Description

Thread selection control device of weaving loom multicolor weft {WEFT CONTROLLING DEVICE FOR USING WEFT AS WARP IN A STRAP WEAVING MACHINE}

The present invention relates to a thread selection control device of a loom multi-color weft, to install a plurality of control motors on the loom, to install a plurality of weft control levers on the body side of the loom, and to weft control levers of different colors By controlling the weft and moving the weft control lever up and down with the control motor, we select the weft of a specific color to move the weft to the predetermined position by this motor so that the worker can work conveniently.

The loom weaves warp and weft yarns in a weaving manner to weave long woven fabrics. The looms come in various forms depending on the different designs of the loom manufacturers or the different needs of different products. Fabrics made by conventional looms are usually simple long-shaped fabrics or different colored warp or weft yarns can be used to make different products. If warp yarns of different colors are used, fabrics containing stripes of different colors are woven, and when weft yarns of different colors are blended, the lattice fabric is woven, thereby producing more beautiful textile products.

In the current technology, weft conversion is a very difficult task. Some manufacturers use specific yarns from the warp to weft, but this method requires the use of a repeating operation chain combined with a faceplate when using traditional looms. ), This control chain must be 120 nodes, and at the selected position, the face plate must be driven by the chain of this node to select the conversion chamber. This is very inconvenient for work as personnel have to change the coupling model of the operation chain very cumbersomely. In addition, in this design, when the operation chain is set up, only the set model can be cycled, and no change can be made, so that different changes can not be increased in each cycle. In addition, when fabric designers require hundreds of needles each time, the design and placement of such a working chain can be difficult to imagine.

Some other manufacturers change wefts by pulling them out. In other words, we form several different colors of weft yarns on the body side of the loom and select the weft yarn with a suitable tool. This operation method is a problem in the processing of the clue of the weft yarn. When we replace the weft each time two clues (頭尾) is formed, so if left on the surface of the fabric as it will necessarily affect the appearance and texture of the product is a difficult problem to solve easily. There is currently a method of weaving with heat-melting wefts. This thermal melting method is a method of applying heat to a clue exposed to the surface of the fabric so that it is contracted into the fabric and concealed on the surface of the fabric by the cohesion generated when the yarn is dissolved. Since the thread conversion work must be synchronized with the warp operation of the loom, it cannot be effectively simplified in the arrangement of the machine, and there are problems such as heating equipment and heating temperature control when treating the clues by the heat melting method. It became.

The main object of the present invention is to provide a thread selection control device of the loom multi-color weft, to install a plurality of control motors on the loom, to install a plurality of weft control levers on the body side of the loom, each control motor One weft control lever is operated with a control thread, and each weft control lever has a weft hole through which the weft thread can pass through, and weft control lever is moved up and down to the control thread through the control of the motor to select a weft of a specific color. The control motor moves the weft to the intended position to make the selection of the thread convenient.

The second object of the present invention is that each control motor can be synchronized with the warp control structure of the loom, so that the weft can be synchronized with the warp even when the weft is not used. It is to provide a room selection control device.

The third object of the present invention is that each control motor is controlled through a computer or a suitable control device, so that the setting model can be easily switched, and various models of the fabric can be set very simply, and the variation of the model is very diverse. It is possible to provide a thread selection control device of a loom multicolor weft which can be achieved and which can weave a variety of textile products without being restricted by machine structure.

One end of the) is connected, the other end of the elastic member 222 is fixed to the assembly plate 10, the assembly plate 10 is further provided with a plurality of auxiliary spool (spool) (24) have.

Each of the operating levers 26 hangs on the thread hanger grooves 220 of the operating levers 22, which extend through the corresponding auxiliary spool 24 and extend out of the assembly plate 10. The control chamber 30 is connected to the end of each operation chamber 26 extended outside the assembly plate 10, and the number of the control chambers 30 connected to the end of each operation chamber 26 operates the loom. It depends on the number of fabrics produced. That is, each control chamber 30 connected to the end of each operating chamber 26 extends to the side of the loom, respectively, so that the weft yarn selected by each loom is synchronized. The connection of the operation chamber 26 and the control chamber 30 may adopt a method which is widely used at present, and this connection method is a well-known prior art and various descriptions thereof will be omitted.

As shown in FIG. 3, the control chamber 30 operated by the different control motor 20 extends downwardly vertically after passing through the respective thread guide holes 320 on the thread guide plate 32, respectively. The lower end of each control chamber 30 is connected to the upper end of the weft control lever 40, respectively, and the lower end of the control lever 40 is fixed to a position where weft threads of the body (not shown) side of the loom are to be installed.

An upper end of each control lever 40 is an integrally formed guide lever 400, and a lower end of the control lever 40 is formed with a weft hole 402 through which wefts can be installed, and each control lever 40 is formed on the guide plate 42. It is installed between the guide hole 420 and the control hole 460 formed on the control plate 46, the control motor 20 can move up and down through the operation chamber 26 and the control chamber 30, The position return spring 44 is provided in the guide lever 400 of this control lever 40, and the upper end of this position return spring 44 contacts the bottom face of this guide plate 42, and this control lever 40 is When the position return spring 44 is compressed and the control chamber 30 is loosened when moving upward due to the control chamber 30, the control lever 40 returns to the original position due to the position return spring 44. . Therefore, the control lever 40 can be moved up and down due to the control motor and the position return spring 44.

As can be seen from the embodiment shown in Figs. 1 to 3, since the four control motors 20 are installed in the assembly plate 10, the four operation chambers 26 can be accompanied. In addition, six seal guide holes 320 are formed in the seal guide plate 32, but only four control chambers 30 are provided through the seal guide plate 32, and six guide holes 420 are formed in the guide plate 42. In addition, six control holes 460 are formed in the control plate 46, but there are only four control levers 40 installed therebetween. In other words, four wefts adopted in this embodiment can be added to the control motor 20 according to the actual demand and control more wefts together with the operation chamber 26, the control chamber 30 and the control lever 40. have.
