Abstract

A baggage conveyance tray suitable for a sorting conveyor system for conveying baggage at airports has raised wall plate portions protruding on the front and rear both end portions of the tray in the length (conveyance) direction thereof extending in the right-left width direction of the tray. A baggage placement surface located between the front and rear both raised wall plate portions is concave along the length direction such that the central portion in the right-left width direction is lowered while the right and left both sides are raised. Elongated protrusion portions extending along the right-left width direction of the tray are disposed on the baggage placement surface at intervals in the length direction of the tray.

First claim

What is claimed is:

1. A baggage conveyance tray comprising:
front and rear raised wall plate portions protruding along a right-left width direction at front and rear end portions in a length direction, which is a conveyance direction;
a baggage placement surface between the front and rear raised wall plate portions, wherein elongated protrusion portions along the right-left width direction of the tray are provided on the baggage placement surface so as to protrude at intervals in the length direction of the tray;
the elongated protrusion portions on the baggage placement surface having a flat top surface parallel to a front-rear length direction of the tray, and the flat top surface is formed with a protruding surface portion thereon; and
the protruding surface portion is encircled by an annular protruding portion, and linear protruding portions in the right-left width direction of the tray are formed in parallel inside the annular protruding portion.

2. The baggage conveyance tray according to claim 1 , wherein the baggage placement surface has front and rear ends formed with substantially triangular inclined regions in a plan view, the triangular inclined regions having the baggage placement surface raised toward the raised wall plate portions within a range that does not exceed the height of the right and left sides of the front and rear ends.

5. The baggage conveyance tray according to claim 1 , wherein the front and rear raised wall plate portions are protruded at positions entered inside from the front and rear ends in the length direction of the tray and so as to be away inside from the right and left sides of the tray, and bottom surface side corner portions of the front and rear ends in the length direction of the tray are formed with recessed step portions, and the recessed step portions are formed with positioning recessed portions to which at least upper end portions of the front and rear raised wall plate portions of a lower tray are fitted at the time of stacking the tray.

6. The baggage conveyance tray according to claim 1 , wherein the tray is solidly and integrally molded with synthetic resin, and the baggage placement surface is formed with a depressed portion, and a cap is fitted and fixed to the depressed portion in a state where an information chip capable of contactless detection is accommodated within the depressed portion.

7. The baggage conveyance trays according to claim 1 , wherein the baggage placement surface is concave along the length direction such that a central portion in the right-left width direction is lowered and right and left both sides are raised.
