Description

Technical Field

[0001] This utility model relates to the field of assembly lines, and in particular to an automatic box stacking assembly line. Background Technology

[0002] With the development of home organization, boxes are needed to collect and store miscellaneous items. To meet the needs of home organization, manufacturers produce various boxes of different sizes. Each box consists of a body and a lid. After production, the body and lid need to be stacked to reduce space. Traditionally, the stacking of the body and lid is done manually. Workers are surrounded by boxes of different sizes. They take out boxes of various sizes one by one and stack them from largest to smallest and from lowest to highest to reduce the floor space. The manual stacking method has the problems of low stacking efficiency, high labor intensity for workers, and high labor costs for enterprises. It cannot meet the needs of rapid industrial production. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic box stacking and assembly line.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The automatic box stacking and assembly line includes a stacking conveyor line for conveying box groups. At one end of the stacking conveyor line, several box-feeding machines are respectively provided on the side for providing box bodies. These box-feeding machines sequentially stack box bodies of decreasing size along the conveying direction of the stacking conveyor line to form box body groups. At the middle side of the stacking conveyor line, a lid-feeding and installing machine is provided. This machine conveys the largest-sized lid to the stacking conveyor line and installs the largest-sized lid onto the largest-sized box body on the stacking conveyor line. At the other end of the stacking conveyor line, several lid-feeding machines are respectively provided on the side for providing lids. These lid-feeding machines sequentially stack lids of decreasing size on top of the box body groups already stacked on the stacking conveyor line to form box groups.

[0005] By adopting the above technical solution, it not only realizes the automatic feeding and conveying of box bodies and the automatic stacking of box bodies from largest to smallest and from lowest to highest, but also realizes the automatic feeding and conveying of box lids and the automatic assembly of the largest box body and the largest box lid. It enables each box lid to be stacked on the largest box lid in a manner from largest to smallest and from lowest to highest. Moreover, the stacking process of box bodies and box lids is fully automated, requiring no manual intervention, which greatly reduces the labor intensity of workers and the labor costs of enterprises. It is suitable for stacking box bodies and box lids of different sizes, giving it the advantages of high stacking efficiency, neat stacking, good stacking effect, and strong versatility. It effectively solves the problems of low stacking efficiency, low degree of automation, high labor intensity of workers, and high labor costs of enterprises caused by the traditional manual stacking of box bodies and box lids.

Each box loading machine on the side of the stacking conveyor line stacks the box in descending order of size along the conveying direction of the stacking conveyor line. Several boxes are stacked in descending order of size and from low to high (i.e., forming a box group) on the stacking conveyor line. The stacked box groups are then conveyed on the stacking conveyor line.

The worm gear reducer 14 is connected to the belt conveyor line 12 via a chain and sprocket transmission assembly 15. In this embodiment, the belt drive device 13 is configured as a servo motor.

[0081] Reference Figures 1 to 14 As shown, the working principle of the automatic box stacking assembly line is as follows: the box body is fed and conveyed by the first circulating feeding mechanism 6 of each box body feeding machine 2. The first circulating feeding mechanism 6 places the box body on the transfer device 62 on the end of the annular double track 61 away from the first conveying mechanism 7 to prepare the box body. The chain drive device 633 drives the chain 635 for transmission. The chain 635 is connected to a transfer device 62 through a mounting part 637 so that it can drive multiple transfer devices 62 to circulate on the annular double track 61 to transfer and feed the box body. When the chain drive mechanism 63 drives the transfer device 62 to move to the end of the annular double track 61 close to the first conveying mechanism 7, the output end of the limit drive device 65 extends and inserts into the transfer device 62 to block and limit it. The first camera mechanism 9 of each box loading machine 2 detects the position of the box body closest to it. The first suction head 76 of the first conveying mechanism 7 of each box loading machine 2 can pick up the box body from the end of the first circulating loading mechanism 6 closest to it and stack it on the stacking conveyor line 1 according to the detection result of the position of the box body by the first camera mechanism 9 and with the cooperation of the first Y-axis moving component 71, the first X-axis moving component 72 and the first Z-axis moving component 74. Several box loading machines 2 stack the boxes sequentially from low to high along the conveying direction of the stacking conveyor line 1. The conveyor line 1 stacks boxes in descending order of size, that is, several boxes are stacked in groups from large to small and from low to high on the stacking conveyor line 1. The stacked box groups are transported on the stacking conveyor line 1 in sequence. When the top box of the transfer device 62 closest to the first conveying mechanism 7 is sucked away by the first suction head 76 of the first conveying mechanism 7, the lifting drive device 64 lifts the box group on the transfer device 62, so that the top box of the remaining boxes (i.e., box groups) is always kept at the predetermined feeding height.

[0082] While the box body is being fed, the box lids are fed through the box lid feeding machines 4. The third cycle feeding mechanism 42 of each box lid feeding machine 4 feeds the box lids according to the same principle as the first cycle feeding mechanism 6 of the box body feeding machine 2. Among them, the box lid feeding and installation machine 3 feeds the largest size box lid to the stacking conveyor line 1 and installs the largest size box lid on the largest size box body conveyed on the stacking conveyor line 1. The second camera mechanism 35 of the box lid feeding and installation machine 3 performs swing direction detection on the topmost box lid at the end closest to it on the second cycle feeding mechanism 32. The third camera mechanism 36 of the box lid feeding and installation machine 3 monitors the box body assembly on the stacking conveyor line. The position of the lid is detected on the second conveying mechanism 33. The second suction head 3367 of the second conveying mechanism 33 picks up the largest size box lid from the end of the second circulating feeding mechanism 32 with the cooperation of the second Y-axis moving component 331, the second X-axis moving component 332 and the second Z-axis moving component 334. According to the sway detection result of the box lid by the second camera mechanism 35, the suction head rotation drive device 3366 drives it (i.e. the largest size box lid) to rotate to the angle corresponding to the assembly of the largest size box body, and then installs it on the largest size box body on the stacking conveyor line 1. This realizes the automatic assembly of the largest size box body and the largest size box lid. When the third cycle feeding mechanism 42 of each box lid feeder 4 conveys the box lid to the vicinity of the third conveying mechanism 43, the second box lid picking and rotating component 436 of the third conveying mechanism 43 of each box lid feeder 4 picks up the box lid from the third cycle feeding mechanism 42 and places it on the largest size box lid of the stacking conveyor line 1 for box lid stacking. The box lids are stacked from large to small and from low to high on the largest size box lid, and finally stacked on the stacking conveyor line 1 to form a box group.

[0083] Its overall structural design not only enables automatic feeding and conveying of the box body and automatic stacking of the box bodies from largest to smallest and from lowest to highest, but also automatically feeding and conveying the box lids and automatically installing the largest box body and the largest box lid. It allows all box lids to be stacked on top of the largest box lid in a manner from largest to smallest and from lowest to highest. The stacking process of the box body and lids is fully automated, requiring no manual intervention, which greatly reduces the labor intensity of workers and the labor costs of enterprises. It is suitable for stacking box bodies and lids of different sizes, giving it the advantages of high stacking efficiency, neat stacking, good stacking effect, and strong versatility. It effectively solves the problems of low stacking efficiency, low automation, high labor intensity, and high labor costs associated with traditional manual stacking of box bodies and lids.

All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
