Transport amount detecting means for detecting that the transport amount has increased beyond the set transport amount; and, based on a detection signal of the transport amount detecting means, when the detected transport amount is greater than the set transport amount, the transport amount is greater than the transport supply means. On transport The conveyance drive system on the side and drive stop, and, when the amount detected transport has returned to the set carry amount lies in providing a control means for driving the conveyance drive system for conveying upstream side than the conveyance supply means. According to the above feature configuration,
When the processing amount of the object to be cleaned in the cleaning processing unit increases and the transport amount per unit time in the transport supply unit exceeds the set transport amount, the transport supply is performed while the drive of the transport supply unit is maintained. Since the drive of the transport drive system on the more transport side than the means is stopped, it is possible to suppress the movement of the object to be cleaned, the overlap of which is canceled by the overlap releasing means, being hindered by the subsequent object to be cleaned. Further, when the transport amount per unit time in the transport supply unit returns to within the set transport amount by the drive stop of the transport drive system on the more transport side than the transport supply unit, based on the detection signal of the transport amount detection unit.

Since the sheet is sent out, an abnormal situation of the transport supply unit can be indirectly detected by the transport amount detection unit. However, the transport drive system on the lower side of the transport supply unit with the transport amount detection unit alone is used. Is only stopped, so that it is not useful for solving an abnormal situation occurring in the transport supply means.
Therefore, in the present invention, the transport supply means and the transport drive system on the more upstream side of the transport are stopped based on the detection signal of the transport supply system abnormality detection sensor. By directly inspecting and repairing the transporting / supplying means, it is possible to quickly return to the expected normal operating state.

According to the characteristic configuration, when the cleaning processing speed by the cleaning processing unit is abnormally reduced or an operation abnormality such as an operation stop occurs, the cleaning is performed based on a detection signal of a cleaning system abnormality detection sensor. Since the drive of the processing means and the transport drive system on the more transport side is stopped, inspection and repair of the stopped cleaning processing means may cause the cleaning to be performed on the upper transport side due to the abnormal operation of the cleaning processing means. While minimizing the spread of clogging phenomena,
It is possible to quickly return to the intended normal operating state.

A feature of the cleaning apparatus according to a fifth aspect of the present invention resides in that the transport / supply means is constituted by an endless rotating belt-like body having a plurality of drain holes interlocked with an electric motor. . According to the above configuration, when the object to be cleaned, which has been subjected to the cleaning processing by the cleaning processing unit, is transported and supplied to the cleaning liquid removing unit, a part of the cleaning liquid attached to the object to be cleaned is endlessly rotated.
