DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle oscillating apparatus, and particularly to applying an ultrasonic vibration to a bottle such as a beer bottle to an outer bottom portion of the bottle by an ultrasonic oscillator in an ultrasonic irradiation tank. The present invention relates to a device for rocking a bottle before irradiation with ultrasonic waves when detecting a leaked product by foaming a filling material such as beer.

[0002] Conventionally, as a method for detecting leaks of bottle products such as beer bottles, a flavored bottle is irradiated with ultrasonic waves from the outer bottom to foam the bottle, and the amount of foam present in the empty space at the top of the bottle is measured with a camera. In some cases, a leak is detected by measurement (see, for example, Japanese Utility Model Laid-Open No. 6-72039). However, foaming of beer itself is an extremely important factor in detecting this type of leaked product. To ensure foaming, be sure to irradiate high-power ultrasonic waves to the outer bottom of the bottle. Or the irradiation time had to be very long.

[0003] By the way, in order to easily foam beer, it is known that if bubbles of carbon dioxide gas are generated from the beer in a previous step of irradiating ultrasonic waves to the beer, the beer is likely to foam thereafter. Was.

Therefore, conventionally, as shown in FIG. 4, a pair of erection members 108a and 108b are respectively provided on the conveyors 1a and 1b.
06a and 106b are disposed to face each other, and a bottle B such as a beer bottle is vertically sandwiched between the conveyors 106a and 106b to be conveyed in a predetermined direction.
Impact bodies 110a and 110 each having
A method has been adopted in which a predetermined impact is applied to the bottle by an impact device 3 made of Ob to promote foaming (for example, see Japanese Utility Model Laid-Open No. 6-72039).

[0005]

However, in such a conventional bottle rocking apparatus, when bottles are conveyed at a high speed of 600 bottles per minute, the arrangement of the bottles is vertically aligned in the conveying direction. In the case of single-row conveyance, since the variable speed width of the conveyance conveyor was extremely large, an impact force corresponding to the conveyance speed could not be applied to the bottle. For this reason, even if foaming is promoted, there is a risk that the bottle will fall over. Also, in bottles that are arranged side by side in the width direction of the conveyor, so-called multi-row conveyance, it is difficult to apply an impact force to the bottles. There is a design defect that requires a large installation space.

Therefore, the bottle swinging device of the present invention has been made in view of such problems of the conventional bottle swinging device, and has a simple structure to control the flow of bottles conveyed on a conveyor. A vibrator is applied to the opening / closing guide to prevent it from vibrating, so that the bottle is reliably swung, foaming is promoted and is not affected by the conveying speed of the conveyor, and it can handle single-row and multi-row conveying of bottles. An object of the present invention is to provide a bottle swinging device in a bottleless leak inspection device.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a bottle conveying conveyor, an ultrasonic irradiation tank provided with an ultrasonic oscillator for irradiating an ultrasonic wave to the outer bottom of the bottle, and an ultrasonic irradiation tank in or above the ultrasonic irradiation tank. It is composed of a pair of open / close gates disposed immediately before and in contact with the transfer surface of the transfer conveyor, and vibrators respectively attached to the open / close gates.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a bottle swinging device in a leak detecting device according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, a bottle rocking apparatus 1 used in a bottle leak detecting apparatus according to the present invention employs an ultrasonic vibrator (not shown) provided at an outer bottom portion of a bottle B. Is provided in the ultrasonic irradiation tank 20 for irradiation. That is, the bottle rocking apparatus 1 is located in the middle of the transport conveyor C that transports the beer bottles B in a single row or multiple rows in a predetermined direction indicated by an arrow in FIG. A pair of open / close guides 2a,
2b. The bottles B being conveyed by the conveyor C are temporarily blocked by the opening and closing guides 2a and 2b, and are reliably swung by vibrators 6a and 6b disposed on the back of the opening and closing guides 2a and 2b immediately before ultrasonic irradiation. It has become.

The openable / closable guides 2a and 2b are composed of a pair of guide plates, and are fixed to frames 11a and 11b arranged on floors (FL) of a factory.
b is openable and closable by a pair of air springs (air cylinders) 3a, 3b disposed on a bracket 16 mounted on the bracket 16 via vibration isolating pads 14a, 14b, 15a, 15b. These air cylinders 3a, 3b
One end is pivotally attached to the air cylinder receiving pivots 4a, 4b fixed on the bracket 16, and the other end is pivotally attached to the shafts 10a, 10b via a link mechanism. The devices such as the air cylinders 3a and 3b are covered by an air cylinder cover 12 for protection. And
Pibbles 6a, 6b are respectively attached to the backs of the pair of opening / closing guides 2a, 2b, and a predetermined vibration is generated by energizing from the electric wires 7a, 7b.
a, 2b. Further, from the frames 13a, 13b, stoppers 8a, 8b are arranged in the width direction of the conveyer C and behind the opening / closing guides 2a, 2b to regulate the maximum opening of the opening / closing openings 2a, 2b. .

Further, the pair of guide bars 9a and 9b guides the bottle B up and down in a predetermined direction in consideration of the multi-row conveying width of the bottle B in the place of the conveyor C in parallel with the bases 11a and 11b. It is provided so that it may be conveyed.

In the bottle swinging device 1 used in the bottle leak detecting device of the present invention thus constituted, as shown in FIG. , And sequentially transported in the direction of the arrow. Then, just before the bottle B enters the ultrasonic irradiation tank 20, the opening / closing gates 2a, 2b are closed by operating the air cylinders 3a, 3b to prevent the bottle B being conveyed from entering. When an air spring is used in place of the air cylinders 3a and 3b, the opening / closing gates 2a and 2b are always closed, and when the bottle B is conveyed, the opening / closing gates 2a and 2b are appropriately pressed. Expand to accommodate changes in bottle volume. A vibrator 6a attached to the back of the opening / closing gates 2a, 2b,
6b is energized by the electrical arrangements 7a and 7b to be activated to apply a predetermined vibration to the open / close gates 2a and 2b. As a result, this vibration propagates to many bottles B that are in contact with the inside of the opening / closing gates 2a and 2b, and the bottle B reliably vibrates and oscillates, thereby generating carbon dioxide gas bubbles from the beer content. Thereafter, the ultrasonic vibrator in the ultrasonic irradiation tank 20 is vibrated to irradiate the bottom of the outer surface of the bottle B with ultrasonic waves to foam the filling such as beer. Then, the amount of foam in the empty portion at the top of the bottle B is measured with a camera or the like to detect a leaked product. In this way, the flow of the entire bottle B is stopped on the conveyor C, and the leak from the bottle B is continuously detected.

[0013]

According to the bottle rocking apparatus of the present invention, foaming from the contents of bottle products such as beer is promoted very easily and reliably. In addition, a large number of bottles can be reliably swung simultaneously without being affected by the transport speed of the conveyor that transports the bottles. Also, there is no falling bottle. Furthermore, the present invention can be applied to both cases where bottles are conveyed in a single row or in multiple rows, and is extremely useful as a bottle swinging device of a leak detection device.
