Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking apparatus mainly used for a strip coil and a sheet material packing line.

[0002]

2. Description of the Related Art Conventionally, a strip coil (hereinafter simply referred to as "coil") generally packaged has a print label, a print label or the like attached to a predetermined position by hand.
Also, when sticking by machine, 1 for each type of label
A plurality of mechanical devices were required because the coils were attached to the outer surface, the inner surface, and the rear surface of the coil using a single attachment device.

[0003]

Among the conventional sticking methods, the manual sticking has a problem such as a wrong label, a wrong sticking position, or a misalignment. Further, even in the case of a machine, it can be handled only by each dedicated device for outer surface, inner surface, and side sticking, which requires a large installation space and has a problem that the mechanism is complicated. .. The present invention has been made in view of the above problems of the conventional technology, and an object of the present invention is to have a simple structure and minimize the installation space, and yet a wide variety of labels. The present invention is intended to provide a label sticking device capable of sticking a label to a predetermined position without fail.

[0004]

In order to achieve the above object, a label sticking apparatus of the present invention comprises a label printer and a printing label peeling machine for feeding a label to a label receiving stand, and a belt for receiving the label to a predetermined position. The label holder that slides to a specific position of the robot operation with the cylinder after moving with, and the suction pad that adsorbs the label from the label holder and tilts it to the predetermined position of the coil according to the shape of the coil and deforms and attaches it. It consists of a robot attached to the end of the arm.

[0005]

The label sticking apparatus configured as described above supplies the desired label to the label holder after peeling the desired label with the label printer and the label after the printer with the printing label peeling machine,
When the label is moved to the predetermined position on the label receiving stand by the belt and the positioning sensor, then the cylinder moves the label receiving stand to the robot label adsorption position, and the label receiving stand is stopped at the predetermined position by the positioning sensor. Move the robot arm to stop the suction pad just above the label placed on the label holder and turn on the suction pad vacuum device. On the label holder side, compressed air is supplied from below the label to the nozzle. Since the label paste adheres to and deposits on the surface of the belt as it blows out and interferes with label adsorption, a powder application pad for applying powder is provided to surely adsorb the label to the adsorption pad. The powder may be Teflon powder, siccalol, or water.

When the label suction is completed and the sensor confirms this, the robot arm is moved to the sticking position according to the upper data to move the suction pad and stop at a position about 30 mm above the sticking position of the packing coil. After that, the sticking surface of the pad is pressed against the sticking surface of the coil with the sticking air cylinder, and the inclination between the sticking surface of the coil and the sticking surface of the pad is corrected by sliding the pad guide shaft.
In addition, the coil is firmly attached to the sticking surface because the suction surface of the pad, which is bulged in a U shape at the center with a rubber material, is appropriately deformed according to the shape of the coil sticking surface and pressed from the center of the label. You can prevent the occurrence and attach the label securely.
After pressing for a certain period of time, move to the position of the next label holder to adsorb the next label, repeat the above series of operations, and confirm that all the necessary labels have been adsorbed and attached. Return to the origin.
