Title:
DEVICE FOR SUPPLYING MOLTEN METAL, METHOD FOR MANUFACTURING GLASS PANEL USING SAME, AND GLASS PANEL
Document Type and Number:
WIPO Patent Application WO/2019/093326
Kind Code:
A1
Abstract:
Despite being provided with a flow rate adjustment mechanism and an opening/closing valve mechanism, the present invention makes it possible for each to operate with good precision, and processing is facilitated. A glass panel P in which a spacer 2 is provided between a pair of glass plates 1A, 1B and a gap V is formed, wherein a peripheral edge part V1 of the pair of glass plates 1A, 1B is filled with a molten peripheral sealing metal material 3, and the gap V is hermetically sealed. The present invention is provided with: a melting tank 36 for the peripheral sealing metal material 3; a flow rate adjustment mechanism 32 for the peripheral sealing metal material 3, provided with a valve body 31 whereby a gap between the valve body and a conical valve seat 30 on a bottom end part of the melting tank 36 can be freely adjusted; and an opening/closing valve mechanism 43 whereby a flow of molten metal adjusted by the flow rate adjustment mechanism 32 can be freely stopped. The melting tank 36, the flow rate adjustment mechanism 32, and the opening/closing valve mechanism 43 are each formed so as to be separately operable and are arranged in order from the top on a vertically communicated linear flow channel 34, so that a foreign substance differing from a main component of the peripheral sealing metal material 3 can mix with the main component in the peripheral sealing metal material 3.
