Description

[Detailed explanation of the idea] The present invention relates to a peeling and cutting device for SMC material.

When molding FRP products, semi-cured molding with low adhesiveness and easy handling is made by impregnating glass fiber with unsaturated polyester resin or epoxy resin containing hardening agents, mold release agents, fillers, coloring agents, etc. Press molding may be performed using sheet material.

The SMC material used in this molding method involves spraying chopped glass strands and resin on a separate film, overlaying the separate film on top of this, gluing both edges of both films, and then applying the resin. Obtained by curing to a semi-cured state with weak tack.

When this SMC material is used, it is cut into predetermined dimensions,
The separate film is peeled off.

By the way, when peeling and cutting the separate film when using the above-mentioned SMC material, if the cutting is performed after peeling the separate film, there is no need for troublesome peeling of the separate film from the cut end surface, which is advantageous in terms of work.

However, since the glass fiber-containing resin sheet material after peeling off the separate film still has considerable adhesiveness, the sheet material 11' is supported in a suspended state without contact, as shown in FIG. It is necessary to cut it.

In this case, the sheet material 11' is cut using a normal butt-type cutter 4'.
When cutting the glass chopped strand, the entire weight of the sheet material acts on the uncut section a' with a small thickness just before cutting, and the cut section is torn off. Coming out is inevitable.

After cutting, the sheet material may have to be handled directly by hand, but as mentioned above, since the glass fibers protrude along the entire length of the cut edge, it is necessary to handle the sheet material directly by hand. It is unavoidable that the product will get stuck in the body, making it dangerous for work.

The peeling and cutting device for SMC material according to the present invention was devised in view of the above points, and includes an intermittent drive roller that feeds out a resin-impregnated fiber sheet material sandwiched between separate films, and a separate film at the exit of the roller. A winding bobbin that pulls and peels off the separation film and winds it up, and a chain cutter that cuts the resin-impregnated fiber sheet material in a suspended state after peeling off the separate film when the delivery roll stops. It is.

The present invention will be explained below with reference to the drawings.

In FIG. 1, 1 is an SMC material, and a resin-impregnated fiber sheet material 11 is sandwiched between separate films 12 and 12.

2 is an intermittent drive roller, and the SMC material 1 is sent out intermittently.

3, 3 is a winding bobbin, and the separate film 12.12 of the SMC material immediately after passing through the roll 2 is pulled off by the winding torque of the winding bobbin 3, 3, and is wound on the bobbin 3, 3. .

4 is a chain type cutter, and as shown in Fig. 2, the fixed blade 4
1 and a movable blade 42, and the movable blade 42 is rotated by a cylinder 43.

The suspended resin-impregnated sheet material 11 fed from the roll 2 is cut by the cutter 4 when the roll 2 is stopped.

FIG. 2 shows the state in which the resin-impregnated sheet material 11 is cut by the chain type cutter 4. The hanging weight of the sheet material 11 is supported by the uncut peak portion a, and while the cross-sectional area of the peak portion a is large, There is no tearing of the cut portion due to the weight of the sheet material 11.

As the cutting progresses and the cross-sectional area of the uncut ridge portion becomes smaller, the cut portion is torn off, but this is a very small ridge portion at the final stage of cutting.

Therefore, the above-mentioned protrusion of the chopped glass strand due to tearing off of the cut portion can be limited to the very end of the cut portion.

As described above, according to the SMC material peeling and cutting apparatus according to the present invention, a resin-impregnated glass fiber sheet material can be cut while keeping the protrusion of the glass fibers at the very edges during cutting.

Therefore, the cut sheet material can be handled safely without the danger of the glass fibers getting stuck to the operator.

Furthermore, since the separate film can be collected in long lengths, it is advantageous for the use of waste materials.

Furthermore, although cutting is performed after peeling off the separate film, there is no need for the troublesome work of peeling off the separate film after cutting.
