The present invention relates to a mountless label separating apparatus and a mountless label separating method of a portable mountless label sticking machine.

2. Description of the Related Art Conventionally, a label is attached to various products and other objects to be attached using a portable label applicator, and the price of the product and other necessary information are displayed.
When using this portable label applicator, in a state where the label is rolled up, it is loaded and held in a holder such as a paper holder in the portable label applicator, and the label is fed out from the paper holder into a belt shape. It must be inserted into a portable label applicator and loaded in a state where it can be transferred or printed.

As a label to be loaded into the portable label applicator, it has a strip-shaped label base material, an adhesive layer provided on the back surface of the label base material, and a release agent layer provided on the surface of the label base material, There is a non-mounting label without a mount, and the non-mounting label can contribute to resource saving because it does not have a mount.
In the portable no-board label sticking machine used by loading the label without the mount, a mechanism for pressing the press member against the transfer roller portion and engaging the label without the mount to be loaded and transferred in the machine, and further, the transfer roller There is a need for a mechanism to move the label without a mount from the transfer roller to the next (eg, downstream endless belt for transfer) by reliably separating the label without the mount.

    However, in the conventional portable mountless label applicator, the number of parts of the separation mechanism between the mountless label and the transfer roller is large, and the structure of the separation mechanism itself is complicated. There is a problem that the maintenance operation itself takes time.

    Furthermore, when the gripping and operating levers are gripped and released, and the transfer roller is driven to rotate at a predetermined pitch to transfer the label without the mount, the reverse rotation of the transfer roller is prevented by this gripping and releasing operation. However, a mechanism for stably transporting the label without a mount in one direction is also necessary.

    In addition, when pasting a label on which sales promotion information or advertisement information is printed in advance, the label can be pasted only by operating the operation lever without providing a printing unit. Even in the case of a platen unit of a label mounter without a type mount, there is a similar problem in that it is necessary to separate the label without a mount from the transfer roller to ensure stable transfer.

    As described above, the transfer claw 38 of the transfer roller 18 can be engaged with and disengaged from the transfer slit 3 </ b> A of the label 3 without the mount, and the separation claw piece 53 of the separation claw element 49 is arranged on the outer circumference of the transfer roller 18. The portion of the groove 39 or the outer circumferential groove 39 and the backup roller 41 of the pressing element 19 can be faced, and the tip of the separating piece 53 is connected to the transfer claw 38 and the transfer roller. It can be positioned on the upstream side of the engagement portion with the slit 3A.

In the portable mountless label sticking machine 1 and the mountless label separating apparatus 9 configured as described above, the opening / closing knob 26 is operated, and the engagement between the engagement recess 28A of the opening / closing engagement / disengagement piece 28 and the engagement / disengagement roller 25 is performed. When the platen unit 6 is opened with respect to the side plate 2 by releasing the engagement, the torsion coil spring 43 receives the reaction force from the lever shaft 11 or the side plate 2 via the plate spring 44, and the torsion coil spring 43 moves from the pressing element 19 to the transfer roller 18. The portions are separated from each other, and a gap 45 is formed by maximally opening between the transfer roller 18 and the pressing element 19.
Accordingly, a portion of the gap 45 formed between the central circumferential groove 37, the transfer claw 38 and the outer circumferential groove 39 in the circumferential portion of the transfer roller 18, and the backup roller 41 and the backup ring 42 of the pressing element 19. The leading portion of the label 3 without the mount can be inserted.
Next, the platen unit 6 is closed to the state shown in FIG. 1, the engagement / disengagement recess 28 </ b> A of the opening / closing engagement / disengagement piece 28 is engaged with the engagement / disengagement roller 25, and the operation lever 5 and the grip 10 are gripped several times. Then, if the transfer claw 38 is engaged with the transfer slit 3A of the label 3 without mount, the transfer of the label 3 without mount is enabled and the loading is completed.

In the portable mountless label pasting machine 1 with the platen unit 6 closed, the printer 7 prints on the mountless label 3 on the transfer endless belt 23 by grasping the operation lever 5 and the grip 10. At the same time, the transfer rotation claw 32 moves from the transfer protrusion 33 of the roller gear 24 in the transfer roller 18 to the adjacent transfer protrusion 33 side (on the right side in FIG. 3). The moving claw 32 rotates the transfer protrusion 33 forward (to the left in FIG. 3), and the transfer roller 18 is rotated at a predetermined pitch to transfer the non-mounting label 3.
Further, the drive gear 21 engaged with the transfer roller 18 rotates to rotate the transfer endless belt 23 so that the non-mounting label 3 on the upper surface thereof can be fed out of the side plate 2.
The label piece 3B of the mountless label 3 fed to the outside of the side plate 2 at the leading end (downstream side) of the transfer endless belt 23 can be attached to a predetermined adherend by the attaching roller 8.

Note that the transfer rotation claw 32 is adjacent to the transfer protrusion 33 of the roller gear 24 in the transfer roller 18 (on the right side in FIG. 3) by gripping the operation lever 5 and the grip 10. 10, since the reverse rotation prevention piece 54 of the separation claw element 49 is engaged with the reverse rotation prevention recess 58 of the transfer roller 18 as shown in FIG. 10 in particular, the transfer roller 18 is shown in FIG. There is no rotation (reverse rotation) in the clockwise direction, so that stable transfer of the non-mounting label 3 by the transfer roller 18 is ensured.
Of course, when the transfer roller 18 rotates in the clockwise direction (transfer direction) by releasing the operation lever 5 and the grip 10, the reverse rotation prevention piece 54 moves to the next reverse rotation prevention recess 58 and engages.

Further, the pair of left and right separation claw pieces 53 of the separation claw element 49 are positioned between the pair of left and right outer circumferential grooves 39 in the transfer roller 18 and the label 3 without the mount by the label separation device 9 without mount. Therefore (the first attitude), the surface side of the mountless label 3 that has been transferred to the separation claw piece 53 by engaging with the transfer claw 38 of the transfer roller 18 is in contact with the bottom surface of the separation claw piece 53. However, as a result of the separation of the transfer slit 3A of the non-mounting label 3 from the transfer claw 38, the transfer claw 38 is forcibly separated from the transfer claw 38 and moves onto the transfer endless belt 23.
By the engagement rotation between the roller gear 24 of the transfer roller 18 and the drive gear 21 of the transfer endless belt 23, the non-mounting label 3 on the transfer endless belt 23 is further transferred toward the driven gear 22. Become.

    Further, maintenance is necessary for the operation such as jamming of the non-mounting label 3 between the transfer roller 18 and the endless belt 23 for transfer, or the removal and cleaning of the adhesion of glue to the parts and mechanisms around the same. In this case, as shown in FIGS. 7 and 8, the separation claw element 49 (the rotation arm 50) in the label separating apparatus 9 without mount is rotated and released so as to be pulled upward around the rotation projection 56, Retract from between the transfer roller 18 and the transfer endless belt 23 to the second posture, that is, the separation claw element 49 is simply released from its operating position, and the mountless label 3 around the transfer roller 18 The state can be confirmed, and necessary cleaning and other operations can be performed on the part to which the glue is attached.

Thus, with the label separator 9 having no simple configuration as described above, the transfer of the label 3 without the mount on the transfer roller 18 and the transfer to the endless belt 23 for transfer can be reliably performed. Internal maintenance can be performed easily.
