Abstract

PURPOSE:To enable the realization of an automatic system of weighing accurately even powder or a substance having viscosity, by discontinuing the use of a weighing saucer or the like and by weighing automatically the substance to be weighed, while feeding same directly into a vessel from a feeder. CONSTITUTION:A discharge port of a vibration-type feeder 9 is formed so that it can be put inside a vessel 11, and a substance 10 to be weighed is fed out little by little from a supply tank 8 by means of the feeder 9. According to this constitution, the substance 10 to be weighed is fed in without overflowing from the vessel 11, and a weighing device 12 positioned below the vessel 11 can weigh automatically the weight of the substance 10 together with the weight of the vessel 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel automatic metering system. More specifically, the present invention relates to a weighing method in which an object to be weighed sent from a vibrating feeder is automatically weighed while being placed directly into a container.

A conventional automatic weighing system will be explained using FIG.

The object to be weighed 3 is fed out little by little from a supply tank 1 using a vibrating feeder 2, and weighed while being put into a tray 5 by a weighing receiver attached to a weighing device 4. When the weighing is completed, the feeding device @2 is stopped, and the weighing object 3 is automatically transferred from the weighing tray 5 to the container 6 in which it will be finally placed.

However, in this method, when transferring powder or a viscous object to be weighed from the pan 5 to the container 6, the weighing receiver is used to prevent part of the object 3 from adhering to the pan 5. Therefore, there is a problem that the contents cannot be transferred to the container 6 according to the measured weight. In reality, the object to be measured 3
It is also difficult to directly transfer the weighing tray from the pan 5 to the container 6, and during this time it is necessary to guide it to the mouth of the container with a funnel-shaped tube 7, and the object to be weighed 3 may also adhere there. Due to storage, the situation was such that only a much smaller weight than the measured weight could be transferred. Furthermore, since this amount of adhesion is not constant, it is difficult to correct it automatically.

Therefore, the weighing of powders and viscous objects to be weighed has had to be done manually. Specifically, the method was to place a container on a scale, and while looking at the scale, directly add the object to be measured using a spoon-like object.

In the present invention, the above-mentioned measuring tray or the like is eliminated, and by automatically measuring the object while feeding the object directly from the feeding device into the container, the amount of the object to be measured is at an intermediate stage. As a result of intensive research into solving the problem of adhesion to dishes, etc., we were able to achieve this using the method shown below.

An example is shown in FIG. In this figure, the steps up to the part where the object to be weighed 10 is sent out little by little from the supply tank 8 using the vibrating feed device 9 are the same as in the conventional method, but in this method, the shape of the vibrating feed device 9 is Adding some ingenuity,
This discharge port is connected to the container 11 in which the object to be weighed 10 is finally placed.
By forming the container so that it fits inside the container, the object to be weighed 10 can be fed into the container without spilling. At this time, the weighing device 12 is located below the container 11, and the weight to be measured is 100 fed into the container 11 by the feeding device 9 is automatically weighed together with the weight of the container 11. Here, what we actually want to find is the weight of only the object placed in container 811, but the weight of container 11 should be weighed and memorized before placing the object to be measured in it. It is also possible to find only the weight of the object to be weighed by subtracting the li amount of the container from the total weight of the object and the container, and it is also possible to do this automatically. be.

Using the direct automatic weighing method of the present invention, it is now possible to accurately and automatically weigh powders and viscous objects, which were considered extremely difficult in the past, and they can also be weighed using the same measuring instrument. This increases the number of types of objects to be weighed, making the device extremely versatile. In addition, since there is no need for a plate or a funnel-shaped tube to measure the dose at the intermediate stage, there are two additional effects. One is that manufacturing costs can be reduced by reducing the number of parts in the automatic weighing device manufacturing process, and the other is the effect of using automatic weighing devices, which is useful when changing the type of object to be weighed. This means that cleaning work is no longer necessary, increasing work efficiency.
