Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic bag supplying apparatus for continuously supplying a flexible continuous inner bag with a plug sealed on all sides to a filling device and separating the filled inner bags one by one. About.

[0002]

2. Description of the Related Art A so-called bag-in-box, in which a flexible inner bag is housed in an outer box having shape-retaining properties, is easy to separate the inner bag from the outer box after use, and has little disposal problem and is recycled. Is attracting attention as a container that can be used.

[0003] There are two methods of manufacturing such containers: a method in which the continuous bags are filled as they are and cut one by one, and a method in which the continuous bags are cut one by one and then filled.

[0004] That is, in the first method, as shown in FIG. 2, a flexible bag with a plug 3 is the contents from the plug 3 into a continuous inner bag 1 connected in a separable manner, for example, by perforations. Liquids are sequentially filled, sealed, and then separated one by one by a cutter or the like 2 while being transported by a roller conveyor 8 inclined downward as a transport device, dropped through a shooter 5 and stored in an outer box 7 to manufacture. Method (single-row supply type).

A second method is as shown in FIG.
For example, a flexible bag with a stopper 3 is used to separate a continuous inner bag 1 connected by a perforation, such as a continuous inner bag 1, one by one with a cutter or the like 2 and then fills the bag with a liquid as a content from the stopper 3 one by one. Then, after sealing, the roller is slid on a roller conveyor 8 inclined downward, conveyed to a shooter 5 by a conveyor 4 composed of a belt conveyor, dropped through the shooter 5 and stored in an outer box 7 (2 rows). Supply type).

[0006]

In the first method, the liquid is filled on the roller conveyor inclined downward and discharged to the shooter. Therefore, the inner bag is moved to the outer box by the falling speed from the roller conveyor. It is difficult to control the position of the plug when stored. Since the content is filled on the roller conveyor inclined downward, the inner bag may be cut off from the perforation due to the weight of the inner bag after the content is filled. In order to prevent this trouble, a complicated control device is required. The filling device body and the transfer device are integrated, and maintenance is difficult. There are problems such as.

[0007] In the second method, since the continuous inner bags connected in a separable manner are separated one by one before filling the contents, the apparatus becomes complicated. The separated inner bag may be clogged during the transportation to the filling device after being separated due to the habit near the perforation. Since the contents are filled one bag at a time, when the contents are dropped from the shooter to the outer box via the conveyor after filling, the posture control of the inner bag becomes difficult, and the bag may be clogged with the shooter. Similar to the first method, the filling device main body and the transfer device are integrated, and maintenance is difficult. There are problems such as.

The present invention has been made in view of the above problems in the bag supply portion of the continuous inner bag in the apparatus for manufacturing a bag-in-box. The transfer is performed on the same plane, and the filling device main body and the transfer device are configured to be detachable, thereby simplifying the device.

[0009]

Means for Solving the Problems A first invention of the present invention is:
An automatic bag supply device for supplying a continuous inner bag, in which a flexible inner bag with a four-sided sealed plug with a spout is separable at a perforation line, to a filling device, and an inner bag supply for conveying the continuous inner bag. Part, a stopper push-up unit that stably supplies the stopper to the filling unit, an inner bag cutting unit that separates the filled inner bag, and an inner bag transport unit that transports the separated inner bag to a subsequent process. An automatic bag feeding apparatus characterized by the following.

[0010] The second invention is the automatic bag supply device according to the first invention, wherein the inner bag transport section comprises a removable conveyor.

As described above, the present apparatus comprises an inner bag supply section for transporting a continuous inner bag, a stopper push-up section for stably supplying a stopper to the filling section, and an inner bag for separating the filled inner bag. A cutting section, an inner bag transport section that transports the separated inner bag to a post-process,
And a compact automatic bag feeding device. Further, since the inner bag transport section is formed of a removable conveyor, the inner bag transport section has a structure that facilitates maintenance.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments. The automatic bag feeding device of the present invention, for example, as shown in FIG.
It has an inner bag supply section 10 composed of two linear guide rods 12 arranged so that a plug is inserted, and a vertically movable flat plate 21 on which the inner bag is placed. Plug push-up unit 20 in which contents can be filled from a filling nozzle 51 provided in the filling unit 50 through a plug.
And a roller conveyor for transporting the inner bag filled with the contents, which can be detached, and an inner bag cutting portion 40 provided near the stopper push-up portion of the inner bag transport portion. The inner bag supply unit 10, the stopper push-up unit 20, and the inner bag transport unit 30 are arranged on the same plane.

Next, the operation of the automatic bag feeding apparatus will be described. The continuous inner bag 1 in which the flexible inner bag with the spout 3 is separable by a perforation line is taken out of the storage container, and is first sent to the inner bag supply unit 10.

The continuous inner bag 1 is transported so that the plug 3 is sandwiched between two guide rods 12. Next, in the next step, one bag of the continuous inner bag 1 moves to the flat plate 21 of the plug push-up unit 20.

The continuous inner bag 1 moved onto the flat plate 21 is transferred to the flat plate 21 while the stopper 3 is held by the filling portion of the filling device.
Is pushed up, the spout 3 is set on the filling nozzle 51,
The contents such as liquid are filled from the spout.

When filling is completed, the plug is closed, sealed and separated from the filling nozzle, and the flat plate 21 descends and returns to the original position.

Next, the continuous inner bag 1 filled with the contents
Moves to the next inner bag transport section 30. The inner bag cut section 40 provided near the stopper push-up section of the inner bag transport section is operated to cut the perforation line of the continuous inner bag, and the continuous inner bag 1 is filled one by one with contents. Separated. The inner bag filled with the contents is put in an outer box to form a bag-in-box.

Here, the inner bag supply section 10 and the stopper push-up section 2
0, since the inner bag transport section 30 is arranged on the same plane, the inner bag does not slip down from the roller conveyor by itself. Further, even if the inner bag falls between the stopper push-up portion and the roller conveyor, the roller conveyor can be easily separated, so that the inner bag can be easily taken out and the maintenance work of the apparatus can be easily performed.

[0019]

As described above, according to the present invention, it is possible to convert a manual supply type bag supply device to an automatic supply type bag supply device, and the capacity is increased. Further, the apparatus has been simplified and the price has been reduced. Furthermore, since the inner bag flows on the same plane, troubles on the device are reduced.
