Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass bottle forming machine, and more particularly to a glass bottle forming machine having a cooling air partition plate between a finishing die and a dead plate box. About. [0002] For example, when a glass bottle is formed by a press-and-blow method, it is common to form a parison in a rough mold and then to form a final mold by blowing (blowing compressed air). . In this case, the glass bottle formed by the finishing die is transferred to the dead plate box side via a take-out mechanism, but the cooling air of the finishing die is supplied between the finishing die and the dead plate box. A partition plate is provided so as not to flow into the dead plate box side. [0003] However, in the conventional configuration, when the glass bottle is transferred to the dead plate box side by the take-out mechanism, the partition plate is more moved than the path drawn by the bottom of the glass bottle. Must be located below. [0004] Therefore, since the position of the partition plate is too low, the cooling air in the finishing mold passes above the partition plate and flows into the dead plate box side, and the cooling air is transferred to the dead plate box side. There is a problem in that the glass bottle in the heated red-softened state suffers from defects such as dents in the glass bottle. In order to solve this problem, conventionally, partition plates having different heights are replaced according to the bottle length of the manufactured glass bottle, but the type of the manufactured glass bottle is frequently changed. In this case, this replacement work becomes extremely difficult. Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, and to prevent cooling air from flowing from the finishing die to the dead plate box side without replacing partition plates having different heights. An object of the present invention is to provide a glass bottle forming machine. [0007] In order to achieve the above object, according to the first aspect of the present invention, the finish type cooling air is stopped.
The finishing mold is opened and molded with this finishing mold.
Glass bottle is dead-pulled by take-out mechanism
Transferred to the rate box side, the next parison finishes as above
The finishing mold is closed and the finish is closed.
Glass bottle forming machine that starts supplying cooling air to the lifting mold
In the finish mold and the dead plate box
A partition plate is provided between the
When the cooling air is stopped and this finishing mold is opened,
Glass plate with dead plate box
When transferring to the box side, draw the bottom of this glass bottle
Gala that is lowered below the trajectory and formed by the finishing mold
Bottle with take-out mechanism, dead plate
If it is transferred to the box side, it will rise and
Cooling air transferred to the dead plate box
In such a manner as not to hit the glass bottle in the oxidized state . According to the present invention, since the partition plate rises during the normal bottle-making operation, the amount of cooling air flowing from the finishing die to the dead plate box side is suppressed, and
When the glass bottle is transferred to the dead plate box side by the take-out mechanism, the partition plate descends below the locus drawn by the bottle bottom of the glass bottle. And do not interfere. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a glass bottle forming machine. The glass bottle forming machine is supplied from a gob supply device 1 and guides a gob (glass lump) G cut by a shear 3 downward, an upper funnel 5, a gob deflector 7, a lower funnel 9, a scoop 11, a trolley 13, A deflector 15 and the like are provided. A rough mold 17 is arranged below the deflector 15, and the gob G guided to the rough mold 17 is
Pressed by a plunger, a parison P is formed. The parison P formed by the rough mold 17 is
The mouth is gripped by the mouth mold 19, and the mouth 19 is rotated clockwise in the figure by the invert mechanism 21 to be inverted into the finishing mold 23. In the finishing die 23, a glass bottle 25 is formed by blow molding, and the glass bottle 25 is rocked and conveyed via a take-out mechanism 27, and the dead plate box 2 for cooling is formed.
9 is transferred. Then, it is extruded from the dead plate box 29 and transferred onto the conveyor 31.
It is sent out to a lehr (not shown) through this conveyor 31. FIG. 2 shows the take-out mechanism 27. This take-out mechanism 27 is about 180
An arm 33 is provided which is rotatable by degrees. A tongue 35 is attached to the arm 33 so that a plurality of glass bottles 25 can be grasped at the same time. The take-out mechanism 27 is configured to hold the mouth 25a of the glass bottle 25 formed by the finishing mold 23 with the tongue 35 and transfer the glass bottle 25 onto the dead plate box 29. It is performed by a swing type. In this case, the bottom 25b of the glass bottle 25
Trace A draws a semicircular arc. FIG. 3 is a plan view showing the finishing die 23 and the dead plate box 29, and FIG. 4 is a side view of the same. When the glass bottle 25 is taken out from the finishing mold 23, as shown in FIG. 3, the finishing mold 23 is opened in half. According to this embodiment, as shown in FIG. 4, a partition plate 37 is provided between the finishing die 23 and the dead plate box 29, and the partition plate 37 is provided at the tip of a cylinder rod 39a of an air cylinder 39. It is connected to. The partition plate 37 is raised to a position shown by a dotted line during a normal bottle-making operation (to be described later), and when the glass bottle 25 is transferred onto the dead plate box 29 by the take-out mechanism 27, the glass bottle is moved. 25 bottle bottoms 2
It is lowered to the position shown by the solid line so as to be located below the locus A drawn by 5b. FIG. 5 is a flowchart. According to this flowchart, when the glass bottle 25 is transferred onto the dead plate box 29 via the take-out mechanism 27, first, the cooling of the finishing mold 23 is stopped (S1), and the finishing mold 23 is opened (S2). , Partition plate 37
Is lowered (S3). Next, the arm 33 is rotated, and the tongue 3 is moved.
5 moves onto the finishing die 23 (S4). Then, the mouth 25a of the glass bottle 25 is gripped by the tongue 35 (S
5), the arm 33 is rotated, and the movement on the dead plate box 29 is started (S6). During this time, the partition plate 37 remains down. Next, the partition plate 37 is raised (S7), and the next parison P is inverted into the finishing mold 23 (S7).
8). Then, the finishing die 23 is closed (S9), and the cooling of the finishing die 23 is started (S10). This finishing mold 2
While the cooling of No. 3 is being performed, the partition plate 37 remains up. Therefore, since the cooling air in the finishing mold 23 is blocked by the partition plate 37, the cooling air does not flow into the dead plate box 29 side, and the cooling air is transferred to the dead plate box 29 in a red softening state. The glass bottle 25 is not hit, and the occurrence of defects such as a dent in the body of the glass bottle 25 is suppressed. Moreover, when the take-out mechanism 27 transfers the glass bottle 25 onto the dead plate box 29, the partition plate 37 descends below the locus A drawn by the bottle bottom 25b of the glass bottle 25. Does not interfere with the bottle bottom 25a of the glass bottle 25 to be transferred. Although the present invention has been described based on one embodiment, the present invention is not limited to the above embodiment. For example, the partition plate 37 is not limited to being moved up and down by the air cylinder 39, but may be moved up and down by other means. The flowchart shown in FIG. 5 is an example, and the present invention is not limited to this. It is only necessary to lower the partition plate 37 at a predetermined timing. According to the present invention, since the partition plate rises during a normal bottle-making operation, the amount of cooling air flowing from the finishing die to the dead plate box side is suppressed, and therefore, the cooling air Does not hit the glass bottle in the red softened state transferred to the dead plate box side, and the occurrence of defects such as dents in the body of the glass bottle is suppressed.
