Definitions

  • the present invention relates to a motor-rail conveyor system including at least one motor-driven carriage having a drive wheel which rolls on a track of the rail.
  • the object of the present invention is to provide a conveyor system of the type specified at the beginning in which the carriage is able to reduce its own speed automatically on predetermined portions of the track.
  • this object is achieved by the provision of a conveyor system of the type defined above, characterised in that at least one portion of the rail has a second track alongside the first and spaced therefrom in a direction perpendicular to the axis of rotation of the drive wheel and in that the carriage has a second drive wheel fixed coaxially to the first for rolling on the second track, the second wheel having a rolling radius which is less than that of the first wheel and such that the sum of the rolling radius of the second wheel and the distance between the first and second tracks in a direction perpendicular to the axis of rotation of the drive wheels is greater than the rolling radius of the first wheel.
  • the carriage moves at high speed by virtue of the engagement of the larger-diameter wheel with the first track.
  • the smaller-diameter drive wheel encounters and engages the second track and hence the carriage reduces speed automatically without the need to change the speed of rotation of the motor or the transmission ratio of the gear system.
  • the present invention relates to a motor-driven carriage for use in a monorail conveyor system, including a drive wheel intended to roll on a first track of the rail, characterised in that it includes a second drive wheel fixed coaxially to the first and having a rolling radius which is smaller than that of the latter, the second drive wheel being intended to roll on a second track of the rail alongside the first track and spaced therefrom in a direction perpendicular to the axis of rotation of the drive wheels of the carriage.
  • Figure 1 shows part of an overhead monorail conveyor system in which the rail 2 extends along a flat portion 4, a connecting portion 6 and a rising portion 8.
  • a plurality of carriages 10 can run on the monorail and each of these has an electric motor 12, for example a three-phase induction motor, which drives the carriage along the monorail 2.
  • an electric motor 12 for example a three-phase induction motor, which drives the carriage along the monorail 2.
  • the rail 2 has a double-T section and is supported by a plurality of brackets 14.
  • a bar 16 On one side of the rail 2 is a bar 16 which is contacted by a plurality of brushes (not illustrated) carried by the carriage 10, the brushes carrying the electricity supply and any control signals to the electric motor 12.
  • Each carriage 10 includes a basic structure 18 which is generally C-shaped in cross-section.
  • a load-support structure 20 is articulated to the lower arm of the structure 18.
  • the upper part of the structure 18 carries a gearbox 22 (for example of the helical wheel and worm wheel type) on which the electric motor 12 is cantilevered.
  • a pair of drive wheels which are fixed coaxially together are keyed to the output shaft 24 of the gearbox 22 and are indicated 26 and 28 respectively.
  • the drive wheel 26 has a rolling radius R1 about twice that of the rolling radius R2 of the wheel 28.
  • the wheel 26 has a hub 30 keyed to the shaft 24 of the gearbox 22 by a key 32.
  • the hub 30 carries two circumferential bands 34, 36 of polyurethane material, preferably of the type known by the trade name VULKOLLAN, which constitute the wheels 26 and 28.
  • the rail beam 2 has an upper, active portion 38 with a width substantially equal to that of the two adjacent drive wheels 26, 28.
  • the active portion 38 of the beam 2 can be seen to include a first track 40 on which the drive wheel 26 will roll.
  • a profiled section 42 is located on the rail 2 and extends parallel to the first track 40.
  • the upper surface of the profiled section 42 constitutes a second track 44 on which the smaller-diameter wheel 28 is intended to roll.
  • the second track 44 is spaced from the first track 40 by distance H equal to the height of the profiled section 42.
  • the sum of the rolling radius R2 of the wheel 28 and the height h of the profiled section 42 is greater than the rolling radius R1 of the first wheel 26. Consequently, when the wheel 28 rolls on the second track 44, the larger-radius wheel 26 is inactive.
  • the profiled section 42 has an inclined connecting portion 46 at each end (only one of which is visible in the drawing) on which the changeover from one drive wheel to the other occurs.
  • Each carriage 10 also has a series of vertical-axis guide wheels 48 which bear against opposite sides of the rail 2.
  • the lower part of the carriage 10 carries a pair of wheels 50 which are spaced apart in the direction of the rail 2 and intended to bear against and to roll on a surface of the latter opposed to the active portion 38.
  • the carriages 10 move at high speed along the flat portions of the rail 2 since the larger-radius wheel 26 rolls on the first track 40 of the rail 2.
  • the smaller-radius wheel 28 encounters the profiled section 42, the velocity of the carriage 10 falls automatically although the rate of rotation of the electric motor 12 remains almost constant.
  • a relatively small-power motor suffices to drive the carriage and its load up the rising portions.
