Japanese Patent Laid-Open No. 5-16940 JP 2002-68186 A

  According to the transported material transport pallet described in each of the above Patent Documents 1 and 2, it can be transported in a well-protected state without damaging the middle- or large-sized electronic device.

  On the other hand, when recovering the pallet after transport, in the transported material transport pallet of Patent Document 1 above, the body is removed from the pallet and folded flat, and then the folded body is placed on the pallet, and the lid is placed on the pallet. It will be covered and collected. In other words, since the collection work is performed with the pallet and the body separated, depending on the state of the collection work, a situation may occur in which the pallet is covered with the lid without forgetting to place the body on the pallet. there is a possibility. For example, when collecting a large number of transported pallets that have been transported, work to separate the pallet, fuselage, and lid, work to fold the fuselage, work to place the folded fuselage on the pallet, and cover from there In the case where work that covers the body is performed by division of labor, there is a high possibility that the above situation will occur.

  In addition, the transported material transport pallet described in Patent Document 2 has a structure in which the support is removed and stored in the pallet main body during collection. That is, since the collection work is performed in a state where the pallet main body and the support are separated, there is a problem that the possibility of forgetting the recovery of the support is particularly high. Furthermore, in the transported material transport pallet of Patent Document 2, when reassembling after collection, each support column must be erected on the pallet main body one by one, and there is a problem that the assembling work takes time.

  The present invention has been devised to solve such problems. The purpose of the present invention is to integrate the members constituting the transported material transport pallet as much as possible, thereby assembling work for transporting the transported material and after transporting. It is an object of the present invention to provide a transported material pallet that can easily perform a folding operation at the time of collection and can surely prevent the occurrence of problems such as forgetting to collect a member at the time of the folding operation.

  The transported material transport pallet of the present invention includes a transport base, a support that is provided on the transport base and is tiltable on the transport base, and a cover member that is provided between the adjacent supports. In the transported material transport pallet, the cover member is stored in a state of being folded in a space between adjacent struts tilted on the transport base. is there.

  According to the present invention, since the transport base, the support column, and the cover member, which are constituent members of the transported material transport pallet, have an integral structure, the folding operation at the time of collection can be performed smoothly.

  In this case, the support column is provided so as to be tiltable toward the central portion of the transport base with the corners of the transport base as pivot points. Thereby, a support | pillar does not protrude from a conveyance base, but a support | pillar can be folded compactly.

  The cover member is formed with a fold line so as to be folded in accordance with the tilting operation of the support column. Thereby, a cover member can also be easily folded according to tilting operation of a support | pillar. Further, the folded cover member can be easily unfolded in accordance with the upright operation of the column.

  As for the tilting structure of the column, a tilting mechanism unit that tiltably supports the lower end of the column is provided at each corner of the transport base, and the tilting mechanism unit includes the column. It has a structure provided with a sliding mechanism that can slide up and down in an upright state. On the other hand, an insertion groove portion that supports the support column is formed at each corner of the transport base by inserting the lower end of the upright support column.

  With such a structure, when the transported article is stored, the support column can be firmly held upright by inserting the lower end portion of the upright support column into the insertion groove of the transport base. Thereby, sufficient intensity | strength for storing and holding a transported thing can also be ensured.

  Moreover, according to this invention, it is in the open state without the said cover member between some adjacent support | pillars, This opening part is made into the entrance / exit of the conveyed product accommodated on a conveyance base. In this way, by allowing the transported object to be placed from the side of the transport base, it is possible to store medium-sized or large electronic devices that are heavy and bulky into the transport base and take out from the transport base. It can be done easily.

  In addition, the transported material transport pallet of the present invention includes a lid body that covers an upper end portion of each support column erected on the transport base, and the lid body is placed on the transport base when the pallet is collected. It is used as a lid for covering each tilted column and each folded cover member. In addition, the lid body is formed in a shape that can cover the transport base, and the upper end portion of the support column is supported by inserting the upper end portion of the support column upright on the inner surface end portion. The insertion groove part to be formed is formed.

  Thus, at the time of pallet collection, the transported material transport pallet can be formed into a flat box shape by using it as a cover that covers each support column tilted on the transport base and each folded cover member. As a result, when loading on a truck or the like, stable loading without collapsing is possible even when stacking in multiple stages.

  Further, at the time of transporting the transferred object, the upper end portion of the upright column is inserted and held in the insertion groove portion formed in the inner surface end portion of the lid. Thereby, since the lower end portion is inserted and held in the insertion groove portion provided in the conveyance base, and the upper end portion is inserted and held in the insertion groove portion provided in the lid body, Even if it receives an impact from the outside, it does not fall down easily and it fulfills the role as a support.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 12 show a transported material pallet according to an embodiment of the present invention.

  This transporting material pallet is erected on the conveying base 1 and at each corner of the conveying base 1 and is also provided with four columns 3, 3,. .. and the cover member 6 provided between the adjacent columns 3 and 3 and the upper ends 38, 38... Of the respective columns 3, 3. It is comprised with the cover body 8 to coat | cover.

  In the present embodiment, the transport base 1 is formed in a rectangular shape from wood, resin, or light metal (stainless steel, etc.) having sufficient strength, and each side surface portion 11 has a pair of holes for fork insertion. Portions 12a and 12b are formed. That is, as shown in FIG. 4 (d), a grid-like (cross-girder) groove portion 13 is formed on the bottom surface portion of the conveyance base 1, and an opening to each side surface portion 11 of this groove portion 13. Are fork insertion holes 12a and 12b. In other words, nine legs 14, 14... Arranged in three vertical and horizontal rows are formed on the bottom surface of the conveyance base 1, and a fork is inserted between these legs 14, 14. It becomes the groove part 13 for use.

  On the other hand, the upper surface portion 18 of the transport base 1 is provided with a tilting mechanism portion 40 that supports the vicinity of the lower end portion 31 of the support column 3 so as to be tiltable at each corner portion. FIG. 5 shows a part of the tilting mechanism 40 in an enlarged manner. FIG. 5A is an exploded view, and FIGS. 5B and 5C show a state in which the support column 3 is slidably attached. (D) is a perspective view which shows a mode that a support | pillar tilts.

  The tilting mechanism 40 has a hinge structure in which two rotating plates 42 and 43 can be rotated via a support pin 41 serving as a rotation fulcrum, and one rotating plate 42 is fixed to a screw or the like. The tool 44 is fixed to the upper surface portion 18 of the transport base 1. On the other hand, the other rotation plate 43 is integrally formed with a support body 45 having a triangular prism shape which is erected vertically. The support body 45 has a right-angled isosceles triangle in plan view, and is arranged such that two orthogonal side surfaces 46 and 47 are parallel to the orthogonal side surfaces 11 and 11 of the transport base 1, respectively. Each orthogonal side surface 46, 47 is provided with a screw hole 48 for attaching a fixing tool 49 such as a screw for supporting the column 3.

  On the other hand, the support column 3 is made of a metal such as stainless steel or iron, and is bent to have an L-shaped cross section, and each of the orthogonal side plates 32 and 33 has a vertically long slot 32a at the lower end 31 thereof. , 33a are formed.

  In the column 3 having such a shape, the inner surfaces of the orthogonal two side plates 32 and 33 of the support column 3 are attached to the two orthogonal side surfaces 46 and 47 of the support body 45, and in this state, the fixture 49 is attached to each elongated hole. It is attached to the support body 45 by screwing into the screw holes 48, 48 of the support body 45 through 32a, 33a. At this time, since the screw insertion holes of the side plates 32 and 33 of the support column 3 are formed in the elongated holes 32a and 33a, the support column 3 is provided with the elongated hole 32a as shown in FIGS. , 33a, it is possible to slide in the vertical direction by the length regulated by 33a. However, in order to be slidable, it is necessary not to completely tighten the fixture 49 but to tighten it with a margin. Moreover, in order not to overtighten, the screwing depth of the fixture 49 may be regulated in advance, and no further screwing may be performed. In the present embodiment, a screw is used as the fixture 49, but is not limited to a screw.

  That is, in the sliding mechanism portion described in the claims, the engagement relationship between the fixture 49 screwed into the screw hole 48 of the support body 45 and the elongated holes 32 a and 33 a formed in the side surfaces 32 and 33 of the support column 3. It is constituted by.

  On the other hand, at each corner portion of the upper surface portion 18 of the transport base 1 facing the lower end portion 31 of the support column 3, there are insertion groove portions 19 formed in an L shape in plan view for inserting the lower end portion 31 of the support column 3. Is formed.

  Since the tilting mechanism portion 40 has such a structure, when the transported object is stored, the lower end portion 31 of the upright column 3 is inserted into the insertion groove portion 19 of the transport base 1 (FIG. 5C). The state shown in FIG. 3) makes it possible to firmly hold the column 3 upright. Further, when folding, the upright column 3 is pulled upward, and the lower end 31 of the column 3 is extracted from the insertion groove 19 (the state shown in FIG. 5B). When tilted in the direction of the central part 1, the support column 3 falls smoothly toward the central part of the transport base 1 due to the hinge structure of the tilting mechanism part 40 as shown in FIG. 5 (d). .

  6 (a) and 6 (b), the support columns 3, 3... Provided at each corner of the transport base 1 are completely tilted on the transport base 1 (that is, completely folded). Indicates the state. In the present embodiment, the transport base 1 is formed in a square shape, and each support column 3 tilts toward the center of the transport base 1 (that is, tilts along a diagonal line). A cover member 6 (to be described later) is accommodated in a triangular space S (more precisely, an isosceles triangular shape in plan view) between the tilted columns 3 and 3.

  Here, the support | pillar 3 is formed in the cross-sectional L-shape (that is, it has thickness when it sees from the side). Therefore, in a state where the support column 3 is completely tilted on the upper surface portion 18 of the transport base 1, it becomes higher than the upper surface portion 18 by at least the thickness L1. Therefore, the space S has a height of at least this thickness L1. In FIG. 6B, due to the structure of the tilting mechanism portion 40, the base end side of the support column 3 is slightly higher, and the height from the upper surface portion 18 of the transport base 1 is L2 (> L1). However, the height L2 can be suppressed to the thickness L1 of the support column 3 by providing the tilting mechanism portion 40 in, for example, a recess formed in the upper surface portion 18 of the transport base 1. .

  The cover member 6 is made of a material that is relatively hard and has a flexibility that can be folded along a fold line. The cover member 6 has left and right ends fixed to the side plates of the columns 3 and 3 adjacent to each other over almost the entire length in the height direction, and is formed into a square or a horizontally long rectangle or a vertically long rectangle as a whole. Is formed. However, in this embodiment, it is formed in a horizontally long rectangle.

  A folding line is formed on the cover member 6 so as to be folded into the triangular space S (see FIG. 6A) in accordance with the tilting operation of the adjacent columns 3 and 3.

  FIG. 3 shows the state of this broken line, and is a side view of the cover member 6 viewed from the outside.

  That is, the cover member 6 includes the folding points a1 and b1 near the left and right ends of the lower end edge, and the folding points a2 and b2 at positions slightly away from the horizontal center of the upper end edge. Are formed by two fold lines 71 and 72 crossing in an X shape, and are slightly further outside of the fold points a2 and b2 at the upper edge and the fold points a1 and b1 at the lower edge. Two broken lines 73m and 74m are formed to connect each of the folding points a3 and b3 provided on the side with a straight line.

  The polygonal line 71 is divided into two at the intersection point p, the fold line 71m from the fold point a1 to the intersection point p is a fold line 71mv for the mountain fold or the fold line 71mv from the intersection point p to the fold point a2. . Similarly, the polygonal line 72 is also divided into two at the intersection point p, the fold line 72m from the fold point b1 to the intersection point p is the fold line 72mv for mountain fold or valley fold from the intersection point p to the fold point b2. ing. The broken lines 73m and 74m are both for mountain folding.

  It should be noted that the broken line 71mv and the broken line 72mv are folded in either direction depending on the user's folding method so that when one is for mountain folding, the other is for valley folding.

  The triangular surface (A) formed by the break point a1, the intersection point p, and the break point b1 fits into the triangular space S formed between the tilted columns 3 and 3 ( Isosceles triangle). For the sake of convenience, the triangular surface formed by the break point a2, the intersection point p, and the break point b2 is formed by the plane (B), and the break point a1, the intersection point p, the break point b2, and the break point a3 are formed. The quadrangular surface to be formed is the surface (C), the substantially triangular surface formed by the fold points a3 and b2 and the attachment side to the support column 3 is the surface (D), and the fold points b1 and the intersection point p are folded. A quadrangular surface formed by the points a2 and b3 is a surface (E), and a substantially triangular surface formed by the break points b3, the a2 and the attachment side to the column 3 is a surface (F). And

  Next, a procedure for folding the cover member 6 having the above configuration will be described.

  7 and 8 show a state in the middle of folding the cover member 6 in which the broken lines are formed as described above in accordance with the tilting operation of the respective columns 3, 3,.

  That is, in the state where the lower end portion 31 of the upright column 3 is inserted into the insertion groove portion 19 of the transport base 1 and the column 3 is held upright, the cover member 6 is stretched substantially flush.

  From this state, each of the columns 3, 3... Is pulled upward, the lower end 31 of the column 3 is extracted from the insertion groove 19 (see FIG. 5 (b)), and the column 3 is removed from the carrier base 1 in this state. Tilt down toward the center (see FIGS. 5D and 8).

  As a result, the cover member 6 is folded so that the upper end side of the cover member 6 approaches, and the folding action causes a force in the direction of the arrow x1 to act on the points a2 and b2 as shown in FIG. 7A. As a result, the polygonal lines 71m and 72m are valley-folded, and the polygonal lines 73m and 74m are mountain-folded. That is, the surface (C) and the surface (D) are bent so that they are combined on the back surface side, and the surface (E) and the surface (F) are bent so that they are combined on the back surface side. At this time, in the middle of folding, the folding lines 71mv and 72mv are slightly bent in a mountain fold, and the surface (B) is bent and bent in a U shape at the center.

  In this state, as shown by white arrows in FIG. 7B, when folded one of the folding surfaces (E), (F) so as to overlap the surface (A), As shown in FIG. 7C, the broken line 71mv is folded in a mountain, the folded line 72mv is folded in a valley, and the curved surface (B) returns to a flush state and is attached to the surface (C). Will be.

  Thereafter, when the other folding surfaces (C) and (D) are folded so as to overlap the surface (A) as indicated by white arrows in FIG. As shown, the cover member 6 is folded and stored in a triangular space S formed between the adjacent columns 3 and 3. As described above, since the space S has a height corresponding to the thickness L1 of the support column 3, even if the folded cover member 6 has a certain thickness, the space S is within the thickness L1 of the support column 3. It can fit well.

  On the other hand, when unfolding the cover member 6 folded in this way, the tilted support columns 3, 3. As a result, the cover member 6 is also unfolded naturally as it is caused by the columns 3, 3,.

  In addition, as can be seen from FIGS. 1 and 6 and the like, in this embodiment, the cover member 6 is not provided on one side of the four sides of the transport base 1 and is open. In other words, the open portion 91 is used as a loading / unloading port for a transported article stored on the transport base 1.

  As shown in FIG. 9, the lid body 8 is formed in a shape capable of covering the transport base 1, and each side surface portion 81 has a pair of side surfaces 11 formed on each side surface portion 11. A pair of holes 82a and 82b for fork insertion are formed at the same positions as the holes 12a and 12a.

  Further, L-shaped insertion groove portions 86 are formed in the respective corner portions 84, 84... On the inner surface side of the lid body 8. That is, rectangular projections 85, 85... Are formed at the corners 84, 84... On the inner surface side of the lid 8, and two side surfaces 81, 81 of the projection 85 and the lid 8 facing each other. The L-shaped gap formed between the two is used as the insertion groove 86.

  In other words, the transported material pallet of the present embodiment has a structure in which the upper end portion 38 of the upright column 3 is inserted and held in the insertion groove portion 86 formed on the inner surface end portion of the lid 8 when transporting the transported material. It has become. Thus, the support 3 is inserted and held at the lower end 31 in the insertion groove 19 provided in the transport base 1 and the upper end 38 is inserted and held in the insertion groove 86 provided in the lid 8. Even if it receives an impact from the outside in a state where it is stored and held, it can sufficiently fulfill the role as a support column without falling down easily. In addition, at the time of conveyance, as shown in FIG. 10, the cover body 8 is prevented from being removed by spanning two rubber-like bands 95.

  Further, when the pallet is recovered, the lid body 8 includes the support columns 3, 3... Tilted on the upper surface portion 18 of the transport base 1 and the folded cover members as shown in FIGS. 11 and 12. Is used as a cover for covering 6, 6,..., And two rubber bands 95 that are also used at the time of transportation are spanned and assembled together. As a result, the transported material pallet can be formed into a flat box shape, and stable loading without collapsing is possible even when stacking in multiple stages when loading on a truck or the like.

  In the above embodiment, the tilt direction of the support column 3 is described as a diagonal direction toward the center of the transport base 1. However, when the height of the support column 3 is desired to be increased, the tilt direction of the support column 3 is They may be shifted from each other so as to approach each side of the transport base 1.
