And a moving optical system for scanning a light beam along a central axis in a circumferential direction and an axial direction.

[0002]

2. Description of the Related Art In recent years, a cylindrical inner surface scanning device has been required in the plate making industry, which requires a large amount of image drawing work on a photosensitive material because a moving optical system can easily increase a scanning speed in a circumferential direction. I have. Further, in the plate making industry, since it is necessary to perform image drawing work on a large amount of photosensitive material, there is also a demand for automatic loading of the photosensitive material into the inside of the cylindrical inner drum body. In order to meet these requirements, there is a cylindrical inner surface scanning device shown in FIGS.

FIGS. 28 to 30 are simplified diagrams showing the configuration of a conventional cylindrical inner surface scanning device. The cylindrical inner surface scanning device shown in FIG. 28 includes a transport device (not shown) that transports the photosensitive material 101 from one axial end to the other axial end of the cylindrical inner drum main body 100. The cylindrical inner surface scanning device shown in FIG. 29 includes transport rollers 103 and 104 on both upper side walls of a cylindrical inner drum main body 102, respectively.
A photosensitive material having a long circumferential length (a so-called roll-shaped photosensitive material) 105 is conveyed between the reference numerals 3 and 104. The cylindrical inner surface scanning device shown in FIG.
, And the photosensitive material 108 is conveyed in such a manner as to be pushed by the roller 107.

However, FIG.
In the cylindrical inner surface scanning device described above, spaces in which the transport device can move must be provided on both sides in the axial direction of the cylindrical inner surface drum body 100. Therefore, there is a first problem that the inner surface scanning device of the cylinder becomes large.

In the cylindrical inner surface scanning apparatus shown in FIGS. 29 and 30, when a photosensitive material having high bending rigidity such as an aluminum base is used, one side in the circumferential direction of the photosensitive material contacts the inner surface,
Since the movement in the circumferential direction is hindered, the feeding force by the roller is lost. When a light-sensitive material having low bending rigidity such as a plastic film base is used, one side in the circumferential direction of the light-sensitive material abuts on the inner surface, and the light-sensitive material buckles. Therefore, the cylindrical inner surface scanning apparatus shown in FIGS. 29 and 30 has a second problem that the photosensitive material cannot be fed reliably.

Accordingly, the inventor of the present application has invented a cylindrical inner surface scanning device that solves the first and second problems. This invention is disclosed in the patent application of Japanese Patent Application No. 6-63342. This invention has not been disclosed at the time of filing the present application.

The rotary arm unit 111B includes a rotary arm 1 rotatable about a central axis of the inner surface of the cylindrical inner drum body 110.
11B1, a plurality of L-shaped excavators 111B11 and rollers 111B1 attached to the rotating arm 111B1
2 is provided. A plurality of shovels 111 </ b> B <b> 11 and rollers 11 are attached to the photosensitive material sent from the transport roller unit 111 </ b> A into the cylindrical inner drum body 110.
The photosensitive material is drawn into the drum body by rotating the rotary arm 111B1 in the circumferential direction by sandwiching the photosensitive material between the drum and the drum 1B12.

However, in the cylindrical inner surface scanning apparatus shown in FIG. 31, when the photosensitive material is sandwiched between the shovel 111B11 and the roller 111B12, one side of the photosensitive material in the circumferential direction is the shovel 1B.
There is a third problem that the photosensitive material is damaged due to hitting 11B11.

Therefore, the present invention prevents an increase in size,
It is an object of the present invention to provide a cylindrical inner surface scanning device that can safely and reliably feed a drum into a cylindrical inner drum body.

Next, the operation will be described with reference to the flowchart shown in FIG. FIG. 14 is a flowchart of processing performed by the operator and the CPU 292 for the cylindrical inner surface scanning device. First, the operator determines in step S
In step 1, an unexposed photosensitive material is set. Details of step S1 will be described below. First, the operator opens the housing 4 and moves the supply cassette 3 from the photosensitive material storage unit 3.
Then, in the dark room, the lock handle 322 is unlocked and the door 310 is opened, and a plurality of unexposed photosensitive materials 1 are stored in the supply cassette 31 as necessary. At this time, the operator stores the photosensitive material 1 in the supply cassette 31 so that the base surface of the photosensitive material 1 faces the opening / closing door 310 side. This is because the exposed surface of the photosensitive material 1 is aligned with the central axis 221.
Draw the image by turning it to the side.
This is to prevent the exposed surface from being damaged at the time of conveyance by bringing the base surface into contact with the inner surface 200. When the photosensitive material 1 is stored, the left side of the photosensitive material 1 is placed in the supply cassette 31.
To the left edge of This is because the left side of the photosensitive material 1 is slightly protruded from the inner surface 220 to enable the sub-positioning by the punching device 27 and the formation of the punch holes.
After the stock is completed, the operator closes the opening / closing door 310, locks the lock handle 322, and sets the supply cassette 3
1 into the photosensitive material storage unit 3 and lock handle 32
2 is unlocked.

Next, in step S2, the operator operates the operation unit 41 to set the photosensitive material data. Details of step S2 will be described below. The operator operates the operation unit 41 to call up a SELECT screen (see FIG. 15) used by the user on the monitor 41A. On the Local SELECT screen, the file number, the file name, and the next selectable screen NEX
T PAGE and PLATE SET are displayed. The operator, for example, file number 2 and PLAT

And a punch number indicating a file number in which is stored. The operator may, for example, enter 1000 mm in the circumferential direction of the photosensitive material 1 stored in the supply cassette 31 in the column of the photosensitive material, 800 mm in the axial direction, and 0.24 mm in the column of the thickness of the photosensitive material.

The MENT, the pitch interval between the punches, and the size of the photosensitive material to be applied are displayed.

The operator once creates punch data files corresponding to the pin pitches of various printing presses on the PUNCCH DATA screen and registers them in the RAM 294.
It is only necessary to input the number of the punch data file in the Punch data field on the PLATE SET screen. Also, once a file is created in accordance with the size of the light-sensitive material, the thickness of the light-sensitive material, the foot size, and the pin pitch that are normally used on the PLATE SET screen and registered in the RAM 294, the operator can use the file number screen on the PLATE SELECT screen. You can start drawing a sensitive material just by inputting. When such an operation is completed, the operator presses the start button of the operation key 41B.

If a specific maintenance number is input at the time of setting, the LORDING PAR shown in FIG.
The AMETER SET screen is called. This LOR
The calling of the DING PARAMETER SET screen is performed at the time of assembling adjustment of the punch units 27Ea to 27Ee of the punching device 27 at the time of assembling the output unit 2 and at the time of assembling adjustment due to replacement of the punch units 27Ea to 27Ee after shipment.

The operator performing the maintenance mounts the punch units 27Ea to 27Ee on the punching device 27, displaces the origin M33-0 of the photosensitive material sub-positioning motor M33 in the axial direction X, and sets the punch units 27Ea to 27E.

5 is measured. Such a displacement is caused by the punch unit 2
In addition to measuring the mounting positions of 7Ea to 27Ee, the measurement is performed by measuring the positions of the punch holes formed in the photosensitive material 1.
The operator performing maintenance is LORDING
The PARAMETER SET screen is called, and the measured deviations in the axial direction X and the circumferential direction Y are input.
Register to 4. Note that the CPU 292 considers the displacement registered in the RAM 294 and takes the photosensitive material sub-positioning motor M into consideration.
33, by driving the puncher main positioning motor M100 to rotate, the punch units 27Ea to 27Ee
Is moved to a predetermined piercing position. When the registration is completed, the PUNCHDATA SET screen is called (see FIG. 19).

As a result, the operator performing the maintenance can move in the circumferential direction Y.
Can be confirmed to be completed. In addition,
Similarly to the PUNCH DATASET screen, the offset after the origin deviation in the axial direction X and the deviation of the punch unit may be displayed.

When the start button is pressed, the CPU 29
Reference numeral 2 denotes a photosensitive material loading mode (step S3) for transporting the photosensitive material 1 from the supply cassette 31 to a predetermined position on the inner surface 220 of the cylindrical inner drum body 22 according to a program stored in the ROM, and mounting on the inner surface 220 Exposure mode for exposing the selected photosensitive material 1 (step S4)
And an unloading mode (step S5) for transporting the photosensitive material 1 mounted on the inner surface 220 from the cylindrical inner drum main body 22 to the storage cassette 32. Steps S3 and S5 will be described later.

When step S5 is completed, the operator takes out the exposed photosensitive material 1 in step S6. That is, the operator first opens the housing 4, takes out the storage cassette 32 from the photosensitive material storage unit 3, opens the open / close door 310 with the lock handle 332 in the unlocked state in a dark room, and opens the exposed photosensitive material from the storage cassette 32. Take 1 out. Next, the empty storage cassette 32 is returned to the photosensitive material storage unit 3. The exposed photosensitive material 1 is sent to a printing process after passing through a developing process.

Next, the details of step S3 will be described.
FIG. 20 is a flowchart showing details of step S3. FIG. 21 shows steps S35 to S3 in FIG.
8 and the punching device 2
7 is a diagram illustrating an operation of FIG. In the photosensitive material loading mode, the CPU 292 first checks whether the supply cassette door opening / closing clutch motor M67 and the clutch 313 are engaged with each other by the supply cassette opening / closing clutch origin detection optical sensors SQ67a and SQ67b. Is rotated to open the door 310 of the supply cassette 31 (step S3).
1). The CPU 292 determines that the open / close door 310 is open by detecting the supply cassette door open / close detection optical sensor SQ6.
7, the supply light sensitive material size detection optical sensor SQ62a,
In SQ62b, the size of the photosensitive material 1 is checked, and it is determined whether or not the checked size of the photosensitive material 1 substantially matches the size of the photosensitive material set in the operation unit 41. If not, CP
U292 displays an error on the monitor 41A of the operation unit 41.

If they match, the process proceeds to step S32,
The CPU 292 sets the path change transport unit 25 to the loading position by rotating the transport path switching motor M51 forward. That is, the path change transport unit 25 is lowered to match the photosensitive material transport path of the pad transport unit 33.

Next, the CPU 292 causes the pad transport unit 33 to suck and transport the photosensitive material (step S33).
That is, the CPU 292 drives the suction cup moving motor M52 of the pad transfer unit 33 in the reverse direction to rotate the suction cup 335.
a, 335b, 335c from the initial position to the supply cassette 3
Move to the first photosensitive material 1. When the light-sensitive-material-adsorption-side detection optical sensor SQ52b detects the suction cups 335a, 335b, and 335c, the CPU 292 stops the reverse rotation drive of the suction cup moving motor M52 of the pad transport unit 33. As a result, the suction cups 335a, 335b, 335c contact the base surface of the photosensitive material 1. Next, the CPU 292 operates the vacuum pump VP70a, and detects the vacuum state by the vacuum pump VP70a using the vacuum switch P70. Also,
The CPU 292 controls the first timer T set in the RAM 294
Activate 1

If the vacuum switch P70 has not been turned on, the CPU 292 determines whether the elapsed time T1 of the first timer T1 has exceeded the suction time TP1 stored in the RAM 294 in advance. The suction time TP1 is a time required for the vacuum pump VP70a to operate normally and to suck the photosensitive material 1. Therefore, if T1> TP1, the suction cup 335
It is considered that a, 335b, and 335c did not reliably adsorb the photosensitive material 1 and were in a malfunction state. Therefore, the CPU 292 determines that the suction operation of the photosensitive material 1 is an error, and displays an error on the monitor 41A.

When the vacuum switch P70 is turned on within the suction time TP, the CPU 292 turns on the attraction solenoid valves V77a to V77c corresponding to the size of the photosensitive material. Thereby, the suction cups 335a, 335b, 335c are adsorbed on the photosensitive material 1.
Next, the suction cup moving motor M52 is driven to rotate forward to take out the photosensitive material 1 from the supply cassette 31 and carry it to the path change carrying unit 25 side. Thereby, the photosensitive material 1 is conveyed toward the path change conveyance unit 25 while being bent in an arc shape.

Further, the CPU 292 includes a suction cup moving motor M
52 is set in the RAM 294 at the same time when the
The timer T2 is operated, and the elapsed time T2 of the second timer T2
Is longer than the transport time TP2 stored in the RAM 294 in advance. The transport time TP2 is a time required for the photosensitive material suction / adsorption side detection optical sensor SQ52b to detect the leading end of the photosensitive material 1 in the transport direction when the pad transport unit 33 operates normally. Therefore, T2> TP
In the case of 2, it is highly probable that a transport error has occurred in the pad transport unit 33. In this case, the CPU 292
Determines that a transport error has occurred in the photosensitive material 1 and displays an error on the monitor 41A. When the photosensitive material suction / adsorption side detection optical sensor SQ52b detects the leading end of the photosensitive material 1 in the transport direction within T2 <TP2, the CPU 292 stops the forward rotation drive of the suction cup moving motor M52, and the electromagnetic valves V77a to V77.
Turn off c.

Next, the CPU 292 causes the path change transport unit 25 to transport the photosensitive material 1 (step S3).
4). That is, when the CPU 292 detects the leading end of the photosensitive material 1 in the transport direction by the path load side detection optical sensor SQ51a, the CPU 292 drives the transport motor M50 to rotate forward. At this time,
The tip of the photosensitive material 1 in the transport direction is the path change transport unit 2
5 between the drive rollers 251a0 and 251b0. Thus, the photosensitive material 1 is continuously transported from the pad transport unit 33 to the path change transport unit 25 side.
The CPU 292 activates the third timer T3 set in the RAM 294 simultaneously with the forward rotation driving of the transport motor M50,
It is determined whether the elapsed time T3 of the third timer T3 has exceeded the transport time TP3 stored in the RAM 294 in advance. The transfer time TP3 is determined by the path change transfer unit 25.
Detecting material passing detection optical sensor SQ50
Is the time required from when the leading end of the photosensitive material 1 in the transport direction is detected to when the photosensitive material passage detection optical sensor SQ32 detects the leading end of the photosensitive material 1 in the transport direction. Therefore, when T3> TP3, there is a high probability that a transport error has occurred in the path change transport unit 25. In this case, the CPU 292
Determines that a transport error has occurred in the photosensitive material 1 and displays an error on the monitor 41A.

When T3 <TP3, the CPU 292
Continues the rotation drive of the transport motor M50. As a result, the photosensitive material 1 is transported toward the in-drum transport unit 26 while being bent in an arc shape.

Next, the CPU 292 causes the in-drum transport unit 26 to draw the photosensitive material 1 into the drum (step S35). FIG. 22 is a flowchart showing details of step S35. First, when the photosensitive material passage detection optical sensor SQ32 detects the leading end of the photosensitive material 1 in the transport direction, the CPU 292 drives the photosensitive material introduction motor M32 to rotate in the forward direction, thereby causing the photosensitive material 1 to be driven by the guiding / discharging roller 26A to form the cylindrical inner drum main body. 22 (step S351). Next, the CPU 292 drives the rotary arm motor M30 of the rotary arm unit 26B to rotate in the reverse direction, thereby rotating the rotary arm 26B5 to the suction position on the guide / discharge roller 26A side (Step S352). Then, CPU2
Reference numeral 92 drives the photosensitive material pulling-in motor M31 in the forward direction to turn on the in-drum suction / conveyance electromagnetic valve V78. This allows
The suction cup 26B57 contacts the photosensitive surface of the photosensitive material 1 and is attracted to the photosensitive material 1 (step S353, see FIG. 21A). Next, the CPU 292 drives the photosensitive material drawing motor M31 to rotate in the reverse direction, returns the suction cup 26B57 to the origin position, and drives the rotary arm motor M30 to rotate in the forward direction. As a result, the leading end of the photosensitive material 1 in the transport direction rises, and the photosensitive material 1 is completely drawn into the cylindrical inner drum body 22 (step S354, see FIG. 21B).

Next, the CPU 292 controls the punch motor M
, 101, M102,...
The idle driving of 7Ea to 27Ee is performed (step S365,
S366).

As a result, the rear end of the photosensitive material 1 in the transport direction is lifted, and the photosensitive material 1 is pulled back toward the rotary arm unit 26B (see FIG. 21D). Next, the CPU 292 determines whether or not the main-scanning-direction photosensitive material positioning optical sensor SQ34 has detected the rear end of the photosensitive material 1 in the transport direction (step S374). When the main-scanning-direction photosensitive material positioning optical sensor SQ34 detects the rear end of the photosensitive material 1 in the transport direction (see FIG. 21E), the CPU 292 rotates the photosensitive material draw-in motor M31 to cause the squeegee roller 26B58 to rotate.

B58 is lowered. This position is
225a6 is on the area M1. Thus, the photosensitive material is fixed to the inner surface 220 in the region M1. Then, CPU
292 releases the suction of the suction cup 26B57 by turning off the suction and conveyance electromagnetic valve V78 in the drum (step S376) (see FIG. 8C). Next, the CPU 29
2 returns the rotary arm 26B5 to the origin position by rotating the rotary arm motor M30 forward while squeezing the photosensitive material 1 with the squeegee roller 26B58 (step S377). As a result, the photosensitive material 1 is

5a6 and the vacuum groove 229 communicating therewith have a negative pressure.
At this time, the photosensitive material 1 is squeezed around the area M1 by the squeegee roller 26B58. For this reason, the photosensitive material 1 near the region M1 is adsorbed and fixed to the inner surface 220. Next, the CPU 292 turns on the in-drum suction / conveyance electromagnetic valve V78 (step S382). As a result, the vacuum pressure in the vacuum holes 225b1 to 225b6 in the region M2 and the vacuum grooves communicating therewith are reduced. At this time, the squeegee roller 26B58 is squeezing around the area M2. For this reason, the photosensitive material 1 near the region M2 is
It is fixed at 0 by suction.

Next, the CPU 292 sets the origin to the origin by driving the photosensitive material sub-positioning motor M33 in reverse rotation (step S383). Next, it is determined whether the sub-positioning origin detection optical sensor SQ33 has been turned on (step S384). Next, the CPU 292 turns off the photosensitive material sub-positioning driving solenoids SL35a and SL35b of the sub-positioning units 27Fa and 27Fb (step S).
385). As a result, the stopper 27F5 moves upward. Thereby, exposure can be performed over the entire range of the photosensitive material 1.

Next, the details of step S5 will be described.
FIG. 26 is a flowchart showing details of step S5. In the light-sensitive material unloading mode, first, the CPU

That is, the path change transport unit 25 is raised to match the photosensitive material transport path of the transport unit 34. Thus, the photosensitive material 1 can be transported from the path change transport unit 25 to the transport unit 34.

Next, the CPU 292 executes a punching operation of the photosensitive material 1 (step S53). FIG. 27 is a flowchart showing details of step S53. First, C

7) Steps S536 and S537 are executed until the detection is performed. This is to prepare for the transfer of the photosensitive material 1 to the storage cassette 32, and when the photosensitive material 1 is discharged from the cylindrical inner drum body 22,
This is to prevent the punch units 27Ea to 27Ee from damaging the exposed surface of the photosensitive material 1. This is also to prepare for the sub-positioning and punch formation to be performed next time.

Next, the CPU 292 proceeds to step S54.
, The fixing of the photosensitive material 1 is released. That is, CPU

Therefore, when T3> TP3, the CPU 292 determines that a transport error has occurred in the photosensitive material 1 and displays an error on the monitor 41A. When T3 <TP3, the CPU 292 continues to rotate the transport motor M50. Thus, the photosensitive material 1 is continuously transported from the drive rollers 251a0 and 251b0 to the transport unit 34 side while being bent in an arc shape.

Next, the CPU 292 proceeds to step S57.
, The photosensitive material 1 is transported by the transport unit 34 and stored in the storage cassette 32. That is, the CPU 292

Close 20. Next, it is determined by the storage cassette door opening / closing detection optical sensor SQ68 whether or not the opening / closing door 320 is closed. If not closed, the CPU 292 determines that a storage error has occurred in the photosensitive material 1 and displays an error on the monitor 41A. If it is closed, the photosensitive material unloading mode ends, and the process returns to step S1 to step S3.

As described above, in the cylindrical inner surface scanning device shown in FIG. 1, the photosensitive material 1 fed from the guide roller 26A is attracted by the suction cup 26B57 near one side in the circumferential direction to rotate the rotation arm 26B5.
