Is what you are doing.

The above-mentioned roll package in which the roll is wrapped by using the end wall and the lower beam is provided with a loading means such as a claw of a forklift, which is capable of lifting and lowering the cargo handling vehicle, below the lower beam. It can be inserted directly into the space and transported directly. In other words, according to the roll packaging end wall of the present invention, a pallet is used as in the prior art, even if the roll has a large weight or a roll that does not meet the pallet standards. It can be packed so that it can be directly transported by a forklift or the like.

In the wound packaging end wall according to the present invention, the height of the leg is preferably 50 mm or more.

If the height of the legs is 5 O mm or more, the claw of a forklift, which is most commonly used as a cargo handling vehicle equipped with a loading means capable of lifting and lowering, can be inserted below the two lower beams. It becomes possible.

In the wound packaging end wall according to the present invention, the main body is substantially square, and the support means is arranged such that a center axis of the core supported by the means substantially coincides with a center of the main body. It is preferable that it is formed in a suitable position.

According to the above configuration, since the core is supported at the center of the square main body, the area of the end wall with respect to the winding diameter of the roll to be conveyed can be suppressed, and the transport efficiency can be increased.

In the wound packaging end wall according to the present invention, the main body part and the leg part are formed May be shaped.

If the end wall is integrally formed of plastic as described above, the number of parts is reduced and the cost is reduced accordingly.

On the other hand, in the wound end wall for rolls according to the present invention, a case is formed in which a main body member constituting the main body portion and one or more leg members constituting the leg portion are joined to each other. There is also.

In the above case, the main member and the leg member are joined and integrated to be used for direct conveyance of the wound package by a forklift or the like. It is possible to appropriately use the form used for transporting the product package in units of pallets.

As a first support mode of the end wall for winding a roll according to the present invention, the wound material is wound around a middle portion of the length of the core, and the support means extends the end of the core from above. It may be formed of a groove formed downward from the upper end of the main body so that it can be inserted and having a stop surface for mounting the end of the core.

In the case of the first supporting mode, the wound material is first lifted, and the two end walls are held in an upright state by the lower beam, and then the wound material is lowered. Since the end of the core of the product is placed and supported on the stop surface of the groove in the end wall, it is possible to easily assemble the wound package even when the weight of the wound product is large. it can.

In the first support mode, it is preferable that the elastic body covering at least the stop surface in the groove is exchangeably mounted.

If the elastic body as described above is exchangeably attached to the end wall, sufficient holding is possible even if the outer diameter of the core of the wound material to be packaged is slightly changed. The elastic body can be attached to the end wall in a replaceable manner, for example, by having a complementary shape capable of fitting the side surface of the groove and the elastic body.

In the above case, it is more preferable that the stop surface has irregularities. This is because the amount of deformation of the elastic body in the circumferential direction of the core is increased or decreased due to the unevenness of the stop surface, whereby the holding force when the outer shape of the core changes can be improved.

In the first supporting mode, the core may be moved in a length direction of the core to an outer portion of the groove. It is preferable that the wall for preventing movement is formed so as to reduce the width of the groove. According to the above configuration, the elastic material prevents the core from slipping, and prevents the end of the core from jumping out of the groove in the end wall by the above-described wall that narrows the width of the groove. It can be prevented from being damaged or deformed due to collision.

In the first support mode, holes may be formed at lower ends on both sides of the inner surface of the main body to fit ends of the two lower beams.

In the case of the above configuration, the assembly is simple because only the end of the lower beam needs to be fitted into the hole in the end wall.

In the above case, it is preferable that a protrusion for receiving an end of the lower beam is formed on an inner surface of the main body.

(First embodiment)

A wound package according to a first embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view showing the configuration of a wound package according to the first embodiment. In FIG. 1, a roll package 1 includes a roll 2, two plastic end walls 3 arranged at both ends of the roll 2, and a lower portion of the two end walls 3. It is provided with two hollow lower beams 4 made of steel, which are passed between them, and two upper beams 5 which are passed over the upper ends 3 a of the two end walls 3.

The roll package 1 is bound with a polypropylene band (hereinafter referred to as a PP band) 6 for the purpose of reinforcing the package. The method of tying the rolled package 1 with the PP band 6 is changed according to differences in conditions such as the type and weight of the roll to be transported.

The roll 2 has a thickness of 10 mrr with an inner diameter of 6 inches! An example in which a plastic film 2b for a magnetic tape is wound in a roll shape around an intermediate length of a paper core 2a of up to 20 mm. The weight of such a roll 2 is mainly from 100 kg to 600 kg.

A steel pipe is suitable for the lower beam 4 in order to transport such a very heavy roll 2 by forklift.

FIG. 2 is a perspective view showing a configuration of a roll packaging end wall 3 which is a component of the roll packaging 1.

The end wall 3 is made of plastic and has a height 90 mm longer than the width. Here, the height of the end wall 3 is the length between the upper end 3a and the lower end 3b. For example, a width of 700 mm and a height of 790 mm, or a width of 550 mm and a height of 6 For example, 40 mm. The thickness of the end wall is generally about 30 to 60 mm. In other words, the end wall 3 has a square main part 31 and two legs 32 extending downward from the lower ends of both sides of the main part 31, and the legs have a height of 9 O mm. Have. The main body 31 has, for example, a side length of 700 mm or 550 mm.

A groove (supporting means) 3c is formed downward from the upper end 3a of the end wall 3. A stop surface on which the end of the core 2a is placed is formed at the bottom of the groove 3c. An elastic body 7 having both ends bent in an L-shape is attached to the stop surface of the groove 3c. The width of the groove 3c is opposite to the side on which the windings 2 are arranged, that is, the outside is narrowed by the wall 3d. A slit 3e into which both ends of the elastic body 7 are fitted is formed in the stop surface of the groove 3c. Here, the fitting portion is formed by the slit 3e, but may be another shape such as a circular concave portion. Further, the place where the elastic body 7 is formed is not limited to the end of the elastic body 7 but may be a central part or other places. It is preferable that it is provided at the end so that it cannot be removed.

Also, when the end of the core 2a of the wound material 2 is placed on the stop surface of the groove 3c, the groove 3c is positioned so that the core 2a is substantially at the center of the square having the upper end 3a as one side. Are formed. That is, when viewed from the side of the roll 2, the end wall 3 has a shape in which the lower portion of the square having the upper end 3a as one side extends 90 mm to the lower end 3b. Examples of the elastic body 7 include an elastomer such as hard rubber and a foamed plastic.

The hole 3 f is formed so that the bottom surface of the lower beam 4 is located at a height of 90 mm from the lower end 3 b of the end wall 3 when the lower beam 4 is attached. That is, a hole 3 f into which the end of the lower beam 4 is fitted is formed at the lower end of both ends of the square main body 31. The distance between the hole 3 f and the side surface of the end wall 3 is set so as to have a strength that does not cause cracking due to the twist of the lower beam 4. A projection 3 g is formed on the inner surface of the end wall 3 so as to extend the bottom surface of the hole 3 f. The end of the lower beam 4 can be placed on the projection 3a and the lower beam 4 can be slid into the hole 3f.

If the bottom surface of the lower beam 4 is at a level of 50 mm or more from the lower end 3 b of the end wall 3, the forklift claw enters below the lower beam 4, but considering the use of a hand lift, etc. mm or more is preferable, and considering the unevenness of the floor, 90 m It is preferably at least m.

Notches 3 for fitting the upper beam 5 are formed on both sides of the upper end 3 a of the end wall 3. On the bottom surface of the notch 3h, a convex portion 3i that fits into a concave portion 5a formed at the end of the lower surface of the upper beam 5 is formed. By fitting the upper beam 5 into the notch 3 h, the end wall 3 can be prevented from tilting back and forth.

FIG. 3 is a view showing another embodiment of the notch 3h shown in FIG. The notch 3 ha shown in FIG. 3 is closed by a wall on the side opposite to the side on which the roll 2 is arranged. In this case, it is possible to prevent the end wall 3 from falling down to the side of the roll 2 without providing the projection 3 i.

The end wall 3 is provided with a lock mechanism 3k on the surface on the side where the wound material 2 is arranged, that is, on the inner surface, which includes a base having a triangular planar shape and a columnar projection protruding from the base. The cylindrical protrusions of the lock mechanism 3 k are fitted into circular recesses 3 n formed on the outer surface of the other end wall 3 when only the end wall 3 is transported in an overlapping manner, so that a plurality of overlapping end walls are formed. 3 can be prevented from shifting. The triangular base of the lock mechanism 3k serves as a spacer when a plurality of end walls 3 are stacked.

In addition, recesses 3 m are formed in the upper and lower portions of both side surfaces of the end wall 3 to prevent the PP band 6 from coming off when connecting the PP band 6. The lower recess 3 m is formed at a position higher than the lower surface of the lower beam 4 so that the insertion of the forklift claw is not obstructed by the PP band 6.

The stop surface of the groove 3c shown in FIG. 2 or 3 has a smooth U-shaped cross section. In this case, a relatively uniform force is applied to the core 2 a of the wound material 2 from the elastic body 7. On the other hand, irregularities are formed on the stop surface of the groove 3ca shown in FIG. By making the stop surface uneven as shown in FIG. 4, the amount of deformation of the elastic body 7 on the unevenness increases, and the grip force also improves. Therefore, it becomes easy to cope with variations in the core diameter depending on the thickness of the core 2a. Note that the slit 3ea functions in the same manner as the slit 3e shown in FIG.

Next, the assembly of the wound package will be described with reference to FIG.

As shown in FIG. 5, first, the two end walls 3 are connected by the lower beam 4, and the two end walls 3 are made independent. Furthermore, by attaching the auxiliary tool 20 to the side of the end wall 3, Make sure that it stands upright. Next, the metal rod 8 is inserted into the core 2 a of the roll 2, and the roll 2 is lifted by hanging the belt 9 on both ends of the metal rod 8. Then, the roll 2 is lowered, the end of the core 2 a is placed in the groove 3 c of the end wall 3, and the roll 2 is supported by the two end walls 3. Next, the end of the upper beam 5 is fitted into the notch 3 h of the end wall 3. Finally, loosen the belt 9 and pull out the metal rod 8. After that, a treatment such as tying the wound package 1 with the PP band 6 or covering the wound package 1 with a plastic bag is performed.

In the first embodiment, the surface of the end wall 3 on the side opposite to the side on which the wound material 2 is arranged is, for example, as disclosed in Japanese Patent No. 2639512. Alternatively, a number of recesses may be formed to form ribs to reduce the amount of plastic used.

(Second embodiment)

Next, a wound package according to a second embodiment of the present invention will be described with reference to FIGS.

FIG. 6 is an assembly diagram showing the configuration of a roll package according to the second embodiment. In FIG. 6, the roll package 11 is composed of a roll 12, two plastic end walls 13 disposed at both ends of the roll 12, and two end walls. It consists of two hollow lower beams 14 of steel passed between 13 and two upper beams 15 bridged over the upper ends of two end walls 13. I have. The belt 19 is used only for assembling the roll package 11 and is not a component of the roll package 11.

An example of the wound material 2 is one in which a plastic film for magnetic tape 12b is wound in a roll around a paper core 12a having a 3 inch inner diameter and a thickness of several mm to 20mm. As The weight of such a roll 12 is mainly from 100 kg to 400 kg.

FIG. 7 is a perspective view showing the configuration of a roll transporting end wall 13 which is a component of the roll package 11.

The end wall 13 is made of plastic and has a height 90 mm longer than the width. Here, the height of the end wall 13 is the length between the upper end 13a and the lower end 13b. is there. For example, a width of 700 mm and a height of 790 mm, or a width of 550 mm and a height of 640 mm. The thickness of the end wall 13 is generally 30 mm to 60 mm. That is, the end wall 13 has a square main body 131, and two legs 1332 extending downward from the lower ends of both sides of the main body 131, and the legs are 90 mm in length. It has a height. The main body 131, for example, has a side length of 700 mm or 550 mm.

Notches 13 ha for fitting the upper beam 15 are formed on both sides of the upper end 13 a of the end wall 13. The notch 13 ha is closed by a wall on the side opposite to where the scroll 12 is placed. In this case, since the end face of the upper beam 15 hits the wall of the notch 13 ha, it is possible to prevent the end wall 13 from falling down to the roll 12.

Note that, in place of the notch 13 ha, a combination of the same shape as the notch 3a and the upper beam 5 as shown in FIG. 2 may be used.

The end wall 13 is provided with a lock mechanism 13k on the surface on the side where the wound material 12 is arranged, that is, on the inner surface, the lock mechanism comprising a base having a triangular planar shape and a columnar projection protruding from the base. ing. The cylindrical projection of the lock mechanism 13k is fitted into a circular recess 13u formed on the outer surface of the other end wall 13 when only the end wall 13 is transported. Therefore, it is possible to prevent the overlapping end walls 13 from shifting. The triangular base of the lock mechanism 13k serves as a spacer when a plurality of end walls 13 are stacked.

In addition, depressions 13 m are formed in the upper and lower portions of both side surfaces of the end wall 13 to prevent the PP band from coming off when connecting the PP band. The lower dent 13 m is formed at a position higher than the lower surface of the lower beam 14 so that the insertion of the forklift claw is not obstructed by the PP band.

A cylindrical support projection 13p is formed at a substantially central portion of a square having the upper end 13a of the end wall 13 as one side. That is, when viewed from the side of the wound material 12, the end wall 13 has a shape in which the lower part of the square having the upper end 13a as one side is extended by 9 O mm to the lower end 13b.

The support projection 13 p is cylindrical and has a plurality of portions that protrude in an arc on the outer periphery. Has a petal-shaped cross section. More specifically, as shown in FIG. 8, the protruding portion 13 p has a perfect circular inner circumference, while the outer circumference is depressed by 45 ° with respect to the vertical and horizontal directions. As a result, the wall thickness in the circumferential direction changes at a cycle of 90 °. Since a part of the outer periphery of the supporting projection 13 p projects in the vertical direction and the horizontal direction as described above, it becomes easy to insert the supporting projection 13 p into the end of the core 12 a. However, since the outer periphery of the protrusion 13 p is gentle, the use of a paper tube or the like as a core can suppress the generation of powdery foreign matter caused by damage to the inner surface of the core. The cross section of the supporting projection is not particularly limited as long as the projecting portion of the outer periphery is a gentle arc-shaped petal. In general, the number of petals is 3 to about L0, preferably 4 It is made up to about 8 petals. In addition, as shown in Fig. 8, the supporting projections are formed by continuously projecting the outer periphery in the circumferential direction, and intermittently by placing an arc portion with a constant distance from the center between them.
