Problems solved by technology

Therefore, even if braking (short-circuit braking or reverse braking) is applied during high-speed rotation, it will not stop at the same time as braking, but it will be difficult to stop at the reference position due to inertial rotation.

Abstract

Provided is a hole punching apparatus that is capable of improving the accuracy of stopping at a target reference position. The hole punching apparatus executes a hole-punching process and a braking process, and includes a rotation-detecting unit and a brake-control unit. The hole-punching process punches punch holes by rotating a hole-punching shaft from a reference position. The brake-control unit intermittently turns ON and OFF a short-circuit brake in the braking process. The brake-control unit sets a braking period for turning ON the brake according to the rotation position and rotation speed of the hole-punching shaft that is measured based on the rotation-position signal so that the braking period tends to become longer as the rotation position becomes closer to the reference position, and tends to become longer as the rotation speed becomes faster.

Description

technical field [0001] The present invention relates to a punching device for punching holes in recording paper. Background technique [0002] As a punching device for punching a hole in recording paper, there is known a punching tool that punches a hole in recording paper by moving up and down, a motor for punching, and a vertical motion conversion unit that converts the rotation of the motor for punching into the vertical motion of the punching blade. installation. [0003] Usually, punching by a punching device is usually performed in a short time of several tens of milliseconds, and thus is accompanied by a large load fluctuation. Therefore, in typical techniques, many DC motors are used as motors for piercing, but DC motors have a large inertia. Therefore, even if braking (short-circuit braking or reverse braking) is applied during high-speed rotation, it will not stop at the same time as braking, but it will be difficult to stop at the reference position due to inert...
