Pneumatic Flat Plate Stock Carrier

Two pneumatic removable carriers are shown in the figures, in expanded condition, for transporting flat plate shaped items especially between work stations for automatic handling. The items can be magnetic recording disks.

An inner diameter carrier is shown in cross section in Fig. 1. The inner diameter carrier comprises a hub 1 with a leakproof covering 2 of an expandable material glued or otherwise fastened around its circumference. The hub 1 includes a passageway 3 for a fluid such as air. The fluid is directed to the passageway 3 to expand the leakproof covering 2 and thereby grip the item 4 via its center hole. A valve (not shown) can be used to control the pressurized input and the exhaust of the fluid to grip and release the item 4. The expandable material may be nitrite rubber. The material criteria for the leakproof covering 2 is to minimize contamination while being expandable by a fluid pressure with a recovery to original shape after pressure release.

The carrier can support a thin rigid item 5 on its periphery by providing a holder 6 of similar shape as the periphery of the item 5 and having a size that is larger than the outer periphery of the item. The peripheral holder 6 can be shaped as shown in cross section in Fig. 2. The holder includes a leakproof covering 7 of expandable material, as for the Fig. 1 carrier. A passageway B is provided in the holder for the input and exhaust of the fluid. As before, directing...
