Abstract

PROBLEM TO BE SOLVED: To surely prevent the failure in folding of the continuous paper by contacting a point part of a swing guide feed-out part with a continuous paper surface when a swing guide is positioned at a left or right maximum swing position. SOLUTION: A swing guide 1 starts its swinging to right after it reaches a maximum swing position. It is important to keep the application of the optimum tension to the continuous paper 40 by the time when the swing guide 1 passes through a neutral position, and further reaches the maximum swing position at right. That is, a point of the continuous paper 40 is gripped by a claw belt, a paper tray 11 and a positioning stopper, and a state that the continuous paper 40 is contacted with a point 30a of a swing guide point member, is realized at least near the maximum swing position. Whereby the force is efficiently acted on the perforation when the perforation passes through the point 30a of the swing guide point member, the folded line is restored, and a mountain-like fold part is formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a printing apparatus,
The present invention relates to a continuous paper folding apparatus for stacking continuous paper after printing on a paper mounting table while sequentially folding the continuous paper in accordance with a fold of the previously formed continuous paper. The continuous paper referred to here is a printing paper which is provided with a perforation or the like which becomes a fold at every predetermined length and which is generally used for a printing machine used as an output device such as a computer.

[0002]

2. Description of the Related Art Generally, in a printing apparatus for forming an image such as a character or a symbol (for example, a bar code), a sheet sheet or a continuous sheet is used as an image recording medium. Of these, continuous paper is often formed with folds in advance at predetermined lengths, and the folds are alternately folded in the opposite direction, and are sequentially folded according to the folds after printing. ing. The folded continuous paper is normally stacked on a paper loading table on the paper supply side, one end of which is guided to a paper transport path in a printing apparatus, and is subjected to image transfer (and further fixing thereof if necessary). Are stacked again on the sheet placement table on the discharge side.

[0003]

As described above, the folds of the continuous paper are alternately bent in the opposite direction in advance, but the continuous paper is formed such that the folds of the continuous paper are extended along the transport path of the printing apparatus. Since the sheet is passed in a state and is pressurized or heated in an image transfer step or an image fixing step, the fold of the fold is easily lost, and normal folding according to the fold may be difficult. .

Particularly, in an electrophotographic printing machine in which an image is formed with colored particles called toner, which is transferred to continuous paper, and then fused and fixed, a nip portion between a pair of rollers is a serious problem. In the heat roll fixing method in which heat is passed and fixing is performed, heat and pressure can be applied simultaneously, so that the same effect as that of the so-called calendar processing is obtained, and the fold habit is easily lost. In addition, among the electrophotographic printing machines, a non-contact fixing method, for example, a flash lamp method,
In a method in which toner is melted by absorbing light energy, such as an infrared oven method, the light energy absorption efficiency differs between an image area where toner is present and a white background area where toner is not present. There is different and uneven paper stretching. If the paper expands or contracts in the direction of the fold (perforation), wrinkles crossing the fold are generated, and the paper has a three-dimensional structure, making it difficult to fold at the fold. As a result, so-called buckling may occur at a portion different from the perforation, which is a normal folding position, such as a boundary between the image region and the white background region, and the folding may not be performed normally.

In order to solve the above problem, there has been conventionally known an apparatus in which a continuous paper sheet is ejected from a processing apparatus so that a folding fold is formed again to make it easier to be folded (Japanese Patent Laid-Open No. Sho 57-57).
98462). As shown in FIG. 10, this device is provided with a swing mechanism 5 near the lower portion of the discharge port 51 of the printing apparatus.
The swinging mechanism 52 naturally swings according to a pre-formed folding habit of the continuous paper, so that the continuous paper 53 sent into the swinging mechanism 52 from the discharge port 51 is removed. The pendulum is moved in the direction of the fold to restore the fold of the fold that has been extended by heating, pressurizing or the like of the printing apparatus, thereby facilitating folding, and stacking regularly on the paper table 54.

However, the swing mechanism 52 as described above is used.
Even if the continuous paper 53 is pendulum-moved to restore the kinks, as described above, in order to heat or press the continuous paper 53 in the image transfer step or the image fixing step in the printing apparatus, If crossed wrinkles are generated, there is a possibility that a trouble occurs at the time of folding the continuous paper 53 without returning to the folding habit only by the pendulum movement by the swing mechanism 52.

The present inventors, when observing this phenomenon very closely, show that the swing mechanism 52 has no self-drive mechanism, so the swing angle is small, and the discharge port tip 55 of the swing mechanism 52 is Due to the open shape, the continuous paper is in the state shown by the dotted line in FIG. 10 when the perforation just passes the outlet end portion 55, and no force acts on the perforation. As a result, it was found that the folds could not be restored at the perforations.

Accordingly, an object of the present invention is to fold a continuous paper discharged from a printing apparatus without fail so that a continuous paper folding failure is less likely to occur, and a printing apparatus equipped with such a folding apparatus. Is to provide.

According to the present invention, there is provided a continuous paper folding apparatus which holds a printed continuous paper and sequentially folds the continuous paper in accordance with a fold of the previously formed continuous paper and stacks the continuous paper on a paper mounting table. And a swing guide that regulates both sides of the continuous paper and swings the continuous paper in the left-right direction according to the fold. When the swing guide is at the maximum swing position on either the left or the right, the continuous paper of the swing guide is provided. A continuous paper folding apparatus is provided, wherein a distal end of a swing guide discharge port located below a continuous paper path at a distal end of the discharge port contacts a continuous paper surface.

According to another aspect of the present invention, there is provided a continuous paper folding apparatus for holding continuous printed paper and successively folding the continuous paper in accordance with a fold of the previously formed continuous paper and stacking the continuous paper on a paper mounting table. There is provided a swing guide that regulates both sides of the continuous paper and swings the continuous paper in the left-right direction according to the fold, and the end of the continuous paper discharge port of the swing guide is narrowed to the paper side. Is provided.

Further, according to a preferred embodiment of the present invention, there is provided a continuous paper folding device, wherein the continuous paper discharge end of the swing guide is formed of a flexible member.

According to a preferred embodiment of the present invention, there is provided a printing apparatus including a continuous paper folding apparatus.

According to the above-described folding apparatus, the leading end of the swing guide comes into contact with the fold portion of the processed continuous paper sent out from the discharge port of the processing apparatus, and the force is applied correctly, thereby causing the back side of the fold of the continuous paper to move. The fold of the continuous paper that has been stretched is forcibly restored by pressing in the direction of the fold that the fold has in advance.

[0014]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows an embodiment of the folding device according to the present invention. In this embodiment, the continuous paper folding device includes a pair of conveying rollers 4 and 5 and a reflected light detection sensor 2 for detecting the leading end of the continuous paper.
In the vicinity of the lower part of the guide 6 having a zero, a swing guide 1 composed of a pair of left and right flat plates 1a and 1b is disposed. The pair of flat plates 1a and 1b extending in the vertical direction are arranged in parallel with an appropriate interval therebetween, and have a structure in which a flexible swinger tip member 3a, 3b is provided at a lower end thereof. I have. Swinger tip member upper end 3a,
3b is bent toward the continuous paper path, that is, inward. The swing guide 1 having such a configuration includes a support shaft 2a provided near the upper end of each flat plate,
2b, the left and right support shafts 2a and 2b are interlocked.
The parallel relationship between the flat plates 1a and 1b is always maintained during the swing. The swing guide 1 alternately swings in the left-right direction between a neutral position shown by a solid line in FIG. 1 and a maximum swing position at a left-right target position shown by a dotted line. Further, the swing angle and swing speed of the swing guide 1 can be adjusted, so that the swing guide 1 can appropriately cope with the difference in the length interval of the fold depending on the size of the continuous paper.

FIG. 2 shows the structure of the swing guide 1 in more detail. FIG. 2A shows the left and right flat plates 1a and 1b when the swing guide 1 is disassembled. Each has a flat plate corresponding to the lower leading end portion X and the root portion Y, and the root portion Y is located on the right side flat plate 1a of the paper path.
Is integrated with the left flat plate at the tip end Y. The flat plate 1b has an opposite structure. FIG. 2 (B) shows the assembled state. For example, the flat plate 1a is on the right side of the continuous paper path indicated by the dashed line, while the flat plate 1a is on the right side of the continuous paper path. It is on the left side of the paper path. Conversely, 1b is on the left side of the continuous paper at the root portion and on the right side of the continuous paper at the lower leading end. Further, tip members 3a and 3b obtained by bending a 0.35 mm-thick polyester film are attached to the tips of the flat plates 1a and 1b. The tip members 3a and 3b are bent toward the continuous paper path. That is, the left and right flat plates 1
Each of the leading end members 3a and 3b is configured so that the space at the leading end of the continuous paper discharge port formed by a and 1b is narrowed toward the paper as viewed from the plane plates 1a and 1b, respectively, from the non-leading portion. In this state, when the swing guide 1 is swung right and left around the support shafts 2a and 2b as respective rotation centers, FIG.
As shown in FIG. 2 (D), the trajectories of the leading ends 30a, 30b of the swing guide tip members 3a, 3b below the continuous paper greatly swing, so that the continuous paper can be swung more left and right, and the folding performance can be improved.

Returning to the description of FIG. Scratch belt 7
Are installed at regular intervals along the swing guide 1 (in a direction perpendicular to the plane of FIG. 1). The scratching belt 7 has a pair of pulleys 10a, 1
0b, a belt body 8 bridged therebetween, and claws 9 attached to the belt body 8 at predetermined intervals. The belt main body 8 and the claw portion 9 are made of an integrally molded elastic body, and reinforcing fibers are embedded in the belt main body 8 to prevent elongation. As shown in FIG. 1, the scratching belt 7 is normally used for the sheet table 1.
1, a positioning stopper 12a attached to the left and right sides of
12b, the belt body 8 is rotated in the direction of the arrow as shown in FIG. 5 and FIG. The portion 9 is hooked and acts to forcibly pull down the continuous paper 40. At this time, the claw portion 9 is adjusted to an appropriate softness so as not to excessively press the continuous paper. The scratching belt 7 and the positioning stoppers 12a and 12b are configured so as to be capable of being appropriately translated in the left-right direction according to the size of the continuous paper 3, as indicated by both solid lines and dotted lines in FIG. I have.

In FIG. 1, reference numeral 20 denotes a leading edge detection sensor that detects the leading edge of the continuous paper 40 and issues a drive start command signal to a swing drive mechanism (not shown) of the swing guide 1; An upper end detection sensor that issues a lowering command signal to a vertical drive mechanism (not shown) of the sheet mounting table 11 when detecting the upper end of the continuous paper 40 that has been received. Further, as described above, the swing timing of the swing guide 1 in the left-right direction is such that the leading edge detection sensor 20 of the continuous paper 40 at the start of the swing.
However, once the swinging is started, the swinging can be performed at a predetermined cycle according to, for example, the perforation interval of the continuous paper. The maximum swing position of the swing guide 1 is determined based on the sheet size specified on the processing device side.

Next, the operation of the folding device having the above-described configuration will be described with reference to FIGS. First, FIG.
As shown in (1), when the continuous paper 40 after printing is guided to the paper guide 6, the leading edge of the continuous paper 40 is detected by the leading edge detection sensor 20. The continuous paper 40 is further fed out and fed into a gap between the pair of flat plates 1a and 1b constituting the swing guide 1, and the swing guide 1 swings to the left (in FIG. 3) at a predetermined time from the detection of the leading end. In addition,
In this case, the swinging direction of the swing guide 1 and the folding direction of the fold of the continuous paper 40 to be discharged naturally coincide with each other. As means for matching, for example, the initial swing direction of the swing guide 1 is determined in advance as in the above embodiment, and when the continuous paper 40 is set in the printing apparatus, the continuous paper 4
Swing guide 1
Is set so as to be suitable for the swing direction of the continuous paper 40, or a direction in which the printing apparatus determines the fold direction of the first fold of the continuous paper 40.

The leading end of the continuous paper 40 sent downward from the lower end of the swing guide 1 comes into contact with the positioning stopper 12a and is positioned. At this time, the claw portion 9 repeatedly hits the leading end of the continuous paper downward, and is in a state of being held between the continuous paper 11 and the paper mounting table 11.

After reaching the maximum swing position, the swing guide 1 starts swinging to the right as shown in FIG. It is important that the continuous paper 40 be kept under a proper tension until the swing guide 1 passes the neutral position and further reaches the maximum swing position on the right side. That is, the leading end of the continuous paper 40 is gripped by the claw belt, the paper placing table 11, and the positioning stopper 12, and the state in which the continuous paper 40 is in contact with the leading end 30a of the swing guide distal end member 3a is at least maximally swung. This is realized near the moving position (Fig. 3
State shown in the figure). In this state, when the perforation passes through the distal end 30a of the swing guide distal end member 3a, a force is efficiently applied to the perforation using the distal end 30a of the swing guide distal end member 3a as a fulcrum, and as a result, a break occurs. The habit is restored and the mountain fold 23 is formed. Further, the leading end 30a of the swing guide tip member 3a and the continuous paper 40 at the maximum swing position opposite to the leading end of the continuous paper as shown in FIG.
If the linear distance D from the position 41 at which the leading end is gripped is 75% or more of the continuous paper crease interval (so-called paper top-to-bottom length), a stronger force acts on the perforation to improve the folding performance.

Then, as shown by a solid line in FIG. 5, the claw 9 rotating together with the belt main body 8 is engaged with the mountain fold 43 of the continuous paper 40 from above, and the continuous paper 40 is forcibly pushed down. . At the same time as described above, the mountain-folded portion 43 comes into contact with the positioning stopper 12b and is positioned.

In FIG. 6 showing the time when the swing guide 1 swings to the left again to reach the maximum swing position, the continuous paper is moved in the same manner as described in FIG. 4 (there is a difference between left and right). The folding habit of the left fold of 40 is restored. In addition,
FIG. 7 shows an operation state in which the left mountain fold 43 of the continuous paper 40 is positioned and placed by using the claw 9 of the belt 7, and the movement is different between left and right. Only this is the same as that described with reference to FIG. 5, and a detailed description thereof will be omitted.

After passing through FIGS. 6 and 7, the operation returns to the operation state shown in FIG. 4, and the operations shown in FIGS. 4 and 7 are repeated thereafter. Then, the continuous paper 40 is placed on the paper placing table 11.
Are stacked by a predetermined amount, and the upper end detection sensor 13 described above is stacked.
Detects the upper end of the continuous paper 40, the paper placing table 11 is lowered by a predetermined amount based on the detection signal.

FIG. 8 shows an embodiment of the shape of the tip of the swing guide of the present invention other than the embodiment described above. For comparison,
FIG. 8 (A) shows the tip of the conventional swing guide, but the tip expands in a trumpet shape compared to the continuous paper path interval up to that point. That is, the shape is such that the space at the end of the continuous paper discharge port is widened. With this configuration, when the swing guide is at the maximum swinging position on the left and right, there are two contact points with the continuous paper and the leading end does not come into contact with the paper. Did not return well. FIG. 8B shows the tip of another embodiment of the present invention, which is integrated with a sheet metal, and can be realized at a low price by being integrated with the sheet metal. FIG. 8 (C) shows a sheet metal swing guide in which the tip is straightened and a triangular acrylic square member is stuck to the tip. This shape is preferable because the linearity of the tip of the swing guide (in the direction perpendicular to the paper surface of FIG. 8) can be correctly maintained. FIG. 8 (D)
Is a polyester film bonded to the tip of the straight swing guide by extending it further. If the tip is in contact with the paper when the swing guide is at the maximum swing position, the flexibility of the film Thereby, an appropriate force can be applied to the perforation. FIG.
(E) is obtained by bending a polyester film inward at the tip of the sheet metal swing guide and bonding it.
The cross-sectional shape is changed between the printing surface and the back surface of the continuous paper. In other words, the leading edge on the side that contacts the printing surface has an arc shape near the leading edge so as not to damage the toner image on the continuous paper, and can also be used on special continuous paper such as tack paper with unevenness on the printing surface. Has applicable benefits.

Although the embodiment of the present invention has been described as above, it is only an example, and if it is based on the idea of the present invention, any object that can be designed by a person skilled in the art is included in the present invention. Included in the range.

FIG. 9 is a schematic view showing an entire electrophotographic printer provided with a continuous paper folding apparatus according to the present invention, and includes a photosensitive drum 101 as an image carrier.
The photosensitive drum 101 has a photosensitive material thin film 102 having photoconductivity formed on the surface of an aluminum drum as a base. Organic materials such as OPC (OPC)
rganic Photo Conductor), amorphous silicon,
Various materials such as selenium are applicable. The photosensitive drum 101 is rotatable at a constant speed in a direction indicated by an arrow in FIG. 9 by a drive system (not shown).

Immediately above the photosensitive drum 101, a primary charger 103 is disposed near the photosensitive material thin film 102. When the photosensitive material thin film 102 of the photosensitive drum 101 passes directly below the primary charger 103, the surface of the photosensitive material thin film 102 has the same polarity as the charged polarity of the toner particles (positive in the above toner example). In the same manner. In order to more uniformly charge the surface of the photosensitive material thin film 102, the primary charger 103 has a configuration in which a grid controlled at a constant voltage, specifically, a metal mesh is arranged between the corona wire and the photosensitive material thin film 102. The so-called scorotron type charger described above is preferable. Corotrons without grids can often be used without problems.

In the vicinity of the primary charger 103, an exposing device 104 and a developing device 105 are arranged in order in the rotation direction of the photosensitive drum 101. Exposure device 104
Includes a light emitting diode array that can independently emit light,
These light emitting diodes can emit a light beam toward the photosensitive drum 101. In addition to the light emitting diode, a method of scanning a laser beam such as a semiconductor laser with a polygon mirror or a method using a liquid crystal shutter may be used.

When the light beam is applied to the photosensitive material thin film 102 of the photosensitive drum 101, an electrostatic latent image is formed on the photosensitive material thin film 102. Thereafter, the electrostatic latent image is developed with toner by the developing device 105, so that a visualized toner image is obtained.

Immediately below the photosensitive drum 101, a transfer charger 106 facing the primary charger 103 with the photosensitive drum 101 interposed therebetween is arranged. The transfer charger 106 has the same configuration as the primary charger 103 and has a polarity opposite to the charging polarity of the toner particles.
02 can be transferred onto the continuous paper S. The transfer charger 106 may be of the above-described scorotron type. However, since it is prioritized to apply the electric charge to the back surface of the continuous paper S more efficiently than the uniformity, a so-called corotron type charger including a corona wire and a shield case is used. preferable.

In order to transfer the toner image onto the continuous paper S, it is necessary to supply the continuous paper S to the photosensitive drum 101. Therefore, the electrophotographic printer of the present invention employs a transport device for the continuous paper S. It has. This continuous paper S is perforated at a predetermined interval in the longitudinal direction and folded.
The fan-hold paper can be cut off. Therefore, sprocket holes are formed on both sides of the fan-hold paper at predetermined intervals.

The transport device has a pair of tractor units 113 disposed upstream of the photosensitive drum 101 when viewed in the direction in which the continuous paper S is supplied to the photosensitive drum 101. These tractor units 113 are positioned on both side edges of the continuous paper S, and have a large number of sprockets that can be engaged with sprocket holes of the continuous paper S. Here, the continuous paper S is transported by the pair of tractor units 113 such that the feed speed of the continuous paper S and the peripheral speed of the photosensitive drum substantially match.

The drawing unit 11 is located downstream of the photosensitive drum 101 in the supply direction of the continuous paper S.
4 are arranged. This drawer unit 114
A driven roll 241 disposed near the photosensitive drum 101
And the photosensitive drum 101 when viewed in the supply direction of the continuous recording paper S.
And a transport belt 240 wound around the drive roll 242 and the driven roll 241. Conveyor belt 2
A large number of small holes (not shown) are provided on the entire surface of the transport belt 240, and the paper is transported while suctioning the paper onto the transport belt 240 by a suction device (not shown) disposed on the back side of the transport belt 240. Go. Note that, around the photosensitive drum 101, a separation charger 107 for applying an alternating voltage to remove the sheet from the photosensitive drum 101 after transfer to remove and separate the charged sheet, and to transfer the sheet to the photosensitive drum 101. Separating claws 108 for preventing winding are provided. Further, a bias voltage having a polarity opposite to that of the toner particles is applied to the drawer unit 114, and the continuous paper S
The toner particles transferred thereon are prevented from detaching from the continuous paper S. This has the effect of not contaminating the transparent glass in the lamp housing opening, especially when the fixing device is of the flash flash type. The power source of the bias voltage can be shared with a bias power source applied to a cleaning device brush roll or a collecting roll described later.

Next, there is a cleaning device 110 for the photosensitive drum 101. This cleaning device 110
Are positioned downstream of the transfer charger 106 and upstream of the primary charger 103 when viewed from the rotation direction of the photosensitive drum 101.

In the vicinity of the surface of the photosensitive material thin film 102 of the photosensitive drum 101, a static elimination lamp 111 is disposed. The static elimination lamp 111 is provided after the photosensitive material thin film 102 has undergone the cleaning process by the cleaning device 110 described above. This is for removing the charge on the surface of the photosensitive material thin film 102.

On the other hand, as viewed in the transport direction of the continuous paper S, the fixing device 11
The fixing device 112 is for fixing the toner image to the continuous paper S while the continuous paper S passes under the fixing device 112. As the fixing device, any known method such as pressure, heat roll, and flash light can be used. However, in the case of the continuous paper S, the contact type fixing method may cause the recording paper to meander and cause paper jam. Therefore, a non-contact flash is preferred. In addition, non-contact type is a tack paper that can be pasted to other types compared to contact type,
Another advantage is that it can handle a wide range of paper such as thick paper. A xenon flash lamp is generally used as a fixing device for flash flash, but it is possible to further improve the fixing property of the toner to the recording paper by combining the xenon flash lamp with a halogen lamp which is always lit. A scuff roller 150 that transports the continuous paper S is provided downstream of the fixing device 112. By setting a slight speed difference between the tractor unit 113 and the scuff roller 150, that is, the linear speed of the scuff roller 150 to be faster than the linear speed of the tractor unit 113, tension is applied to the continuous paper S during this time. The printing position for the perforation is kept good.

The continuous paper folding apparatus described above was incorporated downstream of the scuff roller 150.

As described above, since the tension is applied to the continuous paper S from the transfer charger 106 to the fixing device 112, heat is applied only to the toner image area by the flash light. In particular, the fold of the continuous paper S is easily lost, and the continuous paper folding apparatus of the present invention is very effective.

[0039]

As described above, according to the continuous paper folding apparatus according to the present invention, the leading end of the swing guide acts on the perforated line of the printed continuous paper. The forcible habit of the fold of the continuous paper that has been extended in the image fixing process is forcibly restored, and there is an effect that the poor folding of the continuous paper can be reliably avoided.
