Description

Technical Field

[0001] This invention relates to the field of automatic material sorting technology, and more specifically, to an automatic material sorting device. Background Technology

[0002] With the rapid development of the tobacco retail market, tobacco orders are showing significant characteristics of being diverse, small-batch, high-frequency, and personalized, which places higher demands on the flexibility, efficiency, and precision of the sorting system.

[0003] Traditional tobacco sorting primarily relies on manual or semi-manual assisted sorting methods, which are not only labor-intensive and have seen rising labor costs year after year, but also have low sorting efficiency, making it difficult to meet the delivery needs of large-scale orders. Furthermore, manual sorting is affected by factors such as worker fatigue and lack of concentration, resulting in significant fluctuations in sorting accuracy, frequent mis-sorting, omissions, and material mixing, and frequent machine downtime due to manual replenishment, severely limiting the continuous operating time of the equipment. In addition, when handling mixed orders of multiple product categories, traditional sorting methods require frequent changes of tooling and adjustments to sorting stations, resulting in long order changeover times and slow response speeds, failing to meet the increasingly personalized order demands of the tobacco industry. Therefore, there is an urgent need for an automated material sorting device to solve these problems. Summary of the Invention

A first spring is sleeved on the outer circumference of the first guide post. The stop plate is located on one side of the pressing groove.

[0015] The beneficial effects of this invention are: This invention provides an automatic material sorting device that adopts a multi-station independent modular sorting component design. Each sorting component corresponds to a specific specification or category of tobacco box. The corresponding station can be accurately started, stopped, and operated independently according to order requirements, realizing arbitrary combination and mixing of different series of cigarettes for sorting. The entire process does not require changing tooling fixtures or adjusting equipment parameters, which greatly shortens the order changeover time and significantly improves the order response speed and sorting flexibility. At the same time, it is equipped with a fully automatic closed-loop replenishment system. When the material in the storage bin is insufficient, the feeding component inside the top cavity automatically starts the replenishment process. That is, the second motor drives the slide plate to move horizontally to the picking position through the second threaded screw and the second threaded sleeve. The third motor drives the third threaded screw to drive the movable clamping plate and the fixed clamping plate to clamp the tobacco box. The cooperation of the guide cylinder and the third guide column ensures the stability of the clamping plate movement and prevents the tobacco box from falling or tilting during the transfer. The slide plate drives the clamped tobacco box to move accurately above the storage bin and then releases it to complete the replenishment. The entire process does not require manual intervention and significantly extends the continuous operation time of the equipment.

[0016] This invention provides an automatic material sorting device. Through a three-section structure—a toothed section at the front, a toothless groove in the middle, and a toothed section at the rear—a single first rack can achieve a fully synchronized process of pre-compression, spring energy storage, secondary pressurization, material pushing and discharging, and step-by-step reset. During the pushing process, the abutment plate precisely presses against the second-to-last and third-to-last tobacco boxes in the sorting box, isolating the weight load of the stacked tobacco boxes above. This avoids the problem in traditional sorting devices where the bottom tobacco box to be pushed suffers increased frictional resistance, jamming, or even inability to be pushed due to the heavy pressure from above. It also prevents the tobacco boxes above from falling during the pushing process. The material discharge chute, formed by the baffle frame and the bottom of the sorting box, allows only one box to pass at a time, eliminating sorting errors such as multiple boxes being accidentally discharged or mixed materials. In addition, the first spring can adaptively buffer the clamping force of the damping plate, ensuring that the tobacco boxes are firmly fixed and avoiding problems such as deformation, wrinkles, scratches on the printing layer, and breakage of internal cigarettes caused by excessive compression. It can also accommodate minor dimensional errors of tobacco boxes from different batches. Furthermore, the first baffle on the first vertical plate precisely limits the swing arm by restricting the maximum swing angle of the first connecting plate, ensuring the consistency and repeatability of each energy storage and pushing stroke, further improving the stability of the sorting process.

[0017] This invention provides an automatic material sorting device that employs a step-by-step reset design: the pusher plate resets first, and the abutment plate releases later. After the pusher plate is pushed, when the sliding seat resets to align with the toothless groove in the middle of the first rack and the second gear disc, the abutment plate stops moving and remains in a pressed state. This avoids the situation where tobacco boxes above the sorting box fall prematurely during the pusher plate reset process, pressing down on the front end of the pusher plate and preventing it from resetting. This solves the problem of material jamming and blockage that easily occurs during the reset process of traditional devices, reducing equipment downtime for maintenance. In addition, the sorting components adopt a modular design, which can flexibly increase or decrease the number of workstations according to the capacity requirements of different production lines. When a single sorting component malfunctions, it can be disassembled and repaired individually without affecting the normal operation of other workstations, further improving the overall utilization rate of the production line and having broad industrial application prospects.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0032] Please see Figures 1-11An automatic material sorting device includes a conveyor belt 1 and a storage bin 4 disposed on one side of the conveyor belt 1. The top of the storage bin 4 is provided with a top cavity 3. A feeding platform 6 is fixedly connected to one side of the conveyor belt 1. The top of the feeding platform 6 is provided with sorting components 5 evenly distributed for sorting and feeding tobacco boxes 10. The storage bin 4 is fixedly connected to the top of the sorting components 5. A support frame 9 is fixedly connected to one side of the top cavity 3 and the storage box 4. A feeding component 7 for transferring the tobacco box 10 into the storage box 4 and a pushing component 2 for pushing the tobacco box 10 out of the sorting component 5 are provided below the top cavity 3. The sorting component 5 includes a sorting box 501 fixedly connected to the bottom outer wall of the storage box 4. A baffle 502 is fixedly connected to the outer wall of the sorting box 501 near the conveyor belt 1 to prevent tobacco boxes 10 from accidentally leaking out. The bottom end of the baffle 502 and one side of the sorting box 501 form a discharge chute 503 for only one tobacco box 10 to be discharged. On the side of the sorting box 501 away from the baffle 502, there is a pusher chute 504 for the pusher component 2 to push the material quickly and a pressing chute 505 for the tobacco box 10 to be pressed tightly. By adopting the design of multi-station independent modular sorting components 5, each sorting component 5 corresponds to a specific specification or type of tobacco box 10. The corresponding station can be accurately called to start, stop and operate independently according to order requirements, realizing the sorting of any combination of different series of cigarettes. There is no need to change tooling fixtures or adjust equipment parameters throughout the process, which greatly shortens the order changeover time and significantly improves the order response speed and sorting flexibility.

[0033] Furthermore, the feeding assembly 7 includes a partition 701 fixedly connected inside the top cavity 3. A second motor 702 is fixedly connected to one outer wall of the partition 701. A second threaded screw 704 is fixedly connected to the output end of the second motor 702. A second threaded sleeve 705 is threadedly connected to the outer circumference of the second threaded screw 704. A second through groove 706 is opened on the bottom inner wall of the top cavity 3. A slide plate 707 is fixedly connected to the bottom outer wall of the second threaded sleeve 705. One end of the slide plate 707 passes through the inside of the second through groove 706. A second baffle 8 is fixedly connected to the bottom inner wall of the storage box 4 to facilitate accurate feeding by the feeding assembly 7. One end of the slide plate 707... A fixing plate 708 is fixedly connected to the outer side wall. A second fixing seat 709 is fixedly connected to one side of the outer wall of the fixing plate 708. A third motor 710 is fixedly connected to one side of the outer wall of the second fixing seat 709. A third threaded screw 712 is fixedly connected to the output end of the third motor 710. A third threaded sleeve 711 is threadedly connected to the outer circumference of the third threaded screw 712. A horizontal column is fixedly connected to one side of the outer wall of the third threaded sleeve 711. A movable clamping plate 716 is fixedly connected to one end of the horizontal column away from the third threaded sleeve 711. A third guide post 714 is fixedly connected to one side of the outer wall of the other second fixing seat 709. The circular... A guide cylinder 715 is slidably connected to the outer wall of the periphery. A reinforcing column 713 is fixedly connected to the top outer wall of the guide cylinder 715. The end of the reinforcing column 713 away from the guide cylinder 715 is fixedly connected to the bottom outer wall of the third threaded sleeve 711. The bottom of the storage box 4 is provided with a feeding chute to facilitate the rapid falling of the tobacco box 10 into the sorting box 501. When the sorting component 5 is working, the tobacco box 10 pre-stored in the corresponding storage box 4 falls into the sorting box 501 below through the bottom feeding chute. When the material in the storage box 4 is insufficient, the feeding component 7 inside the top cavity 3 automatically starts the replenishment process, that is, the second motor 702 drives the second threaded screw 704 to rotate. The second threaded sleeve 705 and the slide plate 707 move horizontally along the second through groove 706 to the material picking position. The third motor 710 then drives the third threaded screw 712 to rotate, causing the third threaded sleeve 711 to move the movable clamping plate 716 towards the fixed clamping plate 708 to clamp the tobacco box 10. The cooperation between the guide cylinder 715 and the third guide column 714 ensures the stability of the clamping plate movement and prevents the tobacco box 10 from falling or tilting during the transfer process. After the slide plate 707 moves the clamped tobacco box 10 to above the storage box 4, the movable clamping plate 716 releases to complete the material replenishment. The entire process of automatic material replenishment does not require manual intervention and significantly improves the continuous operation time of the equipment.

[0034] Furthermore, the top of the first vertical rod 223 is provided with a ramp surface 224, which can cooperate with the protrusion 222 when the pusher assembly 2 is reset, so that it can be stably lifted and reset. A second guide post 221 is fixedly connected to one side of the outer wall of the first vertical rod 223. The other end of the second guide post 221 passes through one side of the second vertical rod 235. A second spring 220 is sleeved on the circumferential outer wall of the second guide post 221.

[0035] Furthermore, the pushing assembly 2 includes a housing 201 and a support frame 202. A first fixed seat 203 is fixedly connected to the top outer wall of the housing 201. A first groove 218 is formed on the top of the first fixed seat 203. A sliding seat 212 is slidably connected inside the first groove 218. A second groove 219 is formed on the top outer wall of the sliding seat 212. A pushing plate 213 for pushing the tobacco boxes 10 inside the sorting box 501 onto the conveyor belt 1 is slidably connected inside the second groove 219. A second vertical rod 235 is fixedly connected to the top outer wall of the sliding seat 212. A first vertical rod 223 is fixedly connected to the top outer wall of the pushing plate 213. A first vertical plate 204 is fixedly connected to the top outer wall of 201. A first rotating column 205 is rotatably connected to one side outer wall of the first vertical plate 204. A swing rod 209 is fixedly connected to one end of the first rotating column 205. One end of the swing rod 209 contacts the top of the second vertical rod 235. A protrusion 222 is fixedly connected to the bottom outer wall of the swing rod 209. One side of the protrusion 222 contacts one side of the first vertical rod 223. When the pushing assembly 2 is started, the first motor 236 drives the second rotating column 226 to rotate. Through the meshing of the first gear disk 225 and the second rack 237, the sliding seat 212 moves along the first chute 218 toward the sorting box 501. As the sliding seat 212 moves, it can drive the pushing assembly on its top. The pusher plate 213 moves horizontally together. When the pusher plate 213 moves to the point where its top first vertical rod 223 abuts against the protrusion 222, the entire pusher plate 213 can no longer move horizontally. However, the sliding seat 212 will still move together with the second rack 237. During this process, the second spring 220 sleeved on the abutment plate 211 will gradually be compressed and stored. As the sliding seat 212 continues to move, the second vertical rod 235 will gradually approach the swing arm 209. When the top of the second vertical rod 235 is completely in contact with the end of the swing arm 209, the first motor 236 stops working. At this time, the second spring 220 is in a state of stored energy waiting to be released. When the sorting component 5 receives the shipment signal, the first motor 236 starts again to drive the sliding seat 212. The material continues to move at a constant speed along the first chute 218 toward the sorting box 501. At this time, the second vertical rod 235, which moves laterally, will push the swing rod 209 upward. After the swing rod 209 is pushed up, the protrusion 222 at the bottom of the swing rod 209 is no longer blocked by the first vertical rod 223. The second spring 220, which is in a compressed state, releases its elastic potential energy instantly, thereby pushing the first vertical rod 223 and the pusher plate 213 to be rapidly ejected and fed along the second chute 219 toward the discharge chute 503. At this time, the pusher plate 213 passes through the pusher groove 504 on the side wall of the sorting box 501 and pushes the tobacco box 10 at the bottom of the sorting box 501 from the discharge chute 503 onto the conveyor belt 1 with a stable and controllable impact force, thus completing the sorting and feeding of the tobacco box 10.

[0036] Furthermore, a first motor 236 is fixedly connected to one side of the outer wall of the housing 201, a second rotating column 226 is fixedly connected to the output end of the first motor 236, a first gear disk 225 is fixedly connected to the outer circumference of the second rotating column 226, a second rack 237 is meshed with the outer circumference of the first gear disk 225, and the second rack 237 is fixedly connected to one side of the outer wall of the sliding seat 212.

[0037] Furthermore, a fixed cylinder 206 is fixedly connected to the outer circumference of the first rotating column 205, and a first connecting plate 208 is fixedly connected to the outer circumference of the fixed cylinder 206. A first baffle 207 for swinging and limiting the first connecting plate 208 is fixedly connected to one side of the outer wall of the first vertical plate 204. The first baffle 207 on the first vertical plate 204 precisely limits the swing rod 209 by limiting the maximum swing angle of the first connecting plate 208, ensuring the consistency of each energy storage and material pushing stroke.

[0038] Furthermore, a second vertical plate 227 is fixedly connected to the inner top wall of the housing 201. One end of the second rotating column 226 is rotatably connected to the second vertical plate 227. A third rotating column 229 is rotatably connected to one side of the second vertical plate 227. A second gear disk 228 is fixedly connected to the outer circumference of the third rotating column 229. A first rack 216 is fixedly connected to the outer wall of the other side of the sliding seat 212. The first rack 216 meshes with the second gear disk 228. A groove that does not mesh with the second gear disk 228 is provided in the middle of the first rack 216. A first helical gear 230 is fixedly connected to the outer circumference of the third rotating column 229. A second helical gear 231 meshes with the outer circumference of the first helical gear 230. A first threaded screw 232 is fixedly connected to the inner circumference of the second helical gear 231. A first threaded sleeve 233 is threadedly connected to the outer circumference of the first threaded screw 232. A sliding column 234 is fixedly connected to one side of the outer wall of the first threaded sleeve 233. A first through groove 217 is opened on one side of the outer wall of the housing 201. One end of the sliding column 234 passes through the inside of the first through groove 217. While the second spring 220 is storing energy, the first rack 216 on the other side of the sliding seat 212 will also mesh with the second gear disk 228. When the second gear disk 228 rotates, it can drive the third rotating column 229 to rotate synchronously. Then the third rotating column 229 passes through the first helical gear 230 and the second helical gear 231. The vertical reversing transmission of 1 causes the first threaded screw 232 to rotate and drive the first threaded sleeve 233, the sliding column 234, and the L-shaped second connecting plate 210 to move towards the pressing groove 505. This allows the abutment plate 211 to pass through the pressing groove 505 and smoothly press the tobacco box 10 in the sorting box 501. Since the first rack 216 has a groove in the middle, after the first rack 216 moves laterally a certain distance (i.e., it has already pressed the tobacco box 10), as the first rack 216 continues to move laterally (i.e., the subsequent action of the second spring 220 storing energy), the abutment plate 211 will not continue to apply pressure to the tobacco box 10. This ensures reliable pre-positioning of the tobacco box 10 and avoids deformation of the tobacco box caused by excessive compression. To prevent issues like creases and even internal cigarette breakage, when the second spring 220 is in the energy storage and ready-to-release state, the abutment plate 211 has already pressed the second-to-last and third-to-last tobacco boxes 10 in the sorting box 501 together. This avoids the situation where the bottom tobacco box 10 cannot be pushed out stably and quickly due to the weight of the tobacco boxes 10 stacked above during the subsequent pushing process. When the first motor 236 starts again (i.e., the sorting component 5 receives the delivery signal), the rear half of the first rack 216 will mesh with the second gear disk 228 again, so that the second connecting plate 210 will apply pressure to the abutment plate 211 again. At this time, the buffering effect of the first spring 215 can prevent the tobacco box 10 from being damaged due to excessive pressure.

[0039] Furthermore, a second connecting plate 210 is fixedly connected to one end of the sliding column 234 that passes through the first through groove 217. The cross-section of the second connecting plate 210 is L-shaped. A stop plate 211 is provided on one side of the second connecting plate 210. A first guide post 214 is fixedly connected to the outer wall of one side of the stop plate 211. One end of the first guide post 214 passes through one side of the second connecting plate 210. A first spring 215 is sleeved on the outer circumference of the first guide post 214. The stop plate 211 is located on one side of the pressing groove 505. After the pushing action is completed, the first motor 236 immediately reverses and drives the sliding seat 212 to return to its original position along the first sliding groove 218. The swing rod 209 swings downward and returns to its original position under its own weight as the second vertical rod 235 moves backward. The first baffle 207 on the first vertical plate 204 limits the maximum swing angle of the first connecting plate 208 on the swing rod 212. 09. Precise positioning is performed to ensure consistency between each energy storage and pushing stroke. When the sliding seat 212 returns to the center of the toothless groove of the first rack 216 and aligns with the second gear disk 228, the abutment plate 211 stops moving and remains in a pressing state. This avoids the situation where the tobacco boxes 10 stacked above the sorting box 501 fall prematurely due to loss of clamping force during the resetting process of the pushing plate 213, pressing down on the front end of the pushing plate 213 and preventing it from resetting. When the sliding seat 212 continues to return to the front toothed section of the first rack 216 and re-meets with the second gear disk 228, the second gear disk 228 rotates in the opposite direction. Through the transmission of the helical gear and the threaded screw, the abutment plate 211 is driven to smoothly exit the clamping groove 505. The tobacco boxes 10 in the sorting box 501 automatically fall one grid under the action of gravity, completing automatic replacement and preparing for the next sorting operation.

[0040] In summary, with the help of the above-mentioned technical solution of the present invention, when the supply system issues a sorting instruction, since multiple sorting components 5 contain different series of cigarettes, and each sorting component 5 corresponds to a specific specification or category of tobacco box 10, the sorting component 5 at the corresponding workstation can be accurately called to work independently according to the order requirements, realizing the on-demand mixed sorting of multiple categories of cigarettes without changing tooling or adjusting equipment parameters, which greatly improves the order response speed and sorting flexibility. When the sorting component 5 is working, the tobacco box 10 pre-stored in the corresponding storage box 4 falls into the sorting box 501 below through the bottom feeding chute. When the material in the storage box 4 is insufficient, the feeding component 7 inside the top cavity 3 automatically starts the replenishment process. The second motor 702 drives the second threaded screw 704 to rotate, which in turn moves the second threaded sleeve 705 and the slide plate 707 horizontally along the second through groove 706 to the material picking position. The third motor 710 then drives the third threaded screw 712 to rotate, which causes the third threaded sleeve 711 to move the movable clamping plate 716 toward the fixed clamping plate 708 to clamp the tobacco box 10. The cooperation between the guide cylinder 715 and the third guide column 714 ensures the stability of the clamping plate movement and prevents the tobacco box 10 from falling or tilting during the transfer process. After the slide plate 707 moves the clamped tobacco box 10 above the storage box 4, the movable clamping plate 716 is released to complete the material replenishment. The entire process of automatic material replenishment does not require manual intervention and significantly improves the continuous operation time of the equipment. Subsequently, the pusher assembly 2 at the target sorting station is activated. The first motor 236 drives the second rotating column 226 to rotate. Through the meshing of the first gear disc 225 and the second rack 237, the sliding seat 212 moves along the first chute 218 toward the sorting box 501. As the sliding seat 212 moves, it can drive the pusher plate 213 on top of it to move horizontally together. When the pusher plate 213 moves to the point where the first vertical rod 223 on top of it abuts against the protrusion 222, the entire pusher plate 213 can no longer move horizontally, but the sliding seat 212 will still move along with the second rack 237. During this process, the second spring 220 sleeved on the abutment plate 211 will be gradually compressed and stored. As the sliding seat 212 continues to move, the second vertical rod 235 will gradually approach the swing arm 209. When the top of the second vertical rod 235 is completely in contact with the end of the swing arm 209, the first motor 236 stops working. At this time, the second spring 220 is in the energy storage and waiting state. When the sorting component 5 receives the shipment signal, the first motor 236 starts again and drives the sliding seat 212 to continue to move forward at a constant speed along the first slide 218 towards the sorting box 501. At this time, the horizontally moving second vertical rod 235 will push the swing rod 209 upward. When the swing rod 209 is pushed up, the protrusion 222 at the bottom of the swing rod 209 is no longer blocked by the first vertical rod 223. The second spring 220 in the compressed state releases elastic potential energy instantly, thereby pushing the first vertical rod 223 and the pusher plate 213 to be rapidly ejected and fed along the second slide 219 towards the discharge trough 503. At this time, the pusher plate 213 passes through the push trough 504 on the side wall of the sorting box 501 and pushes the tobacco box 10 at the bottom of the sorting box 501 from the discharge trough 503 onto the conveyor belt 1 with a stable and controllable impact force, thus completing the sorting and feeding of the tobacco box 10. While the second spring 220 is storing energy, the first rack 216 on the other side of the sliding seat 212 also meshes with the second gear disk 228. When the second gear disk 228 rotates, it can drive the third rotating column 229 to rotate synchronously. Then, the third rotating column 229 is driven by the vertical reversal of the first helical gear 230 and the second helical gear 231, causing the first threaded screw 232 to rotate and drive the first threaded sleeve 233, the sliding column 234 and the L-shaped second connecting plate 210 to move towards the pressing groove 505. This allows the abutment plate 211 to pass through the pressing groove 505 and smoothly press the tobacco box 10 in the sorting box 501. Since the first rack 216 has a groove in the middle, after the first rack 216 moves laterally a certain distance (i.e., it has pressed the tobacco box 10), as the first rack 216 continues to move laterally (i.e., the second spring 220 stores energy), the tobacco box 10 will be pressed further. The abutment plate 211 will not continue to apply pressure to the tobacco box 10, which ensures reliable pre-positioning of the tobacco box 10 and avoids the problem of deformation, wrinkles or even breakage of the internal cigarettes caused by excessive compression. When the second spring 220 is in the energy storage and release state, the abutment plate 211 has already pressed the second to last and third tobacco boxes 10 in the sorting box 501, thereby avoiding the situation where the bottom tobacco box 10 cannot be pushed out stably and quickly due to the gravity of the tobacco boxes 10 stacked above during the subsequent pushing process. When the first motor 236 starts again (that is, the sorting component 5 receives the delivery signal), the rear half of the first rack 216 will mesh with the second gear disk 228 again, so that the second connecting plate 210 will apply pressure to the abutment plate 211 again. At this time, the buffer of the first spring 215 can prevent the tobacco box 10 from being damaged due to excessive pressure. After the pushing action is completed, the first motor 236 immediately reverses to drive the sliding seat 212 to return to its original position along the first slide groove 218. The swing rod 209, under its own weight, swings downwards and returns to its original position as the second vertical rod 235 moves backward. The first baffle 207 on the first vertical plate 204 precisely limits the swing rod 209 by restricting the maximum swing angle of the first connecting plate 208, ensuring consistency between each energy storage and pushing stroke. When the sliding seat 212 returns to its original position, aligned with the toothless groove in the middle of the first rack 216 and the second gear disc 228, the abutment plate 211 stops moving and remains in a pressed state, thus enabling... To prevent the tobacco boxes 10 stacked above the sorting box 501 from falling prematurely due to loss of clamping force during the reset process of the pusher plate 213, thus preventing the pusher plate 213 from being reset, the sliding seat 212 continues to reset until the toothed section of the front end of the first rack 216 re-engages with the second gear disk 228. The second gear disk 228 rotates in the opposite direction, and through the transmission of the helical gear and the threaded screw, it drives the abutment plate 211 to smoothly exit the clamping groove 505. The tobacco boxes 10 in the sorting box 501 automatically fall one grid under the action of gravity, completing the automatic replacement and preparing for the next sorting operation.
