2. Description of the Related Art Conventionally, the sheet material cutting by various means has been performed in the work such as affixing a sheet of building interior materials and packing various products. These sheet materials are manually cut. Along with cutting, various automated mechanical cutting devices have been developed. Examples of these automated or semi-automated sheet material cutting devices include, for example, JP-A-63-139690, JP-A-63-144994, JP-B-141586, JP-A-2-30489, and JP-A-3-7492. There are known ones having various configurations and mechanisms disclosed in the above publication.

However, these conventional sheet material cutting devices are limited to those for cutting the long sheet material in either the length direction or the width direction thereof. For this reason, in the case of the conventional cutting device, this is used only to create another new original fabric from the original fabric, to create a standard length sheet material, to create a sheet roll with a predetermined width direction, etc. I was just doing it.

However, in the case of using a sheet material as a building interior material, or using a foamed sheet material for cushions, packaging, etc., it is possible to freely set a predetermined length and width in various dimensions. A means capable of cutting is required. In fact, when the sheet material is used for cushions, packaging, etc., its purpose of use is wide, and the size and shape of the target product are various. For this reason, there is an increasing demand for sheet materials having various vertical and horizontal dimensions as secondary processing from sheet materials.

Under these circumstances, there is a need for means capable of freely setting the predetermined size and the required number of sheets and easily producing sheet material pieces. However, depending on the conventional apparatus as described above, It was difficult to meet such a request. The present invention has been made in view of the above circumstances, eliminates the drawbacks of the conventional cutting device, can be freely cut in the length direction and the width direction, and is easy to handle and maintain. Moreover, it is an object of the present invention to provide a new sheet material cutting device which is easily portable.

In order to solve the above-mentioned problems, the present invention has a feed roller mechanism for feeding a sheet material and a measuring roller, and lengthens the sheet material after setting a predetermined dimension by the measuring roller. A length cutting blade that can be moved orthogonally to the sheet material to be cut in the vertical direction and a width cutting blade that is positionally fixed to the stay in the width direction of the sheet material. And a sheet material cutting device that can be cut in the width direction.

Further, according to one aspect of the present invention, the feed rollers are arranged in front of and behind the lengthwise cutting blade, and the widthwise cutting blade is arranged in front of the lengthwise cutting blade. As well. Hereinafter, the sheet material cutting device of the present invention will be described in more detail with reference to the drawings.

1 and 2 of the accompanying drawings are a front view and a side view showing an embodiment of a sheet material cutting apparatus of the present invention. For example, as shown in FIGS. 1 and 2, the sheet material cutting device of the present invention has
It has a sheet material cutting section (1), a raw sheet supply section (2), and an operation section (3).

The sheet material cutting section (1) has, for example, an openable upper cover (4) and a lower cover body (5),
The operation part (3) is installed on the upper cover (4), and
A delivery roller and a cutting blade are provided between the upper cover (4) and the lower cover body (5). Operation part (3)
Makes it possible to operate the device either daily or half-day.

FIG. 3 exemplifies a state in which the upper cover (4) is opened. As is clear from FIG. 3, the sheet material cutting device is in contact with the surface of the sheet material (7) fed from the original fabric roller (6), and the upper and lower feeding rollers (8) for pulling and feeding the sheet material (7) together with the sheet material It has a measuring roller (9) for measuring the length of (7) to a predetermined dimension, and after the dimension is set by this measuring roller (9), the sheet material (7) is cut to a predetermined length. Cutting blade (10)
I am wearing.

In this example, a pair of vertical feed rollers (8), a feed roller (8) and a measuring roller (9) are combined. The lengthwise cutting blade (10) is arranged at an intermediate position of this combination, that is, between the two feeding rollers (8) of the lower cover body (5), and is arranged in the lengthwise direction of the sheet material (7). The sheet material (7) is allowed to move in the orthogonal direction, and the sheet material (7) is cut in the lengthwise direction to a predetermined dimension by the left and right movements.

Also, in this example, the stay (1) provided with a length measuring tool in the width direction of the sheet material on the upper cover (4).
1) is arranged, and the widthwise cutting blade (12) is attached and fixed to this so that the position can be adjusted. Longitudinal cutting blade (1
FIG. 4 is an enlarged view of the vicinity of 0). In the slit (13) formed by the guide table between the two feeding rollers (8) attached to the lower cover body (5), this lengthwise cutting blade (10) is in the sheet feeding direction (A). The sheet material is moved right and left so as to be orthogonal to each other, and the sheet material is cut into a predetermined lengthwise dimension. The movement of the lengthwise cutting blade (10) is caused by the toothed pulley (14) as illustrated in FIG. 5, for example.
The toothed belt (15) is mounted on the toothed pulley (15), and the toothed pulley (14) is driven and rotated. Along with this, the lengthwise cutting blade (10) is moved left and right, thereby cutting the sheet material. Therefore, two cutting edges (10a) are provided outward.

The delivery roller (8) and the toothed pulley (14) are activated by the transmission of power from a suitable drive. In addition, width direction cutting blade (1
Regarding 2), the installation position can be automatically adjusted by a feed screw mechanism or the like. Further, FIG. 6 is a sectional view showing another example of the present invention. In this example as well, the basic configuration of the sheet material cutting device has not changed.

A widthwise cutting blade (1) for cutting the sheet material (7) supplied from the original fabric roller (6) into a predetermined width dimension.
The sheet material (7) cut by 2) and then sent out by the sending roller (8) is cut by the lengthwise cutting blade (10) into a predetermined length as described above. At this time, the length of the sheet material (7) is measured by the measuring roller (9).

The delivery roller (8) can further drive the lengthwise cutting blade (10) by an appropriate drive source (16) or the like. Also in this example, the sheet material (7)
Is supported and pulled by the feed roller (8), so that it does not sag when cut by the lengthwise cutting blade (10). Therefore, sharp and accurate cutting is possible.

Further, as shown in FIG. 6, the sheet material (7) supplied from the original fabric roller (6) is tensioned by a tension stay (17), so that the sheet material (7) is fed. Even at the time of cutting with the widthwise cutting blade (12), the sheet material (7) does not sag, and sharp and accurate cutting is possible. Since the cut sheet material (7 ') is usually charged with static electricity, in order to prevent it, the pedestal (18) is easily slipped off by making a step with a threshold slip or the like. Structure is also effective.

In any of the above structures, the measuring roller (9) can be rotated by friction with the sheet material (7) in a free state, and the length can be measured from this rotation by the rotary encoder. With these configurations, it is possible to easily cut the sheet material in a predetermined dimension in the length direction and the width direction. In addition, the above simple configuration is
The operation and maintenance are facilitated, and the transportation to the work site is facilitated.

Of course, the present invention is not limited to the above examples. There are various possible details of the structure.
