Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a belt conveyor device for vertically conveying bulk or powdered materials such as coal and ore.

[Conventional technology]

Conventional vertical belt conveyor devices sandwich loose materials between two conveyor belts that rise vertically, transport them upward at a constant speed, and then move them in a predetermined direction through a fixed upper end discharge port. The conveyor belt is configured to discharge the bulk materials conveyed by the conveyor belt.

[Problem to be solved by the invention]

In this conventional vertical belt conveyor device, since the discharge port at the upper end is fixed facing in a predetermined direction, it is not possible to selectively discharge two or more types of loose materials. If we dare to make this possible, we will install a branch chute and hopper with a built-in switching valve to select the discharge direction between two or more types of receiving conveyor belts or silos facing the discharge port, and install a vertical belt. Once the bulk material is dropped into this hopper from the discharge port of the conveyor, the switching valve is used to switch the branch chute to communicate with the desired receiving conveyor belt or expansion silo, and the bulk material dropped into the hopper is sent through the branch chute to the desired receiving location. It is necessary to install a device for discharging to the side, and in addition, since the discharge port of the vertical belt conveyor is located above the hopper, the height of the vertical belt has to be further increased, and the overall height is increased. The disadvantage is that the structure is complicated and the manufacturing cost is high.

In view of the above-mentioned conventional problems, the present invention has been made to solve this problem, and it is possible to reliably sort and discharge without installing a special device between the discharge port and the plurality of receiving sides. The objective is to obtain a vertical peltoco/pair device that is not bulky and inexpensive.

[Means to solve the problem]

As a means for achieving this, the present invention provides a vertical belt conveyor that stores and holds a conveyor between both conveyor belts and transfers the conveyor in a vertical direction. On the other hand, the upper end is driven so as to be able to turn in the circumferential direction, giving twist to both conveyor belts, thereby making it possible to selectively change the discharge direction of the upper end discharge portion in the circumferential direction.

〔Example〕

Embodiments of the present invention shown in the drawings will be described in detail below.

Reference numeral 1 denotes a cylindrical casing, and a supply side guide link 2 is provided at the lower end of the casing 1, a discharge side guide link 3 is provided at the upper end, and a plurality of intermediate guide links 4 are provided in the middle thereof in the horizontal direction.

Reference numeral 5 denotes a vertical belt conveyor, in which two sets of conveyor belts 6.6, which are endless conveyor belts, are connected to the vertical space l of the casing 1, similar to known vertical belt conveyors.
The belts facing inside of both conveyor belts 6.6 are the rising sides 6a, 61, and the belts facing outside are the descending sides 6b, 6b. The ends are pressed against each other by guide rollers 71.7a, and guide rollers 7b, 7b are arranged so as to form a storage section 8 for conveying conveyed objects A such as bulk items in the center, and two sheets are formed together. On the other hand, the lowering sides 6b, 6b are guided by guide rollers 7es7e. Furthermore, the upper and lower folded ends of both conveyor belts 6.6 are guided in the horizontal direction by the guide rollers 7a, 7b, 7a, respectively, thereby forming a supply section 9 at the lower end and a discharge section 10 at the upper end.

Reference numeral 11 denotes a fixed roller 2-support stand, which is fixed to the supply side guide link 2, and is fixed to the fixed roller support stand 11.
It is attached to rotatably support guide rollers 7a17b and 7c that guide the set of conveyor belts 6.6.

Reference numeral 12 denotes a rotating roller support stand, which is installed so as to rotatably support guide rollers 7&, 7b, and 7e that guide the conveyor belt 6.6 in the same way as the fixed roller support stand 11. A wheel 12m is rotatably pivotally attached to the intermediate guide link 4, and is fitted to a rail 4a formed on the inner periphery of the intermediate guide link 4 so as to be rotatable within the intermediate guide link 4.

Reference numeral 13 denotes a rotating roller support stand for the discharge side, which, like the above-mentioned turning roller support stand 12, has a guide roller of 7 m.
, 7b, 7c, and is rotatably mounted within the discharge guide ring 3 by wheels 13a that fit into the rails 3a on the inner circumference of the discharge guide link 3.

Reference numeral 14 denotes a swing drive mechanism, in which a swing drive motor 16 is attached to one side of the discharge side guide link 3, and a pinion 15 is connected to this. On the other hand, a large driven gear 17 is fixed on a support frame 13b erected from the rotating roller support stand 13,
The driven gear 17 is rotatably engaged with the pinion 15.

Note that 18 is a hood, which is attached to cover the discharge section 10. 19 is a gear cover, and 20 is a receiving side conveyor, which are disposed at a plurality of locations at intervals in the circumferential direction below the discharge section 10.

With this configuration, the swing drive motor 16
When the pinion 15 is started and the pinion 15 is rotated, the driven gear 17 meshed with the driven gear 17 rotates, so that the rotating roller support 13 for the discharge side, which is integrated with the driven gear 17, has its wheels 13 and the rails of the discharge side guide link 3. To rotate and run on 3a,
Rotating roller support base 13 Rotates in the direction of the solid line arrow in Figure 3. However, both conveyor belts 6.6 of the vertical belt conveyor 5 have their lower end portions fixed to the fixed roller supports 1.
1 to the supply side guide link 2, both conveyor belts 6.6 are twisted, and accordingly, the rotating roller support base 12 of the intermediate guide ring 4 portion also rotates as shown by the arrow in FIG. 6.6 is the axis XX of the fixed roller support 11 at the lower end, and the axis i@IY of the rotating roller support 12 of the intermediate guide ring 4 section.
- The rotating roller support base 13 of the discharge section 10 at the upper end rotates in the axis @2-2 direction. As a result, the discharge section 10 rotates at the same time as the rotation roller support base 13, so that it can be selectively rotated onto a desired receiving conveyor 20 of the plurality of receiving conveyors 20 disposed in the circumferential direction. can. Next, if the conveyed object A is supplied from the supply section 9 and the vertical belt conveyor 5 is moved, the conveyed object A is
c) It is stored in the accommodation section 8 of the ascending sides 6a, 6a of both belt conveyors 6.6, ascends by both belt conveyors 6.6 in a twisted state, is conveyed to the discharge section 10, and is conveyed to the desired receiving side conveyor 20. Object A can be sent out. In this way, the forward and reverse rotation of the swing drive motor 15 causes the discharge section 10 to swing left and right as shown by the actual arrow or dotted line arrow in FIG. for,
The axis zz of the rotating roller support stand 13 of the discharge section 10 can be oscillated left and right by about 90 degrees to the maximum extent, and the roller can be selectively supplied to the receiving conveyor 20 at a plurality of locations.

〔Effect of the invention〕

As described above in detail with respect to the embodiments, the present invention allows the rotation angle of the upper end discharge section to be freely changed by twisting the conveyor belt while the conveyor belt is stored and held between both conveyor belts, and can be stopped at any position. A large number of conveyors or silos on the receiving side can be arranged in any position, and the receiving side can be freely accommodated.

In addition, there is no need to install a special sorting switching device between the discharge section and the receiving side, the discharge section can be directly opposed to the receiving side, and feeding can be performed reliably, and the vertical belt conveyor does not become bulky. It is possible to provide a vertical belt conveyor device that is robust and inexpensive.
