Abstract

(57) [Problem] To provide a processing apparatus in which a striking rod after striking a cloth is hard to rub the cloth. SOLUTION: This device hits a cloth A carried on a transporting rotation roll 6 by a tip end portion of a striking elastic rod 9. The rod 9 is attached to a rotary roll 11 for hitting the cloth, and hits the cloth A by the rotation of the roll 11. The rod 9 is formed in an arc shape, and the arc is the roll 1
1 bulges in the direction of rotation. Therefore, when the bulging portion of the arc (the middle portion of the rod 9) hits by the stopper member 10 provided between the roll 6 and the roll 11, the tip of the rod 9 is rotated by the inertia of rotation and the elasticity of itself. The cloth A on the roll 6 is hit by whipping in the rotation direction. Thereafter, the tip of the bar 9 is separated from the fabric by the repulsive force of the impact, the elasticity of the bar 9 itself, and the rotation of the roll 11. [Effects] Immediately after the impact, the tip of the rod 9 is separated from the cloth, so that the cloth is hardly rubbed and the cloth is hardly damaged.

The present invention relates to a fabric processing apparatus used in such a case.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a cloth is subjected to a softening treatment, a relaxation treatment, a untwisting treatment, or a graining treatment by giving an impact to the cloth. As an apparatus for applying an impact to the cloth, for example, an apparatus for blowing a high-pressure water stream onto the cloth or an apparatus for hitting the cloth with a hitting rod (Japanese Utility Model Registration No. 2544458) is known.

The apparatus described in Japanese Utility Model Registration No. 2544458 discloses a rotary shaft 14, a striking flexible filament 15 attached to the rotating shaft 14, and a striking flexible filament 15. This is an apparatus for hitting a cloth A carried on a conveyor belt 18 by a rotary impact means 13 composed of a hitting ball 16 attached to the tip of the cloth. Before the hitting ball 16 hits the cloth A, the flexible wire 16 for hitting is bent by the stopper member 17 in a direction opposite to the rotation direction, so that the impact of the hitting ball 16 on the cloth A is increased. The cloth A can be effectively hit. However, when the cloth A is hit with this apparatus, the striking ball 16 colliding with the cloth A rubs the cloth A in the rotation direction (transport direction). Therefore, there was a drawback that the cloth A was damaged by the friction of the hitting balls 16.

[Problems to be solved by the invention]

 The present invention is an apparatus similar to the apparatus described in Japanese Utility Model Registration No. 2544458, in which a cloth is hit with a rotating hitting rod. It is an object to provide a device.

[0005]

[Means for Solving the Problems]

 That is, the present invention provides a transporting rotary roll for transporting and carrying a fabric, a rotary roll for punching having an impact striking rod attached thereto, and a rotary roll between the transporting rotary roll and the rotary roll for punching. Provided with a stopper member provided, wherein the interval between the rotating roller for conveyance and the rotating roller for striking is such that the distal end of the striking elastic rod can strike the cloth carried on the rotating roller for conveyance. The stopper member is disposed at a position where the middle portion of the striking elastic bar hits when the tip of the striking elastic bar strikes the fabric. The present invention relates to a cloth processing apparatus characterized in that it has an arcuate shape which swells in the rotation direction of the rotary roll for punching.

[0006]

[Action]

 The operation of the device according to the present invention for striking the cloth is as follows. The elastic rod for striking rotates with the rotation of the rotating roll for striking. Since the striking elastic rod has an arc shape that swells in the rotation direction of the striking rotary roll, an intermediate portion (bulge portion of the arc) is formed between the striking rotary roll and the transport rotating roll. It hits a stopper member provided at a predetermined position. When the rotation of the striking elastic rod is stopped by the stopper member, the tip of the striking elastic rod whips in the rotational direction due to the inertia due to the rotation and the elasticity of the rod itself, and is carried by the transporting rotating roll. Hitting the fabric. After striking the fabric, the tip of the striking elastic bar separates from the fabric due to the repulsive force of the striking, the elasticity of the bar itself, and the rotation of the spinning roll. Therefore, the tip portion of the striking elastic bar immediately separates from the fabric after striking the fabric, so that rubbing of the fabric is reduced.

[0007]

[Embodiment of the invention]

 The device according to the present invention will be described with reference to the drawings. FIG. 2 is a schematic side view showing a state where the cloth is being processed by the apparatus according to an example of the present invention. Reference numeral 6 denotes a transport roll for transporting the cloth A. Further, the cloth A is hit by the tip of the striking elastic bar 9 on the transporting rotation roll 6, so that the cloth A is also for supporting the cloth A. The diameter of the transport rotary roll 6 is preferably 100 to 300 mm.

It is preferable that a cushion material 7 is wound around the surface of the transport rotary roll 6. If the cushion material 7 does not exist, the struck fabric A easily moves to the left and right on the surface of the transporting rotation roll 6, and the yarn in the fabric such as a knitted fabric is deviated or the strength is reduced due to abrasion. There is fear. On the other hand, when the cushion material 7 is present, the struck fabric A moves in the thickness direction of the cushion material 7, so that the fabric A is less likely to move left and right on the surface of the transporting roll 6, and the knitted fabric or the like is used. The yarns in the fabric are less likely to shift or wear. As the cushion material 6, a felt, a non-woven cloth, a foam made of synthetic resin, or the like can be used, and the thickness thereof is arbitrary, but a material having a thickness of about 10 mm is actually used.

Reference numeral 11 denotes a rotary roll for striking, on which a striking elastic bar 9 is attached. For this attachment, the rear end of the striking elastic bar 9 (the end opposite to the leading end of striking the cloth A) may be fixed to the surface of the rotating roll 11 for striking by various means. For example, the rear end portion of about 30 mm of the striking elastic bar 9 may be bonded to the surface of the rotary roll 11 for striking with an adhesive. Further, the diameter of the rotary roll 11 for punching is preferably about 75 to 300 mm, and in practice, a diameter of about 120 mm is used.

The striking elastic rod 9 is flexible enough to pass through between the stopper member 10 and the rotary roll 11 for striking, and the stopper member 10 hits an intermediate portion of the striking elastic rod 9. At this time, any material may be used as long as the tip has a flexibility such that the fabric A carried on the surface of the transporting rotary roll 6 can be hit. Specifically, a rod made of rubber, for example, an acrylic rubber rod is used. The size and shape of the impacting elastic bar 9 are also arbitrary, but it is preferable to use, for example, a semi-cylindrical bar having a diameter of about 10 to 15 mm. Then, it is preferable that the cloth A is hit on the flat portion of the semi-cylindrical bar. Specifically, it is preferable to use an acrylic rubber semi-cylindrical rod having a diameter of about 12 mm, and to hit the cloth A with a flat portion at the distal end thereof. Further, it is preferable that the tip of the elastic rod 9 for hitting the cloth A is provided with irregularities, and the cloth A is hit with the projections. The reason is that the provision of the convex portion allows the impact force to be concentrated on the convex portion and gives a greater impact to the cloth A. The area where the unevenness is provided may be about 50 mm from the tip of the impacting elastic bar 9. The unevenness may be provided in any pattern. For example, it is preferable that the unevenness is a checkerboard-shaped unevenness. The shape of the striking elastic rod 9 is not limited to a semi-cylindrical shape, but may be a polygonal prismatic rod such as a triangle or a quadrangle. Also in this case, it is preferable that the cloth A is hit on the flat portion.

The striking elastic bar 9 is formed in an arc shape. The swelling of the circular arc is attached to the rotating roll 11 for setting so that the bulge is located in the rotation direction of the rotating roll 11 for forming. The degree of bulge of the arc is preferably such that the radius of curvature is about 50 to 60 mm. It is preferable that a plurality of striking elastic rods 9 are arranged in a line in the axial direction of the striking rotary roll 11 so that the striking elastic rods 9 can be struck over the entire width of the fabric A. Further, the striking elastic rods 9 may not be arranged in a line, but may be arranged in a staggered manner in the axial direction of the rotating roll 11 for striking. In the row of the striking elastic rods 9 attached to the rotary roll 11 for striking, a certain distance is provided between the striking elastic rods 9 adjacent to each other. Therefore, since the portion of the cloth A passing through the position corresponding to this interval may not be hit, it is preferable that the striking elastic rods 9 in the other rows are attached at positions that fill this interval. . That is, it is preferable that the mounting position in the axial direction of the striking elastic bar 9 in each row be different for each row. Further, it is preferable that the striking elastic rods 9 are attached in four to eight rows (four rows in FIG. 3) in the circumferential direction of the rotary roller 11 for striking. The length of the striking elastic bar 9 is preferably about 300 to 600 mm.

The rotating roll 11 for striking and the rotating roll 6 for conveyance are arranged at such an interval that the tip of the elastic rod 9 for striking the cloth A carried on the surface of the rotating roll 6 for conveying can be struck. Is placed. The rotary roll 11 for punching and the rotary roll 6 for conveyance may be rotated in opposite directions as shown in the drawing, or may be rotated in the same direction. In addition, the rotation speed of the two rotation rolls 11 and 6 may be arbitrarily set according to the type of the fabric A and the degree of the softening or relaxing treatment. When a larger softening treatment or a relaxation treatment is desired, the rotation speed of the rotary roll 11 for punching may be increased with respect to the rotation speed of the rotary roll 6 for conveyance. In practice, the rotation speed of the rotary roll for setting is appropriately set in the range of 200 to 400 rpm.

A stopper member 10 is provided between the rotary roll 11 for striking and the rotary roll 6 for conveyance. The position where the stopper member 10 is arranged is a position where the middle portion of the striking elastic bar 9 hits the stopper member 10 when the tip of the striking elastic bar 9 strikes the fabric A.

FIG. 3 is a schematic side view when the cloth is actually processed using the cloth processing apparatus according to an example of the present invention. The rotating roll 6 for conveyance and the rotating roll 11 for punching are arranged in three sets in the machine direction. The cloth A is introduced into the hot water or water 12 filled in the tank 1 by the pinch roll 4, and then introduced onto the surface of the transport rotary roll 6, where it is attached to the rotary roll 11 for punching. It is hit by the elastic bar 9 for use. After that, the fabric A is again introduced into the hot water or the water 12, and then subjected to the same impact treatment twice, so that the fabric A is subjected to the softening treatment or the relaxation treatment. The reason why the cloth A is introduced into the hot water or the water 12 is to alleviate the distortion (unevenness of the tension applied to the cloth A) of the cloth A, or to swell the strong twisted yarn to promote untwisting or graining. It is to do. Note that such an apparatus is generally covered with a cover 3.

[0015]

[Effect of the invention]

 In the apparatus according to the present invention, the striking elastic rod attached to the rotary roll for striking has a circular arc shape bulging in the rotation direction of the rotary roll for striking, and an intermediate portion thereof (bulge portion of the arc) is formed. When hitting the stopper member, the tip of the striking elastic rod is made to whip in the rotational direction by the inertia due to the rotation and the elasticity of the rod itself, and strikes the cloth carried on the transporting rotary roll. After striking the fabric, the tip of the striking elastic bar separates from the fabric due to the repulsive force of the striking, the elasticity of the bar itself, and the rotation of the rotating roll for striking. Therefore, the tip portion of the striking elastic bar immediately separates from the fabric after striking the fabric, and thus can prevent the rubbing of the fabric.

Therefore, if the fabric processing apparatus according to the present invention is used for softening, relaxing, untwisting or embossing the fabric, it is possible to prevent the fabric from being damaged. Thus, the desired processing can be performed.
