Upper and lower surface pressure contact rollers 21 and 22 and a side surface pressure contact roller 23 are sequentially provided. Further, a sheet cutting device 24 is provided at the discharge end.

The upper surface pasting roller 12 attaches the material 2 on the conveyor 1.
It is installed horizontally at a height that touches the top surface of the A pair of first upper edge folding rollers 13 are arranged in an inclined V-shape, and are provided at positions where they abut against both side edges of the upper surface of the material 2 on the conveyor 1 . The second upper edge folding rollers 14 are a pair of rollers that are inclined in a V-shape like the first upper edge folding rollers 13, and the angle of inclination with respect to the horizontal plane is the same as that of the first upper edge folding rollers. It is set larger than 13. A pair of side sticking rollers 15 are vertically provided so as to contact both sides of the material 2 on the conveyor 1. Lower edge bending roller 16
are arranged in a slanted manner in an inverted V-shape, and are provided at positions where they abut against both edges of the lower surface of the material 2 being conveyed by the conveyor 1. Lower surface pasting roller 17
is provided horizontally so as to be in contact with the lower surface of the material 2 being conveyed.

In such a decorative sheet coating device, the material 2 is conveyed on the conveyor 1 at a constant speed to the right in the figure.
The decorative sheet 3 is continuously fed onto the material 2 at the same speed as the material 2 conveyance speed. The decorative sheet 3 sent onto the material 2 is pressed onto the upper surface of the material 2 by the upper surface pasting roller 12 and is pasted onto this upper surface (FIG. 3A). After this, material 2 progresses and the third
As shown in Figure B, the decorative sheet 3
are bent downward from both edges of the upper surface of the material 2.
Then, as shown in FIG. 3C, the folding angle of the decorative sheet 3 is deepened by the second upper edge folding roller 14. Decorative sheet 3 folded like this
is pasted on the side surface of the material 2 by the side surface pasting roller 15 as shown in FIG. 3D. After this, Figure 3 E
When the lower edge folding rollers 16 come into contact with both edges of the lower surface of the material 2, the portion of the decorative sheet 3 extending downward from the material 2 is folded inward from the lower edge of the material 2. This folded portion of the decorative sheet 3 is pasted on the bottom surface of the material 2 in contact with the bottom surface pasting roller 17, as shown in FIG. 3F. In this way, after the decorative sheet 3 is coated over the entire circumference of the material 2, the upper and lower surface pressing rollers 18, 2
1 and 22 and side pressure rollers 20 and 23, the decorative sheet 3 is pressed against the surface of the material 2, and the decorative sheet 3 is reliably pasted. When the entire length of the material 2 is covered with the decorative sheet 3, the decorative sheet 3 is cut at the rear end of the material 2 by the sheet cutting device 24.

In this way, the decorative sheet 3 is covered, but in the above device, the folding rollers 13, 14,
16 and the positions and angles of the pasting rollers 12, 15, 17 to 23 are fixed, so there is a problem that it can only be used for materials with one type of cross-sectional shape.

Therefore, an object of this invention is to provide a decorative sheet covering roller device that allows the position and angle of the roller to be adjusted according to the cross-sectional shape of the material, and also allows fine adjustment of the roller position.

An embodiment of this invention is shown in FIGS. 4 to 10. That is, this decorative sheet covering roller device includes a fixed support shaft 25, a rotation support member 26 attached to the fixed support shaft 25 so that the rotation angle around the fixed support shaft 25 can be changed and fixed, and this rotation support member 26. A support pipe 27 is attached to the dynamic support member 26 so that its axial position can be changed and fixed, and an adjustment nut 28 is inserted through the support pipe 27 so as to be movable in the axial direction and engages with the end surface of the support pipe 27 at one end. A screwed through shaft 29, a spring member 30 that biases the through shaft 29 toward the other end, and a roller 31 rotatably held and attached to the other end of the through shaft 29 with the axis center of the through shaft 29. The roller support member 32 is attached so that the rotation angle can be changed and fixed around orthogonal axes. As shown in FIGS. 4, 6, and 7, the rotation support member 26 has split holes 33 and 34 at both ends thereof, into which the fixed support shaft 25 and the support pipe 27 are inserted, and are perpendicular to each other. There is. These split holes 33, 34 have split portions 33a, 34 along the axial direction.
A is formed up to the end face of the rotation support member 26, and the fixed support shaft of the rotation support member 26 is fixed by a bolt/nut 35 passed through the rotation support member 26 across both sides of the split portion 33a. 25 is tightened and fixed. Further, the support pipe 27 is tightened and fixed by bolts and nuts 36 passed through the rotary support member 26 across both sides of the split portion 34a at the other end. The support pipe 27 can also rotate within the split hole 34 (in the direction of arrow A in FIG. 4). The through shaft 29 has a male threaded portion 29a at one end into which the adjustment nut 28 is screwed, and a roller 3 at the other end.
It has one notch 37 (FIG. 10) for mounting. This notch 37 is provided with a pivot hole 38 . Further, a locking ring 39 (FIG. 8) is fixed near the notch 37 of the through shaft 29, and the spring member 30 is interposed between the locking ring 39 and the end surface of the support pipe 27. The support pipe 27 is provided with a long hole 40 extending in the axial direction, and a rotation prevention pin 41 that fits into the long hole 40 is implanted in the through shaft 29 . The roller 31 is made of resin or the like, and is rotatably attached to the roller support member 32 with a snap spring 42.
The roller support member 32 has a mounting hole 43 (FIG. 9), and is fastened to the pivot hole 38 of the through shaft 29 by a bolt/nut 44 inserted through the mounting hole 43. Note that this roller device is applied to support the rollers 12 to 23 of the devices shown in FIGS. 1 and 2.

With this configuration, the support pipe 27 can be moved in the axial direction (in the direction of arrow B) relative to the rotation support member 26, and the rotation support member 26 can be moved relative to the fixed support shaft 25.
By rotating it against (in the direction of arrow C),
The position of the roller 31 can be changed significantly.
Further, by rotating the rotation support member 26 and rotation of the roller support member 32 (in the direction of arrow D), the inclination angle of the roller 31 with respect to the horizontal plane can be freely changed. The angle of the roller 31 with respect to the material feeding direction can be changed by rotating the support pipe 27. Therefore, even if the material 2 is changed to one with a cross-sectional shape of various sizes,
The position and angle of the roller 31 can be adjusted so that the roller 31 contacts the edge or each surface of the material 2.

Furthermore, since the through shaft 29 is axially movable with respect to the support pipe 27 and is biased by the spring member 30, the roller 31 comes into elastic contact with the material 2. In this case, the strength of the spring member 30 can be adjusted by moving the through shaft 29 forward and backward by rotating the adjustment nut 28, so that the roller 31
The pressing pressure can be adjusted freely. Therefore, good coverage of the decorative sheet 3 can be achieved. Furthermore, by moving the through shaft 29 forward and backward with the adjustment nut 28, the position of the roller 31 can be finely adjusted, allowing accurate roller position setting.
Furthermore, since the rollers 31 are in elastic contact with the material 2 as described above, even if the material 2 is warped, the decorative sheet 3 will not be damaged due to excessive pressing force. , coating can be carried out smoothly.

As described above, the decorative sheet covering roller device of this invention includes a fixed support shaft, a rotation support member attached to the fixed support shaft so that the rotation angle around the fixed support shaft can be changed and fixed, and a support pipe attached to a support member so that its axial position can be changed and fixed; and a penetrating shaft that is inserted into the support pipe so as to be movable in the axial direction and has an adjustment nut screwed to one end that engages with the end surface of the support pipe. and a spring member that biases this through shaft toward the other end side, and a roller that is rotatably held, and fixed to the other end of the through shaft to change the rotation angle around an axis perpendicular to the axis of this through shaft. Because it is equipped with a roller support material that can be attached to the material, it is possible to adjust the position and angle of the roller according to the cross-sectional shape of the material, and it is also possible to make fine adjustments to accurately set the roller position. can be done. In addition, since the roller is in elastic contact with the material, even if the material is warped, the decorative sheet etc. can be covered smoothly without being damaged, and the pressing pressure of the roller by the spring member can be reduced. Adjustment is possible, and therefore, there is an effect that good coverage can be achieved by adjusting the pressing force to an appropriate level.
