  • Patent number: 4930258
    Abstract: The present invention provides an integrated buffing and grinding system. The system includes a first conveyor for transporting an article to a grinding station. The article is grasped by a robot and brought into and out of contact with an abrasive surface of a sanding device. The article is then transferred by the robot to a second conveyor. The article travels along the second conveyor to a shuttle assembly. The article is then transferred by the shuttle assembly to a moveable table of a buffing device. The moveable table moves the article into and out of contact with a buffing wheel of the buffing device. The article is then transferred by the moveable table to the shuttle assembly. The shuttle assembly transfers the article to the second conveyor. The article travels along the second conveyor to an unloading station where it is unloaded.

  • Patent number: 4928386
    Abstract: The invention relates to a mounting device for the automatic assembly of prefabricated parts or such as aggregates to a car body from below. For this purpose the aggregates 14 are arranged centeredly, but removably on installation plates 12, which are mounted liftably and in the lifted position floatingly yielding on a mounting frame 9. The aggregates 14 are penetrated by vertical centering journals of the installation plates 12. The protruding part 24 of the centering journal 17 is tapered in its face region and serves to enter an assigned centering bore of the car body 1 while the mounting frame is lifted. As the installation plate 12 is mounted floatingly on the mounting frame 9 in this phase, the aggregate arranged on it moves automatically into an assembly position in which an automatic process can take place.

  • Patent number: 4910858
    Abstract: An automatic coil winding and finishing machine. First and second bobbin conveying devices of the apparatus are capable of reciprocating on linear lines while holding coil bobbins, and of stopping the coil bobbins at predetermined positions. The first conveying devices allow the coil bobbins to be fed from a feeding device to a coil winding device and then to be discharged therefrom after the completion of the coil winding process. The second conveying device receives the coil bobbins from the first conveying device, and then allows them to be subjected to coil finishing processes in cooperation with devices for the coil finishing processes, as the coil bobbins remain held by the second conveying device. The intervals at which the conveying devices hold the coil bobbins may be determined in such a manner that the intervals are reduced when the coil bobbins are transformed from the first conveying device to the second conveying device.

  • Patent number: 4901412
    Abstract: An automated machine tool assembly has a plurality of work stations between which pallets with workpieces mounted on them can be moved for the performing of various machine tool operations on the workpieces. The pallets slide on slide rails, and during their movement an upward force is exerted on the pallets which is sufficient to reduce the frictional drag between the pallets and the slide rails, but is insufficient to lift the pallets off the slide rails.

  • Patent number: 4894896
    Abstract: Precision centering device useful for positioning items in a predetermined position has first and second halves which are held within a frame. The first and second halves are maintained against retaining walls within the frame by resilient material. The bottom portion of the halves extends from the bottom of the frame and each has a tapered edge which face each other in order to hold the item to be positioned. The top of the halves are maintained within the frame by a resilient structure which allows the halves to move in a vertical position. The halves which accomplish the positioning do not have to be made from precision parts. As the parts wear the centering precision is maintained since the parts are mirror images of each other made from a common piece of stock material.

  • Patent number: 4890371
    Abstract: A pallet changer device is associated with a milling or machining device and has a table that indexes 180.degree.. A pallet is held in an upright position for loading of fresh workpieces, while machining is carried out automatically on workpieces on a similar pallet. When the machining is complete, the table indexes 180.degree. exposing an available station, and an arm retrieves the pallet of machined parts and moves it onto the table. Then the table is indexed again, and the pallet of fresh workpieces is moved to a work station at the machining device. A wash cycle is carried out on the pallet of workpieces, now suspended beneath the inverted table. After the cycle, the table is inverted placing the cleaned finished workpieces upright. These are removed from the pallet and replaced with fresh workpieces.

  • Patent number: 4878524
    Abstract: A woodworking machine has a series of stations spaced along a conveyor having a clamp support for holding flat wood parts and passing the edges through the stations which include cope stations as well as others. The coping stations have a tool unit with a stack of tools mounted on a common spindle. The tools in each stack at the several stations are interrelated such that the cuts of the individual tools can be combined to form different final profiles in a wood part moving through the several stations. The particular cuts in the profile line are analyzed and interrelated to define basic cuts which can be combined to form the final profiles. One tool of each tool stack provides a particular cut, and by precise positioning of the individual tools, the combination of sequential cuts provide the final profile. Each tool may form a complete cut, may overlap a previous cut to form a continuation of such previous cut or may form a cut which includes only a portion of its cutting face.
