FIG. 3 shows a tape guide member 3 and a suction head 6.
FIG. Therefore, the operation of this label sticking apparatus will be described below with reference to FIG. First, the tape guide member 3 stands by at the standby position at the end of the arrow B direction in FIG. 4, the suction head 6 is moved to the arrow A direction side in FIG. It has been moved to an adjacent peeling position. Further, when the tape guide member 3 is moved to the standby position, the winding operation on the winding shaft 2 side is locked by a means (not shown) so that the winding operation cannot be performed, and a new tape is fed from the supply shaft 1 side. After the tape 9 is pulled out by the tape guide member 3 and the label 8 is arranged below the suction head 6, the tape 9 on the pull-out side is locked by means not shown in this state.

Next, vacuum suction of the suction head 6 is started. Then, the label 8 on the tape 9 is sucked by the suction head 6 through the main suction hole 11 and the sub suction hole 12 (FIG. 3).
(See (a)). Next, when the lock on the winding shaft 2 side is released and the winding of the tape 9 is started, the tape guide member 3 is urged by a spring (not shown) along with the winding of the tape by the winding shaft 2. And starts moving in the direction of arrow A (see FIG. 3B). And the tape guide member 3
When the edge portion 3a of the label comes under the label 8, the cutting (peeling) of the label 8 is started by the edge portion 3a. Further, in the initial state of being peeled off, as shown in FIG. 3C against the suction force of the auxiliary suction hole 12, a part 8 a on the leading end side of the label 8 has a lower surface 3 of the tape guide member 3.
Although it is about to be caught in the c side, the part 8a of the label 8 is sucked by the suction head 6 by vacuum suction at the part of the auxiliary suction hole 12.
It is returned to the side (see FIG. 3D). In this state, when the tape 9 is further wound and the tape guide member 3 is moved in the direction of arrow A in FIG. 4, the label 8 is peeled off from the tape 9 and transferred to the suction head 6 side (FIG. 3). (E),
(See (f)).

Further, the suction head 6 which has received the label 8
Is moved in the direction of arrow U by the operation of the cylinder 14, and then is carried to a predetermined attaching position by the slider 15.
At the attaching position, the cylinder 14 is operated again so that the label 8 attached to the adsorption head 6 is attached to the attaching stage 7
It is pressed against the parts in the tray 17 arranged above and the vacuum suction is released. As a result, the label 8 on the suction head 6 side is attached to the component side. And
The suction head 6 that has been attached with the label 8 has a slider 15
Then, the cylinder 14 is operated to return it to the first peeling position again.

On the other hand, on the tape guide member 3 side, the winding shaft 2 side is locked and the supply shaft 1 side is unlocked. Then, the tape guide member 3 is returned to the initial position (see FIG. 3A) while pulling out the new tape 9 from the supply shaft 1 side by the return force of the biasing means, and the label 8 is placed under the suction head 6. It will be placed in the state. By repeating this, the label 8 can be sequentially attached to the components arranged in the tray 17 on the attachment stage 7.

Therefore, according to the label sticking apparatus of the present embodiment, the peeling of the label 8 is started at the edge portion 3a, and the leading end portion 8a of the label 8 is likely to be pulled into the surface opposite to the edge portion 3a. This tip part 8a
Since the peeling proceeds while being sucked and returned by the auxiliary suction hole 12, the leading end portion 8a of the label 8 is drawn into the surface on the opposite side of the edge portion 3a until the position corresponding to the main suction hole 11 is peeled. There is no need to say that you are going away. As a result, reliable peeling is possible and also the peeling speed and the like can be accelerated.

Incidentally, the auxiliary suction hole 12 provided in the suction head 6
Is not limited to the above structure, and may be variously modified according to the shape of the label 8 or the like. For example, the structures shown in FIGS. 5 to 12 are conceivable. 5 to 12, the reference numeral 11 indicates the main inhalation portion, and the reference numeral 12
The sub-intake part indicated by is, for example, an oval shape, a gourd shape, a daruma shape, an oval shape, which is not necessarily circular, and further, as shown in FIGS. It does not matter even if it is provided with 12. An arrow in FIGS. 5 to 12 indicates the traveling direction of the tape 9.

[0021]

As described above, according to the present invention,
When the peeling of the label starts at the edge part and the tape is folded back to the back side of the edge part and is drawn in, the tip part of the label is about to be drawn in on the surface opposite to the edge part. Since the peeling proceeds while adsorbing and returning the part at the sub-inhalation hole, it is said that the label is drawn into the surface on the opposite side of the edge portion until the position corresponding to the main suction hole is peeled off. Can be eliminated, reliable peeling can be performed, and the peeling speed can be increased.
