Description

[0001]
BACKGROUND OF THE INVENTION
In particular, the present invention relates to a label attaching apparatus that attaches a label to an appropriate position of an object to be attached using only a fan without using an air compressor.
[0002]
[Prior art]
Conventionally, a labeling device (labeling robot) requires an air compressor (hereinafter, simply referred to as a compressor, as appropriate) in order to adsorb a label on an adsorption board (see, for example, Patent Document 1).
In factories that use a large number of labeling equipment, a large compressor room is installed and air pipes are installed from this compressor room to the place where the labeling equipment is used. Even when a small number of labeling devices are used, it is necessary to operate a large-sized compressor, which has a problem of adversely affecting the environment, such as noise during driving of the compressor and air pollution due to exhaust.
[0003]
Moreover, since the label sticking device is installed near the conveyor to which the sticking object is conveyed (see, for example, Patent Document 2), between the label sticking device and the tip of the air tube piped from the compressor chamber. There is a problem that it is necessary to connect with a flexible tube and the like, and the installation position is limited, or the connection tube is exposed to the floor and becomes an obstacle.
[0004]
In order to solve the above-mentioned problems, a labeling device in which a vacuum generator (compressor) as a second holding unit is mounted on a gantry has been proposed (see, for example, Patent Document 3). According to this proposal, since a small vacuum generator (compressor) is mounted on the frame of the labeling device, piping from a large vacuum generator (compressor chamber) and piping of the air pipes installed in the factory are installed. Since there is no need for a tube between the tip and the labeling device, the conventional capital investment is high and the problem of obstructing the tube is solved, but the environment such as noise and air pollution is eliminated. There has been a problem that the adverse effects on the environment have not been solved.
[0005]
Therefore, the applicant once proposed a label sticking device using only a fan without using an air compressor (see, for example, Patent Document 4). This is a proposal to improve this.

[0015]
Next, a usage example of the label sticking device according to the present embodiment will be described.
[0016]
When the label sticking apparatus 1 is started up, the drive motor 54 rotates and conveys the label continuous body 9 to the print head 50 side. After the desired printing is performed on the label L by the printer 5, the label L is adsorbed to the adsorbing device 3 at the timing when it is peeled off from the mount 8. That is, the fan 18 of the suction device 3 standing by downstream of the peeling plate 7 rotates and discharges the air A from the opening 19, and the “hollow part” including the hollow groove 16 and the connecting groove 17, and the narrow space Air is sucked from the suction hole 11 through the communication passage 15 formed by the narrow communication pipe 60 and the narrow portion 61, and the label L gradually peeled off from the mount 8 by the peeling plate 7 is gradually sucked onto the suction surface 12.
At this time, the fan 72 of the fan section 71 for the auxiliary nozzle rotates and air is blown to the label L from the auxiliary nozzle 70, so that the label L is held more securely on the suction surface 12. When the holding of the label L with respect to the suction surface 12 is completed, the fan 72 stops and the blowing of air from the auxiliary nozzle 70 stops.
[0017]
Next, the second pulse motor 25 rotates and the second moving body 22 moves in the X direction in FIG. 1, whereby the suction device 3 that sucks the label L moves in the X direction, and the X direction. When the predetermined position is reached, the third pulse motor 26 further rotates and moves in the Y direction.
[0018]
Next, the first pulse motor 24 rotates, the suction device 3 that is sucking the label L is moved in the Z direction, that is, the height direction, and the suction surface 12 is pressed against the adherend M. When the label L is pressed against the adherend M, the sticking sensor 55 detects the end of sticking of the label L to the sticking object M, stops the rotation of the fan 18, and stops sucking air from the suction hole 11. .
[0019]
Then, in reverse order, the first pulse motor 24, the third pulse motor 26, and the second pulse motor 25 rotate in this order, and the suction device 3 is placed at the label suction position downstream of the peeling plate 7. To return.
[0020]
As described above, since the label sticking device can be realized only by using the fan 18, it can be introduced at a low cost because there is no need to use a compressor as in the prior art. Negative effects on the environment are avoided.
[0021]
In addition, by the operation of the fan 18, the air A from the suction hole 11 through the “hollow part” formed by the hollow groove 16 and the connecting groove 17 and the communication path 15 formed by the narrow communication pipe 60 and the narrow part 61. The suction hole 11 communicates with the hollow grooves 16, 16... And the “hollow part” composed of the “grooves” of the connecting grooves 17, so that one of the expanded holes is not a “groove”. Compared to the conventional art connected to the “hollow part”, the suction force with respect to the suction hole 11 is increased, and further, the air is sucked into the fan box 14 through the narrow communication passage 15, so the suction force is further increased. Is done.
[0022]
Further, the suction device 3 attached via the shaft 20 is moved in the height direction (Z direction) by the first moving body 21 and moved in the X direction by the second moving body 22, and further, The third moving body 23 is moved in the Y direction, and each moving body 21, 22, 23 is slid by a minute distance under the rotation of the pulse motors 24, 25, 26. The positioning of the sticking position of the label L with respect to the sticking object M is performed more accurately than in the conventional case using an air cylinder.
[0023]
【The invention's effect】
As described above, the label sticking device according to the present invention can be realized only by using a fan, so that it is not necessary to use a compressor as in the prior art, and can be introduced at a low cost, and the compressor is driven. There is an effect that there is no adverse effect on the environment such as noise caused by air and air pollution caused by exhaust.
[0024]
In addition, since the air is sucked from the suction hole through the hollow groove and the connection groove and the narrow communication path by the operation of the fan, the suction hole is communicated with the hollow box composed of the hollow groove and the groove of the connection groove. Since air is sucked through the narrow communication path, there is an effect that the suction force is further increased.
[0025]
According to the second aspect of the present invention, the suction device attached via the shaft receives the rotation of the first pulse motor for sliding, slides in a minute distance and height direction, and performs the second movement. The body is moved in the width direction of the label, and further moved in the longitudinal direction of the label by the third moving body, and each of the first to third moving bodies is moved by the first to third slide pulse motors. Since the minute distance and movement are possible, there is an effect that the label can be accurately positioned on the object to be pasted.
[0026]
According to the third aspect of the present invention, since the auxiliary nozzle using the fan that blows air to the label being sucked is completed until the label holding by the suction surface is completed, the label is surely held on the suction surface. Become.
