Description
Technical field
The present invention relates to a kind of printer paper disengagement gear and method thereof.More particularly, the present invention relates to a kind of printer paper disengagement gear and the method that one pile of printer paper can be separated one by one.
Background technology
Usually, printer paper is to have utilized the device of friction coefficient or deflection (buckling) to come from separating the printer paper in a pile by use.Figure 1 shows that one utilizes the conventional printer paper disengagement gear of friction coefficient.Referring to Fig. 1, transfer roller 1 contacts with the top of one pile of printer paper S.Separate roller 2 be arranged at printer paper and pile up the friction lining 3 of S front portion and contact.Elastic element 4 is pushed friction lining 3 to separate roller 2.When transfer roller 1 rotation, many printer paper P are sent between separate roller 2 and the friction lining 3.At this moment, produce a coefficientoffriction 1 between many printer paper P and the separate roller 2, produce a coefficientoffriction 2 between friction lining 3 and many printer paper P, produce a coefficientoffriction 3 between many printer papers, pass each other is μ 1＞μ 2＞μ 3.Therefore, even many printer paper P are admitted between separate roller 2 and the friction lining 3, have only and separate from printer paper S in a pile with a printer paper P1 of separate roller 2 contact and by separate roller 2 and friction lining 3.Used a segment length after the time when disengagement gear shown in Figure 1, separate roller 2 and friction lining 3 have been subjected to the contamination of foreign matter such as paper powder and dust.When separate roller 2 and friction lining 3 were subjected to staiing, coefficientoffriction 1 and coefficientoffriction 2 descended, thereby can cause two pieces of paper or plurality of sheets of paper to be presented simultaneously.In addition, when many printer paper P are subjected to rubbing, can produce static between separate roller 2 and friction lining 3.Static can cause many printer paper P to adhere to each other tightly, has reduced the separating capacity of this device then.
Figure 2 shows that an example utilizes the conventional disengagement gear of deflection.Referring to Fig. 2, transfer roller 1 contacts with the top of one pile of printer paper S, and a block piece 5 of installing by pre-determined tilt angle A places the front portion of this pile printer paper.When transfer roller 1 rotated, many printer paper P generally can begin in rotational direction to move.Friction force between transfer roller 1 and many printer paper P is greater than the friction force between each printer paper.Therefore, when the leading edge of many printer paper P touches block piece 5, have only printer paper P1, promptly topmost and transfer roller 1 contacted that printer paper at one pile of printer paper S, in many printer paper P to front slide and be sent.Afterwards, have only the front end bending of printer paper P1 and curve C 1 occurs, as shown in Figure 2.When transfer roller 1 was rotated further, printer paper P1 bending spring increased, shown in curve C 2.After printer paper P1 moved forward under the drive that transfer roller 1 rotates, it is straight that curve C 2 momentarinesses become, and shown in C3, has only printer paper P1 separated and send like this.Below, the state that momentariness is become straight curve C 3 is referred to as " deflection ".
The leaning angle A of block piece 5 is configured to be suitable on the common printer paper of general-duty.When attempting the thick printer paper that separately rigidity is stronger with the leaning angle A that is suitable for common printer paper, because because the cause of leaning angle A can not produce C1, C2, the BENDING PROCESS of C3 is so the problem that printer paper can not transfer out can occur.In this case, phenomenon may appear transshipping in the drive motor (not shown herein) of driving transfer roller 1.In addition, the phenomenon that two pieces of paper or plurality of sheets of paper are presented simultaneously may occur, or the leading edge of printer paper is sustained damage because bending phenomenon do not occur.Under the situation of using thin printer paper, because the reason of leaning angle A can not be carried out the deflection process smoothly, and the folding choking phenomenon of paper appears thus.
Summary of the invention

The specific embodiment
More fully the embodiment of the invention is described referring now to accompanying drawing.
In the embodiment of the invention shown in Figure 3, the printer paper disengagement gear comprise be used to transmit print paper P, with the contacted transfer roller in top (that is conveying element) 10 of one pile of printer paper S.This device further comprises a plurality ofly to be piled up the S front end with printer paper and contacts, thereby impels the elastic fibre 20 of printer paper P deflection.Described a plurality of elastic fibre 20 is set to two-dimensional shapes, for example hairbrush shape as shown in Figure 4.This pile printer paper S and elastic fibre 20 can be each other with predetermined angle relative tilts.The printer paper disengagement gear further comprises an adjustment wall 30.Adjust wall 30 and be set to end than elastic fibre 20 slightly by the back, or we can say slightly indentation some.Adjust the end that wall 30 can be parallel to elastic fibre 20.Elastic fibre 20 for example can be made with metal, plastics or rubber-like fiber.Though not shown in Fig. 3 and Fig. 4, elastic fibre 20 and adjustment wall 30 can be installed on along a plurality of positions of printer paper P front end.
As shown in Figure 5, when the front end of printer paper P inserts between the elastic fibre 20, produced for the first time and separated.Printer paper P inserts with an angle with respect to elastic fibre 20 and is beneficial to isolate individual printer paper.At this moment, because the weight of printer paper P can make elastic fibre 20 crooked slightly.Adjust wall 30 and can prevent that the end of printer paper P from inserting among the elastic fibre 20 too far by block the front end of printer paper P as limiting device.In addition, the adjustment wall 30 that is parallel to the end of elastic fibre 20 can make every printer paper P insert between the elastic fibre 20 with the same degree of depth.
Introduce an example of the separation process that the printer paper disengagement gear of this exemplary embodiment carried out below.
As shown in Figure 6A, when transfer roller 10 rotated, the printer paper below the printer paper P1 of top began to move with printer paper P1 as printer paper P2 and P3.The front end of printer paper P1, P2 and P3 can touch an elastic fibre (or row's elastic fibre) 20-1.Friction coefficient between transfer roller 10 and the printer paper P1 is bigger than the friction coefficient between printer paper P1 and the printer paper P2.Therefore, after the front end of printer paper P1, P2 and P3 touches elastic fibre 20-1, between printer paper P1 and printer paper P2, produce slippage.As a result, only printer paper P1 is continued to transmit.Between printer paper P1 and printer paper P2 and printer paper P2 and printer paper P3, there is friction force.Therefore, the conveying capacity of transfer roller 10 has also passed on printer paper P2 and the P3.So that printer paper P2 and P3 produce slight moving.
During beginning, because the rigidity of printer paper, printer paper P1 does not produce bending.On the contrary, when printer paper was urged, elastic fibre 20-1 produced crooked.When the rigidity of the elastic force of elastic fibre 20-1 and printer paper P1 equated, elastic fibre 20-1 stopped to continue crooked, and the front end of printer paper P1 begins bending, forms the curve D 1 as shown in Fig. 6 B.When transfer roller 10 was rotated further, the radius of curve D 1 increased and becomes curve D 2, thereby produced deflection.At last, shown in Fig. 6 C, printer paper P1 crosses the top of elastic fibre 20-1 and is continued to transmit.When transmitted at the top that printer paper P1 crosses elastic fibre 20-1, the power that is acted on the elastic fibre 20-1 by printer paper P1 had disappeared, thereby elastic fibre 20-1 returned to its virgin state, promptly from carrying out the transition to solid line as the dotted line Fig. 6 C.The restoring force of elastic fibre 20-1 promotes printer paper P2 and P3 in the opposite direction along the sender with printer paper P1.Like this, printer paper P2 and P3 are stopped by elastic fibre 20-1, can not be transmitted; Only printer paper P1 is separated and be transmitted.
Except separating by deflection, thick printer paper can also separate by the following method.Referring to Fig. 7, transfer roller 10 puts on conveying capacity F on the printer paper P1 can be decomposed into elastic fibre 20-1 place on the contact point of elastic fibre 20-1 and printer paper P1 tangential component Ft and vertical component Fn.At this moment, if tangential component Ft is bigger with the product of vertical component than printer paper P1 that is produced by vertical component Fn and the coefficientoffriction between the elastic fibre 20-1 4, then printer paper P1 slips over the top of elastic fibre 20-1 and is transmitted shown in the dotted line among Fig. 7.When printer paper P1 was transmitted the top of elastic fibre 20-1, the power that printer paper P1 acts on the elastic fibre 20-1 had disappeared, and then elastic fibre 20-1 returns to its initial position.The restoring force of elastic fibre 20-1 is along promoting printer paper P2 and P3 in the opposite direction with printer paper P1 sender.Like this, printer paper P2 and P3 are stopped by elastic fibre 20-1, can not be transmitted; Only printer paper P1 is separated and be transmitted.
Shown in Fig. 8 A, every paper P1, P2 can contact with different elastic fibre (or elastic fibre row) 20-1,20-2,20-3 with P3.Because the friction coefficient between transfer roller 10 and the printer paper P1 is greater than the friction coefficient between printer paper P1 and the printer paper P2, so produce slippage between printer paper P1 and printer paper P2.As a result, printer paper P1 continues to be transmitted.The conveying capacity of transfer roller 10 has also had influence on printer paper P2 and the P3.Therefore, printer paper P2 and P3 can be transmitted slightly.
Shown in Fig. 8 B, because the rigidity of paper, printer paper P1 does not produce bending during beginning.On the contrary, under the promotion of printer paper P1, elastic fibre 20-1 has produced bending.Elastic fibre 20-2 and 20-3 also can produce slight bending when printer paper P2 and P3 are transmitted.Yet elastic fibre 20-1 is the most severely crooked.When the rigidity of the elastic force of elastic fibre 20-1 and printer paper P1 reached balance, elastic fibre 20-1 no longer continued bending, and the front end of printer paper P1 begins bending, formed the curve D 1 as shown in Fig. 8 B.When transfer roller 10 was rotated further, the radius of curve D 1 increased and becomes curve D 2, thereby produced deflection.At last, shown in Fig. 8 C, printer paper P1 crosses the top of elastic fibre 20-1 and continues to be transmitted.When printer paper P1 was transmitted the top of crossing elastic fibre 20-1, the power that is acted on the elastic fibre 20-1 by printer paper P1 had disappeared, thereby elastic fibre 20-1 returns to its virgin state.When elastic fibre 20-1 returned to its virgin state, printer paper P2 and P3 were promoted in the opposite direction along the sender with printer paper P1 slightly.Like this, printer paper P2 and P3 are stopped by elastic fibre 20-1, can not be transmitted; Only printer paper P1 is separated and be transmitted.
For reducing transfer roller 10 drive motor (not shown) overloads, when printing the common printer paper of intermediate gauge, the leaning angle that the leaning angle between the front end of printer paper P or leading edge and the elastic fibre 20 can be when printing thick printer paper.Perhaps, Zhe stops up and two or many printer papers are sent to simultaneously in order to prevent to roll over, and the leaning angle that separates thin printer paper can be less than the leaning angle of the common printer paper of separation intermediate gauge.In the printer paper disengagement gear of the embodiment of the invention, thereby elastic fibre 20 can be made a response and the front end adjusted automatically with printer paper P forms suitable leaning angle to the rigidity of printer paper P.
Referring to Fig. 9, when printer paper P is the common printer paper of intermediate gauge, elastic fibre 20 will be in the case of bending shown in label 20a, balance each other with the rigidity with printer paper.When printer paper P is when having the thick printer paper of strong rigidity, elastic fibre 20 will be further crooked shown in label 20b; When printer paper P is when having the thin printer paper P of less rigidity, elastic fibre 20 will be lessly crooked shown in 20c among the figure.Leaning angle between the front end of printer paper P and the elastic fibre 20 is different for three kinds of different-thickness printer papers.Leaning angle by at tangent line La, the Lb of the contact point place of printer paper P front end and elastic fibre 20 elastic fibre 20 or Lc and the angle that forms between perpendicular to line Ea, the Eb of printer paper P or Ec define.If leaning angle represents with Ba, Bb or Bc that respectively then they satisfy Bb＞Ba＞Bc.Because when elastic fibre 20 is adjusted with respect to the rigidity of printer paper P, its natural torsion to one appropriate tilt angle can be separated effectively so have a lot of printer papers of different rigidity, thereby prevents to damage the leading edge of paper.
Referring to Fig. 4, can make numerous elastic fibre 20 electrical ground.For example, the fibrous framework 40 that numerous elastic fibres 20 are installed can be made of conductive material, and this support can ground connection.Like this, in the process of separating printer paper P,, thereby reduce the adsorption that between printer paper, produces owing to static because any static that the friction between the paper accumulates on printer paper P can be released by ground connection.
As mentioned above, printer paper disengagement gear and the method with exemplary embodiment of the present can reach following effect.
According to an exemplary embodiment, natural torsion becomes suitable angle because elastic fibre is by adapting with the rigidity of printer paper, can successfully separate and can prevent to damage the printer paper leading edge so have the printer paper of different rigidity.
According to another exemplary embodiment, by a plurality of elastic fibres are installed, it is inclined that it is piled up with respect to printer paper, and the front end of printer paper or leading edge are inserted between the elastic fibre, have realized first separation process.Therefore, two or many possibilities of presenting simultaneously of appearance in the printer paper transport process have been reduced.
According to another exemplary embodiment, be provided with one than the elastic fibre end adjustment wall of indentation slightly, thereby the front end that prevents printer paper inserts in the elastic fibre too far.
According to another exemplary embodiment,, thereby avoid causing appearance two or many situations that printer paper is presented simultaneously in the printer paper transport process by static for elastic fibre is provided with electrical earth device.
Though reference example embodiment describes the present invention and describes, but obviously, to those skilled in the art, under the situation of spirit of the present invention that does not deviate from claims and defined and scope, can make multiple variation to its form and concrete structure.
The application requires to enjoy in the preceence of on December 29th, 2004 to the 10-2004-0115034 korean patent application of Korea S Department of Intellectual Property submission, and its whole disclosures are incorporated into this by reference.
