Description

Technical Field

[0001] This utility model relates to the field of garment processing, and in particular to a protective 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] To address the aforementioned technical problems, this utility model provides a protective device and its garment hanging production line.

[0005] A protective device, applied in a garment hanging production line, includes: a fixed base, fixedly connected to a main rail profile; a movable seat, movably connected to the fixed base and capable of rotating relative to the fixed base between a preset first position and a second position; a driving member, connected to the movable seat, one end of the driving member having a main rail sprocket for driving a chain; an elastic member, one end connected to the fixed base and the other end connected to the movable seat; and a trigger member, installed on the fixed base and electrically connected to the driving member, abutting against the trigger member when the movable seat is in the second position.

[0006] In this configuration, the fixed base is connected to the main rail profile, maintaining a fixed position. The movable seat is connected to the fixed base and remains stationary in the first position when no force is applied. The drive unit is mounted on the movable seat and drives the main rail sprocket to rotate. The main rail sprocket drives the chain to rotate. The elastic element is connected to the movable seat, constantly applying tension to stabilize it in the first position. When the chain jams in the production line, it means the main rail sprocket can no longer rotate. At this time, the drive unit will continue to drive the main rail sprocket to rotate, but since the main rail sprocket is limited by the chain and can no longer rotate, the driving force of the drive unit will react on the movable seat. When the driving force is large, it will overcome the tension of the elastic element on the movable seat, causing the movable seat to rotate from the first position to the second position and contact the trigger element. The trigger element controls the drive unit to stop operating via an electrical signal, preventing problems such as the chain coming off the production line.

[0007] In one embodiment, the movable seat includes a support flange and a rotating plate, the rotating plate being connected to the support flange, and the end of the rotating plate away from the support flange being connected to the elastic element.

[0008] In one embodiment, the rotating plates are configured as two pieces and are respectively connected to opposite sides of the supporting flange, and the elastic elements are configured as two pieces and are respectively connected to the two rotating plates.

[0009] In one embodiment, the movable seat further includes a connector, and the fixed base has a connecting hole. Along the rotation direction of the movable seat, the length of the connecting hole is greater than the outer diameter of the connector, and when the connector moves from one end of the connecting hole to the other end, the movable seat rotates from the first position to the second position.

[0010] In one embodiment, the fixed base has a first side and a second side facing away from each other, and the drive member passes through the fixed base and extends from the first side to the second side;

[0011] The driving component includes a driving source and a driving shaft. The driving source is located on the first side, and the driving shaft is connected to the driving component and extends to the second side. The protection device also includes a first bearing housing, which is connected to the main rail profile. The driving shaft passes through the first bearing housing and is rotatably connected to the first bearing housing.

[0012] In one embodiment, a first fixing plate is provided on the outer side of the first bearing housing, and the first fixing plate is connected to the main rail profile; the drive shaft is keyed to the main rail sprocket.

[0013] In one embodiment, the protective device further includes a second bearing housing, a second fixing plate is provided on the outer side of the second bearing housing, the second fixing plate is connected to the main rail profile, and a support shaft is provided inside the second bearing housing, the support shaft being connected to the drive shaft.

[0014] In one embodiment, the movable seat further includes a fixed flange, the side of which away from the fixed base is configured as a disc structure and connected to the drive source.

[0015] In one embodiment, the fixed base is provided with a mounting plate, the mounting plate is set at an angle to the fixed base, and the elastic element is connected to the mounting plate.

[0016] In one embodiment, the device includes the protective device described above, as well as a main rail profile and a chain, the chain being wound around the main rail sprocket.

[0017] Compared to existing technologies, this invention uses a drive component to drive the main rail sprocket to rotate. The drive component is mounted on a movable seat, which can rotate within a certain angle relative to the fixed base. An elastic element is provided to hold the movable seat in its initial position. When the chain jams and the main rail sprocket cannot rotate, the driving force applied by the drive wheel to the main rail sprocket will react on the movable seat and cause it to rotate in the opposite direction. This overcomes the tension of the elastic element and triggers the trigger element mounted on the fixed base, causing the drive seat to stop rotating and preventing damage to the production line.

[0027] This utility model provides a protective device 100, which is applied in a garment hanging production line. When the chain in the production line gets stuck, the drive component 30 continuously applies a force to the main rail sprocket 60. The resulting reaction force can push the movable seat 20 to rotate and contact the trigger component 50. The trigger component 50 controls the drive component 30 to stop rotating through an electrical signal to prevent damage to the production line.

[0028] Please see Figures 1-2The protection device 100 includes a fixed base 10, a movable seat 20, a driving member 30, an elastic member 40, and a trigger member 50. The fixed base 10 is fixedly connected to the main rail profile. The movable seat 20 is movably connected to the fixed base 10 and can rotate relative to the fixed base 10 between a preset first position and a second position. The driving member 30 is connected to the movable seat 20, and one end of the driving member 30 is provided with a main rail sprocket 60 for driving the chain. One end of the elastic member 40 is connected to the fixed base 10, and the other end is connected to the movable seat 20. The trigger member 50 is installed on the fixed base 10 and electrically connected to the driving member 30. When the movable seat 20 is in the second position, it abuts against the trigger member 50. Thus, the fixed base 10 is connected to the main rail profile, and its position remains fixed. The movable seat 20 is connected to the fixed base 10 and will remain stationary in the first position when it is not under force. The drive component 30 is installed on the movable seat 20 and drives the main rail sprocket 60 to rotate. The main rail sprocket 60 drives the chain to rotate. The elastic component 40 is connected to the movable seat 20 and always applies a pulling force to the movable seat 20, stabilizing it in the first position. When the chain jams in the production line, it means that the main rail sprocket 60 can no longer rotate. At this time, the drive component 30 will continue to drive the main rail sprocket 60 to rotate. However, the main rail sprocket 60 is limited by the chain and can no longer rotate. Therefore, the driving force of the drive component 30 will react on the movable seat 20. When the driving force is large, it will overcome the pulling force of the elastic component 40 on the movable seat 20, causing the movable seat 20 to rotate from the first position to the second position and contact the trigger component 50. The trigger component 50 controls the drive component 30 to stop operating through electrical signal transmission, preventing problems such as the chain coming off the production line.

[0029] It should be explained that the main rail profile, as the supporting structure of the garment hanging production line, is installed on the ground and its position remains fixed. The main rail sprocket 60 drives the chain (not shown in the figure), which is used to drive the movement of garments on the garment hanging production line.

[0030] Furthermore, the movable seat 20 includes a support flange 21 and a rotating plate 22. The rotating plate 22 is connected to the support flange 21, and one end of the rotating plate 22 away from the support flange 21 is connected to the elastic element 40. Thus, the support flange 21 is used to connect to the fixed base 10, and the rotating plate 22 extends radially outward, with one outer end used to connect to the elastic element 40. Its longer torque facilitates the elastic element 40 applying tension to the movable seat 20.

[0031] Preferably, two rotating plates 22 are provided, and are respectively connected to opposite sides of the supporting flange 21. Two elastic elements 40 are provided, and are respectively connected to the two rotating plates 22. In this way, the supporting flange 21 is subjected to balanced forces, and is subjected to equal tensile forces from the elastic elements 40 in two opposite directions.

[0032] In this embodiment, the elastic element 40 is configured as a spring structure. The rotating plate 22 is configured with a near-triangular structure, with its width wider on the side closer to the supporting flange 21 to ensure strength.

[0033] The movable seat 20 also includes a connector. The fixed base 10 has a connecting hole. Along the rotation direction of the movable seat 20, the length of the connecting hole is greater than the outer diameter of the connector. When the connector moves from one end of the connecting hole to the other, the movable seat 20 rotates from a first position to a second position. Thus, the movable seat 20 is connected to the fixed base 10 via the connector. Because the length of the connecting hole is greater than the outer diameter of the connector, there is a gap between the hole wall and the connector, allowing the connector to move within the connecting hole, thereby enabling the movable seat 20 to switch between the first and second positions.

[0034] In this embodiment, the connector is a screw; in other embodiments, it can also be a bolt or other structure.

[0035] The fixed base 10 has a first side and a second side facing away from each other. A drive member 30 passes through the fixed base 10 and extends from the first side to the second side. The drive member 30 includes a drive source 31 and a drive shaft 32. The drive source 31 is located on the first side, and the drive shaft 32 is connected to the drive member 30 and extends to the second side. The protective device 100 also includes a first bearing housing 70, which is connected to the main rail profile. The drive shaft 32 passes through the first bearing housing 70 and is rotatably connected to it. Thus, the drive source 31 outputs power through the drive shaft 32, which extends to the second side, and the first bearing housing 70 is also installed on the second side, making full use of space. Furthermore, the first bearing housing 70 enables the rotation of the drive shaft 32 to be more stable.

[0036] Specifically, the drive shaft 32 is keyed to the main rail sprocket 60 to achieve stable power transmission. In other embodiments, the connection can also be achieved by welding or other methods.

[0037] It should be explained that the key connection refers to the presence of a connecting key protruding on the drive shaft 32 and a connecting groove constructed on the inner side of the main rail sprocket 60, with the connecting key embedded in the connecting groove, so that the drive shaft 32 can drive the main rail sprocket 60 to rotate.

[0038] A first fixing plate 71 is provided on the outer side of the first bearing housing 70. The first fixing plate 71 is connected to the main rail profile to ensure the stable installation of the first bearing housing 70.

[0039] The protective device 100 also includes a second bearing housing 80. A second fixing plate 81 is provided on the outer side of the second bearing housing 80, and the second fixing plate 81 is connected to the main rail profile. A support shaft 82 is provided inside the second bearing housing 80, and the support shaft 82 is connected to the drive shaft 32. In this way, the support shaft 82 is connected to the drive shaft 32, and the rotation limit of the second bearing housing 80 on the support shaft 82 is also the rotation limit of the drive shaft 32. Therefore, during the operation of the drive component 30, it actually has the combined limiting effect of two bearing housings, the first bearing housing 70 and the second bearing housing 80, resulting in more stable operation.

[0040] Preferably, in this embodiment, a deep groove ball bearing is disposed in the first bearing housing 70, and a tapered roller bearing is disposed in the second bearing housing 80. The two bearings with different structures result in different force characteristics of the first bearing housing 70 and the second bearing housing 80, and their cooperation makes the operation of the drive component 30 more stable.

[0041] The movable base 20 also includes a fixed flange 23. The side of the fixed flange 23 away from the fixed base 10 is configured as a disc structure and connected to the drive source 31. The side of the fixed flange 23 closer to the fixed base 10 is connected to the support flange 21. In this way, the drive component 30 is connected to the support flange 21 through the fixed flange 23. The fixed flange 23 serves as an intermediate transition piece, facilitating the connection between the drive component 30 and the support flange 21.

[0042] Furthermore, a flange 33 is also provided on the outer periphery of the drive component 30, and multiple connection holes are opened on the flange 33. It is connected to the disc structure of the fixed flange 23 by screws, thereby strengthening the connection strength between the drive component 30 and the fixed flange 23.

[0043] A mounting plate 11 is provided on the fixed base 10, and the mounting plate 11 is set at an angle to the fixed base 10. An elastic element 40 is connected to the mounting plate 11. This facilitates the installation of the elastic element 40, which can be stretched or shortened along a direction parallel to the surface of the first side of the fixed base 10. Preferably, the mounting plate 11 is perpendicular to the surface of the fixed base 10.

[0044] This utility model also provides a garment hanging production line, including the protective device 100 as described above, as well as a main rail profile and a chain, with the chain wrapped around the main rail sprocket 60.

[0045] In this application, the drive component 30 is set as an asynchronous motor, and the trigger component 50 is set as a stop switch. The working logic is as follows: detect whether the stop switch is triggered. When it is not triggered, the device operates normally. When the stop switch is triggered, the signal is uploaded to the control center, the control center controls the asynchronous motor to cut off the power, and the upper alarm device then prompts that the motor is stalled.

[0046] Compared to existing technologies, this invention uses a drive component 30 to drive the main rail sprocket 60 to rotate. The drive component 30 is mounted on the movable seat 20, which can rotate relative to the fixed base 10 within a certain angle. An elastic element 40 is provided to hold the movable seat 20 in its initial position. When the chain jams and the main rail sprocket 60 cannot rotate, the driving force applied by the drive wheel to the main rail sprocket 60 will react on the movable seat 20 and cause the movable seat 20 to rotate in the opposite direction. This overcomes the tension of the elastic element 40 and triggers the trigger element 50 mounted on the fixed base 10, causing the drive seat to stop rotating and preventing damage to the production line.

[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.
