Description: TECHNICAL FIELD The present invention relates to a transfer device for hollow glass products that is continuously or intermittently transferred in a molding or processing / packaging process. The present invention relates to a transfer device having a structure suitable for transferring a hollow glass product having a substantially vertical cylindrical portion while positioning it at a predetermined position outside a conveyor or packing it in a packaging box.

(Prior Art) Generally, in a manufacturing process of a hollow glass product, a glass product being transferred by a conveyor may be transferred to the outside of the conveyor. For example, a glass product immediately after being molded by a glass molding machine is It is transferred to the layer for cooling.

As a conventional means for such transfer, as a method of transferring a plurality of row glass products transferred by a belt conveyor such as made of asbestos to a place of the same level or different levels, for example, A method is known in which the glass product transferred is slid by a push bar and transferred in the width direction of a mesh belt arranged so as to be flush with the entrance of the layer.

In addition, there are known methods such as a manual method, a method of making a slide with a head, a method of blowing off with air etc., a method of sucking with a vacuum, a method of gripping the outer or inner surface of a glass product with a chuck, and the like.

However, in any of the above methods, the glass product falls,
It is not always satisfactory in practice because it is scratched because it is uncertain to grasp and the device is expensive, and the position of transfer is decided at the time of transfer. In this case, it is desired to transfer the product in a positionable state, but it is difficult for a simple device to simultaneously position the glass products transferred in a random state by the transfer device at the same time. There was also a problem.

(Problems to be Solved by the Invention) The present invention has been made from the above viewpoints, and an object thereof is a relatively simple device, which does not damage a glass product and is reliable even when there is a step. The present invention is to provide a transfer device for a hollow glass product that enables various transfers.

Another object of the present invention is to accurately perform the positioning of a hollow glass product such as a general tumbler having a generally vertical cylindrical portion when positioning is required on the transfer side. The present invention is to provide such a transfer device.

Still another object of the present invention is to provide a hollow glass product transfer device that can be suitably used as an automatic packaging device for packing a plurality of hollow glass products in a packaging box.

(Means for Solving the Problems) The transfer device for a hollow glass product according to the present invention, which has been made to realize such an object, is characterized by a vertical cylinder type (for example, a cylinder type or a polygonal cylinder type). An outer support plate for supporting the outer surface that provides a substantially vertical wall plane for engaging the outer surface of the hollow glass product, and being inserted into the hollow of the glass product and approaching the outer support plate, An inner support block provided so as to be engageable with the inner surface of the glass product at a position facing the outer support plate, and an insertion movement of the inner support block into the hollow glass product and an approach movement to the outer support plate. A pair of the inner support block and the outer support plate in a state of holding the glass product, and an inner support block driving means for holding the glass product in cooperation with the inner support block and the outer support plate. In addition, it has a structure including a movement driving means for moving integrally. The posture of the substantially vertical wall plane of the outer support plate can be adjusted according to the shape of the glass product to be transferred, and for example, a tumbler or the like has an upwardly wide shape that is slightly open upward. Since it does not exist, it is set with an inclination that matches the outer surface of this shape.

Specific examples of the hollow glass products to be transferred in the present invention include cups, tumblers, stemware, carafe, bowls, etc., but are not particularly limited to these. .

Further, when the glass product targeted by the present invention is in a relatively high temperature state, the pair of outer support plate and inner support block for holding the glass product have sufficient heat resistance, and It is configured as something with the characteristics that can be handled softly (eg carbon cloth, asbestos, etc.),
In particular, for positioning a hollow glass product having a vertical cylindrical portion, a configuration in which the engagement surface of the inner support block with the glass product has a curvature larger than that of the inner peripheral surface of the glass product is preferably adopted. By the engaging surface of the inner support block,
According to the gripping operation, the glass product rolls with respect to the inner support block, and a kind of self-aligning action occurs, so that the glass product is accurately gripped at the position where the inner support block and the outer support plate face each other. Become.

Further, when the glass product targeted by the present invention is in a cold and low temperature state, the engaging surface portion of the inner support block (and also the outer support plate if necessary) is formed by an elastic body so that The effect can be obtained.

The outer support plate in the present invention provides a flat vertical wall surface as a surface for engaging the outer surface of the glass product,
The vertical wall surface forming the engagement surface is usually formed as a common flat surface with which a plurality of glass products are engaged when a plurality of target glass products are engaged.

(Operation) With the above-described configuration, the present invention improves the handling property during the transfer of the hollow glass product, and the transfer of the glass product to the front side of the transfer remains in the same random state as the conventional one. Therefore, the glass product can be grasped and the glass product can be accurately positioned on the transfer side.

Particularly when the transfer device of the present invention is applied as a part of an automatic boxing device, since positioning of a hollow glass product having a vertical cylindrical portion is performed extremely well and accurately, it is often reliant on human hands. Automated box packaging can be realized.

(Example) Hereinafter, the present invention will be described based on an example shown in the drawings.

Drawing is a figure showing an example of composition outline of a hollow glassware transfer device by the present invention, Drawing 1 is a front view showing the state before grasping glassware, Drawing 2 is a front view of the grasping state, Three
The figure is a side view of the same, and FIG. 4 is a diagram for explaining a transfer state.

In the figure, reference numeral 1 is a first support frame that is integrated with a pedestal 14 and a second support frame 13. The upper end of the first support frame 1 is bent and extended forward to form a ball joint 2 and a turn. A mechanism for guiding the inner support block (hereinafter referred to as a tongue) 8 during driving is suspended via the buckle 4. A linear ball slide cylinder 3 and a slide plate 5 integrated with the linear ball slide cylinder 3 are assembled on the front surface of the vertical portion of the first support frame 1 so as to be movable in the vertical direction. Upward and downward movement is performed by inputting air pressure.

This linear ball slide cylinder 3 has the above-mentioned tongue 8
Is configured to drive the.

Further, in the present embodiment, a tumbler support (outer support plate) 9 is provided in a lower portion of the gantry 14 which is integrated with the first support frame 1.
Is fixedly assembled. The tumbler support 9 is a support head 9a having a posture that is substantially vertical (slightly upwardly inclined) to the front surface of a shaft portion that extends horizontally from the gantry 14.
Is fixed. This support head 9a in this example
Are dimensioned to have a suitable horizontal length for gripping two tumblers in parallel as shown in FIG. 3 or FIG.

Next, the structure of the tongue 8 which is one of the grasping arms for grasping the tumbler and the drive mechanism (inner support block drive means) thereof will be described. The tongue 8 in the present example is a slide unit integrated with the linear ball slide cylinder 3. A pair of left and right bearing units 6 fixed to the front surface of the plate 5 rotatably supports the tongs rotating shaft 7, and a pair of tongs arms 8a is non-rotatably attached to the tongs rotating shaft 7 and the tongs rotating. A link that is also non-rotatably attached to the shaft 7.
12 is provided and is rotatably connected to the joint link 10 at the lower end of the turnbuckle 4 at an eccentric position via a pin 11. Reference numeral 15 is a tong head fixed to the tip of the rotating arm 8a of the tongue 8 so as to engage with the inner surface of the tumbler A which is the glass product.

With such a configuration, the tongue 8 operates as follows.

That is, first, with respect to the tumbler that has been brought into the state (state before gripping) shown in FIG. 2 by the transfer of the predetermined tumbler A, the lower motive power is externally input to the linear ball slide cylinder 3, and the linear ball slide cylinder 3 and The slide plate 5 is moved down. As a result, the slide plate 5 and the tongue rotation shaft 7 supported by the tongs rotation bearing unit 6 are moved downward. At this time, the joint link 10 at the lower end of the turnbuckle 4 has the first
Since it is fixedly supported by the support frame 1 of
Following the downward movement of the tongue rotary shaft 7, the link 12 is rotated around the pin 12, thus causing the rotation of the tong rotary shaft 7.

As a result, the tongue 8 causes a hyperbolic movement as shown by an arrow in the figure in which the downward movement and the rotation of the tongue rotation shaft 7 are combined, and the tongue head 15 at the tip thereof is inserted into the tumbler and further on the inner surface. Engage.

By this insertion and engagement, the tumbler A is slightly moved toward the external support head 9a and finally gripped by the tongue head 15 and the support head 9a. In this operation, it goes without saying that the engagement surfaces of the tongue head 15 and the support head 9a with the tumbler A have a sufficient shape and surface condition necessary for gripping.

When such a gripping operation is performed, as shown in FIG. 5, even if two tumblers A arranged in parallel are moved to the position of the transfer device with a slight positional deviation. , These tumblers A support head when gripping
The tumbler A rolls with respect to 9a and is automatically aligned, and the positions of the two tumblers A are always grasped at accurate intervals.

If the two tumblers A can be grasped in the accurately positioned state as described above, the apparatus including the above-mentioned grasping mechanism can be transferred and driven by the transfer driving means such as an air cylinder as shown in FIG. The packaging box 16 prepared at a predetermined position can be accurately boxed. Alternatively, it is transferred onto the layer 17 for slow cooling as shown in FIG.

The present invention is not limited to the embodiments described above, and can be implemented in various modified forms. For example, the glass product may be other than a tumbler, and the number of glass products may be one instead of two, or may be three or more. In particular, as the number increases, the effect of the present invention, which enables gripping and transferring while maintaining their accurate positional relationship, is extremely large. Further, although the transfer device of the present invention has an excellent effect when applied to an automatic packaging device for glass products, it goes without saying that the transfer device is not limited to this and can be used for transfer in other steps.

(Effects of the Invention) As described above, according to the hollow glass product transfer device of the present invention, a reliable transfer can be performed with a relatively simple device without damaging the glass product and even when there is a step. When the target is a hollow glass product such as a general tumbler having a substantially vertical cylindrical portion, it is possible to achieve an accurate positioning on the transfer side.

Further, when the present invention is applied as an automatic box packaging device for a plurality of hollow glass products, it is extremely excellent in practical use because it can improve the transfer handling property and can perform accurate positioning on the transfer side.
