Description

  The present invention automatically controls the loading gate at the lower end of the concrete hopper so that the flow of the ready-mixed concrete becomes appropriate when the ready-mixed concrete manufactured by the concrete manufacturing facility is loaded from the concrete hopper onto the track agitator (mixer truck). The present invention relates to a method and apparatus for controlling a concrete hopper loading gate.

  In the case of performing concrete placing work, generally, the ready-mixed concrete manufactured by the concrete manufacturing facility is loaded on a truck agitator, so-called a mixer car, and transported to the site.

  As shown in FIG. 4, the apparatus for loading the ready-mixed concrete into the mixer truck in the concrete manufacturing facility as described above is a batcher plant mixer 2 for kneading ready-mixed concrete 1 and discharged from the mixer 2. A concrete hopper (primary hopper) 4 for receiving the ready-mixed concrete 1 and guiding it to the mixer truck 3 is disposed at a required height position so that the mixer truck 3 can enter below the concrete hopper 4. There is a configuration in which the structure 5 is supported by the gantry 5, and a configuration in which the lower end discharge port 4 a of the concrete hopper 4 is provided with a loading gate (lid) 6 that can be freely opened and closed. Thereby, the mixer truck 3 is made to enter below the concrete hopper 4, and the receiving hopper (receiving port hopper) 3a of the mixing truck 3 is arranged to be located directly below the lower end discharge port 4a of the concrete hopper 4. After that, the loading gate 6 of the concrete hopper 4 receiving the ready-mixed concrete 1 kneaded in the mixer 2 is opened, and the ready-mixed concrete 1 in the concrete hopper 4 passes through the loading gate 6 and the mixer truck 3 The ready-mixed concrete 1 is loaded onto the mixer truck 3 by flowing down to the receiving hopper 3a (see, for example, Patent Document 1).

  By the way, in general, the lower end side of the receiving hopper 3 a of the mixer truck 3 is narrower than the lower end discharge port 4 a of the concrete hopper 4. In addition, since the ready-mixed concrete 1 manufactured by the ready-mixed concrete manufacturing equipment has slumps and flows determined for each kind such as soft kneading, solid kneading, mortar kneading, etc., the fluidity changes for each kind. For this reason, for example, when loading the ready-mixed concrete 1 having a relatively small slump and low fluidity onto the mixer truck 3, the opening degree of the loading gate 6 of the concrete hopper 4 is suddenly increased. And the flow speed of the ready-mixed concrete 1 flowing down from the concrete hopper 4 to the receiving hopper 3a of the mixer truck 3 exceeds the speed at which the ready-mixed concrete 1 of the receiving hopper 3a is received in the mixer drum of the mixer truck 3. There is a possibility that the ready-mixed concrete 1 overflows from the receiving hopper 3a of the mixer truck 3.

  Therefore, conventionally, when loading the ready-mixed concrete 1 into the mixer truck 3, an operator (not shown) of the ready-mixed concrete 1 flowing down from the concrete hopper 4 to the receiving hopper 3 a of the mixer truck 3. The flow-down state and the state that the ready-mixed concrete 1 that has flowed down rebounds from the receiving hopper 3a side of the mixer truck 3 are directly observed through the gap between the lower end of the loading gate 6 and the upper end portion of the receiving hopper 3a of the mixer truck 3. Alternatively, the video taken by a camera or the like is monitored, and the opening operation for increasing the opening degree of the loading gate 6 according to the flow-down state or the rebound state of the ready-mixed concrete 1 and the opening degree are reduced (reduced). ) A combination of a closing operation and a stopping state (hereinafter referred to as a stopping operation) in which both the opening and closing operations of the loading gate 6 are stopped to maintain the opening degree of the loading gate 6 By manually controlling the opening of the loading gate 6, the loading of the ready-mixed concrete 1 from the concrete hopper 4 to the mixer truck 3 is prevented, and the overflow of the ready-mixed concrete 1 from the receiving hopper 3 a of the mixer truck 3 is prevented. However, we try to make it happen as quickly as possible.

  As described above, when loading the ready-mixed concrete 1 into the mixer truck 3 from the concrete hopper 4, the ready-mixed concrete flows down so that the ready-mixed concrete 1 can be prevented from overflowing from the receiving hopper 3a of the mixer truck 3. Skill is required to manually control the opening, closing, and stopping operations of the loading gate 6 while monitoring the state and the rebound state. Therefore, there is a problem that the number of personnel that can be operated is limited to skilled operators.

  Therefore, in order to enable anyone to easily load the ready-mixed concrete 1 from the concrete hopper 4 into the mixer truck 3, the loading gate 6 is automatically opened, closed, and stopped. It is desired to be able to control, and at present, the operation time of the opening operation, the stopping operation, and the closing operation of the loading gate 6 is arbitrarily set on the control panel (not shown) of the loading gate 6. A timer that can be set to the above-mentioned time is provided, and the opening, stopping, and closing operation times of the loading gate 6 are respectively input to the timer. For example, when the loading gate 6 is opened, the loading gate 6 Based on the set time set by the above timer by arbitrarily setting, such as repeating the opening operation and stopping operation for 2 seconds each time so that the opening can be increased in steps. Gate Open, closed, it is believed be automatically performed each operation of stopping.

JP 11-245220 A

  However, as described above, when the loading operation of the ready-mixed concrete 1 from the concrete hopper 4 is performed, the operation time of the opening operation, the stopping operation, and the closing operation of the loading gate 6 is arbitrarily set by a timer. If an error occurs in the total loading time determined by the opening operation time, the stopping operation time, and the closing operation time of the loading gate 6 set by the timer, the ready-mixed concrete 1 to be loaded into the mixer truck 3 is essentially a concrete hopper. There is a possibility that it will remain in 4.

  Even when the loading gate 6 is opened, stopped, or closed based on the time setting in the timer, the timing of each operation set in the timer is loaded into the mixer vehicle 3. If it is not suitable for the slump or flow of the ready-mixed concrete 1 to perform, the ready-mixed concrete 1 flowing down from the concrete hopper 4 may overflow from the receiving hopper 3a of the mixer truck 3.

  Therefore, even when the opening operation, the stopping operation, and the closing operation of the loading gate 6 are automated using the timer as described above, the time setting of each operation in the timer is set by experienced operators. Based on the slump and flow of the ready-mixed concrete 1, it is necessary to perform the overflow of the ready-mixed concrete 1 from the receiving hopper 3a of the mixer truck 3 even if the skilled operator sets the time. The reality is that it cannot be prevented.

  One method for automating the opening operation, the stopping operation, and the closing operation of the loading gate 6 of the concrete hopper 4 includes the staying state of the ready-mixed concrete 1 in the receiving hopper 3a of the mixer truck 3, A sensor (not shown) for detecting the acceptance state of the ready-mixed concrete 1 from the receiving hopper 3a into the mixer drum is provided, and the loading and unloading operation of the loading gate 6 of the concrete hopper 4 is performed based on the detection result of the sensor. It is conceivable to control the closing operation. In this case, it is necessary to equip all the mixer trucks 3 with sensors, or control the loading gates 6 based on the detection results detected by the sensors on the mixer truck 3 side. There is a problem that the number of equipment increases and the apparatus becomes complicated and the cost increases, for example, an apparatus for sending to the board side is required.

  Therefore, the present invention enables the quick concrete loading operation from the concrete hopper to the mixer truck to be carried out quickly without the need for sensors and while preventing the overflow of the ready concrete from the receiving hopper of the mixer truck. An object of the present invention is to provide a method and an apparatus for controlling a concrete hopper loading gate that can automatically control the loading gate of the concrete hopper.

  In order to solve the above-mentioned problems, the present invention provides a loading gate for manually controlling a loading gate of a concrete hopper and loading the ready-mixed concrete in the concrete hopper into the mixer truck through the loading gate. Time series operation data related to the sequence and operation time of each of the opening, closing, and stopping operations, and then loading the ready-mixed concrete, reading the stored time series operation data, A concrete hopper loading gate control method for causing the loading gate to be opened, closed, and stopped according to the read time-series operation data, and the concrete hopper loading gate opening operation, A function for manually controlling each operation of opening, closing, and stopping of the loading gate on a control panel capable of issuing a command for performing a closing operation and a stopping operation; and Time series operation of the sequence of opening, closing, and stopping of the loading gate when loading concrete into the mixer truck through the loading gate by manual control of the loading gate A function for storing data, a function for reading the stored time-series operation data, and a function for automatically controlling each operation of opening, closing, and stopping the loading gate according to the read time-series data. A concrete hopper control device having the configuration as described above is provided.

  In addition, the loading gate time-series operation data in the above-described configuration is stored and read out for each section obtained by dividing the slump or flow of ready-mixed concrete by a required numerical width.

According to the concrete hopper loading gate control method and apparatus of the present invention, the following excellent effects are exhibited.

Is controlled by a function for manually controlling the opening, closing, and stopping operations of the loading gate and a manual control of the loading gate. A function for storing time-series operation data of the sequence of opening, closing, and stopping operations of the loading gate when loading the ready concrete in the cleat hopper into the mixer truck through the loading gate; , Having a function of reading the stored time-series operation data and automatically controlling each operation of opening, closing, and stopping the loading gate according to the read time-series data Since it is a control device for the concrete hopper loading gate, once the skilled operator performs manual control of the loading gate, the subsequent concrete loading work is the same as the manual control of the loading gate by the skilled operator. It is possible to automatically control the loading gate of the concrete hopper according to the operation sequence and operation time. Therefore, it is possible to prevent the ready-mixed concrete flowing down from the concrete hopper through the loading gate to the mixer truck from overflowing from the receiving hopper of the mixer truck, and the loading work can be carried out quickly and the time required for the loading work. Can be shortened.
(2) The time series operation data of loading gates are stored and read out for each section obtained by dividing the slump or flow of ready-mixed concrete by the required numerical width, so that the slump and flow are different. Automatic control of concrete hopper loading gates can be appropriately handled for ready-mixed concrete varieties.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 to FIG. 3 show an embodiment of a method and apparatus for controlling a concrete hopper loading gate according to the present invention. In the loading apparatus for the ready-mixed concrete in the concrete production facility shown in FIG. An external control device 7 for opening and closing the loading gate 6 having the same configuration as that of the loading gate 6 of the concrete hopper 4 is provided, and further, the opening and closing operation of the loading gate 6 with respect to the external control device 7 is performed. A control panel 8 is provided that issues commands for performing an operation and a stop operation, and controls the opening, closing, and stop operations of the loading gate 6 via the external control device 7.

  The control panel 8 has a function of manually controlling the opening operation, the closing operation, and the stopping operation of the loading gate 6 and the concrete hopper by manual control of the opening operation, the closing operation, and the stopping operation of the loading gate 6 as described above. The above loading operation was carried out in accordance with the time series of the opening, closing, and stopping operations of the loading gate 6 when loading the ready-mixed concrete into the mixer truck from the loading gate 6 through the loading gate 6. A function that can be stored in association with a slump or flow of ready-mixed concrete, and also a slump or flow corresponding to the slump or flow of ready-mixed concrete to be loaded when loading the ready-mixed concrete from the concrete hopper to the mixer truck. The loading gate at the time of loading work by manual control of the loading gate 6 previously memorized for the ready-mixed concrete 6 to read out the operation pattern along the time series of each of the opening, closing, and stopping operations, and to reproduce the opening, closing, and stopping operations of the loading gate 6 along the read operation pattern. It has a function capable of automatically controlling the loading gate 6.

  More specifically, the control panel 8 includes an automatic control mode switch 9 that switches the control mode of the loading gate 6 from manual control to automatic control by an ON operation. Further, under the condition that the automatic control mode switch 9 is in the OFF state, the opening switch 10 for opening the loading gate 6 in the manual control mode is ON only during the ON operation. A closing switch 11 for closing the loading gate 6 in the manual control mode for a period of time, a teaching start / completion switch 12 for instructing the start and completion of teaching as will be described later, A slump / flow selection switch 13 for designating (instructing) concrete slump or flow is provided, and each of the switches 9, 10, 11, 12, 13 is connected to the setting calculation control unit 14 is there. Even when the automatic control mode switch 9 is turned on, any one of the opening switch 10, the closing switch 11, the teaching start / end switch 12, and the slump / flow selection switch 13 is operated. Therefore, it is desirable to automatically turn off and automatically return to the manual control mode.

  Further, the control panel 8 includes a pattern distinction storage unit 15, a timer storage unit 16, an open monitoring timer 18 that monitors the opening operation of the loading gate 6 and measures the opening operation time, and closes the loading gate 6. The timer circuit unit 17 includes a closing monitoring timer 19 that monitors the operation and measures the closing operation time, and a stop monitoring timer 20 that monitors the stopping operation of the loading gate 6 and measures the stopping operation time. is there.

  When the automatic control mode switch 9 is in an OFF state (hereinafter referred to as a manual control mode), the setting calculation control unit 14 outputs a gate opening operation command while the open switch 10 is ON. The loading gate 6 can be opened to the external control device 7 to open the loading gate 6 via the external control device 7. Further, while the closing switch 11 is on, a gate closing operation command is issued to the external control device 7 so that the loading gate 6 can be closed via the external control device 7. It is. Further, when both the open switch 10 and the close switch 11 are in an OFF state, the transmission to the external control device 7 is stopped by the transmission of the gate open operation command and the gate close operation command, or actively stopped to the external control device 7. By issuing an operation command, the operation of the loading gate 6 by the external control device 7 is stopped, and the loading gate 6 can be stopped.

  When the teaching start / end switch 12 is instructed to start teaching in the manual control mode, the timer circuit unit 17 manually turns on the open switch 10 as described above, and the setting calculation control is performed. When the loading gate 6 is opened by a command from the unit 14, the duration of the opening operation is measured by the opening monitoring timer 18, and similarly, the closing switch 11 is turned on and the loading gate 6 is turned on. Is closed, the duration of the closing operation is measured by the closing monitoring timer 19, and the opening switch 10 and the closing switch 11 are both turned off to stop the operation of the loading gate 6. When the operation is stopped, the duration of the stop operation is measured by the stop monitoring timer 20, and the open monitoring timer 18, the closing monitoring timer 19 and the stop monitoring timer 20 are used. Open the loading gates 6 measured Re respectively, it closed, the measurement results of the operation time of the stop, are to be sequentially output to the timer memory unit 17.

  In the manual control mode as described above, the timer storage unit 17 opens and closes the loading gate 6 monitored by the timer circuit unit 17 by the open monitoring timer 18, the closing monitoring timer 19, and the stop monitoring timer 20. When the measurement result of each stop operation time is inputted, the measurement result of each opening, closing, and stop operation time of the loading gate 6 can be stored in time sequence in the order of the operation. Yes, the data about the sequence and operation time of the opening, closing, and stopping operations of the loading gate 6 stored along this time series (hereinafter referred to as the time-series operation data of the loading gate 6) is distinguished into patterns. It can be output to the storage unit 15.

  When the time series operation data of the loading gate 6 is input from the timer storage unit 16 in the manual control mode, the pattern distinction storage unit 15 converts the time series operation data of the loading gate 6 into the slump flow. The data can be stored in a state associated with a ready-made concrete slump or flow previously designated by the selection switch 13. In the slump / flow selection switch 13 and the pattern distinction storage unit 15, the slump and flow of ready-mixed concrete are divided into sections having a required numerical value range, and instructions by the slump / flow selection switch 13 are given for each section. It is desirable to associate the time series operation data of the loading gate 6 in the pattern distinction storage unit 15 with the slump and flow of ready-mixed concrete. In the above, the number of slumps and flows of ready-mixed concrete may be arbitrarily set, for example, 50 slumps and flows in total.

  Therefore, according to the control panel 8 having the above-described configuration, when loading the required variety of ready-mixed concrete from the concrete hopper to the mixer truck, the ready-mixed slump is loaded by the slump / flow selection switch 13. Alternatively, when the division corresponding to the flow is designated and the teaching start / end switch 12 is instructed to start teaching, the opening gate 10 and the closing switch 11 are manually turned on and off to open the loading gate 6. Opening and closing the loading gate 6 performed when loading the ready-mixed concrete by completing the loading work of the ready-mixed concrete into the mixer truck while manually controlling the closing and stopping operations. The above-mentioned pattern distinction memory stores the procedure along the time series of each operation of stop and the operation time of each operation. 15, it becomes possible to store in a state of association with sections of slump or flow corresponding to slump or flow of the fresh concrete was subjected to the loading operation.

  On the other hand, when the automatic control mode switch 9 is turned on, that is, in the automatic control mode of the loading gate 6, the setting calculation control unit 14 kneads the batcher plant from a batcher plant (not shown). When information on the slump or flow of ready-mixed concrete to be loaded into the mixer truck is input next, the slump or flow of the section corresponding to the slump or flow of ready-mixed concrete to be loaded is included. For the ready-mixed concrete, the time-series operation data of the loading gate 6 when the loading operation is performed by manually controlling the opening, closing, and stopping operations of the loading gate 6 previously is the pattern distinction storage unit. 15 can be read out. At the same time, in the timer storage unit 16, the operation time of each operation for reproducing the opening, closing, and stopping operations of the loading gate 6 along the time-series operation data read from the pattern distinction storage unit 15. Are counted by the operations of the open monitor timer 18, the close monitor timer 19 and the stop monitor timer 20 of the timer circuit unit 17 and can be output to the setting calculation control unit 14, respectively. As a result, the setting calculation control unit 14 performs the operation sequence and operation time of each of the opening, closing, and stopping operations of the loading gate 6 along the time-series operation data read from the pattern distinction storage unit 15. A command is given to the external control device 7, and the operation of the time-series operation data read from the pattern distinction storage unit 15 by the loading gate 6 is reproduced as it is.

  The external control device 7 for the loading gate 6 is provided in parallel on a supply line for supplying a working fluid to a fluid pressure cylinder (not shown) serving as a drive source for opening and closing the loading gate 6, for example. A command can be given to a certain solenoid valve 21 for gate opening operation and a solenoid valve 22 for gate closing operation, and the fluid pressure cylinder can be operated by operating the solenoid valve 21 for gate opening operation or the solenoid valve 22 for gate closing operation. The loading gate 6 is opened or closed by means of the above, and the supply of the working fluid to the fluid pressure cylinder is stopped by not issuing a command to both the solenoid valves 21 and 22. Thus, the loading gate 6 can be stopped.

  In the case of using the concrete hopper loading gate control apparatus of the present invention having the above-described configuration, after performing teaching according to the procedure shown in the flow in FIG. 2, the loading gate 6 according to the procedure shown in the flow in FIG. Let the automatic control of.

  That is, when teaching is performed, as shown in FIG. 2, first, the slump / flow selection switch 13 of the control panel 8 designates the slump or flow classification to which the ready-mixed concrete to be taught will belong (step 1: S1). ). Next, the teaching start is set by the teaching start / end switch (step 2: S2). As a result, the stop monitoring timer 20 of the timer circuit unit 17 for measuring the stop operation time of the loading gate 6 is started (step 3: S3).

  Next, when an experienced operator manually turns on the open switch 10 to perform loading work of ready-mixed concrete (step 4: S4), external control is performed based on the gate opening operation command from the setting calculation control unit 14. The opening operation of the loading gate 6 is started by the device 7 (step 5: S5). With the start of the opening operation of the loading gate 6, the operation of the stop monitoring timer 20 is stopped (step 6: S6), and the stop monitoring timer 20 starts operating in the step 3 (S3). Stop time TCn (n = 1... N) measured until stopped in step 6 (S6) is stored in timer storage unit 16 (step 7: S7). Further, the opening monitoring timer 18 is started in accordance with the start of opening operation of the loading gate 6 in step 5 (S5) (step 8: S8). Thereafter, the opening operation of the loading gate 6 is continued until the opening switch 10 is turned off. When the opening switch 10 is turned off (step 9: S9), the opening operation of the loading gate 6 is performed. The operation of the open monitoring timer 18 is stopped (step 11: S11) as well as being stopped (step 10: S10), and the step after the open monitoring timer 18 starts operating in step 8 (S8). 11 (S11), the opening operation time TAn (n = 1... N) measured until it is stopped is stored in the timer storage unit 16 (step 12: S12).

  Thereafter, the opening degree of the loading gate 6 is further increased in consideration of the state of the ready-mixed concrete flowing down from the concrete hopper to the mixer truck through the loading gate 6 and the state of rebound from the receiving hopper of the mixer truck. When the opening operation is performed to increase or the loading gate 6 is closed to decrease the gate opening (step 13: S13), and the loading gate 6 is opened again. The steps 3 (S3) to 12 (S12) are repeated, and the stop time until the loading gate 6 is opened again and the opening time when the loading gate 6 is opened again are set as a timer. The data is stored in the storage unit 16.

  On the other hand, after the step 13 (S13), when the opening degree of the loading gate 6 is decreased, the process proceeds to step 14 (S14), and the stop time of the loading gate 6 is reduced by the start of the stop monitoring timer 20. Start measurement.

  Next, when the operator turns on the closing switch 11 (step 15: S15), the external control device 7 starts the closing operation of the loading gate 6 based on the gate closing operation command from the setting calculation control unit 14. (Step 16: S16). With the start of the closing operation of the loading gate 6, the operation of the stop monitoring timer 20 is stopped (step 17: S17), and the stop monitoring timer 20 starts operating in the step 14 (S14). Stop time TCn (n = 1... N) measured until stopped in step 17 (S17) is stored in timer storage unit 16 (step 18: S18). Further, the closing monitoring timer 19 is started to operate with the start of the closing operation of the loading gate 6 in step 16 (S16) (step 19: S19). Thereafter, the closing operation of the loading gate 6 is continued until the closing switch 11 is turned off. When the closing switch 11 is turned off (step 20: S20), the loading gate 6 is closed. When the stop monitoring timer 19 is stopped (step 21: S21), the operation of the closing monitoring timer 19 is stopped (step 22: S22), and the closing monitoring timer 19 starts operating in step 19 (S19). The closing operation time TBn (n = 1... N) measured until the operation is stopped at 22 (S22) is stored in the timer storage unit 16 (step 23: S23).

  After that, the process returns to step 13 (S13) again so that the operator can load the ready-mixed concrete from the concrete hopper into the mixer truck as quickly as possible without causing overflow from the receiving hopper of the mixer truck. If it is determined that the opening degree of the loading gate 6 needs to be increased in order to carry out, the opening operation of the loading gate 6 is performed according to the procedure from Step 3 (S3) to Step 12 (S12). When the operator determines that the opening degree of the loading gate 6 needs to be decreased, the loading gate 6 is closed by the procedure from Step 14 (S14) to Step 23 (S23). The loading work of the above-mentioned ready-mixed concrete is finished.

  Thereafter, when the operator instructs the completion of teaching by the teaching start / end switch 12 of the control panel 8 (step 24: S24), the timer storage unit 16 sequentially stores the concrete loading work up to that time. The operation patterns of opening, closing, and stopping of the loading gate 6, that is, the operation sequence of the loading gate 6 and the time-series operation data of each operation time are the slump or the first selected in step 1 (S 1). This is stored in the pattern distinction storage unit 15 as a procedure for loading the ready-mixed concrete corresponding to the flow classification.

  After that, when loading concrete concrete hoppers into different mixers from a concrete hopper to different slumps or flow categories, the above-mentioned teaching is repeated, so that the slump and flow categories differ in the pattern distinction storage unit 15. For ready-mixed concrete, the procedure data for loading work should be accumulated.

  Thereafter, when the loading operation of the ready-mixed concrete belonging to the slump or the flow category that has already been taught is performed by the automatic control of the loading gate 6, first, as shown in FIG. The automatic control mode switch 9 is turned on to switch to the automatic control mode (step 26: S26). Thereby, in the setting calculation control part 4, the information input from the batcher plant side at the stage during the mixing of the ready-mixed concrete to be loaded next (step 27: S27) in the mixer of the batcher plant (not shown). From the determination of the slump or flow classification of the ready-mixed concrete being mixed (step 28: S28), among the various slump or flow classifications stored in the pattern distinction storage unit 15, The time-series operation data of each open / close / stop operation pattern of the loading gate 6 taught when the loading of the ready-mixed concrete corresponding to the slump or flow of the ready-mixed concrete is read (step 29: S29) ). It should be noted that the determination of the ready concrete slump or flow classification in the step 28 (S28) and the reading of the time series operation data of the loading gate during the loading of the corresponding ready concrete in the step 29 (S29) The mixing of the ready-mixed concrete by the mixer (step 30: S30) and the discharging of the ready-mixed concrete from the mixer to the concrete hopper (step 31: S31) may be performed in parallel. After that, when loading the ready concrete in the concrete hopper into the mixer truck via the loading gate 6 (step 32: S32), when reading from the pattern distinction storage unit 15 in the step 29 (S29) The loading gate 6 is opened, closed, and stopped according to the sequence operation data, and the loading work of the above-mentioned ready-mixed concrete on the mixer truck is performed.

  Thus, since the loading gate 6 can be automatically controlled in the same operation sequence and operation time as the manual control of the loading gate 6 by a skilled operator, the ready-mixed concrete flows down from the concrete hopper through the loading gate 6 to the mixer truck. Can be prevented from overflowing from the receiving hopper of the mixer truck, and the loading operation can be performed quickly, and the time required for the loading operation can be shortened. Moreover, the automatic control of the loading gate 6 can be performed by anyone because it is only necessary to turn on the automatic control mode switch 9. Moreover, it is not necessary to provide any sensors on the side of the mixer vehicle.

  In the above-mentioned slump / flow selection switch 13, the time-series operation data of each operation of opening, closing and stopping of the loading gate 6 during the loading of the ready-mixed concrete is already stored in the pattern distinction storage unit 15. If the same section is selected and teaching operation as shown in FIG. 2 is performed, each of the opening, closing, and stopping operations of the loading gate 6 for loading the ready-mixed concrete in the section is performed. It becomes possible to update the time series motion data.

  Further, without directing the slump or flow classification of the ready-mixed concrete by the slump / flow selection switch 13 or instructing the start of teaching by operating the teaching start / end switch 12, It is also possible to operate the closing switch 11 to manually operate the loading gate 6 without teaching, and to load the ready-mixed concrete into the mixer truck.

  The present invention is not limited only to the above embodiment, and the number of slumps or flows of ready-mixed concrete that is divided by the slump / flow selection switch 13 and the pattern storage unit 15 is arbitrary. The loading gate 6 is described as being of the type that is opened and closed by the fluid pressure cylinder, but can be applied to the loading gate 6 of any opening and closing type, in which case the loading gate 6 If the external control device 7 can make the loading gate 6 perform the opening, closing, and stopping operations, for example, the rotation of the motor that opens and closes the loading gate 6 is electrically controlled.
