Please refer to Fig. 2, it is the diagram of circuit of a kind of paper-feeding method of a preferred embodiment of the present invention.Fig. 3～Fig. 6 is respectively and uses paper-feeding method of the present invention, the illustrative view between its pickup roller and the paper-feed.
As shown in Figure 2, Paper fetch method of the present invention mainly comprises the following steps: step 1 S110, and pickup roller begins rotation by certain paper position, so that file is by the gap between pickup roller and the feeding box; Step 2 S120 forces file to move along a paper path, and stops file in the crack of paper-feed and mechanism of paper holding; Step 3 S130, the crooked amount of correction file front end, up to pickup roller be returned to decide the paper position till; And step 4 S140, contrarotation paper-feed, and the clamping file is between paper-feed and mechanism of paper holding is with till finishing the paper feed action.
In step 1 S110, pickup roller 210 for example is sheathed in the rotating shaft 212 with positioning cam 220, and rotating shaft 212 can be rotated by the drive of a motor (being) or gear cluster (being), as shown in Figure 3.When paper-fetching mechanism 200 does not carry out any when getting paper action (initial condition), pickup roller 210 is in respectively on certain paper position with positioning cam 220, wherein the purpose of pickup roller 210 is except driving file 20 by the gap between pickup roller 210 and the feeding box 230, more can keep among the less gap P1 of file 20 between pickup roller 210 and feeding box 230, to reach the purpose of locating file 20.In the present embodiment, for example the corner area 216 with a D type pickup roller 210 forms a less clearance P1 between pickup roller 210 and feeding box 230, and particularly this gap P1 is enough to allow file 20 maintain under the in check state.
Then, in step 1 S110, when pickup roller 210 by an initial position (being the document alignment position) when beginning to rotate, rotate one first angle 0 as shown in Figure 4, at this moment, the corner area 216 of pickup roller 210 is disengaged position (as shown in Figure 4) with the surface of file 20, and the gap P2 between pickup roller 210 and the feeding box 230 broadens because of pickup roller 210 rotations one angle.Find that obviously the gap P2 among Fig. 4 between pickup roller 210 and the feeding box 230 is greater than gap, the location P1 between pickup roller among Fig. 3 210 and the feeding box 230.In Fig. 4, when positioning cam 220 and pickup roller 210 rotate one first angle 0 simultaneously, the circular movement of the movable plate 232 of feeding box 230 by positioning cam 220 relatively moves to be got on the paper position for the first time, or pickup roller 210 rotates to first angle earlier with positioning cam 220, the movable plate 232 of feeding box 230 just move to Fig. 4 is got the paper position for the first time afterwards, so that file 20 can be close to the arc-shaped surface of pickup roller 210, be beneficial to get the paper action.
Then, in step 2 S120, for example be covered with rubber 214 or other material of a great friction coefficient on the arc-shaped surface of pickup roller 210, make pickup roller 210 force file 20 to move by the mode of friction of rolling along a paper path, as shown in Figure 5, wherein in the paper feed process, the arc-shaped surface of pickup roller 210 is consistent in fact with respect to the gap between the feeding box 230, and file 20 still is held in the crack of pickup roller 210 and feeding box 230, up to pickup roller 210 be returned to decide the paper position till, as shown in Figure 6.
It should be noted that, in step 2, the front end of file 20 is passing through between paper-feed 202 and mechanism of paper holding 204 shown in known Figure 1A not, but be hampered by paper-feed 202 and mechanism of paper holding 204 go into the paper end, it is as follows that it makes flowing mode: the direction rotation that paper-feed 202 for example advances against file 20 earlier (paper-feed 202 is the clockwise rotation in the present embodiment), so that end is subjected to an opposition and can't advances before the file 20, at this moment, pickup roller 210 still continues clamping file 20 and moves toward paper-feed 202, so that file 20 is in the process of paper feed, carry out the correction of the file 20 crooked amounts of step 3 simultaneously, to trim the front end of file 20, stop up to pickup roller 210, and be returned to and decide till the paper position, as shown in Figure 6.
Then, in step 4 S140, paper-feed 202 opposite spin again (paper-feed 202 is the inverse clock rotation in the present embodiment), i.e. direction rotation of advancing along file 20, pass through between paper-feed 202 and the mechanism of paper holding 204 with clamping file 20, till finishing paper feed action for the first time.Therefore, repeat the paper-feeding method of above-mentioned four steps of the present invention, then can finish continuously and wait the action of file 22 paper feeds for the second time, for the third time, and when carrying out the paper feed action each time, all can proofread and correct the crooked amount of file 20 front ends apace, to prevent that file 20 generations are crooked, to frustrate song or paperboard equally likely possibility and then raising file 20 speed of transmission and fluency.In addition, in the present embodiment, too whether the front end that does not also need to detect file 20 with sensors known (for) deflection.
By above-mentioned explanation as can be known, the present invention frustrates song, crooked, holding paper equally likely possibility because of adopting the paper-feeding method of recoverable document skew amount to prevent file 20 during paper feed.Therefore, various files such as print file such as paper, photograph or fax, duplicating etc., even the file that stiffness is bigger, because of the song of frustrating of the present invention is measured less relatively, so applicable in the paper-feeding method of the present invention, so that file 20 can suitably maintain under the in check state, and finish a series of action of getting paper and paper feed.In addition, when whenever carrying out the action of a paper feed, paper-feed 202 only needs the rotation of clockwise, inverse clock get final product, thus can simplify the operating mode of paper-feed 202 and pickup roller 210, but the also operation reliability of prolonged mechanical itself and durability.
