Definitions

  • the present invention relates to the field of sorting parts of different shapes and dimensions, in particular plastic injection parts, and relates to a sorting device suitable for this purpose.
  • the core is like the injection channel of the different types of molds and allows the feeding of the impressions.
  • This core is therefore very variable in shape and size so that its separation, by sorting, of the molding parts is very difficult to achieve.
  • the elements of large size are separated by means of spiral or pallet rollers or vibrating tables from the elements of small size, which are evacuated by gravity, taking into account the inclination of the reception table. sorters, or by free fall after passage between the means of separation of the elements of large size. The latter can thus be brought to a receiving receptacle, to a table, or to a conveyor belt.
  • a coin sorting device constituted by a cylindrical receptacle for receiving the elements to be separated, having an opening in its vertical wall and by a conical element disposed in the cylindrical receptacle, forming the movable base. of the latter and rotated.
  • this known device it is, however, not possible to make an adjustment of the spacing between the wall of the receptacle for receiving the elements and the movable bottom of this receptacle, so that a sort of elements of different dimensions not possible.
  • the present invention aims to overcome these drawbacks.
  • a device for sorting parts in particular parts of different shapes and sizes, essentially constituted by a cylindrical receptacle for receiving the elements to be separated having an opening in its vertical wall and by a conical element forming the movable bottom of the latter and driven in rotation, characterized in that the conical element is disposed under the cylindrical receptacle and is provided with means for adjusting the spacing between the conical element and the lower part of the wall of the cylindrical receptacle.
  • the device for sorting parts in particular parts of different shapes and dimensions, essentially consists of a cylindrical receptacle 1 for receiving the elements to be separated having an opening 2 in its vertical wall, by a conical element 3 placed under the cylindrical receptacle 1, forming the movable bottom of the latter, and driven in rotation and by a means 4 for adjusting the spacing between the conical element 3 and the lower part of the wall of the cylindrical receptacle 1.
  • the cylindrical receptacle 1 is advantageously in the form of a vertical wall extending along a portion of a circle and the opening 2 of which is delimited at one end by a second vertical wall 5 perpendicular to the tangent passing through the first and intended to retain parts spilled from the mold.
  • this second vertical wall 5 is disposed on the side for introducing the pieces to be sorted, which is opposite to that for rejecting the pieces of large size which are ejected by the conical element 3 during its rotation.
  • the conical element 3, placed under the cylindrical receptacle 1, is rotated by means of a friction clutch 6 and of a geared motor assembly 7 or of a direct current motor fitted with a variator mounted, preferably on the support axis 8 of the conical element 3.
  • the latter advantageously has grooves, ridges or slight undulations 24 according to its generatrices, these grooves, ridges or undulations extending inside the perimeter delimited by the receptacle 1 ( Figures 1 and 2).
  • the large-sized parts taken between the large surface of the conical element 3 and the lower part of the cylindrical receptacle 1, are, first of all, wedged between the two surfaces and, therefore, then put into rotation , so that there is a mixing of the parts contained in the receptacle 1 resulting in their separation and natural elimination by gravity of the small parts.
  • the means 4 for adjusting the spacing between the conical element 3 and the lower part of the wall of the cylindrical receptacle 1 is constituted by a support bearing 9 secured to the external face of the wall of the cylindrical receptacle 1 and provided with a blind housing 10 cooperating with a vertical guide means 11 in the form of an axis and by a threaded rod 12 penetrating into said vertical guide means 11, this rod 12 being provided with a device 13 for actuation in rotation in the form a knurled button or a crank pressing on the external face of the housing 10 and being held in said housing 10 by means of a shoulder 14 or an attached ring.
  • the mounting of the threaded rod 12 in the closure wall of the housing 10 is of a type known in the art and does not require any additional description. With this means 4, it is possible to make a fine adjustment of the spacing between the lower part of the wall of the cylindrical receptacle 1 and the surface of the conical element 3, allowing perfect sorting of the parts to be separated.
  • the lower part of the wall of the cylindrical receptacle 1 is advantageously provided with a flap 15 of frustoconical shape, extending towards the outside of the receptacle 1, parallel to the conical element 3.
  • This flap 15 is intended to retain large parts template during the rotation of element 3 and to avoid their accidental passage simultaneously with that of small parts.
  • Figures 3 and 4 of the accompanying drawings show an alternative embodiment of the invention in which the device comprises two cylindrical receptacles 16 and 17 for receiving the elements or parts to be separated having different diameters and mounted concentrically, on the one hand, to the conical element 3 ′ and, on the other hand, between them, these receptacles 16 and 17 being provided with a common retaining plate 18 extending radially and closing the discharge zone and the cylindrical receptacle 17 of larger diameter being provided with a movable inclined wall 19 for retaining and discharging sorted parts cooperating with a clearance 20 provided for this purpose in the wall of the receptacle 17.
  • the receptacles 16 and 17 are adjustable vertically with respect to the conical element 3 ′ by means of guide and adjustment devices with screws 21 cooperating with a support 22.
  • the adjustment devices 21 are comparable to means 4 of the device according to the figures 1 and 2 and are not described in more detail. These devices therefore also allow a variation in the spacing of the lower part of the wall of the receptacles 16 and 17, in particular of their flap 15 ′ and 15 ⁇ , depending on the parts or elements to be separated.
  • the movable inclined wall 19 for retaining and discharging sorted parts is advantageously fixed to a slide 23 mounted adjustable in position on the wall of the receptacle 17 by means of screws.
  • the drive of the conical element 3 ′ can be carried out in the same manner as for the aforementioned conical element 3.
  • the device according to Figures 3 and 4 allows the separation of parts having three different sizes. Indeed, the parts poured into the receptacle 16 can undergo a first separation during which the larger pieces are discharged through the opening of the wall of said receptacle, fall on the movable inclined wall 19 which directs them to a receiving tank.
  • the parts of medium and small sizes can cross the space delimited between the flap 15 ′ of the wall of the receptacle 16 and the conical element 3 ′ to arrive in the receptacle 17, in which the parts of smaller size cross the space between the flap 15 ⁇ of the wall of the receptacle 17 and the conical element 3 ′, to be collected in a receiving tank, while the pieces of medium size, which cannot pass through this space, are scraped by the movable inclined wall 19 and pass through the clearance 20 provided for this purpose in the wall of the receptacle 17.
  • the vertical wall 5, the common retaining plate 18 and the movable inclined wall 19 are advantageously provided, on their side facing the conical element 3 or 3 ′, with a flexible strip 24 cooperating with the surface of said conical element 3 or 3 ′, thus allowing the passage of grooves, ridges or slight undulations 24, provided on the surface of the latter.
  • the device according to the invention can be placed directly under a mold or at the end of a carpet or sorting table, the parts or elements to be sorted being poured into an area close to the vertical retaining wall.
  • the shape of the cone causes permanent instability of the parts or elements which are poured into the device, which results in rapid evacuation of the elements or parts of small size, while those of large size are evacuated during the rotation of the conical element 3.
  • the device according to the invention can be used, due to its autonomy and its small size, both in a fixed position near an injection press, and directly in such a press where it will act as a receiver pieces and carrots.
