The lever 42 is biased by its own weight to rotate counterclockwise as indicated by the arrow D1. As shown in FIGS. 1 and 3, the counterclockwise rotation of the lever 42 in the normal state is controlled by the contact of the support surface 42 a formed at the tip with the second inclined cam surface 41 b of the cam member 41. Has been stopped. In this state, one side surface 42b of the lever member 42 forms a horizontal plane that is continuous with the main cam surface 41a of the cam member 41.

Below the upstream side of the cam member 41, a label mounting table 44 is fixed. On the other hand, a packing box 46, which is a member to be pasted, is provided in a direction in a direction perpendicular to the rails 26 (in FIG. 1, the front and back sides of the paper) in the member to be adhered supply section 45 provided on the downstream side of the cam member 41.

8 is provided with a coating roller 49 in which a substantially half portion in the radial direction is accommodated. The coating roller 49 is driven to rotate by a coating motor 50 (only shown in FIG. 2).

The control unit 51 includes a microcomputer, a storage device, and the like. Based on input signals from various operation switches (not shown) and input signals from the detection sensor 17 and the like, the feed drive motor 12, the reciprocating drive motor 30,
The operation of the pump 40, the coating motor 50, and the like is controlled.

Next, the operation of the labeling apparatus having the above-described configuration will be described. First, the control unit 51 determines that the continuous paper 3 The feed drive motor 11 is driven so as to intermittently move by the interval.
Further, the control unit 51 operates the lifting device 22 to lower the upper cutting blade 21 every time the continuous paper 3 moves by the interval of the pitch mark 6 as described above. As a result, one label 53 is cut from the leading end of the continuous paper 3 and is mounted on the label mounting table 44.

When the horizontal moving seat 27 is at the initial position, the suction head 38 is located above the label mounting table 44 as shown by a dashed line in FIG. The control unit 51 operates the pump 40 in synchronization with the placement of the label 53 cut from the leading end of the continuous paper 3 on the label mounting table 44 as described above. When the pump 40 operates, the suction holes 38
Air is sucked from a, and the cut label 53 is sucked on the lower surface of the suction head 38 by the negative pressure generated as a result.

Next, the control unit 51 determines that the belt 31 has an arrow C
The reciprocating drive motor 33 is driven so as to move in one direction. As the belt 31 moves, the horizontal moving seat 27 and the vertical moving seat 36 move in the direction of the arrow C1.
The cam roller 39 is guided by the first inclined cam surface 41b of the cam member 41 as shown in FIG. As a result, the vertical member 36
Move upward in the vertical direction, and the suction head 38 moves obliquely upward to the left in FIGS.

When the horizontal moving seat 27 further moves leftward in the figure, the cam roller 39 is guided by the main cam surface 41a. While the cam roller 39 is guided by the main cam surface 41a, the vertical member 36 does not move in the vertical direction, and the suction head 38 moves horizontally.

When the suction head 38 reaches above the adhesive application roller 49, the control unit 51 operates the application motor 50 to rotate the adhesive application roller 49. As a result, on the lower surface of the label 53 held by the suction head 38,
An adhesive is applied from an adhesive application roller 49. In addition,
The mechanism for detecting that the suction head 38 has reached above the adhesive application roller 49 is not particularly limited.
Such a mechanism can be provided by a combination of a member interlocked with the belt 31 and a limit switch.

The horizontal moving seat 27 further moves leftward in the drawing, and the cam roller 39 is guided from the main cam surface 41a to the side surface 42b of the lever 42, and the suction head 38
Continues to move horizontally. The cam roller 39 is connected to the lever 4
In the figure of the second side surface 42b, the cam surface supporting the cam roller 39 disappears beyond the left end, so that the vertical moving seat 36 moves vertically downward as shown by the two-dot chain line in FIG. As a result, the label 5 coated with the adhesive
3 falls on the upper surface 46a of the packing box 46.

Thus, the label 5 is placed on the upper surface of the packing box 46.
When 3 is attached, the control unit 51 stops the pump 40. Subsequently, the control unit 51 drives the transport motor 33 in the reverse direction to move the belt 31 in the direction of arrow C2.
As a result, when the horizontal moving seat 27 moves horizontally in the direction of arrow C2, the cam roller 39 is guided by the second inclined cam surface 41c of the cam member 41 and moves diagonally upward to the right, and the vertical moving seat 36 moves upward in the vertical direction. I do. As a result, the suction head 38 moves diagonally right upward.

The cam roller 39 which has reached the upper end of the second inclined cam surface 41c pushes up the lever 42 as shown in FIG. 4 and rotates counterclockwise as shown by the arrow D2. The cam roller 39 passes through the second inclined cam surface 41c and passes through the main cam surface 4c.
When the lever 42 moves to 1a, the lever 42 rotates clockwise by its own weight, and the contact surface 42a is locked to the second inclined cam surface 41c. Further, the cam roller 39 is guided by the main cam surface 41a and the first inclined cam surface 41b and moves rightward in the drawing, and the suction head 38 returns to the initial position.

By repeating the above operation, the packing box 4
The label 53 is continuously attached to the upper surface of the label 6.

In the labeling apparatus 1 of the first embodiment, the only motor for driving the suction head 38 is the reciprocating drive motor 33 for horizontal movement, and the movement of the suction head 38 in the vertical direction is controlled by the cam roller 39. This is realized by a cam mechanism including the cam member 41. In this regard, the labeling device 1 has a simple structure and can be manufactured at a lower cost than conventional devices of this type. Further, since the cam mechanism has a simple structure including the cam roller 39 and the cam member 41, a failure or the like hardly occurs.

(Second Embodiment) The second embodiment shown in FIGS.
The labeling device 1 according to the embodiment applies a label to the side surface of the member 46 to be applied, and differs from the first embodiment in the structure of the cam mechanism.

At the lower end of the vertical moving seat 36, a suction head shaft 56 to which the suction head 38 is fixed at the end is rotatably mounted. A lower end of a link member 57 is fixed to the suction head shaft 56 at an intermediate position between the suction head 38 and the vertical movement seat 36. This link member 57
A cam roller 59 that engages with the first cam member 58 is attached to the upper end of the cam roller 59.

A fixed shaft 60 is fixed to the vertical movement seat 36 on the side opposite to the suction head shaft 56, and a cam roller 61 is rotatably attached to the tip of the fixed shaft 60. The cam roller 61 is a second cam member 62
Is engaged.

As described above, in the second embodiment, two sets of cam mechanisms are provided. Among them, the cam roller 61 and the second cam member 62 are the cam rollers 3 in the first embodiment.
9 and the cam member 41. The second cam member 62 includes a main cam surface 62a extending horizontally in parallel with the rail 26, and an inclined cam surface 62b connected to the upstream side of the main cam surface 62a and inclined downward toward the upstream side. I have.

On the other hand, the first cam member 58 has a first horizontal cam surface 58a and a second horizontal cam surface 58a lower than the first horizontal cam surface 58a in FIG. A second horizontal cam surface 58b having a small distance from the horizontal cam surface 62a of the cam member 62; The first and second horizontal cam surfaces 58a and 58b are connected by an inclined cam surface 58c that is inclined downward toward the downstream side.

As in the first embodiment, the continuous paper 3 is intermittently unwound by the interval of the pitch marks 6 by the feeding mechanism 11 and its leading end is cut into one label 53 by the cutting mechanism 19. . The cut label 53 is placed on the label placing table 44.

When the horizontal moving seat 27 is at the initial position, the suction head 38 is at the position shown by the dashed line in FIG. In this state, the label 53 on the label mounting table 44 is sucked by the suction head 38.

The horizontal moving seat 27 is moved from this initial position by an arrow C.
When the cam roller 61 moves in one direction, the cam roller 61 is guided from the inclined cam surface 62b of the second cam member 62 to the horizontal cam surface 62a, and as a result, the suction head 38 moves upward in the vertical direction.

When the suction head 38 reaches the position above the adhesive applying mechanism 25, the adhesive applying roller 49 is driven to rotate, and the adhesive is applied to the label 53 sucked by the suction head 38.

When the horizontal moving seat 27 further moves in the direction of arrow C1, the cam roller 59 moves the first cam member 58 to the first position.
From the horizontal cam surface 58a to the inclined cam surface 58c. When the cam roller 59 moves on the inclined cam surface 58c, the link member 57 rotates clockwise as indicated by an arrow F1, and accordingly, the suction head shaft 56 and the suction head 38 also rotate clockwise. Then, the cam roller 59
Reaches the second horizontal cam surface 58, the suction head 38 rotates clockwise by 90 degrees, and the label 53 is oriented horizontally.

Even if the horizontal moving seat 27 moves further in the direction of arrow C 1, the suction head 38 keeps this posture, and the adhesive of the label 53 The surface on which is applied is pressed.
When the horizontal moving seat 27 moves in the direction of the arrow C2 after the label is attached, the suction head 38 rotates counterclockwise as shown by the arrow F2 and returns to the original posture. The above operation is repeated, and the label is continuously attached to the side surface 46b of the packing box 46.

In the labeling device of the second embodiment, the motor for driving the suction head 38 is only the feed drive motor 50 for horizontal movement, as in the first embodiment. Is realized by a cam mechanism including the cam roller 59 and the first cam member 41. In this regard, the labeling device 1 has a simple structure and can be manufactured at a lower cost than conventional devices of this type.

The other configuration and operation of the second embodiment are the same as those of the above-described first embodiment. Therefore, the same components are denoted by the same reference numerals, and detailed description is omitted.

Note that the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, using continuous paper that has not been subjected to printing corresponding to each label, printing corresponding to each label is performed by a printer 60 interposed between the continuous paper roll 4 and the labeling device 1 as shown in FIG.
