The roll holder 56 has, for example, six chuck claws 56a that can be inserted into the paper tube PP of the film roll R, and opens and closes the six chuck claws 56a inserted into the paper tube PP of the film roll R. This makes it possible to clamp and unclamp the paper tube PP of the film roll R.

Therefore, after moving the roll holder 56 to the roll take-out position P4 and inserting the chuck claw 56a of the roll holder 56 into the paper tube PP of the film roll R suspended from the roll support member 36, When the roll holder 56 is moved in a direction away from the roll support member 36 while the pipe PP is clamped, the film roll R suspended from the roll support member 36 can be taken out. Note that when inserting the chuck claw 56a of the roll holder 56 into the paper tube PP of the film roll R suspended from the roll support member 36, the chuck claw 56a is inserted between the four support rods 37b. The positional relationship between the two is set.

A reflecting mirror (not shown) that reflects the light emitted from the light emitting part of the roll detection sensor 58 toward the light receiving part of the roll detection sensor 58 is attached to the outer surface side. As a result, when the chuck claw 56a is inserted into the paper tube PP of the film roll R suspended from the roll support member 36 at the roll take-out position P4, the light emitted from the light emitting part of the roll detection sensor 58 is received. When the light is no longer received by the film roll R, it is detected that one end surface of the film roll R is located at that detection position.

Then, based on the position of one end surface of the film roll R detected in this way and the paper core width data of the film roll R inputted in advance by the operator, the position of the other end surface of the film roll R is determined. By calculating the position, the hanging position of the film roll R suspended from the roll support member 36 is grasped, and the chuck that has entered the paper tube PP of the film roll R is determined according to this hanging position. By adjusting the stop position of the claw 56a, the chuck claw 56a is always inserted into the film roll R by a predetermined amount.

Further, when the roll holder 56 clamps the paper tube PP of the film roll R suspended on the roll support member 36, the rotating disk 35 of the roll stock device 32 described above rotates slightly, and accordingly, the roll Since the four support rods 37b of the roll support member 36 located at the take-out position P4 are slightly lowered, the support rods 37b of the roll support member 36 that was suspending the film roll R at the roll take-out position P4 are It is spaced apart from the inner peripheral surface of the paper tube PP of the film roll R.

They are connected by pasting the T, thereby completing the joining of the band-shaped films F to each other. In this state, the drive of the film delivery roller 72 (see FIG. 7) is restarted, and delivery of the strip-shaped film F to the accumulation unit 75 is restarted.

As described above, according to the film delivery device 30 of the present embodiment, the film roll R supplied to the roll stock position SP with the starting end F1 fixed to the roll outer peripheral surface with the adhesive tape T is transferred to the film delivery station. 40, the terminal end F2 of the already fed film strip F and the starting end F1 of the film strip F of the newly supplied film roll R can be spliced together, and the film feeding operation can be resumed. Therefore, according to the film feeding device 30, automatic operation with reduced manpower or unmanned operation is possible.

Note that the present invention is not limited to the above-described embodiments and modifications thereof, and various changes and improvements can be made within the scope of the claims of the present application.

Although the example in which the film roll R is supplied to one film delivery device 30 by one film roll supply system 10 has been described above, the present invention is not limited to this. For example, like a film delivery system 100A shown in FIG. 22, one film roll supply system 10 may supply the film roll R to two film delivery devices 30a and 30b. In this case, in addition to the transport device 14a that supplies the film roll R to the film delivery devices 30a and 30b, for example, an articulated arm robot transports the packaging box 1 to the storage location 15 and transports the inner bag 5 to the input location 19. A transport device 14b consisting of the following may be installed.

Furthermore, in the above description, an example has been described in which the packaging box 1 is unpacked and the film roll R containing the inner bag is taken out, and then the film roll R is taken out from the inner bag 5 and supplied to the film feeding device 30. It is not limited. For example, as shown in FIG. 23, the conveyance device 14 is configured to take out a plurality of film rolls R stacked on the pallet 6 in an unpacked state one by one, and convey and set them at the roll stock position SP. You can also use it as In this case, as shown in FIGS. 24(a) and 24(b), it is preferable to interpose a flexible sheet material 7 between the film rolls R stacked on the pallet 6. Thereby, damage to the film due to direct contact between the end surfaces of the film rolls R stacked one above the other can be prevented or suppressed. In this way, the transport device 14 not only supplies the film rolls R packed in the packaging box 1, but also supplies the unwrapped film rolls R stacked on the pallet 6, thereby creating a film roll supply system. 10's versatility is improved. Further, in this case, a packaging box, an inner bag, etc. for packaging the film roll R are not required, so resource saving can be achieved. In addition, when a plurality of film rolls R are delivered to a factory in a state in which they are stacked on a pallet 6, the plurality of film rolls R may be wrapped with a band-shaped wrap material made of synthetic resin wrapped around them. Alternatively, the packaging may be covered with an outer bag made of synthetic resin, but in such cases, the outer packaging such as the band-shaped wrap material or the outer bag may be removed manually, by the conveying device 14, or by another device. Preferably, it is unpacked and fed to the film roll supply system 10 by an unpacking device.

In addition, in the above, the strip film F is obtained from a film roll R in which a long strip film F, which is folded into a sheet shape with cylindrical labels continuously connected, is wound around a paper tube PP. Although the description has been given of a film feeding device that feeds out a film to a labeling device, the present invention is not limited thereto, and the present invention can be applied to various film feeding devices that feed out a simple strip-shaped film from a film roll.

Furthermore, in the above, a case has been described in which a film roll R in which a long strip-shaped film F is wound around a paper tube PP is used, but the present invention is not limited to this, and a film roll without a paper tube is used. The present invention can also be applied to the case where .
