Description

Technical Field

[0001] The present invention relates to the technical field of computer embroidery machines, and in particular to a multi-color rope / ribbon embroidery device with a tracking function. Background Art

[0002] The cord embroidery process is a relatively new process currently used on computer embroidery machines. The process is roughly as follows: the multi-color cord / ribbon embroidery device on the machine head drives the cord / ribbon to move horizontally onto the embroidery cloth, and the flat embroidery device on the machine head drives the embroidery thread to move horizontally to embroider the cord / ribbon on the embroidery cloth.

[0003] On a computerized embroidery machine, the machine head is located at the top, and the embroidery frame, which holds the embroidery fabric, is located below. The embroidery frame typically moves horizontally according to the design, causing the fabric to move horizontally relative to the machine head. In multi-color cord embroidery, the multi-color cord / ribbon embroidery device must drive multiple cords / ribbons to change colors horizontally, moving the cords / ribbons of a specific color / style below the specific color embroidery thread on the flat embroidery device. This frequent relative movement can easily cause deviations between the cords / ribbons and the fabric, or even deformation. This can lead to missing cords / ribbons and leaving some cords / ribbons unattached to the fabric, directly impacting the quality of the embroidery. Consequently, current cord embroidery production is limited by process technology, making it difficult to automate the simultaneous embroidery of multiple-color cords / ribbons and, consequently, unable to produce high-quality embroidery with certain patterns.

[0037] like Figure 1-2 As shown, a multi-color rope / ribbon embroidery method with a tracking function is applied to a computer embroidery machine. The computer embroidery machine is provided with a machine head, and a multi-color rope / ribbon embroidery device 100 and a flat embroidery device 200 are provided on the machine head. The multi-color rope / ribbon embroidery device 100 is equipped with two or more ropes / ribbons 1, and the flat embroidery device 200 is equipped with a plurality of embroidery threads 2, embroidery needles 3, and a presser foot 4. The multi-color rope / ribbon embroidery method with a tracking function includes the following steps:

[0038] S1: The multi-color rope / ribbon embroidery device 100 is provided with two or more rotating traction members 5, and each rope / ribbon passes through a traction member 5 and can rotate synchronously therewith;

[0039] S2: The embroidery needle 3 on the flat embroidery device 200 drives the embroidery thread 2 to move up and down, and embroiders the rope / belt 1 on the embroidery cloth.

[0040] In some application embodiments of the present invention, S1 also includes S11: a guide nozzle 6 is synchronously installed in each traction member 5, and a rope hole groove 601 is provided on the guide nozzle 6. After the rope / belt 1 passes through the rope hole groove 601, it rotates synchronously with the traction member 5.

[0041] During production, whether to use the guide nozzle 6 can be selected according to the material and style of the rope / belt 1. The rope / belt 1 can also be straightened by replacing different guide nozzles 6 and providing rope and belt hole grooves 601 with different outline sizes on different guide nozzles 6 to avoid deformation or knotting during rotation. By replacing different guide nozzles, the needs of automated and efficient production of high-quality embroidery products with different techniques such as rope embroidery, belt embroidery, dark embroidery, feather embroidery, and Z-shaped embroidery can be met, and the scope of application is relatively wide.

[0042] The application examples of the present invention are as follows:

[0043] Figure 2 The specific implementation structure of this embodiment on a computer embroidery machine is shown. The multi-color rope / ribbon embroidery device 100 is a multi-color rope / ribbon embroidery device with a tracking function. The multi-color rope / ribbon embroidery device applies the above-mentioned multi-color rope / ribbon embroidery method. The multi-color rope / ribbon embroidery device with a tracking function is provided with a translation mechanism 20, a traction tracking mechanism 30 and a color changing mechanism 40.

[0044] like Figure 3 As shown, the translation mechanism 20 includes a mounting plate 21, on which a first driving device 22 is provided. The first driving device 22 is in transmission connection with a first slide 24 and can drive the first slide 24 to move in the Z direction; a second mounting frame 25 is provided on the first slide 24, and a second guide rail 26 is provided on the second mounting frame 25, which is horizontally arranged and laterally extending. A second slide 27 is provided on the second guide rail 26, and the second slide 27 is in transmission connection with a second driving device 29 via a second transmission device 28 and can slide on the second guide rail 26 under the drive of the second transmission device 28;

[0045] like Figure 3-4As shown, the traction tracking mechanism 30 is arranged on the second slide 27, and the second slide 27 is provided with a third plate 31 and a fourth plate 32 that are detachably fixed: the third plate 31 is provided with a third guide rail 33 that is horizontally arranged and extends laterally, and the longitudinal end face of the third guide rail 33 away from the third plate is a continuous wavy surface; the fourth plate 32 is arranged horizontally, and one end portion thereof extending laterally is arranged with more than one traction member 5 at equal intervals along a straight line, and each traction member 5 is provided with a rope / belt 1, and each traction member 5 is connected to the third drive device 35 through a third transmission device 34, and each third drive device 35 can drive a traction member 5 to rotate on the fourth plate 32 and can synchronously pull a rope / belt 1 to move relative to the fourth plate 32; each traction member 5 is an annular structure and is installed on the fourth plate 32 through a bearing, and the outer wall of each traction member 5 is provided with a first hole groove 501 that is adapted to the rope / belt 1. In some application embodiments of the present invention, the second transmission device 28 includes a first synchronous belt 282 horizontally mounted on the second mounting frame 25 via a pulley 281 and extending in the transverse direction. The second slide plate 27 is detachably fixed to the first synchronous belt 282 .

[0046] like Figure 5 As shown, in some application embodiments of the present invention, a reset member 44 is further provided on the third mounting frame 41, and the reset member 44 includes a plurality of third guide rods 45 horizontally arranged on the third mounting frame 41 and extending longitudinally, a transverse arm 421 passes through each third guide rod 45 and can slide along the same, and an elastic member 46 can be sleeved on each third guide rod 45 between the transverse arm 421 and the third mounting frame 41.

[0047] like Figure 5-6As shown, the color-changing mechanism 40 includes a third mounting frame 41 provided on the second mounting frame 25, an L-shaped fifth plate 42 being slidably mounted on the third mounting frame 41, a third driving device 35 being provided on a transverse arm 421 of the fifth plate 42, and a fifth transmission member 43 being provided on a longitudinal arm 422 of the fifth plate 42. The fifth transmission member 43 abuts against the wavy end surface of the third guide rail 33 and can longitudinally move away from or toward the third plate 31 when it translates laterally, and drive the third driving device 35 thereon to move synchronously to disconnect or connect the transmission connection with the third transmission device 34. In some application embodiments of the present invention, the third transmission device 34 includes a plurality of first pulley shafts 341, a plurality of second pulley shafts 342, a plurality of second synchronous belts 343 and a fourth gear 344: the plurality of first pulley shafts 341 and the plurality of second pulley shafts 342 are respectively arranged at equal intervals along a straight line at the two transversely extending ends of the fourth plate 32, each first pulley shaft 341 is axially arranged with a first pulley 7 and a traction member 5, each second pulley shaft 342 is axially arranged with a second pulley 8 and a third gear 9, and each second pulley 8 and a first pulley 7 are provided with a second synchronous belt 343; the fourth gear 344 is connected to the third driving device 35 in transmission and can rotate under its drive, and the fourth gear 344 is horizontally arranged beside the plurality of third gears 9 and can be meshed with any third gear 9. Figure 7 As shown, in this embodiment, a horizontally arranged and extended switch shaft 36 is further provided on the third plate 31 below the third guide rail 33, and a number of torsion springs 37 are installed at equal intervals on the switch shaft 36, one end of each torsion spring 37 abuts against the third plate 31, and the other end can abut against the upper end face of a third gear 9; the upper end face of each third gear 9 is provided with a card slot 901 adapted to a torsion spring 37; each first pulley shaft 341 is a hollow shaft, and is integrally formed with a traction member 5, and the lower end of each first pulley shaft 341 is provided with a first hole groove 501.

[0048] It can be understood that each torsion spring 37 on the switch shaft 36 can be matched and clamped in the slot 901 of a third gear 9 to lock each third gear 9; when a third gear 9 is synchronously translated with the third plate 31 to engage with the fourth gear 344, the third drive device 35 will drive the third gear 9 to rotate and disengage the lock of the torsion spring 37, so as to smoothly carry out the traction tracking of the rope / belt.

[0049] In this embodiment, the first drive device 22, the second drive device 29, and the third drive device 35 are all circular motion drive devices. The first drive device 22 is connected to the first slide 24 through a screw-nut transmission pair; the fifth transmission member 43 is a roller mounted on the longitudinal arm 422 and rotatable relative to it. Its smooth surface can reduce the friction with the wavy end surface on the third guide rail 33, ensuring that the two can perform smooth and frequent relative motion, thereby ensuring smooth color change of the rope.

[0050] like Figure 8-9 As shown, in some application embodiments of the present invention, an annular guide nozzle 6 can be detachably fixed on the inner wall of each traction member 5, and each guide nozzle 6 has one or more rope hole grooves 601 adapted to the rope / belt 1 on the side wall.

[0051] It is understandable that the provision of the guide nozzle 6 can prevent the rope / belt 1 from being twisted or tangled due to the rotation of the traction member 5 . Figure 8 This is the guide nozzle 6 used in the rope embroidery in this embodiment, and the rope hole slot 601 on it is a round hole adapted to the rope contour. Figure 9 The guide mouth 6 is used in ribbon embroidery and feather embroidery in this embodiment. The rope hole slot 601 thereon is a flat slot adapted to the rope and feather, which can straighten the rope during its rotation and pulling process to avoid it from getting knotted or deformed.

[0052] In some application embodiments of the present invention, the mounting plate 21 is hinged to the machine head or the computer embroidery machine.

[0053] It is understandable that the hinged structure is set to facilitate adjustment of the angles of the multi-color rope / ribbon embroidery device 100 and the flat embroidery device 200 before production, and the two can be pulled apart in the shutdown state to adjust them separately.

[0054] Before operation, the required multiple embroidery threads 2 of different colors are first installed on the flat embroidery device 200. The required multiple ropes / belts 1 of different colors / styles are pulled down from the thread rack and passed through a traction member 5 one by one. The other end is fixed to the embroidery machine. The mounting plate 21 is rotated, and the first drive device 22 drives 30, the traction tracking mechanism 30, and the color changing mechanism 40 to move in the Z direction, bringing the fourth plate 32 and the traction member 5 thereon to an appropriate angle and position relative to the presser foot 4. During operation, the third drive device 35 drives the fourth gear 344 to rotate. The fourth gear 344 meshes with a third gear 9, driving the second pulley shaft 342 to rotate. The second pulley 8 on the fourth gear shaft drives the first pulley 7 via the second synchronous belt 343, which in turn drives the first pulley shaft 341 / traction member 5 and the guide nozzle 6 therein to rotate, thereby pulling the rope / belt to cause angular deflection. When the rope needs to be replaced, the second driving device 29 drives the second slide 27 to translate, and the third plate 31 on the second slide 27 drives the third guide rail 33 to translate synchronously. The wave crest of its wavy end face pushes the fifth transmission member 43 to move away from the third plate 31, driving the fifth plate 42 and the third driving device 35 thereon to move synchronously, driving the fourth gear 344 to move so that it disengages from the third gear 9, and the first slide 21 translates the other third gear 9 to the front of the fourth gear 344. At the same time, the fifth transmission member 43 falls into the trough of the end face of the third guide rail 33, driving the third driving device 35 and the fourth gear 344 to synchronously approach the third plate 31, and the fourth gear 344 is meshed and connected with the third gear 9 to complete the color changing action.

[0055] The present invention rotates the traction member 5 of the traction rope / belt 1 on the multi-color rope / belt embroidery device 100, thereby realizing the rotation of the rope / belt 1 within a certain range during embroidery production, so that it can always closely follow the movement of the moving embroidery frame and embroidery cloth, ensuring that the embroidery thread 2 on the flat embroidery device 200 can completely fix its embroidery on the embroidery cloth, avoiding the phenomenon of missing ties during the embroidery process; by arranging a guide mouth 6 in the traction member 5, the deformation or knotting of the rope / belt 1 during the rotation process can be avoided, thereby improving the quality of the embroidery; by arranging the translation mechanism 20 and the color changing mechanism 40, automatic switching of ropes / belts 1 of different colors / styles during production can be realized with high efficiency. By replacing different guide mouths 6, the needs of automated production of high-quality complex embroidery products with different techniques such as rope embroidery, belt embroidery, dark embroidery, feather embroidery, and Z-shaped embroidery can be met, and the scope of application is relatively wide.

[0056] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
