Thus, the suction drum 146 becomes 1
The second disk 236 makes one rotation each time it rotates, and the first disk 228 makes one rotation every time the suction drum 146 makes two rotations. Accordingly, if the long photographic film 110 corresponding to the length of the half-size photographic film strip 18 + α is sent out each time the suction drum 146 makes one rotation, the first disk The first origin signal Sg1 corresponding to the full size is output from the optical sensor 238 corresponding to 228, and the second origin signal Sg1 corresponding to the half size is output from the optical sensor 240 corresponding to the second disk 236.

It will be cut as a full size photographic filmstrip 18.

When the long photographic film 110 is cut into half-size photographic film strips 18, the clutch 300 includes a roller gear 290 connected to a fourth speed reducer 282 and an arm 296 extending from the film cutter unit 294. Are connected via. Thus, each time the suction drum 146 makes one rotation, the film cutter 1

As described above, the suction drum 146, the origin signal generating means 210, the start signal generating means 260 in the first sub-control unit 180, the transport belt 150, and the film cutter 148 are sent out from the film roll 116A or 116B. The long photo film 110 functions as a film cutting unit that cuts the long photo film 110 into a length suitable for the film size (full size or half size) included in the film information.

As shown in FIG. 7, the film cutter 148
A conveyor device 312 that is controlled by the second sub-control unit 310 and that conveys the cut photographic filmstrip 18 to the subsequent conveyance line 108 is provided downstream of the conveyance direction of the photo film strip 18. The downstream transport line 108 is composed of a main line 314 that transports the photographic film strip 18 in one direction and a plurality of branch lines 316 that branch off from the main line 314 and supply the light-shielding paper strip 20 and the spool 16. I have. The main line 314 is composed of a plurality of sets of conveyor belts, and each branch line 316 is provided with a tape attaching section 332 described later.
The transport path up to is constituted by a transport belt.

Main line 314 of photographic film strip 18
The distribution to the branch line 316 is performed via a selector unit 318 provided on the main line 314. Selector section 3
Reference numeral 18 denotes a photographic film strip 18 sequentially sent.
Are sequentially distributed to the main line 314 and the branch line 316 according to the control of the second sub-control unit 310.

On the other hand, as shown in FIG. 14A, the conveyor device 312 has two conveyors (an upstream conveyor 320 and a downstream conveyor 322). The length of the conveyors 320 and 322 is such that the length of the upstream conveyor 320 has a length of (length of the half-size photographic film strip 18 + α), and the length of the upstream conveyor 320 and the length of the downstream conveyor 322 are different. The total length is equal to (the length of the full-size photographic film strip 18 + α).

Then, the second sub control unit 310
If the photographic film strip 18 to be conveyed is a full size, these conveyors 320 and 322 are driven in synchronization with each other, and are rotationally driven as an integrated conveyor.

Specifically, while the conveyors 320 and 322 are both operating at a high speed, the long photographic film 110 is fixed to a certain length (in this case, the length corresponding to the full size) by the conveyor belt 150 and the conveyor device 312. When the start signal Ss is input from the first sub-control unit 180 to the second sub-control unit 310, the conveyance belt 150 is controlled by the second sub-control unit 310. Then, the transport operation of the long photographic film 110 by the conveyor device 312 becomes slow, and then, the required portion of the long photographic film 110 is cut by the film cutter 148 to form the full-size photographic film strip 18.

At this time, the photographic film strip 18 exists from the upstream conveyor 320 to the downstream conveyor 322.

When the cutting of the long photo film 110 is completed, the second sub-control unit 310
Of the full-size photographic filmstrip 18 at high speed by synchronously driving the respective conveyors 320 and 322. By this transport, the next long photographic film 110 is transported to the conveyor device 312 via the transport belt 150.

That is, the conveyors 320 and 322 of the conveyor device 312 are both conveyed at a low speed when cutting the long photographic film 110, and the cutting of the long photographic film 110 is completed and the full-size photographic film strip 18 is cut. At this point, the photographic film strip 18 is controlled to be conveyed at a high speed.

Further, if the photographic film strip 18 to be transported this time is half size, the second sub-controller 310 always controls the downstream conveyor 322 to carry out high-speed transport of the photographic film strip 18, The low-speed transport control and the high-speed transport control of the photographic film strip 18 are performed on the upstream conveyor 320.

More specifically, while the conveyors 320 and 322 are both operating at a high speed, the long photographic film 110 is fixed to a predetermined length (in this case, a half size) by the conveyor belt 150 and the upstream conveyor 320. Length), that is, when the start signal Ss is input from the first sub-control unit 180 to the second sub-control unit 310, the conveyance is controlled by the second sub-control unit 310. The belt 150 stops, and the conveying operation of the long photographic film 110 by the upstream conveyor 320 becomes slow. Then, a required portion of the long photographic film 110 is cut by the film cutter 148, and the half-size photographic film strip 18 is cut. Is done. During this cutting, the downstream conveyor 3
Half-size photo film strip 1 suitable for 22
8 is transported at high speed to the transport line 108 at the subsequent stage.

When the cutting is completed, the upstream conveyor 320 and the downstream conveyor 322 are driven again at a high speed.
Thus, the photo film strip 18 cut this time is transported at high speed to the downstream conveyor 322, and at the same time, the next long photo film 110 is transported at high speed to the upstream conveyor 320 via the transport belt 150. By repeating the series of operations described above, the half-size photographic filmstrips 18 are sequentially conveyed to the conveyance line 108 at the subsequent stage.

Here, as an example of the configuration of the conveyor device 312, for example, as shown in FIG. 14B, when the conveyor path is constituted by one conveyor 324 having a length substantially equal to the length of the full-size photographic film strip 18. (Comparative Example) Although there is no problem in transporting the full-size photo filmstrip 18, the following problems occur when transporting the half-size photo filmstrip 18.

That is, since the half-size photographic film strip 18 has half the length of the full size, while the long photographic film 110 is being cut, the previously cut photographic film strip 18 is located downstream of the conveyor 324. Will be present in the part. Therefore, when cutting is performed by stopping the conveyance by the conveyor 324, the conveyance of the photographic film strip 18 cut last time is also stopped, and the number of processes (throughput) per unit time is reduced accordingly, and the manufacturing efficiency is reduced. Cannot be improved.

On the other hand, in the photographic roll film manufacturing apparatus 100, the conveyor apparatus 312 is divided into an upstream conveyor 320 and a downstream conveyor 322 so that the conveyors 320 and 322 are individually controlled. As a result, while the long photo film 110 is being cut, the photo film strip 18 cut last time can be transferred at a high speed to the subsequent transfer line 108, thereby improving the throughput and the manufacturing efficiency accordingly. Can be planned.

In particular, in this embodiment, the downstream roller 320a of the upstream conveyor 320 is located above the upstream roller 322a of the downstream conveyor 322. Therefore, the half-size photographic film strip 1 existing on the upstream conveyor 320
8 is smoothly conveyed to the downstream conveyor 322 side, and high-speed conveyance of the photographic filmstrip 18 can be easily realized.

As described above, the conveyor device 312 includes:
