DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-separable label sticking apparatus for directly sticking a non-separable label (hereinafter, referred to as a non-separable label) cut on an object to be stuck (work).

[0002]

2. Description of the Related Art In general, a so-called non-separable label, in which a surface (one side) of a tape-shaped label body made of a film or the like is formed as a printing surface and a back surface (the other side) is formed as an adhesive surface (adhesive surface), is rolled up. As a non-separable label sticking device, the set tape-shaped non-separable label is fed out, and the label piece cut into a suitable width (length) or the die-cut label piece is directly stuck to the wall surface of the separately fed work by sticking means. Various types are known.

Here, as a basic method of directly applying the cut non-separable label to the work, as shown in FIG. 4, the front surface is printed on the printing surface Aa and the back surface is the adhesive surface (adhesive surface) Ab.
The tape-like non-separated label A is fed from a set position where it is wound into a roll, cut appropriately for each fixed dimension, and the separated label piece A 'is fed separately by a known sticking means. It is to be attached to a wall surface (adhering surface) Ba.

As a specific mode, as shown in FIG. 5, for example, a tape-shaped non-separable label A having a printing surface Aa on the roll surface and an adhesive surface Ab on the back surface is appropriately fed out with a feed roller C as shown in FIG. The sheet is passed between a pair of a die-cut roller D and a die-cut anvil roller E which are opposed to each other. At the time of the pass, a predetermined die is cut with a die-cutting blade F provided on the die-cut roller surface, and the scrap tape A ″ is wound around the other. In the tension-type non-separable label sticking apparatus configured to take the non-separable label A, the non-separable label A is disposed with the adhesive surface Ab facing the die cut roller D side.
And a so-called die-cut shape cut is made.

[0005] That is, the conventional label A is cut from the adhesive surface Ab side, and the stamped label piece A 'of a predetermined shape is placed on the suction die-cut anvil roller E with the adhesive surface Ab facing outward. After the transition, the die-cut anvil roller E rotates and the adhesive surface Ab of the label piece A 'that has reached the opposite position from the cut side directly faces the wall surface Ba of the separately fed work B.
The label piece A 'is pressed and adhered.

[0006]

However, in the cutting step of cutting out (or releasing) the non-separable label A according to the above embodiment, the adhesive surface A of the non-separable label A is merely used.
Since the cutting operation is performed by pressing the die-cutting blade F of the die-cut roller D against the die-cutting roller b, the adhesive surface Ab easily adheres to the blade surface of the die-cutting blade F. For this reason, if the die cut roller D side is periodically separated and the blade portion of the die cutting blade F is not washed with a cleaning solvent or the like, the sharpness is reduced, so that troublesome maintenance is required, and at least cleaning for cleaning the blade is required. Equipment and cleaning solvents are also required, resulting in an inefficient labeling operation as a whole.

In view of the above circumstances, the present invention guides a tape-shaped non-separable label to a die-cut roller (for insertion).
An object of the present invention is to provide a non-separable label sticking apparatus that solves the above-mentioned problem by changing the roller so that the printing surface side faces the die-cutting blade (or the uncut blade) of the roller so that the blade body does not directly contact the adhesive surface. It was done.

[0008]

According to the present invention, there is provided a die-cut roller having a predetermined die-cutting blade provided on the outer periphery thereof and a suction-type die-cut anvil roller opposed to each other, and a roll-wound surface between the die-cut roller and the die-cut anvil roller. The tape-shaped non-separable label with the adhesive side on the back side
A sticking suction arm for rotating, which faces a discharge position of a shape-cut label piece to be suction-transferred by the die-cut anvil roller, wherein the printing surface is inserted and disposed so as to face the die-cut roller. A rotating type suction drum having a side-by-side arrangement, a label reversing means for separating the label piece on the die-cut anvil roller side with the adhering suction arm to make the adhesive surface outwardly reversibly supported, and The pressure-sensitive adhesive surface of the label piece supported by rotation is pressed against a separately supplied work wall surface.

Also, a die-cut roller provided with a predetermined cutting blade on the outer periphery and a suction-type die-cut anvil roller are installed to face each other, and the surface to be rolled between the die-cut roller and the die-cut anvil roller has a printing surface and a back surface has an adhesive surface. With the tape-shaped non-separated label, the printing surface is inserted and disposed to face the die-cut roller side to constitute a printing-surface-side cut mechanism, and the non-separated label end portion having a predetermined length on the front side from the cutting position of the die-cut roller. The suction guide belt is installed in parallel, and a rotary suction drum having a sticking suction arm which rotates and faces the discharge position of the shape-cut label piece to be transferred by suction of the die-cut anvil roll is juxtaposed. The suction arm separates the label piece on the die-cut anvil roll side, and the adhesive surface is exposed to the outside and inverted. A label reverse moving means is a pressure-sensitive adhesive surface of the support label piece in rotation of the sticking suction arm those presses separately workpiece wall to be fed.

In this case, the sticking suction arm has a telescopic arm configuration.

The suction guide belt is a caterpillar type silicon belt.

As described above, this label sticking apparatus is arranged such that the printing direction of the tape-shaped non-separable label introduced between the die-cut roller and the die-cut anvil roller is positioned on the die-cut roller side with the die-cutting blade with the printing surface of the label. Since the guide is directed to the adhesive surface, the cut (die cutting) for the fed non-separable label is performed from the printing surface side, so that the adhesive of the adhesive surface does not adhere to the blade portion of the die cutting blade.

Of course, positioning the adhesive surface on the die-cut anvil roller side means that the adhesive surface of the die-cut label piece is attracted by the suction action of the roller itself so that the adhesive surface does not face outward, so that the roller rotates. Therefore, the label piece cannot be attached to the work, so that the label piece is once inverted so that the adhesive surface is exposed to the outside.

That is, the label piece having a predetermined shape with the adhesive surface on the die-cut anvil roller side is rotated by a predetermined angle and reaches the discharge position opposite to the cut position.
It is necessary to invert so that the adhesive surface faces outward. At this time, the sticking suction arm of the rotary suction drum arranged side by side with the die-cut anvil roller is rotated to face, and the outward printing surface is sucked and separated, so that the label piece is forcibly transferred to the suction surface of the suction arm. The adhesive surface is used as an outwardly exposed reversal support.

Thereafter, when the suction drum is rotated by a predetermined angle, the label piece is carried by the suction arm with the adhesive surface exposed, and is directly pressed against the wall surface of the work which is separately fed at the next stage, and a predetermined label is applied.

In this case, if the suction arm of the rotary suction drum is configured as a telescopic arm, fine adjustment can be made according to the transfer interval to the work and the degree of pressing.

The same applies to the case where the blade of the die-cut roller is not a die-cutting blade but a cut-off blade (straight blade). In other words, even in a type in which the tape-shaped non-separable label is entirely cut out for each fixed dimension (length), basically, the non-separable label is inserted into the die cut roller side with the printing surface facing the same as described above. In addition, since the tension is not applied to the type where the tape is cut at the die-cut roller, an auxiliary suction guide belt is arranged in parallel to the position in front of the die-cut roller, and the free end of the non-separator label that is in the free state is securely fixed to the die-cut roller and die-cut anvil roller. Let me lead between.

Since the non-separable label is cut from the printing surface side by the cut-off blade of the die-cut roller, a fixed size can be cut off without the adhesive being directly attached to the blade portion. The label pieces sucked and wrapped around the die-cut anvil roller are forcibly separated by the suction arm of the adjacent suction drum, and the adhesive surface is exposed. Can be.

The suction guide belt may be a silicon belt having a simple structure, and the end portion of the non-separable label is sucked and conveyed by the belt and guided between the die-cut roller and the die-cut anvil roller without any trouble.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a non-separable label sticking apparatus according to an embodiment of the present invention.

FIGS. 1 and 2 show an embodiment of a tension-type non-separable label sticking apparatus in which a predetermined-shaped label cut is made by a die cutting method. Numeral 1 is a tape-shaped non-separable label made of a film or the like having a printing surface 1a on the front surface of which the base end is rolled around the core 2 and an adhesive surface 1b on the back surface. Between the die-cut roller 4 and the suction-type die-cut anvil roller 5 which are opposed to each other, the printing surface 1a is inserted and the adhesive surface 1b is directed toward the die-cut anvil roller 5 side, and the die-cut roller is mounted on the print surface 1a. The printing surface side cutting mechanism 7 is configured to abut a predetermined cutting blade 6 provided on the outer periphery of the printing surface 4. Reference numeral 8 denotes a rotary suction drum provided with a sticking suction arm 9 which rotates and faces in parallel at a discharge position 5a opposite to the cut position of the die cut anvil roller 5; Label piece 1 'that is absorbed and wound
Are forcibly separated by suction by suction air applied to a hose portion 8a provided on a shaft core portion of the suction drum 8, thereby forming a label inversion moving means 10 for changing the adhesive surface 1b to an outward exposure. Reference numeral 11 denotes a work transfer path arranged at a position where the label piece 1 'adsorbed to the suction arm 9 of the rotary suction drum 8 is carried, and a predetermined work 12 is fed to the work transfer path 11. With this configuration, it becomes a non-separable label sticking device.

Dust label 1 "which is the leading end side of non-separable label 1 from which label piece 1 'of a predetermined shape has been punched out.
Is wound sequentially around the core portion 14 via an appropriate feed roller 13 so that tension is applied to the entire non-separable label. The die-cut anvil roller 5 is of a known suction type for label suction, and the blade 6 of the die-cut roller 4 has a blade 6.
Is applied with a Teflon (registered trademark) coat to improve the separation of the adhesive surface 1b of the label piece 1 '. Further, the suction arm 9 of the rotary suction drum 8 can be reciprocated by a single structure, or a device having a plurality of the suction arms can be rotated synchronously with the die-cut roller 4 and the die-cut anvil roller 5 to increase the sticking ability. It is possible.

Now, the operation will be described. First, a tape-shaped non-separable label 1 wound around a roll is appropriately fed, and the non-separable label 1 is inserted so that the printing surface 1a faces the die-cut roller 4 and the adhesive surface 1b faces the die-cut anvil roller 5. The leading end side is led out to the core part 14 on the front side.

When the non-separator label 1 is pulled in by rotating the pair of rollers 4 and 5 by a known driving means (not shown) separately, the die cutting blade 6 protruding from the die cut roller 4 is formed. When the printing surface 1a of the non-separable label 1 is reached, the die-cutting anvil roller 5 and the receiving of the die-cut anvil roller 5 make a shape cut for die cutting. This shape cut is a cut in which the die cutting blade 6 is applied to the printing surface 1a side, and since the adhesive surface 1b is located on the back surface, the adhesive surface 1b is attached to this blade portion.
It is possible to cope with long-term cutting without directly applying the glue (adhesive) of b.

Thereafter, the label piece 1 'whose shape has been cut is
Is wound around the adhesive surface 1b by the suction action of suction air generated on the roller surface of the die-cut anvil roller 5, and is rotated at a predetermined angle. When the label piece 1 'comes to the discharge position 5a of the die-cut anvil roller 5, the suction surface 9a of the suction arm 9 of the rotary suction drum 8 which is adjacently rotated synchronously and faces the printing surface 1a located outward. Because of this, the label piece 1 ′ is forcibly separated from the roller surface by the suction action of the suction air applied to the suction arm 9, and the adhesive surface 1 b is inverted to support the outward exposure.

In this state, the suction arm 9 is moved to the suction drum 8
The workpiece 12 fed to the separate workpiece transport path 11 flows to a position transported by a predetermined angle due to the rotation of, so that the label piece 1 ′, which is supported by the suction arm 9 while showing the adhesive surface 1 b, is pressed. Then, label attachment to the wall surface of the work 12 is completed.

The structure of the suction arm 9 is such that the support shaft 9b has a joint structure of a double pipe connection as shown in FIG. 2, and the length thereof can be adjusted by adjusting screws 9c arranged at this connection portion. If the telescopic arm 15 is taken, the suction arm 9 and the work 12
Fine adjustment of the distance (distance) between the two, and the adjustment of the pressing pressure against the work.

Further, as in the other embodiment shown in FIG. 3, a non-tension type in which the blade portion provided on the die cut roller is a cut-out blade (straight blade) and is cut to a fixed size,
Basically, it is the same as the above embodiment. That is, the tape-shaped non-separable label 1 wound around a roll is appropriately fed out in the same manner as described above, and the printing surface 1a of the non-separable label 1 is directed to the die-cut roller 4, and the adhesive surface 1b is inserted toward the die-cut anvil roller 5, and cut off to the printing surface 1a. Blade 6 '
And a rotary suction drum 8 having a sticking suction arm 9 provided side by side at the discharge position 5a of the die-cut anvil roller 5, and a rotary unloading position of the suction arm 9. A work transport path for feeding the work 12 (the work portion is not shown because it is the same as that in FIG. 1).

However, in this embodiment, the non-separable label 1 inserted between the die-cut roller 4 and the die-cut anvil roller 5 is laid without tension on the label in order to cut the tip of the die-cut roller 4, and is positioned at a position before the roller 4. The auxiliary suction guide belt 16 for the label end is installed in parallel to a certain portion of the non-separable label, and the free end of the non-separable label end portion is reliably guided between the rollers 4 and 5. In this case, the structure of the suction guide belt 16 may be a simple structure using a roller for feeding a label and a suction belt or a simple endless caterpillar type silicon belt (not shown). It only has to lead between 4 and 5. The blade portion of the die-cut roller 4 is a straight cutting blade 6 'having a tape width.

Here, the roll-wound non-separable label 1 is fed out in the same manner as described above, and the printed surface 1a is directed toward the die-cut roller 4 and the adhesive surface 1b is directed toward the die-cut anvil roller 5. The die cut roller 4 is rotated to cut the non-separable label 1 with the release blade 6 '.
Since the adhesive surface 1b side is located on the back surface side from the printing surface 1a side, the adhesive of the adhesive surface 1b does not directly adhere to the blade portion.

The shape-cut label piece 1 ′ is wound around the adhesive surface 1 b by the die-cut anvil roller 5, and is rotated by a predetermined angle. When the label piece 1 'arrives at the discharge position 5a of the same roller, the suction arm 9 of the rotary suction drum 8 at the next stage comes into contact with the printing surface 1a, which is shifted outward, and the suction is separated. The label piece 1 'serves as a reversal support that exposes the adhesive surface 1b outward.

Further, similarly to the above, the suction arm 9 supporting the label piece 1 'is carried to a wall surface position of the work in the work transfer path by rotating the suction drum 8 by a predetermined angle (not shown), and the bell piece 1 is moved. ′ Is pressed against the wall surface of the work and the label is attached.

[0033]

As described above, in the non-separable label sticking apparatus of the present invention, the tape-shaped non-separable label is inserted so that the printing surface is directed to the die-cut roller having the blade and the adhesive surface is directed to the opposing die-cut anvil roller. Therefore, when the shape is cut (die-cut or released), the adhesive on the adhesive surface does not directly adhere to the blade by cutting from the printing surface. That is, the amount of glue adhering to the cutter can be significantly reduced as compared with the conventional method of directly cutting from the adhesive surface side,
Frequent cutter wiping work is also reduced, so-called cleaning times can be reduced, leading to a significant increase in efficiency.

Needless to say, in order to reverse the printing surface and the adhesive surface when cutting the non-separable label, label inverting means for temporarily inverting the adhesive surface to make the adhesive surface face up is required in attaching the label to the work. Is a simple mechanism that has a label suction action consisting of a rotary suction drum with a sticking suction arm that rotates synchronously with the die cut roller and the die cut anvil roller, without causing malfunction.
Reliable label reversal and transfer can be performed, and from this point, the sticking ability can be improved.

In this case, since the sticking suction arm is of a telescopic type in which the length of the arm can be changed, fine adjustment of the transfer distance (interval) between the suction arm and the work is easy, and pressing is performed according to the work. The pressure can be appropriately adjusted, and reliable sticking to various works can be performed.

Further, the label sticking apparatus of the present invention has an effect that the degree of freedom of the sticking position of a label-cut label without separator (non-separable label) is increased, and the restriction on the work position can be greatly eased.
