DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a puncher for punching holes in paper.

Prior Art By stopping the paper with a stopper means so as to be located between the punch and the die, and moving the punch almost linearly in the direction of the hole in the die to fit the tip of the punch into the hole in the die. Punchers that punch holes in paper are known.

However, this puncher has the disadvantage that the paper must be stopped.

Purpose An object of the present invention is to provide a puncher that can make a hole in a moving sheet of paper and that can move a punch in a direction perpendicular to the conveying direction of the sheet and place it at a different predetermined position. It's about doing.

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

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 has an acute-angled blade 1b as shown in FIGS. 3 and 4. is formed.
An elastic roller 3 serving as an elastic die 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. This spring clutch 7
A gear 8 is fixed to the outer periphery of the end, and a gear 9 is arranged to mesh with the 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. That is, an engaging protrusion is formed on the inner circumferential surface of the gear 9, and a locking groove is formed in the longitudinal direction of the rotating shaft 9a,
The gear 9 is externally fitted onto the rotating shaft 9a so that the engagement protrusion of the gear 9 fits into the locking groove of the rotating shaft 9a.

Discs 10, 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 disc 10 is moved accordingly, pressing the gear 9 and moving the rotating shaft 9a in the longitudinal direction. The rotating shaft 9a is the drive shaft 11a of the motor 11.
is fixed.

Disposed near the spring clutch 7 is a stopper means 12 for locking the groove in the sleeve 7a thereof.

and a power supply circuit 12e that supplies power to at a predetermined time.

When power is not supplied to the solenoid 12d, the locking hole 12b comes into contact with the sleeve 7a due to the tensile force of the spring 12c, locking the groove of the sleeve 7a, and the sleeve 7a locks with the locking pawl 12b. When the spring clutch 7 is locked, the spring of the spring clutch 7 is loosened, and the connection between the gear 8 and the rotating shaft 2 is released, and the driving force of the motor 11 is not transmitted to the rotating shaft 2, so the rotating shaft 2 is not rotated, so the punch 1 and the elastic Roller 3 is also not rotated.

When power is 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, so that the gear 8 and the rotating shaft 2 are connected by the spring clutch 7, so the driving force of the motor 11 is transferred to the rotating shaft 2.
The rotating shaft 2 is rotated in the direction of arrow a,
