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 material tray structure for tape embroidery and an installation method thereof, a tape embroidery device, and an embroidery machine. Background Art

[0002] A tape embroidery system is used to embroider ribbons and / or cords. It typically consists of a housing, a drive spindle, a needle bar, a feed unit, a presser foot, and a thread take-up lever. The feed unit currently uses a material tray to carry the material, which is mounted on the sleeve of the tape embroidery system via a mounting bracket. During the tape embroidery operation, the needle lowers the needle into the material, and the upper thread locks the cord or ribbon fed from the tray to the material. At this point, moving the embroidery frame moves the cord / ribbon.

[0003] In some related technologies, the mounting frame has an openable and retractable structure. When the structure is opened, one end of the connecting shaft on the mounting frame is exposed, allowing the material tray to be inserted through this end and placed outside the connecting shaft. The opening and retractable structure is then closed, sealing the exposed end of the connecting shaft, completing the assembly of the material tray and the mounting frame. This structure is relatively complex and inconvenient for installing and replacing the material tray.

[0004] In some related technologies, the material tray is fixed to the mounting frame via a rotating plunger. Although this structure is simple, since the material tray is fixed or removed by the elastic fit between the rotating plunger and the mounting frame, it is not only laborious to install, but also the installation accuracy of the rotating plunger affects the installation accuracy of the material tray on the mounting frame. If there is a positional deviation between the fixing positions of the two ends of the material tray, the material tray may be installed tilted on the mounting frame, or even unable to be installed. Summary of the Invention

[0005] One or more embodiments of the present disclosure provide a material tray structure for tape embroidery and an installation method thereof, a tape embroidery device, and an embroidery machine, aiming to solve one or more of the above-mentioned problems and other potential problems.

[0006] First, embodiments of the present disclosure provide a material tray structure for tape embroidery. The material tray structure includes a mounting bracket and a material tray, the mounting bracket being connected to the material tray. The mounting bracket is provided with a slot, into which the material tray is engaged via the material tray shafts at both ends, so that the material tray shafts are constrained within the slots. The material tray structure for tape embroidery according to embodiments of the present disclosure is not only simple in structure and easy to disassemble, assemble, and replace, but also meets the requirements for rapid and stable rotation of the unloading material tray during high-speed tape embroidery operations.

[0007] In some embodiments, the tray and the tray shaft are assembled into one piece.

[0008] In some embodiments, the tray shaft is fixed on the tray, or the tray shaft is rotatably disposed on the tray.

[0009] In some embodiments, the slot width is greater than the diameter of the tray shaft.

[0010] In some embodiments, the card slot is opened downward from the upper edge of the mounting frame, and the slot body portion connected to the slot bottom is vertically arranged or offset toward the rotation center of the material tray.

[0011] In some embodiments, the mounting bracket is provided with a limit member, which is used to limit the tray shaft from disengaging from the slot.

[0012] In some embodiments, the limiting member is an elastic limiting member.

[0013] In some embodiments, the elastic limit member is installed on the mounting bracket, and the free end of the elastic limit member at least partially interferes with the slot, so that the width of the channel formed between the slot wall of the slot and the free end of the elastic limit member is smaller than the diameter of the tray shaft, so as to limit the tray shaft from detaching from the slot.

[0014] In some embodiments, the mounting frame includes a first mounting frame and a second mounting frame, the first mounting frame is used to be mounted on the tape embroidery machine head, the second mounting frame is connected to the first mounting frame, and the card slot is opened on the second mounting frame.

[0015] In some embodiments, the second mounting frame has at least two mounting arms, and the tray shafts at both ends of the tray are installed between two adjacent mounting arms.

[0016] In a second aspect, the embodiments of the present disclosure further provide a tape embroidery device, which includes a tape embroidery machine head and a material tray structure for tape embroidery according to the first aspect.

[0017] In some embodiments, the mounting frame is mounted outside the shaft sleeve of the tape embroidery machine head, and the tape embroidery machine head is provided with a rotating mechanism for driving the shaft sleeve to rotate.

[0018] In a third aspect, the present disclosure further provides an embroidery machine, which includes the tape embroidery device according to the second aspect.

[0019] Fourthly, embodiments of the present disclosure further provide a method for installing a material tray structure for tape embroidery. The method includes installing a mounting bracket for the material tray structure onto a shaft sleeve of a tape embroidery machine head. The method also includes engaging the material tray of the material tray structure with a material tray shaft at each end thereof into a retaining slot, such that the material tray shaft is restrained within the retaining slot.

[0020] In some embodiments, the method further includes assembling the tray shaft and the tray into one piece before the tray of the tray structure is clamped into the clamping slot through the tray shafts at both ends of the tray. BRIEF DESCRIPTION OF THE DRAWINGS

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 any creative work.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] The term "including" and its variations used in this document indicate open inclusion, that is, "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one other embodiment". Terms such as "upper", "lower", "front", and "rear" indicating placement or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the principles of the present disclosure, and do not indicate or imply that the referred elements must have a specific orientation, be constructed or operate in a specific orientation, and therefore should not be understood as limiting the present disclosure.

[0025] As previously mentioned, the material tray is mounted on the tape embroidery device via a mounting bracket. The tray serves as the feed unit, conveying the tape material so that the upper thread can be used to lock the tape material onto the embroidery material during the tape embroidery operation. To facilitate tape replacement, the tray and mounting bracket are typically designed to be removable. Furthermore, consideration must be given to ensuring that the installed tray can maintain stable tape delivery during rapid rotation during tape embroidery.

[0026] In some related technologies, the mounting frame adopts a closed structure. When the material tray needs to be installed, the mounting frame is opened via an opening and closing mechanism, exposing the connecting shaft, allowing the material tray to be inserted and installed. The opening and closing mechanism is then closed, allowing the exposed connecting shaft and the opening and closing mechanism to form a closed structure again. This structure not only allows the opening and closing mechanism to be opened and closed as needed to install or remove the material tray, but also prevents the material tray from detaching from the mounting frame during rapid rotation, ensuring stable embroidery material transport. However, this material tray structure is relatively complex and requires a well-designed opening and closing mechanism to work with it. On the one hand, this opening and closing mechanism requires specific design and precise assembly to ensure that the opening and closing mechanism effectively seals the material tray after it is installed on the connecting shaft, preventing it from detaching from the connecting shaft due to the opening of the opening and closing mechanism during rotation. On the other hand, each time the material tray is installed or removed, the opening and closing mechanism must be opened and closed repeatedly, making installation and removal cumbersome and inconvenient. This is particularly cumbersome and inefficient when multiple tape embroidery devices are installed on a single embroidery machine.

[0027] To address this issue, according to embodiments of the present disclosure, a material tray structure for tape embroidery is provided, featuring a simple structure and easy assembly and disassembly. The mounting frame of this material tray structure does not require an opening and closing mechanism. The material tray can be quickly installed by snapping the material tray shafts at both ends into the slots on the mounting frame. The material tray can also be quickly removed by detaching the material tray shafts from the slots. Furthermore, because the slots limit the free space for the material tray shafts to move, even if the material tray rotates rapidly during tape embroidery, it is unlikely to detach from the mounting frame's slots, ensuring stable material conveyance.

[0028] Figure 1 FIG. 1 shows a schematic structural diagram of a material tray structure 10 for tape embroidery according to an embodiment of the present disclosure. Figure 1 As shown, the material tray structure 10 may include a material tray 102 and a mounting frame 101. The material tray 102 is detachably connected to the mounting frame 101. A slot 101-1 is provided on the mounting frame 101, and the material tray 102 is inserted into the slot 101-1 through the material tray shafts 103 at both ends thereof, and the material tray shaft 103 is restricted in the slot 101, so that the material tray rotates during the tape embroidery operation, and the material tray can still be firmly mounted on the mounting frame, and can stably convey the tape material. In the example in the figure, there are two material trays, which are respectively provided on both sides of the mounting frame 101. In some embodiments, one material tray can be provided, which is provided on one side of the mounting frame. In some embodiments, three or even more material trays can be provided, and the number is set according to needs, and the material trays are evenly distributed on the mounting frame.

[0029] In some embodiments, the width of the slot 101 - 1 is greater than the diameter of the tray shaft 103 , so that the tray shaft can be inserted into the slot 101 .

[0030] In order to prevent the tray shaft 103 from being separated from the slot 101-1, the slot 101-1 can be configured as an inclined straight slot, for example Figure 1 In addition, the slot 101-1 can also be set as a non-straight slot, which can be a multi-layer rotary slot or a curved slot. Based on the principle that the material tray axis will not be separated from the slot due to the centrifugal force during the rotation of the material tray, it can be designed according to needs but not limited to Figure 1 In some embodiments, the slot opening of the slot 101-1 may be provided at an edge of the mounting frame (such as a lower edge, a side edge, or an upper edge), and the entire slot body from the slot opening to the bottom of the slot may be connected in a straight structure, or in a rotary structure or a curved structure.

[0031] In some embodiments, when the slot opening of the card slot 101-1 is located at the upper edge of the mounting frame 101, the slot body portion connected to the slot bottom can be set vertically or offset toward the rotation center of the material tray 102 (referring to the rotation center of the material tray when rotating during the tape embroidery operation). When set vertically, the entire slot body between the slot opening and the slot bottom can be a non-straight slot or a straight slot (a corresponding limiting structure can be set to prevent the material tray axis from disengaging from the slot in the vertical direction during rotation). When set offset toward the rotation center of the material tray 102, the entire slot body between the slot opening and the slot bottom can be a straight slot or a non-straight slot. In one example, the card slot 101-1 is opened downward from the upper edge of the mounting frame 101, and the entire slot body between the slot opening and the slot bottom is an inclined straight slot, and the slot opening is offset relative to the slot bottom in the vertical direction close to the rotation center of the material tray 102. The card slot structure in this example is simple and convenient for quick assembly. Figure 1 In the example, the mounting frame 101 is provided with a slot 101-1 with the notch facing upward, and the portion of the mounting frame 101 on which the tray shaft 103 is mounted is a hook-shaped structure (depending on the setting position and shape of the slot, the portion of the mounting frame 101 on which the tray shaft 103 is mounted is not limited to a hook-shaped structure), the tray shaft 103 is inserted into the slot 101-1 and is restricted in the vertical direction by the hook-shaped structure, so that the tray shaft 103 is not easily separated from the slot 101-1 in the vertical direction.

[0032] In some embodiments, the tray shaft 103 and tray 102 are pre-assembled into a single piece. The assembled tray 102 is then inserted into two retaining slots 101-1 on the mounting frame 101 via the tray shaft 103 at both ends, thereby securing the tray 102 to the mounting frame 101. Accordingly, the tray 102 can be removed from the mounting frame 101 by disengaging the tray shaft 103 from the two retaining slots 101-1 on the mounting frame 101. After removal, the tray shaft 103 and tray 102 are assembled into a single, integrated structure. In other embodiments, the tray shaft 103 and tray 102 are integrally formed, in which case the tray shaft 103 is fixed relative to the tray 102.

[0033] Figure 2 The diagram shows a structural diagram of a feed tray 102 and a feed tray shaft 103 assembled into one piece according to an embodiment of the present disclosure. In some embodiments, the feed tray shaft 103 is fixedly mounted on the feed tray 102. In some embodiments, the feed tray shaft 103 is rotatably mounted on the feed tray 102. In this way, the feed tray 102 is movable relative to the feed tray shaft 103 and can rotate in a circular direction.

[0034] In some embodiments, the tray shaft 103 can be a whole shaft that passes through both ends of the tray 102 and is fixedly or rotatably connected to the tray. In some embodiments, the tray shaft 103 can be two segmented shafts, respectively disposed at both ends of the tray, and the axes of the two segmented shafts are coaxial.

[0035] In some embodiments, the portion of the tray shaft 103 extending from the ends of the tray is designed to engage with the slots 101-1, while the portion not extending from the ends is used for winding the strip. In some embodiments, a rotating shaft is provided outside the tray shaft, with a diameter smaller than the rotating shaft, connecting the two tray surfaces. The tray shaft can be a single, integral shaft extending through the rotating shaft to the ends of the tray, or it can be two segmented shafts, disposed at each end of the rotating shaft and located outside the ends of the tray surfaces. The rotating shaft is used for winding the strip.

[0036] In some embodiments, the material tray 102 may be composed of two disk surfaces and a rotating shaft / material tray shaft connecting the disk surfaces. In some embodiments, the material tray 102 may be composed of a cylindrical disk body.

[0037] Figure 3 A schematic diagram of the structure of a mounting frame 101 according to an embodiment of the present disclosure is shown. The mounting frame 101 may include a first mounting frame 101-2 and a second mounting frame 101-3. The first mounting frame 101-2 is used to mount the material tray structure on the tape embroidery machine head. The second mounting frame 101-3 is connected to the first mounting frame 101-2, and the card slot 101-1 is provided on the second mounting frame 101-3. In some embodiments, the first mounting frame 101-2 and the second mounting frame 101-3 are provided separately and fixed by a fixing member. In some embodiments, the first mounting frame 101-2 and the second mounting frame 101-3 are an integrated frame structure.

[0038] In some embodiments, the second mounting frame 101-3 has at least two mounting arms 101-3A and 101-3B, each with a slot disposed on opposing sides of the two mounting arms 101-3A and 101-3B. The tray shafts 103 at both ends of the tray 102 can be mounted between two adjacent mounting arms 101-3A and 101-3B, allowing the second mounting frame 101-3 to mount at least one tray. In one example, the second mounting frame 101-3 has four mounting arms, with two mounting arms 101-3A and 101-3B positioned on the same side for mounting one tray 102, and the other two mounting arms positioned on the same side for mounting another tray.

[0039] In some embodiments, the second mounting bracket can be a single-piece bracket having at least two mounting arms. In some embodiments, the second mounting bracket can include multiple split brackets. In one example, a split bracket has mounting arms on both sides, and the two mounting arms on the same side of the two split brackets are used to mount a single feed tray. In another example, a split bracket has one mounting arm. When there are four split brackets, the two mounting arms of the two split brackets can mount a single feed tray.

[0040] In certain embodiments, the first mounting frame can be an integral support with a center having a notch for allowing the sleeve on the coiling embroidery device to pass through. In certain embodiments, the first mounting frame can be a plurality of split supports for mounting the split second mounting frame outside the sleeve.

[0041] In order to more clearly describe the application environment of the material tray structure 10 in the tape embroidery device, the following will be combined with Figure 4 Part of the structure of the tape embroidery device is described in detail. Figure 4 A three-dimensional structural diagram of a tape embroidery device 30 including the above-mentioned material tray structure 10 according to an embodiment of the present disclosure is shown.

[0042] Figure 4 The tape embroidery device 30 shown in FIG. 1 may include at least a tape embroidery head 40 and the aforementioned material tray structure 10. The tape embroidery head 40 may include a housing, a needle bar unit and its drive mechanism, a presser foot unit and its drive mechanism, and other components. The needle bar of the needle bar unit extends vertically through the housing. The presser foot sleeve and shaft sleeve 41 are sequentially attached to the needle bar. The material tray structure 10 is secured to the shaft sleeve 41. For example, the mounting bracket 101 of the material tray structure 10 is mounted outside the shaft sleeve 41.

[0043] The coiling embroidery device 30 may further include a rotating mechanism for driving the shaft sleeve 41. The rotating mechanism may be a rotating mechanism that drives the material tray 102 and the presser foot connected to the presser foot sleeve to rotate synchronously, or a rotating mechanism that drives the material tray 102 and rotates independently of the presser foot. For example, reference may be made to the applicant's prior patent application CN113584749B or other independent driving methods.

[0044] Through the above-mentioned embodiments, the present disclosure redesigns the material tray structure 10, simplifies the material tray structure and installation method, and also ensures that the material tray can still stably convey the material during rotation. In addition, this design simplifies the difficulty of material tray installation and reduces the assembly requirements of the installer, further improving the efficiency of disassembly and assembly.

[0045] It should be understood that the tray structure of the above embodiment is only exemplary. Figure 5 An embodiment of one of the other structures is described in more detail. Figure 5 A schematic diagram of a material tray structure 20 for tape embroidery according to another embodiment of the present disclosure is shown. The material tray structure 20 comprises a mounting frame 201 and a material tray 202. Mounting frame 201 is provided with a slot 201-1. Material tray 202 is engaged with slots 201-1 via material tray shafts 203 at both ends. The material tray 202 is constrained by slots 201-1 and is difficult to disengage. Figure 5 Example with Figure 1 The difference of the example is that a limiting member 204 is provided on the mounting frame 201, and the limiting member 204 is used to further limit the material tray shaft 203 from being separated from the slot 201-1.

[0046] In some embodiments, the stopper is an elastic stopper mounted on the mounting bracket 201. One free end of the stopper at least partially interferes with the slot 201-1, ensuring that the width of the channel formed between the slot wall of the slot 201-1 and the free end of the elastic stopper is smaller than the diameter of the tray shaft 203. This prevents the tray shaft 203 from dislodging from the slot 201-1. The stopper 204 blocks the path of the tray shaft 203 from potentially dislodging from the slot 201-1, preventing it from dislodging from the bottom of the slot toward the notch. Furthermore, the elastic properties of the stopper 204 allow the tray shaft 203 to return to its original position relatively gently.

[0047] In some examples, the elastic stopper 204 can be fixed to a side surface of the mounting frame 201, either the outer or inner side surface, and the active end of the elastic stopper 204 can be arranged on the side surface of the mounting frame and partially or completely cover the card slot 201-1, or can extend into the card slot 201-1. In some examples, the elastic stopper 204 can be fixed to a slot wall of the card slot 201-1, and its active end can be located within the card slot 201-1, and can extend to or toward the other slot wall of the card slot 201-1.

[0048] In some examples, the active end of the elastic limiting member 204 can be in clearance fit with the tray shaft 203, or can be in contact with the tray shaft 203. In some examples, the active end of the elastic limiting member can be an arc-shaped active end, which is convenient for acting on the tray shaft 203 that is about to leave the bottom of the tank.

[0049] In some examples, the elastic stopper 204 may be a spring. Figure 5 As shown, one end of the spring (or other position of the spring except the end) is fixed on the mounting arm of the mounting bracket 201, and the other end is the active end and partially blocks the card slot 201-1.

[0050] In some examples, elastic stoppers 204 are provided on both sides of the mounting frame 201, corresponding to the tray shafts 203 at both ends of each tray 202. These stoppers can be mounted on the two mounting arms 201-3A and 201-3B of the second mounting frame 201-3. This stabilizes the tray shafts 203 at both ends of the tray 202, preventing the situation where one end of the tray shaft 203 is disengaged from the retaining slot 201-1 while the other end remains in the retaining slot 201-1.

[0051] In some embodiments, the stopper can also be a non-elastic pin, configured as a switch on the mounting frame. In one example, the pin is fixed to the mounting frame. After the tray 202 is mounted on the mounting frame 201, the pin is rotated so that its free end partially or completely blocks the slot 201-1. Alternatively, the pin rotates and cooperates with the mounting frame to form a latch that completely blocks the slot 201-1. In this way, the pin blocking the slot 201-1 prevents the tray shaft 203 from dislodging from the bottom of the slot toward the notch.

[0052] In addition, the tray structure 20 can also refer to Figure 4 The embroidery machine is mounted on a coiling embroidery device. The coiling embroidery device may further include at least a coiling embroidery machine head and the material tray structure 20. The material tray structure 20 is fixed on the shaft sleeve of the coiling embroidery machine head. For example, the mounting frame 201 of the material tray structure 20 is mounted outside the shaft sleeve.

[0053] The disclosed embodiment also provides an embroidery machine, comprising an embroidery frame and a plurality of embroidery machine heads. The plurality of embroidery machine heads include a plurality of heads for flat embroidery devices and a plurality of heads for tape embroidery devices. The tape embroidery device can adopt a tape embroidery device equipped with a material tray structure 10, 20. The needle bars of the multiple heads (flat embroidery devices) are driven by a main shaft to move synchronously. The main shaft is also connected to the camshaft on the tape embroidery device, and then the main shaft power drives the cam and connecting rod mechanism to realize the movement of the needle bar on the tape embroidery device. When the tape embroidery device and the flat embroidery device are arranged together on a computer embroidery machine, the problem of mechanical wear and loose thread caused by the tape embroidery device when the flat embroidery device is in operation is avoided. The tape embroidery device also includes a separation mechanism, so that the tape embroidery device can be disengaged from the main shaft and stop rotating when the flat embroidery is in operation.

[0054] The disclosed embodiments also provide a method for installing a tray structure. The method includes installing a mounting bracket for the tray structure onto a shaft sleeve of a tape embroidery machine head. The method also includes inserting the tray structure's tray shafts into slots at both ends of the tray shaft, such that the tray shafts are confined within the slots.

[0055] Furthermore, the method includes integrally assembling the tray shaft with the tray structure before the tray shafts at both ends engage the slots. This allows the tray to be installed in one step by engaging the tray shafts into the slots of the mounting bracket. When multiple heads on an embroidery machine utilize this mounting method, operators can quickly and accurately install and disassemble the entire machine without requiring complex operations or extensive installation experience.

[0056] 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 scope of protection determined by the claims of the present disclosure.
