摘要： PROBLEM TO BE SOLVED: To provide a working vehicle capable of reducing rapid torque fluctuation transmitted to a drive mechanism when a clutch is engaged with the drive mechanism of a working vehicle and being excellent in safety and operation.
SOLUTION: The drive mechanism of a working vehicle comprises a major speed change lever sensor 111, a direction switch 102, a trunnion axis angle sensor 64, a clutch switch 120, and a running control controller 110 which is a control means for controlling a speed change gear on the basis of detected values. When the clutch is disengaged, the speed change gear is controlled to lead into a neutral standstill state. When the clutch is switched from the disengaged state to an engaged state in the drive mechanism, the speed change means is gradually accelerated at a beginning stage up to speed at a targeted speed change position if switching of the clutch is detected. Subsequently, speed changing rate is increased, and the speed changing rate is controlled to reduce before reaching to the speed at the targeted speed change position.

摘要： PROBLEM TO BE SOLVED: To enable the detection of the three-dimentional position and attitude of a plane to be performed by a speedy and inexpensive device. SOLUTION: The height in the z-axial direction of three marks 6a to 6c provided on a plane 5 is obtained on the basis of the output from a height detecting sensor 9, and the position in the x-y axial direction of each of the marks 6a to 6c is obtained on the basis of the photograph data of a camera 8 which has photographed these marks 6a to 6c and the preset teach data. The 3-D position of a plane is arranged to be obtained by computational processing on the basis of the values obtained in above-mentioned ways. Therefore, as the detection by the height detecting sensor 9 and the photographing by the camera 8 can be performed in a short time, the detection of the 3-D position and attitude is performed in a short time. Furthermore, as providing the height detecting sensor 9, camera 8 and a means performing computational processing on the basis of the height in the z-axial direction and the position in the X-Y direction of each mark 6a to 6c is structurally sufficient, the 3-D position and attitude of the plane 5 can be detected by an inexpensive device.

摘要： PURPOSE:To prevent producing defective casting by providing the judging means to judge whether a core is properly placed in a main mold or not based on the detected result from detecting means. CONSTITUTION:By the control of a controller 6 based on a core model signal and the detected result of a position sensor 5, a traveling member is moved to a specific position, a distance to main mold face is detected by a distance sensor 4. Subsequently, by the control of a controller 6 based on the core model signal and the detected result of the position sensor 5, a distance to the specific position of the core is detected by the distance sensor 4. Based on a traveled quantity of the traveling member and detected result from the distance sensor 4, the relative position between the main mold and core accommodated in the main mold is operated by the controller 6, it is compared to the reference value set beforehand. The operated result by the controller 6 is compared to the reference value, when the difference is smaller than the threshold value set beforehand, it is judged core placement is properly executed.

摘要： PROBLEM TO BE SOLVED: To provide a work vehicle for safely traveling in a place such as a slope on which an attitude of a work vehicle body happens to become unstable during traveling. SOLUTION: Ground angles in the longitudinal and lateral direction are detected by inclination sensors 105a and 106a. Risk is arithmetically determined from an attitude and the speed of the work vehicle. Thereby, a traveling speed is reduced according to the risk by using a continuously variable transmission mechanism 23 automatically controlled by a control controller 110. When the risk is remarkably high, a target speed is set to zero, and travel of the work vehicle is stopped.

摘要： PROBLEM TO BE SOLVED: To make a casting thin and reduce flash by heightening the accuracy for accommodating a core into a main mold. SOLUTION: After a core is accommodated in a main mold by a core accommodating robot, a relative position of the main mold and the core accommodated in the main mold is detected by a relative position detecting means (S3). Based on the detection result, the degree of deviation of the relative position of the main mold and the core accommodated in the core against the relative position of the main mold and the core in a proper position is calculated by a deviation value calculating means (S4), so that a teaching data of the core accommodating robot is corrected by the core accommodating position correcting means according to the calculated deviation value (S8). During the core accommodating operation after the correction, the main mold and the core are corrected into a proper position relationship. Thereby, the position accuracy for accommodating the core into the main mold is heightened, so as to make a casting thin and reduce the flash.
