Definitions

  • This invention relates to a floatation tank for continuously emptying large boxes, in particular boxes containing vegetable and fruit produce such as apples.
  • the instant floatation tank for continuously emptying large boxes, in particular boxes containing vegetable and fruit produce, characterized in that it comprises a tank having a water inlet and a front formed with an overflow outlet for the water and produce, at least one arm journalled in an intermediate position thereof, two box-type platforms supporting respective one of said boxes,and having at least one of their respective lateral sides open for the introduction and withdrawal of said boxes, the platforms being articulated at a bottom portion thereof to the ends of said arm, a drive unit for said arms adapted to rotate them so as to successively bring said platforms from a raised position of introduction and withdrawal of a box to a lowered position of immersion of the box into the tank, a kinematic means for connecting said platforms to said tank and operative to rotate the platforms relatively to the arms as the arms are being rotated to hold said platforms horizontal, and a means for automatically locking the boxes and mounted on the open sides of said platforms, being adapted to be deactivated with the platform at the box introduction or withdrawal position.
  • a tank according to the invention for continuously emptying large boxes 2.
  • the boxes 2, only shown diagramatically in the drawings, are as usual of a type formed from a plastics material, have a parallelepipedic shape, and are open at the top, while having their walls perforated.
  • the tank 1 has an open top box-like shape and has, front 3 and rear 4 walls, two inlets 5,6 for admitting water, whereat there are arranged, on the tank interior, shaped deflector diaphragms 7,8 which are adapted to generate a surface stream of water travelling in the direction of the arrow A; the wall 3 is formed with a wide flattened water outlet 9 which is extended into a wide flattened channel 10 of sort for carrying away the overflowing water and the produce floating therein.
  • trunnions 11 In a central area of the lateral sides of the tank 1, there are journalled in sealed relationship two trunnions 11 to an intermediate position whereon, inside the tank, are mounted two strong arms 12a,12b; on the tank exterior, there are keyed to the .
  • trunnions 11 respective sprocket wheels 13 which are connected by respective closed loop drive chains 14 to two sprocket wheels 15,mounted at the ends of a transverse drive shaft 16,at the exterior of the tank and in turn driven by a motor unit 16a, whose actuation results, in the arms being rotated in the direction of the arrow B to bring the arm ends to a configuration of immersion into the tank, and alternately in the direction of the arrow C to a configuration of lifting out of the tank.
  • the arms 12 are interconnected at their ends by two transverse idler shafts 17a,17b whereto respective platforms 18,19 are keyed; the platforms 18,19 are each comprised of a deck 20 which has, at the front and rear, two rows of cylindrical idler rollers 21 which facilitate introduction of the boxes by rolling engagement; the introduction of boxes takes place in a direction perpendicular to the plane of the drawing sheet of Figure 1 and the rollers 21 are rotatable each about a horizontal axis, parallel to the plane of the drawing sheet; on the sides of the deck, and under it, there extend two flattened isosceles triangle wings 22 for articulation to the shafts 17; at the front and rear, the decks 20 are joined to a forward face 20a and a rearward face 20b.
  • sprocket wheels 23,24 of like diameters which are made fast with the platform 18 and platform 19, respectively; mounted rotatably on the shaft 11 is a sprocket wheel 25 which is fast with the lateral side of the tank 1 and has the same diameter as the sprocket wheels 23,24.
  • the sprocket wheels 23,24,25 are kinematically connected together by a closed loop chain 26, there being provided two idler sprockets 27,28 mounted on the arm 12 which are adapted to hold the chain engaged with the sprocket wheel 25.
  • the arm 12a is advantageously of hollow construction; and that the sprocket wheels 23,24,25, chain 26 and idler sprockets 27,28 are mounted on its inside.
  • the means 29 comprise small fingers 30 pivotally connected by pins 31 to the face 20a of the deck 20 and having counterweights 32; from each of the tanks' lateral sides there extend upwards an upright 33 which has at the top a cam profile 34 extending therebetween and being adapted for abutment engagement with the counterweights 32 when the platforms reach their highest elevation or level.
  • the fingers 30 are adapted to prevent the boxes from sliding, whereas in the condition of maximum lift, the boxes would be released to slide on the rollers 21.
  • the stop means 29 allow this transverse movement in the position of highest elevation of the platform and stop such transverse movement of the boxes 2 when the platform is lowered owing to the disengagement of the stop means from the cam 34 and owing to the oscillating action of the counterweight 32 thereof. It should be noted that two stop means 29 may be provided for each box, one in front of the box and the other behind the box.
  • the lateral sides(i.e. those parallel to the plane of the drawing)of the platforms 20 may be either both open and equipped with a locking means 29, or alternatively, one side closed by a fixed lateral side and the other side equipped with the locking means 29; in the former case, the boxes would be introduced from one side and withdrawn from the other side of the platform, whereas in the latter case, they would be introduced and withdrawn from the same side.
  • the motor 16a driving the shaft 16, which is operated stepwise to successively and alternately submerge and raise the platforms into/from the tank, is operatively connected to sensors 3 for detecting the density of the vegetable and fruit produce floating in the tank, thereby, on the detected density dropping below a preset value, the empty box would be lifted off and a fresh one to be emptied loaded into the tank.
