It is like that. Although the heat seal mold 56a (56b) and the cooling mold 62a (62b) can be driven separately, it is more preferable to drive the heat seal mold 56a (56b) and the cooling mold 62a (62b) integrally. preferable.
In addition, you may make it attach suitably the temperature detection means, temperature control means, etc. which are not shown in figure to the heat-sealing type | molds 56a and 56b and the cooling type | molds 62a and 62b.

A method of manufacturing the packaging container 3 using the filling and packaging machine 1 configured as described above will be described.

As shown in FIG. 1, first, when the film wrapping materials 10a and 10b are supplied to the forming device 20, the pockets 11 and 11 are respectively formed in the film wrapping materials 10a and 10b by the pressing die 22 and the forming die 23 of the forming device 20. Molded (see FIG. 2A). If necessary, the film wrapping materials 10a and 10b are heated and softened before molding. The pocket 11 can also be formed by a vacuum forming method, a pressure forming method, or the like. The supplied film wrapping materials 10a and 10b may be drawn separately from separate original rolls (not shown) or drawn from a single original roll (not shown). You may make it use a thing divided into 2 along a longitudinal direction. Alternatively, the pocket 11 may be formed at a predetermined location on one film packaging material, and folded into two in the width direction so that the fold line is on the bottom, and conveyed as film packaging materials 10a and 10b. .

The film wrapping materials 10 a and 10 b in which the pockets 11 and 11 are formed are conveyed opposite to each other by aligning the positions of the pockets 11 and 11, and sent to the filling unit forming device 30. In the filling part forming apparatus 30, the hot plate mold 32 and the receiving mold 33 are heated to a required temperature (for example, about 150 to 170 ° C.), and the pockets 11 and 11 are held and sandwiched, whereby film packaging material The first sealing surface 16 is formed on 10a and 10b, and at the same time, the bottomed filling portion 13 opened upward is formed (see FIG. 2B). The first seal surface 16 may be formed using an impulse seal method, a high frequency seal method, an ultrasonic seal method, or the like. As shown in FIG. 1, the filling and packaging machine 1 is provided with a cooling device 35 having a cooling die 37, and the film packaging materials 10 a and 10 b heated by the filling portion forming device 30 are the contents. Prior to filling 5, it is cooled to about room temperature.

Next, the film wrapping materials 10 a and 10 b are sent to the filling device 40. Since the upper part of the filling part 13 in the film wrapping materials 10a and 10b has not been sealed yet, the filling part 13 can be filled with the contents 5 using the filling nozzle 42 (see FIG. 2C). At this time, if the upper sides of the film wrapping materials 10a and 10b are separated by a guide piece (not shown), the filling nozzle 42 can be easily inserted.

  The film wrapping materials 10a and 10b in which the filling part 13 is filled with the contents 5 are further sent to the sealing device 50, and the upper part of the filling part 13 is sealed by heat fusion. In the sealing device 50, the heat seal dies 56a and 56b are heated to a required temperature (for example, about 150 to 170 ° C.), and the pockets 11 and 11 (parts of the non-filling portion 14) are accommodated in the recesses 57 and 57, By sandwiching the film wrapping material 10a, 10b between the pressure-bonding portion 58 and the seal receiving portion 59, a second seal surface that is continuous with the first seal surface 16 is provided at the periphery of the non-filling portion 14 above the filling portion 13. 17 is formed (see FIG. 2D). At this time, if the second seal surface 17 is formed so as to overlap the first seal surface 16, the sealing performance is improved.

As described above, the cooling dies 62a and 62b of the sealing device 50 are integrally driven with the heat seal dies 56a and 56b, respectively. However, when the film wrapping materials 10a and 10b are sandwiched by the heat seal dies 56a and 56b, the cooling dies 62a. , 62b are opposed to the film wrapping materials 10a, 10b, and the covering portions 63, 63 are in contact with or close to the filling portion 13 so that the surface of the filling portion 13 is substantially entirely covered. Has been made to get. Then, due to the heat exchange action of the refrigerant 66 passing through the cooling path 65, the filling unit 13 is cooled through the covering units 63 and 63, and the temperature rise of the contents 5 filled in the filling unit 13 is prevented (or It is remarkably relaxed). For example, when cooling water of about 15 to 20 ° C. is used as the refrigerant 66, the temperature of the content 5 filled in the filling unit 13 can be maintained at about 20 to 25 ° C.
Further, in the present embodiment, the cooling path 65 is arranged at predetermined positions in the cooling dies 62a and 62b as shown in FIGS. 3 to 5 (small diameters connected to the inlet 67 and the outlet 68 on the wide vertical path. Since the refrigerant 66 such as water for cooling is made to conduct while being raised from the lower stage to the upper stage, an air accumulation or the like in the cooling path 65 is prevented, and a cooling effect is achieved. Is very high.

Although part of the film wrapping material 10a, 10b (second sealing surface 17 and the like) is heated by the heat sealing molds 56a, 56b of the sealing device 50, the filling and packaging machine 1 is used for cooling as shown in FIG. A cooling device 75 provided with a mold 77 is attached so that the entire film wrapping material 10a, 10b is cooled again to about room temperature.
The film wrapping materials 10a and 10b are sent to the punching device 80, and the packaging container 3 having a predetermined shape is punched as the die roll 82 rotates (see FIG. 2 (e)). The remaining film wrapping material 10a, 10b from which the packaging container 3 has been punched is wound up and discharged as scrap or the like.
In addition, if necessary, a secondary sealing device that performs a secondary sealing process such as a line shape or a dot shape on the first sealing surface 16 or the second sealing surface 17 is appropriately attached to the filling and packaging machine 1 to provide a seal. You may make it raise intensity | strength and a design effect.

According to the filling and packaging machine 1 described above, since the filling part 13 is cooled by the cooling molds 62a and 62b of the sealing device 50, the content 5 filled in the filling part 13 is obtained by the heat seal molds 56a and 56b. Less susceptible to adverse effects associated with high temperatures during heat sealing.

Further, according to the filling and packaging machine 1, the gap portions 69a and 69b having a heat insulating effect are provided between the heat seal dies 56a and 56b and the cooling dies 62a and 62b, and the covering portions 63 and 63 having a predetermined configuration are provided. Since the surface of the filling part 13 can be almost entirely covered, the filling part 13 and the content 5 filled in the filling part 13 can be cooled very efficiently. In addition, since the heat seal mold 56a and the cooling mold 62a, and the heat seal mold 56b and the cooling mold 62b are integrally driven through the base portions 54 and 54, respectively, the heat seal operation of the heat seal molds 56a and 56b is easy. In synchronism with the above, the filling portion 13 and the contents 5 filled in the filling portion 13 can be reliably cooled. The mounting block 71 and / or the mounting block 72 provided between the heat sealing molds 56a and 56b and / or the cooling molds 62a and 62b and the base portions 54 and 54 are changed from the heat sealing molds 56a and 56b to the cooling molds 62a and 62b. If it is provided by a heat insulating member (for example, PEEK resin or the like) that prevents each heat conduction, the cooling effect can be further enhanced. You may make it insert such a heat insulation member in the space | gap part 69a, 69b.

  Moreover, according to the filling and packaging machine 1, since the packaging container 3 is manufactured while transporting the film packaging materials 10a and 10b in the transport direction D in a substantially vertical posture, the content 5 is a liquid or the like. However, it is easy to fill the filling portion 13 without overflowing the specified amount, and the entire machine can be made to have a short and compact configuration.

  The cooling unit 53 may have another configuration as long as it has a cooling unit that cools the filling unit 13 during the thermal fusion by the thermal fusion part 52. For example, instead of the cooling dies 62a and 62b, an injection nozzle (not shown) that injects a refrigerant gas onto the surface of the filling portion 13 in conjunction with the heat seal dies 56a and 56b can be used as the cooling means. On the other hand, when the cooling molds 62a and 62b as described above are used, the structure of the cooling part 53 can be simplified, and the heat fusion operation by the heat fusion part 52 can be performed more easily. A reliable cooling effect can be obtained.

A modification of the above embodiment will be described with reference to FIG. 6 (a) shows a packaging container 103 according to a modified example, and FIGS. 6 (b) and (c) show a sealing device 50 ′ according to the modified example (the same reference numerals are given to the same components as above). )

  As shown in FIG. 6A, the packaging container 103 has a five-packed form in which the individual containers 104 are coupled via the perforation 107. Needless to say, the number of packages can be set arbitrarily. At the lower end of each individual container 104, there is provided a marking portion 106 capable of marking characters, figures, symbols and the like such as product names, expiration dates, and serial numbers. The individual containers 104 may be filled with different filling amounts, drug concentrations, types, and the like of the contents 5.

  Even in this modification, basically the same devices (the forming device 20, the filling portion forming device 30) as described above can be used, but according to the form of the packaging container 103, the size and shape of each device, The number of parts is changed. For example, as shown in FIGS. 6B and 6C, the sealing device 50 ′ includes heat seal dies 56a ′ and 56b ′ and cooling dies 62a ′ and 62b ′, and includes a recess 57, a crimping portion 58, a seal receiver. The part 59, the covering part 63, and the like are provided in a manner corresponding to each individual container 104 of the packaging container 103.

The description of the above embodiment does not limit the present invention, and various modifications and design changes can be made without departing from the spirit of the present invention.

For example, the packaging container 3 (103) can be configured in various forms other than the above. The contents 5 may be a powder, a solid, or the like in addition to a liquid or gel / paste fluid.

  Moreover, in the said embodiment, although the pockets 11 and 11 were shape | molded in both the film wrapping materials 10a and 10b, the packaging container 3 (103) was manufactured, but the pocket 11 only in one film wrapping material 10a or 10b. The present invention can also be applied to molding.

FIG. 7A shows an end view of the film wrapping material 10a, 10b in such a case, and FIG. 7B shows a partial configuration of the sealing device 150 (the same configuration as in the above embodiment). The same reference numerals are attached). The sealing device 150 includes a heat sealing mold 156b and a cooling mold 162b as shown in FIG. 7B instead of the heat sealing mold 56b and the cooling mold 62b (see FIGS. 3 and 5). It is used in combination with the heat seal mold 56a and the cooling mold 62a (see FIGS. 3 and 4). The pocket 11 is formed in the film wrapping material 10a on the heat sealing mold 56a and cooling mold 62a side, but the pocket 11 is not formed in the film wrapping material 10b on the heat sealing mold 156b and cooling mold 162b side. The packaging material 10b is superposed on the film packaging material 10a in a flat shape (see FIG. 7A). Therefore, as shown in FIG. 7B, the heat seal mold 156b is provided with a flat seal receiving portion 159 having no recess, and the covering portion 163 of the cooling mold 162b is flush with the opposing wall surface 64 of the cooling mold 162b. Is formed in a flat shape.

According to such a sealing device 150, even when the pocket 11 is formed only in one film wrapping material 10a, it is possible to achieve the same effect as the above embodiment. When the pockets 11 and 11 are formed in both the film wrapping materials 10a and 10b as in the above-described embodiment, the amount of the content 5 that can be filled with the same consumed wrapping material amount increases, and the filling nozzle 42 fills. The setting of the lead becomes easy.
