A realization method of fabric automatic detection and tension automatic adjustment of flat knitting machine pulling device

Abstract

The invention discloses a method for realizing automatic fabric detection and tension automatic adjustment of a flat knitting machine pulling device. The fabric width between the flat knitting pulling devices is detected by an infrared device, and then the layer mode is automatically adjusted and adjusted through algorithm processing. pull. The present invention cooperates with the infrared emitting tube and the infrared receiving tube to detect whether there is fabric in the two sets of flat knitting machine pulling devices, so as to control the working state of the flat knitting machine pulling device, without the need to set up software, so that the degree of automation is higher. Through the feedback value of the infrared receiving tube of the sub-rake, the main control of the flat knitting machine obtains the current fabric width, thereby automatically adjusting the tension of each sub-rake, automatically changing the layer mode, reducing manual intervention, and avoiding human errors.

Description

technical field [0001] The invention relates to the field of drawing devices for flat knitting machines, and more specifically relates to a method for realizing automatic detection of fabrics and automatic adjustment of tension of the drawing device for flat knitting machines. Background technique [0002] There are a large number of pulling devices for fully formed computerized flat knitting machines. When weaving, most of the fabrics are not too wide to cover all the pulling devices of the flat knitting machine, so some pulling devices have no effect. The flat knitting machine drawing device that does not produce effect also just can not work. But how to judge which flat knitting machine pulling devices have no effect so as to control them to suspend work is a problem. [0003] With the machines currently on the market, how to determine which flat knitting machine pulling devices are not working and keep them in a standby state. Mainly use manual plate-making. When drawi...

AI Technical Summary

Problems solved by technology

However, this method is more complicated and is set in advance, and it is difficult to change according to the actual weaving fabric. Therefore, it is necessary to propose a method for realizing automatic fabric detection and tension automatic adjustment of the flat knitting machine pulling device. Detect whether there is fabric in the area of ​​the flat knitting machine pulling device, so as to accurately control the work of the flat knitting machine pulling device that needs to work
