(b) It is displaced in the direction D 'together with the displacement support member 40 including the peeler 30, so that the position at which the second label 14 is attached can be changed. As described above, by operating the displaceable means, the first label 120 and the second label 14 are attached and laminated at correct positions.

Next, a device for attaching the first label 120 will be described. The first label 120 affixing device 110 includes a holding reel 114 rotatably provided on the base 12 as a holding means. The holding reel 114 includes a label continuous body.
116 is held in a roll.

5A and 5B, the label continuum 116 includes a strip-shaped release liner 118 serving as a first support liner, and the release liner 118 is spaced apart in the longitudinal direction thereof. One label 120 is temporarily attached by an adhesive layer 120a on the back surface. The release liner 118 includes, for example, a band-shaped sheet material such as paper or synthetic resin, and a release agent layer is formed by applying a release agent such as silicon on the surface of the sheet material. Therefore,
The first label 120 is temporarily and releasably attached to the peeling mount 118.

One end of the label continuum 116 is unraveled from the holding reel 114 and guided to the label detector 126 via the guide rollers 122 and 124. In this case, the guide roller 122 is supported by an arm 122a for applying a back tension to the label continuous body 116. Thus, the label continuum 116 is given back tension from the arm 122a and does not sag.

The label detector 126 is for detecting the leading end of the first label 120 and includes a photoelectric switch and is connected to a control unit (not shown). When the label detector 126 detects the leading end of the first label 120, the control unit sends the first label.
A signal for temporarily stopping the label 120 (peeling backing sheet 118) is given.

The label continuum 116 is guided via guide rollers 128 and 130 between a platen roller 132 and a thermal head 134 which constitute a part of the printing unit.

Further, the thermal ribbon 136 is guided between the platen roller 132 and the thermal head 134 such that the thermal ribbon 136 is stacked on the label continuous body 116. As shown in FIG. 6, the thermal ribbon 136 includes a band-shaped sheet material 136a, and a thermal transfer layer 136b is formed on the surface of the sheet material 136a. Then, as shown in FIG. 7 in particular, the thermal ribbon 136 passes through
36b is guided between the platen roller 132 and the thermal head 134 such that the surface 36b faces the surface of the first label 120 of the label continuous body 116. Therefore, thermal head 1
By heat-transferring the thermal transfer layer 136b of the thermal ribbon 136 to the surface of the first label 120 at 34, the print layer 120b can be formed on the surface of the first label 120.

The thermal ribbon 136 is held on a holding reel 138 in a state of being wound in a roll shape. One end of the thermal ribbon 136 passes through a guide roller 130, a platen roller 132, and a thermal head 134, and then is wound in a roll shape on a take-up reel 137. Taken.

Thus, the first label 12 on which the printing layer 120a is formed
0 (label continuum 116) is used for guide rollers 150, 152 and 1
Guided to 54 in order. The guide roller 152 is a guide roller 1
It is provided so as to be vertically displaceable at substantially the center of 50 and 154.

That is, the guide roller 152 is supported by the support member 156 as shown in FIG. This support member 156
Are formed with holes 156a and 156b penetrating vertically on both sides thereof, and guide holes are formed in these holes 156a and 156b.
158a and 158b are inserted. Therefore, the support member 156 is vertically displaceable. The upper and lower ends of the guide columns 158a and 158b are fixed to fixing members 160a and 160b fixed to the base 12, respectively. In the center of the support member 156, a female screw portion 156c penetrating vertically is formed. This support member 156
A lead screw or a ball screw 162 is screwed into the female screw portion 156c. Between the upper and lower sides of the ball screw 162, the fixing member 1
It is rotatably supported by 60a and 160b, respectively. Further, the knob 164 is provided with a ball screw 162 above the fixing member 160a.
Is provided in a form connected to the upper end of the. Therefore, by rotating the knob 164 in the direction shown by the arrow A in FIG. 8, the support member 156 and the guide roller 152 are displaced in the direction shown by the arrow A 'in FIG. Conversely, by rotating the knob 164 in the direction shown by the arrow B in FIG. 8, the support member 156 and the guide roller 152 are displaced in the direction shown by the arrow B 'in FIG. 8, that is, downward.

Thus, by displacing the guide roller 152 in the vertical direction, the position of the first label 120 with respect to the thermal head 134 can be adjusted.

For example, as shown by the chain line in FIG. 9A, if the position of the first label 120 is on the upstream side in the transport direction with respect to the thermal head 134, the knob 164 is rotated in the arrow A direction in FIG. As shown by the solid line in FIG. 9A, the guide roller 152 may be displaced upward, and the first label 120 may be displaced downstream in the transport direction. Conversely, if the position of the first label 120 is on the downstream side in the transport direction with respect to the thermal head 134 as shown by the dashed line in FIG. 9B, the knob 164 is moved in the arrow B direction in FIG. By rotating, as shown by the solid line in FIG. 9B, the guide roller 152 may be displaced downward, and the first label 120 may be displaced upstream in the transport direction.

Therefore, by adjusting the knob 164, the first label 120 can be displaced to an accurate position with respect to the thermal head 134.

Then, the first label 120 on which the print layer has been formed in the thermal head 134 is sent between the joining rollers 170a and 170b with the transfer of the release liner 118. The second labels 14 are stacked by the joining rollers 170a and 170b.

Subsequently, the transfer means of the label continuum 116 of the first label 120 will be described.

The label continuum 116 is guided between the joining rollers 170a and 170b, and the second labels 14 peeled off from the backing sheet 20 by the peeling device 30 by the action of the joining rollers 170a and 170b. Label 120 is joined,
By the function of the adhesive layer 14a on the back surface of the second label 14,
The second label 14 is superimposed on the surface of the first label 120, and both are adhered.

Feeding drive is applied to the joining roller 170b, and the other joining roller 170a is provided on the base 12 so as to be able to be separated from the joining roller 170b. Therefore, the label continuum 11
6 can be easily loaded.

Then, by the operation of the joining rollers 170a and 170b, the second label 14 is fed to the next first label peeler 180 provided in a state where the second label 14 is laminated on the surface of the first label 120. Then, by the first label peeler 180, the peeling backing sheet 118 constituting the label continuous body 116
The first label 120 in a state where the second label 14 is stacked
Is peeled from the peeling backing sheet 118, and the first label peeler 1
The label is sucked by a vacuum suction device provided in the vicinity of the tip of 80, and the label is sent to a vacuum sticking device 190 which sprays the label with a blower and sticks the label on an adherend.

On the other hand, the peeling mount 118 after the first label 120 is peeled off by the first label peeling device 180 is transferred in a direction substantially opposite to the traveling direction of the first label 120, and the base 1
The sheet is wound around a first take-up reel 186 by the action of a feed roller 184 that feeds a peeling backing sheet 118 via a guide roller 182 rotatably provided in 2.

A nip roller 188 is formed so as to face the feed roller 184, and the feed of the release liner 118 is ensured. The nip roller 188 is detachable from the feed roller 184,
To facilitate loading of the release liner 118.

Therefore, while the label continuum 116 pulled out from the holding reel 114 is being transferred, necessary printing is performed on the main surface of the first label 120 by the action of the thermal head 134, and the transferred label continuum 116 is further transferred. The second label 14 pulled out from the holding reel 16 is laminated on the main surface of the first label 120 by the action of the second label sticking device 10, and the first label peeler 180 removes the backing paper 118
Is peeled off from the first label 120. Then, the second label 14 was stacked on the surface of the adhered body, for example, the surface of a cardboard box, which was sent by a belt conveyor (not shown) provided below the vacuum applicator 190 by the action of the vacuum attaching device 190. The first label 120 in the state is adhered.

In this embodiment, the transfer printing is performed on the surface of the first label 120 with the thermal ribbon 136. However, as the first label 120, a thermosensitive coloring agent is applied to the surface of the first label 120. A thermosensitive coloring label having a coloring layer formed thereon may be selected, and the first label 120 may be thermosensitively colored by the action of the thermal head 134.
In addition, a printing device having another structure can be used.

Therefore, if a printing unit that does not use the thermal ribbon 136 is collected, a device that sends the thermal ribbon 136 to the surface of the first label 120, that is, the holding reel 138, the guide roller 130, the take-up reel 137, and the like become unnecessary.
