Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for forming a positioning hole for a thin object, and more particularly, to a method for forming a plurality of reference portions of at least one of a positioning reference pin hole and a positioning reference notch. The present invention relates to a method and an apparatus for separately forming a conversion pin hole which fits a positioning pin of an apparatus using the same, on a thin object having the same. A method and apparatus for drilling a matching conversion pin hole in a printing plate.

[0002]

2. Description of the Related Art A thin plate such as a printing plate having a plurality of positioning reference pin holes, a plurality of positioning reference notches, and a plurality of mixed reference portions of the reference pin holes and the reference notches is known.
It is rarely used as it is in an apparatus. Therefore, it is necessary to separately form a conversion pin hole for the reference pin hole or the notch in the printing plate or the thin material, which is adapted to the positioning pin unique to the printing press or other device. For this purpose, a conversion pin hole is formed in a printing plate or a thin plate placed on a base plate having a reference pin that fits and engages with a reference pin hole or a reference notch by using a conversion pin hole punching device.

At this time, a conversion pin hole is drilled with reference to a positioning reference pin hole or a positioning reference notch, as the term implies. However, a plate making machine or a thin material manufacturing apparatus has its own peculiarity (bias, hereinafter the same), and therefore, the reference pin hole or the reference notch also has a peculiarity in the positioning position as a printing plate or a thin material. . On the other hand, a printing press or a device using a thin object has a habit in the position of the positioning pin by itself. It suffices that the two quirks cancel each other out, but as a matter of fact, this case hardly exists and a so-called registering operation is required.

[0004] Therefore, a printing plate or a thin material is actually mounted on a printing machine or apparatus, and test printing or test manufacturing is performed to find deviations in the printed material or manufactured product. Therefore, the position of the conversion pin hole punching device is corrected by the amount corresponding to the deviation with respect to the reference pin hole or the reference pin fitted in the reference notch, and the conversion pin hole is formed again on another printing plate or another thin material.

[0005]

However, especially in the case of a printing plate, the position correction of the conversion pin punching device is a manual operation, even though the required position accuracy is less than 0.02 mm. Therefore, the “dispersion” of the manual work is large, and the test printing is repeated many times. Occasionally, the vise on the printing press is also repositioned.

In the case of a printing plate, in the case of one-color printing, it is sufficient to correct the inclination with respect to the printing medium and the vertical and horizontal displacements.
In the case of multi-color printing of four or more colors, the printing plate of each color must be repeatedly corrected for the position of the conversion pin hole. As can be seen from the above, forming a conversion pin hole for positioning a printing plate or a thin object requires a great deal of labor and a large number of man-hours, which causes a problem of reduced printing productivity and increased cost.

Accordingly, the inventions described in claims 1 to 11 of the present invention have a plurality of reference pin holes or a plurality of reference notches, and sometimes have a mixed reference portion of the reference pin holes and the reference notches.

FIG. 9 is an enlarged sectional view of an alternative example of the modification shown in FIG. 8.

In FIG. 1, a printing plate 1 as a representative example of a thin material has a plurality of, here two, positioning reference pin holes 2, 3 perforated during plate making. The reference pin holes 2 and 3 are
When the printing plate 1 is mounted on a printing press, it serves as a reference pin hole when the conversion pin holes 4 and 5 that match the positions of the other positioning pins of the printing press are formed. The same applies when the thin object 1 is mounted on another type of device. The pin holes 2 to 5 may be circular or oval. In the illustrated example, only the conversion pin hole 4 is oval.

Although not shown, the printing plate 1 (thin plate 1) may be provided with a positioning reference notch for the same purpose as the reference pin holes 2 and 3. The reference notch has a notch shape such as a square shape (square or rectangular), a U-shape, or the like. When a later-described reference pin is fitted and engaged with the reference notch, the reference pin is located at the innermost part of the notch. Sometimes,
There is also a mixed type of the reference pin holes 2, 3 and the reference notch. However, in order to avoid complication here, the printing plate 1 (thin material 1) having the reference pin holes 2 and 3 will be described below as a representative.

2 and 3, the positioning hole forming device 10 is a pin puncher, and the positioning hole forming device 10 is hereinafter referred to as a pin puncher. The pin puncher 10 has reference pins 12 and 13 for individually locking the reference pin holes 2 and 3 of the printing plate 1, and conversion pin hole punching devices 14 and 15 for forming the conversion pin holes 4 and 5.

The pin puncher 10 is provided with a base plate 16 for supporting the printing plate 1, in this example a plate 16 having a flat surface.
Having. The conversion pin hole punching devices 14 and 15 are positioned relative to the reference pins 12 and 13 and fixed to the plate 16. The reference pins 12 and 13 are through holes 17 of the plate 16,
18 The number of projecting reference pins matches the number of reference pin holes. The through holes 17 and 18 are for the reference pin 12,
It has a diameter larger than thirteen. The plate 16 has four legs 19 and four side frames 20 at four corners.

In FIG. 2 to FIG.
Refers to the reference pins 12 and 13,
13c is moved in the direction of a straight line X (indicated by an arrow X at both ends in the figure), and is moved in a direction Y inclined with respect to the line X (indicated by an arrow Y at both ends). The illustrated inclination direction Y is a direction orthogonal to the straight line X.

Here, the printing plate 1 having the reference pin holes 2 and 3 (including the thin material 1) using the pin puncher 10 described above.
Next, the following method is used to form the conversion pin holes 4 and 5 that are compatible with different positioning pins of another device such as a printing press.

That is, the printing plate 1 is locked on the upper surface of the plate 16 through the reference pin holes 2 and 3 of the printing plate 1 through a plurality of, here two reference pins 12 and 13 protruding from the plate 16. Holding this locked state, the plurality of reference pins 1
At least one of the reference pins 2 and 13 is moved by a predetermined distance in at least one of the straight line X direction and the inclined direction (orthogonal direction) Y. The moving distance in the case of the printing plate 1 is 0.
It is in the range of 02 to 3.0 mm.

That is, for the reference pin to be moved,
There are two cases: (1) the case where there is only one reference pin, and (2) the case where there are a plurality of reference pins, in this example, the case of the reference pins 12 and 13. In each case, (3) the reference pin Is moved only in the X direction (left and right directions in the figure), (4) the reference pin is moved only in the Y direction (both the upper and lower directions in the figure), and (5) the reference pin is moved in the X direction and the Y direction. That is, there are three cases;

While holding the stop positions of these reference pin movements, the conversion pin hole punching devices 14 and 15 previously positioned and fixed to the plate 16 with respect to the reference pins 12 and 13 before the movement. Conversion plate holes 4 and 5 in plate 1

The moving direction and the moving distance of the reference pins 12 and 13 are determined by the amount of displacement between the reference pin holes 2 and 3 of the printing plate 1 (thin object 1) and another positioning pin of the printing press (thin object mounting device). In addition, the direction of the displacement is grasped in advance. These "shifts" may be divided into a double-ended arrow X-direction component and a double-ended arrow Y-direction component.

Thus, the displacement of the printing plate 1 (thin object 1) on the printing press (on the thin object mounting device) with respect to the printing medium can be easily and reliably suppressed to less than 0.02 mm. As a result, a high-precision printed matter can be obtained, and a registering operation is not required, so that the printing productivity is greatly improved and the production cost can be reduced.

The head of the male screw has a wrench hole that fits into, for example, a square wrench or hexagon wrench. Alternatively, the male screw may be a wrench head bolt. Although the thread portion may be a coarse thread, a fine thread is suitable for controlling subtle entry and exit of the external thread 41.

As shown in FIGS. 4 and 7, the sliding block 31 located at the support blocks 32 and 33 is
A compression elastic body means 42 is provided for pressing the other wall surface opposite to the external thread 41 of the support blocks 32 and 33 from the concave side.
A pair of compression elastic members 42 are provided on both sides of the male screw 41. The compression elastic body means 42 in this case has a compression coil spring 43 and a pressing bar 44.

In FIG. 7, the compression coil spring 43 is housed in a hole provided in the slide block 31. However, this hole is opened on the other wall side of the supporting blocks 32 and 33 to be pressed, and a seat for the compression coil spring 43 is provided on the side opposite to the opening side. The pressing bar 44 has a body portion housed inside the compression coil spring 43 and a head projecting from the compression coil spring 43. The compression coil spring 43 is disposed between the bottom seat of the hole of the slide block 31 and the head of the pressing bar 44. It is assumed that the compression coil spring 43 has a sufficient pressing force even when the clearance β = 0 to the clearance βa = 0.

On the other hand, as shown in FIG. 5 and FIG.
A compression elastic body means 45 is provided between the sliding block 31 and at least one end face 31es of both end faces 31es of the sliding block 31, in the illustrated example, a left end face 31es. Compression elastic body means 45 in this case

The thread may be a coarse thread, but a fine thread is suitable for controlling the delicate movement of the sliding block 31 in the direction of the arrow X at both ends.

The head 47h of the bolt 47 is
The position is fixed in the direction of the arrow X at both ends. The body of the bolt 47 is housed inside the compression coil spring 46. As shown in FIG. 5, both ends of the compression coil spring 46 are located on the inner surface of the frame 20 and the end surface of the sliding block 31. Also,
As shown in FIG. 8, a seat 49 of the compression coil spring 46 may be provided, which is slidably engaged with the body of the bolt 47. In any case, the head 47h has a wrench hole serving to rotate the bolt 47.

As an alternative, as shown in FIG. 9, the moving mechanism 50 in the direction of the arrow X at both ends is provided with a bolt 47 having a male thread 47s for threading engagement with the thread 48 to be provided at the end of the slide block 31. And a collar 51. Bolt 4

Is located in a range where the rotation of the bolt 47 is not hindered.

As described above, the pin puncher 10 is
Since there are no special parts and a simple structure, the cost is low and the operation is simple. On the other hand, the pin puncher 10 has many types of movement of the reference pins 12 and 13 (details will be described later), has multifunctionality in that sense, and has a size of 0.02 mm.
Therefore, it is possible to form the positioning conversion pin holes 4 and 5 with high precision with respect to the positioning pins of a printing press (other apparatus) using the printing plate 1 (thin plate 1).

Hereinafter, the moving mechanism 3 will be described with reference to FIGS.
A method for forming a conversion punch hole for positioning the printing plate 1 (thin material 1) using the “0” will be described. FIG. 10 is an explanatory view showing the movement of the cross-sectional centers 12c and 13c of the reference pins 12 and 13, respectively.

The external thread 41 of each of the support blocks 32 and 33 is brought into contact with the slide block 31. The two male screws 41 are individually turned independently. Turn the male screw 41
, And the movement is transmitted to the sliding block 31 in opposition to the resistance of the compression elastic means 42.

As a result, the reference pins 12 and 13 are moved in the directions indicated by the arrows Y at both ends. After moving a predetermined distance, the male screw 41
Is fixed. The sliding block 31 is locked at both ends in the arrow Y direction by a compression elastic means 42, and the reference pins 12 and 13 are
The movement stop position is held by the cooperation of the male screw 41 and the compression elastic means 42.

8 and 9, the bolt 47 extending from the frame 20 is turned. The turning of the screw portion 47s of the bolt 47 is transmitted to the sliding block 31, which is elastically supported in the turning direction, as a movement in the direction of the arrow X at both ends via the female screw portion 48.

In the movement shown in FIG. 8, the reference pins 12, 13 are moved in the direction of the arrow X at both ends against the resistance force of the compression elastic means 45. After moving the predetermined distance, the bolt 47 is fixed. The sliding block 31 is locked in the direction of the arrow X by compression elastic means 45 at both ends, and the reference pins 12 and 13 hold the movement stop position in cooperation with the screw portion 47 s of the bolt 47 and the compression elastic means 45.

The movement shown in FIG. 9 is different from the movement shown in FIG.
2, 13 are moved in the direction of the arrow X at both ends. After moving the predetermined distance, the bolt 47 is fixed. The slide block 31 and the reference pins 12 and 13 hold the movement stop position only by the locking of the bolt 47 by the screw portion 47s.

The movement distance of the reference pins 12, 13 in the direction of the arrow Y at both ends is controlled by the total turning angle of the male screw 41. In addition, the reference pin 12,
13 is moved in the X-direction.

Hereinafter, according to FIG. 10, the center of the cross section 12c, 1
The movement of the reference pins 12, 13 will be described with reference to 3c. The basic positions of the reference pins 12 and 13 are indicated by centers 12c and 13c, the upward movement positions in the figure are indicated by 12c-1, 13c-1, and the downward movement positions in the figure are indicated by 12c-2 and 13c-2.

The movement in the Y direction at both ends is indicated by (a) the combination of the center 12c and the center 13c-1, and (b) the center 1c.
Combination of 2c and center 13c-2, (c) center 13c
(D) a combination of the center 13c and the center 12c-2, (e) a combination of the center 12c-1 and the center 13c-1, and (f) a combination of the center 12c-2. Combination with the center 13c-2 is possible.

With respect to the movement in the arrow X direction at both ends, the above-mentioned (a) to (f) are combined with the movement in the arrow X-1 direction, and the movements in the above (a) to (f) are the arrow X-2 direction. Complex movement combining the movements of the two. That is, a total of 12 movement methods are possible except for the basic positions of the reference pins 12 and 13.

If the twelve movement methods are applied to the printing plate 1 (thin plate 1), the conversion pin holes 4 and 5, which are unique to the printing press (other devices), can be formed under high-precision positioning. (Thin 1)
Can be perforated. Moreover, since the adjustment can be made in units of 0.02 mm, the present invention is highly practical. As a result, the printing plate 1 (thin object 1) can be mounted on a printing machine (other device) with high-precision positioning.

In the case of the printing plate 1, a desired high quality can be ensured without any misalignment or color shift with respect to the printing medium. Of course, registering work of the printing plate 1 can be omitted, and adjustment of a portion related to positioning such as a plate vise with respect to a printing press (other device) main body becomes unnecessary, thereby improving productivity of printing and other product manufacturing. Contribute.

However, the amount of displacement between the reference pin holes 2 and 3 of the printing plate 1 (thin material 1) and the conversion pin holes specific to the printing machine (other device) to which they are attached is grasped in advance as vector values. Need to be kept. Therefore, for example, the printing plate 1
(Thin 1) Conversion pin holes 4A, 5 for reference pin holes 2, 3.
A may be perforated, and test printing (test production) may be performed using this to obtain a displacement vector value.
