[Industrial applications]

 The present invention relates to an automatic labeling device for attaching a label with a trademark, a price, a manufacturing date, etc. to an article on a mounting table, and particularly to an article having an outer surface formed into a curved surface. The present invention relates to an automatic labeling device that can be applied smoothly and reliably.

[0002]

[Prior art]

 Conventionally, an automatic labeling device has been proposed, which is configured to convey an article conveyed to a conveyance mechanism to a predetermined labeling position and to apply a label from above the stopped article at the position by the labeling mechanism. Has been done. However, with the conventional structure, if the outer surface of the article to which the label is attached has a flat surface, no problem occurs, but an article having an outer surface formed of a curved surface, particularly a cylindrical or cylindrical shape In the case of the above item, the label pressing force required for applying the label does not act evenly on the attaching surface, so the adhesive strength of the adhesive applied to the back side of the label decreases, and often the label end There was a fear that peeling would occur.

Therefore, in order to solve the above-mentioned point, the present applicant can reliably attach the label to the outer peripheral surface formed by the curved surface of the article without requiring a complicated article rotation mechanism in advance. We have proposed an automatic labeling device that can be applied to a wide range of products with different diameters, and that can improve the sticking operation efficiency while maintaining the sticking accuracy of labels. However, when the above-mentioned proposed automatic labeling device is applied to so-called semi-automatic high-mix low-volume production in which an operator manually supplies and removes articles to and from the mounting table, Since a series of work processes such as placing items → labeling with an automatic labeling device → taking out items are configured, the automatic labeling device can be stopped during the downtime due to individual differences in workers who supply and take out items. There are long and short variations, and there is a limit to improving the efficiency of stable labeling operation. Therefore, not only increasing the repetition speed of the labeling operation of the automatic labeling device will increase the burden on the operator, but also the labeling mechanism. Since an article is placed below the rod of the operator, a worker can get his hands caught between the label sticking mechanism and the placing table due to an erroneous operation. Included are we doing was the actual situation.

[0004]

[Problems to be solved by the present invention]

 The present invention was created in the research and development process for the purpose of efficiently labeling a product having an outer surface formed of a curved surface as described above, and its purpose is semi-automatic. Even in high-mix low-volume production, the efficiency of labeling can be improved as much as possible while maintaining the burden on workers and improving safety, and the range of application of the automatic labeling device can be expanded. It aims to provide an automatic labeling device.

[0005]

[Means for Solving the Problems]

 In order to solve the problem, the technical means adopted by the present invention is a first rod having a label suction portion at the lower end above a mounting table on which an article having an outer surface formed of a curved surface is horizontally mounted. And a second rod having a label pressing portion attached to the lower end thereof are arranged side by side so as to be vertically retractable, and a plurality of articles are placed on the placing table at predetermined intervals. In addition to arranging the parts horizontally, the mounting table is formed so as to be slidable in the horizontal direction, and linked to the sticking operation of the label sticking mechanism so that each article mount part is connected to the first rod and the second rod. It is characterized in that it is configured to switch and move to the drooping position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described in detail with reference to one embodiment shown in the drawings. 1 to 3, reference numeral 1 denotes an automatic labeling device, which is provided with a placing table 3 having article placing portions 2a and 2b at predetermined intervals, and a label attaching mechanism 4. And a main body 5. The main body 5 is provided with a strip-shaped mount 6a formed by continuously applying labels 6, 6 ... And wound around a reel 7. The mount 6a is guided by guide rollers 8 and 9 to a label peeling edge. While being fed to 10, the mount 6a after peeling the label is wound around the winding reel 11.

The label attaching mechanism 4 vertically extends the first rod 12 and the second rod 13 of a hydraulic cylinder (not shown) incorporated in the base body 4a so as to be capable of protruding and retracting in parallel at a distance of the center distance L1. At the same time, a label suction portion 14 with the suction surface 14a facing downward is attached to the lower end of the first rod 12, and a label pressing member made of a synthetic resin elastic cushion material is attached to the lower end of the second rod 13. The portion 15 is attached via a support plate 16, and a triangular void portion 17 is formed in a notch at a central portion of the attachment side of the support plate 16 facing the pressing surface 15a of the label pressing portion 15. Has been done.

The base body 4 a of the label attaching mechanism 4 is horizontally movably mounted on cylinder mechanisms 18, 18 arranged in parallel vertically on the main body 5 side, and has a cylindrical shape on the mounting table 3. Are connected to the placement of the articles 19, 19 ... Formed in the above, and the hanging positions of the rods of the label sticking mechanism 4 are configured to move in parallel in the horizontal direction by the center distance L1.

On the other hand, in the mounting table 3, the article mounting portions 2a and 2b having the recesses 20 and 20 formed on the upper surface are arranged on the substrate 3a, and the lower surface of the substrate 3a is attached to the tip of the retractable rod 21 of the hydraulic cylinder (not shown). Is formed so that the substrate 3a slides in the horizontal direction by the center distance L2 between the recesses 20 and 20, and the drive roller 22 faces the inside of the recesses 20 and 20. And driven rollers 23, 23 are rotatably supported, and the drive rollers 22 are driven by the drive motors 24, 24 disposed on the lower surface of the substrate 3a via the pulley 25 and the belt 26, and the article placing portions 2a, 2b are placed. The upper articles 19, 19 are configured to rotate.

Further, auxiliary rods 28 and 28, which axially support the copying rollers 27 and 27 at the tips thereof, are provided opposite to each other at positions facing the upper surfaces of the articles 19 and 19 on the article mounting portions 2a and 2b. The drive rollers 24, 24 are linked to the rotational drive of the drive motors 24, 24 to press the copying rollers 27, 27 against the outer peripheral surfaces of the articles 19, 19. Reference numeral 29 is a rotary handle for finely adjusting the amount of horizontal movement of the base body 4a, 30 is a main motor of the label sticking mechanism, 31 is a control panel for controlling the number of sticking labels, sticking speed, etc., and 32a and 32b are respectively activated. A switch and a stop switch 33 are sensors that detect the presence or absence of the article 19.

In the above-mentioned configuration, first, the articles 19 and 19 are placed on the article placing sections 2a and 2b of the placing table 3, respectively, and the activation switch 32a is turned on to start the automatic labeling device. At this time, a control signal (not shown) is sent to wind the mount 6a by the rotational drive of the take-up reel 11, and only one label 6 on the mount 6a is peeled off by the label peeling edge 10 and the label adsorbing portion 14 moves. It is adsorbed on the adsorption surface 14a. Next, a drive signal (not shown) is transmitted to the cylinder mechanisms 18 and 18 in a state where the label 6 is attracted to the label attracting portion 14, and the extension of the cylinder mechanisms 18 and 18 causes the base body 4a to move horizontally in the direction of arrow A by a distance L1. The first rod 12 of the label sticking mechanism 4 moves right above the article 19 fitted in the recess 20 of the article placing section 2a.

Then, the first rod 12 descends until the suction surface 14a of the label suction portion 14 comes into contact with the top of the article 19 by a descent signal (not shown), and the label 6 is temporarily attached to the top of the article 19 and the label suction is performed. After the label suction of the portion 14 is released and the first rod 12 is raised and returned to the stop position, the base body 4a is returned to the initial state by the retracting operation of the cylinder mechanisms 18 and 18.

Thereafter, as shown in FIG. 4, the descending signal (not shown) starts the descending of the second rod 13, and the pressing surface 15a of the label pressing portion 15 attached to the tip of the second rod 13 is pressed. At the time of the interview, the temporarily attached label 6 comes into close contact with the outer peripheral surface of the article 19 from above, and at the same time, the drive motor 24 is driven so that the article 19 rotates in the recess 20 and is attached to the auxiliary rods 28, 28. The label 6 is pressed against the outer peripheral surface of the article 19 by the copying rollers 27, 27, and the label 6 is surely attached to the article 19 without inducing peeling at the label end portion.

When the sticking of the label on the side of the article placing section 2a is completed, the second rod 13 is returned to the initial state by an ascending signal (not shown), and the retractable rod 21 is retracted to cause the placing table 3 to move. The article 19 fitted in the concave portion 20 of the article placing portion 2b moves horizontally in the direction of the arrow B by the distance L2, and moves vertically below the second rod 13. Then, the label sticking operation similar to that of the article 19 of the article placing section 2a is performed.

During the operation of applying the label 6 to the articles 19 and 19 as described above, while the label application is being performed on one of the article placement sections 2a or 2b, the operator can place the label on the other article. The article 19 to which the label 6 is to be attached next can be placed in advance on the placing section, and the article 19 that has completed the label attachment can be taken out when the operation of attaching to the other article placing section is started. Therefore, the label sticking operation and the supply and removal of the article 19 can be performed at the same time, and the label sticking efficiency can be improved in the semi-automatic multi-product small-volume production.

Further, as shown in FIG. 5, the article mounting portions 2 a and 2 b and the auxiliary rod 28 which axially supports the copying roller 27 are appropriately replaced in correspondence with the diameter of the article 19 to thereby achieve the same automatic labeling. It is possible to flexibly deal with various columnar articles having different diameters by using the device 1.
