Definitions

  • the present invention relates to belt assemblies, particularly those having wide belts, tracking of such belts and methods of their manufacture.
  • One particular application is a belt assembly for use as a self-propelled support platform solely supported on top of tea bushes.
  • the support platform may carry equipment or machines used in the cultivation and harvesting, but the invention has general application in a wide variety of equipment which uses a wide belt for carrying, supporting or conveying materials.
  • the term 'wide belt' refers to a belt where the width ( transverse dimension) relative to the length (longitudinal dimension, ie the direction in which the belt moves when driven by at least one pulley, roller or the like) causes difficulty with tracking when using existing conventional tracking means.
  • a crowned pulley 2 tracks the belt 3 by deflecting the belt sideways when the belt is tensioned which is caused by the belt 3 wrapped around the pulley 2 aligning itself at 90 degrees to the angle of the crown.
  • This self tracking is well known and very effective in narrow width long belts.
  • wide short belts such as shown in Figure 3, it can be readily seen that a crowned pulley or roller 1 1 cannot cause the belt body 10 to move sideways and the crowned pulley becomes ineffective.
  • a wide belt running with 180 degree contact across the full width of the driven roller then provides a very significant contact area between the belt and roller. Even with the best manufacturing techniques the length of one side of the belt relevant to the other can vary, in some cases by as much as 0.5 mm.
  • the force required to align the belt on the rollers by pushing on the edge of the thin belt is likely to buckle the edge of the belt before overcoming the friction of the belt on the rollers.
  • Another way of tracking that has been previously proposed is to fit a V-type tracking protrusion bonded on the inner side at an outer edge of the belt.
  • the difficulty of tracking as described above overrides the tracking forces provided by V-type tracking protrusion and readily stretches the edge of the belt to a point that the tracking strip is ineffective. External forces acting on the belt can causes the belt to suddenly override the tracking strip and double back to run over the top of the belt turning it inside out on the edges.
  • a belt assembly for carrying, supporting or conveying tools or other articles or materials including a belt which extends around a pair of spaced apart rollers having roller end members, the belt having a tracking strip on at least one side edge, the tracking strip including a tracking portion engageable with a guide portion of a roller end member, wherein the tracking strip is adapted to engage with a drive roller of the pair of rollers and is reinforced so as to be substantially inextensible when the belt is driven by the drive roller.
  • Such an arrangement provides tracking that is unlikely to stretch or misalign and will continue tracking over a long period of time without much adjustment.
  • the belt is adapted to be self-propelled and supported on top of a canopy of tea bushes or other plants for carrying tools or other equipment for use in cultivating or harvesting tea or other plants.
  • the roller end member of the drive roller has flat surfaces in frictional contact with at least one surface of the tracking strip adjacent the tracking portion. This helps to reduce opposing forces on the main body of the belt. Any variation of the belt length on the opposite sides of the belt caused at the time of manufacture or by subsequent inaccurate belt tensioning is accommodated and equalised by minor slippage on the relatively narrow flat drive areas.
  • the other roller of said pair of rollers is preferably an idler roller.
  • the tracking strip is preferably engageable with roller end members of the idler roller via a bearing assembly. Internal bearings of the bearing assembly allow belt forces to equalise so that opposing loads in the belt are reduced.
  • a reinforced tracking strip is provided at each side edge of the belt and engages with the roller end members in such a manner that a central body part of the belt between the reinforced tracking strips is separated from the rollers by a clearance gap. This helps to keep the main body of the belt free from any frictional forces on the parts of the drive and/or idler rollers between the roller end members.
  • the tracking portion of the or each tracking strip includes a tracking protrusion adapted to be received in a complementary guide groove or recess in a respective roller end member.
  • the complementary protrusion and recess are preferably trapezoidal shaped, but may take other forms, for instance they may be V-shaped, U-shaped, or square shaped.
  • the guide grooves or recesses in the roller end members provide guidance for the tracking strip which cannot move out of the guide grooves or recesses because of the substantially inextensible nature of the tracking strip.
  • the belt assembly may also include adjustment means for adjusting the tension of the belt.
  • the adjustment means preferably includes a bearing assembly, a spacer and an adjustment control member.
  • the adjustment means is preferably provided at the idler roller.
  • a belt for use in the belt assembly of the first aspect wherein the belt has a substantially inextensible reinforced tracking strip on at least one side edge, the tracking strip including a tracking portion.
  • both edges of the belt are provided with a reinforced tracking strip.
  • the at least one tracking strip of the belt is preferably reinforced with at least one fibre, wire or cord. More preferably, the tracking strip is reinforced with a plurality of reinforcing fibres, wires or cords, and not just a single fibre, wire or cord in the region of the tracking protrusion.
  • the plurality of reinforcing fibres, wires or cords extend across the flat drive area of the tracking strip immediately adjacent to the tracking protrusion so that the tracking strip is substantially inextensible.
  • the reinforcing fibres, wires and cords provide substantially uniform length and tension across the flat area of the tracking strip to provide substantially uniform drive means.
  • the or each fibre, wire or cord is made from one or more of the following: Kevlar, carbon fibre, steel or other high tensile fibre.
  • the or each fibre or cord may be a multi-strand fibre, wire or cord. The or each reinforcing fibre or cord restrains the belt from stretching even under high loads.
  • the at least one tracking strip preferably extends along the entire side edge of the belt.
  • the belt is made of homogeneous urethane or like material.
  • the at least one tracking strip may be formed integrally with the belt.
  • the at least one tracking strip may be bonded to a side edge of the belt.
  • a drive roller for use in a belt assembly according to the first aspect wherein the roller includes roller end members at each end of a central roller portion, each roller end member having a diameter greater than the central roller portion, flat surfaces for engagement with a tracking strip at a side edge of a belt, and a guide portion for engagement with a tracking portion of the tracking strip.
  • an idler roller for use in the belt assembly of the first aspect, wherein the idler roller includes roller end members at each end of a central roller portion, each roller end member having a diameter greater than the central roller portion, and a guide portion for engagement with a tracking portion of a tracking strip at the side edge of a belt.

Abstract

L'invention concerne un système de bande destiné à porter, à soutenir ou à transporter des outils ou d'autres articles ou matériels, ledit système comprenant une bande (127,128) s'étendant autour de deux rouleaux espacés ayant des éléments d'extrémité de rouleau (165,166), ladite bande étant pourvue d'une lisière de guidage (132) sur au moins un bord latéral, ladite lisière de guidage (132) comprenant une section de guidage (131) pouvant coopérer avec une section de guidage (170) d'un élément d'extrémité de rouleau (165,166). La lisière de guidage (131) est conçue pour coopérer avec un rouleau d'entraînement (163) de la paire de rouleaux et est renforcée de manière à être sensiblement inextensible (127,128) lorsque la bande est entraînée par le rouleau d'entraînement (163). Cet système de bande est particulièrement approprié pour des bandes larges dont la largeur relativement à la longueur peut entraîner des difficultés de guidage lorsque des moyens de guidage classiques sont utilisés.
