In view of the problems to be solved by the present invention, such a stop and start device for a flow rack is such that a brake plate contacting the lower part of the roller is swingably supported on the upper end of a lever pivotally supported on the frame and the lower end is a drive device. Since the brake plate is rotatably connected to the roller, the brake plate is brought into contact with and separated from the lower part of the roller by the arc motion of the lever tip, and there is a fear that braking and starting of the roller may not be reliable, and the structure becomes complicated. There are some problems.

Therefore, in order to solve such a problem, a moving plate which is composed of a friction member and a plate member and has a length corresponding to a section of a plurality of gravity conveyors, and each moving plate for moving the moving plate up and down. An apparatus for restarting / restarting a conveyed object of a gravity conveyor, which is composed of actuators respectively arranged on the lower side of the plate and driving means for selectively operating the actuators, has already been proposed (Actual exploitation 58-771).
However, in such a gravity conveyor re-starting / stopping device for conveyed goods, it is necessary to provide an actuator for moving up and down and a drive unit for moving in the conveying direction for each moving plate. However, in order to control a plurality of gravity conveyors, the device becomes complicated, and the control mechanism of is also complicated and large-scale.

The present invention has been made in order to solve such a drawback, and in a plurality of gravity conveyors, the configuration is simple, and it is possible to easily manage the recurrence and stoppage of each conveyed product. It is intended to provide a start / stop device.

Means for Solving the Problems In order to achieve the above object, the present invention comprises a moving plate having a length corresponding to sections of a plurality of gravity conveyors, the moving plate being composed of a friction member and a plate member.

The moving plate of the next order from the moving plate on the upstream side is connected by loosely fitting a connecting rod into a long hole formed in the hanging portion of each moving plate.

Action The lowermost moving plate of each gravity conveyor has a connecting pin that engages with the engaging groove of the moving plate, and a lateral channel material with a drive device in the center can slide in the transport direction. Since the moving plates at the uppermost stream are sequentially connected to the moving plates next to each other by loosely fitting the connecting rods into the long holes formed in the hanging parts of each moving plate, the moving plates are self-propelled on the gravity conveyor. When stopping the transported object, the actuator disposed under each moving plate is selectively operated by the driving means to raise the moving plate (the connecting rod is loosely fitted in the long hole of the hanging part). Since each moving plate can be raised independently, the friction member can be brought into contact with the roller to stop the rotation of the roller, and the conveyed object can be stopped. If you want to restart the When is not in the raised position, the moving plate is raised as in the case of stopping, the lateral channel material is moved in the direction opposite to the conveying direction by its drive device, and the moving plate connected by the connecting rod is moved to the upstream side. For example, a rotational force is applied to the roller, and the conveyed product can be started.

Therefore, according to the present invention, the conventional moving means for selectively moving the moving plate up and down and the single driving device can restart and stop the conveyed goods in a large number of sections of the plurality of gravity conveyors. it can.
