Description

Technical Field

[0001] The present invention relates to a goods channel on a tray of a vending machine. Background Art

[0002] Inside the existing vending machine, multiple trays are provided in the vertical direction. Each tray is provided with multiple goods channels, and each goods channel can move independently. A conveying structure for carrying items is provided on the goods channel. In order to distinguish the adjacent items front and back on the goods channel, a partition structure protruding from the conveying surface is provided on the goods channel. Especially for flat vertically placed items, a partition is needed to provide support, otherwise they are very easy to fall. When the goods channel outputs items, it will operate at a fixed step, so that the items located between two partitions are output outward towards one end of the goods channel. The partition on the goods channel will finally move from above the goods channel to below the goods channel.

[0003] The trays are distributed up and down in the vending machine. A certain distance needs to be reserved between the adjacent upper and lower trays to make room for placing items and the partitions of the upper trays. The partitions always stand upright on the conveying surface. Looking at the entire goods channel, the partitions occupy a large space outside the goods channel. This makes the space required for the entire goods channel operation relatively large.

[0004] The internal space of the vending machine is very limited. When the goods channel operation requires a large amount of space, then only a small number of items can be placed in the remaining space inside the vending machine. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to reduce the space occupied by the goods channel operation.

[0006] To solve the above technical problem, the present invention adopts the following technical solution: The goods channel includes a support assembly and a load-carrying assembly. The load-carrying assembly is installed on the support assembly. The load-carrying assembly includes a chain and a chain plate. The chain is installed on the support assembly and stretched out. The chain forms a straight part above the support assembly and a bent part at one end of the support assembly. The chain plates are continuously distributed on the chain, and the distribution range of the chain plates covers at least one straight part. A load-carrying surface and a partition are provided on the chain plate. The partition protrudes from the load-carrying surface. The partition includes a connecting piece and a separating piece. The connecting piece is connected to the load-carrying surface. The connecting piece and the separating piece are movably connected in a card slot manner. The swinging direction of the separating piece on the connecting piece is in the same plane as the extending direction of the straight part. The goods channel further includes a bent stop rod. The bent stop rod remains stationary relative to the support assembly. The bent stop rod is located at the bent part of the chain. The position where the bent stop rod is located intersects with the movement range when the separating piece is perpendicular to the load-carrying surface of the chain plate. The separating piece is blocked by the bent stop rod and tilted relative to the load-carrying surface of the chain plate.

[0007] The connecting piece and the separating piece are movably connected in a slot - card manner. The separating piece can move relative to the connecting piece. During the process that the separating piece forms a swinging motion on the connecting piece, the partition plate thus obtains a bent overall posture or a flattened overall posture. On the carrying surface of the chain plate, the partition plate will present a flattened and erected state where the separating piece is perpendicular to the carrying surface of the chain plate, or a bent and folded state where the separating piece is inclined to the carrying surface of the chain plate. Since the separating piece and the connecting piece are tightly movably connected through the slot - card, this tight connection relationship can keep the separating piece in a relative position to the connecting piece, so as to keep the partition plate in a bent or flattened overall posture and play a self - locking function.

[0008] The transformation between the flattened and erected state and the bent and folded state of the partition plate only needs the separating piece to swing relative to the connecting piece. The bending stop rod is used to change the relative position between the separating piece and the connecting piece, but it is only limited to promoting the partition plate to change from the flattened and erected state to the bent and folded state in a blocking manner. In this way, the partition plate will be in the bent and folded state when passing through the bending stop rod in the flattened and erected state. Compared with the prior art where the partition plate always stands upright on the conveying surface, the space that can be released by the partition plate that can enter the bent and folded state in this technical solution ensures that the space below the goods channel will not be occupied too much due to the partition plate being in the flattened and erected state. The vacated space can be used to place items in the adjacent lower goods channel, thus improving the utilization efficiency of the internal space of the vending machine.

[0009] The process of the partition plate changing from the flattened and erected state to the bent and folded state is a process in which an external force drives the separating piece to swing relative to the connecting piece. The position where this state changes is located at the turning part of the chain. The state - changing position is set here because this is the position where the item leaves the goods channel. Another reason is that the partition plate, as an extended structure at the end of the support component at this position, can extend the conveying range of the goods channel outward, so that the output item is not affected by the adjacent left - right or up - down goods channels, ensuring the smooth output of the item.

[0010] The optimized slot - card structure is that each end of the connecting piece is provided with a chute, and each end of the separating piece is provided with a rotating shaft corresponding to the chute. The separating piece is movably connected to the connecting piece by embedding the rotating shaft into the chute. This slot - card structure can bring a stable connection structure for the partition plate and a reliable clamping effect at the chute. This clamping effect is used to establish and maintain a tight connection relationship between the rotating shaft of the separating piece and the connecting piece.

[0011] Although a tight connection relationship between the separating piece and the connecting piece is established through the slot - card structure, and in the natural state, the partition plate relies on its own self - locking function to maintain a bent overall posture or a flattened overall posture, the degree of self - locking for the flattened overall posture is limited, that is, the performance in maintaining the flattened and erected state of the partition plate needs to be improved. For this reason, the present invention provides three preferred structures for this requirement.

[0012] First, a limiting surface is provided on the connecting piece. The limiting surface is located outside the area in the middle of the two sliding grooves. A restricted surface corresponding to the limiting surface is provided on the side surface of the separating piece. The width of the restricted surface is less than or equal to the diameter of the rotating shaft. The separating piece is connected to the limiting surface through the restricted surface to maintain a relative position perpendicular to the loading surface of the chain plate. When the limiting surface and the restricted surface are mutually attached, the separator plate is in a flattened and erected state, and the restricted surface is located above the limiting surface. After an external force drives the separating piece and overcomes the frictional force between the separating piece and the connecting piece, the relative position between the separating piece and the connecting piece can be changed. This structure for improving the self-locking degree has the advantages of being easy to design and easy to obtain.

[0013] Second, a limiting protrusion is provided on the separating piece, and a limiting groove corresponding to the limiting protrusion is provided on the connecting piece. The separating piece is embedded in the limiting groove through the limiting protrusion to maintain a relative position perpendicular to the loading surface of the chain plate. When the limiting protrusion is embedded in the limiting groove, the separator plate is in a flattened and erected state, and the limiting protrusion is located above the limiting groove. After an external force drives the separating piece and overcomes the frictional force between the separating piece and the connecting piece, the relative position between the separating piece and the connecting piece can be changed. Since the clamping action of the connecting piece on the separating piece at the sliding groove also drives the separating piece to be squeezed towards the limiting groove, thus, even when the limiting protrusion is worn or the limiting protrusion slightly deviates from the limiting groove, it will be automatically moved towards the position of the limiting groove with less resistance under the aforementioned squeezing trend, that is, automatically embedded in the limiting groove without targeted alignment operation. This structure for improving the self-locking degree has the advantages of accurate positioning and strong self-adaptability.

[0014] Third, a blocking surface is provided on the connecting piece. The blocking surface is located downstream of the separating piece in the swinging direction from the straight part to the turning part. The separating piece restricts the movement range of the separating piece relative to the connecting piece through the blocking surface to maintain a relative position perpendicular to the loading surface of the chain plate. The blocking surface restricts the swinging range of the separating piece on the connecting piece, and the position where the blocking surface is located is the limit position of the swinging of the separating piece. In this limit position, the separator plate is in a flattened and erected state. In the case of having a blocking surface, the swinging range of the separating piece is distributed on one side of the connecting piece. In the case of not having a blocking surface, the swinging range of the separating piece is distributed on both sides of the connecting piece. Therefore, in addition to setting the limit position of the separating piece so that the separating piece maintains a flattened and erected state perpendicular to the loading surface of the chain plate, the blocking surface also configures the state where the separating piece is inclined to the loading surface of the chain plate on one side of the connecting piece.

[0015] The above three structures can greatly increase the performance of the chain plate in maintaining the flat and upright state of the partition plate. The three structures will not interfere with each other. In addition to the three structures being designed on the chain plate in a separate manner, any two of them can be designed in combination on the chain plate, or all three can be designed on the chain plate. In this way, the overall design of superimposing multiple holding structures is more conducive to maintaining the flat and upright state of the partition plate.

[0016] The bending stopper remains stationary relative to the support assembly. After the moving chain plate passes through the area where the bending stopper is located, the upright partition plate is flattened and blocked by the bending stopper. The partition changes its position relative to the connecting member accordingly, and the partition plate changes from a flat overall posture to a bent overall posture. In order to allow the partition plate to undergo this change process in a gradual manner, the bending stopper is provided with a preliminary bending guide end and a deep bending guide end. The distance from the preliminary bending guide end to the center of the turning part is greater than the distance from the deep bending guide end to the center of the turning part. The preliminary bending guide end and the deep bending guide end are arranged separately in the direction around the center of the turning part. The deep bending guide end is located downstream of the preliminary bending guide end in the swinging direction from the straight part to the turning part. The distance from the preliminary bending guide end to the deep bending guide end is less than the length of the partition. The partition first contacts the preliminary bending guide end, and after being blocked by the preliminary bending guide end, the partition is in a small tilt. The partition then contacts the deep bending guide end, and after being blocked by the deep bending guide end, the partition is in a large tilt. Bending the partition plate in stages can avoid bending the partition plate in one go and thus causing a huge impact, thereby increasing the number of contacts in exchange for a low-impact bending operation.

[0017] The technical solution also provides a bending stopper rod structure that can conveniently provide a preliminary bending guide end and a deep bending guide end, that is, the cross section of the bending stopper rod is L-shaped.

[0018] The separator plate at the bend of the chain serves as an extension of the load-bearing surface of the chain plate in the straight portion, and can extend the conveying range of the cargo aisle outward. The extension function of the separator plate here is based on the fact that the items are blocked by the separator plate at the bend during the overturning process, forcing the items to fall to an area far away from the cargo aisle. In order to prevent the items from flipping over after overturning, the flattened upright state of the separator plate needs to be maintained until the items are easily supported by the separator plate and slide along the separator plate, so that the items will receive a more active guiding effect from the separator plate when they slide down the separator plate. In order to achieve this output effect, the direction from the center of the bend to the initial bend guide end is inclined to the straight portion. When the separator plate is blocked by the initial bend guide end, the spatial posture change process experienced by the separator plate can just provide the aforementioned guiding effect.

[0019] The conveying surface of the goods channel is composed of the load-carrying surface of the chain plates. The partition plates form a partitioning effect on the conveying surface, facilitating the separate placement of items. To improve the flexibility when the goods channel receives items, the chain plates are provided with load-carrying plates, the partition plates are movably installed on the load-carrying plates, positioning holes are provided on the load-carrying plates, positioning protrusions are provided on the connecting pieces, and the connecting pieces are movably connected to the load-carrying plates by embedding the positioning protrusions into the positioning holes. The partition plates on adjacent chain plates can obtain spacing adjustment by inserting into different positioning holes, so that the conveying surface can be flexibly adjusted during use, greatly improving the use efficiency of the conveying surface.

[0020] Since the partitioning effect of the partition plates is reflected in the direction along the chain, the positioning holes are arranged at equal intervals in the direction of the parallel straight part, so as to ensure that the adjustability of the layout space on the chain plates is consistent with the conveying direction of the conveying surface of the goods channel.

[0021] The present invention adopts the above technical solution: a foldable partition plate is provided on the goods channel. The partition plate can participate in the conveying operation in a flattened and erected state and can also vacate space in a bent and folded state, effectively reducing the space occupied by the goods channel operation, and improving the utilization efficiency of the internal space of the vending machine.

[0036] The first embodiment of the present invention is as Figures 1 to 13 shown.

[0037] The goods channel includes a support assembly 1, a load-carrying assembly, a drive assembly, and a bent stop bar 19.

[0038] The support assembly 1 is provided with a profile, an active-end support member, and a driven-end support member. The profile is of an overall flat structure and has 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 member is installed at one end of the profile, and the driven-end support member is installed at the other end of the profile. Rotatable gears are provided on both the active-end support member and the driven-end support member, and the movement range of the transmission teeth of the gears is located in the extending direction of the groove. The drive assembly is provided with a motor and a speed reduction structure, and a rotating shaft 16 serving as a power output end is provided on the drive assembly. The rotating shaft 16 is connected to the gear on the active-end support member, and thus the drive assembly provides power to the load-carrying assembly from the active-end support member.

[0039] The load-carrying assembly includes a chain 2 and a chain plate 3. The chain 2 is installed on the support assembly 1, and the chain 2 is connected to the gear. After the chain 2 is stretched and unfolded in the vertical direction, it forms a structure with both ends being arc-shaped and the middle being straight. The arc-shaped part of the chain 2 is formed by following the bend of the gear, and this part is the bending part of the chain 2. The straight structure of the chain 2 is the straight part of the chain 2. The two straight parts of the chain 2 are distributed vertically, and the straight part of the chain 2 located above is embedded in the groove located above.

[0040] The chain plate 3 is composed of a load-carrying plate 4 and a partition plate 8.

[0041] The load-carrying plate 4 is a flat plate-like structure. On one side of the load-carrying plate 4, there is a clamping part 6 for connecting with the link of the chain 2. The clamping part 6 is two convex structures protruding from one side of the load-carrying plate 4, and the link is embedded between the two convex structures. The load-carrying plate 4 is provided with straight-arranged positioning holes 7, and these positioning holes 7 are used for the load-carrying plate 4 to be combined with the partition plate 8. The partition plate 8 includes a connecting part 9 and a partitioning part 15, and the connecting part 9 and the partitioning part 15 are movably connected in a slot way. Specifically, this slot structure is that on one side of the connecting part 9, each end of the connecting part 9 is provided with a chute 10, and each end of the partitioning part 15 is provided with a rotating shaft 16 corresponding to the chute 10. The partitioning part 15 is movably connected with the connecting part 9 by embedding the rotating shaft 16 into the chute 10. After the two are combined in this way, the rotating shaft 16 is clamped in the chute 10. On the other side of the connecting part 9, the connecting part 9 is provided with positioning protrusions 11 corresponding to the positioning holes 7 on the load-carrying plate 4. The connecting part 9 is movably connected with the load-carrying plate 4 by embedding the positioning protrusions 11 into the positioning holes 7. When disassembling, only need to pull out the connecting part 9 from the load-carrying plate 4 with force; the partition plate 8 is assembled onto the load-carrying plate 4 from the other side of the load-carrying plate 4, and the surface on the other side of the load-carrying plate 4 is the load surface 5. After assembly, the partition plate 8 protrudes on the side of the load-carrying plate 4 where the load surface 5 is located, and the connecting part 9 is connected with the load surface 5. After the link plate 3 is combined with the chain 2, when the partitioning part 15 is forcefully pulled, relative movement will occur between the partitioning part 15 and the connecting part 9. As the direction of the external force changes, a process of the partitioning part 15 swinging on the connecting part 9 will be formed. After the external force disappears, the relative position between the partitioning part 15 and the connecting part 9 will be maintained due to the reason that the rotating shaft 16 is clamped by the connecting part 9 in the groove, presenting a self-locking state; in addition, the positioning holes 7 are arranged at equal intervals in the direction of the parallel straight part. Different relative positions between the partitioning part 15 and the connecting part 9 enable the partition plate 8 to obtain a bent overall posture or a flattened overall posture. The partition plate 8 on the load surface 5 of the link plate 3 will present a flattened and erected state where the partitioning part 15 is perpendicular to the load surface 5 of the link plate 3, or a bent and retracted state where the partitioning part 15 is inclined to the load surface 5 of the link plate 3.

[0042] In order to obtain a more stable flattened and erected state of the partition plate 8, the structure of the partition plate 8 in this embodiment has been optimized in the following three aspects. The first structural optimization. The connecting member 9 is provided with a limiting surface 12 having a planar structure. The limiting surface 12 is located on the side of the connecting member 9 where the groove is provided. However, the limiting surface 12 is located outside the region in the middle of the two sliding grooves 10, that is, they are not on the same horizontal plane. The side surface of the partition member 15 is provided with a restricted surface 17 corresponding to the limiting surface 12 and having a planar structure. The restricted surface 17 is located on the side of the partition member 15 where the rotating shaft 16 is provided. The width of the restricted surface 17 is less than or equal to the diameter of the rotating shaft 16. After the partition member 15 rotates on the connecting member 9, the limiting surface 12 and the restricted surface 17 can be mutually attached, that is, connected. At this time, the partition plate 8 is perpendicular to the loading surface 5, so that the partition member 15 maintains a relative position perpendicular to the loading surface 5 of the chain plate 3 by connecting the restricted surface 17 to the limiting surface 12. The second structural optimization, which is combined with the first structural optimization. The partition member 15 is provided with a limiting protrusion 18 protruding from the surface of the restricted surface 17. The connecting member 9 is provided with a limiting groove 13 corresponding to the limiting protrusion 18. The limiting grooves 13 are distributed at the part of the connecting member 9 where the limiting surface 12 is provided, and the orientation of the limiting grooves 13 is the same as that of the limiting surface 12. When the limiting surface 12 and the restricted surface 17 can be mutually attached, that is, in the state where the partition plate 8 is perpendicular to the loading surface 5, the limiting protrusion 18 will be embedded in the limiting groove 13, so that the partition member 15 maintains a relative position perpendicular to the loading surface 5 of the chain plate 3 by the limiting protrusion 18 being embedded in the limiting groove 13. The third structural optimization, which is also combined with the previous two. The connecting member 9 is provided with a blocking surface 14. Unlike the limiting grooves 13 that are concentrated at the position of the limiting surface 12, the blocking surface 14 is distributed at a position higher than the limiting surface 12, and the direction in which the blocking surface 14 plays a blocking role intersects with the orientation of the limiting surface 12. The blocking surface 14 is used to limit the swinging range of the partition member 15 on the connecting member 9. The position where the blocking surface 14 is located is the limit position of the swinging of the partition member 15. This limit position is exactly the position where the partition plate 8 is in the flattened and erected state. Therefore, this determines that the position distribution of the blocking surface 14 relative to the partition member 15 has particularity. It must be that the blocking surface 14 is located downstream of the partition member 15 in the swinging direction from the straight part to the turning part. When the partition member 15 is in the limit position, the partition member 15 restricts the movement range of the partition member 15 relative to the connecting member 9 through the blocking surface 14 and maintains a relative position perpendicular to the loading surface 5 of the chain plate 3. The above three optimized structures are combined together and do not interfere with each other. Generally, they can greatly improve the performance of the chain plate 3 in maintaining the flattened and erected state of the partition plate 8.

[0043] The link plates 3 are continuously distributed on the chain 2, and the distributed length is less than the length of the chain 2. The distribution range of the link plates 3 just covers a straight part, so that the link plates 3 located above the support assembly 1 can be used to place items. The swinging direction of the partition 15 on the connecting member 9 is in the same plane as the extending direction of the straight part. When the partition plate 8 is in the flattened and erected state, it can provide a structural basis for the efficient use of space for placing items; when the partition plate 8 is in the bent and folded state, it does not have the structural basis for placing items. The partition plate 8 in the flattened and erected state is perpendicular to the loading surface 5 of the loading plate 4.

[0044] When implementing this technical solution, the bent stop rod 19 is installed on the tray, and multiple cargo channels are also installed on the tray. The same bent stop rod 19 can serve multiple cargo channels, so that the bent stop rod 19 remains stationary relative to the support assembly 1.

[0045] The bent stop rod 19 is located at the turning part of the chain 2. The cross-section of the bent stop rod 19 is L-shaped. The bent stop rod 19 is provided with a preliminary bending guide end 20 and a deep bending guide end 21. When the partition plate 8 is in the flattened and erected state, the partition 15 is perpendicular to the loading surface 5 of the link plate 3. After the chain 2 moves in this state, the partition 15 will be blocked by the bent stop rod 19. Therefore, the position where the bent stop rod 19 is located intersects with the movement range of the partition 15 when it is perpendicular to the loading surface 5 of the link plate 3. Finally, the partition 15 is tilted relative to the loading surface 5 of the link plate 3 by the blockage of the bent stop rod 19.

[0046] The distance from the preliminary bending guide end 20 to the center of the turning part is greater than the distance from the deep bending guide end 21 to the center of the turning part. The preliminary bending guide end 20 and the deep bending guide end 21 are arranged separately in the direction around the center of the turning part, and the deep bending guide end 21 is located downstream of the preliminary bending guide end 20 in the swinging direction from the straight part to the turning part. The distance from the preliminary bending guide end 20 to the deep bending guide end 21 is less than the length of the partition 15. The direction from the center of the turning part to the preliminary bending guide end 20 is inclined to the straight part. The partition 15 first contacts the preliminary bending guide end 20 in the flattened and erected state. The preliminary bending guide end 20 blocks the partition 15 from following the movement of the chain 2. Then, the partition 15 is squeezed by the preliminary bending guide end 20 and changes its position relative to the connecting member 9. After being blocked by the preliminary bending guide end 20, the partition 15 is in a slightly tilted state; the partition 15 then contacts the deep bending guide end 21. After being blocked by the deep bending guide end 21, the partition 15 is in a greatly tilted state. Finally, the partition 15 leaves the bent stop rod 19 in the bent and folded state.

[0047] In the initial state, the straight part of the chain 2 located above the profile is covered with chain plates 3, and the partition plates 8 on the chain plates 3 are perpendicular to the loading surface 5 of the loading plate 4, and the partition plates 8 are in a flat and upright state. When in use, the items are placed on the chain plates 3, and the items are supported by the loading plate 4 and separated by the partition plates 8. When the cargo lane responds to the operation command to output the items outward, the chain 2 operates and drives the chain plates 3 to move toward the turning part where the bending baffle rod 19 is provided. After the items enter the turning part from the straight part along with the chain plates 3, the items tilt accordingly, and the overturned items are guided by the partition plates 8 located in front of the items and leave the cargo lane. Then, the partition plates 8 enter the position of the bending baffle rod 19 in a flat and upright state, and finally leave the bending baffle rod 19 in a bent and retracted state. To restore to the initial state, the chain 2 needs to be reversed, so that all the partition plates 8 in the bent and retracted state pass through the bent stop rod 19, and the connecting piece 9 is pulled at the straight position to make the partition plates 8 on the chain plate 3 return to the flat and upright state.

[0048] The partition plate 8 above the cargo aisle is in a flat and upright state, and the partition plate 8 below the cargo aisle is in a bent and folded state. The space required for the entire cargo aisle operation is significantly smaller than the space required for the cargo aisle operation in which the partition plate is always in a flat and upright state.

[0063] In the above embodiments, the chain can be covered with chain plates. The chain does not need to rotate in the reverse direction to return to the initial state, only needs to move unidirectionally. The partition plate in the bent and folded state below the profile enters the straight part above the profile from another turning part, and the connecting piece is pulled at the straight part to cause the partition plate on the chain plate to return to the flattened and erected state. Other embodiments can be obtained therefrom.

[0064] In the above embodiments, the installation structure of the bent stop bar can also be changed, and the bent stop bar can be combined with the support assembly. For example, the bent stop bar is fixedly connected to the profile, so as to ensure that the bent stop bar remains stationary relative to the support assembly. Other embodiments can be obtained therefrom.
