Description

  The present invention relates to an apparatus and method for filling a bag for a flexible bag-in-box with a sheet-like spout and storing the bag in an exterior box.

  Conventionally, a flexible bag made of plastic film that can be folded is used as a container to store beverages such as sake and syrup, or industrial chemicals such as developer, and water resistance, chemical resistance, and gas barrier properties against liquid contents Etc. are held by the plastic film of the inner bag, while a bag-in-box that is configured so that the outer box has the rigidity necessary for transportation and storage is used. The bag-in-box configured in this way is superior to the environment because it can be separated and discarded into an inner bag and an outer box at the time of disposal, compared to conventional glass bottles, metal cans, etc. Since collection is unnecessary, it is useful for labor saving and cost saving and can be folded, so that there are advantages such as easy transportation and storage of empty containers and reduction of distribution costs.

  In such a bag-in-box, a spout is used to pour out a predetermined liquid. One end of the spout is fixed to the opening of the bag, and the opening at the other end is closed with a cap. When using the bag-in-box, the user cuts out the spout outlet formed in the outer box in which the bag is stored, takes out the spout of the inner bag, fits it into the outer box, and uses it.

  A back-in-box manufacturing method includes a flat sheet-like continuous bag with a spout in which a large number of single bags are connected through a perforation (a bag row of a plurality of empty flexible bags) along a predetermined conveyance path. Transport processing, filling processing for filling the contents into the flexible bag at the filling station on the transport path, and cutting by cutting the bag row at the cutting station provided on the downstream side of the filling station. A process and a housing step of housing the flexible bag in the exterior box.

  It is known that a bag-in-box manufacturing apparatus includes a conveyance path that is inclined so that the downstream side descends, and the flexible bag filled with the contents conveys the bag row by a force that moves downstream due to its own weight. (For example, refer to Patent Document 1).

Japanese Patent No. 2738240

However, the bag-in-box manufacturing method by filling using a continuous bag with perforations between the bags has the following problems.
1) The perforation may tear due to the weight of the bag filled with the filling machine, and strength deterioration due to the perforation has been a problem.
2) When the bag film is thinned, the degree of cutting ability due to perforation increases.
3) When the same bag is filled with the same weight and the same weight is filled with the same bag, the capacity is different and the bag swells differently, making it difficult to set the cutting conditions.

The present invention is intended to solve the above-described problems of the prior art, and in the manufacture of back-in boxes, in order to increase the reliability of bags and improve productivity, It is an object of the present invention to provide a manufacturing apparatus and method by filling a bag and storing it in an exterior box.

It is a figure which shows the state which the spout was hold | maintained at the spout holder in the filling position of the filling table part, and the cap removed by the capping mechanism. It is a figure which shows an example of the spout of the bag used with the bag filling storage apparatus of the bag-in-box concerning embodiment of this invention, (a) Top view of a cap, (b) Cross-sectional view of a spout with a cap, c) It is sectional drawing of a spout.

  Hereinafter, modes for carrying out the present invention will be described.

  FIG. 1 is a schematic side view of a bag filling and storing apparatus 1 for a bag-in-box according to an embodiment of the present invention.

  FIG. 5 is a view showing an example of the spout 5 and the cap 6 of the bag 3 used in the bag filling and storing device 1 of the bag-in-box, where (a) a top view of the cap 6 and (b) a cross-sectional view of the spout with the cap. (C) It is sectional drawing of a spout.

  The spout 5 is joined to the bag 3 of the bag-in-box, and the contents C1 are filled through the spout. The spout 5 is fitted with a cap 6 and plugged.

  The cap 6 is attached to the spout 5 so that the protrusion 8 attached to the cap 6 faces the center of the rearmost side (opposite to the traveling direction) of the bag 3.

  The bag filling and storing device 1 of the bag-in-box detects the protrusion of the cap 6 of the spout 5 of the bag 3 in front of the conveying portion that sends the bag 3 along the predetermined conveying path A1 and the filling position PX of the conveying path A1. The direction determining unit 41 for determining the direction of the bag 3, the filling unit for injecting the contents C1 into the bag 3 at the filling position PX of the transport path A1 through the spout 5, and the bag 3 filled with the contents C1 2 and an accommodation mechanism 20 accommodated in the housing 2.

  FIG. 2 is a view showing a state in which the groove of the spout 5 is sandwiched between the conveyance rails 39 in the conveyance unit 25.

  The transport unit 25 includes an empty bag transport unit 30, a direction determining unit peripheral transport unit 40, and a filling table unit 50 in this order from the outlet of the supply unit 29 to the filling position PX. The empty bag transport unit 30 has an empty bag transport unit 30 driving roller 31 in the lower part, supporting the bag 3 and transporting the bag 3 with the transport rail 39 sandwiching the groove of the spout 5 of the bag 3 and determining the direction.
