Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an attached foreign matter suction and removal device which is novel and has great industrial applicability.

In recent years, awareness of the need to prevent contamination of various products, including food, pharmaceuticals, and their packaging, has rapidly deepened, and the need for equipment to effectively remove dust and other foreign matter adhering to these various products has rapidly deepened. It is a well-known fact that social demands are increasing.

By the way, conventional devices of this kind have complicated mechanisms and high production costs, and it is necessary to manufacture a mechanism corresponding to each object that requires removal of foreign objects.In addition, the foreign object removal effect itself is not good. It also has the fundamental drawback that it is not sufficient.

The object of the present invention is to completely eliminate the drawbacks of such conventional devices through a new configuration.

Next, the structure of the present invention will be explained with reference to FIGS. 1 to 4, which are explanatory diagrams showing the basic structure, and FIGS. 5 and 6, which show a specific embodiment as a foreign matter removal device attached to printed paper.

Reference numeral 1 denotes a ventilation path forming plate that directly faces the surface of an object 2 from which attached foreign matter is to be removed and is separated from the surface of the object 2 by a certain length of clearance to form a ventilation path 3. When the object 2 moves horizontally (FIGS. 1 to 4), the ventilation path forming plate 1 is flat or almost planar; when the object 2 moves rotationally (FIG. 5) , Fig. 6)
It is preferable that the ventilation passage forming plate 1 is formed in the shape of an arc concentric with the rotation locus of the object 2.

In this case, the ventilation passage forming plate 1 is made movable so as to be able to adjust the clearance width a between the ventilation passage forming plate 1 and the surface of the object 2, thereby fully exhibiting the effects of the present invention, which will be described later. shall be done accordingly.

In addition, although there are no limitations on the means of transporting the object 2,
It shall be selected appropriately depending on the shape, size, material, etc.

4 is an exhaust port bored in the center of the ventilation path forming plate 1;
communicates with the exhaust port 4 on one side, and a blower (not shown) on the other side via a blower communication port 6.

), and roughly speaking, the exhaust port 4 is
It will communicate with the blower via the housing 5.

In the device of the present invention, with the above configuration, as shown in FIGS. 1 and 2, the first
If the air blowing action is performed in the upward direction of Figures and Figures 2,
The air inside the housing 5 flows in the direction of the arrow due to the exhaust action,
Along with this, a strong and rapid air flow begins in the direction of the arrow in the narrow ventilation passage 3 created on the surface of the object 2, and this air flow removes foreign matter adhering to the surface of the object 2. It acts extremely effectively as a force for peeling and suctioning away in the direction of the arrow, and as the object 2 moves in the direction of the arrow, the entire surface of one object 2 or multiple objects The suction and removal of foreign matter from the surface of No. 2 is carried out smoothly and continuously.

In the apparatus of the present invention, when the object 2 is a sheet-like object, for example, the length of the casing 5 in the axial direction is formed to be the same as the width dimension of the object 2, and the object 2 is If the object 2 is moved in a direction perpendicular to the axial direction of the object 2, suction and removal of the attached foreign matter can be effectively completed all at once as the object 2 moves, which is extremely effective.

In addition, when using such a long housing 5 in the axial direction,
It is desirable to provide a plurality of exhaust ports 4 and a plurality of blower communication ports 6 at equal intervals, and to connect the plurality of blower connection ports 6 and one blower using flexible pipes. .

In the apparatus of the present invention, a ventilation passage forming plate 1 that directly faces the surface of an object 2 and forms a ventilation passage 3 so as to form a clearance.
If the front surface of the object 2 is formed into a wave-like surface 7 as shown in FIG. A vibration effect can be produced to peel off the foreign matter adhering to the surface, and this is the reason why the adhering foreign matter peeling force or the adhering foreign matter suction removal force of the device of the present invention is dramatically increased.

Further, as shown in FIG. 3, at the exhaust port 4, a sliding member 8 made of felt or the like that slides into contact with the surface of the object 2 as the object 2 moves is held by a holder 9. If provided, the effect of removing foreign matter from the surface of the object 2 by the sliding body 8 and the foreign matter suction effect by the mechanism of the present invention described above are synergized,
It becomes extremely effective.

When the device of the present invention is used as a device for suctioning and removing foreign matter adhering to the printing paper 21, which is one of the objects 2, the printing paper 21 is rotated by a roller 10 in the printing process, as shown in FIGS. 5 and 6. In addition to the configuration, the ventilation path forming plate 1 is made of printing paper 21
The 5-axis housing is formed in the shape of a circular arc concentric with the rotation locus of the circular arc, and a ventilation passage 3 is provided between the two circular arc surfaces, thereby covering the width dimension of the printing paper 21. A plurality of blower series ports 6 and exhaust ports 4 corresponding to the blower series ports 6 are bored in the center direction, and each of the blower series ports 6 is formed of a flexible pipe (not shown).

) to one blower.

The clearance width a between the printing paper 21 that is rotated by the roller 10 and the ventilation path forming plate 1 can be adjusted using adjustment bolts 11.1 provided on both sides of the housing 5.
1, the roller 10 is rotatably mounted on a shaft by a pair of thrust bearings 12 and 12, which are vertically adjustable.
, 12, the roller 10 rotates in sliding contact with the thrust bearing 12.12, and moves up and down with the vertical movement of the thrust bearing 12. This allows the clearance width a to be freely adjusted.

As is clear from the above configuration, the effects of the present invention reside in the following points.

(a) A clearance with one side of the surface of the object 2 that requires removal of attached foreign matter is used as a ventilation passage 3, and the attached foreign matter is suctioned and removed by a strong and rapid air flow performed through the ventilation passage 3. , uniform, smooth and effective removal of adhered foreign matter is performed without any damage to the surface of the object 2, and the basic effect in this respect is great, especially when the surface of the ventilation path forming plate 1 is shaped like a wave. When the surface is set to 7, the effect is significant.

(b) Due to the configuration in which the clearance width a of the ventilation passage 3 is freely adjustable, the suction force can be adjusted freely, and this combined with the ability to adjust the air supply force of the blower, the type, shape, and property of the object 2 and attached foreign objects can be adjusted. It is possible to implement measures immediately in response to such matters.

(c) In particular, the printing paper 21 wound and rotated by the roller 10 in the printing process is cleaned by a mechanism having the ventilation path forming plate 1 formed in the shape of an arc concentric with the rotation locus of the printing paper 21. The device of the present invention is most suitable for suctioning and removing foreign matter adhering to printing paper during the printing process, and its effectiveness is great.

(d) It can be manufactured at low cost due to its relatively simple configuration;
In this respect as well, it has great industrial applicability.

(e) It can be applied to various objects in all fields, such as foods, medicines, their packaging, and sheet-like materials such as printed matter, and the economic efficiency in this respect is great.
