is moved in the direction of arrow B between the circumferential surface of (see Fig. 1). The conveyor belt 20 that has passed the circumferential surface of the tail roller 32 passes through the belt base 21 and the wavy ribs 2.
Along with the elasticity of 2, to 25, the wavy ribs 22,
, 25 are curved and separated as they pass through the holding crown rollers 41 and 42 in the direction of arrow B, so that they are temporarily expanded in the direction of arrow C, and after passing through the holding crown rollers 41 and 42, the arrow It is contracted back in the D direction (see Figure 5). The conveyor belt 20 has a holding crown roller 41,
42, when the material to be conveyed (for example, sawdust, sand, grains, etc.) falls and is supplied from the supply hopper 45 disposed above through the supply chute 45A, the wavy ribs 22, . . . 25 is arrow C
As the belt expands in the direction of the curve, a large amount of the conveyed object is accommodated between the wavy ribs 22, 25, and then, as it is returned and contracted in the direction of arrow D, the accommodated object is transferred to the belt base. 21 and wavy rib 2
It is sufficiently strongly restrained and held by the elasticity of 2 to 25. The conveyed object accommodated and held by the wavy ribs 22, . . . , 25 is moved by the wavy ribs 22 , . It is conveyed vertically while being held in place. At this time, the wavy rib 2
Since the ribs 2, -, 25 are appropriately inclined in the direction of travel, the conveyed object can be carried along the wavy ribs 22, 25.
. (see Figures 8 and 9). The conveyor belt 20 passes through the curved rollers 34 while containing and holding the conveyed object, and is again moved in the horizontal direction. Thereafter, the conveyor belt 20 passes the circumferential surface of the head roller 31 and begins to move toward the curved roller 35. As the conveyor belt 20 moves along the circumferential surface of the head roller 31 on which the discharge crown is formed,
Similar to when the belt passes over the holding crown rollers 41, 42, the wavy ribs 22, -, 25 are temporarily curved away from each other and expanded due to the elasticity of the belt base 21 and the wavy ribs 22, -, 25.
The conveyed object accommodated and held between the wavy ribs 22 to 25 is easily dropped toward the discharge hopper 55. At this time, the cage roller 51
Since the conveyor belt 20 is rotated while being in contact with the inner circumferential surface of the conveyor belt 20 , the inner circumferential surface of the conveyor belt 20 is intermittently struck, causing the conveyor belt 20 to vibrate. The stored and held conveyed objects are caused to fall toward the discharge hopper 55 more reliably and in a shorter time due to the vibrations. After dropping the conveyed object to the discharge hopper 55, the conveyor belt 20 is moved toward the curved roller 35, passes through the curved roller 35, is moved vertically, and reaches the curved roller 36 at the lowest end. is moved horizontally again. The conveyor belt 20 is moved toward the tail roller 32 after being given an appropriate tension by the snap roller 37 . By repeating the above operations, the conveyor belt device 10 according to the present invention transfers the conveyed object from the lower conveyed object supply section 40 to the upper conveyed object discharge section 50.
It is possible to transport large quantities and with high efficiency along a path extending in a desired direction including the vertical direction. (Modification) Note that in the above description, a discharge crown is formed on the circumferential surface of the head roller 31;
The present invention is not limited to this, and depending on the properties of the conveyed object, the discharge crown may be removed from the circumferential surface of the head roller 31 and only the meandering prevention crown may be used. Further, the cage-shaped roller 51 is connected to the conveyed object discharge section 50.
However, the present invention is not limited to this, and it may be removed depending on the properties of the transported object. . In particular, if a discharge crown is provided on the circumferential surface of the head roller 31, the cage roller 51 may be removed. In addition, the wavy ribs 22, -, 25 are inclined toward the traveling direction of the belt base body 21, but the present invention is not limited thereto; (in the case of an arc shape) or as shown in FIGS. 12 and 13 (in the case where the convex part is V-shaped), it may be made to stand upright on the outer circumferential surface of the belt base 21.
