1,012,722. Packaging-machines. ROSE BROS. (GAINSBOROUGH) Ltd. June 12, 1962 [June 19, 1961], No. 21975/61. Heading B8C. Wrapped sweets 11 are delivered on a conveyer 12 from a wrapping machine for transfer in batches into trays 23, each tray receiving one or more layers of sweets at a transfer station 15, and the filled trays are removed for wrapping in paper, film, or foil. As the sweets are fed on to a plate 14, Fig. 3, the leading sweet operates a feeler 68 causing a pusher 72 to move them to a waiting tray, any sweets out of position being fed in by plungers 86 on a carrier 85. Collapsed trays 23 are removed singly from a magazine 28 by a cam-operated pusher 29 to feed rollers 38, 39, Fig. 2, which forward the trays to a forming station 42 where a plunger 52 pushes them through a die aperture 51 in a plate 41 and into a waiting pocket 22 of an intermittently movable chain conveyer 18. The opened tray is moved first to an idler station before it reaches the sweet transfer station 15. The pocket carrying the tray is tilted by means of a member 62 so that one edge of the tray lies under the level at which the sweets are supplied. The roller 26 on which one side of the pocket 22 is supported leaves a guide track 27 to enter the member 62 which is cam-operated to pivot the pocket on its support 24 at the other side, enabling the sweets 11 to be pushed in. At each operation the pusher 72 moves a pawl-and-ratchet mechanism 99, 101 causing the intermittent rotation of the driving shaft 21 of the conveyer 18. After transfer of two batches of sweets by the pusher 72, the pocket 22 is lowered and the conveyer 18 removes the filled tray which is then raised by a reciprocating member for lateral transfer by a cam-operated pusher to a receiving platform (Fig. 4, not shown).
