Description

  The present invention relates to a foldable box pallet used when an article is conveyed using a forklift.

  Of the box pallets used for transporting goods (for example, plastic waste) using a forklift, the box pallet used for transshipment of goods using a rotating forklift whose fork rotates 360 degrees left or right is rotating. Since rotation that reverses the top and bottom is applied by a forklift, conventionally, the side wall is fixed (so-called side wall fixing type). A large number of such box pallets are necessary for the handling company, and the storage method is usually a stacking method. However, this side wall fixed box pallet has a limit on the height (number of tiers) that can be stacked for safety reasons, etc., and when not using the pallet, it must be stored with a vast storage space. There was a problem that it had to be.

  Therefore, as a technique that can solve such a problem, a foldable box pallet 1 as shown in FIG. 8 has been proposed (see, for example, Patent Document 1).

  The box pallet 1 is provided with guide frames 5 for fixing the pillars 4 at the four corners of the pallet floor having the fork insertion port 3. The pair of first side walls 2 a located at the front and rear of the box pallet 1 are inserted into the insertion holes 5 b provided in the guide frame 5 by inserting the insertion shaft rod 6 provided at the lower part of the side wall 2 a. The guide frame 5 is connected to the insertion hole 5b so that it can be tilted up and down. The pair of left and right second side walls 2b of the pallet 1 are fixed to and integrated with the two support columns 4 at both front and rear ends. The support column 4 has a folding height of the guide frame 5 and the first side wall 2a. The hinge 7 provided at a higher position is connected to the floor of the pallet 1 (that is, on the folded first side wall 2a) so that it can be tilted up and down.

When such a box pallet 1 is used, when the pallet 1 is not used, the side walls 2a and 2b can be folded and stacked in a compact manner, so that the number of steps can be increased at the same height compared to the side wall fixed box pallet. The pallets can be stacked, and the storage location problem as described above can be solved.
Japanese Patent Laid-Open No. 2005-200029

  However, in the above-described foldable box pallet 1, when the pallet 1 is folded, the first side wall 2 a positioned on the opposite side is overlapped and folded toward the floor so that one of the first side walls 2 a is folded. After folding, the operator turns around to fold the other first side wall 2a, and then folds one second side wall 2b toward the floor board, and then turns further to turn to the other second side wall. All the side walls 2a and 2b constituting the four surfaces of the box pallet 1 have to be laid down sequentially toward the floor board so as to fold 2b. Thus, in this conventional folding type box pallet 1, the folding work of the side walls 2a and 2b is very complicated. Therefore, when folding the box pallet 1 by a single work, a large amount of work is required. There was a problem that it would take a lot of effort.

  Therefore, the main problem of the present invention is that the pallet can be easily folded and assembled by one person, and does not take up space for storage, and is a folding type suitable for transshipment or dumping of articles using a rotating forklift. Is to provide a box pallet.

It is characterized by being provided at a higher position.

  The invention described in claims 5 and 6 has the same effect as the box pallet 10 described in claims 2 and 3.

  According to the present invention, the folding and assembling of the pallet can be performed safely and easily by one person, and the folding box is suitable for transshipment or dumping of articles using a rotary forklift without taking up space for storage. Pallet can be provided.

  Hereinafter, the present invention will be described in detail according to illustrated embodiments. FIG. 1 is a perspective view showing a box pallet 10 having a lid 10b according to an embodiment of the present invention. FIG. 2 is a front view of the box 10b with the lid 10b removed. The box pallet 10 stores articles. In general, it is composed of a substrate 12, a pair of side plates 14, 16, a front plate 18 and a rear plate 20.

  The substrate 12 serves as a base of the box pallet 10, and has a vertical cross section made of a metal material such as iron or stainless steel and has a substantially L-shaped (for example, an angle material), and a floor plate receiving frame 22 that is framed in a rectangular shape in plan view. And a floor plate 24 mounted on the floor plate receiving frame 22 and made of a lightweight plate material such as plastic corrugated cardboard.

  On the lower surfaces of the four corners of the floor plate receiving frame 22 constituting the substrate 12, a pedestal 26 having a substantially L-shaped horizontal section made of a metal material such as iron or stainless steel is integrated by a joining method such as welding or bolting. Furthermore, a frame-like lower deck plate 28 made of a metal material such as iron or stainless steel and connecting adjacent leg columns 26 is joined to the lower portion of the leg column 26 by welding or screwing. Are attached in one piece. Further, in the central portion of the space surrounded by the floor plate receiving frame 22, the pillars 26, and the lower deck plate 28, the lower piece of the floor plate receiving frame 22 and the lower deck plate 28 are made of a metal material such as iron or stainless steel. The intermediate pedestal 30 connecting the two is integrally attached by a joining method such as welding. A space surrounded by the floor plate receiving frame 22, the pedestal column 26, the lower deck plate 28, and the intermediate pedestal column 30 is an insertion portion S into which the fork P of the forklift is inserted. Although not shown in the drawing, a reinforcing frame that supports the floor plate 24 is attached to the lower portion of the floor plate receiving frame 22.

  Further, at the center of the surface of the intermediate pedestal 30 attached to the front side and the rear side of the substrate 12, there is a downward hook F1 on which a rubber rope 66 of the lid 10b described later is hooked when the box pallet 10 is folded. It is attached.

  The four corners of the floor plate receiving frame 22 constituting the substrate 12 are made of a metal material such as iron or stainless steel, and are connected to the side plate support pieces 32a facing the side surfaces of the side plates 14 and 16, and the side plate support pieces 32a. The L-shaped short column 32 having a substantially L-shaped horizontal section and having a surface abutting piece 32b that abuts against the surface of the side plates 14 and 16 protrudes toward the upper surface side of the substrate 12 and is joined by welding or the like. Are attached in one piece. Of course, you may attach both 32a and 32b separately.

  The L-shaped short pillar 32 is a member for guiding or regulating the movement of the side plates 14 and 16 in the first and second embodiments described in claims 2 and 3, and as shown in FIG. 3, the side plate support piece 32a. Is provided with a notch 34a extending obliquely upward from the vicinity of the base where the surface abutting piece 32b is continuously provided and extending upward from its tip and then horizontally cut out and opened at the outer edge of the piece. Yes. This notch 34a is supported by the inclined portion 34S and the upwardly extending portion 34u by sealing the opening provided in the outer edge portion of the notch 34a after the support shaft 42 of the side plates 14 and 16 described later is attached. The shaft 42 serves as a guide hole 34 that is movably engaged. Here, the lower end portion of the inclined portion 34S of the guide hole 34 is in the vicinity of the side plate abutting piece 32b. When the support shaft 42 is located at this position, the side plates 14 and 16 are erected in contact with the side plate abutting piece 32b. Therefore, it is referred to as “side plate standing position T”. When the support shaft 42 is positioned in the upwardly extending portion, the lower end portions of the folded side plates 14 and 16 include the lower end portions of the front and rear divided pieces 18a to 20b, and the side plate contact pieces 32b and the substrate. 12 is located sufficiently away from the top surface of the plate 12 and can be smoothly rotated and fallen without any catch. This position is referred to as a “side plate fallen position O”.

  As shown in FIGS. 2A to 2C, in the guide hole 34, the height H of the front and rear plates 18, 20 and the side plates 14, 16 is smaller than half of the length between the side portions of the substrate 12. It is divided into the case where it is set (first embodiment) and the case where it is set large (second embodiment). In the former case, the tips of the side plates 14 and 16 do not interfere with each other when folded, so the same symmetric shape However, in the latter case, since the interference occurs, the dimensions (height dimension h3) are different, and there are a long one (indicated by h2) and a short one (indicated by h1) to avoid interference. In this case, the shorter dimension is defined as “side plate collapse position O ′”. Note that the different dimensions are such that the side plate collapse position O ′ of one side plate 14 or 16 is at least higher than the front and rear divided pieces folded at least than the other side plate collapse position O “thickness W = h3 or thickness W. <H3 ”. In this case, the sum of the widths of the front and rear divided pieces 18a and 20b folded on the same side plate 14 and the front and rear divided pieces 18b and 20a folded on the same side plate 16 is smaller than the width of the side plates 14 and 16. The front / rear surface split pieces 18a, 20b and the front / rear surface split pieces 18b, 20a do not overlap each other as in the case of the above, so the “thickness W” when folded is equal to one, but as in the case of “large” When it overlaps, it becomes two sheets. Therefore, the “thickness W” varies depending on the state of the height H.

  The length of the portion 34u extending above all the guide holes 34 (this portion becomes the side plate collapse position O or O ′) is 2 or 3 times the thickness W of the side plate 14 (16) when folded. It can also be set to the above size. In such a case, since the support shaft 42 stops at the appropriate position of the portion 34u extending above the guide hole 34 and turns down, either of the side plates 14 and 16 is put down on the substrate 12 first. However, the side plates 14 and 16 can always be laid down in a state of being substantially parallel to the substrate 12. That is, it is not necessary to consider the order in which the side plates 14 and 16 fall down. Moreover, since the same thing can be used as the L-shaped short pillar 32 attached on the diagonal of the board | substrate 12, a number of parts can also be reduced.

  Further, as a method of sealing the opening of the guide hole 34, as shown in FIG. 3, a metal plate 34b is disposed in the opening, and the metal plate 34b is fixed to the L-shaped short column 32 with a bolt 34c. Is mentioned.

  The side plates 14 and 16 are plate-like members constituting the side surface of the box-like box pallet 10, and protect the outer edge of the plate material 40 made of a plate material 40 made of plastic cardboard or the like and a metal material such as stainless steel or aluminum. The frame 36 and a fixing means such as a rivet 38 that fixes the frame 36 to the outer edge of the plate member 40 are configured.

  In the case of the present embodiment (FIG. 4), since the front and rear divided pieces 18a to 20b hinged to the same side plates 14 and 16 overlap each other, the side plates 14 and 16 have a substantially L-shaped horizontal section when standing. The length y of the short side portions 142 and 162 is formed to be substantially equal to the thickness of the front divided piece 18a or the rear divided piece 20a that is folded inside. If they do not overlap, the short side portions 142 and 162 are unnecessary, and only the side plate main bodies 141 and 161 are sufficient.

  Support shafts 42 project from the lower portions of the front and rear side surfaces of the side plates 14 and 16, and the side plates 14 and 16 center on the support shaft 42 engaged with the guide hole 34 as described above. They are going to fall or stand up.

  Further, a locking member 44 for locking a catch clip C of the lid 10b described later is attached to the upper center of the outer surface of the side plates 14 and 16.

The front plate 18 is a plate-like member that constitutes the front surface of the box-shaped box pallet 10, and has a wide front divided piece 18 a and a narrow front divided piece formed at substantially the same height as the side plates 14 and 16. 18b is configured to be able to engage and disengage the opposite side portions .

  The front split pieces 18a and 18b are made of a plate material 50 made of plastic cardboard, a frame 46 made of a metal material such as stainless steel or aluminum, and a rivet for fixing the frame 46 to the outer edge of the plate material 50. 48 and other fixing means.

  The front divided pieces 18a and 18b are hinged to the front side portions of the side plates 14 and 16 via hinges 52 and 54, respectively, so that they can be folded toward the lying side surfaces of the adjacent side plates 14 and 16. (See FIGS. 3 and 4). In addition, a latch lock such as a round drop 56 is attached to the adjacent side portion between the front divided pieces 18a and 18b and the proximity portion between the lower end portion of the front divided piece 18a and the front side portion of the substrate 12, and a box lock is attached. When the pallet 10 is assembled and used, the front split pieces 18 a and 18 b are integrated to function as the front plate 18.

  A downward hook F2 to which a rubber rope 66 of the lid 10b described later is hooked when the box pallet 10 is assembled and used is attached to the upper center of the surface of the front plate 18.

The rear plate 20 is a plate-like member that constitutes the rear surface of the box-shaped box pallet 10, and has a wide rear divided piece 20 a and a narrow rear divided piece formed at substantially the same height as the side plates 14 and 16. 20b is configured to be able to engage and disengage the opposite side portions (see FIGS. 1 and 4) .

  As described above, the sum of the widths of the front and rear divided pieces 18a, 18b, 20a, 20b in the engaged state may be equal to the width of the side plates 14, 16, or may be larger or smaller. Is different.

  The rear split pieces 20a and 20b are not shown in the drawing, but, similar to the front split pieces 18a and 18b described above, the plate member 50 made of plastic cardboard or the like and the plate member 50 made of a metal material such as stainless steel or aluminum. The frame 46 is configured to protect the outer edge, and fixing means such as a rivet 48 that fixes the frame 46 to the outer edge of the plate member 50.

  The rear divided pieces 20a and 20b are also hinged to the rear side portions of the side plates 16 and 14 via hinges 52 and 54, respectively, so that they can be folded toward the lying side surfaces of the adjacent side plates 16 and 14. (See FIG. 4). In addition, a latch lock such as a round drop 56 is attached to the abutting side portion between the rear surface divided pieces 20a and 20b and the lower edge portion of the rear surface divided piece 20a and the rear side portion of the substrate 12, and a box lock is attached. When the pallet 10 is assembled and used, the rear surface split pieces 20 a and 20 b are integrated to function as the rear plate 20.

  A hook F <b> 2 is attached to the upper center of the surface of the rear plate 20 so that a rubber rope 66 of the lid 10 b described later is hooked when the box pallet 10 is assembled and used.

  The lid 10b is for closing an opening provided on the upper surface of the box pallet 10, and the box 10b is detachably fitted to the upper part of the box pallet 10 with a metal material such as stainless steel or aluminum. The frame 58 is formed in an inner peripheral shape slightly larger than the outer peripheral shape of the pallet 10 and a plate member 62 made of plastic cardboard or the like and fixed to the upper surface of the frame 58 by a fixing means such as a rivet 60. .

  Here, when the other box pallet 10 is placed on the lid body 10b on the upper surface of the corner portion of the frame body 58 constituting the lid body 10b, the leg pillars 26 of the other box pallet 10 are guided. A stacking guide 64 is provided to store the lid, and the lid 10b attached to the box pallet 10 is detached in cooperation with the locking member 44 at the center of the side of the frame 58 that contacts the side plates 14 and 16. A catch clip C is fixed so as to prevent it. In addition, a pair of hooks F3 is attached to the side of the frame body 58 that contacts the front plate 18 and the rear plate 20, and a rubber rope 66 is installed on the hooks F3.

  Next, the operation of the box pallet 10 of the present embodiment configured as described above will be described. When using the box pallet 10 of the present embodiment, as shown in FIG. 1, the side plates 14 and 16 are erected and the box pallet 10 is assembled.

  On the other hand, when the box pallet 10 is not used, the box pallet 10 is folded by the procedure shown in FIG. 4 in order to effectively use the space at the work site. That is, first of all, the front drop pieces 56a and 18b constituting the front plate 18 and the rear face division pieces 20a and 20b constituting the rear plate 20 are released by releasing the round drop 56 attached to the front plate 18 and the rear plate 20. In a movable state (see FIG. 4A).

  Subsequently, the narrow front divided piece 18b and the wide rear divided piece 20a are folded toward the side plate 16 (see FIG. 4B), and the wide front divided piece 18a and the narrow rear divided piece 20b are joined. After folding toward the side plate 14, the side plates 14 and 16 are pushed down in the order of the side plate 14 and then the side plate 16 (toward the side plates 14 and 16 facing each other).

  Specifically, while the side plates 14 and 16 are lifted upward so that the support shafts 42 of the side plates 14 and 16 are positioned at the “side plate collapse position O or O ′” at the upper end of the guide hole 34, The side plates 14 and 16 are rotated around the center 42 and fall down toward the substrate 12 (see FIG. 4C). Thereby, folding of the box pallet 10 is completed.

  Then, the lid body 10b is attached to the upper part of the folded box pallet 10, and the rubber rope 66 of the lid body 10b is hooked on the hook F1, so that all the folding operations of the box pallet 10 of this embodiment are completed.

  The box pallet 10 folded in the above procedure is stacked and stored in multiple stages (two stages in the case of this drawing) as shown in FIG.

  When assembling the box pallet 10, the procedure may be performed in the reverse order of the folding procedure.

  Further, in the above-described embodiment, when the L-shaped short column 32 in which the side plate support piece 32a and the surface contact piece 32b are integrally formed is attached to the four corners of the floor plate receiving frame 22 constituting the substrate 12. However, the side plate support piece 32a and the surface contact piece 32b may be attached separately.

  Next, a box pallet 10 of another embodiment shown in FIGS. 6 and 7 will be described. In this case as well, the height H of the side plates 14 and 16 is taken into consideration as described above. In this case, the difference from the first embodiment is that the guide hole 34 is not provided in the L-shaped short column 32, and instead, the side plate support piece 70 and the support shaft 22a are used for connecting the substrate 12 and the side plates 14 and 16. It is a point using. Since the other parts are the same as those of the second and third embodiments, the description of the embodiment is used to replace the description of the present embodiment.

  The side plate support piece 70 corresponds to the side plate support piece 32a of claims 2 and 3, and the front and rear plates 18 and 20 and the side plates 14 and 16 are not more than ½ of the width between the side edges of the substrate 12. In the case where they do not overlap at the center of the substrate 12, the side plate support pieces 70 are symmetrical (third embodiment), but the width is ½ or more, and the side plate support pieces 70 are at the center of the substrate 12. In the case of overlapping, those having different dimensions are used as will be described later (fourth embodiment). Hereinafter, the case where the former does not overlap at the center of the substrate 12 will be described.

  The side plate support piece 70 is a substantially L-shaped metal plate material that connects the substrate 12 and the side plates 14 and 16, and includes a side plate contact piece 70 a that is attached to the side edges of the side plates 14 and 16, and the side plate contact piece 70 a A substrate contact piece 70b extending from below the lower edge of the end of the side plate contact piece 70a so as to be orthogonal to each other. Among these, a guide hole 70c into which a support shaft 22a protruding in a horizontal direction from the floor plate receiving frame 22 of the substrate 12 is fitted and inserted into the tip end portion of the substrate contact piece 70b (in the guide holes 34 of claims 2 and 3). Equivalent) is drilled. Since the support shaft 22a is below the lower edge of the side plates 14 and 16, the guide hole 70c may be a simple round hole. However, in order to facilitate the fall of the side plates 14 and 16, as shown in the figure, the substrate contact piece 70b It is good also as a long hole along.

  When connecting the substrate 12 and the side plate 14 via the side plate support piece 70, as shown in FIG. 7, the side plate contact piece 70a is placed on the frame 36 at the side end (lower end) of the side plate 14. The support shaft 22a protruding from the floor plate receiving frame 22 of the substrate 12 is inserted into the guide hole 70c of the substrate contact piece 70b. The side plate support pieces 70 are attached to both the front and rear sides of the base material 12 and the side plate 14. By connecting the substrate 12 and the side plate 14 via the side plate support piece 70 in this way, the side plate 14 can be tilted toward the substrate 12 with the support shaft 22a as the center of rotation.

  On the other hand, in the latter case where the side plates 14 and 16 overlap each other in the center of the substrate 12, the length L1 of the substrate contact piece 70b of one side plate support piece 70 is the other side plate as shown in FIG. It is longer than the length L2 of the substrate contact piece 72b of the support piece 70 by the thickness W when the front divided piece 18a (18b) and the rear divided piece 20b (20a) are folded on the side plate 14 (16). It is configured. By doing so, even when the pair of side plates 14 and 16 facing each other overlap each other when lying down, the side plates 14 and 16 are prevented from interfering with each other, and the side plates 14 and 16 are substantially separated from the substrate 12. You can lie down in parallel.

  Thus, similarly to the second and third aspects, in the two embodiments of the fifth and sixth aspects, the folded side plates 14 and 16 can be horizontally superimposed on the substrate 12. Then, the lid 10b is crowned on the folded box pallet 10, fixed with the rubber rope 66, and stacked, which is the same as the invention described in claims 1 and 2.

  According to the box pallet 10 of the present embodiment, the front plate 18 constituting the front surface of the box pallet 10 is composed of the front divided pieces 18a and 18b, as in the first embodiment described above. The rear plate 20 constituting the rear surface is constituted by rear divided pieces 20a and 20b, and the divided pieces 18a, 18b, 20a, 20b can be folded toward the lying side surfaces of the side plates 14, 16, respectively. Since it is hinged to the adjacent side plates 14 and 16, when the box pallet 10 is folded, as described above, the pair of side plates 14 in which the front divided pieces 18a and 18b and the rear divided pieces 20a and 20b are overlapped. , 16 lie down toward the substrate 12 to complete the folding of the box pallet 10. For this reason, the folding operation of the box pallet 10 can be performed very easily compared to the case where all four side surfaces are laid down toward the substrate.
