Description

Technical Field

[0001] This invention relates to a multi-specification rope embroidery device. Background Technology

[0002] Rope embroidery uses rope as a decoration, sewing it onto fabric. To enrich the design, multiple rope embroidery pieces are often combined to create multi-colored rope embroidery.

[0003] The earlier application CN202211287803.0 discloses a multi-specification rope embroidery device, which sets the loop heads of the rope feeders of two or more rope embroidery components on a loop head base. Each rope embroidery component includes an independent motor that drives the corresponding rope swing and loop head. The loop head and the drive motor are transmitted through a synchronous belt pulley assembly. As the number of loop heads on the loop head base increases, in order to ensure that the transmission path does not affect the use of other functional mechanisms, the synchronous belt drive needs to be equipped with a steering wheel and a tension wheel. The more loop heads there are, the more complex the transmission becomes. This structure can usually only set three sets for multi-color rope embroidery, and can barely be set to four sets at its limit.

[0004] Each group of rope embroidery components has an independent drive motor for its rope feeder (rope feeding and taking in mechanism), which results in a large rope feeder size. This makes it inconvenient to arrange more than three groups in a compact layout. According to the existing embroidery machine structure, the number of rope feeders should not exceed three; otherwise, the rational layout of the entire device would have to be greatly sacrificed.

[0005] Therefore, the existing multi-specification rope embroidery devices require two motors for each group of rope embroidery components, and six motors for three groups. The large number of motors used results in high costs, and also leads to an unreasonable layout, large size, and limited number of ropes for rope embroidery, making it inconvenient to install on embroidery machine heads with limited space. Summary of the Invention

[0006] To address the problems of unreasonable structural layout, large size, multiple motors, and high cost in existing multi-specification rope embroidery devices, this invention provides a multi-specification rope embroidery device with a reasonable structural layout and fewer motors.

Detailed Implementation

[0033] See Figure 1-7 This embodiment discloses a multi-specification rope embroidery device, comprising a rope embroidery assembly 10 with at least two sets of rope embroidery mechanisms 1, a rope feeder assembly 20, a base frame 8, a first drive structure 4, a first sliding drive structure 5, a second sliding drive structure 6, and a second transmission assembly 7. Each set of rope embroidery mechanisms 1 includes a support 11, a loop head 12 mounted on the support 11, and a rope swing structure 13 for controlling and adjusting rope tension. The rope feeder assembly 20 includes rope feeders 2 corresponding to the number of sets of rope embroidery mechanisms. Each set of rope embroidery mechanisms 1 also includes a first transmission assembly, which includes a drive shaft 3. A transmission structure for driving the loop head 12 is provided between the drive shaft 3 and the loop head 12. This transmission structure is typically a drive pulley and a drive belt located between the loop head 12 and the drive shaft 3, preferably a synchronous belt, but other existing and easily implemented solutions can also be used instead.

[0034] Base frame 8 is used for positioning and installing various components; see also Figure 1-4 The base frame 8 is provided with necessary mounting parts or mounting structures for installing and connecting various components. The base frame 8 may be composed of multiple base plates connected together to connect different functional components. A lifting mechanism 81 for lifting the entire device may also be connected and installed on the base frame 8. The lifting mechanism 81 typically includes a cylinder that can be connected and installed on the external support and necessary guide rail assemblies.

[0035] The first drive structure 4 is used to drive the loop head 12 of the rope embroidery mechanism 1 into the working position. The first drive structure 4 includes a bracket 41, a third drive motor 42 mounted on the bracket 41, and a drive shaft 43 connected to the third drive motor 42. The third drive motor 42 can be mounted at a corresponding position on the bracket 41. The bracket 41 is slidably connected to the base frame 8. In this embodiment, a second pulley transmission assembly 44 is also provided between the third drive motor 42 and the drive shaft 43. The drive shaft 43 is rotatably mounted on the bracket 41. The second pulley transmission assembly 44 is preferably a synchronous pulley assembly, which typically includes a second driven pulley mounted on the drive shaft 43, a second driving pulley mounted on the third drive motor 42, and a second transmission belt.

[0036] The first sliding drive structure 5, as needed, is usually set between the base frame 8 and the rope embroidery assembly 10, and is used to drive the rope embroidery assembly 10 to slide relative to the base frame 8 so as to drive the corresponding rope embroidery mechanism 1 to slide to the working position.

[0037] The second sliding drive structure 6 is used to drive the first drive structure 4 to slide, allowing the first drive structure 4 to enter the drive position, thereby enabling the drive shaft 43 of the first drive structure 4 to engage with the transmission shaft 3 of the corresponding rope embroidery mechanism in the working position, or to disengage the first drive structure 4 from the drive position, thereby disengaging the drive shaft 43 of the first drive structure 4 from the transmission shaft 3. The second sliding drive structure 6 is typically a lifting structure that drives the first drive structure 4 to rise and fall.

[0038] The second transmission assembly 7 is used to transmit power from the drive shaft 43 to the transmission shaft 3. The second transmission assembly 7 includes an active assembly 71 disposed on the drive shaft 43 and a passive assembly 72 disposed on each transmission shaft 3. The active assembly 71 cooperates with the passive assembly 72 on the transmission shaft 3 of the rope embroidery mechanism when the first drive structure 4 enters the drive position, and disengages from the passive assembly 72 when the first drive structure 4 leaves the drive position.

[0039] The active component 71 is a drive column mounted on the drive shaft 43, and the passive component 82 is a transmission column mounted on the transmission shaft 3 of each group of rope embroidery mechanism 1. The driving column and the transmission column have mating transmission teeth between their mating surfaces.

[0040] The first sliding drive structure 5 and the second sliding drive structure 6 can adopt existing technical structures, such as hydraulic push rods, pneumatic push rods, electromagnetic push rods, linear motors, or lead screw and nut slider assemblies with a drive source. In this embodiment, the first sliding drive structure 5 includes a first drive motor 51 mounted on the base frame 8 and a first pulley transmission assembly 52. ​​The first pulley transmission assembly 52 includes a first driving pulley connected to the first drive motor 51, a first driven pulley mounted on the base frame 8, and a first transmission belt 53. The rope embroidery assembly 10 is connected to the first transmission belt 53. The second sliding drive structure 6 includes a hydraulic push rod, pneumatic push rod, electromagnetic push rod, or linear motor mounted between the bracket 41 and the base frame 8. In this embodiment, the second sliding drive structure 6 is preferably a pneumatic push rod connecting the bracket 41 and the base frame 8.

[0041] To facilitate the installation and use of the rope embroidery assembly 10, the rope embroidery assembly 10 can also be equipped with a mounting frame 9, which is used to slide and connect the base frame 8 and connect and position each rope embroidery mechanism 1. In this embodiment, the mounting frame 9 can be simplified to a long strip that connects each rope embroidery mechanism 1.

[0042] To facilitate smooth sliding drive, a first guide rail assembly 82 is provided between the base frame 8 and the rope embroidery assembly 10; the guide rail of the first guide rail assembly 82 is mounted on the frame 8, and the slider of the first guide rail assembly 82 is connected to the guide rail to install the mounting bracket 9. A second guide rail assembly 83 is provided between the bracket 41 and the base frame 8.

[0043] The rope pendulum structure 13 can adopt existing technology. The rope pendulum structure 13 includes a pendulum arm with elastic restoring force and a rope feeding hole on the pendulum arm. The elastic restoring force controls the tension of the embroidery rope 92 during rope feeding, facilitating rope embroidery. Each rope embroidery assembly 10 is equipped with a detection structure 14 to detect the rotation angle of the pendulum arm of the rope pendulum structure 13, providing rope feeding parameters to the rope feeding assembly 20. This detection structure 14 can be a Hall effect detector, which determines the tension of the embroidery rope 92 of the corresponding rope embroidery assembly 10 by detecting the swing angle of the pendulum arm of the rope pendulum structure 13. The specific swing angle of the pendulum arm being pulled by the embroidery rope during rope embroidery feeding and the relationship between the tension of the embroidery rope 92 are determined according to the actual situation.

[0044] If the detection mechanism indicates a large swing angle of the swing arm, suggesting excessive tension, this is considered a parameter for the corresponding rope feeder and is detected by the system. The system then controls the rope feeder to accelerate the rope feeding process, adjusting the rope tension to a normal level until the swing angle of the swing arm is at an appropriate range. Once this is confirmed, the rope tension is considered within the normal range, and the system controls the corresponding rope feeder to feed normally. Conversely, if the detection mechanism indicates a small swing angle of the swing arm, suggesting insufficient tension, this is considered a parameter for the corresponding rope feeder and is detected by the system. The system then controls the rope feeder to slow down or stop the rope feeding process based on the detection results, adjusting the rope tension to a normal level until the swing angle of the swing arm is at an appropriate range. Once this is confirmed, the rope tension is considered within the normal range, and the system controls the corresponding rope feeder to feed normally.

[0045] The rope feeder assembly 20 may be equipped with a linkage sliding structure that slides synchronously with the rope embroidery assembly 10, so as to minimize the impact on rope tension during the color change of the embroidery rope and facilitate stable rope feeding. The linkage sliding structure of the rope feeder assembly may be equipped with a separate guide rail assembly and a separate sliding driver, specifically designed to slide in conjunction with the rope embroidery assembly 10.

[0046] In this embodiment, preferably, each group of rope feeders 2 includes a drive wheel 21 and a clamping wheel 22 that cooperates with the drive wheel 21. The rope feeder assembly 20 is provided with a cavity for separately mounting the drive wheels 21 of each group of rope feeders 2, and a drive motor for driving the drive wheels 21 of each group of rope feeders 2. This drive motor is referred to as the second drive motor 24. The second drive motor 24 simultaneously drives the drive wheels 21 of each group of rope feeders 2, and the drive wheels of each group of rope feeders 21 can be coaxially mounted in the corresponding cavity. Each cavity is provided with a wheel frame 23 that can drive the clamping wheel 22 to cooperate and separate from the drive wheel 21. The rope feeder assembly is provided with a control structure that drives the wheel frame 23 of the corresponding rope feeder when it enters the working position so that the clamping wheel 22 cooperates with the corresponding drive wheel 21. The wheel frame 23 is provided with a return spring. Referring to the attached diagram, the upper end of the wheel frame 23 is typically rotatably mounted on the partition plate of the corresponding cavity via a return torsion spring. The torsion spring drives the wheel frame 23 to separate the clamping wheel 22 from the drive wheel 21. The control structure drives the wheel frame 23 into the working position, and the wheel frame 23 drives the clamping wheel, causing the clamping wheel in the working position to cooperate with the drive wheel to drive the embroidery rope feed located between the clamping wheel and the drive wheel. Other clamping wheels that have entered the working position are separated from the corresponding drive wheel by the return spring of the wheel frame, thus not driving the embroidery rope.

[0047] The compartment can be easily and quickly assembled into a series of rope feeders 2 via partitions, thus forming a rope feeder assembly 20. Alternatively, the compartment can be used to install the drive wheel 21 and divide the rope feeder assembly 20 into a series of rope feeders 2.

[0048] To facilitate the feeding of embroidery cord, the clamping wheel 22 and / or the drive wheel 21 are provided with cord feeding teeth; the control structure is a pressure rod 25 mounted on the base frame 8; the pressure rod 25 and the wheel frame 23 are provided with a pressure wheel, so that the pressure rod 25 can smoothly switch to drive the wheel frame 23 into the working position. The cord feeding assembly 20 is provided with a connecting plate 26 that connects the cord embroidery assembly 10 and / or the first sliding drive structure 5 to slide with the cord embroidery assembly 10. The connecting plate 26 can form a linkage sliding structure to drive the cord feeding assembly 20 to slide synchronously with the cord embroidery assembly 10. In this embodiment, the lower end of the connecting plate 26 is mounted on the mounting frame 9 of the cord embroidery assembly 10.

[0049] Each group of rope embroidery mechanisms 1 is also provided with a rope clamp 91 at the rear end, and each group of rope embroidery mechanisms 1 is provided with a first rope guide ring 15. The base frame 8 is provided with a second rope guide ring 16 corresponding to the rope embroidery mechanism 1.

[0050] Each set of rope embroidery mechanism 1 has a support 11 including a base plate 17, a vertical plate 18 disposed on the base plate 17, and a rear support 19 connecting the base plate 17 and / or the vertical plate 18. The loop head 12 is installed on the front side of the base plate 17. The rope swing structure 13 includes an elastic swing arm installed on the vertical plate 18. The transmission shaft 3 is rotatably installed on the rear support 19, and the rope clamp 91 can also be installed on the rear support 19. The first guide rope ring 15 can be disposed on the vertical plate 18.

[0051] The loop head 12 on each group of rope embroidery mechanisms 1 is arranged in front of and behind the drive shaft 3. Each group of rope embroidery mechanisms 1 is arranged sequentially on the mounting frame 9 of the rope embroidery assembly 10 along the axial direction of the swing arm provided by the rope swing structure 13. This arrangement can greatly shorten the thickness of the rope embroidery mechanism 1 and maximize the number of groups of rope embroidery mechanisms in the arrangement direction in terms of size.

[0052] The drive shaft 3 is provided with a positioning structure to position the drive shaft 3 at a specific location, so that the passive component 72 on the drive shaft 3 of the rope embroidery mechanism can quickly cooperate with the active component 71 on the drive shaft 43 when it enters the working position.

[0053] The positioning structure includes a sliding rod 33 disposed on each group of rope embroidery mechanisms, a locking assembly disposed on the sliding rod 33 and the transmission shaft 3 of the same rope embroidery mechanism 1 that can be locked and disengaged, and a transmission block 45 disposed on the bracket 41. The locking assembly includes a positioning groove 31 and a positioning block 32 disposed between the transmission shaft 3 and the sliding rod 33. The transmission block 45, as the first driving structure 4 slides and cooperates with the rope embroidery mechanism entering the working position, drives the sliding rod 33 on the rope embroidery mechanism entering the working position to slide, so that the positioning groove 31 and the positioning block 32 disengage. The sliding rod 33 is provided with an elastic body that resets the positioning groove 31 and the positioning block 32 to lock. The sliding rod 33 can be a double rod, slidably disposed in the guide hole provided in the rear support 19, and reset by a reset spring. The reset spring can be disposed on one or both sliding rods of the sliding rod 33. The positioning slot 31 can be set on the drive shaft 3, and the positioning block 32 can be set on the sliding rod 33.

[0054] The aforementioned working position is the position where the leading ring of the rope feeding mechanism can cooperate with the needle, and at the same time, the passive component 72 on the rope feeding mechanism can cooperate with the active component 71 on the drive shaft 43.

[0055] Before use, each embroidery cord of the present invention passes sequentially through the corresponding cord feeder 2, the second cord guide ring 16, the first cord guide ring 15, the cord feed hole and the head ring 13 on the swing arm of the corresponding cord embroidery mechanism 1 of the cord embroidery assembly 20, and finally the cord end is clamped by the corresponding cord clamp 91. After each embroidery cord is threaded, it is ready for cord embroidery. Before use, the pneumatic push rod (i.e., cylinder) of the second sliding drive structure 6, which is raised and lowered by default, can be lifted by the drive shaft 43 of the bracket 41, so that the active component 71 on the drive shaft 43 is disengaged from the position that can cooperate with the passive component 72.

[0056] When the rope embroidery device of the present invention is in use, according to the rope embroidery process, the first drive motor 51 of the first sliding drive structure 5 drives the rope embroidery assembly 10—the rope embroidery mechanism 1—to enter the working position through the first pulley transmission assembly 52. ​​The pneumatic push rod (i.e., cylinder) of the second sliding drive structure 6 drives the drive shaft 43 to move down to the driving position through the bracket 41, so that the active component 71 and the passive component 72 of the second transmission assembly 7 can cooperate, thereby driving the transmission shaft 3. The transmission block 45, which moves down with the bracket 41, simultaneously drives the sliding rod 33 of the rope embroidery mechanism 1, which has entered the working position, so that the positioning block 32 on the sliding rod 33 disengages from the positioning slot 31 on the transmission shaft 3. The third drive motor 42 is started, and the third drive motor 42 drives the drive shaft 43 to rotate through the second pulley transmission assembly 44, and then drives the transmission shaft 3 through the second transmission assembly 7. The transmission shaft 3 drives the loop head 12 through the first transmission assembly to generate the torsional action required for rope embroidery.

[0057] After the rope of the rope embroidery mechanism 1 is finished, the pneumatic push rod (i.e., cylinder) of the second sliding drive structure 6, which is raised and lowered by the first drive structure 4, drives the bracket 41 and drive shaft 43 to be lifted. This causes the active component 71 on the drive shaft 43 to disengage from the position that engages with the passive component 72 of the transmission shaft of the rope embroidery mechanism. The transmission block 45, which moves upward with the support 41, disengages from the sliding rod 33 of the rope embroidery mechanism. Under the action of the return spring, the sliding rod 33 of the rope embroidery mechanism slides upward, causing the positioning block 32 on the sliding rod 33 to lock with the positioning slot 31 on the transmission shaft 3. This ensures that the transmission teeth on the passive component 72 on the transmission shaft are positioned in a position that can engage with the active component 71, ready for the next rope embroidery.

[0058] When it is necessary to continue rope embroidery, according to the rope embroidery process, the first drive motor 51 of the first sliding drive structure 5 drives the other corresponding rope embroidery mechanism 1 of the rope embroidery assembly 10 to enter the working position through the first pulley transmission assembly 52. ​​The workflow can refer to the above process.
