  • Weight Measurement For Supplying Or Discharging Of Specified Amounts Of Material (AREA)

Abstract

PURPOSE:To simplify a constitution and to improve operability by switching automatically a measuring machine to be supplied additionally in accordance with the sum of the total weight of measuring machines participated in a combination measurement and the comparison results of a certain proportion of an established weight. CONSTITUTION:In case of the most suitable combination being unobtainable the sum S0 of the total weight of a measuring machine 1 joined in the combination measurement is calculated and the comparison of this sum S0 with the prescribed proportion of the established weight Wa of a weight establishing part 6, for instance, X0>WaX4/3 is decided. If this condition is satisfied, three units of a measuring machine 1 having a smaller weight value are selected in order from the lightest one, for instance, and additional supply of goods is performed to these. On the other hand in case the conditions are not satisfied the accuracy of the combination measurement is improved with the additional supply of goods to all of the measuring machines 1 not exceeding a certain weight and also the arithmetic processing is carried out quickly.

(Problems with the Prior Art) In the conventional combination weighing device, when only the optimum combination can be obtained, articles are additionally supplied to a predetermined weighing machine in order to improve the accuracy of the combination weighing. This additional supply may be performed on all weighing machines whose weighing data is below a certain weight, or may be performed on a predetermined number of weighing machines with small weight values, and the operator can switch the additional supply mode empirically. This was done by operating the swift. For this reason, an additional supply mode selector switch is required, which complicates the configuration of the combination weighing device.
It also had the disadvantage of being complicated to operate.

(Summary of the Invention) The combination λ' weighing device of the present invention includes a plurality of weighing machines each having a weight detection section that detects the weight value of an article put into each weighing hopper, and weighing data obtained from the weight detection sections inputted. The calculation control unit calculates the combination of the four quantity data according to a predetermined combination pattern, and calculates the optimum combination obtained. If the optimal combination cannot be obtained for items that are discharged from the applicable weighing machine, the total weight sum of the weighing machine heads that participated in the combined weighing is calculated, and the total weight sum is compared with a certain percentage of the set weight value. The weighing machine has a control means for switching between supplying additional articles to a predetermined number of weighing machines that are light in weight, or supplying articles additionally to all weighing machines that weigh less than a certain weight.

Next, set 1 to the pattern counter in step P1.
4) Sequentially read out the combination addition values for each combination pattern from the memory one by one and calculate (combination addition value - set weight) = A (step P15), and when the condition A≧0 is satisfied, the memory Set the positive flag to ■Step P1
6) Compare A with the contents of the error memory set at step pH (step P17). Error memory 1〉A
When the condition is satisfied, the below-upper limit flag is set to 0, and the contents of the error memory are updated to the value of A and stored. Also, update the contents of the pattern memory with the pattern counter value and store it (step 21, P2O). After that, continue the processing of 7temps P15 to P19 until the pattern counter ends while incrementing the pattern counter by 1 ( Step P20.P2+).

When it is confirmed that the city flag is ■, it is determined whether the -1- limit or less flag is ■ (step P23), that is, if the combined added value is less than the -F limit weight value, the process goes to step P24, and all M1
If the combined addition value is less than the upper limit weight value (defective combination occurs), the process of step P50 is executed.
