Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a filling container device for paper containers 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 that production costs can be reduced by performing assembly from raw materials and filling and packaging the assembled container at the same time.

It also has the advantage of being easy to dispose of after use.

In order to preserve the liquid filled in such paper containers for a long period of time, it has been common practice to use coreless packaging. In order to carry out this aseptic filling and packaging, for example,
As shown in Publication No. 02, a carton material is formed 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.

As shown in the above-mentioned publication, by performing the steps after assembling the bottom of the container in a sterile chamber, there will be no influence from the outside. Because of the curly folding process, paper dust is inevitably generated, which contaminates the inside of the sterile chamber.

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, the sterile chamber becomes large and there is a problem in that it is difficult to maintain a constant atmosphere inside the chamber.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a filling and packaging apparatus for filling and packaging paper containers in which the aseptic chamber is made as small as possible and the influence of paper powder is minimized.

Means for Solving the Problems> The present invention provides a bottom forming section for assembling the bottom of a folded container material into a cylindrical shape using a mandrel. a forming section that has a paper dust removal section that performs this process, and a primary curling device that creases the top, and a sterilizer spraying device that is located below the forming section and sterilizes open containers conveyed from the forming section. , a sterile chamber containing a drying device, a filling nozzle, a secondary folding device, an opening heating device, and a sealing device, the inside of which is kept in a positive pressure state from the outside; a transfer device that transfers the container from the molding section to the sterile chamber; Consisting of
In addition, the endless conveying device that conveys the containers in the sterile chamber has cells that fix the containers at regular intervals, and one of the connecting holes that fixes them to the chain is made thicker (and the cell guides are removed from the molding part to remove the containers from the molding part. This is a filling and packaging device for paper containers, characterized in that a receiving part is opened more than other parts.

In the molding section, assembly of the bottom part where paper dust is most likely to occur,
After the top part is first folded and the paper dust is removed, the paper is transferred to the 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 became easier to maintain the inside of the chamber in a sterile state.

Furthermore, since the molding section and part of the sterile chamber are separated from each other in the transport mechanism, even if an abnormality occurs in the molding part, the sterility of the part of the sterile chamber will not be affected. One of the connection holes for the container is fixed to the chain in a larger state, and the cell guide is opened in the part that receives the container from the molding part than in the other part, so that the cell guide in the part that receives the container is larger than the other part. The container is opened along the guide, and the container transferred from above can be smoothly transferred from the molding section into the sterile chamber without hitting the cells.

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

FIG. 1 is a schematic cross-sectional explanatory view showing an example of the filling and packaging apparatus of the paper-made invention of the present invention, in which a supplying apparatus 10 for supplying a cylindrical paper container material, a radial section 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. A molding section A having a powder removing device and a primary curling device 13 for folding the top part along ruled lines, a sterile chamber B having a conveyance device for the molding section A and a separate conveyance device, and the molding section A and the sterile chamber 8. This is a paper container filling and packaging device consisting of a transfer bag 3C provided in between.

Here, the sterile chamber B consists of a sterilizing agent spraying device 20, a drying device 21, a filling nozzle 22, a secondary folding device 23, an opening heating device 24, and a sealing device 25 for sealing the opening, in accordance with the transport direction.

In each of the above-mentioned devices, the operating part is located inside a sterile chamber, and the driving source for operating 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 includes 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 part B, and is located above the transfer guide 30, and When the conveyance of the forming section A stops, the moving arm 31 descends and transfers the container from the forming section A to the sterile chamber B along the transfer guide.

Furthermore, as shown in FIG. 2, the conveying device that transports the containers within the sterile chamber that transfers the containers to the sterile chamber of the molding section is equipped with cells 40 for fixing the containers at regular intervals on an endless chain 41. , one of the connecting holes 42A and 42B fixed to the chain 41 is made thicker (
did.

The container receiver of the guide 43 that regulates the transport direction of the cells has its transfer portion opened more than the other portions.

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 the supply device 10 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 the paper dust generated during the bottom formation is removed by a paper dust removing device 12 having a suction mechanism. Perform primary curl folding by folding the top part along the ruled line. After passing through a pre-process in the molding section and being located at the end of the conveying device, the moving arm descends from above and the container is transferred along the moving guide to a cell of the conveying device that is part of the sterile chamber.

At this time, the cell is in a state where the large connection hole 42B side is open along the guide, and even if there is a slight misalignment with the upper molding part, the container can be smoothly transferred without hitting the cell, and in the next step, the container will be transferred smoothly to the guide. The shape of the container is formed along the line, and other processes are not adversely affected.

A sterilizing agent such as steam is sprayed onto at least the inner surface of the opening of the container transferred to a sterile chamber, and then drying is performed using 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 sterile chamber B is discharged.

<Effects of the Invention> As described above, the present invention allows the bottom assembly and the subsequent folding parts where paper dust is likely to be generated to be performed outside the sterile chamber, and to remove a certain amount before being transferred to a part of the sterile chamber. Since the sterile chamber is then transferred, 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 occupying a large area is provided outside a portion of the sterile chamber, the sterile chamber can be minimized in size, making it easier to maintain a constant atmosphere within the portion of the sterile chamber.

Furthermore, since the molding section is provided above and the sterile chamber is provided below, the installation area of the device is small, and the cells for fixing the container of the conveyance device that transports inside the sterile chamber are placed in the molding section of the container. Since the container was designed to open at the transfer section, it was possible to prevent the container from hitting the cell during transfer and causing the device to stop, allowing for smooth operation.

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 in the molding section is resolved, it can be restarted.
