Detailed Description of the Invention [Industrial applications]

The present invention relates to a conveyor device such as a belt conveyor.

BACKGROUND OF THE INVENTION

Today, when clothes, such as shirts or sweaters, are put out at a cleaning collection / delivery store, they are marked with a predetermined mark, which is then sent to a cleaning plant, and after cleaning work is performed, the cleaning work is performed. Clothes that have already been sorted are sorted into each collection and delivery store,
Then, a system is implemented in which the goods are delivered to each collection / delivery store, and thereafter, each home goes to the collection / delivery shop to receive the goods. In the implementation of such a system, as a task that each cleaning maker suffers, although the cleaning task itself also suffers, there is a task of sorting the cleaned clothes at each collection / delivery store after cleaning. . That is, even in the cleaning industry today, the scale has been increased, and dozens of collection and delivery stores correspond to one cleaning factory. Therefore, it is possible to deliver the cleaned and efficiently cleaned items to each collection and delivery store. It has to be done, but it can be said that a desirable device capable of performing such work has not been developed. It should be noted that such a sorting device is not completely absent, but the ones provided so far are large in size, and the sorting operation itself is not efficient. Therefore, the present inventor proposed a technique (Japanese Patent Application No. 62-278267) that invented a sorting device as shown in FIGS. 4 to 8 and drastically solved the above problems. In the drawings, 1A, 1B, 1C, ..., 1N are belt conveyor bodies, and these belt conveyor bodies 1A, 1B, 1C, ..., 1N are roughly air cylinder devices, one-way clutches and belts. In addition, the reciprocating motion of the cylinder rod of the air cylinder device is converted into a one-way rotational motion by the one-way clutch, whereby the belt makes an elliptical motion. Since each of the belt conveyor bodies 1A, 1B, 1C, ..., 1N is provided with an air cylinder device, for example, even if the belt of the first belt conveyor body 1A is operating,
