Description

The present invention relates to a technique for removing deposits attached to a sheet-like material having a pair of sheet surfaces.
More specifically, the roller having adhesiveness is rotationally driven in contact with the sheet surface of the sheet-like material, and the adhered matter adhering to the sheet-like material having a pair of sheet surfaces is transferred to the outer peripheral surface of the roller. It is related with the technique removed by this.

  Conventionally, for example, (A) a method using a brush, (B) a method using a blade-like member, as a method for removing deposits attached to a pair of sheet surfaces of a sheet-like article such as paper, a resin film, or a cloth. (C) a method using an adhesive tape, (D) a method using an adhesive roller, and the like are known.

(A) The method using a brush is a sheet-like material, more specifically, a sheet-like material by contacting the brush with a pair of sheet surfaces conveyed in a direction parallel to the pair of sheet surfaces. In this method, the adhering matter adhering to the pair of sheet surfaces is adhered to the hair of the brush and removed from the pair of sheet surfaces. For example, as described in Patent Document 1.
However, in the method using the brush (A), since the brush hair itself that has fallen off from the brush can become an adhering substance, there is a demand for removing the adhering substance, for example, when a sheet-like object is a raw material of a container that contains food. In severe cases, there is a problem that the management of the brush becomes complicated.

(B) A method using a blade-like member is a sheet-like material, more specifically, by bringing a blade-like member into contact with a pair of sheet surfaces of a sheet-like material conveyed in a direction parallel to the pair of sheet surfaces. Is a method of scraping off the adhering matter adhering to the pair of sheet surfaces of the sheet-like material and removing from the pair of sheet surfaces. For example, as described in Patent Document 2.
However, the method using the (B) blade-like member may cause wrinkles extending in the conveying direction on the pair of sheet surfaces of the sheet-like material depending on the material of the sheet-like material. When the aesthetic appearance of the sheet surface is regarded as important, or when a thin surface treatment layer is formed on a pair of sheet surfaces of the sheet-like material, there is a problem that it cannot be applied.

(C) The method using the adhesive tape is to press the adhesive tape (tape having adhesiveness on one surface) onto the sheet surface of the sheet-like material conveyed in a direction parallel to the pair of sheet surfaces. Thus, the sheet-like material, more specifically, the adhering material adhering to the pair of sheet surfaces of the sheet-like material is adhered to the adhesive tape and removed from the pair of sheet surfaces. For example, as described in Patent Document 3.
However, the method using an adhesive tape is expensive because the adhesive tape is a consumable item, and the length of the adhesive tape is finite. There is a problem that the conveyance of the sheet-like material must be stopped.

  (D) A method using an adhesive roller is a sheet-like material, more specifically a sheet-like material, by contacting the adhesive roller against a pair of sheet surfaces of a sheet-like material conveyed in a direction parallel to the pair of sheet surfaces. In this method, the adhering matter adhering to the pair of sheet surfaces is adhered to the outer peripheral surface of the adhesive roller and removed from the pair of sheet surfaces. For example, it is as described in Patent Document 4 to Patent Document 8.

The method described in Patent Document 4 is to remove foreign matter attached to the surface of the polyimide film by bringing an adhesive roller having a predetermined rubber hardness into contact with the polyimide film.
However, the method described in Patent Document 4 does not disclose how the polyimide film is conveyed and how the adhesive roller is arranged with respect to the polyimide film.

In the method described in Patent Document 5, dust attached to the surface of the printed circuit board is removed by rotationally driving a pair of upper and lower adhesive rollers that sandwich the printed circuit board.
However, the method described in Patent Document 5 is effective for a sheet-like material that has a high strength and hardly bends like a printed circuit board. For example, a thin resin film, cardboard, etc. When applied to a sheet-like material made of a material that can be bent (a material that can bend elastically), the end of the sheet-like material, more strictly, the foremost part in the transport direction is one of a pair of upper and lower adhesive rollers There is a problem that the roller may wind around the roller while sticking.
As a method for solving the above problem, a method of appropriately setting the adhesive force of the adhesive roller and a method of appropriately setting the size of the gap between the pair of adhesive rollers can be considered.
However, since the adhesive force of the adhesive roller varies depending on the amount of deposits adhering to the adhesive roller, etc., the maintenance management of the adhesive force of the adhesive roller becomes complicated when the appropriate range of the adhesive force of the adhesive roller is narrow. This is not preferable for practical use.
In general, the fluctuation amount of the adhesive force generated between the adhesive roller and the sheet-like material is large with respect to the fluctuation amount of the gap between the pair of adhesive rollers, and most of the adhesive rollers are made of rubber having low hardness, Since the outer peripheral surface can wear with use and its diameter can vary, it is practically difficult to maintain and manage the size of the gap between the pair of adhesive rollers within an appropriate range.

The method described in Patent Document 6 removes dust adhering to the surface of the blank plate by rotating a pair of upper and lower adhesive rollers that sandwich the blank plate.
However, the method described in Patent Document 6 does not disclose the material constituting the blank plate, and does not mention that the blank plate can be wound around the adhesive roller depending on the material of the blank plate.

In the method described in Patent Document 7, a long fiber sheet is sandwiched between a driving roller and an adhesive roller, and the foreign matter attached to the surface of the long fiber sheet is removed by rotationally driving the driving roller. It is.
However, the method described in Patent Document 7 is intended for a long fiber sheet, and is based on the premise that there is no need to consider that the long fiber sheet winds around the adhesive roller. No disclosure has been made regarding the winding of the sheet-like material.

The method described in Patent Document 8 discloses an apparatus provided with two adhesive rubber rollers as a contact-type dust removing apparatus that removes dust adhering to a web or sheet being conveyed by contacting the web or sheet. The two adhesive rubber rollers are arranged at positions where one is separated from the other in the web or sheet conveyance path.
However, in the method described in Patent Document 8, two adhesive rubber rollers are largely separated from each other, and it is substantially impossible to sandwich a web or a sheet by these two adhesive rubber rollers. That is, the method described in Patent Document 8 is based on the premise that the target web or sheet is a long object.

As shown in FIGS. 3 and 4, the sheet 10 conveyed in the conveying direction by the upstream conveying device 120 is delivered to the adhesive roller unit 141A.
The sheet 10 is sandwiched between the first adhesive roller 142 and the second adhesive roller 144 in the adhesive roller unit 141A, and the upper surface (first sheet surface) of the sheet 10 is the first adhesive roller 142 in the adhesive roller unit 141A. The lower surface (second sheet surface) of the sheet 10 is in contact with the outer peripheral surface of the second adhesive roller 144 in the adhesive roller unit 141A.

The upper surface (first sheet surface) of the sheet 10 is in contact with the outer peripheral surface of the first adhesive roller 142 in the adhesive roller unit 141A, and the lower surface (second sheet surface) of the sheet 10 is the second adhesive roller 144 in the adhesive roller unit 141A. In the state of contact with the outer peripheral surface, frictional force (between the upper surface of the sheet 10 and the first adhesive roller 142 in the adhesive roller unit 141A and between the lower surface of the sheet 10 and the second adhesive roller 144 in the adhesive roller unit 141A ( Alternatively, the sheet 10 is conveyed in the conveying direction as the first adhesive roller 142 in the adhesive roller unit 141A and the first adhesive roller 142 in the adhesive roller unit 141A rotate.
At this time, the adhering matter adhering to the portion of the upper surface of the sheet 10 in contact with the outer peripheral surface of the first adhesive roller 142 in the adhesive roller unit 141A is transferred to the outer peripheral surface of the first adhesive roller 142 in the adhesive roller unit 141A. (Attached to the outer peripheral surface of the first adhesive roller 142), the adhering material adhering to the portion of the lower surface of the sheet 10 in contact with the outer peripheral surface of the second adhesive roller 144 in the adhesive roller unit 141A is the adhesive roller unit. It is transferred to the outer peripheral surface of the second adhesive roller 144 in 141A (becomes attached to the outer peripheral surface of the second adhesive roller 144).

The sheet 10 delivered to the adhesive roller unit 141A is sequentially delivered to the adhesive roller unit 141B, the adhesive roller unit 141C, and the adhesive roller unit 141D.
The adhering matter adhering to the upper surface and the lower surface of the sheet 10 is transferred to the first adhesive roller 142 and the second adhesive roller 144 in the adhesive roller unit 141B, and the first adhesive roller 142 and the second adhesive roller in the adhesive roller unit 141C. It is transferred to the roller 144 and transferred to the first adhesive roller 142 and the second adhesive roller 144 in the adhesive roller unit 141D.

In the following, the second adhesive roller 144 in the adhesive roller unit 141A, the adhesive roller unit 141B, the adhesive roller unit 141C, and the adhesive roller unit 141D is offset from the first adhesive roller 142 by a predetermined offset amount in the transport direction. The technical significance of the arrangement will be described.
In the description of the technical significance, whether the pair of first adhesive roller 142 and second adhesive roller 144 belongs to the adhesive roller unit 141A, the adhesive roller unit 141B, the adhesive roller unit 141C, or the adhesive roller unit 141D. Since the point is not important, this point will be described without being specified.

Temporarily, the 2nd adhesive roller 144 is arrange | positioned without being offset in the conveyance direction at all with respect to the 1st adhesive roller 142, and the clearance gap between the 1st adhesive roller 142 and the 2nd adhesive roller 144 is smaller than the thickness of the sheet | seat 10. In this case, the first adhesive roller 142 and the second adhesive roller 144 are brought into contact with the upper surface and the lower surface of the sheet 10 while being elastically deformed, respectively.
As a result, the first adhesive roller 142 and the second adhesive roller 144 are in strong contact with the upper surface and the lower surface of the sheet 10, respectively, and the sheet 10 is firmly adhered to the first adhesive roller 142 or the second adhesive roller 144 and wound. There is a case.

  Further, it is assumed that the second adhesive roller 144 is arranged without being offset in the transport direction with respect to the first adhesive roller 142, and the gap between the first adhesive roller 142 and the second adhesive roller 144 is larger than the thickness of the sheet 10. Is larger, either the first adhesive roller 142 or the second adhesive roller 144 does not come into contact with the sheet 10, and the deposits attached to the sheet 10 cannot be effectively removed from the sheet 10.

As described above, if the second adhesive roller 144 is arranged without being offset in the conveying direction with respect to the first adhesive roller 142, the first adhesive roller 142 and the second adhesive roller 142 are arranged according to the thickness of the sheet 10. It is necessary to adjust the gap with the adhesive roller 144 with high accuracy so that the force with which the first adhesive roller 142 and the second adhesive roller 144 abut on the sheet 10 (stress acting on the abutting portion) falls within a desired range. There is.
However, in reality, due to problems such as the dimensional accuracy of the first adhesive roller 142 and the second adhesive roller 144 or the dimensional accuracy of the portion that pivotally supports the first adhesive roller 142 and the second adhesive roller 144, the first It is difficult to accurately adjust the gap between the first adhesive roller 142 and the second adhesive roller 144 within a desired range.
Moreover, since the first adhesive roller 142 and the second adhesive roller 144 are made of rubber having a relatively small hardness, the first adhesive roller 142 and the second adhesive roller 144 are worn with use, and their diameters vary. Therefore, in order to keep the gap between the first adhesive roller 142 and the second adhesive roller 144 constant, the first adhesive roller 142 and the second adhesive roller 142 and the second adhesive roller 142 according to the progress of wear of the first adhesive roller 142 and the second adhesive roller 144. The gap between the adhesive roller 144 and the adhesive roller 144 must be adjusted frequently, and there is a problem that the labor is large (the operation is complicated).

In the present embodiment, the second adhesive roller 144 is disposed with a predetermined offset amount with respect to the first adhesive roller 142, so that the sheet 10 is connected to the first adhesive roller 142 and the second adhesive roller 144. When sandwiched between the sheets, the sheet 10 comes into contact with the first adhesive roller 142 and the second adhesive roller 144 by its own elastic force (force that the curved sheet 10 tries to return to a flat plate shape).
Therefore, the force with which the first adhesive roller 142 and the second adhesive roller 144 abut on the sheet 10 is such that the first adhesive roller 142 and the second adhesive roller 144 are elastically deformed (the second adhesive roller 144 is the first adhesive roller 142). The first adhesive roller 142 and the second adhesive roller 144 abut with a desired force weaker than that of the sheet 10 when the gap between the first adhesive roller 142 and the second adhesive roller 144 is smaller than the thickness of the sheet 10.
As a result, it is possible to prevent the sheet 10 from being wound around the first adhesive roller 142 or the second adhesive roller 144.
In order for the sheet 10 to contact the first adhesive roller 142 and the second adhesive roller 144 with its own elastic force (force that the curved sheet 10 tries to return to a flat plate shape), The gap between the first adhesive roller 142 and the second adhesive roller 144 is equal to or less than the thickness of the sheet 10 (the end of the outer peripheral surface of the first adhesive roller 142 and the outer peripheral surface of the second adhesive roller 144 when viewed from the conveying direction). (Including the case where the end portion overlaps). Here, the “gap between the first adhesive roller 142 and the second adhesive roller 144 viewed from the transport direction” is the end of the outer peripheral surface of the first adhesive roller 142 and the second adhesive roller 144 viewed from the transport direction. This is the distance between the outer peripheral surface and the “gap at the narrowest position between the outer peripheral surface of the first adhesive roller 142 and the outer peripheral surface of the second adhesive roller 144”.

Further, when the second adhesive roller 144 is disposed with a predetermined offset amount in the transport direction with respect to the first adhesive roller 142, the first adhesive roller 142 and the second adhesive roller 144 are worn and these The force with which the first adhesive roller 142 and the second adhesive roller 144 abut on the sheet 10 does not vary greatly even if the diameter of the roller slightly varies.
Accordingly, the first adhesive roller 142 and the second adhesive roller 144 and the second adhesive roller 144 can be adjusted without frequently adjusting the relative position (the gap between the first adhesive roller 142 and the second adhesive roller 144). The force with which the second adhesive roller 144 abuts on the sheet 10 can be easily held within a desired range.

Hereinafter, the technical significance of the first guide member 161 and the second guide member 162 will be described.
In the description of the technical significance, whether the pair of first adhesive roller 142 and second adhesive roller 144 belongs to the adhesive roller unit 141A, the adhesive roller unit 141B, the adhesive roller unit 141C, or the adhesive roller unit 141D. Since the point is not important, this point will be described without being specified.

If the sheet 10 is wound around the first adhesive roller 142, the foremost part of the sheet 10 adheres to the outer peripheral surface of the first adhesive roller 142 and is lifted upward.
However, the foremost portion of the sheet 10 lifted upward eventually comes into contact with the lower surface of the first guide member 161, and the foremost portion of the sheet 10 is restricted from moving upward from the lower surface of the first guide member 161.
As a result, the foremost part of the sheet 10 is peeled off from the outer peripheral surface of the first adhesive roller 142 and passes through the original conveyance path (if the foremost part of the sheet 10 does not wrap around the outer peripheral surface of the first adhesive roller 142. It will return to the conveyance path of the wax sheet 10.

Further, if the sheet 10 is wound around the second adhesive roller 144, the foremost part of the sheet 10 adheres to the outer peripheral surface of the second adhesive roller 144 and is pulled downward.
However, the foremost part of the sheet 10 pulled downward is in contact with the upper surface of the second guide member 162 and the foremost part of the sheet 10 is restricted from moving below the upper surface of the second guide member 162.
As a result, the foremost part of the sheet 10 is peeled off from the outer peripheral surface of the second adhesive roller 144 and passes through the original conveyance path (if the foremost part of the sheet 10 is not wrapped around the outer peripheral surface of the second adhesive roller 144) It will return to the conveyance path of the wax sheet 10.

  In this way, the position where the first guide member 161 is in contact with the first adhesive roller 142 and faces the upper surface (first sheet surface) of the sheet 10 (held between the first adhesive roller 142 and the second adhesive roller 144). The second guide member 162 is in contact with the second adhesive roller 144 (positioned between the first adhesive roller 142 and the second adhesive roller 144) and faces the lower surface (second sheet surface) of the sheet 10 Since the front end of the sheet 10 is peeled again even if it is wound around the first adhesive roller 142 or the second adhesive roller 144, the sheet 10 is wound around the first adhesive roller 142 or the second adhesive roller 144. It is possible to prevent the situation of sticking (more reliably than in the case where the first guide member 161 and the second guide member 162 are not provided).

In the present embodiment, the first adhesive roller 142 and the second adhesive roller 144 in the adhesive roller unit 141A, the first adhesive roller 142 and the second adhesive roller 144 in the adhesive roller unit 141B, and the first adhesive roller 142 and the second adhesive roller in the adhesive roller unit 141C. The two adhesive rollers 144 and the first adhesive roller 142 and the second adhesive roller 144 in the adhesive roller unit 141D are both rotationally driven by the adhesive roller driving device 150, but the present invention is not limited to this.
For example, only one of the first adhesive roller and the second adhesive roller may be rotationally driven, and the other may not be rotationally driven (abuts on the sheet-like material and rotates as the sheet-like material moves).
