<p>An auto-controlled feeding apparatus of mineral based accelerating agent and a method for feeding thereof, for sensing a movement of a piston by which concrete is discharged and fluid pressure by the movement of the piston, and controlling an injection amount of an accelerating agent, so that the accelerating agent is uniformly mixed into the concrete. The auto-controlled feeding apparatus of the accelerating agent according to an embodiment of the present invention comprises: a first sensor for sensing a movement of a first piston according to a reciprocating process of the first piston; a second sensor for sensing a movement of a second piston according to a reciprocating of the second piston; an accelerating agent control member for controlling an accelerating agent amount sprayed to an accelerating agent supply device; and a controller for controlling the accelerating agent control member, wherein the first piston stops between an intake process and a compression process during a first time, and the second piston stops between the intake process and the compression process during a second time, wherein if the first sensor senses the stopping of the first sensor, the first sensor transmits a first electronic signal to the controller during the first time, and if the second sensor senses the stopping of the second sensor, the second sensor transmits a second electronic signal to the controller during the second time, and wherein if the controller receives at least one stop signal among the first electronic signal and the second electronic signal, the controller is able to control the accelerating agent control member not to be sprayed corresponding to the stop signal.</p> |
