[Prior Art]

 Conventionally, an automatic labeling device has been proposed in which an article conveyed to a conveyance mechanism is conveyed to a predetermined label attaching position, and the label attaching mechanism attaches the label from above the stopped article to the position. Has been widely used. However, with the conventional structure, although there is no inconvenience if the outer surface of the article to which the label is attached is flat, an article having a curved outer surface, particularly a cylindrical or cylindrical shape, is used. In the case of the above item, the label pressing force required for applying the label does not act evenly on the applying surface, so the adhesive strength of the adhesive applied to the back side of the label decreases, and the adhesive from the edge of the label is often used. There was a fear that peeling would occur.

Therefore, in order to solve the above point, it has been proposed to rotate the conveyed article at the label attaching position and apply the label pressing force along the curved surface of the article. This product complicates the interlocking connection between the transport mechanism and the rotating structure that rotates the article at the label sticking position, which not only inevitably reduces the label sticking accuracy and sticking efficiency, but also enlarges the entire device. It had the drawback of increasing the manufacturing cost.

【Example】

 The configuration of the present invention will be described in detail with reference to an embodiment shown in the drawings. In FIG. 1 and FIG. 2, reference numeral 1 denotes an automatic labeling device, which comprises a transport mechanism 3 in which the transport bodies 2a and 2b are wound around an article placing portion 2c and a label sticking mechanism 4. And a main body 5 provided. On the main body 5, a strip-shaped mount 6a formed by continuously sticking labels 6, 6 ... Is drawn out and wound around a reel 7. The mount 6a includes a guide roller 8a, a drive roller 8 and a pressure contact roller. 9 and 9, the label peeling edge 10 is fed out, and the mount 6a after the label peeling is wound around the take-up reel 11.

The carrying mechanism 3 is provided with an article placing portion 2c having a curved concave portion 2d on the carrying end side of the carrying body 2a, and the carrying body 2b is provided on the carrying-out side of the article placing section 2c via an inclined surface. The transport start end sides of the push-up bodies 12 are arranged close to each other, and a push-up body 12 is vertically erected vertically below the article placing portion 2c.

On the other hand, in the label sticking mechanism 4, the first rod 15 and the second rod 16, the first hydraulic cylinder 17 and the first hydraulic cylinder 17 and the first rod 15 are provided on the arms 13 and 14 provided in parallel on the one side of the base body 4a so as to project vertically. The two hydraulic cylinders 18 are erected parallel to each other with a distance of the center distance L, and the tips of the protruding and retracting rods of the hydraulic cylinders 17 and 18 are connected to the first rod 15 via the connecting blocks 19 and 19, respectively. The second rod 16 and the second rod 16 are interlocked with each other. The label suction portion 20 is attached to the lower end of the first rod 15 with the suction surface 20a facing downward, and the lower end of the second rod 16 is made of a synthetic resin elastic cushion material. A label pressing portion 21 is attached via a support plate 22, and a triangular void portion 23 is formed in a central portion of the attachment side of the support plate 22 facing the pressing surface 21a of the label pressing portion 21. Is cut out.

The base body 4 a of the label sticking mechanism 4 is horizontally movably mounted on cylinder mechanisms 24, 24 arranged in parallel vertically on the main body 5 side. The label sticking mechanism 4 is configured to horizontally move to the side of the carrier 2a in association with the intermittent transport of the columnar articles 25, 25 ... Reference numeral 26 is a mounting plate for attaching the automatic labeling device 1 to the frame 27, and 28 is a main driving device of the automatic labeling device 1.

In the above structure, when the articles 25, 25, ... Are conveyed by the conveyor 2a from the not-shown pre-process to the conveyance end side, the articles 25 roll on the article placing portion 2c one by one to form curved concave portions. Fit in 2d. At this time, as shown in FIGS. 3 and 4, the mount 6a is wound in the direction of the arrow A by the rotational drive of the take-up reel 11 by a control signal (not shown), and only one label 6 is peeled off from the label 6 on the mount 6a. It is peeled off by the edge 10 and adsorbed on the adsorption surface 20a of the label adsorption portion 20. Next, in the state where the label 6 is adsorbed on the label adsorbing section 20, a drive signal (not shown) is transmitted to the cylinder mechanisms 24, 24, and the telescopic rods 24a, 24a of the cylinder mechanisms 24, 24 are moved by the distance L in the direction of arrow B. The label sticking mechanism 4 horizontally moves and the first rod 15 moves right above the article 25 fitted in the curved concave portion 2d. (Fig. 5)

Next, as shown in FIG. 6, as the first hydraulic cylinder 17 is moved downward by an unillustrated descending signal, the suction surface 20 a of the label suction portion 20 contacts the top of the article 25 until the suction surface 20 a contacts the top of the article 25. The first rod 15 descends, the label 25 is temporarily attached to the top of the article 25, the label adsorption of the label adsorption unit 20 is released, and the first rod 15 rises and returns to the stop position. The retractable rods 24a, 24a of the connector 24, 24 are retracted to the main body 5 side by a drive signal (not shown), and the initial state of FIG.

Then, from the initial state of FIG. 1, the second hydraulic cylinder 18 is moved downward by a not-shown descending signal, and the second rod 16 starts descending. At this time, as shown in FIGS. 7 (a) to 7 (c), the label pressing portion 21 attached to the tip of the second rod 16 has the pressing surface 21a from above the temporarily attached label, and the pressing surface 21a is attached to the article 25. However, since the void 23 formed in the notch in the label pressing portion 21 shrinks as the pressing operation progresses, the pressing force applied to the article 25 does not act strongly only on the article and the top. The pressing force of the label pressing portion 21 acts uniformly on the attaching surface area of the label 6, and the label 6 is reliably attached to the article 25 without inducing peeling at the label end portion. (Figure 8)

After that, when the second hydraulic cylinder 18 is moved upward by a lift signal (not shown) and the second rod 16 is returned to the initial state of FIG. 1, as shown in FIGS. 9 (a) and 9 (b), The push-up body 12 moves upward from below the placing portion 2c, and the article 25 to which the label 6 is attached is rotated in the direction of arrow C by being guided by the push-up surface 12a obliquely provided at the upper end of the push-up body 12. The article 25 is transferred to the start side of the transfer of the transfer body 2b through the inclined surface of the transfer mechanism 3, and the article 25 is transferred to the next step.

Therefore, the labels 6, 6 ... Can be attached to the outer peripheral surfaces of the cylindrical articles 25, 25 ... Smoothly and reliably, and the efficiency of the label attaching work can be improved. Further, since the label pressing portion 21 is deformed corresponding to the outer peripheral surface of the article 25 to which the label 6 is attached, the same label pressing portion 21 can be used to flexibly cope with various columnar articles having different diameters. You can
