Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paperless label feeding device provided with an auxiliary peeling mechanism so that a paperless (peeling sheet) less label wound in a roll suitable for an automatic label pasting machine can be easily peeled off from a roll state. .
[0002]
[Prior art]
In the label without mount, since the pressure-sensitive adhesive is applied to the back surface of the label, the adhesive surface comes into contact with the surface of the label when it is rolled. Generally, the surface of the label is subjected to a non-adhesive treatment, but since it is wound in a roll shape, it has a defect that prevents smooth feeding due to its adhesive action.
[0003]
[Problems to be solved by the invention]
In view of the above-mentioned conventional defects, the present invention requires a smooth peeling action of a label without a base sheet wound in a roll shape. For this purpose, an auxiliary peeling mechanism is provided, the label feeding action is good, and the printing accuracy is high. The purpose is to provide an automatic labeling machine.
[0004]

A roll unwinding means comprising a drive roller that is transmitted to a motor and forcibly rotated in the vicinity of the supply delivery port of the unpaid label feeding device, and a turning member configured to be in pressure contact with the drive roller;
First elastic holding means provided on a movable rod connected to the driving roller and the turning member of the roll unwinding means;
An auxiliary peeling mechanism consisting of
By means of the first elastic holding means of the auxiliary peeling mechanism, the turning member of the roll unraveling means is always in an elastically biased state on the outer peripheral surface of the mountless label that has become a roll,

DETAILED DESCRIPTION OF THE INVENTION
As shown in the cross-sectional view of FIG. 3, the label 2 without a mount wound in a roll shape has a pressure-sensitive adhesive 21 on the back side of the label substrate 20, and a non-adhesive layer such as silicon on the surface thereof. 22 is given. Therefore, as shown in the apparatus explanatory diagram of FIG. 1 (first embodiment), when the label L without backing paper is wound in a roll shape, the pressure-sensitive adhesive 21 contacts the surface of the label base material 20, Its feeding (peeling) property is poor.
[0006]
The overall configuration will be described with reference to FIG. 1 showing the first embodiment. A label L without mount is wound around the supply shaft 1 in a roll shape.
[0007]
Next, in order to smoothly draw out the non-mounting label L wound in the form of a roll, a roll unwinding means 6 is disposed in the supply feed outlet 3 portion. The roll loosening means 6 is a drive roller 5 that is connected to the motor M and forcibly rotates, and a turning roller 4 a configured to synchronize with the roller 5.
[0008]
The roll unraveling means 6 comprising the turning roller 4a and the drive roller 5 is formed into the roll shape by the first elastic holding means 10 that presses the outer peripheral surface of the non-mounting label 2 wound in the roll shape. The configuration is such that the outer peripheral surface of the wound non-mounting label 2 is elastically pressed. Specifically, the drive roller 5 and the turning roller 4a are integrally attached to the guide plate 7, and a guide slit 8 is formed in the guide plate 7. In the guide slit 8, a movable rod 9a connected to the rollers 4a and 5 is engaged. Further, the movable rod 9a is provided with a tension spring 9b, and always exhibits an elastic biasing state on the outer peripheral surface of the mountless label 2 in which the turning roller 4a is rolled.
[0009]
Accordingly, when the roll-like non-mounting label 2 is fed out and its diameter is reduced, it follows this and rises in FIG.
[0010]
Further, a movable guide roller 11 having a second elastic holding means 15 is provided, and a non-mounting label L formed in a belt shape is stretched over the movable guide roller 11 from the roll unwinding means 6. The movable guide roller 11 is displaced from the motor stop position A to the motor drive position B and functions as a tension arm. Specifically, the second elastic holding means 15 of the movable guide roller 11 has a tension spring 14 attached to the shaft 12 of the movable guide roller 11, and the movable roller 11 is always elastic in the motor stop position A direction. Energized. That is, since the mountless label L is turned to the movable guide roller 11, the roller 11 is pulled in the direction of the motor drive position B, and the shaft 12 passes through the guide slit 13 from point A to point B. It is configured to be freely movable from point B to point A.
[0011]
Thus, when it is located at point B, the power is turned on, the motor M of the roll loosening means 6 is driven, the drive roller 5 rotates, and when it is returned to point A by the action of the tension spring 14 from point B, the power is turned off. Thus, the motor M stops.
[0012]
Next, the strip-like non-mounting label L to be guided is subjected to desired printing through a guide roller 17 and printing means 18 including, for example, a platen roller and a thermal head. The printing means 18 may be thermal transfer.
[0013]
Next, a label L having a predetermined length is obtained by operating the cutting means 19. At the front end of the printing means, a label is attached to the surface of an article that is mounted and transported on a conveyor (not shown) arranged orthogonal to the printing means, and a sticking roller or the like (not shown) attached to the machine. It is to stick.
[0014]
Next, the second embodiment of the present invention shown in FIG. 2 is substantially the same as the configuration described in the first embodiment of FIG. 1, and the different configuration is that the turning member of the roll unwinding means 6 is used as a turning plate. It is an example changed to 4b. In addition, the same code | symbol as 1st Example shows the same member, The description is abbreviate | omitted. Further, the first elastic holding means 10 for bringing the outer peripheral surface of the roll-shaped mount label 2 into a pressure contact state, the second elastic holding means 15 for the movable guide roller 11 and the like are omitted in the drawings.
[0015]
【The invention's effect】
As described above, the present invention provides a paperless label feeding device for peeling a paperless label wound in a roll shape from a rolled state to a fed state.
A roll unwinding means comprising a drive roller that is transmitted to a motor and forcibly rotated in the vicinity of the supply delivery port of the unpaid label feeding device, and a turning member configured to be in pressure contact with the drive roller;
First elastic holding means provided on a movable rod connected to the driving roller and the turning member of the roll unwinding means;
An auxiliary peeling mechanism consisting of
By means of the first elastic holding means of the auxiliary peeling mechanism, the turning member of the roll unraveling means is always in an elastically biased state on the outer peripheral surface of the mountless label that has become a roll,
Since the label without the mount is peeled from the rolled state to the extended state,
The label without a roll-like mount can be smoothly fed from the rolled state to the fed state. Accordingly, the tension is not applied to the feeding label, so that clear printing is performed.
