BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for feeding a bag filled with fluid by a bag-in-box filling machine into a cardboard case.

[0002]

2. Description of the Related Art In general, as shown in FIG. 5, a bag-in-box a is a cardboard case b whose upper side is opened and a flexible bag c which is filled with a fluid and has a spout (inlet / outlet port) is vertically provided from above. The bag c is stored in a state in which it is inflated in the case, and the upper part of the cardboard case b is closed. Thus, the distribution mode of the bag-in-box a is one bag to one cardboard case. It is supposed to be stored in. In addition, recently, in order to increase the storage capacity of the bag-in-box, an attempt has been made to store two bags in one cardboard case, and as described above, by the vertical dropping method of the bag, As shown in FIG. 6, it is considered to store the first bag c and then drop the second bag c thereon.

Further, in the case of storage by dropping from the vertical direction, the dimension of the cardboard case in the height direction is approximately doubled, and there is a problem in the strength of the cardboard case and the handling when stacking the bag-in-boxes themselves. Become. Therefore, as a response to the above request, a cardboard case that can support the flat placement of the bag is prepared, and by storing the bag flatly in two steps,
It was possible to reduce the height of the cardboard case itself.

[0004]

By the way, as described above, the bag has been placed flat in two steps and stored in the cardboard case. This storing procedure is first performed manually as shown in FIG. The bag c is laid flat on the cardboard case b, and then the bag c is manually laid on the bag c again so that the bag c is stored in two steps inside the cardboard case b. The work is very time-consuming.

In view of the above-mentioned circumstances, it is an object of the present invention to allow the bag to be dropped into the cardboard case even when the bag is laid flat, and the bag can be laid flat without manual labor. It is intended to be stored in a cardboard case in two steps.

[0006]

The present invention has been made in view of the above-mentioned problems, and is provided so as to be slidable so that a flexible bag filled with a fluid can be slid down and movable in the horizontal direction. The cardboard case is supported so that the open end of the cardboard case faces the roller conveyor and the discharge end of the roller conveyor, the cardboard case is moved down when the bag is dropped into the cardboard case, and the cardboard case is lifted when waiting to receive the bag. (EN) Provided is a cardboard case storage device characterized by comprising a case lifting / lowering support to be moved, thereby solving the above-mentioned problems.

[0007]

In the present invention, the filled bag on the roller conveyor moves to the cardboard case side without receiving frictional resistance and drops toward the cardboard case while maintaining a flat posture to some extent. When the bag is dropped, the case elevating support lowers and the cardboard case placed on it lowers. If the cardboard case is a flat case, the bag will change its shape while the roller conveyor moves. After moving from to the cardboard case, it spreads on the bottom side of the case and is placed flat. Then, by moving the cardboard case upward while waiting for the bag to be received, it becomes possible to further drop the filled bag on the bag which is in the flat state. Even when the second bag is dropped, the case lifting support is lowered so that the second bag is placed on the first bag in a flat state. Also, if a cardboard case for vertically placing the bag is placed on the bag lifting support,
After the bag moves from the roller conveyor to the corrugated cardboard case while changing its shape, the bag is stored in an inflated shape in the case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIGS. In the figure, reference numeral 1 denotes a cardboard case storage device. The cardboard case storage device 1 includes a roller conveyor 2 for moving down a filled bag c sent from a filling machine (not shown), and discharging of the roller conveyor 2. It is composed of a case lifting support 4 which supports the cardboard case b so that the opening of the cardboard case b faces the end 3.

The roller conveyor 2 has a structure in which the supporting means 6 supports the inclined conveyor main body 5 so that the supporting means 6 can move in the horizontal direction, and the filled bag c is in a substantially flat state without receiving frictional resistance. It is provided so as to be kept and go down to the side of the cardboard case b. Further, the corrugated cardboard case lifting support 4 has a structure in which a base plate 7 on which the corrugated cardboard case b is placed is supported by the lifting means 8.
However, as will be described later, it is provided so as to stop at a bag receiving standby position and a descending position which are set according to the storage form of the bag, and to move up and down between them.

1 to 3 show the case where the bag c is stored in two stages in a flat state. In the corrugated cardboard case storage device 1, the case lifting support 4 is placed so that the discharge end 3 of the roller conveyor 2 is positioned inside the corrugated cardboard case b during standby for receiving the first bag c.
Supports the cardboard case b at the first bag receiving standby position (see FIG. 1A). Further, between the side surface d of the corrugated cardboard case b and the discharge end 3, a bag passage interval e according to the bag capacity is provided so that the bag c can pass while being deformed, as will be described later. The position of the corrugated cardboard case b is set so that the tip portion of the sliding down bag c contacts the bottom side corner f of the corrugated cardboard case b, and the bag c slides down the roller conveyor 2 in a substantially flat state. Then, the bag c comes into contact with the bottom corner f of the cardboard case b (see FIG. 1B).

When the bag c is dropped along the roller conveyor 2, the case lift support 4 is provided so as to start descending, and the bag c extending from the roller conveyor 2 to the cardboard case b is deformed. It comes to pass through the passage interval e (see FIG. 2A). Then, the operation of the elevating means 8 lowers the case elevating / lowering support 4 to a predetermined lowered position, and the bag c is separated from the roller conveyor 2 and spreads on the bottom side of the corrugated cardboard case b to be in a flat state (see FIG. 2 (B)). ).

FIG. 3 shows the process of dropping the second piece. As shown in the figure, when receiving the second bag c, the case lifting / lowering support 4 is raised to the second case receiving standby position and supports the open part of the corrugated cardboard case b so as to face the roller conveyor 2. ing.
The second case receiving standby position is set below the first case receiving standby position by the thickness g of the previously stored bag c (see FIG. 3A). When the bag c is slid down by the roller conveyor 2,
Similar to the above-mentioned first bag c, the shape changes so as to come into contact with the corrugated cardboard case b and enter the bag passage interval e (see FIG. 3B). After that, the case lifting support 4 is provided so as to descend to a predetermined lowering position, and the bag c moves from the roller conveyor 2 onto the first bag c through the bag passage interval e while deforming, and When it is separated from 2, it spreads out on the first bag c and becomes flat (see FIG. 3C). In this way, the two bags are placed flat and stored in two stages.

FIG. 4 shows a process of storing one bag in a vertically installed state in a cardboard case for storing vertically.
In this embodiment, when the cardboard case b for vertical storage is in the case receiving standby position, the discharge end 3 of the roller conveyor 2 is smaller than h / 2 from the conveyor insertion side with the bottom dimension of the cardboard case b being h. It is provided so as to be located within the range i. As shown in FIG. 4B, in the same manner as the above-described embodiment, the case elevating support base 4 is reached when the bag c dropped from the roller conveyor 2 spreads at the bottom of the case while contacting the corner f through the bag passage interval e. Is installed so that
Then, the case lifting support 4 is lowered, the bag c is separated from the roller conveyor 2, and the bag c is stored in the case in a swelled state.
