Summary of the Invention

Problems to be Solved by the Invention

[0004] The addition and supply of civil engineering additives are usually carried out outdoors. In addition, the viscosity of civil engineering additives becomes lower in summer when the temperature is high, while it becomes higher in winter when the temperature is low.

[Brief explanation of the drawing]

[0011] [Figure 1] This diagram shows the configuration of the civil engineering additive supply device according to Embodiment 1. [Figure 2] This is a flowchart showing the information processing by the controller in Embodiment 1. [Figure 3] This diagram shows the configuration of the civil engineering additive supply device according to Embodiment 2. [Figure 4]This is a flowchart showing the information processing by the controller in Embodiment 2. [Modes for carrying out the invention]

[0012] The embodiments will be described in detail below.

[0013] (Embodiment 1) Figure 1 shows a civil engineering additive supply device 10 according to Embodiment 1. This civil engineering additive supply device 10 is mainly used to add and supply civil engineering additives A, such as dispersants, when preparing cement milk outdoors.

[0014] The civil engineering additive supply device 10 according to Embodiment 1 comprises an IBC container 11 for storing civil engineering additive A and an additive supply pipe 12 for supplying the civil engineering additive A. One end of the additive supply pipe 12 is connected to the IBC container 11, and it extends from the IBC container 11 to above the upper opening of the mixer 22, which is the destination for the additive supply and is located above the agitator 21, and a check valve 13 is provided at the tip of the other end. Therefore, in this civil engineering additive supply device 10, the civil engineering additive A is discharged into the gas phase from the additive supply pipe 12 and supplied to the mixer 22, and the check valve 13 regulates the supply of too little or too much civil engineering additive A. The civil engineering additive supply device 10 may also be configured to supply the civil engineering additive A from the additive supply pipe 12 to the agitator 21.

[0015] The civil engineering additive supply device 10 according to Embodiment 1 includes a pump 14 interposed in the additive supply pipe 12. The pump 14 delivers the civil engineering additive A from the IBC container 11 via the additive supply pipe 12. Therefore, this pump 14 constitutes the liquid delivery unit.

[0016] The civil engineering additive supply device 10 according to Embodiment 1 includes a temperature sensor 15 provided in a portion of the additive supply pipe 12 upstream of the pump 14. The temperature sensor 15 detects the temperature information of the civil engineering additive A as viscosity-related information of the civil engineering additive A in the additive supply pipe 12. Therefore, this temperature sensor 15 constitutes a viscosity-related information detection unit.

[0017] The civil engineering additive supply device 10 according to Embodiment 1 includes a filter 16 interposed in a portion of the additive supply pipe 12 further upstream of the temperature sensor 15. The filter 16 removes foreign substances mixed in the civil engineering additive A to prevent damage to the pump 14.

[0018] The civil engineering additive supply device 10 according to Embodiment 1 includes a controller 17 to which the pump 14 and the temperature sensor 15 are connected. The controller 17 controls the liquid feeding of the civil engineering additive A by the pump 14. Therefore, this controller 17 constitutes a liquid feeding control unit.

[0019] The controller 17 is composed of a computer in which a computer program for additive liquid feeding control is installed.

[0020] The computer program for additive liquid feeding control generally causes the computer constituting the controller 17 to prompt the input of the set amount X of the civil engineering additive A to be supplied, acquire the temperature information of the civil engineering additive A from the temperature sensor 15, calculate the liquid feeding time T of the civil engineering additive A by the pump 14 required to feed the set amount X of the civil engineering additive A with a viscosity corresponding to the acquired temperature information, start the liquid feeding of the civil engineering additive A to the pump 14, when the calculated liquid feeding time T has elapsed since the start of the liquid feeding of the civil engineering additive A, stop the liquid feeding of the civil engineering additive A by the pump 14, and execute. This computer program can be an independent transaction object as a computer-readable recording medium such as a CD-ROM.

[0021] Next, a civil engineering additive supply method using the civil engineering additive supply device 10 according to Embodiment 1 will be specifically described according to the flowchart of FIG. 2.

[0022] First, in step S1 after starting, a display (not shown) such as a display of the controller 17 prompts an input of the set amount X of the civil engineering additive A to be supplied. When appropriate input is received from an input unit (not shown) such as a keyboard of the controller 17, the process proceeds to the subsequent step S2. Therefore, the controller 17 that executes this step S1 constitutes a supply amount input request means.

[0023] In step S2, temperature information of the civil engineering additive A is acquired from the temperature sensor 15, and the process proceeds to the subsequent step S3. Therefore, the controller 17 that executes this step S2 constitutes a viscosity-related information acquisition means.

[0024] In step S3, the liquid feeding time T required to feed the set amount X of the civil engineering additive A having a viscosity corresponding to the acquired temperature information by the pump 14 is calculated, and the process proceeds to the subsequent step S4. Therefore, the controller 17 that executes this step S3 constitutes a liquid feeding time calculation means. Here, the calculation of this liquid feeding time T is performed based on the relationship data between the temperature and viscosity of the civil engineering additive A and the relationship data between the viscosity of the civil engineering additive A and the liquid feeding amount by the pump 14.

[0025] In step S4, the power supply to the pump 14 is turned on, and the pump 14 is caused to start feeding the civil engineering additive A stored in the IBC container 11 through the additive supply pipe 12, and the process proceeds to the subsequent step S5. Therefore, the controller 17 that executes this step S4 constitutes a liquid feeding start means.

[0026] In step S5, it is determined whether the elapsed time t since the start of pumping the civil engineering additive A is equal to or greater than the calculated pumping time T. If YES, the process proceeds to step S6, where the power supply to pump 14 is turned off, stopping the pumping of civil engineering additive A by pump 14 and ending the process. If NO, the process returns to step S5.

[0027] According to the civil engineering additive supply device 10 of Embodiment 1 with the above configuration, temperature information, which is viscosity-related information of the civil engineering additive A, is acquired, and the liquid delivery time T required to deliver a set amount X of civil engineering additive A with viscosity corresponding to that temperature information is calculated. Since the viscosity of the civil engineering additive A is reflected in the liquid delivery time T, the set amount X of civil engineering additive A can be supplied regardless of the ambient temperature.

[0028] (Embodiment 2) Figure 3 shows a civil engineering additive supply device 10 according to Embodiment 2. Parts with the same configuration as those in Embodiment 1 are denoted by the same reference numerals.

[0029] The civil engineering additive supply device 10 according to Embodiment 2 includes, in addition to the configuration of the civil engineering additive supply device 10 according to Embodiment 1, a flow meter 18 provided in the portion of the additive supply pipe 12 downstream of the pump 14. The flow meter 18 detects the flow rate information of the civil engineering additive A supplied by the pump 14. Therefore, this flow meter 18 constitutes the flow rate information detection unit. The flow meter 18 is connected to the controller 17. It is preferable that this flow meter 18 is a Coriolis type.

[0030] In the civil engineering additive supply device 10 according to Embodiment 2, the controller 17 is composed of a computer on which a computer program for controlling the supply of additives is installed.

[0031] The computer program for controlling the delivery of the additive is, broadly speaking, used in the computer that makes up the controller 17. A procedure to prompt input of the set amount X of the civil engineering additive A to be supplied, Procedure for obtaining temperature information of civil engineering additive A from temperature sensor 15, A procedure for calculating the pumping time T of civil engineering additive A by pump 14 required to deliver a set amount X of civil engineering additive A with viscosity corresponding to the acquired temperature information, and The procedure for starting the supply of civil engineering additive A to pump 14, Procedure for obtaining flow rate information of civil engineering additive A from flow meter 18, A procedure for calculating the total flow rate Y of civil engineering additive A after the start of liquid delivery, using the acquired flow rate information, The procedure for stopping the pump 14 from supplying civil engineering additive A when the calculated total flow rate Y of civil engineering additive A reaches the set amount X of civil engineering additive A before the calculated supply time T has elapsed since the start of supplying civil engineering additive A, and When the calculated pumping time T has elapsed since the start of pumping of civil engineering additive A, the pumping of civil engineering additive A by pump 14 is stopped as a general rule. However, if the calculated total flow rate Y of civil engineering additive A has not reached the set amount X of civil engineering additive A, the pumping of civil engineering additive A by pump 14 is stopped, and pumping of civil engineering additive A by pump 14 is continued. Subsequently, when the calculated total flow rate Y of civil engineering additive A reaches the set amount X of civil engineering additive A, the pumping of civil engineering additive A by pump 14 is stopped. This will cause the computer program to execute. This computer program can be traded independently as a computer-readable recording medium such as a CD-ROM.

[0032] Next, a method for supplying civil engineering additives using the civil engineering additive supply device 10 according to Embodiment 2 will be specifically explained in accordance with the flowchart in Figure 4.

[0033] First, in step SS1 after the start, the display unit (not shown) of the controller 17 prompts the user to input the set amount X of the civil engineering additive A to be supplied. If an appropriate input is received from the input unit (not shown) of the controller 17, such as a keyboard, the system proceeds to the next step SS2.

[0034] In step SS2, temperature information for the civil engineering additive A is obtained from the temperature sensor 15, and the process proceeds to the following step SS3.

[0035] In step SS3, the pumping time T required to deliver the set amount X of civil engineering additive A with viscosity corresponding to the acquired temperature information by the pump 14 is calculated, and the process proceeds to the following step SS4.

[0036] In step SS4, the power supply to the pump 14 is turned on, and the pump 14 is instructed to start pumping the civil engineering additive A stored in the IBC container 11 through the additive supply pipe 12, and the process proceeds to the following step SS5.

[0037] Steps SS1 through SS4 up to this point are the same as steps S1 through S4 of Embodiment 1.

[0038] In step SS5, following step SS4, flow rate information of civil engineering additive A is obtained from the flow meter 18, and the process proceeds to the following step SS6. Therefore, the controller 17 that performs this step SS5 constitutes the flow rate information acquisition means.

[0039] In step SS6, the acquired flow rate information is used to calculate the total flow rate Y by integrating the flow rates of the civil engineering additive A since the start of liquid delivery, and the process proceeds to the following step SS7. Therefore, the controller 17 that executes step SS6 constitutes the total flow rate calculation means.

[0040] In step SS7, it is determined whether the elapsed time t since the start of supplying the civil engineering additive A is less than the calculated supplying time T. If the answer is YES, proceed to step SS8; otherwise, proceed to step SS10.

[0041] In step SS8, it is determined whether the calculated total flow rate Y of civil engineering additive A is equal to or greater than the set amount X of civil engineering additive A. If YES, the process proceeds to step SS9, where the power supply to pump 14 is turned off, stopping the pumping of civil engineering additive A by pump 14 and ending the process. If NO, the process returns to step SS5. Therefore, the controller 17 that executes steps SS7, SS8, and SS9 constitutes the liquid delivery time reduction adjustment means.

[0042] In step SS10, it is determined whether the calculated total flow rate Y of civil engineering additive A is equal to or greater than the set amount X of civil engineering additive A. If YES, the process proceeds to step SS11, where the power supply to pump 14 is turned off, stopping the pumping of civil engineering additive A by pump 14 and ending the process. If NO, the process returns to step SS5. Therefore, after executing steps SS7 and SS10, the controller 17 that executes step SS11 without returning to step SS5 constitutes the liquid supply stop means. Alternatively, the controller 17 that returns from step SS8 to step SS5, executes steps SS7 and SS8 multiple times, and then executes step SS11 constitutes the liquid supply time extension adjustment means.

[0043] According to the civil engineering additive supply device 10 of Embodiment 2 with the above configuration, similar to Embodiment 1, temperature information, which is viscosity-related information of the civil engineering additive A, is acquired, and the liquid delivery time T required to deliver a set amount X of civil engineering additive A with viscosity corresponding to that temperature information is calculated. Since the viscosity of the civil engineering additive A is reflected in the liquid delivery time T, the set amount X of civil engineering additive A can be supplied regardless of the temperature. Moreover, in addition, the total flow rate Y of civil engineering additive A calculated using the flow rate information acquired by the flow meter 18 is also monitored, so the supply of the set amount X of civil engineering additive A can be performed with high accuracy.

[0044] (Other embodiments) In embodiments 1 and 2 described above, the civil engineering additive A is stored in the IBC container 11, but the configuration is not limited to this. For example, depending on the scale of the construction site, the civil engineering additive A may be stored in a bucket as a container.

[0045] In embodiments 1 and 2 described above, temperature information is detected as viscosity-related information for civil engineering additive A. However, the system is not limited to this, and a configuration that directly detects the viscosity information of civil engineering additive A is also possible.

[0046] In embodiments 1 and 2 described above, the configuration was used to detect the temperature information of the civil engineering additive A in the additive supply pipe 12, but the system is not limited to this, and the configuration may also be used to detect the temperature information of the civil engineering additive A in the IBC container 11.
