A conveyor is a device used to transport a variety of goods. There are various types of conveyors, such as a belt conveyor, a screw conveyor, a bucket conveyor, a chain conveyor, a roller conveyor, and a trolley conveyor. Among them, the belt conveyor transfers the conveyed material by using a belt rotating in an infinite orbital manner. Since the power loss due to friction is very small and the installation structure is simple, it is widely used in many fields.

The above-mentioned belt conveyor is mainly used for conveying aggregate, cement, iron ore, etc., as disclosed in the patent documents of the following prior art documents. However, in the belt conveyor according to the related art, there is a problem that a part of the conveyed aggregate, cement, or iron ore is attached to the belt and is transported to fall down to the floor to generate falling objects. In particular, a significant amount of fallen objects are accumulated in the lower portion of the lower support roller of the belt conveyor, because the conveyance which has been attached to the lower support roller of the belt conveyor falls and falls. As described above, when falling objects are generated, not only the transportation efficiency is reduced, but also a great amount of manpower is consumed to treat falling objects, and even a heavy equipment is required to be mobilized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view of a conveying apparatus for conveying a falling object according to an embodiment of the present invention, FIG. 2 is a front view of a conveying apparatus for conveying a falling object according to an embodiment of the present invention, Means and a side view of the scraper.

1 to 4, a falling device for conveying a conveyor according to the present embodiment is provided below a conveyor 800 and includes a base 110 and a conveyor 800 from both sides of the base 110, A base frame 100 for collecting fallen objects F falling from the conveyor 800, a guide part 200 provided on the base frame 100, a guide part 200 (300) reciprocating in one direction (A) and the other direction (B) along the base frame (100), and a moving means And is reciprocally moved in one direction A and the other direction B together with the moving means 300 and rotates with respect to the moving means 300 when moving in the one direction A so that one end is in contact with the base portion 110 While the fallen object F is conveyed to the one direction A while the other is moving in the other direction B, And one end of the scraper 400 is spaced apart from the base portion 110. [

The apparatus for conveying a falling object on a conveyor according to an embodiment of the present invention is provided in a conveyor 800 and collects and processes fallen objects F generated in the conveyor 800. [ Here, the conveyor 800 may be a belt conveyor, and the conveyance conveyed by the conveyor 800 may be, for example, aggregate, cement, iron ore, and the like.

The base frame 100 collects the fallen objects F generated in the conveyor 800 and is provided on the lower side of the conveyor 800. The base frame 100 includes a base 110 disposed below the conveyor 800 in parallel with the longitudinal direction of the conveyor 800 and a base 110 extending from both sides of the base 110 in the direction of the conveyor 800 And includes two side portions 120 (see FIG. 2). At this time, the side portions 120 are fixed to both sides of the conveyor 800, so that the whole of the base frame 100 can be fixed to the conveyor 800. As a whole, the base frame 100 can be formed in a "concave" shape when viewed from the cross section, thereby collecting fallen objects F falling from the conveyor 800. [ For example, as shown in FIG. 1, a conveyed object may be attached to a belt 810 in a conveyor 800, and then dropped and fall into the belt 810 to form a falling object F. FIG. In particular, below the belt 810 of the conveyor 800, at least one first support roller 820 for supporting the belt 810 may be provided, wherein the fallen matter F mainly comprises a first support roller 820 It can fall from the belt 810. These fallen objects F are collected on the inside of the base frame 100 naturally without falling to the ground or the like. The fallen objects F collected in the base frame 100 are processed by the scraper 400, and a detailed description thereof will be described later.

2) serves to guide the reciprocating movement of the moving means 300 and is provided on the side portion 120 of the base frame 100. The guide portion 200 (see FIG. Here, the guide portion 200 protrudes inward from the side portion 120 (the center of the base frame 100). At this time, the guide part 200 extends along the longitudinal direction of the side part 120. For example, the guide portion 200 may be an angle with a "V" The guide portion 200 is inserted into the groove 330a of the conveying roller 330 provided in the moving means 300 so that when the conveying means 300 reciprocates, ).

The moving means 300 supports the scraper 400 so that the scraper 400 reciprocates along the longitudinal direction of the base frame 100. Here, the moving means 300 is guided by the guide portion 200 at both sides thereof (see Fig. 2), and is movable along one direction (A, the front end direction of the base frame 100) The rear end of the base frame 100) (see Fig. 1). 3 to 4, the moving means 300 includes a plate-shaped body 310, a first fastening portion 320 provided at one side of the body 310 and fastened to the scraper 400, And a conveying roller 330 provided on both sides of the main body 310 and into which the guide unit 200 is inserted. At this time, the first fastening part 320 can be hinged to the second fastening part 420 of the scraper 400 through the rotation shaft S, the fastening pin 430, and the like. In addition, the conveying roller 330 is formed with a recessed groove 330a, and the guide portion 200 is inserted into the groove 330a (see FIG. 2). Therefore, when the moving means 300 reciprocates, the conveying roller 330 can move along the guide portion 200 and rotate.

The scraper 400 (see FIG. 1) transports the fallen objects F collected in the base frame 100 in one direction (A). The scraper 400 is rotatably coupled to the moving means 300 on the basis of the rotation axis S so that the scraper 400 rotates in one direction A along the longitudinal direction of the base frame 100 together with the moving means 300, (The front end direction of the base frame 100) and the other direction (the rear end direction of the base frame 100). 3 to 4, the scraper 400 includes a plate 410 for transferring the fallen matter F and a second fastening part 420 fastened to the plate 410. As shown in FIG. The second fastening part 420 of the scraper 400 is hinged to the first fastening part 320 of the moving means 300 through the rotation shaft S and the fastening pin 430, To the connecting means (600). Since the second fastening part 420 of the scraper 400 is hinged to the first fastening part 320 of the scraper 400 with respect to the rotation axis S as described above, And can be rotated with respect to the moving means 300 on the basis of the rotation axis S. 3, the scraper 400 rotates with respect to the moving means 300 when the scraper 400 is moved in the one direction A, and one end thereof contacts the base portion 110. As shown in FIG. 4, when the scraper 400 is moved in the other direction B, the scraper 400 is rotated with respect to the moving means 300 so that one end thereof is spaced apart from the base portion 110. That is, when the scraper 400 is moved in the one direction A, one end of the scraper 400 contacts the base 110, and when the scraper 400 moves in the other direction B, . Therefore, the scraper 400 moves the fallen objects F collected in the base frame 100 to the one direction A only when the scraper 400 moves in the one direction A, and remains in the base frame 100 when moving in the other direction B The falling object F is not transported in the other direction B. As a result, the scraper 400 can transfer the fallen object F only in one direction A, and finally, the fallen object F is pushed out from the front end of the base frame 100 to drop the fallen object F at a predetermined position For example, on a floor or other conveyor). However, when one end of the scraper 400 contacts the base 110 when the scraper 400 is moved in the one direction A, it does not mean that the scraper 400 is physically in perfect contact, Which is capable of transferring substantially the falling matter F, including a change due to, for example,

The moving means 300 may include a first stopper 340 and a second stopper 350 to prevent the scraper 400 from rotating beyond a predetermined angle with respect to the rotational axis S. [

3, when the scraper 400 is moved in the one direction A, one end of the scraper 400 is in contact with the base 110, (400) is prevented from rotating. The first stopper 340 protrudes in one direction A from the rotary shaft S and is disposed at the lower end of the moving means 300 and is disposed in the other direction B as compared with the scraper 400, It is possible to prevent the scraper 400 from rotating due to contact with the portion of the scraper 400 which is located at one end side of the scraper 400 with respect to the rotation axis S when the movable scroll 400 moves in the one direction A. [ For example, the first stopper 340 may be formed by extending the first fastening portion 320 of the moving means 300 downward.

4, when the scraper 400 is moved in the other direction B, the second stopper 350 is moved to a position where one end of the scraper 400 is spaced apart from the base 110, Thereby preventing the scraper 400 from rotating. Specifically, the second stopper 350 is provided at the upper end of the moving means 300 and is disposed in the other direction B as compared with the scraper 400, and when the scraper 400 moves in the other direction B, It is possible to prevent the scraper 400 from rotating by contacting the sloped portion of the scraper 400 with the other side of the scraper 400 with respect to the rotation axis S.

When one end of the scraper 400 contacts the base 110 and the scraper 400 moves in the other direction B when the scraper 400 moves in the one direction A, For example, the driving unit 500 and the connecting unit 600 shown in FIG. 1 may be used.

The driving unit 500 provides a driving force for reciprocally moving the moving unit 300 and the scraper 400 in the one direction A and the other direction B and the connecting unit 600 is provided between the driving unit 500 and the scraper 400 400 to the scraper 400 to transmit the driving force of the driving unit 500 to the scraper 400. At this time, the connecting means 600 is connected to the other end of the scraper 400 (the upper end of the second fastening part 420) which is opposite to the one end of the scraper 400 (see FIGS. The rotating shaft S of the scraper 400 is disposed between one end of the scraper 400 and the other end of the scraper 400. When the tension of the connecting means 600 acts on the other end of the scraper 400, 400 may rotate about the rotation axis S.

3), when the scraper 400 is moved by the driving force of the driving unit 500 (see FIG. 3), the connecting means 600 applies tension to the other end of the scraper 400 in the one direction A , The scraper 400 may be rotated with respect to the rotation axis S so that one end of the scraper 400 contacts the base 110. Conversely, when the scraper 400 is moved in the other direction B by the driving force of the driving unit 500 (refer to FIG. 4), the connecting means 600 applies tension to the other end of the scraper 400 in the other direction B So that the scraper 400 can be rotated with respect to the rotation axis S so that one end of the scraper 400 is separated from the base frame 100.

Specifically, the connecting means 600 may be coupled to the upper end of the second fastening portion 420 of the scraper 400 through the connecting piece 610. At this time, the connecting piece 610 is connected to both ends of the connecting means 600 so that the tension of the connecting means 600 can be received from both the one direction A and the other direction B. The connecting piece 610 is fastened to the second fastening part 420 and the connecting pin 440 so as to be rotatable with respect to the second fastening part 420. Thus, the connecting piece 610 can always be arranged parallel to the direction in which the tension of the connecting means 600 acts.

1, the connecting means 600 includes the front end of the base frame 100, the lower side of the base frame 100, the driving unit 500, and the rear end of the base frame 100 from the scrapers 400. [ And then extend back to the scraper 400 again. That is, the connection means 600 may extend to both sides of the scraper 400 so as to surround the base frame 100. At this time, a second supporting roller 620 for supporting the connecting means 600 may be provided on the front end of the base frame 100, the lower side of the base frame 100, and the rear end of the base frame 100.

The driving unit 500 may be provided with a sprocket 510 and the connecting unit 600 may be a chain engaged with the sprocket 510. However, it is needless to say that the use of the chain as the connecting means 600 is merely exemplary and not necessarily limited thereto, and all known means such as wires can be used as the connecting means 600. [

The driving unit 500 may reciprocally move the moving unit 300 and the scraper 400 in one direction A and the other direction B at regular time intervals. That is, the moving means 300 and the scraper 400 reciprocate each time a predetermined amount of the falling matter F is collected in consideration of the amount of the falling matter F collected in the base frame 100, F) can be processed.

When the moving means 300 is disposed at the front end of the base frame 100 or at the rear end of the base frame 100, a control unit for switching the driving direction of the driving unit 500 may be provided. By this control unit, the moving means 300 and the scraper 400 can reciprocate within the base frame 100 only. At this time, the control unit can use all known means, but can use a limit switch, for example.

In addition, the tension holding means 700 may be provided to pull the connecting means 600 to maintain the tension of the connecting means 600. The driving force of the driving unit 500 can be effectively transmitted to the scraper 400 through the connecting unit 600 by maintaining the tension of the connecting unit 600 by using the tension holding unit 700, Can be prevented from being attracted to the base portion 110. The tension holding means 700 includes a tension holding roller 710 connected to the connecting means 600 and a tension adjusting device 720 for adjusting the pulling force of the connecting means 600 by the tension holding roller 710 . At this time, the tension adjusting device 720 can be screwed to the support member 130, one end of which is coupled to the tension retention roller 710 and the other end that supports the base frame 100. The tension regulating device 720 can adjust the force by which the tension retention roller 710 pulls the connecting means 600 by changing the distance between the tension retention roller 710 and the supporting member 130. [

FIGS. 5 to 9 are side views showing a process of operating a falling device for conveying a conveyor according to an embodiment of the present invention. Referring to FIG. 5, an operation process of the device for conveying a falling object according to the present embodiment will be described.

First, as shown in Fig. 5, the fallen objects F falling from the conveyor 800 are collected in the base frame 100 while the conveyor 800 is operated. At this time, the moving means 300 and the scraper 400 are disposed at the rear end of the base frame 100, and the driving unit 500 does not transmit the driving force to the scraper 400 so that the scraper 400 and the moving means 300 It is stopped.

6 to 7, when a predetermined amount of the falling objects F is collected in the base frame 100, the driving force of the driving unit 500 is transmitted to the scraper 400 through the connecting means 600 So that the scraper 400 and the moving means 300 move in one direction (the front end of the base frame 100). At this time, the connecting means 600 applies tension to the other end of the scraper 400 in the one direction A, so that one end of the scraper 400 contacts the base 110, ). Thereafter, the scraper 400 is moved in the one direction A while contacting the base portion 110 while being prevented from rotating further by the first stopper 340. One end of the scraper 400 contacts the base 110 to transfer the fallen object F in one direction A and finally the fallen object F is pushed out from the front end of the base 110, (F) at a predetermined position.

8, when the scraper 400 and the moving means 300 are moved to the front end of the base frame 100, the driving direction of the driving unit 500 is switched by the control unit. 9, the driving force of the driving unit 500 is transmitted to the scraper 400 through the connecting unit 600 so that the scraper 400 and the moving unit 300 move in the other direction B, (The rear end of the main body 100). Since the connecting means 600 provides a tension to the other end of the scraper 400 in the other direction B so that one end of the scraper 400 is separated from the base 110 by a scraper 400 rotate. Then, the scrapers 400 move in the other direction B while being separated from the base 110 in a state where the scrapers 400 are prevented from rotating further by the second stoppers 350. Since the one end of the scraper 400 is separated from the base 110 and moves in the other direction B as described above, the fallen object F remaining on the base frame 100 is not transferred in the other direction B. Therefore, the scrapers 400 can transfer the fallen objects F only in one direction (the front end of the base frame 100), and consequently, the fallen objects F can be collected or delivered only to predetermined positions.

The apparatus for conveying a drop material on a conveyor according to an embodiment of the present invention collects a fall object F of a conveyor 800 using a base frame 100 and then uses the scraper 400 reciprocating to move the fall object F It is possible not only to increase the overall transport efficiency but also to reduce the cost by eliminating the need for additional manpower consuming or heavy equipment to be used for processing the falling objects F. [

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
