Title: Noncontact transporting device
Inventor: SAKAMOTO CHIKA
IPC: B65G49/07
Filed: 1987-01-12
Abstract: PURPOSE:To suspend and hold a workpiece always at a constant distance in air under the non-contact condition by providing a pipe line communicating to a bulging portion through a nozzle to form a jet pipe and unite an air holder with the jet pipe. CONSTITUTION:When a non-contact transfer device B approaches a workpiece C, fluid E is sent into an air holder A and a jet pipe 5 and a cushion chamber 4 has negative pressure to attract the workpiece C. Then, when surface tension between a workpiece mount and the workpiece C is large, a large inertia force will be given to the surface tension when the workpiece C is attracted. When the workpiece C approaches the air holder A, the cushion chamber 4 has positive pressure to produce a force to separate the workpiece C. However, since the inertia force to attract the workpiece C becomes larger than the separating force, the workpiece C tends to contact a bulging portion 3 instantaneously. However, by pressure of fluid jetted from a jet 10 of a jet pipe 5 around the air holder A can be prevented the workpiece C from the contact with the bulging portion 3.
