Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a thread guide mechanism of a tag printing device with a thread, and in particular, a single-leaf tag is sent out one by one to perform printing on the tag. The present invention relates to a thread guiding mechanism of a thread tag printing device.

(Prior Art) Conventionally, each single leaf tag is sent out from a tag hopper that stores a plurality of single leaf tags attached with threads for hanging on a product etc. into a predetermined transport path and a predetermined printing is performed. A threaded tag printing device is known in which a printing tag is discharged and stored in a stacker or the like after printing by a mechanism.

However, when the single-leaf tags to which the thread for hanging is attached are sent out one by one and conveyed in a predetermined conveyance path, the thread is also pulled out into the conveyance path, This thread has a predetermined length, is formed in a closed loop shape, and swings back and forth and left and right depending on the transport state of the single-leaf tag during transport, so various mechanisms and parts inside the printing apparatus are provided. May interfere with the transportation of the single leaf tag.

Also, if the part to which this thread is attached is the side edge surface in the transport direction of the single-leaf tag, this thread easily enters the surface of the single-leaf tag, so a removal mechanism that removes this thread from the surface of the single-leaf tag, that is, its printed surface It is necessary and there is a problem that this removing mechanism becomes complicated. Therefore, it is easier to remove or treat the thread by attaching the thread to the trailing edge of the single-leaf tag, but the thread follows the rear of the single-leaf tag to be transported. The swaying of the yarn in the front-rear direction and the left-right direction as described above may be further increased.

(Problems to be solved by the invention) The present invention has been made in view of such circumstances, and a thread for feeding out the single-leaf tags one by one from a tag hopper in which a plurality of single-leaf tags with threads are stacked for printing by a printing mechanism.

A case where printing is performed on the single-leaf tag T using the thread-attached tag printer 1 having the above-described configuration will be described below.

First, the thermal transfer ink ribbon R is loaded into the tag printing device 1 with a thread, and a desired number of single-leaf tags T are loaded into the tag hopper 3 to start printing.

When this printing is started, one sheet of single-leaf tag T is delivered from the tag hopper 3 to the intermediate transport mechanism 5 by the delivery roller 16. The thread S attached to the fed single-leaf tag T is the tag mounting frame 11 in the thread pressing mechanism 1B.
It is pressed in a state that it is bundled together with the other thread S between the thread pressing surface 11B and the cushion member 13 of the thread pressing member 12, but this pressing force pulls out only one from the bundle. Since the cushion member 13 is deformable when the yarn S is pulled out, the yarn S of the single-leaf tag T that is sent out is pulled out from this bundle without being entangled with other yarns S. As the single-leaf tag T is transferred, it passes through the thread passing notch 11F and is further guided in the thread groove 15.

The single-leaf tag T sent from the sending mechanism 4 passes through the intermediate transport mechanism 5 and the pusher roller mechanism 6, is printed by the printing mechanism 7, and is then stored in a predetermined stacker or the like by the discharging mechanism 8. It will be. Moreover, during such feeding and conveyance, the bobbin thread S is started from the tag device frame 11 and is always guided to the thread groove frame 14 on the left and right sides thereof. Therefore, even during conveyance and printing along the conveyance path 1C. The possibility of being caught by other mechanisms or parts is extremely low.

When a thread is attached to the side edge portion of the single-leaf tag, a mechanism similar to the above-described thread guide mechanism 1A can be arranged on the side surface of the single-leaf tag.

(Effect of the Invention) As described above, according to the present invention, the thread passing notch of the tag mounting frame is formed so as to face the thread groove, and the tag is pulled out one by one when the single leaf tag is delivered. Since the moving yarn is always guided to the yarn groove frame, the single leaf tag with the yarn can be smoothly and stably conveyed and printed without the yarn being entangled in various mechanisms or parts in the middle of the conveying path. .
