Abstract

674,189. Machines for moulding tablets, drops &c. SANDALL PRECISION CO., Ltd., and BARKER, A. W. Nov. 15, 1950 [Nov, 16, 1949], No. 29386/49. Class 87 (ii) A strip of plastic material is fed in a direction A, Fig. 1, and severed by a wheel 14, Fig. 3, into pieces, which fall into grooves 13 between rings 4, 5 of a rotary die 3. A die 20 is moved inwardly by a cam surface 23 on a fixed ring 25 to press a cut piece against an ejector die 33 which is also moved inwardly by a cam surface 35 to press the piece towards the end of the movement of the die 20. Either the die 20 or the die 33 or both are vibrated at the commencement of or during the withdrawal of the dies to facilitate the removal of the moulded piece from the dies. As shown in Fig. 3, the dies 20 are positively withdrawn by a cam surface 45 which engages a projection 39 adjustably mounted on the die. Part of the cam surface is made of saw-toothed or sinuous form, Fig. 4 (not shown), to vibrate the dies 20. In a modification, Fig. 7 (not shown), a similar cam is provided to withdraw and vibrate the ejecter dies 33. Springs 42, 37 are provided to keep the dies in engagement with the cam surfaces and the springs 42 may also return the dies 33. The cam rings 25, 45 are mounted on fixed horizontal posts 28, 29, Fig. 1. They may be adjusted axially along the posts, and the posts may be mounted to allow the cams to be adjusted about the axis of the rings 4, 5. A part of the cam. 45 may be arranged to be swung down on release of a locking member, for cleaning of the cam or inspection of the lower part. of the rotary die.
