Description

  The present invention relates to a management apparatus used for management of a roll-shaped sheet material such as roll paper, and a management system using the same.

  For example, in an image forming apparatus such as a large-sized printer, a sheet material such as paper, film, or cloth, which is a printing medium, is a rolled sheet in which a sheet material is wound around a core material made of cylindrical paper or the like. It is supplied in the form of a material (so-called roll paper when the sheet material is paper). Such a roll-shaped sheet material is prepared in a plurality of types, sizes, and the like of the sheet material and can be used properly according to the application. Further, it is often performed that a roll-shaped sheet material in use is removed from the printer and stored, and the roll-shaped sheet material is shared by a plurality of printers. Therefore, in the roll-shaped sheet material, it is necessary to appropriately manage the remaining amount, type, size, and the like of the sheet material.

  Therefore, the following Patent Document 1 discloses a communication control device for communication between a memory that is attached to a roll paper and stores information related to the roll paper and an external device as an apparatus used for managing the roll sheet material. Has been. The communication control device includes a member mounted on the roll paper, a storage unit that is provided in the member, stores identification information of the member, and an identification information that is provided in the member and is stored in the storage unit.

  However, in the conventional communication control apparatus, it is necessary to supply all the information related to the roll paper stored in the memory provided in the member mounted on the roll paper from the outside to the member. A part of the information relating to the roll paper stored in the paper cannot be acquired autonomously on the member side.

  For this reason, in the conventional communication control apparatus, roll paper cannot always be managed sufficiently adequately. For example, the remaining amount of roll paper is acquired by subtracting the roll paper feed length from the length before roll paper feed in the printer using the roll paper, and the printer controls the communication control device. Have been supplied. Therefore, the printer does not have a function of acquiring the remaining amount of roll paper, or the printer does not have an interface compatible with the communication control device even if the printer has a function of acquiring the remaining amount of roll paper. If this is the case, the remaining amount of the printer cannot be supplied from the printer to the communication control device, so that the roll paper cannot be properly managed.

  Further, for example, when the roll paper is carried, an impact may be applied to the roll paper. If the impact is large, the quality of the roll paper will be deteriorated because a part of the roll paper will be dented or damaged. However, since the conventional communication control device cannot independently acquire the impact history of the roll paper, it cannot determine whether or not the roll paper has received a large impact, Since it is not possible to select only those that are properly handled so as not to receive the roll, the roll paper cannot be properly managed.

  Furthermore, for example, in order to maintain the quality of the roll paper, when storing the roll paper, the temperature and humidity are kept at appropriate values in the warehouse, etc. As a result, the roll paper may be stored at an inappropriate temperature or humidity. However, since the conventional communication control device cannot autonomously acquire the temperature history and humidity history of the roll paper, it is determined whether or not the roll paper is stored at an appropriate temperature and humidity. Or knowing when the temperature or humidity has become inappropriate, the roll paper cannot be managed properly.

  Hereinafter, a management apparatus and a management system according to the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic perspective view showing a management apparatus 1 according to an embodiment of the present invention and a roll-shaped sheet material 2 on which the management apparatus 1 is mounted. 2 and 3 are schematic sectional views showing the management device 1 in FIG. 1 and the roll-shaped sheet material 2 in FIG. 1, respectively. FIG. 2 shows a state where the management apparatus 1 is not mounted on the roll-shaped sheet material 2, and FIG. 3 shows a state where the management apparatus 1 is mounted on the roll-shaped sheet material 2.

  In this example, the roll-shaped sheet material 2 is composed of a core material 11 made of cylindrical paper and the like, and a sheet material 12 such as paper, film or cloth wound around the core material 11. 1 to 3, A <b> 1 indicates the central axis of the roll-shaped sheet material 2 (that is, the central axis of the core material 11). In this example, the roll sheet material 2 is used in a large printer (inkjet printer or the like) (not shown), and the sheet material 12 is a printing medium. For example, the width of the sheet material 12 in the central axis A1 direction is about 1000 mm, and the initial length of the sheet material 12 is several hundreds of meters. However, the use of the roll-shaped sheet material to which the management device according to the present invention is attached and which is to be managed is not limited to a printing medium for a large printer.

  As shown in FIGS. 1 to 3, the management device 1 according to the present embodiment includes a main body member 21 that is attached to the roll-shaped sheet material 2. The main body member 21 includes a tapered cylindrical tapered portion 21a and an annular flange portion 21b formed at the large-diameter side end of the tapered portion 21a. 1 to 3, A2 indicates the central axis of the main body member 21 (central axes of the tapered portion 21a and the flange portion 21b). The main body member 21 is formed with a tapered through hole 21c along the central axis A2. Using this through hole 21c, the roll sheet material 2 on which the management device 1 is mounted can be attached to the printer. The through hole 21c is not necessarily a tapered hole, and may be a straight hole. A member (not shown) having the same outer shape as that of the main body member 21 is rolled as necessary so that the roll-shaped sheet material 2 on which the management device 1 is mounted can be appropriately attached to the printer. It may be mounted on the opposite side of the sheet material 2.

  In FIG. 1 to FIG. 3, in order to facilitate understanding, the main body member 21 is hatched as if it were solid, but actually, the main body member 21 constitutes a casing. The management device 1 has an internal space for providing elements to be described later. 2 and 3, only a mounting detector 22 and a rotating plate 41, which will be described later, are shown in FIG. 2 and FIG. 3 among the elements of the management device 1 provided on the main body member 21.

  Since the outer diameter of each part of the taper portion 21a is determined according to the inner diameter of the core material 11, the taper portion 21a is press-fitted into one end portion of the core material 11 as shown in FIG. While being firmly attached to the roll-shaped sheet material 2, the main body member 21 can be detached from the roll-shaped sheet material 2. When the main body member 21 is attached to the roll-shaped sheet material 2, the central axis A2 of the main body member 21 coincides with the central axis A1 of the roll-shaped sheet material 2, as shown in FIG. Since the tapered portion 21a has a tapered shape, the main body member 21 can be firmly attached to the roll-shaped sheet material 2 even if the inner diameter of the core material 11 changes to some extent. But the structure for mounting | wearing the roll-shaped sheet material 2 with the main body member 21 is not restricted to the press-fit structure by the taper part 21a, You may employ | adopt another structure. In addition, it is preferable that the main body member 21 can be detachably attached to the roll sheet material 2 so that the management apparatus 1 can be reused as in the present embodiment. However, the management device according to the present invention may be attached to the roll sheet material in a substantially non-removable manner (for example, attached by bonding with an adhesive).

  In the present embodiment, a known pressure sensor is used as the mounting detector 22 that detects whether or not the main body member 21 is mounted on the roll sheet material 2, and the mounting detector 22 is an outer periphery of the tapered portion 21 a. Is provided. When the main body member 21 is mounted on the roll-shaped sheet material 2, the mounting detector 22 receives a pressure of a predetermined level or higher by the core material 11, while the main body member 21 is not mounted on the roll-shaped sheet material 2. Since the attachment detector 22 does not receive pressure, the attachment / non-attachment of the main body member 21 to the roll-shaped sheet material 2 can be detected. However, the mounting detector 22 is not necessarily limited to the pressure sensor, and for example, a so-called micro switch or the like may be used.

  FIG. 4 is a block diagram showing a schematic configuration of the management apparatus 1 in FIG. In addition to the main body member 21 and the mounting detector 22 described above, the management device 1 according to the present embodiment includes a CPU 23, a memory 24, and a time measuring unit 25 that measures the current time (for example, year / month / day / hour / minute).

The main body member 21 is disposed.

  The temperature detector 33 and the humidity detector 34 detect the temperature and humidity in the vicinity of the roll-shaped sheet material 2 directly or indirectly when the main body member 21 is mounted on the roll-shaped sheet material 2, respectively. The main body member 21 is provided.

  The impact detector 35 is provided on the main body member 21, and when the main body member 21 is mounted on the roll-shaped sheet material 2, its radial direction (direction orthogonal to the central axis A <b> 1) with respect to the roll-shaped sheet material 2. An impact of a predetermined level or more applied is detected. As the impact detector 35, for example, a biaxial acceleration sensor is used, and is provided in the main body member 21 so that two detection axes orthogonal to each other are located in a plane orthogonal to the central axis A2 of the main body member 21. It is done. However, the impact detector 35 is not limited to an acceleration sensor.

  In the present embodiment, the rotation amount detection unit 36 has an annular rotation plate 41 shown in FIGS. 2 and 3. The flange of the main body member 21 so that the central axis of the rotation plate 41 coincides with the central axis A2 of the main body member 21 and is rotatable relative to the main body member 21 around the central axis A2. It is provided in the part 21b. Although not shown in the drawing, for example, a bearing (not shown) from which the shaft has been removed is arranged in the flange portion 21b, and one of the inner ring and the outer ring is used. Is fixed with respect to the main body member 21, while the rotation plate 41 is fixed with respect to the other raceway ring so that the rotation plate 41 is rotatable relative to the main body member 21. it can.

  FIG. 6 is a schematic cross-sectional view schematically showing the rotation plate 41, the light emitters 42a and 43a, the light receivers 42b and 43b, and the weight 44 that constitute a part of the rotation amount detection unit 36. FIG. 7 is a schematic view taken along the line KK in FIG.

  The light emitter 42 a and the light receiver 42 b are disposed so as to sandwich the rotating plate 41 and are fixed to the main body member 21. Light emitted from the light emitter 42a and passing through the rotating plate 41 is received by the light receiver 42b. The light emitter 43 a and the light receiver 43 b are also arranged so as to sandwich the rotating plate 41 and are fixed to the main body member 21. The light emitted from the light emitter 43a and passing through the rotating plate 41 is received by the light receiver 43b. The light emitter 42a and the light receiver 42b are disposed at a position farther from the central axis A2 than the light emitter 43a and the light receiver 43b.

  In the present embodiment, a transparent plate is used as the rotating plate 41. On the rotating plate 41, a plurality of light-shielding scales 52 are formed at equiangular pitches (45 ° pitch in the example shown in FIG. 7) at circumferential positions corresponding to the light emitters 42a and the light receivers 42b. Has been. Further, on the rotating plate 41, a plurality of light-shielding scales at the same equiangular pitch (45 ° pitch in the example shown in FIG. 7) at circumferential positions corresponding to the light emitters 43a and the light receivers 43b. 53 is formed. In the present embodiment, the angular position of the light emitter 42a and the light receiver 42b with respect to the central axis A2 and the angular position of the light emitter 43a and the light receiver 43b with respect to the central axis A2 are the same, while the angular position of the scale 52 and the scale 53 Is shifted by a predetermined phase angle. Therefore, the two-phase pulses of the number of pulses corresponding to the rotation angle from the light receivers 42b and 43b, the phase relationship of which differs depending on the relative rotation direction of the rotating plate 41 with respect to the main body member 21. A pulse is obtained. A light-shielding plate may be used as the rotation plate 41 and slits may be formed as the scales 52 and 53. In the present embodiment, the rotation amount detection unit 36 is a phase discrimination circuit (not shown) that discriminates the rotation direction by discriminating the phases of the two-phase pulses in the same manner as a general incremental rotary encoder. And an up / down counter (not shown) that counts up or down the number of pulses of the two-phase pulses according to the discrimination result in the rotation direction. The up / down counter is reset when the rotation amount measurement starts. The count value of the up / down counter indicates the amount of rotation of the rotation plate 41 relative to the main body member 21 from the rotation position of the rotation plate 41 relative to the main body member 21 at the start of measurement.

  And in this Embodiment, as shown in FIG.6 and FIG.7, the weight 44 is being fixed to one place of the rotation board 41 which is a location which does not interfere with light-emitting device 42a, 43a. Therefore, as long as the central axis A2 does not coincide with the vertical direction, even if the main body member 21 rotates about the central axis A2, the weight 44 of the rotating plate 41 becomes the lowest position in the vertical direction by the weight 44. Further, the rotation plate 41 rotates about the central axis A <b> 2 relative to the main body member 21. Therefore, when the main body member 21 is mounted on the roll-shaped sheet material 2, the count value of the up / down counter becomes a rotation amount detection signal indicating the rotation amount of the roll-shaped sheet material 2 around the central axis A1.

  In addition, when using the roll-shaped sheet material 2 in a printer etc., it is sent out from the sheet material 12 from the roll-shaped sheet material 2, but when removing the roll-shaped sheet material 2 in the middle of use, for example, 1 m to 2 m from the roll In some cases, the sheet material 12 is cut at a portion where the sheet material has been fed out, and the portion of the sheet material 12 fed from the roll that has been fed about 1 m to 2 m is rewound. In the present embodiment, the rotation amount is obtained by counting up and down depending on the rotation direction of the roll-shaped sheet material 2, so that the rotation amount detection signal is generated even when rewinding about 1 m to 2 m as described above. The amount of consumption of the sheet material 2 is accurately reflected, and as a result, the remaining amount of the sheet material 12 of the roll-shaped sheet material 2 can be accurately acquired.

  The configuration of the rotation amount detection unit 36 is not necessarily limited to the configuration described above.

  In the present embodiment, the temperature detector 33, the humidity detector 34, the impact detector 35, and the rotation amount detection unit 36 described above are detection means provided in the main body member 21, and a sheet related to the sheet material 12. Detection means for detecting at least a part of the material-related information or information serving as a basis of the at least a part of the information is configured. However, in the present invention, the detection means is not limited to them, and it is not always necessary to provide all of the temperature detector 33, the humidity detector 34, the impact detector 35, and the rotation amount detector 36. You may only have one, two or three.

  Referring to FIG. 4 again, in the present embodiment, the memory 24 functions as a sheet material related information storage unit that stores sheet material related information related to the roll sheet material 2 on which the main body member 21 is mounted. Also, it functions as an identification information storage unit that stores unique identification information of the management apparatus 1. The identification information is stored in the memory 24 in advance when the management apparatus 1 is manufactured, for example. As the sheet material related information, for example, the production number, product name, production lot, material, thickness, width, initial length, remaining amount (remaining length), state (state) of the sheet material 12 of the roll-shaped sheet material 2 For example, a state in which a predetermined coating is applied, a state in which easy adhesion treatment has been performed, a temperature history, a humidity history, an impact history, and the like of the roll-shaped sheet material 2 can be cited.

  The USB interface 26 and the USB terminal 27 include a USB terminal 27 and USB terminals of various external devices (for example, a printer using the roll-shaped sheet material 2 or a coater for coating the roll-shaped sheet material 2). By connecting a USB cable between them, a command or information by USB input / output is transmitted / received to / from the external device.

  The wireless interface 28 and the antenna 29 are used for transmitting and receiving commands, information, and the like by wireless communication with an external device such as a command device 61 described later.

  FIG. 8 is a block diagram showing a schematic configuration of the command device 61 that constitutes the management system 100 shown in FIG. 9 together with the management device 1 according to the present embodiment. FIG. 9 is a schematic configuration diagram schematically showing the management system 100 according to the embodiment of the present invention.

  As shown in FIG. 9, the management system 100 includes a plurality of management devices 1 and a command device 61. FIG. 9 shows a situation where a plurality of roll-shaped sheet materials 2 to which the management apparatus 1 is attached are stored in a warehouse or the like. The command device 61 is used when selecting a roll sheet 2 satisfying a desired condition from the roll sheets 2.

  In the present embodiment, as shown in FIG. 8, the command device 61 includes a CPU 62, a memory 63, a wireless interface 64, an antenna 65 connected to the wireless interface 64, an input / output interface 66, and an input operation unit. 67, a display unit 68, and a bus 69 for connecting the elements 62 to 64, 66. The elements 67 and 68 are connected to a bus 69 via an input / output interface 66. The command device 61 may be configured as a dedicated device, or may be configured using a general-purpose notebook personal computer or the like.

  FIG. 10 is a schematic flowchart showing the operation of the management apparatus 1 described above. When the CPU 23 of the management apparatus 1 starts its operation, first, it is determined whether or not an input from an external device (such as a printer or a coater) via the USB (that is, the USB terminal 27 and the USB interface 26) has been detected. Determine (step S1). If an input from the USB is detected, the process proceeds to step S8. If no input from the USB is detected, the process proceeds to step S2.

  In step S8, the CPU 23 interprets the detected input from the USB. Next, the CPU 23 performs processing (processing including reading of the sheet material related information from the memory 24 or writing of the sheet material related information into the memory 24) according to the result of interpreting the input from the USB in step S8 ( Step S9), and then the process proceeds to Step S2. For example, when the roll-shaped sheet material 2 on which the management apparatus 1 is mounted is set in a printer and the USB terminal 27 is connected to the printer, input from the USB is predetermined sheet material related information (for example, , The CPU 23 requests the sheet material-related information in step S9 to request the sheet material related information in step S9, the product number, product name, production lot, material, thickness, width, remaining amount, state, etc. Read from the memory 24 and output to the printer via USB. Based on the information, the printer can determine, for example, the printing conditions for printing on the sheet material 12 of the roll-shaped sheet material 2. Further, for example, when the roll sheet material 2 on which the management apparatus 1 is mounted is set on the coater and the USB terminal 27 is connected to the coater, input from the USB is predetermined sheet material related information. In the case of a command requesting (for example, the manufacturing number, product name, manufacturing lot, material, thickness, width, remaining amount, etc.) of the sheet material 12, the CPU 23, in step S9, Read from the memory 24 and output to the coater via USB. Based on the information, the coater can determine, for example, coating conditions for coating the sheet material 12 of the roll-shaped sheet material 2. Furthermore, for example, when the roll-shaped sheet material 2 on which the management apparatus 1 is mounted is set on the coater and the USB terminal 27 is connected to the coater, the input from the USB is in the form of a roll. If the information indicates the content of the coating applied to the sheet material 12 of the sheet material 2, the CPU 23 writes the information in the memory 24 as the sheet material related information in step S9.

  In step S <b> 2, the CPU 23 determines whether or not wireless input (input by wireless communication from an external device via the wireless interface 28 and the antenna 29) is detected. In the present embodiment, the wireless input accepts only the wireless input from the command device 61 as an external device. In step S2, the CPU 23 determines whether or not the wireless input from the command device 61 is detected. judge. However, wireless input from other external devices may also be accepted. If a wireless input from the commanding device 61 is detected, the process proceeds to step S10. If a wireless input from the commanding device 61 is not detected, the process proceeds to step S3. The operation after step S10 will be described later together with the operation of the command device 61.

  In step S <b> 3, the CPU 23 determines whether an operation input from the input operation unit 31 is detected. If an operation input is detected, the process proceeds to step S14. If no operation input is detected, the process proceeds to step S4.

  In step S14, the CPU 23 interprets the detected operation input. Next, the CPU 23 performs processing (processing including reading of sheet material related information from the memory 24 or writing of sheet material related information to the memory 24) according to the result of interpreting the operation input in step S14 (step S15). ), The process proceeds to step S4. For example, when the operation input is a command to give predetermined sheet material related information (for example, the manufacturing number, product name, manufacturing lot, material, thickness, initial length, width, etc. of the sheet material 12) and write the information. In step S15, the CPU 23 writes the sheet material related information in the memory 24. The sheet material related information such as the production number, product name, production lot, material, thickness, initial length and width of the sheet material 12 is input by the input operation unit 31 when the management apparatus 1 is mounted on the roll sheet material 2 at the beginning. It is preferable to input. Further, for example, when the operation input is a command to display predetermined sheet material related information, the CPU 23 reads the sheet material related information from the memory 24 and displays it on the display unit 32 in step S15. In this case, the sheet material related information stored in the memory 24 is output to the outside in an output format called display, and the operator can know the sheet material related information by viewing the display.

  In step S <b> 4, the CPU 23 determines whether the mounting state of the management device 1 has changed based on the signal from the mounting detector 20. If it is determined in step S4 that the change has occurred, the process proceeds to step S5. On the other hand, if it is determined in step S4 that the change has not occurred, the process proceeds to step S16.

  In step S <b> 5, the CPU 23 determines whether or not the management apparatus 1 is mounted on the roll sheet material 2 based on a signal from the mounting detector 20. If it is not mounted, the process proceeds to step S6. If it is mounted, the process proceeds to step S7.

  In step S7, the CPU 23 performs a mounting start process. As the mounting start process, the CPU 23 reads the current time from the time measuring unit 25 and writes the time as the mounting start time in the memory 24. Further, as a mounting start process, the CPU 23 starts the operation by starting the power supply to the impact detector 35 and the rotation amount detection unit 36, and further resets the up / down counter of the rotation amount detection unit 36. .

  In step S6, the CPU 23 performs a mounting end process. As the mounting end process, the CPU 23 reads the current time from the time measuring unit 25 and writes the time in the memory 24 as the mounting end time. In addition, as a mounting end process, the CPU 23 ends the operation of the shock detector 35 and the rotation amount detector 36 by terminating the power supply. The effective management period by the management apparatus 1 can be known from the mounting start time and the mounting end time. The mounting start time and the mounting end time written in the memory 24 are, for example, the display unit 32 of the management device 1 or the like according to an instruction by the operation of the input operation unit 31 of the management device 1 or the input operation unit 67 of the command device 61. You may display on the display part 68 of the instruction | command apparatus 61. FIG.

  In step S <b> 16, the CPU 23 determines whether or not the management apparatus 1 is mounted on the roll sheet material 2 based on a signal from the mounting detector 20. If not attached, the process returns to step S1, while if attached, the process proceeds to step S17.

  In step S17, the CPU 23 reads the value of the impact detector 35 (value indicating the level of impact), determines whether or not the value is equal to or greater than a predetermined value (predetermined level). The current time is read from the time measuring unit 25, and the time is written in the memory 24 as the time of the impact. This time becomes an impact history indicating when the roll-shaped sheet material 2 on which the management device 1 is mounted receives an impact of a predetermined level or more. If the value of the impact detector 35 is not equal to or greater than the predetermined value, step S17 is terminated.

  Next, in step S18, the CPU 23 determines whether or not the present time is a predetermined temperature / humidity measurement timing (for example, every hour), and if so, the temperature detector 33 and the humidity. The temperature / humidity value in the vicinity of the roll-shaped sheet material 2 is read from the detector 34, the current time is read from the time measuring unit 25, and the read temperature / humidity value is associated with the read time. 24. These are the temperature history and humidity history of the roll-shaped sheet material 2. If the current measurement timing is not temperature / humidity, step S18 is terminated.

  Next, in step S <b> 19, the CPU 23 reads the rotation amount of the roll sheet material 2 from the rotation amount detection unit 36, and the rotation amount and the initial length of the sheet material 12 of the roll sheet material 2 stored in the memory 24 in advance. The remaining amount of the sheet material 12 is calculated from the thickness and thickness, and this remaining amount is written in the memory 24 as sheet material related information. Then, it returns to step S1.

  Here, the operation of the command device 61 will be described. FIG. 11 is a schematic flowchart showing the operation of the command device 61. In the following description, a part of the operation of the management device 1 (steps S10 to S13 in FIG. 10) will also be described.

  When starting the operation, the CPU 62 of the commanding device 61 first determines whether or not a search condition is input from the input operation unit 31 (step S31). If the search condition is not input, the search condition is input. When the search condition is input, the process proceeds to step S32.

  The search condition is a condition for selecting a desired roll sheet material 2 from a plurality of roll sheet materials 2 in a warehouse or the like, and is an item of sheet material related information stored in the memory 24 of the management apparatus 1. The conditions for one or more items are combined with AND / OR. The search condition is, for example, that the material of the sheet material 12 is OO and the remaining amount is ΔΔm or more.

  In step S <b> 32, the CPU 62 of the instruction device 61 causes the wireless interface 64 and the antenna 65 to output a read instruction wirelessly. At this time, the read command is transmitted to each management device 1 so as to be received indiscriminately. The read command includes, for each management device 1, the sheet material related information of items necessary to determine whether or not the search condition input in step S31 is satisfied, and the identification information of the management device 1. This is a command for reading out from the memory 24 and performing wireless output in association with each other.

  The read command output wirelessly from the commanding device 61 in step S32 becomes the wireless input in step S2 to the management device 1, and the CPU 23 of each management device 1 proceeds to step S10. In step S10, the CPU 23 of each management device 1 interprets the wireless input detected in step S2. As a result of interpreting the wireless input from the commanding device 61 in step S10, if the wireless input is the read command, the CPU 23 of each management device 1 displays the sheet material related information and identification information of the item indicated by the read command. After reading (step S11), the sheet material related information and the identification information are associated with each other and output wirelessly by the wireless interface 64 and the antenna 65 (step S12), and the process proceeds to step S3. At this time, a known communication method capable of avoiding a collision of radio signals from each management device 1 is adopted for wireless communication between each management device 1 and the command device 61.

  In step S33 after step S32, the CPU 62 of the commanding device 61 receives the sheet material related information and the identification information output wirelessly from each management device 1 in step S12 via the antenna 65 and the wireless interface 64.

  Next, the CPU 62 of the commanding device 61 searches for the identification information received in step S33 from each management device 1 and the sheet condition related information received in step S33 associated with the identification information and input in step S31. It is determined whether or not the condition is satisfied (step S34).

  Next, the CPU 62 of the command device 61 wirelessly sends a display command to the management device 1 having the identification number associated with the sheet material related information determined to satisfy the search condition in step S34 through the wireless interface 64 and the antenna 65. Output (step S35), the process returns to step S31. This display command includes the identification number of the management apparatus 1 that is the destination.

  The display command output wirelessly from the commanding device 61 in step S35 becomes the wireless input in step S2 to the management device 1, and the CPU 23 of each management device 1 proceeds to step S10. In step S10, the CPU 23 of each management device 1 interprets the wireless input detected in step S2. As a result of interpreting the wireless input from the command device 61 in step S10, the CPU 23 of each management device 1 is the display command for itself (whether or not it is for itself is an identification number included in the display command) Can be discriminated based on whether or not it coincides with the identification number stored in the memory 24.) The roll sheet material 2 to which it is attached is input to its own display section 32 in step S31. Display indicating that the search condition is satisfied (for example, display of blinking light emission of LED in the display unit 32) is displayed for a certain time (step S13), and the process proceeds to step S3. The CPU 23 of each management device 1 interprets the wireless input from the commanding device 61 in step S10, and if the wireless input is a display command but is not directed to itself, the CPU 23 does not go through step S13. Immediately, the process proceeds to step S3.

  Therefore, according to the present embodiment, as shown in FIG. 9, in a situation where a plurality of roll-shaped sheet materials 2 to which the management device 1 is mounted are stored in a warehouse or the like, the input of the command device 61 When a desired search condition is input by the operation unit, only the display unit 32 of the management apparatus 1 mounted on the roll-shaped sheet material 2 that satisfies the search condition performs the display (for example, blinking light emission of the LED), and The display unit 32 of the management apparatus 1 mounted on the roll-shaped sheet material 2 that does not satisfy the search condition does not perform the display (for example, the LED does not emit light). Therefore, the operator can easily select the roll-shaped sheet material 2 that satisfies the desired search condition by viewing the display.

  Note that the CPU 23 of the management apparatus 1 can be connected to an external personal computer, server, or the like via USB and / or wirelessly, and in response to a command from the personal computer, server, etc. The identification number, sheet material related information, mounting start time, mounting end time, and the like stored in 24 may be output to a personal computer, a server, or the like. In this case, sheet material related information or the like can be managed by a personal computer, a server, or the like.

  According to the present embodiment, since the management apparatus 1 autonomously acquires the remaining amount of the sheet material 12 of the roll-shaped sheet material 2, the printer or the like does not have a function of acquiring the remaining amount of the sheet material 12. Even so, the remaining amount of the sheet material 12 can be acquired, and the roll-shaped sheet material 2 can be managed more appropriately.

  Moreover, according to this Embodiment, since the management apparatus 1 earns the impact history of the roll-shaped sheet material 2 autonomously, it is determined whether the roll-shaped sheet material 2 has received a large impact. The roll sheet material 2 can be managed more appropriately.

  Furthermore, according to this Embodiment, since the management apparatus 1 autonomously acquires the temperature history and humidity history of the roll-shaped sheet material 2, the roll-shaped sheet material 2 is stored at an appropriate temperature and humidity. It is possible to determine whether or not it is a thing, and to know when an inappropriate temperature and humidity are reached, so that the roll-shaped sheet material 2 can be managed more appropriately.

  Furthermore, according to the present embodiment, whether or not the main body member 21 is mounted on the roll sheet material 2 is detected by the mounting detector 22, and the main body member 21 is mounted on the roll sheet material 2. Since the impact detector 35 and the rotation amount detection unit 36 are activated only in this case, useless operations of the impact detector 35 and the rotation amount detection unit 36 can be avoided.

  In the operation of the management apparatus 1, steps S2 and S10 to S12 in FIG. 10 may be removed so that the operation in cooperation with the instruction device 61 is not performed. Even in this case, since the management device 1 can independently acquire the remaining amount, the impact history, the temperature history, and the humidity history of the sheet material 12, the roll-shaped sheet material 2 is more appropriately managed. The advantage of being able to do so is obtained.

  In the present invention, for example, in the above-described embodiment, the detectors 33 to 36 are removed from the management apparatus 1 so that the temperature history, the humidity history, and the impact history are not used as the sheet material related information. The sheet material 2 may be input from an external device such as a printer or the input operation unit 31. Even in this case, the advantage that the roll-shaped sheet material 2 satisfying a desired search condition can be easily selected is obtained.

  In the present invention, in the embodiment described above, for example, the command device 61 performs the operation shown in FIG. 12 instead of the operation shown in FIG. 11, and each management device 1 performs steps S10 to S13 in FIG. Instead of the operation shown, the operation shown in steps S51 to S53 in FIG. 13 may be performed.

  In this case, the CPU 62 of the commanding device 61 first determines whether or not a search condition is input from the input operation unit 31 (step S41). If the search condition is not input, the CPU 62 waits for the search condition to be input. When the search condition is input, the process proceeds to step S42.

  In step S42, the CPU 62 of the command device 61 causes the wireless interface 64 and the antenna 65 to wirelessly output the search condition input in step S31. At this time, the search condition is transmitted to each management device 1 so as to be received indiscriminately. After step S42, the process returns to step S41.

  The search condition wirelessly output from the commanding device 61 in step S42 becomes the wireless input of step S2 to the management device 1, and the CPU 23 of each management device 1 proceeds to step S51. In step S51, the CPU 23 of each management device 1 interprets the wireless input detected in step S2. The CPU 23 of each management device 1 interprets the wireless input from the commanding device 61 in step S51, and if the wireless input is the search condition, the detection search is stored in its own memory 24. It is determined whether or not the material related information is satisfied (step S52).

  If it is determined in step S52 that the search condition is satisfied, the CPU 23 of each management device 1 displays the search condition in which the roll sheet material 2 to which the management apparatus 1 is attached is input in step S31. A display indicating that it is satisfied (for example, a blinking light emission display of the LED in the display unit 32) is displayed for a certain period of time (step S53), and the process proceeds to step S3.

  On the other hand, if it is determined in step S52 that the search condition is not satisfied, the CPU 23 of each management device 1 immediately proceeds to step S3 without passing through step S53.

  Even in this case, as shown in FIG. 9, in a situation where a plurality of roll-shaped sheet materials 2 to which the management device 1 is mounted are stored in a warehouse or the like, the input operation unit of the command device 61 When a desired search condition is input, only the display unit 32 of the management apparatus 1 mounted on the roll sheet 2 satisfying the search condition performs the display (for example, blinking light emission of LED), and the search condition is set. The display unit 32 of the management apparatus 1 mounted on the unrolled roll-shaped sheet material 2 does not perform the display (for example, the LED does not emit light). Therefore, the operator can easily select the roll-shaped sheet material 2 that satisfies the desired search condition by viewing the display.

  Even in this case, the detectors 33 to 36 are removed from the management apparatus 1 so that the temperature history, the humidity history, and the impact history are not used as the sheet material related information. It may be input from an external device such as the input operation unit 31.

  As mentioned above, although each embodiment of this invention and its modification were demonstrated, this invention is not limited to these.

  For example, the roll-shaped sheet material to which the management device according to the present invention is attached and is a management target is not limited at all, and when manufacturing various roll-shaped sheet materials, the final product is obtained from each state in the intermediate process. You may use in order to manage the roll-shaped sheet material to.
