Description

  The present invention relates to a method and an apparatus for producing a non-sewn fabric such as clothes and bags by substantially non-sewing.

  Originally, when manufacturing garment clothing, bags, or industrial filter products, it is necessary to manually cut the fabric and material along the pattern and sew the cut fabric and material manually. It was. For this reason, it becomes a complicated process, and mass production by machines is difficult, and even if you want to make custom-made garments such as clothes, you have to wake up the pattern from what was measured on an individual order and apply the pattern to cut it. There was a tendency to spend too much time and money. Under such circumstances, there has been a strong demand for a non-sewing technique for producing textile garments, bags, or industrial filter products.

  Therefore, the present inventor has already proposed a technique for manufacturing a substantially non-sewn woven fabric that is sewed together with the weaving process and is completed as a garment only by cutting along the outline of the woven fabric. (Patent Document 1). This technique is devised so that the shuttle that transports the bobbin around which the swivel yarn is wound moves so as to move the swivel yarn as the weft (weft) according to the position of the warp (warp). Focusing on the use of wefts (wefts) unique to the region-specific swivel weaving technique, weaving the wefts (wefts) together along the outline of the shape of the bag, etc. in the process of weaving the fabrics, and weaving By cutting the outer shape line so as not to cut the weft (weft), it is possible to realize non-sewing of a finished fabric such as a bag.

2. Description of the Related Art Conventionally, an airbag or the like to be mounted on an automobile needs to be sewn with a sewing machine after weaving and sewing in order to reinforce a necessary strap or a portion where stress is concentrated when inflated.
In view of the above situation, an adhesive is applied to an appropriate width at the boundary between a multi-weaving portion and a single-weaving portion while weaving using a previously proposed method for producing a non-sewn fabric, or a sewing machine By moving other devices, such as devices, that are different from the loom device within the loom, the aim is to eliminate the sewing process to the reinforcement site that has been required so far.
That is, according to the present invention, an adhesive is applied to an appropriate width at the boundary between a multi-weaving portion and a single-weaving portion while weaving, or another device such as a sewing machine device different from the loom device is moved in the loom. Thus, a first object is to provide a method and an apparatus for manufacturing a non-sewn fabric capable of omitting the sewing process to the reinforcing portion.

Conventionally, when a swivel yarn as a weft (weft) is inserted, the swivel device is driven while the loom is driven (blank) without inserting a normal weft (weft). When the swivel device is driven during blanking, there is a problem that if there are many swivel parts, blanking increases and the production efficiency of the loom decreases.
In view of the above situation, the present invention provides a method and an apparatus for manufacturing a non-sewn fabric in which a normal weft (weft) and a swivel thread can be inserted simultaneously and a normal weft (weft) is always inserted. The purpose.

  In order to solve the above-described problem, the method for manufacturing a non-sewn fabric according to the first aspect of the present invention is such that the first woven structure of two or more layers is woven and at the same time does not form the first woven structure. In a method for producing a non-sewn fabric in which the first woven structure is sewn by a second woven structure different from the first woven structure formed while one or more wefts (wefts) are moved, the following (1 -1) to (1-4).

(1-1) A connecting portion that connects at least one layer of the first woven structure to one side surface of the woven fabric, the other at least one layer to the other side surface of the woven fabric, and connects the one side surface and the other side surface in a non-separable manner. The stitching position is instructed from the jacquard controller such that the second woven tissue sews the first woven tissue. (1-2) The above-described weaving / stitching step from the jacquard controller to obtain data of suture position, nozzle position control step of controlling positioning of the nozzles (1-3) nozzle injection step (1-4) that emits the adhesive from the nozzle to the suture site of the second weave the intended Cutting step to cut into shape

  According to the above configuration, since the adhesive can be injected in an appropriate width while weaving at the connecting portion that becomes the boundary between the portion to be woven multiple times and the portion to be woven once, the sewing process to the reinforcement site that has been necessary so far Can be omitted.

Jacquard refers to a device that controls the raising and lowering of all warps (warp yarns) one by one, and the jacquard controller refers to a device that controls jacquard. The jacquard is mounted on the loom device, and each warp (warp) set on the loom device is connected to each jacquard warp needle.
By using a jacquard, each time weft (weft) is woven, each warp (warp) arranged in parallel is instructed by the instructions from the jacquard, and is individually raised and lowered to become above the weft (weft). A warp (warp) under the warp (warp) and weft (weft) is made, and a woven fabric with a design pattern is woven. Recently, an electronic jacquard that uses an electronic signal for directly raising and lowering the vertical needle has been used.

  In the weaving / stitching step of (1-1), the stitching position is instructed from this jacquard controller, and the second weaving tissue stitches the first weaving tissue, and the boundary between the multiple weaving portion and the single weaving portion The connecting portion is formed by the second woven structure.

The nozzle is an apparatus that injects an adhesive and is another device different from the loom.
In the nozzle position control step (1-2) and the nozzle injection step (1-3), the position data of the stitched portion of the second woven tissue is obtained from the jacquard controller, and the nozzle positioning control is performed. Adhesive is injected into the suture site of the two woven tissues. The jacquard controller and the nozzle device are connected by, for example, a serial communication cable, and can pass stitch position data.
Specifically, the stitching position data obtained from the jacquard controller is the needle number of the jacquard vertical needle.

  In the cutting step (1-4), cutting is performed along the designed fabric shape to complete the fabric. Cutting may be manual or automatic. For example, a laser head equipped with a camera may be used to trace a black thread for a mark that has been temporarily sewn along the shape of the fabric and laser cut.

  The method for producing a non-sewn woven fabric according to the second aspect of the present invention includes at least one or more wefts that do not form the first woven structure at the same time that the first woven structure of two or more layers is woven. In the method for manufacturing a non-sewn fabric in which the first woven tissue is sewn by the second woven structure different from the first woven structure formed while the (weft) is moved, the following (2-1) to ( 2-4).

(2-1) A connecting portion that connects at least one layer of the first woven structure to one side surface of the woven fabric, the other at least one layer to the other side surface of the woven fabric, and connects the one side surface and the other side surface in a non-separable manner. The stitching position is instructed from the jacquard controller such that the second woven tissue sews the first woven tissue. (2-2) From the jacquard controller to obtain data of suture position, the needle position control step of controlling positioning of the sewing machine needle (2-3) the needle operation step (2-4) through a sewing needle suture site of the second weave the intended Cutting step to cut into shape

According to the above configuration, since it is possible to sew with a sewing machine to an appropriate width while weaving at the connecting portion that becomes the boundary between the portion to be woven multiple times and the portion to be woven once, the sewing process to the reinforcement portion that has been necessary so far is performed. It can be omitted.
Here, the sewing needle is a needle used for sewing with a sewing machine different from the loom.

  In the weaving / stitching step in the method for producing a non-sewn fabric according to the first aspect or the second aspect, the jacquard device controlled by the jacquard controller opens the warp (warp) by pulling it up in at least three stages. It is more preferable that the opening portion where the weft yarn (weft yarn) forming the second woven structure moves is different from the opening portion where the weft yarn (warp yarn) forming the first woven fabric moves.

By pulling and opening the warp (warp) in at least three stages, a normal weft (weft) and a swivel thread can be inserted simultaneously, and a normal weft (weft) can always be inserted. As a result, idle driving can be eliminated and the production efficiency of the loom can be improved.
Specifically, when the jacquard device raises and lowers each warp (warp yarn) one by one, the opening for raising and lowering is made up of three or more stages.
Here, opening in two stages means that there are two stages, that is, an unopened state and an opened state. In addition, opening in three stages means that there are three stages, that is, a state in which the opening is not performed, a normal opening state, and a state in which the opening is larger than usual (a level higher than usual).

  By making the lifting and lowering openings into three or more stages, a plurality of openings can be formed as viewed from the weft (weft) insertion direction, so that the normal weft (weft) and the second weave are different for each different opening. The wefts (wefts) constituting the tissue can be inserted simultaneously. When opening in two stages, it is necessary to insert the weft (weft) that constitutes the second woven structure while the loom is driven (blank) without inserting normal weft (weft). By making the section into three or more stages, it is possible to lose idle driving and improve the production efficiency of the loom.

  Specifically, the second woven structure is configured using a swivel weaving in which a swivel thread as a weft (weft) moves.

Next, the non-sewn fabric manufacturing apparatus of the present invention will be described.

  Here, the above-mentioned jacquard apparatus opens the warp (warp yarn) by pulling it in at least three stages, and forms the first weave structure and the opening where the weft (weft) forming the second weave structure moves. It is further preferable that the opening through which the weft (warp) moves is different.

  Specifically, the second woven structure is configured using a swivel weaving in which a swivel thread as a weft (weft) moves.

According to the present invention, it is possible to omit the sewing process to the reinforcing portion, and it is possible to improve the production efficiency of the loom and reduce the cost of manufacturing the fabric.
Also, normal wefts (wefts) and swivel yarns can be inserted at the same time, and normal wefts (wefts) can always be inserted, so that there is no idle driving and the production efficiency of the loom can be improved.

In the conventional fabric manufacturing flow, after a weaving process for weaving a fabric, a cutting process for cutting the fabric along a pattern is performed, and a fabric is completed through a sewing process for sewing the cut fabric.
On the other hand, in the method for producing a non-sewn fabric according to the present invention, simultaneously with the weaving step of weaving the fabric, wefts (wefts) are woven together along the outline of the shape of the target fabric (weaving + stitching). ). Then, the outline is cut so as not to cut the weft (weft) of the woven fabric (cutting step). When sewing is performed at the same time as weaving, an adhesive is applied along the outline of the shape of the target fabric, or sewing is performed with a sewing needle to complete the fabric without the sewing process.

A second woven structure forming device 4 for forming a second woven structure different from the first woven structure formed by moving at least one or more wefts (wefts) that do not form a structure; It consists of another device 7 that operates along the outline in the form of a fabric.

  The jacquard device 2 is arranged on the upper part of the loom 1 via the legs (6a, 6b) of the support 6. Each warp (warp) set on the loom 1 is connected to each warp needle of the jacquard device 2. Each time one weft (weft) is woven in the loom 1, the jacquard device 2 is in accordance with an instruction from the jacquard controller 3 (data signal S1), a thread 5, that is, one warp (warp) arranged in parallel. Raise and lower one piece alone.

Further, the second woven tissue formation device 4 is instructed by the jacquard controller 3 (data signal S2), weaves the second woven tissue, sews the first woven tissue of two layers to multiple layers, A connecting portion serving as a boundary between the multiple woven portion and the single woven portion is formed by the second woven structure.
Further, the other device 7 is instructed by the jacquard controller 3 to the stitching position, that is, the position of the connecting portion (data signal S3), and applies an adhesive along the outer shape line of the target fabric. Or, sewing with a sewing needle.

On the other hand, when the jacquard device opens the warp (warp) in three stages, the warp (warp) 56, 57, 58 is raised stepwise by the jacquard as shown in FIG. When viewed from (weft), two openings are made. In other words, opening in three stages includes a three-stage state that is a state in which the opening is not performed, a normal opening state, and a state in which the opening is larger than usual (up and down more than usual), thereby forming a second woven structure. The opening through which the swivel yarn 62 moves is different from the opening through which the normal weft (warp yarn) 61 forming the first woven structure moves.
Thus, by opening the warp (warp) in three stages, the normal weft (weft) 61 and the swivel thread 62 can be inserted simultaneously, and the normal weft (weft) 61 can always be inserted, Eliminating empty shots and improving loom production efficiency.
