[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a conveyor main body for loading and unloading a load that can be moved back and forth by a pair of left and right endless chains that are appropriately driven by driving means in a luggage box on the vehicle body, and moves back and forth on rails. In a freight car with a conveyor device equipped with a stand for preventing load collapse that is possible, a rear door is provided at the rear end of the cargo box, and a side door is provided in front of the cargo box. A feature is that the stand is equipped with a connecting device that can disconnect and connect to the endless chain, and the stand is equipped with an opening / closing door.

[0005]

[Action]

 When leaving the collection point and delivering and collecting packages at the same time, the stand is at the forward end, and the stand is connected to the endless chain by the connecting device, and the luggage is placed on the conveyor body. Are loaded. First, when delivering a package, the rear door of the package is opened and the driving means is driven to move the endless chain backward, so that the package on the conveyor body is delivered from the package.

Next, when the luggage is to be collected, the side door of the luggage box is opened and the luggage is loaded on the conveyor main body in front of the stand. By repeating the delivery and collection of the package, the upright reaches the reverse end. When returning to the delivery station in this state and unloading luggage at the delivery station, after opening the rear door of the luggage box, the connection device disconnects the attachment and the endless chain and opens the opening door of the attachment.

Next, when the endless chain is moved backward, only the conveyor main body is moved rearward while keeping the position of the stand, and the luggage on the conveyor main body is unloaded from the stand with the opening / closing door opened.
