Definitions

  • the invention relates to mixing of materials, for example, proportioning of a small quantity of one material into a proportioned major quantity of one or more other materials.
  • an apparatus for delivering to a receiver a mixture in predetermined proportions of particulate materials comprising:
  • metering means adapted at each actuation thereof to feed a measured quantity of each material from the respective source to the mixing device
  • the mixing device comprising a cylinder and a rotary mixer blade therein, the cylinder having an opening in its wall and being rotatable about its axis between a first position in which the opening is disposed to receive the measured quantities of materials from the metering means and a second position in which the opening is disposed to deliver the materials to the receiver;
  • FIG. 1 is a sectional elevation of one form of apparatus in accordance with the invention.
  • FIG. 2 shows in two alternative operating positions part of the apparatus shown in FIG. 1;
  • FIGS. 3 and 4 show parts of the apparatus of FIG. 1 in different positions of operation
  • FIG. 5, comprising 5A and 5B, are top and side views, respectively, of the drive means.
  • the apparatus of FIG. 1 includes two side-by-side supply hoppers l, constituting sources of two particualte materials.
  • a metering device is located below each hopper 1, and comprises a rotary cylinder 2 and associated stator flanges 3 and is connected via rotating shafts (FIG. 5) to drive means for the apparatus.
  • Each cylinder has an opening 4 in its wall and the opening communicates with a measuring chamber 5.
  • Preferably at least one of the chambers 5 is of adjustable volume; conveniently by means of an adjustable screw 6, as shown for the left hand chamber.
  • a mixer 7 is mounted below the metering devices.
  • the mixer comprises a stationary cylindrical housing 8 in which fits a rotatable cylinder 9.
  • the housing 8 is formed with openings and flanges which define an inlet 10 and an outlet 11.
  • the cylinder 9 has a longitudinal slot in its wall and a rotary mixing blade 12 is mounted coaxially on a rotatable shaft (FIG. 5) in the drive means within it.
  • the drive means is a conventional assembly including a motor and gears for rotating drive shafts and the components connected thereto.
  • a receiver 13 is mounted below the mixer 7 and is connected to the inlet 14 of an injection molding machine 15.
  • the reciever 13 is mounted on a fulcrum 16 (FIG. 2), so that it can pivot between the two positions A and B shown in FIG. 2.
  • the receiver is so asymmetrically shaped about the vertical plane through its pivot axis that it will tip from position A to position B when the level of the material therein falls sufficiently and will tip in the reverse direction when the level rises sufficiently.
  • a microswitch 17, located in the path of movement of the receiver 13, is adapted to make or break a circuit controlling drive means for the metering devices and the mixer 7.
  • the receiver 13 When the receiver 13 contains more than a predetermined minimum quantity of the materials, it is in position A, so that the drive means are not energized and the metering devices and the mixer 7 are stationary; when the contents of the receiver fall to the predetermined minimum the changed position of the center of gravity causes the receiver 13 to move from position A to position B and this movement actuates the microswitch 17 to complete a circuit for energizing the drive means of the metering devices and the mixer 7. A fresh supply of premixed material is then delivered to the receiver 13 until the quantity of material therein rises to a predetermined maximum, whereupon the changed position of the center of gravity causes it to move from position B to position A and this actuates the microswitch 17 to break the circuit and de-energize the drive means.
  • the materials are plastics powders and/or granules dosed with a coloring agent, the coloring agent being in one supply hopper and the plastics material in another.
  • Apparatus for delivering to a receiver a mixture in predetermined proportions of particulate materials comprising:
  • metering means adapted at each actuation thereof to feed a measured quantity of each material from the respective source to the mixing device
  • the mixing device comprising a cylinder and a rotary mixer blade therein, the cylinder having an opening in its wall and being rotatable about its axis between a first position in which the opening is disposed adjacent said metering means to receive the measured quantities of materials from the metering means and a second position in which the opening is disposed adjacent said receiver to deliver the materials thereto;
  • the metering means comprises for each of the materials a cylinder having in its wall an opening communicating with a measuring chamber in the cylinder, the cylinder being rotatable about its axis between a position in which the opening is disposed to receive sufficient material from the respective source to fill the measuring chamber and a position in which the opening is positioned to deliver the material in the measuring chamber to the mixing device the drive means being effective to rotate the cylinders of the metering means and of the mixing device in synchronism with one another.
  • Apparatus according to claim 1 including means for automatically energizing the drive means when the quantity of material in the receiver falls to a predetermined minimum and for automatically interrupting such energization when the said quantity to a predetermined maximum.
  • Apparatus according to claim 4 in which the receiver is mounted for tipping movement about a horizontal axis and is so asymmetrically shaped about the vertical plane through that axis that it will tip in one direction when the level of the material therein falls sufficiently and in the reverse direction when the level rises sufficiently, such tipping movements of the receiver being arranged to cause energization and deenergization respectively of the drive means.
