The cleaning rollers 3, 4, 5, and 6 rotate while their respective cleaning peripheral surfaces are in contact with the surface to be cleaned of the plate member 21. Since the cleaning peripheral surfaces of the cleaning rollers 3, 4, 5, and 6 have adhesiveness, foreign substances adhering to the surface to be cleaned of the plate member 21 can be adhered to the cleaning peripheral surface. Thereby, foreign matter is removed from the surface to be cleaned of the plate member 21. The cleaning rollers 3, 4, 5, and 6 are provided so as to be movable independently of each other in the direction in which the rotating shafts 3a, 4a, 5a, and 6a extend.

As shown in FIG. 2, transfer rollers 7, 8, and 5 are disposed above cleaning rollers 3, 4, 5, and 6, respectively.
9 and 10 are provided. The transfer rollers 7, 8,
The transfer rollers 9, 10 rotate while the transfer peripheral surfaces of the cleaning rollers 3, 4, 5, 6 are in contact with the respective cleaning peripheral surfaces.
Since the transfer peripheral surface has stronger adhesiveness than the cleaning peripheral surface, foreign matters adhering to the cleaning peripheral surface adhere to the transfer peripheral surface.
Thereby, foreign matter is removed from each of the cleaning peripheral surfaces of the cleaning rollers 3, 4, 5, and 6.

Next, referring to FIG. 3, the cleaning rollers 3, 4,
The mechanism for moving the rotation shafts 5 and 6 in the direction in which the rotation shafts 3a, 4a, 5a and 6a extend will be specifically described. As shown in FIG. 3, the surface of the cleaning rollers 3, 4, 5, 6 is provided with an adhesive rubber wrap 16 as a cleaning peripheral surface. Spiral thread grooves are provided on the inner peripheral surfaces of the cleaning rollers 3, 4, 5, and 6. A ball is inserted into this thread groove. The outer peripheral surfaces of the rotating shafts 3a, 4a, 5a, 6a of the cleaning rollers 3, 4, 5, 6 correspond to the thread grooves of the inner peripheral surfaces of the cleaning rollers 3, 4, 5, 6 so as to sandwich the ball. Screw groove is provided. That is, the cleaning rollers 3, 4, 5, 6 and the rotating shafts 3a, 4a, 5a, 6a
And three balls constitute a ball screw.

The rotating shafts 3a, 4a, 5a, 6a are
Bearings 3b, 4b, which are attached to a holder 20 provided perpendicular to the rotating shafts 3a, 4a, 5a, 6a.
5b and 6b are rotatably penetrated. Further, the rotating shafts 3a, 4a, 5a, 6a rotatably pass through bearings 3b, 4b, 5b, 6b attached to a fixed holder 17 provided in a U-shape inside the holder portion 20. . With the fixing holder 17, the cleaning rollers 3, 4,
The movement width of 5, 6 is limited to a certain range.

A power transmission mechanism 22 typified by a clutch or the like is provided at one end of the rotating shafts 3a, 4a, 5a, 6a. The rotation shaft provided on the power transmission mechanism 22 and the rotation shaft provided on the motor 14 are fixed by a coupling 15. Thereby, the rotational movement of the motor 14 is transmitted via the power transmission mechanism 22 to the rotating shafts 3a, 4
a, 5a and 6a.

During the cleaning of the plate member 21, the power transmission mechanism 22 is driven by the cleaning rollers 3, 4, 5, 6 and the rotating shafts 3a, 3b, and 3 according to the speed at which the plate member 21 is conveyed. 4a, 5a, and 6a are in a disconnected state so that they can rotate integrally. Therefore, in a state where the power transmission mechanism is connected, when the motor 14 is driven, the cleaning rollers 3, 4, 5, and 6 rotate the rotating shafts 3a, 4
a, 5a, and 6a by a mechanism (not shown) for restricting the rotational movement of the rotary shaft 3 using the operation of the ball screw.
a, 4a, 5a, and 6a can be moved back and forth in the extending direction. At this time, the movement amount of the cleaning rollers 3, 4, 5, 6 is
The amount by which the thread groove of the hole screw moves in the direction in which the rotation center axis extends by one rotation of the motor 14, that is, is determined by the setting lead of the ball screw. A linear guide mechanism 18 as a guide is attached to the upper part of the fixed holder 17. A mounting plate 19 for fixing the holder 20 is provided.

Next, referring to FIG. 4, the transfer rollers 7, 8,
A specific description will be given of a mechanism for vertically moving the members 9 and 10 in the vertical direction with respect to the transport surface of the plate member 21 of the horizontal movement mechanism 25. As shown in FIG. 4, the transfer rollers 7, 8, 9, 10 have their rotating shafts 7a, 8a, 9a, 10a rotatably penetrate the bearings 7b, 8b, 9b, 10b.
The bearings 7b, 8b, 9b, 10b are mounted on a bearing holder 24. This bearing holder 2
4 is attached to a vertical movement mechanism 23 typified by an air cylinder for raising and lowering the bearing holder 24.

According to the foreign matter removing apparatus having the above-described structure, a plurality of cleaning rollers 3, 4, 5,
6 can be moved so as to be displaced from each other in the direction in which the rotating shafts 3a, 4a, 5a, 6a extend. Thereby, a plurality of cleaning rollers 3, 4, 5, 6 whose lengths in the direction in which the rotating shafts 3a, 4a, 5a, 6a extend are smaller than the width of the surface to be cleaned, are prepared. The cleaning rollers 3, 4, 5, and 6 can be moved so as to be arranged according to the width. Therefore, even when the width of the cleaning surface of the plate-shaped member 21 is different, the cleaning rollers 3, 4, 5, 6, and 6 are adjusted in accordance with the width of each cleaning surface.
Can be moved, as shown in the prior art, the portion where the cleaning peripheral surface does not contact the surface to be cleaned, that is,
It is possible to set so that the incomplete removal region 132 does not exist.

Further, in the foreign matter removing device of the present embodiment, the cleaning peripheral surface is prevented from coming into contact with the projection 127 provided on the peripheral edge of the plate-like member 114 as shown in the prior art. The cleaning rollers 3, 4, 5, and 6 can be moved so as to avoid protrusions. Thereby, as shown in FIG. 5, even when the projection 27 is provided on the peripheral edge of the plate-shaped member 21, the cleaning peripheral surfaces of the cleaning rollers 3, 4, 5, and 6 do not ride on the projection 27. Therefore, the cleaning peripheral surfaces of the cleaning rollers 3, 4, 5, and 6 can be reliably brought into contact with the surface to be cleaned. As a result, foreign matter adhering to the surface to be cleaned of the plate-like member 21 can be completely removed regardless of the position, shape and size of the plate-like member 21.

Further, a plurality of cleaning rollers 3, 4, 5, 6
Is provided via a coupling 15 as a moving means for independently moving the rotating shafts 3a, 4a, 5a, 6a in a direction in which the rotating shafts 3a, 4a, 5a, 6a extend. 6 can be electrically driven independently of each other in the direction in which the rotation axis extends. Thereby, the plurality of cleaning rollers 3, 4, 5, 6 are adjusted to fit the width 29 of the surface to be cleaned and to avoid the protrusion 27.
Each can be easily and independently moved at the same time. Therefore, each time the position, shape, and size of the plate member 21 change, the cleaning rollers 3, 4, 5, and 6 can be easily moved.

Further, as shown in FIG. 1, the foreign matter removing apparatus according to the present embodiment has a detection device having a sensor 28 such as an area sensor or a shape recognition camera which is a detecting means for detecting the shape and size of the plate-like member 21. The mechanism 26 may be provided in the vicinity of the side of the horizontal moving mechanism 25 on the transport start end side.
If the detection mechanism 26 is provided, the width 29 of the cleaning surface of the plate-like member 21 and the widths a and b of the protrusions 27 are detected while the object to be cleaned is being conveyed as shown in FIG. be able to. Based on the detected data of the width 29 of the surface to be cleaned of the plate member 21 and the widths a and b of the protrusions 27, the moving amounts of the cleaning rollers 3, 4, 5, and 6, that is, the cleaning rollers 3 and 4 , 5 and 6 can be easily obtained. Thus, when the respective motors 14 are rotated by the required number of revolutions, as shown in FIG. 6, both ends of the cleaning peripheral surfaces of the cleaning rollers 3 and 6 coincide with both ends of the width 29 of the surface to be cleaned. ,
In addition to moving the cleaning rollers 3 and 6, the cleaning rollers 4 and 5 can be easily moved to a position where the cleaning rollers 4 and 5 have the overlapping portion 30.

After the movement of the cleaning rollers 3, 4, 5, and 6 in the rotation axis direction is completed, the transfer of the transfer rollers 7, 8, 9, and 10 is performed by using the vertical movement mechanism 23 shown in FIG. It can be driven so that the peripheral surface contacts the cleaning peripheral surfaces of the cleaning rollers 3, 4, 5, and 6, respectively. Thereby, by disconnecting the power transmission mechanism 22, the cleaning rollers 3,
When the rollers 4, 5, and 6 are driven to rotate with the conveyance of the plate member 21, the transfer rollers 7, 8, 9, and 10 are also driven to rotate. That is, as shown in FIG.
When 1 is sent in the transport direction indicated by arrow C, the cleaning rollers 3, 4, 5, and 6 rotate in the direction indicated by arrow D.
Next, by the rotation of the cleaning rollers 3, 4, 5, 6 in the direction of arrow D, the transfer rollers 7, 8, 9, 10 rotate in the direction indicated by arrow E. At this time, the cleaning rollers 3, 4,
Since the transfer rollers 5 and 6 are in contact with the transfer rollers 7, 8, 9 and 10, the movement of the rotation shafts 3a, 4a, 5a and 6a in the extending direction is restricted. Further, since the power transmission mechanism 22 is in the connected state, the cleaning rollers 3, 4, 5, 6 and the rotating shafts 3a, 4a, 5a, 6a rotate integrally.

As a result, the foreign substances 31 adhering to the surface to be cleaned of the plate-like member 21 are first removed from the cleaning rollers 3, 4, 5,
6 is adhered to the cleaning peripheral surface. Next, cleaning rollers 3, 4,
The foreign matter 31 adhering to the cleaning peripheral surfaces of the transfer rollers 5, 6 is adhered to the transfer peripheral surfaces of the transfer rollers 7, 8, 9, 10. afterwards,
By driving the vertical movement mechanism 23 again, the transfer rollers 7, 8, 9, and 10 are lifted. As a result, the transfer peripheral surfaces of the transfer rollers 7, 8, 9, 10 and the cleaning peripheral surfaces of the cleaning rollers 3, 4, 5, 6 do not come into contact with each other. In this state, the cleaning rollers 3, 4, 5,
6 can be moved in the direction in which the rotating shafts 3a, 4a, 5a, 6a extend.

Further, the foreign matter removing apparatus according to the present embodiment uses the position, shape and size data of the plate-like member 21 obtained by the detection mechanism 26 to clean the cleaning rollers 3, 4, 5 by the respective motors 14. , 6 may be provided with control means (not shown) for automatically controlling the movement amount. If such a control means is provided, the cleaning rollers 3, 4, 5, and 6 can be automatically moved using the control means. Therefore, the movement of the cleaning rollers 3, 4, 5, and 6 in accordance with the position, the shape, and the size of the plate member 21 can be calculated by a human by calculating the amount of movement of the cleaning rollers 3, 4, 5, and 6 by the human. The operation can be performed automatically without operating the moving means for moving the rollers 3, 4, 5, and 6.

Further, in the foreign matter removing apparatus according to another embodiment of the present invention, storage means (not shown) for storing data of the position, shape and size of the plate member 21 obtained by the detection mechanism 26 as registration data. ) May be provided. Further, in such a foreign matter removing apparatus of another example, the control means drives the respective motors 14 using the registration data stored in the storage means, so that the cleaning rollers 3 and 4 are removed. , 5 and 6 are automatically controlled.

According to another foreign matter removing apparatus having such a structure and mechanism, if data detected by the detecting mechanism 26 is stored in advance as registration data using the storage means, the same position can be obtained. When the plate members 21 having the same shape and the same size are to be cleaned, it is not necessary to detect the position, the shape and the size of each of the plate members 21 sequentially sent by using the detection mechanism 26. Therefore, it is possible to shorten the cleaning time when the plate members 21 having the same position, the same shape and the same size are continuously cleaned.
