Definitions

  • This invention relates in general to devices for collecting and discharging cuttings (chips, turnings, borings, etc.) from machine tools, and more particularly to improvements in devices of this character which comprise means whereby the conveyor chain (to which, as known, a reciprocating movement is imparted) can pass from a horizontal position to an inclined position with a view to facilitate the discharge of the cuttings to the outside.
  • the improvements constituting the subject-matter of this invention consist essentially in dividing the tube constituting the cuttings driving member into separate sections hingedly interconnected by links pivotally attached thereto.
  • the guide tube disposed inside the tubular driving sections may be curved to the desired radius to pass from a horizontal position to an inclined position and the driving tube sections may thus pivot to accommodate the curvature of the guide member. This arrangement is used preferably in those portions of the conveyor where a bend is contemplated.
  • FIGURE 1 is a section taken across the longitudinal axis of a collector channel for discharging cuttings, which shows the arrangement of the conveyor chain of this invention
  • FIGURE 2 is a cross sectional view showing the relative arrangement of the channel, guide section and conveyor tube, and
  • FIGURE 3 is a part-sectional view showing the assembly of a tubular driving member with the linkinterconmeeting the successive tubular sections.
  • the channel or chute 1 along which the cuttings (not shown) are to be conveyed has a suitable cross-sectional contour.
  • a guide section 2 mounted in and rigid with this channel is a guide section 2 supported by md welded on a vertical flat iron 3.
  • this flat iron 3 has its lower edge welded edgewise on a relatively wide strip 4 secured in the bottom of the discharge channel 1.
  • Straddling the guide section 2 are a plurality of split tubular sections 5 clearly shown in FIG. 2, these sections having the edges of their lower slot 6 disposed on either side of the vertical flat iron 3.
  • the tubular sections 5 are hingedly interconnected in a vertical plane by means of links 7 pivotally mounted on lugs 8 welded on the ends of these sections 5, as shown.
  • each tubular section 5 is provided with a depending V-shaped stem or bow 12 and with an upper spur 13, according to the known arrangement for carrying along the cuttings.
  • the V-shaped stems or bows 12 serve principally to carry along, in the direction of the opening of the V, the cuttings or like waste materials having a small length and such that generally fall to the bottom of channel 1, whereas the spurs 13 principally serve to carry along in the same direction, that is, to the right of FIG. 1, the cuttings of greater length which are apt to remain above the mobile assembly in the collecting channel.
  • this guide section 2 may be given any desired contour to pass from a horizontal channel to an inclined channel in order to facilitate the discharge of the cuttings to the outside.
  • this arrangement comprising hingedly interconnected chain sections, can only be used in a bent portion of the chain.
  • the length of the tubular sections 5 and the play left between the guide 2 and sections 5 depend on the radius of curvature of the collection channel.
  • Conveyor means for cuttings and similar waste materials comprising a collecting channel having a curved portion including a horizontal portion which has a radius of curvature bent into an inclined portion, a guide section secured to said collecting channel over substantially the full length of said horizontal and inclined portions, said section consisting of a vertical flat plate having its lower edge secured to said channel and a circular bar member having its bottom secured to the upper edge of said plate, said bar member and plate having a radius of curvature corresponding to the curved portion of said channel, and curved hollow elongated split tubular members slidably disposed over said member so the split portion of the hollow members straddles said vertical plate with its split edges spaced from opposite side of said plate, said hollow tubular members having a diameter substantially larger than said bar member to provide a substantial space between the inner surface of said hollow members and the outer circumference of said bar member around the bottom and opposite side portions thereof to allow free play therebetween to enable said tubular members to slide over the curved portion of the guide bar member adjacent the curved portion of said channel, and
