Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1, the packaging defect detection apparatus A of the pouch-packaged product 100 according to the present invention includes a transfer unit 10, a pressing unit 20, a diffusion unit 30, a dust collecting unit 40, And a lid portion 50.

The transfer unit 10 transfers the pouch packaged product 100 in one direction.

The transfer unit 10 includes a motor 11; And a belt (12) running continuously by driving the motor (11).

Accordingly, the pouch packaged product 100 is automatically transported in one direction by placing the pouch packaged product 100 packaged on the upper surface of the belt 12 being driven.

The transfer unit 10 is arranged to be connected to the end of the pouch-packed product production line 200 to discharge the pouch-packaged product 100 packaged at the end of the pouch-packaged product production line 200 And is automatically transported by the transporting unit 10 immediately.

The pressing portion 20 presses the pouch packaged product 100 conveyed by the conveying portion 10.

The pressing unit 20 includes a motor 21; And a roller 22 which is rotated by the driving of the motor 21, and which is disposed on the conveying unit 10.

Accordingly, the pouch packaged product 100 conveyed by the conveyance unit 10 is automatically pressed by a process of contacting the lower end of the roller 22. [

The pressing portion 20 further includes a lifting means 23 connected to the roller 22 so that the roller 22 is moved up and down by the operation of the lifting means 23, The degree of pressurization of the pouch packaged product 100 in the container 20 is adjusted.

Here, the elevating means 23 may be of any structure and system as long as it can elevate the roller 22, for example, an air cylinder or a ball screw.

The diffuser 30 diffuses the dust 110 generated from the pouch packaged product 100 by applying air to the pouch packaged product 100 pressed by the pressing unit 20.

The diffusion unit 30 may be any one of a blowing unit and a high-pressure air injection unit, or a combination thereof.

The blowing means may be any device capable of blowing air such as a blowing fan, an air curtain, a sirocco fan, and a cooling fan. The high-pressure air spraying means may include a bellows nozzle, an air knife, a spray nozzle, The air blowing fan 31 and the air knife 32 can be used in combination with the combination of the blowing means and the high-pressure air blowing means, more specifically, the blowing fan 31 and the air knife 32, The dust 110 generated from the pouch packaged product 100 smoothly spreads as air and high pressure air are applied to the pouch packaged product 100 by the operation of the fan 31 and the air knife 32 do. The combination of the blowing means and the high-pressure air spraying means disperses the dust 110 discharged from the poor sealing portion of the pouch-packaged product 100 through the air spray to smoothly scatter the scattered dust 110 So as to be able to reach the detection sensor 42, which will be described below, through the dust collecting part 40.

The dust collecting unit 40 collects the dust 110 diffused by the diffusion unit 30 and senses the flow of the dust 110.

The dust collecting unit 40 includes a duct 41 to which a negative pressure is applied; And a sensing sensor 42 mounted in the duct 41.

At this time, the sensing sensor 42 can be used without limitation such as an electrostatic sensor and a light and dark sensor capable of sensing the flow of the dust 110, but a specific electrostatic sensor can be used. The electrostatic sensor can sense the flow of the dust 110 more sensitively than other sensing sensors and has an advantage of low installation and management cost.

Accordingly, when the dust 110 diffused by the diffusion unit 30 flows along the duct 41, the electrostatic amount is automatically detected when the sensor 110 contacts the sensing sensor 42, for example, the electrostatic sensor .

The dust collecting unit 40 may further include a signal device 43.

For example, the signal device 43 may output an audible or visual signal to the outside when the electrostatic detection value of the electrostatic sensor 42 is equal to or greater than a predetermined reference value, that is, when the pouch-packaged product 100 is defective in packaging. So that it is easy to determine whether or not the pouch-packaged product 100 is poorly packed by the signal from the signal device 43.

The lid 50 blocks external diffusion of the dust 110 diffused by the diffusion part 30.

The lid unit 50 includes a body 51 for receiving the transfer unit 10, the pressing unit 20, and the diffusion unit 30; And a door 52 opened and closed on the body 51 so that the dust 110 diffused by the diffusion part 30 is not discharged to the outside by the body 51 but flows into the dust collecting part 40 Not only is it smoothly collected but also the inside of the door 52 can be confirmed easily by opening the door 52 in case of need.

8, the method for detecting a packaging defect of a pouch-packaged product according to the present invention includes a first step S1, a second step S2, a third step S3, a fourth step S4, ).

The first step (S1) comprises: the motor (11); The pouch packaged product (100) which is discharged from the pouch packaged product production line (200) through the conveying part (10) including the belt (12) running continuously by driving the motor (11) In one direction.

In the first step S1, the belt 12 can adjust the speed according to the product amount without limitation, and more specifically, it can travel at a speed of 10 m / min to 30 m / min.

When the running speed of the belt 12 is less than 10 m / min, the conveying speed of the packaged pouch packaged product 100 becomes relatively slow, so that the packaging failure detecting operation can be delayed. When the traveling speed exceeds 30 m / min, as the conveying speed of the packaged packaged product 100 is relatively increased, the pressurized and dusted flow sensed in conjunction with the conveyance of the pouch packaged product 100 May be insufficient.

The details of the conveying unit 10 are described in the foregoing.

The second step (S2) includes: the motor (21); The roller 22 being rotated by the driving of the motor 21 and being spaced apart from the upper part of the transferring part 10 by the transfer part 10, Thereby pressing the packaged product (100).

In the second step S2, the roller 22 can adjust the position of the pouch-packaged product 100 irrespective of the type of the pouch-packaged product 100, It can be placed at 0.9 times the height.

If the roller 22 is located more than 0.9 times the height of the packaged pouch product 100, the pressure of the packaged pouch product 100 is insufficient and the generation of the dust 110 is insufficient even in a poor packing state And the rollers 22 are located less than 0.75 times the height of the packaged pouch product 100, the pouch packaged product 100 may be overpressurized and damaged.

The details of the pressing portion 20 are the same as those of the previous embodiment.

The third step (S3) is a step in which the pouch packaged product (100) which is pressed by the pressing portion (20) through the diffusion portion (30) including at least one of the blowing means and the high- And diffuses the generated dust 110.

The details of the diffusion unit 30 are the same as those described above.

In the fourth step S4, the duct 41 in which a negative pressure is applied; And collects the dust 110 diffused by the diffusion unit 30 through the dust collecting unit 40 including the sensing sensor 42 mounted in the duct 41 to sense the flow.

When the measured value of the sensing sensor 42 is within the predetermined reference value range in the fourth step S4, the pouch-packaged product 100 may be regarded as normal packing, and the measurement value of the sensing sensor 42 may be When the pouch-packaged product 100 is above a predetermined reference value range, the pouch-packaged product 100 may be referred to as defective packaging.

The details of the dust collecting part 40 are the same as those described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The detection of packaging defects through the packaging defect detection device (A) of the pouch-packaged product according to the present invention will be described in detail as follows.

First, the packaged packaged product 100 discharged from the pouch packaged product production line 200 is transferred by the transfer unit 10. (First step)

The conveyance unit 10 according to the present invention includes the motor 11 and a belt 12 that runs continuously by driving the motor 11 so that the conveyance unit 10 can be used to produce the pouch- As shown in FIG. 2, the pouch-packaged product 100, which is discharged through the end of the pouch-packed product production line 200 by being disposed in connection with the end of the line 200, 10, and more specifically, the belt 12 is mounted on the belt 12, so that the pouch packaged product 100 is automatically transported by the running of the belt 12.

Next, the pouch-packaged product 100 conveyed by the conveyance unit 10 is pressed by the pressing unit 20. (Second step)

The pressing unit 20 according to the present invention includes the motor 21 and the roller 22 rotated by the driving of the motor 21, The packaged product 100 is automatically pressed as it contacts the lower end of the roller 22 as shown in FIG.

At this time, when there is a packing defect in the pouch packaged product 100, that is, when the sealing is defective or damaged, the leakage of the contents, that is, the dust 110, occurs.

However, the dust 110 may occur even when the pouch-packaged product 100 is normally packaged.

That is, the pouch-packaged product 100 may be provided with a pinhole (not shown in the figure) for minimizing the volume by discharging air therein, and the dust 110 may be generated through the pinhole.

However, since the dust 110 generated through the pinhole is insignificant, it is within a predetermined reference value range when the dust 110 is subsequently sensed by the dust collecting unit 40 through the sensing sensor 42, .

At this time, the reference value range is an appropriate value to distinguish the normal product from the commodity which is commercially defective. The numerical value can be set without limitation according to the article and the packaging condition, but in case of the ordinary flour product, 6000TRH or less, specifically 5000TRH or less The reference value range can be set.

On the other hand, depending on the volume of the pouch-packaged product 100, it may be difficult to pressurize the pressurizing portion 20.

That is, when the volume of the pouch packaged product 100 is relatively small, the lower end of the roller 22 and the upper end of the pouch packaged product 100 may be separated from each other, And the relatively bulky pouch packaged product 100 passes between the lower end of the roller 22 and the upper surface of the belt 12 when the bulk of the pouch packaged product 100 is relatively large, So that it is difficult to press the pressing portion 20.

However, in the present invention, the pressing portion 20 further includes the elevating means 23 connected to the roller 22 as shown in FIG. 4, so that by the operation of the elevating means 23, If the volume of the pouch packaged product 100 is relatively small as the roller 22 is lowered through the lifting means 23 when the volume of the pouch packaged product 100 is relatively low, The upper part of the product 100 is narrowed and the roller 22 comes into contact with the pouch packaged product 100 having a relatively small volume so that the pouch packaged product 100 having a relatively small volume is smoothly pressed When the roller 22 is lifted up through the lifting means 23 and the lower end of the roller 22 and the pouch packaged product 100 are lifted up when the volume of the pouch packaged product 100 is relatively large, The upper part is wider, Roller 22 is therefore in contact with relative wrapping the pouch-like article 100 has a large volume in this relatively large the pouch-type packaging product 100 by volume is smoothly pressed.

Next, the dust 110 generated from the packaged pouch product 100, which is pressed by the pressing portion 20, is diffused by the diffusion portion 30. (Third step)

The diffusion unit 30 according to the present invention includes the air blowing fan 31 and the air knife 32. The diffusion unit 30 according to an embodiment of the present invention includes the air blowing fan 31 and the air knife 32, As shown in FIG. 5, the dust 110 is smoothly diffused as air is blown from the blowing fan 31 and the air knife 32 and high-pressure air is applied thereto.

However, when the dust 110 generated from the pouch packaged product 100 flows out to the outside, the flow of the dust 110 in the dust collecting unit 40 may be incorrect.

However, in the present invention, the transfer unit 10, the pressing unit 20, and the diffusion unit 30 are received in the body 51 of the lid unit 50, The flow of the dust 110 in the dust collecting part 40 is relatively accurately measured since the dust is mostly blocked off from the dust.

Next, the dust 110 diffused by the diffusion part 30 is collected by the dust collecting part 40 and the flow is sensed. (Step 4)

The dust collecting unit 40 includes the duct 41 in which a negative pressure is applied and the sensing sensor 42 mounted in the duct 41. The dust collecting unit 40 diffuses As shown in FIG. 6, the dust 110 is collected in the duct 41 and then flows along the inside of the duct 41. As the dust 110 contacts the sensing sensor 42, Is detected.

At this time, when the measured value of the sensor 42, for example, the electrostatic amount measurement value through the electrostatic sensor is within a predetermined reference value range, the packaging of the pouch packaged product 100 may be normal, If the measured value of the sensor 42, for example, the electrostatic amount measurement value through the electrostatic sensor, is equal to or greater than a preset reference value, the packaging of the pouch packaged product 100 may be considered to be defective. ), Thereby preventing the reliability of the product from being deteriorated due to the distribution of the defective packaging product.

On the other hand, if the measured value of the sensing sensor 42, for example, the electrostatic amount measurement value through the electrostatic sensor, is not less than a predetermined reference value, that is, if the determination result is not delivered to the outside when the packaging is defective, 100) of the pouch-packaged product 100 can be difficult to select, and the pouch-packaged product 100 can be continuously produced through the pouch-packaged product production line 200.

However, in the present invention, when the measured value of the sensing sensor 42, for example, the electrostatic amount measurement value through the electrostatic sensor is equal to or greater than a predetermined reference value, in other words, the pouch- (43) for transmitting an auditory or visual signal to the outside when the pouch-packaged product (100) is packaged, and the signal of the signaler (43) The pouch-packaged product 100 is easily selected, and the production of the pouch-packaged product 100 through the pouch-packaged product production line 200 is discontinued to prevent the occurrence of further packaging defects .

Hereinafter, an experimental example showing a method of detecting the packaging defect of the pouch packaged product 100 through the packaging defect detection apparatus A of the pouch packaged product according to the present invention will be described.

[Experimental Example 1]

Air was applied through a blowing fan and an air knife of the diffusion part during the pressing process by the pressing part to diffuse the dust generated from the normal sealing product and the dust diffused through the duct of the dust collecting part in the diffusion process by the diffusion part, And the electrostatic charge due to dust flow was measured with an electrostatic sensor.

At this time, the entire process was repeated four times in succession, and the result is shown in the following graph 1.

[Graph 4]

[Experimental Example 5]

The test was carried out in the same manner as in Experimental Example 1, except that 12 low-defective sealing products of pinholes previously selected through the belt of the conveying portion were transferred. The results are shown in the following Graph 5.

[Graph 5]

In the case of the normal packaged product, it can be seen that the electrostatic amount measurement value through the electrostatic sensor is within a predetermined sensing range, that is, within the reference value range. In case of a badly packaged product, (A) of the pouch-packaged product according to the present invention and the packaging defect of the pouch-packaged product using the same.
