Description

479023 V. Description of the invention (1) Field of the invention The present invention relates to a paper picking mechanism, in particular, a paper picking mechanism used in an automatic paper feeding system. BACKGROUND OF THE INVENTION In a printing machine, the automatic photocopying of paper is often required. Power is expensive and the structure is more powerful. Multi-office Automatically take paging feed. The means, the system's electromagnetic complexity is complicated, and how to improve the room business machine paper mechanism is a cantilever paper fetching machine, but outside the conventional motor, its valve or another manufacturing cost exceeds the conventional technology, such as when it is important to carry out In the department system, the cantilever-specific printer with a lack of high-speed operation, a part of which is subsequently listed as an automatic removal with a vertical movement to achieve failure, serious failure, is a facsimile machine 'It is a printing, Paper delivery agencies must provide feedback, so that it will affect the production and development of the film and film, a stack of real and medium one into the use of paper, the main invention of the case of product competition

This case is a paper picking mechanism, which is applied to an automatic paper feeding system that has a system motor that can rotate in a first-side-moving paper feeding system. The paper picking mechanism includes a manual rotation and a first Two sets, driven by the motor of the system; one third pass = shift—the first drive is installed by the friend, and is driven by the first pass

Page 5 479023 V. Description of the invention (2) The belt of the moving device and a third driving device are rotated in the starting position and direction, and the third driving device is actuated, and the third driving device is moved from the top to the third driving device, and then when The external motor received by the device is fed by the first gear and a gear on the paper picking line; one line of the first line and the second line are combined with the one-way transmission shaft to be belt-fitted to the transmission. According to the upper connecting shaft, the second position of the paper pick-up position is subject to the starting position. The second transmission will receive the horsepower of the first system less than the second position of the row. When rotating, the bearing rotates with the second concept, and the moving shaft switches with the cutting device system of the receiving unit to the second drive of the device. The direction of the threshold is turned to the motor of the paper take-up machine. In other words, when the transmission is carried by the transmission, the second external force of the paper machine is transferred with the rotation, and the first position of the external device is greater than the second transmission. The force with a strong position should take the lead. A threshold moving device system is smaller than the first and the third gears, which are connected to the door to make three rotations, so that when the value is actuated and the direction of the threshold is reached, the paper touches the paper pinch value. And the second device is subject to a third transmission; for a first, the first transmission of the belt, the first transmission in the frame structure includes a drive; a transmission shaft, directly connected to the transmission shaft, The horse shaft rotates in the system, and the Dadajinda drive shaft rotates in the system; a paper dividing roller, a sleeve: and a second gear are directly connected to the position. The structure further includes a cantilever, which is a connection between the pivoting transmission device and the third transmission device. The second transmission device in the paper picking mechanism includes: must be connected to the cantilever; a third gear, pivotally fit to

Page 6 479023 V. Description of the invention (3) The connecting shaft is fitted into the second gear in the first transmission device; and a torque limiting module is provided between the connecting shaft and the third gear Only when the external force received by the third gear is greater than the threshold value can it be rotated along the connecting shaft. According to the above concept, the third transmission device in the paper pickup mechanism includes a paper pickup shaft, which is directly connected to the cantilever; a fourth gear is pivotally sleeved on the paper pickup shaft and fits in the second transmission device And the third gear; and a paper picking roller, which is directly connected to the fourth gear and pivotally fits the paper picking shaft, which is the external force received by the third gear when the system motor rotates in the first direction. When it is less than the threshold value, the cantilever is rotated along the transmission shaft by the first direction rotation of the system motor, and the starting position is switched to the paper pickup position so that the paper pickup roller contacts the paper Above, when the reaction force generated after the paper picking roller abuts against the paper causes the external force received by the third gear to exceed the threshold value, the fourth gear and the paper picking roller will be driven by the third gear The paper is moved, and then when the system motor rotates in the second direction and the external force received by the third gear is less than the threshold value, the cantilever is driven along the second direction by the system motor to rotate in the second direction. transmission shaft Rotation, and the reply from the pickup position to the start position so that between the pickup roller and the sheet having a distance.
