Title: Improvements in or relating to packing machinery
IPC: B65B19/18
Filed: 1928-02-18
Abstract: 312,109. Molins, W. E. Feb. 18, 1928. Packeting cigarettes &c.-Cigarettes or like articles are automatically inserted in a carton of the slide and shell type, and the carton is thereafter moved into engagement with a strip of wrapping material which is automatically wrapped about the carton. The operation of the wrapping mechanism is controlled by the supply of filled cartons, and vice versa. As shown, a batch of cigarettes is removed from a hopper 1, Fig. 1, by a continuously moving conveyer, and carried between guides 2 past apparatus 3 for applying foil. According to the second Provisional Specification the hopper apparatus may be as described in Specification 216,326. A feed apparatus 6 feeds slides 7 at a. lowar level between guides 8 to position 9, where the cigarettes are introduced on to the is forced through a mouthpiece, 11 into a shell up in any suitable manner, and the charged slide tray. The sides and ends of the shell are folded disposed to receive it. The Riled and closed carton is next carried into contact with a web of thin transparent paper fed from a reel 13, which is folded about the carton to form a U- shaped block ended packet. Gum is applied at 14 and the ends closed at 15 before the packets are fed into a vertical stacker 16. In modified forms, the conveyers which move the packets from one mechanism to another may be at right angles, or offset, and transference from one conveyer to another may be effected by a plunger. The shells may be pushed on to the slides as described in Specification 169,341. According to the first Provisional Specification the wrapping mechanism may be as described in Specification 259,094. In the form shown in Fig. 3, the packets are pushed from the filling and closing apparatus on to a fixed plate 30 and moved by an oscillating plunger 31 on to a belt 29. A heavy roller 32 presses them on to the belt and a cam operated presser 35 ensures that the foremost packet is pressed into the guides 34 of a wrapping machine. A pivoted detector 36 operates an alarm if a packet is missing from the belt. If the wrapping machine stops, the cam 35<1> driven thereby, also stops and the presser 35 if in the lower position,. prevents the feed of more cartons. If the presser is raised, the first packet in the guides 34 acts as a stop and prevents further feed. A modified form of detector and stop-motion is illustrated in Figs. 5 - - 7 (not shown). According to this construction, the wrapping machine is stopped if the supply of filled cartons fails, and if the wrapping mechanism stops the cartons are diverted into a receptacle.
