Definitions

  • This invention relates to a cigarette supplying and stopping device used in a cigarette wrapping apparatus and more particularly to a cigarette supplying and stopping device used in a cigarette wrapping apparatus which has an automatic cigarette supply-stopping mechanism provided on an cigarette parallel-arranging device which arranges cigarettes in parallel and pile them in three steps in a staggered manner and prevents half-finished goods from being left on the intermediate portion of the wrapping apparatus when the operation of the wrapping apparatus is stopped.
  • a cigarette wrapping apparatus is provided with a cigarette parallel-arranging device which takes out cigarettes from a hopper or the like containing cigarettes randomly arranges the cigarettes in parallel and piles them in three steps in a staggered manner such that, of twenty cigarettes to be packed in a box, seven, six and seven cigarettes constitute the lower step, the intermediate step and the upper step, respectively.
  • the cigarette wrapping apparatus is further provided with a packing device for wrapping piled cigarettes with aluminum foil or wrapping sheets.
  • the cigarette wrapping apparatus is still further provided with a sealing device for attaching seals (sealing pieces, for example) to cigarette packages.
  • the cigarette parallel-arranging device, the packing device and the sealing device are integrally connected to each other to form a cigarette wrapping apparatus. Cigarettes put in the hopper or the like are sent out from the cigarette wrapping apparatus as packed final products.
  • cigarette wrapping apparatus The operation of cigarette wrapping apparatus is stopped when maintenance or repair is required.
  • stopping blocks or the like are manually inserted into cigarette supplying passageways in the cigarette parallel-arranging device to interrupt the passage of cigarettes and thereafter the cigarette wrapping apparatus is operated for a predetermined time. After all cigarettes and unfinished products are taken away from the interior of the cigarette wrapping apparatus, the operation of the apparatus is stopped.
  • the number of the cigarette supplying passageways is twenty which corresponds to the number of cigarettes in a box. It is not only very cumbersome and uneconomical to put the stopping blocks in the cigarette supplying passageways simultaneously but also it requires skill to do so. Further, when the cigarette wrapping apparatus must be stopped due to some operational trouble, it takes a long time to stop the apparatus.
  • the object of this invention is to provide a cigarette supplying and stopping device which readily and automatically stops the supply of cigarettes in a short time.
  • the cigarette supplying and stopping device is provided with a plurality of cigarette supplying passageways for transporting parallel-arranged cigarettes, stops disposed in the respective cigarette supplying passageways and retracted therefrom and a driving mechanism for driving the stops.
  • the stops In order to stop the operation of the cigarette wrapping apparatus, the stops project into the cigarette supplying passageways by means of the driving mechanism and cigarettes are held between the stops and the inner faces of the cigarette supplying passageways to interrupt the movement of the cigarettes.
  • the pressing force of the stops has a value which does not deform or collapse cigarettes but has a sufficient value to interrupt the movement of the cigarettes through the passageway.
  • the apparatus according to this invention is provided with an air cylinder whose pressing force is set such that cigarettes held between the stops are not deformed or collapsed but are held immovably in the passageway.
  • the apparatus according to this invention is further provided at the outlets of the cigarette supplying passageways with cigarette holding projections for securely but temporarily holding cigarettes which are being supplied.
  • a cigarette parallel-arranging device 1 has a hopper 2 into which a plurality of cigarettes are supplied from a known cigarette manufacturing machine (not shown) which is outside of the scope of this invention. Twenty cigarettes to be contained in a box are piled in three steps by means of the cigarette parallel-arranged device such that the lower, intermediate and upper steps include seven, six and seven cigarettes, respectively.
  • the piled cigarettes are supplied to a packing device 3 disposed adjacent to the cigarette parallel-arranging device 1, for automatically packing each set of twenty cigarettes to be contained in a box with aluminum foil or a wrapping sheet.
