So, side cooling unit 20 be configured in the melten glass that is used to make melten glass to flow out flow out pipe 7 end 7b near.As long as side cooling unit 20 can cool off melten glass and flow out pipe 7 and mobile melten glass therein, flow out at melten glass near the side of pipe 7, needn't limit the position of configuration side cooling unit 20.As the ideal form, in order to cool off effusive melten glass fully, side cooling unit 20 be configured in melten glass flow out pipe 7 end 7b near.
In order to cool off the end 7b that melten glass flows out pipe 7 respectively, the inside in the end around parts 23,24 has cooling unit around parts 23,24 in the end.More concrete is exactly, and the end is hollow around the inside of parts 23,24.Side cooling unit 20 makes melten glass flow out the end 7b cooling of pipe 7 by making portion's round-robin method of cooling within it such as air, oil, water via the melten glass between end 7b and the medial surface 28.Though method of cooling can be to make round-robin such as air, oil, water well-known methods in the past,, preferably make water in internal recycling from low cost and handle angle easily.
In addition, special qualification is not done around shape, the size of parts 23,24 in the end.The bore that can flow out pipe 7 according to the size and the melten glass of the melting plant 6 of accommodating melten glass carries out suitable change.
(melten glass receiving-member)
Glass flow-out control device 10 has the acceptance division mobile unit 60 that melten glass acceptance division 40 is relatively moved with respect to side cooling unit 20.
Melten glass acceptance division 40 has a pair of rectangle melten glass receiving- member 41,42 of the face that jointly forms melten glass acceptance division 40 upsides and keeps a pair of melten glass to accept a pair of groove shape (channel) track 45,46 of parts 41,42 in transportable mode.Thereby melten glass acceptance division 40 is to cool off and flow out pipe 7 from melten glass and cut off the parts that melten glass that viscosity uprise receives by side cooling unit 20.
Melten glass acceptance division 40 is configured in melten glass and flows out on the extending direction of end 7b downside of pipe 7.In addition, melten glass acceptance division 40 also can be arranged on from end 7b and separate on the position of predetermined gap to downside.In the present embodiment, this gap is 10mm.
Glass flow-out control device 10 possesses acceptance division mobile unit 60, and this acceptance division mobile unit makes a pair of melten glass receiving- member 41,42 mutual butts, so that melten glass receiving- member 41,42 forms the face of melten glass acceptance division 40 upsides.Acceptance division mobile unit 60 possesses butt thruster (pusher) 61,62.Can enumerate cylinder and hydro-cylinder as butt thruster 61,62.So melten glass receiving- member 41 and 42 is configured in respectively on track 45 and 46,, move along pair of tracks 45 and 46 so that it is along with the action of butt thruster 61 and 62.

Melten glass acceptance division 40 also can be to form as one with a melten glass receiving-member, and receives melten glass.
(anti-drop device)
(control method of glass flow-out control device)
Above glass flow-out control device 10 flows out melten glass as following.
In the time of among mould carrying device 8 is configured in mould conveyance platform 8a framework 2, glass flow-out control device 10 makes drive-motor (not shown) action, makes arm 3 also have glass to flow out control strip 10a, 10b and moves to position at a distance of farthest.Thus,, do not dispose glass flow-out control device 10, flow directly into mould so flow out pipe 7 effusive melten glass from melten glass because melten glass flows out between pipe 7 and the mould conveyance platform 8a.
At this moment, glass flow-out control device 10 makes 61,62 actions of butt thruster, so that see by the end around parts 23,24 hiding a pair of melten glass receiving- members 41,42 from above.
Glass flow-out control device 10 stops the outflow of melten glass as following.
By Fig. 6 to Figure 11 no, glass flow-out control device 10 at first just drive-motor (not shown) action is in contact with one another so that a pair of glass flows out control strip 10a, 10b.Thus, a pair of glass flow out control strip 10a, 10b with specified gap be positioned at melten glass flow out pipe 7 end 7b near.
In addition, as shown in Figure 10, the front end of the insertion pin parts 81 of quadrangular shape is inserted in the patchhole 82 by logical.Thus, insert pin parts 81 and push the locking pin support unit 87 that is configured in the patchhole 82, be inserted in the hole 89 that is formed on the front end that inserts pin parts 81 with the locking pin 88 of the top butt of locking pin support unit 87.Thus, a pair of glass outflow control strip 10a, the 10b of an end butt can not be separated from each other.
As Fig. 9 and shown in Figure 11, partly solidified even melten glass flows out in the specified gap between pipe 7 and the melten glass receiving- member 41,42 at melten glass, might not have solidified partly to flow down yet and exert pressure in this gap.Like that, making pair of end portions center on parts 23,24 by anti-drop device 80 does not separate.In addition, anti-drop device 80 prevents that also melten glass from spilling from the gap of abutment portion.
Next glass flow-out control device 10 makes 20 actions of side cooling unit, cools off the sidepiece refrigerating work procedure that melten glass flows out the sidepiece 7a of pipe 7.Thus, the sidepiece 7a that melten glass flows out pipe 7 is cooled, and the viscosity of mobile melten glass uprises in this section.But, see by the end on the position that parts 23,24 are hidden because a pair of melten glass receiving- member 41,42 is configured in from above, so the melten glass that viscosity uprises continues to flow out from melten glass outflow pipe 7.
Next glass flow-out control device 10 makes butt thruster 61,62 action, and the melten glass that the distance that the end 7b that flows out pipe 7 from melten glass separates regulation receives melten glass receives operation.Thus, melten glass receiving- member 41,42 clogs the medial surface 28 that the end forms around parts 23,24.Like this, be cooled and melten glass that viscosity uprises is accepted prevention by the melten glass acceptance division, solidify by naturally cooling again.The glass that has solidified flows out the embolism that the outflow of the melten glass of pipe 7 stops and working as making from melten glass.
In other words, melten glass is after the melten glass pipe that has been cooled by side 7a flows out, and melten glass receiving- member 41,42 opposite flank cooling units 20 move and catch melten glass.Because melten glass is melted glass receiving- member 41,42 and is cooled to a certain extent before catching, viscosity uprises, so when being caught by melten glass receiving- member 41,42, solidify easily.
In addition, glass flow-out control device 10 makes the action of acceptance division cooling unit, makes 41,42 coolings of melten glass receiving-member forcibly.
In addition, a pair of melten glass receiving- member 41,42 moves opposite to each other in the mobile mode of cutting off melten glass.In other words, a pair of melten glass receiving-member is according to the mode of the face of common formation melten glass acceptance division upside, and a side and the opposing party move mutually in opposite directions, carry out butt.Thus, by making melten glass receiving- member 41,42 mutual butts, the melten glass receiving-member can cut off flowing of melten glass deftly under the mobile mode of disturbance melten glass hardly.
Since gapped between melten glass outflow pipe 7 and melten glass receiving- member 41,42, so melten glass is caught by melten glass receiving- member 41,42 and is solidified, and plays the effect of the embolism that takes this predetermined gap.
Because cooling unit 20 quilts in side are according to making the end center on the discontiguous mode of end 7b of parts 23,24 and melten glass outflow pipe 7, and be configured according to the mode of surrounding the end 7b of melten glass outflow pipe 7 with the interval that separates regulation, so the fluid that flows out the effusive melten glass of end 7b of pipe 7 from melten glass is melted after glass receiving- member 41,42 catches, enters this gap and solidify.So melten glass self becomes the embolism that stops up this gap, melten glass stops.
