Tact measurement device for actuator and sensor signal detecting device
First Claim
Patent Images
1. A tact measurement device for an actuator, which measures a tact time taken for a movable member of the actuator to move from one end to another end of a movement range, comprising:
- a first sensor disposed on the actuator and including a first light emitting body to output a first light emission signal;
a second sensor disposed on the actuator and including a second light emitting body to output a second light emission signal;
a detector that comprises a first detector and a second detector, the first detector detecting a first output signal that is defined by the first light emission signal and is output responsive to detecting, by the first sensor, that the movable member is positioned at the one end of the movement range, and outputs a first detection signal, and the second detector detecting a second output signal that is defined by the second light emission signal and is output responsive to detecting, by the second sensor, that the movable member is positioned at the other end of the movement range, and outputs a second detection signal; and
a measurer that measures the tact time taken for the movable member to move from the one end to the other end of the movement range, based on the first detection signal and the second detection signal,wherein the first detector comprises a first output signal detector that detects the first output signal and outputs the first detection signal, and the second detector comprises a second output signal detecting unit that detects the second output signal and outputs the second detection signal.

Abstract
A detecting unit detects a first output signal and a second output signal, which are output by a first sensor and a second sensor disposed on an actuator, and outputs a first detection signal and a second detection signal to a measurement unit. Based on the first detection signal and the second detection signal, the measurement unit measures a tact time taken for a piston to move from one end to another end of a movement range.

8. A sensor signal detecting device comprising:
-
an output signal detector that encloses a signal line connected to a sensor, detects a signal output by the sensor including a light emitting body to output a light emission signal; a detection signal detector that externally outputs the light emission signal that was output by the output signal detector; and a connector configured to detachably mount the output signal detector to the sensor. - View Dependent Claims (9, 10, 11, 12)

13. A tact measurement device for an actuator, which measures a tact time taken for a movable member of the actuator to move from one end to another end of a movement range, the actuator including a first sensor that detects that the movable member is positioned at the one end of the movement range, and outputs a first output signal defined as a first light emission signal, and a second sensor that detects that the movable member is positioned at the other end of the movement range, and outputs a second output signal defined as a second light emission signal, the tact measurement device comprising:
-
a detector that detects the first output signal and outputs a first detection signal, and that further detects the second output signal and outputs a second detection signal; and a measurer that measures the tact time taken for the movable member to move from the one end to the other end of the movement range, based on the first detection signal and the second detection signal. - View Dependent Claims (14, 15, 16, 17, 18, 19)
