Description

  The present invention relates to a kind of paper feed mechanism, and more particularly to a paper feed mechanism applied to office equipment such as a multi-function office machine and a scanner.

  As shown in FIG. 8, a paper feed mechanism applied to office equipment such as a multi-function office machine and a scanner includes a paper feed mechanism and a paper feed mechanism, and the paper feed mechanism includes a paper feed motor 71 and a paper feed motor. The paper supply mechanism includes a paper supply motor 81, a paper supply motor 81, a paper separation roll 82 and a paper supply roll 83 driven by the paper supply motor 81.

  When paper supply is required for the office equipment, when there is no paper in the paper supply roll 83, the paper supply motor 81 drives the paper supply roll 83 to take in the paper and drive the paper separation roll 82 to supply the paper. In addition, the paper feeding roll 72 is driven by the paper feeding motor 71 to complete the paper feeding.

  When there is paper in the paper supply roll 83 (that is, the extra paper that was taken in when the paper was taken in the previous time, and the paper supply roll 83 in the paper supply roll 83 part by a paper holding mechanism (not shown) in front of the separation roll 82) The paper feed motor 71 drives the paper feed roll 72 to feed the paper. At this time, the paper supply motor 81 needs to be driven, so that the paper can be separated by the paper separation roll 82, so that one sheet of paper can enter the office equipment.

  However, in such a paper feeding mechanism, the paper separation roll 82 and the paper supply roll 83 are driven by the paper supply motor 81 to rotate at the same time and stop at the same time in the paper feeding process. When there is extra paper taken in during paper feeding, the paper feed motor 71 continues to drive the paper feed roll 72 to feed paper, and the paper supply motor 81 is newly activated to drive the paper separation roll 82 to separate the paper. I have to let it. During this process, the rotation speeds of the paper feeding roll 82 and the paper feeding roll 72 are different, so that the paper keeps a certain gap. In addition, the paper feeding roll 82 forms a time delay from paper feeding to acceleration. Therefore, the paper entry gap becomes large, and the paper feeding speed becomes slow.

  An object of the present invention is to overcome the shortcomings in the existing technology described above, and to provide a paper feeding mechanism with few parts, a reasonable structure, and good work performance.

  In order to achieve the above object, a paper feed mechanism provided by the present invention is attached to a casing and includes a paper feed mechanism, a paper feed mechanism, a paper feed mechanism, and a one-way clutch transmission mechanism.

  The paper supply mechanism includes a paper supply motor, a paper supply roll shaft driven by the paper supply motor, and a paper supply roll attached to the paper supply roll shaft.

  The paper feeding mechanism includes a paper feeding motor, a paper feeding roll shaft driven by the paper feeding motor, a paper feeding roll attached to the paper feeding roll shaft, and a paper feeding gear attached to one end of the paper feeding roll shaft. Include.

  The paper separation mechanism is driven by the paper feed motor and includes a paper separation gear, a paper separation roll shaft attached to the paper separation gear, and a paper separation roll attached to the paper separation roll shaft.

  The one-way clutch transmission mechanism includes a one-way bearing, a swing arm, a recovery elastic part, and an adjustment gear, and the one-way bearing is fitted to the rotation shaft of the paper supply motor, and one end of the swing arm is The one-way bearing is attached to the rotation shaft of the paper supply motor, the other end is rotatably attached to the casing, the recovery elastic part is attached between the swing arm and the casing, and the adjusting gear is It is attached to the other end of the swing arm and meshes with the paper feeding gear and the separating gear.

  In summary, the paper feed mechanism of the present invention is such that the paper feed motor simultaneously drives the paper feed roll and the paper feed roll to rotate continuously until the paper feed roll accelerates from a stationary state and reaches the target rotational speed. Time wasted, gaps between papers were reduced, thereby increasing paper feeding speed, fewer parts, reasonable structure, and good work performance.

The specific operation principle of the paper feed mechanism of the present invention is as follows.
When the scanner needs to feed paper: the paper feed motor 11 continues to rotate along the direction A shown in FIG. 1, and the paper feed roll 14 and the paper feed gear 15 are driven to continue along the direction A. Rotate to allow paper to enter.

  When there is no paper in the paper supply roll 233, the paper supply motor 21 reverses in the direction opposite to the A direction, drives and reverses the driven belt roll 24, and further, the tooth portion 241 of the driven belt roll 24 is moved to the paper supply gear. 231 and thereby the paper supply roll 233 is rotated along the direction A to take in the paper.

  The swing arm 43 and the one-way bearing 41 rotate at the same time, and the one-way bearing 41 rotates only in the A direction. As a result, at this time, the one-way bearing 41 is stationary and the other end of the swing arm 43 has a recovery elasticity. The position limit plate 435 is in contact with the upper end of the open groove 55 under the action of the component 44, and the adjustment gear 45 is engaged with the paper feeding gear 15 and the separating gear 31, whereby the paper feeding motor is fed to the paper feeding gear. 15 is driven to rotate along the A direction, and the adjustment gear 45 is driven to thereby drive the separation gear 31 to rotate along the A direction, thereby causing the paper supply roll 233 to acquire the paper. Then, the paper feed rolls 14 are entered one by one.

  Further, when the buffer area is full in the scanner, the paper feed motor 11 rotates in the direction opposite to the A direction, thereby driving the paper feed roll 14 to rotate in the direction opposite to the A direction. Remove the paper.

  The paper supply motor 21 rotates along the A direction, drives the one-way bearing 41 to rotate along the A direction, and thereby drives the swing arm 43 to rotate along the A direction. The other end of 43 is swung downward by a certain angle, the position limiting plate 435 slides to the lower end of the open groove 55, the adjustment gear 45 is separated from the paper feeding gear 15 and the paper separating gear 31, and the paper separating roll 33 stops rotating. To do.

  At the same time, the paper supply motor 21 drives the paper supply roll 233 to rotate it in the direction opposite to the direction A, thereby attaching the paper and withdrawing it from the paper feed mechanism.

  When the scanner feeds paper again, the paper feed motor 11 rotates along the direction A, and the paper feed roll 14 is driven to feed the paper. The paper supply motor 21 rotates in the direction opposite to the A direction, the one-way bearing 41 stops, and the swing arm 43 rotates in the direction opposite to the A direction under the action of the tension elastic force of the recovery elastic component 44 to return. Then, the position limiting plate 435 slides to the upper end of the open groove 55, that is, the adjustment gear 45 is meshed with the paper feeding gear 15 and the paper separating gear 31 again.

  The opening groove 55 restricts the rotation angle of the swing arm 43 to prevent the swing arm 43 from falling off due to excessive downward rotation, and the swing arm 43 rotates upward under the elastic action of the recovery elastic component 44, and the paper feed gear 15 and the separation gear 31 are prevented from becoming too tight.

  In summary, the paper feed mechanism of the present invention is driven by the paper feed motor 11 and simultaneously rotated by the paper feed motor 11 by the one-way clutch-type transmission mechanism, so that the paper feed roll 33 is kept stationary. It prevents wasting time from accelerating to the target rotational speed, reducing the gap between papers and increasing the paper feed speed. As a result, the paper feed mechanism of the present invention has few parts, a reasonable structure, and good work performance.
