Description

[Detailed description of the invention] Technical field The present invention relates to a puncher for punching holes in paper.

Prior Art A paper sheet is stopped by a stopper so as to be located between a punch and a die, and the punch is moved substantially linearly in the direction of a hole in the die to fit the tip of the punch into the hole in the die. A puncher that punches holes in paper is known.

However, this puncher has the disadvantage that the paper must be stopped.Objective of the present invention is to be able to punch holes in moving paper, and to move the punch in a direction perpendicular to the paper transport direction. An object of the present invention is to provide a puncher that can be moved and placed at different predetermined positions.

Configuration Next, the present invention will be explained in detail based on the illustrated embodiment.

In FIG. 1, reference numeral 1 indicates a punch.

The base of the punch 1 is fixed to a rotating body, for example, a rotating shaft 2. As shown in FIG. 4, the punch 1 has a hole 1a that opens on the tip surface, and the tip of the punch 1 [ii] has an acute-angled blade 5 as shown in FIGS. 3 and 4. 1b is formed.

An elastic roller 3 having elasticity is arranged near the punch 1 at a predetermined distance therebetween.

These elastic rollers 3 are made of rubber or synthetic resin so that their outer peripheries have elasticity, and are fixed to the rotating shaft 4.

Gears 5 and 6 are fixed to the ends of the rotating shafts 2 and 4, and these gears 5 and 6 mesh with each other. A spring clutch 7 is provided at the end of the rotating shaft 2.

A gear 8 is fixed to the outer periphery of the end of this spring clutch 7, and a gear 9 is disposed at 5 to mesh with this gear 8. This gear 9 is attached to the rotating shaft 9a so as to be rotatable integrally therewith and movable in the longitudinal direction of the rotating shaft 9a. In other words, an engaging projection is formed on the inner peripheral surface of the gear 9, and a locking groove is formed in the longitudinal direction of the rotating shaft 9a, and the engaging projection of the gear 9 is formed on the inner peripheral surface of the rotating shaft 9a. A gear 9 is externally fitted onto the rotating shaft 9a so as to fit into the locking groove.

Discs 10 and 10 are fixed to both sides of the gear 8, and the outer peripheries of these discs 10 protrude from the outer periphery of the gear 8 and are located on both sides of the gear 9. When the rotating shaft 2 is moved in the longitudinal direction, the disk lO is moved accordingly, pressing the gear 9 and moving the rotating shaft 9a in the longitudinal direction.

The rotation shaft 9a14 is fixed to drive the motor 11 @11aK.

Disposed near the spring clutch 7 is a stopper means 12 for locking the groove of the sleeve 7a. This stopper means 12U, a locking claw 12b with one end movably provided on the support shaft 12alC1!21
and a tension spring 12c that urges the locking pawl 12b toward the sleeve 7a of the spring clutch 7.
a solenoid 12d for rotating the locking pawl 12b in a direction away from the sleeve 7a;
d and a power supply circuit 12e that supplies power at a predetermined time.

If the above solenoid 12dK power is not supplied,
The locking pawl i2b comes into contact with the sleeve 7a due to the tensile force of the spring 12c and locks the groove of the sleeve 7a. When the sleeve 7a is locked by the locking pawl 12b, the spring of the spring clutch 7 is loosened, so that the gear 8 and the rotating shaft 2 are disconnected and the driving force of the motor 11 is not transmitted to the rotating shaft 2, so the rotating shaft 2 is not rotated and the punch 1 and the elastic roller 3 are also not rotated.

When power is being supplied to the solenoid 12d, the actuator of the solenoid 12d rotates the locking pawl 12b in a direction away from the sleeve 7a against the tensile force of the spring 12c. are connected by the spring clutch 7, so the driving force of the motor 11 is transmitted to the rotating shaft 2 and the rotating shaft 2 is rotated in the direction of arrow a, and the rotational force of the rotating shaft 2 is rotated by the gear 5.6. The rotation shaft 4 is transmitted to the shaft 4, and the rotation shaft 4 is rotated in the direction indicated by the arrow, and the punch 1 and the elastic roller 3 are rotated in the directions indicated by the arrows a and b in synchronization.

When the punch l and the elastic roller 3 are rotated in the directions of arrows a and b, the blade 1b at the tip of the punch l comes into pressure contact with the outer peripheral surface of the elastic roller 3 as shown in FIG. The punch 1 and the elastic roller 3 are arranged so as to bite by a predetermined value of 0.111 to t mm. When the punch 1 and the elastic roller 3 are rotated synchronously in the directions of arrows a and b, that is, the opposing portions move in the direction of conveyance of the paper 13 conveyed between them, the punch 1
The blade 1b at the tip of the paper 13 cuts a predetermined portion from the paper 13 by pressing the paper 13 against the elastic roller 3.
Make a hole in 3.

Conveying roller 14.1 at a predetermined distance from the punch 1
5 is placed. These transport rollers 14.15
ti, the paper 1 that is pressed and inserted between them
3 is held between the punch 1 and the elastic roller 3. These punch l and elastic roller 3 paper 1
Conveyance rollers 16 and 17 are also arranged on the conveyance direction side of 3.

These conveyance rollers 16.17 are also pressed against the paper 1 conveyed by the above-mentioned conveyance rollers 14.15.
3 is carried in a state where it is held between the two.
