Below the working process removing paper apparatus 20 is described:

Continue with reference to shown in Fig. 5, rotate the first carrying roller 230 in the counterclockwise direction, rotate the second carrying roller 240 along clockwise direction, by the friction force between the first carrying roller 230 and paper P1, and second friction force between carrying roller 240 and paper P1, paper P1 is transported forward, when transporting paper P1, first carrying roller 230 contacts with the upper surface of paper P1, second carrying roller 240 contacts with the lower surface of paper P1, therefore, not to transport paper P1 by the carrying roller mutually clamped removing in paper apparatus 20, the conveyance of paper P1 is the conveyance under non-cramping state,

Shown in Fig. 5 (b), paper P1 is obliquely along in the process of paper feeding direction B movement, paper P1 can with the first directing plate 250, at least one contact in second directing plate 260, at paper P1 along the first directing plate 250, when at least one in second directing plate 260 moves, directing plate (the first directing plate 250, at least one in second directing plate 260) thrust can be applied to paper P1, due to the conveyance that the conveyance of paper P1 is under non-cramping state, therefore under the effect of this thrust, paper P1 can swing along the direction being parallel to paper P1 place plane, the inclination of paper P1 can be adjusted, when paper P1 moves to the first directing plate 250 and the second directing plate 260 along the downstream end of paper feeding direction B, because the distance between the first directing plate 250 downstream end with the second directing plate 260 downstream end is equal with the width of paper P1, therefore, the upper end of paper P1 can be moved along the first directing plate 250, the lower end of paper P1 can be moved along the second directing plate 260, make the front-end and back-end of paper P1 vertical with paper feeding direction B, thus achieve slant correction is carried out to paper P1,

When removing paper apparatus described in paper P1 has just sent into, remove paper apparatus may depart from perpendicular to paper P1 on paper feeding direction B, namely the symmetric line M of paper P1 not about the first directing plate 250 and the second directing plate 260 is symmetrical, in the drawings for paper P1 closer to the first directing plate 250, in the process of paper P1 along paper feeding direction B movement, because the distance between the first directing plate 250 and the second directing plate 260 reduces gradually, therefore, paper P1 can be close to the first directing plate 250 gradually, the nose angle of paper P1 can push up the upstream plate of the first directing plate 250, because whole paper is also being transported forward by carrying roller, the nose angle withstood on the first directing plate 250 can slide along the upstream plate of the first directing plate 250, and produce resistance counter-force make beyond the first directing plate 250 gradually to the parallel snap of upstream plate (making paper tilt) of the first directing plate 250, when paper P1 moves to the downstream plate of the first directing plate 250 and the second directing plate 260, nose angle near the second directing plate 260 first can push up the second directing plate 260, because whole paper is also being transported forward by carrying roller, the nose angle withstood on the second directing plate 260 can slide along the downstream plate of the second directing plate 260, and produce resistance counter-force make that side near the second directing plate 260 gradually to the parallel snap of the second directing plate 260 downstream plate, because the distance between the first directing plate 250 and the downstream plate of the second directing plate 260 equals the width of paper P1, paper P1 can be symmetrical about the symmetric line M of the first directing plate 250 and the second directing plate 260 in diagram, thus make paper P1 by the position closer to the first directing plate 250, be adjusted to the center between the first directing plate 250 and the second directing plate 260, achieve and location correction is carried out to paper P1.

From the above, removing paper apparatus 20 can while utilizes the first carrying roller 230 and the second carrying roller 240 to transport paper P1, while correct paper P1 under the guiding function of the first directing plate 250 and the second directing plate 260, enable paper P1 be adjusted to tram and do not transport obliquely to paper cutting apparatus, shortening the paper split time.

In the present embodiment, as shown in Figure 4, the first paper feeding track 210 is uneven along paper feeding direction B, and the first paper feeding track 210 comprises: along staggered first arc protuberance 211 and the first arc-shaped depression portion 212 of paper feeding direction B; Second paper feeding track 220 is uneven along paper feeding direction B, and the second paper feeding track 220 comprises: along staggered second arc protuberance 221 and the second arc-shaped depression portion 222 of paper feeding direction B; First arc protuberance 211 is corresponding along paper feeding direction position with the second arc protuberance 221, and the first arc-shaped depression portion 212 is corresponding along paper feeding direction position with the second arc-shaped depression portion 222.First paper feeding track 210, second paper feeding track 220 undulate of the present embodiment can be looked.

Following beneficial effect can be brought: as shown in Figure 5 along the up-and-down first paper feeding track 210 of paper feeding direction B and the second paper feeding track 220, when paper P1 moves along paper feeding direction B between the first paper feeding track 210 and the second paper feeding track 220, paper P1 also can present up-and-down state along paper feeding direction B, make paper P1 laterally (i.e. paper width direction) bending strength reinforcement, therefore, at paper P1 along the first directing plate 250, when at least one in second directing plate 260 moves, the Width of paper P1 is less likely to occur bending or distortion of arching upward (this distortion makes the width dimensions of paper reduce), thus the possibility cannot carrying out location correction and slant correction to paper is decreased, improve and remove the reliability that paper apparatus corrects paper, in addition, the conveyance power of the first carrying roller 230 and the second carrying roller 240 can also be improved.

In a particular embodiment, the first carrying roller 230 is positioned at the nadir place of the first arc-shaped depression portion 212, and the second carrying roller 240 is positioned at the vertex place of the second arc protuberance 221.In this case, the conveyance power of the first carrying roller 230, proportional with the difference of the bending resistance of paper P1 and the gravity of paper P1, the conveyance power of the second carrying roller 240, with the bending resistance of paper P1 and the gravity sum of paper P1 proportional.Be positioned at other positions of the first paper feeding track 210 with the first carrying roller 230, the second carrying roller 240 is positioned at compared with other positions of the second paper feeding track 220, the conveyance power of the first carrying roller 230, second carrying roller 240 is maximum in this case.

In a particular embodiment, the first paper feeding track 210, second paper feeding track 220 is parallel to each other.

In the present embodiment, continue with reference to shown in Fig. 5, first directing plate 250 is divided into the first upstream plate and the first downstream plate (mark), second directing plate 260 is divided into the second upstream plate and the second downstream plate, described first upstream plate, the second upstream plate are oppositely arranged, described first downstream plate, the second downstream plate are oppositely arranged, and the distance between described first downstream plate and the second downstream plate equals paper width, and the vertical distance between described first upstream plate and the second downstream plate reduces gradually along paper feeding direction.In other words, for described first downstream plate, described first upstream plate raises up to the direction away from the second directing plate; For described second downstream plate, described second upstream plate raises up to the direction away from the first directing plate, is that splayed is arranged along the first upstream plate described in paper feeding direction B and the second upstream plate.

In a particular embodiment, the first paper feeding track 210 and the second paper feeding track 220 are in tabular.First paper feeding track 210 has multiple along the spaced opening of paper feeding direction B (mark), and the first carrying roller 230 enters in the interval the first paper feeding track 210 and the second paper feeding track 220 through this opening.Second paper feeding track 220 has multiple along the spaced opening of paper feeding direction B (mark), and the second carrying roller 240 enters in the interval the first paper feeding track 210 and the second paper feeding track 220 through this opening.

Described after-treatment device also comprises: as shown in Figure 2, two are positioned at the both sides up and down of platen carrying surface S and the first paper feed roller 270 of mutual cramping, along paper feeding direction B, first paper feed roller 270 is positioned at removes mechanism of paper 20 downstream, cutting groove 111 upstream, the axis C of the first paper feed roller 270 is all vertical along the downstream end of paper feeding direction B with the first directing plate 250 and the second directing plate 260, direction A is parallel with cutting a sheet of paper.

Shown in composition graphs 1 and Fig. 2, utilize after image processing system 1a forms image on paper P1, paper P1 sends into from paper output E and removes paper apparatus 20.Utilization is removed paper apparatus 20 and is corrected the paper P1 being formed with image, enables the paper P1 being formed with image be adjusted to tram and does not transport obliquely to the first paper feed roller 270, then is transported paper P1 to paper cutting apparatus 10 by the first paper feed roller 270.

Distance between the first directing plate 250 and the second directing plate 260 equals paper P1 width ideally utterly, paper P1 from the first directing plate 250 and the second directing plate 260 out after, the front-end and back-end of paper P1 can be vertical with paper feeding direction B; But, due to the first directing plate 250 with the second directing plate 260 exists manufacturing errors, paper P1 also exists error, the distance be difficult between guarantee first directing plate 250 and the second directing plate 260 equals paper P1 width utterly, can only ensure that the distance between the first directing plate 250 and the second directing plate 260 equals paper P1 width approx.Therefore, paper P1 from the first directing plate 250 and the second directing plate 260 out after, the front-end and back-end of paper P1 can only approx perpendicular to paper feeding direction B.

In order to solve this problem, the first paper feed roller 270 can be registration roller (resistroller).Under the effect of registration roller, the heeling condition of paper P1 can be adjusted, make the front end of paper P1 parallel with the direction A that cuts a sheet of paper.

Wherein, a kind of principle that first paper feed roller 270 corrects paper P1 is as follows: rotate the first carrying roller 230(first carrying roller 230, the carrying roller that second carrying roller 240 middle distance first paper feed roller 270 is nearest, at this for the first carrying roller 230), to the direction conveyance paper P1 towards the first paper feed roller 270, now the first paper feed roller 270 transfixion, if paper P1 tilts, the side of paper P1 front end will first contact the first paper feed roller 270, now paper P1 is stopped by actionless first paper feed roller 270 and cannot move on, because the first carrying roller 230 is still at conveyance paper P1, therefore paper P1 can arch upward, and wait for that the opposite side of paper P1 front end arrives at the first paper feed roller 270, contact first paper feed roller 270 all halts by the both sides of last paper P1 front end, and then reach the effect correcting paper P1.

After paper P1 corrects, the first paper feed roller 270 starts to rotate, to transport paper P1 to paper cutting apparatus 10.

The another kind of principle that first paper feed roller 270 corrects paper P1 is as follows: rotate the first carrying roller 230(first carrying roller 230, the carrying roller that second carrying roller 240 middle distance first paper feed roller 270 is nearest, at this for the first carrying roller 230), to the direction conveyance paper P1 towards the first paper feed roller 270, now the first paper feed roller 270 transfixion, after conveyance a period of time, first paper feed roller 270 starts to rotate, the first paper feed roller 270 be positioned at above platen carrying surface S rotates along clockwise direction, the first paper feed roller 270 be positioned at below platen carrying surface S rotates in the counterclockwise direction, to stop that paper P1 moves on, because the first carrying roller 230 is still at conveyance paper P1, therefore paper P1 can arch upward, and wait for that the opposite side of paper P1 front end arrives at the first paper feed roller 270, contact first paper feed roller 270 all halts by the both sides of last paper P1 front end, and then reach the effect correcting paper P1.

After paper P1 corrects, each first paper feed roller 270 starts to rotate according to the direction with original direction of rotation, to transport paper P1 to paper cutting apparatus 10.

Utilize after the first paper feed roller 270 corrected paper P1, rotate the first paper feed roller 270, to transport paper P1 to paper cutting apparatus 10.By accurately controlling the rotational angle of the first paper feed roller 270, accurately can control the conveying distance of paper P1, paper P1 to be transported the assigned address to paper cutting apparatus 10.The rotational angle that this conveying distance equals the first paper feed roller 270 is multiplied by the radius of the first paper feed roller 270.

For this reason, described after-treatment device also comprises: for controlling the first control device of the first paper feed roller 270 rotational angle, in a particular embodiment, described first control device can be stepping motor.

As can be seen here, the first paper feed roller 270 not only has conveyance paper P1, corrects the effect of paper P1, also has the effect of the conveying distance accurately controlling paper P1.Therefore, when after-treatment device works, not only to control the rotation (comprise and start the moment of rotation, the direction etc. of rotation) of the first paper feed roller 270, also accurately will control the rotational angle of the first paper feed roller 270.

Shown in continuing to see figures.1.and.2, the paper cutting apparatus 10 in described after-treatment device comprises: for the platen 110 of bearing paper P1, and the carrying surface S of platen 110 is provided with cutting groove 111; Can along the cutter 120 of direction A movement of cutting a sheet of paper, in the state of cutting a sheet of paper, cutter 120 be positioned at cutting groove 111, cutter 120 blade towards the direction A that cuts a sheet of paper; Moveable paper-pressing part 130, paper-pressing part 130 can by the both sides (being the left and right sides in Fig. 2) being pressed in cutting groove 111.
