Title: Counter balance and counting method
Inventor: SUZUKI SHOJI
IPC: G01G19/42
Filed: 1993-05-11
Abstract: PURPOSE:To count accurately and quickly even when the weigh fluctuates significantly and the number of articles to be packed is high by subtracting a previous weight value from a current weight value, dividing the difference by a reference weight value and then adding the quotient. CONSTITUTION:Articles fewer than an allowable count (for suppressing the count error below an allowable level) which is fewer than a target count are loaded sequentially on a mount 1 while dividing into a plurality of times and a metric section 2 measures the weight of the articles every time when they are loaded. An operating section 4 subtracts a previous weight value from a current weight value and divides the difference by a reference weight while furthermore counts the articles loaded on the mount 1 every time when the articles are measured. The counts are then added to determine a total number. In other words, the count error caused by the total weight of target number of articles is divided by the number of measuring times and suppressed. This method limits the count error to a small level occurring when the measurement is conducted individually thus suppressing the count error as compared with the case where a target number of articles are counted simultaneously.

A second chamber 72 communicates with an air chamber A by a second communicating pipe 721 via a fixed metering part 722. Due to this arrangement, since an inner pressure in the second chamber 72 is equal to an inner pressure P3 within the air chamber A, a decreased pressure caused by the fixed metering part 22 (a pressure losing means) is applied. The first chamber 71 communicates with an outlet port of a nozzle 31 through a first communication pipe 711. Due to this fact, an inner pressure within the first chamber 71 is equal to an inner pressure P5 at the outlet port of the nozzle 31. The first diaphragm 61 has the same pressure receiving area as that of the third diaphragm 63. The operating rod 8 is displaced until these loads are balanced to each other, the operating rod is converged at a position where its opposing force is balanced with the former and then an amount of raw gas is supplied.

Abstract: PURPOSE:To enable the automation of the replacement of gas in a coiled pipe and the improvement in working efficiency and working environment by providing vacuum purging chambers adjacently to the inlet and outlet of a continuous annealing furnace and carrying the coiled pipe into the chamber, then sealing the prescribed gas therein. CONSTITUTION:The vacuum purging chamber 4 is provided adjacently to the inlet (furnace heating chamber 2 and furnace front chamber 1) of the continuous annealing furnace.
