2. Description of the Related Art For example, in a tire manufacturing factory, a tire molded into a predetermined shape must be transported to the next step for the next treatment. In this case, it is generally used by connecting a large number of belt conveyors, a row of tires is formed on this belt conveyor, sequentially,
Will be transported. However, when the tires are conveyed by the belt conveyor in this way, the length of the belt conveyor must be secured according to the number of tires to be conveyed, and the installation space of the belt conveyor becomes large and a large factory is required. Will end up. Also, if the belt conveyor fails, the tire transportation will stop,
The tire manufacturing efficiency is reduced.

Therefore, in order to solve the problem of conveyance by the belt conveyor, the connecting portion of each belt conveyor is
It is considered to provide a buffer portion that can store a predetermined number of tires by vertically conveying the tires. Figure 38
An outline of such a conventional tire conveying device is shown in FIG.

As shown in FIG. 38, between the belt conveyors 01 and 02 which horizontally convey the tires T, there is provided a rotary conveyor 03 which vertically conveys the tires and stores a predetermined number of the tires. The rotary conveyor 03 is configured by a pair of upper and lower sprockets 04, 05 being hung around so that a chain 06 can be circulated, and a plurality of pedestals 07 are attached to the chain 06.

Therefore, the tires T transported by the belt conveyor 01 are sequentially mounted on the receiving table 07 of the rotary conveyor 03 by a loader (not shown), and are circulated by the chain 06 to be vertically transported and stored in a predetermined quantity. Then, when the tire T mounted on the pedestal 07 rises and then descends and comes to a position adjacent to the belt conveyor 02, the pedestal 0
The tire T on 7 is transferred and conveyed to the belt conveyor 02 by a loader (not shown).

However, in the rotary conveyor 03 of the above-mentioned conventional tire conveying device, the pedestals 07 for mounting the tires T are attached to the chain 06 at equal intervals, and during operation, Since all the pedestals 07 move, it is necessary to carry out the loading and unloading of the tire T in synchronization. Therefore, if the tires cannot be loaded due to the timing difference between the loading and unloading of the tires,
There is a sky at 7. In this case, the empty pedestal 07 cannot be clogged, and there is a problem that the storage capacity is reduced. On the other hand, if the tires cannot be carried out due to the timing difference between when the tires are carried in and when the tires are carried out, the tires T cannot be mounted on the cradle 07, and the storage capacity also decreases here.

Further, in this rotary conveyor 03, each pedestal 07 is empty at the start of operation, and in order to convey the tire T to the belt conveyor 02, the tire T is transferred from the belt conveyor 01 to the rotary conveyor 03. However, the tire T has to be transferred onto the belt conveyor 02 after the rotary conveyor 03 is circulated, which causes a time lag. Therefore, there is a problem that the time difference between the pre-process and the post-process cannot be absorbed, and the transport efficiency and the manufacturing efficiency are not good.

The present invention solves such a problem, and an object of the present invention is to provide a vertical conveying apparatus for conveying a conveyed object with an improved conveying efficiency.
