Title:
QUANTITATIVE DISPENSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/246542
Kind Code:
A1
Abstract:
Provided is a quantitative dispensing system capable of accurately weighing out a target supply weight of a substance for weighing while taking into consideration a weighing device filter setting and the supply pressure of the substance for weighing. A quantitative dispensing system (1) comprises: a supply device (50) for supplying a substance for weighing; and a weighing device (10) comprising a holding unit (10a) for holding the substance for weighing supplied from the supply device, a load sensor unit (11) for detecting the load from the substance for weighing supplied to the holding unit (10a), and a calculation processing unit (24) for calculating a weighed value for the substance for weighing from the load detection result and controlling the operation of the supply device (50). The calculation processing unit (24) controls the supply device (50) so as to stop the same when the current weighed value becomes greater than or equal to a supply stopping weight value calculated by subtracting a stopping weighed value deviation from a target supply weight value. The calculation of the stopping weighed value deviation takes into consideration the flow rate and supply pressure of the substance for weighing being supplied by the supply device (50) and a filter setting of the weighing device (10).
