Abstract

PURPOSE:To realize the packaging structure difficult to break even with a large load exerted on the corners of a group of batteries stacked on a pallet by winding up the batteries with a packaging lap having a number of continuous gatherings lengthwise. CONSTITUTION:A wide continuous strip of synthetic resin lap of a packaging part 4 wound up around a pallet and a group of batteries thereon has thereon a plurality of gatherings 5 extending lengthwise. Such gatherings can be formed easily by winding up the lap in such a manner as to make it narrower than its original width. As an effective alternative winding up method, the lap is stretched widthwise before use. More specifically, the lap is first stretched widthwise by a convexly-shaped roller 6 and contracted widthwise by moving a concavely-shaped roller 7 with an up-and down motion and this method is left to one discretion. The gatherings 5 formed on the lap resemble the structure made up of a bundle of strong ropes and has a stronger face than when the stretched resin laps are used in a plurality of sheets and this lap is rigid in packaging strength, reliable and suitable for use in transit.

Description

DETAILED DESCRIPTION OF THE INVENTION Five Industrial Application Fields The present invention relates to a storage battery package in which a plurality of storage batteries are loaded on a pallet and packed.

BACKGROUND OF THE INVENTION Lead-acid batteries are heavy items and contain liquid inside, so they are one of the items that requires care when being transported.

Of course, since it is transported, it is placed on a pallet.
It is necessary to use a packaging method that prevents the loaded items from shifting.

When transporting batteries, batteries are not always carried bare; instead, one or more batteries may be packed in cardboard boxes, etc., and the entire package is slippery and often causes the load to collapse due to inertia when the truck suddenly stops or curves. Yes, special attention is required.

One way is to integrate them so that they do not shift, but the problem is how to specifically protect a group of small, angular, heavy objects.

As a method of integration, Japanese Utility Model Application No. 61-88659 discloses a package in which a bare battery group and a pallet are integrally molded with a synthetic resin film. The purpose of this is to save the trouble of packaging the batteries.The bare cell foam is secured by tightening each row of batteries with something similar to a band, and then a synthetic resin film with the tip fixed to a pallet is spread out to further wrap the top surface. A configuration is disclosed that wraps around the opposite side to form a surface protector.

Problems to be Solved by the Invention However, this conventional technique is insufficient to realize a package with good workability and high strength.

First of all, if you spread out the film and use it, it tends to tear at the corners of objects. Naturally, consideration must also be given to how the forklift will accommodate pallets.

The object of the present invention is to obtain a highly strong package particularly suitable for transportation, and in particular to realize a structure that is resistant to tearing even when a large load is applied to the corners of a group of batteries loaded on a pallet.

The purpose is also to make the protective wrap more difficult to tear in areas where the dimensions of the battery group and the pallet do not match, and to prevent the package from being broken abnormally due to indiscriminate insertion of the fork of a forklift into the sealed area. That is.

Means for Solving the ProblemsThe present invention, as a specific measure to solve these problems, has a plurality of storage batteries loaded on a pallet equipped with a fork receptacle for a forklift, and the top surface of the group of batteries is almost completely covered with the battery. In a package consisting of a packaging part that is opened and rolled up with a wide continuous synthetic resin wrap covering almost the entire side surface, the wrap of the rolled-up packaging part is wrapped with a large number of continuous wrinkles in the length direction. This is a storage battery package characterized by the following.

Also, the wrap at the fork insertion part where the fork is inserted is rolled up so as to provide a gap in the height direction.

Function Since the present invention has the above-described structure, it has elasticity against stress at corners and is resistant to tearing due to inertial force during transportation. Also, the wrinkles formed on the wrap have a structure similar to that of strong ropes gathered together, which is stronger than using multiple sheets of expanded resin wrap. In addition, this kind of structure that has both strength and looseness allows the fork insertion port to be partially opened, so that even if the fork gets caught in the wrap, it will escape and only damage a part of the tightened wrap, and the width of the other parts will be reduced. In particular, the area near the fork insertion opening is important for maintaining the integrity of the package because it is the area where the force of integrating the battery and pallet is applied.

Note that the present invention is particularly effective for transporting batteries packed in slippery cardboard packaging or Shinylink packaging that are placed on storefronts as products.

Example The present invention will be described below with reference to Examples.

FIG. 1 is a diagram showing an embodiment of the present invention. Reference numeral 1 is a pallet provided with a fork insertion port 2, and 3 is a storage battery or a small package in which the storage battery is wrapped in cardboard or in a cylindrical box. These are stacked on a pallet 1 in multiple stages. Reference numeral 4 denotes a roll-up packaging section in which a wide and continuous synthetic resin wrap is rolled up around a pallet and a group of storage batteries thereon, and each of these wraps is provided with a plurality of wrinkles 5 extending in the length direction thereof. Such a configuration can be easily formed by winding the lamp to a narrower width than the original lamp width.

In addition, there is a method of first stretching the lamp in the width direction using a convex roller 6, etc., and then rolling it up and down with the concave roller 7 to reduce the width. It is an effective means to realize the body and can be selected arbitrarily.

Fig. 2 shows another embodiment of the present invention, in which a pallet is placed on a rotatable table 8, and the wrap is wrapped from a fixed direction while rotating the rotary table by making it easier to form wrinkles from a certain position. It shows how it goes. At this time, the edges of the pallet are made to match the edges of the battery group. In other words, since the battery group at the bottom needs to be integrated into the pallet 1, it is desirable that they match.

Moreover, FIG. 3 is a diagram showing the vicinity of the fork insertion opening. This is an example in which a pallet 1 is rolled up while forming wrinkles 5 on the wrap 4 and providing gaps in the height direction of the insertion opening 2 of the pallet 1 according to the present invention. Such a configuration can be more reliable than a fully taut wrap. In addition, even if the battery should be hit by the fork of a forklift, it will be easily bounced off by the tip of the fork and will not spread in the width direction even if it is broken through, thereby increasing the safety of integrating the storage battery group into the pallet. Note that it is optional to use a cushioning material such as cardboard between the batteries in each stage.

In addition, in the example, there is hardly any plastic wrap wrapped around the top surface of the loaded storage battery, but this open part is important to prevent oxidation corrosion of the balls caused by confining batteries containing liquid in a closed room, and protects them from contamination in the unlikely event of contamination. If a protective sheet or the like is used for this purpose, it is preferable to make at least a hole in a part of it and place it on top of the battery group, and apply the present invention in this state. Note that the ends of the wrap may be fixed to a part of the pallet, the object to be packed, or the packaged object by any method such as pinching, wrapping, or pasting.

Effects of the Invention Since the present invention has the above-mentioned structure, the packaging strength is strong, the reliability is high, and the industrial practicality of the present invention is extremely high as a storage battery package suitable for transportation.
