Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a shuttle rotating and winding device. Background Technology

[0002] Industrial sewing machines are designed for the large-scale production of sewn workpieces in factories and other industrial sectors. The rotary hook of an industrial sewing machine contains a bobbin, which consists of a bobbin case and a bobbin with thread wound around it. Because the bobbin has a limited thread capacity, sewing must stop when the thread in the bobbin is exhausted so that the bobbin can be replaced with a fully wound bobbin. Current automatic winding machines first press the thread end onto the end face of the bobbin, then the bobbin slowly rotates and winds 5 to 6 turns of thread, ensuring that the thread winds with the rotation of the bobbin. However, existing automatic winding machines leave thread ends after winding, and cannot automatically guide the thread ends to the thread guide hole in the bobbin case. The drive structure for automatic winding only needs to achieve rotational motion, but guiding the thread ends is more difficult, requiring the simulation of various complex actions of manual thread guiding. Therefore, to achieve automatic winding and thread end guiding, multiple drive structures are needed. However, increasing the number of drive structures makes the structure more complex and occupies a larger volume, requiring careful space and positional arrangement. Therefore, designing a reliable and compact rotary winding device is particularly necessary. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] The device described in this application is used in conjunction with a shuttle; the two corresponding shuttle structures are introduced below. (Combined with...) Figure 1-4 As shown, the first type of shuttle 7 includes a bobbin case 71 and a bobbin 72. The bobbin 72 can be inserted into the bobbin case 71, and a positioning circular hole 721 is provided on the end face of the bobbin 72. The bobbin case 71 includes: a shuttle housing 711, a shuttle door cover plate 712, a shuttle door bottom plate 713, and a bobbin skin 714. The shuttle door cover plate 712 and the shuttle door bottom plate 713 are installed on the top of the shuttle housing 711, and the bottom of the shuttle housing 711 has a flat hole 7111, through which the bobbin 72 is inserted into the bobbin case 71. The shuttle door bottom plate 713 is provided with a shuttle door bottom plate positioning hook 7131. The shuttle housing 711 includes: a thread passage hole 715, a thread pull groove 716, a needle drop hole 717, a positioning notch 718, and a bobbin shaft 719. The hook-shaped tip of the bobbin skin 714 corresponds to the thread passage hole 715 and divides the thread passage hole 715 into a first section 715a and a second section 715b. The bobbin 719 can be inserted into the winding shaft 722 of the bobbin 72, and a core hole 7191 is provided in the middle of the bobbin 719. When the shuttle door cover 712 is opened to the limit position, the shuttle door bottom plate 713 cannot pop out, and the shuttle door bottom plate positioning hook 7131 of the shuttle door bottom plate 713 can hold the bobbin 72 to prevent it from falling out. After the shuttle door cover 712 is flattened, the shuttle door bottom plate 713 can pop out to engage the mandrel groove of the positioning mandrel inside the rotary hook.

[0039] Combination Figure 5-7 As shown, the difference between the second type of shuttle 7 and the first type of shuttle 7 is that its bobbin sleeve 71 also includes a thread guide spring 720 mounted on the shuttle case 711.

[0040] This application applies to the above two types of bobbin cases 71, such as: C28-high-speed small oblique bobbin case, C29-Sunstar 380 bobbin case, C30-flatbed bobbin case, C32-large embroidery bobbin case, C34-2010 bobbin case, C40-3 times large bobbin case, C07-761 buttonhole bobbin case, C03-DY bobbin case, C04-246 bobbin case, and other bobbin case models.

[0041] A shuttle-rotating winding device, combined with Figures 8-15 As shown, it includes: a shuttle drive component that drives the shuttle 7 to rotate and slide along the rotation axis, and a winding knife drive component that drives the winding knife 121 to rotate around the shuttle 7.

[0042] The shuttle drive component includes: a winding station disk 111 for cooperating with the bobbin 72, a winding spindle 112 with a first mounting cavity at one end facing the shuttle 7, a sliding assembly coaxially fixed to the winding spindle 112, a reset elastic element 115 installed in the first mounting cavity, and a winding spindle driver 116 for driving the winding spindle 112 to rotate; the sliding assembly includes a winding mandrel 114 and a winding sleeve 113, the winding mandrel 114 and the winding sleeve 113 are coaxially arranged and connected in profile, one end of the winding mandrel 114 passes through the first mounting cavity and is connected to the reset elastic element 115, and the other end passes through the winding sleeve 113 and is coaxially fixed to the winding station disk 111, the reset elastic element 115 has the tendency to prevent the winding mandrel 114 from sliding along the axis of rotation;

[0043] The winding knife driving component includes a winding sleeve 128 coaxially arranged with the winding core 114 and a winding knife rotation driver 122 that drives the winding sleeve 128 to rotate. The winding sleeve 128 drives the winding knife 121 to rotate.

[0044] This application uses a winding spindle driver 116 to drive the winding spindle 112 to rotate, thereby causing the sliding assembly to rotate synchronously. The winding sleeve 113 is coaxially connected to the winding spindle 112, and the winding mandrel 114 is shaped and connected to the winding sleeve 113. A reset elastic element 115 is used to reset the winding mandrel 114. The winding station disk 111 is connected to the winding mandrel 114 to cooperate with and support the shuttle 7. This satisfies both the high-speed rotation of the bobbin 72 for winding and ensures that the winding station disk 111 and the shuttle 7 can float along the rotation axis, allowing the shuttle 7 to move in coordination with the movement of the robotic arm of the automatic winding machine along the rotation axis. Furthermore, the winding knife rotation driver 122 drives the winding sleeve 128 to rotate, and the winding sleeve 128 drives the winding knife 121 to rotate around the shuttle 7. This application integrates three functions: bobbin rotation, winding knife rotation, and bobbin floating along the bobbin rotation axis. It can work with the robotic arm, blow gun, winding knife, and shift fork of an automatic winding machine to achieve automatic winding and thread lead-out. The structure of this application is simple, compact, and easy to assemble and adjust, and can meet the reliability requirements of automatic winding machine rotation winding.

[0045] Preferably, the sliding assembly adopts a ball spline, specifically a BLF flange-type ball spline. The ball spline enables smooth torque transmission and axial sliding, simplifying the structure, improving reliability, ensuring long-term rotational and sliding accuracy, and preventing wire jamming, breakage, and long-term damage to the robotic arm of the automatic winding machine caused by nutation during high-speed rotation of the winding station disc 111. It is understood that the sliding assembly can also use conventional surface connections, for example: the inner wall of the central hole of the winding sleeve 113 is provided with a winding spline, and the outer periphery of the winding mandrel 114 is provided with a winding spline groove that mates with the winding spline.

[0046] Specifically, the shuttle drive component also includes a shuttle drive mounting base 117, which has a second mounting cavity at its center. The second mounting cavity includes a first circular hole 1171, a second circular hole 1172, a third circular hole 1173, and a fourth circular hole 1174 connected in sequence. The diameter of the first circular hole 1171 matches the outer diameter of the winding knife bearing 1286, the diameter of the second circular hole 1172 matches the outer diameter of the winding knife bearing 1286, the diameter of the fourth circular hole 1174 matches the outer diameter of the winding spindle bearing 1287, and the diameter of the third circular hole 1173 is smaller than the diameter of the fourth circular hole 1174, smaller than the diameter of the second circular hole 1172, and matches the outer diameter of the winding spindle bearing 1287. This results in a first stepped surface 1175 being formed at the connection between the first circular hole 1171 and the second circular hole 1172, a second stepped surface 1176 being formed at the connection between the second circular hole 1172 and the third circular hole 1173, and a third stepped surface 1177 being formed at the connection between the fourth circular hole 1174 and the third circular hole 1173.

[0047] Specifically, the winding spindle 112 is integrally machined. The winding spindle 112 includes a connecting shaft section 1121, a first cylindrical section 1122, a second cylindrical section 1123, and a third cylindrical section 1124, with their outer diameters increasing sequentially. The outer diameter of the first cylindrical section 1122 matches the inner diameter of the winding spindle bearing 1287; the outer diameter of the second cylindrical section 1123 matches the outer diameter of the inner ring of the winding spindle bearing 1287; and the outer diameter of the third cylindrical section 1124 is larger than the diameter of the third circular hole 1173. A fourth stepped surface 1125 is formed at the connection between the first cylindrical section 1122 and the second cylindrical section 1123. During assembly, the winding spindle 112 is inserted into the first circular hole 1171 of the second mounting cavity, and the first cylindrical section 1122 enters and exits through the fourth circular hole 1174. The third cylindrical section 1124 abuts against the second stepped surface 1176 to prevent the winding spindle 112 from falling off, and facilitates the installation of the winding spindle bearing 1287 from the reverse direction. The first winding spindle bearing 1287 is fitted onto the first cylindrical section 1122 from the side of the connecting shaft section 1121 of the winding spindle 112, so that its inner ring abuts against the fourth stepped surface 1125 and its outer ring abuts against the third stepped surface 1177, thereby achieving positioning. A spacer 1126 is fitted on the first cylindrical section 1122, and the spacer 1126 abuts against the inner ring of the first winding spindle bearing 1287. The second winding spindle bearing 1287 is fitted onto the first cylindrical section 1122 from one side of the connecting shaft section 1121 of the winding spindle 112, with its inner ring abutting against the spacer 1126. A first groove is formed on the inner wall of the fourth circular hole 1174, and a retaining ring is installed in the first groove to abut against the outer ring of the second winding spindle bearing 1287. A second groove is formed on the outer wall of the first cylindrical section 1122, and a retaining ring is installed in the second groove to abut against the inner ring of the second winding spindle bearing 1287. This achieves a rotational connection between the winding spindle 112 and the shuttle drive mounting base 117.

[0048] Specifically, the first mounting cavity includes a fifth circular hole 1127, a sixth circular hole 1128, and a seventh circular hole 1129 with successively increasing diameters. The fifth circular hole 1127 is machined within the first cylindrical section 1122, the seventh circular hole 1129 is machined within the third cylindrical section 1124, and the sixth circular hole 1128 transitions from the first cylindrical section 1122 to the third cylindrical section 1124. The connection between the sixth circular hole 1128 and the seventh circular hole 1129 forms a fifth stepped surface 1120. A threaded hole is machined on the fifth stepped surface 1120. The flange-type winding sleeve 113 of the ball spline is installed within the portions of the sixth circular hole 1128 and the seventh circular hole 1129 via a first set of connecting screws. One end of the winding mandrel 114 of the ball spline passes through the fifth circular hole 1127.

[0049] Specifically, the winding spindle driver 116 is a stepper motor, and the output shaft of the winding spindle driver 116 is connected to the connecting shaft section 1121 via a coupling.

[0050] Preferably, the reset elastic element 115 is located between the end of the winding mandrel 114 that penetrates the first mounting cavity and the bottom wall of the first mounting cavity. When the robotic arm pushes the shuttle 7, the winding station disk 111 transmits force to the winding mandrel 114, causing it to slide into the first mounting cavity, and the winding mandrel 114 compresses the reset elastic element 115. When the robotic arm moves in the opposite direction, the elastic force of the reset elastic element 115 allows the winding mandrel 114 to slide out of the first mounting cavity, always maintaining the movement of the shuttle 7 along the rotation axis under the drive of the robotic arm and the winding station disk 111. In this embodiment, the reset elastic element 115 is a compression spring.

The positioning shaft 1113 is inserted into the core hole of the bobbin sleeve 71 to achieve the positioning of the center position of the bobbin 7. The axis is positioned by the carrier plate 1112 abutting against the end face of the bobbin 72. The protrusion 1114 is inserted into the positioning round hole 721 of the bobbin 72 so that the bobbin 72 can rotate with the carrier plate 1112.

[0054] Specifically, one end of the winding connecting shaft section 1111 is machined with an external thread, and the end of the winding mandrel 114 is machined with a corresponding threaded hole. The outer circumferential surface of the winding connecting shaft section 1111 is milled flat so that the winding connecting shaft section 1111 and the winding mandrel 114 are threadedly connected.

[0055] Preferably, the winding positioning shaft 1113 has a guide surface 1115 at the end away from the carrier plate 1112. The guide surface 1115 guides the shuttle 7 to the winding station plate 111. The guide surface 1115 can be a frustum or a spherical surface, etc.

[0056] Preferably, the winding sleeve 128 is located above the winding sleeve 113, and the winding sleeve 128 has a mandrel clearance through hole 1142 at its center to allow the winding mandrel 114 to slide. The winding knife rotary driver 122 adopts synchronous belt drive and includes: winding active synchronous pulley 1221, winding driven synchronous pulley 1222, winding synchronous belt 1223 and winding knife rotary motor 1224. The winding driven synchronous pulley 1222 is coaxially sleeved on the outer periphery of the winding sleeve 128. The winding synchronous belt 1223 connects the winding active synchronous pulley 1221 and the winding driven synchronous pulley 1222. The winding knife rotary motor 1224 drives the winding active synchronous pulley 1221 to rotate.

[0057] Preferably, a winding spindle bearing mounting sleeve 1281 is fixedly installed at one end of the winding sleeve 128 facing the winding sleeve 113. The winding spindle bearing mounting sleeve 1281 includes: a connecting circular plate 1282 fixed to the end of the winding sleeve 113, a cylindrical section 1283 fixed to the side of the connecting circular plate 1282 away from the winding sleeve 113, and a stepped section 1284 fixed to the side of the cylindrical section 1283 away from the winding sleeve 113. The connecting circular plate 1282 and the cylindrical section 1283 are also fixed. The third and fourth steps are coaxially arranged. The outer diameter of the cylindrical section 1283 is larger than the outer diameter of the winding sleeve 128, and the inner diameter is larger than the outer diameter of the winding mandrel 114. The inner diameter of the sixth step 1284 is equal to the inner diameter of the cylindrical section 1283, and the outer diameter is larger than the outer diameter of the cylindrical section 1283 to form the sixth step surface 1289. A bearing pressure plate 1285 is provided on the outer sleeve of the winding sleeve 128. The bearing pressure plate 1285 and the sixth step surface 1289 respectively press the two ends of the inner ring of the winding knife bearing 1286. The winding sleeve 128 and the winding main shaft bearing mounting sleeve 1281 are integrally machined.

[0058] Specifically, the winding knife bearing 1286 is installed in the first circular hole 1171, with its outer ring abutting against the first stepped surface 1175 and its inner ring abutting against the sixth stepped surface 1289. The winding driven synchronous pulley 1222 is coaxially sleeved on the winding sleeve 128, and its end face is fixed to the end face of the winding sleeve 128 away from the winding sleeve 113 by the fourth set of connecting screws.
