DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for dropping an object to be conveyed from a first conveyor to a second conveyor with a height difference provided between a discharge end of a first conveyor and a discharge end of a second conveyor. The present invention relates to a transfer device for transferring a transferred object.

[0002]

2. Description of the Related Art Generally, a transfer device for a transferred object is formed in a chute provided between a first conveyor and a second conveyor having a height difference, and is carried out from a discharge end of an upper first conveyor. The conveyed object is dropped on the conveyor belt at the carry-in end of the lower second conveyor and connected.

If the conveyed object falls on one side of the conveyor belt of the second conveyor, the conveyer belt may meander, or the rollers of the conveyor belt at the position where the conveyed object drops intensively may be worn. The problem that it hastened had arisen.

[0004] Therefore, conventionally, the conveyed object loaded from the first conveyor is applied to a tiltable damper whose upper end is pivotally supported, and the falling trajectory is adjusted while buffering, so that the desired movement of the conveyor belt of the second conveyor is achieved. It was going to drop to the position.
Adjustment of this fall trajectory is performed by changing the inclination angle of the damper by turning the handle for adjusting the inclination angle of the damper provided on the back side of the damper while the worker visually checks the falling position of the transferred object. The handle is stopped when the transferred object falls to a desired position.

Further, the operator can manually adjust the inclination angle of the damper based on empirical data determined by the type and shape of the transferred object and the speed and angle of the conveyor without directly observing the drop position of the transferred object. In some cases, such a method was adopted.

[0006]

When the type, shape, etc. of the object to be dropped is changed, the falling position of the second conveyor on the conveyor belt is changed, so that the inclination angle of the damper is adjusted each time. However, the manual operation as described above has a problem that it takes a lot of time and work efficiency is deteriorated.

Accordingly, the present invention has been devised to solve the above-mentioned conventional problems, and its purpose is to automatically change the type and shape of the object to be dropped according to the change. An object of the present invention is to provide a transferred object transfer device capable of adjusting a falling trajectory of a transferred object by adjusting an inclination angle of a damper.

[0008]

In order to solve the above-mentioned problems,
The present invention relates to a conveyed object provided with a height difference between an unloading end of a first conveyer and an inflow end of a second conveyer, wherein the conveyed object is dropped from the first conveyer to the second conveyer and transited. In the transfer device, an ideal drop passage is provided in the middle of a fall flow path for a conveyed object formed between the discharge end of the first conveyor and the carry-in end of the second conveyor, and is pivotally supported on a shaft portion of an ideal fall flow path. A stone box that receives a transported object falling on it, forms a deposition section having a repose angle, and tilts due to the movement of the apex angle of the repose angle, and a falling locus of the transported object by detecting the tilt of the stone box And a damper provided between the discharge end of the first conveyor and the stone box for buffering an object to be conveyed from the discharge end and guiding the stone box to the stone box with a fall trajectory at an arbitrary angle. Means,
Damper control means for controlling the damper means when the fall trajectory detection means detects that the stone box is tilted to form a pile of repose angle along the ideal fall flow path on the stone box; It is provided with.

According to the present invention, when the type, shape, etc. of the object to be dropped is changed and its falling trajectory is changed, the apex angle of the angle of repose of the accumulation section is moved and the stone box is moved. By tilting, the falling trajectory detecting means detects that the stone box has tilted, and the damper controlling means controls the damper means, whereby the falling trajectory of the transferred object can be automatically adjusted.

First, the configuration of the transferred object transfer device according to the present invention will be described.

As shown in FIG. 1, the transferred object transfer device 1 is formed in a chute 2 provided between a first conveyor 10 and a second conveyor 20 having a height difference. The conveyed object 3 such as coal or iron ore carried out from the carry-out end 11 of the one conveyor 10 is dropped on the conveyor belt 22 of the carry-in end 21 of the lower second conveyor 20 to be connected. I have.

The transferred object transfer device 1 is located between an unloading end 11 of the first conveyor 10 and an unloading end 21 of the second conveyor 20 in an ideal falling flow path 4 of the transferred object 3. In addition, a stone box 5 for temporarily receiving and dropping the transferred object 3 is provided to be tiltable. Further, a drop trajectory detecting means 6 for detecting the tilt of the stone box 5 and detecting the drop trajectory of the transported object 3 is provided, and is provided between the discharge end 11 of the first conveyor 10 and the stone box 5. Is provided with a damper means 7 for buffering the transferred object 3 from the discharge end 11 and guiding the transferred object 3 to the stone box along a falling locus of an arbitrary angle. Further, a damper control means 8 for controlling the damper means 7 when the falling trajectory detecting means 6 detects that the stone box 5 has tilted is provided.

As shown in FIG. 3, the stone box 5 has an ideal falling flow path 4, that is, an upper part of a shaft core 14 which is bridged from both sides (in the drawing, front and back sides) on the center line in the width direction of the chute 2. , Is fixed so as to tilt with the rotation of the shaft core 14, and the fixed position is the center line portion of the stone box 5 in the left-right direction in the drawing. That is, the stone box 5 is supported in a balance shape, and is configured to be flat in a balanced state. The stone box 5 has a wear-resistant liner layer made of ceramic or the like on its surface. In addition, Stone Box 5
Is formed in a substantially rectangular shape, and a weir member 15 formed of a square pipe is provided at both ends in the left-right direction in the figure in parallel with the axis 14. By the weir member 15, a certain amount of the transported object 3 that has dropped is deposited, and a buffer layer composed of the transported object 3 is formed on the stone box 5,
The transferred object 3 does not directly hit the surface of the stone box 5, and the surface can be protected. Then, the transported object 3 is further dropped and deposited to form the deposition section 16 having a repose angle.

The fall trajectory detecting means 6 has a torque arm 17 which rotates with the shaft core 14 at one end of the shaft core 14, and a load cell 18 for detecting the rotation of the torque arm 17 is provided at a tip end thereof. I have.

As shown in FIG. 2, the damper means 7 is provided diagonally below the carry-out end 11 of the first conveyor 10 and has an upper end connected by a pin and is rotatable.
9 mainly comprises a hydraulic cylinder 23 provided on the back side of the damper 19 for adjusting the inclination angle of the damper 19.

The damper 19 has a wear-resistant liner layer 33 made of ceramic or the like formed on the surface thereof, and a frame body 34 for supporting and fixing the liner layer 33. The section is formed in a rectangular shape so that the side faces the discharge end 11 side. At the lower end and the center, a shelf 3 is formed to form a buffer layer by the transported object 3.
1 and a weir member 32 are formed. Further, a pin 24 extending in the horizontal direction is fixed to the upper end, and the pin 24 is pivotally supported by a pivot groove 26 formed at the upper end of the support member 25 and having an open top. A plurality of the pivot grooves 26 are formed, and the inclination angle of the damper 19 can be diversified by moving the pivot position of the damper 19. The distal end of the rod 35 of the hydraulic cylinder 23 is pin-connected to the substantially central rear surface of the damper 19 in the height direction.
4 is tilted and oscillated.

That is, the damper means 7 buffers the transferred object 3 from the discharge end 11 by the damper 19, and guides the transferred object 3 to the stone box 5 with an arbitrary falling trajectory by adjusting its inclination angle.

The mechanism for tilting and swinging the damper 19 is not limited to the hydraulic cylinder 23, but may be another mechanism such as an electric motor via a gear.

The damper control means 8 includes a drop trajectory detection means 6
A control device 27 is provided between the control unit 27 and the damper means 7. The control device 27 receives a detection signal when the fall trajectory detection means 6 detects that the stone box 5 has tilted. The hydraulic cylinder 23 of the damper means 7 is expanded and contracted to tilt the damper 19 to a desired inclination angle, and the transferred object 3 is dropped on the axis 14 of the stone box 5 so that the angle of repose along the ideal falling flow path 4 is reduced. The deposition section 16 is formed.

A buffer box 36 is provided between the stone box 5 and the carry-in end 21 of the second conveyor 20 to temporarily stop the dropped conveyed object 3 and then drop it to reduce the speed thereof. . In addition, a window 37 for monitoring the inside of the chute 2 is formed in the upper part of the chute 2.

Next, the transferred object transfer device 1 according to the present invention.
The operation will be described along the flow of the transferred object 3 described above.

The transferred object 3 is thrown into the chute 2 from the discharge end 11 of the first conveyor 10, first collides with the damper 19, is reflected and falls down. Then, it is temporarily stored on the stone box 5.

At this time, the transferred object 3 is placed in the ideal falling channel 4
Is deposited along the stone box 5, the apex of the angle of repose does not deviate from the axis 14 and the stone box 5 is flattened without tilting. State will be maintained. Then, the transported object 3 uniformly flows down from the apex portion of the stacking portion 16 to the peripheral portion of the stone box 5, drops to the carry-in end 21 of the second conveyor 20 below, and drops intensively to a part. Can be prevented.

If the falling trajectory of the transported object 3 is eccentric from the ideal falling flow path 4 (for example, the left side in FIG. 1), the deposition section 16 formed on the stone box 5 Since the apex angle of the repose angle shifts from the axis 14 to the drop position side (left side) of the transferred object 3 and the weight balance is lost, the stone box 5 tilts to the left around the axis 14. With this tilt, the torque arm 17
The rotation of the object 3 is detected by the load cell 18 to detect the displacement of the falling trajectory of the transferred object 3. That is, by detecting the rotational force of the torque arm 17, the deviation of the transferred object 3 from the normal weight balance is detected, and the deviation of the falling locus is detected.

The detection value detected by the falling trajectory detecting means 6 is transmitted to the control device 27 which is the damper controlling means 8.
Is sent from the control device 27 to the hydraulic cylinder 23 of the damper means 7. And the rod 25
Expands and contracts (retracts in the above case) and changes the inclination angle of the damper 19 to adjust the fall trajectory of the transferred object 3. When the stone box 5 becomes flat, the hydraulic cylinder 23
To stop. Here, the transferred object 3 comes to fall along the ideal falling flow path 4.

As described above, the falling trajectory of the transferred object 3 is
By modifying the ideal falling flow path 4,
Can uniformly flow down from the apex portion of the stacking section 16 to the periphery of the stone box 5 and fall down to the carry-in end 21 of the second conveyor 20 below, and can be prevented from being concentrated on one part and concentrated. The meandering of the belt 22 and the early consumption of the rollers of the conveyor belt 22 can be prevented.

Further, even if the type and shape of the transferred object 3 change during the operation and the falling trajectory shifts, the falling trajectory of the transferred object 3 is automatically detected by the drop trajectory detecting means 6 as described above. And the damper 19 is expanded and contracted by the damper control means 8, so that the falling locus of the transferred object 3 can be automatically corrected.

Further, the weir member 1 on the stone box 5
5 is formed only on a pair of opposing sides, so that when the type of the transferred object 3 is changed, the previous transferred object 3 can be easily passed from the stone box 5 through the portion where the dam member 15 is not formed. Can be dropped. When dropping the previous transferred object 3, the stone box 5
May be formed so as to be rotatable by 180 degrees, and the object 3 may be completely dropped by being rotated.

The falling trajectory detecting means 6 is provided with a load cell 18 for detecting the rotation of the torque arm 17, but is not limited to the load cell 18 and may be replaced with another mechanism such as a limit switch. You may.

[0032]

In summary, according to the present invention, even if the type, shape, etc. of the object to be dropped is changed and its falling trajectory is changed, it is detected and automatically detected. Since the falling trajectory can be adjusted along the ideal falling flow path, the working efficiency can be improved, and the excellent effect of preventing the meandering of the conveyor belt and the early consumption of the rollers of the conveyor belt can be exhibited.
