Description

  The present invention relates to a form in which a predetermined magnetic mark is magnetized among a predetermined number of magnetic marks to be formed.

  In recent years, for example, after enclosing a form body in a sealed body, it is 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.

Japanese Patent No. 3098557 JP 2003-285808 A

  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. 4 is an explanatory diagram of an example of a form that is a premise of the present invention, and FIG. 5 is an explanatory view of mark detection of the form in FIG. FIG. 4 shows a form to be sealed in a sealing body. In FIG. 4A, the continuous form body 101 forms marginal parts 102A and 102B on both sides in the transport direction, and the individual form bodies 103A to 103C are used. The one form 103 which comprises is continuous, Comprising: It prints with the ink in which magnetic substance powder was mixed in the mark formation area | region of the one end in any one piece form 103A-103C, for example, 6 Two 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 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. 4B, such a folded form 103 is enclosed in a sealing body 105. At this time, the address printed on the window portion 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. 5A, the matching is performed by capturing and recognizing an identification code that is conveyed to an imaging position (not shown) by the conveying means 121 after the sealing step and is exposed from the window 106, and further, a 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.

  That is, 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. 5 (B), the magnetized magnetic mark (here, magnetic mark 111A) has a 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 becomes minimum (zero) at the switching point between the N pole and the S pole. Therefore, the magnetic mark 111A has a detectable detectable range X, X ′ and a non-detectable range Y that is difficult to detect in the vicinity of the switching point with respect to a magnetic sensor (here, the corresponding magnetic sensor 131). Will be included.

  However, as shown in FIG. 5A, when the form body 103 is transported on the transport means 121, a so-called abare occurs in the direction perpendicular to the transport direction (width direction), and the magnetic sensor is fixedly arranged. When 131 (132 to 136) is located in the non-detection range Y, the output value of the magnetic sensor becomes indistinguishable from noise, and the corresponding magnetic mark may not be detected. There's a problem.

  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 body that can reliably detect a magnetized magnetic mark even when a position change in a direction perpendicular to the transport direction occurs during transport. And

  In order to solve the above problems, in the invention of claim 1, a plurality of magnetic marks are formed in a continuous state in a direction perpendicular to a transport direction when transported later, and a predetermined magnetic mark is placed in the vertical direction. The form body is magnetized so as to form a pole, and a predetermined magnetic body mark magnetized is detected by a corresponding magnetic sensor, wherein the plurality of magnetic body marks are at least two magnetic body marks. Is formed of a plurality of magnetic mark sets as one set in the conveying direction, and each magnetic mark constituting each magnetic mark set is at least in the vicinity of the pole switching point when magnetized. A configuration is adopted in which the magnetic sensor is displaced in the vertical direction at a distance in a non-detection range where the magnetic sensor cannot be detected due to a decrease in magnetic force.

  According to the present invention, a plurality of magnetic mark sets that are combined into at least two magnetic marks in the transport direction in the form body are arranged in a direction perpendicular to the transport direction when transported later. Each magnetic mark that is formed in a state and constitutes each magnetic mark set is perpendicular at a distance of a non-detection range at which the magnetic sensor cannot be detected due to a decrease in magnetic force at least near the pole switching point when magnetized. By adopting a configuration in which the set is shifted in the direction, any magnetic mark of the set in which the corresponding magnetic sensor is magnetized even if the so-called abare occurs in the conveyed form body and the position changes in the vertical direction. Thus, it is possible to detect the magnetic mark magnetized with respect to the vertical position change of the conveyed form.

Hereinafter, the best embodiment 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. 4 (A) is shown as a Z-folded individual form (103B). As an example, a pair of magnetic marks (21A, 21B to 26A, 26B) each having a rectangular shape are provided side by side in the transport direction in the magnetic mark formation region at the end, and a plurality of magnetic marks are formed as a pair. The sets 21 to 26 are configured, and the plurality of magnetic mark sets 21 to 26 are formed in a continuous state in a direction perpendicular to the transport direction when transported later.

  By magnetizing any one of the plurality of magnetic body mark groups 21 to 26 so as to form a pole in the vertical direction in units of the unit, the magnetized predetermined magnetic body mark group is made to correspond to a single unit. It is detected by a magnetic sensor. In this case, as described above, the N extreme portion and the S extreme portion of a predetermined magnetized magnetic mark set (herein referred to as magnetic marks 21A and 21B as magnetized magnetic marks 21A and 21B) The magnetic force becomes maximum at, and gradually decreases according to the distance from each end, and the magnetic force becomes minimum (zero) at the switching point between the N pole and the S pole. Therefore, the magnetic marks 21A and 21B have detectable detectable ranges X and X 'and a non-detecting range Y that is difficult to detect in the vicinity of the pole switching point with respect to the magnetic sensor.

  That is, the magnetic sensor marks 21A, 21B to 26A, 26B constituting each magnetic mark set 21 are not detected at least in the vicinity of the pole switching when magnetized so that the magnetic sensor cannot be detected due to a decrease in magnetic force. It is a pair that is shifted in the vertical direction by the distance of the range.

  More specifically, as shown in FIG. 1B, taking as an example a magnetic mark set 21 magnetized with a pair of magnetic marks 21A and 21B, the magnetic force of the magnetic mark 21A is in the N extreme portion and the S extreme portion. The magnetic force becomes maximum, the magnetic force gradually decreases according to the distance from each end, and the magnetic force becomes minimum (zero) at the switching point between the N pole and the S pole. For a magnetic sensor, which will be described later, of the magnetic mark 21A, the output value of the magnetic sensor is within the noise range in the vicinity of the detectable ranges X1 and X′1 in which the magnetic force (absolute value) is in the predetermined value range. The non-detection range Y1 becomes.

  Similarly, in the magnetic mark 21B, the magnetic force becomes maximum at the N extreme portion and the S extreme portion, and the magnetic force gradually decreases according to the distance from each end portion, and at the switching point between the N pole and the S pole. Since the magnetic force is minimum (zero), for the magnetic sensor described later, detectable ranges X2 (= X1), X′2 (= X′1) where the magnetic force (absolute value) is a predetermined value or more, A non-detection range Y2 (= Y1) that is equal to or less than a predetermined value in the vicinity of the pole switching point is provided. The same applies to the other magnetic body mark sets 22 to 26 when magnetized.

  Therefore, the magnetic sensor marks 21A and 21B (22A, 22B to 26A and 26B are also the same), at least in the vicinity of the pole switching when magnetized, the non-detection range Y1 (the magnetic sensor cannot be detected due to a decrease in magnetic force) Y2) is displaced in the vertical direction at a distance of Y2). Here, as an example, the magnetic marks 21A and 21B (the same applies to each of the magnetic mark sets 22 to 26) are arranged such that about 1/5 of the long side of the rectangle is the distance of the minimum non-detection range Y1 (Y2). I am letting. The maximum distance to be shifted is a distance obtained by adding the range Z of the magnetic force exerted so that the magnetic sensor can be detected from the end to the outside of the rectangular long side length of the magnetic material mark.

  As a result, when viewed from the transport direction, the non-detection ranges Y1, Y2 of the magnetic marks 21A, 21B are overlapped with the detectable range of the other magnetic mark, and one detectable range X1 as a set. The entire range from one end to the other end X′2 of the other detectable range is the entire detection range for the magnetic sensor.

  Here, FIG. 2 shows a part of an explanatory diagram of the mark detection system when matching the form of the present invention. FIG. 2 shows a part of the mark detection system 31. For example, a mark detection unit 33 is arranged at a predetermined position in the conveyance direction of the conveyance unit 32 for belt conveyance, and the mark detection unit 33 includes the magnetic materials described above. The magnetic sensors 34A to 34F corresponding to the mark sets 21 to 26 are provided.

  On the other hand, the sealing body 41 is sequentially transported on the transport means 32, and the sealing body 41 is provided with a window 42 and a form body 11 having an individual form body shown in FIG. It is enclosed. That is, the magnetic sensor 34A is made to correspond to the magnetic mark set 21 formed on the form body 11, the magnetic sensor 34B is made to correspond to the magnetic mark set 22, and the magnetic sensor 34C to the magnetic mark set 23. The magnetic sensor 34D corresponds to the magnetic mark set 24, the magnetic sensor 34E corresponds to the magnetic mark set 25, and the magnetic sensor 34F corresponds to the magnetic mark set 26. It is.

  FIG. 3 is an explanatory diagram of mark detection of the form body in FIG. Here, description will be made assuming that only the magnetic mark set 21 (21A, 21B) of the form 11 shown in FIG. 1 is magnetized, but it may be magnetized in combination with another magnetic mark set. FIG. 3A shows the corresponding positional relationship between the magnetic body mark set 21 (magnetized magnetic marks 21A and 21B) of the form body 11 and the magnetic sensor 34A. The form body 11 is transported. When a so-called abare that changes position in the vertical direction occurs, the positional relationship between the magnetic mark set 21 and the magnetic sensor 34A shifts in the vertical direction.

  As shown in FIG. 3B, even if the magnetic sensor 34A is positioned in the non-detection range Y1 of the magnetic mark 21A due to the deviation in the positional relationship, the magnetic sensor 34A is positioned in the detectable range X2 of the magnetic mark 21B. As a result, the magnetic mark 21B is detected.

  Further, as shown in FIG. 3C, even if the magnetic sensor 34A is positioned in the non-detection range Y2 of the magnetic mark 21B due to the deviation of the positional relationship, the magnetic sensor 34A can detect the detection range X of the magnetic mark 21A. Therefore, the magnetic mark 21A is detected.

  Of course, if the magnetic sensor 34A is not located in any of the non-detection ranges Y1 and Y2, both the magnetic marks 21A and 21B will be detected. That is, if a detection circuit is configured to output a detection signal by detecting at least one of the magnetic marks of the set with respect to the magnetic sensor 34A (the same applies to the other magnetic sensors 34B to 34F). Good.

  In this way, even if a so-called abare occurs in the conveyed form body and the position changes in the vertical direction, the corresponding magnetic sensor detects any magnetic material mark magnetized as a set, and is therefore conveyed. The magnetic mark magnetized with respect to the vertical position change of the form body can be reliably detected.

  By the way, in the above-described embodiment, the case where the two magnetic marks are made into a pair of magnetic marks is shown, but three or more magnetic marks may be made into a pair of magnetic marks, and these are taken from the transport direction. It is only necessary to arrange so that the non-detection range of each magnetic mark is positioned within the detectable range of other magnetic marks.

  On the other hand, the form body 11 of the present invention can be adapted to a form body matching system for determining whether or not the form body 11 enclosed in the sealing body 41 is genuine as mark detection by the mark detection system 31 in the above embodiment. it can. For example, as described above with reference to FIGS. 3 and 4, when the form 11 is bent and sealed in the sealing body 41, the address, name, and identification code are displayed on the window 42. When the form 11 is sealed in the sealing body 41, the identification code exposed from the window 42 is read and recognized by the image pickup means, and the recognized identification code and the magnetic sensor 34A are printed. Matching is performed with the positions of the magnetic body mark groups 21 to 26 detected at .about.34F. Note that the form 11 enclosed in the sealing body 41 may be single or plural.

  As another example of adaptation, a plurality of forms 11 can be collated and, for example, sealed in a sealed body or adapted to a collation system such as bookbinding. For example, a plurality of magnetic mark sets 21 to 26 are formed on the plurality of form bodies 11 as described above, and among the magnetic mark sets 21 to 26 of the form body 11 to be collated, the magnetic mark sets at the same position are formed. The magnets 21 to 26 are magnetized, the magnetic mark sets 21 to 26 magnetized at the time of collation are detected, and it is determined whether or not a regular form is collated at that position. In this case, such a state can be detected as an error even when the collation target form is upside down or turned over.

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