Intelligent control board for electronic dobby device

Abstract

The intelligent control board for electronic dobby device is one control circuit for various kinds of shuttle loom in textile. It includes a switching power source circuit, a monitoring circuit, a sensor signal input isolating circuit, an RS-232 level converting circuit, a monolithic computer with peripheral circuit, a dobby electromagnet driving circuit, a weft selecting electromagnet driving circuit and an outer signal input circuit. It features a logic converting circuit connected between the sensor signal input isolating circuit and the monolithic computer with peripheral circuit, a memory circuit set between the monitoring circuit and the monolithic computer with peripheral circuit, and a loom interlinking output circuit connected to the monolithic computer with peripheral circuit. The present invention has the advantages of accurate control, reliable data storing, and reliable data transmission to avoid malfunction of loom.

Description

technical field [0001] The invention relates to an intelligent control panel for an electronic dobby device, which belongs to a control circuit and is used for various shuttleless looms in the textile field. Background technique [0002] Most of the various shuttleless looms in textile machinery use dobby devices (referred to as "dobby") to realize the heald lifting action and opening movement required in the weaving process, that is: the tissue signal designed according to the fabric pattern is controlled by the dobby device. Recognize and transform it into a heald lifting action, and after it is sent to the heald frame of the loom, the warp yarn is driven by the heald frame to form an up and down opening movement, thereby weaving various fabrics that meet the pattern requirements. The traditional mechanical dobby device with textured paper (or patterned board) as the input form of tissue signals can no longer meet the requirements for weaving complex patterns due to the di...

Problems solved by technology

However, the original control boards for electronic dobby generally only consider the use requirements of the electronic dobby itself, and simply realize the basic functions of storing and sending organizational data, the control function is not perfect, and due to the imperfect circuit design, making The control board lacks anti-interference ability in harsh situations, and data loss, transmission failure and even malfunction often occur during use, which affects the use effect of the electronic dobby and the performance of the shuttleless loom.
