Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a granular powder form such as malt that is stacked in the bag body by pulling a drawer sheet arranged in the bag body toward the container door. The present invention relates to a container inner bag for discharging cargo, and more particularly to improvement of a structure for fixing a drawer sheet to a bag body.

[Prior Art] Conventionally, there is known a container inner bag in which a bag body is mounted in a container such as a bulk container or a dry container, and a granular powder cargo such as molk is loaded in the bag body. Therefore, the applicant of the present invention has previously described, for example, Japanese Utility Model Application No. 59-
In No. 128984, a container-internal bag of this type was proposed.

By the way, in this kind of conventional container interior bag,
When discharging the cargo in the bag body, it is necessary to incline the container downwardly toward the door side, but in the case of a long container such as a 40-foot container, it is not easy to incline the container and However, when the ceiling of the building is low, there is a problem that the container cannot be tilted to a required tilt angle.

Therefore, the present applicant has previously proposed, for example, Japanese Utility Model Application No. Sho 62-20019.
No. 7 proposes a container-internal bag in which a drawer sheet is arranged in the bag body and the drawer sheet is pulled toward the door so that the cargo can be discharged without tilting the container.

[Problems to be Solved by the Invention] In a container-internal bag having a drawer sheet, since the bag body and the drawer sheet are separate bodies, the folded bag body is unfolded inside the container. At the time of loading, there is a risk that the drawer sheet will shift from the bottom of the bag body, and at the time of loading the granular powder cargo into the bag body installed in the container, when loading the granular powder cargo. There is a possibility that the drawer sheet may be displaced due to the impact of.

Further, when discharging the granular powder cargo by pulling the drawer sheet toward the door side, if the packing of the granular powder cargo is biased, both side edges of the drawer sheet come inward and become wrinkled, Granular powder cargo may not be discharged completely.

The present invention has been made in view of the current situation, and when a folded bag body is unfolded and mounted in a container, or when a granular powdery cargo is loaded into the bag body, a drawer sheet is used. It is possible to completely prevent the slippage, and even if the loading of the granular powder cargo is uneven, when the drawer sheet is pulled toward the door, both side edges of the drawer sheet come inward and wrinkle. It is intended to provide a container-interior bag that never becomes.

[Means for Solving the Problems] The first invention of the present invention is, as a means for achieving the above-mentioned object, a pair which is detachably mounted in a container and which covers at least the bottom wall of the container and both side walls. Side of the
A bag main body having a front surface portion that covers the front wall and a door surface portion that covers the door side; a granular powder cargo laid on the bottom surface of the bag main body and stacked on the upper surface by pulling the door side And a drawer sheet to be conveyed to the inside of the container inner bag, the front end portion of the drawer sheet is raised along the inner surface of the front surface portion, and the upper end portion thereof is directed toward the center portion in the width direction. A V-shaped V-shaped portion that gradually cuts downward is formed, and upper and lower end portions on both sides of the V-shaped portion are connected to the inner surface of the front surface portion through a fixing means having a connection fixing force weaker than the breaking force of surrounding members. It is characterized in that it is fixed to.

In a second invention of the present invention, as means for achieving the above object, in a container inner bag having a bag body and a drawer sheet similar to those of the first invention, both side edges in the width direction of the drawer sheet are It is characterized in that they are fixed to the inner surface of the bag body at arbitrary intervals through fixing means having a connection fixing force weaker than the breaking force of the surrounding members.

Furthermore, a third aspect of the present invention is, as a means for achieving the above object, a container interior bag including a bag body and a drawer sheet, which are similar to those of the first aspect of the present invention. The end portion of the door surface is extended to the door side from the position of the door surface portion, and at the lower end of the door surface portion, a bent portion that bends toward the door side along the extension portion of the bottom surface portion is provided to form an extended portion of the bottom surface portion. An opening is formed between the drawer side and the door side end of the drawer sheet is drawn out of the bag body through the opening, and both widthwise ends of the drawer part are drawn out of the bent part and the drawer sheet. It is characterized in that it is fixed to the bag body by a string penetrating the part and the extension part of the bottom part.

[Operation] In the container inner bag according to the first invention of the present invention,
The front end of the drawer sheet is erected along the inner surface of the front surface portion, and the upper end thereof is fixed to the inner surface of the front surface portion through the fixing means. For this reason, when the folded bag body is unfolded and loaded into the container, or when the granular powder cargo is loaded into the bag body, the front end of the drawer sheet is separated from the bag body. There is nothing to do. Further, a V-shaped portion is formed at the upper end of the front end of the drawer sheet, and both upper end portions and lower end portions of the V-shaped portion are fixed to the inner surface of the front surface portion via fixing means. For this reason, when the pull-out sheet is pulled to discharge the granular powdery cargo, the fixing means at the lower end of the V-shaped portion is first released, and then the fixing means at both upper ends of the V-shaped portion is released. Therefore, the drawer sheet will not be obliquely drawn out.

In the container inner bag according to the second aspect of the present invention, the widthwise both side edges of the drawer sheet are arranged at arbitrary intervals.
It is fixed to the inner surface of the bag body via the fixing means.
For this reason, the drawer sheet moves on the bottom surface of the bag body when the bag body is unfolded and installed in the container, when the granular powder cargo is loaded into the bag body, or when the container shakes during transportation. There is no slippage. Also, when the drawer sheet is pulled toward the door, both side edges of the drawer sheet do not come close to the inside and become wrinkled. At this time, since both side edges of the drawer sheet in the width direction are fixed at arbitrary intervals by the fixing means, when the drawer sheet is pulled, the fixation is sequentially released from the fixing means near the door. Therefore, the pulling of the drawn sheet is not hindered.

Further, in the container inner bag according to the third aspect of the present invention, the door-side end of the drawer sheet has an opening formed between the bent portion at the lower end of the door surface portion and the extended portion of the bottom surface portion. It is pulled through to the outside of the bag main body, and both widthwise ends of the drawn-out portion are fixed to the bag main body by a string body that penetrates the bent portion, the drawn-out portion of the drawer sheet, and the extension portion of the bottom surface portion. . That is, both widthwise ends of the drawn-out portion of the drawn-out sheet are completely fixed to the bag body unless the cord body is removed. For this reason, when a granular powder cargo is loaded into the bag body, the collision causes the door-side end of the drawer sheet to completely enter the bag body, making it impossible to pull the drawer sheet when the cargo is discharged. There is no defect.

The lower edge belt 17 is then secured to the lower engaging fitting 7. That is, both ends in the width direction of the door 3 side end of the drawer sheet 21 are completely fixed to the bag body 11 by inserting the lower edge belt 17.

Next, the operation of this embodiment will be described.

When the container inner bag 9 is mounted in the dry container 1, first, the bag main body 11 folded with the drawer sheet 21 previously mounted is unfolded and mounted in the dry container 1.

At this time, as shown in FIG. 10, the end portion of the lower edge belt 17 on the door 3 side is in a state of being inserted into the drawer sheet 21 or the like in advance, and both side edges of the drawer sheet 21 in the width direction and V. The shaped portion 24 is fixed in the bag body 11 by each fixing means. Therefore, when the bag body 11 is unfolded, the drawer sheet 21 is not displaced at all.

After the container inner bag 9 is mounted in the dry container 1, the granular powder cargo is loaded into the bag body 11 through the loading port 31. Then, the granular powder cargo is stacked on the drawer sheet 21 arranged on the bottom surface portion 11a.

At this time, due to the impact when the granular powder cargo is loaded, a pushing force acts on the drawer sheet 21 toward the front side, but the widthwise both side edges of the drawer sheet 21 are inside the bag body 11 by the fixing means. And the widthwise ends of the portion of the pull-out sheet 21 that is pulled out from the opening 28 are
As shown in FIG. 10, since it is completely fixed to the bag body 11 by the lower edge belt 17, the end of the drawer sheet 21 on the door 3 side enters the bag body 11 and the drawer sheet 21 is discharged when the cargo is discharged. There is no problem that you can not pull.

On the other hand, when discharging the granular powdery cargo in the bag body 11,
After the ends of the pull-out sheet 21 and the bottom surface portion 11a on the door 3 side are spread as shown in FIG. 2, the end portions of the pull-out sheet 21 are manually put on a winding shaft of an ejector (not shown).
~ Wind 3 rolls. Then, after that, the lower portion of the door surface portion 11d is cut with a cutter or the like, and the portion of the lower edge belt 17 shown in FIG. 10 is cut, and the discharging machine is activated to wind the pull-out sheet 21 on the winding shaft. As a result, the pull-out sheet 21 is pulled toward the door 3, and the granular powdery cargo on the pull-out sheet 21 is conveyed to the door 3 side and discharged to the outside of the dry container 1.

By the way, when the draw-out sheet 21 is pulled, both edges in the width direction of the draw-out sheet 21 tend to wrinkle toward the center side as the draw-out sheet 21 stretches. This tendency is particularly remarkable when the loading condition of the granular powder cargo is uneven. And
If the pull-out sheet 21 is pulled out in this state, a large amount of granular powdery cargo may remain in the bag body 11.

However, in the present embodiment, both widthwise edges of the drawer sheet 21 are fixed to the bag body 11 by the plurality of velvet fasteners 22 and 23 arranged at intervals in the drawer direction. It is possible to effectively prevent both side edges from approaching the center side. The fixing means is unlocked when a certain limit is reached, and the unlocking is sequentially performed with a certain time delay from the one close to the door 3. Therefore, there is no problem that the force required for pulling the drawer sheet 21 becomes extremely large instantaneously.

When the delivery of the cargo by the drawer sheet 21 progresses to some extent, the folded-back portion formed at the front end of the drawer sheet 21 becomes flat, and the V-shaped portion 24 is pulled toward the door 3 side.

By the way, since the V-shaped portion 24 has different fixing positions to the front surface portion 11c between the center portion in the width direction and the both end portions, the central portion is first released and then the both end portions are released. It will be. That is, also with respect to the V-shaped portion 24, similarly to the case of the both side edges in the width direction of the drawer sheet 21 described above, the fixing is released by the central portion of the V-shaped portion 24 near the door 3 (with respect to the length direction of the drawer sheet 21). This is done first, then both ends of the V-shaped portion 24 are made. Therefore, the V-shaped portion 24 remains wide in the width direction while the front surface portion 1
It is possible to discharge a larger amount of powdered and granular cargo to the pull-out sheet 21 by separating it from 1c.

When the discharge of the cargo by the drawer sheet 21 is completed,
A small amount of the granular powdery cargo left in the bag body 11 is discharged manually or, as shown by the solid line in FIG.
a by using a cutter, the other surface portions 11b, 11 of the bag body 11
Separated from c, 11d and 11e, and then bottom surface 11a
Is wound around the take-up shaft of the ejector and pulled by the mechanical force toward the door 3 side. As a result, the granular powdery cargo remaining in the bag body 11 is discharged.

In the above embodiment, the case where the velvet fasteners 22, 23, 25, 26 are used as the fixing means has been described, but a double-sided adhesive tape, a hook, or a thread or tape cut by applying an external force above a certain level,
Further, other fixing means such as a clip may be used.

[Effects of the Invention] As described above, the first invention of the present invention is such that the front end of the drawer seat is raised along the inner surface of the front surface portion and the upper end thereof is fixed to the inner surface of the front surface portion. Therefore, when expanding the bag body and mounting it in the container, or when loading the granular powder cargo into the container,
Furthermore, there is no problem that the front end of the drawer sheet is displaced when the container shakes during transportation. Further, since the fixing means is provided at both upper end portions and lower end portions of the V-shaped portion formed at the end portion of the drawer sheet, when the drawer sheet is pulled toward the door, the end portion of the drawer sheet is It can be separated from the front surface while keeping it wide in the width direction.

Further, according to the second aspect of the present invention, since both side edges of the drawer sheet in the width direction are fixed to the inner surface of the bag body through fixing means at arbitrary intervals, misalignment of the drawer sheet is prevented. In addition to being able to prevent it, when the drawer sheet is pulled toward the door side, it is possible to effectively prevent both side edges in the width direction thereof from approaching the center side and becoming wrinkled.

Further, according to the third aspect of the present invention, since the door-side end of the drawer sheet is pulled out from the bag body through the opening between the bottom surface portion and the door surface portion, handling at the time of cargo discharge is easy. It's easy. Also, since both widthwise ends of this drawer part are fixed to the bag body by a string, the part of the drawer sheet that has been pulled out of the bag body will not enter the bag body due to the impact when cargo is loaded. There is no problem such as being lost.
