The specific embodiment
Fig. 4 to 6 is respectively three-dimensional exploded view, lateral plan and the three-dimensional combination figure of expression according to the paper distributing mechanism of first embodiment of the invention.As shown in Figs. 4-6, the paper distributing mechanism of present embodiment is combined on the main body 3, and comprises paper-feeding roller 2 and comber 1.Comber 1 comprises sleeve 10, axis body 20, torsion limiting member 30 and two friction wheels 40.
Paper-feeding roller 2 is rotated by drive power source, and then applies external force to two friction wheel 40 and axis body 20, and desire rotates two friction wheels 40 and axis body 20, and pressure makes said comber pressurize to said paper-feeding roller.
In this example, can utilize the deadweight of comber 1 that comber 1 is pressed on the paper-feeding roller 2.Perhaps, this paper distributing mechanism can also comprise compression spring 50, the housing of its contact comber 1 and paper distributing mechanism, in order to impose aforementioned pressure so that comber 1 to paper-feeding roller 2 pressurizations.
Except above-mentioned pressuring method, can also use the 60 pairs of arms 12 of torsion spring that are connected to hollow circuit cylinder 14 and housing to apply that torsion applies aforementioned pressure so that comber 1 to paper-feeding roller 2 pressurizations.Perhaps, arm 12 itself is exactly elastic body or comprises elastic component, as long as so just utilize the elasticity of arm 12 and the deadweight of comber 1 to apply aforementioned pressure so that the friction wheel 40 of comber 1 pressurizes to paper-feeding roller 2.
In paper distributing mechanism of the present invention, because the external diameter of friction wheel 40 be big than the external diameter of sleeve 10, sleeve 10 can't contact paper-feeding roller 2, has only friction wheel 40 to contact paper-feeding roller 2.Therefore, only there is the friction wheel 40 can wearing and tearing and need be replaced, do not need complicated step, only need friction wheel 40 unloaded from the two ends of axis body 20 and new friction wheel 40 loaded onto to get final product and change friction wheel 40.Using under the situation of O type ring as friction wheel, more need not use any dismantling devices, only need utilize the elasticity of O type ring can it be unloaded.In addition, because torsion limiting member 30 directly entangles axis body 20, therefore the external diameter of whole comber can be reduced effectively.
Below will explain how paper distributing mechanism of the present invention reaches the effect of separation with reference to figure 5.Paper-feeding roller 2 is rotated with friction wheel 40 rotations that drive comber 1, supposes that two pieces of paper are opened S1 and S2 enters between comber 1 and the paper-feeding roller 2 simultaneously.At this moment, paper-feeding roller 2 contacts with paper S1, and friction wheel 40 contacts with paper S2.Paper-feeding roller 2 utilizes the lasting paper S1 that drives of the friction force between paper-feeding roller 2 and the paper S1 to advance.Can or can not rotate as for friction wheel 40, depend on that paper S1 drives the size of the power of friction wheel 40 through paper S2.Torsion limiting member 30 is designed to overcome paper S1 especially and is driven the power of friction wheel 40 through paper S2, but can't overcome the power that paper-feeding roller 2 drives friction wheel 40.Therefore; Paper S2 fixed by friction wheel 40 or even through stored energy mechanism design (the for example elasticity of friction wheel 40 itself) paper S2 is back driven by friction wheel 40; Cause between paper S1 and the S2 and produce slide relative, avoid paper S2 to get in the paper-feeding channel, reach the effect of separation.
Fig. 9 is the lateral plan of expression according to the paper distributing mechanism of second embodiment of the invention.As shown in Figure 9; The comber 1 of present embodiment also comprises paper stopping component 13, and it can be the retaining paper washer, and has the first end 13A and second opposed end 13B; The first end 13A is fixed on the outside face 10A that is parallel to axis body 20 of sleeve 10; The second end 13B is then unfixing, but extends towards the direction of paper-feeding roller 2, and can contact or not contact with paper-feeding roller 2.The main effect of paper stopping component is before separation, earlier some paper S to be kept off, to increase the usefulness of paper distributing mechanism.That is to say that paper stopping component is used to stop that at least one paper S gets between comber 1 and the paper-feeding roller 2.
Figure 10 is the lateral plan of expression according to the paper distributing mechanism of third embodiment of the invention.Shown in figure 10, the comber 1 of present embodiment also comprises paper stopping component 13 ', and it has first end, 13 ' A and second opposed end 13 ' B, and first end, 13 ' A is fixed on the arm 12, and second end, 13 ' B is then unfixing.Paper stopping component is used for when multi-paper feed is arranged, stopping that at least one paper S gets between comber 1 and the paper-feeding roller 2.
Figure 11 is the lateral plan of expression according to the paper distributing mechanism of fourth embodiment of the invention.Shown in figure 11, the comber 1 of present embodiment also comprises paper stopping component 13 ', and it has first end, 13 ' A and second opposed end 13 ' B, and first end, 13 ' A is fixed on the main body 3, and second end, 13 ' B is then unfixing.Second end, 13 ' B extends towards the direction of paper-feeding roller 2, and can contact or not contact with paper-feeding roller 2.Likewise, paper stopping component 13 is used for when multi-paper feed is arranged, stopping that at least one paper S gets between comber 1 and the paper-feeding roller 2.
The specific embodiment that in the detailed description of embodiment preferably, is proposed is only in order to convenient explanation technology contents of the present invention; But not with narrow sense of the present invention be limited to the foregoing description; In the situation that does not exceed spirit of the present invention and above claim; The many variations example of being done all belongs to scope of the present invention.
