難しい。<Problem to be Solved by the Invention> In this case, conventionally, as shown in FIG. 3, weighing machines 67 with different large and small maximum weighing values or weighing precisions are installed separately and used selectively. There is. In this case, the containers 8.9 are manually carried into and out of the weighing machines 6 and 7. Of course, the container 8.9 may be conveyed to the weighing machine 6.7 via a conveyor or the like, or the container 8.9 may be transported to the weighing machine 6.7 via a conveyor or the like.
It is also possible to automate the transportation of the containers 8 and 9, such as transporting them from the weighing machine 6 to the destination.
It is difficult to place the item in the center of 7 or on the conveyor.

Next, the lifting device is driven to move the support means to the lowered position. By lowering the support means, the state in which the object to be weighed is placed and supported by the support means is released, and the object to be weighed shifts to a state in which it is placed and supported by a weighing platform corresponding to the size of the object to be weighed. . Therefore, the load of the object to be weighed is applied to the weighing machine supporting the weighing platform.

で移動する。かかる支持手段の上昇によって、支持台に
よる容器の載置支持状態が解除され、容器は再び支持手
段によって載置支持された状態に移行する。When the weighed value reaches a predetermined value and the loading of the object to be weighed is stopped, the lifting device is driven to move the support means to the above-mentioned raised position. By raising the support means, the state in which the container is placed and supported by the support table is released, and the container shifts to a state in which it is placed and supported by the support means again.

重量を差し引いて重量を求めるようにする。If you do not put the object to be weighed into the container during weighing, but simply measure the object that has been placed in the container in advance, or directly measure the object to be weighed, such as a solid, without using a container, the Weighing is performed without placing the object to be weighed on the
The weight is determined by measuring the tare weight applied to a weighing machine such as a weighing platform and subtracting the tare weight.
