Definitions

  • ABSTRACT OF THE DISCLOSURE An installation for the thermal treatment of filled bottles or tins, accommodated in carriers passing through the installation by means of a conveyor, each carrier comprising at least a lever and a reaction member cooperating with zig-zag rails in the interior of the installation for imparting a rocking movement to the carriers.
  • the invention relates to a device for the pasteurization or sterilization of commodities packed in containers, such as a liquid in a tin or bottle, consisting of a space wherein the commodities receive treatment and through which an endless conveyor advances along a looped portion of its path, the conveyor both entering and leaving the said space through a liquid seal, and a number of carriers for the containers to be treated being pivotally supported, means being provided for imparting a rocking motion to the carriers when they traverse the treatment space, said means comprising at least one lever connected with the carrier and a fixed zig zag guide rail.
  • This known device is specially intended to ensure that the contents of the containers remain homogeneous as a result of a slow periodical movement of the carriers. This fact is of importance when substances are packed in the containers which tend either to float on the surface (like fats) or to settle (like albumen or sugar).
  • each carrier in the conveyor is supported in an area in the vicinity of the line extending in the longitudinal direction of the carrier and through the centre of gravity thereof.
  • the invention relates especially to a device wherein in a way known per se each carrier consists of an oblong box, or of a row of adjacent cells, supported at both ends by a conveyor.
  • An other object of the invention is to provide a construction in which the lever does not only serve as a rocking member, but also as a suspension element for swingably suspending the carrier in the conveyor.
  • FIG. 1 is a side view representing the complete installation with removed side wall so that the interior of the device is visible;
  • FIG. 2 shows to a larger scale a side elevation of a part of the device according to FIG. 1;
  • FIG. 4 is a view according to the line IV-IV in FIG. 3;
  • FIG. 5 shows to a still larger scale a section through the carrier on the line V-V in FIG. 4.
  • the installation comprises a number of turrets or columns 1 disposed on a common base 2.
  • the turret 1 at the left in FIG. 1 constitutes in the usual way the entry and the turret at the right constitutes the exit for an endless conveyor 3 moving along a looped path through the turrets 1.
  • the second turret 1 from the left in FIG. 1 constitutes the treatment space proper and a definite pressure and temperature related to the aimed treatment are maintained therein.
  • an inclined path portion 4 of the conveyor 3 constitutes the connection between the exit and the entry of the device. In this path portion 4 are provided in a way known per se the feeder and the discharge station indicated by an arrow 5 and 6 respectively for the supply of the containers to and the discharge thereof from the carriers 7 of the conveyor 3.
  • each carrier 7 Connected with each carrier 7 is at least one lever 8 as will be readily appreciated from the FIGURES 35.
  • each carrier 7 consists of a long gutter 9 shaped as a fiat box which at its two ends 10 is provided with a lever 8.
  • Each lever 8 has a free end 11, while the other end is provided with a hub-shaped part 12, of which one side 13 is secured to one end 10 of a carrier 7 and of which the other side 14 carries both a reaction member 15 and a connecting pin 16.
  • This pin 16 is rotatably mounted in a broad link 17 of the conveyor chain 3 which is built up from broad and narrow links 17 and 18 disposed in alternate order.
  • the hub-shaped part 12 is connected with the end of the carrier 7 in such a way that the centre line of the pin 16 constituting the carrying member proper of the carrier 7, coincides with a line 19 extending through the centre of gravity of the carrier.
  • the lever 8 cooperates on the one hand with a zig zag guide rail 20 and a straight supporting rail 21.
  • the free end 11 of the lever 8 is bearing against the rail 20 and the reaction member 15 of the hub-shaped part 12 of the lever 8 cooperates with the rail 21 (see FIG. 3).
  • the guide rail 20 and the supporting rail 21 are situated in a common plane which is substantially parallel to the direction of advance of the conveyor 3 and perpendicular to the line 19 through the centre of gravity of the carriers 7.
  • the free end 11 of each lever 8as contemplated in the direction of advance of the conveyor 3 is trailing.
  • each carrier 7 has substantially the shape of a fiat box 9 which on the one small side 22 is narrowed in order to accommodate a bottle neck, and on the other small side 23 is entirely open with a thresholdlike narrowing 24.
  • a bottle as well as a tin are to a certain limit confined within the carrier 7.
  • the angle of oscillation of the carriers 7 is substantially held within a range between 2030 which is achieved by properly dimensioning the lever 8 and the rails 20 and 21.
  • This rocking movement is repeated many times in both the ascending and descending parts of the looped path of the conveyor 3 in the aforementioned turrets 1.
  • the fact thatt he carriers are supported in an area in the proximity of the line of gravity 19 is advantageous in that the forces required for the rocking movement remain small.
  • the trailing position of the end of the lever 8 is furthermore advantageous in that the development of considerable reaction forces is avoided.
  • the positioning of the levers 8 in respect of the plane through the conveyor 3 (see FIG. 5) in such a way that one is the mirror image of the other ensures that an adequate force is exerted on each carrier 7 both in the one and the other direction when same is rocked.
  • a third advantage of the invention consists in that due to the special construction of the lever 8 and the positioning of the rails 20 and 21 the occurrence of bending or torsional forces in the conveyor chain and in the carriers is avoided.
  • the bearing of the carriers 7 in the conveyor 3 by means of the pins 16 is hereby simplified.
  • An installation for the pasteurization or sterilization of commodities packed in containers consisting of a space wherein the commodities receive treatment and through which an endless conveyor advances along a looped portion of its path, the conveyor both entering and leaving the said space through a liquid seal, and a number of carriers for the containers to be treated being pivotally supported, means being provided for imparting a rocking motion to the carriers they traverse the treatment space, said means comprising at least one lever connected with the carrier and a fixed zigzag guide rail, the improvement consisting in that:
  • each carrier in the conveyor is supported in an area in the vicinity of the line extending in the longitudinal direction of the carrier and through the centre of gravity thereof;
  • a supporting rail is provided in addition to the guide rail, so that each carrier in the conveyor is beating against the supporting rail in order to absorb the reaction force generated by the guide rail.
  • each carrier consists of a long gutter comprising a row of adjacent cells supported at both ends by a conveyor, characterized in that a lever and a set of rails are provided at the two ends of the carrier, the angular position of the two levers with respect to the plane through the two conveyors being such that one is the mirror image of the other.
  • a carrier is substantially shaped as a flat box which on its one small side is narrowed in order to accommodate a bottle neck and on its other small side is entirely open with a thresholdlike narrowing.
  • each lever on its one end is provided with a hubshaped part of which one side is secured to an end of a carrier and of which the other side constitutes both the reaction member cooperating with the supporting rail and the connecting pin with the conveyor.
