Description

The present invention relates to a roll body determination device.

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 rolled paper. When manufacturing cardboard sheets, the rolled paper is set in a specified position in the corrugating machine (see, for example, Patent Document 1).

In addition, a standby position where spare roll paper is placed is provided just before the designated 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 designated 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 designated position of the corrugating machine, via the standby position.

The spare roll paper placed in the waiting area is transported to the specified position of the corrugating machine and used to replace the roll paper that is currently being used and is set in a specified position on the corrugating machine when the remaining amount of the roll paper runs out.

JP 2005-096311 A

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, the roll paper must be removed from the designated location, and a roll paper with the correct specifications must be transported from the storage area and placed back in the designated location, resulting in unnecessary steps.

This causes the corrugating machine to be stopped for longer periods of time than if a roll of paper with the correct specifications were placed in the designated position, reducing the operating efficiency of the corrugating machine.

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 uses rolls of long, sheet-like materials (paper, cloth, resin, metal) wound into a roll to carry out manufacturing and other processes.

The present invention has been made in consideration of the above circumstances, and aims to provide a roll body determination device that can prevent a decrease in the operating efficiency of processing equipment such as a corrugating machine.

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 in a standby position before being placed in a predetermined position; a comparison unit that acquires the correct specifications of the roll body to be placed in the predetermined position, compares the acquired correct specifications with the specifications corresponding to the identification code of the roll body in the standby 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 in the standby position are correct or not, based on the comparison result.

The roll body judgment device according to the present invention can prevent a decrease in the operating efficiency of processing equipment such as corrugating machines.

FIG.

The following describes an embodiment of the roll body determination device according to the present invention with reference to the drawings. Fig. 1 is a schematic diagram showing a roll paper 200 management system including a roll paper 200 remaining amount management system 300 and a roll paper 200 determination device 60 according to an embodiment of the present invention. Fig. 2 is a perspective view showing the roll paper 200 that is the subject of management by the roll paper 200 management system of Fig. 1, and Fig. 3 is a flowchart showing the overall operation of the roll paper 200 management system shown in Fig. 1.

The management system for the illustrated 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.

As an example, the roll paper 200 is a long sheet of cardboard base paper 202 (see Figure 2) wound into a roll and used by setting it in a corrugating machine to manufacture cardboard sheets.

As shown in FIG. 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 at both axial ends of the cavity 201. The reinforcing tubes 203 are formed, for example, from a metal material, and are provided to prevent deformation of the cardboard base paper 202 around the cavity 201 when the support shaft of the corrugating machine 400 described below is inserted.

The barcode reader 130 optically reads the barcode printed on the barcode label 110, references information (specification information) related to the specifications of the cardboard base paper 202 (such as the thickness, length, and type of paper of the cardboard base paper 202) stored in the barcode reader 130 in correspondence with the barcode, and outputs the referenced specification information to the outside.

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 attached 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.

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.

The RFID label issuing machine 140 issues an RFID label 120 (RFID tag) having an IC chip that stores an identification code (ID) corresponding 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 an operator 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.

Figures 4 to 6 show the position of attachment of the RFID label 120 to the roll paper 200. Figure 4 is a cross-sectional view of the essential parts showing the RFID label 120 attached to the 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 RFID label 120 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 RFID label 120 attached across the reinforcing tube 203 and the non-metallic part facing the cavity 201 of the roll paper 200.

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

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

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.

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

Figure 7 is a diagram showing an example of a specific database 160. As shown in Figure 7, in a 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 Figure 7.

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 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.

The inventory information in the database 160 is updated (S6 in FIG. 3) when the RFID reader 180 for inventory management (described below) reads the RFID label 120 of the roll paper 200 stored in the storage area and queries the server 150 (S5 in FIG. 3), and the information on the storage area for the roll paper 200 that is being stocked for the first time is registered by the update at this time.

The inventory management RFID reader 180 reads the identification code from the RFID label 120 attached to each of the many rolls of paper 200 (e.g., rolls 210, 220, ... 280) that have been received and stored in a storage area such as a warehouse, and compares it with the database 160 of the 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).

The RFID reader 180 can read information such as the identification code stored on the RFID label 120 without coming into contact with the RFID label 120, so unlike a barcode reader, it does not need to be in close proximity to each individual roll of paper 200 stored in the warehouse.

In other words, it is possible to read the identification codes of multiple RFID labels 120 present in a certain range of space almost simultaneously at once. 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 without contact.

The certain range varies 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, and the density of the arrangement of the rolls of paper 200 to which the RFID labels 120 are attached, etc.). Therefore, inventory management using the RFID label 120 can significantly reduce the effort required for inventory management of the rolls of paper 200 in a warehouse.

(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.

As shown in FIG. 8, the remaining amount detection device 10 includes an RFID reader 20, a sensor 30, and an output unit 40. As shown in FIG. 9, for example, 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 cardboard base paper 202 from the roll paper 200. The remaining amount detection device 10 is configured separately from the corrugating machine 400.

As shown in FIG. 11, which will be described later, the roll paper 200 is placed at the predetermined position 410 by placing the roll paper 200 on a plate-shaped transport body 470 that proceeds along a transport path 450 formed on the floor that extends to the predetermined position 410 via a standby position 450, and the transport body 470 with the roll paper 200 placed on it proceeds along the transport path 450 to the predetermined position 410, thereby 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.

The range in which the RFID reader 20 is positioned near the predetermined positions 410, 420, and 430 varies 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 positioned at each predetermined position 410, 420, and 430 can be read.

In other words, the RFID reader 20 placed near the specified position 410 is set 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.

By using a similar setting, an RFID reader 20 placed near a predetermined position 420 can read information such as the identification code of the RFID label 120 of the roll paper 200 placed at the predetermined position 420, and an RFID reader 20 placed near a predetermined position 430 can read information such as the identification code of the RFID label 120 of the roll paper 200 placed at the predetermined position 430.

The sensor 30 detects the remaining amount (remaining length) of the cardboard base paper 202 of the roll paper 200 placed at the specified position 410 in a non-contact manner. 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.

Specifically, the calculation unit of the sensor 30 calculates the remaining amount based on the detected diameter or radius and the thickness of the cardboard base paper 202. Since the thickness of the cardboard base paper 202 is determined by the specifications of the roll paper 200, 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 the specification information of the roll paper 200 stored in the database 160 of the server 150.

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 detects the diameter or radius of the roll paper 200 using laser light. 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.

An example of a physical quantity that is 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 unwound is constant.

The rotation speed of the roll paper 200, which rotates as the cardboard base paper 202 is unwound, 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 unwound speed of the cardboard base paper).

The constant speed at which cardboard sheets are manufactured (the cardboard paper feed speed) can be obtained in advance when the corrugating machine is operated, so the calculation unit of the sensor 30 can store this in advance.

The output unit 40 outputs information that correlates the identification code of the roll paper 200 read by the RFID reader 20 with the remaining amount of cardboard base paper 202 detected by the sensor 30.

The information output from the output unit 40, which associates the identification code of the roll paper 200 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 identification code of the roll paper 200 that was input 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 to the remaining amount of the input cardboard base paper 202; S8 in FIG. 3.

As described above in detail, the device 10 for detecting the remaining amount of rolled paper 200 is configured as follows. That is, the device for detecting the remaining amount of rolled paper (rolled paper 200) (device for detecting the remaining amount of rolled paper 200) 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 that identifies the rolled paper 200, which is attached to the 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 remaining amount of material for each rolled paper to a server (server 150) in which the remaining amount of material is stored. The remaining amount detection device 10 is placed near a predetermined position (predetermined positions 410, 420, 430) where the roll body is placed in a processing device (corrugating machine 400) that unwinds the material from the roll body and uses it.

With this configuration, the remaining amount detection device 10 can independently obtain the remaining amount of the corrugated 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 modifying the corrugating machine 400, etc.

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.

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

The sensor 30 may be in contact with the roll paper 200. That is, if the sensor 30 is, for example, a driven roller type that contacts the cardboard paper 202, the payout length of the cardboard paper 202 (= circumference x number of rotations; amount used) can be detected based on the circumference and number of rotations of the driven roller.

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 body 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 base paper 202) in the roll body, and a remaining amount detection device (remaining amount detection device 10). 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 the remaining amount of the material stored in the database 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.

With this configuration, the remaining amount management system 300 can independently obtain the remaining amount of the corrugated 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 modifying the corrugating machine 400, etc.

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 the inventory of roll paper.

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

The remaining amount detection device 10 is arranged near a predetermined position 410 of the corrugating machine 400, but is not limited to being arranged near a predetermined position 410 of the corrugating machine 400.

In other words, the roll 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 disposed near a predetermined position 410 or the like of the corrugating machine 400, the output unit 40 is disposed at a position away from the predetermined position 410 or the like, and the sensor 30 and the RFID reader 20 are wirelessly connected to the output unit 40.

In addition, the remaining amount management system 300, which has a remaining amount detection device 10 and a server 150 that stores a database 160, can independently obtain the remaining amount of the corrugated base paper 202 wound around the roll paper 200, so there is no need to obtain the amount from the corrugating machine 400 by modifying the corrugating machine 400, etc.

The sensor 30 in the remaining amount detection device 10 detects the remaining amount of the base cardboard 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 rotation speed of the roll paper 200 described above. In other words, the sensor 30 may detect the length (amount of use) of the base cardboard paper 202 from the roll paper 200 used by the corrugating machine 400.

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

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.

When 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, the sensor 30 can be 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. In other words, the sensor 30 can 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.

(Determination 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.

The determination device 60 is one embodiment of the roll body 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. For example, as shown in FIG. 11, the determination device 60 is placed near a spare roll paper 220 that is placed in a standby position 411 on the same transport path 450 as the roll paper 210 that is set in a predetermined position 410 of the corrugating machine and used.

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 specified position 410 runs out, the roll paper 220 set at the standby position 411 advances to the specified position 410 along the transport path 450 while still placed on the transport body 460, and is set at the specified position 410 in place of the roll paper 210. The roll paper 220 placed at the specified position 410 is then used by the corrugating machine 400 to manufacture cardboard sheets.

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.

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

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 using the corrugating machine 400. The production plan includes the correct specifications of the roll paper 200 required to correspond to the production plan of manufacturing cardboard sheets using the corrugating machine 400.

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

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

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

When the judgment output unit 80 displays the judgment "incorrect," it makes the judgment "incorrect" more noticeable to inform surrounding workers that the roll paper 220 set in the standby position 411 is of incorrect specifications. Specifically, the judgment output unit 80 displays the judgment "incorrect" in a color that is easily noticeable to workers, or makes it blink.

The judgment output unit 80 may also generate an alarm sound to alert the operator, instead of or in addition to highlighting the display.

When the determination of the roll paper 220 waiting at the standby position 450 is "incorrect," the determination 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.

On the other hand, when the roll paper 220 is judged to be "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 remaining amount of roll paper 210 in the specified position 410 runs out.

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) in which a long sheet-like material (corrugated cardboard base paper 202) is 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 the correct specifications of the roll body to be placed in the predetermined position, compares the acquired correct specifications with the specifications corresponding to the identification code of the roll body at the standby position read by the RFID reader, and outputs the collation 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 collation result.

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 by 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.

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.

This improves the operating efficiency of the corrugating machine 400 compared to a case in which the roll paper 220 with the incorrect specifications is actually placed in the specified position 410 and the incorrect specifications are noticed at that time.

In other words, if roll paper 220 with incorrect specifications is placed in the specified position 410 and the incorrect specifications are noticed at that timing, extra steps are required to move the roll paper 220 away from the specified position 410 and reposition roll paper with the correct specifications at the specified position 410. As a result, the corrugating machine 400 is stopped for longer periods of time than if such extra steps were not required, reducing the operating efficiency of the corrugating machine 400.

However, the determination device 60 of this embodiment can determine whether the roll paper 220 with the incorrect specifications is in the standby position 411 before it is placed in the specified position 410. Therefore, the roll paper 210 placed in the specified position 410 can be used and the roll paper 220 with the incorrect specifications can be replaced with a roll paper with the correct specifications while the corrugating machine 400 is operating. This does not lengthen the time the corrugating machine 400 is stopped, and does not reduce the operating efficiency of the corrugating machine 400.

In addition, since the determination device 60 does not obtain information regarding the specifications of the corrugated board 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.

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.

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 according to the present invention, the judgment output unit may output the judgment to an external monitor connected wirelessly or the like, and cause the monitor to display the judgment or generate an alarm sound.

Figure 12 shows an example of a screen display on the monitor 90 that displays a list of "correct" or "incorrect" judgments for the spare roll paper 220 placed in all standby positions 411, 421, and 431 that are connected wirelessly or by wire to each judgment device 60.

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 predetermined position 410, two rolls of paper 200, 200 in use are placed at a predetermined position 420, and two rolls of paper 200, 200 in use are placed at a predetermined position 430, two spare rolls of paper 220 are placed at standby positions 411, 421, and 431 corresponding to the rolls of paper 200 in use at each of the predetermined positions 410, 420, and 430, respectively.

Therefore, a determination device 60 corresponding to each of the spare rolls of paper may be arranged, and the determination output unit 80 of each determination device 60 may display a list of "correct" or "incorrect" determinations for all of the spare rolls of paper 220 (six in total) arranged 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 the 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.

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

The above explanation is based on the assumption that the determination device 60 is a separate component 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, a single RFID reader 20 can be used to serve as both the RFID reader 20 of the determination device 60 and the RFID reader 20 of the remaining amount detection device 10.

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

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 corrugated paper, but also to processing equipment that performs manufacturing and other processes using roll bodies in which sheet-like, long materials (paper, cloth, resin, metal) are wound into a roll, not limited to corrugated paper.
