Definitions

  • This invention relates in general to machines for packing bottles, cans and other like articles and deals more particularly with an improved shifting grid for use with such a machine to direct and control the gravity fall of a row arranged charge of articles into a container.
  • Bottles, cans or like articles are delivered to a packing machine of the aforedescribed type in an upright position and are guided to a dividing mechanism which separates the articles into lanes for forming a desired charge pattern. Thereafter, the articles are conveyed to a charge forming area on a grid assembly.
  • the assembled charge is loaded through the grid assembly and guided by one or more chutes into an empty space or container which has been raised to a loading position by a case feed lift table.
  • the filled case is lowered and discharged from the case lift table and the cycle repeats itself.
  • the grid assembly is made to handle articles in a limited range of sizes, as, for example, bottles in a limited range of diam eters.
  • a grid assembly which includes a frame for receiving and assembling a row arranged charge of articles from an article packing machine and a chute for directing and controlling the gravity fall of the charge into a case or container.
  • One end of the frame and the chute is adjustable through a range of positions to adapt the grid to accommodate charges in a relatively wide range of article sizes.
  • FIG. 1 is a fragmentary plan view of a bottle packing machine showing a shifting grid embodying the present invention mounted thereon.
  • FIG. 2 is a somewhat enlarged fragmentary sectional view taken along the line 22 of FIG. 1.
  • FIG. 3 is a fragmentary side elevational view of the machine and grid of FIG. 1, portions of the grid supporting members shown broken away.
  • FIG. 4 is a fragmentary end elevational view of the machine and grid of FIG. 1, portions of the grid sup porting members shown broken away.
  • the bottle packing machine indicated generally at 12 and partially shown in the drawings is conventional and need not be described in detail.
  • the machine 12 comprises an in-feed conveyor 14 which transports bottles of uniform size indicated at B, B and b, b from a dividing mechanism (not shown) forwardly in parallel rows between stationary longitudinal guide plates 16, 16.
  • the leading bottles in the rows of bottles enter the grid assembly between bottle guides 18, 18 and 19 which form a part of the grid.
  • the leading bottles are blocked and held in place between the bottle guides by engagement with the rear surfaces of a series of transversely shiftable longitudinally extending pushers 20, 20 and 21 operated by means hereinafter described.
  • the pushers are movable between a blocking or broken-line position, as shown in FIG.
  • the rows of bottles are advanced by line pressure from between the stationary bottle guides 18, 18 and 19 and slide forwardly between longitudinal members or guide plates 22, 22 along riding strips or rails 24, 24 operatively associated with the pushers and also forming a part of the grid.
  • the guide plates 22, 22 define a series of similar vertically open longitudinal spaces adapted for downward passage of rows of bottles.
  • the front or leading bottle in each row actuates a detecting switch 26.
  • the switches 26, 26 are carried by a longitudinally adjustable barrier or stop indicated generally at 28 and sense the presence of a full charge on the grid to control operation of the aforementioned means for shifting the pushers 20, 20 and 21.
  • the said operating means shifts the pushers to their blocking position.
  • the rails 24, 24 move with the pushers and slide transversely beneath the bottles to a releasing position wherein each of the rails is respectively vertically aligned with an associated one of the guide plates 22 whereupon the bottles fall by gravity through the open spaces defined by the plates 22, 22 and through an adjustable chute positioned therebelow and indicated generally at 30.
  • a lift table 34 which may, for example, comprise a part of the packing machine 12 is adapted to elevate the cases in succession to a bottle receiving position beneath the grid and is lowered to discharge packed or filled cases and to receive empty cases from an empty case i-n-feed conveyor (not shown). Cases are, of course, raised or lowered in properly timed relation with the transverse shifting movement of the pushers 20, 20 and 3 21 by a suitable control means. Such control means are or may be conventional and a showing and description thereof is deemed unnecessary for a full understanding of the grid of the present invention.
  • the grid may be adapted to accommodate charges of articles in a relatively wide range of sizes by adjusting the position of the barrier 28 to vary the length of the spaces defined by the plates 22, 22.
  • the adjustable barrier 28 is shown in a full-line position corresponding to an adjusted position of the grid to accommodate bottles having a diameter substantially equal to the transverse spacing between adjacent guide plates 22, 22 in a row arranged charge with ix bottles in each row.
  • the barrier is adjustable through a range of positions between its full and broken-line position.
  • the grid 10 accommodates rows of smaller bottles such as indicated at b, 12 arranged with six bottles in each row.
  • the chute 30 is also adjustable to suit the container or tray for receiving the charge.

  • the lower section has longitudinally spaced transversely extending front and rear support members indicated generally at 36 and 38, respectively, connected together by transversely spaced and longitudinally extending threaded tie rods 40, 40.
  • the front and rear support members 36 and 38 are of like construction and each comprises upper and lower generally rectangular bars 42 and 44 secured together in parallel but vertically spaced relationship by generally U-shaped clamp members 46, 46 fastened to the ends of the rods 40, 40.
  • a support member 48 extends upwardly from each rod generally adjacent the rear support member 38.
  • the two support members 48, 48 are connected together at their upper ends by a transversely extending threaded rod 50 which passes through the guide plates 22, 22 and provides support for the latter plates as well as a means for adjusting the transverse spacing between them.
  • the lower grid section also provides support for the bottle guides 18, 18 and 19.
  • Each guide 18 is formed from a generally L-shaped plate and includes a horizontally disposed portion and a vertically disposed portion.
