Title:
METHOD AND DEVICE FOR TIME-DIVISION CONTROL OF DRYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/066590
Kind Code:
A1
Abstract:
Provided is a time-division control device for which the amount of electricity supplied for at least one hot plate is sufficient and an increase in the factory power-receiving equipment is not required, even if the number of drying devices increases; or, which is capable of reducing the maximum flowing current value to the current value for one heater for an existing drying device equipped with multiple heaters when said multiple heaters are heated in parallel.
This time-division control device (A) supplies power by sequentially switching the supply of power to the heaters (H1)-(Hn) for multiple hot plates (HP1)-(HPn), which are connected in parallel to an alternating current main power supply (1) and which respectively heat and dry, at a prescribed temperature, multiple processing bodies (2) on which an application liquid has been applied. The time-division control device is characterized in that it comprises: the existing alternating current main power supply (1), which supplies alternating current to each of the aforementioned multiple heaters (H1)-(Hn); parallel connection lines (n1) - (nn), which branch from the alternating current main power supply (1) and respectively supply power to the heaters (H1)-(Hn), and temperature measurement instruments (THS1) - (THSn) for the heaters (H1) - (Hn) and the hot plates (HP1) - (HPn); and a power supply control circuit (K), which, with the zero cross point of the alternating current to each of the heaters (H1) - (Hn) as the power supply switching point, and until each of the hot plates (H1) - (Hn) reaches the set temperature, uses a temperature signal from the aforementioned temperature measurement instruments (THS1) - (THSn) to switch the supply of power to the next selected heater after a rest period of a half-cycle or an integer multiple thereof from said power supply switching point, with the number of hot plates being the same as or less than the number of existing hot plates when the number of hot plates is being increased and the number of hot plates being one less than the number of existing hot plates when the number of hot plates is not being increased.
