You can do it. Although not shown, the measurement result is displayed by an appropriate display device.

The material tank 3 has an inlet 31 for the mortar material in the upper part and an outlet 32 in the lower end, and the bottom of the material tank is inclined toward the outlet 32. A material supply means 33 such as a screw conveyor or a spring feeder is connected to the discharge port 32, and is operated by turning on a switch (not shown) to continuously discharge the material discharged from the discharge port 32. Then, it is charged into the mixer from the charging port 12 of the mixer 1. Alternatively, the material tank 3 may be arranged above the mixer 1 and an outlet having an opening / closing device may be provided below the material tank 3 so that the material is put into the mixer 1 by natural fall. In this case, the outlet serves as the material supply means 33, and the switchgear serves as the switch.

The water tank 4 has a mortar water inlet 41 and a water supply means 42 such as a pump in the upper part thereof. This water supply means 42 operates by turning on a switch (not shown), pumps up the water in the water tank 4, and feeds it into the mixer from the input port 12 of the mixer 1 via the pipe 43. In the figure, 44 indicates a check valve for preventing backflow of water, and 45 indicates a cleaning nozzle for cleaning this device and its surroundings by using this water. The water tank 4 may be arranged above the mixer 1 and an outlet having an opening / closing valve may be provided below the water tank 4 so that the material is put into the mixer 1 by spontaneous fall. In this case, the outlet serves as the water supply means 34 and the on-off valve serves as the switch.

The above is the basic configuration, and the mortar discharged from the discharge port 13 of the mixer 1 may be carried to a required place in an appropriate container or the like, or the discharge port 13 is connected to a mortar pump. The pump may discharge the gas to a required location, but in this embodiment, the following configuration is adopted.

The discharge port 13 of the mixer 1 is connected to the input port 51 of the secondary stirring means 5. The secondary stirring means 5 may be a batch type or a continuous type similar to the above mixer 1, and the mortar material and water stirred by the mixer 1 are stirred to a better condition. To do. A pump 6 for mortar is connected to the secondary stirring means 5 so that the well kneaded mortar can be discharged from the pump 6 to a necessary place.

The mixer for mortar and the like can be manually operated by the above-mentioned configuration, but in this embodiment, the process from metering to discharge is automatically controlled, as shown in FIG. Thus, the setting means 103 including the input means 101 and the storage means 102 and the control means 104 are provided. The control means 104 includes a water instructing means 105, a material instructing means 106, a mixer instructing means 107, and a secondary stirring instructing means 108. These instructing means are the water supply means 42 and the material supply means 33. , And the mixer 1 and the secondary stirring means 5, respectively. Further, the weighing means 2 is connected to the control means 104, and sequentially transmits the weighing result to the control means.

The setting means 103 is for setting the blending amount of the mortar material and water, and the input amount of the mortar material (for example, 10 kg) and the input amount of water (for example, 10 kg) are input from the input means 101. It is stored in the storage means 102. Incidentally, the mixing ratio of the mortar material and water (for example, 50:50) may be stored in advance, and only the input amount (for example, 10 kg) of one of the mortar material and water may be input, or the total amount may be input. You may make it input only a quantity (for example, 20 kg).

The control means 104 automatically measures the amount based on the set numerical value and performs secondary stirring. First, the stirring blade of the mixer 1 is rotated via the mixer instruction means 107. At the same time, the water supply means 42 is operated via the water instruction means 105 to supply water into the mixer 1.

When the measurement result sent from the measuring means 2 to the control means reaches a set amount (for example, 10 kg of water), the control means 104 instructs the water supply means 42 via the water instruction means 105 to stop the operation. At the same time, the material supplying means 33 is operated via the material indicating means 106 to supply the mortar material into the mixer 1. Meanwhile, the mixer 1 continues to perform the stirring work.

When the weighing result sent from the weighing means 2 to the control means reaches a set amount (for example, 20 kg of water and 10 kg of material in total 20 kg), the control means 104 causes the material supply means 33 via the material indicating means 106. To stop the operation. After a predetermined time elapses after this material supply is stopped, the control means 104 opens the above-mentioned on-off valve 14 of the mixer 1 through the mixer instructing means 107 to discharge the stirred mortar from the discharge port 13. In addition, the secondary stirring means 5 is operated via the secondary stirring instruction means 108. It should be noted that this predetermined time is a time required to stir the supplied water and the material, and may be calculated by the control means from the set amounts of the supplied water and the material, or The operator may directly set the setting means 103. Furthermore, a separate timer may be provided and the control means may control only the start of stirring of the mixer 1.

When the weighing result sent from the weighing means 2 to the control means returns to 0, the control means 104 closes the on-off valve 14 of the mixer 1 via the mixer instructing means 107. As a result, the stirring work in the mixer 1 is completed and the rotation of the stirring blades of the mixer 1 is stopped. However, when stirring is continued, the next water is added without stopping the rotation of the stirring blades of the mixer 1. You may return.

The secondary stirring means 5 continuously stirs and stops the stirring after a lapse of a predetermined time. Note that this predetermined time may also be calculated by the control means from the set amounts of water and material input, as in the stirring of the mixer 1, or may be set directly by the operator by the setting means 103. You may Furthermore, a separate timer may be provided and the control means may control only the start of stirring of the secondary stirring means. After the completion of the secondary stirring, the mortar is discharged by the pump 6 to a necessary place. The operation of the pump 6 can also be controlled by the control means, but it is actually convenient to separate it from the control means because of problems such as preparation of the discharge destination. This secondary stirring is auxiliary, and the discharge from the pump 6 may be performed while the secondary stirring means 5 is operating.

The secondary stirring means 5 may be a batch type, or may be a type that continuously stirs and discharges. However, as in the above-described embodiment, the same capacity as the mixer 1 is used. If a batch-type secondary stirring means having is adopted, after the stirring of the mixer 1 is completed, the mortar is transferred to the secondary stirring means 5, and the mixer 1 can immediately stir the next material, It is advantageous in that substantially continuous operation is possible. It should be noted that it is possible to operate manually without using the control means as described above. In that case, while the operator is watching the display of the measurement result of the measurement means 2, the water supply means and the material supply are supplied. And the means may be controlled.
