Description

[Detailed description of the invention] [Field of industrial application] The present invention is applicable to, for example, rolls of elastic bandage knitted with a ratchet knitting machine, rolls of long narrow cloths such as tapes and ribbons, etc. The present invention relates to a multi-row winding device which arranges a large number of rolls in parallel and simultaneously draws them out in a parallel state to wind and form a fixed-length roll product having a predetermined length, constant winding diameter, and winding hardness.

[Prior art]

A thin cloth such as a houbi knitted using a Ratssel knitting machine is first wound around a thick core as a long length, and is then wound to a predetermined length, e.g. 4 m, 5 m, etc.
The cloth is cut into standard lengths such as 3.5 ft., 9 m, etc., then rolled up so that the hardness and diameter are constant and shipped as a roll product. Most of the work is done by hand, especially when winding stretchable cloth using spandex yarn or bulky elastic threads of synthetic fibers for the warp yarns. It was difficult to wind the material into a roll with a winding diameter and hardness of 1,000,000, and it was extremely inefficient.

Therefore, in order to improve the efficiency of the conventional thin cloth winding work, as shown in FIG. A winding roller 4 is rotatably supported at the tip of a swing arm 3 whose end part swings about a fulcrum 2, and is driven by a motor in parallel to the winding core 1. Rotation in a certain direction is applied to the winding core 1 by contacting the winding core 1 with the winding core 1, and the thin cloth S is wound around the outer periphery of the winding core 1 with a constant winding diameter and winding hardness, and the winding operation is performed. A winding device has been proposed for producing a coreless roll-like product, which is usually sold as a bandage, by pulling out the core 1 in the axial direction [Utility Model Publication No. 158/1983] reference〕.

In the conventional winding device as described above, when winding a thin cloth S which is supplied in a row in the longitudinal direction as shown in FIG. 6, the winding core 1
Since the length of each narrow cloth S is considerably long, the tension T applied to each narrow cloth S causes the core 1 to rotate while remaining bent, and the narrow cloth S is wound around the core 1 while changing the angle of intersection between the narrow cloth S and the core 1. As a result, the narrow cloth S becomes biased to one side as the winding diameter increases, making it impossible to properly wind it into a cylindrical shape, or the force clamping the tip of the narrow cloth S is insufficient, causing the narrow cloth S to come off the core 1. This phenomenon is particularly noticeable when the tension acting on the narrow cloth is large during the winding operation of the stretchable narrow cloth as described above.

Of course, it is also possible to increase the diameter of the core 1 itself to improve its rigidity and suppress deflection during winding, but in this case, the outer peripheral surface of the core 1 and the thin cloth S
Winding core 1 increases the contact area with the winding part of
It becomes difficult to pull out the core 1 from the roll product, and when the core 1 is removed from the roll product, cavities and wrinkles are formed in the center, which reduces the appearance and commercial value of the product. do not have.

[Problem that the invention attempts to solve]

The present invention aims to solve the problem of the product winding condition caused by the deflection of the core during winding, which is caused by the deflection of the core during winding, which was present in such conventional thin cloth winding devices, especially for winding devices such as stretchable thin cloth cloths whose cores are later removed. Focusing on the problem of deterioration, we used a core with a rectangular cross section that has a small effective contact area with the cloth and is easy to remove the core.
By rotatably supporting the middle part of the winding core through a disk-shaped support member, the winding core is prevented from bending in the direction in which the tension of the thin cloth is applied, and the winding core is always kept straight to improve efficiency. The purpose of this is to wind up thin cloth.

[Means for Solving the Problem] The configuration of the present invention to achieve the above object is to draw out a plurality of long narrow cloths, and have two rectangular ends extending in the width direction perpendicular to the drawing direction. In an apparatus for dividing and winding a plurality of fixed-length rolls by sandwiching the winding core between cross-sectional wires, a center hole through which the winding core is inserted, and a center hole extending from the center hole to the outer circumferential surface in a radial direction. At least one core having a slit for inserting and removing the winding core, and a winding core slip-off prevention member that is movable between a position where the slit is closed and the winding core is clamped and held in the center hole, and a position where the slit is opened. The disc-shaped support member is inserted into the core at an intermediate position of the core, and is fitted into a guide groove of a bearing member so as to be rotatably supported together with the core.

The core slip-off prevention member 31 is for preventing the core 11 inserted into the center hole 28 from moving toward the slit 29 as the disc-shaped support member 27 rotates. The slit 29 is rotatably supported around a shaft 32 provided near the center hole 28 between a closing position and an opening position, and when the slit 29 is closed, its outer periphery is is formed in an arcuate shape so as to be flush with the outer circumferential surface 27a of the disk-shaped support member 27.

The winding device of the present invention has the above-mentioned configuration, and its operation will be explained next. First, the original fabric is rewound onto the winding core 11, and the thin cloth S that is drawn out is rolled to a fixed length. When winding up the cloth, the ends of each thin cloth S are held between the facing surfaces of the metal wires 11a and 11b of the winding core 11 in advance, and both ends of the winding core 11 are held by the chuck members 14 and 14'. At the same time, the second
As shown by the two-dot chain line in FIG.
The intermediate portion of the winding core 11 is inserted into the center hole 28 of the disc-shaped support member 27 through the opening.

At this time, the winding core 11 is linearly supported by the chuck members 14, 14' and the disc-shaped support member 27 at both ends and a middle portion thereof.

In this state, the motor 21 is driven and the core drive shaft 1 is
5, 15' are rotated in the direction of arrow X, the winding core 11 connected to the drive shafts 15, 15' via the chucks 14, 14' rotates in the same direction, and the thin cloth S is attached to the outer periphery of the core 11. are divided and wound in parallel with the required winding hardness.

At this time, the disc-shaped support member 27 rotating together with the winding core 11 is moved in a direction in which the outer periphery of the core slip-off preventing member 31 contacts the guide groove 26 of the bearing member 25 and closes the slit 29 around the shaft 32. That is, it automatically rotates in the direction of arrow Y in FIG. 2 and comes into contact with the outer surface of the winding core 11 to prevent the winding core 11 from coming out of the center hole 28.

Further, when the disc-shaped support member 27 further rotates and the slit 29 faces toward the direction T in which the tensile force is applied to the thin cloth S, the core slip-off prevention member 3 is rotated as shown in FIG.
Since the outer periphery of the core 11 contacts the guide groove 26 and closes the slit 29, the winding core 11 comes into contact with the core slip-off preventing member 31 and is prevented from moving in the tensile force acting direction T, thereby preventing the entire deflection. is prevented.

Therefore, the winding core 11 rotates while always being supported straight by the chucks 14, 14' and the disc-shaped support member 27, and the thin cloth S is wound properly around its outer periphery in a roll shape. The winding drive stops when a fixed length has been wound.

The fixed-length roll material wound around the winding core 11 in this manner is then removed from the winding device together with the winding core 11.
is released, the core retaining member 31 of the disc-shaped support member 27 is raised as shown by the two-dot chain line in FIG. 29 through center hole 2
It can be easily removed from 8. The plurality of fixed-length roll products wound around the core 11 in this manner are separated into individual products by removing the core 11 in the axial direction.

In the above embodiment, the winding core bearing mechanism B consisting of the bearing member 25 and the disc-shaped support member 27 is
Although the case in which one is provided in the middle position of the winding core 11 is shown, when the winding core 11 is made even longer and a greater number of thin cloths S are wound in parallel, the winding core bearing mechanism B By arranging a plurality of them at approximately equal intervals along the axial direction of the winding core 11, it is possible to prevent the warping of the winding core 11 without increasing the thickness of the winding core 11, and to wind the thin cloth S into the correct cylindrical shape. I can do it.

[Effect of idea]

As described above, the winding device of the present invention pulls out a plurality of long narrow cloths, and places the tips between the winding cores made of two rectangular cross-sectional lines extending in the width direction perpendicular to the drawing direction. In an apparatus for dividing and winding a plurality of fixed-length rolls by sandwiching them, a disc-shaped support member is disposed at an intermediate position in the width direction of the winding core, and the winding is carried out through the disc-shaped support member. The middle part of the core is rotatably supported at at least one point, and the thin cloth is wound while keeping the core in a straight state at all times, so it cannot handle large tensions like an elastic band. It is possible to always wind the thin cloth into an accurate cylindrical shape perpendicular to the winding core without bending the winding core even when the winding core is bent, and it is also possible to reduce the cross-sectional area of the winding core. Therefore, it is possible to reduce the cavity that occurs when the core is removed from a roll-shaped product, prevent the occurrence of wrinkles, and increase the product value.In addition, the middle part of the divided core can be tied together with a disk-shaped support member. death,
Since it is possible to prevent the division opposing surfaces of the winding core from shifting, an excellent effect is exhibited in that the tip of the narrow cloth does not come off from the winding core immediately after the start of winding, and the cloth can be reliably wound.

Furthermore, according to the present invention, even when the winding core is extended and multiple rows of thin cloth are wound at once, it is possible to simply install multiple winding core bearing mechanisms at intervals along the axial direction of the winding core. , it is possible to prevent the core from bending without increasing the cross-sectional area of the core, and it is possible to correctly wind up the thin cloth, and together with the ease of the core removal work, the efficiency of the winding operation is greatly improved. It is also expected to have the effect of improving

The device of the present invention is extremely useful for forming bandages made of stretchable knitted fabric, but it is also useful for forming tapes,
It is also suitable for use in multi-row winding of thin cloths such as ribbons.
