Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaged lead acid battery.
[0002]
[Prior art]
Lead-acid batteries, particularly lead-acid batteries for automobiles, exist in a state where external terminals and liquid plugs protrude from the upper surface (battery cover surface). This is due to the fact that the external shape is defined by the JIS standard like external terminals. Therefore, it may be impossible to design the lead-acid battery to have a substantially rectangular parallelepiped appearance.
When a large number of lead storage batteries are loaded, it is ideal that the appearance is the rectangular parallelepiped shape. In view of this, a lead storage battery has been inserted and packed in a box mainly made of paper typified by corrugated cardboard so that the appearance of the rectangular parallelepiped has been realized.
[0003]
[Problems to be solved by the invention]
However, the conventional means for inserting and packing a lead storage battery in a cardboard box has the following drawbacks.
(1) Since the packaging material is cardboard, that is, paper is the main material, the compressive strength is weak. This may cause the packing material to be compressed and deformed in the vertical direction when a large number of packed lead storage batteries are loaded and transported, and the rectangular parallelepiped shape cannot be maintained. If the rectangular parallelepiped shape cannot be maintained, some of the stacked lead storage batteries may be inclined and fall. Since the main material of the packaging material is paper, the compression deformation is particularly likely to occur when exposed to an environment that easily absorbs moisture.
(2) When the lead storage battery is actually used, no packaging material is required. Therefore, a large amount of cardboard becomes an unnecessary object, that is, garbage. The reason for describing “a large amount” here is that the amount of corrugated cardboard as a packing material having a strength that can be transported by inserting a lead storage battery having a large weight per unit volume inevitably increases. It is. Further, the reason for becoming “garbage” is that it is difficult to reuse the box-shaped cardboard in its original form and maintaining the strength when it is no longer needed. These can be said to be so-called excessive packaging, and cause a large environmental load, which is not a preferable situation.
(3) Pay attention to the workability of packing lead-acid batteries. First, there is a process of assembling the cardboard into a box shape, and then, as described above, there is a process of inserting a lead storage battery having a large weight per unit volume into the cardboard box, and if necessary, a cushioning material is placed in the cardboard box. There is a process of arranging. The cushioning material may be made of polystyrene foam or cardboard. It is very difficult to mechanize all of these processes, and workability is never good.
[0004]
The problem to be solved by the present invention is that in a packaged lead-acid battery, the function of packaging is exhibited without using a cardboard box , the environmental load due to disposal of the packaging material is reduced, and the packaging workability is further improved. It is to do.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, a plate-like cushioning material having a thickness not less than the maximum height of the protrusion is disposed on the surface having the protrusion of the lead-acid battery according to the present invention so as to avoid the protrusion, and the buffer The material is fixed to the outer surface of the battery by a bundling means, and has an accommodation space for accommodating the lead-acid battery related parts on the upper surface of the buffer material, and the buffer material covers the upper surface of the accommodation space. And the lead storage battery are tightly wrapped with a transparent film having stretchability, and the tight packaging wraps the lead storage battery and the cushioning material one or more times while fixing the end of the film and pulling it. It is a packaging means for operating and integrating the overlapping parts of the films . Specific examples of the protrusion are the external terminal 4 and a liquid stopper.
At this time, if the means for tight wrapping is a transparent film, the information on the lead storage battery 1 printed on the side of the lead storage battery 1 and the like can be confirmed from the outside, and the accommodation space in the cushioning material It is easy to confirm the contents of the lead-acid battery related parts housed in the container.
[0006]
By having the said structure, the packaged lead storage battery can be made into a substantially rectangular parallelepiped external appearance. In other words, an ideal shape can be obtained when the packaged lead storage battery is loaded.
Moreover, the deformation | transformation by compression when loading the packaged lead acid battery can be suppressed. The reason is that the stress (compression force) at the time of loading is applied to a battery case material (usually made of polyethylene or the like) that is much stronger than the box-like cardboard or the like that was a conventional packing material. . The stress at the time of loading is also applied to the cushioning material 2, but the material of the cushioning material 2 having a compressive strength that can suppress deformation due to compression can be appropriately selected according to the expected handling of the packaged lead storage battery. That's fine.
That is, the above-mentioned drawback (1) can be overcome by adopting the above configuration.
[0007]
Moreover, the usage amount of a packaging material can be reduced dramatically by having the said structure. The reason is that the member expressed as the packing material in the above configuration is only the cushioning material 2 and, in some cases, the stretchable film 3 is added.
Moreover, by having the said structure, the reuse of the shock absorbing material 2 which is a packaging material may also be attained. This is because the cushioning material 2 is plate-shaped. Since the plate-like member has a simple structure as compared with the box-like member, it is difficult to be deformed or deteriorated. Moreover, the material which is hard to deteriorate can be suitably selected according to how the packaged lead storage battery is expected to be handled. In this way, the environmental load can be reduced by adopting the above configuration. That is, the above-mentioned drawback (2) can be overcome.
[0008]
Moreover, by having the said structure, packing workability | operativity can be made favorable. The reason is that in order to realize the above-described configuration, the buffer material 2 is simply placed and fixed.
By adopting the above configuration in this way, the packing workability can be improved. That is, the above-mentioned drawback (3) can be overcome.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
An example of the embodiment of the present invention will be described below with reference to FIG.
The lead storage battery 1 has substantially only the external terminals 4 as protrusions from the upper surface (battery cover). The buffer material 2 is placed on the upper surface of the lead storage battery 1. At that time, the cushioning material 2 is made of foamed polystyrene having a thickness 5 mm thicker than the maximum height of the external terminal 4, and the width and length are substantially equal to the size of the upper surface of the lead storage battery 1. Then, as shown in FIG. 1, the buffer material 2 is notched so as to avoid the external terminal 4, and is aligned in the upper surface width and length direction of the lead storage battery 1 as shown in FIG. Then, the buffer material 2 and the lead storage battery 1 are tightly packed together with a transparent film 3 made of polyethylene, thereby fixing the buffer material 2 at the position where it is arranged.
The tight packaging means that the end of the stretchable film is fixed, the lead storage battery 1 and the cushioning material 2 are wrapped one or more times while pulling it, and the overlapping part of the film is integrated by means such as heat welding It is a packaging means.
These series of packing operations can be easily mechanized and automated.
[0010]
In this example, as a means for avoiding the external terminal 4 from which the cushioning material 2 is a protrusion, a notch is made in the external terminal 4 portion as shown in FIG. 1, but other means may be used. For example, a means for providing a recess in the cushioning material 2 and accommodating the external terminal 4 in the recess. The former means (means for notching) has an advantage that the operation of molding the cushioning material 2 becomes easy. The latter means is that the external terminal 4 can be further protected from the applied pressure in the vertical direction when a plurality of packed lead-acid batteries are stacked, etc., and the external terminal 4 is movable around the surrounding area by the vertical pressure. This is advantageous in that it can be prevented from being damaged. The same applies to the case where the protrusion is other than the external terminal 4.
Further, in this example, the thickness of the cushioning material 2 is 5 mm thicker than the maximum height of the external terminal 4 as a protrusion, but the effect of the present invention can be obtained as long as it is greater than the maximum height of the protrusion.
Further, in this example, the width and length of the cushioning material 2 are made substantially equal to the size of the upper surface of the lead storage battery 1, and are aligned and arranged in the width and length direction of the upper surface of the lead storage battery 1 as shown in FIG. The lead-acid battery thus made was a substantially rectangular parallelepiped having the “ideal shape” described above. However, as long as the effect of the present invention is obtained, the width, length, and arrangement of the cushioning material 2 may be appropriately changed.
In this example, polystyrene foam is used for the cushioning material 2, but the material can be suitably used for laminated cardboards, honeycomb-shaped paper moldings, and the like. Laminated cardboards and honeycomb-shaped paper moldings can be used, although they are the same paper materials as the box-shaped cardboards used conventionally. This is because the cushioning material 2 is plate-shaped. Since the plate-like member has a simple structure as compared with the box-like member, it is difficult to be deformed or deteriorated.
[0011]
In this example, the projecting object is only the external terminal 4, but other than that, when packing the projecting object of a degree that cannot be ignored in the packaging according to the present invention, for example, a lead storage battery 1 having a liquid plug, etc. The shape of 2 is made so as to avoid the protrusion.
For protrusions that are negligible in the packaging according to the present invention, such as ribs on the outer side surface of the battery case material or slight recesses on the surface of the battery lid, the shape of the cushioning material 2 is made to avoid the protrusions. do not have to.
The present invention is applicable even when the protrusion from the top surface, bottom surface, or side surface of the lead storage battery is an accessory, for example, a band handle. When the accessory is a protrusion that cannot be ignored in the packaging according to the present invention, the cushioning material 2 is shaped so as to avoid the protrusion. Moreover, when the said accessory is a protrusion of the grade which can be disregarded with the packaging which concerns on this invention, it is not necessary to make the shape of the shock absorbing material 2 into a shape which avoids this protrusion.
When the accessory is a band-like handle, the above-described tight packaging can be performed after the band-like handle is brought into contact with the upper surface of the buffer material 2 or the side surface of the lead storage battery in FIG.
[0012]
In this example, tight packaging is selected as means for binding and fixing the cushioning material 2, but other means may be used. For example, there are means for fixing by tying with a string, means for fixing by covering the film with a heat-shrinkable film and then heating and shrinking the heat-shrinkable film. The means using the former string has an advantage that the string can be easily reused.
Moreover, although the transparent film was used for the stretchable film used for tight packaging, it may be opaque. However, it is preferable to be transparent because the contents can be easily confirmed. Moreover, the material of the film should just have a drawability, and a polypropylene, the blend material of a polypropylene and polyethylene, etc. can use it conveniently.
Moreover, when tight-packaging, it is not necessary to wrap so that the whole surface of the lead storage battery 1 and the buffer material 2 may be wrapped, and the lead storage battery 1 and / or the buffer material 2 may be partially exposed. However, it is preferable to wrap the lead storage battery 1 and the cushioning material 2 so as to wrap the entire surface because dust and the like can be prevented from adhering to the lead storage battery.
[0013]
Depending on the type and application of the lead-acid battery, there may be a projecting object such as an external terminal on the side or bottom surface. In that case, the cushioning material 2 may be arranged in accordance with the present invention on the surface where the protrusions are present. In some cases, the cushioning material 2 may be arranged according to the present invention on two or more surfaces of the lead-acid battery.
[0014]
Further, as shown in FIG. 2, lead-acid battery related parts can be accommodated in the buffer material 2. FIG. 2 shows a state in which the accommodation space 5 is provided in the cushioning material 2. An example of the lead-acid battery-related component is the liquid spout 6 or the like when the lead-acid battery is an immediate battery. When the type of the lead storage battery is 75D31L, the dimensions of the accommodation space 5 are, for example, a length of 150 mm, a width of 40 mm, and a depth of 23 mm. In this case, the accommodation space 5 may penetrate the cushioning material 2 in the thickness direction. When the accommodation space 5 does not penetrate the buffer material 2 in the thickness direction, the storage space 5 is arranged at one or more locations selected from the upper surface, the lower surface, and the side surface of the buffer material 2.
By employ | adopting the said structure, the effort which packs and conveys lead acid battery related components separately from a lead acid battery can be saved. This effect is not limited to the case where the lead storage battery is a ready-to-use battery. The reason for this is that the lead-acid battery-related parts include tools for attaching the liquid spigot 6 to the lead-acid battery, lead-acid battery instruction manuals, and lead-acid batteries as equipment in addition to the liquid spigot 6 in the case of ready-to-use batteries. This is because there are tools such as a wrench used for mounting.
However, in the case of the ready-to-use battery, the liquid spigot 6 has conventionally been wrapped and attached to the lead-acid battery. However, the above configuration can save time and space for attachment. In particular, it has a high industrial value.
In FIG. 2, the lead storage battery 1, the buffer material 2, and the liquid spout 6 are all covered with the film 3, but the film 3 may not be necessary depending on the shape of the accommodation space and the location where it is arranged. For example, there is a case where there is an accommodation space 5 that does not penetrate the cushioning material 2 in the thickness direction on the lower surface of the cushioning material 2.
[0015]
According to the present invention, in a packaged lead-acid battery, the packaging function can be exhibited without using a cardboard box , the environmental load due to the disposal of the packaging material can be reduced, and the packaging workability can be improved. .
In addition, such as a liquid outlet plug the case of ready-to-use rechargeable batteries, packaged separately from the lead-acid battery lead-acid battery-related parts, was able to avoid having to transport.
