Modular scanner component mounting system for checkstand

摘要

An arrangement for a tunnel scanner includes a chassis with a first data reader structure and a second data reader structure attached thereto. The first and second data reader structures include data readers that are pre-positioned before the first and second data reader structures are attached to the chassis. Indexing features of the first and second data reader structures cooperate with corresponding indexing features of the chassis to properly position the data readers relative to the chassis. In one assembly method, one or more data reader structures having pre-positioned data readers are shipped to an assembly location for a tunnel data reader. A chassis is either provided at or shipped to the assembly location. In one configuration, the data reader structures are indexed and attached to the chassis such that each data reader is placed at a desired location and orientation with respect to the chassis.

主权项

1. A method for assembling a tunnel data reader arrangement comprising:
receiving a first and second data reader structure at an assembly location where a tunnel data reader arrangement is to be assembled, wherein the first data reader structure includes a first data reader and the second data reader structure includes a second data reader; providing a counter structure at the assembly location; providing a chassis at the assembly location; forming a tunnel data reader arrangement at the assembly location by;
matching a first indexing feature of the first data reader structure with a corresponding first indexing feature of the chassis;attaching the first data reader structure to the chassis such that the first data reader structure extends upwardly relative to an uppermost, top surface of the chassis, wherein the first data reader is arranged in a first position at a first angular orientation with respect to the chassis;matching a second indexing feature of the second data reader structure with a corresponding second indexing feature of the chassis; andattaching the second data reader structure to the chassis such that the second data reader is arranged in a second position at a second angular orientation with respect to the chassis; and coupling the tunnel data reader arrangement to the counter structure.
