Description

[Detailed Description of the Invention] The present invention relates to an improvement of a neck ring (mouth forming mold) drive device for a glass forming plate.

In an IS machine known as a glass bottle molding plate, the mouth of a parison molded with a set mold is supported by a neck ring and rotated 180° around a horizontal axis.
A neck ring drive is used to transport the parison to the finishing mold and feed the parison into the finishing mold as the finishing mold closes around it.

This device has a reversing function for transferring the parison and an opening/closing function for opening the parison.

By the way, since the outer diameter of the opening of the parison varies depending on the type of bottle, a means for adjusting the opening width of the neck ring drive device is also required.

In conventional neck ring drive devices, in order to adjust the stroke of the cylinder equipped with the means for attaching the neck ring arm, male threads are cut on both ends of the horizontal shaft, and a stop ring with a female thread cut on the inner peripheral surface is attached here. Rather than installing the neck ring and tightening the set bolt at the appropriate position, a structure has been adopted in which the opening width of the neck ring is adjusted.

However, such a structure has the drawback that it takes time to adjust when changing the product type, and it does not match the recent trend of completing the change of product types in a very short time.

This proposal was made to solve the above-mentioned drawbacks of the prior art.A cylinder equipped with neck ring arm attachment means is attached by splines to both sides of a horizontal shaft equipped with a reversing gear in the center. A contact surface is formed on a part of the outer surface of the cylinder head fixed to the outside of the cylinder, and a cylinder opening position setting ring with a stepped inner surface is attached to the cap fixed to both ends of the horizontal shaft as a clutch means. It is characterized by being attached through the.

The present invention will be explained in more detail below with reference to illustrated embodiments.

In the figure, 1 is a horizontal shaft supported horizontally by a bearing 2.
A gear 3 is fixed to the central part.

The gear 3 meshes with a rack 4 that moves in the vertical direction.
As the rack 4 moves, the horizontal axis 1 is reversed by 180 degrees in the forward and reverse directions.

Cylinders 5 are attached to both sides of the horizontal shaft 1 via splines 6.

An example of the cylinder 5 includes a neck ring arm attachment means 7.
A neck ring (not shown) moves the parison and opens the parison according to the rotation and sliding of the cylinder 5.

Sliding of the cylinder 5 is achieved by supplying compressed air from an air hole 8 provided inside the horizontal shaft 1, and by moving the piston 9 outward against a spring 10.

A cylinder head 11 is fixed to the outside of this cylinder 5 with bolts 12, and 120
Three contact surfaces 13 are formed at intervals of .degree.

On the other hand, a cap 14 is fixed to both ends of the horizontal shaft 1, and a setting ring 16 having an inner surface 15 formed in a stepped shape is attached to the outer periphery of the cap 14 via a clutch means 17.

Therefore, when the most protruding inner surface 15 is set at an angle facing the contact surface 13 of the cylinder head 11 as shown in FIG. 1, the opening width of the neck ring is, for example, 16771771
If the next inner surface 15 is made to face the contact surface 13, the opening width can be set to 18 mm, and the opening width can be set to 22 rMt in the same manner.

Furthermore, this setting can be performed extremely easily since the setting ring 15 is attached to the cap 14 via a clutch means.

It should be noted that since all the parts shown in FIG. 1 are rotated by the rack 4 together with the horizontal axis 1, the setting of the opening width is maintained even when the apparatus is reversed.

As explained above, the neck ring drive device of the present invention fixes the cylinder head on the outside of the cylinder installed on both sides of the horizontal shaft, forms a contact surface on a part of the outside surface of the cylinder head, and The opening width of the neck ring can be changed to several levels by simply rotating the setting ring, which has a step-shaped inner surface on the cap fixed to both ends of the shaft, which is effective in shortening the time required to change product types.
