２を貼付するものである。In front of the advancing direction F of the label piece 2 to be peeled off, a label suction plate 6 supported by an arm 10 stands by. The label suction plate 6 is formed in a box shape having a hollow portion 7, and a plurality of small suction holes 8 communicating with the hollow portion 7 are formed in the lower suction surface 6A.
On the upper surface of the label suction plate 6, one end has the hollow portion 7
There is provided a hose 9 which communicates with and has the other end connected to a suction device (not shown). And suction device (not shown)
The negative pressure is applied to the hollow portion 7 of the label suction plate 6 through the hose 9 to suck and hold the label piece 2 peeled by the peeling plate 5 on the suction surface 6A via the suction hole 8. The label piece 2 is attached to a predetermined position of the article to be attached 12 carried by the conveyor 11 provided separately by the descending operation of the arm 10.

ないものであった。However, the negative pressure of the hollow portion 7 of the label suction disk 6 is set in consideration of the suction / holding force of the label piece 2 on the suction surface 6A. Since the corresponding high pressure was continuously applied, the label piece 2 may be adsorbed and held by the label adsorber 6 while the label piece 2 is not advancing to the predetermined position S in the advancing direction F. That is, as shown in FIG. 5, when the label piece 2 advances in the traveling direction F, the suction hole 8A on the upstream side is first closed (the solid line position of the label piece 2), and the label piece 2 advances to the downstream side. As the suction holes 8B, 8C, and 8D gradually close, the hollow portion 7 has a constant high negative pressure, so that the suction force gradually increases as the suction holes 8 are closed. 8A, 8B, 8C, 8D are all label pieces 2
When the label piece 2 is blocked by, the label piece 2 stops at the suction hole 8D (the imaginary line position of the label piece 2) and does not advance to the predetermined position S.

On the other hand, the label piece 2 is displaced to the outside (right side in FIGS. 4 and 5) of the label suction disc 6, and the rear end of the label piece 2 is partially temporarily attached without being completely peeled from the mount 1 on the peeling plate 5. Even when the arm 10 is lowered and the sticking operation is started by moving the arm 10 downward, the label piece 2 is not well separated from the mount sheet 1, and the label piece 2 is pulled by the mount sheet 1 and is attached to the label suction plate 6.
As a result, the label may not be accurately attached to the predetermined position of the object to be attached 12, as a result of the further displacement in the suction / holding position.

のである。The microcomputer 30 includes the label detecting sensor 26, the air pressure control device 27, and the solenoid valve 2.
8. The pressure sensor 31 and the control panel 32 are connected to control the operation of each of these devices. That is, when a signal from the label detection sensor 26 that the label piece 20 has reached the predetermined position S is received, the setting condition of the control panel 32 is changed to X which sets the voltage to 10 V and the air pressure control device 27 is flowed. The compressed air is made to have a high pressure, the compressed air having the high pressure is sent to the vacuum generating device 29 through the electromagnetic valve 28, and the arm 10 is controlled to descend. When the sticking of the label piece 20 to the adherend 12 is completed, the electromagnetic valve 28 is closed and the compressed air sent to the vacuum generator 29 is once set to zero, and the label piece 20 stuck to the adherend 12 is used for the label. The label suction plate 21 is easily released from the suction plate 21, and the label suction plate 21 is raised. The setting condition of the control plate 32 is changed to Y for setting the voltage to 1V to reduce the pressure of the compressed air flowing through the air pressure control device 27,
It waits for the next label piece 20 to be peeled from the peeling plate 5.

Search in the low pressure / cm 2, the solenoid valve 28, a vacuum generator 29
And is discharged as exhaust air H via. At this time, the negative pressure in the hollow portion 23 of the label suction disk 21 is the vacuum generator 29.
Since the pressure is set to a low pressure corresponding to the pressure of the label plate 20, the label piece 20 sent from the peeling plate 5 in the traveling direction F is sucked and held by the label suction plate 21 to the extent that the label piece 20 is not sucked and held at the predetermined position S. The suction surface 21A is smoothly moved toward.
Further, since the air is blown from the auxiliary nozzle 35 toward the label piece 20, the label piece 20 that is sucked to the extent that it does not fall does not drop from the label suction plate 21. Then, even if the suction hole 24 is gradually closed toward the predetermined position S, the suction surface 21A is not strongly attracted, so that the transfer force of the mount 1 that is turned by the peeling plate 5 without stopping midway. It reaches the predetermined position S.

The label suction plate 21 has a strong suction / holding force, so that the label piece 20 is strongly sucked / held so as not to move further at the predetermined position S.

By setting the step setting conditions, and further by switching the setting conditions of the plurality of steps according to the change in the negative pressure of the hollow portion 23 of the label suction disk 21 sent to the microcomputer 30 by the pressure detection sensor 31, the hollow portion 23 It is also possible to correct the negative pressure to an appropriate pressure.
