Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a method for removing a used paper core from a paper web support reel of a rotary press, supplying a new paper core to the reel, and removing it from the reel. This invention relates to an improvement in an auto-reel loader used in automatic roll paper supply equipment that can automatically carry out a series of operations for carrying out a paper core.

(Conventional ridge technique) Conventionally, auto-reel loaders used in automatic roll paper supply equipment include, for example, IJO,! 567384.9
Those disclosed in Publication No. 6 and Japanese Patent Publication No. 60-30622 are known.

That is, the auto reel loader is equipped with a trolley on which a web is placed, and has a trolley elevating mechanism capable of raising and lowering the trolley to supply the web to the reel of a rotary press, and receives a used paper core removed from the reel. It is equipped with a paper core receiver, a filter paper core receiver elevating mechanism that raises and lowers the paper core receiver, and a lifting mechanism that tilts the fly core receiver toward the trolley side, and is laid perpendicular to the axis of the reel of a rotary press. It is configured so that it can run on its own on rails.

When the auto-reel loader pulls in a self-propelled trolley carrying a new roll of paper from the running path near the reel and loads it, the auto-reel loader moves to the reel side, and its paper core holder picks up the used paper. It stops when it reaches just below the core.

Next, as the paper core receiver rises, the paper core is removed from the reel and falls into the paper core receiver, where it is received.

Once the paper core has been removed, the paper roll is raised along with the trolley and loaded onto the reel.

After sowing, the autoreel loader returns to the starting position, and then moves to the trolley side where the paper core holder is now empty.
Transfer the paper core on the paper core receiver to the trolley.

Then, the trolley carrying the paper core is carried out from the auto-reel loader 7 and travels along the running path to transport the paper core to a predetermined position.

In this way, the paper core is removed, the web is attached, and the paper core is transferred.

Therefore, if the auto reel loader is used, each operation can be automated, leading to significant improvements in work efficiency and safety.

(Problems to be Solved by the Invention) By the way, in a rotary press, a plurality of webs are rotatably supported on a web support reel, and when the number of webs that are being drawn out to the rotary press at a constant speed decreases. , the terminal end is glued to the starting end of an adjacent new web to ensure continuous paper feeding, and the thinner web is glued to the new web and then cut by a cutter. ing. Therefore, a portion of the paper (hereinafter referred to as residual paper) remains on the paper core of the thin paper roll, and this residual paper is in a state of unraveling from the paper core.

Therefore, when the paper core is transferred from the reel to a self-propelled trolley using a conventional auto-reel loader, the remaining paper unravels and hangs down from the top of the trolley, blocking the sensor installed on the trolley to prevent rear-end collisions. However, this creates a problem in that it interferes with the running of the trolley.

In particular, if the remaining paper has unraveled from the paper core, it will be extremely difficult to handle when unloading it from the trolley, and when collecting the paper core in one place, it will be collected in a messy manner and the paper will be twisted. Another problem is that the post-treatment of the core cannot be carried out in a good and easy manner.

The present invention was devised in order to eliminate the disadvantages mentioned above, and its purpose is to wrap the remaining paper around a paper core supported by a reel and to fix the end side to the paper core. An object of the present invention is to provide an auto-reel loader capable of transferring the paper core from a reel to a trolley.

(Means for Solving the Problems) In order to achieve the above object, an autoreel loader according to the present invention is equipped with a trolley on which a web is placed, and is moved up and down to transfer the web on the trolley to a rotary press. A trolley lifting mechanism that can feed paper to a reel for supporting the web, and a paper core that is rotatably supported by the reel in the direction in which the remaining paper is rolled up, are provided with a squeezing action, and when the paper core rotates in the direction, the remaining paper is removed from the paper. A filter paper core receiver capable of winding the paper core around the core and receiving the paper core removed from the reel, a fastening device capable of securing the remaining paper wound around the paper core to the paper core, and a filter paper core receiver capable of moving the paper core receiver up and down. It is equipped with a core receiver elevator groove and a lifting mechanism that tilts the paper core receiver toward the trolley side.

(Function) The paper core, which is rotatably supported by the reel of the rotary press in the direction of winding up the remaining paper, is given a squeezing action by the paper core holder, and the remaining paper is rolled up without loosening. When the remaining paper is wrapped around the IJ-ru, the fastening device operates to fasten the remaining paper to the paper core, and then the paper core is removed from the IJ-ru and transferred to the paper core receiver.

When the paper core is delivered to the paper core receiver, the web on the trolley mounted on the auto-reel loader is loaded onto the reel.

When the trolley is empty, the paper core receiver tilts toward the trolley and rises, and the paper core on the paper core receiver is transferred to the trolley.
