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 comprising a loop-shaped conveying belt spirally stretched between a pair of tapered rollers.

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 basically consists of a loop-shaped conveying belt 3 spirally stretched between a pair of tapered rollers 2, 2.
One of the tapered rollers 2 is rotationally driven by a motor 90 to transport an object placed on the transport belt 3 along a spiral trajectory.

うにして円滑に移動せしめられることとなる。In this device, in the driving state, a moving force acts on the conveying belt 3 inward (in the direction of arrow A shown in FIG. 4), so in order to realize smooth conveyance of the object, for example, A locking means 4 as shown below is provided. That is, as shown in FIG. 6, a thick portion 40 is formed over the entire outer circumference of the conveyor belt 3, and upper and lower rotary bodies 42 and 43 groups are formed on the outer circumferential fixed portion F of the conveyor belt 3. As shown in the figure, the base end 41 of the thick portion 40 is held between the upper and lower rotating bodies 42 and 43, respectively. Therefore, the conveyor belt 3 is in a movement-prevented state in the direction of the arrow A, and the conveyor belt 3 is smoothly moved by rotating the upper and lower rotating bodies 42 and 43 described above. .

互間から抜けるという現象が発生するからである。However, the above conventional spiral conveyor has a problem in that it is difficult to transport objects of large weight upward. This is because in this type of conveyor, in order to transfer a large weight object, when the upward pulling force (pulling force) of the conveyor belt 3 by the tapered roller 2 is increased, the conveyor belt 3 is This is because the moving force toward the arrow A side (inward) increases, and this increased moving force causes a phenomenon in which the conveying belt 3 comes off from between the upper and lower rotating bodies 42 and 43.

Another problem arises in that the lifespan of the battery is shortened.

As shown in FIGS. 1 and 2, the spiral conveyor of this embodiment basically includes a spirally formed frame 1 and tapered rollers 2 rotatably supported at the upper and lower parts of the frame 1, respectively. A loop-shaped conveyor belt 3 is stretched spirally along the frame 1 between the tapered rollers 2 and 2, and a loop-shaped conveyor belt 3 is provided on the outer circumferential side of the conveyor belt 3 in a driving state. A locking means 4 (see FIG. 3) that pulls the outer peripheral portion outward and only prevents it from moving inward; motors 90, 90 that rotationally drive both of the tapered rolls 2, 2, respectively; It is comprised of a pedestal 5 that supports the frame 1 in a predetermined posture.

The upper surface position of the roller 12 is set to correspond to the upper surface position of the tapered rollers 2, 2. A pair of bearing units (not shown) are disposed at the upper and lower parts of the frame 1, respectively, and these bearing units rotatably support the tapered rollers 2, 2.

2, 43. That is, in this embodiment, the conveyor belt 1 can move through the thick portion 4 without being blocked from moving in a predetermined direction by the large number of upper and lower rotating bodies 42 and 43.
0 and the upper and lower rotating bodies 42, 43 are engaged with each other to prevent the conveyor belt 4 from moving inward. In this embodiment, the upper and lower rotary bodies 42, 43 are constructed of bearings, the inner race of the bearing is supported and fixed, and the outer race is the rotating part.

が大きくても搬送用ベルト３に作用する引張力は従来の
技術の欄に記載したもののように増大しない。Since the spiral conveyor of this embodiment is constructed as described above, the conveying surface of the conveying belt 3 is moved in such a manner that it is pulled up by the upper taper roller 2 and pushed up by the lower taper roller 2. Therefore, even if the total rotational driving force of the tapered rollers 2, 2 is large, the tensile force acting on the conveying belt 3 does not increase as described in the prior art section.

となる。Therefore, the inward moving force of the conveyor belt 3 is not as large as that described in the prior art section, and as a result, the conveyor belt 3 is moved closer to the upper and lower rotating bodies 42,
43, the phenomenon of falling out of the mutual gap almost never occurs. In other words, even heavy objects can be transported upwards without difficulty. In addition, in this spiral conveyor, the inward moving force of the conveyor belt 3 does not increase as much as described in the conventional technology column, so the load on the conveyor belt does not increase, and as a result, the conveyor as a whole will have a long lifespan.

(Effect of the invention as claimed in claim 1) In this spiral conveyor, the force for moving the conveyor belt inward is not as large as that described in the prior art column, and as a result, the load borne by the conveyor belt is large. Since this does not occur, the life of the conveyor as a whole is extended. (Effect of the invention according to claim 2) In this spiral conveyor, the force for moving the conveyor belt inward is not as large as that described in the prior art column, and as a result, the conveyor belt moves upward and downward. Since the phenomenon of the rotating bodies falling out from between each other is less likely to occur, a heavy object to be transported can be smoothly transported upward.
