Abstract

PURPOSE: To control a robot so that the pouring of molten metal into the inner part of a mold is suitably executed by connecting a force sensor, camera and completing sensor with a robot controller through a fuzzy unit. CONSTITUTION: The robot 1 tilts a ladle 2 according to the pre-inputted program and the molten metal 11 in the ladle 2 is poured into the mold 3. On the other hand, the molten metal wt. in the ladle 2 is sequentially detected with the force sensor 5, and the width, direction and speed of the molten metal at the time of pouring, are sequentially observed with the camera 5, and when a feeder head 3a level is risen, this condition is detected with a range finder sensor 6. Then, these information is transmitted to the fuzzy unit 8 through an I/T panel 7 and the movement command is transmitted to the robot controller 9 from the fuzzy unit 8 so that the pouring speed becomes the constant. The pouring quantity per unit time is controlled to the fixed value or the arbitrary value based on the detection, and the robot 1 pours the molten metal 11 into the inner part of the mold 3.

As a method of using the pouring device, there are a teaching playback method and a method of feeding back the rising height information in addition to the teaching playback method. The teaching playback method is that the work content is programmed into the robot in advance, and the robot can increase the tilt angle of the ladle containing the molten metal in sequence according to the program so that pouring can be performed at a constant pouring speed. It is the one. In addition to this, the method of providing feedback is such that a sensor detects the feeder port and the robot stops the pouring when the information of the specified height is obtained.

However, in the case of the teaching playback system, the tilt angle of the ladle and the pouring amount are not proportional, and if slag or the like adheres to the pouring port of the ladle, the pouring width and pouring direction. Since the pouring speed and the pouring speed change, the pouring speed is not constant, and when pouring the sand into the sand mold, sand may be entrained and the quality may not be constant. Also in the case of the feedback method, sand may be caught when pouring into the sand mold.

The structure of the pouring device according to the present invention is shown in FIG. In the figure, 1 is a robot, 2 is a ladle for containing molten metal, and 3 is a mold. A force sensor 4 for measuring the weight of the ladle 2 containing the molten metal is provided between the hand 1 a of the robot 1 and the ladle 2. That is, the robot 1 pours the molten metal into the mold 3 while tilting the ladle 2 held by the hand 1a via the force sensor 4, and at the same time,
The weight of the remaining molten metal will be measured. A camera 5 is provided to monitor the state of the pouring spout of the ladle 2. This is because when the slag or the like adheres to the pouring port due to pouring, the pouring width, pouring direction, and pouring speed change, and this is monitored and adjusted. Further, a distance sensor 6 as an end sensor is provided above the feeder 3a in order to detect the rising of the bath and stop the pouring. This is to detect the rise of the feeder 3a by measuring the distance, and a temperature sensor or a conductivity sensor may be used instead of the distance sensor.

Next, the operation of the pouring device will be described.
The robot 1 tilts the ladle 2 according to a program input in advance, and pours the molten metal 11 in the ladle 2 into the mold 3. On the other hand, when the weight of the molten metal in the ladle 2 is sequentially detected by the force sensor 4, the width, direction, and speed of the molten metal when being poured by the camera 5 are sequentially monitored, and when the distance sensor 6 raises the feeder 3a. This is detected. Then, these pieces of information are sent to the fuzzy unit 8 via the I / F board 7, and an operation command is sent from the fuzzy unit 8 to the robot controller 9 so that the pouring speed becomes constant.

Based on the above-mentioned detection, the robot 1 pours the molten metal 11 into the mold 3 while controlling the amount of molten metal per unit time to be constant or arbitrarily. For example, the amount of pouring should be reduced at first and gradually increased, or the tilt of the ladle should be increased so that the prescribed pouring amount can be secured even if the slag, etc., narrows the pouring port of the ladle. If the sprue becomes wider, reduce the tilt of the ladle. Then, when the distance sensor 6 detects the rising of the feeder 3a, the pouring amount is gradually reduced and the pouring is finished.
