る。2. Description of the Related Art An example of a conventional packaging apparatus (horizontal pillow packaging apparatus in the illustrated example) is shown in FIG.
As shown in the figure, the belt-shaped film 2 is continuously pulled out from the raw film 2a and guided to the bag-making machine 3, and the band-shaped film 2 is made into a tubular bag by passing through the bag-making machine 3. .

る。On the other hand, the article to be packaged 4 is pushed by a pushing finger 6 of a supply conveyor 5 arranged on the upstream side of the bag making machine 3.
It is conveyed at a predetermined pitch, and is sequentially supplied into the bag making device 3, that is, into the tubular film 2 'formed into a tubular shape. Then, the supplied packaged object 4 is transported together with the tubular film 2 ′, and in the middle of the transport, the overlapped ends of both side edges of the tubular film 2 ′ are heat-sealed by the center sealer 7. 8, the tubular film 2 'between the front and rear to-be-packaged objects 4 is sealed in the horizontal direction and cut to manufacture the package 9. Then, the package 9 is transported on the unloading conveyor 10.

同様の構成となっている。As shown in FIG. 1, a top sealer 8b is attached to a rotating shaft 8a, which is vertically opposed to and sandwiches a cylindrical film 2 ', and which rotates synchronously. Each time the top sealer 8a makes one rotation, the upper and lower top sealers 8b abut and press against each other with the film interposed therebetween. At the time of the abutment, the film is heated, pressurized and welded, and cut by a built-in cutting blade. . A heater and a thermocouple are built in the top sealer 8b, and the heater is turned on / off based on the output of the thermocouple so that the surface of the top sealer 8b has a predetermined temperature. The heating mechanism and temperature control of the center sealer have the same configuration.

It does not measure the temperature of the surface of the top sealer 8b in contact with the heater, that is, the temperature applied to the cylindrical film 2 ', and thus controls the temperature of the heater in consideration of the temperature difference generated between the two. ing. Therefore, if the temperature difference is significantly different from the range considered, an unsealed portion may be generated due to insufficient heating temperature of the tubular film 2 ', or the film may be excessively heated and melted more than necessary to alter the quality. Various sealing defects such as a decrease in adhesive strength are generated.

きる。また、上記押さえつける処理を機械・装置により
行うこともできる。[0006] As a conventional method of judging the quality of the seal, for example, an inspector is arranged on the side of the carry-out conveyor 10, and the inspector places the main body portion (the seal portion) of the package 9 to be conveyed on the carry-out conveyor 10. (The part that is swelled by storing other items to be packaged) from above. In other words, when the package 9 is sealed, the inside of the package 9 is a sealed space, so that the main body of the package 9 is not crushed. By pressing down, the air existing in the package 9 is pushed out, and the package 9 is crushed. Therefore, it can be determined whether or not the seal is made based on whether or not such a crushing occurs. Further, the pressing process can be performed by a machine / apparatus.

An inspector must be resident and cannot perform automatic discrimination. In addition, since processing and judgment are performed manually as described above, for example, when it is determined as a defective product (seal defect) as a result of the inspection, the defective product is to be eliminated, but the elimination process is also performed directly or manually. The inspector depresses a predetermined switch to switch the transport path of the defective product, leading to a discharge chute or the like, and the elimination process becomes complicated.

い。Further, depending on the form of the package, there are many cases where the package is not filled with air. Even if the package is sealed, the main body of the package comes into contact with or close to the packaged object, and When a part is pressed, a packaging film may be pushed until it is pressed against a packaged object with a predetermined urging force. Then, in this case, if the packaged object is soft, such as bread, for example, the packaged object is deformed by the urging force. Therefore, in the case of a package including such an article to be packaged, the above-described inspection cannot be performed.

It is still another object of the present invention to provide an automatic packaging method and apparatus which are versatile and can be accurately determined with a simple configuration.

備えて構成した（請求項１）。In order to achieve the above object, an automatic packaging apparatus according to the present invention covers an object to be packaged with a packaging film and heat seals a predetermined overlapping end portion of the packaging film. After the heat sealing or at the same time as the heat sealing, assuming an automatic packaging apparatus for manufacturing a package by cutting a predetermined position of the packaging film in the transverse direction with respect to the traveling direction, heat sealing the predetermined overlapping end portion. Monitoring means for monitoring the physical state of the seal surface immediately after the sealing, and determining means for determining the presence or absence of a seal failure based on a signal output from the monitoring means; An output means for notifying an abnormality at least when the result of the judgment by the judgment means is a sealing failure is provided (claim 1).

Here, the physical state includes everything that shows a physical difference between a case where the seal is normally performed and a case where the seal is defective. For example, the physical state is a temperature, a transmittance, a reflectance, or the like. There is optical information. In addition, the present invention is not limited to those appearing on the surface, but may be a state inside the film such as a molecular structure at a boundary surface portion where a film overlap end is detected by X-ray analysis.

ールの良否を弁別できる。That is, in the case of heat sealing, a sealer heated to a certain temperature is brought into contact with the packaging film, and a predetermined heat is applied to melt the bonding surface between the overlapping ends of the packaging film. And, even if the heat to be applied is small or too large, the sealing failure occurs. Therefore, the sealing surface of the film immediately after the sealing is heated to a predetermined temperature by being heated by the sealing means. Therefore, if the temperature is a predetermined temperature (including a certain range), it can be estimated that heating has been performed under a desired temperature condition, and it can be determined that the seal has been performed normally. Conversely, if the temperature of the sealing surface is too low or too high, it can be determined that sealing failure has occurred. As described above, the temperature, which is physical information, differs depending on whether or not the seal is defective. Therefore, the quality of the seal can be discriminated by detecting the temperature.

Therefore, the transmittance and the reflectance differ depending on the degree of the thermal fusion. Therefore, optical information (physical information) such as transmittance differs depending on whether or not the seal is defective.
Based on this, the quality of the seal can be discriminated.

That is, the materials constituting the film are bonded to each other at the boundary between the bonding surfaces, and the bonding state of the molecules is changed. Therefore, it is possible to discriminate whether or not the seal is defective by detecting this.

シール部分を抽出する必要がある。The function of the judgment unit 13b will be described, for example, as shown in FIG. That is, the imaging area of the sensor 12 is an area including the seal portion 9a of the package 9 as shown in FIG. At this time, when roughly classified, there are a method of setting an area A where only one seal portion 9a is imaged and a method of setting an area B where both seal portions 9a and 9a are imaged at the same time. The background portion and the main body portion of the package 9 are imaged. In particular, when imaging the area B, since there are many unnecessary parts, it is necessary to reliably extract the seal part.

データを抽出するようにしてもよい。First, a seal portion in the image stored in the image memory 13a is extracted (ST1). In this extraction processing, the background portion is the unloading conveyor 10 and the temperature is low, while the package 9 (the seal portion 9a) is at a high temperature, so that the color tone is different. Therefore, since the change in color tone is large at the boundary between the two, the seal portion can be extracted by performing edge extraction processing or the like. The passage timing of the package 9 can be easily and accurately known by acquiring, for example, zero position information of the rotation of the end sealer of the end seal device 8. Therefore, the image data in the window set in advance according to the package may be extracted according to the timing.

When the process is executed according to the flow shown in FIG. 4, the seal portion 9a is obtained in step 1, and information on the color tone in that region is obtained. Then, in the example shown in the drawing, since the entirety of the seal portion 9a is red, the color tone X is recognized as a normal range, and the seal is determined to be good. Also, when executed according to the flow of FIG. 6, the area of red X is acquired in step 11, and
Since the shape of the acquired area substantially matches the shape of the seal portion 9a, it is determined that the seal is good.

Here, it is assumed that the color tone X1 in the central region corresponds to a temperature lower than the temperature in the normal range. Then, in the flow of FIG. 4, since the area of the color tone X1 outside the normal range exists in the area of the seal portion 9a, the determination in Step 3 is No, and the seal is determined to be defective. In the flow of FIG.
Since the two regions of the normal color tone X acquired in the step 2 are different from the shape of the seal portion, the determination in step 12 is N
It becomes o, and it is determined that the seal is defective.

Since area 2 exists, the determination in step 3 is No, and it is determined that the seal is defective. In the flow of FIG. 6, since the red region cannot be extracted in step 11, the shape is naturally not a predetermined shape, and it is determined that the seal is defective, and abnormal output is performed.
