FIG. 10 shows this state.

That is, when the push-up ring body 63 pushes up the push-up plate 64, the push-up column 65 moves into the cutout part 23a of the weighing shelf 20a.
The metering device 30 is pushed up from the bottom by penetrating through.

When the weighing device 30 rises, the load cell 39 penetrates the cutout 43a of the box shelf 40a and pushes up the article storage box 50a from the bottom.

As a result, the entire load of the article storage box 50a is applied to the load cell 39, so that the load cell 39 sends out an electrical signal corresponding to this weight value.

Here, if you want to know the number of articles 51a in the article storage box 50a, operate the zero point adjustment knob 37 in advance to calculate the weight value of the empty article storage box 50a (this should be measured in advance). is set on the weighing display 34, and the weight value per article (also measured in advance) is set on the weight per article display 37 by operating the setting knob 36.

In this way, the total weight measured by the load cell 39 is subtracted by the weight value of the article storage box 50a in the electric circuit, and then divided by the weight value per article, resulting in the weight value of the article 51a being subtracted by the electric circuit. The number is displayed on the weighing display 34.

Note that if the setting knob 36 is set to the off position, the weight value of the article storage box 50a is subtracted from the total weight value, and the article 51
The total weight of a is displayed on the weighing display 34.

After the article storage box 50a is weighed, the switch button 6 is pressed.
8 is turned off to make the hydraulic cylinder 61 inactive, the rod 62 is lowered to its original position by the gravity of each load.

At this time, the article storage box 50a and the weighing device 30 are lowered along the slopes of the guide plates 41a and 21a and are respectively placed in the correct positions again.

Next, the weighing device 30 is pulled out from the weighing shelf 20a, placed on the weighing shelf 20b, and pushed all the way along the guide plate 21b to weigh the article storage box 50b in the same manner as described above.

In this embodiment, only two sets of partitioned shelves are shown, but a larger number can be provided.

Further, the shelf supports for supporting each column may be composed of only the columns or only the side plates.

1. As described above, according to the uninvented compartmentalized shelf with a weighing device, it is possible to fit a large number of compartmentalized shelves without using complicated means such as arranging a weighing transmitter on each level of a shelf that is partitioned into several compartments. However, with a simple configuration in which a set of weighing devices is installed and the weighing device is pushed up from below to weigh the load, articles can be taken in and out of the article storage boxes placed on the sorting shelves as appropriate. It becomes possible to easily and accurately measure the current weight and number of articles while the article storage box remains placed, and this has the effect of streamlining the weighing work in warehouses and the like.

Further, it is extremely effective in that it is economical due to the simplification of the configuration.
