Definitions

  • Ovens are known that can be loaded at will by one or the other of their lateral sides.
  • the oven has a stopper which is placed in the opening of the door when it is not used in order to block the products which are put in the oven by the other door and put in place on a train of rollers.
  • the present invention relates to a stop device for a side-loading oven with which the stop can easily be retracted when the side of the load is changed.
  • This device in which the stopper is suspended from a fixed structure by means of an articulated parallelogram, is characterized in that it comprises, to ensure the deformation of the parallelogram and, consequently, the displacement of the stopper, a mobile counterweight along an axis integral with one of the parts constituting the parallelogram and means for moving this counterweight.
  • the counterweight is mounted on one of the wings of an L-shaped part, the other wing of which constitutes one of the elements of the articulated parallelogram.
  • the stopper 5 is supported by a structure constituted by three columns 6 a , 6 b and 6 c .
  • the stopper 5 is carried by an arm 7 articulated at 8 on the lower end of a connecting rod 9 whose upper end is articulated at 10 on the baluster 6 c .
  • the end of the arm 7 is articulated at 11 on a part 12 in L which is articulated on the baluster 6 a at a point 13 situated at the same height as the axis 10.
  • the axes 8, 10, 11 and 13 are the vertices of a parallelogram; the arm 7 is thereby kept horizontal.
  • the axis 13 is substantially at the top of the part 12 in L while the axis 11 is provided in the vicinity of the end of one of its wings.
  • a counterweight 14 is movably mounted on an axis 15 along the other wing of the part 12.
  • the stopper 5 is disposed in the opening 2 opposite the parts 4 and the axes 8 and 11 are respectively vertical to the axes 10 and 13; the stopper thus prevents the parts from leaving the oven. It will be noted that, in this position, the center of gravity of the counterweight 14 is substantially vertical to the pivot 13 so that the position of the arm 7, of the connecting rod 9 and of the part 12 is a position of stable equilibrium and , that therefore, the arm 7 with the stopper 5 remains in the position shown.
  • the counterweight 14 is moved to bring it to the end of the second wing of the part 12.
  • the counterweight thus exerts on the part a torque which tends to make it rotate clockwise.
  • This movement has the effect of removing the stopper 5 from the opening 2 and lifting the arm 7 with the stopper ( Figure 2), which clears the passage for the charging of the parts 4.
  • the arm 7 occupies a position for which the torque exerted by the mobile assembly balances that generated by the counterweight 14.
