In FIG. 1, P1 to P3 are photographic light-sensitive materials (hereinafter simply referred to as paper), G1 to G7 are width guides, R1 to R7.
Is a rack, K1 to K7 are sensors, and S1 to S7 are guide width changing means.

The processing apparatus 1 is provided with a color developing tank 2, a bleaching tank 3, a fixing stabilizing tank 4, and a drying unit 5, and supports a conveying roller (not shown) for conveying paper and width guides G1 to G7 to be described later. Racks R1 to R7 are provided in each processing tank and the drying unit. A lower path 9 for transporting the paper inserted from above into the rack R1 downward.
And an upper path 10 for conveying upwards are arranged side by side, and both paths 9 and 10 are connected by a lower turn guide 11. The racks R2 to R7 have the same configuration. The upper path 10 of the rack R1 and the lower path of the rack R2 are connected by an upper turn guide 12. Each rack R2 to R7
Has a similar configuration.

Papers P1 to P3 are papers such as photographic paper on which image frames of a photographic film are printed.
Before being cut for each frame, it is wound in a roll,
It is inserted from the insertion port 6 of the processing apparatus 1 in a belt-like state, processed through the processing tanks 2 to 4, dried in the drying unit 5, discharged from the discharge port 7, and then cut by one frame. Is done.

In FIG. 2, the width guide G is formed by attaching a pair of members having a U-shaped cross section to the screw shaft 21 so as to face each other. The screw shaft 21 is formed by coaxially connecting a shaft formed with a right-hand thread and a shaft formed with a left-hand thread on the outer periphery, and a nut 22 is screwed into each of the right-hand thread part and the left-hand thread part. . The width guide G is attached to the pair of nuts 22, and the width guide G is moved in the axial direction of the screw shaft 21 by rotating the screw shaft 21, thereby changing the guide width. A bevel gear 23 is fitted to one end of the screw shaft 21,
A spur gear 26 is attached to the upper end of a shaft 25 having a bevel gear 24 at the lower end that meshes with the bevel gear 23, and meshes with a spur gear 28 fitted on a drive shaft of a control motor 27. By driving the control motor 27, the screw shaft 21 rotates to change the guide width of the width guide G.

The width guide G and the screw shaft 2
1 and a shaft 25 are provided on a rectangular cylindrical rack R, and an upper cover 30 of the processing apparatus 1 indicated by a two-dot chain line.
Is closed, the spur gears 26 and 28 mesh with each other, and the guide width of the width guide G can be changed by the dedicated control motor 27.

In the embodiment shown in FIG. 1, each rack R1
To R7 and sensors K1 to K7 and guide width changing means S1
S7 are attached, and the width guides G1 to G7 are
The guide width can be changed for each of 1 to R7.

For example, in FIG. 1, a width guide G1 indicated by oblique lines rising to the right has a guide width W3, and width guides G2, G3 and G4 indicated by blanks have a guide width W2.
, Width guides G5 and G indicated by oblique lines
6, G7 are each adjusted to the guide width W1. The paper P1 inserted from the insertion slot 6 is moved to the racks R5 and R5.
It is assumed that the vehicle is passing through No. 6. At this time, the width guides G5 and G6 are adjusted to the width W1 of the paper P1, and it is known that the width guide G7 also passes through P1 after the previous paper is completely removed. Has been adjusted. The guide G4 is adjusted to the width W2 of the next paper P2 since the sensor K4 detects that the paper P1 has passed through the rack R4. Paper P2
Is sent out to the racks R1, R2, R3 and R4, and after the sensor K1 detects that the rear end has passed through the rack R1, the guide width of the width guide G1 of the rack R1 is changed to the paper P3 to be inserted next. Is changed to the width W3. Then, the next paper P3 can be inserted immediately. Similarly, racks R1, R2, R3, R4, R5, R
The guide width is changed in the order of 6, R7, and paper P
3 is discharged from the discharge port 7. Thus, paper P
Since the guide width is automatically changed sequentially in accordance with the progress of 1 to P3, it is possible to continuously insert the paper into the processing apparatus 1 only after the time when the rear end of the paper passes through one rack. it can.

Next, a control block diagram of the arithmetic unit will be described with reference to FIG. The paper detection sensor detects the position of the paper. The detected paper position is input to the CPU. On the other hand, the width information of the paper to be processed next is input to the CPU, and an appropriate guide width of each width guide is calculated, and the guide width changing means S1, S
Drive the control motor 27 of the width guide G
Are changed to appropriate values. The width of the paper may be individually detected by a width detection sensor or the like, and this information may be sent to the CPU.

Further, a control flowchart will be described with reference to FIG. When the guide width of the width guide is calculated, the guide width of each width guide is checked. If the width is appropriate, pass the paper as it is. If the width is not appropriate, the control motor of the width guide is operated to change the width to an appropriate width, and the width is checked again. When the width becomes appropriate, stop the control motor and wait for the paper to pass. When the sensor detects the paper and the passage is confirmed, the width of the next paper to be passed is calculated, the control motor of the width guide is operated, the guide width of the width guide is changed, and the next paper is passed. Wait for.

Although the embodiment shown in FIG. 1 changes the guide width for each rack, the rack is further divided as shown in FIG. 5 (in the embodiment shown in FIG. 5, the rack is divided into four parts). However, the number may be divided into different numbers.) Then, when the trailing end of the previously inserted paper has passed the 1/4 rack path in the example of FIG. 5, the next paper can be inserted, which is more efficient. In this case, a sensor and a guide width changing means are provided for each unit (one of the four divisions is shown). Also, the racks R1 and R2, R3 and R in FIG.
4. R5 and R6 may be combined and the guide width may be changed for each processing tank. Furthermore, racks R1, R2, R
Blocks may be configured with each processing tank and drying unit as in Nos. 3 and R4, and R5, R6 and R7, and the guide width may be changed for each block. In this case, similarly, a sensor and a guide width changing means are provided for each unit constituted by the processing tank or the block.

Also, without attaching the sensors K1 to K7 in FIG. 1, the time when the rear end of the previously inserted paper finishes passing through each unit is calculated, and after that time, the width of the next inserted paper is calculated. May be changed. That is, the speed at which the paper is transported in the processing apparatus is V, the length of the paper to be inserted first is L, and the path length of each unit is T1, T1.
2, T3,... Therefore, if the paper to be inserted first is inserted at 0:00, the first unit is (L +
At (T1) / V, the second unit is (L + T1 + T2)
/ V, the width is changed to the width of the paper to be inserted next.

[0020]

When a paper having a width different from that of the paper previously inserted into the processing device is next inserted into the processing device,
Previously, the next paper could not be inserted until the previous paper was completely discharged from the processing device.
According to the transfer method and the transfer device of the present invention, the width guide in the processing device is divided into several width guide units,
Since the guide width can be changed for each unit, the next paper can be inserted as soon as the previous paper passes through the unit. Therefore, the paper can be continuously inserted into the processing apparatus only by leaving an interval for one unit path, so that the time efficiency is dramatically improved.
