Definitions

  • This invention relates to a machine for applying handles to containers and, more particularly, to such a machine for auto matically applying plastic handles to paperboard containers.
  • the handle-applying apparatus of the aforementioned patent is semiautomatic, that is, the container gable is automatically punched and the handle is snapped and locked automatically.
  • the plastic handle is spread and placed on the container and the male member is inserted through the punched hole in the container gable manually.
  • some operations for example, where the number of containers to which plastic handles are to be applied is limited or in which the containers,
  • the number of containers filled and process is relatively high.
  • the containers, after they are filled, are automatically loaded into crates or cartons.
  • an operator is not required to place the containers in crates or cartons and is not otherwise available to put the handles on the containers and insert the male member of the fastener through the punched gable hole.
  • the number of containers processed, and the speed required in processing does not readily lend itself to manual positioning of the handles on the container.
  • space is limited, such machine in which the handles are manually placed on the container is too large and not practical.
  • the gable of the container is punched, the handles are sorted and fed to the handle-applying station, one-by-one and one after the other, and applied to the container, the male fastening member is inserted through the punched hole in the container gable, and the female member is snapped over the male member. The end of the male member is then compressed and the container, with the handle applied and locked, is fed to the crate or carton loading station. All of this is accomplished in a fully automatic operation.
  • the plastic handles are shipped to the filling plant, lose and in a box and are dumped into a vibrating feeder hopper from which the handles are fed, one after the other. From the vibrating feeder hopper, the handles fall onto an inclined feeding beam and slide, by gravity, down such beam, to the handle applicator. At such applicator, the leading-most handle on the beam is stripped from the beam, fed onto a mandrel, the male and female handle-attaching members are spread over the container gable, and aligned with the punched hole in the gable. In order that this might be done, the gable is depressed. The male member'is inserted through the punched hole in the gable and the female member is snapped over the projecting end of the male member.
  • the handles applied to the container by the apparatus of the instant invention are plastic and because they are plastic, such handles are not always uniform.
  • the handles may be twisted or warped, the male and female attaching members may be misaligned, the handles may not be flat and such handles may vary, one from the other, in a variety of ways.
  • Such variations can, of course, adversely affect sorting, feed and application of the handles.
  • a warped or distorted handle can, and often does, block the sorting and feed of the handles, one after the other,

As best shown schematically in FIG 33, when closed, switch 291 energizes the solenoid-valve control of double-acting cylinder 64, activating the cylinder which pushes handle applicator 74. As handle applicator 74 advances downwardly fingers 262, 264 engage the handle on mandrel 222 and slide the handle down along the mandrel.
  • Angular ends 254, 256 and tapered extensions 258, 260 of mandrel 222 as the handle is advanced downwardly thereon by fingers 262, 264 opens up the attaching end of the handle to pass over the container gable.

This is important because the height of the filled and sealed container may vary, from container to container, as much as one-quarter of an inch. With shorter containers, little or no depression of the gable will occur while, with taller containers, the depression is increased. By depressing the taller containers, alignment of the male attaching member of the handle with the hole.
