[0002] The invention relates to a storage lift for storing stored goods, which has an operating opening for storing and retrieving the stored goods, at least one storage goods carrier for receiving the stored goods and for pulling them out of the operating opening along a pull-out path and at least one guide device for guiding the storage goods carrier along the pull-out path.

[0003] A storage lift of the type mentioned above has a plurality of storage locations where load carriers are accommodated for storing stored goods. For storage and retrieval of stored goods, a load carrier in which the stored goods are stored or in which the stored goods to be retrieved are located is removed from the storage location by a transport device and transported to the access opening. An operator can then use the access opening to remove stored goods from the load carrier for retrieval or position stored goods on the load carrier for storage.

[0004] To facilitate access to the stored goods in the access opening, it is known from DE 10 2019 204 998 A1 to transport the storage goods carriers in a tilted position into the access opening. However, this solution has the disadvantage that, with deep storage goods carriers, the rear stored goods are difficult to reach.

[0005] The present invention is based on the object of creating a storage lift which enables improved accessibility of stored goods on a storage goods carrier for storage and retrieval.

[0006] To solve the problem, a storage lift with the features of claim 1 is proposed.

[0007] Advantageous embodiments of the storage lift are the subject of the dependent claims. According to one aspect of the invention, a storage lift for storing stored goods is proposed. The storage lift has an access opening for loading and unloading the stored goods, at least one storage goods carrier for receiving the stored goods and for pulling them out of the access opening along a pull-out path, and at least one guide device for guiding the stored goods carrier along the pull-out path. The guide device is designed such that the stored goods carrier pivots when pulled out of the access opening.

[0008] The storage lift according to the invention is characterized in that the storage goods carrier pivots when pulled out and assumes an inclined position.

[0009] This allows for improved accessibility and easier removal of stored goods on a storage carrier. In particular, with a deep storage carrier, the rear storage goods are more easily accessible.

[0010] The storage lift can be an automatic storage rack, which is particularly designed as a vertical lift or carousel rack.

[0011] The storage lift advantageously comprises a housing in which a plurality of stacked storage locations for storage goods carriers are provided. Furthermore, the storage lift advantageously comprises a plurality of storage goods carriers. Furthermore, the storage lift can comprise an automatic transport device by means of which the storage goods carriers can be transported from a storage location to the access opening and vice versa.

[0012] Advantageously, the storage goods carrier is transferred into an inclined position during pivoting, in particular into a position inclined to a vertical axis or vertical axis of the storage lift and / or a horizontal axis of the storage lift.

[0013] Advantageously, when the load carrier is pulled out from a retracted position, in which it is aligned parallel to the horizontal axis of the storage lift and orthogonal to the vertical axis of the storage lift, it is transferred into an inclined position, a pivoted position, or an oblique position, in which the load carrier forms an angle to the vertical and horizontal axes of the storage lift. When the load carrier is pushed into the access opening, it is transferred from the inclined position to the retracted position.

[0014] In an advantageous embodiment, a section of the storage carrier pivots out of the access opening when pulled out. This improves handling during loading and unloading, as the rear storage items on the storage carrier are more easily accessible.

[0015] In an advantageous embodiment, the storage lift is designed as a carousel with a revolving transport device comprising a plurality of support sets, on which at least one load carrier is mounted. This allows the load carriers to rotate according to the paternoster principle. Each support set can have a frame within which one or more load carriers can be arranged. The frame can have a floor on which the load carriers rest, a rear wall, two side walls, and a partition wall.

[0016] Advantageously, the guide rails are arranged on the side walls and / or a partition wall of the support set. For this purpose, for example, a screw connection and / or welded connection can be used.

[0017] The support unit serves to hold the support set on the revolving transport device. The transport device transports the load carrier to the access opening for storage and retrieval. The transport device can have a drive means in the form of a revolving chain, with the support unit being connected to the chain. The guide device is advantageously arranged on the support set.

[0018] In an advantageous embodiment, the guide device has guide rails that are arranged on a side wall and / or a partition wall of the support set. The guide rails can be connected to the side wall and / or the partition wall via a screw connection and / or a welded connection.

Advantageously, the guide rails are made of a metal or a plastic, in particular a fiber-reinforced plastic.Another advantage is that the guide rails have an approximately C-shaped cross-section.

[0019] In an advantageous embodiment, the guide rails have a straight section, an inclined section, and a curved section arranged between the straight section and the inclined section. The straight section enables the load carrier to initially run approximately parallel to a support base. Advantageously, the straight section runs parallel to a horizontal axis of the storage lift. Advantageously, the straight section and / or the curved section have a length designed such that the load carrier only transitions into an inclined position when a front edge of the load carrier has passed a predefined point outside the access opening. The curved section enables a smooth transition between the straight section and the inclined section.The inclined section allows the storage carrier to pivot or transition into an inclined position when pulled out. The inclined section has a gradient, whereby the degree of inclination of the storage carrier can be adjusted depending on the gradient. Advantageously, the guide elements, designed as rollers, are located in a retracted position in the straight section and in an inclined position in the inclined section.

[0020] In an advantageous embodiment, the guide rails have a curved profile with a substantially straight section and a curved section. The substantially straight section enables the load carrier to initially run approximately parallel to a support base. Advantageously, the straight section runs parallel to a horizontal axis of the storage lift. Advantageously, the straight section has a length designed such that the load carrier only transitions into an inclined position when a front edge of the load carrier has passed a predefined point outside the access opening. The curved profile, in particular the curved section, enables the load carrier to pivot or transition into an inclined position when it is pulled out.The curved profile, in particular the curved section, has a radius, which can be used to adjust the inclination of the load carrier. Advantageously, the guide elements, designed as rollers, are located in a retracted position in the straight section.

[0021] In an advantageous embodiment, the load carrier has guide elements that are guided in the guide rails. The guide elements enable the load carrier to be easily pulled out of the access opening. Advantageously, the guide elements are designed as rollers that are rotatably mounted on the load carrier and are accommodated by the guide rails.

[0022] In an advantageous embodiment, the guide device has a support roller on which the load carrier rests and rolls when pulled out. The load carrier is supported on the support roller when the load carrier is in the inserted position. When the load carrier is pulled out, the load carrier, in particular a base of the load carrier, initially rolls on the support roller. When the load carrier has reached a certain incline, the load carrier, in particular the base of the load carrier, moves away from the support roller.

[0024] In an advantageous embodiment, a surface of the unwinding roller has an adhesive layer. The adhesive layer can be formed as a rubberized layer and / or as a contoured surface, for example in the form of elevations and / or depressions.

[0025] In an advantageous embodiment, the unwinding roller has a guide element at each end, wherein the at least one storage goods carrier is guided between the two guide elements when pivoting into the operating opening and / or when pulling out of the operating opening. As a result, the storage goods carrier is securely guided when pulling out of the operating opening and / or when pushing into the operating opening. The guide elements can be designed as discs, wherein a disc is arranged at each end on the unwinding roller. If the unwinding device has a plurality of unwinding rollers, then each unwinding roller advantageously has a guide element at each end, for example a guide element designed as a disc. Each guide element, in particular each disc, advantageously has a bevelled guide surface on the edge.The inner sides of the discs facing the unwinding roller can be provided with an adhesive layer, for example a rubber layer.

[0026] In an advantageous embodiment, the rolling device is arranged on a door closing the operating opening, in particular a sliding door with a safety rocker, and / or on a housing of the storage lift. Furthermore, the rolling device is advantageously arranged on the door closing the operating opening, in particular the sliding door with a safety rocker. Due to the closing door, in particular a sliding door, which is arranged below the operating opening, the guide rails initially run approximately parallel to a supporting floor or the guide rails have a straight section. When pulled out, the storage goods carrier, in particular the base of the storage goods carrier, rolls on the support roller until a front edge of the storage goods carrier, in particular a front edge of the base of the storage goods carrier, rests on the rolling device.As soon as a front edge of the load carrier passes the unwinding device, the load carrier pivots or is moved into the inclined position. Once the front edge of the load carrier has passed the unwinding device, the load carrier, in particular the base of the load carrier, is removed from the support roller, so that the load carrier, in particular the base of the load carrier, only rolls on the unwinding device. The unwinding device has a roll-off roller that is rotatably mounted on the door, in particular on the sliding door with a safety rocker.

[0027] Advantageously, the unwinding device is rotatably mounted on a support structure that is attached to the closing door and / or the housing.

[0040] Fig. 11 is an enlarged perspective view of a rolling device according to a second embodiment; and Fig. 12 is an enlarged perspective view of the section A marked in Fig. 11.

[0041] Fig. 1 shows a storage lift 10 for storing goods. The storage lift 10 is a revolving system and comprises a housing 11, goods carriers 12 for receiving the goods, an automatic transport device 13 arranged within the housing 11 for transporting the goods carriers 12, which circulate along a vertical axis VA of the storage lift 10 according to the paternoster principle, and an access opening 14 through which the goods can be loaded and unloaded. The access opening 14 can be closed with a door 44, which in this case is a sliding door 45.

[0042] As shown in Fig. 2, the storage goods carriers 12 are accommodated in support sets 17, which are attached to a circulating chain 15 via support units 16.

[0043] The support set 17 has a frame 18 in which, for example, two storage goods carriers 12 are arranged. The frame 18 is formed from a support set base 20 on which the storage goods carriers 12 rest, a support set rear wall 22, two support set side walls 24, and a support set partition wall 26.

[0044] The storage goods carriers 12 can be pulled out of the service opening along a pull-out path WA. For this purpose, the storage goods carriers 12 are designed as drawers 48, as shown in Fig. 2. Each drawer 48 has a base 50, side walls 52 surrounding the base 50, and a partition wall 54. To pull the drawer 48 out of the service opening 14, the side wall 52 facing the service opening 14 has a handle 56.

[0045] For the storage and retrieval of stored goods, the support set 17 with the storage goods carriers 12 is conveyed into the access opening 14 of the storage lift 10 by means of the transport device 13. An operator can then remove stored goods from the storage goods carrier 12 for retrieval or position stored goods on the storage goods carrier 12 for storage via the access opening 14.

[0046] In order to enable improved accessibility and easier removal of stored goods located on the storage goods carriers 12, the storage goods carriers 12 are pivotable, in particular pivotable out of the service opening, as can be seen in Fig. 1.

[0047] As shown in Figs. 3 and 4, the support set 17 has a guide device 28 for guiding the load carrier 12 along the extension path WA. The guide device 28 is designed such that the load carrier 12 pivots when pulled out of the access opening 14.

[0048] The guide device 28 has two guide rails 30, one guide rail 30 being fastened, for example, screwed and / or welded, to an inner side of a support set side wall 24 and the other guide rail 30 being fastened, for example, screwed and / or welded, to an inner side of the support set partition wall 26. The guide rails 30 are made of a metal or a plastic, in particular a fiber-reinforced plastic. The guide rails 30 are approximately C-shaped in cross-section, as shown in Figures 6 and 7.

[0049] As shown in Figures 3 to 5, guide elements 31 of the storage goods carrier 12 are accommodated within the guide rails 30. The guide elements 31 are designed as rollers 32 that are rotatably mounted on the storage goods carrier 12, wherein the rollers 32 are guided by the guide rails 30 when the storage goods carrier 12 is pulled out.

[0050] The guide rails 30 have a straight section 34 extending in a horizontal direction HR of the storage lift 10, a curved section 36 adjoining thereto and an inclined section 38 adjoining the curved section 36.

[0051] In addition, the guide device 28 has a support roller 40, on which the base 50 rests and rolls when pulled out of the service opening 14, as well as a rolling device 42 that is arranged on the sliding door 44. The rolling device 42 has a rolling roller 43 that is rotatably mounted on the sliding door 44, in particular on a box-shaped support structure 60 made of sheet metal that is attached to the sliding door 44. The pulling out and pivoting of the storage goods carrier 12 from the service opening 14 is described below with reference to Figures 3 to 5. In Fig. 3, the storage goods carrier 12 is shown in the inserted position. As shown, the rollers 32 are located within the straight section 34 of the guide rails 30 and a front edge 46 of the storage goods carrier 12, in particular of the base 50, rests on the support roller 40.By pulling the handle 56, the storage carrier 12, designed as a drawer, is pulled out of the access opening 14. The rollers 32 are guided along the straight section 34, so that the storage carrier 12 initially runs approximately parallel to the support base 20. The storage carrier 12, in particular the base 50, rolls on the support roller 40 until the front edge 46 rests on the unwinding roller 43 of the unwinding device 42 and the roller 32 is located within the curved section 36, as shown in Fig. 4.

[0052] As the rollers 32 transition from the curved section 36 to the inclined section 38, the load carrier 12 begins to pivot. As a result, the load carrier 12, in particular the base 50, moves away from the support roller 40 and only rolls on the unwinding roller 43, as shown in Fig. 5. The load carrier 12 is now pulled out of the access opening 14 until it is pivoted out of the access opening 14, as shown in Figs. 1 and 5.

[0053] A second embodiment of the guide rails 30 is described below, wherein the same reference numerals are used for identical or functionally identical parts.

[0054] The guide rails 30 according to the second embodiment differ from the first embodiment in that they have a curved profile 58 with a substantially straight section 34 and a curved section 36, as can be seen in Figures 8 to 10. The guide rails 30 of the second embodiment also have an approximately C-shaped cross-section, as shown in Figure 10.

[0055] When the load carrier 12 is pulled out of the service opening 14, the rollers 32 are guided along the essentially straight section 34 so that the load carrier 12 initially runs approximately parallel to the support base 20. The load carrier 12, in particular the base 50, rolls on the support roller 40 until the front edge 46 rests on the unwinding roller 43 of the unwinding device 42. When the rollers 32 transition into the curved section 36, the load carrier 12, in particular the base 50, begins to move away from the support roller 40 and to pivot. In the inclined position, the load carrier, in particular the base 50, then only rolls on the unwinding roller 43. The load carrier 12 is now pulled out of the service opening 14 until it is pivoted out of the service opening 14.

[0056] A further embodiment of the unwinding device is explained below, wherein the same reference numerals are used for identical or functionally identical parts.

[0057] Figures 11 and 12 show a second embodiment of the unwinding device

[0058] 42, which differs from the first embodiment in that the unwinding device 42 has three unwinding rollers 43, wherein on each unwinding roller 43 a storage goods carrier 12 is pivoted out of the operating opening and into the operating opening 14.

[0059] As shown in Fig. 11, the three unwinding rollers 43 are rotatably mounted on the box-shaped support structure 60, which is attached to the sliding door 44. Each of the unwinding rollers 43 has a surface 62 with an adhesive layer 64 and two guide elements 66 arranged at its ends.

[0060] The adhesive layer 64 is presently a rubber layer 68. The rubber layer 68 promotes contact between the unwinding rollers 43 and the load carrier 12 and thus also the braking effect. In an alternative embodiment not shown, the adhesive layer 64 can be formed as a contoured surface, for example in the form of elevations and / or depressions.

[0061] In order to prevent the storage goods carriers 12 from swinging out of the operating opening 14 too quickly and filling goods from falling out, each unwinding roller

[0062] 43 has a braking device 69 in the form of a rotation brake 71. The guide elements 66 are designed as discs 70, each disc 70 being firmly connected at its end to the unwinding roller 43. Each guide element 66 or each disc 70 has a beveled guide surface 72 on its edge, as can be seen in Fig. 12. In addition, the inner sides 74 of the discs 70 facing the unwinding roller 43 can be provided with an adhesive layer, for example a rubber layer.

[0063] The guide elements 66, in particular the beveled guide surfaces 72, prevent the storage carrier 12 from tilting when being inserted into the access opening and / or pulled out of the access opening 14. The storage lift 10 according to the invention is characterized by the guide device 30, which is designed to pivot the storage carrier 12 and pivot it out of the access opening 14. This improves the removal of stored goods and provides better accessibility to the rear part of the storage carrier 12 in the case of deep storage carriers.
