Description

  The present invention relates to a delivery body in which a predetermined number of forms each having a magnetic mark magnetized on a magnetic body are stacked.

  In recent years, after a form body is enclosed in a sealed body as a delivery body, it is delivered to individual destinations. The sealed body actually contains a form body for each individual destination, or different form bodies are mixed. There is a check to see if there is any. 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. 9 is an explanatory diagram illustrating an example of a form that is a premise of the present invention, and FIG. 10 is an explanatory diagram illustrating detection of the magnetic mark in FIG. FIG. 9A shows a form to be enclosed in a sealing body. In FIG. 9A, the continuous form 101 has marginal parts 102A and 102B formed on both sides in the conveying direction, and the 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. 9B, 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.

  In the matching, as shown in FIG. 10A, the identification code conveyed to the imaging position (not shown) by the conveying means 121 after the enclosing step and imaged from the window 106 is imaged and recognized, 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.

  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. 10B, 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 is minimized (zero) at the switching point between the N pole and the S pole.

  However, as shown in FIG. 10A, when the form body 103 is transported on the transport means 121 and a so-called flutter occurs in the vertical direction, if the magnetic mark and the magnetic sensor approach due to the flutter, the magnetic mark The output value of the magnetic sensor expands in the direction away from both ends of the magnetic field, and it is difficult to determine which detection is caused by affecting the adjacent magnetic mark (non-magnetized mark) or magnetic mark. is there. In addition, there is a problem in that a non-magnetized mark that is not magnetized may be affected by an external magnetic field and may be erroneously detected. Furthermore, there is a problem that only one piece of information is given to one magnetic mark and the degree of freedom is low.

  Accordingly, the present invention has been made in view of the above problems, and improves the degree of freedom of magnetic marks provided for a plurality of stacked form bodies while avoiding the influence of an external magnetic field, and enables delivery to be reliably detected. The purpose is to provide a body.

  In order to solve the above-mentioned problems, in the invention of claim 1, a predetermined number of form bodies each having a magnetic mark magnetized on a magnetic body are stacked, and the magnetic force from the magnetic mark is detected in a non-contact manner by a corresponding magnetic sensor. The magnetic mark is a magnet that is continuous with two magnetization directions magnetized in different directions in the longitudinal direction of the magnetic body provided in a single unit for each of the stacked form bodies. It is configured to have at least one detection region to be detected by the magnetic sensor at the boundary portion in the magnetization direction.

In the inventions of claims 2 to 4, "the respective form bodies are superimposed at positions where the detection areas of the magnetic marks do not overlap each other between the form bodies",
`` Each form body has a configuration in which detection areas of the same magnetization direction of the magnetic mark are overlapped with each other between the form bodies '',
“Configuration having at least one detection region to be detected by the magnetic sensor in the overlapped state of each form body and canceling the magnetic force by overlapping the detection regions of different magnetization directions of the magnetic mark at other positions” It is.

  According to the present invention, a predetermined number of forms each having a magnetic mark magnetized on a magnetic body are stacked, and the magnetic marks are each provided in a single unit for each stacked form body in the longitudinal direction. The two magnetizing directions are magnetized in different directions to be continuous and have at least one detection region to be detected by the magnetic sensor at the boundary portion of the different magnetization directions. Since a detection region where the magnetic force is increased is formed at the boundary portion of different magnetization directions that are continuously magnetized with respect to the magnetic material, portions other than the detection region are affected by the external magnetic field. It is difficult to receive and avoids false detection. By superimposing these forms, it is possible to control the number of detection areas that can be detected and further increase the magnetic force. Freedom can be improved in the information addition, also those that can reliably detect the mark portion of the detection area.

Hereinafter, the best embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a configuration diagram of a delivery body according to the present invention. In FIG. 1A, the delivery body 11 is configured by overlapping individual form bodies 12 and 13 respectively. Here, a case where two forms are overlapped will be described, but the same applies to three or more forms.

  In the form body 12, a single magnetic mark 21 is formed at a predetermined position in the entire width direction with respect to the longitudinal direction. For example, when the width direction with respect to the longitudinal direction is 99 mm (1/3 of the length in the longitudinal direction of the A4 size), the magnetic mark 21 is formed with a width of 2 mm. The magnetic mark 21 is formed of a magnetic material, for example, by printing or the like. By a magnetic recording head described in FIG. 2 to be described later, as shown in FIG. A boundary region having different magnetization directions is a detection region 23A that is detected by a magnetic sensor described later.

  The form body 13 is, for example, the same size as the form body 12, and a single magnetic mark 22 is formed at a portion that is located at the same position as the magnetic mark 21 when superimposed. As shown in FIG. 1C, a detection region 23B is formed at a position different from the detection region 23A by the same method as the magnetic mark 21 as an example. Then, as shown in FIG. 1D, the magnetic marks 21 when the form body 13 is overlaid on the form body 12 are such that the detection areas 23A and 23B are at different positions in the length direction.

  Here, FIG. 2 shows an explanatory diagram of magnetization of the magnetic mark in FIG. In FIG. 2A, a magnetic recording head 31 has a general induction type configuration, and a coil 33 is wound around a core 32, and an end of the core 32 has a minute gap G. By energizing the coil 33, both ends of the gap G become electrodes 34A (N pole, S pole) and 34B (S pole, N pole) according to the polarity, and the magnetization direction is determined.

  When the magnetic recording head 31 as described above causes two magnetization directions to be continuous in different directions in the longitudinal direction by magnetization with respect to the magnetic body 41 formed on the form bodies 12 and 13, FIG. 2, two electrodes 34A and 34B of the magnetic recording head 31 are provided in the direction perpendicular to the longitudinal direction of the magnetic body 41, and the short side of the magnetic body 41 is perpendicular to the electrodes 34A and 34B. More pass.

  For example, as shown in FIG. 2B, when the coil 33 is energized with the electrode 34A as the N pole and the electrode 34B as the S pole and the magnetic body 41 is passed from the short side, the gap G becomes the magnetic body. When 41 passes the position to be the detection region 23, it is magnetized in the magnetization direction from the N pole to the S pole. Thereafter, as shown in FIG. 2C, by reversing the polarity of the electrodes 34A and 34B, the end portion or the next polarity reversal is magnetized in the magnetization direction of the S pole ← N pole. A single magnetic mark 42 is formed by being magnetized in two different magnetization directions, and a boundary portion of the different magnetization directions becomes the detection region 43.

  Next, FIG. 3 shows an explanatory diagram of the magnetization length of the magnetic mark in FIG. In FIG. 3A, the magnetic recording head 31 shown in FIG. 2 continuously magnetizes the magnetization directions different from each other (in FIG. 3, the case where S pole ← N pole and N pole → S pole are made continuous). The magnetic force of the magnetic mark 42 is a value obtained by superimposing (adding) each other's magnetic force in the adjacent adjacent poles (N, N). In the (S, S) portion, the values are one by one. A magnetic force is detected by the magnetic sensor 44 shown in FIG. 3B as the overlapped portion as a detection region 43, and a corresponding output signal is obtained.

  For example, a magnetic material 42 having a width of 2 mm and a magnetic material having a holding force of 1500 (Oe: unit Oersted) having a length (magnetization length) shown in FIG. The output signal value (2.5 V as a reference value) at a position of 3 mm in height by a magnetic sensor (MI sensor manufactured by Aichi Micro Intelligent) 44 magnetized with a residual magnetic flux density of Gauss) is shown in FIG. (C) and (D).

  That is, as shown in FIGS. 3C and 3D, the output signal value increases proportionally as the detection region is farther (longer) from the end, and becomes saturated from about 6 mm from the end. Measured. When this is applied, the maximum output signal value (magnetic force) can be obtained by forming the magnetization length beyond 6 mm from the end.

  Therefore, FIG. 4 shows a corresponding explanatory view of the magnetic sensor with respect to the magnetic mark of the delivery body of FIG. 1, and FIG. 5 shows an explanatory view of magnetic sensor detection of the magnetic mark in FIG. 4A and 4B, when the matching inspection is performed on the delivery body 11 in which the form bodies 12 and 13 are overlaid and the magnetic marks 21 and 22 are overlaid, the upper side of the overlaid magnetic marks 21 and 22 (above described above). Detection is performed by the magnetic sensor group 51 at a similar height of 3 mm). Here, the magnetic marks 21 and 22 are the same magnetic marks 21 and 22 as shown in FIG. 1, and are magnetized with a residual magnetic flux density of 4000 (G) in a magnetic ink having a holding force of 1500 (Oe). In the following description, it is assumed that the detection areas 23A and 12B are arranged and formed.

  In the magnetic sensor group 51, for example, five magnetic sensors 51A to 51E similar to the magnetic sensor 44 described in FIG. 3B are arranged at equal intervals, and correspond to the positions of the magnetic sensors 51A to 51E. Thus, detection areas 23A and 23B are formed in the magnetic marks 21 and 22, respectively. That is, as shown in FIG. 4B, the detection area 23A of the magnetic mark 21 is detected by the magnetic sensor 51B and the detection area 23B of the magnetic mark 22 is detected by the magnetic sensor 51D. It is something to detect with.

  Specifically, the output signals of the magnetic sensors 51A to 51E are based on 2.5V, and the magnetic sensor 51B detects and outputs the detection region 23A of the S and S poles in the magnetic mark 21 as shown in FIG. The signal becomes a peak value, and the magnetic sensor 51D detects the S and S pole detection regions 23B of the magnetic mark 22 as shown in FIG. That is, as shown in FIG. 5C, two peak value output signals can be obtained in a state where the outputs of the magnetic sensors 51B and 51D in the magnetic sensor group 51 with respect to the stacked magnetic marks 21 and 22 are overlapped. Is. Since the other sensors 51A, 51C, 51E do not detect magnetic force, no output peak occurs.

  It should be noted that the magnetized portion of the magnetic mark 22 overlapped when detecting the detection region 23A in the magnetic sensor 51B is not an end (magnetic pole) and has no effect. Similarly, the magnetized portion of the magnetic mark 21 overlapped when detecting the detection region 23B in the magnetic sensor 51D is not an end portion (magnetic pole) but has no influence.

  In this way, a detection region in which the magnetic force is increased is formed at the boundary portion of different magnetization directions that are continuously magnetized with respect to a single magnetic material in one form. The signal can be easily identified by the magnetic sensor, and portions other than the detection region are not easily affected by the external magnetic field, thereby preventing erroneous detection. Further, as described above (FIG. 9), since the magnetic mark is not a plurality but a single one, it is difficult to be affected by the adjacent magnetic mark, so that the detection area can be made closer and the amount of mark information is increased. It is something that can be done. Further, by superposing these forms, it is possible to control the number of detection areas that can be detected as a whole, and at the same time, it is possible to improve the degree of freedom of information assignment to the magnetic marks.

  Next, FIG. 6 shows an explanatory diagram of another magnetization mode for the magnetic mark in FIG. FIG. 6A shows the S and S pole detection regions 23A and 23B of the same magnetic direction of the magnetic marks 21 and 22 overlapped with each other between the forms 12 and 13. By superposing the S and S poles of the same magnetization direction of each of the magnetic marks 21 and 22, the magnetic force is superimposed (added), and the magnetic force can be further increased. An output signal having a large peak value can be obtained by detecting the overlapped detection areas 23A and 23B with the magnetic sensor 51C, and the identification of the signal and the avoidance of erroneous detection can be achieved.

  Further, in FIG. 6B, at least one detection region to be detected by the magnetic sensor is formed in the overlap state of each form body, and the magnetic force is generated by overlapping the detection regions of different magnetization directions of the magnetic marks at other positions. The configuration is such that it cancels out. That is, the detection region 23A-1 for the S and S poles and the detection region 23A-2 for the N and N poles are formed on the magnetic mark 21, while the magnetic mark 22 is positioned so as to overlap the detection region 23A-2. The S and S pole detection regions 23B are formed.

  That is, FIG. 6B shows a state in which the output of the magnetic sensor 51B and the output of the magnetic sensor 51D are overlapped, and an output signal corresponding to the detection region 23A-1 of the magnetic mark 21 is obtained by the magnetic sensor 51B. In the magnetic sensor 51D, the magnetic force of the detection area 23A-2 of the N and N poles of the magnetic mark 21 and the magnetic force of the detection area 23B of the S and S poles of the magnetic mark 22 cancel each other. It is.

  In this way, it is possible to overlap the detection areas of different magnetization directions to cancel the magnetic force, and to control the number of detection areas that can be detected as a whole of the overlapping state, and to freely apply information to the magnetic mark. The degree can be improved.

  Next, FIG.7 and FIG.8 shows explanatory drawing of the other form of the delivery body in this invention. The delivery body 11 of the above embodiment is a state in which the individual form body 12 and the form body 13 are overlapped. In this embodiment, the delivery form 11 is folded in two (FIG. 7), and the three pieces are folded and folded. It is configured as a stacked form (FIG. 8).

  That is, in FIG. 7A, the form body 12A and the form body 13A are continuous by the folding line 62, and the magnetic mark 61 that overlaps the folding line 62 is formed as a single unit. For example, it becomes the same form as the delivery body 11 shown in FIG. 1 by making the whole into A4 size and folding it in the longitudinal direction.

  As shown in FIG. 7B, the magnetic mark 61 forms, for example, an S / S pole detection area 23A in the form body 12A, and an S / S pole detection area 23B in the form body 13A. It is formed at a position overlapping the detection region 23A by folding with the folding line 62. That is, the detection area 23A and the detection area 23B are overlapped with each other in a state where the form bodies 12A and 13A are folded in two at the fold line 62, and the form similar to that in FIG.

  In this way, since the two folding lines 62 are overlapped by a predetermined folding line 62, positioning of the overlapping detection areas can be ensured, and as a result, a plurality of forms stacked while avoiding the influence of the external magnetic field. The degree of freedom of the magnetic mark provided on the body can be improved and can be reliably detected.

  Next, FIG. 8A shows the delivery body 11 overlapped by three pieces of folds. The form bodies 12A, 13A, and 14A are continuously connected by the fold lines 62A and 62B, and are overlapped by the fold lines 62A and 62B. A single magnetic mark 61A is formed. Then, the form body 13A is folded on the form body 12A by folding with the folding line 62A, and the form body 14A is folded on the form body 13A by folding with the folding line 62B. It has been made.

  As shown in FIG. 8B, the magnetic mark 61A forms, for example, S and S pole detection areas 23A in the form body 12A, and the form body 13A folds the N and N pole detection areas 23B. The detection area 23A is formed so as not to overlap with the detection area 23A when folded by 62A, and the detection area 23C of the S and S poles, for example, is formed at a position overlapping the detection area 23A by folding along the folding line 62B. is there. That is, the detection area 23B is positioned independently by folding the folding lines 62A and 62B, and the detection area 23A and the detection area 23C are overlapped. The magnetic sensor 51B detects the detection area 23B, and the magnetic sensor 51D The detection regions 23A and 23C are detected by the superimposed magnetic force.

  As described above, the detection regions can be overlapped or positioned independently by overlapping them in three by the predetermined folding lines 62A and 62B. As a result, the influence of the external magnetic field is the same as described above. Thus, the degree of freedom of magnetic marks provided for a plurality of form bodies that are stacked while avoiding the above can be improved, and detection can be made reliably.

  The delivery body of the present invention is suitable when a magnetic mark detected by a magnetic sensor is formed for matching a delivery body composed of a plurality of forms.
