And a moving part for clamping the belt 122 between the anti-rolling plate 16 and the anti-rolling roll 18.

The base member 12 is fixedly installed on the frame structure 110 of the belt conveyor 100 via the installation bracket 13 and is spaced apart from the return belt 122 by a predetermined distance.

In the present embodiment, the fixing plate 14 is installed extending in the traveling direction of the return belt 122 at the intermediate point of the base member 12. The fixing plate 14 is fixed to the frame structure 110 by the installation bracket 13 is installed on the outer end like the base member 12.

The fixed plate 14 is horizontal to the ground. Accordingly, the fixing plate 14 has a structure that is opened at a predetermined angle with the return belt 122 disposed to be inclined with respect to the ground. That is, the interval between the fixed plate 14 and the return belt 122 is gradually narrowed along the reverse direction of the return belt 122.

Two guide bars 20 are formed in pairs and are installed at both ends of the base member 12, respectively. The guide bar 20 has a long hole 22 is formed in the longitudinal direction along the front surface. One end of the guide bar 20 is installed at the base member 12, and the other end thereof extends along the traveling direction of the return belt 122. In addition, in the present embodiment, the guide bar 20 extends in a direction parallel to the return belt 122 and is disposed at a predetermined angle with the fixing plate 14 like the return belt 122.

The anti-roll roll 18 is rotated by the rotation axis 19 extending from the center is fitted into the long hole 22 of the guide bar 20. In addition, the rolling prevention roll 18 has a structure in which the rotating shaft 19 moves along the long hole 22 so as to move in the forward or reverse direction with respect to the return belt 122.

In this embodiment, the roll preventing rolls 18 are provided in pairs on both ends of the rotation shaft 19 in pairs. The size, installation position, and the like of the anti-rolling roll 18 are not particularly limited to be variously deformable. The anti-roll roll 18 may be made of a material having a high frictional force with the belt 120 and may be made of a rubber material in this embodiment.

Accordingly, when the anti-roll roll 18 moves in the reverse direction of the return belt 122 along the long hole 22 of the guide bar 20, the gap between the belt 120 and the fixing plate 14 gradually decreases. The anti-roll roll 18 is to press the return belt (122). Therefore, the return belt 122 is pressed and fixed between the anti-roll plate 16 and the anti-roll roll 18 placed below.

The anti-rolling plate 16 is a flat plate structure, is fixedly installed at an angle corresponding to the inclination angle of the return belt 122 at the bottom of the return belt 122. The anti-rolling plate 16 is disposed at a predetermined angle with the fixing plate 14 similarly to the return belt 122. In this embodiment, the anti-rolling plate 16 may be made of a rubber material so as to increase friction with the belt 120.

On the other hand, the moving part is installed on the support member 30 and the front end of the support member 30 and the support member 30 rotatably coupled to the rotation shaft 19 of the rolling prevention roll 18, the rotation is placed on the return belt 122 It comprises a one-way roller 32 to be. The one-way roller 32 is configured to rotate during the forward movement of the return belt 122 and not rotate in the reverse direction.

Accordingly, the one-way roller 32 and the support member 30 serve to push and move the anti-roll roll 18 when the return belt 122 proceeds in the reverse direction. Therefore, the anti-roll roll 18 is moved in the reverse direction, such as the return belt 122 is sandwiched between the fixed plate 14 and the anti-roll plate 16 of the lower return belt 122.

In this embodiment, the one-way roller 32 may be installed at an intermediate point of the rotation shaft 19 to apply a uniform force to the rotation shaft 19.

The one-way roller 32 is a structure in which a ratchet and a ratchet gear are installed therein and are rotated in only one direction. Since many techniques are already disclosed for this one-way rotating structure, detailed description thereof will be omitted.

In this embodiment, the one-way roller 32 is lowered by its own weight together with the support member 30 so as to be in close contact with the return belt 123 to have sufficient frictional force.

Here, the device 10 is to increase the fixing force for the return belt 122 in a state in which the rolling prevention roll 18 is in close contact between the fixing plate 14 and the return belt 122. To this end, the apparatus 10 installs a fixed gear 34 on the rotation shaft 19 of the rolling prevention roll 18, and the rack plate 36 engaged with the fixed gear 34 on the fixed plate 14. ) Is formed. The fixed gear 34 is installed at the center of the rotation shaft 19 which is a position corresponding to the fixed plate 14. Accordingly, the fixed gear 34 meshes with the rack gear 36 while the anti-roll roll 18 presses the return belt 122, thereby preventing the roll-off of the anti-roll roll 18 from occurring. (122) The fixing force can be increased.

Hereinafter, the operation of the apparatus 10 will be described with reference to FIG. 3.

As the belt of the belt conveyor 100 proceeds in the forward direction (A direction), a normal raw material transfer operation is performed.

That is, in FIG. 3, the one-way roller 32 is rotated in close contact with the return belt 122, and the anti-roll roll 18 also moves toward the end of the guide bar 20 by the moving direction and the weight of the return belt 122. do. The anti-roll roll 18 is moved to the gap between the fixed plate 14 and the anti-roll plate 16 is opened at a predetermined angle is located.

Therefore, the return belt 122 is not pressed by the anti-roll roll 18 or the anti-roll plate 16 to move freely and to feed the raw materials normally.

In this state, when the belt 120 is damaged or pushed back, the belt 120 moves in the reverse direction (B direction), and the belt 120 is pushed by the apparatus 10 being operated to fix the belt 120. This prevents it from moving backwards.

That is, when the belt 120 is pushed and moved in the reverse direction, the one-way roller 32 placed on the return belt 122 is not rotated and moved in the reverse direction as the return belt 122 by the friction force with the return belt 122.

Accordingly, the one-way roller 32 and the support member 30 move together with the return belt 122 to push up the rotation shaft 19 in the reverse direction. As such, the force transmitted to the one-way roller 32 during the reverse movement of the return belt 122 is transmitted to the rotation shaft 19 through the support member 30 so that the anti-roll roll 18 installed on the rotation shaft 19 is the guide bar 20. It moves in the reverse direction along the long hole (22) of. As a result, the anti-roll roll 18 enters between the fixed plate 14 and the return belt 122, which are gradually narrowed.

Therefore, the return belt 122 is pressed by the anti-roll roll 18 and is pressed and fixed between the anti-roll roll 18 and the anti-roll plate 16. Accordingly, the return belt 122 is no longer pushed in the reverse direction. At this time, the fixed gear 34 installed on the rotary shaft 19 of the rolling prevention roll 18 is engaged with the rack gear 36 of the fixed plate 14 to increase the fixing force. Accordingly, the belt can be prevented from being pushed out or released in the reverse direction.

On the other hand, when the belt 120 is normally operated again, the return belt 122 also proceeds in the forward direction, and the anti-roll roll 18 is rotated together with the return belt 122. When the anti-roll roll 18 is rotated, the fixed gear 34 installed on the rotating shaft 19 is rotated with respect to the rack gear 36 of the fixed plate 14 so that the anti-roll roll 18 is gradually fixed to the fixed plate 14. And downwards between the barrier plate 16.

Between the fixing plate 14 and the rolling prevention plate 16 is gradually opened in the forward direction of the return belt 122, the pressing force of the rolling prevention roll 18 against the return belt 122 is gradually reduced. Therefore, the return belt 122 is not pressed by the anti-roll roll 18 or the anti-roll plate 16 is free to move normally.

While the illustrative embodiments of the present invention have been shown and described, various modifications and alternative embodiments may be made by those skilled in the art. Such variations and other embodiments will be considered and included in the appended claims, all without departing from the true spirit and scope of the invention.
