BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label-less label sticking apparatus, and more particularly to a label-less label sticking apparatus for sticking a label without a label having predetermined display information to an article to be stuck.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a label sticking device that sticks a label having product information or other predetermined display information to a product or other article to be pasted. An adhesive layer is formed on the back side of the label so that it can be attached.
The display information may be printed in the case where the label has been printed in advance, or may be printed in the process of transporting the label into a predetermined transport path. However, in any case, it is necessary to transport the label, and when separating adjacent labels. It is necessary to eliminate the problems caused by the pressure-sensitive adhesive in the transfer path, such as being difficult to separate from each other or adhesion between the label and another mechanism portion.
[0003]
In particular, at the final stage of label application, there is a possibility that when adhering the label to the suction disk, it may not be possible to shift to the application operation due to sticking with an adhesive on the upstream label or other mechanism part, or Even if a label is affixed to an article to be affixed, the label affixing operation itself may be hindered, such as the possibility that it cannot be affixed in a normal posture.
[0004]
Further, for a label without a mount different from a general label having a mount with a release agent layer, it is necessary to take measures for the adhesive layer over the entire transfer path from the supply to the pasting.
[0005]
FIG. 3 is a perspective view of the non-mounting label L. The non-mounting label L has a strip-shaped label base material L1 made of a paper material, and an adhesive layer L2 is provided on the back surface of the label base material L1. The heat-sensitive color former layer L3 is provided on the surface of the label substrate L1, and the release agent layer L4 made of silicon oil or the like is provided on the heat-sensitive color former layer L3. It is also possible to omit the heat-sensitive color former layer L3 and provide the release agent layer L4 directly on the label substrate L1.
[0006]
Even if the non-mounting label L having such a configuration is rolled up as shown in the figure, the adhesive layer L2 on the back side is in contact with the release agent layer L4 on the front side, so that the label base materials L1 are attached to each other. There is no end.
[0007]
A single-leaf label piece LA can be obtained by making the thermosensitive color former layer L3 develop a color with a predetermined printing pattern by using a thermal printer or the like to print the predetermined information by printing this predetermined label L and cutting it at a predetermined pitch. it can.

[Means for Solving the Problems]
That is, the present invention pays attention to slightly separating the label without a mount adsorbed on the suction disk to the downstream side, and adsorbs a single leaf label of a label without a mount having an adhesive layer on the back surface of the label base material. A non- mounting label sticking device having a board and a label sticking mechanism for sticking the label piece held by the suction board to an article to be pasted. A roller opposite to the direction is attached to the upstream end of the suction plate, a label pulling mechanism for pulling out the label piece from a predetermined transfer path and transferring it to the suction plate, and the suction plate with the label pullout and labels detached mechanism to further slightly moved to the downstream side of the mechanism, a sticking apparatus without mount label and having a.
[0014]
The label separating mechanism moves the suction plate to the downstream side by an interval corresponding to at least the radius of the roller in the sticking direction of the pair of rollers, so that the label without a mount is placed on the roller in the sticking direction. A label without a mount can be attached in a reliable and correct posture without causing a collision.
[0015]
The roller on the side opposite to the affixing direction functions as a pressing roller for the label without a mount in the affixing operation, so that the edge on the most upstream side of the label without a mount that is not completely in contact with the bottom surface of the suction disk Can also be pressed and pasted completely. Even when spraying with air pressure, the posture of the label without a mount can be stably maintained.
[0016]
As the pair of rollers, for example, a driving roller in the direction of applying the label without a mount and a driven roller on the opposite side of the attaching direction can be adopted. However, a configuration opposite to this may be adopted. The relative positional relationship of the rollers is arbitrary.
[0017]
As the label sticking mechanism, a structure in which the adsorbed non-mounting label is blown off by air pressure on an article to be stuck in the sticking direction, a structure in which the label without mount is moved in the sticking direction while being sucked and pressed directly on the sticking article, or no backing is provided There are various types such as a structure in which the label is moved in the sticking direction while adsorbed and then blown away in the direction of the article to be pasted by air pressure, and the sticking operation is performed by changing the direction of the suction plate in the sticking direction. is there.
[0018]
In the pasteless label pasting apparatus according to the present invention, the suction disk that sucks the label without the mount is slightly moved to the downstream side by the label separating mechanism. It can be separated from other non-mounting labels or other mechanism parts), and in the pasting direction with the adhesive remaining on the non-mounting label or other mechanism parts adjacent to the non-mounting label upstream. Without sticking operation, it is possible to reliably attach a label without a mount in a normal posture.
[0019]
Also, a pair of rollers to the label pull-out mechanism for transferring Pull None mount label being transported through the predetermined transport path, the opposite side of the rollers to the sticking direction of the pair of rollers (e.g., a driven roller) Since it is attached to the upstream end of the suction disk, it is possible to smoothly transfer the label without a mount from the label drawing mechanism to the suction disk.
[0020]
In addition, when adhering a label without a mount to the adsorber and pasting a label without a mount in the direction of application, the surface of the label without the mount (the side opposite to the adhesive layer) can be pressed, ensuring reliable application The operation can be performed. Of course, even when the label without a mount is blown off by air pressure, the surface of the label without a mount is supported by the roller, and a stable sticking operation can be expected.

DETAILED DESCRIPTION OF THE INVENTION
Next, taking as an example the case where the apparatus for pasting a label without a mount according to an embodiment of the present invention is installed in a thermal printer with a pasting mechanism for performing printing, cutting and pasting on the label without a mount, FIG. 1 and FIG. Based on the explanation.
FIG. 1 is an overall schematic view of the thermal printer 1 with an affixing mechanism. The thermal printer 1 with an affixing mechanism includes an apparatus frame 2, a supply shaft 3 for a label L without a mount, and a transfer path 4. The printing mechanism 5 for transferring the label L without mount and printing predetermined printing information, the cutter unit 6, the drawing device 7 for the cutter unit, and the label piece LA that has been cut into a single leaf state is pulled out from the cutter unit 6. A label drawing mechanism 8 and a non-mounting label sticking device 9 according to the present invention for sticking the drawn label piece LA to a predetermined article to be stuck (not shown).
[0022]
The transfer path 4 passes from the supply shaft 3 of the label L without mount paper, through the guide roller group 10 subjected to Teflon processing, to the printing mechanism 5, the cutter unit 6, the cutter unit drawing device 7, the label drawing mechanism 8, and the mountless paper. The label affixing device 9 is reached.
[0023]
In the printing mechanism 5, a label L without mount is passed between the platen 11 subjected to silicon processing or the like and the thermal head 12, and along with the transfer of the label L without mount in the forward direction by the rotation of the platen 11, the thermal head 12. Printing is performed by supplying a predetermined print signal to the.
[0024]
The cutter unit 6 includes a unit frame 13 and a cutter mechanism 14.
The cutter mechanism 14 has a fixed blade 15 (cutter lower blade) and a rotary blade 16 (cutter upper blade), and supplies the non-mounting label L to the transfer path 4 between them, and makes one rotation of the rotary blade 16. By cutting the label L without mount, a single-leaf label piece LA having a predetermined length is obtained.
[0025]
A guide piece 17 for the label L without mount is provided on the upstream side of the cutter mechanism 14.
In other words, by removing the label L without backing paper cut by the cutter mechanism 14 in the direction opposite to the transfer direction (by rotating the platen 11 in the reverse direction), the label L without backing paper and the cutter mechanism 14 can be separated. The guide piece 17 can be guided between the fixed blade 15 and the rotary blade 16 of the cutter mechanism 14 when the paper L is transported in the forward direction again.
[0026]
The cutter unit drawing device 7 moves the cutter unit 6 from the first position (storage position, cutting position) to the second position (drawing position, cleaning position) (on the front side of the sheet), and the cutter mechanism 14 And the surrounding area can be cleaned.
[0027]
The label drawing mechanism 8 has a drawing roller 18 (driving roller) and a pressing roller 19 (driven roller) that have been subjected to silicon processing, and a single-leaf label piece LA formed by cutting is further provided on a downstream side without a mount. To the pasting device 9.
[0028]
A label-less label sticking device 9 according to the present invention is attached to the device frame 2 of the thermal printer 1 with a sticking mechanism, and adsorbs the label pulling mechanism 8 and the label piece LA drawn by the label pulling mechanism 8. The adsorber 20, the label separating mechanism 21 that slightly moves the adsorber 20 further downstream than the label pull-out mechanism 8, and the adsorber 20 with the label pieces LA adsorbed in the attaching direction (downward in the figure). An air cylinder 22 (labeling mechanism) to be moved.
[0029]
FIG. 2 is a side view of the suction disk 20 and the label separating mechanism 21. In the labeling device 9 without a mount, the separating cylinder 24 attached to the cylinder rod 23 of the air cylinder 22 and the separating cylinder 24 are separated. A suction cup holder 26 that can reciprocate upstream and downstream (left and right in the figure) with respect to the separation cylinder 24 via a piston rod 25 of the separation cylinder 24, and the separation cylinder 24 and suction cup holder 26, and a return spring 27 provided between the two.
The suction cup 20 is attached to the bottom of the suction cup holder 26 via a cushion spring 28.
[0030]
The separation cylinder 24 is fixed to the piston rod 25 and the piston rod 25 in the right direction (upstream side) in the figure against the urging force of the return spring 27 by supplying compressed air from the air supply port 29. A certain suction cup holder 26 can be moved.
When the supply of compressed air to the separating cylinder 24 is released, the urging force of the return spring 27 returns the piston rod 25 and the suction cup holder 26 to the left (downstream side) in the figure.
[0031]
A number of suction holes 30 are opened on the bottom surface of the suction board 20 so that the label pieces LA transferred by the label drawing mechanism 8 can be sucked by a negative pressure.
[0032]
The pressing roller 19 is rotatably attached to the upstream end portion of the suction disk 20 by a rotary shaft arm 31.
The lower tangent direction of the pressing roller and the bottom surface of the suction disk 20 are located on the same plane.
[0033]
As shown in the drawing, the pressing roller 19 is engaged with the drawing roller 18 in a state where the suction disk holder 26 is moved to the upstream side, the label piece LA is sandwiched therebetween, and the drawing roller 18 by a drive motor (not shown). The label piece LA can be pulled out to the downstream side by the rotation of.
[0034]
In addition, after the label piece LA is adsorbed to the bottom surface of the suction disk 20, the suction disk holder 20 is moved horizontally to the downstream side in a state where the suction disk holder 26 is moved to the downstream side, and the label piece LA is completely removed from the label drawing mechanism 8. Can be pulled apart.
[0035]
The separation distance is sufficient if it is at least the radius R of the drawing roller 18 on the sticking direction side.
[0036]
In the labeling device 9 without a mount in such a configuration, the pressing roller 19 is engaged with the drawing roller 18 by moving the suction disk holder 26 to the upstream side by supplying compressed air to the separating cylinder 24. Then, the label L without the mount is cut into the label piece LA by the cutter mechanism 14 (FIG. 1) of the cutter unit 6 and is sandwiched between the drawing roller 18 and the pressing roller 19 of the label drawing mechanism 8, and the label piece is driven by the driving of the drawing roller 18. LA is supplied to the bottom surface of the suction disk 20.
[0037]
If the supply of compressed air to the separating cylinder 24 is released while the last LAB of the label piece LA reaches the label drawing mechanism 8 and is between the drawing roller 18 and the pressing roller 19, the return spring 27 Since the suction disk holder 26 and the suction disk 20 slightly move downstream, the rearmost LAB of the label piece LA can be reliably pulled away from the label drawing mechanism 8 (particularly, the drawing roller 18).
[0038]
Since the label L without the mount does not have a mount to be laminated with the label L, the transfer needs to be performed by directly contacting the label without the mount itself, and this is transferred by the label pulling mechanism 8 to the end. However, as described above, the label pulling mechanism 21 can ensure the pulling from the label pulling mechanism 8.
[0039]
Thus, a sticking operation to a predetermined product or other article (not shown) can be performed in a predetermined sticking direction (for example, downward in the figure).
[0040]
In this sticking operation, since the pressing roller 19 is in contact with the rearmost LAB of the label piece LA, it can function as a pressing roller, and the entire label piece LA can be reliably stuck.
[0041]
【The invention's effect】
As described above, according to the present invention, since the single-leaf label piece of the label without a mount is sucked by the suction disk and slightly moved downstream, the interference between the label piece and other mechanism portions is avoided. In addition, it is possible to prevent troubles caused by the pressure-sensitive adhesive layer and to ensure a reliable sticking operation.
[0042]
In particular, if a roller located on the opposite side of the sticking direction, such as a press roller, is attached to the tip of the suction cup, it will assist in sticking while guaranteeing the transfer of the non-mounting label that needs to be transported to the end. Can do.
