Abstract
Description
Technical Field
[0001] This utility model relates to the product channel on the tray of an automatic vending machine. Background Technology
[0002] Existing vending machines have multiple trays arranged vertically inside, each with multiple conveyor lanes, each capable of independent movement. The conveyor lanes are equipped with a transport structure for handling items. To distinguish adjacent items on the lane, dividers protruding from the transport surface are installed. Flat, vertically placed items, in particular, require these dividers for support; otherwise, they are prone to tipping over. The conveyor lanes operate at fixed step intervals, discharging items located between two dividers towards one end of the lane. The dividers eventually move from above to below the conveyor lane.
[0003] The trays are arranged vertically within the vending machine, with a certain distance between adjacent trays to allow space for items and dividers for the upper trays. These dividers remain vertically positioned on the conveyor surface, occupying a significant amount of space outside the vending aisle. This results in a large operational space required for the entire vending machine.
[0004] The internal space of a vending machine is very limited. When the product aisle operation requires a large space, only a small number of items can be placed in the remaining space inside the vending machine. Utility Model Content
[0005] The technical problem this invention aims to solve is how to reduce the space occupied by cargo handling operations.
[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: The cargo channel includes a support component and a cargo-carrying component. The cargo-carrying component is mounted on the support component and includes a chain and chain plates. The chain is mounted on the support component and stretched out. The chain extends above the support component to form a straight section, and extends at one end of the support component to form a curved section. The chain plates are continuously distributed on the chain, and the distribution range of the chain plates covers at least the straight section. The chain plates are provided with a cargo-carrying surface and a partition plate. The partition plate protrudes from the cargo-carrying surface. The partition plate includes a connector and a partition. The connector is connected to the loading surface, and the connector and the partition are movably connected by a slot. The swing direction of the partition on the connector is in the same plane as the extension direction of the straight part. The cargo channel also includes a bending stop bar. The bending stop bar remains stationary relative to the support assembly. The bending stop bar is located at the bend of the chain. The position of the bending stop bar intersects with the range of motion of the partition when it is perpendicular to the loading surface of the chain plate. The partition is prevented from tilting relative to the loading surface of the chain plate by the bending stop bar.
[0007] The connector and the divider are movably connected via a slot. The divider can move relative to the connector, creating a swinging motion. This causes the divider to either bend or flatten. On the chain's carrying surface, the divider will either be in a flat, upright position with the divider perpendicular to the chain, or in a bent, folded position with the divider tilted towards the chain. Because the divider and connector are tightly connected via the slot, this close connection allows the divider to maintain its position relative to the connector, thus maintaining the bend or flattened overall posture and providing a self-locking function.
[0008] The transition between the flat, upright state and the bent, folded state of the partition plate can be achieved simply by swinging the partition relative to the connecting member. The bending stop is used to change the relative position between the partition and the connecting member, but only to obstruct the partition plate from the flat, upright state to the bent, folded state. Thus, the partition plate will always be in the bent, folded state when passing the bending stop, whether in the flat, upright state or not. Compared to existing technologies where the partition plate is always upright on the conveyor surface, this technology frees up space by allowing the partition plate to enter the bent, folded state, ensuring that the space below the vending machine is not excessively occupied by the partition plate in the flat, upright state. This freed-up space can be used to place items in adjacent vending channels below, thus improving the internal space utilization efficiency of the vending machine.
[0009] The process of the partition changing from a flat, upright state to a bent, folded state is a process in which the partition is driven by an external force to swing relative to the connecting parts. The position where this state changes is distributed at the bend of the chain. The reason for setting the position of the state change here is that this is where the item leaves the conveyor. Another reason is that the partition at this position acts as an extension structure at the end of the support component, which can extend the conveying range of the conveyor outward, so that the output item is not affected by the adjacent left and right or upper and lower conveyors, ensuring that the item is output smoothly.
[0010] The optimized slot structure comprises a sliding groove at each end of the connector and a rotating shaft at each end of the separator corresponding to the sliding groove. The separator is movably connected to the connector by being embedded in the sliding groove via the rotating shaft. This slot structure provides a stable connection structure for the separator and a reliable clamping effect at the sliding groove. This clamping effect is used to establish and maintain a tight connection between the rotating shaft of the separator and the connector.
[0011] Although the slot structure establishes a tight connection between the partition and the connector, the partition plate naturally maintains its bent or flattened overall posture through its self-locking function. However, the degree of self-locking in the flattened posture is limited, meaning that the performance in maintaining the partition plate in a flat and upright state needs improvement. Therefore, this invention provides three preferred structures to address this need.
[0012] In the first configuration, the connecting member has a limiting surface located outside the area in the middle of the two sliding grooves. The side of the separator has a restricted surface corresponding to the limiting surface, the width of which is less than or equal to the diameter of the rotating shaft. The separator maintains a perpendicular relative position to the load-bearing surface of the chain plate by connecting the limiting surface and the restricted surface. When the limiting surface and the restricted surface are in contact, the separator is in a flat, upright state, with the restricted surface above the limiting surface. An external force drives the separator, thereby overcoming the friction between the separator and the connecting member, thus changing their relative position. This structure, which enhances self-locking, has the advantages of being easy to design and readily available.
[0013] The second type involves a limiting protrusion on the separator and a corresponding limiting groove on the connector. The separator is embedded in the limiting groove via the limiting protrusion, maintaining a perpendicular position to the load-bearing surface of the chain plate. When the limiting protrusion is embedded in the limiting groove, the separator is in a flat, upright state, with the limiting protrusion positioned above the limiting groove. External force drives the separator, overcoming the friction between it and the connector, thus changing their relative position. Because the connector's clamping action at the slide groove further pushes the separator towards the limiting groove, even if the limiting protrusion is worn or slightly deviates from the limiting groove, it will automatically move towards the limiting groove, where resistance is lower, due to the aforementioned squeezing tendency, thus automatically embedding itself in the limiting groove without requiring specific aiming. This structure, which enhances self-locking, offers advantages such as accurate positioning and strong adaptability.
[0014] The third type involves a blocking surface on the connector. This blocking surface is located downstream of the separator in the swing direction from the straight section to the bend. The separator, through the blocking surface, restricts its range of motion relative to the connector, maintaining a relative position perpendicular to the load-bearing surface of the chain plate. The blocking surface limits the swing range of the separator on the connector, and its location represents the limit position of the separator's swing. At this limit position, the separator is in a flat, upright state. With the blocking surface, the swing range of the separator is distributed on one side of the connector; without the blocking surface, the swing range is distributed on both sides of the connector. Therefore, in addition to providing a limit position for the separator to maintain a flat, upright state perpendicular to the load-bearing surface of the chain plate, the blocking surface also positions the separator tilted towards the load-bearing surface of the chain plate on one side of the connector.
[0015] All three structures significantly improve the performance of the chain plate in maintaining the flat and upright position of the partition plate. The three structures do not interfere with each other. In addition to the three structures being designed individually on the chain plate, any two of them can be combined, or all three can be designed on the chain plate. This overall design, combining multiple retaining structures, is more conducive to maintaining the flat and upright position of the partition plate.
[0016] The bending stop bar remains stationary relative to the supporting assembly. When the moving chain plate passes through the area where the bending stop bar is located, the flattened, upright partition plate is blocked by the bending stop bar, causing the partition plate to change its position relative to the connecting member. The partition plate changes from a flattened overall posture to a bent overall posture. To ensure this change in the partition plate is gradual, the bending stop bar has a preliminary bending guide end and a deep bending guide end. The distance from the preliminary bending guide end to the center of the bend is greater than the distance from the deep bending guide end to the center of the bend. The preliminary bending guide end and the deep bending guide end are arranged separately in the direction around the center of the bend. The deep bending guide end is located downstream of the preliminary bending guide end in the swing direction from the straight section to the bend. The distance from the preliminary bending guide end to the deep bending guide end is less than the length of the partition plate. The partition plate first contacts the preliminary bending guide end, and after being blocked by the preliminary bending guide end, the partition plate is tilted slightly. Then, the partition plate contacts the deep bending guide end, and after being blocked by the deep bending guide end, the partition plate is tilted significantly. Bending the partition in stages can avoid the huge impact force that occurs when bending the partition all at once, and increase the number of contact times to achieve a low-impact bending operation.
[0017] This technical solution also provides a bending stop structure that can easily provide a preliminary bending guide end and a deep bending guide end, that is, the cross-section of the bending stop is L-shaped.
[0018] The separator plate at the bend of the chain acts as an extension of the carrying surface of the chain plate in the straight section, extending the conveying range of the cargo channel. This extension function is based on the fact that during an overturning process, the item is blocked by the separator plate at the bend, forcing it to fall away from the cargo channel. To prevent the item from tipping over, the separator plate needs to be kept flat and upright until the item is easily supported by the separator plate and slides along it. This allows the separator plate to provide more active guidance as the item slides down. To achieve this effect, the direction from the center of the bend to the initial bending guide end is inclined to the straight section. When the separator plate is blocked by the initial bending guide end, the spatial posture change it undergoes provides the aforementioned guiding effect.
[0019] The conveyor surface of the cargo channel is composed of chain plates and a partition plate that creates a separation effect, facilitating the separate placement of items. To improve the flexibility of the cargo channel when receiving items, the chain plates are equipped with a carrying plate, and the partition plate is movably mounted on the carrying plate. The carrying plate has positioning holes, and the connecting member has a positioning protrusion. The connecting member is movably connected to the carrying plate by embedding the positioning protrusion into the positioning hole. The spacing between the partition plates on adjacent chain plates can be adjusted by inserting them into different positioning holes. This allows for flexible adjustment of the conveyor surface during use, significantly improving its efficiency.
[0020] Since the separating effect of the partition plate is manifested along the direction of the chain, the positioning holes are arranged at equal intervals in the direction of the parallel straight part, thus ensuring that the adjustability of the arrangement space on the chain plate is consistent with the conveying direction of the conveying surface of the cargo channel.
[0021] The present invention adopts the above-mentioned technical solution: a foldable partition is set on the cargo channel. The partition can participate in the conveying operation in a flat and upright state, and can also be bent and folded to free up space, effectively reducing the space occupied by the cargo channel operation and improving the internal space utilization efficiency of the vending machine.

[0036] The first embodiment of this utility model, as follows: Figures 1 to 13 As shown.
[0037] The cargo channel includes a support assembly 1, a cargo-carrying assembly, a drive assembly, and a bending stop bar 19.
[0038] Support assembly 1 includes a profile, an active end support, and a passive end support. The profile has a flat structure and a relatively long length. A groove is provided on each of the upper and lower sides of the profile, and the two grooves are symmetrically distributed on the profile. The active end support is installed at one end of the profile, and the passive end support is installed at the other end. Both the active and passive end supports are equipped with rotatable gears, and the movement range of the gear teeth is located in the extension direction of the grooves. The drive assembly includes a motor and a reduction gear structure. The drive assembly has a rotating shaft 16 as the power output end, which connects to the gear on the active end support, thereby providing power from the active end support to the load assembly.
[0039] The load-bearing assembly includes a chain 2 and chain plates 3. The chain 2 is mounted on the support assembly 1 and is connected to a gear. When stretched vertically, the chain 2 forms a structure with arc-shaped ends and a straight middle section. The arc-shaped portion of the chain 2 is formed by following the bend of the gear; this portion is the bend of the chain 2. The straight section of the chain 2 is the straight section. The two straight sections of the chain 2 are distributed vertically, with the upper straight section embedded in the upper groove.
[0040] The chain plate 3 consists of a carrying plate 4 and a partition plate 8.
[0041] The carrying plate 4 is a flat, plate-like structure. One side of the carrying plate 4 has a clamping part 6 for connecting with the links of the chain 2. The clamping part 6 consists of two protruding structures on one side of the carrying plate 4, with the chain links embedded between the two protruding structures. The carrying plate 4 has vertically arranged positioning holes 7 for connecting the carrying plate 4 to the partition plate 8. The partition plate 8 includes a connector 9 and a partition 15, which are movably connected by a slot. Specifically, on the side of the connector 9, each end of the connector 9 has a sliding groove 10, and each end of the partition 15 has a rotating shaft 16 corresponding to the sliding groove 10. The partition 15 is movably connected to the connector 9 by embedding the rotating shaft 16 into the sliding groove 10. After the two are connected in this way, the rotating shaft 16 is clamped within the sliding groove 10. On the other side of the connector 9, the connector 9 is provided with a positioning protrusion 11 corresponding to the positioning hole 7 on the carrier plate 4. The connector 9 is movably connected to the carrier plate 4 by being embedded in the positioning hole 7 through the positioning protrusion 11. When disassembling, it is only necessary to pull the connector 9 out of the carrier plate 4 with force. The partition plate 8 is assembled onto the carrier plate 4 from the other side of the carrier plate 4. The surface of the other side of the carrier plate 4 is the loading surface 5. After assembly, the partition plate 8 protrudes on the side of the carrier plate 4 with the loading surface 5, and the connector 9 is connected to the loading surface 5. After the chain plate 3 and chain 2 are engaged, when the separator 15 is forcefully turned, relative movement occurs between the separator 15 and the connecting member 9. As the direction of the external force changes, the separator 15 swings on the connecting member 9. After the external force disappears, the relative position between the separator 15 and the connecting member 9 is maintained by the shaft 16 being clamped by the connecting member 9 within the groove, exhibiting a self-locking state. In addition, the positioning holes 7 are evenly spaced in the direction of the parallel straight section. Different relative positions between the separator 15 and the connecting member 9 allow the separator plate 8 to obtain a bent overall posture or a flat overall posture. On the loading surface 5 of the chain plate 3, the separator plate 8 can be in a flat and upright state where the separator 15 is perpendicular to the loading surface 5 of the chain plate 3, or in a bent and folded state where the separator 15 is inclined to the loading surface 5 of the chain plate 3.
[0042] To achieve a more stable flat and upright state for the partition plate 8, the following three structural optimizations were made to the partition plate 8 structure in this embodiment. The first structural optimization: The connector 9 has a planar limiting surface 12, located on the side of the connector 9 with the groove, but outside the area directly between the two sliding grooves 10, meaning they are not on the same horizontal plane. The side of the partition plate 15 has a planar restricted surface 17 corresponding to the limiting surface 12, located on the side of the partition plate 15 with the rotating shaft 16, and the width of the restricted surface 17 is less than or equal to the diameter of the rotating shaft 16. After the partition plate 15 rotates on the connector 9, the limiting surface 12 and the restricted surface 17 can fit together, i.e., connect. At this time, the partition plate 8 is perpendicular to the load surface 5, thus allowing the partition plate 15 to maintain a perpendicular relative position to the load surface 5 of the chain plate 3 through the connection of the limiting surface 17 and the limiting surface 12. The second structural optimization is combined with the first structural optimization. The separator 15 has a limiting protrusion 18 that protrudes from the surface of the restricted surface 17. The connector 9 has a limiting groove 13 corresponding to the limiting protrusion 18. The limiting groove 13 is distributed at the location of the limiting surface 12 on the connector 9, and the orientation of the limiting groove 13 is the same as that of the limiting surface 12. When the limiting surface 12 and the restricted surface 17 can fit together, that is, when the separator 8 is perpendicular to the carrying surface 5, the limiting protrusion 18 will be embedded in the limiting groove 13, so that the separator 15 maintains a perpendicular relative position to the carrying surface 5 of the chain plate 3 through the limiting protrusion 18 being embedded in the limiting groove 13. The third structural optimization is also combined with the previous two. The connector 9 has a blocking surface 14. Unlike the limiting groove 13, which is concentrated at the location of the limiting surface 12, the blocking surface 14 is distributed at a position higher than the limiting surface 12. The direction in which the blocking surface 14 acts as a blocking surface intersects with the orientation of the limiting surface 12. The blocking surface 14 is used to limit the swing range of the separator 15 on the connecting member 9. The location of the blocking surface 14 is the limit position of the swing of the separator 15. This limit position is exactly the position where the separator 8 is in a flat and upright state. Therefore, this determines that the positional distribution of the blocking surface 14 relative to the separator 15 is specific. The blocking surface 14 must be located downstream of the separator 15 in the swing direction from the straight part to the turning part. When the separator 15 is in the limit position, the blocking surface 14 limits the movement range of the separator 15 relative to the connecting member 9, maintaining a relative position perpendicular to the loading surface 5 of the chain plate 3. The above three optimized structures are combined without interfering with each other, and overall, they can significantly improve the performance of the chain plate 3 in maintaining the flat and upright state of the separator 8.
[0043] Chain plates 3 are continuously distributed on chain 2, with a length shorter than the chain 2. The distribution range of chain plates 3 just covers a straight section, so that the chain plates 3 located above the support component 1 can be used to place items. The swing direction of the divider 15 on the connector 9 is in the same plane as the extension direction of the straight section. When the divider 8 is in a flat, upright state, it provides a structural basis for efficiently utilizing space to meet the needs of placing items; when the divider 8 is in a bent, folded state, it does not provide a structural basis for placing items. The divider 8 in the flat, upright state is perpendicular to the loading surface 5 of the carrying plate 4.
[0044] In implementation, this technical solution involves installing a bent stop bar 19 on a pallet, which also has multiple cargo channels. The same bent stop bar 19 can serve multiple cargo channels, thus keeping the bent stop bar 19 stationary relative to the support assembly 1.
[0045] The bending stop 19 is located at the bend of the chain 2. The cross-section of the bending stop 19 is L-shaped. The bending stop 19 has a preliminary bending guide end 20 and a deep bending guide end 21. When the partition plate 8 is in a flat and upright state, the partition member 15 is perpendicular to the loading surface 5 of the chain plate 3. In this state, as the chain 2 moves, the partition member 15 will be blocked by the bending stop 19. Therefore, the position of the bending stop 19 intersects with the range of motion of the partition member 15 when it is perpendicular to the loading surface 5 of the chain plate 3. Finally, the partition member 15 is tilted relative to the loading surface 5 of the chain plate 3 by the bending stop 19.
[0046] The distance from the initial bending guide end 20 to the center of the bend is greater than the distance from the deep bending guide end 21 to the center of the bend. The initial bending guide end 20 and the deep bending guide end 21 are arranged separately in the direction around the center of the bend, and the deep bending guide end 21 is located downstream of the initial bending guide end 20 in the swing direction from the straight part to the bend. The distance from the initial bending guide end 20 to the deep bending guide end 21 is less than the length of the separator 15. The direction from the center of the bend to the initial bending guide end 20 is inclined to the straight part. The separator 15 first contacts the initial bending guide end 20 in a flat and upright state. The initial bending guide end 20 blocks the separator 15 from moving with the chain 2. Then, the separator 15 is squeezed by the initial bending guide end 20 and changes its position relative to the connector 9. After being blocked by the initial bending guide end 20, the separator 15 is in a slight tilt. The separator 15 then contacts the deep bending guide end 21. After being blocked by the deep bending guide end 21, the separator 15 is in a large tilt. Finally, the separator 15 leaves the bending stop bar 19 in a bent and folded state.
[0047] Initially, the chain 2, located on the straight section above the profile, is covered with chain plates 3. The partition plates 8 on the chain plates 3 are perpendicular to the loading surface 5 of the carrying plate 4, and are in a flat, upright position. In use, items are placed on the chain plates 3, receiving support from the carrying plate 4 and separation from the partition plates 8. When the conveyor responds to an operation command and outputs items, the chain 2 rotates, driving the chain plates 3 towards the bend where the bending stop bar 19 is located. As the items move from the straight section to the bend with the chain plates 3, they tilt, and the tilted items are guided away from the conveyor by the partition plates 8 located in front of them. Then, the partition plates 8, in a flat, upright position, enter the location of the bending stop bar 19, and finally leave the bending stop bar 19 in a bent, folded state. To restore to the initial state, chain 2 needs to be reversed, allowing all the partition plates 8 that are in a bent and folded state to pass through the bending stop bar 19. At the straight part, the connecting piece 9 is turned to make the partition plates 8 on the chain plate 3 return to a flat and upright state.
[0048] The partition 8 above the cargo channel is in a flat and upright state, while the partition 8 below the cargo channel is in a bent and folded state. The space required for the entire cargo channel operation is significantly smaller than that required for the cargo channel operation when the partitions are always flat and upright.
[0049] The second embodiment of this utility model.
[0050] This embodiment differs from the first embodiment in that it does not have the three preferred structures for improving performance in maintaining the flat and upright state of the partition.
[0051] The third embodiment of this utility model.
[0052] The difference between this embodiment and the first embodiment is that it has a first preferred structure for improving performance in maintaining the flat and upright state of the partition.

[0062] This embodiment differs from the first embodiment in that it has a second and a third preferred structure for improving performance in maintaining the flat and upright state of the partition.
[0063] In the above embodiments, the chain can be covered with chain plates. The chain does not need to rotate in the opposite direction to return to its initial state; it only needs to move in one direction. The partition plate, which is bent and folded down below the profile, enters the straight section above the profile from another bend. At the straight section, the connecting piece is moved to make the partition plate on the chain plate return to its flat and upright state. Other embodiments are thus obtained.
[0064] The above embodiments can also modify the installation structure of the bending stop, combining the bending stop with the support assembly, for example, by fixing the bending stop to the profile, thereby ensuring that the bending stop remains stationary relative to the support assembly. Other embodiments are thus derived.
