Paper feeder shown in the figure comprises first feeding-in roll, 101, the second feeding-in rolls 102, feeding-in roll supporting mass 2.First and second feeding-in roll 102,101 is made of the described feeding-in roll of Fig. 1 to Fig. 3 respectively.Feeding-in roll is made of with supporting mass the described feeding-in roll of Fig. 4 to Fig. 6 with supporting mass 2.
First and second feeding-in roll 101,102, each of the ora terminalis of its first and second supporting slice 12,13 closely are embedded in each of first to fourth groove 21～24, make up with supporting mass 2 with feeding-in roll.
In more detail, in first feeding-in roll 101, the ora terminalis of first supporting slice 12, closely embedding is combined in first groove 21, the ora terminalis of second supporting slice 13, closely embedding is combined in second groove 22.In addition, in second feeding-in roll 102, the ora terminalis of first supporting slice 12, closely embedding is combined in the 3rd groove 23, the ora terminalis of second supporting slice 13, closely embedding is combined in the 4th groove 24.
Here, preferably, set the internal diameter size D21 (with reference to Fig. 4) of first to fourth groove 21～24 less than maximum ga(u)ge diameter dimension D12, the D13 (with reference to Fig. 2) of first and second supporting slice 12,13.That is,, will become the internal diameter size D21 of first to fourth groove 21～24 of former, set maximum ga(u)ge diameter dimension D12,13 for less than first and second supporting slices 12,13 that become formpiston as both preferred matching relationships.
In addition, the interval D 22 (with reference to Fig. 4) between the first to fourth adjacent groove 21～24 in feeding-in roll, determines accordingly with the interval D 14 (with reference to Fig. 2) of first and second supporting slice 12,13 of the adjacency of subtend.Interval D 22 between first to fourth groove 21～24 of adjacency, preferably, in feeding-in roll 1, set for the interval D 14 of first and second supporting slice 12,13 of subtend adjacency about equally.Interval D 22 with first and second groove 21,22 shown in the figure equates to be prerequisite mutually with the interval D 22 of the 3rd and the 4th groove 23,24, but also can be consistent with the feeding-in roll that cooperates, and sets in the mode with different distances.
And then the greatest diametrical dimension D23 of first to fourth groove 21～24 (with reference to Fig. 6) decides by the contrast with through hole 15 maximum inner diameter dimension D 15 (with reference to Fig. 2) separately.Preferably, greatest diametrical dimension D23 is set greater than each maximum inner diameter dimension D 15 of through hole 15.
Feeding-in roll includes slit 26 with supporting mass 2.In paper feeder, use between the supporting mass 2 at feeding-in roll 1 and feeding-in roll, form very wide cavity 16.Slit 26 is from the inside and the external communications of cavity 16.
According to said structure, because the ora terminalis and first to fourth groove 21～24 of first and second supporting slice 12,13, its cross section is circular-arc, so, when each and first to fourth groove 21～24 with the ora terminalis of first and second supporting slice 12,13 closely assembled, between formed the contact surface of enlarged areas.
Simultaneously, preferably, the internal diameter size D21 of first to fourth groove 21～24 is set at maximum ga(u)ge diameter dimension D12, the D13 that is equal to or less than first and second supporting slice 12,13.Because first and second supporting slice 12,13 utilizes the rubber-like member to constitute, so, in a single day when being coupled on first to fourth groove 21～24, by the elasticity that feeding-in roll had, the ora terminalis of first and second supporting slice 12,13 flexibly is adjacent to compressed state with respect to the inside contact surface of first to fourth groove 21～24.Thereby feeding-in roll combines with supporting mass 2 well with feeding-in roll, is preventing that feeding-in roll from the axial offset of rotation, can stop its slip to hand of rotation.
In addition, preferably, the greatest diametrical dimension D23 of first to fourth groove 21～24 is set for the maximum inner diameter dimension D 15 of the through hole separately 15 that is equal to or less than first and second feeding-in roll 101,102.Thereby when both made up, each of first and second feeding-in roll 101,102 by its elasticity, in first to fourth groove 21～24, was crimped onto the radial direction of paper bowl with supporting mass 2.Thereby each of first and second feeding-in roll 101,102 combines with supporting mass 2 well with feeding-in roll, is preventing that feeding-in roll from the axial offset of rotation, can stop its slip to hand of rotation.
As mentioned above, feeding-in roll 1 utilizes its elasticity, is stably mounted at feeding-in roll with on the supporting mass 2.Thereby, just can be assembled into paper feeder at an easy rate without adhesive agent, screw etc. are fixing.And because feeding-in roll 1, and feeding-in roll do not have complicated integrated structure with supporting mass 2, so manufacturing easily.
Through hole 25 is arranged on feeding-in roll with on the axle center of supporting mass 2.Thereby, when using it for paper feeder, the S. A. that can drive at inner orientation etc.
Comprise slit 26 by feeding-in roll with supporting mass 2, can change cavity 16 in-to-in air, the shape of cavity 16 is changed from slit 26.Thereby, can guarantee very wide area of contact to paper, corresponding with diversified paper thickness variation, can obtain suitable crimp force and friction force.That is, can carry out paper feeding reliably.
In addition, owing to can change the in-to-in air of the cavity 16 of feeding-in roll 1 from slit 26, so cavity 16 is not a fully enclosed.Thereby, no matter be when contacting with paper, perhaps during noncontact, can both suitably keep being applied to air pressure on each of first and second feeding-in roll 101,102, can use the deterioration of the feeding-in roll that causes to be suppressed to bottom line owing to long-time from cavity 16.
4. make use-case
Figure 10 is that expression is omitted amplification profile according to the part of the running condition of paper feeder of the present invention.Figure 10 is to be example with paper feeder shown in Figure 7, the diagram that its part is amplified.
Paper feeder shown in Figure 10 comprises first feeding-in roll 101 and feeding-in roll supporting mass 2.And then, in Figure 10, with the paper 3 of the state of mounting on bench board 4 as the paper feeding object.These are the example through simplifying for convenience of explanation only, but because in the art, they are known structure divisions, so omit its details.
With reference to Figure 10, the paper feeding paper has S. A. a, is combined to along on the actuating device (not shown) of arrow R direction rotation.
D51 represents the maxim of the inner space distance of cavity 16.Because the part at space length D51 at paper contact surface 11, does not apply any thrust on first and second supporting slice 12,13, so the elasticity that is had by first feeding-in roll 101 forms stable shape.
Relative therewith, D52 represents the inner space minimum value and value of cavity 16.In the part of space length D52, on first feeding-in roll 101, paper contact part 11 contacts with paper 3, and applies the friction that is caused by rotation.Thereby, paper contact part 11, first and second supporting slice 12,13 is subjected to producing distortion by the thrust of paper 3 and bench board 4, is positioned at cavity 16 in-to-in air and is compressed, and is released to the outside by slit 26.Because cavity 16 in-to-in air are released to the outside, first feeding-in roll 101, the air pressure of its cavity 16 reduces and then along with the elasticity of first feeding-in roll 101 continues distortion, becomes bigger with respect to the area of contact of the paper contact part 11 of paper 3.
As mentioned above, because first feeding-in roll 101 is to constitute with the rubber-like member,, thereby increase with the area of contact of paper 3 so paper contact part 11 subsides dearly.Thereby can carry out paper feeding reliably.
In addition, the area that contacts with paper 3 increases, and paper contact part 11 reduces with the friction force of the unit area of the contact surface of paper 3.Therefore, the wearing and tearing of first feeding-in roll 101 reduce.Thereby,, can prevent that paper feeding is bad even long-time the use can not make friction force reduce because of the wearing and tearing of first feeding-in roll 101 yet.
And then, owing to paper contact part 11 subsides dearly, so, can relax of the minimizing of first feeding-in roll 101 from the friction force of paper 3 acceptance.Therefore, even, can prevent that also paper feeding is bad along with the elasticity of time first feeding-in roll 101 worsens.
First feeding-in roll 101, as mentioned above, because paper contact part 11 subsides dearly, with the area of contact increase of paper 3, paper contact part 11 reduces with the friction force of the unit area at the contact surface place of paper 3, so, can not peel off owing to friction force makes paper 3.Therefore, can not produce the paper powder can be by the paper powder with ambient contamination yet.
Because first feeding-in roll 101 is made of the rubber-like member, so, subside accordingly with the thickness of paper 3.Therefore, can irrespectively carry out paper feeding with paper thickness.
On the other hand, continue first feeding-in roll 101 of rotation, when the contact surface that breaks away from paper 3, on first feeding-in roll 101, apply restoring force by its elasticity along the hand of rotation shown in the arrow R.When first feeding-in roll 101 returns to the shape with space length D51, from slit 26 aspirated airs, so be easy to restore to the original state.Thereby, always with the state contact of the best, can carry out paper feeding reliably with respect to paper 3.
The effect of above-mentioned paper feeding paper and effect, the situation when being not limited to use first feeding-in roll 101.Because Fig. 1 is to feeding-in roll shown in Figure 3, and, Fig. 7 is to first and second feeding-in roll 101,102 shown in Figure 9, have identical effect and effect with first feeding-in roll 101 shown in Figure 10, so, they being combined to feeding-in roll when being used for paper feeder on supporting mass 2, can obtain same effect and effect.
Above, with reference to preferred embodiment content of the present invention has been carried out specific description, but according to basic fundamental thought of the present invention and enlightenment, those skilled in the art understand certainly, can adopt various form of distortion.
