SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a liner device capable of easily replacing a damaged portion, and at the same time, providing a liner device capable of effectively utilizing rubber. It is an object to provide a liner device. [0005] In order to achieve the above object, the present invention is a liner device for protecting a chute 5 from a collision of a conveyed object, wherein a belt-shaped rubber belt 2 is moved from a supply side to a collection side. The rubber belt 2 is disposed on the inner wall surface of the chute 5 so as to face at least the collision surface 5b of the conveyed object in the transfer path of the rubber belt 2. A liner device is provided. In the above-mentioned liner device, since the rubber belt 2 is arranged facing the collision surface 5b of the chute 5, the rubber belt 2 can protect the chute 5 from collision of a conveyed object. When the rubber belt 2 is damaged with time, the damaged portion of the rubber belt 2 is collected by transferring the belt-shaped rubber belt 2 from the supply side to the collection side by the transfer device 3, and a new rubber belt 2 is formed. It is arranged on the collision surface 5b of the chute 5. As described above, the liner device according to the present invention comprises:
By simply transferring the rubber belt 2 by the transfer device 3, the damaged portion can be collected and a new rubber belt 2 can be disposed, and the replacement operation can be performed extremely easily. Further, since the rubber belt 2 is disposed on the collision surface 5b of the conveyed object of the chute 5 in the transfer path, the rubber belt 2 can be used completely in the transfer direction (longitudinal direction), Effective use of rubber can also be achieved. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1 and FIG.
Shows a liner device including a belt-shaped rubber belt 2 arranged facing the inner wall surface 5a of the chute 5 and a transfer device 3 for transferring the belt-shaped rubber belt 2. Most of the belt-shaped rubber belt 2 (unused portion) is wound around a supply roller 6.
The supply roller 6 is provided outside the chute 5. The rotatable supply roller 6 is provided with a brake mechanism (not shown) so as not to rotate carelessly. Further, a rotatable support roller 7 for supporting the rubber belt 2 is provided above the chute 5. The rubber belt 2 is hung on the support roller 7 so that the rubber belt 2 Turned to the side. The rubber belt 2 moves along the transfer path,
Among the flat inner wall surfaces 5 a of the chute 5, the chute 5 hangs down on the surface on which the conveyed object collides (the conveyed object collision surface 5 b). A rotatable deflection roller 8 is provided below the chute 5 at a position facing the support roller 7.
Is provided. The hanging rubber belt 2 is sent to the collection roller 10 provided outside the chute 5 via the deflection roller 8. The collection roller 10
Can be wound up by being rotated by an electric driving device (not shown), and the used rubber belt is collected. Support roller 7 and deflection roller 8
Are arranged side by side in the width direction as shown in FIG. 2, but the number of these rollers 7 and 8 may be one or two. The liner device 1 pulls out the tip of the unused rubber belt 2 wound around the supply roller 6, hangs it on the support roller 7, and then turns the diverting roller 8 via the collision surface 5b of the chute 5. , And then installed by being attached to the collection roller 10. In addition, in order to use the rubber belt as effectively as possible for initial installation convenience and as much as possible,
As shown in FIG. 1, a pull-out rope 11 may be connected to the tip 2 a of the rubber belt 2, and the end of the rope 11 may be attached to the collection roller 10. The rubber belt 2 preferably has abrasion resistance and flexibility.
Back surface of abrasion-resistant cover rubber of about 40 mm (chute 5
The surface provided with a reinforced canvas having flexibility on the inner wall surface 5a) is exemplified. Further, in order to improve wear resistance, a rubber belt in which a wear-resistant substance such as a ceramic piece is embedded on the surface of the cover rubber may be used.
The length of the belt-shaped rubber belt 2 is, as described later,
As the length of the rubber belt 2 is longer, the unused rubber belt 2 can be transported to the collision surface 5b of the chute 5 many times, and thus can be used constantly for a long period of time. As long as possible, longer is preferred. As shown in FIG. 1, the liner device 1 is configured such that the rubber belt 2
Since the conveyed object is installed at least facing the collision surface 5b of the conveyed object, the conveyed object discharged from the end of the conveyor 15 does not directly collide with the chute 5 but collides with the rubber belt 2. The rubber belt 2 functions as a protection plate for the chute 5. Next, as shown in FIG. 3, the rubber belt 2 damaged by the collision of the conveyed object is transferred from the supply side to the collection side by releasing the brake of the supply roller 6 and driving the collection roller 10. (The direction of the arrow in the figure). Therefore, the unused rubber belt 2 is transported from the supply side, and the collision surface 5 of the chute 5 located in the transport path.
