Mobile Computing Scale

The drawing shows a scale for counting small parts by weighing. The scale has wheels 2 and it has a compact size that permits it to be moved easily to a station in a manufacturing plant, where parts are to be counted.

Three trays 3, 4, 5 are provided for handling parts of widely different weights with appropriate accuracy. Each tray is supported on a cantilever beam 6 that is mounted at its rightmost end to a support 7. Each beam has two spaced apart strain gages 9 and 10 that produce electrical difference signals, that very accurately indicate the weight on a tray.

A punched-card reader 12 receives a punched card that contains information about the part to be weighed and displays on a panel 14 the quantity of parts that are to be dispersed and other information, such as the identifying number of the part and the identification of a location where the part is to be found. By a control panel 15, an operator enters the number of parts that are to be weighed for a sample, selects the tray from which the electrical weight signals are to be accepted, and causes the sample weight to be entered into the system.

Thereafter, the operator adds parts to the tray and observes the quantity of parts on the display of panel 15. A weight-factor meter tells the operator whether the weight is outside the range of accuracy for the selected tray.

The apparatus carries storage batteries, a battery charger, and logic and arithmetic circuits for the counting and...
