Processing apparatus and method of operation thereof
A manufacturing facility includes a storage facility and a production facility. Workpieces are located in the storage facility in temporary storage accommodations, and are moved between the storage facility and stations in the production facility by mobile carrier units. The temporary storage accommodations may be units having a generally circular lading envelope, and an hexagonal optimal packing density. The mobile carrier units may be automated guided vehicles and may include self-navigating software, and interactive communication with other guided vehicles to permit suitable routes to be chosen, or to permit obstacles to be avoided. The facility may include a workpiece retrieval apparatus used for transferring workpieces between the storage accommodations and the automated guided vehicles, or to other locations. The workpiece retrieval apparatus may be mounted on a bridge, and may include a multi-element raising and lowering array that is biased to oppose torsional deflection of the lifting member.
1. A transporting unit operable to carry a green tire within a tire manufacturing facility, said transporting unit comprising:
a lading seat supported on a chassis;
running gear mounted to said chassis;
said running gear being operable to cause said unit to move from place to place;
a control system operable to receive destination signals and to operate said running gear;
said lading seat including a lading interface upon which said green tire may be carried; and,
said lading interface having at least one degree of freedom of motion relative to said chassis;
wherein said unit includes a self-centering motion allowance member mounted in a load path between said chassis and said lading interface.
2. The transporting unit of claim 1 wherein said lading interface has two degrees of freedom of motion relative to said chassis.
3. The transporting unit of claim 2 wherein said two degrees of freedom permit longitudinal and lateral translation of said interface relative to said chassis.
4. The transporting unit of claim 1 wherein said self-centering allowance member includes a motion deterrent member, said motion deterrent member including a detent pit formed in one of said surfaces and engageable with the other of said surfaces to deter motion therebetween below a threshold level of dislodging force.
