Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a neck ring mechanism of a glass bottle forming machine.

[0002]

2. Description of the Related Art 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 form a finished mold by blowing (blowing compressed air). In this case, the parison molded in the rough mold has its mouth gripped by the mouth mold of the neck ring mechanism, and is inverted into the finished mold by the invert mechanism.

FIG. 5 shows a conventional neck ring mechanism of a glass bottle forming machine.

[0004] Reference numeral 101 denotes a rotation shaft that is rotatable in the direction of arrow A. The rotation shaft 101 is provided with a pair of cylinders 103 slidably on the shaft. A mouth holder 105 is attached to each cylinder 103, and each mouth holder 10
At the tip of 5, a half mold half 107 divided into two parts is fixed, respectively. The rotating shaft 101 has a pair of cylinders 1
An internal passage 109 is formed for supplying compressed air for driving the fuel cell 03. The internal passage 109 is provided with an electromagnetic valve 111 capable of supplying compressed air and a flow control valve 1
13 are connected in series.

When the solenoid valve 111 is switched to the position A, compressed air is supplied to the internal passage 109, and the pair of cylinders 103 open in the direction of arrow B against the spring force of the spring 115, and Is opened.

When the solenoid valve 111 is switched to the position B, the compressed air is exhausted from the internal passage 109, the pair of cylinders 103 are closed in the direction of arrow C by the spring force of the spring 115, and are fixed to the mouth holders 105. The closed mold 107 is closed.

[0007]

However, in the conventional configuration, since the pair of cylinders 103 are driven to open and close through one system of internal passage 109, the opening and closing operations of the left and right cylinders 103 vary. When the parison is lowered to the finishing mold, there is a problem that the parison tilts or rotates.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a neck ring mechanism for a glass bottle forming machine which solves the above-mentioned problems of the prior art and does not cause variation in opening and closing operations of a pair of cylinders. It is in.

[0009]

In order to achieve the above-mentioned object, the invention according to claim 1 provides a neck ring mechanism for gripping a mouth of a parison when a parison is transferred from a rough mold to a finish mold. The neck ring mechanism includes a rotating shaft, a pair of cylinders sliding on the rotating shaft, and a die holder fixed to each cylinder and holding a die that can be freely opened and closed. Driving means capable of individually controlling the driving of the cylinders is provided.

According to a second aspect of the present invention, the neck ring mechanism holds a rotating shaft, a pair of cylinders sliding on the rotating shaft, and a mouthpiece fixed to each cylinder and capable of opening and closing. A mouth-type holder, and a drive means capable of individually controlling the drive of the pair of cylinders is provided. The drive means is provided inside a two-system formed on a rotating shaft for supplying compressed air for driving the pair of cylinders. A passage is provided, and compressed air can be supplied independently to the two internal passages.

In these inventions, a driving means capable of individually controlling the driving of the pair of cylinders is provided. Therefore, by adjusting the opening / closing operation of each cylinder by the driving means, the variation in the opening / closing operation of each cylinder can be adjusted, and the parison can be lowered vertically to the finishing mold.

[0012]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a glass bottle forming machine. This 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 7, a gob deflector 8, 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
The parison P is formed by being pressed by a plunger (not shown).

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 is transferred onto a cooling dead plate 29.

Then, it is extruded from the dead plate 29, transferred onto the conveyor 31, and
It is sent to an annealing furnace not shown through 1.

FIG. 2 shows the invert mechanism 21. The invert mechanism 21 includes an air cylinder 81, and a rack 82 is provided on an output rod of the air cylinder 81. The rack 82 is engaged with a pinion 34, and the pinion 34 is fitted on the rotating shaft 33.

According to this, when the rod of the air cylinder 81 reciprocates, the pinion 34 rotates and the rotating shaft 33 rotates.
Is configured to rotate.

The rotating shaft 33 constitutes a part of the neck ring mechanism 20, as shown in FIG. As shown in FIG. 4, a pair of cylinders 35 are attached to the rotating shaft 33 so as to be slidable on the shaft. Further, a mouth holder 37 is attached to each cylinder 35, and the tip of each mouth holder 37 is divided into two by the mouth 19.
Are fixed respectively. The pinion 34 is fitted in the center of the rotating shaft 33, and the pinion 34
2 (FIG. 2) mesh with each other, and the rotating shaft 33 is rotated by the vertical movement of the rack 82.

In this embodiment, as shown in FIG. 4, a driving means 50 capable of individually controlling the driving of a pair of cylinders 35 is provided.
Is provided.

The driving means 50 has two internal passages 51 formed inside the rotating shaft 33. Each of the internal passages 51 has a solenoid valve 52 capable of supplying compressed air.
In addition, a flow control valve 53 is connected in series.

When each of the solenoid valves 52 is switched to the position A, compressed air is supplied to each of the internal passages 51, and the pair of cylinders 35 are opened in the direction of arrow B against the spring force of the spring 36. The mouth mold 19 fixed to the mouth mold holder 37 is opened.

When each of the solenoid valves 52 is switched to the position B, compressed air is exhausted from each of the internal passages 51, the pair of cylinders 35 are closed in the direction of arrow C by the spring force of the spring 36, and Mouth mold 19 fixed to 37
Is closed.

When opening and closing the pair of cylinders 35,
If the opening / closing operation of the left and right cylinders 35 varies, the parison tilts or rotates when the parison is lowered to the finishing mold.

In this embodiment, when the opening / closing operation of the pair of cylinders 35 varies, the variation is adjusted by adjusting the respective flow control valves 53.

As described above, since the driving means 50 capable of individually controlling the driving of the pair of cylinders 35 is provided, the opening / closing operation of each cylinder 35 is adjusted by the driving means 50 so that the opening / closing operation of each cylinder 35 is performed. The parison can be adjusted, and the parison can be lowered vertically to the finishing mold.

It is apparent that the driving means 50 may be another means such as a linear motor without depending on the air cylinder type.

[0027]

According to these inventions, a driving means capable of individually controlling the driving of a pair of cylinders is provided. Therefore, by adjusting the opening / closing operation of each cylinder by the driving means, the variation in the opening / closing operation of each cylinder can be adjusted, and the parison can be lowered vertically to the finishing mold.
