[Detailed description of the device]

[0001]

This invention relates to a double curtain scale device. More specifically, the present invention relates to a new double curtain scale device which does not impose a burden on the curtain material and can be automatically scaled to a desired height with a small dimensional error and cut.

[0002]

2. Description of the Related Art Conventionally, various measures have been taken to cut and sew a long cloth such as a curtain cloth by scaling it to a predetermined length or height. For example, in the case of curtains, the curtains are laid out on the hanger rails and hung, and the height is determined by the vertical scale that has been installed vertically. It is known to cut in a certain direction (Shokai 57-34887, etc.).

Further, conventionally, after the height is cut at a predetermined position in this manner, it is detached and sutured with an overlock sewing machine so that the centering portion is turned upside down. In order to improve the above, the applicant has proposed a device that can sew a curtain material that has been scaled and cut immediately in a suspended state (Japanese Patent Application No. 2-232264).

Although various improvements have been made to these various types of curtain fabric scaling and processing equipment, at present, there is still room for improvement in the automatic scaling and cutting of suspended curtain fabrics. However, the automation efficiency of scaling and cutting is not always satisfactory. This is because the curtain fabric is a knitted product of warp yarns and weft yarns, and therefore it is affected by bending and stretching of the fabric. This effect is significant for longer curtains.

In particular, since the warp threads are divided into blocks in one piece of cloth when the curtain cloth is formed, the warp tension may change for each block. For this reason, even if it is cut to a specified size on the table and actually hung, the lower end portion becomes wavy. In order to prevent this, it is important to cut the length while hanging it under its own weight.

However, in the case of a long curtain cloth, it is not so easy to maintain and improve the dimensional accuracy in consideration of its own weight. For example, as shown in FIG. 1, a method in which the tip on one side is fixed by a clamp (a) and the other end is cut by a cutter (c) as shown in FIG. Although it is possible to target relatively long fabrics in this case,
Even though the cutter (c) side is hung by its own weight, the cloth on the clamp (a) side is in a state in which the reverse tension is applied. For this reason, there is a limit to the improvement of the dimensional accuracy over the entire length of the cloth.

Further, as shown in FIG. 2, there is also known a folding-back system in which the middle of the curtain material in the lengthwise direction is folded back by a bar (k) and hung on a lifting bar (ki). In this case as well, since it is not a complete suspension method using its own weight, there is a drawback in that it is likely to be affected by a dimensional error after cutting. Therefore, the present invention solves the above-mentioned drawbacks of the conventional curtain scale device, and enables high-precision and highly-efficient scaling and cutting even with a long curtain material with a small dimensional error. The purpose of the present invention is to provide a new automatic curtain scale device.

[0008]

The present invention has been made in view of the circumstances as described above, and in order to solve the above-mentioned problems, a state in which a curtain cloth is widened in the width direction at its front end portion. The upper and lower curtain hanging hanger means that can be lifted up and down, and the lifting control means that is equipped with a counting device that automatically counts the height when the curtain hanging upper hanger means moves up and down, and the middle part of the suspended curtain material is nipped. A lower hanger means for freely moving up and down, and a lifting control means provided with a counting device attached to the lower hanger means for automatically counting the height,
Further, there is provided a double curtain scale device comprising a cutter means for cutting the lower end portion in a width direction at a desired height.

[0009]

In the double curtain scale device of the present invention, since the curtain material is suspended in two steps, it is easy to cut a long curtain which is higher than the ceiling height, and the curtain tip is Since the curtain is clamped by the upper hanger means for sandwiching and the lower hanger means for sandwiching the intermediate portion, the burden on the curtain fabric is less than that of the conventional roller elevating method and folding method, and the dimensional error can be kept small. it can.

Further, in the apparatus of the present invention, automatic switching type length measurement can be easily performed by an automatic counting device such as a rotary encoder attached to each elevating means of the upper and lower hanger means.

As illustrated in FIGS. 3 and 4, the device of the present invention is provided with a clamp means (2) for holding the curtain hanger in a state in which the curtain material is widened in front of an upper hanger means (1) which is long in the width direction and can be moved up and down. The upper hanger means (1) is provided with a driving means for raising and lowering the upper hanger means (1) and a raising and lowering control means provided with a counting device for automatically counting the height during raising and lowering. Also, this device is a lifting control means provided with a lower hanger means (3) which holds a middle portion of the curtain material and which can be raised and lowered, and a counting device attached to the lower hanger means, which automatically counts the height.
Further, a horizontal traveling cutter means (4) for cutting the lower end portion of the suspended curtain material in a width direction at a desired height, and a sensor for detecting the curtain material mounted on the cutter means (4) or in the vicinity thereof. And means.

The upper hanger means (1) and the lower hanger means (3) are supported by left and right columns (5) so as to be able to move up and down, and the up and down movement transmits the power of a motor as a drive means (6) by a chain or the like. By doing. The clamp means (2) for suspending the caten land on the upper hanger means (1) may have an appropriate structure as illustrated in FIG. 5, for example, the support plate portion (7).
The upper end of the curtain material (8) can be placed on, and the curtain material (8) can be set by pressing the curtain material (8) with the pressing portion (10) by operating the lever (9).

Next, the clamp means (2) is rotated in the direction (A) in the figure to bring the support plate portion (7) into a suspended state, and the curtain suspension upper hanger means (1) is moved upward by a predetermined height. The height of the curtain material (8) is adjusted to a predetermined height by raising the curtain material (8) to the height position and appropriately lowering it. The holding portion (10) and the support plate portion (7) are in a state of being inclined by about 90 ° while holding the curtain material (8) therebetween.

The clamping means (2) returns to the horizontal state shown in FIG. 5 and the lever (9) is manually or automatically operated after the operation and after the predetermined scaling and cutting are completed. Operate so that the curtains (8) can be opened all at once. For example, in order to adjust the height of the curtain material sandwiched by such clamp means (2) by elevating and lowering the upper hanger means (1) for hanging the curtain, an elevating control means provided with a counting device, for example, a rotary device is used. The computer can be automatically controlled using a counter such as an encoder.
