Generally speaking, a linear motor is used and the primary side of the motor is installed along the entire track in order to transport carts loaded with cargo, etc., but this is prone to problems such as increased equipment costs. 9,
#i In a product unloading or processing assembly line, etc., it is sufficient to stop the motor at each stage, so there is no need to install the motor next to it over the entire length, and the motor only applies to each stage. The next side of the motor is installed. The secondary C platform RA is driven at the stage, and travels to the next stage by inertia due to the acceleration force applied.
In this stage I, the brake is applied, and then the motor is sent to the next stage I again.

なる等の問題かめる。However, in this case, if a power outage occurs while the bogie is in operation, the bogie will run only by inertia and the braking force is lost at the stage stop.The bogie will not necessarily stop at the stage stop; It often stops in the middle of the process.
Even if the next side of the motor of each stage is energized, there is no driving force for the cart that has stopped in the intermediate area, and therefore it is necessary to take measures such as moving it to the stage by human power. Think about the problem.

以下本発明を図面に示す実施例に基づいて説明する。For this reason, in consideration of the above-mentioned case, measures have been attempted such as tilting the approximate center of the track between adjacent stays slightly higher, but in most cases, the weight of the cart reaches the stage due to the weight of the cart in the event of a power outage. Many problems remain.0 The present invention was made in view of this problem, and even if there is a power outage while the trolley is in operation, the motor next to the stage is always automatically stopped and energized again. It is an object of the present invention to be able to reliably restart the vehicle and resume operation without causing any hindrance to the operation of the vehicle.The present invention will be described below based on embodiments shown in the drawings.

What does the above-mentioned pulse and switching during normal operation mean? J4 is equipped with a stop pulse generating means that applies a braking pulse to the winding of the primary side 1 so as to decelerate and stop the transport vehicle 2. This causes a power outage. At this time, the transport vehicle 2 continues to travel due to the accumulated kinetic energy, and when it reaches the next stage, that is, the primary side 1, it is decelerated and stopped by the secondary side 1.
