Description

Cargo box frame and manufacturing process with excellent cohesion {CARRYING BOX FOR FREIGHT HAVING IMPROVED BINDING STRENGTH AND MANUFACTURING PROCESS THEREOF}

The present invention relates to a frame and a manufacturing process for a cargo box having excellent binding force. Specifically, the present invention relates to a frame and manufacturing process of a cargo transport box made of wood for transporting a special fluidic material, such as rubber or a bale, particularly a synthetic resin bale such as a polyethylene liner, stored in a cargo transport box.

In general, a box for packaging for cargo transport is a kind of storage mechanism that is formed to efficiently and economically store and move various kinds of cargo.

In addition, the shape of a box for packaging usually used is a method in which front and rear plates and both sides plates, which are formed having a large predetermined size, are assembled in a rectangular shape.

In particular, in the case of cargo with fluidity such as rubber, a box made of wood plywood is mostly used.

The reason is that special cargo such as rubber has high fluidity, so when iron is used, it is easily crushed by the flow force of the rubber material and the box itself weakens the binding force, making it difficult to transport. There is a problem with going out a lot.

In addition, since most of the transport boxes have a limit in recycling after being used once, most of them must be disposed of.

Accordingly, cargo transport such as rubber material, which is inexpensive and has high fluidity, uses a cargo box made of mostly wood.

The reason is that wood has strong tension, can withstand the repulsive force of fluid materials, and is inexpensive.

Currently, a number of domestic applications for shipping boxes for transporting cargo using wood have been in progress.

Most of the currently used transport boxes are installed upright in the corners of the plate frame 20 and the plate frame 20 positioned above the bottom pallet 10, basically having a predetermined width and height, as shown in FIG. 1 . The end plate 40 and the finish plate 40 are installed in the side frame 30 in which the insertion groove 31 is formed and the insertion groove 31 of the side frame 30 to shield the inside and the outside. ) in the state of being composed of the upper frame 50 installed on the upper part, the shape of the packaging box can be firmly maintained by using a separate clamp 70 .

However, in the packaging box as described above, the clamps 70 must be removed in the process of dismantling after transportation. Complaints such as consumption were caused.

Therefore, as a way to solve the above problems, domestic utility model registration No. 20-0412733 'packaging box' was developed.

The basic configuration of the packaging box is the same as that of the former, as shown in FIG. 1, but by forming the assembly means 60 at the interconnection position of the plate frame 20 and the side frame 30, as in the prior art. It is configured so that the shape of the packaging box can be firmly maintained without the clamp 70, and at the same time assembling and dismantling work can be easily performed.

That is, as shown in FIG. 2 , the assembling means 60 forms a fitting hole 61 on one side of the edge of the plate angle 20 , and a predetermined outside of the lower side of the side angle 30 . It is composed of the bent piece 62 protruding at intervals, and the finishing piece 33 is provided at the upper end of the side frame 30 having the insertion groove 31 so that the finishing piece 33 connects the finishing plate 40 to one end. By holding the, the finishing piece 40 was configured to prevent the phenomenon from being lifted upwards.

However, looking at the structure of the side frame 30, as shown in FIG. 2, a 'L'-shaped frame was fused to each other using a welding means to a "L" or "B"-shaped grid frame.

This welding method takes a lot of time to manufacture, and since a person has to hold the frame and the frame to proceed, there is a problem in that the manufacturing cost increases due to labor costs.

In addition, in order to connect the pallet 10 and the plate frame 20, the worker must use a drill to drill holes in the metal plate frame 20 and then fix them with screws, which takes a lot of work time. there was

In addition, the bent piece 62 constituting the assembly means 60 is formed in the lower part of the side frame 30. If the bent piece is made in advance in this way, it occupies a lot of space by the protruding part when loading the material, Also, due to the protruding surface, injuries were frequently caused by direct or indirect mistakes of the operator during transportation or even after assembly was completed.

At this time, in the process of assembling by inserting the closing plate 40 into the insertion groove 31 of the side frame 30 in a state where the side frame 30 is inserted into the fitting hole 61 of the plate frame 20, There was a disadvantage in that it was difficult to insert the finishing plate 40 due to the interference of the closing piece 33 bent at the upper end of the side frame 30 and thus the assembly time was prolonged.

In addition, it is the lower side frame 30 and the closing plate 40 to hold the cargo transport box, and the closing plate 40 is formed at both ends by the closing pieces 33 of the side frame 30 installed at the corners. It is pressed and fixed.

However, in order to transport products with a large flow width, such as rubber, although strong binding force is required, the binding force of the upper part is weak, and the box is often damaged during shipping by ship.

An object of the present invention is to provide a cargo box frame with excellent binding force that enables mass production of frames within a short time through only pressing and forming without using the conventional welding means for holding the box.

Another object of the present invention is to shorten the assembly time by allowing the frame completed as described above to be assembled on site in a state in which it is firmly fixed to the finishing plate.

The above and other objects of the present invention can all be achieved by the present invention described below.

However, in the present invention, the plate frame 20, the side frame 30 and the upper frame 50 made of a metal material of a long flat plate are respectively drawn into the press device and when the preset positions are stopped, a plurality of folding grooves are pressed by the press. The hole and the hole are formed in the shape of a development view, and are cut by a set length and transferred to a forming device, and each of the transferred plate frames 20, side frames 30 and upper frame 50 is formed by a forming device (not shown). ), it is a feature of the present invention that each is produced as a rectangular pipe or L-shaped frame.
It should be borne in mind that the present invention is a method of folding a developed shape using a forming machine, rather than a bonding method using a conventional welding means.

As shown in (a) of FIG. 4, the plate frame 20 has a long metal plate with a long folding groove 23 formed in the longitudinal direction by pressing (not shown), and the folding groove 23 ) as the center, a long locking hole 24 is drilled on either side, and at the same time a cut-out surface 25 is cut at an acute angle at the bottom at a predetermined distance from both ends, and a plurality of holes 26 are on the other side. It is formed at equal intervals and is bent in a "C" shape around the cut surface 25 by a forming device (not shown).
To elaborate, one side becomes the first side 21 fixed to the bottom pallet 10 by the long folding groove 23, and the other side becomes the second side 22 on which the finishing plate 40 is erected and fixed. ), and is bent into an approximately "L" when viewed from the side by a forming device, and bent into a "C" shape when viewed from a planar view.

Accordingly, as shown in FIG. 4(b), the plate frame 20 has a “c” shape when viewed from the top, and its cross section is approximately “b” when viewed from the side, and another symmetrical The plate frame 20 was manufactured and fixed to the upper part of the bottom pallet 10 with screws in an approximately "ㅁ" shape.

As shown in Fig. 5(a), the side frame 30 has first to fifth folding grooves 30a to 30e at predetermined intervals in the longitudinal direction by a press device (not shown) of one long metal plate. ) is formed, and then the cut surface 34 cut by a preset length by a cutting device (not shown), and the cut surface 34 of each surface formed by the first to fifth folding grooves 30a to 30e. A plurality of long cutouts 35 are formed in the direction, and at least two locking pieces 36 are formed by the long cutouts 35 .

The folding grooves 30a to 30e are pressed into "V"-shaped grooves of a certain depth.

At this time, the locking piece 36 is labeled with a first locking piece 36a and a second locking piece 36b for convenience.

In the state as described above, the insertion groove 31 having a “ yaw” shape is formed in a rectangular frame only by bending without the need for welding means by the forming device. For example, the first to sixth surfaces 31a to 31f are formed by the first to fifth folding grooves 30a to 30e.

For example, the first to sixth surfaces 31a to 31f are a third surface 31c, a sixth surface 31f, and a fourth surface ( 31d) and the five ash surfaces 31e are compressed and fixed in close contact.

As shown in FIG. 5(c), the insertion groove 31 for fitting the finishing plate 40 is formed in the portion fixed by compression compression as described above, and the caulking shown in FIG. 5(c) is formed. The part is formed after the end plate 40 is inserted.

The side frame 30 serves as a pillar for holding the box, and was required to have high strength to withstand the load during lamination.

Therefore, in the present invention, by bending the third surface 31c, the sixth surface 31f, the fourth surface 31d, and the ash 5 surface 31e to overlap each other, it is possible to obtain higher strength than the existing side frame.

In addition, the existing side frame is divided into two parts and fixed by spot welding, but the box often fails to function properly due to defective welding or torsion of the box.

At this time, the locking piece 36 is formed by the plurality of long cutouts 35, which is a "B" shape as shown in the enlarged view "B" of FIG. 3 when the user uses a tool such as pliers when assembling After being bent and inserted into the long locking hole 24 formed in the plate frame 20 , it was completely fixed to the plate frame 20 by a hammer or the like.

For example, as shown in (a) of FIG. 11, when the finishing plate 40 is formed to engage with each other, the first locking piece 36a constituting the locking piece 36 is the plate frame ( 20) is engaged with the long locking hole 24, and as shown in FIG. 11(b), in the case of a method in which the closing plate 40 is fitted front and rear, left and right, respectively, the second locking piece 36b It is engaged with the long locking hole 24 of the plate frame 20 .
