Abstract

A system for coordinating the transfer of reactant chemicals is provided which comprises: first and second reactant chemical carriers adapted for positioning at corresponding first and second loading stations, wherein the first loading station accepts placement therein of the first reactant chemical carrier but blocks placement of the second reactant chemical carrier, and the second loading station accepts placement of the second reactant chemical carrier but blocks placement of the first reactant chemical carrier.

SYSTEM FOR COORDINATING THE TRANSFER OF REACTANT CHEMICALS

BACKGROUND

Technical Field

The present invention relates to the loading of reactant chemicals and more particularly, to a system for transferring reactant chemicals to or from designated carriers and respective loading stations.

Background of the Art

Various two part adhesive systems are known. For example, U.S. Patent No. 4,923,902 discloses a two-part adhesive system containing A and B components. When these components are mixed the adhesives harden into a solid mass.

In industrial processing it is often required to carry the components in individual containers to or from respective loading stations where they are be transferred by pump either from or into the container. The individual components are transported in specialized carriers, or "totes," by fork-lift trucks.

It can readily be appreciated that, should the carrier for one reactive component (e.g., the "A" component) be inadvertently confused with the carrier of the other reactive component (the "B" component) and taken to the opposite loading station, severe damage could occur by the components mixing together in the same feed lines and subsequently hardening within the pumps and piping, thereby shutting down the network of equipment and possibly affecting the operation of an entire plant.

Various solutions, such as color-coding, have been considered, but each has had unacceptable drawbacks. What is needed, then, is a method and apparatus which prevents the carrier of one component of a two part reactive chemical system from being positioned in a loading station intended for the other component.

SUMMARY

A system is provided herein for coordinating the transfer of reactant chemicals. The system comprises first and second reactant chemical carriers adapted for positioning at corresponding first and second loading stations, wherein the first loading station accepts placement therein of the first reactant chemical carrier but blocks placement of the second reactant chemical carrier, and the second loading station accepts placement of the second reactant chemical carrier but blocks placement of the first reactant chemical carrier.

The first carrier includes a first container for holding a first reactant chemical, the first container being fastened to the top of a substantially quadrangular shaped first platform. The first platform has at least one, and preferably two, rectilinear channels extending from a proximal edge of the platform to a distal edge of the platform and defining a longitudinal direction. The distal left corner and the diagonally opposite proximal right corner are each characterized by a distinctive, similarly shaped cut-away portion.

The second carrier is shaped and configured to conform to a mirror image of the first carrier.

The first loading station includes a base and an orientation plate having...
