Description

Detailed Description of the Invention This invention forms a folded filling container, attaches a pouring stopper to the formed filling container, then fills the filling container with liquid, and extends the upper part of the filling container to the expanded diameter. The present invention relates to an automatic liquid filling device that seals and seals an opening.

B. Prior art In recent years, moisture-resistant paper containers have come to be used instead of bottles as containers for filling and selling milk, alcoholic beverages, etc. When using such a filled container, it is difficult to open the filled container and pour out the liquid, so it is desirable to attach a suitable pouring stopper. However, the pouring stopper needs to be sealed to prevent the filled liquid from leaking during transportation, etc. Conventionally, a spout is formed in a part of the filled container, and a wet sheet is placed on the inside of the spout. is pasted and a spout plug is attached to the outside.

As an example of a device for filling the filling container with liquid, there is a device described in the September 1980 issue of Packaging Technology. A container is taken out one by one from a magazine containing many flat-folded containers, formed into a rectangular shape, bent at the bottom, sealed under heat and pressure, and then filled. This is a device that fills a container with liquid from a predetermined prefecture, and after filling, folds and bends the upper end of the container, heats and pressurizes it, and seals the container.

The sealed filled container is then transported to another device, where a water tap is attached.

As mentioned above, conventional equipment can form filling containers, fill liquid,
The device for sealing the filling container and the device for attaching the pouring stopper to the board are separate, requiring a large amount of installation space, and the filling container is sealed from the filling device to the fitting of the pouring stopper. There was a problem in that a conveyance device was required to convey the materials, which increased equipment costs. When using the above-mentioned filling container, it is necessary to break open the sheet material that seals the spout of the filling container, and conventionally, the sheet material is broken through with an inner stopper attached to the spout stopper. There is no such thing. Therefore, the sheet material that has been pierced remains in the filling container, causing problems such as hindering the pouring of liquid and increasing the amount of remaining liquid. It is an object of the present invention to provide an apparatus capable of performing all processing such as forming a filling container, attaching a pouring stopper, filling liquid, and sealing the filling container.

A circle is established. The blow-off nozzle 19) is supported so as to be able to move up and down by appropriate means, and normally waits to rise, and when two filling containers 11) come below, it descends to fill the corresponding filling containers tl). It enters into the Tll, blows in clean air, and exhausts the dirty atmosphere from the exhaust nozzle ←11 (41), creating a clean atmosphere inside the filling container +1) +1). After this, the blowout nozzle (8■ (to)) rises.■ is a cylinder that adjusts the height of the blowout nozzle e191 (2).

The liquid filling mechanism 04) is located at a sufficient distance from the cleaning mechanism (+3), and is connected to the liquid tank (1) which contains a large amount of liquid to be filled, and from the liquid tank (c) to the filling container (+1).
It is equipped with two systems of first and second liquid supply nozzles (b) that supply a predetermined amount of liquid to the tank. For example, when filling a filling container with 1.8 tons of liquid, the first and second liquid supply nozzles are used to fill a filling container with half the amount of liquid, 0.9 tons.
Then, the second liquid supply nozzle (4!) supplies 0.9t of liquid, which is half of the remaining amount.

A sealing mechanism (1) is a second temporary folding machine that temporarily folds the upper part (3) of the filling container t'l'l along the bending line (5), and an eighth temporary folding machine (4η, an eighth heater (b) that heats the joint of the filling container (1) to melt the polyethylene on its inner and outer surfaces; and wS2/eighth heater that seals the joint by pressurizing and welding the joint.

During the conveyance, the filling container 11) is fitted with a pouring stopper. When the mechanism (I2) is below the temporary fixing machine, the temporary fixing machine (B4) operates to cut out the spout stopper (8) and attach it to the spout (7) of the filling container 11 from the inside. and temporarily secure it. Subsequently, in the next step, the flange (9) of the spouting stopper (8) temporarily fixed using an ultrasonic welder is integrally welded to the inner surface of the filling container (1). After this, when the filling container (1) 111 with the pouring stopper (8) attached enters the cover of the cleaning mechanism -, the blowing nozzle (A) enters into the filling container +1+ jl+ and clean air At the same time as blowing in, the exhaust nozzle 141
), the dirty atmosphere inside the filling container 111113 is discharged to create a clean atmosphere inside the filling volume D(1111+).

The filled container 11+ whose inside has been cleaned is further transferred to a transport mechanism (
1φ to the liquid filling mechanism Q4, and first, when it comes below the second temporary press machine ■, the upper part (3
) to the fold line (5) KG.

Next, half the volume of liquid is supplied to the filling container from the first liquid supply nozzle (B) of the liquid filling mechanism Q41, and then the remaining liquid is supplied from the second liquid supply nozzle (4). After that, the upper part (3) is further temporarily folded using the eighth temporary folding machine [η, and the end portions (I6) and (2)] are supplied with half the amount of liquid.
is heated and the polyethylene in this area is welded and sealed under pressure.

The above-mentioned operations are sequentially repeated on the transport mechanism (lO) to attach the pouring stopper (8) to the filling container (liquid), fill the liquid,
Furthermore, the filling container (1) is sealed continuously. The sealed filled container (1) is removed from the transport mechanism and shipped.

In the above embodiment, the atmosphere inside the filling container (1) contaminated in the previous process is replaced with a clean atmosphere by the cleaning mechanism α, which is preferable from a sanitary perspective. By using the liquid filling mechanism α, the inside of the filling container (1) can be sterilized more completely.

E. Effects of the Invention In this invention, since the spouting stopper attachment mechanism is provided between the bottom forming mechanism and the liquid filling mechanism, the spouting stopper can be integrally attached to the filling container in a series of operations. Workability is improved, and the conveyance device provided between the filling device and the pouring tap attachment device, as in the conventional case, is no longer necessary, and the entire device becomes smaller and less expensive. In addition, the spout plug is installed before filling the liquid, and the inside of the filling container is cleaned after this installation, making it sanitary.Moreover, since the spout plug is attached from the inside of the filling container, it is sealed. Improves sex.
