  • ABSTRACT Disclosed herein is a device for automatically varying the operating speed of a cigarette packaging machine in response to the presence or absence of defective groups of cigarettes to be packaged.
  • the device includes a sensing member for sensing the number of cigarettes in a group, and for sensing the amount of tobacco in each cigarette.
  • Control means are provided to maintain the operating speed of the machine at a high rate until a defective group of cigarettes is sensed by the sensing member, whereupon the operating speed is decreased to prevent malfunctions which may otherwise result from operational changes due to the detection of such defective groups.
  • the control means operates to again speed up the machine after a predetermined duration of sensing by the sensing member during which no defective groups of cigarettes are detected.
  • the cigarettes are first assembled in overlying multi-layered groups, each group having a number of cigarettes corresponding to the desired number to be wrapped in a single packet.
  • the cigarette groups are then checked to ensure the presence of the proper number of cigarettes and to ensure that each cigarette has a predetermined minimum amount of tobacco therein.
  • the cigarette groups are wrapped by a multi-sheet wrapping, that is, by a first or inner tin foil wrapping, a second or outer paper material wrapping forming the label, and a seal, small stamp or label.
  • the higher rate of speed corresponds to the running speed, also referred to as second speed, which can be reached when no defective cigarette groups are found over a determined time interval wherein the machine operates at afirst speed which is lower than said running speed, at the beginning and renewal of the output cycle and when finding defective cigarette groups to be excluded from the machine.

  • the cigarettes are maintained in overlying layers by pushers which are successively arranged to slide on the base plate of the loading hopper 1 to form groups having the desired amount of cigarettes as shown for example in the U5. Pats. Nos. 3,435,940 and 3,520,394 to the same applicant.
  • sensing means 5 and 6 are arranged, these sensing means being suitable to detect, in these groups of cigarettes, both the lack of one or more cigarettes and an insufficient tobacco filling therein (see FIGS. 2 and 3).
  • Sensing pins 7, making up these sensing means are mounted on supports 5a and 6a reciprocated by shafts 8 and 9 and are so arranged as to face the two ends of each cigarette in the group being sense.
  • the sensing means 5 and 6 are shifted away from the conveyor 4 until a group of cigarettes is disposed therebetween, whereupon the devices 6 and 7 are moved toward each other.
  • the pins 7 are retained in position by readily compressible springs and the pins probe the ends of each cigarette during the forward movement thereof to give a signal upon detection of any absence of one or more cigarettes or an insufficiency of tobacco in any one cigarette.
  • FIG. 4 illustrates an example of an electrical diagram for controlling the above described high speed packaging machine in accordance with the principle of the present invention, and shows at M an electric motor, such as that designated M132S4/6 CV 4/2,? manufactured by FIMET, having dual sets of input leads for alternate connections to a potential source to operate the motor according to two different speed rates of the packing machine; two relays or telebreakers TL' and TL for controlling said electric motor; three telebreakers R R R a timing-switch element T characterized by a suitable capacitor C, for controlling said telebreakers TL, and TL and a pair of push buttons P and P wherein P is the starting pushbutton of the machine and P the stop pushbutton.
