Abstract

PURPOSE:To reduce edge sounds at the time of cutting by constituting a die cutter in such a way that a wave is cut by adding a cutting/breaking force and a crushing force by the differential movement between respective cutting edges. CONSTITUTION:In a die cutter device, at the beginning of cutting, the cutting of a wave 17 is started in such a state that the cutting edge Al on the side A is turned precedently to the cutting edge B1 on the side B, and in the position where the respective cutting edge parts are most adjacent, the cutting edge A2 on the side A is opposite to the cutting edge B2 on the side B. When the device is further turned, the respective cutting edges A, B move differentially, and the cutting edge B3 on the side B is brought into such a condition that it is precedent to the cutting edge A3 on the side A, and a cutting force, breaking force, crushing force or the like are caused in the cutting part of the wave 17. Thus, while differentally moving the respective cutting edges, the wave 17 is cut without causing edge sounds.

2. Description of the Related Art A die cutter roll device is one of cylindrical rolls arranged opposite to each other, and the die cutter roll forms a blade shape of a predetermined shape with a protrusion on the outer periphery, and the other roll, The anvil roll is a device that has a flat outer peripheral cylindrical shape, is arranged so that there is no unnecessary gap between both rolls, and is configured to rotate the other roll in the opposite direction to the one rotation direction. , Is to cut into a protruding blade shape of the wave by continuously supplying a band-shaped wave between the rolls of the apparatus, but a strong cutting force is required because the cutting method is a pressing method. In addition, the blade part of the protruding blade may be in a position where it is cut in the lateral direction, and the blade tip part is in contact with the metal due to the strong pressing force, so the sharpness deteriorates and wear of the blade tip part is unnecessary between rolls. Gap was also caused. In order to improve the sharpness and to restore the gap between the rolls to the normal state, it was necessary to regenerate the blade edge portion of the protruding blade and polish the roll surface on the opposite side. The shape of the protruding blade shape of the die cutter roll is in the direction of cutting in the lateral direction as opposed to the rotation direction, which requires a cutting pressing force applied to the cutting edge at the time of cutting, but the conventional die cutter roll is a roll The surfaces are arranged facing each other, which have been polished by parallelism and cylindricity with a constant pressing force irrespective of the blade shape.Therefore, the pressing force is applied to the part where the cutting pressing force is insufficient due to the wear of the cutting edge. The force could not be increased and as a result regenerative polishing had to be done.

[Means for Solving the Problems] The applicant has conducted various tests in order to solve such a problem. As a result, the applicant has succeeded in determining that the die cutters, which are arranged relative to each other, have an arbitrary shape. The die cutter tool device, which has the blade shape of No. 3 and is formed on the outer peripheral surface, is relatively named as a die cutter device.

In the die cutter device of the present invention, cutting of an arbitrary shape is continuously used at a high speed for a long period of time, and the cutting surface is complete and highly accurate, and the pressing force, which is a marked difference from the conventional product, is small. A means for providing a force-cuttable device is described.

One of the die cutters arranged relative to each other is provided with a die cutter A having a blade shape of a predetermined shape on its outer peripheral surface, and the die cutter A is arranged so as to face the die cutter A so as to rotate synchronously. Each of the cutting edges is formed on the outer peripheral surface with a blade shape having the above-described predetermined shape that is opposed to the die cutter A, and the diameters of the blade shapes are not the same for each die cutter AB but are different for each blade. Since it is a die cutter device characterized by being configured to rotate synchronously while differentially rotating,

At the cutting start portion, the A-side cutting edge rotates in advance of the B-side cutting edge to start cutting the wave. When each cutting edge portion is at the closest position (opposing position), each cutting edge is cut. Both the A side and the B side face each other, and further rotation causes a differential between the respective cutting edges AB, so that the B side cutting edge precedes the A side cutting edge, and the cutting force, the breaking force, and the crushing force at the cutting portion of the wave. It is configured so as to cause such as the above, and is configured so that it can be cut while making a differential between the cutting edges.
