[0066] In addition, in the description of the present application, unless otherwise specified, the meaning of "multiple" and "multiple groups" is two or more.

[0067] Figure 1 shows a top view of an embodiment of a sorting system, in the following description, the direction reference basis in the drawing is taken as the direction reference basis in Figure 1, in Figure 1, the length direction of the translation track 1 is defined as the left-right direction, and the sorting mechanism 4 is located on the right side of the package supply mechanism 3; the width direction of the translation track 1 is defined as the front-rear direction, and the sorting lifting unit 8 is located on the front side of the translation track 1; the height direction of the rack 2 is defined as the up-down direction, wherein the direction perpendicular to the view paper and outward is the up direction.

[0068] As shown in Figures 1-3, the present application provides a sorting system, which comprises a translation track 1, and a package supply mechanism 3 and a plurality of sorting mechanisms 4 arranged along the extension direction of the translation track 1.

[0069] The package supply mechanism 3 comprises a package supply table 31 and a package supply assembly. The package supply assembly comprises a package supply trolley 33 and a package supply transmission unit 34 for driving the package supply trolley 33 to move along the translation track 1; the package supply table 31 is used to deliver articles to the package supply trolley 33.

[0070] The sorting mechanism 4 comprises a sorting assembly, the sorting assembly comprising a sorting trolley 5, a sorting transmission unit 9, a transfer unit 6 and a receiving unit 7. The sorting trolley 5 is driven by the sorting transmission unit 9 to move along the translation track 1; the transfer unit 6 and the receiving unit 7 are sequentially arranged along the extension direction of the translation track 1. As shown in FIG. 28, the receiving unit 7 comprises a row of dropping chutes 702 and a row of receiving frames 707 arranged sequentially from inside to outside along the width direction of the translation track 1. The specific number of dropping chutes included in each row of dropping chutes 702 and the specific number of receiving frames included in each row of receiving frames 707 can be set as required. Preferably, along the horizontal width direction of the translation track 1, one row of dropping chutes 702 and one row of receiving frames 707 are arranged on each side of the translation track 1.

[0071] The feeding trolley 33 can reciprocate along the translation track 1 between the feeding table 31 and the transfer unit 6 of the sorting mechanism 4 adjacent to the feeding mechanism 3; the sorting trolley 5 can reciprocate along the translation track 1 between the transfer units 6 of two adjacent sorting mechanisms 4, or between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4. The feeding trolley 33, the sorting trolley 5 and the transfer unit 6 all comprise a conveying belt that can convey articles along the horizontal width direction of the translation track 1.

[0072] In operation, the feeding trolley 33 can convey the articles received from the feeding table 31 to the transfer unit 6 adjacent thereto, and then the sorting trolley 5 in one or more sorting mechanisms 4 can convey the articles to the corresponding dropping chute through direct or relay transmission, and then the conveying belt of the sorting trolley 5 moves to make the articles enter the corresponding dropping chute 702, and the articles slide down along the dropping chute 702 and enter the receiving frame 707, thereby completing the delivery of the articles. The transfer unit 6 comprises one or more transfer trolleys, and the transfer trolleys have conveying belts that can move in the front-rear direction. When multiple transfer trolleys are arranged in each transfer unit 6, the multiple transfer trolleys are arranged at intervals along the extension direction of the translation track 1.

[0073] As can be seen from the above, the number of sorting mechanisms 4 can be adjusted according to the preset sorting amount, thereby increasing the number of receiving units 7 and realizing capacity expansion. Meanwhile, the articles provided by the feeding mechanism 3 can be relayed by the sorting trolleys 5 of multiple sorting mechanisms 4 and delivered to the receiving units 7 far away from the feeding mechanism 3, thereby breaking through the limitation of the moving stroke of the sorting trolley 5 by the single sorting transmission unit 9 and meeting the capacity expansion demand.

[0074] FIG. 1 shows an embodiment of the sorting system of the present application, wherein the translation track 1 is in the shape of a straight line, and multiple sorting mechanisms 4 are arranged on one side of the feeding mechanism 3 along the extension direction of the translation track 1. The working principle of the sorting system of the present application will be described in detail below in combination with FIG. 1:

[0075] The first sorting mechanism 41 comprises a first sorting assembly, which comprises a first sorting trolley 51, a first sorting driving unit 91, a first transfer unit 61 and a first receiving unit 71. The second sorting mechanism 42 comprises a second sorting assembly, which comprises a second sorting trolley 52, a second sorting driving unit 92, a second transfer unit 62 and a second receiving unit 72. The third sorting mechanism 43 comprises a third sorting assembly, which comprises a third sorting trolley 53, a third sorting driving unit 93, a third transfer unit 63 and a third receiving unit 73.

[0076] In each sorting mechanism 4, the transfer unit 6 is arranged at a side close to the feeding mechanism 3, and the receiving unit 7 is arranged at a side away from the feeding mechanism 3. Those skilled in the art can also adjust the relative positions of the transfer unit 6 and the receiving unit 7 according to needs, such as arranging the receiving unit 7 at a side close to the feeding mechanism 3.

[0077] After the feeding trolley 33 receives the articles from the feeding table 31, the articles are transported to the first transfer unit 61 of the first sorting mechanism 41 adjacent to the feeding mechanism 3.

[0078] When the articles need to be delivered to the first receiving unit 71, the first sorting trolley 51 is driven by the first sorting driving unit 91 to move to the first transfer unit 61 to receive the articles, and then moves to the first receiving unit 71 for delivery.

[0079] When the articles need to be delivered to the second receiving unit 72, the first sorting trolley 51 transports the articles from the first transfer unit 61 to the second transfer unit 62; the second sorting trolley 52 is driven by the second sorting driving unit 92 to move to the second transfer unit 62 to receive the articles, and then moves to the second receiving unit 72 for delivery.

[0080] When the articles need to be delivered to the third receiving unit 73, the first sorting trolley 51 transports the articles from the first transfer unit 61 to the second transfer unit 62, the second sorting trolley 52 transports the articles from the second transfer unit 62 to the third transfer unit 63, and the third sorting trolley 53 is driven by the third sorting driving unit 93 to move to the third transfer unit 63 to receive the articles, and then moves to the third receiving unit 73 for delivery.

[0081] The skilled in the art can increase or decrease the number of sorting mechanisms 4 based on the embodiment one, the working principle of the relay transmission between more number of sorting mechanisms 4 is analogized. Each feeding mechanism 3 has one or more feeding tables 31, which can be selected by the skilled in the art as needed. In the embodiment one, the feeding mechanism 3 is arranged at the end of the translation track 1, which includes one feeding table 31 arranged at the front side or the rear side of the end of the translation track 1, or includes two feeding tables 31 arranged symmetrically about the front and rear of the end of the translation track 1. Correspondingly, the feeding drive unit 34 is used to drive one feeding trolley 33 to reciprocate between the feeding table 31 and the first transfer unit 61.

[0082] Fig. 2 and Fig. 3 show the embodiment two of the sorting system of the present application, which is different from the embodiment one in that a plurality of sorting mechanisms 4 are arranged on the left and right sides of the feeding mechanism 3 along the extension direction of the translation track 1, and the feeding mechanism 3 is arranged at the non-end of the translation track 1, preferably at the middle of the translation track 1. The feeding mechanism 3 includes four feeding tables 31, which are arranged symmetrically about the translation track 1 along the horizontal width direction of the translation track 1. Correspondingly, the feeding drive unit 34 is used to drive two feeding trolleys 33 to reciprocate between the feeding table 31 and the two adjacent transfer units 6 on the left and right. The number of sorting mechanisms 4 on the left and right sides of the feeding mechanism 3 can be the same or different.

[0083] Fig. 4 and Fig. 5 show the embodiment three of the sorting system of the present application, in which the translation track is in the shape of a broken line, including a plurality of connected segments, and the plurality of connected segments are arranged in the shape of a arch, and the included angle between the adjacent two connected segments is 90°. The feeding mechanism 3 is arranged at one end of the translation track, and each connected segment is correspondingly provided with one sorting mechanism 4, and the transfer unit in each sorting mechanism 4 is arranged at one end of the connected segment, which is convenient for docking with the feeding mechanism 3 or the adjacent sorting mechanism 4.

[0084] Fig. 6 shows the embodiment four of the sorting system of the present application, in which the translation track is also in the shape of a broken line, including a plurality of connected segments, and the included angle between the adjacent two connected segments is 90°. The difference between it and the embodiment three is that the plurality of connected segments are arranged in the shape of a ladder.

[0085] In addition to the above-mentioned embodiment three and embodiment four, the plurality of connected segments can also be arranged in the shape of L.

[0086] Fig. 6 shows the embodiment five of the sorting system of the present application, in which the translation track is in the shape of T, including a first branch extending in the front and rear direction and two second branches extending in the left and right direction, and the feeding mechanism 3 is arranged at one end of the first branch or the second branch.

[0087] Figure 7 shows a sixth embodiment of the sorting system of the present invention. In this sixth embodiment, the translation track is maze-shaped, including a first branch extending in the front-back direction and multiple second branches extending in different horizontal directions. The second branches are all connected to the first branch, and the package feeding mechanism 3 is located at one end of the first branch.

[0088] Further, as shown in Figure 1, the package feeding transmission unit 34 includes a package feeding transmission component connected to the package feeding carriage 33; the sorting transmission unit 9 includes a sorting transmission component connected to the sorting carriage 5. The package feeding transmission component and the sorting transmission component can be ball screws driven by a motor, with their sliders connected to the package feeding carriage 33 / sorting carriage 5; or they can be racks, ropes, belts, or chains disposed between a pair of driving wheels and driven wheels.

[0089] In Embodiments 1, 3 to 5, the package feeding drive extends from the location of the package feeding platform 31 to the adjacent transfer unit 6; in Embodiment 2, the package feeding drive extends from the transfer unit 6 adjacent to its left to the transfer unit 6 adjacent to its right. In the adjacent package feeding mechanism 3 and sorting mechanism 4, the package feeding drive and the sorting drive have an overlapping section at the transfer unit 6, so the package feeding trolley 33 can reciprocate along the translation track 1 between the package feeding platform 31 and the transfer unit 6 of the adjacent sorting mechanism 4.

[0090] The sorting drive unit located at the non-end position of the translation track 1 extends from the transfer unit 6 of its respective sorting mechanism 4 to the transfer unit 6 of the adjacent sorting mechanism 4, which is relatively far from the feeding mechanism 3. That is, in two adjacent sorting mechanisms 4, the two sorting drive units have overlapping sections at the transfer unit 6, which is far from the feeding mechanism 3. Therefore, the sorting trolley 5 located at the non-end position of the translation track 1 can reciprocate along the translation track 1 between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4 to complete one item delivery, and can also reciprocate along the translation track 1 between the transfer units 6 of two adjacent sorting mechanisms 4 to achieve relay transmission of items. The sorting drive unit located at the end position of the translation track 1 extends from the transfer unit 6 of its respective sorting mechanism 4 to the receiving unit 7 of the same sorting mechanism 4. Therefore, the sorting trolley 5 located at the end position of the translation track 1 can reciprocate between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4.

[0091] As can be seen from Embodiments 1 to 6, the sorting system provided by the present invention can achieve unlimited expansion on the horizontal plane by increasing the number of sorting mechanisms 4 set along the translation track 1, and complete single-layer package feeding and single-layer sorting.

[0092] Furthermore, to improve the sorting efficiency of the sorting system and achieve single-layer feeding and multi-layer sorting functions, as shown in Figures 1-4, the sorting system of the present invention also includes a fixedly installed frame 2, with N sets of translation tracks 1 spaced apart along the height direction of the frame 2. Each set of translation tracks 1 includes one translation track 1 or two parallel translation tracks 1. Compared to moving along one translation track 1, the movement of the sorting trolley 5 along two translation tracks 1 simultaneously is undoubtedly more stable. The N sets of translation tracks 1 divide the frame 2 into N layers. At the same time, the feeding mechanism 3 includes N feeding components spaced apart along the height direction of the frame 2, and the sorting mechanism 4 includes N sorting components spaced apart along the height direction of the frame 2, where N is an integer greater than or equal to 2. There is a one-to-one correspondence between the N feeding components, N sorting components and N sets of translation tracks 1. That is, the feeding mechanism 3 has a feeding component on each layer and the sorting mechanism 4 has a sorting component on each layer, ensuring that the items can be directly or relayed along a set of translation tracks 1 on each layer.

[0093] The feeding mechanism 3 also includes a feeding lifting unit 32 disposed between the feeding platform 31 and the frame 2. The feeding lifting unit 32 includes a lifting feeding trolley, which is used to transport multiple items provided by the feeding platform 31 to feeding trolleys 33 of different feeding components. Each sorting mechanism 4 also includes a sorting lifting unit 8. The sorting lifting unit 8 and the transfer unit 6 are disposed on different sides of the translation track 1 and the frame 2 along the horizontal width direction of the translation track 1. That is, the corresponding positions of the sorting lifting unit 8 and the transfer unit 6 on the translation track 1 are the same. The conveyor belt of the sorting trolley 5 or the feeding trolley 33 can be moved in different directions to dock with the sorting lifting unit 8 or the transfer unit 6. The sorting lifting unit 8 includes a lifting sorting trolley and a receiving part 800 disposed on the outside of the sorting lifting trolley (here, "outside" refers to the side away from the sorting trolley 5). The sorting lifting trolley is used to transport items between sorting trolleys 5 at different heights; the receiving section 800 is used to receive items that cannot be delivered due to malfunction of the sorting components. Specifically, both the package feeding lifting trolley and the sorting lifting trolley have conveyor belts that can move in the front-to-back direction. The receiving section 800 is fixedly installed at the bottom of the sorting lifting unit 8, and includes one or more receiving baskets arranged side by side in the left-to-right direction.

[0094] The functions of the package feeding lifting unit 32 and the sorting lifting unit 8 will be explained below with reference to the embodiments:

[0095] In Example 1, N=5, that is, 5 sets of translation tracks 1 are arranged at intervals along the height direction of the frame 2, dividing the frame 2 into 5 layers.

[0096] When the sorting system is working normally, the feeding lifting trolley can transport the items provided by the feeding table 31 to the feeding trolley 33 on any layer. Then the items are transferred between the transfer unit 6 and the sorting trolley 5 on the same layer as the feeding trolley 33, and finally delivered to the receiving unit 7 on the same layer.

[0097] When the sorting component on the third layer of the first sorting mechanism 41 malfunctions, but the items need to be transported to the second receiving unit 72 on the third layer of the second sorting mechanism 42, the sorting system operates as follows: The feeding lifting trolley transports the items provided by the feeding table 31 to the feeding trolley 33 on the third layer. The feeding trolley 33 moves to the first sorting lifting unit 81 of the first sorting mechanism 41 and transports the items to the first sorting lifting trolley in the first sorting lifting unit 81. The first sorting lifting trolley transports the items to the first sorting trolley 51 on the second layer. Then, the first sorting trolley 51 moves to the second sorting lifting unit 82 of the second sorting mechanism 42. The second sorting lifting trolley in the second sorting lifting unit 82 transports the items to the second sorting trolley 52 on the third layer. The second sorting trolley 52 delivers the items to the second receiving unit 72 on the third layer.

[0098] When the sorting component in the third layer of the first sorting mechanism 41 malfunctions, but it is necessary to transport the items to the first receiving unit 71 in the third layer, the sorting system works as follows: the supply lifting trolley transports the items provided by the supply table 31 to the supply trolley 33 in the third layer, the supply trolley 33 moves to the first sorting lifting unit 81 and transports the items to the first sorting lifting trolley, the first sorting lifting trolley descends to the vicinity of the receiving section 800 and transports the items to the receiving section 800.

[0099] As can be seen from the above, compared to a sorting system with a single-layer structure that can only expand infinitely in the horizontal plane, a sorting system with a multi-layer structure can expand vertically to increase the sorting capacity, and also allows the feeding carts 33 and sorting carts 5 on different layers to work simultaneously, realizing the function of single-layer feeding and multi-layer sorting, which greatly improves the sorting efficiency of items. At the same time, by setting a sorting lifting unit 8 in each sorting mechanism 4, this invention can both detour around the faulty layer during relay transmission and accommodate items that cannot be delivered, thereby avoiding the failure of a single sorting component from affecting the normal operation of the entire sorting system, reducing the maintenance frequency of the sorting system, and further ensuring the efficient operation of the sorting system.

[0100] The specific embodiments of the above-mentioned components will be described in detail below with reference to the accompanying drawings:

[0101] Packing table

[0102] The package feeding station 31 has the following two embodiments: Embodiment 1 as shown in Figures 9-13, and Embodiment 2 as shown in Figures 14-16.

[0103] As shown in Figure 9, Embodiment 1 of the bag feeding platform 31 includes a bag feeding frame 310 with a bag feeding area 3101, and an array of conveying components 35 all assembled in the bag feeding area 3101. The conveying direction of the conveying components 35 is the same as the conveying direction (i.e., the front-to-back direction) of the bag feeding platform 31. The array of conveying components 35 are arranged front-to-back along their conveying direction. The number of conveying components 35 assembled in a single bag feeding area 3101 is determined according to actual needs, and can be two, three, or more sets; a single bag feeding area 3101 is equipped with two sets of conveying components 35.

[0104] As shown in Figure 10-13, the bag feeding machine frame 310 has frame side plates 3102 fixed on both the left and right sides of the bag feeding area 3101. The frame side plates 3102 are part of the bag feeding machine frame 310. Each conveying assembly 35 includes a conveying drive source 351, a pair of support rollers 352 arranged side by side along its conveying direction, and a conveyor belt 311 connected to the outer periphery of the pair of support rollers 352. The pair of support rollers 352 are arranged at the same height, so that the conveyor belt 311 has a conveying plane connected to the upper end of the pair of support rollers 352. The left and right ends of the support rollers 352 are rotatably supported in the frame side plates 3102 of the packaging frame 310 and are connected to the conveying drive source 351. A triangular area 312 is formed between two adjacent conveying assemblies 35. The support rollers 352 are small-diameter rollers with a diameter of no more than 40 mm. That is, the support rollers 352 are rollers with unconventional outer diameters, but rather small-diameter rollers with outer diameters much smaller than unconventional outer diameters are used.

[0105] In the bag-feeding platform 31, when the conveyor drive source 351 is activated, a pair of support rollers 352 rotate, and simultaneously, the conveyor belt 311 rotates. Sorting personnel place multiple items to be sorted onto the conveyor plane of the conveyor belt 311 of the last set of conveyor components 35 in the bag-feeding platform 31. The conveyor belt 311 of this set of conveyor components 35 then conveys the items forward. In particular, the support rollers 352 in this application are small-diameter rollers with a diameter not exceeding 40 mm. This significantly reduces the size of the triangular-like region 312 formed between two adjacent sets of conveyor components 35, making the connection between the two sets of conveyor components 35 smoother. This effectively prevents small items from getting stuck in the triangular-like region 312, ensuring that items conveyed forward by the latter set of conveyor components 35 can smoothly transition to the former set of conveyor components 35, greatly reducing the probability of dropped items, and ultimately ensuring the reliability and accuracy of the sorted items. Finally, the sorted items are conveyed forward by the conveyor belt 311 of the multiple conveying components 35 and then transported to the front end of the packing station 31; thereafter, the packing trolley 33 receives the sorted items. Therefore, the rear end of the packing station 31 is the inlet end of its sorted items, and the front end of the packing station 31 is the outlet end of its sorted items.

[0106] In addition, each of the multiple conveying components 35 adopts an independent conveying drive source 351, so that the conveying speed of the conveyor belt 311 of each conveying component 35 is independently controlled. This allows for better control of the buffering of sorted items on the multiple conveying components 35, avoiding excessive accumulation of sorted items at the front end of the feeding table 31, thereby improving equipment efficiency.

[0107] Preferably, the diameter of the support roller 352 is 28-32 mm, which can effectively prevent small sorted items from getting stuck in the triangular area 312, and also ensure good support performance for the conveyor belt 311.

[0108] Furthermore, since the support roller 352 adopts a small-diameter roller structure, the contact area between the support roller 352 and the conveyor belt 311 will inevitably be reduced, which will also inevitably reduce the friction between the support roller 352 and the conveyor belt 311. If the structure of using the conveyor drive source 351 to drive the support roller 352 to rotate and drive the conveyor belt 311 to rotate is adopted, there will be a defect that the rotation speed of the conveyor belt 311 cannot reach the required speed. Therefore, the preferred drive structure of the conveyor drive source 351 driving the conveyor belt 311 to rotate in the first embodiment of the packaging platform 31 is: the conveyor drive source 351 is a motor, and each group of conveying components 35 also includes a transmission roller 354, a first pulley 355 fixed on the motor shaft of the conveyor drive source 351, a second pulley 356 fixed on the transmission roller 354, and a synchronous belt 357 connecting the first pulley 355 and the second pulley 356. The transmission roller 354 and the support roller The left and right ends of the drive roller 354 are rotatably supported in the frame side plate 3102 of the packaging machine frame 310. The drive roller 354 is a roller with an unconventional outer diameter. The diameter of the drive roller 354 is larger than the diameter of the support roller 352. Preferably, the diameter of the drive roller 354 is 3-5 times larger than the diameter of the support roller 352. The drive roller 354 is in contact with the inner circumferential surface of the conveyor belt 311 and is distributed below the pair of support rollers 352. Thus, the conveying drive source 351 drives the transmission roller 354 to rotate through the first pulley 355, the second pulley 356 and the synchronous belt 357. The transmission roller 354 has a large contact area and a large frictional force with the conveyor belt 311. The transmission roller 354 drives the conveyor belt 311 to rotate, which not only improves the reliability of the rotational motion of the conveyor belt 311 and ensures that it accurately conveys the sorted items forward, but also ensures that the speed of the conveyor belt 311 meets the design requirements.

[0109] Furthermore, as shown in Figure 12, a motor mounting area 358 is formed on the outer periphery of the conveyor belt 311 between one of the pair of support rollers 352 and the transmission roller 354. The conveying drive source 351 is located in the motor mounting area 358 and fixed to the frame side plate 3102 of the bag supply frame 310, which facilitates the installation of the conveying drive source 351 and makes the overall structure more compact, reducing the overall space occupied by the bag supply platform 31.

[0110] Further, as shown in Figures 10-12, each conveying assembly 35 also includes a tension adjusting roller 359 and a tension adjusting assembly. The tension adjusting roller 359 is disposed in the motor mounting area 358. The tension adjusting roller is parallel to the drive roller 354. The tension adjusting roller 359 includes a roller shaft portion 3591 and a tensioning cylinder portion 3592 rotatably mounted on the roller shaft portion 3591. The tensioning cylinder portion 3592 contacts and engages with the outer peripheral surface of the conveyor belt 311. The roller shaft portion 3591 is mounted on the packing frame 310 and can be moved back and forth via the tension adjusting assembly. Thus, by adjusting the back and forth position of the roller shaft portion 3591 via the tension adjusting assembly, the back and forth position of the tension adjusting roller 359 is adjusted, thereby adjusting the tension of the conveyor belt 311. Preferably, the tension adjustment assembly can adopt a bolt and nut structure: the tension adjustment assembly includes an adjustment seat 3510 fixed to the packing machine frame 310, an adjustment groove 3511 opened in the packing machine frame 310 and extending back and forth, an adjustment bolt extending back and forth, and a locking nut connected to the adjustment bolt. The adjustment bolt and the locking nut are not shown in the figure. The roller shaft part 3591 is movably inserted into the adjustment groove 3511. The adjustment bolt is inserted into the roller shaft part 3591 and the adjustment seat 3510. The locking nut abuts against the outer periphery of the roller shaft part 3591.

[0111] Furthermore, the outer circumferential surface of the conveyor belt 311 is provided with at least one circumferentially extending limiting rib 353; when there are multiple limiting ribs 353, the multiple limiting ribs 353 are arranged side by side in a direction perpendicular to the conveying direction of the conveying assembly 35. The limiting ribs 353 limit the sorted items being conveyed forward on the conveyor belt 311 in the left and right directions, improving the accuracy of forward conveying of the sorted items. The number of limiting ribs 353 on each conveyor belt 311 is determined according to actual needs. In this embodiment, there are two limiting ribs 353, one on the left and one on the right.

[0112] Furthermore, as shown in Figure 9, the bag feeding frame 310 has several bag feeding areas 3101, which are arranged side by side along a direction perpendicular to the conveying direction of the conveying components 35. Each bag feeding area 3101 is equipped with an array of conveying components 35. In this first embodiment, the bag feeding frame 310 has two bag feeding areas 3101, one on the left and one on the right, and each bag feeding area 3101 is equipped with two sets of conveying components 35. This arrangement can improve the bag feeding efficiency of the sorted items, and ultimately improve the sorting efficiency of the sorting system.

[0113] Furthermore, as shown in Figure 13, along the conveying direction of the sorted items conveyed forward by the conveying assembly 35, multiple sets of conveying assemblies 35 are distributed in a stepped manner from back to front and from high to low, that is, the conveying assemblies 35 distributed on the rear side are higher than the conveying assemblies 35 distributed on the front side. In this way, the staggered structure of the two adjacent sets of conveying assemblies 35 can better reduce the gap between the two sets of conveying assemblies 35, making the triangular area 312 smaller and better preventing items from falling. At the same time, using multiple sets of conveying assemblies 35 at the front and rear can prevent the formation of a groove in the middle of the conveyor belt 311, thereby avoiding the undesirable phenomenon of light sorted items jumping on the conveyor belt 311 and ensuring the reliability of feeding.

[0114] As shown in Figures 14 and 15, Embodiment 2 of the packing station 31 includes a packing frame 310 and multiple sets of feeding belt conveyor assemblies 36, all mounted on the packing frame 310. Each feeding belt conveyor assembly 36 includes a feeding drive source 361 mounted on the packing frame 310, a drive roller 362 and a driven roller 363 rotatably mounted on the packing frame 310, and a feeding conveyor belt 364 connected to the outer periphery of the drive roller 362 and the driven roller 363. The feeding drive source 361 is drive-connected to the drive roller 362, and the feeding drive sources 361 in the multiple sets of feeding belt conveyor assemblies 36 are independent of each other. In each feeding belt conveyor assembly 36, the drive roller 362 and the driven roller 363 extend horizontally and are arranged side by side. The sorted items are conveyed forward along the feeding conveyor belt 364. Multiple sets of feeding belt conveyor assemblies 36 are connected sequentially from back to front and are distributed in a stepped manner from high to low. The feeding belt conveyor assembly 36 distributed at the back is the highest, and the feeding belt conveyor assembly 36 distributed at the front is the lowest. Furthermore, two adjacent sets of feeding belt conveyor assemblies 36 are arranged close together.

[0115] Each set of feeding belt conveyor assemblies 36 is driven by an independent feeding drive source 361, allowing independent control of the conveying speed of the feeding conveyor belt 364 in each set. This enables better control of the buffering of sorted items on multiple sets of feeding belt conveyor assemblies 36, preventing excessive accumulation of sorted items at the front of the sorting and feeding mechanism, thereby improving equipment efficiency. Furthermore, in this embodiment, the multiple sets of feeding belt conveyor assemblies 36 are arranged in a stepped distribution, with the height of each set decreasing sequentially from back to front. This means that adjacent sets of feeding belt conveyor assemblies 36 are staggered vertically, allowing them to be arranged close together and reducing the gap between adjacent sets, thus preventing items from falling off. Furthermore, the multiple sets of feeding belt conveyor assemblies 36 are arranged in a stepped distribution structure from high to low, which can prevent the formation of grooves in the middle part of the feeding conveyor belt 364, thereby avoiding the adverse phenomenon of light sorted items jumping on the feeding conveyor belt 364 and ensuring feeding reliability.

[0116] Preferably, the number of feeding belt conveyor assemblies 36 is determined according to actual needs, and can be 2, 3, 4 or more; in the embodiment shown in Figure 14, there are 3 sets of feeding belt conveyor assemblies 36.

[0117] Furthermore, the preferred structure of the bag supply frame 310 is as shown in Figure 14, which further includes a pair of frame side plates 3102 fixed to the upper end of the bag supply frame 310. The pair of frame side plates 3102 are distributed opposite each other on the left and right sides of the feeding conveyor belt 364 of the multiple sets of feeding belt conveyor assemblies 36, in a direction perpendicular to the conveying direction of the feeding conveyor belt 364. At the same time, the frame side plates 3102 are also higher than the feeding conveyor belt 364 of the multiple sets of feeding belt conveyor assemblies 36. By setting the frame side plates 3102, it is possible to prevent the sorted items on the feeding conveyor belt 364 from falling off from the left and right sides, thereby improving the reliability of forward conveying of the sorted items.

[0118] Furthermore, as shown in Figure 14, each set of feeding belt conveyor assemblies 36 also includes a detection unit installed on the bag supply frame 310. The detection unit is used to detect whether there are any objects passing on the feeding conveyor belt 364 of that set of feeding belt conveyor assemblies 36. In this way, it is possible to detect the forward passage of the first sorted object and the last sorted object on the sorting feeding mechanism for sorting start control and sorting stop control; at the same time, it is also possible to detect the length of the sorted objects conveyed on the sorting feeding mechanism. When the length of the sorted object exceeds the threshold, it is judged as misplacement, and an alarm will be triggered, thereby improving operational safety.

[0119] Preferably, as shown in FIG14, the detection unit includes a grating sensor 368 fixed to the outside of the frame side plate 3102 and a detection opening 3103 formed in the frame side plate 3102, the detection opening 3103 allowing the grating sensor 368 to be exposed. Furthermore, in each set of feeding belt conveyor assemblies 36, the bottom of the detection opening 3103 is flush with the top of the feeding conveyor belt 364, enabling more reliable detection of whether an object is passing on the feeding conveyor belt 364.

[0120] Furthermore, as shown in Figure 14, the sorted items are conveyed forward along the feeding conveyor belt 364. The head end (i.e. front end) of the frame side plate 3102 is provided with a material picking avoidance area 3104 to avoid interference between the frame side plate 3102 and the material picking of the bag feeding trolley 33 or the bag feeding lifting unit 32.

[0121] Further, as shown in Figure 14, the feeding drive source 361 is a motor and is staggered with the drive roller 362. Each feeding belt conveyor assembly 36 also includes a transmission unit, and the feeding drive source 361 is connected to the drive roller 362 through the transmission unit. The staggered distribution structure of the feeding drive source 361 and the drive roller 362 reduces the size of the sorting feeding mechanism in the left-right direction, facilitating its installation in the sorting system. Preferably, the transmission unit includes a drive pulley 365 fixed on the motor shaft of the feeding drive source 361, a driven pulley 366 fixed at the end of the drive roller 362, and a transmission belt 367 connecting the outer periphery of the drive pulley 365 and the driven pulley 366.

[0122] Furthermore, as shown in Figures 14 and 15, each set of feeding belt conveyor assembly 36 also includes an adjustment unit. The adjustment unit includes an adjustment slot 3105 opened in the bag feeding frame 310, an adjustment plate 369 fixed to the bag feeding frame 310, and an adjustment screw 3610 rotatably inserted in the adjustment plate 369. The adjustment slot 3105 and the adjustment screw 3610 extend straight back and forth along the conveying direction of the feeding conveyor belt 364. The driven roller 363 includes a roller shaft 3631 and a roller rotatably installed on the outer periphery of the roller shaft 3631. The two ends of the roller shaft 3631 are engaged in the adjustment slot 3105 and threadedly connected to the adjustment screw 3610. By rotating the adjusting screw 3610, the front and rear positions of the roller shaft 3631 of the driven roller 363 in the adjusting groove 3105 can be adjusted, thereby adjusting the front and rear positions of the driven roller 363, and thus adjusting the tension of the feeding conveyor belt 364 in the feeding belt conveyor assembly 36, so that it can more reliably transport the sorted items forward.

[0123] Sorting organization

[0124] As shown in Figures 1, 16, and 17, two adjacent sorting mechanisms 4 are designated as the first sorting mechanism 41 and the second sorting mechanism 42. The first sorting mechanism 41 includes a first sorting assembly, which comprises a first sorting trolley 51, a first sorting transmission unit 91, a first transfer unit 61, and a first receiving unit 71. The first sorting trolley 51 is movably mounted on the translation track 1 via the first sorting transmission unit 91. The second sorting assembly includes a second sorting trolley 52, a second sorting transmission unit 92, a second transfer unit 62, and a second receiving unit 72. The second sorting trolley 52 is movably mounted on the translation track 1 via the second sorting transmission unit 92.

[0125] Along the extension direction of the translation track 1, at the non-end position of the translation track 1, there are picking stations for the first sorting trolley 51 and the second sorting trolley 52 to pick up items. The picking stations are distributed along the travel distance of the first sorting trolley 51 and the second sorting trolley 52 along the translation track 1, so that the travel distance of the first sorting trolley 51 and the second sorting trolley 52 overlaps at the picking station. The picking station is equipped with a transfer unit 6 and a sorting lifting unit 8. That is, in two adjacent sorting mechanisms 4, the two sorting transmission components overlap at the transfer unit 6, which is farther away from the packaging mechanism 3. Therefore, the sorting trolley 5 at the non-end position of the translation track 1 can reciprocate along the translation track 1 between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4 to complete one item delivery, and can also reciprocate along the translation track 1 between the transfer units 6 of two adjacent sorting mechanisms 4 to realize the relay transfer of items.

[0126] The following are four embodiments of the sorting mechanism of the present invention:

[0127] Sorting Mechanism Embodiment 1: To ensure the smooth movement of the sorting trolleys and prevent them from tilting or swaying during movement, the translation track 1 in Embodiment 1 is a horizontal track, and two tracks are provided: a first translation track 11 and a second translation track 12. The first translation track 11 and the second translation track 12 are parallel to each other and are arranged opposite each other along their horizontal width direction (i.e., the front-to-back direction). The first sorting transmission unit 91 and the second sorting transmission unit 92 are arranged between the two translation tracks 1. Those skilled in the art can choose different shapes of the translation tracks 1 as needed. The translation track 1 can be a straight track extending in the left-to-right direction or a curved track. Along the horizontal width direction of the translation track 1, the front side of the first sorting trolley 51 and the front side of the second sorting trolley 52 are movably mounted on the second translation track 12, and the rear side of the first sorting trolley 51 and the rear side of the second sorting trolley 52 are movably mounted on the first translation track 11. Because the first sorting trolley 51 and the second sorting trolley 52 are limited and supported by the first translation track 11 at their rear, and the first sorting trolley 51 and the second sorting trolley 52 are limited and supported by the second translation track 12 at their front, they will not tip over to the front or rear during movement, and can remain stable during long-term operation. The first sorting drive component 911 and the second sorting drive component 921 are disposed between the two translation tracks 1, both located in front of the first translation track 11 and behind the second translation track 12. Along the horizontal width direction of the translation track 1, the first sorting drive unit 91 includes two first sorting drive components 911 symmetrically distributed relative to and connected to the first sorting trolley 51, and the second sorting drive unit 92 includes two second sorting drive components 921 symmetrically distributed relative to and connected to the second sorting trolley 52. ​​The arrangement order of the second sorting drive components 921 and the two first sorting drive components 911 between the two translation tracks 1 can take various forms. One configuration involves two second sorting drive components 921 positioned between two first sorting drive components 911. Another configuration involves two first sorting drive components 911 and two second sorting drive components 921 staggered along the width of the translation track 1. In this configuration of Embodiment 1, the two sorting drive units do not interfere with each other during installation and use, and allow two sorting trolleys 5 to move simultaneously along the same translation track 1, effectively improving sorting efficiency. Simultaneously, it provides stable support for the sorting trolleys 5, preventing the connection points between the sorting drive components and the sorting trolleys 5 from being too concentrated at the ends of the sorting trolleys 5, thus avoiding downward tilting of the ends of the sorting trolleys 5 not connected to the sorting drive components.

[0128] Sorting transmission units come in various forms.

[0129] The first type of sorting transmission unit includes a translation drive wheel, a translation driven wheel, and a sorting transmission component. The translation driven wheel and the translation drive wheel can be pulleys, gears, or sprockets, while the sorting transmission component can be a rack, rope, belt, or chain, or other transmission component that can convert the rotational motion of the wheel into translational motion.

[0130] Correspondingly, the first sorting transmission unit 91 includes two first translation drive wheels, two first translation driven wheels, and two first sorting transmission components 911. The two translation drive wheels are arranged one after the other on the same first synchronous shaft 9121 extending along the horizontal width of the translation track 1. At the same time, the two first translation driven wheels are arranged opposite each other, so that the two first sorting transmission components 911 are arranged parallel to each other. The first sorting trolley 51 is connected between the two first sorting transmission components 911, and the two first sorting transmission components 911 are symmetrically distributed about the first sorting trolley 51. One end of the first synchronous shaft 9121 is connected to the first sorting drive source 912 and rotates under the drive of the first sorting drive source 912, driving the first sorting trolley 51 connected to the first sorting transmission component 911 to move along the translation track 1. Similarly, the second sorting transmission unit 92 includes two second translation drive wheels, two second translation driven wheels, and two second sorting transmission components 921. The two second translation drive wheels are arranged one after the other on the same second synchronous shaft 9221, while the two second translation driven wheels are arranged opposite each other, so that the two second sorting transmission components 921 are arranged parallel to each other. The second sorting trolley 52 is connected between the two second sorting transmission components 921, and the two second sorting transmission components 921 are symmetrically distributed about the second sorting trolley 52. ​​One end of the second synchronous shaft 9221 is connected to the second sorting drive source 922 and rotates under the drive of the second sorting drive source 922, driving the second sorting trolley 52 connected to the second sorting transmission component 921 to move along the translation track 1.

[0131] The second type of sorting transmission unit is a ball screw, and the sorting transmission component is a screw extending parallel to the translation track 1. The screw is connected to the sorting trolley through a nut.

[0132] Correspondingly, the first sorting drive source 912 drives the first sorting transmission component 911 to rotate, which in turn drives the first sorting trolley 51 to move along the translation track 1 via the first nut. The second sorting drive source 922 drives the second sorting transmission component 921 to rotate, which in turn drives the second sorting trolley 52 to move along the translation track 1 via the second nut.

[0133] The difference between the second embodiment of the sorting mechanism and the first embodiment is that, along the horizontal width direction of the translation track 1, the first sorting transmission unit 91 includes two first sorting transmission components 911 symmetrically distributed relative to and connected to the first sorting trolley 51, and the second sorting transmission unit 92 includes a second sorting transmission component 921 centrally distributed relative to and connected to the second sorting trolley 52. ​​The two first sorting transmission components 911 and the second sorting transmission component 921 are all located between the two translation tracks 1, and the second sorting transmission component 921 is arranged between the two first sorting transmission components 911.

[0134] The difference between the third embodiment of the sorting mechanism and the first embodiment of the sorting mechanism is that the first sorting transmission unit 91 includes a first sorting transmission component 911 connected to the first sorting trolley 51, and the second sorting transmission unit 92 includes a second sorting transmission component 921 connected to the second sorting trolley 52. ​​The first sorting transmission component 911 and the second sorting transmission component 921 are both located between two translation tracks 1, and the first sorting transmission component 911 and the second sorting transmission component 921 are spaced apart along the horizontal width direction of the translation track 1.

[0135] As shown in Figure 18, the difference between Embodiment 4 and Embodiment 1 of the sorting mechanism is that Embodiment 4 only has one translation track 1, which is a horizontal track. The first sorting trolley 51 and the second sorting trolley 52 are movably mounted on the translation track 1. The first sorting transmission unit includes a first sorting transmission component 911 connected to the first sorting trolley 51, and the second sorting transmission unit includes a second sorting transmission component connected to the second sorting trolley. The first sorting transmission component 911 and the second sorting transmission component are arranged on the same side or different sides of the translation track 1 along the horizontal width direction. When the first sorting transmission component 911 and the second sorting transmission component are arranged on the same side of the translation track 1, they are spaced apart and do not interfere with each other.

[0136] As shown in Figure 19, the first sorting trolley 51 in embodiments one to four of the above-mentioned sorting mechanism includes a trolley support 500, on which two rollers are mounted, and a conveyor belt 502 is positioned between the two rollers. The rollers rotate under the drive of a rotary drive source, or the rollers are electric rollers. When the rollers rotate, they can drive the conveyor belt 502 to move forward or backward.

[0137] Furthermore, in the above embodiments one to three, along the horizontal width direction of the translation track 1, a plurality of translation wheels 505 are provided on both the front and rear sides of the first sorting trolley 51. The translation wheels 505 are set in the grooves on the translation track 1 and can travel along the translation track 1, so that the first sorting trolley 51 can be movably installed on the two translation tracks 1.

[0138] The structure of the second sorting cart 52 is exactly the same as that of the first sorting cart 51, and will not be described again here.

[0139] The arrangement of the package feeding drive unit 34 is the same as that of the sorting drive unit 9. The arrangement between adjacent package feeding drive units 34 and sorting drive units 9 is the same as that between the first sorting drive unit 91 and the second sorting drive unit 92, and the package feeding drive component and the sorting drive component have an overlapping section at the transfer unit 6 of the sorting drive unit 9.

[0140] Sorting cart

[0141] The sorting cart has the following two embodiments: Embodiment 1 as shown in Figures 19-20, and Embodiment 2 as shown in Figures 21-25.

[0142] In Embodiment 1 of the sorting cart 5: As shown in Figure 19, the sorting cart 5 includes a support frame, on which one or more conveying sections are mounted. Each conveying section includes multiple rollers 501 rotatably mounted on the support frame and a conveyor belt 502 connected between the multiple rollers 501. One or more rollers 501 in each conveying section are electric rollers or connected to a rotary drive source. When the rollers 501 rotate, the conveyor belt 502 moves forward or backward. When multiple conveying sections are provided on the support frame, the multiple conveying sections are spaced apart on the support frame in a left-right direction. Sorting personnel can place items of different sizes or types on different conveyor belts 502 of the same sorting cart 5 as needed, increasing the number of items transported by each sorting cart 5 in a single trip, and controlling the operation of different conveying sections when the sorting cart 5 arrives at the designated receiving unit 7 to complete the delivery, thereby improving sorting efficiency. The support also includes two baffles 506, which extend along the conveying direction (i.e., the front-to-back direction) of the conveyor belt 502. The two baffles 506 are arranged on the left and right sides of the conveyor belt 502 along the extension direction of the translation track 1, and form a first opening 5041 and a second opening 5042 with the front and rear ends of the conveyor belt 502, respectively. The sorting trolley 5 also includes a blocking part 503 for preventing objects placed on the conveyor belt from passing through the first opening 5041 and / or the second opening 5042.

[0143] The blocking part 503 has several configuration forms. In one configuration, the blocking part 503 includes two blocking units, which are respectively disposed at the first opening 5041 and the second opening 5042. Each blocking unit includes a gate 5031 and a drive source 5032, which drives the gate 5031 to move closer to or away from the first opening 5041 or the second opening 5042. The bracket also has multiple translation wheels 505 that are slidably disposed in the grooves of the translation track 1. When the sorting trolley 5 receives / delivers items, the drive source 5032 drives the gate 5031 away from the first opening 5041 / second opening 5042, allowing items to pass smoothly through the first opening 5041 / second opening 5042 and enter or leave the conveyor belt 502. When the sorting trolley 5 transports items, the drive source 5032 drives the gate 5031 to move to the bottom of the first opening 5041 / second opening 5042, blocking items placed on the conveyor belt 502 and preventing them from falling down through the first opening 5041 / second opening 5042. The drive source 5032 can be a linear displacement drive source or a rotary drive source. When the drive source 5032 is a linear displacement drive source, it drives the gate 5031 to move up and down, allowing the gate 5031 to move linearly back and forth within the range from the bottom of the first opening 5041 / second opening 5042 to above the first opening 5041 / second opening 5042. The linear displacement drive source can specifically be a lead screw motor, electromagnet, etc. When the drive source 5032 is a rotary drive source, it drives the gate 5031 to rotate, allowing the gate 5031 to rotate within the range from the bottom of the first opening 5041 / second opening 5042 to the left / right side of the first opening 5041 / second opening 5042. The rotary drive source can specifically be a stepper motor or a servo motor.

[0144] In another configuration of the blocking part 503, as shown in Figure 20, the blocking part 503 is disposed on the conveyor belt 502, and includes a plurality of stops 507 spaced apart along the extension direction of the conveyor belt 502. The stops 507 extend along the width direction of the conveyor belt 502, and their specific shape is not limited, and can be strip-shaped, plate-shaped, block-shaped, column-shaped, or irregular in shape, etc. When the sorting trolley 5 receives / delivers items, the roller 501 drives the conveyor belt 502 forward, so that one of the stops 507 is located at the bottom of the conveyor belt 502 and the other stop 507 is located at the top of the conveyor belt 502. Items can smoothly pass through the first opening 5041 / second opening 5042 and enter or leave the conveyor belt 502. When the sorting trolley 5 transports items, the roller 501 drives the conveyor belt 502 backward. At this time, both stops 507 are located at the top of the conveyor belt 502, and the item is located between the two stops 507. The forward and backward movement of the item is blocked by the stops 507, preventing it from falling down through the first opening 5041 / second opening 5042.

[0145] In Embodiment 2 of the sorting trolley 5: As shown in Figures 21-25, the sorting trolley 5 includes a trolley support 500, a pair of drive rollers rotatably mounted on the trolley support 500, a conveyor belt 502 connected to the outer periphery of the pair of drive rollers, a pair of baffles 506 distributed on both sides of the conveyor belt 502 along a direction perpendicular to the conveying direction of the conveyor belt 502, a pair of gates 5031 distributed at both ends of the conveyor belt 502 along the conveying direction of the conveyor belt 502, and a lifting drive source and a lifting transmission unit, both mounted on the trolley support 500. The pair of baffles 506 and the pair of gates 5031 are both mounted on the trolley support 500. The pair of gates 5031 are both rotatably mounted on the trolley support 500. The lifting drive source is connected to the pair of gates 5031 through the lifting transmission unit and drives the pair of gates 5031 to move up and down synchronously.

[0146] A pair of baffles 506 are arranged opposite each other, or in other words, a pair of baffles 506 are arranged on the left and right sides of the conveyor belt 502 along the width direction of the conveyor belt 502; while a pair of gates 5031 are arranged opposite each other, or in other words, a pair of baffles 506 are arranged at the front and rear ends of the conveyor belt 502 along the extension direction of the conveyor belt 502. In this embodiment, both baffles 506 are fixed to the trolley bracket 500 and are both higher than the conveyor belt 502. A first opening 5041 and a second opening 5042 are formed between the baffles 506 and the conveyor belt 502 at the front and rear ends of the conveyor belt 502, respectively. A pair of gates 5031 are respectively located at the first opening 5041 and the second opening 5042.

[0147] When the sorting trolley 5 moves to the transfer unit 6 to pick up an item, and when the sorting trolley 5 moves to the unloading chute 702 to unload an item, the lifting drive source drives the two gates 5031 to move up simultaneously and synchronously through the lifting transmission unit. When the gates 5031 move away from the first opening 5041 or the second opening 5042, the gates 5031 do not block the movement. The item moves into the conveyor belt 502 through the first opening 5041 or the second opening 5042, or the item moves out of the conveyor belt 502 through the first opening 5041 or the second opening 5042. When the sorting trolley 5 carrying items is in motion, the lifting drive source drives the front and rear gates 5031 to move down simultaneously and synchronously through the lifting transmission unit until the gates 5031 block the outside of the first opening 5041 or the second opening 5042. Then the gates 5031 play a blocking role, preventing items on the conveyor belt 502 from falling from the first opening 5041 or the second opening 5042, thus effectively preventing items from falling.

[0148] Obviously, this embodiment uses a lifting drive source to drive the two gates 5031 to lift and lower simultaneously and synchronously, thereby reducing costs. Furthermore, in this embodiment, the gates 5031 move by lifting, that is, by translating in the vertical direction. Compared with the vertical flipping movement in the prior art, this reduces the space requirement above the gates 5031, allowing the sorting cart 5 to be better assembled into the sorting system.

[0149] Furthermore, the preferred structure for the sorting trolley 5 to drive the conveyor belt 502 to rotate is as follows: as shown in Figures 21, 24 and 25, the sorting trolley 5 also includes a drive source 5032, which is a motor and fixed on the outer side of the left side baffle 506. The drive source 5032 is connected to a pair of drive rollers through a conveyor transmission assembly. In this embodiment, the conveyor transmission assembly is a synchronous belt pulley assembly; alternatively, one of the drive rollers in the pair can be an electric roller.

[0150] Further, as shown in Figures 21 and 24, the lifting drive source is a motor, and the lifting transmission unit includes a first transmission assembly 54 that is drivenly connected to the motor shaft of the lifting drive source, and a second transmission assembly 55 that is drivenly connected to each gate 5031. Both sets of second transmission assemblies 55 are drivenly connected to the first transmission assembly 54. The first transmission assembly 54 can be a gear and rack assembly, a sprocket and chain assembly, or a synchronous belt pulley assembly, and the second transmission assembly 55 can be a lead screw and nut assembly, a ball screw assembly, or a worm gear assembly. The preferred structures of the first transmission assembly 54 and the second transmission assembly 55 are described below.

[0151] As shown in Figures 21, 22, and 24, the first transmission assembly 54 is distributed on the outer side of the right-side baffle 506, and the second transmission assembly 55 includes a transmission shaft 551 rotatably supported in the trolley bracket 500. The first transmission assembly 54 includes a drive pulley 541 fixed on the motor shaft of the lifting drive source, a first driven pulley 542 fixed on the transmission shaft 551 in each of the second transmission assemblies 55, and a first synchronous belt 543. The first synchronous belt 543 connects to the outer periphery of the drive pulley 541 and the two first driven pulleys 542. Thus, when the lifting drive source drives the drive pulley 541 to rotate, the two first driven pulleys 542 and the first synchronous belt 543 drive the transmission shafts 551 in the two sets of second transmission assemblies 55 to rotate simultaneously and synchronously, thereby driving the two sets of second transmission assemblies 55 to operate synchronously, realizing the synchronous upward or downward movement of the two gates 5031.

[0152] Further, as shown in Figures 21, 22, and 24, the first transmission assembly 54 also includes a motor mounting bracket 544, a tension adjustment groove 545 formed in the motor mounting bracket 544, and a tension adjustment bolt passing through the tension adjustment groove 545. The lifting drive source is fixed to the motor mounting bracket 544, and the motor mounting bracket 544 is locked to the trolley bracket 500 by the tension adjustment bolt. The tension adjustment groove 545 is a waist-shaped groove extending horizontally. Thus, after loosening the tension adjustment bolt, the left and right positions of the motor mounting bracket 544 can be adjusted, which also adjusts the left and right positions of the lifting drive source and the drive pulley 541, and the tension of the first synchronous belt 543 can be adjusted. After adjustment, the tension adjustment bolt can be tightened. Preferably, the first transmission assembly 54 also includes two idler pulleys 546, both rotatably mounted on the trolley bracket 500. The two idler pulleys 546 are distributed on the front and rear sides of the drive pulley 541 and both abut against the outer side of the first synchronous belt 543. The idler pulley 546 is designed so that the left and right portions of the first synchronous belt 543, which extend forward and backward, are in a parallel state.

[0153] Further, as shown in Figures 21, 23, and 25, each group of second transmission components 55 includes two transmission screws 552 distributed at the left and right ends of the gate 5031, a transmission nut 553 connected to the transmission screws 552, a second driven pulley 554 fixed at the lower end of each transmission screw 552, and a second synchronous belt 555. Both transmission screws 552 are vertically arranged and rotatably mounted on the trolley bracket 500 through bearing seats. The right transmission screw 552 near the first transmission component 54 constitutes the aforementioned transmission shaft 551. The right transmission screw 552 is connected to the first transmission component 54, that is, the upper end of the right transmission screw 552 is fixed with the aforementioned first driven pulley 542. The second synchronous belt 555 is connected to the outer periphery of the two second driven pulleys 554 in the second transmission component 55, and the transmission nut 553 is connected to the gate 5031. Thus, the lifting drive source drives the right transmission screw 552 in the two sets of second transmission components 55 to rotate simultaneously and synchronously through the first transmission component 54. The right transmission screw 552 drives the left transmission screw 552 to rotate simultaneously and synchronously through the second driven pulley 554 and the second synchronous belt 555, thereby driving the two gates 5031 to move up or down synchronously through the transmission nut 553.

[0154] Furthermore, as shown in Figure 23, a fitting clearance 556 is provided between the transmission nut 553 and the gate 5031. A connecting bolt 557 extending forward and backward is fixed on the transmission nut 553, and the connecting bolt 557 is assembled in the gate 5031 through a thrust bearing. The setting of the thrust bearing and the fitting clearance 556 allows the gate 5031 to have a certain forward and backward floating amount relative to the transmission nut 553, thereby eliminating deviation and avoiding jamming while ensuring synchronization.

[0155] Furthermore, both the baffle 506 and the gate 5031 are plate components; along the distribution direction of the pair of baffles 506, the gate 5031 covers the area between the pair of baffles 506, so the gate 5031 can cover the conveyor belt 502 in the width direction of the conveyor belt 502, that is, cover the first opening 5041 or the second opening 5042, ensuring the reliability of its anti-drop component.

[0156] Furthermore, the structures of the aforementioned bag supply trolley 33, transfer trolley, bag supply lifting trolley, and sorting lifting trolley are all the same as the structure of the sorting trolley 5.

[0157] Package feeding lifting unit

[0158] As shown in Figures 2, 26, and 27, the package feeding lifting unit 32 is disposed between the package feeding mechanism 3 and the frame 2. The package feeding mechanism 3 includes a package feeding frame 310 and a package feeding platform 31 mounted on the package feeding frame 310. The package feeding platform 31 includes a conveyor belt 311 that rotates continuously under the drive of a motor. The conveyor belt 311 can transport objects in the direction of the package feeding lifting unit 32.

[0159] The package feeding lifting unit 32 includes a fixed frame 322, which is rectangular in shape. A lifting drive source 323 is located at the top of the fixed frame 322, driving a lifting synchronous shaft 3231 to rotate. Two lifting drive wheels are mounted on the lifting synchronous shaft 3231, and two lifting driven wheels are located at the bottom of the fixed frame 322. A lifting transmission component 324 is located between the lifting drive wheels and the lifting driven wheels on the same side. The lifting frame 321 is connected between the two lifting transmission components 324, and a package feeding lifting trolley 325 is fixedly connected within the lifting frame 321. When the lifting drive source 323 drives the lifting synchronous shaft 3231 to rotate, it simultaneously drives the lifting frame 321 and the package feeding lifting trolley 325, which are located between the two lifting transmission components 324, to perform lifting movements.

[0160] To improve work efficiency, the feeding mechanism 3 has two feeding platforms 31 arranged side by side on the feeding frame 310. Each feeding platform 31 is equipped with a corresponding feeding lifting unit 32. The two feeding lifting units 32 are arranged side by side, and there are two feeding carts 33. The feeding platform 31 on the left supplies items to the feeding cart on the left via the feeding lifting unit 32, while the feeding platform 31 on the right supplies items to the feeding cart 33 on the right via the feeding lifting unit 32. With this arrangement, the feeding mechanism 3 can feed materials to both feeding carts 33 simultaneously, facilitating simultaneous operation of both feeding carts 33 and greatly shortening the sorting time.

[0161] The structure of the aforementioned lifting drive source is not limited and can be a stepper motor or a servo motor. The aforementioned lifting drive wheel and lifting driven wheel can be pulleys, gears, or sprockets, while the lifting transmission components can be racks, ropes, belts, or chains, etc., which can convert the rotational motion of the wheels into translational motion.

[0162] Furthermore, the sorting lifting unit 8 and the package feeding lifting unit 32 have the same structure, and a sorting lifting trolley is fixedly connected in its lifting frame. When the lifting drive source drives the lifting synchronous shaft to rotate, it can drive the lifting frame and the sorting lifting trolley, which are set between the two lifting transmission components, to move up and down simultaneously.

[0163] Receiving unit

[0164] As shown in Figures 28 and 29, the receiving unit 7 includes a chute bottom plate 701 and a row of receiving frames 707 arranged sequentially from the inside to the outside along the width direction of the translation track 1. The chute bottom plate 701 is mounted on the frame 2. The chute bottom plate 701 is rectangular and includes a first side 7011a and a second side 7011b arranged opposite each other. The first side 7011a is closer to the sorting trolley 5, and the second side 7011b is farther from the sorting trolley 5; simultaneously, the height of the first side 7011a is greater than the height of the second side 7011b. Due to the inclined arrangement of the chute bottom plate 701, objects falling onto the chute bottom plate 701 from the first side 7011a will slide down to the second side 7011b under gravity and then fall into the receiving frames 707. The chute bottom plate 701 also includes a third side and a fourth side that are arranged opposite to each other. A connecting plate 704 is provided on each of the third side and the fourth side. The chute bottom plate 701 is mounted on the frame 2 through the connecting plate 704.

[0165] As shown in Figures 1, 28, and 29, during the operation of the sorting system, the sorting trolley 5 first moves to the transfer unit 6 to receive the items provided by the transfer unit 6. Then, the sorting trolley 5 moves with the items to a designated position on the chute bottom plate 701. Next, the sorting trolley 5 unloads the items, which fall through the chute bottom plate 701 into the receiving frame 707, completing the unloading process. To prevent items from falling into the gap between the sorting trolley 5 and the chute bottom plate 701 and to ensure smooth unloading, a flexible stop 703 is provided on the first side 7011a of the chute bottom plate 701. The flexible stop 703 helps to shorten the gap between the sorting trolley 5 and the chute bottom plate 701, preventing items from falling, and can automatically rebound during collisions with the sorting trolley 5, making it resistant to damage. Specifically, the flexible stop 703 is made of a flexible material with good resilience, such as silicone or rubber. In addition, lighter items placed on the sorting cart 5 are more likely to fall off than heavier items. When a lighter item falls off the sorting cart 5, it will fall onto the flexible stop 703. The flexible stop 703 has a certain load-bearing capacity, so its load-bearing performance can ensure that the sorted item enters the chute bottom plate 701, thus ensuring the smooth completion of the unloading process.

[0166] Furthermore, when the sorting cart 5 needs to unload the items it carries onto the chute bottom plate 701, the height of the sorting cart 5 is greater than the height of the first side. The height difference between the sorting cart 5 and the chute bottom plate 701 can cause the items leaving the sorting cart 5 to undergo parabolic motion, greatly increasing the likelihood of the items falling onto the chute bottom plate 701.

[0167] Multiple partitions 7014 are spaced apart on the upper surface of the chute bottom plate 701. A discharge chute 702 is formed between two adjacent partitions 7014 and the chute bottom plate 701. The sorting trolley 5 unloads the items it carries into the designated discharge chute 702. The receiving frame 707 includes a material basket located below the discharge chute 702, and items can automatically slide into the material basket along the discharge chute 702.

[0168] The form of the flexible baffle 703 is not limited. It may include several flexible pads arranged along the first side 7011a, or it may include multiple flexible strips 7031, which are spaced apart on the first side 7011a. Compared with a single flexible pad, multiple flexible strips 7031 can reduce the resistance encountered by the sorting cart 5 during movement and reduce their own wear, resulting in a longer overall service life than the flexible pad.

[0169] In the embodiment employing multiple flexible strips 7031 described above, as shown in Figures 30-34, the slide base plate 701 includes a main body 7011 and a bent portion 7012 connected in an L-shape. The main body 7011 includes the aforementioned first side 7011a and second side 7011b, both extending parallel to the length direction of the main body 7011. The first side 7011a is connected to the bent portion 7012. Multiple through holes 7013 are also provided at intervals along the extending direction of the first side 7011a at the connection between the main body 7011 and the bent portion 7012. As shown in Figures 31-32 and 35, the system also includes a pressure plate 706 disposed below the main body 7011. The pressure plate 706 includes a first plate 7061 and a second plate 7062 connected in an L-shape. The first plate 7061 has multiple sets of perforations spaced apart along its length, with the length of the first plate 7061 parallel to the extension direction of the first side 7011a. Each set of perforations includes a first through hole 7061a and a second through hole 7061b spaced apart along the width of the first plate 7061. As shown in Figures 31-32 and 36, one end of the flexible strip 7031 passes sequentially through the through hole 7013, the second through hole 7061b, and the first through hole 7061a, forming a U-shaped portion 7031a. The second plate 7062 is detachably connected to the bending portion 7012. This design prevents the flexible strip 7031 from detaching from the slide base plate 701 during use, making the installation structure more robust and stable.

[0170] Further, as shown in Figures 31-32 and 34-35, the second plate 7062 has a connecting hole 7062a, and the bent portion 7012 has a locking elongated hole 7012a. The locking elongated hole 7012a extends along the width direction of the bent portion 7012, and the inner diameter of the connecting hole 7062a is smaller than the length of the locking elongated hole 7012a. The connecting hole 7062a and the locking elongated hole 7012a are connected by fasteners, specifically bolts. By adjusting the position of the fasteners in the locking elongated hole 7012a, the distance between the first plate 7061 and the main plate 7011 can be changed, facilitating the fixing of flexible strips 7031 of different sizes on the slide base plate 701.

[0171] As shown in Figure 30, multiple reinforcing ribs 705 are also provided at the bottom of the main body 7011, specifically extending along the extension direction of the first side 7011a. This arrangement can increase the structural strength of the main body 7011, helping it to withstand objects of different weights.

[0172] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
