Description

Technical Field

[0001] This utility model relates to the field of garment production line technology, and in particular to a stop mechanism. Background Technology

[0002] In the common garment hanging production lines on the market, the hangers follow the hanger wheels on the main rail. During the process from the high point to the low point of the main rail, they often pass through the blocking and release mechanism. When the blocking and release mechanism blocks the hanger wheels, due to the potential energy of the hanger itself, after the position of the hanger wheels is limited, the hanger on the lower side will sway forward due to inertia. This often causes hanger jamming, cross-hanging, double hanger and other phenomena with the hangers that have been released in front. Adjacent hanger bodies cross and embed themselves, and the whole is directly jammed. This not only reduces the overall efficiency, but also affects the stability of operation. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a stopping mechanism.

[0004] A stop mechanism is applied in a garment hanging production line. The stop mechanism includes: a base assembly, a frame fixedly connected to the garment hanging production line; a main rail for supporting a hanger wheel, the main rail passing through the base assembly, and a hanger connected to the hanger wheel; and a stop assembly connected to the base assembly. The stop assembly includes a first stop unit and a second stop unit. At least a portion of the first stop unit is located within the base assembly and is movable to abut against the hanger wheel, stopping the hanger wheel in a first position or a second position. The second stop unit is connected to the lower side of the base assembly and is movable to stop the hanger in a third position or a fourth position. Along the forward direction of the hanger wheel, the first position and the second position are spaced apart, and the third position and the fourth position are spaced apart. In the vertical direction, the first position is above the third position, and the second position is above the fourth position.

[0005] With this configuration, the hanger wheel moves along the main rail within the base assembly. The first stop unit is located within the base assembly and can abut and limit the hanger wheel. The hanger hangs on the hanger wheel, and its movement trajectory is located on the lower side of the base assembly. The second stop unit located on the lower side of the base assembly can limit the hanger wheel. By staggering and associating the stop positions of the hanger wheel and hanger rod in space (in the forward direction and vertical direction), coordinated and layered stops for the hanger and its hanger wheel are achieved. This effectively prevents the risk of the hanger colliding or crossing with the hanger in front due to inertial forward swaying, thus improving the operational stability and efficiency of the hanging production line.

[0006] In one embodiment, the first stop unit includes a first drive member and a pawl, the first drive member being connected to the base assembly, the pawl being rotatably connected to the base assembly, and a portion of the pawl being located within the base assembly, the base assembly being capable of driving the pawl to rotate.

[0007] In one embodiment, the second stop unit includes a first stop and a second stop, which are synchronously linked. When one of the first stop and the second stop extends into the movement path of the hanger and the other exits from the movement path, the first stop can stop the hanger in a third position, and the second stop can stop the hanger in a fourth position.

[0008] In one embodiment, the second stop unit further includes a second driving member, which is connected to the base assembly, and one end of the second driving member is provided with a first rotating shaft, wherein the first stop rod and the second stop rod are rotatably connected to the first rotating shaft.

[0009] In one embodiment, a fixed seat is provided at the bottom of the base assembly, the first stop includes a drive section and a stop section, the drive section and the stop section are connected and set at an angle, one end of the drive section is connected to the second drive member, and the other end is provided with a positioning shaft, the positioning shaft is rotatably connected to the fixed seat.

[0010] In one embodiment, the stop section is configured as an L-shaped structure, and both the stop section and the drive section are provided with grooves.

[0011] In one embodiment, the second stop unit further includes a linkage rod, one end of which is rotatably connected to the fixed base and the other end of which is rotatably connected to the middle position of the second stop bar. The second stop bar is configured to follow a curved path during movement. The curved path includes a section that climbs from the left to the right and then folds back in the direction of travel of the hanger, so that the second stop bar avoids the hanger when it extends into the movement path.

[0012] In one embodiment, a second rotating shaft and a third rotating shaft are respectively provided at both ends of the linkage rod. The second rotating shaft is rotatably connected to the fixed base, and the third rotating shaft is rotatably connected to the second stop. The fixed base includes a base plate, a first bracket and a second bracket. The first bracket is rotatably connected to the first stop, and the second bracket is rotatably connected to the second rotating shaft. The first bracket and the second bracket are spaced apart. The base plate, the first bracket and the second bracket are integrally formed.

[0013] In one embodiment, the linkage rod includes a first segment and a second segment, which are staggered along the axial direction of the second rotating shaft to form a stepped structure. The second stop rod includes a third segment and a fourth segment, which are staggered along the axial direction of the second rotating shaft to form a stepped structure.

[0014] In one embodiment, the stop mechanism further includes a sensor connected to the base assembly, capable of detecting whether there is a hanger wheel at the first position, triggering the first stop unit to move to release the stop on the hanger wheel, and triggering the second stop unit to move to release the stop on the hanger.

[0015] In one embodiment, the first stop unit includes a first drive member, the second stop unit includes a second drive member, the first drive member and the second drive member are cylinders, the stop mechanism further includes a control unit, the control unit is connected to the first drive member and the second drive member through a solenoid valve and an air pipe to make the first drive member and the second drive member move synchronously, the air pipe includes a connector, the connector diverts the airflow from the solenoid valve to the first drive member and the second drive member.

[0016] Compared to existing technologies, this invention, by setting up a first stop unit and a second stop unit that operate synchronously, allows both to simultaneously stop the hanger wheels and hangers on both the upper and lower layers. This effectively prevents the risk of hangers colliding or crossing with hangers in front due to inertial forward swaying, thus improving the operational stability and efficiency of the hanging production line. Furthermore, the structural design of the second stop unit has been specifically optimized, enabling the first and second stop levers to stably and efficiently stop the hangers, with a short movement path, good stopping effect, and avoidance of interference.

[0032] This utility model provides a stop mechanism 100, which is applied in a garment hanging production line. It has a first stop unit 30 and a second stop unit 40. The first stop unit 30 is located inside the base assembly 10 and is used to stop the hanger wheel 102. The second stop unit 40 is located on the lower side of the base assembly 10 and is used to stop the hanger 103. Therefore, when the hanger wheel 102 is stopped, the hanger 103 will also be stopped by the second stop unit 40, and there will be no problem of forward wobbling.

[0033] Please see Figures 1-3The stop mechanism 100 includes a base assembly 10, a main rail 20, and a stop assembly. The base assembly 10 is fixedly connected to the frame 101 in the garment hanging production line. The main rail 20 is used to support the hanger wheel 102 and passes through the base assembly 10. The hanger wheel 102 is connected to the hanger 103. The stop assembly is connected to the base assembly 10 and includes a first stop unit 30 and a second stop unit 40. At least a portion of the first stop unit 30 is located inside the base assembly 10 and can move to abut against the hanger wheel 102 and stop the hanger wheel 102 in a first position or a second position. The second stop unit 40 is connected to the lower side of the base assembly 10 and can move to stop the hanger 103 in a third position or a fourth position. Along the forward direction of the hanger wheel 102, the first position and the second position are spaced apart, and the third position and the fourth position are spaced apart. In the vertical direction, the first position is above the third position, and the second position is above the fourth position. Thus, the hanger wheel 102 moves along the main rail 20 within the base assembly 10. The first stop unit 30 is located within the base assembly 10 and can abut and limit the hanger wheel 102. The hanger 103 is hung on the hanger wheel 102, and its movement trajectory is located on the lower side of the base assembly 10. The second stop unit 40 located on the lower side of the base assembly 10 can limit the hanger wheel 102. By staggering and associating the stop positions of the hanger wheel 102 and the hanger 103 rod in space (forward direction and vertical direction), coordinated and layered stops for the hanger 103 and its hanger wheel 102 are achieved. This effectively prevents the risk of the hanger 103 colliding or crossing with the hanger 103 in front due to inertial forward swaying, thus improving the operational stability and efficiency of the hanging production line.

[0034] Specifically, the first stop unit 30 includes a first drive member 31 and a pawl 32. The first drive member 31 is connected to the base assembly 10, and the pawl 32 is rotatably connected to the base assembly 10, with a portion of the pawl 32 located within the base assembly 10. The base assembly 10 can drive the pawl 32 to rotate. Thus, by precisely controlling the rotation of the pawl 32 through the first drive member 31, the blocking and releasing of the hanger wheel 102 between the first and second positions can be reliably achieved, with accurate action and a simple and reliable structure.

[0035] In this embodiment, the first driving member 31 is a cylinder. The extension and retraction of the cylinder drives the claw 32 to rotate relative to the base assembly 10. The rotation of the claw 32 enables the engagement or release of the hanger wheel 102.

[0036] The chuck 32 includes a first chuck body 321 and a second chuck body 322, which are angled together. (See [link to relevant documentation]). Figure 2When the cylinder extends and the pawl 32 rotates clockwise, the first pawl 321 lifts up and the second pawl 322 moves downward to engage the hanger wheel 102. When the cylinder retracts and the pawl 32 rotates counterclockwise, the second pawl 322 lifts up, the hanger wheel 102 is released, and the first pawl 321 moves downward to engage the next hanger wheel 102.

[0037] Please see Figures 4-5 The second stop unit 40 includes a first stop lever 41 and a second stop lever 42. The first stop lever 41 and the second stop lever 42 can be linked synchronously. When one of the first stop lever 41 and the second stop lever 42 extends into the movement path of the hanger 103 and the other retracts from the movement path, the first stop lever 41 can stop the hanger 103 in a third position, and the second stop lever 42 can stop the hanger 103 in a fourth position. In this way, through this forward and backward linkage design, it is ensured that the two functional modes of anti-forward swaying (the first stop lever 41) and anti-reverse collision (the second stop lever 42) can be seamlessly and quickly switched. This not only prevents the current hanger 103 from swaying forward, but also blocks the subsequent hangers 103 from rushing forward, avoiding interference problems caused by the continuous sliding of hangers 103. When the first driving member 31 extends and the second claw body 322 limits the hanger wheel 102, the first stop bar 41 also extends to limit the hanger 103 hanging on the hanger wheel 102. When the second claw body 322 releases the hanger wheel 102 and the first pawl 32 moves downward to limit the hanger wheel 102, the first stop bar 41 retracts and the second stop bar 42 extends, similarly limiting the hanger 103 located below the hanger wheel 102 that is now limited.

[0038] Specifically, the second stop unit 40 further includes a second driving member 43, which is connected to the base assembly 10. One end of the second driving member 43 is provided with a first rotating shaft 431, and both the first stop lever 41 and the second stop lever 42 are rotatably connected to the first rotating shaft 431. In this way, the first stop lever 41 and the second stop lever 42 can be driven to move simultaneously through the second driving member 43 and the shared first rotating shaft 431, which simplifies the drive source and transmission structure, reduces cost and control complexity, and ensures strict synchronization of the movement of the two stop levers.

[0039] In this embodiment, the second driving member 43 in the second stop unit 40 is also configured as a cylinder, and the cylinder drives the first stop lever 41 and the second stop lever 42 to move synchronously by extending and retracting.

[0040] A fixed seat 11 is provided at the bottom of the base assembly 10. The first stop lever 41 includes a drive section 411 and a stop section 412. The drive section 411 and the stop section 412 are connected and set at an angle. One end of the drive section 411 is connected to the second drive member 43, and the other end is provided with a positioning shaft 413. The positioning shaft 413 is rotatably connected to the fixed seat 11. In this way, a design that tends to be a lever structure is formed. The lever structure design efficiently converts the linear motion of the drive member into the swing motion of the stop section 412 in the movement path, increases the lever arm, and makes the action more effortless and the response faster. At the same time, the positioning shaft 413 provides a stable rotation fulcrum, ensuring the accuracy of the motion trajectory.

[0041] Preferably, the stop section 412 is configured with an L-shaped structure, and both the stop section 412 and the drive section 411 are provided with grooves 414. In this way, the L-shaped structure can better adapt to the shape of the clothes hanger 103 rod, achieving effective hooking and blocking; while the design of the grooves 414 can reduce the weight of the entire stop rod, reduce the moment of inertia, make the action more sensitive, and save materials and reduce costs while ensuring structural strength.

[0042] Furthermore, the second stop unit 40 also includes a linkage rod 44, one end of which is rotatably connected to the fixed base 11, and the other end is rotatably connected to the middle position of the second stop rod 42. The second stop rod 42 is configured to follow a curved path during movement. The curved path includes a section that rises from the left side to the right side and then folds back in the forward direction of the hanger 103, so that the second stop rod 42 avoids the hanger 103 when it extends into the moving path. See also... Figure 6 and Figure 7 The linkage rod 44, the fixed base 11, and the second stop rod 42 form a linkage mechanism. The linkage rod 44 can guide the movement direction and trajectory of the second stop rod 42. This mechanism constrains the second stop rod 42 to follow an optimized trajectory of first climbing to avoid the obstacle and then turning back to block it. This trajectory ensures that the second stop rod 42 effectively avoids the movement space of the hanger 103 rod when it extends into the path to block the hanger 103 rod, thereby completely avoiding the risk of collision or jamming with the hanger 103 rod during the operation.

[0043] Please participate Figure 7 The diagram shows the trajectory of the second stop lever 42. The path from point A to point B is not a straight line, but a curve that gradually rises from left to right and then curves back. This curve avoids the hanger bar above point A. Whether the hangers 103 are stacked or single hangers 103 are falling continuously, the second stop lever 42 will not hit the hangers 103 during its extension and retraction, thus preventing the hangers 103 from getting stuck. Simultaneously, the folding section ( Figure 7The trajectory selected at point B in the middle can quickly increase the distance in the Y direction to block the clothes hanger 103, but the distance decreases when the X direction is increased. Therefore, the second stop lever 42 does not need a large stroke, and the stroke of the cylinder can fully meet the linkage effect.

[0044] It should be explained that the X direction refers to the forward direction of the hanger wheel 102, and the Y direction is the horizontal direction perpendicular to the X direction.

[0045] The two ends of the linkage rod 44 are respectively provided with a second rotating shaft 441 and a third rotating shaft 442. The second rotating shaft 441 is rotatably connected to the fixed base 11, and the third rotating shaft 442 is rotatably connected to the second stop rod 42. The fixed base 11 includes a base plate 113, a first bracket 111, and a second bracket 112. The first bracket 111 is rotatably connected to the first stop rod 41, and the second bracket 112 is rotatably connected to the second rotating shaft 441. The first bracket 111 and the second bracket 112 are spaced apart. The base plate 113, the first bracket 111, and the second bracket 112 are integrally formed. In this way, a stable rotary pair system is formed by multiple rotating shafts and spaced-apart brackets, ensuring the smoothness and accuracy of the linkage motion. The integrally formed fixed base 11 enhances the rigidity and strength of the entire support structure, ensuring accurate positioning of each moving part during long-term use and preventing deformation.

[0046] Understandably, in other embodiments, the fixing base 11 can also be formed by processing the base plate 113, the first bracket 111 and the second bracket 112 separately and then assembling and welding them together, and is not limited to an integrally formed structure.

[0047] The linkage 44 includes a first segment 443 and a second segment 444, which are staggered along the axial direction of the second rotating shaft 441 to form a stepped structure. The second stop 42 includes a third segment 421 and a fourth segment 422, which are also staggered along the axial direction of the second rotating shaft 441 to form a stepped structure. This optimizes the layout of components within a limited space, preventing interference between the linkage 44, the stop, and other adjacent components during complex movements, resulting in a more compact mechanism and smoother movement.

[0048] The stopping mechanism 100 also includes a sensor connected to the base assembly 10. The sensor can detect whether there is a hanger wheel 102 at the first position, and trigger the first stopping unit 30 to move to release the stop on the hanger wheel 102, and trigger the second stopping unit 40 to move to release the stop on the hanger 103. In this way, the stopping process is automated. The sensor automatically detects the hanger 103 in place signal and triggers the two stopping units to work together to switch between allowing and blocking.

[0049] Please see Figure 8When the first driving element 31 and the second driving element 43 are cylinders, the stop mechanism 100 also includes a control unit. The control unit is connected to the first driving element 31 and the second driving element 43 through a solenoid valve 50 and an air pipe 51 to ensure synchronous movement of the first driving element 31 and the second driving element 43. The air pipe 51 includes a connector 52, which diverts the airflow from the solenoid valve 50 to the first driving element 31 and the second driving element 43. Thus, using cylinders as driving elements provides strong and rapid linear power, which is very suitable for this type of blocking action that requires frequent and rapid start-stop. The cylinders ensure synchronous movement of the first stop unit 30 and the second stop unit 40 from the air source, ensuring that the hanger wheel 102 and the hanger 103 rod are always in the correct state of simultaneous resistance and release, thereby solving the problem of the hanger 103 wobbling forward and crossing. At the same time, this solution has a simple structure, low cost, and concise control logic, reducing the system's failure rate and maintenance costs.

[0050] Of course, it is understandable that in other embodiments, the simultaneous operation of the first drive unit 31 and the second drive unit 43 can also be achieved through other electronic control schemes.

[0051] Preferably, in this embodiment, the connector 52 is a Y-shaped connector 52 to achieve connection between one air tube 51 and two air tubes 51.

[0052] Compared to existing technologies, this invention, by setting up a first stop unit 30 and a second stop unit 40 that operate synchronously, allows both units to simultaneously stop the hanger wheel 102 and the hanger 103 on both the upper and lower levels. This effectively prevents the risk of the hanger 103 colliding or crossing with the hanger 103 in front due to inertial forward swaying, thus improving the operational stability and efficiency of the hanging production line. Furthermore, the structural design of the second stop unit 40 has been specifically optimized, allowing the first stop lever 41 and the second stop lever 42 to stably and efficiently stop the hanger 103, with a short movement path, good stopping effect, and avoidance of interference.

[0053] 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.

[0054] 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.
