A stackable carrier assembly, carrier stacking system, and method of storing carrier assemblies is disclosed. The carrier assembly includes a base member presenting a load surface and opposite facing transfer surface. A plurality of carrier trolleys extend transversely from the load surface to engage conveyor tracks. A plurality of track sections are coupled to the load surface for receiving the carrier trolleys of another carrier assembly. The track sections are vertically aligned with the carrier trolleys. In a power and free or friction drive conveyor system, a lift device and telescoping arm can lift and stack the carrier assemblies so that track sections of one carrier assembly receive the carrier trolleys of another carrier assembly. In an overhead conveyor system, one carrier assembly can hang from the track sections of another carrier assembly.

Stackable carrier assembly, system, and method for storing carrier assemblies

The present invention is directed to a carrier and conveyor system that permits the carrier to be driven by at least two different types of conveyors or drive assemblies, including a power and free conveyor. The system includes a plurality of carriers, first and second areas, a power and free conveyor assembly, and a friction drive assembly. The power and free conveyor drivably engages the first and second carriers when the carriers are in the first area and is out of driving engagement with the carriers in the second area. The friction drive assembly is engageable with each carrier when the carriers are in the second area and out of driving engagement with each carrier when the carriers are in the first area.

Carrier conveyor system

A system for transporting articles along a treatment path in a treatment area. The conveyor system includes a conveyor and a plurality of pendulums. The conveyor includes first and second drive segments laterally spaced from and parallel to one another. The pendulums include first pendulums moving along the first drive segment and second pendulums moving along the second drive segments in aligned and opposed pairs. Further features of the invention include a guide assembly having a first element coupled to move with a carrier assembly and a second element engaging the first element to stabilize the rotational orientation of the carrier assembly. Other features of the present invention include a conveyor system configuration that facilitates transportation of articles about horizontal curves as well as a unique pendulum configuration particularly suited for use with the invention.

Conveyor system for article treatment

A conveyor assembly including a conveyor defining a conveying direction and a carrier assembly operably coupled to the conveyor. The carrier assembly includes a carrier frame, a rotating mechanism coupled to move with the carrier and having a rotatable shaft with a rotary axis parallel to the conveying direction. The carrier assembly further includes a workpiece mounting frame coupled to rotate with the rotatable shaft. The invention is also directed to a workpiece treatment system having the conveyor assembly described above as well as a method of using the conveyor assembly to convey workpieces through a treatment system.

Workpiece treatment system and conveyor assembly

The present invention is directed to a pallet conveyor system that includes a pallet assembly having a pallet and a workpiece coupled to the pallet, a production area where a production task is performed on the workpiece, and a delivery area wherein the pallet assembly is moved to or from the first production area. The pallet conveyor system also includes a first conveyor assembly to drive the pallet assembly through the first production area and a chain conveyor assembly to drive the pallet assembly through the first delivery area. The first conveyor assembly operably engages the pallet in the first production area but not in the delivery area. Conversely, the chain conveyor assembly drivably engages the pallet assembly in the delivery area but not in the production area.
