Description

[Detailed description of the invention] [Technical field of the invention] The present invention relates to a packaging bag for integrally packing a plurality of tires arranged continuously in the axial direction.
In particular, the present invention relates to a tire packaging bag that is easy to pack and has no risk of collapse.

[Prior art]

Generally, when exporting automobile tires, certain countries require five to seven tires to be arranged in succession in the axial direction and packed as one unit.

Conventionally, 5 to 7 tires are piled up in the axial direction and banded at three locations in the circumferential direction using ropes or tapes made of polypropylene or the like. Due to various circumstances, this banding is not performed when tires are shipped, and it is customary to bandage tires that have been shipped in bulk in a ship's hold.

However, this type of conventional packing method requires a great deal of time and effort, and there is a risk that the tightened portion of the tire may be permanently deformed. Furthermore, even if sufficient binding force is obtained at the beginning of binding, if a load is applied in the axial direction and each tire undergoes elastic deformation, the rope or tape will loosen, and in this state, an external force will be applied in the radial direction. In such cases, the axes of each tire may be misaligned, resulting in the load collapsing, and there is a problem in that it is not easy to return to the original packaging shape.

[Purpose of invention]

The present invention was developed in view of the current situation, and it is easy to pack and can significantly shorten the working time.Furthermore, there is no risk of the load collapsing even when external force is applied in the axial and radial directions, and it is easy to package. To provide a packaging bag for packing tires that can sufficiently protect the surface of tires.

[Summary of the idea]

The present invention includes a cylindrical bag body having a bottom at one end and a tire loading/unloading section at the other end;
A tightening rope that also serves as a hanging rope is arranged along the periphery of the loading/unloading section of the bag body and tightens the loading/unloading section of the bag body in which tires are stored, The length of the bag is 1 to 5% longer than the diameter of the tire, and an opening approximately the same size as the inner diameter of the tire is provided at the center of the bottom of the bag body. A space approximately the same size as the inner diameter of the tire is left in the inner diameter of the tire so that it can be tightened with a tightening rope, and when the tire is packaged, a penetration section is formed from the loading/unloading section to the bottom, making it easy to pack and transport. It is characterized in that it is easy to load, there is no risk of the load collapsing, and the surface of the tire can be protected.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show an example of a tire packaging bag according to the present invention, and this packaging bag 1 includes:
A laminate material of a flat yarn woven fabric made of polyolefin resin such as PE or PP and a polyolefin resin film placed on the outer surface of the woven fabric is sewn into the seam part 2.
The bag body 2 is provided with a bag body 2 formed in a cylindrical shape through a, and this bag body 2 has 5 to 7 tires T arranged continuously in the axial direction inside the bag body 2, as shown in FIG.
It has enough transparency that the display on the outside surface can be seen from the outside. In addition, the inner diameter R ₁ of this bag body 2 is
As shown in FIG. 3, the length is set to be 1 to 5%, preferably about 1.5%, relative to the diameter _R2 of the tire T, and as a result, as will be described later, the length is It is easy to store the items, and even if an external force is applied after the items are packed, the items will not collapse.

A bottom portion 3 is formed at the lower end of the bag body 2 in FIG. 1 to prevent the tire T stored in the bag body 2 from slipping out.

As shown in FIGS. 1 and 2, this bottom portion 3 is constructed by sewing the lower end of the bag body 2 inward in the circumferential direction in a triangular shape at six points, for example, to form a sewn-in portion 3a. At its center,
A polygonal opening 3b is formed having each of the sewn-in portions 3a as its apex. The size of the opening 3b is set so that its average inner diameter is approximately the same as the inner diameter _R3 of the tire T shown in FIG.

On the other hand, at the end of the bag body 2 on the side opposite to the bottom part 3,
As shown in FIGS. 1 and 2, a tire T loading/unloading section 5 is formed which is opened and closed by a tightening rope 4.

As shown in FIGS. 1 and 2, this insertion/removal section 5 is formed by folding and sewing the upper edge of the bag body 2 inward or outward to form a cylindrical rope insertion section 5a. Two notches 6a and 6b are provided at the upper end edge of 5a at equal intervals in the circumferential direction, and a rope 4 made of, for example, polypropylene is inserted through the rope insertion portion 5a and is pulled out from one of the notches 6a. When the tire T is stored in the bag body 2, the loading/unloading section 5 is designed to be opened to the same diameter as the bag body 2, as shown in FIG. After storing the tire T in the bag body 2, the first
As shown in the figure, the diameter of the rope 4 is reduced by wrapping the tip of the rope 4 pulled out from the notch 6a around the portion of the rope 4 located in the notch 6b and tightening it, thereby integrally connecting each tire T in the bag body 2. It is becoming more and more united.

In the diameter-reduced state shown in FIG.
Similarly to the opening 3b, the diameter is set to be approximately the same as the inner diameter _R3 of the tire T shown in FIG. This space 7 and the opening 3b allow the tire T
In the packing state, the tire T is attached to the axial center of the packaging bag 1.
A penetrating portion passing through the axis is formed. In addition, when the diameter of the loading/unloading section 5 is reduced, the rope 4 is arranged in the radial direction passing through the center of the space 7 as shown in FIG. It has come to serve as both.

Next, the effect will be explained.

When packing the tire T, first, as shown in FIG. 2, and are sequentially stored in the axial direction as shown in FIG. And a predetermined number of tires T
is stored in the bag body 2, the tip of the rope 4 pulled out from the notch 6a is wrapped around the part of the rope 4 located at the notch 6b and drawn, and the rope 4 is fastened in this state. . As a result, the diameter of the loading/unloading section 5 is reduced as shown in FIG. 1, and each tire T is integrally bound by the packaging bag 1.

By the way, when each tire T is inserted into the bag body 2 from the loading/unloading section 5, it is customary to insert the tire T in a state in which the axis of the tire T is orthogonal to the axis of the bag body 2, as shown in FIG.

In this case, the inner diameter R ₁ of the bag body 2 is set to be 1 to 5% longer than the diameter R ₂ of the tire T, so for example, if the diameter R ₂ of the tire T is 660 mm, the width W
(see Fig. 3) is 160 mm, the circumference of the tire T in the state shown in Fig. 4 is 1640 mm, whereas the circumference of the bag body 2 is 2093 to 2176 mm, which is 453 to 453 mm.
The length is 536mm. Therefore, a large gap is formed between the inner circumferential surface of the bag body 2 and the outer circumferential surface of the tire T, and the tire T can be inserted into the bag body 2 very easily.

On the other hand, when the tire T is stored in the bag body 2, the distance between the outer circumferential surface of the tire T and the inner circumferential surface of the bag body 2 is 0.33 to 1.65 cm, and the diameter R ₂ of the tire T is
Since the value is extremely small for each tire T
can be bundled with their axes almost aligned.

Furthermore, unlike the case of conventional ropes or tapes, the inner diameter R ₁ of the bag body 2 does not change at all even if an external force is applied to the packaging bag 1 in the axial direction after packing and the bag body 2 becomes somewhat slack. Therefore, tire T
The positional deviation in the radial direction is extremely small, and the positional deviation does not occur to the extent that cargo collapse occurs. Furthermore, even if the packaging bag 1 is slightly deviated from the position shown in FIG. 1, it can be easily returned to its normal state due to the impact if the packaging bag 1 is brought down so that the peripheral surface of the bag body 2 is in contact with the ground.

In addition, the bag body 2 is transparent enough to allow the display of the tire T circumferential surface to be seen from the outside, so even when packing multiple types of tires T at the same time, other types of tires T may be mixed in by mistake. There is little risk of this happening, and this can be easily detected.

Further, since the outer surface of the tire T housed in the packaging bag 1 is almost completely covered by the packaging bag 1, the surface of the tire T can be protected and a buffering effect against external force can also be obtained. These effects are noticeable for unwrapped tires T, but for wrapped tires T
It is also effective because it can simplify packaging.

Furthermore, unlike conventional banding with rope or tape, large tightening force is not applied to the tire T stored in the packaging bag 1, so the tire T may be permanently deformed. There is no fear at all.

Furthermore, in the axial center of the packaging bag 1, a penetration part passing through the axial center of the tire T is formed by the opening 3b and the space 7, so for example, a long pipe is attached to one claw of a forklift. However, if this pipe is inserted through the penetration part, it is convenient because a large number of packaging bags 1 can be easily transported by a forklift. It is also possible to attach a predetermined number of tires T to the pipe in advance, attach the packaging bag 1 to these tires T from the tip end of the pipe, and tie the tires T by tightening the rope 4 in that state. This not only simplifies the packing process but also allows the product to be transported as is.

In addition, since the rope 4 serves both as a tightening rope for the loading/unloading section 5 and as a hanging rope, the structure is simplified compared to when each rope is provided separately, and the rope 4
By lifting the packaging bag 1, the packaging bag 1 is pulled in the axial direction, and the positional deviation of the tire T can be corrected.

In addition, the packaging bag 1 has a certain shape and the tires T are housed therein, so it is necessary to maintain the bundled shape of each tire T by banding. In contrast, there is no need to apply strong force to the tire T to maintain the bundled shape. That is, in the case of the packaging bag 1, the bundled shape can be maintained simply by preventing the tire T from slipping out from the loading/unloading section 5. Therefore, basically, the tires T can be bundled without applying any force at all, and there is no deterioration of the tires T due to the binding. Since the bag body 2 is made of a laminate material of a polyolefin resin flat yarn woven fabric and a film, elongation and deformation of the material have no practical effect, and therefore the packaging bag 1 in which the tire T is stored. The above effect can be obtained even after lifting with strong force.

The present inventors conducted an experiment on the dimensional relationship between the inner diameter R ₁ of the bag body 2 and the diameter R ₂ of the tire T using the packaging bag 1 described above. As a result, in the case of R ₁ <1.01R ₂ , although the bundling condition is safe, it is not easy to insert the tire T into the bag body 2, and in some cases, the tire T may not be in the state shown in FIG. 3, there is a risk that the tire T or the bag body 2 will be strained, and conversely, R ₁ >
In the case of 1.05R ₂ , it was confirmed that although it was easy to insert the tire T into the bag body 2, the positional deviation of the tire T became large and the binding state became unstable. By setting R ₁ ≈1.015R ₂ , it was found that the tire T could be easily inserted into the bag body 2, and the binding state could be stabilized. This result was commonly obtained for all tires T regardless of the size of _R2 .

In the above embodiment, the bottom part 3 is formed by providing six sewn-in parts 3a in the circumferential direction. Good too.

Furthermore, in the above embodiment, the bag body 2 is formed of a laminate material of a polyolefin resin flat yarn woven fabric and a polyolefin resin film, but the bag body 2 is not limited to this, and may be made of other synthetic resin sheets, or may be made of other than synthetic resin. Materials may also be used. Regarding the transparency of the bag body 2, the bag body 2 may be opaque if only a single type of tire T is handled or if the bag body 2 is provided with a confirmation window.

Although not specifically explained in the above embodiments, if the strength of the seam 2a of the bag body 2 or the rope insertion part 5a of the loading/unloading section 5 is insufficient, a reinforcing material may be provided or the end portion may be folded multiple times. It may be reinforced by a method such as suturing at multiple locations.

[Effect of idea]

As explained above, the present invention consists of a cylindrical bag body having a bottom at one end and a tire loading/unloading section at the other end, and a bag arranged along the periphery of the loading/unloading section of the bag body to store tires. The inner diameter of the bag body is set to be 1 to 5% longer than the diameter of the tire placed inside the bag body, so unnecessary force is applied to the tire. It can be easily packed in one piece without applying any stress, and there is no risk of the cargo collapsing even if external force is applied after packing. Moreover, the bag body can protect the surface of the tire and also provide a buffering effect against external forces.

In addition, an opening approximately the same size as the inner diameter of the tire is provided at the center of the bottom of the bag body, and a space approximately the same size as the inner diameter of the tire is provided at the center of the bag body. The bag can be tightened with a tightening rope, and a penetration section from the loading/unloading section to the bottom is formed in the tire packaging bag state.For example, a long pipe can be attached to one claw of a forklift and this pipe By inserting the bag through the penetrating portion, a large number of packaging bags can be easily transported.

In addition, if a predetermined number of tires are attached to the pipe in advance, a packaging bag is attached to these tires from the tip of the pipe, and the tightening rope is tied on the pipe as it is. This makes it easier to transport the packaging bag as it is.

In addition, since the tightening rope also serves as a hanging rope, the structure is simplified and costs can be reduced compared to when each of these is provided separately.
In addition, by lifting the packaging bag using the tightening rope as a hanging rope, the packaging bag is pulled in the axial direction, so that misalignment of the tire can be automatically corrected.
