DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In FIG. 1, a label sticking device 1 includes a cylindrical sticking drum 3 provided on a support frame 2 and rotated clockwise in a horizontal plane. The sticking drum 3 is rotatably driven by a driving means (not shown) in synchronism with a carrying device for carrying the container. The sticking drum 3 has a large number of suction ports (not shown) opened on the outer peripheral surface thereof, and the label can be sucked and conveyed by these suction ports. In the illustrated embodiment, the position above the sticking drum 3 in FIG. 1 is the label sticking position A, and at this sticking position A, the labels are sequentially stuck to the containers conveyed by the conveying device (not shown). ing.

A supply means 5 for supplying a label to the sticking drum 3 is provided at the lower right position of the sticking drum 3. The supply means 5 is equipped with a feed roller 6 for pulling out the roll label L wound on a reel (not shown), and the leading end of the roll label L fed from the feed roller 6 is cut by a cutter 7 to a predetermined length. It is supposed to be done. Then, the label cut by the cutter 7 to a predetermined length is attracted by the delivery roller 8 on its adhesive surface side and rotated counterclockwise, and then at the supply position B, the adhesive surface side is placed on the outside. It is supplied to the drum 3. The delivery roller 8 is formed in a columnar shape, and a large number of suction ports (not shown) are provided on the outer peripheral surface thereof similarly to the sticking drum 3, and the label cut by the cutter 7 is used by the suction port. After sucking and conveying to the supply position B, the suction is stopped at the supply position B and the label is delivered to the sticking drum 3.

On the outer periphery of the pasting drum 3, blow-out ports 11 and 12 of heating means 10 for blowing hot air are provided to each other over a range from a position beyond the supply position B to a position before the pasting position A. The label is adhered to the adhesive surface of the label by blowing hot hot air blown from the outlets 11 and 12 onto the adhesive surface of the label sucked on the outer peripheral surface of the sticking drum 3. The agent can be activated.

By the way, in the above label sticking apparatus 1, the sticking drum 3 is heated to a high temperature by the heating means 10.
And the delivery roller 8 are disposed adjacent to each other, and the delivery roller 8 and the outlet 11 of the heating means 10 are disposed adjacent to each other, so that the delivery roller 8 is gradually heated. Then, the delivery roller 8 adsorbs the adhesive side of the label and conveys it.
There is a drawback that the label is adhered to the delivery roller 8. Further, when the delivery roller 8 reaches a high temperature, the cutter 7 placed adjacent to the delivery roller 8
Will gradually be heated. Then, since the adhesive of the label adheres to the blade of the cutter 7, there is a drawback that the label cannot be cut reliably. Therefore, in this embodiment, the partition plate 15 is provided between the delivery roller 8 and the heating means 10, and cold air is blown to the delivery roller 8 side of the partition plate 15 to blow the partition plate 15. A cooling means 16 for cooling is provided.
The partition plate 15 includes a pair of plate members 17 and 18 arranged in parallel with a predetermined gap therebetween, and a heat insulating material 19 attached to the plate member 17 provided on the outlet 11 side. Polycarbonate or aluminum can be used as the plate members 17 and 18, and Gore-Tex (trade name) is used as the heat insulating material 19.
Can be used. Further, as shown in FIGS. 1 and 2, the end of the partition plate 15 on the side of the sticking drum 3 is brought close to the sticking drum 3, and the lower part is extended downward so as not to interfere with the sticking drum 3. It is arranged between the delivery roller 8 and the heating means 10. As shown in FIG. 2, a pipe 21 is arranged between the pair of plate members 17 and 18, and cooling water is circulated in the pipe 21 to cool the plate members 17 and 18. There is. Further, the cooling means 16 is provided with an air blowing nozzle 20 for injecting cold air toward the delivery roller 8, and the air blowing nozzle 20 communicates with a compressed air source via a pipe (not shown). Although the cooling means 16 blows air at room temperature onto the delivery roller 8 as cold air, it goes without saying that a heat exchanger for cooling the air may be provided in the pipe.

According to the label sticking apparatus 1 having the above-mentioned structure, the roll label L wound around the reel (not shown)
Is pulled out by the feed roller 6 and cut into a predetermined length by the cutter 7, and then the adhesive surface side is sucked by the delivery roller 8 and conveyed counterclockwise. Then, the label is supplied to the sticking drum 3 with the adhesive surface side facing outward at the supply position B, and while being conveyed by the sticking drum 3, the outlets 11, 1 of the heating means 10 are provided.
The hot hot air blown from 2 activates the adhesive of the label. Further, at the sticking position A, the sticker is stuck to a container conveyed by a conveying device (not shown).

During this time, the delivery roller 8 is heated by the high-temperature hot air blown from the blow-out ports 11 and 12, but the cold air from the blower nozzle 20 is blown to the delivery roller 8, so that the delivery is performed. The heating of the roller 8 is suppressed. In addition to this, since the partition plate 15 is arranged between the delivery roller 8 and the outlet 11 of the heating means 10, the heat of the outlet 11 is prevented from being radiated to the delivery roller 8, and At the same time, the cold air from the blower nozzle 20 prevents hot air from the outlet 11 from flowing over the partition plate 15 to the delivery roller 8 side. In this way, the cold air from the partition plate 15 and the blowing nozzle 20 effectively cools the delivery roller 8 and prevents the adhesive of the label carried by the delivery roller 8 from being activated. The delivery roller 8
The label can be reliably supplied to the sticking drum 3. When the heating of the delivery roller 8 can be prevented, the heating of the cutter 7 that has been heated by the delivery roller 8 can also be prevented, and therefore the cutter 7 can be prevented.
It is possible to prevent the label adhesive from adhering to the blade of and to cut the label surely.

Although the present invention is applied to a roll labeler in the above embodiment, it is needless to say that the present invention can be applied to a single-wafer labeler.

[0013]

As described above, according to the present invention, it is possible to effectively cool the delivery roller that conveys the label with the adhesive surface facing inward, so that the label can be attached to the delivery roller. Since it is possible to prevent the label adhesive from remaining on the delivery roller, it is possible to reliably supply the label from the delivery roller to the application drum. Further, in the present invention, since it is possible to prevent the cutter adjacent to the delivery roller from being heated, it is possible to prevent the adhesive of the label from adhering to the blade of the cutter, and to reliably cut the label. The effect is obtained.
