Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 is a configuration diagram showing a configuration of an attaching member provided in the automatic peeling device of the present invention. As shown in the figure, the sticking member is composed of a soft member 1 made of malt plane, mylar, or the like, an adhesive 2 attached to one surface of the soft member 1, and a peeling member superimposed on the soft member 1 via the adhesive 2. The paper 3 is fixedly fixed. Note that the release paper 3 has a slit (a cut or the like) substantially at the center A. FIG. 1 shows an automatic peeling apparatus according to a first embodiment of the present invention in which such a sticking member is provided to automatically peel the release paper 3 from the soft member 1. As shown in FIG. 1 (a), in the automatic peeling device of this embodiment, a gripping mechanism 4 for gripping an attaching member, and a tilt mechanism (not shown) for bending the longitudinal direction of the attaching member into a "<" shape. )
With the holding mechanism (bending mechanism) 4 holding the sticking member by, for example, vacuum suction, both sides of the central part A of the sticking member are tilted about 5 ° from the horizontal in the direction of B shown in FIG. Tilt. For example, by raising the gripping mechanism 4 upward or lowering the tilt mechanism, the central portion A of the attaching member is pressed from above into the central groove of the tilt mechanism provided with the dogleg base. Further, as shown in FIG. 1 (b), the left and right gripping mechanisms 4 are brought closer to the direction C by a driving mechanism (not shown) while tilting (tilting), and the sticking member is bent from the central portion so that both sides of the central portion are bent. Contact. Then, the release paper 3 lacking in flexibility compared to the soft member 1
Is released from the slit portion of the central portion A, and a released portion D is formed as shown in FIG. Subsequently, the release portion D is gripped by the release paper gripping mechanism 5 with, for example, an attraction force as shown in FIG. 1B, and the respective release paper gripping mechanisms 5 are not shown left and right (in the direction shown by the arrow). The release paper 3 is peeled off by being moved by the moving mechanism (see FIG. 1C). Thereafter, the gripping mechanism 4 is returned to the original position, the flexible member is stretched flat, and the process proceeds to the next step (for example, a sticking step). In this manner, according to this embodiment, a part of the release paper is peeled off before bending by the release paper gripping mechanism, so that poor gripping and suction does not occur and the peeling speed can be increased.

FIG. 3 is an explanatory view of an automatic peeling device according to a second embodiment of the present invention. As shown in the figure, the automatic peeling device of this embodiment has the configuration of the first embodiment,
A protruding member 6 having a sharp tip that presses against the bent portion of the attaching member from the back is provided.

The sticking member gripped by the gripping mechanism 4 and transported to the peeling station is sandwiched between the lower holding member 7 having the suction mechanism and the gripping mechanism 4, and the protrusion member 6 a having a triangular end face is formed. The pressing portion pushes out the soft member 1 in the bending direction E from the upper portion, and in synchronization therewith, moves the left and right gripping mechanisms 4 and the lower holding member 7 in the direction C in which the paired two approaches. Then, since the central portion of the attaching member is bent at an acute angle by the initial projecting member 6a, the release paper 3 is released from the adhesive 2 at the central portion A (see FIG. 1). Further, the projecting member 6a is rotated,
The flat portion of the protruding member 6a which was on the upper side is set to the lower side in the figure. Then, secondary bent portions F are generated on the left and right, and the release amount of the release paper 3 increases. Therefore, the release paper 3 is sandwiched and gripped by the release paper gripping mechanism 8, moved outward, and peeled. Thus, according to this embodiment, since a part of the release paper can be more effectively peeled before the suction by the release paper gripping mechanism, the gripping and suction failure can be further reduced, and the peeling speed can be further increased.

As shown in the figure, this automatic peeling device includes a roller mechanism 12 for pressing the release paper portion side of the sticking member gripped by the gripping mechanism in addition to the configuration of the second to fourth embodiments. The roller mechanism 12 includes a pair of squeezing rollers 13 as elastomer rollers (rollers made of an elastic material) whose rolling resistance can be adjusted (see FIG. 6A). (See FIG. 6B). Then, a shear stress is generated by the resistance of the ironing roller 13 during the passage, and the release paper 3 is released from the adhesive material 2 at the release portion D. Eventually, the free part D
Alternatively, the tip of the attaching member reaches the release paper gripping portion 15, but at that time, the arm 16 and the ironing roller 13 are connected by a clutch (not shown), and the rotation of the ironing roller 13 starts to wind the release paper 3 into rotation. Peeling is performed as shown in FIG. When the pasting member has passed between the ironing rollers 13, all the release papers 3 have been peeled off. A locking piece 16a for locking the end of the release paper 3 at the lower end of the arm 16 may be provided and hooked.
The ironing rollers 13 on the left and right sides can be adjusted in pinching force by a spring 14 constituting the roller mechanism 12. Thus, according to this embodiment, since the cutting of the release paper is promoted by the ironing, a part of the release paper can be released more effectively before the suction by the release paper gripping mechanism, and therefore, the gripping suction Defects can be further reduced, and the peeling speed can be further increased. FIG. 7 is an explanatory view of an automatic peeling device showing a sixth embodiment of the present invention. As shown in the figure, this automatic peeling device includes a brush roller 21 which is a mechanism for rubbing the tip of a bent portion in addition to the configuration of each of the above embodiments. The bent portion J is rubbed in order to cope with the case where the central portion of the release paper 3 is in an incompletely cut state. At this time, the rotation direction is reversible so as to be able to cope with both the left and right sides.

FIG. 8 is an explanatory view of an automatic peeling device showing a seventh embodiment of the present invention. As shown, in addition to the configuration of the first to fifth embodiments, this automatic peeling device has a pair of (at both sides of a central portion of the release paper 3 protruded by the protruding member 6) a tip of a bent portion. A peel roller 23 is provided. At least the peripheral surface of the peeling roller 23 shown in FIG. 8 is made of an adhesive material, or has a structure in which a large number of suction pads 24 are provided on the circumference as shown. Then, a shear stress is generated between the release paper 3 and the adhesive 2 by the rotational resistance of the release roller 23 having such a configuration and the rotational resistance due to the pinching force of the spring 25. Further, the pinching force generates an adhesive force between the release roller 23 and the release paper 3. The separation of the release paper 3 is promoted by such shear stress and adhesion. In addition, according to the width of the attaching member, both of these forces are adjusted by an adjuster (not shown) of the spring 25 and the resistance adjusting knob 26 to adjust the peeling force. FIG. 9 is an explanatory view of an automatic peeling device showing an eighth embodiment of the present invention. As shown in the figure, this automatic peeling device does not include a tilt mechanism, but includes a release paper gripping mechanism 31 having a return mechanism composed of a torsion spring, and a moving mechanism for moving the release paper gripping mechanism 31. The release paper gripping mechanism 31 includes a suction pad 32 and a neck 33 for holding the suction pad 32. The release paper 3 is sucked and peeled by the suction pad 32 facing the sticking member.
The release paper gripping mechanism 31 is provided with a torsion spring for urging the suction pad 32 and the neck 33 in a direction K (see FIG. 9 (a)).
In the state where the release paper gripping mechanism 31 is stationary, the suction pad 32 is raised as shown in FIG. 9A, but the suction pad 32 holds the release paper 3 as shown in FIG. When the release paper gripping mechanism 31 is moved in the horizontal direction L while being sucked and gripped, a moment M acts due to the peeling resistance and the bending resistance of the release paper 3, and the suction pad 32 grips the release paper 3 always vertically (FIG. 9 (b)). In this embodiment,
By providing a sensor (not shown) for detecting the inclination of the suction pad 32 and the neck 33, the quality of the suction state is detected. As described above, if normal, the suction pad 32 always grips the release paper 3 vertically, so it is possible to determine whether or not the release paper is vertically gripped by detecting the inclination. If it is an error. Since such a detection method has no hysteresis like a diaphragm-structured sensor for detecting a negative pressure in a vacuum pipe section, detection accuracy can be improved. Thus, according to this embodiment, since the suction pad always grips the release paper vertically, the frequency of occurrence of poor suction can be reduced, and the method of realizing the same is simple.

FIG. 10 is an explanatory view of an automatic peeling device showing a ninth embodiment of the present invention. This automatic peeling device includes a dryer and a heater as a temperature raising means for raising the temperature of the attaching member before the peeling operation, in addition to the configuration of the automatic peeling device of each of the above embodiments. As shown in FIG. 10, for example, warm air is sent to the bent portion by a dryer 36 provided at the center to warm the bent portion, thereby weakening the adhesive force of the adhesive material 2. If a dryer of about 300 W is used, the effect of weakening the adhesive force will be exhibited in about 10 seconds,
Of course, it can be adjusted depending on the material. It is also effective to embed the heater 37 in the protruding member 6 to warm the bent portion. Although the dryer 36 and the heater 37 are shown in FIG. 10, either one of them may be used. Thus, according to this embodiment, the adhesive force of the adhesive 2 is weakened, and the release paper 3 can be more easily peeled off.
