Latest Patents

One of Ashizawa's latest patents is a printing plate stacking device and a method for judging the authenticity of sheet member detecting states. This invention features an intermediate guide member that is attachable and removable between a head portion and a supporting frame of a stocker for printing plates. The design includes a number of intermediate guide members that set the timing for the downward movement of hooks supporting the leading end of a printing plate. The invention establishes three conditions based on lengths of non-detection times to effectively detect the printing plate and judge the authenticity of the detection. When the hooks approach the stoppers provided at the supporting bars of a reversal unit, they swing and are pulled in from above the slope to transfer the printing plate to the stoppers. Subsequently, by rotating the supporting bars and stoppers integrally around a shaft, the printing plate pivots toward a back plate, allowing the lower end of the printing plate to be transferred from the stoppers to a receiving plate without causing any damage.
