Next, the operation of the first embodiment will be described in detail with reference to FIG.
FIG. 4 is an explanatory diagram for explaining the operation of changing the injection direction of the auxiliary blowing nozzle in the embodiment of the label sticking device according to the present invention.

  When the print data transmitted from the host 2 is received, the CPU 42 analyzes the command of the received print data, reads out font data corresponding to the character information included in the print data from the ROM 41, and corresponds to the print data. Bitmap image data in which characters are expanded is expanded in the drawing area of the RAM 43.

  Next, the CPU 42 instructs the print control unit 44 to perform printing. The print control unit 44 supplies a control signal to the thermal head 13 corresponding to the bitmap image data developed in the drawing area of the RAM 43 based on an instruction from the CPU 42, and in response to an instruction from the CPU 42. Based on this, the platen roller 12 is rotationally driven to perform the printing process. As a result, the print data is printed on the label 3 while the platen roller 12 and the thermal head 13 sandwich and convey the label continuum 8, and the belt-like mount 7 is folded back at the tip of the release plate 14 on the label 3 on which the printing has been performed. As shown in FIG. 4 (a), it is peeled off from the belt-like mount 7 and issued.

  Next, the CPU 42 instructs the nozzle controller 47 to perform auxiliary blowing and also instructs the sticking controller 45 to suck and stick the issued label 3. As shown in FIG. 4A, the nozzle control unit 47 drives an air supply device (not shown) at the timing when the protruding length of the label 3 peeled from the belt-like mount 7 from the peeling plate 14 reaches a predetermined length L. The air injection from the auxiliary blow nozzle 30 is started to blow air on the back surface of the label 3 and the nozzle rotation motor 33 is rotated in the direction of arrow A to issue the air injection direction from the auxiliary blow nozzle 30. Follow the movement of the label 3. That is, by appropriately setting the predetermined length L, a location where the air jetted from the auxiliary blowing nozzle 30 is blown on the back surface of the label 3 is determined, and control is performed so that air is always blown near the location. As a result, the air jetted from the auxiliary blowing nozzle 30 is always blown to an appropriate position on the back surface of the issued label 3, and the issued label 3 is guided to the air blown from the auxiliary blowing nozzle 30. The process proceeds to the suction surface of the suction plate 21 and is supplied to the suction surface of the suction plate 21 as shown in FIG. The predetermined length L may be set in advance, may be set by input from the input unit 50, or may be set based on a pitch signal based on the detection signal from the label detection sensor 16, or from the host 2. You may make it set according to the size of the label 3 which can be discriminate | determined from the printing data etc. which were transmitted. In addition, when the RFID is built in the label 3, it is preferable to set the predetermined length L so that air is blown to the place where the RFID is built. Further, a predetermined length L for determining the timing of starting the air injection so that the portion where the air injected from the auxiliary blowing nozzle 30 is blown on the back surface of the label 3 is in the range from the tip of the label 3 to the middle. The rotation speed of the nozzle rotation motor 33 is preferably set.

  The sticking control unit 45 sucks the vacuum device connected to the suction plate 21 immediately after the issued label 3 is supplied to the suction surface of the suction plate 21, and sucks the label 3 on the suction plate 21, thereby predetermined At this timing, the cylinder 23 is driven to extend the rod 22, and the vacuum device connected to the suction plate 21 is sprayed to spray the label 3 toward the object 5 to be pasted.

  As described above, according to the first embodiment, the auxiliary blowing nozzle that blows air onto the back surface of the issued label 3 and guides the issued label 3 to the suction plate 21 by injecting air. 30 and the nozzle control unit 47 rotates the nozzle rotation motor 33 so that the air injection direction from the auxiliary blowing nozzle 30 is issued so that air is blown to substantially the same location on the back surface of the label 3. The leading edge of the label 3 is caused by following the movement of the label 3 and changing the location where the air is blown to move in the direction in which the label 3 is issued. Since the air can be blown in accordance with the movement of the issued label 3 even when the weight of the auxiliary label is increased, the auxiliary blowing nozzle 30 is provided at an appropriate position on the back surface of the issued label 3. Can blow et injected air, the issued label 3 to guide the correct position of the suction plate 21, an effect that can be firmly adsorbed labels 3 to the adsorption plate 21.

(Second Embodiment)
FIG. 5 is an explanatory diagram for explaining the operation of setting the injection direction of the auxiliary blowing nozzle in the second embodiment of the label sticking device according to the present invention.

  In the second embodiment, the injection direction of the air from the auxiliary blowing nozzle 30 is set according to the size of the label 3 to be issued, and the injection direction of the air from the auxiliary blowing nozzle 30 is set and issued. This is different from the first embodiment in that air is blown and guided to the back surface of the label 3. That is, the CPU 42 determines the size of the label 3 to be issued based on the pitch signal based on the detection signal from the label detection sensor 16 and the print data transmitted from the host 2, and before issuing the label 3, The determined size is notified to the nozzle controller 47.

  When notified of the size of the label 3, the nozzle control unit 47 rotates the nozzle rotation motor 33 and sets the jet direction of the air from the auxiliary blowing nozzle 30 according to the size of the label 3. FIG. 5 (a) shows the injection direction set according to the small size label 3, and FIG. 5 (b) shows the injection direction set according to the large size label 3. The smaller the size of the label 3 is, the more air is blown to the portion closer to the tip of the peeling plate 14, and the larger the size of the label 3 is, the more air is blown to the portion far from the leading end of the peeling plate 14. In addition, the air injection direction from the auxiliary blowing nozzle 30 is set.

  Further, when the nozzle 42 is instructed to perform auxiliary blowing from the CPU 42, in the case of the small-sized label 3, as shown in FIG. 5A, the peeling plate of the label 3 peeled from the belt-like mount 7. In the case of the large-sized label 3 at the timing when the protruding length from 14 reaches the predetermined length M, as shown in FIG. 5B, the label 3 peeled off from the strip-shaped mount 7 from the peeling plate 14 At a timing when the protrusion length reaches a predetermined length N greater than the predetermined length M, an air supply device (not shown) is driven to start air injection from the auxiliary blowing nozzle 30 to blow air onto the back surface of the label 3. As described above, the timing of air injection may be controlled according to the size of the label 3.

  After the air injection is started, air may be blown in the same injection direction without changing the air injection direction. However, as in the first embodiment, the nozzle rotation motor 33 is moved to the arrow. It is more effective to rotate in the A direction and follow the movement of the label 3 to be issued in the air injection direction from the auxiliary blowing nozzle 30.

  As described above, according to the second embodiment, the auxiliary blowing nozzle that blows air onto the back surface of the issued label 3 and guides the issued label 3 to the suction plate 21 by injecting air. 30, the CPU 42 determines the size of the label 3, and the nozzle control unit 47 sets the air injection direction from the auxiliary blowing nozzle 30 according to the size of the label 3 determined by the CPU 42. By configuring, even if the size of the label 3 is changed, the air jetted from the auxiliary blowing nozzle 30 can be blown to an appropriate place on the back surface of the issued label 3, and the issued label 3 is adsorbed. The effect is that the label 3 can be firmly adsorbed to the adsorbing plate 21 by being guided to an accurate position of the plate 21.
