[Problems to be solved by the device]

 The former stencil feeder supplies the roll stencil supported by the support arm of one rotating shaft to the corrugating machine through a splicer installed above the stencil, and the supporting arm of the other rotating shaft. The front end of another roll base paper, which was previously supported and placed on the paper, is connected by a splicer to the base paper being supplied, and the base paper is continuously supplied to the corrugating machine. It takes a long time to replace the roll base paper because it has to be moved to the upper position, transported to a predetermined place, emptied from the transport rail, and loaded with a new roll base paper. As a result, the corrugated machine production line has become faster, and the current corrugating machine, which frequently changes orders such as paper quality and paper width due to low-lot production, cannot be supported. Is decreasing.

The latter base paper hanging machine uses one of the three transport conveyors for unloading, and while transferring the used roll base paper, carries the next roll base paper into the empty transport conveyor, Although it is possible to shorten the time required to replace the roll base paper by reversing the rotation axis and immediately holding this roll base paper in standby, a lifter for raising and lowering the roll base paper is used for each conveyor. Therefore, there are drawbacks that the manufacturing cost is high and there is a danger in operating the lifter.

An object of the present invention is to provide, at a low cost, a base paper hanging machine that allows roll base papers to be replaced in a short time, and that the roll base papers can be safely unloaded.

[0007]

[Means for Solving the Problems]

 In the base paper hanging machine of the present invention, a central conveying rail for roll base paper and both left and right conveying rails are installed side by side on the floor, and a pair of front and rear lateral moving devices are arranged between the respective conveying rails. It is characterized by supporting the front and rear ends of both left and right rotating shafts on bearings provided in the lateral movement device, and supporting arms with core chucks that rotatably hold the roll base paper are attached to these rotating shafts.

[0008]

[Action]

 For example, as shown in FIG. 5 (a), the roll base paper 15 carried along the left transport rail 1 to the outside of the rotary shaft 12 is rotatably supported by the support arm 16 of the left rotary shaft 12. And is supplied to the corrugating machine through a known splicer (not shown) installed above it. When the order is changed or when the left roll base paper 15 reaches the end, the right roll base paper 15 which has been previously loaded by the right transport rail 1 and rotatably supported by the support arm 16 is on standby. The leading end is connected to the left roll base paper 15 by a splicer and continuously supplied to the corrugated machine.

The left roll base paper 15, which has been cut by the splicer and has a small diameter, is transferred onto the central transport rail 1 by the inward rotation of the rotary shaft 12 as shown in FIG. 5B. However, when the rotary shaft 12 is moved to the left in accordance with the diameter of the roll base paper 15, the center of the core chuck 18, that is, the center of the roll base paper 15 coincides with the center line L of the central transport rail 1. Therefore, the roll base papers 15 having different diameters can be accurately placed on the transport rail 1 and discharged.

As shown in FIG. 5 (c), a new roll base paper 15 is immediately loaded into the empty left transport rail 1, and the rotary shaft 12 is rotated outward according to the diameter of the roll base paper 15. When moving and moving rightward, the center of the core chuck 18 coincides with the center of the roll base paper 15, that is, the center line L of the transport rail 1, so that the roll base paper 15 having different diameters is supported by the support arm 16. Therefore, it is possible to accurately hold it and deal with paper splicing due to the next order change.

In the state shown in FIG. 5C, when the right roll base paper 15 reaches the end or when the order is changed, the tip of the left roll base paper 15 is connected to the right roll lug 15 by a splicer. Then, the above steps are repeated.

Although the left and right transport rails 1 are used to carry in the roll base paper 15 and the center transport rail 1 is used to carry out the roll base paper 15, the center transport rail 1 is used for carrying in the left and right roll rails 15. The transport rail 1 may be used for unloading.

[Effect]

 In the base paper hanging machine of the present invention, the central and left and right transport rails are arranged side by side, and the left and right rotating shafts provided with the support arms are arranged between them so that the used roll base paper can be carried in. Since it is configured so that the new roll base paper can be loaded into the carry-in transport rail immediately after being moved from the transport rail of the above, the time required for replacing the roll base paper can be shortened, and therefore, the cardboard It can be fully adapted to the current corrugated machine, where the production line has become faster and the order changes due to low-lot production have become more frequent.

When the roll base paper is unloaded, the rotation shaft is moved to the left and right by the lateral movement device, so that the center of the core chuck of the support arm is aligned with the center line of the transport rail to rotate the support arm. As a result, it is possible to accurately hold the roll base paper with different winding diameters by the core chuck and to place it accurately on the tray on the transport rail.

The base paper hanging machine of the present invention can be manufactured at a low cost because the structure for aligning the center of the core chuck with the center line of the transport rail is simple when the roll base paper is unhooked. .
