Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can prevent loosening of a sheet of a wound object by winding and binding a binding tape around a roll of a long sheet and attaching a space between the pressing sheets. The present invention relates to a device for binding a roll.

[0002]

2. Description of the Related Art Conventionally, it has been practiced to wind a long sheet or the like around a winding shaft to form a coil-shaped wound product by using a multi-axis turret type winding and cutting device. After the completion of the winding, the worker attaches an adhesive tape or a binding tape such as a binding band to the winding end of the sheet to bind the sheet to prevent the unwinding of the winding. There is.

However, in such a method, although the winding is automatically performed and the work is rationalized and the labor is saved, the sheet end portion is manually removed by the worker each time the winding is completed. It needs to be prevented from falling apart. Therefore, the work efficiency is low, and the quality of the binding varies depending on the worker. Especially, if the rolled material is strongly pressed, the wound material may be scratched or the traces of the binding may be generated. While the value may be lost, if the presser foot is too loose, unwinding or the like of the wound product may occur, which is not preferable.

In order to solve the above-mentioned problems, the applicant proposed in Japanese Patent Application Laid-Open No. 6-127765 a device capable of automating the work of binding the rolls.

[0005]

However, in the above-described structure, since the roller a for holding the binding tape t and the roller b for sticking are individually present as shown in FIG. 10, the binding tape is present. When t is transferred between the two rollers a and b, the leading end of the binding tape t cannot be reliably delivered and the wound product w cannot be reliably pressed, so that binding failure often occurs. It was

As a result of further research to improve the reliability of operation of the device, the inventor has provided an air hole in the peripheral surface of the roller to which the binding tape is attached, and sucks air on the circumferential side of the binding tape from the air hole. However, it is found that the above-mentioned problem can be solved by forming so that the non-circulating side located on the opposite side can be exhausted, and by having both the holding of the binding tape and the attaching function by one roller. The invention was completed.

According to the present invention, the operation of winding and adhering the binding tape around the winding material to prevent the loosening of the winding material can be automated, and by simplifying the structure and operation, the binding accuracy is improved and the reliability is improved. The purpose of the present invention is to provide a presser structure for a wound material that can improve the winding force.

SUMMARY OF THE INVENTION According to the present invention, a long strip-shaped binding tape is wound around an outer peripheral surface of a winding material in which a long sheet is wound around a winding shaft which can be driven and rotated. A binding device for a wound material, which prevents loosening of a sheet of a wound material by pasting between binding tapes, wherein the supplied binding tape is folded back and circulated, and is parallel to the wound material and on an outer peripheral surface thereof. A movable guide roller that can come into contact with and be separated from each other;
In a state where the guide roller is separated from the outer peripheral surface of the wound body, the guide roller is provided with a cutting tool that cuts the binding tape on the side facing the outer peripheral surface, and a sticking device that attaches the binding tape. , Which has a guide tube that rotates around the central axis and has an air hole that communicates with the inner surface and the outer surface, and has a wrapping portion on the side where the binding tape wraps around the space formed by the central axis and the inner surface of the guide tube, and a non-circulating section. It is a device for binding a wound material, characterized in that the revolving part is divided into negative pressure and the non-revolving part is divided into positive pressure.

The cutting tool has an arm having a blade mounting portion that tilts with the movement of the guide roller, and a knife mounted on the blade mounting portion, and interlocks with the separating movement of the guide roller. The binding tape between the guide roller and the web is preferably formed to cut.

With the above-mentioned structure, the guide roller can be contacted with and separated from the material to be wound, and the wrapping tape circulates in the space between the central axis and the guide cylinder having the air hole. By dividing the space into negative pressure and negative pressure in the circulating portion and positive pressure in the non-circulating portion.

With this arrangement, the bundling tape can be accurately and reliably guided and wound around the outer peripheral surface of the winding material by the contact of the guide roller with the winding material.

Further, the guide roller can be reliably attracted to the outer surface of the bundling tape while it circulates, and can circulate in a stable position. Therefore, it becomes possible to apply the application liquid for application to the binding tape while the guide roller is rotating, and the application accuracy is improved. Moreover, since the guide roller has a positive pressure in the space in the non-revolving part, the binding tape is reliably separated from the guide roller and is pressed toward the outer peripheral surface of the winding material. You can wind it along well.

As described above, since the guide roller can both hold the position of the binding tape and apply the coating liquid for sticking to the binding tape, the guide roller has a roller configuration for operation as compared with the conventional device. This simplifies the operation of the device and makes it easier and more reliable.There is no danger of the feeding tape feeding failure between the rollers unlike the conventional device that requires two rollers, and the winding accuracy of the binding tape is improved. And it can improve the appearance.

Further, when the cutting tool is formed so as to cut the binding tape by interlocking with the separating movement of the guide roller as described above, the structure of the device is simplified, the reliability of the operation is enhanced, and the device is operated. Can be provided more economically.
