◎Outline of Embodiment FIG. 1 shows an outline of an embodiment of a waste disposal apparatus to which the present invention is applied and a waste management system using the same.
In the figure, the waste processing apparatus 1 has a shredding mechanism for shredding waste S to be discarded, and the shredded waste shredded by the shredding mechanism is stored in a waste container 2b. and a non-shredded waste processor 3 which processes unshredded waste S' to be discarded and stores it in a waste container 3b different from the waste container 2b of the shredded waste processor 2. , first recognition means 4 for recognizing object information for specifying the shredded waste processor 2 and the amount of shredded waste contained in the shredded waste container 2b of the shredded waste processor 2; non-shredded waste processing; second recognition means 5 for recognizing target information for specifying the device 3 and the amount of non-shredded waste contained in the waste container 3b of the non-shredded waste processor 3; and a communication means 6 for enabling communication of each information recognized by the recognition means 5 of 2 to a predetermined management base.

In such technical means, the shredded waste processor 2 shreds the shredded waste S to be discarded by the shredding mechanism 2c incorporated in the housing 2a, and takes the shredded waste into and out of the housing 2a. The shredded waste is received in a possible waste receptacle 2b. Here, as the shredding mechanism 2c, in the case of shredding highly confidential items, a shredding size that is extremely small to the extent that the shredding size cannot be reproduced is selected. In the case where the main object to be shredded is to have a low value, it is sufficient to select a shredded size that is larger than the minimum size.
On the other hand, the non-shredding processor 3 has a waste container 3b installed in a housing 3a, and treats the waste S' to be discarded in a non-shredded state and stores it in the waste container 3b. Here, as for the housing 3a of the non-shredding device 3, when highly confidential items are mainly discarded, the housing is larger than when low confidential items are mainly discarded. It is preferable to increase the security level by attaching a strict locking mechanism to the door for opening and closing the body 3a.

In addition, the first recognition means 4 identifies the shredded waste processor 2 to be managed by recognizing the target information and the amount of shredded waste, and performs shredding processing in the shredded waste processor 2. It is sufficient that the degree can be grasped at the management base. Further, the second recognition means 5 identifies the non-shredded waste processor 3 to be managed by recognizing the target information and the amount of non-shredded waste, and disposes in the non-shredded waste processor 3. It is sufficient that the degree of processing can be grasped at the management base.
Further, the communication means 6 only needs to have a function of communicating each information recognized by the first recognition means 4 and the second recognition means 5 with the management base. It may be provided separately, or may be shared for both.
In this example, two systems of waste processors (shredded waste processor 2 and non-shredded waste processor 3) are selectively used according to the degree of airtightness of the scraps S and S' to be discarded. It is possible to manage the amount of waste contained in the waste containers 2b and 2c.

Next, a representative aspect of the waste processing apparatus according to this embodiment will be described.
First, as a representative mode of the waste processing apparatus 1, the shredded waste processing device 2 and the non-shredded waste processing device 3 are provided with respective waste containers 2b and 3b in different housings 2a and 3a. mentioned. This example is a mode in which the existing shredded waste processor 2 and non-shredded waste processor 3 are used, and the respective waste amounts can be managed.
Further, as another representative aspect of the waste processing device 1, the shredded waste processing device 2 and the non-shredded waste processing device 3 have a common housing 2a (or 3a), and the common housing 2a (or 3a) can be exemplified by installing the respective waste containers 2b and 3b in the respective partitioned areas. This example is a mode in which the processors 2 and 3 are incorporated in a common housing 2a (or 3a).
Furthermore, as a representative aspect of the first and second recognition means 4 and 5, at least one of them is a detector capable of continuously detecting the amount of waste contained in the corresponding waste container 2b (or 3b). (not shown). This example includes a detector that continuously detects the amount of waste contained in the waste container 2b (or 3b). Any suitable method may be selected, including a detection method and a weight detection method.

In addition, as a representative aspect of the first recognition means 4, it includes an operation condition recognition means that recognizes the operation condition of the shredding mechanism 2c in the shredded waste processor 2 in an updatable manner, and the operation condition recognition means One that recognizes the amount of shreds is included. In this example, the amount of scraps contained in the scrap container 2b is indirectly recognized from the operation status of the shredding mechanism 2c of the shredded scrap processor 2. FIG.
Furthermore, as a typical mode of use of the two-system processors 2 and 3, the shredded waste processor 2 has a shredder mechanism 2c whose shredded size is an extremely small size that cannot be reproduced. While the mechanism 2c shreds highly confidential scraps S to be discarded, the non-shredded scrap processor 3 leaves the less confidential scraps S' to be discarded unshredded. A processing mode can be mentioned. In this example, among the scraps S and S' to be discarded, the shredded waste processor 2 processes the highly confidential waste S and the non-shredder 3 processes the low confidential waste S'. be.
As another representative mode of use of the two systems of processors 2 and 3, the shredded waste processor 2 has a shredder mechanism 2 with a coarser size than the extremely small size of which the shredded waste size cannot be reproduced. The shredding mechanism 2c shreds less confidential wastes S to be discarded, while the non-shredded waste processor 3 has a waste container 3b which is strictly controlled to open and close. Among the scraps S′ to be scraped, there is an aspect in which those with high confidentiality are treated without being shredded. In this example, among the wastes S and S' to be discarded, the shredded waste processor 2 treats the low-confidential waste S and the non-shredder 3 treats the high-confidential waste S'. be.

Moreover, it is possible to construct a waste management system using the waste processing apparatus 1 described above.
In this example, as shown in FIG. 1, the waste management system is provided in the above-described waste processing apparatus 1 and the above-described management base. a management device 10 for managing the amount of waste contained in each of the waste containers 2b and 3b of No. 3, the management device 10 having communication means 11 for enabling communication with the waste processing device 1; collecting means 12 for collecting waste information contained in the waste containers 2b, 3b of the respective processors 2, 3 of the waste processing apparatus 1 based on the target information and the waste amount information transmitted from the apparatus 1; Determination means 13 for determining whether or not the wastes contained in the waste containers 2b, 3b of the processors 2, 3 need to be collected based on the waste information collected in the waste processing apparatus 1 by the determination means 13. and an instruction means 14 for instructing the operation of collecting the waste under the condition that it is determined that the waste needs to be collected. In addition, in FIG. 1, X is a network.

In such technical means, the management device 10 may include the communication means 11, the collection means 12, the determination means 13, and the instruction means 14. However, in embodying each function, a microcomputer (display with a display) can be used communicatively.
Further, as a representative aspect of the determination means 13, when it is determined whether or not the wastes contained in the waste containers 2b and 3b of the processors 2 and 3 need to be collected, A mode of predicting the expected date of collection from the change in the amount of waste that has been processed is exemplified. In this example, the scheduled collection date is predicted from the change in the amount of scraps when determining whether or not collection of scraps is necessary by the determination means 13. In addition to the scheduled collection date, there is a The preparation date (for example, a date appropriately selected from y% of the cumulative amount of waste on the scheduled collection date <percentage of, for example, 60% to 80%>) may be predicted.
Further, as a representative mode of the instruction means 14, a collection base suitable for the waste processing apparatus 1 is selected, and the waste collection work is instructed to the selected collection base. In this example, based on the place where the waste processing apparatus 1 is installed, a collection base suitable for collecting the waste is selected, and the collection base is instructed to perform the waste collection work. Here, if, for example, the collection worker W is provided with the individual terminal 15 at the collection site, the instruction information from the instruction means 14 of the management device 10 is transmitted to the individual terminal 15 via the network X. Then, the recovery worker W can acquire instruction information (collection work information such as the object to be collected, the amount of waste to be collected, and the delivery destination of the collected waste), and can carry out the waste collection work.
Further, the individual terminal 15 is provided for each collection site, and may communicate directly with the management site or may communicate indirectly via an intermediate server. In this example, there are both mobile and fixed collection bases. The mobile collection base assumes, for example, that the collection worker W has a portable individual terminal 15, and the fixed collection base is a stationary collection base. Assuming the individual terminal 15, the instruction is given to the collection worker W belonging to the collection base.

Further, as a preferred aspect of the management device 10, the discriminating means 13 is accommodated in the scrap container 2b or 3b of either the shredded scrap processor 2 or the non-shredded scrap processor 3 of the scrap processor 1. An example is a mode having temporary stop means (not shown) for temporarily stopping the processing by the processor 2 or 3 that needs to collect the waste when it is determined that the waste needs to be collected. be done. In this example, when either one of the processors 2 or 3 becomes full, for example, and it becomes necessary to collect the waste contained in the waste container 2b or 3b, the processor 2b or 3b is continuously operated. If the disposal is made possible, there is a concern that the waste may overflow from the waste container 2b or 3b. Therefore, in this example, the use of the other processor 3 or 2 is encouraged by temporarily stopping the treatment by the processor 2 or 3 that requires waste collection.
Here, for example, when the shredded waste processor 2 requires waste collection, for example, full display and prohibition of driving of the shredding mechanism 2c are performed, while the non-shredded waste processor 3 requires waste collection. In such a case, for example, the full display and the trash inlet may be closed with a shutter or the like.

It is the sum of the number of times that the above overload state occurred.

(J-7) Number of auto-reverse operations Auto-reverse processing prevents paper jams in the shredding mechanism 35 when paper S with a high load exceeding the shredding capacity is fed to the shredding mechanism 35. For this purpose, by rotating the drive motor 51 in reverse, the inserted paper S is returned and discharged from the inlet 32. For example, the number of reverse rotations of the drive motor 51 during operation of the shredding mechanism 35 can be counted. be done.
(J-8) Number of Heat Dissipation Times An overheat protector (not shown) is attached to the drive motor 51, and the number of times the overheat protector operates is counted.
(J-9) Number of Detections of Waste Full Sensor The waste full sensor 82 detects when the volume of the shredded waste Sa in the waste container 37 reaches a certain full level.

(J-SR) Usage History Information In this example, the accumulated shredding amount of the paper S when the shredding process by the shredding mechanism 35 is repeatedly performed is used. The accumulated shredded amount is obtained by accumulating the shredded amount calculated by the following formula.
Cumulative shredding amount = Σ (operating time x shredding load)
Here, the 'operating time' refers to the normal operating time for each shredding process by the shredding mechanism 35, and the 'shredding load' is the load during the shredding process by the shredding mechanism 35, specifically the driving motor 51. It corresponds to the number of sheets to be shredded at the same time, which corresponds to the driving current ratio. That is, assuming that the shredding process by the shredding mechanism 35 can shred a plurality of sheets of paper S at the same time, as shown in FIG. It increases proportionally with an increase in the number of shredded sheets). At this time, the difference between the drive current I (1) when the number of shredded sheets is 1 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 (integer of ) sheets, and the difference between the drive current I(n) at the time of no load and the drive current I(0) at no load is ΔI(n). 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.

Further, the drive current I of the drive motor 51 shows If as shown in FIG. It shows a tendency to increase as Ia, Ib, and Ic (If<Ia<Ib<Ic) as the weight increases (for example, 1t to 3t).
This is because, as the shredding mechanism 35 is used over time, the cutter element of the shredding mechanism 35 may be jammed with paper dust or shredded waste, or the cutter element may wear out, which is accompanied by 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 the no-load operation of the drive motor 51 is periodically or irregularly monitored, the degree of deterioration of the cutter element of the shredding mechanism 35 (paper clogging, wear) can be grasped.
Furthermore, considering that the drive current I during the shredding process by the shredding mechanism 35 also changes with the deterioration of the shredding mechanism 35, the driving current I measured based on the degree of deterioration of the shredding mechanism 35 is considered. If the current I is corrected, the shredding load in each shredding process can be calculated more accurately, which is preferable in that the cumulative amount of shredding can be calculated more accurately.

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

－Basic structure of collection box－
In this embodiment, as shown in FIG. 2, in addition to the shredder 30, the management target of the customer U includes a collection box 500 (for example, 500a). It is designed to be discarded as it is without shredding.
In this example, as shown in FIG. 6(a), the collection box 500 has an inlet 502 for throwing in waste scraps S' in a part of the box body 501, for example, the upper wall. A door 503 with a key is provided on one side so that it can be opened and closed.
The box main body 501 contains a waste container 510 in which waste waste S′ is stored. It has become.
A collection box 500 (for example, 500a) is provided with a waste amount sensor 520 for detecting the volume of waste waste S' contained in the waste container 510. Object information for specifying the collection box 500 and the waste amount sensor 520 is connected to the network X via, for example, a modem 75, and can communicate with the management device 100 of the manager M/management center.

In this example, as shown in FIGS. 6A and 6B, the waste amount sensor 520 is mounted, for example, on a part of the inner wall of the box body 501 afterward. A control device (not shown) for controlling processing and communication processing by the communication unit (modem 75) is provided in the box main body 501. FIG.
Here, the waste amount sensor 520 is composed of, for example, an optical distance sensor including a light-emitting element and a light-receiving element. Then, by detecting the output level of the reflected light with the light receiving element, the waste quantity level of the waste waste S' is determined.
Machine information of the recovery box 500 and the like are written in the memory of the control device (not shown). will be sent as appropriate to
Furthermore, although one scrap amount sensor 520 is used in this embodiment as well, a plurality of scrap amount sensors are installed and the outputs of these scrap amount sensors are averaged to detect the scrap amount level. good too.
In the present embodiment, the waste amount sensor 520 is composed of an optical distance sensor, but is not limited to this. For example, as shown in FIG. Needless to say, a waste amount sensor 530 for detecting the weight of the waste container 510 to be accommodated may be employed.

-Management device-
In this embodiment, as shown in FIG. 7, the management device 100 is communicably connected to the network X via the communication modem 110, and the management server 120 accessible by the collection worker W through the portable 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 operating status information) of the managed shredders 30 is stored in an updatable manner. The customer database 130 can be browsed.
In particular, in this example, the management device 100 diagnoses whether or not collection work is necessary for the shredded scraps Sa shredded and discarded by the managed shredder 30 based on the customer database 130, and when collection work is required, , a work diagnosis unit 140 capable of selecting a collection worker W and creating a shredded waste collection work instruction 141 for the selected collection worker W. FIG.
In this example, the management device 100 is adapted to execute waste management processing as shown in FIG. 9, for example.
Then, the recovery worker W refers to the recovery work instruction 141 transmitted from the management device 100 to the portable terminal 200, goes to the customer U, and performs the recovery work of the shredded waste Sa generated from the shredder 30 to be managed. are to be implemented.

<Customer database>
The customer database 130 used in this example is shown in FIG. 8(b).
In the figure, a customer database 130 includes user information 131, machine information 132, operating status information 133, usage history/error history and other information 134, and update processing is performed each time information is received from the managed shredder 30. It is designed to be done.
Here, the user information 131 includes, for example, company name, address, person in charge, contact information, and delivery date. The normal operation time, the number of times of normal operation … the number of times of detection by various sensors, etc., and the usage history / error history and other information 134 include the cumulative amount of shredding (for example, a predetermined value), various error codes and Display of the time of occurrence, and transmission request conditions when the manager M side periodically requests the managed shredder 30 to transmit are included.
In this example, as one of the operating status information 133, in order to diagnose the degree of deterioration of the cutter element of the shredding mechanism 35, the drive current value during no-load operation of the drive motor 51 is periodically changed from the initial operation. Alternatively, it is irregularly measured and stored, which is also stored in the customer database 130 .

－Operating process of scrap management system－
Next, the operation process of the waste management system according to this embodiment will be described.
As shown in FIG. 9, the management device 100 periodically or irregularly performs an operation of selecting a management target at a predetermined time (for example, when the waste amount level reaches a predetermined level). .
Now, assuming that the time has come to select the shredder 30, for example, the shredder 30 is selected as an object to be managed, and the shredder communication control process and the shredder management process are carried out.
On the other hand, assuming that the time to select the collection box 500 has arrived, the collection box 500 is selected as a management target, and the collection box communication control process and the collection box management process are performed.
Here, shredder communication control processing and shredder management processing will be described as examples.

－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 has been performed by the shredding mechanism 35, and if the shredding process has been performed, checks the shredding execution conditions. For example, the normal operation time, the number of normal operations, the drive current of the drive motor 51, etc. are checked, and various machine information accompanying the shredding process (overload operation time, overload operation number, auto reverse number, heat dissipation number, various sensor number of detections, etc.).
Then, the amount of shredding by the shredding mechanism 35 is calculated based on the shredding execution conditions described above, and the cumulative amount of shredding is calculated by accumulating the amount of shredding so far.
After that, the control device 70 checks whether or not the calculated accumulated shredded amount has reached a predetermined specified value, and when it reaches the specified value, the time for transmitting the information to the manager M is reached. 8A), and transmits the necessary information to the manager M (see FIG. 8A).
In addition, in the information transmission process, it is preferable to perform preprocessing (password confirmation, etc.) for ensuring security with the communication destination.
Furthermore, when the control device 70 determines that the transmission time has not been reached based on the cumulative amount of shredding, it checks whether there is a warning notification or whether there is a transmission request from the manager M. After that, if there is no request, the information transmission processing is not executed, and if there is any request, the necessary information is transmitted to the manager M according to the request.
Here, the 'warning notification' is to notify a warning that there is a high probability that the managed shredder 30 will be hindered in continuing normal operation. When the number of times of detection reaches a predetermined threshold value k times, the shredded waste Sa is full and it becomes difficult to continue the shredding process by the shredding mechanism 35. be.

- Processing on the management device side -
The management device 100 executes a shredder management program shown in FIG. 11, for example.
In the figure, the management device 100 determines whether or not to send a transmission request 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 manager M side, a transmission request is made to the managed shredder 30 .
On the other hand, if there is no transmission request from the manager M side as 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, the managed object A transmission request is made to the shredder 30, and if there is no request from the collection worker W, it is constantly monitored whether or not it is received from the managed shredder 30, and if it is received from the managed shredder 30, the reception is acknowledged. To give permission.
Thereafter, the management device 100 reads the information transmitted from the managed shredder 30 and updates the customer database 130 of the management server 120, as shown in FIG.
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 collection work is necessary, a collection work instruction 141 to be sent to the collection worker W is generated. create.

Here, the details of the processing performed by the work diagnosis unit 140 are as follows.
(1) Determining whether collection is necessary or not This step determines whether or not the shredded waste Sa generated from the managed shredder 30 needs to be collected based on the shredded waste information of the managed shredder 30 in the customer database 130. In this example, for example, as shown in FIG. 12, the cumulative amount of shredding is T, and the specified value requiring collection work of the shredded waste Sa (for example, the waste container 37 is full at the request of the customer U). If T1 is a specified value that can be selected in advance as an integral multiple of the amount that has been cut, it will be determined that collection of the shredded waste Sa is necessary under the condition that T=T1.
In this example, when the information on the cumulative shredded amount T1 as the shredded waste information is used as the collection operation information for the shredded waste Sa, the cumulative shredded amount T1 in the customer database 130 is reset, and the cumulative shredded amount T1 is reset. The cumulative calculation of the weight T1 is restarted.
(2) Collection operator W selection process Under the condition that it is determined that the shredder 30 to be managed needs to collect the shredded scraps Sa in the judgment process, the collection operator W suitable for the shredder 30 to be managed is selected.
At this time, a preferred method for selecting the collection worker W is, for example, in a mode in which the mobile terminal 200 has a GPS function, the GPS function is used to select the collection worker W as a collection base from the position of the mobile terminal 200. Since it is possible to grasp the current position of , it is possible to select one or a plurality of collection sites near the managed shredder 30, which is the collection destination, as a selection candidate, and finally select the collection worker W who will be in charge. .
(3) Recovery work instruction creation process When the recovery operator W for the managed shredder 30 is selected, the recovery work instruction 141 to be sent to the selected recovery operator W is created.
Here, as the description contents of the collection work instruction sheet 141, information necessary for the collection worker W to visit the location of the customer U of the shredder 30 to be managed and to carry out the collection work of the shredded waste Sa is described. You can do it like this.
For example:
- location of customer U - machine information of shredder 30 to be managed - collection amount of shredder Sa - delivery destination of collected shredder Sa Since the shredded size is grasped, for example, as a delivery destination, taking into account the one that reuses and recycles the shredded waste Sa, the manager M determines the shredded size and the collection amount of the shredded waste Sa. do.

-Processing by the recovery worker W side-
When collection worker W acquires collection work instruction sheet 141 sent to mobile terminal 200 from manager M, collection worker W transmits an acceptance notification from mobile terminal 200 to management device 100 when accepting the job.
Thereafter, after confirming the availability of the visit to the customer U of the shredder 30 to be managed, the collection worker W goes to the customer U and collects the shredder Sa from the shredder 30 to be managed.
At this time, as shown in FIG. 7, since the shredded waste Sa generated from the shredder 30 to be managed is stored in, for example, a waste bag 90, the collecting worker W puts the collection source information in the waste bag 90. , a waste collection label 91 on which shredded waste information (for example, shredded size, collected amount of shredded waste, etc.) and delivery destination information are described, is attached, and the waste bag 90 is collected. Hand over the completion document of collection work of shredded waste Sa.
It is preferable that the waste collection label 91 is prepared in advance so that it can be attached together with the collection work instruction sheet 141, for example.
In this state, the collection worker W transmits a collection completion notice 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 by the collection worker W. FIG. Then, the collecting worker W carries the collected shredded waste Sa directly or via another person in charge to the receiving destination.

- Overview of shredded waste management in Embodiment 1 -
FIG. 13 schematically shows the mutual relationship among 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 (machine information/operating status information) from the managed shredder 30 owned by the customer U.
(2) The manager M issues a recovery operation instruction to the recovery worker W when the recovery operation conditions for the shredded waste Sa are ready.
(3) The collection worker W collects the shredder Sa generated from the shredder 30 to be managed by the customer U.
(4) The collecting operator W carries the collected shreds Sa to the destination (recycling company Q).

-Outline of maintenance/repair management in the first embodiment-
In this embodiment, the management device 100 collects machine information and operating status information of the shredder 30 to be managed, so in addition to managing shredders 30 described above, maintenance and repair management of the shredder 30 to be managed is also performed.

Next, the principle of operation of the waste amount sensor 410 will be described.
Now, as shown in FIG. 20(a), as the capacity of the shredded waste Sa accommodated in the waste container 37 gradually increases, the surface position of the shredded waste Sa changes from _d6 to _d5 in the drawing. It increases in order of d ₄ →d ₃ →d ₂ →d ₁ . _At this time, if the installation position of the waste amount sensor 410 is d0, the distance d from the waste amount sensor ₄₁₀ to the shredded waste Sa is _d6 > _d5 > _d4 > _d3 >d2> _d1 . is. In this example, it is assumed that the surface position d1 of the shredded waste Sa is the _full level of the shredded waste Sa.
In this state, after the irradiation light Bm from the light emitting element 411 is reflected on the surface of the shredded waste Sa, the output level of the reflected light Bm reaching the light receiving element 412 is as shown in FIG. The longer the optical path length from the light emitting element 411 to the light receiving element 412 of the sensor 410 is, the lower the value becomes, and the shorter the optical path length is, the _more the Vmax is shown at the position d1.
In this example, as shown in FIG. 20(c), 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) at a predetermined detection cycle. The output of the light-receiving element 412 (point A in FIG. 19B) is detected, sampled at predetermined sampling intervals, and averaged, for example, to obtain the output value of the waste amount sensor 410 . The reason for such averaging processing is that the output of the light receiving element 412 fluctuates during the shredding processing of the shredder. Note that the sampling method is not necessarily limited to averaging, and may be selected as appropriate, such as averaging excluding the maximum and minimum values.

Further, in this example, the control device 420 stores a characteristic graph (FIG. 20(b)) of the output of the waste amount sensor 410 (the output of the light receiving element 412) in a memory (not shown), First, the output of the scrap amount sensor 410 is detected, information on the corresponding distance d from the scrap amount sensor 410 to the shredded scrap Sa (for example, 16 levels of scrap amount levels) is calculated, and transmitted via the communication unit 421. do.
For example, the following information is written in the memory of the control device 420 as machine information of the shredder 30 to be managed and information on the power supply of the waste amount communication device 400, and is transmitted together with the above-described 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 this embodiment will be described.
In the present embodiment, the waste amount communication device 400 operates differently depending on whether the external power supply 431 is used or the internal power supply (battery) 430 is used.
－In case of external power supply－
As shown in FIG. 21(a), the detection operation by the dust amount sensor 410 to which electric power is supplied from the external power supply 431 is continuously performed, and the control device 420 determines the amount level of the dust amount detected by the dust amount sensor 410. If there is a level change, the waste amount level information is transmitted at short fixed time intervals t ₁ (for example, 10 seconds). On the other hand, when there is no level change for 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. 21(b), when using an internal power supply (battery) 430, control is required to suppress consumption of the internal power supply 430. FIG. In addition, in FIG.21(b), the location shown by B shows the area|region enclosed by B of Fig.21 (a).
First, it checks whether the internal power supply 430 has a low voltage or not, and if it detects that it has a low voltage, it transmits battery replacement information every predetermined time t ₃ (for example, one hour). .
On the other hand, when the internal power supply 430 is not at a low voltage, a scrap amount level determination is performed, and the scrap amount of the shredded scrap Sa contained in the scrap container 37 is at a predetermined level (for example, the surface position of the shredded scrap Sa). is equal to or higher than the output level (Vth) of the waste amount sensor 410 at _d6 .
At this time, when the output level of the waste amount sensor 410 is less than Vth, the waste amount level determination interval 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. During this judgment interval t4, one _second is sampled 10 times, and an averaging process is performed in order to equalize the level fluctuation of the amount of waste. Processing other than the averaging processing, such as using the minimum value or the maximum value, is also possible.
When the output level of the scrap amount sensor 410 is Vth or higher, the surface position of the _shredded scrap Sa is positioned at _d6 or higher. (for example, 10 seconds), and the waste amount level information is transmitted at a transmission interval of t ₇ (t ₇ =t ₆ in this example).
If there is no change in the scrap amount level detected by the scrap amount sensor 410 for 30 seconds, the scrap amount level information is transmitted every predetermined time t ₂ (for example, one hour). However, if the waste amount level determination interval is _{t 4} (for example, 1 minute), the waste amount level will 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 determines the amount of waste together with the machine information of the managed shredder 30 and the power information of the waste amount communication device 400. Quantity level information is sent to the management device 100 .
As a result, the manager M/management center grasps the change in the amount of shredded scrap Sa accommodated in the shredder 37 of the managed shredder 30, and when the scrap amount level reaches the full level, the recovery operator In addition, when the scrap amount communication device 400 requires maintenance work such as battery replacement, the maintenance/repair personnel P instructs maintenance work, and each work is performed. It can be implemented quickly.

In the present embodiment, the waste amount communication device 400 is mounted on the opening edge of the waste container 37 afterward, but is not limited to this, and may be mounted on the inner wall of the shredder housing 31 afterward. may Also, 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 aspect, even if the distribution of the shredded waste Sa contained in the waste container 37 is uneven, by averaging the outputs of the plurality of waste quantity sensors, compared to the case of one waste quantity sensor, It is possible to detect a more accurate waste amount level.

Although an optical distance sensor is used as the scrap amount sensor 410 in this embodiment, the present invention is not limited to this. (not shown) may be used.
In the case of this example, the weight of the waste container 37 is measured, the amount corresponding to the weight is recorded each time, and the cumulative amount of shredded material is grasped in a predetermined period.
As a more specific processing example,
(1) Record at a fixed time every day for a certain period of time. It also notifies the management center of the weight of the day and manages it.
(2) Record when the specified weight is reached. It also notifies the management center of the weight of the day and manages it.
(3) Managed by a combination of (1) and (2) above.
(4) Even if the waste bag is replaced once it becomes full, the replacement can be grasped because the weight information is recorded. Also, even if the waste bag is replaced before it becomes full, the weight before and after the replacement is recorded, so that the replacement can be grasped.
(5) In the case of notification to the management center, it becomes possible to take action to collect waste before it becomes full according to the contents of the notification information, and it is possible to concentrate on the work without interrupting the user's work. Become.

◎Embodiment 4
FIG. 22 shows the main part of the shredder shredded waste management system according to the fourth embodiment.
-Structure of noise reduction mechanism-
In the present embodiment, as shown in FIG. 22, a noise reduction mechanism 600 is provided in the middle of the carry-in path 33 that inclines obliquely downward in the shredder housing 31 . moves according to the thickness of the paper S to be fed, the thickness (number of sheets) of the paper S to be fed is calculated from the amount of movement of the regulation roll 601, and the accumulated value of the amount of shredded waste of 30 of the shredder It is intended to calculate
In this example, as shown in FIGS. 22 and 23 (a) and (b), the noise reduction mechanism 600 is provided in a part of the upper partition chute 33a that partitions the upper side of the carry-in path 33. A long rectangular attachment hole 602 extending along the width direction is provided, and a regulating roll 601 is installed in a portion facing the attachment hole 602 so as to face the lower division chute 23b.
In this example, the lower section chutes 33b are provided on both sides in the width direction of the flat plate-like chute main body as protrusions that protrude toward both ends in the axial direction (longitudinal direction) of the regulating roll 601 with steps. The regulating roll 601 is provided with a stepped portion 603 protruding from the bottom of the lower section chute 33b. The opening of the gap g is secured between the . Note that the gap g is selected to be about 0.1 mm (0.08 to 0.12 mm), assuming a dimension through which one sheet of paper S having a basis weight of about 60 to 100 g can pass.
Further, a guide plate 605 for guiding the movement trajectory of the regulation roll 601 along one longitudinal side edge of the mounting hole 602 of the upper partition chute 33a is inclined at a predetermined angle (for example, 20 to 50°) with respect to the horizontal direction. By placing the regulating roll 601 on the guide plate 605, the regulating roll 601 is arranged facing the mounting hole 602, and both ends of the regulating roll 601 in the axial direction are arranged at the stepped portions 603 of the lower compartment chute 33b. has come to be supported.

- Operation of the noise reduction mechanism -
Next, the operation of noise reduction mechanism 600 used in this embodiment will be described.
First, as shown in FIG. 23(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), When the sheet S1 is carried into the carry _- in path 33 from the inlet 32, the regulating roll 601 is arranged with the lower section chute 33b of the carry-in path 33 as an opposing member to secure a gap g. This gap g is narrower than the opening width of the paper S1 in the thickness direction of the carry _{-in path 33, but is set larger than the thickness t1 of one sheet of} paper S1. ₁ passes through the opening of the gap g between the regulating roll 601 and the chute body of the lower compartment chute 33b and reaches the shredding mechanism . At this time, the opening of the gap g between the regulating roll 601 and the chute body of the lower compartment chute 33b leaves only _{a small gap |gt 1 |} Shredded sound is greatly attenuated in minute gaps.
Also, as shown in FIG. 23( _b ), when the objects to be shredded are a plurality of sheets S ₍ specifically, S2) having a thickness t2 equal to or greater _than the gap g, the sheets S2 are When passing through the opening of the gap g of the regulating roll 601, the regulating roll 601 is carried in toward the shredding mechanism 34 along the lower section chute 33b of the carry-in path 33 while the regulating roll 601 is retracted.
In this example, since the regulating roll 601 moves in the retreating direction as the sheet S2 having _high surface rigidity passes, the width of the opening between the regulating roll 601 and the _lower compartment chute 33b is the thickness of the sheet S2. _Along with t2, the gap g is expanded from the size of the gap g when the regulation roll 601 is positioned at the initial position, and the sheet S2 is arranged in a state in which the opening between the retracted regulation roll 601 and the _lower section chute 23b is closed. be done. Therefore, since the opening between the regulating roll 601 and the _lower compartment chute 33b is sealed with the paper S2, most of the shredding noise by the shredding mechanism 34 is transmitted to the regulating roll 601 portion of the carry-in path 23. Therefore, there is little concern of leakage to the outside from the inlet 22 of the carry-in route 33.

- Calculation of the amount of shredded waste -
Further, since the retraction movement amount of the regulation roll 601 can be detected by the position detector 610, the thickness (the number of sheets) of the sheet S2 can be determined from the detection result of the position detector 610. _FIG . Therefore, the thickness of the sheet _S2 is calculated from the locus of movement of the regulation roll 601 of the noise reduction mechanism 600, and the thickness of the sheet S2 is detected while the regulation roll 601 is detecting the thickness of the sheet _S2 . ₂ transit time can be measured.
It is possible to calculate the simultaneous shredding _number of sheets S2 from the thickness of the sheets S2 and the passing _time .
If the management center is notified of, for example, the shredded number of shredders 30 to be managed in a given day (e.g., converted to standard A4 size), the management center accumulates the number of shredded sheets for a certain period of time. The total number of sheets can be calculated.
Therefore, it is possible to calculate the cumulative shredding amount of the shredder 30 to be managed, and thereby to determine whether or not to collect the shredded waste.

◎Embodiment 5
24(a) and 24(b) show the main part of the shredder shredded waste management system according to the fifth embodiment.
In the figure, the shredder 30 has a stack separator 620 mounted near the input port 32 of the shredder housing 31, and adjusts the number of sheets of the stack of sheets carried into the shredding mechanism 34 from the input port 32 to a predetermined number or less. be.
In this embodiment, the sheet bundle separator 620 moves the shredded sheet bundle S toward the inlet 32 along the guiding recess 31b of the shredder housing 31. A separation plate 625 is installed substantially parallel to the guide surface.
The separation plate 625 of this example is a plate member made of the same material as the shredder housing 31, for example, and is offset to the downstream side in the moving direction of the shredding sheet bundle S with respect to the entrance of the guide surface of the guide recess 31b. At the end portion which is arranged and abuts against the moving sheet bundle S, there is a claw portion 626 which is formed so as to be able to enter the sheet bundle S and separate the sheet bundle.
In this example, one claw portion 626 is provided substantially in the center of the width direction that intersects the moving direction of the sheet bundle S for shredding, and the dimension in the thickness direction of the sheet bundle S for shredding is at the tip. It has a thin blade-like narrow width portion 126a which is formed in the shape of a thin blade sharpened toward the front, and which is formed so that the width direction dimension of the sheet bundle S for shredding narrows toward the tip. Note that the thin blade shape includes a needle shape.
Furthermore, the separation plate 625 has notches 127 that are gradually cut away in the moving direction of the sheet bundle S for shredding on both sides in the width direction with the claws 126 interposed therebetween.

Furthermore, the separation plate 625 secures a space of a predetermined gap g between the guide surface of the guide recess 31b and the sheet bundle Sa separated up to the inlet 32 to pass therethrough. .
Further, at the end of the separation plate 625 opposite to the claw portion 626 , an accommodation receiver 630 is integrally provided for accommodating the remaining sheets Sb other than the sheet bundle Sa reaching the inlet 32 . In this example, the accommodation receiver 630 is provided as a recess at a portion adjacent to the guide recess 31b at the top of the shredder housing 31. The accommodation receiver 630 is designed to prevent the remaining sheets Sb from falling. A damming stopper (not shown) or a recovery container (not shown) for receiving and recovering the dropped remaining sheets Sb is provided as required.
In addition, a guard plate 640 is added above the separation plate 625 with a gap therebetween so as to cover at least the claw portion 126 (having the thin blade-shaped narrow portion 126a), 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 to such an extent that the remaining sheets Sb other than the separated sheet bundle Sa can enter.

Next, the separation operation of the bundle of sheets for shredding in the shredder according to the present embodiment will be described.
Now, as shown in FIGS. 24(a) and 24(b), when an arbitrary number of sheet bundles _S having a thickness ts for shredding are moved along the guide surface of the guide recess 31b toward the inlet 32, , the leading edge of the stack of sheets S hits 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 at the end of the stack of sheets S. As shown in FIG. In particular, in this example, since the tip of the claw portion 626 is formed as a thin blade-shaped narrow portion 626a, it is easy to enter the separation position of the end portion of the sheet bundle S.
After that, when the stack of sheets S is further moved, as shown in FIG. enters between the sheet stack S from the separation position at the end of the sheet stack S, and divides the sheet stack S into two. After that, the notch portions 627 formed on both sides of the claw portion 626 gradually widen the separation area of the sheet bundle S by the claw portion 626 in the width direction of the sheet bundle S, and the separation of the sheet bundle S is completed. That is, the sheet bundle Sa (thickness t _a in this example) that has entered the gap g between the separating plate 625 and the guide surface of the guiding recess 31b of the sheet bundle S is slid along the guide surface. It is led to the input port 32 . On the other hand, the stack of sheets S that has run on the claw portion 626 of the separation plate 625 is accommodated in the accommodation receiver 630 as the remaining sheets Sb (thickness t _b in this example).
In this state, the sheet bundle Sa that has reached the inlet 32 passes through the carry-in path 33 and reaches the shredding mechanism 34, where it is shredded. At this time, the sheet bundle Sa reaching the shredding mechanism 34 is adjusted to have _a predetermined thickness ta in consideration of the shredding performance of the shredder 30 (maximum number of sheets to be shredded simultaneously). is effectively avoided.
Further, the remaining sheets Sb accommodated in the accommodation receiver 630 are again separated by the sheet bundle separator 620, and the sheet bundle Sa having a predetermined thickness is supplied to the shredding mechanism 34. Just do it.
In the present embodiment, the sheet bundle separation tool 620 is provided in advance near the guiding recess 31b of the shredder 30, but is not limited to this. You may make it provide the tool 620 so that attachment or detachment is possible.

- Calculation of the amount of shredded waste -
In this embodiment, the sheet bundle separator 620 separates an arbitrary number of sheet bundles S into sheet bundles Sa having a predetermined number of sheets or less and throws them into the shredding mechanism 34 from the inlet 32 . it becomes possible to
At this time, it is possible to measure the number of times each sheet bundle Sa is inserted and the operation time of the shredding mechanism 34 when the sheet bundle is inserted.
From these pieces of 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 shredded number of shredders 30 to be managed in one day (e.g., converted to standard A4 size), the management center accumulates the number of shredded sheets for a certain period. The total number of sheets can be calculated.
Therefore, it is possible to calculate the cumulative shredding amount of the shredder 30 to be managed, and thereby to determine whether or not to collect the shredded waste.
In the case of this example, it is not always possible to say that the number of sheets of the bundle of sheets Sa is the specified number. It is preferable to perform correction such as multiplication by a weighting factor.

◎Embodiment 6
FIG. 25 shows a main part of a waste disposal device used in the waste management system according to the sixth embodiment.
In the same figure, the waste processing device 700 is an embodiment in which a shredder 710 as a shredded waste processor and a recovery box 720 as a non-shredded waste processor are integrated.
In this example, the waste processing apparatus 700 integrates a shredder housing 711 and a collection box housing 721 so as to partition the interior with a common partition wall 716, and opens an inlet 712 at the top of the shredder housing 711. A carrying-in path 713 is provided, a shredding mechanism 714 is installed in the middle of the carrying-in path 713, and a waste container 715 is installed below it so that it can be moved in and out. , and a waste container 723 is installed therein. The recovery box housing 721 is provided with a locked door (not shown).
Further, the shredder housing 711 is provided with a waste amount sensor 731 for detecting the amount of shredded waste in the waste container 715, while the collection box housing 721 is also provided with the waste amount sensor 731 for detecting the amount of waste waste in the waste container 723. A waste amount sensor 732 is provided, and detection outputs of these waste amount sensors 731 and 732 are taken into a control device 733 common to both, connected to a network via a communication unit 734 common to both, and communicated with a management base. Communication is enabled.
Therefore, in substantially the same manner as in the first embodiment, the amounts of waste in the shredder 710 and the collection box 720 are transmitted to the management base, and the management base determines whether or not the waste collection operation is necessary.

◎ Example 1
This example shows an example of a management screen display of the management device 100 used in the shredder shredded waste management system among the waste management systems according to the first embodiment, for example.
FIG. 26 shows an example of a management screen display for managing shredders to be managed by Company A. FIG.
In the figure, machine information of the managed shredder 30 is displayed in the upper area of the management screen. In addition, in the lower area of the management screen, when the full level of the accumulated amount monitor of shredded waste is 100%, 20% from the full level side is color-coded (for example, red, orange, yellow, green, yellowish green). ing.
Also, as action determination levels, when the accumulated amount of shredded waste is 85%, collection is required on the same day, when the amount is 70%, collection preparation A is indicated, and when the amount is 55%, collection preparation B is indicated.
In the right column, the scheduled collection date is calculated and written based on the current situation. Below the scheduled collection date, there is a button for "view past history", and for information on the piled amount monitor, there are a button for "confidential document accumulation status" and a "shredded amount status" button. It is

Now, when the "shredded amount status" button in FIG. 26 is pressed, as shown in FIG. 27, as the shredded amount status, the current shredded amount and the cumulative total for the current month are displayed both graphically and numerically.
Also, when the "confidential document accumulation status" button in FIG. 26 is pressed, daily changes in the level of accumulated amount for the current month are displayed in a bar graph as shown in FIG. 28, and the accumulated amount of shredded waste reaches 80% It has been analyzed that the cycle to do is 8 days.
Furthermore, when the "view past history" button in FIG. 26 is pressed, the number of Soi clusters for each month in the past year is displayed in a bar graph as shown in FIG. is displayed.
With such a display example, it is possible to grasp changes in the amount of shredded waste accumulated in the managed shredder 30 in real time at predetermined intervals (for example, one day) at the management base.

◎ Example 2
This example shows a method of determining the amount of shredded waste used in the shredder shredded waste management system of the first embodiment.
In this example, it is generally known that when a plurality of sheets of paper to be shredded are loaded into the shredding mechanism 34, the load current of the drive motor of the shredding mechanism 34 varies according to the number of sheets of paper to be shredded. A method is employed in which an indicator such as an LED is used to display such as changing the display color according to the amount of load when shredding is being performed using a . For example, in the management screen display example shown in FIG. 27, the colors are displayed in red, orange, yellow, green, and yellow-green in descending order of load.
Now, in the measurement circuit shown in FIG. 30(a), the load current of the drive motor (in this example, an induction motor is used) is taken out by the take-out circuit with the rectifier diode and the operational amplifier, and the When it was made to take in from the port, the result shown in FIG.30(b) was obtained.
It can be understood from FIG. 30(b) that the load current of the drive motor fluctuates when the paper is loaded into the loading slot sensor. At this time, the analog level A is determined after equalization by sampling the load current.

Changes in the load current for each number of sheets to be shredded are shown in FIGS. 31(a) and (b).
31(a) shows an example of measurement data showing the relationship between the number of shredded sheets and the load current in Example 2, and (b) shows the number of shredded sheets, the shredding speed, and the shredding time of the second embodiment. It is an example of measurement data showing the relationship.
According to the figure, when the number of sheets to be shredded is small, the load current value is small and fluctuates depending on the state of shredding.
Also, it is understood that when the number of sheets to be shredded is small, the speed of shredding tends to be high, and when the number of sheets to be shredded is large, the speed of shredding tends to be low. However, since the fluctuation range is about 15%, it is considered that the degree of contribution to the number of pieces to be shredded is small.
Therefore, it is possible to calculate the number of sheets to be shredded by the following calculation.
(1) In the case of 50Hz ・1 sheet after about 40 seconds at current value of 3.1A ・20 sheets after about 5.0 seconds at current value of 9.0A ・about 20.0 seconds at current value of 9.0A Elapsed time can be calculated from the relationships shown in FIGS. 31(a) and 31(b), such as 80 sheets.
In addition, since there is a change in the current value at the time of intermittent feeding or a change in the number of pieces to be shredded, the calculation can be performed by resetting at that time.
(2) In the case of 60 Hz, it can be similarly calculated from FIGS.
(3) When A4 paper, which is the standard size of paper, is fed horizontally, the load current value increases but the shredding time decreases compared to when A4 paper is fed vertically, so there is no problem with the calculation method.
(4) Even in the case of thick paper, it may be converted to the paper calculated here (for example, high-quality paper).
(5) Each time the material is shredded, the data is recorded for a predetermined period. Also, if the daily number of sheets to be shredded is notified to the management center through a communication line, it can be managed.

◎ Example 3
FIGS. 32(a) and 32(b) show a method of determining the amount of shredded waste used in the shredder shredded waste management system of the first embodiment.
However, unlike Example 2, the case where an inverter motor is used as a drive motor is shown.
FIG. 32(a) is an example of measurement data showing the relationship (50 Hz) between the number of shredded pieces and the load current, and (b) shows the relationship (50 Hz) between the number of shredded pieces and the shredding speed and shredding time. It is an example of measurement data shown.
According to the figure, it was confirmed that even if the drive motor was an inverter motor, it was possible to calculate the number of sheets to be shredded in the same manner as in the second embodiment.
It is also understood that the present embodiment can shred a larger number of sheets than the second embodiment.
