B. the point of guiding block 72 and set of rollers R1 is chamfered in expression, this moment paper to separate through three times, can increase bottom paper by set of rollers 62 and 63, and surplus one probability only;
C. represent that paper passes through the crooked path between clearance G 3 and the G4, its crooked kenel is owing to chamfer the non-horizontal phase that guiding block 72 and bumper 73 cause;
D. represent the rough surface of paper in bumper 73, it is to be positioned to chamfer the position on the low side of guiding block 72, to cause one and chamfer the inclined-plane phase place of guiding block 72.But, will on bumper 73, provide an active drag if paper reaches the situation that bumper 73 has dual paper feeding before; Prevention is drawn by overlapping set of rollers 62,63 than the paper of upper strata paper up to bottom;
E. represent paper in the smooth surface that overlaps plate 60, drawn by before overlapping set of rollers 62,63 that paper system keeps the maidenliness state at it.
Operating principle:
When the leading edge of paper on roller R3, behind the roller setting in motion, will be with several paper by G1, its paper number relies parameter such as the surface nature, shape, size of paper to determine.But the design of G1 will allow plurality of sheets of paper pass through simultaneously exactly.Secondly nationality by disengagement gear 9 define width, roller R3 defines the straight line path before paper arrives shell fragment SPI.Because the leading edge boundary of paper is not born whole stacker weight W lock G1 outside in lock G1, this limited number will be by G1, and reaches shell fragment SPI, and pushes to reach and pass through shell fragment SPI.With reference to figure 5, the spring of slight deflection will make the straight line path skew of bottom paper or cause the paper bending distortion, and the generation of this distortion needs external energy, and this energy also stores with paper distortion.
Bottom paper (#1) directly contacts with squeegee, and obtains energy from roller, and these are different with the paper that acts on other non-bottom (#2).The energy system that #2 obtained is produced by the static friction of the paper (#2) of the bottom paper (#1) and the non-bottom; If the energy that produces through static friction overcomes all resistances inadequately, then the paper of the non-bottom (#2) will be blocked in the lock of shell fragment SPI, and with reference to figure 5, it is the free body figure of paper by spring plate SPI.
In a word, want one to reach or many transmission simultaneously, must overcome following each power from the made energy that roller obtained of elastomeric material:
A. the kinetic force of friction that between between paper and paper, relatively moves and produce;
B. the delay power of spring;
C. make the strain energy of spring periphery paper bending;
D. the acceleration/accel of mobile device and deceleration/decel.
Except the paper of the bottom, if the static friction force between each paper will make paper stop paper and carry required less than it; And, when the set down weight of paper is very big,, will produce the situation that paper pinches if can't effectively control because static friction is usually above dynamic friction.
Can't stop plurality of sheets of paper fully based on the SPI on the R3 and open, on R2, establish a repetition lock 3 and make paper control more complete.Remove this, nationality can enter paper front edge the coincidence roller by the made bumper of friction material.
In the paper feeding cyclic process, producing between G1 and G3 has a limited area, so that paper front edge deflection vertically.There is the bevelled rough surface to be designed to be used for alleviating whole stacker Zhang Chongliang or lower paper transfer carrying secretly of process.
Ground of equal importance, provide a roller control setup in above-mentioned limited area, it is a unlatching/park mode, this pattern will provide whole stacker to open and quicken institute's energy requirement, and in the paper feeding cyclic process, provide shock energy, this shock energy is enough to make the several Zhang Songdong on the bottom paper, because the may command motion adds that inductor is so can make the many functions of control except that individual.
The current impulse of Fig. 7 table one driven roller stepping motor, initial current makes stepping motor entry into service, failure of current that stepping motor is stopped.In the gap of G1 and G2, because the effect of SP1 and SP2 separates the leading edge of paper; If operated N unlatching/time-out action,, acceleration and speed-down action separate owing to causing whole stacker to open with bottom paper generation vibrations.Its unlatching/time-out action also will cause system's paper feeding efficient to reduce.Provide a method that can cut the waste paper feeding time at this, promptly utilize the signal between S1 and the S2.In the whole paper feeding circulation, establishing the paper initial weight is W, its pulse count N=N0.Expression is also transmitted and is monitored the continuous impulse number of paper feeding speed by S1 and S2, increases as paper feeding speed, represent to descend the bottom paper to be subjected to less " draw " most, but nationality is widened the minimizing pulse number with pulse time τ; Its net effect is for increasing paper by the speed between G1 and the G2.
More than the present invention is described in detail, described only is preferred embodiment of the present invention, can not limit scope of the present invention.All equalizations of being done according to the present patent application scope change and modify, the scope that all should be still must this creation contains.
