As such, when the standing angles of dishes are changed by the bending induction unit, dishes arranged to stand on the tableware transfer belt are washed and rinsed according to the rectangular area where the washing and rinsing water does not reach by adjacent dishes, and the set spraying angle of the washing rinsing water. The washing efficiency is improved because the rinsing washing water is stably sprayed to each part of the tableware without the occurrence of the dead area where the number does not reach inevitably, and the washing and rinsing water does not reach the dead area. .

However, since the support fingers constituting the tableware transport belt of the conventional tableware transport device are configured to always support the tableware upright at a predetermined angle, the tableware moves through the upward transport section and the downward transport section formed by the bending induction unit. If the tableware rotates with its own weight forward and backward, a phenomenon occurs that the tableware rotated by its own weight is separated from the support finger.

As such, when the dishes are separated from the support fingers, it is difficult to ensure continuity of operations according to washing and rinsing of the dishes, and in particular, physical damage to the dish transfer device including the dish transfer belt may be caused by the detached dishes. .
