Definitions
- the invention relates to a palletizing robot head, a palletizing robot and a method for palletizing at least one layer to be palletized.
- Palletizers are used, for example, in the beverage bottling process to palletize layers of filled containers and/or packages.
- layers of containers such as bottles or cans or packages are formed.
- the layers formed can be stacked or palletized to form a pallet stack using the palletizer.
- a palletizing robot head, a palletizing robot and a corresponding method are known from US 2020/0062518 A1.
- the palletizing robot head has a gripping device, an upper cushion and support layers. To pick up a layer, the layer is first contacted on an upper side by the upper cushion, then gripped and lifted by the gripping device. The support layers are then moved under the raised layer to support the layer.
- Another palletizing robot head is known, for example, from DE 102008 035 330 A1.
- This palletizing robot head has drivable rollers that can support a picked-up layer, as well as a rolling roller arranged laterally on a feed side of the palletizing robot head.
- the rolling roller can contact containers and/or packages of the layer to be palletized and lift them over the rolling roller while the rolling roller rotates.
- the containers or packages can be transported onto the rollers or the support formed by them, whereby the rollers can transport the containers or packages further away from the rolling roller so that further containers and/or packages forming the layer can be picked up.
- the object of the present invention is to provide a palletizing robot head, a palletizing robot and a method which overcome these disadvantages.
- a palletizing robot head for a palletizing robot for palletizing packages or containers, comprising a first assembly and a second assembly, wherein the first assembly and the second assembly can be moved in opposite directions to one another between an extended position and a retracted position
- the first assembly is extended from the palletizing robot head in the extended position and is designed to receive at least one layer to be palletized and is retracted into the palletizing robot head in the retracted position
- the second assembly is designed as a counterweight to the first assembly at least in the extended position and between the extended position and the retracted position.
- the invention thus provides a palletizing robot head in which a weight shift caused by the extension of the first assembly is compensated by the second assembly.
- the second assembly acts as a counterweight to the first assembly during and after extension.
- the common center of gravity of the first and second assemblies therefore remains close to the palletizing robot head during and after extension of the first assembly.
- a first torque that the first assembly causes on the palletizing robot head by extending out of the palletizing robot head is canceled out or compensated by a second torque that acts on the palletizing robot head by extending the second assembly out of the palletizing robot head.
- a smaller palletizing robot can be used to move the palletizing robot head, since not only the load capacity but also the The position of the center of gravity and the inertia of the tool, in this case the palletizing robot head, can be taken into account.
- the payload of a palletizing robot may be sufficient for an application, although the position of the center of gravity and the inertial forces arising from the dynamics can overload it.
- This overload can be avoided by the second assembly acting as a counterweight to the first assembly.
- the first assembly can be extended in the extended position against the loading direction.
- the second assembly can then be extended in the loading direction.
- the first assembly and the second assembly are arranged at a distance from one another in the extended position.
- the distance is such that the first assembly can accommodate the at least one layer to be palletized independently of the second assembly.
- the first assembly can, for example, clamp or grip the at least one layer to be palletized, or just enclose it at least partially.
- the first assembly can be designed, for example, to push the at least one layer to be palletized in the direction of the second assembly when it is moved into the palletizing robot head.
- the at least one layer to be palletized can be at least partially pushed onto the second assembly while the second assembly is moved into the palletizing robot head, wherein the second assembly can be held stationary by a corresponding movement of the palletizing robot head.
- the retracted position can also be a retracted position, wherein in the retracted position the palletizing robot head is moved in its entirety with at least one layer to be palletized picked up. Since the second assembly is designed as a counterweight to the first assembly, the first assembly can also be regarded as a counterweight to the second assembly. To deposit the at least one layer to be palletized, the first assembly can be extended from the palletizing robot head.
- the second assembly can be moved away from under the at least one layer to be palletized, particularly when the second assembly supports the at least one layer to be palletized in the retracted position, the first assembly being moved by a corresponding movement of the palletizing robot head during When moving out of the palletizing robot head, the first assembly can push the at least one layer to be palletized, e.g. from the second assembly, when moving out of the palletizing robot head.
- This means that damage to the at least one layer to be palletized can be avoided with little effort when picking up and/or putting down.
- the picking up and putting down of the at least one layer to be palletized can be carried out more quickly than in the prior art.
- the assemblies can, for example, be movably mounted on linear guides extending along the loading direction.
- the linear guides can be attached to the palletizing robot head. Furthermore, the linear guides of both assemblies can be aligned parallel to one another.
- the first assembly and the second assembly can be moved simultaneously in opposite directions to one another between the extended position and the retracted position.
- the first and second assemblies can have a common drive or two synchronized drives. The movement of the assemblies when extending and retracting can therefore take place synchronously, whereby the distances covered by the two assemblies relative to the palletizing robot head do not necessarily have to be the same, but can also be different.
- the common drive may drive the first assembly and be coupled to the second assembly via a transmission, or vice versa.
- the transmission may have a gear ratio that may be selected such that the first and second assemblies are moved synchronously.
- the transmission may have a gear ratio that may be selected such that the first and second assemblies are moved by substantially the same path or distance relative to the palletizing robot head, eg relative to a reference point of the palletizing robot head.
- the common drive may be coupled to the first assembly via a first gear and to the second assembly via a second gear. The gear ratios of the first and second gears may be selected such that the first and second assemblies are moved by substantially the same path or distance relative to the palletizing robot head, eg relative to a reference point of the palletizing robot head.
- a first torque acting from the first assembly on the palletizing robot head may be substantially equal to a second torque acting from the second assembly on the palletizing robot head.
- first and second assemblies can be designed in such a way that the weight of the at least one layer to be palletized changes the balance between the first and second torque only insignificantly.
- the second assembly can be moved independently of the first assembly in order to adapt the distance covered by the second assembly when extending and thus the second torque to the first torque.
- the additional torque acting on the palletizing robot head from the at least one layer to be palletized in the extended position and between the extended position and the retracted position can thus be compensated by the second torque acting on the palletizing robot head from the second assembly.
- the first assembly can have at least one centering frame for receiving the at least one layer to be palletized, wherein the centering frame is preferably designed to move at least one of the layers to be palletized.
- the centring frame can be designed in such a way that at least one layer to be palletized can be framed laterally by it.
- the centring frame can be positioned in front of and behind the at least one layer to be palletized with respect to the loading direction.
- the frame elements have a stability that is sufficient to push the at least one layer to be palletized when it is picked up and put down or to stop the movement of the at least one layer to be palletized.
- the second assembly may comprise a support device for the at least one layer to be palletized, wherein the support device is designed in particular as a support plate for arranging under the at least one layer to be palletized.
- the support device can be used to provide additional support for the at least one layer to be palletized in the retracted position and at least partially between the extended position and the retracted position.
- a support plate can be arranged as a support device under the at least one layer to be palletized in order to support all parts of the layer from below.
- the support device can have two rails that can be pushed under at least one layer to be palletized on opposite sides. In the case of a one-piece layer in particular, the rails can be sufficient as support from below.
- the at least one layer to be palletized can, for example, have one or more containers and/or packages, or consist of or be formed from these.
- the container can be or have a can, a bottle, e.g. a glass bottle or a plastic bottle, e.g. a PET bottle.
- the container can be or have a bag, pouch, packaging, cardboard or the like.
- the package can have bottles and/or containers or consist of these, wherein the bottles and/or containers can be assembled to form the package, e.g. glued together, packaged and/or connected.
- the layer can be formed from an arrangement of several rows of containers and/or packages, for example from 2x2 containers and/or packages, ie two rows of two containers and/or packages arranged next to one another.
- the layer can be formed from an arrangement
- the system can be formed from 2x2 to 24x24 containers and/or packages, for example 2x4, 8x6, 6x8, 10x12,12x12, 16x14, or the like.
- the palletizing robot head may comprise a support frame, wherein the first assembly and the second assembly are movably mounted along the support frame between the extended position and the retracted position.
- linear guides for the first assembly and for the second assembly can also be attached to the support frame.
- a drive for the two assemblies or separate drives for each assembly can be attached to the support frame.
- first assembly in the extended position can be offset from the retracted position by a first distance, for example, and the second assembly can be offset from the retracted position by a second distance, wherein the second distance has a length which corresponds to at least one third, preferably at least 50%, of the sum of the first and second distances.
- the second assembly can be moved relative to the palletizing robot head by the same path or the same distance by which the first assembly is moved relative to the palletizing robot head. This allows the first and second assemblies to be moved essentially synchronously with the palletizing robot head. In some embodiments, however, the length of the first path can also be less than half the length of the second path.
- the invention relates to a palletizing robot comprising a robot arm and a palletizing robot head connected to the robot arm according to the preceding description.
- the palletizing robot can have a control unit and/or be controlled by a control unit.
- the control unit can, for example, control motors of the palletizing robot and/or the palletizing robot head.
- the palletizing robot can be designed to superimpose a movement of the robot arm with a movement of the second assembly and the first assembly when picking up at least one layer to be palletized, wherein the second assembly preferably remains stationary during the movement.
- the palletizing robot head When moving the first and second assemblies from the extended position to the retracted position, the palletizing robot head can, for example, move in the direction of the second assembly at the same speed with which the second assembly is retracted into the palletizing robot head. This allows the second assembly to hold its position for an observer.
- the first assembly can have a speed for an observer when retracting into the palletizing robot head that corresponds to the sum of the retraction speed of the first assembly and the speed of the palletizing robot head.
- the palletizing robot head can be set in motion as soon as the first assembly is retracted with the at least one layer to be palletized, preferably in the direction of the storage location of the at least one layer to be palletized. This can accelerate the transport of the at least one layer to be palletized.
- the palletizing robot can be designed, for example, to superimpose a movement of the robot arm with a movement of the second assembly and the first assembly when depositing at least one layer to be palletized, wherein the first assembly preferably remains stationary during the movement.
- the palletizing robot head can, for example, move away from the first assembly in the opposite direction to the extension direction of the first assembly at the same speed as the first assembly is extended out of the palletizing robot head. This allows the first assembly to hold its position for an observer.
- the second assembly when extending into the palletizing robot head can have a speed for an observer that corresponds to the sum of the extension speed of the second assembly and the speed of the palletizing robot head.
- the palletizing robot head can thus be set in motion as soon as the first assembly is extended and the at least one layer to be palletized is deposited, preferably in the direction of the pickup location of the at least one layer to be palletized. This allows the movement to the pickup location to be accelerated.
- the palletizing robot head is mounted so as to be rotatable about an axis that is perpendicular to the direction of movement of the first and second assemblies when moving in and out and can preferably be arranged vertically.
- the palletizing robot head can then be rotated, preferably by 180°, about this vertical axis, so that the palletizing robot head is not only moved in the direction of the storage location when picking up the at least one layer to be palletized or when moving in the first assembly, but is also moved in the direction of the pick-up location when setting down the at least one layer to be palletized or when moving out the first assembly.
- the invention further relates to a method for palletizing at least one layer to be palletized with a palletizing robot according to the preceding description, comprising the following steps: moving the palletizing robot head of the palletizing robot into a receiving position, wherein in the receiving position the first assembly of the palletizing robot head is extended out of the palletizing robot head in the opposite direction to a loading direction and the second assembly is extended out of the Palletizing robot head is extended; picking up at least one layer to be palletized with the first assembly in the picking position and moving the first assembly into the palletizing robot head in the loading direction, wherein when the first assembly is moved in, the palletizing robot head is moved in the loading direction and the second assembly is moved into the palletizing robot head such that the second assembly is held stationary; moving the palletizing robot head into a palletizing position; and moving the second assembly in the palletizing position out of the palletizing robot head in the loading direction, wherein when the second assembly is moved out, the palletizing robot head is moved in the loading direction and the first assembly is moved out of the palletizing robot head to deposit the
- the method can be carried out with a palletizing robot head and/or palletizing robot as described above.
- a palletizing robot head and/or palletizing robot as described above can be set up to carry out the method.
- the method can also be carried out with a two-column machine, for example.
- the first and second assemblies can either already be in the extended position or can be moved from the retracted position into the extended position.
- the first assembly can be extended from the palletizing robot head and the first assembly can be arranged on at least one layer to be palletized.
- the first assembly can then pick up the at least one layer to be palletized, e.g. by arranging a centering frame of the first assembly horizontally adjacent to the at least one layer to be palletized.
- Several layers to be palletized can already be stacked at the receiving position. These can then be picked up by the first assembly at the same time.
- the first assembly can then be moved into the palletizing robot head in the loading direction, with the first assembly taking the at least one layer to be palletized with it.
- the second assembly can be moved into the palletizing robot head at a retraction speed opposite to the loading direction. whereby the palletizing robot head is moved at the same speed in the loading direction and thus in the direction of the second assembly, so that for an observer the second assembly is held stationary.
- the second assembly forms a counterweight to the first assembly in the extended position and when the first assembly is retracted into the palletizing robot head.
- the second assembly can therefore be retracted into the palletizing robot head at the same time as the first assembly.
- the palletizing robot head can be moved further from the pick-up position into the palletizing position.
- This movement can begin as soon as the first and second assemblies are retracted into the palletizing robot head.
- the first and second assemblies are extended out of the palletizing robot head.
- the first assembly can be extended out of the palletizing robot head at an extension speed against the loading direction. Meanwhile, the palletizing robot head can move at the same speed in the loading direction. This holds the first assembly stationary in the palletizing position.
- the method may be repeated at least once or several times to form a pallet stack of layers to be palletized. In some embodiments, some, several or all steps of the method may be carried out in reverse order to remove one or more layers from a pallet stack.
- the first assembly and the second assembly can, for example, be arranged one above the other in the entry position.
- the centers of gravity of the two assemblies can, for example, be located horizontally above or on top of each other. It is also conceivable that before the step of picking up at least one layer to be palletized, for example the first assembly can be adapted to the dimensions of the at least one layer to be palletized, for example its footprint.
- the first assembly may comprise a centring frame which can be adapted to the dimensions of the at least one layer to be palletized using a centring frame drive.
- the first assembly can at least partially enclose the at least one layer to be palletized after moving into the receiving position.
- the palletizing robot head can be rotated about a vertical axis when moving into the palletizing position, preferably by 180°.
- step, picking up at least one layer to be palletized, and/or step, extending the second assembly for example, the first assembly can be extended by a first distance and the second assembly can be extended by a second distance, wherein the second distance has a length which corresponds to at least one third, preferably at least 50%, of the sum of the first and second distances.
- the second assembly can be moved relative to the palletizing robot head by the same path or the same distance by which the first assembly is moved relative to the palletizing robot head. This allows the first and second assemblies to be moved essentially synchronously with the palletizing robot head. In some embodiments, however, the length of the first path can also be less than half the length of the second path.

- the at least one layer 102 to be palletized can be accommodated by the first assembly 7 independently of the second assembly 3.
- the second assembly 3 acts as a counterweight to the first assembly 3, so that a center of gravity of the palletizing robot head 1 can remain close to the palletizing robot head 1.
- the palletizing robot head 1 is therefore more stable and can be moved in a controlled manner while the two assemblies 3, 7 are extended and retracted.
- the palletizing robot head 1 can also be moved during the extension and retraction of the two assemblies 3, 7.

- the ratio of the first distance to the second distance S1/S2 can be selected such that it can essentially correspond to the ratio of two weight forces G1/G2, wherein the weight force G1 can correspond to a weight force of the first assembly 7 acting on the center of gravity of the first assembly 7, possibly with a layer 102 to be transported, and the weight force G2 can correspond to a weight force acting on the center of gravity of the second assembly 3.

- the layer 102 can be arranged, for example, at the palletizing position and/or be a deposited layer of a pallet stack. Furthermore, the distance to a pallet stack and/or a layer 102 provided to be picked up at the pick-up position can be measured.
- the palletizing robot 100 and/or the palletizing robot head 1 can have a height sensor to detect a height of the palletizing robot head 1 above a reference plane.
- the pick-up position can be a position in which at least one layer 102 to be palletized that has been provided can be picked up by the palletizing robot 100 and/or the palletizing robot head 1.
- the palletizing position can be a position in which the at least one layer 102 to be palletized that has been picked up by the palletizing robot 100 and/or the palletizing robot head 1 can be palletized and/or deposited.
- Figures 5a to 5i show nine different points in time of a method 500 according to the invention for palletizing at least one layer 102 to be palletized, wherein the steps of the method 500 follow the flow chart of Figure 6.
- Figure 5a shows a point in time at which the palletizing robot head 1 is between the pick-up position and the palletizing position.
- the palletizing robot head 1 can be in the extended position in which the first and second assemblies 3, 7 are extended from the palletizing robot head 1.
- the first assembly 7 can be extended relative to the palletizing robot head 1 or the support frame 6 against the loading direction B.
- the second assembly 3 can be extended relative to the palletizing robot head 1 or the support frame 6 in the loading direction B.
- the point in time shown in Figure 5a can be after a point in time at which the palletizing robot 100 and/or the palletizing robot head 1 has deposited and/or palletized at least one layer 102 to be palletized.
- no layer 102 to be palletized is held and/or transported by the palletizing robot 100 and/or the palletizing robot head 1. It can also be provided that at the time shown in Figure 5a at least one layer 102 to be palletized can be provided, e.g. at or near the pick-up position. In this case, several layers 102 stacked on top of one another can already be provided at the pick-up position.
- Figure 5b shows a point in time at which the palletizing robot 100 and/or the palletizing robot head 1 may have been moved into the receiving position according to step 501, so that the centering frame 2 or the first assembly 7 can at least partially receive or enclose at least one layer 102 to be palletized according to step 502.
- the at least one layer 102 to be palletized can be moved by the first assembly 7 in the loading direction B, ie by moving the first assembly 7 and the second assembly 3 into the palletizing robot.
- the head 1 can be pushed onto the support plate 3 of the second assembly 3.
- Figure 5c shows a point in time at which the at least one layer 102 to be palletized is at least partially pushed onto the support plate 3.
- the first assembly 7 is moved relative to the palletizing robot head 1 or the support frame 6 and the second assembly 3 or the support plate in the loading direction B.
- the palletizing robot head 1 or the support frame 6 is also moved relative to the second assembly 3 in the loading direction B.
- the second assembly 3 can be moved relative to the palletizing robot head 1 or the support frame 6 against the loading direction B.
- the time required to push the at least one layer 102 to be palletized onto the support plate can also be reduced.
- the movement of the palletizing robot head 1 in the loading direction can take place at the same speed with which the second assembly 3 or the support plate is inserted into the palletizing robot head 1. The movement of the palletizing robot head 1 is thus superimposed on the insertion movement of the second assembly 3.
- the robot 100 and/or the robot arm 101 can be moved into a palletizing position according to step 503, as shown in the sequence of Figures 5d and 5e.

- the palletizing robot head 1 or the support frame 6 can be moved relative to the first assembly 7 and/or the centering frame 2, with the first assembly 7 being extended from the palletizing robot head 1.
- the first assembly 7 or the centering frame 2 can contact and/or hold the at least one layer 102 to be palletized, so that the second assembly 3 or the support plate can be pulled out from under the at least one layer 102 to be palletized. If the second assembly 3 is fully extended and/or pulled out from under the at least one layer 102 to be palletized, the at least one layer 102 to be palletized can be or will be palletized.
- the movement of the palletizing robot head 1 in the loading direction takes place at the same speed with which the first assembly 7 or the centering frame 2 is extended from the palletizing robot head 1.
- the movement of the palletizing robot head 1 is thus superimposed on the extension movement of the first assembly 7, so that the first assembly 7 or the centering frame 2 remains stationary.
- the time required for depositing or palletizing the at least one layer 102 to be palletized by the second assembly 3 can also be reduced.
- the support plate 3 can be completely moved.
- the first assembly 7 can be completely extended from the palletizing robot head 1.
- the first assembly 3 and the second assembly 7 can then be in the extended position.
- the palletizing robot head 1 and/or the palletizing robot 100 can then be moved into the receiving position, as shown in Figure 5i, in order to palletize another layer 102.
