Definitions

  • the present invention pertains to apapratus for heat treating containers, and more particularly relates to an improved carrier for conveying containers, such as cans of food, through a cooker or cooler.
  • FIGURE 1 is a perspective of a portion of a reel and spiral type heat treatment apparatus particularly showing the discharge end thereof with an end plate removed, certain parts being cut away and other parts being shown in section.
  • FIGURE 2 is an enlarged end elevation of the apparatus of FIGURE 1.
  • FIGURE 5 is an end elevation of a modified form of a container carrier which is used when super agitation is required.
  • FIGURE 6 is an end elevation showing conventional, angle-type container carriers used with the well known reel and spiral type of cooker or cooler.
  • FIGURE 7 is an end elevation of a third embodiment of the container carrier of the present invention.
  • the heat treatment apparatus 10 (FIG. 1) of the present invention is of the well known reel and spiral type and may either be a pressure type cooker or cooler as shown in FIGURE 1 or an atmospheric type cooker or cooler.
  • the heat treatment apparatus 10 comprises a reel 11 which is continuously driven in a clockwise direction as indicated by the arrows A in FIGURES 1 and 2.
  • the reel 11 is journalled in end Walls (not shown) of a housing 12 which includes a cylindrical shell 13.
  • a T- shaped spiral track 14 is secured to the inner surface of the shell 13 and extends throughout the entire length of the shell.
  • Containers C are fed into the housing 12, one
  • the containers are received in elongated carriers 17 which extend the full length of the housing 12 and are equally spaced along the outer periphery of the reel 11 of which they are a part.
  • the containers are advanced longitudinally of the reel in the direction of arrow B by the continuously rotating reel between adjacent runs of the spiral track 14 which causes the containers to be moved longitudinally of the axis of the reel 11.
  • a continuously driven discharge valve 18 which includes a pocketed rotor 19 and is arranged to discharge the processed containers from the heat treatment apparatus 10.
  • the apparatus 10 may be of the type disclosed in the patent to Wilbur 2,536,116 and reference may be had to said patent for a more complete description of any part of the mechanism that is not described in detail herein.
  • the reel 11 is mounted for rotation about an axis D (FIG. 2) which is disposed between and below and parallel to the axis D about which the cylindrical shell 13 is generated. Accordingly, the reel 11 is mounted eccentrically relative to the cylindrical shell 13 and relative to the spiral 14 which is concentric with the shell. This eccentric relationship between the reel 11 and the shell 13 permits the distal ends 21 of the carriers 17 to be positioned closer to the lower half of the shell 13 than to the upper half thereof.
  • the containers gravitate radially outward and roll along the inner surfaces of the spiral base flanges 22 of adjacent runs of the spiral track 14, which base flanges are welded to the inner surface of the cylindrical shell 13.
  • This eccentric mounting of the reel 11 aids in gently handling containers which may vary considerably in diameter, as indicated by the cans C1 and C2 in FIGURE 2.
  • the eccentric mounting also aids in attaining more effective pushing of the containers upwardly along the left side (FIG. 2) of the spiral track 14, since the carriers 17 contact the containers at lower points on their peripheries than is possible with a reel that is concentric with the shell.
  • the radially-extending web 31 (FIG. 4) of the spiral track 14 is made slightly shallower than normal in radial dimension in this lower half of the cylindrical shell 13. Because the reel 11 is eccentric relative to the cylindrical shell 13, the upper half of the web 31 of the spiral 14 has a radial dimension slightly greater than its lower half to compensate for'this eccentricity.
  • the U-shaped carriers 36 will add agitation to the containers since the containers positioned therein will not only roll along'the base flanges 22 of the spiral track 14 during the lower, half of their travel through the shell 13, but will also gently rock' back and forth in their carriers'36 asthe U-shaped car; riers move around the upperxhal-f of the reel 11.
  • the contents of the containers are agitated throughout their entire travel through the heat treatment apparatus 10. It will also be appreciated that the small containers are subjected to a greater amount of agitation than the large containers since they will rotate faster when in contact with the base flanges 22, and since they will roll back and forth more freely when supported within the concave surface of the associated carrier 36.
  • a continuously driven horizontally disposed reel mounted for rotation about a first axis, a plurality of carriers on said reel for supporting containers therein, a spiral track surrounding and spaced from said reel, a Web of variable thickness included in said track and projecting inwardly a greater distance from the upper half of said track than e051 the 7 lower half for advancing the'containers longitudinally convex surface terminating in a distal end disposed closely adjacent said spiral 'track and cooperating 'with of said reel, said spiral track being generated about aiseca "ond'axis which is disposed parallel to and above said first axis, each'of said carriers having 'a concave and a i adjacent carriers to define a lplurality of pockets of compound arcuate form, eachof said compound arcuate ⁇ distal end then roll into contact with said jspiral track,
  • said convex surface being arranged to partially support containers longitudinally of said"reel incident to rotation of said reelfeach' of said carriers-having'a distal end the container'as said pocket is moved'upwardly' to subsequently lift the container to a positionwherein it will roll away from said track and against said concavesurface of said pocket.
