DESCRIPTION OF THE PREFERRED EMBODIMENTS Continuous mixing apparatus 11 according to the present invention
Is a packing machine 1 for filling a content obtained by mixing a hygroscopic material with water and the like.
0 for filling and packaging.

The filling and packaging machine 10 guides the sheet or film-like material S1 so as to wrap the outside of the guide tube 12 arranged in the vertical direction in order to shape the material S1 in the form of a bag, and forms an edge of the cylindrical material S2. The portions are closed by a vertical sealing means 13 to form a vertical sealing portion V, and the tubular material S2 is sealed at predetermined intervals by a horizontal sealing means 14 to form a horizontal sealing portion H. The contents can be filled between H.

In the filling and packaging machine 10 in the illustrated embodiment, a sheet or film-like roll R is set inside the main body, and a sheet or film-like material S1 drawn therefrom is placed on a guide plate 15 on the upper front of the main body. As a result, it is guided in a reverse manner so as to be wound around the outer circumference of the guide cylinder 12. Thereafter, the material S1 is passed through the guide piece 16 at the edge, and the joined edge is joined by means of a heat sheet or the like to form a tubular material S2, and the tubular material S2 is sandwiched from below the front and rear surfaces under the tubular material S2. After the inside gas is removed by the deaeration plate 18 under the action of the ironing roll pair 17 pressurized as described above, the horizontal sealing means 14 is closed at predetermined intervals by means such as a heel sheet to form a filled package S3. .
Therefore, as these sheet and film materials, those made of heat sealable resin can be used.

When the horizontal sealing is performed at the stage of the tubular material S2, it becomes possible to fill a certain amount of the content with the horizontal sealing portion H as a bottom, and the packaging of the content is completed by the next horizontal sealing. That is, the filling of the contents is performed between the two horizontal seals.

In order to fill the mixture of the hygroscopic material and water between the horizontal seal portions H, a mixing section 20 for mixing the hygroscopic material and water is provided before filling. Therefore, the mixture from the mixing section 20 is supplied as contents into the bag having the seal section H as the bottom.

The mixing section 20 has an overflow section 21 for allowing water to overflow and then to flow out. The overflow section 21 supplies a hygroscopic material to a portion of the overflow section 21 covered with a thick water film. The mixing section 20 may be cup-shaped. However, when water is allowed to flow out of a mere opening in the center or the like, a phenomenon occurs in which a hygroscopic material adheres to the edge of the opening and gradually accumulates to close the opening. Was done. Therefore, in the present invention, in order to prevent adhesion of the hygroscopic material by covering the periphery of the opening with a thick water film, means for providing the overflow portion 21 is provided.

The specific shape or structure of the mixing section 20 and the overflow section 21 is not particularly limited as long as the above conditions are satisfied.
The mixing section 20 in the illustrated embodiment is formed in an inverted conical container shape, and has an inlet 22 for water at the upper inner periphery, an outlet 23 for the mixture at the lower center, and serves as an overflow section 21. And a weir for storing water to form a thick water film.

The mixing vessel 24 has an inverted conical mixing vessel 24, and an inlet 22 for forming a water film by flowing water in a layered manner over substantially the entire inner periphery of the mixing vessel 24 is formed. A pipe 25 serving as the overflow portion 21 is provided at the outlet 23 so as to protrude to a required height. Water supply channel 2 at inlet 22
6 is connected, and the mixture pipe 27 is connected to the outlet 23.

With such a structure, the water film 31 becomes thickest outside the pipe 25, and the thickness of the water film gradually decreases outside the pipe 25. See FIG. Since the mouth end of the pipe 25 overflows, it is always covered with a water flow having a considerable thickness, and the adhesion of the hygroscopic material 32 is prevented.

The supply port 28 for the hygroscopic material is connected to the overflow 21
Of the water film is sprayed toward the thickest part of the water film. In the illustrated embodiment, the hygroscopic material is stored in the upper hopper 29, and is fed to the supply port 28 through the charging mechanism 30 therefrom.

In the mixing section 20 having such a structure, the hygroscopic material and water are mixed at a predetermined ratio to form a mixture, which is supplied from the lower end opening 19 of the mixture pipe 27 into the cylindrical material S2. In the case of a cold insulator, the mixing ratio between the highly hygroscopic polymer and water is, for example, 1: 100. In addition, components other than the hygroscopic material and water can be added as necessary.

The lower end opening 19 of the mixing pipe 27 is located above the pair of ironing rolls 17 which are opened and closed. Therefore, when the contents are supplied to the cylindrical material S2 sealed by the lower seal portion, the deaeration plates 18, 18 approach, pressurize the cylindrical material S2 from both front and rear sides to remove air, and the ironing roll. The pair 17, 17 keeps strongly pressurizing the upper seal portion of the tubular material S2 from both the front and rear sides to bring the front and rear surfaces into close contact. The cylindrical material S2 of a predetermined size is fed, and the horizontal sealing means 1
When the number reaches 4, the upper seal portion is sealed, and the upper seal portion of the completed packed package S3 can be simultaneously cut off by the cutter 33.

[0020]

Since the present invention is constructed and operates as described above, the wall of the mixing section, the outlet, etc. are covered with a thick water film of the overflow section formed in the mixing section, and the adhesion of the hygroscopic material is prevented. As the outlet is not blocked, the water-absorbent material and water are continuously mixed and packed into a cylindrical material, so that even a small package such as a coolant can be easily manufactured. It has the effect of being able to.
