However, in the carrying bag shown in Patent Document 1, in order to close the openable and closable lower end open part, a plurality of opening/closing cord-like bodies are attached to the carrying bag body for closing the bottom opening body that closes the lower end open part. Therefore, the fixing work was troublesome. Further, the carrying bag shown in Patent Document 2 has an opening/closing cord-like body that is closed by folding the lower end open portion of the carrying bag and locks the folded portion with a linking rope-like body that engages a lifting device. At the same time, a closing structure is formed to close the lower end open portion, and the closing structure is structurally complicated and complicated to handle, even though it is intended to reliably close the lower end open portion.

Therefore, this device was devised in view of the above-mentioned conventional circumstances, and it is possible to easily close the lower opening and closing opening of the cylindrical carrying bag body, and moreover, even if the load of the transported items after closing is closed. A transport bag for lifting equipment that can be securely maintained in a closed state and can be moved safely, and can be safely released and opened at the destination, so that the transported item can be quickly discharged from the lower opening and closing opening. is to provide

In order to solve the above-mentioned problems, in this invention, a cylindrical carrying bag body having an upper opening 3 whose upper part is in an open state and a lower opening/closing opening 5 whose lower part is closed so as to be openable and closable. 1, the upper opening 3 of the carrying bag body 1 is provided with a suspension band 4 for suspending the carrying bag body 1 from the lifting equipment C, and the lower opening/closing opening 5 is provided with this lower opening/closing opening. A folding blocking part 6 is provided to fold and block the 5, and the folding blocking part 6 maintains the closed state and is connected to the lifting device C together with the hanging belt 4 in the folded state. 10 is provided.
The closing means 10 can be configured to be detachably connected to the lifting equipment C or the carrying bag body 1 directly or indirectly at one point.
The closing means 10 is an outer side portion of the outer side of the peripheral surface of the carrying bag body 1 on the folding side of the folding closing portion 6 at the lower opening/closing opening 5 , and is located on the side of the folding portion of the folding closing portion 6 . It can be configured by arranging it in the uppermost layer.

The upper opening 3 is provided with a connecting rope-like band 12 of the closing means 10 and a hanging connecting band 15 along the outer surface of the carrying bag body 1 so as to connect the lifting device C. be able to.

In the carrying bag for lifting equipment according to the invention constructed as described above, the lower opening/closing opening 5 of the carrying bag main body 1 formed in a cylindrical shape is closed by the closing means 10, thereby opening the upper opening. A predetermined material to be transported P is put in and stored from 3, and as it is stored, it is lifted by a lifting device C together with a closing means 10 by a suspension belt 4, and at the destination, the closing means 10 is released and the carrying bag body is lifted as it is. 1 is discharged at the destination.
The folded closing portion 6 provided at the lower opening/closing opening 5 of the carrying bag body 1 closes the lower opening/closing opening 5 by folding and overlapping, and indirectly connects the connecting cord-like belt 12 of the closing means 10 provided at the folded closing portion 6. By connecting it to the lifting equipment C at any time, the closed state of the lower opening/closing port 5 is maintained, and the stored state of the transported goods P is maintained without being opened even during transportation and movement by the lifting equipment C.例文帳に追加
In the folding closing portion 6, the closing means 10 is arranged on the uppermost layer of the folded portion of the folding closing portion 6 after being folded, so that the linking cord-like band 12 of the closing means 10 is connected to the lifting equipment C side. When it is closed, the folded parts are overlapped and contained inside the connecting cord-like band 12 to prevent the unexpected release of the folded parts.
After closing the lower opening/closing port 5, the linking cord-like band 12 of the closing means 10 is linked to the hanging linking band 15 arranged along the vertical direction on the upper outer surface of the carrying bag body 1. Even when lifted by the heavy equipment C, the lower side of the carrying bag body 1 is tilted and cannot be lifted, and the weight balance along the vertical direction of the carrying bag body 1 is not disturbed.
In addition, the closing means 10 is detachably connected to the lifting device C at one point, so that the detachment operation can be performed on the side of the carrying bag main body 1 in the state of being lowered on the moving destination surface. Thus, the material to be transported P can be discharged safely and simply and quickly.

Since this device is configured as described above, the lower opening/closing opening 5 of the cylindrical carrying bag body 1 is closed by the closing means 10, the goods P are accommodated from the upper opening 3, and the movement after transportation is carried out. Various goods P can be transported and moved simply, safely and efficiently by opening the lower opening/closing port 5 by releasing the blocking means 10 previously.

That is, in this device, the upper opening 3 of the carrying bag body 1 formed in a cylindrical shape is provided with a hanging belt 4 for suspending the carrying bag body 1 from the lifting equipment C, and the lower opening and closing opening is provided. 5 is provided with a folding blocking portion 6 for folding and blocking the lower opening/closing port 5, and the folding blocking portion 6 is kept closed and connected to the lifting device C together with the hanging band 4 while being folded. This is because the blocking means 10 for allowing the As a result, it is possible to store and hold the transported material P by closing the lower opening/closing port 5, to transport and move the transported material P while maintaining the holding state, and to discharge the transported material P by opening it at the destination.

In addition, the closing means 10 for closing the lower opening/closing opening 5 is the outer peripheral surface of the carrying bag body 1 which is the folding side of the folding closing portion 6 when closed by folding the folding closing portion 6 in the lower opening/closing opening 5. It is arranged on the uppermost layer of the folded portion of the folded closing portion 6, which is the outer side portion on the opposite side to the portion. Therefore, when the connecting cord-like band 12 of the blocking means 10 is connected to the lifting device C, the folded portion is wrapped inside the blocking means 10, and the lower opening/closing opening 5 closed by folding is lifted. It can be safely moved without being opened even during transportation and movement in a state.

The closing means 10 itself consists of a base band 11 fixed to the carrying bag body 1 at the uppermost layer of the folded portion of the folding closing portion 6, and a connecting cord-like band connected to the base band 11 and connected to the lifting equipment C. 12. By providing an auxiliary connecting band 14 or the like connected to the connecting cord-like band 12 from the base band 11, the entire folding part is held down by the connecting cord-like band 12 on the inner side of the folded closed portion 6. The closed state of the lower opening/closing port 5 can be reliably maintained.

The suspension connection belt 15 is arranged along the outer surface of the carrying bag body 1 at the upper opening 3, so that the suspension connection belt 15 can be connected to the connection rope-like belt 12 of the closing means 10 and the lifting equipment. By connecting C, the connecting cord-like belt 12 closing the lower opening/closing opening 5 and extending along the outer surface of the carrying bag body 1 toward the upper opening 3 side can be connected to the lifting equipment C. Moreover, since the lower end of the suspension linking band 15 is positioned on the outer surface of the carrying bag body 1, the linking with the linking cord-like band 12 can be performed on the outer surface of the carrying bag body 1, and the disconnection can be performed. When opening the carrying bag body 1 first, it is safe because the release work can be performed on the side of the carrying bag body 1 itself placed on the discharge surface.

Furthermore, since the closing means 10 is arranged at the side portion of the carrying bag body 1, for example, when closing the opening/closing opening 5, the opening/closing opening 5, which is the bottom portion of the carrying bag body 1, can be tied directly. For example, at the destination, it is necessary to once lift the carrying bag body 1 and release the tying portion below it. Then, since this release operation is performed directly under the carrying bag body 1, the material P may suddenly fall on the release operator when the opening/closing port 5 is opened, which is very dangerous. Moreover, the release itself is often difficult due to the weight of the transported goods P, and moreover, the release becomes almost impossible when the tying parts become entangled. On the other hand, the closing means 10 in this invention is arranged on the side of the carrying bag body 1, and the operation of opening the opening/closing opening 5 by the closing means 10 at the destination is carried out while the bag is lowered at the destination. , the linking portion 13 of the linking rope-like band 12 may be separated from the suspension linking band 15 or the lifting equipment C. Moreover, these operations can be carried out easily and quickly by removing only one connecting portion 13 of the connecting rope-like band 12 in the closing means 10 from the hanging connecting band 15 or the lifting equipment C. Since it can be performed at the side position on the side of the main body 1, the release work can also be performed safely.

It should be noted that the reference numerals added in the sections for the means for solving the above problems and the effects of the device are provided for ease of reference with the parts showing the constituent parts described in the drawings. This invention is not limited to the structures, shapes, etc. indicated by these descriptions, reference numerals, etc. in the drawings.

It is a perspective view at the time of suspension movement which shows one form for implementing this invention. It is a front view of the carrying bag body similarly. It is a rear view of the carrying bag body similarly. FIG. 11 is a perspective view when the lower opening/closing opening is closed when preparations are made to store the transported object. It is a perspective view when similarly discharging|discharging the conveyed goods in a movement destination. It is a cross-sectional view of the same during discharge of the transported material. It is a front view of the carrying bag main body in other embodiment.

Hereinafter, one mode for carrying out this invention will be described with reference to the drawings. Reference numeral 1 shown in the drawings is a carrying bag body, which is made of, for example, a synthetic resin sheet material and has a cylindrical shape with its top and bottom open. formed. The carrying bag body 1 formed in a cylindrical shape has different sizes with different depths (heights) and diameters (widths) corresponding to the amount of movement of various materials P to be transported, such as earth and sand, agricultural products, and the like. It is available in multiple types.

In addition, a suitable number of belt-like reinforcing bands 2 are provided around the carrying bag body 1 along the circumferential direction and the depth direction so as not to be damaged by being swelled by the stored items P to be transported. For example, they are attached in a grid pattern.

The upper end opening of the carrying bag body 1 is an upper open opening 3 which is opened to throw in the items to be transported P, and is appropriately closed during transportation and movement if necessary. At the upper opening 3, a loop-shaped suspension belt 4 for hanging the carrying bag body 1 itself when it is moved by a crane or other lifting equipment C is projected upward from the upper opening 3. Concatenated. The suspension bands 4 are arranged, for example, as a pair symmetrically with respect to the upper opening 3 of the carrying bag body 1, for example.

A lower end opening of the carrying bag body 1 serves as a lower opening/closing port 5 which is opened and closed to store and support the items P stored in the carrying bag body 1 and to discharge them. The lower opening/closing opening 5 itself is formed so as to be foldable so as to close the lower opening/closing opening 5. For example, the lower opening/closing opening 5 is folded into double or triple folds with an appropriate width to form a folded closing portion 6 that closes the lower opening/closing opening 5. ing.

The folded closure part 6 is provided with a closing means 10 for maintaining the closed state of the folded closure part 6 itself at the uppermost layer portion where the folded closure part 6 is folded and overlapped after folding. As shown in FIG. 5, the closing means 10 is used, for example, when preparing to store the goods P, the carrying bag body 1 is flattened and placed on the work surface, and then the lower opening/closing opening 5 is folded. It is arranged at the uppermost layer portion of the folded closing portion 6 when the closing portion 6 is folded. For example, when the flat carrying bag body 1 that does not contain the goods to be transported P is placed on the work surface and the carrying bag body 1 is placed on the work surface, the folding closure when the carrying bag body 1 is folded is folded. The uppermost layer portion of the portion 6 appears as part of the back surface of the carrying bag body 1, and the closing means 10 is arranged on the back surface.

The closing means 10 itself is a base band 11 fixed to the carrying bag body 1 over at least the length of the width of the rear portion of the carrying bag body 1, that is, the length of the width of the uppermost layer portion of the folded portion of the folded closing portion 6. , a connecting cord-like band 12 connected to the base band 11 and having a connecting portion 13 at its upper end, and a suitable number of auxiliary connecting bands 14 connected to the connecting cord-like band 12 from the base band 11. consists of

The base band 11 may be fixed to the entire periphery of the carrying bag body 1 if necessary, and by doing so, the lower opening/closing port 5 can be closed more securely and stably.

The connecting cord-like belt 12 is directly or indirectly connected to the lifting device C when the carrying bag body 1 is moved, and is arranged on the upper part of the carrying bag body 1 as will be described later. The lifting device C is indirectly linked by being linked to the hanging link belt 15 that is attached. When the linking rope-like band 12 is directly linked to the lifting equipment C, the inner side of the attached upper reinforcing band 2A is inserted through the upper opening 3 of the carrying bag body 1. As shown in FIG.

The linking portion 13 of the linking rope-like belt 12 is, for example, an openable and closable hook ring or a loop so that it can be easily linked to or released from the suspension linking belt 15. It is there. In addition, the connecting cord-shaped band 12 is connected indirectly via the hanging connecting band 15 at one point of the connecting portion 13 provided at the upper end thereof, or directly connected to the lifting equipment C. For some reason, linking or disconnecting from it is easy, and can be done safely without any trouble. Although not shown, the linking portion 13 may be engaged with the side portion of the carrying bag body 1, and the term "indirect" in this specification also includes this case.

As shown in FIG. 2, the auxiliary connecting band 14 is located on the left and right sides of the connecting cord-like band 12 with respect to the connecting cord-like band 12 connected to the substantially central portion of the base band 11 and extending in the vertical direction. are connected obliquely to the connecting cord-like band 12 from the base. By doing so, it becomes possible to collect from a plurality of locations in the blocked lower opening/closing opening 5 and link them to the lifting equipment C, reliably maintain the closed state of the lower opening/closing opening 5, and prevent the conveyed goods P from falling off during movement. I am making it possible. This auxiliary connecting band 14 is particularly effective when the carrying bag body 1 is relatively large and has a large diameter.

In this way, the closing means 10 is arranged on the outer side portion of the carrying bag main body 1 on the side opposite to the outer side portion of the peripheral surface of the carrying bag main body 1, which is the folding side of the folding closing portion 6 in the lower opening/closing opening 5. Before being folded, the connecting cord-like band 12 protrudes downward from the lower opening/closing opening 5 (see FIGS. 2 and 3).

The lower opening/closing port 5 of the carrying bag body 1 does not have the same diameter as the upper opening 3 of the carrying bag body 1. can be formed in a narrowed shape (see FIG. 7).

Also, as shown in the drawing, a hanging connecting band 15 for connecting the connecting rope-like band 12 of the closing means 10 to the lifting equipment C is arranged on the upper part of the carrying bag body 1 . The hanging connecting band 15 is arranged along the outer surface of the carrying bag body 1 in the upper part of the carrying bag body 1 along the vertical direction. An insertion portion 7 is provided so that the suspension connecting band 15 is inserted. The suspension connecting band 15 inserted through the insertion portion 7 is slidable or fixed relative to the carrying bag main body 1 along the vertical direction. Although not shown, it may be inserted between the reinforcing band 2 attached to the upper opening of the carrying bag body 1 and the outer peripheral surface of the carrying bag body 1 . In addition, the lower end of the suspension linking band 15 is positioned, for example, at approximately the halfway point in the depth direction of the carrying bag body 1 so that the linking rope-like band 12 can be connected or disconnected on the outer surface of the carrying bag body 1. be.

In this way, the suspension connecting band 15 is arranged along the outer surface of the carrying bag body 1, so that the carrying bag body 1 can be closed through the closing means 10 that closes the lower opening/closing opening 5 of the carrying bag body 1. The carrying bag main body 1 is tilted when hung by a hand, so that the position of the center of gravity along the vertical direction can be maintained without being inverted.

The hanging connecting belt 15 is detachably connected at its upper end to the hook of the lifting device C and at its lower end to the connecting rope-like belt 12 of the closing means 10. For example, the hook can be opened and closed freely. It is ringed or formed in a ring shape. In any case,
It is sufficient that the lifting device C and the connecting cord-like band 12 are firmly interposed and connected without being separated when connected, and can be easily separated when not in use.

Next, an example of the use of this will be described. The closing portion 6 is folded to expose the closing means 10 . Next, the connecting part 13 of the connecting rope-like band 12 of the closing means 10 is connected to the hanging connecting band 15 arranged on the upper part of the carrying bag body 1 . This completes the preparation for the transportation movement work.

Then, with the upper open port 3 opened, the carrying bag body 1 itself is allowed to stand on its own or the like, and earth and sand and other carrying materials P are thrown in and stored. After storage, the suspension band 4 and the suspension linking band 15 are linked to a predetermined lifting device C to lift, transport, and move.

At the moving destination, after unloading as it is, the connecting cord-like band 12 of the blocking means 10 is removed from the hanging connecting band 15, and the preparation for the discharge operation is completed (see FIG. 5). Next, the lifting device C can be lifted as it is, and the lower opening/closing opening 5 is opened by gradually extending the closing closing portion 6 which has been closed by the load of the stored transported article P, and the lower opening is opened. The material to be transported P is automatically discharged from the opening/closing port 5 (see FIG. 6).

After the discharging work is completed, the carrying bag itself is removed from the lifting device C to prepare for the next carrying work.
