Cigarette packaging machine braking device and braking method

Abstract

The invention provides a cigarette packaging machine braking device and a braking method. The cigarette packaging machine braking device comprises a PLC control unit, a jigger unlocking unit and a main motor braking unit. The PLC control unit and the jigger unlocking unit are both connected to the main motor braking unit. The PLC control unit sends out a non-braking control signal to the main motor braking unit when a cigarette packaging machine is started, and the PLC control unit sends out a braking control signal to the main motor braking unit when the cigarette packaging machine is shut down. The jigger unlocking unit sends out a braking or non-braking control signal to the main motor braking unit based on manual operation, and the main motor braking unit controls a main motor of the cigarette packaging machine to be in a braking self-locking state or a non-braking unlocking state according to the received braking or non-braking control signal. According to the scheme of the cigarette packaging machine braking device and the braking method, the defects of double braking patterns of an existing cigarette packaging machine are overcome, the braking reliability of the cigarette packaging machine is improved, inferior-quality cigarette bags, equipment damage and other potential safety hazards are avoided, meanwhile, no friction braking exists, the energy consumption is reduced,and it does not need to manually adjust the torque.

Description

technical field [0001] The invention relates to the field of tobacco packaging equipment, in particular to a braking device and a braking method for a cigarette packaging machine, especially a braking device and a braking method for an FHZ cigarette carton packaging machine. Background technique [0002] FHZ Cigarette Carton Packing Machine is a hard carton packing machine produced by German company Smoomen, which is suitable for B1 soft pack unit. Its function is to pack small cigarette packs (20 sticks) into carton label paper Inside, and sealed with a plastic film with a pull wire, it is a cigarette packaging machinery that finally outputs finished cigarette rods. [0003] The FHZ carton cigarette packaging machine is different from the independent servo drive mode that appeared in recent years. It is driven by a traditional mechanical transmission system. The main motor drives the gear transmission and the cam transmission. The action sequence works. Because the FHZ ci...

Problems solved by technology

This is the braking scheme adopted by the FHZ cigarette carton packaging machine in the prior art. After long-term equipment use, it is found that the existing double braking mode of the FHZ cigarette carton packaging machine has the following defects: (1) in the shutdown operation , the packaging machine cannot stably stop at certain positions (when multiple cams are in the lifting or lowering positions at the same time, they cannot self-lock), the packaging machine will rotate by itself under external disturbance, and produce the following evil results: a. Push the entrance to pinch the cigarette pack and produce defective cigarette packs; b. damage expensive equipment parts (strip oil seal cutter); c. pinch the operator, posing safety hazards; (2) need to frequently adjust the brake of the auxiliary brake device Dynamic torque (according to the statistics, the average is 1.1 times / week, each time takes 20 minutes), which seriously affects the efficiency of equipment; (3) When adjusting the braking torque of the auxiliary braking device, waste products will inevitably be produced, resulting in increased consumption of auxiliary materials; ( 4) Regardless of whether the FHZ cigarette carton packaging machine is in normal operation or in the shutdown process, the auxiliary braking device always gives a braking torque to the main shaft, which increases the resistance when the equipment is running, and consumes more power under the same operating speed. The increase in power consumption will increase the manufacturing cost of the enterprise and cause energy waste to the society
