【産業上の利用分野】この発明は、一対のテーパローラ
間にループ状の搬送用ベルトを螺旋状に張設して成る所
謂スパイラルコンベアに関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called spiral conveyor formed by spirally stretching a loop-shaped carrying belt between a pair of taper rollers.
【０００２】[0002]

軌跡で移送するものである。2. Description of the Related Art As shown in FIGS. 4 and 5, a spiral conveyor is basically constructed by spirally stretching a loop-shaped conveyor belt 3 between a pair of tapered rollers 2 and 2.
The one taper roller 2 is rotationally driven by the motor 90, and the transported object placed on the transport belt 3 is transported in a spiral locus.

うにして円滑に移動せしめられることとなる。In this case, in the driven state, a moving force acts on the conveyor belt 3 inward (in the direction of arrow A shown in FIG. 4), so that a smooth transfer of the object to be conveyed is realized. The locking means 4 as shown below is provided. That is, as shown in FIG. 6, the thick portion 40 is formed on the entire outer peripheral portion of the conveyor belt 3, and the upper and lower rotating bodies 42 and 43 groups are formed on the outer peripheral side fixed portion F of the conveyor belt 3. It is rotatably provided, and as shown in the figure, the upper and lower rotating bodies 42 and 43 sandwich the base end portion 41 of the thick portion 40. Therefore, the transport belt 3 is in a movement blocking state in the direction of the arrow A, and the transport belt 3 can be smoothly moved by rotating the upper and lower rotating bodies 42 and 43. .

互間から抜けるという現象が発生するからである。However, the conventional spiral conveyor described above has a problem that it is difficult to transfer a large weight of an object to be conveyed upward. This is because, in this type of conveyor, if the pulling force (pulling force) of the taper roller 2 to the upper side of the conveyor belt 3 is increased in order to transfer a large weight object to be conveyed, This is because the moving force toward the arrow A side (inner side) increases, and the increased moving force causes the conveyance belt 3 to come out from between the upper and lower rotating bodies 42 and 43.

も発生する。In addition, if the moving force of the conveying belt 3 inward is increased as described above, apart from the above problem, the portion in the vicinity of the supporting structure of the conveying belt 3 is damaged in a short period of time, and the conveyor as a whole is made. There is also a problem that the life of the product is shortened.

(Operation of the invention according to claim 1) In this spiral conveyor, the upper surface of the taper roller is pulled up and the lower taper roller is pushed up to move the carrying surface side of the carrying belt. Even if the driving force is large, the tensile force acting on the conveyor belt does not increase unlike the one described in the section of the prior art.

従来の技術の欄に記載したもののように増大しない。Therefore, the inward moving force of the conveyor belt is not so large, and as a result, the load on the conveyor belt is not large. (Operation of the invention according to claim 2) In this spiral conveyor, since the conveyor belt side is moved in such a manner that the upper taper roller pulls up and the lower taper roller pushes up, the total rotation of both taper rollers is increased. Even if the driving force is large, the tensile force acting on the conveyor belt does not increase unlike the one described in the section of the prior art.

となる。Therefore, the inward moving force of the conveyor belt 3 does not become large unlike the one described in the section of the prior art, and as a result, the conveyor belt 3 has the upper and lower rotating bodies 42,
The phenomenon of coming off from between 43 will hardly occur. In other words, even a large weight object can be easily transferred upward. Further, in this spiral conveyor, the moving force to the inner side of the conveyor belt 3 does not become large unlike the one described in the section of the prior art, so the burden load on the conveyor belt does not become large, and as a result, the conveyor as a whole does not Will have a long life.
