Description

TECHNICAL FIELD [Device for regular weight cutting of an object and method thereof]

The present invention relates to quantitative cutting, and more particularly, to an apparatus and method 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.

Moreover, if a large object is to be cut repeatedly by dividing it into small and uniform quantities (eg, sashimi), cutting must be performed quickly and accurately.

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). In addition, repetitive cutting operations (eg cutting sashimi) had to rely entirely on skilled workers.

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.

In addition, recently, there is a case of cutting fish or meat obliquely for visual reasons or cooking convenience rather than cutting at a right angle. In this case, it is even more difficult for the object to be cut obliquely to have a certain quantity.

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 within the scope of the subject. Of course, it includes (fish, 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 correct density, volume and volume profile, and the density is corrected from time to time or as needed. The density is calculated according to [Equation 1].

[Equation 1]

Density = weight / volume

1A is a system for quantitatively cutting an object according to an embodiment of the present invention, a schematic front view of a cutter 360 in a vertical state, and FIG. 2 is a front view of the cutter 360 in FIG. 1A, and FIG. 3 Is a block diagram of the system shown in FIG. 1. 1A to 3, the control unit 300 includes a weight measurement unit 100, a scanner unit 200, a display unit 130, a cutter driving unit 340, a conveyor driving unit 140, and a DB unit ( 320) and the communication unit 320.

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 weight measuring unit 100 is installed at the front end of the first 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 first 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. In particular, the display unit 130 can input the type (eg, mackerel), quantity (eg, 30g), and rotation angle (θ = 30°) of the object 10 through the touchable LED screen.

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 first and second conveyors 120 and 150 at a constant speed, and by linking this with the data of the camera unit 220, an accurate volume profile measurement or cutting position is determined. Used for

In particular, the first conveyor 120 is positioned upstream, and the second conveyor 150 is positioned downstream while being spaced apart by a predetermined interval in connection with the first conveyor 120. Accordingly, the object 10 can be easily moved from the first conveyor 120 to the second conveyor 150. The cutter 360 passes at intervals between the first and second conveyors 120 and 150. In addition, the first conveyor 120 moves at a constant feed rate (v) and has a fixed feed distance (l) between the laser unit 210 and the cutter 360.

The cutter driving unit 340 is interlocked with the control unit 300, receives a control command from the control unit 300, and may feed back the rotation angle position of the cutter 360 to the control unit 300. The cutter driving unit 340 is largely composed of a servo motor 350 and a cutter 360.

As shown in Figure 2, the servomotor 350 is located in the center of the disk 380, it is possible to immediately rotate and stop according to a control command. The servo motor 350 may have an integrated reducer (not shown) and an encoder (not shown).

The cutter 360 cuts the object 10 and has one end connected to the servomotor 350 and the other end being a free end that is free to rotate within the circular guide 370. The weight 355 is installed on the opposite side of the cutter 360 on the servo motor 350 and functions to balance rotation. The speed of the cutter 360 may be expressed as the cutter rotation angular speed (ω).

In the disk 380, a servo motor 350 is installed in the center, a guide 370 is installed in the circumference, and a through hole 375 is formed on one side of the disk 380 to allow the object 10 to pass. The guide 370 is installed to be adjacent to the free end of the cutter 360 to suppress vibration of the cutter 360 during rotation or during cutting, and to enable stable rotation and stopping.

The DB unit 320 of FIG. 3 stores the type of the object 10 and the 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.

The communication unit 330 is connected to the control unit 300 to transmit a control command, operation result, image, DB, etc. of the control unit 300 to an external device (eg, a central server device), and receive data or control commands from the outside. do.

FIG. 1B is a schematic front view of the cutter 360 shown in FIG. 1A inclined by an inclination angle θ. As shown in FIG. 1B, the cutter 360 and the servomotor 350 may be fixed by inclining the vertical line by an inclination angle θ. This inclination angle is the same as the inclination angle θ input through the display 130, and becomes an angle at which the cutter 360 cuts the object 10 obliquely. Means for variably tilting the cutter 360 and the servomotor 350 to fix them (eg, bolts and nuts) are known means, so a detailed description thereof will be omitted.

Vertical cutting motion

Hereinafter, an operation of vertically cutting an object using the system having the above configuration will be described in detail.

4A is a flowchart showing a method of quantitative cutting using the system of FIG. 1A, FIG. 4B is a detailed flowchart of the positioning step S160 in FIG. 4A, and FIG. 5 is an image photographed by the camera unit 220 of the present invention. It is an example of (400).

First, a unit volume corresponding to a pixel pitch of the camera unit 220 is calculated (S100). That is, a cube including a square of an object photographed by one pixel of the CCD of the camera is defined as a unit volume. This varies depending on the resolution of the camera unit 220 (eg, 30 megapixels, 100 megapixels, etc.).

Then, the designated object 10 is input from among the plurality of objects 10, and a quantity is inputted (S110). That is, the operator touches and selects mackerel from the display 130 prior to input, inputs a quantity (eg, 30g), and then inserts the mackerel. The control unit 300 reads the representative density for the selected mackerel (object) from the DB unit 320.

Then, the weight measuring unit 100 measures the weight of the object 10 (S120).

Then, the control unit 300 reads the weight and the representative density of the object 10 designated from the DB unit 320 (S130) to calculate the volume (S140). As a result, the calculated volume value is output.

Then, the camera unit 220 photographs the object 10 to generate an image 400 and a volume profile 510 (S150). 6 is an example of an actual volume curve 500 and a digitized volume profile 510 applied to the present invention. As shown in FIG. 6, the actual volume curve 500 is a smoothly continuous curve, and the volume profile 510 is a set of digitized straight lines formed by stacking unit volumes.

Then, the controller 300 determines the quantitative cutting position 430 on the image 400 based on the unit volume, quantity, weight, calculated volume, and the generated volume profile 510 (S160). 7 is an image in which the object 10 injected into the present invention and a plurality of cutting positions 430 are displayed for quantitatively cutting. When described in detail with reference to FIGS. 4B and 7 are as follows.

First, the number of unit volumes corresponding to the quantity (eg, 30g) is calculated using the representative density (S162). That is, the number of unit volumes required for quantification is calculated as "quantitative/representative density".

Then, the unit volume is added from the first pixel 420 of the object 10 on the image 400 along the volume profile 510 (S164).

Then, a point where the number of calculated unit volumes and the total number of unit volumes are the same is determined as the cutting position 430 (S166). Through this process, the first cutting position 430 is determined from the first pixel 420.

Then, after initializing the summed unit volume, the unit volume is summed again while following the volume profile 510 from the first cutting position 430 (S168).

Then, the second cutting position 430 is determined by repeating step S166 described above. In addition, in this process, steps S166 and S168 are repeated until the last pixel of the object 10 is reached. Then, the result as shown in FIG. 7 can be obtained. 7 is an image in which the object 10 injected into the present invention and a plurality of cutting positions 430 are displayed for quantitatively cutting.

Then, the cutter driving unit 340 rotates the cutter 360 once at the determined quantitative cutting position 430 and cuts it (S170). As shown in Fig. 2, the cutter 360 waits in a horizontal state, and when a cutting command is input from the control unit 300, it makes one rotation with the maximum cutter rotation angular speed (ω), and then waits at the initial position again. Is done. In this process, the cutting process for the first cutting position 430 is completed.

If the cutting position 430 to be cut for repetitive cutting remains as shown in FIG. 7, the cutting step S170 is performed at each cutting position 430. Then, the mass between the respective cutting positions 430 becomes quantitative bodies 400a, 440b, 440c, and 440d each having the same weight. At this time, the interval between each cutting position 430 is different from each other.

Bevel cutting motion

Hereinafter, an operation of obliquely cutting an object using the system having the above configuration will be described in detail. 4C is a flowchart showing a method of quantitative cutting using the system of FIG. 1B, and FIG. 4D is a detailed flowchart of the positioning step S260 in FIG. 4C. In addition, FIG. 8 is an image schematically showing the moment when the cutter 360 of the present invention is inclined by an inclination angle θ, and FIG. 9A illustrates a method of summing the volume from the image shown in FIG. Fig. 9B is an enlarged cross-sectional view of part A in Fig. 9A. However, steps similar to the vertical cutting described above will be briefly described in order to avoid overlapping descriptions.

First, a unit volume corresponding to the pixel pitch of the camera unit 220 is calculated (S200).

Then, the designated object 10 is input from among the plurality of objects 10, and the amount and the inclination angle θ of the cutter 360 are input (S210).

Then, the weight measuring unit 100 measures the weight of the object 10 (S220).

Then, the control unit 300 reads the weight and the representative density of the object 10 designated from the DB unit 320 (S230) to calculate the volume (S240).

Then, the camera unit 220 photographs the object 10 to generate an image 400 and a volume profile 510 (S250).

Then, the control unit 300 is based on the unit volume, the input quantity, the measured weight, the input inclination angle (θ), the calculated volume and the generated volume profile 510 on the image 400, the quantitative cutting position ( 430) is determined (S260). This determination step (S260) will be described in more detail as follows.

First, the number of unit volumes corresponding to quantification is calculated using the representative density (S262).

Next, the sum of the unit volumes from the first pixel 420 of the object 10 on the image 400 to the vertical cut surface 560 along the volume profile 510 to obtain the first volume 530 of FIG. 9A Find Then, the triangular volume 540 under the inclined cutting surface 520 inclined by the inclination angle θ is obtained. The triangular volume 540 uses the coordinates of the unit volume 550 located at the cutting position 430, as shown in FIGS. 9A and 9B. That is, the length of the vertical cut surface 560 can be known from the height of the unit volume 550 located at the cutting position 430, and assuming that it is a right triangle having an inclination angle θ, the area of the triangle can be known. The triangular volume 540 can be obtained by applying the calculated area of the triangle to the volume profile.

Then, the first volume 530 and the triangular volume 540 are summed (S264) (see FIG. 9A).

Then, a point where the number of calculated unit volumes and the total number of unit volumes are the same is determined as the cutting position 430 (S266). Through this process, the first cutting position 430 is determined from the first pixel 420.

Then, after initializing the summed unit volume, the unit volume is summed again while following the volume profile 510 from the first cutting position 430 (S268).

Then, the second cutting position 430 is determined by repeating step S266 described above. Further, in this process, steps S266 and S268 are repeated until the last pixel of the object 10 is reached. Then, the result as shown in FIG. 7 can be obtained. 7 is an image in which the object 10 injected into the present invention and a plurality of cutting positions 430 are displayed for quantitatively cutting.

Then, the cutter driving unit 340 rotates the cutter 360 by one rotation at the determined quantitative cutting position 430 (S270). As shown in FIG. 8, the cutter 360 cuts while maintaining an angle inclined by an inclination angle θ from a perpendicular to the object 10.
