For example, regarding the packaging of rice, the packaging form of rice these days has become considerably complicated depending on the consumption structure of rice.

That is, recently, in response to the diversification of the consumption structure, each rice grain retailer has begun to provide a variety of unique products based on their own processing and blending, and also regarding the packaging capacity of each consumer. There is a growing number of different types to suit your needs.

And for that reason, it is necessary to classify a very large number of types of packaging products that are produced by combining brands and packaging capacities,
In other words, it is required to produce various kinds in small quantities. Moreover, the packaging classification for many types is a type in which the type change is required many times during one day of operation.

In response to such changes in packaging form, conventional packaging systems have been improved and devised to some extent.

<Problems to be Solved by the Invention> However, conventional packaging systems have not been able to sufficiently cope with this.

That is, in such a packaging form, various types of packaging films classified according to the packaging capacity and material given by the width size and length size of the bag, the printing pattern corresponding to the brand, or the like are used properly. However, the conventional packaging system is not sufficient for this model number changing work, and it requires a lot of time and labor, and it is sufficiently satisfactory in terms of the efficiency of the required small-lot production. Was not.

In view of this, the present invention aims to provide a packaging system that can change the model number of a packaging film quickly and automatically with almost no manpower, which is the most important factor in the production of various kinds in small quantities. It is a thing.

<Means for Solving the Problem> Specifically, the model numbers are classified according to the type of the granular material to be packaged, the packaging capacity, and the like, and a model number code indicating the model number is attached and the model number is determined. A film bobbinized packaging film with size marks attached at predetermined intervals and wound in a long length shall be used, and the packaging film delivered from the film bobbin shall be sequentially cut and cut based on a command from the control mechanism. A method for packaging powder and granules, which comprises sealing and continuously forming bags, and sequentially filling the powder and granules and sealing the openings in the bags that have been continuously formed, and is a film bobbin of various model numbers. A large number of film bobbins are stored in the stock means, and the film bobbin of the model number corresponding to the command from the control mechanism is automatically selected from the film bobbin group of the stock means based on the model code. The film bobbin should be sent to a backing means, and the film bobbin should be positioned at a predetermined position by chucking the film bobbin, and then the film should be unwound from the film bobbin. The unwound film should be made into a bag by detecting the size mark. By determining the length size of the bag, the cutting / sealing means is automatically moved to the corresponding position determined according to the determined length size, and the film is cut / sealed by this cutting / sealing means. Of the powder and granules, which are made by continuously manufacturing and sequentially filling and sealing each of the bag-manufactured bags with the powder and granules of the type and capacity based on the command from the control mechanism. A packaging method is provided.

The film introducing portion 13 is for feeding the film F out of the film bobbin B _x which is centered in both the vertical and horizontal directions and guiding it into the bag making means 4, and is rotatable as shown by an arrow Y. The guide lever 16 is rotated upward at a predetermined timing, and the idler roll 17 presses the above-mentioned introduction tongue portion H against the feed roller 18, and the film F is fed into the bag making means 4 by the feed force of the feed roller 18. It is supposed to lead to.

The bag-making means 4 cuts the supplied film F into a predetermined length size, and seals one end of the cut film to carry out bag-making.

Specifically, the film F is provided with size marks at regular intervals according to the model number, and the cutting length size is determined by first reading the intervals of the size marks with the mark sensor 19. Next, based on this discrimination, the cutting / sealing means 20 provided in the bag making means 4 is made into the bag making means 4
The cutting and sealing position is moved to a predetermined cutting / sealing position, that is, a cutting / sealing position required depending on the size of the bag to be manufactured, and cutting and sealing are performed.

In this way, a mark indicating the length and size to be cut is attached to each model number, and the cutting and
Since the sealing means 20 is automatically moved to the corresponding position, no manpower is required to adjust the cutting / sealing means 20.

The filling means 5 is for weighing and filling rice into a bag made into a predetermined length size, and after opening the mouth of the bag, a predetermined amount of rice is filled in the bag by the weighing and filling hopper 21. It seals the open mouth.

Finally, the filled and sealed packaged product is discharged onto the conveyor 22 by the discharging means 6 and sent to the delivery area.

The present invention does not relate to the packaging device itself,
Since the present invention relates to a basic packaging system required for designing the packaging device, detailed description of the packaging device based on this packaging system is omitted. Therefore,
If necessary, please refer to other applications filed in connection with this application and Japanese Patent Application No. 62-271794.

Inventory management system for film bobbins This inventory management system for film bobbins is based on the packaging system described above. By using the data exchanged by the control mechanism used in the packaging system, complicated film bobbins can be stored. The inventory management can be managed safely and surely.

Specifically, first, the actual inventory data at an arbitrary time is input to the control mechanism, and thereafter, the consumption data of the film bobbin that is input to the control mechanism according to the operation is sequentially subtracted from the arbitrary inventory data, and the current inventory is then sequentially subtracted. I try to create data. The current-time inventory data obtained there is appropriately grasped online by the film bobbin supplier side, and the required amount is delivered when the current-time inventory falls below a predetermined amount.

The advantage of such a film bobbin inventory management system is that it is possible to always accurately grasp the current inventory without having to count the current inventory, which is very troublesome in high-mix low-volume production. Since the workers can make a delivery schedule in relation to the film bobbin production plan, there is almost no trouble such as out of stock.

<Effects of the Invention> Since the packaging method according to the present invention is as described above, it is possible to greatly improve the efficiency of packaging and sorting of various types of small-quantity production of powdery granules such as rice, and greatly save labor. Moreover, there is an excellent effect that an inventory management system capable of safely and surely managing the inventory of the film bobbins accordingly can be realized.
