4, 105, each powder tank 101, 1
Whether each of the tanks 02, 103, 104, and 105 was full was determined by visual inspection by an operator, and each of the powder tanks 101, 102, 103, 104, and 10 was checked.
5 also confirmed that the amount of the residual powder charged into the powder tank 5 was determined by using a predetermined tool for each of the powder tanks 101, 102, 103, 104, and 105. When the powder is discharged from the mixers 102, 103, 104, and 105 into the mixing device 111, for example, voids are generated in the third powder tank 103 and the powder in the powder tank 103 is not discharged into the mixing device 111. Is confirmed by visually observing the window formed in the mixing device 111.
An extremely large number of workers are required in the steps from the step of charging into 2, 103, 104 and 105 to the step of mixing predetermined powder. Also, as described above, whether or not each process is proceeding smoothly is visually checked by many workers, etc., so that the discovery of troubles occurring in each process is delayed, and accurate mixing is not performed. not only many variations in done without quality occurs, an extreme hazard powder that such can not be shipped at all in the mixing device 111.

That is, there are many types of powders to be shipped at the mill, and these powders are not necessarily the shipment amount of one truck T. For example, the powders put into the first powder tank 101 And the first powder mixed with the powder charged into the third powder tank 103 and the powder charged into the fifth powder tank 105 needs to be shipped for three trucks. 2 powder tank 1
In the case where the second powder mixed with the powder charged into the second powder 02 and the powder charged into the third powder tank 103 must be shipped for five trucks, the conventional powder is used. In the mixed shipping apparatus 100, the second powder cannot be shipped unless the first powder is first shipped for three trucks T, and the shipping efficiency is extremely low.

1a is driven and controlled. The central processing unit 83 includes first to third monitors 87,
88, 89 and a printer 90, and the first to third monitors 87, 88, 89 drive the respective powder amount measuring devices 9 to measure the A to E powder tanks 11, 12,. The amount of the powder, the shipping elapsed time, the shipping completion time, and the like can be confirmed in the monitoring room, the vicinity of the shipping truck T, or the like, for example, in 13, 14, and 15;
Further, the printer 90 can confirm the amount of powder and the like shipped by the first shipping truck T, for example.

Hereinafter, the operation of the present apparatus 1 having the above configuration will be described in detail. First, with reference to FIG. 8, the operation when the powder P is charged into a predetermined powder tank (for example, the C powder tank 13) of the A to E powder tanks 11, 12, 13, 14, and 15. This will be described in detail.
First, in step st1, the input operation unit 86 inputs the number of the predetermined (C) powder tank 13 into which the powder P is to be charged. In addition, the powder P is sequentially stored in a plurality of powder tanks.
, The numbers of a plurality of powder tanks are input. When the input of these powder tank numbers is completed, in step st2, the suction fan 34 connected to the powder tank 13 via the pipe 34a starts driving. At step st3, it is determined whether or not the powder tank 13 into which the powder P is to be charged is full. If the powder tank 13 is full, the operation is stopped. If not, the charging valve 5c is opened at step st4. Is done. The determination as to whether or not the powder tank 13 is full is made by the upper limit level detecting device 8 and the powder amount measuring device 9. In step st5, since the injection valve 5c may not be completely opened, it is checked whether the injection valve 5c is open. If the injection valve 5c is open, the mixing valve that has been driven up to that time in step st6 is checked. Machine 33
Is temporarily stopped, and the dry air valve 37a is closed in step st7. This is to prevent the powder P from entering the dehumidifier 37 by charging the powder P while the dry air valve 37a is open. Then, when the dry air valve 37a is closed, in steps st8, st9, and st10, the mixer 33, the blower 27a, and the rotary valve 27 are set.
Are driven, and the powder P is charged into the C powder tank 13 through the third pipe line 5 by these drives. In step st11, the upper limit level detecting device 8 detects whether or not the powder tank 13 is full. If the powder tank 13 is not full, the charging of the powder P is continued. In, it is determined whether or not there is a reservation for the powder tank to be charged next. If there is a next reservation, the process returns to step st2 and repeats the operation up to step st10. If there is no next reservation, the suction fan 34, the blower 27a, the mixer 33, and the third rotary valve 27 are set to steps st13, 14, 1 respectively.
At step st17, the drying air valve 37a is opened, and the drying air from the dehumidifying device 37 flows into the C powder tank 13 through the third conduit 5, The charging of the powder P is completed. Therefore, according to the present apparatus 1, the powder P passes through each of the pipes 3, 4, 5, 6, and 7, and each of the powder tanks 11, 12, 1
Since the dry air is always introduced into the pipes 3, 4, 5, 6, 7 except when the air is introduced into the insides 3, 14, 15 even when the outside air is extremely low. Line 3,
There is no dew condensation on the inner peripheral surface of 4, 5, 6, 7
Therefore, the risk that the pipes 3, 4, 5, 6, and 7 are clogged with the powder P and that the powder P generates mold can be effectively prevented. Also, the powder tanks 11, 12, 13, 14, 1
Whether or not the powder P is full during the charging of the powder P into the inside 5 is detected by the upper limit level detection device 8 and the suction fan 34, the blowers 25a, 26a,
27a, 28a, 29a, the mixer 33, and the rotary valves 25, 26, 27, 28, 29 are configured to automatically stop according to the detection result of the upper limit level detection device 8, so that they are the same as the conventional one. It is not necessary for the operator to visually check whether the powder tanks 11, 12, 13, 14, 15 are full.

Next, each of the powder tanks 11, 12, 13, 1
The operation of measuring the amount of the powder P charged into the insides 4 and 15 will be described in detail with reference to FIG. First,
Oite to step st20, the input operation unit 86 a predetermined flour tanks 11, 12 and 13 to be measured amount of powder by,
Numbers 14 and 15 are set. Then, step st2
In step 1, it is determined whether the powder P is currently being charged into the set powder tank 12, for example, B. If the powder P is being charged, the measurement is stopped. In step st22, the amount of powder is measured. Whether or not the powder P is being charged is determined by, for example, whether or not the second rotary valve 26 is being driven. Further, the powder amount is measured by the powder amount measuring device 9 described in detail above. When the measurement for each powder tank is completed in step st23, it is calculated by the central processing unit 83 in step st24, and in step st25. Then, while being displayed on the first to third monitors 87, 88, and 89, it is output to the printer 90 in step st26, and the processing ends. When the measurement of the powder amount is completed as described above, the powder amount measuring device 9 drives the motor (not shown) to wind the rope 48 onto the winding reel 46 and return to the initial position.

Next, each of the powder tanks 11, 12, 13, 1

13, 15), the number of the plurality of powder tanks (three in this case), the discharge amount of the powder P discharged from each of the powder tanks 11, 13, 15 and each of the powder tanks 1
The discharge time of the powder P from 1, 13, and 15 is set, respectively. It should be noted that the discharge time of the powder P is set in step st33 when the discharge amount of the powder P is not accurately measured by the powder amount measuring device 9 described later, and the accurate discharge amount is detected based on the discharge time. To try.
Then, these set values are transmitted to the central processing unit 83 in step St34, and then in step st35, the powder P is discharged into the powder tanks 11, 13, and 15 of A, C and E, for example. It is determined whether or not P is in the state of being inserted. If the state is being inserted, the subsequent operation is stopped.
By operating a button (not shown) for starting the measurement of the amount of powder in each of the powder tanks 11, 13, and 15 in step 6, these powder tanks 1 and 2 are operated in step st 37.
The measurement of the amount of powder in 1, 13, and 15 is started. And
In step st38, each of these powder tanks 11, 13,
It is determined whether or not each of the powders 15 is filled with an amount of powder P necessary for shipment. At this time, if a predetermined amount of the powder P is not filled in any of the powder tanks, the shipment is stopped, and the powder is stored in the powder tank as described with reference to FIG. The body P is thrown. If a predetermined amount of the powder P is filled in all the powder tanks 11, 13, and 15, in step st39, it is determined whether or not the discharge pipes 22a and 23a are set in the openings of the shipping truck T. Judge. These discharge pipes 22a,
If 23a is not set, step st3

The rotation speed of each of the first, third, and fifth discharge drive motors 17a, 19a, and 21a is adjusted via a speed control device (inverter) 84 connected to the central processing unit 83. Then, as shown in FIG. 11, during shipping (step st45), the above-described porosity detection device 10 detects whether or not porosity has occurred in any of the A, C, and E powder tanks 11, 13, and 15. (Steps
t46) If no void has occurred, step st
Predetermined amount mixed powder P whether shipped is determined at 47. This determination is made by detecting, by the central processing unit 83, whether or not the shipping truck T on the weighing platform 81 connected to the weighing device 85 has a predetermined weight. If the predetermined amount has not been reached, the process returns to step st45 to continue shipping. Then, when a predetermined amount of the mixed powder P is shipped, and when it is detected in step st46 that a pore has occurred, the central processing unit 83 (step st4)

Next, in step st53, it is determined whether or not the powder P to be shipped to the next shipping truck T is also the same powder P as the powder P. Returning to step st34 shown in FIG. 10, if it is another powder P, it is determined in step st54 whether the powder P shipped this time remains in the agitator conveyor 16 or not. If the powder P shipped this time remains in the agitator conveyor 16, a return operation described in detail later is performed (step st5).
5) The powder P mixed in the agitator conveyer 16 is put into the powder tank 14, for example D, other than the powder tanks 11, 13, 15 from which the powder P has been discharged this time. When the same powder P as the current powder P is shipped again after the powder P to be shipped to the factory, the powder tanks A, C, and E in the step st30.
Not only 1, 13, 15 but also the D powder tank 14 is set. If no powder P remains in the agitator conveyor 16, the shipment is completed (step st56).

Finally, a case of performing a return operation using the present apparatus 1 will be described with reference to FIGS. Here, the return operation means that a plurality of powders P
Means that the mixed powder P is put into another powder tank instead of being shipped immediately after mixing. By this return operation, the powder P in the other powder tank is shipped to the next shipping truck T only from the another powder tank, or the powder P in the other powder tank is mixed with the powder P in the other powder tank. Work such as shipping as another powder P can be made possible. When performing this return operation, first, as shown in FIG. 12, steps st60, 61, 62, 6 are performed.

[0024] Thus, the engagement Ru equipment 1 in the above embodiment, the first to fifth conduit 3,4,5,6,7, dehumidification each device 35,36,37,38,39 Is connected, and the dry air from the dehumidifiers 35, 36, 37, 38, 39 can be blown into the pipes 3, 4, 5, 6, 7, so that the pipes 3, 4, 5, 5 can be blown. , 6, 7, the humidity contained in the air in the conduits 3, 4, 5, 6, 7 is reduced by the blowing of dry air, whereby the pipe P No dew condensation occurs on the inner peripheral surfaces of the roads 3, 4, 5, 6, and 7. Accordingly, it is possible to effectively prevent the pipes 3, 4, 5, 6, and 7 from being clogged or mold from being generated in the powder P due to the occurrence of such dew condensation. Thus, labor such as wearing clothes can be effectively saved. In the above embodiment,
Pipes 3, 4, 5, and 5 provided for charging the powder P
What 6,7 in dry air is adapted to flow has been described as an example, but other the return conduit 76,77,7
It may be connected to a dehumidifier (not shown) so that dry air flows into 8, 79 and 80.

Further, in the powder mixing and shipping apparatus 1 according to the above embodiment, the powder tanks A, E, 12, 13, 13, 14,
15 includes an upper limit level detecting device 8 for detecting that the powder P charged into the powder tanks 11, 12, 13, 14, 15 is full, and a powder tank 11, 12, 13, 13, 1
And a powder amount measuring device 9 for measuring the amount of powder in each of the powder tanks 11, 12, 13, 14 via the pipes 3, 4, 5, 6, 7. , 15 do not need to be visually checked by an operator to determine whether or not the powder P is full. Is the powder tank 11,1
Since it is detected that a predetermined amount is discharged from 2, 13, 14, 15, for example, the powder tanks 11, 12, 13, 14,
The emptying of the powder P in 15 can also be confirmed very easily and reliably without visual inspection by an operator.
In the powder mixing and shipping apparatus 1 according to the above-described embodiment, the rope 47 having the weight 47 fixed to the tip is driven by a motor to take up the weight 47 from the take-up reel 46 into the powder tank 11.
An apparatus for feeding the powder P put into the 12, 13, 14, 15 until it comes into contact with the powder P and measuring the amount of powder by measuring the feeding length has been illustrated and described. Powder tanks 11, 12, 13, 14, 15
Any other configuration may be used as long as the amount of the powder inside can be measured. Similarly, in the powder mixing and shipping apparatus 1, voids were generated at the lower ends of the powder tanks 11, 12, 13, 14, 15 at the lower ends of the powder tanks 11, 12, 13, 14, 15. Since the porosity detection device 10 is provided to detect the occurrence of porosity, the occurrence of porosity in the powder tank can be confirmed earlier and more reliably than in the case of visual observation by an operator. In addition, in the device 1 according to the above-described embodiment, the pore detection device 10 is described using the pore detection device 10 using an optical sensor having a light emitting unit and a light receiving unit as an example. In addition, a tongue piece 93 formed of a conductive material, having a base end fixed to the inner wall 91a of the powder tank 91 from which the powder P is gradually discharged, and one end provided with one connection terminal 92, Inner wall 9 of powder tank 91

3 and the other connection terminal 94 may be a pore detection device 96 connected to the central processing unit 83, respectively.
According to the pore detection device 96 having such a configuration, when the powder P is properly discharged from the powder tank 91, the one connection terminal 92 and the other connection terminal 94 are in contact with each other, and In the event that a pour occurs in the powder tank 91,
Since the one connection terminal 92 and the other connection terminal 94 are separated from each other by the elastic force of the elastic body 95, it is possible to detect the occurrence of voids in the powder tank 91. Therefore, in the present invention, the porosity detection device 96 may be used in place of the porosity detection device 10.

In the powder mixing and shipping apparatus 1, the number of the specific powder tank into which the powder P to be mixed is input is determined by the central processing unit 83 which is a control means and has a storage means therein. and emissions of each of the powder P to be mixed is stored, shipments are powder P of the amount the output signal from the meter 85 for measuring the (amount of powder P shipped in shipping truck T) Controls the driving of the first, third and fifth discharge driving motors 17a, 19a and 21a constituting the first, third, and fifth discharging devices 17, 19, and 21, for example, for shipping. When shipping the first mixed powder having the total shipment amount of three trucks T and the second mixed powder having the total shipment amount of two trucks, the first mixed powder After being shipped by the first shipping truck T, the second Different kinds of mixed powders are continuously fed, for example, the mixed powder is shipped by a first shipping truck T, and then the first mixed powder is shipped by a second shipping truck T. Can be shipped. Also,
The central processing unit 83, which is a control unit, is provided with first, third, and fifth discharge driving motors constituting the discharge devices 17, 19, and 21 when a hole is generated by the hole detection unit 10 (96). 17a, 19a, and 21a are all stopped so that, for example, when it is necessary to mix three types of powder P at a predetermined ratio and amount before shipping, When a porosity occurs in a tank (for example, the E powder tank 15), not only the discharge device 21 corresponding to the powder tank 15 in which the porosity has occurred, but also the other discharge devices 17 and 19 are stopped. Therefore, it is possible to effectively avoid the risk of producing and shipping a mixed powder in which only the specific powder P is not mixed.

Further, in the powder mixing and shipping apparatus 1 according to this embodiment, as described above, the powder P mixed in the agitator conveyor 16 is mixed with the powder tanks A, E,
Since it is configured to be able to be charged into a predetermined powder tank among 13, 14, and 15 (configured to be able to perform a return operation), for example, A, C, and E powder tanks 11 , 13 and 15 can be mixed and charged into the D powder tank 14 so that the next shipment can be made only from the D powder tank 14. Alternatively, the powder (mixed powder) charged into the D powder tank 14 by the return operation is mixed with, for example, the powder P charged into the second powder tank 12 by the agitator conveyor 16. Can also be shipped.

As described above, according to the powder mixing and shipping apparatus 1 according to the above embodiment, the input, mixing and shipping operations of the powder P which could not be performed unless a large number of workers were required in the past. Can be carried out easily, quickly and reliably with a very small number of people, especially when a specific mixed powder mixture must be shipped on multiple shipping trucks, and a large number of such powder Even when it comes to types,
The inconvenience that other types of mixed powders cannot be shipped until all the mixed powders of a specific type are shipped by a plurality of shipping trucks can be effectively eliminated, and as a result, the efficiency is extremely high. Can be shipped well.
