Appl. No.:

10/040423

Inventors:

James F. Harrington - Lexington OH
Joseph A. Leaf - Mansfield OH

Assignee:

Dallas Design and Technology, Inc. - Lexington OH

International Classification:

B23Q 3155

US Classification:

Abstract:

A system for changing a tool head ( ) carried by a robot ( ) includes a locking mechanism ( ) having a keyhole-shaped slot ( ) therein, and a lock key assembly ( ) having a key ( ). Depression of a button ( ) rotates a cam arm ( ) to extend the key ( ) outwardly where it can be received in the larger opening ( ) of the slot ( ). Depression of the button ( ) of the locking mechanism ( ) moves the slot ( ) such that the neck ( ) of the key ( ) is received in the smaller opening ( ) of the slot ( ). Release of the buttons ( ) then allows a spring ( ) to retract the key ( ) until its head ( ) is received in a recess ( ) of the locking mechanism ( ) to attach the tool head ( ) to the robot ( ). The parts are detached by again depressing the button ( ) which extends the key ( ) to remove its head ( ) from the recess ( ) and then depressing a button ( ) to move the slot ( ) so that the key ( ) is again in the larger opening ( ) from where it may be removed. The system may be operated manually or operated automatically at a docking station ( ).

Abstract:

A device (10) for inflating an object such as a ball (B) includes spaced arms (13, 14) carried by a bar (12). The arms (13, 14) are spaced a predetermined distance approximating the properly inflated diameter of the ball (B). An inflation needle (24) is positioned generally midway between the arms (13, 14) and is adapted to provide air under pressure, received through flexible tubing (26), to the ball (B). A clamp bar (28) is pivotally attached to one of the arms (13, 14) and has an aperture (33) therethrough to receive the tubing (26). When the ball (B) is being inflated, it will engage and pivot the clamp bar (28) until it pinches the tubing (26) to terminate the air flow to the needle (24).
