Abstract
Description
Technical Field
[0001] This invention relates to a method for using a ribbon embroidery machine head and ribbon. Background Technology
[0002] Existing ribbon embroidery passively feeds the ribbon from the feed nozzle via a material rack. The ribbon is fixed to the fabric by the needle. As the ribbon is continuously embroidered, the fabric is continuously dragged by the corresponding rollers of the embroidery frame or quilting, constantly "pulling" the ribbon from the feed nozzle. This pulling force directly and passively feeds the ribbon from the material wheel. When embroidering large ribbons, the size of the ribbon itself and the amount of ribbon on the reel can all cause uneven ribbon feeding and unstable ribbon tension. If the ribbon tension is too high when the needle is down, the ribbon at the point of embroidery will be suspended in mid-air, resulting in inaccurate needle insertion. After the needle is down, the sewing thread cannot tighten the ribbon, leading to deformed and unsightly ribbon embroidery or even making effective ribbon embroidery impossible. Summary of the Invention
[0003] To address the problems that may arise during the embroidery process of existing ribbon embroidery, such as poor ribbon feeding and loss of ribbon tension during needle insertion, this invention provides a ribbon embroidery machine head and a method for facilitating ribbon feeding and stabilizing ribbon tension during ribbon embroidery.

The drive arm cooperates with the presser foot and / or the presser foot lifting sleeve to transmit power and drive the second lifting belt rod to move; or the drive arm cooperates with the corresponding transmission structure connected to the presser foot and / or the presser foot lifting sleeve to drive the second lifting belt rod to move.
[0007] As a further improvement, the conveyor belt assembly also includes a fixed frame connected to the material rack or the outer shaft of the multi-functional shaft, a drive arm with its fulcrum located on the fixed frame to form a lever, and the conveyor belt rod being set on the resistance arm of the drive arm. The drive arm cooperates with the presser foot and / or the presser foot lifting sleeve to transmit power and drive the conveyor belt rod to move; or the drive arm cooperates with the corresponding transmission structure connected to the presser foot and / or the presser foot lifting sleeve to drive the conveyor belt rod to move.
[0008] As a further improvement, the resistance arm of the drive arm is larger than the power arm, and the second lifting rod is disposed on the resistance arm.
[0009] As a further improvement, the power arm of the drive arm is provided with a transmission arm that cooperates with the connecting frame provided on the presser foot and / or the presser foot lifting sleeve to transmit the power of the connecting frame.
[0010] As a further improvement, a belt guide frame is also included, wherein the guide frame is provided with at least one guide shaft and / or guide wheel for the belt, and the guide frame is mounted on the outer shaft of the material rack and / or the multi-functional shaft.
[0011] As a further improvement, the mounting bracket is provided with at least one belt guide shaft and / or guide wheel.
[0012] As a further improvement, the conveyor belt is equipped with a roller, or the conveyor belt is rotatably configured.
[0013] As a further improvement, the second conveyor belt is provided with a roller, or the second conveyor belt is rotatably mounted on the drive arm.
[0014] As a further improvement, the presser foot is provided with a guide head on the input side of the tape. The guide head includes a guide end on the input side of the tape, a first guide surface on one side of the tape input path, and a second guide surface on the other side of the tape input path. The first guide surface, the second guide surface, and the guide end together form the guide head.
[0015] As a further improvement, the first guide surface and / or the second guide surface gradually slope inward from the point of contact with the pressure foot to the guide end; the guide heads are symmetrically arranged, and the axis of symmetry of the guide heads is the axis of the pressure foot.
[0016] As a further improvement, the presser foot is provided with a guide nipple for guiding the belt input, and the belt picking rod is located on the input side of the guide nipple.
[0017] This invention also discloses a method for embroidering ribbon using any combination of the above-mentioned schemes on a ribbon embroidery machine head. The conveyed ribbon is fed around the ribbon picker rod of the ribbon picker assembly and then input into the ribbon position. During ribbon embroidery, when the presser foot moves upward, the ribbon picker rod of the ribbon picker assembly moves with the presser foot lifting sleeve or / and the presser foot rising, picking and pulling the ribbon. When the presser foot moves downward, the ribbon picker rod returns with the presser foot moving downward, and the ribbon picked up by the ribbon picker rod becomes loose. The needle then embroiders the loose ribbon onto the embroidery cloth, completing one stitch of ribbon embroidery, and then continues the above ribbon embroidery process. During the ribbon embroidery process, after the ribbon is fixed to the embroidery cloth by at least one stitch, the ribbon picker rod of the ribbon picker assembly moves with the presser foot lifting sleeve or / and the presser foot rising, picking and pulling the ribbon. The ribbon at the input position is pulled, and as the ribbon picker rod moves downward, the ribbon becomes loose.
[0018] As a further improvement, the conveyed belt is sequentially routed around the second pick-up rod of the second pick-up assembly and the pick-up rod of the pick-up assembly before being fed into the embroidery belt position. During embroidery, as the presser foot moves upward, the pick-up rod of the pick-up assembly and the second pick-up rod of the second pick-up assembly are moved and pulled along with the presser foot lifting sleeve and / or the presser foot rising.
[0019] As a further improvement, the conveyed belt is sequentially routed around the guide shaft and / or guide wheel of the guide frame, and the belt picking rod of the belt picking assembly before being fed into the embroidery belt position.
[0020] As a further improvement, the conveyed belt is sequentially routed around the guide shaft and / or guide wheel of the fixed frame, the second pick-up rod of the second pick-up assembly, and the pick-up rod of the pick-up assembly before being fed into the embroidery belt position.
[0021] As a further improvement, the conveyed belt is routed around the picking rod of the picking assembly and then fed into the embroidery belt position via the guide nozzle.
[0022] Compared with existing technologies, the present invention provides a tape-picking assembly for the tape embroidery machine head and tape method. This assembly includes a tape-picking rod that moves with the lifting action of the presser foot or presser foot lifting sleeve to pick up the tape. The tape-picking rod is positioned on the tape input side. The conveyed tape is fed into the tape position after passing through the tape-picking rod of the assembly. During tape embroidery, as the presser foot moves upward, the tape-picking rod of the assembly moves with the presser foot lifting sleeve and / or the presser foot itself to pick up and pull the tape. As the presser foot moves down, the ribbon pick-up bar returns, loosening the ribbon that was picked up by the pick-up bar. The needle then stitches the loosened ribbon onto the embroidery cloth, completing one stitch of ribbon embroidery. This process continues. During ribbon embroidery, after the ribbon is secured to the embroidery cloth by at least one stitch, the pick-up bar of the ribbon pick-up assembly pulls the ribbon as the presser foot rises or / and the presser foot rises. The ribbon is pulled from the input point, and as the pick-up bar moves down, the ribbon loosens, fulfilling the needs of ribbon embroidery.
[0023] Its beneficial effect is that it utilizes the normal reciprocating motion of the presser foot during ribbon embroidery, and drives the reciprocating movement of the ribbon take-up lever through the presser foot or presser foot lifting sleeve. During the upward movement of the presser foot, the take-up lever picks up the input ribbon. Except for the first stitch, the ribbon is not fixed to the embroidery cloth. In subsequent ribbon embroidery processes, because the ribbon is fixed to the embroidery cloth by the stitches, the upward-moving take-up lever can only pull the ribbon out from the ribbon input point. Since the take-up lever forms a movable pulley, the pulled-out ribbon is usually twice the distance the take-up lever has traveled. As the presser foot moves downward, the downward-moving take-up lever loosens the picked-up ribbon, and the loosened ribbon is easier for the downward-moving needle to embroider onto the embroidery cloth.

[0035] Figure 14 This is a front view of a preferred implementation case of the conveyor nozzle of a tape embroidery machine. Detailed Implementation
[0036] See Figure 1-14 A ribbon embroidery machine head includes a machine head body, a multi-functional shaft 5 and a corresponding drive structure for the multi-functional shaft 5, wherein the multi-functional shaft 5 has a presser foot 3 on the presser foot lifting sleeve 31, and also includes a ribbon picking assembly 1, wherein the ribbon picking assembly 1 includes a ribbon picking rod 11 that moves with the presser foot 3 or the presser foot lifting sleeve 31, and the ribbon picking rod 11 is located on the input side of the ribbon 6.
[0037] Implementation Case 1, see Figure 1-3 The carrying rod 11 can be connected to the presser foot 3 and / or the presser foot lifting sleeve 31 via the connecting bracket 12. That is, the carrying rod 11 of the carrying assembly 1 can be connected to the presser foot 31 or the presser foot lifting sleeve 31 via the connecting bracket 12, or simultaneously connected to both the presser foot and the presser foot lifting sleeve. In this embodiment, in order to facilitate the replacement of the presser foot 3, the carrying rod 11 of the carrying assembly 1 is connected to the presser foot lifting sleeve 31 via the connecting bracket 12, so that the replacement of the presser foot can avoid affecting the carrying assembly 1.
[0038] As a preferred embodiment of this case, in order to smoothly move the belt, a belt 6 guide frame 4 is also included. The guide frame 4 is provided with at least one guide shaft and / or guide wheel 41 for the belt 6. The guide frame 4 can be installed on the outer shaft of the material rack 51 and / or the multi-functional shaft 5. The guide frame 4 can be directly or indirectly installed on the outer shaft of the material rack 51 and / or the multi-functional shaft 5 through an intermediate connecting structure.
[0039] The belt-picking rod 11 is equipped with a roller, or the belt-picking rod 11 can be rotatably mounted on the connecting frame 12. The presser foot 3, presser foot lifting sleeve 31, multi-functional shaft 5, and their corresponding drive structure can adopt existing publicly available technical structures. The multi-functional shaft 5 is usually equipped with a material rack 51, and the material rack 51 is equipped with a belt feeding wheel 7. Of course, the belt can also be fed from an external belt source to the corresponding position of the presser foot after being guided. The multi-functional shaft 5 can also be equipped with a rope pendulum and transmission components, etc. In this embodiment, when embroidering with belt, the input belt 6 can be wound around the belt-picking rod 11. The belt-picking rod picks up the belt as the presser foot 3 rises, so that the belt is pulled out from the output feeding wheel, thereby loosening the belt. This makes it easier to fix the belt to the embroidery cloth through the stitch when the needle goes down to embroider the belt, thereby effectively avoiding the problem that the needle cannot fix the belt through the stitch due to excessive belt tension. As the belt-picking rod 11 moves upward to pick up and pull the belt, the belt-picking rod 11 can act as a movable pulley. The length of the belt pulled from the feed wheel 7 by the belt-picking rod 11 is twice the distance that the belt-picking rod 11 moves with the presser foot.
[0040] Implementation Case 2, see Figure 4-9When the length of the tape pulled by a single picking rod 11 is insufficient to meet the needs of tape embroidery, a second picking assembly 2 is added based on implementation case 1 to further increase the tape output. The second picking assembly 2 includes a fixed frame 22 connected to the material rack 51 or the outer shaft of the multi-functional shaft 5, a drive arm 23 with its fulcrum located on the fixed frame 22 forming a lever, and a second picking rod 21 mounted on the resistance arm of the drive arm 23. The drive arm 23 cooperates with the presser foot 3 and / or the presser foot lifting sleeve 31 to transmit power and drive the second picking rod 21; or the drive arm 23 cooperates with the corresponding transmission structure connected to the presser foot 3 and / or the presser foot lifting sleeve 31 to drive the second picking rod 21. The second picking rod 21, combined with the first picking rod 11, simultaneously picks the tape, increasing the amount of tape pulled from the feed wheel 7.
[0041] The second lifting rod 21 is provided with a roller, or the second lifting rod 21 is rotatably mounted on the drive arm 23.
[0042] Since both the first and second pick-up rods 11 and 21 act as pulleys, the length of tape pulled from the feed wheel 7 by the movement of the first and second pick-up rods 11 and 21 is many times the distance that the first and second pick-up rods 11 and 21 move with the presser foot 3. This effectively meets the tape requirements of embroidery.
[0043] In Implementation Example 3 (without a clearly defined drawing), the conveyor belt assembly further includes a fixed frame connected to the material rack or the outer shaft of the multi-functional shaft, and a drive arm with its fulcrum located on the fixed frame to form a lever. The conveyor belt rod is mounted on the resistance arm of the drive arm. The drive arm cooperates with the presser foot and / or the presser foot lifting sleeve to transmit power and drive the conveyor belt rod to move; or the drive arm cooperates with the corresponding transmission structure connected to the presser foot and / or the presser foot lifting sleeve to drive the conveyor belt rod to move. In this implementation example, the structure of the fixed frame and the drive arm is the same as that in Implementation Example 2. The conveyor belt rod on the drive arm is the same as the second conveyor belt rod 21 in Implementation Example 2, except that the conveyor belt rod 11 on the connecting frame 12 in Implementation Example 1 is removed. In this implementation example, the connecting frame can be configured differently from that in Implementation Example 1, and is only used to drive the drive arm to move, so that the conveyor belt rod on the drive arm moves with the presser foot or the presser foot lifting sleeve to move and pick up the conveyor belt. Of course, in order to make the belt picker lever pick the belt smoothly in this implementation case, the shape of the drive arm and the belt winding path can be appropriately changed to make it easier for the drive arm to pick the belt when it moves. For example, the height of the input side of the belt that winds around the picker lever can be increased by the guide shaft and / or guide wheel on the fixed frame, and the drive arm can be set as a curved arm so that when the drive arm moves, the picker lever on the drive arm can move up and down more smoothly to pick the belt.
[0044] In this implementation, the moving guide rod pulls the tape, acting as a movable pulley. The length of tape pulled from the feed wheel 7 by the guide rod is many times the distance the guide rod 21 moves with the presser foot 3. This effectively meets the tape requirements of the embroidery.
[0045] As a further preferred embodiment, in embodiments 2 and 3, the resistance arm of the drive arm 23 is larger than the power arm. In embodiment 2, the second lifting rod 21 is mounted on the resistance arm, and in embodiment 3, the lifting rod is mounted on the resistance arm. This makes the drive arm 23 a lever that requires less effort, thereby further increasing the pulling amount of the belt.
[0046] In Implementation Example 2, the drive arm 23 of the second conveyor belt assembly 2, and in Implementation Example 3, can be driven directly or indirectly by the presser foot, directly or indirectly by the presser foot lifting sleeve, or directly or indirectly by the combination of the presser foot and the presser foot lifting sleeve. Preferably, the drive arm 23 is driven by the connecting frame 12. The corresponding power arm of the drive arm 23 is provided with a transmission arm 24 that cooperates with the connecting frame 12 and transmits power to the connecting frame 12. See Appendix. Figure 4-9 The transmission arm 24 is designed as a curved arm to facilitate cooperation with the connecting frame 12.
[0047] In order to move the belt more smoothly, the fixing frame 22 described in Examples 2 and 3 is provided with at least one belt guide shaft and / or guide wheel 41.
[0048] In Implementation Case 4, since the belt-carrying rod assembly is installed, it can also serve as a belt guide, thus eliminating the need for a guide nozzle. This could be achieved by using a guide shaft and / or guide wheel 41 on the belt-carrying rod assembly, or by installing a stop ring on the belt-carrying rod to limit belt deviation. A similar structure can also be used for the second belt-carrying rod assembly.
[0049] As a preferred embodiment, based on embodiments 1, 2 or 3, the presser foot 3 is provided with a guide nipple 30 for the input of the guide tape 6, and the pick-up rod 11 is set on the input side of the guide nipple 30. The tape can be finally transported from the guide nipple 30 to the embroidery tape position after passing through the corresponding pick-up rod. The embroidery tape position is directly below the needle, and the tape can be embroidered onto the embroidery cloth by the needle.
[0050] Implementation Case 5, see Figure 10-14 Based on implementation cases 1, 2, 3 or 4, the presser foot 3 is provided with a guide head 32 on the input side of the tape 6. The guide head 32 includes a guide end 33 on the input side of the tape, a first guide surface 34 on one side of the tape input path, and a second guide surface 35 on the other side of the tape input path. The first guide surface 34, the second guide surface 35 and the guide end 33 form the guide head 32.
[0051] The first guide surface 34 and / or the second guide surface 35 gradually slope inward from the point of contact with the pressure foot 3 to the guide end 33; the guide heads 32 are symmetrically arranged, and the axis of symmetry of the guide heads 32 is the axis of the pressure foot 3.
[0052] During continuous ribbon embroidery, the ribbon is fixed to the fabric by the top thread and / or the bottom thread. After the ribbon is stitched with the top thread, the ribbon fixed to the fabric will fold upwards on one or both sides of the stitch, forming a folded "lace" that creates a three-dimensional pattern. During continuous embroidery, as the guide head 32 moves relative to the fabric, the guide end 33, the first guide surface 34, and / or the second guide surface 35 can touch the ribbon stitches formed by the previous embroidery before the presser foot itself, effectively pushing the lace of the previous ribbon stitches outwards. This effectively prevents subsequent embroidery from pressing down on the lace of the already completed ribbon stitches when they are close to the previous stitches, and avoids the needle sewing on the lace of the previous ribbon stitches. This structure is simple, and the resulting ribbon pattern is quite perfect.
[0053] The present invention also discloses a method for embroidering ribbons using any combination of the above-mentioned schemes on a ribbon embroidery machine head.
[0054] Case study 1 of the implementation of the ribbon embroidery method, see [link / reference]. Figure 1-3 The tape 6 conveyed on the material rack 51 is fed into the embroidery tape position after passing through the tape picking rod 11 of the tape picking assembly 1; during the tape embroidery process, when the tape embroidery machine head drives the presser foot 3 to move upward, the tape picking rod 11 of the tape picking assembly 1 moves with the presser foot 3 lifting sleeve or / and the presser foot 3 rising. Figure 1-3 It moves upwards, and the specific direction of movement depends on the path of the belt winding, so as to facilitate picking up the belt. The belt 6 is picked up and pulled; as the presser foot 3 moves downwards, the belt-picking rod 11 moves back with the presser foot 3. Figure 1-3 (When the needle moves downwards), the ribbon 6, lifted by the lifting rod 11, becomes slack, and the needle embroiders the slack ribbon 6 onto the embroidery cloth, completing one stitch of ribbon embroidery. This process is then continued. When the needle moves downwards to embroider the ribbon, the slack ribbon 6 effectively ensures that the needle can accurately embroider the ribbon.
[0055] During the ribbon embroidery process, before the ribbon is fixed to the embroidery cloth by the needle stitch, the ribbon picker 11 picks up the ribbon as the presser foot 3 moves upward. The ribbon picker 11 will pull the ribbon on both sides, making the ribbon loose. Therefore, before the first stitch is made by the needle, the ribbon end needs to be pulled a longer distance from the embroidery ribbon position so that when the ribbon picker 11 pulls it for the first time, there is still an appropriate ribbon in the embroidery ribbon position.
[0056] After the tape 6 is fixed to the embroidery cloth by at least one stitch, the tape take-up lever 11 of the tape take-up assembly 1 pulls the tape 6 as the presser foot 3 rises or / and the presser foot 3 rises. Since the tape head is fixed to the embroidery cloth by the stitch, only the tape 6 located on the input side can be pulled. After the tape is pulled, the tape 6 is relaxed as the tape take-up lever 11 moves down.
[0057] As a preferred embodiment, the conveyed belt 6 can first pass around the guide shaft and / or guide wheel 41 of the guide frame 4, and then pass around the pick-up rod 11 of the pick-up assembly 1 before being fed into the embroidery belt position.
[0058] As a further preferred option, the conveyed belt 6 is wound around the picking rod 11 of the picking assembly 1 and then fed into the embroidery belt position through the guide nozzle 30.
[0059] Case study 2 of the implementation of the ribbon embroidery method, see [link / reference]. Figure 4-9 The conveyed belt 6 is sequentially routed around the second pick rod 21 of the second pick rod assembly 2 and the pick rod 11 of the pick rod assembly 1 before being fed into the embroidery belt position.
[0060] During the embroidery process, when the presser foot 3 moves upward, the working principle of the belt-picking rod 11 of the belt-picking assembly 1 is the same as in Implementation Case 1 of the embroidery method. As the presser foot 3 moves upward, the connecting frame 12 connected to the presser foot lifting sleeve 31 drives the drive arm 23 to rotate around the fixed frame 22 via the transmission arm 24. This causes the second belt-picking rod 21 on the resistance arm of the drive arm 23 to move and pick up the belt that passes over the second belt-picking rod 21. The second belt-picking rod 21, in conjunction with the belt-picking rod 11, picks up the belt simultaneously, which can further increase the amount of belt picking and the amount of belt pulled from the feed wheel 7. Preferably, the drive arm 23 is a force-multiplying lever, which can further increase the amount of belt picking.
[0061] As presser foot 3 moves downward, the ribbon pick 11 moves with presser foot 3, and the ribbon 6 picked up by the ribbon pick 11 and the second ribbon pick 21 becomes loose. The machine needle stitches the loose ribbon 6 onto the embroidery cloth, completing one stitch of ribbon embroidery, and then continues the above ribbon embroidery process.
[0062] As a preferred embodiment, the conveyed belt 6 is sequentially routed around the guide shaft and / or guide wheel 41 of the fixed frame 22, the second pick-up rod 21 of the second pick-up assembly 2, and the pick-up rod 11 of the pick-up assembly 1 before being fed into the embroidery belt position.
[0063] As a further preferred option, the conveyed belt 6 is wound around the picking rod 11 of the picking assembly 1 and then fed into the embroidery belt position through the guide nozzle 30.
[0064] In the above implementation examples, the belt-picking rod and the second belt-picking rod can be of various shapes, but they are usually set as round rods that are easy to pick up the belt.
