Reference numeral 6 is a gas burner for heating the glass mouth G forming portion of the glassware G placed on the glassware placing table 3.

The glass container mounting table 3 is configured to hold and fix a glass container mounted on a vacuum hole formed in the table body 3a by vacuum suction, and the table body 3a is an ascending / descending table made up of an air cylinder device. It can be moved up and down by the actuator 3b and is controlled by a sequence controller (not shown).

The mouth forming mechanism 4 includes a fulcrum arm 4b extending downward from the bottom of the fixed frame 4a and a fulcrum arm 4b.
Operation arm 4c rotatable about the lower end of the fulcrum (O)
An operating arm rotation actuator 4d including an air cylinder device that drives the operating arm 4c;
The rotation restricting plate 4e for restricting the operating angle of c is adjustable, and the tip of the operating arm 4c is inserted into the long hole 4f of the rotation restricting plate 4e bolted to the fixed frame 4a. By adjusting the position of the motion restricting plate 4e in the vertical direction, the rotation end angle of the operating arm 4c, which is operated counterclockwise by the operating arm rotating actuator 4d, is set to, for example, horizontal (FIG. 3) or 20 degrees (FIG. 4) and regulate the crow mouth as shown in FIG. 8 to the operating arm 4c.
So that it can be molded.

Further, the operating arm rotation actuator 4d
Is controlled by the sequence controller described above.

The operating arm rotation actuator is
Although an air cylinder is used, a rotating cam can also be used.

The elevator 5 comprises a bracket 5a fixed to the column 2 and a lift actuator 5b consisting of an air cylinder fixed to it. An actuating rod 5c of the lift actuator 5b is fixed to a fixed frame 4a of the mouth forming mechanism 4.
The vertical position is adjusted so that the operating arm fulcrum position of the fulcrum arm 4b of the mouth forming mechanism 4 can be located below the rim of the glassware G at the lower end of the operating rod 5c.

The elevating actuator 5b is driven and controlled by the above sequence controller.

Next, an elevating actuator 5b and an operating arm rotating actuator 4 by a sequence controller.
d, the operation of the platform elevating actuator 3b will be described.

In the standby state before the operation is started, the mouth forming mechanism 4 is used.
Is in the upper position (the fulcrum of the actuating arm is not inserted into the mouth of the glassware G), so that the actuating arm of the mouthpiece forming mechanism 4 is not in contact with the mouth of the glassware. It is in the position where it is flipped up, and the glass body mounting table 3 has the table body 3a at the upper end position.

When the glass instrument presence / absence sensor 7 detects that the glass instrument G is placed on the table body 3a of the glass instrument placement table 3 in the above-mentioned standby position, the flame of the gas burner 6 is strengthened to start the work. Heat the mouthpiece forming part of the glassware. Then, the elevating actuator 5b is driven so as to descend the mouthpiece forming mechanism 4 toward the glass device G. When the mouth forming mechanism 4 is lowered to a predetermined operating position as shown in FIG. 2, the operation arm rotation actuator 4d is driven, and the operation arm 4c is moved to the mouth forming portion of the glassware G around the fulcrum (O). The crow mouth is formed by inclining toward the outside and inclining the softened glass at the crow mouth forming portion to the outside.

Here, when the angle of the crow mouth to be mouth-formed is not so tight as shown in FIG. 8 (a), the working arm 4c of the operating arm 4c is shown in FIG. Even if the rotation fulcrum (O) is fixed with respect to the glass device G, the crow's mouth is finished fine, but (b), (c) of FIG.
When the angle of the crow's mouth is tight as shown in (d), for example, when the horizontal (90 degree) crow's mouth is formed by mouth as shown in (a) of FIG. 5, the rotation fulcrum (O )
When fixed to the glassware G, as shown in FIG. 5B, there was a problem that the glass pushed by the operating arm 4c was accumulated at the root portion of the crow's mouth and the finish became dirty.

Therefore, in the present embodiment, when the operation of the operation arm 4c is started, the table elevating actuator 4b is driven so as to lower the table body 3a of the glass table mounting table 3, and as shown in FIG. While the fulcrum (O) of the operating arm 4c is raised with respect to the crow mouth forming portion, the mouth forming is performed by the operating arm 4c. That is, at the time of forming the crow's mouth, the glass at the crow's mouth forming portion is inclined while being pushed outward by the operating arm, and the glass is not crushed right below as in (b) of FIG. It is formed into a beautifully shaped crow's mouth.

Since the mouth-forming operation of the operating arm 4c may be performed while raising the rotation fulcrum (O) of the operating arm 4c with respect to the glass mouth crow forming portion, the base body of the glassware mounting table 3 is formed. The same effect can be obtained by performing the mouth-forming operation while raising the operating arm 4c without lowering 3a.

When the molding operation of the crow mouth while lowering the table body 3a is completed in this way, the operating arm 4c and the table body 3a return to their original positions, and the mouth-forming machine 4 is also moved to the original position by the elevator 5. Then, the process waits until the next mouth forming operation starts.

In the above-described embodiment, the case of forming a spout for water or the like at the mouth of a glassware is taken as an example, but the invention can also be applied to a case where a plurality of mouthpieces are formed around the mouth. However, in this case, a plurality of operating arms may be provided.
