Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an aseptic filling machine for a bag-shaped container with a tubular mouth portion that contains a relatively large volume of liquid such as commercial water and oolong tea.

[0002]

[Prior Art]

 As shown in FIG. 6, a filling machine of this type has a filling nozzle 61, a container receiving table 62 arranged below the filling nozzle 61, and a protruding portion between the filling nozzle 61 and the container receiving table 62. It is known to have the mouth locking member 63 arranged in the.

When the container is filled with contents, the larger the head space in the container (the part not occupied by the contents and the remaining air), the more the contents are deteriorated due to the oxidative action. The smaller the headspace, the better.

Conventionally, as a means for reducing the head space, after filling and before capping, the residual air is vacuumed from the mouth part by a vacuum device, and the body part of the container is throttled by a throttling device to discharge the residual air It is known that the residual air is discharged from the container by extruding from the container.

[0005]

[Problems to be solved by the device]

 In the above, it may not be possible to try to exhaust the residual air after filling. The reason is that since the bottom of the container is flat, the filling liquid collides with it and the filling liquid is agitated, which creates air traps at the top of the container during filling (Fig. 6b). This is because if left as it is after filling (FIG. 6c), it is difficult to discharge it through the mouth of the container.

An object of the present invention is to provide a filling machine for a bag-like container with a tubular opening, which can be filled so as to minimize the head space.

[0007]

[Means for Solving the Problems]

 A bag-shaped container filling machine with a tubular mouth according to the present invention is arranged so as to protrude between a filling nozzle, a container receiving table disposed below the filling nozzle, and the filling nozzle and the container receiving table. In a filling machine for a tubular bag with a mouth part, which is provided with a mouth locking member, a pillow for inclining the bottom part of the container is provided on the top surface of the container receiving table. To do.

[0008]

[Action]

 In a filling machine for a bag-shaped container with a cylindrical mouth, a pillow for tilting the bottom of the container is provided on the top of the container receiving table, so that the filling liquid flows along the slope of the bottom of the container. Since the filling liquid is not agitated, air cannot be trapped at the top of the container during filling.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the container 11 includes a soft plastic bag 12 that is folded in a flat shape and a hard plastic cylindrical mouth portion 13 that is provided on the outer periphery of the soft plastic bag 12 so as to be close to a part thereof. And consists of. A flange 14 is provided on the outer surface of the mouth portion 13, and a hard plastic cap 15 is covered above the flange 14.

Also as shown in FIG. 1, the filling machine includes a vertical tubular filling nozzle 21 that can be raised and lowered, a container receiving table 22 that is arranged below the filling nozzle 21 and that can be raised and lowered, and a filling nozzle 21. And a container locking table 23 which is arranged so as to project between the container receiving table 22 and which can be raised and lowered.

The filling nozzle 21, the container receiving table 22 and the mouth locking member 23 can be raised and lowered separately by means not shown.

A pillow 31 is provided on the upper surface of the container receiving table 22. The pillow 31 is formed in a plate shape having a size capable of holding almost a half portion of the container bottom portion including a portion directly below the mouth portion 13. The upper surface of the pillow 31 is formed with an inclined surface 32 which becomes lower toward the center of the container 11, and as a result, the upper surface of the table 22 is inclined so that the portion directly below the nozzle 21 is the highest. Has been.

The locking member 23 is provided with a U-shaped notch 33 into which a portion of the mouth portion 13 below the flange 14 is fitted.

Next, the filling operation will be described with reference to FIG.

Now, as shown in FIG. 2A, the filling nozzle 21 is at the upper limit position, and the table 22 and the locking member 23 are at the lower limit position. In this state, the operator puts the container 11 on the table 22 and the mouth portion 13 thereof is locked by the locking member 23. The distance between the table 22 and the locking member 23 is adjusted in advance to match the size of the container 11. From this state, as shown in FIG. 2 (b), the table 22 and the locking member 23 are simultaneously raised, and when the upper limit is reached, the cap 15 is removed from the container 11. Next, as shown in FIG. 2 (c), when the nozzle 21 descends and its lower end opening is connected to the mouth portion 13, the container 11 is filled in this state. When the filling is completed, as shown in FIG. 2 (d), the nozzle 21 rises and the mouth portion 13 is covered with the cap 15. Finally, when the table 22 and the locking member 23 descend and return to the lower limit thereof, one cycle of the filling operation is completed.

Now, the filling operation will be described in detail with reference to FIG.

FIG. 3A shows a state in which the mouth portion 13 and the nozzle 21 are connected. Although not obvious from the top of the drawing, the container 11 contains some initial inflow air. When the filling liquid is discharged from the nozzle 21, the container 11 is gradually filled with the discharged filling liquid while being expanded. As shown in FIG. 3 (b), as the filling progresses, a downward flow of the filling liquid is generated from the mouth 13 inside the container 11, and the filling liquid collides with the pillow 31 through the bottom of the container. The filling liquid that has collided with the pillow 31 flows along the inclined surface 32 of the pillow 31 toward the side opposite to the mouth portion 13 of the container 11, which causes a unidirectional flow in the container 11, which causes the above-mentioned flow. The initial incoming air is collected in the container 11 near the mouth 13 without being agitated. Then, as shown in FIG. 3 (c), when the filling is completed, the whole container is tilted so that the portion of the mouth portion 13 is raised by the amount of the pillow 31, and the vicinity of the mouth portion 13 is inclined. The collected air is stored near the mouth 13 in a slightly compressed state. Then, when the nozzle 21 rises and the connection between the mouth portion 13 and the nozzle 21 is cut off, air is discharged from the mouth portion 13 and only the minimum amount of air remains in the container 11. A practical example of the filling operation will be described in detail with specific numbers.

The capacity of the container 11 is 10 liters, and the size of the container 11 in the flat state is 400 × 300 mm. The initial incoming air was 150 ml.

The container 11 was filled as described above. In this case, referring to FIG. 3 (c), the distance H from the upper surface of the table 22 to the upper end surface of the mouth portion 13 was 150 mm, and the height h of the pillow 31 was 30 mm. As a result of the filling, the amount of air finally remaining in the container 11 was 80 ml.

When the same container 11 was filled in the same manner without a pillow, the amount of residual air was 150 ml.

As is clear from the above comparison, when the pillow 31 is used, the residual air amount is reduced to almost half, and the effect is great. The height h of the pillow 31 naturally varies depending on the size and shape of the container 11, but for the container 11 the height h of the pillow 31 is preferably about 20 to 50 mm. If the height h is too low, there is no effect, but if it is too high, there is no difference in the effect, and the seating of the container 11 only worsens.

A modified example of the pillow will now be described. Instead of the inclined surface 32 of the pillow 31, a step 42 may be formed on the upper surface of the pillow 41 as shown in FIG.

Further, as shown in FIG. 5, when the mouth portion 13 is provided in the central portion of the container 11, a pyramid-shaped pillow 51 is used, and the top of the pyramid is located directly below the mouth portion 13. Pillows are arranged so that

[0025]

[Effect of the device]

 According to this invention, since the filling liquid does not flow along the inclination of the bottom of the container and the filling liquid is not agitated, air cannot be accumulated at the top of the container during filling, so that the head inside the container cannot be filled. Can be filled to minimize space.
