Actuation system configured for moving a payload
View Patent ↗An actuation system includes a bridge crane, a trolley, and an end effector and is configured for moving a payload. A first actuator is operatively connected to the bridge crane. The bridge crane is configured for moving along an X axis in response to the first actuator being actuated. The trolley extends from the bridge crane. A second actuator is operatively connected to the trolley. The trolley is configured for moving along a Y axis in response to the second actuator being actuated. The end effector extends from the trolley and is configured for supporting a payload. A third actuator is operatively connected to the end effector. The end effector is configured for rotating about the Z axis in response to the third actuator being actuated to rotate the end effector. Each actuator is disposed in spaced relationship to the bridge crane, the trolley, and the end effector.
1. An actuation system configured for moving a payload, the actuation system comprising:
a bridge crane;
a first actuator operatively connected to the bridge crane, the first actuator disposed in spaced relationship to the bridge crane and configured for being actuated;
a first belt operatively connecting the bridge crane and the first actuator such that the first belt moves the bridge crane along an X axis in response to actuation of the first actuator;
a first plurality of pulleys configured to rotate and move the first belt such that the bridge crane moves along the X axis;
a trolley extending from the bridge crane;
a second actuator operatively connected to the trolley, the second actuator disposed in spaced relationship to the trolley and configured for being actuated;
a second belt operatively connecting the trolley and the second actuator such that the second belt moves the trolley along a Y axis in response to actuation of the second actuator;
a second plurality of pulleys configured to rotate and move the second belt such that the trolley moves along the Y axis;
an end effector extending from the trolley and configured for supporting a payload;
a third actuator operatively connected to the end effector, the third actuator disposed in spaced relationship to the end effector and configured for being actuated;
a third belt operatively connecting the end effector and the third actuator;
a third plurality of pulleys configured to rotate and move the third belt;
wherein a pair of the third pulleys are operatively disposed on the trolley; and
a transmission operatively disposed on the trolley between a Z axis of the end effector and the pair of the third plurality of pulleys such that movement of the third belt transmits motion from the pair of the third plurality of pulleys to the transmission to cause the end effector to rotate about the Z axis.
2. An actuation system, as set forth in claim 1 , wherein the first belt is anchored to the bridge crane at a pair of fixed points.
3. An actuation system, as set forth in claim 2 , wherein the first belt is a continuous loop.
4. An actuation system, as set forth in claim 1 , wherein each of the first plurality of pulleys are disposed in spaced relationship to each of the bridge crane, the trolley, and the end effector.
5. An actuation system, as set forth in claim 1 , wherein the second belt is anchored at a pair of fixed points disposed in spaced relationship to the trolley.
6. An actuation system, as set forth in claim 1 wherein the second belt extends between opposing ends and the second belt is anchored at a fixed point, proximate each of the ends.
7. An actuation system, as set forth in claim 6 , wherein two of the second plurality of pulleys are disposed in spaced relationship to each of the bridge crane, the trolley, and the end effector;
wherein four of the second plurality of pulleys are disposed on the bridge crane; and
wherein two of the second plurality of pulleys are disposed on the trolley.
8. An actuation system, as set forth in claim 1 , wherein the third belt is anchored at a pair of fixed points disposed in spaced relationship to the end effector.
9. An actuation system, as set forth in claim 8 , wherein the third belt extends between opposing ends and the third belt is anchored at a fixed point, proximate each of the ends.
10. An actuation system, as set forth in claim 9 , wherein two of the third plurality of pulleys are disposed in spaced relationship to each of the bridge crane, the trolley, and the end effector;
wherein four of the third plurality of pulleys are disposed on the bridge crane; and
wherein six of the third plurality of pulleys are disposed on the trolley.
11. An actuation system, as set forth in claim 1 , wherein each of the actuators are fixed such that each of the actuators do not move with any of the bridge crane, the trolley, and the end effector along the X axis, Y axis, and Z axis, respectively.
