The cargo sorting machine in the prior art mainly uses the camera to scan the model information of the item barcode. When loading, the barcode needs to be adjusted to the top, and it cannot automatically sort according to the height and weight of the goods, which is inconvenient to use. Summary of the invention

[0005] Furthermore, a blocking rod is slidably installed on the feeding rack, a docking wheel is rotatably installed on the blocking rod, an inner slide is slidably installed on the feeding rack, a docking spring is arranged between the inner slide and the blocking rod, an inner pull connecting rod is rotatably installed on the inner slide, and the inner pull connecting rod is rotatably installed with the inner pull sliding rod.

[0006] The input transmission belt drives the input gear and the feed roller to rotate, and the connecting transmission belt drives all the roller gears and the feed roller to rotate. The goods are sent to the feed roller by the external conveyor belt, and the feed roller transports the goods. The goods push the push-open frame to slide along the feed frame through the push-open roller, and the push-open spring is compressed. The push-open frame slides outward and drives the inner pull gear to rotate through the outer push rack, thereby driving the inner pull rack and the inner pull slide bar to slide along the bottom slide rail, and the inner pull connecting rod pulls the inner slide to slide inward, thereby pushing the blocking rod and the docking wheel to slide inward through the docking spring. When the two docking wheels contact, the inner slide continues to slide inward, the inner pull rack continues to move, the docking spring is compressed, and the inner spring is stretched, blocking the goods through the blocking rod, blocking the subsequent goods from moving forward, leaving enough space for the front goods, and when the goods leave the push-open frame, the push-open spring and the inner spring rebound, so that the blocking rod returns to the initial position, and the subsequent goods can start to pass.

[0007] Furthermore, the sorting mechanism also includes three conveying rollers rotatably mounted on the sorting frame, a docking gear is fixedly mounted on the middle conveying roller, conveying gears are fixedly mounted on the conveying rollers on both sides, input transmission belts are wrapped around the docking gears, input gears and two conveying gears, two upper rotating rods are rotatably mounted below the sorting frame, upper transmission gears are rotatably mounted on the upper rotating rods, upper transmission gears are 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] When the goods are fed into the roller conveyor, the delivery electric cylinder contracts and the delivery electric cylinder extends. The extension of the delivery electric cylinder drives the conveyor frame to rise, thereby driving the lifting motor to rise, the conveyor belt contacts the lower roller, the lower docking gear engages with the docking gear, and the lifting motor rotates to drive the intermediate wheel and the lower docking gear to rotate. The lower docking gear drives the docking gear to rotate, thereby driving the conveying gear, conveying roller and delivery roller to rotate through the input transmission belt to transport the goods to the sorting platform. The intermediate wheel drives the side gear, the lower gear shaft and the lower gear to rotate through the transverse transmission belt, drives the upper gear and the conveying main wheel to rotate, drives the conveyor belt to move, thereby drives the lower roller to rotate, thereby drives the sorting roller to rotate, and transports the goods toward the height limit rod and the blocking rod through the sorting roller. The goods that are too high will be blocked by the height limit rod, and the goods whose height is lower than the height limit rod will be transported to the sorting platform close to the blocking rod.

[0011] When the goods are transported to the sorting platform, the conveying electric cylinder contracts and the delivery electric cylinder rises, thereby driving the lifting plate and the delivery rack to rise, so that the delivery belt contacts the lower roller. At this time, the middle docking gear is meshed with the upper transmission gear, and the middle docking gear is meshed with the motor gear. The transmission motor drives the motor gear to rotate, thereby driving the middle docking gear to rotate, and at the same time drives the upper transmission gear to rotate. The upper transmission gear drives the lower transmission gear to rotate through the upper transmission belt, and drives the lower transmission wheel and the lower wheel to rotate through the lower transmission belt. The delivery belt drives the lower roller to rotate, and the lower roller drives the sorting roller to rotate.

[0014] When the goods fall onto the output roller, the gravity of the goods will cause the lifting conveyor frame to descend along the low sorting box or the high sorting box, the downward pressure spring will be compressed, and the blocking block will hold the lifting conveyor frame. When the weight of the lifting conveyor frame and the goods reaches a certain weight, the blocking block will be pushed to slide outward, the blocking spring will be compressed, and the lifting conveyor frame and the goods will fall to the discharge port below. If the weight of the lifting conveyor frame and the goods is not enough to push the blocking block to slide outward, the goods will be at the discharge port above.

[0015] When the lifting conveyor frame stops descending, the lower transmission wheel rotates again, and the lower transmission gear drives the lower transmission wheel and the lower wheel to rotate through the lower transmission belt, thereby driving the inner gear and the output roller to rotate, and the output roller is 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.

[0016] When the lifting conveyor frame is lifted or lowered, the lower rotating rod will be driven to rotate, thereby driving the upper rotating rod to rotate, and the upper transmission gear can always drive the lower wheel to rotate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) the feeding mechanism and the sorting mechanism provided in the present invention cooperate to automatically transport the goods to be sorted to the sorting platform, and the feeding mechanism uses the blocking rod to allow a certain gap between each of the goods, which is convenient for sorting; (2) the sorting mechanism and the output mechanism provided in the present invention cooperate to sort the goods separately by height and weight, and the sorting efficiency is high; (3) when the conveying electric cylinder provided in the present invention is raised, the feeding mechanism and the sorting mechanism cooperate to transport the goods to the sorting platform, and when the output electric cylinder is raised, the sorting mechanism and the output mechanism cooperate to send the goods out from different discharge ports according to weight, with a high degree of automation and good continuity.

[0049] The working principle of an indoor automatic cargo sorting machine disclosed in the present invention is as follows: the cargo is sent to the feeding roller 102 by an external conveyor belt, the feeding electric cylinder 222 contracts, the feeding electric cylinder 209 extends, the feeding electric cylinder 209 extends and drives the conveying frame 210 to rise, thereby driving the lifting motor 219 to rise, the conveyor belt 213 contacts the lower roller 234, the lower docking gear 220 engages with the docking gear 204, the lifting motor 219 rotates and drives the intermediate wheel 221 and the lower docking gear 220 to rotate, the lower docking gear 220 drives the docking gear 204 to rotate, thereby driving the conveying gear 205, the conveying roller 203 and the feeding roller 102 to rotate through the input transmission belt 105, the input transmission belt 105 drives the input gear 104 and the feeding roller 102 to rotate, and drives all the roller gears 103 and the feeding roller 102 to rotate through the connecting transmission belt 120, the feeding roller 102 transports the cargo, and the cargo passes through The pushing roller 107 pushes the pushing frame 106 to slide along the feeding frame 101, the pushing spring 108 is compressed, and the pushing frame 106 slides outward and drives the inner pull gear 117 to rotate through the outward pushing rack 118, thereby driving the inner pull rack 115 and the inner pull slide bar 114 to slide along the bottom slide rail 116, and pulling the inner slide 112 inward through the inner pull connecting rod 113, thereby pushing the blocking rod 109 and the docking wheel 110 to slide inward through the docking spring 111. When the two docking wheels 110 contact, 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, blocking the goods through the blocking rod 109, blocking the subsequent goods from advancing, leaving enough space for the front goods, and when the goods leave the pushing frame 106, the pushing spring 108 and the inner spring 119 rebound, so that the blocking rod 109 returns to the initial position, and the subsequent goods can start to pass. The middle 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, drives the upper gear 214 and the conveying main wheel 212 to rotate, drives the conveyor belt 213 to move, thereby drives the lower roller 234 to rotate, thereby drives the sorting roller 207 to rotate, and the goods are transported toward the height limit rod 202 and the blocking rod 208 through the sorting roller 207. The goods that are too high will be blocked by the height limit rod 202, and the goods whose height is lower than the height limit rod 202 will be transported to the sorting platform 206 close to the blocking rod 208.When the goods are transported to the sorting platform 206, the transport cylinder 209 contracts and the delivery cylinder 222 rises, thereby driving the lifting plate 223 and the delivery frame 224 to rise, so that the delivery belt 226 contacts 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 transmission motor 230 drives the motor gear 231 to rotate, thereby driving the middle docking gear 228 to rotate, and at the same time driving the upper transmission gear 229. The gear 229 rotates, the upper transmission gear 229 drives the lower transmission gear 316 to rotate through the upper transmission belt 233, drives the lower transmission wheel 313 and the lower wheel 312 to rotate through the lower transmission belt 315, the delivery belt 226 drives the lower roller 234 to rotate, the lower roller 234 drives the sorting roller 207 to rotate, and the goods on the sorting platform 206 are transported to the output roller 307 through the sorting roller 207, and then the transmission motor 230 stops rotating, so that the lower transmission wheel 313 stops rotating. When the goods fall onto the output roller 307, the lifting and conveying frame 306 will be lowered along the low sorting box 301 or the high sorting box 302 under the action of the gravity of the goods, the downward pressure spring 303 will be compressed, and the blocking block 304 will hold the lifting and conveying frame 306. When the weight of the lifting and conveying frame 306 and the goods reaches a certain weight, the blocking block 304 will be pushed to slide outward, the blocking spring 305 will be compressed, and the lifting and conveying frame 306 and the goods will fall to the discharge port 311 below. If the weight of the lifting and conveying frame 306 and the goods is not enough to push the blocking block 304 to slide outward, the goods will be at the discharge port 311 above. When the lifting conveyor frame 306 stops descending, the lower transmission wheel 313 rotates again, and the lower transmission gear 316 drives the lower transmission wheel 313 and the lower wheel 312 to rotate through the lower transmission belt 315, thereby driving the internal gear 310 and the output roller 307 to rotate, and drives the output roller 307 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.
