Abstract

PROBLEM TO BE SOLVED: To trim a thing by sticking film wider than a plate on the plate by adjusting this thereafter to a width of the plate, by providing a trim blade arranged by turning an edge toward the upstream, in a position contacting with the plate side end in the advancing direction of the plate to be supplied. SOLUTION: Since a trim blade 1L is inclined so that the upper side comes close to a film F surface with the feeding direction of a stainless steel plate P as the axis, a film F exists on the stainless steel plate P, and is trimmed in a trapezoidal shape, and hardly peels off from the stailess steel plate P. Since the trim blade 1L is inclined so that an edge comes close to the stainless steel plate P with the vertical direction as the axis, the film F is trimmed exactly along a width of the stainless steel plate P. A trim selvage winder 2 winds a trim selvage F2 trimmed by the trim blade 1L round a shaft. A pressing-down roller 3 restrains an angle low when the trim selvage F2 separates from a plate feed line of the stainless steel plate P.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sticking film trimming device, and more particularly to a sticking film trimming device for trimming a portion of a wide film stuck to a plate surface of a coil made of stainless steel or the like from the plate width.

[0002]

2. Description of the Related Art Conventionally, a protective film has been applied to a stainless sheet or the like used for an interior wall, an exterior wall, or the like in order to prevent a flaw from being formed during processing and installation of the sheet. Then, for the film sticking operation, the film preliminarily trimmed to the width of the stainless steel sheet is a stage before the stainless steel plate is divided into sheets, that is, the stainless steel plate wound in a coil shape is unwound. In a state of being affixed on the line.

[0003]

However, in the above method, the width of the film expands and contracts due to a change in air temperature and a change in the tension of the film due to acceleration / deceleration of the line, so that the width of the film to be attached is within a tolerance. Was difficult.

The present invention has been made to solve the above-mentioned problems, and it is possible to trim a film having a width wider than that of a stainless steel plate attached to the stainless steel plate in advance to match the width of the stainless steel plate P. It is an object of the present invention to provide a sticking film trimming device that can be used.

[0005]

According to the first aspect of the present invention,
What is claimed is: 1. A sticking film trimming device which is installed on a line to which a plate P having a film F wider than the plate width is attached is supplied, wherein a side edge of the plate P with respect to a traveling direction of the supplied plate P A trim blade 1 installed with the cutting edge 11 facing upstream at a position in contact with a trim, and a trim located downstream of the trim blade 1 and above the plate P and cut by the trim blade 11 Trim ear collecting means 2 for collecting ear F2
And a position between the trim ear collecting means 2 and the trim blade 1 at a position in contact with the plate P or below a straight line connecting the trim blade 1 and the trim ear collecting means 2 and Board P
And a holding unit 3 installed at a position higher than the above.

Here, the term “upper” in this specification refers to
A side on which the film F is attached to the plate P,
The “lower side” is the side where the film F is not attached to the plate P. Further, “upward” is a direction perpendicular to the plate P and is a direction toward “upper”. "Downward" means plate P
And a direction toward “downward”.
Since the present invention does not utilize gravity, it is not bound by the general “up and down”.

[0007] "Upstream" is the direction in which the plate P is transported, and "Downstream" is the direction in which the plate P is transported. The “position between the trim ear collecting means 2 and the trim blade 1” is a position upstream of the trim ear collecting means 2 and downstream of a contact point between the trim blade 1 and the plate P. It is.

In the present invention, the holding portion 3 is installed at the above-mentioned position with respect to the upstream and downstream, and at the position where it contacts the plate P with respect to the up and down. Alternatively, it is installed at the above position with respect to upstream and downstream, and at a position below the straight line connecting the trim blade 1 and the trim ear collecting means 2 and above the plate P with respect to the up and down. In any case,
It does not change that the holding portion 3 is installed below the straight line connecting the trim blade 1 and the trim ear collecting means 2.

Here, the "straight line connecting the trim blade 1 and the trim ear collecting means 2" refers to the contact point between the trim blade 1 and the plate P, the receiving portion of the trim ear collecting means 2 for the trim ear F2,
And the straight line where the trim ear F2 would be located on the line without the restraining portion 3.
In the drawings to be referred to, the reference numerals of a pair of left and right members are suffixed with R and L to distinguish between left and right.
In the present invention, since each member does not necessarily have to be a pair of left and right, R and L are not described at the end of the reference numerals in the description of each part of the present invention.

Since the adhesive film trimming device of the present invention has the trim blade 1 installed with the cutting edge 11 facing upstream at a position in contact with the side end of the plate P with respect to the traveling direction of the supplied plate P, , A wide film attached to the surface of the board P,
It can be trimmed along the width of the plate P. In the present specification, "trim" refers to cutting and removing unnecessary portions exceeding the width of the plate of the wide film attached to the plate surface.
It is assumed that. Further, since the trim ear collecting means 2 is installed at a position downstream of the trim blade 1 and above the plate P, the cut trim ears F2 may interfere with the passing of the plate P. It can be collected without.

Further, since the adhesive film trimming device of the present invention has the holding portion 3, the trimmed ear F2 is trimmed.
Can be reduced when separated from the threading line by the trim ear collecting means 2. That is, as described above, it is desirable that the trim ears F2 be collected above the plate P so as not to hinder the passage of the plate P. But,
If the angle at which the trim ear F2 is separated upward from the threading line by the trim ear collecting means 2 is large, the trim ear F2
Film F on the upstream side of trim blade 1
The film F before trimming is peeled off the plate P. The restraining portion 3 prevents such a situation by reducing the angle at which the trim ear F2 is separated from the passing line.

According to a second aspect of the present invention, there is provided the adhesive film trimming device according to the first aspect, wherein the trim blade 1 is moved from a position perpendicular to a feeding direction and a width direction of the plate P.
The upper side is inclined toward the surface of the film F with the feed direction of the plate P as an axis. Here, in this specification, when describing the posture (inclination) of the trim blade 1, “plate P
From the position perpendicular to the feed direction and the width direction ”, but this description is for the convenience of the description of how to tilt, and the position of the trim blade 1 is set to one axis from the position. It is not limited to only the inclination.

That is, the trim blade 1 can be tilted about axes of the feed direction of the plate P, the width direction of the plate P, and the vertical direction.
It is needless to say that the plate P can be inclined by two axes or three axes from a posture perpendicular to the feed direction and the width direction. In the present invention, since the trimming blade 1 is inclined from the position perpendicular to the feeding direction and the width direction of the plate P to the film F side toward the film F surface around the feeding direction of the plate P as an axis, the plate P The upper sticking film F can be trimmed into a substantially trapezoidal cross-sectional shape whose front side is narrowed (see FIG. 2).

When the adhesive film F is wider than the plate P even after trimming, it is obvious that the adhesive film F is easily peeled off, but the width of the surface of the adhesive film F to be attached to the plate P is along the width of the plate P. Even in the case where the front side of the adhesive film F is wide, the adhesive film F is likely to be similarly peeled. The adhesive film trimming device of the present invention includes:
By tilting the trim blade 1 toward the surface of the film F,
The sticking film F is trimmed to have a substantially trapezoidal cross-sectional shape whose surface is narrowed, thereby preventing such a situation.

According to a third aspect of the present invention, there is provided the adhesive film trimming device according to the second aspect, wherein the trim blade 1 is moved from a position perpendicular to a feeding direction and a width direction of the plate P.
The upper side is inclined downstream with respect to the width direction of the plate P. In the present invention, the trim blade 1 is inclined downstream from the attachment film F side around the width direction of the plate P from an attitude perpendicular to the feeding direction and the width direction of the plate P (see FIG. 1). For this reason, the resistance received by the trim blade 1 when cutting the film can be reduced, and smooth trimming is possible. And since the trim blade 1 is slanted in the direction of passing the plate P, the contact distance between the trim blade 1 and the side end of the plate P can be increased, and the trim blade 1 contacts the side end of the plate P more stably. As a result, the film F can be trimmed stably along the edge of the plate P.

According to a fourth aspect of the present invention, there is provided the adhesive film trimming device according to the third aspect, wherein the trim blade 1 is moved from a position perpendicular to a feeding direction and a width direction of the plate P.
The cutting edge 11 is inclined so as to be closer to the plate P with the vertical direction as an axis. In the present invention, the trim blade 1 has the cutting edge 11 inclined toward the plate P about the vertical direction. If the inclination is not present and the trim blade 1 is installed in parallel along the passing direction of the plate P, the position of the cutting edge 11 is separated from the side end of the plate P by at least the thickness of the trim blade 1. Will be. Then, the film F after trimming
Is slightly wider than the width of the plate P, and the film F
Is easily peeled off.

In the adhesive film trimming device of the present invention, the trimming blade 1 is tilted so that the cutting edge 11 is close to the plate P, so that the film can be trimmed accurately along the width of the plate P (FIG. 3). If the above inclination is not provided, the entire blade of the trim blade 1 comes into contact with the plate P side end in the front-rear direction, which increases the resistance and causes the blade to break. The sticking film trim device of the present invention prevents such a situation by providing the above-mentioned inclination.

According to a fifth aspect of the present invention, there is provided the adhesive film trimming device according to the first aspect, wherein the trim blade 1 is mounted on the slide portion 4 which can be moved to a desired position in the width direction of the plate P. Is what is being done. According to the present invention, the trim blade 1 can be moved to an arbitrary position in the width direction of the plate P by the slide portion 4, so that the trim blade 1 can be accurately attached to a side end of a plate of various widths. It can be brought into contact.

According to a sixth aspect of the present invention, there is provided the apparatus for trimming an affixed film according to the fourth or fifth aspect, wherein the trim ear collecting means 2 comprises a trim ear winding shaft which rotates.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a sticking film trimming device according to an embodiment of the present invention.

(1) Configuration of the Adhesive Film Trim Device of the Present Embodiment The adhesive film trim device of the present embodiment is installed on a line for attaching a film F to a stainless steel plate P, as shown in FIGS. It is used for trimming a portion of the adhesive film F protruding from the side end of the stainless steel plate P. Therefore, at the time of trimming, the position of the stainless steel plate P is fixed by a line feed roll or the like. In this line, the width is 400 to 16
It is possible to pass the stainless steel plate P having a thickness of 00 mm and a thickness of 0.2 to 2.0 mm.

The sticking film trimming device of the present embodiment comprises:
It has a trim blade 1, a trim ear take-up device 2, a holding roll 3, a slide portion 4, and a ball joint 5. In the drawings, R and L are added to the end of the reference numerals of a pair of left and right members to distinguish left and right. However, in the description of the embodiment, R and L are used unless otherwise required. L is not added. Here, the “right” is the right side when it is on the stainless steel plate P and goes downstream. “Left” is the left side when it is on the stainless steel plate P and goes downstream.

As shown in FIG. 2, the trim blade 1 is connected to the slide portion 4 via a ball joint 5,
The slide portion 4 can move to any position in the width direction of the stainless steel plate P. As shown in FIG. 1, the trim ear take-up device 2 is installed at a position about 50 cm downstream of the trim blade 1 and about 100 cm above it, and the pressing roll 3 is provided with the trim blade 1 and the trim ear. About 15 cm behind the trim blade 1 between the winding device 2 and about 1 cm from the surface of the stainless steel plate P on the film sticking side.
cm above.

The trim blade 1 is a blade having a predetermined length. The trim blade 1 is installed at a position in contact with both ends with respect to the traveling direction of the supplied stainless steel plate P with the blade edge 11 facing upstream. With this trim blade, stainless steel plate P
The protruding film F is trimmed along the width of the stainless steel plate P. It is convenient for the trim blade 1 to be a knife capable of sequentially breaking and removing a worn blade and sending out a new blade. That is, in the present film trimming apparatus, the trim blades 1 continuously cut the film and are in contact with the plate side end, so that the wear is considered to be fast. When the trim blade 1 is a knife as described above, a worn blade can be easily removed and a new blade can be used, and the sharpness of the trim blade 1 can be easily maintained.

Further, since the trim blade 1 is installed in the apparatus by a ball joint 5 as shown in FIG. 4, the trim blade 1 is moved from a posture perpendicular to the feed direction and the width direction of the stainless steel plate P in three axial directions (stainless steel plate). The posture can be changed within a range of about 30 degrees each in the width direction of P, the feeding direction of the stainless steel plate P, and the vertical direction. This ball joint 5
As a result, the upper side of the trim blade 1 is tilted downstream with respect to the width direction of the stainless steel plate P as shown in FIG. 1, and the upper side of the film F with respect to the feed direction of the stainless steel plate P as shown by the broken line in FIG. The blade 11 is tilted toward the stainless steel plate P about the vertical direction as shown in FIG. In addition, in FIG. 3, the broken line shows the width of the stainless steel plate P.

Since the trim blade 1 is tilted upward at the upper side with respect to the width direction of the stainless steel plate P, the resistance at the time of trimming the film F by the trim blade 1 is reduced. In addition, since the trim blade 1 is inclined upward toward the surface of the film F with the feed direction of the stainless steel plate P as an axis, the film F is trimmed into a substantially trapezoidal shape on the stainless steel plate P, and is hardly peeled off from the plate. Since the trim blade 1 is tilted with the cutting edge 11 toward the stainless steel plate P about the vertical direction, the film F can be trimmed exactly along the width of the stainless steel plate P.

The trim ear take-up device 2 is a device for winding the trim ear F2 trimmed by the trim blade 1 around a shaft. The trim ear winding devices 2 are provided one by one above the downstream of the trim blade 1. The winding shaft is rotating at a peripheral speed substantially equal to the line speed of the stainless steel plate P. Trim ear take-up device 2
Is located above the stainless steel plate P and the trim blade 1, the trim ears F2 can be collected without obstructing the passage of the stainless steel plate P. Further, since the trim ear winding device 2 is a system in which the trim ear F2 is wound around a shaft, the trim ear F2 can be continuously collected.

Although the trim ear winding devices 2 are provided one by one on the downstream side of the trim blade 1, each may be a single device with one winding shaft. This can simplify the device. Further, the winding portion may be reciprocated in the axial direction simultaneously with the rotation of the shaft. By doing so,
It is possible to prevent the trim ears F2 from being intensively wound around one position on the winding shaft, and the frequency of collecting the trim ears F2 from the trim ear winding device 2 can be reduced. Then, even if the same amount of trim ears F2 is collected, the outer circumference of the wound trim ears F2 becomes smaller, and even when the shaft is rotated at a constant speed, the collecting speed of the trim ears F2 increases. Can be kept low.

The pressing roll 3 is a device that functions to reduce the angle at which the trim ear F2 trimmed by the trim blade 1 separates from the threading line of the stainless steel plate P. The pressing rolls 3 are provided one by one behind the trim blade 1. As described above, in order not to interfere with the passing of the stainless steel plate P, the trim ear F2
It is desirable to collect at a position away from the threading line.
However, assuming that the trim ear F2 is separated from the trim position by the trim blade 1 at a steep angle, the trim ear F2 is pulled by the trim ear F2 to reach the adhesive film F upstream of the trim blade 1 from the threading line. Peel off from stainless plate P. The pressing roll 3 is located below a straight line connecting the trim blade 1 and the trim ear take-up device 2, so that the angle at which the trim ear F 2 separates from the threading line of the stainless steel plate P is reduced. And prevent such a situation.

Since the roll suppresses the angle, the press roll 3 can smoothly feed the trim ear F2, and the trim ear F2 due to friction or snagging.
Troubles, such as breakage, can be reduced. In addition,
The pressing rolls 3 may have one roll each behind the trim blade 1, but may have one roll on the line.

The slide portion 4 supports the trim blade 1 via a ball joint 5, and can move to an arbitrary position in the plate width direction. Trim blade 1
Are provided on the left and right of the stainless steel plate P, and a pair of slide portions 4 are also provided on the left and right. As shown in FIG.
, A moving shaft 42, and a support shaft 43. Then, the moving shaft 42 and the support shaft 43
It is installed in the width direction on the stainless steel plate P, and both penetrate the moving block. Then, the trim blade 1 is installed on the moving block 41.

The moving shaft 42 and the moving block 41
There is a relationship between a bolt and a nut, and when the moving shaft 42 rotates, the moving block 41 corresponding to the nut moves on the moving shaft. At this time, the support shaft 43 prevents the moving block 41 from rotating integrally with the moving shaft 42. Since the posture of the moving block 41 is fixed by the support shaft 43, the moving block 41 is moved by the rotation of the moving shaft 42.

The moving shaft 42 is connected to the rotating handle 4.
4 is connected to the rotary handle 4
4 by operating the moving shaft 42,
The position of the trim blade 1 can be adjusted by moving the moving block 41. In the present embodiment, the rotating handles 44R and 44L are provided on the same left side by shifting the positions of the left and right moving shafts 42R and 42L and extending the right moving shaft 42R to the left. Therefore, the user can easily adjust the positions of the left and right trim blades 1R and 1L on the left side.

The ball joint 5 connects the trim blade 1 and the moving block 4 as shown in FIG. The ball joint 5 includes a male joint 51 and a female joint 52, both of which are connected with a joint outer shell 521 of the female joint 52 covering the ball portion 511 of the male joint 51, as shown in FIG. . For this reason, the male joint 51 is
Can be freely set in a range of about 30 degrees.

The ball joint 5 has the joint fixing screw 53 penetrating through the joint outer shell 521 and in contact with the ball portion 511. 52
1 and the joint fixing screw 53 firmly sandwich the ball portion 511, so that the relative angle of the male joint 51 with respect to the female joint 52 can be fixed. As a result, the trim blade 1 is fixed in an arbitrary posture.
