Definitions

  • the invention relates to a chain-conveyor with two tubular profile rails, one being placed vabove the other and each having a slit extending in the longitudinal direction.
  • the object of the invention is to device a chain-conveyor'of the type indicated in which the said drawbacks are remedied in such a manner that it is made possible to obtain a series of improvements that will be described in the following specification.
  • the characterizing features of the chain-conveyor according to the invention are that the lower prole rail is positioned with its slit facing downwards, whereas the upper one is positioned with its slit facing upwards, and that the two profile rails are connected with each other to form a strong section.
  • the lower prole rail is closed'at the top, while the upper profile rail is closed at the bottom.
  • the two profile rails may easily 1be welded together to form a-iirm unit, and this unit need only be suspended at one side so that a simple mounting of the rails is obtained. It is easy and inexpensive to bend the almost closed tubes so as to form Ycurved portions with precise profiles.
  • the upper profile rail forming a closed circuit, according to the invention, there may be placed a circulat,- ing driving chain.
  • the lower profile rail which may have interruptions for sidetracks, serves as a ⁇ track for the carrying trolleys,
  • the driving chain may have dragging members for dragging the trolleys. Because there is no profile rail. This is itself entails a complication. On ⁇ the ,other hand, far better possibilities are obtained for the Vconnection of side-tracks, so that the trolleys can be pushed into such sidetracks, e.g., onto storage lines, As
  • the dragging members may thus, according to ⁇ the invention, be disconnectably positioned in relation to the trolleys.
  • jdraggingmembers may, according to the invention, consist of downwards projecting arms that are pivotable on ⁇ an axis in the chains longitudinal direction.
  • the drag- 3,345,954 Patented Oct. 10, 1967 ICC ging members may, according to the invention, have sensing means for sensing controlling members which are placed beside or near the profile rails and which can cause disconnection ofthe dragging members from the trolleys.
  • sensing means for sensing controlling members which are placed beside or near the profile rails and which can cause disconnection ofthe dragging members from the trolleys.
  • the driving chain has horizontal axles with rollers mounted thereon that can bear upon either the top or the lbottom of the profile rail.
  • Each dragging member according to the invention may be supported by two successive rollers.
  • the successive rollers may be connected with each other by means of chain links that do not permit lbending on a horizontal axis.
  • the dragging member may be hinged upon a supporting construction, that is supported upon the two rollers, and that is constructed so as to chanen the intermediate portion of the chain. It is not necessary to construct the intermediate portion of the chain with a strength great enough to be able to stand the entire torque produced by the dragging member, but the chain may be constructed with a strength that otherwise would be suitable for the chain in connection with its pulling function. Since the chain has chain links with vertical axes between the two rollers, the said supporting construction for the dragging member must have corresponding links with vertical axes coincident with vertical axes of the chain for passage through horizontal bends in the profile rail track.
  • the trolleys may be constructed entirely or partly as chain portions, at each end having an arm that is pivotable on a vertical axis and at 4the end of this arm having a buffer member constructed with a width equal to the interior width of t-he prole rail,
  • FIG. 1 shows a vertical longitudinal section through a 'portion of the chain-conveyor
  • FIG. 2 is a cross-section in same
  • FIG. 3 is a longitudinal section through a side-track with two trolleys
  • FIG. 4 is a view similar to the view in FIG. 2 of a second embodiment.
  • the numeral 1 designates an upper prove rail that is formed like a tube with rectangular cross section and with a slit 2 at the top.
  • This profile rail 1 is, by means of an intermediary member 3 and welding, connected to a lower prole rail 4 that is shaped like a tube with the same cross-section as the tube 1, but with a slit 5 placed at the Ibottom.
  • the tubes 1 and 4 thus form a firm unit, and the latter is suspended by means of supporting members (not shown) fastened to the right side of tubular rails 1 and 4 as shown in FIG. 2.
  • a circulating driving chain driven by means of a driving mechanism (not show) at a certain point of the circuit.
  • the chain has rollers 6, with horizontal axes and with a diameter that is slightly less than the height of the tube 1, and horizontal rollers 7 with vertical axes and with a diameter that is slightly less than the width of the tube 1.
  • the rollers I6 are double rollers on a horizontal axle, on which there is placed an angle piece with a horizontal arm 8 and a vertical arm 9, and on which there furthermore is placed a universal joint 10.
  • the horizontal axle provides a chain joint axis.
  • the rollers 7 are placed between two link plates 12 and 13 by means of a vertical axle 11.
  • the two horizontal arms 8 are directed towards each other, and are connected with the ends of the link plates 12 and 13 by means of Vertical link pins 14 and 15.
  • the two universal joints 10 are directed away from each other and are connected with the link plates 12 and 13 by means of vertical link pins 16 and 17.
  • the link pin 14, 15, 16 and 17 thus form chain joints with vertical axes.
  • Each of the arms 9 is fastened at the top to a universal joint 18 and 19, each of which having a vertical link pin 20 and 21 -for a hinge axle 22.
  • the link pins 20 and 21 are placed exactly above the link pins 14 and 15.
  • axles for sensing rollers 26 and 27 In apertures in the plate 24 there are -placed axles for sensing rollers 26 and 27 that can cooperate with not shown guide members shaped like cams or rails placed on the side in question of the profile rails 1 and 4 so that the dragging arm thereby may be swung away from the profile rails.
  • each of these trolleys comprises a trolley link 28 that at each end has supporting rollers 29 and at each end has a universal joint 30 for connection to an arm 31 or 32, respectively, that is formed with a fork 33 or 34, respectively, at the end.
  • the rollers 35 have a diameter nearly equal to the interior height of the profile rail 4, and the rollers 36 have a diameter nearly equal to the interior width of the profile rail 4.
  • the trolley portions form a chain portion, advantageously having a pitch corresponding to -pitches of the chain in the upper profile rail.
  • the lower rail corresponds precisely to the lower rail in the iirst embodiment, but the upper rail consists of a tube 50l with circular cross-section with a ange 51 placed opposite the slit 52.
  • the rail 50 is considerably smaller than the lower rail.
  • the driving chain in this embodiment is similar to the driving chain in the rst embodiment, but is adapted in size and shape to the circular cross-section of t'he rail, e.g., the periphery of the rollers 56, corresponding to the rollers 6, is oblique as indicated at 57.
  • the trolleys 58 correspond precisely to ⁇ the trolleys placed in the lower rail of the embodiment shown in FIGS. 1-3.
