Separation wheel (separation roller) 21, be positioned at and get paper seat 10 and be arranged at the fixed end 10a place of getting paper seat 10, mainly can be formed by wheel portion 211 and tooth portion 212, wherein, tooth portion 212 is made up of plural grinding tooth, and be arranged at wheel portion 211 sides, make tooth portion 212 in wheel portion 211 and get between the paper seat 10.
In above stated specification, the present invention more can be provided with paper feeding roller (pick roller) 22 in the free end 10b place of getting paper seat 10, when delivery wheel (figure does not show) transmits paper 9 to paper feeding roller 22, via paper feeding roller 22 paper 9 is sent to separation wheel 21 and carries out the paper delivery action.
Postpone gear (delay gear) 30 and be positioned at the side of getting paper seat 10 and being arranged at separation wheel 21, it has plural grinding tooth and engageable in the tooth portion 212 of separation wheel 21, moreover, postpone gear 30 and be provided with projection 31 in the side of plural grinding tooth.
In above stated specification, first ratchet 40 and second ratchet 50 preferably can be single direction ratchet, but it is non-as limit, at this, first ratchet 41 of first ratchet 40 is provided with first abutment face 411 and first dip plane 412, first abutment face 411 is parallel to the axial direction of first ratchet 40 in fact, and is an acute angle between first abutment face 411 and first dip plane 412; Second ratchet 51 of second ratchet 50 is provided with second abutment face 511 and second dip plane, 512, the second abutment faces 511 are parallel to the axial direction of second ratchet 50 in fact, and is an acute angle between second abutment face 511 and second dip plane 512.
The present invention more can comprise: transmission module 60, in order to the propulsion source that provides second ratchet 50 to rotate, it mainly can be made up of delivery unit 61 and driving gear 62, at this, second ratchet 50 can be provided with driven gear 52, and driven gear 52 is engaged in driving gear 62, when delivery unit 61 drives driving gear 62 rotations, drives driven gears 52 rotations and second ratchet 50 is rotated with driving gear 62 simultaneously.
See also shown in Fig. 1, Fig. 2 A, Fig. 2 B, Fig. 2 C and Fig. 2 D, the delivery unit 61 of transmission module 60 continues to drive driving gear 62 and rotates, and drive driven gears 52 with driving gear 62 and rotate and second ratchet 50 is rotated, this moment since first abutment face 411 of first ratchet 40 against second abutment face 511 of second ratchet 50, first ratchet 41 of first ratchet 40 is meshed with second ratchet 51 of second ratchet 50, therefore can drives first ratchet 40 and rotate by second ratchet 50 rotates.When first ratchet 40 rotates, promote to postpone the projection 31 of gear 30 with the wall of its position-limited trough 42, make to postpone gear 30 along with first ratchet 40 rotates and rotates.
At this, because first ratchet 40 drives the power that postpones gear 30 rotations and supports the power of getting paper seat 10 greater than elastic component 11, thereby can to drive the free end 10b that gets paper seat 10 be the center rotation with fixed end 10a, drive paper feeding roller 22 and descend and the contact paper 9 that delivery wheel transmitted, and paper 9 is sent to separation wheel 21 via paper feeding roller 22.
After paper 9 is sent to separation wheel 21, drive 21 rotations of separation wheel via the displacement of paper 9, because the velocity of rotation of second ratchet 50 is driven by paper 9 less than separation wheel 21 rotative speed, therefore second ratchet 50 no longer drives 40 rotations of first ratchet, can get paper seat 10 by the resilient support of elastic component 11, making the free end 10b that gets paper seat 10 is the center spinning reduction with fixed end 10a, and drives paper feeding roller 22 risings, promptly finishes the action of getting paper (pickup).
Get paper (pickup) strength and action specification:
The wheel set occurrence e of this train is
n
Sp: the rotating speed of comber 21;
n
i: the rotating speed of input gear 62;
A: the rotating speed of getting paper seat 10 (swing arm);
Z
62, Z
52, Z
30, Z
212, be respectively the number of teeth of gear 62,52,30 and 212.
● state 1:
● input gear begins to rotate, and this moment, roller 21 contacted because of high friction coefficient with the separation friction lining because of only dividing, and made score end roller and did not begin to rotate both n
Sp=0, get the rotating speed a of paper seat this moment.
e(n
i-a)＝-a
a(e-1)＝en
i
Get rotating speed a＞1 of paper seat, also both having got the paper seat will be with the rotational speed of input gear rotation direction with a, also both shown in Fig. 2 B, gets paper system and begins to get paper.
● state 2:
Paper is driven by pickup roller 22 after getting the paper success, and paper front edge enters comber and divides pinching between the scraps of paper to close district (nip area).Because of the friction coefficient of comber and paper less than comber and divide coefficient so the contained of comber between the scraps of paper to reduce, thereby begin to rotate.
After comber begins to rotate, both n
Sp≠ 0, the rotating speed a ' that get the paper seat this moment becomes:
e(n
i-a′)＝n
sp-a′
a′(e-1)＝en
i-n
sp
Also both, the rotating speed a ' that gets the paper seat when comber begins to rotate is less than comber rotating speed a under the quiescence before this begins to get paper.Also both when comber begins to rotate, elastic component 11 can retract its initial position with getting the paper seat, shown in Fig. 2 D.
This both got the action specification that reaches of paper strength for getting paper system.
See also shown in Fig. 1, Fig. 3 A and Fig. 3 B, when first ratchet 41 of first ratchet 40 is meshed with second ratchet 51 of second ratchet 50, first abutment face 411 of first ratchet 40 can drive first ratchet 40 by 50 rotations of second ratchet by this and rotate against second abutment face 511 of second ratchet 50.When paper 9 drives 21 rotations of separation wheel, because separation wheel 21 is subjected to the velocity of rotation of the rotative speed of paper 9 drives greater than second ratchet 50, therefore the tooth portion 212 that changes by separation wheel 21 drives 30 rotations of delay gear, rotate but not drive delay gear 30 with first ratchet 40, at this moment, the projection 31 that postpones gear 30 pushes the wall of the position-limited trough 42 of first ratchet 40, use and drive 40 rotations of first ratchet, first dip plane 412 of first ratchet 40 is against second dip plane 512 of second ratchet 50, and first dip plane 412 is moved along second dip plane 512 and is made second ratchet 51 of the first ratchet jump out of mesh, second ratchet 50 of first ratchet 40, makes second ratchet 50 no longer drive first ratchet 40 and rotates.After paper 9 leaves separation wheel 21 separation wheel 21 is stopped the rotation, second ratchet 50 is engaged in first ratchet 40 again by rotation, first abutment face 411 that makes first ratchet 40 is once more against second abutment face 511 of second ratchet 50, and makes second ratchet 50 drive first ratchet 40 once more to rotate.Therefore, can reach the function that surmounts (over running) by the disclosed structure of the present invention.
See also shown in Fig. 1, Fig. 4 A, Fig. 4 B and Fig. 4 C, do not drive 21 rotations of separation wheel as yet in paper 9, driving first ratchet 40 with second ratchet 50 rotates, and promote to postpone the projection 31 of gear 30 via the wall of the position-limited trough 42 of first ratchet 40, make and postpone gear 30 along with first ratchet 40 rotates and rotates, drive in delay gear 30 rotation processes at first ratchet 40, another wall of projection 31 the right and position-limited trough 42 is kept θ
1Angle (as shown in Figure 3A).When paper 9 begins to drive 21 rotations of separation wheel, because separation wheel 21 is subjected to the velocity of rotation of the rotative speed of paper 9 drives greater than second ratchet 50, therefore the tooth portion 212 that changes by separation wheel 21 drives 30 rotations of delay gear, in this rotation process, projection 31 comparatively fast produces θ in its left-hand side because of its velocity of rotation
2Angle (shown in Fig. 3 B), and along with it rotates θ
2Angle increases gradually, makes θ up to projection 31 against another wall of position-limited trough 42
1Angle is 0, and the wall of projection 31 left-hand sides and position-limited trough 42 produces θ
3Angle (shown in Fig. 3 C), at this moment, the projection 31 that postpones gear 30 push first ratchet 40 position-limited trough 42 wall and drive first ratchet 40 and rotate, break away from separations wheel 21 and no longer drive 21 rotations of separation wheel up to paper 9.
After paper 9 leaves separation wheel 21, separation wheel 21 no longer drives and postpones gear 30 rotations, make projection 31 transfixions, because continuing to drive second ratchet 50, transmission module 60 rotates, and drive first ratchet 40 and rotate, make the wall of the position-limited trough 42 of the ratchet 40 of winning move closer to the projection 31 that postpones gear 30, up to θ
3Angle be the wall of 0 o'clock position-limited trough 42 once more against the projection 31 that postpones gear 30, promptly can first ratchet 40 drive once more and postpone gear 30 rotations.
In aforementioned process, when paper 9 took turns 21 by separation, the wall of projection 31 left-hand sides and position-limited trough 42 produced θ
3Angle, after paper 9 leaves separation wheel 21, θ
3Angle can be decreased to till 0 gradually, at θ
3Angle reduces during this period of time gradually, and paper feeding roller 22 can't transmit another paper 9 to separation wheel 21, makes two pieces of paper open 9 and draw back the purpose of reaching delay (delay) at interval when transmitting.
The present invention can have the paper of getting (pickup) simultaneously, surmounts (over running) and postpone three functions such as (delay) by simple structure considerably, and not only required component is few, and has advantage cheap for manufacturing cost.In addition, when the present invention opens greatly in paper feeding to be passed, its first ratchet and out-of-gear time of second ratchet are more of a specified duration, open hour in paper feeding to be passed, its first ratchet and out-of-gear time of second ratchet are shorter, no matter to be transmitted paper size why, under the situation of the size that does not change position-limited trough, the transmission that two pieces of paper are opened is equal at interval, thereby not only can promote the convenience of use, need not prepare to have first ratchet of the big or small position-limited trough of difference during manufacturing yet, effectively increase the simple and easy degree of getting the raw materials ready.
Though technology contents of the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; do not breaking away from spirit of the present invention a little change and the retouching done; all should be covered by in the category of the present invention, so protection scope of the present invention is as the criterion when looking the claim person of defining.
