Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a labeling device that affixes labels to objects that are continuously fed.

2. Description of the Related Art Conventionally, it has been widely practiced to attach labels displaying trademarks, manufacturing data, etc. to various products. Generally, this type of label has an adhesive surface formed on the back of the label and is supported on a band-shaped carrier, and is suitable for products that are produced in large quantities.
The label is attached to the product by an automatic device that peels off the labels one by one from the carrier and presses the adhesive surface onto the product.

As mentioned above, conventional labeling devices that automatically attach labels to objects have been designed to peel off a portion of the label from a label carrier in the vicinity of objects to be bound, which are continuously fed, so that the adhesive surface is not exposed. The label is supported so that the object to be pasted faces, and when the object to be bound passes near the label, the label is pressed against the object by a roller from the front side, or the label is sucked out one by one from the label carrier. There are known methods in which the suction stand is pressed against the object to be bound, or the label adsorbed on the suction stand is blown off toward the object by an air jet and affixed to the object.

However, in the case of a bell binding device using the above-mentioned roller, the label may be peeled off from the label carrier, or the label may be peeled off from the label carrier, or the label may be peeled off on the target body due to the suppressed state between the roller and the target body. The end position of the label changes. When labels are attached to products simply for the purpose of various indications, the attachment positions do not need to be specified very precisely, but such labels are used, for example, in the continuous production process of strips such as aluminum webs. It is also considered to be used as a mark for later removal of areas where defects are found through surface inspection, and in such cases the label must be affixed accurately to a predetermined position on the object to be affixed.

In addition, in the above-mentioned label pasting device that uses a suction table that is pressed against the object to be pasted, the feeding of the object to be pasted is stopped when the suction table is pressed, so that the pasting processing speed can be sufficiently increased. I can't. Furthermore, in an apparatus using a Zakujo stand that blows off the label with air, the label does not stick firmly to the object to be affixed. Moreover, in this case, since the label is blown off and supplied to the moving target object, there is a problem that the affixing position becomes inaccurate.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to accurately and firmly affix a label to a predetermined position of an object to be affixed while continuously feeding the object. The purpose of this invention is to provide a label binding device that is capable of.

The label pasting device of the present invention includes a suction drum, which is provided with a label suction portion using air suction on its circumferential surface, and is disposed at a position where the label suction portion can come into contact with the N objects to be pasted that are continuously fed. a drum driving means for driving the suction tram one rotation so that the label suction unit in contact with the object to be applied moves in the feeding direction of the object to be applied; drum drive control means for controlling the drum drive means so that the circumferential speed of the label suction section matches the circumferential speed of the label suction section;
a label supply means that partially peels off the carrier and sends the label to a predetermined position near the label adsorption part with the adhesive part facing the opposite side of the label adsorption part; and an air suction means for suctioning the air.

By using the above-mentioned drum drive control means to match the feeding speed of the object to be affixed to the circumferential speed of the label suction section of the drum, the label will not slip on the object to be affixed, and the label will be placed in the correct position. It will be attached to. In addition, since the label suction part of the suction drum as described above is pressed against the object to be bound, and the label adsorbed to the label suction part is affixed to the object to be bound, the label has a large binding force. and the label will be firmly attached.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an elevational view of a label tying device according to one embodiment of the present invention. The labeling device 1 of the present embodiment is used to affix a label to an aluminum web (thin plate) as described above as a mark indicating a surface defect location, and the labeling device 1 is fed from above to below. It is arranged on the side of the aluminum web 2.

The band-shaped label carrier 3 whose side 1@ part is shown in FIG. part)
As shown in FIG. 2, which is a perspective view viewed from above, marking labels 4 having an adhesive layer 4a formed on a part of the back surface are carried at predetermined pitch l.
is carried on the label carrier 3 by the action of the adhesive layer 4a, but as is well known, the label carrying surface (lower surface in FIG. 2) of this type of label carrier 3 is smoothed, When the label 4 is pulled away from the label carrier 3 with a certain amount of force, it is easily peeled off from the label carrier 3 while leaving the adhesive layer 4a on the back side.

As shown in FIG. 1, the label carrier 3 is wound and stored on a delivery reel 5, and the leading end unwound from the delivery reel 5 is hung on a pass roller 6 and then placed between a guide pin 7 and a pass roller 8. The guide bins 10,
The film is applied to a drive roller J1, a pinch roller]2, and finally wound up by a take-up reel]3.

The drive roller 1] is driven by a pulse motor 14, for example.
The label carrier 3 is rotated in the direction of arrow B in the figure by the operator, and the label carrier 3 is sent in the direction of the winding wheel 13. And this pulse motor 1
40 The amount of rotation is controlled as will be described in detail later, and the amount of feed of the label carrier 3 is determined. The winding wheel 13 is rotated by a torque motor 15 in the direction of arrow C in the figure, and winds up the label carrier 3 sent by the drive roller 11. The portion of the label carrier 3 stretched between the guide pin 7 and the pass roller 8 is pressed from above and below by a pair of rubber presser rollers 1.6.17 to prevent sagging or twisting. The position is detected at this temperature i4 by a photoelectric device. That is, as shown in detail in FIG. 3, one presser roller 16 is
It consists of two rollers 16a and 1.6b rotatably supported above and below a cylindrical fixed shaft 18 at a distance from each other, and there is a window in the central part of the fixed +lql+ 1s that faces the label supporting body 3. 18a has been established. and the first
As shown in the figure, a light emitter 19 is disposed within the cylindrical fixing [llIb] 8 and emits detection light that passes through the window 18a and is directed toward the label carrier 3. The other presser roller 17 is also formed in the same manner as the presser roller 16, and a light receiver 20 is disposed inside its fixed shaft 18' to receive the detection light through a window provided in the fixed shaft 18'. There is. The label carrier 3 is made of a material with good light transmittance, while the label 4 is made of a material with a high light blocking property. Therefore, by detecting the presence or absence or strength of the detection light detected by the light receiver 20, it is possible to accurately detect the leading or trailing end of the label 4 on the label carrier 3-1.

The delivery reel 5 that winds and stores the label carrier 3 is equipped with a known brake that generates an appropriate load against the winding force of the label carrier 3 so that the label carrier 3 that is sent out does not sag. Means (not shown) may be provided.

The beer sprays 1 and 9 are conventionally used to peel off a label from a label carrier, and are used to suddenly remove the label carrier 3 which is elastically pressed against the beer plate 9 by the guide plate 9a. By folding at an angle,
Peel off the label 4 from the label carrier 3 (see Figure 4)
.

A suction drum 22 is disposed near the beer plate 9 and is stopped from rotating so that one label suction portion 22a is located near the surface of the label 40 peeled off from the label carrier 3 as described above. It is set up. For example, this suction drum 22 is rotationally driven by a pulse motor 21 in the direction indicated by the arrow in the figure, that is, in a rotation direction such that the portion facing the aluminum web 2 moves in the same direction as the feeding direction of the aluminum web 2. It looks like this,
Also, when rotated as described above, the label suction part 2
22 is arranged at a position where it can come into contact with the aluminum web 2. The circumferential surface of the label suction section 22a is made of a material with a high friction coefficient, such as rubber, and is formed in a shape that forms part of a cylindrical surface centered on the rotation center of the suction drum 220. As shown in FIG. 4, a large number of air holes 22b communicating with the inside of the suction drum 22 are bored.

The fixed hollow pipe 23 (see FIG. 1) that rotatably supports the suction drum 22 is extended to a position where its tip surface slides into contact with the inner surface of the upper bottom plate 22c of the drum 22, and the outer peripheral surface thereof is Two partition plates 24 are fixed that extend in a direction substantially parallel to the aluminum web 2 and make sliding contact with the inner circumferential portion 22d of the drum 22. The interior of the hollow pipe 23 is partitioned by a partition plate 23aK that matches the partition plate 24, and through holes 231) and 23C are provided in the pipe peripheral walls on both sides of the partition plate 23a, respectively. Partition plate 23
The inner pipe space 23d on the side closer to the aluminum web 2 than a is communicated with air suction means such as a vacuum pump, and the inner pipe space 23e on the opposite side is communicated with air discharge means such as a blower. Therefore, the aluminum web 2
Air is sucked into the drum 22 from the air hole 22b of the label suction unit 22a located on the side, and the label suction unit 2 located further from the aluminum web 2 than the partition plates 23a and 24
Air is discharged to the outside of the drum 22 from the air hole 22b of the drum 2a.

All the elements other than the aluminum web 2 explained above are the substrate 2.
5, and the substrate 25 is supported on a pedestal 28 via a left-right position adjustment table 26 that adjusts the position of the aluminum web 2 in the width direction, and a front-rear position adjustment table 27 that adjusts the distance from the aluminum web 2. ing. Further, a backup roller 29 that is driven by the aluminum web 2 is provided at a position facing the suction drum 22 with the aluminum web 2 in between.

The operation of the apparatus of this embodiment having the above configuration will be explained below. FIG. 5 schematically shows the control system of the labeling apparatus of this embodiment. A detection end 30 is installed a predetermined distance upstream of the satanyong drum 22 for inspecting the surface of the aluminum web 2 that is fed at a constant speed. A detection signal S1 is inputted from the detection end 30 to the pulse generation circuit 31 (this inspection for surface defects is performed by tracking the surface for a predetermined length further upstream than the detection end 30, and the defect is detected by the detection end 30). (The detection signal S1 may be output from the detection end 30 when the detection end 30 reaches this point.) The pulse generation circuit 31 receives the detection signal S+ and inputs a drive start signal S2 consisting of a pulse wave as shown in FIG. 6(a) to the pulse control circuit 32, thereby driving the pulse motor 14.

The pulse motor 14 is driven by a pulse signal S3 set by the pulse control circuit 32 with a rotation waveform as shown in FIG. 6(b). That is, initially the predetermined base speed is 1A.

After rotating for a predetermined time, the rotation increases at a predetermined acceleration, and after driving at a predetermined top speed V1 for a predetermined time, the rotation decreases to the base speed NAO at a predetermined deceleration. When the pulse motor 14 is thus driven to rotate in a predetermined pattern, the drive roller 11 is rotated by a predetermined rotation angle, and the label carrier 3 is fed by approximately the pitch l of the label 4. However, strictly speaking, the feed amount of the label carrier 3 is set to be smaller than the pitch l. Then, the label carrier 3 is further fed by a small amount due to the base speed ↑0, and the label carrier 3 is actually moved by a pinch l.
(t2), a stop signal S5 is input from the label position detection circuit 33 to the pulse control circuit 32, and feeding at this base speed/IAO is stopped. . The label carrier 3 is therefore fed exactly in pitch.

When the label carrier 3 is fed only with a predetermined pinch in this way, the label 4 is transferred to the beer plate 9 as described above.
The suction drum 2 is peeled off a predetermined length from the label carrier 3 by the suction drum 2 and stopped at the rotating position shown in FIG.
201 is arranged near one label adsorption section 22a.

That is, the beer plate 9, the pulse control circuit 32
, a light emitter 19 and a light receiver 20, a label position detection circuit 33,
The pulse motor 14- and the drive roller 11 constitute a label supply means for feeding the label 4 to a predetermined position near the adsorption section 22a.

The label 4, which has been peeled off by the beep sheet 9 and whose surface faces the suction drum 22 side, is adsorbed by the label adsorption section 22a where air suction is performed as described above.

Then, when the rotation speed of the pulse motor 14 decreases from the top speed i/-1 to the base speed vO (1+) as described above, the pulse control circuit 32 outputs a drive start signal S.
6 is input to the pulse control circuit 34.

The pulse control circuit 34 receives this drive start signal S6, outputs a pulse signal S7, and controls the pulse motor 21 as shown in FIG.
) Rotate with the rotation waveform shown in (). That is, the pulse motor 21 first rotates at a predetermined base speed ■0 for a predetermined time, then increases in rotation at a predetermined acceleration, rotates at a top speed ■1 described later for a predetermined time, and then rotates at a predetermined deceleration up to the base speed ■o. Descend. Suction drum 22 rotationally driven by this pulse motor 21
A rotation angle detection device 35 consisting of, for example, a rotating disk provided with a light passage hole and a photoelectric device is connected to the rotation angle detection device 35, and when the suction drum 22 rotates 900 times (t3), a pulse control circuit is transmitted from the rotation angle detection device 35. A stop signal S8 is input to 34, and the tram rotation at this base speed VO is stopped.

When the Zakujon drum 22 is rotated 900 times as described above, the label suction part 22a that has suctioned the label 4 is attached to the aluminum web 2 supported by the backup roller 29.
Since the label 4 is in pressure contact with the core label 4 through the core label 4, the label 4, which was attracted to the label adsorption part 22a with the adhesive layer 4a facing outward, is attached to the side edge 2 of the aluminum web 2 by the adhesive layer 4a.
It can be pasted on a (see Figure 4). As is clear from FIG. 6, since the time from when the surface defect point passes the detection end 30 and the drive start signal S2 is output until the pulse motor 21 starts driving is kept at a predetermined value, the aluminum 2 feed speed and suction drum 2 from the detection end 30.
By appropriately setting the distance up to 2, the label 4 can be attached to the surface defect location.

As shown in FIG. 5, a pulse generator 37, which constitutes drum drive control means together with the pulse control circuit 34, is connected to the transport system 36 for the aluminum web 2, and the feed speed of the aluminum web 2 is detected. . A feed rate signal S9 output from the pulse generator 37 is input to the pulse control circuit 34. The pulse signal S7 is controlled by the feed speed signal S9, and the pulse motor 21
The top speed (1) is set to a speed at which the circumferential speed of the label suction section 22a matches the feeding speed of the aluminum web 2. That is, as shown by the virtual line in FIG. 6(C),
The top speed ■1 is adjusted by changing the length of the acceleration period following rotation with the base speed ■0.

By making the circumferential speed of the label suction part 22a match the feed speed of the aluminum web 2 in this way, the label 4 that has been suctioned by the label suction part 22aK does not slip on the aluminum web 2, thereby causing positional shift. Kotona (It will now be firmly attached to the desired position.)

As mentioned above, since the pulse motor 21 rotates at the top speed Vl for a predetermined period of time, the rotation angle of the suction drum 220 due to this rotation changes depending on the magnitude of this top speed 1.
is finally rotated by exactly 90 degrees and stopped by rotating at the final base speed Vo as described above.

The label 4 affixed to the side end 2a of the aluminum web 2 is
This shows the location of surface defects on the aluminum web 2. Therefore, later, a surface defect location is found using this label 4 as a landmark, and appropriate measures such as removing the location are taken.

10,000 Even if there is a mistake in the label 4 and the label 4 is not attached to the aluminum web 2 and remains on the label suction part 22a, the next time the Zakujo drum 22 rotates 90 degrees,
Since air is discharged from the label suction section 22a as described above, the remaining label 4 is blown away from the label suction section 22a, and the label suction section 22a can normally suction a new label 4 next time. .

As explained above, the label binding device of this embodiment is capable of pasting the label 4 while continuously feeding the aluminum web 2, which is the object to be pasted, so that it can be fed at a speed of, for example, 50 m/min. It is possible to attach the dowel 4 to the aluminum web 2 at a high speed of 4 sheets/sec. In addition, in the apparatus of this embodiment, the feeding of the label carrier 3,
220 rotations of the suction drum are carried out at different times, but the feeding of the label carrier 3 and the suction tram 2
If the 20 rotations are performed overlapping each other in synchronization, the processing speed for attaching the label 4 can be further improved. Furthermore, the number of label suction parts provided on the Zakujo drum is not limited to four in this embodiment,
It can be set to an appropriate number. Furthermore, although the apparatus of the above embodiment is used for attaching a label 4 to an aluminum web 2, the label attaching apparatus of the present invention can be applied to continuously fed belt-shaped or bar-shaped covers other than such an aluminum web. It can of course be used not only for knotted bodies but also for a large number of bound bodies sent at predetermined intervals by a conveyor means.

As explained in detail above, the label tying device of the present invention is capable of firmly and accurately affixing a label to an object to be affixed without stopping the object to be affixed.
This is especially advantageous when attaching a label to a subject (C) that is sent at high speed.
