In the structure described in the above-mentioned patent document, a stepwise pulverization process is performed by coarse pulverization with oblique internal teeth and oblique external teeth and fine pulverization with upper and lower pulverized surfaces. be able to. Therefore, it is useful in that the pulverization process can be efficiently performed with relatively little heat generation, compared to the structure in which fine pulverization is performed by rubbing the upper pulverized surface and the lower pulverized surface without a coarse pulverized portion. Is.
However, in this structure, a fine pulverization portion is provided by the upper pulverization surface and the lower pulverization surface immediately after the coarse pulverization portion by the oblique internal teeth and the oblique external teeth. The object to be processed after being pulverized is immediately subjected to a fine pulverization process. At this time, the object coarsely pulverized in the coarsely pulverized portion in the central part is diffused in the radial direction so that fine pulverization can be efficiently performed in a large area. In short coarse pulverized portions, the processing tends to be faster than fine pulverization. Therefore, the subsequent processing object waits for the processing of the preceding processing object in the pulverization unit to be completed, and the flow of the subsequent processing object from the crushing unit to the pulverizing unit side is stagnated. The object to be treated tends to have heat by being subjected to an excessive pulverization process in the coarse crushing portion, and there is room for improvement in this respect.

Image data photographed by the input detector 17 is input to the control device 100, and it is determined whether or not the object to be processed in the input port hopper 11 is made of a different material.

  A receiving hopper 12 having an upper end side opening 12A facing the lower end side outlet 11D is provided below the lower end side outlet 11D of the charging port hopper 11. The receiving hopper 12 is also formed in a constricted shape with a lower surface 12B composed of a downward inclined surface inclined so as to be positioned downward as it goes away from the upper end side opening 12A. And the residue detector 18 is provided in this inclined lower surface 12B, and it is comprised so that the pressure of the to-be-processed object which exists in the receiving port hopper 12 can be detected. A detection signal from the residue detector 18 is input to the control device 100 to determine whether or not an object to be processed exists in the receiving port hopper 12.

The receiving hopper 12 is formed in a shape that is inclined so that the upper end side opening 12A is also positioned on the lower side as the side closer to the mounting panel 1, and the upper end side opening 12A is formed on the different material hopper 13 near the inclined lower end side. On the other hand, a flow guide plate 14 is provided for allowing the workpiece to flow down.
The flow guide plate 14 is located at a position where the edge on the upper end side of the slope substantially coincides with the extended line of the slope of the lower surface 11C of the inlet hopper 11, or at a position slightly below it, as shown in FIG. In this way, the workpiece to be processed that has been loaded into the charging port hopper 11 slides down through the lower surface 11C of the charging port hopper 11 and the tip inclined surface 15a of the different material take-out shutter 15 at the closing position described later. It is configured not to prevent the flow down to the receiving port hopper 12.

In addition, the flow down guide plate 14 can guide and feed the workpiece, which is determined to be a different material discharged from the lower end side outlet 11D of the inlet hopper 11, to the different material hopper 13 in the storage position. The position of the edge on the inclined lower end side is set so as to be positioned closer to the different material hopper 13 in the horizontal direction than the position of the lower end side outlet 11D of the inlet hopper 11.
Therefore, as shown in FIG. 6, when the different material take-out shutter 15 is operated to the open position, the object to be processed that has been determined to be a different material falling from the lower end side outlet 11 </ b> D of the inlet hopper 11 is moved to the flow guide plate 14. It is dropped and supplied to an intermediate position in the inclined direction of the inclined guide surface 14a.

In this state, an object to be processed in the inlet hopper 11 is detected by the input object detector 17, and whether or not the object to be processed corresponds to a different material is detected by the detection signal from the input object detector 17. The determination is made by the control device 100 based on this.

  When it is determined that the object to be processed put into the inlet hopper 11 does not correspond to a different material, and the residue detector 18 provided in the inlet hopper 12 does not detect the residue, the grain is put in. As the opening 11A is closed and the grain input port 11A is switched to the locked state by the lock mechanism 6, the opening / closing solenoid 8 operates the outlet shutter 16 to the open side, so that the inlet hopper 11 and the inlet hopper 11 are opened. The material to be processed is supplied to 12.

When it is determined that the object to be processed put into the inlet hopper 11 is equivalent to a different material, the opening / closing solenoid 8 maintains the closing posture of the outlet shutter 16, and the different material of the mounting panel 1. The indicator lamp 4d lights up. At the same time, the coins that have already been inserted are returned to the change return port 3B.
When the different material take-out shutter 15 is artificially pulled out and switched to the open position in accordance with the display of the different material indicator lamp 4d, the flow of the material to be processed flows from the inlet hopper 11 to the different material hopper 13 as shown in FIG. Is done.

[Crushing section]

The distance between the outer peripheral surface of the lower mortar 22 and the inner peripheral surface of the upper mortar 21 is wider toward the upper side and narrower toward the lower side. Even in the process of coarse pulverization, it is coarser on the upper side and slightly smaller on the lower side. To be crushed.

The cylindrical upper mill 21 includes a flange portion 21a on the lower end side. By mounting this flange portion 21a on the upper surface of the support base 23 fixedly installed on the upper side of the upper mounting frame 1A provided on the back side of the mounting panel 1, the upper die 21 is supported by the support base 23. Is fixedly supported.
The ceiling portion 21b of the upper mill 21 is configured to support the lower end portion of the receiving port hopper 12 and to introduce the workpiece from the lower end side opening 12C of the receiving port hopper 12. In addition, the ceiling portion 21b is a shaft for supporting the upper end portion of the power transmission shaft 53 that transmits driving force to the lower milling die 32 and the lower milling mill 32 of the milling unit 30 described later together with the lower milling die 22. A branch 24 is provided.

The shaft support portion 24 is inserted into the pivot hole 22a of the lower mortar 22 at the lower end side, and the pivot shaft 25 pivotally supports the lower mortar 22 so as to be relatively rotatable, and the upper end portion 25a of the pivot shaft 25 is located on the upper side. And an urging spring 26 for urging and energizing. That is, the pivotal support hole 22a of the lower die 22 is formed as a stepped hole whose upper side has a small diameter, and the support shaft 25 is formed as a stepped shaft whose lower side has a large diameter. The step portion 25b of the support shaft 25 abuts and engages with the step portion 22b of the pivot support hole 22a in the vertical direction, and the support shaft 25 is urged upward by an urging spring 26 formed of a coiled compression spring. The outer peripheral surface of the lower die 22 is always pressed and urged toward the inner peripheral surface side of the upper die 21.
Accordingly, as shown in FIG. 7 (a), when the workpiece introduced from the lower end side opening 12C of the receiving hopper 12 is introduced between the lower mortar 22 and the upper mortar 21 and pulverized, FIG. As shown in b), it is possible to allow the lower mortar 22 to be pushed down somewhat downward while resisting the urging force of the urging spring 26 by the reaction force accompanying the crushing of the workpiece.

Between the lower die 22 and the power transmission shaft 53 that transmits a driving force to the lower die 22, the following transmission structure is provided to allow the lower die 22 to move up and down.
That is, a fitting hole portion 22c formed by a hexagonal hole is provided at the lower end portion of the lower mill 22 and the hexagonal shaft portion 55a of the upper transmission shaft 55 of the power transmission shaft 53 is fitted into the fitting hole portion 22c. The rotary power is transmitted to the lower die 22. A round hole 22d into which the large-diameter portion of the support shaft 25 is inserted is formed on the upper side of the fitting hole 22c of the lower mortar 22, and the hexagonal shaft portion of the power transmission shaft 53 is formed in the round hole 22d. A round shaft portion 55b formed above 55a is inserted and supported.
A power transmission structure from the power transmission shaft 53 to the lower mill 22 is constituted by the fitting hole portion 22c, the hexagonal shaft portion 55a, the round hole 22d, and the round shaft portion 55b.

Further, as shown in FIGS. 7A and 7B, the length of the round hole 22d and the length of the round shaft portion 55b of the power transmission shaft 53 are lower than the lower end of the support shaft 25 of the lower mortar 22. The vertical lengths are approximately the same. And in the state (state shown in Drawing 7 (a)) where the outer peripheral surface of lower mill 22 touched the inner peripheral surface of upper mill 21, it is between the lower end part of round hole 22d, and the lower end part of round shaft part 55b. The relative positions of the lower mortar 22 and the upper mortar 21 are determined so that the accommodation gap s having a predetermined vertical length is generated.
By configuring the relative positions of the lower mill 22 and the upper mill 21 in a state where the accommodation gap s exists, as shown in FIG. 7B, the lower mill 22 is caused by the reaction force accompanying the crushing of the workpiece. Can be allowed to be pushed downward within a predetermined range.

And a power transmission structure to the lower die 22 provided.

The object to be processed crushed by the crushing unit 20 is supplied to the lower pulverizing unit 30 through the movement path r from between the outer peripheral surface of the lower mill 22 and the inner peripheral surface of the upper mill 21 and further finely divided. Although being crushed, the moving path r is formed inside the support base 23.
That is, as shown in FIGS. 4 and 9, the support base 23 has an upper end facing the flange portion 21 a on the lower end side of the upper die 21, and an outer peripheral surface of the lower die 22 and an inner peripheral surface of the upper die 21. The workpiece to be processed has a large diameter so as to support the upper die 21 on the outer side of the facing portion of the lower die 22 and falls from the facing portion between the outer peripheral surface of the lower die 22 and the inner peripheral surface of the upper die 21. 23 is configured to be supplied to the inside.

The inner surface side of the support table 23 is formed in an inverted conical shape with a constricted bottom, and an object to be processed that falls from a position where the outer peripheral surface of the lower die 22 and the inner peripheral surface of the upper die 21 are opposed to each other. The power transmission shaft 53 located at the center and the workpiece introduction port 30 </ b> B of the pulverization unit 30 located on the outer peripheral side of the power transmission shaft 53 are configured to be collected.
And the inside of this support stand 23 stores temporarily the to-be-processed object before being taken in into the pulverization part 30, without preventing the state by which the to-be-processed object pulverized by the crushing part 20 falls and is supplied. Thus, the storage space 23A having a sufficient volume is configured.

As described above, the support base 23 has a function as a support means for supporting the crushing unit 20, and feeds the processing object dropped and supplied from the crushing unit 20 to the pulverizing unit 30 while guiding it. The function as means for forming the movement path r, and the time lag between the processing time by the crushing unit 20 and the processing time by the pulverizing unit 30 by temporarily storing the object to be processed before being taken into the pulverizing unit 30 It also has a function as a buffer to eliminate.
That is, the pulverization unit 20 and the pulverization unit 30 generally have different pulverization processing times of the workpieces, and the pulverization unit 30 tends to require longer processing time than the pulverization unit 20. For this reason, in the structure in which the processing object is immediately sent from the crushing unit 20 to the refining unit 30 and processed, the processing object on the side of the crushing unit 20 that has finished the crushing process is the refining unit 30. It is difficult to be smoothly fed to the crushing unit 20 and may stagnate. However, according to the present invention, the object to be processed before being fed into the refining unit 30 is stored in the storage space 23A provided in the movement path of the object to be processed from the crushing unit 20 to the refining unit 30. Since it is stored temporarily, it can avoid that a to-be-processed object stagnates in the crushing part 20. FIG.
Thereby, it is avoided that the influence of the heat generated by the object to be processed staying in the crushing part 20 reaches the object to be processed, and the object itself is radiated while being stored in the storage space 23A. Therefore, it also functions as a heat radiating means for avoiding a thermal influence on the object to be processed.

When supplied to 41, an end indicator lamp 4f provided near the upper portion of the take-out recess 43 having an opening on the front side of the mounting panel 1 is turned on.
Since the completion of the pulverization process can be known by observing the lighting of the end indicator lamp 4f, the processing object stored in the granular material collection unit 41 is taken out downward by pulling out the operation panel 42 for extraction. It can be dropped and supplied to the recess 43.
Therefore, by placing the receiving container 44 in the take-out recess 43 as indicated by a virtual line, the object to be processed that has been milled can be taken out to the outside.

〔Drive part〕
The drive part 50 which transmits a driving force to the crushing part 20 and the fine crushing part 30 is comprised as follows.
As shown in FIGS. 2 to 4, the drive unit 50 includes a first electric motor 51 and a second electric motor 52 as power sources. The driving force of the first electric motor 51 is transmitted to the crushing unit 20 and the refining unit 30 as rotational power for crushing via a power transmission shaft 53 connected to the first electric motor 51. Has been.
The power of the second electric motor 52 is used not to drive the power transmission shaft 53 but to move the power transmission shaft 53 up and down in the vertical direction via a screw feed mechanism 57 as a vertical position changing mechanism. Used as power. In other words, by moving the power transmission shaft 53 up and down in the vertical direction, the lower pulverizing mill 32 integrally connected to the power transmission shaft 53 is moved in the vertical direction to move the upper pulverizing mill. It is comprised so that the opposing space | interval with 31 can be changed.

The first electric motor 51 and the second electric motor 52 are connected and fixed to a lower mounting frame 1B provided on the back side of the mounting panel 1, and their vertical and horizontal positions are determined.
The power transmission shaft 53 is positioned concentrically with the output shaft 51a of the first electric motor 51, and the boss portion 54b on the lower end side of the lower transmission shaft 54 and the output shaft 51a are key-connected to rotate integrally. It is configured. Further, the lower transmission shaft 54 is configured to be movable relative to the output shaft 51a in a vertical range although it is a slight range in the axial direction.

  An output rotator 52b is mounted on the output shaft 52a on the upper end side of the second transmission motor 52, and a timing belt 52c is stretched between the output rotator 52b and the passive rotator 58 of the screw feed mechanism 57. The passive rotating body 58 of the screw feed mechanism 57 is driven to rotate synchronously with the rotation of the output shaft 52a of the two electric motor 52.

  The screw feed mechanism 57 as the vertical position changing mechanism is formed on the passive rotating body 58 that is fitted on the outer peripheral portion of the lower transmission shaft 54 of the power transmission shaft 53 so as to be relatively rotatable, and on the passive rotating body 58. It is comprised by the intermediate member 59 screwed with respect to the screw part 58a which has it. The intermediate member 59 has a screw hole 59a that is screwed into a screw portion of the passive rotating body 58 on the lower side, and has an upper portion below the step portion 54d formed below the large-diameter portion 54c of the lower transmission shaft 54. A thrust bearing 59b is provided to contact from the side. And although not shown in figure, it is supported so that it can move only to an up-down direction in the rotation prevention state so that it cannot rotate to the appropriate position of the attachment panel 1. FIG.

That is, when the passive rotating body 58 is rotationally driven in one direction, the position of the intermediate member 59 screwed to the passive rotating body 58 is changed upward or downward. When the passive rotating body 58 is rotationally driven in the reverse direction, the intermediate member 59 is also configured to change its position downward or upward.
Therefore, when the intermediate member 59 moves upward, the step 54d of the lower transmission shaft 54 is pushed upward via the thrust bearing 59b, and the lower pulverizing mill 32 is subjected to upper pulverization as the lower transmission shaft 54 moves upward. Move to the side close to the mortar 31.
On the contrary, when the intermediate member 59 moves downward, the lower transmission shaft 54 is moved downward by the self-weight movement of the lower transmission shaft 54 in the state of supporting the stepped portion 54d via the thrust bearing 59b. Thus, the lower pulverizing mill 32 moves to the side away from the upper pulverizing mill 31, and the facing distance from the upper pulverizing mill 31 is increased.

[Cleaning cleaner]
As shown in FIGS. 3 and 8, a cleaning cleaner 60 having a suction duct 61 is connected to the granular material collection unit 41 connected to the powder outlet 30 </ b> C of the pulverization unit 30.
The cleaning cleaner 60 includes a suction duct 61 in which an end on the suction side is connected to a granular material collection unit 41 that is disconnected from the outside in a state where the take-out operation plate 42 is operated to a closed position. ing. The end of the suction duct 61 on the discharge side is connected to a dust collection unit 62 for separating dust and a suction fan 63. As the suction fan 63 is driven, the gas in the granular material collection unit 41 and its gas It is configured to suck and discharge contained dust and the like.

When the inside of the powder collection unit 41 becomes negative pressure by driving the suction fan 63, the refining chamber 34, the movement path r, and the crushing unit 20 of the refining unit 30 communicating with the powder collection unit 41 are connected. The suction action is also exerted on this. As a result, the gas existing in the range of the suction action, the remaining powder of the object to be processed, and the like are sucked and discharged.
The dust collecting unit 62 and the suction fan 63 of the cleaning cleaner 60 are installed at appropriate places such as the floor surface in the machine room S2, but may be installed outside the machine room S2.

  As shown in FIG. 8, the powder outlet 30 </ b> C from the pulverization unit 30 is displaced to a position closer to one end side than the center position in the horizontal direction of the powder collection unit 41 with respect to the powder collection unit 41. It is provided at the position. The suction port 61a, which is the end of the suction duct 61 on the suction side, is disposed at a position away from the powder outlet 30C at a location near the other end opposite to the side where the powder outlet 30C is displaced. Has been.

〔Control device〕
As shown in FIG. 10, the control device 100 includes a display control unit 101 that outputs control signals to the various display devices 4, an input situation determination control unit 102, a crushing control unit 103, and a cleaning control unit 104. I have.

The display control unit 101 is in a state where it is impossible to input grain if it is in operation based on the determination result of whether the input state determination control unit 102, the crushing control unit 103, or the cleaning control unit 104 is in operation. The status display lamp 4a for indicating the presence is turned on.
If it is not in operation, the start indicator lamp 4b indicating that the grain can be inserted from the grain insertion slot 11A is displayed based on a detection signal indicating that a predetermined amount of coins has been inserted from the coin detector 3. Do.
At the same time, based on the detection signal from the residue detector 18, if there is any residue in the receiving hopper 12, this is displayed on the residue indicator lamp 4e.

When it is determined, based on the detection result of the input detector 17 that detects an object to be processed that has been input to the input port hopper 11, that the input is not an object to be processed, that is, not milled rice. Then, the different material indicator lamp 4d is turned on.
In addition, the granularity selection lamp 5c displays which of the coarse grinding selection switch 5a, the intermediate grinding selection switch 5b, and the fine grinding selection switch 5c, which is the granularity selection switch 5, is selected.

  Based on the detection signal from the residue detector 18, the throwing state determination control means 102 outputs a detection signal indicating the presence of residue to the display control means 101, and sets the exit shutter 16 to the opening / closing solenoid 8. Output control command to open. At the same time, a control signal for processing the residue is output to the crushing control unit 103 and the cleaning control unit 104, and the crushing unit 20, the crushing unit 30, and the cleaning cleaner 60 are driven to crush the residue. And cleaning after crushing.

In addition, when the input material detector 17 detects that the material is a different material, the input status determination control unit 102 outputs a detection signal indicating that the material is different to the display control unit 101.
There is a detection signal that the crushing control means 103 and the cleaning control means 104 are not in operation, the input is not a different material, and a predetermined amount of coins from the coin detector 3 has been inserted, and the particle size selection switch 5 After the particle size of the processed product is selected, when it is detected that the opening / closing lid 11B of the charging port 11A is closed by the loading port switch sw, the loading status determination control unit 102 sends these detection signals to the crushing control unit 103. Output.

In the pulverization control means 103 (corresponding to a control means for setting the pulverization time in the pulverizing unit 30 to such an extent that a minute amount of granular processed material remains in the pulverizing unit 30 at the end of the pulverization step), the input situation determination control means The first electric motor 51 is driven based on the detection result at 102, the second electric motor 52 is driven based on the selection result at the particle size selection switch 5, and the position of the lower pulverizing mill 32 in the pulverizing unit 30 Is appropriately adjusted to determine the pulverized particle size in the pulverizing unit 30.
In addition, the blower 38 of the cooling device 35 is driven along with the driving of the first electric motor 51.
The operation time of the crushing process in the crushing unit 20 and the refining unit 30 by the first electric motor 51 and the operation time of the blower 38 are determined by the set time stored in advance in the crushing control means 103 as a program. The operation time of the first electric motor 51 set by the pulverization control means 103 is such that, at the end of the pulverization step, only a small amount of the processing object having a particle size slightly larger than the final target particle size is present in the pulverization unit 30. It is desirable to set it to the remaining level. This is because it is easier to clean the inside of the refinement chamber 34 more cleanly when performing the cleaning while driving the refinement unit 30 in the subsequent cleaning process. This phenomenon makes it easy to peel off by contacting the fine powder adhering to the chamber wall of the pulverization chamber 34 when the slightly remaining processing object having a large particle size moves in the pulverization chamber 34. This is probably because of this.

In the cleaning control means 104 (corresponding to a control means for performing a suction operation by the cleaning cleaner 60 in a driving state of the crushing unit 20 and the pulverizing unit 30 after the crushing process is finished), a detection signal from the residue detector 18 is used. A drive command is output to the suction fan 63 based on a cleaning process based on the command and a command from a push button type cleaning start switch 9 provided on the front side of the mounting panel 1.
At this time, the cleaning control means 104 drives the first electric motor 51 to control the suction by the suction fan 63 while the crushing unit 20 and the pulverizing unit 30 are driven. The driving speed of the crushing unit 20 and the pulverizing unit 30 at this time is the same as the driving speed in the normal crushing process, but the driving speed may be controlled so as to be driven at a slower driving speed.

  The cleaning control unit 104 also outputs a drive command to the second electric motor 52. The driving of the second electric motor 52 in the cleaning process narrows the space between the upper pulverizing mill 31 and the lower pulverizing mill 32 at the initial stage of the cleaning process, and the upper pulverizing mill 31 and the lower pulverizing mill at the final stage of the cleaning process. Control is performed to widen the space between the grinding mill 32. Or conversely, at the initial stage of the cleaning process, the space between the upper pulverizing mill 31 and the lower pulverizing mill 32 is widened, and at the end of the cleaning process, the gap between the upper pulverizing mill 31 and the lower pulverizing mill 32 is narrowed. You may comprise so that it may discharge | emit while controlling so that the space | interval of the upper crushed mill 31 and the lower crushed mill 32 may be expanded or narrowed in the whole cleaning process.

[Control operation]
The operation | movement by the said control apparatus 100 is demonstrated based on the flowchart shown in FIG.
[1] When the power is turned on, the control device 100 operates to determine whether or not the pulverization process by the pulverization control unit 103 or the cleaning process by the cleaning control unit 104 is performed, and in the pulverization process or the cleaning process. If it is in operation, the status indicator 4a is turned on (steps 1 and 3).
[2] If it is not in operation in the crushing process or the cleaning process, it is determined whether or not a predetermined amount of coins has been inserted based on a detection signal from the coin detector 3, and a predetermined amount of coins has been inserted. If not, the state where the state indicator lamp 4a remains lit is maintained (steps 2 and 3).
[3] When a predetermined amount of coins is inserted, it is determined whether or not an object to be processed remains in the receiving port hopper 12 based on a detection signal from the residue detector 18, and if it remains. Then, the residue indicator lamp 4e is turned on, the first electric motor 51 is driven to pulverize the residue, and then the suction fan 63 is driven to perform the cleaning process (steps 4 to 7).
[4] If no workpiece remains in the receiving hopper 12, the start indicator lamp 4 b indicating that the grain can be input from the grain input 11 </ b> A is turned on, and the opening / closing lid 11 </ b> B by the lock mechanism 6 is turned on. Is unlocked (step 4, step 8, step 9).
[5] Based on the detection signal from the input detector 17 provided in the input port hopper 11, whether or not the object to be processed has been input, and the input object to be processed is the object to be milled. Judge whether there is. If it is not inserted, it waits for input, and when it is determined that the input processed object is not the object to be milled, the different material indicator lamp 4d is turned on, and the inserted coin is changed to the change return port. Return to 3B and return to step 1 (steps 10 to 13).
In this state, by pulling out the different material take-out shutter 15 by human operation, the object to be processed in the inlet hopper 11 can be discharged into the different material hopper 13. Further, the object to be processed can be taken out together with the different material hopper 13 by putting the finger on the finger hooking portion 13 a of the different material hopper 13 and pulling it out.

[6] Based on the detection signal from the input detector 17 provided in the input port hopper 11, when it is determined that the input processing object is the processing target to be milled, the particle size is selected. The particle size of the object to be processed selected by the switch 5 is detected, the second electric motor 52 is driven so that the pulverization with the selected particle size is performed, and the lower pulverizing mill 32 is moved to a predetermined height position. (Step 14).
[7] Next, whether or not the opening / closing lid 11B is closed by an artificial operation is detected by the insertion port switch sw, and if it is not closed, the process waits in a state where the particle size can be changed by the particle size selection switch 5. When the closing port sw detects that the opening / closing lid 11B is closed, the locking operation solenoid 7 is operated to lock the locking mechanism 6, and the opening / closing solenoid 8 opens the outlet shutter 16 of the closing port hopper 11, The workpiece is caused to flow into the receiving hopper 12 side (steps 15 to 17).

[8] When the workpiece is supplied to the receiving hopper 12, the first electric motor 51 and the blower 38 of the cooling device 35 are driven, and the crushing process in the crushing unit 20 and the refining unit 30 is performed. When the pulverization process is performed for a predetermined time, the driving of the first electric motor 51 is stopped, and the end indicator lamp 4f that notifies the end of the pulverization process is turned on (steps 18 to 20).
In this state, when the take-out operation plate 42 is pulled out to the open position by human operation, the object to be processed stored in the powder collection unit 41 can be dropped and supplied to the take-out recess 43 below.

[9] Next, the removal operation plate 42 is returned to the closed position, and it is detected whether or not the cleaning start switch 9 is turned on. When the turning operation is detected, the first electric motor 51 and the second electric motor 51 are detected. The motor 52 and the suction fan 63 are driven to start the cleaning process with the cleaning cleaner 60 (steps 21 and 22).
[10] The drive time of the first electric motor 51 and the suction fan 63 in the cleaning process is a predetermined time set in advance by the cleaning control means 104. After the predetermined time has elapsed, the cleaning process is terminated, the power is turned off, etc. If no end condition is input, control returns to step 1 to continue control (steps 23 and 24).
