A workpiece handling system is disclosed. The system includes a generally centralized pallet handling stand, and a number of pallet-accepting stations. These stations can be associated with machine tools such as vertical turret lathes or horizontal boring machines or other machine tools. The station can also be a relatively simple pallet storage station. Alternatively, the station can comprise a cart upon which a pallet can be deposited for movement to other parts of the factory. The pallet transfer station includes a foundation, and a base rotatable upon the foundation. A ram is translatably slidable on the rotatable base. A latch is reciprocable upon the ram. To transfer a pallet from one station to another, the base is angularly indexed into general alignment with the first work station. A shot pin device effects final, precise alignment of the ram with the work station. The ram is then radially advanced into engagement with the work station. A Vee-shaped member effects alignment of the work station with the ram. The latch is then advanced to the work station, and engages the pallet. The latch then draws the pallet over a safety latch and into a relatively centralized position on the ram. The ram is then withdrawn to a relatively centralized position on the base. The base can then be angularly indexed into general alignment with the other work stations. |

DETAILED DESCRIPTION While the invention will be described in connection with a preferred embodiment, it will be understood that it is not intended to limit the invention to this embodiment.
On the contrary, it is intended to cover all alternatives, modifications and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
Turning first to FIG.
1 there is shown an embodiment of a novel system 20 for handling a typical workpiece 21 which is mounted on a pallet 22.
The workpiece 21 is rigidly secured to the pallet 22 by pallet-carried chuck mechanisms 23 or other known means.
In accordance with a broad aspect of the invention, this system 20 can be used to move the workpieces 21 between individual machine tools.
Here, for example, a vertical turret lathe 24 is associated with a horizontal boring machine 25 to perform various machining operations on desired surfaces of the workpiece 21.
This vertical turret lathe 24 can be of the type offered by Giddings & Lewis Machine Tool Company of Fond du Lac, Wisconsin, and can have a work table of up to 84 inches in diameter.
The horizontal boring machine 25 can also be of the type offered by Giddings & Lewis Machine Tool Company.
It will be understood that machine tools of other types, or machine tools offered by other manufacturers, can be used and associated with the novel workpiece handling system 20 if desired.
These machine tools 24 and 25 can be numerically controlled, as by programmable computers (not shown) or other known means.
When they are so controlled, each machine tool 24 and 25 can automatically perform a series of operations on the workpiece 21.
Conveniently located near the system 20 is a control panel 26, here mounted upon a post 27.
This control panel 26 provides a number of actuators for operating the system to transfer the workpieces 21 between the various work stations, storage stations and carts.
This control panel requires a system operator to be located near the control panel 26, where he can observe the system 20 and the related machine tools 24 and 25 and so insure safe and efficient system operation
