Description

Technical Field

[0001] The present invention belongs to the technical field of packaging machinery, and in particular relates to a double-station high-efficiency carton packing system and a packing method. Background Art

[0002] In the carton packaging process of the cotton spinning industry, traditional cartoning machines generally operate in a single-station mode, equipped with a single yarn discharge station, a box packing station, and a gripper. The cartoning machine must sequentially complete the independent operations of "yarn discharge - box packing - divider placement - yarn discharge again - box packing again," resulting in low packing efficiency, often exceeding 60 seconds per box. For daily production exceeding 1,000 boxes, companies must install two separate packaging conveyor lines, which not only increases equipment costs but also increases the factory floor space by more than 50%. This also requires more operators, resulting in high labor costs.

[0003] Based on this, the present application proposes a dual-station high-efficiency carton packing system and packing method, which realizes the segmented arrangement of two layers of bobbin yarn in the carton through a main conveyor line and a double yarn pushing unit. The first row of yarn position units and the second row of yarn position units are respectively used for the packing operations of different layers of bobbin yarn in the carton. The packing efficiency is greatly improved by utilizing the sequential operation of the double packing positions and the synchronous overlapping execution of the corresponding operation steps in the first layer bobbin yarn packing operation and the second layer bobbin yarn packing operation.

A double-station efficient carton packing method, implemented based on the double-station efficient carton packing system according to any one of claims 1 to 9, characterized in that: The packing method includes packing operations of the first layer of bobbins and the second layer of bobbins; The packing operation of the first layer of bobbins comprises the following steps: Step 11: The main conveyor line delivers the bobbin yarn, and the first yarn pushing mechanism pushes the bobbin yarn to the first yarn row position. At the same time, an empty carton is placed on the first packing position, and the first gripper reaches above the first yarn row position. Step 12: The first gripper grabs the bobbin yarn on the first row of yarn positions and places it into the empty carton on the first packing position to complete the packing operation of the first layer of bobbin yarn, and then the first gripper is reset; Step 13, the carton loaded with the first layer of yarn moves along the roller conveyor line to the second packing position; The packing operation of the second layer of bobbin yarn comprises the following steps: Step 21: The main conveying line conveys the bobbin yarn, and the second yarn pushing mechanism pushes the bobbin yarn to the second yarn row position; Step 22: The partition gripper and the second gripper move together. The partition gripper grabs the partition and moves to above the second packing position. At this time, the second gripper reaches above the second row of yarns. Step 23: The partition gripper places the partition in the carton containing the first layer of yarn, then rises and resets. At the same time, the second gripper grabs the yarn on the second row of yarn. Then the partition gripper and the second gripper move together, and the second gripper places the grabbed bobbin into the carton on the second packing position to complete the packing operation of the second layer of bobbin yarn; After that, the partition gripper and the second gripper are reset, and the carton with two layers of bobbin yarn leaves the second row of yarn; The packing operation of the first layer of bobbin yarn in each carton is carried out in the order of steps 11 to 13, and the packing operation of the second layer of bobbin yarn is carried out in the order of steps 21 to 23; after step 11 in the packing operation of the first layer of bobbin yarn in the first carton is completed, step 21 is carried out synchronously with step 12, step 22 is carried out synchronously with step 13, step 23 in the packing operation of the second layer of bobbin yarn in the previous carton is carried out synchronously with step 11 in the packing operation of the first layer of bobbin yarn in the next carton, thereby realizing the continuous packing operation of double-layer bobbin yarn in double stations.
