Weight control sampling synchrodyne circuit of cigarette making machine

Abstract

The invention relates to a cigarette making machine weight control sampling synchronous circuit, wherein the multiple clock pulse (MCP) signal of an assembler is output to a pulse counting circuit as the clock of a counter after the isolation of a signal input circuit and level switch; the counting signal of the pulse counting circuit is output to a synchronous setting circuit; the sampling pulse SAMP_IN signal of a cigarette making machine is output to a sampling holding circuit after the isolation of the signal input circuit and level switch; the outputs of the sampling holding circuit and the synchronous setting circuit are connected with a signal output circuit via a logical operation circuit; moreover, after the isolation of the signal input circuit and level switch, the double long-cigarette pulse (DCP) signal of the assembler is respectively connected with the pulse counting circuit and the sampling holding circuit as a reset signal. The invention has the advantages that: the invention ensures the accuracy of high-speed sampling of cigarettes; meanwhile, with less investment, the invention omits the expensive expense cost to replace a plurality of drive parts in order to restore the function and the maintenance costs of frequent daily maintenance.

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
