The test object container holder of the present invention comprises a holder body having a container storage portion, a first ring groove, and a second ring groove, and an indication ring engaged in the outer circumference of the holder body. The test object container holder conveyer apparatus of the present invention includes a test object container holder including a holder body and an indication ring, holder conveyer, for conveying the test object container holder, a sensor for detecting and ...

The invention provides a conveyor for conveying items along a longitudinal track comprising: at least one shuttle beam engaged on said track for longitudinal movement therealong, each shuttle beam including a longitudinal rack with engagement teeth, and drive mechanisms spaced along the track for engaging and propelling each shuttle beam. Each drive mechanism comprises a pinion gear complementary to the rack for synchronized movement of the pinion gear and the rack by engagement between the enga...

Pallet conveyor intersection apparatus having a central portion and plural conveyor portions connected to the central portion. Each of the conveyor portions has a pallet way along which pallets can be driven. The pallet ways of at least two of the conveyor portions are disposed at different levels, and the central portion is configured so that it can vertically displace a pallet, situated on the central portion, between levels corresponding to the different levels of the pallet ways of the conve...

An article carrier system in which articles are transferred between pallets and support means particularly useful in transfer systems where work articles are being processed in the way of machining and the like and being carried by conveyors, either on pallets or as a bare part, from station to station. An endless power driven, optionally reversible, conveyor is disposed vertically and has a plurality of pallet conveying buckets and a plurality of article conveying buckets arranged in a regular ...

In a production line small parts or conductor ends are transported by workpiece carriers from work station to work station in a production direction. First and second groups of work stations. First and second transfer devices move the workpiece carriers from work station to work station in the groups. An interchange device is connected between the two transfer devices, the first transfer device handing over the workpiece carriers to the interchange device and the interchange device feeding the w...

A corner track for an automated lab conveyor system includes a first length of track connected at its upstream end to the downstream end of a second length of track. Each track length includes a pair of guide rails on opposite sides of an operable transport surface for moving a specimen carrier thereon. First and second auxiliary transport surfaces are lined with the first and second track lengths and serve to slow the movement of a specimen carrier as it approaches the corner connection.

An endless accumulating conveyor has upper and lower guide rails for supporting pallets. An endless roller chain has an upper run extending along the upper guide rails and a lower run extending along the lower guide rails. A dogging device on each pallet is engageable between the rollers of the chain to move the pallet with the chain along the upper and lower runs. A friction clutch for the dogging device of each pallet causes the dogging device to release and slip past the rollers of the chain ...

The actuating device comprises an actuator arm (11) pivoting about a rotating axle (12) and driving two devices (15, 16) for displacing pallets. These devices also pivot and are laterally displaced along the axles (24, 25) integral with the arm (11) and are located at different distances from the rotating axle (12). The first displacement device (15) consists of a comb (26) with regularly spaced lateral notches. The second displacement device (16) consists of a comb (30) with one lateral notch a...

A workpiece carrier (10) for conveying one or more workpieces with a belt conveyor (12,18) is described, which reduces the production cycle time of an industrial manufacturing plant. The workpiece carrier (10) includes energy storage devices (24,32,38), into which energy of motion of the workpiece carrier (10) is transferred when the workpiece carrier is braked against or stopped on the belt conveyor (12,18). The energy storage devices each include a coupling element (28,36), advantageously a fr...

An endless roller chain conveyor of the over/under type supporting carriers or pallets which independently travel along the horizontal runs of the conveyor upon demand, while the roller chain is allowed to continuously run at a constant speed. The chains are multi-strand roller chains. The carriers or pallets may be stopped and held along the horizontal runs of the conveyor (both top and bottom) using mechanically driven stop assemblies located at required load, unload, holdback, or workstation ...
