There is. Therefore, even if the pressing rod 52 is pulled back upward by the action of the elastic body 54, the shock absorbing force is absorbed by the cushioning body 58, and it is possible to endure long-term use.

Next, the operating condition of this embodiment will be described. First, as shown in FIGS. 1 and 2, the winding material of the label continuum 12 is attached to the winding reel 14,
The label continuum 12 is connected to the roller 2 of the label issuing device 10.
6, through the label detector 16 and the thermal transfer device 18,
Release paper 30 of the label continuum 12 by reaching the peeler 20
Is folded back at the tip of the peeling device 20 and wound by the take-up reel 24 via the label feed roller 22 and the like.

The label 28 in the label continuum 12
Is detected by the label detector 16 by sandwiching the release paper 30 between the rubber roller of the label feed roller 22 and the roller, and then the image lines such as characters, numbers and figures are transferred to the label 28 by heat. The part is the thermal transfer device 18
Is transferred to near the thermal head.

The transferred label 28 is brought into contact with the thermal transfer ribbon 32 by the thermal transfer device 18, and the thermal head is placed at the contact portion between the label 28 and the thermal transfer ribbon 32. The thermal head is made to work by bringing the head part of the above into contact, and thermal transfer can be performed by the thermal head.

At the time of the thermal transfer, the thermal transfer ribbon 32 is fed by the ribbon feed reel in the same direction as the label 28 is transferred, and is fed by the ribbon take-up reel in the same direction as the label 28 is transferred. The label 28 is wound around, is in contact with the label 28, and is transferred at the same speed as the transfer speed of the label 28.

At this time, the speed at which the label 28 is transferred during the thermal transfer is faster than the speed at which the adherend A is transferred by the transfer means 80, which will be described later, because the thermal transfer is performed on the label 28 by the thermal head. Become.

The label 28 transferred at the above speed is
It is peeled from the release paper 30 by the peeling device 20 and is fed to the suction plate 36 side of the label suction box 38. The delivered label 28 is suction-held on the lower surface of the suction plate 36 by the negative pressure generated by the action of the suction blower 42.

Next, the extrusion device 60 operates, and the extrusion device 6 is operated.
When the rod 64 of the actuator 62 of No. 0 rapidly descends, the lower surface of the holding portion 66 causes the buffer body 58 to move.
Is pressed, the pressing rod 52 of the pressing device 50 is rapidly lowered in parallel with the downward movement of the rod 64 via the buffer 58.

Then, the rod 64 of the actuator 62
70 provided near the lowermost end of the stroke
Then, the lowermost surface of the holding portion 66 hits, and the descending motion of the rod 64 suddenly stops.

On the other hand, the pushing device 60 holding the pressing rod 52.
Of the pressing rod 52 lowered in parallel with the downward movement of the holding portion 66 of the
Is further lowered as it is against the elastic body 54 by the inertial force of the pressing rod 52, and pushes the label 28 suction-held on the lower surface of the suction plate 36,
The surface of the pressure-sensitive adhesive layer is brought into contact with the upper surface of the adherend A conveyed by the conveying device 80 and is adhered to the adherend A.

At this time, since the label pressing portion 56 made of a flexible material is formed in the lower part of the pressing rod 52, the label pressing portion 56 absorbs the impact due to the downward movement of the pressing rod 52, and the label pressing portion 56 moves. The downward movement does not press and crush the adherend A.

In this embodiment, three pressing devices 50 are formed side by side, as shown in FIG.
Each of them is configured such that the pressing rod 52 descends independently. Therefore, even if an uneven surface is formed on the surface of the adherend A or a step is formed, the pressing rod 52 of each pressing device 50 accurately reaches the surface of the adherend A and the label 28 is densely packed. Can be attached to the surface of the adherend A.

The present invention is not limited to what has been described above, and for example, the display of the label 28 may be formed by a thermal printing device, or may be formed by an ordinary ink printing device.

According to the label pressing portion 56 of this embodiment,
In the direction of the vertical axis 100a of the tubular body 100,
Since the label 28 is configured to be attached to the adherend A as the pressing rod 52 moves up and down along the axis 100a, the label is accurately and beautifully formed by the tubular body 100 that is relatively soft and has a waist. Can be attached to the adherend A.

Since the above-described embodiment is configured as described above, even if the size of the adherend A changes, the label 2 can be changed without changing the pressing device 50.
8 can be accurately pressed on the surface of the adherend A so that the label 28 can be neatly adhered to the adherend A, and the plurality of pressing devices 50 are configured to operate independently. Therefore, even if the surface of the adherend A has unevenness or a step surface is formed, the pressing rod 52 of the independent pressing device 50 corresponds to the height of the surface of the adherend A.
Will reach the surface of the adherend A, respectively, and the label 28 can be accurately and beautifully adhered to the adherend A.
