(J-3) Normal operation time Indicates the operation time during which the shredding process is performed by the shredding mechanism 35. For example, by accumulating the time under load with respect to the drive current value of the drive motor 51 under no load. can get.
(J-4) Number of normal operations This indicates the number of operations in which the shredding process is performed by the shredding mechanism 35, and is obtained by accumulating the number of detections of the inlet sensor 81, for example.
(J-5) Overload operation time During the operation in which the shredding mechanism 35 is performing the shredding process, the load of the drive current value of the drive motor 51 is a predetermined threshold value due to the excessive amount of paper loaded. This is the cumulative total of the above overload times.
(J-6) Number of overload operations During the operation in which the shredding mechanism 35 is performing the shredding process, the load of the drive current value of the drive motor 51 is a predetermined threshold value due to the excessive amount of paper loaded. This is the cumulative number of times the above overload conditions have been reached.

(J-7) Number of Auto-Reverses The auto-reverse process prevents a paper jam in the shredding mechanism 35 when a high-load paper S having a shredding processing capacity or more is loaded into the shredding mechanism 35. Therefore, the inserted paper S is returned by reversing the drive motor 51 and discharged from the input port 32. For example, it is obtained by counting the number of reversals of the drive motor 51 during operation of the shredding mechanism 35. Be done.

(J-SR) Usage history information In this example, the cumulative shredding amount of the paper S when the shredding process by the shredding mechanism 35 is repeatedly performed is used. This cumulative shredding amount is obtained by accumulating the shredding amount calculated by the following formula.
Cumulative shredding amount = Σ (operating time x shredding load)
Here, the'operation time'refers to the normal operation time in each shredding process by the shredding mechanism 35, and the'shred load' refers to the load during the shredding process by the shredding mechanism 35, specifically, the drive motor 51. It corresponds to the drive current ratio and corresponds to the number of sheets to be shredded at the same time. That is, as shown in FIG. 5A, the drive current I is the number of sheets to be shredded at the same time, assuming that the shredding process by the shredding mechanism 35 can shred a plurality of sheets S at the same time. It increases proportionally as the number of shredded sheets increases. At this time, the difference between the drive current I (1) when the number of shredded sheets is one and the drive current I (0) when there is no load is ΔI (1), and the number of shredded sheets is n (n: 2 or more). If the difference between the drive current I (n) when the number of sheets is) and the drive current I (0) when there is no load is ΔI (n), the relationship of ΔI (n) / ΔI (1) ≈n is satisfied. Therefore, in the shredding process by the shredding mechanism 35, the shredding amount is calculated in consideration of the number of sheets to be shredded at the same time, and when this is accumulated, the cumulative shredding amount is calculated.

Further, the drive current I of the drive motor 51 shows If as shown in FIG. 5B when the shredder 30 is operated without load in the initial state (new), but after a certain period of time, the cumulative current is small. As the amount of shredder increases (for example, 1t to 3t), it tends to increase as Ia, Ib, and Ic (If <Ia <Ib <Ic).
This is because when the shredding mechanism 35 is used over time, the cutter element of the shredding mechanism 35 may be jammed with paper dust, shredded waste, or the like, or the cutter element may be worn. Therefore, it is presumed that the shredding load by the shredding mechanism 35 increases even during no-load operation.
Therefore, if the drive current I during no-load operation of the drive motor 51 is monitored regularly or irregularly, the degree of deterioration of the cutter element of the shredding mechanism 35 (paper) is observed by observing the monitor change. It is possible to grasp (clogging, wear).
Further, since the drive current I during the shredding process by the shredding mechanism 35 also changes with the deterioration of the shredding mechanism 35, the drive measured based on the degree of deterioration of the shredding mechanism 35 is taken into consideration. If the current I is corrected, the shredding load in each shredding process is calculated more accurately, which is preferable in that the cumulative shredding amount is calculated more accurately.

(J-ER) Error history information For example, when the shredding process by the shredding mechanism 35 is stopped due to the paper S being jammed, the detection operation of various sensors (input port sensor 81, waste full sensor 82, etc.) becomes unstable. In this case, the error code determined in advance as the type of error and the time of occurrence thereof are indicated for these malfunctions.

-Management device-
In the present embodiment, as shown in FIG. 7, the management device 100 is communicably connected to the network X via the communication modem 110, and the collection worker W can access the management server 120 through the mobile terminal 200. (In this example, a so-called web server is used), and the management server 120 is provided with a customer database 130 in which information (mainly operation status information) of the managed shredder 30 is updatable, and the administrator M is provided with the customer database 130. The customer database 130 can be browsed.
In particular, in this example, when the management device 100 diagnoses the necessity of the collection work for the shredded waste Sa that has been shredded and discarded by the managed shredder 30 based on the customer database 130, and the collection work is necessary. It has a work diagnosis unit 140 capable of selecting a collection worker W and creating a collection work instruction 141 for shredded waste toward the selected collection worker W.
Then, in this example, the management device 100 executes the shredder management process as shown in FIG. 9, for example.
Then, the collection worker W refers to the collection work instruction 141 transmitted from the management device 100 to the mobile terminal 200, goes to the customer U, and collects the shredded waste Sa generated from the managed shredder 30. Is to be implemented.

<Customer database>
Examples of the customer database 130 used in this example include those shown in FIG. 7 (b).
In the figure, the customer database 130 includes user information 131, aircraft information 132, operation status information 133, usage history / error history, and other information 134, and is updated every time information is received from the managed shredder 30. It is supposed to be done.
Here, the user information 131 includes, for example, a company name, an address, a person in charge, a contact information, a delivery date, and the like, and the aircraft information 132 includes a model name, a serial number, and the like, and further, an operation status information 133. Examples include normal operation time, number of normal operations, and the number of detections of various sensors, and usage history / error history and other information 134 include cumulative shredder amount (for example, predetermined specified values), various error codes, and various error codes. In addition, the display of the occurrence time, the transmission request condition in the case where the administrator M side periodically requests the management target shredder 30 to transmit, and the like can be mentioned.
In this example, as one of the operation status information 133, in order to diagnose the degree of deterioration of the cutter element of the shredding mechanism 35, the drive current value of the drive motor 51 during no-load operation is periodically set from the initial operation. Alternatively, it is measured and stored irregularly, and this is also stored in the customer database 130.

-Processing on the managed shredder side-
The control device 70 of the managed shredder 30 executes, for example, the shredder communication control program shown in FIG.
As shown in the figure, the control device 70 first determines whether or not the shredding process is performed by the shredding mechanism 35, and if the shredding process is performed, confirms the shredding execution conditions. For example, while checking the normal operation time, the number of normal operations, the drive current of the drive motor 51, etc., various machine information (overload operation time, overload operation number, autoreverse number, heat dissipation number, various sensors) associated with the shredding process are confirmed. Collect the number of detections, etc.).
Then, the shredding amount by the shredding mechanism 35 is calculated based on the above-mentioned shredding execution conditions, and the cumulative shredding amount is calculated by accumulating the shredding amount up to now.
After that, the control device 70 checks whether or not the calculated cumulative shredding amount has reached a predetermined specified value, and reaches the time for transmitting information to the administrator M under the condition that the specified value is reached. It is determined that this has been done, and the necessary information (see FIG. 7A) is transmitted to the administrator M.
In the information transmission process, it is preferable to perform pre-processing (password confirmation, etc.) for ensuring security with the communication destination.
Further, when the control device 70 determines that the transmission time has not been reached based on the cumulative shredding amount, it is checked whether or not there is a warning notification or whether or not there is a transmission request from the administrator M. After that, if there is no request, the information transmission process is not executed, and if there is any request, the necessary information is transmitted to the administrator M according to the request.
Here, the'warning notification'notifies a warning that the managed shredder 30 is likely to cause a situation that hinders the continuation of normal operation. For example, the waste full sensor 82 (see FIG. 4). When the number of detections of the above reaches a predetermined threshold value of k times, a warning is given when the shredder scrap Sa is full and it becomes difficult to continue the shredder processing by the shredder mechanism 35. be.

-Processing on the management device side-
The management device 100 is designed to execute, for example, the shredder management program shown in FIG.
In the figure, the management device 100 determines whether or not to request transmission to the managed shredder 30. At this time, for example, it is checked whether or not it matches the transmission time information added to the usage history / error history and other information 134 of the customer database 130.
Then, when there is a transmission request from the administrator M side, the transmission request is made to the managed shredder 30.
On the other hand, if there is no transmission request from the administrator M side described above, it is determined whether or not there is a direct request from the collection worker W, and if there is a request from the collection worker W, it is a management target. A transmission request is made to the shredder 30, and if there is no request from the collection worker W, whether or not the reception is from the managed shredder 30 is constantly monitored, and if the reception is from the managed shredder 30, the reception is received. to approve.
After that, as shown in FIG. 7, the management device 100 reads the information transmitted from the managed shredder 30 and updates the customer database 130 of the management server 120.
Then, the managed shredder 30 is diagnosed from the information transmitted by the work diagnosis unit 140, and when it is diagnosed that the shredder waste collection work is necessary, the collection work instruction 141 to be sent to the collection worker W is sent. create.

Here, the details of the processing by the work diagnosis unit 140 are as follows.
(1) Judgment process regarding the necessity of collection This determines the necessity of collecting the shredder Sa generated from the managed shredder 30 based on the shredder information of the managed shredder 30 of the customer database 130. In this example, for example, as shown in FIG. 10, the cumulative shredder amount is T, and the specified value that requires the collection work of the shredder waste Sa (for example, the waste container 37 is full at the request of the customer U). Assuming that T1 is a specified value that can be selected in advance by an integral multiple of the resulting amount, it is determined that the shredded waste Sa needs to be collected under the condition that T = T1.
Then, in this example, when the information of the cumulative shredding amount T1 as the shredding waste information is used as the collection work information of the shredded waste Sa, the cumulative shredding amount T1 in the customer database 130 is reset and the cumulative shredding amount T1 is reset. The cumulative calculation of the cut-off amount T1 is restarted.
(2) Selection process of recovery worker W Under the condition that it is determined in the discrimination process that the shredder 30 to be managed needs to collect shredded waste Sa, the recovery worker W suitable for the shredder 30 to be managed is W. Is selected.
At this time, the preferred selection method of the collection worker W is, for example, in a mode in which the mobile terminal 200 is provided with a GPS function, the collection worker W as a collection base is used from the position of the mobile terminal 200 by using the GPS function. Since it is possible to grasp the current position of the collection worker W, the collection worker W who is finally in charge may be selected as a selection candidate for one or more collection bases close to the management target shredder 30 which is the collection destination. ..
(3) Process for Creating Collection Work Instructions When the collection worker W for the managed shredder 30 is selected, the collection work instruction 141 to be transmitted to the selected collection worker W is created.
Here, as the description content of the collection work instruction 141, the information necessary for the collection worker W to go to the location of the customer U of the managed shredder 30 or the like and carry out the collection work of the shredded waste Sa is described. You can do it like this.
For example:
-Location of customer U-Aircraft information of shredder 30 to be managed-Collection amount of shredder sa Since the shredded size of the shredded waste is grasped, for example, as the delivery destination, the administrator M is determined from the shredded size and the collected amount of the shredded waste Sa in consideration of the one that reuses and recycles the shredded waste Sa. do.

-Processing on the recovery worker W side-
When the collection worker W acquires the collection work instruction 141 sent from the administrator M to the mobile terminal 200, when accepting the job, the collection worker W transmits an acceptance notification from the mobile terminal 200 to the management device 100.
After that, the collection worker W confirms the convenience of the visit to the customer U of the managed shredder 30, and then goes to the customer U to collect the shredded waste Sa for the managed shredder 30.
At this time, as shown in FIG. 6, since the shredded waste Sa generated from the managed shredder 30 is housed in, for example, the waste bag 90, the collection worker W puts the collection source information in the waste bag 90. , The waste collection label 91 on which the shredder information (for example, shred size, collection amount of shredder waste, etc.) and the delivery destination information are described is attached, and the waste bag 90 is collected. Hand over the document that the collection work of shredded waste Sa is completed.
It is preferable that the disposal / recovery label 91 is prepared in advance so that it can be attached together with the recovery work instruction sheet 141, for example.
In this state, the collection worker W transmits a collection completion notification of the shredded waste Sa from the mobile terminal 200 to the manager M (management device 100). As a result, the manager M can grasp the progress of the work status by the collection worker W. Then, the collection worker W carries in the shredded waste Sa collected directly or via another person in charge to the delivery destination.

-Outline of shredded waste management in Embodiment 1-
FIG. 11 schematically shows the mutual relationship between the customer U, the manager M / management center, and the collection worker W in the shredder shredder management system according to the present embodiment.
According to the figure, it is as follows.
(1) The manager M collects information (airframe information / operation status information) from the managed shredder 30 owned by the customer U.
(2) The manager M issues a collection work instruction to the collection worker W when the collection work conditions for the shredded waste Sa are satisfied.
(3) The collection worker W carries out the collection work of the shredded waste Sa generated from the managed shredder 30 of the customer U.
(4) The collection worker W carries the collected shredded waste Sa to the delivery destination (processing company Q).

-Outline of maintenance / repair management in Embodiment 1-
In the present embodiment, since the management device 100 collects the machine information and the operation status information of the shredder 30 to be managed, the maintenance / repair management of the shredder 30 to be managed is also carried out in addition to the above-mentioned shredder management. It is possible.
1. 1. Maintenance management of shredder Now, as shown in FIG. 10, when the cumulative shred amount T = T2 (for example, 1t), if the maintenance and inspection time is selected in advance, management as shown in FIG. 5B, for example. By checking the value of the drive current I of the drive motor 51 during no-load operation of the target shredder 30, it is possible to estimate the degree of deterioration (paper jam, wear) of the cutter element of the shredding mechanism 35. Based on this data check, for example, a maintenance / repair work instruction 142 is created. If the value of the drive current I of the drive motor 51 described above increases beyond the predicted range, it is diagnosed that the degree of deterioration of the shredding mechanism 35 is more advanced, and that is the case. Additional information is added.
As a result, the administrator M sends the maintenance / repair work instruction 142 to the maintenance / repair personnel P as shown in FIG. 11 (5), and the maintenance / repair personnel P gives the maintenance / repair work instructions described above. By referring to Document 142, the operating status of the managed shredder 30 is grasped, maintenance parts and the like are prepared in advance as necessary, and the maintenance work (maintenance) of the managed shredder 30 is carried out by visiting the site.

2. Repair management of shredders As shown in FIG. 10, when the cumulative shredding amount T = T3 (for example, 3t), assuming that the guaranteed life of the shredder mechanism 35 is reached, for example, it is shown in FIG. 5 (b). By checking the value of the drive current I of the drive motor 51 during no-load operation of the shredder 30 to be managed, the degree of deterioration (paper jam, wear) of the cutter element of the shredding mechanism 35 reaches the end of its life. It is possible to judge that there is. When it is confirmed that the shredding mechanism 35 has reached the end of its life based on such a data check, a maintenance / repair work instruction 142 to that effect is created.
As a result, the administrator M sends the maintenance / repair work instruction 142 to the maintenance / repair personnel P as shown in FIG. 11 (6), and the maintenance / repair personnel P gives the above-mentioned maintenance / repair work instructions. By referring to Document 142, the operating status of the shredder 30 to be managed can be grasped, and when it is determined that the shredder mechanism 35 has reached the end of its life, a replacement part for the shredder mechanism 35 is prepared, and the shredder 30 to be managed is visited at the site. Overhaul.

-Billing process-
As shown in FIG. 9, the administrator M determines whether or not the time when the billing process is required has been reached, and when the time has reached the required time, the administrator M executes the billing calculation. Here, the time when the billing process is required may be appropriately selected, for example, a day predetermined with the user on a monthly basis.
In addition, as the billing calculation, for example, the billing amount may be determined by multiplying the cumulative shredding amount of the current month by the unit price per sheet.
Then, when the billing amount is determined, the user is notified of this. As a result, even if a user uses a high-performance shredder 30, for example, the user can use the shredder 30 by paying a charge according to the cumulative amount of shredder that has been substantially shredded. Become. Therefore, even if the shredder 30 is not purchased at a predetermined selling price, for example, the shredder 30 may be installed by rental contract and the cost (billing amount) corresponding to the shredded portion may be paid.

◎ Embodiment 2
FIG. 12 shows a main part of the shredder management system according to the second embodiment.
In the figure, the basic configuration of the shredder management system is substantially the same as that of the first embodiment, but unlike the first embodiment, the document creator 300 (for example, 300a to 300a) such as a printer or a copier that creates important documents. It has 300c), and these are also communicably connected to the management device 100 of the administrator M / management center via the network X together with the managed shredder 30 (for example, 30a to 30c), and are suitable for discarding important documents. It is configured as a system. The same components as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and detailed description thereof will be omitted here.
In the present embodiment, as shown in FIG. 13, the customers U1 to Un are the managed shredder 30 (for example, 30 (1) to 30 (n)) and the document creator 300 (for example, 300 (1) to 300 (n)). )), And the managed shredder 30 (for example, 30 (1) to 30 (n)) is a paper S which is a shredded object before being charged into the edge of the input port 32 of the shredder housing 31. Has a guide tray 38 for guiding and holding the guide tray 38, and an information reading device (for example, an image sensor) 160 is arranged at a portion facing the guide tray 38 to read the paper S placed along the guide tray 38. It has become like. Further, each of the managed shredders 30 (for example, 30 (1) to 30 (n)) is equipped with an ID reader 170, and the ID card 171 for identifying the person in charge to be used can be authenticated.
In this example, both the data read by the information reading device 160 and the data read by the ID reader 170 are recorded in the RAM 73.

Further, in the present embodiment, the document creation source 300 (for example, 300 (1) to 300 (n)) composed of a printer, a copier, or the like has metadata (summary of document features such as title and number of sheets) for important documents. Is written in advance or after the fact.
This type of metadata may be visible on the document or in a hard-to-see format (eg, created in yellow), such as a printer or copy from the document creator 300. When printing or copying with a machine or the like, it is printed or copied together with other information.
Then, in this example, the information reading device 160 is readable even if the metadata is created in a format that is difficult to see.
In the present embodiment, the managed shredder 30 and the management device 100 perform the disposal information recording process as shown in FIG. 14 when the paper S to be discarded by the managed shredder 30 is an important document. ing.

In the present embodiment, the shredder management system has substantially the same operation as that of the first embodiment, and also performs the disposal information recording process as shown below.
In this type of disposal information recording process, as shown in FIG. 14, when the paper S as a shredded object is shredded and discarded by the managed shredder 30, the information reading device 160 converts the information on the paper S into information. It is read and processed to determine whether it is an important document with metadata.
At this time, if the paper S has metadata, as shown in FIG. 15A, the paper S is shredded and discarded, and the disposal information is recorded. That is, if there is metadata, the ID information (corresponding to the ID card 171 information by the ID reader 170) is authenticated, and the metadata, ID information, and machine information are recorded as discard information in the RAM 73 of the management target shredder 30.
In this example, the disposal information is further transmitted and recorded to the management device 100, and the disposal information is transmitted and recorded to the document creator 300 of the important document.
As described above, in the present embodiment, when important documents are shredded and discarded, the disposal information record is left for the managed shredder 30, the management device 100, and the document creator 300. It is preferable that the facts of disposal are recorded and stored as evidence.
On the other hand, it is judged that the paper S without metadata is not an important document, the paper S is shredded and discarded by the managed shredder 30, and the disposal information recording is not performed.

◎ Embodiment 3
FIG. 16 shows a main part of the shredder management system according to the third embodiment.
In the figure, the basic configuration of the shredder management system is substantially the same as that of the first embodiment, but unlike the first embodiment, the shredder 30 to be managed by the customer U (for example, 30a) is housed in the waste container 37. A scrap amount communication device 400 for communicating information on the capacity of the shredder scrap Sa (hereinafter referred to as the scrap amount) is provided. For example, a gateway 80 (wireless LAN, Bluetooth, etc.) effective on the premises of the customer U is provided. After that, it is connected to the network X and can communicate with the management device 100 of the administrator M / management center. Then, when the management device 100 determines that the amount of waste in the waste container 37 has reached a predetermined full level based on the information from the waste amount communication device 400, the shredded waste Sa of the waste container 37 is removed. For example, after being housed in the waste container 90, the collection worker W performs the shredded waste collection work and also performs the billing process based on the cumulative shredded amount. The same components as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and detailed description thereof will be omitted here.

In the present embodiment, as shown in FIG. 16, the waste amount communication device 400 is retrofitted to, for example, the opening edge of the waste container 37, and is as shown in FIGS. 17 (a) and 17 (b). , The waste amount sensor 410 is incorporated in a part of the communication device housing 401, and the communication unit 421 having at least a transmission modem function in the communication device housing 401, the detection process by the waste amount sensor 410, and the communication by the communication unit 421. It is provided with a control device 420 that controls processing.
An internal power supply (battery) 430 or an external power supply 431 is connected to the waste amount communication device 400 via a changeover switch 432 so as to be switchable and selectable.
Further, in this example, as shown in FIGS. 17A and 17B, the waste amount sensor 410 is an optical distance sensor having, for example, a light emitting element 411 such as an LED and a light receiving element 412 such as a photodiode. The shredded scrap Sa housed in the scrap container 37 is configured by irradiating the irradiation light Bm from the light emitting element 411 diagonally downward from the opening edge position of the scrap container 37 toward the bottom of the scrap container 37. The reflected light Bm'from the surface portion is received by the light receiving element 412.
Here, in FIG. 17B, reference numeral 413 is a resistor for adjusting the amount of energization of the light emitting element 410, and reference numeral 414 is a resistor for taking out the output voltage accompanying the energization of the light receiving element 412.

Next, the operating principle of the waste amount sensor 410 will be described.
Now, as shown in FIG. 18A, as the capacity of the shredded waste Sa contained in the waste container 37 gradually increases, the surface position of the shredded waste Sa becomes d ₆ → d ₅ → in the figure. It will increase in the order of d ₄ → d ₃ → d ₂ → d _1. At this time, if the installation position of the waste amount sensor 410 is d ₀ , the distance d from the waste amount sensor 410 to the shredded waste Sa is d ₆ > d ₅ > d ₄ > d ₃ > d ₂ > d ₁ . Is. In this example, it is _{assumed that the surface position d 1} of the shredded scrap Sa is the full level of the shredded scrap Sa.
In this state, the output level of the reflected light Bm reaching the light receiving element 412 after the irradiation light Bm from the light emitting element 411 is reflected by the surface portion of the shredded waste Sa is the amount of waste as shown in FIG. 18 (b). as the light path length from the light emitting element 411 of the sensor 410 to return to the light receiving element 412 is long low, it tends to increase gradually as the optical path length becomes shorter, indicating a Vmax at the position of d _1.
Further, in this example, as shown in FIG. 18C, the waste amount sensor 410 turns on the light emitting element 411 such as an LED for a predetermined sampling time ts (for example, 1 second) in a predetermined detection cycle. The output of the light receiving element 412 (point A in FIG. 17B) may be detected, sampled at a predetermined sampling interval, and averaged, for example, to obtain the output value of the waste amount sensor 410. The averaging process is performed because the output of the light receiving element 412 varies during the shredder shredding process. The sampling method is not necessarily limited to the averaging process, and may be appropriately selected such as averaging excluding the maximum value and the minimum value.

Further, in this example, the control device 420 stores a characteristic graph (FIG. 18 (b)) of the output of the waste amount sensor 410 (output of the light receiving element 412) in a memory (not shown), and every predetermined detection cycle. Detects the output of the waste amount sensor 410, calculates information on the distance d from the corresponding waste amount sensor 410 to the shredded waste Sa (for example, 16 level waste amount level), and transmits it via the communication unit 421. do.
Further, for example, the following information is written in the memory of the control device 420 as the machine information of the managed shredder 30 and the information regarding the power supply of the waste amount communication device 400, and is transmitted together with the above-mentioned waste amount level. ing.
(1) Model name (2) Manufacturing number (3) Manufacturing lot number (4) Installation date (5) Repair history (6) Power supply (internal / external)
(7) Battery replacement / No (8) Battery replacement date (9) User name

Next, the operation of the waste amount communication device used in the present embodiment will be described.
In the present embodiment, the operation of the waste amount communication device 400 differs between the case where the external power supply 431 is used and the case where the internal power supply (battery) 430 is used. Therefore, the following cases will be described separately.
-For external power supply-
As shown in FIG. 19A, the detection operation by the waste amount sensor 410 is continuously performed while the power is being supplied from the external power supply 431, and the waste amount level by the waste amount sensor 410 is determined by the control device 420. When there is a level fluctuation, the waste amount level information is transmitted every _{t 1 (for example, 10 seconds) for a short period of time.} On the other hand, if there is no level fluctuation in a predetermined time (for example, 30 seconds), the waste amount level information is transmitted every _{predetermined time t 2 (for example, 1 hour).}

-Internal power supply-
As shown in FIG. 19B, when the internal power supply (battery) 430 is used, control is required to suppress the consumption of the internal power supply 430. In FIG. 19B, the portion indicated by B indicates the region surrounded by B in FIG. 19A.
First, the internal power supply 430 checks whether the low voltage, when it is detected that a low voltage, transmits the replacement information of the battery every time t ₃ when the predetermined _(e.g., 1 hour) ..
On the other hand, when the internal power supply 430 is not at a low voltage, the scrap amount level is determined, and the scrap amount of the shredded scrap Sa stored in the scrap container 37 is at a predetermined level (for example, the surface position of the shredded scrap Sa). There is checked whether the output level Vth) or whether the scrap quantity sensor 410 when the d _6.
At this time, when the output level of the waste amount sensor 410 is less than Vth, the determination interval of the waste amount level is t ₄ (for example, 1 minute) and the transmission interval is t ₅ (t ₅ = t _{4 in} this example). Send quantity level information. The one second of the judging interval t ₄ samples 10 times, averaging processing to equalize the level variation of the scrap quantity. It is also possible to use a process other than the averaging process, for example, using the minimum value or the maximum value.
Further, when the output level of the scrap quantity sensor 410 is above Vth is so that the surface position of Hosodankuzu Sa is located above d _6, in this case, the determination interval debris levels t ₆ (e.g., 10 seconds), the transmission interval in the _{t 7} this example sends the debris amount level information as _t 7 = _{t 6).}
If the waste amount level by the waste amount sensor 410 does not fluctuate for 30 seconds, the waste amount _{level information is transmitted every predetermined time t 2} (for example, 1 hour). However, when the determination interval of the waste amount level is t ₄ (for example, 1 minute), if the waste amount level does not fluctuate for 3 minutes, the waste amount level is _{every predetermined time t 2} (for example, 1 hour). Send information.

As described above, according to the present embodiment, the waste amount communication device 400 measures the amount of waste contained in the waste container 37, and wastes together with the machine information of the shredder 30 to be managed and the power supply information of the waste amount communication device 400. The quantity level information is transmitted to the management device 100.
As a result, the manager M / management center grasps the change in the amount of shredded waste Sa housed in the waste container 37 of the shredder 30 to be managed, and when the amount of waste reaches the full level, the collection worker W will instruct the shredder collection work, and if the waste amount communication device 400 needs maintenance work, for example, battery replacement, the maintenance / repair personnel P will instruct the maintenance work, and each work will be performed. It can be implemented quickly.

Further, in the present embodiment, the waste amount communication device 400 is retrofitted to the opening edge of the waste container 37, but is not limited to this, and is retrofitted to the inner wall of the shredder housing 31. You may. Further, in the present embodiment, one waste amount sensor is incorporated in the communication device housing, but the present invention is not limited to this, and may be installed at a plurality of locations. In this embodiment, even if the distribution of shredded waste Sa housed in the waste container 37 is biased, by averaging the outputs of a plurality of waste amount sensors, as compared with the case of one waste amount sensor, It is possible to detect a more accurate waste level.

In the present embodiment, as shown in FIG. 20 (a), an optical distance sensor is used as the waste amount sensor 410, but the present invention is not limited to this, and as shown in FIG. 20 (b). For example, a scrap amount sensor 510 that detects the weight of the scrap container 37 in which shredded scrap is stored may be used.
In the case of this example, the weight of the waste container 37 may be measured, the amount corresponding to the weight may be recorded each time, and the cumulative shredded amount may be grasped in a predetermined period.
As a more specific processing example,

In addition, even if the waste bag is replaced before it is full, the weights before and after the replacement are recorded, so that it is understood that the waste bag has been replaced.
(5) In the case of notification to the management center, it is possible to take action to collect waste before it is full depending on the content of the notification information, and it is possible to concentrate on the work without splitting the user's work. Become.
(6) Since the cumulative shredding amount can be calculated from the information from the weight sensor 510, the billing process may be performed based on this.

◎ Embodiment 4
FIG. 21 shows a main part of the shredder management system according to the fourth embodiment.
-Composition of noise reduction mechanism-
In the present embodiment, as shown in FIG. 21, a noise reduction mechanism 600 is provided in the middle of the carry-in path 33 that is inclined diagonally downward of the shredder housing 31, and the regulation roll 601 of the noise reduction mechanism 600 is provided. Focusing on the fact that the paper S moves according to the thickness of the paper S to be loaded, the thickness (number of sheets) of the paper S to be loaded is calculated from the movement amount of the regulation roll 601 and the cumulative value of the shredder's 30 shredded waste amount. Is intended to be calculated.
In this example, as shown in FIGS. 21 and 22 (a) and 22 (b), the noise reduction mechanism 600 intersects a part of the upper partition chute 33a that partitions the upper side of the carry-in path 33 in the carry-in direction of the paper S. A long rectangular mounting hole 602 extending along the width direction is provided, and a regulation roll 601 is installed at a portion facing the mounting hole 602 so as to face the lower partition chute 23b.
In this example, the lower partition chute 33b has steps on both sides of the flat plate-shaped chute body in the width direction as overhangs extending toward both ends in the axial direction (longitudinal direction) of the regulation roll 601 and is outward in the width direction. The regulation roll 601 is provided with a stepped portion 603 protruding from the surface, and the peripheral surfaces of both ends in the axial direction thereof are contacted and arranged on the stepped portion 603 of the lower section chute 33b, and the chute body of the lower section chute 33b is provided. An opening of a gap g is secured between the two. The gap g is selected to be about 0.1 mm (0.08 to 0.12 mm), assuming a size that allows one sheet S having a basis weight of about 60 to 100 g to pass through.
Further, the guide plate 605 for guiding the movement locus of the regulation roll 601 along one side edge of the mounting hole 602 of the upper partition chute 33a in the longitudinal direction is inclined by a predetermined angle (for example, 20 to 50 °) with respect to the horizontal direction. By placing the regulation roll 601 on the guide plate 605, the regulation roll 601 is arranged facing the mounting hole 602, and both ends in the axial direction of the regulation roll 601 are arranged at the stepped portion 603 of the lower partition chute 33b. Has come to be supported.

-Operation of noise reduction mechanism-
Next, the operation of the noise reduction mechanism 600 used in the present embodiment will be described.
First, as shown in FIG. 22 (a), when the object to be shredded is a sheet of paper S (specifically, S ₁ ) having a _{predetermined thickness t 1} (t _{1 <g).} , sheet S ₁ is when it is carried into the carry-in path 33 from the inlet 32, regulating roll 601 is disposed to secure a gap g a lower section chute 33b of the loading path 33 as a counter member. This gap g has an opening width narrower than the opening width in the thickness direction of _{the paper S 1} of the carry-in route 33, but is set to be larger than the thickness t _{1 of one sheet S 1, so that the paper S 1} passes through the opening of the gap g between the regulation roll 601 and the chute main body of the lower partition chute 33b, and reaches the shredding mechanism 34. At this time, the opening of the gap g between the chute body of regulation rolls 601 and lower compartment chute 33b is due to the presence of the sheet S _{1 |} g-t ₁ | merely leave a minute gap due to the shredding mechanism 34 Shredded sound is greatly attenuated in minute gaps.
Further, as shown in FIG. 22 (b), when the object to be shredded is a plurality of sheets S (specifically, S _{2 ) having a thickness t 2} having a gap g or more, the sheet S ₂ is When passing through the opening of the gap g of the regulation roll 601, the regulation roll 601 is retracted and moved, and is carried toward the shredding mechanism 34 along the lower section chute 33b of the carry-in path 33.
The opening width between the present embodiment, since the regulating roll 601 is moved to the retracted direction with the passage of strong sheet S ₂ of surface rigidity, the regulating roll 601 and the lower compartment chute 33b, the thickness of the sheet S ₂ divergence than the gap g dimensions when regulating roll 601 along with the t ₂ is located at the initial position, the sheet S ₂ is disposed in a state that closes the opening between the regulating roll 601 retracted moved lower compartment chute 23b Will be done. Therefore, the opening between the regulating roll 601 and the lower compartment chute 33b is from being sealed with the sheet S _2, many shredding sound by shredding mechanism 34 to the regulating roll 601 portion of the loading path 23 Therefore, there is little concern that the material will leak to the outside from the inlet 22 of the carry-in route 33.

-Calculation of the amount of shredded waste-
Further, since the retracted movement amount of the regulation roll 601 can be detected by the position detector 610, the thickness (number of sheets) of _{the paper S 2 can be determined from the detection result of the position detector 610.} Therefore, will be thick from the movement locus of the sheet S ₂ regulation roll 601 of the noise reduction mechanism 600 is calculated, also, the sheet S between the restriction roll 601 has detected the thickness of the sheet S ₂ The transit time of _{2 can be measured.}
It is possible to calculate the simultaneous shredding number of sheets S ₂ from the thickness and the transit time of the sheet S _2.
If the management center is notified of, for example, the number of shredders to be managed 30 in a certain day (for example, converted to the standard A4 size), the management center accumulates the number of shredders for a certain period. The total number of sheets can be calculated.
Therefore, it becomes possible to calculate the cumulative shredder amount of the shredder 30 to be managed, and thereby it is possible to determine whether or not the shredder waste collection work is necessary.

◎ Embodiment 5
23 (a) and 23 (b) show the main parts of the shredder management system according to the fifth embodiment.
In the figure, the shredder 30 mounts a paper bundle separator 620 near the loading port 32 of the shredder housing 31, and adjusts the number of paper bundles carried into the shredding mechanism 34 from the loading port 32 to a predetermined number or less. be.
In the present embodiment, the paper bundle separator 620 moves the shredded paper bundle S toward the insertion port 32 along the guide recess 31b of the shredder housing 31, and is the guide recess 31b. The separation plate 625 is installed substantially parallel to the guide surface.
The separation plate 625 of this example is, for example, a plate material made of the same material as the shredder housing 31, and is displaced toward the downstream side in the moving direction of the shredded paper bundle S with respect to the entrance of the guide surface of the guide recess 31b. At the end portion of the arranged and moving paper bundle S that comes into contact with the paper bundle S, there is a claw portion 626 that enters the paper bundle S and is formed so that the paper bundle can be separated.
In this example, one claw portion 626 is provided at substantially the center in the width direction intersecting the moving direction of the shredding paper bundle S, and the thickness direction dimension of the shredding paper bundle S is at the tip. It has a thin blade-shaped narrow portion 126a formed so as to have a sharp thin blade shape and the width direction dimension of the shredding paper bundle S narrows toward the tip end. The thin blade shape also includes a needle shape.
Further, the separation plate 625 has notches 127 which are gradually cut out in the moving direction of the shredding paper bundle S on both sides in the width direction with the claw portion 126 sandwiched.

Furthermore, the separation plate 625 is adapted to secure a space portion of a predetermined gap g between the guide surface of the guide recess 31b and the guide surface of the guide recess 31b for passing the separated paper bundle Sa up to the loading port 32. ..
Further, at the end of the separation plate 625 opposite to the claw portion 626, a storage receiver 630 for accommodating the remaining paper Sb other than the paper bundle Sa reaching the loading port 32 is integrally provided. In this example, the accommodating receiver 630 is provided as a recess in a portion adjacent to the guide recess 31b at the top of the shredder housing 31, so that the accommodating residual paper Sb does not fall into the accommodating receiver 630. A damming stopper (not shown) or a collection container (not shown) for receiving and collecting the dropped residual paper Sb is provided as needed.
A guard plate 640 is added above the separation plate 625 so as to cover at least the claw portion 126 (providing the thin blade-shaped narrow portion 126a) via a gap, so that the user does not directly touch the claw portion 626 of the separation plate 625. You may do so. Here, the gap between the guard plate 630 and the separation plate 625 may be set so that the remaining paper Sb other than the separated paper bundle Sa can enter.

Next, the operation of separating the shredded paper bundle in the shredder according to the present embodiment will be described.
Now, as shown in FIGS. 23 (a) and 23 (b), when an arbitrary number of sheets of _{paper for shredding S having a thickness t s} are moved toward the slot 32 along the guide surface of the guide recess 31b. , The tip of the paper bundle S abuts on the claw portion 626 of the separation plate 625.
In this state, the claw portion 626 of the separation plate 625 enters the separation position of the end portion of the paper bundle S. In particular, in this example, since the tip of the claw portion 626 is configured as a thin blade-shaped narrow portion 626a, it is easy to enter the separation position of the end portion of the paper bundle S.
After that, when the paper bundle S is further moved, as shown in FIG. 23 (b), the claw portion 626 of the separation plate 625 has a shape that narrows toward the tip, so that the paper bundle S is further moved. It enters between the paper bundles S from the separated position at the end of the paper bundle S and divides the paper bundle S into two. After that, the cutouts 627 formed on both sides of the claw portion 626 gradually widen the separation region of the paper bundle S by the claw portion 626 in the width direction of the paper bundle S to complete the separation of the paper bundle S. That is, of the paper stack S, the sheet bundle enters into the space portion of the gap g between the guiding surfaces of the guiding recesses 31b and the separating plate 625 Sa (thickness t _a in this _example) along the guide face It is guided to the input port 32. On the other hand, the paper bundle S that rides on the claw portion 626 of the separation plate 625 is stored in the storage receiver 630 as the _{remaining paper Sb (thickness t b in this example).}
In this state, the paper bundle Sa that has reached the loading port 32 reaches the shredding mechanism 34 via the carry-in route 33 and is subjected to the shredding process. _{At this time, since the paper bundle Sa reaching the shredding mechanism 34 is adjusted to a} predetermined thickness ta in consideration of the shredder 30's shredding performance (maximum number of simultaneous shredders), the shredding load by the shredder mechanism 34 Is effectively avoided.
Further, with respect to the remaining paper Sb stored in the storage receiver 630, the paper bundle S is separated by the paper bundle separator 620 again, and the paper bundle Sa having a predetermined thickness is provided to the shredding mechanism 34. do it.
In the present embodiment, the paper bundle separating tool 620 is provided in advance near the guide recess 31b of the shredder 30, but the present invention is not limited to this, and the paper bundle separating tool 620 is not limited to this, and the paper bundle separating tool 620 is provided near the input port 32 of the shredder 30. The tool 620 may be provided detachably.

-Calculation of the amount of shredded waste-
In the present embodiment, the paper bundle separator 620 separates the paper bundle S into an arbitrary number of paper bundles S or less into a predetermined number or less of the paper bundle Sa and feeds the paper bundles into the shredding mechanism 34 from the loading port 32. It becomes possible to do.
At this time, it is possible to measure the number of times each paper bundle Sa is loaded and the operating time of the shredding mechanism 34 when the paper bundle is loaded.
From this information, it is possible to calculate the number of sheets to be shredded by the managed shredder 30. If the management center is notified of, for example, the number of shredders to be managed 30 in a certain day (for example, converted to the standard A4 size), the management center accumulates the number of shredders for a certain period. The total number of sheets can be calculated.
Therefore, it becomes possible to calculate the cumulative shredder amount of the shredder 30 to be managed, and thereby it is possible to determine whether or not the shredder waste collection work is necessary.
Further, also in the present embodiment, billing processing is also performed based on the cumulative shredding amount.
In the case of this example, it cannot be said that the paper bundle Sa is always the specified number of sheets. Therefore, when calculating the cumulative shredding amount, the apparent cumulative shredding amount in which the specified number of paper bundles are inserted is used. It is preferable to make corrections such as multiplying the weighting coefficient.

◎ Example 1
This embodiment shows, for example, a management screen display example of the management device 100 used in the shredder shredder waste management system among the waste management systems according to the first embodiment.
FIG. 24 shows an example of a management screen display for managing the managed shredder of A Co., Ltd.
In the figure, the aircraft information of the managed shredder 30 is displayed in the upper area of the management screen. In addition, when the full level is set to 100%, the lower area of the management screen is color-coded by 20% (for example, red, orange, yellow, green, yellow-green) from the full level side. ing.
In addition, as the action judgment level, the amount of shredded waste accumulated is 85%, which requires same-day recovery, 70% is recovery preparation A, and 55% is recovery preparation B.
Then, in the right column, the estimated collection date based on the current situation is calculated and shown. Below the scheduled collection date, a "View past history" button is placed, and for the information on the deposit amount monitor, a "Confidential document deposit status" button and a "Shredded amount status" button are placed. Has been done.

Now, when the "shred amount status" button in FIG. 24 is pressed, as shown in FIG. 25, the current shred amount and the cumulative total for the current month are displayed as both graphs and numerical values.
In addition, when the "Confidential document accumulation status" button in FIG. 24 is pressed, as shown in FIG. 26, the daily change in the accumulation amount level of the current month is displayed in a bar graph, and the accumulation amount of shredded waste reaches 80%. It has been analyzed that the cycle is 8 days.
Further, when the "view past history" button in FIG. 24 is pressed, as shown in FIG. 27, the number of shredded sheets for each month in the past year is displayed as a bar graph, and the number of auto-reverses in each month is displayed. It is displayed.
With such a display example, it is possible to grasp the change in the accumulated amount of shredder dust of the shredder 30 to be managed in real time at predetermined intervals (for example, one day) at the management base.
In the billing process, the calculation may be performed based on the cumulative amount of shredded waste.

◎ Example 2
This embodiment shows a method for determining the amount of shredded waste used in the shredder shredded waste management system among the waste management systems according to the first embodiment.
In this example, it is generally known that when a plurality of shredded sheets are loaded into the shredding mechanism 34, the load current of the drive motor of the shredding mechanism 34 fluctuates according to the number of shredded sheets. A method is adopted in which an indicator such as an LED is used to perform a display such as changing the display color according to the load amount when shredding using the above. For example, in the management screen display example shown in FIG. 25, red, orange, yellow, green, and yellow-green are displayed in descending order of load.
Now, in the measurement circuit shown in FIG. 28 (a), the load current of the drive motor (induction motor is used in this example) is taken out by the extraction circuit by the rectifier diode and the operational amplifier, and the analog of the microcomputer (indicated by the microcomputer in the figure). When the current was taken from the port, the result shown in FIG. 28 (b) was obtained.
In FIG. 28B, it is understood that the load current of the drive motor fluctuates when the paper is loaded into the slot sensor. At this time, the analog level A is determined after the load current is sampled to make it uniform.

The changes in the load current for each shredded sheet are shown in FIGS. 29 (a) and 29 (b).
In the figure, FIG. 29 (a) shows an example of measurement data showing the relationship between the number of shredded sheets of Example 2 and the load current, and FIG. 29 (b) shows the number of shredded sheets of Example 2, the shredded speed, and the shredded time. This is an example of measurement data showing the relationship.
According to the figure, when the number of shredded sheets is small, the load current value is small and fluctuates depending on the shredded state. Therefore, an accurate number of sheets cannot be expected, but it is possible to grasp the minimum number of sheets.
Further, it is understood that the shredding speed tends to be high when the number of shredded sheets is small, and the shredding speed tends to be slow when the number of shredded sheets is large. However, since the fluctuation range is about 15%, it is considered that the contribution to the number of shredded sheets is small.
Therefore, it is possible to calculate the number of shredded sheets by the following calculation.
(1) In the case of 50Hz ・ One sheet when the current value 3.1A elapses about 40 seconds ・ 20 sheets when the current value 9.0A elapses about 5.0 seconds ・ About 20.0 seconds when the current value 9.0A elapses The elapsed time can be calculated from the relationship shown in FIGS. 29 (a) and 29 (b), as in the case of 80 sheets.
In addition, since there is a change in the current value when intermittently input or when the number of shredded sheets changes, it can be calculated by resetting at that time.
(2) Similarly, in the case of 60 Hz, it can be calculated from FIGS. 29 (a) and 29 (b).
(3) When the A4 plate, which is the standard size of paper, is loaded horizontally, the shredding time is shorter at the cost of increasing the load current value as compared with the vertical loading of the A4 plate, so there is no problem with the calculation method.
(4) In the case of thick paper or the like, it may be converted to the paper calculated here (for example, high-quality paper).
(5) Record the above data for a predetermined period each time it is shredded. In addition, it is possible to manage by notifying the management center of the daily number of shredded sheets through a communication line.
(6) The billing process is carried out based on the cumulative value of the number of shredded sheets.

◎ Example 3
FIGS. 30A and 30B show a method for determining the amount of shredded waste used in the shredder shredded waste management system among the waste management systems according to the first embodiment.
However, unlike the second embodiment, a case where an inverter motor is used as the drive motor is shown.
FIG. 30 (a) is an example of measurement data showing the relationship between the number of shredded sheets and the load current (50 Hz), and FIG. 30 (b) shows the relationship between the number of shredded sheets and the shredded speed and shredded time (50 Hz). This is an example of measurement data shown.
According to the figure, it was confirmed that even if the drive motor is an inverter motor, the number of shredded sheets can be calculated in the same manner as in the second embodiment.
It is also understood that the present embodiment can perform shredding processing up to a larger number of shredded sheets than the second embodiment.
