  2. Description of the Related Art Conventionally, in newspaper companies and the like, a newspaper web automatic guided vehicle is generally used to supply new newspaper webs to a rotary press or collect newspaper webs in use. Newspaper webs are commonly used that have a length of 1626 mm, called volume A, a length of 1219 mm, called volume C, and a length of 813 mm, called volume D.

  FIG. 8 is a schematic side view showing a state in which a conventionally used newspaper web unmanned conveyance vehicle (hereinafter referred to as “automated conveyance vehicle”) mounts an unused volume D newspaper web R2 on a rotary press. It is. The automatic guided vehicle 200 guides the newspaper web between the storage place and the place where the rotary press is installed by, for example, electromagnetic waves generated by electromagnetic induction wires laid on the traveling road surface F, magnetic flux generated by the magnetic tape, or reflective tape. A traveling mechanism 220 for unattended conveyance and a lifting unit 240 attached to the traveling mechanism 220 for vertically moving the newspaper web R2 in the vertical direction are provided.

  The elevating unit 240 has elevating means 243 having an elevating table 241 and an inner arm 243a and an outer arm 243b called an X-shaped panter arm that drives the elevating table 241 to elevate. Further, two linear guides 244 are formed in parallel on the upper surface of the lifting table 241, and a moving table 245 that slides across the linear guide 244 is installed.

  The automatic guided vehicle 200 in which the newspaper web R2 is mounted on the moving table 245 at the storage location of the newspaper web is composed of a fixed-side web holding arm A and a moving-side web holding arm B that are provided opposite to the paper feeding device of the rotary press. Enter downward. The center axis C1 of the roll C of the newspaper web R2 is the center axis of the fixed side cone A1 mounted on the fixed side web holding arm A and the moving side cone B1 mounted on the moving side web holding arm B. The elevating unit 240 raises the newspaper web R2 on the moving table 245 so that the center axis D connecting the center axis coincides with the center axis D. Then, the moving side web holding arm B is moved horizontally in the direction of the fixed side web holding arm A, and the moving side cone B1 is fitted to one open end C2 of the roll C of the newspaper web R2. Further, when the moving side web holding arm B is moved in the direction of the fixed side web holding arm A, the moving table 245 carrying the newspaper web R2 slides on the linear guide 244 of the lifting table 241 so that the newspaper web R2 is fixed on the fixed side. The fixed-side cone A1 of the web holding arm A and the other open end C3 of the winding core C are fitted, and the installation of the newspaper web R2 to the paper feeder of the rotary press is completed. As described above, when the radius of the newspaper web R2 is larger than the radius of the moving side web holding arm B, the newspaper web can be used with respect to the rotary press without any trouble regardless of whether the web is A, C, or D. Can be installed and collected.

FIG. 9 is a schematic side view showing a state in which the same automatic guided vehicle 200 as shown in FIG. 8 described above collects the A-roll newsprint R3 in use from the rotary press. Since the length in the axial direction of the A roll is sufficiently longer than the lifting table 241, the automatic guided vehicle 200 uses the fixed-side web holding arm A and the moving-side web holding arm B of the rotary press holding the newspaper web R3. You can enter below. Then, the moving-side winding paper holding arm B is moved back away from the fixed-side winding paper holding arm A, so that the newspaper winding paper R3 is released from the clamping between the fixed-side winding paper holding arm A and the moving-side winding paper holding arm B. . Then, the lifting table 241 is lowered, and is unmannedly conveyed by the traveling mechanism 220 to the storage location of the newspaper web.
