In the above description, three main star wheels are attached to the main star axle, but the number may be reduced or increased as desired. Similarly, the leading star axle and the trailing star axle are each equipped with two leading star wheels and two trailing star wheels, but the numbers may be reduced or increased as desired. Good too.

It will also be clear that any suitable belt means, such as a belt-like belt, may be used in place of the round belt. The belt means may be stretched between at least the leading star axle and the trailing star axle.

In addition, the main star axle, leading star axle, and trailing star axle supply screw bodies are connected via a gear train to the rotating shaft of the driven wheel of the trailing belt conveyor. Similarly, the rotating shaft of the driving wheel of the leading belt conveyor is connected to the rotating shaft of the driven wheel of the trailing belt conveyor via a gear train.

Furthermore, the number of concave portions of the main star wheel is 15, and the number of concave portions of the leading star wheel and the number of concave portions of the trailing star wheel are 6, but these numbers may be changed as desired. Good too. That is, as long as the intervals between the recesses of the main star wheel, the intervals between the recesses of the leading bolt, and the intervals of the recesses of the trailing star wheel are matched during operation, the number of recesses may be selected as appropriate.

As is clear from the above, the object transfer device of the present invention has a transfer mechanism disposed between the leading belt conveyor that transports the object from the leading station and the trailing belt conveyor that transports the object to the trailing station. The direction of extension of the trailing belt conveyor can be made to intersect with the direction of extension of the following belt conveyor. In the present invention, the transfer mechanism takes the object outward from the extending direction of the leading belt conveyor and then supplies it to the trailing belt conveyor, so that the transfer distance in the transfer mechanism can be expanded, and as a result, the object can be transported in the transfer mechanism. It is extremely useful to be able to carry out additional processing such as labeling, etc., and also to carry out abnormality inspections of objects, such as damage inspection.

Furthermore, in the object transfer device of the present invention, since the object supply screw body is disposed at the entrance of the transfer mechanism, even if the object transfer speed by the preceding belt conveyor increases, the objects are sequentially transferred to the preceding star wheel and the main star wheel. can be reliably supplied. In addition, since a detection means is arranged at the inlet of the supply screw, it is possible to quickly respond if the object is not being fed properly to the supply screw.

Incidentally, the supply screw body and the guide members facing the supply screw body via the preceding belt conveyor may be arranged on both sides of the preceding belt conveyor, so that the structure may be opposite to that described above.

Further, in the above case, other detection means may be used as the detection means.
