Definitions

  • the invention relates to an overhead track for controlled turning of suspended carcasses comprising a rail, trolleys advancable thereon and rotatably mounting hangers for suspending carcasses therefrom, means for positively advancing the trolleys along the rail, and stationary abutments disposed laterally of the rail to be engaged by the hangers passing along the track, at a location on the hanger spaced from the rotational center thereof for rotating the hangers, so that the suspended carcasses when being carried along the track are turned continuously for instance to be exposed at all sides thereof to processing members provided along the track at opposite sides thereof.
  • the present invention has for its object to provide reliable and simple means for effecting a positive uniform turning of the hangers and the carcasses suspended therefrom, and for this purpose there is provided an arrangement in an overhead track of the kind referred to above wherein the rail has a sinuous portion and the abutments are disposed at one side of the rail opposite the concave bends thereof.
  • an overhead track for controlled turning of suspended carcasses comprising:
  • hangers rotatably mounted on the trolleys for suspending carcasses therefrom;
  • FIG. 1 is a plan view of an overhead track incorporating the turning arrangement according to the invention
  • FIG. 2 is a diagrammatic plan view of the overhead track illustrating the turning process
  • FIG. 3 is an enlarged vertical sectional view, partly an elevation, of the overhead track.
  • FIG. 4 is a side elevation of a roller of another embodiment than that disclosed in FIG. 3.
  • an overhead track comprising a tubular rail 12.
  • On this rail are supported overhead trolleys l3 having support rollers 14 running on the rail, and these trolleys are movable along the rail and are provided at the lower end thereof with a hanger 15 which is centrally connected with the trolley by means of a pivot 16 to be rotatable about a vertical axis and provides two opposite arms each forming a hook end.
  • the overhead track may be extended over an arbitrary distance and may comprise straight and curved portions as well as switches.
  • the trolleys 13 may be moved along the rail by manually pushing or pulling the carcasses suspended from the hangers or the overhead track may be provided with mechanical means for advancing the trolleys along the rail.
  • the overhead track has two sinuous portions as shown in FIG. 1.
  • sinuous includes not only a form which follows a mathematic sinuous curve but also other forms more or less resembling the mathematic sinuous curve.
  • the rail forms bends 12a to 12d in a first sinuous portion and bends 12f to 12k in a second sinuous portion a straight portion l2e being provided between the sinuous portions.
  • An endless conveyor chain 17 (indicated by a dot and dash line in FIGS.
  • the conveyor chain 17 passes over two reversing sprockets 18 and 19, rotatably mounted in the beam structure, sprocket 18 being operatively connected with an electric drive motor 21 for the conveyor chain.
  • the chain is guided by guiding sprockets 22a to 22d provided alternately at one side and the other of the rail each opposite one of the bends 12a to 12d at the concave side thereof, guiding sprockets 22f to 22k, provided alternately at one side and the other of the rail each opposite one of the bends 12f to 12k at the concave side thereof, guiding sprockets 22c and 22e provided at the straight portion l2e of the rail opposite the transition between the bend 12d and the straight portion l2e and opposite the transition between the bend 12f and the straight portion l2e, respectively.
  • Each guiding sprocket is an idling sprocket and is rotatably mounted on a vertically depending stub shaft 23 supported by the beam structure 10, by means of ball bearings 24 as will be seen in FIG. 3.
  • the chain has projecting driving dogs 25 for engagement with the overhead trolleys 13.
  • Means for guiding the chain when returning between sprockets l8 and 19, spaced laterally from the rail 12, comprise a circular plate 26 rotatably mounted on the chain at each driving dog, and a straight channelled guide rail 27 supported by the beam structure and slidably receiving the plates.
  • the stub shaft 23 for the guiding sprockets 22a to 220 is provided with an extension 28 fixedly connected therewith to form an abutment for the hangers.
  • the same arrangement is provided for the stub shafts 23 of the sprockets 22e, 22f, 22h, and 22k.
  • two types of rollers, 29 and 29', respectively, are provided and the reason therefor will be explained below.
  • a hanger 15 is positioned in position A transversely of the rail 12 when the advancement thereof is started by means of the conveyor chain 17 which advances the trolley along the rail 12 with the hanger in said position to the bend 12a where the hanger engages the roller 29' on the extension 28 coaxial with the sprocket 22a the hanger being rotated clockwise, as seen in FIG. 2, through position B to position C which is attained when the trolley is substantially opposite the bend 12b.
  • the hanger will engage the roller 29 on the extension 28 coaxial with the sprocket 22c and, thereby, will continue to rotate clockwise through position D to position E when the trolley is passing along the bend 12c and reaches the center of the bend 12d.
  • the hanger now engages the roller 29' on the extension 28 coaxial with the sprocket 12c and attains position F and then position G.
  • the hanger When carried along the straight portion 12e the hanger then will engage the roller 29' on the extension 28 coaxial with the sprocket 22f at the other side of the rail 12.
  • the hanger engages the roller 29' on the extension 28 coaxial with the sprocket 22h so that the hanger will arrive at position M and then will be further rotated in the counterclockwise direction to leave.
  • the second sinuous portion of the rail substantially in a position wherein the hanger is disposed longitudinally of the straight portion of the rail connected to said sinuous portion.
  • Carcasses are suspended from the hangers 15 by hooking the hind legs onto the ends of the hangers and are carried along the rail, through different processing stations in the slaughter-house the back side of the carcass usually being the leading side of the transported carcass. It is therefore presumed that the carcasses arrive at the first sinuous portion of the overhead track according to FIGS. 1 and 2 in this position. For instance, it may be assumed that the carcasses when carried along the sinuous portions of the overhead track will pass through a dehairing apparatus wherein the carcasses are to be turned continuously in order to be treated by scrapers or other tools at all sides, or through an apparatus for hot water treatment of the carcasses such as the apparatus described in U.S. Pat. No. 3,343,477 of Sept. 26, 1967.
  • the arrangement shown and described herein may be included into an overhead track system for turning the carcasses carried thereon over distances of an arbitrary length in the desired direction in order to provide a processing or treatment of the carcasses at each side thereof when the carcasses are carried through different processing stations.
  • the arrangement may also be used for turning the carcasses when they are passing a veterinary inspector to enable him to examine the carcass from all sides thereof without having to manually turn the carcass.
  • the conveyor chain may be arranged above the rail and may be guided along the sinuous portions thereof by means of sprockets as shown and described but it is also possible to guide the conveyor chain in the tube forming the rail, the chain in that case having driving dogs projecting through a longitudinal slot in the tube to drivingly engaging the trolleys.
  • An overhead track for controlled turning of suspended carcasses comprising:
  • hangers rotatably mounted on the trolleys for suspending carcasses therefrom;
  • the driving means comprises an endless chain havin alternate rollers each have a portion of greater diamedriving dogs for engagement with the trolleys and 5 a that f e t of the rollerswherein the chain is guided by sprockets disposed at ovefhead track as claimed in Claim wherein opposite sid f th il, t b i ll f ll h there 18 provided after a row of abutments at one side of sinuous portion h g a first sinuous portion of the rail a row of abutments at 3.
  • An overhead track as claimed in claim 2 wherein the side Ofa second sinuous Portion of the faileach abutment comprises a Stub h ft the stub h ft l0 7.
