2. Description of the Related Art Conventionally, in a production process of performing printing on a web such as a roll of paper, an inspection process as a post process,
In order to make it possible to observe the defect state from the side and to accurately remove the defect, it has been practiced to attach a defect indication tape to the end of the web. In this case, the color of the instruction tape is changed to identify various types of defective contents, or the defective contents are printed with characters or marks.
In some cases, an instruction tape was used. However, when the selection and identification of these failures, the recording of the number of failure meters, etc. are also combined, it is difficult to perform them artificially because there are many marks and other types, and the mechanism is complicated even if it is performed mechanically There was a problem.

[0003] As an improved technique, a method of instructing where a defect is present by automatically attaching a magnetic tape in combination with an inspection device or the like is also used. However, the defect indicating tape in this case simply indicates the defect position, and the defect information of the defect content, such as the defect start position, the end position, and what kind of defect is not added, so When proceeding through
In some cases, the winding direction changes each time, making it difficult to determine which side of the defective instruction tape position has a defective portion.

[0004] For example, FIG. 7 is a diagram showing a method of adding defect information using a magnetic tape. In a process such as printing, the web 20 flows in the traveling direction of an arrow shown by a thick line. FIG. 7 (A) shows a case where 22 occurs.
As described above, the defective position indicating tapes 31b, 31e, 32b, and 32e are attached to the start and end of the defect. on the other hand,
When removing the defect or the like in the winding process in which the defect or the like has occurred in the inspection process, the web flows in the opposite direction as shown by the arrow as shown in FIG. The end has the opposite relationship to the printing process. In the case of such a simple process as printing → rewind inspection, the position of a defect or the like may still be recognized,
If a plurality of steps are performed before the inspection step, it becomes extremely difficult to recognize the position of a defect or the like, and a situation may occur in which the non-defective part 21g is erroneously recognized as a defective part and removed. Therefore, in the defect indication method using a magnetic tape,
A device or a form for storing which side the defective portion exists is required.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a defect information adding apparatus using a defect position indicating tape capable of storing information according to the present invention will be described.
This will be described with reference to the drawings. FIG. 1 is a diagram showing an outline of the defect information adding device. In the drawing, reference numeral 10 denotes a processing device such as a printing machine, 11 denotes a paper feeding unit of the web 20, 14 denotes a web discharging unit, and 23 denotes a wound semi-finished product. When the processing device is a printing machine, the web passes between the printing plate cylinder 12 and the printing impression cylinder 13 and is printed, and then becomes a semi-finished product via a drying device (not shown). The defect information adding device of the present invention is a device for adding defect information to such a semi-finished product, and writes defect information on a defect instruction tape composed of a non-contact IC tag, and attaches the instruction tape to a web. The winding length is measured and calculated by a winding length measuring device, data of the defective position indicating tape is read, and further writing and rewriting are performed.

The defect information adding apparatus according to the present invention comprises a data writing section 1, a tape sticking section 2, a winding length measuring instrument 3, a data reading / writing section 4, an arithmetic unit 5, and preferably dedicated data. And a rewriting unit 6. The data writing unit 1 and the tape attaching unit 2 are installed in the vicinity of a winding unit where processing such as printing is completed and the final state of the semi-finished product can be easily observed. The data writing unit 1 and the tape attaching unit 2 may be configured as a substantially integrated device. Also, the winding length measuring device 3, the data reading / writing unit 4, the arithmetic unit 5, and the data rewriting unit 6 are usually located at the final winding portion further downstream of the processing device. Although shown in FIG. 1 as a separate configuration, they can also be configured as a substantially integrated device except for the data rewriting unit 6.

FIG. 2 is a diagram showing a relationship between the defect information adding device and a semi-finished product having a defective portion. The printing plate cylinder and the like are omitted. In the figure, reference numeral 20 denotes a take-up web as a product, which indicates continuous paper from the paper feed unit 11 to the paper discharge unit 14. Since the web-shaped continuous paper naturally undergoes printing and other processing, it flows through the processing apparatus bent as described above, but is simplified and shown in a straight line in FIG. What is enlarged and shown in the oval of FIG. 2 shows a defect state in the vicinity of the paper discharge unit during the processing. If a defect 21 or 22 occurs on the web, the defect position indicating tapes 31b, 31e, and 32 are provided at the start point and the end point of the defect occurrence part.
The device of the present invention uses a non-contact IC tag capable of storing information on the defect position indicating tape, and records the content of the defect on the indicating tape when a defect is detected, and manages the defect. Is what you do.

The data writing unit 1 writes a defect ID, a defect name, and defect start information on a defect position indicating tape when the detection of a defect or the like is started by the inspection device or visually, and newly starts the detection when the detection is completed. Instruction tape,
This is a device for writing a defect ID, a defect name, and defect end information. In the above description, the defect ID is an ID for identifying an individual defect and is not duplicated for each defect.
Is given. A series of IDs of a failure start and a failure end is given a continuous number, or a branch number for distinguishing the start and the end with the same number is provided to make it easy to recognize a pair of IDs. The defect name means the content of the defect. In the case of printing, it refers to a defect type such as printing stains or doctor streaks, and in the paper industry, for example, irregularities in papermaking or foreign matter. The content of the defect may be visually determined by a processing person or, if the defect can be determined by an inspection device, input data may be obtained from the device. The defect content is input as a numerical value or the like coded for each type.

The defect start information means that the defect starts from the tape position. The failure end information means that the failure ends at the tape position. For the defective position indicating tape with respect to the defective start position, the number of meters from the winding supply end of the tape position is measured by the winding length measuring device 3 located downstream of the web as described later, and the data is read. The writing start position (absolute value) information is written by the writing unit 4. Similarly, for the defect indication tape for the defect end position,
The failure end position (absolute value) information is written. In the above description, the measurement of the winding length is started from the winding supply end. However, since a defective portion is included in the printing start portion of normal printing and the initial portion at the time of winding replacement, a portion that can be a product, a so-called regular paper portion. The measurement may be started from the position where the data is supplied.

The data writing section 1 is configured to supply a defective position indicating tape formed of a non-contact IC tag, for example, an indicating tape formed in a continuous label shape. The label may be in a continuous form through a separable perforation. When writing data to this label, writing from a close position can prevent interference with other labels, and it is preferable to use a type that can write with close contact or close proximity, but in the later process it should be possible to communicate over a relatively long distance In some cases, the communication distance of the label is defined by the antenna shape and the resonance frequency and is not variable. Therefore, in order to satisfy both requirements, a writing distance of about several cm to 10 cm is preferable.

The tape attaching section 2 is an apparatus section for attaching the defective position indicating tapes 31b and 31e on which data has been written to a web. The continuously supplied label preferably has a pressure-sensitive adhesive surface protected by a release paper, and the release paper can be removed by an appropriate labeling device and attached to the edge of the web paper web. . Since the data writing and the tape sticking are performed immediately and at the same position in accordance with the purpose, it is general that the data writing unit 1 and the tape sticking unit 2 are integrated devices.

The take-up length measuring device 3 is a measuring device for measuring the web passing length over the entire length, and is also installed near the paper discharge portion and further downstream from the tape attaching portion 2.
The measuring device measures the total length of winding, the defective start position, and the defective end position. Further, based on the measured values, the numerical values of the defective start position and the defective end position of the defective position indicating tape are written on the defective position indicating tape by the data reading / writing section 4. Since the total length of the winding is also measured by the measuring device, the data is rewritten based on the numerical value. A commercially available yam meter, rotary encoder, or the like can be used as such a measuring instrument.

The data read / write unit 4 is installed close to the winding length measuring device 3. The device reads the defect ID from the storage device (memory) of the non-contact IC tag of the defect position indicating tapes 31b and 31e attached thereto,
The numerical values of the defect start position and the defect end position acquired from the winding length measuring device 3 are written to each defect position indicating tape as position information. For these writings, the numerical values may be sequentially written when the tape reaches the writing portion position. The data read from the defective position indicating tape and the contents of the written data are stored in a storage unit provided in the data reading / writing unit 4 for a necessary period.

Normally, data read / write is performed at 125 kHz.
(Mid-wave), 13.56 MHz, 2.45 GHz (microwave), etc., in a non-contact manner. Generally, the contact type is about 2 mm, the proximity type is about 20 cm, and the proximity type is 1 mm.
It is said that the writing distance is about m, or several m in the case of the microwave type. Also in the data reading / writing section 4, it is preferable to write from a short distance of about several centimeters in order to write in close proximity to the defective indication tape of the web and to prevent interference with other defective indication tapes. However, as will be described later, when rewriting is performed collectively by the writing unit 4 fixed to all the defective indicating tapes wound in the winding, the diameter of the winding may be 1 to 2 m. Communication from a distance is required. In this case, a portable rewriting device may be provided as a dedicated rewriting device.

The arithmetic unit 5 is composed of a simple computer device, and performs the following arithmetic operation based on the position information of each defective indication tape obtained from the winding length measuring device 3 and the numerical value of the total winding length. . (1) A defect instruction tape (a pair of tapes indicating start / end) of a pair of defect IDs is searched, and start position information (absolute position) from the defect position instruction tape indicating the start position, and a defect position instruction tape indicating the end position To end position information (absolute position)
, Calculate the difference between the two, two bad tapes,
Write as a defective position (relative position). That is, this numerical value represents the length of the defective portion, and the relative position from the start information indicating tape to the end information indicating tape, and the relative position from the end information indicating tape to the start information indicating tape. Will be recorded. (2) In the data writing unit 4 or the data rewriting unit 6, an operation of subtracting the start position information or the end position information from the entire winding length in order to rewrite the start position information and the end position information of all the defect information. I do. That is, since the defective instruction tape indicating the end position becomes the start information instruction tape in the next step, the display change and the numerical calculation for writing the subtraction operation value as new position information are performed.

The data rewriting section 6 can be used also as the data reading / writing section 4. However, since different characteristics are required depending on the communication distance with the defective position indicating tape, a separate apparatus must be provided. Is preferred. The data rewriting unit 6 rewrites the defect start position and the defect end position and rewrites the absolute values of the defect start and end position information based on the above-described calculation results. This rewriting is for facilitating the handling of the winding in the next step. By rewriting the defective start information to the defective end information and the defective end information to the defective start information, data erroneous recognition in the next step is reduced.

For example, in the winding whose total winding length is measured to be 1000 m by the winding length measuring device 3, a first defective start position, a1,
2 has a first defective end position, a3 has only a second defective start position, and a4 has only a second defective end position.
In the next step, (1000-a4) is the first failure start position, (1000-a3) is the first failure end position, and (10
00-a2) is the second defect start position, and (1000-a2)
1) is given as new data as a second defective end position. By doing so, the trouble of backcalculating the defect start position one by one in the next process can be omitted.

At the time of data rewriting performed after the whole semi-finished product has been wound, a defective instruction tape is called and data is rewritten for each tape. At this time, there are a plurality of defective position instruction tapes. In the case of simultaneous response from each tape, data collision (data collision) may occur. There are various methods for avoiding such data collision (anti-collision). In the case of the present invention, the data reading / writing unit 4 or the data rewriting unit 6 stores each defect identification ID of the defect position indicating tape. So
The process is relatively easy as compared with the case of searching for an unknown ID.

For example, a collision can be avoided and a defective ID can be searched by a method disclosed in Japanese Patent Application Laid-Open No. 8-36623. That is, for example, when the defect ID is composed of 4 bits as shown in Table 1, a high-level signal whose signal level is “1” or more depending on whether the 0th bit is “1” or “0” is called, At this time, the response of the low-level “0” having no response is prohibited for a while. Such an operation is sequentially performed on the first, second, and third bits, and finally, a target defect ID can be searched. In the case of Table 1, a high-level signal is called from the first to the third time, and a low-level signal is called at the fourth time, and the defective ID “1110” can be searched in bit display.

[Table 1]

When the target defect ID is retrieved, the data writing unit 4 or the data rewriting unit 6 performs the following process for the defect start information, the defect end information, the defect start position information, and the defect end position information of the defect ID. Rewrite data. Subsequently, the next defective ID is searched and rewritten similarly. Since the number of defective indicating tapes applied to a semi-finished product as a single roll is at most several tens, even though rewriting sequentially is actually performed in milliseconds as described above, Can be performed in a very short time.

FIG. 3 is a diagram showing the relationship between defective instruction tapes before and after data rewriting of a semi-finished product. FIG. 3A shows a state of the semi-finished product before rewriting, and FIG. 3B shows a state of the semi-finished product after rewriting. In the printing process of FIG. 3A, the web 20 advances rightward as indicated by the arrow, but in the inspection process, the web 20 advances in the reverse direction. Need to be displayed. In the case of processed products such as printing, if there is no subsequent processing step, the defective portion is removed in the rewind inspection process and the product is produced, but in the conventional inspection process, the defective indication tape attached in the printing process is used as it is Therefore, it was not possible to identify which instruction tape indicates the start or end of the failure, and which tape and which tape indicate a pair of failure ranges. Further, since the content and quantity of each defect cannot be recorded directly on the tape, it is necessary to record them on a form or a storage device such as a computer in order to correctly recognize them. In the present invention, FIG.
In the inspection process as described above, the failure start information tape is attached to the start point of the failure and the failure end information tape is attached to the failure end point so as to match the inspection process, so that the instruction contents of the tape are very clear. At the same time, since the content of the defect (the type of defect and the number of meters) is directly recorded on the tape, all the recording operations as described above can be omitted.

FIG. 4 is a diagram showing a situation in which defect information is managed using a defect instruction tape. FIG. 4A shows a state in which unremoved failures are managed, and FIG. 4B shows a state in which removed failure information is managed. In the manufacturing process of a product, it is often convenient in the process to proceed to the next process while leaving some small defects, and to remove the defect in the final process. Conventionally, in such a case, in the inspection process, which defect was removed or not removed was determined by a person in charge while checking the defect information such as data and forms. With this device, semi-finished product winding (winding with defective indication tape affixed with this device)
As shown in FIG. 4A, unremoved defect information (what defect remains at which position and at what position) can be obtained by reading data in batch from the reading device. Further, the defective portion 2 removed after the completion of the defect removing process
By reading the defect data affixed to No. 5 with a data reading device, it is possible to obtain removed defect information (how many pieces of defective information are removed) (FIG. 4B). Since it is preferable that the processing can be performed even in a state where the removed defective portion is put in the garbage basket, a device that can read in a wide range is required. Therefore, it is not necessary to prepare a data storage device or a form to manage the defect information. The use of such a failure indicating tape, a read / write device, and a rewrite device has an advantage that the storage device is not required when constructing the automatic defect removal device, and thus the entire device can be simplified.

Next, information complementation when a defective tape is missing will be described. FIG. 5 is a diagram illustrating a case where a defective instruction tape is missing in a semi-finished product. FIG. 5 (A) shows the case of normal
FIG. 5B shows a case where the defective indication tape 31b is missing. When using the defective position indicating tape of the present invention, if one of the pair of defective position indicating tapes remains, the absolute position of the defective position indicating tape and the relative position from any of the tapes are recorded, Based on this, the other missing absolute position can be calculated. As described above, the information at the time of tape loss can be supplemented, so that even in the unlikely event that the tape is missing, the defect information can be correctly managed.

Next, the defective position indicating tape of the present invention will be described. FIG. 6 is a diagram illustrating an example of a defective position indicating tape formed of a non-contact IC tag. The IC tag is also called a non-contact data carrier, and can form a coil circuit 302 on a base material 301 such as plastic, and form a resonance circuit with the coil and the capacitor element to receive and transmit a radio wave of a certain frequency. Generally, a frequency band of 125 kHz (medium wave), 13.56 MHz, and 2.45 GHz (microwave) is used. In the case of the illustrated example, the coil pattern 302 forms a jumping circuit on the back surface of the base material 301 by the conductive member 305, and the coil connection terminal
Although connected to the bumps on the back surface of the C chip 304, a circuit is formed on the front and back surfaces of the substrate, or an IC
By connecting the chips, the conductive member 305 may not be used. In the case of FIG. 6, the capacitor is built in the IC chip. The IC chip 304 includes a memory,
The predetermined information such as the above-mentioned defect ID can be stored.

Such an IC tag is formed by forming a coil pattern 302 by photo-etching or etching after printing a resist on a metal foil such as an aluminum foil laminated on a resin base material, mounting an IC chip, and providing a protective coating. Can be formed. In the prototype example, 35mm x 8
As a rectangular antenna shape of 0 mm, a diameter of 0.22 mm
When the wire is wound five turns, a communication distance of 10 cm or more is obtained.

As the resin base material 301 used for the IC tag, various materials such as PET, polypropylene, polyethylene, polystyrene, and nylon can be used, and the thickness can be 10 to 200 μm. The thickness is more preferably from 15 to 100 μm from the viewpoint of cost and the like. As the metal foil, a copper foil, an aluminum foil or an iron foil can be used, but an aluminum foil is preferable from the viewpoint of cost and workability, and its thickness is preferably about 6 to 50 μm. As a form easy to use as the defective position indicating tape, a surface having an adhesive or an adhesive layer attached to the web, a release paper for protecting the layer is provided, and in use, the release paper is peeled off to remove the web. It is preferable to attach it to It is one of the preferred embodiments that each defective indication tape is made continuous through a perforation 306 as shown in FIG. 6, and the perforation is cut and attached at the time of application.

[0031]

As described above, according to the defect information adding apparatus of the present invention, since the non-contact IC tag capable of storing information is used on the defective position indicating tape, the information can be recorded in a non-contact manner. At the same time, since various types of defect information can be recorded in the memory section of the IC tag, it is not necessary to manage the form of data required conventionally and the management of a separate storage device, thereby simplifying the steps and operations. Further, according to the defect information rewriting device of the present invention, data can be rewritten accurately and instantly for the next process, and the number of defective portions removed can be grasped. Without the need for proper management, and the process can be labor-saving. Since the defect position indicating tape of the present invention uses a non-contact IC tag and records individual defect information such as a defect ID, it is possible to easily and accurately grasp the defect state and to save labor. .
