At the same time, the outer surface of the friction plate 3 is brought into contact with the friction wheel 8.

Next, when the ropes 1a and 1b are respectively run in the directions of the arrows, the guide roller 5 rotates in the direction of the arrow A in conjunction with the running of the ropes 1b. Then, the friction wheel 7 on the same support shaft 6 as the guide roller 5 rotates in the same direction as the guide roller 5, and the friction wheel 8 in contact with the friction wheel 7 rotates in the direction of arrow B. On the other hand, since the internal cleaning material 2 contacts the rope 1b, the cylindrical body 4 is always biased in the running direction of the rope 1b, that is, in the direction of contact with the friction wheel 8, and the magnetic force of the magnet in the friction plate 3 and/or the friction plate The rope 1b rotates in the direction of the arrow C due to the frictional force of 3 in conjunction with the rotation of the friction wheel 8, and the rope 1b is continuously cleaned by a cleaning material, that is, a brush 24 inside the cylinder 4. Incidentally, the inclination of the cylindrical body 4 caused by contact with the friction wheel 8 is corrected by the rollers 14. Further, the cleaning material soiled by cleaning the rope can be removed from the cylinder, washed with detergent, etc., and then used repeatedly.

(Effects of the invention) The rope conveyor cleaning device of the present invention has the configuration and operation described in detail above, so that it is possible to attach the cylindrical body to which the cleaning material is attached to the rope, and to attach a brush or sponge body etc. to the cylindrical body. Cleaning materials can be easily attached and detached for excellent workability.
In addition, since the rotating means of the cylinder is composed of a simple means that is linked to the running of the rope, it is possible to continuously clean the rope conveyor while it is in operation without using any external power, and the rope is always kept clean. This has the advantage that the conveyed articles can be kept in place to prevent contamination of the conveyed articles.
