Description

[Detailed description of the invention] This invention significantly reduces the height of the elevator body, even if the packet is installed facing outward, as in elevators with the packet facing inward. This invention relates to an elevator that allows for efficient conveyance work with less noise and smoother movement.

A pair of flat pulleys mounted vertically in the elevator main body are equipped with packets at equal intervals, and an endless flat belt attached outward is rotatably suspended, and the rotating action of the packets transports the transported object. Elevators that transport objects to a predetermined height are well known.

By the way, in the elevator with the outer set as mentioned above,
Normally, the rotation locus of the packet is located farther outside than the rotation locus of the flat belt with respect to the axis of the child pulley, and it rotates in a whirlpool, so the width of the elevator body becomes larger.
As a result, the weight increases and more workers are required for installation work, and many accidents occur when the flat belt slips.This makes maintenance management difficult, and the conveyed objects are thrown by packets. This is a serious problem as the head of the elevator becomes large due to the fact that the electric motor that rotates the flat belt is installed at the top of the elevator, and this causes the height of the elevator to become larger compared to the amount of transport. It has several drawbacks, and these drawbacks have not been improved to date.

In view of the above, the present invention has been developed with the V
A belt is arranged, and on the outer periphery of the V-belt there are a number of mounting brackets that are integrally bent so that the mounting pieces on both sides are inside the rotation locus of the V-belt and close to both the left and right sides of the V-belt. The packets are attached at approximately equal intervals, and the packets are attached to the respective attachment pieces facing outward, so that even if the packets are attached to the V-belt facing outward, the This is an attempt to provide an elevator that achieves an increase in transport volume without noise, perhaps by reducing the height of the main body, making it lighter and heavier, and making the structure simpler and cheaper.The structure of the present invention is attached below. A preferred embodiment shown in the drawings will be described.

Reference numeral 1 denotes an elevator main body for lifting objects to be conveyed from below to above, and a pair of V-boots J-2 and 3 are rotatably mounted on shafts at upper and lower positions within the elevator main body 1. At the same time, one V-belt 4 is suspended around the pair of ``boo'' J-2 and 3.

Attachment pieces 6, 6 on both sides are attached to the outer circumference of the V-belt 4.
The V-belt 4 is rotated so that it passes through a rotational trajectory B that is inner than the rotational trajectory A, and a large number of mounting brackets 5, which are integrally bent and formed so as to be close to both the left and right sides of the V-belt 4, are spaced at approximately equal intervals. At the same time, the respective mounting pieces 6,
The packet 7 is mounted on the V-belt 6 so as to be located on the outside, and with this configuration, the outer circumferential surface 7a of the packet 7 is approximately flush with the outer surface of the V-belt 4 or protrudes slightly outward.

Reference numeral 8 is a tensioning hopper attached to the bottom side of the elevator main body 1, and 9 is a carry-out gutter provided at the upper part of the elevator main body 1.

Next, the operation of the present invention will be explained.

Now, if one of the pulleys 2 and 3 is rotated by an appropriate means and the material to be transported is placed in the loading hopper 8, the material to be transported will be rotated in the direction of the arrow in FIG. The packets 7... carry out a lifting operation in which they are scooped up and transported one by one and transported out from the upper transport gutter 9.

By the way, during the above-mentioned lifting operation, a large number of packets 7... are rotated by the V-belt 4, so the V-belt 4 rotates accurately under small power without causing any slip phenomenon. The rotation locus B of the mounting pieces 6, 6 on which the packets 7 are attached while carrying out the conveying action is located inside the rotation locus A of the V-belt 4, and is also provided close to both the left and right sides of the V-belt 4. Therefore, the centrifugal force on the rotating V-belt 4 becomes very small, and the V-belt 4 does not swing irregularly, which reduces noise during rotation and allows a large number of packets 7... - Large-capacity objects can be transported easily.

In short, the present invention uses the V-belt 4, which does not cause the slip phenomenon due to small power as described above, to easily rotate a large number of packets 7. Compared to the V-belt 4, the outer periphery of the V-belt 4 has a rotation locus B of the mounting pieces 6. A large number of mounting brackets 5 are integrally bent so that they are located inside the rotation locus A of the V-belt 4 and close to both the left and right sides of the V-belt 4.
are attached at approximately equal intervals, and since the packets 7 are attached to the respective mounting pieces 6, 6 facing outward, the rotation radius of the packets 7 is made small and the elevator main body 1
Not only can the height of the belt be significantly reduced, but also the centrifugal force acting on the V-belt 4 during conveyance work can be reduced to prevent the V-belt 4 from swinging irregularly, thereby preventing noise during conveyance. In addition to being able to prevent wear of the V-belt 4, it is also possible to efficiently transport a large amount of objects.
