Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a conveyance device that conveys a flexible long object at a certain position while adjusting the speed. It is used to continuously record a large number of frames by creating an image by shining a laser beam as a video signal on the part being conveyed at a certain speed in a main scanning state while adjusting the speed at a certain position. be done.

(Prior art) Conventionally, a device such as a photographic printer or an automatic processor is used to transport a flexible long object by adjusting its speed at a certain position, and the film is fed into an exposure area or a developing area (intermittently). ), a loop is formed in the film before the exposure and development sections, so errors and variations in film transport before the exposure and development sections do not affect the speed matching of the film in the exposure and development sections. It is known that this was done.

As mentioned above, when a flexible long object is conveyed at a speed in sub-scanning mode, and an image is formed and recorded by applying a laser beam to the speed-coordinating conveyance section in a main scanning state, high precision is required in the speed-coordinating conveyance. required.

Therefore, when conveying a flexible long object at the exposure section,
It is conceivable to form loops in the flexible long object at two locations, before and after the exposure section, prior to exposure, so that the conveyance state of the flexible long object before and after the loop does not affect the speed adjustment conveyance.

(Problems to be Solved by the Invention) However, if loops are formed on the flexible long object at two locations before and after the exposure area prior to exposure, approximately one loop is wasted each time exposure is performed. On the other hand, when exposure is done in a short single processing state such as one frame as a test, the wasteful consumption is more than the exposure of two frames, and the exposure is carried out continuously for many frames. Compared to continuous processing, the waste rate for flexible long objects is much higher.Moreover, if the formation of loops at the rear of the exposure section is stopped, it will be easier to match the speed at the exposure section with the speed at the rear transport section. Accurate image formation cannot be expected due to the influence of the conveyance state of the flexible long object.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention has the following features:
As shown in the figure, there are adjacent pairs of speed-coordinating conveyor rollers A and B that convey the flexible long object F at a processing position in a speed-coordinating manner, and the front and rear sides of each pair of speed-coordinating conveyor rollers A and B. A pair of front conveyance rollers C and a pair of rear conveyance rollers are arranged at a conveyance distance smaller than the division length in unit processing of a flexible long object and shorter than the effective unit processing length on the sides, and a pair of front conveyance rollers C are arranged in front of the pair of front conveyance rollers C. A cutter E for cutting a flexible long object is provided, and a preliminary conveyance means (2) capable of delivering the flexible long object F from this side to the front conveyance roller pair C is connected to the cutter E for cutting the flexible long object F. a conveyance mode setting means G for selecting a conveyance mode of conveying in a down position or conveying in parts; The control means H controls the operation of the I'U feeding means ■ and the cutter E, and when the control means H receives a signal to set the continuous conveyance mode from the conveyance mode setting means G, the control means H controls the operation of the flexible long object F. Loops F, , F are formed at two locations each between the speed-matching transport roller pairs A and B and the front transport roller pair C and rear transport roller pair before and after them.
, are formed, each pair of transport rollers A and B is moved so as to perform speed matching transport while maintaining the loops F1 and F2.
and controls the preliminary transport means I, and when receiving a signal to set the cutting transport mode, cuts the flexible long object F by the cutter E while sending out a predetermined cutting length from the position of the cutter E, and after cutting Each pair of conveyance rollers A, B, C, and D is driven again to convey the divided flexible object F, and the conveyance roller pair A is adjusted to the same speed.
, B is characterized in that the cutter E, each pair of conveyance rollers A, B5C1D, and the preliminary conveyance means (2) are controlled so that the conveyance is adjusted at the same speed in the sections B.

(Function) When the continuous conveyance mode is set by the conveyance mode setting means G, the control means H controls the speed matching conveyance roller pair AS.
Loops F1 and F2 are formed in the flexible long object F at two locations between the transport roller pair C and D before and after the conveyor roller B, and the flexible long object F is formed without maintaining the loops F and F2. Conveyance is controlled to match the speed. As a result, each pair of conveyance rollers A, B, C, D and the preliminary conveyance means (2) move the flexible long object F through the loops F, F, under the influence of the conveyance of the pair of conveyance rollers C, D before and after. A pair of conveyor rollers with no speed adjustment,
Continuous processing can be performed in a state where the speed is adjusted between B and B.

The control means H also divides the flexible long object F into a predetermined length from the cutter means E when processing the flexible long object F when the dividing conveyance mode is set by the conveyance mode setting means G. Each time it is conveyed, it is divided by a cutter E, and the divided flexible object of a predetermined length is transferred to each pair of conveying rollers A, B, and C.
The cutter means E, each pair of conveyance rollers A, B, C, and D, and the preliminary conveyance means (2) are controlled so as to convey at a speed of 1D. As a result, when processing the flexible long object F, the preliminary conveying means (2) conveys the flexible long object F by a predetermined dividing length from the cutter E, and sends it to the front conveying roller pair C. The attached divided flexible object is transported independently by each transport roller pair A, B, C1D, and between the speed matching transport roller pairs A and B, the arrangement interval of each transport roller pair A, B, C1D and the flexible In relation to the length of dividing the long object F and the effective processing length,
The divided flexible object can be reliably received from the front conveyance roller pair C and reliably passed to the rear conveyance roller pair, and at least most of the effective processing length of the divided flexible object can be transferred to the speed matching conveyance roller. While the flexible object is between pairs A and B, the flexible object is separated from the front and rear transport roller pairs C and D, and the flexible object is separated at the same speed as not being affected by the front and rear transport conditions. The effective processing range of objects can be subjected to necessary processing.

Main scanning is performed in the direction orthogonal to the conveyance direction of the roll-shaped photosensitive material 1 on the portion of the roll-shaped photosensitive material 1 that is conveyed at the same speed between the third and fourth conveyance roller pairs 10 and 11. The photosensitive material 1 is irradiated in such a manner that a large number of frames are continuously formed and recorded on the roll-shaped photosensitive material 1.

Also, on the left side of the part forming each loop 1a, 1b,
Temporary conveyance guides 18a and 18b are provided which can be opened and closed, respectively, and when they are bridged as shown by the imaginary lines in FIG. This allows the formation of loops 1a and 1b of the rolled photosensitive material 1.

The main body 3 further includes a microcomputer (

Control is carried out in a continuous conveyance mode in which the roll-shaped photosensitive material 1 is continuously formed and subjected to processing, and controlled in a divided conveyance mode in which the roll-shaped photosensitive material 1 is conveyed in sections of a predetermined length and subjected to processing independently. control.

The predetermined dividing length is, for example, about 200 mm, which corresponds to the image length of one frame, and the predetermined dividing length is approximately 200 mm, which corresponds to the image length of one frame.
The distance between the pair of conveyance rollers 10 and the distance between the second pair of conveyance rollers 9 and the fourth pair of conveyance rollers 11 are set to be smaller than the predetermined dividing length and larger than the effective exposure length, and the distance between the pair of third conveyance rollers 10 and the fourth pair of conveyance rollers *The distance between the pair of feed rollers 11 is such that it can be exposed to the laser beam 2. The speed relationship of each pair of conveyance rollers 8.9.10.11 in the divided conveyance mode is such that the first conveyance roller pair 8≧3rd and 46th conveyance roller pair 10.11≧2nd R conveyance roller pair 9.

In place of the winding type pickup magazine 6 shown in FIG. 2, the main body 3 can be equipped with a dividing processing magazine 22 that can accommodate the divided photosensitive material 1c as shown in FIG. A magazine detection switch 24 detects whether the magazine is not mounted.

A series of operations will be explained below.

Firstly, Ren Vt! The case of normal printing in the Il feed mode will be explained based on the operation control flowchart shown in FIG. Then, the lead portion of the roll-shaped photosensitive material l drawn out from the delivery port is bitten by a pair of preliminary conveying rollers 23. At this time, for example, the upper roller of the pair of preliminary conveying rollers 23 is released from the pressure contact or separated (this makes the operation easier. Although the lead portion of the roll-shaped photosensitive material 1 in the supply magazine 5 is pulled out, the conveying port remains closed. It is in an internal light-shielded state, and only the lead portion is exposed to external light.

Next, after returning the pair of preliminary conveying rollers 23 to the pressed state, the main body 3 is closed, and the entire main body 3 is placed in a light-shielding state. At this time, if the pick-up magazine 6 is loaded and set correctly, the microcomputer 21 does not receive the ON signal from the switch 24 because the cutting magazine 22 is not installed, so it immediately executes "READ" in step #1.
Y” is displayed on the operation panel.

Then, when the print switch is turned on, it is detected in step #2 and the process moves to step #3. At this time, the shutters of the respective transport ports of the supply magazine 5 and the tick-up magazine 6 are opened, and the light shielding by the shutters of the joints between the transport means 7 of the main body 3 and each magazine 5.6 is also released.

At this time, a conveyance path is formed by the conveyance means 7 from the supply magazine 5 to the pick-up magazine 6, and the conveyance guide plates 18a and 18b are placed in a bridging state as shown by the imaginary line in FIG.

In this state, the driving of the first, second, third, and fourth conveyance roller pairs 8.9.10.11 and the preliminary conveyance roller pair 23 in step #4 is basically performed in a synchronous state. As a result, the roll-shaped photosensitive material 1 whose lead portion is caught between the first pair of conveying rollers 8 is conveyed in a straight line by the conveying means 7. The roll-shaped photosensitive material 1'' is transferred to the second conveying roller pair 9.
When the value reaches , the photosensitive material detection switch 14 is turned on. When the on of this switch 14 is detected by Ste knob #5,
Proceeding to step #6, the second, third, and fourth conveyance roller pairs 9.10.11 are stopped.

Subsequently, in step #7, the conveyance guide plate 18a bridging between the eleventh and third conveyance roller pairs 8 and 10 is opened to a solid line state.

As a result, the rolled photosensitive material 1 that continues to be transported by the preliminary transport roller pair 23 and the first transport roller pair 8 is transferred to the first!11th transport roller pair 8 and the third! gl
It gradually hangs down between the pair of feed rollers 1o, and a loop 1a is formed extending to the left. When the loop 1a reaches a predetermined size, the loop detection switch 15 is activated, and the formation of the loop 1a is confirmed in step #8.

When the formation of the loop 1a is confirmed, the process moves to step #9, and the driving of the third and fourth conveying roller pairs 10 and 11 is restarted in synchronization with the first conveying roller pair 8, and then the process proceeds to step #10.
Then, the conveyance guide plate 18b bridging between the second and 4111th conveyance roller pairs 9.11 is opened. As a result, the roll-shaped photosensitive material 1 is transported at almost the same speed before and after the loop 1a, and while maintaining the loop 1a, the roll-shaped photosensitive material 1 is transported by the preliminary transport roller pair 23 and the first, third, and fourth transport roller pairs 8.10.11. After being conveyed, it gradually hangs down between the second conveying roller pair 9 whose conveyance is still stopped, and another loop 1b is formed extending leftward. When the loop 1b reaches a predetermined size, the loop detection switch 16 is activated. switch 16
As a result of the operation, the formation of the loop 1b is confirmed in step #11.

At this time, loops la and 1b are formed in the rolled photosensitive material 1 before and after each of the third and fourth conveying roller pairs 10 and 11 that carry out highly accurate speed matching conveyance as sub-scanning, and thus loops la and 1b are formed in the roll photosensitive material 1 in step # 12, the first, third,
Driving in synchronization with each of the fourth transport roller pairs 8.10.11 is restarted. As a result, the roll-shaped photosensitive material 1 having two loops 1a and 1b as shown in FIG. 2 is conveyed while maintaining the loops 1a and 1b, and the third
, a state in which the conveyance between the fourth pair of conveying rollers 10.11 is not affected by errors, variations, or vibrations in the conveying speed in the preliminary conveying roller pair 23 before and after the fourth pair of conveying rollers 10.11, and the first and second conveying roller pairs 8.9. becomes.

Therefore, each of the third and fourth conveying roller pairs l0111 can regulate the conveying speed of the long roll of photosensitive material 1 at a predetermined position only by controlling their own speed.
Highly accurate speed-matched transport for exposure is possible.

Then, the process moves to step #13, where the laser optical system 13 is put into operation, and the portion of the roll-shaped photosensitive material 1 that is conveyed at the same speed between the third and fourth pairs of conveyance rollers 10.11 is exposed. With the start of exposure, the winding operation of the roll-shaped photosensitive material 1 in the tick-up magazine 6 is started in step #14, and when the roll-shaped photosensitive material 1 is fed in, it is automatically wound up. .

During exposure, the sizes of the loops la and lb of the rolled photosensitive material 1 are controlled to be within a predetermined range.

Specifically, if the loop 1a becomes larger, the speed of the preliminary transport roller pair 23 and the first transport roller pair 8 is lowered, and if the loop 1a becomes smaller, the speed of the preliminary transport roller pair 23 and the first transport roller pair 8 is increased. . Further, if the loop 1b becomes larger, the speed of the second* feed roller pair 9 is increased, and if the loop 1b becomes smaller, the speed of the first transport roller pair 8 is decreased. As a result, the sizes of the loops la and lb are kept constant regardless of the highly accurate speed-matched conveyance by the third and fourth pair of conveying rollers 10 and 11, and the sizes of the loops la and lb are kept constant, and It is possible to prevent the conveyance state of the pair 8.9 from affecting the speed matching conveyance between the third and fourth conveyance roller pairs 10.11 from beginning to end.

Instead of such control, the preliminary conveyance roller pair 23, the first
, the second pair of conveying rollers 8.9 is set a little faster than the third and fourth pair of conveying rollers 10.11, and the loop 1a is
This can also be done by turning off the preliminary conveying roller pair 23 and the first conveying roller pair 8 when the loop 1b becomes large, turning them on when it becomes small, turning on the second conveying roller pair 9 when the loop 1b becomes large, and turning them off when it becomes small.

When the exposure is completed by a signal such as completion of exposure of the set number of frames, operation of the exposure stop switch, or completion of imaging from the tomography device, this is confirmed in step #15, and the process moves to step #16, where the preliminary conveyance roller pair is 23, 1st, 2nd
, the driving of the third and fourth conveying roller pairs 8.10.11 is stopped. Next, in step #17, "Capturing possible" is displayed on the operation panel. After confirming that the cut switch is turned on in step #18, step #19
to operate the cutter 12 and cut the roll of photosensitive material l.
cut. This cutting operation can be performed automatically by setting a cut signal when setting the necessary print i, for example, and when a predetermined amount of printing is completed and the loop 1aSlb is eliminated.

Next, move to step #20 and tick up magazine 6
The winding operation is restarted, and the exposed side of the roll of photosensitive material I is wound up into the tick-up magazine 6 up to its cut end. The end point of this winding can be known from the winding operation time, the amount of operation, etc., and after the winding is completed, the winding of the tick-up magazine 6 is stopped and the winding is completed.

After confirming the completion of this winding in step #21, step #
22, the transport ports of the supply magazine 5 and the pick-up magazine 6 are closed, and the shutters at the joints between the transport means 7 of the main body 3 and each magazine 5.6 are closed, and each magazine 5.6, The interior of the main body 3 is shielded from light.

Due to this internal light shielding, the process moves to step #23, and a "door open" message is displayed on the operation panel. Thereafter, by confirming that the door oven switch is turned on in step #24, the door is unlocked in step #25, allowing the door to be opened, and step #26
It is possible to take out the magazine.

When the pick-up magazine 6 is taken out, the exposed photosensitive material 1 stored therein can be subjected to development.

When the pickup magazine 6 is loaded into the main body 3 again and the door of the main body 3 is closed to block light, the main body 3 is returned to the "READY" state in which printing is possible.This is based on the operation control flowchart in FIG. In step #31, the loaded tick-up magazine 6 is set to a windable state, and then, in step #32, it is confirmed whether the main body 3 is shielded from light by closing the door.

After confirming that the main body 3 is shielded from light, the process moves to step #33, where the self-diagnosis function of the main body 3 is activated to confirm the position of the roll-shaped photosensitive material 1, return the transport guide plates 13a and 18b to the closed state, and confirm the initial state. do. This is to take into account recovery after troubles such as jams.

In the next step #34, it is determined whether the initial condition is good or bad as a result of the self-diagnosis, and if it is bad, the process moves to step #36 and an "alarm" is displayed to prompt re-inspection. If the
DY'' is displayed.

Then step # that the print switch was turned on
If confirmed in step #37, the process moves to step #38, in which the shutters of each transport port of the supply magazine 5 and the pick-up magazine 6 are opened, and light is also blocked by shutters at the joints between the transport means 7 of the main body 3 and each magazine 5.6. It will be canceled.

This is the same as step #4 during normal printing, but now the tick-up magazine 6 during normal printing.
When the photosensitive material 1 is reset, the rolled photosensitive material 1 has reached the position where it was cut by the cutter 12 in FIG.
All you need to do is form lb, and in preparation, step #38
Now, close the conveyance guide plates 18a and L8b. Next, the process moves to step #39, and the preliminary conveying roller pair 23 and the first, third, and fourth conveying roller pairs 8, 10, and 11 are synchronously driven to convey the rolled photosensitive material 1.

When the roll-shaped photosensitive material 1 reaches the second transport roller pair 9 and the switch 14 is turned on, this is confirmed in step #40. This is the same state as when step #5 is completed during normal printing, and the operations from step #6 during normal printing are repeated.

Second, to explain the case of the divided conveyance mode in which the divided processing magazine 22 is loaded and one frame is test exposed, the rolled photosensitive material l from the supply magazine 5 is in the normal print state in the continuous conveyance mode. Similarly, it is assumed that the pair of preliminary conveying rollers 23 is caught. Here, when the dividing processing magazine 22 is installed and set correctly as shown in FIG. , lint” is displayed. From this point on, printing in the continuous processing mode is not performed, and only printing operations in the divided conveyance mode according to the flowchart in FIG. 6 are performed. Note that if the dividing processing magazine 22 is not installed, no receiver is attached for printing in the dividing conveyance mode, and only printing operations in the continuous conveyance mode shown in FIGS. 4 and 5 are performed.

“After test print 3 is displayed, if it is confirmed in step #43 that the test print switch is on, step #44
to move to. At this point, the shutters of the respective transport ports of the supply magazine 5 and the cutting processing magazine 22 are opened, and the light shielding by the shutters at the joints between the transporting means 7 of the main body 3 and each magazine 5.22 is also released, and the cutting processing is carried out from the supply magazine 5. After the conveyance path to the magazine 22 is completed, the process moves to step #45, and the first, third, and fourth conveyance roller pairs 8, 10, and 11 are driven at the speed relationship in the divided conveyance mode. The preliminary transport roller pair 23 is driven in synchronization with the first tIl transport roller pair 8. As a result, when the roll-shaped photosensitive material 1 is conveyed by a predetermined dividing length from the position of the cutter 12, this is detected in step #46. This detection is performed using a timer, the number of rotations of the transport port 1-RA pair, a switch provided at a predetermined position, or the like. In the illustrated embodiment, the roll-shaped photosensitive material 1 has reached the third pair of transport rollers 10, as shown in FIG.

When conveyance for a predetermined dividing length is confirmed, the process moves to step #47, where the roll-shaped photosensitive material 1 is cut and divided. After dividing, in step #48, the preliminary conveyance roller pair 23 is stopped, and the subsequent feeding of the roll-shaped photosensitive material 1 is stopped. Separated photosensitive material (divided flexible material) lc is the first, second, third, fourth
As each pair of transport rollers 8.9.10.11 continues to be driven, the paper is further transported.

As a result, when the divided photosensitive material 1c is bitten by the third and fourth conveying roller pairs 10 and 11 as shown in FIG.
1 is turned on, which is confirmed in step #49. After this confirmation, the process moves to step #50, and after waiting for the divided photosensitive material 1c to be separated from the first pair of transport rollers 8 using a timer or the like, exposure is started as shown in FIG. 9. The first conveying roller pair 8 and the third conveying roller pair 10 may be at the same speed in an ideal state, but it is difficult to expect the same speed state, and vibrations of the first Va conveying roller pair 8, etc. In order to prevent this from being transmitted, it is preferable to set the first pair of conveying rollers 8 to be a little faster than the third pair of conveying rollers 10. As a result, the divided photosensitive material 1c hangs slightly between the first and third conveying roller pairs 8.10 as shown in FIG.
In addition to absorbing the speed difference, vibrations of the first Va feed roller pair 8 are also absorbed. For the same reason, it is preferable to create a speed difference between the fourth pair of conveying rollers 11 and the second pair of conveying rollers 9 by making the second pair of conveying rollers 9 a little slower than the 4111th pair of conveying rollers 11. Exposure is divided photosensitive material 1
The third and 41st fa feed roller pairs 10 and 11 are used to convey the divided photosensitive material 1c alone during exposure, and the other conveyance rollers are Exposure can be performed in a speed-adjusted conveyance state that is not affected by the area.

After the exposure, the leading end of the divided photosensitive material 1c reaches the second pair of conveying rollers 9 and begins to be conveyed by the second pair of conveying rollers 9, but as shown in FIG. By creating a sag between the roller pairs 9 and 11, the conveyance state by the second conveyance roller pair 9 is prevented from affecting the fourth conveyance roller pair 11.

When the divided photosensitive material 1c is bitten by the second conveying roller pair 9, it is rJ*L'2 in step #51, and in the next step #52, it is transferred by the 2111th conveying roller pair 9 after exposure. The divided photosensitive material 1c is stored in the dividing processing magazine 22 as shown in FIG. If multiple test prints are set, it is determined in step #53, and if the test print is not completed, the process returns to step #45.
The next test print is repeated. Upon confirmation of the completion of the test print, the process moves to step #54, where the transport means 7 of the main body 3, the supply magazine 5, and the cutting magazine 22
The shutter of the communication section with the magazine 5.22 is closed, and the transport port of each magazine 5.22 is also closed. As a result, the interior of the main body 3 and each magazine is shielded from light.

Next, in step #56, a "door open" display is displayed on the operation panel, and when it is confirmed that the door open switch is on in step #57, the door is unlocked in step #58, allowing the door to be opened6. Next, the process moves to step #59, and the magazine 5.22 can be taken out.

When the dividing processing magazine 22 is taken out, the divided photosensitive material 1c on which test printing has been performed can be handled individually and subjected to a phenomenon.

(Effects of the Invention) According to the present invention, since it has the above-mentioned structure and operation, a flexible long object can be formed in a loop at the front and rear to prevent it from being influenced by other conveyance parts, and can achieve highly accurate speed adjustment. It can be subjected to various continuous treatments. In addition, when subjecting the flexible long object to unit processing, the flexible long object is divided into one unit and handled by a speed-matching conveyance section whose interval is slightly shorter than the divided length, and conveyance sections before and after it. , while ensuring the cross-over between the front and back of the speed-matching transport section for the divided flexible object, the speed-matching transport section transports the divided flexible object independently with little or no relation to the front and rear transport sections, and exposes the divided flexible object in a highly accurate speed-matching transport state.
