Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing device for removing dust inside a carton body, and more particularly to removing dust inside a cylindrical carton body having a body portion before forming a bottom portion. The present invention relates to a carton dust removing device.

[0002]

2. Description of the Related Art Conventionally, it is not possible to remove dust adhering to a blank plate before forming a carton body by brushing or air blowing in a blank plate. It is being appreciated. However, there is a problem in that the dust thus removed reattaches.

Further, in a carton body containing a liquid such as milk or juice, a synthetic resin layer such as polyethylene is provided on the inner and outer walls of the container, and when forming the body of the container,
Due to heat adhesion, the dust that adheres to the inside of the container is not only mere adhesion, but also a wide variety such as static electricity adhesion and heat adhesion (for example, synthetic resin residue is melted and temporarily adhered). Is the adhered state.

Therefore, it is difficult to completely remove these various kinds of adhered dust simply by brushing or air blowing.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and more easily removes dust in a variety of adhering states inside a tubular carton body from the conventional one. It is an object to provide a device for more complete removal.

[0006]

In order to solve such a problem, the present invention has a bottomed hollow cylindrical carton body holder having a carton body receiving portion projecting outward, and one end thereof is compressed. An air blowing pipe provided with an air blowing nozzle connected to an air source, penetrating the peripheral wall of the carton body holder, and inserted horizontally toward the upper end opening, and an upper end opening of the carton body holder. The dust removing tool slidably contacting the inside of the peripheral wall of the carton body provided on the outer peripheral wall of the portion, and the air suction port connected to the air suction source provided below the peripheral wall of the holder, the carton body receiving portion, A first operation control means for starting air blowing when the carton body abuts is provided, and a second operation control means for stopping the air blowing when the carton body is separated is provided in the vicinity of the air blowing nozzle. It is obtained by a configuration in which the dynamic control means.

[0007]

According to the present invention, when the carton body is inserted into the carton body holder, when the carton body slides on the dust remover provided on the outer peripheral wall of the carton body holder, the inner wall of the carton body is squeezed. Then, dust adhering to the inner wall of the carton body is squeezed off. In this operation, the carton body contacts the dust remover,
It continues until separated.

When the carton body comes into contact with the carton body receiving portion, the first control means operates to start air blowing, and this operation is continued until the carton body drawing is completed.

[0009]

The present invention will be described in detail with reference to the drawings. Figure 1
1 is an explanatory view showing a cross section of an embodiment of the present invention, in which 1 denotes a carton body holder, and this carton body holder 1 has a bottomed and hollow rectangular cross section, At the lower part thereof, there is a carton body receiving portion 11 projecting outward.

In the carton body holder 1, an air blowing nozzle 21 is formed which penetrates between the carton body receiving portion 11 and the bottom portion of the peripheral wall and one end of which is horizontally opened at the front end which is inserted toward the upper end opening. The other end is provided with an air blowing pipe 2 which is connected to a compressed air source (not shown) for supplying compressed air.

Here, in this embodiment, the air blowing nozzle 21 is composed of an upper member 211 and a lower upper member 212, and the upper member 211 has a dome shape whose peripheral edge is inclined downward over the entire circumference. The lower member 212 is slightly smaller than the upper member 211, and has an opening at the center for connecting with the air blowing pipe 2.

Further, the upper member 211 is formed in such a size that a small gap is maintained between the peripheral edge of the upper member 211 and the carton body A when the carton body A is inserted. Upper member 2
By configuring the 12 and the lower member 212 in this way, the carton body A can be easily inserted, and
By the dust remover, the dust on the inner wall of the carton body A that has been squeezed off is reliably sucked and removed from the suction port without scattering during insertion.

Further, the carton body holder 1 is provided with an air suction port 12 between the carton body receiving portion 11 and the bottom portion of the peripheral wall. The air suction port 12 is connected to an air suction pump (not shown) by an air suction pipe.

Further, a dust remover 3 which is in contact with the inside of the peripheral wall of the carton body A is provided on the outer peripheral edge of the upper end opening of the carton holder 1. Here, as the material of the dust remover 3, a fine brush, cotton cloth, or the like can be used.

Further, one side of the carton body receiving portion 11 is provided with a plate-like body 41 rotatably provided downward to start blowing air when the lower end of the carton body comes into contact with the side.
A first actuation control means 4 consisting of a limit switch 41 with 1 is provided.

On one side of the air blowing nozzle 21, there is provided a second operation control means 5 comprising a limit switch 51 for stopping air blowing when the carton body A is separated from the carton holder 1. is there.

Next, the operation of the dust remover of the present invention will be described. First, when the cylindrical carton body A is inserted into the carton body holder 1 by using an appropriate insertion means, the inside of the peripheral wall of the carton body A gradually falls on the dust remover 3 from the bottom to the top as shown in FIG. I will contact you. At this time, the dust adhering to the inside of the peripheral wall of the carton body A is squeezed by the dust remover 3 and peeled off.

The lower end of the carton body A has a plate-like body 41.
1, the plate-like body 411 rotates downward and hits the carton body receiving portion 11 to complete the insertion of the carton body A. At this time, an electric signal is sent by the limit switch 41 to start the operation of the compressed air source and the air suction pump, and the dust inside the carton body A is blown by air and blown away, and sucked and removed.

Next, withdrawing work of the carton body A is started by an appropriate pulling means, and the carton body A is a plate-like body 41.
It is separated from the carton body receiving portion 11 in a state of being in contact with 1. Subsequently, the carton body A is separated from the plate-shaped body 411 and gradually pulled out, and air blowing and air suction are continued until the bottom of the carton body A passes by the side of the air blowing nozzle 21.

When the bottom of the carton body A passes by the side of the air blowing nozzle 21, an electric signal is sent by the limit switch 5 to stop the operation of the compressed air source and the air suction source. By repeating the intermittent operation as described above, it is possible to reliably remove the various kinds of dust attached to the inner wall of the cylindrical carton body A.

Here, the air suction work may be carried out continuously, but it may also be carried out intermittently only from the start of the insertion of the carton body A to the completion of the drawing.

[0022]

As described above, the dust removing device for a carton body of the present invention has a simple structure and is easy to manufacture, and it is easier to produce a wide variety of dusts attached to the inside of the carton body. In addition, it has an excellent effect that it can be removed more completely.
