Description

The present invention relates to a combination weighing machine for weighing vegetables, foods, etc., and a method of using the combination weighing machine and the combination weighing machine capable of efficient weighing with a simple configuration.

When selling vegetables, foods, etc., it is necessary to weigh the contents so that the amount does not fall below the specified amount. This is because if the amount is less than the displayed amount, the buyer will be deceived. However, it is uneconomical to put a large amount of products far from the prescribed amount, which leads to cost increase.

Such a contradiction is remarkable in agricultural products whose size, shape and weight are not uniform. For example, when selling vegetables, they are rarely sold in units of one, one, or one share, and the mainstream is to pack them in bags in a certain amount and sell them in a certain amount, and do not fall below the specified amount. Moreover, it is required to weigh the minimum combination.

In mass-produced food factories and large-scale shipping centers, the target products are automatically transported, placed on a combination weighing machine, weighed the minimum combination that exceeds the specified weight, and selectively this with a hopper or the like. In many cases, we have introduced and used an automatic machine that discharges food to the product and packs it in bags. However, individual farmers and small-scale shipping associations cannot afford to introduce large-scale and expensive combination weighing machines, and the actual situation is that weighing is performed manually.

There is a demand for a method of using a weighing machine having a plurality of measuring parts and a measuring machine having a plurality of measuring parts, which enables efficient weighing with a simple configuration, but usually a single scale is used. Many and efficient products have not been put into practical use. In particular, it is very effective if it can be used in combination with a transfer device as an efficient method of using a weighing machine having a plurality of weighing parts, but the combined measuring machine and the weighing object can be transported with a simple configuration. A device in which the mechanisms that operate in synchronization and how to use it have not been realized.
