Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a container inner bag used when transporting granular cargo such as agricultural crops, livestock feed, chemicals, and chemical products, and is particularly applicable to containers. This invention relates to a container inner bag capable of discharging cargo without tilting it downward toward the door side.

[Prior Art] Generally, granular cargoes such as agricultural products, livestock feed, chemicals, and chemical products are usually transported using bulk containers with multiple manholes in the ceiling, but in some cases, bulk containers with multiple manholes in the ceiling are used for transportation. Attempts have been made to transport these granular cargoes using containers.

However, since dry containers handle a wide variety of cargo, there are problems from a sanitary perspective when transporting food cargo, and it also takes a lot of time to clean the inside of the container and dry it afterwards. There's a problem.

Therefore, the present applicant previously proposed, for example, Utility Application No. 59-
In No. 128984, a container inner bag was proposed in which a bag body was installed inside the container and cargo was stowed inside the bag body.

[Problems to be solved by the invention] By the way, in the conventional container inner bag, when discharging the cargo inside the bag body, it is necessary to tilt the container downward toward the door. To do this, large equipment such as dump-up equipment is required, and the work is dangerous because the heavy objects are tilted, and in the case of long containers such as 40-foot containers,
In some cases, the ceiling of the building is too low to be sloped, and in such cases there is a problem in that it is impossible to discharge the cargo.

This idea was created in view of the current situation,
To provide a container inner bag which allows cargo in the bag body to be easily and reliably discharged without tilting the container and which does not involve any danger in the work.

[Means for solving the problem] The present invention is removably installed in a container,
at least a bottom surface covering the bottom wall of the container, a pair of side surfaces covering both side walls, and a front surface covering the front wall;
and a bag body having a door surface that covers the door side; a drawer that is laid on the floor surface of this bag body and transports the granular cargo stacked on the top surface to the door side by pulling the door side end. a sheet; an extra length section is provided at the front end of the drawer sheet, and the door side end of the drawer sheet is pulled out from an opening provided at the lower end of the door surface of the bag body; Further, the bag is characterized in that a leak prevention mechanism is provided at the opening of the door surface to prevent granular cargo stacked inside the bag body from leaking from the opening.

[Function] In the container inner bag according to the present invention, a drawer sheet is laid on the bottom surface of the bag body which is removably installed inside the container, and the granular cargo is stacked on the upper surface of the drawer sheet. An extra length portion is provided at the front end of the drawer sheet, and the door end of the drawer sheet is pulled out from an opening provided at the lower end of the door surface of the bag body. In addition, a leak prevention mechanism is installed at the opening on the door surface to prevent the leakage of granular cargo stored inside the bag body, and this mechanism prevents granular cargo from leaking from the opening. be done. In addition, by cutting the lower part of the door surface of the bag body or opening the opening at the lower end of the door surface and pulling the drawer sheet, the granular cargo stacked inside the bag body is transported together with the drawer sheet. It is discharged outside the container. At this time, a part of the granular cargo on the drawer sheet collapses to the front side of the container and tries to remain in that position, but the collapsed granular cargo is collected by the extra length section,
Almost the entire amount is discharged to the outside of the container by the drawer sheet without remaining inside the bag body.

[Embodiment] A first embodiment of the present invention will be described below with reference to the drawings.

Further, as shown in FIGS. 2 and 3, a reinforcing belt 22 is provided at a position slightly above the reinforcing belt 21 on the door surface portion 9d, and both end portions of this reinforcing belt 22 are connected to each side surface portion 9b. A reinforced belt 2 is placed horizontally on the outer surface of the
1. Further, a reinforcing sheet 23 made of, for example, a plastic net material laminated with a plastic film on one side is provided in a portion of the door surface portion 9d below the reinforcing belt 22, and both end portions of this reinforcing sheet 23 are As shown in FIGS. 2 and 3, it is bent toward each side surface portion 9b. And each of the belts 19, 2
1 and 22 and the reinforcing sheet 23, the load from the cargo stacked inside the interior bag 7 can be sufficiently supported without the need to support the outer surface of the door surface portion 9d with a weir plate.

As shown in FIGS. 2, 3, and 6, the bottom surface portion 9a of the bag body 9 has an end portion on the door 3 side that is extended longer toward the door 3 side than the position of the door surface portion 9d; The tip thereof protrudes to the outside beyond the position of the door 3. On the upper surface of this bottom part 9a,
A slip sheet 24 is attached to reduce the frictional resistance with the pull-out sheet 8 to facilitate the pull-out of the pull-out sheet 8 when pulling the pull-out sheet 8 toward the door 3 to discharge cargo. As this slip sheet 24, for example,
A hard film such as PET or a mesh material knitted from stretched plastic threads may be used, but this slip sheet 24 has an integral structure with the bottom part 9a of the bag body 9, that is, the bottom part 9a is attached to the slip sheet 24.
It may also be used.

The drawer sheet 8 laid on the slip sheet 24 is a thick sheet having a length extending from the front end of the dry container 1 to the door 3 and protruding from the door 3 by a required amount, as shown in FIG. It is composed of a strong seat body 8a and a relatively thin extra length portion 8b connected to the front end of the seat body 8a.
As shown in the figure, the temporary fixing tape 25 is folded back at a predetermined width and stacked vertically, and the end thereof has a V-notch 25a as shown in FIGS. 7 and 9.
It is temporarily fixed to the connecting portion between the bottom surface portion 9a and the front surface portion 9c via. That is, the temporary fixing tape 25 holds the drawer sheet 8 against the door 3 with a force above a certain level.
By pulling it to the side, it is cut from the V-notch 25a, and the connection between the drawer sheet 8 and the bag body 9 is released. Further, the portion of the seat body 8a that is pulled out from the door surface portion 9d is wound and stored on the outside of the door surface portion 9d, as shown in FIG.
It is covered by a portion of the bottom portion 9a that protrudes from the door surface portion 9d, and this portion is fixed to the reinforcing belt 21 with adhesive tape or string 26 or the like. Note that instead of the temporary fixing tape 25, a hook, a weak thread, an H-shaped resin stopper, or the like may be used.

Further, on the upper surface of the front end of the sheet main body 8a and the upper surface of the extra-length portion 8b, there are strips 27 extending in the width direction of the drawer sheet 8 at required intervals, as shown in FIGS. 7 and 11. Multiple books are distributed. This rod material 27 is made of a semi-cylindrical plastic material as shown in FIG.
For example, the drawer sheet 8 can be attached with adhesive tape 28.
is fixed. And with this wood 27,
Both side edges of the drawer sheet 8 come closer to the center and the drawer sheet 8 can be prevented from becoming wrinkled.

Note that the end portion A of the drawer sheet 8 on the door 3 side, which is shown with a mesh pattern in FIG. However, since the drawer sheet 8 itself is made of a slippery material, there is a risk of it slipping between the sheet and the winding shaft. Therefore, in this embodiment, the tip portion A is formed of a non-slip soft resin, or a non-slip soft resin sheet is arranged on the surface of the tip portion A that contacts the winding shaft, and the tip portion A is simply formed. Simply wrapping it around the take-up shaft will prevent it from slipping. In addition, this tip part A
By making the straight winding shaft into a triangular shape as shown by the chain line in FIG. It becomes possible.

Next, the operation of this embodiment will be explained.

In use, first, the inner bag 7 on which the drawer sheet 8 is placed is carried into the dry container 1, and the hook 11 is locked to the upper locking metal fitting 5a, and the stopper metal fitting 20 is locked to the lower locking metal fitting 5b. do.

Next, the pulling belt 13 is passed through the metal fitting 14 and pulled out to the door 3 side, and the upper edge belt 10 is wrapped around the locking metal fitting 6 and secured using the tightening belt 12. Thereby, the inner bag 7 is installed inside the dry container 1. At this time, the top part 9 of the bag body 9
e The middle part is pulled up by the pulling belt 13, and the front and back positions of the top part 9e are curved inwardly through the lifting belts 13 on both sides of the top part 9e, so it can be used in long dimensions like a 40-foot container. Even in the case of a container, the sagging of the top surface portion 9e can be significantly reduced.

Once the inner bag 7 is installed in the dry container 1, the cover 15 is rolled up to open the cargo inlet 16, and the granular cargo is introduced into the bag body 9 through the cargo inlet 16. Then, the granular cargo is stacked on the drawer sheet 8 placed on the bottom surface 9a of the bag body 9. At this time, a tongue piece 18 is provided at the opening 17 at the lower end of the door surface portion 9d, and the cargo is stacked on this tongue piece 18, so that leakage of cargo from the opening 17 can be prevented.

On the other hand, when discharging the granular cargo stacked inside the bag body 9, the adhesive tape or string 26 is removed from the state shown in FIG. Spread it out as shown in
The leading end of the drawn sheet is wound around a winding shaft of a sheet winding machine (not shown).

Next, the lower end portion of the door surface portion 9d of the bag body 9,
For example, cut out the lower part of the reinforcing belt 21 using a cutter or the like. The granular cargo stacked on the side of the door surface 9d inside the bag body 9 can be discharged to the outside of the dry container 1 simply by making this incision.

When the granular cargo is no longer discharged by this cutting alone, a sheet winding machine (not shown) is activated to wind up the pull-out sheet 8. As a result, the drawer sheet 8 slides on the slip sheet 24 and the door 3
The granular cargo that is pulled to the side and stacked on its upper surface is conveyed to the door 3 side and sequentially discharged from the dry container 1.

By the way, when the drawer sheet 8 is pulled toward the door 3 side, most of the granular cargo is conveyed together with the drawer sheet 8 and is sequentially discharged. Due to the tension of the pull-out sheet 8, the cargo tends to collapse and remain on the front side. Therefore, if the drawer sheet 8 has a length only up to the front end of the bottom part 9a, that is, if there is no extra length part 8b, crumbled granular cargo will remain on the bottom part 9a. It turns out.

However, in this embodiment, since the extra length section 8b is provided, the crumbled granular cargo is caught by the extra length section 8b, which is sequentially paid out from the stacked state, and is discharged to the outside of the dry container 1. Therefore, almost the entire amount of granular cargo can be discharged by the pull-out sheet 8. At this time, depending on the stacking condition of the granular cargo, there is a risk that the extra length portion 8b may be pulled out while being stacked vertically, but the end portion of the extra length portion 8b may be temporarily fixed. Since they are fixed to the bag main body 9 side via the tape 25, the stacked extra-length portions 8b are eventually spread flat, and the granular cargo can be reliably captured. Also temporary fixing tape 2
5 is cut off from the V-notch 25a when the drawer sheet 8 is wound up with a sheet winder, so that it does not interfere with the drawing out of the drawer sheet 8.

In this way, the pull-out sheet 8 is pulled out of the bag body 9. At this time, if the granular cargo is stacked unevenly on the pull-out sheet 8, when the pull-out sheet 8 is pulled out, , the edges on both sides may come inward and wrinkle. This trend is
It appears conspicuously at the front end of the drawer sheet 8.

However, in this embodiment, since the wood 27 is arranged on the upper surface of the front end of the sheet main body 8a and the upper surface of the four-length section 8b, the drawer sheet 8 is completely prevented from becoming wrinkled, and the granules are removed. It is possible to reliably discharge bulk cargo.

If the granular cargo is discharged in this way,
After a small amount of granular cargo remaining in the bag body 9 is manually discharged, the inner bag 7 is removed from the dry container 1 and disposed of.

Therefore, the granular cargo can be discharged without tilting the dry container 1 downward toward the door 3 side.

FIG. 12 shows a second embodiment of the present invention.
The auxiliary belt 22 in the first embodiment is arranged along the lower edge of the cargo inlet 16, and the door surface portion 9d is moved from the auxiliary belt 22 position to the first
It is designed to be inclined in the same direction as the embodiment. In other respects, the configuration is the same as that of the first embodiment.

By tilting the door surface portion 9d from a high position, an inner bag 7 suitable for granular cargo having a light specific gravity can be obtained.

That is, when granular cargo is put into the bag body 9, the door surface 9d swells toward the door 3 due to the load. In this case, if the specific gravity is heavy, the height of stacking into the bag body 9 must be reduced due to the weight limit of the dry container 1. If the cargo height is lower, the bulge of the door surface 9d will be limited to the lower end. Therefore, if only the lower end of the door surface 9d is sloped as in the first embodiment, Even if the door surface portion 9d swells, there is no risk of pressing the door 3. On the other hand, in the case of cargo with a light specific gravity, the stacking height inside the bag main body 9 becomes high, so that a bulge occurs from a relatively high position of the door surface portion 9d, and therefore, as in the first embodiment, a bulge occurs from a relatively high position. If only the lower end of the door surface portion 9d is inclined, the door surface portion 9d may swell and press the door 3. However, in this embodiment, the door surface portion 9
Since d is inclined from a high position, there is no risk of pressing the door 3 even if the door surface portion 9d swells.

13 to 16 show a third embodiment of the present invention, in which the door surface portion 9d of the bag body 9 is formed with a vertical surface up to the lower end, and the door surface portion 9d is located at a position below the cargo input port 16. The lower edges of both ends of the reinforcing sheet 23 arranged are connected to the lower edge belts 19 at the lower edge of each side surface so that the reinforcing belt 21 and the auxiliary belt 22 can be omitted, and Leakage prevention members 30 having a generally triangular shape or other shape are provided at both ends of the door surface portion 9d side of the portion pulled out to the third side, respectively, to connect the lower ends of both sides of the door surface portion 9d. A presser member 31 made of a cardboard case for packing the inner bag 7 is arranged on the outer surface side of the lower end of the inner bag 9d, and both ends of the outer surface side of the presser member 31 are locked in the grooves 4 shown in FIG. The door surface portion 9d is held down by a bar (not shown) to prevent the door surface portion 9d from bulging.

As shown in FIGS. 15 and 16, the presser member 31 includes a rectangular cylindrical cardboard case 32 for packing the inner bag 7, and three rectangular tube-shaped cardboard cases 32 that are folded into a rectangular cylindrical shape and stored inside the cardboard case 32. Square tube material 33
, three reinforcing materials 34 that are folded into a chevron shape and stored in each square tube material 33 , and end pressers 35 and 36 that are arranged in pairs at both ends of the cardboard case 32 .
It is composed of the above-mentioned materials 33, 34, 3
In the packed state, 5 and 36 are in an unfolded state or a partially folded unfolded state, and the inner bag 7
It is designed to be housed in a cardboard case 32 together with the paper.

Note that in FIG. 13, reference numerals 37 and 38 refer to the ends of the drawer sheet 8 and the bottom portion 9a, which are fixed to the outer surface of the door surface portion 9d in a folded state. These are connection strings provided on each sheet 23. In other respects, the configuration is the same as that of the first embodiment.

However, the cardboard case 3 for packing the inner bag 7
2 is used to press down the lower end of the door surface portion 9d, the bulge of the door surface portion 9d can be suppressed without inclining the lower end of the door surface portion 9d.

17 to 19 show a fourth embodiment of the present invention, in which the structure of the end of the inner bag 7 on the door 3 side is changed.

That is, both end portions of the reinforcing belt 21 arranged on the outer surface of the door surface portion 9d of the bag body 9 are connected to each side surface portion 9b.
It is arranged diagonally downward along the outer surface of the belt, and its tip is connected to the lower edge belt 19. The end of this lower edge belt 19 on the door 3 side is drawn out long as shown in FIG. 17, and a locking metal fitting ( (not shown).

As shown in FIG. 18, both side edges of the door surface portion 9d below the reinforcing belt 21 are in a free state without being connected to each side surface portion 9b, and the both side edges of this free portion and What is tongue piece 18?
They are connected by a connecting member 40 that is approximately in the shape of a right triangle, and have a bucket-like shape as a whole. As a result, even if the lower end of the door surface portion 9d is in a free state, the load of the granular cargo stacked on the tongue piece 18 prevents the cargo from leaking outside.

At a position above the reinforcing belt 21 of the door surface portion 9d, a fixing belt 41 whose only both ends are fixed to the door surface portion 9d is disposed as shown in FIG. and a connecting string 4 provided on the bottom part 9a as shown in FIG.
2 is adapted to be secured with the drawer sheet 8 folded and its outer surface wrapped with the bottom surface portion 9a.

Further, at the lower end of each side surface portion 9b on the door 3 side, a first
As shown in FIG. 7, presser belts 43 are provided, and both presser belts 43
As shown in the figure, they are interconnected on the outer surface of the folded bottom part 9a, and the free part at the lower end of the door face part 9d can be more completely prevented from being pushed outward by the load from the cargo. ing. In other respects, the configuration is the same as that of the first embodiment.

Since the lower end of the door surface portion 9d is left in a free state, when cutting the door surface portion 9d with a scissor or the like to discharge cargo, the cut can be easily made by starting from the free portion of the door surface portion 9d. This makes the discharge work easier. Further, depending on the type of cargo, the cargo may be ejected simply by opening the free portion at the lower end of the door surface portion 9d, and in this case, the ejection work becomes even easier. Further, although the lower end of the door surface portion 9d is free, since the tongue piece 18 and the connecting member 40 are provided, the free movement is restricted by the load of cargo, and leakage of cargo can be prevented. Further, since the presser belt 43 is disposed on the outer surface side of this portion, it is possible to prevent the belt from expanding due to the load of the cargo.

In addition, in this embodiment, the fixing belt 41 is
The presser belt 43 may be provided intermittently at three locations corresponding to the three connecting strings 42.
It may also be attached on the reinforcing belt 21.

Figures 20 to 23 show a fifth embodiment of the present invention, and show the tongue piece 18 in each of the embodiments.
Instead, a cylindrical member 50 is provided in the opening 17 at the lower end of the door surface portion 9d to serve as a leakage prevention mechanism, and a cover 51 is provided inside the bag body 9 to cover the extra length portion 8b.

That is, as shown in FIGS. 20 and 21, the opening 17 at the lower end of the door surface portion 9d is provided with a bent portion 50a at the lower end of the door surface portion 9d and a band-shaped padding member 50b arranged on the lower surface side of the bottom surface portion 9a. A flat cylindrical member 50 that is connected and protrudes toward the door 3 is provided, and as shown in FIG. By pressing, leakage of cargo from the opening 17 can be prevented. Note that this cylindrical member 50 may be constructed by omitting the backing material 50b and directly connecting both ends of the bent portion 50a in the width direction to the bottom surface portion 9a.

Further, the extra length portions 8b of the drawer sheets 8 disposed inside the bag body 9 are stacked as shown in FIG. 23 in the same manner as in FIG. Unlike in the case above, it is temporarily fixed to the upper end of the front surface portion 9c using, for example, an adhesive tape 52. The end portion of the extra length portion 8b and the extra length portion 8b
A part of the stacked part is covered by a cover 51 that is fixed to the upper end of the front surface part 9c and hangs down, so that the cargo stacked inside the bag main body 9 can be stored in the extra length part 8.
Consideration has been given to prevent it from penetrating into the depths of b. In other respects, the configuration is the same as that of the first embodiment.

By using the cylindrical member 50 that protrudes from the opening 17 toward the door 3, the bottom surface 9a and the drawer sheet 8 can be attached to the door 3 as shown in FIG.
When extended to the side, the cylindrical member 50 is pushed out toward the door 3 by the load of the cargo. Therefore, as shown in FIG. 17, the door surface portion 9d can be easily cut out with a cutter or the like without leaving the lower end portion of the door surface portion 9d free. Moreover, since the cover 51 can prevent the cargo from entering the depths of the extra length portion 8b, the cargo can be discharged more quickly when discharging the cargo, and the amount of cargo remaining in the bag body 9 can be reduced. can.

24 to 26 show a sixth embodiment of the present invention, in which the opening 17 at the lower end of the door surface portion 9d in the fifth embodiment is enlarged to a position directly below the reinforcing belt 21, and the opening 17 is expanded to a position directly below the reinforcing belt 21. The cylindrical member 50 is also made longer and has the functions of both a leak prevention mechanism and a cargo ejection mechanism.

That is, the cylindrical member 50 in this embodiment has a door surface portion 9d as shown in FIGS. 24 to 26.
A bent portion 50a at the lower end, a pair of side portions 50c formed by extending the lower ends of each side portion 9b of the bag body 9 toward the door 3 side, and an extension portion of the bottom portion 9a of the bag body 9 toward the door 3 side. The bottom part 9a is formed into a large rectangular tube shape, and the extension part of the bottom part 9a toward the door 3 is longer than the other parts 50a and 50c. Three connecting cords 42 are provided which are secured to a fixed belt 41. And this cylindrical member 50
By pulling it out to the door 3 side as shown in Figure 4,
It serves as a cargo discharge port and prevents leakage of cargo from the opening 17 by bending it together with the drawer sheet 8 and tying the connecting cord 42 to the fixed belt 41 as shown in FIGS. 25 and 26. It is designed to be a leakage prevention mechanism. In addition,
In other respects, the configuration is the same as that of the first embodiment.

However, since the cylindrical member 50 also serves as a cargo discharge port, there is no need to cut open the door surface portion 9d when discharging the cargo.

27 to 29 show a seventh embodiment of the present invention, in which the extra length portion 8b of the drawer sheet 8 is
It is wound around a winding shaft 60 disposed at the lower end of the front side of the bag body 9, and its end is temporarily fixed to the winding shaft 60 using, for example, adhesive tape.

That is, as shown in FIG. 27, a cylindrical winding shaft 60 is rotatably disposed at the lower end of the front side of the bag main body via an attachment rope 61. As shown in FIG. 28, it is pulled out from the bag body 9 and connected to a stopper 20. An extra-length portion 8b is wound around the winding shaft 60, and its end portion is temporarily fixed.

The upper end of the winding shaft 60 has a front surface portion 9 as shown in FIGS. 27 and 29.
A storage cover 62 fixed to c is provided to prevent cargo from entering the lower surface side of the drawer seat 8. In other respects, the configuration is the same as that of the first embodiment.

Even with this configuration, the same effects as in the first embodiment can be expected.

FIG. 30 shows an eighth embodiment of the present invention.
The winding shaft 60 in the seventh embodiment is provided at the upper end of the front side of the bag body 9, and a guide shaft 63 for guiding the drawer sheet 8 is provided at the lower end of the front side of the bag body 9. It is something. Note that the other points have the same configuration as the first embodiment.

By providing the winding shaft 60 at the upper end of the front side inside the bag body 9, the storage cover 62
can be omitted.

In each of the above embodiments, the sheet main body 8a of the drawer sheet 8 is placed flatly on the slip sheet 24 without a folded portion, but as shown in FIG. For example, the folded portion 70 may be provided in the middle portion of the sheet body 8a. By providing this folded part 70, the cargo is ejected separately into the first half and the second half, and although the ejection time becomes somewhat longer, the pulling force of the drawer sheet 8 required during ejection can be reduced. . In this case, since there is a possibility that the cracks may also occur in the folded portion 70 of the drawer sheet 8, it is preferable to provide the cross member 27 also in the folded portion 70, as shown in FIG. 31. Note that the location of the pull-out sheet 8 is not necessarily constant, as it is affected not only by the presence or absence of the folded portion 70, but also by the type of granular cargo to be discharged, the loading condition, etc. Therefore, the slats 27 may be arranged over the entire area of the drawer sheet 8, if necessary.

In addition, in each of the above embodiments, the reinforcing belt 2
