Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application Meter The present invention relates to a method for quantitatively filling a shape-retaining container such as a plastic cup with contents consisting of a liquid and a solid substance.

Conventional technology Conventionally, liquid or viscous foods containing solids (e.g., meat with pulp, potatoes, carrot-type curry roux, etc.) have been stored in shape-retaining containers such as plastic cups, paper cups, and metal cans. ) are in circulation.

In such products, there is no variation in the amount of solids,
Furthermore, it is required that the total amount be filled in a fixed amount.

Conventionally, there are two known methods for filling a fixed amount of the contents as described above: a method in which the liquid and solids are mixed in advance and then filled in a fixed amount at once, and a method in which the liquid and solids are filled separately in a fixed amount. There is.

Problems to be Solved by the Invention The method of pre-mixing liquid and solid matter and then filling the mixture uniformly allows for quantitative filling in total, but there is a problem in that the amount of solid matter etc. varies widely. On the other hand, the method of filling the liquid and solids separately reduces the variation in M slip etc. of the solids, but there is a problem that the total amount varies due to the variation in weight (or volume) of each solid. be.

For example, when filling a molded container with jelly containing one piece of fruit pulp, if the weight variation of each piece of fruit pulp is 3 g, no matter how accurate the liquid filling is, there will be a total variation of 3 g.

Therefore, conventionally, it has been considered difficult to fill the fixing device with uniformity in both the solid matter and the total amount. Therefore, when filling solids and liquids separately in fixed amounts, the actual situation is to predict the dispersion of solids in advance and fill a slightly larger amount of liquid than the specified amount. As a result, in a filling line that fills a large number of products, the total amount of excess material (the total amount to be filled) becomes large, which causes waste and increases costs.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to
It is an object of the present invention to provide a method for quantitatively filling a shape-retaining container with reduced variations in both solids and total amount.

Means for Solving the Problems The present invention includes a primary filling step in which a predetermined amount of liquid content and a predetermined amount of solid matter are separately filled, and a second step in which the amount of content in the filled container is detected and immediately detected. The content consisting of liquid and solids is filled into the shape-retaining container through a secondary filling process in which the liquid content is compared with the quantitative set value and if there is a shortage, the content liquid is corrected and filled by the amount corresponding to the shortage amount. Automatic quantitative filling.

Since the solids are separately filled in fixed quantities in the primary filling process, variations in the solids can be avoided. Then, in the next step, by detecting the amount of the contents in the container and correcting and filling the insufficient amount with liquid, it is possible to eliminate variations in the total amount. Embodiments Hereinafter, embodiments of the present invention will be described in detail.

A case will be described in which a container 1 as shown in FIG. 1 is filled with jelly containing one piece of seven elephant meat 2 as a solid substance.

First, in the second filling step, one fruit pulp 1 and a predetermined amount of jelly liquid 3 are filled into a container being conveyed on a conveyor using a well-known method. The company that produces the jelly liquid 3 that is filled in the primary filling line is
The amount should be slightly less than the specified amount that will be finally filled.

- The container filled with fruit pulp 1 and a predetermined amount of jelly liquid 3 in the next filling process is further conveyed by a conveyor, and the liquid level height is detected in the secondary filling process.

The drawings show an example in which an air sensor is used as the liquid level detection lid.

In the figure, 5 is a stop valve, 6 is a filter,
7 is a precision regulator that adjusts air pressure, 8 is a pressure gauge, 9 is a micro filter, 10.11 is a throttle valve, 12
is a nozzle sensor, an ultra-low pressure switch that converts 13#i air pressure into an electrical signal. - Next, when the filled container reaches the lower part of the nozzle sensor, it stops, and air, which is controlled at a predetermined pressure and amount by a precision regulator and throttle valve, is initially filled from the nozzle sensor 12 and blown out onto the liquid surface. At this time, the pressure that the nozzle sensor receives differs depending on the distance between the nozzle and the liquid level, so by detecting the pressure, the liquid level height can be detected. The pressure detected by the nozzle sensor 12 is converted into an electrical signal by the ultra-low pressure switch 13 and transmitted to a secondary filling control device (not shown). The control device allows the liquid level height to be set arbitrarily, and a prescribed liquid level height is set in advance.

The control section continuously compares the set liquid level height with the current liquid level measured by the nozzle sensor, and the comparison signal is used for liquid correction filling (not shown). Open the magnetic valve and fill with liquid 4 until the measured value and set value match.

In the case of the above embodiment, the liquid level height is detected using only one nozzle sensor, but there is a risk that the liquid level will fluctuate during correction filling, causing a measurement error. In order to solve this problem, more precise measurements can be made by setting multiple nozzle sensors at different positions, detecting at multiple points simultaneously, and using the uniformity of the sensors as a measurement field.

In addition, in the above example, the liquid for the primary filling is filled in an amount slightly less than the standard liquid, but the specified liquid amount is filled in the primary filling, and solids are removed in the secondary filling. If the amount is less than the specified amount and the weight is less than the specified amount, the liquid may be corrected and filled.Also, in the above embodiment, an air nozzle sensor is used as the liquid level detection means, but the liquid level detection means is an air nozzle sensor. Various detection means can be applied as long as it is a non-contact detection means that does not make mechanical contact with the liquid surface, such as a detection means that detects the liquid level height based on the reflection angle or the like.

Furthermore, it is also possible to measure the weight and perform correction filling based on the weight, without depending on the liquid level.

In that case, the container that has been primarily filled and transported by a conveyor is placed on a weight detector @ loess installed below the secondary filling device, and its weight is measured.

The measured values are transmitted to the control device and processed in the same manner as described above.

Effects As has been explained in detail above, it is clear that according to the method for quantitatively filling contents consisting of liquid and solids into a shape-retaining container according to the present invention, variations in both solids and IT can be reduced. Since it can be filled in fixed quantities, it makes a great contribution to quality control.

Further, unlike the conventional method, there is no need to fill an extra large number of ports with liquid in order to compensate for a shortage in the total filling amount due to variations in solids, so filling can be performed efficiently and is economical. Furthermore, the present invention has various special effects such as being able to be implemented with a simple device.
