Description

rotary conveyor

[0001] This application claims the benefit of priority from Republic of Korea Patent Application No. 10-2024-0017547, dated February 5, 2024, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a rotary transport device, which can be easily implemented at low cost with a simple configuration, and which is easy to manufacture and maintain even when the number of rotary transport parts increases, reduces manufacturing and maintenance costs, improves usability and compatibility, allows precise control of the rotation angle, and reduces movement and rotation errors.

[0003] When manufacturing secondary batteries, it is necessary to rotate and transport the process materials to an optimal state suitable for the assembly work of the next process.

[0004] An example of such a battery transport device is disclosed in Patent Registration No. 10-1764668 (Rotary transport device for battery components).

[0005] Referring to FIGS. 1 and 2, the battery transport device of this prior art may include a rotating part (110) and a plurality of process material rotating transport parts (130).

[0006] The rotating part (110) may be composed of a rotating shaft (111) and upper and lower rotating discs (112-1, 112-2). The rotating shaft (111) may be installed vertically and rotated. The upper and lower rotating discs (112-1, 112-2) may be installed at a predetermined distance above and below the upper end of the rotating shaft (111) so as to rotate together with the rotating shaft (111).

[0007] A plurality of process material rotation transport units (130) can be installed at regular intervals along the upper rotation plate (112-1) so as to rotate together with the upper and lower rotation plates (112-1, 112-2). In addition, a plurality of process material rotation transport units (130) can be rotated by the driving force transmitted from the rotation shaft (111) to transport the process materials received and supported in the process material receiving units by turning them to a 90 degree or 180 degree position suitable for the next process.

[0008] Each process material rotation conveyor (130) may include a cylindrical cam (131), a rack gear (132-2), and a process material support member (135).

[0009] The cylindrical cam (131) is installed integrally with the rotation axis (111) so as to rotate along the rotation axis (111) and may have a curved cam surface.

[0010] The rack gear (132-2) can be installed vertically so as to be able to move up and down by penetrating the upper and lower rotary discs (112-1, 112-2). The lower end of the rack gear (132-2) can be brought into rolling contact so as to move along the curved cam surface of the cylindrical cam (131). The upper end of the rack gear (132-2) can be installed so as to protrude from the upper rotary disc (112-1).

[0011] The pinion gear (133) can be rotatably supported within a support casing (134) that is fixedly supported on the upper rotating disc (112-1). The pinion gear (133) can be meshed with the rack gear (132-2).

[0012] The process material support member (135) can be installed to rotate integrally with the pinion gear (133). A process material receiving portion can be installed in the process material support member (135).

[0013] However, in such prior art, the cylindrical cam (131) is a vertical cam structure formed along the outer surface of the rotation shaft (111). Generally, since other devices are also installed on the rotation shaft (111), if the cylindrical cam (131) is installed on the outer surface of the rotation shaft (111), maintenance of the rotation transport device (100) is difficult and may interfere with other devices. In addition, if the number of process material rotation transport parts (130) increases, a plurality of rack gears (132-2) are densely arranged surrounding the rotation shaft (111), making maintenance difficult.

[0014] Prior art related to this is Korean Patent No. 10-1764668.

[0015] The present invention has been devised to solve the above-described problems, and aims to provide a rotary transport device that can be easily implemented at low cost with a simple configuration.

[0016] The purpose of the present invention is to provide a rotary conveying device that is easy to manufacture and maintain and reduces manufacturing and maintenance costs.

[0017] The purpose of the present invention is to provide a rotary conveying device with improved usability and compatibility.

[0018] The purpose of the present invention is to provide a rotary conveying device that is easy to manufacture and maintain even when the number of rotary conveying parts increases.

[0019] The purpose of the present invention is to provide a rotary conveying device with improved structural stability and durability.

[0020] The purpose of the present invention is to provide a rotary transport device capable of precisely controlling a rotation angle and reducing movement error and rotation error.

[0045] In one embodiment, the displacement means (700) may include a cam member (710) that is fixed or rotates at a different speed than the rotary plate (500).

[0046] The cam member (710) can move each moving member (610) of each of the one or more rotary transfer parts (600) to one side or the other in the radial direction when the moving member (610) rotates together with the rotary plate (500).

[0089] According to embodiments of the present invention, a rotary transport device (50) comprises: a rotary plate (500) that rotates around a virtual first rotation axis (A1); a movable member (610) that is installed on the rotary plate (500) and rotates together with the rotary plate (500), and is movable to one side or the other in the radial direction around the first rotation axis (A1) on the rotary plate (500), a rotary member (620) that is installed on the rotary plate (500) to rotate around a virtual second rotation axis (A2) that extends in a direction intersecting the first rotation axis (A1), and a rotation conversion means (630) that converts movement of the movable member (610) into rotation of the rotary member (620); And each of the moving members (610) of the one or more rotary transfer units (600) may include a displacement means (700) that moves each moving member (610) to one side or the other in the radial direction when the moving member (610) rotates together with the rotary plate (500).

[0090] Accordingly, the rotary transport device (50) may include a rotary plate (500), one or more rotary transport parts (600), and a displacement means (700). Accordingly, the rotary transport device (50) can be easily implemented at low cost with a simple configuration.

[0091] In addition, unlike in the past, since the rotation conversion means (630) and displacement means (700) of one or more rotary transport units (600) can be installed on a rotary plate (500) with a large diameter rather than a rotary shaft with a small diameter, the manufacturing and maintenance of the rotary transport device (50) can be facilitated, and the manufacturing and maintenance costs of the rotary transport device (50) can be reduced. In particular, even if the number of rotary transport units (600) increases, the manufacturing and maintenance of the rotary transport device (50) can be facilitated.

[0092] In addition, since the moving member (610) and the like are installed on the rotary plate (500), the rotary transport device (50) may not be installed on the rotary axis (shaft) that rotates the rotary plate (500). Accordingly, the rotary transport device (50) can be installed and used without interference with other devices that utilize the rotary axis (shaft). In other words, the usability and compatibility of the rotary transport device (50) can be improved.

[0093] In addition, since the moving member (610) of each rotary transport unit (600) moves to one side or the other in the radial direction rather than in the axial direction of the first rotary shaft (A1), the rotary conversion means (630) of each rotary transport unit (600) can be radially arranged in the radial direction (e.g., centrifugal direction) rather than in the axial direction of the first rotary shaft (A1). Accordingly, the distance between the rotary conversion means (630) of the rotary transport units (600) adjacent to each other in the circumferential direction can increase, so that the manufacturing and maintenance of the rotary transport device (50) can be facilitated, and the manufacturing and maintenance costs of the rotary transport device (50) can be reduced. In particular, even if the number of rotary transport units (600) increases, the manufacturing and maintenance of the rotary transport device (50) can be facilitated.

[0094] According to embodiments of the present invention, the extension direction of the second rotation axis (A2) may be perpendicular to the first rotation axis (A1). The moving member (610) may move to one side or the other in the radial direction, but may move in a direction parallel to the second rotation axis (A2).

[0095] Accordingly, the structural stability and durability of the rotary transport device (50) are improved, and the rotation angle of the rotary member (620) according to the movement of the movable member (610) can be precisely controlled.

[0096] According to embodiments of the present invention, the second rotation axis (A2) can meet the first rotation axis (A1). The moving member (610) can move in the radial direction.

[0097] Accordingly, the structural stability and durability of the rotary transport device (50) are improved, and the rotation angle of the rotary member (620) according to the movement of the movable member (610) can be precisely controlled.

[0098] According to embodiments of the present invention, the rotation conversion means (630) may include a ball screw bolt (632) that is coupled to the moving member (610) and moves in one or the other direction in the radial direction together with the moving member (610) and has a screw thread formed on the outer circumference thereof, a ball screw nut (634) that is screw-connected to the ball screw bolt (632) and coupled to the rotating member (620), and a first support member (636) that is coupled to the rotating plate (500) and supports the ball screw nut (634) so ​​that the ball screw nut (634) can rotate. When the ball screw bolt (632) moves to one side or the other side in the radial direction together with the moving member (610), the ball screw nut (634) rotates around the second rotation axis (A2) along the screw thread, and the rotating member (620) can rotate together with the ball screw nut (634).

[0099] Accordingly, the rotation conversion means (630) can be easily implemented at low cost with a simple configuration. In addition, since the rotation angle of the rotation member (620) is proportional to the pitch of the screw thread of the ball screw bolt (632), the rotation angle of the rotation member (620) can be precisely adjusted according to the movement of the movable member (610). In addition, since the ball screw bolt (632) moves on the rotation axis of the rotation member (620), the structural stability and durability of the rotation transfer device (50) are improved, and the rotation angle of the rotation member (620) according to the movement of the movable member (610) can be precisely adjusted.

[0100] According to embodiments of the present invention, the displacement means (700) may include a cam member (710) that is fixed or rotates at a different speed from the rotary plate (500). The cam member (710) may move each of the moving members (610) of the one or more rotary transfer parts (600) to one side or the other in the radial direction when the moving members (610) of each of the one or more rotary transfer parts (600) rotate together with the rotary plate (500).

[0101] Accordingly, the displacement means (700) can be easily implemented at low cost with a simple configuration.

[0102] According to embodiments of the present invention, the cam member (710) may be installed on the rotary plate (500) or adjacent to the rotary plate (500) and may include a cam groove (712) into which the moving member (610) is inserted. The cam groove (712) has a distance from the first rotation axis (A1) that varies depending on the angular position with respect to the first rotation axis (A1), and accordingly, when the moving member (610) of each of the one or more rotary transfer parts (600) rotates together with the rotary plate (500), each moving member (610) may be moved to one side or the other side in the radial direction.

[0103] Accordingly, the displacement means (700) can be easily implemented at low cost with a simple configuration.

[0104] According to embodiments of the present invention, the cam home (712) may have a circular shape eccentric from the first rotation axis (A1).

[0105] Accordingly, the rotation cycle of the rotating plate (500) for the cam member (710) and the rotation cycle of the rotating member (620) can correspond.

[0106] According to embodiments of the present invention, the first rotation axis (A1) may extend in the vertical direction. The one or more rotation transfer parts (600) and the cam member (710) may be installed on the upper portion of the rotation plate (500). The cam groove (712) may be formed on the upper surface of the cam member (710).

[0107] Accordingly, the stability and durability of the rotary transport device (50) can be improved.

[0108] According to embodiments of the present invention, each of the rotary transport parts (600) may include an elastic member (640) that presses the moving member (610) toward one or the other side in the radial direction so that the moving member (610) is in close contact with the cam member (710).

[0109] Accordingly, the movable member (610) can move in close contact with the shape or outline of a predetermined portion (e.g., cam groove) of the cam member (710). Accordingly, the movement error of the movable member (610) in the radial direction to one side or the other is reduced, and accordingly, the rotation error of the rotating member (620) can be reduced, and the rotation angle of the rotating member (620) can be precisely adjusted.

[0110] According to embodiments of the present invention, the rotation conversion means (630) may include a ball screw bolt (632) that is coupled to the moving member (610) and moves in one or the other direction in the radial direction together with the moving member (610) and has a screw thread formed on the outer circumference thereof, a ball screw nut (634) that is screw-connected to the ball screw bolt (632) and coupled to the rotating member (620), and a first support member (636) that is coupled to the rotating plate (500) and supports the ball screw nut (634) so ​​that the ball screw nut (634) can rotate. When the ball screw bolt (632) moves to one side or the other side in the radial direction together with the moving member (610), the ball screw nut (634) rotates around the second rotation axis (A2) along the screw thread, and the rotating member (620) can rotate together with the ball screw nut (634). The elastic member (640) can be arranged between the moving member (610) and the first support member (636).

[0111] Accordingly, a rotary transport device (50) can be implemented with a simple configuration that reduces the movement error of the movable member (610) and the rotation error of the rotary member (620).

[0112] According to embodiments of the present invention, the displacement means (700) may include one or more guide surfaces (736) that rotate together with the rotary plate (500). Each of the guide surfaces (736) may extend to one or the other side in the radial direction and guide movement of the moving member (610) of each of the one or more rotary transfer units (600) to one or the other side in the radial direction.

[0113] Accordingly, the stability and durability of the rotary transport device (50) can be improved.

[0114] According to embodiments of the present invention, each of the guide surfaces (736) may be capable of pressing the moving member (610) of each of the one or more rotary transfer parts (600) in a circumferential direction surrounding the first rotation axis (A1).

[0115] Accordingly, the stability and durability of the rotary transport device (50) can be improved.

[0116] According to embodiments of the present invention, the displacement means (700) may include a ring-shaped second support member (730) installed on the rotary plate (500) and rotating together with the rotary plate (500). The second support member (730) may include one or more guide surfaces (736).

[0117] Accordingly, one or more guide surfaces (736) can be easily implemented at low cost with a simple configuration.

[0118] According to embodiments of the present invention, the displacement means (700) may include a cam member (710) that is fixed or rotates at a different speed from the rotary plate (500). The cam member (710) may move each of the moving members (610) of the one or more rotary transfer parts (600) to one side or the other in the radial direction when the moving members (610) of each of the one or more rotary transfer parts (600) rotate together with the rotary plate (500). The cam member (710) may be installed on the rotary plate (500) or adjacent to the rotary plate (500) and may include a cam groove (712) into which the moving members (610) are inserted. The cam groove (712) has a different distance from the first rotation axis (A1) depending on the angular position centered on the first rotation axis (A1), and accordingly, when each of the moving members (610) of the one or more rotation transfer units (600) rotates together with the rotary plate (500), each of the moving members (610) can be moved to one side or the other in the radial direction. The first rotation axis (A1) can extend in the vertical direction. The one or more rotation transfer units (600) and the cam member (710) can be installed on the upper portion of the rotary plate (500). The cam groove (712) can be formed on the upper surface of the cam member (710). The second support member (730) may include a support member (732) positioned radially outer than the cam member (710) and a cover member (734) formed to extend radially inward from the support member (732) and positioned on top of the cam groove (712) and configured to include one or more guide surfaces (736).

[0119] Accordingly, a displacement means (700) including a second support member (730) can be easily implemented at low cost with a simple configuration. In addition, the stability and durability of the rotary transport device (50) can be improved.

[0148]

[0149] [Rotary conveyor]

[0150] Referring to FIG. 3, a rotary transport device (50) according to one embodiment may include a rotary plate (500), one or more rotary transport parts (600), and a displacement means (700).

[0151] The turntable (500) can rotate around a virtual first rotation axis (A1). The first rotation axis (A1) can extend in the vertical direction.

[0152] One or more rotary transport units (600) may be installed on the turntable (500). One or more rotary transport units (600) may be installed on the upper portion of the turntable (500). One or more rotary transport units (600) may rotate together with the turntable (500).

[0153] Each rotary transport unit (600) may include a moving member (610), a rotating member (620), and a rotation conversion means (630). Each rotary transport unit (600) may include an elastic member (640).

[0154] In each rotary transport unit (600), the moving member (610), the rotary conversion means (630), and the rotary member (620) can be arranged in order from the radially inner side to the outer side.

[0155] The movable member (610) is installed on the rotary plate (500) and can be installed to be movable to one or the other side in the radial direction centered on the first rotation axis (A1). The radial direction (hereinafter, radial direction) centered on the first rotation axis (A1) can be a direction that moves closer to or away from the first rotation axis (A1) along a straight line passing through the first rotation axis (A1) on a plane perpendicular to the first rotation axis (A1).

[0156] When the extension direction of the second rotation axis (A2) described later is perpendicular to the first rotation axis (A1), the moving member (610) can move to one side or the other in the radial direction, but can move in a direction parallel to the second rotation axis (A2).

[0157] Accordingly, the structural stability and durability of the rotary transport device (50) are improved, and the rotation angle of the rotary member (620) according to the movement of the movable member (610) can be precisely controlled.

[0158] When the extension direction of the second rotation axis (A2) is perpendicular to the first rotation axis (A1) and the second rotation axis (A2) meets the first rotation axis (A1), the moving member (610) can move in the radial direction.

[0159] Accordingly, the structural stability and durability of the rotary transport device (50) are improved, and the rotation angle of the rotary member (620) according to the movement of the movable member (610) can be precisely controlled.

[0160] The rotating member (620) is installed on the rotating plate (500) and can be installed to rotate around a virtual second rotation axis (A2) extending in a direction intersecting the first rotation axis (A1).

[0161] The extension direction of the second rotation axis (A2) may be perpendicular to the first rotation axis (A1). At this time, the second rotation axis (A2) may meet the first rotation axis (A1). That is, the extension direction of the second rotation axis (A2) may be in the radial direction.

[0162] A rotational transport object can be installed on the rotational member (620). The rotational member (620) can fix the rotational transport object. The rotational member (620) can rotate the rotational transport object around the second rotational axis (A2).

[0163]

[0164] [Rotation conversion means]

[0165] The rotation conversion means (630) can convert the movement of the movable member (610) into the rotation of the rotary member (620).

[0166] The rotation conversion means (630) may include a ball screw bolt (632), a ball screw nut (634), and a first support member (636). The rotation conversion means (630) may include a coupler (638).

[0167] The ball screw bolt (632) can be coupled with the movable member (610). The ball screw bolt (632) can move radially to one side or the other side together with the movable member (610). The ball screw bolt (632) can have threads formed on the outer surface.

[0168] The ball screw nut (634) can be screw-connected with the ball screw bolt (632). The ball screw nut (634) can be coupled with the rotating member (620).

[0169] The first support member (636) can be combined with the rotary plate (500). The first support member (636) can support the ball screw nut (634) so ​​that the ball screw nut (634) can rotate.

[0170] When the ball screw bolt (632) moves radially to one side or the other side together with the moving member (610), the ball screw nut (634) can rotate around the second rotation axis (A2) along the screw thread. Accordingly, the rotating member (620) can rotate together with the ball screw nut (634).

[0171] Accordingly, the rotation conversion means (630) can be easily implemented at low cost with a simple configuration. In addition, since the rotation angle of the rotation member (620) is proportional to the pitch of the screw thread of the ball screw bolt (632), the rotation angle of the rotation member (620) can be precisely adjusted according to the movement of the movable member (610). In addition, since the ball screw bolt (632) moves on the rotation axis of the rotation member (620), the structural stability and durability of the rotation transfer device (50) are improved, and the rotation angle of the rotation member (620) according to the movement of the movable member (610) can be precisely adjusted.

[0172] The first support member (636) may include a support member (637). The support member (637) may be positioned between the movable member (610) or the coupler (638) described below and the ball screw nut (634). The support member (637) may surround the ball screw bolt (632).

[0173] The coupler (638) can be combined with the movable member (610) and the ball screw bolt (632). The coupler (638) can connect the movable member (610) and the ball screw bolt (632).

[0174] The elastic member (640) can press the movable member (610) toward one or the other side in the radial direction so that the movable member (610) is in close contact with the cam member (710) described later. Specifically, for example, when each movable member (610) of one or more rotary transport units (600) rotates together with the rotary plate (500), the cam member (710) described later can move each movable member (610) toward one or the other side in the radial direction. At this time, the elastic member (640) can press the movable member (610) toward one or the other side in the radial direction so that each movable member (610) is in close contact with the cam member (710) and moves toward one or the other side in the radial direction. That is, the elastic member (640) can pressurize the movable member (610) in one or the other direction opposite to the radial direction in which the cam member (710) presses the movable member (610).

[0175] Accordingly, the movable member (610) can move in close contact with the shape or outline of a predetermined portion (e.g., cam groove) of the cam member (710). Accordingly, the movement error of the movable member (610) in the radial direction to one side or the other is reduced, and accordingly, the rotation error of the rotating member (620) can be reduced, and the rotation angle of the rotating member (620) can be precisely adjusted.

[0176] The elastic member (640) may be disposed between the movable member (610) and the first support member (636). For example, the elastic member (640) may be disposed between the coupler (638) and the first support member (636). For example, the elastic member (640) may be disposed between the coupler (638) and the support member (637).

[0177] Accordingly, a rotary transport device (50) can be implemented with a simple configuration that reduces the movement error of the movable member (610) and the rotation error of the rotary member (620).

[0178] The elastic member (640) can be arranged to surround the ball screw bolt (632) between the moving member (610) or coupler (638) and the first support member (636) or support (637).

[0179]

[0180] [Displacement means]

[0181] The displacement means (700) can move each moving member (610) of one or more rotary transfer units (600) to one or the other radial direction when the moving member (610) of each rotating member (610) rotates together with the rotary plate (500).

[0182] In this way, the rotary transport device (50) may include a rotary plate (500), one or more rotary transport parts (600), and a displacement means (700). Accordingly, the rotary transport device (50) can be easily implemented at low cost with a simple configuration.

[0183] In addition, unlike in the past, since the rotation conversion means (630) and displacement means (700) of one or more rotary transport units (600) can be installed on a rotary plate (500) with a large diameter rather than a rotary shaft with a small diameter, the manufacturing and maintenance of the rotary transport device (50) can be facilitated, and the manufacturing and maintenance costs of the rotary transport device (50) can be reduced. In particular, even if the number of rotary transport units (600) increases, the manufacturing and maintenance of the rotary transport device (50) can be facilitated.

[0184] In addition, since the moving member (610) and the like are installed on the rotary plate (500), the rotary transport device (50) may not be installed on the rotary axis (shaft) that rotates the rotary plate (500). Accordingly, the rotary transport device (50) can be installed and used without interference with other devices that utilize the rotary axis (shaft). In other words, the usability and compatibility of the rotary transport device (50) can be improved.

[0185] In addition, since the moving member (610) of each rotary transport unit (600) moves to one side or the other in the radial direction rather than in the axial direction of the first rotary shaft (A1), the rotary conversion means (630) of each rotary transport unit (600) can be radially arranged in the radial direction (e.g., centrifugal direction) rather than in the axial direction of the first rotary shaft (A1). Accordingly, the distance between the rotary conversion means (630) of the rotary transport units (600) adjacent to each other in the circumferential direction can increase, so that the manufacturing and maintenance of the rotary transport device (50) can be facilitated, and the manufacturing and maintenance costs of the rotary transport device (50) can be reduced. In particular, even if the number of rotary transport units (600) increases, the manufacturing and maintenance of the rotary transport device (50) can be facilitated.

[0186] The displacement means (700) may include a cam member (710). The displacement means (700) may include a housing connecting member (720). The displacement means (700) may include a second support member (730).

[0187] The cam member (710) may be installed on the turntable (500) or adjacent to the turntable (500). The cam member (710) may be installed on the upper portion of the turntable (500). The cam member (710) may be fixed or may rotate at a different speed from the turntable (500).

[0188] The cam member (710) can move each moving member (610) of one or more rotary transfer units (600) to one or the other radial direction when the moving member (610) of each rotating member (610) rotates together with the rotary plate (500).

[0189] Accordingly, the displacement means (700) can be easily implemented at low cost with a simple configuration.

[0190] The cam member (710) may be disc-shaped or ring-shaped. The cam member (710) may include a cam groove (712).

[0191] A movable member (610) may be inserted into a cam home (712). The cam home (712) may have a different distance from the first rotational axis (A1) depending on its angular position relative to the first rotational axis (A1). Accordingly, when each movable member (610) of one or more rotary transfer units (600) rotates together with the rotary plate (500), each movable member (610) may be moved to one or the other radial direction.

[0192] Accordingly, the displacement means (700) can be easily implemented at low cost with a simple configuration.

[0193] The cam home (712) may have a circular shape eccentric from the first rotation axis (A1).

[0194] Accordingly, the rotation cycle of the rotating plate (500) for the cam member (710) and the rotation cycle of the rotating member (620) can correspond.

[0195] In a case where the first rotation axis (A1) extends in the vertical direction and one or more rotation transfer parts (600) and cam members (710) are installed on the upper part of the rotation plate (500), the cam groove (712) can be formed on the upper surface of the cam member (710).

[0196] Accordingly, the stability and durability of the rotary transport device (50) can be improved.

[0197] The housing connecting member (720) can connect the cam member (710) to the housing. Accordingly, the cam member (710) can be fixed to the housing.

[0198] The second support member (730) can be installed on the rotary plate (500). The second support member (730) can rotate together with the rotary plate (500). The second support member (730) can have an overall ring shape.

[0199] The second support member (730) may include one or more holes. The second support member (730) may include a support portion (732) and a cover portion (734). The second support member (730) may include one or more guide surfaces (736).

[0200] One or more rotary transfer units (600) can be inserted and positioned in each of one or more holes.

[0201] The support member (732) may be positioned radially outside the cam member (710).

[0202] The cover part (734) may be formed to extend radially inward from the support part (732). As described above, when the first rotation axis (A1) extends in the vertical direction, one or more rotation transfer parts (600) and cam members (710) are installed on the upper part of the rotary plate (500), and a cam groove (712) is formed on the upper surface of the cam member (710), the cover part (734) may be positioned on the upper part of the cam groove (712). The cover part (734) may be configured to include one or more guide surfaces (736) described below.

[0203] Accordingly, a displacement means (700) including a second support member (730) can be easily implemented at low cost with a simple configuration. In addition, the stability and durability of the rotary transport device (50) can be improved.

[0204] One or more guide surfaces (736) may be one or the other inner surface of the circumferential direction of one or more of the aforementioned holes formed in the second support member (730).

[0205] Accordingly, one or more guide surfaces (736) can be easily implemented at low cost with a simple configuration.

[0206] One or more guide surfaces (736) can rotate together with the turntable (500).

[0207] Each guide surface (736) can be formed to extend radially to one side or the other. Each guide surface (736) can guide the movement of each moving member (610) of one or more rotary transfer units (600) to one side or the other in the radial direction.

[0208] Accordingly, the stability and durability of the rotary transport device (50) can be improved.

[0209] Each guide surface (736) may be capable of pressing the moving member (610) of each of one or more rotary transfer units (600) in a circumferential direction surrounding the first rotation axis (A1).

[0210] Accordingly, the stability and durability of the rotary transport device (50) can be improved.
