Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method for filling and packaging a granular material such as rice grain in a small bag for retail sale.

[0002]

2. Description of the Related Art As a packaging device for packing and packaging powder particles, especially rice particles, into bags for retail sale, there is, for example, Japanese Patent Laid-Open No. 56-56.
The one disclosed in Japanese Patent No. 6671 is known. These are by the applicant of the present application, and various devices have been devised so that the rice grains can be efficiently packaged according to various brands, filling sizes, etc. The packaging using these is roughly as follows. Has been done.

That is, as shown in FIG. 6, the packaging device 1
Is provided with a bag making mechanism unit 2, a supply mechanism unit 3, a filling mechanism unit 4, and a control unit 5 using an electronic circuit.
In the bag making mechanism section 2 under the control of 1., the material film fed out from the film bobbin is cut into a predetermined length based on the pitch mark attached to the material film and sealed to make a bag, and then the bag is made. The bag is supplied to the filling mechanism section 4 by the supply mechanism section 3, the bag is filled with rice grains in the filling mechanism section 4, and then the opening of the bag is sealed and discharged. As a result, rice grains are packed. In addition, the integrated control device 6 shown in the figure integrally manages a plurality of packaging devices when they are operated at the same time. Is issued, and each packaging device automatically advances the packaging based on this instruction.

That is, in this packaging device, the human hands are mainly involved only in setting the film bobbin on the packaging device, and thereafter, under the control of the control unit according to the type of the film bobbin set. The size of the bag to be manufactured is automatically determined, and the processing is automatically advanced. Therefore, if an operator makes a mistake in setting the film bobbin to be set, there is a possibility that many erroneous packages will be produced.

Therefore, various investigations have been made on a method for effectively preventing a film bobbin from being set incorrectly. As a result of technological advances in the distribution industry in recent years, most of the packaging bags have a distribution control indicating the brand of rice grains in the packaging content. It has been found that a bar code for use in advance is attached in advance, and by using this bar code, it is possible to effectively prevent a mistake in setting the film bobbin. The present invention has been made as a result.

[0006]

That is, according to the present invention, a powdery or granular material which can effectively prevent a film bobbin from being set incorrectly by utilizing a bar code for distribution management attached to a packaging bag. It is intended to provide a packaging method.

[0007]

According to the method of packaging a powdery or granular material according to the present invention, a plurality of packaging devices each having a bag making mechanism section, a supply mechanism section, a filling mechanism section and a control section are controlled by an integrated control device. It operates according to a command and advances the packaging of powder and granules, and is fed from the film bobbin in the bag making mechanism unit under the control of the control unit based on the command from the integrated control device in each packaging device. The material film is cut and sealed one after another to make bags continuously, and the bags manufactured by the bag making mechanism are supplied to the filling mechanism by the supply mechanism, and the powder particles are formed in the bag at the filling mechanism. After filling, the bag opening is sealed and discharged.
Further, an intermediate control unit equipped with a reading means for reading a bar code is used, and the bar code preprinted on the material film corresponding to the type of powder or granular material to be filled is set every time the film bobbin is set in the packaging device. Simultaneously with the reading by the reading means of the intermediate control unit, it is determined based on the bar code whether or not the type of material film indicated by the read bar code matches the type of material film instructed by the integrated control device. It is done like this.

This packaging method is intended for the case where a plurality of packaging devices are simultaneously operated under the control of the overall control device, and the material is placed between the overall control device and the control section of each packaging device. An intermediate control unit for taking in the bar code from the film is interposed, and whether or not the film bobbin actually set matches the material film instructed by the integrated control device is based on the bar code taken in by the intermediate control unit. Since it is automatically determined by the above, it is possible to surely prevent a mistake in setting the film bobbin.

In the present invention, in the packaging method as described above, the film data such as the sealing condition, the kind of the granular material, the filling amount, etc. which are preset for each material film specified by the bar code are associated with the bar code. The film data file that has been filed is stored in advance in the file storage section of the intermediate control unit, and if the judgment result of the material film type based on the bar code is correct, the film data file corresponding to the read bar code is stored. It is transmitted from the file storage unit to the control unit of the corresponding packaging device, and the packaging device is controlled based on the film data stored in the transmitted film data file.

This is for more rational operation of the entire system by more effectively utilizing the intermediate control unit for taking in the bar code. That is, since the film data is made into a file with a bar code as an index and the film data is set in the packaging device by this film data file, it is not necessary to input the film data each time, and the operator's work amount is reduced. Can be reduced. Also, after confirming based on the bar code that the set film bobbin is correct, the film data file is taken out based on the bar code and transmitted to the control unit of the packaging device, so that the film data set can be reliably stored. It is possible to improve the sex. Further, since the film data file is stored in the intermediate control unit, the load on the central control unit can be reduced.

When the film data file is used as described above, the judgment of the correctness of the film bobbin based on the bar code is made by directly comparing the bar codes with each other, that is, by the bar code actually taken in from the material film by the intermediate control unit. In addition to the comparison with the bar code of the material film instructed by the control device, the film data file contains an index corresponding to the bar code in the form of a product code, for example. It is also possible. The latter method is particularly effective when the bar code is for managing the store and does not necessarily match the production management of the packer.

The system for preventing the mistaken setting of the film bobbin by using the bar code as described above can be effectively used when one packaging device is used. In this case, the bag-making mechanism unit, the supply mechanism unit, the filling mechanism unit, and the control unit are provided, and under the control of the control unit, the material film fed from the film bobbin in the bag-making mechanism unit is sequentially cut and While sealing and making bags continuously,
The bag manufactured by this bag-making mechanism unit is supplied to the filling mechanism unit by the supply mechanism unit, and after filling the bag with the granular material in the filling mechanism unit, the opening of the bag is sealed and discharged. Regarding the packaging method for packaging powder and granules using the existing packaging device, an intermediate control unit equipped with a reading means for reading a bar code shall be used, and the material film shall be selected according to the type of powder or granules to be filled. Each time the film bobbin is set on the packaging device, the bar code pre-printed on is read by the reading means of the intermediate control unit, and at the same time,
Whether or not the type of material film indicated by the read bar code matches the designated type of material film is determined based on the display content displayed on the display unit of the intermediate control unit based on the read bar code. I am trying.

That is, when using the packaging device in units of one unit, unlike in the case of using a plurality of units using the integrated control device, the packaging instruction is given in the form of, for example, a slip, and therefore, in this slip, The instruction and the display content of the display unit of the intermediate control unit are compared and confirmed.

Also for such a packaging method, the file data file system can be utilized in the same manner as described above.
