Definitions

  • the present invention relates to an automatic machine for the external fettling of ceramic vitreous china articles such as water closet pans, flushing tanks, bidets, wash basins and other similar sanitary appliances in accordance with the pre-characterising part of claim 1.
  • the said fettling operation is known to consist of a sort of surface finishing of the cast articles still in their soft state before they are fed to the other operational stages of the production cycle, such as drying.
  • Cleaning and trimming machines are disclosed in DE-A-1.950.304, corresponding to the pre-characterising part of claim 1, consisting of two shafts supporting swinging radial tools, the said shafts being located at the ends of vertical oscillating frames.
  • Such a type of machine is not well-suited for external fettling of vitreous china articles because it cannot operate on the lateral and upper zones of the article, and furthermore the tools cannot smoothly follow all the external surface of the article and be driven along the shape thereof.
  • the present invention is intended to provide a machine able to obviate the aforesaid drawbacks by automatically effecting the fettling of the articles, by means of a simple, rational and extremely reliable constructional design.
  • the machine according to the invention is proposed in claim 1 and basically comprises a portal carriage to be disposed transversely to a support bench for the articles to be fettled, and autonomously mobile parallel to said bench, on its cross-member there being disposed a series of rotating brushes arranged to make contact with the various zones of the outer surface extension of the articles.
  • said cross-member there are provided two opposing rotating brushes with their shafts vertical, and mobile towards and away from each other, and a third vertically mobile rotating brush with its shaft horizontal, and disposed overhanging the central zone of said cross-member.
  • These brushes comprise a shaft provided with a plurality of radial clamps which each carry a thin strip of SCOTCH BRITE which extends radially when the brush is in motion, but which falls freely downwards when the brush is stationary.
  • FIGS. 1 and 2 show a portal 1 constituted by two facing flat frames 2 ( Figure 3) which are joined together by a convenient set of transverse elements.
  • Said toothed wheels 7 are rotated in the two opposing directions by respective geared motors with an incorporated speed variator 8, which are fixed on the inside of the bases of the uprights of the portal 1.
  • the rails 4 are disposed straddling a support bench 9 on which the articles to be fettled 12 are placed suitably spaced apart, and by way of suitable supports and bases, 10 and 11 respectively.
  • wash basins but the machine according to the invention is also able to fettle other sanitary appliances such as water closet pans, flushing tanks, bidets and urinals.
  • each track 13 With the opposing longitudinal edges of each track 13 there engage two opposing pairs of idle grooved wheels 14 pertaining to a carriage 15 arranged to move along the cross-member of the portal 1 in the two opposing directions.
  • Said carriage 15 is located on one side of said cross-member, and a further similar carriage is disposed on the other side of the same cross-member as can be seen from Figure 1.
  • Each carriage 15 is provided internally with a threaded bush of horizontal axis 16, with which there engages a threaded shaft 17 driven by a respective geared motor 18 which is fixed to the corresponding end of the cross-member of the portal 1.
  • Each carriage 15 comprises, fixed to its central portion, a vertical sleeve 19 in which a drive pin 21 is rotatably mounted by way of suitable rolling bearings 20.
  • the lower projecting end of this pin comprises a joint 23 for fixing the vertical shaft 24 of a brush 25.
  • the vertical shaft 24 comprises a series of equidistant circumferential longitudinal slots 26, with each of which there is associated a plurality of radial clamps.
  • Each clamp comprises a connection plate 27, of which the inner portion, i.e. that which is intended to be inserted into one of the slots 26, is of T configuration.
  • connection plates 27 there is disposed a retention collar 28 arranged to engage the said T-shaped portions, and the entire assembly is clamped into a stack between two suitable end elements, of which one is visible in Figure 3.
  • a thin strip of SCOTCH BRITE 31 is fixed to each connection plate 27 by means of a locking plate 29 and a respective pair of bolts 30.
  • Said strip 31 extends vertically in a flabby condition when the shaft 24 is stationary, whereas when the shaft rotates, the strip extends horizontally as shown in Figures 1 and 2, to rub the corresponding lateral zone of the articles 12.
  • a front bracket 36 of which the free end is provided lowerly with a fork 37 which supports a fettling brush 38 which has its shaft horizontal, and is disposed transversely to the bench 9.
  • the brush 28 which is entirely similar to the brushes 25 heretofore described, is rotated in the two opposing directions by a variable speed motor with an electronic control panel 39.
  • the portal 1 can be fixed or stationary while the articles are moved by means of a conveyor or suitable trollies.
