(71) Referring to FIG. 18, the edge frame (330) may have a plurality of film-adsorbing holes (335) formed through the bottom to adsorb a release film (F) when the edge frame (330) moves down and the release film (F) conveyed by the conveyor (200) is brought in contact with the bottom of the edge frame (330).

(72) Further, the edge frame (330) may further have release film holders (370), as shown in FIG. 14, to be able to pick up like tweezers the edges of the release film (F) conveyed by the conveyor (200).

(73) The release film holder (370), as shown in FIGS. 16 to 19, may have inner holder retainers (372) each coupled to a side of the lower portion of film-holding cylinders (371) and outer holder retainers (373) each coupled to the upper portion of the film-holding cylinders (371) and reciprocated by the film-holding cylinders (371) with a side in contact with a side of each of the inner holder retainers (372).

(74) The release film holders (370) may be coupled to the top of the edge frame (330) to reciprocate outward around the edge frame (330).

(75) The film-holding holes (215) may function as adsorbing holes by sucking air from above or as spray holes for blowing air upward, on the conveyor (200), so the edges of the release film (F) are floated upward by blowing air through the film-holding holes (215), whereby the release film holders (370) can pick up the edges of the release film (F) floated upward.

(76) The suction-feeding roll (400) includes the blade guide grooves (420) and the suction grooves (430).

(77) The suction-feeding roll vertical moving cylinders (410) may be coupled to both sides of the suction-feeding roll (400) to adjust the height of the suction-feeding roll (400).

(78) The suction grooves (430) are formed through the feeding roll so that a release film (F) can be adsorbed to the feeding roll when the release film (F) is unrolled and conveyed from the unwinding roll.

(79) The blade guide grooves (420) are formed in the longitudinal direction of the feeding roll so that the blade (510) can be inserted therein and cut a release film (F) on the feeding roll.

(80) The film cutter (500) includes the blade (510) and a moving blade cylinder (520).

(81) The blade (510) can cut the release film (F).

(82) The moving blade cylinder (520) has a blade (510) on a side such that the blade faces the suction-feeding roll (400) and reciprocates with respect to the suction-feeding roll (400) in order to insert the blade (510) into the blade guide grooves (420) of the suction-feeding roll (400) to cut a release film (F) that is being conveyed or take out the blade (510) from the blade guide grooves (420) after the release film (F) is cut.

(83) The film cutter (500) can move in the longitudinal direction of the suction-feeding roll (400).

(84) Accordingly, referring to FIG. 2, the release film (F) unrolled from the unwinding roll is adsorbed to the suction-feeding roll (400) and conveyed with rotation to the conveyor belt of the conveyor (200) and the conveyed release film (F) is moved to a side through the conveyor. When the release film (F) moves the length of the mold (M), as shown in FIG. 13, the moving blade cylinder (520) protrudes and the blade (510) coupled to the moving blade cylinder (520) is inserted into a blade guide groove (420) of the suction-feeding roll (400) and scratches the release film (F) conveyed and adsorbed to the suction-feeding roll (400). Thereafter, the film cutter (500) moves in the longitudinal direction of the suction-feeding roll (400), so that the release film (F) can be cut.

(85) Thereafter, as shown in FIG. 2, when the release film (F) cut in the process described above is conveyed to a target position by the conveyor (200), as shown in FIG. 3, the vertical moving cylinder (340) coupled to the edge frame (330) among the vertical moving cylinders (340) coupled to the cylinder frame (600) is moved down to move down the edge frame (330). When the bottom of the edge frame (330) moved down comes in contact with the top of the release film (F) at the target position, the release film (F) is adsorbed to the bottom of the edge frame (330) by the film-adsorbing holes (335) formed in the bottom of the edge frame (330). Then, as shown in FIG. 4, the edge frame (330) is lifted and the release film (F) adsorbed to the bottom of the edge frame (330) is picked up with the edge frame (330) from the conveyor.

(86) Thereafter, as shown in FIG. 5, the mold (M) is conveyed to a target position by the conveyor (200), and as shown in FIG. 6, when the mold (M) reaches the target position, as shown in FIGS. 7 and 8, the vertical moving cylinder (340) coupled to the middle frame (310) among the vertical moving cylinders (340) coupled to the cylinder frame (600) is moved down to move down the middle frame (310), whereby the center of the release film (F) picked up with the edge frame (330) is pressed. Accordingly, the release film (F) comes in contact with the center of the plan inside the mold (M), and thus the center of the release film (F) is bonded to the center of the plan inside the mold (M).

(87) Since the release film (F) is pressed to the center of the plan inside the mold (M) by the middle frame (310), it can be firmly bonded.

(88) In this process, the edge frame (330), as shown in FIG. 9, is maintained at the position where it has been moved up by the vertical moving cylinder (340), and then, as shown in FIGS. 10 and 11, it laterally pushes the four-directional moving frame (320) coupled to the middle frame (310) through the four-directional moving cylinders (321) such that the four-directional moving frame (320) is brought in contact with the inner sides of the mold (M), whereby the release film (M) is bonded to the inner sides of the mold (M).

(89) Thereafter, as shown in FIG. 12, the edges of the release film (F) that are irregularly placed on the edges of the mold (M) are pressed by moving down again the edge frame (330), thereby bonding the edges of the release film (F) to the tops of the edges of the mold (M).

(90) Accordingly, in the apparatus for bonding the release film for separating the artificial stone from the rubber mold according to the present invention, there is an effect capable of allowing for easy separation of the mold for manufacturing the artificial stone and the artificial stone manufactured in the mold without applying the release agent.

(91) Also, there is another effect in that it provides the apparatus for bonding the release film for separating the artificial stone from the rubber mold that can remarkably increase the lifespan of the mold for manufacturing the artificial stone.

(92) Moreover, there is further another effect in that it provides the apparatus for bonding the release film for separating the artificial stone from the rubber mold that can bond the release film to the mold for manufacturing the artificial stone up to the edges of the mold without wrinkles.

(93) Furthermore, there is further another effect in that it provides the apparatus for bonding the release film for separating the artificial stone from the rubber mold that can prevent an uneven surface of an artificial stone due to wrinkles of a release film bonded to a mold for manufacturing an artificial stone.

(94) While the present invention has been described with respect to the specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
