Electric stapler and operation method thereof

Abstract

An electric stapler is operated by the steps of: a paper bundle pinching step of relatively moving a table part and a driver unit and also pinching a paper bundle; a staple separation step of folding a staple into U-shape by a forming plate and also separating the folded U-shape staple from a staple sheet by moving a driver; a penetration step of penetrating legs of the staple into the paper bundle by further moving the driver; a clinch step of inward folding the legs penetrating through the paper bundle by a clinch device; and a paper bundle releasing step of releasing the paper bundle. A relative movement of the table part and the driver unit, the forming plate, the driver, and the clinch device are powered by a single motor. A driving speed of the motor in the steps excluding the penetration step and the clinch step is slower than the driving speed of the motor in the penetration step and the clinch step.

Description

Technical field [0001] The present invention relates to an electric stapler and a working method of the electric stapler. In more detail, it relates to a paper stack clamping step, a staple cutting-off step, a penetration step, a clamping step, and a paper stack releasing step. An electric stapler that performs binding processing and a motor driving method in an electric stapler. Background technique [0002] Conventionally, there has been known an electric stapler that electrically penetrates a stack of stacked sheets of paper (hereinafter referred to as a paper bundle) with staples to perform the binding operation of the paper bundle (for example, refer to Patent Literature 1, Patent Literature 2, Patent Document 3).

AI Technical Summary

Problems solved by technology

However, if the electric stapler designed to be driven with a voltage of 24V is driven with a voltage of 12V, etc. so that the driving speed of the motor is uniformly slowed down, there will be the following problem: the staple will be penetrated when it is caused to penetrate the stack of paper. The binding performance of the electric stapler (the number of sheets that can be stapled, etc.) decreases due to a decrease in performance, a decrease in the clamping force required to clamp the legs of the staple, etc.

However, if a high-performance motor is used, there are problems in that the price of the electric stapler increases, the number of products increases due to the increase in the types of motors, and the management cost and component cost also increase.

In addition, the method of installing a gear box or a belt speed change mechanism is also considered, but this will also lead to an increase in price and an increase in the number of products

[0012] Furthermore, a method of housing the entire electric stapler in a soundproof box or the like to prevent the driving sound from being transmitted to the outside was also considered, but there was a problem that the size of the product increased.
