Box overturning method for strips

Abstract

The invention discloses a box overturning method for strips. If bags exist in strip boxes, the original position of a box overturning mechanism is 0 degree, after the strip boxes enter the box overturning mechanism, the box overturning mechanism is overturned by 180 degrees in the forward direction, stays for the preset time and then is rotated by 180 degrees in the reverse direction to return tothe original position, then the box overturning mechanism sends out the strip boxes and waits for the next strip box; and if no bags exist in the strip boxes, the strip boxes are allowed to enter thebox overturning mechanism no matter that the box overturning mechanism is in 0-degree position or the 180-degree position. If the strip boxes are bagged forwards (the bags exist in the strip boxes), box overturning is performed, air in the bags can be discharged, tobacco hardening and boxing compactness can be improved, later alcoholization of the strips is facilitated, and the quality of the strips can be improved; if the strip boxes are bagged reversely (no bags exist in the strip boxes), feeding and box overturning can be performed at 0 degree and 180 degrees, the box overturning mechanismis not required to return to the original position after box overturning, action waste does not exist, and mechanical wear and energy consumption are reduced.

Description

technical field [0001] The invention relates to the field of cigarette production, in particular to a box-turning method for cigarettes. Background technique [0002] Traditional process mode: After the cigarettes are packed, they are pre-pressed once, packed and compacted for the second time, bundled, microwave moisture and packing density are tested, and then enter the box-turning mechanism: 1. ), because the bagging mouth is upward, so do not turn over the box and go directly through the turning mechanism; 2. If the cigarette box is reversed (no bagging inside), the cigarette box enters the turning mechanism and must be turned over 180 degrees before exiting the box, and the turning mechanism Return to the starting position with an empty car, and then enter the next box. [0003] For the front cover (with bagging) process of the cigarette box, the bag inside the box is upward, so it is impossible to turn the box straight, because there is air in the bag, and after the to...

AI Technical Summary

Problems solved by technology

[0004] For the process of turning over the cigarette box (without bagging inside), this process will waste the action of turning the empty car back to the starting position every time the box is turned over, which will increase mechanical wear and energy consumption
