Repeat above-mentioned paper collection process, on paper supporting plate 5, just can deposit the paper of some.
Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail.
For solving the technical scheme that its technical matters adopts be: structure is a kind of simple in structure and can reliably solve and when paper is collected, exist curling and collect the restricted device of antiquarian and paper collection system.
As shown in Figure 2, paper collection system is by housing 1, collection belt 3, paper supporting plate 5, coil spring 6, slide rail 7, paper pushing roller 11, paper isolation wheel 10, infrared pickoff composition.
As shown in Figure 6, in the time that paper is collected in needs storage, first, it is conducting state that paper collection system needs initialization infrared pickoff, be that disposal system is sent instruction, contrarotation paper isolation wheel, forces the through hole 16 on infrared pickoff transmitting terminal 8 and infrared pickoff receiving end 9 and paper isolation wheel 10 to be same axle center state, now, infrared signal conducting.Secondly, paper collection system outside belong to other and the sheet transport system that uses with system support on roller set 12 and internal system paper pushing roller 11 simultaneously as shown in Figure 6 direction of arrow subtend rotate, opening 2 by paper 13 on housing 1 transmits into the inside of housing 1, now, collection belt 3 and paper isolation wheel 10 keep motionless.
As shown in Figure 7, when paper 13 advances between the through hole 16 of top of form 13a on infrared pickoff transmitting terminal 8 and paper isolation wheel 10 and shelters from the infrared communication between infrared pickoff transmitting terminal 8 and 9, paper collection system is received the information that infrared signal opens circuit, be checked through its P3.4 pin by micro controller system C8051F584 and level from low to high occurs change and carry out perception, now paper collection system control collection belt 3 and paper isolation wheel 10 continue to keep motionless.In the time that paper 13 advances to top of form 13a and soon approaches the upper surface 5b of paper supporting plate 5, paper collection system control collection belt 3 starts to rotate, now, the common rotation of collection belt 3 and paper pushing roller 11 drives paper 13 to continue to enter in housing 1, in this process, the rotational line speed of collection belt 3 and paper pushing roller 11 is consistent.
The time that paper collection system control belt 3 starts to rotate must be enough accurate, otherwise be easy to occur coil paper.Paper collection system is according to the state variation of infrared pickoff, and then the motor starting time of belt 3 is accurately controlled in time delay.The processing mode of paper collection system: the P3.4 pin of the C8051F584 connecting from infrared pickoff occurred moment of change of voltage from low to high, according to the speed parameter of two-phase stepping motor 27, after rational time delay is set, start stepping motor 27, typical delay time is 100ms.
As shown in Figure 8, paper 13 moves on, infrared communication between infrared pickoff transmitting terminal 8 and infrared pickoff receiving end 9 continues to interrupt, paper collection system control collection belt 3 and the inner paper pushing roller 11 of device are rotated further paper feeding, simultaneously, paper collection system control paper isolation wheel 10 continues to keep motionless, so that paper 13 can continue to enter smoothly housing 1 inside.
As shown in Figure 9, paper 13 moves on, in the time that paper rear end 13b has just exposed the through hole 16 on paper isolation wheel 10, infrared communication conducting between infrared pickoff transmitting terminal 8 and infrared pickoff receiving end 9, paper collection system is checked through by micro controller system the level that the P3.4 pin of C8051F584 occurs from high to low and changes to perceive infrared signal conducting.The level variation moment occurring from high to low at P3.4 pin starts, paper collection system stops the stepping pulse signal of two-phase stepping motor 27, the P1.4 pin that connects " STEP " pin is put no longer input pulse signal, the EN being connected with P3.3 continues to keep low level, and after maintenance certain hour (200ms), EN being set is high level.EN enables control signal makes stepping motor 27 have hold torque, prevents because the stop position inaccuracy that machinery inertial causes.Stop after P1.4 pin input pulse signal at two-phase stepping motor 27, collection belt 3 and the inner paper pushing roller 11 of device stop operating, and now, paper 13 also halts and rests on the position of the infrared communication conducting between infrared pickoff transmitting terminal 8 and 9.
As shown in Figure 10 and Figure 11, after paper 13 paper feeds put in place and stop, the pin parameter of the motor-drive circuit interface 25 of paper collection system configuration singlechip controller 22, P1.4 input pulse " STEP " signal of singlechip controller 22, P3.3 are low level for, P1.6 and P1.7, the P1.5 that DIR connects is low level, starting to illustrate anticlockwise direction by the mode control paper isolation wheel 10 of contrarotation two-phase stepping motor 27 rotates, stir the end 13b of paper 13, paper end 13b is because the effect of the spacer 15 of paper isolation wheel 10 bends.
As Figure 12 and as shown in figure 13, when after 180 ° of paper isolation wheel 10 upsets, paper end 13b is in paper isolation wheel bottom.Now, infraredly send to infrared pickoff receiving end 9 by infrared pickoff transmitting terminal 8 through through holes 16, infrared conducting, singlechip controller 22 perceive its P1.4 pin by high level to low level variation, paper collection system stops the STEP signal input of two-phase stepping motor 27, two-phase stepping motor 27 stops operating, and the EN signal being connected with P3.3 keeps certain hour (200ms) afterwards, and it is that high level is cancelled maintenance that EN signal is set.Now, paper isolation wheel 10 stops the rotation, and keeps motionless.The inclined-plane 3a of paper isolation wheel 10 tops and collection belt 3 forms paper feed space W again, and collection completes.
Due to the elastic force effect of coil spring 6, when paper 13 enters paper collection system, the paper constantly entering is constantly flattened by collection belt 3, can not bend so enter paper collection system and pushed down paper 13 partly by collection belt 3.In the time that paper collection system is collected second paper (as Figure 14), the rear end 13b opening due to preceding sheet has isolated the below of wheel 10 in paper, so, no matter first paper 13 do not pushed down part by collection belt 3 has or not the situations such as curling, all tops in the rear end of first paper 13b all the time of second top of form 13a, second paper, in the time entering paper collection system, all there will not be curling.
