2 is a perspective view showing the installation position of the fear field detection apparatus of the present invention. In the present specification, a description will be given by taking a powder soup packaging apparatus for packaging powder soup with a packaging apparatus in order to explain the fear detecting apparatus for detecting a fear product in a packaged product packaged by the packaging apparatus. As shown in this figure, the powder soup packaging apparatus is similar in structure and operation to the conventional powder soup packaging apparatus of FIG. 1, so that the same reference numerals in the drawings for the same parts are omitted. The fear field detecting apparatus of the present invention is installed in place between the sorter (not shown) located at the rear end of the powder soup packing device 10 and the powder soup packing device 10 so as to drive the motor (not shown) of the sorter (not shown). A fear detector 100 for detecting the fear soup among powdered soups transported to a aligner (not shown) by an alarm), and an alarm generator 190 that notifies the worker acoustically or visually when the fear soup is detected. )

The powdered soup as described above is contained in the rotating measuring cup 13 and then discharged into the wrapping paper, and the packed soup is moved to the fear field detector 100 before being moved to an aligner (not shown) located at the rear of the powdered soup packing device 10. It is determined whether or not it is a horror product. At this time, if the fear product is detected in the packaged product passing through the fear detector 100, the alarm generator 190 is operated to notify the worker that the fear product has occurred.

3 is an exploded perspective view of a fear field detector according to an embodiment of the present invention, and FIG. 4 is a front view of the fear field detector of the present invention.

As shown in Figures 3 and 4, the fear field detector of the present invention is the base 105, the lower plate 110, the guide path for guiding the introduced soup toward the discharge port, the powder soup passing through the lower plate 110 is normal Sensor 115 that detects whether it is a packaged product or a horror product, the sensor base 120 is fixed to the sensor 115, the bottom plate 110 is installed at a predetermined distance away from the sensor 115 in place Mounting top plate 125, fixing bracket 130 for fixing the sensor base 120 in place of the top plate 125, screw 135 for adjusting the gap between the bottom plate 110 and the top plate 125 ), The upper plate 125 is fixed to the front portion, and the vertical movement piece 140 and the vertical movement piece 140, which allow the screw 135 to penetrate, move to the left and right, and move up and down. It is possible to move up and down (14 0) and the lower plate 110 and the upper plate in combination with the column 145, the fixing plate 150 for fixing the up and down moving piece 140 to the screw 135 and the screw 135 are installed to be fastened to And a spacing adjusting nut 155 for adjusting the spacing therebetween.

In the above-described configuration, the lower plate 110 is designed to have a predetermined curvature so that the powder soup to be introduced is in close contact with the upper surface thereof.

As the sensor 115, a high frequency oscillation type proximity sensor, which is a kind of proximity (angle) sensor that detects a distance from a target object in a non-contact state, may be used.

5 is a view for schematically explaining the operation of the high frequency oscillation type proximity sensor applied to the present invention. As shown in this figure, the high frequency oscillation proximity sensor applied to the present invention uses an oscillation coil of a high frequency oscillation oscillation circuit as a detection head. In this detection coil, a high frequency magnetic field of several tens of kHz is generated. Therefore, when there is no magnetic body near the head, there is always oscillation. When the metal nears the head, the oscillation current is generated inside the metal body by induction by receiving the magnetic lines of the oscillation coil. The oscillation decreases or stops to obtain an output. The amount of change in the state is detected by the detection circuit, and the output circuit is operated to detect the metal object. At this time, the detection sensitivity (distance) can be set by adjusting the oscillation amount or the detection amplification degree of the high frequency magnetic field.

In addition, when the packaging material is a nonmagnetic material (plastic, vinyl, wood, paper,…), it has a circuit configuration similar to that of a high frequency oscillation type proximity sensor. Capacitive proximity sensors can be used to detect approaching objects.

The sensing distance of the sensor 115 applied to the fear field detecting apparatus of the present invention is, for example, 4 mm to 6 mm in the lower direction.

On the other hand, in the fear field detection apparatus of the present invention, it is preferable to provide at least two or more such sensors 115. The reason for this is that, when only one sensor 115 is installed, a seam portion passes through the sensor 115. This is because the part is positioned outside the detection distance of the sensor 115 (because the contents are not filled in the joint part), and thus the packaging film is not detected by the sensor 115, and thus it may be incorrectly determined as a fear field. In a preferred embodiment of the present invention, if three sensors 115 are installed to increase the accuracy of the determination and two or more sensors 115 of the three sensors 115 detect the packaging film, it is determined that the package is normal and two or more are detected. If the sensor 115 does not detect the packaging film is configured to determine this as a fear field.

In addition, the interval where the sensor 115 is installed is narrower than the distance of the powder soup joint portion, so when the powder soup joint portion passes through the sensor 115, two or more sensors 115 do not detect the packaging film, and this is regarded as a horror product. In order to prevent erroneous determination, the installation interval between the sensors 115 is made wider than that of the powder soup joint portion. In addition, the sensors 115 may be installed at equal intervals.

The screw 135 and the gap adjusting nut 155 is designed to be screwed, and can adjust the gap between the bottom plate 110 and the top plate 125 by tightening and loosening the gap adjusting nut 155, The space | interval can be designed so that it can adjust to 4 mm-11 mm, for example. In the preferred embodiment of the present invention, the distance between the upper plate 125 and the lower plate 110 is approximately 8 mm, which is adjustable according to the type of product produced by the gap adjusting nut 155.

6 is a cross-sectional view illustrating an example of a fastening state of the vertical moving piece and the pillar in FIG. 3. As shown in this figure, at the upper end of the column 145 to which the vertical movement piece 140 is fastened, a locking projection 145a for preventing the vertical movement piece 140 from flowing down is provided, The moving piece 140 is provided with a fastening jaw 140a that is fastened to the locking protrusion 145a.

7 is an exploded perspective view of a fear field detector according to another embodiment of the present invention. Since the fear field detector according to another embodiment of the present invention is similar in configuration and operation to the fear field detector according to the embodiment of the present invention of FIG. 3, the same reference numerals in the drawings for the same parts will be omitted. As shown in this figure, the fear field detector according to another embodiment of the present invention maintains a gap between the base 105 and the vertical movement piece 140 by using its elasticity on the outside of the screw 135. As a result, a spring 137 spaced apart from the lower plate 110 and the upper plate 125 is installed.

As described above, the soup continuously produced in the powder soup packaging device 10 passes through the inlet of the fear detector 100 and is discharged to the outlet so as to be located at the rear end of the powder soup packaging device 10 (not shown). The soup is moved by a drive motor (not shown) of the aligner (not shown). Thus, the packaged soup is always pulled in the direction of the aligner (not shown). That is, the packaged soup is always pulled in the direction of the outlet, the bottom plate 110 of the fear field detector 100 is designed to have a certain curvature, so that the packaged soup is the bottom plate of the fear field detector 100 ( While passing in close contact with the 110 is passed through the fear field detector (110).

Hereinafter, an operation state of the fear field detecting apparatus of the present invention will be described with reference to the above-described drawings.

8 and 9 are front views showing the operation state of the fear field detector of the present invention, Figure 8 is a view showing a case where the normal packaging product passes, Figure 9 is a diagram showing a case where the fear field product passes. As shown in FIG. 8, when the powdered soup is normally packaged, the soup thickness is about 5 mm, and as shown in FIG. 9, the thickness of the soup having a fear length or insufficient weight is at most 2 mm or less. (This value varies slightly depending on the packaged item, in which case the sensing distance can be adjusted with the gap adjusting nut).

Therefore, when the detection distance of the sensor 115 is adjusted to 5 mm in the lower direction, and the distance between the upper plate 125 and the lower plate 110 is about 8 mm, when the normal soup passes through the detector 100, the upper plate Since the detection distance of the sensor 115 installed in the 125 is 5 mm in the lower direction, when the normal packaged product passes the sensor 115, the wrapping paper is positioned within the detection distance of the sensor 115 so that the three sensors 115 can be detected. At least two or more sensors 115 detect the wrapping paper, and when the horror product passes the sensor 115, the wrapping paper is positioned outside the detection distance of the sensor 115, so that at least two of the three sensors 115 More than one sensor 115 will not detect the wrapper.

10 is a system block diagram for electrically describing the fear field detecting apparatus of the present invention. As shown in this figure, the fear field detecting apparatus 200 according to the present invention includes a packing drive unit 210 for filling and packing powder soup in a metal roll film, and a powder soup packaged in the packing drive unit 210. Whether the powder soup packaged in the motor driving unit 220 and the packing bent portion 210 which is transferred to the aligner (not shown) located at the rear end of the 210 and transported to the aligner (not shown) is a normal packaging soup or a scary soup. In response to a sensor 230 detecting an alarm, an alarm generator 240 that generates an audible or visual alarm, and a fear field based on a detection value input from the sensor 230, driving of the alarm generator 240 is performed. It is provided with a central processing unit 250 to control the alarm.

As shown in FIG. 11, the fear field detection method of the present invention first determines whether the value detected by the sensor S1 in step S10 is 1 (when normal packaging, the packaging film may be detected. If the detection value is 1 and the fear field is not able to detect the packaging film, the detection value is 0). As a result of the determination in step S10, when the detected value in the sensor S1 is 1 (that is, when the packaging film is detected), the process proceeds to step S12 to determine whether the detected value in the sensor S2 is 1. do. As a result of the determination in step S12, when the value detected by the sensor S2 is 1, as shown in Table 1, two or more sensors S1⇒1 and S2⇒ regardless of the detected value of the sensor S3. Since the packaging film is detected in 1), the product passing through the sensor 230 is determined to be a normal packaged product or a seam part, and the process proceeds to step S14 to operate the package driving unit 210 or the motor driving unit 220 normally.

If it is determined in step S12 that the detected value of the sensor S2 is not 1, the process proceeds to step S16 to determine whether the detected value of the sensor S3 is 1. As a result of the determination in step S16, when the detected value of the sensor S3 is 1 (S1 ⇒ 1, S2 ⇒ 0, and S3 ⇒ 1), the product passing through the sensor 230 is determined as a joint portion of the soup (S18). If the packaging bent portion 210 or the motor driver 220 is operated normally, and the detected value of the sensor S3 is not 1 (S1⇒1, S2⇒0, S3⇒0), the sensor 230 The product passing by) is determined as a fear product and proceeds to step S20 to stop the operation of the packaging driving unit 210 or to drive the alarm generator 240 to inform the worker that the fear product has occurred.

If it is determined in step S10 that the detected value of the sensor S1 is not 1, the process proceeds to step S22 to determine whether the detected value of the sensor S2 is 1. As a result of the determination in step S22, when the detected value of the sensor S2 is 1, the process proceeds to step S24 to determine whether the detected value of the sensor S3 is 1. As a result of the determination in step S24, when the detected value of the sensor S3 is 1 (S1 ⇒ 0, S2 ⇒ 1, S3 ⇒ 1), the product passing through the sensor 230 is determined as a joint portion of the soup (S26). In the case where the pavement drive unit 210 or the motor drive unit 220 is normally operated and the detected value of the sensor S3 is not 1 (S1⇒0, S2⇒1, S3⇒0), the sensor 230 Determining the product passing under the weight or the fear product to proceed to step (S28) to stop the operation of the packaging drive unit 210 or to drive the alarm generator 240 to inform the worker that the fear product has occurred. .

As a result of the determination in step S22, when the detected value of the sensor S2 is not 1 (S1 ⇒ 0, S2 ⇒ 0), as shown in Table 1, two, regardless of the detected value of the sensor S3, Since the packaging film was not detected by the above sensors S1 ⇒ 0 and S2 ⇒ 0, the product passing through the sensor 230 is judged as a fear, and the process proceeds to step S30 to stop the operation of the packaging driving unit 210. The alarm generator 240 is driven to inform the worker that the horror product has occurred.
