Definitions

  • ABSTRACT Disclosed herein is an apparatus for supplying Cigarette containers to the loading mechanisms for hoppers of cigarette packaging-conditioning machines.
  • the apparatus supplies containers filled with cigarettes through a storage device so that the operating continuity of the cigarette packaging-conditioning machine is assured independently of the operating continuity for the cigarette manufacturing machine associated therewith.
  • the storage device intervenes to ensure maximum operating efficiency for both the cigarette manufacturing machines and for the packaging-conditioning machine by storing the containers of cigarettes produced by the manufacturing machine when a failure occurs in the packaging machine; and, by supplying the stored containers to the packaging machine during proper operation of all of the apparatus and upon failure of the manufacturing machine.
  • This invention relates to apparatus for feeding cigarettes to the hoppers of cigarette packaging-conditioning machines, and, more particularly, to apparatus of the type providing such a feed by containers or boxes which have been previously filled with cigarettes and supplied to a so-called hopper loading mechanism for said cigarette packaging-conditioning machines.
  • cigarette packaging-conditioning machines are fed with cigarettes supplied to the associated feed and assembling hoppers by manual, automatic or semiautomatic operations.
  • cigarette packagingconditioning machines it has been shown to be increasingly necessary to perform this supply function automatically.
  • automatic feed is provided so as to operate according to the so-called direct feeding, that is, by directly connecting the outlet of the cigarette manufacturing machines to the inlet of the packaging-conditioning machines, that is, to the feeding and assembling hopper thereof, or by supplying cigarettes to said hoppers by containers or boxes which have been previously filled and brought to a station where they are automatically or semi-automatically unloaded into the hoppers.
  • This invention particularly relates to the latter type of automatic feeding, that is to the type using containers or boxes previously filled with cigarettes, and is concerned with an apparatus for feeding said cigarette containers to the automatic hopper loading mechanisms of the packaging-conditioning machines, independently of operation continuity of the manufacturing machines by drawing, in case of need, said containers from a store or stock wherein these containers are regularly stored when the manufacturing machines are running, while the packaging machine is not or while it is running irregularly running.
  • the containers filled with cigarettes are subsequently individually loaded on a frame member rotatable about a horizontal axis, by arranging the same with the open side face thereof against a wall of said frame member.
  • the operator then wraps a flexible material tape, which is usually connected by an end to said frame member, above the open top face of the container thus positioned on the frame member, or arranges a rod, referred to as a bayonet; rotates said frame member about its horizontal axis of rotation overturning the container above the conditioning machine hopper to be supplied, with said face as wrapped by the flexible tape or closed by the bayonet, downwardly facing, removes said tape, or said bayonet, by slipping it out from between the upper level of cigarettes within said hopper and the lower level of cigarettes within the overturned container,
  • a mechanism of this character substantially provides a rotatable loading head which is located above the hopper to be loaded, and which is shaped so as always to have thereon two containers at an upset mirror-like symmetrical position so that such containers can be disposed alternately in an overturned position for cigarette supply into the hopper, and responsive means for detecting the unloading occurrence of such overturned container and for controlling half a rotation or revolution for said rotatable head to immediately replace the empty container with a full one.
  • the operations for removing the empty container from the rotatable loading head and replacing it with a full container are provided so as to be carried out either manually, or automatically or semiautomatically.
  • the store is capable of storing cigarettes as they appear at the outlet of the manufacturing machines, or as gathered in magazines according to a plurality of individual groups, each of which comprises the number of cigarettes intended to form the individual packets to be wrapped up, and even according to a number of these magazines in containers; and, in case of a failure of the manufacturing machine, to supply such stored cigarettes to the conditioning machine directly as said groups to be wrapped up without passing through the usual feeding and grouping hopper of conventional cigarette packaging and conditioning machines.
  • a further significant object of the present invention is to provide an apparatus not only capable of assuring the supply of containers filled with cigarettes to the hopper loading mechanisms for the packet cigarette conditioning machines in accordance with the above-mentioned primary object and without any need of changing the structure of the feed portion in conventional conditioning machines, but also capable of causing the store to intervene at any time in the production in accordance with the operating rate both for the conditioning machine (receiving rate or capacity) and for the individual manufacturing machines (delivery rate or capacity), by storing or supplying containers filled with cigarettes, so as to make every machine cycle always entirely usefully at the maximum operating rate, with an obvious substantial increase in the total output.
  • a still further object of the present invention is to provide such a feeding apparatus of containers filled with cigarettes to the hopper loading mechanisms for conventional packet cigarette conditioning machines which is capable of providing a substantial operating range in the production system through its supply store, by storing or supplying containers filled with cigarettes in accordance with the receiving and/or delivery capacities, respectively, at any time for the system machines and without any need of occupying space in addition to the ordinary plane surface as already involved by said machines forming said production system.
  • a still further object of the present invention is to provide such a feeding apparatus for attaining all of the above objects through a particularly simple operating structure, which can be readily carried out and is reliable in operation, simple and practical in use, and which is also and above all of a comparatively low cost in view of the performances provided thereby.

  • the feeding apparatus comprises a first continuous feeding conveyor for carrying successive cigarette containers from a transfer position or station to a station or position for receiving and transferring said overturning member; a second continuous conveyor, or store conveyor, for defining a receiving position and a transfer or feed position between said transfer position from the-first continuous feeding conveyor and said receiving and transferring position for the overturning member; a third continuous conveyor, or unloading conveyor of empty containers, for defining a receiving position of said empty containers from said receiving and transferring position of the overturning member; driving means electrically connected to said electro-sensitive means associated with said overturning member for independently operating said first, second and third conveyor; electro-sensitive means at said transferring position from the first feeding conveyor, electrically interconnected to the electro-connecting means for the conditioning machine operation; and pushing means also connected to said electro-sensitive means associated with the overturning member.
  • the pushing means is for subsequently transferring containers from said transferring position by the first feeding conveyor to the receiving position of the overturning member, or to the receiving and transferring position or feeding position of the second conveyor for storing, depending upon whether the conditioning machine is operating or not, and respectively, with the conditioning machine operating, from this last supply position of the store conveyor to the receiving position of the overturning member in case a container is not present at said transfer or supply position of the feeding conveyor, and again, from said receiving and transferring position of the overturning member to the receiving position of the third unloading conveyor for the empty containers.
