Description

[0001] Description [0002] Industrial roller grooving equipment [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to industrial rolls used in production facilities for film, paper, and fiber. More specifically, the present invention relates to a technique for rotating a roll while rotating a roll using a machine tool, This makes it possible to improve the quality of the product because the workability is excellent and the working time is shortened and the machining operation is performed more precisely. In particular, the operator can automatically adjust the angle of the cutting edge according to the specification of the product, So that the work can be carried out quickly and more precisely.

In general, in the production facilities for film, paper, and fiber, a plurality of rolls are used for transporting articles such as films, strips, and sheets according to the manufacturing process. These rolls are made of various materials (FRP), carbon fiber reinforced plastic (CFRP), steel and rubber, for example.

The rolls used in the manufacturing facilities of conventional film fabrics are rotated to transport the film fabric, and this rotation causes the surrounding air layer of the roll to flow along the surface thereof.

The air layer flowing into the roll side of the film transporting facility has a fast moving speed of the film raw material, and the larger the rotation of the roll, the more the inflow amount of the air layer becomes. In addition, the air layer flowing into the roll side greatly reduces the frictional force that must be generated between the rolls and the contact surface between the roll and the roll, and the roll and film fabric slip due to the air thus introduced .

When a slip occurs in a film fabric in a conventional converting facility, a film fabric slitted with a knife by this slip travels to the rear side, and flows in a lateral direction, that is, in a width direction of the fabric, The straightness and the stability are greatly deteriorated.

As a result, the film fabric wound on the winding roll while flowing in the left-right direction is not clean on both sides and is wound unfavorably. This causes the product value of the film fabric to be lowered and the operation efficiency in the subsequent process is lowered, .

Therefore, the final film fabric product wound on the transferring device of the film fabric is the best product that does not disturb both sides of the cross section, and cleanly wound. As a matter of important quality control, in relation to this, improvement of the running stability and straightness of the conventional film fabric Rolls have been proposed. For example, in order to improve the running stability and straightness of a film material such as PET, OPP, CPP, and BOPP, a roll having a radial straight groove or a radial spiral groove formed on its surface has been proposed.

As described above, the rolls processed with the radial straight grooves or the radial spiral grooves are formed by several or several tens of grooves machined at regular intervals in consideration of the pitch. By guiding and removing the air layer between the grooves, The frictional force between the roll and the film material is maintained, and slip is prevented.

Therefore, a universal machine tool such as a lathe is used as a method for machining a radial runner groove or a radial spiral groove on the surface of a conventional roll, and this method involves chucking a roll on a machine tool, A groove is formed on the surface of the roll using the cutting edge.

Such a conventional method has a problem in that precision is lowered as the worker carries out the work process by hand, the work time is lengthened, work efficiency and productivity are lowered, and the angle or pitch of the groove can not be precisely processed according to the specification of the product, There are problems that can not be coped with.

Korean Patent No. 10-0992493. Korean Patent No. 10-1064646. Korean Patent No. 10-1286174. Korean Patent No. 10-1335287.

In the prior art of the conventional industrial roll, when a straight groove or a spiral groove is machined on the surface of a roll, precision and productivity are deteriorated while the precision and accuracy of the groove are reduced. In order to solve the problems that can not be solved, a technique has been proposed in which the cutting edge is rotated and moved while rotating the roll using a machine tool to form grooves on the surface of the roll, and the angle of the cutting edge is selectively And an object of the present invention is to provide a groove processing apparatus for an industrial roll in which a machining operation is performed automatically.
