Technical Field

The invention relates to a palletizing device for placing a layer of articles on a transport aid, such as a pallet, or on a stack on a transport aid, comprising a lifting device which is configured in the form of a column and has at least three sides, and has at least three separate guides, wherein in each case one of the at least three guides is arranged on at least three sides, and wherein in each case at least one carriage is guided on the at least three guides so that it can be moved in a vertical direction. The invention also relates to a method for operating a corresponding palletizing device for placing a layer of objects on a transport aid or on a stack of layers located on a transport aid.

Background

Palletizing devices are used for arranging objects, in particular bulk goods, or for containers which are transported on transport aids, in particular pallets. For this purpose, the articles are first combined into individual article layers and then placed in layers on the transport aid or on a stack of layers already on the transport aid, for example. To be palletized, the articles generally first pass through a feeding device in which the articles arriving one after the other, initially in one or more rows, are rearranged and/or assembled into a stackable article layer. The stackable object layers are then successively transferred to a palletizing device, which places the object layers in the desired stacking position, in particular on a transport aid.

For this purpose, the palletizing device comprises, for example, a lifting device to which a plurality of carriages are connected so as to be movable in the vertical direction. On one of these carriages, for example, a placement device is fixed. In the palletization process, in each case one stackable object layer is transported onto the transport plane of the depositing device and the carriage with the depositing device is moved vertically on the lifting device. Subsequently, a layer of the article is placed onto the stack. In this case, the lowermost layer of articles of the stack is placed directly on the transport aid.

A generic palletizing device is known, for example, from DE102014223319a 1. The palletizing device comprises a lifting mechanism column with three separate guiding devices, which are arranged on different sides of the lifting mechanism column. On each guide, in each case one transfer station is guided so as to be vertically movable.

Document EP2610197a1 discloses a palletizing device comprising a lifting device to which two carriages are connected so as to be able to move vertically. In this case, the conveyor belt is provided on one carriage, and the placement device is provided on the other carriage. During palletization, the layers of articles are transferred by the conveyor belt onto the bottom surface of the depositing device.

Document US2014/0294553a1 also discloses a palletizing device comprising a lifting device to which two carriages are connected so as to be able to move vertically. In this case, the conveyor belt is provided on one carriage, and the placement device is provided on the other carriage.

A palletizing device is also known from document EP2881347B 1. The palletizer comprises a lifting mechanism column with two separate guiding devices. In this case, the transfer station is guided so as to be vertically movable on one guide, and the loading station is guided so as to be vertically movable on the other guide.

Documents DE102007022908a1, EP2842895a1, DE4114215a1, EP2653417a1, DE19943800a1, DE102015206124a1, DE102011088849a1 and EP2547612B1 also disclose palletizing devices and methods for palletizing layers of objects.

Disclosure of Invention

The problem addressed by the present invention is to improve a palletizing device of the type mentioned at the outset. In particular, the problem addressed by the present invention is to reduce space requirements and increase flexibility in layout design.

Solution scheme

This problem is solved by a palletizing device having the features of claim 1. Advantageous configurations and improvements of the invention are the subject matter of the dependent claims.

A universal palletizer for placing a layer of objects on a transport aid or on a stack of layers on a transport aid comprises a lifting device which is configured in the form of a column and has at least three sides. In this case, the columns extend in the vertical direction and are advantageously configured as right prisms. The transport aid is for example a pallet.

The lifting device has at least three separate guiding devices, wherein in each case one of the at least three guiding devices is arranged on at least three sides of the lifting device, and wherein in each case at least one carriage is guided on the at least three guiding devices so as to be movable in the vertical direction. Thus, in each case one carriage is provided on at least three sides of the lifting device.

According to the invention, at least three sides of the lifting device are oriented parallel to the vertical direction and in an inclined manner relative to one another, wherein in each case two sides enclose an angle between one another. In this case, at least two of the angles between two of the three side faces are in each case not 90 °. Preferably, in each case, each of the three angles between two of the three sides is not 90 °.

Thus, in particular, the lifting device has a cross section other than rectangular. Therefore, the lifting device has a shape different from a rectangular parallelepiped. In particular, the side of the lifting device on which the guide is provided is not the side of a cuboid. For example, the lifting device has a substantially triangular cross-section. In this case, three sides (with corresponding extensions in a direction at right angles to the vertical) may form a triangular cross-section. For example, the lifting device has exactly three sides, wherein exactly one guide is provided on each side, on which guide in each case one carriage is guided.

Since only cylindrical lifting devices are provided in order to move the three components of the palletizing device in the vertical direction on in each case one carriage, material, in particular steel, is advantageously saved. The space requirement of the lifting device is also advantageously reduced, since the cross-section of the cylindrical lifting device is substantially triangular. It has been shown that sufficiently high stability and load-bearing strength can be obtained with a lifting device in the form of a prism having a substantially triangular cross-section.

The angle between the sides where the guiding means are arranged is in a plane defined by the longitudinal direction and the transverse direction. In the case of operating the palletizing device, both the longitudinal direction and the transverse direction extend horizontally, i.e. parallel to the ground on which the palletizing device is located. The vertical direction extends perpendicularly with respect to the ground, at right angles to the longitudinal direction and at right angles to the transverse direction.

According to one preferred configuration of the invention, each angle between the two sides on which the guide is arranged lies in the range from 1 ° to 89 ° in each case. Particularly preferably, each angle between the two sides provided with the guide means lies in the range from 50 ° to 70 ° in each case. In particular, the lifting device may have a cross section in the form of an equilateral triangle, wherein all said angles are 60 °.

According to one advantageous configuration of the invention, each carriage, which is guided displaceably on the guide, is assigned a separate drive for displacement in the vertical direction. Furthermore, the carriages are advantageously movable independently of one another in the vertical direction.

According to an advantageous development of the invention, the placement device is fixed to a first carriage arranged on the first side of the lifting device and can be moved together with the first carriage in the vertical direction. The placement device defines a transport plane for transporting the layer of articles in the longitudinal direction. The placement device is configured, for example, in the form of a placement belt and includes an endless conveyor belt.

Preferably, in this case, the placement device is movable in the longitudinal direction between a first longitudinal position and a second longitudinal position relative to the first carriage and thus relative to the lifting device.

According to a further advantageous development of the invention, the compression device is fixed to a second carriage arranged on the second side of the lifting device and can be moved together with the second carriage in the vertical direction. In this case, the compression device serves to orient the layer of articles on the transport face of the depositing device.

According to a preferred configuration of the invention, the compression device is in this case fastened to the second carriage by means of a second fastening arm, wherein the second fastening arm passes through a plane defined by the first side face. In this case, a plane defined by the first side faces extends in the vertical direction and the longitudinal direction, wherein the first side faces lie in the plane. Thus, the plane defined by the first side surface extends at right angles to the transverse direction.

Preferably, the compression device has at least one front stop and one rear stop. In this case, the transport face of the placement device is arranged offset in the longitudinal direction with respect to the compression device when the placement device is in the first longitudinal position. When the depositing device is in the second longitudinal position, the layer of articles located on the transport face of the depositing device is arranged in the longitudinal direction between said stops of the compressing device.

According to a further advantageous development of the invention, the transfer device is fixed to a third carriage arranged on a third side of the lifting device and is movable in the vertical direction together with the third carriage. The transfer device defines a transport surface for transporting the layer of articles in the longitudinal direction. The transfer device is configured, for example, in the form of a transfer belt and includes an endless conveyor belt.

According to a preferred configuration of the invention, the transfer device is in this case fastened to the third carriage by a third fastening arm, wherein the third fastening arm passes through a plane defined by the first side face. In this case, a plane defined by the first side faces extends in the vertical direction and the longitudinal direction, wherein the first side faces lie in the plane. Thus, the plane defined by the first side surface extends at right angles to the transverse direction.

Preferably, when the placement device is in the first longitudinal position, the transport face of the placement device is arranged in close proximity to the transport face of the transfer device, so that a layer of articles located on the transport face can be transported onto the transport face in the longitudinal direction. When the placement device is in the second longitudinal position, the transport face of the placement device is arranged offset in the longitudinal direction with respect to the transport face of the transfer device.

A method for operating a palletizing device for placing a layer of objects on a transport aid or on a stack of layers located on a transport aid is also proposed, which method has the features of claim 15. In this case, the palletizing device comprises a lifting device with at least three individual guides, wherein in each case at least one carriage is guided on the at least three guides so as to be movable in the vertical direction. The palletizing device is in particular a palletizing device according to the present invention as described above.

The method according to the invention for operating a palletizing device comprises the following steps.

First, a first carriage on which a placement device is arranged defines a transport plane for transporting a layer of articles in a longitudinal direction, the first carriage being moved in a vertical direction to a predetermined height position. The height position is determined such that the transport surface of the placement device is slightly above the transport aid or the layer stack located thereon. The placement device is configured, for example, in the form of a placement belt and includes an endless conveyor belt.

Likewise, a compression device is arranged on the second carriage for orienting the article layer on the transport surface of the depositing device, the second carriage having at least one front stop and one rear stop, the second carriage being moved in the vertical direction to a predetermined height position. The height position is determined such that the compression device is located above the transport plane of the placement device.

Furthermore, the layer of articles is transferred onto a transfer device which is connected to the third carriage and which defines a transport surface for transporting the layer of articles in the longitudinal direction. The transfer device is configured, for example, in the form of a transfer belt and includes an endless conveyor belt. The layer of articles is conveyed, in particular, by the feed device onto the transport surface of the transfer device.

Subsequently, the third carriage is moved to a predetermined height position. The height position is determined such that the transport surface of the transfer device is at the same height as the transport surface of the placement device.

The layer of articles is then transferred from the transport face of the transfer device onto the transport face of the placement device while the placement device is in a first longitudinal position in which the placement device is disposed immediately adjacent to the transfer device in the longitudinal direction.

The placement device is then moved in the longitudinal direction relative to the first carriage to a second longitudinal position in which the layer of articles located on the transport surface of the placement device is disposed in the longitudinal direction between the stops of the compression device.

For example, the compression device is now located in a height position in which the two stops of the compression device are located above the layer of articles that is located on the transport surface of the placement device. In this case, the compression device is now moved downwards in the vertical direction until the layer of articles located on the transport surface is located at the level of the stop in the vertical direction.

Optionally, the compression device is now in a height position in which the front stop of the compression device is already at the level of the layer of articles that is on the transport face of the placement device. In this case, the rear stop of the compression device is moved from a standby position, in which the rear stop is vertically above the layer of articles, to an operating position, in which the rear stop is vertically at the level of the layer of articles.

The layer of articles on the transport face of the depositing device is now situated between the stops in the longitudinal direction and at the level of the stops in the vertical direction. The placement device is now moved back in the longitudinal direction with respect to the first carriage to the first longitudinal position. In this process, a layer of the article is placed on the transportation aid or on a stack of layers located on the transportation aid.

When the placement device has an endless conveyor belt, the movement of the placement device in the longitudinal direction relative to the first carriage to the first longitudinal position may be synchronized with the circulation of the conveyor belt, so that the placement device is moved out from under the layer of articles.

Detailed Description

Fig. 1 shows a schematic plan view of a palletizing device 10. The palletizing device 10 is located on the ground 12 and is used to place goods, in particular a layer 15 of goods (not shown here), on a layer stack 100 (not shown here), which layer stack 100 is located on a transport aid 105 (not shown here).

The palletizing device 10 comprises a lifting device 20 which extends away from the ground 12 substantially in a vertical direction Z. The vertical direction Z extends at right angles to the ground 12 and at right angles to the longitudinal direction X. The transverse direction Y extends at right angles to the vertical direction Z and at right angles to the longitudinal direction X.

The lifting device 20 is configured in the form of a column and in the present case has three sides, in particular a first side 21, a second side 22 and a third side 23. In this case, the lifting device 20 is configured as a right prism and has a triangular cross section. The first side 21 of the lifting device 20 defines a plane extending in the vertical direction Z and the longitudinal direction X, wherein the first side 21 lies in the plane. Thus, the plane defined by the first side face 21 extends at right angles to the transverse direction Y.

The first guide 41 is provided on the first side 21 of the lifting device 20. On the first guide 41, the first carriage 31 is guided to be movable in the vertical direction Z. A second guide 42 is provided on the second side 22. On the second guide 42, the second carriage 32 is guided to be movable in the vertical direction Z. A third guide 43 is provided on the third side 23. On the third guide 43, the third carriage 33 is guided so as to be movable in the vertical direction Z.

The guide means 41,42,43 are in each case configured, for example, in the form of two mutually spaced-apart guide rails extending in the vertical direction Z. In each case, a separate drive (not shown here) is assigned to each carriage 31,32,33 which can be guided displaceably on the guide devices 41,42,43 for movement in the vertical direction Z. In particular, the carriages 31,32,33 are movable independently of one another in the vertical direction Z.

The placement device 50 is fixed to the first carriage 31. The placement device 50 is movable in the vertical direction Z relative to the lifting device 20 with the first carriage 31. In addition, the placement device 50 is movable in the longitudinal direction X between a first longitudinal position and a second longitudinal position with respect to the first carriage 31 and the lifting device 20. In the illustration shown here, the placement device 50 is in a first longitudinal position.

The depositing device 50 is configured in the form of a depositing belt and comprises an endless conveyor belt 52, the endless conveyor belt 52 defining a transport plane 53 for transporting the layer 15 of articles in the longitudinal direction X. The transport face 53 extends in a plane defined by the longitudinal direction X and the transverse direction Y. The vertical direction Z therefore extends at right angles to the transport surface 53.

The compression device 80 is fixed to the second carriage 32. The pressing device 80 is movable in the vertical direction Z relative to the lifting device 20 with the second carriage 32. The hold-down device 80 is used to orient the layer of articles 15 on the transport surface 53 of the placement device 50. The compression device 80 is fastened to the second carriage 32 by means of a second fastening arm 85. The second fastening arm 85 passes through the plane defined by the first side 21 of the lifting device 20.

The compression device 80 has a front side stopper 81 and a rear side stopper 82. In this case, the transport face 53 of the placement device 50 is arranged offset in the longitudinal direction X with respect to the compression device 80 when the placement device 50 is in the first longitudinal position. When the depositing device 50 is in the second longitudinal position, the layer of articles 15 located on the transport face 53 of the depositing device 50 is arranged in the longitudinal direction between the two stops 81,82 of the compression device 80.

The transfer device 70 is fixed to the third carriage 33. The transfer device 70 is movable in the vertical direction Z relative to the lifting device 20 with the third carriage 33. In this case, the transfer device 70 is fastened to the third carriage 33 by a third fastening arm 75. The third fastening arm 75 passes through the plane defined by the first side 21 of the lifting device 20.

The transfer device 70 is configured in the form of a transfer belt and comprises an endless conveyor belt 72, the endless conveyor belt 72 defining a transport surface 73 for transporting the layer 15 of articles in the longitudinal direction X. The transport surface 73 extends in a plane defined by the longitudinal direction X and the transverse direction Y. The vertical direction Z thus extends at right angles to the transport surface 73.

When the placement device 50 is in the first longitudinal position, the transport face 53 of the placement device 50 is disposed in close proximity to the transport face 73 of the transfer device 70, so that the layer of articles 15 located on the transport face 73 can be transported in the longitudinal direction X onto the transport face 53. When the placement device 50 is in the second longitudinal position, the transport face 53 of the placement device 50 is arranged offset in the longitudinal direction X with respect to the transport face 73 of the transfer device 70.

The first carriage 31, the second carriage 32 and the third carriage 33 are arranged and disposed on the side faces 21,22,23 of the lifting device 20 so as to allow collision-free movement of the carriages 31,32,33 on the guide devices 41,42,43 in the vertical direction Z. A collision of the carriage 31,32,33 with one of the fastening arms 75,85 is also avoided.

As long as the placement device 50 is in the first longitudinal position, a collision of the placement device 50, the transfer device 70 and the compression device 80 with each other or with one of the carriages 31,32,33 or with one of the fastening arms 75,85 can also be avoided. When the placement device 50 is in the second longitudinal position, the placement device 50 may collide with the compression device 80.

Fig. 2 shows an enlargement of a subregion of fig. 1. The three sides 21,22,23 of the lifting device 20 each extend parallel to the vertical direction Z and are oriented obliquely with respect to one another. The second side 22 and the third side 23 enclose a first angle a1 with each other. The third side 23 and the first side 21 enclose a second angle a2 with each other. The first side 21 and the second side 22 enclose a third angle a3 between each other. In this case, the angles a1, a2, A3 between the sides 21,22,23 lie in a plane defined by the longitudinal direction X and the transverse direction Y.

In the present case, the lifting device 20 has a cross section in the form of an equilateral triangle. All angles a1, a2, A3 between the flanks 21,22,23 are therefore exactly 60 °. However, the lifting device 20 may also have some other cross-section. The angles a1, a2, A3 between the three sides 21,22,23 on which the guides 41,42,43 are arranged can be in the range from 1 ° to 89 °. Preferably, each of the angles a1, a2, A3 is in the range of 50 ° to 70 °.

Fig. 3 shows a schematic front view of the palletizing device 10 in fig. 1. The layers of articles 15 are fed to the palletizing device 10 by means of a feeding device 110. In this case, first all the individual goods are combined by the feed device 110 into a stackable product layer 15, and then the product layer 15 thus produced is conveyed further in the longitudinal direction X to the palletizing device 10. A layer of articles 15 is placed by the palletizing device 10 on the stack 100 already on the transport aid 105. The transportation aid 105 is, for example, a pallet and is located below the compression device 80 in the vertical direction Z. A plurality of article layers 15 form a stack 100 on a transport aid 105. In this case, the layer 15 of articles is first transferred by the feeding device 110 onto the transport surface 73 of the transfer device 70.

In the illustration shown here, the transfer device 70 is located at a height position in the vertical direction Z in order to align the transport surface 73 with the feed surface 113 of the feed device 110. The layer of articles 15 has been positioned on the transport surface 73 of the transfer device 70. The placement device 50 is located in a first longitudinal position. The placement device 50 is positioned at such a height that the conveyor belt 52 is slightly above the layer stack 100, said layer stack 100 being positioned on the transport aid 105. The compression device 80 is located at an elevation above the conveyor belt of the placement device 50.

Fig. 4 shows a further schematic front view of the palletizing device 10 in fig. 1. Starting from the situation in fig. 3, the third carriage 33 is now moved together with the transfer device 70 into a height position such that the transport surface 73 is aligned with the transport surface 53 of the placement device 50. The article layer 15 is then transported from the transport surface 73 onto the transport surface 53.

In the illustration shown here, the transfer device 70 is located at a height position in the vertical direction Z such that the transport surface 73 is aligned with the transport surface 53 of the placement device 50. The layer of articles 15 is positioned on the transport surface 53 of the placement device 50. The placement device 50 is located in a first longitudinal position. The placement device 50 is positioned at such a height that the conveyor belt 52 is slightly above the layer stack 100, said layer stack 100 being positioned on the transport aid 105. The compression device 80 is located at an elevation above the conveyor belt 52 of the placement device 50.

Fig. 5 shows a further schematic front view of the palletizing device 10 of fig. 1. Starting from the situation of fig. 4, the placement device 50 is now moved together with the layer of articles 15 into the second longitudinal position. In the second longitudinal position, the transport face 53 of the placement device 50 is arranged directly below the compression device 80. Likewise, the third carriage 33 is moved together with the transfer device 70 to a height position where the conveying surface 73 is aligned with the feeding surface 113 of the feeding device 110.

In this case, the compression means 80 may be located at a height position in which both stops 81,82 are located above the layer of articles 15. In this case, after the depositing means 50 have reached the second longitudinal position, the compression means 80 are moved downwards in the vertical direction Z until the layer of articles 15 is at the level of the two stops 81,82 in the vertical direction.

The compression means 80 may also be located in a height position in which the front stop 81 is already at the level of the layer of articles 15. In this case, the rear side stopper 82 is located at the standby position, in which the rear side stopper 82 is located above the article layer 15 in the vertical direction Z. In this case, after the depositing device 50 has reached the second longitudinal position, the rear stop 82 is moved into the operating position, in which the rear stop 82 is located at the level of the layer of articles 15 in the vertical direction Z.

In the illustration shown here, the transfer device 70 is located at a height position in the vertical direction Z such that the transport surface 73 is aligned with the feed surface 113 of the feed device 110. Already on the feeding surface 113 of the feeding device 110 is another layer of articles 15, which is transferred onto the transport surface 73.

The placement device 50 is located in a second longitudinal position. The placement device 50 is positioned at such a height that the conveyor belt 52 is slightly above the layer stack 100, said layer stack 100 being positioned on the transport aid 105. The compression device 80 is located at an elevation above the conveyor belt 52 of the placement device 50.

The layer of articles 15 is positioned on the transport surface 53 of the placement device 50 and extends into the compression device 80. The layer of articles 15 is located between the stops 81,82 of the compression device 80 in the longitudinal direction X and at the level of the stops 81,82 in the vertical direction Z.

The placement device 50 is now moved back in the longitudinal direction X to the first longitudinal position. In this case, the displacement of the placement device 50 in the longitudinal direction X to the first longitudinal position is synchronized with the circulation of the conveyor belt 52, so that the placement device 50 is moved out from under the layer of articles 15. Thus, the layer of articles 15 is placed on the stack 100 on the transportation aid 105. Thus, the stack 100 is taller than the height of the article layers 15.

Subsequently, the first carriage 31 with the placement device 50 and the second carriage 32 with the compression device 80 are moved upwards in the vertical direction Z from the height of the product layer 15 to the height position described with respect to fig. 3. As shown in fig. 3, a further layer 15 of objects, which is located on the feed surface 113 of the feeder device 110, is conveyed to the palletizing device 10 and is transferred onto the transport surface 73 of the transfer device 70.

When the stack 100 comprises a certain number of article layers 15 and has a certain height, the stack 100 is removed together with the transport aid 105. A further transport aid 105 (e.g. a pallet) is arranged below the compression device 80 and a further layer of articles 15 is placed on the further transport aid 105 and stacked, thus forming a further layer stack 100.

The present invention is not limited to the exemplary embodiments described herein and the aspects highlighted therein. On the contrary, many modifications are possible within the reach of the person skilled in the art, within the scope defined by the claims.
