Description

Technical Field

[0001] This invention relates to the field of sorting machine technology, and in particular to an indoor automatic goods sorting machine. Background Technology

[0002] With rapid economic development and changing consumption patterns, especially the rise of e-commerce, the logistics and warehousing industries are facing increasing pressure. To meet the demands of fast, efficient, and accurate logistics services, it is essential to enhance the automation of the warehousing process. Sorting logics and methods vary and can be selected based on specific needs, but the ultimate goal is to organize disorganized items according to certain patterns to facilitate subsequent operations. Current sorting machines primarily rely on cameras to scan barcodes to identify the machine's model information. During loading, the barcodes must be positioned at the top, making automatic sorting based on item height and weight inconvenient. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: an indoor automatic goods sorting machine, comprising a feeding mechanism for feeding goods, the feeding mechanism including a feeding frame, a sorting mechanism for sorting goods by height on the feeding mechanism, the sorting mechanism including a sorting frame fixedly installed on the feeding frame, and an output mechanism for classifying goods of different weights on the sorting mechanism, the output mechanism including a low sorting box fixedly installed on the sorting frame;

[0004] The feeding mechanism includes a push-open frame that is slidably mounted on the feeding frame, a plurality of push-open rollers that are rotatably mounted on the push-open frame, a plurality of feeding rollers that are rotatably mounted on the feeding frame, and an input gear that is fixedly mounted on the feeding roller closest to the sorting frame, with an input transmission belt wrapped around the input gear.

[0005] The sorting mechanism includes a height limit bar and a stop bar fixedly installed on the sorting rack. Two sorting tables are fixedly installed on the sorting rack, and several sorting rollers are rotatably installed on the sorting tables.

[0006] Furthermore, the feeding mechanism also includes roller gears fixedly mounted on the feeding rollers, a connecting transmission belt wrapped around several roller gears, a bottom slide rail fixedly mounted below the feeding frame, an outer push rack fixedly mounted on the push frame, a push spring provided between the push frame and the feeding frame, an inner pull gear rotatably mounted below the feeding frame, the inner pull gear meshing with the outer push rack, an inner pull slide rod slidably mounted inside the bottom slide rail, an inner pull rack slidably mounted on the inner pull slide rod, the inner pull rack meshing with the inner pull gear, and an inner spring provided between the inner pull rack and the inner pull slide rod.

[0007] Furthermore, a blocking rod is slidably mounted on the feeding frame, a docking wheel is rotatably mounted on the blocking rod, an inner slide is slidably mounted on the feeding frame, a docking spring is provided between the inner slide and the blocking rod, an inner pull rod is rotatably mounted on the inner slide, and the inner pull rod is rotatably mounted with the inner pull slide.

[0008] The input drive belt drives the input gear and the feed roller to rotate. Through the connecting drive belt, it drives all the roller gears and the feed roller to rotate. The goods are delivered to the feed roller by the external conveyor belt. The feed roller transports the goods. The goods push the pusher frame to slide along the feeder frame by the pusher roller. The pusher spring is compressed, and the pusher frame slides outward. Through the external pusher rack, it drives the internal pull gear to rotate, thereby driving the internal pull rack and internal pull slide rod to slide along the bottom slide rail. Through the internal pull linkage, it pulls the internal slide frame to slide inward, thereby pushing the stop bar and the docking wheel to slide inward through the docking spring. When the two docking wheels contact, the internal slide frame continues to slide inward. The internal pull rack continues to move, the docking spring is compressed, and the internal spring is stretched. Through the stop bar, the goods are blocked, preventing the subsequent goods from advancing and leaving enough space for the goods in front. When the goods leave the pusher frame, the pusher spring and the internal spring rebound, causing the stop bar to return to its initial position, and the subsequent goods can begin to pass.

[0009] Furthermore, the sorting mechanism also includes three conveyor rollers rotatably mounted on the sorting frame. A docking gear is fixedly mounted on the middle conveyor roller, and conveying gears are fixedly mounted on the conveyor rollers on both sides. An input transmission belt is wrapped around the docking gear, the input gear, and the two conveying gears. Two upper rotating rods are rotatably mounted below the sorting frame, and upper transmission gears are rotatably mounted on the upper rotating rods. An upper transmission belt is wrapped around the upper transmission gears. A lifting motor is slidably mounted below the sorting frame. An intermediate wheel and a lower docking gear are fixedly mounted on the motor shaft of the lifting motor. A transmission motor is fixedly mounted on the sorting table, and a motor gear is fixedly mounted on the motor shaft of the transmission motor.

[0010] Furthermore, two conveying cylinders are installed below the sorting rack. A conveying frame is fixedly installed on the output end of the conveying cylinders. Two conveying wheels are rotatably installed on the conveying frame. A main conveying wheel is rotatably installed on the conveying frame. An upper gear is fixedly installed on the main conveying wheel. A lower gear shaft is rotatably installed on the conveying frame. A lower gear and a side gear are fixedly installed on the lower gear shaft. A transverse transmission belt is wound around the middle wheel and the two side gears. The lower gear meshes with the upper gear. A conveyor belt is wound around the main conveying wheel and the two conveying wheels. When the conveying cylinder extends, the lower engaging gear meshes with the engaging gear.

[0011] Furthermore, two delivery modules are provided below the sorting rack. Each delivery module includes a delivery electric cylinder located below the sorting rack. A lifting plate is fixedly installed on the output end of the delivery electric cylinder. Two delivery frames are fixedly installed on the lifting plate. Four delivery wheels are rotatably installed on the delivery frames. A delivery belt is wrapped around each pair of delivery wheels. A long shaft is fixedly installed on the delivery wheel located inside the drive motor. Two intermediate docking gears are fixedly installed on the long shaft. When the delivery electric cylinder extends, the motor gear meshes with the intermediate docking gear, and the intermediate docking gear meshes with the upper drive gear.

[0012] When goods are fed into the roller conveyor, the delivery cylinder retracts, and the conveying cylinder extends. The extension of the conveying cylinder drives the conveyor frame to rise, which in turn drives the lifting motor to rise. The conveyor belt contacts the lower roller, and the lower engaging gear meshes with the engaging gear. The lifting motor rotates, driving the intermediate wheel and the lower engaging gear to rotate. The lower engaging gear drives the engaging gear to rotate, which in turn drives the conveying gear, conveying roller, and delivery roller to rotate via the input transmission belt, transporting the goods to the sorting table. The intermediate wheel drives the side gear, lower gear shaft, and lower gear to rotate via the transverse transmission belt, which in turn drives the upper gear and the main conveyor wheel to rotate, driving the conveyor belt to move. This drives the lower roller to rotate, which in turn drives the sorting roller to rotate. The sorting roller transports the goods toward the height limit bar and the barrier bar. Goods that are too tall will be blocked by the height limit bar, while goods that are shorter than the height limit bar will be transported to the sorting table near the barrier bar.

[0013] Once the goods are transported to the sorting table, the conveyor cylinder retracts, and the delivery cylinder rises, thereby raising the lifting plate and delivery frame. This causes the delivery belt to contact the lower roller. At this point, the middle connecting gear meshes with the upper transmission gear, and the middle connecting gear meshes with the motor gear. The transmission motor drives the motor gear to rotate, which in turn drives the middle connecting gear to rotate, and simultaneously drives the upper transmission gear to rotate. The upper transmission gear drives the lower transmission gear to rotate via the upper transmission belt, which in turn drives the lower transmission wheel and the lower wheel to rotate via the lower transmission belt. The delivery belt drives the lower roller to rotate, and the lower roller drives the sorting roller to rotate. The sorting roller transports the goods on the sorting table to the output roller. Then, the transmission motor stops rotating, causing the lower transmission roller to stop rotating.

[0014] Furthermore, the output mechanism includes a high sorting box fixedly installed on the sorting rack, and discharge ports are provided on the high sorting box and the low sorting box. A blocking block is slidably installed inside both the low sorting box and the high sorting box. A blocking spring is provided between the blocking block and the low sorting box, and a blocking spring is provided between the blocking block and the high sorting box. An arc surface is provided on the blocking block.

[0015] Furthermore, both the low sorting box and the high sorting box are equipped with a discharge module. The discharge module includes a lifting conveyor frame that is slidably installed inside the low sorting box and the high sorting box. A downward pressure spring is installed between the lifting conveyor frame and the low sorting box, and a downward pressure spring is installed between the lifting conveyor frame and the high sorting box. Several output rollers are rotatably installed on the lifting conveyor frame, and output gears are fixedly installed on the output rollers. Output belts are wound around the output gears. A lower rotating rod is rotatably installed below the lifting conveyor frame, and a lower wheel is rotatably installed on the lower rotating rod. A lower transmission wheel is fixedly installed on the lower wheel. An internal gear is fixedly installed on the output roller above the lower wheel. The internal gear meshes with the lower wheel. A lower transmission gear is rotatably installed on the lower rotating rod, and a lower transmission belt is wound around the lower transmission gear and the lower transmission wheel. The lower rotating rod is rotatably installed with the upper transmission belt, and an upper transmission belt is wound around the lower transmission gear and the upper transmission gear.

[0016] When the goods fall onto the output rollers, the weight of the goods causes the lifting conveyor to descend along the low or high sorting box. The pressure spring is compressed, and the blocking block supports the lifting conveyor. When the weight of the lifting conveyor and the goods reaches a certain level, it will push the blocking block to slide outward, compress the blocking spring, and the lifting conveyor and the goods will fall to the lower discharge port. If the weight of the lifting conveyor and the goods is insufficient to push the blocking block to slide outward, the goods will be at the upper discharge port.

[0017] When the lifting conveyor stops descending, the lower drive wheel rotates again. The lower drive gear drives the lower drive wheel and the lower wheel to rotate through the lower drive belt, which in turn drives the internal gear and the output roller to rotate. The output roller is then driven to rotate through the output gear and the output belt, and the goods are sent out from the designated discharge port through the output roller.

[0018] When the lifting conveyor frame is raised or lowered, it will drive the lower rotating rod to rotate, which in turn drives the upper rotating rod to rotate. The upper transmission gear can always drive the lower wheel to rotate.

[0019] The advantages of this invention compared with the prior art are: (1) The feeding mechanism and the sorting mechanism of this invention work together to automatically transport the goods to be sorted to the sorting table. The feeding mechanism uses a blocking bar to make a certain gap between each goods, which facilitates sorting; (2) The sorting mechanism and the output mechanism of this invention work together to sort the goods separately by height and weight, which has high sorting efficiency; (3) When the conveying electric cylinder of this invention is raised, the feeding mechanism and the sorting mechanism work together to transport the goods to the sorting table. When the output electric cylinder is raised, the sorting mechanism and the output mechanism work together to send the goods out from different outlets according to weight, which has a high degree of automation and good continuity.

Detailed Implementation

[0036] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0037] Example: Reference Figures 1-15 An indoor automatic goods sorting machine includes a feeding mechanism for feeding goods, the feeding mechanism including a feeding frame 101, a sorting mechanism for sorting goods by height on the feeding mechanism, a sorting frame 201 fixedly installed on the feeding frame 101, and an output mechanism for classifying goods of different weights on the sorting mechanism, the output mechanism including a low sorting box 301 fixedly installed on the sorting frame 201;

[0038] The feeding mechanism includes a push-open frame 106 slidably mounted on the feeding frame 101, a plurality of push-open rollers 107 rotatably mounted on the push-open frame 106, a plurality of feeding rollers 102 rotatably mounted on the feeding frame 101, and an input gear 104 fixedly mounted on the feeding roller 102 closest to the sorting frame 201, with an input transmission belt 105 wound around the input gear 104.

[0039] The sorting mechanism includes a height limit bar 202 and a stop bar 208 fixedly installed on the sorting frame 201. Two sorting tables 206 are fixedly installed on the sorting frame 201, and several sorting rollers 207 are rotatably installed on the sorting tables 206.

[0040] like Figures 2-5 As shown, the feeding mechanism also includes roller gears 103 fixedly mounted on the feeding rollers 102. A connecting transmission belt 120 is wound around several roller gears 103. A bottom slide rail 116 is fixedly mounted below the feeding frame 101. An external push rack 118 is fixedly mounted on the push frame 106. A push spring 108 is provided between the push frame 106 and the feeding frame 101. An internal pull gear 117 is rotatably mounted below the feeding frame 101. The internal pull gear 117 meshes with the external push rack 118. An internal pull rod 114 is slidably mounted inside the bottom slide rail 116. An internal pull rack 115 is slidably mounted on the internal pull rod 114. The internal pull rack 115 meshes with the internal pull gear 117. An internal spring 119 is provided between the internal pull rack 115 and the internal pull rod 114.

[0041] like Figures 2-5 As shown, a blocking rod 109 is slidably mounted on the feeding frame 101, a docking wheel 110 is rotatably mounted on the blocking rod 109, an inner slide 112 is slidably mounted on the feeding frame 101, a docking spring 111 is provided between the inner slide 112 and the blocking rod 109, an inner pull rod 113 is rotatably mounted on the inner slide 112, and the inner pull rod 113 is rotatably mounted with the inner pull slide rod 114.

[0042] The input drive belt 105 drives the input gear 104 and the feed roller 102 to rotate. Through the connecting drive belt 120, it drives all the roller gears 103 and the feed roller 102 to rotate. Goods are fed onto the feed roller 102 by the external conveyor belt. The feed roller 102 transports the goods. The goods are pushed by the push roller 107 to slide the push frame 106 along the feed frame 101. The push spring 108 is compressed, and the push frame 106 slides outward, driving the inner pull gear 117 to rotate via the outer push rack 118. This, in turn, drives the inner pull rack 115 and the inner pull slide rod 114 to slide along the bottom slide rail 116. Pulling rod 113 pulls inner slide 112 inward, thereby pushing blocking rod 109 and docking wheel 110 inward through docking spring 111. When the two docking wheels 110 contact, inner slide 112 continues to slide inward, inner pull rack 115 continues to move, docking spring 111 is compressed, and inner spring 119 is stretched. The blocking rod 109 blocks the goods, preventing subsequent goods from advancing and leaving sufficient space for the goods in front. When the goods leave push frame 106, push spring 108 and inner spring 119 rebound, causing blocking rod 109 to return to its initial position, and subsequent goods can begin to pass.

[0043] like Figures 6-11 As shown, the sorting mechanism also includes three conveyor rollers 203 rotatably mounted on the sorting frame 201. A docking gear 204 is fixedly mounted on the middle conveyor roller 203, and conveyor gears 205 are fixedly mounted on the conveyor rollers 203 on both sides. An input transmission belt 105 is wrapped around the docking gear 204, the input gear 104, and the two conveyor gears 205. Two upper rotating rods 232 are rotatably mounted below the sorting frame 201. An upper transmission gear 229 is rotatably mounted on the upper rotating rod 232. An upper transmission belt 233 is wrapped around the upper transmission gear 229. A lifting motor 219 is slidably mounted below the sorting frame 201. An intermediate wheel 221 and a lower docking gear 220 are fixedly mounted on the motor shaft of the lifting motor 219. A drive motor 230 is fixedly mounted on the sorting table 206. A motor gear 231 is fixedly mounted on the motor shaft of the drive motor 230.

[0044] like Figures 6-11As shown, two conveyor cylinders 209 are arranged below the sorting rack 201. A conveyor frame 210 is fixedly installed on the output end of the conveyor cylinder 209. Two conveyor wheels 211 are rotatably installed on the conveyor frame 210. A main conveyor wheel 212 is rotatably installed on the conveyor frame 210. An upper gear 214 is fixedly installed on the main conveyor wheel 212. A lower gear shaft 216 is rotatably installed on the conveyor frame 210. A lower gear 215 and a side gear 217 are fixedly installed on the lower gear shaft 216. A transverse transmission belt 218 is wound around the intermediate wheel 221 and the two side gears 217. The lower gear 215 meshes with the upper gear 214. A conveyor belt 213 is wound around the main conveyor wheel 212 and the two conveyor wheels 211. When the conveyor cylinder 209 extends, the lower docking gear 220 meshes with the docking gear 204.

[0045] like Figures 6-11 As shown, two delivery modules are provided below the sorting rack 201. The delivery module includes a delivery cylinder 222 located below the sorting rack 201. A lifting plate 223 is fixedly installed on the output end of the delivery cylinder 222. Two delivery frames 224 are fixedly installed on the lifting plate 223. Four delivery wheels 225 are rotatably installed on the delivery frames 224. A delivery belt 226 is wrapped around each pair of delivery wheels 225. A long shaft 227 is fixedly installed on the delivery wheels 225 located inside the drive motor 230. Two intermediate docking gears 228 are fixedly installed on the long shaft 227. When the delivery cylinder 222 extends, the motor gear 231 meshes with the intermediate docking gear 228, and the intermediate docking gear 228 meshes with the upper drive gear 229.

[0046] When goods are fed into roller 102, the delivery cylinder 222 retracts, and the conveying cylinder 209 extends. The extension of the conveying cylinder 209 drives the conveyor frame 210 to rise, thereby driving the lifting motor 219 to rise. The conveyor belt 213 contacts the lower roller 234, and the lower engaging gear 220 meshes with the engaging gear 204. The rotation of the lifting motor 219 drives the intermediate wheel 221 and the lower engaging gear 220 to rotate. The lower engaging gear 220 drives the engaging gear 204 to rotate, thereby driving the conveying gear 205, the conveying roller 203, and the feed roller 102 to rotate via the input transmission belt 105. The goods are transported to the sorting table 206. The intermediate wheel 221 drives the side gear 217, the lower gear shaft 216 and the lower gear 215 to rotate through the transverse transmission belt 218, which in turn drives the upper gear 214 and the main conveyor wheel 212 to rotate, which in turn drives the conveyor belt 213 to move, thereby driving the lower roller 234 to rotate, which in turn drives the sorting roller 207 to rotate. The sorting roller 207 transports the goods toward the height limit bar 202 and the barrier bar 208. Goods that are too tall will be blocked by the height limit bar 202, and goods that are shorter than the height limit bar 202 will be transported to the sorting table 206 near the barrier bar 208.

[0047] When the goods are conveyed onto the sorting table 206, the conveyor cylinder 209 retracts, and the delivery cylinder 222 rises, thereby causing the lifting plate 223 and the delivery frame 224 to rise. This brings the delivery belt 226 into contact with the lower roller 234. At this time, the middle docking gear 228 meshes with the upper transmission gear 229, and the middle docking gear 228 meshes with the motor gear 231. The drive motor 230 drives the motor gear 231 to rotate, thereby driving the middle docking gear 228 to rotate, and simultaneously driving the upper transmission gear 234 to rotate. When gear 229 rotates, the upper transmission gear 229 drives the lower transmission gear 316 to rotate via the upper transmission belt 233. The lower transmission belt 315 drives the lower transmission wheel 313 and the lower wheel 312 to rotate. The delivery belt 226 drives the lower roller 234 to rotate. The lower roller 234 drives the sorting roller 207 to rotate. The sorting roller 207 transports the goods on the sorting table 206 to the output roller 307. Then the transmission motor 230 stops rotating, causing the lower transmission wheel 313 to stop rotating.

[0048] like Figures 12-15 As shown, the output mechanism includes a high sorting box 302 fixedly installed on the sorting rack 201. The high sorting box 302 and the low sorting box 301 are provided with discharge ports 311. Both the low sorting box 301 and the high sorting box 302 are slidably installed with blocking blocks 304. A blocking spring 305 is provided between the blocking block 304 and the low sorting box 301, and between the blocking block 304 and the high sorting box 302. The blocking block 304 is provided with an arc surface.

[0049] like Figures 12-15 As shown, both the low sorting box 301 and the high sorting box 302 are equipped with a discharge module. The discharge module includes a lifting conveyor frame 306 slidably installed within the low sorting box 301 and the high sorting box 302. A downward pressure spring 303 is installed between the lifting conveyor frame 306 and the low sorting box 301, and between the lifting conveyor frame 306 and the high sorting box 302. Several output rollers 307 are rotatably mounted on the lifting conveyor frame 306. Output gears 308 are fixedly mounted on the output rollers 307. An output belt 309 is wound around the output gears 308. A lower rotating rod 314 is rotatably mounted below 06. A lower wheel 312 is rotatably mounted on the lower rotating rod 314. A lower transmission wheel 313 is fixedly mounted on the lower wheel 312. An internal gear 310 is fixedly mounted on the output roller 307 above the lower wheel 312. The internal gear 310 meshes with the lower wheel 312. A lower transmission gear 316 is rotatably mounted on the lower rotating rod 314. A lower transmission belt 315 is wound around the lower transmission gear 316 and the lower transmission wheel 313. The lower rotating rod 314 is rotatably mounted with the upper transmission belt 233. An upper transmission belt 233 is wound around the lower transmission gear 316 and the upper transmission gear 229.

[0050] When the goods fall onto the output roller 307, under the action of the goods' gravity, the lifting conveyor 306 will descend along the low sorting box 301 or the high sorting box 302. The pressure spring 303 will be compressed, and the blocking block 304 will support the lifting conveyor 306. When the weight of the lifting conveyor 306 and the goods reaches a certain weight, it will push the blocking block 304 to slide outward, and the blocking spring 305 will be compressed. The lifting conveyor 306 and the goods will fall to the lower discharge port 311. If the weight of the lifting conveyor 306 and the goods is insufficient to push the blocking block 304 to slide outward, the goods will be at the upper discharge port 311.

[0051] When the lifting conveyor frame 306 stops descending, the lower drive wheel 313 rotates again. The lower drive gear 316 drives the lower drive wheel 313 and the lower wheel 312 to rotate through the lower drive belt 315, thereby driving the internal gear 310 and the output roller 307 to rotate. The output roller 307 is driven to rotate through the output gear 308 and the output belt 309, and the goods are sent out from the designated discharge port 311 through the output roller 307.

[0052] When the lifting conveyor frame 306 is raised or lowered, it will drive the lower rotating rod 314 to rotate, which in turn drives the upper rotating rod 232 to rotate. The upper transmission gear 229 can always drive the lower wheel 312 to rotate.

[0053] The working principle of an indoor automatic goods sorting machine disclosed in this invention is as follows: Goods are delivered to the feed roller 102 by an external conveyor belt. The delivery cylinder 222 retracts, and the conveying cylinder 209 extends. The extension of the conveying cylinder 209 drives the conveyor frame 210 to rise, thereby driving the lifting motor 219 to rise. The conveyor belt 213 contacts the lower roller 234, and the lower engaging gear 220 meshes with the engaging gear 204. The rotation of the lifting motor 219 drives the intermediate wheel 221 and the lower engaging gear 220 to rotate. The lower engaging gear 220 drives the engaging gear 204 to rotate, thereby driving the conveying gear 205, the conveying roller 203, and the feed roller 102 to rotate via the input transmission belt 105. The input transmission belt 105 drives the input gear 104 and the feed roller 102 to rotate. Through the connecting transmission belt 120, all roller gears 103 and the feed roller 102 rotate. The feed roller 102 conveys the goods. The push roller 107 pushes the push frame 106 to slide along the feed frame 101, compressing the push spring 108. The push frame 106 slides outward, driving the inner pull gear 117 to rotate via the outward push rack 118. This causes the inner pull rack 115 and inner pull slide rod 114 to slide along the bottom slide rail 116. The inner pull connecting rod 113 pulls the inner slide 112 inward, which in turn pushes the blocking rod 109 and the docking wheel 110 inward via the docking spring 111. When the two docking wheels 110 contact each other, the inner slide 112 continues to slide inward, the inner pull rack 115 continues to move, the docking spring 111 is compressed, and the inner spring 119 is stretched. The blocking rod 109 blocks the goods, preventing subsequent goods from advancing and leaving sufficient space for the goods at the front. When the goods leave the push frame 106, the push spring 108 and the inner spring 119 rebound, causing the blocking rod 109 to return to its initial position, and subsequent goods can begin to pass through. The intermediate wheel 221 drives the side gear 217, the lower gear shaft 216 and the lower gear 215 to rotate via the transverse transmission belt 218, which in turn drives the upper gear 214 and the main conveyor wheel 212 to rotate, which in turn drives the conveyor belt 213 to move, thereby driving the lower roller 234 to rotate, which in turn drives the sorting roller 207 to rotate. The sorting roller 207 transports the goods toward the height limit bar 202 and the barrier bar 208. Goods that are too tall will be blocked by the height limit bar 202, and goods that are shorter than the height limit bar 202 will be transported to the sorting table 206 near the barrier bar 208.When the goods are conveyed onto the sorting table 206, the conveyor cylinder 209 retracts, and the delivery cylinder 222 rises, thereby causing the lifting plate 223 and the delivery frame 224 to rise. This brings the delivery belt 226 into contact with the lower roller 234. At this time, the middle docking gear 228 meshes with the upper transmission gear 229, and the middle docking gear 228 meshes with the motor gear 231. The drive motor 230 drives the motor gear 231 to rotate, thereby driving the middle docking gear 228 to rotate, and simultaneously driving the upper transmission gear 234 to rotate. When gear 229 rotates, the upper transmission gear 229 drives the lower transmission gear 316 to rotate via the upper transmission belt 233. The lower transmission belt 315 drives the lower transmission wheel 313 and the lower wheel 312 to rotate. The delivery belt 226 drives the lower roller 234 to rotate. The lower roller 234 drives the sorting roller 207 to rotate. The sorting roller 207 transports the goods on the sorting table 206 to the output roller 307. Then the transmission motor 230 stops rotating, causing the lower transmission wheel 313 to stop rotating. When the goods fall onto the output roller 307, under the action of the goods' gravity, the lifting conveyor 306 will descend along the low sorting box 301 or the high sorting box 302. The pressure spring 303 will be compressed, and the blocking block 304 will support the lifting conveyor 306. When the weight of the lifting conveyor 306 and the goods reaches a certain weight, it will push the blocking block 304 to slide outward, and the blocking spring 305 will be compressed. The lifting conveyor 306 and the goods will fall to the lower discharge port 311. If the weight of the lifting conveyor 306 and the goods is insufficient to push the blocking block 304 to slide outward, the goods will be at the upper discharge port 311. When the lifting conveyor frame 306 stops descending, the lower drive wheel 313 rotates again. The lower drive gear 316 drives the lower drive wheel 313 and the lower wheel 312 to rotate through the lower drive belt 315, thereby driving the internal gear 310 and the output roller 307 to rotate. The output roller 307 is driven to rotate through the output gear 308 and the output belt 309, and the goods are sent out from the designated discharge port 311 through the output roller 307.
