[Industrial applications]

 The present invention relates to a support device for a container, and more specifically, a support device for supporting an opening portion when a powdery material such as feed or a granular material such as resin is placed in a box-shaped container having an opening at one end and transported. Regarding the device.

[0002]

[Prior Art]

 Conventionally, large box-shaped containers have been used to transport various cargoes by truck or ship. In the transportation of cargo by such containers, handling of so-called bulk cargo such as powder and granules has recently been increasing. In this case, set an inner bag (for example, a polyethylene inner bag or a cloth inner bag) as large as the internal volume of the container in the box container (fix it to the four corners of the box container by suitable means such as ropes). This is to fill the granules from the contents supply port of the inner bag and discharge the contents from the contents discharge port of the inner bag after transportation.

In this transportation device, when the contents of the inner bag are discharged, the entire container is tilted at 30 ° to 40 ° so that the opening end of the container faces downward, and the container is installed on the opening end side. The contents are naturally dropped from the contents outlet of the inner bag. At that time, when the container is tilted (damping of the container), the entire inner bag tends to slide down from the end opening of the container. The force to slide down the entire inner bag is so great that it cannot be supported by the inner bag installation tool (such as the rope mentioned above) on the container (the inner bag itself has a pulling force. It will be torn by the), so a supporting device is installed at the open end of the container. Conventionally, there are various types of supporting devices of this type, such as those disclosed in Japanese Patent Laid-Open No. 50-82721, Japanese Utility Model Laid-Open No. 63-49392 or Japanese Utility Model Publication No. 2-3628. Are known.

[0004]

[Problems to be solved by the device]

 However, the conventional supporting devices of this type have the following problems due to their complicated configurations and the large number of parts. In other words, if the structure becomes complicated, the cost of the supporting device itself will increase, which will increase the transportation cost, and if the number of parts increases, assembly and disassembly and parts management will be extremely troublesome, and loading and discharging of the contents will occur. It has been pointed out that the so-called setting time other than the required time is too long.

An object of the present invention is to solve the above-mentioned conventional problems, and a supporting device for a container, which has a simple structure and is inexpensive, has a small number of parts, and can reduce the time required for setting. To provide.

[0006]

[Means for Solving the Problems]

 The present invention is a supporting device installed in the opening of a box-shaped container having one end entirely opened for entrance and exit and having longitudinally extending concave grooves formed on both side walls near the opening. And two sets of horizontal steel members mounted between at least two vertical steel members that are spaced apart from each other, and two sets of pedestals are respectively aligned with the recessed grooves on both side walls of the container. Standing upright on the surface and closely fixed to each side wall, both ends of the transverse beam are inserted into the groove through the vertical steel members of the rack, and placed on the horizontal steel members of each rack.

[0007]

[Action]

 According to the supporting device for a container of the present invention, the two pedestals are erected on the floor of the container at positions aligned with the recessed grooves on both side walls of the container, and fixed in close contact with the side walls. Then, each of the lateral beams is passed through each of the racks to enter the concave groove, and is supported on the horizontal steel material of each rack. After the contents are filled in the inner bag installed in the container and transported, and then the container is dumped for discharge, the inner bag is supported while the lateral beam of the supporting device is loaded. The stand itself, which is installed so as to project from the side wall of the container, also receives and supports both sides of the end surface of the inner bag. At that time, since both ends of the lateral beam pass through each hanging table and enter the concave groove on the side wall of the container, this does not serve as a locking part and the hanging bag is not pushed out by the inner bag, and the inner bag is moved horizontally. Firmly support with directional beams.

【Example】

 Hereinafter, a supporting device for a container according to the present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 shows a supporting device 10 for a container according to a first embodiment of the present invention installed in the container A. The container A has a box shape in which one end surface is opened to form an opening 1 and is defined by the floor surface 2, the upper wall 3, the side walls 4,5, and the end wall 6 facing the opening 1, Doors 7 for opening and closing the opening 1 are provided on both sides of the opening 1.

Such a container A is well known, and many such containers A are provided with a groove 8 extending in the longitudinal direction on both side walls 4 and 5 near the opening 1. The support device 10 of this embodiment comprises two sets of pedestals 11 and at least one lateral beam or stiffening body 12, and each pedestal 11 is aligned with the recessed grooves 8 on both side walls 4 and 5 of the container. Then, the container A is erected on the floor surface 2 of the container A and is closely fixed to the side walls 4 and 5.

That is, as shown in FIG. 2, each hanging table 11 includes two parallel vertical steel members 11a and 11b arranged at substantially the same interval as the width of the concave groove 8 of the container side walls 4 and 5. And a plurality of horizontal steel members 11c connected to the vertical steel members 11a and 11b at their ends. This horizontal steel material 11c has a function to set and support the horizontal beam 12 at a predetermined height position from the container floor surface 2 and to maintain the space between the vertical steel materials 11a and 11b of the stand itself. Even if only one directional beam 12 is provided, it is necessary to provide a plurality of directional beams 12.

As shown in FIG. 3, the two sets of the pedestals 11 which are erected on the floor surface 2 in close contact with the container side walls 4 and 5 at the position aligned with the concave groove 8 of the container side wall are provided by the projecting rod 13 as shown in FIG. It is firmly fixed. This strut bar 13 has a length longer than the interval between the vertical steel members 11a, 11a or 11b, 11b of the two sets of the facings 11 and shorter than the interval between the recessed grooves 8, 8 of the container side walls 4, 5. A threaded portion 13a is formed at both ends, and a nut 14 having a maximum outer diameter larger than the space between the vertical steel members 11a and 11b of the hanging base 11 (approximately equal to the width of the groove 8) is formed on the threaded portion 13a. Are screwed together.

When two sets of the pedestals 11 are closely attached and fixed to the inner wall of the container by using the projecting rods 13, both ends of the projecting rods 13 are vertically attached to each other as shown in FIG. It is placed horizontally between the steel materials 11a and 11b and arranged horizontally, and each nut 14 is rotated so as to move toward the end of the tension rod 13. As a result, the nuts 14 abut the vertical steel members 11a and 11b of the racks 11 so as to straddle the vertical steel members 11a and 11b, and press the racks 11 against the side walls 4 and 5 of the container A to fix them. It goes without saying that the strut bar 13 itself also has the function of the lateral beam.

Next, the operation of supporting the inner bag B in the container A by the supporting device 10 of this embodiment will be described. First, the inner bag B is installed in the container A, and then the two sets of the pedestals 11 are erected on the floor 2 at a position aligned with the concave groove 8 in the vicinity of the opening of the container 1, and then the above-mentioned strut bar 13 is attached. After mounting, each hanging stand 11 is fixed while being pressed against the side walls 4 and 5 of the container. Then, a predetermined number of lateral beams 12 are introduced at both ends thereof into the groove 8 through the vertical steel members 11a and 11b of the racks 11, respectively, and are provided at a predetermined height of the racks 11 respectively. It is supported by being placed on the horizontal steel material 11c.

When the inner bag B and the supporting device 10 are set in the container A in this manner, powder or powder is supplied from the content filling port 9 formed on the upper end surface of the inner bag B on the container opening side by the expediting means. The granular contents are filled. When the inner bag is filled with the contents, the inner bag tries to bulge toward the opening 1 side, which is not restricted by the wall surface of the container A, but the end of the inner bag is arranged at a predetermined position. The lateral beams 12 prevent the bulging.

When the container A is transported to the destination, the container A is dumped there. At that time, a discharge port is usually formed in the lower part of the end surface of the inner bag B on the container opening side. However, an inner bag having no discharge port is cut to form a discharge port when discharging. Then, the contents are discharged from this discharge port by spontaneous fall due to its own weight.

At that time, a component force corresponding to the tilting angle due to the damping of the container A in the total weight of the contents in the inner bag B is applied to the lateral beam 12 and at the same time, protrudes from the inner surfaces of the side walls 4 and 5 of the container A. The rack 11 itself installed in this state also receives both sides of the end surface of the inner bag B.

At that time, the rack 11 receives a force to be pushed out by the end surface of the inner bag B, but both ends of the lateral beam 12 pass through between the vertical steel members 11 a and 11 b of the rack 11 and the container A Since it is in the concave groove 8 of the inner bag B, it serves as a locking portion to hold the stand 11 in position, which strongly prevents the inner bag B from slipping off the container A, and the safety of the contents. In addition, it is quickly discharged.

By the way, the above-mentioned supporting device 10 supports the end portion of the inner bag B filled with the content in the opening 1 of the container A, but it is necessary to discharge the content, which is a powder or granular material, in the inner bag B. When the container A is tilted, the left and right corners of the inner bag B should be supported in a tapered shape so that the powder particles can easily concentrate on the outlet provided on the end surface of the inner bag B on the container opening side. Is preferred.

Therefore, in actual use, as shown in FIG. 4, triangular inclined plates 15 may be arranged at both left and right corners of the opening 1 of the container A. In such a case, the triangular inclined plate 15 may be a box type as shown in FIG. 5, a T type as shown in FIG. 6, or a notched single plate type as shown in FIG. If it is used and placed so as to be locked at the corner between the vertical steel material of the hanging stand 11 and the side wall surface of the container, it is possible to hold the position against the pushing force received by the inner bag B without using a special support tool. There are advantages.

Next, FIGS. 8 and 9 show a supporting device 20 for a container according to a second embodiment of the present invention. In the supporting device 20 of this embodiment, the hanging table 21 is composed of two hollow vertical steel members 21a and 21b having a rectangular cross section, which are arranged in parallel with each other with a gap substantially the same as the width of the groove 8 of the container A. Both ends of the horizontal steel material 21c are fixed by welding or the like to a predetermined position on the outer surface to form a ladder shape.

An open groove 22 extending in the longitudinal direction is formed on the side surfaces of these two vertical steel members 21 a and 21 b facing each other. A horizontal H-shaped fixing metal fitting 23 is arranged on the pedestal 21 such that its left and right end portions 23a and 23b are slidably fitted in the hollows of the vertical steel members 21a and 21b, respectively, and the vertical steel members 21a and 21b are opened. A hook 24 with a thread is inserted through a through hole and a wing nut 25 is screwed into a central connecting portion 23c that connects the left and right end portions 23a and 23b via the groove 22.

According to the supporting device 20 of this embodiment, many containers A have different positions depending on the container in the recessed grooves 8 formed in the side walls 4 and 5, as shown in FIG. The horizontal bar 8a is attached. Therefore, when the hanging base 21 is installed, the fixing member 23 is slid up and down to engage the hooked portion of the threaded hook 24 inserted through the central connecting portion 23c with the horizontal bar 8a. Then, by tightening the wing nut 25, the hanging table 21 is fixed so as to be pressed against the side walls 4 and 5 of the container A.

After that, similarly to the embodiment shown in FIG. 1, the lateral beam 12 enters both ends of the lateral beam 12 into the concave groove 8 through the vertical steel members 21 a and 21 b of the mounting table 21, and It is supported by being placed on top. According to such an embodiment, the metal fitting for fixing the mounting base 21 is provided on the mounting base 21 itself, so that the fixing metal fitting can be easily managed without being lost and the setting work can be facilitated.

FIG. 10 shows a pedestal 31 of a supporting device for a container according to a third embodiment of the present invention. The hanging base 31 is formed so that the vertical steel members 31a and 31b having the open grooves 32 similar to those of the hanging base 21 in the above-described second embodiment and having a certain thickness are made to face the open groove 32. The connecting members 35 are arranged in parallel and fixed to the outer surfaces of the upper and lower parts thereof by welding or the like for maintaining a distance and being integrated.

A large number of pin members 33 are pivotally attached to one side of one vertical steel member 31a at predetermined intervals in the height direction of the vertical steel member. When the pin member 33 is rotated around the one end pivotal portion on the side surface of the other vertical steel member 31b having substantially the same height as the pivotal attachment portion at one end of each pin member 33, the gap between the vertical steel members 31a and 31b is increased. A catch 34 is attached to receive the other end so as to be horizontal across the part.

The pin member 33 has the same function as the horizontal steel material 11c of the hanging base 11 in the first embodiment described above, and the reason why it is rotatable is as follows. For example, in the case of the supporting device 10 for a container according to the first embodiment, when the horizontal spacing of the horizontal steel members 11c supporting the horizontal beam 12 is narrow, the horizontal beam 12 is provided at a predetermined position on the mounts 11 on both sides. There is a problem that it cannot be laid over the horizontal steel material 11c.

That is, since the lateral beam 12 is longer than the length between the pedestals 11 installed on the inner surfaces of the opposite side walls 4 and 5 of the container A as described above, one end of the lateral beam 12 has a predetermined lateral width of the one pedestal 11. The horizontal beam 12 does not become horizontal even if it is inserted into the groove 8 of the container A through the space between the vertical steel materials 11a and 11b on the steel material 11c, and the upper horizontal steel material 11c on the other stand 11 interferes. Therefore, there is a case where it does not ride on the corresponding horizontal steel material 11c (at the same height position). In such a case, it is necessary to temporarily remove the upper horizontal steel material 11c of the other pedestal 11, so that this horizontal steel material is a pin member rotatably attached to the vertical steel material.

Therefore, when the transverse beam 12 is installed by using the mounting base 31 in the third embodiment, the lowermost pin member 33 is left first for at least the other mounting base 31 and All of the upper pin member 33 is removed from the receiving metal 34 to open the space between the vertical steel members 31a and 31b so that one end of the lateral beam 12 is placed on the lowermost pin member 33 of the one pedestal 31. The container A is inserted into the groove 8 and the other end is inserted into the space between the vertical steel members 31a and 31b of the other pedestal 31 which is open. Supported by. At this point, the other end of the lateral beam 12 has already entered the groove 8 of the container A.

Thereafter, when the next lateral beam 12 is installed, the pin member 33 immediately above the lowermost pin member 33 on the other rack 31 is rotated to be hooked on the receiving metal 34, and The lateral beam 12 is hung on the carriage 31 in the same manner as described above. This operation is repeated as it goes up, and a predetermined number of lateral beams 12 are installed.

As is apparent from the above, it is sufficient that there is only one hanging base that uses the horizontal steel material as such a rotatable pin member, and the other one is the first embodiment or the second embodiment. It may be a pedestal equipped with a fixed horizontal steel material as described in. Although not shown in FIG. 10, the installation of the hanging table 31 on the inner surfaces of the side walls 4 and 5 of the container A has been described in the projecting rod 13 described in the first embodiment or the second embodiment. It can be performed by a fixing means such as a fixing bracket 23, a screw hook 24, and a wing nut 25.

FIG. 11 partially shows a rack 41 of a supporting device for a container according to a fourth embodiment of the present invention, and this rack 41 is capable of rotating the rack 31 of the third embodiment. In place of the pin member 33 attached to the above, a pin member 43 that is removable by insertion is provided. That is, a through-hole is formed in each of the vertical steel members 41a and 41b at each predetermined height, and a rod-shaped pin member 43 is inserted into the through-hole to form a horizontal steel member that supports the lateral beam 12. The other points are similar to those of the rack 31 in the third embodiment.

Further, FIG. 12 shows a pedestal 51 in a supporting device for a container according to a fifth embodiment of the present invention. Like the hanging stands 31 and 41 in the third and fourth embodiments, this hanging stand 51 also has a bolt 53a and a nut 53b in place of the insertion pin member 43 of the fourth embodiment so that the horizontal steel material can be removed. It was done. According to this, since the bolt 53a acting as a horizontal steel member is fastened and fixed to the vertical steel members 51a and 51b by the nut 53b, it does not fall out, and the safe and reliable support of the lateral beam 12 is guaranteed. ..

When the bolts 53a are used as the horizontal steels in this way, the vertical steels 51a and 51b can be simply steel plates. To install such a hanging base 51 on the container side wall, a screw hook 24 similar to the fixing means of the hanging base 21 in the second embodiment is used. The wing nut 25 is screwed through the holes of the fixing plate 54 arranged on the front side of the vertical steel members 51a and 51b. The procedure for installing the pedestal 51 using the threaded hook 24 is exactly the same as in the case of the second embodiment, so its explanation is omitted. The reference numeral 55 indicates a connecting plate having exactly the same function as the connecting member 31c of the hanging base 31 in the third embodiment.
