Description

Yarn monitoring system for automatic gun-punched carpet weaving machine

Technical Field

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

In the gun-punching process in the carpet production process, each yarn on a plurality of yarn drums is wound into a strand and is conveyed to a gun head of an electric weaving gun, and gun-punching processing of the carpet is completed on base cloth. This is called a broken yarn fault when any of several yarns is missing, resulting in a reduced number of tufts of yarn being implanted. In the gun-needling process, each yarn is likely to be exhausted, broken and other accidents in the using process, when the yarn breakage fault occurs, the electric weaving gun carries out flocking on the base cloth under the condition that the yarn is lacked, the pile number implanted into the base cloth is reduced, the surface density of the carpet is reduced, and defective products are generated; in addition, after the yarn breaks down, the operation of working a telephone switchboard needs to be carried out, in order to effectively ensure the quality of carpet weaving, the joint needs to be as small as possible, if the joint is too big, the pile head on the base cloth is obviously raised by a gun thorn, defective products can be caused, the joint is too big or even can not pass through a pinhole smoothly, the joint is blocked on a gun thorn needle head, the maintenance and the re-wiring threading are time-consuming and labor-consuming, and the production efficiency is greatly reduced.

In order to reduce the problem of carpet production quality caused by yarn breakage faults or overlarge joints as much as possible, operators are required to observe the yarn state constantly during gun-stabbing processing to ensure normal yarn conveying and further ensure the carpet production quality, but the manual monitoring not only causes great waste of human resources, but also has high cost. Therefore, the development of a yarn monitoring system for an automatic gun-punched carpet weaving machine not only has urgent research value, but also has good economic benefit and industrial application potential, which is the basis and the motivation for the invention to complete.

In addition, the yarn passes through the buffer box 23, and part of the yarn is positioned in the buffer box 23, so that the rewiring operation when the connector is overlarge is facilitated.

In this embodiment, the laser sensor 24 is installed on the mounting plate 9, the laser sensor 24 detects the tufting yarn at the position of the yarn inlet of the gun thorn box 8, identifies whether the tufting yarn exists or not, determines the yarn breaking fault of the tufting yarn, and if the laser sensor 24 detects that no tufting yarn passes, the yarn breaking fault occurs, and a signal is fed back to the controller to perform shutdown alarm.

As shown in fig. 8, the bottom of the control cabinet 3 is provided with locking universal wheels 301, which is convenient for the control cabinet 3 to move; the controller can be a conventional single chip microcomputer or a PLC controller sold in the market, the controller is respectively connected with the motors of the devices, the motors of the devices are controlled to act to realize the coordination and the coordination of the devices, the automatic gun-stabbed tufting processing is completed, and when a yarn fault occurs, the controller controls the motors of the devices to stop working, so that the machine-halt fault removal and treatment are realized.

The automatic carpet machine is woven to bayonet in this embodiment, the controller in the switch board 3 realizes the coordinated control to each part of whole machine, the automatic device 4 that contracts of the hanging of base cloth is realized and is tightened automatically to base cloth through the base cloth on base cloth stores pylon 1 and the stores pylon, the bayonet tufting on the base cloth is realized through the cooperation action of each device on bayonet frame 2, realize that automatic bayonet weaves the carpet, labour's effective substitution has not only been realized, and effectively avoided the row line width that artifical bayonet easily leads to, the fine hair is long, the problem of fine hair circle and tufting density non-uniformity, make the production efficiency and the production quality of tufting carpet improve greatly, tufting carpet quality has been promoted.

Based on foretell this automatic rifle thorn knits blanket machine yarn monitored control system, rotary encoder 20 can detect the 62 numbers of turns of rotation of pay off rack and record, and then judge the yarn use amount of yarn section of thick bamboo 25 on pay off rack 62, when the yarn is about to use up, warn in order to remind the staff to trade the line, broken yarn alarm 21 and visual sensor 22 can detect whether there is the yarn to take place the broken string trouble, and then effectively avoided because of the yarn lacks the pile quantity reduction of the implantation base cloth that leads to, prevent that carpet surface density reduces, the substandard product has been stopped and produced, cross line hole 2301 can judge the connector lug size, prevent that the too big carpet rifle thorn that leads to of yarn joint from weaving the unqualified phenomenon of quality and taking place, laser sensor 24 realizes the broken string fault detection of tufting knits the line.

Through this automatic yarn monitored control system for carpet machine is knitted to bayonet, the controller receives rotary encoder 20, broken yarn alarm 21, vision sensor 22, laser sensor 24 transmission signal, and output control signal, if detect that the yarn is about to run out, single yarn or tufting are knitted line broken line trouble, then each device motor stop work of controller control, alarm device 302 reports to the police, and show relevant trouble information on display screen 303, remind the staff to handle, need not manual monitoring, can weave the carpet in-process and detect the yarn condition automatically, carpet production quality has effectively been ensured, avoid the substandard product to produce.

It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should also be understood that various alterations, modifications and/or variations can be made to the present invention by those skilled in the art after reading the technical content of the present invention, and all such equivalents fall within the protective scope defined by the claims of the present application.
