Definitions

  • a vibrator has an annular material receptacle that is resiliently supported in a substantially horizontal position and rotated about a substantially vertical axis, and an out-of-balance shaft that extends through the receptacle.
  • This invention relates generally to material handling devices and more particularly to an improved vibrator of the type known sometimes as a vibratory mill.
  • Prior art devices in the field to which this invention is directed were comprised of annular work receptacles having semi-circular or rectangular transverse cross sections.
  • the receptacles were vibrated by one or more out of phase, unbalanced masses that were mounted on a drive shaft.
  • the unbalanced masses were secured to the shaft at some distance to the plane of the horizontal center of gravity of the receptacle which was concentric with the axis of the shaft. Examples of this general type of prior art devices are U.S. Patents No. 2,882,024 and 3,100,088.
  • the material in the receptacle was driven along a path conforming to the shape of the receptacle and, in addition, was moved transversely to the annular path.
  • the material actually moved along a helical path that resulted from the combined movements described immediately above.
  • the relative movements of the articles in the receptacle resulted in the grinding or polishing thereof.
  • a further object of this invention is to provide a more compact arrangement of the above mentioned vibrating device.
  • a particular object of this invention is to provide means for imparting a combination of rotary and swinging motions to the articles contained in a vibrating device while at the same time altering the angular velocity of the articles.
  • the present invention broadly provides for an annular work piece receptacle that has a substantially toroidal shape.
  • the two lower quadrants and at least a portion of one of the upper quadrants of the receptacle are curved; the partially curved upper quadrant is provided with an upwardly extending outer wall section; and an inner wall section extends upwardly from the opposite, lower quadrant to define an entrance throat into the receptacle.
  • the receptacle is supported from beneath on springs that extend towards the rotational axis of the receptacle.
  • a hollow support member provides the mounting means for the lower ends of the springs, the upper ends of which are secured to the lower surface of the receptacle.
  • Drive means are provided for rotating the support member about the axis of the receptacle.
  • a motor driven shaft having out-of-balance masses secured thereto, extends through the hollow support means and is rotatably journalled in the receptacle.
  • the articles in the receptacle are thrown outwardly due to centrifugal force.
  • the articles have a gravitational force of their own, however, which force is directed downwardly, the resultant force on the articles is directed downwardly and outwardly.
  • the resultant force thus pro **d is somewhat smaller than the acceleration imparted to the articles due to the swiging motion of the receptacle and the net effect is periodically to alter the magnitude of the resultant force.
  • the magnitude of the centrifugal force depends on the rotational speed of the articles in the receptacle.
  • the swinging motion of the receptacle which is added to the rotational motion of the receptacle causes a variation in the centrifugal force thus creating a loosening or aerating effect on the articles therein.
  • the swinging motion occurs on a closed, curved path which coincides at times with the rotational movement of the articles and is, at other times, opposite thereto.
  • the concave outer wall prevents the articles from being hurled out as the receptacle rotates.
  • the curved cross sectional shape also serves to guide the articles into a revolving movement as a result of the swinging movement of the receptacle. Further, since the curved side walls act to retain the articles during rotation, the upper side of the receptacle may be left open, thus preventing the building of excessive internal pressures and facilitating the loading and unloading of the receptacle.
  • the resilient support therefor permits the addition or summation of the rotational and swinging movements of the receptacle.
  • the resilient support is provided by a plurality of springs which are set at an angle to the rotational axis of the work support and thereby contributes to both the rotating and swinging action of the receptacle which is vibrated by means independent of the drive means for the support member.
  • a feature of this invention is that the entire device may be made very compactly by concentrically surrounding the unbalanced shaft with the annular work piece receptacle.
  • Another constructional feature of the invention is the provision of two out-of-balance masses that are out-of-phase with each other. The lower mass is placed below the horizontal plane of the center of gravity of the work piece receptacle and the upper mass is placed no lower than the horizontal plane of the center of gravity.
  • the axes of the angularly positioned support springs intersect at a point that is no lower than the horizontal plane of the gravity and substantially coincidental with the rotational axis of the annular work piece receptacle.
  • the aforementioned construction transmits the rotary and swinging movement of the receptacle to the contents therein and the articles themselves move with a rotary movement in the cross section of the annular receptacle and a curvilinear movement along the annular receptacle. These two movements occur concurrently and in combination with the periodic change in the angular velocity of the articles in the receptacle.
  • annular work piece receptacle 1 that has a wall 2 which includes a concave outer wall, the largest diameter of which is designated as the horizontal plane x-x.
  • Straight wall sections extend upwardly from the receptacle wall 2 to define a throat therebetween.
  • the receptacle 1 is supported by a plurality of springs 3 that are in a slanted position so that the spring axes intersect substantially at or above the horizontal plane x-x of the center of gravity.
  • the point of intersection is substantially on the axis yy of the annular work piece receptacle 1 at a location determined by the quantity of material in the receptacle.
  • the springs 3 are carried by abutments on a hollow support member 6 that is rotatably journalled about the axis y-y by means of bearings 4 and 5.
  • the support member 6 is driven by a motor 7. Suitable means such as the pulley and belt system illustrated, couple the motor 7 to the support member 6.
  • the drive torque of the motor 7 is transmitted to the work piece receptacle 1 through the support member 6 and the springs 3, so that the receptacle 1 may be resiliently rotated.
  • An out-of-balance shaft is journalled concentrically within the hollow support member 1.
  • the shaft 10 is driven through a flexible coupling 9 by a motor 8.
  • the shaft 10 is rotatably journalled in a downwardly extending portion 13 of the receptacle 1 by means of bearings 11 and 12.
  • the out-of-balance shaft 10 has out-of-balance masses 14 and 15 secured thereto.
  • the out-of-balance masses are axially spaced from each other on the shaft 10 and angularly out-of-phase with each other.
  • the mass 14 is located at a distance below the horizontal plane of the center of gravity which coincides with the x-x plane.
  • the mass 14 may also be positioned as high as the x--x plane.
  • the mass 15, on the other hand, is located substantially at the x-x center of gravity plane or may even be positioned higher than that.
  • the work piece receptacle 1 When the out-of-balance shaft 10 is driven by the motor 8, the work piece receptacle 1 is given a sawtooth oscillation in a well known manner.
  • the rotation of the axis of the out-of-balance shaft '10 forces all points lying thereon to generate a cylindrical path obliquely about the surface of a theoretical hyperboloid.
  • the surfaces follow a circular path in a region free from surfaces bordering the annular space and terminate along the broken line 16.
  • the contents of the work piece receptacle 1 thereby carry out a rotary movement in the annular cross section in the direction of the arrow shown in the drawing.
  • the contents of the receptacle also carry out a forward movement in the annular space. By a combination of these two movements, the contents of the receptacle 1 traverse a screw thread course.
  • the centrifugal force F efiects an increased compression of the articles in the receptacle 1 and therefore an increased mutual influence of the articles on each other. A loosening effect is also maintained by the respective relative movements of the articles, however, due to the limitation .of the extent of the resulting force R.
  • the material in the receptacle acquires a volumetric form which proceeds in the area free from the receptacle wall along the line 17. This results from the simultaneous swinging and rotary movements of the receptacle 1 and the maintenance of the screw thread course in the circular direction of the direction of the annular receptacle 1.
  • a portion of the curved swinging motion is in the direction of the rotation of the receptacle, while the remaining portion of each cycle of curved swinging motion is opposite to the direction of receptacle rotation.
  • the swinging motion of the receptacle 1 occurs on closed, curved paths, there results from these opposed motions a receptacle rotation with periodically varying angular velocity. This change of angular direction of the receptacle further increases the intensive relative movements of the articles in the receptacle.
  • a vibrator for use in vibrating material, compris- (a) an annular receptacle adapted to receive and to hold material to he vibrated;
  • a rotatable upright shaft having means applying an unbalanced force to said receptacle during the rotation thereof in such a manner that the resultant force applied to the material by the combined centrifugal and gravitational forces due to the rotation of the receptacle is smaller than the accelerating force of the swinging movement which periodically falls in the direction opposite to that of said resultant force.
  • a vibrator in accordance with claim 1, wherein said means applying an unbalanced force is comprised of at least two masses secured to said upright shaft, said masses being axially spaced on said shaft and angularly ofi-set from each other.
