Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linerless label whose cutting position is determined, and a label cutting device capable of cutting out one label piece at the cutting position.

So-called liner-less labels, which do not use a liner, are often used for various products because the cut position of the label can be changed according to the amount of printing. There is also a linerless label in which shaped label pieces are continuous in the conveying direction.

With such a linerless label, the label must be cut at the boundary between label pieces that have a fixed shape. When attached to a product, there arises a problem that the value of the product itself is impaired.

JP-A-9-2441

An object of the present invention is to provide a new linerless label that can solve this problem, and a label cutting device that can cut the label at a predetermined position.

The linerless label according to the present invention is a band-shaped linerless label in which label pieces each having a predetermined shape and having a printing surface on one side and an affixing surface on the other side are continuously connected in the conveying direction as one unit. hand,
A cutting allowance is provided in a direction orthogonal to the conveying direction at the boundary between the label pieces,
In the liner-less label, the width of the cutting margin in the conveying direction is formed to a width that allows for deviation of the cutting position of the cutter.

As a result, even if the cutting position of the cutter deviates to some extent, the label piece having the predetermined shape is not affected, so even if the printed and issued label piece is attached to the product, the commercial value of the product is not lost. .

Further, the cutting allowance is provided with a plane-symmetrical notch in a direction perpendicular to the conveying direction, and a slit parallel to the conveying direction is formed in a region sandwiched between the plane-symmetrical notches. It is characterized in that a plurality of the electrodes are provided in a direction perpendicular to the direction.

As a result, adjacent label strips are cut at the plane-symmetrical notch portions, so even if the cutting position is slightly deviated, the label strips having the predetermined shape are not affected. In addition, a plurality of slits parallel to the conveying direction are provided in the region sandwiched between the plane-symmetrical notches, and the substantially central portions of these slits are cut in a direction perpendicular to the conveying direction. will expose each slit. Therefore, when the issued label piece is attached to a packaged product, the label piece is torn from the slit when the packaging film of the product is torn. Therefore, it is most suitable as a label to be attached to packaged rice balls, for example.

A label cutting device according to the present invention is a linerless label cutting device in which a plurality of label pieces are continuously connected in the conveying direction through notches in a direction orthogonal to the conveying direction,
a cutter for cutting the linerless label;
a transport mechanism arranged upstream of the cutter and transporting the linerless label to the cutter;
a sensor disposed between the conveying mechanism and the cutter for detecting the notch;
a control unit that operates the cutter based on the notch detection signal of the sensor,
The controller operates the cutter at the timing when the notch detected by the sensor reaches the cutting position of the cutter.

As a result, the linerless label is cut at the notch portion as a cutting allowance provided between the label pieces, so that the label piece cut out from the linerless label always has a predetermined shape. .

According to the present invention, even in a liner-less label in which label pieces of a predetermined shape are continuously connected in the conveying direction, the label pieces can be cut with a cutting allowance as a boundary portion between label pieces in the conveying direction. can be disconnected. Moreover, since the cutting margin is provided with a width that allows deviation, even if the cutting position is slightly deviated, the cut label pieces are not affected, so that the value of the attached label is reduced. It has the advantage of not causing any problems.

(Structure of linerless label L)
The liner-less label L shown in FIG. 1 is a label piece LP of a predetermined shape having one side (front side) as a print side and the other side (back side) as an attachment side as a unit to be attached to a product (not shown). It is a band-shaped one continuously connected in the conveying direction F. In other words, the label piece LP is a liner-less label having a kamaboko shape. A boundary portion B between adjacent label pieces LP is provided with a cutting allowance CR in a direction perpendicular to the conveying direction F. A width W of the cutting allowance CR in the conveying direction is determined by a cutter C described later is formed to have a width of 2 mm, for example, which allows deviation of the cutting position.

Further, the cutting allowance CR is provided with a plane-symmetrical notch N in a direction perpendicular to the conveying direction F, and the region of the cutting allowance CR sandwiched between the plane-symmetrical notches N has a A plurality of slits S are provided in a direction orthogonal to the transport direction F. Specifically, a plurality of slits S are provided at intervals of approximately 1 mm, and the slits S are provided so as not to overlap the central end portion E of the notch N. As shown in FIG. On the other hand, the slit S is also formed in the linear portion of the label piece LP formed in the direction orthogonal to the conveying direction F. As shown in FIG. Furthermore, the notch N has a straight portion parallel to the direction orthogonal to the transport direction F. That is, the center end E of the notch N forms a rectangle with the front and rear label pieces LP and the cutting allowance CR. Also, the notches N are formed at regular intervals for each label piece LP.

FIG. 2 shows one label piece LP cut from the linerless label L. FIG. In this figure, the upper left and right corners of the label piece LP are cut into arcs with a radius of approximately 1 cm, and the lower left and right corners are also cut into small pieces, forming a shape like the cross section of a kamaboko with a plate. there is For example, when the label piece LP is attached to an isosceles triangular packaged rice ball, the left and right corners of the upper portion are prevented from protruding from the triangular rice ball.

The slit S is formed so that when the label piece LP is attached to, for example, a wrapped rice ball and the rice ball packaging film is torn in the longitudinal direction, the label piece LP is also torn in the longitudinal direction from the slit S. The reason why the slit S is provided so as not to overlap the center end E of the notch N is to prevent the label piece LP from being broken from the end E. It should be noted that the interval between the slits S at the boundary portion B between the label pieces and the interval between the slits S formed elsewhere may be different. Specifically, the interval of the slit S formed at the boundary portion B between the label pieces is narrowed compared to other portions. This makes it easier for the consumer to tear the label piece LP in the article to which the label piece LP is attached.

(Control operation of label cutting device 1)
In FIG. 3, the label cutting device 1 includes a cutter C that cuts the linerless label L, a transport mechanism 2 that is arranged upstream of the cutter C in the label transport direction and feeds the linerless label L to the cutter C, and a transport mechanism. 2 and the cutter C to detect the notch N formed in the linerless label L; , is equipped with

The cutter C has, for example, a well-known configuration including a movable blade that reciprocates linearly and a fixed blade, but the fixed blade may also be configured to reciprocate at the same time.

The transport mechanism 2 includes a print head 20 and a platen roller 21 that presses the linerless label L against the print head 20 and transports it. The sticking side of the linerless label L, that is, the adhesive surface side is set so as to contact the roller 21 side. Therefore, the surface of the platen roller 21 is coated with a release agent so that the adhesive on the label sticking surface does not stick.

The sensor 3 has a well-known structure composed of a light projector 30 for emitting a beam and a light receiver 31 for receiving the beam. This sensor 3 is preferably mounted in a position close to the center end E of the notch N in FIG. In other words, the sensor 3 detects light passing through the label strip LP at the central edge E of the notch N.

The control unit 4 is composed of a microcomputer and has a soft timer that starts timekeeping with a detection signal from the sensor 3 . This soft timer is programmed to start timing when the notch N is detected by the sensor 3 and to start up just before the notch N reaches the cutting position of the cutter C. Specifically, it is configured so that the time is up just before the lapse of the movement time obtained by dividing the conveying distance of the linerless label from the detection position of the sensor 3 to the movable blade by the conveying speed of the linerless label. The controller 4 is programmed to operate the movable blade of the cutter C when the timer times out. As a result, the linerless label L is cut at a predetermined position within the cutting allowance CR in the notch N. As shown in FIG. In other words, the cutting is performed at any predetermined position within the width W of the cutting margin CR in the conveying direction. In the above description, the controller 4 drives and controls the cutter C according to time starting from the timing when the sensor 3 detects the detection signal. However, the control unit 4 may drive and control the cutter C at the timing when the label is conveyed by the preset label length, starting from the timing when the sensor 3 detects the detection signal.

In FIG. 3, the liner-less label L is attached to the roll receiver 5 in a rolled state, and the liner-less label L fed out from the label roll LR is passed through a plurality of guide rollers GR1 and GR2. It is sent to the pinch roller PR, and is sent to the platen roller 21 at a constant speed by the pinch roller PR.

Note that the label cutting device 1 may be configured to have an input unit for inputting information on the article to which the label piece LP is attached. In this case, the control unit 4 changes the cutting position within the cutting allowance CR in the notch N based on the article information input by the input unit. Specifically, the control unit 4 may set the cutting position downstream in the transport direction, or may set the cutting position upstream in the transport direction.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and other embodiments can be adopted within the scope of the invention described in the claims.
