Description

Technical Field

[0001] The present invention relates to the technical field of sorting equipment, and in particular to a sorting method of a sorting trolley and a cross-belt sorting machine. Background Art

[0002] At present, when a cross-belt sorter is sorting goods, it is necessary to drive the belt on the sorting trolley to rotate. The usual practice is to set a belt driving mechanism on the sorting trolley and use the belt driving mechanism to drive the belt of the sorting trolley to rotate. However, setting the belt driving mechanism on the sorting trolley will make the overall structure of the sorting trolley complicated, resulting in high manufacturing and maintenance costs. In addition, it will make the weight of the sorting trolley heavier, reducing the reliability and service life of the cross-belt sorter.

[0003] 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.

[0004] 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.

[0005] In summary, how to redesign a sorting method for 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.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the embodiments of the invention more clear, the following will be combined with the appended drawings of the embodiments of the invention to Figure 1-13 , clearly and completely describe the technical solutions of the embodiments of the invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0021] It should be noted that all directional indications (such as up, down, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship of the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] Embodiment 1: Figure 1 As shown, the present application also provides a cross-belt sorting machine, including a conveyor 7 and a plurality of sorting carts 1 arranged on the track 71 of the conveyor 7, wherein the plurality of sorting carts 1 are slidably connected to the track 71 of the conveyor 7 and driven by the conveyor 7 to drive the plurality of sorting carts 1 to move along the track 71 of the conveyor 7, and a plurality of sorting locations are arranged on the path where the sorting carts 1 move along the straight section of the track 71, and the sorting carts 1 drive the cart belt 15 to rotate through the belt drive structure 2 of the sorting cart 1. In the present embodiment, the track 71 is a horizontal annular track, that is, the track 71 is arranged in a ring shape on the horizontal plane, and here, the track 71 can also be arranged as a vertical annular track, that is, the track 71 is arranged in a ring shape on the vertical plane. The conveyor 7 can adopt a main drive belt conveyor, which adopts a conveyor belt 72 to drive the sorting cart 1 to move along the track 71.

[0023] There are multiple sorting locations along the path where the sorting trolley 1 moves along the straight track. Figure 1 Six sorting places are provided, namely A1 to A6. A fixed drive gear mechanism 23 is provided at each sorting place. In this embodiment, the fixed drive gear mechanism 23 is provided on a component other than the track 71. Here, the fixed drive gear mechanism 3 can also be provided on the side of the track 71 of the conveyor 7.

[0024] like Figures 1 to 6 As shown, the sorting trolley 1 includes a body 11, a roller 13 and a roller 14 rotatably connected to the body 11, and a trolley belt 15 is also connected between the roller 13 and the roller 14 for transmission. The trolley belt 15 is annularly wound around the roller 13 and the roller 14, so that the roller 13 and the roller 14 are respectively located at the two ends of the inner part of the trolley belt; the belt driving structure 2 of the trolley belt 15 includes a gear 21 and a driving gear mechanism 22 arranged on the roller 13 or the roller 14, the gear 21 is coaxial with the roller 13 or the roller 14, and the gear 21 is installed at the end of the roller 13 or the roller 14, so that the gear 21 and the roller 13 or the roller 14 can rotate synchronously; the driving gear mechanism 22 is arranged at the sorting place, and multiple sorting trolleys 1 are slidably connected to the track 71 of the conveyor 7 through the pulley 12 at the bottom thereof. When the sorting trolley 1 moves to the driving gear mechanism 22, the driving gear 221 of the driving gear mechanism 22 meshes with the gear 1 21 for transmission, thereby driving the trolley belt 15 to rotate for sorting. When sorting is not required or the sorting is completed, the driving gear mechanism 22 can be separated from the gear 1 21 on the sorting trolley 1, the trolley belt 15 is in a stopped state, and the sorting trolley 1 passes through the sorting location smoothly.

[0025] It should be noted that the gear 1 21 can be one or two. When there is one gear 1 21, the gear 1 21 is installed at one end of the roller 1 13 or at one end of the roller 2 14; when there are two gear 1 21, the two gear 1s 21 are installed at both ends of the roller 1 13 or at both ends of the roller 2 14.

[0026] In this embodiment, if Figure 2 As shown, the driving gear mechanism 22 of the belt driving structure 2 is a fixed driving gear mechanism 23, which includes a driving mechanism 1 222 and a driving gear 221 disposed on the driving mechanism 1 222, and the tooth shape of the driving gear 221 matches the tooth shape of the gear 1 21. The axial direction of the gear 1 21 is parallel to the axial direction of the driving gear 221.

[0027] It should be noted that the driving mechanism 222 in this embodiment can adopt a servo motor, and the driving gear 221 is preferably a long gear.

[0028] like Figure 1 , Figure 4 and Figure 6 As shown in FIG. 1 , when the sorting trolley 1 moves to the sorting position A1, the gear 1 21 on the sorting trolley 1 contacts one end of the driving gear 221 of the fixed driving gear mechanism 23, so that the gear 1 21 of the sorting trolley 1 is inserted into the driving gear 1 221 along the axial direction of the driving gear 221 of the fixed driving gear mechanism 23, so that the gear 1 21 and the driving gear 221 of the fixed driving gear mechanism 23 are in a meshing state, as shown in FIG. Figure 3 , Figure 4 As shown, during the movement of the sorting trolley 1 (as shown by arrow a in the figure), the driving gear 221 of the fixed driving gear mechanism 23 always drives the gear 1 21 on the sorting trolley 1 to rotate, thereby driving the trolley belt 15 to rotate (as shown by arrow b in the figure). When sorting is required at the A1 sorting location, the driving gear 221 of the fixed driving gear mechanism 23 is controlled to rotate, driving the gear 1 21 of the sorting trolley 1 to rotate, thereby driving the trolley belt 15 to rotate, and starting the sorting work. Figure 5As shown, the sorting trolley 1 continues to move, and the gear 121 on the sorting trolley 1 moves to the other end of the driving gear 221 of the fixed driving gear mechanism 23. As the sorting trolley 1 continues to move, the gear 121 on the sorting trolley 1 is separated from the other end of the driving gear 221 of the fixed driving gear mechanism 23. At this time, the sorting work at the A1 sorting location is completed; when the gear 121 is in meshing state with the driving gear 221 of the fixed driving gear mechanism 23 and there is no need to sort at the A1 sorting location, the fixed driving gear mechanism 23 is controlled to be in a stop state. As the sorting trolley 1 continues to move, the gear 121 on the sorting trolley 1 moves relatively along the driving gear 221 of the fixed driving gear mechanism 23 until the gear 121 on the sorting trolley 1 is separated from the other end of the driving gear 221 of the fixed driving gear mechanism 23.

[0029] 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 smoothly continue to move along the track when sorting is not required. In addition, the driving gear and the trolley belt are always in a separated state, avoiding direct contact between the driving gear and the trolley belt, and improving the service life of the trolley belt; thereby, 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.

[0030] Embodiment 2: Compared with Embodiment 1, the difference is that: Figure 7 As shown, the driving gear mechanism of the belt drive structure 2 is a movable driving gear mechanism 24, which is an up-and-down lifting mechanism, including a lifting mechanism 241, a second driving mechanism 242 arranged on the lifting mechanism 241, and a driving gear 221 arranged on the driving device. The lifting mechanism 241 can drive the second driving mechanism 242 and the driving gear 221 to move up and down together, and the second driving mechanism 242 can drive the driving gear 221 to rotate. In this embodiment, the lifting mechanism 241 can use a lifting cylinder, and the second driving mechanism 242 can use a servo motor. The tooth shape of the driving gear 221 matches the tooth shape of the gear 1 21 on the sorting trolley 1. The axial direction of the gear 1 21 is parallel to the axial direction of the driving gear 221.

[0031] like Figure 7As shown, when sorting is required at the A1 sorting location, the lifting mechanism 241 of the movable driving gear mechanism 24 is controlled to move, driving the driving mechanism 242 and the driving gear 221 to rise together, so that the driving gear 221 contacts the gear 1 21 on the sorting trolley 1 of the sorting trolley 1, so that the gear 1 21 on the sorting trolley 1 is inserted into the driving gear 221 along the axial direction of the driving gear 221 of the movable driving gear mechanism 24, so that the gear 1 21 is in a meshing state with the driving gear 221 of the movable driving gear mechanism 24, and then the driving mechanism 2 242 of the movable driving gear mechanism 24 is controlled to move, driving the driving gear 221 to rotate, thereby driving the trolley belt 15 of the sorting trolley 1 to rotate, and starting the sorting work.

[0032] When the sorting work at the sorting place is finished, the lifting mechanism 241 of the movable driving gear mechanism 24 is controlled to move again, driving the driving mechanism 242 and the driving gear 221 to descend back to the original position; when sorting is not needed at the sorting place, the lifting mechanism 241 of the movable driving gear mechanism 24 does not move, so that the driving gear 221 and the gear 1 21 on the sorting trolley 1 are in a state of being separated from each other, so as to facilitate the smooth passage of the sorting trolley 1.

[0033] Embodiment 3: Compared with embodiment 2, the difference is: Figure 8 As shown, the movable driving gear mechanism 24 is a swinging mechanism, which includes two swing arms 3, a cylinder 5, a frame 8 and a driving mechanism three (not shown in the figure). The driving mechanism three can adopt a servo motor. One end of the two swing arms 3 is hinged on the frame 8, and the driving gear 221 is connected to the shaft 9. The two ends of the shaft 9 are respectively rotatably connected to the other ends of the two swing arms 3 through bearings, so that the driving gear 221 is rotatably connected to the position between the two swing arms 3. The servo motor (not shown in the figure) is connected to one of the swing arms 3 and the output shaft of the driving motor is matched with the shaft 9 for transmission connection, so that under the drive of the driving motor, the driving gear 221 can be driven to rotate; the cylinder body of the cylinder 5 is hinged to the frame 8, and the piston rod 51 of the cylinder 5 is hinged to the other swing arm 3, so that under the action of the cylinder 5, the two swing arms 3 can be driven to swing back and forth.

[0034] When sorting is required at the A1 sorting location, the cylinder 5 of the movable drive gear mechanism 24 is controlled to move, and the two swing arms 3 are swung in the direction close to the trolley belt 15 of the sorting trolley 1, so that the drive gear 221 and the gear 1 21 on the sorting trolley 1 are in contact with each other, so that the drive gear 221 is inserted into the gear 1 21 on the sorting trolley 1 along the radial direction (Y direction) of the drive gear 221, so that the gear 1 and the drive gear 221 of the movable drive gear mechanism 24 are in a meshing state, and then the drive motor (not shown in the figure) of the movable drive gear mechanism 24 is controlled to move, driving the drive gear 221 to rotate, and then driving the gear 1 21 on the sorting trolley 1 to rotate, thereby driving the trolley belt 15 to rotate, and starting to sort. Sorting work; when the gear 1 on the sorting trolley 1 moves to the other end of the driving gear 221 of the movable driving gear mechanism 24, the gear 1 21 of the sorting trolley 1 is separated from the other end of the driving gear 221 of the movable driving gear mechanism 24, and then the cylinder 5 of the movable driving gear mechanism 24 is controlled to move again, and the two swing arms 3 are swung in the direction away from the trolley belt 15 of the sorting trolley 1, driving the driving gear 221 back to its original position; when the sorting trolley 1 moves to the A1 sorting position, at this time, when sorting is not required at the A1 sorting position, the cylinder 5 of the movable driving gear mechanism 24 does not move, so that the driving gear 221 and the trolley belt 15 of the sorting trolley 1 are in a state of separation from each other, which is convenient for the smooth passage of the sorting trolley 1.

[0035] Embodiment 4: 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. 9 As shown, belt conveyors 6 are provided at sorting locations A1 to A6, and one end of the trolley belt 15 of the sorting trolley 1 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 15 can be transferred to the transmission belt. When the sorted goods are fragile, the trolley belt 15 of the sorting trolley 1 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 during the transportation process of the trolley belt 15 of the sorting trolley 1 and causing damage, and the integrity of the sorted goods is ensured.

[0036] like Fig.10As shown, the basic structure of the belt conveyor 6 is the same as the basic structure of the sorting trolley 1, that is, it also includes a conveyor body 62, rollers three and four (not shown in the figure) rotatably connected to the conveyor body 62, and a transmission belt 61 is connected between the rollers three and four in a coordinated transmission manner.
