Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label peeling device that peels a label from a roll-wrapped mount.

2. Description of the Related Art Conventionally, a printer unit and a label peeling body are provided in a drawing path of a roll-shaped mount paper, and the mount paper drawn out by a feed roller is refracted at an acute angle by the label peeling body, and a label is formed at the bending portion. There is one that is peeled off from the mount and attached to a product or the like.

Problems to be Solved by the Invention However, since the winding diameter becomes smaller as the remaining amount of the mount becomes smaller, the label attached to the mount at this portion has a curl and is curved. Therefore, there is a problem that the label on the label peeling body is curved in the refraction direction of the mount while being peeled off, which hinders the sticking to the product or the like. Especially, the longer the label is, the stronger the tendency is. For example, although the label of a cassette tape has recently been using a label, this type of label is long and narrow in the lateral direction, and if it is curved, it becomes very difficult to position it when the cassette tape is attached to the case.

Means for Solving the Problems A label peeling body in which a holding portion for holding a long-sized mount having a number of labels attached and wound in a roll is provided, and the mount drawn out from the holding unit is bent. And a label retainer having a contact portion that comes into contact with the label on the label peeling body at a right angle to the label feeding direction, and a support for holding both ends of the label retainer at both ends of the label peeling body. A part is attached, and a spacer is selectively interposed between both ends of the label peeling body and the label retainer by these supporting portions to connect the label peeling body and the label retainer to form a unit, This unit was joined to opposite side plates by a fastening member.

Action You can correct the curl of the label by contacting the contact part of the label retainer with a proper pressure to the label with the curl.
Further, by forming a unit by connecting the label peeling body and the label retainer with the support portions provided at both ends of the label peeling body by selectively interposing the spacer, the label can be labeled in unit by selecting the spacer thickness. The relative position between the peeling body and the label retainer can be easily adjusted, whereby the pressing state can be adjusted appropriately according to the thickness of the label and the strength of the waist to ensure the label peeling. Further, since the adjusted unit can be assembled to the side plate by the fastening member, the assembly is facilitated.

Embodiment An embodiment of the present invention will be described with reference to the drawings. A shaft-shaped holding portion 3 that rotatably holds a roll-mounted backing sheet 2 is provided on opposite side plates 1, and a guide roller 4, a platen 5, a feed roller 6, and a pinch roller 7 are provided. And are rotatably provided. Further, a thermal head 8 is attached to the side plate 1.

Next, a unit 10 having a horizontally long label peeling body 9 is provided. This unit 10 is a label peeling body 9
And a label retainer 11 parallel to the label peeling body 9 and a plate strip 13 which is a support portion elastically pressed against the label retainer 11 by the force of the coil spring 12. The label retainer 11 is in the shape of a round bar, and a contact portion 15 for contacting the label 14 attached to the mount 2 in a line contact state is formed on the outer periphery of the lower portion thereof. In addition, a spacer 16 that defines a gap between the label peeling body 9 and the label retainer 11 is fixed to the upper surface of the end portion of the label peeling body 9. Further, bases 17 are integrally formed at both ends of the label peeling body 9, and screws 18 for holding the plate spring 13 vertically movable and holding the coil spring 12 are screwed on the bases 17. Further, a pin 19 which is loosely fitted to the end of the plate spring 13 to prevent the plate spring 13 from rotating is provided upright. Such a unit 10 is fixed by fastening both ends of the label peeling body 9 to the side plate 1 with a single screw 20 which is a fastening member, but these screws 20 located coaxially are fixed. The unit 10 is rotated around the center, and the screw 20 while maintaining the state in which the upper surfaces of both ends of the label peeling body 9 and the outer circumferences of both ends of the label holder 11 are in contact with the fixed shaft 21 coaxially erected on the inner surface of the side plate 1. The unit 10 is positioned and fixed by tightening.

In such a configuration, printing on the label 14 is performed by transferring the ink (not shown) of the ink ribbon by the thermal head 14. Then, when the platen 5 and the feed roller 6 are rotated counterclockwise and the backing sheet 2 is pulled out from the holding portion 3 while being bent by the label peeling body 9, the strong label 14 is peeled off from the backing sheet 2. When the roll diameter of the mount 2 becomes smaller, the label 14 attached to the mount 2 in this portion has a curl, but is straightened in the process of contacting the label retainer 11 on the label peeling body 9. At this time, the label retainer 11 receives the resistance of the strong label 14, but the label 14 can be pressed in the line contact state and the plate strip 13 can be retracted upward, so that the passage of the label 14 is hindered. There is no such thing. The pressure of the plate spring 13 against the resistance of the label 14 can be freely adjusted by rotating the screw 18 to change the strength of the coil spring 12.

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

Further, the label peeling body 9 is positioned and fixed by loosening the screw 20 and rotating around the screw 20 as a fulcrum, and tightening the screw 20 while maintaining the state of being in contact with the fixed shaft 21. As a result, the two surfaces of the label peeling body 9 that are bordered by the edges can be aligned with the traveling direction of the mount 2.

Further, the label retainer 11 can be removed by one-touch by bending the plate spring 13 upward. As a result, the label holder 1 is passed from the back surface of the label 14 through the mount 2
The adhesive adhered to 1 can be cleaned cleanly and surely, and the surface of the label 14 can be prevented from being soiled. The label retainer 11 can be attached after cleaning by one-touch by bending the plate rib 13 upward. In this case, the space between the label retainer 11 and the label peeling body 9 is set by the spacer 16, and the fixing shaft 21 positions the mount 2 in the traveling direction.

In the above embodiment, the label peeling body 9 and the label retainer 11
The spacer 16 was used to set the gap in the central part of the label to a dimension slightly larger than the sum of the thickness of the mount 2 and the thickness of the label 14. It may be formed integrally with the end of the label holder 9 or the label retainer 11.

Also, by engaging the free end of the elastic bar 13 with the label retainer 11, the base of the plate bar 13 is fixed and the coil spring 12 is omitted, or instead of the plate bar 13, a plate having no elasticity is supported. The plate may be used as a part and the plate may be biased by the coil spring 12. In any case, the label retainer 11 can be elastically pressed against the spacer 16 and the fixed shaft 21.

Furthermore, in order to press the label 14 in the line contact state,
It is also possible to use a rod-shaped label retainer having a polygonal cross section and hold the label 14 by the ridges of the corners.

EFFECTS OF THE INVENTION As described above, the present invention is provided with a holding portion for holding a long-sized mount having a number of labels attached and wound in a roll, and bending the mount drawn out from the holding part. A label peeling body is provided, and a label retainer having a contact portion that comes into contact with the label on the label peeling body is provided orthogonal to the label feeding direction, and both ends of the label retainer are provided at both ends of the label peeling body. A supporting portion for holding is attached, and a spacer is selectively interposed between both ends of the label peeling body and the label retainer by these supporting portions to connect the label peeling body and the label retainer to form a unit. Take shape
Since this unit is joined to the opposite side plates by the fastening members, it is possible to correct the curl of the label by bringing the contact portion of the label retainer into contact with the label with the curl at an appropriate pressure. By forming a unit by connecting the label peeling body and the label retainer by selectively interposing spacers by the support portions provided at both ends of the label peeling body,
By selecting the thickness of the spacer, the relative position of the label peeling body and the label retainer can be easily adjusted in unit.
As a result, the pressing state can be appropriately adjusted according to the thickness of the label and the strength of the waist, and the label can be reliably peeled off. Furthermore, the adjusted unit is assembled to the side plate by the fastening member. Therefore, there is an effect that the assembling becomes easy.
