Title: Improvements in wrapping machines
IPC: B65B35/46
Filed: 1953-08-04
Abstract: 728,111. Wrapping-machines. FORGROVE MACHINERY CO., Ltd., and BROOK, L. Nov. 25, 1953 [Aug. 4, 1953], No. 21506/53. Class 94 (1). [Also in Group XXX] Relates to wrapping-machines of the type comprising an intermittently-rotating horizontal feed disc 19 having circumferentiallyspaced pockets 20, which convey sweets and like tablets from a loading station where they are deposited on the disc to a lifting station where a device, such as a plunger 24, lifts them in succession from the pockets into wrapping mechanism, fixed walls 22, 23 and 123 extending across and around the disc to define a tablet-receiving tray and a rotary brush 25 which prevents tablets not retained in the pockets from passing out of the tray to the lifting station. In order to break up accumulations of tablets, an arm 48 is mounted within the tray on a pivot 47 located at or near the centre of the disc and is oscillated across the surface of the disc, preferably once per machine cycle. As shown, tablets are lifted from a bowl 10 by a vibrating elevator 11 comprising a vertical'tube 12 surrounded by a spiral ramp 13 and are discharged from a platform 14 down a pivoted chute 16 on to the disc 19 which is rotated intermittently in a counter-clockwise direction over a fixed annular supporting plate 21. The latter is formed with an aperture 31 to allow passage of the plunger 24 which lifts each tablet together with a wrapper 29 into a pocket 30 of a twist-wrapping wheel 28. The brush 25 is disposed in a gap in the wall 23 and is driven in opposition to the disc by an electric motor 26. The arm 48 is constituted by a thin steel blade presented edgewise to the disc and may extend only from the point X to the point Y. As shown, however, it is extended at 53 to form a member of oval shape which is oscillated through angle B by a link 49 operated by an eccentric 51 to scatter the tablets outwardly in the directions indicated by arrows D and E as they are thrown back in the direction of arrows C by the brush 25. The elevator 11 normally feeds tablets to the disc at a rate greater than their rate of removal by the plunger 24. As the tablets accumulate, they lift a pivoted trip arm 32 which, as described in Specification 728,097 operates a micro switch in a casing 41 to de-energize a solenoid 42, the armature of which is coupled by linkage 43-45 to the shoot 16 thereby allowing a spring 46 to swing the shoot to the broken-line position in which it returns the tablets to the bowl 10. When the accumulation has been cleared, the the arm 32 drops and the solenoid is energized to return the shoot to its normal position.
