Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a method for feeding a web to a rotary printing press and an improvement in a web feeder.

(Prior Art) An automatic reel loader A having a structure as shown in FIG. 8 is often used for feeding a web to a rotary printing press. That is, the take-up paper transport trolley B, which has carried the take-up paper Ao from the paper storage, is drawn into the vertically movable frame C of the auto-reel loader A, and then the loader A is driven to reach a predetermined position of the rotary press paper feeding section. The web C is moved and the gantry C is raised to mount the web Ao on the web support device E. More specifically, as shown in FIGS. 9 (a) to 9 (e), the web transporting trolley B is pulled into the gantry C of the auto reel loader A (FIG. 9 (a)), and then the loader A is moved. After the remnant receiving device D mounted on the loader A is positioned below the web supporting device E, the remnant receiving device D is raised and the web remnant F remaining on the supporting device E is lifted.
(FIG. 9B), the loader A is further moved to move the web Ao below the supporting device E, and then the base C of the loader A is raised to mount the web Ao on the supporting device E (see FIG. 9). Thereafter, the remnant core receiving device D is shortened, the remnant core receiving device D is inclined, and the remnant core F is mounted on the revolving paper transport trolley B (FIG. 9D). Finally, the loader A is moved to the initial position. To return the trolley B for transporting the take-up paper drawn into the gantry C to the running rail connected to the paper storage (Japanese Patent Laid-Open Nos. 5232710, 1-197257, 2-70645). etc).

The conventional auto reel loader A is capable of relatively reliably mounting the web Ao carried out of the paper storage by the web transporting trolley B onto the web support device E, and has excellent practical utility.

However, the conventional auto reel loader A still has many problems to be solved.

A first problem is that it is difficult to reduce the size of the auto reel loader A. That is, the conventional auto reel loader A requires both a driving device for traveling of the loader A itself and a driving device for moving the gantry C up and down. There are problems that it is difficult to reduce the cost and speed up the operation, and that a large installation space is required.

The second problem is that the trolley B for transporting the web is an electric trolley of a so-called brush current collecting system, so that the base C of the auto reel loader A is also provided with the same track mechanism and current collecting mechanism as the traveling path of the trolley B. And the structure of the gantry C becomes extremely complicated, and a special loading device is required for loading the web in the paper storage.

(Problems to be Solved by the Invention) The present invention relates to the above-described problem in feeding web paper to a rotary press using a conventional so-called auto reel loader, that is, (a) the size of the auto reel loader increases and the manufacturing cost increases. In addition to the fact that it is not possible to reduce the cost and the large installation space is required, the economics of using the building are lacking. (B) The complexity of the structure of the auto reel loader requires a lot of maintenance and management. It is difficult to operate quickly because the shape is heavy and the power consumption is increased, and (d) it is not possible to easily load the web onto the transport trolley. Yes, by using a newly developed electromagnetic induction type automatic web transporter with lift and traverser in combination, it is possible to reduce the size and weight of the web feeder and speed up the operation. It is an object of the present invention to provide a method for feeding a roll of paper and a roll paper feeder used in the method, which enable extremely efficient automatic feeding of the roll of paper to a turning machine.
