Control device for selecting yarns among pleochroism weft yarns of ribbon loom

Abstract

A multi-color weft yarns selecting controller of ribbon loom is composed of multiple control motors and multiple weft yarn controlling rods with a hole at lower end for passing the weft yarn through it, and features that each of weft yarn controlling rods is controlled by relative control motor.

Description

technical field [0001] The invention relates to a multi-color weft yarn selection control device for a ribbon loom, which is provided with a plurality of control motors on the ribbon loom, and a plurality of weft yarn control rods are arranged on the reed side of the ribbon loom, and each weft yarn control rod To control the weft yarns of different colors, the control motor can drive the weft yarn control rod to move up and down, and when selecting a specific color weft yarn, the control motor can move the weft yarn to a specific position to provide convenience for the yarn selection operation. Background technique [0002] Ribbon looms mainly interweave warp yarns and weft yarns to weave long strips of cloth tapes. Based on the different design methods of ribbon loom manufacturers and the different needs of products, ribbon looms also have many different types; generally The tape woven by the most basic ribbon loom is only a simple "tape". When color changes are required, w...

Problems solved by technology

[0003] In the prior art, it has always been a very difficult job to change the weft yarn. Some manufacturers pull out specific threads from the warp yarn to make the weft yarn, but this operation must be done with a traditional weaving machine The repeating cycle operation chain is selected with a face plate. If there are 120 stitches in each change cycle, the operation chain needs to have 120 sections, and at the selected position, the chain is pushed against the face plate to select the thread change. , every time we want to change the weft yarn changing mode of the product, the operator must take great pains to change the matching mode of the operating chain, which is quite inconvenient in operation; and once the setting of the operating chain is completed, this design can only be used It is impossible to add any changes in between, and it is impossible to add some different changes in each cycle; in addition, if the number of stitches in each cycle required by the fabric designer exceeds several Hundreds of stitches, the design and arrangement of the operation chain will cause unimaginable difficulty

[0004] Other manufacturers change the weft yarn by pulling the weft yarn out, which is to pull multiple weft yarns of different colors on the reed side of the loom, and use an appropriate mechanism to select the weft yarn. The problems faced by this operation It is the treatment of the weft yarn end, because every time the weft yarn is replaced, two thread ends will be drawn. If it is exposed to the edge of the tape, it will inevitably damage the appearance and texture of the product, which is also a problem that is not easy to deal with; currently there is a The treatment method is to use heat-meltable weft yarns for weaving, and heat-melt the thread ends exposed on the edge of the tape by heat-melting, and use the cohesive force of the melted wire to shrink and hide in the edge of the tape. Although this kind of design can achieve the effect required by the design, but because the operation of changing the weft yarn must be synchronized with the operation of the warp yarn of the ribbon loom, the mechanism configuration cannot be effectively simplified, and when the thread end is processed by heat melting method, then It also faces problems such as heating equipment and heating temperature control, which are indeed issues that related industries need to solve urgently.
