JPH0699074B2 - Cutler's rhomboid corrector - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a tool for correcting a diamond generated when a paper is cut by a cutter.

(B) Conventional technology When cutting paper with a cutter, some of them are first cut in the flow direction by a slitter, but the occurrence of diamonds is a delicate flow of the paper that mainly occurs between the slitter-feed roll-slider. Due to the shift, the cutter timing in the width direction and the approach angle of the web cutter with respect to the cutter shift, which is slightly different for each row. When correcting the diamond generated in this way, change the bed position to correct the position of the turning roll and change the timing at which the upper blade of the turning roll cuts the paper in the width direction, or the slider after the feed roll. A method of changing the cutter timing and the approach angle of the web was adopted by raising the web by placing paper on the section.

(C) Problems to be Solved by the Invention In the above-described conventional method for changing the bed position, the method for changing the bed position changes the cutter timing over the entire width of the web to change the position of the turning roll. It is not possible to use it on the paper machine on-cutter because the cutter needs to be stopped after each correction by the method of generating a new subtle rhombus in the row that has not been done and lifting the web by placing paper etc. There was a problem.

(D) Means for Solving the Problems In the present invention, the slider portion is provided with a number of spatulaes in the width direction, and a rhomboid rod that can be fixed by a stand attached to the bed is provided. A screw that can be used is cut so that it will be in the same position as the spatula when the rhombus is fixed to the stand.If a rhombus occurs in a certain arrangement, remove the rhombus from the stand and screw the lobe where it occurs. Insert the bolt into the box, insert the rhomboid and push the spatula upward to change the cutter timing and the angle at which the web enters the cutter to correct the rhomboid, without affecting other arrangements. The feature of the paper machine on-cutter is that it is possible to easily correct diamonds.

(E) Embodiment An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a large number of spatula 5 (hereinafter referred to as rhomboid spars) are fixed to the slider 4 at regular intervals. Number of Hishibera 5 is 30
Approximately 80 mm is sufficient, and preferably 50 mm intervals are determined based on the cutting pattern and adjustment effects. The size of the rhomboid 5 is about 50 mm in the width direction, and the length in the flow direction is the lower blade cover.
It only needs to come in contact with 10, and may be changed as appropriate depending on the degree of adjustment and the shape of the machine. The rhomboid correction rod 6 (hereinafter referred to as a rhomboid rod) is attached by a rhomboid stand 7 fixed to the bed 9 so as to enter the lower portion of the rhomboid blade 5. Diamond bar 6
Can be attached and detached while the cutter is in operation. To attach it, insert it in parallel from the side of the rhombus stand 7, and to remove it, perform the opposite operation. A diamond bar stopper 15 is attached to fix 6. The diamond rod 6 has a screw 14 (hereinafter referred to as a diamond screw fixing groove) cut therein, and a bolt 16 (hereinafter referred to as a diamond screw) can be screwed into the diamond rod 6. The arrangement is such that when the rhombus 6 is attached to the rhombus stand 7, it comes directly under each rhombic blade 5, and the rhombic screw 5 inserted at a predetermined position pushes the rhomboid 5 upward. You can The diamond screw 16 is set to an arbitrary height by the diamond screw holding nut 17 without changing its height.

The rhombus stand 7 has the structure shown in FIG. 4, and is designed to support the rhombus 6 over the entire width. The rhombus 6 is supported by the stand groove 19 while the rhombus screw 16 is attached. It can be inserted into 7 and fixed.
When fixing the diamond rod 6 to the diamond rod stand 7 with the diamond screw 16 attached to the diamond rod 6, the diamond screw 16 is in the position of the stand groove 19 only by inserting the diamond rod 16 in the horizontal direction. Then, the diamond screw 16 is not in contact with the diamond latch 5, and if the diamond rod 6 is slightly rotated in the flow direction, the diamond screw 16 will be a diamond screw stopper.
The rhomboid 6 main body is fixed by tightening the rhombus cap screw 8 while keeping a certain angle by the contact between the stand stopper 18 and the rhombus stopper 15.
16 comes into contact with the rhomboid 5 and pushes it up.
When pulling out the rhombus 6, the operation opposite to the above may be performed.

The material of the rhombus 6 is not particularly limited as long as it has a rigidity that does not hinder the work when the rhombus 6 is attached to and detached from the rhombus stand 7. Also, the material of the rhomboid is rhombic screw 16
There is no particular limitation as long as it does not deform even if it is pushed up for a long period of time, and has flexibility and resistance so as to maintain the original shape even when returned to the normal position.

(F) Advantageous Effects of the Invention According to the present invention, as shown in FIG. 5, the diamond screw 16 fixed to the diamond bar 6 pushes up the diamond trapezoid 5 to change the approach angle and the cutter timing of the paper web cutter. By doing so, you can correct the rhombus, and by adjusting the rhombic screw holding nut 17 to finely adjust the height of the rhombic screw 16, you can finely adjust the push-up height of the rhomboid spatula 5. Subtle corrections are possible. In addition, since the rhomboid 5 and the rhomboid screw fixing groove 14 are attached in a large number in the width direction, even if the rhombus 5 cannot be corrected just by adjusting the height of one lobe 5, It can be applied to the paper machine on-cutter in that the rhomboid correction can be done by adjusting the adjacent rhomboids 5, and the rhomboid correction can be done independently for each train, and even while the machine is in operation. It has a very wide range of applications.

Claims (1)

[Claims] 1. A slider provided after a feed roll that guides a web to a cutter is provided with a number of spatulaes at regular intervals in the width direction, and a stand is provided on the bed so that the rhomboid can be introduced under the spatula.
