Abstract
Abstract A machine tool center includes a machine tool, a tool storage magazine storing a multiplicity of tools, a workpiece storage area, a robot assembly, and a control system for controlling the operation of the robot assembly and of the machine tool. The robot assembly has a telescoping arm supported on a body which is movable relative to its base, and at the outer end of the arm is a gripper member which is pivotally supported intermediate its length and includes gripping elements at each of its ends. A workpiece engageable member has grippable elements thereon which can be received in the gripper member, and the gripping member will also grip tool members for movement between the tool magazine and the machine tool. Various drive units are provided for effecting movement of the various elements of the robot body. The gripper member thus serves the dual function of engaging the tooling and of engaging the workpiece engaging member to effect movement of the workpieces from the machine tool to the storage area.

Dependent Claim
293 words
In a machine tool center having (1) a machine tool for performing work upon a workpiece and having a work support station and at least one tool mounting station, (2) a tool storage magazine spaced from said machine tool and having a multiplicity of tool storage positions having stored therein tool members with grippable elements thereon, and (3) a workpiece storage area spaced from said machine tool, the combination therewith of: (A) a robot assembly for inserting and removing tools from said magazine and said tool mounting station and transporting them therebetween, and for moving workpieces between said work support station and said workpiece storage area; and (B) a control system for controlling the operation of said robot and of said machine tool, said robot assembly having: (i) a base; (ii) a body movable on said base at least about a vertical axis; (iii) a telescoping arm extending horizontally from said body, said arm being variable in length by telescoping movement thereof; (iv) gripping means pivotably supported intermediate its length at the outer end of said arm for pivotal movement about a vertical axis and including gripping elements at each end thereof; (v) workpiece engageable means adapted to engage workpieces for movement between said work support station and said workpiece storage area, said workpiece engageable means having grippable elements thereon, each of said gripping elements of said gripping means being configured and dimensioned to grip said grippable elements of said tool members and of said workpiece engageable means; and (vi) drive means for effecting movement of said body on said base, telescoping movement of said arm, and movement of said gripping means to grip and release said tool members and said workpiece engageable means, said drive means being controlled by said control means.
Claim 3
Dependent Claim
63 words
The combination in accordance with claim 1 wherein said workpiece storage area has at least two stations, one of which is for workpieces before working thereon in said machine tool and the other of which is for workpieces after working thereon, and wherein said robot assembly is operable to effect movement of workpieces between said support station and each of such storage stations.
Claim 4
Dependent Claim
47 words
The combination in accordance with claim 1 wherein there is included a standby station for said workpiece engageable means and said robot assembly is operable to effect release and engagement of said workpiece engageable means at said standby station in response to operation of said control means.
Claim 5
Dependent Claim
38 words
The combination in accordance with either of claims 1 or 2 wherein said workpiece engageable means has a pair of grippable elements adapted to be engaged by the gripping elements at the opposite ends of said gripping means.
Claim 6
