Description

[Detailed description of the invention] The present invention relates to a dust removal device for bottle containers.

To explain a bottle container using the example of a medicinal bottle container such as a vial bottle, the boxed vial bottle is unpacked, foreign matter and dirt are removed using a bottle washer, and then it is placed in a sterile room. Sterilized and dried in a sterilized drying room,
The treated bottle container is filled with a chemical solution using a chemical solution filling machine located in a sterile room, and then capped.

Although the above steps are conventional, there are rare cases in which bottles are damaged or cracked during the cleaning and sterilization steps.

In this case, inspectors check the bottles that come out of the sterilization and drying room in groups, and if any damaged bottles such as those mentioned above are found, they check the bottles that are nearby. The broken bottles were removed and the remaining bottles were returned to the cleaning process.

The reason for this was that it was not known whether glass fragments from the broken bottle were present in the bottle container near the broken bottle, and the suspected bottle container was rewashed again to remove the glass fragments.

This work is very labor-intensive and nerve-consuming, but at the same time, it is an unstable check, and if the glass fragments from the broken bottle fly far away, the bottle containing the glass fragments will not be checked at all. May be filled with chemical liquid.

The present invention was developed in view of the above circumstances, and it only removes and discards broken or cracked bottle containers, and all other bottle containers are turned over and the interior is removed to completely remove dust. The aim is to improve safety by doing this.

To explain the details of the embodiment with reference to the drawings, in FIG. This is a turntable for alignment, and the turntable 1 aligns the bottle containers 2 in two rows and sequentially sends them toward the conveyor 3.

Then, broken bottles and cracked bottle containers are extracted from the group of bottles on this turntable 1.

The conveyor 3 and the turntable 1 are connected by two parallel rows of guide rails 4, and the bottles aligned by the turntable 1 are sequentially sent to the conveyor 3 by the respective bottle pressures.

At this time, the bottle containers 2 are counted by the counter member 5, and a constant number (15 bottles in this embodiment) of the bottle containers 2 are prevented from being sent to the carrier 3 by a signal set on the carrier 3. Further, the first bottle container 2 is prevented from advancing by a stopper 6, and the 15 bottle containers are set in two rows in contact with each other.

Reference numeral 7 denotes a carrier disposed parallel to the carrier 3 and at a predetermined interval. connected.

Two guide rods 9 are arranged parallel to each other at an appropriate distance between the two conveyors 3 and 7 so as to be perpendicular to them. Although the guide rods 9 are not particularly shown, It is fixed to the machine frame.

Between the two guide rods 9, holders 10 and 11 parallel to the carriers 3 and 7 are bridged so as to be movable left and right, and vacuum suction bodies 12 are placed above the holders io and ii, respectively.
, 13 are pivotally supported so as to be freely rotatable 180 degrees in forward and reverse directions.

A gear 14 is provided at one shaft end of each of the vacuum suction bodies 12 and 13.
, 14' and the motors i s , i s
The gears 16 and 16' are meshed with each other, and the gears 14 and 1
6, 14', and 16', the vacuum suction bodies 12 and 13 are configured to repeat 180° independently.

Further, as shown in FIG. 3, connecting rods 19 and 20 having guide elongated holes 17 and 18 in the vertical direction are attached to the lower side of the holder 10.11, and the guiding elongated holes 17 and 18 of these connecting rods 19 and 20 Pins 24 and 25 of arms 22 and 23 whose lower ends are pivotally supported on the machine frame 21 are engaged.

And between the arms 22, 23 and the machine frame there is a spring 26.
27 is elastically installed so that one holder 10 has a proximal behavior toward one of the carriers 3, and the other holder 11 has a proximal behavior toward the other carrier 7, respectively.

A roller 28.29 is pivotally supported on the side facing the carriers 3 and 7 of the two arms 22.23 which are bent.
is mounted on the machine frame 21 and is pressed against the surfaces of cams 31 and 32 connected to a motor 30 provided on the machine frame 21.

As shown in FIG. 2, the motor 30 and cams 31, 32 use a drive transmission structure consisting of sprocket wheels 33, 34, 35° 36 chains 37, 38, and the cams 31, 32 have different momentum and timing, respectively. The cam surface is different because of the difference.

Reference numerals 39 and 40 in FIG. 3 are lifting guide plates that serve as guides when the bottle containers 2 are carried into and out of the carriers 3 and 7, and the lower ends of these lifting guide plates 39 and 40 are perpendicular to the machine frame 21. The upper ends of the pivoted lifting rods 41 and 42 are fixed,
An arm 43 whose one end is horizontally pivoted to the machine frame 21 is loosely attached to the lower ends of the lifting rods 41 and 42, and a roller 44 provided at the lower part of the middle of this arm 43 is attached to the machine frame 21. It rests on a cam 45 that is pivotally supported.

Furthermore, since the lifting and lowering operations of both lifting guide plates 39 and 40 are completely opposite, the shape of the cam 45 is of course different.

Next, the vacuum adsorbers 12 and 13 will be described. Since both have completely similar structures, they will be described using the same reference numerals in FIG. 4.

Reference numeral 46 denotes a rod with a square end shape that forms the main body of the vacuum suction body 12, 13. Both end shaft portions 47, 48 of this rod are rotatably supported by the holders 10, 11, and one shaft portion 47.
As described above, the gear 14 or 14' is attached to the other shaft portion 48, and a pipe of a vacuum device (not shown) is connected to the other shaft portion 48.

The rod 46 is hollow, that is, a ventilation passage 49 is formed,
Each passage 51 of a vacuum valve 50 fixedly buried in the side surface of the rod body 46 is communicated with each of the ventilation passages 49 .

Reference numeral 52 is a rubber adsorbent attached to each X empty valve 50 and has an arcuate surface that fits the outer periphery of the body of the bottle container 2, and 53 is a valve lever that presses against the bottle container 2 to open the vacuum valve 50. Since these vacuum valves 50 are well-known ones, their detailed explanation will be omitted.

According to this embodiment, a constant number (15 bottles) of bottle containers 2
15 vacuum valves are installed to accommodate the

In the figure, reference numerals 54 and 55 are fixed guide plates facing above the carriers 3 and 7, and 56 is a jet nozzle.

Next, the operation will be described. Bottles 2 are sequentially arranged by the turntable 1, passed through the guide rail 4, and set to the conveyor 3 after being counted at a constant number by the counter member 5.

The motor 30 is driven by the constant count completion signal of the counter member 5, the cam 31 is rotated, and the holder 16 is moved in the direction of the conveyor 3 by the action of the arm 22 pulled by the spring 26. At the same time, the elevating guide plate 39 is lowered by the action of the cam 45.

When the vacuum valve 50 of the vacuum suction body 12, which is pivotally supported on the holder 10, is pressed against the side surface of the bottle container 2 by the action of the spring 26, the valve rod 53 of the vacuum valve 50 is retracted, and the passage 51 is opened. The air between the side surface and the adsorbent 52 becomes a suction vacuum state, and each bottle container 2 is adsorbed by the adsorbent 52.

The motor 15 is driven by this suction completion signal, and the gear 1
When the vacuum suction body 12 is reversely rotated by 1800 degrees in the direction of the arrow in FIG.
Foreign objects such as glass fragments inside are removed.

At the same time as this operation, the holder 10 is moved to the third position by the action of the cam 31.
The bottle container 2 is moved to the position shown by the imaginary line in the figure, and the bottle container 2 is supported under pressure between it and the vacuum valve 50 of the other vacuum suction body 13 located at the position of another imaginary line.

At this time, both cams 31 and 32 act in a direction to bring the arms 22 and 23 closer together, and the valve lever 53 of the other vacuum suction body 13 retracts and acts in the same manner as described above to suction the bottle container 2.

Then, the vacuum suction action of one of the vacuum absorbers 12 is cut off, and the bottle container 2 is transferred from one side to the other.

At this time, high pressure air is injected into the bottle container 2 from the jet nozzle 56 shown in FIG. 3 to clean the inside.

Then, one vacuum suction body 12 returns to the position shown by the solid line in FIG. 3 by the action of the cam 312, the spring 26, and the arm 22, and is ready to suction the bottle container 2 again.

The vacuum suction body 13 that received the bottle container 2 in the inverted state moves to another conveyance body 7 side, and also moves to the side of the motor 15' and the gear 16.
', 14' rotates the bottle container 2 180° to the carrier 7 side and transfers it onto the carrier 7 as shown by the imaginary line in FIG. While the two are separated and returned to their old state, this vacuum suction body 13 is reversed by 180 degrees and returns to the position shown by the imaginary line in FIG.

The lifting guide plates 39 and 40 rise as appropriate, ie, when the bottle container 2 is carried in or carried out, to prevent the bottle container 2 from falling.

Further, when the set bottle container 2 is transferred by suction, when the bottle container 2 is transferred to the carrier 7, both the carriers 3 and 7 are kept in a stopped state.

If there is a tipped bottle among the bottle containers 2 in the set state, the total bottle length will be different, so this will be detected and the stopper 6 will
is opened, and all the bottle containers 2 on the carrier 3 are discharged and collected outside.

In this embodiment, two rows of bottle containers 2 are arranged on the conveyor 3 so that the reversal and transfer action can be performed on two sides, but it is also possible to perform the reversal and transfer action on one side only, or in the case of two sides, one side is stopped and only one side is used. It is designed so that it can be used for many purposes.

As described above, according to the present invention, it is possible to completely invert the bottle container and remove dust from the inside again, and particularly in the case of vials, for example, the safety of filling chemical liquids can be significantly improved, and unlike the conventional method. Interventions such as glass shards can be completely removed, and there is no need to return cleaned bottles to the bottle washer.

Furthermore, since a vacuum adsorbent is used to invert the bottle container, the installation area is small, and a moderate mechanical shock is applied when inverting the bottle, making it even more effective in removing dust. It has excellent characteristics that can be applied to other applications.
