BACKGROUND OF THE INVENTION
The present invention relates to a label removing apparatus for removing a label that has moved to a surface opposite to a surface on which a plurality of labels are temporarily attached to a mount.
[0002]
[Prior art]
FIG. 4 shows a conventional label sticking apparatus 40 in which a main body frame 2 is provided with a supply unit 4, a label detection unit 6, a printing unit 8, a pasting unit 10, and a mount winding unit 12.
The supply unit 4 has a supply shaft 5 and is rotatably loaded with a roll-shaped label continuous body 27 around which a label continuous body 26 described later is wound. The label detection unit 6 includes a transmission type label detection sensor, and detects the amount of transmission between the mount 22 portion of the label continuous body 26 to be transferred and the label L and the mount 22 portion, and the label detection unit 6 has the paste unit 10. The leading end of the label L is stopped at the leading end of the peeling plate 14. The label detection sensor may be a reflective sensor.
[0003]
The printing unit 8 includes a print head 15 and a platen roller 16 and performs desired printing on the label L.
The affixing unit 10 has a peeling plate 14 and an affixing roller 20, and the peeling plate 14 is formed with an acute angle at its tip and the transported label continuous body 26 is mounted on the mount 22 at the tip of the peeling plate 14. The label L is peeled off from the mount 22 by turning. The peeled label L is fed forward, and the upper surface of the label L is pressed by the sticking roller 20 to be stuck to the adherend P. The turned mount 22 is transported and wound around the winding shaft 13 of the mount winding unit 12.
The winding shaft 13 is provided with a driving source (not shown) that is a moving means, and the winding shaft 13 can be rotated by driving the driving source so that the label continuous body 26 can be wound.
[0004]
FIG. 5 is a side view of the roll-shaped label continuous body. A release agent 23 such as a silicone resin is applied to any one surface of the long mount 22, and a pressure-sensitive adhesive 24 is provided on this surface. A plurality of labels L die-cut into a predetermined shape are temporarily attached at predetermined intervals. Thus, the roll-shaped label continuous body 27 is obtained by rolling the continuous label body 26 in which a plurality of labels L are temporarily attached to the long mount 22 at predetermined intervals.
[0005]
On the other hand, the transport device 21 for transporting the adherend P peels off and attaches the label L to the adherend P placed and transported below the label sticking device 40 (in the direction of the arrow in FIG. 4) at a predetermined timing. The label L is affixed to a desired position on the body P.
The label sticking device 40 described above includes the guide rollers 18 and 19, the label detection unit 6, and the label continuous body 26 that are fed from the roll-shaped label continuous body 27 loaded on the supply shaft 5 toward the transfer path. It is transferred to the printing unit 8 and the pasting unit 10.
When the adherend P is conveyed, printing is performed by the print head 15 at a predetermined timing, and the label L is peeled off at the sticking portion 10, and the label is placed at a desired position on the adherend P by pressing the sticking roller 20. L is affixed.
[0006]
However, when the label continuous body 26 is manufactured in the label manufacturing process, the label L is die-cut. At this time, the pressure-sensitive adhesive 24 may protrude from the edge portion of the label L. In particular, when the pressure-sensitive adhesive 24 is applied thick or when a strong adhesive is applied to increase the adhesive strength, the pressure-sensitive adhesive 24 protrudes from the edge portion of the label L.
[0007]
Thus, the pressure-sensitive adhesive 24 that protrudes from the edge portion of the label L is pressed by the winding pressure when the label continuous body 26 is rolled, and the pressure-sensitive adhesive 24 protrudes and is pressure-sensitive. The pressure sensitive adhesive 24 is attached to the back side of the mount 22 with the adhesive 24 covering the upper surface. And when the label continuous body 26 is pulled out from the roll-shaped label continuous body 27, the protruding pressure-sensitive adhesive 24 may stick to the back surface of the mount 22, so the label L peels off and the back of the mount 22 The label L may shift and the transition label L1 may stick to the back surface of the mount 22. (See Figure 5)
[0008]
The transition label L1 attached to the back surface of the mount 22 is attached to the label detection unit 6 or the platen roller 16 disposed in the transfer path. When the transfer label L1 is attached to the label detection unit 6, the sensor unit is hidden by the attached transfer label L1, so that there is a problem that the label continuous body 26 cannot be transferred. Moreover, even if it was going to remove the transfer label L1 which adhered, it took time to remove the adhesive 24, and the work efficiency fell.
[0009]
In addition, when the transition label L1 is attached to the platen roller 16, there is a problem that printing is lost and printing failure occurs.
[0010]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described problems, and prevents adhesion of a label to a label detection unit or a platen roller disposed in a transfer path for transferring a label continuum, thereby preventing printing defects. Provided is a label removing device that improves the efficiency of label attaching work.
[0011]
[Means for Solving the Problems]
The present invention focuses on removing the label attached to the back side of the mount, and a roll-shaped label continuous body in which a continuous label body in which a plurality of labels are temporarily attached to a long mount is formed into a roll shape And a transfer means for transferring the label continuum from the roll-shaped label continuum toward the transfer path, opposite to the surface on which the label of the label continuum fed to the transfer path is temporarily attached. The label removing apparatus is characterized in that a removing brush for removing the label transferred to the surface is disposed and the removing brush is detachable.
[0012]
In the label removing apparatus, the removing plate for removing the temporarily attached label is brought into contact with the surface of the removing brush.
[0013]
Therefore, since the label stuck on the back side of the mount can be removed by moving from the mount to the removal brush, printing failure is prevented and the work of applying the label is not interrupted. improves. Moreover, since the removal brush is made detachable, the attached label can be easily removed and cleaned.
[0014]
