Description

[Technical field]

[0001] The present invention relates to a roll body determination device. [Background technology]

[0002] Corrugated cardboard sheets are manufactured by laminating cardboard base paper (front liner (flat), corrugated medium, back liner (flat)) together using a corrugating machine. The cardboard base paper is formed into roll paper that is wound into a roll. When manufacturing the cardboard sheet, the roll paper is set in a predetermined position in the corrugating machine (see, for example, Patent Document 1).

[0003] In addition, a standby position where spare roll paper is placed is provided in front of the predetermined position of the corrugating machine. The roll paper is transported by a forklift or the like from a storage area such as a warehouse to the manufacturing area where the corrugating machine is installed and is then unloaded at a predetermined storage location. The roll paper is then placed on a moving body and transported along a transport path that extends from the storage location to the predetermined position of the corrugating machine via the standby position.

[0004] Here, the spare roll paper arranged in the waiting area is transported to a specified position on the corrugating machine and used to replace the roll paper that is set in a specified position on the corrugating machine when the remaining amount of roll paper in use runs out.

[0005] [Patent Document 1] JP 2005-096311 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, if an error in the specifications of the roll paper is discovered once it has been transported to the designated location and is being set into the corrugating machine, additional steps will be required, such as removing the roll paper from the designated location, transporting a roll paper of the correct specifications from the storage area, and repositioning it in the designated location.

[0007] This causes the corrugating machine to be stopped for a longer period of time than if a roll of paper of the correct specifications was placed in the designated position, reducing the operating efficiency of the corrugating machine.

[0008] It should be noted that the above-mentioned problem is not limited to rolls of cardboard base paper used in corrugating machines, but can also occur in processing equipment that performs manufacturing and other processes using rolls of long, sheet-like materials (paper, cloth, resin, metal) wound into a roll.

[0009] The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a device for determining a roll body that can prevent a decrease in the operating efficiency of a processing device such as a corrugating machine. [Means for solving the problem]

[0010] The present invention is a roll body judgment device that includes an RFID reader that reads an identification code stored in an RFID tag attached to a roll body, which is a long sheet-like material wound into a roll and is placed at a waiting position before being placed at a predetermined position; a comparison unit that acquires correct specifications of the roll body to be placed at the predetermined position, compares the acquired correct specifications with specifications corresponding to the identification code of the roll body at the waiting position read by the RFID reader, and outputs the comparison result; and a judgment output unit that outputs a judgment as to whether the specifications of the roll body at the waiting position are correct based on the comparison result. Effect of the Invention

[0011] According to the roll body judgment device of the present invention, it is possible to prevent a decrease in the operating efficiency of a processing device such as a corrugating machine. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An embodiment of a roll body judgment device according to the present invention will be described below with reference to the drawings. Fig. 1 is a schematic diagram showing a management system for roll paper 200 that includes a management system 300 for remaining amount of roll paper 200 and a judgment device 60 for roll paper 200 according to an embodiment of the present invention. Fig. 2 is a perspective view showing the roll paper 200 that is the object of management by the roll paper 200 management system of Fig. 1, and Fig. 3 is a flowchart showing the overall operation of the management system for roll paper 200 shown in Fig. 1.

[0014] The illustrated management system for roll paper 200 (an example of a roll body) includes a barcode reader 130, an RFID label issuing machine 140, a server 150 (an example of a management device), an RFID reader 180 for inventory management, a remaining amount detection device 10, and a determination device 60.

[0015] The roll paper 200 is, for example, a long sheet-like cardboard base paper 202 (see FIG. 2) wound into a roll and used by being set in a corrugating machine for producing cardboard sheets.

[0016] 2, the roll paper 200 has a hollow cavity 201 extending in the axial direction formed in the center in the diameter direction, and cylindrical reinforcing tubes 203 are provided on both axial ends of the cavity 201. The reinforcing tubes 203 are made of, for example, a metal material, and are provided to prevent the cardboard base paper 202 around the cavity 201 from deforming when the support shaft of the corrugating machine 400 described below is inserted.

[0017] The barcode reader 130 optically reads the barcode written on the barcode label 110, refers to information (specification information) related to the specifications of the cardboard base paper 202 (such as the thickness, length, and paper type of the cardboard base paper 202) stored in the barcode reader 130 corresponding to the barcode, and outputs the referenced specification information to the outside.

[0018] In this embodiment, when a new roll of paper 200 is received (initial receipt) (YES in step 1 (S1) of the flowchart in FIG. 3), the barcode on the barcode label 110 affixed to the roll of paper 200 is read (S2 in FIG. 3), and the specification information corresponding to the barcode is output to the RFID label issuing machine 140.

[0019] The specification information of the cardboard base paper 202 corresponding to the barcode does not have to be stored in the barcode reader 130 itself, but may be obtained from an external source such as the server 150.

[0020] The RFID label issuing machine 140 issues an RFID label 120 (RFID tag) that has an IC chip that stores an identification code (ID) that corresponds to the barcode input from the barcode reader 130 (S3 in FIG. 3). The RFID label 120 issued by the RFID label issuing machine 140 is affixed to the stored roll paper 200 either manually by a worker or automatically by a robot. The roll paper 200 with the RFID label 120 affixed to it is transported to a designated storage area and stored.

[0021] Figures 4 to 6 are diagrams showing the positions at which the RFID label 120 is attached to the roll paper 200. Figure 4 is a cross-sectional view of the essential parts showing the state where it is attached to a non-metallic part facing the cavity 201 of the roll paper 200. Figure 5 is a cross-sectional view of the essential parts showing the state where it is attached to the reinforcing tube 203 facing the cavity 201 of the roll paper 200. Figure 6 is a cross-sectional view of the essential parts showing the state where it is attached across the reinforcing tube 203 and a non-metallic part facing the cavity 201 of the roll paper 200.

[0022] Here, the RFID label 120 may be attached, for example, to a portion of the cavity 201 in the roll paper 200 that does not contact the reinforcing tube 203, i.e., to the non-metallic portion of the roll paper 200, as shown in FIG. 4, or may be attached to the reinforcing tube 203 in the cavity 201 in the roll paper 200, as shown in FIG. 5, or may be attached so as to straddle the reinforcing tube 203 and the non-metallic portion of the cavity 201 in the roll paper 200, as shown in FIG. 6.

[0023] It is generally desirable to place RFID label 120 away from metal parts, so the arrangement shown in Figure 4 is preferable, but there are also RFID labels that exhibit sufficient reception sensitivity even when in contact with metal parts. When such an RFID label 120 is used, the arrangement shown in Figures 5 and 6 may be used, in which case reinforcing tube 203, which is the metal part, can function as an antenna.

[0024] The RFID label issuing machine 140 outputs to the server 150 the identification code stored in the issued RFID label 120 (its IC chip) and the specification information of the cardboard base paper 202 obtained as a barcode or from an external source.

[0025] Server 150, which is an example of a management device, includes database 160 and update unit 170. Database 160 stores an identification code (ID) input from RFID label issuing machine 140 and various information such as specification information and inventory information for cardboard base paper 202, in association with each other, and update unit 170 registers the identification code and specification information of the received roll paper 200 in database 160, in association with each other (S4 in FIG. 3).

[0026] Fig. 7 is a diagram showing a specific example of database 160. As shown in Fig. 7, in the specific example of database 160, paper type, first stocking date, last use date, remaining amount (remaining length), and storage area, which are examples of inventory information, are associated with identification codes. Note that the specific contents of database 160 are not limited to the example shown in Fig. 7.

[0027] The update unit 170 updates the information by rewriting the length in the specification information of the cardboard base paper 202 stored in the database 160 to the remaining amount of the cardboard base paper 202 in the roll paper 200 output from the remaining amount detection device 10 described below, and by rewriting the inventory information.

[0028] The inventory information in database 160 is updated when an RFID reader 180 for inventory management (described below) reads the RFID label 120 of roll paper 200 stored in the storage area and queries server 150 (S5 in FIG. 3), and information on the storage area for roll paper 200 being stocked for the first time is registered by this update.

[0029] The inventory control RFID reader 180 reads the identification code from the RFID label 120 attached to each of the numerous rolls of paper 200 (e.g., paper rolls 210, 220, ..., 280) that have been received and stored in a storage area such as a warehouse, and compares the codes with database 160 in server 150 to manage inventory information such as the presence or absence of rolls of paper 200 (registering and updating the storage area in the database).

[0030] Since the RFID reader 180 can read information such as the identification code stored in the RFID label 120 without coming into contact with the RFID label 120, there is no need to approach each individual roll of paper 200 stored in the warehouse, as is the case with a barcode reader.

[0031] That is, it is possible to read the identification codes of multiple RFID labels 120 present in a certain range of space almost simultaneously at one time. The certain range is the distance range in which communication is possible between the RFID reader 180 and the RFID labels 120, and within the certain range, the RFID reader 180 can read information such as the identification codes stored in the RFID labels 120 in a non-contact manner.

[0032] The certain range will vary depending on the specifications of the RFID reader 180 and the RFID label 120 and the condition of the space (whether it is a space separated by a wall or an open space without a wall, as well as the density of the arrangement of the paper rolls 200 to which the RFID labels 120 are attached.) Therefore, inventory management using the RFID label 120 can significantly reduce the effort required for inventory management of the paper rolls 200 in a warehouse.

[0033] (Remaining amount detection device, remaining amount management system) FIG. 8 is a block diagram showing the configuration of the remaining amount detection device 10, and FIG. 9 is a schematic diagram showing a portion of a corrugating machine 400 (an example of a processing device) that produces cardboard sheets using roll paper 200 set in predetermined positions 410, 420, and 430.

[0034] As shown in Fig. 8, the remaining amount detection device 10 includes an RFID reader 20, a sensor 30, and an output unit 40. For example, as shown in Fig. 9, the remaining amount detection device 10 is disposed near predetermined positions 410, 420, 430 where the roll paper 200 is set in a corrugating machine 400 that produces cardboard sheets by unwinding base cardboard paper 202 from the roll paper 200. The remaining amount detection device 10 is configured separately from the corrugating machine 400.

[0035] 11 , which will be described later, the roll paper 200 is placed on a plate-shaped transport body 470 that moves along a transport path 450 formed on the floor that extends via a standby position 450 to the predetermined position 410, and the transport body 470 with the roll paper 200 placed on it moves along the transport path 450 to the predetermined position 410, setting the roll paper 200 at the predetermined position 410. The same process is used to set the roll paper 200 at the other predetermined positions 420, 430.

[0036] The range in which the RFID label 120 of each roll of paper 200 placed in each of the predetermined positions 410, 420, 430 is positioned will vary depending on the specifications of the RFID reader 20 and the RFID label 120 and the spatial conditions, as in the case of the RFID reader 180 described above, but is the range in which the RFID label 120 of each roll of paper 200 placed in each of the predetermined positions 410, 420, 430 can be read.

[0037] In other words, the RFID reader 20 placed near the specified position 410 is configured so that the direction of the transmitted radio waves and the strength of the electric field are adjusted in advance, so that it can communicate with the RFID label 120 of the roll paper 200 placed at the specified position 410 and read information such as the stored identification code.

[0038] With a similar setting, an RFID reader 20 placed near a designated position 420 can read information such as the identification code of the RFID label 120 of the roll paper 200 placed at the designated position 420, and an RFID reader 20 placed near a designated position 430 can read information such as the identification code of the RFID label 120 of the roll paper 200 placed at the designated position 430.

[0039] The sensor 30 detects, in a non-contact manner, the remaining amount (remaining length) of the cardboard base paper 202 of the roll paper 200 placed at a predetermined position 410. The sensor 30 detects the diameter or radius of the roll paper 200, for example, by irradiating the roll paper 200 with laser light. The sensor 30 also includes a calculation unit that calculates the remaining amount of the cardboard base paper 202 based on the detected diameter or radius.

[0040] Specifically, the calculation unit of the sensor 30 calculates the remaining amount based on the detected diameter or radius and the thickness of the base paper 202. The thickness of the base paper 202 is regulated by the specifications of the roll paper 200, so the calculation unit may store it in advance, or the output unit 40 of the remaining amount detection device 10 may communicate with the server 150 to obtain specification information for the roll paper 200 stored in a database 160 of the server 150.

[0041] The sensor 30 may be any sensor that detects the remaining amount of the cardboard base paper 202 of the roll paper 200, and is not limited to a sensor that uses laser light to detect the diameter or radius of the roll paper 200. Therefore, the sensor may be one that detects the diameter or radius of the roll paper 200 using a method other than laser light, or one that detects a physical quantity other than the diameter or radius of the roll paper 200.

[0042] An example of a physical quantity to be detected that is different from the diameter or radius of the roll paper 200 is the number of rotations per hour (rotational speed) of the cardboard base paper 202 from the roll paper 200 while the corrugating machine 400 is in operation. The corrugating machine 400 produces cardboard sheets at a constant speed, so the speed at which the roll paper 200 is unwound and the cardboard base paper 202 is paid out is constant.

[0043] The rotation speed of the roll paper 200, which rotates as the cardboard base paper 202 is paid out, is determined by the diameter or radius of the roll paper 200. In other words, the smaller the diameter or radius of the roll paper 200, the faster the rotation speed of the roll paper 200. Therefore, by detecting the rotation speed of the roll paper 200, the sensor 30 can detect the remaining amount of cardboard base paper 202 on the roll paper 200 in relation to the constant speed at which cardboard sheets are manufactured (the payout speed of the cardboard base paper).

[0044] In addition, since the constant speed at which the cardboard sheets are manufactured (the cardboard paper feed speed) can be obtained in advance when the corrugating machine is operated, the calculation unit of the sensor 30 may store this in advance.

[0045] The output unit 40 outputs the identification code of the roll paper 200 read by the RFID reader 20 and the remaining amount of the cardboard base paper 202 detected by the sensor 30 as information in association with each other.

[0046] The information correlating the identification code of the roll paper 200 output from the output unit 40 with the remaining amount of cardboard base paper 202 is input to the server 150 (S7 in FIG. 3). The update unit 170 of the server 150 uses the associated information to identify the roll paper 200 that corresponds to the input identification code of the roll paper 200 from the information stored in the database 160, and rewrites (updates) the remaining amount of the specification information that corresponds to the identification code of the roll paper 200 with the input remaining amount of cardboard base paper 202 (S8 in FIG. 3).

[0047] As explained in detail above, the device 10 for detecting remaining amount of rolled paper 200 is configured as follows: That is, the device for detecting remaining amount of rolled body (rolled paper 200) (device for detecting remaining amount of rolled body 10) includes an RFID reader (RFID reader 20) that contactlessly reads an identification code from an RFID tag (RFID label 120) that stores an identification code identifying the rolled body and that is affixed to the rolled body (rolled paper 200) made of a long sheet-like material (corrugated cardboard base paper 202) wound into a roll, a sensor (sensor 30) that contactlessly detects the remaining amount or amount of material used, and an output unit (output unit 40) that associates the identification code read by the RFID reader with the remaining amount of material detected by the sensor, or associates the identification code read by the RFID reader with the amount used detected by the sensor, and outputs the association to a server (server 150) in which the remaining amount of material for each roll is stored. The remaining amount detection device 10 is disposed in the vicinity of a predetermined position (predetermined positions 410, 420, 430) where the roll body is disposed in a processing device (corrugating machine 400) that unwinds the material from the roll body and uses it.

[0048] With this configuration, the remaining amount detection device 10 can independently obtain the remaining amount of the cardboard base paper 202 wound around the roll paper 200, so there is no need to obtain the remaining amount from the corrugating machine 400 by, for example, modifying the corrugating machine 400.

[0049] Therefore, the remaining amount detection device 10 can automatically obtain and manage the remaining amount of cardboard base paper in the roll paper 200 without relying on the corrugating machine 400.

[0050] In addition, the sensor 30 in the remaining amount detection device 10 detects the remaining amount without contacting the rolled paper 200, so there is no contact resistance with the rolled paper 200 as with sensors that detect the remaining amount by contacting the rolled paper 200, and there is no effect on the operation of the corrugating machine 400.

[0051] The sensor 30 may be one that comes into contact with the roll paper 200. That is, if the sensor 30 is, for example, a driven roller type that comes into contact with the cardboard paper 202, the payout length of the cardboard paper 202 (=circumference × number of rotations; amount used) can be detected from the circumference and number of rotations of the driven roller.

[0052] The remaining amount detection device 10 and the server 150 storing the database 160 constitute a remaining amount management system 300 (see FIG. 8) for the roll paper 200. That is, the roll remaining amount management system (remaining amount management system 300) includes a server (server 150) that stores a database (database 160) in which an identification code that identifies the roll body (roll paper 200) and is stored in an RFID tag (RFID label 120) attached to the roll body corresponds to the remaining amount of the material (corrugated board base paper 202) in the roll body, and a remaining amount detection device (remaining amount detection device 10), and the server includes an update unit (update unit 170) that rewrites the remaining amount of the material associated with the roll body of the identification code in the database to the remaining amount input from the remaining amount detection device, or rewrites it to the remaining amount obtained by subtracting the usage amount output from the remaining amount detection device from the remaining amount of the material stored in the database.

[0053] With this configuration, the remaining amount management system 300 can independently obtain the remaining amount of the cardboard base paper 202 wound around the roll paper 200, so there is no need to obtain the remaining amount from the corrugating machine 400 by, for example, modifying the corrugating machine 400.

[0054] Therefore, the remaining amount management system 300 can automatically obtain and manage the remaining amount of cardboard base paper in the roll paper 200 without relying on the corrugating machine 400, thereby reducing the effort and cost of managing roll paper inventory.

[0055] Note that the above explanation is of the remaining amount detection device 10 when the roll paper 200 is set at the predetermined position 410 of the corrugating machine 400, but other remaining amount detection devices 10 for roll paper 200 set at other predetermined positions 420, 430 have the same configuration and perform the same function.

[0056] Further, the remaining amount detection device 10 is disposed near the predetermined position 410 of the corrugating machine 400, but is not limited to being disposed near the predetermined position 410 of the corrugating machine 400.

[0057] In other words, the roll body remaining amount detection device and the remaining amount detection device of the remaining amount management system may be configured such that the sensor 30 and the RFID reader 20 are arranged near a predetermined position 410 or the like of the corrugating machine 400, and the output unit 40 is arranged at a position away from the predetermined position 410 or the like, and the sensor 30 and the RFID reader 20 are connected to the output unit 40 wirelessly.

[0058] Furthermore, according to the remaining amount management system 300 having the remaining amount detection device 10 and the server 150 storing the database 160, the remaining amount of the cardboard base paper 202 wound around the roll paper 200 can be obtained independently, so there is no need to obtain the amount from the corrugating machine 400 by, for example, modifying the corrugating machine 400.

[0059] The sensor 30 in the remaining amount detection device 10 detects the remaining amount of the base paper 202, but the physical quantity detected by the sensor 30 is not limited to the radius or diameter of the roll paper 200 or the rotational speed of the roll paper 200. In other words, the sensor 30 may detect the length (amount used) of the base paper 202 from the roll paper 200 used by the corrugating machine 400.

[0060] In this case, the sensor 30 only needs to detect the length of the cardboard paper 202 being fed by the corrugating machine 400. The remaining amount (initial value) of the cardboard paper 202 before the roll paper 200 is set in the predetermined position 410 of the corrugating machine 400 is stored in the database 160.

[0061] Therefore, when the sensor 30 detects the amount of cardboard paper 202 used by the corrugating machine 400, the sensor 30 can obtain the remaining amount of cardboard paper 202 by subtracting the usage fee from the remaining amount (initial value) obtained from the database 160.

[0062] If the corrugating machine 400 is equipped with a monitor that displays the remaining amount or amount of cardboard paper 202 used on the roll paper 200 currently set in the specified position 410, a camera device that photographs the remaining amount or amount used displayed on the monitor and acquires the image of the remaining amount or amount used as numerical data by image recognition processing can also be used as the sensor 30. In other words, the sensor 30 may be any device that acquires the remaining amount of cardboard base paper 202 on the roll paper 200 set in the specified position 410, 420, 430.

[0063] (judgment device) Figure 10 is a block diagram showing the configuration of a roll paper determination device 60 in one embodiment of the present invention, and Figure 11 is a schematic diagram showing the determination device 60 positioned near a spare roll paper 220 (200) that is placed in a standby position 411 on the same transport path 450 as the roll paper 210 (200) set in a predetermined position 410 of the corrugating machine.

[0064] Determination device 60 is one embodiment of a roll determination device according to the present invention, and as shown in Fig. 10, includes an RFID reader 20, a collation unit 70, and a determination output unit 80. As shown in Fig. 11, for example, determination device 60 is placed near spare roll paper 220 that is placed in standby position 411 on the same transport path 450 as roll paper 210 that is set in a predetermined position 410 of the corrugating machine and is to be used.

[0065] The roll paper 220 placed on the transport body 460 and arranged at the standby position 411 is a spare roll paper to be used when the remaining amount of cardboard base paper 202 in the roll paper 210 currently being used by the corrugating machine 400 runs out. When the remaining amount of the roll paper 210 set at the predetermined position 410 runs out, the roll paper 220 set at the standby position 411 advances to the predetermined position 410 along the transport path 450 while still placed on the transport body 460, and is set at the predetermined position 410 in place of the roll paper 210. The roll paper 220 placed at the predetermined position 410 is then used by the corrugating machine 400 to manufacture cardboard sheets.

[0066] The RFID reader 20 communicates only with the RFID label 120 of the roll paper 220 placed in the standby position 411 and reads information such as the stored identification code, but does not communicate with the RFID label 120 of the roll paper 210 placed in the specified position 410 and does not read information such as the identification code stored in the RFID label 120 of the roll paper 210.

[0067] The collation unit 70 communicates with the server 150 and obtains the correct specifications of the roll paper 200 to be placed in the predetermined position 410 (such as the type of paper for the cardboard base paper 202) from the production plan held by the server 150.

[0068] The production plan held by the server 150 is a production plan formulated by a production management system that manages the production of cardboard sheets by the corrugating machine 400. The production plan includes the correct specifications of the roll paper 200 required for the production plan of the cardboard sheets by the corrugating machine 400.

[0069] The collation unit 70 checks the database 160 of the server 150 for the identification code stored in the RFID label 120 of the paper roll 220 in the standby position 411 that was read by the RFID reader 20. The collation unit 70 then compares the specification information corresponding to the identification code of the paper roll 220 obtained from the database 160 with the correct specifications obtained from the production plan held by the server 150, and outputs the collation result to the judgment output unit 80 as to whether or not the specifications of the paper roll 220 match the correct specifications that should be set in the specified position 410 of the corrugating machine 400.

[0070] The judgment output unit 80 is, for example, a display device, and displays (outputs) a judgment based on the comparison result input from the comparison unit 70 as to whether the specifications of the roll paper 220 set in the waiting position 411 match the correct specifications to be set in the specified position 410 of the corrugating machine 400.

[0071] Specifically, when a comparison result is received indicating that the specifications of the roll paper 220 match the correct specifications, the judgment output unit 80 displays a "correct" judgment. On the other hand, when a comparison result is received indicating that the specifications of the roll paper 220 do not match the correct specifications, the judgment output unit 80 displays a "incorrect" judgment.

[0072] When the judgment output unit 80 displays the judgment "Wrong," it makes the judgment "Wrong" stand out in order to inform surrounding workers that the roll paper 220 set in the standby position 411 is of the wrong specifications. Specifically, the judgment output unit 80 displays the judgment "Wrong" in a color that is easily noticeable to workers, or by flashing it.

[0073] Furthermore, the determination output section 80 may issue an alarm sound to notify the operator, instead of or in addition to making the display stand out.

[0074] When the judgment of the roll paper 220 waiting at the standby position 450 is "incorrect," the judgment output unit 80 outputs an instruction signal to the transport body 460 so as not to automatically move the transport body 460 from the standby position 450 to the specified position 410, and maintains the roll paper 220 stopped at the standby position 450.

[0075] On the other hand, when the judgment of the roll paper 220 is "positive," the judgment output unit 80 outputs an instruction signal to the transport body 460 to allow the spare roll paper 220 in the standby position 411 to be automatically transported to the specified position 410 when the roll paper 210 at the specified position 410 runs out.

[0076] As described above in detail, the roll paper judgment device 60 of this embodiment is configured as follows: That is, the roll body (roll paper) judgment device 60 of this embodiment includes an RFID reader (RFID reader 20) that reads an identification code stored in an RFID tag (RFID label 120) of a roll body (roll paper 220) made of a long sheet-like material (corrugated cardboard base paper 202) wound into a roll and that is placed in a standby position (standby position 411) before being placed in a predetermined position (predetermined position 410), a collation unit (collation unit 70) that acquires correct specifications of the roll body to be placed in the predetermined position, compares the acquired correct specifications with specifications corresponding to the identification code of the roll body at the standby position read by the RFID reader, and outputs the comparison result, and a judgment output unit (judgment output unit 80) that outputs a judgment as to whether the specifications of the roll body at the standby position are correct or not according to the comparison result.

[0077] With this configuration, the roll paper judgment device 60 of this embodiment can automatically judge whether the roll paper 220 placed in the standby position 411 as a spare roll paper for the roll paper 210 placed in the specified position 410 and used in the corrugating machine 400 is of the correct specifications for a spare roll paper, before the roll paper 220 is actually set in the specified position 410.

[0078] If the comparison result indicates that the roll paper 220 is of incorrect specifications, the roll paper 220 stopped at the standby position 411 can be removed from the standby position 411 by manual operation or the like, and the roll paper 200 of the correct specifications can be repositioned at the standby position 411.

[0079] This makes it possible to improve the operating efficiency of the corrugating machine 400 compared to a case in which the roll paper 220 of the incorrect specifications is actually placed in the predetermined position 410 and the incorrect specifications are discovered at that time.

[0080] That is, if roll paper 220 of incorrect specifications is placed in predetermined position 410 and the incorrect specifications are discovered at that timing, extra steps are required to move roll paper 220 away from predetermined position 410 and replace roll paper of the correct specifications in predetermined position 410. Therefore, compared to when such extra steps do not occur, the corrugating machine 400 is stopped for longer periods of time, reducing the operating efficiency of the corrugating machine 400.

[0081] However, the determination device 60 of this embodiment can determine whether the roll paper 220 with incorrect specifications is in the waiting position 411 before it is placed at the specified position 410, so that the roll paper 210 placed at the specified position 410 is used and the roll paper 220 with incorrect specifications can be replaced with a roll paper with the correct specifications while the corrugating machine 400 is operating, without extending the time the corrugating machine 400 is stopped and without reducing the operating efficiency of the corrugating machine 400.

[0082] Furthermore, since the determination device 60 does not obtain information on the specifications of the cardboard base paper 202 used in production by the corrugating machine 400 from the corrugating machine 400, there is no need to modify the corrugating machine 400.

[0083] In other words, the determination device 60 of this embodiment can automatically determine the specifications of the cardboard base paper 202 in the roll paper 220 placed in the standby position 411 without relying on the corrugating machine 400.

[0084] In the judgment device 60 of this embodiment, the judgment output unit 80 itself outputs the display and sound of the judgment, but in the judgment device of the present invention, the judgment output unit may output the judgment to an external monitor or the like connected wirelessly or the like, and cause the monitor to display the judgment or generate an alarm sound.

[0085] FIG. 12 shows an example of a screen display on the monitor 90 that displays a list of the “correct” or “incorrect” judgments for the spare roll paper 220 that is connected wirelessly or via wired connection to each judgment device 60 and placed in all waiting positions 411, 421, 431.

[0086] For example, as shown in FIG. 9, in a corrugating machine 400 in which two rolls of paper 200, 200 in use are placed at a designated position 410, two rolls of paper 200, 200 in use are placed at a designated position 420, and two rolls of paper 200, 200 in use are placed at a designated position 430, two spare rolls of paper 220 are placed at standby positions 411, 421, 431 corresponding to the rolls of paper 200 in use at each of the designated positions 410, 420, 430, respectively.

[0087] Thus, a determination device 60 may be provided corresponding to each of the spare rolls of paper, and the determination output section 80 of each determination device 60 may display a list of "correct" or "incorrect" determinations for all of these spare rolls of paper 220 (six in total) placed in the waiting positions 411, 421, 431 on an external monitor 90 (display device) connected wirelessly or by wire to each determination device 60, as shown in Fig. 12. The external monitor 90 may be connected to each determination device 60 via a server 150. Note that the external monitor 90 is separate from the determination device 60, but may be part of the components that make up the determination device 60.

[0088] In this way, by outputting the judgments of multiple spare roll paper 220 in a list on one monitor 90, the judgments of multiple spare roll paper 220 can be confirmed all at once on the single monitor 90, which reduces the effort required for confirmation compared to going around and checking the judgments of each judgment device 60.

[0089] In the above description, the determination device 60 is configured separately from the remaining amount detection device 10, but the determination device 60 may be incorporated into the remaining amount detection device 10. In this case, the RFID reader 20 of the determination device 60 and the RFID reader 20 of the remaining amount detection device 10 can be shared by a single RFID reader 20.

[0090] The roll paper remaining amount detection device 10, remaining amount management system 300, and determination device 60 of this embodiment use roll paper 200, in which a long, sheet-like cardboard base paper 202 is wound into a roll, as the roll body, and a corrugating machine 400, which unwinds the cardboard base paper 202 from the roll paper 200 and uses it, as the processing device.

[0091] However, the roll body remaining amount detection device, remaining amount management system and determination device of the present invention can be applied not only to cardboard base paper, but also to processing equipment that performs manufacturing and other processes using a roll body in which a long, sheet-like material (paper, cloth, resin, metal) is wound into a roll, not limited to corrugating machines.
