る。B. Prior art Conventionally, a predetermined number of molds are arranged at equal intervals around a rotary disk that rotates intermittently, and gobs (molten glass lumps) are supplied from a gob feeder while the rotary disk is stopped, and one plunger is A press-molding method for glass products is known.

いを要する。 As mentioned above, when a predetermined amount of gobs are supplied from the gob feeder G to the mold M in the first station, the rotary disk R is arranged at an interval corresponding to one mold M.
It is rotated by 1P and then stopped, thereby
The mold M that was at the first station is moved to the second station, and the mold M that was at the n-th station is moved to the first station. A metered amount of gob is supplied. Subsequently, the rotary disk R is rotated by an arrangement interval 3P corresponding to the three molds M and then stopped, whereby the two gobs that have been supplied to the first station and the second station are separated. The molds M and M are the fourth station and the fifth station.
The two plungers P1 and P2 of the press-forming mechanism installed in this station reach the station.
Press molding is performed on two pieces at the same time. That is, in the present invention, the gob is supplied to one mold M each time the rotary disk R stops, and the press molding operation of the plungers P 1 and P 2 is performed every time the rotary disk R stops. During the stop operation, two molds M are simultaneously processed once every two molds. After that, the rotary disk R repeats intermittent rotation for 1P and 3P, and the press-formed glass product is cooled down at the cooling station, and after being removed from the mold M of the annular mold 19, it reaches the take-out station. The product is removed from the mold M.
In addition, in the above-mentioned first operation explanation, the molds M and M in the second and third stations already contain press-molded products, and in the case of this embodiment, gobs are not supplied. The rotary plate R requires about one and a half rotations from the time the product is removed until the product is taken out.

によつて経験的に求められるものである。 First, the stop time of the intermittent rotation of 1P and 3P of the rotary disk R is set to the time required to feed the gob into the mold M (short time) after rotating by 1P, and , the stop time after rotating by 3P is set to the required time (long time) required for press molding of the gob by plungers P1 and P2.
The reason why the stop time of the intermittent rotation of the rotary disk R is set to be long or short is as follows. That is, the gobs of molten glass in the molds M, M are connected to the plunger P.
1. When pressure molding is performed by P2, the glass temperature of the glass molded product immediately after molding is still in a high temperature state where it may soften and fluctuate, so when this has not yet hardened to a certain extent, the plungers P1 and P2 are removed from the mold. M,M
When the glass is pulled out of the mold, the parts of the glass that are in contact with the plungers P1 and P2 are still in the adhesive temperature range, so they may stick to the plungers P1 and P2 or deform within the molds M and M, reducing molding accuracy. make worse. Therefore, the stop time after the rotary disk R rotates by 3P is a sufficiently long time until the temperature of the glass at the contact boundary where it is in contact with the plungers P1 and P2 falls below the adhesive temperature, so-called plunger P1. , P2 is set to the time required for press molding of glass products. Note that this time is determined empirically depending on the shape and dimensions (size, wall thickness, etc.), material, etc. of the glass product.

著しく向上させたものである。 On the other hand, the stop time after the rotary disk R rotates by 1P is set to a short enough time to feed a predetermined amount of gobs from the gob feeder G into the mold M.
This reduces the time required for the production cycle compared to the conventional method in which the stop time of intermittent rotation is constant, and in conjunction with the two-piece simultaneous molding method, significantly improves productivity.

る。 To summarize the above operation description, after the rotary disk R rotates by 3P and stops, pressure forming is performed by the plungers P1 and P2, and just before the end of this press forming, the mold M located directly below the gob feeder G A predetermined amount of gob is fed into the container. When the long stop time required for this press forming has passed, the rotary plate R
rotates by 1P and stops, and then a predetermined amount of gobs are fed into the mold M that is located directly below the gob feeder G. The stop time at this time is a short stop time required for supplying the gob, and after this time, the rotary disk R rotates by 3P, and the two plungers P
1 and P2, two pieces are press-molded simultaneously, and the same operation is repeated thereafter.

This is an example in which the arrangement interval is set to 1P for 1 piece and 3P for 3 pieces, but it is not limited to this, and 1P and 2P
It can be implemented in various ways, such as a combination setting of 2P and 1P, or a combination setting of 2P and 1P. Any combination of alternating repetition and alternating length and shortness of the stop time of the intermittent rotation of the rotary disk R is included in the first aspect of the present invention, for example, the amount of intermittent rotation and the stop time. The combination may be either [short and short, long and long] or [long and short, short and long]; in the case of Figure 1, 1P (short) and short , 3P (long) and a long time.For example, if this is a combination of 2P (long) and a short time, or 1P (short) and a long time, the press molding position is the second station in Figure 1. In addition, in the case of a combination of 1P (short) and short time and 2P (long) and long time, the press molding positions will be the third and fourth stations in FIG. In this way, when the amount of intermittent rotation of the rotary plate R is repeated alternately between long and short periods, only one gob feeder G may be provided, and two press forming mechanisms may be provided. The installation position is expressed as n 1 P for the long intermittent rotation amount and n 2 P for the short intermittent rotation amount, in the case of a combination of [long and short, short and long], relative to the installation station of the gob feeder G, The installation station for the first press-forming mechanism is installed at a station that has advanced by n 2 P in the rotational direction of the rotary plate R, and the installation station for the second press-forming mechanism is installed at a station that has advanced further by n 1 P from that point. It can be installed at the station at the location. Also, on the contrary, [short and short,
In the case of a combination of length and length], the first press-forming mechanism is located at a station n 1 P ahead of the gob feeder G, and the second press-forming mechanism is located at a position further n 2 P ahead of the station. It will become a station for
