Description

  The present invention relates to a label printing and sticking device, and more particularly to a label printing and sticking device for a continuous substrateless label.

  2. Description of the Related Art Conventionally, a label printing and sticking device has been widely used in which a printing mechanism is provided so that a label is sequentially stuck to an object to be stuck being conveyed by a conveyance mechanism while printing on the label (for example, Patent Documents). 1).

On the other hand, in response to a recent demand for resource saving, a label continuum without a mount has been used.
The label continuous body without mount is printed on the front surface, and an adhesive layer is formed on the back surface. A fragile separation portion such as is formed.

  By the way, since the label printing and sticking device described in Patent Document 1 does not have a mechanism for separating a piece of label from the label continuous body, the label continuous body without a mount cannot be used as it is.

  On the other hand, there has also been proposed a label printing and sticking device that can use a continuous label without a mount (see, for example, Patent Documents 2 and 3), but a printing mechanism at the time of label printing, label separation, and label sticking. In addition, the adjustment of the transfer speed of the label continuum and the label separated from the label continuity by the label affixing mechanism is not sufficiently taken (for example, refer to Patent Document 2), and complicated adjustment such as a torque limiter is required for the adjustment. Therefore, there is a problem that an uncertain mechanism must be used (for example, see Patent Document 3).

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a label printing and sticking device of the present invention will be described with reference to the drawings.

  1 to 4 show an embodiment of the label printing and sticking device of the present invention.

  The label printing and sticking device La includes a label printing mechanism 1 that prints on the label L of the label continuous body L0 without mount, and a label separation that separates the label L printed by the label printing mechanism 1 from the label continuous body L0. A mechanism 2 and a label sticking mechanism 3 for sequentially sticking the label L separated from the label continuous body L0 to the adherend W transported by the transport mechanism 4 and driving the platen roller 11 of the label printing mechanism 1 The stepping motor 12 is used as the source, the brushless DC motor 32 is used as the driving source of the label transfer belt 31 of the label sticking mechanism 3, and the stepping motor 12 and the brushless DC motor 32 are driven during label printing by a control mechanism (not shown). Synchronize the speed and stop the stepping motor 12 and the brushless DC motor 32 when the label is separated. Is, and so as to be synchronized with the conveying speed of the attached material W being conveyed the driving speed of the brushless DC motor 32 at the label sticking by the transport mechanism 4.

  The label continuous body L0 without mount is printed on the front surface, and an adhesive layer is formed on the back surface. Further, the label continuous body L0 is further spaced at a predetermined interval so that one piece of the label L can be accurately separated from the label continuous body L0. What formed the weak cut parts, such as perforation, can be used conveniently.

  The label printing mechanism 1 is for printing on the label L of the label continuum L0. The label printing mechanism 1 uses a stepping motor 12 as a drive source for the platen roller 11, and the platen roller 11 sandwiches the label L of the label continuum L0. The print head 13 is provided at the corresponding position, and the label detection sensor 14 for detecting the position of the label L of the label continuous body L0, for example, the weakly separated portion, is provided at the introduction position of the label continuous body L0.

The label separating mechanism 2 is for separating the label L printed by the label printing mechanism 1 from the label continuum L0. In this embodiment, the platen roller 11 and the print head 13 of the label printing mechanism 1, By pressing the chopper against the fragile separating portion of the label continuous body L0 that is stretched between the label transfer belt 31 and the nip roller 34 of the label applying mechanism 3, the piece of label L is cut at the fragile separating portion. I try to separate.
In addition, when using the label continuous body L0 in which the weak cut-off portion is not formed, a cutter is used instead of the chopper.

  The label sticking mechanism 3 is for sticking the label L separated from the label continuum L0 to the article W being transported by the transport mechanism 4 in order, and driving the label transfer belt 31 of the label sticking mechanism 3 A brushless DC motor 32 is used as a source, and a label transfer belt 31 is disposed at the base end portion of the label sticking mechanism 3. The driving roller 33 a is driven by the brushless DC motor 32 and a driven roller disposed at the distal end portion. And a fan motor on the back side of the label transfer belt 31 so that the label transfer surface 31a of the label transfer belt 31 can adsorb the printing surface side of the label L. A suction mechanism 35 comprising:

By the way, in this embodiment, the label transfer belt 31 of the label sticking mechanism 3 is installed so as to be inclined such that the label transfer surface 31a faces obliquely upward.
Here, the inclination angle of the label transfer surface 31a is preferably set to about 30 ° to 60 ° (45 ° in the present embodiment).
As a result, the label printing surface 31a is attracted to the label transfer surface 31a, and the driven roller 33b disposed at the tip of the label applying mechanism 3 via the label transfer belt 31 feeds the object W to be attached. In addition to the pressing action of the label L, the operation of sticking the label L to the bottom surface of the object W to be pasted through the adhesive layer formed on the non-printing surface side of the label L smoothly and reliably. Can be done.

Further, the label sticking mechanism 3 is arranged so that the position of the tip of the label transfer belt 31 can be adjusted with respect to the transport surface Le of the article W to be stuck of the transport mechanism 4.
Specifically, the leading end of the label transfer belt 31 is inserted between the upstream object transport belt 4a and the downstream object transport belt 4b constituting the transport mechanism 4, and the position of the front end is determined. When the bottom surface of the object W to be affixed with the label L is flat, the label is attached to the bottom surface of the object W to be depressed so that it is substantially flush with the transport surface Le. It is preferable that the transfer belt 31 is disposed so as to protrude upward from the conveyance surface Le so that the tip of the transfer belt 31 contacts.
In this case, the adjustment of the position of the leading end of the label transfer belt 31 is performed by adjusting the mounting position of the label applying mechanism 3 because the label applying mechanism 3 is not connected to the label printing mechanism 1 or the label separating mechanism 2. Can be performed by adjusting the entire label attaching mechanism 3 up and down or by swinging around the base end of the label attaching mechanism 3.
Thereby, the label L can be reliably guided to the predetermined position on the bottom surface of the article W to be pasted.

  Next, the operation of this label printing and sticking device La will be described.

  At the time of label printing, as shown in FIG. 2, the control mechanism synchronizes the driving speeds of the stepping motor 12 of the label printing mechanism 1 and the brushless DC motor 32 of the label sticking mechanism 3, and specifically, the label printing mechanism 1 By making the peripheral speed of the platen roller 11 and the label transfer speed of the label transfer belt 31 of the label sticking mechanism 3 the same (for example, 100 mm / s), the print head is fed out while feeding the label L from the label continuous body L0. 13 to perform predetermined printing.

  At the time of label separation, as shown in FIG. 3, the stepping motor 12 of the label printing mechanism 1 and the brushless DC motor 32 of the label sticking mechanism 3 are stopped by the control mechanism, and the platen roller 11 and the print head 13 of the label printing mechanism 1 are stopped. And pressing the chopper of the label separation mechanism 2 against the weak separation portion of the label continuous body L0 in a state of being stretched between the label transfer belt 31 and the nip roller 34 of the label sticking mechanism 3, thereby causing the weak separation. A piece of label L is cut off at the part.

  At the time of label sticking, as shown in FIG. 4, the control mechanism synchronizes the driving speed of the brushless DC motor 32 of the label sticking mechanism 3 with the transport speed of the article W being transported by the transport mechanism 4, and In this case, the label transfer speed of the label transfer belt 31 of the label sticking mechanism 3 and the transport speed of the article W being transported by the transport mechanism 4 are the same (for example, 400 mm / s). The label L separated from the body L0 is stuck on the adherend W being transported by the transport mechanism 4.

  According to this label printing and sticking device La, the label continuous body L0 without mount is used, and the stepping motor 12 of the label printing mechanism 1 and the brushless DC motor 32 of the label sticking mechanism 3 are driven by the control mechanism by a simple mechanism. By controlling, the label continuum L0 being printed is pulled more than necessary, and printing and labeling operations on the label L can be efficiently performed without causing problems such as print elongation.

  In the label printing and sticking device La of the above embodiment, the form in which the label L is stuck to the bottom surface of the object W to be stuck being conveyed above the label sticking mechanism 3 has been described. However, the label printing and sticking device La is described. By appropriately setting the arrangement of the label sticking mechanism 3 and the transport mechanism 4, the label L can be stuck on the upper surface of the article W being transported below the label sticking mechanism 3. The label L can be affixed to the side surface of the adherend W being transported laterally.

  As mentioned above, although the label printing and sticking device of the present invention has been described based on the embodiments thereof, the present invention is not limited to the configurations described in the above embodiments, and the configurations thereof are appropriately made within the scope not departing from the gist thereof. Can be changed.

  The label printing and pasting apparatus according to the present invention efficiently performs printing and label pasting work on a label without causing problems such as printing elongation due to a continuous mechanism of the label being pulled more than necessary by a simple mechanism. Since it can be performed, it can be used suitably for label printing and labeling application for a continuous substrateless label.
