摘要:
A controller for a work implement (10, 30) of a construction machine (1, 3) comprising: a manipulating signal input unit (21) including a target value computing section (25) for generating an operation target value (V1) for the work implement (10, 30) based on a manipulating signal (F, Fa) inputted from a manipulating unit (2) for manipulating the work implement (10, 30), a target value correcting unit (22, 37) for correcting the generated operation target value (V1), and an instruction signal output unit (23) for outputting an instruction signal to an actuator (19, 34) for driving the work implement (10, 30) according to the corrected target value (V2); wherein the target value correcting unit (22, 37) comprises a vibration suppressing unit (29) for correcting the operation target value (V1) to another target value to suppress vibrations of the construction machine (1, 3) according to the vibration characteristics, which vary according to a posture of and/or a load to the work implement (10, 30).

摘要:
A control device for a work carrying system characterized in that a first point where the moving action of a work transitions from a moving action from an origin process chamber to a transfer chamber to a moving action inside the transfer chamber and a second point where the moving action of the work transitions from the moving action inside the transfer chamber to a moving action from the transfer chamber to a destination process chamber are set on a moving path of the work, and that speed patterns on the moving path are set based on a transfer distance of the work and time required to open and close gate means of the origin and destination process chambers such that the opening of a gate valve at the destination is completed when the work reaches the second point on the moving path and that a transfer time from the first point to the second point becomes the shortest time which is longer than the opening and closing time of the gate valve, the speed of a work carrying robot being controlled in accordance with the set speed patterns, whereby any chance of the robot being temporarily stopped is minimized so as to effect high-speed carrying of a work such as a wafer requiring a shortest possible carrying time.
