BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leak detecting device for a container, in which leak of a container in which a foaming liquid such as a carbonated beverage is hermetically sealed is detected by utilizing ultrasonic vibration. The present invention relates to an auxiliary foaming device in a leak inspection device for shortening the time and stabilizing it.

2. Description of the Related Art Conventionally, as a leak in a container in which a foaming liquid such as a carbonated beverage is hermetically sealed is detected by oscillating ultrasonic waves, a filling liquid is filled and a cap is capped. Of a container provided with a container transport mechanism for transporting the container, a reservoir provided below the container transport mechanism for storing a liquid, and an ultrasonic oscillating device provided in the reservoir for oscillating ultrasonic waves. In the leak inspection device, the container can be conveyed by the container conveying mechanism on substantially the same plane, and the side wall of the storage tank is extended above the container conveying surface of the container conveying mechanism, and the side wall is extended. To form an opening for allowing the container transport mechanism to penetrate substantially in the same plane, and also to provide a liquid supply means for supplying a liquid to the storage tank,
The liquid supplied from the liquid supply means into the storage tank overflows from the opening, and the liquid level in the storage tank is maintained at a position higher than the container transfer surface. Leak inspection device (see Japanese Utility Model Laid-Open No. 2-48841)
Exists.

However, in the above-described conventional container leak inspection apparatus, even if the lid has a poor seal, a visible amount of bubbles or liquid does not leak from the seal portion. As long as it is difficult to detect a leak. Further, when the gas pressure of the foamable liquid in the container is low, there are many problems such as a large amount of ultrasonic wave output being required because vibration is applied from the bottom of the container. In addition, the capped carbonated drink is passed through the ultrasonic vibrator for leak inspection, but there is variation in the time from when the capped carbonated drink is put into the foaming tank until it foams. There was a problem that the number of aircraft was increased to cope with it (in other words, it was necessary to take a long transit time). In view of these circumstances, the present invention provides a leak inspection apparatus equipped with an impact device before the container enters the foaming tank or on the foaming tank so that the container and the internal solution are impacted with each other to create a state in which foaming easily occurs. It is an object of the present invention to provide an auxiliary foaming device in.

[0004]

In order to solve the above-mentioned problems, the present invention applies ultrasonic oscillation to a container in which a foaming liquid such as a carbonated beverage is hermetically sealed to foam the liquid in the container,
In a device for detecting a leak of a container, a technical means is adopted which is provided with an impact device that abuts against the container and gives an impact before reaching the ultrasonic generator or on the ultrasonic generator.

[0005]

As a result of adopting the above technical means, the present invention gives a shock before the container enters the foaming tank in which the ultrasonic wave generator is installed, or by contacting the container containing the internal solution on the foaming tank. In the foaming tank in which the ultrasonic wave generator is installed, the time until foaming is shortened and stabilized in an easily foamable state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The embodiment shown in FIG. 1 is a schematic front view showing a container leak inspection device provided with an impact device according to an embodiment of the present invention. FIG. 2 is a schematic plan view of the embodiment shown in FIG. First, the overall image will be briefly described with reference to FIG. 1 and FIG. Of the impacting device 3 which abuts the container 1 filled with the foamable liquid and which gives an impact, a storage tank 4 provided below the container transporting device 2 for storing the liquid, and this storage tank 4 And a ultrasonic wave generator 5 that oscillates an ultrasonic wave. Next, an embodiment of the present invention will be described in detail. The container transporting device 2 transports the container 1 filled with the foamable liquid that has been filled with the liquid from the liquid filling step, and a leak for performing a liquid level check is performed. It extends to the inspection process. Further, the container transporting device 2 mounted between the sprockets mounted on the machine frame 7 has a container transporting carrier between a pair of endless chains in the storage tank 4 provided with the ultrasonic wave generator 5. The container 1 is conveyed by the conveyor 6. It should be noted that the screw for indexing the container 1 filled with the foamable liquid to be conveyed at an appropriate pitch, the ultrasonic wave generator 5 and the storage tank 4 in which the ultrasonic wave generator 5 is installed are conventionally known ones. Therefore, detailed description is omitted. Then, the container 1 filled with the foamable liquid is
As it is conveyed by the container conveying device 2, it comes into contact with the impact device 3 to give an impact. An embodiment of the impact device 3 will now be described in detail with reference to FIG. As shown in the figure, the impact devices 3 are arranged side by side, for example, alternately on the left and right conveyors 6 so as to be impacted from an appropriate periphery such as a side surface of the container 1 filled with the foamable liquid, and the respective foamable liquids are arranged side by side. The container 1 filled with is subjected to an impact such that the container 1 is alternately abutted from the left and right several times to make it more easily foamed, and foamed by ultrasonic vibration in the storage tank 4 in which the ultrasonic generator 5 is installed. . This will be described in further detail. The erection member 8 that erects the left and right conveyors 6 is installed.
Further, a plurality of impact bodies 10 provided with spherical elastic impact bodies 9 made of an elastic body (for example, made of synthetic resin), which are brought into contact with the container 1 filled with the foamable liquid, are projected and fixed by being slightly shifted to the left and right. It is a thing. Further, a plurality of reciprocating devices for positively reciprocating the hitting body 9 may be provided, which are slightly shifted to the left and right. As described above, this hitting body 9
The impact is given by the action of abutting. What has been described above is the one that is brought into contact with the upper side of the container filled with the foamable liquid. The slide guide 11 supporting the container 1 filled with the foamable liquid from below is impacted on the container. It is possible to move up and down so as to add, to facilitate foaming. In addition, a guide body made of an elastic body having a concavo-convex portion is used to guide the neck of the container 1 filled with the foamable liquid so that the same effect occurs when the abutting portion is contacted. By providing them so that they are displaced from each other, the container 1 filled with the foamable liquid conveyed by the conveyor 6 is abutted against the guide body to give an impact, etc., and enters the storage tank 4 in which the ultrasonic generator 5 is installed in advance. Various designs can be used as long as they give a shock to the front or give a shock on the ultrasonic wave generator 5.

[0007]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) Since the impact can be applied from the surroundings such as the side surface of the container in advance, the liquid in the container can be sufficiently foamed even if the output of the ultrasonic generator is reduced, so that the fluctuation of foaming is reduced and the Can be foamed. (2) Therefore, it becomes easy to find a defective product. (3) The detection capability can be improved and the size of the entire apparatus can be reduced, resulting in cost reduction and efficient leak inspection.
