Hereinafter, the operation of the present invention will be described in detail.                     

Figure 5 is a side view showing the operating state of the automatic conveyor belt load detection device of the tripper running in accordance with the present invention.

Before explaining the operation of the present invention, as shown in Fig. 2, it can be seen that the belt at the tripper end point is significantly lifted in the carrier roller 8 due to the belt tension in the state that the transport is not loaded. have.

In the above state, as shown in FIG. 3, even when the idle gear 10 is driven from the driven and driven gears 14 and 15 by the force of the tension spring 20 and the tripper 22 is moved back and forth, This is not passed.

One process of discharging the cargo is completed and the tripper 22 is moved to the next lower chute 3 in the absence of load for the next process, at which time the cargo is discharged at a time interval (cab guess). If the transport does not arrive until the tripper 22 arrives in the next lower chute (3) is to perform the normal operation.

However, if the transport is loaded on the conveyor belt 4 before the tripper 22 arrives in the lower chute 3, the conveyor belt 4 is driven by the load of the transport, as shown in FIG. The weight sensor roll (7) goes down,

As the weight sensing roll 7 is operated downward, the idle gear 10 is gear-coupled to the drive gear 14 and the driven gear 15.

Since the tripper 22 is already traveling, the drive gear 14 transmitted by the driving belt 13 from the driving sheave 12 of the driving wheel 11 is idling. The driven gear 15 is rotated by the gear coupling operation of the gear 10.

In addition, when a load is loaded and transported temporarily in a lump (for example, remaining amount or cleaning light residue), the weight sensing roll (7) is lowered only at a temporary moment. If the weight piece 16 is first injured by the winding action of the wire rope 19 and then the conveyor belt 4 is returned to the unloaded state, the condition that the tripper 22 can continue running with the gear connection in the original state is restored. Provide.

However, as described above, when the transport material of the subsequent process is loaded continuously, the idle gear 10 is gear-coupled to the driving gear 14 and the driven gear 15 to rotate the wire rope 13 by transmitting a rotational force ) Is wound around the driven gear sheave 15a of the driven gear 15 so that the first weight piece 16 rises first and the stopper 16b formed on both sides thereof is the first to second wire sheaves 27a and 28a. The synergistic action is stopped by contacting the limit plate 25 formed at the lower end of the brackets 27b and 28b.

When the synergistic action of the second weight piece 16 is stopped, the second weight piece 17 is pulled by the wire rope 19 which is continuously wound on the driven gear sheave 15a, and is thus moved. Therefore, when the proximity sensor 18 fixed to the conveyor frame 24b detects the upward movement of the second weight piece, the movement of the tripper 22 and the driving of the conveyor belt 4 are stopped, and the worker takes the following action by receiving the signal. Will be taken.

As described above, according to the present invention, a large accident such as wheel departure, tripping of a tripper, burning of a driving motor, etc. may occur due to an overload caused by a shut-off caused by the transport of the post-process in the situation where the tripper is moved. It is effective in preventing the driver's and worker's mental burden on safety accidents and improving worker's work efficiency.
