Bladder conveyor systems and method

A transporter for moving an object in a given direction,

• a plurality of elongated, inflatable bladder elements in parallel array, each bladder element having an elongated axis which is transverse to said given direction, there being an X group of said bladder elements connected to a first source of air, a Y group of said bladder elements connected to a second source of air, and a Z group of said bladder elements connected to a third source of air,
• a flexible member joined to each said bladder and forming an object conveying surface, and
• a control unit for pulsing said first, second and third sources of air to thereby sequentially and rhythmically inflate said X, Y and Z groups of bladder elements of epitroichardly raise and lower points on said object conveying surface and move said object in said given direction relative to said object conveying surface.

A method of conveying objects along a path comprising defining said path by an array of elongated inflatable/deflatable bladder elements, providing a flexible member joined to the bladder elements forming an object conveying surface and cyclically inflating and deflating said bladder elements so as to cause an elongated object on said surface to be conveyed in a given selected direction.

A bladder conveyor system comprising an array of elongated bladder elements arranged in groups, each group constituting a given wavelength,

• a flexible member joined to the bladder elements and forming an object conveying surface and means for inflating and deflating said sets of bladder elements so as to cause an elongated object having a length at least as great as said wavelength on said surface to be conveyed in a given direction.
