Description

[Detailed explanation of the invention] (a) Industrial application field This invention is applicable to linen fabrics, cellulose cotton fabrics,
This invention relates to an automatic cloth beating device that increases the flexibility and luster of staple fibers, general textiles, etc. by hitting them, thereby increasing the texture of the fibers.

(b) Conventional technology In the past, the above-mentioned cloth was rolled up several times to form a cloth bundle, and the surface of the cloth was constantly struck with a stick by a person to generate frictional heat between the fibers of the cloth, thereby changing the texture. I was trying to increase it.

(c) Problems that the invention attempts to solve However, when a person grasps both ends of a heavy bundle of cloth,
The work involves hammering the entire surface over a long period of time while rotating, which is not only very hard work, but it is also extremely difficult to hammer the entire surface evenly and evenly, resulting in inconsistent quality. . In some cases, this work could damage the fibers of the cloth, so it was a job that could only be done by highly skilled people.

This invention was made to eliminate the above-mentioned drawbacks, and it allows the rotation of the cloth bundle and the striking of its surface to be performed automatically at the appropriate timing, resulting in uniform quality with excellent texture. The purpose of this invention is to provide a device that can finish the fabric.

(d) Means to solve the problem To explain this invention based on the drawings, the first
As shown in FIGS. 1 and 2, a pair of rotating rollers 3 for placing a cloth bundle 2 and freely rotating it are disposed on a board 1 made of zelkova wood or the like, facing each other on both sides in the longitudinal direction. A rotary drive unit 5 is disposed in which holding parts 4 for holding both ends of the cloth bundle 2 are connected to each other. The gripping portion 4 is composed of, for example, a chuck mechanism with a double claw body, and is configured to be openable and closable. Further, the rotation drive section 5 is composed of a motor with a variable speed reducer, etc., and can be set to an appropriate rotation speed.

On the other hand, above the cloth bundle 2 placed on the rotating roller 3, there is a hanging member 20 in which a rope 8 is connected to a rod 7 in which a block-shaped mallet 6 made of zelkova wood or the like is connected. a winding drum 9 for winding up or unwinding the rope 8;
Place. The mallets 6 are arranged in a line along the entire longitudinal direction of the cloth bundle 2 at regular intervals. All the winding drums 9 are fixed to a rotating shaft 10, and one end of the rotating shaft 10 is detachably fixed to a suitable clutch 11 and a rotary drive unit 12 connected thereto, so that the clutch 11 can be attached and detached. It consists of a lifting and dropping device 13 that operates to raise or lower the mallet 6 alternately and at predetermined time intervals by winding up or unwinding the rope 8 by the rotation of the winding drum 9. There is. The above mallet 6
a winding drum 9, a rotating shaft 10, which operates the rising and falling of the
All the operating parts such as the clutch 11 and the rotary drive part 12 are arranged on the upper pedestal 14, and wheels 15 are attached to the lower part of this upper pedestal 14 at four places, and two rails 17 are arranged in parallel on the upper part of the lower pedestal 16. Pivotally supported above. Further, a back-and-forth movement drive unit 19 having a clamp scroll chuck 18 connected thereto is hooked to one end of the pedestal 14, and the entire upper pedestal 14 is moved around the rotating shaft 10.
It is configured to be able to move a predetermined distance back and forth in the axial direction (A-A in the figure).

In addition, the cloth bundle 2 is provided with linen fabric, cellulose-based cotton fiber, staple fiber, general fabric, etc.
In one row, the cloth bundle 2 has a diameter of about 150 mm and a length of about 1500 mm after being rolled up many times, and when carrying out the process, the cloth bundle is wrapped in a separate cloth bag and both ends are tied with a string. Further, the weight of the mallet 6 is preferably about 7 to 8 kg, and its rising and falling height is preferably about 40 to 50 cm.

(E) Function In this method of use, the cloth bundle 2, which has been properly moisturized beforehand, is placed on the rotating roller 3, and both ends of the cloth are held by the holding portions 4. When the rotation drive unit 5 is operated, the cloth bundle 2 rotates at a slow speed. On the other hand, when the rotation drive section 10 on the upper frame 14 is operated, the rotation shaft 10 rotates based on the engagement and disengagement operation of the clutch 11, and the winding drum 9 fixed thereto rotates. When the rope 8 is wound up, the mallet 6 suspended therefrom rises. When the clutch 11 is released, the rotary shaft 10 rotates freely, so the rope 8 is unwound, and the mallet 6 falls freely under its weight and hits the surface of the cloth bundle 2. Every time one cycle of raising and falling the mallet 6 is completed, the clamp scroll chuck 18 connected to the upper frame 14 is operated to move the mallet 6 back and forth, and then rise again at that position. , completes one cycle of falling. If this cycle continues for about 5 to 8 hours and the entire surface of the cloth bundle 2 is uniformly struck, frictional heat is generated between the fibers of the cloth, the temperature rises, and the humidity gradually decreases. Increases gloss. The fabric has increased flexibility and luster, resulting in a fabric with excellent texture.

(f) Embodiment FIGS. 3 and 4 are plan views showing another embodiment of the suspended mallet 6, in which two rotating shafts 10, 10' are arranged side by side on the upper frame 14. 9 rolls for each
and attach a mallet 6. The mallets 6 are suspended one by one in a line, and when the mallet 6 of one rotating shaft 10 is raised, the mallet 6 of the other rotating shaft 10' is suspended.
Configure it so that it falls.

Note that the present invention is not limited to the case where the mallets 6 are arranged in two rows in parallel as in the above embodiment, but can be implemented even if they are arranged in a plurality of rows.

Alternatively, a plurality of sets of the first and second embodiments may be arranged so that a plurality of bundles of cloth can be processed at one time.

(G) Effects of the invention According to this invention, all that is required is to place the bundle of cloth 2 on the rotating roller 3, and the mallet 6 automatically strikes the surface of the bundle 2, which eliminates the need for conventional methods. They are not forced to do hard labor. By setting the time intervals between the rise and fall of the mallet 6 and its back-and-forth swinging, as well as the rotational speed of the cloth bundle 2 at appropriate timings, it is possible to strike the fibers of the cloth under the most suitable conditions, so that the impact is uniform. It can be finished into cloth with excellent quality and texture, and can be easily processed even by non-experts.

Furthermore, as in the second embodiment, by dividing the suspended mallets 6 into two groups and making them alternately rise and fall, the impact of the cloth bundle 2 can be changed more precisely. This makes it possible to freely change the type of cloth fibers, their thickness, and the degree of finish, and apply processing that matches the cloth.
