Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printing and cutting apparatus for a label without a mount, and in particular, so that printing, cutting and transfer of a continuous mountless label having an adhesive layer on the back surface of a strip-shaped label substrate can be performed smoothly. The present invention relates to a printing and cutting device for a label without a mount.
[0002]
[Prior art]
As a conventional label continuous body, a label continuous body 1 with a mount as shown in FIG. 4 is generally used.
The label continuous body 1 with mount includes a strip-shaped mount 2 and a large number of label pieces 3.
[0003]
A release agent layer 4 made of silicon oil or the like is provided on the surface of the mount 2, and an adhesive layer 5 is provided on the back surface of the label piece 3. The label piece 3 is temporarily attached to the surface of the mount 2 so as to be peeled off. is there.
[0004]
In general, as shown in the figure, the label continuous body 1 with mount is wound and handled in a roll shape. However, since the mount 2 is on the back surface of the label piece 3 (adhesive layer 5), it may be wound in a roll shape. The label pieces 3 can be processed without sticking to the pressure-sensitive adhesive layer 5, and after the predetermined print information is printed on the label pieces 3, they can be peeled off from the mount 2 and attached to a predetermined product.
[0005]
However, the mount 2 is irrelevant and unnecessary with respect to the original information display function of the label continuous body 1 with mount, and is a completely useless component in terms of cost.
[0006]
Therefore, a mountless label 6 as shown in FIG. 5 has been developed.
The mountless label 6 has a strip-shaped label base material 7 corresponding to a large number of label pieces 3, and is provided with an adhesive layer 5 on the back surface of the label base material 7, and a thermosensitive color former on the surface of the label base material 7. The release agent layer 4 made of silicon oil or the like is provided on the layer 8 and further on the heat-sensitive color former layer 8. In addition, the heat-sensitive color former layer 8 can be omitted and the release agent layer 4 can be directly provided on the label substrate 7.
[0007]
Even if the label 6 having no mount is wound in a roll shape as shown in the drawing, the adhesive layer 5 on the back surface side contacts the release agent layer 4 on the front surface side, so that the label base materials 7 are adhered to each other. There is no end.
[0008]
A label piece corresponding to the label piece 3 is formed by making the thermosensitive color former layer 8 develop a color with a predetermined printing pattern by using a thermal printer or the like and printing the predetermined information on the label 6 without the mount and cutting it at a predetermined pitch. 3A can be obtained.
[0009]
FIG. 6 is a side view schematically showing a thermal printer 9 that performs this printing cutting operation. The thermal printer 9 is provided with a printing mechanism 10 and a cutting mechanism 11 along the transfer direction.
[0010]
In the printing mechanism 10, the non-mounting label 6 is passed between the platen 12 subjected to silicon processing or the like and the thermal head 13, and along with the transfer of the non-mounting label 6 in the forward direction by the rotation of the platen 12, Printing is performed by supplying a predetermined printing signal.
[0011]
Further, the label 6 having no mount after printing is supplied between the fixed blade 14 (cutter lower blade) and the rotary blade 15 (cutter upper blade) in the cutting mechanism 11. Is cut to obtain a single-leaf label piece 3A having a predetermined length.
[0012]
However, when the cutting mechanism 11 is used to cut the non-mounting label 6, the adhesive layer 5 is attached to the fixed blade 14 located on the back side of the non-mounting label 6 so that the tip 6A of the non-mounting label 6 is fixed. 14 will stick.
[0013]
Therefore, as shown in FIG. 7, in the state where the label 6 without mount is adhered to the cutting mechanism 11 (fixed blade 14) by the adhesive layer 5, there is no mount for printing on the next label 6 without mount. When the label 6 is transferred, the label 6 having no mount is bent between the printing mechanism 10 (platen 12) and the cutting mechanism 11 (fixed blade 14), and the label 6 is transferred beyond the cutting mechanism 11. There is a problem that it becomes impossible to wind around the platen 12.
[0014]
Such a problem occurs when the label 6 without a mount is cut even by other cutting mechanisms such as a structure in which the cutting blade moves linearly in addition to the cutting mechanism 11 having the fixed blade 14 and the rotary blade 15. Is.
[0015]
[Problems to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION
Next, a print cutting apparatus 20 for a label without a mount according to an embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 4 to 7 are denoted by the same reference numerals, and detailed description thereof will be omitted.
FIG. 1 is a side view of a main part of a printing / cutting device 20 for a label without a mount, which includes the printing mechanism 10, a guide mechanism 21, the cutting mechanism 11, and a label drawer. A mechanism 22 and a control mechanism 23 are included.
[0026]
The printing mechanism 10 includes the platen 12, the thermal head 13, a platen drive motor 24 that can rotate the platen 12 in the forward direction (the transfer direction of the non-mounting label 6) and the reverse direction, and a timing belt 25. .
[0027]
The guide mechanism 21 includes a guide roller 26 provided at the tip of the thermal head 13 and a guide piece 27.
The mountless label 6 is passed through the gap between the guide roller 26 and the guide piece 27 so as to be surely guided to the cutting mechanism 11 on the downstream side.
[0028]
The front end 6A of the label 6 without mount, which has been cut by the cutting mechanism 11, is pulled away from the cutting mechanism 11 in the direction opposite to the transfer direction, and then the transfer is resumed in the transfer direction along with the printing operation. As the guide mechanism 21 for reliably guiding the tip 6A sometimes, only the guide piece 27 positioned below the contact point between the platen 12 and the thermal head 13 at a predetermined interval may be used.
[0029]
The cutting mechanism 11 includes the fixed blade 14 and the rotary blade 15, a cutter drive motor 28 that rotationally drives the rotary blade 15 in one direction, and a timing belt 29.
The rotary blade 15 stands by at a position that does not hinder the transfer of the label 6 without label or the label piece 3A after one rotation for cutting.
[0030]
The label drawing mechanism 22 includes a drawing roller 30 that has been subjected to silicon processing, a pressing roller 31, a roller drive motor 32 that rotationally drives the drawing roller 30 in one direction, and a round belt 33.
The label drawing mechanism 22 is for transferring a single-leaf label piece 3A formed by cutting further downstream than the cutting mechanism 11.
[0031]
The control mechanism 23 receives signals from the upstream side detection sensor 34 and the downstream side detection sensor 35 and a print information signal from an external control mechanism (for example, the personal computer 36), as well as the above-described mechanisms, the print mechanism 10, and the cutting mechanism. 11 and the label drawing mechanism 22 are controlled.
[0032]
The upstream detection sensor 34 detects the presence or absence of the non-mounting label 6 when detecting the pitch by detecting a detection mark (not shown) of the non-mounting label 6 or in a configuration in which the pitch is determined by the amount of print data. It may be detected.
[0033]
The downstream detection sensor 35 detects the presence or absence of the label piece 3 </ b> A by the label drawing mechanism 22.
[0034]
In the print cutting apparatus 20 for a label without a mount having such a configuration, the timing for performing a reverse transfer operation (back feed operation) for separating the leading end 6A of the label 6 without a mount 6 cut by the cutting mechanism 11 from the fixed blade 14 is as follows. For example, it may be started by a print start signal from the control mechanism 23 or may be started by a print end signal.
[0035]
FIG. 2 is a flowchart showing the print cutting operation when the back feed operation is started by the print start signal from the control mechanism 23. In step S1, the initial printing is performed in step S1 by turning on the power of the print cutting apparatus 20 for the non-mounting label. Do the set.
That is, the leading portion of the non-mounting label 6 that is initially loaded in the printing / cutting device 20 for the non-mounting label is located on the downstream side of the cutting mechanism 11, and the rotary blade 15 is rotated once by the cutter driving motor 28. As a result, the leading portion of the label 6 having no mount is cut and the leading end 6A is aligned.
[0036]
In step S2, print data is received from the personal computer 36 (external control mechanism). When print editing is completed in step S3, a print start signal is output and backfeed in step S4 is performed.
[0037]
The back feed, by rotating the platen 12 of the printing mechanism 10 in a direction opposite to the transport direction, between the tip without mount label and the guide rollers and the guide piece, the peek position, the platform paper unlabeled 6 The tip 6A is pulled back to the upstream side and is pulled away from the fixed blade 14 of the cutting mechanism 11. For example, the tip 6A is allowed to pass between the platen 12 of the printing mechanism 10 and the thermal head 13, or it is allowed to pass into the gap between the guide roller 26 and the guide piece 27 of the guide mechanism 21. Keep away from.
[0038]
Next, in step S5, printing by the printing mechanism 10 is started, and in step S6, the drawing roller 30 of the label drawing mechanism 22 is rotated, and the label 6 (label piece 3A) that has been cut last time is pulled out, and predetermined processing is performed. .
As this process, a process of adhering to a predetermined product by adsorbing with a label adsorber (not shown), a process of applying with an application roller (not shown), or a manual application process, or a stacker (not shown). ) And the like.
[0039]
In step S7, it is confirmed whether or not the printing on one label piece 3A has been completed. In step S8, the cutting mechanism 11 is operated to set the label 6 without mount to the label piece 3A having a predetermined pitch.
[0040]
By this cutting operation, the tip 6A of the label 6 without mount is stuck to the fixed blade 14. However, during the printing operation to the next label 6 without mount, it is separated from the fixed blade 14 by backfeeding. It is pulled back to the proper position.
[0041]
At the time of resuming the transfer of the label 6 without mount accompanying the next printing operation, the front end portion 6A is guided by the guide mechanism 21 (particularly, the guide piece 27) and supplied to the cutting mechanism 11 through a predetermined transfer path. be able to.
[0042]
According to the print cutting operation according to the flowchart of FIG. 2, back feed is performed in accordance with the print start signal output from the control mechanism 23 after confirming the completion of print editing in step S <b> 3. Backfeed will be performed after some time from the operation.
[0043]
FIG. 3 is a flowchart showing the print cutting operation when the back feed operation is started by the print end signal from the control mechanism 23. The initial setting in step S11, the data reception in step S12, and the print editing in step S13 are completed. The confirmation and the like are the same as those in the flowchart shown in FIG.
[0044]
Next, printing is started in step S14, the drawing roller 30 is rotated (step S15), the completion of printing is confirmed (step S16), the cutting mechanism 11 is driven in step S17, and in response to the output of the printing end signal. In step S18, back feed is performed.
[0045]
According to the print cutting operation according to the flowchart of FIG. 3, back feed is performed following the cutter operation in step S <b> 17 in accordance with the print end signal output from the control mechanism 23 after confirming the print end in step S <b> 16. The back feed is performed immediately after cutting the non-mounting label 6.
[0046]
Thus, it is avoided that the next printing operation by the printing mechanism 10 is started while the front end portion 6A of the label 6 without mount is stuck to the fixed blade 14 of the cutting mechanism 11, and the label without mount is not required. The printing cutting operation utilizing the advantages of 6 can be performed.
