Problems solved by technology

[0005] In order to solve the problem that the traditional fixed-length weft feeder control system uses an asynchronous frequency conversion motor to drive, the acceleration and deceleration speed is slow, the weft insertion rate is low, and the volume is large, the structure is complicated, and the installation is more troublesome, resulting in the speed of the loom. In order to solve problems such as affecting production efficiency, the invention discloses a loom fixed-length weft feeder control system and a control method using the control system to achieve faster acceleration and deceleration, higher rotational speed, smaller volume, and easy installation and use. , the purpose of higher production efficiency

Embodiment 1

[0030] Such as figure 1 , 2 As shown, a fixed-length weft feeder control system, the control system includes at least one set of weft feeder control devices, the weft feeder control device includes a weft feeder controller, a weft storage motor electrically connected to the weft feeder controller , a yarn stopper and a detector for real-time monitoring of loom operating conditions, and the controller of the weft feeder is electrically connected to the main control board of the loom.

[0031] The weft storage motor is used to control the operation of the weft feeder. The weft storage motor is a high-speed AC servo motor. The high-speed AC servo motor has the characteristics of fast acceleration and deceleration, high speed, small size, easy installation and use, and energy saving and power saving. The production efficiency is greatly improved, and the cost of production and use is reduced.

[0032] The yarn stopper is used to adjust the tension of the yarn to avoid the phenom...

Embodiment 2

[0044] The rest is the same as that of Embodiment 1, except that multiple weft feeder control devices share the bus. The power supply method of multiple weft feeder control devices sharing the bus is more energy-saving and power-saving, and the production and use costs are reduced.

Embodiment 3

[0046] The rest are the same as those in Embodiment 1 or 2, except that the digital signal processing module is a 2808DSP chip. The use of 2808DSP chip makes the response speed of the control system faster, which improves the speed and precision of the entire control system. Under the condition of high-speed weft insertion, the violent fluctuation of weft insertion tension is avoided, and the tension of each weft yarn introduced into the shed remains uniform. So as to reduce weft insertion breakage and improve the quality of fabric.

Abstract

The invention discloses a fixed-length weft accumulator control system which comprises at least one group of weft accumulator control devices. Each weft accumulator control device comprises a weft accumulator controller, a weft accumulating motor, a yarn stopper and a detector, wherein the weft accumulating motor is electrically connected with the weft accumulator controller, the detector is used for monitoring operation state of a weaving machine in real time, an input device is further disposed on the weft accumulator controller which is electrically connected with a master control board of the weaving machine, and the weft accumulating motor is a high-speed alternating-current servo motor. By using the high-speed alternating-current servo motor for driving, speed increasing and reducing are fast, rotation speed of the weft accumulating motor is high, and filling rate is increased evidently. In addition, the fixed-length weft accumulator control system is small in size and convenient to mount and use, and production efficiency is increased effectively.

Description

technical field [0001] The invention relates to a weft feeder of a loom, in particular to a control system of a fixed-length weft feeder of a loom and a control method using the control system. Background technique [0002] The fixed-length weft feeder for jet loom is an important part of the jet loom (including water jet, air jet) system. The main functions of the weft feeder are to store the weft yarn, balance the tension and fix the length of the weft yarn. [0003] Most of the control systems of fixed-length weft feeders in domestic traditional jet looms are driven by asynchronous frequency conversion motors. It is more troublesome, and eventually the speed of the loom cannot be increased, which affects production efficiency. [0004] Therefore, a fixed-length weft feeder control system with fast acceleration and deceleration, high rotating speed, small volume, easy installation and use, and high production efficiency needs to appear urgently.
