Embodiment Construction

[0012] The invention adopts FM352-5 high-speed Boolean processor to control the action of the rejection valve, so as to complete the high-speed rejection of waste products in the production process. The specific interface control circuit such as figure 1 As shown, it is mainly composed of Siemens S7-300 series CPU315-2DP (PLC), FM352-5 high-speed Boolean processor, pulse encoder, and rejection valve.

[0013] There are three digital input interface signals output from the PLC to the FM352-5 high-speed Boolean processor: V-groove waste rejection signal (input terminal 7 of the FM352-5 high-speed Boolean processor), drum waste rejection signal (FM352-5 high-speed Boolean The input terminal 8 of the processor), sampling and rejecting the signal (the input terminal 8 of the FM352-5 high-speed Boolean processor).

[0014] The digital output interface signals of FM352-5 high-speed Boolean processor are three: V-type valve Y1H control signal (output terminal 11 of FM352-5 high-speed...

Abstract

The invention discloses a method for accurately controlling filter tip elimination for a high-speed filter tip forming machine. An FM352-5 high-speed Boolean processor is adopted to control the action of a ejecting valve; a PLC controls the operation of the high-speed filter tip forming machine, when needing to eliminate defective filter tips, the PLC outputs an elimination signal to the FM352-5 high-speed Boolean processor; the FM352-5 high-speed Boolean processor collects a pulse signal from a pulse coder, when an input end thereof receives the elimination signal from the PLC, the FM352-5 high-speed Boolean processor determines the position of the defective filter tips to be eliminated according to the output pulse number of the pulse coder, and opens and closes the eliminating valve at a set phase. The method can realize high speed elimination of waste products in the production course, ensures high quality of filter tips, and is applicable to high-speed filter tip forming machines in the cigarette industry.

Description

technical field [0001] The invention relates to a method for precisely controlling filter rod removal of a high-speed filter rod forming machine in the cigarette industry. Background technique [0002] At present, the maximum speed of the filter rod forming machine produced in China is 600 m / min or 5000 pieces / min. The correct and quick removal of waste products during the production process ensures the high quality of the filter rods. The speed of 5000 pieces / minute means that the time for each filter rod to pass through the reject outlet is 12ms. How to complete the opening and closing of the reject valve in such a short time has become a subject. [0003] The process control of the high-speed filter rod forming machine adopts Siemens S7-300 series PLC (programmable logic controller). Control of the reject valve. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for precisely controlling the filter ro...
