Description

[Detailed description of the invention] [Industrial field of application] This invention is applied to packaging aluminum sash materials consisting of vertical bars, horizontal bars, outer frame materials, etc. into individual packaging units. This relates to the binding structure of aluminum sash materials.

[Prior Art and its Problems] As is well known, aluminum sashes are made by cutting vertical bars, horizontal bars, outer frame materials, etc. of different lengths into a single aluminum sash component. It is organized. Conventionally, such an aluminum sash component unit has been packaged in a packaging form as shown in FIG. 1, for example. That is, in the conventional packaging form of aluminum sash materials, the accumulated aluminum sash materials A and S are wrapped from below with a heat-shrinkable film F, and the center lines C and L along the length direction, as well as both ends E. ，
The film was sealed with an L and wrapped on the entire surface, and in that state was passed through a shrink tunnel, and the film was heat-shrinked for packaging. however,
This conventional packaging form has the following drawbacks or problems. First of all, because it is a fully packaged form of heat-shrinkable heat-shrinkable film,
This is economically disadvantageous in that it requires a large amount of film material and requires a large amount of energy for heat shrinkage treatment. Also,
Conventional full-face packaging has weak cohesiveness, and therefore has disadvantages such as misalignment between internal products during transportation and scratches on the surface of the aluminum sash material. Furthermore, since the film is completely packaged, there are many problems such as the troublesome work of unpacking and the disposal of the film after unpacking.

[Purpose of the invention] Therefore, this invention aims to reduce the amount of packaging materials used in packaging aluminum sash materials, save resources, and save labor in packaging and unpacking operations. It is an object of the present invention to provide a binding structure for aluminum sash materials, which is intended to reduce waste later on.

Furthermore, this invention uses a plastic stretch film of a predetermined width as a binding material, which has the property of sticking to each other when in direct contact and the property of stretching and contracting in the length direction, and while applying a tensile force to the stretch film, It is a structure that unites
Aluminum sash is made by tightly and reliably binding aluminum sash materials to prevent the products from shifting, and by enclosing and bundling the ends of the products to prevent direct contact between the ends of the products, thereby preventing scratches on the aluminum sash materials. The purpose is to provide a binding structure for materials.

[Structure of the invention] In achieving the above purpose, this invention:
Specifically, at least two types of long aluminum sash materials with different length dimensions are accumulated for each type, and are bundled as at least two types of primary bundles, and then each of the above-mentioned primary A binding structure for aluminum sash materials in which the bundles are bundled together to form a set of aluminum sash constituent units, wherein the binding material for binding the aluminum sash materials is made of narrow plastic that is stretchable in the length direction. The binding material is wound at least twice in an overlapping manner around the accumulated aluminum sash material under tension in the longitudinal direction, and the binding material is wrapped around the accumulated aluminum sash material in an overlapping manner, and is bound by the binding material at least at both ends in the length direction, and when tying, the binding material is wound so that one edge side in the width direction protrudes from the end of the aluminum sash material. This is a binding structure for aluminum sash materials, in which the individually bound primary bundles are further stacked, and the collected primary bundles are tied together at an appropriate intermediate portion in the length direction.

[Description of Examples] Hereinafter, the binding structure of aluminum sash materials according to this invention will be described in detail based on specific examples shown in FIGS. 2 and 3.

As shown in Fig. 2, the aluminum sash material 1, which is the material to be bound in this invention, has different lengths as vertical bars, horizontal bars, outer frames, etc., and a set of them can be made by collecting a predetermined number of them. It is bundled and packaged as an aluminum sash component unit. The aluminum sash materials 1 of different lengths are grouped according to the same type in terms of length, and are accumulated as primary bundles 1A, 1A, and 1B of aluminum sash materials, respectively, as shown in the example shown in the figure, and are bundled by the binding material 2. be tied together. The primary bundles 1A, 1A, and 1B are further stacked together and bound with a binding material 2. In this invention, the binding material 2 has the property of airtightly adhering to each other when it is in direct contact with a flat object such as an aluminum sash material, or when films are in direct contact with each other. It is made of a plastic stretch film of a predetermined width that has the property of stretching and contracting in the longitudinal direction. The binding material 2 is a thin film, and is made of polyethylene, polybutadiene, etc., for example. It is preferable to prepare the binding material 2 in several different widths so that it can be applied depending on the purpose. The aluminum sash material 1 is bound by winding 2 to 5 times with the binding material 2 made of the above-mentioned plastic stretch film, with tension applied in the length direction of the film. The accumulated aluminum sash materials of the same type are bundled at least at both ends in the length direction. In the example shown in the figure, short aluminum sash materials 1 are stacked and bound at both ends 3, 3 to form a primary bundle 1A,
1A is formed. In this case, one edge side 4 in the width direction of the binding material 2 is the end surface 3 of the aluminum sash material 1.
It is wound so as to protrude slightly outward from a and 3a. On the other hand, the long aluminum sash members 1 are stacked and bound at both ends 5 and at appropriate positions in the length direction to form a primary bundle 1B. The binding of both ends 5, 5 is performed in the same manner as the binding of short aluminum sash materials described above. Primary bundles 1A, 1 each bound in this way
A and 1B are further accumulated and bound by the binding material 2 at appropriate positions in their length direction.

[Effects of the invention] The bundling structure of aluminum sash materials of this invention having the above-mentioned structure has the following great advantages as compared to conventional packaging forms of this type.

First of all, the aluminum sash material bundling structure devised is based on a band-shaped stretch film bundling structure, compared to the conventional wrapping structure that completely surrounds the packaged item. It can be effectively applied to wrap the packaged items by partially tying them, reducing the amount of film used, and can be said to be effective in terms of resource conservation.

Second, the aluminum sash material bundling structure devised in this invention completely eliminates the heat and electrical energy generated by heating heaters, shrink tunnels, etc. during the packaging process, compared to conventional shrink wrapping using heat. Since it is not necessary, it can be said to be suitable for energy saving. Incidentally, the first and second points mentioned above are extremely advantageous economically.

Furthermore, thirdly, compared to conventional cable ties, the aluminum sash material binding structure devised does not apply large force locally, and the binding force is dispersed over the entire width of the film. So,
No deformation or distortion of the objects to be bound occurs.

Fourth, the aluminum sash material binding structure of this invention is such that when the films come into contact with each other or with an object with a flat surface, they come into airtight contact with each other, and in addition, they have elasticity in the length direction. By applying tension in the longitudinal direction of the plastic film and wrapping it multiple times in an overlapping manner around the accumulated aluminum sash material, it is possible to create packaging with extremely high cohesiveness without the need for any heat treatment. It is possible. This improvement in binding force prevents mutual displacement of the aluminum sash materials, and prevents scratches caused by displacement, as well as flaws caused by contact between the ends of the aluminum sash materials by enclosing and binding both ends of the aluminum sash materials.

Furthermore, fifthly, as shown in FIG. 2, the aluminum sash material bundling structure of this invention is such that each aluminum sash material with different dimensions is individually accumulated and bundled, so the primary bundles 1A, 1A and 1B are When these are further integrated and bundled all at once, a space G is formed between the overlapping layers as shown in FIG. 3, thereby protecting the opposing surfaces of the two.

Sixth, with the aluminum sash material bundling structure devised, it is possible to unpack without using a knife or scissors, compared to conventional full-face packaging, resulting in superior workability in unpacking. It can be said that this method is extremely effective in that the amount of waste film after unpacking is extremely small and the amount of waste is not bulky.

Many of the above-mentioned effects can be obtained for the first time with the bundling structure of this invention,
This cannot be achieved by any of the conventional packaging methods that completely surround the packaged object, shrink wrapping by heating, packaging using cable ties, etc., or a combination thereof.
