Abstract: A conveyor system having an infeed conveyor section, an outfeed conveyor section, and a working conveyor section positioned in between and in line with the infeed and outfeed conveyor sections. The working conveyor section includes a base and a frame which is movably mounted relative to the base between a lower position and a raised position. In order to move the frame between its lower and raised position, a driver is rotatably mounted about a substantially horizontal axis to the base while an elongated drive link has one end pivotally connected to the frame and its other end pivotally connected to the driver at a position radially spaced from its axis. A drive mechanism selectively pivots the driver between first and second rotational positions which are spaced substantially 180 degrees from each other. In doing so, the coaction between the driver and the drive link moves the frame between its raised and lowered position.

Abstract: An industrial part washer is disclosed having a washer housing with an upper chamber, a lower chamber, and a fluid passageway connecting the chambers together. A fluid drain is connected to a lower chamber for draining fluid from it while a pump pumps a cleaning fluid into the upper chamber. A flood valve is positioned in the fluid passageway between the upper and lower chambers and this valve is movable between an open and a closed position. Parts are sequentially moved into a position adjacent the washer housing and are selectively loaded into the lower chamber, washed and, following completion of a wash cycle, subsequently unloaded from the lower chamber. A valve control closes the flood valve during the loading and unloading operations of the part into the lower chamber so that, during the loading and unloading portions of the wash cycle, the upper chamber at least partially and preferably completely fills with the cleaning fluid.

Abstract: A melt tank is disclosed having a plurality of cartridges wherein each cartridge is adapted to hold at least one molded part. An annular tank is provided having an open top while a substantially circular plate is coaxially rotatably mounted to the top of the annular tank. The circular plate includes a plurality of circumferentially spaced openings formed around its outer periphery wherein each opening is adapted to slidably receive and support one cartridge. The annular tank is filled with a heated liquid while a motor rotatably drives the plate with the molded parts immersed in the heated liquid. A robotic gantry selectively lifts the cartridges from the circular plate to enable the removal of finished melted out parts as well as the insertion of new molded over parts into the cartridges.

Abstract: An automotive framing system for positioning a lower body component and at least two upper body components together at precise positions relative to each other prior to fixedly securing the body components together. The framing system includes a conveyor for sequentially moving body preassemblies to a predetermined assembly station. A frame of integral construction is positioned around the body at the assembly station. A lifter at the assembly station lifts the lower body component and upper body components from the conveyor together with the frame to a predetermined elevated position in which the lower body component abuts against the upper body components. With the body preassembly positioned within the assembly station, clamps on the frame engage predetermined location points on the upper and lower body components to hold the upper and lower body components together at preset positions relative to each other whereupon the body components are fixedly secured together.

A lifter at the assembly station lifts the lower body component and upper body components from the conveyor to a predetermined elevated position in which the lower body component abuts against the upper body components. At least two turret assemblies are movably mounted to a ground support surface in a direction transverse to the conveyor. The turret assemblies are positioned at opposite ends of the assembly station and movable between an operative position in which the turret assemblies are aligned with the conveyor, and a standby position in which the turret assemblies are laterally spaced from the conveyor.

Abstract: A lift and carry accumulating conveyor is disclosed having a frame and a pair of elongated stationary rails attached to the frame such that the stationary rails are spaced apart and parallel to each other. A transfer rail assembly having a pair of elongated transfer rails is positioned in between the stationary rails and are movable relative to the stationary rails between both a raised and a lower position as well as between a forward and a retracted position. A pair of longitudinally spaced drive arm assemblies are pivotally disposed between the frame and a lower end of the transfer rail assembly. The upper end of each drive arm assembly abuts against the lower end of the transfer rail assembly so that, as the driver arm assembly is pivoted between a lower and an upper position, the drive arm assemblies simultaneously move the transfer rail assembly between its lower and raised positions.

Abstract: A conveyor system is disclosed for transporting workpieces. The conveyor system includes an elongated frame having an inlet end and an outlet end. A pair of sprockets are rotatably mounted to both the inlet end and outlet end while a pair of closed loop chains are mounted around the sprockets so that the chains are spaced apart and parallel to each other along the frame. A motor rotatably drives the sprockets and thus the chains along the frame. A plurality of pallets, each adapted to support a workpiece, are slidably mounted to the chains by rollers so that the pallets can move longitudinally with respect to the chains. A cam is secured to the sprockets at both the inlet and outlet ends of the conveyor frame. These cams engage a cam follower on the pallet to raise the pallets from a lower section of the chain to an upper section at the inlet end of the conveyor frame and vice versa at the outlet end of the conveyor frame.

Abstract: A device is disclosed for separating hydrocarbon products such as cutting oil from water. The device includes a receiving tank defining a reservoir which receives a mixture of water and oil. The oil floats above the water and thus forms an upper layer in the receiving tank. A skimmer skims the upper layer from the receiving tank and channels the skimmed portion to a pumping chamber. A venturi jet pump then pumps the skimmed portion from the pumping chamber to a settling tank which then separates the oil and water. The skimmer includes floats which vary the depth of the skimmer as a function of the liquid level in the receiving tank.
