Definitions

  • the present invention relates to a vibrating machine for the mass drying of metallic bodies, with automatic unloading of the dried parts.
  • vibrating machines are currently commercially available which are predominantly used for drying metallic parts and comprise a tank body provided with vibrating means and associated with a supporting frame through the interposition of anti-vibration means.
  • a circular bottom is provided inside the tank body and has a ramp-like portion which conveys the items being processed together with the loose material, which can be constituted by abrasive elements, polishing elements and drying elements, to a selection plane which has an initial fixed portion, which in practice separates the parts being processed from the loose material, and an openable central portion which can be connected to a terminal unloading portion.
  • the openable central portion is in practice constituted by a grid which is pivoted, at the edge which is contiguous to the terminal portion to be moved, to a raised position which allows the parts being processed to fall inside the tank.
  • the central portion or grid is arranged so as to continue the fixed initial portion, consequently conveying the parts outward.
  • the aim of the invention is to solve the above described problem by providing a vibrating machine for the mass drying of metallic bodies which allows the unloading steps to be carried out automatically, since the presence of the operator is not required even in the step of passage from the operative condition with recycling to the unloading condition.
  • the vibrating machine should allow to move the openable central portion without running the risk in any way of clamping or trapping parts being processed, during the various operative steps of passage from one working condition to another and to achieve the automation with extremely simple means which are easy to use.
  • Not least object of the present invention is to provide a vibrating machine which can be easily obtained starting from commonly commercially available elements and materials and which is furthermore competitive from a merely economical point of view.
  • a vibrating machine for the mass drying of metallic bodies, with automatic unloading of the dried parts, according to the invention, which comprises a tank body provided with vibrating means and associated with a supporting frame by means of the interposition of anti-vibration means, said tank body having, on the inside, a bottom defining a ramp-shaped portion leading to a selection plane having an initial fixed portion, an openable central portion and a terminal unloading portion, characterized in that said openable central portion comprises a first wing pivoted to said initial fixed portion and a second wing hinged to said terminal unloading portion, said wings being rotatable to place them in a working position, whereat said first wing is rotated downward for causing material to fall into said tank body, and in an unloading position, whereat said first wing and said second wing are mutually aligned for outwardly conveying dried parts.
  • the vibrating machine for the mass drying of metallic bodies, with automatic unloading of the dried parts comprises a tank body generally indicated by the reference numeral 1 which is provided with vibrating means and is associated with a base supporting frame 2 with the interposition of conventional anti-vibration means which are not described herein in detail.
  • the tank body 1 internally defines a bottom 3 with a substantially circular extension which has a ramp-like portion 4 leading into a selection plane generally indicated by the reference numeral 10.
  • Said selection plane 10 is provided with an initial portion 11, advantageously of the grid-shaped kind, which is arranged above electric heating resistors 12 which have the function of heating and drying the grit or loose material which is intermixed between the various parts being processed.
  • the peculiarity of the invention is constituted by the fact that the central openable portion 13 is constituted by a first wing 20 with a grid-shaped configuration, which is pivoted at the edge contiguous to the initial portion 11, and by a second wing 21 which is in turn pivoted at the edge contiguous to the terminal portion 14.
  • the first wing has a width, in the direction of passage of the material, which is smaller than the second wing 21.
  • the wings 20 and 21 are rotatable about their pivoting axis to assume different positions for the passage from the working position to the unloading position and vice versa.
  • the rotation of the wings 20 and 21 is advantageously performed by means of a first and second cylinder, respectively indicated at 22 and 23, which act on the pivoting pin and perform the rotation.
  • the first wing 20 in the working position, i.e., in the position in which the various parts are continuously re-inserted into the tank, the first wing 20 is in a lowered position, i.e., directed towards the bottom of the tank, whereas the second wing 21 is in raised position, i.e., directed upwardly.
  • the material carried by the vibration onto the selection plane creates a first selection with separation of the grit and loose material which falls onto the electric resistors 12, whereas the various parts being machined, indicated by the reference numeral 15, are re-inserted toward the bottom of the tank.
  • the first wing is first rotated upward (figure 5), thus creating a temporary barrier for the passage of the parts being processed, which are thus retained.
  • the second wing 21 is simultaneously rotated downward until it engages a stop abutment 30; the second wing 22 moves to align with the terminal portion 14.
  • the first wing 20 is rotated downward and becomes arranged in alignment with the second wing, thus defining a continuous selection plane (figure 7) which allows the outward unloading of the parts.
  • first wing and the second wing are provided, at the edges of mutual contact, with opposite shaped portions, indicated by the reference numerals 31 and 32, which allow to provide a rabbet-like coupling, with the first wing in practice resting on the edge of the second wing.
  • the first wing is rotated upward, thus releasing the second wing, which is rotatable upward, whereas the first wing is rotated downward, thus returning to the working conditions illustrated in figure 4.
  • the invention achieves the proposed aim and objects; in particular, the fact is stressed that the substantial splitting in two of the openable central portion of the selection plane allows to completely automate the operation of the vibrating machine which can be time-controlled, so as to perform the process for a certain presettable time period and then automatically perform the step of unloading the dried parts without running the risk of trapping the parts during the movement of the openable central portion.
  • the presence of the related abutment wings provided on the coupling edges of the wings 20 and 21 allows to provide a precise rest position for the first wing on the second wing which ensures the continuity of the selection plane so as to achieve easy unloading of the product toward the outside of the machine.
  • the materials employed may be any according to the requirements.
