Description

  The present invention relates to a mark detection system for detecting a magnetized magnetic mark out of magnetic marks formed on a form body in a non-contact manner.

  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 each form when inspecting the form 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. Various types of marks and codes for matching attached to such a form are proposed. For example, when a reference symbol (bar code) is printed on a sheet with ink containing metal or metal powder and read by an inspection device using X-ray transmission (Patent Document 1), or when an alternating magnetic field exceeding the coercive force of its own is applied A technique for providing a detection mark by printing or applying an ink or paint containing a ferromagnetic powder that causes sharp magnetization reversal to the contents stored in a packaging box is proposed (Patent Document 2). .

  In addition, each individual form of the collation form is made of a magnetic material with a corresponding mark pattern detected by a magnetic sensor corresponding to the magnetic quantity for matching inspection. The applicant of the present application has proposed that the respective mark patterns are later detected by the magnetic sensor and matched (patent document 3).

  Here, FIG. 6 shows an explanatory diagram of an example of a form that is a premise of the present invention, and FIG. 7 shows an explanatory diagram of mark detection of the form in FIG. FIG. 6 shows a plurality of forms to be sealed in the sealing body. In FIG. 6A, 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 103A to One form body 103 constituted by 103C is continuous, and is printed on any one of the individual form bodies 103A to 103C with ink mixed with magnetic powder in the mark forming region at one end thereof. For example, five magnetic marks 111 </ b> A to 111 </ b> E are connected in a direction perpendicular to the transport direction (width direction), and any one of the magnetic marks 111 </ b> A to 111 </ b> E 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. 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 one of the magnetic marks 111 </ b> A to 111 </ b> E 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.

  In the matching, as shown in FIG. 7, after the sealing step, the identification code which is conveyed to the imaging position (not shown) by the conveying means 121 and is exposed from the window 106 is imaged and recognized, and further conveyed to the mark detection position. When the mark detection unit 122 detects any of the magnetized magnetic marks 111A to 111E, matching is performed at the recognized identification code and the detected position of the magnetic mark. is there.

  In other words, the mark detection unit 122 corresponds to the magnetic marks 111A to 111E of the form 103 enclosed in the conveyed sealing body 105 by the magnetic sensors 131 to 135, respectively. By detecting 131 to 135, the position (mark pattern) of the magnetic mark is determined.

Japanese Patent No. 3098557 JP 2003-285808 A JP 2008-074556 A

  However, as shown in FIG. 7, when the form body 103 is transported on the transport means 121, the form body 103 causes a so-called “abare” in the sealing body 105 in a direction perpendicular to the transport direction (width direction). The magnetic sensors 131 (132 to 135) that are fixed and arranged cannot read the original magnetic marks 111A to 111E with the corresponding original magnetic sensors, or other magnetic sensors to be read. There is a problem that reading is likely to occur.

  Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a mark detection system that can reliably detect a magnetized magnetic mark even with respect to a slip of a form in a sealed body. .

  In order to solve the above-mentioned problem, in the invention of claim 1, in the width direction when a plurality of magnetic marks are later conveyed to a form body for each individual content enclosed in a sealing body and delivered for each individual destination. A mark detection system that is formed in a continuous state, magnetizes a predetermined magnetic mark to distinguish individual destinations of the form, and detects the magnetized magnetic mark. One of the body marks is magnetized to be a reference magnetic body mark, and is magnetized to distinguish any one or all of the other magnetic body marks. , Provided with a magnetic sensor having more magnetic sensors than the number of the magnetic body marks, and provided on the conveyance of the sealing body in which the form body is enclosed, and against the magnetic body mark due to the shift in the width direction in the sealing body of the form body Arrange any magnetic sensor to support And a sensor identification table that associates a magnetic sensor that should detect the reference magnetic body mark and a magnetic sensor corresponding to a magnetic body mark other than the reference, with reference to the sensor identification table, And a detection processing means for detecting all the magnetic marks magnetized by specifying another magnetic sensor based on the magnetic sensor detecting the magnetic mark.

  According to a second aspect of the present invention, the sensor specifying table is a magnetic sensor at a predetermined position or a magnetic position close to a predetermined magnetic sensor side as a case where the adjacent magnetic sensor detects the reference magnetic body mark. The sensor is associated with a magnetic sensor corresponding to a magnetic mark other than the reference.

  According to the present invention, the form body is magnetized so that one of the plurality of magnetic marks is a reference magnetic mark, and the individual destination is distinguished from any or all of the other magnetic marks. In order to achieve this, the sensor is provided with a sensor identification table in which a magnetic sensor that should detect a reference magnetic mark and a magnetic sensor corresponding to a magnetic mark other than the reference is associated with the magnetic sensor. When the magnetic mark magnetized by the mark detection unit is detected, another magnetic sensor is specified and magnetized based on the magnetic sensor detecting the reference magnetic mark with reference to the sensor specifying table By adopting a configuration that detects all the magnetic marks, it can detect other magnetic substances magnetized by other magnetic sensors by detecting the reference magnetic mark even when the form is displaced in the sealed body. Because it can respond, in which can reliably detect the magnetized magnetic mark.

Hereinafter, the best embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a part of the mark detection system of the present invention. FIG. 1 shows a part of the mark detection system 11. For example, a mark detection unit 13 is provided at a predetermined position on the conveying unit 12 for belt conveyance, and the mark detection unit 13 includes a magnetic mark (described later). 23A-23E) more magnetic sensors 14-1 to 14-11 than the number of magnetic sensors 14-1 to 14-11. The sensors are arranged to correspond (described later). The magnetic sensor 14 can be realized by a magnetic impedance effect sensor, a flux gate magnetic sensor, a magnetoresistive effect (MR) sensor, or the like.

  On the other hand, the sealing body 21 is sequentially transported on the transporting means 12, and the sealing body 21 is provided with a window portion 21A, which is similar to the form body shown in FIGS. 6A and 6B described above. The form body 22 is enclosed. That is, a plurality of rectangular magnetic marks 23A to 23E are formed in the form body 22 in a continuous state in a direction perpendicular to the transport direction (width direction) when transported later. Magnetization to be a magnetic mark is applied, and magnetization is applied to any or all of the other magnetic marks in order to distinguish the individual points. Here, for example, the magnetic material mark 23A is magnetized to serve as the reference magnetic material mark 23A.

  Here, assuming that the width of the sealing body 21 is We and the width of the form body 22 is Wf, the deviation amount of the form body 22 due to an ablation within the sealing body 21 is [We−Wf]. That is, the magnetic sensors 14 that cover the width of the sealing body 21 are arranged. In this case, when the detection range of each of the magnetic sensors 14-1 to 14-11 is Sw, the magnetic force range of the magnetic marks 23A to 23E when magnetized is Mw, and the arrangement interval is Mi, the magnetic sensor and the magnetic substance The relationship with the mark is [Sw ≧ Mw] and [Sw <Mi], and accordingly, the number of magnetic sensors (Sn) is [We / Sw] with respect to the width We of the sealing body 21. .

  Next, FIG. 2 shows an explanatory diagram of detection processing means in the mark detection system of the present invention. In FIG. 2 (A), the detection processing means 31 is connected to the magnetic sensors 14, and includes a control means 41, a bus 42, an interface (IF) 43, a ROM 44, a RAM 45, and a pattern recognition means 46 as appropriate. The pattern recognition unit 46 includes a sensor identification table 47.

  The control means 41 controls the system in an integrated manner by algorithm processing, and a program for this purpose is provided in the ROM 44. The RAM 45 is a memory for temporary storage, and is a semiconductor memory or a hard disk that is virtually set as a work area for various programs such as a verification memory area.

  The pattern recognition means 46 includes a sensor specifying table 47 that associates a magnetic sensor that should detect a reference magnetic mark and a magnetic sensor corresponding to a magnetic mark other than the reference, with reference to the sensor specifying table 47, It includes detection processing means for detecting all the magnetic marks magnetized by specifying another magnetic sensor based on the magnetic sensor that has detected the reference magnetic mark, and is magnetized by the magnetic sensor 14. This is a program for recognizing a mark pattern based on the combination of magnetic marks, which is developed in the RAM 45 and executed.

  When the mark detection system 11 according to the present invention is applied to a form body matching system, for example, an image pickup means for picking up an address recognized by the window portion 21A of the sealing body 21, an address from the image data, etc. Recognizing means for recognizing, and a recognizing means for collating the recognized address with the mark pattern recognized from the magnetized magnetic mark of the individual form to determine whether or not the above-mentioned matching is performed. is there.

  An example of the sensor identification table 47 is shown in FIG. Since the arrangement interval of the magnetic marks 23A to 23E is Mi and the arrangement interval of the magnetic sensors 14-1 to 14-11 is known, the magnetic substance marks 23A to 23E and the magnetic sensors 14-1 to 14-1 of FIG. 14-11, for example, when the sensor that detects the reference magnetic mark 23A is the magnetic sensor 14-1, the sensors corresponding to the other magnetic marks 23B to 23E are the magnetic sensor 14-3. , 14-5, 14-7, 14-9. As another example, when the sensor that has detected the reference magnetic body mark 23A is the magnetic sensor 14-2, the sensors corresponding to the other magnetic body marks 23B to 23E are the magnetic sensors 14-4, 14-6. 14-8 and 14-10.

  Then, as shown in FIG. 2 (C), the pattern recognition means 46 magnetizes the magnetic marks 23A to 23E (the magnetic marks 23A of the individual forms 22 are magnetized on all the forms 22 so that the reference magnetism is obtained. The magnetization state of the body mark is recognized as a mark pattern in accordance with the detection of the magnetic sensor 14.

  FIG. 3 is an explanatory diagram for identifying the detection sensor for mark detection in the present invention. Here, as described above, among the magnetic marks 23A to 23E formed on the form body 22, the magnetic mark 23A is magnetized to serve as a reference magnetic mark. FIG. 3A shows a case where the form body 22 is shifted to the leftmost end in the figure in the sealing body 21. In this form, the reference magnetic body mark 23A is detected by the magnetic sensor 14-1.

  Then, the pattern recognition means (detection processing means) 46 refers to the sensor identification table 47 shown in FIG. 2B to detect the other magnetic body marks 23B to 23E based on the magnetic sensor 14-1. Magnetic sensors 14-3, 14-5, 14-7, and 14-9 are specified as corresponding sensors. For example, when only the magnetic material mark 23B is magnetized, the magnetic sensor 14-3 detects it, and the other specified magnetic sensors 14-5, 14-7, 14-9 are magnetized. Corresponding to the magnetic marks 23C to 23E that are not performed, but not detected. Therefore, the mark pattern [1] shown in FIG. 2C is recognized by detecting the magnetic marks 23A and 23B.

  FIG. 3B shows a case where the form body 22 is positioned substantially in the center of the sealing body 21. In this form, the reference magnetic body mark 23A is detected by the magnetic sensor 14-2. The Therefore, referring to the sensor identification table 47 shown in FIG. 2B, based on the magnetic sensor 14-2, as sensors corresponding to detecting the other magnetic body marks 23B to 23E, the magnetic sensors 14-4, 14-6, 14-8, and 14-10 are specified. For example, when only the magnetic material mark 23C is magnetized, the magnetic sensor 14-6 detects it, and the other specified magnetic sensors 14-4, 14-8, and 14-10 magnetize. Corresponding to the magnetic marks 23B, 23D, and 23E that are not performed are not detected. Therefore, the mark pattern [2] shown in FIG. 2C is recognized by detecting the magnetic marks 23A and 23C.

  Further, FIG. 3C shows a case where the form body 22 is shifted to the rightmost end in the figure in the sealing body 21. In this form, the reference magnetic body mark 23A is detected by the magnetic sensor 14-3. Is done. Therefore, referring to the sensor identification table 47 shown in FIG. 2B, based on the magnetic sensor 14-3, as sensors corresponding to detecting the other magnetic body marks 23B to 23E, the magnetic sensors 14-5, 14-7, 14-9, and 14-11 are specified. For example, when only the magnetic material marks 23B and 23C are magnetized, the magnetic sensors 14-5 and 14-7 detect, and the other specified magnetic sensors 14-9 and 14-11 Although it corresponds to the magnetic body marks 23D and 23E which are not magnetized, it is not detected. Therefore, the mark pattern [3] shown in FIG. 2C is recognized by detecting the magnetic marks 23A to 23C.

  As described above, since the reference magnetic body mark 23A can be detected by detecting the reference magnetic body mark 23A even with respect to the slip of the form body 22 in the sealing body 21, other magnetic body marks can be dealt with. The mark can be reliably detected.

  Next, FIG. 4 shows an explanatory diagram of a sensor identification table according to another embodiment of the present invention, and FIG. 5 shows an explanatory diagram of detection sensor identification in FIG. This form is a case where the adjacent magnetic sensor detects the reference magnetic mark. In this case, as shown in FIG. 4, the sensor specifying table 47 has a magnetic sensor at a predetermined position (here, referred to as a magnetic sensor 14-1) or a position close to the predetermined magnetic sensor 14-1 side. The magnetic sensor is associated with a magnetic sensor corresponding to a magnetic mark other than the reference.

  For example, as shown in FIG. 5A, when the magnetic sensors 14-1 and 14-2 detect the reference magnetic body mark 23A due to the displacement of the form body 22 in the sealing body 21, the pattern recognition means (detection) The processing means) 46 refers to the sensor identification table 47 shown in FIG. 2B, and, based on the magnetic sensor 14-1 among the magnetic sensors 14-1 and 14-2, the other magnetic body marks 23B to 23B. Magnetic sensors 14-3, 14-5, 14-7, and 14-9 are specified as sensors corresponding to detecting 23E.

  Further, as shown in FIG. 5B, when the magnetic sensor 14-2, 14-3 detects the reference magnetic body mark 23A due to the deviation of the form body 22 in the sealing body 21, the pattern recognition means (detection) The processing means) 46 refers to the sensor identification table 47 shown in FIG. 2B, and, based on the magnetic sensor 14-2 among the magnetic sensors 14-2 and 14-3, the other magnetic body marks 23B to 23B. Magnetic sensors 14-4, 14-6, 14-8, and 14-10 are specified as sensors corresponding to detecting 23E.

  As described above, even when both of the adjacent magnetic sensors detect the reference magnetic mark 23A due to the shift of the form body 22 in the sealing body 21, the magnetism corresponding to the other magnetic marks 23B to 23E is detected. Since the sensor can be specified, by detecting the reference magnetic body mark for any deviation of the form body 22 in the sealing body 21, the other magnetic body magnetized by another magnetic sensor can be used. The magnetic material mark magnetized correspondingly can be reliably detected.
