In general, a metering injection device is used to inject liquid contents into a packaging container.

The metering injection device is a device for automatically injecting a predetermined amount into a packaging container. Liquid or gel contents such as cosmetics, medicines, and foods are injected into packaging containers having various sizes and shapes using such a metered injection device.

Each packaging container must be injected in an appropriate amount, that is, a fixed amount. Therefore, a device for confirming whether the amount injected into the packaging container is quantitative is required for this purpose.

Republic of Korea Utility Model Registration No. 20-0362077 discloses a quantitative detection device for packaged beverages.

The quantitative detection device has a configuration for detecting the level of the contents contained in the pack by a level sensor and confirming the quantitative amount. Since the quantitative detection device using such a level sensor detects the level of the contents, there is a problem in that the weight of the contents cannot be measured.

In addition, the quantitative detection device can only detect the quantity of beverages with very low viscosity, and is difficult to apply to a technology for injecting and packaging gel-like contents with high viscosity, such as cosmetics.

The above-described metering injection confirmation device of the present invention can accurately detect whether not only liquid but also high-viscosity gel-like contents have been injected in a fixed amount.

Hereinafter, a quantitative injection confirmation method using the quantitative injection confirmation device of the present invention will be described.

Referring to FIGS. 1 and 2, the method for confirming quantitative injection of the present invention includes the first measuring step of measuring the weight of an empty container 1 with a first electronic scale 3, and the contents injected into the container 1. After the second measuring step of measuring the weight of the container 1 with the second electronic scale 5, the first weight value measured by the first electronic scale 3 and the second electronic scale measured by the second electronic scale 5 2Injection amount calculation step that calculates the injection amount of the contents by the difference in weight value, and constant injection discrimination step that compares the injection amount calculated in the injection amount calculation step with the set tolerance to determine whether or not the constant injection is performed, and the constant injection discrimination step determines It includes a display step of visually displaying whether or not the dose has been injected. Let's look at it step by step.

1. 1st measurement step

In the first measurement step, the weight of the empty container 1 into which the contents are to be injected is measured. The empty container 1 is placed on the first electronic scale 3 to measure the weight of the empty container 1, that is, the first weight value.

The empty container 1 whose weight is measured on the first electronic balance 3 is injected with a certain amount of contents through a conventional injection device.

2. Second measurement step

In the second measuring step, the weight and second weight value of the container 1 into which the contents are injected are measured. The container 1 into which the contents are injected is placed on the second electronic scale 5 to measure the second weight value.

3. Injection amount calculation step

The injection amount of the content is calculated by the difference between the first weight value measured by the first electronic scale 3 and the second weight value measured by the second electronic scale 5.

The first weight value measured by the first electronic scale 3 and the second weight value measured by the second electronic scale 5 are input to the control unit 10 . The control unit 10 calculates the injection amount of the content based on the difference between the first weight value measured on the first electronic scale 3 and the second weight value measured on the second electronic scale. The injection amount is calculated by the following formula.

Injection amount = 2nd weight value - 1st weight value

4. Quantitative injection determination step

In the step of calculating the amount of injection, the calculated amount of injection is compared with the set tolerance to determine whether or not to inject a fixed amount. Tolerances are preset. As an example, the tolerance may be set to ±3% of the quantification.

The control unit 10 compares the injection amount calculated in the injection amount calculation step with the set tolerance to determine whether the fixed amount is injected.

If the calculated injection amount is within the allowable error range, the control unit 10 determines it as a fixed injection, and if the calculated injection amount is out of the allowable error range, the controller 10 determines it to be defective injection.

5. Display stage

In the display step, whether or not the amount of injection is visually displayed through the display unit 11.

When it is determined that the amount of injection is determined, the control unit 10 turns on a first lamp generating light of a first color. In addition, if it is determined that the injection is defective, a second lamp generating a second color light is turned on.

In the case of metered injection, after the first lamp is turned on, the control unit 10 determines the first weight value measured by the first electronic scale 3, the second weight value measured by the second electronic scale 5, the injection amount, and the count value stored in memory. Then, the process of injecting the contents into a new container begins again.

On the other hand, in the case of defective injection, an injection amount adjustment step of adjusting the injection amount of the container 1 into which the contents are injected may be further performed.

When the second lamp is turned on due to defective injection, the manager collects the container 1 into which the contents have been injected and injects a certain amount of contents. The container 1 to which the contents are further injected is weighed again on the second electronic scale 5. At this time, the measured weight value may be referred to as an adjusted weight value.

The control unit 10 recalculates the injection amount of the content by the difference between the adjusted weight value and the first weight value, and compares the calculated injection amount with a set tolerance to determine whether to inject a fixed amount again.

After determining whether or not to inject the quantity, the above-described displaying step is performed. In case of defective injection after the display step, the injection amount adjustment step is performed again. The above injection amount adjustment step is repeated until the injection amount of the container is fixed.

In the above, the present invention has been described with reference to one embodiment, but this is only exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom. Therefore, the true protection scope of the present invention should be defined only by the appended claims.
