[Detailed description of the invention] (a) Industrial application field The present invention relates to an improvement of a gob transfer device that transfers gobs (molten glass lumps) that are cut and taken out from the orifice of a melting furnace to a blowing process. . (b) Problems to be solved by conventional techniques and ideas In the glass forming process, as shown in Figure 9, the molten glass flowing down from the orifice of the melting furnace is cut one after another by the shear 2, The resulting molten glass gob (gob) 3 is supplied to a glass bottle making machine via a transfer device 4. The transfer device 4 usually includes a scoop 5,
It consists of a trough 6 and a deflector 7, but may also include an intermediate funnel 8. In such a transfer device, a lubricant such as graphite or lubricating oil is applied to the contact surface or supplied by drip, etc. to improve the slippage when the gobs come into contact with each other during transfer. However, when the gob, which is a lump of high-temperature molten glass, comes into contact with graphite or lubricating oil, it burns and embers (carbide) get mixed into the gob, causing black spots on the formed glass product (this is called carbon ) was the cause. In addition, contact between the gob and graphite or lubricating oil can cause temperature unevenness in the gob, resulting in oroshi (a phenomenon in which the surface of a product formed like a hammer becomes jagged) and tora (a phenomenon in which the surface of a formed glass product becomes jagged). A type of uneven thickness phenomenon occurs in which thick and thin parts are formed on the surface. In addition, in the case of a glass bottle making machine such as an IS machine which has a large number of blowing devices, there is a problem in that the gob-in occurs later at both sides than at the center due to its geometric structure. In order to solve the above problem, a large number of air ejection holes are provided in the transfer device, especially on the contact surface of the scoop with the gob, and compressed air is ejected from these holes to form an air film between the contact surface of the gob and the scoop. A technology has been developed that eliminates the need to supply lubricants such as graphite (Utility Model Application Publication No. 160232/1983). However, the diameter of the air nozzle in Utility Model Application Publication No. 160232/1982 is large, ranging from 0.5 mm to 3 mm, and the air nozzle is perpendicular to the transfer surface, so the air film (air jet) that can securely hold the gob is In addition, there is a problem that the gob may fly out of the transfer device due to a sudden blowout of air. 58−
It was verified that the device of No. 160232 was not suitable for practical use. (c) Means for solving the problem The inventors of the present invention have repeatedly conducted research on the air nozzle forming the gob contact surface of the transfer device, and have reached the following conclusion. If the air nozzle is 0.1mm or less, it will become clogged and the air cushioning effect will be lost.
The optimal diameter of the air nozzle should be 0.1 mm or more, and the direction of the air nozzle should be toward the center and the transfer direction, but the angle of inclination should be 60 degrees or more with respect to the gob transfer direction. Then, the gob will fly out from the transfer device and the air compression effect will disappear. If the angle is less than 20 degrees, the air compression effect will also disappear. Therefore, it is optimal for the inclination angle to be between 20 degrees and 60 degrees with respect to the gob transfer direction. I found that. Incidentally, although it is desirable that air jet holes be provided in all of the members constituting the gob transfer device, it is not necessary to do so. (d) Function and effect As shown above, the diameter of the air nozzle is
If the diameter is 0.1 mm or more, the air jet hole is inclined at an angle of 20 degrees or more and 60 degrees or less with respect to the transfer direction, and the air jet hole is formed toward the center, the air cushion layer will be reliably formed. Good centering can be obtained. In addition, since the air hits the gob from the back side, the propulsion force of the air increases the gob transfer speed, provides good centering, and prevents the gob from flying out from the transfer device. As a result, there is no need to use a lubricant such as graphite or lubricating oil in the gob transfer device, and the incidence of carbon, slag, and other particles caused by this can be reduced. In addition, the propulsion force of the air increases the transfer speed of the gob and makes it possible to control the speed, which improves the rotation rate of the glass molding machine and eliminates the gob-in delay on both sides of the glass bottle making machine. be able to. (e) Embodiment FIGS. 1 to 8 are diagrams of an embodiment of the present invention, in which a scoop 5, a trough 6, and a deflector 7 are provided with air jet holes 8 for compressed air.
An example is shown below. 1 and 2 show a scoop 5, and a large number of air ejection holes 8 are formed in the contact surface 9 of the scoop 5 with the gob, as shown in the figures. As shown in FIGS. 2A and 2B, this air jet hole 8 is oriented toward the center, and as shown in FIG.
The angle is set to 30 degrees, and its diameter is approximately 0.3 mm. Air flows from the air hole 10 to the chamber 11
It is then ejected from the nozzle 8. FIG. 3 shows the trough 6, as shown in the figure.
Inclination angle β of the air jet hole 8 with respect to the gob transfer direction
Since it is almost the same as scoop 5 except that the angle is set to 45 degrees, the explanation thereof will be omitted. 4 to 8 show the deflector 7,
The air jet hole 8 formed in this has an inclination angle γ of 30 degrees with respect to the transfer direction, similar to the scoop, and a diameter of about 0.3 mm, but as shown in the figure, unlike the scoop 5 and the trough 6, , air outlet 8
Areas in which a is formed and areas in which it is not formed are arranged alternately. In Fig. 7, the interval a between the spans is 5 mm and the interval b is 10 mm. (f) Test example Using the gob transfer device of the present invention using the scoop 5, trough 6, and deflector 7 shown in Figures 1 to 8, 3456 glass bottles with a capacity of 500 ml and a weight of 425 g were sampled, and For comparison, 3408 glass bottles of the same volume were sampled using a conventional gob transfer device drip-fed with lubricating oil. When the two types of glass bottles obtained were compared and quality inspected, as shown in the table below, the number of defective glass bottles using the transfer device of the present invention was significantly reduced, confirming its effectiveness. 【table】
