Definitions

  • the linear vibratory feeder illustrative of the present invention belongs to that class of inline or vibratory feeders such as broadly disclosed in Otto K. SchwenzSpr U.S. Pat. No. 3,322,260.
  • This patented construction has been subsequently modified to provide for coil gap adjustments as disclosed in Floyd E. Smith patent application Ser. No. 792,303 filed Jan. 21, 1969 now abandoned.
  • the basic construction attempts to offset the vibration of the action mass by an equal and opposite vibration of the reaction mass to the end that little or no vibration is transmitted through the base.
  • the gap between the armature and coil is made adjustable. Nevertheless, despite the implementation of Newtons Third Law of Motion, and the adjustability of the coil gap, it has been found that certain harmonic actions occur which are difficult to isolate and neutralize, but which can stimulate the base of the unit in operation with walking-type motion.
  • the present invention stems from the discovery that by positioning both the coil and armature beneath the reaction mass of an inline or linear vibratory feeder of the class referred to above, that the centers of gravity of the action and reaction mass, irrespective of weight, can be rendered substantially coincident in operation. This result is achieved by providing a pair of side plates which are secured in adjustable relationship with the action mass, but which depend therefrom in flanking relationship with the reaction mass.
  • the coil or armature is mounted to the two side plates and adjustably opposes the opposite member which is secured to a portion of the bottom of the reaction mass.
  • the action mass springs are positioned outboard of the reaction mass springs, and the action mass is physically longer than the reaction mass.
  • the result is one of substantially reduced vibration in harmonic motion, and one which will permit several like linear feeders to be secured to a single track, and when operated with a single source of power or control device, operate in substantial uniform action on such a track to make long distance feeding possible.
  • the substantially reduced vibration and potential harmonics in the base further render the unit simple to mount to any host machine and, of course, quieter in operation.
  • FIG. 1 A typical diagrammatic installation of a linear feeder pair is shown in FIG. 1 in which the left and right hand portions show typical machine installations which are connected for the transfer of small parts by means of two vibratories in a single track. The view is in front elevation.
  • FIG. 2 is a front elevation of a typical illustrative vibratory feeder showing in phantom lines a reaction and portions of the action mass.
  • FIG. 3 is a front elevation of an alternative embodiment illustrated similarly to that of FIG. 2 showing the coil and armature reversed.
  • FIG. 4 is a diagrammatic perspective exploded view of the inline feeder illustrative of the present invention.
  • FIG. 5 is an end view illustrative of the inline vibratory feeder showing the track mounted thereon.
  • a pair oflinear vibratory feeders l0 illustrative of the present invention are mounted by means of the mounting holes 40 above supports 12 and operate together with a single track 1 1 to transfer small parts from a first work station 14 to a second work station 15.
  • the particular linear vibratory feeder illustrative of the invention transmits a very low quantum of vibration to a support member, and accordingly supports such as wooden horses can be employed for temporary in-plant tooling to transfer parts from one machine to another without an intermediate hopper.
  • other applications include taking parts from bowl type vibratory feeders, and other transfer operations in the assembly and production of various end products.
  • the track 11 is secured atop the action mass 20.
  • the reaction mass 21 is positioned beneath the action mass 20, and is supported on the base 13 primarily by means of reaction mass springs 24.
  • the action mass 20 is supported atop the base 13 by means of action mass springs 22.
  • the coil 16 is secured by means of coil mounting screws 29 to the side plates 19. Adjustability is achieved through the adjusting screws 25 which secure the side plates 19 by means of adjustment screw slots 26 to the action mass 20.
  • FIG. 4 the single side plate 19 is shown as being removed from attachment to the action mass 20 by means of the adjusting screws 25 which engage the screw slots 26 and f1- nally the threaded mounting holes 27 in the sides of the action mass 20.
  • Threaded track mounting holes 23 are provided on the upper surface of the action mass 20 to secure a wide variety of configurations of tracks 11.
  • the action mass springs 22 are shown as two in number, and separated by means of spring separators 34 at the top and bottom of the action mass springs 22. Keepers 35 are provided on the outboard portion of the action mass springs 22, and the same are all secured in place against the action mass spring mounts 31 by means of the action spring screws 36. A similar mounting is effected at the lower portion of the action mass spring 22 where the same engage the base spring mount 30 which extends upwardly from the base 13 and provides a pair of opposed shoulders at both ends of the unit for the mounting of the action mass springs 22 as well as the reaction mass springs 24. While two action mass springs 22 are shown, more can be used if additional sparators 34 are provided. This requirement of separation is also applicable to the reaction mass springs 24.
  • reaction mass springs 24 are mounted against the reaction mass spring mount 32 by means of the reaction mass keepers 38 and the reaction mass spring mounting screws 39. At the upper end portion of the reaction mass springs 24, similar reaction mass keepers 38 are employed and reaction mass mounting screws 39 are provided to secure the same to the reaction mass spring mount 32. Suitable threaded holes are bored in the spring mount 30 of the base, the action mass spring mount 31, and the reaction mass spring mount 32 to accommodate the respective screws.
  • reaction mass 21 is provided with an armature mount 41 which extends downwardly and to which the armature 18 is secured.
  • a counterweight 42 is provided as an extension of the lower portion of the reaction mass 21.
  • the coil gap between the coil 16 and the armature 18 can be visually observed through the coil gap window 28 and adjusted by means of loosening the adjusting screws 25 and moving the side plates 19 with their associated coil 16 (secured to the side plates by coil mounting screws 29) until the particular gap which is desired has been achieved.
  • the centers of gravity can be worked out by dividing up the silhouette configuration of the action mass 20 and the reaction mass 21 as well as weighing the parts.
  • this can be done by boring holes in the conterweight 42 or the armature mount 41, or alternatively positioning various weights at adjustable stations on both of the side plates 19.
  • the net result is to substantially overlap or render coincident the center of gravity of the action mass 1 and the center of gravity of the reaction mass 2, to the end that in operation substantially all vibration is cancelled out.
  • rendering the action and reaction masses of substantially the same weight is desirable but does not have the same effect as rendering the action and reaction masses substantially coincident.
  • the action mass center of gravity for a production unit is positioned slightly below that of the reaction mass in the anticipation that it will be raised by the track and the contained parts.
  • Such modification can be determined by drawing the reaction and action masses as well as anticipating the weight of the armature and coil, and thereafter breaking the system into small rectangles, trapezoids, triangles and the like and integrating the resultant masses and moments into a single center of gravity. After the initial prototype unit is constructed and proven, the balance point between the reaction masses and the action masses can then be actually tested, and thus the centers of gravity determined empirically, and adjusted by adding or decreasing weight where appropriate.
  • an inline linear vibratory feeder having an action mass for supporting a linear track, a reaction mass for dynamic balance with the action mass, driving means for imparting opposed forces to the action and reaction masses, a base, yieldable means for securing the action and reaction masses to the base with the action mass above the reaction mass, and a pair of side plates secured in parallel flanking relationships to a portion of driving means and one of said masses; the improvement of an organization and proportion of elements to render the centers of gravity of the total action and reaction masses substantially coincident, comprising:
  • said driving means comprising an armature secured to the side plates and beneath the reaction mass, and a coil secured to the reaction mass and there beneath. 4.
  • said driving means comprising a coil secured to the side plates and beneath the reaction mass, and an armature secured to the reaction mass and therebeneath. 5.
  • said means for securing the side plates to the action mass comprising elongate slots whereby the gap between the coil and the armature may be adjusted by shifting the side plate-coil assembly relative to the action mass. 6.
  • said inline feeder of claim 4
  • said means for securing the side plates to the action mass comprising elongate slots whereby the gap between the armature and the coil may be adjusted by shifting the side plate-coil assembly relative to the action mass.
  • reaction mass having a pair of depending opposed members defining a coil clearance area
  • one of said depending members serving as one support for the armature.
  • reaction mass having a pair of depending opposed members defining a coil clearance area
  • one of said depending members serving as one support for the coil.
  • reaction mass center of gravity being above the center of gravity of the action mass by an amount to offset the raising of the action mass center of gravity by the addition of a feeder track.
