Description
Technical field
The present invention relates to print field, be specifically related to a kind of paper feed, device for image forming.
Background technology
On the printing presses such as chopping machine, duplicator or scanning machine, be equipped with and quires is separated one by one and the paper feed sent out from sheet feed stacker.
With reference to Fig. 1-2, paper feed has extraction roller 3, paper feed roller 2 and pickup roller 1.Wherein extract roller 3 and be positioned at quires 4 upper surface, paper feed roller 2 and pickup roller 1 are positioned at the front end of quires 4 along paper supply direction X, between paper feed roller 2 and pickup roller 1 diametrically and have the kneading portion A mediated by static friction, when paper feed roller 2 rotates, under the effect of static friction force, pickup roller 1 is driven to rotate.Between the front end of quires 4 and kneading portion A, there is certain distance.Paper 4a by extracting after roller 2 extracts, sends out along paper supply direction X through kneading portion A.
As Fig. 1, when extraction roller 3 extracts individual paper 4a, paper feed roller 2 and pickup roller 1 all rotate along paper supply direction X, are sent by paper 4a; As Fig. 2, when the paper that extraction roller 3 extracts is more than one, such as extract roller 3 and be extracted paper 4a and paper 4b simultaneously, pickup roller 1 can stop the paper 4b sent by the kneading portion A between paper feed roller 2 and pickup roller 1 more, avoids occurring resending in paper supply process.Resending here, namely overlappingly sends into, and refers to multiple hanging togothers and is together admitted to situation in machine.
Have the limiter of moment controlling pickup roller work in the pickup roller of prior art, the mode of limiter of moment has multiple.
The first is constant moment killer (prior art one), when multiple paper are involved in, due to the rotation of limiter of moment restriction pickup roller, will be subject to the barrier effect of pickup roller and not by kneading portion A by the paper sent more.This limiter of moment structure is relatively simple, and cost is low, but when paper feed is in high-speed operation state or multiple paper are involved in, treatment effect is poor.
The second is reverse drive moment killer (prior art two), this limiter of moment comprises a reversion drive system, limiter of moment is fixed on the axle drive shaft of reversion drive system, when multiple paper are involved in, reversion drive systems limiter of moment drives pickup roller reversion, by the paper sent along oppositely pushing back, as Fig. 2 more.This limiter of moment can process the situation that multiple paper are involved in well, but due to needs increase by reversion drive system, complex structure, cost are higher.
Notification number is that the Chinese patent (prior art three) of CN202175454U discloses a kind of paper feed, it improves the structure of separate roller (being equivalent to aforesaid pickup roller) on the basis of prior art one and two, the structure of separate roller as shown in Figure 3, every root separation roller shaft 103 is arranged with two separate rollers covered by roller rubber 101, as in Fig. 3, in the roller rubber 101 of one of them separate roller, outside separation roller shaft 103, be arranged with a torque limiter 105, also comprise single-revolution spring 106.The structure that wherein torque limiter 105, main spring 106 form is equivalent to aforesaid limiter of moment.
As Fig. 3, roller rubber 101 and paper feed roller mediate (in Fig. 3 not shown paper feed roller, the position relationship between paper feed roller and separate roller can refer to Fig. 1-2) by static friction force, and when transmission paper, the outside face of roller rubber 101 contacts with paper static friction.
Torque limiter 105 comprises coaxially sheathed inside casing 105a, housing 105b, wherein inside casing 105a is fixedly arranged on outside separation roller shaft 103, it is outer and can rotate relative to housing 105b that roller rubber 101 is located at housing 105b, static friction contact between inside casing 105a and housing 105b and can relative sliding, separation roller shaft 103 maintains static; It is outer and can rotate relative to separation roller shaft 103 that return spring 106 is sheathed on separation roller shaft 103, its return spring pin 106a near torque limiter 105 is arranged in the housing 105b of torque limiter 105, and the return spring pin 106b away from torque limiter 105 is arranged in the roller rubber 101 of another separate roller.During paper supply, return spring pin 106a reverses predetermined angular, in an initial condition as Fig. 4.
The principle of work of this limiter of moment is as follows, with reference to Fig. 3-4:
Paper feed starts, paper feed roller rotates, rotated along H direction by static friction force band action roller rubber 101, drive the return spring pin 106b of return spring 106 to rotate along H direction simultaneously, and restoring moment is put aside in return spring 106, when static friction force reaches certain value, housing 105b overcomes the static friction force between interior housing and rotates relative to separation roller shaft 103 relative to inside casing 105a slip, return spring 106.Be embodied in roller rubber 101 to continue along a direction to rotate.
Once the static friction force between paper feed roller and roller rubber 101 reduces, then drive return spring pin 106b rotates backward by the restoring moment put aside in return spring 106, and roller rubber 101 is rotated backward.
According to above-mentioned principle, when the paper not transmitting paper or transmission only has one, paper feed roller, static friction force between roller rubber 101 and paper are comparatively large, and make roller rubber 101 can continue rotation along paper supply direction, are sent out by paper; When the paper transmitted is more than one, because the static friction force between paper is far smaller than paper feed roller, static friction force between roller rubber 101 and paper, then return spring pin 106 rotates backward under the effect of restoring moment, band action roller rubber 101 rotates backward, thus is sent back along reverse push by the paper sent more.
There is a defect in the structure of prior art three, in the program, reverse predetermined angular be in an initial condition arranged in housing 105b although describe return spring pin 106a, return spring 106 is loaded and puts aside certain restoring moment.But because roller rubber 101 is free to rotate, so, when not having External Force Acting, this restoring moment can be ordered about return spring pin 106b and is with action roller rubber 101 to rotate and unloads return spring 106 until return spring 106 returns to unloaded state.If remain the restoring moment of original savings in return spring 106, then need to carry out certain restriction by external force to limiter of moment.This will increase design difficulty, improve manufacturing cost.
If do not have external force to carry out certain restriction to limiter of moment, then in maintenance return spring 106, the restoring moment of original savings will inevitably be unloaded due to the rotation of roller rubber 101, until the restoring moment of original savings is zero in return spring 106.That is, if there is no the restriction of external force, in this limiter of moment, stably can not put aside initial torque, cause the program can not thoroughly solve the problem resend.Be analyzed as follows:
Shown in Fig. 1-2, between quires front end and kneading portion A, there is certain distance, if this distance is enough large, after then paper supply starts, before paper enters kneading portion A, roller rubber 101 turns over certain angle (as Fig. 4), the return spring pin 106b of return spring 106 turns over certain angle relative to initial position (in Fig. 4 shown in dotted line), make to put aside enough large restoring moment in advance in return spring 106, the restoring moment now put aside at least can overcome the static friction force between paper, like this, if enter the paper of kneading portion A more than one, then reverse by this restoring moment driven roller rubber 101, and paper propelling movement is gone back,
But, if the distance of quires front end and kneading portion A is less, mean once paper supply, the paper be then extracted will soon enter into kneading portion A, and now, the restoring moment not putting aside moment of gyration or savings in limiter of moment is also not enough to the static friction force overcome between paper, that is, if the paper now extracted is multiple, then multiple paper all can enter into kneading portion A, and are finally admitted in machine.
As can be seen here, the paper feed in prior art three thoroughly can not solve the problem of multiple sheet feed.

Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
The embodiment of the present invention provides a kind of paper feed, with reference to Fig. 5, comprises the pickup roller 10 and paper feed roller 20 mutually mediated, and extraction roller 30 spaced with paper feed roller 20.Paper feed roller 20 and pickup roller 10 are arranged in be treated for the front end (Fig. 5 not shown quires, can with reference to Fig. 1-2) of quires along paper supply direction X, extracts roller 30 and is positioned at paper feed roller 20 along the rear side in paper supply direction and is positioned at the upper surface of quires.Pickup roller 10 has pickup roll shaft 11.
Shown in Fig. 5 composition graphs 6-7, the paper feed of the present embodiment also comprises limiter of moment 40.Limiter of moment 40 comprises sleeve 41 and main spring 42, sleeve 41 is relative vertically with pickup roll shaft 11, main spring 42 external diameter R2 is in a free state greater than the internal diameter R1 of sleeve 41, main spring 42 is sheathed in sleeve 41 (Fig. 7) after external diameter being diminished by torsion, main spring 42 is also fastened in sleeve 41 and between sleeve 41 tightly exists static friction force; Meanwhile, put aside certain restoring moment in main spring 42, now limiter of moment 40 is in initial condition.
In the present embodiment, sleeve 41 maintains static, and does not rotate with the rotation of pickup roller 10.The external diameter of pickup roll shaft 11 is less than the internal diameter of main spring 42, and pickup roll shaft 11 is arranged in main spring 42.Wherein, between the outer peripheral face of pickup roll shaft 11 and the inner peripheral surface of main spring 42, there is certain gap, ensure that pickup roll shaft 11 does not affect the torsional deflection of main spring 42.
In other embodiments, pickup roll shaft also can not be arranged in main spring, such as: main spring can be positioned at axial one end of pickup roll shaft.Now, then do not need to limit the relation between the internal diameter of main spring and pickup roll shaft external diameter, as long as to meet between sleeve with pickup roll shaft axially relative, the first end of main spring is fixed on pickup roll shaft, pickup roll shaft can drive the first end of main spring to twist to be out of shape.
With reference to Fig. 8-9, main spring 42 has axial first end 42a and the second end 42b, first end 42a are fixedly arranged on pickup roll shaft 11, and the second end 42b freely.Main spring 42 is from the second end 42b towards the direction of rotation when hand of spiral of first end 42a and paper feed roller 20 paper supply, namely identical with the rotation direction X of (when there is not multiple sheet feed), pickup roller 10 during normal paper supply, make when pickup roller 10 rotates, the first end 42a of main spring 42 can be driven to deform towards the direction of reduced radius, with reference to Fig. 9.
With reference to figure 8, the principle of work of limiter of moment 40 in paper feed in the present embodiment is as follows:
Paper feed starts, and paper feed roller 20 rotates along paper supply direction X, drives pickup roll shaft 11 to rotate along paper supply direction X by static friction force.Pickup roll shaft 11 drives the first end 42a of main spring 42 to rotate, and the first end 42a of main spring 42 deforms along the direction of reduced radius, to make in main spring the restoring moment of savings in 42 strengthen further.Certain static friction force is there is between second end 42b of main spring and sleeve 41.When the static friction force that pickup roller 10 is subject to reaches certain value, main spring 42 can overcome the static friction force between sleeve 41 and slide relative to sleeve 41, and being embodied in main spring 42 can continue to rotate along paper supply direction X.Now be in a state balanced between the restoring force of main spring 42 and static friction force.Once the static friction force that pickup roller 10 is subject to reduces, then the restoring moment put aside in main spring 42 will make first end 42a rotate backward, and drive pickup roller 10 to rotate backward.
According to above-mentioned principle, when the paper not transmitting paper or transmission only has one, paper feed roller 20, static friction force between pickup roller 10 and paper are enough large, pickup roller 10 can be made along paper supply direction can to continue rotation, sent out by paper; When the paper transmitted is more than one, because the static friction force between paper is far smaller than paper feed roller 20, static friction force between pickup roller 10 and paper, then the first end 42a of main spring 42 rotates backward under the effect of restoring moment, drive pickup roller 10 to rotate backward, thus the paper sent is sent back along reverse push more.
In the present embodiment, the main spring 42 of limiter of moment 40 is by reversing rear loading sleeve 41, make limiter of moment 40 just put aside certain restoring moment at initial condition, and remain this restoring moment, not unloaded by the restriction of sleeve 41.As long as limiter of moment 40 is greater than the static friction force between paper in the restoring moment that initial condition is put aside, even if multiple paper just arrive roller 12 in paper supply moment at the beginning, because the static friction force between paper is less, be not enough to allow pickup roller 10 overcome the restoring moment of above-mentioned initial savings and to rotate, so, pickup roller 10 is formed the paper sent more and stops, the paper sent can be stoped to enter into machine more.If there is recurring situation about resending, although resending of recurring can make main spring 42 drive pickup roller 10 continuous rotary, the restoring moment put aside in main spring 42 is reduced, restoring moment in main spring 42 also can not be less than this restoring moment initially put aside, therefore still can be formed the paper sent more and stop, prevent from resending.In the present embodiment, the structure of limiter of moment is very simple, low cost of manufacture.
With reference to Fig. 1-2, will extract roller and paper feed roller interval is arranged in prior art, be to strengthen the distance treated between confession quires and pickup roller, prevents the distance due to quires front end and pickup roller from the problem of multiple sheet feed too closely occurring.And in the present embodiment, from the above analysis, when adopting this limiter of moment 40, even if the distance of quires front end and pickup roller is very near, also can multiple sheet feed be avoided.So, in the variation of the paper feed of this enforcement, can save and extract the setting of roller, paper feed roller 20 can use as extracting roller simultaneously, that is, and can extract paper feed roller 20 roller 30 and unite two into one, as Figure 10.
With reference to shown in Figure 10, wherein in Figure 10, dotted portion is the extraction roller 30 in existing paper feed, in existing paper feed, extracts roller 30 and is positioned at quires upper surface, for extracting paper and to paper feed roller 20 paper feeding.When paper feed roller 20 and extraction roller 30 unite two into one time, then do not need to arrange and extract roller 30.Now, the diameter of paper feed roller 20 can be strengthened, paper feed roller 20 is positioned at the top of quires and has the first make contact 20a contacted with paper at first, and pickup roller 10 to be arranged in along paper supply direction X relative to the front of first make contact 20a, to mediate and form the second contact point 20b that pickup roller 20 finally contacts with paper with paper feed roller 20.Such set-up mode, when making normal paper feeding, paper a is extracted at first make contact 20a, is rotated be sent to the second contact point and be admitted in machine by the second contact point 20b by paper feed roller 20.Distance between first make contact 20a and the second contact point 20b then can make the limiter of moment in pickup roller 10 put aside certain pickup moment, to make when resending, pickup roller 10 can rotate along the direction contrary with paper feeding direction X, is pushed back by the paper b sent more.
Limiter of moment 40 has maximum pickup moment (Tr) and minimum pickup moment, with the effect preventing multiple sheet feed making limiter of moment 40 can reach desirable.Maximum pickup moment is that the Direction distortion of main spring 42 along reduced radius is to the moment put aside when can slide relative to sleeve 41, in main spring 42; Minimum pickup moment is main spring 42 moment of savings in main spring 42 when being installed in sleeve 41, under initial condition.The value (comprising maxim and minimum value) between minimum pickup moment and minimum pickup moment forms a pickup moment scope.
When limiter of moment 40 has different pickup moment scope, also different for preventing the effect of multiple sheet feed, concrete with reference to the form in Figure 11.
In Figure 11, choose thin paper, common paper and ground paper respectively and test, wherein common paper is about 80g/m
2paper, thin paper is about 50g/m
2paper, ground paper is about 300g/m
2paper.The scope of pickup moment Tr is used to be respectively for each paper: the limiter of moment of Tr<2.0cNm (1.0cNm=0.01Nm), 2.0cNm≤Tr<3.0cNm, 3.0cNm≤Tr<3.5cNm, 3.5cNm≤Tr<4.0cNm, 4.0cNm≤Tr≤5.5cNm, 5.5cNm<Tr≤6.5cNm, Tr>6.5cNm is tested, and by outcome record in the table.Wherein, the implication of each symbol is respectively:
Symbol " ◎ " representative does not resend, and can use;
The representative of symbol "○" does not resend substantially, can use;
Symbol " △ " represents that to resend frequency low, can use;
Symbol "×" represents that to resend frequency higher, is not suitable for using;
Symbol " E " represents pickup roller 10 and rotates hardly, wearing and tearing paper and paper feed roller 20, is not suitable for using.
As can be seen from the form of Figure 10, when pickup moment scope is between 3.0cNm ~ 6.5cNm, this is an operable scope, and now maximum pickup moment is 6.5cNm, and minimum pickup moment is 3.0cNm.
When pickup moment scope is at 3.5cNm ~ 6.5cNm, this is a good range of use, and now maximum pickup moment is 6.5cNm, and minimum pickup moment is 3.5cNm.
When pickup moment scope is at 4.0cNm ~ 5.5cNm, this is a best range of use, and now maximum pickup moment is 5.5cNm, and minimum pickup moment is 4.0cNm.
In the present embodiment, limiter of moment 40 is alternatively configured in pickup roll shaft 11, facilitates user to change.When limiter of moment reaches service life, then can be pulled down and be installed new limiter of moment, or also according to the different requirements to pickup moment under different occasion (difference of such as paper or environment), limiter of moment can be changed, to regulate pickup moment scope.
In addition, as shown in figure 12, the sleeve 41 in the present embodiment can be set to internal diameter and can regulate.Sleeve 41 is for having the annular of opening, and this opening can connect a buckle 41a, and buckle 41 can regulate the size of opening, and then the internal diameter of regulating sleeve 41.In actual applications, different use occasions needs the pickup moment scope possibility of limiter of moment different, uses the sleeve that internal diameter is adjustable, can adjust pickup moment scope more easily.
The embodiment of the present invention also provides a kind of device for image forming, comprising above-mentioned paper feed.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
