Method, device and system for detecting horizontal smoke in cigarette conveying channel

Abstract

The invention discloses a transverse cigarette detection method, device and system for a cigarette conveying channel. The method comprises the steps that distance signals measured by a plurality of laser displacement detectors are obtained, specifically, the distance signals are the distances between the laser displacement detectors and cigarettes, the multiple laser displacement detectors are fixed to the upper portion of the cigarette conveying channel and arranged into a straight line perpendicular to the conveying direction of the cigarettes, and the multiple laser displacement detectors are the same in height; a pulse signal output by an incremental encoder is obtained, and a rotary shaft of the incremental encoder is connected with the axis of a belt pulley of the cigarette conveying channel; and whether transverse cigarettes exist in the cigarette conveying channel or not is determined according to the distance signals and the pulse signal. According to the transverse cigarette detection method, device and system for the cigarette conveying channel, detection of the transverse cigarettes in the cigarette conveying channel is achieved, the transverse cigarettes in the cigarette conveying channel can be found in time, accordingly, the workload of operators is decreased, and the equipment operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of automatic control of tobacco, in particular to a method, device and system for detecting horizontal smoke in a cigarette conveying channel. Background technique [0002] The cigarettes produced by the cigarette rolling machine pass through figure 1 and figure 2 The shown device is conveyed to the packaging machine: the pulley 1 driven by the motor drives the belt 2 through friction, and the belt 2 drives the cigarette stick 3 through friction. [0003] Under normal circumstances, the placement direction of the cigarettes 3 (the direction where the head and tail of the cigarettes are connected) and the running direction are perpendicular to each other, so as to ensure that the cigarettes 3 will not be blocked after entering the packaging machine. [0004] like image 3 , the horizontal cigarette 4 will appear during the cigarette conveying process, and the placement direction and running direction of the horizon...

AI Technical Summary

Problems solved by technology

[0004] like image 3 , the horizontal cigarette 4 will appear during the cigarette conveying process, and the placement direction and running direction of the horizontal cigarette 4 are no longer vertical. If the horizontal cigarette 4 enters the packaging machine, it is easy to block the cigarette storage of the packaging machine and cause the Downtime, it takes a long time to deal with the blockage of cigarettes in the packaging machine, which reduces the operating efficiency of the equipment

[0005] In order to reduce the number of shutdowns of the packaging machine caused by the horizontal smoke 4, the current method of strengthening self-inspection can only be adopted. When the horizontal smoke 4 is found on the cigarette conveying channel, the horizontal smoke 4 will be taken out in time. This method not only requires a lot of work , and because it is impossible for the operator to keep an eye on the cigarette conveying channel all the time, it is impossible to completely avoid the shutdown of the packaging machine caused by the horizontal smoke
