Description

A tape transport device and a tape transport method

Technical Field

The present invention relates to the technical field of automated production equipment, and in particular to a tape transport device and a tape transport method.

Background technique

The strip is usually wound on a slit roll. When processing the strip, the strip on the slit roll is usually made to pass through multiple processing stations before being wound up by a reel. The strip has two sides. For easy distinction, we call one side of the strip side A and the other side of the strip side B. The existing tape transport device and the well-arranged tape transport structure cannot be used to process the other side of the strip when processing the A side or the B side of the strip is required. Taking the coating cleaning line as an example, after the coating process, the processed surface needs to be cleaned. The existing tape transport device of the coating cleaning machine can only meet the cleaning of one coated side. When both coated sides are processed, the tape transport device of the coating cleaning machine cannot be compatible with the cleaning of the A side and the B side of the coating.

According to one embodiment of the present invention, the transition roller group includes a feed transition roller and a discharge transition roller, the feed transition roller is arranged close to the execution roller group, and the discharge transition roller is arranged close to the main drive roller group, and the strip material coil output by the execution roller group successively bypasses the feed transition roller and the discharge transition roller and then conveys the strip material to the main drive roller group (1).

According to one embodiment of the present invention, the transition roller group further includes a plurality of tension rollers, and the plurality of tension rollers are arranged between the feed transition roller and the discharge transition roller along the direction of the strip coil.

According to one embodiment of the present invention, it also includes a buffer mechanism, which is arranged at the output end of the main drive roller group. The strip material output by the main drive roller group is buffered by the buffer mechanism before being output.

A tape running method, using the above tape running device, comprises the following steps:
