[Example] Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a schematic diagram of a photographic paper processing system including a photographic paper alignment device of the present invention.

A strip of photographic paper 1 is conveyed by a conveyance roller 2 and cut by a cutter 3 to form a sheet of photographic paper 4. This sheet-shaped photographic paper 4 is conveyed to an image printing section 5, where the photographic paper 4 is exposed to an image. The exposed photographic paper 4 is carried into a photographic paper sorting device 6 disposed at a temperature subsequent to the image printing section 5. In this photographic paper sorting device 6, sheet-shaped photographic paper 4 is supplied to conveying means 8 of an automatic developing machine 7. This conveying means 8 conveys the sheet-shaped photographic paper 4 sorted into a plurality of conveyance lines in parallel at predetermined conveyance intervals, and the developing section 9 carries out development processing. After this treatment, the photographic paper 4 is dried,
A conveying roller 11 arranged at the outlet section 10 of the automatic developing machine 7
will be removed from.

A plurality of detection means 12 are disposed at the exit section 10 of the automatic developing machine 7, and detect the photographic paper 4 conveyed by each conveyance line of the conveyance means 8. This detection means 12 is composed of a transmission type optical sensor, but a reflection type optical sensor may also be used.

When the detection means 12 detects conveyance of the photographic paper 4, this detection signal is sent to the control means 13, which is constituted by a microcomputer.

The control means 13 drives the transport means 14 based on the detection signal of the photographic paper 4 obtained by the detection means 12 to convey the photographic paper 4 in alignment. The transport means 14 receives the photographic paper 4 on each transport path carried out from the transport means 8 and transports it to a sorter.

This photographic paper aligning device is constructed as shown in FIGS. 2 to 4. FIG. 2 is a perspective view of the photographic paper aligning device, FIG. 3 is a front view of the photographic paper aligning device, and FIG. 4 is a photographic paper aligning device. FIG. 3 is a side view of the alignment device.

The photographic paper 4 carried out from the conveyance roller 11 sequentially falls onto the photographic paper holder 15 of the transport means 14.

The photographic paper holder 15 is arranged to have the width of the conveyance path of the photographic paper 4 and at right angles to the conveyance direction of the photographic paper 4. This photographic paper holder 15 is provided with an opening 16 in the direction of horizontally feeding the photographic paper 4, and a horizontally feeding claw 17 projects from this opening 16.

As shown in FIG. 3, this horizontal feed claw 17
Heald 19 of the cross-feeding conhair 18 placed inside 5
is protruding from the outer surface of the The horizontal feed conveyor 18 is driven by a drive motor 20, and the horizontal feed claw 17 moves along the opening 16 as the heald 19 rotates within the photographic paper holder 15, thereby horizontally conveying a predetermined number of photographic papers 4. , onto the sorter blades 22 of the sorter conveyor 21 disposed at the end of the photographic paper holder 15.

A stopper 23 is provided at a position corresponding to the sorter blade 22 of the sorter container 21 to prevent the photographic paper 4 carried out from the photographic paper holder 15 side from falling.

In order to prevent the photographic paper 4 that is being fed horizontally by the horizontal feed claw 17 from catching on the photographic paper 4 that has been carried out from another conveyance line and falls onto the photographic paper holder 15, the photographic paper 4 that falls on each conveyance line is
It is necessary to leave a predetermined conveyance interval.

Further, as shown in FIG. 4, the distance h between the photographic paper holder 15 and the conveying roller 11 is 1/3 of the length of the photographic paper 4 in the conveying direction.
It is preferable to open more than that. In addition, in order to smoothly carry out the accumulated photographic paper 4 from the photographic paper holder 15 onto the sorter blade 22, the head height m between the stacked photographic papers 4 in the horizontal feeding direction is set as shown in FIG. It is preferable that the thickness of the photographic paper be 115 or more, or greater than the thickness of the photographic paper corresponding to the maximum number of sheets of photographic paper that can be accommodated in one soter blade 22.

Next, a method for aligning and feeding the photographic paper 4 falling from the conveying roller 11 will be described.

As mentioned above, a plurality of detection means 12 are arranged at the exit section 1o of the automatic developing machine 7 in correspondence with the conveyance rows, and when the photographic paper 4 conveyed out by the operation of the conveyance means 8 is detected here, The detection signal is sent to the control means 13. After a certain period of time has elapsed since this detection signal was sent, the photographic paper 4 falls onto the photographic paper holder 15.

The control means 13 sends a control signal to the transport means 14 to drive the lateral conveyor 18 in accordance with the falling time of the photographic paper 4.
The horizontal feed claw 17 is moved to its dropping position.

Under the control of the control means 13, each time a sheet of Ep drawing paper 4 falls, it is immediately conveyed to the sorter blade 22 by the horizontal feed claw 17.

In this case, the travel time required to pass the horizontal feed claw 17 or the adjacent transport line is shorter than the time from when the nth photographic paper falls until when the next (n+1)th photographic paper falls. It is necessary.

In this case, each time a sheet of photographic paper 4 falls, it is immediately conveyed to the sorter blade 22 by the lateral feed claw 17, so that the alignment of the photographic paper 4 is not affected by slight meandering in the automatic processor 7.

Similarly, under the control of the control means 13, after the n-th photographic paper 4 is received by the horizontal feed claw 17 in the first conveyance line farthest from the vine conveyor 21, the following second and third conveyance lines receive the nth photographic paper 4. Also in the transport line, it is possible to receive the (n+1)th and (n+2)th photographic papers 4, combine the above three sheets, and then carry them out to the sorter blade 22 at °C.

In this case, after putting together three sheets of photographic paper 4,
Since the horizontal feed claw 17 has a short distance to move each time and the time required for the movement to be shortened, there is less risk of catching the photographic paper 4 falling from another conveyance path during the transfer, making control easier. .

Further, under the control of the control means 13, the horizontal feed claw 17 is moved back and forth in the conveyance direction, and the photographic paper 4 is accumulated in one order unit, for example, 12, 24, or 36 sheets, and then the sorter blade 22 It may be transported to

In this case, since the photographic paper 4 for the ordered unit is stacked on the horizontal feed claw 17 and then conveyed in alignment, it is possible to eliminate the need for checking the boundaries of the - ordered unit again.

Further, upper and lower conveyance rollers 11 disposed in the automatic developing machine 7
can be configured so that the rear end of the photographic paper 4 can be easily separated.

In the embodiment shown in FIGS. 5 and 6, the upper conveyance roller 11 is formed as a columnar roller, but the lower conveyance roller 11 has an axial protrusion +1a.
1a and the rear end of the photographic paper 4 Qj:l 4a is pushed out to the outside to make it easier for the rear end 4a of the photographic paper 4 to separate from the conveying roller 11. This makes it possible to stabilize the time from when the detection means 12 provided at the exit detects the photographic paper 4 until the photographic paper 4 falls at the exit.

In the embodiment shown in FIG. 7, the lower conveyance roller 11 has circular protrusions 11a formed at predetermined intervals, and these protrusions 11a push the rear end of the photographic paper 4 outward in the same manner as described above. Therefore, it is possible to easily separate the rear end of the photographic paper 4 from the conveyance roller 11.

That is, for example, as shown in FIG. 8, if a conveying roller 11 that is flat at both the top and bottom is used, the rear end 4a of the photographic paper 4 may slip and the photographic paper 4 may not fall, and the detection means 12 may detect the photographic paper 4. The time from when the photographic paper 4 is detected to when it falls at the exit varies, but as shown in Figs. 5 to 7,
By configuring the conveyance roller 11, the time from when the photographic paper 4 is detected to when the photographic paper 4 falls at the exit can be stabilized with a simple structure.

In the embodiment shown in FIGS. 9 and 10, the upper conveyance roller 11 is similarly formed as a columnar roller, but the lower conveyance roller 11 has a plurality of disc-shaped rollers Ilb arranged at intervals. This disc-shaped roller 11
A guide 70 is disposed between the parts 1 and 2b, and this guide 70 is attached to an exterior plate 71.

The photographic paper 4 transported by the upper and lower transport rollers 11 falls from the open lower door 2 provided on the exterior plate 71, but the paper 4 is transported by the upper and lower transport rollers 11.
Since the space between the plurality of disc-shaped rollers Ilb and the outer plate 71 is covered by the guide 70, the trailing end 4a of the fallen photographic paper 4 is wound inside the outer plate by the conveying roller 11. Never.

That is, as shown in FIG. 11, for example, when the photographic paper 4 is conveyed by the flat conveyance roller 11 and dropped from the opening lower part 2 of the exterior plate 710, the rear end 4a of the photographic paper 4 or the exterior plate 71 If the photographic paper 4 does not fall, or the rear #64a of the photographic paper 4 may be caught by the conveyance roller 11, the structure shown in FIGS. 9 and 10 prevents the photographic paper 4 from falling. Defects and entanglements are prevented.

In addition, the lower conveyance roller 11 shown in FIGS. 9 and 10
Protrusions 11a as shown in FIGS. 5 to 7 are provided on the surfaces of the plurality of disc-shaped rollers 11b, and after the detection means 12 detects the photographic paper 4, the photographic paper 4 exits and falls. It is possible to stabilize the time.

Further, the feeding angle of the photographic paper 4 on the conveyance roller 11 is set upward from the horizontal, and the photographic paper 4 is placed on the photographic paper holder 15.
Make sure that the tip does not hang down.

In this embodiment, the detection means 12 is provided at the outlet section 10 of the automatic processor 7, but it can also be provided at the transfer means 14.

In this case, a microswitch 120 is used as the detection means 12.
In the case of using a photographic paper 4, the photographic paper 4 is placed in contact with the photographic paper 4 as shown in FIG. In addition, the detection means 12
When using the reflective photoelectric sensor 130 as the first
As shown in FIG. 3, a light projecting section 130a and a light receiving section 130b are arranged at positions facing the falling photographic paper 4.

In this embodiment, the photographic paper 4 to be carried out to the photographic paper holder 15 is conveyed in alignment using the horizontal feed claw 17, or as shown in FIG. 4 may be taken out and directly aligned and conveyed using the traverse conveyor 30.

Further, as shown in FIG. 15, a stopper 31 is placed on the transverse conveyor 30, and the photographic paper 4 is carried out from the conveyance roller 11 onto the transverse conveyor 30, and aligned and conveyed by the stopper 31.

The transverse conveyor 30 shown in FIGS. 14 and 15 is also driven under the control of the control means 13, and similarly to the above, it transports the photographic papers 4 one by one or accumulates a predetermined number of photographic papers 4. By rotating forward and backward, an arbitrary number of photographic papers 4 can be stacked and then delivered to the sorter blade 22.

[Effects of the Invention] As described above, the present invention distributes sheet-shaped photographic paper into a plurality of transport lines, uses a detection means to detect the photographic paper being transported while maintaining a predetermined transport interval, and detects the detection signal. Based on this, the control means drives the transfer means to sequentially align and transfer the photographic papers in each conveyance line.

Therefore, since it does not have a gate device for aligning and conveying the photographic paper as in the past, the structure is simple, and the conveying means is continuously driven without being driven intermittently to align the photographic paper. Since the printing paper can be carried out sequentially and conveyed in line, high-speed processing of photographic paper becomes possible.

Furthermore, since it is possible to carry out aligned conveyance without using a conventional gate device that is driven independently according to the conveyance path, it is ideal for aligned conveyance of photographic paper of various sizes.
