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] The cross-belt sorting machine, also known as the cross-belt sorting system, is a highly automated logistics equipment widely used in express delivery, postal services, e-commerce warehousing and other fields. The cross-belt sorting machine is mainly composed of a main drive belt conveyor and a sorting trolley. The main drive belt conveyor drives the sorting trolley to move, and the goods to be sorted are placed on the sorting trolley; when the sorting trolley moves to the specified sorting position, the belt on the sorting trolley is driven to rotate, thereby completing the sorting of the goods. Because the main drive belt conveyor and the belt on the sorting trolley are in a cross shape, it is called a cross-belt sorting machine.

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

[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 rail, a sorting trolley and a sorting port electromagnetic control device, wherein the sorting trolley is slidably mounted on the sorting slide rail; the sorting trolley includes a bottom plate, a roller, a roller and a driving gear, wherein the roller is rotatably mounted on the bottom plate and the roller is in contact with the sorting slide rail, wherein the number of the rollers is at least two, and all of them are rotatably mounted on the top surface of the bottom plate, a conveyor belt is wound on the roller, and a driving rod is rotatably mounted on the bottom plate, wherein the upper end of the driving rod is meshed with a driven bevel gear on the top surface of the bottom 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 driving box. The mounting plate is slidably installed on the top surface of the control box, and the driving box is installed on the top surface of the mounting plate and the driving box is at the same height as the driving gear; a sliding rod is provided inside the driving box, and the driving box has an opening on the side facing the driving gear, a part of the sliding rod extends out of the opening, and a rack plate matching the driving gear is installed on the side of the sliding rod facing the driving gear, the length of the opening on the driving box is greater than the length of the sliding rod, and the sliding rod is connected to the inner side of the driving box through a buffer spring on two opposite sides in the length direction.

[0005] In the above patent document, the rotation drive of the conveyor belt of the sorting trolley is realized by the meshing of the rack plate in the sorting port electromagnetic control device arranged at the sorting port and the driving gear installed on the sorting trolley. In the patent document, a part of the mechanism driving the conveyor belt rotation, namely the sorting port electromagnetic control device with the rack plate, is separated from the sorting trolley and is not designed as an integrated structure with the sorting trolley. Although this can reduce the overall weight of the sorting trolley to a certain extent, the transmission mechanism with the driving gear is still arranged on the sorting trolley, which will also make the overall structure of the sorting trolley more complicated, thereby increasing the manufacturing cost and maintenance cost. In addition, the weight of the sorting trolley is still relatively heavy, which reduces the reliability and service life of the cross-belt sorter and increases the use cost such as energy consumption.

[0006] In summary, how to redesign a sorting method of a sorting trolley and a cross-belt sorter so that they can ensure the normal sorting work of the sorting trolley while further simplifying the overall structure of the sorting trolley and reducing manufacturing and maintenance costs; further realizing the lightweight 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 use costs are technical problems that need to be solved urgently.

By also setting a belt conveyor at each sorting point, 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 out of the belt conveyor. In this way, fragile goods are prevented from falling directly and being damaged during the conveying process of the trolley belt of the sorting trolley, and the integrity of the sorted goods is ensured. When sorting, the same driving gear can be used to 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 in conjunction with the accompanying drawings and specific embodiments.

[0025] The present application discloses a sorting working method of a sorting trolley, wherein the outer surface of a trolley belt of the sorting trolley is set as 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: Embodiment 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 arranged, such as Figure 1 Six sorting places are provided, namely A1 to A6. A fixed drive gear mechanism 3 is provided at each sorting place. 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 roller 1 212 and a roller 213 rotatably connected to the body 211, and a trolley belt 214 is also connected between the roller 1 212 and the roller 2 213 for transmission. The trolley belt 214 is an annular belt, and the outer surface of the annular belt is set as a toothed structure, that is, a plurality of belt transmission teeth 2141 are set on the outer surface of the annular belt. The roller 1 212 and the roller 2 213 are respectively set at the inner two ends of the annular belt, and the rotation of the trolley belt 214 can drive the roller 1 212 and the roller 2 213 to rotate. A pulley 215 is also set at the bottom of the body 211, and a plurality of sorting trolleys 2 are slidably connected to the track 111 of the conveyor 1 through the pulley 211 at the bottom thereof. 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 cyclically along the track 111 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 toward the sorting position A1 along the straight section of the track 111. 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, with 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 perform sorting at the A1 sorting point, the fixed driving gear mechanism 3 is controlled to be in a stop state, and with 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 place, it can perform the sorting work normally, and when it does not need to be sorted, 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 the manufacturing cost and maintenance cost; further realizing the lightweight 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 the use cost such as energy consumption.

[0029] Here, it should be noted that when sorting is required at the sorting point, 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 drive tooth 2141 at the end of the trolley belt 214 of the sorting trolley 2 is inserted into the driving gear 311 along the axial direction (X direction, as shown by the solid arrow in the figure) of the driving gear 311 of the fixed driving gear mechanism 3 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 drive tooth 2141 are in contact. Therefore, in order to avoid the above-mentioned two end faces colliding with each other and affecting the insertion of the belt drive 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 Fig. 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 and the gear bevel end 3111 at one end of the driving gear 311 are used to cooperate and contact, 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 only 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 made further optimizations, namely: Figure 7 As shown, the driving gear 311 is designed to have a certain amount of redundant rotation relative to the driving device (as shown by the hollow arrow in the figure, the driving gear can rotate a certain angle relative to the rotating shaft of the driving device and then be limited to form an integrated structure with the rotating shaft). In this way, when one end of the trolley belt 214 contacts one end of the driving gear 311, the driving gear 311 will be subjected to the axial force F inserted by the one end of the trolley belt 214, so that the driving gear 311 can flexibly rotate a certain angle within the redundant rotation amount without driving the rotating shaft 3121 of the driving motor to rotate together, so that the teeth of the driving gear and the teeth of the belt transmission teeth are misaligned with each other, and finally the belt transmission teeth can be smoothly inserted into the teeth of the driving gear to form a fitting state; at the same time, when the rotating shaft of the driving motor rotates beyond the designed redundant rotation amount, the driving gear is limited to form an integrated structure with the rotating shaft, so that the driving gear can still be driven to rotate normally by the driving motor, thereby ensuring the normal progress of the sorting work.

[0031] The redundant rotating structure may adopt the redundant rotating structure of some motors themselves, or may adopt a redundant rotating structure provided by the following applicants, such as Figures 10 to 12As shown, the driving device is a driving motor 312, and the driving gear 311 is sleeved on the rotating shaft 3121 of the driving motor 312 through the bearing 4. The rotating shaft 3121 is provided with a rotating shaft flange 3122, and a lever 5 is provided on the rotating shaft flange 3122. The axial direction of the lever 5 is parallel to the axial direction of the rotating shaft 3121. There are multiple levers 5, and the multiple levers 5 are sequentially arranged along the circumferential direction. An arc groove 3112 cooperating with the lever 5 is provided on the end surface of the driving gear 311, and there are multiple arc grooves 3112, and the positions thereof correspond to the levers 5. When the driving gear 311 is sleeved on the rotating shaft 3121 of the driving motor 312 through the bearing 4, the lever 5 is inserted into the arc groove 3112, so that a redundant rotation structure is formed between the driving gear 311 and the rotating shaft 3121. Here, since the driving gear 311 is sleeved on 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, the lever 5 is driven 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 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 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 with 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 lever 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] Embodiment 2: Compared with Embodiment 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 Fig.13As shown, belt conveyors 6 are provided at sorting locations A1 to A6, and one end of the trolley belt 214 of the sorting trolley 2 moved to the sorting location is adjacent to one end of the transmission belt of the belt conveyor 6, so that the goods to be sorted on the trolley belt 214 can be transferred to the transmission belt or the goods to be sorted on the transmission belt can be transferred to the trolley belt 214. When the sorted goods are fragile, the goods can be first transported to the belt conveyor 6 by the trolley belt 214 of the sorting trolley 2, and then the goods can be sorted out from the belt conveyor 6. In this way, fragile goods are prevented from falling directly and being damaged during the transportation process of the trolley belt 214 of the sorting trolley 2, and the integrity of the sorted goods is ensured.

[0033] like Fig.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 setting a separate driving mechanism, such as setting a separate motor to drive the transmission belt 611 of the belt conveyor 6 to rotate. However, in this embodiment, as shown in FIG. Fig.14 As shown, the driving power of the transmission belt 611 and the driving power of the trolley belt 214 are both driven by the driving gear 311, that is, the outer surface of the transmission belt 611 of the belt conveyor 6 is also set to a toothed structure, and the tooth shape of the transmission belt 611 matches the tooth shape of the driving gear 311. The driving gear 311 of the fixed driving gear mechanism 3 is meshed and connected with the toothed structure of the transmission belt 611. With this design, when sorting, the same driving gear 311 can be used to drive the transmission belt 611 and the trolley belt 214 to rotate at the same time (as shown by the arrow in the figure), which further simplifies the structure of the cross-belt sorter and reduces the manufacturing cost and maintenance cost.

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

[0035] like Fig.15As shown, in this embodiment, the movable driving gear mechanism 7 is an up-and-down lifting mechanism, which includes a lifting mechanism 711, a driving device 712 arranged on the lifting mechanism 711, and a driving gear 311 arranged on the driving device. The lifting mechanism 711 can drive the driving device 712 and the driving gear 311 to lift up and down together, and the driving device can drive the driving gear 311 to rotate. In this embodiment, the lifting mechanism 711 can use a lifting cylinder, and the driving device can use a driving motor. The tooth shape of the driving gear 311 matches the tooth shape 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 position A1. The sorting trolley 2 moves toward the sorting position A1 along the straight section of the track 111. When the sorting trolley 2 moves to the sorting position A1, at this time, when sorting is required at the sorting position A1, Fig.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 the driving device 712 of the movable driving gear mechanism 7 is controlled to move, driving the driving gear 311 to rotate. The sorting trolley 2 moves, thereby driving the trolley belt 214 of the sorting trolley 2 to rotate and start the sorting work. During the sorting work, the sorting trolley 2 keeps moving. 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 is convenient for 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 place, it can perform the 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 place, the driving gear and the trolley belt are in a separated state, and the driving gear and the trolley belt are only allowed to 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, and further simplifies the overall structure of the sorting trolley, reduces the manufacturing cost and maintenance cost; further realizes the lightweight 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 point, 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, so that the tooth structure of the trolley belt and the driving gear of the movable driving gear mechanism are in a meshing state; the driving gear of the movable driving gear mechanism is controlled to rotate, so as to drive 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] Embodiment 4: Compared with Embodiment 3, the difference is that the cross-belt sorting machine of this embodiment also includes a belt conveyor arranged at each sorting place. A belt conveyor 6 is arranged at sorting place A1 to sorting place A6. One end of the trolley belt 214 of the sorting trolley 2 moved to the sorting place is arranged adjacent to one end of the transmission belt of the belt conveyor 6, so that the goods to be sorted on the trolley belt can be transferred to the transmission belt or the goods to be sorted on the transmission belt can be transferred to the trolley belt. When the sorted goods are fragile goods, the trolley belt 214 of the sorting trolley 2 can first transport the goods to the belt conveyor 6, and then sort the goods out from the belt conveyor 6. In this way, fragile goods are prevented from falling directly and being damaged during the transmission process of the trolley belt 214 of the sorting trolley 2, and the integrity of the sorted goods is ensured.

[0040] like Fig.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 setting a separate driving mechanism, such as setting a separate motor to drive the transmission belt 611 of the belt conveyor 6 to rotate. However, in this embodiment, as shown in FIG. Fig.17 As shown, the driving power of the transmission belt 611 and the driving power of the trolley belt 214 are both driven by the driving gear 311, that is, the outer surface of the transmission belt 611 of the belt conveyor 6 is also set to a toothed structure, and the tooth shape of the transmission belt 611 matches the tooth shape of the driving gear 311. When sorting is performed at the sorting place, the lifting mechanism 711 of the movable driving gear mechanism 7 is controlled to drive the driving device 712 and the driving gear 311 to rise together, and the driving gear 311 is inserted into the belt transmission teeth 2141 below the end of the trolley belt 214 and the teeth below the end of the transmission belt 611 at the same time, so that the driving gear 311 is meshed and connected with the toothed structures of the trolley belt 214 and the transmission belt 611 at the same time. With this design, when sorting is performed, the same driving gear 311 can be used to drive the transmission belt 611 and the trolley belt 214 to rotate at the same time (as shown by the arrow in the figure), further simplifying the structure of the cross-belt sorting machine and reducing the manufacturing cost and maintenance cost.

[0041] Embodiment 5: Compared with Embodiment 3 and Embodiment 4, the difference is that: Fig.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 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 matched with the shaft 11 for transmission connection, 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 move, 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 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; 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] Embodiment 6: Compared with Embodiment 5, the difference is that the cross-belt sorting machine of this embodiment also includes a belt conveyor arranged at each sorting place. A belt conveyor 6 is arranged at sorting place A1 to A6. One end of the trolley belt 214 of the sorting trolley 2 moved to the sorting place is arranged adjacent to one end of the transmission belt of the belt conveyor 6, so that the goods to be sorted on the trolley belt can be transferred to the transmission belt or the goods to be sorted on the transmission belt can be transferred to the trolley belt. When the sorted goods are fragile goods, the trolley belt 214 of the sorting trolley 2 can first transport the goods to the belt conveyor 6, and then sort the goods out from the belt conveyor 6. In this way, fragile goods are prevented from falling directly and being damaged during the transmission process of the trolley belt 214 of the sorting trolley 2, and the integrity of the sorted goods is ensured.

[0044] like Fig.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 setting a separate driving mechanism, such as setting a separate motor to drive the transmission belt 611 of the belt conveyor 6 to rotate. However, in this embodiment, as shown in FIG. Fig.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 driving gear 311, that is, the outer surface of the transmission belt 611 of the belt conveyor 6 is also set to a toothed structure, and the tooth shape of the transmission belt 611 matches the tooth shape of the driving gear 311. A transmission gear 615 that rotates synchronously with the transmission belt 611 is also set at the outer side of one end of the transmission belt 611. In this embodiment, the transmission gear 615 is coaxially arranged with the roller four 614 and the transmission gear 615 rotates synchronously with the roller four 614. The transmission gear 615 is in a meshing state with the driving gear 311. The frame 8 of the movable driving gear mechanism is fixedly connected to the transmission machine body 612 of the belt conveyor.

[0045] When sorting work is carried out at the sorting point, the cylinder 10 controlling the movable driving gear mechanism 7 is actuated to drive the two swing arms 9 to swing toward the direction of the trolley belt 214 close to the sorting trolley 2. During the swinging process, the transmission gear 615 and the driving gear 311 are always in a meshing state. When swung into place, the driving gear 311 is meshed and connected with the toothed structures of the trolley belt 214 and the transmission belt 611 at the same time.

[0046] Embodiment 7: Compared with Embodiment 3, the difference is that: Fig. 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 Fig.21 As shown, the lifting mechanism 711 can adopt a lifting cylinder, and the driving device can adopt a driving motor, which is fixedly installed and remains motionless during operation. The transmission device 1 713 includes a support 1 7131 arranged 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 a synchronous transmission gear 1 7133 is also connected to the transmission shaft 1 7132. A gear 2 12 is arranged on the output shaft of the driving motor, and 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] Embodiment 8: Compared with Embodiment 5, the difference is that: Fig. 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 Fig.23 As shown, shaft one 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 one 15, so that the driving gear 311 is rotatably connected to the other end of the swing arm 9; shaft two 16 passes through the swing arm 9 and is rotatably connected to one end of the swing arm 9, and the transmission device two 14 includes a synchronous gear one 141 arranged on the other end of the shaft one 15, a synchronous gear two 142 arranged on the other end of the shaft two 16, and a synchronous belt 13 that is connected between the synchronous gear one 141 and the synchronous gear two 142 for cooperative transmission, and the output shaft of the driving device 712 is transmission-connected to one end of the shaft two 16, so that the driving gear 311 can be driven to rotate under the action of the driving device 712.

[0052] Embodiment 9: Compared with Embodiment 3, the difference is that: Fig.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 3 17 and a driving device 712. The driving device 712 is connected to the driving gear 311 through the transmission device 3 17, so that the driving gear 311 can be driven to rotate under the action of the driving device 712.

[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, drive the driving gear 311 to rotate, thereby driving the trolley belt 214 of the sorting trolley 2 to rotate, and start sorting.

[0054] like Fig.25 As shown, the horizontal moving mechanism 714 can adopt a cylinder, a support 2 18 is arranged on the piston rod of the cylinder, a shaft 3 19 is rotatably connected to the support 2 18, a driving gear 311 is connected to the shaft 3 19, and the transmission device 3 17 includes a synchronous gear 3 171 arranged 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, the structure of the sorting trolley is greatly simplified while retaining the sorting function of the sorting trolley, so that the sorting trolley can perform sorting work normally when it needs to be sorted at the sorting place, and can smoothly continue to move along the track when it does not need to be sorted. 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 realizing the lightweight of the sorting trolley, reducing the overall weight of the sorting trolley, improving the reliability and service life of the cross-belt sorting machine, and reducing energy consumption and other use costs. By setting an angled end at one end of the trolley belt and one end of the driving gear, the belt drive teeth can be smoothly inserted into the teeth of the driving gear to form a chimeric state. By further designing the redundant rotation amount of the driving gear, when one end of the trolley belt contacts one end of the driving gear, due to the axial force F inserted by one end of the trolley belt, the driving gear can flexibly rotate a certain angle within the redundant rotation amount, and will not drive the shaft of the driving motor to rotate together, thereby forming a misalignment with one end of the trolley belt, so that the belt transmission teeth can be smoothly inserted into the teeth of the driving gear to form an interlocking state; at the same time, when the shaft of the driving motor rotates more than the designed redundant rotation amount, it can still drive the driving gear to rotate normally, ensuring the normal progress of the sorting work. By also setting a belt conveyor at each sorting point, 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 out of the belt conveyor. In this way, fragile goods are prevented from falling directly and being damaged during the conveying process of the trolley belt of the sorting trolley, and the integrity of the sorted goods is ensured. When sorting, the same driving gear can be used to 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.

Those skilled in the relevant technical field can make various changes or modifications without departing from the spirit and scope of the present invention.
