Title:
カローゼルリールおよびカローゼルリールユニット
Document Type and Number:
Japanese Patent JP7192472
Kind Code:
B2
Abstract:
To provide a carousel reel which reliably performs changeover of an oil feed pump to be operated against restriction for one power supply system due to intervention of a slip ring without use of a limit switch and enables a safe operation of a lubrication oil feed system, and a carousel reel unit.SOLUTION: When a winding position of a first drum 41 or a second drum 42 is detected at an operation pump designation processing part 85 of a carousel reel unit 8, a proximity switch 87 or 88 is switched on, and a reversible type electromagnetic contactor 86 is operated in linkage therewith. For example, by switching-on of the proximate switch 87, a positive phase contactor MC in the carousel reel unit 8 is switched on. Thus, positive power source flows to a power supply line through a current relay 86 and is supplied to an output part 83. At the output part 83, only a reverse phase relay RPR1 of reverse relays RPR1, RPR2 is switched on, therefore only an oil feed pump 1 can be electrically conducted and driven.SELECTED DRAWING: Figure 4
