[0044] It should be noted that the directional nouns such as "up", "down", "front", "back", "left", and "right" mentioned in this article are Figure 1 、 Figure 3 and Figure 6 The orientation is used as a reference, and the left and right directions are also the axial directions of the drive shaft.

[0045] Example 1

[0046] The linear sorting machine comprises a frame 1, a drive assembly mounted on the frame 1, and a circular conveyor assembly 4 mounted on the frame 1 and formed by a plurality of carts 2 connected end-to-end. The axis of the circular conveyor assembly 4 is parallel to the horizontal plane, and the drive assembly drives the circular conveyor assembly 4 along the circular path formed by the plurality of carts 2. Each cart 2 has a narrow circular belt 21 for placing goods, and the axis of the narrow circular belt 21 is arranged perpendicular to the axis of the circular conveyor assembly 4. When the drive assembly drives the circular conveyor assembly 4, when one or more carts 2 move to the target sorting position, the carts 2 start to move the narrow circular belt 21 along the circular path formed by the plurality of carts 2, and the goods carried by the narrow circular belt 21 are sorted to the left or right side of the circular conveyor assembly 4.

[0047] On this basis, if Figures 1 to 5 As shown, this embodiment provides a trolley 2 of a linear sorting machine, which includes a frame 22, a narrow belt connector, at least two annular narrow belts 21 installed on the frame 22, and at least two narrow belt units rotatably installed on the frame 22 and arranged in sequence from front to back; the narrow belt unit is used to drive its corresponding annular narrow belt to rotate; the narrow belt connector is used to connect adjacent annular narrow belts, and the connected annular narrow belts are synchronously linked.

[0048] The trolley of the linear sorting machine set up in this way connects adjacent narrow belts through narrow belt connectors to achieve adjustable narrow belt width, and then drives the narrow belt with adjusted width according to a narrow belt unit corresponding to the narrow belt with adjusted width, so that users can select the appropriate narrow belt width according to the specifications of the goods to be sorted.

[0049] Preferably, the annular narrow belt is driven by a roller; the narrow belt unit includes a transmission shaft, a clutch, a driving wheel and an active transmission wheel; the transmission shaft is mounted on the frame 22, the driving wheel is fixedly sleeved on the transmission shaft 23, the active transmission wheel 28 is rotatably sleeved on the transmission shaft 23, the clutch 27 has a fixed seat 291 fixedly connected to the frame 22 and a rotating seat 292 fixedly sleeved on the transmission shaft 23; the driving wheel is used to be placed on the frame of the linear sorter and continuously roll along the frame as the trolley moves on the sorting path, and the active transmission wheel 28 is transmission-connected to the roller; when the clutch 27 is energized, the rotating seat 292 attracts the active transmission wheel 28, forming a transmission connection between the driving wheel and the active transmission wheel 28, and the active transmission wheel 28 and the roller still maintain a transmission connection.

[0050] The sorting path refers to the moving path of the cart used to sort the goods. As an example, Figure 6As shown, the moving path of the trolley is a ring, including a first path segment, a second path segment, a third path segment and a fourth path segment connected in sequence from head to tail. The first path segment and the second path segment are straight paths arranged relatively along the up and down directions, and the first path segment is located above the second path segment. The third path segment and the fourth path segment are curved paths arranged relatively along the left and right directions; among them, the first path segment is the sorting path.

[0051] The operating principle of the aforementioned trolley is as follows: when the sorter is activated, the drive assembly applies driving force to the trolley, prompting it to move along the circular path formed by the circular conveyor assembly. As the trolley moves along the sorting path, the drive assembly's driving force is transmitted to the drive wheels, causing them and the mounting shaft to continuously roll along the frame. When the narrow belt reaches the target sorting position, the clutch is energized, and the rotating seat engages the active drive wheel. The drive wheel drives the rotating seat and the active drive wheel, which in turn drives the rollers, rotating the circular narrow belt to sort the goods carried on the circular narrow belt to the left or right side of the linear sorter. This achieves the goods sorting function without the need for a motorized roller to drive the narrow belt.

[0052] The trolley arranged as above can, through the driving wheel, draw power from the main drive of the linear sorter (i.e., the drive component used to drive the movement of the circular conveyor component) to the trolley, thereby driving the circular narrow belt on the trolley to move, so as to sort the goods carried on the circular narrow belt to the left or right side of the linear narrow belt sorter. Due to the high power of the main drive, the torque output from the main drive to the trolley chain is relatively large, so that the narrow belt can transport heavier goods.

[0053] The transmission shaft 23 is mounted on the vehicle frame 22 in a vertical direction, or the transmission shaft 23 is mounted on the vehicle frame 22 in a horizontal direction. Specifically, in this embodiment, the transmission shaft 23 is mounted on the vehicle frame 22 in a horizontal direction.

[0054] Preferably, the narrow belt unit further includes a driven transmission wheel 26 whose rotation axis is consistent with the rotation axis of the annular narrow belt 7. The driven transmission wheel 26 is rotatably mounted on the frame 22. The active transmission wheel 28 is transmission-connected to the driven transmission wheel 26, and the driven transmission wheel 26 is transmission-connected to the roller.

[0055] Preferably, in this embodiment, both the active transmission wheel and the passive transmission wheel are bevel gears, meshing with each other. This simplifies the structure and stabilizes the transmission between the active and passive transmission wheels. Furthermore, the active transmission wheel has a toothed portion and a toothless portion connected in sequence, with the toothed portion being located away from the rotating base 292 and the toothless portion being located closer to the rotating base 292.

[0056] Optionally, both the active transmission wheel and the driven transmission wheel are conical friction wheels ("conical friction wheel" refers to a transmission wheel with a conical gear surface of a bevel gear replaced by a conical friction surface), and the conical friction surface of the active transmission wheel is transmission-connected to the conical friction surface of the driven transmission wheel.

[0057] Preferably, a clutch 27, a driving drive wheel 28, and a driven drive wheel 26 cooperate to form a transmission unit. Two transmission units, arranged from left to right, can be mounted on the transmission shaft 23 to connect to the rollers. The first transmission unit drives the endless narrow belt 21 in a first direction, while the second transmission unit drives the endless narrow belt 21 in a second direction. Thus, through the two transmission units, a narrow belt can sort goods in two directions (i.e., left and right), making the trolley 2 more flexible in sorting.

[0058] Preferably, the trolley 2 further includes a first roller 29 and a second roller 30 arranged sequentially from left to right, and an annular narrow belt 21 sleeved on the first roller 29 and the second roller 30, and a driven transmission wheel 26 is drivingly connected to the first roller 29. The structure is simple and compact, and the driven transmission wheel 26 drives the annular narrow belt 21.

[0059] Preferably, the end of the driven transmission wheel 26 away from the active transmission wheel 28 has a first sprocket 261, and the first sprocket 261 is coaxially arranged with the driven transmission wheel 26. The end of the first roller 29 has a second sprocket 321, and the second sprocket 321 is coaxially arranged with the first roller 29. The first sprocket 261 and the second sprocket 321 are chain-drivenly connected.

[0060] Optionally, the first sprocket 261 is replaced by a first belt pulley, and the second sprocket 321 is replaced by a second belt pulley, and the first belt pulley is connected to the second belt pulley by belt transmission.

[0061] Optionally, the first sprocket 261 is replaced by a first gear, and the second sprocket 321 is replaced by a second gear, and the first gear and the second gear are connected through a gear set.

[0062] Optionally, the first sprocket 261 is replaced by a first bevel gear, and the second sprocket 321 is replaced by a second bevel gear. The first bevel gear and the second bevel gear are connected via a rotating shaft. The first end of the rotating shaft has a bevel gear meshing with the first bevel gear, and the second end of the rotating shaft has a bevel gear meshing with the second bevel gear.

[0063] Preferably, the frame 22 comprises a transmission case and a narrow belt frame 222, arranged sequentially from bottom to top. A transmission shaft 23 is disposed through the transmission case. The first end of the transmission shaft 23 extending from the transmission case is fixedly connected to a first drive wheel 24, while the second end of the transmission shaft 23 extending from the transmission case is fixedly connected to a second drive wheel 25. All transmission units are housed within the transmission case. The narrow belt frame 222 is mounted with a first roller 29, a second roller 30, and the endless narrow belt 21. This creates a compact structure, and the transmission case protects the clutch 27, active drive wheel 28, and driven drive wheel 26 within it.

[0064] Preferably, the endless narrow belt 21 has a contact surface that contacts the rollers. An annular guide strip is provided on the contact surface along the belt's path. The rollers (including the first roller 29 and the second roller 30) are provided with an annular guide groove that surrounds the rollers, and the annular guide strip is accommodated within the annular guide groove. This ensures that the annular narrow belt does not shift forward or backward during rotation driven by the rollers, maintaining stable sorting operations.

[0065] More preferably, the transmission case comprises two housings, arranged from left to right, namely a first housing 223 and a second housing 224. All first transmission units are housed in the first housing 223, and all second transmission units are housed in the second housing 224. This allows the middle portion of the transmission shaft 23 to be exposed between the first housing 223 and the second housing 224, making it easier to use the middle portion of the transmission shaft 23 for connecting adjacent trolleys 2. This results in a more compact structure and minimizes the gap between adjacent narrow belts.

[0066] Preferably, the first roller 29 is located on the left side of the first transmission unit, and the second roller 30 is located on the right side of the second transmission unit. The fifth sprocket 225 is rotatably mounted on the narrow belt frame 222 at a position corresponding to the first transmission unit, and the sixth sprocket 226 is rotatably mounted on the narrow belt frame 222 at a position corresponding to the second transmission unit. The first sprocket 261 is connected to the fifth sprocket 225 via a first chain, the fifth sprocket 225 is connected to the second sprocket 321 via a second chain, the third sprocket 271 is connected to the sixth sprocket 226 via a third chain, and the sixth sprocket 226 is connected to the fourth sprocket 331 via a fourth chain. This makes the structure more compact.

[0067] Preferably, the clutch 27 is an electromagnetic clutch or a magnetic powder clutch. Specifically, in this embodiment, the clutch 27 is an electromagnetic clutch. Optionally, the clutch 27 is a hydraulic clutch or a pneumatic clutch.

[0068] Preferably, the first drive wheel 24 and the second drive wheel 25 are gears, which are placed on the rack of the frame 1 to receive driving force and rotate along the frame 1 to drive the trolley 2 to move. In this way, by configuring the first drive wheel 24 and the second drive wheel 25 as gears and cooperating with the rack on the frame 1, it is possible to more effectively draw power from the main drive of the linear sorter and output it stably to the trolley 2.

[0069] Of course, configuring both the first and second drive wheels 24, 25 as gears is merely an optimization. It is conceivable that both the first and second drive wheels 24, 25 could be configured as friction wheels, placed on a friction belt on the frame 1 to receive the driving force and rotate along the frame 1 to drive the movement of the trolley 2. This would also effectively leverage the power of the linear sorter's main drive and stably output it to the trolley 2. Furthermore, both the friction wheel and the friction belt are made of rubber, with friction stripes on their surfaces, and friction stripes on their surfaces. This further increases the friction between the friction wheel and the friction belt, improving the effectiveness and stability of leveraging the power of the linear sorter's main drive.

[0070] Preferably, at least the first end and the second end of the transmission shaft 23 are threaded, the first drive wheel 24 is threadedly connected to the first end of the transmission shaft 23, and the second drive wheel 25 is threadedly connected to the second end of the transmission shaft 23. Two nuts are respectively used on either side of the first drive wheel 24 to lock and secure the first drive wheel 24 to the transmission shaft 23, and two nuts are respectively used on either side of the second drive wheel 25 to lock and secure the second drive wheel 25 to the transmission shaft 23. This secures the first drive wheel 24 and the second drive wheel 25 to the transmission shaft 23, making installation and removal easy. Alternatively, the first drive wheel 24 is welded to the first end of the transmission shaft 23, and the second drive wheel 25 is welded to the second end of the transmission shaft 23. This also secures the first drive wheel 24 and the second drive wheel 25 to the transmission shaft 23.

[0071] Preferably, a first guide wheel 31 is rotatably mounted on the first end of the transmission shaft 23, and a second guide wheel 32 is rotatably mounted on the second end of the transmission shaft 23. The first guide wheel 31, the second guide wheel 32, and the transmission shaft 23 are coaxially arranged. The first guide wheel 31 is located on the side of the first drive wheel 24 away from the second drive wheel 25, and the second guide wheel 32 is located on the side of the second drive wheel 25 away from the first drive wheel 24. In this way, the first guide wheel 31 and the second guide wheel 32 can guide the trolley 2 to move along a predetermined path.

[0072] Example 2

[0073] This embodiment provides a method for using the linear sorting machine trolley 2 in Example 1, including the following steps:

[0074] According to the specifications of the goods to be sorted, adjacent narrow bands are connected using narrow band connectors to obtain a widened narrow band, and a narrow band unit is selected from the narrow band units corresponding to the widened narrow band to drive the expanded narrow band.

[0075] Example 3

[0076] This embodiment provides a linear sorting machine, such as Figure 6 and Figure 7 As shown. Figure 8 The figure shows a schematic diagram of a linear sorting machine that connects two narrow loops using narrow loop connectors. The linear sorting machine comprises a frame 1, a drive assembly mounted on the frame 1, and a circular conveyor assembly 4 mounted on the frame 1. The axis of the circular conveyor assembly 4 is parallel to the horizontal plane, and the drive assembly drives the circular conveyor assembly 4 along the circular path formed by the drive assembly. The circular conveyor assembly 4 is formed by a plurality of trolleys 2 as described in Example 1, connected end to end.

[0077] Preferably, the annular conveying assembly 4 further comprises a connecting plate, wherein, in the adjacent first trolleys 2 and second trolleys 2 arranged in sequence from front to back, a first mounting position is installed in the middle of the rearmost transmission shaft 23 of the first trolley 2, and a second mounting position is installed in the middle of the frontmost transmission shaft 23 of the second trolley 2. The first end of the connecting plate is mounted on the first mounting position and forms a rotational connection with the rearmost transmission shaft 23 of the first trolley 2, and the second end of the connecting plate is mounted on the second mounting position and forms a rotational connection with the frontmost transmission shaft 23 of the second trolley 2. Since the middle portion of the transmission shaft 23 is exposed between the first box body 223 and the second box body 224, the adjacent trolleys 2 are connected to form an annular conveying assembly 4 through the middle portion of the transmission shaft 23 and the connecting plate, so that the annular conveying assembly 4 is more compact in structure, the gap between adjacent narrow belts can be controlled to be smaller, and it is conducive to forming an annular conveying assembly 4 with a larger curvature (the greater the curvature of the annular conveying assembly 4, the smaller the space occupied, and the fewer trolleys 2 required for the same sorting length).

[0078] Specifically, in this embodiment, the first mounting position is rotatably mounted on the rearmost transmission shaft 23 of the first trolley 2, and the second mounting position is rotatably mounted on the frontmost transmission shaft 23 of the second trolley 2. The first end of the connecting plate is fixedly connected to the first mounting position, and the second end of the connecting plate is fixedly connected to the second mounting position. This facilitates installation.

[0079] Furthermore, the two plate surfaces of the connecting plate are respectively arranged toward the inner and outer sides of the annular conveying assembly 4. In this way, the connection between the adjacent trolleys 2 by the connecting plate is more stable.

[0080] Preferably, the left side of the frame 1 corresponds to the annular conveying assembly 4 and is provided with a first annular groove with a notch facing right, and the right side of the frame 1 corresponds to the annular conveying assembly 4 and is provided with a second annular groove with a notch facing left; all the first guide wheels 31 of the annular conveying assembly 4 are located in the first annular groove, and the two groove walls arranged opposite to each other in the first annular groove limit the first guide wheel 31, and all the second guide wheels 32 of the annular conveying assembly 4 are located in the second annular groove, and the two groove walls arranged opposite to each other in the second annular groove limit the second guide wheel 32; a third guide wheel (not shown in the figure) is provided at the bottom of the transmission box of the trolley 2, and the axis of the third guide wheel is perpendicular to the conveying surface of the annular narrow belt 21, and the frame 1 corresponds to the annular conveying assembly 4 and is provided with a third annular groove with a notch facing the outside of the annular conveying assembly 4, and all the third guide wheels of the annular conveying assembly 4 are located in the third annular groove, and the two groove walls arranged opposite to each other in the third annular groove limit the third guide wheel. In this way, by cooperating with the first guide wheel 31 and the first annular groove, and the second guide wheel 32 and the second annular groove, the frame 1 can limit the annular conveying assembly 4 in the up and down directions and the front and back directions. By cooperating with the third guide wheel and the third annular groove, the frame 1 can limit the annular conveying assembly 4 in the left and right directions, so that the annular conveying assembly 4 can move stably along the annular path formed by it.

[0081] Preferably, the left side of the frame 1 is provided with a first annular rack corresponding to the annular conveying assembly 4, and the right side of the frame 1 is provided with a second annular rack 11 corresponding to the annular conveying assembly 4; the first driving wheel 24 is a gear, and the first driving wheel 24 is placed on the first annular rack, and the second driving wheel 25 is a gear, and the second driving wheel 25 is placed on the second annular rack 11.

[0082] It should be noted that the drive assembly mounted on the frame 1 can be a linear motor or a rotary motor, and the present invention is not limited thereto. Specifically, in this embodiment, the drive assembly is a linear motor and includes a primary structure and a secondary structure. The primary structure is mounted on the frame 1 and located in the middle of the annular conveyor assembly 4 in the vertical direction, and the secondary structure is mounted on the plate surface of the connecting plate facing the inner side of the annular conveyor assembly 4.
