Description
Technical field
The invention relates to a kind of paper-fetching mechanism, particularly the paper-fetching mechanism of more simplifying relevant for a kind of structure.
Background technology
In general, in chopping machine or multifunction machine, all can have automatic deficient paper apparatus, and automatic deficient paper apparatus can include paper-fetching mechanism, paper distributing mechanism, paper advance mechanism and tell mechanism of paper etc.
With regard to present paper-fetching mechanism, it is to adopt the mode of dynamically getting paper to get paper mostly, that is to say, the pickup roller of paper-fetching mechanism can provide suitable downforce in paper at any time, to set up a friction force between pickup roller and paper, pickup roller rotates and can take paper away then.
Fig. 1 is the schematic perspective view that shows a kind of existing paper-fetching mechanism 1.Paper-fetching mechanism 1 mainly includes a CD-ROM drive motor 11, a train of reduction gears 12, a switch 13, one first S. A. 14, a rocking arm 15, one unidirectional mechanism (one-way mechanism) 16,1 second S. A. 17 and two pickup rollers 18.The rotating shaft of CD-ROM drive motor 11 is input end (not shown)s that are connected in train of reduction gears 12, and first S. A. 14 is mouth (not shown)s that are connected in train of reduction gears 12.One end of rocking arm 15 is to be sheathed on first S. A. 14, and its other end is to be sheathed on second S. A. 17.Two pickup rollers 18 are to be individually fixed on the two ends of second S. A. 17, and first S. A. 14 can pass through a drive belt (not show, be positioned among the rocking arm 15) and is connected in second S. A. 17.
As mentioned above, when CD-ROM drive motor 11 runnings, it is a lower rotating speed that its output speed can slow down via train of reduction gears 12 earlier.Then, first S. A. 14 that is connected in train of reduction gears 12 promptly can be with this lower rotational speed, simultaneously, drive by drive belt, second S. A. 17 also can be with this lower rotational speed, at this moment, two pickup rollers 18 that are fixed on the two ends of second S. A. 17 also can be with this lower rotational speed, and thereby drives paper.In addition, rocking arm 15 again can first S. A. 14 do for pivot point and swing up and down so that pickup roller 18 can provide suitable downforce in paper at any time, and then between pickup roller 18 and paper, set up a friction force.
In addition, in most business machine, CD-ROM drive motor 11 or train of reduction gears 12 often also can be connected in the paper-feeding roller of a paper advance mechanism, so switch 13 (for example electromagnetic valve) promptly can be used to switch the rotation direction of CD-ROM drive motor 11.
Below will be applied in the business machine 2 operation of getting paper and paper feed is described with paper-fetching mechanism 1.As shown in Figure 2, get paper sensor 21 when one in the business machine 2 and sense a paper P when existing, CD-ROM drive motor 11 just can turn round and order about pickup roller 18 and get paper according to anticlockwise motion.Then, when paper P passes through a paper feed sensor 22, paper feed sensor 22 just can issue a signal transmitted to switch 13, then, switch 13 promptly can force CD-ROM drive motor 11 to do antiport, and then force train of reduction gears 12 to do reverse deceleration output, at this moment, a paper-feeding roller 23 that is connected in train of reduction gears 12 can be docile and obedient clockwise and be rotated and carry out paper feed.Yet, because pickup roller 18 also is to be connected in train of reduction gears 12, so in order to prevent when train of reduction gears 12 is done reverse deceleration output, can to force pickup roller 18 also to be docile and obedient the clockwise rotation, unidirectional mechanism 16 can have an effect, in other words, because the existence of unidirectional mechanism 16, pickup roller 18 only can be according to anticlockwise motion, rotate and can't be docile and obedient clockwise, so can prevent to be taken out of again after paper P is in entering business machine 2.
As mentioned above, because train of reduction gears 12 normally is made of a plurality of gear, so regular meeting makes paper-fetching mechanism 1 become huge, and then can influences the inner space application of business machine 2, or cause the volume of business machine 2 too huge.Moreover because the existence of train of reduction gears 12, unidirectional mechanism 16 and switch 13, the structure of paper-fetching mechanism 1 is normally quite complicated.
