When activated, the molded caps C slide down the chute 14 one by one, are received by the screw 61 and sent forward. The caps C that have been fed to the front end of the screw 61 are fed into the magazine 12 through the cap intake port 21 and are accumulated in the vicinity, but as the accumulation progresses, they are pushed by the caps C and become weighted. 27 sequentially move forward. When the caps C are accumulated near the front end of the feed rod 91, the proximity switch 102 detects this and the feed rod 91 is activated, causing the caps C at the rear of the magazine 12 to be fed toward the front. It will be done.

When the magazine 12 becomes full, the operation of the cap forming device 11 is temporarily stopped, the full magazine 12 is replaced with another empty magazine 12, and the cap forming device 11 is started again.

Effects of the invention According to this invention, the caps formed by the cap molding device slide down the chute, are received by the first cap feeding device, and are fed directly into the magazine, so that the caps can be placed in the magazine without requiring any human intervention. Caps can be stored automatically, and since the caps do not change their posture during storage, the caps can be aligned and stored in a predetermined posture.

Furthermore, since the caps at the rear of the magazine are fed toward the front by the second cap feeding member, excessive force is not applied to the caps when accumulating them in the magazine. is not deformed.
