  • Patent number: 6695568
    Abstract: A small loader has a frame, and drive tracks on opposite sides of the frame. The, drive tracks are mounted over drive sprockets and idler wheels to establish lengths of track at upper sides. The frame includes upright members at a rear portion for mounting a lift arm assembly made of two lift arms joined together. Each lift arm has a rear portion pivotally mounted on the upright portion of the frame and extending downwardly and forwardly to join side portions of the lift arms that are substantially parallel to the upper lengths of the respective tracks in a lowered position of the lift arm assembly. Actuators for pivoting the lift arm assembly are mounted on the frame, below the side portions and above the tracks, and extend generally parallel to both the side portions and the upper length of the tracks when the lift arm assembly is in a lowered position.

  • Patent number: 6692215
    Abstract: A presently-preferred embodiment of a lift and carrier assembly for a personal-transport vehicle comprises a lifting column, an actuator mechanism adapted to lift the lifting column, a pivot plate rotatably coupled to the lifting column, a platform fixedly coupled to the pivot plate, a cam follower coupled to the pivot plate, and a cam member being fixed in relation to the lifting column so that lifting of the lifting column causes the cam follower to contact the cam member thereby generating a contact force between the cam follower and the cam member. The cam follower is biased so that the contact force prevents the cam follower from being lifted when a weight acting on the platform is below a predetermined value thereby causing the pivot plate to rotate about the lifting column in response to the lifting of the lifting column.

  • Patent number: 6685422
    Abstract: The present invention generally provides a robot that can transfer workpieces, such as silicon wafers, at increased speeds and accelerations and decelerations. More particularly, the present invention provides a robot wrist associated with the robot arm for mechanically clamping a workpiece to a workpiece handling member attached to the arm. The wafer clamp selectively applies sufficient force to hold the workpiece and prevent slippage and damage to the workpiece during rapid rotation and linear movement of the handling member. In a particular embodiment, a clamp for securing silicon wafers uses a flexure assembly to position and hold the wafer with minimal particle generation and wafer damage. The clamp is designed so that the wafers are normally clamped near full extension of the workpiece handling member to deliver or pick up a wafer.

  • Patent number: 6659710
    Abstract: In a station for forming stacks of layers of articles, a horizontal supporting surface has a window for allowing a layer to pass freely therethrough. First pushing bars drive the layers along the support surface. A stationary descending ramp starts from the initial part of the window and extends downstream. A horizontal lower surface is situated after the ramp and under a horizontal upper surface, and forms a part of the support surface situated downstream of the window. An additional conveyor is associated to the window to restore cyclically a continuity in the support surface in the region of the window for the odd layers, and consequently to direct each odd layer toward the upper surface, and to allow the even layers to pass cyclically through the window. The even layers are consequently directed, due to gravity, onto the ramp. Second pushing bars move each even layer to the ramp and convey the even layer to the lower surface.

  • Patent number: 6655899
    Abstract: A frame apparatus that fits on the loader arms of a skid steer front loader. This frame apparatus serves as a platform upon which a plurality of hydraulically driven tools can be employed to grasp, lift, rotate, and transport heavy objects such as oil drums and telephone poles. The hydraulically driven tools are designed in a manner that allows them to be easily installed on, and removed from, the frame apparatus by one person. This is accomplished by having a frame member as part of the tool that slides over the end of the attached frame apparatus and is held in place by passing a pin through both of the attached frame members.

  • Patent number: 6648588
    Abstract: The present invention generally provides a processing system having a robot assembly which includes a multiple sided robot blade that can support a substrate on at least two sides thereof and associated methods to transfer one or more substrates in a processing system. An unprocessed substrate can be supported on the blade while a processed substrate is retrieved from a location to which the unprocessed substrate is to be delivered. The processing throughput rate is increased by reducing the movements required by the robot to exchange processed substrates and unprocessed substrates, thus decreasing the swap time.
