This rotating disk deforms along the three-dimensional unevenness of the floor, and has the characteristic of being able to thoroughly polish even a somewhat uneven floor.The present inventor has created an improved rotating disk for floor maintenance made of non-woven fabric. (Japanese Utility Model Publication No. 56-29101).This rotating disk is made by three-dimensionally assembling fibers processed into loops, joining the intersections, and adhering an abrasive material to the surface of the fibers. Rotating disks for structural floor maintenance have excellent abrasive properties, but have the disadvantage of being easily deformed, because they are easily deformed in response to radial traction forces. It can withstand high-speed rotation because the centrifugal force acting on the rotating disk increases significantly in proportion to the square of the rotational speed. A rotating disk in which a reinforcing core material is laminated on a non-woven fabric is disclosed in Japanese Patent Application Laid-open No. 56-1.
It is described in Japanese Utility Model Publication No. 14670 and Japanese Utility Model Application Publication No. 57-68752. In the rotating disks described in these publications, a reinforcing core material is adhered to one side of a nonwoven fabric, and the nonwoven fabric and the reinforcing core material are laminated. The reinforcing core material not only reinforces the rotating disk and prevents deformation, but also works to forcefully press the nonwoven fabric against the surface of the object to be polished. When the nonwoven fabric is strongly pressed by the reinforcing core material, polishing efficiency improves. In other words, the reinforcing core material not only reinforces the rotating disk and prevents it from losing its shape, but also presses the nonwoven fabric against the object being polished with strong force. It is extremely important to firmly adhere the nonwoven fabric to the reinforcing core material.If the adhesion between the nonwoven fabric and the reinforcing core material is insufficient, the nonwoven fabric will lose its shape due to centrifugal force, and the nonwoven fabric will not be able to apply sufficient pressure to the surface of the object to be polished. There is no pressure. Nonwoven fabrics have countless voids between the fibers.
This causes a decrease in the strength of bonding the nonwoven fabric to the reinforcing core material. In a nonwoven fabric with many voids, the fibers can only be locally bonded to the reinforcing core material. In order to firmly bond the reinforcing core material and the nonwoven fabric, in other words, to bond the fibers to a wider number of reinforcing core materials, the conventional rotating disk for floor maintenance is
The nonwoven fabric and the reinforcing core material are bonded together with a thickly applied rubber adhesive. A thickly applied adhesive bonds the nonwoven fibers to the reinforcing core over a larger area. A rotating disk having this structure is manufactured by the following steps. ■ Soak the nonwoven fabric in liquid adhesive. Squeeze the nonwoven fabric with two rollers to remove excess adhesive. In this step, adhesive is applied to the surface of the fibers. ■ Spray abrasive grains toward the nonwoven fabric while the adhesive is uncured. In this step, abrasive grains are attached to the surface of the fibers. Then let the glue dry. ■ Apply a thick layer of rubber adhesive to the surface of the reinforcing core material that will be laminated to the nonwoven fabric. ■ When the adhesive is uncured, non-woven fabric is laminated on both sides of the reinforcing core material and bonded. ■ After the adhesive has hardened, the laminate of the nonwoven fabric and reinforcing core material is cut into a disk shape. ■ Rubber adhesives are flexible when cured. For this reason, rubber-based adhesives cannot harden (cure) the center part of the rotating disk sufficiently.In order to harden the center part of the rotating disk, a reinforcing adhesive is applied6 ■ In addition, if necessary, Press the center part and harden the adhesive in a heating oven.

The reason for this is that no matter how much rubber adhesive is used, the adhesive strength between the nonwoven fabric and the reinforcing core material cannot be sufficiently strong. Furthermore, conventional rotating discs made of non-woven fabric have the ability to uniformly polish the entire surface of the floor along three-dimensional irregularities (although they do have the feature of being able to polish the entire surface of the floor uniformly along the three-dimensional unevenness of the disk, however, due to the use of non-woven fabric, some parts of the disc may peel off during use, resulting in poor durability). In particular, when polishing a floor with protrusions, !M gets caught on the protrusions and the nonwoven fabric peels off in that area.Peeling of the nonwoven fabric has nothing to do with whether the rotating disk is new or old. Even if the rotating disk is new, it will peel off if the fibers get caught on the protrusions on the floor.For this reason, partial peeling of the rotating disk has the disadvantage of significantly shortening its lifespan, depending on where it is used.Nonwoven fabric during use The peeling is due to the manufacturing direction of the nonwoven fabric.In other words, the nonwoven fabric is made by stacking fibers without direction to achieve a predetermined thickness, and then bonding the intersection points of the #l fibers with an adhesive. If a part of the nonwoven fabric gets caught, it has the disadvantage of causing separation between the stacked layers of fibers.In order to prevent separation between the eyebrows and increase the adhesive strength between the nonwoven fabric and the reinforcing core material, the amount of adhesive used is Increasing the nonwoven fabric's excellent cushioning, which is important for rotating disks for floor maintenance, is lost because the voids in the nonwoven fabric are reduced and the surface of the fibers is covered with a thick adhesive film. Furthermore, if a large amount of adhesive is used, the life of the 5-turn disc will be shortened, and it cannot be used until it is sufficiently worn.This is because a large amount of adhesive penetrates between the nonwoven fibers, causing the nonwoven fibers to become unusable. Furthermore, conventional rotating disks for floor maintenance are extremely labor intensive and expensive to manufacture.
This is because the adhesive is applied many times during the manufacturing process and is then dried. Conventional rotating discs for floor maintenance use a single adhesive to attach abrasive grains to the fibers of a non-woven fabric, laminate the non-woven fabric and a reinforcing core material, and then harden the central part of the rotating disc. I can't. This is because the order in which adhesives are used is limited. For the nonwoven fabric, it is necessary to adhere the reinforcing core material after adhering the abrasive grains. On the contrary,
After laminating the nonwoven fabric and the reinforcing core material, abrasive grains cannot be attached to the nonwoven fabric. This is because if abrasive particles are attached to the nonwoven fabric after laminating the nonwoven fabric and the reinforcing core material, the rubber adhesive will melt and the reinforcing core material and the nonwoven fabric will separate. This invention was developed with the aim of solving these drawbacks of conventional rotating disks for floor maintenance.
An important object of the present invention is to provide a rotating disk that rotates at high speed, can polish floors efficiently, has a long lifespan, and can be mass-produced at low cost using a simple process. Another important object is to provide a rotating disk that does not lose its shape even when pressed against a floor with strong pressure. [Means for Solving the Problem] The rotating disk for floor maintenance of the present invention In order to achieve the purpose, the rotating disk has the following configuration: (a) The rotating disk has a laminated structure in which the nonwoven fabric 2 is bonded to both sides of the reinforcing core material 6 (b) The reinforcing core material 1 and the nonwoven fabric 2 The laminate is cut into a disc shape and has a through hole 3 in the center. (c) The reinforcing core material l has a through gap of nonwoven fabric fibers 4. (d) The nonwoven fabric fibers bonded to one side are reinforced. The nonwoven fabric 2 extends through the core material 1 and is bonded to the other surface. (e) The longitudinal fibers 5 of the nonwoven fabric penetrate the reinforcing core material 1;
The fibers of the nonwoven fabric 2 bonded to the other surface are bonded and bonded at the intersections. [Function] The rotating disk for floor maintenance of the present invention has two nonwoven fabrics 2
A reinforcing core material 1 is glued in between. The fibers of the nonwoven fabric 2 penetrate the reinforcing core material 1. The longitudinal fibers 5 of the nonwoven fabric passing through the reinforcing core material 1 and the nonwoven fabric fibers 4 adhered to the other surface of the reinforcing core material 1 are bonded and bonded at the intersection. That is, the longitudinal fibers 5 penetrating the reinforcing core material 1 are bonded to the nonwoven fabric fibers 4 adhered to both surfaces. The longitudinal fibers 5 of the nonwoven fabric penetrating the gaps in the reinforcing core material 1 are prevented from shifting by the reinforcing core material 1. Since the vertical fibers 5, which do not shift in position, are bonded to the nonwoven fabric fibers 4 on both sides, the nonwoven fabrics 2 bonded to both sides of the reinforcing core material 1 are firmly bonded to each other. The longitudinal fibers 5 of the nonwoven fabric penetrate the reinforcing core material 1 and extend to the nonwoven fabric 2 bonded to the other surface, and are extended in a direction intersecting the nonwoven fabric fibers 4. In other words, the longitudinal fibers 5 penetrating the reinforcing core material 1 are extended in a direction perpendicular to or intersecting the surface of the nonwoven fabric 2. The longitudinal fibers 5 of the nonwoven fabric are extended in this direction. This has the effect of preventing delamination of the nonwoven fabric 2. This is because, as shown in FIG. 1, the longitudinal fibers 5 extend in a direction penetrating the stacked nonwoven fabric fibers 4 during the nonwoven fabric manufacturing process. Further, in the rotary disk for floor maintenance of the present invention, the nonwoven fabrics 2 on both sides of the reinforcing core material 1 are bonded via the longitudinal fibers 5 of the nonwoven fabric. Nonwoven fabric 2 and reinforcing core material 1 are laminated in this state
and can be laminated without using adhesives. Therefore,
This rotating disk can be manufactured by the following process. (2) The fibers of the nonwoven fabric are passed through the reinforcing core material 1, and the reinforcing core material 1 is laminated between the two nonwoven fabrics 2. ■ Cut the laminate of the nonwoven fabric 2 and the reinforcing core material 1 into a disk shape. In this state, the nonwoven fabric 2 and the reinforcing core material 1 are not bonded together, but the fibers are entangled and maintained in a laminated state. ■ Apply adhesive to the laminate cut into discs. ■ Spray abrasive particles on the adhesive while it is still uncured. In this step, abrasive particles are attached to the fiber surface of the nonwoven fabric. ■ If necessary, use uncured adhesive. The center part is pressed to form the shape, and the adhesive is cured in a heating oven. The rotating disk manufactured by the above process can adhere abrasive grains to the surface of the fibers, as well as the nonwoven fabric and the reinforcing core material, with the adhesive applied once, and if necessary, the center of the rotating disk. Parts can also be hardened. The reason why the adhesive applied once can be used for multiple purposes is that the nonwoven fabric 2 and the reinforcing core material 1 can be laminated by entangling the fibers without using an adhesive.

However, the embodiment shown below is an example of a rotating disk for floor maintenance to embody the technical idea of the present invention, and the rotating disk for floor maintenance of the present invention has different materials such as the material of the component parts, The shape, structure, and arrangement are not limited to the following structures. The rotating disk of the present invention may be modified in various ways within the scope of the claims. Furthermore, in order to make the scope of the claims easier to understand, the numbers corresponding to the members shown in the embodiments are included in the ``Claims column'' and ``Means for Solving the Conventional Problems''. Additional notes are added to the members shown in the "Column" and "Column of Action". However, the members shown in the claims are by no means limited to the members of the embodiments. The rotating disk shown in FIG. 1 has nonwoven fabrics 2 bonded and laminated on both sides of a reinforcing core material (2). The nonwoven fabric 2 bonded to both sides of the reinforcing core material 1 becomes the polished surface of the floor (the lower surface is the polished surface in FIG. 1). Therefore, by turning the rotary disk for floor maintenance with this structure upside down, one surface can be used as a polishing surface. A rotating disk for floor maintenance is used by being attached to a rotating tool. Therefore, the rotating disk is cut into a disk shape, and a through hole 3 for fixing is opened in the center. The non-woven fabric 2 is made by bonding non-woven fabric fibers 4 in a directional manner (in addition, so that voids are formed between the fibers).The non-woven fabric 2 is made by adjusting the thickness of the non-woven fabric fibers 4 according to the purpose.Thick fibers The nonwoven fabric 2 is hard and has excellent polishing power.The nonwoven fabric 2 made of thin fibers can polish the polishing surface smoothly.For this reason, the nonwoven fabric 2 used for rough polishing of the floor has thick M fibers. The non-woven fabric 2 used for finishing polishing makes the fibers thinner.The rotating disk polishes the floor, removes dirt, or polishes it beautifully.The non-woven fabric used in the rotating disk for polishing the floor coats the fiber surface. Abrasive grains are attached.The non-woven fabric of the rotating disk that removes stains from the floor or polishes the floor adheres powder, such as viscous powder, which is softer than the abrasive grains to the fibers. A rotating disk made of non-woven fabric that does not attach abrasive grains or powder to the fibers polishes the floor with the fibers. The abrasive grains that adhere to the surface of the non-woven fibers 4 are adjusted according to the thickness of the fibers and the purpose.- Numerically speaking, abrasive particles with a large particle size are attached to thick fibers, and small abrasive particles are attached to thin fibers. Carborundum, alundum, silica, alumina, etc. can be used as the abrasive material. The thickness of the nonwoven fabric fibers 4 and the particle size of the abrasive grains vary depending on the application, but for example, the fibers of the nonwoven fabric 2 may have a
Denier, and abrasive grains of #40 to #3000 are used. The reinforcing core material 1 is made of a sheet material having voids that can penetrate the fibers of the nonwoven fabric, such as felt or a nonwoven fabric made of fine fibers made into a sheet by aggregating fibers three-dimensionally without directionality, or a single knitted yarn braided. A braided sheet, such as a net, can be used. The nonwoven fabric 2 adhered to both sides of the reinforcing core material 1 is bonded via the longitudinal fibers 5 of the nonwoven fabric. In FIG. 1, the fibers of the nonwoven fabric 2 adhered to the upper surface of the reinforcing core material 1 penetrate the reinforcing core material 1 downward. The vertical fibers 5 that have passed through the reinforcing core material 1 are extended to the nonwoven fabric 2 that is bonded to the lower surface of the reinforcing core material 1,
The vertical fibers 5 passing through the reinforcing core material 1 and the nonwoven fabric fibers 4 of the nonwoven fabric on the lower surface are bonded and bonded to each other at intersections. On the contrary, the fibers of the nonwoven fabric adhered to the lower surface of the reinforcing core material 1 penetrate upward through the reinforcing core material 1. The vertical fibers 5 that have passed through the reinforcing core material 1 are extended to the nonwoven fabric 2 that is bonded to the top surface of the reinforcing core material 1, and the vertical fibers 5 that have penetrated the reinforcing core material 1 and the nonwoven fabric fibers 4 on the top surface are at intersections. Glued and connected to each other. In the rotary disk for floor maintenance shown in FIG. 1, the fibers of the nonwoven fabric on the top surface are extended to the nonwoven fabric 2 on the bottom surface, the fibers of the nonwoven fabric on the bottom surface are extended to the nonwoven fabric on the top surface, and the nonwoven fabric A4 and the vertical fibers 5 are formed. are connected at the intersection. In this way, the rotating disk in which the fibers of the nonwoven fabric 2 bonded to both sides of the reinforcing core material 1 are bonded to each other by penetrating the reinforcing core material 1 has the feature that the nonwoven fabrics 2 on both sides can be bonded more firmly. However, in the rotary disk for floor maintenance of the present invention, it is not necessary that the fibers of the nonwoven fabric on both sides penetrate the reinforcing core material toward the nonwoven fabric on the other side. For example, although not shown, the fibers of the nonwoven fabric on one side may be passed through the reinforcing core material and bonded to the fibers of the nonwoven fabric on the other side. Furthermore, when a nonwoven fabric of felt or fine fibers is used for the reinforcing core material 1, the fine fibers 6 of the reinforcing core material 1 and the nonwoven fabric fibers 4 can be bonded at intersections. In this way, when the fine fibers 6 of the reinforcing core material and the nonwoven fabric fibers 4 are bonded at the intersection, there is an advantage that the adhesive strength between the reinforcing core material 1 and the nonwoven fabric 2 can be further strengthened. The fibers of the nonwoven fabric are passed through the reinforcing core material 1, and the reinforcing core material 1
To extend the fine fibers 6 into the nonwoven fabric 2, a hooking needle 7 is inserted from the nonwoven fabric 2 toward the reinforcing core material 1. Hook needle 7
As shown in FIG. 2, the fibers are provided with protrusions 8 on the surface that cause the fibers to be caught in the insertion direction but not in the withdrawal direction. When a hooking needle having this structure is inserted from the non-woven fabric 2, the protrusions 8 on the ridge surface hook the fibers of the non-woven fabric to penetrate the reinforcing core material 1. Further, the fine fibers of the reinforcing core material are also caught by the protrusions 8 on the ridge surface and drawn into the nonwoven fabric. When the hooking needle 7 is pulled out from the nonwoven fabric 2 and the reinforcing core material l, the protrusion 8 releases the fiber hooking state and only the hooking needle is pulled out. Therefore, the fibers of the nonwoven fabric can be penetrated into the reinforcing core material 1 by passing the hooking needle of this structure through the reinforcing core material 1 from the nonwoven fabric 2 many times. By increasing the number of times the hooking needle is inserted, or by inserting a large number of hooking needles together, the number of fibers that can be penetrated through the reinforcing core material can be increased. The rotating disk shown in FIG. 1 is made by passing the fibers of a nonwoven fabric through a reinforcing core material 1, and entangling the longitudinal fibers 5 passing through the reinforcing core material 1 with the nonwoven fabric fibers 4 bonded to the other surface. After laminating the material 1, it is cut into a disk shape. Adhesive is applied to the cut laminate, and when the adhesive has not hardened, abrasive grains are sprayed on the cut laminate, the center portion is pressed, and the laminate is transported to a drying oven to harden the adhesive. In the rotating disk manufactured in this state, the applied adhesive adheres the nonwoven fabric 2 and the reinforcing core material 1, and the nonwoven fabric fibers 4
Abrasive grains are attached to the surface of the rotating disk, and the center of the rotating disk is hardened to a pressed state. However, the rotary disk for floor maintenance of this invention does not necessarily need to be manufactured by applying adhesive once, but after temporarily fixing the reinforcing core material and the nonwoven fabric made by laminating the fibers together with adhesive, The abrasive grains can also be adhered by applying an adhesive to the nonwoven fabric to adhere the abrasive grains. Further, if the center portion of the rotating disk is to be hardened more firmly, another adhesive may be applied to the center portion of the rotating disk and then pressed. [Effects of the Invention] The rotating disk for floor maintenance of the present invention has nonwoven fabric fibers passing through a reinforcing core material, and longitudinal fibers passing through the reinforcing core material being bonded to nonwoven fabric fibers located on both sides of the reinforcing core material. There is. Therefore, the nonwoven fabrics located on both sides of the reinforcing core material can be firmly bonded to each other through the longitudinal fibers penetrating the reinforcing core material without shifting relative to the reinforcing core material. That is, the rotating disk for floor maintenance of the present invention can have a more complete integral structure of the nonwoven fabric and the reinforcing core material, and can be strongly reinforced by the reinforcing core material. Furthermore, the rotating disk of the present invention has the advantage of being able to prevent delamination of the nonwoven fabric. This is because, as shown in FIG. 1, the longitudinal fibers penetrating the reinforcing core material are extended in a direction perpendicular to or intersecting the surface of the nonwoven fabric, and are bonded to the intersections of the nonwoven fabric fibers. That is, the longitudinal fibers that penetrate the reinforcing core material and extend into the nonwoven fabric on the other side are extended in the direction that penetrates the stacked fibers in the nonwoven fabric manufacturing process, and are also bonded to the nonwoven fabric fibers. , the warp fibers in this direction can prevent delamination of the nonwoven fibers. Therefore, the rotating disk for floor maintenance of the present invention has the feature of polishing a floor with protrusions (preventing delamination that sometimes occurs). It can withstand the strong deformation force that is applied to the surface to be polished, and is also resistant to delamination due to protrusions on the floor.It has the feature that it can be attached to a rotary tool that rotates at high speed to efficiently polish the floor. The rotary disk for floor maintenance of this invention also has the features of durability and long service life.It does not deform even after long-term use, and the reinforcing core material and nonwoven fabric are bonded with a thick adhesive layer. This is because the rotating disk for floor maintenance of the present invention is made by laminating the nonwoven fabric and the reinforcing core material with the fibers entwined. ,
An adhesive that adheres abrasive grains to the surface of the fibers can be used to bond the nonwoven fabric to the reinforcing core and, if necessary, to harden the central portion of the rotating disk. Therefore, in the rotating disk of the present invention, the steps of applying an adhesive and drying the adhesive can be reduced from the conventional multiple steps to one step. The rotating disk of the present invention, which can simplify the process of applying adhesive, has the advantage of being able to reduce both manufacturing costs and material costs, and can be mass-produced at low cost. It also has the advantage of simplifying the manufacturing process and making it easy and efficient to manufacture.
