Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Application for Fruit Products> The present invention relates to a paper container filling and packaging device for filling and packaging liquids such as milk, juice, and alcoholic beverages into paper containers.

<Prior Art> Currently, paper containers are increasingly being used as containers for liquids. By using this paper container,
It has the advantage of reducing production costs by consistently performing assembly from raw materials and filling and packaging the assembled containers.

Moreover, the disposal of the used one also had the advantage of being simple.

In order to preserve the liquid filled in such paper containers for a long period of time, it has been common practice to perform aseptic filling and packaging. In order to carry out this aseptic filling and packaging, for example,
As shown in Publication No. 02, a carton material is made into a cylinder, transported into a sterile chamber, and in the sterile chamber, the bottom of the container is assembled, the container is sterilized with a sterilizing agent, dried, filled with liquid, the top is folded, The top was folded and the container was sealed.

<Arm to be Solved by the Invention> As shown in the above-mentioned publication, by performing the steps after assembling the bottom of the container in a sterile chamber, external influences are eliminated; Since the top part is folded in a curved manner, paper dust is inevitably generated, and the inside of the sterile chamber is contaminated by the paper dust.

Furthermore, there is a possibility that the generated paper powder may adhere to devices in the sterile chamber or enter the container.

Furthermore, since the container bottom assembly device is located inside the sterile chamber, there is a problem in that the sterile chamber becomes large and it is difficult to maintain a constant atmosphere within the chamber.

Furthermore, a disinfectant spraying device for sterilizing the outside of the container is also located inside the sterile chamber, but in order to reliably sterilize the outside of the container inside the sterile chamber, a fairly complex disinfectant spraying device had to be used. .

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a filling and packaging device which can reduce the size of a sterile chamber, reduce the influence of paper dust as much as possible, and fill and package paper containers in which the outside of the container is more reliably sterilized. The purpose is to

<Means for Solving the Problems> The present invention provides a bottom forming section for assembling the bottom using a mandrel using a folded container material in a cylindrical shape. a forming section that has a paper dust removal section that performs this process, and a primary folding device that creases the top, and a sterilizer that is located below the outer forming section and sterilizes the inside of the open container that is transported from the forming section. Contains a spraying device, a drying device, a filling nozzle, a secondary folding device, an opening heating device, and a sealing device,
It consists of a sterile chamber whose inside is kept under a positive pressure state from the outside, and a transfer device that transfers the container from the molding section to the sterile chamber, and the transfer device is equipped with a sterilizer spraying device that sterilizes the outside of the container. We provide filling and packaging equipment for paper containers.

<Function> In the molding section, assembly of the bottom part where paper dust is likely to occur,
After the top is first curled and the paper dust is removed, it is transferred to a sterile chamber, so that the influence of paper dust is reduced in the sterile chamber.

Furthermore, since it became possible to assemble the bottom of the container at a location other than a part of the sterile chamber, the chamber could be made smaller and it was easier to maintain the inside of the chamber in a sterile state.

Furthermore, since the molding section and a portion of the sterile chamber are separated from each other in the transport mechanism, even if an abnormality occurs in the molding section, the sterility of the portion of the sterile chamber will not be affected.

Furthermore, by equipping the transfer device with a disinfectant spraying device that sterilizes the outside of the container, the disinfectant spraying device can be commercialized and sterilization can be performed more reliably.

<Example> Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a schematic cross-sectional explanatory diagram showing an example of the paper container filling and packaging apparatus of the present invention, in which a supply bag WlO for supplying a cylindrical paper container material, a radial line forming the bottom of the supplied material; A bottom forming device (not shown) in which a mandrel is placed, a conveying device that conveys the container with an open top taken out from the bottom forming device, and a paper that removes paper dust that has adhered to the container during conveyance through the conveying device. It has a powder removing device 11 and a primary curling device N12 for folding the top part along the ruled line.A sterile chamber B equipped with a molding section A, a conveyor for the molding section A, and a separate conveyance device, and the molding section A1! : This is a paper container filling and packaging device consisting of a transfer device 1C provided between sterile chambers B and a sterilizing spray device 19 outside the container.

Here, the sterile chamber B includes a container internal sterilizing shoulder spray device 20, a drying device 21, and a filling nozzle 22 according to the conveyance direction.
, a secondary curling device 23, an opening heating IMW 24, and a sealing device 25 for sealing the opening.

In each of the above-mentioned devices, the operating part is located within a sterile chamber, and the actuator, etc. that operates this operating part is located outside the sterile chamber, and this sterile chamber is always maintained at a more positive pressure than the outside air. , a condition is maintained where outside air does not enter.

Further, the transfer device C is located above a transfer guide 30 having an opening of the same size as the transfer carrier between the terminal end of the molding section A and the start end of the sterile chamber section B, and is positioned above the transfer guide 30. When the conveyance of the molding section A is stopped, the movable arm 31 descends and transfers the container from the molding section A to the sterile chamber B along the transfer guide.

This transfer port is equipped with a sterilizing agent spraying device W19 for sterilizing the outside of the container, and when the container passes therethrough, it is reliably sterilized and transferred to the sterile chamber B.

As the disinfectant spraying device 19, one in which four pipes 40 are arranged in a square shape as shown in FIG. 2 can be used. 4
A large number of spray holes 41 are provided in the inner direction of the square shape of the pipe, and steam is supplied inside from a steam supply pipe 42.

Next, a filling and packaging method using the above-mentioned filling and packaging apparatus will be explained.

First, a cylindrical material for a paper container is inserted into a cylindrical shape from a supply device flo into a mandrel of a bottom forming section, and an assembled bottom is formed by heat sealing.

Next, the container discharged from the mandrel is blown with sterile air by a conveying device having a carrier, and paper dust generated during bottom formation is removed by a paper dust removing device 11 having a suction mechanism. Perform a primary curl fold by folding the top part along the ruled line.

After passing through the pre-process in the molding section, it is located at the end of the conveying device.
A moving arm descends from above, and the container is transferred along a transfer guide to a cell of a transfer device that is part of the sterile chamber.

At this time, a sterilizer such as steam is sprayed from a sterilizer sprayer N19 outside the container.

A disinfectant spraying device 1120 sprays a disinfectant such as steam onto the inner surface of the container transferred to the sterilized soba noodles, and then the container is dried with hot air.

After filling the sterilized container with a predetermined amount of contents from the filling nozzle, it is folded again, and then the inner and outer surfaces of the opening are made bondable with hot air, the top is sealed with a sealing device, and the container is filled. The packaging is completed and the aseptic chamber B is discharged.

<Effects of the Invention> As described above, the present invention allows the bottom assembly and primary folding parts where paper dust is likely to be generated to be carried out outside the sterile chamber, and to remove a certain amount before being transferred to a part of the sterile chamber. Since the paper is transferred later, it is possible to prevent staining of a part of the sterile chamber with paper dust as much as possible.

In addition, since the bottom assembly section, which occupies a large area, is installed outside a part of the sterile chamber, the size of the sterile chamber can be minimized, making it easier to maintain a constant atmosphere inside the part of the sterile chamber. .

Furthermore, since the molding section is provided above and the sterile chamber is provided below, the installation area of the apparatus is reduced.

Furthermore, by equipping the transfer device with a disinfectant spraying device that sterilizes the outside of the container, the disinfectant spraying device can be made uniform and sterilization can be performed more reliably.

Furthermore, since the transport mechanisms for the molding section and the sterile chamber are separate, even if an accident occurs in the molding section, where accidents are likely to occur due to poor molding, the sterility of the sterile chamber will not be compromised.
If the accident at the molding section is resolved, the machine can be operated again.
