Definitions

  • the current conventional process for manufacturin packaged cigarettes includes a making machine which forms the individual cigarettes and delivers them on a belt commonly termed a catcher belt. From the catcher belt, the cigarettes are loaded, either by machine or by hand, into a portable receptacle, commonly called a tray, holding several thousand cigarettes. After a tray is filled at the making machine, the tray is transported, either on a conveyor or by a truck, to a packing machine. There the cigarettes are counted into groups of a predetermined number (usually twenty), and then packed.
  • the cigarettes from the tray are fed into a hopper, from which groups (usually twenty to a group) are counted and arranged in the relatlve positions they will have in the finished package.
  • groups usually twenty to a group
  • Each counted group is then compressed laterally and forced endwise into a hollow arbor, open at both ends, and flared outwardly at the receiving end so as to guide the entering cigarettes.
  • the arbor has internal lateral dimensions slightly smaller than those of a finished package of cigarettes, and external lateral dimensions about the same as a finished package.
  • the arbor is, however, somewhat longer than a finished package.
  • an inner Wrapper is formed around the discharge end of the arbor, closing that end.
  • a cup, or label-carrying paper wrapper, open at one end, is then Wrapped over the inner wrapper.
  • the cigarettes are then pushed out of the arbor through the closed end, carrying the inner Wrapper and the cup with them. Since the cigarettes have been tightly compressed in the arbor, they expand as they leave the arbor, filling the inner wrapper.
  • the open end of the inner wrapper is then closed.
  • the inner Wrapper is of foil laminated with paper. A sealing strip is applied transversely across the open end of the cup.
  • the packages from the packing machine are then transferred to a Wrapping machine, where they are enclosed in an outer wrapper, usually of transparent plastic material, e.g., cellophane.
  • an outer wrapper usually of transparent plastic material, e.g., cellophane.
  • Cigarette-making machines commonly in use produce cigarettes at a rate equal to about half the rate at which a packing machine can pack them. Consequently, it is usual to employ about twice as many making machines as packing machines. The rate of output of the packing machines is limited by the slowest operation performed in them, which is the counting and arbor filling operation.
  • the hollow arbors for containing the cigarettes during the packing operation have been fastened to a conveyor mechanism, such as a rotary drum.
  • the arbors are conveyed to and from fixed locations and are not susceptible of being selectively conveyed to alternate positions.
  • the entire packing operation including the transfer of cigarettes to and from the machine, ..is brought to a halt because the conveying operations cannot be changed to compensate for the failure.
  • the arbors are not fastened to a conveyor mechanism, and advantageously they do not have flared ends. Flared guides are employed at arbor-filling points only. The absence of flared ends as well as attachment to a conveyor mechanism renders the arbors suitable for being conveyor to alternate locations for accumulation in the event of machine failure, e.g., and generally facilitates a speeding of the packing operation.
  • Another object of the invention is to provide packaging apparatus and methods which permit the selective conveying of arbors for packaging a product to alternate locations.
  • Another object of the invention is to employ a freely movable arbor in the packaging of a product.
  • a further object of this invention is to employ a freely movable arbor whtch may be stacked with other arbors for accumulation.
  • a freely movable arbor i.e., a. releasably securable arbor
  • the term freely movable arbor as well as the term releasably securable arbor as used herein is intended to designate a hollow container which is not fixedly attached to any mechanism but which is freely movable in the sense that it may be transferred from one location to another and, in particular, may be transferred to any one of several alternate locations.
  • An arbor is regarded as freely movable or releasably securable even though it is held in place on a conveyor, for example, by some form of mechanical or magnetic retainer.
  • the term means that at one or more points the arbor is unrestrained so that it may be transferred from one conveying means to another, for example.
  • a product to be packaged can be placed within the arbor, at an arbor-filling unit which may be, e.g., at a product-making machine, and then the arbor can be conveyed to a wrapper-forming machine in which a wrapper is wrapped about the arbor and the product therein. Thereafter the wrapper and the product together may be disassociated from the arbor, and the wrapper may then be completed so as to completely enclose the product.
  • the empty arbor is then returned to the arbor-filling unit to be filled again with the product to be packaged.
  • a typical sequence might be first to fill empty arbors with cigarettes and then to wrap the filled arbors with an inner wrapper.
  • the conveying system may include accumulating stations for accumulating em pty arbors as well as arbors filled with cigarettes but unwrapped with the packaging material. In this fashion, shutdowns in the arbor-filling station or the wrapper-forming station can be tolerated without causing a complete cessation of the overall process.
  • empty arbors first may be wrapped with a packaging material and then filled with a product to be packaged.
  • This sequence has particular application tothe packaging of finely divided material, for example, soap flakes.
  • the system may include accumulating stations to accumulate empty arbors and arbors filled with product.
  • trays of cigarettes may be carried to a packing machine as has been done in the past, and the cigarettes may then be placed in the freely movable arbors, or one or more cigarette-making machines may supply cigarettes directly from the catcher belts thereof into a hopper for conventional counting into the conventional lots of twenty cigarettes each to be then transferred to the freely movable arbors. It is particularly advantageous to transfer cigarettes directly from cigarette-making machines into the freely movable arbors since the risk of deformation and damage by handling, transportation and storage is greatly lessened because the arbors provide a holder for the cigarettes to prevent damage.
  • the cigarette-filled arbors may be transported by conveyor belt or any other means to one or more locations where it is desirable to locate the packing and wrapping machines as well as accumulators. With this arrangement, making machines and packing and wrapping machines may be handled in a group, and the shutting down of one or more machines will not adversely affect the operation since the arbors may be shunted to and from different machines to accommodate different combinations of operative machines.
