Abstract

PURPOSE:To obviate a means for aligning a spout and thereby reduce the manufacturing cost of a device by molding the spout to be attached to a paper container of juice or liquors in the form of a continuous sticker band using resin, and cutting a spout off the continuous sticker band and attaching it to the paper container during a filling step. CONSTITUTION:A multiple sticker band 2 composed of aplurality of spouts 1 continuously connected is formed of resin, and a stack of the continuous sticker bands 2 are supplied to a filling step. Next, during the filling step, each one of the multiple sticker band 2 is taken out in order during the assembly of a paper container using a filling machine, then is positioned and separated by cutting. Further, the spout 1 is introduced through the inner side of a spout attachment orifice in the paper container C, and a flange part 1a is thermally fused to the paper container C. Thus, it is possible to obviate a means for aligning the spout 1 by using the continuous sticker band and at the same time, manufacture the spout itself at a low cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a spout to a paper container for hermetically filling various liquids including beverages such as juice and alcohol.

[0002]

2. Description of the Related Art Conventionally, when attaching a spout to a liquid paper container of this type, the spouts produced one by one are attached to the holes of the paper container by an attachment device attached to the filling device.

[0003]

However, in the conventional mounting method, since the spouts are separately supplied one by one, the mounting device requires the spout aligning means, and therefore the entire device is provided. There is a problem that the cost is high and the manufacturing cost is high. Further, since the spouts are individually formed and manufactured, there is a problem that the spouts themselves are expensive.

The present invention has been made in view of the above problems, and an object of the present invention is to pour a liquid paper container with a spout into a liquid paper container which can reduce the manufacturing cost. It is to provide a method of mounting the outlet.

[0005]

In order to achieve the above object, a method for mounting a spout on a liquid paper container according to the present invention is a resin molding of a multi-stick in which a plurality of spouts are provided side by side. It is characterized in that it is produced by the above method, and the spouts are separated one by one from the multiple sticks and attached to the paper container in the filling step.

[0006]

In the mounting method having the above-described structure, the multiple sticks produced by the molding machine are supplied to the filling machine, and the spouts are individually cut off from the multiple sticks in the filling machine to be mounted on the paper container.

[0007]

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

First, as shown in FIG. 1, for example, a multiple stick 2 having a form in which ten spouts 1 are continuously provided.
Are formed by resin molding. Then, the multiple sticks 2 are supplied to the filling step in a stacked state as shown in FIG. Then, in the filling step, the multiple sticks 2 are taken out one by one during the assembly of the paper container by the filling machine, positioned as shown in FIG. 3, and cut by the cutter 3 to form the spout 1 as shown in FIG. One by one is separated from the end, and as shown in FIG. 5, the spout 1 is inserted from the inside of the spout attachment hole in the paper container C and the flange 1a is heat-sealed to form the paper container C. Install it against. In this case, cutting and mounting are performed while sucking with a sucker from the back side of the spout 1.

Here, in the above-mentioned process, the multiple sticks 2 supplied to the filling process are successively taken out and decreased, so that they must be replenished sequentially. As this means, it may be manually supplied one by one, or, as shown in FIG. 6, a parts feeder 4 or other mechanical method may be used. When the packaging body 5 of the multiple sticks 2 as shown in FIG. 7 which is wrapped in a bundle in an aligned state after molding is used, it is preferable that the packaging is stacked without breaking the alignment. Also, without stacking,
As shown in FIG. 8, the multiple sticks 2 may be supplied one by one to the cutting place by the cutter 3 using a parts feeder 6 and the like.

In addition, after taking out the multiple sticks 2 one by one, positioning is performed to separate the spouts 1 one by one. For this positioning, mechanical operation is performed by a stopper 7 as shown in FIG. In addition to this method, a mark 8 such as a notch is provided for each spout 1 in the multiple stick 2 as shown in FIG. 10, and this mark 8 is detected by an optical sensor 9 as shown in FIG. Arbitrary methods such as a method of positioning by positioning can be adopted.

In the above embodiment, the multiple stick 2 is used.
Although the case where the interval of the spout 1 provided in the same is set to be the same as the width of the spout to be actually attached is shown, for example, as shown in FIG. 12, the interval of the spout 1 is wider than the width of the spout to be actually attached. The multiple stick 2 thus molded may be used. In this case, in order to position and separate the spout 1 in the filling step, as shown in FIG.
The spout 1 should be punched out in the state of being equipped with.

When the spout 1 is attached to the paper container C, the flange portion 1a may be attached to the outside of the spout attachment hole in the paper container C. Further, as the attachment means, for example, an adhesive may be used instead of the heat fusion.

[0013]

As described above, according to the method for attaching a spout to a liquid paper container according to the present invention, a multiple stick having a plurality of spouts arranged side by side is produced by a molding machine, and in the filling step. Since the spouts are detached from the multiple sticks one by one and attached to the paper container, it is possible to omit the spout aligning means which is required when using the individually spouted spouts, and the spouts themselves. Since it can be manufactured at low cost by multiple molding, it is possible to reduce the manufacturing cost of the liquid paper container with a spout.
