[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can winding part cutting device for cutting a can winding part of a beverage such as beer to inspect the can winding part.

[0002]

2. Description of the Related Art As a process control and a quality control in a can winding process, a can C that has been wound is randomly sampled from a line after the winding process, and is usually marked in advance as shown in FIG. It is cut into three narrow strips P at 120 ° intervals, the strips P are enlarged by a projector, the dimensions of the shape are measured, and the winding state is inspected.

For this reason, conventionally, for this reason, the winding portion of the can winding portion of the can winding portion, in which the parting blade is arranged between the two rotating blades arranged at a slight distance, is pressed against the rotating blade of the winding portion of the can C. Then, the can C is manually rotated by 120 ° to cut the narrow strips P at three places.

Since the narrow strip P for inspection is collected as described above, (1) it is difficult to obtain the narrow strip P having the cutting length required for inspection, and (2) it is also accurate. It is difficult to position the cans C at intervals of 120 °, and (3) in the case of the cans C having a shorter length, the cans C can be manually cut during cutting work.
Is difficult to operate and position,
Furthermore, (4) Due to such a problem, there is a problem that the rotary blade is damaged during cutting or an accident occurs.
