Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sterilization device used to sterilize packaging materials.

[Prior Art] Conventionally, in an apparatus for sterilizing packaging materials and filling and sealing them, for example, as seen in Japanese Patent Laid-Open No. 49-4482 and Japanese Patent Laid-Open No. 55-64028, packaging materials are sterilized in a sterilizing bath. Sterilization is performed by passing through the water. By the way, when sterilizing packaging materials in a sterilization bath, raising the temperature of the sterilizing agent is much more effective than sterilizing at room temperature, but heating increases the amount of evaporation of the sterilizing agent that cannot be ignored. becomes. An example of our equipment is as follows.

Chemical: Hydrogen peroxide Heating temperature: 55-60℃ Sterilization bath volume: 400 Evaporation amount: Approximately 10/8 hour operation The present invention aims to provide a packaging material sterilization device that can improve the sterilization effect by heating and prevent the evaporation of chemicals.

[Means for Solving the Problems] The present invention provides a sterilizing agent warmer in a sterilizing bath for packaging materials, and a float having a gap for entering and exiting the packaging material on the surface of the sterilizing agent is placed on the surface of the sterilizing bath. A guide roll is provided which floats over the container and guides the packaging material to pass through the drug through the gap.

[Example] Fig. 1 is a sectional view showing an embodiment of the present invention, and Fig. 2 is a sectional view similar to Fig. 1 showing a conventional device. The packaging material 1, which is a plastic sheet, is sterilized by passing through a sterilizing agent 3 contained in a sterilizing bath 2, and then led to a drying chamber 4 and dried to obtain a sterile packaging material. Ta. Note that numerals 5, 6a, 6b, and 7 are guide rolls for the packaging material.

In the present invention, in addition to this, a warmer 8 for the sterilizing agent is provided to increase the sterilizing effect, and a float 9 is provided to cover the surface of the agent 3 in the sterilizing bath 2 to prevent evaporation of the agent. It is something. Note that the guide rolls 6a and 6b are
The packaging material 1 is passed through the gaps 10 and 10 between the floats.
It is arranged to guide you. In addition, in the figure, the code|symbol 11 is a drying nozzle.

The packaging material sterilizer according to the present invention is constructed as described above, and the temperature of the sterilizing agent 3 is raised by the heater 8, but most of the surface of the sterilizing agent is heated by the float 9.
Since it is covered with a sterilizing bath, it is possible to prevent the evaporation of the medicine and also to prevent heat from escaping from the sterilizing bath.

[Effects] According to the present invention, since the sterilizing agent is heated and used, the sterilizing effect can be dramatically increased, and the evaporation of the agent from the sterilizing bath due to heating is prevented. It can improve the sterilization effect, reduce the consumption of sterilizing chemicals, and save the amount of heating heat.
Furthermore, in the past, when a sterilizing agent such as hydrogen peroxide evaporated, it was necessary to install a removal device to prevent it from leaking outside the device, but in the device of the present invention, the float almost completely covers the surface of the sterilizing bath. Since it is covered, evaporation of the sterilizing agent can be almost prevented, which is highly effective.
