Abstract

PURPOSE:To make a label attaching angle accurate even in the case of the travel speed of a long sheet being high or the long sheet being thin with small strength by providing an air discharging process of blowing air to a label in the slightly attached state to a mount tape so as to separate the label completely from the mount tape. CONSTITUTION:In a device frame 1, the tip of a separating plate 9 and the nozzle tip of an air discharge nozzle 4 are disposed in a position immediately in front of a position where a long sheet 11 comes in contact with a guide roller 12. When the control part of a label attaching device receives a command signal for attaching a label 10, a label tape is transferred into a specified position by the rotatory-driving of a drive roller 6, and a signal for opening a solenoid valve for the fixed time is outputted from the control part so as to feed air to an air discharge nozzle 4 through an air pipeline 20. The air is discharged from the air discharge holes 17 of an air discharge plate 18, and the air is blown to the label to separate the label 10 completely from a mount tape 8. The attaching angle of the label 10 can be thereby made accurate.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a labeling method and apparatus applicable to a long sheet running at a high speed and a long sheet which is very thin and easy to cut. In particular,
Long-sheet manufacturing and processing equipment such as offset printing machines, gravure printing machines, coating machines, paper manufacturing machines, and plastic sheet manufacturing machines The present invention relates to a label sticking method and device for sticking a label serving as a mark to an end portion in the width direction of a long sheet for the purpose of allowing visual judgment from the outside.

[0002]

2. Description of the Related Art In a long sheet manufacturing and processing apparatus such as an offset printing machine, a gravure printing machine, a coating machine, a papermaking machine, and a plastic sheet manufacturing machine, the quality check of a product called manufacturing condition determination at the first stage of manufacturing. The manufacturing conditions are repeatedly adjusted. After the production conditions are set, non-defective products are produced.However, in these production and processing devices, the long sheet after the production and processing is usually wound around the core of a paper tube or the like. It is not possible to determine where the product is good. Therefore, as a mark, a label is inserted and attached to the end portion of the long sheet in the width direction.

Further, when there is a defect such as a seam in a raw sheet which is a long sheet of raw material during the manufacturing process, a defective product is formed in that portion, so that a label is inserted and stuck as a mark or manufactured. It is also possible to insert and attach a label as a mark of the scale for each fixed length of the long sheet after processing. In addition, the manufacturing and processing conditions may be changed while the manufacturing and processing are performed for the purpose of prototyping, in which case a label may be inserted and attached as a mark for the purpose of ascertaining which part of the long sheet was under which condition. Be seen. For various purposes such as the above, a label is inserted and attached to a long sheet.

[0004] It is usual that the operator of the manufacturing and processing apparatus manually inserts and attaches the label to the long sheet as described above, but in that case, it takes some time before the insertion and attachment, so that the marker can be used. Since the error between the actual position of the label and the position where the label should be originally inserted and attached becomes large, the load of the quality check work in the subsequent process becomes large. Also,
When removing defective products, there was a problem that the loss was large because the product was discarded more than necessary in anticipation of safety. Furthermore, manually inserting and pasting labels on long sheets is not a small burden on the operator of the manufacturing and processing equipment, which is subject to a lot of work. Working close to the processing equipment was very dangerous.

Therefore, a device for automatically inserting and pasting a label has been considered, which is disclosed in JP-A-59-74040 and JP-A-53-53.
1917, Jikkou Sho 52-36557 and the like. FIG. 8 is a diagram showing the configurations of these conventional label sticking apparatuses. The touch roller 21 is used in the label sticking apparatus shown in FIG. In FIG. 8, the label tape 14 having the adhesive label 10 attached on the mount tape 8 made of release paper is set in the label tape supply unit 3 in a winding form. When the mount tape 8 is driven by the drive roller 22 in the direction in which the mount tape 8 is wound up by the mount tape winding section 23, the label 10 is peeled off by the peeling plate 27, but the label tape 10 is slightly peeled off on the mount tape 8.
It will stop and will be in the standby state. When the automatic label sticking apparatus receives a command signal for sticking a label, the touch roller 21 moves in parallel, and the sticking surface of the label is pressed against the running long sheet to insert and stick the label. Further, there is also known a label sticking device of a system in which a label peeled off by a peeling plate is held at one end by a method such as suction, and thereafter, high pressure air is blown by an air blow or the like to stick to a long sheet or the like.

With such a label sticking device, the sticking position is accurate, the work load is reduced, and the danger associated with the work can be avoided. However, in such a conventional label sticking device, when the traveling speed of the long sheet is high, the success rate of insertion and sticking becomes poor, and the label is not stuck to the long sheet or is bent and stuck. However, there was a case where the label could not be confirmed from the outside when the product was wound up because the label was hidden inside because it could not be affixed to the correct position on the edge of the long sheet.

If the long sheet is thin and not strong enough, the long sheet is cut by the inserting and pasting operation of the label, the production is interrupted, and much time and materials are wasted before the production is restarted. There was a problem such as. In addition, in a label sticking device of the type that holds by suction, a suction mechanism and a moving mechanism of a suction holding table are required to completely peel the label from the release paper, which not only complicates the device configuration and operation. However, the label was not completely peeled off, and when the high-pressure air was blown, the label was often caught on the release paper.

[0008]

In the above prior art, the label inserting and sticking operation is an operation of pressing the peeled label against the long sheet by the touch roller, and the strength of the long sheet is sufficient. Moreover, the reliable operation is performed only when the traveling speed is low. However, when the strength of the long sheet is not sufficient or the traveling speed is high, the conventional label sticking apparatus cannot be applied because it cannot obtain reliability. In addition, in the method of sucking and holding the label and blowing and sticking it with high-pressure air, not only is the device configuration and operation complicated,
After all, I didn't get the reliability. Therefore, there is only a method in which a person manually inserts and affixes the tape, and there is a problem that the position of the display label is displaced from the position of the long sheet to be indicated, and the work is dangerous. .

Therefore, the problem to be solved by the present invention is to perform a reliable and reliable operation even when the length of the long sheet is thin and the strength is insufficient, and when the running speed of the long sheet is high. An object is to provide an automatic labeling method and device.

[0010]

The above object can be achieved by the present invention described below. That is, according to the first aspect of the present invention, in order to drop the label on the long sheet immediately before the running long sheet comes into contact with the guide roller, the adhesive tape is applied to the release surface of the mount tape made of release paper. The label is attached by the transfer process of transferring the label tape in which a plurality of labels are regularly arranged and attached on the mount tape by the adhesion of the adhesive surfaces, the peeling process of peeling the label from the mount tape along with the transfer of the label tape, and the peeling process. And a slight amount of the label is attached to the mount tape, and air is blown to the label to completely remove the label from the mount tape. The second aspect of the invention is an adhesive surface of a label that is adhesively processed on the release surface of a mount tape made of release paper to drop the label on the long sheet immediately before the running long sheet comes into contact with the guide roller. A plurality of labels are regularly arranged on the mount tape to transfer the label tape attached and the peeling means for peeling the label from the mount tape as the label tape is moved, and the peeling means for peeling the label. A label sticking device having air ejecting means for blowing air onto the label to slightly separate the label from the mount tape while the label is slightly stuck to the mount tape.

FIG. 1 is a side view of the label sticking apparatus of the present invention. In FIG. 1, 1 is a device frame, 2 is a mount tape winding unit, 3 is a label tape supply unit, 4 is an air discharge nozzle, 5 is a nip roll, 6 is a drive roll, 7 is a tape guide roll, 8 is a mount tape, 9 is a peeling plate, 10 is a label, 11 is a long sheet, 12 is a sheet guide roll, 13 is a label detection sensor, and 14 is label tape winding. FIG. 2 is a perspective view of the label sticking device of the present invention. In FIG. 2, 1 to 9 are the same as those in FIG. 1, 17 is an air discharge nozzle hole, 18 is an air discharge nozzle plate, 19 is a motor, and 20 is an air pipe.

1 and 2, the apparatus frame 1 includes a mount tape take-up unit 2, a label tape supply unit 3, an air discharge nozzle 4, a nip roll 5, a drive roll 6, a tape guide roll 7, and a peeling plate 9. Label detection sensor 1
3, motor 19 and the like are attached. The transfer means in this example includes a nip roll 5, a drive roll 6, a label detection sensor 13, a motor 19, a motor driver (not shown), a controller (not shown), and the like. Further, the peeling means in this example is composed of the peeling plate 9 and the like.

Further, an air discharge nozzle hole 17 is opened in the surface of the air discharge nozzle plate 18 of the surface of the air discharge nozzle 4 facing the label 10. Further, one end of the air pipe 20 is connected to the air discharge nozzle 4, and the air pipe 2
Reference numeral 0 is connected to a high pressure air source via a solenoid valve (not shown) and an air pressure control valve (not shown). The air discharge means in this example includes an air discharge nozzle 4, an air pipe 20, an electromagnetic valve (not shown), an air pressure control valve (not shown), a high pressure air source (not shown), and the like.

The sheet guide roll 12 is a printing machine,
A guide roll for a long sheet in a long sheet processing device such as a coating device, which is selected from guide rolls at a position after final processing and at a position before being wound. As shown in FIG. 1, the apparatus frame 1 is installed so that the tip of the peeling plate 9 and the tip of the air discharge nozzle 4 are arranged at a position immediately before the long sheet 11 contacts the sheet guide roll 12. . Further, the label tape take-up 14 is a label tape in which a plurality of labels are regularly arranged and affixed to the mount tape 8 because the adhesive surface of the label that has been adhesively processed is attached to the release surface of the mount tape 8 made of release paper. It is in a state of being wound around the core.

The operation of the label sticking apparatus of the present invention having the above structure will be described. Label tape winding 14
Has a structure in which its core portion can be freely attached to and detached from the shaft of the label tape supply unit 3. In the attached state, the label tape take-up 14 is rotated by the shaft of the label tape supply unit 3 so that A predetermined back tension acts on the paper tape 8 to prevent the label tape from loosening. The label tape passes from the label tape supply unit 3 to the mount tape winding unit 2 via the tape guide roll 7, the tip of the wedge-shaped peeling plate 9, the drive roll 6 and the nip roll 5, and is wound there. The mount tape 8 sandwiched between the drive roll 6 and the nip roll 5 is transferred by the rotational drive of the drive roll 6.

That is, the label tape is transferred by the rotational drive of the drive roll 6, and the label 10 is peeled off at the wedge-shaped tip of the peeling plate 9 by the movement. The principle that the label 10 is peeled off at the tip of the wedge shape is that the adhesive force of the label 10 to the mount tape 8 and the rigidity force of the label 10 to maintain its shape are (adhesion at the tip of the wedge shape). This is because (force) <(rigidity force) is established.

The transfer amount of the label tape is controlled by the position of the label detected by the label detection sensor 13, and the label 10 is slightly attached to the mount tape at the tip of the peeling plate 9 and the label tape is attached. Is stopped. As the label detection sensor 13, an optical sensor having a light emitting / receiving unit such as an optical fiber sensor can be used, whereby the mount tape 8 and the label 10 can be used.
The position of the label 10 can be detected by a method such as detecting a difference in optical reflectance at the edge of the label 10 or detecting a pattern of the label 10.

When the control section (not shown) of the label sticking apparatus receives the command signal for sticking the label, the label tape is transported to a predetermined position by the rotational drive of the drive roll 6. Next, a signal for opening a solenoid valve (not shown) for a certain period of time is output from the control unit, and a high pressure air source (not shown), a pressure control valve (not shown), and air that has passed through the solenoid valve is connected to the air pipe. 20 to the air discharge nozzle 4, and the air discharge plate 18
Air is ejected from the air ejection hole 17 of the above, and air is blown to the label 10 to completely peel the label 10 from the mount tape 8. The above repetition is the basic operation of the label sticking apparatus of the present invention.

The command signal for sticking the label is obtained by the operator of the printing press or the like pressing the sticking command button switch. Alternatively, when an operator of a printing machine or the like wants to stick the label 10 to a predetermined length of a long sheet instead of pressing the sticking command button switch, a printed matter inspection device, a paper splicing detector, etc. When it is desired to paste the output signals of the devices, the measuring devices and the output signals of those devices can be input to the control unit of the label sticking device and used as command signals.

FIG. 3 is a diagram showing a process of attaching a label to a long sheet by the label attaching apparatus of the present invention. In FIG. 3, 4 is an air discharge nozzle, 6 is a drive roll, 8 is a mount tape, 9 is a release plate, 10 is a label,
Reference numeral 11 is a long sheet, 12 is a sheet guide roll, and 13 is a label detection sensor. A process of attaching the label to the long sheet in the above configuration will be described.
FIG. 3A is a diagram showing a transfer process. In FIG. 3A, the label tape is transported together with the mount tape 8 sandwiched by the nip roll 5 and the drive roll 6. The label detection sensor 13 monitors whether the label 10 on the label tape has reached a predetermined position.

FIG. 3B is a view showing a state in which the label tape is stopped at a predetermined position. In FIG. 3B, the control unit stops the transfer in response to the detection signal output by the label detection sensor 13 when the label 10 on the label tape has reached a predetermined position. Label 10
The label is peeled by the peeling process of peeling from the mount tape 8 as the label tape is transferred, and the label is slightly attached to the mount tape. That is, the transfer is stopped, and it is in a standby state for the next air discharge process. In this figure, the label detection sensor 13 is installed so as to detect the edge of the label two before the label 10 to be peeled off. However, the label detection sensor 13 is peeled off by an optical fiber sensor or the like capable of installing a detector in a narrow space. The label 10 may be installed so as to detect the edge of the label 10. If so installed, the stop position of the label 10 to be peeled off becomes more accurate.

FIG. 3C is a diagram showing an air discharge process. In FIG. 3C, the air discharge nozzle 4 is labeled 1
0 is blown with air to completely peel the label 10 from the mount tape 8. The peeled label 10 is a long sheet 1
1 and is transferred together with the long sheet 11. The air discharge nozzle 4 blows air immediately after the standby state described above.

In FIG. 3D, the label 10 is a long sheet 11
It shows the process of completely sticking to. The label 10 taken on the long sheet 11 is the sheet guide roller 1 immediately behind it.
2 and the long sheet 11 are transferred to the long sheet 11
The sheet guide rollers 12 sandwich and apply pressure to bond the sheets, and the sheets are completely attached to the long sheet 11.
When the label 10 is attached to the long sheet 11 in this manner, the process returns to FIG. 3A again and is repeated.

FIG. 4 is a diagram showing the positional relationship between the label 10 and the air discharge nozzle in the standby state. In FIG. 4, 4 is an air discharge nozzle, 8 is a mount tape, 9 is a peeling plate, and 10 is a label. In the label peeling mechanism described above, a slight error range may be recognized at the label stop position. 4 (a), 4 (b), and FIG.
(C) shows the error range of the stop position of the label. The cause of such an error is the adhesive strength of the adhesive of the label 10, the stop accuracy of the motor 19, the slack of the mount tape, and the like, and it is possible to implement the error with extremely high accuracy. In the above label sticking device, the error range of the stop position as shown in FIG. 4 can be allowed. This is not acceptable in the label sticking apparatus of the type described in the prior art, in which air is blown out after the label is sucked and held, and in the case of FIG. 4A, the upper part of the label is caught by the peeling plate, and In the case of (c), there is a problem that the suction plate is too far away from the label to suck.

In the label sticking apparatus of the present invention, since the label 10 is not sucked and only air is blown,
There is no problem in the above-mentioned related art, and an error range of about 2 mm can be allowed as the label stop position accuracy. Further, the most unfavorable stop position of the label 10 is in the case of FIG. 4A, in which case the label 10 is firmly attached to the mount tape 8 with an adhesive and is extremely difficult to peel off. In such a case, as shown in FIG. 1, the air discharge nozzle may be installed on the upper part of the label 10 so that air is blown from the upper part.

Further, in this example, there is no label holding mechanism after peeling, and therefore the label may drop without being picked up by the long sheet 11 at the same time as peeling. In that case, the label 10 also has a long length. Since it is sandwiched between the sheet 11 and the sheet guide roll 12, reliable label sticking can be performed. Therefore, the installation position of the label sticking device should be as close as possible to the contact portion between the long sheet 11 and the sheet guide roll 12.

FIG. 5 is a view showing the structure of a label tape used in the label sticking method and apparatus of the present invention. In FIG. 5, 8 is a mount tape, 10 is a label, and 14 is a label winding. The mount tape 8 is a paper tape having at least one surface that has been subjected to release processing such as silicone resin coating, and the release surface is subjected to one-side adhesive processing so that the adhesive surface of the label 10 is fitted. A plurality of labels 10 are arranged and attached to the mount tape 8 at regular intervals, which is called a label tape. Label tape winding 14 is a state in which the label tape is wound around a core such as a paper tube.

FIG. 6 is a view showing the structure of a label used in the label sticking method and apparatus of the present invention. 1 in FIG.
Reference numeral 0 is a label, and 15 is an adhesive coating portion. As shown in FIG. 6, the adhesive coating portion 15 of the label 10 may be the entire one side of the label 10, or may be a part of the one side of the label 10. By making the adhesive coating portion 15 a part of one side of the label 10, the label 10 is attached to the left and right ends of the long sheet 11 in the direction perpendicular to the traveling direction, and the adhesive coating portion 15 is provided on the outside. The non-existing portion can be exposed so that the outer portion of the label 10 does not cause unnecessary adhesion and trouble.

FIG. 7 is a view showing a rolled product obtained by winding the long sheet 11 to which the labeling method and apparatus of the present invention are applied. In FIG. 7, 10 is a label and 16 is a rolled product. In FIG. 7, the label 10 is attached to a plurality of display-required locations so that the position can be visually confirmed from the side surface of the rolled product 16. When the label sticking method and apparatus of the present invention are applied, the situation of the long sheet 11 inside the roll-up product 16 in the state of the roll-up product 16 is output from the side surface of the roll-up product 16 as described above. It can be known by the label 10 on the screen.

Further, in FIG. 7, the label 10 protruding from the side surface is shown, but the label 1 is not always necessary.
It is not necessary to output 0 from the side surface, and the label 10 may be attached to the central portion of the long sheet 11 instead of the left and right end portions depending on the purpose and application of attaching the label. According to the labeling method and apparatus of the present invention, the label 10 can be attached at any position in the traveling right angle direction, and the label 10 can be attached at any position in the traveling direction depending on the attachment timing. It is possible.

Although the present invention has been described above based on the embodiment, the present invention is not limited to this embodiment, and the present invention may be applied to the gist and technical idea of the present invention. Needless to say, it is included in. For example, when a plurality of types of labels are to be selectively used and attached depending on the difference in defect content, etc., a large number of the label attaching devices of the embodiment may be arranged, but a printing mechanism such as a stamp is added to the label attaching device of the embodiment. Then, the defective content can be printed and then the label can be attached, which is also included in the present invention.

In the embodiment, the label is peeled by the peeling process of peeling from the mount tape along with the transfer of the label tape, and the label is slightly attached to the mount tape, and the transport is stopped. It has been described that the standby state for the air discharge process of is entered. However, when the transfer or stop operation is slow, air is discharged by the air discharge process during the transfer, the transfer is stopped after that, and the operation speed can be improved by waiting for the next sticking command. . Further, in the example, the label sticking device is installed at a position on the sheet guide roll,
If it is placed on the nip roll of a processing machine such as a printing machine, the pressure bonding will be strong and the label can be adhered to the long sheet very reliably.

If a mechanism for stopping the movement of the long sheet in the direction perpendicular to the traveling direction is attached to the label sticking apparatus, the label sticking apparatus can be moved to an appropriate position even when the width of the long sheet changes depending on the item. it can. The mechanism may be manual or automatic, and a structure in which a movement stopping mechanism is added to such a labeling device is also included in the present invention. Further, as described a little in the embodiment, it is also possible to combine the label sticking device with an on-board defect inspection device or the like and use it as a label sticking portion of a system for automatically performing the process from the defect detection to the label sticking.

[0035]

According to the present invention, not only when the running speed of the long sheet is low or when the long sheet is thick and strong, but also when the running speed of the long sheet is high or the long sheet is Even when the strength is thin and the strength is small, the force acting on the long sheet at the time of attaching the label is extremely small because the label is dropped, and the sheet is not cut and the reliability is high. When the label is inserted and attached, the label is sandwiched between the guide roller and the long sheet at almost the same time and pressure-bonded to the long sheet, so that the label attachment position angle is extremely accurate. As a result, it is possible to convert the manual work that cannot be applied by the conventional tape sticking method and device into a device, and contribute to the improvement of safety, work load reduction, reliability and the like. Further, according to the label sticking method and apparatus of the present invention, it is possible to stick the label not only on the left and right end portions of the long sheet in the direction perpendicular to the traveling direction but also on the central portion.
