Example (b): in the processing process of the commutator, mica sheets and copper sheets are required to be sequentially and circumferentially arranged in a workpiece carrier, and along with the popularization of automatic production, the processing of the commutator can also automatically carry out the processes of inserting and arranging the sheets.

However, in the prior art, a certain problem still exists in the insertion process of mica sheets in a commutator, and before the mica sheets are inserted, a strip-shaped mica strip with the length of about 500mm often enters a station.

But in the inserted sheet engineering, except that the station need set up and cut, mechanism such as liftout, because mica sheet self special material, can have piece or remaining waste material when cutting, before carrying out the inserted sheet process of next commutator, often need manual cooperation to clear up the station, otherwise the piece is long-pending to be left too much, can influence the off-the-shelf quality of commutator.

On the basis, this scheme has proposed a mica sheet arranges piece device, when the mica rod is sent into work holder 11 along pan feeding groove 112 in the middle of, the mica rod can pass through opening 111, cutter 4 can cut the head end of mica rod in entering pan feeding groove 112 this moment, the mica sheet after cutting into the thin slice can be just right directly over opening 111, extrude this mica sheet along opening 111 through ejector pin 21 in the middle of being located the work piece circle core 3 of the opening 111 other end this moment, accomplish after this step, ejector pin 21 resets, and the mica rod can be once more forward the propelling movement wait for the cutting of cutter 4.

After the mica strips are gradually cut, the residual part is not large because the fixing surface is small, the mica strips are easily cut and bent by the cutting knife 4, the quality of mica sheets is affected, so that the residual part of the mica strips is often discarded, new mica strips are continuously fed in, the previous section of the residual mica strips are ejected out of the feeding groove 112 to the outer side of the workpiece clamp 11, and the residual mica strips and waste scraps in the workpiece clamp 11 are synchronously pushed out.
