Embodiment
Below, with reference to the description of drawings embodiments of the present invention.
(embodiment 1-1)
Fig. 1 is the outside drawing of manufacturing installation 1 of the glass rotary body of present embodiment.
The manufacturing installation 1 of this glass rotary body comprises: the process furnace 3 as heating unit that glass block 2 is heated; The forming section 4 of molding glass piece 2; Glass block 2 after the heating is delivered to the delivery section 5 of forming section 4; The control part 6 of control device integral body.What process furnace 3 used is the common heating furnace with peristome 7, through this peristome 7 glass block 2 is sent in the stove, and the glass block 2 after this peristome 7 is the process thermoplastic is sent.This process furnace 3 can be controlled the Heating temperature of inside heating furnace and heat-up time etc. arbitrarily by control part 6.
Forming section 4 comprises: as for example first and second rollers of molded component to 11,14 and drive described first and second rollers to 11,14 as electric motor 17,18 of drive unit etc.And, in the drawings, also be provided with for example heat first roller to 11 well heater 21,21 as heating unit '.In addition, diagram has been omitted and has for example been heated second roller to 14 the well heater as heating unit.
Delivery section 5 comprises: vertical strut 9, and its upper end is supported on the device frame 8 by this way: promptly, by not shown drive unit, (arrow A-A ' direction) goes up and moves in the horizontal direction, and can turn round (arrow B-B ' direction) in horizontal plane; Cross struts 10, it is fixed on the bottom of this vertical strut 9 integratedly.By this delivery section 5, can send into glass block 2 in the process furnace 3, and will offer forming section 4 by the glass block 2 after these process furnace 3 thermoplastics.
As mentioned above, the temperature of control part 6 control process furnace 3, time etc., and to first and second rollers in the forming section 4 to 11,14 and the rotation of electric motor 17,18 etc. control, in addition, also the action of delivery section 5 etc. is controlled.
As the shape of glass block 2 before the heating, employing be for example polygon prism, cylinder, the glass block of spheroid form or grumeleuse (gob) shape roughly.And in process furnace 3, glass block 2 is heated to and is unlikely to make it to become liquid temperature and softening.This be because: that it is become is liquid if glass block 2 is heated to, and then is difficult to make glass block 2 rollings in forming section 4 and is configured as the glass rotary body of sphere etc.And, and glass block 2 is heated into liquid situation compares, the structure of process furnace 3 uses simple structure to get final product.
Particularly, the heating of glass block 2 in process furnace 3 it is desirable to be heated to that to make glass block 2 become viscosity be 10 4～10 12Pool, become the temperature before liquid.In addition, viscosity 10 4Pool is the yield point (10 of viscosity ratio glass 5Pool) state of lower slightly (soft), and viscosity 10 12Pool is a viscosity ratio glass transition point (10 13～10 15Pool) state of lower slightly (soft).This be because: therefore from for example having carried out heating condition by 3 pairs of glass block of process furnace 2, when forming section 4 is carried, the temperature of glass block 2 might reduce, and estimating this part heats.In addition, when reality is shaped, it is desirable to be shaped to the viscosity in the scope of glass transition point with yield point from glass.
In addition, the viscosity of glass is 10 4Pool, this viscosity is the value lower than the yield point of glass, but the viscosity 10～10 of the glass of this viscosity ratio molten state 3Pool is high, thereby can clearly distinguish the glass melting state.
In addition, the temperature that it is desirable to the molded component (for example, first and second rollers are to 11,14) in the forming process is lower than the Heating temperature of glass block 2.On the other hand, be higher than in the temperature of molded component under the situation of Heating temperature of glass block 2, might between glass block 2 and molded component, produce adhesion etc.And in the present embodiment, because unique point is, the glass block 2 that has been softened in cooling forms its solidified simultaneously, therefore it is desirable to make the temperature of molded component to be lower than the Heating temperature of glass block 2.And think that the temperature of in forming process glass block 2 is than glass transition point height.
More than the explanation with the shape of glass block 2, the heating condition of glass block 2 and the relevant condition of temperature of molded component, be the generic concept that is applicable to whole all embodiments described later.
As mentioned above, the heating of glass block 2 regularly, can be that glass block 2 is offered before the forming section 4, and for example also can be first roller that the glass block 2 before the heating is sandwiched forming section 4 to 11 and second roller between 14, this glass block 2 is heated 11,14 with first and second rollers.In addition, about first and second rollers to 11,14, both can pass through well heater 21,21 ' etc. separately pair of rollers perhaps also can be with glass block 2 heating to heating, also can be, and heated rollers is not right only to glass block 2 heating.In addition, in Fig. 1,, second roller is expressed as with respect to first roller 11 states of backing out 14 in order to hold content easily.
