Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically cleaning bottles stored in a box.

[0002]

2. Description of the Related Art In a certain type of automatic oxygen measuring device for obtaining BOD5 (biochemical oxygen demand), which is an indicator of environmental water pollution, 24 measuring bottles are placed before and after a constant temperature culture of a sample. The box is mounted on the device and the oxygen in the bottle is measured automatically. Normally, dozens of boxes are inserted one after another for continuous measurement. After the measurement is completed, the box is taken out of the measuring instrument, several bottles are taken out by hand, the contents are discarded, and the bottles are washed one by one. Further, there is a device for automatically discarding and washing the contents of a large number of boxes with the bottles stored therein (for example, Japanese Patent Publication No. 05-1).
778350).

[0003]

In the above-mentioned hand washing of dozens of boxes containing 24 measuring bottles, the number of bottles reaches several hundred, and the bottles are taken out of the box and the contents are discarded. Thus, cleaning bottles requires considerable effort and time. In addition, expensive bottles are often damaged at that time, and economic losses cannot be ignored. In these small-scale bottle washing, there is a problem that introduction of a large-sized apparatus using a conveyor or the like is not advantageous in terms of investment efficiency and installation area.

In the present invention, when washing tens of bottles containing not more than 24 bottles or tens of bottles, such as 24 bottles used in an automatic analyzer for dissolved oxygen for determining BOD5, It is an object of the present invention to provide a small-scale washing apparatus that can easily dispose of contents and wash bottles with less labor than hand washing, and can reduce the damage to bottles and that is inexpensive.

[0005]

In the apparatus for cleaning bottles stored in a box according to the present invention, the shoulder of the bottle is fixed with a stick so that the bottle does not fall off even if the box is turned upside down. After inserting the bottle fixed storage box with holes into the rotary washing device with the contents of the bottle in it, turning the bottle upside down and discarding the contents, spraying washing water from the mouth of the bottle to wash,
The above object was achieved by a device for draining and taking out a box.

In the method of fixing the bottle to the box, the box containing the bottle may be submerged in the water tank. Therefore, the jig for fixing the bottle is a small number of parts, and the surface area is reduced so that the box is fixed to the water tank. It is necessary to lower the resistance of taking in and out and to reduce the adhesion of the cleaning liquid. Further, it must be easy to manufacture with few members in terms of cost. In addition, if necessary, the bottle must be easily removable from the box.

From this viewpoint, the method for fixing a bottle to a box according to the present invention is configured as follows. Pack multiple bottles closely in a box that is slightly higher than the height of the bottles, so that even when the box is turned upside down, the mouth of the bottle moves smoothly without touching the floor under the box.

Next, instead of holding down the shoulders of all the bottles with fixing bars, the bottles of the two rows of bottles in contact with one side wall of the box parallel to the rows of bottles and the bottles of all the following two rows of bottles are formed. The contacting shoulders are held down by a fixing rod, and the fixing rod is fixed to female boxes provided at both ends through male holes through holes in the side wall of the box. Thereby, all bottles are fixedly held in the box. The fixed rods saved about half compared to the case where all the bottle shoulders were pressed with the fixed rods. However, in the case where the total number of bottle rows is odd, in addition to the above, it is necessary to fix one of the shoulders of the bottles in an arbitrary row of bottles with a fixing bar. Fixing bars are not saved only when the bottles are in three rows. Therefore, it is desirable to use an even number of bottle rows.

In the case of a 100 m１００ bottle for BOD5, since the weight and capacity suitable for handling are 24, four rows of six bottles are put in a box, and two rows are fixed with one fixing rod for each row. Stopped to make a bottle fixed storage box. It is preferable that a bottle having a smaller capacity accommodates a larger number of bottles, and conversely, a bottle having a larger capacity is a bottle fixed storage box that accommodates a smaller number of bottles.

[0010] The securing rod must be immobile and capable of withstanding the weight of the bottle. The cross section is circular or polygonal, and hollow or solid is used. Usually, a hollow round tube is used. Its thickness depends on the length of the fixed bar,
When the length is about 300 mm, the thickness is desirably 5 to 20 mm. The method of fixing the fixing rod to the box may be any method. Provide a projection on one side, a female screw on the other, insert the projection into the hole provided in the box and fix one, and the other female screw as described above,
A method of fixing the fixing rod or the like is used.

As the material of the rod, a pipe or rod made of metal or rigid plastic is used. Although the pipe is light, the cleaning liquid may enter the inside, so that the hollow of the pipe may be sealed with an adhesive or the like inside the joining jig such as a screw to prevent the liquid from entering from both ends.

[0012] The bottle fixing storage box is provided with a hole through which the cleaning liquid escapes in order to improve the drainage of the cleaning liquid. Also, this hole has an effect of weakening the resistance of water when immersed in a thermostatic water bath with the above-mentioned bottle fixed storage box. The holes may be provided on the side, but generally only the bottom is sufficient. The shape of the hole may be any shape, but a circular shape is preferable from the processing surface. In consideration of strength, diameter 10
It suffices that several tens of circular objects having a size of from 30 mm to 30 mm are provided on the bottom surface of 200 × 300 mm. It is better to avoid the bottom of the bottle to drain the water. The material of the bottle fixing storage box is desirably made of synthetic resin from the viewpoint of processing and weight.

The rotary cleaning device for inserting the bottle fixing storage box and discarding the contents of the bottle and cleaning the bottle is configured as follows.
The washing water passes through a rotatable pipe having the center axis of the pipe as a rotation axis, and is connected to a washing water injection device fixed to a rotary washing box having the same axis as the rotation axis. The pipe rotates independently within a hollow fixed shaft fixed to the gantry, but the rotating shaft connected to the fixed shaft by a rotatable movable portion and the rotating washing box fixed thereto rotate together. The washing water spraying device having the number of spraying holes equal to the number of bottles is installed in the rotating washing box with the spraying opening facing the inside of the rotating washing box, and the rotating washing box has a hole through which each jetting water passes. I have. The rotating washing box has no backlash when the bottle fixing storage box is inserted, and further has a stopper for matching the mouth of the bottle with the injection port.

The gantry needs to have sufficient strength and structure to hold the entire apparatus. For example, a gantry may be provided at the lower end of the gantry with a pedestal extending below the rotary washing box. In addition, a drainage receiver for receiving waste liquid and washing water is installed below the rotating washing box. The rotary cleaning device is configured as described above.

The rotary cleaning device is preferably made of metal in terms of strength, but the rotary cleaning box is preferably made of reinforced synthetic resin or stainless steel because it comes into contact with the cleaning liquid.

The structure of the rotating shaft movable portion for connecting the rotating shaft to the fixed shaft may be a structure in which both are partially overlapped and rotated via a bearing or a rubber ring, or a structure in which both are provided with screws at the joint to rotate. Etc. are taken. In the latter case, there is a risk that the screw will rotate in one direction and the screw will come off, or the screw will be tightened and the screw will not rotate. It is desirable to fix and thereby prevent unidirectional rotation. The movable portion of the water supply pipe may be a rubber ring used for a rotating portion of a normal shower or the like.

It is preferable that a circular plate having a hole slightly larger than the pipe is provided inside the fixed shaft, the pipe is passed through the hole, and the pipe is rotated without swinging.

The pipe does not necessarily need to pass through the entire rotating shaft, but may be guided to the outside of the rotating shaft from the middle of the rotating shaft, and connected to the washing water spraying device through the outer surface of the rotating washing box. . In this case, the stopper can be omitted because the bottle fixing storage box can be inserted all the way into the rotary washing box.

The washing water spraying device is composed of a plurality of pipes in which circular pores for spraying washing water are vertically opened by the number of bottles. The pore size is 1 to several mm, and the pore size changes depending on the pressure of the washing water used. Water pressure 3-6kg /
In the case of cm 2, a circular hole of about 2 mm may be used. If the injection does not become conical due to the pumping of the washing water, the hole may be made conical. The shape of the hole is desirably a circle in which the jetted water is uniform.
Usually, a plurality of pipes having holes are connected in parallel so that each hole faces the mouth of the bottle.

The washing water spraying device does not necessarily need to be formed of a pipe, but may be a thin box having a pressure-resistant structure having a plurality of holes adapted to the mouth of the bottle.

Since the drainage receiver is for preventing the drainage from flowing to the floor and for reusing the washing water, it can be omitted when the drainage receiver is not required. A sink may be used. In order to reuse the washing water, the washing water after washing is returned from the drainage receiver to the washing water container for reuse.

As the drainage receiver, a cylindrical water receiving device centered on the rotating shaft of the washing device may be installed so as to be rotatable or separated at the same time as the box and not to rotate.

The stopper stops the insertion of the bottle fixing storage box at a predetermined position, and includes a protrusion, a rod,
Or, it is constituted by a surface or the like. When the above-mentioned pipe passes outside the rotary washing box, the inner wall may be used as a stopper.

In order to wash the bottle, the rotary washing device is stopped at a position where the injection device of the rotary washing box is at the top, and the bottle fixing storage box containing the contents to be discarded in the bottle is turned upward by the stopper into the rotary washing box. Insert until it stops, and align the mouth of the bottle with the injection hole. Next, when the rotary washing box is rotated by 180 degrees, the contents flow out and are discharged through a drainage receiver. Next, predetermined washing water,
For example, after a soap solution is pressure-fed and the inside of the bottle is spray-washed, the water supply is stopped and left for a while to drip and drain the water. Next, the same operation is performed with tap water to remove the attached soap solution. Next, the same operation is performed using another kind of cleaning liquid, for example, an alkaline liquid and tap water. This operation can be repeated for the required number of cleaning liquids. When the washing with the predetermined washing water is completed and the last washing with water is completed, the bottle fixing storage box is taken out upside down.
If the rotary washing box is rotated 180 degrees with the bottle-fixed storage box inserted, water droplets from the injection port enter the bottle and hinder drainage. Therefore, it is preferable to remove the bottle-fixed storage box upside down. In many cases, the bottle is dried upside down, so it is better to take out the bottle upside down. If the washing is only water washing, the washing ends with water washing. After washing with tap water, it can be washed with ion-exchanged water.

When the bottle containing no contents is to be washed, the above operation is performed while the rotary washing device is fixed at a position where the injection device of the rotary washing box is located below.

When a plurality of washing waters are used in one washing machine, in order to use each washing water in a circulating manner, a switching cock is attached to a tip of a drain port of a drainage receiver, and each washing water is manually or automatically operated. Switch back to the wash water container. Further, it is also possible to sequentially move the bottle-fixed storage boxes to a dedicated cleaning device for each of the cleaning liquids for cleaning.

If the washing is performed with warm water, the bottle can be dried quickly. Since gas can be used instead of water, the bottle can be dried quickly by sending heated air after washing with water.
