【Example】

An embodiment of the present invention will be described below with reference to the accompanying drawings.

[0011] As shown in FIG. 1, in order to form an upward transport path 2 for transported objects 1 such as grains and earth and sand, The conveying surface 3a of the first conveyor belt 3 and the conveying surface 4a of the second conveyor belt 4 are mutually connected. They are placed one on top of the other so that they press against each other, and are arranged in a meandering direction vertically upward. . The first and second conveyor belts 3 and 4 are belts made of cloth impregnated with rubber or the like. It is constructed by laminating multiple sheets of wood, and has some elasticity in the longitudinal direction. The first and second conveyor belts 3 and 4 have both ends in the conveying direction. An idle roller for tensioning the belt is installed between the driving roller 5 and the driven roller 6 arranged in the It is spanned through La7. Both longitudinal ends of the upward transfer path 2 are open. one end (lower end) of which serves as a loading port 8 for loading the conveyed object 1, The other end (upper end) serves as an outlet 9.

0012 The first belt located on the inside of the curvature of the meandering part of the first and second conveyor belts 3 and 4 Or, on the back side 10 of the second conveyor belt (3 or 4), there is a belt tangential direction. In order to distribute the tension in the direction perpendicular to the belt, multiple A bearing roller 11 is arranged. These plurality of support rollers 11 are arranged in a straight line. The supporting roller group 12 is It consists of

[0013] FIG. 3 shows a cross-sectional view taken along the line A-A in FIG. 1. As shown in the figure, the support roller 11 is It is provided on the back surface 10 of the meandering portion of the first conveyor belt 3. This bearing roller 11 are three rollers 1 that sandwich the conveyed object 1 while supporting the conveyor belt 3 in a trough shape. It consists of 3. These three rollers 13 are supported by a common shaft 14. Ru. This common shaft 14 extends in the longitudinal direction of the first and second conveyor belts 3 and 4. It is fixed to a rectangular cylindrical frame 15 formed along the length.

[0014] In addition, the first and second conveyor belts 3 and 4 have both widthwise ends pressed together. They are forcibly pressed together by rollers 16. This presser roller 16 is It is pivotally supported by a shaft 17 fixed to a frame 15. Such a presser roller 16 , at appropriate intervals along the longitudinal direction of the first and second conveyor belts 3 and 4. There are multiple locations.

[0015] The operation of this embodiment having the above configuration will be described.

[0016] According to the steeply inclined conveyor having the above configuration, as shown in FIG. 1, the back side 10 of the conveyor belt 3 inside the meandering part is not in a straight line but at a certain angle. It is arranged so that it is changed and becomes a polygon. Therefore, the bell of conveyor belt 3 The tension T in the tangential direction is converted into a component Y in the direction perpendicular to the belt at each support roller portion 11, The resultant force pinches the conveyed object 1 in the transfer path 2.

[0017] The component force Y in the direction perpendicular to the belt is calculated by setting the tension in the tangential direction of the belt to T, and Let θ be the angle between two adjacent sides of the polygon formed by connecting La 11, as follows. I'm going to growl.

[0018] Y/2=T・SIN(θ/2) ∴ Y=T・SIN(θ/2)×2 In other words, the above component force Y has a correlation with the angle θ, and the larger the angle θ, the greater the component force Y. increases, and the pinching force that pinches the conveyed object 1 increases. Use this belt tension T The force that clamps the conveyed object 1 is generated by each support roller section 11, and the resultant force causes the conveyed object 1 to be conveyed. The conveyed object 1 in the path 2 is clamped.

[0019] The conveyed object 1 is held between the conveyor belts 3 and 4 using such belt tension T. This is done alternately along the meandering part inside the meandering part. Therefore, the conveyed object as shown in Fig. 5 A steep slope with a high height at a nearly right angle without providing a spring g to sandwich f. conveyance is realized. Further, the support roller 11 is connected to the meandering conveyor belts 3 and 4. It is not necessary to install it on the outside of the section, but only on the inside of the meandering section, so the number of installations is small. The entire device is simple and low cost.

[0020] Note that the common shaft 14 of the support roller 11 and the shaft 17 of the presser roller 16 are connected to each other. energizing the first and second conveyor belts 3 and 4, respectively, to press them against each other; A biasing means such as a spring g as shown in FIG. 5 may be provided. In this case, the first and the conveyed object 1 between the second conveyor belts 3 and 4, using the belt tension described above. In addition to the clamping force (component force Y), a clamping force by a biasing means such as a spring is added. As a result, the frictional force between the conveyed object 1 and the conveyor belts 3 and 4 increases, and the conveyed object 1 This reduces shedding and improves efficiency.
