Method and apparatus for ultra-clean seeker transportation and storage
First Claim
1. An apparatus comprising:
- a structure configured to receive and retain a product storage container having rollers that (i) are mounted on a bottom surface of the product storage container, (ii) rotate around substantially parallel vertical axes, and (iii) arranged in one or more pairs of rollers;
wherein the structure comprises a rail positioned under a space, the rail configured to be received between the rollers in each of the one or more pairs of rollers, the rail comprising edges configured to be received by grooved sidewalls of the rollers in each of the one or more pairs of rollers;
wherein the rail is configured to allow the rollers in the one or more pairs of rollers to roll along opposite sides of the rail, and wherein the rail is configured to support the product storage container within the space above the rail through contact with the rollers along the edges of the rail.

Abstract
An ultra-clean transportation and storage system includes a product storage container with a base having product supports and a segmented lid enclosing the product supports. Rollers on the base have grooved sidewalls receiving a rail to support the product storage container and rolling along the rail edges. Lift-off hinges allow lid removal only after a predetermined rotation. Seals, a one-way breather valve, and a gas inlet allow the interior of the enclosure to be purged. A friction brake on the product storage container has an integrated O-ring contact surface and a housing enclosing complementary acme threads for moving the brake. A transfer cart includes a rail on the lift arm to support the product storage container during movement, and alignment and docking mechanisms on a transfer end effector of the lift are for docking with either a storage spaced on a storage rack or a transfer space on a pass-through.

11. A transfer cart comprising:
-
a vertical support mounted on a movable base; a lift arm movable along the vertical support; a rail mounted on the lift arm and positioned under a space, the rail configured to be received between rollers that (i) are mounted on a bottom surface of a product storage container, (ii) rotate around substantially parallel vertical axes, and (iii) are arranged in one or more pairs of rollers, the rail comprising edges configured to be received by grooved sidewalls of the rollers in each of the one or more pairs of rollers, the rail configured to allow the rollers in the one or more pairs of rollers to roll along opposite sides of the rail, the rail configured to support the product storage container within the space above the rail through contact with the rollers along the edges of the rail; and a transfer end effector on an end of the lift arm, the transfer end effector configured to enter a front of a product container storage space within a product container support structure and vertically and horizontally align an end of the rail on the lift arm with an end of a rail on the product container support structure. - View Dependent Claims (12, 13)

14. A transfer cart comprising:
-
a vertical support mounted on a movable base; a lift arm movable along the vertical support; a rail mounted on the lift arm, the rail configured to be received between rollers that (i) are mounted on a bottom surface of a product storage container, (ii) rotate around substantially parallel axes, and (iii) are arranged in one or more pairs of rollers, the rail comprising edges configured to be received by grooved sidewalk of the rollers in each of the one or more pairs of rollers, the rail configured to allow the rollers in the one or more pairs of rollers to roll along opposite sides of the rail, the rail configured to support the product storage container; and a transfer end effector an end of the lift arm, the transfer end effector configured to enter a front of a product container storage space within a product container support structure and vertically and horizontally align an end of the rail on the lift arm with an end of a rail on the product container support structure; wherein the transfer end effector comprises a plurality of vertical rollers spaced to roll along angled corner faces of vertical uprights of the product container support structure to ensure depth-wise horizontal alignment of the end of the rail on the lift arm with the end of the rail on the product container support structure; and wherein the vertical rollers are configured to be received by vertical safety stop catches on the vertical uprights of the product container support structure to inhibit depth-wise horizontal movement of the lift arm when the vertical rollers are received by the vertical safety stop catches.

15. A transfer cart comprising:
-
a vertical support mounted on a movable base; a lift arm movable along the vertical support; a rail mounted on the lift arm, the rail configured to be received between rollers that (i) are mounted on a bottom surface of a product storage container, (ii) rotate around substantially parallel axes, and (iii) are arranged in one or more pairs of rollers, the rail comprising edges configured to be received by grooved sidewalk of the rollers in each of the one or more pairs of rollers, the rail configured to allow the rollers in the one or more pairs of rollers to roll along opposite sides of the rail, the rail configured to support the product storage container; and a transfer end effector on an end of the lift arm, the transfer end effector configured to enter a front of a product container storage space within a product container support structure and vertically and horizontally align an end of the rail on the lift arm with an end of a rail on the product container support structure; wherein; the transfer end effector comprises an additional roller and a spring-loaded movable gate; and each of the additional roller and the movable gate is configured to engage a counterpart structure on a horizontal beam of the product container support structure to prevent movement of the product storage container onto or off of the rail on the lift arm absent alignment of the end of the rail on the lift arm with the end of the rail on the product container support structure.
