Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a folding and feeding device for a long fabric to a retention device.

(Prior art) In general, woven and braided long fabrics contain many so-called secondary impurities such as glues and oils during weaving, and if the fabric is made of natural fibers, there may be some impurities in addition to the pure fibers. , contains so-called primary impurities.

Therefore, in order to remove these impurities and bleach, a desizing process, a refining process, and a bleaching process are performed.

Since each step of desizing, refining, and bleaching takes time, the equipment used in this type of process is designed to lengthen the residence time of the fabric in the processing liquid in each step. As described in the publication, the plate-shaped folding devices disposed on both sides of the fabric are oscillated and the fabric fed at a constant speed is tightly folded into a "J" shaped box. It is known that the fabric is fed and gradually passed through a "J" shaped box by its own weight to lengthen the residence time so that the fabric can be sufficiently treated with the liquid during that time.

(Problems to be solved by the invention) In the plate-shaped folding device that tightly folds and stores the fabric in the “J”-shaped box described in the above publication, first, the fabric tends to stick to the plate-shaped folding device; There was a problem that "clogging" occurred in this part.

These problems are particularly noticeable when the fabric is pre-moisturized using a saturator or the like.

Additionally, when the fabric is tightly folded and stored in a "J"-shaped box without getting wet, the amount of penetration of the treatment liquid is different between the periphery and the center of the folded fabric. There was also the problem that it was prone to spots.

In addition, due to the weight of the tightly folded fabric,
There is also a problem in that the passing speed is not constant because it passes through the "J" shaped box, and processing unevenness is likely to occur due to the fast or slow passing speed.

Therefore, in order to solve these problems, the present applicant replaced the folding device in the above publication with a plate-shaped device and provided a liquid reservoir that sprays the processing liquid in the form of a liquid film. We previously proposed a method in which the fabric is folded by alternating the strength and weakness of the liquid.

However, with devices that fold the fabric by alternating the intensity of the treatment liquid sprayed from a liquid reservoir, it is extremely difficult to accurately control the injection intensity of the treatment liquid, making it difficult to fold the fabric accurately. There was a problem.

This invention was proposed in view of the above problems.
To provide a folding and feeding device for a long fabric to a retention device, which can continuously and accurately fold a long fabric without clogging, and can uniformly process the densely folded fabric without unevenness. This is a technical issue.

(Means for Solving the Problems) In order to achieve the above-mentioned technical problems, a folding and supplying device for a long fabric to a retention device of the present invention is formed in a loop shape and configured to be able to be driven to convey intermittently. Partition walls are erected at regular intervals on the outer peripheral surface of the conveyor to form fabric receiving recesses between the partition walls, and a long piece of fabric is continuously folded and stored in the fabric receiving recesses from above. A folding and supplying device for a long fabric to a retention device is provided with a treatment liquid spraying section that sprays a treatment liquid diagonally downward onto the fabric in a state in which the continuously supplied fabrics face each other in the middle; The fabric is characterized in that swinging members which are distributed and swing-driven by driving means are provided below the section on both sides of the fabric.

(Function) The fabric supplied to the fabric receiving recess is first sent to the swinging member in a state where both side surfaces of the fabric are sufficiently wetted with the processing liquid sprayed from the processing liquid spraying unit.

Next, the fabric sent to the swinging member is swung by the swinging member and is tightly folded and stored in the fabric receiving recess, but at this time both sides of the fabric are covered with the processing liquid. As the fabric is wetted, a liquid curtain is formed by the processing liquid that flows down along both sides of the fabric, and this liquid curtain acts as a lubricant between the fabric and the swinging member, so that the fabric does not stick to the swinging member. Without,
The continuously supplied fabric is smoothly and tightly folded and stored in the fabric receiving recess.

(Example) An example of the present invention will be described below based on the drawings.

FIG. 1 shows a schematic side view of a desizing device for continuously desizing a long fabric, and reference numeral 1 in the figure indicates the entire device.

This desizing device 1 includes a saturator section 4 that impregnates the fabric 2 with a decomposed size liquid 3 in advance, and a timing section 5 that adjusts the processing time of the fabric 2 to a predetermined time.

The saturator section 4 is configured with a bathtub 9 containing a size decomposition liquid 3 and a squeezing roller 10, and after immersing the continuously supplied long fabric 2 in the size decomposition liquid 3, Transfer glue decomposition liquid 3 to roller 1
The procedure for narrowing down with 0 is repeated twice.

The timing unit 5 includes a plurality of rollers 1 arranged vertically in the upper half of the interior of the casing 12.
3, 13... A heating space 14 is formed in which the fabric 2 is wound in a zigzag pattern and the temperature is raised during that time, and the fabric is placed in a bathtub 15 containing the glue decomposition liquid 3 in the lower half. An immersion device (retention device) 16 is formed to immerse the liquid.

The immersion device 16 is provided with an oval and loop-shaped inner conveyor 17 whose lower end portion is immersed in the glue decomposition liquid 3 in the bathtub 15, and which is provided to cover the majority of the outer circumference of the inner conveyor 17. A folding supply device 19 is provided above one side of the inner conveyor 17 (on the left side in the figure).

Further, on the surface of the inner conveyor 17, dividing walls 20, 20, .

The folding and supplying device 19 folds and supplies the long fabric 2 to the fabric receiving recess 20.
As shown in the figure, the processing liquid injection section 22 and the swinging member 23

5, and a pressure pump 25 for supplying the decomposed adhesive liquid 3.

The swinging member 23 has plate-like members arranged in a substantially "V" shape on both sides of the fabric 2, and an eccentric cam 2 that is rotationally driven by a rotational drive means (not shown) via an interlocking link 26.
7, it is configured to swing from side to side about a pivot shaft 28 provided at the top.

Furthermore, the partition walls 20, 20... and both conveyors 17, 18 are made of corrosion-resistant metal or resin material to have ventilation or water permeability. Both conveyors 17 and 18 are configured to rotate intermittently in the same direction.

In addition, the reference numeral 29 in the figure is a guide plate, and 30,
31 are excessive steady rest plates, respectively.

The operation of the folding and supplying device 19 of the desizing device 1 configured as described above will be explained next.

First, the fabric 2 supplied to the saturator section 4 is supplied to the timing section 5 in a state where it is sufficiently impregnated with the size decomposition liquid 3.

In the timing part 5, the temperature is raised while the rollers 13, 13... in the temperature increasing space 14 are wound in a zigzag manner, and then the paper is formed by the partition walls 20, 20, etc. via the folding supply device 19. The fabric is supplied to the fabric receiving recess 21, and is stored in the fabric receiving recess 21 by being tightly folded upward from the bottom.

At this time, the fabric 2 supplied to the fabric receiving recess 21
is a state in which both sides of the fabric 2 are sufficiently moistened with the size agent decomposition liquid 3 sprayed from the treatment liquid spraying section 22 flowing along both sides of the fabric 2, forming liquid curtains of the size agent decomposition liquid 3. and sent to the swinging member 23.

Next, the fabric 2 sent to the swinging member 23 is swung left and right here and is tightly folded and stored in the fabric receiving recess 21. The liquid curtain of the glue decomposition liquid 3 acts as a lubricant between the fabric 2 and the swinging member 23.

Therefore, the fabric 2 does not stick to the swinging member 23, and the fabric 2 that is continuously supplied is smoothly and tightly folded and stored in the fabric receiving recess 21.

In the above embodiment, an example was explained in which the folding and feeding device for the long fabric to the retention device was implemented in the desizing device, but it goes without saying that this can also be implemented in each device for scouring, bleaching, and washing. It is about.
