Description

Technical Field

[0001] The present invention relates to the technical field of carton production and packaging, and particularly to a fully automatic intelligent carton board sorting and stacking machine. Background Art

[0002] In the current era of the booming global packaging industry, cartons, as indispensable packaging containers in the process of commodity transportation and sales, show a continuous and rapid growth in demand. From the prosperity of the e-commerce industry to the expansion of the manufacturing industry, from the circulation of food and beverages to the transportation of electronic products, cartons can be found everywhere. This huge market demand has promoted the rapid development of the carton production industry, and numerous carton production enterprises have emerged like mushrooms after a spring rain, with the production scale constantly expanding. However, in the carton production process, the sorting and stacking link of carton boards has become a bottleneck restricting the efficient development of the industry.

[0003] The instability of the traditional manual sorting and stacking method leads to frequent classification errors, and carton boards of different specifications and materials are mixed together. This not only brings great trouble to the subsequent packaging and transportation links, increases the additional sorting cost, but also may cause the carton boards to collapse and be damaged during transportation due to unstable stacking, resulting in waste of resources and economic losses. Moreover, it is difficult to ensure the neatness of manual stacking, and the carton boards occupy a large amount of space during storage and transportation, reducing the space utilization rate and increasing the enterprise's warehousing cost.

[0004] At present, although there are already some devices for carton board sorting and stacking on the market, most of these devices have different degrees of limitations. Some devices can only achieve simple classification functions, with limited recognition ability for carton boards of different specifications and materials, and cannot meet the diverse production needs. Moreover, the stacking accuracy of these devices is not high, the stacking is not neat, and it is easy to cause damage to carton boards. The automation degree of some devices is relatively low, and a large amount of manual auxiliary operations are still required, which not only increases the labor cost but also reduces the production efficiency.

[0025] During use, the roller conveyor 101 is controlled to start. When the roller conveyor 101 starts, it will convey the cardboard boxes to be palletized. When the cardboard boxes are being conveyed, the first drive motor 108 is controlled to start. When the first drive motor 108 starts, it will drive the first synchronous wheel 109 to rotate. When the first synchronous wheel 109 rotates, it will drive the second synchronous wheel 110 to rotate through synchronous belt transmission. When the second synchronous wheel 110 rotates, it will drive the synchronous shaft 111 to rotate. When the synchronous shaft 111 rotates, it will drive the third synchronous wheel 112 to rotate. When the third synchronous wheel 112 rotates, it will drive the fourth synchronous wheel 113 to rotate through synchronous belt transmission. When the fourth synchronous wheel 113 rotates, it will drive the first internal thread transmission tube 114 to rotate. And the outer surface threads of the two support screw rods 115 face in opposite directions, so that when the first internal thread transmission tube 114 rotates, it will drive the support screw rods 115 to move synchronously inward by the force generated by threaded connection. When the support screw rods 115 move synchronously inward, they will drive the push bar 106 to move linearly inward synchronously. When the push bar 106 moves linearly inward synchronously, it will push the cardboard boxes conveyed at the upper end of the roller conveyor 101 in a two-way centering manner. When the cardboard boxes are pushed to the centered position, the force on the push bar 106 will increase. When the pressure sensor 107 detects that the force on the push bar 106 increases, the first drive motor 108 is controlled to rotate in the reverse direction. When the first drive motor 108 rotates in the reverse direction, it will drive the push bar 106 to move linearly outward synchronously for reset, so that the push bar 106 can continuously push and center the cardboard boxes conveyed at the upper end of the roller conveyor 101 reciprocally; When the cardboard boxes are being conveyed centered at the upper end of the roller conveyor 101, the cardboard boxes will pass through the detection areas of the vision sensor 202 and the laser sensor 203. When the cardboard boxes pass through the detection area of the vision sensor 202, the vision sensor 202 will obtain the image information of the upper end of the cardboard boxes and identify the specifications, materials, and printing pattern features of the cardboard boxes. When the cardboard boxes pass through the detection area of the laser sensor 203, the laser sensor 203 emits laser beams to accurately measure the length, width, and height of both sides of the cardboard boxes. At the same time, the vision sensor 202 and the laser sensor 203 will transmit these data to the control system for analysis and processing, and judge and classify the category and size information of the cardboard boxes based on these data; When the control system judges and classifies the category and size information of the cardboard boxes, the first electric telescopic rod 304 is controlled to start. When the first electric telescopic rod 304 starts, it will drive the push plate 305 to move linearly outward. When the push plate 305 moves linearly outward, it will push the classified cardboard boxes linearly outward. When the classified cardboard boxes are pushed linearly outward, the classification slots 301 will classify and receive the cardboard boxes pushed outward, so that the unclassified cardboard boxes at the upper end of the roller conveyor 101 can continue to be conveyed forward; Meanwhile, after the cardboard boxes are classified and received by the classification slot 301, the second driving motor 405 is controlled to start. When the second driving motor 405 starts, it drives the transmission gear 406 to rotate. When the transmission gear 406 rotates, due to the meshing connection between the transmission gear 406 and the transmission rack 404, a force is generated to drive the moving vehicle 402 to move linearly outward along the outer curved surface of the third limiting slide bar 403. When the moving vehicle 402 moves linearly outward, it synchronously drives the stacking plate 412 to move linearly outward. When the stacking plate 412 moves linearly outward, the second infrared positioning sensor 415 and the first infrared positioning sensor 302 cooperate to vertically position the stacking plate 412. When the stacking plate 412 is vertically positioned with the classification slot 301, the third driving motor 408 is controlled to start. When the third driving motor 408 starts, it drives the transmission worm 409 to rotate. When the transmission worm 409 rotates, it meshes with and drives the transmission worm gear 410 to rotate. When the transmission worm gear 410 rotates, it drives the second internal thread transmission tube 407 to rotate. When the second internal thread transmission tube 407 rotates, due to the force generated by the threaded connection, the first lifting screw rod 411 moves linearly downward. When the first lifting screw rod 411 moves linearly downward, it drives the stacking plate 412 to move linearly downward. When the stacking plate 412 moves linearly downward, the negative pressure suction cup 414 is controlled to start. When the negative pressure suction cup 414 starts, it adsorbs the cardboard boxes at the upper end of the classification slot 301. When the negative pressure suction cup 414 adsorbs the cardboard boxes at the upper end of the classification slot 301, the third driving motor 408 is controlled to start to synchronously drive the stacking plate 412 to move linearly upward. When the stacking plate 412 moves linearly upward, it drives the cardboard boxes adsorbed by the negative pressure suction cup 414 to move linearly upward and be lifted, thus realizing the function of adsorbing and lifting the classified cardboard boxes; When the classified cardboard boxes are adsorbed and lifted, the second driving motor 405 is controlled to start to synchronously drive the stacking plate 412 to move linearly inward. When the stacking plate 412 moves linearly inward, it drives the adsorbed cardboard boxes to move linearly inward. When the adsorbed cardboard boxes move linearly inward, the second infrared positioning sensor 415 and the third infrared positioning sensor 509 cooperate to vertically position the stacking plate 412. When the stacking plate 412 is vertically positioned with the positioning frame 508, the third driving motor 408 is controlled to start to synchronously drive the cardboard boxes adsorbed by the negative pressure suction cup 414 to move linearly downward. When the cardboard boxes move linearly downward, the positioning frame 508 positions the cardboard boxes. When the positioning frame 508 positions the cardboard boxes, the negative pressure suction cup 414 is turned off. When the negative pressure suction cup 414 is turned off, the adsorbed cardboard boxes can be stacked on the upper end of the pallet 103, thus realizing the function of facilitating the classification and stacking of cardboard boxes; Meanwhile, when the positioning frame 508 positions the carton board, the fourth driving motor 501 is controlled to start. When the fourth driving motor 501 starts, it drives the first gear 502 to rotate. When the first gear 502 rotates, it meshes with and drives the second gear 503 to rotate. When the second gear 503 rotates, it drives the second lifting lead screw 504 to rotate. When the second lifting lead screw 504 rotates, the lifting arm 505 is driven to move linearly upward due to the force generated by the threaded connection. When the lifting arm 505 moves linearly upward, it synchronously drives the positioning frame 508 to gradually move upward. When the positioning frame 508 gradually moves upward, it gradually positions the continuously palletized carton boards, avoiding the deviation and displacement of the carton boards during continuous palletization.

[0026] The present invention can achieve continuous and efficient sorting and stacking operations, greatly shortening the production cycle, enabling the enterprise to produce more products in the same time, improving the production capacity and market competitiveness of the enterprise. It reduces the workload of manual sorting and stacking, liberating workers from heavy physical labor. At the same time, due to the efficient operation of the equipment, the enterprise can reduce the input of the number of workers, reduce the labor intensity and labor cost, and improve the economic benefits of the enterprise. Meanwhile, it reduces the problems of sorting errors and uneven stacking. It ensures the safety and stability of the carton boards during transportation and storage, improves the product quality, and enhances customer satisfaction.
