Technical Field
[0001] This utility model relates to the field of devices and equipment for automated garment manufacturing systems, specifically a shaft coupling structure and conveyor drive assembly for an automated garment hanging system. Background Technology
[0002] Automated intelligent garment manufacturing conveyor line technology is a production line that integrates high-tech equipment such as automated devices, robots, and sensors. It utilizes computer technology to coordinate materials, information, and machines, featuring high automation, high flexibility, and information-based operation. This significantly improves production efficiency, reduces costs, and achieves transparency and optimization of the production process. Currently, manufacturers have developed and designed various types of garment hanging systems tailored to different application scenarios.
[0003] For example, the garment hanger transfer device disclosed in Chinese invention patent application No. 201810221866.3 is used to transfer the garment hanger between opposite sides of a ring rail. An opening is provided on one side of the ring rail, and a partition is provided on the other side. A track-changing rod is hinged to one side of the opening. The outer end of the track-changing rod is used to switch vertically between the other side of the opening and the inlet end of the primary descending rail located below the ring rail. A secondary lifting device is used to lift the garment hanger to be transferred vertically to the partition. A connecting rod in the secondary lifting device is used to insert into the partition to create a passage for the ring rail at the partition. A track-changing mechanism is provided between the secondary lifting device and the outlet end of the primary descending rail. For example, Chinese invention patent application CN201811638089.9 discloses a garment hanging system hanger fast delivery device for conveying hangers between opposite sides of a ring track. The ring track has an opening on one side and a partition on the other. A curved track is located below the ring track. The drive mechanism is adapted to the direction of the curved track and has several drive components for driving the hangers on the curved track from the inlet end to the outlet end. A lowering mechanism is located between the inlet end of the curved track and the opening to move the hangers on the ring track to the inlet end of the curved track. A lifting mechanism is located between the outlet end of the curved track and the partition to lift the hangers on the curved track from the outlet end of the curved track onto the ring track.
[0004] In these automated garment conveyor systems, the most important technical objective is to use conveyor belts to transport semi-finished or finished garments to target areas for further processing or storage, according to various needs. Therefore, these systems require motors as drive units and conveyor chain mechanisms. In the garment conveyor field, space needs to be reserved below each conveyor line for hangers and garment movement; therefore, guide rails, conveyor chains, and motors as drive units all need to be installed at a certain height above the ground. Considering the overall load-bearing capacity, many components in the conveyor line are made of plastic resin to achieve a lightweight overall structure. However, the applicant found that in common drive structures, the motor output shaft and the plastic material are usually connected by a key. In this structure, uneven transmission forces can easily damage the plastic drive wheels, affecting the stable and continuous operation of the conveyor system.
[0005] To address the aforementioned issues, this utility model provides a shaft coupling structure for an automated garment hanging system and a conveyor drive assembly incorporating the structure. The shaft coupling structure effectively improves the uniformity of the force transmitted from the drive motor to the drive wheel, preventing damage to the plastic drive wheel under heavy loads, thereby enhancing the overall operational stability and reliability of the system. Utility Model Content
[0006] This utility model provides a shaft coupling structure for an automated garment hanging system and a conveyor drive assembly including the structure. The shaft coupling structure can effectively improve the uniformity of the force transmitted from the drive motor to the drive wheel, avoid damage to the plastic drive wheel under heavy load, and thus improve the overall operational stability and reliability of the system.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0008] A shaft coupling structure for an automated garment hanging system is characterized by comprising a drive tooth profile formed on a connecting bushing and a mating tooth profile formed on a drive wheel. The drive tooth profile and the mating tooth profile are correspondingly conical, and the drive tooth profile and the mating tooth profile abut and engage with each other, so that the drive wheel can be driven to rotate when the connecting bushing rotates.
[0009] As a preferred embodiment of the present invention, the front end of the connecting bushing extends forward and protrudes to form an insertion portion, and the driving tooth surface is formed on the outer side of the insertion portion; the rear end of the central connecting section on the drive wheel has a recessed slot portion, and the mating tooth surface is formed on the inner side of the slot portion; the insertion portion can be inserted into the slot portion and the driving tooth surface and the mating tooth surface are in a mutually abutting and engaging state.
[0010] As a preferred embodiment of the present invention, the plug-in portion includes a front first plug-in segment and a rear second plug-in segment. The radial dimension of the first plug-in segment is smaller than that of the second plug-in segment, and independent driving tooth profiles are formed at the front ends of the first and second plug-in segments, respectively. The slot portion has a first slot segment and a second slot segment corresponding to the plug-in portion, and independent mating tooth profiles are also formed at the rear ends of the first plug-in segment and the second slot segment, respectively, which correspond to and engage with the aforementioned driving tooth profiles located at different positions.
[0011] As a preferred embodiment of the present invention, the combination formed by the front drive tooth profile and the mating tooth profile, and the combination formed by the rear drive tooth profile and the mating tooth profile, are respectively located on the front and rear sides of the upper toothed disc of the drive wheel.
[0012] As a preferred embodiment of this utility model, it also includes a fastening nut disposed inside the connecting bushing and a fastening bolt installed at the front end of the central connecting section. The fastening bolt can pass through the central connecting section and the connecting bushing from front to back and then lock and fix with the fastening nut, thereby achieving a tight abutment and fit between the driving tooth surface and the mating tooth surface.
[0013] As a preferred embodiment of the present invention, it further includes a locking connector for fixing the connecting bushing to the output shaft of the drive motor; a sleeve cavity extending forward for the drive motor's output shaft to be inserted is provided at the rear end of the connecting bushing, a locking through hole is provided on the connecting bushing, and a locking through groove is provided on the output shaft, the locking connector being able to pass through both the locking through hole and the locking through groove simultaneously to achieve the connection and fixation of the connecting bushing and the output shaft.
[0014] A conveying drive assembly includes a drive motor, a drive wheel, and a connecting bushing disposed between the drive motor and the drive wheel, wherein the drive motor, the drive wheel, and the connecting bushing form the aforementioned shaft connection structure for an automated garment hanging system.
[0015] As a preferred embodiment of the present invention, the drive wheel includes a connecting center section that serves as a connection and a toothed disc portion surrounding the outside of the connecting center section, the toothed disc portion also being provided with reinforcing ribs.
[0016] In summary, this utility model can achieve the following beneficial effects:
[0017] The automated garment hanging system presented in this utility model utilizes a shaft-connected structure, transforming the traditional key-based connection between the drive wheel and the motor output shaft or bushing in a conveyor system into a transmission mode where the toothed surfaces at the ends of the two components mesh with each other. This structural optimization allows the torsional force borne by the drive wheel to be transmitted more evenly to the outer peripheral gear disc and teeth. Especially for drive wheels made of plastic or resin materials, this significantly reduces localized breakage damage caused by uneven stress, making it possible to achieve overall lightweighting of the conveyor system. Furthermore, based on this structure, this embodiment creatively employs two independent toothed surfaces located on different sections of the bushing component, simultaneously providing driving force to the drive wheel. Since the two toothed surfaces are located on the front and rear sides of the drive wheel's gear disc, the bushing can provide driving force to the gear disc from both sides simultaneously. Therefore, unlike transmission methods with large-area meshing on one side, this effectively avoids the problem of deformation or even breakage of the drive wheel's gear disc relative to the meshing area under sudden large load impacts, further improving the overall stability and reliability of the system.

[0031] The following specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
[0032] This solution is achieved through the following technical means:
[0033] Example: In the example, a specific implementation method of the shaft coupling structure for an automated garment hanging system is given, as well as a conveyor drive component including the shaft coupling structure.
[0034] First, to more clearly demonstrate the working scenario of this structure and its achievable technical effects, this embodiment requires the introduction of a conveyor drive assembly incorporating this shaft coupling structure. Specifically, refer to the appendix to the specification. Figure 1 Taking the illustrated state as an example, the conveying drive assembly given in this embodiment includes a drive motor 6, a drive wheel 2, and a connecting bushing 1 disposed between the drive motor 6 and the drive wheel 2. The drive wheel 2 is made of lightweight materials such as plastic or resin, and includes a cylindrical connecting center section 201 located at the center and serving a connecting function, and a geared disc portion 202 surrounding the outside of the connecting center section 201. Reinforcing ribs 203 are also provided on the geared disc portion 202. (Refer to the appendix of the specification.) Figure 3 The outer periphery of the toothed disc 202 here has several concave and convex teeth. In this structure, the drive motor 6 drives the drive wheel 2, which is fixed to its output shaft 601, to rotate. Since the transmission chain used to transmit power in the guide rail mechanism of the conveying system covers and surrounds the outside of the drive wheel 2, and the drive chain meshes with the teeth, the conveyor chain will move forward continuously under the drive of the drive motor 6, thereby realizing the continuous movement of the conveyor frame and the product material to be moved, which are attached to the drive chain, towards the target location area.
[0035] The most important technical invention in this utility model application is the optimization and improvement of the connection structure between the output shaft 601 of the drive motor 6 and the drive wheel 2 in the traditional conveying drive assembly. This shaft connection structure can achieve uniform force distribution under high load even for the lightweight and relatively fragile drive wheel 2, thereby ensuring the overall stable and reliable continuous movement of the conveying system.
[0036] The optimized automated garment hanging system provided in this solution uses a shaft coupling structure comprising a drive tooth profile 101 formed on a connecting bushing 1 and a mating tooth profile 21 formed on a drive wheel 2. The drive tooth profile 101 and the mating tooth profile 21 are correspondingly conical, and they abut and engage with each other, enabling the connecting bushing 1 to drive the drive wheel 2 to rotate when it rotates. Specifically, refer to the appendix to the specification. Figure 5 and 6 Taking the structure shown as an example, the front end of the connecting bushing 1 extends forward to form a protruding insertion part 102, and the driving tooth surface 101 is formed on the outer side of the insertion part 102; the rear end of the central connecting section on the drive wheel 2 is provided with a recessed slot part 22, and the mating tooth surface 21 is formed on the inner side of the slot part 22; the insertion part 102 can be inserted into the slot part 22 and realize the driving tooth surface 101 and the mating tooth surface 21 abutting and engaging with each other.
[0037] In existing shaft-connected transmission structures, where only a single flat key connects the drive motor 6, when the output shaft 601 rotates to provide torque, this powerful torque is entirely applied to a very small force-bearing surface of the drive wheel 2 through one side of the flat key's contact surface. Since the transmission chain covers multiple teeth on the outer side of the drive wheel 2, the distribution of internal and external forces on the plastic or composite resin material is extremely uneven, easily leading to deformation or even breakage of the drive wheel 2 made of lightweight materials such as plastic.
[0038] In this application, a driving tooth surface 101 and a mating tooth surface 21 are formed on the connecting bushing 1 and the drive wheel 2, respectively. Both tooth surfaces have a plurality of meshing teeth evenly spaced in a ring. Therefore, when the driving tooth surface 101 and the mating tooth surface 21 abut against each other, the corresponding meshing teeth on the two components will mesh with each other. At this time, when the connecting bushing 1, which is fixedly mounted on the output shaft 601, rotates with the operation of the drive motor 6, it will transmit power evenly to the drive wheel 2 through these meshing teeth, thereby greatly avoiding the problem of local deformation and damage caused by uneven force.
[0039] Furthermore, the applicant discovered that if engagement is achieved solely through unilateral contact, a certain transmission distance exists between the meshing surface and the gear disc 202. This can easily lead to deformation or even breakage of the portion between the meshing surface and the gear disc 202 under conditions of excessive instantaneous torsional torque. Therefore, the inventors further optimized and improved the aforementioned structure. (See attached specification) Figure 4 and 5 Taking the partially enlarged structural diagram as an example, this embodiment adjusts the structure of the aforementioned insertion portion 102, dividing it into a first insertion segment 1021 at the front and a second insertion segment 1022 at the rear. The radial dimension of the first insertion segment 1021 is smaller than that of the second insertion segment 1022, and independent driving tooth surfaces 101 are formed at the front ends of both segments. Correspondingly, a first slot segment 221 and a second slot segment 222, corresponding to the insertion portion 102, are also formed within the slot portion 22 on the drive wheel 2. Independent mating tooth surfaces 21 are also formed at the rear ends of the first insertion segment 1021 and the second slot segment 222, respectively, engaging with the aforementioned driving tooth surfaces 101 located at different positions, with each tooth portion abutting and meshing with the others. The combination formed by the front drive tooth profile 101 and the mating tooth profile 21, and the combination formed by the rear drive tooth profile 101 and the mating tooth profile 21, are located on the front and rear sides of the toothed disc portion 202 of the drive wheel 2, respectively. With this structure, since the two tooth profiles are located on the front and rear sides of the toothed disc portion 202 of the drive wheel 2, the connecting bushing 1 can simultaneously provide driving force to the toothed disc from both sides. Therefore, unlike transmission methods with large-area meshing on one side, this effectively avoids the problem of deformation or even breakage of the toothed disc portion 202 of the drive wheel 2 relative to the meshing area when subjected to a large instantaneous load impact, further improving the overall stability and reliability of the system.
[0040] It should be further noted that the connecting bushing 1 can be made of aluminum alloy. Since it is hollow inside and fitted onto the end of the output shaft 601 of the drive motor 6, it has little impact on the overall weight of the conveyor line. Of course, to achieve a tight fit between the two toothed surfaces in the aforementioned shaft connection structure, a clamping force along the axial direction is required between the drive wheel 2 and the connecting bushing 1. In this solution, a connection structure using a fastening nut 3 and a fastening bolt 4 is employed. For details, please refer to the appendix of the instruction manual. Figure 2 and 6The structure shown first involves fixing a fastening nut 3 to the end of the inner cavity of the connecting bushing 1. The fastening bolt 4 passes sequentially from front to back through the central connecting section and the connecting bushing 1, then locks itself to the fastening nut 3. This clamping force ensures a tight fit between the driving tooth surface 101 and the mating tooth surface 21, guaranteeing a stable transmission effect. For the part of the structure that fixes the connecting bushing 1 to the output shaft 601 of the drive motor 6, please refer to the appendix to the instruction manual. Figure 2 and 6 As shown in the structure, a sleeve cavity 103 extending forward is first opened at the rear end of the connecting bushing 1 for the insertion of the output shaft 601 of the drive motor 6. A locking through hole 104 is opened on the connecting bushing 1, and a locking through groove 602 is opened on the output shaft 601. Both the locking through hole 104 and the locking through groove 602 have internal threads. At this time, it is only necessary to screw the screw component with external threads between the two components as a locking connector 5 to achieve a reliable connection and fixation, ensuring the stable and efficient transmission process from the drive motor 6 to the drive wheel 2.
[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
