The present invention relates to a presser used for preventing collapse by loads of cargo, such as bottles or cans, which are multi-stage loaded on a transport pallet.

Conventionally, in the case of conveying bottles and cans such as beer and soft drinks, especially newly prepared disposable bottles, they are stacked and transported in multiple stages on a transport pallet from a bottle manufacturing plant to a beverage manufacturing company. Referring to the example of transporting a disposable bottle based on FIG. 11, a plurality of disposable bottles 3 are arranged on a transport pallet 2 having a fork guide hole 1, and there is a shape retention thereon. The thick paper (4) is inserted into a plurality of disposable bottles are arranged in sequence, thus stacking the bottles (3) in multiple stages alternately through the thick paper (4). Then, a presser 5 of substantially the same size as the pallet for transport is placed on the uppermost thick paper 4, and the band 6 is fixed to the presser 5 over. Finally, the heat shrinkable film 7, such as a polyethylene film, is covered and wound in the state fixed with the band 6. In this way, the bottles are stacked in multiple stages on a transport pallet and packaged and transported in their entirety.

The position where the band 6 hangs on the presser 5 is typically three points on the side near the center and both ends of the presser, and in the plane they are crossed so that they are perpendicular to each other. The band 6 is fastened with a strong force in order to prevent collapse by the load. Therefore, the pressing frame 5 must have compression resistance so as to withstand the fastening sufficiently, and have a deformation resistance that does not deform even for a long time fastening.

As a known example of such a presser, there is a presser for pallets described in Japanese Utility Model Publication No. 5-3131. The pressing frame is a state in which auxiliary cores made of steel pipes, such as mechanical structural carbon steel, are embedded in an annular rectangular main frame forming a periphery and a cross auxiliary frame located therein. Four angular spaces S are provided, and a mesh-shaped portion having holes V penetrating in the vertical direction is provided in the frame. In addition, a protruding shape is provided over the entire circumference at a central position of the outer surface of the main frame, and auxiliary ribs for the protruding shape are provided at appropriate intervals in the longitudinal direction of the protruding shape. In addition, one side of the said net-shaped part of a presser center part is provided with the convex part C which protrudes from the surface in the said thickness direction, and two concave parts E are provided in the opposite side of this convex part C, respectively. It is. When stacking the pallet presser, if the convex portion C and the recess portion E are engaged without a gap, the presser stacks of the stages can be accurately positioned and stacked.

In the above-mentioned well-known presser, since the auxiliary core material is embedded in order to prevent deformation by fastening of the band, the main frame is not crushed or destroyed by the fastening force. However, since the auxiliary core material is a steel pipe, it is bent at a portion of the band by long time tightening, and the whole side is deformed into a wave shape at the side surface. If the wave is deformed, the auxiliary core is a steel pipe, even if it is released, not only to be restored to its original state, but also to be forcibly restored. And, the wedge deformed into the wave shape is not suitable for reuse. In addition, in order to insert-mold the auxiliary core material, the trouble of attaching the auxiliary core material to the mold together with the material cost is generated and the cost of the product as a whole is increased. In addition, since the auxiliary core, which is a steel pipe, is embedded, the total weight is increased, and thus handling is difficult.

In addition, in the above-mentioned well-known press frame, when stacking a stage, since a position is determined by the engagement of the convex part C and the recessed part E, it is difficult to reliably engage both when stacking a stage. In addition, when the step is taken out from the stacked state, the upper presser must be lifted to completely release the engagement state between the convex part C and the concave part E. You can't slide it out. Therefore, when the steps are piled high, it is difficult to lift them, so that it is difficult to take them out, and there is a problem in that work efficiency is lowered.

This invention is made | formed in view of such a situation, and an object of this invention is to provide the press box mentioned later. That is, the presser used in the transport pallet according to the present invention is light in weight, easy to handle, has a high resistance to deformation, and has high rigidity, and when the steps are stacked, the pressers slide and fall. Overlapping so that it can be easily taken out of the stacking presses.

The present invention is configured as follows to achieve the above object. That is, the pressing frame used in the shipping pallet according to claim 1 is integrally connected to the cross-shaped reinforcement plate inside the plate-shaped peripheral frame constituting the peripheral portion, and the outer circumferential rib, the inner circumferential rib and one side of the peripheral frame.

Further, the press frame used in the coal pellets according to claims 4 and 8 provides a small rib between the center portion of the peripheral frame and the orthogonal rib at the end, and the small rib is the outer rib described above. And an inner rib adjacent to the outer rib.

In addition, the pressing frame used for the transportation pallet concerning Claim 5 connects a cross reinforcement board integrally in the inside of the annular rectangular plate-shaped peripheral frame which comprises a peripheral part, and the four corners of one side of this peripheral frame are integrated. A plurality of fitting ribs protruding from the surface and inclined with respect to the side of the peripheral frame are provided in parallel with each other, and the plurality of fitting ribs are fitted at positions opposite to the fitting ribs on opposite surfaces of the four corner portions. The fitting groove is provided, and the width of the fitting groove is formed to be larger than the width of the fitting rib.

Moreover, the press frame used for the conveyance pallet of Claim 6 makes the width of a fitting groove 1.5 to 3 times the width of a fitting rib, and the length of a fitting groove is 1.1-1.3 of the length of a fitting rib. The fitting ribs and the fitting grooves are inclined at approximately 45 ° with respect to the side of the peripheral frame, and are provided in a triangular enlarged portion formed inside the four corners of the peripheral frame.

The outer periphery rib, the inner periphery rib, and the inner rib parallel to these ribs provided on one side of the above-described peripheral frame have sufficient strength against the tightening force of the band. In addition, since each of the compartments surrounded by the ribs is drilled with drainage holes, rainwater and the like can be drained quickly. In addition, since the outer surface and the upper surface of the outer circumferential rib are continuous by the tapered surface, the wearability of the band is improved and the fastening is easy, and the shift of the band is prevented. Since the octagonal through-holes were formed by installing the reinforcing ribs connecting the corners in the four corners of the peripheral frame and the connecting portion of the peripheral frame and the cross-shaped reinforcement plate, the four corners and the connecting portion were reinforced so that the entire rigidity was pressed. You can do it.

In addition, according to claim 5, the fitting ribs are reliably positioned by being fitted into the fitting grooves of the other pressing frames in which the fitting ribs are stacked, so that the sliding does not become difficult. Incidentally, the inclined fitting ribs and the fitting grooves act to move the stacked pressing frames in the direction of the center of each other, and when they are pulled out in the lateral direction, the inclined fitting ribs and the fitting grooves are inclined with respect to the engagement of the fitting ribs and the fitting grooves. Because of the force, the engagement can be easily released. In addition, since there is a gap between the fitting rib and the fitting groove, the force acts obliquely and the removal is further easier.

Moreover, the inclination angle of 45 degrees of a fitting rib and a fitting groove can slide from both front, back, left, and right of Claim. In addition, when the fitting rib and the fitting groove are provided inside the four corners of the peripheral frame, the triangular enlargement portion presses the thick paper at the uppermost end to prevent the deviation of the pressing frame itself.

Further, according to claim 7, even if one deviates from the center groove, it is fitted and positioned.

According to still another preferred embodiment of the present invention, the press mold can be molded integrally by using a synthetic resin.

Next, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, the pressing frame 10 is formed by integrally connecting the cross-shaped reinforcement plate 13 to the inside of the annular rectangular plate-shaped peripheral frame 11 constituting the periphery, the cross-shaped reinforcement plate 13 It is connected in the substantially center part of each side of the periphery 11 mentioned above.

The outer circumferential rib 17, the inner circumferential rib 19, the inner rib 20, and the inclined rib 21 are formed at substantially the same height in the vertical direction. Since the outer circumferential rib 17, the inner circumferential rib 19, and the inner rib 20 are orthogonal to the fastening bands, they are sufficiently reinforced against the clamping force to be fastened to prevent deformation due to bending.

Moreover, the orthogonal rib 23 orthogonal to the outer periphery rib 17, the inner periphery rib 19, and the inner rib 20 is provided in one surface of the periphery frame 11. The orthogonal rib 23 has narrow space | interval at the center part and the edge part (four corner parts) which the band of the periphery frame 11 hang over. That is, as shown in FIG. 1, it is provided in narrow space | interval in the range of the adjacent part A of the four corner parts, and the connection part B of the reinforcement part 13.

The clamping force is not deformed.

Between each orthogonal rib 23, the small rib 56 which connects between the said outer peripheral rib 17 and the inner rib 20 adjacent to this outer peripheral rib 17 is provided (refer FIG. 4). A small drainage hole 27 penetrating up and down is drilled in each of the small compartments in which the upper surface surrounded by the orthogonal rib 23, the outer circumferential rib 17, the inner rib 20, and the small rib 56 is opened. . By providing the small ribs 56 described above, the strength of the edge portion can be further improved. In addition, you may provide more than one small rib 56 between each orthogonal rib 23, and it is not necessarily parallel to the orthogonal rib 23. As shown in FIG.

As shown in FIGS. 6 and 7, the angular portions of the outer surface 29 and the upper surface 30 and the lower surface 31 of the outer circumferential rib 17 are tapered surfaces 33 and 35. In particular, since the upper surface 30 and the outer surface 29 on which the band abuts are continuous by the tapered surface 33 to improve the wearability of the band, the fastening force is easily maintained and the fastening force is maintained, thereby preventing the band from shifting. The tapered surfaces 33 and 35 may be completely straight surfaces or may be slightly curved surfaces.

In addition, a part of the outer surface 29 of the outer circumferential rib 17 is provided with a recess 36 formed by cutting slightly (see FIGS. 1 to 4). This recessed part 36 is provided between the band hanger part A and the band hanger part B, and one or more is provided in the outer side 29 of two parallel sides which oppose. The concave portion 36 may be coated with a suitable color, and the painting may be a mark indicating the owner, or may be a mark for counting the number of stages when the presses are stacked in multiple stages. By making it concave from the outer surface 29 and providing it in the position which removed | deviated from the band hanger part, peeling off of a coating can be prevented.

In the cross-shaped reinforcement plate 13, similarly to the peripheral frame 11, the upper surface of the cross-shaped plate 38 and the end rim rib 37, and the inner rib 39 parallel to the end rim 37 And orthogonal ribs 40 orthogonal to the end border ribs 37 and the inner ribs 39. In addition, a small drainage hole 43 penetrating up and down is drilled in each compartment 41 surrounded by each rib and having an open upper surface. The reinforcing ribs 16 are provided at the corners of the connecting portion with the peripheral frame 11, and the reinforcing ribs 18 are provided at the corners of the cross section of the center to reinforce each. Thus, by providing the reinforcing ribs 16 and the reinforcing ribs 18 together with the reinforcing ribs 14 inside the four corner portions, the strength of the connecting portion can be increased. The reinforcing rib 16 and the reinforcing rib 18 are preferably provided on the upper surface of the triangular plate 45 having the same plane as the plate bodies 12 and 38, and drill a small drain hole 47. Next, a positioning structure which is another feature of the present invention will be described based on FIG. 7 to FIG.

The positioning structure is to fix the upper and lower press frames while positioning the press frames 10 in the vertical direction, and to prevent the slide from falling off. Four corners of the inner circumferential rib 19 of the peripheral frame 11 are provided with a triangular plate body 45, which is a triangular enlarged portion that is continuous with the plate body 12, inside the reinforcing ribs 14 connecting the edges. The fitting rib 51 which is slightly higher than the height of this inner circumferential rib 19 is protruded and provided in the upper surface of 45), ie, the inner circumferential rib 19 side. The fitting ribs 51 are inclined with respect to the inner circumferential rib 19 like the inclined ribs 21, and a plurality of fitting ribs 51 are provided at protruding intervals. In the embodiment, the inclination of the fitting rib is approximately 45 degrees, and five fitting ribs are formed. And since it is provided so that it may protrude in the range of the triangular plate body 45, the center part is long and is formed gradually shorter toward both sides. A small drain hole 53 is drilled between each of the fitting ribs 51 (see FIG. 8).

On the surface corresponding to the fitting rib 51 opposite the triangular plate body 45, a fitting groove 55 into which the fitting rib 51 is fitted when stacked is provided (see Fig. 9). The above-described fitting groove 55 is larger than the fitting rib 51, and two more than the fitting rib are formed. That is, as shown in FIG. 7, when the width of the fitting rib 51 is T ₁ and the width of the fitting groove is T ₂ , T ₁ (T ₂ , T ₁ is ₄ to 6 mm, T _2). Is set to 8 to 12 mm, and preferably T ₂ is about twice that of T _1. The length of the fitting groove 55 is 1.1 to 1.3 times, preferably about 1.2, longer than the fitting rib 51. In other words, as shown by the dashed-dotted line in FIG. 2, the fitting groove 55 protrudes from the triangular plate body 45 to reach the plate body 12, and the reinforcing ribs ( 14 is open at the end, and communicates with each other in the small drain hole 53. The protruding height of the fitting rib 51 and the depth dimension of the fitting groove 55 are almost the same. And 0.5 to 1.5 mm, preferably 0.8 to 1.2 mm, respectively, and two of these fitting grooves 55 are formed in total more than the number of the fitting ribs 51 as a whole. The three grooves of the portion are formed in the same size.In this way, the number of the fitting grooves is increased and the grooves of the center portion are formed in the same size so that the fitting ribs 51 fit even if one groove is separated from the center groove. It is to be able to position the position.

In the case where the positioning structure according to the above-described configuration is provided, when the press frames are stacked, the fitting ribs 51 of the upper press frames are fitted into the fitting grooves 55 of the lower press frames so that they are positioned. Aligned and fixed. In addition, the slides can be stacked safely without being difficult to slide by the mutual fit. In addition, the fitting rib 51 and the fitting groove 55 are formed to be inclined at an angle with respect to the side surface of the peripheral frame 11, and because there are some gaps between the two, the position fixing and taking out while sliding Can be.

In other words, when stacked or taken out, the fitting rib 51 and the fitting groove 55 are fitted or drawn out from the inclined direction because they slide parallel to the side surface. Therefore, the forces that engage both sides act so as to deviate obliquely without being orthogonal. 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 by the small pressing force. In this way, it is possible to reliably fix the stacked presses with each other, and at the same time, it is easy to release the engagement state, so that it can be pulled out with a small force.

In addition, when stacking up and down, the fitting groove 55 may be made into the lower surface as opposed to the above-mentioned, In this case, the fitting rib 51 of the presser of the lower end is fitted to the fitting groove 55 of the presser of the upper board. Is fitted and positioned.

In addition, in the above-described embodiment, a triangular enlargement portion 45 having a straight surface on the inner surface of the four corners of the peripheral frame 11 is provided, and the fitting rib 51 and the fitting rib 51 are fitted to the triangular enlargement portion 45. Although the fitting groove 55 is provided, it is not necessary to necessarily provide the triangular enlargement part 45, and you may provide in the four corner part or four corner part vicinity of the periphery frame 11. As shown in FIG. In the case where the triangular enlarged portion 45 is provided, the four corners are reinforced, and when used as a presser, they are suppressed by the fastening band, so that the uppermost thick paper is pressed to prevent misalignment of the presser.

In addition, since the drainage hole is drilled in the compartment surrounded by the ribs, rainwater or the like is immediately drained to prevent contamination. In addition, since the outer surface and the upper surface of the outer circumferential rib are continuous by the tapered surface, the wearability of the fastening band can be improved, the fastening force can be increased, and the shift of the band can be prevented. Moreover, by making an inside octagonal through hole, four corner parts and a connection part are reinforced, and the whole can be made into a highly rigid pressing frame. In addition, since the space | interval of orthogonal rib was narrowed in the center part and the edge part of each edge | side which a band abuts in the press frame which concerns on Claim 2, the intensity | strength of the part fastened by a band can be improved.
