Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing dust from the inner surface of various cylindrical bodies such as bottles, cans, and tubes. Even if the dust is adsorbed by the action of
It is an object of the present invention to provide a dust removing device which can completely discharge dust from a cylindrical body in a short time, without damaging the opening of the cylindrical body, and which can save power.

Cylindrical bodies used as containers, etc., tend to have dust attached to their inner surfaces during the manufacturing, storage, transportation, etc. processes, and especially when the cylinder is made of synthetic resin, a large amount of dust can accumulate due to the action of static electricity. Adsorb.

These dust particles are removed by means such as blowing compressed air when filling the contents, but in the case of a bottomed cylindrical body, simply blowing compressed air will not remove the dust that has been blown away. Since there is a risk of settling again, compressed air must be continued to be ejected until the scattered dust is completely blown out of the cylindrical body, which has the disadvantage of being inefficient and increasing power costs, and as mentioned above. Dust adsorbed by static electricity can be removed only by blowing compressed air.As synthetic resin cylinders are increasingly used for various containers, it is possible to completely remove dust adsorbed by static electricity in one process. Although there is a need for a device that can be removed, no satisfactory device has yet been proposed.

By adopting the configuration described in the claims, the present invention can reliably remove dust from the inner surface of the cylindrical body, even if it is attracted by the action of static electricity, and completely transfer it to the outside of the cylindrical body in a short period of time. The present invention provides a device that can discharge the cylindrical body without causing damage to the cylindrical body.

The configuration of the illustrated embodiment will be explained below.

The main part of the device of the present invention is a pipe 2 equipped with a jet nozzle 1.
, a cap 3 through which a pipe 2 is airtightly penetrated, and a suction port 4 provided in the cap 3.

The pipe 2 has a hose 6 at one end 5 having a dust removal member.
It is connected to a compressed air source of a known static eliminator, not shown.

This type of static eliminator removes static electricity from air, places an object charged with static electricity in the air-filled atmosphere, and removes the static electricity from the object. The compressed air is supplied to the pipe 2 and is ejected from the ejection nozzle 1.

The ejection and stopping of this compressed air is controlled by a limit switch LS, as will be described later.

As shown in FIG. 1, the cap 3 that penetrates the pipe 2 is slidably and airtightly fitted onto the main body portion 7 of the pipe, which has an outer diameter slightly smaller than the outer diameter of the jet nozzle 1. When the lower surface 9 is brought into contact with the opening 11 of the cylindrical body 10 that is the object of dust removal,
It is constructed so that it can be sealed.

Therefore, the lower surface 9 may be a flat surface as shown, but may also be a convex conical surface or a concave conical surface, or a rubber sheet or the like may be attached to the lower surface 9.

An opening 12 is formed in the lower surface 9.

Further, a suction beak 14 and a suction port 4 are provided on the outer periphery of the hollow box portion 8, and the suction beak 14 and the suction port 4 are connected to a vacuum device (not shown) through a hose 13. The cap 3 is connected to the cylindrical body 1 by a lumen.
0, the internal space of the cylindrical body 10 is communicated with the vacuum device via the opening 12 and the suction port 4.

Further, a plate 16 is arranged slidably in the length direction of the pipe at a portion of the pipe 2 near the end 5 having the dust removal member 5', and a plate 17 is disposed on the upper surface of the cap 3. A coil spring 18 is interposed, and as described later, the pipe 2
moves toward the cylindrical body 10, and when the lower surface 9 of the cap 3 comes into contact with the opening 11 of the cylindrical body 10 and a pressing force is applied, the cap 3 slightly springs in response to the contact pressure. The opening 11 of the cylindrical body 10 is configured to be able to move upward and prevent excessive pressing force from acting on the edge of the opening 11 of the cylindrical body 10.

The pipe 2 is connected to a guide rod 19 fixed to the frame F.
The supporting arm 21 of the bracket I.20 is slidably fitted to the
It is supported by 22.

In addition, the bracket 20 has a swinging arm 26 that engages a roller 25 with a cam groove 24 of a grooved cam disk 23 and a connecting rod 27.
It is slid back and forth along the guide rod 19.

In the figure, reference numeral 28 indicates a connecting arm between the bracket 20 and the connecting rod 2γ, and reference numeral 29 indicates a movement gap of the connecting arm 28.
A long window opened at 30 is a holder for the cylindrical body 10.

When the cylindrical body 10 is placed directly below the jet nozzle 1 of the pipe 2, the swing arm 26 and the connecting rod 27 swing in the direction of arrow A due to the rotation of the grooved cam disk 230. , the bracket 20 moves along the guide rod 19 in the direction of the arrow, and the pipe 2 is supported on the support arms 21 and 22.
also moves in the direction of the arrow, the nozzle 1 and the cap 3 approach the cylindrical body 10, and the jet nozzle 1 moves from the opening 11 to the cylindrical body 1.
It is configured to be inserted into 0.

When the lower surface 9 of the cap 3 comes into contact with the opening 11, the movement of the cap 3 is prevented, but the pipe 2
The roller 25 is inserted into the cylindrical body 10 until the roller 25 is located at the end point X of the grooved cam 24.

When the roller 25 is positioned at the operation end point X, the actuator 30 of the limit switch LS is brought to face the area where the upper end surface 15 of the plate body 16, which behaves in the same manner as the cap 3, is located, and the actuator 30 of the limit switch LS Limit switch LS on top end surface 15
The limit switch LS is arranged so as to be set to buoN.

The limit switch LS opens the supply circuit of the compressed air that has been neutralized by the ON signal, and at the same time opens the suction circuit of the vacuum device.
The circuits are configured to close when contact with the device is broken.

Since the height of the cylindrical body 10 is slightly higher, the upper end surface 1 of the plate body 16
5 contacts the actuator 30, when the pipe 2 continues to move, the opening 11 of the cylindrical body 10 and the lower surface of the cap 3,
As the pipe 2 moves, a pressing force gradually comes to act between the pipe 2 and the cap 9, but this pressing force is absorbed and relieved by the compression of the coil spring 18 in the cap 3, as described above.

In using the apparatus of the present invention, when the cylindrical body 10 is bottomless, one end of the cylindrical body 10 is hermetically closed by the holder 30 or the like.

In addition, when the length of the cylindrical body 10 to be processed is changed, the length can be changed by incorporating a turnbuckle in the connecting rod 27, or the grooved cam disk 23 can be changed to a corresponding one. good.

Since the device of the present invention has the above-described configuration, the cylindrical body 10
When the opening 11 of the tube 10 is sealed with the cap 3 and compressed air, which has been neutralized in advance, is ejected from the jet nozzle 1 of the pipe 2 inserted into the cylindrical body 10 to the inner surface of the cylindrical body 10, the inner surface of the cylindrical body 10 is Including dust that was attracted by static electricity,
All dust is blown away from the inner surface,
Ride the ejected air current.

At the same time, the suction action of the vacuum device acts on the internal space of the cylindrical body 10 through the suction port 4 and the opening 12 of the cap 3, so the airflow containing dust is instantly sucked into the vacuum device and inside the cylindrical body. Surfaces are quickly dedusted.

As shown in the illustrated example, when the pipe 2 is operated in a constant cycle by the rotating grooved cam disk 23, etc., the supply of the cylindrical body 10,
By synchronizing the removal with the cycle, the dust removal operation can be easily automated.

Since the device of the present invention has the above-mentioned configuration and operation, even if dust etc. adhering to the inner surface of the cylindrical body is attracted by the action of static electricity, it can be reliably removed in a short time. Dust can be removed from the inner surface of the cylindrical body and the dust can be reliably discharged outside the cylindrical body without settling inside the cylindrical body, making it possible to remove dust from the inner surface of various cylindrical bodies such as bottles, cans, tubes, etc. It has the effect of being highly efficient and complete.

Moreover, the cap can move along the pipe even after its end surface comes into contact with the opening of the cylindrical body, and does not apply excessive force to the opening of the cylindrical body. This has the effect of preventing damage to the parts.

Further, only when the cap side member reaches a predetermined position, the compressed air supply circuit and the suction circuit of the vacuum device are opened by the limit switch, so that unnecessary power consumption can be reduced.
