After the holder 25 has stopped at the positioning layer of the receiving rails 23, 23, the holder 39 is moved forward by the operation of the cylinder 46, and the holding part 38 is positioned on the receiving rails 23, 23 immediately behind the holding part 24 of the holder 25. . After that, the holder 25 is moved backward by the actuation of the cylinder 34, and by the actuation of the cylinder 37, it stands by in the normal position facing the original receiving rails 21, 21, and the next can lid cylinder 6 is moved back to the lower roller 13 as described above.
, 13, it moves forward again to hold both ends of the can lid cylinder 6. Further, the can lid 3 whose rear portion is held by the holding part 38 of the holder 39 is transferred to a tightening device (not shown) by the force of the weight by releasing the operation of the cylinder 49, and after being transferred, the holder 39 is returned to its original position by the operation of the cylinder 49. Wait in the correct position on the receiving rails 23, 23. The can lids from which the wrapping paper 5 has been opened and removed as described above are smoothly transferred from the unsealing section to the tightening device by the holders 25 and 39 while maintaining the packaged and aligned state.

Incidentally, the actuation timing of each of the above-mentioned members is determined using a known detection member such as a proximity switch or a phototube.

Since this invention is configured as described above, both ends of a plurality of can lids supported sideways in a cylindrical manner by a pair of guiding sections provided at the first station are moved forward and backward of the first holder. Can lids held in this way can be held securely by a pair of holding parts, and the can lids held in this way can be aligned from the guide member of the first station onto the guide member of the second station without shifting by the forward movement of the first holder. and can be transported,
Further, at the second station, the rear end portion of the can lid transferred by the first holder as described above can be reliably held by moving the holding portion of the second holder forward.
After the pair of holding parts of the first holder move back out of the second station, the can lid held in this way can be further transferred by the forward movement of the second holder.
