Description

Technical Field

[0001] One or more embodiments of the present disclosure relate to the technical field of embroidery machines, and in particular, to a tape embroidery device, an embroidery machine, and a tape embroidery feeding control method. Background Art

[0002] The tape embroidery device is used to embroider ribbons and / or ropes and other ribbon-like objects. The tape embroidery device is generally composed of a housing, a driving spindle, a needle rod, a feeder, a presser foot, and a thread take-up rod. In order to increase the continuous working time of the tape embroidery, the existing feeder uses a large-sized material tray to carry a large capacity of tape. During the tape embroidery operation, the machine needle inserts into the embroidery material, and the surface thread locks the rope or belt on the embroidery material. At this time, the embroidery frame is moved, and the embroidery frame will drive the rope / belt to move. When the size of the material tray increases, the rope or belt will be mechanically pulled out of the material tray, and there is a large pulling force between the embroidery frame and the material tray, which will deform the embroidery and cause poor embroidery. If a feeding motor is set on the material tray, the feeding motor is used to drive the material tray to actively feed the material to cooperate with the movement of the embroidery frame.

[0003] In some related technologies, a rope-retracting and -releasing mechanism and a tensioning mechanism are installed on the tape embroidery device to cooperate with each other to adjust the rope tension and realize automatic rope-retracting and -releasing. However, the above structure is relatively complex and occupies installation space, and it is impossible to install a large number of tape embroidery devices on the embroidery machine. In addition, the rope is output from the material tray, and rope tensioning and rope-retracting and -releasing are realized by three different mechanisms. The control system needs to coordinate the rope-retracting and -releasing mechanism with the movement of the embroidery frame during the tape embroidery operation, which has high control requirements and the control process may be more complicated.

[0004] In the applicant's prior invention patent CN 113584748 B, a feed rack and a feed lifting drive mechanism are added to the tape embroidery device. During the installation, the scheme also made corresponding changes to the presser foot lifting drive mechanism of the existing tape embroidery device, extending the guide column in the presser foot lifting drive mechanism so that it passes vertically through the housing, so that the end of the guide column is connected to the feed sleeve. In this way, the guide column is not only used as a guide rod of the pressure drop lifting drive mechanism, but also as a drive rod of the feed lifting drive mechanism. Since the two lifting drive mechanisms share the guide column, although the tape embroidery device is more compact to assemble, it cannot be directly assembled on the existing tape embroidery device. It is necessary to replace the existing guide column on the tape embroidery device with a longer guide column, and open a hole in the housing. In addition, the arrangement range of the feed transmission assembly and the feed drive motor is also limited by the location of the guide column. Moreover, during use, the feed lifting drive mechanism drives the guide column to rise and fall. Since the guide column passes through the two guide plates of the presser foot connecting member and the lifting drive member, there is a certain friction during the repeated movement, which will affect the stability of the guide column driven by the presser foot lifting drive mechanism to drive the presser foot to rise and fall in the vertical direction. Once the presser foot or the feed frame fails during the lifting process, causing the guide column to break, the realization of the presser foot lifting function and the feeding function will be affected at the same time. Summary of the invention

[0020] In order to more clearly illustrate the technical solutions in the embodiments of the present disclosure, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present disclosure. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0021] Figure 1 A schematic structural diagram of a tape embroidery device according to an embodiment of the present disclosure is shown; Figure 2 A schematic structural diagram of a feeding piece according to an embodiment of the present disclosure is shown; Figure 3 A schematic structural diagram showing a feeding member installed on a second sleeve through a mounting member according to an embodiment of the present disclosure is shown; Figure 4 A schematic diagram of the transmission structure between a feeding piece and a driving mechanism for driving the feeding piece to rotate and lift, and a presser foot and a presser foot lifting driving mechanism according to an embodiment of the present disclosure is shown. DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure.

[0023] The terms "first", "second", "third", etc. in the disclosure and claims of this disclosure and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0024] As mentioned above, the tape embroidery device requires a material tray to transport the tape (such as a rope or a belt) to the presser foot. The needle inserts into the embroidery material, and the upper thread locks the tape to the embroidery material. Continuous operation can complete the tape embroidery. During the tape embroidery operation, the upper thread locks the tape to the embroidery material. At this time, when the embroidery frame is moved, the embroidery frame will drive the tape to move. The tape will be pulled out of the material tray by the embroidery frame. The larger the material tray, the greater the pulling force, which may cause the embroidery to deform and result in defective embroidery.

[0025] In the applicant's prior invention patent, the tape embroidery device is equipped with a feed rack and its driving mechanism. Although the feed rack can be lifted or swung to pre-extract the tape from the material tray, and then the embroidery frame can be moved to avoid the tape between the embroidery frame and the material tray being stretched and excessively pulled when the embroidery frame moves. However, there are the following problems. On the one hand, since the guide column used in the presser foot lifting part needs to be used for multiple purposes, it is used as both a guide rod for the presser foot lifting part and a driving rod for the feed lifting. This requires changing the original guide column according to the needs of the feed lifting, and also requires opening a hole in the casing to adapt to the stroke of the feed lifting. In this way, it is impossible to simply add a feed rack and its driving mechanism to the existing tape embroidery device for use, and relevant modifications need to be made to the existing tape embroidery device. On the other hand, during use, the feed lifting drive mechanism drives the guide column to rise and fall. Since the guide column passes through the two guide plates of the presser foot connection member and the lifting drive member, there is a certain friction during the repeated movement, which will affect the stability of the guide column being driven by the presser foot lifting drive mechanism to drive the presser foot to rise and fall in the vertical direction. Once the presser foot or the feed frame fails during the lifting process, causing the guide column to break, the realization of the presser foot lifting function and the feeding function will be affected at the same time, and the presser foot and feeding parts need to be replaced at the same time, which has a high maintenance cost.

[0026] In view of this, according to the disclosed embodiment, a feed drive mechanism including a feed drive rod is designed, so that the presser foot lifting drive has its own independent guide column for presser foot lifting, and the feed lifting function is realized by an independent feed drive rod. In this way, a hole for the feed drive rod to pass through can be opened on the casing of the existing tape embroidery device, or no hole can be opened, and the feed drive mechanism can be directly installed on the existing tape embroidery device to realize the feeding function. In this way, not only does it not need to modify the structure of the presser foot part, but it is also not necessary to be limited by the inherent position of the guide column when installing the feed drive mechanism. Moreover, the feed lifting function and the presser foot lifting function are realized independently, and will not affect each other. The service life is long and the lifting stability is good. Once any part fails, the components of that part can be replaced and maintained separately.

[0027] Figure 1 FIG. 2 shows a schematic structural diagram of a tape embroidery device 10 according to an embodiment of the present disclosure. Figure 1 As shown, the coiling embroidery device 10 includes a housing 101, a needle bar portion, a presser foot portion, and a material tray portion 102. The needle bar portion includes a needle bar 103 and a needle bar driving mechanism, and the needle bar 103 is vertically arranged through the housing 101. The needle bar driving mechanism includes a cam and a connecting rod mechanism, which is used to drive the needle bar 103 to move up and down. The presser foot portion includes a presser foot mounting member 110, a presser foot sleeve 104, and a presser foot lifting driving mechanism. The presser foot sleeve 104 is sleeved outside the needle bar 103, and the presser foot mounting member 110 is connected to the presser foot sleeve 104. The presser foot mounting member 110 is used to install a presser foot and a nozzle (not shown in the figure, where the presser foot here is a presser foot for threading a belt, and the nozzle is used for threading a rope). The material tray portion 102 includes a material tray frame and a material tray, and a material tray (there can be one or more) is installed on the material tray frame. The material tray is used to transport ribbon-like objects such as ropes or belts to the place to be embroidered for coiling embroidery.

[0028] like Figure 1 As shown, the presser foot lifting drive mechanism comprises a presser foot driving motor 109-1 and a presser foot guide rod 109-2. The presser foot guide rod 109-2 is used for guiding the presser foot sleeve 104 when lifting, and the two are connected by a lifting driving member and a presser foot connecting member sleeved outside the presser foot guide rod 109-2. The presser foot connecting member has a driving fork part forked outside the presser foot sleeve 104. When the presser foot driving motor 109-1 drives the lifting driving member to lift, the lifting driving member moves along the length direction of the presser foot guide rod 109-2, and the presser foot connecting member also moves along the length direction of the presser foot guide rod 109-2, so that the presser foot sleeve 104 connected to the presser foot connecting member is also lifted and lowered, and the presser foot or nozzle connected to the presser foot sleeve 104 is also lifted and lowered.

[0029] like Figure 1As shown, the coiling embroidery device 10 further includes a rotary drive mechanism 111, which is mounted on the housing 101 and is used to drive the tray frame of the tray portion 102 to rotate. The tray frame is fixed on the first sleeve 105, which is sleeved outside the presser foot sleeve 104, and the first sleeve 105 is rotatably clamped on the housing 101 or the beam of the embroidery machine. The first sleeve 105 rotates under the drive of the rotary drive mechanism 1111, thereby driving the tray frame to rotate.

[0030] like Figure 1 As shown, the tape embroidery device 10 further includes a second sleeve 106, a feed piece 107, and a feed drive mechanism. The second sleeve 106 is sleeved on the first sleeve 105, and the feed piece 107 is installed on the second sleeve 106. The feed drive mechanism is arranged on the housing 101, and is used to drive the second sleeve 105 to move up and down, so as to drive the feed piece 107 to move up and down in the vertical direction, and realize the pulling and putting down of the tape during the lifting process. When the first sleeve 105 rotates under the drive of the rotary drive mechanism 111, the second sleeve 106 rotates under the drive of the first sleeve 105, so that the feed piece 107 rotates with the rotation of the material tray frame.

[0031] The feeding drive mechanism includes a feeding drive motor 108-1 and a feeding drive rod 108-2. One end of the feeding drive rod 108-2 is connected to the feeding drive motor 108-1, and the other end is connected to the second shaft sleeve 106. When the feeding drive motor 108-1 drives the feeding drive rod 108-2 to move up and down, the second shaft sleeve 106 connected to the feeding member 107 also moves up and down.

[0032] In some embodiments, the feed drive rod 108-2 can be arranged in the casing 101, and can be arranged at a certain distance from the presser foot guide rod 109-2, for example, it can be arranged on one side of the casing, and it can also be arranged on different sides of the casing. A through hole is provided in the casing 101 for the feed drive rod 108-2 to pass through, so that the lower end of the feed drive rod 108-2 can extend out of the casing 101 and connect with the second sleeve 105 located below the casing 101, and it can also facilitate the lifting movement of the feed drive rod. In some examples, a through hole is provided at the bottom of the casing 101 for the feed drive rod to extend out. In this example, the feed drive rod 108-2 can be shorter than the presser foot guide rod 109-2. In other examples, a through hole is provided at the bottom of the casing 101 for the feed drive rod 108-2 to extend out, and another through hole is provided at the crossbeam of the casing 101 for the feed drive rod 108-2 to extend out. In this example, the feed drive rod 108-2 can be equal to the length of the presser foot guide rod 109-2, or longer than the presser foot guide rod 109-2. Two through holes can limit the movement of the feed drive rod 108-2 to ensure that it can be raised and lowered in the vertical direction. Accordingly, the feed drive mechanism can be installed on the casing, such as a position with installation space inside or outside the casing. In some embodiments, considering the compactness of nearby driving and arrangement, the feed drive mechanism can be arranged on the side wall of the casing close to the feed drive rod.

[0033] In some embodiments, the feed drive rod can be arranged outside the housing, so that there is no need to open a through hole on the housing for it to pass through. In one example, the feed drive rod is installed on the outer side wall of the housing 101, or on the frame of the embroidery machine. Accordingly, the feed drive mechanism can be installed on the housing, for example, at a position with installation space inside or outside the housing. In some embodiments, considering the compactness of nearby driving and arrangement, the feed drive mechanism can be arranged on the side wall of the housing close to the feed drive rod.

[0034] In some embodiments, the feed drive rod 108-2 is a vertical rod, which is vertically arranged inside or outside the housing. In some embodiments, the feed drive rod 108-2 includes at least a vertical portion, which can be lifted and lowered in the vertical direction to drive the second sleeve 106 to lift and lower.

[0035] exist Figure 1 In the example shown, the feed drive rod 108-2 and the feed drive motor 108-1 can be compactly arranged on the tape embroidery device, and only a through hole is opened on the housing 101, and the presser foot lifting drive mechanism does not need to be modified, so that the device can be installed on the tape embroidery device 10. Figure 1The feed drive mechanism is arranged on the outer wall of the casing, and the feed drive motor 108-1 of the feed drive mechanism is located above the main shaft 112 passing through the coiling embroidery device. The feed drive motor 108-1 is connected to the feed drive rod 108-2 arranged in the casing 101 through the feed transmission assembly installed on the side wall of the casing. Accordingly, a through hole is provided at the bottom of the casing 101 to allow the feed drive rod 108-2 to pass through and move vertically, and a connecting block is provided on the side wall of the casing 101 to allow the feed transmission assembly and the feed drive rod 108-2 to pass through, so that the feed transmission assembly drives the connecting block to move in the through hole, and then the feed drive rod 108-2 can move up and down. Under the above arrangement, the feed drive motor 108-1 and the presser foot drive motor 109-1 are respectively located above and below the main shaft 112, so that the upper and lower spaces on the sides of the tape embroidery device are rationally utilized, so that after the feed drive mechanism is added, the overall arrangement of the tape embroidery device is compact, and no more installation space is occupied due to the addition of components. In this way, the same number of tape embroidery devices can be arranged on an embroidery machine as before the feeding function is installed.

[0036] like Figure 1 As shown, in some embodiments, the feeder 107 is configured according to the number of trays. That is, when there is one tray, one feeder is configured and is disposed close to the tray. When there are two trays, two feeders are configured, and each feeder is disposed close to one tray. Figure 1 As shown, the coiling and tape embroidery device 10 has two material trays, and two feeders 107 are respectively installed on both sides of the second sleeve 106. Like this, the rope or belt conveyed on the material tray can pass through the feeder 107 and be sent into the presser foot or the nozzle.

[0037] In some embodiments, the feeder 107 can be a feeder rack with a feeder hole in the prior invention patent, or a feeder ring. In one example, the feeder ring can be a closed ring, or an unclosed ring with a gap, such as a three-quarter ring or a semi-circular ring. In this way, the rope or belt can enter the feeder ring in any direction along the circumference of the ring surface, and can adapt to the material tray rotating, and the material enters from all directions as it rotates. At the same time, the ring surface can guide the material to move smoothly.

[0038] In some embodiments, the feed ring has an arc-shaped concave surface at the feed inlet, and the arc-shaped concave surface is horizontal and downward. Figure 1As shown, the strip generally enters from the top of the feed ring, is output from the bottom, and is then sent to the presser foot or nozzle below. The top entry is the feed port, and the bottom output is the discharge port. The end face of the feed port of the feed ring is an arc end face, and the arc end face extends downward toward the center of the feed port, so that the caliber at the feed port gradually decreases, and the whole is concave, which is defined as an arc-shaped concave surface in the disclosed embodiment. In this way, a strip of material with a certain width can enter from the arc-shaped concave surface at the feed port, and the arc-shaped concave surface can facilitate the strip to enter smoothly and flatten, and at the same time, the presser foot or nozzle is introduced downward along the direction of the arc-shaped concave surface (mainly horizontally downward). In some examples, the strip can enter the feed ring obliquely, and be vertically guided out of the feed ring, and then inserted into the presser foot or nozzle.

[0039] In some embodiments, the arc-shaped concave surface of the feed ring is arranged toward the corresponding material tray on the material tray frame. This can facilitate the guiding of the tape material into and output to the presser foot or nozzle of the presser foot part. In one example, the feed ring can be vertically installed on the tape embroidery device 10. For example, the feed inlet and the discharge port of the feed ring are arranged on the same vertical line. In another example, the feed ring can be tiltedly installed on the tape embroidery device. For example, the feed inlet is arranged close to the material tray on the same side, and the discharge port is arranged close to the rotation center of the material tray.

[0040] Figure 2 The schematic diagram of the structure of the feeding member 107 according to the embodiment of the present disclosure is shown. The feeding member 107 is a feeding ring, which can be a feeding sleeve structure, and has an arc-shaped concave surface 107-1. The strip enters from the arc-shaped concave surface 107-1 of the feeding ring and is guided downward. With the arc-shaped guidance, the strip is flattened, and after being guided through the line along the direction of the arc-shaped concave surface, the strip can be guided vertically downward. Figure 2 In one example, the feed ring has a certain thickness, which can better guide the strip to be led out in a flat state. In another example, the feed ring can be a thin-sheet ring. Figure 2 In the example shown, the feed ring includes an upper ring portion and a lower ring portion, and the outer diameter of the upper ring portion is greater than the outer diameter of the lower ring portion. In some embodiments, the feed ring can also be a ring of other structural forms, such as a cylindrical ring formed by equal outer diameters of the upper and lower ring portions.

[0041] The disclosed embodiment designs a feeding ring with a simple structure to replace the feeding rack of the prior invention patent, so that when it is installed on the tape embroidery device, the tape material can be pulled out from the material tray and fed into the feeding ring, and the feeding ring can output the flattened tape material to the presser foot, ensuring that the tape material locked by the surface thread is smooth and the embroidery quality is high.

[0042] Figure 3 FIG. 1 shows a schematic diagram of a structure in which the feeding member 107 is installed on the second sleeve 106 through the mounting member 113 according to an embodiment of the present disclosure. Figure 3As shown, the mounting member 113 can be a mounting plate, which is fixed on the second sleeve 106, for example, it can be fixed on the outside of the second sleeve 106, or it can be fixed on the inside of the second sleeve. In some embodiments, the mounting member 113 also has a mounting hole, allowing the feeder 107 to be sleeved in the mounting hole. The feeder 107 can cooperate with the mounting hole without relative rotation. In some embodiments, the mounting member 111 can also be welded to the feeder 107, or screwed and fixed, or screwed.

[0043] In some embodiments, the mounting member 113 can be used to tilt the feed member 107. In this way, the arc-shaped concave surface of the feed member 107 can face the feed tray. In one example, the mounting member 113 can be an obtuse-angle connector or a connector of other forms. In some embodiments, the mounting member 113 can be used to vertically mount the feed member 107. The mounting member 113 can be a right-angle connector or a connector of other forms.

[0044] In some embodiments, there are several feeding members 107, and each feeding member is mounted on the second sleeve 106 corresponding to a tray on the tray rack. In some examples, each feeding member is mounted on the second sleeve 106 via a mounting member, for example Figure 3 In some examples, several feeders can be mounted on the second sleeve 106 via a mounting member. In one example, the mounting member can be an annular plate for fixing several feeders.

[0045] Figure 4 The figure shows a schematic diagram of the transmission structure between the feeding member and the driving mechanism for driving the feeding member to rotate and lift, and the presser foot and the presser foot lifting driving mechanism according to an embodiment of the present disclosure. Figure 4 As shown, the feeding drive mechanism includes a feeding drive motor 108-1, a feeding transmission assembly 108-3, and a feeding drive rod 108-2. The motor shaft of the feeding drive motor 108-1 drives the feeding transmission assembly 108-3 to transmit, and then drives the feeding drive rod 108-2 connected to the feeding transmission assembly 108-3 to move up and down. Among them, the feeding transmission assembly 108-3 can be implemented by a transmission component such as a pulley or a sprocket, and its transmission structure can be arranged in a triangular shape as shown in the figure, or it can be arranged vertically in an elliptical shape, etc. In one example, the feeding transmission assembly 108-3 is composed of a conveyor belt, a driving wheel, and a driven wheel. The feeding drive motor 108-1 drives the driving wheel to rotate, and the driven wheel rotates under the transmission of the conveyor belt. The feeding transmission assembly 108-3 is connected to one end of the feeding drive rod 108-2, and the feeding drive rod 108-2 can be controlled to rise and fall during the transmission process of the conveyor belt. The other end of the feeding drive rod 108-2 is connected to the second sleeve 106 (for example, via Figure 4The driving fork structure in the feeding drive rod 108-2 realizes the connection between the feeding drive rod 108-2 and the second shaft sleeve 106), and the other end of the feeding drive rod 108-2 is lifted and lowered with the second shaft sleeve 106. Correspondingly, the feeding member 107 connected to the second shaft sleeve 106 is also lifted and lowered.

[0046] like Figure 4 As shown, the presser foot lifting drive mechanism includes a presser foot lifting drive motor 109-1, a presser foot guide rod 109-2, a presser foot transmission assembly 109-3, and a presser foot connector. The presser foot connector is sleeved on the outside of the presser foot guide rod 109-2. The presser foot connector is also connected to the presser foot sleeve 104. Figure 4 In the example, the presser foot guide rod 109-2 is also provided with a lifting drive member, and the presser foot transmission assembly 109-3 is used to drive the lifting drive member to move up and down. When the lifting drive member is driven by the presser foot transmission assembly 109-3 to move up and down along the presser foot guide rod, the lower guide plate of the lifting drive member drives the presser foot connector to move upward along the presser foot guide rod, so that the presser foot sleeve 104 is moved upward by the presser foot connector, and the presser foot or nozzle is raised; the upper guide plate of the lifting drive member drives the presser foot connector to move downward along the presser foot guide rod, so that the presser foot sleeve 104 is moved downward by the presser foot connector, and the presser foot or nozzle is lowered. In other examples, the presser foot transmission assembly 109-3 directly drives the presser foot connector to move up and down. When the presser foot connector rises along the presser foot guide rod, it rises with the presser foot sleeve 104, and vice versa.

[0047] In some embodiments, the presser foot connector is connected to the presser foot sleeve by a connection structure of a driving fork. In one example, the presser foot connector has a first connecting sub-component and a second connecting sub-component, which are connected together. The first connecting sub-component is sleeved on the presser foot guide rod, and the second connecting sub-component has an annular opening, which is engaged with the annular groove of the presser foot sleeve 104.

[0048] In some embodiments, the presser foot transmission assembly 109-3 can be implemented by using a transmission component such as a pulley or a sprocket, and its transmission structure can be arranged in a triangular shape as shown in the figure, or can be arranged vertically in an elliptical shape, etc. The presser foot drive motor 109-1 drives the active wheel to rotate, and the driven wheel rotates under the transmission of the conveyor belt. The presser foot transmission assembly 109-3 is connected to the lifting drive member in a transmission manner, and the lifting and lowering of the lifting drive member can be controlled during the transmission process of the conveyor belt. In some examples, the presser foot transmission assembly 109-3 adopts a triangular transmission structure, so that the transmission of the presser foot transmission assembly can be more stable. In addition, the presser foot drive motor that drives the active wheel can be retracted and arranged between adjacent heads of the embroidery machine to avoid interfering with the front embroidery operation.

[0049] like Figure 4As shown, the rotary drive mechanism includes a rotary drive motor 111-1, a transmission rod 111-2, and a transmission assembly 111-3. In some embodiments, the transmission assembly can adopt a transmission structure of a master and slave pulley. The transmission assembly 111-3 includes a driving wheel, a belt, and a driven wheel. The rotary drive motor 111-1 drives the transmission rod 111-2 to rotate, and then the transmission assembly 111-3 connected to the transmission rod 111-2 also rotates accordingly, and the first sleeve 105 connected to the driven wheel also rotates accordingly to drive the material tray frame to rotate, and the feeder 107 installed on the second sleeve 106 to rotate. In some embodiments, the rotary drive mechanism can be used alone for the rotation of the material tray, that is, as a material tray rotation drive mechanism, and accordingly, the rotation of the presser foot is realized by another set of presser foot rotation drive mechanism. For example, in the applicant's prior invention patent CN113584748B, the presser foot rotation drive mechanism includes a presser foot drive motor and a transmission assembly. The presser foot drive motor drives the transmission assembly to move, and then drives the presser foot sleeve to rotate, so as to drive the presser foot or nozzle to rotate. In some embodiments, a rotary drive mechanism is used, which can simultaneously drive the presser foot or nozzle and the material tray frame to rotate synchronously. The rotary drive motor drives the transmission assembly to drive the first shaft sleeve to rotate, and the presser foot sleeve rotates with the first shaft sleeve to drive the presser foot or nozzle of the presser foot part to rotate. At the same time, the material tray frame is installed on the first shaft sleeve, and the material tray frame and the feeding frame also rotate synchronously.

[0050] The embodiment of the present disclosure also provides an embroidery machine, including an embroidery frame and a plurality of embroidery machine heads. The plurality of embroidery machine heads include a plurality of flat embroidery device heads and a plurality of tape embroidery device heads. The tape embroidery device can be used Figure 1 The tape embroidery device 10 shown. The main shaft 112 drives the needle bars between the multiple machine heads (flat embroidery devices) to move synchronously. The main shaft 112 is also connected to the camshaft on the tape embroidery device, and then the cam and connecting rod mechanism are driven by the power of the main shaft 112 to realize the movement of the needle bar on the tape embroidery device. When the tape embroidery device and the flat embroidery device are set together on a computer embroidery machine, the tape embroidery device is prevented from moving with the flat embroidery device to cause mechanical wear and loose threads. The tape embroidery device also includes a separation mechanism, so that when the flat embroidery is in operation, the tape embroidery device 10 can be disengaged from the main shaft 112 and stop rotating.

[0051] The embodiment of the present disclosure also provides a method for controlling the feeding of tape embroidery. The method is implemented based on the tape embroidery device of the embodiment of the present disclosure. The method is executed by a controller at the embroidery machine end. In some embodiments, the method includes controlling the machine needle to insert the needle into the embroidery material so that the rope or belt is locked on the embroidery material by the surface thread. The method also includes controlling the feeding drive mechanism to drive the feeding piece to lift so as to pull out the rope or belt on the material tray. The method also includes controlling the machine needle to lift away from the embroidery material. The method also includes controlling the embroidery frame to move so as to pull the rope or belt to move, and synchronously controlling the feeding drive mechanism to drive the feeding piece to descend so as to lower the rope or the belt pulled out from the material tray. In addition, the method also includes controlling the machine needle to insert the needle into the embroidery material again, and repeating the above steps until the tape embroidery is completed.

[0052] In some embodiments, the method includes controlling the needle to penetrate the embroidery material so that the rope or belt is locked on the embroidery material by the upper thread. The method also includes controlling the feed drive mechanism to drive the feed piece to lift so as to pull out the rope or belt on the material tray. The method also includes controlling the needle to lift away from the embroidery material. The method also includes first controlling the feed drive mechanism to drive the feed piece to descend so as to lower the rope or belt pulled out from the material tray, and then controlling the embroidery frame to move. In addition, the method also includes controlling the needle to penetrate the embroidery material again, and repeating the above steps until the tape embroidery is completed.

[0053] In this way, when the needle is controlled to penetrate the embroidery material, the rope or belt is locked by the surface thread. At this time, the feed drive mechanism is used to control the feed part to move upward, so that the rope or belt on the material tray is pulled out from the material tray. After that, the needle is controlled to move upward to leave the embroidery material and move the embroidery frame. The feed part can release the thread when moving downward, and the embroidery frame pulls the rope or belt to move, which can solve the problem that a large mechanical pulling force is generated when the embroidery frame moves due to the increase in the size of the material tray, which will then deform the embroidery and cause poor embroidery. In addition, the embodiment of the present disclosure uses two rods as the guide rod for the presser foot lifting and the feed drive rod for the feed lifting, respectively, which can ensure that the presser foot lifting function and the feed lifting function do not interfere with each other, and ensure that the above operations are carried out smoothly and steadily.

[0054] Furthermore, when the feeding piece is designed as a feeding ring, it can introduce the rope or belt conveyed by the material tray from any circumferential angle and lead it out in a flattened state, can smoothly guide and pull the rope or belt, adapt to the dynamic pulling process when the material tray rotates, can convey a smooth rope or belt to the presser foot or nozzle, and the conveyed rope is not subjected to a large pulling force or pressure due to the rotation of the material tray, ensuring that the embroidery will not be deformed due to pulling, thereby improving the quality of the embroidery.

[0055] The embodiments described above are merely preferred embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various modifications and improvements made to the technical solutions of the present disclosure by ordinary technicians in this field should fall within the protection scope of the claims of the present disclosure.
