  The present invention provides a magnetic detection function capable of printing a medicine booklet stored in a packaging box with magnetic ink, detecting the magnetism of the printed part, and determining or identifying the presence and type of the booklet. Document and its detection method.

  2. Description of the Related Art Conventionally, for example, a medicine packaging box contains a booklet that is an instruction manual for a medicine in the packaging box. Since this form must be attached for each medicine, it is necessary to check whether the form is put in the packaging box after the medicine is stored in the packaging box or after sealing.

  As a method of confirming the storage of the written documents before sealing, the written documents are put in the packaging box by using the counting control method to confirm by comparing the number of supplied written documents and the number of pre-packaged boxes, or using the photoelectric tube sensor. There is a method for detecting the insertion of a book just before the insertion. In addition, there is also a method in which after a written book is inserted into the packaging box, the packaging box is photographed with a camera in a state before sealing and the presence or absence of the written book is confirmed by image processing.

  In addition, as a method of storing a letter in a packaging box and detecting the letter after sealing, the weight of the packaging box after the letter book is stored is checked to detect the presence of the letter, or a fluorescent agent is printed on the letter. In addition, there is a method of determining the presence or absence of a booklet by applying light of a specific wavelength to the packaging box after insertion of the booklet and checking the fluorescence contained in the reflected light by photoluminescence. In addition, X-rays are applied to the packaging box after storing the letter, and the shadow of the letter in the packaging box is detected, or microwaves are emitted from outside the packaging box to detect reflected waves from the letter. There is also a method for determining the presence or absence of a book.

  Furthermore, there is also a Noh book method that prints a bar code on a noh book and reads the bar code just before putting the noh book into the box to check whether there is a difference in type in addition to the noh letter detection.

  In addition, the mark with magnetic ink is printed on the Noh book, and the Noh book with the mark is stored in the packaging box, and the magnetic particles inside the Noh ink are applied by applying a magnetic field to the Noh letter from the outside of the packaging box. There has also been proposed an apparatus for confirming a book by detecting a weak magnetic field of a magnetized mark in a packaging box and magnetized.

  Furthermore, as a method of confirming not only the presence of a booklet but also information such as type, there is no difference in the type of booklet by printing a barcode on the booklet and reading the barcode immediately before putting the booklet in the box. There was also a way to check if.

On the other hand, as a technique for enhancing the safety of a magnetic card or the like and preventing forgery or the like, there is a technique in which a magnetic pattern is formed on a plurality of magnetic tracks as disclosed in Patent Document 1.
Japanese Patent Laid-Open No. 11-25406

  In the case of the above-mentioned conventional method for checking a book before storing it in the packaging box, it is not a judgment whether the book is actually stored, but the book is securely stored in the packaging box. It cannot be determined that In addition, there is a risk that an error may occur when counting is missed or stored in the box after detection.

  In addition, when detecting the weight, the type of booklet cannot be identified. In addition, in the case of photoluminescence, or in the case of applying X-rays or microwaves, there are adverse effects on materials and stored items of books, effects of temperature and humidity, and so on, which are not practical. In addition, the method of reading a barcode is also undetectable if the booklet is not stored in the packaging box for some reason after reading the barcode.

  Therefore, with the above-mentioned conventional method of detecting a book, it is not possible to expect perfection of book management, especially in the case of pharmaceuticals, if there is no receipt or an incorrect receipt. , There is a possibility that all the products in the lot must be opened and inspected, or the products on the market must be collected.

  On the other hand, in the case of a method for detecting a booklet in a packaging box with magnetic ink, the booklet must be detected from outside the box, and the ferromagnetic ink layer printed on the booklet is detected by a magnetic sensor such as a magnetic head. The magnetic field was not detected by contact, but the distance between the ferromagnetic ink layer and the magnetic sensor was wide, and detection was difficult. Therefore, the magnetic detection is still used only for detecting the presence or absence of a medicine booklet, and no type detection has been put into practical use.

  In addition, it is conceivable to use an IC card or the like as a means for reading the stored items, but this system is expensive and cannot be applied to a large amount of products.

  The present invention has been made in view of the above-mentioned problems of the prior art. A printing layer can be formed of ferromagnetic powder with a simple configuration by an existing printing method. It is an object of the present invention to provide a magnetic detection document that can be reliably detected and its detection method.

  In the present invention, a print pattern using magnetic ink containing a ferromagnetic powder such as ferrite is printed in parallel on a plurality of rows on a paper, and at least one of the print patterns is a reference pattern on which reference data is recorded. The other at least one print pattern is a magnetic detection book that is an identification pattern for identifying the book.

  The ferromagnetic powder is a ferromagnetic powder having a holding power of 2750 oersted or more. Further, the print pattern is formed by arranging a plurality of independent print units in series for each column. Furthermore, the printing pattern may be printed in a superimposed manner in the thickness direction of the paper.

  Further, before the magnetic ink of the printed pattern is solidified, the ferromagnetic powder in the printed pattern of the written book for magnetic detection is magnetized.

  The magnetic ink having the printed pattern includes an anisotropic ferromagnetic powder having an average particle diameter of 1.0 to 2.0 μm, for example, about 1.3 to 1.6 μm, and has a holding power of 2750 oersted or more. The magnetic detection book is formed by magnetizing the ferromagnetic powder in the printing pattern after the printing pattern is formed by offset printing and before the magnetic ink is solidified after printing.

  Further, according to the present invention, a print pattern using magnetic ink containing a ferromagnetic powder is printed in parallel on a plurality of rows on a paper, and at least one of the print patterns is a reference pattern in which reference data is recorded. Using at least one printed pattern of the magnetic detection document provided as an identification pattern for identifying the document, before or after storing the magnetic detection document in a packaging box, Magnetic detection that magnetizes each printed pattern, detects the magnetic field of the reference pattern and the identification pattern from the outside of the packaging box during movement of the packaging box, and discriminates the signal of the identification pattern based on the signal of the reference pattern It is a method for detecting utility books.

  The magnetic detection book and its detection method of the present invention are capable of detecting a printed pattern with magnetic ink with high sensitivity, and the presence / absence and type of the book in the packaging box can be reliably confirmed from outside the box after packaging. Can be confirmed. Moreover, printing with magnetic ink is easy. In particular, when printing, offset printing using an existing printing apparatus can be used, and no new equipment or the like is required, thereby reducing costs. In addition, it has high detection sensitivity and can be printed once, and can detect highly reliable books.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show an embodiment of the present invention. For example, a booklet 12 stored in a packaging box 10 containing a product 11 such as a medicine is detected. As shown in FIG. 1, a plurality of rows of printed patterns 14 of magnetic ink containing ferromagnetic powder are formed in the performance book 12, along with explanatory notes 13 such as an effect note and a cautionary note.

  The printing pattern 14 is formed by arranging a plurality of independent rectangular printing units, for example, printing units having a length of 5 mm to 10 mm and a width of about 0.5 mm to 5 mm in series. The print pattern 14 includes a reference pattern 14a in which print units are arranged in series according to a predetermined rule as a reference for discrimination, and an identification pattern 14b in which the print unit is set for each type of booklet 12. The reference pattern 14a and the identification pattern 14b are linearly arranged and positioned in parallel with each other. The ferromagnetic powder contained in the printed pattern 14 is a powder of Fe, Ni, Co, a compound thereof, or an alloy, and is a ferromagnetic powder having a holding power of 2750 oersted or more. For example, an anisotropic ferrite powder having an average particle size of 1.0 to 2.0 μm, for example, about 1.3 to 1.6 μm.

  The printed pattern 14 of magnetic booklet of the certificate 12 is printed by changing the number and arrangement of the identification patterns 14b of the printed pattern 14 in accordance with the type of medicine stored in the packaging box 10, for example. The printing method can be selected as appropriate, such as flexographic printing or offset printing, but flexographic printing capable of printing magnetic ink thickly is preferable for magnetic field detection. However, general offset printing is preferable from the viewpoint of printing the book of books 12, and the printing pattern 14 by offset printing can be detected by using magnetic ink containing the ferromagnetic powder having high holding power.

  As shown in FIG. 4, in the printing book detection method of this embodiment, in a printing factory 15 of a printing company, a printing pattern 14 corresponding to a medicine as a predetermined storage is printed in a magnetic ink in a printing process 21 of a printing book 12. To print. After the printing pattern 14 is printed, the magnetizing device 22 magnetizes the printing pattern 14. Here, when the printing pattern 14 is printed and magnetized, it is preferable to magnetize the ferromagnetic powder in the printing pattern 14 of the book 12 before the magnetic ink is solidified. This is because by magnetizing the ferromagnetic powder before the magnetic ink is solidified, the easy magnetization axis of the ferromagnetic powder is magnetized so as to be aligned with the magnetic field direction, and the residual magnetic flux density can be improved. . Next, the Noh book folding device 23 folds the Noh book 12 to a size that can be stored in a predetermined packaging box 10. Then, the folded booklet 12 is conveyed to the pharmaceutical company 25 of the product 11.

  The pharmaceutical company 25 is provided with an automatic machine for inserting the booklet 12 into the packaging box 10 and stores the prescribed booklet 12 in the packaging box 10 for each prescribed medicine. Further, a magnetic field detection device 24 and a spring device 26 on the downstream side are provided along the belt conveyor 20 for conveying goods. The jumping device 26 jumps out the packaging box 10 when the booklet 12 is not stored in the packaging box 10 or when a different booklet 12 is stored in the packaging box 10.

  In this embodiment, the booklet detection by the magnetic field detection device 24 detects the magnetic field of the printed pattern 14 of the booklet 12 from the outside of the packaging box 10 by the magnetic field detection device 24 while moving on the belt conveyor 20. As shown in FIG. 2, the detection waveform by the magnetic field detection device 24 is detected by a waveform (A) corresponding to the reference pattern 14a and a waveform (B) corresponding to the identification pattern 14b depending on the number and arrangement of the identification patterns 14b. Is done. Then, using the waveform of the reference pattern 14a as a reference, the stored booklet 12 is discriminated from the waveform of the identification pattern 14b to identify the type and the like.

  Alternatively, the printed pattern 14 may be magnetized by the pharmaceutical company 25 of the product. In this case, after storing the book 12 in the packaging box 10, it is magnetized from the outside of the box. Thereafter, in the same manner as described above, the magnetic book detection device 24 detects the book 12 and identifies the type and the like.

  According to the magnetic detection document and detection method of this embodiment, the identification pattern 14b of each document 12 is changed in correspondence with a plurality of types of stored items and printed, and each product 11 from outside the packaging box 10 is printed. Therefore, it is possible to accurately detect and identify the presence and type of the book 12. Moreover, even if a timing shift occurs in the detection signal when the identification pattern 14b is recognized due to fluctuations in the belt conveyor 20, the reference pattern 14a and the identification pattern 14b arranged in parallel have the same timing shift. It is difficult to generate a recognition error by discriminating the identification pattern 14b based on the reference pattern 14a. Furthermore, by using a ferromagnetic powder having a holding power of 2750 oersted or more, a magnetic field can be accurately detected even if the magnetic sensor of the magnetic field detector 24 is not in contact with the printed pattern 14. The noh book 12 in the packaging box 10 can be accurately detected through the side wall space of the box. Further, since it has a high holding force, it is hardly affected by an external magnetic field during conveyance. In addition, it is possible to accurately detect the amount of magnetic ink by offset printing, and the offset printing that has been generally used can be used as it is, and the number of times of printing may be about once, and the printing speed and other conditions It is possible to print without dropping. Therefore, the cost increase can be minimized.

  Further, by magnetizing the print pattern 14 before the magnetic ink is solidified, accurate detection is possible even if there is a gap with the magnetic sensor. Further, by magnetizing in the printing process, it can be magnetized by the magnetic head at a closer position, and can be stably magnetized with a strong magnetic field.

  5A, the reference pattern 14a and the identification pattern 14b may be printed so as to overlap each other in the thickness direction on the front and back of the paper surface of the book. As shown in b), the reference pattern 14a and the identification pattern 14b may be printed one on the other side of the paper of the book of writing 12 in the thickness direction.

  The magnetic detection book of the present invention and the detection method thereof are not limited to the above embodiment, and the ferromagnetic powder in the magnetic ink may be an appropriate ferromagnetic metal powder. The particle shape and size can be set as appropriate. Furthermore, the print pattern of magnetic ink should just be detectable, and a magnitude | size, a shape, and a number can be selected suitably. Further, the print pattern may be continuous, or the stored pattern may be identified by changing the magnetic field pattern during magnetization. Further, the contents to be detected are appropriately used for the contents stored in the packaging material, in addition to the medical certificate, food instructions, confectionery gifts, and the like.
