Definitions

  • the present invention relates to conveyors, and more particularly, to live conveyor systems for transporting loads over a series of driven conveying belts.
  • Live conveyor systems which transport loads without gravity assistance are generally well known in the art.
  • One type of conventional live conveyor system is disclosed in U.S. Patent No. 4,293,065, which is assigned to the assignee of the present invention.
  • the conveyor system disclosed in this patent includes a plurality of load-carrying rollers supported for rotation and arranged above an endless driving means.
  • the endless driving means includes an upper frictional contact pass for engaging the load-carrying rollers wherein movement of the endless driving means results in rotation of the load-carrying rollers such that loads supported on the rollers are carried downstream.
  • a plurality of conveying zones extend longitudinally along the length of the conveyor wherein the endless driving means is vertically movable into and out of engagement with the load-carrying rollers in each individual zone.
  • the load-carrying rollers in each zone may be independently driven in rotation whereby loads may be accumulated within the various zones extending along the length of the conveyor.
  • Sheet walk occurs when a bottom sheet is displaced with respect to the remaining sheets in a stack.
  • Sheet walk may be contributed to the fact that the leading edge of the bottom sheet of a stack engages a vertical surface of each load- carrying roller as the stack is transported downstream.
  • Each load-carrying roller essentially pushes against the bottom sheet in a direction opposite to the movement of the stack such that the bottom sheet begins to lag behind the remaining sheets in the stack.
  • the entire stability of the stack is compromised, often resulting in serious skewing, misalignment, or collapsing of the stack at it reaches a downstream end of the conveyor. Additionally, contact between leading edges of the sheets and successive rollers may damage the sheets, resulting in their rejection as defective products.
  • the conveying band comprises a single loop of flat-link chain which passes around drive and tensioning rollers positioned at opposing ends of the system.
  • the chain conventionally extends longitudinally along a center axis of the conveyor system and separates a pair of load support surfaces.
  • Various portions of the conveying chain are vertically moveable to a position above the adjacent support surfaces for selectively engaging and transporting loads in contact therewith.
  • conveying chains have outwardly extending protuberances which often mark or damage the'bottom sheet in a stack. In many instances, the damage may propagate up through the stack thereby damaging additional sheets.
  • typical conveying chains are made of metal such that their operation is noisy and requires extensive regular maintenance, including the use of expensive lubricants.
  • the above described endless chain conveyor system has limited flexibility in selectively controlling the transport speeds of different loads since the chain travels at a uniform speed along its length. Different loads along the length of the conveyor must either be at rest or move at the same speed as other loads on the chain.
  • a conveyor system having independently controllable conveyor zones is disclosed in U.S. Patent No. 3,187,878. Each conveyor zone includes a plurality of laterally spaced belts wrapped around a common pair of rolls. The belts in each adjacent conveyor zone are overlapping such that the upper runs of the belts in one zone are overlapping with respect to the upper runs of the belts in an adjacent zone.
  • Prior art conveyor systems typically provide little, if any, flexibility in allowing expansion of the system in either lateral width or longitudinal length. Essentially, each conveyor system has to be installed with a defined width and length which may not be readily modified. The overall operative dimensions of the conveyor system cannot be altered without effectively requiring the construction of an entirely new conveyor system.
  • the present invention provides a conveyor system for transporting loads and, more particularly, for transporting stacks of sheet product with improved stability.
  • the conveyor system also facilitates efficient maintenance and flexibility in modifying its length or width.
  • the conveyor system of the present invention includes a plurality of adjacent conveying sections extending longitudinally, or in the machine direction, from an upstream end to a downstream end.
  • Each conveying section includes a plurality of laterally, or cross-machine, spaced modular conveying units.
  • the conveying units of each section are supported on a plurality of laterally extending crossties which, in turn, are supported on a floor surface.
  • Each conveying unit includes a continuous belt wrapped around first and second rotatably mounted end supports which define first and second ends of a belt path of travel.
  • Each belt includes upper and lower runs separated by the end supports.
  • the first and second end supports of each conveying unit are rotatably supported within a belt support frame which, in turn, is supported for selective lateral movement along the plurality of crossties.
  • a propelling member is supported intermediate the first and second end supports and engages the lower run for driving the endless belt in motion.
  • the propelling member of each conveying unit is operably connected to a laterally extending drive shaft.
  • the drive shaft is driven in rotation by an electric gear motor preferably positioned laterally proximate the longitudinal axis of the conveying section.
  • each conveying unit is laterally offset from the belt paths of the conveying units of each adjacent conveying section. Additionally, the belt path of each conveying unit longitudinally overlaps with the belt paths of the conveying units of each adjacent conveying section. More particularly, each end support preferably includes upstream and downstream end surfaces and a laterally extending center axis, wherein the center axes of the second end supports of each conveying section are positioned longitudinally downstream from the upstream end surfaces of the first end supports of an adjacent downstream conveying section. Therefore, it is an object of the present invention to provide a conveyor system providing for improved stability of sheet product conveyed thereon by eliminating load-carrying rollers.
