Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a label issuing device capable of detecting the remaining amount of a roll-shaped label.

[0002]

[Prior Art]

 In general, a label issuing device pulls a roll-shaped label held in a holder from the holder to perform desired printing, peels off the printed label from the label mount, and supplies the label to a pasting device. There is. In such a label issuing device, in order to detect that the remaining amount of the roll-shaped label is small, for example, the following methods (1) and (2) have been adopted. (1) The number of labels to be issued is set in advance in the counter, and a signal is output when the number of labels is counted.

(2) A swingable arm having a base end pivotally supported is provided, and the tip end thereof is brought into contact with the outer circumference of the label roll. A micro switch that operates by swinging the arm is installed near the arm. According to this configuration, when the label is issued and the diameter of the roll becomes smaller, the arm swings and the microswitch operates to output a signal.

[0005]

[Problems to be solved by the device]

 The first method of counting the number of issued labels and comparing them with the set number has a problem that the set number has to be changed according to the label winding diameter and the operation is complicated.

In the method of using the arm that swings depending on the diameter of the roll, the arm is difficult to handle, which may be a hindrance during label replacement, and in some cases, the arm may be damaged. Further, since the arm contacts the label, it may damage the label, limiting the types of labels that can be applied.

It is an object of the present invention to provide a label issuing device capable of detecting the remaining amount of a roll-shaped label with high reliability.

[0008]

[Means for Solving the Problems]

 The label issuing device of the present invention issues a roll-shaped label held by a holder. The label issuing device is provided with an optical sensor for detecting the remaining amount of the label by detecting the side end surface of the roll-shaped label. It is characterized by that.

[0009]

[Action]

 The remaining amount of the label is detected by detecting the side end surface of the roll-shaped label by the optical sensor.

【Example】

 1 and 2 show a label holder device provided in a label issuing device according to an embodiment. A center shaft 2 is erected and fixed to a main body 1 of the holder device. A shaft member 3 which is rotatable with respect to the central shaft 2 is fixedly provided in a central position portion of the central shaft 2 in the axial direction.

A fixing member 4 is provided on the inner side of the central shaft 2 so as to be fixed to the central shaft 2 by a screw 4 a, and a rotatable reel body 6 is provided on a surface shaft portion 4 b of the fixing member 4. Is provided. The reel body 6 is a rectangular parallelepiped flat plate as shown in FIG. A circular rotatable reel body 7 is provided in front of the central shaft 2. Cutouts 8a and 8b are provided on the front surface of the reel body 7, and support grooves 9a are provided on the sides of the cutouts 8a and 8b. The end portions of the guide members 10a and 10b are inserted and axially supported. Step portions 11 and 12 are provided on the side portions of the cutout portions 8a and 8b and the support groove 9a. Therefore, the guide members 10a and 10b are in an inverted state when the label 5 is mounted on the reel bodies 6 and 7, and are in an upright state after the label is held, as shown in phantom lines in FIG. The end face can be held.

The adjusting plate 1 is rotatably supported by the shaft member 3. Long holes 15a and 15b are formed at both ends of the adjusting plate 15, respectively. The reel bodies 6 and 7 are interlockingly connected to each other by engaging pins 16 and 17 with the elongated holes 15a and 15b of the adjusting plate 15, respectively. A guide rod 18 protruding from the inner end surface of one reel body 7 is inserted through the other reel body.

According to the above structure, the paper ring 5a of the label 5 in a roll shape can be held by the reel bodies 6 and 7, and the label 5 can be held rotatably with respect to the central axis 2. In addition, by loosening the screw 4a, the reel bodies 6 and 7 interlocked and coupled by the adjusting plate 15 can be slid in the axial direction with respect to the central axis 2, and the interval between the two can be set arbitrarily so that the width It can also hold different labels. Even if labels with different widths are held, the position of the center line of the label in the width direction does not change.

Next, the main body 1 is provided with a reflection type optical sensor 20 toward the reel body 6 side. The optical sensor 20 is set at a position that detects the vicinity of the paper ring 5a on the inner end surface 5b of the label 5 mounted on the reel bodies 6 and 7 of the holder device. The optical sensor 20 has a variable measurement range. Therefore, as described above, the labels of different widths are held by changing the interval between the reel bodies 6 and 7, and even if the distance between the inner end surface of the label and the main body 1 is changed, the vicinity of the label paper ring can be detected without any trouble. can do.

According to the holder device of this embodiment, the end face of the label 5 close to the paper ring 5a can be directly optically detected regardless of the label winding diameter and the label width. That can be reliably detected.

In this embodiment, the mounting position of the optical sensor 20 with respect to the main body 1 is constant, but if the mounting position of the optical sensor 20 can be changed along the radial direction of the label 5, the label 5 can be arbitrarily set. It is possible to get a signal when the remaining amount is reached.

In the present embodiment, the reel body 6 is an elongated rectangular shape and does not obstruct the detection position of the optical sensor 20, but when the reel body 6 is disk-shaped and covers the end surface 5 b of the label 5, A hole or a notch may be provided in a portion corresponding to the detection position of the optical sensor 20, or the reel body 6 itself may be made of a transparent material.

Although the reflection type optical sensor 20 is used as the optical sensor in the present embodiment, a transmission type optical sensor can also be used. Although the label roll is described in this embodiment, the remaining amount of the roll-shaped ribbon can be detected in the same manner as in the ribbon supply body that is thermally transferred to the label as shown in FIGS. 3 and 4.

[0019]

[Effect of the device]

 In the label issuing device of the present invention, the side end surface of the label is detected by an optical sensor in a non-contact manner, so that the label remaining amount can be reliably detected without damaging the label. Moreover, since the end of the label can be accurately predicted by detecting the remaining amount, it is possible to shorten the downtime of the apparatus required for the label replacement and the like.
