Description

Technical Field

[0001] This invention relates to the field of computerized embroidery machine technology, and in particular to a loop-making wheel mechanism for a rope embroidery device, a rope embroidery device, and a computerized embroidery machine. Background Technology

[0002] To adapt to the challenges of increasing product diversity brought about by people's growing daily needs, the existing rope embroidery on the market can only complete single-color rope embroidery with a single device. To complete the production of multi-color rope embroidery patterns, it is necessary to change the rope or combine multiple devices, which will increase the number of processes, increase the labor intensity of operators, increase processing time, and reduce product output. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] According to an embodiment of the first aspect of the present invention, a looping wheel mechanism for a rope embroidery device includes a looping wheel assembly, wherein the looping wheel assembly is provided with a rope receiving portion and a rope locking portion.

[0005] The locking rope portion moves relative to the accommodating rope portion to have a first switching position and a second switching position. When the locking rope portion is in the first switching position, the rope can enter the accommodating rope portion. When the locking rope portion is in the second switching position, the locking rope portion locks the rope in the accommodating rope portion.

[0006] When the switching component reciprocates along the axial direction of the wheel body, the wheel body has a groove formed by a recess in the end face of the wheel body. A first through hole is provided on the side wall of the wheel body, which communicates with the groove. The combination of the first through hole and the groove constitutes the rope-accommodating portion.

[0007] The rope embroidery device is connected to the head shell of the computer embroidery machine.

[0008] In this embodiment, the loop-making wheel mechanism is provided with a rope-accommodating part and a rope-locking part. The rope-locking part moves relative to the rope-accommodating part and has a first switching position and a second switching position. This helps the loop-making wheel assembly to cooperate with the gripper assembly of the rope-clamping mechanism, thereby realizing automatic rope threading of the loop-making wheel assembly, reducing the labor intensity of the operator, and improving the efficiency of rope embroidery.

[0009] In some embodiments of the present invention, the wheel is cylindrical, and the switching component includes a first arc-shaped plate that is adapted to the inner surface of the slide groove so that the first arc-shaped plate can be disposed within the slide groove and reciprocate along the extension direction of the slide groove. The end of the first arc-shaped plate facing the bottom of the slide groove is the locking rope portion.

[0010] The first arc-shaped plate and the first through hole correspond to the same arc segment in the circumferential direction of the wheel body.

[0011] In some embodiments of the present invention, the bottom of the slide is stepped or gradually changing, or the bottom portion of the slide that contacts the first arc-shaped plate is stepped or gradually changing.

[0012] In some embodiments of the present invention, the side wall of the wheel body is further provided with a second through hole communicating with the slide groove. The second through hole is disposed opposite to the first through hole, and the second through hole is used to allow the gripper assembly of the rope clamping mechanism of the rope embroidery device to pass through.

[0013] In some embodiments of the present invention, the wheel body includes an upper circular plate, a body, and a lower circular plate arranged sequentially. The upper circular plate, the body, and the lower circular plate are integrally formed, or at least two of the body, the upper circular plate, and the lower circular plate are detachably connected.

[0014] The diameter of the lower circular plate is larger than the diameter of the main body. A notch is provided on the lower circular plate. The notch and the first through hole correspond to the same arc segment in the circumferential direction of the wheel body.

[0015] The main body is provided with the first and second through holes and the sliding groove.

[0016] In some embodiments of the present invention, the switching component further includes a second arc-shaped plate disposed opposite to the first arc-shaped plate. The second arc-shaped plate is adapted to the inner surface of the slide groove so that the second arc-shaped plate can be disposed within the slide groove and reciprocate along the extension direction of the slide groove. The second through hole and the second arc-shaped plate correspond to the same arc-shaped segment in the circumferential direction of the wheel body.

[0017] When the first arc-shaped plate is in either the first or second switching position, the second through hole allows the gripper assembly to pass through.

[0018] In some embodiments of the present invention, at least one of the first arc-shaped plate and the second arc-shaped plate is anti-rotationally engaged with the groove.

[0019] In some embodiments of the invention, the first through hole allows the gripper assembly to pass through.

[0020] In some embodiments of the present invention, an air blowing assembly is further included, wherein the air nozzle of the air blowing assembly faces the first through hole and the airflow direction of the air nozzle is perpendicular to the direction from the second through hole to the first through hole; or, the air nozzle of the air blowing assembly faces the second through hole and the airflow direction of the air nozzle is parallel to the direction from the second through hole to the first through hole.

[0021] According to an embodiment of the second aspect of the present invention, a rope embroidery device includes a rope clamping mechanism and a looping wheel mechanism of the rope embroidery device of the first aspect, wherein the gripper assembly of the rope clamping mechanism moves relative to the looping wheel assembly of the looping wheel mechanism to place a rope in the receiving portion of the looping wheel assembly.

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0050] like Figure 1-17 As shown, a loop-making wheel mechanism 20 of a rope embroidery device 100 provided according to the first aspect of the present invention includes a loop-making wheel assembly 21, which is provided with a rope-accommodating portion and a rope-locking portion.

[0051] The locking rope part moves relative to the receiving rope part and has a first switching position and a second switching position. When the locking rope part is in the first switching position, the rope can enter the receiving rope part; when the locking rope part is in the second switching position, the locking rope part locks the rope in the receiving rope part.

[0052] It should be noted that the beading wheel assembly 21 can be a single unit, with a rope-accommodating portion and a rope-locking portion. Alternatively, the beading wheel assembly 21 can be divided into two independent parts, one with a rope-accommodating portion and the other with a rope-locking portion. Or, the beading wheel assembly 21 can be divided into three independent parts, one with a rope-accommodating portion and another with a rope-locking portion. These are not all listed in this embodiment.

[0053] In practical applications, the rope embroidery device 100 also includes a rope clamping mechanism 30, which includes a gripper assembly 31.

[0054] When the locking section is in the first switching position, the gripper assembly 31 moves relative to the looping wheel mechanism 20. The gripper assembly 31 grips the rope and releases it into the rope receiving section. When the locking section is in the second switching position, it locks the rope into the rope receiving section. This allows the looping wheel assembly 21 to automatically thread the rope, avoiding manual threading, reducing the labor intensity of operators, and improving the efficiency of embroidery.

[0055] Therefore, in this embodiment, the ring-making wheel mechanism 20 is provided with a rope-accommodating part and a rope-locking part. The rope-locking part moves relative to the rope-accommodating part and has a first switching position and a second switching position, which helps the ring-making wheel assembly to cooperate with the claw assembly 31 of the rope-clamping mechanism 30, thereby realizing the automatic rope threading of the ring-making wheel assembly 21.

[0056] Preferably, the ring-forming wheel assembly 21 can be divided into two independent parts. The following embodiment illustrates this by showing that the ring-forming wheel assembly 21 includes a wheel body 211 and a switching element 212:

[0057] In some embodiments of the present invention, the wheel body 211 is provided with a rope-accommodating portion, and the switching member 212 is provided with a rope-locking portion. The switching member 212 reciprocates along the axial direction of the wheel body 211 and has a first switching position and a second switching position.

[0058] In the first embodiment, as Figure 9-11 As shown, the wheel body 211 can be cylindrical, and its axis is arranged vertically. The wheel body 211 has a groove 203, which is recessed from the end face of the wheel body 211. A first through hole 201 is provided on the side wall of the wheel body 211, communicating with the groove 203. The first through hole 201 allows the gripper assembly 31 to pass through. The combination formed by the first through hole 201 and the groove 203 can be understood as the aforementioned rope-accommodating portion.

[0059] The switching component 212 includes a first arc-shaped plate 2121, which is adapted to the inner surface of the slide groove 203 so that the first arc-shaped plate 2121 is disposed within the slide groove 203 and reciprocates vertically within the slide groove 203. The lower end 21211 of the first arc-shaped plate 2121 is configured as the aforementioned rope locking part. The first arc-shaped plate 2121 and the first through hole 201 correspond to the same arc-shaped segment in the circumferential direction of the wheel body 211.

[0060] When the first arc-shaped plate 2121 of the switching component 212 is in the first switching position, such as Figure 12 , 14 As shown, the lower end 21211 of the first arc-shaped plate 2121 is spaced apart from the bottom 2031 of the slide groove 203, and at the current moment, the gripper assembly 31 can pass through the first through hole 201 to place the rope at the bottom 2031 of the slide groove 203. When the first arc-shaped plate 2121 of the switching member 212 switches from the first switching position to the second switching position, as shown... Figure 13 , 15 As shown, the lower end 21211 of the first arc plate 2121 abuts against the bottom 2031 of the groove 203 to lock the rope between the first arc plate 2121 of the switching member 212 and the bottom 2031 of the groove 203 of the wheel body 211.

[0061] In the second embodiment, the wheel 211 is generally cylindrical, and its axis is arranged vertically. A first boss extends radially outward from the bottom surface of the wheel 211, and a first blind hole is formed on the sidewall of the wheel 211 near the first boss, allowing the gripper assembly 31 to pass through. The combination of the first blind hole and the first boss can be understood as the aforementioned rope-accommodating portion.

[0062] The switching element 212 can be an annular component, and it is sleeved on the side wall of the wheel body 211. The switching element 212 reciprocates along the axis of the wheel body 211. The lower end of the switching element 212 is configured as the aforementioned rope locking part.

[0063] When the switching element 212 is in the first switching position, its lower end is spaced apart from the first protrusion of the wheel body 211, and the lower end of the switching element 212 does not obstruct the first blind hole, so that the gripper assembly 31 can pass through the first blind hole and place the rope in the first blind hole. When the lower end of the switching element 212 switches from the first switching position to the second switching position, the lower end of the switching element 212 abuts against the first protrusion of the wheel body 211 to lock the rope between the lower end of the switching element 212 and the first protrusion of the wheel body 211.

[0064] Of course, it is understood that the wheel body 211 and the switching component 212 can be other suitable structures in addition to the structures in the first and second embodiments described above, which will not be listed one by one in this embodiment.

[0065] In some embodiments of the present invention, the wheel body 211 is provided with a rope-accommodating portion, and the switching member 212 is provided with a rope-locking portion. The switching member 212 reciprocates about the axis of the wheel body 211 to have a first switching position and a second switching position.

[0066] In the third embodiment, the wheel 211 may be cylindrical, with its axis arranged vertically. The wheel 211 has a groove formed by recessing from its end face. A second through hole is provided on the side wall of the wheel 211, communicating with the groove. The second through hole allows the gripper assembly 31 to pass through. The second through hole is configured to accommodate the rope portion described above.

[0067] The switching element 212 may be an annular shape, and it is adapted to fit into a groove so that it is disposed within the groove and can reciprocate about the axis of the wheel 211. A third through hole extending radially through the side wall of the switching element 212 is provided. This third through hole allows the gripper assembly 31 to pass through. This third through hole is configured as the aforementioned rope locking portion.

[0068] When the switching element 212 is in the first switching position, the third through hole of the switching element 212 corresponds to the second through hole of the wheel body 211, so that the gripper assembly 31 can pass through the second through hole to the third through hole, and the gripper assembly 31 releases the rope into the third through hole and the second through hole. When the switching element 212 switches from the first switching position to the second switching position, the rope is locked between the switching element 212 and the wheel body 211 through the damping engagement between the switching element 212 and the groove.

[0069] Of course, it is understood that the wheel body 211 and the switching component 212 can be other suitable structures besides the structure in the third embodiment described above, which will not be listed one by one in this embodiment.

[0070] Considering the manufacturing difficulty and processing cost of the wheel body 211 and the switching component 212, as well as the stability of the rope locked between the switching component 212 and the wheel body 211, the wheel body 211 and the switching component 212 in the first embodiment are preferred.

[0071] The following embodiments use the wheel 211 and switching component 212 in the first embodiment as examples for illustration:

[0072] In some embodiments of the present invention, the bottom 301 of the slide groove 203 is stepped, or the bottom portion of the slide groove 203 that contacts the first arc plate 2121 is stepped.

[0073] like Figure 9 , Figure 11 As shown, the bottom 2031 of the slide 203 has a circular hollow area, so that the bottom 2031 of the slide 203 is in a two-stage stepped shape, including a first upper step and a first lower step arranged vertically. Correspondingly, the lower end 21211 of the first arc plate 2121 of the switching member 212 is in a two-stage stepped shape, including a second upper step and a second lower step arranged vertically.

[0074] The second upper step is fitted with a clearance between it and the first upper step. The gap between the second upper step and the first upper step is slightly larger than the diameter of the rope to prevent the rope from getting stuck between the mating second upper step and the first upper step, which would affect the switching component 212 from disengaging from the bottom 2031 of the slide groove 203. The second lower step is fitted with a clearance between it and the first lower step in the same way, and will not be described in detail.

[0075] In addition, the bottom 2031 of the slide groove 203 is in the shape of two steps, which increases the length of the rope in contact with the bottom 2031 of the slide groove 203, so that a longer rope is pressed between the bottom 2031 of the slide groove 203 and the lower end 21211 of the first arc plate 2121, thereby helping to improve the stability of the locking rope of the wheel body 211 and the switching member 212.

[0076] Of course, it is understandable that in some embodiments, the bottom 2031 of the slide 203 has a circular hollow area so that the cross-section of the bottom 2031 of the slide 203 gradually changes along the axial direction of the wheel body 211. For example, the bottom 2031 of the slide 203 is tapered, and the cross-section of the bottom 2031 of the slide 203 gradually decreases from top to bottom; correspondingly, the lower end 21211 of the first arc-shaped plate 2121 of the switching member 212 is approximately conical, and the cross-section of the lower end 21211 of the first arc-shaped plate 2121 gradually decreases from top to bottom. This embodiment does not list them all.

[0077] In practical applications, such as Figure 1 , Figure 2 As shown, the rope embroidery device 100 also includes a rope embroidery support assembly 10, which is connected to the head housing 200 of the computer embroidery machine.

[0078] like Figures 3-5 As shown, the rope embroidery support assembly 10 includes a first telescopic mechanism 11 and a first sliding assembly 12. The first telescopic mechanism 11 can be an electric push rod or a pneumatic push rod. The first sliding assembly 12 includes a first slide rail 121 and a first sliding plate 122 that are slidably engaged. The first slide rail 121 is arranged in a vertical direction. The first telescopic mechanism 11 drives the first sliding plate 122 to slide along the first slide rail 121, thereby causing the first sliding plate 122 to slide up and down in a vertical direction.

[0079] The ring-shaped wheel mechanism 20 is connected to the first slide plate 122. Specifically:

[0080] like Figure 6 As shown, the ring-turning wheel mechanism 20 includes a ring-turning wheel assembly 21, a wheel support frame 22, a switching drive component 23, a shift fork 24, a wheel support component 25, a drive pulley 271, and a belt 272. Figure 9 As shown, the ring wheel assembly 21 includes a wheel body 211 and a switching component 212. The switching component 212 includes an annular ring 2123 and a first arc-shaped plate 2121. The first arc-shaped plate 2121 is arranged vertically and connected to the annular ring 2123. The annular ring 2123 has an annular groove, which is engaged with the shift fork 24.

[0081] like Figure 9 As shown, the wheel body 211 includes an upper circular plate 2112, a body 2111, and a lower circular plate 2113 arranged sequentially from top to bottom. The upper circular plate 2112 and the body 2111 are integrally formed. The combination of the upper circular plate 2112 and the body 2111 is detachably connected to the lower circular plate 2113, for example, by fasteners. This reduces processing difficulty and production costs. Of course, it is understood that in some embodiments, the upper circular plate 2112, the body 2111, and the lower circular plate 2113 are integrally formed.

[0082] The diameter of the lower circular plate 2113 is larger than the diameter of the body 2111. The bottom 2031 of the aforementioned groove 203 is formed on the lower circular plate 2113. The aforementioned first through hole 201 is formed on the body 2111. Engaging teeth are formed on the upper circular plate 2112.

[0083] like Figure 6 As shown, the wheel support frame 22 and the switching drive component 23 are connected to the first slide plate 122. The wheel support component 25 is connected to the wheel support frame 22, and the wheel 211 is sleeved on the wheel support component 25, with a bearing 26 between them. The shift fork 24 is connected to the switching drive component 23, and the shift fork 24 drives the switching component 212 to reciprocate linearly along the axis of the wheel 211. The belt 272 winds around the meshing teeth and the drive pulley 271, thereby driving the wheel 211 and the switching component 212 in the second switching position to rotate as a whole. That is, the loop wheel assembly 21 rotates to perform rope embroidery.

[0084] Furthermore, at least one of the first arc-shaped plate 2121 and the second arc-shaped plate 2122 is engaged with the slide groove 203 to prevent rotation.

[0085] like Figure 9 As shown, the slide groove 203 includes a first part and a second part. The first part matches the first arc-shaped plate 2121, and the second part matches the second arc-shaped plate 2122. When the first arc-shaped plate 2121 is in the second switching position, both the first arc-shaped plate 2121 and the second arc-shaped plate 2122 are in anti-rotation engagement with the slide groove 203. The drive pulley 271 rotates, and through the engagement of the belt 272 with the meshing teeth on the wheel body 211, the wheel body 211 rotates. Since both the first arc-shaped plate 2121 and the second arc-shaped plate 2122 are in anti-rotation engagement with the slide groove 203, the wheel body 211 and the switching component 212 rotate together, and there is no relative movement between them. That is, the ring wheel assembly 21 rotates to perform rope embroidery.

[0086] In some embodiments of the present invention, a second through hole 202 communicating with the slide groove 203 is also provided on the side wall of the wheel body 211. The second through hole 202 is disposed opposite to the first through hole 201. The second through hole 202 is used to allow the gripper assembly 31 of the rope clamping mechanism 30 of the rope embroidery device 100 to pass through.

[0087] like Figure 10 As shown, the switching component 212 includes an annular ring 2123, a first arc-shaped plate 2121, and a second arc-shaped plate 2122, the length of the second arc-shaped plate 2122 being less than the length of the first arc-shaped plate 2121. The first arc-shaped plate 2121 and the second arc-shaped plate 2122 are arranged opposite to each other and are both connected to the annular ring 2123.

[0088] The side wall of the wheel body 211 is provided with a second through hole 202 and a first through hole 201 communicating with the slide groove 203. The second through hole 202 and the first through hole 201 are arranged opposite to each other. The second through hole 202 and the second arc-shaped plate 2122 correspond to the same arc segment in the circumferential direction of the wheel body 211, and the first through hole 201 and the first arc-shaped plate 2121 correspond to the same arc segment in the circumferential direction of the wheel body 211. With this arrangement, the combination of the two arc-shaped plates can suppress the swaying of the switching member 212 in the circumferential direction of the wheel body 211, so that the first arc-shaped plate 2121 only has vertical movement.

[0089] In addition, it should be noted that, such as Figures 12-15 As shown, when the first arc plate 2121 is in the first switching position or the second switching position, the second arc plate 2122 does not affect the gripper assembly 31 passing through the second through hole 202.

[0090] like Figure 16a As shown in Figure -d, the process of the gripper assembly 31 engaging with the wheel body 211 of the beading wheel assembly 21 is illustrated. When the gripper assembly 31 is in position C33, the rope may be U-shaped and located within the wheel body 211. Consequently, when the switching element 212 is in the second switching position, the switching element 212 may not be able to hold the rope firmly, or the switching element 212 may not effectively hold the rope, resulting in the rope not being stably locked between the wheel body 211 and the switching element 212.

[0091] Based on this, a notch 21131 is provided on the lower circular plate 2113. The notch 21131 and the first through hole 201 correspond to the same arc segment in the circumferential direction of the wheel body 211. When the gripper assembly 31 moves from position C33 to position C34, the end of the rope can spring back from the notch 21131, and the rope can be in a straight position inside the wheel body 211, such as... Figure 17 As shown, the probability of the switching component 212 pressing down on the rope is greatly increased.

[0092] Furthermore, such as Figure 7 and Figure 8 As shown, the ring-forming wheel mechanism 20 also includes an air-blowing assembly 28, which is connected to the wheel support frame 22. The air nozzle of the air-blowing assembly 28 faces the first through hole 201, and the airflow direction of the air nozzle is ( Figure 8 The direction from the dashed arrow (in the middle) to the first through hole 201 (the direction from the second through hole 202 to the first through hole 201) Figure 8 The angle between the solid arrow and the arrowhead is α = 90°.

[0093] For example, such as Figure 16c As shown, when the gripper assembly 31 is at position C33, the rope may be in a U-shape within the reel 211. Airflow from the nozzle causes the rope end to spring back, allowing the rope to remain straight within the reel 211, as... Figure 17As shown, this helps the switch 212 to hold the rope down.

[0094] Of course, it is understandable that the nozzle of the air blowing assembly 28 is oriented toward the second through hole 202, and the airflow direction of the nozzle is the same as the direction from the second through hole 202 to the first through hole 201.
