Description

  The present invention relates to an aseptic filling apparatus.

  Conventionally, a PET (polyethylene terephthalate) preform is sterilized while being conveyed, the preform is formed into a bottle by a blow molding machine, the bottle is filled with contents such as beverages, and capped to form a sterile package. There has been proposed an aseptic filling method as an in-line system (see, for example, Patent Document 1).

  This conventional aseptic filling method is used when the preform is immersed in the sterilizing liquid, the preform is pulled up from the sterilizing liquid, and then heated air is sprayed on the preform to dry the sterilizing liquid adhering to the preform. The heating with the drying air is intended to prevent the uniform heating of the preform from being impaired and hinder the blow molding. That is, before the preform is heated for blow molding, a sterilizing gas is sprayed onto the preform so that drying of the sterilizing liquid by heated air is omitted, and the preform is suitable for blow molding after sterilization. It is intended to be heated.

  The form for implementing this invention is demonstrated below.

<Embodiment 1>
According to the in-line system in the first embodiment, the aseptic package shown in FIG. 1 is manufactured as a final product.

  As shown in FIG. 1, the aseptic package includes a bottle 2 as a container and a cap 3 as a lid.

  The bottle 2 is made of PET in this embodiment. However, the bottle 2 is not limited to PET, but can be made using other resins such as polypropylene and polyethylene. A male screw 2 b is formed at the mouth 2 a of the bottle 2.

  The cap 3 is formed by injection molding or the like using a resin such as polypropylene, and the female screw 3a is formed simultaneously with the molding of the cap 3.

  The bottle 2 is filled with a sterilized content a such as a beverage in a state where the inside has been previously sterilized. After the contents a are filled, the cap 3 is put on the mouth part 2a of the bottle, and the mouth part 2a of the bottle 2 is sealed by screwing the male and female screws 3a and 2b, thereby completing the aseptic package.

  The bottle 2 is formed as a sterilized container by the following procedure, and is filled into a sterilized package by filling and sealing the contents.

  First, as shown in FIG. 2A, a preform 1 is prepared. This preform is continuously conveyed at a desired speed.

  The preform 1 is formed as a bottomed tubular body having a substantially test tube shape by PET injection molding or the like. The preform 1 is provided with a mouth 2a similar to that in the bottle 2 shown in FIG. A male screw 2 b is formed at the mouth 2 a simultaneously with the molding of the preform 1.

  As shown in FIG. 2B, a heater 19b is arranged in a tunnel shape along the traveling path of the preform 1, and the preform 1 is heated while traveling by the heater 19b. The preform 1 is uniformly heated to about 120 ° C. by this heating.

  The preform 1 is sterilized as shown in FIG. 2C while continuously running after heating. This sterilization treatment is performed by spraying a gas G of hydrogen peroxide, which is a sterilizing agent, from the sterilizing nozzle 6. The sterilizing nozzle 6 is disposed so as to face the mouth 2a and the bottom of the preform 1 respectively.

  The hydrogen peroxide gas G can be generated by, for example, the vaporizer 7 shown in FIG.

  The vaporizer 7 includes a hydrogen peroxide supply unit 8 that is a two-fluid spray that supplies an aqueous solution of hydrogen peroxide that is a sterilizing agent in the form of drops, and a hydrogen peroxide supply unit 8 that supplies hydrogen peroxide. A vaporizing section 9 that vaporizes the spray by heating it to a non-decomposition temperature not lower than its boiling point. The hydrogen peroxide supply unit 8 introduces an aqueous solution of hydrogen peroxide and compressed air from the hydrogen peroxide supply channel 8a and the compressed air supply channel 8b, respectively, and sprays the aqueous solution of hydrogen peroxide into the vaporization unit 9. ing. The vaporizing section 9 is a pipe having a heater 9a sandwiched between inner and outer walls, and the hydrogen peroxide spray blown into the pipe is heated and vaporized. The vaporized hydrogen peroxide gas G is ejected as condensation mist M from the discharge nozzle 9 b to the outside of the vaporizing section 9.

  A conduit 42 through which hot air H flows is connected to the tip of the discharge nozzle 9b. The condensed mist M discharged from the discharge nozzle 9b is mixed with the hot air H and gasified, and the gas G riding on the hot air H is passed through a flexible hose or the like. Flow to the sterilizing nozzle 6.

  The sterilizing nozzle 6 may be installed at a fixed position on the traveling path of the preform 1 or may be moved synchronously with the preform 1.

  The hydrogen peroxide gas G blown from the sterilizing nozzle 6 contacts the surface of the preform 1. Since the preform 1 has already been uniformly heated to a predetermined temperature, the surface of the preform 1 is promptly sterilized without unevenness.

  The preform 1 that has been heated and sterilized is subjected to blow molding as shown in FIG. 2 (D) and formed into a bottle 2 as a container.

  The mold 4 for blow molding is clamped while continuously running at the same speed as the running speed of the preform 1, blow-molded on the preform 1, and opened after molding.

  The mold 4 has a cavity C in the shape of a finished product of the bottle 2 as a container, the mold upper part 4a corresponding to the mouth part 2a of the bottle 2, the mold center part 4b corresponding to the body part of the bottle 2, and the bottle 2 and a mold bottom portion 4c corresponding to the bottom portion.

  Different temperatures are set in the respective parts 4a, 4b, 4c of the mold 4 as required. For example, the mold upper part 4a corresponding to the mouth part 2a of the bottle 2 can be set at a lower temperature than the mold center part 4b and the mold bottom part 4c. Since the mouth 2a of the bottle 2 has already been formed in the preform 1, if the heat is excessively supplied to the mouth 2a, the mouth 2a may be deformed. Therefore, the deformation of the mouth part 2a can be prevented by keeping the temperature of the mold upper part 4a in contact with the mouth part 2a low.

  The preform 1 is mounted in the mold 4 as shown in FIG. 2 (D) after being heated almost uniformly so that its entire temperature rises to a temperature range suitable for molding. Further, the blow nozzle 5 passes through the upper part 4 a of the mold 4 and the mouth part 2 a of the preform 1 and is inserted into the preform 1.

  While the mold 4 is traveling, for example, hot air that is primary blow air or hot air that is secondary blow air is sequentially blown into the preform 1 from the blow nozzle 5 in the cavity C of the mold 4. The preform 1 expands to the final molded product bottle 2.

  When the bottle 2 is molded in the mold 4 as described above, the mold 4 is opened while traveling, and the finished product of the bottle 2 is taken out of the mold 4 as shown in FIG. .

  The bottle 2 continues to run after being taken out from the mold 4 and, as shown in FIG. 3 (F), the contents a such as beverage are filled into the bottle 2 from the filling nozzle 10, and FIG. As shown, it is sealed with a cap 3 which is a lid.

  Thus, the bottles 2 made into a sterile package are collected and transported to the market.

The sterilizing nozzle 6 is located downstream of the heating unit 19a and upstream of the mold 4 (see FIG. 2D). The sterilizing nozzle 6 may be installed at a fixed position on the outer periphery of the wheel 20 or may be rotated around the wheel 20 synchronously with the preform 1.

  A plurality of molds 4 and blow nozzles 5 are arranged around the wheel 21, and turn around the wheel 21 at a constant speed as the wheel 21 rotates.

  As shown in FIG. 2D, the mold 4 includes a mold upper part 4a, a mold center part 4b, and a mold bottom part 4c. When a gripper (not shown) of the wheel 20 receives the preform 1 heated by the heating unit 19 a of the preform feeder 11 and passes it to the mold 4 around the wheel 21, the upper middle and lower parts 4 a, 4 b, 4c unites and holds the preform 1 as shown in FIG. The preform 1 in the mold 4 is formed into a finished product of the bottle 2 by blowing hot air for blow molding from the blow nozzle 5 while turning around the wheel 21 together with the mold 4 and the blow nozzle 5.

  When the preform 1 comes into close contact with the cavity C of the mold 4 and the bottle 2 is formed, the mold 4 is opened when it comes into contact with the wheel 22, and the bottle 2 is transferred to a gripper (not shown) of the wheel 22. . The bottle 2 is conveyed to the filling machine 13 through the wheels 22, 17 and 23.

  The filling machine 13 has a third conveyance path of the bottle conveyance means inside. This third transport path has a row of wheels 27, 34, 35, 36, 37, 38. Along this row of wheels 27, 34, 35, 36, 37, 38, a filler 39 for filling the aseptic bottle 2 with the contents a, and a bottle 3 filled with the contents a with the cap 3 ( A capper 40 for attaching and sealing (see FIG. 1) is provided in order.

  In addition, since the filler 39 and the capper 40 may be the same as a well-known apparatus, description is abbreviate | omitted.

  The aseptic filling apparatus is surrounded by a chamber 41, and the inside of the chamber 41 is divided into an aseptic zone and a gray zone. The preform feeder 11 and the blow molding machine 12 are arranged in the gray zone, and the filling machine 13 is arranged in the aseptic zone.

  Air that has been purified with HEPA is constantly blown into the gray zone, whereby the sterilized bottle 2 is conveyed to the aseptic zone without being contaminated by microorganisms.

  Next, the operation of the aseptic filling apparatus will be described with reference to FIG. 2, FIG. 3 and FIG.

  First, the preform 1 is conveyed to the heating unit 19a by the row of the preform conveyor 14 and the wheels 15, 16, 17, and 18.

  In the heating unit 19a, the preform 1 is uniformly heated to a temperature range suitable for molding while being conveyed by the conveyor 19.

  The preform 1 heated by the heating unit 19a is sterilized by being sprayed with hydrogen peroxide gas G from the sterilizing nozzle 6 as shown in FIG. It is handed over to the mold 4 around. The preform 1 is held by the mold 4 as shown in FIG. 2D, and expands to the finished product of the bottle 2 in the cavity C by blowing hot air for blow molding from the blow nozzle 5.

  The molded bottle 2 is taken out of the mold 4 by the gripper of the wheel 22 after the mold 4 is opened, and the downstream wheels 17, 23, 27, 34, 35, 36, 37, 38 of the wheel 22 are removed. It travels in the filling machine 13 while being transferred to the line.

The bottle 2 filled with the contents a is sealed with the cap 3 applied by the capper 40 (see FIGS. 1 and 3G) and discharged from the outlet of the chamber 41. As described above, since the filler 39 and the capper 40 are known devices, the description of the filling method of the contents into the bottle 2 and the sealing method of the bottle 2 is omitted.

<Embodiment 2>
Also by the in-line system in the second embodiment, an aseptic package similar to the aseptic package shown in FIG. 1 is manufactured as a final product.

  In the second embodiment, the bottle 2 is formed as a sterile container by the following procedure, and is filled with the contents a and sealed to form a sterile package.

  First, as shown in FIG. 6A, a preform 1 similar to that in the first embodiment is prepared. The preform 1 is continuously conveyed at a desired speed.

  As shown in FIG. 6B, the preform 1 is sterilized by spraying hydrogen peroxide gas Ga, which is a sterilizing agent, from the pre-sterilizing nozzle 6a while continuously running. The pre-sterilization nozzle 6a is disposed so as to face the mouth 2a and the bottom of the preform 1 respectively.

  The hydrogen peroxide gas Ga for preliminary sterilization can be generated by the vaporizer 6 (see FIG. 4) used in the first embodiment.

  As shown in FIG. 6C, the preform 1 subjected to the preliminary sterilization treatment is heated while traveling by a heater 19b disposed in a tunnel shape along the traveling path. The preform 1 is uniformly heated to about 120 ° C. by this heating.

  The preform 1 is sterilized as shown in FIG. 6D while continuously running after heating. This sterilization treatment is performed by spraying a gas G of hydrogen peroxide, which is a sterilizing agent, from the sterilizing nozzle 6. The sterilizing nozzle 6 is disposed so as to face the mouth 2a and the bottom of the preform 1 respectively.

  Since the preform 1 is further sterilized by the hydrogen peroxide gas G that is a sterilizing agent in addition to the preliminary sterilization before the heating, the preform 1 is contaminated with microorganisms in the heating step. Can be sterilized again.

  The hydrogen peroxide gas G can be supplied from the same source as the hydrogen peroxide gas Ga for preliminary sterilization, but the flow rate of the hydrogen peroxide gas G can be adjusted according to need. For example, the flow rate of the gas Ga of hydrogen peroxide is doubled.

  The sterilizing nozzle 6 may be installed at a fixed position on the traveling path of the preform 1 or may be moved synchronously with the preform 1 and provided in the same manner as in the first embodiment.

  The hydrogen peroxide gas G blown from the sterilizing nozzle 6 contacts the surface of the preform 1. Since the preform 1 has already been heated to a uniform temperature, the surface of the preform 1 is promptly sterilized without unevenness.

  As shown in FIG. 7E, the preform 1 that has been heated and sterilized is subjected to blow molding and formed into a bottle 2 as a container.

  The mold 4 for blow molding is clamped while continuously running at the same speed as that of the preform 1, blow-molds the preform 1, and opens the mold.

  The mold 4 is configured in the same manner as in the first embodiment, and the temperature of each part 4a, 4b, 4c is similarly set.

  The preform 1 is mounted in the mold 4 as shown in FIG. 7 (E) after being heated almost uniformly so that its entire temperature rises to a temperature range suitable for molding. The blow nozzle 5 is inserted into the preform 1 through the upper part 4 a of the mold and the mouth 2 a of the preform 1.

  While the mold 4 is traveling, primary blow air and secondary blow air are blown into the preform 1 from the blow nozzle 5, so that the preform 1 is the final molded product in the cavity C of the mold 4. It expands to bottle 2.

  When the bottle 2 is molded in the mold 4 as described above, the mold 4 is opened while traveling, and the finished product of the bottle 2 is taken out of the mold 4 as shown in FIG. .

  The bottle 2 continuously runs after being taken out from the mold 4 and, as shown in FIG. 7 (G), the contents a such as beverage are filled from the mouth portion 2a, and as shown in FIG. It is sealed with a cap 3 which is a lid.

  Thus, the bottle 2 made into a sterile package is collected, packaged and transported to the market.

  An aseptic filling apparatus for performing the aseptic filling step is configured as shown in FIG. 8, for example.

  As shown in FIG. 8, this aseptic filling device has substantially the same configuration as that of the first embodiment, but is slightly upstream from the location where the preform conveyor 14 in the preform feeder 11 is connected to the wheel 15. This is different from the first embodiment in that a preliminary sterilization nozzle 6a is additionally provided on the side.

  The preliminary sterilization nozzle 6a has substantially the same configuration as the sterilization nozzle 6. The preliminary sterilization nozzle 6 a may be installed at a fixed position on the outer periphery of the wheel 18, or may be swung around the wheel 18 synchronously with the preform 1.

  Next, the operation of the aseptic filling apparatus will be described with reference to FIGS.

  First, the preform 1 is conveyed to the heating unit 19a by the row of the preform conveyor 14 and the wheels 15, 16, 17, and 18.

  Before the preform 1 enters the wheel 15 from the preform conveyor 14, hydrogen gas Ga is sprayed onto the preform 1 from the pre-sterilization nozzle 6a (see FIG. 6B).

  Preliminarily sterilized preform 1 is heated to a temperature range suitable for molding while being conveyed by conveyor 19 in heating section 19a (see FIG. 6C).

  The preform 1 heated by the heating unit 19a is sprayed with hydrogen peroxide gas G from the sterilizing nozzle 6 as shown in FIG. It is handed over to the mold 4 around.

  In this way, hydrogen peroxide gas Ga is sprayed from the preliminary sterilization nozzle 6a on the upstream side of the heater 19b to the preform 1 before heating and preliminarily sterilized. Since the hydrogen oxide gas G is sprayed, the sterilizing effect of the preform 1 is further improved.

  The preform 1 is held by the mold 4 as shown in FIG. 7E, and is expanded to the finished product of the bottle 2 in the cavity C by blowing hot air from the blow nozzle 5.

  The molded bottle 2 is taken out of the mold 4 by a gripper (not shown) of the wheel 22 after the mold 4 is opened, and the downstream wheels 17, 23, 27, 34, 35, 36, 37, It travels in the filling machine 13 while being transferred to 38 rows.

  In the filling machine 13, the bottle 2 is filled with the sterilized contents a such as a beverage by the filling nozzle 10 of the filler 39 (see FIG. 7G). The bottle 2 filled with the contents a is sealed with the cap 3 applied by the capper 40 (see FIGS. 1 and 7H) and discharged from the outlet of the chamber 41.

  As described above, since the filler 39 and the capper 40 are known devices, the description of the filling method of the contents into the bottle 2 and the sealing method of the bottle 2 is omitted.

  In addition, in this Embodiment 2, the same code | symbol is attached | subjected and shown to the same location as the case of Embodiment 1, and the overlapping description is abbreviate | omitted.

  The present invention can be implemented in various forms without being limited to the above-described embodiments. For example, the molding of the container is not limited to injection blow, and can be molded by various blow molding such as direct blow. Moreover, the conveyance means which conveys a preform and a container is not limited to the wheel conveyance apparatus shown in FIG. Various transport devices that can be transported at a predetermined transport speed in the order in which the containers are formed, for example, a belt transport device, a bucket transport device, and an air transport device can also be used.
