Abstract

PURPOSE:To provide an improved adhesive free area between a label piece and its mount by a method wherein a label piece is peeled off, held temporarily on the lower surface of a label suction plate and attached to an object and, synchronously with the start of this attaching operation, a continuous label sheet is so controlled as to move only a short distance in the feeding direction. CONSTITUTION:A label piece 10 is printed by a thermal head 2, peeled off its mount at a portion of a label peeling plate 4 and held by suction on the lower surface of a label suction plate 5, which is then moved toward an object 16 to be labeled together with the label piece 10 held thereon. Simultaneously with this movement of the label suction plate, a platen 3 or mount take-up means 7 is activated by the control signal from a control circuit 21 to move a continuous label sheet 8 only an extremely short distance in the feeding direction, and then the label suction plate comes in the normal label piece attaching operation. In this way the rear end of the label piece 10 can be run off the label travel shifting end of the label peeling plate 4 with a small resistance to avoid improper label attachment.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking apparatus and a label sticking method, and in particular, the sticking of a label piece to an object to be stuck is considered to be a good separation between the label piece and the backing sheet during the label piece sticking operation. The present invention relates to a label sticking device and a label sticking method that can be favorably performed.

[0002]

2. Description of the Related Art Conventionally, as a sticking method of this kind of label sticking apparatus, there are various methods such as a so-called cylinder method, a cylinder jet method, an air blow method and the like.

The so-called cylinder system is a system in which a holding means for holding a peeled label piece by a vacuum suction action or the like is pressure-bonded to an object to be adhered by a cylinder or the like.

The so-called cylinder jet system is a system in which a holding means for holding a peeled label piece by a vacuum suction action or the like is moved to the vicinity of an object to be stuck by a cylinder or the like and then stuck by an air jet.

The so-called air blow method is a method of sticking a peeled label piece by an air jet in a state where it is held by a holding means by a vacuum suction action or the like.

[0006] In such a label sticking apparatus, the adhesive between the backing paper and the rear end of the peeled label piece is poor, and sticking mistakes on the sticking object are likely to occur.

An outline will be given based on FIGS. 3 to 7. Figure 3
FIG. 1 is a schematic view of a general label sticking apparatus 1, which has a printing mechanism, for example, a thermal head 2 for printing, a platen 3, a label stripping plate 4, and a label. It has a sticking machine 6 including a suction plate 5 and a mount winding machine 7.

FIG. 4 is a plan view of the label continuum 8, and FIG. 5 is an enlarged sectional view of the label continuum 8. The label continuum 8 has a structure in which a plurality of label pieces 10 are temporarily attached on a strip-shaped mount 9. In particular, as shown in FIG. 5, a release agent layer 11 made of a release agent or the like is formed on the mount paper 9, and an adhesive layer made of an adhesive agent (paste agent) or the like having a predetermined adhesive force is formed on the label piece 10. 12 is formed.

The label continuum 8 is fed from the supply unit 13 thereof, passes through the detector 14 and the transfer roll 15 to reach the thermal head 2 and the platen 3 and is printed with predetermined information. The label piece 10 is peeled from the mount 9 by turning at the label peeling plate 4.

As the transfer means for transferring the label continuum 8, any one of the transfer roll 15, the platen 3 and the mount take-up machine 7 can be employed singly, but these are driven in synchronization. It may be configured to do so.

The peeled label piece 10 is sucked and held on the lower surface by the vacuum suction action of the label suction plate 5, and is stuck on the stuck object 16 by moving the sticking machine 6 in the direction of the stuck object 16. To be done.

However, in the label sticking apparatus 1 having such a structure, as the peeling label piece 10 is gradually sucked and held by the label sucking plate 5, the sucking area is increased, so that the label sucking force is increased. Further, peeling the label piece 10 reduces the adhesive area between the label piece 10 and the backing sheet 9 and also reduces the force for feeding out the label piece 10, so that the label piece 10 moves forward (to the left in FIG. 3). However, it is difficult to completely peel the label piece 10 from the mount 9 even when the mount 9 is wound by the mount winder 7.

Therefore, as shown in FIG. 3 in particular, the rear end portion 10A of the label piece 10 is slightly attached to the backing sheet 9, and the label adsorption plate 5 or the sticking machine 6 is attached to the sticking object 16 along with the label piece 10. When moving to, there may be a sticking error such as incomplete sticking or inaccurate sticking.

That is, when a strong peeling force is required due to uneven application of the adhesive layer 12 of the label piece 10 or the release agent layer 11 of the mount 9, or when the label is cut in the production process of the label continuum 8. When it reaches 9 and the adhesive layer 12 part is embedded in the mount 9 through the release agent layer 11, it may be difficult to separate the mount 9 and the label piece 10.

Therefore, for example, as shown in FIG.
Despite the movement of the label suction plate 5 toward the adhered object 16, the label piece 10 is left behind on the mount 9 of the label peeling plate 4 and is not adhered to the adhered object 16 and remains on the converted mount 9. There is a problem of reattachment.

Alternatively, as shown in FIG. 7, the label piece 10
Even if the label sticker plate 5 moves in the direction of the pasted object 16 together with the label suction plate 5, the label piece 10 is pulled in the direction of the mount 9 and the suction position shifts, so that the label piece 10 is correctly pasted at a predetermined position of the pasted object 16. It may not be possible.

Regarding the problem of the above-mentioned sticking mistake,
The case of the cylinder method in which the label piece 10 is pressure-bonded to the adhered object 16 as the sticking means has been described, but the cylinder jet method in which the label piece is held and moved once in the direction of the stuck object and then stuck by the air jet Or, the same applies to various sticking means such as a sticking means of a method in which the label piece 10 is pressure-bonded to the sticking object 16 by a two-stage movement, or an air blow sticking means of sticking with an air jet.

Further, it goes without saying that a label sticking device having no printing mechanism as a label sticking device and having a function of simply sticking only the label piece 10 to the stuck object 16 has the same problem. Yes.

Further, in order to eliminate such a sticking error, after the label piece 10 is sucked, the label suction plate 5 or the label peeling plate 4 is once moved in a direction away from each other so that the mount 9 and the rear end portion of the label piece 10 are moved. Although a method such as forcibly separating from 10A is carried out, it is necessary to provide a moving mechanism for these label suction plates 5 or label peeling plates 4 in addition to the original label sticking mechanism, resulting in cost increase. There is a problem that the entire device becomes complicated.

[0020]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and when the label piece is moved in the direction of the object to be adhered, the separation from the mount sheet, that is, the breakage of the paste, is improved. It is an object of the present invention to provide a label sticking device and a label sticking method capable of performing a reliable label sticking operation while avoiding the above problems with a simple configuration.

[0021]

That is, the present invention focuses on moving the peeled label piece and the mount or the label continuum in association with the initial operation of the attaching means. The invention of claim 1 peels the label piece from the label continuum by transferring the label continuum in which a plurality of label pieces are temporarily adhered onto a strip-shaped mount by transfer means and turning only the mount. A label sticking device for temporarily holding a label piece and sticking it to a predetermined object to be stuck, wherein label holding means for temporarily holding the peeled label piece on its lower surface, and the held label piece is stuck to the sticking piece. An adhering means for adhering to the object, and a control means for controlling the transfer means so that the label continuum is slightly extended in the transfer direction in synchronization with the start of the adhering operation by the adhering means, A labeling machine, characterized in that it comprises.

A second aspect of the present invention is to transfer the label continuum, which is obtained by temporarily attaching a plurality of label pieces on a strip-shaped mount, by means of a transfer means and to turn only the mount to turn the label continuum from the label continuum. A label sticking method in which a piece is peeled off, and the label piece is temporarily held and stuck to a predetermined object to be stuck, and the label piece to be peeled off is temporarily held on the lower surface of the label holding means and held. A label sticking method characterized in that the transfer means is controlled so as to feed the label continuum in the transfer direction very slightly in synchronization with the start of the sticking operation by the sticking means for sticking the label piece to the pasted object. is there.

The length for feeding out the mount or the label continuum is at least the length at which the rear end portion of the label piece is temporarily attached to the mount and not more than the length of scraping between the label pieces. Is desirable.

[0024]

In the label sticking apparatus and the label sticking method according to the present invention, since the respective sticking apparatuses originally have the function of feeding out the label continuum or the mount, a simple control operation is required without adding new mechanical means. Only by this, it is possible to achieve the intended purpose with a simple structure and low cost.

That is, since the label continuum can be moved in the transfer direction in synchronization with the initial movement of the label holding means,
The resistance between the back end of the label piece still attached to the backing sheet and the backing sheet is reduced to ensure the peeling of the label piece from the backing sheet, and the label holding means keeps the label piece holding posture normally. The label sticking operation can be ensured.

[0026]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A label sticking device 20 according to an embodiment of the present invention will be described below with reference to FIGS. However,
The same parts as those in FIGS. 3 to 7 are designated by the same reference numerals, and the detailed description thereof will be omitted.

FIG. 1 is a schematic view of the label sticking device 20, FIG.
Is an enlarged view of a main part thereof, and the mechanical structure itself of the label sticking device 20 is the same as that of the conventional label sticking device 1,
The control circuit 21 as the control means is provided with the following functions.

That is, when the label suction plate 5 shown in FIG. 1 starts moving in the direction of the adhered object 16, the platen 3 or the mount winder 7 is driven at the same timing to feed the mount 9 in the transport direction, and The rear end portion 10A of the piece 10 is controlled so as to pass through the front end portion of the label peeling plate 4 together with the mount 9.

More specifically, as shown in FIG. 2, at least the length A at which the rear end 10A is temporarily attached to the mount 9.
As described above, the label continuum 8 or the backing sheet 9 is relatively transported in the downstream direction by a length that is equal to or less than the length B between the label pieces 10. The label piece 10 has a length C.

That is, the label piece 10 adsorbed and held on the lower surface of the label adsorbing plate 5 is attached together with the label adsorbing plate 5 by printing on the label piece 10 by the thermal head 2 and peeling at the portion of the label peeling plate 4. Object 16
At the same time, the platen 3 or the mount take-up machine 7 is driven by the control signal from the control circuit 21 to move the label continuum 8 by a slight distance in the transfer direction, and then the regular label strips. 10 Enter the sticking operation.

As the transfer means for this transfer, the label continuum 8 may be transferred by the platen 3 and the thermal head 2, or the mount winder 7 or the transfer roll 15 may be used.

Thus, the label piece 10 adsorbed on the label adsorbing plate 5 and temporarily held is the adhered object 16 of the applicator 6.
With the movement in the direction, especially the rear end 10A is relatively transferred together with the backing sheet 9 at the label peeling plate 4, the resistance between them is reduced, and the rear end 10A is moved to the label peeling plate 4. It is avoided that the part of the mount 9 is temporarily attached.

Therefore, the normal label sticking operation can be performed without the sticking mistake of the label piece 10 described with reference to FIGS. 6 and 7.

After the label attaching operation is completed, the label suction plate 5 returns to its original position, and printing, peeling,
Each operation of suction and sticking is performed, but since the label piece 10 having the length C is located on the front side of the tip of the label peeling plate 4, there is no problem in the printing operation.

However, when the next label piece 10 projects from the tip of the label peeling plate 4, the transfer means is reversed to control the label piece 10 to return to the normal printing position. You can also

It should be noted that the transfer (printing) speed for feeding out the label continuum 8 in the transfer direction is ideally the same as the moving (lowering) speed of the label suction plate 5, but in the present label sticking apparatus. Is higher than the transfer speed of the label continuum 8 and there is a difference between both speeds, but as described above, the label suction plate 5 moves at the same timing as the start of movement of the label suction plate 5. By feeding the continuous body 8 in the transport direction, this speed difference can be reduced and the resistance to the rear end portion 10A of the label piece 10 can be reduced, so that the intended purpose can be achieved.

As described in the description of the prior art, the present invention can be applied to any method such as a pressure bonding method or an air blow method as the sticking method of the label sticking apparatus, and the sticking operation is started in synchronization with the sticking operation. The label continuum may be fed out in the transfer direction.

[0038]

As described above, according to the present invention, the rear end portion of the label piece has a very small length remaining on the mount without adding a new mechanical structure to the structure of the conventional label sticking apparatus. By the simple control of feeding the label continuum or backing sheet by the same amount as the descending (pasting operation) of the sticking means such as the label suction plate (pasting operation), the label peeling plate of the label peeling plate with less resistance at the rear end of the label piece. It is possible to get over the tip for turning, and it becomes possible to avoid the pasting mistake as in the past.
