Description

Technical Field

[0001] This application relates to the field of goods sorting technology, and in particular to a sorting cart and sorting equipment. Background Technology

[0002] In existing technologies, sorting equipment using automated guided vehicles (AGVs) involves installing a transfer component on the sorting vehicle and mounting it onto a track, allowing the vehicle to run along a predetermined path. When sorting items, the items to be sorted are placed on the transfer component of the sorting vehicle. The vehicle is then controlled to move along the track to the target sorting slot on one side of the track. Afterward, the transfer component on the sorting vehicle transfers the items to the target sorting slot to complete the sorting process.

[0046] This application provides a sorting cart and sorting equipment. These will be described in detail below.

[0047] First, this application provides a sorting cart.

[0048] Figure 1 This is a schematic diagram of the structure of one embodiment of the sorting cart provided in this application. Figure 1 As shown, the sorting cart 100 includes a support 110 and a transmission assembly 120. The transmission assembly 120 is mounted on the support 110 and has a transmission surface for transporting items. When using the sorting cart 100 to sort items, the items to be sorted are first placed on the transmission surface of the transmission assembly 120. Then, the sorting cart 100 is controlled to move to the target sorting slot (not shown in the figure), so that the output end of the transmission assembly 120 corresponds to the target sorting slot. By controlling the operation of the transmission assembly 120, the items on the transmission surface of the transmission assembly 120 are transported to the target sorting slot, thus completing the sorting of items.

[0049] It should be noted that the sorting cart 100 in this application can be used in a sorting device or used independently. When the sorting cart 100 is used in a sorting device (not shown in the figure), the sorting device includes a sorting track (not shown in the figure), and the sorting cart 100 is slidably mounted on the sorting track. The transmission direction of the transmission component 120 on the sorting cart 100 forms an angle with the extension direction of the sorting track. Sorting slots are provided on one or both sides of the sorting track. When the sorting device sorts items using the sorting cart 100, the sorting cart 100, which contains items, can be controlled to move along the sorting track to the target sorting slot of the items, so that the output end of the transmission component 120 on the sorting cart 100 corresponds to the sorting slot. Then, the transmission component 120 is controlled to operate, so as to transfer the items on the transmission surface of the transmission component 120 to the target sorting slot, thus completing the sorting of the items.

[0050] When the sorting cart 100 is used alone, the sorting cart 100 can be an AGV (Automated Guided Vehicle). The AGV can move freely in the sorting area to reach the vicinity of different sorting slots, so that the items on the AGV can be transferred to the target sorting slot through the transfer component 120.

[0051] It should be noted that the sorting cart 100 in this embodiment is not limited to sorting items, but can also be used for transferring, transporting, etc., and is not limited here.

[0052] To prevent items on the sorting cart 100 from being thrown off the sorting and unloading conveyor assembly 120 due to centrifugal force during its movement around corners, such as... Figure 1 , Figure 3 and Figure 4 As shown, the sorting cart 100 also includes a limiting structure 130, which is mounted on the support 110. The limiting structure 130 is located at one end of the transmission direction of the transmission assembly 120. The limiting structure 130 includes a limiting member 131 and a driving mechanism 132. The driving mechanism 132 is connected to the limiting member 131 to drive the limiting member 131 to move between a limiting position and an avoidance position.

[0053] When the limiting member 131 is in the limiting position, the limiting member 131 is used to abut against the items on the transmission surface of the transmission component 120 to restrict the items on the transmission surface from moving along the transmission direction of the transmission component 120, thereby avoiding the problem that the items on the sorting cart 100 are thrown off the transmission component 120 under the action of centrifugal force when the sorting cart 100 turns.

[0054] When the limiting member 131 is in the avoidance position, the limiting member 131 is used to avoid the items on the transmission surface of the transmission component 120, so that when the sorting trolley 100 runs to the target sorting slot corresponding to the item, the transmission component 120 can transfer the item on the transmission surface to the target sorting slot.

[0055] It should be noted that the movement of the limiting member 131 between the limiting position and the avoidance position can be that the limiting member 131 slides between the avoidance position and the limiting position, or that the limiting member 131 rotates between the limiting position and the avoidance position. In addition, the limiting member 131 can also slide and rotate simultaneously between the avoidance position and the limiting position.

[0056] When the limiting member 131 is in the limiting position, such as Figure 4 As shown, at least a portion of the limiting member 131 is located directly above the transmission surface. Thus, the portion of the limiting member 131 located directly above the transmission surface can abut against the items on the transmission surface to restrict the items from moving along the transmission direction of the transmission assembly 120, thereby preventing items on the sorting cart 100 from being thrown out from the side of the transmission assembly 120 where the limiting member 131 is located under the action of centrifugal force when the sorting cart 100 turns.

[0057] Alternatively, when the limiting member 131 is in the limiting position, the limiting member 131 is located on one side of the transmission direction of the transmission assembly 120, and at least a portion of the limiting member 131 extends out of the transmission surface. Thus, the portion of the limiting member 131 extending out of the transmission surface can abut against the items on the transmission surface to restrict the movement of the items along the transmission direction of the transmission assembly 120, thereby preventing items on the sorting cart 100 from being thrown out from the side of the transmission assembly 120 where the limiting member 131 is located under centrifugal force when the sorting cart 100 is turning.

[0058] Optionally, when the limiting member 131 is in the avoidance position, such as Figure 3 As shown, the limiting member 131 retracts to one side of the transmission surface along the width direction of the transmission assembly 120. At this time, the limiting member 131 is not located directly above the transmission surface, and the limiting member 131 is offset in the transmission direction of the transmission assembly 120. Thus, the limiting member 131 can avoid the items on the transmission surface, so that the transmission assembly 120 can transmit the items out in the transmission direction.

[0059] Alternatively, when the limiting member 131 is in the avoidance position, the limiting member 131 retracts below the transmission surface. Thus, the limiting member 131 can avoid items on the transmission surface, allowing the transmission assembly 120 to transmit the items along the transmission direction.

[0060] In this embodiment, when the limiting member 131 is in the limiting position, at least a portion of the limiting member 131 is located directly above the transmission surface, or the limiting member 131 is located on one side of the transmission direction of the transmission assembly 120, and at least a portion of the limiting member 131 extends out of the transmission surface. This allows the limiting member 131 to abut against the items on the transmission surface, restricting the movement of the items along the transmission direction of the transmission assembly 120. This prevents items on the sorting cart 100 from being thrown out from the side of the transmission assembly 120 where the limiting member 131 is located under centrifugal force when the sorting cart 100 is turning.

[0061] Meanwhile, when the limiting member 131 is in the avoidance position, the limiting member 131 retracts to one side of the transmission surface along the width direction of the transmission assembly 120, or the limiting member 131 retracts to below the transmission surface, so that the limiting member 131 can avoid the items on the transmission surface, so that the transmission assembly 120 can transmit the items out along the transmission direction.

[0062] It should be noted that there are multiple combinations of the two states of the limiting member 131 when it is in the limiting position and the two states when it is in the avoidance position. It is sufficient that the limiting member 131 can limit the items on the transmission surface when it is in the limiting position and can avoid the items on the transmission surface when it is in the avoidance position.

[0063] For example, when the limiting member 131 is in the limiting position, at least part of the limiting member 131 is located directly above the transmission surface, and when the limiting member 131 is in the limiting position, the limiting member 131 retracts to one side of the transmission surface along the width direction of the transmission assembly 120.

[0064] Alternatively, when the limiting member 131 is in the limiting position, at least a portion of the limiting member 131 is located directly above the transmission surface, and when the limiting member 131 is in the avoidance position, the limiting member 131 retracts to below the transmission surface.

[0065] Alternatively, when the limiting member 131 is in the limiting position, the limiting member 131 is located on one side of the transmission direction of the transmission component 120, and at least part of the limiting member 131 extends out of the transmission surface, and when the limiting member 131 is in the avoidance position, the limiting member 131 retracts to one side of the transmission surface along the width direction of the transmission component 120.

[0066] In addition, when the limiting member 131 is in the limiting position, the limiting member 131 is located on one side of the transmission direction of the transmission component 120, and at least part of the limiting member 131 extends out of the transmission surface, and when the limiting member 131 is in the avoidance position, the limiting member 131 retracts to below the transmission surface.

[0067] like Figure 3 and Figure 4As shown, the limiting structure 130 includes a base 135 mounted on a bracket 110, and a limiting member 131 rotatably connected to the base 135. The limiting member 131 can rotate relative to the base 135 and has a limiting position and a clearance position. A drive mechanism 132 is disposed on the base 135 and connected to the limiting member 131 to drive the limiting member 131 to rotate between the limiting position and the clearance position. By mounting the drive mechanism 132 and the limiting member 131 on the base 135, during the assembly of the sorting cart 100, the base 135 can be directly mounted on the bracket 110, thus the limiting structure 130 can be mounted entirely on the bracket 110, improving the assembly efficiency of the sorting cart 100.

[0068] The limiting member 131 is positioned at an angle to the transmission surface relative to the rotation axis of the base 135. When the driving mechanism 132 drives the limiting member 131 to rotate to the limiting position, part of the limiting member 131 is located directly above the transmission surface; when the driving mechanism 132 drives the limiting member 131 to rotate to the avoidance position, the limiting member 131 retracts to one side of the transmission surface along the width direction of the transmission assembly 120.

[0069] The angle between the rotation axis of the limiting member 131 relative to the base 135 and the transmission surface can be 90°, 80°, 60°, etc. When the angle between the rotation axis of the limiting member 131 relative to the base 135 and the transmission surface is 90°, the height of the limiting member 131 relative to the transmission surface will not change during the rotation of the limiting member 131 between the limiting position and the avoidance position.

[0070] In other embodiments, the axis of rotation of the limiting member 131 relative to the base 135 extends along the transmission direction of the transmission assembly 120. When the driving mechanism 132 drives the limiting member 131 to rotate to the limiting position, part of the limiting member 131 is located directly above the transmission surface; when the driving mechanism 132 drives the limiting member 131 to rotate to the clearance position, the limiting member 131 retracts upward or downward to one side of the transmission surface along the width direction of the transmission assembly 120.

[0071] The rotation axis of the limiting member 131 relative to the base 135 can be parallel to the transmission direction of the transmission component 120, or it can be at a certain angle to the transmission direction of the transmission component 120. It is only necessary to enable the limiting member 131 to rotate between the limiting position and the avoidance position.

[0072] like Figure 3 and Figure 4 As shown, the limiting member 131 is rod-shaped to provide a better limiting effect on the item when it is in the limiting position. One end of the limiting member 131 is hinged to the base 135, and the other end is a free end. The driving mechanism 132 is connected to the limiting member 131 to drive the limiting member 131 to rotate between the limiting position and the avoidance position.

[0073] In other embodiments, the limiting member 131 is provided in the shape of a plate or block, etc., as long as it can limit the item when it is in the limiting position and allow the item to be avoided when it is in the avoidance position.

[0074] like Figure 3 and Figure 4 As shown, the drive mechanism 132 includes a linkage assembly 133 and a drive assembly 134 connected to the base 135. The linkage assembly 133 is connected to the limiting member 131, and the drive assembly 134 is mounted on the base 135. The drive assembly 134 is connected to the linkage assembly 133 and drives the linkage assembly 133 to move, so that the linkage assembly 133 drives the limiting member 131 to rotate between a limiting position and a clearance position. The drive assembly 134 drives the limiting member 131 to rotate between the limiting position and the clearance position through the linkage assembly 133, which makes the structure of the drive mechanism 132 relatively simple and stable. It also allows the limiting member 131 to withstand greater impact force when in the limiting position, thereby improving the limiting ability of the limiting member 131 to limit items on the transmission surface.

[0075] One end of the limiting member 131 is hinged to the base 135, and a hinge portion 1311 extends out from one side of the limiting member 131. The connecting rod assembly 133 is hinged to the hinge portion 1311, so that when the driving member 1341 drives the connecting rod assembly 133 to move, the connecting rod assembly 133 can drive the limiting member 131 to rotate.

[0076] Optionally, the linkage assembly 133 includes a first linkage 1331 and a second linkage 1332. One end of the first linkage 1331 is hinged to the hinge portion 1311, and the other end of the first linkage 1331 is hinged to one end of the second linkage 1332. The other end of the second linkage 1332 is hinged to the base 135. The drive assembly 134 is connected to the first linkage 1331 to drive the first linkage 1331 to rotate, causing the first linkage 1331 to drive the limiting member 131 to rotate between a limiting position and an avoidance position.

[0077] It is understandable that the first link 1331, the second link 1332, the base 135, and the limiting member 131 can form a planar four-bar linkage structure. When the driving member 1341 drives the first link 1331 to rotate, the limiting member 131 can be driven to rotate stably between the limiting position and the avoidance position through the first link 1331.

[0078] It should be noted that the connection between the drive assembly 134 and the first link 1331 to drive the first link 1331 to rotate can be either that the drive assembly 134 is directly connected to the first link 1331 and drives the first link 1331 to rotate, or that the drive assembly 134 is indirectly connected to the first link 1331 through the second link 1332, and the drive assembly 134 drives the second link 1332 to rotate, thereby causing the second link 1332 to drive the first link 1331 to rotate.

[0079] Optionally, the drive assembly 134 includes a drive member 1341, a drive rod 1345, and a third link 1346. One end of the third link 1346 is hinged to the second link 1332 or the first link 1331, and one end of the drive rod 1345 is hinged to the other end of the third link 1346. The drive member 1341 is connected to the other end of the drive rod 1345 to drive the drive rod 1345 to extend and retract, so that the drive rod 1345 drives the second link 1332 or the first link 1331 to rotate through the third link 1346.

[0080] In this embodiment, since the drive rod 1345 moves by moving, while the first link 1331 moves by rotating, the drive rod 1345 is hinged to the first link 1331 or the second link 1332 via the third link 1346. This allows the drive rod 1345 to stably push the first link 1331 to rotate via the third link 1346, or to stably push the second link 1332 to rotate via the third link 1346, thereby causing the first link 1331 to rotate via the second link 1332.

[0081] Furthermore, when the drive rod 1345 is at its two extreme positions in the extension and retraction direction, the limiting member 131 is respectively located in the limiting position and the avoidance position under the drive of the drive rod 1345, thereby making the structure of the limiting member 131 more stable in the limiting position, able to withstand greater impact force, and better limiting ability for the item.

[0082] Optionally, the drive member 1341 includes a telescopic rod 1342 extending along the length direction of the drive rod 1345, and a telescopic drive structure 1343 mounted on the base 135. One end of the telescopic rod 1342 is connected to the other end of the drive rod 1345, and the telescopic drive structure 1343 is connected to the other end of the telescopic rod 1342 to drive the telescopic rod 1342 to slide along the length direction of the drive rod 1345, thereby causing the telescopic rod 1342 to drive the drive rod 1345 to slide along the length direction of the drive rod 1345.

[0083] Optionally, the telescopic rod 1342 is a magnetic rod, which is slidably connected to the driving member 1341 along the length of the driving rod 1345. The telescopic driving structure 1343 includes a coil (not shown in the figure) sleeved on the magnetic rod. When the coil is energized, it can generate a magnetic field to drive the magnetic rod to slide along the length of the driving rod 1345. The structure is relatively simple.

[0084] The magnetic rod has an extended position and a retracted position. When the magnetic rod slides to the extended position (e.g., Figure 4 As shown), the magnetic rod sequentially drives the first connecting rod 1331 to rotate via the drive rod 1345 and the third connecting rod 1346, causing the first connecting rod 1331 to drive the limiting member 131 to rotate to the limiting position. When the magnetic rod slides to the retracted position (as shown), Figure 3 As shown, the magnetic rod drives the first link 1331 to rotate through the drive rod 1345 and the third link 1346 in sequence, so that the first link 1331 drives the limiting member 131 to rotate to the avoidance position.

[0085] The drive unit 1341 also includes an elastic element (not shown in the figure), one end of which is connected to the base 135 or the telescopic drive structure 1343, and the other end of which is connected to the magnetic rod to apply an elastic force to the magnetic rod to make the magnetic rod slide in the direction from the retracted position to the extended position.

[0086] When the conductive coil is energized, it drives the magnetic rod to slide from the extended position to the retracted position until the magnetic rod reaches the retracted position. When the conductive coil of the driving component 1341 is de-energized, the elastic force applied by the elastic element to the magnetic rod causes it to slide from the retracted position to the extended position until it reaches the extended position. This avoids the conductive coil's lifespan being reduced or its energy consumption being excessive due to prolonged energization.

[0087] In other embodiments, the drive element 1341 may not include the elastic element. By changing the direction of the current in the conductive coil, the sliding direction of the magnetic rod can be changed, thereby allowing the magnetic rod to slide back and forth between the extended position and the retracted position.

[0088] Specifically, the hinge portion 1311 on the limiting member 131 is located at the end where the limiting member 131 is hinged to the base 135, and the hinge portion 1311 is located on one side of the limiting member 131 along the rotation direction from the clearance position to the limiting position. One end of the first connecting rod 1331 is hinged to the hinge portion 1311, and the other end of the first connecting rod 1331 is hinged to one end of the second connecting rod 1332, and the other end of the second connecting rod 1332 is hinged to the base 135. The third connecting rod 1346 is located on the side of the first connecting rod 1331 and the second connecting rod 1332 away from the transmission assembly 120, and one end of the third connecting rod 1346 is hinged to the hinge point of the second connecting rod 1332 and the first connecting rod 1331, so that one end of the third connecting rod 1346 is simultaneously hinged to the second connecting rod and the first connecting rod 1331. The third connecting rod 1346 extends along the width direction of the transmission assembly 120. One end of the drive rod 1345 is hinged to the other end of the third connecting rod 1346. The extension and retraction direction of the drive rod 1345 is parallel to the width direction of the transmission assembly 120. The base 135 is a sheet metal structure and is connected to the bracket 110 by screws. A bearing 136 is provided on the base 135, and the bearing 136 is sleeved on the drive rod 1345 to allow the drive rod 1345 to slide in connection with the base 135. One end of the telescopic rod 1342 is connected to the other end of the drive rod 1345 through a floating joint 1347, so that one end of the telescopic rod 1342 can have a certain amount of movement relative to the other end of the drive rod 1345.

[0089] The rotation axis of the limiting member 131 of the third link 1346 relative to the base 135, the hinge axis of the first link 1331 and the limiting member 131, the hinge axis of the first link 1331 and the second link 1332, the hinge axis of the second link 1332 and the base 135, the hinge axis of one end of the third link 1346 and the hinge point of the second link 1332 and the first link 1331, and the hinge axis of the third link 1346 and the drive rod 1345 are all parallel and perpendicular to the transmission surface of the transmission assembly 120.

[0090] In other embodiments, the telescopic drive structure 1343 includes a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0091] In other embodiments, the drive assembly 134 includes a motor mounted on the base 135 and connected to the second link 1332 to drive the second link 1332 to rotate. Alternatively, the motor shaft is directly connected to the limiting member 131 to drive the limiting member 131 to rotate. Alternatively, the motor shaft is connected to the limiting member 131 through an intermediate transmission mechanism such as a gear set or worm gear to drive the limiting member 131 to rotate.

[0092] like Figure 1 and Figure 2As shown, the limiting structure 130 is disposed on one side of the transmission component 120 in the width direction to facilitate the installation of the limiting structure 130. Alternatively, there may be multiple limiting structures 130, distributed on both sides of the transmission component 120 in the width direction, to facilitate the installation of the limiting structure 130 while further improving the limiting effect of the limiting structure 130 on the item.

[0093] like Figure 1 and Figure 2 As shown, the support 110 is provided with limiting structures 130 at both ends along the transmission direction of the transmission assembly 120. Thus, the limiting structures 130 at both ends of the support 110 along the transmission direction of the transmission assembly 120 can simultaneously limit the items on both sides along the transmission direction of the transmission assembly 120, and prevent the items from falling off the transmission assembly 120 under the action of centrifugal force when the sorting trolley 100 turns in different directions.

[0094] In other embodiments, the limiting member 131 is slidably connected to the base 135 along the width direction of the transmission assembly 120. When the limiting member 131 slides to the point where at least part of the limiting member 131 is directly above the transmission surface, or when the limiting member 131 is located on one side of the transmission direction of the transmission assembly 120 and at least part of the limiting member 131 extends out of the transmission surface, the limiting member 131 is in a limiting position. When the limiting member 131 slides to the point where it is retracted to one side of the transmission surface along the width direction of the transmission assembly 120, the limiting member 131 is in an avoidance position.

[0095] The drive assembly 134 is connected to the limiting member 131 to drive the limiting member 131 to slide between a limiting position and an avoidance position. The drive assembly 134 includes a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, a gear and rack assembly, etc. The telescopic drive assembly 134 is mounted on the base 135, and its telescopic end is connected to the limiting member 131 to drive the limiting member 131 to slide along the width direction of the transmission assembly 120.

[0096] In other embodiments, the sliding direction of the limiting member 131 and the base 135 forms an angle with the transmission surface of the transmission assembly 120. When the limiting member 131 slides upward to the point where at least part of the limiting member 131 extends above the transmission surface, the limiting member 131 is in a limiting position; when the limiting member 131 slides downward to the point where it retracts below the transmission surface, the limiting member 131 is in an avoidance position.

[0097] The fact that at least part of the limiting member 131 extends above the transmission surface can mean that at least part of the limiting member 131 extends directly above the transmission surface, or that at least part of the limiting member 131 extends diagonally above the side of the transmission surface along the transmission direction of the transmission assembly 120. It is sufficient that the limiting member 131 can limit the items on the transmission surface.

[0098] The limiting member 131 can slide down to be recessed below the transmission surface. This can be either directly below the transmission surface or diagonally below it. As long as the height of the limiting member 131 is less than the height of the transmission surface, the limiting member 131 will not restrict the items on the transmission surface.

[0099] like Figure 1 and Figure 2 As shown, the sorting cart 100 includes multi-layer conveyor assemblies 120. This allows items to be placed on the conveying surface of the upper conveyor assembly 120 of the sorting cart 100, while the lower conveyor assembly 120 can be used to recycle empty pallets supporting the items. Alternatively, the height difference between adjacent conveyor assemblies 120 can be greater than the height of the items, and items can be placed on each conveyor assembly 120 to allow the sorting cart 100 to sort multiple items.

[0100] The sorting cart 100 includes a transfer assembly 120 with two, three, or more layers. Furthermore, the transfer directions of the multiple transfer assemblies 120 can be the same or different. Of course, the former makes it easier for the sorting cart 100 to sort items and collect empty pallets.

[0101] Optionally, each transmission component 120 is provided with a limit structure 130. This allows for the limiting of items on each transmission component 120.

[0102] like Figure 1 and Figure 2 As shown, a detection component 140 is provided on the support 110. This detection component 140 is used to detect the position of the item on the transmission surface of the transmission component 120. By detecting the position of the item on the transmission component 120 through the detection component 140, it is possible to determine whether the item on the sorting cart 100 is in a suitable position when the sorting cart 100 transports the item, or whether the item on the transmission component 120 is transmitted out by the transmission component 120 when the sorting cart 100 transmits the item to the sorting slot through the transmission component 120.

[0103] The detection component 140 is located on one side of the transmission component 120 in the width direction, so that the detection component 140 can detect the items on the transmission component 120, and the installation of the detection component 140 is also convenient.

[0104] There are multiple detection components 140, which are distributed sequentially along the transmission direction of the transmission component 120, thereby further improving the detection accuracy of the position of the item on the transmission component 120.

[0105] Optionally, the detection component 140 includes a photoelectric sensor to facilitate the detection of the position of the object. The photoelectric sensor may include diffuse reflection photoelectric sensors, through-beam photoelectric sensors, etc., and is not limited here.

[0106] Optionally, the sorting cart 100 includes a multi-layer transmission assembly 120, and each transmission assembly 120 is provided with a detection assembly 140, so that the items on each transmission assembly 120 can be detected.

[0107] like Figure 1 and Figure 2 As shown, the transmission assembly 120 includes multiple transmission rollers 121 rotatably connected to the support 110. The multiple transmission rollers 121 are distributed sequentially at intervals along the transmission direction of the transmission assembly 120. One end of each transmission roller 121 is provided with a drive sprocket 122, and the drive sprockets 122 on the multiple transmission rollers 121 are linked together by a chain (not shown in the figure). When one transmission roller 121 rotates, it can drive the other transmission rollers 121 to rotate synchronously together via the chain, thereby completing the transmission of the item. The length direction of the transmission rollers 121 extends along the width direction of the transmission assembly 120.

[0108] The transmission assembly 120 also includes a drive structure 123 mounted on the bracket 110. The drive structure 123 is connected to one of the transmission rollers 121 to drive the multiple transmission rollers 121 to rotate. Since the transmission sprockets 122 on the multiple transmission rollers 121 are linked by chains, when the drive structure 123 drives the corresponding transmission roller 121 to rotate, it can drive the other transmission rollers 121 to rotate synchronously through that transmission roller 121.

[0109] An oil receiving groove 111 is also provided on the support 110. The oil receiving groove 111 is located below the chain and extends along the length of the chain. It is understood that in order to reduce the friction between the chain and the drive sprocket 122, lubricating oil needs to be applied to the drive sprocket 122 and the chain. By providing an oil receiving groove 111 below the chain and extending the oil receiving groove 111 along the length of the chain, the lubricating oil applied to the drive sprocket 122 and the chain can drip into the oil receiving groove 111, thereby preventing the lubricating oil applied to the drive sprocket 122 and the chain from dripping onto other parts of the sorting cart 100 and causing contamination, or affecting the operational stability of the sorting cart 100.

[0110] Optionally, the drive sprocket 122 on the transmission roller 121 is a double-row sprocket to improve the connection stability between the drive sprocket 122 and the chain.

[0111] Specifically, such as Figure 1 and Figure 2As shown, the support 110 of the sorting cart 100 includes blocking portions 112 located on both sides of the conveying assembly 120 in the width direction. These blocking portions 112 protrude from the conveying surface of the conveying assembly 120, thereby limiting the items on the conveying assembly 120 and preventing them from falling along the width direction of the conveying assembly 120. The blocking portions 112 extend along the conveying direction of the conveying assembly 120 to provide a better limiting effect on the items on the conveying assembly 120.

[0112] The sorting cart 100 includes upper and lower layers of transmission components 120, with blocking portions 112 provided on both sides of each transmission component 120 in the width direction. A limiting structure 130 corresponding to each transmission component 120 is mounted on the blocking portion 112. A detection component 140 corresponding to each transmission component 120 is mounted on the blocking portion 112. Furthermore, the limiting structure 130 and the detection component 140 are distributed on opposite sides of the transmission component 120.

[0113] like Figure 1 As shown, the sorting cart 100 also includes a chassis 150, on which rollers 160 are mounted. The rollers 160 are rotatably mounted on the sorting track of the sorting equipment, so that the sorting cart 100 can move along the sorting track. The bracket 110 of the sorting cart 100 is mounted on the chassis 150. The bracket 110 includes support frames 113 distributed on both sides of the width direction of the transmission assembly 120, and the shielding part 112 is located on the support frame 113.

[0114] This application also proposes a sorting device, which includes a sorting cart. The specific structure of the sorting cart is as described in the above embodiments. Since this sorting device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0115] The sorting equipment includes a sorting track, on which a sorting trolley 100 is slidably mounted. Sorting slots are provided on one or both sides of the sorting track. When the sorting equipment sorts items using the sorting trolley 100, the sorting trolley 100, containing the items, can be controlled to move along the sorting track to the target sorting slot, aligning the output of the transmission component 120 on the sorting trolley 100 with the sorting slot. Then, the transmission component 120 is controlled to operate, transferring the items on its transmission surface to the target sorting slot, thus completing the sorting of the items.

[0116] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
