Specifically, in the molded glass bottle, carbon marks or stains are often left in the vicinity of the bottle inlet, which is removed by a cleaning operation.

Conventional cleaning work has been carried out by using a cleaning liquid containing a chemical component, taking the glass bottle into the cleaning liquid and then taking it out. However, since the removal efficiency is low even after cleaning, there is still a problem that carbon marks remain after cleaning. In addition, there is a problem that the yield of the production is lowered due to the long cleaning time. In addition, a part of the cleaning solution remains in the glass bottle after the cleaning, thereby causing a problem of producing a defective bottle.

Also, the conventional cleaning apparatus was limited to a glass bottle of a certain size depending on the diameter of the lower end of the glass bottle. However, glass bottles are produced in various bottle shapes and sizes depending on the application. That is, since the conventional cleaning apparatus can only be limited to a few glass bottles, there is a problem that the operation rate is low.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic view of an ultrasonic cleaning apparatus according to an embodiment of the present invention, and FIG. 2 is a side view illustrating a side portion of FIG. 1, the ultrasonic cleaning apparatus includes a rail part 10, a belt part 20, a driving part (not shown), a grip part 30, a cleaning part 40, an ultrasonic wave generating unit 50, and a drying unit 60 ).

The rail portion 10 can be arranged to have a predetermined conveying path by a pair of opposed frames. However, the rail portion 10 is preferably formed to have an upper layer and a lower layer. According to a preferred embodiment of the present invention, an empty bottle is introduced for cleaning operation at either side of the upper layer. On the other hand, the cleaning operation is carried out in a state where empty bottles are upside down in the lower layer.

The frames constituting the upper layer and the lower layer of the rail part 10 may be arranged so as to include not only the straight section but also the curved section. However, the arrangement shape can be changed according to the place of arrangement. On the other hand, the portion connecting the upper layer and the lower layer is preferably formed as a curved section having a certain radius. So that empty bottles can be smoothly moved between the layers.

Further, the rail portion 10 can be formed using a metal or a rigid plastic material. However, it is preferable that it is excellent in corrosion resistance and the like.

The belt portion 20 can be coupled to each of the inner sides of the frame and can move along the rail portion 10. Specifically, a rail groove (not shown) may be formed on the inner surface of the frame. This provides an engaging space to which the belt portion 20 can engage. In addition, the rail groove serves as a guide so that the coupled belt portion 20 can move along the rail portion 10. [ At this time, the rail grooves are formed continuously along each frame. As a result, the belt portion 20 can circulate and move along the rail portion 10.

Also, referring to FIG. 2, the belt portions 20 may be configured as a pair. That is, they can be coupled and formed corresponding to the rail grooves of the respective frames. At this time, the belt portion 20 may be formed as a continuous single member, but the single unit members may be connected to each other to be continuous.

A bearing (not shown) or the like capable of reducing a running resistance may be further formed on the belt portion 20 coupled to the rail groove. As a result, the energy for driving the belt portion 20 can be reduced.

The belt portions 20 are formed as a pair facing each other, and a width having a predetermined distance may be formed between the belt portions 20. However, the width formed between the belt portions 20 can be variably adjusted. For example, the belt portions 20 can be gradually deformed so as to be close to each other or away from each other, so that the width can be adjusted. At this time, a sliding method or the like can be used.

The driving unit can drive the belt unit 20. [ For example, the driving unit may drive the belt unit 20 by providing rotational force to a pulley or the like coupled to the belt unit 20.

The grip portion 30 is preferably provided to face the belt portion 20 in the vertical direction. As a result, the belt portion 20 can grip the empty bottle more stably. At this time, the empty bottles can be fixed between the grip portions 30 and the belt portion 20.

Therefore, it is preferable that the grip portion 30 is formed of an elastic body having a high frictional force. For example, natural or synthetic rubber may be used. This is because it can provide a high frictional force when in contact with an empty glass bottle. Further, the grip force can be further improved by the elastic force.

3 is a perspective view showing the grip projection of FIG. Referring to FIG. 3, the grip portion 30 may be formed of a plurality of grip protrusions 32. It is preferable that the grip projection 32 is provided continuously to the belt portion 20.

As described above, the empty bottles are introduced into the ultrasonic cleaning apparatus, which is an embodiment of the present invention, by a conveyor or the like that is automatically transported. At this time, since the empty bottles flow in close contact with each other, it is preferable that the grip protrusions 32 are continuously provided in order to effectively grip the empty bottles.

On the other hand, the grip projection 32 may include a fixed end 34, a projection 36, and a groove. Here, the fixed end 34 refers to the lower end of the grip projection 32 that is fixed to the belt portion 20. [ The protruding portion 36 is a portion formed by extending from the fixed end 34, and is a portion that contacts the empty bottle and grips the empty bottle. At this time, the protrusion 36 may further include a hole 38 passing through the protrusion 36. The hole 38 allows the projection 36 to be further deformed when gripping an empty bottle larger than the width between the grip portions 30. [

The empty bottles are moved from the upper layer to the lower layer along the rail portion 10 while being gripped by the grip portion 30. [ In the process of moving to the lower layer, the empty bottle is turned upside down. That is, the empty bottles are reversed so that the entrance faces downward. In this state, the empty bottle is moved to the cleaning part 40 disposed under the lower part of the rail part 10.

The cleaning portion 40 includes a container for containing the cleaning liquid therein. At this time, water can be used as the washing liquid. That is, it is eco-friendly because it can be cleaned using water. However, other cleaning liquids other than water may be used. Also, since empty bottles are mainly used to store liquids, washing with water may be more stable.

On the other hand, it is preferable that the container constituting the cleaning part 40 is formed so as to coincide with the arrangement direction of the frame disposed on the lower layer of the rail part 10. [ It is preferable that the container is disposed within a certain distance from the lower layer. This is because the empty bottles in a reversed state must move along the frame that constitutes the lower layer with its mouths partially locked in the wash liquid. For example, the width of the container can be formed within about 200 mm. This takes into account the size of all empty glass bottles.

As described above, it can be washed using water. This is due to at least one or more ultrasonic generating units 50 disposed in the cleaning unit 40. Fig. 4 is a bottom view of the washing section of Fig. 1; Fig. Referring to FIG. 4, it is preferable that a plurality of ultrasonic wave generating units 50 are disposed on the bottom surface and both sides of the container constituting the cleaning unit 40 in the moving direction of the belt unit 20. In particular, the ultrasonic wave generating unit 50 is disposed on the outer surface of the container. This is because the ultrasonic waves can be transmitted to the empty bottles through the bottom surface and both sides constituting the container and then the cleaning liquid as a medium.

That is, the preferred embodiment of the present invention introduces an ultrasonic cleaning method and allows quick cleaning while using water. Specifically, the cleaning time can be within 10 seconds. In this case, the temperature of the water is preferably set within a range of 40 to 50 degrees. At this time, the intensity of the ultrasonic wave can be set differently depending on the distance from the empty bottle.

The drying unit 60 is disposed above one end of the washing unit 40 and injects air toward the inlet of the empty bottle that has been cleaned. At least one drying unit 60 may be disposed. For example, the drying unit 60 may be an air blower device that blows air.

Specifically, the drying unit 60 can be disposed close to the inlet of the empty bottle to remove water (moisture) remaining in the empty bottle. To this end, the drying unit 60 may be arranged in multiple stages. For example, at least one or more drying units 60 may be installed at each of a position near the empty bottle and a location far from the empty bottle. As a result, it is possible to reduce defective products due to moisture remaining in empty bottles.

5 is an enlarged view of a portion A in Fig. Referring to FIG. 5, a step 12 bent at an end may be formed at one end of a frame constituting a lower layer of the rail part 10 to reduce defective products due to moisture.

Specifically, the step 12 is a shape that is not gently inclined but is bent to form a peak. As a result, temporary bottlenecks occur in empty bottles passing through the steps 12. As a result, the water remaining in the empty bottle can be physically removed. As such, the moisture remaining in the empty bottle can be effectively and completely removed by the step unit 12 formed at one end of the frame and the drying unit 60.

Hereinafter, a cleaning method of an ultrasonic cleaning apparatus according to an embodiment of the present invention will be described. 6 is a flowchart illustrating a cleaning method of an ultrasonic cleaning apparatus according to an embodiment of the present invention. Referring to FIG. 6, the cleaning method according to the preferred embodiment includes a gripping step s10, an opposing step s20, a cleaning step s30, a drying step s40 and an outflow step s50 do.

First, the gripping step s10 is a step of gripping the lower end portion of the empty bottle introduced into one side of the upper layer of the rail portion 10. At this time, the width of the belt portion 20 coupled to the rail portion 10 can be variably controlled according to the size of the lower end portion of the empty bottle. This is possible by automatic or manual operation.

In the next step s20, the gripped empty bottle is transferred from the upper layer to the lower layer along the rail part 10, and the empty bottle is inverted so that the inlet of the empty bottle faces downward. In other words, it reverses its position to flush the empty bottle inlet. At this time, the empty bottles are fixed to the grip portion 30 and are not separated from the belt portion 20.

Next, the cleaning step (s30) is a step of transferring the empty bottle in a state in which a certain portion including the entrance of the empty bottle is immersed in the cleaning solution, and providing ultrasonic waves for cleaning. At this time, the ultrasonic waves can be continuously supplied to the empty bottles by the ultrasonic wave generating unit 50 arranged in correspondence with the conveying direction of the empty bottles on the bottom surface and both sides of the washing unit 40 containing the washing liquid.

When the ultrasonic wave generating unit 50 is used, it can be cleaned using water. That is, the inlet portion of the empty bottle is transported while being immersed in water, and foreign substances such as carbon are removed by ultrasonic waves.

Then, the step of drying (s40) is a step of drying to remove water, which is a cleaning liquid, in the empty bottle. If water remains inside the empty bottle, the empty bottle is judged to be defective. Therefore, it is preferable to remove the water remaining in the empty bottle after the step of drying (s40).

To this end, the step 12 may be provided at one end of the lower layer frame of the rail part 10 to provide a temporary wobble to the empty bottle passing through this part. As a result, the water remaining in the empty bottle can be discharged to the outside. In addition, water can be removed by injecting air toward the empty bottle inlet. At this time, for example, an air blur apparatus or the like can be used.

And, the outflowing step s50 is a step of delivering the dry empty bottle to the upper layer, and discharging the empty bottle out of the lower part 10. Specifically, the empty bottle is conveyed to the upper layer through the drying step (s40), where the empty bottle is placed in a standing state. The empty bottle is discharged to the outside of the ultrasonic cleaning device while being transported along the rail part 10 by the belt part 20. [

That is, according to the preferred cleaning method of the present invention, foreign matter such as carbon can be cleaned by ultrasonic waves in a water-immersed state in a state where the empty bottle is in a collapsed state. In addition, the empty bottle can be gripped by the belt portion 20 regardless of the size of the lower end portion, thereby increasing the operating rate of the ultrasonic cleaning device.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
