Yarn monitoring system for automatic gun-tufted blanket weaving machine

Abstract

The invention belongs to the technical field of carpet production, and provides a yarn monitoring system for an automatic gun-tufted blanket weaving machine. The yarn monitoring system comprises a rotating encoder, yarn breakage alarms, a visual sensor, wire passing holes and a control cabinet. The rotating encoder is mounted at the bottom of a pay-off frame and is used for detecting the use amount of yarn spool yarns. The multiple yarn breakage alarms are arranged and mounted in pay-off hole positions of the pay-off frame and used for detecting the breakage of the yarns. The visual sensor ismounted between the pay-off frame and a wire collection hole and used for detecting the number of the winding yarns. The wire passing holes are located between the wire collection hole and a tractionwire feeder and used for detecting the joint size. A laser sensor is mounted outside a gun-tufted box and used for detecting the breakage of tufted threads. A controller connected with an inductor isarranged in the control cabinet. By the adoption of the yarn monitoring system, the yarn conditions that the yarn is used up, the yarn is broken and missed, and the thread connecting head is too largecan be detected automatically in the process of blanket weaving of a bayonet tufting machine, so that the carpet production quality is effectively ensured, and defective products are avoided.

Description

technical field [0001] The invention relates to the technical field of carpet production, in particular to a yarn monitoring system for an automatic gun-punched carpet weaving machine. Background technique [0002] In the stabbing process of the carpet production process, each yarn on multiple bobbins is wound into strands and delivered to the gun head of the electric weaving gun, and the stabbing process of the carpet is completed on the base fabric. When any one of several strands is missing, resulting in a reduced number of yarn tufts implanted, this is called a thread break failure. In the process of gun stabbing, each yarn may be exhausted or broken during use. When a broken thread occurs, the electric weaving gun will flock on the base fabric in the absence of yarn. If the number of piles entering the base fabric decreases, the density on the surface of the carpet will decrease, resulting in defective products; in addition, after the yarn breakage occurs, wiring opera...

Problems solved by technology

[0005] Specifically, the technical problem to be solved by the present invention is to provide a yarn monitoring system for an automatic gun-punched carpet weaving machine, so as to solve the problem that the yarn breakage cannot be automatically detected during the working process of the current gun-punched tufting machine, and The technical problem that the weaving quality of carpet gun stabbing is unqualified due to the large yarn splicing
