Density calculating and calibration system for a regular weight cutting of an object and positioning method of cutting position

The present invention relates to density measurement, and more particularly, to a density calculation and calibration system for quantitative cutting of an object.

In general, when mass processing and packaging of meat (beef, pork, chicken, duck, etc.), aquatic products (fish, shellfish, seaweed, etc.), agricultural products, forest products, etc., uniform weight (hereinafter referred to as "quantitative") ) Packaging is done in units. And the packaged products are distributed nationwide through marts, traditional markets, home shopping, and internet order delivery. Therefore, if one object (meat, aquatic products, agricultural products, etc.) has different weights and is larger than the quantity required for processing, it is necessary to cut it in quantity during processing.

However, in the past, workers cut fish based on their own experience or cut fish in a standardized manner. And the price was calculated by measuring the weight of the cut fish slices in units of 1g (eg, 243g fish slices, 4,520 won).

Therefore, it was very difficult to cut the fish continuously in units of quantification (eg 300g). For example, for larger cuts (e.g. 310g), the quantity can be adjusted manually, but for smaller cuts (e.g. 290g), it has to be discarded or used for other purposes. In particular, the fish (e.g. mackerel) that is stocked every day for cutting work differs by season (e.g., summer, winter), varies by country of origin (e.g., domestic, imported), and depends on the type of farming (e.g., wild, aquaculture) Since it is different and depends on the condition (e.g., biological, semi-dried, frozen), quantitative cutting in large quantities was an essential and technically difficult task.

Example of Configuration

Hereinafter, a configuration of a preferred embodiment will be described in detail with reference to the accompanying drawings. In the embodiments of the present invention, the subject is limited to fish and illustrated and described. However, this is for the purpose of helping those skilled in the art understand and includes meat (beef, pork, chicken, duck, etc.), aquatic products. Of course, it includes (fish, shellfish, seaweed, etc.), agricultural products, and forest products.

First, when a fish is to be cut quantitatively, the density information of the fish is an important factor. Therefore, the quantitative cutting position is determined based on the calculation of the correct density and the measurement of the volume, and the density is corrected from time to time or as necessary. The density is calculated according to [Equation 1].

[Equation 1]

Density = weight / volume

1 is a schematic front view of a density calculation system for quantitatively cutting an object according to an embodiment of the present invention, and FIG. 2 is a block diagram of the system shown in FIG. 1. 1 and 2, the control unit 300 includes a weight measurement unit 100, a scanner unit 200, a display unit 130, a conveyor driving unit 140, a DB unit 320, and a communication unit 330. ).

The weight measurement unit 100 measures the weight when the object 10 is raised, and the measured weight data is transmitted to the control unit 300. The weighing unit 100 is installed at the front end of the conveyor 120 to measure the weight in advance. To this end, the weight measurement unit 100 may be an electronic scale or a digital scale.

The scanner unit 200 scans the object 10 being transferred on the conveyor 120 to measure the volume or take an image. The scanner unit 200 may be a 3D scanner, and more specifically, it is divided into a camera unit 220 and a laser unit 210.

The laser unit 210 irradiates the line laser 215 toward the conveyor 120.

The camera 220 is a digital camera capable of capturing an image (still image) or a moving image of the object 10 to which the laser 215 is irradiated. The camera 220 may be implemented as a single device or a stereo camera. A separate LED lighting (not shown) is provided near the camera 220 for such photographing. Then, the image or video of the camera 220 is transmitted to the controller 300.

The display unit 130 is a touchable LED screen that displays control operations, input/output, etc. of the entire system or receives a menu selection from an operator.

The conveyor driving unit 140 is a means for transferring the object 10. The conveyor driving unit 140 is connected to the control unit 300 to operate the conveyor 120 at a constant speed, and is used for accurate volume measurement or cutting position determination in connection with the data of the camera unit 220.

The DB unit 320 stores the type of the object 10 and a representative density corresponding to each object 10 in association with each other. The DB unit 320 is a database table, and may store or search for density data and output it. To this end, the DB unit 320 may be implemented as a memory, a hard disk, or an SSD.

Calculation of representative density

Hereinafter, a representative density operation operation of a preferred embodiment will be described in detail with reference to the accompanying drawings. 3 is a flowchart showing a method of calculating the representative density using the system of FIG. 1, and FIG. 5 is an example of an image 400 captured by the camera unit 220 of the present invention. As shown in FIGS. 3 and 5, first, the operator inputs the first sample of the object 10 (S100). For example, one (first sample) of a plurality of mackerel (object) is prepared and introduced into the system.

Then, the weight measuring unit 100 measures the weight of the first sample of the object 10 (S110). The measured weight data is transmitted to the control unit 300 and stored.

Then, with respect to the object 10 being transferred by the conveyor (transfer means), the scanner unit 200 measures the volume (S120). In volume measurement, when the line laser 215 is directly irradiated from the laser unit 210 and the object 10 passes therebetween, the camera unit 220 photographs the volume to measure the volume.

Then, the control unit 300 calculates the density from [Equation 1] based on the received weight data and volume data (S130).

Then, the calculated density is temporarily stored in the control unit 300 (S140).

Then, steps S110 to S140 are repeatedly performed for a plurality of samples (eg, other mackerel prepared) of the object 10 to calculate and store a plurality of densities (S150).

Then, when all samples are injected, the control unit 300 statistically processes the stored plurality of densities and stores them in the DB unit 320 as the representative density of the object 10 (S160). That is, the controller 300 calculates an average value from 10 density data measured for 10 mackerel, and stores it in the DB unit 320 as a representative density of the object 10. That is, the object (mackerel): has the same shape as the average density (1.2 g/cm ³ ).

This process is repeated for other objects (eg, saury) to continuously store representative densities for several objects.

Representative density calibration

4 is a flowchart illustrating a method of calibrating a representative density using the system of FIG. 1. As described above, the representative density of the object 10 is calculated and stored, but if it is continuously used as a fixed value, it does not match the state of the object 10 and is thus incorrectly cut. Therefore, the following density calibration process is required at regular intervals or whenever necessary.

First, a designated object among the plurality of objects 10 is injected (S200).

Then, the weight measuring unit 100 measures the weight of the object 10 (S210).

Then, for the object 10 being transported by the conveyor 120, the scanner unit 200 measures the volume (S220).

Then, the control unit 300 calculates the density based on the weight and volume (S230).

Then, the control unit 300 reads the representative density stored in the DB unit 320 and compares it with the calculated density. As a result of the comparison, it is determined whether the error is within the allowable range (S240).

If it is within the allowable range, the representative density is not corrected. This is interpreted to mean that the representative density is accurate enough to be used. However, if it is out of the allowable range, the representative density is corrected and stored in the DB unit 320 (S250). That is, since it means that the representative density of the DB unit 320 does not match the density of the currently input object, the representative density is corrected to be more accurate. The corrected representative density may be transmitted to the outside through the communication unit 330 and managed integrally at the center or may be utilized in other cutters.
5 is an example of an image 400 captured by the camera unit 220 of the present invention.
When the laser 215 is irradiated while transporting the object 10 in the transport direction 410, the right end of the object 10 becomes the first pixel 420. According to the present invention, the cutting position 430 of the object 10 may be determined in order to provide the quantitative body 440 by calculating the density.
