Description

[0001] The invention relates to a provision device for components in a production line, a production line for a motor vehicle or a motor vehicle component, and a method for providing components in a production line.

[0002] Production lines for motor vehicles and / or motor vehicle components are familiar from industrial practice. Such production lines comprise multiple production stations at which components of the motor vehicle or motor vehicle component are assembled. If components are not delivered to the respective production station on time, delays in the production line can occur. Furthermore, the removal of empty component containers via the same delivery route leads to delays in the process. Furthermore, the delivery of components sometimes introduces dirt into the line production.

[0003] US 2023 / 0 249 910 A1 discloses a method for operating a storage facility, in which goods are brought into the storage facility in a delivery container at a goods receiving area, removed from the delivery container, temporarily stored, and removed from the storage facility in a predetermined sequence in a delivery container at a goods dispatch area. The goods are transferred from the delivery container into a stackable packaging unit, and the packaging unit is temporarily stored in a block storage facility.

[0004] DE 103 08 680 A1 discloses a system for the disposal of cyclically generated workpieces. The system has a horizontal conveyor for the cyclically advancing the workpieces, which are transported to a removal station at the end of the horizontal conveyor. From there, the workpieces are removed and placed in workpiece carriers at a loading station. In order to adapt the disposal of the workpieces to their cyclically produced production process, a vertically movable lifting device with two platforms arranged one above the other for receiving the workpiece carriers is arranged near the removal station of the horizontal conveyor. The loading station is located opposite the removal station on the working level of the horizontal conveyor and can be approached from either of the two platforms by raising or lowering the lifting device by the platform distance.

[0005] Furthermore, DE 10 2009 021 467 A1 discloses a storage system with at least one storage unit which has a horizontally extending storage level and an associated transport level located below this storage level and extending horizontally, wherein the storage level comprises receiving locations which are designed to receive goods to be stored, wherein at least one transport device is present which is movable in the transport level below the receiving locations along at least two horizontal axes, and wherein at least one lifting device is provided by means of which goods can be moved vertically from the transport device into the storage level.

[0006] Based on this, the present invention is based on the object of at least partially overcoming the disadvantages known from the prior art. The features of the invention arise from the independent claims, for which advantageous embodiments are presented in the dependent claims. The features of the claims can be combined in any technically reasonable manner, whereby the explanations from the following description and features from the figures, which comprise additional embodiments of the invention, can also be consulted for this purpose.

[0007] The invention relates to a provision device for components in a production line with a vertical storage direction and a feed direction arranged orthogonally thereto, comprising at least the following components: - a receiving space for receiving an industrial truck loaded with at least one stackable blister; - a storage section for holding a plurality of the stackable blisters stacked along the storage direction; - a removal area for providing one of the stackable blisters so that at least one component can be removed from this stackable blister; and - a conveying mechanism configured to convey the at least one stackable blister from the industrial truck as part of the stackable blisters stacked in the storage section along the storage direction to an upper end of the storage section.

[0008] Unless explicitly stated otherwise, ordinal numbers used in the preceding and following descriptions serve only to clearly distinguish them and do not reflect the order or ranking of the designated components. An ordinal number greater than one does not necessarily imply that another such component must be present.

[0009] Here, a provision device for components on a production line is proposed. Such a provision device is designed to receive stackable blisters, temporarily store them, and present them at a removal area for removal. Such stackable blisters are open, preferably vertically upwards. Each stackable blister is suitable for receiving at least one component, preferably a plurality of components. Components can be removed from the stackable blister, for example, upwards through the opening of the blister. For example, the stackable blisters are boxes or trays. For example, the stackable blisters are made of plastic or metal.

[0010] For example, a plurality of components can be accommodated in each of the stackable blisters. For example, for stable stackability, the blisters have a bottom side that forms a complementary supporting negative to the top side of the blister.

[0011] For example, the blisters each have several subdivisions, each of which is designed to hold one component.

[0012] For the following description, a storage direction vertical within the Earth's gravitational field, a feed direction orthogonal to it, and a conveying direction, preferably orthogonal to the feed direction and storage direction, are defined. When the terms "above" or "below" are used below, these refer to the general usage in relation to the Earth's gravitational field.

[0013] During operation, the stackable blisters are fed into the production line along the feed direction, the stackable blisters are temporarily stored in the supply device along the storage direction, and a motor vehicle or motor vehicle component to be assembled is conveyed through the production line along the conveying direction.

[0014] The supply device has at least one receiving space, a storage section, a removal area and a conveying mechanism.

[0015] The receiving space is designed to accommodate one of the industrial trucks at a time. In other words, the receiving space has an access opening through which an industrial truck can be driven into the receiving space. The receiving space is preferably designed such that the industrial truck can be driven into and out of the receiving space along the feed direction.

[0016] The storage section is designed to accommodate a plurality of stackable blisters in a stacked manner, i.e., as a blister stack. The stackable blisters can thus be temporarily stored in the storage section, preventing delays in making the stackable blisters available for component removal.

[0017] The stackable blisters are thus stacked along the storage direction in the storage section during operation.

[0018] The removal area is designed to accommodate a stackable blister, preferably exactly one stackable blister. A stackable blister located in the removal area is therefore preferably separated from the stacked blisters in the storage section.

[0019] Preferably, the removal area is arranged and designed such that the at least one component arranged in the stackable blister can be particularly easily removed from the stackable blister for assembly and / or processing at the corresponding production station of the production line.

[0020] The conveying mechanism is designed to convey the at least one stackable blister, which is transported on the industrial truck into the receiving space, from the industrial truck along the storage direction. Preferably, the conveying mechanism is designed to lift the at least one stackable blister from the industrial truck. Such an industrial truck is preferably designed such that the stackable blisters are arranged on it from above, along the storage direction. Alternatively or additionally, the conveying mechanism is designed to remove the stackable blisters from or from the industrial truck by other means.

[0021] Preferably, the supply device and / or the production line has a partition wall to a transport area in which the industrial trucks operate. The partition wall is, for example, penetrated by the access opening of the receiving space. For example, the access opening is sealed against dirt, for example, by means of an openable gate or slats, for example, made of plastic or rubber.

[0022] The proposed staging device enables efficient staging of the stackable blisters and thus the components on the production line. Furthermore, it prevents dirt from entering the production line area from a transport area where industrial trucks operate.

[0023] It is further proposed in an advantageous embodiment of the provision device that the removal area is arranged offset from the storage section along the feed direction, and that the provision device has a delivery mechanism which is designed to move an uppermost one of the stackable blisters held in the storage section from the storage section along the feed direction into the removal area.

[0024] The storage section is arranged above the receiving space along the storage direction. The removal area is offset from the storage section along the feed direction.

[0025] The delivery mechanism is designed to move an uppermost one of the stacked blisters held in the storage section from the storage section along the feed direction into the removal area.

[0026] It is further proposed in an advantageous embodiment of the provision device that the delivery mechanism comprises a sliding device and / or a spring mechanism.

[0027] According to this embodiment, the delivery mechanism comprises a sliding device and / or a spring mechanism.

[0028] The sliding device is, for example, a rail or plate inclined in the earth's gravity field, over which the topmost stackable blister slides from the storage section, for example, driven by gravity and / or by the spring mechanism in the feed direction into the removal area.

[0029] Preferably, the stackable blisters are guided horizontally in the storage section, i.e., orthogonally to the storage direction. For example, the guide of the stackable blisters in the feed direction ends at the upper end of the storage section such that the topmost stackable blister is released in the feed direction and can thus be pushed down from the stacked blisters.

[0030] For example, the removal area and the storage section are arranged and / or designed in such a way that a movement of the next uppermost blister into the removal area can be blocked by direct contact between the blister in the removal area and the uppermost stackable blister until the stackable blister has been removed from the removal area.

[0031] Alternatively or additionally, a blocking mechanism is provided by means of which the release of the removal area can be detected, wherein when the removal area becomes free, a blocking element of the blocking mechanism releases the advancement of the next stackable blister into the removal area and / or initiates the advancement by means of a pushing unit.

[0032] It is further proposed in an advantageous embodiment of the provision device that a removal unit, preferably a robot arm, for removing the at least one component from the stackable blister in the removal area.

[0033] The removal unit proposed here is designed to remove the at least one component from the stackable blister located in the removal area. Such a removal unit comprises, for example, a robot arm, which is preferably movable at least along the feed direction in order to introduce the at least one component into the production line.

[0034] It is further proposed in an advantageous embodiment of the provision device that the provision device has a return section by means of which the stackable blisters can be returned along the storage direction to an industrial truck.

[0035] According to this embodiment, the supply device now has a return section. By means of the return section, the emptied stackable blisters can be returned along the storage direction to an industrial truck after the components have been removed from the stackable blisters, i.e., the blisters have been emptied.

[0036] The return section is preferably arranged below the removal area along the storage direction. The return section therefore preferably extends parallel to the storage section and particularly preferably adjacent to it. The emptied blisters are preferably conveyed through the return section by gravity. For example, the emptied stackable blisters are braked by friction and / or a spring mechanism to prevent noise emissions and / or damage to the blisters.

[0037] For example, a plurality of emptied stackable blisters can be temporarily stored, preferably stacked, in the return section. Thus, several blisters can be emptied one after the other in the removal area without a forklift truck having to pick up the emptied stackable blisters in the meantime.

[0038] For example, a blocking mechanism is arranged at a lower end of the return section, which blocks the emptied stackable blisters when no ready-to-receive industrial truck is available in the receiving space. Alternatively or additionally, the blocking mechanism comprises a pusher element by means of which the emptied stackable blisters can be pushed from the return section onto the industrial truck.

[0039] For example, this blocking mechanism is triggered by the transfer of loaded stackable blister packs, which were delivered by the industrial truck, into the storage area. Alternatively or additionally, the blocking mechanism is triggered by an empty industrial truck entering the receiving area or a specific section of the receiving area.

[0040] For example, the section of the receiving space in which loaded stackable blisters are transferred from the industrial truck to the storage section and the section in which the emptied stackable blisters are returned are the same section. In such an embodiment, the emptied stackable blisters are pushed onto the industrial truck in the opposite direction to the feed direction during return from the return section to the industrial truck, for example, by means of the blocking mechanism.

[0041] Alternatively, the receiving space extends in the feed direction, for example, under the return section, so that an industrial truck can be driven under the return section to return the emptied stackable blisters.

[0042] It is further proposed in an advantageous embodiment of the provision device that the return section is arranged offset from the storage section along the direction opposite to the feed direction, and the delivery mechanism is designed to convey the stackable blisters from the removal area into the return section opposite to the feed direction.

[0043] According to this embodiment, the return section is arranged upstream of the storage section along the feed direction. For example, the removal area in this embodiment is arranged above the receiving space, i.e., aligned with the receiving space along the feed direction. After the component has been removed from the stackable blister, the stackable blister can be conveyed into the return section, for example, by means of the feed mechanism, counter to the feed direction.

[0044] It is further proposed in an advantageous embodiment of the provision device that the conveying mechanism is designed to exert a conveying force directed along the storage direction exclusively on the lowest of the blisters stacked in the storage section.

[0045] The conveying mechanism proposed here is designed to exert a conveying force exclusively on a lowermost stackable blister pack arranged in the storage section. The blister packs stored above the lowermost stackable blister pack in the storage section are pushed upward by the lowermost stackable blister pack.

[0046] For example, the conveying mechanism has a spring mechanism for this purpose. For example, the spring mechanism comprises at least two pressure elements. For example, the pressure elements are arranged on opposite sides, preferably opposite one another along the conveying direction. Such pressure elements are designed to transfer the conveying force to the bottommost blister. For example, the pressure elements are beveled at a front end with respect to the feed direction, so that stackable blisters arriving by means of an industrial truck can be pushed between the previously bottommost stackable blister in the storage section and the pressure elements. For this purpose, the stackable blisters have, for example, folds which protrude outwards from the stackable blisters and on which the pressure elements can be supported.

[0047] For example, the storage section has retaining elements. The retaining elements, for example, allow movement of the stackable blisters along the conveying direction and prevent movement of the stackable blisters against the conveying direction; for example, the retaining elements are wedges or hooks. The retaining elements are preferably movable, so that they are pushed outward by an upwardly pushed stackable blister and, after passing the blister, spring back or pivot, thus preventing the blister from sliding backward, similar to a door frame.

[0048] For example, the conveying mechanism has a belt conveyor element by means of which the stackable blisters can be conveyed, similar to a paternoster.

[0049] The embodiment of the provision device proposed here is particularly simple and cost-effective to implement.

[0050] According to a further aspect, a production line for a motor vehicle or a motor vehicle component is proposed, comprising a plurality of production stations for producing a motor vehicle or a motor vehicle component, and a plurality of industrial trucks for receiving and transporting at least one stackable blister, wherein at least one of the production stations has a provision device according to an embodiment according to the above description.

[0051] A production line for motor vehicles and / or motor vehicle components is proposed here. Reference is made to the above description, which already explains possible embodiments and features of such a production line. Such a production line comprises at least a plurality of production stations, a plurality of industrial trucks, and a plurality of stackable blister packs, with reference also being made to the respective embodiments and features explained in the above description.

[0052] The production stations are each designed to perform one or more process steps of a manufacturing process for the motor vehicle or motor vehicle component. For example, individual components are assembled or the current intermediate product is processed or inspected.

[0053] The industrial trucks are each designed to pick up and transport at least one stackable blister pack, preferably a plurality of stackable blister packs. Preferably, the stackable blister packs are stacked on the industrial truck. Preferably, each stackable blister pack contains exclusively components for a specific production station, preferably all components required at that production station.

[0054] At least one production station, preferably several production stations, have a provision device according to the above description.

[0055] According to a further aspect, a method for providing components in a production line is proposed, wherein the method is carried out with a provision device according to an embodiment as described above and at least the following steps are carried out in the order mentioned: a. by means of industrial trucks, transporting stackable blisters containing components; b. Driving the industrial truck into the receiving area; c1. by means of the conveying mechanism, removing at least one blister from the industrial truck and inserting the at least one blister into a blister stack in the storage section; c2. Holding and conveying along the storage direction a plurality of stacked blisters in or through the storage section; d. by means of the feed mechanism, transferring the topmost stackable blister from the storage section to the removal area in the feed direction; e. removing the at least one component from the transferred stackable blister; f. by means of the return section, transporting the emptied stackable blister pack in the opposite direction to the storage direction; and g. Feeding the emptied stackable blister pack into the industrial truck.

[0056] A method for providing components to a production line is proposed here. The proposed method comprises at least steps a. to g.

[0057] In step a, the stackable blisters containing components are transported by the industrial trucks. Preferably, several stackable blisters are stacked on the top side of the respective industrial truck.

[0058] In step b., the industrial truck is driven into a receiving space of a provision device according to the above description.

[0059] In step c1, the at least one stackable blister is removed from the industrial truck by means of the conveyor mechanism.

[0060] By means of the conveying mechanism, the at least one stackable blister is then conveyed, preferably in a blister stack, through the storage section and thus temporarily stored as a buffer in the storage section.

[0061] In step d., the top stackable blister from the blister stack in the storage section is transferred to the removal area by means of the delivery mechanism.

[0062] In step e., for example by means of the removal unit, the at least one component is removed from the blister in the removal area and fed to the line production.

[0063] In step f, the emptied stackable blister is transported by the return section in the opposite direction to the storage direction. Preferably, the emptied stackable blister is guided by the return section and conveyed by gravity.

[0064] In step g., the emptied stackable blister is fed to a forklift truck and transported away.

[0065] The invention described above is explained in detail below against the relevant technical background with reference to the accompanying drawings, which show preferred embodiments. The invention is in no way limited by the purely schematic drawings, whereby it should be noted that the drawings are not to scale and are not suitable for defining proportions. It is shown in Fig. 1: a side view of a provision device in a schematic view; Fig. 2: a plan view of a production line with supply devices according to Fig. 1 in a schematic view; and Fig. 3: a flowchart of a method for providing components to a production line according to Fig. 2.

[0066] In Fig. 1 is a side view of a provision device 1 shown in a schematic view.

[0067] The provision device 1 is explained below with reference to a storage direction 17, a feed direction 18 arranged orthogonally thereto, and a conveying direction 19 arranged orthogonally to the storage direction 17 and the feed direction 18. As shown, the storage direction 17 is arranged vertically from bottom to top, thus running along the Earth's gravitational field. The feed direction 18 is arranged from left to right, as shown, and the conveying direction 19 is arranged in the viewing direction.

[0068] The supply device 1 has a receiving space 3, a storage section 9, a removal area 10 and a return section 13.

[0069] By means of an industrial truck 8, several stackable blisters 4, each equipped with components (not shown here), are moved into the receiving space 3. The stackable blisters 4, as shown three stackable blisters 4, are stacked on top of each other and rest on the industrial truck 8 from above.

[0070] By means of a conveyor mechanism (not shown here), the stackable blisters 4 in the receiving space 3 can be removed from the industrial truck 8 and fed to the storage section 9. In the storage section 9, the stackable blisters 4 can be temporarily stored, in other words, buffered, so that a sufficient supply of the components with which the stackable blisters 4 are equipped is always guaranteed for the production line 2.

[0071] In the storage section 9, the stackable blisters 4 are stacked to form a blister stack 15. As a blister stack 15, the stackable blisters 4 are conveyed from bottom to top along the storage direction 17. The stackable blisters 4 removed by the industrial truck 8 are inserted from below into the blister stack 15 in the storage section 9. The blister stack 15 is conveyed or pushed to an upper end of the storage section 9. Thus, the topmost stackable blister 4, 5 of the blister stack 15 is always in a position in which it can be pushed over into the removal area 10 when the latter is free or released.As shown, the uppermost stackable blister 4,5 is located along the storage direction 17 at the same height as the removal area 10, i.e. the lower edge of the uppermost stackable blister 4,5 is arranged at the same height or higher than a bottom side of the removal area 10.

[0072] By means of a feed mechanism (not shown here), the uppermost stackable blister 4, 5 can be transferred from the storage section 9 into the removal area 10. The uppermost stackable blister 4, 5 is thus moved along the feed direction 18 from left to right as shown.

[0073] In the removal area 10, the components with which the blister 4 (not shown here) is equipped can be removed from the blister 4, for example with a removal unit 11 (see Fig. 2).

[0074] The emptied stackable blister pack 4, 7, from which the components were removed, can be lowered through a return section 13 in the opposite direction to the storage direction 17. This is achieved, for example, by gravity. For example, the emptied stackable blister packs 4, 7 are braked by a guide 16 for the emptied stackable blister packs 4, 7.

[0075] As shown, three empty stackable blister packs 4, 7 are temporarily stored or buffered at a lower end of the return section 13. These can be transported away, for example, by means of the industrial truck 8 after the loaded stackable blister packs 4 have been removed from the industrial truck 8.

[0076] For this purpose, the emptied stackable blisters 4, 7 are conveyed counter to the feed direction 18 from right to left as shown into the receiving space 3 and onto the industrial truck 8.

[0077] In Fig. 2 is a plan view of a production line 2 with supply devices 1 according to Fig. 1 in a schematic view. The production line 2 is designed for manufacturing a motor vehicle or a motor vehicle component. A corresponding intermediate product of the motor vehicle or motor vehicle component can be conveyed along the conveying direction 19 through the production line 2.

[0078] The production line 2 comprises several production stations 14, four of which are shown in the illustrated section of the production line 2. Accordingly, the intermediate product is conveyed along the conveying direction 19 from production station 14 to production station 14.

[0079] In order to supply the production stations 14 with the required components for the respective process steps, the supply devices 1 of the production stations 14 can be approached by means of industrial trucks 8. The components are, as already described with regard to Fig. 1, transported by means of industrial trucks 8 in stackable blisters 4.

[0080] By means of the provision devices 1, the blisters 4 can be provided in removal areas 10, where the components can be removed from the blisters 4 by means of removal units 11. As shown, the removal units 11 are designed as robot arms 12.

[0081] In Fig. 3 is a flowchart of a method for providing components on a production line 2 according to Fig. 2 shown.

[0082] In such a method, in a step a. the stackable blisters 4 are transported by means of the industrial trucks 8.

[0083] In step b., the industrial truck 8 is driven into the receiving area 3.

[0084] In step c1, the blisters 4 are removed from the industrial truck 8 by means of the conveyor mechanism.

[0085] In step c2, the blisters 4 stacked in the storage section 9 are conveyed through the storage section 9 along the storage direction 17 and held ready for the removal area 10.

[0086] In step d., the uppermost stackable blister 4,5 is transferred by the delivery mechanism from the storage section 9 into the removal area 10 along the feed direction 18.

[0087] This is followed by step e., in which the components are removed from the blister 4 in the removal area 10.

[0088] In step f., the emptied stackable blisters 4,7 are transported through the return section 13 opposite to the storage direction 17.

[0089] Finally, step g. involves returning the emptied stackable blister pack 4,7 to the industrial truck 8.

[0090] A supply device for supplying components to a production line is proposed, which enables efficient operation of the line production.
