The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0028] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or features, these components or features should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one feature from another. Furthermore, the term "or" as used in this document should, as appropriate, include any combination of one or more related listed items.

[0029] Please see Figures 1 to 11 As shown, this is one embodiment of the present invention. Figure 1 As shown, this embodiment discloses a conveying system 1000, which can be applied to an Overhead Shuttle (OHS) or Overhead Hoist Transfer (OHT) system as needed, but this utility model is not limited thereto. Further, in this embodiment, the conveying system 1000 includes a track 200 and a conveying device 100 mounted on the track 200. The track 200 includes a straight section 201 and a turning section 202 connected to the straight section 201, and the conveying device 100 is used to move along the track 200.

[0030] The conveying device 100 is, for example, a transport vehicle, and includes a vehicle body 1 for carrying goods and a plurality of steering modules 2 located on opposite sides of the vehicle body 1. Furthermore, the vehicle body 1 can abut against the inner side of the track 200 and move along the track 200 via its plurality of main wheels 11 and plurality of auxiliary wheels 12, while the plurality of steering modules 2 guide the vehicle body 1 when it turns.

[0031] It should be further noted that although the steering module 2 is described in this embodiment as being used in conjunction with the vehicle body 1, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the steering module 2 may also be used independently (e.g., for sale) or in conjunction with other components, depending on the requirements.

[0032] Furthermore, since the multiple steering modules 2 in this embodiment adopt a substantially similar structure, for ease of understanding, the following description will first describe the structure of one of the steering modules 2, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the structures of the multiple steering modules 2 may also differ slightly.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, the steering module 2 includes a wheel rim 21, a reduction mechanism 22 mounted on the wheel rim 21, and a guide wheel mechanism 23 mounted on the wheel rim 21 and connected to the reduction mechanism 22. The wheel rim 21 is fixed to the vehicle body 1, and the wheel rim 21 is configured corresponding to one of the main wheels 11 (e.g., the wheel rim 21 is mounted on the outside of one of the main wheels 11), but this invention is not limited thereto.

[0034] Furthermore, such as Figures 3 to 5 As shown, the reduction mechanism 22 is generally located between the wheel rim 21 and the corresponding main wheel 11. In this embodiment, the reduction mechanism 22 includes a reducer 221, a rotating shaft 222 mounted on the reducer 221, and a shim 223 disposed between the reducer 221 and the rotating shaft 222. However, this invention is not limited to this. For example, in other embodiments not shown in this invention, the installation and fixation between the reducer 221 and the rotating shaft 222 can be achieved by means or components other than the shim 223.

[0035] In this embodiment, the reducer 221 has an output shaft 2211, and the output shaft 2211 may be located on the center line C11 corresponding to the main wheel 11. The rotating shaft 222 is sleeved on the output shaft 2211 and can rotate synchronously. The shim 223 is located inside the rotating shaft 222 and locked to the output shaft 2211, so that the rotating shaft 222 is installed on the output shaft 2211.

[0036] Furthermore, the rotating shaft 222 is recessed with a groove 2221 along a predetermined direction D (perpendicular to the center line C11). In this embodiment, the groove 2221 may penetrate the rotating shaft 222 along the predetermined direction D, so that the rotating shaft 222 includes two support arms 2223 located on opposite sides of the groove 2221, and the inner surfaces of the two support arms 2223 are each recessed with an arc groove 2222 communicating with the groove 2221, and the gasket 223 is disposed within the groove 2221 and the two arc grooves 2222 and presses against the output shaft 2211.

[0037] It should be further noted that although the reduction mechanism 22 is described in this embodiment as described above, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the installation and fixing between the reducer 221 and the rotating shaft 222 can be achieved by means or components other than the gasket 223; or, the rotating shaft 222 can adopt a configuration other than a cylinder (e.g., a polygonal prism).

[0038] Furthermore, in this embodiment, the rotating shaft 222 is described in conjunction with the guide wheel mechanism 23, and they can be collectively referred to as a guide module M. The guide wheel mechanism 23 can be positioned relative to the wheel rim 21 in an initial position (e.g., via the reduction mechanism 22). Figure 2 ) and a guide position (e.g.: Figure 3 Rotate between )

[0039] In this embodiment, the guide wheel mechanism 23 is generally elongated, and when the guide wheel mechanism 23 is in the initial position (e.g.: Figure 2 The guide wheel mechanism 23 does not touch the track 200 and its length direction is generally parallel to the track 200; when the guide wheel mechanism 23 is in the guiding position (e.g.: Figure 3 The guide wheel mechanism 23 abuts against the track 200 and its length direction is generally perpendicular to the track 200, but this utility model is not limited thereto.

[0040] It should be noted that, in other embodiments not shown in this utility model, the guide module M may also be used independently (e.g., for sale) or in combination with other components as needed. Furthermore, for ease of understanding this embodiment, the following description will assume that the guide wheel mechanism 23 is located in the guide position.

[0041] The guide wheel mechanism 23 includes a swing arm 231 fixed to the wheel frame 21, a rotating seat 232 connected to the swing arm 231, and a guide wheel 233 pivotally connected to the swing arm 231. In this embodiment... Figure 5In this design, the swing arm 231, the rotating seat 232, and the guide wheel 233 are independent components, but this invention is not limited thereto. For example, such as Figure 11 As shown, the swing arm 231 and the rotating seat 232 can be a single-piece structure that is integrally connected.

[0042] Furthermore, such as Figure 4 and Figure 6 As shown, the swing arm 231 includes a receiving section 231a fixed to the wheel frame 21 and a pivot section 231b connected to the bottom edge of the receiving section 231a. The swing arm 231 has an assembly slot 2311 in the receiving section 231a corresponding to the rotating shaft 222. The rotating seat 232 is mounted in the assembly slot 2311 and is connected to the rotating shaft 222.

[0043] It should be noted that the assembly and disassembly structure between the swing arm 231 and the rotating seat 232 can be implemented in various ways according to different needs. For the sake of understanding this embodiment, the following description will be based on one of the embodiments of the swing arm 231 and the rotating seat 232, but this utility model is not limited thereto.

[0044] like Figure 5 , Figure 7 ,and Figure 8 As shown, in this embodiment, the assembly slot 2311 has a receiving slot 2312, a through hole 2313, and two side through holes 2314 respectively connected to opposite sides of the through hole 2313. The receiving slot 2312 is formed by a recess on the surface of the receiving section 231a away from the wheel frame 21, and the through hole 2313 and the two side through holes 2314 are located inside the receiving slot 2312. The walls of the two side through holes 2314 are generally circular, and their centers are located within the through hole 2313.

[0045] Furthermore, the rotating seat 232 has a base 2321 and a protruding rib 2322 extending from the base 2321. The base 2321 is generally plate-shaped and its shape corresponds to the receiving groove 2312, and the base 2321 is disposed in the receiving groove 2312. The protruding rib 2322 is elongated and protrudes from the assembly slot 2311 (e.g., through the through hole 2313) and is embedded in the groove 2221 of the rotating shaft 222. The two support arms 2223 of the rotating shaft 222 are respectively inserted into the two side through holes 2314. That is, in this embodiment, the end of any one of the support arms 2223 is located between the protruding rib 2322 and the hole wall corresponding to the side through hole 2314.

[0046] Furthermore, the rib 2322 is spaced apart from the bottom of the groove 2221 (along the center line C11) by a gap, and in this embodiment, the rib 2322 is generally held between the two supports 2223 and protrudes from both ends of the groove 2221 along the preset direction D. That is, as... Figure 9 and Figure 10 As shown, the guide wheel mechanism 23 can be driven to rotate by the reduction mechanism 22 through the cooperation of the convex rib 2322 and the rotating shaft 222, and the guide wheel mechanism 23, through the interval, allows the convex rib 2322 to swing only within the groove 2221, thereby forming a floating cooperation mechanism with a single degree of freedom between the convex rib 2322 and the rotating shaft 222.

[0047] The guide wheel 233 is pivotally connected to the pivot segment 231b of the swing arm 231. The guide wheel 233 can rotate about a pivot axis C233, and the pivot axis C233 is parallel to the preset direction D. That is, the steering module 2 (or the guidance module M) enables the guide wheel 233 to be subjected to force through the floating engagement mechanism, so as to drive the guide wheel mechanism 23 to swing relative to the rotating shaft 222 (e.g., the guide wheel mechanism 23 can only swing along a plane defined by the pivot axis C233 and the center line C11).

[0048] Therefore, in this embodiment, the steering module 2 (or the guide module M) uses a floating engagement mechanism between the rib 2322 and the rotating shaft 222 to facilitate quick assembly and disassembly, and allows the guide wheel mechanism 23 to swing to counteract the force required by the deceleration mechanism 22 (e.g., the output shaft 2211), thereby avoiding damage to the components of the deceleration mechanism 22.

[0049] More specifically, in this embodiment, the guide wheel 233 can be subjected to force to drive the guide wheel mechanism 23 to swing relative to the pivot axis 222 by a buffer angle σ, which is defined as the angle between the pivot axis C233 and a plumb line (or the preset direction D) and is not greater than 5 degrees. Therefore, in this embodiment, the steering module 2 (or the guidance module M) limits the value of the buffer angle σ (e.g., not greater than 5 degrees) so that the guide wheel mechanism 23 can not only effectively counteract the force but also simultaneously prevent the guide wheel mechanism 23 from undergoing irreversible deformation.

[0050] Based on the above, as Figures 2 to 4As shown, when the conveying device 100 moves from the straight section 201 of the track 200 to the turning section 202, the guide wheel mechanism 23 of each turning module 2 rotates relative to the wheel frame 21 from the initial position to the guiding position through the deceleration mechanism 22. The guide wheel 233 rolls along the side edge of the turning section 202 and can be forceped to drive the guide wheel mechanism 23 to swing relative to the rotating shaft 222.

[0051] [Technical Effects of the Embodiments of this Utility Model]

[0052] In summary, the conveying system and the steering module and guide module of the conveying equipment disclosed in this utility model embodiment facilitate quick assembly and disassembly through a floating engagement mechanism formed between the ribs and the rotating shaft, and enable the guide wheel mechanism to offset the force required by the deceleration mechanism by swinging, thereby avoiding damage to the components of the deceleration mechanism.
