Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate making apparatus and a plate making printing apparatus having this plate making apparatus.

[0002]

2. Description of the Related Art A heat-sensitive digital plate-making type stencil printing device is known as a plate-making printing device. In this heat-sensitive digital plate-making stencil printer, for example, a very thin thermoplastic resin film having a thickness of 1 to 2 μm and a porous support (base)
As a heat-sensitive stencil master (hereinafter simply referred to as "master") constructed by laminating natural fibers such as Japanese paper, synthetic fibers, or a mixture of natural and synthetic fibers
Is provided with a plate-making device such as a thermal head, and the plate-making device is provided with a plate-making device that conveys and feeds the plate-made master so as to wind it around a porous cylindrical plate cylinder.

The current plate-making apparatus has been designed to be faster and to save space, and along with this, the master transport path has become complicated from a simple straight path. For example, referring to FIGS. 2 and 3 which will be described later, a specific example will be described. As shown in FIGS. 2 and 3, a bending box 32 including bending ducts 33a to 33c with three-stage switching is provided. In order to convey the master 16 that has been prepressed via the above, in addition to the two suction fans 34a and 34b having the same suction capacity on the inner side of the flexible box 32, suction fans similar to the suction fans 34a and 34b are further installed. It has been arranged in the central portion in the master width direction (three suction fans in total) to assist the conveyance of the master 16 that has been prepressed, and to perform the master conveyance. The flexible box 32 is provided below the master transport path XR in order to save space in the height direction, that is, in the vertical direction due to layout restrictions for downsizing the stencil printing apparatus and the plate making apparatus. .

Further, as the master transfer path becomes complicated, the transfer of the master 16 is becoming extremely difficult.
It is becoming very difficult to judge and recognize the position of the master 16 that has been prepressed in the bending box 32 and the remaining of the jammed master 16.

[0005]

However, the suction fan alone cannot overcome the rigidity of the masters themselves or the frictional resistance between the masters, and the masters that have been plate-prepared at the portion immediately before being conveyed to the inlet of the bending box. There was a master transport jam. Here, with reference to FIG. 10, the above-described trouble phenomenon will be described in a somewhat simplified manner. In FIGS. 10A to 10C, reference numeral 16 indicates a master. This master 16 is, for example, a thermoplastic resin film made of polyester (hereinafter sometimes referred to simply as "film").
And a natural fiber of Japanese paper as a base are laminated to form a laminated structure. Reference numeral 16a indicates a film surface on the film side, and reference numeral 16b indicates a Japanese paper fiber surface on the base side. Reference numeral 28 indicates a cutter unit as a cutting means for cutting the master 16.

The cutter unit 28 has a master transfer direction X.
The cutting means (4) shown in FIGS. 2 to 5 of Japanese Unexamined Patent Publication No. 2000-6510 is a known device for moving the master 16 in the width direction orthogonal to and cutting the master 16.
Is similar to. That is, the cutter unit 28
As shown in FIGS. 10A to 10C, is mainly composed of a frame 212 as a cutting means main body, a holder 213 as a cutter member, a rotation moving means 214 and the like.

In FIGS. 10 (a) to 10 (c), reference numeral 213a denotes an upper blade holder that rotatably supports a disc-shaped upper blade 216a, and reference numeral 213b denotes an upper blade 216.
The lower blade holder which rotatably supports the lower blade 216b having the same shape as a is shown. Reference numeral 213c is provided on the holder 213,
A connecting portion that integrally connects the holders 213a and 213b is shown, and is movably supported by the frame 212. The upper blade holder 213a includes an upper blade 216a and an upper roller 21 formed of a high friction resistance member integrally provided coaxially therewith.
7a are rotatably supported. Upper blade 216a
Is disposed at a position where a part of its blade surface overlaps the lower blade 216b, and the upper roller 217a makes its peripheral surface contact the upper surface 212a so as to sandwich the upper surface 212a with the lower roller 217b. The lower blade holder 213b is composed of a lower blade 216b at the downstream end in the master transport direction and a lower roller 21 composed of a high friction resistance member integrally provided coaxially therewith.
7b are rotatably supported. Lower roller 21
The peripheral surface of 7b is in contact with the inner surface of the upper surface 212a.

Reference numeral 218 indicates a bidirectional feed screw which constitutes the rotational movement means 214. The frame 212 is provided with a rotation moving means 214. Rotational movement means 214
Is mainly composed of a bidirectional feed screw 218 and a DC motor (not shown) as a motor. Reference numeral 221
Reference numeral 221a denotes a guide member main body fixed to a stationary member (not shown), and reference numeral 221b denotes a guide piece attached to the lower end of the guide member main body 221a. Guide piece 22
The base 1b is fixed to the guide member main body 221a at its base end and is made of an elastic body such as a metal thin plate or a resin thin plate.
6 is located above 6, and the free end of the holder 213 is located between the upper blade holder 213a and the upper surface 212a when the holder 213 moves. The upper blade holder 213
a, the guide piece 221b is attached to the upper blade holder 2 when moving.
An inclination for guiding between 13a and the upper surface 212a is formed at the front end in the moving direction.

With the above structure, when the holder 213 moves along the frame 212, the rollers 217a and 217b rotate in the opposite directions along with the movement, and the rollers 217a and 217b are provided integrally with each other. The blade 216a and the lower blade 216b rotate in opposite directions.

The cutter unit 28 as described above is similar to the reason for arranging the bending box 32 described with reference to FIG.
In particular, because of layout restrictions for downsizing the stencil printing apparatus and plate making apparatus, the stencil printing apparatus and the plate making apparatus are arranged to suppress the height and save space in the vertical direction. The so-called guillotine-type cutting means, which comprises a fixed blade fixed to the master transport path and a movable blade that can be raised and lowered with respect to the master blade, has a driving means such as a cam for moving the movable blade up and down in the vertical direction. It is not adopted due to the design layout constraint that it is required above and space cannot be saved by suppressing the height.

10 (a) to 10 (c), in a bending box (not shown), the plate-making master 16 forms a bending 16C which bulges downward due to the suction action of the suction fan. When a predetermined amount of the plate-made master 16 is stored in the bending box, the master plate can be fed, and the reversing roller pair 40 starts to rotate in the direction of the arrow in the drawing during the master plate feeding. The leading end of the master 16 is fed toward the spreader (not shown) of the plate cylinder, which is in the standby state at the plate feeding position. At this time, the rotation / conveyance of the pair of reversing rollers 40 causes frictional resistance between the Japanese paper fiber surfaces 16b of the master 16 in the vicinity of the entrance (opening) of the bending box or in the bending box so that the Japanese paper fiber surfaces 16b are rubbed against each other. The plate-made master 16 on the sending side, which is conveyed to the vicinity, is lifted and rises.

The swelling of the master 16 that has been prepressed is roughly classified into three, as shown in FIGS. 10 (a) to 10 (c), depending on the size thereof. FIG. 10A shows
The rising 16D indicates a large state. In this state, the upper blade 216a rises when the master is cut.
Since it passes under 6D, a cut error occurs. Figure 10
(B) has shown the state where the bulge 16D is inside.
In this state, 16D rises when the master is disconnected
When the height is about the same as the central portion of the upper blade 216a, the master 16 on which the plate-making is finished in the swelling 16D is crushed and locked (hereinafter, referred to as "cutter lock"). Figure 1
0 (c) indicates that the swelling 16D is small because the Washi paper fiber surfaces 16b of the master 16 do not contact each other and rub against each other, or the contact area and the contact time are extremely small. Belongs to the master transport state of.
In this state, problems such as cut mistakes and cutter lock do not occur.

In particular, in the flexible box 32 described with reference to FIG. 3, the plate-making master 16 is folded back into three stages and stored, so that the contact area between the Japanese paper fiber surfaces 16b of the plate-making master 16 is increased. Since it becomes larger, the degree of occurrence of cut mistakes, cutter lock, and the like increases. The above-mentioned cutting mistakes at the time of master cutting and cutter lock are one of the factors that cause the master conveyance jam. Such problems such as cut mistakes and cutter locks have a movable upper blade and a fixed lower blade, and the movable upper blade is a fixed lower blade, as disclosed in, for example, Japanese Patent Publication No. 7-84086. On the other hand, as the master 16 moves while rotating in the width direction, as disclosed in Japanese Utility Model Publication No. 3-40556, it has only a movable upper blade and this moves while rotating with respect to the master 16. It occurs even for things. It is speculated that the above-mentioned guillotine-type cutting means has very few occurrences of cut mistakes, cutter locks, etc., but the above-mentioned guillotine-type cutting means is not adopted for the above reason, and even if it is adopted, FIG. And when the master 16 that has been prepressed is cut in the state where the swelling 16D (large and medium) shown in FIG. 10B is generated, the leading end of the master 16 for the next prepress causes unevenness, and the cutting precision is poor. It is judged that it cannot be put to practical use, and it causes problems such as a paper ejection error described later or stains the impression cylinder, the press roller, and the like.

Problems such as cut mistakes and cutter lock have occurred when the thermoplastic resin film surface of the master is wound on the master roll, that is, when the film is wound in the film plane. In the case of a so-called film outside-winding master (a state in which the thermoplastic resin film surface of the master is wound around a master roll), the film surfaces stick to each other due to the influence of static electricity generation, and the above-mentioned swelling 16D occurs. (Large, Medium) may occur. On the other hand, the swelling 16D due to the Japanese paper fiber surfaces 16b of the master 16 occurs regardless of the environment.

In addition to the above-described master conveyance jam, the masters that have been prepressed are wound around the outer peripheral surface (plate cylinder) of the printing drum in a bent or overlapping state. It was also a cause of soiling the pressing means). For example, if an A3 size master of 1 plate is wound around the plate cylinder in a state of being folded in half, the mesh screen is exposed at the rear end of the plate cylinder. The printing paper sticks due to the force, and the trailing edge of the printing paper rolls up on the plate cylinder, resulting in a paper discharge jam. Further, in this case, when the A4 size printing paper is passed in the lateral direction, that is, the lateral printing is performed, the impression cylinder, the press roller and the like are contaminated with ink.

On the other hand, if the plate-made master remains in the bending duct of the bending box, it becomes an obstacle during the master conveyance for the next plate making, or the ability to suck the plate-making master into the bending box is reduced. As a result, a suction failure may occur, which causes a jam of the master transport. In addition, since the master after plate making is not conveyed normally, it has been a cause of cutter lock and eventually damage to the cutter unit.

Therefore, the present invention has been made in order to solve the above problem in view of the above-mentioned circumstances, and in a plate making apparatus or a plate making printing apparatus having a bending box (master storage means), a cut at the time of cutting the master. Occurrence of master conveyance jam due to mistakes or cutter lock, or impression cylinder or press roller etc. (pressing means) due to winding of masters that have been plate-making on the plate cylinder in a bent or overlapping state
First of all, it is possible to prevent stains on the paper and paper jams, to accurately convey the master, and to obtain stable master conveyance.
The purpose of.

A second object of the present invention is to reliably detect a master remaining in the bending box in a plate making apparatus or a plate making printing apparatus having a bending box, so that the occurrence of a master conveyance jam due to a cutter lock or the like can be prevented. The purpose is to prevent breakage of the cutter unit and obtain stable master transportability.

It has a function as a notification control means for controlling the display unit 95B and the jam occurrence display lamp 96.

Thirdly, the control unit 120 controls the plate making start signal from the plate making start key 91 and the plotter motor 24.
Based on the start signal of the
It has a function of operating the suction fans 34a and 34b and the blowing fan 35 when forming 6C. Fourth
In addition, the control device 120 has a function of operating the blowing fan 35 during plate feeding by the pair of reversing rollers 40 based on the plate making start signal from the plate making start key 91 and the start signal of the stepping motor 41.

Next, the operation of the stencil printing machine 1 will be described.
This operation example is based on the timing chart shown in FIG. 5 of Japanese Patent Laid-Open No. 2001-150786 (when the energy saving mode is not taken into consideration in the operation example 1), and the operation by the peculiar configuration of the first embodiment is folded. Although it is reflected, a part of the description of the operation described in the above publication is omitted in order to simplify the description. The plotter motor 24 described above,
In describing the operation of each control target drive means such as the stepping motor 41, the suction fans 34a and 34b, and the blowing fan 35, when various control target drive means are driven, including the embodiments described later, "ON" The time when driving is stopped is sometimes referred to as “off”. Further, after the ON / OFF operation by each control target drive means is described once, the operation description related to the ON / OFF operation by the control target drive means will be omitted.

The initial state of the stencil printing machine 1 is shown in FIG.
As shown in FIG. 1, in the plate making device 15, the master roll 1
The leading end of the master 16 fed from 6A is set to a plate feed standby position held by the nip portion of the reversing roller pair 40, and the plate cylinder 2 and the impression cylinder 9 are set to the home position. In the initial state of FIG. 1, first,
The user turns on the power switch. Before and after this, a plurality of originals 7 are placed on the original placing table 72 of the original reading device 70.
3 is placed and set, and when the printing paper S is insufficient or not on the paper feed tray 61, the printing paper S
Replenish and set as appropriate. The plate supply standby position of the plate making device 15 is not limited to the above position, but may be, for example, the cutter unit 2.
2, the upper surface 212a of the frame 212 in FIG. 8 is set to the left end in FIG. 2 to save the master 16.

Next, an operation for starting plate making / printing is performed. First, when the user presses the plate making start key 91 to turn it on, a plate making start signal is transmitted to the control device 120. As a result, a series of operations including discharging the plate, reading the image of the original, plate making, plate feeding, plate printing, discharging, and idling after the plate is performed. Here, when the stencil printing apparatus 1 is used for the last time or during continuous plate making, there may be a master conveyance jam in the bending box 32 or a residue of the master 16 that has been plate-made during the previous plate making. is there. In such a case, immediately after the user presses the plate making start key 91 to turn it on, the control device 120 causes the plate making start signal from the plate making start key 91 and at least one of the four remaining master detection sensors 36a to 36d. Based on the master presence signal from the sensor, the operation of the plotter motor 24 is stopped to prohibit the plate making operation, and
The operation of the pressure release motor (34) is stopped to bring the platen standby state in which the pressure release rotation position is occupied (the thermal head 22 is kept apart from the platen roller 23), thereby making the platen roller 23 and the tension roller Pair 2
The rotation of 6 and the static elimination roller 27 is stopped, and the plate making operation is stopped.

At the same time, the control device 120 controls the plate-making start signal from the plate-making start key 91 and at least one of the four remaining master detection sensors 36a to 36d.
Based on the master presence signal from the two sensors, the remaining of the plate-made master 16 is determined by the bending duct 3 of the bending box 32.
The guidance unit 95A, the auxiliary display unit 95B, and the jam occurrence display lamp 96 are controlled so as to notify and display that the information is within 3a to 33c. That is, the operation panel 9
The jam occurrence display lamp 96 of 0 lights up and blinks,
A message indicating that a conveyance jam has occurred in the master 16 and the master 16 that has been plate-making remains, and their occurrence locations and locations are properly displayed on the guidance section 95A and the auxiliary display section 95B of the liquid crystal display section 95, respectively.

The user performs the jam processing by appropriately observing the blinking display of the jam occurrence display lamp 96, the message display of the guidance section 95A, the display of the jam occurrence location of the auxiliary display section 95B, and the like. For example, the remaining master detection sensor 3
When the location where 6b and 36c are arranged is displayed as a jam occurrence location, the user opens a front door (not shown) provided on the front surface of the stencil printing apparatus 1 and is further provided at the bottom of the flexible box 32. The opened and closed door 31 is opened, and the jammed plate-finished master 16 remaining in the flexible ducts 33b and 33c may be taken out from below. As a result, it is possible to prevent a jam of the master conveyance jam at the time of the next plate making (here, at the time of plate making which will be described later), the cutter lock, the damage of the cutter unit 28, and the like, so that a stable master carrying property can be obtained.

The four remaining master detecting sensors 36a to 36d are used in the current plate making process, as described in paragraphs (0144) and (0155) of JP-A-10-202996, for example. By detecting the leading end position of the plate-making master 16 which is being conveyed, it can be used to detect a master conveyance jam or the like. That is, the remaining master detection sensors 36a to 36d are installed within the preset conveyance set time or the preset number of pulses to be supplied to the plotter motor 24 at the leading edge of the master 16 that is currently being conveyed. When the sheet does not pass through the spot, the operation of the plotter motor 24 is stopped to prohibit the plate making operation, and a message such as the occurrence of the conveyance jam of the master 16 and the spot where these are generated are displayed on the guidance section 95A and the auxiliary display section 95B, respectively. It can also be done.

The plate-making start signal generated by pressing the plate-making start key 91 triggers the subsequent operation flow. The manual operation by the user is until the plate-making start key 91 is pressed, and the subsequent operation up to the idle rotation after the plate making is automatically performed. Here, ink is supplied by the ink supply device 5 in the plate cylinder 2 to form an appropriate ink reservoir 8, and the elevating motor of the paper feeding device 40 is turned on so that a predetermined paper feeding pressure / separation pressure is obtained. Etc. are set.

First of all, the plate cylinder 2 having the used master 16 of the previous plate wound around the outer peripheral surface thereof and occupying the home position is turned on by the main motor being turned on.
The rotation starts in the clockwise direction indicated by the middle arrow, and the main motor is turned off in accordance with the plate ejection position to stop at the plate ejection position. Hereinafter, the on / off operation of the main motor will be omitted. During the plate discharge and plate feeding operations, the plate cylinder 2 rotates while being separated from the outer peripheral surface of the impression cylinder 9.
When the plate cylinder 2 stops at the plate ejection position, the clamper motor is turned on to open the clamper 4 at a predetermined angle, so that the clamper 4 is expanded. The locking state of the moving means by the locking means is released, and the plate discharge peeling roller 67 is released.
Occupies a peeling position where it comes into contact with the used master 16 on the plate cylinder 2, and at the same time, the plate discharge motor is turned on. As a result, the plate discharge peeling roller 67 is rotated and pressed against the outer peripheral surface of the plate cylinder 2 corresponding to the front end of the used master 16 held by the clamper 4, and the front end of the used master 16 is pressed. Is discharged by the plate discharge peeling roller 67.
Is scooped up from the outer peripheral surface and peeled off. Immediately after this,
The plate discharging / peeling roller 67 is returned to the original state shown in FIG.
It is returned to the separated position shown in FIG. 1 and is rotatably held together with the plate discharge roller 68. Immediately after the plate discharge peeling roller 67 is returned to the separated position, when the clamper motor is turned on to close the clamper 4, the clamper 4 is closed by the biasing force of the torsion coil spring and the magnetic force of the rubber magnet.
Hereinafter, on / off operations of the clamper motor and the plate discharge motor will be omitted. Plate cylinder 2 after clamper 4 is closed
When the is rotated in the clockwise direction, the substantial plate ejection operation starts. The used master 16 that has been peeled off is conveyed while being peeled from the outer peripheral surface of the plate cylinder 2 by the rotation / conveying operation while being held by the nip portion of the plate ejection peeling roller 67 and the plate ejection roller 68, and inside the plate ejection box 69. Will be discarded.

On the other hand, the plate making apparatus 1 immediately after the plate making start signal is generated.
In No. 5, when the pressure release motor (34) is turned on and rotated, the platen pressure is applied to the master 16 between the platen roller 23 and the thermal head 22, and the state of the application of the platen pressure is detected. The sensor (35) detects off. Since the platen pressure is released in the plate-making standby state, the platen roller 23 and the thermal head 22 are separated from each other, and the upper and lower rollers of the tension roller pair 26 are separated from each other.
The slack occurs in the master 16 from the master set roller 19 to the reversing roller pair 40. When the master 16 is directly mounted on the plate cylinder 2 for printing, winding wrinkles may occur, or the plate making start position may become unstable and the plate making start position may shift, so platen pressure is applied. Immediately after that, the master 16 is conveyed a little and the slack of the master 16 is removed by turning on only the stepping motor 41 for a predetermined time without driving the plotter motor 24. At this time, between the master set roller 19 and the master set guide plate 20, between the platen roller 23 and the thermal head 22, between the nip portions of the tension roller pair 26, the charge eliminating roller 27 and the upper surface 212a of the frame 212.
The master 16 between and is transported to the downstream side in the master transport direction X while sliding between each member while appropriately rotating each roller. After this, stepping motor 4 during plate feeding
Until the first driving, the motor 41 is controlled to be excited. As described above, since the stepping motor 41 is excited at a predetermined timing, the reversing roller pair 40 is free to rotate, and it is possible to prevent the master 16 that has performed the plate-making start alignment from being displaced due to vibration or the like.

Next, in parallel with the movement of the plate cylinder 2 to the plate ejection position and the plate ejection operation, the image reading operation and the plate making (writing) operation of the original document 73 are started by the document reading device 70 and the plate making device 15. The lowest document 73 of the plurality of documents 73 set on the document table 72 is automatically conveyed to a predetermined position on the contact glass 74, and the image of the document 73 is read by the document scanning optical system. The analog image signal photoelectrically converted by the image sensor 77 is input to the A / D converter. The document 73 from which the image has been read is discharged onto the document discharge tray 75. Above A / D
The analog image signal input to the conversion unit is converted into a digital image signal, and the digital image signal is transmitted to the plate making control unit via an image signal processing unit (not shown).

On the other hand, in parallel with the image reading operation of the document 73, the thermal head 2 by the plate making control section receives a digital image signal from an image signal processing section (not shown).
The plate making operation and the plate discharging operation automatically proceed in parallel while controlling the number 2. The heating element of the thermal head 22 is selectively heated according to the digital image signal, and the film portion of the master 16 pressed by the thermal head 22 against the platen roller 23 is selectively heated and melted to be punched. While the plotter motor 24 is turned on, the platen roller 23 and the tension roller pair 2 are turned on as shown in FIG.
6 and the static elimination roller 27 are respectively rotated in the directions of the arrows in the drawing, so that the master 1 which has been perforated
6 is transported to the downstream side of the master transport path XR without sticking due to static electricity or the like. On the other hand, the stepping motor 41 remains off, so that the reversing roller pair 40 remains stopped.

At the same time, as shown in FIG. 2, the blowing fan 35 and the suction fans 34a and 34b are both turned on and rotated. As a result, the blowing fan 35 is located near the upper portion of the opening 32a, that is, the frame 2
The air is blown from above, which is the direction in which the flexure 16C is formed in the plate-made master 16 between the left end of the upper surface 212a of 12 and the reversing roller pair 40, and the suction fans 34a, 34
The rotation of b causes the airflow to be folded back from the top to the left and right in the figure, so that the master 16 that has been prepressed is sagged from the opening 32a.
While being formed so that C becomes gradually larger, and while being switched, it is guided in the bending ducts 33a, 33b, 33c of the bending box 32 in a manner of being sequentially folded back while being guided by the plates 33a, 33b. In this way, the plate-made master 16 is stored in the bending ducts 33a, 33b, 33c of the bending box 32.

The description will be mixed up, but during the plate making operation, the plate cylinder 2
Rotates clockwise and stops at the plate feeding position. During this period, in the plate discharging device 66, the plate discharging peeling roller 67 and the plate discharging roller 6
The plate discharge operation by the operations of 8 and the like is continued, and the used master 16 corresponding to the rotation amount of the plate cylinder 2 is peeled off and discarded and discharged into the plate discharge box 69. During this period, the plotter motor 24 is driven on in the plate making device 15,
Deflection 16 on the master 16 that has been prepressed by the master storage means 30
The plate making operation while forming C continues.

On the other hand, during the plate making (writing) operation,
While the plate cylinder 2 is rotationally moving to the plate feeding position, the sheet feeding device 60
Then, by turning on the paper feed motor to rotate the paper feed roller 62 and the separation roller 63, and by the cooperative action of the separation roller 63 and the separation roller 63a, the topmost sheet of the paper feed tray 61 is The printing paper S is fed, and the leading end of the printing paper S is abutted against the portion of the registration roller pair 64 immediately before the nip portion. Thereafter, the paper feed motor is turned off and the rotations of the paper feed roller 62 and the separation roller 63 are stopped, whereby the leading edge of the print paper S is brought into contact with and held by the nip portion of the registration roller pair 64, and The rear end portion of S comes into contact with and is held by the paper feed roller 62 and the separation roller pair 63.

As soon as the plate cylinder 2 stops at the plate feeding position, the clamper 4 is ready for the plate feeding operation, that is, for the plate loading.
Is expanded and the plate cylinder 2 is in a plate supply standby state. During the plate supply standby state, the plate discharging operation by the plate discharging peeling roller 67 and the plate discharging roller 68 in the plate discharging device 66 is suspended. At this time, the stepping motor 41 is turned on (started) at a predetermined timing to rotate the reversing roller pair 40, so that the leading end of the plate-making master 16 is expanded while being guided by the plate feed guide plate 42. It is conveyed to the clamper 4. When the stepping motor 41 is turned on for a predetermined number of steps and it is determined that the leading end of the plate-making master 16 has reached the clamper 4, the stepping motor 41 is turned off and the operation of the reversing roller pair 40 is stopped, and at the same time, The clamper 4 is closed. As a result, the tip of the master 16 that has been plate-made is locked by the clamper 4.

At the time of printing, the stepping motor 41 and the plotter motor 24 are respectively controlled by a command from the control device 120 so that the master conveying speed v2 by the stepping motor 41 becomes higher than the master conveying speed v1 by the plotter motor 24. By changing the pulse frequency (pps) to be supplied, the master transport speed v2
The stepping motor 41 and the plotter motor 24 are controlled so that ≧ master conveyance speed v1.

As described above, during the plate feeding including the period when the stepping motor 41 is turned on and the reversing roller pair 40 is rotating, in other words, the plate-making master 16 is printed after the stepping motor 41 is turned on. During the plate feeding operation while moving through the nip portion of the reversing roller pair 40 to be wound around the cylinder 2, the blowing fan 35 blows air from above the master 16 that has already made the plate, including the opening 32a. Since the force due to the air blow acts so as not to contact and separate the Japanese paper fiber surfaces 16b of the master 16 on the sending side and the master 16 on the sending side, FIG. 10 (a) And the Japanese paper fiber surface 16b of the master 16 that has been prepressed as shown in FIG.
They do not come into contact with each other and rub against each other around the opening 32a from inside the bending box 32. Therefore, the frictional resistance causes the master 16 on the feed side, which is conveyed near the opening 32a of the bending box 32, to rise and rise. It is prevented from happening.

Next, a master winding operation for plate feeding is performed. By the plate cylinder 2 rotating in the clockwise direction and the stepping motor 41 being excited at the same time,
The rotation of the upper roller of the pair of reversing rollers 40 is stopped, and a load is applied to the master 16 that has been plate-formed on the outer peripheral surface of the plate cylinder 2 to prevent winding wrinkles. After the stepping motor 41 is excited, the upper roller of the reversing roller pair 40 is stopped (locked) by receiving the hold load due to the excitation of the stepping motor 41, and the lower roller of the reversing roller pair 40 is set to the plate cylinder 2 The master 2 which has been prepressed by the rotation of
Followed rotation. Due to the rotational force of the plate cylinder 2, the plate-made master 16 stored in the flexible box 32 is pulled out and wound around the outer peripheral surface of the plate cylinder 2 without causing wrinkles or the like. At this time, the peripheral speed v of the plate cylinder 2 is set to be sufficiently higher than the master conveyance speed v ′ by the platen roller 23 in the plate making device 15 (v> v ′).
The controller 120 controls the rotation speeds of the main motor and plotter motor 24.

On the other hand, at the same time when the plate feeding operation is performed,
In the plate discharge device 66, the plate discharge operation is restarted, and the used master 16 corresponding to the rotation amount of the plate cylinder 2 is separated and conveyed from the outer peripheral surface of the plate cylinder 2 by the operation of the plate discharge peeling roller 67 and the plate discharge roller 68. Then, it is discarded and discharged to the plate discharge box 69. On the other hand, the reading operation by the document reading device 70 and the writing operation by the plate making device 15 progress,
When the control device 120 determines that the master operation 16 for one plate has been completed by the number of steps of the plotter motor 24 after the reading operation is completed, the controller 12
By the command from 0, the plotter motor 24, the blowing fan 35, and the suction fans 34a and 34b are turned off. As a result, the rotations of the master set roller 19, the platen roller 23, the tension roller pair 26, and the static elimination roller 27 are stopped, and the plate making (writing) is performed.
The operation ends. At this time, the amount of flexure 16C of the plate-finished master 16 in the master storage means 30 is gradually decreased (even smaller than that shown in FIG. 10C, for example, so that there is no room for swelling 16D to occur. When the bending amount of the master 16 is minimum, the motor of the cutter unit 28 is turned on so that the cutter unit 28 moves along the frame 212 while rotating in the master width direction Y. Then, the rear end of the master 16 that has been plate-cut is cut. After cutting the rear end of the plate-making master 16, the cutter unit 28 returns to the original home position and the motor is turned off.
Therefore, a master conveyance jam due to a cutting error of the cutter unit 28 or a cutter lock will not occur.

On the other hand, in the printing device 14, the paper feeding operation is started in synchronization with the rotational movement operation in which the plate cylinder 2 occupies the home position. When the registration motor is turned on, the printing paper S is printed by the registration roller pair 64.
The paper clamper 12 is fed after being fed at a predetermined timing in synchronization with the rotation of the paper gripper 12
After the printing paper S is gripped, the paper gripper clamper 12 is closed, the impression cylinder 9 is rotated while the printing paper S is held on the outer peripheral surface of the impression cylinder 9, and the plate cylinder 2 and the impression cylinder 9 are rotated. The printing paper S is fed to the nip portion between and. In accordance with this timing, the outer peripheral surface of the impression cylinder 9 can be brought into contact with and separated from the outer peripheral surface of the plate cylinder 2. After the printing operation, the outer peripheral surface of the impression cylinder 9 is the plate cylinder 2.
Is separated from the outer peripheral surface of. The nip portion between the plate cylinder 2 and the impression cylinder 9 is pressed by the urging force of the elastic printing pressure spring (not shown) provided in the impression cylinder contacting / separating means, whereby the printing paper is printed. S is pressed by the master 16 that has been plate-formed and is wound around the outer peripheral surface of the plate cylinder 2. At the time of this pressing, the ink supplied to the inner peripheral surface of the plate cylinder 2 by the ink roller 6 bleeds through the perforated portion of the plate-finished master 16 on which the plate-making image has been formed, and this bleeding ink Is transferred to the surface of the printing paper S, and a printed image is formed.

The printed printing paper S on which the printing image is formed is peeled by riding on the paper ejection pawl 82 when the pressure drum 9 rotates and the paper gripper 12 opens before the paper ejection pawl 82. While being sucked by the suction fan 86, it is discharged onto the conveyor belt 85 located below. Conveyor belt 8
The printed printing paper S on 5 is conveyed by the rotation of the suction paper ejection outlet roller 84 while being sucked onto the conveyance belt 85 by the suction fan 86, and is ejected onto the paper ejection tray 81 to complete the so-called plate printing. To do. The printed matter discharged by this plate printing is not counted as a regular printed matter.

The printing operation and the paper discharge operation are performed as described above, and in the vicinity of the plate cylinder 2 occupying the plate feeding position, the winding of the master 16 for one plate, which has been completed for one plate, is completed on the plate cylinder 2. The plate feeding operation ends. Next, the printed printing paper S is ejected onto the paper ejection tray 81, and the trial printing (printing printing) is performed.
Ends. After this, the plate cylinder 2 rotates to the home position and stops at the home position.

After completion of the plate-making printing, the user appropriately views the discharged printed matter (printing paper S) to appropriately judge whether or not the normal printing operation may be performed, and confirms the image quality and confirms the image position. If the user presses the print start key 92 when the confirmation is appropriately performed and if these are OK, the same paper feed as described above is performed to feed and print the first printing paper S for normal printing. The operation, the printing operation, and the paper discharge operation are performed.

On the other hand, when the rotation operation of the registration roller pair 64 is stopped and the printing operation is completed, the plate making device 15
The guide transport plate 31 moves from the bending formation position and occupies the guide transport position. At the same time, when the plotter motor 24 is turned on, the platen roller 23, the tension roller pair 26 and the charge eliminating roller 27 are rotated, and
When the stepping motor 41 is turned on and the reversing roller pair 40 is rotated, the leading end portion of the master 16 of the next plate cut by the cutter unit 28 is guided by the guide transport plate 31 and the plate feed guide plate 42, and the master transport is performed. It is transported to the downstream side of the road XR. Then, when it is determined that the leading end of the master 16 of the next plate has occupied the plate making standby position corresponding to the plate making start position shown in FIG. When both the motor 24 and the stepping motor 41 are turned off, the platen roller 2
3, the rotation of the tension roller pair 26, the charge eliminating roller 27, and the reversing roller pair 40 are stopped, and the standby state is established. Further, the thermal head 22 includes a platen roller 23.
Away from. Also in the document reading device 70, the scanner motor and the like are turned on to move to the home position and then turned off.

(Second Embodiment) A second embodiment will be described with reference to FIGS. 1 and 6 to 9. In FIG.

The non-holding position is a position that does not interfere with the tip (free end) of the holding guide plate 51 when the upper blade holder 213a of the cutter unit 28 shown in FIG. 10 moves in the master width direction Y during master cutting. Is set.

The structure around the holding guide plate 51 and the holding member displacing means 52 will be described in detail below. As shown in FIGS. 6 to 8, the pressing guide plate 51 has a substantially flat plate shape in plan view and is formed to extend in the master width direction Y.
In the drawing, the right end portion of the pressing guide plate 51 is inclined obliquely to the right so as not to be caught when the leading end of the master 16 is conveyed. As shown in FIG. 7, arm portions 51a are integrally formed on the restraining guide plate 51 on both sides thereof. The holding guide plate 51 is made of, for example, a synthetic resin such as a polycarbonate resin (PC). Both edges of the holding guide plate 51 on the base end side are bent upward at right angles, and are supported by both ends on the front side and the back side of the shaft of the upper reversing roller 7 so as to be rotatable by a predetermined angle.

Next, the stencil printing machine 1 according to the second embodiment
The operation of A will be described focusing on the points different from that of the first embodiment. The operation of the stencil printing apparatus 1A is the same as that of the first embodiment.
Compared with that, only a part of the plate making and plate feeding operations in the plate making apparatus 15A are different, so the plate making and plate feeding operations will be described. The plate making device 15
In the initial state of A, the holding guide plate 51 is held at the non-holding position shown by the solid line in FIG.

First, when the user presses the plate making start key 91 to turn it on, a plate making start signal is transmitted to the control device 120A, so that the plate is ejected, the original image is read, the plate is made, the plate is supplied, the plate is printed, the sheet is ejected, and the plate is ejected. After attachment, a series of operations including idling is performed. Here, when the stencil printing apparatus 1A is used for the last time or during continuous plate making, when there is a master conveyance jam in the bending box 32 or there is a remaining master 16 after the plate making at the time of the previous plate making. In accordance with a command from the control device 120A, the same operation and operation as in the first embodiment are performed.

The first difference from the operation of the first embodiment is
This is an operation at the time of forming the flexure 16C on the master 16 that has been prepressed during platemaking. That is, when the flexure 16C is formed on the master 16 that has been prepressed, the three suction fans 34a, 34a, 3
By turning on and rotating both 4b and 34c, by the same suction action as in the conventional case, which is stronger than that of the first embodiment by the airflow of the mode of folding back from the top to the left in the figure,
The flexing ducts 33a, 33 of the flexing box 32 are formed while the plate-making master 16 is formed so as to hang down from the opening 32a so as to gradually increase the flexing 16C, and while being guided by the switching plates 33a, 33b.
b and 33c are conveyed in a manner of being sequentially folded back.

The second difference from the operation of the first embodiment is
This is an operation when the stepping motor 41 is turned on (started) at a predetermined timing and the reversing roller pair 40 is rotated when the plate cylinder 2 is in the plate supply standby state. That is, simultaneously with the rotation of the pair of reversing rollers 40, the control device 12
8 and 9, the DC solenoid 54 of the restraining member displacing means 52 is energized by the command from 0A, and D
The C solenoid 54 is driven on. DC solenoid 5
8 is turned on, the tip of the plunger 54a is sucked and moved by the stroke 57 from the position shown by the solid line to the position shown by the chain double-dashed line in FIG. 8, and the link 55 is moved and displaced downward. As a result, as shown in FIG. 8, the holding guide plate 51 held at the non-holding position shown by the solid line is oscillated and displaced downward as shown by the two-dot chain line arrow to occupy the holding position shown by the two-dot chain line.

When the holding guide plate 51 occupies the holding position,

By restraining 16D, the bulge 16D is restrained small so as to be extended in a substantially horizontal state as shown in FIGS. 6 to 8. Further, in the holding position, the holding guide plate 51 holds an appropriate space with respect to the upper surface 212a of the frame 212 so that the holding master plate 16 does not hinder the feeding of the master 16 into the bending box 32 and the feeding by the reversing roller pair 40. Therefore, the front end of the master 16 that has been plate-made is fed by the plate feed guide plate 4 by the master conveying force generated by the rotation of the pair of reversing rollers 40.
While being guided by 2, it is conveyed to the expanded clamper 4. As described above, during plate feeding, including the period when the stepping motor 41 is turned on and the reversing roller pair 40 is rotating, in other words, the plate-making master 16 is placed on the plate cylinder 2 after the stepping motor 41 is turned on.

Since the holding guide plate 51 is held at the holding position during the plate feeding operation (when 0 is rotated and driven), as shown in FIGS. 10 (a) and 10 (b). In addition, due to the frictional resistance when the Japanese paper fiber surfaces 16b of the plate-making master 16 on the feeding side and the plate-making master 16 on the sending side contact and rub against the opening 32a of the bending box 32, the opening 32a of the bending box 32 is formed. Master 16 that has been plate-finished on the sending side that is transported to the vicinity
Even if the “large” or “medium” swell 16D of the master 16 that has been plate-made due to being lifted up is generated, it is suppressed by the holding guide plate 51 that occupies the holding position.

The third difference from the operation of the first embodiment is
This is the operation when the control device 120A determines that the master 16 for which one plate has been plate-made has been plate-formed by the number of steps of the plotter motor 24 after the reading operation is completed. That is, at this time, the plotter motor 24, the suction fans 34a, 34b, and
34c is turned off. As a result, the rotations of the master set roller 19, the platen roller 23, the tension roller pair 26, and the charge eliminating roller 27 are stopped,
The plate making (writing) operation ends. At the same time, in accordance with a command from the control device 120A, in FIG. 8 and FIG. 9, the power supply to the DC solenoid 54 is turned off and the DC solenoid 54 is turned off.

When the DC solenoid 54 is turned off, the link 55 is moved and displaced by the urging force of the spring 56 as shown by the solid line in FIG. As a result, as shown in the figure, the holding guide plate 51 is oscillated and displaced upward as shown by the solid line arrow, and occupies the non-holding position. Thereafter, as in the first embodiment, when the amount of flexure of the master 16 becomes the minimum, the cutting by the cutter unit 28 is performed.
