Abstract

A sheet cutting machine capable of cutting a sheet into a desired length is provided. A sheet cutting machine includes a cylindrical rotating tool 2 fitted into a cylindrical sheet 1, holding tools 3a and 3b that rotatably hold the rotating tool 2, and a space between a support column 6a and a support column 6b. The cutter guide 5 is connected in parallel with the short side of the sheet 1. The sheet cutting machine column 6b is provided with a scale notation 4 in which a scale is provided with the position of the cutter guide as the origin along the direction of drawing the sheet. By cutting the sheet along the cutter guide 5 with a cutter knife or the like, the sheet can be cut to a desired length. [Selection] Figure 2

Description

The present invention is a sheet cutting machine capable of accurately and easily cutting a sheet to a desired length without requiring a special device or a wide installation place.

2. Description of the Related Art Conventionally, as a sheet-like cutting machine, for example, a film cutting machine (Patent Document 1) that can draw a roll-like film and cut it at the drawn-out place is known.

Japanese Utility Model Publication No. 3-87594

However, according to the above-described method, since the length when cutting a sheet (film) is determined by measurement, inconveniences such as erroneously cutting long or short are often caused. Also, since the device itself is complicated and requires a large installation place, it is difficult to install it simply.

The present invention has been made in view of the above circumstances. A sheet is fixed to the upper part of two sheet cutting machine columns, and a scale is provided on the column with the position of the cutter guide as the origin along the direction in which the sheet is pulled out. Thus, the sheet cutting machine is capable of accurately and easily cutting a sheet wound in a roll shape into a desired length.

By using the above-mentioned means, a sheet cutting machine capable of accurately and easily cutting a sheet wound in a roll shape to a desired length at low cost without requiring a special device or a wide installation place. provide.

A cylindrical rotator 2 that enables rotation while holding the sheet 1 wound in a roll shape, and holders 3a and 3b that are provided on the column 6a and the column 6b and hold the column rotator 2 rotatably, and a column 6a. The sheet cutting is composed of a cutter guide 5 provided in parallel with the short side of the sheet 1 between the column 6 and the column 6b, and a scale notation 4 attached on the column with the position of the cutter guide 5 as the origin along the sheet drawing direction. Machine.

Usually, the sheet 1 is wound around a cylindrical roll core made of cardboard or the like, and the cylindrical rotating tool 2 is usually a cylindrical shape inserted into the roll core, and the outer diameter thereof is the inner diameter of the roll core. The length is longer than that of the sheet 1 and can be attached to both sides of the holders 3a and 3b.

The holders 3a and 3b are adjusted to the size of the cylindrical rotating tool 2, and the pillars 6a and 6b are mounted with L-shaped ones so that the cylindrical rotating tool 2 and the sheet 1 do not fall when the sheet 1 is pulled out. The projection is provided upward.

The cutter guide 5 is composed of two bars that connect the column 6 a and the column 6 b and are provided on the lower side of the sheet 1 in parallel with the short side of the sheet 1. This bar is preferably made of steel. The distance between the two bars is such that the cutting edge of a cutter such as a cutter knife passes through. The sheet 1 is cut by moving the cutter such as a cutter knife left and right along the cutter guide 5.

The scale notation 4 is provided along the support 6a and / or the support 6b, and indicates the length downward along the support with the cutter guide 5 as the origin.

As described above in detail, according to the sheet cutting machine of the present invention, a sheet wound in a roll shape can be accurately and easily cut to a desired length without requiring a special device or a wide installation place at a low cost. be able to.

It is an enlarged view of the sheet | seat part and cylindrical rotating tool part of the sheet cutting machine of this invention. It is a front view of one specific Example of the sheet cutting machine of this invention. It is a left view of one specific Example of the sheet cutting machine of this invention.

An embodiment will be described below with reference to the accompanying drawings. The sheet cutting machine according to the present invention inserts a cylindrical rotating tool 2 into the core of a sheet 1 wound in a roll shape, as shown in FIG. This is fitted into supporters 3a and 3b provided on the support column 6a and support column 6b that rotatably hold the columnar rotary tool 2 as shown in FIG. And there is a cutter guide 5 provided between the column 6a and the column 6b in parallel with the short side of the sheet 1, and a scale notation 4 is set with the position of the cutter guide as the origin along the direction of drawing the sheet to the column 6a. Prepare. The sheet 1 is pulled down to a desired length along the scale notation 4 of the column 6a, and when the desired length is reached, the sheet is cut with a cutter knife along the cutter guide 5 to the desired length. Can be cut.
