Abstract

PURPOSE:To make it possible to certainly position each cutter in a short time by forming a positioning device of a display device to digitally display a dis tance from a basic face to the cutter and a positioning caliper which is slidable back and forth and restricted in any motion other than the above-mentioned sliding. CONSTITUTION:When a detector fixing base 10 is moved in the X direction with the observation of value on a display device 14 to attain a position of the value corresponding to a predetermined cutting width, as a caliper 12 is protruded in the Y direction, and moreover the fixing base 10 is fixed, a cutter 19 is abutted on the side 23 of the caliper 12 to be positioned. When the cutter 19 has been positioned, the caliper 12 is moved in a direction opposite to the Y direction to its original position, and the fixing base 10 is moved again in the X direction to a position of the value corresponding to the cutting width assigned to the next cutter 19 to position the cutter 19. After the above- mentioned motion is respected in order to position the last one of the cutters 19, a shaft 21 is expanded to fix the cutters 19 to it. Each of the cutters 19 can thereby be certainly positioned in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a blade positioning device for a spacerless slitter that performs slitting by fixing a cutter to a shaft by an expansion/contraction shaft rib.

<Prior art> In recent years, spacerless slitters using a cutter fixation method using an expansion/contraction shaft have been put into practical use.

However, since this method does not use a spacer, the position of the cutter must be determined within the expansion/contraction axis according to the cutting width. Conventionally, a jig with a caliper-like scale was installed in advance to determine the position of each cutter on a long length, and a jig with a caliper-like scale was installed at several digits of the cutter, and the scale was set on the scale for each cutting width. The cutter was moved to a different location and the position of each cutter was determined according to the position of this scale.

However, it is troublesome to set each scale by looking at a long scale, and it is difficult to align the scales by attaching the positioned scales to the slots and positioning each cutter according to the scale. It takes twice as long to
It was inconvenient O <Problem to be solved by the invention> The present invention attempts to position each cutter reliably in a short time by directly determining the position of the cutters sequentially starting from the cutter on the farthest side. It is something.

<Means for solving the problem> A rail is provided on the entrance or exit side of the slitter parallel to the axis of the slitter, and a positioning device having a reference surface for determining the position of the cutter sliding on the rail is provided. On the other hand, a relative position detection sensor is provided to detect the position of the positioning device, and this detection sensor detects a desired relative position from the reference position, and each cutter is positioned at this position.

<Example> Rails 4 and 6 are provided on the machine bases 1 and 3, and a slide rail 5 is provided on the machine base 2 at the center of both rails.

Wheels 7.9 and a slideway 8 are provided at the bottom of the base 18 to allow for free movement. On the other hand, the slide rail 17 is fixed on the base 18, and the mounting base 10 for the positioning detection device that can be slidably moved on the slide rail 17 by a slideway is provided thereon. A sliding rail 11 is provided on the mounting base 10, and a positioning caliper 12 is attached to the handle 13.
A distance detection rail (e.g. magnetic scale) 16 is stretched along the slide rail 17, and the distance detector 1
5 is provided on the equipment mounting base 17. Also equipment mounting base 1
A display 14 is provided to digitally display a value detected by a distance detector from the left end reference position of the positioning caliper 12 provided at 7. The above is the configuration of the final embodiment.

<Function> When positioning the cutter, the position of the cutter is determined numerically in advance from the reference position according to each cutting width. Next, the cutter is positioned at the numerically determined positions starting from the leftmost click. The method is to first move the detector mounting base 10 in the direction of the arrow X while looking at the numerical value on the display 14 from the reference position of the detector mounting base 10, and then select the desired cutting width corresponding to the predetermined cutting width. When you reach the numerical value, extend the caliper 12 in the Y direction and attach it to the mounting base 10.
While fixing the cutter 19, the cutter 19 is positioned by coming into contact with the side surface 23 of the caliper 12. Once completed, move the caliper 12 in the counter-Y direction and return it, and move the mounting base 10 further in the arrow X direction to the desired value corresponding to the cutting width of the next cutter determined in advance. Then, as in the previous case, the caliper 12 is extended to position the next cutter.

After the final cut is positioned by repeating the above-mentioned operations in sequence, the shaft 21 is expanded and the cutter 19 and the shaft 21 are fixed together.

After positioning all the cutters on either the upper or lower shaft in this way, match the cutters on the other shaft with a gauge, etc., and select an appropriate clearance that matches the plate thickness. As a result, the other cutter positions the stationary cutter in line with the reference, and the cutter positioning work is completed.

<Effects of the Invention> Conventionally, a caliper-like metal fitting was provided for several lengths of the cutter to determine the position of each cutter on a long length, and after positioning it at a position that matched the cutting width, it was attached to a part of the cutter of the slick. After relocating and assembling the cutter, the position of each cutter was determined according to the caliper-like metal fittings, but the 12-fold alignment required time and manpower. The present invention allows the position of the cutter to be determined in one step, and the positioning dimensions of each cutter can be determined by inputting the cutting width, number of cutting lines, plate thickness, trimming width, and plate width into the microcomputer. can be determined, so if the position of each cutter is determined based on this data, the force and position of the cutter can be determined in one operation.
