2. Description of the Related Art Generally, a crown capping machine is provided with a plurality of capping heads which are provided on a rotating body and rotate integrally with each other, and a bottle base, which are aligned in a certain direction by a crown sorter and are dropped and supplied by a chute. The caps thus taken out are taken out by a crown take-out device and delivered one by one to the respective capping heads, and the capping heads are moved up and down with respect to the bottles on the bottle base to cap them.

As the above-mentioned crown take-out device, for example, the one shown in Japanese Utility Model Publication No. 61-31995 has been conventionally known. This crown take-out device (crown feeder) is a cycloid gear 11 rotatably held by a support 10.
And a crown star wheel 12 which is integrated with the cycloid gear 11, a crown receiving slide 13, and magnets 14 and 40 which are integrally held below the crown sliding surface of the crown receiving slide 13. The crown 8 aligned in the same direction by the crown aligning device and dropped and supplied by the chute 7 is housed in the pocket 12b of the star wheel 12 while being attracted by the magnets 14 and 40. The crown star wheel 12 holds and rotates the crown 8 and conveys the crown 8 to the lower part of the stoppering plunger 3. The stopper plunger 3 is lowered by the cam 6, and the crown 8 is attracted and held by the magnet 31 embedded in the stopper head 30. After that, the stopper plunger 3 further descends to stopper the top of the bottle.

In the above-mentioned conventional crown extracting device, magnets 14 and 40 for guiding the crown 8 into the pocket 12b of the crown star wheel 12 support the lower surface of the crown 8 and guide it. Since it is installed in the slide 13, the crown star wheel 12 has a crown 8
When gripping and transporting, the crown receiving slide 13 and the crown 8 attracted to the crown receiving slide 13 may cause friction, and the skirt portion (peripheral fold portion) of the crown 8 may be damaged. There was a problem. Further, the crown 8 and the chute 7 which are rotationally conveyed by the crown star wheel 12.
Since the subsequent crowns 8 in it are at the same height, the outer peripheral folds of both crowns 8 may mesh with each other. Further, since the lower surface side of the crown 8 is an open space except for the folds on the outer periphery, there is a problem that the attractive force of the magnets 14 and 40 does not act sufficiently.

The present invention has been made to eliminate the above-mentioned drawbacks, and the attraction force of the magnet for attracting the crown dropped by the chute into the crown ejecting device can be strongly applied to the crown. Moreover, when the crown taken out from the chute is rotationally moved to be delivered to the stoppering head, friction with the lower support plate does not occur, and there is no fear that the crowns will mesh with each other. It is intended to provide.
