Description

Technical Field

[0001] This utility model relates to the field of garment production technology, and in particular to a drive device and its garment hanging production line. Background Technology

[0002] Garment hanging lines are used to transport garments and typically include a drive unit, a main rail sprocket, a chain, and a push rod. The drive unit drives the main rail sprocket to rotate, which in turn drives the chain to move and the push rod to move. The push rod then pushes the hanger wheels to rotate on the production line.

[0003] However, when the main track chain jams abnormally or the pushed hanger gets stuck abnormally, the chain will stop rotating. The continuous rotation of the drive component will continue to exert force on the main track sprocket, causing excessive force to directly disengage the chain from the main track sprocket, making the main track line unusable. The entire production line needs to be dismantled and repaired, which will have a significant impact on production. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a driving device.

[0005] A driving device, applied to a garment hanging production line, includes: a driving assembly comprising a driving member and a driving shaft, the driving member being fixed to the main rail profile of the garment hanging production line, and the driving shaft being connected to the driving member; a transmission assembly sleeved on the outer periphery of the driving shaft and fixedly connected to the driving shaft; and a sprocket assembly at least partially abutting against the transmission assembly, the sprocket assembly being capable of rotating relative to the transmission assembly in response to a first external force; wherein the first external force is set to F1, and the maximum output force of the driving member is F2, satisfying F1 < F2.

[0006] In this configuration, the drive assembly powers the sprocket assembly, which in turn drives the chain in the garment hanging production line. The drive component connects to the drive shaft, causing it to rotate. The drive shaft then powers a transmission assembly fixedly connected to it. This transmission assembly connects to the sprocket assembly, and through friction, drives the sprocket assembly to rotate. If certain parts of the garment hanging production line jam, preventing the chain from continuing to run, the sprocket will also stop rotating. If the drive component continues to drive the sprocket, it can easily lead to drive component failure and chain detachment or deformation, causing serious production disruptions. To address this, the sprocket assembly can rotate relative to the transmission assembly in response to a first external force, which is less than the maximum output force of the drive component. Therefore, when the sprocket assembly jams while the drive shaft continues to rotate, the transmission assembly can engage with the sprocket assembly through relative sliding. Friction between them keeps the sprocket assembly stationary, while the drive and transmission assemblies continue to rotate. It prevents further force from being applied to the main rail sprocket, thus preventing the chain from being forcibly disengaged. It also provides anti-derailment protection for the main rail sprocket and chain. Once the chain is no longer stuck and the torque returns to normal, the drive unit resumes normal friction transmission to continue driving the main rail sprocket to rotate normally. There is no need to disassemble or adjust the drive assembly; only the chain jamming issue needs to be resolved, making subsequent maintenance and repairs very convenient.

[0007] In one embodiment, the transmission assembly includes a bushing with a flange protruding from its outer periphery, and the sprocket assembly abuts against the flange.

[0008] In one embodiment, the sprocket assembly includes a main rail sprocket, a first friction plate, and a pressure plate. The main rail sprocket is rotatably connected to the outer periphery of the bushing. The first friction plate is located between the pressure plate and the main rail sprocket. The pressure plate presses against one side of the first friction plate along the axial direction of the drive shaft, and causes the main rail sprocket to abut against the flange.

[0009] In one embodiment, the sprocket assembly further includes a second friction plate, which is disposed on both sides of the main rail sprocket, along the axial direction of the drive shaft, with the second friction plate located between the main rail sprocket and the flange.

[0010] In one embodiment, the sprocket assembly further includes an adjusting member, which is sleeved on the outer periphery of the bushing and located on the side of the main rail sprocket away from the drive member, and the adjusting member is threadedly engaged with the bushing.

[0011] In one embodiment, an elastic pad is provided between the adjusting member and the first friction plate, and the axial sides of the elastic pad abut against the adjusting member and the first friction plate, respectively.

[0012] In one embodiment, the sprocket assembly further includes a bushing that is fitted onto the outer periphery of the bushing and is movably connected to the bushing, and the main rail sprocket is connected to the outer periphery of the bushing.

[0013] In one embodiment, the drive member and the drive shaft are keyed together, and the drive shaft and the bushing are keyed together.

[0014] In one embodiment, the drive device further includes a first bearing assembly and a second bearing assembly. The first bearing assembly includes a first bearing seat and a first fixing plate. The first bearing seat is connected to the first fixing plate, and the first fixing plate is connected to the main rail profile. The second bearing assembly includes a second bearing seat and a second fixing plate. The second bearing seat and the second fixing plate are connected, and the second fixing plate is connected to the main rail profile. The drive shaft passes through the first bearing seat and the second bearing seat and is rotatably connected to the first bearing seat and the second bearing seat, respectively.

[0015] This utility model also provides a garment hanging production line, including the drive device as described above, as well as a main rail profile and a chain, the chain being wound around the sprocket assembly.

[0016] Compared to existing technologies, this invention uses a pressure plate and a first friction plate to slidably connect the sprocket assembly and the transmission assembly. During normal operation of the garment hanging production line, the friction between the transmission assembly and the sprocket assembly is sufficient to drive the sprocket assembly to rotate, thus driving the chain. When the chain or other structures accidentally jam, preventing the sprocket assembly from rotating, the driving force of the drive component is greater than the friction between the sprocket assembly and the transmission assembly. Therefore, the drive component can drive the transmission assembly to rotate normally relative to the sprocket assembly. Relative friction is generated between the transmission assembly and the sprocket assembly, changing to a clutch state, thereby preventing the chain from forcibly disengaging from the sprocket and also providing anti-derailment protection for the main rail sprocket and chain.

[0028] Please see Figures 1-4 This utility model provides a drive device 100, which is applied to a garment hanging production line. It can generate relative displacement between the sprocket and the transmission component 20 after the chain 60 and sprocket in the garment hanging production line are accidentally jammed. This prevents the drive component 11 from continuously outputting and causing the sprocket to continue to rotate, which could cause the chain 60 to fall off or even deform, seriously affecting the production line.

[0029] A drive device 100 includes a drive assembly 10, a transmission assembly 20, and a sprocket assembly 30. The drive assembly 10 includes a drive member 11 and a drive shaft 12. The drive member 11 is fixed to the main rail profile of the garment hanging production line, and the drive shaft 12 is connected to the drive member 11. The transmission assembly 20 is sleeved on the outer periphery of the drive shaft 12 and is fixedly connected to the drive shaft 12. The sprocket assembly 30 at least partially abuts against the transmission assembly 20 and is capable of rotating relative to the transmission assembly 20 in response to a first external force. The first external force is set to F1, and the maximum output force of the drive member 11 is F2, satisfying F1 < F2. Thus, the drive assembly 10 drives the sprocket assembly 30 to rotate, which in turn drives the chain 60 in the garment hanging production line. The drive component 11 is connected to the drive shaft 12, which drives the drive shaft 12 to rotate. The drive shaft 12 then drives the transmission component 20, which is fixedly connected to it, to rotate. The transmission component 20 is connected to the sprocket assembly 30, and through the friction with the sprocket assembly 30, it drives the sprocket assembly 30 to rotate.

[0030] When certain parts of the garment hanging production line jam, causing the chain 60 to stop operating, the sprocket will also stop rotating. If the drive component 11 continues to drive the sprocket, it is easy for the drive component 11 to malfunction, and the chain 60 may also fall off or deform, causing serious production problems. To address this, the sprocket assembly 30 can rotate relative to the transmission component 20 in response to a first external force. Since the first external force is less than the maximum output force of the drive component 11, when the sprocket assembly 30 jams while the drive shaft 12 continues to rotate, the transmission component 20 can engage with the sprocket assembly 30 through relative sliding. Friction exists between them, and the sprocket assembly 30 remains stationary while the drive component 10 and transmission component 20 continue to rotate. This prevents further force from being applied to the main rail sprocket 31 to forcibly disengage the chain 60, and also provides anti-derailment protection for the main rail sprocket 31 and the chain 60. When the torque on the chain 60 returns to normal after the jamming is resolved, the drive component 11 resumes normal friction transmission to continue driving the main rail sprocket 31 to rotate normally. There is no need to disassemble and adjust the drive component 10; it is only necessary to resolve the jamming of the chain 60. This makes subsequent maintenance and repair very convenient.

[0031] It should be explained that in this embodiment, the first external force F1 is actually generated by frictional torque. Assuming the frictional torque between the transmission assembly 20 and the sprocket assembly 30 is set to M1, the rated torque driven by the drive component 11 during normal operation is set to M2, and the maximum limiting torque is set to M3, requiring M3 > M1 > M2. When the chain 60 jams, the drive component 11 will continuously apply force to the main rail sprocket 31, causing the torque to gradually increase from M2 to M3. When the torque reaches M3, exceeding the maximum torque M1 generated between the transmission assembly 20 and the sprocket assembly 30, relative slippage occurs between the transmission assembly 20 and the sprocket assembly 30, achieving disengagement. In this embodiment, the drive component 11 uses an asynchronous motor.

[0032] Furthermore, the transmission assembly 20 includes a bushing 21, with a flange 211 protruding from the outer periphery of the bushing 21, and the sprocket assembly 30 abuts against the flange 211. Thus, the friction between the sprocket assembly 30 and the transmission assembly 20 is generated by the frictional force produced by the abutment between the sprocket assembly 30 and the flange 211, and the tighter the abutment between the sprocket assembly 30 and the flange 211, the greater the frictional force.

[0033] Of course, it is understandable that friction control between the transmission assembly 20 and the sprocket assembly 30 can be achieved in other ways in other embodiments. For example, a connector can be provided between the sprocket assembly 30 and the transmission assembly 20. The connector is connected to the inner wall of the sprocket assembly 30 and also to the outer wall of the transmission assembly 20. The connector is tightly connected to both the sprocket assembly 30 and the transmission assembly 20, so that the transmission assembly 20 drives the sprocket assembly 30 through the connector. A set abutment force is provided to control that when the force reaches F1, at least two of the transmission assembly 20, the connector, and the sprocket assembly 30 will slip.

[0034] Furthermore, the sprocket assembly 30 includes a main rail sprocket 31, a first friction plate 32, and a pressure plate 38. The main rail sprocket 31 is rotatably connected to the outer periphery of the bushing 21. The first friction plate 32 is located between the pressure plate 38 and the main rail sprocket 31. The pressure plate 38 presses against one side of the first friction plate 32 along the axial direction of the drive shaft 12, and causes the main rail sprocket 31 to abut against the flange 211. In this way, the main rail sprocket 31 is pressed against the flange 211 of the bushing 21 by the abutting force of the pressure plate 38, and the first friction plate 32 is also pressed against the main rail sprocket 31. There is a frictional torque between the two, thereby setting the friction force.

[0035] The sprocket assembly 30 also includes a second friction plate 33. The second friction plate 33 and the first friction plate 32 are respectively disposed on both sides of the main rail sprocket 31. Along the axial direction of the drive shaft 12, the second friction plate 33 is located between the main rail sprocket 31 and the flange 211. In this way, the second friction plate 33 can make the flange 211 bear force evenly, avoiding friction damage. The second friction plate 33 is easier to replace than the bushing 21, thus facilitating the later maintenance of the device.

[0036] Furthermore, the sprocket assembly 30 also includes an adjusting member 34, which is sleeved on the outer periphery of the bushing 21 and located on the side of the main rail sprocket 31 away from the drive member 11. The adjusting member 34 is threadedly engaged with the bushing 21. Thus, since the adjusting member 34 is threadedly engaged with the bushing 21, simply rotating the adjusting member 34 allows it to move up and down along the axis of the bushing 21, resulting in a simple structure and convenient operation.

[0037] Furthermore, an elastic gasket 35 is provided between the adjusting member 34 and the first friction plate 32, with its axial sides abutting against the adjusting member 34 and the first friction plate 32 respectively. Thus, the elastic gasket 35 is elastic, allowing it to apply a gentler pressure to the first friction plate 32, preventing excessively direct pressure from causing structural damage. In this embodiment, the elastic gasket 35 is a butterfly-shaped gasket, which can provide cushioning through its own deformation.

[0038] To make the installation of each structure more stable, a limiting shim 37 is also fixed on the side of the elastic shim 35 away from the first friction plate 32. The limiting shim 37 presses the second friction plate 33, the main rail sprocket 31, the first friction plate 32 and the elastic shim 35, making the device structure more compact.

[0039] The sprocket assembly 30 also includes a bushing 36, which is fitted onto the outer periphery of the bushing 21 and is movably connected to the bushing 21. The main rail sprocket 31 is connected to the outer periphery of the bushing 36. In this way, the bushing 36 acts as an intermediate transition member, making the rotation of the main rail sprocket 31 relative to the bushing 21 smoother and preventing wear on the inner side of the main rail sprocket 31 or the outer side of the bushing 21.

[0040] Of course, in other embodiments, in order to save costs and facilitate assembly, the main rail sprocket 31 can be directly movably connected to the outer periphery of the bushing 21.

[0041] Preferably, in this embodiment, the drive component 11 and the drive shaft 12 are keyed together, and the drive shaft 12 and the bushing 21 are keyed together. Keyed connections provide stable connection during rotation, have a simple structure, and low processing cost.

[0042] The drive unit 100 also includes a first bearing assembly 40 and a second bearing assembly 50. The first bearing assembly 40 includes a first bearing seat 41 and a first fixing plate 42. The first bearing seat 41 is connected to the first fixing plate 42, and the first fixing plate 42 is connected to the main rail profile. The second bearing assembly 50 includes a second bearing seat 51 and a second fixing plate 52. The second bearing seat 51 and the second fixing plate 52 are connected, and the second fixing plate 52 is connected to the main rail profile. The drive shaft 12 passes through the first bearing seat 41 and the second bearing seat 51 and is rotatably connected to them respectively. In this way, the first bearing assembly 40 and the second bearing assembly 50 can guide the rotation of the drive shaft 12, making the rotation of the drive shaft 12 more stable.

[0043] Preferably, one end of the drive shaft 12 is also connected to a support shaft 13. The support shaft 13 and the drive shaft 12 are separately disposed and connected together by screws or welding. The drive shaft 12 passes through the first bearing assembly 40, and the support shaft 13 passes through the second bearing assembly 50.

[0044] In this embodiment, a deep groove ball bearing is installed in the first bearing housing 41, and a tapered roller bearing is installed in the second bearing housing 51. The two bearings with different structures result in different force characteristics in the first bearing housing 41 and the second bearing housing 51, and their cooperation makes the operation of the drive component 11 more stable.

[0045] This utility model also provides a garment hanging production line, including the drive device 100 as described above, as well as a main rail profile and a chain 60, with the chain 60 wound around the sprocket assembly 30.

[0046] Compared to existing technologies, this invention uses a pressure plate 38 and a first friction plate 32 to slidably connect the sprocket assembly 30 and the transmission assembly 20. During normal operation of the garment hanging production line, the friction between the transmission assembly 20 and the sprocket assembly 30 is sufficient to rotate the sprocket assembly 30, thereby driving the chain 60. When the chain 60 or other structures accidentally jam, preventing the sprocket assembly 30 from rotating, the driving force of the drive component 11 is greater than the friction between the sprocket assembly 30 and the transmission assembly 20. Therefore, the drive component 11 can drive the transmission assembly 20 to rotate normally relative to the sprocket assembly 30. Relative friction is generated between the transmission assembly 20 and the sprocket assembly 30, and the system changes to a clutch state, thus preventing the chain 60 from forcibly disengaging from the sprocket. This also provides anti-derailment protection for the main rail sprocket 31 and the chain 60.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
