Description

Technical Field

[0001] The present invention relates to a sorting working method and equipment for sorting using the sorting working method, in particular to a sorting working method of a sorting trolley and a cross-belt sorter, belonging to the technical field of cross-belt sorters. Background Art

[0002] A cross-belt sorter, also known as a cross-belt sorting system, is a highly automated logistics device widely used in express delivery, postal services, e-commerce warehousing, and other fields. It primarily consists of a main-drive belt conveyor and a sorting cart. The main-drive belt conveyor drives the sorting cart, which then places the merchandise to be sorted. When the sorting cart reaches the designated sorting position, the belt on the cart rotates, completing the sorting process. Because the main-drive belt conveyor and the belt on the sorting cart intersect, it is called a cross-belt sorter.

[0003] In previous cross-belt sorting machines, it was necessary to drive the belt on the sorting trolley to rotate during sorting. The usual practice was to provide a belt drive device on the sorting trolley to drive the belt of the sorting trolley to rotate. However, providing the belt drive device on the sorting trolley would complicate the overall structure of the sorting trolley, resulting in higher manufacturing and maintenance costs. In addition, it would make the sorting trolley heavier, reducing the reliability and service life of the cross-belt sorter.

[0004] To this end, a Chinese invention patent application with application publication number CN110525869A and application publication date December 3, 2019 discloses a cross-sorting trolley device, which includes a sorting slide, a sorting trolley and a sorting port electromagnetic control device, wherein the sorting trolley is slidably mounted on the sorting slide; the sorting trolley includes a base plate, a roller, a roller and a driving gear, the roller is rotatably mounted on the base plate and the roller is in contact with the sorting slide, the number of the rollers is at least two, and the rollers are rotatably mounted on the top surface of the base plate, a conveyor belt is wound on the roller, and a driving rod is rotatably mounted on the base plate, and the upper end of the driving rod is engaged with the driven bevel gear on the top surface of the base plate through a driving bevel gear, and the driven bevel gear drives the conveyor belt to rotate, and the driving The driving gear is fixedly installed at the lower end of the rod, and the sorting port electromagnetic control device is installed at each sorting port. The sorting port electromagnetic control device includes a control box, a mounting plate and a drive box. The mounting plate is slidably installed on the top surface of the control box, and the drive box is installed on the top surface of the mounting plate and the drive box is at the same height as the driving gear; a sliding rod is provided inside the drive box, and the drive box has an opening on the side facing the driving gear, and a part of the sliding rod extends from the opening, and a rack plate that cooperates with the driving gear is installed on the side of the sliding rod facing the driving gear, the length of the opening on the drive box is greater than the length of the sliding rod, and the sliding rod is connected to the inner side surface of the drive box through a buffer spring on two opposite sides in the length direction.

[0005] In the aforementioned patent document, the conveyor belt of the sorting trolley is driven by the meshing of a rack plate in the sorting port electromagnetic control device located at the sorting port and a drive gear mounted on the sorting trolley. In this patent document, the sorting port electromagnetic control device with the rack plate, which is part of the mechanism that drives the conveyor belt, is separated from the sorting trolley and is not designed as an integrated structure with the sorting trolley. While this can reduce the overall weight of the sorting trolley to a certain extent, the transmission mechanism with the drive gear is still provided on the sorting trolley, which also makes the overall structure of the sorting trolley more complex, thereby increasing manufacturing and maintenance costs. Furthermore, the sorting trolley is still relatively heavy, reducing the reliability and service life of the cross-belt sorter and increasing energy consumption and other operating costs.

[0006] In summary, how to redesign a sorting method of a sorting trolley and a cross-belt sorter so that they can not only ensure the normal sorting work of the sorting trolley but also further simplify the overall structure of the sorting trolley and reduce manufacturing and maintenance costs; further realize the lightweighting of the sorting trolley, reduce the overall weight of the sorting trolley, improve the reliability and service life of the cross-belt sorter, and reduce energy consumption and other usage costs are technical problems that need to be solved urgently.

By providing an angled end at one end of the trolley belt and one end of the drive gear, the belt drive teeth can be smoothly inserted between the teeth of the drive gear to form a chimeric state. By further designing the redundant rotation amount of the drive gear, when one end of the trolley belt contacts one end of the drive gear, the axial force F applied by the insertion of the trolley belt allows the drive gear to flexibly rotate within the redundant rotation amount to a certain angle without driving the drive motor's shaft to rotate, thereby creating a misalignment with the one end of the trolley belt. This allows the belt drive teeth to smoothly insert between the teeth of the drive gear, forming a chiseled state. At the same time, when the drive motor's shaft rotates beyond the designed redundant rotation amount, it can still drive the drive gear to rotate normally, ensuring the normal progress of the sorting work. By also providing a belt conveyor at each sorting station, when the sorted goods are fragile, the trolley belt of the sorting trolley can first transport the goods to the belt conveyor, and then sort the goods from the belt conveyor. This prevents fragile goods from directly falling and being damaged during the conveying process of the sorting trolley belt, ensuring the integrity of the sorted goods. When sorting, the same drive gear can drive the transmission belt and the trolley belt to rotate at the same time, further simplifying the structure of the cross-belt sorter and reducing manufacturing and maintenance costs.

[0024] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The present application discloses a sorting working method for a sorting trolley, in which the outer surface of the trolley belt of the sorting trolley is set to a toothed structure, and a driving gear mechanism is set at a sorting location; the sorting working method is as follows: when the sorting trolley moves along a track to a sorting location, when sorting is required at the sorting location, the driving gear of the driving gear mechanism is controlled to rotate, and the driving gear of the driving gear mechanism is matched with the toothed structure of the trolley belt of the sorting trolley, thereby driving the trolley belt of the sorting trolley to rotate, and starting the sorting work.

[0026] The driving gear mechanism can be designed as a fixed driving gear mechanism and a movable driving gear mechanism. The fixed driving gear mechanism is described below through Examples 1 and 2, and the movable driving gear mechanism is described through Examples 3 to 9. Example 1: Figure 1 and Figure 2 As shown, a cross-belt sorting machine includes a conveyor 1 and a plurality of sorting carts 2 arranged on the track 111 of the conveyor 1. The plurality of sorting carts 2 are slidably connected to the track 111 of the conveyor 1 and driven by the conveyor 1 to drive the plurality of sorting carts 2 to move along the track of the conveyor 1. In this embodiment, the track is a horizontal annular track, that is, the track is arranged in a ring shape on the horizontal plane. Here, the track can also be arranged as a vertical annular track, that is, the track is arranged in a ring shape on the vertical plane. The conveyor 1 can adopt a main drive belt conveyor, which adopts a conveyor belt 112 to drive the sorting cart 2 to move along the track 111. On the path where the sorting cart 2 moves along the straight section of the track, a plurality of sorting locations are provided, such as Figure 1 Six sorting stations are provided, namely A1 to A6. A fixed drive gear mechanism 3 is provided at each sorting station. In this embodiment, the fixed drive gear mechanism 3 is provided on the side of the track 111. Here, the fixed drive gear mechanism 3 can also be provided on other components other than the track 111.

[0027] The sorting trolley 1 includes a body 211, a first roller 212 and a second roller 213 rotatably connected to the body 211. A trolley belt 214 is also coupled and driven between the first and second rollers 212 and 213. The trolley belt 214 is an endless belt with a toothed outer surface, i.e., a plurality of belt drive teeth 2141 are provided on the outer surface of the endless belt. The first roller 212 and the second roller 213 are respectively provided at the inner ends of the endless belt. The rotation of the trolley belt 214 can drive the rotation of the first roller 212 and the second roller 213. A pulley 215 is also provided at the bottom of the body 211. The multiple sorting trolleys 2 are slidably connected to the track 111 of the conveyor 1 via the pulleys 211 at the bottom of the trolley 211. The fixed driving gear mechanism 3 includes a driving device and a driving gear 311 arranged on the driving device. The driving device can drive the driving gear 311 to rotate. The tooth shape of the driving gear 311 matches the tooth shape of the tooth structure on the belt. The axial direction of the annular trolley belt 214 is parallel to the axial direction of the driving gear 311.

[0028] The sorting method of this embodiment is described by taking an A1 sorting station as an example. Figure 3 As shown, the sorting trolley 2 moves along the track 111 in a circular motion driven by the conveyor 1. At this time, the sorting trolley 2 has not yet reached the sorting position A1. The sorting trolley 2 moves along the straight section of the track 111 toward the sorting position A1. Figure 2 and Figure 4 As shown, when the sorting trolley 2 moves to the A1 sorting location, the driving gear 311 of the fixed driving gear mechanism 3 contacts one end of the trolley belt 214 of the sorting trolley 2, so that the belt transmission tooth 2141 of the trolley belt 214 of the sorting trolley 2 is inserted into the driving gear 311 along the axial direction (X direction) of the driving gear 311 of the fixed driving gear mechanism 3, so that the tooth structure of the trolley belt 214 is in a meshing state with the driving gear 311 of the fixed driving gear mechanism 3. At this time, when sorting is required at the A1 sorting location, the driving gear 311 of the fixed driving gear mechanism 3 is controlled to rotate, thereby driving the trolley belt 214 of the sorting trolley 2 to rotate, and the sorting work starts, as shown in FIG. Figure 5 As shown, the sorting trolley 2 continues to move, so that the driving gear 311 of the fixed driving gear mechanism 3 moves relatively to the other end of the trolley belt 214 of the sorting trolley 2, as shown in FIG. Figure 6As shown, under the continuous movement of the sorting trolley 2, the driving gear 311 of the fixed driving gear mechanism 3 is separated from the other end of the trolley belt 214 of the sorting trolley 2; when the tooth structure of the trolley belt 214 is in a meshing state with the driving gear 311 of the fixed driving gear mechanism 3 and there is no need to sort at the A1 sorting point, the fixed driving gear mechanism 3 is controlled to be in a shutdown state, and under the continuous movement of the sorting trolley 2, the tooth structure of the trolley belt 214 is relatively moved along the driving gear 311 of the fixed driving gear mechanism 3 until the driving gear 311 of the fixed driving gear mechanism 3 of the sorting trolley 2 is separated from the other end of the trolley belt 214 of the sorting trolley 2. Through the above design, the structure of the sorting trolley is greatly simplified while the sorting function of the sorting trolley is retained, so that when the sorting trolley needs to be sorted at the sorting location, it can perform sorting work normally, and when sorting is not required, it can continue to move smoothly along the track. Therefore, this embodiment ensures that the sorting trolley can perform normal sorting work while further simplifying the overall structure of the sorting trolley, reducing manufacturing costs and maintenance costs; further realizing the lightweighting of the sorting trolley, reducing the overall weight of the sorting trolley, improving the reliability and service life of the cross-belt sorter, and reducing energy consumption and other usage costs.

[0029] Here, it should be noted that when sorting is required at the sorting location, the sorting trolley can also be controlled to stop moving, and the driving gear of the fixed driving gear mechanism can be controlled to rotate, thereby driving the trolley belt of the sorting trolley to rotate and start sorting work. After the sorting work is completed, the sorting trolley continues to move, and as the sorting trolley continues to move, the driving gear of the fixed driving gear mechanism is separated from the trolley belt of the sorting trolley.

[0030] like Figure 7 As shown, when working, the belt transmission tooth 2141 at the end of the trolley belt 214 of the sorting trolley 2 is inserted into the driving gear 311 of the fixed driving gear mechanism 3 along the axial direction (X direction, as shown by the solid arrow in the figure) to form a chimeric structure. When just in contact, it is possible that the end face of the driving gear 311 and the end face of the belt transmission tooth 2141 will just come into contact. Therefore, in order to avoid the above two end faces colliding with each other and affecting the insertion of the belt transmission tooth 2141 into the teeth of the driving gear 311 to form a chimeric state, the applicant has made further design, such as Figure 8 and Figure 9As shown, the applicant sets one end of the trolley belt 214 to a belt bevel end 2142, and sets one end of the driving gear 311 to a gear bevel end 3111. In the process of the trolley belt 214 of the sorting trolley 2 moving toward the driving gear 311, the belt bevel end 2142 at one end of the trolley belt 214 is matched with the gear bevel end 3111 at one end of the driving gear 311 to contact each other, so that the belt drive tooth 2141 can be smoothly inserted into the teeth of the driving gear 311 to form a chimeric state. Here, it is also possible to simply set one end of the trolley belt 214 to the belt bevel end 2142 or set one end of the driving gear 311 to the gear bevel end 3111, but the best solution is to design both of them as bevel portions. On the basis of the above design, in order to further ensure that the belt drive tooth 2141 can be smoothly inserted into the teeth of the driving gear 311 to form a chimeric state, the applicant has also made further optimizations, namely: Figure 7 As shown, the drive gear 311 is designed to have a certain amount of redundant rotation relative to the drive device (as shown by the hollow arrow in the figure, the drive gear can rotate a certain angle relative to the rotating shaft of the drive device and then be limited to form an integral structure with the rotating shaft). In this way, when one end of the trolley belt 214 contacts one end of the drive gear 311, the drive gear 311 will be subjected to the axial force F of the insertion of the one end of the trolley belt 214, so that the drive gear 311 can flexibly rotate a certain angle within the redundant rotation without driving the rotating shaft 3121 of the drive motor to rotate together, thereby causing the teeth of the drive gear and the teeth of the belt drive teeth to be misaligned with each other, and ultimately allowing the belt drive teeth to be smoothly inserted into the teeth of the drive gear to form a chimeric state; at the same time, when the rotating shaft of the drive motor rotates beyond the designed redundant rotation, the drive gear is limited to form an integral structure with the rotating shaft, so that the drive motor can still drive the drive gear to rotate normally, ensuring the normal progress of the sorting work.

[0031] The redundant rotation structure can adopt the redundant rotation structure of some motors themselves, or can adopt a redundant rotation structure provided by the following applicants, such as Figures 10 to 12As shown, the drive device is a drive motor 312. The drive gear 311 is sleeved on the rotating shaft 3121 of the drive motor 312 via a bearing 4. The rotating shaft 3121 is provided with a rotating shaft flange 3122. A shift lever 5 is provided on the rotating shaft flange 3122. The axial direction of the shift lever 5 is parallel to the axial direction of the rotating shaft 3121. There are multiple shift levers 5, which are arranged sequentially along the circumference. The end surface of the drive gear 311 is provided with an arcuate groove 3112 that cooperates with the shift lever 5. There are also multiple arcuate grooves 3112, each positioned corresponding to the shift lever 5. When the drive gear 311 is sleeved on the rotating shaft 3121 of the drive motor 312 via the bearing 4, the shift lever 5 is inserted into the arcuate groove 3112, thereby forming a redundant rotation structure between the drive gear 311 and the rotating shaft 3121. Here, since the driving gear 311 is connected to the rotating shaft 3121 through the bearing 4, the driving gear 311 can rotate relative to the rotating shaft 3121. When the rotating shaft 3121 of the driving motor 312 rotates, it drives the shift lever 5 to move relatively along the arc groove 3112 from one end of the arc groove 3112 toward the other end thereof. During this process, since the shift lever 5 does not contact the arc groove 3112, the driving gear 311 does not rotate and has a certain amount of redundant rotation. When the shift lever 5 contacts the other end of the arc groove 3112, the driving gear is limited so that the driving gear and the rotating shaft form an integrated structure, and then the driving gear 311 is driven to rotate together with the rotating shaft 3121, thereby ensuring the normal progress of the sorting work. Before the belt drive tooth 2141 is inserted into the driving gear 311, the driving motor 312 is in a stopped state and the rotating shaft 3121 does not rotate. When one end of the trolley belt 214 is inserted into and contacts one end of the driving gear 311, the axial force F caused by the insertion of one end of the trolley belt 214 will cause the driving gear 311 to flexibly rotate a certain angle within the above-mentioned redundant rotation amount (that is, the shift rod 5 can move a certain distance along the arc groove 3112 without contacting the arc groove 3112), thereby avoiding one end of the trolley belt 214.

[0032] Example 2: Compared with Example 1, the difference is that the cross belt sorting machine of this embodiment further includes a belt conveyor arranged at each sorting location, such as Figure 13As shown, a belt conveyor 6 is installed at sorting stations A1 through A6. One end of the trolley belt 214 of the sorting trolley 2 moving to the sorting station is adjacent to one end of the transmission belt of the belt conveyor 6. This allows the sorted merchandise on the trolley belt 214 to be transferred to the transmission belt, and vice versa. When the sorted merchandise is fragile, the trolley belt 214 of the sorting trolley 2 first transports the merchandise to the belt conveyor 6 and then sorts the merchandise off the belt conveyor 6. This prevents fragile merchandise from falling and being damaged during transport on the trolley belt 214 of the sorting trolley 2, thus ensuring the integrity of the sorted merchandise.

[0033] like Figure 14 As shown, the basic structure of the belt conveyor 6 is the same as that of the sorting trolley, that is, it also includes a conveyor body 612, a roller 3 613 and a roller 4 614 rotatably connected to the conveyor body 612, and a transmission belt 611 is connected between the roller 3 613 and the roller 4 614 in a coordinated transmission manner. The transmission belt can be driven by providing a separate driving mechanism, such as providing a separate motor to drive the transmission belt 611 of the belt conveyor 6. However, in this embodiment, as shown in FIG. Figure 14 As shown, the transmission belt 611 and the trolley belt 214 are both driven by a drive gear 311. Specifically, the outer surface of the transmission belt 611 of the belt conveyor 6 is also configured with a toothed structure, and the tooth profile of the transmission belt 611 matches the tooth profile of the drive gear 311. The drive gear 311 of the fixed drive gear mechanism 3 meshes with the toothed structure of the transmission belt 611 for transmission connection. This design allows the transmission belt 611 and the trolley belt 214 to rotate simultaneously during sorting (as indicated by the arrows in the figure), further simplifying the structure of the cross-belt sorter and reducing manufacturing and maintenance costs.

[0034] Example 3: Compared with Example 1 and Example 2, the difference is that a movable drive gear mechanism is provided at each sorting location. In this embodiment, the movable drive gear mechanism is provided on the side of the track. Here, the movable drive gear mechanism can also be provided on other components other than the track.

[0035] like Figure 15As shown, in this embodiment, the movable drive gear mechanism 7 is an up-and-down lifting mechanism, which includes a lifting mechanism 711, a driving device 712 provided on the lifting mechanism 711, and a driving gear 311 provided on the driving device. The lifting mechanism 711 can drive the driving device 712 and the driving gear 311 to move up and down together, and the driving device can drive the driving gear 311 to rotate. In this embodiment, the lifting mechanism 711 can adopt a lifting cylinder, and the driving device can adopt a driving motor. The tooth profile of the driving gear 311 matches the tooth profile of the tooth structure on the belt. The axial direction of the endless trolley belt 214 is parallel to the axial direction of the driving gear 311.

[0036] The sorting method of this embodiment is described by taking an A1 sorting station as an example.

[0037] The sorting trolley 2 moves along the track 111 in a circular motion driven by the conveyor 1. At this time, the sorting trolley 2 has not yet reached the sorting location A1. The sorting trolley 2 moves toward the sorting location A1 along the straight section of the track 111. When the sorting trolley 2 moves to the sorting location A1, if sorting is required at the sorting location A1, Figure 16As shown, the lifting mechanism 711 of the movable driving gear mechanism 7 is controlled to move, driving the driving device 712 and the driving gear 311 to rise together, so that the driving gear 311 contacts one end of the trolley belt 214 of the sorting trolley 2, thereby inserting the driving gear 311 into the belt transmission tooth 2141 below the end of the trolley belt 214 of the sorting trolley 2 along the radial direction (Y direction) of the driving gear 311, so that the tooth structure of the trolley belt 214 is in a meshing state with the driving gear 311 of the movable driving gear mechanism 7, and then controlling the driving device 712 of the movable driving gear mechanism 7 to move, driving the driving gear 311 to rotate When the sorting work is completed, the lifting mechanism 711 of the movable driving gear mechanism 7 is controlled to move again, driving the driving device 712 and the driving gear 311 to descend back to their original positions; when the sorting trolley 2 moves to the A1 sorting location, at this time, when sorting is not required at the A1 sorting location, the lifting mechanism 711 of the movable driving gear mechanism 7 does not move, so that the driving gear 311 and the trolley belt 214 of the sorting trolley 2 are in a state of separation from each other, which facilitates the smooth passage of the sorting trolley 2. Through the above design, the structure of the sorting trolley is greatly simplified while the sorting function of the sorting trolley is retained, so that when the sorting trolley needs to be sorted at the sorting location, it can perform sorting work normally, and can continue to move smoothly along the track when sorting is not required. In addition, when sorting is not required at the sorting location, the driving gear and the trolley belt are in a separated state, and the driving gear and the trolley belt are only in contact during sorting, which can also reduce the wear between the two and increase the service life. Therefore, this embodiment ensures that the sorting trolley can perform normal sorting work while further simplifying the overall structure of the sorting trolley and reducing the manufacturing cost and maintenance cost; further realizes the lightweighting of the sorting trolley, reduces the overall weight of the sorting trolley, improves the reliability and service life of the cross-belt sorter, and reduces the use cost such as energy consumption.

[0038] Here, it should be noted that, when sorting is required at the sorting location, the sorting trolley can also be controlled to stop moving, and the movable driving gear mechanism can be controlled to move, so as to drive the driving gear of the movable driving gear mechanism to move until it contacts the trolley belt of the sorting trolley, so that the driving gear is inserted into the belt transmission tooth of the trolley belt of the sorting trolley, thereby making the tooth structure of the trolley belt and the driving gear of the movable driving gear mechanism in a meshing state; the driving gear of the movable driving gear mechanism is controlled to rotate, thereby driving the trolley belt of the sorting trolley to rotate, and the sorting work is started. After the sorting work is completed, the movable driving gear mechanism is controlled to move, so that the driving gear of the movable driving gear mechanism is separated from the trolley belt of the sorting trolley, and the sorting trolley continues to move.

[0039] Example 4: Compared to Example 3, this embodiment differs in that the cross-belt sorting machine further includes a belt conveyor at each sorting station. A belt conveyor 6 is provided at sorting stations A1 through A6. One end of the trolley belt 214 of the sorting trolley 2 moving to the sorting station is positioned adjacent to one end of the transmission belt of the belt conveyor 6, allowing items to be sorted on the trolley belt to be transferred to the transmission belt, or vice versa. When fragile items are being sorted, the trolley belt 214 of the sorting trolley 2 first transports the items to the belt conveyor 6 and then sorts the items off the belt conveyor 6. This prevents fragile items from falling and being damaged during transport by the trolley belt 214 of the sorting trolley 2, thus ensuring the integrity of the sorted items.

[0040] like Figure 17 As shown, the basic structure of the belt conveyor 6 is the same as that of the sorting trolley, that is, it also includes a conveyor body 612, a roller 3 613 and a roller 4 614 rotatably connected to the conveyor body 612, and a transmission belt 611 is connected between the roller 3 613 and the roller 4 614 in a coordinated transmission manner. The transmission belt can be driven by providing a separate driving mechanism, such as providing a separate motor to drive the transmission belt 611 of the belt conveyor 6. However, in this embodiment, as shown in FIG. Figure 17 As shown, the driving power of the transmission belt 611 and the driving power of the trolley belt 214 are both achieved through the drive gear 311. Specifically, the outer surface of the transmission belt 611 of the belt conveyor 6 is also provided with a toothed structure, and the tooth profile of the transmission belt 611 matches the tooth profile of the drive gear 311. When sorting is performed at the sorting station, the lifting mechanism 711 of the movable drive gear mechanism 7 is controlled to drive the drive device 712 and the drive gear 311 upward. The drive gear 311 is simultaneously inserted into the belt drive teeth 2141 below the end of the trolley belt 214 and the teeth below the end of the transmission belt 611, so that the drive gear 311 meshes with the toothed structures of the trolley belt 214 and the transmission belt 611. This design allows the transmission belt 611 and the trolley belt 214 to rotate simultaneously during sorting (as indicated by the arrows in the figure), further simplifying the structure of the cross-belt sorter and reducing manufacturing and maintenance costs.

[0041] Example 5: Compared with Example 3 and Example 4, the difference is that: Figure 18As shown, the movable driving gear mechanism 7 is a swinging mechanism, which includes a frame 8, two swing arms 9, a cylinder 10 and a driving device (not shown in the figure). The driving device can adopt a driving motor. One end of the two swing arms 9 is hinged on the frame 8 (such as the hinge point B in the figure), and the driving gear 311 is connected to the shaft 11. The two ends of the shaft 11 are respectively rotatably connected to the other ends of the two swing arms 9 through bearings, so that the driving gear 311 is rotatably connected to the position between the two swing arms 9. The driving motor (not shown in the figure) is connected to one of the swing arms 9 and the output shaft of the driving motor is in transmission connection with the shaft 11, so that under the drive of the driving motor, the driving gear 311 can be driven to rotate; the cylinder body of the cylinder 10 is hinged to the frame 8, and the piston rod 101 of the cylinder 10 is hinged to the other swing arm 9, so that under the action of the cylinder 10, the two swing arms 9 can be driven to swing back and forth.

[0042] When the sorting trolley 2 moves to the A1 sorting location, at this time, when sorting is required at the A1 sorting location, the cylinder 10 of the movable driving gear mechanism 7 is controlled to operate, and the two swing arms 9 are swung in the direction close to the trolley belt 214 of the sorting trolley 2, so that the driving gear 311 contacts one end of the trolley belt 214 of the sorting trolley 2, thereby inserting the driving gear 311 into the belt transmission tooth 2141 below the end of the trolley belt 214 of the sorting trolley 2 along the radial direction (Y direction) of the driving gear 311, so that the tooth structure of the trolley belt 214 is in a meshing state with the driving gear 311 of the movable driving gear mechanism 7, and then the driving motor (not shown in the figure) of the movable driving gear mechanism 7 is controlled to operate to drive the driving gear 311 to rotate, thereby driving the trolley belt 214 of the sorting trolley 2 to rotate, and starting the sorting work; When the sorting trolley 2 moves to the A1 sorting location, at this time, when sorting is not required at the A1 sorting location, the cylinder 10 of the movable driving gear mechanism 7 does not move, so that the driving gear 311 and the trolley belt 214 of the sorting trolley 2 are in a state of separation from each other, which facilitates the smooth passage of the sorting trolley 2.

[0043] Example 6: Compared to Example 5, this embodiment differs in that the cross-belt sorting machine further includes a belt conveyor at each sorting station. A belt conveyor 6 is provided at sorting stations A1 through A6. One end of the trolley belt 214 of the sorting trolley 2 moving to the sorting station is positioned adjacent to one end of the transmission belt of the belt conveyor 6, allowing items to be sorted on the trolley belt to be transferred to the transmission belt, or vice versa. When fragile items are being sorted, the trolley belt 214 of the sorting trolley 2 first transports the items to the belt conveyor 6 and then sorts the items off the belt conveyor 6. This prevents fragile items from falling and being damaged during transport on the trolley belt 214 of the sorting trolley 2, thus ensuring the integrity of the sorted items.

[0044] like Figure 19 As shown, the basic structure of the belt conveyor 6 is the same as that of the sorting trolley, that is, it also includes a conveyor body 612, a roller 3 613 and a roller 4 614 rotatably connected to the conveyor body 612, and a transmission belt 611 is connected between the roller 3 613 and the roller 4 614 in a coordinated transmission manner. The transmission belt can be driven by providing a separate driving mechanism, such as providing a separate motor to drive the transmission belt 611 of the belt conveyor 6. However, in this embodiment, as shown in FIG. Figure 19 As shown, the driving power of the transmission belt 611 and the driving power of the trolley belt 214 are both driven by the drive gear 311. Specifically, the outer surface of the transmission belt 611 of the belt conveyor 6 is also provided with a toothed structure, and the tooth profile of the transmission belt 611 matches the tooth profile of the drive gear 311. A transmission gear 615 is also provided on the outer side of one end of the transmission belt 611, which rotates synchronously with the transmission belt 611. In this embodiment, the transmission gear 615 is coaxially arranged with the roller 4 614 and rotates synchronously with the roller 4 614. The transmission gear 615 is in meshing engagement with the drive gear 311. The frame 8 of the movable drive gear mechanism is fixedly connected to the transmission carriage 612 of the belt conveyor.

[0045] When sorting is performed at the sorting station, the cylinder 10 controlling the movable drive gear mechanism 7 is actuated to drive the two swing arms 9 to swing toward the trolley belt 214 of the sorting trolley 2. During the swinging process, the transmission gear 615 and the drive gear 311 are always in a meshing state. When swung into place, the drive gear 311 is simultaneously meshed with the toothed structures of the trolley belt 214 and the transmission belt 611 for transmission connection.

[0046] Example 7: Compared with Example 3, the difference is that: Figure 20As shown, the up and down lifting mechanism includes a lifting mechanism 711, a transmission device 713 and a driving device 712. The driving gear 311 is rotatably connected to the lifting mechanism 711. The driving device 712 drives the driving gear 311 to rotate through the transmission device 713. The lifting mechanism 711 can drive the driving gear 311 to move up and down together.

[0047] When sorting is required at the A1 sorting location, the lifting mechanism 711 of the movable driving gear mechanism 7 is controlled to operate, driving the driving gear 311 to rise, so that the driving gear 311 contacts one end of the trolley belt 214 of the sorting trolley 2, thereby inserting the driving gear 311 into the belt transmission tooth 2141 below the end of the trolley belt 214 of the sorting trolley 2 along the radial direction (Y direction) of the driving gear 311, so that the tooth structure of the trolley belt 214 is in a meshing state with the driving gear 311 of the movable driving gear mechanism 7, and then the driving device 712 of the movable driving gear mechanism 7 is controlled to operate, driving the driving gear 311 to rotate, thereby driving the trolley belt 214 of the sorting trolley 2 to rotate, and starting the sorting work.

[0048] like Figure 21 As shown, the lifting mechanism 711 can be a lifting cylinder, and the driving device can be a driving motor, which is fixedly installed and remains stationary during operation. The transmission device 1 713 includes a support 1 7131 provided on the piston rod of the lifting cylinder and a transmission shaft 1 7132 rotatably connected to the support 1 7131. The driving gear 311 is connected to the transmission shaft 1 7132, and the transmission shaft 1 7132 is also connected to the synchronous transmission gear 1 7133. The output shaft of the driving motor is provided with a gear 2 12. The gear 2 12 and the synchronous transmission gear 1 7133 are connected by a synchronous belt 13, so that the driving device can drive the driving gear 311 to rotate.

[0049] Example 8: Compared with Example 5, the difference is that: Figure 22 As shown, the swing mechanism includes a frame (not shown in the figure), a swing arm 9 and a cylinder 10. The cylinder 10 is hinged on the frame (not shown in the figure). The piston rod of the cylinder 10 is hinged to the swing arm 9. One end of the swing arm 9 is fixed, so that under the action of the cylinder 10, the other end of the swing arm 9 can be driven to swing back and forth around its fixed end, and the driving gear 311 is rotatably connected to the other end of the swing arm 9; a transmission device 2 14 is also provided on the swing arm 9, and the driving device 712 is transmission-connected to the driving gear 311 through the transmission device 2 14, so that under the action of the driving device 712, the driving gear 311 can be driven to rotate.

[0050] When the sorting trolley 2 moves to the A1 sorting location, at this time, when sorting is required at the A1 sorting location, the cylinder 10 of the movable driving gear mechanism 7 is controlled to move, and the swing arm 9 is swung in the direction close to the trolley belt 214 of the sorting trolley 2, so that the driving gear 311 contacts one end of the trolley belt 214 of the sorting trolley 2, thereby inserting the driving gear 311 into the belt transmission tooth 2141 below the end of the trolley belt 214 of the sorting trolley 2 along the radial direction (Y direction) of the driving gear 311, so that the tooth structure of the trolley belt 214 is in a meshing state with the driving gear 311 of the movable driving gear mechanism 7, and then the driving device of the movable driving gear mechanism 7 is controlled to move, driving the driving gear 311 to rotate, thereby driving the trolley belt 214 of the sorting trolley 2 to rotate, and starting the sorting work.

[0051] like Figure 23 As shown, shaft 15 passes through the swing arm 9 and is rotatably connected to the other end of the swing arm 9, and the driving gear 311 is connected to one end of the shaft 15, so that the driving gear 311 is rotatably connected to the other end of the swing arm 9; shaft 2 16 passes through the swing arm 9 and is rotatably connected to one end of the swing arm 9, and the transmission device 2 14 includes a synchronous gear 141 arranged on the other end of the shaft 15, a synchronous gear 2 142 arranged on the other end of the shaft 2 16, and a synchronous belt 13 that is connected between the synchronous gear 141 and the synchronous gear 2 142 for cooperative transmission. The output shaft of the driving device 712 is transmission-connected to one end of the shaft 2 16, so that the driving gear 311 can be driven to rotate under the action of the driving device 712.

[0052] Example 9: Compared with Example 3, the difference is that: Figure 24 As shown, in this embodiment, the movable driving gear mechanism 7 is a horizontal movable mechanism, which includes a horizontal moving mechanism 714, a driving gear 311 rotatably connected to the horizontal moving mechanism 714, a transmission device three 17 and a driving device 712. The driving device 712 is connected to the driving gear 311 through the transmission device three 17, so that under the action of the driving device 712, the driving gear 311 can be driven to rotate.

[0053] When the sorting trolley 2 moves to the A1 sorting location, at this time, when sorting is required at the A1 sorting location, the horizontal moving mechanism 714 of the movable driving gear mechanism 7 is controlled to move, and the driving gear 311 moves horizontally, so that the driving gear 311 contacts one end of the trolley belt 214 of the sorting trolley 2, thereby inserting the driving gear 311 into the belt transmission tooth 2141 below the end of the trolley belt 214 of the sorting trolley 2 along the radial direction (Y direction) of the driving gear 311, so that the tooth structure of the trolley belt 214 is in a meshing state with the driving gear 311 of the movable driving gear mechanism 7, and then the driving device 712 of the movable driving gear mechanism 7 is controlled to move, driving the driving gear 311 to rotate, thereby driving the trolley belt 214 of the sorting trolley 2 to rotate, and starting the sorting work.

[0054] like Figure 25 As shown, the horizontal moving mechanism 714 can adopt a cylinder, and a support 2 18 is provided on the piston rod of the cylinder, and a shaft 3 19 is rotatably connected to the support 2 18, and the driving gear 311 is connected to the shaft 3 19. The transmission device 3 17 includes a synchronous gear 3 171 provided on the shaft 3 19, a synchronous gear 4 172 connected to the rotating shaft of the driving device 712, and a synchronous belt 13 that is connected between the synchronous gear 3 171 and the synchronous gear 4 172 for cooperative transmission.

[0055] In summary, while greatly simplifying the structure of the sorting trolley, the sorting function of the sorting trolley is retained, so that when the sorting trolley needs to be sorted at the sorting location, it can perform sorting work normally, and when sorting is not required, it can continue to move smoothly along the track. Therefore, the present invention ensures that the sorting trolley can perform normal sorting work while further simplifying the overall structure of the sorting trolley, reducing manufacturing costs and maintenance costs; further achieving lightweighting of the sorting trolley, reducing the overall weight of the sorting trolley, improving the reliability and service life of the cross-belt sorter, and reducing energy consumption and other usage costs. By providing an angled end at one end of the trolley belt and one end of the drive gear, the belt drive teeth can be smoothly inserted into the teeth of the drive gear to form a chimeric state. By further designing the redundant rotation amount of the drive gear, when one end of the trolley belt contacts one end of the drive gear, the axial force F applied by the insertion of the trolley belt allows the drive gear to flexibly rotate within the redundant rotation amount to a certain angle without driving the drive motor's shaft to rotate, thereby creating a misalignment with the one end of the trolley belt. This allows the belt drive teeth to smoothly insert between the teeth of the drive gear, forming a chiseled state. At the same time, when the drive motor's shaft rotates beyond the designed redundant rotation amount, it can still drive the drive gear to rotate normally, ensuring the normal progress of the sorting work. By also providing a belt conveyor at each sorting station, when the sorted goods are fragile, the trolley belt of the sorting trolley can first transport the goods to the belt conveyor, and then sort the goods from the belt conveyor. This prevents fragile goods from directly falling and being damaged during the conveying process of the sorting trolley belt, ensuring the integrity of the sorted goods. When sorting, the same drive gear can drive the transmission belt and the trolley belt to rotate at the same time, further simplifying the structure of the cross-belt sorter and reducing manufacturing and maintenance costs.

The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Persons skilled in the art may make various modifications or alterations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of protection of the present invention, which is defined by the claims.
