Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a packaging container.

[0002]

2. Description of the Related Art Conventionally, in a packaging container manufacturing apparatus for manufacturing a packaging container containing liquid foods such as milk and soft drinks, a web-like packaging material made of a flexible laminated material is used. Into a tube, and while filling (filling) the liquid food into the tube-shaped packaging material, that is, the packaging material tube, the packaging material tube is sealed at predetermined intervals by a sealing / cutting device and cut to form a prototype container. The brick container is formed by forming and applying a molding process to the prototype container.

[0003] To this end, the sealing and cutting device is provided with a plurality of sealing jaws as sealing means,
The packaging tube is sequentially sandwiched by the sealing jaws, and is sealed in the lateral direction.

[0004]

However, in the above-mentioned conventional manufacturing apparatus, if, for example, an improper adjustment or failure occurs in a specific sealing jaw, the sealing jaw seals the packaging container. Although a defect or the like occurs, the sealing is performed by a plurality of sealing jaws. Therefore, it is identified which sealing jaw is used to seal the packaging container in which the sealing defect or the like has occurred. Can not do.

[0005] In this case, any of the sealing jaws are not properly adjusted,
Not only is it difficult to determine whether a failure or the like has occurred, but also the time during which the operation of the manufacturing apparatus is stopped for the determination becomes longer, which increases the cost of the packaging container.

The present invention solves the above-mentioned problems of the conventional manufacturing apparatus, and is capable of discriminating which sealing means is used to seal the packaging container. The purpose is to provide.

[0007]

For this purpose, in the packaging container manufacturing apparatus of the present invention, a plurality of sealing members are moved as the packaging material tube is conveyed to seal the packaging material tube in the lateral direction. Means, cutting means for cutting a horizontal seal portion of the packaging material tube to form a prototype container, and marking means for marking a different marker for each sealing means.

[0008] In another packaging container manufacturing apparatus of the present invention, there is further provided a forming flap which is moved as the packaging material tube is conveyed, deforms the packaging material tube, and performs preforming. The marking means is provided on the forming flap.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, reference numeral 11 denotes a web-like packaging material made of a flexible laminated material. The packaging material 11 is formed by coating a resin layer made of polyethylene resin or the like on both sides of a paper base material. It has a laminated structure. The packaging material 11
Is manufactured by a packaging material manufacturing machine (not shown), is set on a filling machine in a state of a reel 12, is fed out by a feeding machine 13, and is conveyed in the filling machine.

The packaging material 11 is guided by guides (not shown) provided at several places in the transport direction, and is vertically sealed by a vertical sealing device (not shown) to form a packaging tube 17. While the is transported downward, the liquid food is supplied from above through the filling tube 16 and is filled in the packaging material tube 17. Next, the packaging material tube 17 is sent to a sealing / cutting device (not shown), is sandwiched by sealing jaws as sealing means from both sides in the sealing / cutting device, and is laterally sealed at predetermined intervals. In the meantime, it is deformed by a molding flap (not shown) and preforming is performed. In this case, in the sealing / cutting device, a sealing unit including a plurality of forming flaps and a sealing jaw is used to transport the packaging material tube 17 so that a large number of packaging containers 19 can be manufactured at a high speed. Moved along with
The packaging material tubes 17 are sequentially sandwiched and sealed in the lateral direction.

Subsequently, a horizontally sealed portion of the packaging tube 17, that is, the horizontal sealing portion Sa is cut by a cutting unit (not shown) as cutting means, and a pillow-shaped prototype container 18 is formed. You. Then, each prototype container 18 is formed into a predetermined shape along a fold formed in advance by being subjected to molding processing,
Brick-shaped packaging container 19 containing a certain amount of liquid food
become.

Next, the sealing / cutting device will be described.

FIG. 1 is a perspective view of a flap of a sealing portion according to an embodiment of the present invention, FIG. 3 is a first view showing an operation of a sealing and cutting device according to an embodiment of the present invention, and FIG.

U2 is opposed at the sealing portion P1, is advanced, and is moved downward with the transport of the packaging tube 17, during which the packaging tube 17 is moved by the first and second sealing jaws 47, 49. It is pinched and sealed laterally. For this purpose, a heat seal bar (not shown) as a seal source is provided at the end of the first sealing jaw 47. In this embodiment, a heat seal bar is used as a seal source. However, instead of the heat seal bar, induction heating, high-frequency heating, ultrasonic waves, or the like may be used.

Each of the forming flaps 46, 48 is
It has a base portion 52 and side wall portions 53 and 54 which rise vertically from both sides of the base portion 52, and moves forward (moves to the right in FIGS. 3 and 4 for the forming flap 46 and FIGS. 3 and 4 for the forming flap 48). To the left), guide the packaging material tube 17,
It is deformed by sandwiching it from both sides and preformed. The base 52 includes a bottom wall (not shown) formed integrally with the side walls 53 and 54, and a base plate 55 attached to the bottom wall with screws b1 and b2.

When the sealing in the horizontal direction is performed, the packaging tube 17 is moved downward and sent to the cutting section, and the horizontal sealing section Sa of the packaging tube 17 is cut by a cutting unit (not shown). To that end, the cutting unit is synchronized with the first and second sealing units U1, U2 by driving the drive motor,
And it has the 1st, 2nd cutting jaw moved forward and backward in synchronization with each other.

Then, each of the horizontal seal portions Sa is sandwiched and cut by the first and second cutting jaws to form a prototype container 18 (FIG. 2). Meanwhile, the first and second sealing jaws 47, 49 are moved upward after being retracted.

By the way, each of the forming flaps 46, 48
In the present embodiment, an engraving device 64 as marking means is provided on the inner surface of the base plate 55 in the molding flap 46. The marking device 64 is provided with the forming flaps 46, 48.
Is advanced to deform the packaging material tube 17,
Markers such as different characters and symbols are marked for each of the first and second sealing jaws 47 and 49. In the present embodiment, an engraving 65 (for example, alphabetic characters) as a marker is engraved on the packaging material tube 17. In the present embodiment, the marking device 64 is used as the marking means, but a printing device may be used instead of the marking device 64. In that case, the marker can be printed on the packaging tube 17 by the printing device.

Next, the marking device 64 will be described.
