Description

Technical Field

[0001] The invention belongs to the technical field of cigarette equipment, and in particular relates to a PB15 inlet cigarette packet channel fast switching device and method. Background Art

[0002] The PB15 cigarette pack storage is a buffer for storing and compensating cigarette packs between the small box packaging machine and the transparent paper packaging machine of the GDX6S unit, so as to balance the inconsistency of the operation of the two machines, optimize the production process, and improve the production efficiency of the line; at the same time, the "bypass" function of the equipment can be used to ensure the continued production of the equipment when the buffer fails. The PB15 cigarette pack storage is mainly composed of an inlet unit, an input paddle, a buffer, an output pulp, and an outlet unit. The inlet part receives the cigarette packs produced by the small box packaging machine, and the cigarette packs are placed in the buffer through the input paddle. The buffer runs in a cycle according to the first-in-first-out principle, passing the cigarette packs backwards. The output pulp extracts the cigarette packs from the buffer and puts them into the outlet unit, which is transmitted to the transparent paper packaging machine through the output belt. The entire system continues to operate at a speed that matches the upstream machine. When the PB15 cigarette pack storage fails, the inlet unit switches the cigarette pack conveying path so that the upstream and downstream machines are directly connected to achieve uninterrupted production. In the original control system, the PB15 cigarette pack storage device is in use by default, and the cigarette pack conversion device of the entrance unit is switched to the main conveyor belt. When the PB15 cigarette pack storage device fails, the upstream machine slows down to a stop state until the cigarette packs in the conversion channel are emptied and the conversion device is started. Then the upstream machine is increased to normal operating speed. If there is no fault in the conversion process, the entire process takes about 2 minutes. Moreover, after the PB15 cigarette pack storage device returns to normal and is put into use again, the same process is still required, and the conversion process is lengthy. Moreover, when the equipment is actually running, the conversion fails due to reasons such as the mismatch between the inlet conversion device and the cigarette pack conveyor belt and the slow action of the conversion cylinder, which causes the upstream and downstream machines to stop and wait for production to resume after the fault is resolved. The conversion time is longer, affecting the line operation efficiency. The main reasons why the PB15 cigarette pack storage device takes a long time to switch over are as follows: (1) The original control system relies on the upstream machine to slow down to zero and empty the cigarette packs in the conversion channel, which prolongs the conversion process time. (2) The original control system does not have a conversion channel emptying detection, so the cigarette pack is not completely emptied, causing the conversion channel to be blocked, which prolongs the conversion processing time and has low conversion reliability. For the above problems, the existing technology has not yet provided relevant solutions and technologies. Summary of the invention
