CONSTITUTION:A nip roller 26 is provided on a feeder roller 20 rotatable by a motor 24 in such manner as to retainably pass between itself and the feeder roller a strip of the backing paper carrying a sequence of labels 14 so as to feed the backing paper from a retaining reel 12. A label separating plate 30 is provided forward of the feeder roller 20 to sharply turn the backing paper 16 during its travel in order to remove a label 18 therefrom. A nip roller 32 is also provided under the feeder roller 20 to lead the backing paper 16 from its turn at the label separating plate 30 to a take-up roller in cooperation with the feeder roller 20. At this time, a tensile force is exerted on the backing paper 16 traveling between the label separating plate 30 and the nip roller 32 to facilitate the drawing thereof from the retaining reel 12.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a cover adhering device, and in particular, to a belt-like release sheet material that is temporarily and releasably attached at intervals in the longitudinal direction. The label that is there! J1 Relates to a label sticking device for peeling off from a release sheet material and sticking it on an article.

(Prior Art) FIG. 4 is an illustrative view of the main parts of a conventional example of a label pasting device which is the background of the present invention. This label sticking device 1 includes a holding reel 2, and the holding reel 2 holds a continuous label body 3 in the form of a roll. The label continuous body 3 includes a belt-shaped peeling stand 4, and labels 5 are temporarily and releasably attached to the peeling stand 4 at intervals in the longitudinal direction.

Then, this label continuum 3 is passed through rollers etc.
It is guided to the peeling plate 6, where the peeling table 4 is abruptly folded back. Further, this peeling paper 4 is guided between a feeder roller 7 and a nip roller 8, and is transported by these rollers 7 and 8 in its longitudinal direction. In this way, by rapidly folding back the release mount 4 and transporting it, the label 5 is peeled off from the release mount 4 by the release plate 6 and is supplied to the article (not shown). Note that the peeling paper 4 that has passed between the feeder roller 7 and the nip roller 8 is wound up into a roll by a take-up reel 9.

(Problem to be Solved by the Invention) However, in such a conventional label sticking device 21, for example, when forming the outline of the label 5 with a knife, a peeling backing paper with unnecessary cuts, etc., has a low tensile strength. If a small release mount 4 is used, for example, when transporting the release mount 4 in order to peel off the label 5 from the release mount 4, the release mount 4 can
It was often cut between the peeling plate 6 and the feeder roller 7. This is because in this label sticking device 1, when the peeling base 4 is transferred, the peeling liner 4 is transferred by the feeder roller 7 and nip roller 8 provided on the downstream side of the peeling plate 6. At least the tensile force required to pull out the peeling base 4 to which the label 5 is attached is applied from the holding reel 2, and the tensile force required to peel the label 5 from the peeling mount 4, which is a relatively large tensile force. It is.

Once the peeling stand 4 is cut in this way, the label sticking device 1 is no longer able to transport the peeling stand 4, that is, to peel the label 5 from the peeling mount 4. Therefore, in conventional labeling devices, only release sheet materials with high tensile strength can be used.

Therefore, the main object of the present invention is to provide a labeling device that can be used even with release sheet materials having low tensile strength.

(Means for Solving the Problems) This invention provides a method for holding strip-shaped release sheet materials to which labels are temporarily and releasably attached at intervals in the longitudinal direction so as to be transportable in the longitudinal direction. holding means for pulling out the release sheet material from the holding means and transporting the release sheet material in its longitudinal direction; The conveyance means cooperates with the feeder roller between the feeder roller provided on the conveyance path of the release sheet material, the holding means and the peeling means. a first nip roller that is provided so as to be able to work to pinch the release sheet material; and a second nip roller that is provided downstream of the peeling means to be able to work with the feeder roller and to pinch the release sheet material. It is a device.

(Operation) The release sheet material held by the holding means is transferred to the peeling means side by the feeder roller and the first nip roller of the transfer means.

The release sheet material that has been transported to the peeling means side by the feeder roller and the second Niso roller of the transport means is
It is pulled in its longitudinal direction so that it is sharply folded back at the tip of the peeling means. In this case, the label is peeled off from the release sheet material by the peeling means.

Therefore, when transporting the release sheet material, no tensile force is applied to the release sheet material existing between the first nip roller and the second nip roller of the transport means to pull the release sheet material out from the holding means. That is, only a relatively weak tensile force is applied to the release sheet material.

(Effects of the Invention) According to the present invention, only a relatively weak tensile force is applied to the release sheet material, so even release sheet materials with low tensile strength can be used.

Further, since only a relatively weak tensile force is applied to the release sheet material, it is possible to speed up the transportation of the release sheet material or the feeding out of the label.

The above-mentioned objectives of this invention. Other purposes. Features and advantages will become more apparent from the following detailed description of the embodiments with reference to the drawings.

(Embodiment) Fig. IA and Fig. IB each show an embodiment of the present invention, with Fig. IA being a side view thereof, and Fig. IB being an illustrative view thereof. This label pasting device 10 has a base 11
A holding reel 12 as a holding means is provided on the upper part of the base body l1. This holding reel 12 includes
A continuous label body 14 is held in a roll shape.

The label continuous body 14 includes a release mount 16 as a strip-shaped release sheet material, and labels 18 are attached to the release mount 16 at intervals in the longitudinal direction thereof. The release mount 16 includes a strip-shaped sheet material such as paper or resin, and a release agent layer such as silicone is applied to the surface of the sheet material to form a release agent layer. There is.

Therefore, the label l8 is temporarily and releasably attached to the release mount 16.

Further, below the holding reel 12, a feeder roller 20 is provided that guards a part of the transport means. The shaft 20a of this feeder roller 20 is connected to a motor 24 via a coupler 22, as shown in particular in FIG. IB. Therefore, the feeder roller 20 can be rotated by this motor 24 or the like.

Furthermore, a first nip roller 26 is provided above the feeder roller 20 so as to be able to nip the continuous label body 14 in cooperation with the feeder roller 20 .

is transferred to the peeling plate l-30 side. This peeling plate 30 is for peeling the labels 18 of the label continuous body 14 from the peeling table 16 by sharply folding back the peeling table 16 of the label continuous body 14.

Further, a second nip roller 32 is provided below the feeder roller 20 so as to be able to come into contact with the feeder roller 20 . Then, between the feeder roller 20 and the second nip roller 32, the release mount 16 that has been sharply folded back by the release plate 30 is guided. Therefore, feeder roller 2
By rotating the label l8, the label l8 of the label continuous body 14 can be peeled off from the peeling mount 16 by the peeling plate 30 and fed out forward. In this case, no tensile force is applied to the release mount 16 between the release plate 30 and the second nip roller 32 for pulling out the release mount 16 from the holding lever 12.

This is because the release paper 1 pulled out from the holding reel l2
6 is a feeder roller 20 and a first nip roller 2
6, it is transferred to the peeling plate 30 side. Therefore, only a relatively weak tensile force is applied to the release mount l6. Therefore, in this labeling device 10, even a release liner 16 or a release sheet with low tensile strength, such as a release liner with unnecessary cuts made when shaping the outline of the label 18 with a knife, can be used. I can do it. In addition, since only a relatively weak tensile force is applied to the release liner l6, the transfer of the release liner l6 or the label 1
It is also possible to increase the speed of drawing out the 8.

Note that the feeder roller 20 and the second nip roller 3
The peeling table 16 sent by 2 is wound up into a roll by a winding roll 34.

Further, below the above-mentioned peeling plate 30, etc., a conveyor 40 is provided as a conveying means for conveying the adhered object l00 in the direction in which the label 18 is pulled out. Therefore, the adhered object 10 conveyed by this conveyor 40
