Definitions

  • the present invention relates to a conveyor compris ⁇ ing a stationary track the extent of which comprises sections at different levels, movable elements which are guided by the track for movement along this, a supporting member on at least some of the movable ele ⁇ ments, and a device for maintaining the supporting mem ⁇ ber in a predetermined angular position regardless of the position of the movable element during its movement along the track, wherein the supporting member is mounted for rotation about a substantially horizontal axis in the movable element, and wherein the device for main ⁇ taining the supporting member in the predetermined posi- tion comprises an actuating mechanism connected with the supporting member, and a guide track arranged wholly or partially along the stationary track to interact with the elements in the actuating mechanism.

  • a conveyor of the type mentioned above is known previously from DE-OS 2429282 and more particularly re- lates to. the conveyance of batches of newspapers between different processing stations.
  • This known conveyor has several disadvantages.
  • the supporting member which has to be kept in a predetermined angular position during transportation along the stationary track is not reliab- ly positively-controlled in order to maintain the prede- ter ined (in this case vertical) position along the track.
  • the object of the present invention is to provide a conveyor of. the type referred to above, which can easily be run along an arbitrary path extending between different levels and having more or less complicated runs at each level , and in which the movable elements with the supporting members mounted thereon are reliab ⁇ ly and infinitely-variably controlled so as to positive ⁇ ly maintain the predetermined position of the supporting member in each position in the stationary track by means which require minimum maintenance and which eliminate the risk of inadvertent manipulation and the risk of the movable elements binding during their movement or jamming at any point along the movement path.

  • the plate 35 is maintained constantly in the horizontal position regardless of the position adopted by the trolley, because the location of the plate is fixed as a result of the engagement between the teeth of the gear wheel 37 and the rack 40 in each position of the trolley along the track 10.
  • tooth guidance is required only in the curves made by the rails in the vertical direction, whilst guidance can be provided with other and simpler means in the absolutely vertical and the absolutely horizontal portions of the rail.
  • end wall 28 there are pins 41 with rotably-mounted cam rollers 42.
  • stationary angle profiles 43 are arranged, with one flange fastened to the walls 14, whilst the other flange projects from the angle profile, so that these flanges form a guide groove on the front of the box profile.
  • the flanges are arranged at an angle in respect of each other over shorter sections 43'.
  • the cam rollers 42 run in between the angle profiles the distance between the projecting flanges being so adjusted that the cam rollers .42, rolling against the flanges, keep the rotable device 27 in the predetermined angle of rotation.
  • the guidance function is thus removed completely from the gear wheel/rack and accordingly the rack can in these sections be dispensed with completely, or perhaps also they can be maintained but made considerably narrower if it is wished to main ⁇ tain continuous tooth engagement over the entire length of the track.

  • the trolley is shown built up from two side plates 118, which do not prevent the locking mechanism being employed in conjunction with the trolley described
  • FIG 7 illustrates the components forming part of the locking mechanism,' such as a detent hook 141, and a circular disc 142 with recesses 143 provided therein.
  • the disc 142 is rotary together with the shaft 134.
  • the detent hook 141 is loaded by means of the spring 146, so that the detent hook engages reliably the re ⁇ cess 143 when the trolley 116 adopts a horizontal or vertical position, or in transport paths where the in- clination is for example 45°, a position corresponding to this inclination.
  • the function of the locking mechanism is as follows Just before the trolley 116 reaches a vertical rail radius, the gear wheel engages with the rack 140 (FIG 8). After reliable engagement has occurred and be ⁇ fore the rail radius starts a pulley 144 which is con ⁇ nected with the detent hook comes into contact with an entrance chamfer 145 of the rack whereby during the continued movement the detent hook is lifted to dis- engage the recess 143 so as to permit rotation of the shaft 134 which is connected with the disc, relative to the trolley 116.
  • FIGS 9 - 11 differs from the embodiments previously described mainly in that the rack 40 and the gear wheel 37 with its bearings are replaced by a guide track 243 with teeth designed to interact directly with an external adjustment device 242, 252 forming part of an actuating mechanism also comprising a reduction gear between the adjustment de ⁇ vice and the supporting member 34.
  • the track has been made open and consists of two tubes 213 which at a suitable spacing are held together by spacers 211.
  • a track of this type can of course also be employed in the embodiment with rack initially described.
  • the trolley 216 consists of two plates 218 which are held together partly by a central boss 244 and partly by a distance boss 245 and by two end tubes 246.
  • U-shaped straps 246 are rotably mounted at each end of the latter. Each strap functions as a bearing for a runner wheel 222 having a shape adapted to suit the track formed by the two tubes 213.
  • the hub 244 of the trolley 216 forms the mounting for the supporting member or shaft 34, on which a plate can for example be provided.
  • An internally-toothed wheel rim 254 is fastened to the shaft 34, engaging a smaller gear wheel 248, the shaft 249 of which is mounted in the distance boss 245.
  • a larger gear wheel 250 which engages with an internal gear wheel 251 mounted on the hub 244 is fastened to the same shaft.
  • a roller holder 252 with four symmetrically arranged pins comprising mountings for four rollers 242 is fastened to the inner gear wheel 251. These rollers together with the roller holder 252 form a 4-toothed "gear wheel" which during the movement of the trolley along the track interact with a guide rail 243. As shown in FIG 10 this rail is straight along
  • the guide rail or guide track 243 is designed as a gear rim.
  • the gear wheel 242 as a result of its engagement with the gear rim is forced to rotate.
  • This rotational movement results in rotation of the gear wheel 251, the pair of gears 250, 248 and of the gear wheel 254 with the shaft 34 fastened therein.
  • pitch of the gear rim 243 and of the reduction ratio between the gear wheels 251/250 and 248/254, respectively it is possible to obtain rotation of the shaft 34 which exactly compensates for the rotation .imparted to the trolley during its passage along the curved track.
  • the trolleys 216 are held together so as to form an endless chain by means of links 217 and possibly intermediate trolleys 253.
  • the "gear wheel” 242 can be designed in the same way as a conventional gear wheel with several teeth. By selecting only four teeth however, two of these can advantageously be employed also for guidance along the straight portions of the track.
  • Driving of the endless chain can be brought about by automatically engaging for drive purposes the trolleys with an endless pulling device which extends along the straight portion of the conveyor path or, in the case of the embodiment of the conveyor initially described, by virtue of the fact that the gear wheels 37 are pro- vided with drive motors, at least on some trolleys.
