Abstract

PURPOSE:To improve cutting accuracy and working efficiency by making the horizontal angle between a pair of upper and lower rotary knives variable, and cutting a sash by both the rotary knives raising the sash after positioning the sash moveably with respect to the longitudinal and crosswise directions. CONSTITUTION:A first rotary knife 1 rotating centering around a horizontal shaft 3 and a second rotary knife 2 rotating center-ing around a horizontal shaft 4 are arranged with a vertical gap, and a supporting stand 9 of the rotary knife 2 is able to turn centering around a rotary shaft 10 which is alligned with the edge of the rotary knife 1. Consequently, the horizontal angle between the upper and lower rotary knives 1, 2 is variable. The cutting position measured from the end face of a sash in the longitudinal direction is positioned, and then the sash is placed on a clamping frame 13 and fixed by clamps 14, 15. Then, a sliding plated 19 is traversed by a handle 22 and the cutting position from the side face of the sash is positioned. The rotary knife 2 is thus turned to have a specified horizontal angle to the rotary knife 1, the clamping frame 13 is raised, and the sash is cut by the upper and lower knives 1, 2 in sequence.

Description

[Detailed description of the invention] (Industrial application field) This invention relates to a sash processing device.

[Conventional technology]

Conventionally, for example, the long satsushi S shown in FIG. 4(a),
When processing as shown in FIG. 2(b), in other words, the left side of the sash S is cut at a right angle by a width x1 at a length y from the end face l (hereinafter referred to as right angle cutting), and then the cutting is performed. When cutting diagonally from the surface to the end surface 1 at a plane angle θ1 (hereinafter referred to as diagonal cutting), it was performed in the following manner. First, the sash S is positioned and cut by a rotary blade by a width x1, and then the sash S is rotated by a plane angle θ, positioned, and then cut diagonally with the same rotary blade. Or width x
For cutting No. 1, the rotary blade of one cutting device is used, and when cutting diagonally, the cutting is performed using the rotary blade of another cutting device.

[Problem that the invention seeks to solve]

However, in both cutting methods, the sash S- must be positioned for each right-angle cut and diagonal cut, which results in poor workability and efficiency in sash cutting. Such cutting is usually performed with scribe lines, and therefore, the precision of the cutting dimensions is poor. When cutting twice, the intersections of X and Y do not match, and a step occurs at the intersection, making it extremely difficult to obtain the desired cut shape. This is because the cutting device is equipped with only one rotary blade, and is designed to be used for both right-angle cutting and diagonal cutting. If this is not the case, this is because the cutting devices are divided into two types: one for right-angle cutting and the other for diagonal cutting.

The present invention has been made to solve these conventional problems, and an object of the present invention is to provide a sash processing device that can improve the workability and efficiency of sash cutting.

[Means for solving problems]

The rotary blade is provided with a left-right positioning device that determines the left-right position with respect to the rotary blade.

[Effect]

The horizontal angle of the pair of rotary blades can be set to any desired angle in advance. On the other hand, the position of the sash relative to the rotary blade in the front-rear direction is determined by the front-rear positioning device η, and the position of the sash relative to the rotary blade in the left-right direction is determined by the left-right positioning device. When each position is determined, the longitudinal positioning device is raised by the vertical guide device, and the sash is cut at the arbitrary horizontal angle by the rotationally driven rotary blade.
