Description

The present invention relates to an apparatus and a method for forming and handling palletizable layer arrangements according to the features of the independent claims.

The present invention relates to the arrangement of articles, objects or piece goods in palletizable layer arrangements and the handling of corresponding layer arrangements. In particular for the production of layer arrangements each comprising a plurality of bottles and cans.

This can preferably be filled or empty beverage bottles or cans. As a rule, the bottles or cans are guided in lanes and fed to a layer-forming area and arranged there according to the desired layer. The layer formed is then transferred to a pallet.

For example, the patent shows EP 472909 B1 describes an apparatus for forming multiple rows of upstanding round cross-section vessels from which multiple rows layers are subsequently formed. Here, the articles are guided on a conveyor table in parallel lanes to form the rows against a run-up bar. Furthermore, means for pushing the rows of bottles together transversely to the conveying direction are provided in order to eliminate the distance between the rows of bottles.

The disadvantage here is the complex construction with channel guides and the subsequent need to push them together, which makes the device expensive to manufacture. In addition, when the product is changed, the width and number of lanes may have to be adjusted by means of complex conversion work on the device, in order, for example, to also be able to process articles with a smaller cross-sectional area within the device.

The object of the invention consists in bringing articles into a suitable layer arrangement in a simple and time-optimized manner. In particular, the device should be suitable for handling different articles.

The above object is achieved by an apparatus and a method for forming and handling palletizable layer assemblies comprising the features in the independent patent claims. Further advantageous configurations are described by the dependent claims.

The arrays of layers formed by the apparatus and method each comprise a plurality of articles. This can in particular be beverage containers or other containers filled with a fluid content, which preferably have a substantially or at least partially cylindrical or similar shape.

Thus, the articles preferably have a circular base. The articles are particularly preferably formed by cans or bottles, in particular by filled or empty beverage cans or beverage bottles. However, the device can also be used to handle articles with other bases, but the device is not suitable for articles with a square or rectangular base, but rather for articles with a hexagonal base, an octagonal base, an oval or other shaped base, which articles can be brought into a condensed configuration, in which condensed configuration, however, minimal gaps between the articles still exist due to the article shape.

The device is used in particular for the formation of article layers from which articles it is not possible to produce a completely gap-free arrangement due to their circular or circular base area or otherwise non-rectangular base area.

The device comprises a feed device which at least partially protrudes into a preforming area and which feed device is designed to move articles in a transport direction in a random mass flow and to feed them to a layer formation area of the device. In particular, at least part of the feed device is assigned to the preforming area.

The pre-forming area includes at least one means for converting the mass-moving articles into a compacted configuration in which the gaps formed between adjacent articles are minimized.

The condensed arrangement is characterized in particular by the fact that the articles are arranged offset to one another. As a result, the available space is used optimally and the size of the gaps between them, which are mandatory due to the shape of the articles, is minimized. The compacted arrangement is also referred to as a nested arrangement or sphere packing.

The layer formation area of the device comprises at least one handling device for detecting a plurality of articles, which articles are in the compacted array and form a palletizable tier array. The detected layer arrangement is in particular transferred to a pallet.

The handling device is formed, for example, by a robot or the like, which includes a layer gripper. Layer grippers in the form of suction plates are suitable for grasping layer arrangements formed from beverage cans or layer arrangements comprising empty cans that have yet to be filled. On the other hand, gripper heads with a suitable number and arrangement of gripping elements in the form of tulip grippers or the like are suitable for gripping empty or filled bottles.

The method for forming and handling layered arrangements that can be palletised, which can be carried out in particular with the device described above, accordingly provides that the articles are fed in a transport direction in a disordered mass flow, with the articles passing through a pre-forming area in which the articles, which are continuously moved in the transport direction, are arranged in a nested arrangement be transferred. For this purpose, the articles moving in the direction of transport are subjected to an oscillating component of movement, at least in certain areas.

Subsequently, in a layer formation area, the plurality of articles forming a layer arrangement and located in a compacted arrangement are grasped together and conveyed for further handling. In particular, the acquired layer arrangement is palletized, with several layer arrangements being stacked one on top of the other on a pallet. Provision can be made here for an intermediate layer to be arranged between the layer arrangements stacked on top of one another. Such an intermediate layer preferably consists of a flat material, for example a plastic, paper, cardboard or composite material, and is used in particular for stabilization. The use of intermediate layers to stabilize the stack of layers makes sense, especially when palletizing layered arrangements of bottles.

In order to convert the articles into the compacted arrangement, according to a preferred embodiment it is provided that the articles moving in the mass flow are subjected to oscillating movements or shaking movements during the movement in the transport direction.

The oscillating component of movement can be formed, for example, by a component of movement in a horizontal plane or a component of movement in a substantially horizontal plane, the component of movement being applied laterally to the article. The movement component can alternatively or additionally be formed by a vertical movement component, which is also applied to the article from below, for example. The movement component is not limited to a horizontal or vertical alignment, further possibilities that are conceivable and technically realizable for the person skilled in the art are also intended to be covered by the application.

The movement component can be applied to the articles in a continuous and/or regular manner. Both slow and fast movements are possible. As a rule, it is sufficient if only very small movements are applied to the articles in order to generate the desired relative movements of the articles against one another, which are necessary for forming the compacted arrangement.

In particular, the preforming area comprises at least one device suitable for this purpose, which is designed to apply an oscillating movement component or shaking movement to the articles at least in certain areas.

The devices can act from the side and/or from below on at least some of the articles moving in the mass flow in the direction of transport.

A first embodiment of such a device is formed by lateral railings, which laterally delimit the feed device and thus the transport route for the articles. The railing guides are preferably arranged parallel to the transport direction and are designed to be movable. In particular, it is provided that the railing guides are designed to be movable between two end positions arranged parallel to the transport direction. Furthermore, the railing guides are assigned at least one drive means for movement between the two end positions and a control device which is designed to control an oscillating movement of the railing guides, in particular an oscillating movement of the railing guides directed in the opposite direction. The control device can be formed, for example, by the machine control of the device.

According to one embodiment it can be provided that the railing guides are set at an angle to one another. In particular, it can be provided that the railings in the transport direction TR are arranged running towards one another, so that the width of the transport route for the articles in the transport direction tapers, which the Compression of the item arrangement also supported.

The railing guides are preferably designed to be movable transversely to the direction of transport. This means that the railing guides arranged parallel to the direction of transport can be moved back and forth between two end positions arranged parallel to the direction of transport. The same applies to angled railings. In particular, the two railing guides each perform an oscillating movement in opposite directions, i.e. the railing guides move towards or away from each other, respectively.

Due to the oscillating movement of the railing guides, an oscillating movement or shaking movement is applied at least to the outer articles of the mass flow, which is passed on to the articles located further inside in the mass flow. The oscillating movement or shaking movement causes the articles not only to be moved by the feed device in the transport direction, but also to shift against one another with a movement component transversely to the transport direction TR, which leads to the desired compression of the article arrangement.

Furthermore, it is conceivable that the railing guides carry out an oscillating movement in and against the transport direction, as a result of which an oscillating movement or shaking movement is also applied to the articles. The superimposition of oscillating movements in and against the direction of transport and oscillating movements transversely to the direction of transport or at an angle to the direction of transport can advantageously bring about the compression of the articles moved in the direction of transport.

A further embodiment of such a device can provide that it is formed by a vibrating plate arranged at least in some areas below the feed device, which is mechanically operatively connected to the feed device to transmit an oscillating or vibrating movement to the articles fed in the mass flow. This is in particular an oscillating or shaking movement with a vertical movement component that acts on the article from below.

In particular, a combination of two oscillating railing guides arranged opposite one another and arranged to the side of the transport path and a vibrating plate arranged below the transport path can be used to compact the article arrangement. The combination of the different devices can possibly shorten the length of the transport route, since the different oscillating movement components increase the compacting effects and the compaction of the article arrangement can thus be achieved more quickly.

Furthermore, it is provided that the layer formation area comprises a stop element which extends transversely to the transport direction and is preferably equipped with a rear side which is contoured in the transport direction. The contouring or profiling of the stop element in particular reproduces the contour of the foremost row of articles in a layered arrangement formed from a plurality of rows of articles. In particular, the series of articles are shifted against each other.

The stream of articles, which has been converted into an orderly, compacted arrangement in the pre-forming area, is guided against the stop element and the articles accumulate behind the stop element in a compacted arrangement. Here, the desired position of the articles in the front row of the layer arrangement is determined by the profiling of the stop element, so that the layer arrangement can subsequently be detected correctly and precisely by the handling device and transferred to the pallet.

After a complete layer arrangement has passed into the layer formation area, a retaining element in the form of a stop bar or similar is lowered onto the directly following articles, at least for a short time. The stop bar preferably extends perpendicularly to the direction of transport across the entire transport path for the articles and presses from above onto the articles directly following the layered arrangement. As a result, the movement of these articles is at least briefly decelerated and/or stopped and a distance is formed from the articles forming the layered arrangement.

In particular, the retaining element has the effect that the dynamic pressure of the subsequent articles on the articles forming a layered arrangement is reduced. If necessary, provision can also be made in this context for the transport of the articles in the pre-forming area and, if necessary, the supply of articles to the pre-forming area to be stopped completely for a short time.

After the layer arrangement has been detected by the handling device, the stop bar is raised again so that the articles temporarily fixed by the stop bar and subsequent articles can be moved further in the transport direction into the layer formation area.

Furthermore, it can be provided that a second stop element is assigned to the preforming area. This second stop element also preferably extends across the entire width of the transport path transversely to the transport direction. The second stop element preferably also has a rear side which is profiled and simulates the contour of the front row of articles in a layered arrangement. This stop element is necessary in particular when the device is first filled and/or operated for the first time, in order to produce the contour of the front row of the articles placed in a compacted arrangement.

It may also be necessary at a later point in time to produce and/or ensure the contour of the front row of the articles placed in a compacted arrangement if, for example, too few articles are being conveyed. In this case, there is a risk that the compacted arrangement will loosen up again due to a lack of lateral pressure.

So that the second stop element does not disturb the flow of articles when not in use, it is provided that the second stop element can be removed from the transport path of the articles with an upward movement or with a lateral pivoting movement or the like and is only arranged within the transport path if necessary .

The device is also suitable for different articles, since only the stop elements may have to be exchanged when there is a product change in order to adapt the device to the new product. It may be necessary to adapt the layer gripper of the handling device to the new product.

It should be expressly mentioned at this point that all aspects and design variants that have been explained in connection with the device according to the invention equally relate to or can be partial aspects of the method according to the invention. Therefore, if certain aspects and/or connections and/or effects are mentioned at one point in the description or also in the definition of claims for the device according to the invention, this applies equally to the method according to the invention. The same applies in reverse, so that all aspects and design variants that have been explained in connection with the method according to the invention equally relate to or can be partial aspects of the device according to the invention. Therefore, if certain aspects and/or connections and/or effects are mentioned at one point in the description or also in the claim definitions for the method according to the invention, this applies equally to the device according to the invention.

Identical reference symbols are used for elements of the invention that are the same or have the same effect. Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures that are necessary for the description of the respective figure. The illustrated embodiments only represent examples of how the device according to the invention or the method according to the invention can be designed and do not represent any final limitation.

The 1 shows a highly schematic plan view of a first embodiment of a device 1 for forming and handling layer arrangements 100 that can be palletized.

The device 1 comprises a feed device 2 which is designed to move articles 101 in a transport direction TR in the disordered mass flow MS.

The device 1 further comprises a preforming area 3 and a layer formation area 4.

In the pre-formation area 3, the items supplied in the random mass flow MS are kel 101 is converted into a compacted arrangement vA, in which gaps L between adjacent, in particular adjacent, articles 101 are reduced.

The articles 101 handled in the device 1 generally have an essentially or at least partially cylindrical shape. This means that the articles 101 preferably have a circular base area. The articles 101 are particularly preferably formed by cans 102 or bottles, in particular beverage cans or beverage bottles. The device 1 can also be used to handle items 101 with other bases, but the device 1 is not suitable for items with a square or rectangular base, but rather for items with a hexagonal base, an octagonal base, an oval or other shaped base. which articles 101 can be brought into a condensed arrangement vA.

The compressed arrangement vA is characterized in that the articles 101 are arranged offset from one another, with the size of the gaps L that necessarily exist between these due to the shape of the articles 101 being minimized. Minimal gaps L(M) are thus formed between the articles 101 in the compressed arrangement vA. The minimum results automatically due to the base area of the articles 101, since it is not possible, particularly in the case of articles 101 with a circular or circular-like base area, to produce a completely gap-free arrangement.

The condensed vA arrangement is also referred to as a nested arrangement or sphere packing.

In order to convert the articles 101 into the compacted arrangement vA, the preforming area 3 comprises at least one device 10 suitable for this purpose, which is designed to apply an oscillating movement component to the articles 101 at least in certain areas.

The oscillating component of movement can be formed, for example, by a component of movement in a horizontal plane or in a substantially horizontal plane, which is applied laterally to the article 101 . The movement component can alternatively or additionally be formed by a vertical movement component, which is also applied to the article 101 from below, for example.

The movement component can be applied in a continuous and/or regular manner. Slow or fast movements are possible here. As a rule, only very small movements are applied to the articles 101.

Possible embodiments for corresponding devices 10 are in connection with the 3 and 4 described.

The articles 101 in a compacted arrangement vA are fed to the layer formation area 4 in which an article layer or layer arrangement 100 is gripped by a corresponding handling device 5 and transferred to a pallet 20 . In particular, an article layer or layer arrangement 100 comprises a plurality of articles 101 in a compacted arrangement vA, which plurality of articles 101 forms a layer arrangement 100 that can be palletized.

The handling device 5 is formed, for example, by a robot 6 which has a layer gripper 7 (cf 2 ) includes. Layer grippers 7 in the form of suction plates are suitable for grasping layer arrangements 100 formed from beverage cans 102 or for grasping layer arrangements 100 comprising empty cans 102 that still have to be filled. On the other hand, gripper heads with a suitable number and arrangement of gripping elements in the form of tulip grippers or the like are suitable for gripping empty or filled bottles.

The layer formation area 4 has a stop element 8 which extends transversely to the transport direction TR of the articles 101 and against which the articles 101 located in an orderly, compacted arrangement vA are guided. The stop element 8 has in particular a profile 9 which simulates the contour of the front row of the articles 101 of the layer arrangement 100 . In particular, this determines the desired position of the articles 101 in the front row of the layer arrangement 100 within the layer formation area 4, so that the layer arrangement 100 can be correctly and precisely grasped by the handling device 5 and transferred to the pallet 20 or otherwise handled.

The stream of articles compressed within the pre-forming area 3 is driven against the stop element 8 and the articles 101 accumulate behind it in a compressed arrangement vA. After a complete layer arrangement 100 has passed into the layer formation area 4, a retaining element in the form of a stop bar 16 is lowered at least briefly onto the directly following article 101, which stop bar 16 extends perpendicularly to the transport direction TR across the transport route TS for the articles 101 extends in the preforming area 3 and presses from above onto the article 101 directly following the layer arrangement 100 .

As a result, the movement of these articles 101 is decelerated at least briefly and a distance A from the articles 101 forming the layer arrangement 100 is formed. The stop bar 16 has the effect, in particular, that the dynamic pressure of the following articles 101 on the articles 101 forming a layer arrangement 100 is reduced. If necessary, it can also be provided in this connection that the transport of the following articles 101 in the pre-forming area 3 and, if necessary, the supply of articles 101 to the pre-forming area 3 are stopped completely for a short time.

The detected layer arrangement 100 is placed on a waiting pallet 20 or on an upper article layer of layer arrangements 100 already stacked on a pallet 20 . Provision can be made here for an intermediate layer made of a flat material, for example a plastic, paper, cardboard or composite material, to be arranged between the layer arrangements 100 stacked on top of one another on the pallet 20 .

After the layer arrangement has been detected, the stop bar 16 is raised again, so that the articles 101 briefly fixed by the stop bar 16 and subsequent articles are moved further into the layer formation area 4 in the transport direction TR.

The 2 shows a schematic and side view of the formation of a layer arrangement 100 within a device 1. The articles 101, in particular cans 102, run from the preforming area 3 in a compacted arrangement vA in the transport direction TR into the layer formation area 4 and against the stop element 8. If all one Once the articles 101 forming the layer assembly 100 have entered the layer forming area 4, the drive of the feed device 2 is switched off. In addition, a stop bar 16 is pressed from above onto at least the articles 101 that follow the layer arrangement 100 in the first place, in order to prevent them from also crossing over into the layer formation area 4, for example due to the dynamic pressure of the following articles 101.

In this case, an at least slight distance A is preferably formed between the articles 101 of the layer arrangement 100 within the layer formation area 4 and the articles 101 following in the preforming area 3 . In particular, it can be provided that the feed device 2 does not extend into the layer formation area 4, but that this has its own transport device (not shown), which is formed, for example, by a conveyor belt aligned with the feed device 2 and which can preferably be controlled independently.

The layer arrangement 100 can now be gripped by the handling device 5 and transferred to a pallet 20 . In particular, a layer arrangement 100 formed from cans 102 is gripped by a layer gripper 7 designed as a suction plate. In contrast, a layer arrangement 100 formed from bottles is preferably gripped by a layer gripper 7 comprising a plurality of tulip grippers or the like. To set down the layer arrangement 100 formed from cans 102, the vacuum of the suction plate is released again and the cans 102 are thus released.

The schematic view of 3 shows a second embodiment of a device 1 for forming and handling palletizable layer arrangements 100, while the 4 an enlarged detail of the device 1 according to 3 clarified.

The device 1 shown here also comprises a feed device 2, a preforming area 3 and a layer formation area 4.

Possible embodiments of devices 10 for producing the condensing arrangement of the articles (not shown) are described in more detail below. In particular, these are devices 10 which are designed to apply oscillating movements or shaking movements to the articles (not shown) fed in the disordered mass flow.

In a first embodiment, the device 10 is formed by railings 11 which delimit the feed device 2 laterally. These are preferably railing guides 11, which are arranged parallel to the transport direction TR of the articles and are designed to be movable.

According to one embodiment, it can be provided that the railing guides 11 are set at an angle to one another. In particular, provision can be made for the railing guides 11 to run towards one another in the transport direction TR, so that the width of the transport route TS for the articles narrows in the transport direction TR, which additionally supports the compression of the flow of articles.

The railing guides 11 are preferably designed to be movable transversely to the transport direction TR. That is to say, the railing guides 11 arranged parallel to the transport direction TR can be placed between two parallel to the transport direction TR ordered end positions are moved back and forth. The same applies to angled railings 11.

For this purpose, at least one drive means 12 is assigned to the railing guides 11, in particular a motor 13, which is designed to drive the oscillating movement of the railing guides 11 transversely to the transport direction TR. In particular, the two rail guides 11 each perform an oscillating movement in opposite directions, i.e. the rail guides 11 move towards or away from each other, respectively. This is indicated, for example, by the double arrow perpendicular to the transport direction TR.

The movement of the railing guides 11 causes an oscillating movement or shaking movement to be applied to the outer articles of the mass flow, which movement is passed on through the outer articles to the articles located further inside the mass flow. The oscillating movement or shaking movement causes the articles not only to be moved by the feed device 2 in the transport direction TR, but also to move against one another with a movement component transversely to the transport direction TR, which leads to the desired compression in the article flow.

Furthermore, it is conceivable that the railing guides 11 perform an oscillating movement in and against the transport direction TR, which also causes an oscillating movement or shaking movement to be applied to the articles. The superimposition of oscillating movements in and against the transport direction TR as well as oscillating movements transverse to the transport direction TR can advantageously bring about the compression of the articles moving in the transport direction TR.

The drive means 12 is connected in particular to a control device 15 of the device 1, which control device 15 is designed, among other things, to control the oscillating movement of the railing guides 11, in particular an oppositely directed oscillating movement of the railing guides 11 transversely to the transport direction TR.

Alternatively or additionally, it can be provided that a vibrating plate 14 is arranged at least in some areas below the feed device 2, which is mechanically operatively connected to the feed device 2 in order to apply an oscillating or vibrating movement to the articles fed in the mass flow. This is in particular an oscillating or shaking movement with a vertical movement component that acts on the article from below.

Furthermore, in the illustrated embodiment of the device 1, a further, second stop element 17 is provided in the preforming area 3, which also has a profile 18, which profile 18 simulates the contour of the front row of articles in a layer arrangement. This stop element 17 is necessary in particular when the device 1 is first filled and/or operated for the first time, in order to produce the contour of the front row of the articles placed in a compacted arrangement.

It may also be necessary at a later point in time to produce the contour of the front row of the articles placed in a compacted arrangement if, for example, too few articles are being conveyed. In this case, there is a risk that the compacted arrangement will loosen up again due to a lack of lateral pressure.

For this reason it is advantageous that the stop element 17 can be removed from the transport path TS of the article with an upward movement or with a lateral pivoting motion or the like and is only arranged within the transport path TS when required.

The schematic representation of 5 Figure 12 shows a third embodiment of an apparatus for forming and handling palletizable layer assemblies. In this case, two preforming areas 3a, 3b and two layer formation areas 4a, 4b are operated alternately by a robot 6, ie two product lines are processed in parallel with only one handling device 5. This is particularly advantageous if the handling device 5 can grasp the layer arrangements and place them on a respective pallet 20a, 20b faster than sufficient articles for new layer arrangements can be transported via a single feed device 2 and brought into a compacted arrangement in the preforming area 3 .

The 6 shows schematically a further possibility of layer formation. Here, the articles 101, in particular cans 102, run within a layer formation area 4 in the mass flow MS against a straight or profiled contact beam 19, which extends transversely to the transport direction TR. A compacted arrangement vA is formed as a result of the articles 101 squeezing in and due to the back pressure of the following articles 101 .

When the articles 101 forming a layer arrangement 100 have completely passed into the layer formation area 4, the drive of the feed device 2 is switched off and the further feed of articles 101 is thus stopped. In the present case, the layer gripper 7 is designed as a gripper head 21 with retaining rakes 22 and movable clamping elements 23 . One of the movable clamping members 23a grips the front row of articles of the tier assembly 100, while the other movable clamping member 23b is inserted behind the rear row of articles of the tier assembly 100. Furthermore, the retaining rake 22 introduced together with the rear movable clamping element 23b is located between this rear movable clamping element 23b and the foremost following article 101 or row of articles.

The gripper head 21 is designed in such a way that a twisting movement can be carried out within the gripper head 21, by means of which the layer arrangement 101 is pushed together with the contact beam 19 in the transport direction TR. In particular, the movable clamping elements 23, 23a, 23b are moved together and synchronously in the transport direction TR, while the retaining rake 22 remains in its position. A distance A is thus formed between the articles 101 forming the layer arrangement 100 and the following articles 101, which enables the layer arrangement 100 to be easily grasped and moved to a desired new position, for example on a pallet (not shown).

In particular, the suction plate of the gripper head 21 is activated for this purpose, which sucks in the articles 101 of the layer arrangement 100, so that the entire layer arrangement 100 can be lifted and handled.

If necessary, it can be provided that the layer formation area 4 has a preforming area (not shown) - as it is in connection with the 1 until 5 was previously described - is prior.

The embodiments, examples and variants of the preceding paragraphs, the claims or the following description and figures, including their different views or respective individual features, can be used independently of one another or in any combination.
