[0002]

2. Description of the Related Art Heretofore, as a method for treating waste FRP plate pieces, it has been often the case that the whole amount is made into fine powder by a device such as a crusher, a crusher, a crusher, etc.

[0003]

However, when finely powdered and processed, dust is generated very much and there is a risk of air explosion and the like. Further, the processed fine powder is a mixture of components such as glass fiber powder, resin powder, and calcium carbonate, which have a large difference in specific gravity, which causes difficulty in processing using gravity.

The present invention has been made in order to eliminate the above-mentioned drawbacks. By cutting the FRP plate into fine pieces, the generation of dust is reduced, the risk of air explosion and the like is eliminated, and gravity is maintained at the same specific gravity. It is an object of the present invention to provide an apparatus that can easily process using FRP and produces an FRP chip in which a crushed surface is exposed with jagged glass fibers, and in addition, FRP fine powder generated at the same time can be separated and collected. To do.

Urethane rubber is baked on the outer periphery of each of the rollers 5, 6, 7, and 8. This is a slip stopper for the work 1 and may be made of another material.

A roller shaft 14 is attached to the roller 5 as its axis, and the bearing unit 1
It is pivotally supported by 5,16. Bearing unit 15,
Support frames 17 and 18 for supporting 16 vertically slidably
Is provided. Springs 21 and 22 are provided between the support frames 17 and 18 and the bearing units 15 and 16 so as to urge the bearing units 15 and 16 downward.

The above roller shaft, bearing unit, support frame, and spring configurations also apply to the roller 7, and this configuration allows the rollers 5 and 7 to move vertically depending on the thickness of the work 1. There is.

The shaft 14 of the roller 5 penetrates the bearing unit 16 and is connected to the shaft of the electric motor 23. An Oldham coupling 24 is mounted between the shaft 14 and the electric motor 23.

An Oldham joint is used for the purpose of moving the roller 5 up and down according to the thickness of the work 1. However, it is not necessary that this portion is an Oldham joint, and power is transmitted by a universal joint or the like. May be.

The shaft 14 of the roller 5 has a motor 23
The bearing unit 15 is penetrated on the side opposite to the above, and a sprocket for attaching a chain is provided at the tip thereof.

A sprocket is provided at the tip of the roller shaft 33 of the roller 7 on the side of the sprocket at the tip of the shaft 14 of the roller 5, and the chain 3 is provided between the sprocket and the sprocket.
4 is attached, when the electric motor 23 rotates, the roller 5 rotates, the rotational force is transmitted by the mechanism of the chain and the sprocket, and the roller 7 rotates in the same rotation direction as the roller 5.

The mechanism of the chain 34 and the sprocket may be another mechanism such as a timing belt as long as there is no problem in strength.

The sprockets and shafts 14 and 33 described above
A collar is attached between the rollers to prevent the rollers 5 and 7 from moving in the axial direction.

Rollers 6 and 8 are rollers 5 and 7.
It is attached to the lower side of the shaft and has a shaft and a bearing unit that supports the shaft.

Next, a plurality of diamond cutting wheels 9, 9, ... Is provided with a common shaft 35, and the shaft 35 is divided into a diamond cutting wheel portion and both end portions thereof.
The parts are connected to each other by means of a friction-type connecting machine and a collar. The shaft 35 is divided into three parts to improve the workability of replacing the diamond cutting wheel 9.

The shaft 35 is supported by a bearing unit. The shaft 35 penetrates through one bearing unit X, and an electric motor 37 is inserted through a shaft coupling 36.
, And the diamond cutting wheels 9, 9, ... Are rotated by the rotational force of the electric motor 37.

Spacers are provided between the diamond cutting wheels 9 in the diamond cutting wheel portion of the shaft 35. Further, a male thread is formed in the diamond cutting wheel portion of the shaft 35, so that the diamond cutting wheel 9 and the spacer can be fixed with a nut.

By changing the thickness of the spacers, the pitch and the number of diamond cutting wheels 9 can be changed. In this embodiment, five diamond cutting wheels 9 are attached, but there is no particular limitation to five.

Diamond cutting wheel 9,
A diamond cutter guide 10 is provided in the vicinity of the upper part of 9, ... When the work 1 is cut into strips.
The vertical movement is suppressed by the rotation of 9 ,.

The structure of the diamond cutter guide 10 is such that a groove is formed in a tunnel-shaped block so that the diamond cutting wheels 9, 9 ,. It also prevents the works that have passed through the rollers 7 from overlapping each other when pushing the works that are stopped forward.

Next, the second FRP plate guide 11 intersects the strip-shaped FRP plate when the FRP plate is straightly advanced in the traveling direction.
Alternatively, the block is provided with vertical grooves so that one strip and one strip can pass separately so that the block does not travel obliquely.

The FRP plate pressing guide 12 is a tunnel-shaped block for suppressing the FRP plate from violently moving up and down when the rotary hammer 13 blows the FRP plate down.

Next, the rotary hammer 13 has a shaft 38.
The shaft 38 is pivotally supported by bearing units 41 and 42 attached to the upper portions of the two bearing receivers 39 and 40.

The electric motor 43 is connected to the shaft 38 by a shaft coupling 44. By the rotating force of the electric motor 43,
The rotary hammer 13 is adapted to rotate.

The rotary hammer 13 is provided with three heads 45 with cutting blades that laterally strike the FRP plate. The number of heads 45 with cutting blades is not limited to three, and any number may be used.

When the chip length is limited, the motor 23
The number of the cutting blade-equipped heads 45 may be changed in consideration of the number of revolutions and the number of revolutions of the electric motor 43.

Diamond cutting wheel 9,
A hopper 46 and a collection box 47 can be provided as a collection means for collecting the FRP fine powder generated at the time of cutting at a position below 9, ..., In some cases, dust can be collected while suctioning. Is.

Below the discharge port 4, a hopper 48 and a recovery box 49 can be provided as a recovery means for recovering the FRP chips that have been impacted and broken by a rotary hammer.

Incidentally, the means for collecting the FRP fine powder and the FRP chip is not limited to the above-mentioned means, and any means that can easily collect the fine powder and the chips can be used.

The FRP fine powder recovered by the recovery means can be used as a lightweight filler or the like.

[0036]

According to the present invention, since the volume ratio of processing is smaller in this apparatus than in the conventional apparatus for crushing FRP plates, the required energy can be kept low and the processing cost is low. Become. Since the FRP plate is cut into fine pieces, it is easier to convey to the next step than to make fine powder. The generation of dust is small and the risk of air explosion can be eliminated. Since it can be cut into pieces with the same specific gravity, processing using gravity can be easily performed. The finely chopped pieces are
Not only can it be used as a cast material such as artificial marble or as a filler for resin concrete, but in some cases it can also be used as a lightweight aggregate for cement concrete or the like, which is extremely useful.
