Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Also, not all combinations of features described in the embodiments are essential for the solution of the invention.

FIG. 1 is a schematic diagram showing an example of a vehicle 20 equipped with a ready-mixed concrete manufacturing apparatus 10 according to this embodiment. FIG. 2 is a diagram showing an example of functional blocks showing the overall configuration of the ready-mixed concrete manufacturing apparatus 10 according to this embodiment. The ready-mixed concrete manufacturing apparatus 10 is a mobile ready-mixed concrete manufacturing plant mounted on a loading platform 22 of a vehicle 20 such as a truck. The ready-mixed concrete manufacturing apparatus 10 may be mounted on a moving object other than a vehicle, such as a ship or an aircraft. Ready-mixed concrete manufacturing apparatus 10 may be installed, for example, in the bed of a medium-sized truck.

The ready-mixed concrete manufacturing apparatus 10 includes a control device 100 , a mixer 200 , a main hopper 300 , a belt conveyor 302 , a sub-hopper 310 , a screw feeder 312 , a tank 320 and a pump 322 .

The control device 100 controls the ready-mixed concrete manufacturing device 10 as a whole. The control device 100 may be configured by a computer having a CPU and memory.

The mixer 200 has an accommodation section 202 , a stirring blade section 204 , a driving section 206 and a weighing sensor 208 . The container 202 contains a plurality of materials for producing ready-mixed concrete. Ready-mixed concrete includes ultra-fast-hardening concrete, ultra-fast-hardening mortar, fiber-reinforced concrete, fiber-reinforced mortar, porous concrete, greening concrete, night-time special concrete, night-time special mortar, cross-section repair material, tile paving material, soil paving material, or Sanwa soil. OK.

The storage unit 202 has a bucket-shaped container and a lid that seals the container. The stirring blade portion 204 is installed inside the container of the housing portion 202 . The stirring blade part 204 is arranged in the container and has a stirring blade for stirring a plurality of materials in the container and a base shaft connecting the stirring blades. The drive unit 206 has a motor, and a base shaft that connects the stirring blades to the rotating shaft of the motor is fixed. By driving the motor, the stirring blade rotates around the rotating shaft. The mixer 200 may be a pan-type mixer, and the rotating shaft of the motor may stand vertically from the bottom of the container or hang vertically from the top of the container. Mixer 200 may be a forced twin-axis mixer or a canting mixer. A weighing sensor 208 measures the weight of the contents in the container of the storage section 202 . The weight sensor 208 may be a load cell that outputs an electrical signal corresponding to the weight of the contents.

The two main hoppers 300 each store ready-mixed concrete material. One main hopper 300 stores, for example, fine aggregate such as sand, and the other main hopper 300 stores, for example, coarse aggregate such as gravel. The belt conveyor 302 conveys the material stored in the main hopper 300 to the mixer 200 and throws it into the container of the storage section 202 .

The sub-hopper 310 stores materials for ready-mixed concrete. The sub-hopper 310 stores, for example, cement or mortar premixed with cement and fine aggregate. The capacity of sub-hopper 310 may be smaller than the capacity of main hopper 300 .

Tank 320 stores the liquid ingredients of ready-mixed concrete. Tank 320 stores water, for example. The pump 322 sucks up a liquid such as water in the tank 320 and supplies it into the container of the housing section 202 .

By repeating the production of ready-mixed concrete using the ready-mixed concrete production apparatus 10 configured in this way, the agitating blades of the mixer 200, the base shaft, the inner wall of the housing portion 202, and the like adhere to the ready-mixed concrete and other substances. . A large amount of deposits may adversely affect the mixing of ready-mixed concrete by the mixer 200 . Therefore, it is necessary to wash the inside of the container of the mixer 200 with water or the like at an appropriate timing. In the case of a normal ready-mixed concrete manufacturing apparatus that is not mobile, the batch interval is constant. Just do it.

However, the ready-mixed concrete manufacturing apparatus 10 according to the present embodiment is mounted on a vehicle 20 and moved. The ready-mixed concrete manufacturing apparatus 10 is often used in special sites where large trucks and the like cannot enter. At such a site, when the vehicle 20 moves from place to place for each placement, the time required for the vehicle 20 to move may not be constant. Therefore, batch intervals are not constant. As the batch interval becomes longer, the deposits attached to the inside of the container of the mixer 200 become hard and difficult to remove. If the ready-mixed concrete is repeatedly stirred by the mixer 200 in such a state, the cleaning timing will be delayed, and there is a possibility that the amount of deposits on the stirring blades and the like will increase.

Therefore, according to the ready-mixed concrete manufacturing apparatus 10 according to the present embodiment, the amount of deposits on at least one of the inner walls of the stirring blade portion 204 and the housing portion 202 is predicted, and when the amount of deposits exceeds the threshold value , to notify the outside that the mixer 200 should be cleaned.

The control device 100 includes a weight acquisition section 102 , a torque value acquisition section 104 , a prediction section 106 , a notification section 108 , a derivation section 110 , a correction section 112 and a storage section 114 .

The weight acquisition unit 102 acquires the weight of the content inside the storage unit 202 . The weight acquisition unit 102 acquires the weight of the content inside the storage unit 202 via the weighing sensor 208 . After the mixer 200 has been washed, the weight acquisition unit 102 acquires the reference weight of the contents while the container of the storage unit 202 is empty, and provides it to the prediction unit 106 . An operator may manually clean the mixer 200 . The mixer 200 has a cleaning function and may automatically clean. The cleaning function may be a function of cleaning the inside of the container by spraying a cleaning liquid such as water from a nozzle provided inside the container 202 .

The prediction unit 106 estimates the amount of deposits including a plurality of materials adhering to at least one of the stirring blade unit 204 and the inner wall of the storage unit 202 before charging one batch of multiple materials into the storage unit 202. Predict. Adherence of deposits to the stirring blade portion 204 includes adhesion to at least one of the stirring blades and the base shaft connecting the stirring blades. The prediction unit 106 acquires the current weight of the contents in the container 202 from the weight acquisition unit 102 before one batch of materials is put into the container 202 . The prediction unit 106 may predict the amount of deposit based on the reference weight and the current weight. The prediction unit 106 may predict the amount of adhering matter by subtracting the reference weight from the current weight.

The torque value acquiring unit 104 acquires the torque value when the driving unit 206 rotates the stirring blade unit 204 . The torque value acquisition unit 104 may acquire, as the torque value, a current value input to a motor that rotates the stirring blades, or a value obtained by multiplying the current value by a predetermined coefficient. After washing the mixer 200 , the control device 100 drives the drive section 206 to rotate the stirring blade section 204 while the container of the storage section 202 is empty. The torque value acquisition unit 104 acquires the torque value when the drive unit 206 rotates the stirring blade unit 204 while the container of the storage unit 202 is empty, as a reference torque value, and provides it to the prediction unit 106. .

The prediction unit 106 acquires the current torque value when the drive unit 206 rotates the stirring blade unit 204 from the torque value acquisition unit 104 before putting one batch of a plurality of materials into the storage unit 202. . The prediction unit 106 may predict the amount of deposit based on the reference torque value and the current torque value. The prediction unit 106 may predict the amount of deposits according to predetermined relationship information indicating the relationship between the difference between the reference torque value and the current torque value and the amount of deposits. The predetermined relational information may be derived from an experiment in which torque values are actually obtained while changing the amount of adhering matter, and may be stored in advance in storage unit 114 of control device 100 .

Based on the weight acquired by the weight acquisition unit 102 and the torque value acquired by the torque value acquisition unit 104, the prediction unit 106, before putting one batch of a plurality of materials into the storage unit 202, The amount of deposits may be predicted. Predicting unit 106 determines the amount of attached matter predicted from the weight obtained by weight obtaining unit 102 and the amount of attached matter predicted from the torque value obtained by torque value obtaining unit 104. You can predict the amount of Prediction unit 106 predicts the amount of deposits predicted from the weight acquired by weight acquisition unit 102 and the amount of deposits estimated from the torque value acquired by torque value acquisition unit 104, respectively. After weighting, the amount of deposit may be predicted from the weighted amount of each deposit.

When the amount of deposit predicted by the prediction unit 106 exceeds the threshold, the notification unit 108 instructs that the inside of the storage unit 202 should be cleaned before one batch of a plurality of materials is put into the storage unit 202. to notify you. The notification unit 108 may notify by causing the display unit of the control device 100 to display a message indicating that the inside of the housing unit 202 should be cleaned. The notification unit 108 may notify the administrator of the ready-mixed concrete manufacturing apparatus 10 by sending an e-mail or the like with a message indicating that the inside of the storage unit 202 should be washed. The notification unit 108 may notify by turning on a lamp provided in the ready-mixed concrete manufacturing apparatus 10 to indicate that cleaning should be performed. The notification unit 108 may notify by outputting a voice indicating that cleaning is to be performed from a microphone provided in the ready-mixed concrete manufacturing apparatus 10 . The notification unit 108 may notify the control unit of the cleaning function provided in the mixer 200 by instructing the cleaning. The cleaning function controller may receive instructions to perform cleaning of the mixer 200 .

The derivation unit 110 calculates the torque value based on the slump relation information indicating the relationship between the torque value when the driving unit 206 rotates the stirring blade unit 204 and the slump value of the ready-mixed concrete being stirred by the stirring blade unit 204. A slump value of ready-mixed concrete manufactured from a plurality of materials corresponding to the torque value acquired by the acquisition unit 104 is derived. The slump-related information may be a function indicating the relationship between the torque value and the slump value. The slump-related information may be, for example, a function representing a curve L1 representing the relationship between the torque value and the slump value as shown in FIG. The slump-related information may be derived in advance from the relationship between the torque value and the slump value by actually measuring the slump value using a slump cone while changing the torque value. The slump-related information may be stored in the storage unit 114 in advance.

Here, when deposits are attached to at least one of the inner wall of the stirring blade portion 204 and the housing portion 202, there is a possibility that the slump relationship between the torque value and the slump value will change. That is, when the derivation unit 110 derives the slump value from the torque value based on the slump-related information derived in a state in which no adhering matter is present, the error in the slump value may increase depending on the amount of adhering matter. have a nature. If the amount of deposits increases, the slump value may become larger than it actually is.

Therefore, the correction unit 112 corrects the slump value based on the amount of adhered matter predicted by the prediction unit 106 . The correction unit 112 may correct the slump value by correcting the slump-related information based on the amount of adhering matter predicted by the prediction unit 106 . The correction unit 112 may correct the slump-related information based on the correction-related information indicating the relationship between the amount of adhering matter and the amount of correction. For example, as shown in FIG. 3, the correction unit 112 adjusts the curve L1 from the curve L1 so that the slump value derived from the torque value is reduced by the amount of correction corresponding to the amount of deposit predicted by the prediction unit 106. The slump-related information may be corrected in L2.

FIG. 4 is a flow chart showing an example of a procedure for notifying a cleaning alert according to the amount of deposits.

Before charging a batch of a plurality of materials into the storage section 202, the prediction section 106 estimates the amount of deposits including a plurality of materials attached to at least one of the stirring blade section 204 and the inner wall of the storage section 202. , based on at least one of the weight and torque value of the contents in the container 202 (S100). The correction unit 112 corrects the slump-related information for deriving the slump value based on the amount of deposit based on the amount of deposit (S102).

The notification unit 108 determines whether or not the predicted amount of attached matter exceeds the threshold (S104). If the predicted amount of adhered matter exceeds the threshold, the notification unit 108 issues a cleaning alert indicating that the mixer 200 should be cleaned before a batch of materials is put into the container 202. Notify (S106). If the predicted deposit amount does not exceed the threshold, the controller 100 controls the belt conveyor 302, the screw feeder 312, and the pump 322 to load a batch of materials into the container 202. (S108).

As described above, according to the present embodiment, it is determined whether or not the mixer 200 should be cleaned each time one batch of materials is put into the container 202 . As a result, it is possible to prevent repeated production of ready-mixed concrete in a state in which many deposits are attached to the stirring blade, the base shaft, or the inner wall of the housing portion 202 . Therefore, when many deposits are attached to the stirring blade, the base shaft, or the inner wall of the container 202, the mixing of the ready-mixed concrete by the mixer 200 becomes insufficient, and the amount of air contained in the ready-mixed concrete becomes less than the desired amount. It is possible to prevent in advance that ready-mixed concrete of desired quality cannot be produced due to the amount not being reached. In addition, it is possible to prevent the material from overflowing from the container of the storage section 202 due to a large amount of deposits adhering to the stirring blade, the base shaft, or the inner wall of the storage section 202 .
