Description

Technical Field

[0001] The present invention relates to a surface treatment member and a surface treatment system.

Background Art

[0002] When performing coating on building materials and the like, it is preferable to carry out substrate adjustment before coating. The substrate adjustment refers to a treatment for bringing the surface of an object to be coated into a state suitable for coating. If coating is performed without carrying out substrate adjustment, the adhesion of the coating material may decrease due to the presence of foreign matter (such as rust and old coating films), and the object to be coated may not be sufficiently protected. Note that the substrate adjustment may also be referred to as surface preparation, descaling, or the like in some cases.

[0003] The substrate adjustment can be carried out, for example, using a grinding tool provided with a disk-type or belt-type grinder (sander) (see, for example, Patent Document 1). The substrate adjustment can also be carried out using a rotary tool provided with an annular brush (see, for example, Patent Document 2). Furthermore, the substrate adjustment can also be carried out by a method of spraying granular materials onto the treatment target (blasting method) (see, for example, Patent Document 3).

Summary of Invention

Problems to be Solved by the Invention

[0005] However, when surface preparation is performed using conventional grinding tools or rotary tools, a scratch-like pattern is formed on the surface to be treated, resulting in lower paint adhesion compared to surface preparation using the blast method, which forms dot-like irregularities on the surface to be treated. On the other hand, surface preparation using the blast method has the problem of not being easily implemented due to the need for extensive preparation beforehand and the generation of a large amount of waste.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide a surface treatment system and a surface treatment member for use in the surface treatment system that can improve the adhesion of paint and allow for easy surface preparation. [Means for solving the problem]

[0007] [1] The surface treatment member of the present invention is a surface treatment member for use attached to a rotating member in a surface treatment system comprising a rotating member, comprising a base that can be attached to the rotating member, and a striking member that is rotatably attached to the base and strikes the object to be surface treated when in use, wherein the base has a stopper that defines the rotation angle of the striking member.

[0008] [2] In the surface treatment member of the present invention, it is preferable that the striking member has an acute-angled impact portion.

[0009] [3] In the surface treatment member of the present invention, when the surface treatment member is viewed along a virtual axis on which the base should rotate, the stopper is preferably configured such that the striking member is located below the virtual axis in the direction of gravity, and the imaginary line connecting the virtual axis and the rotation axis of the striking member is parallel to the direction of gravity, and the collision portion is located behind the imaginary line in the direction of rotation.

[0010] [4] In the surface treatment member of the present invention, it is preferable that the surface treatment member comprises a plurality of striking members, and the rotation axis of the striking members is arranged on a circumference centered on a virtual axis that should rotate the base.

[0011] [5] In the surface treatment member of the present invention, it is preferable that the stopper is arranged to overlap with the virtual axis and to define the rotation angles of the plurality of striking members.

[0012] [6] In the surface treatment member of the present invention, when the surface treatment member is viewed along the virtual axis, the outer edge of the base is preferably circular in shape with respect to the virtual axis, and the striking member is preferably partially exposed outside the outer edge of the base due to centrifugal force when the surface treatment member rotates, and can be retracted inward from the outer edge of the base after colliding with the object to be surface treated.

[0013] [7] The surface treatment system of the present invention is a surface treatment system comprising a rotating member that is rotatable by a driving means and a surface treatment member attached to the rotating member, wherein the surface treatment member comprises a base attached to the rotating member and a striking member that is rotatably attached to the base and strikes the object to be surface treated when in use, and the base has a stopper that defines the rotation angle of the striking member.

[0014] [8] In the surface treatment system of the present invention, it is preferable that a guide member is further provided that extends beyond the base toward the surface to be treated when in use, and when viewed along the rotation axis of the rotating member, a portion of the striking member is exposed beyond the outer edge of the guide member due to centrifugal force when the surface treatment member rotates, and the entire striking member can be retracted inward from the outer edge of the guide member after colliding with the surface to be treated. [Effects of the Invention]

[0015] The surface treatment member of the present invention comprises a base that can be attached to a rotating member, and a striking member that is rotatably attached to the base and strikes the surface to be treated when in use, the base having a stopper that defines the rotation angle of the striking member. Therefore, when surface preparation is performed using a surface treatment system that utilizes the surface treatment member of the present invention, the striking member rotates quickly after striking the surface to be treated and detaches from the surface to be treated, so that dot-shaped irregularities are formed on the surface to be treated rather than scratch-like patterns. Therefore, by using the surface treatment member of the present invention as part of a surface treatment system, it is possible to improve the adhesion of paint when surface preparation is performed. Furthermore, by using the surface treatment member of the present invention as part of a surface treatment system, it can be used in the same way as conventional grinding tools and rotary tools, making surface preparation easy to perform.

[0016] The surface treatment system of the present invention, by comprising the surface treatment member of the present invention, is a surface treatment system that can improve the adhesion of paint and can easily perform surface preparation. [Brief explanation of the drawing]

[0018] Hereinafter, the surface treatment member and the surface treatment system of the present invention will be described based on each embodiment shown in the drawings. Each drawing is a schematic diagram, and does not necessarily strictly reflect the actual structure and configuration. The embodiments described below do not limit the invention according to the claims. In addition, not all of the elements described in each embodiment and combinations thereof are essential to the present invention. In the following description, components that can be regarded as substantially equivalent may be denoted by the same reference numerals across embodiments, and repeated descriptions may be omitted.

[0019] [Embodiment 1] 1. Surface Treatment Member 1 First, the surface treatment member 1 according to Embodiment 1 will be described. FIG. 1 and FIG. 2 are diagrams shown for explaining the surface treatment member 1 according to Embodiment 1. FIG. 1(a) is a front view of the surface treatment member 1 when not in use (at rest), FIG. 1(b) is a rear view of FIG. 1(a), FIG. 1(c) is a right side view of FIG. 1(a), and FIG. 1(d) is a view with the striking member 40 hidden from FIG. 1(c). FIG. 2(a) is a front view of the surface treatment member 1 during use (during rotation), and FIG. 2(b) is a front view showing a state where all the striking members 40 are retracted inward from the outer edge of the base 10. Note that in FIG. 1 and FIG. 2, the downward direction in the drawings is the direction of gravity. This also applies to the front views and right side views described later. In addition, in FIG. 1(c), since the number of illustrated striking members 40 is large, reference numerals are only indicated for some of the striking members 40. This also applies to the right side views and plan views (top views) described later. Figure 3 is a diagram illustrating the striking member 40 in Embodiment 1. Figure 3(a) is a front view of the striking member 40, and Figure 3(b) is a right side view of Figure 3(a). In Figure 3, the striking member 40 is shown enlarged compared to Figures 1 and 2.

[0020] The surface treatment member 1 is a surface treatment member used by being attached to the rotating member 110 in a surface treatment system 100 (described later) that includes a rotating member 110. As shown in Figures 1 and 2, the surface treatment member 1 comprises a base 10, a striking member 40, and a shaft member 50.

[0021] The base 10 is a component that can be attached to the rotating member 110. The base 10 has a first circular member 12, a second circular member 14, and a stopper 20. The first circular member 12 and the second circular member 14 are disc-shaped components that, when viewed as in Figures 1(a) and 1(b), have a circular shape centered on a virtual axis A on which the base 10 should rotate. The stopper 20 is a component that defines the rotation angle of the striking member 40. In Embodiment 1, the stopper 20 is also a shaft component that is positioned along the virtual axis A on which the base 10 should rotate and connects the first circular member 12 and the second circular member 14. The stopper 20 will be described again after the striking member 40 is described. Note that the base 10 may have other components (for example, components for fixing or joining each component). When the surface treatment member 1 is viewed along the virtual axis A (as shown in Figure 1(a) or Figure 1(b)), the outer edge of the base 10 has a circular shape centered on the virtual axis A.

[0022] On the side of the second circular member 14 in the base 10, a mounting hole 16 corresponding to the mounting portion 112 (described later) of the rotating member 110 is formed (see Figure 1(b)).

[0023] Each component constituting the base 10 can be made from a material based on, for example, metal, resin, or rubber. These components may consist of a single material or multiple materials.

[0024] The striking member 40 is rotatably mounted on the base 10 and is a member that strikes the surface to be treated when in use. As shown in Figure 3, the striking member 40 has an acute-angled impact portion 42. The impact portion 42 of the striking member 40 can also be described as the part that collides with the surface to be treated when the surface treatment system 100 is used in an appropriate manner. The impact portion 42 is oriented toward the forward side in the rotational direction in which the surface treatment member 1 should be rotated. The striking member 40 also has an axial hole 44 through which the shaft member 50 passes.

[0025] The specific shape, constituent materials, and physical properties of the striking member 40 can be appropriately determined according to the intended use. The striking member 40 in Embodiment 1 can be manufactured, for example, by processing a metal plate. The hardness of the impact portion 42 is preferably 40 or higher on the Rockwell C scale. It is also preferable that the entire striking member 40 falls within the above hardness range. By achieving the above hardness, it becomes possible to form sufficient irregularities on the surface to be treated, even on steel materials.

[0026] When the surface treatment member 1 is viewed along the virtual axis A, when the surface treatment member 1 rotates, a portion of the striking member 40 (including the impact portion 42) is exposed outside the outer edge of the base 10 due to centrifugal force (see Figure 2(a)), and after impacting the surface treatment object, the entire striking member 40 can retract inward from the outer edge of the base 10 (see Figure 2(b)). This retraction does not depend on the deformation (bending, stretching, etc.) of the base 10 and the striking member 40. This will be explained in detail in the section "Behavior of the striking member 40 when surface preparation is performed with the surface treatment system 100".

[0027] When the surface treatment member 1 is viewed along the virtual axis A on which the base 10 should rotate, the stopper 20 defines the rotation angle of the striking member 40 as follows: That is, when the striking member 40 is positioned below the virtual axis A in the direction of gravity, and the virtual line V connecting the virtual axis A and the rotation axis of the striking member 40 (center of the shaft member 50) is parallel to the direction of gravity (see Figures 1(a) and 1(b)), the stopper 20 defines the rotation angle of the striking member 40 so that the impact part 42 is positioned behind the virtual line V in the direction of rotation.

[0028] The surface treatment member 1 comprises a plurality of striking members 40. The rotation axis (center of the shaft member 50) of the striking member 40 is positioned on a circumference centered on a virtual axis A that should rotate the base 10. The stopper 20 is positioned to overlap with the virtual axis A and defines the rotation angles of the plurality (all in Embodiment 1) striking members 40.

[0029] In Embodiment 1, 30 striking members 40 are mounted in a row along the direction of the virtual axis A (see Figure 1(c)). Furthermore, these constitute one set, and the surface treatment member 1 comprises three sets of striking members 40. Note that these are examples, and the number of striking members mounted in a row and the number of sets can be appropriately set depending on the type of surface to be treated. Each striking member 40 is mounted independently. This arrangement of striking members 40 makes it possible to smoothly perform surface preparation even if the surface to be treated has irregularities or curved surfaces.

[0030] The shaft member 50 is a rod-shaped member positioned to pass through the shaft hole 44 of the striking member 40 and fixed to the base 10. The shaft member 50 can also be described as a member for attaching the striking member 40 to the base 10.

[0031] 2. Surface treatment system 100 Next, the surface treatment system 100 according to Embodiment 1 will be described. Figures 4 and 5 are diagrams illustrating the surface treatment system 100 according to Embodiment 1. Figure 4 can also be described as a diagram showing the surface treatment member 1 removed from the rotating member 110. Figure 4(a) is a front view, and Figure 4(b) is a top view. Figure 5 can also be described as a diagram showing the surface treatment member 1 attached to the rotating member 110. Figure 5(a) is a front view showing the surface treatment member 1 in a stationary state, Figure 5(b) is a top view of Figure 5(a), and Figure 5(c) is a front view showing the surface treatment member 1 in a rotating state.

[0032] The surface treatment system 100 according to Embodiment 1 comprises a surface treatment member 1, a rotating member 110, and a grip portion 120, as shown in Figures 4 and 5. The surface treatment system 100 can also be viewed as a handheld power tool (rotary tool). In addition to the components described above, the surface treatment system 100 also includes components necessary for rotational drive, but since known components can be used, their description and illustration are omitted. Furthermore, the surface treatment system 100 may also include non-essential components (for example, a cover to prevent dust scattering or an auxiliary handle) in addition to the components described above.

[0033] In this specification, "surface treatment system" refers to a combination of devices and components that can be used for surface treatment. The surface treatment system as used herein is not limited to handheld power tools like surface treatment system 100, but may also include, for example, remotely operated or automated robots or drones. Furthermore, the applications of the surface treatment system of the present invention are not limited to surface preparation of objects to be painted. The surface treatment system of the present invention can also be used, for example, for surface treatment of adhesive surfaces or for surface treatment to improve aesthetics.

[0034] The surface treatment member 1 is attached to the rotating member 110. In the surface treatment system 100, the mounting portion 112 (see Figure 4) of the rotating member 110 is inserted into the mounting hole 16 of the surface treatment member 1 (base 10). In Embodiment 1, the mounting portion 112 is made of a hexagonal prism-shaped member and the mounting hole 16 is made of a hexagonal prism-shaped hole, which is an example. The shape of the mounting portion and the mounting hole is not particularly limited as long as the rotational force of the rotating member can be transmitted to the surface treatment member. Furthermore, the mounting portion and the mounting hole may have a structure or mechanism (for example, a grooved shape or a locking mechanism) to prevent the surface treatment member 1 from unintentionally detaching. Moreover, as long as it is possible to attach the surface treatment member to the rotating member, the structure or mechanism for doing so is not limited to a combination of a mounting portion and a mounting hole.

[0035] The rotating member 110 is a member that can be rotated by a driving means (not shown). The rotating member 110 has a mounting portion 112 that corresponds to the mounting hole 16. When the surface treatment member 1 is rotated, the rotating member 110 is connected to a driving means that generates rotational force by some means (e.g., gear, belt, shaft, etc.). The type of driving means is not particularly limited, but examples include using an electric motor, a pressure motor (e.g., a pneumatic motor, a hydraulic motor, and a water pressure motor), or an internal combustion engine.

[0036] The grip portion 120 is the part that the user holds in their hand when using the device. The grip portion 120 may incorporate various mechanisms (for example, all or part of the drive mechanism, a transmission, a transformer, etc.).

[0037] 3. Behavior of the striking member 40 when surface preparation is performed with the surface treatment system 100. Next, we will explain the behavior of the striking member 40 when surface preparation is performed (during actual use). Figure 6 is a diagram illustrating the behavior of the striking member 40 in the surface treatment system 100 according to Embodiment 1. Figures 6(a) to 6(d) show the movement of the surface treatment member 1 and the striking member 40 over time. In Figure 6, for clarity, only one striking member 40 is shown, and the components of the surface treatment system 100 other than the surface treatment member 1 are omitted from the illustration. In Figure 6, the arrow shown on the left side of the surface treatment member 1 indicates the direction of rotation of the surface treatment member 1. In Figure 6, foreign matter (such as old paint or rust) that may be present on the surface treatment target T is omitted from the illustration.

[0038] The striking member 40, which is attached to the base 10 that rotates together with the rotating member 110 via the shaft member 50, is partially exposed outside the outer edge of the base 10 due to centrifugal force when the surface treatment member 1 rotates (see Figure 6(a)). As the base 10 rotates, the striking member 40 approaches the surface treatment target T and collides with it (see Figure 6(b)). At this time, the impact portion 42 of the striking member 40 forms a dot-shaped indentation on the surface treatment target T. After colliding with the surface treatment target T, the striking member 40 rotates as if bouncing up due to the recoil of the collision, and its entirety can be retracted inward from the outer edge of the base 10 (see Figure 6(c)). With the striking member 40 retracted inward from the outer edge of the base 10, it passes through the part where the base 10 and the surface treatment target T are closest together. After that, due to centrifugal force, a part of the striking member 40 is once again exposed outside the outer edge of the base 10 (see Figure 6(d)).

[0039] Although the striking member 40 may come into contact with the surface treatment target T when it passes through the area where the base 10 and the surface treatment target T are closest, the striking member 40 does not have much force at this time, so a scratch-like pattern is hardly formed.

[0040] The rotation angle of the striking member 40 is defined by the stopper 20 (see Figures 6(a) and 6(b)). In particular, in Embodiment 1, the stopper 20 defines the rotation angle of the striking member 40 so that the striking member 40 is located below the virtual axis A in the direction of gravity, and the virtual line V connecting the virtual axis A and the rotation axis of the striking member 40 (center of the shaft member 50) is parallel to the direction of gravity, so that the collision portion 42 is located behind the virtual line V in the direction of rotation. Therefore, when the collision portion 42 of the striking member 40 collides with the surface treatment target T, the collision portion 42 collides with the surface treatment target T at a position away from the rotation axis of the striking member 40 and the surface treatment target (see Figure 6(b)). Therefore, the striking member 40 rotates smoothly after the collision with the surface treatment target T.

[0041] 4. Effects The effects of the surface treatment member 1 and surface treatment system 100 according to Embodiment 1 will be described below.

[0042] The surface treatment member 1 according to Embodiment 1 comprises a base 10 that can be attached to a rotating member 110, and a striking member 40 that is rotatably attached to the base 10 and strikes the surface to be treated when in use. The base 10 has a stopper 20 that defines the rotation angle of the striking member 40. Therefore, by performing surface preparation using the surface treatment system 100 that uses the surface treatment member 1 according to Embodiment 1, the striking member 40 rotates quickly after striking the surface to be treated, and the impact portion 42 in particular detaches from the surface to be treated, so that dot-shaped irregularities are formed on the surface to be treated rather than scratch-like patterns. Therefore, by using the surface treatment member 1 according to Embodiment 1 as part of the surface treatment system 100, it is possible to improve the adhesion of paint when surface preparation is performed. Furthermore, by using the surface treatment member 1 according to Embodiment 1 as part of the surface treatment system 100, it can be used in the same way as conventional grinding tools and rotary tools, making surface preparation easy to perform.

[0043] Furthermore, according to the surface treatment member 1 of Embodiment 1, since the striking member 40 is rotatably mounted to the base 10, compared to surface treatment members where the movement of the striking member depends on the deformation of the base and the striking member (for example, an annular brush described in Patent Document 2), it is possible to reduce the repulsive force generated when surface preparation is performed and to reduce the force required to hold the surface treatment system 100 in the appropriate position.

[0044] Furthermore, according to the surface treatment member 1 of Embodiment 1, the base 10 has a stopper 20 that defines the rotation angle of the striking member 40, making it possible to control the rotation of the striking member 40 and cause it to collide appropriately with the surface treatment target.

[0045] Furthermore, according to the surface treatment member 1 of Embodiment 1, since the striking member 40 has an acute-angled impact portion 42, it is possible to form fine and deep indentations on the surface to be treated.

[0046] Furthermore, according to the surface treatment member 1 of Embodiment 1, when the surface treatment member 1 is viewed along the virtual axis A on which the base 10 should rotate, the stopper 20 defines the rotation angle of the striking member 40 such that the striking member 40 is located below the virtual axis A in the direction of gravity, and the virtual line V connecting the virtual axis A and the rotation axis of the striking member 40 is parallel to the direction of gravity, and the collision portion 42 is located behind the virtual line V in the direction of rotation. This makes it possible to make the collision portion 42 collide with the surface treatment target T at a position away from the rotation axis of the striking member 40 and the surface treatment target. As a result, the striking member 40 can be rotated smoothly after the collision with the surface treatment target T, and as a result it is possible to suppress excessive load on the striking member 40 and other members during the collision with the surface treatment target.

[0047] Furthermore, according to the surface treatment member 1 of Embodiment 1, the surface treatment member 1 is equipped with a plurality of striking members 40, and the rotation axes of the striking members 40 are arranged on a circumference centered on a virtual axis A that should rotate the base 10, so that the load (impact) when colliding with the surface treatment object can be made to be about the same for all striking members 40.

[0048] Furthermore, according to the surface treatment member 1 of Embodiment 1, the stopper 20 is positioned to overlap with the virtual axis A and defines the rotation angle of the multiple striking members 40. Compared to the case where a stopper is provided for each striking member 40 arranged on the circumference centered on the virtual axis A (see Embodiment 2), the number of members can be reduced, resulting in a more compact structure. An advantage of this compact structure is that it allows for surface preparation of metal materials forming narrow spaces (for example, joints placed at road joints).

[0049] Furthermore, according to the surface treatment member 1 of Embodiment 1, when the surface treatment member 1 is viewed along the virtual axis A, the outer edge of the base 10 has a circular shape centered on the virtual axis A, and when the surface treatment member 1 rotates, a portion of the striking member 40 is exposed outside the outer edge of the base 10 due to centrifugal force, and after impacting the surface treatment object, the entire striking member 40 can be retracted inside the outer edge of the base 10. For this reason, even when surface treatment is performed and the surface treatment object and the base 10 of the surface treatment member 1 come very close to or almost come into contact, it is possible to suppress the formation of scratch-like patterns and to suppress damage to the components constituting the surface treatment member 1.

[0050] The surface treatment system 100 according to Embodiment 1 is a surface treatment system that, because it includes the surface treatment member 1 according to Embodiment 1, can improve the adhesion of paint and allows for easy surface preparation.

[0051] [Embodiment 2] Figures 7 and 8 are diagrams illustrating the surface treatment member 2 according to Embodiment 2. Figure 7(a) is a front view of the surface treatment member 2 when not in use (stationary), Figure 7(b) is a rear view of Figure 7(a), Figure 7(c) is a right side view of Figure 7(a), and Figure 7(d) is a view of Figure 7(c) with the striking members 40 hidden. Figure 8(a) is a front view of the surface treatment member 2 when in use (rotating), and Figure 8(b) is a front view showing all striking members 40 retracted inward from the outer edge of the base 10a.

[0052] The surface treatment member 2 according to Embodiment 2 has basically the same configuration as the surface treatment member 1 according to Embodiment 1, but the configuration of the base differs from that of the surface treatment member 1 according to Embodiment 1. As shown in Figures 7 and 8, the base 10a of the surface treatment member 2 has a first circular member 12a, a second circular member 14a, a shaft member 22, and a stopper 60. Note that the components of the surface treatment member 2 other than the base 10a are the same as those of the surface treatment member 1 in Embodiment 1, so their description is omitted.

[0053] The first circular member 12a and the second circular member 14a have a circular shape with a larger diameter than the first circular member 12 and the second circular member 14 in Embodiment 1 when viewed along the virtual axis A on which the base 10a should rotate (see Figures 7(a) and 7(b)). The shaft member 22 has substantially the same configuration as the stopper 20 in Embodiment 1, but since the base 10a is provided with a separate stopper 60, it does not function as a stopper that defines the rotation angle of the striking member 40.

[0054] The base 10a has three stoppers 60. Each stopper 60 defines the rotation angle of a set of striking members 40 that are mounted side by side along the virtual axis A (see Figure 8(a)).

[0055] The surface treatment member 2 according to Embodiment 2 has a different base configuration than the surface treatment member 1 according to Embodiment 1, but it comprises a base 10a that can be attached to a rotating member, and a striking member 40 that is rotatably attached to the base 10a and strikes the surface to be treated when in use, and the base 10a has a stopper 60 that defines the rotation angle of the striking member 40.Therefore, similar to the surface treatment member 1 according to Embodiment 1, when used in a surface treatment system equipped with a rotating member, it becomes possible to improve the adhesion of the paint when surface preparation is performed, and the surface preparation can be easily performed.

[0056] Furthermore, according to the surface treatment member 2 of Embodiment 2, since the base 10a has multiple stoppers 60, it is possible to reduce the load on a single stopper 60 compared to the case where there is only one stopper.

[0057] Furthermore, according to the surface treatment member 2 of Embodiment 2, since the shaft member 22 and the stopper 60 are separate components, it is possible to increase the degree of freedom in the configuration.

[0058] The surface treatment member 2 according to Embodiment 2 also has the effects of the surface treatment member 1 according to Embodiment 1 described in Embodiment 1.

[0059] [Embodiment 3] Figures 9 and 10 are diagrams illustrating the surface treatment system 200 according to Embodiment 3. Figure 9(a) is a front view showing the surface treatment member 3 in a stationary state, and Figure 9(b) is a top view (top view) of Figure 9(a). Figure 10(a) is a front view showing the surface treatment member 3 in a rotating state, and Figure 10(b) is a front view showing all the striking members 40 retracted inward from the outer edge of the guide member 210.

[0060] The surface treatment system 200 according to Embodiment 3 has basically the same configuration as the surface treatment system 100 according to Embodiment 1, but differs from the surface treatment system 100 according to Embodiment 1 in that the configuration of the surface treatment members is different and it further includes a guide member. As shown in Figures 9 and 10, the surface treatment system 200 according to Embodiment 3 includes a surface treatment member 3, a rotating member 110, a grip portion 120, and a guide member 210. Of these, the rotating member 110 and the grip portion 120 are the same as those in the surface treatment system 100 according to Embodiment 1. The surface treatment system 200 according to Embodiment 3 will be described below, focusing on the differences from the surface treatment system 100 according to Embodiment 1.

[0061] The surface treatment member 3 is attached to the rotating member 110. The surface treatment member 3 comprises a base 10b attached to the rotating member, a striking member 40, and a shaft member 50. Of these, the striking member 40 and the shaft member 50 are the same as those in Embodiment 1.

[0062] The base 10b has a first circular member 12b, a second circular member 14b, and a stopper 20 (see Figures 9(a) and 9(b)). When viewed along the axis of rotation of the rotating member 110, the outer edge of the base 10b has a circular shape centered on the axis of rotation, but its diameter is smaller than that of the base 10 in Embodiment 1. Therefore, when the surface treatment member 3 is viewed alone, the striking member 40 cannot be retracted inward beyond the outer edge of the base 10b after colliding with the surface treatment object (see Figure 10(b)).

[0063] The guide member 210 is a member that protrudes from the base 10a toward the surface to be treated when in use. It is preferable that the guide member 210 be detachable from the viewpoint of ease of removal and installation of the surface treatment member 3.

[0064] In the surface treatment system 200, when viewed along the rotation axis of the rotating member 110, the striking member 40 is partially exposed outside the outer edge of the guide member 210 due to centrifugal force when the surface treatment member rotates (see Figure 10(a)), and after impacting the surface treatment object, the entire striking member can be retracted inside the outer edge of the guide member 210 (see Figure 10(b)).

[0065] The surface treatment system 200 according to Embodiment 3 differs from the surface treatment system 100 according to Embodiment 1 in that the configuration of the surface treatment members is different and it further includes a guide member. However, the surface treatment member 3 includes a base 10b attached to a rotating member 110 and a striking member 40 that is rotatably attached to the base 10b and strikes the surface to be treated when in use. The base 10b has a stopper 20 that defines the rotation angle of the striking member 40. Therefore, similar to the surface treatment system 100 according to Embodiment 1, it is possible to achieve high adhesion of the paint and to easily perform surface preparation.

[0066] Furthermore, according to the surface treatment system 200 of Embodiment 3, a guide member 210 is provided that extends beyond the base 10b toward the surface treatment target when in use. When viewed along the rotation axis of the rotating member 110, the striking member 40 is partially exposed beyond the outer edge of the guide member 210 due to centrifugal force when the surface treatment member rotates, and after impacting the surface treatment target, the entire striking member 40 can retract inward beyond the outer edge of the guide member 210. Therefore, even if the striking member 40 cannot be retracted inward beyond the outer edge of the base 10b when the surface treatment member 3 is viewed alone, the guide member 210 contacts the surface treatment target, thereby suppressing the formation of scratch-like patterns and preventing damage to the components constituting the surface treatment member 3.

[0067] Although the present invention has been described above based on the embodiments described above, the present invention is not limited to the embodiments described above. It can be implemented in various forms without departing from the spirit of the invention, and for example, the following modifications are also possible.

[0068] (1) The shapes, numbers, positions, etc. of the components described in each of the above embodiments are illustrative examples and can be changed within the scope that does not impair the effects of the present invention.

[0069] (2) The surface treatment member of the present invention may further include a position adjustment member (spacer, etc.) for preventing contact between adjacent striking members.

[0070] (3) In the surface treatment member of the present invention, the striking member may have an axis for rotation, and an axis hole for passing the axis may be formed in the base. [Industrial applicability]
