Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improved technique for a molten glass distributor installed in a bottle making machine or the like.

[Conventional technology]

The above-mentioned molten glass distributor generally attaches a scoop for introducing a gob to a funnel rotatably by engaging a pinion continuous with the scoop with a sliding rack, and a driving means for sliding the rack on the rack. If the bottle is a large bottle, the funnel with one large scoop for introducing the large diameter gob is attached to the base, and the bottle is a small bottle. In this case, instead of the funnel provided with the large-diameter scoop, a funnel provided with two or three small-diameter scoops for introducing the small-diameter gob is attached to the base.

That is, by changing the funnel, a large-diameter single gob distribution form and a small-diameter double or triple gob distribution form are selected.

[Problems to be solved by the invention] However, since the weight of the funnel alone having the above-mentioned scoop is 15 Kg to 20 Kg, it takes two or three people to perform the replacement work of the funnel. There was room for improvement because it was labor-intensive, time-consuming, and dangerous, and it was necessary to prepare multiple types of expensive funnels with different scoops, which resulted in high equipment costs. .

The present invention has been made in view of the above circumstances, and it is possible to easily and safely perform the changeover of the single gob distribution mode and the double or triple gob distribution mode in a short time, and also to reduce the cost. The object is to provide a molten glass distributor which can be achieved.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a scoop for introducing a gob, which is rotatably attached to a funnel by engaging a pinion continuous with the scoop with a sliding rack, and a driving means for sliding the rack. In a molten glass distributor which is interlockingly connected to the rack, the funnel is divided into a funnel body having a rack and a scoop unit rotatably having a scoop, and the scoop unit is provided with the funnel body. It is characterized in that it can be replaced with a scoop unit having a number of scoops different from the number of scoops.

[Action]

According to the above characteristic structure, the molten glass distributor can be changed to a single-gob and a double-gob or a triple-gob distribution mode by exchanging the scoop unit according to the size of the bottle-making target.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 and 2 show a double gob distribution type molten glass distributor 1, in which 2 is a funnel pivotally mounted on the upper surface of a bottle making machine frame 3 about a vertical axis 4, 2 small scoops for introducing small gobs 5,5
Are each rotatably provided around the vertical axis.

Reference numeral 6 is a rotating means composed of a cylinder for rotating the funnel 2 around the vertical axis 4, and is used for maintenance of the upper and lower devices of the funnel 2 and the like.
Are provided to evacuate the maintenance space.

Reference numeral 7 denotes a rack that meshes with a pinion 8 that is connected to the scoops 5, 5 that is slidably held by the funnel 2 and that has an end portion side of a shaft member 9 that forms the rack 7 protruding from the funnel 2. A cam follower 11 is provided on the projecting end via a bracket 10.

Reference numeral 12 denotes a driving means for sliding the rack, and for example, a pulse motor M whose rotation direction and rotation angle are controlled is provided on the upper surface of the bottle manufacturing machine frame 3, and an output shaft 13 of the pulse motor M is provided with a lever body 14. And the lever body 14
A long groove 15 into which the cam follower 11 is movably fitted is formed at the free end portion of the.

According to the above configuration, the rack 7 slides due to the swing of the lever body 14 accompanying the rotation of the pulse motor M, and the two scoops 5, 5 move in the same direction as the rack 7 slides. It is rotated by a predetermined angle.

In the molten glass distributor 1 having such a structure, as shown in FIG. 3, the funnel 2 is a funnel main body 2A having a rack 7 and the scoop having the two scoops 5 and 5 rotatably. The scoop unit 2B is divided into a unit 2B, and the scoop unit 2B is detachably attached to the funnel body 2A via a stop bolt a.

Thus, as shown by the phantom line in FIG. 3, one large-diameter scoop 16 for introducing the large-diameter gob is rotatably provided, and the connecting portion is formed in the same shape as the scoop unit 2B. Prepare another scoop unit 2C, remove the scoop unit 2B from the funnel body 2A, engage the pinion 8 of the large-diameter scoop 16 with the rack 7, and fasten the other scoop unit 2C to the funnel body 2A by bolt a. Thus, as shown in FIG. 4, the molten glass distributor 1 can be modified into a single gob distributor type.

Alternatively, as shown by the phantom line in FIG. 4, another scoop unit 2D having three smaller-diameter scoops 17 for introducing a smaller-diameter gob is rotatably prepared, and the pinion 8 of the scoop unit 2D is prepared. By attaching the separately prepared small-diameter scoop 17 to the funnel body 2A in the state of being engaged with the molten glass distribution device 1, the molten glass distribution device 1 can be reconfigured to a triple gob distribution type.

[Effect of device]

As described above, according to the molten glass distributor of the present invention, a single gob and a double gob or a triple gob can be distributed by exchanging a plurality of types of scoop units having different numbers of scoops as needed. Can be taken.

Moreover, since the change of the distribution form is only the replacement of the scoop unit, the replacement operation itself is simple, and the operation can be performed safely and quickly by one person alone.

Furthermore, since only the scoop unit is required to change the distribution form of the gob, and the main components that make up the molten glass distribution device are used as they are, compared to the conventional mode in which the entire funnel is replaced. As a result, the equipment cost has been significantly reduced, and as a whole, the object of the present invention has been achieved by an extremely simple and rational improvement technique.
