Hereinafter, in the horizontal plane, the same direction as the feeding direction of the label 3 will be referred to as the X direction, and the direction orthogonal thereto will be referred to as the Y direction.

The label positioning device 40 comprises a suction head 4
5, sticking cylinder 46, X-direction positioning cylinder 4
7, a Y-direction positioning cylinder 48, X-direction positioning reference guides 51, 52, 53, and a Y-direction positioning sensor 55. The suction head 45 has a box shape elongated in the Y direction, and is provided near the tip of the edge member 43. The suction head 45 has a smooth suction surface 45a in the horizontal direction, and sucks the label 3 fed from the tip of the edge member 43 and holds the label 3 in the horizontal direction. Although not shown, the suction head 45 is connected to a suction blower via, for example, an elastic pipe, and a large number of minute suction openings are formed on the suction surface 45a.

The suction head 45 has three notches 45b on the long side face away from the edge member 43 so that the edges 3a and 3b of the label 3 in a developed state sucked on the suction surface 45a partially protrude. , 45c, 45d, and also has one notch 45e on the short side face that is perpendicular to the long side face. In addition, the suction surface 45a is formed with a concave portion 45f having a size sufficient to accommodate the raised portion 10 at a portion corresponding to the raised portion 10 of the unit body 2, and the other portion of the suction surface 45a is raised. The suction head 45 can be sufficiently lowered to a position where the label 3 sucked on the suction surface 45a comes into contact with and is attached to the front surface of the unit body 2 without contacting the suction head 45.

The sticking cylinder 46 is for sticking the label 3 on the front surface of the front cover 5 of the unit body 2 positioned below, and its movable portion is fixed to the central portion of the upper portion of the suction head 45. The suction head 45 is moved up and down. The movable portion of the X-direction positioning cylinder 47 is fixed to the side surface of the sticking cylinder 46, and the suction head 45 is moved in the X direction together with the sticking cylinder 46. The movable portion of the Y-direction positioning cylinder 48 is fixed to the X-direction positioning cylinder 47, and the suction head 4 is attached.
Cylinder for attaching 5 and positioning cylinder 47 for X direction
Move in the Y direction.

Near the suction head 45 in the X direction, a long side edge 3a of the label 3 is brought into contact with the suction head 45 to position the label 3 in the X direction.
The individual reference guides 51, 52, 53 are installed in a straight line in the Y direction. In the vicinity of the suction head 45 in the Y direction, for example, a reflective Y-direction positioning sensor 55 that detects the edge 3b of the short side of the label 3 is installed. The edge detection signal from the Y-direction positioning sensor 55 is input to the computer 56, which controls the driving of the Y-direction positioning cylinder 48. A belt conveyor 61 that conveys the unit main body 2 to the label supply station 39 is installed below the label supply station 39 (see FIG. 4), and jigs 62a and 62b for holding the unit main body 2 from both sides. Is fixed.

The operation of the label positioning device 40 thus constructed will be described. When the unit main body 2 assembled on another assembly line is conveyed to the end of the belt conveyor 61, it is fixed to the jigs 62a and 62b by a robot arm installed near the end of the belt conveyor 61. When the belt conveyor 61 is driven and the unit main body 2 arrives at the label supply station 39, the take-up roller 44 winds the release paper 42 for a certain length, and one label 3 is fed out in a substantially horizontal direction. At this time, X
The movable portion of the directional positioning cylinder 47 is extended, and as shown in advance by the chain double-dashed line in FIG.
Has been moved to the vicinity of the tip of the edge member 43.

The label 3 is the suction surface 45a of the suction head 45.
When the label 3 is fed downward, the feeding position of the label 3 is detected by a sensor switch or the like (not shown), the driving of the suction head 45 is started, and the label 3 is sucked onto the suction surface 45a. At this time, the edge 3a of the label 3 protrudes from the notches 45b to 45e of the suction head 45. Then, the X-direction positioning cylinder 47 is driven to move the suction head 45.
Is horizontally moved in a direction away from the edge member 43 (X direction). This movement is due to the notch 45b of the suction head 45.
The bottom surface of 45d is moved to a predetermined position where it abuts the reference guides 51 to 53, and the edge 3a of the label 3 protruding from the notches 45b to 45d abuts the reference guides 51 to 53 during the X direction of the label 3. Positioning is performed. Thereby, even if the label tape 41 has a variation in the punching position of the label 3 and the position where the label 3 is sucked by the suction surface 45a of the suction head 45 is not constant, the position of the label 3 in the X direction is predetermined. Corrected to correct position.

Subsequently, the Y-direction positioning cylinder 48 is driven, and the suction head 45 is moved in the Y-direction together with the X-direction positioning cylinder 47. When the Y-direction positioning sensor 55 detects the edge 3b of the label 3 protruding from the cutout 45e, this detection signal is input to the computer 56. As a result, the driving of the Y-direction positioning cylinder 48 is stopped, and the label 3 is positioned in the Y-direction. Also in this Y-direction positioning, since the stop position of the suction head 45 is determined by detecting the edge position of the label 3, even if the suction position of the label 3 varies, the position of the label 3 in the Y direction is correct. Will be fixed.

Thereafter, the sticking cylinder 46 is driven,
The suction head 45 is lowered toward the unit body 2 below. At this time, since the label positioning device 40 accurately positions the label 3 in both the X and Y directions, the opening 31 of the label 3 and the raised portion 1 of the unit body 2 are positioned.
Since the position of the label 3 coincides with that of 0, a part of the label 3 does not come into contact with and stick to the raised portion 10. Suction head 4
As the downward movement of 5 advances, the raised portion 10 projects from the opening 31 and enters the concave portion 45f, and the suction surface 4 of the suction head 45
When the front cover portion 26 of the label 3 attached to the label 5a contacts the front surface of the unit body 2, the front cover portion 26 is attached to the front surface of the unit body 2 by the adhesive material applied to the back surface of the label 3.

Next, the belt conveyor 61 is driven to convey the unit main body 2 to which the front cover portion 26 of the label 3 is temporarily attached to the first pressing roller station 65. As shown in FIG. 4B, when the unit main body 2 arrives at the first pressing roller station 65, the pressing roller 66 descends and the front cover part 26 and the bottom cover part of the label 3 are attached to the front surface and the bottom surface of the unit main body 2. Press 27. The pressing roller 66 reciprocates a plurality of times while pressing the cover portions 26 and 27 of the label 3 against the front surface and the bottom surface of the unit body 2. Thereafter, the belt conveyor 61 is driven and the unit body 2 is further moved to the second pressing roller station 6
7 (see FIG. 4).

In the second pressing roller station 67, as shown in FIG. 5, the pressing roller 69 supported by the L-shaped arm 68 presses the upper surface cover portion 25 of the label 3 onto the upper surface of the unit body 2 and adheres it ( A) Further, the back cover 24 is pressed against the back surface of the unit main body 2 and attached (B). Then, the pressing roller 69 finally presses the overlapping portion 23 against the surface of the bottom surface cover portion 27 adhered to the bottom surface of the unit main body 2 to adhere. Like the pressing roller 66, the pressing roller 69 also reciprocates a plurality of times.

Next, referring to FIG. 6 showing another embodiment,
The label positioning device 70 includes the reference guides 51 to 53.
Instead of, the X direction positioning sensors 73 and 74 are used. This is because when the label 3 is formed of a soft material without stiffness, the position of the label 3 is not determined even if the edge of the label 3 is brought into contact with the reference guide.
Especially effective. Further, instead of the X-direction positioning cylinder 47 and the Y-direction positioning cylinder 48, a biaxial robot 75 as shown is used. In this biaxial robot 75, a movable portion is fixed to the side surface of the sticking cylinder 46, and a Y-direction positioning device 77 that moves the suction head 72 together with the sticking cylinder 46 in the Y direction, and the Y-direction positioning device 77. And an X-direction positioning device 78 for moving in the X-direction. Also, this 2-axis robot 75
Are controlled by the computer 80.

Two notches 72a and 72b are formed on the lower edge of the suction head 72 on the side away from the edge member 43, and a notch 72c is formed on the lower edge of the X-direction positioning device 78 side. There is. Suction head 72 is label 3
Edge 3a of the label 3 is notched 72a, 7
2b and the edge 3b protrude from the notch 72c. After the suction head 72 has suctioned the label 3, the X-direction positioning device 78 moves the suction head 72 in the X direction together with the sticking cylinder 46 and the Y-direction positioning device 77. The X-direction positioning sensors 73 and 74 are notched 72
When the edge 3a of the label 3 is detected by entering the a and 72b, the computer 80 moves the X-direction positioning device 7
8 is stopped, and then the Y-direction positioning device 77
Moves the suction head 72 together with the sticking cylinder 46 in the Y direction. When the Y-direction positioning sensor 55 enters the notch 72c and detects the edge 3b of the label 3, the computer 80 stops driving the Y-direction positioning device 77.

In the above-described embodiment, the edge of the label partially protrudes from the notch of the suction head. However, for example, the size of the suction head is made slightly smaller than the label, and the edge of the label is the suction head. You may make it protrude from the whole surroundings. In addition, although the one using two cylinders (first embodiment) and the one using a two-axis robot (second embodiment) are exemplified as the means for moving the suction head in the XY directions, Other means, for example, a general-purpose robot hand may be used as long as the movement can be controlled in the XY directions. Further, in the first embodiment, the suction head is moved in the X direction to a predetermined position where the bottom surface of the cutout contacts the reference guide, but at the stop position of the suction head, the bottom surface of the cutout contacts the reference guide. It may be set at a predetermined position in front.

Further, as the reference guide for positioning in the X direction, the one in which three rectangular parallelepipeds are arranged in a straight line in the Y direction is used, but the present invention is not limited to this and, for example, the edge of the label is applied. The surface to be contacted may be a single rod-shaped member having a flat surface. In addition, the label supply direction is X as it is.
However, the X-Y directions can be freely set. That is, for example, the direction inclined by 45 ° from the label supply direction may be set as the X direction.

Further, although each sensor for detecting the edge of the label is of a reflective type, it may be of a transmissive type. In addition, a film unit with a lens is selected as a work for attaching a label. However, the present invention can be applied to any label use field that requires label attaching accuracy. The suction surface of the suction head is preferably covered with rubber or the like so as not to damage the surface of the label or the unit body. As a material for the label, besides PET or synthetic paper, polystyrene (PS), polypropylene (PP), or the like can be used.

[0034]

As described above, according to the label positioning method and apparatus of the present invention, the label is adsorbed and held parallel to the surface to which the work is attached, and each edge of the label in the XY direction is used as a reference. Since each position in the XY direction of the label is determined by contacting the guide or detecting the position of each edge by the sensor, even if there is a variation in the suction position between the suction surface of the suction head and the label, Labels can be positioned with high accuracy. Also, if the suction head is made smaller than the label in whole or part so that the edge of the label protrudes when the label is sucked, it is ensured that the edge of the label contacts the reference guide or is detected by the sensor. You can Even when the work is a film unit with a lens and a label having an opening corresponding to the ridge is attached to the front of the unit body having the ridge, the label does not come into contact with the ridge, and the label is accurately attached. Labels can be attached.
