Abstract

PURPOSE:To provide the cutting device by disposing upper and lower cutters, etc., so as to insert the working portions of a comb tooth member between the warp portion of a long towel fabric, stop the working portions at the weft portion of the fabric and subsequently cut the fabric at the center portion of the warp portion. CONSTITUTION:In a cutting device of towel fabric, a driving motor 27 is rotated to rotate the working portions 24a of a comb member through a comb tooth section-attaching shaft 25, thereby inserting the working portions between the warps of a warp portion A1 of long towel fabric and catching a weft A2 dividing the warp portion to correct the curvature of the warp portion, followed by operating air-pressure cylinder devices 32 and 45 to fix the fabric with a press member 33 and a press plate 34. An air-pressure cylinder device 42 is operated to slightly move the comb tooth member 24 in the horizontal and forward direction to release the catching of the weft A2 with the working portions 24a and a motor 27 is rotated to separate the working portions 24a from the warp portion A1, followed by cutting the warp portion A1 at the center thereof with upper and lower cutters 28 and 29 disposed in the towel cutting device 6.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for cutting towel fabric into one towel material by straightening the bends from a long towel fabric in which warp portions are formed at regular intervals. The present invention relates to a cutting device.

[Conventional technology]

As a conventional cutting device of this kind, a large number of comb-tooth members perpendicular to a long towel fabric are fixed to a workbench or the like, and a section where only the warp threads of the towel fabric do not have weft (hereinafter referred to as
There is a method in which a series of comb teeth (referred to as a warp thread portion) are engaged with a series of comb tooth members, and the central portion of the warp thread portion is cut using an elevating cutter provided close to the comb tooth member.

[Problem to be solved by the invention]

However, in such a conventional towel fabric cutting device, when cutting the center portion of the warp portion before sewing the towel fabric, the lifting cutter is cut in a manner that prevents it from interfering with a fixed series of comb tooth members. It is necessary to provide the lifting cutter at a constant distance from the comb tooth member, which makes it difficult to shorten unnecessary warp portions of the towel fabric.

[Means to solve the problem]

This invention was made in view of such conventional technical problems, and its structure is such that one towel material is pulled out from a long towel material on which warp portions are formed at regular intervals. In a towel fabric cutting device that cuts warp threads, an action part protruding from the tip of the base end has several combs on the heel that can enter between the warp threads of the warp thread part and lock onto the weft threads that divide the warp thread parts. A tooth member, a comb tooth member attachment shaft that is arranged across the longitudinal direction of the towel fabric and fixes each base end of the comb tooth member at a predetermined interval, and a comb tooth member mounting shaft that inserts the action portion between the warp threads of the warp portion. Rotate the comb tooth member mounting shaft in one direction so as to remove the comb tooth member, and rotate the comb tooth member mounting shaft in the other direction to remove the comb tooth member, and remove the working portion of the comb tooth member. The towel fabric cutting device has a towel fabric alignment section that includes a moving mechanism that moves the comb tooth member attachment shaft in a direction to release the action section from the weft thread.

In addition, the action portion of each comb-tooth member enters the warp portion of the towel fabric and engages with the weft threads that divide the warp portion, and at the aligned position of the towel fabric, the center of the warp portion of the towel fabric is An upper cutter that descends from above the towel fabric and a lower cutter that rises from below can be provided so as to form a section.

[Effect]

To pull out one towel material from a long towel material with warp portions formed at regular intervals, first, the comb tooth member is integrated and the comb tooth member mounting shaft is rotated in one direction, and the action part is rotated. Press onto towel fabric. When the towel fabric is pulled out in each section in the width direction from this state, the action portions of the respective comb teeth members sequentially enter between the warp threads of the warp thread portion and engage the weft threads that separate the warp thread portions. As a result, the warp portions of the towel material are aligned and the bends are corrected.

After that, when the action parts of the comb tooth members are removed from the warp threads of the towel fabric, if the comb tooth member mounting shaft is slightly moved in the direction of disengaging the action parts from the weft threads, each action part can be removed. The lock with the weft is released.

Next, the comb tooth member mounting shaft is rotated in the other direction to release the operating portion of each comb tooth member from entering the towel fabric,
The comb tooth member is set at a position that does not interfere with the cutting of the warp portion, and the towel fabric is cut at the warp portion. As a result, one towel material is obtained.

In addition, an upper cutter that descends from above the towel fabric is placed in the center of the warp portion of the towel fabric that has been pulled out and aligned.
By providing a lower cutter that rises from below, the comb tooth member does not interfere when cutting the towel fabric, and it is possible to cut approximately the center of the short warp portion.

〔Effect of the invention〕

As understood from the above description, the towel fabric cutting device according to the present invention provides the following effects.

■When cutting a single towel material from a long towel fabric with warp threads formed at regular intervals, a comb tooth member is used to align the warp threads in the towel fabric alignment section and correct the bending of the towel fabric. After the warp portions are aligned, they are avoided from the warp portions, so even if the warp portions are short, the warp portions can be easily cut without being hindered by the comb tooth member. As a result, the warp portion of the towel fabric can be shortened and materials can be saved.

In addition, when the comb tooth member moves to the lowered position, the comb tooth member attachment shaft moves slightly away from the weft threads that separate the warp portions to avoid interference with the weft threads of the towel fabric.
The aligned weft yarn portions are prevented from being disturbed by the rotating comb tooth member, and the finished quality of the towel material is improved.

In addition, by providing the upper and lower cutters at the center of the warp thread portion when the towel fabric is aligned, the warp thread portion can be cut approximately at the center.
