Description

  The present invention relates to a metal pallet, an upper frame member, a corner angle, and a packing structure using these, for example, when packing a sheet or longitudinal axis coil, which is a product of an aluminum alloy plate.

  For example, as a product made of an aluminum alloy plate, there are a coil product rolled up in a coil shape (hereinafter simply referred to as a coil) and a laminate of cut sheet-like sheet products (hereinafter simply referred to as a sheet). The vertical axis, that is, the winding axis is oriented vertically, and the horizontal axis, that is, the winding axis, is oriented horizontally.

By the way, in order to pack the sheet or the coil of the vertical axis, it is necessary to place it on a pallet having a horizontal placement surface, and to fix it firmly with a packaging band. If the product is displaced on the pallet, the product itself is damaged and the product value is lowered.
In particular, the size of the coil has been increased, and in the case of an aluminum alloy coil, for example, a product exceeding 10 tons is packaged and transported.

A device for stably packing a sheet or a coil placed on such a horizontal placement surface has been made so far. However, there is still room for improvement in packing parts such as pallets, and further improvement is required.
Examples of conventional metal pallets include Patent Documents 1 and 2.

  The present invention has been made in view of such conventional problems. The metal pallet, the upper frame member, the corner angle, and the packaging, which can suppress the load slip compared to the conventional art and can stabilize the packaging state. It is intended to provide a structure.

The present invention includes a metal mounting plate portion having a mounting surface on which a product composed of a sheet or a coil of a vertical axis is mounted, and a plurality of metal members laid parallel to the lower surface of the mounting plate portion. A metal pallet provided with a band guide portion having an insertion hole through which a packaging band is inserted, or in the vicinity of the leg portion, and
Using an elongate main body portion made of an aluminum alloy hollow extruded shape member and an upper frame member made of a side wall member made of an aluminum alloy plate welded so as to close both longitudinal ends of the main body portion ,
Place the product consisting of the sheet or the coil of the vertical axis on the mounting plate part in the metal pallet,
Place the upper frame member on the product,
The packaging structure is characterized in that a packaging band through which the band guide portion of the metal pallet is inserted is tightened through the upper surface of the upper frame member (Claim 1) .

  As described above, the metal pallet of the present invention is provided with a band guide portion having an insertion hole through which the packaging band is inserted in the leg portion or in the vicinity thereof. Thereby, the fastening operation | work by the band for packaging used when packing the product mounted in the said metal pallets is made easier than before, and the packing state after clamping can be stabilized.

That is, when the product is fixed on the pallet using the packaging band, the product is turned from the back of the pallet so as to surround the side surface and the upper side of the product, and is fastened and fixed at a predetermined position.
Conventionally, although the packaging band is disposed at a certain position, there is no pallet having the band guide portion as described above. For this reason, conventionally, the operation of aligning the packaging band is relatively complicated at the time of tightening, and for example, the operation of re-adjusting the fastening position of the packaging band is also performed before the final tightening. Further, when a heavy product is transported, stress more than expected is imparted to the product, so it cannot be said that the fastening position of the packaging band does not shift during transport at all.

  On the other hand, in the present invention, the band guide portion is provided as described above. Therefore, the placement position of the packaging band can be easily determined by passing the packaging band through the insertion hole of the band guide portion. Further, even if the fastened packaging band is displaced, the movement is prevented by the band guide portion, so there is no fear that the packaging band is displaced.

  As described above, when the metal pallet of the present invention is used, by having the band guide portion, the tightening operation of the packaging band is facilitated and the placement position of the packaging band is improved. It is possible to suppress the load deviation more and to stabilize the packing state.

As described above, the upper frame member is mainly composed of a long main body made of a hollow extruded shape made of an aluminum alloy. Therefore, it is very lightweight and can facilitate the packing work. Moreover, the side wall member which consists of an aluminum alloy plate is welded to the both ends of the said main-body part. Therefore, even if the packaging band is strongly tightened through the upper surface, the hollow portion of the main body can be prevented from being deformed due to the presence of the side wall member. Therefore, the packaging band can be tightened with a strong tightening force that stabilizes the package appearance.
Accordingly, by using the above-described upper frame member, it is possible to suppress the load displacement, it can be stabilized packed state.

  The corner angle is composed of two side plate portions arranged at right angles so as to have an L-shaped cross section and an upper plate portion arranged at the upper end. Therefore, the corner angle can be easily disposed on the side corner of a product that is stacked on a pallet and has an overall shape of a rectangular parallelepiped. That is, the two side plate portions of the corner angle are brought into contact with the two side surfaces sandwiching the side surface corner portion of the product, and the upper plate portion is brought into contact with the upper surface of the product, so that the corner angle is exactly the side surface of the product. It arrange | positions in the state contact | abutted to the corner | angular part.

In this state, the packaging band can be placed and fastened vertically or horizontally so as to pass over the corner angle, and the packaging can be fixed without damaging the product.
Moreover, if this corner angle is used, it can prevent that the laminated | stacked sheet | seat product slip | deviates, and can obtain the more stable packing state.

The packaging band used in the present invention includes, for example, an iron (carbon steel) band called a band iron or a resin band called a PP (polypropylene) band, each having a thickness of 0.4 to 1.5 mm and a width. 7-35 mm strip shape. The fixing can be performed using a special tool using a metal sealing material.

Further, the band guide part of the metal pallet is most preferably provided along the entire back surface of the mounting plate part, but the above-described effects can be obtained even if it is provided only in part.
The band guide part is preferably provided in parallel with the leg part. In this case, the arrangement of the band guide portion is very easy because both are parallel. In this case, as described later, the band guide part may be provided inside the leg part or may be provided separately from the leg part.
Further, the band guide part can be provided in a direction perpendicular to the leg part.

Further, a bending fulcrum portion having an arcuate surface having a radius of curvature of 3 mm or more is disposed on the opening end portion of the insertion hole in the band guide portion or on an extension thereof, and the packaging inserted through the insertion hole. It is preferable that the working band is configured to be bent along the bending fulcrum ( claim 8 ).

In this case, due to the presence of the bending fulcrum portion, the radius of curvature for bending the packaging band can be increased, and the damage to the packaging band is reduced. It becomes slippery. Therefore, a stronger and more stable packing state can be obtained.
When the curvature radius of the bending fulcrum portion is less than 3 mm, the above-described effects may not be sufficiently obtained.

Further, the band guide portion is configured by the insertion hole provided over the entire length inside the leg portion, and the bending fulcrum portion is an upper side portion of the opening end portion of the insertion hole on both side surfaces of the leg portion. ( Claim 9 ).
That is, it is preferable that the band guide portion is constituted by the insertion hole provided over the entire length inside the leg portion. Thereby, it is not necessary to provide a band guide part separately from the leg part, and the structure can be simplified. Moreover, the operation | work which lets a packaging band pass to the back surface of a mounting base can be made very easy by providing the said insertion hole in the leg part full length.

Further, the side surfaces of both ends of the leg portion is preferably a side cushioning material for absorbing shock is provided (claim 10). In this case, when a plurality of products packed using the metal pallet are placed side by side, it is possible to prevent a problem that the metal legs collide and deform. In addition, when the product on the pallet is a coil, when the work of reversing the axis of the coil from the vertical axis state to the horizontal axis state is performed, the pallet moves downward by its own weight and collides with the reversing machine, etc. It is possible to reduce the impact and reduce the impact sound. In particular, in the case of a conventional wooden pallet, the pallet itself has a function of absorbing an impact. However, when the pallet is made of metal as in the present invention, the use of the side cushioning material is very effective. In particular, when the band guide portion is provided on the leg portion, the wrapping band passing through the side surface of the leg portion can be prevented from being damaged.
As the side cushioning material, for example, a rubber plate, a fiber board, a plastic plate, a hard foam material or the like can be applied.

Further, the bottom surface of the leg portion is preferably a bottom cushioning material for absorbing shock is provided (claim 11). In this case, when the metal pallet is lifted and lowered, it is possible to prevent problems such as collision with the floor surface or truck bed and damage to these. In particular, in the case of a conventional wooden pallet, the pallet itself has a function of absorbing an impact. However, when the pallet is made of metal as in the present invention, the use of the bottom cushioning material is very effective.
Since the bottom cushioning material is always subjected to the load of the product, it is preferable to apply, for example, a plastic square material having excellent load resistance and wear resistance.

Further, the mounting surface on the upper mounting plate portion preferably its entire surface such that communication with the back surface is cut off is formed on substantially connected tabular (aspect 12).
Problems with conventional wooden pallets include mold on the timber and deterioration of the timber itself, resulting in insufficient durability. However, as described above, the mounting plate and legs are made of metal. It can be generally solved by making it. However, the problem of pests sticking to the product or storing dirt when stored in a packaged state cannot be solved simply by changing the material from wood to metal. In particular, in the packaging of aluminum alloy sheet products used as materials for beverage cans and the like, the invasion of pests and dirt becomes a major problem, and thus the occurrence of problems has been suppressed by various environmental measures and management systems.

By the way, usually, the upper part of the pallet is often packed tightly, so most of the pests and dirt enter from the ground through the part that communicates from the back to the surface of the pallet mounting plate. It is.
On the other hand, from the viewpoint of weight reduction, conventional wooden pallets and metal are usually provided with a communicating portion in which the mounting plate portion is shaped like a cocoon and the front and back communicate with each other, particularly for packing sheets or coils. The pallet has at least a part of the front and back communication portions.

  On the other hand, as described above, the upper mounting surface of the above-described mounting plate portion is formed into a flat plate shape whose entire surface is substantially connected so that the communication state with the back surface is blocked. The surface can reliably prevent dirt and insects from passing from the back surface to the front surface of the mounting plate portion. That is, it is possible to take measures against invasion of dirt and insects by the pallet structure itself without relying on environmental measures or management systems.

Moreover, it is preferable that the above-mentioned mounting plate part is comprised by the bone part comprised combining the some metal structural material, and the skin part which covers the upper surface whole surface of this bone part ( Claim 13 ). In this case, strength can be maintained by the bone part, and a mounting surface without a gap can be formed by the skin part, and measures such as weight reduction and insect prevention can be performed simultaneously.
In addition to the structure using the above-mentioned skin part without the sheet-like hole, for example, a plurality of planar parts of the shape member are arranged facing the upper surface as the structure for blocking the communication state with the back surface on the placement surface. A structure in which the contact portion is welded on the front side or the back side may be employed.

Further, the skin portion is preferably made of an aluminum alloy plate (claim 14). Since the aluminum alloy plate has the characteristics of durability and light weight, it is very suitable as the skin portion.
In addition, the said skin part does not necessarily need to be a metal, and it is also possible to apply the resin material etc. which were excellent in durability.

The surface of the skin portion, it is preferable that is arranged anti-slip sheet (claim 15). In this case, it is possible to prevent the product arranged on the mounting plate part from slipping and shifting, and a more stable packing state can be obtained.
As the anti-slip sheet, for example, a rubber sheet can be applied.

Further, the metal pallet is a coil dedicated pallet placed in a coil on the vertical axis, the shape of the upper mounting plate portion is preferably vertical dimension and the horizontal dimension is substantially the same (claim 6 ). In this case, a stable packaging state suitable for the outer shape of the coil can be obtained. And when arranging two or more horizontally, an occupation space can be minimized.

Further, the upper mounting plate portion, it is preferable that is provided with insertion holes for upright positioning member for positioning of the inner diameter of the coil in the central portion (claim 7). In this case, for example, when placing a relatively easy-to-move coil whose width dimension is smaller than the outer shape, it is possible to further enhance the prevention of load deviation. As the positioning member, members having various structures can be used as long as they support the inner diameter of the coil mounted on the mounting plate portion.

Further, as the insertion hole, it is preferable to adopt a bottomed hole, that is, a hole with a bottom. In this case, the upper and lower portions of the mounting plate portion can be completely blocked, and pests and dirt can be reliably prevented from passing from the back surface of the mounting plate portion of the pallet to the surface. Product health can be maintained over a long period of time.
In addition, when a complete blocking structure on the front and back is not required, a structure is provided in which an insertion hole without a bottom is provided, a recess is provided around the opening, and a insertion member is regulated using a positioning member having a collar. It can also be taken.

Next, in the first aspect of the invention, the main body portion of the upper frame member has a rib connecting the upper and lower wall portions therein, and the rib is directly below the packaging band disposition position. It is preferable to arrange | position so that it may be located in ( Claim 3 ). In this case, the presence of the rib can further increase the rigidity of the main body, and the tightening force can be further increased by the packaging band.

In addition, the main body portion has a concave portion that is recessed over the entire length on the upper surface, and the concave portion has a width wider than the width dimension of the packaging band and a depth of the concave portion of the packaging band. It is preferable that it is deeper than the thickness dimension ( Claim 4 ). In this case, the positioning of the packaging band disposed on the upper surface of the main body can be facilitated, and when the packed products are stacked, the product is placed on the pallet of the product placed above. It is possible to prevent the band from being damaged.

Further, the upper frame member, a plurality parallel aligned, it is preferably joined via a connecting member between them is made of an aluminum alloy (Claim 5). In this case, a plurality of upper frame members can be operated in an integrated state, and packing work can be rationalized. Also. The interval between the plurality of upper frame members can be made constant at all times, and the packaging accuracy can be improved.

Next, the sheet or the coil is preferably made of an aluminum alloy plate ( Claim 2 ). Aluminum alloy sheet materials are very fragile, and stabilization of the packaging state is very important. Therefore, the above-described packing structure is very effective .

And the said band guide part 4 is comprised by the insertion hole 40 provided in the inside of the leg part 3 over the full length. In this example, a square pipe is adopted as the band guide portion 4 and is constructed by being built in over the entire length of the leg portion 3.

Further, as shown in FIG. 6, a bending fulcrum portion 45 is provided on the upper side portion of the opening end portion of the insertion hole 40 on both side surfaces 33 of the leg portion 3.
As the bending fulcrum portion, one having an arcuate surface with a radius of curvature of 4 mm, that is, a round bar having a diameter of 8 mmφ was adopted.

Further, as shown in FIGS. 4 to 6, side cushioning materials 351 that absorb impact are disposed on both side surfaces 33 of the leg 3. In this example, a rubber plate having a thickness of 10 mm is employed, and the periphery of the opening of the insertion hole 40 of the band guide portion 4 is cut out.
Further, a bottom cushioning material 352 that absorbs an impact is disposed on the bottom surface of the leg portion 3. The bottom cushioning material 352 was made of plastic, and its thickness was 40 mm.

Next, as shown in FIG. 7, the upper frame member 6 used in this example is a product 9 made of a sheet or a vertical axis coil placed on a pallet, and a packaging band (iron band) 8 (FIG. 12). It is an upper frame member arranged on the upper surface of the product 9 when used for packaging and fixing.
The upper frame member 6 includes a long body portion 60 made of a hollow extruded shape made of an aluminum alloy, and a side wall member 61 made of an aluminum alloy plate welded so as to close both ends in the longitudinal direction of the body portion 60. It becomes more.

Moreover, the main-body part 60 has the recessed part 65 wider than the width dimension of the packaging band 8 and deeper than the thickness dimension which became depressed over the full length on the upper surface.
Moreover, in this example, as shown in FIG. 7, the thing of the structure which arranged the two upper frame members 6 in parallel and weld-joined them via the joining member 66 which consists of aluminum alloys was employ | adopted. These intervals were set so that the intervals between the concave portions 65 coincided with the intervals between the band guide portions 4 provided on the leg portions 3 of the pallet 1 described above.

Next, a packing structure in which products (coils made of aluminum alloy plates on the vertical axis) 9 are packed using the pallet 1 and the upper frame member 6 will be described.
As shown in FIG. 9, first, the product 9 is placed on the placement surface 20 of the pallet 1. Normally, the coil is manufactured in a horizontal axis state, but in order to achieve the above state, for example, a 90 ° reversing device called a down-ender is used.

Next, a packaging material (not shown) such as vinyl is used to cover the mounting plate portion 2 of the pallet 1 and the product 9, and then, as shown in FIG. 10, a circular protection adapted to the shape of the upper end surface of the product. The plate member 89 is covered.
Next, as shown in FIG. 11, the above-described upper frame member 6 is placed on the product 9, that is, on the protection plate member 89. At this time, it arrange | positions so that the leg part 3 of the pallet 1 and the upper frame member 6 may be aligned seeing in a perpendicular direction.

Next, as shown in FIG. 12, the packaging band 8 is inserted into the insertion hole 40 of the band guide portion 4 in the leg portion 3 of the pallet 1. Then, the packaging band 8 is passed over the recess 65 of the upper frame member 6 and fastened using a sealing material (not shown).
The packaging structure of this example has a structure obtained by the above procedure.

Next, the effect in this example is demonstrated.
First, in the pallet 1 of this example, a band guide portion 4 having an insertion hole 40 through which the packaging band 8 is inserted is provided in the leg portion 3 in parallel with the leg portion 3. Therefore, by passing the packaging band 8 through the insertion hole 40 of the band guide portion 4, the fastening position of the packaging band 8 can be easily determined, and the fastening operation can be greatly facilitated. Even if the fastened packaging band 8 is displaced, the movement of the packaging band 8 is prevented by the band guide portion 4, so there is no fear that the packaging band 8 will be displaced.

Furthermore, since the band guide part 4 of the pallet 1 of this example is provided in the full length along the back surface of the mounting board part 2, the insertion operation of the packaging band 8 is very easy.
Further, the bending fulcrum portion 45 is disposed at the opening end portion of the insertion hole 40 in the band guide portion 4. Thereby, the curvature radius which bends the packaging band 8 can be increased, damage to the packaging band 8 is reduced, and the packaging band becomes slippery when retightening or the like. Therefore, a stronger and more stable packing state can be obtained.

Further, side cushioning materials 351 that absorb impact are disposed on the side surfaces of both ends of the leg portion 3. Thereby, when mounting the some pallet 1 side by side, the malfunction which the metal leg parts 3 collide and deform | transforms can be prevented. In addition, since the packaging band 8 is disposed on the surface of the side cushioning material 351, the packaging band 8 can be prevented from being damaged.

Moreover, as the skin part 21, what combined the characteristic of durability and light weight called an aluminum alloy plate is employ | adopted, and since it is comprised in combination with the bone part 22, both strength and weight reduction are carried out. Can be satisfied.

  Further, as described above, the upper frame member 6 of this example is mainly configured by the long main body portion 60 made of a hollow extruded shape member made of an aluminum alloy. Therefore, it is very lightweight and can facilitate the packing work. Further, side wall members 61 made of an aluminum alloy plate are welded to both ends of the main body 60. Therefore, even if the packaging band 8 is strongly tightened through its upper surface, the hollow portion of the main body 60 can be prevented from being deformed due to the presence of the side wall member 61. In particular, in this example, the rib 62 that connects the upper and lower wall portions to the inside of the main body portion 60 is disposed so as to be located directly below the packaging band disposition position, so that the rigidity of the main body portion 60 is further increased. Can do.

  The main body 60 has the concave portion 65. Thereby, positioning of the packaging band 8 arranged on the upper surface of the main body 60 can be facilitated, and when the packed products are stacked, the product is placed on the pallet 1 placed on the upper side for packaging. It is possible to prevent the band 8 from being damaged.

  Moreover, two upper frame members 6 of this example are arranged in parallel, and the two are joined by welding via a connecting member 66 made of an aluminum alloy. The interval is matched with the interval between the leg portions 3 of the pallet 1. Therefore, the positioning of the upper frame member 6 is very easy, the interval between the upper frame members 6 can be always constant, and the packaging accuracy can be improved.

  Thus, in this example, since packing is performed by combining the excellent metal pallet 1 and the upper frame member 6, it is possible to suppress the load deviation and to stabilize the packing state. Therefore, it is possible to obtain an optimal packing structure for packing the product 9 made of an aluminum alloy that is very easily damaged.

(Example 2)
In this example, as shown in FIG. 13, a leg 302 having a different structure is employed instead of the leg 3 in the pallet 1 of the first embodiment.
That is, the leg portion 302 in this example is made of a steel material in which a bottom plate portion 321, a vertical plate portion 322, and a top plate portion 323 are arranged in a U-shape, and is formed of a rectangular pipe on the back surface of the top plate portion 323. A band guide part 5 was disposed.

The band guide portion 5 has an insertion hole 50, and the length thereof is not the entire length of the leg portion 302 but a length of a part along the leg portion 302. A bending fulcrum 55 made of a round bar is provided on the extension of the opening of the insertion hole 50.
Other structures are the same as those in the first embodiment.
In this case, the operation of inserting the packaging band 8 into the insertion hole 50 is slightly more difficult than in the case of the first embodiment, but other than that, substantially the same operational effects as those of the first embodiment are obtained.

(Example 3)
As shown in FIGS. 14 and 15 (a), this example employs a mounting plate portion 25 having a structure different from that of the first embodiment. Further, the mounting plate portion 25 is used for positioning the inner diameter of the coil. This is an example in which four bottomed insertion holes 27 for erecting the positioning member are provided at the center.
That is, as shown in FIG. 14 and FIG. 15, the mounting plate portion 25 has a plurality of two kinds of steel members 251, 252 and the like having different widths subjected to bending processing having a substantially U-shaped cross section, and welding the contact portions. And configured. And by this welding, the mounting surface 250 which mounts a product is formed in the flat form in which the whole surface was connected substantially.

  In addition, an insertion hole 27 is provided in the central portion of the mounting plate portion 25. Specifically, as shown in FIG. 15, a round pipe 271 having a bottom portion 272 is inserted from a hole provided in the placement surface 250 of the placement plate portion 25, and the upper end portion thereof is joined. By inserting a positioning member (not shown) into the insertion hole 27, it is possible to prevent the deviation of the inner diameter position 99 of the product 9 made of the vertical coil disposed on the mounting surface 250. It is. Moreover, since the bottomed round pipe 271 having the bottom portion 272 is employed, the upper and lower sides of the mounting plate portion 25 can be completely blocked, and pests and dirt can be removed from the back surface of the mounting plate portion 25 of the pallet. It can be reliably prevented from passing to the surface, and the soundness of the product can be maintained over a long period of time.

Other structures are the same as those in the first embodiment.
In the case of this example, for example, when a plurality of coils having a small width are stacked, the deviation of the coils can be prevented, which is particularly effective.
In other respects, the same effects as those of the first embodiment can be obtained.
When a complete blocking structure on the front and back sides is not required, as shown in FIG. 15B, an insertion hole 28 without a bottom is provided, a recess 281 is provided around the opening, and a positioning having a collar 291 is provided. A structure in which the insertion depth is regulated using the member 29 can also be adopted.

Next, a packing structure in which a product 95 made of a laminated product of sheets is packed using the pallet 7, the corner angle 77, and the upper frame member 78 will be described.
As shown in FIG. 20, first, the product 95 is placed on the placement plate portion 71 of the pallet 7. As shown in the figure, the product 95 is a thin rectangular sheet product, but has a rectangular parallelepiped shape by being laminated. Then, after the protective plate member 87 is put on the product 95, the above-described upper frame member 78 is placed.

  Next, as shown in FIG. 21, the corner angle 77 is brought into contact with the four side corners of the product 95. As described above, the corner angle 77 is composed of the two side plate portions 771 and 772 arranged at right angles so as to have an L-shaped cross section, and the upper plate portion 773 arranged at the upper end. Therefore, the two side plate portions 771 and 772 of the corner angle 77 are brought into contact with the two side surfaces sandwiching the side corner portion of the product 95, and the upper plate portion 773 is brought into contact with the upper surface of the product 95, whereby the corner angle 77 Are arranged in a state of being in close contact with the four side corners of the product 95. For this reason, it is not necessary to manually support the corner angle 77 until the corner angle 77 is fixed by hanging the packaging band 8.

Then, as shown in FIG. 22, in this state, the packaging band 8 is vertically arranged and tightened so as to pass over the side plate portions 771 and 772 of the corner angle 77. At this time, inserting the packaging band 8 through the insertion hole 740 of the band guide portion 74 of the pallet 7 is the same as in the other embodiments described above.
As shown in FIG. 23, it is also possible to fasten the packaging band 8 in the lateral direction so as to cross all the corner angles 77.

  In this example, as described above, packing is performed using the corner angle 77 having a special shape. Since this corner angle 77 has not only the two side plate portions 771 and 772 but also the upper plate portion 773, as described above, it can be arranged very easily at the side corner portion of the product. . In this state, the packaging band 8 is disposed vertically or horizontally so as to pass over the corner angle 77 and tightened, whereby the product 95 can be packaged and fixed without damaging it. Moreover, if this corner angle 77 is used, it can prevent that the laminated | stacked sheet | seat product slip | deviates, and can obtain the more stable packing state.

  Further, the upper and lower ends of the side plate portions 771 and 772 of the corner angle 77 are finished in an arc shape as described above. Therefore, the end portion exhibits a function as a bending fulcrum portion of the packaging band 8 and can be bent without damaging the packaging band 8.

  The effect of providing the band guide portion 74 on the pallet 7 is the same as that of the first embodiment.
