Description

[Technical Field]

[0001] The present invention relates to a moving belt conveyor and a conveying method. [Background technology]

[0002] When transporting goods by belt conveyor, it is common to use a belt conveyor that has a length from the source to the destination. Some belt conveyors have been designed with the ability to extend or tilt the tip for various purposes, such as transporting goods to two locations (the destination and a slightly distant location), reducing the drop at the destination, or quickly retracting the belt conveyor during civil engineering work (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3001491 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-20680 Summary of the Invention [Problem to be solved by the invention]

[0004] However, implementing a mechanism that can extend or tilt the tip of a belt conveyor increases the size of the device, which in turn limits the layout of the conveying path. Therefore, the present invention aims to provide a belt conveyor that can convey to multiple locations with minimal limitations on the layout of the conveying path. [Means for solving the problem]

[0005] The present invention provides a mobile belt conveyor that comprises a belt conveyor body and a stand that supports the belt conveyor body and has a moving means, and that transports objects to multiple locations by moving the entire belt conveyor body back and forth in the longitudinal direction.

[0006] Further, the present invention provides a conveying method in which an object to be conveyed is conveyed to a first place using a mobile belt conveyor including a belt conveyor main body and a gantry that supports the belt conveyor main body and has a moving means, and then the entire mobile belt conveyor is moved in the length direction of the belt conveyor main body to convey the object to be conveyed to a second place.

[0007] Since this mobile belt conveyor can convey the object to be conveyed to a plurality of places by the movement of the entire conveyor advancing and retreating in the length direction of the conveyor, it is not necessary to provide a special expansion and contraction mechanism or the like, and thus the device does not become large-sized.

[0008] This mobile belt conveyor may have at least one of the following features. · It advances and retreats along a predetermined track. · It advances and retreats by traveling on a rail. · The object to be conveyed is ore or powder. · The advancing and retreating movement distance of the mobile belt conveyor is 1 m to 10 m.

Advantages of the Invention

[0009] According to the present invention, it is possible to provide a belt conveyor with less restriction on the layout of the conveying path and capable of conveying to a plurality of places.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and overlapping descriptions are omitted.

[0012] <Configuration> As shown in FIGS. 1 and 2, the mobile belt conveyor 1 includes a belt conveyor main body 2 and a gantry 3 that supports the belt conveyor main body 2. The gantry 3 has wheels (moving means) 3c at its lower part, and the entire mobile belt conveyor 1 moves forward and backward by traveling on the rails 5, 5 that form a straight track. In FIGS. 1 and 2, the right side in the illustrated left - right direction is the front end side in the conveying direction.

[0013] The belt conveyor main body 2 is a straight - type conveyor and has an endless belt 2b wound around pulleys 2a, 2a located at both ends in the conveying direction. The conveying surface (upper surface) side of the belt 2b is supported from the back surface by a plurality of carrier rollers 2c arranged in the conveying direction. The shafts of the pulleys 2a, 2a protrude on both sides in the width direction of the belt 2b and are in contact with the gantry 3 for connection described later.

[0014] The gantry 3 is a frame that supports the weight of the belt conveyor main body 2 and has axles 3d, 3d and wheels 3c as moving means at its lower part to enable the movement of the belt conveyor main body 2. The size of the gantry 3 has at least a length similar to that of the belt conveyor main body 2 and a width wider than at least the width of the belt conveyor main body 2. The gantry 3 supports the weight of the belt conveyor main body 2 by supporting the shafts of the pulleys 2a, 2a. Although not shown, the gantry 3 and the shafts of the pulleys 2a, 2a are respectively connected by bearings.

[0015] At the lower part of the portions near both ends in the length direction of the gantry 3, two axles 3d, 3d and wheels 3c are attached. The length of the axles 3d, 3d is adjusted to the gauge between the two rails 5, 5 so that all the wheels 3c are placed on the rails 5, 5.

[0016] At the rear end side of the mobile belt conveyor 1, two small pedestals 3a and 3b are placed and fixed side by side in the conveying direction on the pedestal 3. A pedestal driving motor 6 is placed on the small pedestal 3a at the rear end side, and this gives power to the axle 3d at the rear end side. A belt driving motor 7 is placed on the other small pedestal 3b, and this gives power to the pulley 2a at the rear end side of the belt conveyor main body 2.

[0017] <Operation> The operation of the mobile belt conveyor 1 will be described. The mobile belt conveyor 1 forms a part of the conveying path of the conveyed material and is used to convey the conveyed material to a plurality of locations. In the present embodiment, as shown in FIG. 3, the belt driving motor 7 is driven to convey the conveyed material 8 such as ore and powder, and the conveyed material 8 is dropped from the front end side of the mobile belt conveyor 1 to the first hopper 9a or the second hopper 9b.

[0018] The mobile belt conveyor 1 of the present embodiment moves forward and backward as a whole in the length direction of the belt conveyor main body 2 by traveling on the linear rails 5, 5 provided in the guide of the conveying path. The moving distance of forward and backward movement (the difference between the existing position at the maximum forward movement and the existing position at the maximum backward movement) may be 1 m to 10 m, may be 2 m to 8 m, or may be 3 m to 6 m. In the state where the mobile belt conveyor 1 has moved backward the most (FIG. 3(A)), since the front end portion of the mobile belt conveyor 1 is located above the first hopper 9a, the conveyed material 8 drops into the first hopper 9a. When the first hopper 9a is full of the conveyed material 8 or the like, when the pedestal driving motor 6 is driven to move the mobile belt conveyor 1 forward (FIG. 3(B)), the front end portion comes to be located above the second hopper 9b, so the conveyed material 8 drops into the second hopper 9b. During that time, at the first hopper 9a side, the dropped conveyed material 8 is collected and emptied to prepare for the next drop of the conveyed material 8. By repeating the reciprocating movement of the mobile belt conveyor 1 due to forward and backward movement, the conveyed material 8 is supplied to the desired hopper. Note that the mobile belt conveyor 1 has a sufficient length so that it can receive the conveyed material 8 from the upstream side even in the state where it has moved forward the most.

[0019] <Effect> This mobile belt conveyor 1 can convey the conveyed object 8 to a plurality of locations by the movement of the entire body advancing and retreating in the length direction of the belt conveyor main body 2. Therefore, there is no need to provide a special expansion and contraction mechanism or the like, and thus the device does not become large-sized, and the limitation of the layout of the conveying path can be reduced. By using the mobile belt conveyor 1, one type of conveyed object can be conveyed to a plurality of locations, or a plurality of types of conveyed objects can be conveyed to separate locations.

[0020] As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited to the above embodiments at all. For example, in the above embodiments, the gantry 3, the wheels 3c, and the rails 5, 5 are shown in a state of being located below the belt conveyor main body 2, but they may be in a state of being located above the belt conveyor main body 2 (hanging method).

[0021] Also, in the above embodiments, the gantry 3 has axles 3d, 3d and wheels 3c, and the mobile belt conveyor 1 is shown running on the rails 5, 5, but it may be a mode of moving by other moving means (for example, a rubber tire method (a configuration including rubber tires and guide rails)). The rubber tire method is preferable in terms of low noise.

[0022] Also, in the above embodiments, the conveyed object is ore, powder, etc., and the mode of dropping this into the hopper is shown, but the conveyed object may be a machine, food, clothing, paper, packaged products, etc., and the conveying destination may be another belt conveyor (including mobile ones), an apparatus in the next process, etc.

Industrial Applicability

[0023] The present invention can be used, for example, for the conveyance of ore or powder.
