Weight control sampling synchrodyne circuit of cigarette making machine

Abstract

The invention relates to a cigarette machine weight control sampling synchronous circuit, the multi-clock pulse MCP signal of the machine is output to the pulse counting circuit as the clock of the counter after isolation and level conversion of the signal input circuit, and the counting signal of the pulse counting circuit is output to Synchronous setting circuit, the sampling pulse SAMP_IN signal of the cigarette making machine is output to the sample and hold circuit after isolation and level conversion of the signal input circuit, the output of the sample and hold circuit and the synchronous setting circuit are connected to the signal output circuit after a logic operation circuit, After isolation and level conversion of the signal input circuit, the double long cigarette pulse DCP signal of the plug-in machine is connected with the pulse counting circuit and the sample and hold circuit respectively as a reset signal. The invention has the advantages that the accuracy of high-speed sampling of cigarettes is guaranteed, the investment is small, and the expensive cost of replacing a large number of transmission parts and the maintenance cost of frequent daily maintenance are avoided for repairing this function.

Description

technical field [0001] The invention relates to the relevant technical field of control circuits of tobacco production machinery, in particular to a synchronization circuit for weight control and sampling of cigarette making machines. Background technique [0002] In the tobacco industry, the existing PROTOS70 crimping unit has insufficient inherent design performance, equipment aging and excessive decline, so that the weight control sampling of the current PROTOS70 unit cannot be performed or can only be sampled at a reduced speed. There are two main reasons: [0003] 1) Insufficient design: PROTOS70 weight control sampling synchronous signal is taken from the shaft encoder on the cigarette maker (SE70), and the sampling solenoid valve that performs sampling removal is located at the sampling wheel of the tipping machine (MAX70), between the two The distance is long, and there are many intermediate transmission links, which will inevitably cause accumulated errors. affect...

Problems solved by technology

[0006] The purpose of the present invention is to provide a synchronous circuit for weight control and sampling of cigarette makers, which solves the problem that the weight control and sampling of the existing crimpers cannot be performed after a certain number of years due to insufficient inherent design performance, equipment aging and excessive decline. Sampling can only be performed at a reduced speed, and the cigarettes taken out cannot reflect the actual production situation, affecting normal production
