Definitions

  • the present invention relates to apparatus for the knockdown of pieces obtained by the technique of casting and for the separation of risers and the like from such pieces.
  • the object of the present invention is to provide automatically-operating apparatus for the knockdown and the immediate subsequent separation and removal of the useful pieces from the parts detached therefrom so as to achieve the detachment of the risers and other parts progressively and without jamming, even for useful pieces of complex form, devoid of smoothness, and hence without damage to the useful pieces themselves.
  • apparatus for the knockdown and successive selective separation of the useful pieces from the detached parts which consists, according to the present invention, of a support frame supporting a rotary barrel of elongate form, having an open end for the introduction of the pieces to be worked and the other end being closable by a bottom lid which is movable and arrestable at predetermined distances from the mouth of the barrel, so as to create apertures of different widths for the selective discharge by gravity of the waste pieces and the useful pieces in dependence on their shape or size, in correspondence with the said mouth,with the movable lid there being provided a chute conveyor with several directions of discharge, oscillatable so as to convey, by changing its position and hence its direction of discharge, the useful pieces and the waste pieces arriving from the barrel onto separate collecting slides, there being further provided for the programmed control of the loading and rotation of the barrel, the translational movement of the lid and the change of position of the balance chute, pneumatic, electrical or like drive means of known type all connected to a single central control unit.
  • the said barrel is mounted - on a support frame with its longitudinal axis preferably inclined towards the bottom with the movable lid, means for allowing the variation of the said inclination as necessary being associated with the support frame.
  • a scoop or bucket elevating device is provided for loading the barrel at predetermined time intervals, the device being guided for vertical movement and shaped so as to enter partially into the open end of the barrel to discharge the pieces to be treated into the latter.
  • the apparatus of the present invention is constituted by a support framework 1, of metal sections, at the top of which is located a frame 2, also of metal sections, arranged to support for rotation a barrel 3 with its axis horizontal.
  • the frame 2 is pivotally mounted at 4 on two rear pillars of the support framework 1 and, at its opposite end, is fixed to the front pillars of the framework 1 so as to be adjustable by means of two rods or plates 5, each of which is provided with an elongate slot 6 and is pivotally connected, at one end to the frame 2; in each slot 6 is inserted a screw-threaded bolt or the like 7, fixed to the front pillars of the framework 1, and arranged to allow the locking of the rods 5 at a desired position and hence to allow the achievement of different inclinations of the frame 2(and hence also of the barrel 3) with respect to the horizontal plane.
  • the rotatable barrel 3 is cylindrical, in the form shown in the drawings, with a rear open end 8, to allow the loading of the pieces 4 for.knockdown, and with the opposite end closed by a movable lid 9, mounted for axial movement away from the mouth of the barrel 3 by means, and for the reasons, which will be explained below.
  • the barrel 3 is rotatably mounted on the inclinable frame 2 by means of pairs of driving rollers 10-11 (one pair on each longitudinal side of the frame 2); the rollers of each pair are connected to each other by a transmission shaft 12 and are mounted idly on support lugs 13-14 fixed to each longitudinal side of the frame 2.
  • a motor 15 and a chain and gear transmission, generally indicated 16 in the drawings, are provided for rotating at least one pair of the rollers 10-11 whereby these latter rotate the barrel 3 by friction.
  • the barrel may also have longitudinal raised ribs 17-18 etc. on its internal surface for the known-function of improving and/or accelerating the detachment of the waste parts from the usable pieces.
  • the movable bottom or lid 9 is mounted for axial translational movement relative to the mouth of the barrel 3 by means of an actuator device 19, operated by compressed air or the like, slidably mounted on a box support body 20 by means of a guide plate 21.
  • the opening movements of the lid 9 are arrested by stops at distances which are predetermined in dependence on the shape or size of the pieces to be discharged separately from each other.
  • the lid, 9 is constituted by a disc-shaped body 22 forming the sealing means for mating with the edge of the barrel 3, to which disc body is fixed a cylinder 23 of smaller diameter than that of the interior of the barrel and peripherally provided with ribs or longitudinal projections 24-25 etc., equidistant from each other and arranged to form separate passages between each pair of ribs and the internal edge of the mouth of the barrel the passages being of substantially labyrinthine form and variable width according to the degree of opening of the lid 9.
  • a chute body 26 pivotally mounted on pins 27 supported by two opposite support plates 28.
  • the chute 26 is made to oscillate about the pins 27 by a piston 27 operated by compressed air or hydraulically, which drives a crank 30 connected to a wall of the chute 26 or acts at the axis of rotation of the chute itself.
  • the piston 29 can make the chute 26 oscillate so as to lower one or other of its opposite discharge ends alternately and hence allow the discharge of the product coming from the barrel 3 in two different directions, specifically onto two separate chutes 31 and 32.
  • the chute 31 has a sieve bottom 33, with two collecting ducts 34 and 35 the first of which allows the discharge of the waste products of smaller size and the other the remaining pieces.
  • the sieve chute 31 is provided with a vibratory drive 36 which, if required, can vibrate the sieve 31 to facilitate the sieving and separation of the products during their passage along the chute 31 itself.
  • the apparatus is provided with a loading device, constituted by a chute or scoop 37, connected in orientable or oscillating manner to. a cross member 38 which is mounted for vertical movement along two opposite uprights 39-40 by means of end rollers guided within guide rails formed along the internal faces of the uprights 39-40.
  • the raising - and lowering of the chute 37 is achieved by means of a geared rotor 41 with a pulley which drives a chain 42 connected to the cross member 38.
  • the inclination of the chute, loaded with products, in correspondence with the open loading mouth of the barrel is achieved by suitable known means not shown.
  • a trap or pit 43 may be provided in the plane on which the apparatus rests and into which the chute can descend down to the level of the said plane.
  • the knockdown operation occurs, as stated above, by the impact of the bodies introduced into the barrel due to the rotation thereof and, as the pieces become detached, as a result of the inclination of the barrel 3, the pieces will tend to move towards the lower end of the barrel where, if the lid 9 is slightly removed, ( Figure 2), the ribs 24-25 etc., will form, together with the lid, a sieve and allow the passage of the desired pieces only, retaining all the other pieces within the barrel.
  • Figure 2 shows the apparatus with the lid 9 slightly open whereby the pieces are discharged onto the chute 32
  • Figure 3 shows the position of discharge of the products of larger size by means'of the chute 31, with the oscillating chute inclined towards the chute 31 itself.
  • the vibratory sieve 31 allows this separation to be effected.
  • the loading of the apparatus may also be made., as well as with the scoop 37, also by other means such as continuous belt conveyors, in which case it will be possible to feed two similar knockdown apparatuses alternately.
  • the barrel may be formed with a polygonal, oval or other cross section
  • the drive system for the oscillating chute may be achieved by other, analogous means
  • the lid may also be perfectly flat, hemi-spherical or differently shaped.
