Flexible conveyor system

A system comprising:

• a torus-shaped flexible membrane having a central axis, the torus-shaped flexible membrane elongated along a direction parallel to the central axis and having an external surface, center channel, and an enclosed cavity;
• a first roller assembly disposed within the enclosed cavity;
• a second roller assembly that applies a force against the external surface and the first roller assembly to cause the torus-shaped flexible membrane to rotate longitudinally around the enclosed cavity to convey objects along the center channel;
• an end unit including:
• a drive shaft configured to receive an input torque,
• a drive wheel coupled to the drive shaft and configured to rotate in response to the input torque, the drive wheel configured to apply a force against the torus-shaped flexible membrane and the first roller assembly, and
• an adjustment device that adjusts a position of the second roller assembly along a direction parallel with the central axis.

A conveyance system comprising:

• a torus-shaped flexible membrane having a central axis, the torus-shaped flexible membrane elongated along a direction parallel to the central axis and having an external surface, center channel, and an enclosed cavity;
• a first roller block positioned within the enclosed cavity at a first end of the torus-shaped flexible membrane;
• a second roller block positioned within the enclosed cavity at a second end of the torus-shaped flexible membrane;
• a first end unit coupled to the torus-shaped flexible membrane at the first end, the first end unit contacting the first roller block to maintain the first roller block at a first position and applying a force against the external surface to cause the center channel to advance along the central axis;
• and
• a second end unit coupled to the torus-shaped flexible membrane at the second end, the second end unit contacting the second roller block to maintain the second roller block at a second position and maintaining a distance between the first position and the second position.
