Description

Technical Field

[0001] The present application relates to the technical field of logistics sorting, and in particular to a flip-plate sorting trolley and a sorting system having the same. Background Art

[0002] Sorting systems are material handling systems that classify random, differently oriented items according to specific requirements. In recent years, the logistics industry has rapidly developed, and various automatic and semi-automatic sorting equipment has been developed and applied to actual sorting operations. Among them, flip-panel sorting carts are removable devices equipped with a reversible tray for carrying items. When the sorting cart brings the tray to a designated sorting location, it tilts the tray at a certain angle to unload the items on the tray into the corresponding container or other equipment.

[0003] In some related technologies, electromagnets are often installed on the trays of flip-plate sorting carts. When sorting items, it is necessary to electrically control the electromagnets to tilt the tray to one side, and then pour the items into the designated position. Since the sorting cart needs to move during the actual logistics sorting process, the electromagnets on the tray will also follow the movement. In this way, the design requirements for the wire structure connected to the electromagnets are high, otherwise it is easy to malfunction. Moreover, when such a sorting cart is applied to the actual sorting system, the electromagnets corresponding to each sorting cart need to be controlled separately, which will lead to a more complex overall wiring structure and a greater possibility of malfunction. Therefore, how to reduce the failure rate of flip-plate sorting carts is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a flip-plate sorting trolley and a sorting system having the same, so as to reduce the failure rate of the flip-plate sorting trolley. The specific technical solution is as follows:

[0005] An embodiment of the first aspect of the present application provides a flip-plate sorting trolley, comprising:

[0006] Base assembly;

[0007] a tray assembly, the tray assembly comprising a tray and a tray support, the first portion of the tray support being used to support the tray, the first end of the second portion of the tray support supporting the first portion of the tray support and being connected to the base assembly via a first hinge, such that the first portion of the tray support can rotate about the axial direction of the first hinge in a direction approaching the base assembly;

[0008] The locking assembly comprises a connecting shaft, a rotating member, a torsion spring, a limiting post, a locking block mounted on the second end of the second part of the tray bracket, and a lock buckle adapted to the locking block; the connecting shaft is fixed to the base assembly; the rotating member is rotatably sleeved on the connecting shaft; one end of the torsion spring is fixed to the base assembly or the connecting shaft, and the other end of the torsion spring is fixed to the rotating member; the lock buckle is arranged at the first end of the rotating member; the limiting post is fixed to the base assembly and is located between the locking block and the connecting shaft, and the limiting post is used to interfere with the first end of the rotating member to keep the lock buckle in a position to be locked with the locking block.

[0009] The cam is connected to the base assembly via a first hinge, and the second end of the cam is connected to the base assembly via a first hinge. The cam is connected to the base assembly via a first hinge, and the second end of the cam is connected to the base assembly via a first hinge. The cam is connected to the base assembly via a first hinge. The cam is connected to the base assembly via a first hinge. The weight of this side is greater, so when the locking assembly is in the unlocked state, the locking block provided at the second end of the second part of the tray bracket is no longer restricted by the lock buckle, so that the first part of the tray bracket can tilt toward the base assembly under the action of its own gravity, thereby pouring out the materials on the tray; at the same time, when the external force acting on the second end of the rotating member disappears, the rotating member will automatically rotate under the elastic action of the torsion spring to restore the deformation, and the first end of the rotating member is kept in a position that conflicts with the limit post through the obstruction of the limit post. Even if the lock buckle provided at the first end of the rotating member is reset to a position where it can be locked with the lock buckle, at this time, the first part of the tray bracket is rotated to reset the locking block provided at the second part of the tray bracket, so that the locking block and the lock buckle can be locked again. When the locking assembly is in the locked state, the locking block provided at the second end of the second part of the tray bracket is restricted by the lock buckle, so that the tray bracket is fixed and the tray assembly maintains horizontal balance. It can be seen that the flip-plate sorting trolley provided in the embodiment of the present application does not need to rely on electrical control in the process of realizing the tilting and resetting of its tray assembly, and there is no need to set up a more complicated wiring structure. Compared with the sorting trolley in which electromagnets are installed on the tray and the electromagnets are electrically controlled to tilt the tray, the flip-plate sorting trolley provided in the embodiment of the present application has a lower failure rate.

[0010] In some embodiments of the present application, the base assembly includes a fixed seat and a limit plate, one end of the limit plate is fixed to the fixed seat, and the other end of the limit plate is used to limit the maximum angle of rotation of the first part of the tray bracket around the axial direction of the first hinge close to the base assembly.

[0011] In some embodiments of the present application, the locking block is installed on a side of the second part of the tray bracket close to the base assembly, and one side of the locking block has an opening, and the end of the locking buckle is clamped in the opening to achieve locking with the locking block.

[0012] An embodiment of the second aspect of the present application provides a sorting system, including a flip-plate sorting trolley provided according to the embodiment of the first aspect of the present application.

[0013] The cam is connected to the base assembly via a first hinge, and the second end of the cam is connected to the base assembly via a first hinge, and the second end of the cam is connected to the base assembly via a first hinge. The weight of this side of the part is greater, so when the locking assembly is in the unlocked state, the locking block provided at the second end of the second part of the tray bracket is no longer restricted by the lock buckle, so that the first part of the tray bracket can tilt toward the base assembly under the action of its own gravity, thereby pouring out the materials on the tray; at the same time, when the external force acting on the second end of the rotating member disappears, the rotating member will automatically rotate under the elastic action of the torsion spring to restore the deformation, and the first end of the rotating member is kept in a position that conflicts with the limit post through the obstruction of the limit post, even if the lock buckle provided at the first end of the rotating member is reset to a position where it can be locked with the lock buckle. At this time, the first part of the tray bracket is rotated to reset the locking block provided at the second part of the tray bracket, so that the locking block and the lock buckle can be locked again. When the locking assembly is in the locked state, the locking block provided at the second end of the second part of the tray bracket is restricted by the lock buckle, so that the tray bracket is fixed and the tray assembly maintains horizontal balance. It can be seen that in the sorting system provided by the embodiment of the present application, its flip-plate sorting trolley does not need to rely on electrical control to realize the tilting and resetting of its tray assembly, and there is no need to set up a more complicated wiring structure. Compared with the sorting trolley that installs electromagnets on the tray and electrically controls the electromagnets to tilt the tray, the sorting system provided by the embodiment of the present application has a lower failure rate of its flip-plate sorting trolley, which makes the overall reliability of the sorting system higher.

[0014] In some embodiments of the present application, the sorting system also includes a body frame and a conveying mechanism arranged on the body frame, the conveying mechanism includes a circulating conveying chain arranged along at least one loading position and at least one sorting position, and the base assembly of the flip-type sorting trolley is connected to the circulating conveying chain by bolts.

[0015] In some embodiments of the present application, the sorting system further includes an unlocking switch arranged on the body frame opposite to each of the sorting positions, one unlocking switch corresponding to one sorting position, and the unlocking switch is configured to cause the second end of the rotating part of the locking assembly of the flip-type sorting cart to rotate around the connecting axis of the locking assembly to drive the first end of the rotating part to rotate around the connecting axis in a direction away from the limiting column of the locking assembly.

[0016] In some embodiments of the present application, the sorting system further includes a reset mechanism fixed to the body frame, the reset mechanism including a resistance portion arranged along the direction from the sorting position to the loading position for resisting the pallet of the flip-type sorting trolley to reset the pallet, and the height of the resistance portion from the body frame gradually increases along the direction from the sorting position to the loading position; wherein, the lowest point of the resistance portion is defined as: when the first part of the tray support of the flip-type sorting trolley is rotated to a maximum angle in a direction close to the base assembly, the lowest point resists the pallet; the highest point of the resistance portion is defined as: when the first part of the tray support is restored to a state where the locking block installed on the second part of the tray support is locked with the lock of the locking assembly, the highest point resists the pallet.

[0017] In some embodiments of the present application, the conveying mechanism also includes two sprocket brackets and two sprockets respectively fixed on the two sprocket brackets, wherein the two sprocket brackets are respectively installed at the two ends of the body frame in a manner that they can move relative to the body frame, and the circulating conveying chain is tensioned on the outer surfaces of the two sprockets.

[0018] In some embodiments of the present application, the conveying mechanism also includes a track fixed on the two sprocket brackets, and the track is arranged along the circulating conveyor chain; the base assembly also includes a first roller confined inside the track and / or two second rollers respectively in contact with the two outer walls of the track.

[0039] like Figures 1 to 8 As shown, an embodiment of the first aspect of the present application provides a flip-plate sorting trolley 100, comprising: a base assembly 10, a tray assembly 20, and a locking assembly. The tray assembly 20 comprises a tray 21 and a tray support 22. The first portion of the tray support 22 is used to support the tray 21. The first end of the second portion of the tray support 22 supports the first portion of the tray support 22 and is connected to the base assembly 10 via a first hinge 101, so that the first portion of the tray support 22 can rotate around the axis of the first hinge 101 in a direction close to the base assembly 10. The locking assembly comprises a connecting shaft 31, a rotating member 32, a torsion spring 33, a limiting column 34, and a locking block 35 installed at the second end of the second portion of the tray support 22. , and a lock buckle 36 adapted to the locking block 35; the connecting shaft 31 is fixed to the base assembly 10; the rotating member 32 is rotatably mounted on the connecting shaft 31; one end of the torsion spring 33 is fixed to the base assembly 10 or the connecting shaft 31, and the other end of the torsion spring 33 is fixed to the rotating member 32; the lock buckle 36 is arranged at a first end of the rotating member 32; the limiting column 34 is fixed to the base assembly 10 and is located between the locking block 35 and the connecting shaft 31, and the limiting column 34 is used to interfere with the first end of the rotating member 32 to keep the lock buckle 36 in a position to be locked with the locking block 35.

[0040] For example, if Figure 1 As shown, the second part of the tray bracket 22 is "L"-shaped, and the first end of the second part of the tray bracket 22 has a support plate 220 arranged perpendicular to the first part of the tray bracket 22. In this way, the support plate 220 is rotatably connected to the base assembly 10, so that the height difference between the first part of the tray bracket 22 and the base assembly 10 can be increased, so that the first part of the tray bracket 22 has a certain movable space relative to the base assembly 10, thereby making it easier for the first part of the tray bracket 22 to rotate around the axial direction of the first hinge close to the base assembly 10.

[0041] According to the embodiment of the first aspect of the present application, the flip-plate sorting trolley 100 provided by the embodiment of the first aspect of the present application has a first part of the tray bracket 22 supporting the tray 21, a first end of the second part of the tray bracket 22 supports the first part of the tray bracket 22 and is connected to the base assembly 10 through a first hinge 101, a second end of the second part of the tray bracket 22 is installed with a locking block 35 of the locking assembly, a connecting shaft 31 of the locking assembly is provided on the base assembly 10, a rotating member 32 with a lock buckle 36 connected at one end is rotatably sleeved on the connecting shaft 31, and the rotating member 32 is connected to the base assembly 10 or the connecting shaft 31. The torsion spring 33 is connected between the connecting shafts 31, and the base assembly 10 is further provided with a limiting post 34 that can interfere with the first end of the rotating member 32 to keep the lock buckle 36 in a position to achieve locking with the locking block 35. In this way, by toggling the second end of the rotating member 32, the first end of the rotating member 32 can be rotated in a direction away from the limiting post 34, thereby driving the lock buckle 36 to separate from the locking block 35. At this time, the locking assembly is in an unlocked state. Since the first part of the tray bracket 22 supports the tray 21, the tray 21 can also accommodate materials. Compared with the second part of the tray bracket 22, the tray 21 can also accommodate materials. The weight of the first part of the tray holder 22 is greater, so when the locking assembly is in the unlocked state, the locking block 35 provided at the second end of the second part of the tray holder 22 is no longer restricted by the lock buckle 36, so that the first part of the tray holder 22 can tilt toward the base assembly 10 under the action of its own gravity, thereby pouring out the materials on the tray 21; at the same time, when the external force acting on the second end of the rotating member 32 disappears, the rotating member 32 will automatically rotate under the elastic action of the torsion spring 33 to restore the deformation, and the rotating member is blocked by the limit column 34. The first end of the rotating member 32 remains in a position that interferes with the limiting post 34. Even if the lock catch 36 provided on the first end of the rotating member 32 is reset to a position where it can be locked with the lock catch 35, rotating the first portion of the tray support 22 will cause the lock block 35 provided on the second portion of the tray support 22 to be reset, and the lock block 35 and the lock catch 36 can be locked again. When the locking assembly is in the locked state, the lock block 35 provided on the second end of the second portion of the tray support 22 is restricted by the lock catch 36, so that the tray support 22 is fixed and the tray assembly 20 remains horizontally balanced. It can be seen that the tilting and resetting of the tray assembly 20 by the tilting and resetting of the tray assembly 20 by the tilting and resetting of the tray assembly 20 does not require electrical control, and thus does not require a complex wiring structure. Compared with sorting carts that install electromagnets on the tray and electrically control the electromagnets to tilt the tray, the tilting and resetting of the tray assembly 20 by ...

[0042] In some embodiments of the present application, Figure 1 and Figure 5As shown, the base assembly 10 includes a fixed base 11 and a limiting plate 12. One end of the limiting plate 12 is fixed to the fixed base 11, and the other end of the limiting plate 12 is used to limit the maximum rotation angle of the first portion of the tray support 22 about the axis of the first hinge 101, toward the base assembly 10. This maximum angle can be determined based on the desired tray tilt angle in actual application. For example, if the materials on the tray 21 need to be completely emptied when the tray 21 is tilted 45° from the horizontal position, the first portion of the tray support 22 can be configured to rotate 45° about the axis of the first hinge 101, toward the base assembly 10, before being blocked by the other end of the limiting plate 12. In other words, the maximum rotation angle of the first portion of the tray support 22 is limited to 45°. By providing the limiting plate 12 to limit the rotation of the first portion of the tray support 22 about the axis of the first hinge 101, toward the base assembly 10, the tray support 22 can be fixed at a preferred tilt angle, thereby facilitating the emptying of the materials in the tray 21 to a designated sorting location.

[0043] Furthermore, if Figure 1 and Figure 5 As shown, the other end of the limiting plate 12 has an inclined surface 121 adapted to the first part of the tray support 22 when it is rotated to the maximum angle. The inclined surface 121 can also be understood as being formed by the horizontal position of the limiting plate 12 tilted in the direction away from the tray assembly 20 at the maximum angle. In this way, after the first part of the tray support 22 is rotated to the maximum angle around the axial direction of the first hinge 101 in the direction close to the base assembly 10, the tray support 22 can be better supported by the other end of the limiting plate 12 through the cooperation of the inclined surface 121 and the side of the first part of the tray support 22 close to the base assembly 10, so that the tray support 22 can be better supported by the other end of the limiting plate 12, that is, the tray assembly 20 as a whole is more stable, which helps to more accurately and smoothly pour the materials in the tray 21 to the designated sorting position.

[0044] In some embodiments of the present application, Figure 2 、 Figure 5 、 Figure 7 and Figure 8 As shown, the locking block 35 is mounted on a side of the second portion of the tray support 22 close to the base assembly 10. One side of the locking block 35 has an opening, and the end of the locking buckle 36 is engaged in the opening to achieve locking with the locking block 35. Figure 2 and Figure 5When the cam 36 is in the unlocked position, the locking member 32 is unlocked and the locking member 32 is unlocked. It can be seen that by applying the locking assembly provided in the embodiment of the present application, the operation is simpler in the process of locking the locking block 35 and the locking buckle 36.

[0045] Furthermore, if Figure 1 and Figure 5 As shown, the limit plate 12 also has a spine 122 extending along the height direction of the base assembly 10 toward the direction close to the tray assembly 20, and the first end of the second part of the tray bracket 22 is rotatably connected to the spine 122 through a first hinge, which can increase the height difference between the tray bracket 22 as a whole and the base assembly 10, so that both sides of the tray bracket 22 have a certain gap relative to the base assembly 10. In this way, on the one hand, the first part of the tray bracket 22 has a certain gap relative to the base assembly 10, which can make it easier for the first part of the tray bracket 22 to rotate around the axial direction of the first hinge in the direction close to the base assembly 10; on the other hand, the second part of the tray bracket 22 has a certain gap relative to the base assembly 10, that is, it gives a certain matching space to the locking block 35 and the lock buckle 36, which makes it easier for the locking block 35 and the lock buckle 36 to be locked.

[0046] like Figures 1 to 12 As shown, an embodiment of the second aspect of the present application provides a sorting system, comprising at least one flip-plate sorting trolley 100 provided according to the embodiment of the first aspect of the present application.

[0047] According to the sorting system provided by the embodiment of the second aspect of the present application, the first part of the tray support 22 of the flip-type sorting trolley 100 supports the tray 21, the first end of the second part of the tray support 22 supports the first part of the tray support 22 and is connected to the base assembly 10 through the first hinge 101, the second end of the second part of the tray support 22 is installed with a locking block 35 of the locking assembly, the base assembly 10 is provided with a connecting shaft 31 of the locking assembly, and a rotating member 32 with a lock buckle 36 connected to one end is rotatably sleeved on the connecting shaft 31, and the rotating member 32 is connected to the base assembly 10 or a connecting shaft 31 is connected with a torsion spring 33, and the base assembly 10 is also provided with a limiting post 34 that can interfere with the first end of the rotating member 32 to keep the lock 36 in a position to achieve locking with the locking block 35. In this way, by toggling the second end of the rotating member 32, the first end of the rotating member 32 can be rotated in a direction away from the limiting post 34, thereby driving the lock 36 to separate from the locking block 35. At this time, the locking assembly is in an unlocked state. Since the first part of the tray bracket 22 supports the tray 21, the tray 21 can also accommodate materials. Compared with the second part of the tray bracket 22, , the weight of the first part of the tray support 22 is greater, so when the locking assembly is in the unlocked state, the locking block 35 provided at the second end of the second part of the tray support 22 is no longer restricted by the lock buckle 36, so that the first part of the tray support 22 can be tilted toward the direction close to the base assembly 10 under the action of its own gravity, thereby pouring out the materials on the tray 21; at the same time, when the external force acting on the second end of the rotating member 32 disappears, the rotating member 32 will automatically rotate under the elastic action of the torsion spring 33 to restore the deformation, and the rotation is blocked by the limit column 34. The first end of the member 32 remains in contact with the limiting post 34. Even if the lock catch 36 provided on the first end of the rotating member 32 is reset to a position where it can be locked with the lock catch 35, the first portion of the tray support 22 is rotated to reset the lock block 35 provided on the second portion of the tray support 22, allowing the lock block 35 to be locked with the lock catch 36 again. When the locking assembly is in the locked state, the lock block 35 provided on the second end of the second portion of the tray support 22 is restrained by the lock catch 36, thereby securing the tray support 22 and maintaining the tray assembly 20 in a horizontal balance. It can be seen that in the sorting system provided by the embodiment of the present application, the tilting-plate sorting trolley 100 does not rely on electrical control to achieve the tilting and resetting of the tray assembly 20, thereby eliminating the need for a complex wiring structure. Compared to sorting trolleys that use electromagnets installed on the tray and electrically controlled to tilt the tray, the sorting system provided by the embodiment of the present application has a lower failure rate, resulting in higher overall reliability of the sorting system.

[0048] In some embodiments of the present application, Figure 9 and Figure 11As shown, the sorting system also includes a frame 200 and a conveying mechanism mounted on the frame 200. The conveying mechanism includes a circulating conveyor chain 301 arranged along at least one loading position and at least one sorting position. The base assembly 10 of the flip-plate sorting trolley 100 is connected to the circulating conveyor chain 301 via bolts. Thus, the movement of the circulating conveyor chain 301 drives the flip-plate sorting trolley 100 to move along a predetermined path to each loading position or sorting position.

[0049] In some embodiments of the present application, Figure 10 and Figure 12 As shown, the sorting system further includes an unlocking switch 400 arranged on the body frame 200 opposite to each sorting position. One unlocking switch 400 corresponds to one sorting position. The unlocking switch 400 is configured to cause the second end of the rotating member 32 of the locking assembly of the flip-type sorting trolley 100 to rotate around the connecting shaft 31 of the locking assembly 20, so as to drive the first end of the rotating member 32 to rotate around the connecting shaft 31 in a direction away from the limiting column 34 of the locking assembly. For example, the unlocking switch 400 may include a telescopic rod and a cylinder for controlling the extension and retraction of the telescopic rod. When the flip-plate sorting trolley 100 carrying materials to be sorted to the first sorting position moves toward the first sorting position, the cylinder of the unlocking switch 400 can control its telescopic rod to move along the axial direction of the connecting shaft 31 toward the direction close to the rotating part 32, so that when the flip-plate sorting trolley 100 reaches the first sorting position, the second end of the rotating part 32 can just be resisted by the telescopic rod and rotate around the connecting shaft 31, thereby driving the first end of the rotating part 32 to separate from the limit column 34. Then, the locking block 35 provided at the second end of the second part of the tray bracket 22 is no longer restricted by the lock buckle 36, so that the first part of the tray bracket 22 can tilt toward the base assembly 10 under the action of its own gravity, and then pour out the materials on the tray 21 at the first sorting position. It can be seen that by correspondingly providing an unlocking switch 400 at each sorting position, which enables the second end of the rotating member 32 to rotate around the connecting shaft 31 to drive the first end of the rotating member 32 to rotate in a direction away from the limiting column 34 of the locking assembly, it is easier to control each flip-type sorting trolley 100 to pour out the materials on its own tray 21 at the designated sorting position.

[0050] In some embodiments of the present application, Figure 10 and Figure 12As shown, the sorting system also includes a reset mechanism 500 fixed on the body frame 200, and the reset mechanism 500 includes a resistance part 401 arranged along the direction from the sorting position to the loading position, for resisting the tray 21 of the flip-plate sorting trolley 100 to reset the tray 21, and along the direction from the sorting position to the loading position, the height of the resistance part 401 from the body frame 200 gradually increases; wherein, the lowest point of the resistance part 401 is defined as: when the first part of the tray support 22 of the flip-plate sorting trolley 100 is rotated to the maximum angle in the direction close to the base assembly 10, the lowest point is in contact with the tray 21; the highest point of the resistance part 401 is defined as: when the first part of the tray support 22 is restored to a state where the locking block 35 installed on the second part of the tray support 22 is locked with the lock buckle 36 of the locking assembly, the highest point is in contact with the tray 21. After the flip-plate sorting trolley 100 is in the sorting position and its locking assembly is in the unlocked state, that is, the first part of the tray bracket 22 of the flip-plate sorting trolley 100 rotates to the maximum angle in the direction close to the base assembly 10, at this time, the flip-plate sorting trolley 100 continues to move to the loading position under the drive of the circulating conveyor chain 301. By setting the reset mechanism 500, during the movement of the flip-plate sorting trolley 100 from the sorting position to the loading position, the tray 21 of the flip-plate sorting trolley 100 is first connected to the loading position. The tray 21 contacts the lowest point of the interference portion 401, and then the tray 21 is gradually lifted up along the interference portion 401 in a direction away from the base assembly 10. At the same time, the second end of the second portion of the tray support 22 gradually rotates in a direction close to the base assembly 10 until the locking block 35 and the lock catch 36 are locked, that is, until the tray 21 reaches the highest point of the interference portion 401 and contacts the highest point. In this way, the tray assembly 20 is restored to a horizontal equilibrium state, making it convenient to load new materials when it passes the loading position next time. It can be seen that by providing the reset mechanism 500, the tray assembly 20 can be automatically reset when the locking assembly is in the unlocked state so that the locking assembly can be locked again, thereby improving the automation level of the sorting system and the convenience of use.

[0051] In some embodiments of the present application, Figure 9 and Figure 11As shown, the conveying mechanism further includes two sprocket brackets 302 and two sprockets 303 respectively fixed to the two sprocket brackets 302, wherein the two sprocket brackets 302 are respectively mounted on the two ends of the body frame 200 in a manner that is movable relative to the body frame 200, and the endless conveying chain 301 is tensioned on the outer surfaces of the two sprockets 303. By providing two sprocket brackets 302 respectively mounted on the two end sprocket brackets 302 of the body frame 200 in a manner that is movable relative to the body frame 200, and fixing a sprocket 303 on each of the two sprocket brackets 302, the center distance between the two sprocket brackets 302 can be adjusted to more conveniently complete the assembly and disassembly of the endless conveying chain 301 and the sprocket 303, and it is also more convenient to adjust the tension between the endless conveying chain 301 and the sprocket 303, thereby improving the transmission reliability between the conveying chain 301 and the sprocket 303.

[0052] In some embodiments of the present application, Figures 9 to 12 As shown, the conveying mechanism also includes a motor drive assembly 800, which is mounted on the sprocket bracket 302 and is used to drive the rotation of either sprocket 303. Because the endless conveyor chain 301 is tensioned on the outer surfaces of the two sprockets 303, when the motor drive assembly 800 drives either sprocket 303 to rotate, the other sprocket 303 will also rotate under the transmission action of the endless conveyor chain 301, thereby driving the flip-type sorting cart 100 to move in a circular motion.

[0053] In some embodiments of the present application, Figure 9 and Figure 11 As shown, the conveying mechanism further includes a track 304 fixed to two sprocket brackets 302, and the track 304 is arranged along the endless conveyor chain 301; the base assembly 10 further includes a first roller 131 confined within the track 304 and / or two second rollers 132 respectively contacting two outer side walls of the track 304. By arranging the track 304 along the endless conveyor chain 301, and arranging the first roller 131 confined within the track 304 and / or two second rollers 132 respectively contacting two outer side walls of the track 304 on the base assembly 10 of the flip-plate sorting trolley 100, the base assembly 10 of the flip-plate sorting trolley 100 can better maintain horizontal balance while being driven by the endless conveyor chain 301 and can more stably travel along a fixed logistics conveying path.

[0054] In some embodiments of the present application, reference is made to Figure 9 and Figure 12As shown, the sorting system further includes a hydraulic buffer 600 and a chute 700 provided at each sorting position. The first end of the chute 700 is connected to the machine frame 200 via a second hinge, and the second end of the chute 700 is supported by the hydraulic buffer 600. By providing the hydraulic buffer 600 to support the second end of the chute 700 and connecting the first end of the chute 700 to the machine frame 200 via the second hinge, the chute 700 can rotate relative to the machine frame 200 around the axis of the second hinge under the action of an external force. This increases the angular adjustability of the chute 700 and facilitates improved discharge efficiency at each sorting position.

[0055] In some embodiments of the present application, a cover plate 14 is installed between the base assemblies 10 of each pair of flip-plate sorting carts 100. For example, each cover plate 14 can be made of plastic, rubber, or silicone. The installation of the cover plate 14 between the base assemblies 10 of each pair of flip-plate sorting carts 100 not only protects the cleanliness of the endless conveyor chain 301 and / or the track 304 during the loading and sorting process but also improves the safety of the sorting system.
