(4) Material separation
1) The material box slides to the tail end of the conveying roller way under the action of the gravity of the material box;
2) when the second sensor 404 senses that a material box is arranged on the material reversing mechanism 4, the second limiting rod 301 is driven by the limiting cylinder to lift upwards to jack the front end of the material box to prevent the material box from sliding continuously, and meanwhile, the second limiting rod is separated from an adjacent material box on the material reversing mechanism 4 to prevent the adjacent material box from reversing;
3) when the first sensor 402 senses that the material pulling rod 401 returns to the original position, the second limiting rod is driven by the limiting cylinder to descend to the original position, and the material box slides from the conveying roller way 302 to the reversing mechanism 403 of the material reversing mechanism.
(5) Material reversing
1) When the third sensor 501 senses that a cache vacancy exists on the material taking table 5, the material pulling cylinder 502 drives the material pulling rod 401 to push the material box to the cache vacancy;
2) after the material box reaches the cache vacancy on the material taking table 5, the material pulling cylinder 502 drives the material pulling rod 401 to return to the original position;
3) after the pulling rod 401 returns to the original position, the first sensor 402 is triggered.
(6) Material buffer memory
1) After the material box reaches the buffer vacancy, sliding to each assembly point for temporary storage;
2) after an operator takes and assembles materials, an empty material box is placed on a material taking roller way of a material taking table;
3) the empty material box is conveyed back to the material sending area to wait for the next material sending.
