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. The label peeling body has two surfaces bounded by the edges that bend the backing sheet and aligned with the feeding direction of the backing sheet, by connecting both end surfaces to opposite side plates with screws, and to the stoppers installed upright on these side plates. The outer surface around the axis of the label peeling body is brought into contact with the outer surface of the label peeling body, whereby the position of the label peeling body in the rotating direction is determined and the screw is tightened to fix the label peeling body.

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, the label on the peeling body of the label is curved in the refraction direction of the backing sheet while being peeled off, which causes a problem in sticking the label to a 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 holding portion is provided for holding a long-sized mount which has a number of labels attached and is wound in a roll shape, and a bent portion for bending the mount drawn out from the holding part is provided. A label peeling body formed at one end of a planar outer surface is provided, and a screw for connecting opposite side plates and both ends of the label peeling body so that a turning angle can be adjusted is provided. A label fixedly provided on each of the side plates with a stopper that comes into contact with the outer surface at a deviated position, and has a contact portion that is in contact with the label on the outer surface of the label peeling body orthogonal to the feeding direction of the label. A presser is provided, the base is fixed to the label peeling body, and the label presser is detachably pressed so as to elastically contact the outer surface of the label peeling body and the bent side of the stopper. The pressing body is the base It was movably attached to the part by urging it in one direction.

Action Even if the label has a curl, the curl can be corrected by pressing the label with the label retainer pressed by the pressing body and pressing it against the outer surface of the label peeling body,
Further, since the pressing body that presses the label retainer is movably attached to the base portion fixed to the label peeling body by urging it in one direction, the pressing body is opposite to the urging direction with respect to the base portion. The label retainer can be attached or detached by moving it to, and this makes it possible to easily and surely clean the adhesive attached to the label retainer, and to prevent the label surface from becoming dirty. Further, since the label retainer is attached by being pressed by the pressing body and abutting on the bent portion side of the stopper, its attaching position is also constant.

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 in which a bent portion for bending the mount 2 drawn out from the holding portion 3 is formed at one end of a planar outer surface is provided. The unit 10 includes the label peeling body 9 and a label retainer 11 arranged in parallel with the label peeling body 9.
The base 17 is fixed to the label peeling body 9 and to which the screw 18 and the pin 19 are fixed, and a pressing portion for pressing the label retainer 11 by the force of the coil spring 12 attached to the screw 18. It consists of a plate spring 13. The plate spring 13 is biased in one direction by the coil spring 12 and is movably attached to the base portion 17, that is, vertically movable. Since the pin 19 is loosely fitted to the end of the plate spring 13, the plate spring 13 is prevented from rotating. 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. Further, spacers 16 that define a gap in the central portion between the label peeling body 9 and the label retainer 11 are fixed to both ends of the upper surface of the label peeling body 9. Such a unit 10
Is fixed by fastening both ends of the label peeling body 9 to the side plate 1 with one screw 20, respectively, but these screws 20 which are located coaxially and serve as the center of rotation of the label peeling body 9 The unit 10 is rotated about the center of the label plate, and the fixed shaft 21, which is a stopper erected on the inner surface of the side plate 1 on the same axis, is coaxially mounted on both end upper surfaces of the label peeling body 9 and the label holder 1.
The unit 10 is positioned and fixed by tightening the screw 20 while keeping the outer circumferences of both ends in contact with each other.

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 mount 2 is positioned by the fixed shaft 21 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. Alternatively, the locking portion that restricts the movement of the label retainer 11 in the contacting / separating direction with respect to the label peeling body 9 is fixed to the fixed shaft
The same purpose can be achieved by forming the structure of No. 1 as well.

Further, by engaging the free end of the plate spring 13 with the label retainer 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 plate having no elasticity is coiled. It may be biased by the 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 having a bent portion formed on one end of a flat outer surface is provided, and a screw for connecting the opposite side plates and both ends of the label peeling body so that the turning angle can be adjusted is provided. A contact portion fixedly provided on each of the side plates to contact the outer surface at a position deviated from the center of motion, and contacting the label on the outer surface of the label peeling body orthogonal to the label feeding direction. A label retainer having a label retainer is provided, the base is fixed to the label remover, and the label retainer is detachable so as to elastically contact the outer surface of the label remover and the bent side of the stopper. Pressing body that presses against Since it is movably attached to the base part by urging it in one direction, even if the label has a curl, the label is pressed by the pressing body and pressed against the outer surface of the label peeling body. The curl can be corrected by doing so, and the pressing body that presses the label retainer is movably attached to the base portion fixed to the label peeling body by urging in one direction. The label retainer can be attached / detached by moving the pressing body in the direction opposite to the urging direction with respect to the section, which makes it easy to remove the adhesive attached to the label retainer.
In addition, it can be surely cleaned, the surface of the label can be prevented from being contaminated with it, and the label holder is pressed by the pressing body and abuts on the bent side of the stopper. The effect is that the mounting position is also constant.
