Description

Technical Field

[0001] The utility model relates to a position adjusting device. Background Art

[0002] Conventionally, a position adjustment device is sometimes used to arrange a product at a desired position during a product manufacturing process or a transportation process including packaging.

[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 6-196595

[0004] Conventional positioning devices have mechanisms capable of pushing the object to a desired position from multiple directions. For example, in the positioning device of Patent Document 1, two positioning rollers are displaced by movable members attached to each roller to position the object. The inventors of this application conducted in-depth research to determine whether such conventional positioning devices have room for further development. They found that positioning devices utilizing multiple movable members to displace multiple positioning rollers still have room for development. Utility Model Content

DETAILED DESCRIPTION

[0060] Hereinafter, the embodiments of the present invention will be described in detail. It should be noted that in order to enable those skilled in the art to fully understand the present invention, the applicant provides the following description and examples, which are not intended to limit the subject matter described in the claims. That is to say, the present invention is not particularly limited to the appropriate schemes described below, etc., and can be implemented by changing as appropriate within the scope of its purpose. It should be noted that, considering the ease of explanation or understanding of the main points, for convenience, it is sometimes divided into implementation plans, examples, etc. for illustration, but partial replacement and / or combination of the structures shown in different implementation plans, etc. is allowed. In the description of such an embodiment, sometimes repeated descriptions of substantially the same matters are omitted, and only the different points are described. In particular, the same effects produced by the same structure are sometimes not mentioned one by one for each embodiment.

[0061] In addition, in the description of this application specification, references to directions or orientations are for ease of explanation only and are not intended to limit the scope of the present invention, unless otherwise expressly stated. For example, relative terms such as "outer (or outer side, exterior, or periphery)" and "inner (or inner side, interior, or periphery)" and their derivatives should be understood as references to directions as described or shown in the figures. Similarly, "above" an element includes not only situations where it is in contact with the upper surface of the element, but also situations where it is not in contact with the upper surface of the element. In other words, "above" an element includes not only a position above the element that is separated from the element, that is, a position on the upper side of the element separated by other objects, or a position on the upper side separated by a gap, but also a position directly above the element. In addition, "above" does not necessarily refer to the upper side in the vertical direction. "Above" simply indicates the relative positional relationship of an element. In other words, unless otherwise expressly stated, the utility model is not required to be limited to a specific direction / orientation / configuration. In addition, the terms such as "set", "configure", "connect" and "install" and their derivatives are also the same. Unless otherwise clearly stated, they are not limited to direct solutions and can also refer to solutions with other elements such as fixtures.

[0062] Unless otherwise specified, the various numerical ranges mentioned in this specification are intended to include the numerical values of the lower and upper limits themselves. It should be noted that the term "about" means that a variation or difference of a few percent, such as ±10%, may be included.

[0063] The “vertical” and “substantially vertical” mentioned in this specification do not necessarily mean completely “vertical”, and include solutions that are slightly offset therefrom (for example, within a range of ±10° from completely vertical, for example, up to a range of ±5°).

[0064] In addition, the term “substantially parallel” in this specification may not necessarily mean completely “parallel”, and may include slightly deviated versions thereof (for example, within a range of ±10° from completely parallel, for example, within a range of ±5°).

[0065] The terms "viewed from above" or "shape viewed from above" in this specification are based on schematic diagrams of the object viewed from above, in a direction substantially perpendicular to the direction in which the frame extends. Furthermore, the term "viewed from the side" in this specification is based on the shape as seen from the direction in which the frame extends.

[0066] The terms "upward and downward directions" and "leftward and rightward directions" used directly or indirectly in this specification correspond to the vertical directions and leftward and rightward directions, respectively, in the accompanying drawings. Unless otherwise specified, identical reference numerals or symbols denote identical components / parts or have identical meanings. In certain appropriate embodiments, it can be understood that the vertical downward direction (i.e., the direction of gravity) corresponds to the "downward direction," and the opposite direction corresponds to the "upward direction."

[0067] Figure 1 and Figure 2 1 and 2 are schematic perspective views and schematic top views respectively showing a position adjustment device before operation according to an embodiment of the present disclosure. Figure 3 and Figure 4 1 and 2 are a schematic perspective view and a schematic plan view respectively showing the position adjustment device after operation according to one embodiment of the present disclosure. Figure 5 This is an exploded perspective view schematically illustrating a position adjustment device according to one embodiment of the present disclosure. The position adjustment device 1 may include: a frame 20 having a position adjustment mechanism for adjusting the position of an object; a support frame 15 supporting the frame 20; a drive device 30 driving the position adjustment mechanism of the frame 20; and a stand 10 supporting the frame 20, the support frame 15, and the drive device 30.

[0068] (stand)

[0069] Figure 6 It is a perspective view of the stand 10 in one embodiment of the present disclosure. Figure 6 The structure of the stand 10 shown is only an example and is not particularly limited as long as the support frame 15 and the drive device 30 described below can be installed. For example, the stand 10 may have a support frame 15 (see Figure 5 ) and a drive device mounting portion 14 on which a drive device 30 can be mounted. The arm 12 can support the support frame 15 and the frame-shaped body mounted on the support frame 15. Preferably, the arm 12 is configured to maintain a state in which the central area 50 of the frame-shaped body 20 mounted on the support frame 15 extends in the horizontal direction. In addition, the arm 12 and the drive device mounting portion 14 can be configured to be able to be raised and lowered along a direction Y (for example, a vertical direction) perpendicular to the extension direction of the central area 50. By raising and lowering the arm 12 and the drive device mounting portion 14 together, the frame-shaped body 20 that is subjected to position adjustment and the support frame 15 and the drive device 30 that support the frame-shaped body 20 can be raised and lowered. Thus, the height of the frame-shaped body 20 described below can be adjusted so that the propeller of the frame-shaped body 20 can properly abut against the object.

[0070] Although not shown in the figure, the position adjustment device 1 may also include a base for placing an object in the central area 50. For example, the base may include a structure that can be raised and lowered along the Y direction. Thereby, the object placed on the base can be raised and lowered. For example, the height of the object relative to the frame body 20 described below can be adjusted so that the pusher of the frame body 20 can properly abut against the object. Such a structure may be particularly useful when stacking position-adjusted objects. For example, after stacking a new object on the position-adjusted object and adjusting the height of the object to an appropriate position by raising and lowering the base, the stacked objects are position-adjusted so that the position-adjusted objects can be stacked on the base.

[0071] (Support frame)

[0072] Figure 7 It is an exploded perspective view showing the support frame 15 and the frame-shaped body 20 according to one embodiment of the present disclosure. Figure 8A and Figure 8B 1 and 2 are a perspective view and a top view respectively schematically showing a support frame 15 involved in an embodiment of the present disclosure. The support frame 15 has an opening area 18 in the center. The object can be moved in a direction Y (for example, a vertical direction) that is approximately perpendicular to the extension direction (for example, a horizontal direction) of the opening area 18 through the opening area 18. The support frame 15 can be fixed to the arm 12 of the stand using a fixing member such as a nut. In addition, the support frame 15 has a shaft insertion hole 16, and the shaft portion 252 of the connecting member 250, which is a component of the frame-shaped body 20 described below, can be inserted into the shaft insertion hole 16. As shown in the figure, the shaft portion 252 of the connecting member 250 can be inserted into the shaft insertion hole 16 of the support frame 15 and fixed with a fixing member such as a nut, thereby installing the support frame 15 and the frame-shaped body 20.

[0073] (frame-shaped body)

[0074] Figure 9 It is an exploded three-dimensional view of a frame body involved in one embodiment of the present disclosure. The frame body 20 comprises at least: a central area 50, in which the object to be position-adjusted is placed; a plurality of rod members 220, which are arranged to surround the central area 50; and a plurality of thrusters 230, 240, which are mounted on the rod members 220. Two adjacent rod members 220 can be connected to each other. More specifically, the plurality of rod members 220 can be connected to each other by a connecting member 250 arranged between the ends 221 of the adjacent rod members 220. Hereinafter, the extension direction of the central area 50 is referred to as the ZX plane direction, and the direction perpendicular to the extension direction of the central area 50 is referred to as the Y direction. Preferably, the ZX plane direction is the horizontal direction, and the Y direction is the vertical direction.

[0075] The "central area of the frame" refers to the area surrounded by the rod member 220 and pushers 230 and 240 that constitute the frame 20 and that penetrates in the Y direction. Objects are placed in this central area 50 and their positions are adjusted within it. Therefore, this central area 50 may also be referred to as the "object placement area" or "position adjustment area." Within this central area 50, objects are pushed by the pushers, causing them to move and / or rotate on the same plane, thereby being adjusted to a desired position and / or posture.

[0076] (Rod member)

[0077] The rod member 220 is arranged to surround the central area 50. More specifically, the rod member 220 may be an elongated member extending along the outer contour of the central area 50. It may have an elongated shape (or a rod-like or strip-like shape) extending in a single direction parallel to the extension direction of the central area 50. While the rod member 220 may extend in a straight line, it does not necessarily have a uniform straight line and may, for example, have a partially curved or bent portion. The rod member 220 supports a propeller capable of pushing an object placed in the central area 50. Therefore, the rod member 220 may also be referred to as a "propeller support member."

[0078] In the position adjustment device of the present disclosure, the plurality of rod members 220 can be displaced in conjunction with each other. More specifically, the plurality of rod members 220 can be displaced in conjunction with each other and can be displaced in a direction approaching or separating from the center of the frame 20. Hereinafter, the position of the rod member 220 farthest from the center of the frame 20 is referred to as the first position (refer to Figure 2 ), and the position of the rod member closest to the center of the frame body 20 is referred to as the second position (refer to Figure 4 When the multiple rod members 220 are in the first position, the area of the central region 50 is the largest. On the other hand, when the multiple rod members 220 are in the second position, the area of the central region 50 is the smallest. The multiple rod members 220 can each be able to slide and move in conjunction with each other between a first position farther from the frame 20 and a second position closer to the frame 20. In other words, the displacement of the multiple rod members 220 can be synchronized with each other, thereby allowing the multiple rod members 220 surrounding the central region 50 to displace simultaneously.

[0079] (Thruster)

[0080] like Figure 9As shown, the position adjustment device 1 of the present disclosure includes a plurality of pushers 230, 240 mounted on a rod member 220. The pushers are configured to be able to push an object placed on the central area 50. In the position adjustment device 1 of the present disclosure, the plurality of rod members 220 and the plurality of pushers 230, 240 mounted on the rod member 220 can be displaced in a direction close to the object in a linked manner with each other. As a result, the central area 50 can be reduced in size and the object can be moved to a desired position. More specifically, the pushers 230, 240 are displaced in a direction close to the object placed on the central area 50 as the rod member 220 is displaced, and push the outer periphery of the object. Through this pushing, the object is horizontally moved to the desired position on the same plane as the central area 50.

[0081] At least two of the multiple pushers 230 and 240 are arranged opposite each other across the central region 50. These two pushers can be mounted on two rod members 220, each of which is arranged opposite each other across the central region 50. These pushers move toward the central region 50, approaching each other as the rod members 220 move. By arranging at least two pushers at opposing positions, an object can be pressed from multiple directions, sandwiching the object. This allows the object's position to be adjusted between the two pushers with respect to the pushing direction of the pushers.

[0082] In another embodiment, the position adjustment device 1 may include, in addition to the two pushers facing each other, a pusher capable of pushing the object in a direction different from that of the two pushers. For example, the position adjustment device 1 may include a pusher on each of the multiple rod members 220. This allows the object to be pushed from more directions, thereby enabling more precise adjustment of the object's position.

[0083] As described above, the plurality of pushers are attached to the plurality of rod members 220, respectively. Therefore, as the rod members 220 are displaced, the pushers 230 and 240 attached to the rod members 220 also displace. In the position adjustment device 1 of the present disclosure, the plurality of rod members 220 are configured to be displaced in conjunction with one another, thereby enabling the plurality of pushers 230 and 240 to be displaced in conjunction with one another. In other words, the plurality of pushers 230 and 240 do not displace independently, but rather are displaced synchronously with one another.

[0084] In one embodiment of the present disclosure, the position adjustment device 1 may include at least two types of pushers 230 and 240 having different structures. In other words, in the position adjustment device 1 of the present disclosure, the object can be positioned in the central area 50 of the frame 20 by using multiple pushers including different types of pushers 230 and 240 to push the object.

[0085] For example, the plurality of thrusters may include a reference thruster 230 and a driven thruster 240. The reference thruster 230 includes a roller 232 fixed so as to be displaceable only in association with the rod member 220. On the other hand, in the driven thruster 240, the roller 242 is elastically supported by an elastic member 246, so that the roller 242 can be displaced independently of the rod member 220. The position adjustment device of the present disclosure may include a plurality of thrusters including the reference thruster 230 and the driven thruster 240. The configuration of the reference thruster 230 and the driven thruster 240 will be described in more detail below.

[0086] (Baseline Thruster)

[0087] 10A to 10C 1 and 2 are perspective views, top views, and side views schematically illustrating a reference thruster according to an embodiment of the present disclosure. Figure 11 yes 10A to 10C Exploded perspective view of the reference pusher shown. As shown in the figure, the reference pusher 230 includes a roller 232 that can abut against the outer periphery of an object and a roller support portion 235 that supports the roller 232. The roller support portion 235 can be mounted on the rod member 220 and protrude toward the central area 50 of the frame 20. The roller 232 can be mounted on the end of the roller support portion 235 that protrudes toward the central area 50. Thus, the roller 232 is located closer to the inner peripheral side of the frame 20 than the rod member 220. With such a structure, when the pusher 230 is displaced toward the central side of the frame 20 as the rod member 220 is displaced, the reference pusher 230 can abut against the object placed in the central area 50 and push the object toward the displacement direction of the rod member 220.

[0088] The roller 232 can be fixed to the roller support 235 via a fixing member such as a nut. Similarly, the roller support 235 can be fixed to the rod member 220 via a fixing member such as a nut. Simply put, the roller 232 is fixed to the rod member 220 via the roller support 235. Thus, the roller 232 of the reference pusher 230 is fixed to the rod member 220 so that it cannot move independently. In other words, the reference pusher 230 can include a roller 232 that can only move due to displacement of the rod member 220. Therefore, the reference pusher 230 can also be referred to as a "fixed pusher."

[0089] In the reference pusher 230, since the roller 232 is fixed relative to the rod member 220 in a manner that does not move independently, the displacement of the roller 232 stops together with the stop of the rod member 220. As a result, the stop position of the roller 232 at the position where the rod member 220 stops can be used as the reference position of the object. In other words, the stop position of the roller 232 when the rod member 220 is in the second position closest to the center of the frame 20 is the reference position of the object. For example, when the rod member 220 moves in the direction of the object arranged in the central area 50, the reference position of the object can be determined by controlling the displacement of the rod member 220 so that the roller 232 of the reference pusher 230 stops at the desired position. In the position adjustment device 1 of the present disclosure, by making at least one of the two pushers opposite to each other across the central area 50 a reference pusher, the object can be pushed toward the reference pusher 230 by the other pusher. Through such a structure, the object can be stably aligned to the desired position.

[0090] The reference pusher 230 preferably includes at least two rollers 232. More specifically, the reference pusher 230 may include at least two rollers 232 located at the same height in the Y direction. That is, the at least two rollers 232 provided on the reference pusher 230 may be arranged in parallel along the extension direction of the central region. For example, the reference pusher 230 may include: Figure 10A The two rollers are arranged side by side as shown. The object contacting the reference pusher 230 can be supported at two points by contacting the two rollers 232. This two-point support determines the orientation of the object's edges, thereby maintaining the object's linearity. Consequently, the object's posture can be more appropriately maintained when subjected to the pushing (or pressing) force from the pusher positioned opposite the reference pusher 230.

[0091] (Driven propeller)

[0092] 12A to 12C 1 and 2 are perspective views, top views, and side views schematically illustrating a driven propeller according to an embodiment of the present disclosure. Figure 14 yes 12A to 12C The driven propeller 240 is different from the above-mentioned reference propeller 230 in that the roller support portion 245 of the support roller 242 includes an elastic member 246. In other words, the roller 242 of the driven propeller is elastically supported on the rod member 220 via the elastic member 246 provided in the roller support portion 245. The elastic member 246 is located between the roller 242 and the rod member 220. For example, it can be Figure 13As shown, the roller support portion 245 includes: a first roller support portion 245A, the roller 242 is mounted on the first roller support portion 245A; and a second roller support portion 245B, which is responsible for connecting the first roller support portion 245A and the rod member 220. An elastic member 246 is provided on the shaft 248 connecting the first roller support portion 245A and the second roller support portion 245B (see Figure 14 The elastic member 246 is not particularly limited as long as it can absorb the pressing force applied from the object to the roller 242. For example, a spring such as a coil spring or a rubber material can be used as the elastic member 246.

[0093] When a pushing force is applied to the elastic member 246 via the roller, the elastic member 246 can be compressed and elastically deformed. Due to this elastic deformation, the roller 242 can be displaced toward the rod member 220. More specifically, when a pushing force is applied to the roller 242 from an object, the elastic member 246 disposed between the roller 242 and the rod member 220 is compressed, and the roller 242 can be displaced in a direction closer to the rod member 220. For example, the first roller support portion 245A can be supported so as to be rotatable relative to the second roller support portion 245B about the fulcrum 247. According to this configuration, when the rod member is further displaced toward the second position while the roller 242 is in contact with the object, the elastic member can be compressed, and the first roller support portion can be rotated toward the rod member 220 about the fulcrum 247. As a result, the roller 242 is displaced so as to be pushed toward the rod member.

[0094] Thus, since the driven propeller 240 is configured to be able to push the roller 242 toward the rod member 220 using the elastic member 246, it can also be called a "movable propeller", "push-in propeller", etc. According to the above structure, even when the driven propeller 240 contacts the object as the rod member 220 is displaced, the impact on the object can be mitigated by the elastic member 246 being sandwiched therebetween. That is, the elastic member 246 provided in the roller support portion 245 can play the role of a buffer material. In addition, in the driven propeller 240, when a pushing force is applied to the driven propeller 240 from the object, the roller 242 can be displaced toward the rod member 220 together with the first roller support portion 245A due to the compression of the elastic member 246. As a result, it is possible to suppress the deviation of the adjustment position of the object due to the tolerance of the outer dimensions of the object.

[0095] For example, by setting the displacement of the driven pusher 240 caused by the displacement of the rod member 220 to the minimum value of the external dimensional tolerance, the object can be fully moved to the desired position even if its external dimensions are small. Furthermore, even if the object's external dimensions are large, the compression of the elastic member 246 can reduce the displacement of the driven pusher 240 to less than the displacement of the rod member 220. This prevents excessive pressure from being applied to the object, allowing for appropriate position adjustment. This effectively prevents damage to the object caused by excessive pressure from the driven pusher 246.

[0096] In a suitable embodiment, the reference pusher 230 and the driven pusher 240 may face each other across the central region 50. That is, one of the two opposing pushers may be the reference pusher 230, and the other may be the driven pusher 240. An object placed in the central region 50 can be positioned at a desired position in the central region 50 by being pressed from both sides of the object while being sandwiched between the reference pusher 230 and the driven pusher 240.

[0097] In a preferred embodiment, the driven propeller 240 includes a roller 242, and the reference propeller 230, which is mounted opposite the driven propeller 240, includes two rollers 232. The rollers 232, 242 of the reference propeller 230 and the driven propeller 240 are located at the same height with respect to the Y direction. When the object is positioned, the object preferably abuts at least both rollers 232 of the reference propeller 230, and more preferably abuts the rollers 232, 242 of all propellers 230 and 240. This allows the position and orientation of at least one edge of the object's outer periphery to be appropriately determined.

[0098] Furthermore, the reference pusher 230 and the driven pusher 240 can each be arranged so that the pushing force of the roller 242 of the driven pusher 240 on the object acts between the two rollers 232 of the reference pusher 230. Thus, the position of the object can be adjusted by clamping the object between the two opposing pushers, and unintended rotation of the object due to the pressure of one pusher can be avoided.

[0099] The pushing force applied to the object by the driven thruster 240 can be set to be smaller than the pushing force applied to the object by the reference thruster 230, which is arranged opposite the driven thruster 240. For example, the pushing force of the driven thruster 240 can be controlled to be lower than the pushing force of the reference thruster 230 through pressure control or torque control. This can mitigate the pushing force that may be applied to the reference thruster 230 by the object, and prevent the reference thruster 230 from moving unintentionally due to this pushing force. Consequently, it is possible to reduce deviations in the position of the object, which is adjusted based on the roller position of the reference thruster 230.

[0100] In addition, in one embodiment, the position adjustment device may have a plurality of reference thrusters 230. The plurality of reference thrusters 230 may be mounted on different rod members 220. The plurality of rod members 220 equipped with the reference thrusters 230 may extend in directions that intersect with each other. This means that the plurality of reference thrusters 230 are respectively mounted on rod members 220 that extend in different directions. Thus, the object can abut against the plurality of reference thrusters 230 that are displaced from multiple directions toward a direction close to the object. As described above, in the position adjustment device of the present disclosure, the object can be position-adjusted with the stop position of the reference thruster 230 that has been displaced toward the center of the frame 20 as the reference position. Therefore, when determining the position of the object, by having two reference thrusters 230, the position of the object can be determined with at least two sides of the outer periphery of the object as a reference. Thus, the position of the object in the central area 50 can be adjusted more precisely.

[0101] For example, Figure 9 As shown, the position adjustment device can include a reference propeller 230 installed on each of two rod members 220 extending in directions perpendicular to each other and a driven propeller 240 installed at a position opposite to each of the reference propellers 230. According to such a structure, the object can be pushed from four directions to adjust its position. Furthermore, by providing a reference propeller 230 on each of the two rod members 220 that are approximately perpendicular to each other, the position can be adjusted based on the two sides of the outer periphery of the object extending in directions perpendicular to each other. Furthermore, by installing the driven propeller 240 at a position opposite to the reference propeller 230, the position of the object can be adjusted more precisely on the reference propeller 230 side, while the external dimensional tolerance of the object can be addressed on the driven propeller 240 side. Therefore, according to such a structure, even for an object with deviations in external dimensions, the position can be accurately adjusted.

[0102] In addition, the roller of the propeller has a roller surface that contacts the object. The roller surface can be a curved surface such as an arc surface. For example, the roller can be a substantially spherical shape. Alternatively, as Figure 10C 、 Figure 12C and Figure 13 As shown, the rollers 232 and 242 may include a substantially cylindrical or columnar member at one end of the shaft portion, and the member may include a roller surface 233 and 243 that is a curved surface in a plan view.

[0103] In one embodiment, the roller surface can be tilted relative to the Y direction when viewed from the side. More specifically, the roller surface can be tilted so as to gradually approach the central region from the lower end to the upper end of the roller. That is, when viewed from the side, the lower region of the roller surface facing the central region can be located closer to the outer periphery of the frame-shaped body than the upper region of the roller surface. In other words, when viewed from the side, the upper end region of the roller surface can be located closer to the inner periphery of the frame-shaped body than the lower end region of the roller surface. With this structure, an object whose position is adjusted in the central region can abut only against the upper region without contacting the lower region of the roller surface. This reduces the contact area between the object and the roller. For example, the roller can be mounted on the roller support portion so that the shaft portion is tilted. Alternatively, the shaft portion can extend along the Y direction, while only the roller surface is tilted. For example, a roller with a roughly conical shape can be used.

[0104] For example, during the assembly process of objects or packaging for transportation, a position adjustment device may be used while the object is placed on a component to adjust the position of the object placed on the component. Alternatively, a position adjustment device may be used on stacked objects 80 to adjust the position of multiple objects while stacking them. Figure 13 2 is a side view schematically showing the contact between the stacked object 80 and the driven pusher 240. Figure 13 In the figure, a driven propeller 240 is shown as an example, but the same structure can also be used in the reference propeller. As shown in the figure, in order to adjust the position of an object 80 stacked on any object or an object 80a arranged on the top layer among a plurality of stacked objects 80, the position adjustment device of the present invention can be used. In such a case, it is necessary to move only the object 80a to be adjusted in position to the desired position by the propeller 240. In the position adjustment device of the present invention, by providing the propeller 240 with a roller surface 243 that is tilted when viewed from the side, only the upper area 243a of the roller surface that is closer to the inner peripheral side of the frame-shaped body can abut against the object 80a to be adjusted in position. Specifically, the roller surface 243 that is tilted when viewed from the side can maintain a non-contact state with the article 80b below the object while selectively contacting only the object to be adjusted in position.

[0105] Furthermore, in the above-described embodiment, the inclined roller surface 243, when viewed from the side, is tilted so as to separate from the object 80b located below the object 80a being positioned. This effectively prevents the object 80b located below the object 80a from contacting the roller 242 and causing the unintended movement of objects 80b other than the object 80a. For example, if the object 80b located below the object 80a has a larger width than the object 80a, there is a concern that the object 80b may be caught by the roller when it enters the lower end of the roller 242, causing the positioning device to malfunction. According to the structure of the present disclosure described above, since the roller 242 is fixed so as to tilt from the top end to the bottom end in a direction away from the central region, the lower end of the roller 242 can be further separated from the object 80b located below the object 80a. Thus, it is possible to more appropriately prevent the roller 242 from accidentally contacting an object 80b other than the object 80a, and the object 80b from being caught by the roller due to such contact. By using the inclined roller surface 243, the contact area between the roller 242 and the object 80a can be reduced. Therefore, even when the thickness of the object 80a is small, it is possible to selectively adjust the position of only the object 80a, and the above-mentioned configuration may be particularly useful. The position adjustment device disclosed herein can appropriately adjust the position of an object having a thickness of, for example, approximately 0.1 mm or more and approximately 10 mm or less.

[0106] In a suitable embodiment, at least the roller 242 of the driven propeller 240 has a roller surface 243 inclined with respect to the Y direction. For example, the roller 242 of the driven propeller 240 may have an inclined roller surface 243, while on the other hand, Figure 10D As shown, the roller surface 233 of the roller 232 of the reference pusher 230 extends approximately parallel to the Y direction (i.e., approximately perpendicular to the central region's extension direction, i.e., the ZX plane). This makes it possible to prevent the roller 242 of the driven pusher 240 from seizing, while also ensuring that the object properly contacts the roller 232 of the reference pusher 230 after position adjustment, accurately placing the object in the desired position. Alternatively, all the pusher rollers may have inclined roller surfaces. This structure may be more suitable for positioning the top layer of multiple stacked objects, as it can appropriately prevent the rollers of each pusher from seizing.

[0107] The inclination angle of the inclined roller surfaces 233 and 243 is not particularly limited as long as only the upper end region of the roller can contact the object. For example, when viewed from the side, the angle α formed by the Y direction (i.e., the direction perpendicular to the extension direction of the central region) and the roller surface is Figure 10C and Figure 12C) can be greater than 0 degrees and less than 60 degrees, greater than 1 degree and less than 50 degrees, or greater than 3 degrees and less than 45 degrees. By setting the roller surface inclination angle α within the above range, the roller can be properly positioned so that it contacts only the topmost object of a stack of multiple objects, while maintaining a non-contact state with objects in lower layers. The roller surfaces of the multiple pushers can have the same inclination angle, or each pusher can have a different inclination angle.

[0108] (Connecting components)

[0109] like Figure 7 As shown, the plurality of rod members 220 may be coupled to each other via a coupling member 250 . Figures 15A to 15C 1 and 2 are perspective views, top views, and side views schematically illustrating a connecting member 250 according to an embodiment of the present disclosure. The connecting member 250 can connect the ends 221 of the adjacent rod members 220 to each other (see FIG. Figure 9 ). In other words, adjacent rod members 220 can be connected end-to-end via a connecting member 250. The skeleton of the frame-shaped body can be formed by connecting all the rod members 220 in a ring shape using the connecting member 250. By connecting the multiple rod members 220 in this way, the multiple rod members 220 can be properly linked, and the multiple thrusters 230, 240 installed on the rod members 220 can also be properly linked. In this way, it is possible to provide an appropriate position adjustment device in which the displacements of the multiple thrusters 230, 240 are synchronized with each other and position adjustment with smaller deviation can be performed.

[0110] like Figures 15A to 15C As shown, the connecting member 250 includes two connecting rods 254 connected to two adjacent rod members 220, and a shaft 252 provided between the two connecting rods 254. The shaft 252 is located closer to the inner circumference of the frame 20 than the connecting rods 254. In other words, the connecting rods 254 are located farther from the central area 50 than the shaft 252. The shaft 252 of the connecting member 250 can be inserted into the shaft insertion hole 16 formed on the support frame 15 (see FIG. Figure 7 ). The connecting member 250 is supported by the supporting frame 15 so as to be rotatable with the shaft portion 252 as the rotation axis. In addition, the rod member 220 can be connected so as to be rotatable with the connecting rod portion 254 as the axis. In such a structure, when the connecting member 250 rotates, the rod members 220 connected by the connecting rod portion 254 can be displaced in conjunction with each other. More specifically, since a plurality of rod members 220 are connected to each other via the connecting member 250, when one connecting member 250 rotates, the rod members 220 directly or indirectly connected to the connecting member 250 and the other connecting members 250 can all be displaced or rotated in conjunction with each other (refer to Figure 3 and Figure 4 ).

[0111] The distance from the shaft portion 252 of the connecting member 250 to each of the two connecting rod portions 254 can be arbitrarily set according to the movement distance of the rod member 220 connected to the connecting member 250. The "distance from the shaft portion 252 to the connecting rod portion 254" is equivalent to the distance from the center of the shaft portion 252 to the center of the connecting rod portion 254 when viewed from above. For example, the longer the distance from the shaft portion 252 to the connecting rod portion 254, the greater the movement of the rod member 220 caused by the rotation of the connecting member 250. This means that the movable range of the rod member 220 and the thrusters 230 and 240 can be further increased. In this way, the position adjustment device of the present disclosure can cope with the position adjustment of objects of various sizes by arbitrarily setting the distance from the shaft portion 252 of the connecting member 250 to the connecting rod portion 254.

[0112] In addition, when the distance from the shaft portion 252 to the connecting rod portion 254 is further extended, the central area 50 before position adjustment can be ensured to be wider, so the area on which the object before position adjustment can be placed can be further increased. In the case where the central area 50 before position adjustment is narrow, when the object is placed in the central area, it is necessary to align the orientation of the object to a certain extent. Such a situation may be particularly significant when position adjustment is performed on an object with a large dimensional tolerance. On the other hand, when the central area 50 before position adjustment is wide, the degree of freedom of the posture of the object placed in the central area before position adjustment becomes higher. In the position adjustment device of the present disclosure, by arbitrarily setting the distance from the shaft portion 252 of the connecting member 250 to the connecting rod portion 254, position adjustment can be appropriately performed even for an object with a large dimensional tolerance.

[0113] In the two connecting members 250 mounted on the respective ends 221 of one rod member 220, the distances D1 and D3 from the shaft portion 252 to the link portion 254 connected to the rod member 220 may be equal to each other (see Figure 19 More specifically, the distance D1 between the shaft portion 252 and the link portion 254 of the connecting member 250 attached to one end portion 221 of the rod member 220 may be equal to the distance D2 between the shaft portion 252 and the link portion 254 of the connecting member 250 attached to the other end portion 221. This allows the two ends 221 of the rod member 220 to move the same amount, allowing the rod member 220 to move parallel to or away from the object.

[0114] In one embodiment, the distances D1 and D2 from the center of the shaft portion 252 to the centers of the two connecting rod portions 254 can be equal. This allows the ends 221 of the rod members 220 connected to the two connecting rod portions 254 to move the same distance at the same speed. Alternatively, in a single connecting member 250, the distances D1 and D2 from the two connecting rod portions 254 connected to the two rod members 220 to the shaft portion 252 can be different. That is, in a single connecting member 250 connecting two adjacent rod members 220, the distance D1 from the connecting rod portion 254 connected to one rod member 220 to the shaft portion 252 can be different from the distance D2 from the connecting rod portion 254 connected to the other rod member 220 to the shaft portion 252. This allows each rod member 220 to move a different distance as the connecting member 250 rotates. Therefore, by arbitrarily setting the distance from the shaft portion 252 of the connecting member 250 to the link portion 254 , it is possible to perform position adjustment on objects of various shapes.

[0115] (Drive equipment)

[0116] The position adjustment device of the present disclosure further includes a driving device 30 for displacing the rod member 220 of the frame body 20 . Figure 16 and Figure 17 3D diagram showing a driving device according to an embodiment of the present disclosure before and after operation. As shown in the figure, the driving device 30 includes a cylinder mechanism capable of reciprocating motion. More specifically, the driving device 30 may include a rod member 32 and a connecting portion 34 connecting the front end of the rod member 32 and the rod member 220. The rod member 32 may be capable of moving forward and backward in the displacement direction of the rod member 220. The driving device 30 may be a device having any of various mechanisms such as an air cylinder, a hydraulic cylinder, an electric cylinder, or a combination of a motor and a ball screw or a timing belt configured to cause the rod member 32 to reciprocate linearly. The driving device 30 displaces the rod member 220 in a direction of approaching or separating from an object through the reciprocating motion of the rod member 32. For example, as Figures 1 to 4 As shown, the driving device 30 may be connected to one of the plurality of rod members 220 constituting the frame 20. In a suitable embodiment, the rod member 220 to which the driving device 30 is attached may be a rod member 220 having a reference pusher 230.

[0117] The driving device 30 causes a rod member 220 to reciprocate in a direction toward or away from an object. More specifically, the driving device 30 may be capable of pushing or pulling the rod member 220 in the direction of rotation of the connecting member 250. Therefore, the extension direction of the rod member 220 and the reciprocating direction of the cylinder mechanism of the driving device 30 may intersect each other at an angle. This means that the extension direction of the rod member 220 and the reciprocating direction of the cylinder mechanism of the driving device do not intersect each other perpendicularly. With such a structure, the driving device 30 can indirectly rotate the connecting member 250 connected to the rod member 220 by causing the rod member 220 to reciprocate. As the connecting member 250 rotates, the rod members 220 connected to each other via the connecting member 250 can be displaced synchronously with each other. In this way, by using the driving device 30 to displace one rod member 220, multiple other rod members 220 can be displaced in a coordinated manner.

[0118] Next, the operation of the position adjusting device 1 having the above-described configuration will be described. Figure 18 and Figure 19 1 are schematic perspective and top views of the position adjustment device 1 before position adjustment. As shown in the figure, with multiple rod members 220 in the first position, the object 80 is placed in the central area 50. Driven by the drive device 30, the rod member 220 connected to the drive device 30 is pushed and moved toward the inner circumference of the frame. As the rod member 220 moves, the connecting member 250 connected to the rod member 220 rotates, and all rod members 220 connected by the connecting member 250 are displaced. More specifically, when the rod member 220 is pushed by the drive device 30, the connecting member 250 connected to the rod member 220 rotates about the shaft 252 as the rotation axis. Through this rotation, the other rod members 220 connected to the connecting member 250 are displaced. Thus, by causing one rod member 220 to be displaced by the drive device 30, all other rod members 220 can be displaced simultaneously.

[0119] In this configuration, the multiple connecting members 250 located between the multiple rod members 220 rotate in the same direction. This allows all of the multiple rod members 220 to be displaced from the first position to the second position in a coordinated manner. In other words, all of the multiple rod members 220 are displaced toward the object 80. The multiple pushers 230 and 240 attached to the rod members 220 are also displaced in a coordinated manner toward the object 80.

[0120] The plurality of pushers 230 and 240 that are displaced in conjunction with each other come into contact with the outer peripheral edge 81 of the object 80 , and move the object 80 while pushing it. Figure 20 and Figure 21The figures are a perspective view and a top view, respectively, schematically illustrating the position adjustment device 1 after position adjustment. When the plurality of lever members 220 reach the second position, the object 80 can be pushed toward the reference pusher 230 by the elastic member of the driven pusher 240. This allows the object 80 to be more accurately positioned relative to the roller of the reference pusher 230.

[0121] When viewed from above, the movement trajectory of the rod member 220 between the first position and the second position may not be a straight line. Figure 19 ) moves to the second position ( Figure 21 ), the two ends of the rod member 220 are respectively displaced from the first position to the second position along an arc-shaped trajectory, with the shaft portion of the connecting member 250 connected to each end as the rotation axis. In this way, the rod member 220 can be displaced not along a straight trajectory, but along a curved track. Similarly, the pushers 230, 240 fixed to the rod member 220 can also be displaced between the first position and the second position along the arc-shaped track. The pushers 230, 240 can move the object 80 placed on the central area 50 in a manner that rotates within the plane of the central area 50. That is, when adjusting the position of the object 80, the pushers 230, 240 can push in the direction of assisting the object 80 to rotate within the plane extending in the central area 50, so that the object can be more appropriately adjusted to the desired posture (orientation).

[0122] Furthermore, by enabling pushers 230 and 240 to move from the first position to the second position along an arcuate trajectory, the direction of the pushing force exerted by pushers 230 and 240 on object 80 is in a direction that is obliquely intersecting with the extension direction of rod member 220 to which pushers 230 and 240 are attached. Furthermore, by enabling displacement along an arcuate trajectory, the direction of the pushing force acting on object 80 can change during the displacement from the first position to the second position. This allows for more appropriate dispersion of the pushing force that may be exerted on object 80, compared to a case where pushers 230 and 240 are linearly displaced in a direction perpendicular to the extension direction of rod member 220. Consequently, it is possible to appropriately prevent excessive pushing force from acting on object 80 during position adjustment.

[0123] In the connecting member 250 connected to each end of the rod member 220, the distance D1 from the connecting rod connected to one end to the shaft portion and the distance D3 from the connecting rod connected to the other end to the shaft portion are equal. This allows the rod member 220 to slide along an arc-shaped track while maintaining its tilt. This allows the position of the object 80 to be adjusted while maintaining the tilt of the pushers 230 and 240 attached to the rod member 220 when viewed from above. In particular, in a reference pusher 230 having two or more rollers, the tilt of the object 80 is determined based on its tilt. Therefore, the position adjustment device of the present disclosure, which can move while maintaining the pusher's tilt, can more accurately adjust the posture of the object. Furthermore, the two rod members 220, each having pushers facing each other across the central region 50, can be displaced from a first position to a second position while maintaining a parallel relationship. The two opposing pushers can approach the object while maintaining their angular relationship, appropriately guiding the object to a desired position.

[0124] After the position adjustment, when the drive device 30 is driven in the direction of retracting the rod member 220, the rod members 220 are displaced in conjunction with each other, causing the multiple rod members 220 to move in a coordinated manner from the second position to the first position. This causes the multiple pushers 230 and 240 in contact with the object 80 to retract from the object 80. Since the multiple rod members 220 are in a coordinated manner, the retraction of the multiple pushers 230 and 240 can also be coordinated. This effectively prevents any positional shifts in the object 80 caused by misaligned movement timing of some pushers.

[0125] As described above, according to the present disclosure, it is possible to use one drive source to implement position adjustment of the object 80 from multiple directions. As a result, the device structure can be made simpler. In addition, by using one drive source, the energy required for the device to work becomes smaller, so the position adjustment can be performed more efficiently. In addition, for example, when different drive devices are used to control the movement of the propeller from multiple directions, there is a concern that the movement timing and displacement of each propeller will deviate and the position of the adjusted object will deviate. In the position adjustment device of the present disclosure, since the position adjustment from multiple directions can be linked, the movement timing and displacement of multiple propellers can be appropriately synchronized. As a result, the position adjustment of the object can be performed more stably and accurately. In this way, according to the present disclosure, a more appropriate position adjustment device capable of performing position adjustment from multiple directions is provided.

[0126] As an object to be position-adjusted using the position adjustment device of the present invention, various components having an outer peripheral edge that can be abutted and pushed by the roller of the pusher can be listed. For example, the object can be a polyhedron such as a cuboid or a cube, or a roughly plate-shaped component. In this specification, "roughly plate-shaped" may not necessarily mean a completely flat plate. For example, it may be a shape having steps or protrusions in part, or a shape having a portion that is curved when viewed from the side. The shape of the object when viewed from above may be various shapes such as a roughly circular shape, an elliptical shape, a polygonal shape, etc., having an outer peripheral edge that can be abutted by the roller in the second position.

[0127] The thickness of the object is not particularly limited, and may be, for example, 0.1 mm or more, 0.3 mm or more, or 0.5 mm or more. In addition, the upper limit is not particularly limited as long as the object can be moved by the pressure from the pusher.

[0128] While the embodiments of the present invention have been described above, these are merely typical examples, and those skilled in the art will readily appreciate that the present invention is not limited thereto, and that various alternatives are contemplated without departing from the spirit of the present invention.

[0129] The above-mentioned effects are merely exemplary. Therefore, the present invention is not limited to the above-mentioned matters, and may also have additional effects.
