BRIEF DESCRIPTION OF DRAWINGS
[0011]
Fig. 1A is a plan view of a mixer vehicle according to an embodiment of the present invention.
Fig. IB is a side view of the mixer vehicle.
Fig. 2 is a block diagram illustrating constitution of the mixer vehicle. DESCRIPTION OF EMBODIMENTS
[0012] An embodiment of the present invention will be described below by referring to the attached drawings.
[0013] By referring to Figs. 1A and IB, an entire constitution of a mixer vehicle 100 will be described. The mixer vehicle 100 is a vehicle including an operator’s cabin 11 and a frame 1. The mixer vehicle 100 includes a mixer drum 2 mounted on the frame 1 and capable of loading ready-mixed concrete, a driving device 4 that drives and rotates the mixer drum 2, and a drum driving controller 10 that controls rotation of the mixer drum 2. The mixer vehicle 100 loads the ready-mixed concrete in the mixer drum 2 and transports it. In Fig. IB, the driving device 4 and the like are not shown.
[0014] The mixer drum 2 is a cylindrical container having a bottom rotatably mounted on the frame 1 and has an opening portion 2A on the rear end thereof. The mixer drum 2 is mounted with inclination so that its rotating axis O becomes gradually higher from a front part to a rear part of the vehicle.
[0015] On an upper rear part of the opening portion 2A of the mixer drum 2, a hopper 16 is provided. The ready-mixed concrete that is loaded from a kneading place such as a ready-mixed concrete manufacturing plant or the like is led to the opening portion 2A by the hopper 16. On a lower rear part of the opening portion 2A of the mixer drum 2, a flow guide 17 and a chute 18 are GS11582/PCT -1868 - 4 - provided. The ready-mixed concrete that is discharged from the opening portion 2A is led by the flow guide 17 and the chute 18.
[0016] The mixer drum 2 is driven and rotated at different speeds in a forward direction and in a backward direction by the driving device 4. The driving device 4 uses an engine 3 for running mounted on the mixer vehicle 100 as a power source and drives and rotates the mixer drum 2 by a fluid pressure of a working fluid.
[0017] In the kneading place such as the ready-mixed concrete manufacturing plant and the like, the ready-mixed concrete is made by kneading concrete raw materials such as cement, aggregate, water and the like by a mixer machine. The mixer vehicle 100 transports the ready-mixed concrete loaded into the mixer drum 2 at the kneading place to a casting place. During running of the mixer vehicle 100, the driving device 4 agitates the ready-mixed concrete by rotating/driving the mixer drum 2 in the forward direction in order to keep a quality of the ready-mixed concrete. When the mixer vehicle 100 arrives at the casting place, the driving device 4 drives and rotates the mixer drum 2 in the backward direction. As a result, the ready-mixed concrete is discharged from the mixer drum 2 and cast.
[0018] While the ready-mixed concrete is being transported by the mixer vehicle 100, when an outside air temperature is high and a solar radiation amount is large as in the summer, a surface temperature of the mixer drum 2 rises, and heat transfer from the mixer drum 2 gradually raises the temperature of the ready-mixed concrete in the mixer drum 2 in some cases. When the temperature of the ready-mixed concrete changes largely, the nature of the ready-mixed concrete changes.
[0019] As a measure against the above, the mixer vehicle 100 is provided with a temperature management device 20 that manages driving time A during which the mixer drum 2 is driven with the ready-mixed concrete loaded and a GS11582/PCT-1868 - 5 - temperature C of the ready-mixed concrete loaded in the mixer drum 2.
[0020] As illustrated in Fig. 2, the temperature management device 20 includes a communication device 31 that transmits/receives information relating to the loaded ready-mixed concrete, an outside air temperature detector 35 that detects an outside air temperature, a solar radiation amount detection part 36 that detects a solar radiation amount, a temperature management controller 21 that estimates the temperature C of the ready-mixed concrete on the basis of the aforementioned information and a detection signal, and a display part 37 that displays the temperature C of the ready-mixed concrete in accordance with driving time A of the mixer drum 2 and time.
[0021] When the ready-mixed concrete is loaded into the mixer drum 2 at the kneading place, the following information relating to the ready-mixed concrete is transmitted from a management device (not shown) provided at the kneading place to the temperature management controller 21 through the communication device 31: - Loading time A1 when the load of the ready-mixed concrete into the mixer drum 2 is finished at the kneading place; - A loaded amount F of the ready-mixed concrete loaded into the mixer drum 2 at the kneading place; and - An initial temperature G of the ready-mixed concrete loaded into the mixer drum 2 at the kneading place.
[0022] The temperature management controller 21 includes an loading time input part 22 into which the loading time A1 is input, a loaded amount input part 23 into which a loaded amount F is input, and an initial temperature input part 24 into which the initial temperature G is input on the basis of a signal received by the communication device 31.
[0023] The temperature management controller 21 includes a driving time GS11582/PCT-1868 - 6 - measurement part 25 that measures driving time A during which the mixer drum 2 is driven with the ready-mixed concrete loaded. The driving time measurement part 25 starts measurement of the driving time A on the basis of the loading time A1 sent from the loading time input part 22. The driving time measurement part 25, on the basis of a signal sent from the drum driving controller 10, sets discharge end time A2 to measurement end time. The discharge end time A2 is a time that the mixer drum 2 is driven and rotated in the backward direction and discharge of the ready-mixed concrete is finished. The measurement end time is a time that the measurement of the driving time A is finished. That is, the driving time measurement part 25 starts the measurement of the driving time A with end of the load of the ready-mixed concrete into the mixer drum 2 and finishes the measurement of the driving time A with end of discharge of the ready-mixed concrete form the mixer drum 2.
[0024] The driving time measurement part 25 may be so constituted to start measurement of the driving time A by a switch operation of an operator and finishes the measurement of the driving time A by the switch operation of the operator, not limited to the aforementioned constitution.
[0025] The outside air temperature detector 35 is mounted on the mixer vehicle 100. The outside air temperature detector 35 converts a change of electric resistance by a thermocouple to an electric signal and measures an outside air temperature D (°C).
[0026] The solar radiation amount detection part 36 is mounted on the mixer vehicle 100. The solar radiation amount detection part 36 converts the solar radiation amount to an electric signal by using a photoelectric element or a thermocouple, for example, and measures a radiation energy amount received by the photoelectric element or the thermocouple per part area for part time from the sun as a solar radiation amount E (kW/m2). GS11582/PCT-1868 - 7 - [0027] The drum surface temperature estimation part 26 acquires a surface temperature B of the mixer drum 2 on the basis of a map using the outside air temperature D and the solar radiation amount E as parameters. The drum surface temperature estimation part 26 stores the map (not shown) setting a relation among the outside air temperature D, the solar radiation amount E, and the surface temperature B of the mixer drum 2. This relation is obtained by an experiment or simulation. The surface temperature B of the mixer drum 2, which rises in accordance with the outside air temperature D and the solar radiation amount E, is accurately estimated on the basis of this map.
[0028] The drum surface temperature estimation part 26 may be so constituted that the surface temperature B of the mixer drum 2 is acquired on the basis of the map using the detected outside air temperature D as a parameter, and the acquired surface temperature B is corrected on the basis of the solar radiation amount E, not limited to the aforementioned constitution.
[0029] The drum surface temperature estimation part 26 may also be so constituted that the surface temperature B of the mixer drum 2 is acquired on the basis of the map using the calculated solar radiation amount E as a parameter, and the acquired surface temperature B is corrected on the basis of the outside air temperature D.
[0030] The ready-mixed concrete temperature estimation part 27 estimates the temperature C of the ready-mixed concrete loaded in the mixer drum 2 on the basis of the loaded amount F of the ready-mixed concrete loaded into the mixer drum 2, the initial temperature G of the ready-mixed concrete loaded into the mixer drum 2, the measured driving time A of the mixer drum 2, and the estimated surface temperature B of the mixer drum 2.
[0031] The ready-mixed concrete that is loaded in the mixer drum 2 has its temperature raised by reaction heat generated by a chemical reaction, and the GS11582/PCT -1868 - 8 - temperature of the ready-mixed concrete rises/falls by the heat received from the mixer drum 2. The ready-mixed concrete temperature estimation part 27 estimates the temperature C of the ready-mixed concrete on the basis of the reaction heat amount generated in accordance with the driving time A of the mixer drum 2 and a heat amount received in accordance with the surface temperature B of the mixer drum 2. Specifically, the ready-mixed concrete temperature estimation part 27 estimates the temperature C of the ready-mixed concrete in correspondence with the fact that the higher the initial temperature G of the ready-mixed concrete is, the smaller a degree of temperature rise of the ready-mixed concrete by the heat received from the mixer drum 2 becomes. Moreover, the ready-mixed concrete temperature estimation part 27 estimates the temperature C of the ready-mixed concrete in correspondence with a fact that the larger the loaded amount F of the ready-mixed concrete increases, the smaller the degree of temperature rise of the ready-mixed concrete by the heat received from the mixer drum 2 becomes.
[0032] The display part 37, which is provided in the operator’s cabin 11, displays a graph indicating a change of the temperature C of the ready-mixed concrete according to the driving time A of the mixer drum 2 or the like. As a result, the operator can manage time until the loaded ready-mixed concrete is discharged and cast or the like by looking at the graph indicating the change of the temperature C of the ready-mixed concrete according to the driving time A of the mixer drum 2 and the like.
[0033] The temperature management device 20 may transmit the information relating to the ready-mixed concrete to the server computer (not shown) via the communication device 31 and an information line network such as the Internet or the like. As a result, the change of the temperature C of the ready-mixed concrete according to the driving time A of the mixer drum 2 can be recorded in the server computer. GS11582/PCT-1868 - 9 - [0034] According to the aforementioned embodiment, the following working effects are exerted.
[0035] The temperature management controller 21 of the mixer vehicle 100 includes the driving time measurement part 25 that measures the driving time A during which the mixer drum 2 is driven with the ready-mixed concrete loaded, the drum surface temperature estimation part 26 that estimates the surface temperature B of the mixer drum 2, and the ready-mixed concrete temperature estimation part 27 that estimates the temperature C of the ready-mixed concrete loaded in the mixer drum 2 on the basis of the measured driving time A of the mixer drum 2 and the estimated surface temperature B of the mixer drum 2.
[0036] The temperature estimating method of the ready-mixed concrete includes measuring the driving time A during which the mixer drum 2 is driven with the ready-mixed concrete loaded, estimating of the surface temperature B of the mixer drum 2, and estimating of the temperature C of the ready-mixed concrete loaded in the mixer drum 2 on the basis of the measured driving time A of the mixer drum 2 and the estimated surface temperature B of the mixer drum 2.
[0037] On the basis of the aforementioned constitution, the temperature C of the ready-mixed concrete loaded in the mixer drum 2 is estimated on the basis of a measured value A of the driving time of the mixer drum 2 and an estimated value B of the surface temperature of the mixer drum 2 and thus, the temperature of the ready-mixed concrete can be acquired without using the contact-type temperature sensor inserted into the ready-mixed concrete or the non-contact type temperature sensor installed so as to be faced with the inside of the mixer drum 2. Therefore, the temperature of the ready-mixed concrete can be managed with a simple method.
[0038] The temperature management device 20 of the mixer vehicle 100 GS11582/PCT-1868 - 10 - includes the outside air temperature detector 35 that detects the outside air temperature D. The drum surface temperature estimation part 26 that estimates the surface temperature B of the mixer drum 2 on the basis of the detected outside air temperature D.
[0039] On the basis of the aforementioned constitution, the surface temperature B of the mixer drum 2, which rises in accordance with the outside air temperature D, is accurately estimated.
[0040] The temperature management device 20 of the mixer vehicle 100 includes the solar radiation amount detection part 36 that detects the solar radiation amount E. The drum surface temperature estimation part 26 estimates the surface temperature B of the mixer drum 2 on the basis of the calculated solar radiation amount E.
[0041] On the basis of the aforementioned constitution, the surface temperature B of the mixer drum 2, which rises in accordance with the solar radiation amount E, can be accurately estimated.
[0042] The temperature management device 20 of the mixer vehicle 100 includes the loaded amount input part 23 that inputs the loaded amount F of the ready-mixed concrete loaded in the mixer drum 2. The ready-mixed concrete temperature estimation part 27 estimates the temperature C of the ready-mixed concrete in the mixer drum 2 on the basis of the loaded amount F of the ready-mixed concrete loaded in the mixer drum 2.
[0043] On the basis of the aforementioned constitution, in correspondence with the fact that the larger the loaded amount F of the ready-mixed concrete loaded in the mixer drum 2 increases, the smaller the degree of temperature rise of the ready-mixed concrete by the heat received from the mixer drum 2 becomes, the temperature C of the ready-mixed concrete in the mixer drum 2 is accurately estimated.
[0044] When the loaded amount F of the ready-mixed concrete loaded into GS11582/PCT-1868 - 11 - the mixer drum 2 at the kneading place is managed substantially constant, the ready-mixed concrete temperature estimation part 27 may be so constituted that the temperature C of the ready-mixed concrete is estimated with the loaded amount F of the ready-mixed concrete as a constant value without providing the loaded amount input part 23 in the mixer vehicle 100 (temperature management device 20).
[0045] The temperature management device 20 of the mixer vehicle 100 includes the initial temperature input part 24 that inputs the initial temperature G of the ready-mixed concrete loaded in the mixer drum 2. The ready-mixed concrete temperature estimation part 27 estimates the temperature C of the ready-mixed concrete in the mixer drum 2 on the basis of the initial temperature G of the input ready-mixed concrete.
[0046] On the basis of the aforementioned constitution, in correspondence with the fact that the higher the initial temperature G of the ready-mixed concrete loaded into the mixer drum 2 is, the higher the temperature of the ready-mixed concrete transported by the mixer vehicle 100 becomes, the temperature C of the ready-mixed concrete in the mixer drum 2 is accurately estimated.
[0047] When the initial temperature G of the ready-mixed concrete loaded into the mixer drum 2 at the kneading place is managed substantially constant, the ready-mixed concrete temperature estimation part 27 may be so constituted that the temperature C of the ready-mixed concrete is estimated with the initial temperature G of the ready-mixed concrete as a constant value without providing the initial temperature input part 24 in the mixer vehicle 100 (temperature management device 20).
[0048] Embodiments of this invention were described above, but the above embodiments are merely examples of applications of this invention, and the technical scope of this invention is not limited to the specific constitutions of GS11582/PCT-1868 - 12 - the above embodiments.
[0049] In the aforementioned embodiment, the drum surface temperature estimation part 26 is constituted to estimate the surface temperature B of the mixer drum 2 on the basis of the detected outside air temperature D and the calculated solar radiation amount E but it may be so constituted that the surface temperature B of the mixer drum 2 is estimated on the basis of either one of the detected outside air temperature D or the calculated solar radiation amount E.
