Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for applying a blue treatment to a glass bottle, which allows the flame treatment to be applied to the glass bottle reliably and safely.

[Technical background of the invention and its problems] Conventionally, a glass bottle is taken out from a glass bottle forming machine and placed on a conveyor, and its position is detected by a sensor, and powder, gas, etc. for bloom processing are placed on the conveyor. Bloom treatment is performed by dropping or spraying into a bottle, or bloom treatment is performed by providing a tunnel filled with bloom treatment gas etc. on the conveyor and passing through this tunnel. Was.

However, as the number of glass bottles to be treated increases due to mass production, bloom treatment tends to be incomplete, and it becomes difficult to perform bloom treatment reliably on glass bottles. Because of the leakage of gas and gas, pollution is likely to occur, and the cost of pollution prevention equipment to prevent this is large and uneconomical. In order to solve these problems, for example, a method for introducing a chemical resistance improving gas into a glass container and the inside of the device were invented, as described in JP-A No. 49-59813. However, when introducing the chemical resistance improving gas into the glass container, the gas injection port is not inserted into the container, making it difficult to smoothly introduce the gas into the container.
Because the gas exhaust port does not reliably close the mouth of the container, gas leaks outside the container, making it difficult to efficiently feed the gas, and making it difficult to reliably suck up the residual gas in the container, leaving gas in the container. In addition, there were problems such as leakage, which would increase gas consumption and become uneconomical. [Purpose of the invention and summary of the invention] Therefore, the present invention solves the above-mentioned problems that existed in the past, and also makes it possible to reliably and quickly apply bloom treatment to a large number of glass bottles during the glass bottle molding process. It was created with the aim of making it possible to perform bloom treatment with excellent economic efficiency and efficiency, and also to reliably prevent the occurrence of pollution. During the glass bottle molding process, in which the opening of the glass bottle is held by the holding part of the tong head of the take-out tongs, and the glass bottle is moved and placed on the death plate, the holding part of the tong head of the take-out tongs is used. In conjunction with the operation of clamping the mouth of the glass bottle, a composite nozzle body including an ejection nozzle and a suction nozzle is lowered toward the glass bottle, and the suction nozzle closes the mouth of the glass bottle. The tip of the elongated cylindrical injection nozzle is inserted into the glass bottle, and while the glass bottle is being moved to the detox plate, bloom treatment gas is injected directly into the glass bottle from the injection nozzle tip, and at the same time. Alternatively, after a slight delay, the gas ejected into the glass bottle is started to be sucked in by the suction nozzle at the mouth of the glass bottle, and even after the gas ejection is stopped, the remaining gas in the glass bottle is sucked in by the suction nozzle. This is a summary.

[Embodiments of the invention] Hereinafter, one embodiment of the present invention will be described as follows.

The apparatus used in the method of the present invention clamps the mouth of the glass bottle K formed in the finishing mold S and moves it to the detatch plate P.
The take-out tongs A to be placed are equipped with a cylindrical suction nozzle 2 that can close the mouth of a glass bottle K, and an elongated cylindrical jet nozzle 1 that can insert its tip into the glass bottle K. A composite nozzle body B consisting of a glass bottle K is attached so as to be lowered toward the mouth of a glass bottle K in conjunction with the clamping operation of the take-out tongs A. The take-out tong A includes a frame body 10 and a pair of link bodies 11, 1.
2, a link shaft 13, a fixed shaft 14, flat links 15, 16, and a pair of tongue heads 17, 18.

are connected.

The pair of link bodies 11 and 12 are swingably supported by the frame body 10 via a fixed shaft 14, and are further supported by a four-link pin 2.
The link bodies 11 and 12 are connected to the lower end portion of the link shaft 13 via flat links 15 and 16 that are connected through the
is formed to swing in an opening/closing manner around a fixed shaft 14.

Further, on each of the link bodies 11 and 12, there are provided tongue heads 17 and 18 provided with approximately half-cylindrical holding portions 17a and 18a that match the opening of the glass bottle K and directly hold it. They are attached to each other through the Horizontal shaft 19
is pivotally supported by the lower end portion of the link shaft 13, and
The upper end portions of the flat links 15 and 16 are swingably supported, and support shafts 20 and 21 are connected to both ends of the flat links, respectively. Installed linear motion bearing 2
The upper end portion thereof is attached to the frame 10 so as to be able to slide freely in the vertical direction via the frame member 2 .

The composite nozzle body B is connected and fixed to the lower ends of the support shafts 20 and 21 by appropriate means, and the composite nozzle body B can be moved up and down in conjunction with the link shaft 13. The composite nozzle body B also includes a suction pipe 4 in the shape of a rectangular vibrator, a cylindrical suction nozzle 2 protruding from the lower part of the suction vibrator 4, and an ejection vibrator in the shape of a round vibrator installed inside the suction vibrator 4. 3, and an elongated cylindrical ejection nozzle 1 that communicates with the ejection vibrator 3 and is connected in a hanging manner. At the same time, it is provided so as to protrude considerably downward from the lower end peripheral edge of the suction nozzle 2, and is formed so that the gas G can be ejected to every corner within the glass bottle K.

Moreover, a plurality of ejection nozzles 1 can be attached to one suction nozzle 2 in accordance with the shape of the glass bottle K, such as two for double-cob and three for triple-cob. Further, the suction nozzle 2 is configured such that the outer circumferential surface of its lower end portion is in close contact with the inner circumferential surface of the upper end portions of the holding portions 17a and 18a, so that the gas G does not leak. The timing at which the gas G is ejected or sucked into the glass bottle K from the ejection nozzle 1 may be adjusted using the timing drum of the glass bottle making machine, or the timing may be adjusted using the take-out tongs A. The timing may be adjusted by detecting the operating air pressure and then delaying it with a timer.

Further, this timing is configured so that it can be freely changed electrically by the control panel 32 until the glass bottle K formed in the finishing die S is held and moved to and placed on the dead plate P. has been done. In the figure, 24 and 28 are a fixing pin and a connecting plate for attaching the composite nozzle body B to the lower end of the support shafts 20 and 21, and 25 is a fixing pin and a connecting plate through which a mounting bolt 26 is inserted to remove the take-out tongue A. A mounting hole is provided to allow one mounting, and 27 is a bolt.

Next, to explain the method according to the present invention, first, the finishing mold S
Take out the mouth of the glass bottle K with tongs A.
The flat link 15 is pivotally supported on the lower end portion of the link shaft 13 via a horizontal shaft 19 by sliding the link shaft 13 downward so as to be held between the tongue heads 17 and 18 of the tongue heads 17a and 18a. 16, the pair of link bodies 11, 12 are swung closed around the fixed shaft 14, and the support shafts 20, 21 are slid downward via the horizontal shaft 19, thereby forming the composite nozzle body B. is lowered toward the mouth of the glass bottle K (see Figure 2).

Furthermore, the holding parts 17a, 18a of the tongue heads 17, 18
The mouth of the glass bottle K is held between them, and the tip of the jet nozzle 1 is inserted into the glass bottle K, and the mouth of the glass bottle K is closed with the suction nozzle 2.

Then, gas G (SO2) for bloom treatment is ejected from the ejection tank 30, through the ejection vibrator 3, and from the tip of the ejection nozzle 1 into the glass bottle K (see Fig. 3 and Fig. 6), and simultaneously or slightly. Gas G is ejected into glass bottle K after a delay.
The gas G ejected from the tip of the ejection nozzle 1 circulates evenly within the glass bottle K and is sequentially sucked into the suction nozzle 2.

Thereafter, the ejection of gas G is stopped, and the remaining gas G in the glass bottle K is all sucked in by the suction nozzle 2 (see Fig. 4), and the gas G is collected in the suction tank 31 via the suction vibrator 4 (
(See Section 6). Then, place the glass bottle K onto the detouching plate P.
When the glass bottle K is moved and placed, the link shaft 13 is slid upward to release the opening of the glass bottle K from the holding parts 17a and 18a, and the composite nozzle body B rises to remove the glass bottle. Move away from the mouth of K (see Figure 5) and repeat the same process again.

[Effect of the invention] Therefore, according to the method according to the present invention, the gripping portions 17a, 18 of the tong heads 17, 18 of the take-out tongs A
A large amount of glass bottles K can be efficiently bloomed while finishing the glass bottle K by holding the opening of the glass bottle K. It will be extremely good.

Moreover, the tong head of takeout tong A is 17,
Since the opening of the glass bottle K is held between the holding parts 17a and 18a of 18, the position of the glass bottle K is determined accurately, and the tip of the spout nozzle 1 can be reliably inserted into the glass bottle K. The mouth of the bottle K can be accurately closed with the suction nozzle 2, and there is no possibility that the gas G ejected from the tip of the ejection nozzle 1 will leak out of the glass bottle K. In particular, the gas G is ejected from the tip of the ejection nozzle 1 inserted into the glass bottle K, and at the same time or with a slight delay, the glass bottle K
The gas G spouted into the glass bottle K begins to be sucked in by the suction nozzle 2 at the mouth of the glass bottle K, so the gas G spouted from the tip of the spout nozzle 1 is smoothly circulated inside the glass bottle K and sequentially sucked in by the suction nozzle 2. This makes it possible to apply the bloom treatment to the glass bottle K easily and evenly. Furthermore, even after the ejection of the gas G is stopped, the residual gas G in the glass bottle K is sucked in by the suction nozzle 2, so the gas G
does not remain in the glass bottle K, thereby reliably preventing the occurrence of pollution.

Furthermore, take-out tongs A tong head 17,1
Since the composite nozzle body B is raised and lowered in conjunction with the operation of clamping the glass bottle K with the clamping parts 17a and 18a of 8, the composite nozzle body B is located above and becomes a hindrance except when performing bloom processing. It becomes possible to install the relatively long ejection nozzle 1 without any risk, and the tip of the ejection nozzle 1 can be inserted deeply into the glass bottle K, allowing the gas G for bloom treatment to be efficiently introduced into the glass bottle K. , and it becomes possible to reliably eject from every corner 5. As explained above, according to the present invention, it is possible to perform bloom treatment on a large amount of glass bottles reliably and quickly, and also to reliably prevent the occurrence of pollution, with good work efficiency and economical bloom treatment. Excellent effects such as being able to perform O operations can be obtained.
