[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a manufacturing facility for synthetic resin products, and more particularly, to a manufacturing facility for easily and economically and stably manufacturing a film having cleanliness.
[0002]
[Prior art]
The film having cleanliness is suitably used for food packaging materials, medical pharmaceutical packaging materials, electronic and electrical equipment components and packaging materials. As a means for producing such a film, for example, a blown water cooled inflation film is used. A manufacturing method is adopted.
[0003]
FIG. 7 shows a conventional apparatus for producing a blown water-cooled blown film, in which the forming apparatus A includes at least a synthetic resin extrusion molding machine 1, a die 2, a slow cooling mechanism 3, a water cooling mechanism 4, and a first pinch roll. 5 and a draining pinch roll 6 and the like, a dryer 8 and a winding mechanism 9, and the molten bubble after passing through the slow cooling mechanism 3 is cooled by passing through the water cooling mechanism 4, The roll is wound around the winding mechanism 9.
[0004]
Conventionally, the inflation film manufacturing equipment using the manufacturing apparatus as described above has housed all the constituent equipment in the same room b in the building a.
[0005]
By the way, in the above manufacturing apparatus, in order to obtain a highly clean film, it is necessary to maintain the cleanliness of the equipment portion where the film after being extruded from the die 2 exists. In such a production apparatus, the water cooling mechanism 4, the take-up mechanism 7, and the winding mechanism 9 correspond to parts that require cleanliness, and the extrusion molding machine 1, the die 2, and the slow cooling mechanism 3 correspond to other parts. These become pollutant emission sources.
[0006]
[Problems to be solved by the invention]
As described above, in the structure in which all the components are housed in the same room b, there is only a film contamination problem due to the low molecular weight volatile gas of the molten resin from the extrusion molding machine 1 and the die 2 that generate much dust. In addition, it is necessary to ensure a sufficient height difference between the extrusion molding machine 1 and the take-off mechanism 7, for example, the extrusion molding machine 1 needs to be installed at a position higher than the height, and for this reason, extrusion molding is required. Every time the material is filled into the machine 1, it is necessary to climb up and down at a high place, which imposes severe working conditions.
[0007]
In addition, the high cleanliness by ventilation and air conditioning is not economically suitable because the pollutant emission source is in the room and not only becomes insufficient but also requires excessive energy.
[0008]
As means to achieve cleanliness, clean the film with pure water, clean air, wipe the surface with a clean adhesive roll, sterilize with ultraviolet rays, hydrogen peroxide, electron beam, autoclave, gamma rays, etc. There is a way to get a degree.
[0009]
However, as its drawback, pure water cleaning requires a large amount of pure water, and a filter for removing water stains is short-lived and is not economically suitable. In addition, the clean air cleaning has a problem that the charging property, which is a characteristic of plastic, impairs the cleaning, and the cleaning cannot be performed sufficiently.
[0010]
In addition, wiping with a clean adhesive roll does not provide cleanliness stability, and there is a residue of adhesive on the film surface. Furthermore, sterilization such as ultraviolet rays does not always provide cleanliness due to residual germs. There is a problem.
[0011]
In particular, in recent years, films having high cleanliness have been demanded due to increasing hygiene of food, safety of medical drugs, miniaturization, high precision, and functional enhancement of electronic and electrical equipment.
[0012]
Then, the subject of this invention is providing the manufacturing equipment of the synthetic resin product which can manufacture products, such as a stable highly clean film, restraining air conditioning energy low.
[0013]
[Means for Solving the Problems]
In order to solve the problems as described above, the present invention has a configuration in which a part required for cleanliness and a part separated from each other by partition walls are stored in separate rooms in a molding apparatus for molding a synthetic resin product. Adopted.
[0014]

It is possible to adjust the positive pressure of the room of this room and use the air flow flowing out from this room to the room of the other part to cool the other part.
[0015]
In the above, the part that requires cleanliness is the molded product take-out side of the molding apparatus, and the other part is the raw material supply side for the molding apparatus.
[0016]
Furthermore, the room of the part requiring the above cleanliness should be air-conditioned in consideration of the air cleanliness, or the room of the other part is installed on the upper floor with respect to the room of the part requiring the cleanliness. It can be set as the structure which has. Thus, by separating and storing the molding apparatus in the upper and lower rooms, it is possible to ensure a height difference, for example, an extrusion molding machine can be installed directly on the floor, and material filling work for the extrusion molding machine Efficiency improvement and labor saving.

[0026]
In the illustrated example, the building a1 has a two-story structure, the lower-floor room 12 and the upper-floor room 13 are separated by a slab serving as a partition wall 11, and the part that requires the cleanliness of the molding apparatus A is designated as the lower-floor room 12. In addition, the part which becomes a pollutant discharge source is stored in the room 13 on the upper floor.
[0027]

In this way, when the part on the molded product take-out side that requires cleanliness and the part on the raw material supply side that becomes the pollutant discharge source are separated into separate rooms 12 and 13 and stored, the part that becomes the pollutant discharge source The synthetic resin product is not contaminated by the generated pollutant.
[0031]
The lower-floor room 12 is positively adjusted by supplying pressurized air from the outside, and the upper-floor room 13 is also adjusted to a positive pressure lower than the positive pressure. Due to the positive pressure difference between the two rooms 12 and 13, Contaminants generated in the upper-floor room 13 can be reliably prevented from entering the lower-floor room 12 containing a portion requiring cleanliness, and the synthetic resin film is more reliably contaminated. Can be prevented. Only the lower floor room 12 may be positively adjusted.
[0032]
Also, by keeping at least the lower floor room 12 that houses the take-up mechanism 7 and the take-up mechanism 9 at an air cleanliness in consideration of the cleanliness of the film, only a small amount of air-conditioning energy is required. Film can be manufactured.
[0033]
In the lower floor room 12 and the upper floor room 13 in the building, spare rooms 15 and 16 are installed between the entrance and the passage, respectively, and as shown in FIG. 16 does not open at least two doors 17 and 18 at the same time, and the spare chambers 15 and 16 of the respective rooms 12 and 13 have a positive pressure with respect to the outside when the outdoor door 18 is opened.
