Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method and device for winding up a sheet material rolled with a sheet calender, and more specifically to a sheet material such as a rubber sheet rolled with a sheet calender. The present invention relates to a winding method and device capable of automatically and efficiently winding up.

[Prior art]

Conventionally, the work of winding up a sheet material rolled in a sheet calender onto a cell roll placed on a conveyor was carried out by an operator holding the leading end of the sheet material and winding it onto the cell roll.

However, since the sheet material rolled with a sheet calendar is conveyed at high speed by a conveyor, the work of winding it into a cell roll requires skill and timing, and is extremely dangerous work. This also caused wrinkles to occur at the leading edge of the sheet material.

[Purpose of the invention]

This invention was devised by paying attention to such conventional problems, and its purpose is to automatically roll the leading edge of a sheet material rolled with a sheet calendar into a cell roll, thereby solving the conventional problem. To provide a method and device for winding sheet material rolled in a sheet calendar, which improves the work of supplying sheet material to a cell roll, which has been conventionally used, and reduces the occurrence of wrinkles at the leading edge of the sheet material. It is.

[Structure of the invention]

A method of winding a sheet material rolled with a sheet calendar according to the present invention that achieves the above object is a method of winding the sheet material rolled with a sheet calendar onto a cell roll with a liner interposed therebetween, the method comprising: The sheet material is conveyed to a guide roller via a conveyor, and the tip of the sheet material conveyed to this guide roller is connected to a drive roll provided adjacent to the outlet of the guide roller so that it can rotate and move up and down. By introducing the sheet material into the sliding contact portion with the cell roll supported by the cell roll and rotating the driving roll, the tip of the sheet material is rolled into the sliding contact portion and the sheet material is introduced into the cell roll without interposing a liner. The gist is to wind it up.

The apparatus of the present invention is provided with a guide roller that guides the sheet material rolled by the sheet calender at the exit of a conveying gong conveyor disposed adjacent to the exit of the sheet calender, and a guide roller that guides the sheet material rolled by the sheet calender. A drive roll that can be driven to rotate and a cell roll that winds up the sheet material are disposed, and the cell roll is supported so as to be rotatable and up and down, and the liner is configured to be able to be supplied via the drive roll, and The gist is that the roller is in sliding contact with the drive roll.

[Embodiments of the invention]

Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 shows a front view of a winding device for sheet material rolled by a sheet calender according to the present invention. There are two installed with a distance between them.

The winding device 1 has a drive roll 3 driven by a drive motor (not shown) in sliding contact with the drive roll 3 near the tip exit of a guide roller 20 that is installed in the middle of a conveyor 2 and can be raised and lowered. A cell roll 4 that rotates is provided. Note that the outer peripheral surface of this cell roll 4 is similar to that of the drive roll 3.
It is a good idea to apply sandblasting etc. to increase the friction.

Also, a pedestal 5 installed on the conveyor 2
is provided with an arm 7 that can pivot around a fulcrum 6, and a cell roll 4 is rotatably attached to the tip of this arm 7. Furthermore, the arm 7 is attached to a cylinder rod of an elevating cylinder 8 attached to the upper part of the pedestal 5. It is supported so as to be movable up and down via a hinge 12 provided at the tip of 8a.

Further, on the pedestal 5, a winding roll 9 for the liner X interposed between the sheet material W wound around the cell roll 4 is rotatably supported, and 10 indicates a plurality of guide rollers for the liner X.

As shown in FIG. 2, the guide roller 20 disposed at the intermediate exit of the transport conveyor 2 is connected to a drive roller 22 having a plurality of rollers 21 as a pair, and is connected to the drive roller 22. It is composed of a roller 23 that guides the W to the sliding contact portion between the cell roll 4 and the drive roll 3, and by raising and lowering the guide roller 20, the W is rolled by a sheet calender (not shown) and transported by the transport conveyor 2. The winding device 1 is configured so that the sheet material W obtained by the winding process can be alternately supplied to the two winding devices 1.

In the above embodiment, two winding devices 1 are installed on the conveyor 2, but the invention is not limited to this, and if there is sufficient space, multiple winding devices 1 can be installed in series. .

Next, the effect will be explained.

First, before starting the winding operation of the sheet material W, at least one liner X of the winding device 1 is
Pull out the drive roll 3 as shown in Figure 2.
from below, and then wrap the tip of the liner X around the cellulose roll 4 by a certain amount.

When winding the sheet material W around the winding device 1 on the right side of FIG. It is guided by the cell roll 4 and the drive roll 3 and is fed to the sliding contact portion (supply portion). Then, the leading end of the sheet material W is wound into the cell roll 4 which rotates in a fixed winding direction together with the drive roll 3. As the sheet material W is wound onto the cellulose roll 4, the cellulose roll 4 moves upward together with the arm 7 that pivots upward around the fulcrum 6, and performs the work of winding up the sheet material W by a predetermined length. It is something.

When winding of the sheet material W is completed in this manner, the cell roll 4 is slightly lifted from the drive roll 3 by the lifting cylinder 8, and then taken out together with the cell roll 4 by a not-shown carrying-out device.

Further, when winding of the sheet material W on one side of the winding device 1 is completed, the guide roller 20 is lowered to supply the sheet material W to the winding device 1 side on the left side in FIG. Conveyor 2
When the guide roller 20 installed at the outlet is raised, the leading edge of the sheet material W is guided by the guide roller 20 in the same way as described above and is fed to the sliding contact part (supply part) between the cell roll 4 and the drive roll 3. Ru.

Note that the setup of the liner X and the like is performed while the sheet material W is being wound up by the winding device 1 described above.

In addition, in the embodiment described above, the drive roll 3
Gears that mesh with each other may be provided on the cell roll 4 and the cell roll 4, and the cell roll 4 may also be rotationally driven to wind the sheet material W into the sliding contact portion. Moreover, when the winding device 1 is installed at the terminal end of the conveyor 2, it goes without saying that the guide roller 20 does not need to be configured to be able to rise and fall.

〔Effect of the invention〕

As described above, the present invention introduces a sheet material rolled by a sheet calender into the sliding contact portion between a drive roll and a cell roll through a guide roller, and rotates the drive roll to rotate the leading edge of the sheet material. In order to wind it around the sliding contact part and wind it around a cell roll without interposing a liner,
It is possible to efficiently wind up sheet materials such as rubber seeds onto cellulose rolls without manual intervention, eliminate the need for skilled workers, and safely perform the winding work. In addition, since the sheet material can be smoothly rolled into a cellulose roll and wound up without manual intervention while interposing the liner, it is possible to effectively prevent wrinkles and deformation from occurring at the leading edge of the sheet material.
