Abstract

PURPOSE:To facilitate boring of punch holes and to enhance the efficiency of sticking operations by movably holding a cylindrical blade, moving the blade vertically while rotating the blade to bore hole and dropping the punched film piece during ascending of the blade. CONSTITUTION:The color sepn. films are placed on a table 22 and are fixed after the reference marks thereof are mated with the indices of magnifying scopes 34a, 34b. The prescribed data of the plates of the respective colors are inputted from an operation panel 36; thereafter, movable members 26a, 26b are moved along guide rails 24a, 24b. A drill 32 is moved along a pole 28 and is mated with the plate of the 1st color. After a locking mechanism is operated, the cylindrical blade of the drill 32 is vertically moved while the blade is rotated to bore the punch hole. Since a stationary pin is provided to the center of the blade, the punched film piece falls onto the punching position. The punch holes are thereafter bored by making the similar operation.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a puncher device for plate making that punches registration holes in each separation plate of a color separation film output from a scanner during pasting work. Regarding.

[Conventional technology]

Conventionally, in pasting work for plate making, after cutting the color separation film output from a color scanner into each separation plate, the first color separation plate, for example M
Attach the plates to the layout using adhesive tape. 1
When all the M plates for one plate have been pasted, they are reversed on a photochrome film, and the retoucher sequentially aligns them with the image of the M plate on the photochrome film while adjusting the register by eye. Paste the Y version, 0 version, and BK version on each Mylar film. In this way, a plate is made from four sheets of Mylar film to which separated plates of each color are pasted.

[Problem to be solved by the invention]

As described above, in the conventional pasting work, a person had to paste each plate one by one in the correct register, which was inefficient and prone to misregistration.

This invention was made to deal with the above-mentioned circumstances,
In order to perform the pasting work efficiently in a short time and with high precision while preventing misregistration, it is an object of the present invention to provide a plate-making puncher device that punches registration holes at corresponding positions in each separation plate of a color separation film. That is the purpose.

[Means to solve the problem]

The plate-making puncher device according to the present invention has a cylindrical blade,
A member that holds this blade so that it can be moved to any position on the table on which the color separation film is placed, a perforating member that moves this blade up and down while rotating it, and a member that is provided inside the cylinder of the blade and that moves the blade up and down. It is sometimes equipped with a pin that drops the perforated film pieces from the blade.

[Effect]

According to this invention, the holes are drilled by moving the cylindrical blade up and down while rotating, so it is possible to drill holes for registration in color separation plates of any size, and the blade moves up and down. Since a pin that does not move up and down is provided in the cylinder, film pieces stuck in the blade after perforation can be dropped when the blade moves over the blade, and the perforation is not affected by the film pieces.

[Example] First, an example of a color separation film will be described with reference to FIG. When the color separation film 10 is output from a color scanner, the color separation film 10 has Y, BK, C, and M for each color original.
4-color separated version 12y.

It is assumed that 12bk, 12c, and 12m are lined up in the vertical direction (in the axial direction when attached to the exposure cylinder of the color scanner) at a period of d. When exposing the pattern of each plate, there is a row of reference marks (register marks) on one side of the pattern that serve as alignment standards.
4y, 14bk, 14c.

14 meters are also exposed at the same time. FIG. 1 shows an example in which color separation plates for three color originals are exposed onto one color separation film.

As shown in Figure 2, each color separation plate has a total of 8 perforation positions P1 to P8, two each on the top, bottom, left and right sides.
Punch holes may be punched at any two of these locations. For example, if punch holes are to be punched in Pl for the Y plate, punch holes are punched at corresponding positions for plates of other colors as well. Then, another punch hole is punched at an arbitrary position selected from P2 to P8, and punch holes are punched at positions corresponding to the Y plate in the same manner for other color plates.

As a result, two punch holes are punched at corresponding positions on the plates of all colors. Similarly, two punch holes are punched at corresponding positions on plates for other color originals. Figure 1 shows PI.

An example of drilling at position P2 is shown. After punching the holes, the color separation film 10 is cut into individual separations.

During pasting work, by pasting separated plates onto each Mylar film using these punch holes as a reference, all color plates can be pasted in exactly the same position.

Next, an embodiment of a puncher device for plate making according to the present invention will be described. FIG. 3 is a plan view, FIG. 4 is a front view, and FIG. 5 is a side view. A table 22 is provided on the desk 20 on which a color separation film as shown in FIG. 1 is placed. The color separation film is arranged in the vertical direction (Y, BK, C,
It is placed on the table 22 so that the direction in which the M plates are lined up is the horizontal direction.

Guide rails 24a, 2 are provided at both left and right ends of the table 22.
4b is provided. Movable members 26a and 26b are provided on the guide rails 24a24b.

The movable members 26a and 26b are manually moved to the guide rod 24a.
, 24b. Guide rail 24 a, 24
Both ends of two poles 2830 perpendicular to b are attached to movable members 26a and 26b. As a result, the movement of the movable members 26a, 26b also causes the poles 28.30 to slide in a direction perpendicular to the guide rails 24a, 24b.

A drill 32 is slidably attached to the pole 28.

The drill 32 is automatically slid along the pole 28 to a desired position by a drive mechanism used in a known drawing machine or the like. The maximum size of the color separation film that can be placed on the table 22 is shown in broken lines in FIG. 3, and the maximum perforated range of the color separation film is shown in dashed lines in FIG.

Although the details will be described later, the drill 32 is constructed by rotating a hollow inner cutter whose cylindrical lower end is shaped into an inverted conical shape and moving it toward the color separation film, as shown in FIG. Drill bunch holes. For this reason, the tip of the blade of the drill 32 must dig into the table 22 to some extent after punching the hole. Therefore, table 2
2 is also perforated to some extent, shortening the life of the table 22 and the blade. In order to prevent this, the color separation film is actually placed on the table 22 with a mount such as cardboard in between. Then, replace this mount as appropriate. Note that instead of the inner cutter, a hollow outer cutter having a cylindrical lower end processed into a conical shape may be used.

The pole 30 has two magnifying scopes 34a.

34b is slidably attached. Magnifying scope 34a
, 34b are manually slid. Magnifying scope 34a, 3
4b are provided with indicators parallel to the ball 30, respectively. When placing the color separation film on the table 22, the magnifying scope 34a.

34b according to the width of the color separation film, and then align one mark in the Y-plate reference mark row 14y, for example, the leftmost mark 14a, and the corresponding most mark in the M-plate reference mark row 14m. Align the left mark 14b with these indicators. As a result, each color separation plate can be positioned horizontally with respect to the ball 28, and the interval between the color separation plates corresponds to the exposure interval in the scanner. In this state, if the drill 32 is moved along the ball 28 at this predetermined interval, the drill 32 will stop accurately at the corresponding position of all the disassembled plates.

An operation panel 36 is provided in front of the table 22.

The color separation plate arrangement period data d is input to the drive mechanism of the pole 28 through the operation panel 36 . Thereby, the drill 32 can be automatically moved along the pole 28 at intervals corresponding to the arrangement of the color separation plates.

The movable member 26b is provided with a locking mechanism, and by operating the lock lever 38, the movable members 26a, 26b are locked.
movement along the guide rails 24a, 24b is prevented.

The color separation film 10 may be fixed to the table 22 with a magnet or adhesive tape, or
The adhesive may be fixed by suction using a suction mechanism (not shown) provided in the.

Next, details of the drill 32 will be explained.

FIG. 7 is a plan view of the drill 32 with the cover removed, and FIG. 8 is a front view showing the left side from the blade 42. Drill 32
has a drill motor 44 whose axial direction is oriented in the vertical direction, and a cam motor 52 whose axial direction is oriented in the front-rear direction. The rotation of the drill motor 44 is transmitted to the blade 42 via the belt 46 and the coupling members 48, 50, causing the blade 42 to rotate. The coupling members 48, 50 transmit rotation and are integrally movable up and down.

A cam motor 52 is provided above the drill motor 44. As shown in FIG. 9, an eccentric cam 54 is attached to the shaft of the cam motor 52, and the rotation of the cam motor 52 causes the cam lever 56 to rotate about a fixed shaft 58. 9th
The figure is a rear view of the cam motor 52 viewed from the ball 28 side, and FIG. 10 is a top view of the cam motor 52. As a result, one rotation of the cam motor 52 causes the other end 56a of the cam lever 56 to move up and down once. The other end 5 of the cam lever 56
When 6a moves downward, it urges the coupling member 62 shown in FIG. 8 downward through the ball member 60. The coupling member 62 is coupled to the coupling member 48 and is normally urged upward by a spring 64. Therefore, one rotation of the cam motor 52 causes the coupling members 62, 48, 50
The blade 42 moves up and down once.

By applying such rotation and vertical movement to the blade 42,
The color separation film is circularly perforated with the same size as the blade 42.

As shown in FIG. 8, a pin 66 is arranged inside the cylindrical blade 42. The upper end of the pin 66 is held by a screw 82
It is supported by. The lower end of pin 66 is above the lower end of blade 42 (when up). Therefore, even if the inside of the blade 42 is clogged with pieces of the perforated film after the blade 42 perforates the film, the film pieces can be automatically removed when the blade 42 returns to the top. If the blade 42 is clogged with film fragments, when punching the hole,
There is a possibility that the perforation position may be shifted due to the film piece, or the perforation may not be perforated in a predetermined circular shape.

Further, a stepped portion 66a is provided on the outer side of the lower portion of the pin 66 at a position where it is joined to the blade 42.

Therefore, by removing the cover screw 82 of the drill 32 and pushing down the upper end of the pin 66, the stepped portion 66 can be removed.
a allows the blade 42 to be removed from the coupling member 42;
The blade 42 can be easily replaced.

A stopper 70 for inhibiting downward movement of the coupling member 50 is provided below the blade 42, and by adjusting the position of the stopper 70 up and down, the drilling depth of the blade 42 can be adjusted. This allows even if the film thickness changes,
The blade 42 always moves by the thickness of the film and does not perforate the cardboard or the like used as a mount.

FIG. 11 shows an adjustment device (see 1) for adjusting the vertical position of this stopper 70.
12 shows a side view thereof, and FIG. 12 shows a plan view thereof.

The stopper 70 has a U-shaped recess surrounding the screw 72,
It moves up and down by rotating the screw 72.

Next, the operation of this embodiment will be explained. First, a color separation film is placed on the table 22, and its reference mark 14a is
, 14b is magnified by a scope 34a.

Fix it according to the mark 34b. As a result, the color separation film and the drill 32 are aligned horizontally. The arrangement period data d of the separation plates of each color in the color separation film is inputted from the operation panel 36.

Next, move the movable members 26a, 26b to the guide rail 24a,
24b, the drill 32 is moved along the ball 28, and the drill 32 is moved to an arbitrary position around the first color separation plate, for example, the Y plate (for example, PI in FIG. 2).
Match. Then, by operating the locking mechanism, the movable member 2
The movement of the guide rails 6a and 26b along the guide rails 24a and 24b is stopped at T. Here, the blade of the drill 32 is rotated and moved up and down to punch holes. As mentioned above, the fixed pin 66 is provided (1) in the center of the vertically moving blade 42, so that the perforated film piece (circular) falls into the perforated position.

After that, move the drill 32 by the width d of one disassembled plate,
Punch holes are punched at corresponding positions around the BK plate, and then punch holes are punched at corresponding positions around the C and M plates in the same manner.

Release the lock mechanism and move the movable member 26a.

26b to align the drill 32 with any other position around the Y plate (for example, P2 in FIG. 2), and then repeat the above operation to the corresponding position on all color plates. 2
punch holes are drilled.

Similarly, two punch holes are punched at corresponding positions on plates for other color originals.

As explained above, according to this embodiment, the drill
After drilling, the drill is moved periodically along the separation plate array at intervals equal to the array period of each color separation plate in the color separation film. Sequential drilling at the stop positions allows registration punches to be punched at precisely corresponding positions around the circumference of each disassembled plate. Therefore, even if the size of the color separation film, the size of each separation plate, and the arrangement format change, punch holes can be punched at arbitrary positions.

Furthermore, since a cylindrical inner blade is used, film pieces after perforation tend to get stuck in the blade, but when the blade rises after perforation,
Since the film piece can be automatically dropped by a pin provided inside the blade, there is no possibility of displacement or deformation of the hole shape due to the film piece stuck in the blade during perforation.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide a puncher device for plate making that punches punch holes for registration at arbitrary corresponding positions around each separation plate of a color separation film.
