to the underlying problem, from a higher unit throughput, also referred to as higher layer performance, since the front and rear holding of the layer between the slide and the counter-holder after insertion allows the transfer process to be started earlier, even though the layer is not yet definitively positioned. The slide and counter-holder can be formed by or comprise the push bar 4 and the support bar 3. Alternatively, a slide on the grouping station side can be provided for the purpose of, or during, the sliding process.

[0074] Additional advantages arise from the lower torque and reduced drive power required for positioning the slide compared to the prior art, as the positive effects of the superimposed movements, which allow the utilization of the inertia of the individual parts layers, can be exploited. This results in improved protection of the mechanical components through lower torque and a correspondingly increased throughput.

[0075] It is important to emphasize that the palletizing head 1 can have one or a combination of the features previously described in connection with the process, just as the process can have and / or implement one or a combination of several features previously described in connection with the palletizing head 1.

[0076] It is equally important to emphasize that the palletizing head 1 and / or the method may alternatively or additionally have one or a combination of several features described in the preceding description of the embodiment shown in the drawing, in conjunction with the prior art and / or in one or more of the documents mentioned as prior art and / or in the preceding description.

[0077] The invention has been described with reference to a preferred embodiment. However, it is conceivable to a person skilled in the art that modifications or changes to the invention can be made without departing from the scope of protection of the following claims.
