Description

Technical Field

[0001] The present application relates to the technical field of hanging assembly lines, and in particular to a hanging lifting arm and a hanging assembly line. Background Art

[0002] The hanging and lifting system of the current garment hanging assembly line mainly consists of a storage track assembly for conveying and storing hangers, a lowering stop assembly for blocking and releasing hangers, a lifting assembly, and an exit assembly located downstream of the lifting assembly. The sewing material on the hanger released from the lowering stop assembly to the bottom of the lifting assembly is directly used for sewing. After sewing is completed, the hanger is conveyed by the lifting assembly to the exit assembly, where it falls onto the main track and continues to be transported downstream. At the same time, the lowering stop assembly continues to release new hangers into the lifting assembly, and this cycle repeats.

[0003] When factory workers use garment hanging lines to sew, due to the varying lengths of sewing materials, for longer materials, workers can simply move the materials from the hanger at the lower end of the hanging lifting arm to the sewing table for sewing without having to remove them from the hanger. However, for shorter materials, due to the greater distance between the materials and the sewing table, workers must first remove the materials from the hanger before sewing. After sewing, they must rehang the materials on the hanger to allow them to be transported downstream. Therefore, the placement and removal of the materials affects workers' garment-making efficiency. Furthermore, due to the varying heights and operating habits of workers, the existing hanging lifting arm height and sewing table layout cannot meet the individual needs of all workers, further impacting operational convenience and overall efficiency.

The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0033] See Figures 1 to 7 The present application provides a hanging lifting arm 1, comprising a conveying track for slidingly cooperating with the roller 21 of the hanger 2. The conveying track comprises a feed track 10, a discharge track 20, and a lifting track 30 for conveying the hanger 2 from the feed track 10 to the discharge track 20, wherein the discharge track 20 is located above the feed track 10. The lifting track 30 comprises a lifting section 310 and a lifting section 320 connected in sequence from bottom to top along the conveying direction of the hanger 2. The upper end of the lifting section 320 is connected to the discharge track 20. The lifting section 310 is arranged to be able to move up and down between a first position and a second position relative to the lifting section 320, so that the entry end of the lifting section 310 is connected to or disconnected from the feed track 10.

[0034] Schematically, when the lifting section 310 is in the first position, the entrance end of the lifting section 310 is connected to the feed track 10; when the lifting section 310 moves from the first position to the second position, the lifting section 310 is disconnected from the feed track 10. Alternatively, when the lifting section 310 is in the first position, the lifting section 310 is disconnected from the feed track 10; when the lifting section 310 moves from the first position to the second position, the entrance end of the lifting section 310 is connected to the feed track 10. Alternatively, when the lifting section 310 is in either the first position or the second position, the lifting section 310 is disconnected from the feed track 10; when the lifting section 310 is in a position between the first and second positions, the entrance end of the lifting section 310 is connected to the feed track 10. This embodiment is not limited to this. The following description uses "when the lifting section 310 is in the first position, the entrance end of the lifting section 310 is connected to the feed track 10" as an example.

[0035] It is understood that when the lifting section 310 is connected to the feed track 10, the hanger 2 can enter the lifting section 310 from the feed track 10, allowing the sewing material on the hanger 2 to be used for sewing. When the lifting section 310 moves up and down, the hanger 2 can move up and down with the lifting section 310, causing the distance between the hanger 2 and the sewing table / ground to change. This allows the vertical position of the hanger 2 suspended on the lifting section 310 to be flexibly adjusted, thereby meeting the personalized needs of different workers. In addition, because the vertical position of the hanger 2 suspended on the hanging lifting arm 1 is flexibly adjustable, that is, the distance between the sewing material on the hanger 2 and the sewing table is adjustable, the distance between the sewing material on the hanger 2 and the sewing table can be adjusted to the appropriate distance regardless of the length of the sewing material on the hanger 2. Therefore, workers no longer need to remove the sewing material from the hanger 2 before sewing, thereby improving worker productivity.

[0036] It should be noted that the "connection" between the lifting section 310 and the feed track 10 mentioned above means that: in the vertical direction, the lifting section 310 and the feed track 10 are aligned at the connection point, or the lifting section 310 is slightly lower than the feed track 10; in the axial direction of the feed track 10, the lifting section 310 and the feed track 10 may or may not be in contact, that is, there is a certain gap between them, and this embodiment is not limited to this. As long as the roller 21 of the hanger 2 can move from the feed track 10 to the lifting section 310 of the lifting track 30, it is sufficient.

[0037] In one embodiment, the second position is located below the first position, with reference to Figure 1 and Figure 4 As shown, when the lifting section 310 is in the first position, the entry end of the lifting section 310 is connected to the feed track 10. That is, when the lifting section 310 moves downward from the first position to the second position, the lifting section 310 is disconnected from the feed track 10. Figure 2 and Figure 3 shown.

[0038] It is understandable that the worker's sewing table is set directly on the ground, and the conveyor track is set above the sewing table to fully utilize the space above the sewing table. During the transportation of the hanger 2 and the sewing material set on the hanger 2, in order to prevent the sewing material from obstructing the worker's movement, the hanger 2 is often set at a relatively high position, that is, the conveyor track is often set at a relatively high position. Therefore, for shorter sewing materials, the distance between the sewing material and the sewing table is relatively far. At this time, moving the lifting section 310 downward from the first position to the second position can shorten the distance between the sewing material on the hanger 2 and the sewing table, so that the worker can directly sew without removing the sewing material from the hanger 2.

[0039] The method of using the above-mentioned hanging lifting arm 1 is as follows: when the sewing material on the hanger 2 is far away from the sewing workbench, the worker pulls the hanger 2 downward according to the length of the clothes on the hanger 2 so that the hanger 2 drives the lifting section 310 to descend to a position suitable for sewing, and then the user will move the sewing material that has been moved downward to the appropriate position to carry out sewing operations.

[0040] In one embodiment, the lifting section 310 includes a first pipe section 311. The entrance end of the lifting section 310 is located in the first pipe section 311. The first pipe section 311 is angled with respect to the horizontal and is tilted downward from the entrance end. This allows the rollers 21 of the hanger 2 to slide from the feed track 10 into the first pipe section 311 of the lifting section 310 of the lifting track 30 under the action of gravity.

[0041] In one embodiment, the lifting section 310 further includes a second pipe section 312 that is sequentially connected to the first pipe section 311 along the conveying direction of the hanger 2. The axis of the first pipe section 311 and the axis of the second pipe section 312 form an angle with each other, and the end of the first pipe section 311 away from the second pipe section 312 can be connected to the discharge end of the feed track 10. In this way, when the hanger 2 moves up and down with the upward and downward movement of the lifting section 310, the angle between the first pipe section 311 and the second pipe section 312 can prevent the hanger 2 from sliding off the lifting section 310.

[0042] Schematically, the second pipe section 312 is connected to the lifting section 320, so that the lifting section 310 can move up and down between the first position and the second position relative to the lifting section 320; alternatively, the second pipe section 312 and the lifting section 320 are arranged together inside and outside, and this embodiment does not impose any restrictions on this, as long as the lifting section 310 can move up and down between the first position and the second position relative to the lifting section 320, and the hanger 2 will not slip from the lifting section 310.

[0043] Furthermore, the lifting section 310 also includes a connecting pipe section 313 connecting the first pipe section 311 and the second pipe section 312 along the conveying direction of the hanger 2. The connecting pipe section 313 is arc-shaped, so that the roller 21 of the hanger 2 can move more smoothly between the mutually intersecting first pipe section 311 and the second pipe section 312.

[0044] Further, refer to Figure 2 and Figure 3The second tube section 312 and the lifting section 320 are disposed together inside and outside, allowing the lifting track 30 to extend and retract along its length. Thus, the lifting section 320 limits the movement direction of the second tube section 312, and thus the movement direction of the lifting section 310. This prevents the lifting section 310 from deviating from its direction of movement when moving up and down between the first and second positions. This ensures that the lifting section 310 and the lifting section 320 remain aligned, thus preventing the roller of the hanger 2 from deviating from the conveyor track.

[0045] When the lifting section 310 is in the second position, the second pipe section 312 is still disposed inside and outside the lifting section 320 , thereby preventing the hanger 2 from sliding off the lifting section 310 .

[0046] In this embodiment, if Figure 3 As shown, the lifting section 320 is sleeved on the outer peripheral side of the second pipe section 312. In other embodiments, the second pipe section 312 is sleeved on the outer peripheral side of the lifting section 320, which is not limited in this embodiment.

[0047] In one embodiment, the hanging lifting arm 1 further includes a housing 40. The housing 40 and the lifting rail 30 define a space for the roller 21 of the hanger 2 to move. The housing 40 is provided with a guide rail 410 and a mounting base 420 that slidably engages with the guide rail 410. The mounting base 420 is fixedly connected to the lifting section 310. The extension direction Y of the guide rail 410 is the same as the movement direction of the lifting section 310. In this way, the guide rail 410 can guide and limit the movement direction of the lifting section 310, thereby preventing deviation in the movement of the lifting section 310.

[0048] Schematically, a slider is fixedly connected to the mounting seat 420, and the slider is mounted on the guide rail 410 so that the mounting seat 420 and the guide rail 410 can slide together. A mounting plate 421 is also fixedly connected to the mounting seat 420. The extending direction of the mounting plate 421 is the same as the movement direction of the lifting section 310. The opposite ends of the mounting plate 421 are respectively connected to the mounting seat 420 and the lifting section 310, so that the mounting seat 420 is fixedly connected to the lifting section 310 through the mounting plate 421, thereby reducing the weight on the housing 40.

[0049] In one embodiment, see Figure 5 、 Figure 6 and Figure 7The hanging lifting arm 1 further includes a lock 430, which has a locked state that secures the mounting base 420 to the housing 40 and an unlocked state that releases the locking state of the mounting base 420. When the lock 430 is unlocked, the mounting base 420 is in a movable state, capable of moving along the extension direction Y of the guide rail 410. At this time, the lifting section 310 and the mounting base 420 can move up and down, thereby freely adjusting the distance between the lifting section 310 and the sewing table. When the lock 430 is locked, the lifting section 310 and the mounting base 420 remain fixed to the housing 40, suitable for transporting the hanger 2 on the conveyor track or sewing materials on the hanger 2.

[0050] Furthermore, the housing 40 is provided with a plurality of first limiting portions 401 arranged in sequence along the extension direction Y of the guide rail 410, the lock 430 is provided on the mounting seat 420, the lock 430 is provided with a second limiting portion 431, and the lock 430 is arranged to be able to move back and forth along the first direction X, the first direction X and the extension direction Y of the guide rail 410 form an angle with each other, the first limiting portion 401 is located on the movement path of the second limiting portion 431, so that the second limiting portion 431 is locked with the first limiting portion 401 to put the lock 430 in a locked state; or, the second limiting portion 431 is disengaged from the locked state with the first limiting portion 401, that is, the second limiting portion 431 is separated from the first limiting portion 401 to put the lock 430 in an unlocked state.

[0051] It is understandable that by moving the lock element 430 along the first direction X, the second limiting portion 431 of the lock element 430 and the first limiting portion 401 are switched between the locked state and the separated state, thereby switching the lock element 430 between the locked state and the unlocked state.

[0052] The method of using the lock 430 is as follows: the second limiting portion 431 of the lock 430 is locked with the first limiting portion 401. At this time, the lock 430 is in a locked state, and the lifting section 310 and the mounting seat 420 remain fixed to the shell 40; when the position of the lifting section 310 needs to be changed, the lock 430 is moved along the first direction X to separate the second limiting portion 431 of the lock 430 from the first limiting portion 401, that is, the second limiting portion 431 is disengaged from the locked state with the first limiting portion 401, so that the lock 430 is in an unlocked state. At this time, the lifting section 310 and the mounting seat 420 can move up and down relative to the shell 40.

[0053] Schematic, reference Figure 6The first limiting portion 401 is a convex portion or a concave portion, and the second limiting portion 431 can engage or contact the first limiting portion 401, thereby locking the first limiting portion 401 and the second limiting portion 431. Illustratively, in this embodiment, the locking member 430 is disposed on the mounting base 420 through a clearance hole on the mounting base 420 and can move back and forth along the first direction X relative to the mounting base 420.

[0054] In one embodiment, the hanging lifting arm 1 further includes a drive assembly 440 connected to the mounting base 420 . The drive assembly 440 is connected to the lock 430 and is configured to drive the lock 430 to move along the first direction X. In this way, the drive assembly 440 with an automated function can be integrated into the hanging lifting arm 1 . Since the hanging lifting arm 1 is located at a higher position, the automated drive assembly 440 can automatically switch the lock 430 between the unlocked and locked states, thereby enabling a worker to pull the lifting section 310 up and down between the first position and the second position.

[0055] Furthermore, the drive assembly 440 includes a driver 441 and a first elastic member 442. The power output end of the driver 441 is connected to the lock member 430. The first elastic member 442 acts on the lock member 430 to cause the second limiting portion 431 of the lock member 430 to have a tendency to return to a locked state with the first limiting portion 401. The driver 441 is capable of driving the lock member 430 to move along the first direction X, thereby switching the second driving portion between a locked state and a separated state with the first driving portion, that is, switching the lock member 430 between an unlocked state and a locked state. When the second limiting portion 431 of the lock member 430 is separated from the first limiting portion 401, the first elastic member 442 is compressed. The elastic deformation of the first elastic member 442 stores elastic potential energy. Therefore, the first elastic member 442 can assist the driver 441 in restoring the lock member 430 to a locked state with the first limiting portion 401. In other words, the first elastic member 442 has a tendency to keep the lock member 430 in the locked state.

[0056] In this embodiment, reference Figure 7 The lock member 430 is further provided with a raised portion 432 and a shaft portion 433 for connecting to the power output of the driver 441. The shaft portion 433 extends in the same direction as the first direction X. The second stop portion 431 and the shaft portion 433 are respectively provided on either side of the raised portion 432. The mounting base 420 is further provided with an installation space for accommodating the shaft portion 433. The shaft portion 433 can move within the installation space along the first direction X to lock or separate the second stop portion 431 from the first stop portion 401. The first elastic member 442 is sleeved around the shaft portion 433 and is also accommodated within the installation space of the mounting base 420. The two ends of the first elastic member 442 respectively abut against the inner wall of the installation space and the raised portion 432 to act on the lock member 430.

[0057] Schematically, the driver 441 is a cylinder and the first elastic member 442 is a spring. Since the cylinder and the spring are cheap and easy to obtain, this not only ensures their functions but also reduces the production cost of the suspension lifting arm 1.

[0058] In one embodiment, the housing 40 is provided with a second elastic member 450 that constantly causes the lifting section 310 to return from the second position to the first position. The second elastic member 450 acts on the mounting seat 420. It is understood that during the movement of the lifting section 310 from the first position to the second position, the mounting seat 420 stretches or compresses the second elastic member 450, causing it to elastically deform and storing elastic potential energy in the second elastic member 450. The second elastic member 450, with its elastic potential energy, causes the mounting seat 420 to have a tendency to move upward, that is, to cause the lifting section 310 to have a tendency to return from the second position to the first position. Therefore, when the lifting section 310 is in the second position, the elastic potential energy stored in the second elastic member 450 can reset the lifting section 310 from the second position to the first position. It should be noted that the above process occurs when the lock 430 is unlocked.

[0059] Illustratively, the second elastic member 450 can be installed above or below the mounting base 420. When the second elastic member 450 is installed above the mounting base 420, the second elastic member 450 is stretched during the movement of the lifting section 310 from the first position to the second position. When the second elastic member 450 is installed below the mounting base 420, the second elastic member 450 is compressed during the movement of the lifting section 310 from the first position to the second position, enabling the second elastic member 450 to reset the lifting section 310 from the second position to the first position. Illustratively, there are two second elastic members 450, one at each end of the mounting base 420, to ensure a more balanced movement direction during the reset process of the mounting base 420 and prevent deviation.

[0060] In one embodiment, the housing 40 is provided with a stopper 460, which is located at the top of the mounting seat 420. When the lifting section 310 is in the first position, the stopper 460 abuts the mounting seat 420. When the lifting section 310 is in the first position, the entry end of the lifting section 310 is connected to the feed track 10. Therefore, when the lifting section 310 moves upward from the second position, the mounting seat 420 and the lifting section 310 move upward synchronously until they abut against the stopper 460. The lifting section 310 and the mounting seat 420 stop moving upward, and the lifting section 310 returns to the first position. In this way, the stopper 460 facilitates the positioning and resetting of the lifting section 310.

[0061] Illustratively, there are two limiters 460 in this embodiment to enhance the deceleration and buffering effect on the mounting base 420. In other embodiments, one or more limiters 460 may be used as long as they can provide a buffering effect on the rapid reset of the mounting base 420.

[0062] Schematically, the limit member 460 in this embodiment uses a hydraulic buffer, which relies on hydraulic damping to buffer and decelerate the mounting seat 420 acting thereon to a stop, thereby providing a certain degree of protection and preventing damage to the suspension lifting wall caused by hard collision.

[0063] The above-mentioned hanging lifting arm 1 is used as follows: the second stopper 431 of the lock 430 is locked with the first stopper 401 of the housing 40, and the lock 430 is in the locked state. At this time, the lifting section 310 and the lifting section 320 of the lifting track 30 remain fixed, and the lifting section 310 is connected to the feed track 10, allowing the hanger 2 to move on the conveyor track via the roller 21. When the hanger 2 enters the sewing waiting point at the lifting section 310 from the feed track 10, the user presses the switch of the driver 441 to drive the driver 441 to move the lock 430 in the first direction, i.e., move the lock 430 away from the first stopper 401, thereby separating the second stopper 431 of the lock 430 from the first stopper 401 (and during this process, the lock 430 compresses the first elastic member 442), and the lock 430 is unlocked. At this time, the lifting section 310 and the mounting seat 420 can move up and down along the guide rail 410. The user pulls the hanger 2 downward according to the length of the sewing material on the hanger 2 or his or her own requirements for the sewing material position, so that the hanger 2 drives the lifting section 310 down to a position suitable for sewing.

[0064] Because the lifting section 310 and the mounting base 420 are fixedly connected, when the lifting section 310 moves downward, the mounting base 420 also moves downward synchronously, continuously stretching the second elastic member 450. When the hanger 2 and the lifting section 310 are lowered to a suitable position for sewing, the switch of the driver 441 is released to cause the driver 441 to drive the locking member 430 to move in the first direction. At this time, the locking member 430 moves closer to the first limiting portion 401, and the elastic potential energy generated by the compression of the first elastic member 442 assists the locking member 430 in moving closer to the first limiting portion 401, thereby causing the second limiting portion 431 of the locking member 430 to lock with the first limiting portion 401, placing the locking member 430 in a locked state. At this point, the lifting section 310 is in the second position with a relatively lowered height, and the user can sew the sewing material that has been moved downward to the appropriate position.

[0065] After sewing is complete, the user presses the switch of the driver 441 again to disengage the second stopper 431 of the lock member 430 from the first stopper 401 of the housing 40, even if the lock member 430 is in the unlocked state. Since the second elastic member 450 is now in a stretched state, it stores elastic potential energy. This elastic potential energy enables the mounting seat 420 to move upward along the guide rail 410, thereby returning the lifting section 310 from the second position to the first position. The stopper 460 disposed above the mounting seat 420 provides a certain degree of cushioning for the rapid return of the mounting seat 420. After the lifting section 310 returns to the first position, the user releases the switch of the driver 441 again, causing the driver 441 to drive the second stopper 431 of the lock member 430 back to its locked state with the first stopper 401, even if the lock member 430 is in the locked state. At this point, the lifting section 310 returns to its first position, where it is connected to the feed track 10. The motor on the hanging lifting arm 1 drives the belt to drive the hanger 2 to move upward on the lifting section 320 until the hanger 2 is transported to the discharge track 20 and out of the station. Subsequent new hangers 2 continue to be released through the feed track 10 to the sewing waiting area on the lifting section 310 of the lifting track 30 and then start sewing, and this cycle is repeated.

[0066] The user only needs to manually pull the hanger 2 according to the length of the sewing material on the hanger 2 to adjust the upper and lower positions of the sewing points in real time, so as to facilitate sewing and greatly improve sewing efficiency.

[0067] The present application also provides a hanging assembly line, including the hanging lifting arm 1 described in any of the above embodiments. It will be appreciated that, because the distance between the hanging lifting arm 1 and the sewing table is flexibly adjustable, the hanging lifting arm 1 can not only meet the individual needs of all workers but also improve their production efficiency. Therefore, a hanging assembly line including the hanging lifting arm 1 can also meet the individual needs of all workers and improve production efficiency.

[0068] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0069] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
