Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a conhair device that is capable of conveying objects to be conveyed in any direction on a plane and in a vertical direction. be.

<Prior Art> Today, when conveying articles in a plane, a so-called belt conveyor is generally used in which the conveyed article is placed on a belt and conveyed.

The belt conveyor that is normally used is a straight conveyor, and when conveying objects in a curved manner using such a straight conveyor, the conveying direction is changed appropriately using multiple linear conveyors, and the conveyed object is It is being transported to a predetermined position while being transferred.

For this reason, if the object to be conveyed is bulk material such as coal or ore, there are problems such as spillage or dust generation during transfer from one conveyor to another, contaminating the working environment. there were.

In order to solve the above problem, the belt is rolled into a cylindrical shape,
Cylindrical conveyors have been developed in which objects to be conveyed can be enclosed and conveyed.

As mentioned above, this cylindrical conveyor has a belt rolled into a cylindrical shape, so that the conveyor itself can be bent with a predetermined curvature, and therefore the conveyed object can be conveyed along a curved path to the destination. be. In addition, by enclosing the conveyed object in a cylindrical belt and conveying it, there is no risk of spillage or dust generation during conveyance.

In addition, when conveying goods on steep slopes including vertical ones, conveyors with fins attached to the belt, packet conveyors with packets attached to belts or chains, or two belts overlapped and conveyed objects between the belts are used. Polymerized belt conveyors, etc., which clamp and transport objects, have been developed.

Among these, polymerized heat converting hair is easy to maintain, has a small installation area, and since the conveyed object is conveyed by sandwiching it between two belts, there is no risk of contaminating the work environment such as generation of dust. It has the following advantages.

The above-mentioned cylindrical conveyor performs horizontal and gently inclined conveyance, and can also convey arbitrary curves! It is a conveyor device developed for the purpose of Ifa conveyance, and a polymerization belt conveyor is a conveyor device developed for the purpose of steep slope conveyance including vertical conveyance.

<Problems to be Solved by the Invention> In the above-mentioned conventional technology, the object to be transported is transported in any horizontal direction including a gentle slope, and also vertically transported from the ground to a desired height to reach a predetermined position. In the case of conveyance, it is necessary to combine a cylindrical conveyor and a polymeric belt conveyor, each of which is constructed separately.

For this reason, the cost of the conveyor device increases, and since a plurality of driving means are required for each conveyor device, there are problems such as an increase in the running cost of the conveyor device.

In addition, when conveying objects, it is necessary to transfer them from a cylindrical conveyor to a polymerization belt conveyor, or from a polymerization belt conveyor to a cylindrical conveyor. When transferring from one conveyor to another conveyor, there is a risk that the advantages of each conveyor described above may be lost, such as spillage of cargo or generation of dust that contaminates the working environment.

Further, the belt used in the cylindrical conveyor must have the property of being easily rolled into a cylindrical shape, and the belt used is of the same quality as the belt used in commonly used belt conveyors. However, the belt used in the polymerization belt conveyor maintains the polymerization state of the two belts by applying tension to the two belts that is higher than that applied to a normal belt conveyor. Therefore, it is necessary to have high tensile strength and high rigidity.

As described above, the belts in cylindrical conveyors and polymerization belt conveyors are each used under unique conditions. Therefore, in order to combine the above-mentioned conveyors to function as one conveyor device, it is necessary to apply appropriate tension to the belt, maintain the cylindrical state of the belt, and maintain the overlapping state of the belt, etc. It becomes necessary.

In other words, if excessive tension is applied to a cylindrical conhair belt, the belt will not be able to maintain its cylindrical state, and the belt on the conveying side that encloses the conveyed object will become fan-shaped, and the belt on the return side will not be able to maintain its cylindrical state. It will be in a folded state. Therefore, there is a problem in that troubles are likely to occur on the conveyance route.

In addition, if the tension applied to the belt of the i-combined belt conveyor becomes too small, it will not be possible to apply sufficient clamping force to the conveyed objects in the steeply inclined conveyance section, and as a result, the overlapping state of the belts will be maintained. There is a problem in that cargo cannot be carried out and cargo spills from the conveyance section.

It's okay if it's only moderate.

Therefore, the tension applied to the belts 1 and 2 can be adjusted as appropriate depending on the properties of the objects to be transported, such as their specific gravity.

The belts 1 and 2 used in the conveyor device configured as described above have a tensile strength in the longitudinal direction of the belt, and
It is desirable that the material also has high extensibility in the middle direction. For this reason, the belts 1 and 2 of this embodiment are constructed by forming a tensile strength layer in the center of the belt and providing high tensile strength layers on both sides thereof.

In this way, the belt 1 is attached to the holding roller 13 in the cylindrical portion 8.
The belt 1 is formed into a cylindrical shape, and objects to be transported are enclosed inside the belt 1 and transported in the direction of arrow a, which is the transport direction.

The cylindrical conveying section A can be bent at an arbitrary angle of 90 degrees or less with a predetermined bending radius R.

The bending radius R can be set as R≧100D, where D is the diameter of the cylindrical portion when the belt is formed into a cylindrical shape.

A transition section 5 is formed between the cylindrical conveyance section A and the polymerization conveyance section C.

The bell) l is transferred from the cylindrical portion 8 of the cylindrical conveying portion A through the converting portion 7 while being released from the pressure bonding at both ends in the width direction. As shown in FIG. 3(C), the belt 1 has a recess formed in the center of the belt 1 by rollers 14 a and 14 b forming the transfer roller 14 in the transition section 5, and the conveyed object is placed in the recess.

At the end of the second curved conveyance section 11, the overlapping state of the belt 1.2 is released, and the belt 1 is wound around the return roller C from the tail roller lb and returned in the direction of the drive roller 1a. The conveyed object transferred onto the belt 2 is conveyed to the cylindrical conveyance section B through the transition section 6. Transition section 6
The belt 2 at the transition point 5 is the same as the belt 1 at the transition section 5 described above
It is transferred by the transfer roller 4 similarly.

Further, the belt 2 in the cylindrical conveying section B is gradually formed into a cylindrical shape by the holding roller 3 in the same manner as the belt 1 described above in the converting section 7 and the cylindrical section 8, and is also formed into a cylindrical shape.
