FIG. 7 is a schematic diagram showing the relationship between the state of the suction rotary drum stopped because the adhesive tape is cut by the cutter and the position of the article conveyed on the conveyor. FIG. FIG. 9 is a schematic view showing a state in which the suction holding by the suction rotary drum is released from the state of FIG. 8 and the cut label, which is the adhesive tape, is attached to the article conveyed on the conveyor, and FIG. It is a schematic diagram which shows the state which the label was affixed to the article conveyed on the conveyor from. The operation of attaching the label to the surface of the article will be described below.

The suction rotary drum 17 is stopped at a position where the cutter 45 and the cutter groove 23a face each other as shown in FIG. In this stopped state, the cutter 45 rotates to pass through the cutter groove 23a, and the suction rotary drum 17
The adhesive tape 5 having the non-adhesive surface 5b side adsorbed and held on the side surface 19 thereof is cut into a label 59. The non-adhesive surface 5b side of the label 59 is suction-held on the side surface 19 of the suction rotary drum 17 by the suction force of the air suction holes 21h and 21i. Further, on the side surface 19 of the suction rotary drum 17, the label 61 is also suction-held on the non-bonding surface 5b side by the suction force of the air suction holes 21e and 21f.

By the time the suction rotary drum 17 is stopped, the pull-out roll 15 pulls out the adhesive tape 5 by a certain length, and then the pull-out roll 15 stops and the adhesive tape 5 continues to rotate. The non-adhesive surface 5b side is adsorbed and slipped on the side surface 19 of the adsorbing rotary drum 17.

When the article 55 conveyed on the conveyor 53 reaches the position shown by the broken line in the stopped state of the suction rotary drum 17, the suction rotary drum 17 as an example of the adhesive tape moving means rotates. To start.

Next, the rotation speed of the suction rotary drum 17 increases, the speed at which the article 55 is conveyed by the conveyor 53, and the side surface of the suction rotary drum 17 rotates so that the conveyor 55 conveys the article 55. When the speed in the tangential direction passing through the facing position 60 facing the sticking position 58 becomes the same, the suction rotary drum maintains the constant speed rotation.

With the speeds thus synchronized,
The timing design is such that the leading edge 61a of the label 61 reaches the facing position 60 after the leading edge 55a of the article 55 conveyed by the conveyor 53 passes through the attaching position 58.

The communication between the intake passage 22e connected to e and the air intake passage 29 formed in the fixed drum 27 is cut off, and the air suction hole 21e is formed.
The suction force due to is stopped and the release of suction holding of the label 61 is started. After the suction force is stopped, the intake passage 22e connected to the air suction hole 21e communicates with the air outlet passage 31 formed in the fixed drum 27. The air suction hole 21e serves as an air blowing hole for blowing air, and the label 61 is pushed toward the upper surface of the article 55 by the blown air.

Has been done. In particular, the pushing means is composed of an air blowing mechanism capable of blowing from the air blowing hole.

Similarly, the suction holding force by the air suction holes 21f is stopped, and the air suction holes 21f are pushed out after the air suction holes 21f are changed to the air blow holes, so that both the air suction holes 21e and 21f for sucking and holding the label 61 are removed. The suction holding force is released, and the label 61 is attached to the upper surface of the article 55 as shown in FIG.

Thus, the reciprocating movement of the suction block for sticking as in the conventional adhesive tape sticking machine shown in FIG. 15 is not performed, and the sticking time per one time is shortened accordingly. It becomes possible to attach the cut adhesive tape to an article that is an object that is continuously conveyed at high speed by a conveying means such as a conveyor. Further, the sticking to the article is not limited to the corner on the front side of the article as in the conventional adhesive tape sticking machine shown in FIG. 16, but the sticking to the upper surface is possible.

Further, the cut adhesive tape is applied with a pushing force other than gravity after the suction holding force is stopped, so that the adhesive tape can be reliably attached to the upper surface.

Further, since the suction holding force of the cut adhesive tape is released in order from the front side, the cut adhesive tape is not held on the suction rotary drum and the article is released as compared with the case where they are released all at once. The floating time that is not attached to can be shortened. Therefore, from this point as well, it is possible to surely adhere to the upper surface.

1 to 6, the scraper 54 provided on the downstream side of the attaching position 58 (opposing position 60) has the ring-shaped grooves 25a, 2a of the suction rotary drum 17.
It has a portion that fits within 5b. Therefore, the suction rotary drum 17 is also provided on the downstream side of the facing position 60.
The label that is still held on the side surface of the label is collided and forcibly peeled off because the scraper 54 has the above-mentioned portion accommodated in the ring-shaped grooves 25a and 25b. As a result, the suction rotary drum 17 rotates while the label is held, and the adhesive tape 5 pulled out from the pull-out roll 15 is
The suction rotary drum 1 from the top of the retained label
The problem of overlapping and adhering to the side surface 19 of 7 will be prevented in advance.

As described above, the suction rotary drum 17 which has gone through the rotation state of FIGS. 8 and 9 from the stopped state of FIG. 7 rotates until the cutter groove 23b is positioned at the position of the cutter groove 23a of FIG. Continue to stop the cutter 45
