Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a label peeling device for peeling a label from a roll of backing paper.

2. Description of the Related Art Conventionally, a printer section and a label peeling body are provided in the path of pulling out a liner wound into a roll, and the liner pulled out by a feed roller is bent at an acute angle by the label peeling body, and the label is removed at this bending part. There are products that can be peeled off from the backing paper and affixed to products, etc.

Problems to be Solved by the Invention However, as the remaining amount of the backing paper decreases, the winding diameter becomes smaller, so the label attached to the backing paper in this area becomes curly and curved. Therefore, there is a problem in that the label on the label peeling body is curved in the direction of bending of the mount while being peeled off, which causes problems in pasting the label on products or the like. This tendency is particularly strong for horizontally long labels. For example, labels have recently been used to display titles on cassette tapes, but this type of label is elongated and curved, making it difficult to position the label when pasting it on a cassette tape case.

Means for Solving the Problems A holding part is provided to hold a long mount having a large number of labels pasted thereon and wound into a roll, and this mount is placed in the path of the mount which is pulled out from the holding part. a label peeling body that refracts the label, a label presser having a contact portion that contacts the label on the label peeling body is provided perpendicularly to the label feeding direction, and receiving portions that abut the outer periphery of both ends of the label presser; are provided, and a pressing plate is provided opposite to these receiving portions and resiliently engaged with the label holder.

Therefore, the contact portion of the label presser is brought into contact with the curled label to correct the curling of the label.

In addition, by elastically retracting the pressing plate, attachment and detachment of the label presser is facilitated.

Example An embodiment of this invention will be described based on the drawings.

A shaft-shaped holding part 3 for rotatably holding a mount 2 wound into a roll is installed on the opposing b-side plate 1, and also includes a guide roller 4, a platen 5, a feed roller 6,
A pinch roller 7 is rotatably provided. Further, a thermal head 8 is attached to the side plate 1.

Next, a unit lo having a horizontally long label peeling body 9 is provided. This unit 10 includes a label peeling body 9
It consists of a bell holder 11 parallel to the label peeling body 9, and a plate spring 13 which is a pressing plate that elastically engages the label holder 11 by the force of a spring 12. The label presser 11 is shaped like a round bar, and has a contact portion 15 on its lower outer periphery that makes line contact with the label 14 affixed to the mount 2.
is formed. In addition, a spacer 16 is a receiving part that defines a gap in the center between the label peeling body 9 and the label presser 11.
is fixed to the top surface of the end of the label peeling body 9. Furthermore, base portions 17 are integrally formed at both ends of the label peeling body 9, and screws 18 for holding the plate springs 13 in a vertically movable manner and for holding the coil springs 12 are screwed into these base portions 17. Furthermore, a pin 19 is erected which is loosely fitted to the end of the plate spring 13 and prevents the plate spring 13 from rotating. Such a unit 10 is fixed by tightening each end of the label peeling body 9 to the side plate 1 with one screw 20, but the unit 10 can be rotated around these screws 20 located on the same axis. unit 10 by tightening the screws 20 while keeping the upper surfaces of both ends of the label peeling body 9 and the outer peripheries of both ends of the label presser 11 in contact with the fixed shafts 21 installed on the inner surface of the side plate 1 on the same axis. is positioned and fixed.

In such a configuration, printing on the label 14 is performed by transferring ink (not shown) from an ink ribbon using the thermal head 14. Then, when the platen 5 and the feed roller 6 are rotated counterclockwise and the mount 2 is pulled out from the holding section 3 while being bent by the label peeling member 9, the stiff label 14 is peeled off from the mount 2. Mount 2
When the winding diameter of the label 14 becomes smaller, the label 14 attached to the mount 2 in this area tends to curl, but it is straightened in the process of contacting the label presser 11 on the label peeling body 9. At this time, the label presser foot 11 receives resistance from the strong label 14, but it presses the label 14 in a line contact state and can also retract the plate spring 13 upward, so the label presser foot 11
It does not obstruct the passage of 4. The pressure of the plate spring 13 against the resistance of the label 14 can be freely adjusted by turning the screw 18 and varying the strength of the coil spring 12.

Therefore, even when a laterally long label 14 is attached to the narrow side surface of the cassette tape case 22, the curl of the label 14 is corrected, so that it can be attached at the correct position.

Further, the label presser 11 can be removed with one touch by bending the plate spring 13 upward. As a result, the label presser 11 passes from the back side of the label 14 through the mount 2.
The adhesive adhering to the label 14 can be cleanly and reliably cleaned, and staining of the surface of the label 14 can be prevented. After cleaning, the label presser 11 can be attached with one touch by bending the plate spring 13 upward. in this case,
The label presser 11 is supported and positioned by the spacer 16 and the fixed shaft 21.

In the embodiment, the label peeling body 9 and the label presser 11
The spacer 16 was used to set the gap in the center between the mount 2 and the label 14 to be slightly larger than the sum of the thickness of the mount 2 and the thickness of the label 14. 9 or the end of the label presser 11 may be formed integrally.

Further, by forming a recess along the outer periphery of the label presser 11 in the plate spring 13, the label presser 11 can be positioned without contacting the fixed shaft 21.

Furthermore, by engaging the free end of the plate spring 13 with the label presser 11, the base of the plate spring 13 is fixed and the coil spring 12 is omitted, or instead of the plate spring 13, a non-elastic plate can be used as a coil. It may be biased by a spring 12. In either case, the label presser 11 can be held elastically.

Furthermore, in order to press the label 14 in a line contact state,
It is also possible to use a rod-shaped label presser with a polygonal cross-section to press the label 14 using the ridge lines of the corners.

Effects of the Invention Since the present invention is configured as described above, it is possible to correct the curling of the label by bringing the contact part of the label presser into contact with the curling label, and therefore automatically remove the label that has peeled off from the backing paper. Even if the labels are to be pasted, they can be pasted in the correct position.Furthermore, the pressure plate can be retracted and the label presser can be attached and detached with a single touch.
Adhesive adhering to the label holder from the label can be easily and reliably cleaned, and the surface of the label can thereby be prevented from becoming dirty.
