Abstract

PURPOSE:To provide such a low-cost bidirectional torque limitter that transmit or cut bidirectional torque according to the size of a load. CONSTITUTION:An outer cylinder 2 is rotatably provided outside of an inner cylinder 1 and a coil spring 3 is provided between both cylinders. A clockwise coil part 3a and a counterlockwise coil part 3b are provided in the coil spring 3. The clockwise coil part 3a is pressed against the inside diameter face 8a of a spring storage cylinder 8 formed on the outside of the inner cylinder 1 and the counterlockwise coil part 3b is pressed against the inside diameter face 7a of a small-diameter hole part 7 of the outer cylinder 2. When the inner cylinder 1 or the outer cylinder 2 is turned in one arbitrary direction, one of the clockwise coil part 3a and the counterclockwise coil part 3b extends its diameter and the other one contracts its diameter. When the load is smaller than the set torque value, the torque is transmitted via the coil springs 3. However, when the load becomes larger than the set torque value, the torque is cut so as not to be transmitted.

The above-mentioned paper feeding device is provided with a pickup roller 21 on a table 20 for supporting the stacked papers P, and a paper feed roller 22 and a paper feed roller 22 in a transfer path of the papers P delivered by contact with the pickup roller 21. A reverse roller 23 is provided below. A one-way torque limiter T is incorporated between the reverse roller 23 and the rotary shaft 24 that supports the reverse roller 23.

Here, the one-way torque limiter T transmits the rotation of the rotary shaft 24 to the reverse roller 23, and when the load applied to the reverse roller 23 exceeds the set torque value of the one-way torque limiter T, the one-way torque limiter T is sent to the reverse roller 23. Cut off the rotation transmission.

In the paper feeding device, the pickup roller 21, the paper feeding roller 22, and the rotary shaft 24 are rotated in the directions of the arrows shown in the figure.

Now, when one sheet P is sent out by the pickup roller 21, the rotation of the sheet feed roller 22 is transmitted to the reverse roller 23 via the sheet P. Since the transmission torque is larger than the set torque value of the one-way torque limiter T, the torque of the rotary shaft 24 is cut off, and the reverse roller 23 moves in the opposite direction to the paper feed roller 22 as shown by the arrow in FIG. Then, the paper P is conveyed forward.

When the paper P is fed between the paper feed roller 22 and the reverse roller 23 in an overlapping state, the friction between the paper P overlapping the paper P is larger than the friction between the paper P and the reverse roller 23. Since it is small, slippage occurs between the overlapping sheets P, and the torque transmitted from the sheet feeding roller 22 to the reverse roller 23 becomes smaller than the set torque value of the one-way torque limiter T. Therefore, as shown in FIG. 4, the reverse roller 23 rotates in the same direction as the rotation shaft 24, and the overlapping lower sheet P is placed on the table 20.
Send it back to the side and convey only one sheet forward.

In the paper feeding device, the torque limiter incorporated between the reverse roller 23 and the rotary shaft 24 is a one-way torque limiter, so that the paper is fed back to the reverse roller 23. When torque is applied, the reverse roller 23 cannot rotate faster than the rotating shaft 24.

Therefore, when a paper jam occurs while the paper P is caught between the paper feed roller 22 and the reverse roller 23, the paper P sandwiched between the paper feed roller 22 and the reverse roller 23 is placed on the table 20. There was a problem that you could not pull out even if you tried to pull out in the direction.
