[0026] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0034] In supermarkets and other retail establishments, shoppers habitually grab items displayed at the very front of the shelves. If sellers replenish stock by placing the new items in empty spaces at the front, it can lead to products at the back of the shelves being left untouched for extended periods, potentially even expiring. Therefore, sellers should prioritize replenishing stock at the back of the shelves.

[0035] In related technologies, the shelves in display cases are mostly fixed and cannot be moved, making it difficult to replenish stock at the back of the shelves.

[0036] To address the aforementioned technical issues, this application provides a FIFO shelving system and a display case.

[0037] Firstly, such as Figures 1 to 3 As shown, this application provides a FIFO shelf system, including a shelf 1 and guide rails 2. The shelf 1 is used to provide display positions for the displayed items. A first guide 11 and a first follower 12 are arranged sequentially from the front end to the rear end on both sides of the shelf 1. The first guide 11 extends from the front end to the rear end of the shelf 1. The guide rails 2 are arranged in pairs and symmetrically distributed on both sides of the shelf 1. A second guide 21 and a second follower 22 are arranged sequentially from the rear end to the front end of the guide rails 2. The second guide 21 extends from the rear end to the front end of the guide rails 2. The first guide 11 cooperates with the second follower 22, and the second guide 21 cooperates with the first follower 12, so that the second follower 22 moves along the first guide 11 while the first follower 12 moves along the second guide 21.

[0038] When the FIFO shelving system is installed in the display case, guide rails 2 can be installed on the left and right side walls inside the display case to guide the pull-out of the shelving 1. One or multiple FIFO shelving systems can be installed in the display case. When there are multiple FIFO shelving systems, they can be arranged at intervals along the height of the display case.

[0039] In a FIFO shelving system, the end facing the audience (e.g., a customer) is designated as the front end of shelf 1 and guide rail 2, and the end facing away from the audience is designated as the rear end of shelf 1 and guide rail 2. When installed in a display case, the FIFO shelving system can be installed horizontally or at an angle (towards the horizontal). For example, when the FIFO shelving system is installed at an angle, the front end of shelf 1 can be preferentially tilted downwards, allowing the weight of the items displayed on shelf 1 to automatically slide towards the front end of shelf 1.

[0040] In the FIFO shelving system, guide rails 2 are arranged in pairs, for example, there can be two guide rails 2, distributed on both sides of the shelving 1 to provide support for the shelving 1. Of course, this application is not limited to having only two guide rails 2. When the shelving 1 is designed to support heavy objects, there can be four, six, eight, etc., and by increasing the number of guide rails 2 on both sides of the shelving 1, greater support can be provided for the shelving 1.

[0041] In the FIFO shelving system, the first guide 11 can guide the second follower 22, causing the second follower 22 to move along the first guide 11; the second guide 21 can guide the first follower 12, causing the first follower 12 to move along the second guide 21. When the first follower 12 moves, its movement can be either sliding or rolling along the second guide 21; when the second follower 22 moves, its movement can be either sliding or rolling along the first guide 11. The movement patterns of the first follower 12 and the second follower 22 can be the same or different.

[0042] In the FIFO shelving system, when shelving 1 is pulled, the first follower 12 moves along the guide trajectory of the second guide 21; the second follower 22 remains stationary with the guide rail 2, but moves along the guide trajectory of the first guide 11 relative to the first guide 11, thus enabling shelving 1 to be pulled out. Simultaneously, the second follower 22 provides support to the first guide 11 at all times, and the second guide 21 provides support to the first follower 12 at all times, thereby supporting shelving 1 on the guide rail 2. Furthermore, the first follower 12 is located at the rear ends on both sides of shelving 1, and the second follower 22 is located at the front ends of the guide rail 2. When shelving 1 is extended, the first follower 12 cooperates with the second guide 21, and the first guide 11 cooperates with the second follower 22, still supporting shelving 1 on the guide rail 2.

[0043] In the technical solution of this application embodiment, the shelf 1 is movable relative to the guide rail 2. When the FIFO shelf system is installed in the display case, the shelf 1 can be pulled outwards, and the pulled-out shelf 1 can be supported by the guide rail 2 without manual lifting. The replenishment staff can place newly replenished display items (such as goods) near the rear end of the shelf 1, and after replenishing the display items, push the shelf 1 back into the display case. During the sales process, the display items located at the front of the shelf 1 are taken and purchased by consumers first according to their shopping habits, which can naturally achieve first-in-first-out. The shelf 1 of the FIFO shelf system can be pulled out, which facilitates replenishment to the rear end of the shelf 1. After the shelf 1 is pushed back, the display items located at the front of the shelf 1 are displayed first, which can naturally achieve first-in-first-out. Therefore, the FIFO shelf system can not only improve replenishment efficiency and standardize operations, but also effectively reduce the risk of stockpiling near-expiry goods and reduce losses, thereby solving the problem of product date management in commercial scenarios and providing effective support for retail scenarios such as supermarkets and convenience stores that are sensitive to expiration dates.

[0044] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, optionally, the second guide member 21 includes a lower guide portion 211 and an upper guide portion 212 formed on the guide rail 2, and the first follower member 12 is located between the lower guide portion 211 and the upper guide portion 212. From the rear end to the front end of the guide rail 2, the upper guide portion 212 sequentially includes a first guide segment 2121, a second guide segment 2122, and a third guide segment 2123. The first guide segment 2121 and the third guide segment 2123 are both arranged parallel to the lower guide portion 211. The distance between the first guide segment 2121 and the lower guide portion 211 is less than the distance between the third guide segment 2123 and the lower guide portion 211. The two ends of the second guide segment 2122 are respectively connected to the first guide segment 2121 and the second guide segment 2122.

[0045] The second guide member 21 is formed on the guide rail 2, that is, the second guide member 21 and the guide rail 2 are an integral structure. For example, when the guide rail 2 is made of metal, the second guide member 21 and the guide rail 2 can be formed by stamping and bending the entire metal plate, or by milling the entire metal material; when the guide rail 2 is made of non-metallic material, the second guide member 21 and the guide rail 2 can be formed simultaneously by thermoforming through a mold.

[0046] When the first follower 12 is located near the rear end of the guide rail 2, the lower guide 211 can provide support for the first follower 12, and the first guide segment 2121 can cooperate with the lower guide 211 to constrain the vertical displacement of the first follower 12; the second follower 22 can provide support for the shelf 1 near the front end of the shelf 1. As the shelf 1 is pulled out, the supporting force on the shelf 1 gradually converges towards the rear end of the shelf 1, the supporting force of the lower guide 211 on the shelf 1 decreases, and the supporting force of the upper guide 212 on the shelf 1 increases (in fact, the upper guide 212 gradually provides an increased downward pressure to the shelf 1). The first guide segment 2121, the second guide segment 2122, and the third guide segment 2123 can all constrain the first follower 12, thereby preventing the shelf 1 from overturning and achieving effective support for the shelf 1.

[0047] The first guide section 2121, in conjunction with the lower guide section 211, can guide the movement trajectory of the first follower 12. As the shelf 1 is pulled out, the first guide section 2121 gradually increases the downward pressure on the first follower 12. When the first follower 12 moves to the second guide section 2122, the front end of the shelf 1 lacks effective support and tends to tilt downwards due to its own weight. At this time, the second guide section 2122 provides downward pressure to the shelf 1 through the first follower 12, and the first follower 12 adheres to the second guide section 2122. When the first follower 12 moves to the third guide section 2123, the first follower 12 adheres to the third guide section 2123, and the third guide section 2123 provides downward pressure to the shelf 1.

[0048] In the technical solution of this application embodiment, as the shelf 1 is pulled out, the first follower 12 can sequentially conform to the first guide section 2121, the second guide section 2122, and the third guide section 2123, with the second guide section 2122 serving as a transition. Furthermore, the distance between the third guide section 2123 and the lower guide section 211 is greater than the distance between the first guide section 2121 and the lower guide section 211, allowing the front end of the shelf 1 to tilt downwards when pulled out. At this time, the displayed items are concentrated at the front end of the shelf 1 due to their own weight, further facilitating the replenishment of the displayed items.

[0049] like Figures 2 to 4 As shown, according to some embodiments of this application, optionally, from the front end to the rear end of the shelf 1, the first guide 11 sequentially includes a stop portion 111, a guide portion 112, and a mating portion 113. Both the stop portion 111 and the mating portion 113 are located below the guide portion 112. The stop portion 111 abuts against the second follower 22 to limit the retraction stroke of the shelf 1. The mating portion 113 abuts against the guide rail 2 or the second follower 22 to limit the outward pulling stroke of the shelf 1. The guide portion 112 abuts against the top of the second follower 22 to guide the second follower 22 to move along the guide portion 112.

[0050] For example, the first guide 11 may be formed by bending a sheet metal and welded to the shelf 1. When the shelf 1 is made of metal, the first guide 11 may also be a part of the shelf 1 formed on the side wall of the shelf 1.

[0051] In the FIFO shelving system, the guide portion 112 always abuts against the top of the second follower 22, which provides support for the shelving 1 via the guide portion 112. Furthermore, the second follower 22 always moves within the area defined by the stop portion 111, the guide portion 112, and the mating portion 113. When the shelving 1 is pushed back, the stop portion 111 abuts against the second follower 22, preventing the shelving 1 from being pushed back further, thus limiting the retraction stroke of the shelving 1. When the shelving 1 is pulled out, the second follower 22 can abut against the mating portion 113 to limit the outward pulling stroke of the shelving 1, or a corresponding structure (such as the limiting member 26 mentioned below) can be provided on the guide rail 2 to abut against the mating portion 113 to limit the outward pulling stroke of the shelving 1.

[0052] In the technical solution of this application embodiment, the guide part 112 abuts against the top of the second follower 22, and the second follower frame can always provide an upward support force for the shelf 1; the stop part 111 can limit the retraction stroke of the shelf 1, and the mating part 113 can limit the outward pulling stroke of the shelf 1, thereby limiting the stroke range of the shelf 1 and preventing the shelf 1 from falling off the support of the guide rail 2.

[0053] like Figure 3 , Figure 4 and Figure 6 As shown, according to some embodiments of this application, optionally, a locking wrench 23, a locking hole 24, and an unlocking port 25 are provided on the guide rail 2. The locking wrench 23 includes a mounting part 231, a locking part 232, and an operating part 233. The mounting part 231 is rotatably connected to the guide rail 2 and is provided with a snap-fit ​​protrusion 2311, which is used to snap into the locking hole 24 and the unlocking port 25 respectively. The locking part 232 is connected to the mounting part 231 and is used to abut against the stop part 111 to lock the shelf 1. The operating part 233 is connected to the mounting part 231 and is used to provide an operating position.

[0054] For example, the mounting part 231 can be mounted on the guide rail 2 by means of a press-fit nut post, and can rotate along the axis of the press-fit nut post. The snap-fit ​​protrusion 2311 can be a spring plunger movably connected to the mounting part 231 (the mounting part 231 is provided with a hole, and the spring plunger is installed in the hole).

[0055] When displaying items (selling goods), the latching protrusion 2311 engages with the locking hole 24, and the locking part 232 abuts against the stop part 111, locking the shelf 1 and preventing it from sliding outward. When restocking is needed, the operating part 233 is activated, causing the latching protrusion 2311 to disengage from the locking hole 24 and engage with the unlocking port 25. At this time, the locking part 232 disengages from the stop part 111, allowing the shelf 1 to be pulled out.

[0056] In the technical solution of this application embodiment, the guide rail 2 is equipped with a locking wrench 23 to cooperate with the shelf 1 (stop part 111), which can lock and unlock the shelf 1, thereby avoiding malfunction of the shelf 1 and improving reliability.

[0057] like Figure 3 As shown, according to some embodiments of this application, optionally, a limiting member 26 is provided on the guide rail 2. The limiting member 26 is located between the second guide member 21 and the second follower member 22. The limiting member 26 includes a longitudinal portion 261 connected to the guide rail 2 and a transverse portion 262 connected to the longitudinal portion 261. The limiting member 26 is used to abut against the mating portion 113.

[0058] For example, the guide rail 2 can be made of metal by stamping. At the location of the limiting member 26, the metal material of the guide rail 2 is stamped and bent, forming a hole in the original position, and the bent material forms the limiting member 26. The material stamped out of the guide rail 2 is further bent to form a horizontal part 262 and a vertical part 261. The horizontal part 262 is located above the vertical part 261 and connected to the vertical part 261.

[0059] In the technical solution of this application embodiment, a limiting member 26 is provided on the guide rail 2. When the shelf 1 is pulled out to the point where the limiting member 26 abuts against the mating part 113, the limiting member 26 can limit the shelf 1, thereby preventing the shelf 1 from being pulled out. Furthermore, the limiting member 26 includes a connected longitudinal part 261 and a transverse part 262, which can improve its own structural strength.

[0060] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, optionally, the first guide 11 is located between the lower guide portion 211 and the upper guide portion 212; the first follower 12 is the first roller 121 and the second follower 22 is the second roller 221, and the outer diameter of the first roller 121 is larger than the outer diameter of the second roller 221.

[0061] For example, the first roller 121 is rotatably mounted on the side wall of the shelf 1; the second roller 221 is rotatably mounted on the guide rail 2.

[0062] In the technical solution of this application embodiment, the first roller 121 can roll in contact with the second guide 21, and the second roller 221 can roll in contact with the first guide 11, thereby reducing the resistance when the shelf 1 is pulled out and improving the smoothness of the shelf 1 being pulled out. The second roller 221 has a small outer diameter and the first roller 121 has a large outer diameter. The first guide 11 is located between the lower guide portion 211 and the upper guide portion 212, which can reduce the space occupation while ensuring that each part performs its function.

[0063] like Figure 2 , Figure 9 and Figure 10 As shown, according to some embodiments of this application, optionally, the FIFO shelf system further includes a separator 3, there are multiple separators 3, the multiple separators 3 divide multiple channels on the shelf 1, the multiple channels are distributed side by side from the left end to the right end of the shelf 1.

[0064] In the multiple cargo channels separated by the separator 3, the width of each cargo channel can be the same, or a portion of the cargo channels can have the same width and a portion of the cargo channels can have different widths, or all the cargo channels can have different widths.

[0065] The divider 3 is detachably connected to the shelf 1. The divider 3 includes a divider plate 31 and a plurality of claws 32 extending outward from the ends of the divider plate 31. The claws 32 are located at the bottom end and / or rear end of the divider plate 31. The shelf 1 is provided with a slot 13, and the claws 32 are engaged with the slot 13.

[0066] For example, the partition 31 can be designed with a cutout to reduce weight.

[0067] The claw 32 may be located only at the bottom end of the partition plate 31, or only at the rear end of the partition plate 31, or both the bottom end and the rear end of the partition plate 31 may be connected to the claw 32. When the bottom end and / or the rear end of the partition plate 31 are connected to the claw 32, the number of claws 32 connected to each is not limited to one.

[0068] Preferably, the bottom and rear ends of the partition plate 31 are connected to claws 32, and correspondingly, the bottom and rear walls of the shelf 1 are provided with slots 13.

[0069] In the technical solution of this application embodiment, the separator 3 is connected to the slot 13 of the shelf 1 by the claw 32. The number of separators 3 can be set according to the requirements, and the number and width of the cargo channels can be flexibly adjusted.

[0070] Furthermore, the number of slots 13 is an integer multiple of the number of claws 32. The slots 13 provide engagement positions for the claws 32. By engaging with different slots 13, the claws 32 can adjust the installation position of the partition plate 31 on the shelf 1, thereby adjusting the width of the cargo aisle.

[0071] like Figure 10 As shown, according to some embodiments of this application, optionally, the free end of the claw 32 is provided with an extension 321, and the extension direction of the extension 321 is set at an angle to the direction in which the claw 32 extends outward from the partition plate 31.

[0072] The angle between the extension direction of the extension 321 and the direction in which the claw 32 extends outward from the partition plate 31 can be acute, right, or obtuse.

[0073] Preferably, the extension direction of the extension 321 is parallel to the edge of the corresponding partition plate 31, and the extension direction of the extension 321 is perpendicular to the direction in which the claw 32 extends outward from the partition plate 31.

[0074] In the technical solution of this application embodiment, the free end of the claw 32 is provided with an extension 321, and the length of the slot 13 is greater than the length of the claw 32. After the claw 32 is inserted into the slot 13, the separator 3 can be pushed along the extension direction of the extension 321 so that the corresponding wall of the shelf 1 is engaged in the gap between the separator 31 and the extension 321, thereby improving the connection strength between the separator 3 and the shelf 1.

[0075] Furthermore, in the claw 32 at the rear end of the partition plate 31, the extension 321 extends downward; in the claw 32 at the bottom end of the partition plate 31, the extension 321 extends toward the front end of the shelf 1, which can improve the reliability of the partition 3 during use and facilitate the insertion and removal of the partition 3.

[0076] Furthermore, the distance between the extension 321 and the bottom end of the partition plate 31 is smaller than the distance between the extension 321 and the rear end of the partition plate 31; at least one claw 32 located at the rear end of the partition plate 31 is provided with a positioning element 322, which abuts against the rear end of the shelf 1. When installing the partition 3, the claw 32 is first inserted into the slot 13, then the partition 3 is pulled toward the front end of the shelf 1, and finally the positioning element 322 is installed on the claw 32, which can prevent the partition 3 from falling off; when disassembling the partition 3, the positioning element 322 is first removed, then the partition 3 is pushed toward the rear end of the shelf 1, and finally the claw 32 is pulled out from the slot 13.

[0077] like Figure 5 , Figure 7 and Figure 8 As shown, according to some embodiments of this application, optionally, the FIFO shelf system further includes an adjustment component 4, which includes a mounting component 41, a swing component 42, and an adjustment component 43; the mounting component 41 is detachably connected to the left end and / or the right end of the shelf 1, one end of the swing component 42 is rotatably connected to the mounting component 41, and the other end is rotatably connected to the adjustment component 43, and the adjustment component 43 is used to adjust the width of the aisle on the shelf 1.

[0078] Adjustment component 4 is installed on the side wall of shelf 1. For example, it can be located at the left end of shelf 1, or at the right end of shelf 1, or both the left and right ends of shelf 1 can be equipped with adjustment component 4.

[0079] In the adjustment assembly 4, the swing member 42 and the mounting member 41, as well as the swing member 42 and the adjusting member 43, are rotatably connected. This can be understood as the swing member 42 and the mounting member 41 being able to rotate relative to each other at the connection point, and the swing member 42 and the adjusting member 43 being able to rotate relative to each other at the connection point, under certain applied forces and / or under certain conditions. When the applied force is too small to push the swing member 42 and / or the adjusting member 43, they cannot rotate, or when the conditions are not met, the swing member 42 and the mounting member 41, as well as the swing member 42 and the adjusting member 43, cannot rotate relative to each other.

[0080] In the technical solution of this application embodiment, the adjustment component 4 includes a mounting component 41, a swing component 42, and an adjustment component 43. By adjusting the relative posture of the three components, the position of the adjustment component 43 can be adjusted, thereby adjusting the width of the cargo channel and flexibly setting the width of the cargo channel.

[0081] like Figure 8 As shown, according to some embodiments of this application, optionally, the mounting member 41 is provided with snap-fit ​​feet 411, which snap-fit ​​feet 411 are connected to the shelf 1. There can be two snap-fit ​​feet 411. When installed on the shelf 1, one snap-fit ​​foot 411 can fit against the inner surface of the side wall of the shelf 1, and the other snap-fit ​​foot 411 can fit against the outer surface of the side wall of the shelf 1, thereby snap-fitting with the shelf 1.

[0082] To further improve the stability of the mounting component 41, the snap-fit ​​feet 411 and the side wall of the shelf 1 can be tightened with bolts and nuts.

[0083] like Figure 7 and Figure 8 As shown, according to some embodiments of this application, optionally, the mounting member 41 and the swing member 42, and the swing member 42 and the adjusting member 43 are connected by bolts 44 and nuts 45; the adjusting member 43 is provided with a relief opening 431, which is used to avoid the head of the bolt 44.

[0084] When it is necessary to adjust the width of the cargo channel (that is, to adjust the position of the adjusting component 43), loosen the bolt 44 and nut 45, and tighten the bolt 44 and nut 45 after adjustment. When the adjusting component 43 is in contact with the mounting component 41, the clearance opening 431 can avoid the bolt 44 connecting the mounting component 41 and the swing component 42, and does not interfere with the head of the bolt 44.

[0085] Preferably, the swing member 42 is provided with a stop 421, which enables the swing member 42 to adjust its posture within a 90° range.

[0086] Furthermore, there are multiple mounting parts 41 and multiple swing parts 42, and they correspond one to one. The multiple swing parts 42 are arranged in parallel, so that the adjusting part 43 is always parallel to the separator 3 when adjusting its position.

[0087] like Figure 11 and Figure 12 As shown, according to some embodiments of this application, optionally, the FIFO shelf system further includes a propulsion assembly 5, which includes a base 51, a front end baffle 52, and a rear end baffle 53; the base 51 is disposed on the shelf 1, and an elastic element 511 and a deceleration belt 512 are disposed on the base 51; the front end baffle 52 is mounted on the base 51 and is used to block the displayed items at the front end of the shelf 1; the rear end baffle 53 is connected to the elastic element 511 and slides in cooperation with the deceleration belt 512 to push the displayed items toward the front end of the shelf 1.

[0088] On shelf 1, the propulsion component 5 can be installed in one cargo channel or in multiple cargo channels.

[0089] For example, the elastic element 511 can be a rubber strip, one end of which is fixedly mounted on the base 51, and the other end is connected to the rear end baffle 53.

[0090] In the technical solution of this application embodiment, the rear end baffle 53 of the push assembly 5 can push the display items toward the front end of the shelf 1 under the pull of the elastic member 511. A deceleration toothed belt 512 is provided on the base 51, and the rear end baffle 53 (and the pushed display items) slide on the deceleration toothed belt 512, which can slow down the movement speed and make the pushing of the display items smoother.

[0091] Secondly, such as Figure 13 As shown, this application provides a display cabinet, including a cabinet body 6, a cabinet door 7, and a FIFO shelf system. The cabinet door 7 is hinged to the cabinet body 6, and multiple FIFO shelf systems are installed at intervals in the height direction of the cabinet body 6 inside the cabinet body 6.

[0092] For example, the display cabinet can be configured as a single door, with one side of the cabinet door 7 hinged to the cabinet body 6 and the other side connected to the cabinet body 6 via a lock.

[0093] In the technical solution of this application embodiment, the display cabinet includes a FIFO shelf system, and therefore has all the advantages of the FIFO shelf system in the above embodiments, which will not be repeated here.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
