A system for leak testing industrial components, such as engine blocks, is disclosed and includes a conveyor system for transporting the engine components to and from a test area having a support surface. A robot is operable in the test area and includes a manipulator which engages and moves the industrial components. At least two leak test units are provided where each leak test unit includes a shuttle for receiving the industrial component from the robot and thereafter subjecting that industrial component to a leak test. Each leak test unit then generates a failure output signal in response to a failed leak test on the industrial component. Each leak test unit is movably mounted to the test area support surface between an operable position and an inoperable position. In its operable position the leak test unit is positioned in the test area to receive the industrial components from the robot and perform the leak test. Conversely, in its retracted position, the leak test unit is positioned outside of the test area for maintenance, repair or the like. A robot control circuit controls the movement of the industrial components by the robot between the conveyor system and one or more of the selected leak test units in response to at least one control factor, such as a failure output from one of the leak test units.

An escapement is provided for use in conjunction with a conveyor having a frame which defines a plane on which articles are conveyed along a predetermined direction of movement. The escapement includes a housing which is pivotally secured to the conveyor frame about a first axis which is perpendicular to the predetermined direction of movement of articles on the conveyor. The housing includes a portion which is radially spaced from the first axis while a resilient shock absorber is disposed between the housing portion and the conveyor frame. A stop bar is movably mounted to the housing between an engage and a release position. In the engage position, one end of the stop bar is positioned above the conveyor plane so that, with the stop bar in the engage position, the stop bar prevents the passage of articles on the conveyor past the stop bar. Conversely, in its release position, the stop bar is retracted below the conveyor plane thus releasing articles for further movement on the conveyor past the stop bar.

A modular roller conveyor system is disclosed having a first and second pair of elongated vertical supports. The first pair of vertical supports are adjustably secured together so that the first pair of supports are spaced apart and parallel to each other at a user selected spacing between the first pair of vertical supports. Similarly, the second pair of vertical supports are also adjustably secured together so that the second pair of vertical supports are spaced apart and parallel to each other at the same user selected spacing. A first elongated rail is then secured to the upper end of one of the first pair of vertical supports and to the upper end of one of the second pair of vertical supports. A second rail is then secured to the upper end of the other of both the first and second pair of vertical supports so that the rails are spaced apart and parallel to each other. A plurality of spaced roller assemblies are then disposed between and supported by the rails thus forming the conveyor path along which articles are conveyed.

Modular roller conveyor system

A roller conveyor system is disclosed having a frame with a pair of spaced apart rails and at least one roller assembly having an elongated shaft. A first bearing assembly is secured to one rail while a second bearing assembly is secured to the other rail so that the bearing assemblies are aligned with each other and each bearing assembly includes an inner and outer race. The elongated roller shaft extends through the inner races of the bearing assemblies so that a flat formed on the shaft is radially aligned with the inner race of one of the bearing assemblies. A threaded fastener is then threadably secured to the bearing inner race and has one end adapted to abut against the shaft flat. With the fastener in abutment with the shaft flat, the other end of the fastener is substantially flush with an outer surface of the bearing race. An annular collar is then positioned over the outer surface of the bearing inner race and this collar has an inner diameter substantially the same as the outer diameter of the bearing inner race to thus hold the fastener in abutment with the shaft flat. At least one roller is then secured to an intermediate point of the shaft.

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.

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.

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. A single elongated link extends between the drive arm assemblies which ensures that the drive arm assemblies move in unison with each other.

Accumulating lift and carry conveyer system

A shuttle transfer assembly is provided for transferring parts between at least two conveyor lines. The shuttle assembly includes a base and a transfer table which is mounted to the base via a carriage assembly. A conveyor section is in turn mounted to the transfer table. The transfer table under program control is both rotated about a vertical axis and linearly displaced by the carriage assembly so that the conveyor section on the transfer table is aligned with a first selected conveyor line. A loader assembly on the transfer table selectively moves a number of parts from the first conveyor line onto the conveyor section. The transfer table is then moved so that its conveyor section is aligned with a second conveyor line. A unloader assembly then pushes the parts on the conveyor section from the transfer table and onto the second conveyor line.

Shuttle transfer assembly

An accumulating lift and carry conveyor system is disclosed which is particularly suitable tier conveying piston connecting rods. The conveyor includes a frame defining an arcuate conveyor section having a receiving end and a discharging end. A pair of arcuate, spaced apart and parallel stationary rails are secured to an upper end of the frame and the stationary rails are adapted to engage and support opposite sides of a workpiece. A pair of arcuate, spaced apart and parallel transfer rails are contained in between the stationary rails and are movable both between an upper and lower position as well as between a forward and a retracted position. An arcuate lift beam is disposed beneath the transfer rails while a slide assembly is disposed between the top of the lift beam and the transfer rails for enabling movement of the rails between their forward and retracted position. The lift beam is also movable between an upper and a lower position. In order to move the lift beam between its upper and lower position, a lift member is provided adjacent each end of and beneath the lift beam. These lift members are pivotal between a raised and lowered positions thus simultaneously moving the lift beam between its upper and lower position. A pair of link arms are connected via a bell crank between the lift members to ensure the lift members pivot in unison with each other.

Lift and carry accumulating conveyor system

An improved conveyor system and for a lift and carry type conveyor includes a pair of extruded stationary rails and a pair of extruded movable rails. The extruded stationary and movable rails are provided with T slots for modular installation. The improved stationary rail includes an elongated one piece body which is generally L shaped cross section having an upper and generally horizontal leg and a lower generally vertical leg. The improved movable rails include an upper end having a finger formed of thermo plastic wear material and a protection strip of the same material to protect against galling.
