Definitions

  • the present invention relates generally to the processing of discrete articles, and more particularly to the polishing of dis crete articles. Still more specifically, the present invention relates to a method of removing particulate contaminants from the surfaces
  • the present invention has as its general object to overcome the aforementioned disadvantages.
  • More particularly the present invention has as its object to provide an improved method of polishing the surfaces of discrete articles.
  • An additional object of the invention is to provide an apparatus capable of carrying the novel method into effect.
  • a concomitant object of the invention is to provide such an apparatus which is relatively small in its dimensions, but is very simple in construction and therefore highly reliable.
  • Still another object of the invention is to provide such an apparatus which effects proper cleaning and polishing of the surfaces of the discrete articles with a single pass-through of the articles through the apparatus.
  • Still another object of the invention is to provide such an apparatus which requires only infrequent exchange of the polishing and cleaning elements.
  • one feature of the invention resides in a method of cleaning and polishing the surfaces of discrete articles for removing particulate contaminants therefrom.
  • This method comprises the steps of advancing the articles in a predetermined path toward and beyond the processing station, and subjecting the articles to the influence of suction while they are in this path and thereby remove loose particulate contaminants. Finally, the articles are subjected at the processing station to a brushing action to thereby loosen particulate contaminants which adhere to the surfaces of the articles, for removal of such contaminants by the prevailing suction.
  • FIG. 1 is a somewhat diagrammatic front view of an apparatus according to the present invention.
  • FIG. 2 is a partially sectioned view of the apparatus of FIG. 1, on an enlarged scale.
  • the novel apparatus in accordance with our invention comprises a brushlike first disk-shaped contact element 1 and a second hollow contact element 2 which is also disk shaped, with the elements 1 and 2 being juxtaposed with one another.
  • the element 1 is located above the element 2 and mounted on a hollow shaft 3 which is in turn suitably mounted in a nonillustrated machine frame and whose upper open end communicates with the hopper 4.
  • the lower open end of the shaft 3 is open at the center of the brushlike element 1 so that discrete articles which pass through the hopper 4 and the shaft 2, enter into space between the juxtaposed surfaces of the elements 1 and 2, as evident from FIG. 2.
  • the rotation is carried out in such a manner that the shaft 3, and thereby the element 1, rotate alternately in opposite directions.
  • the shaft 3 will rotate first in one direction and then will rotate in the opposite direction, to thereupon again rotate in the one direction. How this is accomplished is well known in the art and requires no detailed discussion herein.
  • the drive for effecting this is not a part of the present invention.
  • the hollow shaft 3 further carries a cam disk 7 with which a roller 8 is associated which is rotatably secured on a stationary holder member 9.
  • a pressure spring 10 is located below the cam disk 7 surrounding a portion of the hollow shaft 3 and abutting against the hub 11 of a tilting lever carrying the entire device.
  • the lower axial end face of the hub II is constructed as a cam track 12 on which a roller 13 rolls.
  • the roller 13 in turn is rotatably secured in a holder 14 which is secured in turn on the hollow shaft 3 carrying the element 1. It will be evident that with this arrangement the element 1 is tilted or laterally shifted, a movement which is superimposed upon its rotation, and that additionally has superimposed upon the two movements a further third movement in direction towards and away from the upper surface of the element 2.
  • the element 2 has an upper wall 15 which is provided with sievelike perforations 16.
  • the exposed surface of the wall 15 is covered, as evident from FIG. 2, with an airand dust-permeable fabric cover 18 of suitable material, the term fabric here applying not only to textiles but to other suitable materials. It is also possible to use other types of covers, for instance consisting of nylon or the like, as long as they are air and dust permeable so that dustlike powder removed from the discrete articles 17, that is the capsules, can be drawn therethrough.
  • a funnel-shaped housing 21 surrounds at least the element 2 and, because it is larger in diameter than the element 2, the latter is secured in position by spacing members 22 which con nect it with the funnel-shaped housing 21.
  • the housing tapers downwardly away from the element 2 which latter is provided with a suction aperture 19 at its bottom which is located so as to be coaxial with the hollow shaft 3.
  • a conduit 20 connects the suction opening 19 with the diagrammatically illustrated suction means.
  • the bottom region of the housing 21 is provided with an outlet opening 23 which faces upwardly towards the element 2 so that cleaned capsules 17 which tumble over the edge of the element 2 as shown in FIG. 2, will fall into this outlet opening 23 to be convered away thereby into a collecting container 26.
  • Proximal to the outlet opening 23 is an aperture 24 facing transversely to the direction of downward movement of the capsules l7, and the aperture 24 is connected via a conduit 25 with the suction means S.
  • capsules 17 introduced into the hopper 4 pass through the hollow shaft 3 and enter through the open outlet end of the hollow shaft 3, and the corresponding aperture in the element 1 which is provided at the center of the element 1 and free from bristles, so as to become deposited on the cover 18 of the upper wall of the element 2. Because of the up and down movement of the element 1, combined with the rotary movement thereof in alternately opposite directions and the tilting or lateral movement of the element 1, these capsules 17 are moved from the center of the elements 1 and 2 in radially outward direction to the edge of the element 2 and then tumbled over this edge to fall in the housing 21 through the outlet opening 23 thereof into the receptacle 26.
  • the movement of the element I results in contacting of the entire surface of the capsules 17 by the bristles of the element 1 in such a manner than an excellent cleaning and polishing effect is obtained, removing adhering particulate contaminants from these surfaces.
  • the suction aperture 19 is located directly below the outlet opening of the hollow shaft 3, any particulate contaminants which loosely adhere to the surfaces of the capsules 17 are withdrawn even as the capsules approach the elements 1 and 2, that is before they undergo treatment by the same.
  • the suction is of course stronger at the center of the element 2 than towards the edges thereof. As a result it is necessary only to remove the more strongly adhering particulate contaminants from the surfaces of the capsules 17 by contact with the bristles of the element 1 and the cover 18 ofthe element 2.
  • the composite movement of the element 1 provides for excellent cleaning of the capsules over their entire surfaces, including their end faces if they are elongated.
  • the element 1 it should be understood that it is not absolutely essential for the element 1 to be constructed as a brushlike element with bristles, because other solutions are also possible. It is also not to be considered limiting that in the illustrated embodiment the element 2 is constructed so as to be stationary. However, in this particular construction, and by cooperation of the bristles of the element 1 with the fabric cover 18 of the element 2 the particulate contaminants removed from the surfaces of the capsules 17 is prevented from adhering to the bristles of the element 1 and is forced to fall out between the bristles so that it can be removed by the prevailing suction. As a result of this the brushlike element 1 need be removed only infrequently for cleaning purposes.
  • the airand dust-permeable cover 18 assures that the capsules will not be scratched during their movement while they are being processed, and on the other hand it makes it possible to have a single upper wall 15 with openings of one predetermined size, rather than necessitating the provision of exchangeable separate upper walls with openings of different sizes to accommodate differently dimensioned articles.
  • the suction aperture 24 which is provided proximal to the outlet opening 23 of the housing 21 serves to withdraw such pulverulent matter as may possibly issue from cracked or opened capsules, that is such capsules which might be cracked or opened during the polishing process, and to prevent it from entering into the receptacle 26 where it would again contaminate the already cleaned capsules 17.
  • this is merely an added safety factor because ordinarily any such pulverulent contaminants will be removed by suction through the apertures in the wall 15 and through the cover 18.
  • the suction exerted through the suction aperture 24 serves to withdraw empty half-capsules which might have become emptied when their contents escaped, or capsules which inadvertently were not filled at all, from the cleaned capsules which pass through the outlet opening 23 in the receptacle 26.
  • the present invention provides for rapid and effective cleaning and polishing of the surfaces of discrete articles, of which the capsules 17 are merely representative, in a simple. effective and inexpensive manner without requiring significant technological expenditures for the construction of the machine and without requiring much personal supervision.
  • the elements 1 in the different apparatuses may be provided with different bristles or the like, and/or the elements 2 may be provided with covers 18 of different materials, different weave, mesh or the like.
  • An apparatus for cleaning and polishing the surfaces of discrete articles for removing particulate contaminants therefrom comprising feed means for feeding the discrete articles in a predetermined path; processing means interposed in said path for subjecting the advancing articles to a brushing action so as to loosen particulate contaminants adhering to the surfaces of said articles, said processing means comprising hollow shaft means surrounding a portion of said predetermined path and having an inlet communicating with said feed means, a pair of superimposed disk-shaped elements extending transversely of the longitudinal axis of said hollow shaft means and forming with one another a gap therebetween defining another portion of said path, an outlet opening in said hollow shaft means communicating through the central region of one of said elements with the central region of said gap, bristles provided on one of said elements and extending across said gap in the direction towards the other element; moving means for effecting movement of at least one of said elements with reference to the other, said movement being at least in part rotational about the longitudinal axis of said hollow shaft means; and suction means communicating with said gap so as to remove
