Abstract

PURPOSE:To peel films adhered on the both surfaces of a SMC member simultaneously and smoothly to a great extent by making the film peeling speed of each peeling roller intermittently faster that of each feeding roller, and thereby forming the peeling angle of a film in such a way as to be within a specified range against the forwarding direction of the SMC member. CONSTITUTION:Films F and F are peeled off by peeling rollers 11 and 11 drivingly rotated by draw rollers 14 and 14 at halfway the distance to take-over rollers 12 and 12 while a SMC member S on both surfaces of which each film F is adhered, is being forwarded downward by feeding rollers 1 and 1 rotating at the direction indicated by arrow head. In this case, peeling is performed in such a way that the peeling speed of the aforesaid peeling rollers 11 and 11 is made intermittently faster than that of the aforesaid feeding rollers 1 and 1, and that the peeling angle theta of the films F and F shall be within the angle of 90 deg.<theta<180 deg. against the forwarding direction of the aforesaid SMC member S as indicated by the arrow head so as to be taken over.

Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a method for peeling off a separate film from an I-impregnated fiber sheet material (hereinafter referred to as "rSMC material"), and more specifically relates to a method for peeling off a separate film attached to both sides of an SMC material. The present invention relates to a method for simultaneously and smoothly peeling a separate film (hereinafter referred to as "film") from an SMC material.

(Prior Art and its Division) Conventionally, an SMC material sandwiched between films on both sides has been peeled off by a method shown in schematic side views in FIGS. 2 and 3.

That is, in the method shown in FIG. 2, the film F attached to both sides of the SMC material S is peeled off at an acute angle along the roller A surface after passing between the feeding rollers A, and the SMC material after peeling is S hung down and was taken off by a take-off roller (not shown).

In addition, in the method shown in FIG. 3, peeling rollers B, B are arranged below the feeding rollers A, A, and the film F is removed.

After passing between the peeling rollers B and B, F was peeled off at an acute angle along the surface of the roller 8, and the SMC material S was pulled downward.

However, in both of the methods shown in FIGS. 2 and 3 above, the film F
, When F is peeled off, the adhesive timing of the film F tends to shift between the front and back sides, and the SMC material S is biased to one side as shown by the broken line in the figure, and the SMC #S is rolled up with the film F into the lower take-up roller. It was easy for troubles to occur where work had to be interrupted.

(Means for Solving the Problems)) The present invention solves the above problems, and its gist is as follows:
While the resin-impregnated fiber sheet material sandwiched between separate films on both sides is sent out by a feed roller and reaches the take-up roller, the peeling angle θ of both separate films is set faster than the above separation and with respect to the feeding direction of the sheet material. This is a method for peeling a separate film of a resin-impregnated fiber sheet material, characterized in that peeling is performed intermittently in the range of 90° x θ x 180°.

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 shows a schematic side view of the method for peeling off a film of an SMC material according to the present invention.

A material in which film F is pasted on both sides of SMC material S,
While being fed downward by the feeding rollers 1, 1 rotating in the direction of the arrow until reaching the take-up rollers 12, 12,
The films F, F are rotated faster than the peeling roller 1.1 driven by the winding roller 14.14, and the peeling angle θ of both films F, F is set relative to the sending direction of the SMC material S shown by the arrow. , 90°<θ to 180°.

That is, the device used in the present invention has a stripping roller 11 placed below the feeding rollers 1, 1 and at a symmetrical position as shown in FIG.
, 11, a tension roller 13゜13 and a take-up roller 14.14 are arranged oppositely, pressure sensing switches 2, 2 are arranged inside the peeling rollers 11, 11, and a take-up roller 12゜12 is installed at the bottom. This is a device that must be installed.

The SMC material S with double-sided film is hung in the direction of the arrow between the feeding rollers 1 and 1 from above the above device.
While winding up the SMC material, it is peeled off by the peeling rollers 11, 11 via the tension roller 13. The switches 2 and 2 are arranged so that the peeling angle θ of the peeled films F and F is as shown by the solid line in the figure.
When the angle is 90° with respect to the feeding direction of SMC material S,
The increased contact pressure with the film F is sensed and the switch is turned OFF, stopping the drive of the take-up roller 14.14 and making the take-up roller 14.14 free.

Then, when the peeling angle θ of the film F fed out from the feeding rollers 1, 1 is in the range of 90° to θ<180°, the pressure sensing switches 2, 2 are activated before the SMC material S reaches the take-up rollers 12°12. , senses the weakened contact pressure with the film F and turns on, drives the take-up roller 14.14 to peel off the films F and F as shown by the broken line in the figure, and the speed of the peeling roller 11.11 is increased. is faster than the speed of the feeding roller 1°1, so when the peeling angle θ of the film F becomes 90° with respect to the feeding direction of the SMC material S, as shown by the solid line in the figure, the switch is turned OFF and the above operation is performed. The film is repeatedly peeled off intermittently.

(Effect of the invention) Since the present invention has the above configuration, it has the following effects.

Adjust the peeling angle of the tape from 90 to the feeding direction of the SMC material.
By intermittently winding the film in a 180° range, there is no problem such as the SMC material being biased to one side or being wound together with the film into the take-up roller, as in the past, and both sides of the SMC material are The attached film could be peeled off at the same time and extremely smoothly.
