However, the above-mentioned recycling process is costly, and on the contrary, the price is higher than the new material price. Furthermore, when different kinds of materials such as vinyl chloride steel sheets are mixed in metal waste materials, it is difficult to regenerate them.
The metal waste material is treated as waste, and there is a problem that the waste material source has to bear the disposal cost. Also, there is a demand for a method of reusing various types of plastic waste, but it has not yet been realized as a recycling system.

Accordingly, the present invention provides a weight such as a balance weight which can be recycled at low cost and can recycle metal wastes and plastic wastes of indeterminate shapes and materials, and a stage device provided with the weights. It is another object of the present invention to provide a method for manufacturing the weight.

[0013]

An embodiment of the present invention will be described with reference to the drawings.
A weight A1 as a first embodiment according to the present invention has a main body 10 and a ring-shaped member 20 as shown in FIG. 1, and the appearance of the main body 10 is circular as shown in FIG. The ring-shaped member 2 is formed at the upper end thereof.
0 is attached. The ring-shaped member 20 is used for locking at various places. The weight A1 is mainly used as a balance weight.

The structure of the main body 10 will be described in more detail. The main body 10 has metal waste materials 12a to 12e, a solidified material 14, and a mixed material 16. Here, the metal waste materials 12a to 12e have various shapes. The metal waste materials 12a to 12e are formed by cutting metal waste materials produced in various situations into predetermined sizes.

Next, the solidified material 14 is for integrating the waste metal material as a weight. As the type of the solidified material, a plastic solidified material having a small specific gravity, a molten lead having a large specific gravity, or the like can be used. As the plastic solidified material having a small specific gravity, various plastic waste materials can be used. Here, by adjusting the specific gravity of the solidified material, the total weight of the weight can be adjusted. In other words, when a solidified material having a small specific gravity is used, the effect of the filling amount of the solidified material on the total weight of the weights is reduced, which is effective for producing a weight having a small weight per unit volume. On the other hand, when a solidified material having a large specific gravity is used, the weight of the weight per unit volume can be increased by using a large amount of the solidified material having a large specific gravity because the influence on the total weight of the weight is large.

Next, the mixed material 16 has a diameter of 4 mm to 6 mm.
It is a hollow member formed by cutting a round pipe of a predetermined length into a predetermined length and crushing both ends of a round pipe piece. This mixed material 16
Is for adjusting the weight of the entire weight, and the mixed material 16 is not limited to the above-mentioned hollow material, and other members, for example, metal waste materials having a higher specific gravity than the above-mentioned hollow material can be used. Here, when the above-mentioned hollow material is used as the mixed material 16, since the hollow material has a hollow inside, the specific gravity of the hollow material itself is relatively small, and therefore the weight is reduced by using this hollow material. This is effective when it is desired to reduce the total weight. In addition, since this hollow material is obtained by pressing and crushing both ends of a round pipe piece having a predetermined length, it is possible to manufacture a piece having a constant weight and volume per piece. On the other hand, when it is desired to increase the total weight of the weights, a metal waste such as a lead-based metal having a large specific gravity may be mixed in addition to the metal wastes 12a to 12e.

Next, the weight A2 as the second embodiment
Has a main body 10 'and a ring-shaped member 20 similarly to the first embodiment, and the main body 10'
2, the main body 10 'has an outer skin 18 as a cover on its outer periphery, as shown in FIG.

The outer cover 18 is made of a form material used for manufacturing the weight A2 as it is.
When a solidified material having a low melting point is used as the solidified material 14 used for the main body 10 ′, the formwork member may be formed of an extruded plastic material, while the solidified material 14 having a high melting point is used. In such a case, the form material is formed of an iron plate or the like so as to withstand that the solidified material 14 has a high melting point. In the above embodiment, the outer skin 18 is described as using the form material as it is, but the outer skin may be attached later. In addition, the above-mentioned weight A1,
Although A2 has been described as a columnar shape, the shape is not limited to this, and an arbitrary shape such as a square columnar shape is possible.

According to the weights A1 and A2 of the present embodiment, the metal waste material is used, so that the metal waste material can be recycled. Further, since the metal waste material is used as it is without being melted, different kinds of materials such as a vinyl chloride steel plate are used. Recycling is possible even when materials are mixed. Further, since a mixed material such as a hollow material is used for weight adjustment, adjustment of the weight weight becomes easy. In particular, when a hollow material is used as the mixed material, a mixed material having a small specific gravity can be easily obtained, which is effective when the total weight of the weight is to be reduced. Further, when the hollow material is used as a mixed material, it is possible to recycle a waste pipe. Further, when a plastic waste material is used as the solidified material, it is possible to reuse various plastic waste materials that have been conventionally required. Further, since the weight of the present embodiment uses waste materials such as metal waste materials and plastic waste materials, the overall manufacturing cost can be reduced.

Further, when the outer skin is provided as in the weight A2 of the second embodiment, the appearance of the weight can be beautifully displayed, and the form material used for manufacturing the weight can be used as it is. When using as outer skin,
The labor for attaching the outer skin can be saved.

Here, the manufacturing process of the weights A1 and A2 will be described with reference to FIG. First, a metal waste material to be used is prepared (Step 001). Here, as for the metal waste material used for forming the weight, as described above, the shape is indefinite and the material is indefinite. In addition, when the size of the prepared metal waste material is too large to be put into the form material to be put, it is necessary to cut it into a predetermined size. Here, it is assumed that the weight of the weight to be manufactured is W and the volume is T.

Next, the sum of the weight and volume of the metal waste material to be put into the form material is measured (step 002). Here, the sum of the measured weights of the metal waste materials is W1, and the sum of the volumes is T1. Since the sum W1 of the measured weight of the metal waste material is equal to or less than the above W and the sum T1 of the volume of the metal waste material must be equal to or less than the above T, if W1> W or T1> T
If so, it is necessary to reduce the amount of metal waste to be input as compared with the previously prepared one.

Next, in the weight W and the volume T of the weight to be manufactured, the weight W2 and the volume T2 to be occupied by the solidified material and the mixed material are calculated (step 003). Here, W2
= W-W1, T2 = T-T1. When the outer skin 18 is provided as in the second embodiment, it is necessary to consider not only the metal waste material but also the weight and volume of the outer skin. That is, in the calculation of the weight W2 and the volume T2, the weight and the volume of the outer skin also need to be subtracted from the total weight and the total volume.

Next, the input amounts of the solidified material 14 and the mixed material 16 are calculated (step 004). That is, step 0
Since the weight and volume occupied by the solidified material 14 and the mixed material 16 are calculated in 03, the amounts of the solidified material 14 and the mixed material 16 are calculated so as to be the remaining weight and volume other than the metal waste material. For example, when the weight per unit volume of the solidified material is p, the volume per unit volume of the mixed material is q, the volume of the solidified material to be input is x, and the volume of the mixed material is y, the following calculation is performed. The formula holds. W2 = px + qy (1) T2 = x + y (2) The above x and y are calculated by the above equations (1) and (2) to mix with the solidified material. Calculate the input amount of material. When a plurality of types of solidified materials and mixed materials are used, the number of unknowns increases. Therefore, a number that satisfies the above equations (1) and (2) is selected. In addition, it is necessary to select an appropriate solidified material and mixed material so that the above formula is satisfied.

Next, the metal waste material is charged into the form material, and the solidified material and the mixed material are charged into the form material according to the input amounts of the solidified material and the mixed material calculated in step 004 (step 005). . The ring-shaped member 20 is provided in advance at the distal end of the form material so that the solidified material is fixed to the distal end when the solidified material is solidified. When the solidified material is solidified, the solidified material is taken out of the form material. In addition, as in the second embodiment, the outer skin 18
In the case of providing, a weight is used with the form material attached.

According to the above-described manufacturing method, a weight having a desired weight and volume can be accurately obtained, and the weight can be used without inferior to a conventional weight. Also, by using different specific gravities for the solidified material and mixed material,
Fine adjustment of the weight of the weight becomes possible.
