Description

Spin Window System

[0001] The present invention relates to a spin window system, and more specifically, to a spin window system in which a fixed-side ring plate with an electromagnet coil inserted therein and a rotating-side ring plate with a permanent magnet inserted therein are arranged at the edges of the base viewing window and the rotating viewing window, and the rotating viewing window is driven by a brushless motor structure, thereby simplifying and reducing the design of the rotating shaft part so that the field of view through the base viewing window and the rotating viewing window can be extensively expanded, and in particular, positive pressure is created in the space between the base viewing window and the rotating viewing window, thereby effectively blocking contamination caused by the inflow of foreign substances.

[0002]

[0003] Typically, a spin window is a device that utilizes a high-speed rotating glass plate to rapidly remove deposits, including any liquids or dust, accumulated on the glass. It is primarily applied to viewing windows in the machine tool or shipping industries to remove rain, waves, or large amounts of liquids, such as coolants in the case of machine tools, that adhere to the window and obstruct the view.

[0004] In addition, spin windows are mostly formed with a circular design, and various types of driving devices, such as synchronous electric motors, asynchronous motors, pneumatic motors, or hydraulic motors arranged in the center of the spin window, are applied.

[0005] The previously disclosed published patent No. 10-2021-0033948 describes a driving device having an annular stator unit, an annular rotor unit, and a base plate, wherein the stator unit has three or more coils having a coil core and a coil bobbin, the rotor unit has a bearing unit, the coils form a receiving space in the stator unit, and the coil core and the bearing unit stand on the base plate.

[0006] However, although the aforementioned prior art aims to improve the drive unit in terms of overall height and energy efficiency, it suffers from the problem of obstructing visibility because the drive unit is positioned in the center of the spin window and the cable supplying power to the drive unit is routed across the spin window.

[0007]

[0008] Accordingly, the present invention was conceived to solve the aforementioned problems, and aims to provide a spin window system in which a fixed-side ring plate with an electromagnet coil inserted and a rotating-side ring plate with a permanent magnet inserted are positioned at the edges of the base viewing window and the rotating viewing window, and the rotating viewing window is driven by a brushless motor structure, thereby simplifying and reducing the design of the rotating shaft, so that the field of view through the base viewing window and the rotating viewing window can be extensively expanded, and in particular, positive pressure is created in the space between the base viewing window and the rotating viewing window, thereby effectively blocking contamination caused by the inflow of foreign substances.

[0009]

[0010] To achieve this purpose, the features of the present invention are,

[0011] A base viewing window (10) having a first center hole (11) formed through it in the center;

[0021] A connecting cap (26) mounted in the second center hole (31) of the rotating viewing window (30) and having a fastening hole (26a) penetrating the center, and

[0022] It is characterized by including a center bolt (27) that fastens the connecting cap (26) to the center shaft (25) in a state where it is screwed into the female screw hole (24) via the fastening hole (26a).

[0024] In addition, key grooves (23a) are formed on both sides of the connecting flange (23), and a pair of stop keys (26a) protrude on the connecting cap (26) corresponding to the key grooves (23a).

[0025] The above stop key (26a) is engaged with the keyway (23a) and is configured so that the connecting flange (23) and the connecting cap (26) are connected.

[0026]

[0027] In addition, the fixed-side ring plate (40) and the rotating-side ring plate (50) are provided so that foreign substances cannot enter from the outside by means of a labyrinth strap part (60), and

[0028] The above labyrinth strap section (60) is,

[0029] A pocket inner ring (62) formed on the circumferential surface of a fixed-side ring plate (40) and having a sawtooth-shaped inclined pocket (61) formed on the outer surface, and

[0047] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Furthermore, in describing the present invention, detailed descriptions of related known functions are omitted if they are deemed obvious to those skilled in the art and could unnecessarily obscure the essence of the invention.

[0049] The present invention relates to a spin window system, wherein a fixed-side ring plate with an electromagnet coil inserted therein and a rotating-side ring plate with a permanent magnet inserted therein are positioned at the edges of the base viewing window and the rotating viewing window, and the rotating viewing window is driven by a brushless motor structure, thereby simplifying and reducing the design of the rotating shaft part so that the field of view through the base viewing window and the rotating viewing window can be extensively expanded, and in particular, positive pressure is created in the space between the base viewing window and the rotating viewing window so that contamination caused by the inflow of foreign substances can be effectively blocked, and the main components include a base viewing window (10), a rotating shaft part (20), a rotating viewing window (30), a fixed-side ring plate (40), and a rotating-side ring plate (50).

[0050] The base viewing window (10) according to the present invention has a first center hole (11) formed through it in the center.

[0051] The above base viewing window (10) is formed of a material capable of external viewing, including tempered glass and transparent synthetic resin, and is installed in a position where a view must be secured while mounted on a fixed-side ring plate (40) described later.

[0052] In addition, the rotating shaft portion (20) according to the present invention is installed in the first center hole (11) of the base viewing window (10).

[0053] The above-mentioned rotating shaft (20) is provided to rotatably support the rotating viewing window (30) described later while mounted on the base viewing window (10).

[0054] In FIGS. 2 and 3, the rotating shaft portion (20) includes a guide ring (21) inserted into the first center hole (11), a bearing (22) installed on the inner circumference of the guide ring (21), a center shaft (25) which is fastened to one end of the inner ring of the bearing (22) and has a connecting flange (23) formed on the other end and a female screw hole (24) formed in the center, a connecting cap (26) which is mounted in the second center hole (31) of the rotating viewing window (30) and has a fastening hole (26a) penetrating through the center, and a center bolt (27) which fastens the connecting cap (26) to the center shaft (25) in a state where it is screwed into the female screw hole (24) via the fastening hole (26a).

[0055] At this time, the center shaft (25) is simply restrained by having a snap ring attached to the end while one end is inserted into the inner ring of the bearing (22).

[0056] As such, since the rotational viewing window (30) is installed in a structure that allows for simple rotation by the rotational shaft (20), there is an advantage in that the field of view through the base viewing window (10) and the rotational viewing window (30) is expanded by designing the size of the rotational shaft (20).

[0057] In FIG. 4, key grooves (23a) are formed on both sides of the connecting flange (23), and a pair of stop keys (26a) protrude on the connecting cap (26) corresponding to the key grooves (23a).

[0058] In addition, the connecting flange (23) and the connecting cap (26) are connected in such a way that the stop key (26a) engages with the keyway (23a), thereby preventing the connecting cap (26) from coming loose while the rotating viewing window (30) is rotating.

[0059] In addition, the rotating viewing window (30) according to the present invention has a second center hole (31) formed in the center so as to be fastened to the rotating shaft part (20).

[0060] The above-mentioned rotating viewing window (30) is formed of a material capable of external viewing, including reinforced glass and transparent synthetic resin.

[0061] In addition, the above-described rotating viewing window (30) is rotated around the rotation axis (20) by a brushless motor structure using an electromagnet coil (41) and a permanent magnet (51) described later, and is equipped to prevent foreign substances from adhering to the rotating viewing window (30) by utilizing centrifugal force, and to remove contaminants including rainwater and foreign substances attached to the rotating viewing window (30), thereby ensuring visibility even in poor environments.

[0062] In addition, the fixed-side ring plate (40) according to the present invention is installed to finish the edge area of ​​the base viewing window (10), and a plurality of electromagnet coils (41) are spaced apart and arranged in the outer circumference direction of the base viewing window (10).

[0063] The above fixed-side ring plate (40) is formed in an annular shape and is installed at a position where a view needs to be secured while accommodating the outer surface of the base viewing window (10).

[0064] And, the fixed side ring plate (40) is provided to maintain airtightness between the base viewing window (10) and the installation surface that needs to secure a view using an airtight seal.

[0065] At this time, the electromagnet coil (41) is positioned at a location corresponding to the permanent magnet (51) described later to form a brushless motor. At this time, the electromagnet coil (41) is arranged radially around the rotation shaft (20) and is finished with a coating layer containing epoxy to provide a waterproof function.

[0066] In addition, the rotating side ring plate (50) according to the present invention is positioned at the edge of the rotating viewing window (30) corresponding to the fixed side ring plate (40), and permanent magnets (51) are provided at predetermined intervals.

[0067] The above permanent magnet (51) is positioned at a location corresponding to the electromagnet coil (41) to form a brushless motor. At this time, the permanent magnet (51) is arranged radially around the rotation shaft (20) and is finished with a coating layer containing epoxy to provide a waterproof function.

[0068] As such, the fixed-side ring plate (40) with the electromagnet coil (41) inserted therein and the rotating-side ring plate (50) with the permanent magnet (51) inserted therein are arranged at the edges of the base viewing window (10) and the rotating viewing window (30), and as the structure is improved so that the rotating viewing window (30) is driven by a brushless motor structure, there is an advantage in that the field of view through the base viewing window (10) and the rotating viewing window (30) can be widely expanded through the simplified and reduced design of the rotating shaft part (20).

[0069] In FIG. 5, the fixed-side ring plate (40) and the rotating-side ring plate (50) are provided so that foreign substances cannot enter from the outside by the labyrinth strap portion (60).

[0070] The above labyrinth strap portion (60) includes a pocket inner ring (62) formed on the circumferential surface of a fixed-side ring plate (40) and having a sawtooth-shaped inclined pocket (61) formed on its outer surface, and a pocket outer ring (64) formed protruding from the edge of a rotating-side ring plate (50) to surround the pocket inner ring (62) and having an inner pocket groove (63) formed on its inner surface corresponding to the sawtooth-shaped inclined pocket (61).

[0071] In this way, the movement of foreign substances entering from the outside is interfered with by the above-mentioned sawtooth-shaped inclined pocket (61), thereby blocking the entry of foreign substances into the space between the base viewing window (10) and the rotating viewing window (30).

[0072] Meanwhile, as shown in FIG. 5, the above-mentioned sawtooth-shaped inclined pocket (61) is formed such that an inclined section formed at a downward inclination angle as it moves toward the inner direction of the pocket inner ring (62) and the pocket outer ring (64), and a vertical section formed vertically at the lower end of the inclined section are continuously and repeatedly formed, so that external contaminants interfere with the vertical section and their movement is restricted, and the discharge of compressed air within the space between the base viewing window (10) and the rotating viewing window (30) is effectively achieved by the positive pressure creation module (70) described later.

[0073] In FIG. 6, a positive pressure forming module (70) is provided to block the inflow of external foreign substances that form positive pressure between the base viewing window (10) and the rotating viewing window (30).

[0075] In addition, positive pressure is created in the space between the base viewing window (10) and the rotating viewing window (30) by the compressed air output through the distribution channel (72), and the compressed air is discharged through the labyrinth strap section (60) into the space between the base viewing window (10) and the rotating viewing window (30), thereby blocking the inflow of external foreign substances.
