Definitions

  • the present invention relates to an overhead travelling conveyor adapted to travel on an I-shaped monorail. More particularly, it is concerned with an overhead travelling conveyor suitable for conveyance which may involve frequent starting and stopping, especially sudden stopping, and which is also suitable for a curved rail.
  • Conventional overhead travelling conveyors have a structure in which right and left wheels of a carrier travel on a rail composed of a pair of channel members fixed to a support member and in which bus bars for supplying power to a running motor are disposed inside the rail.
  • This structure ensures safety even in the use of bare bars, but since the wheel diameter is restricted to a relatively small diameter, it is necessary to increase the number of wheels when the conveyed load is large.
  • a special quenched rail must be used with the result that the rail weight becomes larger.
  • FR-A-2387 149 describes an I-shaped monorail, the upper flange surface of which is conversely curved to support the wheel of the carrier, which has a corresponding peripheral groove to fit over the rail.
  • Guide wheels are positioned to engage the bottom flanges of the rail to provide lateral stability and receive lateral forces on the carrier wheel.
  • the upper and lower flange surfaces form recesses on both sides of the monorail by virtue of their shape.
  • an overhead travelling conveyor including a monorail which comprises
  • a conveyance article holding means is supportd through a spherical bearing attached to the conveyance article holding means suspending portion of the load bar, so even if a lateral load is exerted on the conveyance article holding means and the conveyance article itself during travelling on a curved portion of the rail or during working, such load can be absorbed by the spherical bearing. Consequently, only vertical loads are imposed on the wheels and the guide rollers do not undergo a large lateral load, so that the rail is not subject to a torsional load nor are the load bar connecting pins subject to an excessive load.
  • a notched portion of a size which permits the lower portion of the carrier to be removed sideways of the monorail is formed in part of the lower portion of the monorail of I-shaped section, and a rail piece corresponding to such notched portion is fixed detachably to the notched portion.
  • a carrier 11 comprises a driving carrier 13 and a driven carrier 14 both adapted to travel on a rail 12 of I-shaped section and interconnected through a load bar 15. From the load bar 15 is suspended conveyance article holding means 16 such as an electrically operated chain block, hoist, or the like.
  • the driving carrier 13 has a generally E-shaped frame 20 on the upper part of which is mounted a bearing portion 21 which supports an axle 23 of a cylindrical wheel 22 adapted to travel on the rail 12, the wheel 22 being formed of rubber or synthetic resin such as nylon.
  • the wheel 22 being formed of rubber or synthetic resin such as nylon.
  • an upper arm 24 and an intermediate arm 25 of the frame 20 respectively, on which are mounted vertical-axle guide rollers 26 and 27, respectively, adjacent to both sides of the rail 12, the guide rollers 26 and 27 being formed of rubber or synthetic resin.
  • the guide rollers 27 prevent lateral swinging of the driving carrier 13. Therefore, only a single pair of right and left guide rollers 27 may be provided below the wheel 22.
  • Both ends of a vertical pin 29 are inserted and fixed into holes respectively formed in the intermediate arm 25 and a lower arm of the frame 20 on a perpendicular which passes the center of the wheel 22, and one end of the load bar 15 is fitted on an intermediate portion of the pin 29 through a bushing.
  • a running reduction motor 30 is attached to the back of the lower portion of the frame 20.
  • the wheel axle 23 and the motor shaft are connected for power transmission through toothed belt wheels 31 and 32 and a toothed belt 33.
  • the toothed belt 33 is kept tensioned by a roller 34 mounted on the frame 20.
  • the driven carrier 14, as shown in Figs. 4 and 5, is similar to the driving carrier 13 and has an E-shaped frame 35, a cylindrical wheel 36, guide rollers 37 and 38 and a pin 39.
  • the other end of the load bar 15 is fitted and supported on the pin 39 similarly to the case of the pin 29.
  • the driven carrier is further provided with collector means for receiving power for the running motor 30 and the electrically operated chain block from trolley lines 40 and for transmitting and receiving control signals.
  • a support structure for the trolley lines 40 in which many grooves 43 are formed in the outside of support means 41 and a notched concave 44 is formed between adjacent grooves 43 to form resilient deformable legs 45 at opposite sides of each groove 43, and a latch portion 46 projecting into the groove 43 is formed on the outer end of each leg 45.
  • Each of the bus bars 40 comprises an extruded member having a generally square external form and a hollow portion 47. It is provided with a longitudinal opening 48 at one side of the hollow portion and with retaining portions 49 projecting on both sides of the opening 48. A side wall opposed to the opening 48 is slightly inwardly concaved to form a slightly concaved outer surface of the side wall which outer surface serves as a sliding contact surface 50, and projecting portions 51 are formed on both sides of the sliding contact surface 50.
  • Each of the bus bars 40 has such a sectional shape.
  • the bus bars 40 are each fitted into an insulation sheath 52 having a S-shaped section and held in place by projections 53 formed at both edges of the sheath 52.
  • the assembly thus fabricated is press-fitted into the groove 43 and held in place by the latch portions 46.
  • a connector fitting 54 which spans both trolley lines is inserted into the hollow portion 47 and a screw 55 is threadedly inserted through the opening 48 and is fastened so that the leading end of the screw is brought into pressure contact with the inner wall of the hollow portion 47, whereby both side portions of the connector 54 are forcedly contacted with the inner surfaces of the retaining portions 49.
  • the upper three bus bars are power supply lines for the motor and the lower two are control signal lines for insulating a specific section from the other sections to effect starting or stopping of the carrier.
  • the bus bars 40 are covered with the insulation sheath 52 as previously noted, and it is only a slight projection of the screw 55 that projects at the junction of trolley lines. Therefore, the bus bars 40 can be laid easily and compactly with a high accuracy in proximity to the web 18.
  • tip end portions of upper and lower rail fixing members 42 of the bus bars supporting means 41 are inserted into concave portions formed between a side face of the web 18 and projections 17, then bolts 42a are threadedly fitted into threaded portions 42' formed in the rail fixing members 42 and tightened to let the leading ends of the bolts 42a come into pressure contact with the side face of the web 18 and the rail fixing members 42 into pressure contact with side faces of the projections 17, whereby the bus bars supporting means 41 is fixed to the rail 12.
  • the bus bar supporting means 41 as shown in Fig. 7, is first disposed sideways on a side face of the rail web 18 and then turned to a predetermined position.
  • Collector shoes 57 which are in sliding contact with the bus bar 40 are attached to an insulation plate 56 which is fixed by screws to the frame 35 of the driven carrier 14, as shown in Fig. 5. Since the driven carrier 14 scarcely undergoes a lateral vibration as previously noted, there may be used small-sized collector shoes 56 having only a limited range of movement, whereby a good current collecting effect can be attained.
  • the I-shaped rail 12 is formed of aluminum or other material by extrusion.
  • Recessed portions 18a for a rail connecting plate are formed along the longitudinal direction in both side faces of a web 18, and pressure-mounting projections 17 for the rail hanger means and for the power supplying and signalling bus bars supporting means are formed along the longitudinal direction of the side faces of the web 18 on the opposed faces of upper and lower flanges 12c which form a running surface 12a for the wheels of the monorail travelling conveyor and guide surfaces 12b for the guide rollers of the conveyor.
  • Figs. 9 and 10 are a side view and a front sectional view, respectively, there is shown the rail 12 as suspended and fixed by rail hanger means 60. More specifically, a rail fixing member 61 provided at the tip end portion of the rail hanger means 60 which is fixed to the ceiling is brought into abutment with the outer surfaces of one projections 17 of the rail flanges 12c, then bolts 63 are each inserted through a bolt hole 62 of the rail fixing member 61 into a threaded portion 65 of a patch plate 64 which is partially fitted in the concave portions formed between the side face of the web 18 and the projections 17, and then tightened, whereby both side faces of the projections 17 of the rail flanges 12c are gripped by the rail fixing member 61 of the rail hanger means 60 and the patch plate 64 to thereby fix the rail 12 to the rail hanger means 60.
  • the patch plate 64 is first sideways disposed on a side face of the web 18 and then turned to a predetermined position, as shown in Fig. 11.
  • the numeral 76 denotes a mounting space for the connector fitting for connection of power supplying and signalling bus bars formed in each rail section. Since the drilling reference lines 18b are provided on the side faces of the web 18 along the longitudinal direction, it is very easy to machine the rail connecting bolt holes 74, etc.
  • Both ends of the load bar 15 are supported by the pins 29 and 39 which are supported at the respective both ends by the frames 20 and 35, respectively, as previously noted.
  • This mounting provides a highly strong resistance against the inertia force of the conveyance article induced at the time of sudden stopping and also against a bending moment applied to the pins 29 and 39 due to the conveyance load at a sloped portion of the rail.
  • the hanger In the case of suspending a conveyance article by a hanger attached to the load bar 15, the hanger is supported by the load bar 15 through a ball bearing.
  • the pins 29 and 39 act as both end-supported beams, so can maintain a sufficient strength even against a sharp curve, and the surface pressure of the guide rollers 27 and 38 is reduced remarkably and their life much prolonged.
  • FIG. 14 is a sectional view of a principal portion for supporting the conveyance article holding means by a spherical bearing, in which the conveyance article holding means 16 such as a chain block or hoist is supported in a suspended state through a suspending connection pin 81 by a spherical bearing 80 which is attached to the conveyance article holding means suspending portion of the load bar 15.
  • a notched portion 90 of a size which permits the lower portion of the carrier to move out therefrom sideways of the rail 12.
  • a rail piece 91 corresponding to the notched portion 90 is fixed with bolts 93 to a mounting plate 92 which is fixed to one side of the web 18 in the position of the notched portion 90.
  • the driving and driven carriers 13 and 14 when the driving and driven carriers 13 and 14 are to be detached from the rail 12, first the rail piece 91 is removed from the rail 12, then those driving and driven carriers after removal therefrom of the conveyance article holding means 16 such as an electrically operated chain block or hoist and the load bar 15 are each successively brought into the position of the notched portion 90 of the rail 12, and the carrier now located in that position is moved sideways, whereby the driving and driven carriers 13 and 14 can each be detached from the rail 12.
  • the carriers 13 and 14 can be loaded onto the rail 12 in accordance with operations reverse to the operations just described.
