Description

  The present invention relates to a transport container that can store articles and can be transported by a forklift, and more particularly, to a transport container that can be stacked and stored when it is not used.

  With the establishment of a recycling system that collects and reuses waste and various resource waste, a dedicated container for transporting them is required. For this reason, various foldable types have been proposed for convenient transportation and storage after use.

  For example, in Patent Document 1, in order to obtain a transportation pallet that does not require attachment / detachment of a side panel or the like and can be easily nested, a pair of rear left and right support columns to a pair of front left and right support columns is provided. An L-shaped side panel that closes along the periphery is provided. The L-type side panel is pivotally supported by a pair of left and right rear columns so as to be able to form a folded posture overlapping the back panel. Further, a front panel is foldable at one front end of the L-shaped side panel. Thus, the front panel and the pair of left and right L-shaped side panels are folded so as to be stacked on the front side of the rear panel, thereby enabling nesting stacking.

  In Patent Document 2, in order to obtain a pallet for nesting that can be nested in a nesting manner with a detachable front panel, a bottom plate, left and right side panels, a rear panel, and a detachable front panel are provided. In the nested transport pallet, the removed front panel is detachably supported on the back surface of the rear panel.

  Further, Non-Patent Document 1 discloses a nesting rack of each company. These racks typically connect four upper and lower columns and the upper end of each column, two guide members that extend in the front-rear direction that are used as positioning members when stacked, and two rear-side columns. A connecting member for connecting the columns and a net-like or planar floor member constituting the floor surface are provided.

  A shipping container used for waste home appliances has a stacked structure such as a two-stage stack when used, and a so-called nesting stacked structure that extends from 5 to 10 stages from the viewpoint of securing storage space when not in use. Therefore, it is required that the upper and lower containers can be easily positioned in the stacking configuration, and that the load of the upper stage portion can be supported by the lower stage container. On the other hand, when nesting, the upper container can be easily accessed and can be converted into a container shape suitable for nesting, specifically, the front frame (panel) and the left and right side frames (panel) can be easily folded or Many things are required, such as being removable, being able to quickly return to its original shape for use, and reducing the risk of member loss when removing the member.

  Therefore, in the pallet for conveyance of the above-mentioned Patent Document 1, both side panels are rotatable around the back panel, and the both side panels are held on the front side of the back panel during nesting. However, in the transport pallet described in this publication, since the worker enters the load support base part on which the article is placed at the time of use, it is used when folded and used after housing waste home appliances and the like. In some cases, a damaged product may have fallen into the load support base and may hinder the work.

  In addition, storing both side panels on the front side of the rear panel increases the misalignment during nesting, reduces storage space efficiency, and increases the risk of falling. In addition, when stacking to use a transport pallet, it is described that the upper protruding member for positioning of the lower transport pallet is fitted to the groove member of the upper transport pallet. Consideration for stably holding the transport pallet is insufficient.

  Patent Document 2 describes that the rear panel is fixed and the left and right side panels are fixed, and only the front panel is detachable. In the conveying pallet described in this publication, since only the front panel is removed when nesting is performed, preparation for nesting is simplified. However, since both side panels and the back panel are fixed, in nesting, it is necessary to accurately position the upper transport pallet on the lower transport pallet and fit the upper transport panel to the lower transport pallet. There is a risk that the workability of the operation of the forklift is lowered.

  Non-Patent Document 1 discloses a nesting rack of each company. Unlike a shipping container, a nesting rack does not have a grid-like partition (panel) for preventing it from coming out on the side and back as a rule. When necessary, a grid-like partition (panel) is arranged around the rack as a separate unit, and it is a panel-integrated container with both a simple structure and easy nesting. However, no consideration is given to satisfying the specifications by changing the shape. In addition, the relatively large container that is the subject of the present invention is large enough to load several units on a truck with a loading capacity of 10 t, for example. Therefore, each side frame or fence is on the order of 20 kg in weight, and in this respect as well, the usage situation is different from the nesting rack.

  The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to allow a single worker to assemble and fold a relatively large shipping container safely and quickly, and to perform multistage nesting. It is to enable both stacking and stacking with a simple configuration. It is another object of the present invention to enable the above work without an operator entering the loading section of the shipping container.

  The present invention that achieves the above object is characterized in that a base, a back frame standing on the base, a pair of left and right side frames attached to the back frame via hinges, and standing on a front corner of the base. A transport container having a pair of left and right front struts and a plurality of stay bars with both ends locked to the pair of front struts, the fork of a forklift being formed in the base so that the fork can be inserted; An upper surface stacking rail that connects the vicinity of the left and right end portions and the upper end portions of the pair of front columns, and an end on both the left and right outer sides of the front column. A lower surface stacking rail that extends back and forth is provided, front and rear end portions of the lower surface stacking rail are closed with a flat plate, and a holding member that holds the front frame and the side frame are held by the pair of front columns. Holding means The side frame can be rotated about 270 ° around the back frame, and when stacking multiple shipping containers, the upper stacking rails are stacked on the lower stacking rail, and a plurality of shipping containers are stacked. In the case of step nesting, the left and right side frames are rotated and held on the back of the back frame.

  In this feature, the hinges are arranged at two positions apart from each other in the vertical direction, and it is desirable to arrange a stabilizer between the hinges arranged vertically, and the front frame is formed on the upper surface of the base. It is preferable to form a stay bar insertion hole into which both ends of the stay bar to be fitted, and hold the stay bar on the base during nesting.

  Also, in the above feature, the upper surface stacking rail and the lower surface stacking rail are preferably formed by arranging angle materials of the same size in a mountain shape, and the occupied area of the base is approximately 2150 mm in the lateral direction. The depth direction may be approximately 1700 mm, and the height from the floor surface to the upper surface stacking rail may be approximately 1800 mm. Furthermore, at the time of nesting, it is preferable that five transport containers are stacked and can be moved by a forklift.

  According to the present invention, since the left and right frames are attached to the back frame via the hinge portion and the left and right frames can be held on the back side of the back frame, a relatively large transport container can be safely secured by one operator. In addition to being able to be assembled and folded quickly, both multistage nesting and stacking are possible with a simple configuration. Further, the left and right frames and the front frame can be folded, restored, attached, and removed without an operator entering the loading section of the shipping container.

It is a perspective view of one Example of the shipping container which concerns on this invention. It is a figure which shows the relationship between the right side frame with which the container for transportation shown in FIG. 1 is equipped, a front support | pillar, and a back frame in detail. FIG. 2 is a partial view of the shipping container shown in FIG. 1, illustrating the stacking. It is the front view and side view which show the state which stacked the shipping container shown in FIG. 1 in two steps. It is a figure explaining the procedure at the time of nesting the container for transportation which concerns on this invention. FIG. 2 is a perspective view showing a state in which a plurality of transport containers shown in FIG. 1 are stacked. FIG. 2 is a front view and a side view of a state in which a plurality of shipping containers shown in FIG. 1 are stacked.

  The shipping container according to the present invention is often used for transporting waste such as home appliances and various resource garbage, but is not limited thereto, and any container that does not spill from the gap of the fence can be applied. However, since it is formed in the shape of a fence, the maximum loading mass is assumed to be about 1000 kg with a uniform load. In addition, the transport container has a base having the same structure as the pallet used in the forklift at the bottom, a rail-like frame on the upper surface side of the base, a rear frame, and left and right side frames on the rear frame, hinges It has a structure attached via. The front surface is sealed with a plurality of stay bars so that the same effect as that of a fence-like frame can be obtained. Furthermore, when empty, the left and right side frames are folded to the back side of the back frame to allow nesting up to 10 levels.

  Further, the shipping container according to the present invention is formed in a large size on the assumption of truck loading. Here, the large size means, for example, a shape that is difficult or cannot be supported by one person, or an outer frame portion that cannot be supported by one person. Thus, although it is a large transport container, even if the transport container is filled with a transported object, it can be stored in two stages.

  Hereinafter, an embodiment of a shipping container according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment of a shipping container 100 according to the present invention. In FIG. 1, articles (conveyed items) that are transported or stored in the transport container 100 together with the transport container 100 are not shown.

  The shipping container 100 includes a base 40 having a substantially rectangular shape, and a back frame 10 disposed on the back side of the upper surface of the base 40. A pair of left and right side frames 20 and 30 are attached to the back frame 10 via hinges 26. Two hinges 26 are provided at intervals in the vertical direction.

  The base 40 constituting the bottom portion has a floor plate 43 made of a rectangular plate and a fork guide 41. A left stack rail 42a and a right stack rail 42b extending in the front-rear direction are provided on the lower surface of the base 40 at both left and right ends. On the upper surface of the base, stay bar insertion holes 43a and 43b for holding a stay bar 51 for sealing the front surface of the transport container 100 are formed. The stay bar 51 has a conical shape with both ends bent 90 °. The bent portions of the stay bar 51 are fitted into the stay bar insertion holes 43a and 43b.

  The rear frame 10 is attached to the rear end of the base 40 and slightly inside the left and right ends, and extends to the upper right and left rear columns 16a and 16b, and the upper ends of the left and right rear columns 16a and 16b. And an upper frame 13 extending in the lateral direction to form an outer frame portion. A plurality of vertical frames 16c arranged at intervals in the vertical direction and a horizontal beam extending in the horizontal direction by connecting the vertical intermediate portions of the vertical frames 16c are attached to the outer frame portion.

  A front right column 14 and a left front column 15 extending upward are provided at the left and right ends of the front end of the base 40. On the front side of the left and right front supports 14 and 15, a plurality of stay bar receiving metal fittings 14c and 15c for fitting the bent portion of the stay bar 51 when the transport container 100 is used are provided at intervals in the vertical direction. Yes. Front corner plates 14b and 15b for closing the end portions of the left and right lower surface stacking rails 42a and 42b are attached to the lower end portions of the left and right front support columns 14 and 15 on the front side. Although not shown, the rear end portions of the left and right lower surface stacking rails 42a and 42b are also closed with corner plates.

  The upper right stacking rail 11 connects the upper part of the right front column 14 and the right end of the upper frame 13 of the rear frame 10, and the upper left column stacks the upper part of the left front column 15 and the left end of the upper frame 13 of the rear frame 10. The rails 12 are connected to each other. When two transport containers 100 are stacked, the right upper stack rail 11 of the lower transport container 100 is connected to the right lower stack rail 42a of the upper transport container 100 and the lower transport container. The upper left stacking rail 12 of 100 overlaps the left lower stacking rail 43a of the upper shipping container 100 so that the upper shipping container 100 can be stably held in the lower shipping container 100. Become.

  Next, the left and right side frames 20, 30 that are one of the features of the present invention will be described with reference to FIG. In the following description, only the right side frame 20 is taken up, but the left side frame 30 has the same configuration, and thus the description thereof is omitted. 2 (a) is a front view of the right side frame 20, FIG. 2 (b) is a front view of the upper stopper portion 23 constituting a part of the right side frame 20, and FIG. 2 (c) is a right side view. FIG. 2D is a perspective view of a part of the right front column 14 taken out. FIG. 2D is a cross-sectional view of the hinge 26 that rotatably attaches the frame 20 to the right rear column 16a.

  The right side frame 20 is formed in a D shape by an outer peripheral frame 21 formed by bending a single round pipe and an outer peripheral frame 22 that connects both ends of the outer peripheral frame 21. Both ends of a plurality of vertical frames 29 extending in the vertical direction and spaced apart in the front-rear direction (left-right direction in FIG. 2A) are attached to the outer peripheral frame 21. Further, a horizontal rail 25 extending in the horizontal direction is arranged so as to connect the intermediate portions of the vertical frames 29. An upper stopper portion 23 and a lower stopper portion 24 are respectively formed at the upper corner portion and the lower corner portion on the front side of the right side frame 20. An outer peripheral frame 29a extending in the vertical direction is arranged so as to connect the upper and lower stopper portions 23, 24.

  The upper stopper portion 23 and the lower stopper portion 24 have substantially the same configuration, except that the stopper mounting frame 23a that partitions the stopper portions 23 and 24 is formed symmetrically. As shown in FIG. 2B, there is a stopper mounting plate 23b formed of a long flat plate between a vertically extending portion of the stopper mounting frame 23a bent in an L shape and an outer peripheral frame 22 extending vertically. Connected horizontally.

  Cylindrical stopper support pipes 23c and 23d are attached to the front side end of the stopper mounting plate 23b and the middle part in the front-rear direction (the middle part in the left-right direction in FIG. 2B). Between the two stopper support pipes 23c and 23d and on the lower end side of the stopper attachment plate 23b, a stopper removal prevention plate 23e bent in an arc shape is attached. A stopper handle 23g is provided at a right angle to the stopper 23f at an axially intermediate portion of the stopper 23f formed of a round bar extending in the lateral direction.

  On the other hand, in the vicinity of the position corresponding to the stopper 14f on the back side of the right front column 14 facing the stopper 23f, a stopper insertion plate 14e having a long long hole formed in the vertical direction is attached. The long hole of the stopper insertion plate 14e is used as a stopper insertion hole 14f.

  When the right side frame 20 is held on the right front column 14 using the stopper portion 23 configured in this way, the portion behind the stopper handle 23g of the stopper 23f is first held in the stopper support pipe 23d. Then, the stopper handle 23g is positioned downward and held behind the stopper removal prevention plate 23e (the right side in FIG. 2B).

  Next, the right side frame 20 is positioned at a position facing the right front column 14, and after the stopper handle 23g is rotated upward, it is positioned forward beyond the stopper removal prevention plate 23e. The front portion of the stopper 23f is inserted into the stopper support pipe 23c, and the tip of the stopper 23f is inserted into the stopper insertion hole 14f of the stopper insertion plate 14e attached to the right front column 14, and the stopper 23f is inserted into the right front column 14. Engage. Thereafter, in order to prevent unintentional removal of the stopper 23f, the stopper handle 23g is rotated, and the stopper handle 23g is held in the gap between the front end of the stopper removal prevention plate and the rear end of the stopper support pipe 23c. Thereby, the right side frame 20 is securely held by the right front column 14.

  To remove the stopper 23f, the reverse procedure is followed. At this time, when the right side frame 20 is released from the right front column 14, the stopper handle 23g is positioned in a gap formed between the stopper removal prevention plate 23e and the rear stopper support pipe 23d. In this case, the front end of the stopper 23g is located inside the right side surface frame 20 rather than the outer peripheral frame 22, so that the risk of damage to the stopper 23g is significantly reduced.

  As described above, the right side frame 20 is attached to the right back column 16a via the hinge 26. Details of the hinge 26 will be described with reference to FIG. Note that the two hinges 26 arranged at an interval in the vertical direction have the same structure.

  The outer peripheral frame 21 constituting the right side frame 20 has a cylindrical shape so that the frictional resistance is reduced when the right side frame 20 is rotated. For the same reason, the right back column 16a also has a cylindrical shape. Here, the diameter of the outer peripheral frame 21 is smaller than the diameter of the right back column 16a.

  The outer peripheral frame 21 and the right back support column 16a are arranged with a space therebetween. The outer peripheral portion of the outer peripheral frame 21 is covered with a thin plate-like hinge plate 26a, and the outer peripheral portion of the right rear support column 16a is covered with a thin plate-like hinge plate 26b. Both end portions of each hinge plate 26a, 26b overlap each other.

  A stabilizer 28 extending vertically is disposed between the two hinges 26 disposed vertically, and in the gap between the outer peripheral frame 21 and the right back column 16a. The overlap portions of the stabilizer 28 and the hinge plates 26a and 26b are fastened by bolts 26c and nuts 26d. The stabilizer 28 prevents the right side frame 20 from being distorted and rotated by the rotation angle of the hinge 26 arranged at the upper portion being different from that of the hinge 26 arranged at the lower portion, and synchronizing the rotation angles of the upper and lower hinges 26. Let With such a configuration of the hinge 26, the right side frame 20 can freely rotate around the right back column 16a.

  FIG. 2 (d) shows details of the stay bar brackets 14c and 15c provided on the front surfaces of the front columns 14 and 15. FIG. The stay bar receiving brackets 14c and 15c have a shape in which a flat plate is bent in a C shape, and a bent end portion of the stay bar 51 is inserted into the stay bar receiving brackets 14c and 15c. The stay bar brackets 14c and 15c are attached at about five places with a space in the vertical direction. In addition, the front support | pillars 14 and 15 are the product made from a square-shaped steel pipe, and the base part close | similar to the base 40 hold | maintains the support rods 14d and 15d inside for reinforcement.

  Next, the stacking and nesting of the shipping container 100 configured as described above will be described. First, the case where the shipping containers 100 are stacked in two stages will be described with reference to FIGS. FIG. 3 is a front view showing how the shipping containers 100 are stacked, with only the upper left end of the lower shipping container 100 and the lower left end 100 of the upper shipping container taken out (FIG. 3). It is (a)) and a side view (FIG.3 (b)). In the stacking operation of the container 100 for transportation, the left and right are stacked at the same time. Further, the stacking of the shipping containers 100 is performed using a forklift in a state where articles are filled in the shipping container 100. In consideration of safety, the stacking is limited to two stages, but theoretically, three or more stages can be stacked.

  Adjacent to the lower end of the left front column 15 of the upper transport container 100, a left lower surface stacking rail 42b is disposed. The left lower surface stacking rail 42b is arranged in a shape that is turned upside down with the corners of the equilateral angle irons facing upward, and a recess is formed on the lower surface side. On the other hand, the upper end portion of the lower left front column 15b is covered with an upper surface plate 15a bent in a C shape, and the left lower surface stacked rail 42b is disposed in the vicinity of the inner end portion in the left-right direction of the upper surface plate 15a. The left upper stacking rail 12 having the same size as the above is disposed with its corners facing upward. A reinforcing plate 12a is fixed to the upper surface plate 15a at the front-rear direction end of the left upper surface stacked rail 12 in order to prevent deformation of the left upper surface stacked rail.

  When stacking the transport containers 100, the upper transport container 100 is pulled down so that the concave portions of the lower stack rail 42 b overlap the corners of the upper stack rail 12. At that time, since the front and rear end portions of the lower stack rail 42b of the upper transport container 100 are closed by the front corner plate 15b, the difference in the front and rear direction between the upper stack rail 12 and the lower stack rail 42b is within a predetermined range. Can fit inside. Thereby, the collapse of the load after stacking can be prevented. Further, by marking the front side of the front corner plate 15b with the triangular shape of the cross section of the lower surface stacking rail 42b (see FIG. 4), the lower surface stacking rail 42b and the upper surface stacking rail 12 by the forklift operator. Alignment work with can be speeded up.

  FIG. 4 is a front view (FIG. 4 (a)) and a side view (FIG. 4 (b)) showing a state where shipping containers are stacked in two stages. The upper shipping container 100 (C) and the lower shipping container 100 (D) are stacked using the marks 14 e and 15 e displayed on the front corner plates 14 b and 15 b. The height H of the entire shipping container when stacked in two stages is about 4000 mm, the width W is about 2280 mm, and the depth L is about 2150 mm.

  Next, an example of nesting of the shipping container 100 will be described with reference to FIGS. FIG. 5 is a diagram for explaining the nesting procedure, and is a top view of the shipping container 100. First, the stay bar 51 forming the front frame is removed from the left and right front columns 14 and 15, and the end portions thereof are inserted and held in the stay bar insertion holes 43 a and 43 b formed in the base 40. This state is shown in FIG.

  Next, the upper and lower stopper portions 23 and 24 (see FIG. 2A) formed on the left and right side frames 20 and 30 are removed, and the left and right side frames 20 and 30 are connected to the back posts 16a and 16b using the hinges 26. Is rotated outwards around (Fig. 5 (b)). Then, it is rotated by approximately 270 ° and folded to the back side of the back frame 10 in the order of the right side frame 20 and the left side frame 30. When the folding is completed, the back frame 10, the right side frame 20, and the left side frame 30 are fastened and held together with a rubber string or the like (not shown). This state is shown in FIG. When the left and right side frames 20 and 30 have been folded, the fork of the forklift is inserted into the fork guide 41 formed in the base portion, and the transport container 100 is moved.

  FIG. 5 (d) shows a state before nesting two shipping containers 100 (A) and 100 (B), and FIG. 5 (f) shows a state after nesting. The upper shipping container 100 (B) is stacked on the upper side of the lower shipping container 100 (B) so as to be inserted from the front side. The two shipping containers 100 (A) and 100 (B) are stacked while changing the position in the front-rear direction by the thickness of the left and right side frames 20 and 30 folded on the back of the back frame 10.

  A nesting storage container 200 after nesting a plurality of shipping containers 100 is shown in FIGS. 6 is a perspective view showing a state in which five shipping containers 100 are nested, and FIG. 7 is a front view and a side view showing a state in which ten shipping containers 100 are nested (FIG. 7 (a)). FIG. 7B). As described above, the position of the transport container 100 moves each time the number of steps is overlapped by the folding amount of the left and right side frames 20 and 30 in the front-rear direction. Further, when the number of steps is increased, the height is increased by approximately the thickness of 40 parts of the base in the vertical direction. The length in the left-right direction does not change. Therefore, even in the case where ten layers are stacked, the width direction length W is about 2280 mm, the height is about 3600 mm, and the depth direction length L1 is about 2760 mm. Therefore, a large number of shipping containers 100 can be stored in a small space by nesting.

  In the above embodiment, the right side frame is folded to the back side of the back frame, and then the left side frame is folded, but the order of folding may be either. Further, the shape of the stopper portion for locking the left and right side frames to the front column is not limited to the above embodiment, and may be fixed with a chain or the like. However, what was described in the said Example from the point of prevention of loss of components etc. is preferable. Furthermore, it is economical and easy to process each part constituting the left and right side frames and the back frame when a circular tube is processed.

  According to the above-described embodiment, since the steel plate (angle material or equilateral mountain steel) is used for the stacking rail, and standard products such as circular pipes are used for the left and right side frames and the back frame front frame, the transportation container is economical. Can be configured. Moreover, since the stopper portion and the hinge portion have a simple configuration, the left and right side frames can be reliably held on the front column or rotated around the back column even after many years of use.

  In addition, according to the above embodiment, the upper surface of the base is covered with a steel plate, and the back frame and the left and right side frames are formed in a lattice shape, so that small parts can be dropped or protrude from the shipping container. Can be prevented. Furthermore, it is possible to insert the fork of the forklift from the four sides of the base, and the transportation work by the forklift becomes efficient.
