[0008] PREVIOUS TECHNICAL

[0009] Asphalt core finishers are used in dam construction applications. R&D work carried out on these machines can make a significant contribution to the economy.

[0010] The low paving quality of asphalt core finishers using current technology compromises construction quality and increases material consumption. In particular, the constant variability in the amount of asphalt coming from the asphalt bunker to the asphalt mold in the asphalt core finisher compromises paving quality. As a result, technical development is required to solve the problem described above.

[0011] PURPOSE OF THE INVENTION

[0012] The purpose of the invention is to continuously measure the amount of asphalt coming from the asphalt bunker to the asphalt mold in the asphalt core finisher using a laser sensor and to automatically adjust the conveyor speed according to the amount of asphalt in the mold. This stabilizes the amount of asphalt used. Furthermore, by adjusting the conveyor speed according to the amount of asphalt in the mold, the quality of the asphalt paving can be regulated and improved.

[0013] Thanks to the invention's fully automated operation, there is no need for personnel, and personnel costs are reduced.

[0023] The system shown in Figure 1 in the asphalt core finisher (100) consists of an asphalt bunker (110), an asphalt mold (120), a laser sensor (130), a conveyor (140), and an automation system (150).

[0024] In the invention; the asphalt bunker (110) where asphalt is stored, the asphalt mold (120) used to shape the asphalt, a laser sensor (130) that continuously measures the distance between the asphalt in the asphalt mold (120) and the sensor's location and provides information to the automation system (150), and a conveyor (140) that automatically adjusts its speed based on the information received from the laser sensor (130).

[0025] In the invention, asphalt is first transferred from the asphalt bunker (110) to the asphalt mold (120) via a conveyor (140). The asphalt in the asphalt mold (120) is discharged, and asphalt paving begins. In the invention, a laser sensor (130) is positioned on the asphalt mold (140). This laser sensor (130) continuously measures the distance between the asphalt on the asphalt mold (120) and the position of the laser sensor (130). After paving begins, as the asphalt mold (120) is discharged, the asphalt level on the asphalt mold (120) decreases. As the asphalt level decreases, the distance between the asphalt and the laser sensor (130) increases. The laser sensor (130) detects this increase in distance and provides information to the automation system (150). With this information, the automation system (150) sends information to the conveyor (140), and the conveyor (140) automatically increases its speed, allowing the asphalt level in the hopper in the asphalt mold (120) to reach the required level. If the asphalt fill level in the asphalt mold (120) has increased, the laser sensor (130) again detects that this distance has decreased and reports it to the automation system (150). In this case, the conveyor (140) automatically reduces its speed, ensuring that the asphalt level in the hopper located in the asphalt mold (120) reaches the required level. If the fill rate in the hopper in the asphalt mold (120) exceeds the upper threshold value, the automation system (150) automatically stops the conveyor (140) and stops the transfer of asphalt to the hopper in the asphalt mold (120). This improves the quality of the asphalt paving. If the asphalt in the hopper inside the asphalt mold (120) falls below the threshold value, the machine automatically stops paving upon detection by the laser sensor (130).
