[Technical Field]

[0001] The present invention is a linerless label with a predetermined cutting position. from The present invention relates to a label cutting device that can cut out one label piece at the cutting position. [Background technology]

[0002] The so-called linerless label does not use a liner, and the cut position of the label changes depending on the amount of printing. Since it can be used for various products, the label disclosed in the following patent document There are also linerless labels in which label pieces of a fixed shape are continuous in the conveying direction, as shown in the figure.

[0003] In such linerless labels, the label is separated at the boundary between label pieces of a certain shape. If the cutting position is even slightly off, the shape of the label may differ. When bell pieces are issued and attached to products, the value of the products themselves is diminished. do. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-2441 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention is a new linerless label that can solve this problem. from , one piece Label cutting device that can cut the label piece at a predetermined position Place The objective is to provide [Means for solving the problem]

[0006] The present invention Use The linerless label is a label of a predetermined shape with one side being the printing surface and the other side being the adhesive surface. Piece A belt-shaped linerless label that is continuously connected in the conveying direction as one unit, A cutting margin is provided at the boundary between each of the label pieces in a direction perpendicular to the conveying direction, 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. It is a linerless label.

[0007] This means that even if the cutter's cutting position is slightly off, it will not affect the label piece of the specified shape. Therefore, even if the printed label is attached to a product, the product value will be diminished. That's not the case.

[0008] The cutting margin is provided with plane-symmetric notches in a direction perpendicular to the conveying direction. In the area sandwiched between the plane-symmetrical notches, a slit parallel to the conveying direction is formed. A plurality of such electrodes are provided in a direction perpendicular to the direction of the arrows.

[0009] As a result, adjacent label pieces are cut at the cutout portions that are plane-symmetrical. Even if the placement is slightly off, it will not affect the label piece of the specified shape. In the area, a plurality of slits parallel to the conveying direction are provided, and the approximately central portion of the slits is Since the sheet is cut in a direction perpendicular to the conveying direction, each slit is exposed on the cut surface. Therefore, when the issued label is affixed to the packaged product, the packaging of the product When the film is torn, the label strip is torn from the slit. Therefore, it is ideal as a label to be attached to packaged rice balls, for example.

[0010] The label cutting device according to the present invention is configured such that a plurality of label pieces are continuously connected in the conveying direction via notches in a direction perpendicular to the conveying direction. The width of the notch in the conveying direction is formed to a width that allows for deviation of the cutting position.

The cutter is operated at a timing when the cutting edge is cut.

[0011] This allows the label pieces to be separated by a , a width that allows for deviation of the cutting position of the cutter Since the linerless label is cut at the cutout portion, the label piece cut out from the linerless label always has a predetermined shape. [Effects of the Invention]

[0012] According to the present invention, a linerless label in which label pieces of a predetermined shape are continuously connected in the conveying direction is produced. Even if there is a label, the label is cut off by the cutting margin as the boundary between the front and rear label pieces in the conveying direction. The bell pieces can be cut off. Notch as for, Cut position Since a width is provided to allow for deviation, even if the cutting position is slightly off, it does not affect the cut label piece, which has the advantage of not causing any problems that would reduce the value of the product to which it is attached. [Brief explanation of the drawings]

[0013] [Figure 1] A plan view of a portion of a linerless label in which label pieces of a predetermined shape are continuously connected in the conveying direction. [Figure 2]FIG. 10 is a plan view of a label piece cut from the linerless label; [Figure 3] 3 is a schematic diagram of a label cutting device that issues the label strips of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] (Configuration of linerless label L) The linerless label L shown in Figure 1 has one side (front) as the printing surface and the other side (back) as the adhesive surface. The label strip LP having a predetermined shape is conveyed as a single unit to be attached to a product (not shown). The label piece LP is a continuous strip in the direction F. In other words, the label piece LP is a kamaboko-shaped At the boundary B between adjacent label pieces LP, A cutting margin CR is provided in a direction perpendicular to the conveying direction F, and the cutting margin CR in the conveying direction The width W is set to a width that allows for deviation of the cutting position of the cutter C, which will be described later, for example, 2 mm. It is being done.

[0015] In addition, the cutting margin CR is provided with a plane-symmetric notch N in a direction perpendicular to the conveying direction F, In the area of ​​the cutting margin CR sandwiched between the symmetrical notches N, a slit parallel to the conveying direction F is formed. A plurality of S are provided in a direction perpendicular to the conveying direction F. Specifically, the S are spaced at intervals of approximately 1 mm. There are multiple slits S, but these slits S are arranged so as not to overlap with the central end E of the cutout N. On the other hand, slits S are also formed in the linear portion of the label piece LP, which is formed in a direction perpendicular to the conveying direction F. Furthermore, the cutout N has a linear portion parallel to the direction perpendicular to the conveying direction F. In other words, the central end E of the cutout N forms a rectangle with the front and rear label pieces LP and the cutting margin CR. Furthermore, the cutouts N are formed at regular intervals for each label piece LP.

[0016] FIG. 2 shows a label strip LP cut from a linerless label L. 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 The left and right corners are also cut small, forming a shape similar to the cross section of a kamaboko (fish cake) with a plate. For example, when a label piece LP is attached to an isosceles triangle packaged rice ball, the upper left The right corner is designed so that it does not protrude from the triangular rice ball.

[0017] The slit S is formed so that when the label piece LP is attached to, for example, a packaged rice ball, When the packaging film is torn vertically, the label piece LP is torn along with the slit S. The slit S is torn vertically from the center end E of the notch N. The reason why the label piece LP is not overlapped with the edge E is to prevent the label piece LP from breaking off from the edge E. This is because the spacing between the slits S at the boundary portion B between the label pieces may be different from the spacing between the slits S formed elsewhere. Specifically, the spacing between the slits S at the boundary portion B between the label pieces is made narrower than in other portions. This makes it easier for consumers to tear the label pieces LP from an article to which the label pieces LP are affixed.

[0018] (Control operation of label cutting device 1) In FIG. 3, the label cutting device 1 includes a cutter C for cutting the linerless label L, It is located upstream of cutter C in the label transport direction and feeds linerless label L into cutter C. The conveying mechanism 2 includes a cutter C, and the conveying mechanism 2 and the cutter C are disposed between the conveying mechanism 2 and the cutter C. A sensor 3 detects the notch N, and a cutter is operated based on the notch detection signal of the sensor 3. and a control unit 4 that operates the .C.

[0019] The cutter C is of a known construction, for example, consisting of a movable blade that moves back and forth in a straight line and a fixed blade. However, the fixed blade may also be configured to reciprocate at the same time.

[0020] The conveying mechanism 2 includes a print head 20 and a linerless label L that is pressed against the print head 20. The print head 20 is configured with a platen roller 21 that conveys the linerless label L. The printing surface of the label L is in contact with the platen roller 21 side, and the adhesive side of the linerless label L, i.e., the adhesive side Therefore, the surface of the platen roller 21 is set so that the label is attached to the surface of the platen roller 21. A release agent is applied to the adhesive surface of the tape to prevent it from sticking.

[0021] The sensor 3 is composed of a light projector 30 that emits a beam and a light receiver 31 that receives the beam. This sensor 3 is preferably located at the center end of the notch N in FIG. The sensor 3 is attached at a position close to the center end E of the notch N in a state where it is floating above the linerless label L. In other words, the sensor 3 detects light that passes through the label piece LP at the center end E of the notch N.

[0022] The control unit 4 is composed of a microcomputer, and starts counting by the detection signal of the sensor 3. This soft timer starts when the notch N is detected by sensor 3. The timing starts from the moment the notch N reaches the cutting position of the cutter C. Specifically, it is programmed to type up as much as possible from the detection position of sensor 3. The travel time is calculated by dividing the distance the linerless label is transported to the moving blade by the transport speed of the linerless label. The control unit 4 is configured to time out the timer just before the time elapses. It is programmed to operate the movable blade of cutter C in the up position. The linerless label L is cut at a predetermined position within the cutting allowance CR in the notch N. In other words, the cutting is performed at a predetermined position within the width W of the cutting margin CR in the conveying direction. In the above, the control unit 4 determines the timing at which the sensor 3 detects the detection signal. The control unit 4 controls the drive of the cutter C based on the time. The label is fed for a preset length starting from the time when the detection signal is detected. The cutter C may be driven and controlled at that timing.

[0023] In FIG. 3, the linerless label L is attached to the roll receiving section 5 in a rolled state, and the linerless label L unwound from the label roll LR is fed to the pinch roller PR via multiple guide rollers GR1 and GR2, and is then fed to the platen roller 21 at a constant speed by the pinch roller PR.

[0024] The label cutting device 1 is configured to receive an input device for inputting information about an article to which a label piece LP is to be attached. In this case, the control unit 4 may be configured to receive the information of the product input by the input unit. Based on the information, the control unit 4 changes the cutting position within the cutting allowance CR in the notch N. The cutting position may be set downstream in the conveying direction, or may be set upstream in the conveying direction. It's okay to set it.

[0025] Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment. Other embodiments are possible within the scope of the claimed invention. [Explanation of symbols]
