Abstract
Disclosed in a span adjusting device for an automatic weighing apparatus of the type in which the load of a weighing hopper containing articles to be weighed is applied to a corresponding weighing mechanism through means of a support member adapted for supporting the weighing hopper, and in which the weight is derived as the magnitude of the output signal from a displacement sensor provided on the weighing mechanism. The span adjusting device comprises a reference weight rest which is secured to the support member and on which a reference weight may be placed so that the span weight of the reference weight is applied to the weighing mechanism through means of the support member, and a vertical displacement mechanism, the mechanism including an operating bar passed through the reference weight rest and vertically movable therethrough in such a manner that the reference weight is placed on the end of the operating bar when the bar is located above the weight rest and the reference weight is removed from the end of the operating bar and placed on the weight rest when the bar is moved to a position below the weight rest. The arrangement makes it possible to simplify a span adjustment, and to perform a more accurate span adjustment in a shorter amount of time.
