Description

The present invention relates to a packaging package made of corrugated cardboard containing a plurality of containers filled with a fluid such as a liquid beverage such as juice or a gel-like food, or a plurality of packaging boxes containing a plurality of filled containers. A product pass / fail judgment device in the package to be used for inspecting whether there is a defective container in which the fluid of the contents leaks from the filled container inside the package; and The present invention relates to a product quality judgment method using this product quality judgment device .

  A pouch in which a laminated sheet is pasted into a small sachet, and a container that is sized to carry a cap with a drinking cap with a cap attached to the side heat seal part and filled with fluid such as juice or gel food Many types of products are in circulation. In a container in which such a container body is formed of a laminated sheet and a drinking mouthpiece is sandwiched between heat seal portions, 100% inspection is performed to check whether or not the contents filled before the product shipment is leaking.

The inspection itself is performed as follows, for example. The product before entering the inspection process is a form in which a plurality of packaging boxes containing a plurality of pre-filled containers are collected and stored in a single packaging package, and in this form, from the manufacturing process to the inspection process Have been sent to.
The packaging and packaging body is made of corrugated cardboard, and the pair of flaps are fixed with tape so as to straddle the two flaps that face each other on the top surface and are folded to become the outer surface side and close the top surface. In addition, the bottom surface of the packaging package is closed in the same manner. And the packing package sent to the inspection process cuts the tape on the top surface by the inspector and opens the top surface, and the inspector takes out the inner packaging box and opens it, and the container remains in the state Thus, the inside of the packaging box is visually inspected to see if there are any traces of the contents adhering to the outer surface of the container.
The packaging box that is judged as having no leakage of contents without being confirmed to be attached to the inner surface of the packaging box or the outer surface of each inner container is closed, and the packaging box that has been judged as having no leakage is repacked in the above-mentioned packaging body. The face is blocked. Then, the inspected product is shipped in a state of being housed in a packaging package.

  Inspection for leakage before shipment is not limited to products using the above-described pouch-type containers. For example, is a carton packed with a plurality of beer cans (carton sent out from the manufacturing process) turned upside down and left in the sealed space to detect alcohol components in the air in the sealed space? A method of measuring whether (Patent Document 1) or a retort pouch container is placed in a chamber to generate a differential pressure between the pressure inside the retort pouch container and the pressure in the chamber, and the identification contained in the air in the chamber There has been proposed a method (Patent Document 2) for determining whether or not a retort pouch has leaked so that components can be detected by being extracted from the chamber or the chamber.

However, when checking the leakage of the filling of the pouch-type product with a mouthpiece, the above-mentioned carton is turned upside down and left in a sealed space, and the target container is put in the chamber. There is a problem that the technique for inspecting the presence or absence of leakage is very complicated.
In addition, there is a method of performing an image inspection using an optical camera to inspect the leakage of the filling material in a product equipped with a drinking tool, but the low detection accuracy is a problem. In other words, the trace that can be detected by the optical camera is only the range photographed by the optical camera, and there is a problem that inspection cannot be performed at a portion outside the frame of the optical camera.
From this point of view, it is very useful to use the presence or absence of odor components or the like for the determination of leakage. However, the method described above is currently used for inspection of leakage of fillings in products equipped with drinking mouthpieces. Yes.

  On the other hand, this manual method has a problem in that the inspection work becomes complicated because the package package sent out from the production line is opened and the package package is closed again after the quality determination. Also, in order to inspect the presence or absence of adhesion marks of the contents visually, it is necessary for the inspector to gain experience so as not to miss the adhesion marks, but it is difficult to train the inspectors. There is a problem and there is a need for improvement.

  For this reason, the applicant's product quality is intended to enable the applicant to inspect for the presence or absence of adhesion of the contents without requiring manual labor as shown in Patent Document 3. A determination device has been proposed first. In this proposal, the packing and packaging body has a pair of flaps facing each other in a direction orthogonal to a direction in which the pair of outer flaps are opposed to each other, and the pair of flaps on the top surface are fixed by a non-ventilable tape. The flap is folded down on the inner side of the top surface below the outer side flap, and the space between the inner side flap and the outer side flap can be vented. In addition, the top surface is closed by allowing ventilation on the side of the top surface along the direction in which the outer side flaps face each other. Then, the product pass / fail judging device covers the other part of the packing and packaging body so as to allow ventilation, covers the other part so as not to allow ventilation, and discharges by pressing the packaging and packaging body. A sensor determines whether or not there is an odor component (an odor component generated when volatilized from the contained contents) in the air in the package.

It is explanatory drawing shown in the state which looked at the principal part of examination technology from the side. It is explanatory drawing which shows an example of a packing packaging body. It is explanatory drawing which shows the state which a pressing means pushes the top | upper surface of a packaging body into a package, and a nozzle faces a packaging body. It is explanatory drawing which shows roughly the odor detection means in examination technique . It is explanatory drawing which shows the example of implementation of this invention .

Will be explained based on techniques discussed upon reaching the present invention initially FIGS. 1 to 5.
FIG. 1 shows a product quality determination device. Then, the packaging and packaging body A to be inspected by the product quality determination device 1 will be described first. This packaging and packaging body A is composed of a cardboard box and is used as an outer box. FIG. A plurality of cardboard packaging boxes B are accommodated therein, and the packaging box B is not shown, but is filled with a plurality of filled containers filled with fluids, for example, mouthpieces. Containers with tools attached to a pouch-type container body are in an aligned state. The fluid filled in the container is a juice or a gel-like food, and this fluid contains an odor component such as a fragrance, and one example thereof is ethanol.

(Packaging packaging)
The package A itself is of the type conventionally used, and as described above, the pair of flaps a on the outer surface side are folded opposite each other at the top surface b, and the end portions of each other face each other. The top surface is closed, and a pair of flaps a are affixed with a tape C that cannot be vented along the abutting portion c so as to straddle the abutting portion c of the end portion to form a closed top surface b. Below the pair of flaps a on the outer surface side, there is another pair of flaps d facing each other in the direction orthogonal to the facing direction of the flaps a. It is folded down so that it may become the inner surface side in the surface b, and the edge parts of this flap d are spaced apart without abutting. Each top surface side portion of the side along the direction in which the two flaps a on the outer surface side face each other is not attached to the tape. Note that the bottom surface of the package A is also closed with the same configuration.
FIG. 3 is a view showing the package A, and the position 4a of the pressing plate of the pressing means of the product pass / fail judgment apparatus described later and the position 9a of the piercing nozzle of the odor detecting means are also shown.

(Conveying means)
The product quality determination apparatus 1 of the studied technology includes a transport unit 2 including an endless transport mechanism such as a belt conveyor that transports the packing and packaging body A in one direction. The transport means 2 has one end side (on the front in the drawing) as a package stop position for temporarily stopping the package A, and immediately before the package A reaches the package stop position, the transport mechanism The stopper 3 positioned corresponding to the end of the package rises to receive the packaging body A, and when the packaging body A comes into contact with the stopper 3, the transport mechanism stops the transportation, and the packaging body A becomes the packaging body. It stops at the stop position.

(Pressing means)
And the product quality determination apparatus 1 stops the packaging body A at the packaging body stop position, takes out the air inside the packaging body A, and flows the air filled in the container inside the packaging body A into the air. Detecting whether or not there is an animal odor component, but matching the end where the outer surface side flap a of the top surface b of the packaging body A stopped at the packaging body stop position is butted A pressing means 5 for pressing the closed top surface b of the packaging body A stopped at the packaging body stop position is provided by a pressing plate 4 that can be raised and lowered corresponding to the part c.

  As shown in the figure, the pressing means 5 is supported by a gantry 6 that spans the width direction of the conveying means 2 so as to straddle the package stop position of the conveying means 2, and is attached to the gantry 6. The pressure plate 4 can be raised and lowered by the action of the air cylinder 7 and is directed toward the abutting portion c in the center of the top surface b of the packaging package A when stopped at the packaging body stop position. Is performed to push the top surface b of the packaging body A, and before the packaging body A reaches the packaging body stop position, the product pass / fail judgment for the packaging body A at the packaging body stop position is completed. Later, the press plate 4 is provided at a height position that does not hinder the conveyance of the package A.

(Pressing plate)
The pressing plate 4 of the pressing means 5 is for pushing the top surface b of the packing and packaging body A to increase the pressure of the air inside the packing and packaging body A so that air can be easily taken in by the odor detection means described later. Yes, so that the top surface b of the package A can be slightly recessed, and the length in the direction perpendicular to the butting portion c is shorter than the length of the butting portion c of the top surface b. The length of the packing package A is shorter than the length in the direction perpendicular to the butting portion c (see FIG. 3). Then, in order for the odor detection means described later to more easily take in air from the inside of the package, the correspondence of the abutting portion c which is higher than the portion e between the end portions where the pair of flaps d is separated from each other. The size covers the portion f. Of course, from the above, the lowering amount of the pressing plate 4 is set in advance so as not to damage the corrugated cardboard material of the packing and packaging body A, the packaging box and the container accommodated therein.

  The position where the pressing plate 4 hits the top surface of the packaging body A is set so that the corresponding part f of the butted portion c is centered, and the packaging body A having the same dimensions is determined. When the pressing plate 4 is stopped vertically at the (packing body stop position), the pressing plate 4 is properly positioned to correspond to the corresponding portion f, or the packing body A is stopped at the packing body stop position. The lowering position of the pressing plate 4 may be adjusted so as to correspond to the position of the corresponding portion f. Further, when the top surface b of the packaging package A is depressed, it is recessed into a substantially concave shape, and the pressing plate itself is made flexible as shown in FIG. 4 so as to follow this concave shape. Is good.

In the example of the examination technique , the top surface b of the packaging body A is pushed by the pressing means 5, but either the long side surface or the short side surface of the packaging body A without moving the position of the packaging body A. Alternatively, the long side surface and the short side surface may be pressed simultaneously with the pressing of the pressing means 5 to increase the pressure of the air inside the packaging body A. In this way, odor detection described later is performed. The air can be more easily taken in by the means.

(Odor detection means)
The product quality determination device 1 has an odor detection means 8. The odor detecting means 8 includes three piercing nozzles 9 attached so as to protrude downward from the upper surface to the lower surface of the pressing plate 4, and the piercing nozzles 9 are connected via pipes, and the piercing nozzle 9 A suction spray circuit unit 10 that performs a suction operation so that air can be drawn, and a sensor 11 connected to the suction spray circuit unit 10 are provided.

  The three piercing nozzles 9 are arranged in a straight line so as to correspond to the corresponding portion f at the butt portion c pressed by the pressing plate 4 (see FIG. 3). When the packaging body A is located at the package stop position and the pressing plate 4 descends toward the abutting part c by the action of the air cylinder 7 of the pressing means 5, the abutting part c is pressed down. The nozzle C is provided so that the tip of the nozzle faces the inside of the package A from the corresponding part f through the tape C attached thereto.

  The suction spray circuit unit 10 performs an operation of taking air inside the packaging package A from the piercing nozzle 9 when the pressing plate 4 pushes down the top surface b of the packaging package A. When the pressing plate 4 is lowered by a predetermined amount of depression so that the top surface b of A is recessed, the air inside the packaging body A is sucked from the piercing nozzle 9. Then, the air taken in by sucking is sent out toward the sensor 11 and blown to the sensor 11 without returning to the nozzle 9 side.

  Every time the packing package A stops at the packing body stop position, air is sucked from the packing package A, and the suction is performed while the pressing plate 4 pushes the top surface b of the packing package A, The suction by the piercing nozzle 9 stops before the predetermined pressing time of the pressing plate 4 ends. Since the top surface b is pushed by the pressing plate 4 at the time of taking in the air inside the packaging and packaging body A in this way, the pressure of the air inside the packaging and packaging body A is slightly increased. In this state, air is pierced from the piercing nozzle 9. Since the suction is performed, the resistance to the suction itself is reduced and the intake of the air inside the package A is ensured. Further, since each of the piercing nozzles 9 directly faces the inside of the packaging body A, the air inside the packaging body A can be taken in smoothly.

  The odor detection means 8 detects the presence or absence of an odor component in the air using a sensor 11 to which air is blown by the suction blowing circuit unit 10. If the fluid filled from any container in any of the packaging boxes is leaking inside the packaging package A, the fluid that leaked out contains odor components. The odor component is volatilized and mixed with the air inside the package A. When the air containing the odor component is blown onto the sensor 11, the odor component is detected by the sensor.

  The sensor 11 is connected to a control device 12 that receives a signal corresponding to the presence or absence of an odor component from the sensor 11, and the control device 12 determines whether or not there is a defective package in the package A. Judgment is made. The determination result itself can be expressed by sound generation by a buzzer or character information display by a monitor. Note that the air in the path from the piercing nozzle 9 to the sensor 11 via the suction blowing circuit unit 10 is replaced with clean air for each inspection.

  Each operation | movement according to the movement to the packaging body A of each of the conveyance means 2, the press means 5, and the odor detection means 8 is controlled by the said control apparatus 12. FIG. And when the odor component is detected by the odor detection means 8 from the air of the package body A at the package body stop position, the control device 12 gives an odor to the package body A at the package body stop position. The information that the component is detected is associated, and when the odor component is not detected, the information that the odor component is not detected is detected with respect to the package A in the package stop position. It is provided to manage in association with each other.

(Defective product discharge means)
As shown in the figure, a defective product discharging means 13 is provided in front of the conveying means 2. The defective product discharging means 13 has completed the operation of the odor detecting means 8 and has already judged the quality of the internal product based on the presence or absence of odor components, so that the pressing plate 4 does not interfere with the movement of the packaging body A. The table 14 that receives the packaging A that has been conveyed by the conveying means 2 that has resumed the conveying operation after being moved to the standby position, and temporarily stops the conveyance of the packaging A from the next process so that it can be stopped. When the packaging body A located on the side of the table 14 and associated with the information that the odor component is detected by the control device is stopped on the table 14, the table 14 And a delivery device 17 for extruding the packing and packaging body A to the defective product sorting and conveying means 16 arranged in parallel with the direction to the second conveying means 15 side to the next process arranged side by side. Also It is.
The defective product discharge means 13 does not stop when the packaging body A associated with the information indicating that no odor component is detected by the control device is sent from the transport means 2 to the table 14. It is provided so that the packaging body A may be sent out to the two conveying means 15.

  In this way, the defective product discharging means 13 divides the packaging and packaging body in which the odor component is detected in the odor detecting means 8 and the packaging and packaging body in which the odor component is not detected into corresponding defective product sorting and conveying means 16, Since the second transport means 15 is sorted and transported from the transport means 2, it is possible to reliably separate defective products without manual intervention.

In the example of the examination technique, the defective product discharge means 13 has been described as being composed of the table 14 and the delivery device 17. However, the defective product discharge means 13 is not limited to this example, and includes a robot arm mechanism. By the control of the control device, the packaging unit associated with the information in which the odor component is detected and the packaging unit in which the information in which the odor component is not detected are associated from the transport unit 2. Each may be configured to distribute toward a predetermined position.
Further, the bottom surface of the packaging and packaging body is closed in the same manner as the top surface. However, since the entire bottom surface is covered with the transport surface of the transport means 2, air from the bottom surface side is covered. Leakage is prevented.
Furthermore, although the example of the said examination technique showed the example which accommodated the several packaging box inside the packaging package, and accommodated the several container in the storage box, the form of a packaging package is limited to this example Is not to be done.

And in the example of the said examination technique , although one packing packaging body A is stopped and inspected at the one end side of one conveyance means 2, it is not limited to this example, and there are a plurality of conveyance means 2. Each of the transport means is provided with the defective product discharge means 13 that receives the packaging package A in the same manner as the above-described examination technique , and stops at the package stop position in each of the transport means 2. The pressing means 5 is provided so as to correspond to each of the packing packages A, and furthermore, one odor detecting means 8 is provided with a pipe extending to each packing body stop position side, and a piercing nozzle 9 at the end of the pipe is provided. As shown in the above embodiment, it may be attached to the pressing plate 4 of the pressing means 5 for pressing the top surface of the packaging body A, and air may be taken in from the packaging body at each of the plurality of packaging body stop positions. .

Next, if this invention is demonstrated based on FIG. 6, the product quality determination apparatus 1 will detect the odor with respect to the packaging body stopped in the packaging body stop position, and the surroundings of the packaging body will be positively pressurized with clean air. It is performed in an environment that is in a state. As shown in FIG. 6, the simple chamber 18 surrounding the packaging package A stopped at the packaging body stop position is included so as to include a portion that penetrates the piercing nozzle on the top surface of the packaging body A stopped at the packaging body stop position. Provided corresponding to the package stop position, the simple chamber 18 is transported to the package stop position by the transport means 2 and is allowed to pass through the package package transported from the package stop position toward the table 14. A box made of a synthetic resin plate or the like having a passage opening is arranged, and an activated carbon filter 21 and a blower 22 are provided in a fresh air introduction pipe 20 with respect to a clean air introduction opening 19 opened in a part of the simple chamber 18. Are connected. In the example shown in FIG. 6, the clean air g is fed from the clean air inlet 19 into the simple chamber 18, and the pressing plate 4 and the piercing nozzle 9 protruding from the lower surface of the pressing plate 4 are positioned. By being performed in the simple chamber 18 surrounding the space to be performed, the atmosphere in the simple chamber is provided in a positive pressure state. In this way, the piercing nozzle 9 only sucks clean air g and air in the packing and packaging body, and even if other odor components exist in the atmosphere around the outside of the simple chamber. In addition, the false detection that the odor component around the outside of the simple chamber is taken into the odor detection means 8 is eliminated, and the accuracy of the determination and inspection for the presence or absence of the odor component in the package to be inspected is further improved.
