DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a presser frame used for preventing cargoes stacked on a pallet for transport, for example, a load such as a bottle or a can, from being collapsed. The present invention relates to a holding frame used for a transport pallet that allows safe stacking of frames.

[0002]

2. Description of the Related Art Conventionally, in the case of transporting bottles and cans of beer, soft drinks and the like, especially in the case of newly manufactured one-way bottles, the bottles are transported in a multi-tiered manner on a transport pallet. An example of transporting a one-way bottle will be described with reference to FIG. 10. A number of one-way bottles 3 are arranged on a transport pallet 2 having a fork insertion port 1, a cardboard 4 having shape-retaining properties is laid thereon, and a cardboard is further provided. A large number of one-way bottles are arranged on the bottle 4, and the bottles 3 are alternately stacked in a multi-stage manner via the cardboard 4. And
A holding frame 5 having substantially the same size as the transport pallet is placed on the uppermost cardboard 4 and a band 6 is hung over the holding frame 5 and fixed. Finally, a heat-shrinkable film 7 such as a polyethylene film is put on while being fixed with the band 6, and wrapped. In this way, the bottles are transported by stacking the bottles on a transport pallet and packing the entire bottle.

[0003] The position where the band 6 is passed over the holding frame 5 is
Usually, there are three places on the side, near the center of the holding frame and near both ends. Then, the bands 6 are laid so as to be orthogonal to each other on a plane. The band 6 is tightened with a strong force to prevent the collapse of the load. For this, presser frame 5
Must have sufficient compression resistance to withstand tightening, and have permanent deformation resistance that does not deform even when tightened for a long time.

As a known example of such a holding frame, there is a holding frame for pallets described in Japanese Utility Model Laid-Open No. 5-3131. The holding frame is composed of an annular rectangular main frame 6 forming a peripheral portion and a cross-shaped auxiliary frame 7 located inside the main frame 6.
Are provided in a state in which an auxiliary core material 8 using a steel pipe such as carbon steel for machine structure is embedded, and around the four corner-shaped spaces S formed by being surrounded by the frames 6 and 7, respectively. , A mesh-shaped portion 9 having a hole V penetrating vertically. The convex portion C is provided on one side of the mesh portion 9 at the center of the holding frame, and the concave portion E is provided on each side of the convex portion C at two locations. Then, when stacking the pallet holding frames, "If the convex portions C and the concave portions E are engaged without any gap, the stacked holding frames are securely fixed in position. . "

[0005]

In the above-mentioned known holding frame, the positioning at the time of stacking is performed by the engagement between the convex portion C and the concave portion E. Is difficult to engage. When taking out from the stacked state, the upper holding frame is lifted to raise the convex portion C.
Since the engagement state between the recess and the concave portion E must be completely released, the sliding portion cannot be pulled out. For this reason, when stacked high, it is difficult to take out, and there is a problem that work efficiency is reduced.

Further, in the known holding frame, since the auxiliary core material 8 for preventing deformation due to the tightening of the band is a steel pipe, the portion of the band is bent by the tightening for a long time, and the entire side surface is bent. Are deformed in a wavy manner. If it is deformed in a wavy manner, the auxiliary core material 8 is a steel pipe, so that not only does it not return to its original state but also makes it difficult to forcibly restore it even if the tightening is released. Then, the presser frame deformed in a wavy manner is not suitable for reuse. Also, since the auxiliary core 8 is insert-molded, it takes time and labor to attach the auxiliary core to the mold together with the material cost, and the cost of the product is increased as a whole. Furthermore, since the auxiliary core material, which is a steel pipe, is embedded, there is a problem that the entire weight increases and it is difficult to handle.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is possible to reliably position the holding frames when they are stacked, and to easily remove the holding frames. An object of the present invention is to provide a holding frame used for a highly rigid transportation pallet having excellent operability.

[0008]

The present invention has the following configuration to achieve the above object. That is, the holding frame used for the transport pallet according to claim 1 is formed by integrally connecting a cruciform reinforcing plate inside a circular rectangular plate-shaped peripheral frame constituting a peripheral portion, and forming four corners of the peripheral frame. A plurality of fitting ribs protruding from the surface are provided in parallel on one surface of the peripheral frame, and the fitting ribs are inclined with respect to a side surface of the peripheral frame in a plane, and the fitting ribs on surfaces opposite to four corners are provided. A plurality of fitting grooves into which the fitting ribs fit are provided at positions facing the mating ribs,
The width of the fitting groove is formed larger than the width of the fitting rib. Further, the holding frame used for the pallet for transportation according to claim 2 is such that the width of the fitting groove is 1.5 to the width of the fitting rib.
The length of the fitting groove is 1.1 to the length of the fitting rib.
The fitting rib and the fitting groove are inclined at approximately 45 degrees with respect to the side surface, and are disposed in a triangular enlarged portion provided inside the four corners of the peripheral frame. Things.

Further, the holding frame used for the transport pallet according to the third aspect is characterized in that the fitting grooves are provided two more than the number of the fitting ribs. Further, the holding frame used for the transport pallet according to claim 4 is:
The peripheral frame is provided with an outer rib, an inner rib, and an inner rib parallel to these ribs on one surface of the plate body, and an orthogonal rib is provided between the outer rib and the inner rib. A triangular plate body coplanar with the plate body is provided inside the four corners, and a fitting rib slightly projecting from the height of each of the ribs is provided on the triangular plate body; A fitting groove is provided on a surface at a position facing the fitting rib. The holding frame used for the transport pallet according to claim 5 is characterized in that drain holes are respectively formed in a room surrounded by each rib.

[0010]

The positioning is ensured by the fitting rib being fitted into the fitting groove of another laminated holding frame, so that the fitting rib does not slide down easily. The inclined fitting rib and the fitting groove act to move in the center direction, and when pulled out in the side direction, a force acts obliquely in the engagement between the fitting rib and the fitting groove. The engaged state can be easily released. Further, since there is a clearance between the fitting rib and the fitting groove, pulling out is further facilitated in combination with the oblique application of a force.

In the case where the fitting rib and the fitting groove are provided in an enlarged triangular portion provided inside the four corners of the peripheral frame,
When used as a holding frame, the uppermost thick paper is pressed, thereby preventing the holding frame from shifting. By providing the outer peripheral rib, the inner peripheral rib, and the inner rib parallel to these ribs on one surface of the peripheral frame, the band has sufficient strength against the tightening force of the band. In addition, rainwater and the like can be quickly drained by the drain holes formed in the respective rooms surrounded by the ribs.

FIG. 7 is an explanatory view showing a fitting state at the time of stacking, FIG. 7 is an enlarged view in a section taken along line YY in FIG. 1, FIG. It is an expanded sectional view of a frame. The holding frame 10 is formed by integrally connecting a cruciform reinforcing plate 13 inside an annular rectangular plate-like peripheral frame 11 constituting a peripheral portion, and the cruciform reinforcing plate 13 is substantially similar to each side of the peripheral frame 11. Connected at the center. And the reinforcing ribs 14 inside the four corners

6 and a reinforcing rib 18 connecting the corners of the intersections of the reinforcing plates 13 to reinforce the connecting portion and to provide four substantially octagonal through holes 15 therein.

The peripheral frame 11 has an outer peripheral rib 17 and an inner peripheral rib 19 provided on one surface of an annular plate body 12.
A parallel inner rib 20 is provided between the inner rib 7 and the inner peripheral rib 19. The parallel inner ribs 20 are connected to the oblique ribs 21 which cross the outer peripheral ribs 17 at approximately 45 degrees at four corners. The outer peripheral rib 17, the inner peripheral rib 19, the inner rib 20, and the oblique rib 21 are formed at substantially the same height in the vertical direction. Since the outer rib 17, the inner rib 19, and the inner rib 20 are orthogonal to the band to be tightened, they are sufficiently reinforced for the pressing force to be tightened and prevent deformation due to bending.

Further, the peripheral rib 11 is provided on the peripheral frame 11.
7. Orthogonal rib 2 orthogonal to inner peripheral rib 19 and inner rib 20
3 are provided. The interval between the orthogonal ribs 23 is narrowed at the center portion and the end portion where the peripheral frame 11 is hooked. That is, in the range of the connecting portion B between the adjacent portion A and the reinforcing portion 13 at the four corners, the interval is provided to be small. Thus, the strength against the tightening force is further improved by reducing the interval between the orthogonal ribs 23. And
In each of the chambers 25 which are surrounded by the ribs and open at the upper surface, small holes 27 for draining are formed to penetrate vertically.
The smaller the water drain hole is, the better the water drain hole can maintain strength.

Small ribs 56 are provided between the orthogonal ribs 23 to connect between the outer ribs 17 and the inner ribs 20 adjacent to the outer ribs 17. Each of the small chambers having an open upper surface surrounded by the orthogonal ribs 23, the outer peripheral ribs 17, the inner ribs 20, and the small ribs 56 is provided with small holes for draining vertically therethrough. By providing the small rib 56, the strength of the peripheral portion can be further improved. Note that a plurality of small ribs 56 may be provided between each of the orthogonal ribs 23, and the small ribs 56 are not necessarily required to be parallel to the orthogonal ribs 23.

Next, a positioning structure which is a feature of the present invention will be described. The positioning structure fixes the positions of the upper and lower holding frames when the holding frames 10 are stacked one on top of the other, and prevents undesired sliding. Inner circumferential rib 19 of peripheral frame 11
At the four corners, the plate 12 is provided inside the reinforcing ribs 14 connecting the corners.
And a triangular plate body 50, which is a triangular enlarged portion continuous with
On the upper surface of the triangular plate body 50, that is, on the side of the inner peripheral rib 19, a fitting rib 51 slightly higher than the height of the inner peripheral rib 19 is provided so as to protrude. The fitting ribs 51 are inclined with respect to the inner circumferential ribs 19 similarly to the oblique ribs 21, and a plurality of fitting ribs are provided at appropriate intervals. In the embodiment, the inclination of the fitting rib is approximately 4
5 degrees, and five fitting ribs are formed. And since it protrudes in the range of the triangular plate body 50, the central part is long and it is formed short gradually toward both sides. Small holes 53 for draining water are formed between the fitting ribs 51 (see FIG. 4).

On the surface opposite to the fitting rib 51, there is provided a fitting groove 55 into which the fitting rib 51 is fitted when being stacked (see FIG. 5). The fitting groove 55 is larger than the fitting rib 51 and is formed two more than the fitting rib. That is, a width _{T 1} and the width of the fitting groove when the _{T 2 T} 1 _{<T 2} of the fitting ribs 51, the _{T 1} 4 to 6
mm, and _{T 2} and 8 to 12 mm, preferably at _{T 2 T 1}
About twice as large as The length of the fitting groove 55 is the same as that of the fitting rib 5.
It is formed to have a length longer than 1 and 1.1 to 1.3 times, preferably about 1.2 times. That is, as shown by a dashed line in FIG. 2, the fitting groove 55 protrudes from the triangular plate 50 and the plate 1
2 and is open at the end on the reinforcing rib 14 side, and communicates with each other at the small drainage hole 53. The protruding height of the fitting rib 51 and the depth dimension of the fitting groove 55 are substantially the same, each being 0.5 to 1.5 mm, preferably 0.8 to 1.2 mm.
And The number of the fitting grooves 55 as a whole is two more than the number of the fitting ribs 51, and the three central grooves are formed to have the same size. The reason why the number of fitting grooves is increased and the center groove is formed to have the same size is to enable fitting and positioning even if one groove is shifted from the center groove.

In the case where the positioning structure according to the above configuration is provided, when the holding frames are stacked, the upper fitting ribs 51 are fitted into the lower fitting grooves 55 and positioned, so that the positions are cleanly fixed. In addition, stacking can be performed safely without slipping down easily due to mutual fitting. Further, the fitting rib 51 and the fitting groove 55 are formed so as to be inclined with respect to the side surface, and there is some clearance between them, so that they can be fixed in position while sliding and then pulled out. it can. That is, when stacking or taking out, the sliding is performed in parallel with the side surface.
1 and the fitting groove 55 are fitted or pulled out obliquely. Therefore, the force of engagement between the two acts so as to shift obliquely without crossing at right angles. In addition, since there is some clearance between the two, there is an initial movement in the fitting groove 55, and the engagement state can be easily released with a small pressing force. In this manner, the stacked holding frames can be reliably fixed in position, and the engagement state can be easily released, so that the holding frames can be taken out with a small force.
In the case of stacking, the fitting groove 55 is
May be the lower surface. In this case, the fitting rib 51 of the lower holding frame is fitted into the upper fitting groove 55 to be positioned.

In the above embodiment, a triangular enlarged portion having a straight inner surface is provided inside the four corners of the peripheral frame 11, and the fitting rib 51 and the fitting groove 55 are provided in the triangular enlarged portion. It is not always necessary to provide the triangular enlarged portion, and it may be provided at the four corners of the peripheral frame 11 or near the four corners.
In the case where the triangular enlarged portion is provided, the four corners are reinforced and pressed by the band tightened when used as the holding frame, so that the top cardboard is pressed to prevent the holding frame from shifting. Further, the peripheral frame is not limited to the one provided with the ribs vertically and horizontally as in the embodiment, but may be a plate-like body having smooth both surfaces.

Another configuration of the peripheral frame 11 will now be described. As shown in FIGS.
The corners between the outer surface 29 and the upper surface 30 and the lower surface 31 are tapered surfaces 33 and 35. In particular, since the upper surface 30 and the outer surface 29 to which the band abuts are made continuous by the tapered surface 33, the adaptation of the band is improved, so that the tightening is easy, the tightening force is maintained, and the band is prevented from shifting. The tapered surfaces 33 and 35 include not only a completely straight surface but also a slightly curved surface. In addition, since the tapered surface 35 is a lower side when used, it can be omitted as appropriate.

A part of the outer surface 29 of the outer peripheral rib 17 is provided with a recess 36 which is slightly cut out. The concave portion 36 is provided between the banded portions A and B, and one concave portion 36 is provided on at least two outer surfaces 29 facing each other. By coating the concave portion 36 with an appropriate color, the concave portion 36 can be used as a mark indicating the owner, or as a mark of the number of stages in the case of stacking in multiple stages. By being recessed from the outer side surface 29 and being provided at a position deviated from the band hanging portion, it is possible to prevent rubbing.

Next, the cross reinforcing plate 13 will be described. Similar to the peripheral frame 11, the cross-shaped reinforcing plate 13 has an edge rib 37 on the upper surface of the cross-shaped plate body 38 and the edge rib 37.
Inner rib 39 parallel to the end rib 37 and the inner rib 3

Reinforcing ribs 16 are provided at the corners of the connecting portion with the reinforcing member 1, and reinforcing ribs 18 are provided at the corners of the intersections at the center to reinforce each. As described above, the strength of the connecting portion can be increased by the reinforcing ribs 16 and the reinforcing ribs 18 together with the reinforcing ribs 14 inside the four corners. The reinforcing ribs 16 and the reinforcing ribs 18 are desirably provided on the upper surface of a triangular plate body 45 which is flush with the plate bodies 12 and 36, and a small hole 47 for draining water is desirably formed.

[0023]

As is clear from the above, according to the present invention, the following specific effects can be obtained. That is, since the fitting ribs and the fitting grooves are provided so as to be inclined with respect to the side surfaces, the position can be reliably fixed at the time of stacking, and it can be easily taken out with a small force. In addition, since the removal is performed with a small force, the lower holding frame is not displaced or slipped. In addition, when the fitting rib and the fitting groove are inclined at approximately 45 degrees with respect to the side surface, the direction at the time of stacking is not limited. Further, the number of the fitting grooves is formed two more than that of the fitting rib, and the size of the three grooves at the central portion is formed in the same manner. Position. In addition, the provision of the inner triangular enlarged portions at the four corners of the peripheral frame provides reinforcement, and can be positioned below the band for tightening the fitting rib and the fitting groove.
In addition, since the peripheral frame is provided with ribs running vertically and horizontally on one surface of the plate body, bending due to band tightening can be prevented, and a lightweight and robust holding frame can be obtained.
