Embodiment 1

[0056] In the figure, 10 is the combination metering device of embodiment 1 of the present invention, and this combination metering device 10 has: outer casing 11; Be arranged on the top of outer casing 11 and store the top of the corn flakes (measured object) of given amount The hopper 12; the distributing part 13 provided at the outlet of the upper hopper 12 and distributing the corn flakes in a certain amount per unit time; the lower hopper 14 arranged directly below the outlet of the upper hopper 12 and receiving the corn flakes discharged by the distributing part 13 Totally 5 pipe feeders 15 arranged substantially horizontally at the lower end of the lower hopper 14; respectively arranged directly below the outlet of each pipe feeder 15 and receiving the corn flakes discharged from each pipe feeder 15 and Two sets of metering devices 16A and three metering devices 16B for a small amount of metering; the control unit 17 has a selection circuit 17a (Fig. The total weight of...

Embodiment 2

[0089] Next, a method of performing combination counting of pharmaceutical tablets (objects to be weighed) using a combination counting device 10A having the same structure as the combination metering device 10 of Example 1 will be described with reference to FIGS. 1 to 5 . Here, a method of filling 100 tablets (100 g) per bag is taken as an example, where each tablet is 1 g.

[0090] Into the weighing hopper 55 of each large-volume input meter 16A, tablets of the following weight (90 g) are dropped into the maximum input weight (90.9 g) including the tablet input weight deviation (±1%) of the weight (90 g) , which is smaller than the target weight value (100g) corresponding to the target number value (100) of the combination count. In addition, into the weighing hopper 55 of each weighing device 16B for a small amount of feeding, tablets of the following weight (5 g), which is lighter than the weight of the tablet feeding in the weighing device 16A for a large amount of feedi...

Abstract

A combined weighing apparatus allowing an increase in the accuracy of combined weighing or combined counting for weighed materials. Since one unit of weighing device for large charge is always selected in a selection process, a target weight value is substantially reduced. Accordingly, the reduced target weight is uniformly divided by two units of weighing devices for small charge. As a result, the accuracy of the combined weighing of cornflakes or the combined counting of tablets can be increased.

Description

technical field [0001] The present invention relates to a combination weighing technique, and specifically relates to a combination weighing technique in which a combination of scales is selected so that the total weight of objects to be weighed to be supplied to a plurality of scales becomes an optimum weight, and these scales are combined The objects to be measured are collected. Background technique [0002] For example, mixed foods (objects to be weighed) mixed with dry foods such as seaweed, sesame, dried fish, and dried vegetables are sold in plastic pouches. [0003] Conventionally, as a mixed food weighing device equipped in a mixed food bagging system, for example, a combination weighing device capable of high-speed and accurate mixed food measurement as described in Patent Document 1 is known. The device selects a combination of scales so that the sum of the weights of the mixed food supplied to a plurality of scales is an optimum weight, and collects the objects ...
