Abstract
A method and apparatus for delivering and retrieving workpieces to and from a machine table. This invention also relates to an apparatus for receiving at the machine table workpieces which are delivered to and retrieved by the delivery system. Carriers move along a conveyor without a loading arm rotating with respect to a supply table and also without the supply table rotating with respect to the loading arm. The receiver has pivot arms that act in a scissor-like manner to open and close an opening that lockingly engages a connector connected to a pallet.
Claims18
An apparatus for receiving at a machine table workpieces delivered to and retrieved by a delivery system, the apparatus comprising:
- a receiver having a receiver body removably mounted with respect to the machine table, the receiver body forming a cavity and a bore in communication with the cavity, the receiver body having an opening connected to the cavity and bore, at least one pivot arm pivotally mounted with respect to the receiver and movable to expose the bore, a spreader movably mounted with respect to the receiver body, the spreader contacting the at least one pivot arm, a bias element mounted with respect to the receiver body and normally forcing the at least one pivot arm into a locked position to interfere with and detachably lock within the bore a male connector of the delivery system;
- a plunger movably mounted within the opening and connected to the spreader, and moving the spreader against a force of the bias element moving the at least one pivot arm open;
- and
- an actuator of the delivery system movable into and through the opening with respect to the plunger, wherein the actuator is connected to a loading arm of the delivery system and the actuator moves the plunger which moves the spreader.
A method for receiving at a machine table workpieces delivered to and retrieved by a delivery system, the method including the steps of:
- removably mounting a receiver with respect to the machine table;
- moving an actuator connected to a loading arm of the delivery system to an opening of the receiver and within the opening, the opening connected to a bore of the receiver, and engaging the actuator with a spreader and the actuator moving the spreader with respect to at least one pivot arm pivotally mounted with respect to the receiver and exposing the bore of the receiver;
- moving the actuator and a male connector and engaging the male connector within the bore;
- moving the at least one pivot arm into a locked position to interfere with and detachably lock the male connector within the bore;
- and
- moving the actuator to the opening of the receiver and within the opening to move the spreader and move the at least one pivot arm to release the male connector from within the bore.
