Description

The present invention relates to a roll body determination device.

A corrugated board sheet is manufactured by laminating corrugated base paper ((front) liner (flat), corrugated medium, (back) liner (flat)) by a corrugating machine. The base paper for corrugated board is formed into roll paper wound into a roll. Rolled paper is set at a predetermined position of a corrugating machine when manufacturing corrugated cardboard sheets (see, for example, Patent Document 1).

A standby position is provided in front of a predetermined position of the corrugating machine where a spare roll of paper is placed. The roll paper is transported from a storage area such as a warehouse to a manufacturing area provided with a corrugating machine by a forklift or the like, and unloaded at a predetermined storage location. Then, the roll paper is placed on a moving body and transported along a transport path extending from the place of placement to a predetermined position of the corrugating machine via the standby position.

Here, the spare roll paper placed in the waiting place is transported to the predetermined position of the corrugating machine when the remaining roll paper used in the predetermined position of the corrugating machine runs out. , used to replace the used roll paper.

JP 2005-096311 A

However, once it has been transported to a predetermined position and set in the corrugating machine, if an error in the specification of the transported roll paper is noticed, the roll paper is retracted from the predetermined position and the correct specification is set. Extra setup is required, such as transporting the roll paper from the storage area and rearranging it in a predetermined position.

As a result, the time during which the corrugating machine is stopped becomes longer than when roll paper with correct specifications is arranged at a predetermined position, and the operating efficiency of the corrugating machine is reduced.

It should be noted that the above-mentioned problem is not limited to the roll paper of the corrugated board used in the corrugating machine. The same problem may occur in a processing apparatus that performs processing such as manufacturing using .

Hereinafter, an embodiment of a roll body determination device according to the present invention will be described 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. 2 is a perspective view showing the roll paper 200 to be managed by the roll paper 200 management system shown in FIG. 1, and FIG. 3 is a flowchart showing general operations of the roll paper 200 management system shown in FIG.

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, and a remaining amount. A detection device 10 and a determination device 60 are provided.

The roll paper 200 is, for example, a long sheet-like corrugated board base paper 202 (see FIG. 2) wound into a roll, which is set in a corrugating machine to manufacture corrugated board 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 diametrical direction. 203 are provided respectively. The reinforcing tube 203 is made of, for example, a metal material, and is provided to prevent the corrugated board base paper 202 around the cavity 201 from being deformed when the support shaft of the corrugating machine 400, which will be described later, is inserted.

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

In this embodiment, when the roll paper 200 is newly received (first time) (YES in step 1 (S1) of the flowchart in FIG. 3), the barcode of the barcode label 110 attached to the roll 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. FIG.

The specification information of the cardboard base paper 202 corresponding to the barcode may not be stored in the barcode reader 130 itself, and may be obtained from an external device such as the server 150 .

RFID label issuing machine 140 issues RFID label 120 (RFID tag) having an IC chip storing an identification code (ID) corresponding to the barcode input from barcode reader 130 (S3 in FIG. 3). The RFID label 120 issued by the RFID label issuing machine 140 is attached to the incoming roll paper 200 manually by an operator or automatically by a robot. The roll paper 200 to which the RFID label 120 is attached is transferred and stored in a predetermined storage area.

4 to 6 are diagrams showing aspects of the position where the RFID label 120 is affixed to the roll paper 200, and FIG. FIG. 5 is a cross-sectional view of a main part showing a mode of attachment to the reinforcing cylinder 203 facing the cavity 201 of the roll paper 200, and FIG. is a cross-sectional view of a main part showing

Here, for example, as shown in FIG. 4, the RFID label 120 may be attached to a portion of the cavity 201 of the roll paper 200 that is not in contact with the reinforcing tube 203, that is, a non-metallic portion of the roll paper 200. As shown in FIG. 5, in the cavity 201 of the roll paper 200, it may be attached to the reinforcement cylinder 203. As shown in FIG. You may attach it so that it straddles.

Since it is generally desirable to place the RFID label 120 away from metal parts, the placement shown in FIG. 4 is preferable. When such an RFID label 120 is applied, it may be arranged as shown in FIGS.

The RFID label issuing machine 140 outputs to the server 150 the identification code stored in (the IC chip of) the issued RFID label 120 and the bar code or specification information of the cardboard base paper 202 obtained from the outside.

A server 150 , which is an example of a management device, includes a database 160 and an update section 170 . The database 160 associates and stores the identification code (ID) input from the RFID label issuing machine 140 and various types of information such as specification information and inventory information of the cardboard base paper 202. The identification code of the received roll paper 200 and the specification information are associated with each other and registered in the database 160 (S4 in FIG. 3).

FIG. 7 is a diagram showing an example of a specific database 160. As shown in FIG. An example of a specific database 160, as shown in FIG. 7, includes paper type, first receipt date, last use date, remaining amount (remaining length) as an example of specification information, and storage as an example of inventory information. A zone is associated with an identification code. Note that the specific contents of the database 160 are not limited to the example shown in FIG.

The update unit 170 rewrites the length in the specification information of the cardboard base paper 202 stored in the database 160 with the remaining amount of the cardboard base paper 202 in the roll paper 200 output from the remaining amount detection device 10 described later, or rewrites the stock information. to update the information.

Inventory information in the database 160 is updated when an RFID reader 180 for inventory management, which will be described later, reads the RFID label 120 of the roll paper 200 that is in stock in the storage area and makes an inquiry to the server 150 (S5 in FIG. 3). The storage area information for the roll paper 200 that has been updated (S6 in FIG. 3) and has been received for the first time is registered by the update at this time.

An RFID reader 180 for inventory management reads from the RFID label 120 attached to each of a large number of roll papers 200 (for example, roll papers 210, 220, . The identification code is read and collated with the database 160 of the server 150 to manage inventory information such as the presence or absence of the roll paper 200 (registration and update of the storage area in the database).

Since the RFID reader 180 can read information such as an identification code stored in the RFID label 120 without contact with the RFID label 120, it can read individual items stored in the warehouse like a barcode reader. It is not necessary to be close to the roll paper 200.

That is, the identification codes of a plurality of RFID labels 120 present in a certain range of space can be read almost simultaneously at once. A certain range is a range of distances that can be communicated between RFID reader 180 and RFID label 120. Within a certain range, RFID reader 180 can read information such as an identification code stored in RFID label 120. can be read contactlessly.

Note that the range to a certain extent depends on the specifications of the RFID reader 180 and the RFID label 120, the space conditions (whether it is a space partitioned by walls or an open space not partitioned by walls, It changes depending on the density of the arrangement of the roll paper 200 with the RFID label 120, etc.). Therefore, inventory management using the RFID label 120 can greatly reduce the labor required for inventory management of the roll paper 200 in the warehouse.

(remaining amount detector, remaining amount management system)
FIG. 8 is a block diagram showing the configuration of the remaining amount detection device 10, and FIG. 9 shows a corrugating machine 400 (an example of a processing device) that manufactures corrugated cardboard sheets using roll paper 200 set at predetermined positions 410, 420, and 430. It is a schematic diagram which shows a part.

The remaining amount detection device 10 includes an RFID reader 20, a sensor 30, and an output section 40, as shown in FIG. For example, as shown in FIG. 9, the remaining amount detecting device 10 is provided at predetermined positions 410, 420, and 430 at which the roll paper 200 is set in a corrugating machine 400 that unwinds the cardboard base paper 202 from the roll paper 200 to manufacture a corrugated cardboard sheet. are placed in the vicinity of The remaining amount detection device 10 is configured separately from the corrugating machine 400 .

The roll paper 200 is set at a predetermined position 410, as shown in FIG. 11, which will be described later. Roll paper 200 is placed on transfer body 470 , and roll paper 200 is set at predetermined position 410 by moving body 470 carrying roll paper 200 along transport path 450 to predetermined position 410 . Setting the roll paper 200 to other predetermined positions 420 and 430 is the same.

The range arranged 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. , 420 and 430 in which the RFID labels 120 of the roll paper 200 can be read.

That is, the RFID reader 20 placed near the predetermined position 410 communicates with the RFID label 120 on the roll paper 200 placed at the predetermined position 410 with the direction of the transmitted radio wave and the strength of the electric field adjusted in advance. is set so that information such as the stored identification code can be read.

With the same setting, the RFID reader 20 placed near the predetermined position 420 can read the information such as the identification code of the RFID label 120 of the roll paper 200 placed at the predetermined position 420 . The RFID reader 20 placed at the 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 predetermined position 410 in a non-contact manner. The sensor 30 detects the diameter or radius of the roll paper 200 by irradiating the roll paper 200 with laser light, for example. The sensor 30 also has 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 defined by the specifications of the roll paper 200, it may be stored in advance by the calculation unit, or communicated with the server 150 by the output unit 40 provided in the remaining amount detection device 10. , the specification information of the roll paper 200 stored in the database 160 of the server 150 may be obtained.

The sensor 30 is not limited to detecting the diameter and radius of the roll paper 200 using a laser beam, as long as it detects the remaining amount of the cardboard base paper 202 of the roll paper 200 . Therefore, the diameter and radius of the roll paper 200 may be detected by a method other than the laser beam, or a physical quantity different from the diameter and radius of the roll paper 200 may be detected.

A physical quantity different from the diameter and radius of the roll paper 200 is detected, for example, the number of revolutions per hour (rotational speed) of the cardboard base paper 202 from the roll paper 200 during operation of the corrugating machine 400 . Since the corrugating machine 400 manufactures corrugated board sheets at a constant speed, the speed at which the roll paper 200 is unwound and the corrugated board base paper 202 is fed out is constant.

The rotational speed of the roll paper 200 rotated by feeding the cardboard base paper 202 is defined by the diameter or radius of the roll paper 200 . That is, the roll paper 200 rotates faster as its diameter or radius decreases. Therefore, by detecting the rotation speed of the roll paper 200, the sensor 30 detects the remaining amount of the cardboard base paper 202 of the roll paper 200 in relation to the constant speed for manufacturing the cardboard sheet (the delivery speed of the cardboard base paper). be able to.

The constant speed for manufacturing the corrugated board sheet (the speed at which the corrugated board base paper is fed out) can be obtained in advance when the corrugating machine is operated.

The output unit 40 outputs information in which 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 are associated with each other.

Information in which the identification code of the roll paper 200 and the remaining amount of the cardboard base paper 202 are associated with each other, which is output from the output unit 40, is input to the server 150 (S7 in FIG. 3). The server 150 identifies the roll paper 200 corresponding to the input identification code of the roll paper 200 from the information stored in the database 160, based on the associated information, and updates the roll paper 200. The remaining amount of the specification information corresponding to the identification code 200 is rewritten to the remaining amount of the input corrugated board 202 (update; S8 in FIG. 3).

As described in detail above, the remaining amount detection device 10 for the roll paper 200 is configured as follows. That is, the remaining amount detection device (remaining amount detection device 10) of the roll body (roll paper 200) detects a roll body (roll paper 200) in which a long sheet-like material (cardboard base paper 202) is wound in a roll shape. An RFID reader (RFID reader 20) for contactlessly reading the identification code from the attached RFID tag (RFID label 120) storing the identification code for specifying the roll body, and the remaining amount or amount of use of the material and the identification code read by the RFID reader and the remaining amount of the material detected by the sensor are associated with each other, or the read by the RFID reader an output unit (output unit 40) that associates the identification code with the amount of use detected by the sensor and outputs the amount to a server (server 150) that stores the remaining amount of material for each roll body; there is Then, the remaining amount detection device 10 is provided at predetermined positions (predetermined positions 410, 420, 430) where the roll body is arranged in a processing device (corrugating machine 400) that unwinds and uses the material from the roll body. placed in the vicinity.

With this configuration, according to the remaining amount detecting device 10, the remaining amount of the corrugated board 202 wound on the roll paper 200 can be independently acquired. No need to get quantity.

Therefore, the remaining amount detection device 10 can automatically acquire and manage the remaining amount of cardboard base paper in the roll paper 200 without depending on the corrugating machine 400 .

In addition, since the sensor 30 in the remaining amount detection device 10 detects the remaining amount without contacting the roll paper 200, the contact resistance with respect to the roll paper 200 is similar to that of a sensor that contacts the roll paper 200 to detect the remaining amount. Therefore, the operation of the corrugating machine 400 is not affected.

Note that 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 base paper 202, the feed length of the cardboard base paper 202 (=peripheral length×rotation speed; use amount) can be detected.

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

With this configuration, according to the remaining amount management system 300, the remaining amount of the corrugated cardboard base paper 202 wound on the roll paper 200 can be independently obtained. No need to get quantity.

Therefore, the remaining amount management system 300 can automatically acquire and manage the remaining amount of cardboard base paper in the roll paper 200 without depending on the corrugating machine 400, thereby reducing the labor and cost of roll paper inventory management. can be reduced.

The above description is for the remaining amount detecting device 10 when the roll paper 200 is set at the predetermined position 410 of the corrugating machine 400. , other remaining amount detection devices 10 have the same configuration and have the same effect.

Further, although the remaining amount detection device 10 is arranged near the predetermined position 410 of the corrugating machine 400, it is not limited to being arranged near the predetermined position 410 of the corrugating machine 400 or the like.

That is, the remaining amount detection device of the roll body and the remaining amount detection device of the remaining amount management system arrange the sensor 30 and the RFID reader 20 in the vicinity of the predetermined position 410 etc. of the corrugating machine 400, The output unit 40 may be arranged in the sensor 30 and the RFID reader 20 and the output unit 40 may be wirelessly connected.

Further, 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 on the roll paper 200 can be obtained independently. , there is no need to acquire from the corrugating machine 400 by modifying the corrugating machine 400 or the like.

The sensor 30 in the remaining amount detection device 10 detects the amount of remaining cardboard base paper 202. Physical quantities detected by the sensor 30 include the radius or diameter of the roll paper 200 described above and the rotational speed of the roll paper 200. Not limited. That is, the sensor 30 may detect the length (used amount) of the roll paper 200 to the cardboard base paper 202 used by the corrugating machine 400 .

In this case, the sensor 30 may detect the feed length of the corrugated board 202 fed by the corrugating machine 400 . The remaining amount (initial value) of the cardboard base paper 202 before the roll paper 200 is set at the predetermined position 410 of the corrugating machine 400 is stored in the database 160 .

Therefore, when the sensor 30 detects the amount of corrugated board 202 used by the corrugating machine 400, the calculation of subtracting the usage fee from the remaining amount (initial value) obtained from the database 160 results in the sensor 30 detecting the corrugated board 202. 202 remaining amount can be obtained.

If the corrugating machine 400 is equipped with a monitor that displays the amount of cardboard paper 202 remaining or used in the roll paper 200 currently set at the predetermined position 410, the monitor A camera device that captures the displayed remaining amount or usage amount and obtains an image of the remaining amount or usage amount obtained by capturing as numerical data by performing image recognition processing may be applied as the sensor 30. can. In other words, the sensor 30 may be of any type as long as it acquires the remaining amount of the cardboard base paper 202 of the roll paper 200 set at the predetermined positions 410 , 420 , 430 .

(Determination device)
FIG. 10 is a block diagram showing the configuration of a roll paper determination device 60 according to an embodiment of the present invention, and FIG. FIG. 10 is a diagram schematically showing a state in which it is arranged near a spare roll paper 220 (200) arranged at a standby position 411 on a transport path 450;

The determination device 60 is an embodiment of the roll body determination device according to the present invention, and includes an RFID reader 20, a collation unit 70, and a determination output unit 80, as shown in FIG. For example, as shown in FIG. 11, the determination device 60 is in the vicinity of the spare roll paper 220 arranged at the standby position 411 of the same transport path 450 as the roll paper 210 set at the predetermined position 410 of the corrugating machine and used. placed in

The roll paper 220 placed on the transfer body 460 and placed at the standby position 411 is a spare roll that is used when the remaining amount of the cardboard base paper 202 in the roll paper 210 currently used in the corrugating machine 400 runs out. Paper. 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 is placed on the transfer body 460 along the transport path 450 to the predetermined position 410 . It advances and is set at a predetermined position 410 in place of the roll paper 210 . Then, the roll paper 220 placed at the predetermined position 410 is used for manufacturing corrugated cardboard sheets by the corrugating machine 400 .

The RFID reader 20 communicates only with the RFID label 120 of the roll paper 220 placed at the standby position 411 and reads information such as the stored identification code. , and does not read information such as an identification code stored in the RFID label 120 of the roll paper 210 .

The collation unit 70 communicates with the server 150 and acquires the correct specifications of the roll paper 200 to be placed at the predetermined position 410 (such as the paper type of the cardboard base paper 202 ) from the production plan of 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 corrugated cardboard sheets by the corrugating machine 400 . The production plan includes the correct specifications of the roll paper 200 required in correspondence with the production plan for manufacturing corrugated cardboard sheets by 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 at the standby position 411 read by the RFID reader 20 . Then, the collation unit 70 collates the specification information corresponding to the identification code of the roll paper 220 acquired from the database 160 with the correct specification acquired from the production plan held by the server 150, so that the specification of the roll paper 220 is corrugated. The result of checking whether or not it matches the correct specification to be set at the predetermined position 410 of the machine 400 is output to the determination output section 80 .

The determination output unit 80 is, for example, a display device, and the specification of the roll paper 220 set at the standby position 411 input from the collating unit 70 matches the correct specification to be set at the predetermined position 410 of the corrugating machine 400. The judgment is displayed (output) according to the collation result of whether or not.

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

When the judgment output unit 80 displays the judgment “wrong”, the judgment output unit 80 displays the judgment “wrong” in order to notify the surrounding workers that the roll paper 220 set at the standby position 411 has the wrong specifications. ” is displayed prominently. Specifically, the judgment output unit 80 displays the display of the judgment “wrong” in a color that is easy for the operator to see, or blinks the display.

Further, the determination output unit 80 may generate an alarm sound to notify the operator instead of making the display conspicuous, or in combination with making the display conspicuous.

Then, when the roll paper 220 waiting at the standby position 450 is judged to be "wrong", the judgment output unit 80 instructs not to automatically move the transfer body 460 from the standby position 450 to the predetermined position 410. A signal is output to transport body 460 to keep roll paper 220 stopped at standby position 450 .

On the other hand, when the determination of the roll paper 220 is “positive”, the determination output unit 80 outputs the spare roll paper 220 at the standby position 411 to the predetermined position when the remaining amount of the roll paper 210 at the predetermined position 410 is exhausted. It outputs an instruction signal to transport 460 to allow it to be automatically transported to 410 .

As described in detail above, the roll paper determination device 60 of the present embodiment is configured as follows. That is, the roll body (roll paper) determination device 60 of the present embodiment has a long sheet-like paper which is arranged at a standby position (standby position 411) before being arranged at a predetermined position (predetermined position 410). An RFID reader (RFID reader 20) that reads the identification code stored in the RFID tag (RFID label 120) from the RFID tag (RFID label 120) of the roll body (roll paper 220) in which the material (cardboard base paper 202) is wound in a roll shape. and obtaining the correct specifications of the roll body to be placed at the predetermined position, and reading the obtained correct specifications and the specifications corresponding to the identification code of the roll body at the standby position read by the RFID reader. A collation unit (collation unit 70) that collates and outputs a collation result, and a judgment output unit (decision output unit 80) that outputs a judgment as to whether or not the specification of the roll body at the standby position is correct according to the collation result. ), and

With this configuration, according to the roll paper determining apparatus 60 of the present embodiment, the roll arranged at the standby position 411 as a spare roll paper for the roll paper 210 arranged at the predetermined position 410 and used in the corrugating machine 400 Before the roll paper 220 is actually set at the predetermined position 410, it can be automatically determined whether the paper 220 has the correct specifications as a spare roll paper.

If the collation result indicates that the roll paper 220 has incorrect specifications, the roll paper 220 that is stopped at the standby position 411 is retracted from the standby position 411 by manual operation or the like, and the roll paper 200 that has the correct specifications is displayed. to the standby position 411 .

As a result, the operating efficiency of the corrugating machine 400 can be improved as compared with the case where the wrong specification roll paper 220 is actually placed at the predetermined position 410 and the specification error is noticed at that timing.

That is, if the wrong specification roll paper 220 is placed at the predetermined position 410 and the specification error is noticed at that timing, the roll paper 220 is withdrawn from the predetermined position 410 and the correct specification roll paper is placed at the predetermined position. Extra setup for relocating to 410 occurs. As a result, the corrugating machine 400 is stopped for a longer period of time than in the case where such unnecessary setup does not occur, and the operating efficiency of the corrugating machine 400 is reduced.

However, the determination device 60 of the present embodiment can determine that the roll paper 220 with the wrong specifications is incorrect at the standby position 411 before it is placed at the predetermined position 410 . While the corrugating machine 400 is operating while the corrugating machine 400 is in operation, the incorrect specification roll paper 220 can be replaced with the correct specification roll paper, and the corrugating machine 400 is stopped. The corrugating machine 400 does not decrease in working efficiency.

In addition, since the determination device 60 does not acquire from the corrugating machine 400 information on the specifications of the corrugated board base paper 202 used for manufacturing by the corrugating machine 400, the corrugating machine 400 does not need to be modified.

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 at the standby position 411 without depending on the corrugating machine 400 .

In the determination device 60 of the present embodiment, the determination output unit 80 itself outputs determination display and sound. The judgment may be output to an external monitor or the like, and the judgment may be displayed on the monitor or an alarm sound may be generated.

FIG. 12 shows a list of "correct" or "wrong" judgments for the spare roll paper 220 that is connected wirelessly or by wire to each judgment device 60 and placed in all the standby positions 411, 421, and 431. 90 is a diagram showing an example of a display of a screen displayed on 90. FIG.

For example, as shown in FIG. 9, two roll papers 200 and 200 in use are placed at a predetermined position 410, two roll paper rolls 200 and 200 in use are also placed at a predetermined position 420, and a predetermined position 430 is provided. In the corrugating machine 400 in which the two roll papers 200, 200 in use are arranged, standby positions 411, 421, 431 corresponding to the paper rolls 200 in use at predetermined positions 410, 420, 430, respectively. Two spare roll papers 220 are arranged in each of the positions.

Therefore, the determination device 60 corresponding to each spare roll paper is arranged, and the determination output unit 80 of each determination device 60 is connected to each determination device 60 wirelessly or by wire as shown in FIG. The monitor 90 (display device) displays a list of "correct" or "wrong" judgments for the spare roll paper 220 (six in total) placed at all of these standby positions 411, 421, and 431. may The external monitor 90 may be connected to each determination device 60 via the server 150 . Although the external monitor 90 is separate from the determination device 60 , it may be a part of the constituent elements of the determination device 60 .

In this way, by outputting a list of determinations of a plurality of spare roll papers 220 to one monitor 90 , it is possible to collectively check the determinations of a plurality of spare roll papers 220 on one monitor 90 . This can reduce labor for confirmation compared to going around to confirm the judgment of each judgment device 60 .

Although the above description is based on the premise that the determining device 60 has a configuration different from the remaining amount detecting device 10 , the determining device 60 may be incorporated into the remaining amount detecting device 10 . In this case, one RFID reader 20 can be used in common as 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, the remaining amount management system 300, and the determination device 60 of the present embodiment employ roll paper 200, in which long sheet-like cardboard base paper 202 is wound into a roll, as a roll body. A corrugating machine 400 for unwinding and using corrugated board base paper 202 from roll paper 200 is applied as a processing device.

However, the apparatus for detecting the remaining amount of roll bodies, the system for managing the remaining amount of roll bodies, and the apparatus for determining the remaining amount of roll bodies according to the present invention are not limited to cardboard base paper. It is applicable not only to a corrugating machine but also to a processing apparatus that performs processing such as manufacturing by using the rolled body.
