Description

  The present invention relates to a form body in which a predetermined number of magnetic marks are formed.

  In recent years, for example, after enclosing a form body in a sealed body, it has been delivered to individual destinations. Whether the sealed body actually contains a form body for each individual destination, or whether different form bodies are mixed. Have been inspected. It is necessary to surely recognize the form body when inspecting the form body including such a case.

  Conventionally, in order to perform matching of a form encapsulated in a sealing body, it is possible to determine whether the matching is correct or not by attaching a mark or code for matching to the form and recognizing the mark or code. Generally done. Regarding the mark and code for matching attached to such a form, there are some proposed in Patent Document 1 below.

  In Patent Document 1, a reference symbol (bar code) is attached to a sheet, the reference symbol is printed with metal or metal powder ink, and the matching symbol is read by an inspection apparatus using X-ray transmission to perform a matching inspection. It has been proposed. In addition to ink, a technique for fixing toner containing conductive powder has also been proposed.

  However, as proposed in the above-mentioned Patent Document 1, when forming a reference symbol (bar code) on a sheet, variable data can be easily obtained by printing with metal or metal powder-containing ink that can be detected by X-rays. However, if the amount of metal or metal powder contained in the ink has a characteristic upper limit of ink and there are some inclusions on the forming sheet, In some cases, the verification symbol is not recognized or erroneously recognized, and the system using X-rays is expensive.

  On the other hand, a technique for detecting contents with a magnetic material instead of X-rays is proposed in Patent Document 2 below. According to Patent Document 2, ink or paint containing a ferromagnetic powder that causes a sharp magnetization reversal when an alternating magnetic field exceeding the coercive force possessed by itself is applied to the contents stored in the packaging box. It is applied and a detection mark is provided.

  What is proposed in Patent Document 2 is that a generating coil and a detecting coil for applying an alternating magnetic field exceeding the holding force of the ferromagnetic material are arranged on both sides of a detecting mark provided on the contents. Thus, since the detection mark is detected, it is not practical to apply this to the matching of the form body because it may be expensive.

  In view of the above Patent Documents 1 and 2, the present applicant has conceived that a matching mark is formed of a magnetic material and is detected by a magnetic sensor in a non-contact manner.

  FIG. 6 is an explanatory diagram showing an example of a form that is a premise of the present invention, and FIGS. 7 and 8 are explanatory views of mark detection of the form in FIG. 8A to 8C, the magnetic mark (111A) has a rectangular shape of 8 mm × 3 mm, and the residual magnetic flux is 4000 (G: Gauss) in the magnetic ink having a holding force of 1500 (Oe: unit Oersted). When magnetized at a density, the detection state of the MI sensor (magnetic sensor) manufactured by Aichi Micro Intelligent Co., Ltd. is output at a position 3 mm in height from the sealing body 105 (2.5 V is grounded (GND)). It is shown.

  FIG. 6A shows a form to be enclosed in a sealing body. In FIG. 6A, the continuous form 101 has marginal parts 102A and 102B formed on both sides in the conveying direction, and an individual form 103A is formed. One form body 103 composed of ˜103C is continuous, and is printed on one of the individual form bodies 103 </ b> A to 103 </ b> C with ink mixed with magnetic powder in the mark forming region at one end thereof. Thus, for example, six magnetic marks 111 </ b> A to 111 </ b> F are connected in a direction perpendicular to the transport direction (width direction), and any of the magnetic marks 111 </ b> A to 111 </ b> F is magnetized for each form body 103. In addition, an address, a name, an identification code, and the like are printed at predetermined locations on any of the individual slip forms 103A to 103C.

  In the continuous form body 101, the marginal parts 102A and 102B are removed in one process during conveyance, and the continuous form body 101 is cut into a single form body 103 and bent at a folding line 104 by, for example, Z-folding. As shown in FIG. 6B, such a folded form 103 is enclosed in a sealing body 105, and at this time, the address printed on the window 106 of the sealing body 105, A form 103 is enclosed so that a name, an identification code, and the like are displayed. In this state, the position of a magnetic mark (hereinafter referred to as a magnetic mark) magnetized on any of the magnetic marks 111 </ b> A to 111 </ b> F formed on the form body 103 and the window 106 of the sealing body 105 are exposed. The recognition code is recognized and matching is performed.

  As shown in FIG. 7A, the matching is performed by capturing and recognizing the identification code that is conveyed to the imaging position (not shown) by the conveying means 121 after the sealing step and is exposed from the window 106, and further, the mark detection position. The magnetic mark 111A to 111F is detected by any of the magnetized magnetic marks 111A and 111F detected by the mark detection unit 123 that is transported and arranged, and matching is performed at the recognized identification code and the position of the detected magnetic mark. Is.

  In other words, the mark detection unit 123 corresponds to the magnetic marks 111A to 111F of the form 103 enclosed in the conveyed sealing body 105 by the magnetic sensors 131 to 136, respectively. The positions of the magnetic marks are discriminated by detection by 131 to 136. By the way, as shown in FIG. 7B, the magnetized magnetic mark (here, magnetic mark 111A) has the maximum magnetic force (absolute value) in the N extreme portion and the S extreme portion, The magnetic force gradually decreases according to the distance from the end, and the magnetic force is minimized (zero) at the switching point between the N pole and the S pole.

Japanese Patent No. 3098557 JP 2003-285808 A

  However, as shown in FIG. 7A, when the form body 103 is conveyed on the conveying means 121 and a so-called flutter occurs in the vertical direction, as shown in FIGS. When the magnetic mark and the magnetic sensor approach each other due to the fluttering, the output value of the magnetic sensor spreads in the direction away from both ends of the magnetic mark, which affects which of the adjacent magnetic marks or magnetic marks is detected. There is a problem that it becomes impossible to discriminate.

  Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a form that allows a formed magnetic mark to be reliably detected.

  In order to solve the above-mentioned problem, in the invention of claim 1, a predetermined number of magnetic marks are arranged in a direction perpendicular to a transport direction when transported later by forming a magnetization line in a magnetic material, A form for identifying the magnetic mark arrangement position by detecting the magnetic mark in a non-contact manner by a magnetic sensor arranged at a predetermined interval, wherein the magnetic mark includes at least three magnetization lines from the outside. Focusing on the inside, the magnetization direction of the magnetization line is the same polarity on the inside.

  According to a second aspect of the present invention, a plurality of magnetic bodies are formed at predetermined intervals in the vertical direction, and any one of the magnetic marks is an object, and the magnetic mark is a non-magnetized region at an outer end portion of the magnetic line. Is formed.

  According to the first aspect of the present invention, a predetermined number of magnetic marks are arranged in a direction perpendicular to the conveyance direction of the form body, and the magnetic marks are focused from the outside to the inside by focusing at least three magnetization lines. By adopting a configuration in which the magnetization direction is the same polarity between the inner sides, the magnetic mark is formed by superimposing and increasing the magnetic force at the poles focused on the inner side of at least three magnetization lines. The distance to the sensor can be set to a large value, so that it is not possible to determine whether the magnetic mark is an adjacent magnetic mark or not even if the magnetic mark and the magnetic sensor approach each other due to vertical flapping during transport. Moreover, since the difference between the magnetic force on the inside and the magnetic force on the outside becomes large, the formed magnetic mark can be reliably detected.

    According to a second aspect of the present invention, a plurality of magnetic bodies are formed at predetermined intervals in the vertical direction, and any one of them is a target of a magnetic mark, and the magnetic mark is placed in a non-magnetized region at an outer end portion of the magnetic line. Since the magnetic force of the pole adjacent to the non-magnetized area is reduced by forming the, the influence from the adjacent magnetic mark is reduced even if the form body flutters in the direction perpendicular to the transport direction during transport. Therefore, the formed magnetic mark can be detected more reliably.

It is the block diagram which showed a part of the form body of this invention. It is explanatory drawing which showed a part of mark detection system at the time of performing the matching of the form body of this invention. It is explanatory drawing of the magnetic sensor detection of the mark detection system in FIG. It is explanatory drawing of the other shape of the magnetic body mark formed in the form body of this invention. It is explanatory drawing of the other magnetized state of the magnetic body mark formed in the form body of this invention. It is explanatory drawing of an example of the form body used as the premise of this invention. It is explanatory drawing (1) of the mark detection of the form body in FIG. It is explanatory drawing (2) of the mark detection of the form body in FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing a part of a form of the present invention. In FIG. 1 (A), for example, a single form body (103B) of a single form 11 (103) as shown in FIG. 6 (A) is shown as a Z-folded individual form (103B). As an example, a case will be described where the magnetic marks (13A to 13E) are formed at predetermined intervals in the direction perpendicular to the transport direction when the magnetic marks (13A to 13E) are transported later. That is, this is a case where each individual magnetic body is used as a magnetic mark. In the case where a magnetic line is formed by a predetermined arrangement on a single magnetic body to form a magnetic mark, it will be described with reference to FIG.

  As shown in FIG. 1B, the magnetic marks 13 </ b> A to 13 </ b> E converge at least four magnetization lines (N-pole to S-pole) from the outside to the inside at equal intervals. Formed in shape. Specifically, in the drawing, two rectangular partial magnetic bodies 13-1 and 13-2 are brought into contact with each other in the horizontal direction, and the partial magnetic bodies 13-3 and 13-4 are formed above and below the central portion. In this configuration, the short sides of each of the rectangular shapes are in contact with each other, and the magnetic lines are focused from the outside to the inside by the partial magnetic bodies 13-1 to 13-4 capable of forming four magnetization lines. It will be. Such magnetic body marks 13A to 13E can be formed by a general printing technique, for example, by mixing magnetic powder into printing ink.

  One of the magnetic marks 13A to 13E is magnetized by being magnetized, and as shown in FIG. 1B, each of the partial magnetic bodies 13 of the magnetic marks 13A to 13E. The magnetic lines formed on -1 to 13-4, for example, are magnetized by magnetizing the focused inner sides with the same S pole and the outer sides with the same N pole (or vice versa). It is.

  The magnetic force of such a magnetic mark is a value obtained by superimposing each other's magnetic force on the inner poles (S, S, S, S) where the partial magnetic bodies 13-1 to 13-4 are focused. The magnetic force of the same-polarity (N, N) portion outside the magnetic bodies 13-1 and 13-2 is a value for each pole. For example, if the lengths of all the magnetization lines are equally divided, the magnetic force ratio (absolute value) in the horizontal direction is 0.5 (N pole of the partial magnetic body 13-1): 2 (inner center) Part): 0.5 (N pole of the partial magnetic body 13-2). In addition, the magnetic force value at the time of magnetizing is determined corresponding to the position of the magnetic sensor to be detected and the vertical flapping at the time of conveyance (described in FIG. 3). The magnetic sensor detects the magnetic mark when the form body 11 is conveyed in a mark detection system described later.

  Magnetization of the magnetic mark is performed for each part constituting the magnetic mark for each magnetic line, for example, by changing the poles at both ends of the gap regardless of contact or non-contact by a magnetic recording head in which a minute gap is formed. The magnetic bodies 13-1 to 13-4 can be magnetized by passing through the start time and the end position, and the magnetization direction is determined by the polarity to be changed at this time.

  Here, FIG. 2 is an explanatory diagram showing a part of the mark detection system when matching the forms of the present invention. FIG. 2 shows a part of the mark detection system 21, for example, a mark detection unit 23 is arranged at a predetermined position in the conveyance direction in the conveyance unit 22 for belt conveyance, and the mark detection unit 23 includes the form body 11. The magnetic sensors 24A to 24E corresponding to the magnetic marks 13A to 13E are provided.

  As the magnetic sensors 24A to 24E, for example, MR (magnetoresistive effect) sensors, magnetism using the MI effect (high frequency skin effect) in which the magnetic impedance changes greatly by an external magnetic field when a high frequency current is applied to the magnetosensitive medium. An impedance sensor (MI sensor) can be employed.

  On the other hand, the sealing body 31 is sequentially transported on the transporting means 22, and the sealing body 31 is provided with a window 32 and a form body 11 having an individual form body shown in FIG. It is enclosed. As the corresponding positions of the magnetic sensors 24A to 24E with respect to the magnetic marks 13A to 13E, for example, the inner center position of each of the magnetic marks 13A to 13E is a position that overlaps the magnetic sensors 24A to 24E in the transport direction.

  FIG. 3 is an explanatory view of magnetic sensor detection of the mark detection system in FIG. In FIG. 3A, each of the partial magnetic bodies 13-1 to 13-4 of the magnetic mark 13 is formed into a rectangular shape of 8 mm × 4 mm, and each of them is 4 mm: 4 mm on a magnetic ink having a holding force of 1500 (Oe). Assuming that the residual magnetic flux density is 4000 (G) (preferably 1500 (G) or more) in different magnetization directions, and magnetized in the magnetization direction shown in the figure (FIG. 1 (B)), the height of the sealing body 31 is 3 mm. The detection state of the MI sensor (magnetic sensor) manufactured by Aichi Micro Intelligent Co., Ltd. is indicated by the output value (V).

  FIGS. 3B and 3C show sensor output values when the magnetic sensor is detected with a shift of 1 mm from the center with respect to the magnetic mark 13, and as shown in the figure, the center of the magnetic mark 13 is detected. It shows that an output value far exceeding both ends was obtained in the vicinity. This means that the detection distance (height of the magnetic mark and the magnetic sensor is not to be detected at positions away from the magnetization line on both ends of the magnetic mark (outside of the partial magnetic bodies 13-1 and 13-2). ) Can be set to a large value, and the magnetic mark to be detected can be reliably detected by distinguishing adjacent magnetic marks or non-magnetized magnetic marks.

  As described above, the magnetic mark 13 is increased by superimposing the magnetic forces in the inner portions of the four magnetization directions, so that the distance between the magnetic mark and the magnetic sensor can be set large. Even if the magnetic mark and the magnetic sensor approach each other due to the fluttering in the direction, it can be avoided that the magnetic mark cannot be distinguished from the adjacent magnetic mark or the non-magnetized magnetic mark. The mark can be reliably detected. In other words, the size of the magnetic mark can be reduced, and the magnetic mark is different from the difference in magnetic force between the inside and the outside of the partial magnetic bodies 13-1 and 13-2. It is possible to arrange them closer to each other, and it is possible to increase the amount of information for identification with respect to the form body by arranging a larger number with respect to the size of the placed form body.

  In the configuration of the present invention, the detection width of the magnetic sensor with respect to the magnetic mark is narrowed. For example, when the form body is displaced in the direction perpendicular to the transport direction in the sealed body during transport, This can be dealt with by arranging a plurality of magnetic sensors as a set for the mark (magnetic mark).

  Next, FIG. 4 shows an explanatory diagram of another shape of the magnetic mark formed on the form of the present invention. Each of the forms shown in FIG. 4 focuses the magnetic marks 13A to 13E from the outside to the inside other than the form of the four magnetization lines (N pole to S pole magnetization lines) in FIG. 1 as at least three magnetization lines. Is shown.

  FIGS. 4A and 4B are shapes for forming the magnetic mark 13 with the three partial magnetic bodies 13-2 to 13-4 that form three magnetization lines. Is a shape excluding the partial magnetic body 13-1, and FIG. 4 (B) is an inner side between the partial magnetic body 13-3 and the partial magnetic body 13-4, and there is one end of the partial magnetic body 13-2. This is a shape that holds In either case, the focused ends of the inner magnetization lines are the same S pole (or N poles), and the outer ends are the same N poles (or S poles).

  Even if such a shape is used, that is, even if the shape is not symmetrical or vertically symmetrical, the magnetic force superimposed is smaller by one than that in FIG. The difference in magnetic force from the N pole can be made sufficiently large.

  4 (C) and 4 (D) are obtained by changing the shapes of the magnetic marks 13A to 13E shown in FIG. 1, and the magnetization directions are the same as those in FIG. FIG. 4C shows an inner portion where the magnetization lines are converged, and the short sides of the same rectangular partial magnetic bodies 13-1 to 13-4 are shifted by half to form an intangible region K1 in the central portion. It has been made. FIG. 4D shows an inner portion where the magnetization lines are converged, and an intangible region K2 is formed in the central portion by shifting the short sides of the same rectangular partial magnetic bodies 13-1 to 13-4. It is a thing. Even if such intangible regions K1 and K2 are formed, the magnetic force in this portion is increased by superimposing the magnetic force in the portions of the intangible regions K1 and K2, and the partial magnetic bodies 13-1, The magnetic force difference with the outside of 13-2 is made large.

  4E shows that the magnetization direction is the same as in FIG. 1, and an intangible region K2 as shown in FIG. 4D is formed in the inner part, and a large number of magnetizations are formed from the outer side (circumferential side) to the inner side. A line is formed, and a donut shape is formed as a whole. The magnetic force by such a shape can be set to the maximum magnetic force superposition in the inner part.

  FIG. 4F shows that the single magnetic body 13-0 is divided into, for example, five regions as shown in FIG. 1A, and four magnetic lines similar to the above are formed in the region to be a magnetic mark. This is a case where each of the regions is formed as one magnetic mark 13A (13C, 13D). That is, when the magnetic mark is formed, each magnetic body (magnetic body mark) is not a target of the magnetic mark as described above, and one or more magnetic marks are formed on the single magnetic body 13-0. Is formed. The same applies to the three magnetization lines as shown in FIGS. By forming the magnetic mark in this way, the magnetic force can be superimposed on the inner portion of each magnetic mark.

  Next, FIG. 5 shows a configuration diagram of another embodiment showing a part of the form of the present invention. 5A will be described with reference to FIG. 1 as an example, but the same applies to FIGS. 4A to 4E. In FIG. 5A, a non-magnetized region 14 is formed at each outer end of the magnetic line formed in each of the partial magnetic bodies 13-1 to 13-4 of the magnetized magnetic mark. Is. For example, the partial magnetic bodies 13-1 to 13-4 having a length of 10 mm are non-magnetized regions 14 at a ratio of one end region (for example, 1 (non-magnetized region): 4 (magnetization line)) arranged outside. Is formed. As described above, the magnetization can be realized by determining its start time and end position.

  The non-magnetized region 14 has an action of suppressing the diffusion of the magnetic force (magnetic field) of the outer pole (N pole in FIG. 5A) as shown in FIGS. 5B and 5C. Thus, it is possible to reduce the influence of the magnetic force on the adjacent magnetic mark (magnetic mark) and reliably distinguish them.

  That is, even when the magnetic mark and the magnetic sensor come close to each other due to vertical flapping during conveyance, it is possible to distinguish between adjacent magnetic marks or non-magnetized magnetic marks. The magnetic mark can be detected more reliably. In this case as well, as described above, the size of the magnetic marks can be reduced, and the magnetic marks can be placed closer to each other. It is also possible to increase the amount of identification information for the form.

  In addition, although the case where the said non-magnetized area | region 14 was formed in both the long sides of a magnetic mark was shown, the partial magnetic body 13-1, 13-2 of the side adjacent to another magnetic mark (magnetic body mark) is shown. It is sufficient to form only. In the example of FIG. 1A, when the magnetic marks 13A and 13E are magnetic marks, the outer end portions of the partial magnetic bodies only on the magnetic marks (magnetic marks) 13B and 13E side are not magnetized. A region is formed.

  The form body provided with the magnetic body mark of the present invention is suitable when a magnetic body mark detected by a magnetic sensor is formed for matching of the form body.
