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 abbreviated as "coil") which is generally packaged has a print label, a print label, and the like affixed to a predetermined position manually.
Also, when sticking with a machine, 1
Since the coil was attached to the outer surface, the inner surface, and the rear surface of the coil by using one attaching device, a plurality of mechanical devices were required.

[0003]

Among the conventional sticking methods, if the sticking method is manually performed, there are problems such as a wrong label, a wrong sticking position, or a misalignment. Further, even in the case of using a machine, it is possible to cope only with the dedicated devices on the outer surface, the inner surface, and the side surface, which requires a large installation space and has a problem that the mechanism is complicated. . SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the related art, and has as its object to simplify the structure, to minimize the installation space, and to provide a wide variety of labels. Is intended to provide a label sticking apparatus capable of sticking a label to a predetermined position without fail.

[0004]

In order to achieve the above object, a label sticking apparatus according to the present invention comprises a label printer for supplying a label to a label receiving table, a printing label peeling machine, a belt for receiving the label and a belt to a predetermined position. The label receiving tray that slides to the specific position where the robot is operated after moving with the cylinder, and the suction pad that sucks the label from the label receiving tray and tilts to the predetermined position of the coil according to the shape of the coil, and deforms and adheres It consists of a robot attached to the tip of the arm.

[0005]

The label sticking apparatus configured as described above supplies a desired label to a label receiving table after peeling off a desired label by a label printer and a printed label peeling machine,
When the label is moved to the predetermined position on the label receiver by the belt and the positioning sensor, then the label receiver is moved to the label suction position of the robot by the cylinder, and the label receiver is stopped at the predetermined position by the positioning sensor. Move the arm of the robot to stop the suction pad immediately above the label placed on the label receiver, turn on the suction pad vacuum device, and press the compressed air from the nozzle below the label on the label receiver side from the nozzle. Since the label paste adheres and accumulates on the surface of the belt at the same time as blowing out to prevent label adsorption, a powder application pad for applying powder is provided to reliably adsorb the label to the adsorption pad. The powder may be Teflon powder, sickerol, or water.

When the sensor confirms this when the label suction is completed, the robot arm is moved to the sticking position according to the upper data to move the suction pad, and stops at a position about 30 mm above the position where the packing coil is stuck. , After that, press the suction surface of the pad against the bonding surface of the coil with the air cylinder for bonding, and correct the inclination between the bonding surface of the coil and the suction surface of the pad by sliding the pad guide shaft, etc.
In addition, to ensure that the coil adheres firmly to the surface where the coil is attached, the suction surface of the pad, whose center is swelled in a U-shape with rubber material, is appropriately deformed according to the shape of the coil application surface and pressed against the center of the label. Labels can be securely attached to prevent occurrence.
After pressing for a certain period of time, move to the position of the next label receiving tray to adsorb the next label, repeat the series of operations, and confirm that all necessary labels have been adsorbed and affixed. Return to the origin.

[0007]

Embodiments will be described with reference to the drawings.
1 to 3, the printer 1 employs, for example, a thermal transfer barcode printer, and fixes a label sending port toward the slide rail 2 at a position outside one end of the slide rails 2 and 2 laid in parallel. The printed label peeling device 3 is arranged side by side with the printer 1, and fixes the delivery port of the peeled label toward the slide rail 2 side.

Further, the printing label peeling device 3 will be described in more detail. A known printing label peeling device may be used. For example, in FIG. A label peeling doctor 6 is provided at an oblique front position of the prevention roller 5, a backing paper 7 with a label is wound around the supply reel 4, the backing paper is passed through the slack prevention roller 5, and the label 8 peeled off by the label peeling doctor 6.

After the label is peeled off, the backing paper is held between a driving roller 9 for feeding the backing paper and a holding roller 11 of a slip prevention lever 10 provided with a tension spring, and wound on a take-up reel 12.

The label receiving trays 13 and 13 rotate in a direction perpendicular to the slide rail 2 at a position substantially equal to the height of the label sent from the label sending port of the printer 1 and the printing label peeling device. It is formed by a label transport conveyor 14 formed by a plurality of round belts, a label positioning sensor 15 provided below the label transport conveyor 14, and an air jet nozzle 16 for assisting label adsorption described later. More specifically, the label transport conveyor 14 of the label receiving table 13 rotates the drive pulley 19 via the timing belt 18 by the pulse motor 17, and the drive pulley 19 and the driven pulley 2
A plurality of round belts are wound around zero to form a label transport conveyor 14, and the label transport conveyor 14 is operated in synchronization with the feed speed of the printer 1 or the print label peeling device 3.

The label receiving tables 13, 13 are provided on a slide base plate 21, and a slide unit 22, which slides loosely on the slide rail 2, is fixed to the lower surface of the slide base plate 21, and the slide base plate is further provided. A printer 1 or a printed label peeling device is mounted on the lower surface of the printer 1 by moving a label receiving table 13 in the left-right direction by engaging a moving table 24 of a rodless cylinder 23 provided in a parallel direction between the slide rails 2 and 2. 3 and, to be described later, between the label receiving positions of the robot.

5 to 7, the sticking air cylinder 25 is attached to the tip of an arm 27 of a robot 26. It is desirable that the robot 26 be of a vertical articulated type, for example. Is provided within an arm operating range in which the label 8 in a state where the label receiving table 13 has stopped moving can be adsorbed and attached to the coil C (see FIG. 1) on the transport conveyor. The pad support plate 28 is formed of, for example, a longitudinally grooved iron material, and one end of the pad support plate 28 is fixed to the rod 29 of the sticking air cylinder 25. Each of the slide bearings 30, 30,...
Are perforated, and the support surface 31 is provided in the support surface 31.
A pad guide shaft 33 having a tapered fitting surface 32 provided on the head portion, which fits in the lower portion, is loosely fitted by penetrating the pad support plate 28 in the lower half.

The top plate 35 of the pad 34 is fixed to the lower ends of the pad guide shafts 33. Coil spring 36
Is wound around the pad guide shaft 33 and is provided between the pad support plate 28 and the top plate 35, so that the top plate 35 is always kept away from the pad support plate 28 (downward in FIG. 5).
Press The label suction surface 37 is formed by bending a flexible and resilient rubber plate, for example, into a U-shape in vertical section.
To the left and right side surfaces 38 to form a cavity 39 inside. Reference numerals 40, 40 ... denote air suction holes formed in the label suction surface 37.

Reference numerals 41, 41 denote hanging lid surfaces which are hung on front and rear end surfaces of the label suction surface 37, and are preferably formed of rubber material. The duct 42 is mounted in communication with a vent hole 43 formed in the top plate 35, and is connected to a known vacuum device (not shown) at the other end.
