走行する移送台車の速度制御装置に関する。[Detailed Description of the Invention] The present invention is a transfer cart used for a pallet transfer device of logistics equipment or a workpiece transfer device of a production line, in particular, a transfer cart is pressed into contact with a rotary drive shaft installed parallel to the rail for running the transfer cart. The present invention relates to a speed control device for a transfer trolley that travels by friction drive of drive wheels.

せられるようになつている。 First, the above-mentioned transfer trolley will be explained with reference to FIG. 1. Reference numeral 1 denotes a rail, and a long rotation drive shaft 2 is provided parallel to the rail 1, and is constantly rotated in the direction of arrow c by a motor (not shown). It rotates at a constant number of revolutions. 3 is a truck with running wheels 10,
Guide wheels 11 allow the vehicle to travel along the rail 1. A drive wheel 6 is provided on the lower surface of the truck 3 and has a horizontal rotation shaft 5 capable of turning horizontally about a vertical shaft 4, and the drive wheel 6 is always pressed against the rotation drive shaft 2 described above. The running thrust of this bogie 3 is obtained by the contact friction between the rotary drive shaft 2 and the drive wheel 6, and its running speed is determined by the angle between the direction of the drive wheel 6 and the axis of the rotary drive shaft 2. The driving wheel 6 is kept at an angle α by a spring (not shown), and a cam roller 8 installed at the tip of an arm 7 fixed to the vertical shaft 4 is a control device installed at a predetermined position on the rail side. When it comes into contact with the bar 9, it can be pivoted about the vertical axis 4.

角度αが増加するので増速し定常走行に至る。 In the above-mentioned trolley equipment, when the trolley 3 travels and comes to the control bar 9, the control bar 9 and the cam roller 8 come into contact with each other, and as it continues to travel, the cam roller 8
The drive wheels 6 are rotated around the vertical axis 4 by rolling along the inclined end surface of the control bar 9, and the angle α between the drive wheels 6 and the rotating drive axis gradually decreases, causing the trolley 3 to decelerate. It will be done. When the cam roller 8 comes to the parallel part of the control bar 9, the bogie 3 reaches its lowest speed. In this state, when the bogie 3 is stopped by a stopper (not shown) provided on the rail side, the drive wheel 6 and the rotary drive shaft 2 are stopped. It is possible to stop the engine with a small amount of thrust remaining at a small angle α. When the vehicle is started to run again, the stopper is released and the vehicle starts running with the remaining thrust. At the same time, the angle α increases, so the speed is increased and steady running is achieved.

なるからである。 In this equipment, the thrust and deceleration force of the trolley 3 are obtained from the contact friction between the drive wheels 6 and the rotary drive shaft 2, so that the thrust and deceleration force change greatly depending on the change in the friction coefficient. For example, if you try to use this equipment in an atmosphere where there is oil or moisture in the surrounding area, and the actual friction coefficient becomes lower than the initially planned friction coefficient due to this atmosphere, the deceleration force may be insufficient and the device may collide with the stopper, or the thrust may be insufficient. This causes the problem that the vehicle does not move forward even if the stopper is released. The remaining thrust has contradictory characteristics with respect to the impact at the time of stopping and the thrust at the time of re-running, and it is difficult to make both of them appropriate just by adjusting the dimension shown by k in the figure.
In other words, in order to reduce the impact when stopping, it is better to reduce k, but k is small (angle α is small).
Therefore, the thrust force sufficient to overcome running resistance such as rolling resistance of the running wheels 10 and guide wheels 11 and move forward cannot be obtained. This is because the apparent deceleration force during deceleration is (deceleration force + running resistance), and the apparent acceleration force during acceleration is (thrust force - running resistance).

はそれだけ不利となる。 Furthermore, if the angle α is made small, not only will the starting of the truck 3 be caused to fail, but the speed of the truck 3 will become slower as the angle α becomes smaller. Therefore, in a production line or the like where quick transfer is required, it is disadvantageous that the cart 3 spends a lot of time traveling slowly along the parallel portion of the control bar 9.

A control bar that comes into contact with the attached cam roller is arranged on the rail side, and a movable plate that is located at the maximum width part of the control bar, protrudes toward the cam roller side, and guides the cam roller continuously with the control bar is pivoted to the control bar. The present invention is characterized in that the movable plate is connected to a drive device for rotating the movable plate, and the drive device allows the movable plate to be moved backward by a control bar.
