Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bottle washing device that utilizes ultrasonic waves and pays special attention to cleaning the openings.

In bottles such as beer bottles, when the bottle is returned with a crown after consuming the contents of beer etc., the iron content in the crown is leached out and rust adheres to the widened part. Conventional washing methods have the disadvantage that they are difficult to remove, so attempts have been made to attach an ultrasonic oscillator to the washing liquid tank of a bottle washing machine and use the washing machine that generates vibrations to wash the bottles. However, the plane (acoustic) waves oscillated by the ultrasonic oscillator are diffused and transmitted not only to the bottles to be washed, but also to the entire tank, and the energy is wasted for purposes other than washing the bottles, so its utilization efficiency is extremely low. In addition to the drawbacks of
Since the ultrasonic waves used for cleaning the bottle are not particularly concentrated on the widened area, the heavily contaminated widened area cannot be sufficiently cleaned, and a uniform cleaning effect on the entire bottle cannot be obtained.

In view of the current situation, the present invention is designed to clean the bottle by reflecting the ultrasonic waves diffused to areas other than the heavily soiled enlarged area at the gas interface of the measurement box-shaped reflective surface forming member that stores gas. The purpose of the present invention is to provide an ultrasonic cleaning device that improves the cleaning effect by uniformly cleaning the entire bottle by concentrating the cleaning on the thickened part of the bottle that is particularly contaminated. This will be explained based on examples.

FIG. 1 schematically shows a bottle washing machine 1, in which bottles to be washed are first supplied to a bottle supply section 2 by a conveyor device, etc., and then passed through a basket carrier chain drive sprocket 3.
basket carrier chain driven by 4
While the cleaning liquid 6 of the soaking bottle tank 5 is supplied to a basket attached to the bottle and moves up and down according to the plurality of upper floating sprockets 7 and lower floating sprockets 8, the dirt on the bottle is expanded and softened, peeled off, and then finished. The bottle is sent to the washing section 9, is finished washed with high-pressure water, etc., and is sent to the discharge bottle section 10.
Cleaning is complete.

In order to increase the cleaning effect in such work, an ultrasonic oscillator 11 is provided at the bottom of the cleaning liquid 6 in the immersion bottle tank 5, as shown schematically in FIG. 2, to irradiate the cleaning liquid 6 with ultrasonic waves. , the baskets 12 attached to the basket carrier chain 4 are arranged side by side to enhance the cleaning effect of the bottles 13 inserted in an inverted state, and are located at a position where the progress of dipping of the bottles 13 is not hindered, that is, between each of the bottles 13. A narrow box-shaped reflective surface forming member 15 in which gas 14 is stored.
The gas 1 in the box-shaped reflective surface forming member 15 is provided to absorb the energy of the ultrasonic waves diffused in directions other than the bottle, especially in the widening part.
The water is reflected at the interface 16 between the cleaning liquid 6 and the cleaning liquid 6, and is concentrated on the seed opening of the bottle 13, where dirt is particularly high, thereby further improving the cleaning effect.

Note that 17 is a lower floating sprocket shaft.

In FIGS. 3 to 6 showing the essential parts of the bottom of the soaking bottle tank 5, reference numeral 11 denotes an ultrasonic oscillator equipped with an ultrasonic diaphragm 18 on the top surface, and a support having an angular cross section. It is attached via a member 19 to the side surface of a column 20 having an angular cross-section, and the column 20 is further attached to the bottom plate 22 of the soaking bottle tank 5 via a base plate 21.

Reference numeral 15 denotes a member for forming a thin box-shaped reflective surface, which is disposed above the ultrasonic diaphragm 18 and between the bottles so as not to impede the progress of immersion of the bottles 13. Support members 23 and 24 A bottle guide 25 is provided on the entry side of the bottle 13 to ensure safe advancement of the bottle 13.

Furthermore, gas such as air supplied from a compressed gas generator 26 through a gas reservoir 27, a gas supply main pipe 28, and a gas supply branch pipe 29 is stored in the measuring box-shaped reflective surface forming member 15. The supply pressure of the gas is adjusted by the gas pressure adjusting device 30 according to the liquid depth of the liquid surface at the interface formed between the gas and the cleaning liquid in the measuring box-shaped reflective surface forming member 15.

Ultrasonic waves emitted from the ultrasonic vibrator of the ultrasonic oscillator 11 are irradiated onto the cleaning liquid 6 via the ultrasonic diaphragm 18 .

The energy of the ultrasonic waves irradiated to the cleaning liquid 6 is diffused into the cleaning liquid, but by arranging the measurement box-shaped reflective surface forming member 15 that stores the gas 14, the energy of the ultrasonic waves irradiated to the cleaning liquid 6 is dispersed. It is reflected at the interface and concentrated on the seed opening of the bottle 13, which is particularly contaminated.

Ultrasonic energy is reflected even on the iron plate tank wall, but in particular at the interface with a gas layer such as air, almost 100% is reflected.
Its cleaning power can be effectively utilized.

Placing the measuring box-shaped reflective surface forming member 15 near the mouth of the bottle 13 to be cleaned is particularly effective for cleaning rust that occurs at the seed opening, and for this reason, uniform cleaning of the entire bottle can be achieved. Effective in improving effectiveness.

As is clear from the above description, the bottle cleaning device using ultrasonic waves according to the present invention is provided with an ultrasonic oscillator that oscillates upwardly ultrasonic waves at the bottom of the bottle soaking tank, and the ultrasonic waves oscillated from the ultrasonic oscillator are used to wash bottles. In order to reflect the ultrasonic waves diffused to areas other than the target bottle at the interface between the cleaning liquid and the gas, a measurement box-shaped reflective surface forming member containing gas inside is installed at a position that does not impede the progress of immersion of the bottle. Since a device for supplying gas inside the box-shaped reflective surface forming member is installed, the ultrasonic waves that have diffused to areas other than the particularly heavily contaminated widened areas are absorbed by the gas interface stored inside the measuring box-shaped reflective surface forming member. By reflecting the ultrasonic waves, it is possible to increase the efficiency of using the ultrasonic waves and strengthen the vibration force at the seed opening, which is particularly contaminated, thereby improving the cleaning effect by uniformly cleaning the entire bottle. .
