  • Patent number: 8826925
    Abstract: An exemplary cleaning apparatus includes a cleaning member, a connecting member, a drying member, and a workpiece holder. The connecting member includes a main housing defining two opposite surfaces and two blocks received in the main housing. The main housing defines a first chamber and two second chambers communicating with the first chamber, each of the second chambers extending through to one of the two opposite surfaces and near to the other opposite surface. The cleaning member and the drying member are connected to the two opposite surfaces and communicate with each other via the first chamber. The two blocks are movable between the first chamber the second chambers, respectively. Each block defines an engaging surface, facing the other engaging surface. When the blocks move into the first chamber and the engaging surfaces engage with each other, the blocks shut off communication between the cleaning member and the drying member.

  • Patent number: 8261756
    Abstract: A rapid and effective means for decontaminating fouled oil-control booms is provided. The process involves washing the boom with pressured washing fluid, reorienting the boom to facilitate full inspection, and drying the boom. This can be performed in an assembly-line manner, using one or more conveyors to transport the boom sequentially to a washing area, an inspection area, and a drying area. Consequently, contaminated oil-control booms can be cleaned and redeployed rapidly and inexpensively during an oil release accident.

    Abstract: A method for removing exterior material from vials following a serpentine path through various steps of cleaning and drying. The movement of the vials may be limited to a predetermined path formed as an elongated opening in a sheet of material. The sheet may be replaced with a similar sheet with a different width of opening for bottles of differing sizes. The vials are rotated as they move along the path which may be accomplished by slight deviations in the straight sections of the elongated slot such as a zig-zag or sinusoidal wave. Changing the sheet can alter the number of straight path segments and thus the overall path of the vials through the equipment. The cleaning of the vials may include a washing with detergent, water rinsing, and air and vacuum drying. Air is drawn through the paths to produce a completely dry product. Liquid is removed from the vials' bottoms by a vacuum underneath the paths.

In one embodiment, the improvement includes immersing at least a portion of a part in a volume of a liquid solvent in a vapor degreaser while subjecting the portion to ultrasonic agitation to substantially remove excess resin. Several examples of solvents are provided, including ethanol, and Freon TMS. In a second embodiment, the improvement includes building the part on a layer of liquid resin supported by a volume of a dense, immiscible, and UV transparent intermediate liquid, and integratably immersing at least a portion of the built part in the intermediate liquid, and then either subjecting the immersed portion to ultrasonic agitation to substantially remove excess resin, or subjecting the immersed portion to UV light. Several examples of intermediate liquids are provided, including perfluorinated fluids, such as Fluorinert FC-40, and water-based salt solutions, such as solutions of magnesium sulfate or sodium chloride in water.

  • Patent number: 5014726
    Abstract: Apparatus for conveying article carriers (11) through a series of processing stations (T) in the form of tanks into which articles supported by the carriers are to be dipped has a row of lifting devices (13A-13H), each including an article carrier support (17) which defines a section of a horizontal processing track along which the article carriers (11) are movable in succession. The article carrier supports (17) are individually displaceable vertically between an upper position and a lower position (dipping position). When adjacent article carrier supports (17) are simultaneously in the upper position, an article carrier on one of the article carrier supports can be fed over to the other. A sensor (K) triggers lowering of said other article carrier support to the lower position in response to the reception of the article carrier by that article carrier support.

  • Patent number: 4893642
    Abstract: Apparatus for cleaning/deburring manufactured parts, each part having an established axis of rotation, includes a conveyor operable to convey the parts in succession in intermittent step-by-step movement to a cleaning/deburring station and a drying station. At each of the cleaning/deburring and drying stations the part is driven in high speed rotation about its axis by a part rotating device. At the cleaning/deburring station the rotating part is sprayed with high pressure fluid and at the drying station high velocity air is discharged tangentially against the rotating part to strip residual fluid from the part. The spray nozzle assembly can be stationary, or can take the form of a transversing assembly for reciprocating movement along the longitudinal length of the part. Additionally, the transversing assembly can include rotation of the nozzle assembly about an axis as the nozzles are reciprocated longitudinally.

  • Patent number: 4890633
    Abstract: An apparatus for treating a workpiece by a pre-treatment process before painting or for a washing process in an electrodeposition treatment. The workpiece is transferred through a series of treating zones. The apparatus has a plurality of hanger disposed on the right and left sides relative to the advanceing direction of the workpiece, a pair of hanger travelling rails, a hanger carrying mechanism and a plurality of hanger lifting assemblies disposed on the right and left sides of the advancing direction. Each rail consists of fixed rail portions and movable rail portions. Right and left lifting assemblies are controlled in cooperation, simultaneously or alternately, to move the hangers up and down allowing the workpiece to tilt or oscillate within the treating zone.

  • Patent number: 4827954
    Abstract: A work transfer system conveying a work basket in a programmed sequence to the processing tanks of an assembly thereof at various positions on a work bench. The system acts to transfer the basket to a selected tank and to properly orient the basket with respect to this tank before lowering the basket therein for processing for a given dwell period, at the conclusion of which the basket is hoisted from the tank and transferred to another tank where the procedure is repeated. Running parallel to the front side of the bench is a rail on which a robot rides, the robot supporting a hoist carriage which can be raised or lowered. Cantilevered from the carriage is a main arm articulated by an elbow shaft to a forearm that extends over the bench. The forearm is joined by a hand shaft depending therefrom to a hand that engages the handle of the work basket. A main arm motor acts to rotate the elbow shaft and thereby swing the forearm to a position generally aligning the basket with a selected tank therebelow.

  • Patent number: 4493333
    Abstract: A mechanized work transfer system in which a robot assembly riding on a horizontal rail and driven by an external motor acts to convey a basket carrying work along a row of processing stages on a work bench. The assembly includes a robot provided with an elevator operated by an internal motor which serves to lower the basket at each stage on the work bench and to deposit it into a processing tank for a predetermined dwell period, after which the basket is hoisted out of the tank and transferred to another stage where the procedure is repeated. To render the assembly substantially immune to corrosive vapors emanating from the tanks, the robot housing is sectioned into left and right compartments, the left compartment being reserved for those moving and stationary components which can be fabricated of corrosion-resistant materials.
