Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a rotary cutting paper rotating device in a cutting machine.

<Problems to be solved by the present invention> Conventionally, the cutting of a sheet bundle by a cutting machine is performed after cutting one side.
Manually pull the front of the stack of trimmed paper out onto the table 90
This is a heavy labor because the cutting paper bundle is large and thick because it has been duplicated that the next cutting edge is turned toward you and pushed back to the rear table again and cut according to the required dimensions. In addition, it is not only inefficient, but there is a problem that it is dangerous because it is a work to pass under the cutter blade for cutting. The present invention is intended to solve these problems.

<Structure of the Invention> The present invention lays a horizontal horizontal frame on a rear table of a cutting machine, and provides a moving body that horizontally moves back and forth and left and right in the horizontal frame, and vertically moves and horizontally rotates under the moving body. There is provided a rotating device for rotating a cutting paper in a cutting machine, characterized in that a sandwich clamp for a bundle of cutting paper is attached.

<Example> An example will be described below with reference to the drawings.

A horizontal frame 5 having a rectangular shape in a plan view, which is supported by a frame 3 and rear columns 4a and 4b in parallel with the rear table 2 of the cutting machine 1.
Erection. Two rail bars 6a and 6b parallel to each other are stretched in the middle of the front beam 5a and the rear beam 5b of the horizontal frame body 5, and
Providing a horizontally long rectangular frame 7 that fits in a and 6b and moves forward and backward,
A moving body 9 that moves to the left and right is fitted by being fitted to rail bars 8a and 8b that are stretched in parallel in the middle of the left and right side frames 7a and 7b of the square frame body 7. 10 is a motor for moving the rectangular frame 7 forward and backward, 11 is the same, tensioning chain, 12 is the same, sprocket,
Reference numeral 13 is a motor for moving the movable body 9 to the left and right, 14 is the same, a stretched chain, and 15 is a sprocket. Below the moving body 9, a vertically movable plate 17 is vertically installed which is vertically movable by expansion and contraction of two vertically arranged air cylinders 16a and 16b. Reference numerals 18 and 18 are guide bars with auxiliary springs 18a provided on both sides of the air cylinders 16a and 16b, respectively. A motor 19 is attached downward on the vertical moving plate 17, and a rotary shaft 19a of the motor 19 protruding below the vertical moving plate 18 supports the rotary plate 20. Two air cylinders 21a and 21b are provided on the lower surface of the rotary plate 20.
With the air cylinder 21a,
Downward sandwiching clamps 22a and 22b are attached to the respective ends of 21b. Reference numerals 23a and 23b are guide bars for the sandwich clamp.

An extruding mechanism 25 for the cut sheet bundle a is provided on one of the side gauges 24, 24 (on the right side in the embodiment) on both side surfaces of the rear table 2. The push-out mechanism 25 is an air cylinder 26 that is horizontally mounted outside the side gauge 24, and push-out pieces 27 and 27 that are projected by sliding the air cylinder 26 on the rear table 2 inside the side gauge 24 without any gap. It is composed of

Push the side edge against the right side gauge 24 and back gauge
A sheet of cut paper a whose front side has been cut by dimensioning 28 (FIG. 4a) first creates a space between it and the side gauge 24 by the extrusion of the extrusion mechanism 25 (FIG. 4b). After the back gauge 28 is retracted, the square frame 7 is moved forward by the activation of the motor 10, and the movable body 9 is moved to the right by the activation of the motor 13 to align the movable body 9 with the center of the sheet of cut paper a. , The air cylinders 16a, 16b are extended to lower the vertical moving plate 17 and the rotary plate 20, and the air cylinders 21a, 21b on the lower surface of the rotary plate 20 are expanded / contracted to be cut by the sandwiching clamps 22a, 22b vertically installed at the tips. Both sides of the center of the bundle a are clamped and held (Fig. 4c). The cutting paper bundle a is moved to the center of the rear table 2 by the reverse operation of the moving body 9 and the rectangular frame body 7, and then the motor 19 is activated to move the cutting paper bundle a 90 degrees to the right or left,
Alternatively, it is rotated by 180 degrees so that the next cutting edge of the sheet of cut paper a is directed to the front (Fig. 4d). After releasing the sandwiching clamps of the sandwiching clamps 22a, 22b, moving the rotary plate 20 upward and waiting at the starting position, the sheet bundle a is abutted against the side gauge 24 as in the procedure for cutting the first cutting edge. At the same time, the back gauge 28 is moved forward to give a predetermined size and the front cutting edge is cut. The position of each movement is automatically controlled by a limit switch (not shown).

By repeating the above-mentioned operations, the required side of the cut sheet bundle a is cut and finished. Depending on the size of the sheet of cut paper a, if the central side surface of the sheet of cut paper a cannot be clamped and held in one step, a step of clamping and pressing again in the middle of the work may be added.

FIGS. 5a, 5b, and 5c show another embodiment in which a mechanism 29 for moving one or both side gauges 24, 24 under the rear table 2 to open both ends of the rear table 2 is provided. , Fifth
FIG. A shows an example of a mechanism in which a side gauge 24a fixed to a hinge 31 is supported by an air cylinder 30a mounted under the rear table 2 so that the side gauge 24a is pivoted, swung and retracted.
Shows an example of a mechanism in which the side gauge 24b is supported by an air cylinder 30b which is vertically mounted under the rear table 2 so as to be retracted to the descending lower position, and FIG.
An example of a mechanism in which 24c is supported by an air cylinder 30c that is horizontally mounted under the rear table 2 and is retracted to a horizontal side position is shown.

After the cut sheet bundle a is abutted and cut, the side gauge 24 is retracted from the upper surface of the side end of the rear table 2 and opened, so that a space into which the sandwich clamp 22a enters is formed on the abutting side surface of the cut sheet bundle a. Therefore, the pushing mechanism 25 provided in the side gauge 24 in the previous example is unnecessary. Further, when a mechanism 29 for retracting the side gauges 24, 24 to open the side surfaces is provided on both sides of the rear table 2, as shown in FIG. 6, a cutting device having a diagonal distance larger than the width of the rear table 2 is used. The sheet bundle a can be rotated.

<Effects of the Invention> According to the present invention as described above, it is possible to automatically rotate the cut sheet bundle having one side cut on the rear table to perform the turning operation on the other side. There is an effect that the work efficiency can be remarkably improved such that the next turning-off process can be set while the sheet bundle on the front table is processed by half-cutting. In addition, there is no step of passing under the cutter blade for cutting, so that there is an effect that work safety can be improved.
