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 imparting an uneven pattern to a synthetic resin molded product or a molded product made of a black iso 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 into contact with the surface of the molded product 11 and transferring the uneven pattern 2 of the embossing roll A to the molded product 11. This 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, and the embossing roll If a part of the uneven pattern is damaged, it is necessary to discard the entire embossing roll, which raises the problem of high costs in terms of equipment and materials. Also, both sides of the molded product need to be cut and removed as ears, but conventionally, the molded product is given a uniform concave shape as shown in Figure 5, and then both sides of the molded product are cut. However, there was also the problem that a special process for cutting the ears was needed, 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 the horizontal pattern by replacing the horizontal board for patterning, and also to easily carry out repairs. It is an object of the present invention to provide an embossing roll which can be used to cut edges and which eliminates the need for a special process for cutting edges.

E Disclosure of the Invention The embossing roll according to the present invention has a plurality of pattern plates 3 having irregularities 2 formed on the outer surface thereof, arranged around the entire circumference of the roll core 1, so as to form a ring shape. Stop 4 to be formed
is divided into a plurality of divided bodies 5 in the circumferential direction, and stoppers 4 are arranged on the outer periphery of both ends of the roll core 1, and they are removably attached with bolts 6, and the pattern plate 3 is attached to the roll core 1 with the stoppers 4. The cutter piece 7 provided on the stopper 4 allows the pattern board 3 to The above object has been achieved by making it possible to cut the edges of the molded product at the same time as forming the uneven pattern, and further by making it possible to replace the horizontal plate 3 with the roll core 1 by removing the stopper 4. The present invention will now be described in detail with reference to Examples.

The pattern plate 3 is formed by providing an uneven horizontal pattern 2 on the surface to give an uneven pattern to the molded product, and the inner and outer surfaces are clean and white with a miniaturized curvature equal to the curvature of the outer peripheral surface of the roll core 1. It is formed as a board.

The width of the curved side of the pattern board 3 is set to an integer fraction such as 1/2 of the 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. The dimensions of the pattern board 3 may be set according to the dimensions of the molded 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 the figure. It is formed into a split configuration. A cutter piece 7 with a sharp tip is projected over the entire circumference of the stop 11:4, and a 7-runchi 13 extends inward from the outer side end of the stop 4. This 7-run no. 13 is provided with a bolt through hole 14.

゛Also, a rotating shaft 16 is provided protruding from both ends of the roll core 1, which is the base of the embossing roll.
A screw hole 15 is surrounded by both gA'R1 surfaces.

Therefore, the horizontal plates 3, 3 are arranged around the outer periphery of the roll core 1 as shown in FIG. ,
As shown in FIG. 3, with the pair of divided bodies 5 butted against each other in a ring shape, the bolt through holes 14 of the seven runs 13 of each divided body 5 are
A bolt 6 is passed through the roll core 1, and the bolt 6 is screwed into the screw hole 15 of the roll core 1. 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 ends of the pattern plate 3 are placed between the stops 4 and the outer periphery of the roll core 1. As shown in FIG.
is fixed to the outer periphery of the roll core 1. By attaching the pattern plate 3 to the roll core 1 with the fasteners 4 in this way, it is possible to create an embossing roll A in which the uneven horizontal pattern 2 of the horizontal plate 3 as shown in FIG. 1 is provided on the outer periphery. It is a monkey. In the case shown in FIG. 1, bolt holes 14 are provided on the outer circumference of the stop J44, and screw holes 15 are provided on the outer circumferential surface of both ends of the roll core 1, and the stop i4:4 is provided on the outer circumference. Then, bolt 6 is fixed to roll core 1.

The embossing roll A thus formed is brought into soft contact with the surface of the molded product 11 immediately after extrusion, as shown in FIG.
It is used to impart an uneven lateral pattern to the molded product 11 by the uneven lateral pattern 2 of the lateral plate 3. In this product, when giving the molded product 11 an uneven horizontal pattern by the uneven horizontal pattern 2 of the horizontal plate 3, the cutter piece 5 of the stopper 4 bites into the molded product 11 as shown in FIG. This means 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 the molded product 11;
Since the molded product 11 has just been extruded, it is possible to easily remove the ear portion by hand or the like, even if the ear portion is only dug into the molded product 11 by about half of its wall thickness. 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 may be placed above the take-off belt 12 as shown in FIG. 5, or the receiver following the take-off belt 12 may be placed above the roll 17. But that's fine.

Further, when changing the uneven pattern to be applied to the molded product 11 on 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.

In this case, the stopper 4 is designed so that it can be removed from the roll core 1 while being divided into 5 parts.
There is no need to remove the embossing roll A from the bearing of the rotary drive device, and the stopper 4 can be removed while it is attached to the rotary drive device. By removing the stopper J44 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, and the pattern board 3 provided with the different uneven pattern 2 is removed from the pattern board 3 as described above. It is to be attached to the roll core 1 in the same manner as above. Therefore, by simply sharing the roll core 1 and changing the pattern plate 3, it is possible to easily accommodate changes in the design. In addition, if a part of the uneven pattern 2 is damaged, by replacing the damaged pattern board 3 with a new one,
This means that the embossing roll A can be easily repaired. When repairing the pattern plate 3 itself, the pattern plate 3 can be easily repaired with the pattern plate 3 removed from the roll core 1.

[Effect of the Invention J 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. The stoppers were placed on the outer periphery of both ends of the roll core and were 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 and the stopper was attached By removing the presser, the pattern plate can be removed from the roll core, and by simply changing and replacing the pattern plate while sharing the roll core, it is possible to easily change the horizontal appearance of the molded product. 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 multiple embossing rolls for different patterns or to discard the embossing rolls themselves.Moreover, cutter pieces are protruded from the outer surface of this stopper over the entire circumference. Therefore, when applying the uneven pattern to the molded product due to the uneven pattern on the pattern board, the cutter piece of the stopper bites into the molded product, and the stopper for fixing the pattern plate is used to apply the uneven pattern to the molded product. It is possible to cut the edges on both sides of the molded product at the same time, eliminating the need for a special process for cutting the edges.Also, the ring-shaped stopper can be divided into multiple parts in the circumferential direction. Since the body is divided into two parts, the embossing roll can be removed from the roll core while being divided into two parts, and the embossing roll can remain attached to the rotary drive device without having to remove it from the bearing of the rotary drive device. The fastener can be easily removed.
