<p>A pneumatic action system for parts comprises a conveying track (11a) on which parts are conveyed, a pneumatic route (AR) including a distal end side opening portion (11c) facing said conveying track, an operating space (OS) into which a proximal end side opening portion (14b) of said pneumatic route is opened, said operating space being surrounded by partition walls, at least one portion of which is constructed by a flexible diaphragm (17), a driving means (18) for driving and deforming said diaphragm so as to increase or decrease a volume of said operating space, and a control means (SC, DC) for controlling said driving means so as to repeat an irregular or regular operating cycle in which said diaphragm is deformed in a first direction so that a volume of said operating space is increased or decreased to generate pneumatic pressure and said diaphragm is thereafter deformed in a second direction opposite to the first direction to recover the volume of said operating space, wherein said control means (SC, DC) controls said driving means such that a second displacement period (DP2) from a start of displacement in the second direction of said diaphragm to a start of displacement in the first direction thereof for generating the following pneumatic pressure is made longer than a first displacement period (DPI) from the start of displacement in the first direction of said diaphragm to the start of displacement in the second direction of said diaphragm.</p> |
