FIG. 6 is a functional block diagram of a control device provided in the processing machine of the present embodiment.
In FIG. 6, the control device 70 is configured such that the processing amount calculation unit 71 that calculates the production amount of the processed material based on the measurement value by the conveyance amount measuring unit 60 and the flash memory that stores various data are turned off. A nonvolatile storage unit 72 that stores stored information, a time measurement unit (timer) 73 that measures time, and an operation management unit 74 that restricts the amount of crushed material produced under the set conditions are provided. The control device 70 can be connected to a dedicated recording means 80 that can rewrite the storage information in the storage section 72, and an authentication section that determines whether the recording means 80 rewrites the storage information in the storage section 72. 75 is provided.

  In the storage unit 72, a set period storage unit 71a that stores a predetermined set period, a time storage unit 72b that stores the time when the crushing apparatus 20 is first activated as a starting time, and production is allowed within the set period. A maximum production amount storage unit 72c for storing the maximum production amount of the crushed material, and a production amount storage unit 72d for storing data of the processing amount calculated by the processing amount calculation unit 71 in time series. . Each of the storage units 71a to 72d is a nonvolatile memory. Information stored in the setting period storage unit 71a and the maximum production amount storage unit 72c is set by the recording unit 80. The setting period and the maximum production amount are set by connecting the recording unit 80 to the control device 70, and it is authenticated that the recording unit 80 is a dedicated tool that is permitted to rewrite the storage information in the storage unit 72 by ID information or the like. When authenticated by the unit 75, the setting input by the recording unit 80 is validated, and the setting input by the recording unit 80 is appropriately reflected (rewritten) in the storage information of the setting period storage unit 71a and the maximum production amount storage unit 72c. . If the setting period is one day unit, only hour / minute time information is sufficient. However, when the setting period spans days such as two-day unit, week unit, month unit, etc. Date / time information is also required. When the set period spans months and years, time information of the month and year is necessary. Alternatively, if it is not necessary to manage until the hour and minute, the time management can be performed in units of days.

  In the present embodiment, the configuration in which the stored information in the storage unit 72 can be rewritten only when the dedicated recording unit 80 is connected in this way is exemplified. Only a specific person who knows the password can rewrite the information stored in the storage unit 72. Further, when rewriting at the operation site is not permitted, at least the setting period storage unit 71a, the maximum production amount storage unit 72c of the storage unit 72, and if necessary, the time storage unit 72b is read-only storage information that cannot be rewritten. A configuration using a memory may also be used.

  The operation management unit 74 manages the elapsed time from the starting time measured by the time measuring unit 73, and before the elapsed time from the starting time reaches the set period, the accumulated production amount of the crushed material after the starting time is When the maximum production amount is reached, until the set period is reached, the grizzly feeder 15, the crushing device 20, and the discharge conveyor 25 are stopped and cannot be activated. In the present embodiment, a supply line for working fluid (pressure oil) from a hydraulic pump (not shown) of the power unit 40 to the feeder drive unit 19, the crusher drive unit 21, and the discharge conveyor drive unit 27 is provided. Control valves 76-78 for blocking the flow of the working fluid are provided. When the grizzly feeder 15, the crushing device 20, and the discharge conveyor 25 are stopped and cannot be started, the operation management unit 74 controls the control valves 76- 78 is switched to the shut-off position, and the signal for instructing switching to the control valves 76-78 is invalidated until the set period elapses (the command signal corresponding to the operation is not output even if there is an operation). As the control valves 76-78, an existing control valve in the power unit 40 that controls the flow of the working fluid to the feeder drive unit 19, the crushing unit drive unit 21, and the discharge conveyor drive unit 27 can be used. For example, a two-position switching type control valve added separately can be used. Moreover, in this Embodiment, although the operation management part 74 has taken the structure which makes the grizzly feeder 15, the crushing apparatus 20, and the discharge conveyor 25 inoperable on said conditions, when restricting the production of crushed material, It is sufficient that at least the crushing device 20 is stopped.

  In addition, when making the crushing apparatus 20 grade | etc., Stop and making it unstartable, there exist various alternative methods besides hold | maintaining the control valves 76-78 in the interruption | blocking position. For example, the control device 70 invalidates the operation command and does not output a command signal for the control valve even if an operation signal from an operation panel (not shown) is input until the set time elapses after the maximum production amount elapses. It can be replaced. A configuration in which the engine is held in a stopped state and the hydraulic pump is not driven can be used.

Next, the operation of the jaw crusher of the present embodiment having the above configuration will be described.
When the object to be crushed is put into the hopper 12 by a hydraulic excavator or the like, the thrown object to be crushed is guided onto the grizzly feeder 15 and conveyed toward the crushing device 20 by vibration. At that time, fine grains (slipping etc.) smaller than the gaps between the comb teeth 17 of the grizzly river 18 are guided to the discharge conveyor 25 through the chute 11 from the gaps, and a larger object to be crushed (large lump). Is supplied to the crushing device 20. The object to be crushed supplied to the crushing device 20 is crushed to a predetermined particle size corresponding to the exit gap between the fixed tooth 42 and the moving tooth 43 and introduced onto the lower discharge conveyor 25. The crushed material guided on the discharge conveyor 25 merges with the fine particles guided through the chute 11 and is conveyed forward (right side in FIG. 1), and adsorbs foreign matters such as reinforcing bars by the magnetic separator 35 in the middle. After being removed, it is discharged out of the machine.

  FIG. 7 is a flowchart showing an operation management procedure by the control device 70.

  For example, when the jaw crusher of the present embodiment is rented or delivered, when the activation operation (power ON) is performed for the first time at the rental destination or the delivery destination, the operation management unit 74 first sets the time as the starting time in step S101. While storing in the memory | storage part 72b, the memory | storage information of the production-volume memory | storage part 72d is cleared, and an accumulated production amount is set to 0 (zero). Thereafter, upon receiving an instruction to start the crushing operation by the operator's operation, the grizzly feeder 15, the crushing device 20 and the discharge conveyor 25 are started in the subsequent step S102, and the calculation of the accumulated production amount of the crushed material is started in step S103. The amount of crushed material per unit length of the conveyor belt, which is calculated at any time by the processing amount calculation unit 71 based on the detection signal from the conveyance amount measuring means 60, is cumulatively calculated. The calculated cumulative production amount is stored in the production amount storage unit 72d.

  In the present embodiment, the case where the first activation time is set as the start time has been described as an example. However, for example, when the grizzly feeder 15, the crushing device 20, and the discharge conveyor 25 are activated and are simultaneously driven. It is also possible to estimate that the crushing operation has actually started and set the time as the starting time. Moreover, when defining the start time of the crushing operation, the time when at least one of the three devices including the crushing device 20 is activated can be set as the starting time.

  The operation management unit 74 monitors the elapsed time from the start time based on the measurement time of the time measurement unit 73, and in step S104, the set time stored in the set period storage unit 72a is the elapsed time from the start time. Determine whether or not When the set period elapses from the starting time, the determination in step S104 is satisfied at that time, and the procedure proceeds to steps S105 and S106 sequentially. The processing contents of steps S105 and S106 are the same as those of the previous steps S101 and S103. In this case, the restriction on the production amount of the setting period is released as the setting period elapses, and the accumulation from the starting time updated in step S105. The production amount is calculated in step S106. Thereafter, when the operator does not stop the processing machine, the operation management unit 74 moves the procedure from step S107 to step S108, stops the grizzly feeder 15, the crushing device 20, and the discharge conveyor 25, and ends the crushing operation. . In particular, when there is no operation to stop the processing machine by the operator, the operation management unit 74 returns the procedure from step S107 to step S104, continues the crushing operation, and monitors the passage of time.

  In step S104, if the set period has not elapsed since the start time, the operation management unit 74 moves the procedure to step S109, and the accumulated production amount (the final production amount information in the production amount storage unit 72d) from the start time is maximum. It is determined whether the maximum production amount stored in the production amount storage unit 72c has been reached. If the maximum production amount has not been reached at this point, the operation management unit 74 moves the procedure to step S106, and continues to cumulatively calculate the production amount. In this case, since the process does not go through step S105, the cumulative production amount from the previous calculation time updated in step S105 is calculated in step S106. On the other hand, if the accumulated production amount reaches the maximum production amount before the set period elapses, the determination in step S109 is satisfied at that time, and the operation management unit 74 moves the procedure to step S108 and turns off the control valves 76-78. , The grizzly feeder 15, the crushing device 20, and the discharge conveyor 25 are stopped to forcibly end the crushing operation.

  Thereafter, even if the activation operation is performed again, the operation management unit 74 keeps the control valves 76-78 at the shut-off position until the set period is reached, and refuses to start the crushing operation. When the activation operation is performed again, the start of the crushing operation is permitted if the set period has elapsed, and the procedure from step S101 is executed in accordance with the operator's instruction.

  As described above, in the jaw crusher of the present embodiment, for example, when the maximum production amount per day (set period) is limited to 100 t, the production of 100 t of crushed material is detected until 1 day elapses. The machine will be forcibly stopped until one day has passed. For example, if the maximum production per month (set period) is limited to 5000 t, the production of 5000 t of crushed material will be detected until 1 month elapses regardless of the production per day (the pace of production). At this point, the machine is forcibly stopped, and the crushing operation becomes impossible until one month has passed.

According to this embodiment described above, the following effects can be obtained.
(1) Optimization of operation management When the jaw crusher of this embodiment is rented, if the rental fee is calculated based on the operation time and load factor data, the type and properties of the object to be processed, and the high load state If the operation at is continued, the consumable parts of the crushing device 20 may be consumed in a short time. The moving teeth, fixed teeth, cheek plates, etc. in the crushing device 20 are replacement parts that are consumed during the crushing operation, but they are made of a hard material because they come into contact with various objects to be crushed during the crushing process. Surface treatment such as quenching is performed, and it is very expensive. As a result, there may be a disparity between the degree of wear of the aircraft and the rental fee. Although the present embodiment exemplifies a jaw crusher, other processing machines similarly have expensive consumable parts that directly act on the workpiece inside the processing apparatus. For example, a crushing bit / anvil / screen for a wood crusher, a paddle / liner plate for a soil improvement machine, and a cutter for a shredder.

  On the other hand, according to the present embodiment, by managing the production amount of crushed material, the rental fee based on the production amount can be calculated, so the rental fee and the degree of consumption of the aircraft must be balanced. Can do. Further, for example, if a maximum production amount per unit period (set period) is determined at the time of a loan contract and the information is set in the set period storage unit 72a and the maximum production amount storage unit 72c in advance, the set period Limiting the amount of production inside can also suppress excessive wear of the aircraft. In addition, in the operation site of various processing machines including a jaw crusher, processed products such as crushed materials are usually traded by weight or volume.

  Therefore, it is possible to contribute to proper operation management of the processing machine by managing the production amount of the processed material and limiting excessive production as in the present embodiment.

(2) Production volume management For example, when using a processing machine for waste disposal, the amount of treatment allowed per day or month is generally restricted by regulations or regulations due to consideration of the surrounding environment at the waste disposal site. ing. In addition, the amount of production is also determined when a soil improvement material (lime, bentonite, etc.) is mixed with earth and sand using a soil improvement machine among the processing machines to produce a material for a water shielding layer in a final disposal site. In this way, for example, when a processing machine is operated at a site where only 10 tons per day should be produced and there should be no more than 10,000 tons per month, a preset period or maximum production will be met. By setting the amount, you can comply with the restrictions, which is also useful for construction management.
