Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a method of feeding a web into a rotary printing press.

(Prior Art) An auto-reel loader A having a structure as shown in FIG. 8 is usually used to feed webs to rotary printing presses.

In other words, the paper roll transport trolley B, which has transported the paper roll AO from the paper warehouse, is placed on the pedestal C that can freely move up and down on the autoreel loader A.
After that, the loader A is driven to move it to a predetermined position in the paper feed section of the rotary press, and the pedestal C is raised to load the web Ao onto the web support WE.

More specifically, as shown in FIGS. 9(A) to 9(E), the trolley B for transporting the web is pulled onto the stand C of the autoreel loader A (FIG. 9A), and then the loader A is moved. The remaining core receiving device installed on loader A is attached to the paper roll support bag ME.
After positioning it below.

The remaining core receiving device is raised to pick up the remaining core F of the web remaining on the supporting device ME (see Figure 9), and the loader A is further moved to move the web Ao below the supporting device IE. After that, the stand C of the loader A is raised to load the paper roll Ao onto the support device E (Fig. 9C), and then the remaining core receiving device fD is shortened and tilted to hold the paper web Ao on the support device E. It is placed on trolley B for transporting web paper (Fig. 9, 2), and finally, loader A is returned to the initial position, and trolley B for transporting web paper, which has been pulled onto pedestal C, is returned to the running rail that connects to the paper storage. Yes (Japanese Unexamined Patent Publication No. 52-3271
No. 0, JP-A No. 1-197257, JP-A No. 2-7064
No. 5, etc.).

The conventional auto-reel loader A can relatively reliably load the web AO carried out from the paper warehouse by the web conveyance trolley B onto the web supporting device E, and has excellent practical utility.

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

The first problem is that it is difficult to downsize the autoreel loader A. In other words, the conventional autoreel loader A requires both a drive device for running the loader A itself and a drive device for lifting and lowering the gantry C, so the autoreel loader A itself has become significantly larger, making it difficult to manufacture. There are problems in that it is difficult to reduce costs and speed up operation, and it requires a large installation space.

The second problem is that since the trolley B for conveying the web is an electric trolley with a so-called brush current collection system, the mount C of the autoreel loader A is also equipped with the same track mechanism and current collection mechanism as the running path of the trolley B. I need it.

As the structure of pedestal C becomes extremely complex.

One disadvantage is that special loading equipment is required for loading the webs in the paper warehouse.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems in feeding paper rolls to a rotary press using a conventional so-called auto-reel loader, namely (a) a complicated structure in addition to a conveyance trolley. (b) The structure of the autoreel loader is complicated; (c) Its large size and weight make it difficult to operate quickly;
The purpose of this project is to solve problems such as increased power consumption and (d) the inability to easily load paper rolls onto transport trolley B, using a newly developed electromagnetic induction type lift-turn. Automatic paper feeding of one roll of paper can be performed extremely efficiently by using an automatic roll paper transport vehicle with a table to directly load the roll of paper Ao transported from one paper warehouse onto the paper roll support device of the rotary press. The present invention provides a paper feeding method for a web.

(Means for Solving the Problems) The present method invention is to move the web Ao stored in the web Ill to the turntable 2 by operating the lift 29 of the electromagnetic induction type lift/turntable equipped web transport vehicle 4.
9b, the paper roll carrier 4 with a lift/turntable is automatically driven along the electromagnetic induction line 5 to the paper feed section 3a of the rotary press 3, and then the carrier 28 of the carrier 4 is moved to the spin turn. At least change the direction of movement to a direction perpendicular to the spindle 25 of the web support bag W4 of the rotary press 3, and rotate the turntable 29b so that the axial direction of the web Ao is parallel to the spindle 25. Then, the roll paper transport vehicle 4 with lift and turntable is moved to position the roll paper Ao placed on the turntable 29b below the web support device E, and the lift 29 of the lift-equipped roll paper transport vehicle 4 moves the roll paper Ao placed on the turntable 29b. The basic structure of the invention is to rotatably support one roll of paper Ao on a roll of paper support device E by raising the roll of paper Ao.

(Function) Position the paper web transport vehicle 4 with lift/turntable below the paper web holding device 16 in the paper [1].

By raising the turntable 29b, the web AO is loaded onto the transport vehicle 4.

The transport vehicle 4 loaded with the paper roll Ao is connected to the electromagnetic induction line 5
The conveyance vehicle 4 travels along the paper feed section 3a of the rotary press 3 that requires paper feeding.Then, the conveyance vehicle 4 spin-turns the conveyance vehicle 28 so that the direction of travel is directed to the web support section of the rotary press 3. ! By turning the lift pedestal 29b in a direction perpendicular to the axis of the support shaft 25 of E,
The axial direction of the web Ao placed thereon is the support shaft 25.
is held in a direction parallel to the axial direction of the After that, it is moved to the web support device ME side of the printing press, and the turntable 29
After the paper web AO on b is held below the support device IE, the lift 29 of the transport vehicle 4 is operated to raise the paper web AO so that its axis coincides with the axis of the support shaft 25. In this state, the support shaft 25 is inserted into the core metal of the web Ao, and thereby the web AO is rotatably mounted on the web support device E.

When the web AO is mounted on the support part wE, the web transport vehicle 4 with a lift turntable is returned to its original predetermined position,
The paper is returned to the paper warehouse l along the electromagnetic induction line 5.
