Each wheel comprises a circular pitch plate (42) providing four sets of six notches (N1, N2, N3, N4) spaced uniformly around its periphery; the notches form semi-circular recesses (R1, R2, R3, R4) of different diameters to accommodate different sizes of workpiece, and the recesses are all centered on a common pitch circle (P) of the pitch plate. The wheel comprises also a picker plate (44) comprising six lobes (66) which are spaced uniformly about the axis of the wheel and form radially-projecting edges (68) positioned adjacent to the notches of any selected one of the four sets of notches.

  • Patent number: 4782567
    Abstract: A system for transferring, positioning and machining a workpiece includes a transfer device for transferring the workpiece to a prescribed position, a positioning device disposed in the prescribed position for positioning the workpiece, a machine tool for machining the workpiece, and a delivery robot disposed in the prescribed position for delivering the workpiece to the machine tool. The positioning device is used to position workpieces successively. Therefore, it is not necessary to provide positioning devices which would otherwise be associated with respective workpieces. The positioning device includes a positioning pin which is displaceable toward and away from a workpiece. Since the positioning pin is not held against the workpiece at all times, the positioning pin is prevented from being damaged or broken by physical interference with surface irregularities of the workpiece.

  • Patent number: 4747193
    Abstract: An apparatus for supplying a pallet to a machine tool has two rows of pallet supports and a pallet carrier between the two rows. The two rows of pallet supports consist of one or more modules so that a change of the number of pallet supports can be easily achieved. The pallet carrier moves along and at a right angle to the two rows, and can be positioned under a desired pallet. The pallet carrier lifts the desired pallet and transfers it to the machine tool by only linear movement.

  • Patent number: 4738387
    Abstract: The invention is concerned with the design of processing stations for the processing, by welding technology, of semi-finished vehicle body subassemblies (5) within the framework of a flexible manufacturing system. Thereby, frame-like work piece carriers (1) with support members (4) are used for loose positioning of components of the subassemblies (5), where the work piece carriers (1) are also capable of accepting differently configured subassemblies. The transfer line (9) is not planned as a single line, but includes only the input station (10), the work position (6) and the output station (11). Next to these stations (10, 11), storage stations (14) are arrayed, which are connected with one another by a transport system (20) which crosses the transfer line (9). In this manner it is made possible to store the work piece carriers (1) with the processed subassemblies (5) or to bypass the next work station if it is not capable of receiving (a work piece carrier), or is out of order.

  • Patent number: 4730382
    Abstract: An integrated factory system affords precision machining and inspection of aircraft turbine blades, as well as other metal parts having two generally opposite principal surfaces. It uses only two stages of chucking by the meltable matrix method. After embedding one of the surfaces in the first chuck, which positions the blank relative to a plane of reference, the other surface is machined and inspected according to programs relative to that plane. Without release from the first chuck, the part is transferred to a second chuck for embedding the machined principal surface relative to a second parallel plane of reference a precise distance from that of the first chuck. Machining and inspection is now completed relative to this second plane of reference.Improved matrix chucks are provided, as well as new chucking apparatus which establishes the planes of reference.

  • Patent number: 4722653
    Abstract: An automated assembly facility includes a random storage facility for each assembly line conveyor and associated series of assembly stations. The assembly line conveyor is located between the random storage facility and the series of assembly stations. A first conveyor is coupled between plural sources of carriers and the random storage facility. The random storage facility is coupled to the assembly stations by a transfer conveyor so that carriers can be transferred directly from random storage to an appropriate assembly station, obviating the need for the assembly line conveyor to cooperate in this transfer. The layout leaves the assembly station accessible from three sides. Efficient space use is achieved by providing one access aisle for each pair of assembly lines; random storage facilities of two lines are directly adjacent each other.

  • Patent number: 4712283
    Abstract: A system including a vertical turning machine and at least two auxiliary stations, such as a control, loading and discharge station, and a waiting station, has a drive mechanism for moving the workpiece platforms (pallets) between respective equipment supports (pallet supports). The drive mechanism includes a hydraulic cylinder housed in a diametral through seat in the upper part of the turning machine pallet support and located between respective pallet supporting straight guides. It includes a T-shaped hook member projecting from a cursor, located close to one end of the seat, and fixed to upper passes of a pair of chains driven by sprockets which form part of a carriage. The carriage is fixed to the end of a piston shaft projecting from the hydraulic cylinder. The advance of the piston shaft causes the carriage to project partly outwardly from the perimeter of the pallet support towards an auxiliary station.

  • Patent number: 4697318
    Abstract: An adaptable machining system includes a plurality of transport units mounted on a machine base with each transport unit carrying a system-standard mounting plate that receives a tool-carrying module. Each tool-carrying module includes a machining tool and associated motor mounted on a system-standard tooling plate which, with the mounting plate of the transport unit, define a system-standard tooling interface. The transport units, under the coordinated control of a system controller, advance their respective tooling modules to and from a work piece to accomplish their machining function. The mounting plate of each transport unit establishes an orthogonal reference system relative to the operating axes of the machine so that the position of each tool carried on a tooling module is known relative to the operating axes of the machine.
