Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for separating and collecting windshield glass from a discarded automobile.

[0002]

2. Description of the Related Art In recent years, with the increase in the number of automobiles to be discarded, it has been considered to recover useful materials such as windshield glass for recycling. However, in order to collect the window glass, there is a problem that the step of dismantling the discarded automobile becomes complicated.

Therefore, conventionally, after disposing an abandoned automobile and collecting various parts that can be easily removed, the wind glass is pressed and crushed together with the vehicle body and shredded by a shredder.

However, it is difficult to separate the glass from the shredder dust when processing as described above. Further, if the shredder dust containing the glass is directly used as industrial waste, the amount of waste increases.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for efficiently separating and recovering the window glass from the vehicle body in order to eliminate such inconvenience and to recycle abandoned vehicle window glass. To aim.

[0006]

In order to achieve the above object, the method for separating and collecting windshields of an automobile according to the present invention is a method for separating and collecting windshields from an abandoned automobile, and the roof portion of the automobile. The flat glass is pressed by a pressing member to bend the window glass itself outward from the vehicle body to shatter the window glass, and the shattered glass pieces are scattered outside the vehicle body and separated from the vehicle body. Is recovered.

Further, in the automobile window glass separating and collecting method of the present invention, the pressing member is provided with a rib protruding to the outside of the vehicle body.

[0008]

According to such means, first, the flat portion of the pressing member is brought into contact with the roof of the discarded automobile to press it toward the vehicle body. Since the upper part of the windshield of an automobile is installed so as to be inclined inward (toward the passenger compartment), when the pressing force acts on the roof part, the component force of the force that presses the roof part against the windshield itself. Causes the windshield to bend outward from the vehicle body.

When the pressing member is further pressed in the vehicle body direction in the above state, the windshield reaches the plastic limit and the windshield is shattered. Since the component force of bending the windshield outwardly acts on the window glass, the shattered glass pieces scatter outside the vehicle without entering the vehicle interior.

Since the pressing member is provided with a rib projecting to the outside of the vehicle body, the window glass curved outward from the vehicle body is pressed by the rib, so that the pressing member is easily broken.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for separating and collecting windshields of an automobile of the present invention will be described in more detail with reference to the accompanying drawings. 1 is a perspective view showing a method for separating and collecting window glass according to this embodiment, FIG. 2 is a plan view showing a positional relationship between a pressing member used in the method of FIG. 1 and a vehicle body, and FIG.
It is an explanatory sectional view shown by the I-III line.

In the method for separating and collecting the windshield of an automobile according to this embodiment, the roof member 2 of the vehicle body 1 of the discarded automobile is pressed by the pressing member 3.
The front glass 4a, the side glass 4b, and the rear glass 4c are curved outward from the vehicle body 1 by pressing with, and the side glass 4b and the rear glass 4c are crushed and cracks are generated in the windshield 4a. Then, the crushed glass pieces 5 are scattered outside the vehicle as shown by the arrow, and the glass pieces 5 are collected.

The pressing member 3 has a flat frame portion 6 abutting against the roof portion 2 and a rib 7 protruding from the frame portion 6 to the outside of the vehicle body 1. The frame portion 6 has a beam portion 8 interposed therebetween. Connected to the rod 9. The rod 9 is vertically movable by a press machine (not shown), and normally supports the pressing member 3 at a position where the vehicle body 1 is arranged below.

As shown in FIG. 2, the frame portion 6 of the pressing member 3 is a rectangular frame slightly smaller than the roof portion 2,
It is adapted to come into contact with the outer periphery of the roof portion 2.
Two ribs 7 are provided on each side of the frame portion 6 having the above-described shape.

Next, the operation of separating and collecting the window glass from the vehicle body 1 by the method of this embodiment will be described by taking the case of the side glass 4b as an example. First, as shown in FIGS. 1 to 3, the vehicle body 1 is placed at a predetermined position below the pressing member 3.
To place. Next, the press machine is operated to bring the frame portion 6 of the pressing member 3 into contact with the outer periphery of the roof portion 2 as shown in phantom in FIG. 3, and press the vehicle body 1 downward as it is.

As shown in FIG. 3, the side glass 4b is mounted so that the upper side is inclined toward the vehicle compartment 10 side. Therefore, when the roof portion 2 is pressed by the pressing member 3 and the pressing force P acts, the side glass 4b is attached to the vehicle body. A component force P ₁ directed to the outside of ₁ acts. As a result, the side glass 4b is curved outward from the vehicle body 1 as shown in phantom in FIG.

If the roof member 2 is further pressed downward by the pressing member 3 in the above state, the side glass 4b reaches the plastic limit or the portion of the side glass 4b curved outward of the vehicle body 1 presses the rib 7. It is crushed. Since the component force P ₁ acts on the side glass 4b, the shattered glass pieces 5 do not enter the vehicle interior 10 but are scattered outside the vehicle and separated from the vehicle body 1. Therefore, the crushed glass pieces 5 are collected.

The side glass 4b has been described above, but the same applies to the rear glass 4c, and the roof glass 2c is pressed by the pressing member 3 so that the rear glass 4c.
Is bent outward from the vehicle body 1 and shattered, and the glass pieces 5 are scattered outside the vehicle and separated from the vehicle body 1. Therefore, the shredded glass pieces 5 are collected.

Further, since the laminated glass is used for the windshield 4a so as not to be crushed when flying stones collide during traveling, the windshield 4a is not crushed by pressing the roof portion 2 with the pressing member 3. However, a mesh-like crack is generated by the same action as that of the side glass 4b.

Such a windshield 4a does not scatter outside the vehicle and is left on the vehicle body 1 side, but since it has a mesh-like crack as described above, the side glass 4b and the rear glass 4c are recovered if necessary. After that, it can be easily collected separately. When collecting the windshield 4a, for example, each pillar is cut at its lower part to separate the roof portion 2 and each pillar from the vehicle body 1 and only the windshield 4a is collected from the roof portion 2. Good.

The glass collected as described above is recycled for use.

[0022]

As is apparent from the above, according to the method of the present invention, the window glass can be easily separated and recovered by a simple operation of pressing the roof portion of the discarded automobile with the pressing member. Therefore, the glass can be efficiently recycled.
