Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a plastic returnable box, and more particularly to a box cleaning device suitable for cleaning a rectangular partition in the returnable box.

[0002]

2. Description of the Related Art Conventionally, a plastic box called a returnable box has been used as a box for storing and transporting beverage products. The plastic return box is charged by friction such as wind or vibration during storage or transportation, and carbon particles adhere to the return box to become dirty.

The dirt attached to the box is not only detrimental to the appearance, but also comes into contact with the boxed product at the partitioning part to stain or damage the product, so it must be washed and removed. 2. Description of the Related Art Conventionally, as a cleaning device for a returnable box, there are a cleaning device that sprays water from a large number of nozzles and a cleaning device that inserts a rotating brush into a partition.

[0004]

In the above-mentioned nozzle type cleaning apparatus, a large number of nozzles facing in various directions must be mounted in order to clean a plurality of partition walls, so that the cleaning station has multiple stages. There is a problem in that it is necessary to install a large amount of water.

In addition, since the rotating brush type cleaning device requires rotating motion in addition to vertical movement of the rotating brush,
There is a problem that the structure of the device becomes complicated and the tip of the brush does not come into contact with the corner of the partition, which makes it difficult to wash this part.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a box cleaning device having a simple structure capable of cleaning the corners of a partition with a small amount of pressurized water.

[0007]

In order to achieve the above object, a box cleaning device of the present invention is a cleaning tool for moving the inner surface of a plastic box having a rectangular partition in the axial direction of the partition. In the device for cleaning using, the cleaning tool comprises a water pipe provided in the axial direction and a water-permeable cloth bag provided at the tip of the water pipe, and the cloth bag is inserted into the partition. At this time, water is passed through the water pipe so that the cloth bag comes into contact with the wall surface of the partition.

[0008]

According to the present invention having the above-mentioned structure, when water is passed through the water pipe, the water bag is filled with the pressurized water, and the water bag expands and comes into contact with the wall surface of the partition. In this case, since the cloth bag is freely deformable, it also contacts the corners of the partition. Since the cloth bag is moved in the axial direction of the partition in this state, the cloth bag rubs the wall surface of the partition while discharging water from the surface, and the dirt attached to the partition is completely removed.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the box cleaning apparatus according to the present invention will be described below with reference to FIGS. FIG. 1 is a sectional view of the box cleaning device, and FIG. 2 is a view taken along the line II-II of FIG. 1 and 2, reference numeral 1 denotes a plastic rectangular box, and the inside of the box 1 is divided into a plurality of storage parts 3 by a rectangular partition 2.

The box cleaning apparatus comprises a plurality of cleaning tools 5, a head 11 for holding the plurality of cleaning tools 5, and an air cylinder 12 for moving the heads 11 up and down. The cleaning tool 5 includes a water pipe 6 extending in the axial direction of the partition 2 and a water-permeable cloth bag 7 provided at the tip of the water pipe 6.

Further, in the cloth bag 7, a bottom plate 8 made of a rectangular sponge fixed to the lower end of the water pipe 6 and the bottom plate 8 are provided.
An upper plate 9 made of a circular metal plate fixed to the water pipe 6 is arranged at a position slightly separated from the water pipe 6. The water pipe 6 is formed with a plurality of water passage openings 6 a at positions between the bottom plate 8 and the upper plate 9. The head 11 is a pipe 1
3 is connected to a water supply source 14, and the air cylinder 12 is connected to a compressed air source (not shown).

Next, the operation of the box cleaning device constructed as described above will be described. When pressurized water is supplied from the water supply source 14 to each water pipe 6 through the head 11 in a state where each cloth bag 7 is inserted into each storage part 3 of the box 1, each cloth bag 7 is filled with the pressurized water ejected from the opening 6a. To do. As a result, the surface of each cloth bag 7 expands in a shape following the inner surface 1a of the box 1 and the partition 2, and abuts on the wall surfaces thereof. Therefore, the cloth bag 7 also comes into contact with the corners of the partition 2 as shown in FIG.

In this state, when the air cylinder 12 is operated to move the head 11 up and down, each water pipe 6 and each cloth bag 7
Moves up and down in the axial direction of the partition 2. As a result, each cloth bag 7
Will rub the inner surface 1a of the box 1 and the wall surface of the partition 2 while draining water from the surface. Therefore, the inner surface 1a and the partition 2 of the box 1 are as if they were rubbed with a wet rag, and the dirt attached to the wall surface is completely removed.

[0014]

As described above, according to the present invention, the cloth bag is brought into contact with the wall surface of the partition of the box by supplying pressurized water to the cloth bag and inflating it, and water is discharged from the surface of the cloth bag. Can be washed. Therefore, the partition can be washed with a small amount of pressurized water, and the corners of the partition can be thoroughly washed.

Further, according to the present invention, since it is only necessary to move the cloth bag in the axial direction of the partition, the structure of the device becomes simpler than that of the cleaning device of nozzle type or rotary brush type.
