JPS585850B2 - Glass product reversal and take-out device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reversing and take-out device for glass products, and is particularly used when blowing glass products such as glass products with a small bottom area or wide-mouth bottles with rounded bottoms that cannot be stood upright. This invention relates to a reversing and taking-out device for glass products, which is capable of gripping the mouth of a bottle, inverting it, and taking it out onto a conveyor dead plate.

Generally speaking, to blow glass products such as wide-mouthed bottles with a small base area or rounded bottoms that cannot stand upright, the semi-finished products are finished by placing them in a rough mold and blowing air into them. It is necessary to transfer it to a mold for final shaping, and then remove the finished product onto a conveyor dead plate.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for reversing and taking out glass products, which is capable of grasping the opening of a glass container on a finishing die, inverting the container, and placing the container on a conveyor dead plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a glass product reversal and take-out device according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a fixed frame, and a cylinder body 2 is rotatably supported on this fixed frame 1.

This cylinder body 2 is integrally equipped with a gear 3 on its outer periphery, and has a first cylinder hole 5 inside with a partition wall 4 as a boundary.
and a second cylinder hole 6 are formed.

Further, a pedestal 7 is provided at the opening edge of the second cylinder hole 6 so as to project forward.

A piston shaft 8 is provided to pass through the centers of the first and second cylinder holes 5.6, and a first piston body 9 and a second piston are disposed on the axis of the piston shaft 8. The body 10 is axially spaced apart and arranged to be slidable within the first and second cylinder bores 5.6.

An annular groove 11 is formed on the end face of the first piston body 9 facing the partition wall 4, while an annular groove 12 is formed on the partition wall 4, and between the annular groove 11 and the annular groove 12, an annular groove 12 is formed on the partition wall 4. A spring 13 is incorporated in the cylinder body 1, and the spring force of the spring 13 always applies a force in the direction of drawing the piston shaft 8 into the cylinder body 1.

Note that ventilation holes 14 are formed in the partition wall 4 .

Further, the cylinder body 2 and the piston shaft 8 are connected by a spline joint S. C, they are linked so that relative movement in the axial direction is allowed but relative rotation is restricted, so that the rotation of the cylinder body 20 is transmitted to the piston shaft 8.

On the other hand, the bases of the two crank arms 15 and 16 are mounted on pins 17 on the pedestal 7 extending from the cylinder body 2.
．． It is rotatably pivoted by 18.

Of these, the crank arm 15 has two arms 20 extending in substantially the same direction around the boss 19 at a distance in the axial direction.
．． 21, while the crank arm 16 has a boss 22
It has two arms 23, 24 extending in substantially opposite directions at an axial distance around the.

To the arms 20 and 23, pawls 25 and 26, each curved symmetrically with respect to the center line XX perpendicular to the piston axis 8, are fixed by bolts, respectively. 26 is designed to grip the mouth of a molded glass product.

This pawl 25.26 is configured such that the gripping portion is located at a height H from the center 01 of the piston shaft 8, as shown in FIG. The center of gravity G of the glass product when gripped centering on 02
It is desirable to construct the piston so that it is at the same level as the center O1 of the piston shaft 8.

A bracket plate 27 is fixed to the tip of the second piston body 10, and the bracket plate 27 and the arm 21
The bracket plate 27 and the arm 24 are connected with a pin through a connecting link 28, while the bracket plate 27 and the arm 24 are connected with a pin through a connecting link 29.

In FIG. 1, reference numeral 30 indicates a dead plate of the conveyor, and the center 03 of this dead plate 30 is located symmetrically with the center 01 of the glass product P with respect to the center O1 of the piston shaft 8, that is, L1=L2 in FIG. in a relative position.

Therefore, when the piston shaft 8 rotates 180 degrees, the glass product P is inverted and placed on the dead plate 30 with its mouth facing down.

Therefore, the gear 3 of the cylinder body 2 is connected to the rack 31.
The rack 31 is driven by a pneumatic or hydraulic piston-cylinder arrangement, as shown in FIG.

That is, in FIG. 3, a rack 31 is formed at one end of a piston shaft 32, and a piston body 33 is supported at the tip of this piston shaft 32, and the piston body 33 itself is axially moved inside a cylinder 34. Built-in so that it can slide in the direction.

Since the present invention is configured as described above, the glass product P that has been finished being formed is transferred to the conveyor dead plate 30.
When flipping it upside down and taking it out, first, as shown in Figure 1,
The piston shaft 8 is moved against the spring force of the spring 13 in the direction of arrow A.
direction, drives the connecting link 28.29 and crank arm 15.16, moves the claw 25.26 in the direction of arrow B, and grips the opening of the glass product P.

Next, as shown in FIG. 3, the piston rod 32 is
direction to drive the rack 31 in the same direction.

Then, the gear 3 is rotated in the direction of arrow D, and the cylinder body 2 integrated therewith is also rotated in the same direction, and the rotation of the cylinder body 2 is caused by the spline joint S. Since the piston shaft 8 also rotates via C, the pawls 25 and 26 can rotate the glass product P.
18 with the center O1 of the piston shaft 8 as the center while grasping the
The glass product P can be turned over by 0 degrees and taken out onto the dead plate 30.

After that, when the pressing force on the piston body 9 is released, the piston shaft 8 is returned by the spring force of the spring 13, and the piston shaft 8 moves in the opposite direction of arrow A, opening the claws 25 and 26 and removing the glass. The grip on the product P is released, and the glass product P can be turned over and placed on the dead plate.

In this way, according to the present invention, the piston shaft is built into the cylinder body which can be rotated by the rack, and the movement of the piston shaft back and forth causes the piston shaft to rotate through the two crank arms pivotally mounted on the frame of the cylinder body. Since the mouth of the glass product can be grasped by opening and closing, the glass product in the finishing mold can be easily reversed and taken out onto the dead plate with a simple configuration. Turning operations around the axis can proceed simultaneously, reducing operation time and improving work efficiency.
