Abstract

Abstract A multi-part tray is provided to carry a plurality of objects in precise and accurate array through a process device. The tray parts are each fastened to a flexible plate and also to a conveyor. The conveyor is caused to travel a circuitous route around convex curves which thereupon splay the tray parts apart beneath a loading station and also beneath an unloading station where the objects are slidably moved onto or removed form the tray. A plurality of loading and unloading fingers slide in corresponding grooves in the bottoms of the tray-parts and beneath the objects.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 135 words
A device for holding a wide variety of products in accurate location for subsequent operation thereupon, said device including: at least one pocket plate having a plurality of holding members; each holding member having a side wall, two of said holding members having finger-receiving grooves therein, at least one loading finger and at least one unloading finger arranged to slide in each groove, laterally flexible, axially rigid spring plates secured to each of said holding members, so as to retain said holding members in precise location with respect to each other when said flexible plate is disposed in a single plane, but which permits said holding members to splay open or move away from each other when carried around a circuitous path prior to said loading and after leaving the area of the unloading fingers.
Claim 2
Independent Claim 135 words
A device for holding a wide variety of products in accurate location for subsequent operation thereupon, said device including: at least one pocket plate having a plurality of holding members; each holding member having a side wall, two of said holding members having finger-receiving grooves therein, at least one loading finger and at least one unloading finger arranged to slide in each groove, laterally flexible, axially rigid spring plates secured to each of said holding members, so as to retain said holding members in precise location with respect to each other when said flexible plate is disposed in a single plane, but which permits said holding members to splay open or move away from each other when carried around a circuitous path prior to said loading and after leaving the area of the unloading fingers.
Claim 3
Dependent Claim 30 words
A device of claim 1 wherein said flexible plate is metal and is fixedly secured to each of said holding members, and said holding members are secured to a conveyor.
Claim 4
Dependent Claim 12 words
A device of claim 2 wherein said conveyor is a chain belt.
Claim 5
Dependent Claim 12 words
A device of claim 2 wherein said conveyor is a timing belt.
Claim 6
Dependent Claim 15 words
A device of claim 1 wherein said loading and unloading fingers are flexible, metal strips.
Claim 7
Dependent Claim 38 words
The device of claim 3 wherein the flexible rigid plate is fastened to a plurality of links in the chain belt and all of the holding members in each pocket plate are fastened to a single, flexible plate.
Claim 8
Dependent Claim 22 words

Claim 10
Dependent Claim 24 words
The device of claim 8 wherein the holding member presses against the side wall of the products, substantially above the base of the products.
Claim 11
Dependent Claim 28 words
The device of claim 9 wherein the clamping pressure against the side wall of the product is applied between 25 to 60% of the height of the product.
Claim 12
Dependent Claim 28 words
The device of claim 9 wherein the clamping pressure against the side wall of the product is applied between 40 and 45% of the height of the product.
Claim 13
Dependent Claim 26 words
The device of claim 9 wherein the clamping action of the holding member against the side wall provides dimensional integrity in both machine and cross-machine direction.
Claim 14
Dependent Claim 27 words
The device of claim 1 including at least one index pin in each pocket plate to insure accurate orientation of the pocket plate with subsequent operating devices.
