Description

Detailed Description of the Invention [Technical Field] The present invention relates to an embossing roll for forming an uneven pattern on the surface of a synthetic resin extrusion molded product, a cement extrusion molded product, etc. immediately after extrusion.

[Background Art] When giving an uneven pattern to a synthetic resin molded product or a molded product of an inorganic material such as cement, especially in the case of an extrusion molded product, immediately after extrusion from a mold 10 onto a take-off belt 12 as shown in FIG. Conventionally, an uneven pattern has been formed on the molded product 11 by rolling the embossing roll A onto the surface of the molded product 11 and transferring the uneven pattern 2 of the embossing roll A to the molded product 11. There is. The embossing roll A is formed by providing an uneven pattern 2 corresponding to the pattern to be applied to the molded product 11 on the outer peripheral surface by engraving or the like.

However, when forming an uneven pattern on a molded product, the shape of the uneven pattern differs depending on the product, so it is necessary to prepare multiple embossing rolls with uneven patterns according to the shape. If a part of the uneven pattern is damaged, it is necessary to discard the entire embossing roll, resulting in a problem of high costs in terms of equipment and materials. Additionally, both sides of the molded product need to be cut and removed as ears, but conventionally the molded product is patterned with concave and convex patterns as shown in Figure 5, and then both sides of the molded product are cut. There was also the problem that it required a special cutting process, which increased the number of man-hours.

[Object of the Invention] The present invention has been made in view of the above points, and it is possible to easily change the shape of a pattern by replacing the pattern board for patterning, and also to easily carry out repairs. It is an object of the present invention to provide an embossing roll that can be used to cut edges and that does not require a special process for cutting edges.

[Disclosure of the Invention] Accordingly, the embossing roll according to the present invention has a plurality of pattern plates 3 having uneven patterns 2 formed on the outer surface arranged around the entire circumference of the roll core 1 to form a ring shape. A stopper 4 is divided into a plurality of divided bodies 5 in the circumferential direction.
, and the stoppers 4 are arranged on the outer periphery of both ends of the roll core 1 and removably attached with bolts 6, and the pattern plate 3 is pressed and fixed to the outer periphery of the roll core 1 by the stoppers 4, It is characterized by having a cutter piece 7 protruding from the outer surface of the stopper 4 over the entire circumference, and the cutter piece 7 provided on the stopper 4 allows the pattern board 3 to form an uneven pattern at the same time. It is possible to cut the edges of the molded product, and by removing this stopper 4, the roll core 1 can be cut.
The above object has been achieved by allowing the pattern board 3 to be replaced.The present invention will be described in detail below with reference to Examples.

The pattern plate 3 is formed by providing an uneven pattern 2 on the surface to give an uneven pattern to the molded product.
It is formed as a curved plate whose inner and outer surfaces have a curvature equal to the curvature of the outer peripheral surface of the roll core 1.
The width dimension of the curved side of this pattern board 3 is set to a dimension that is an integer fraction, such as 1/2 of the circumference of the outer circumference of the roll core 1, and as shown in FIG.
is used by disposing it around the outer periphery of the roll core 1. pattern board 3
This dimension may be set according to the dimension of the molded product as a product. The stopper 4 is formed into a ring shape whose inner diameter is approximately equal to the outer diameter when the pattern plate 3 is attached to the roll core 1 as shown in FIG. Therefore, it is formed into a two-part configuration. A cutter piece 7 with a sharp tip is projected from the outer periphery of the stopper 4 over the entire circumference, and a flange 13 is extended inward from the outer side end of the stopper 4. This flange 13 has a bolt through hole 14 bored therein.
Further, a rotary shaft 16 is provided protruding from both ends of the roll core 1 which is the base of the embossing roll, and screw holes 15 are recessed in both end surfaces of the roll core 1.

Thus, the pattern plates 3, 3 are arranged around the outer periphery of the roll core 1 as shown in FIG. As shown in FIG. 3, each divided body 5
Pass the bolt 6 through the bolt through hole 14 of the flange 13, and insert the bolt 6 into the screw hole 15 of the roll core 1.
Screw together. In this way, the stops 4 formed by the pair of divided bodies 5 are fixed to both ends of the roll core 1, and the end of the pattern plate 3 is placed between the stops 4 and the outer periphery of the roll core 1. As shown in FIG. 2, the pattern plate 3 is fixed to the outer periphery of the roll core 1 by sandwiching the parts. By attaching the pattern plate 3 to the roll core 1 with the fasteners 4 in this manner, an embossing roll A is created in which the uneven pattern 2 of the pattern plate 3 as shown in FIG. 1 is provided on the outer periphery. It is something that can be done. In the case shown in FIG. 1, bolt holes 14 are provided on the outer circumference of the stopper 4, and screw holes 15 are provided on the outer circumferential surface of both ends of the roll core 1. The roll core 1 is fixed with 6 bolts.

The embossing roll A thus formed is shown in FIG.
It is used to impart an uneven pattern to the molded product 11 by the uneven pattern 2 of the pattern plate 3. In this case, when the uneven pattern 2 of the pattern plate 3 is used to impart an uneven pattern to the molded product 11, the cutter piece 5 of the stopper 4 as shown in FIG.
The molded product 11 is cut into the molded product 11, so that it is possible to cut the edges on both sides of the molded product 11 at the same time as forming the uneven pattern on the molded product 11. At this time, there is no particular need for the cutter piece 5 to penetrate through the molded product 11, and it is easy to do so by hand, as the molded product 11 has just been extruded, even if it is inserted into about half of the wall thickness of the molded product 11. The ears can be removed. Further, by providing the uneven pattern 2 on the inner side surface of the cutter piece 5, the uneven pattern can also be provided on the cut side surface of the molded product 11. The embossing roll A is placed at the fifth position.
Even if it is set at the upper position of the take-up belt 12 as shown in the figure, or the take-up belt 12
It may be set at a position above the receiving roll 17 following .

Further, when changing the uneven pattern to be applied to the molded product 11 in the embossing roll A formed in this manner, first the bolt 6 is pulled out and the stopper 4 is removed from the roll core 1. At this time, since the stopper 4 can be removed from the roll core 1 while being divided into divided bodies 5, 5, there is no need to remove the embossing roll A from the bearing of the rotary drive device. This means that the stopper 4 can be removed while still attached. By removing the stopper 4 from the embossing roll A in this manner, the holding of the stopper 4 against the pattern board 3 is released, and the pattern board 3 is removed from the roll core 1, thereby creating a pattern board with a different uneven pattern 2. 3 is attached to the roll core 1 in the same manner as described above. Therefore, by simply sharing the roll core 1 and changing the pattern plate 3, it is possible to easily respond to remodeling. Furthermore, if a part of the uneven pattern 2 is damaged, the embossing roll A can be easily repaired by replacing the damaged pattern plate 3 with a new one. When repairing the pattern board 3 itself, the pattern board 3 should be placed on the roll core 1.
This means that repairs can be easily carried out while it is removed.

[Effects of the Invention] As described above, in the present invention, a plurality of patterned plates each having an uneven pattern formed on the outer surface are arranged around the entire circumference of the roll core to form a ring shape. Stops were placed on the outer periphery of both ends of the roll core and removably attached using bolts, and the pattern plate was held and fixed to the outer periphery of the roll core using the stoppers, so the stoppers were removed from the roll core to stop it. The pattern plate can be removed from the roll core by removing the hold down by the tool, and the pattern plate can be easily changed to a molded product by simply changing and replacing the pattern plate while sharing the roll core. and
In addition, if a part of the uneven pattern is damaged, the embossing roll can be easily repaired by replacing the damaged pattern board with a new one. There is no need to prepare a plurality of embossing rolls corresponding to different patterns or to discard the embossing rolls themselves. In addition, since the cutter piece is provided protruding from the outer surface of the stopper all the way around, the cutter piece of the stopper bites into the molded product when the uneven pattern of the pattern plate is used to impart the uneven pattern to the molded product.
By using a stopper for fixing the pattern plate, it is possible to cut the edges on both sides of the molded product at the same time as adding the uneven pattern to the molded product, eliminating the need for a special process for cutting the edges. It is possible. In addition, since the ring-shaped stopper is divided into a plurality of divided bodies in the circumferential direction, the stopper can be removed from the roll core while being divided into divided bodies.
There is no need to remove the embossing roll from the bearing of the rotary drive device, and the stopper can be easily removed while it is attached to the rotary drive device.
