Description

Technical Field

[0001] This invention belongs to the technical field of embroidery equipment, specifically relating to an automatic bobbin wrapping machine and an automatic bobbin assembly machine. Background Technology

[0002] Currently, some automatic bobbin winding and bobbin case assembly machines have appeared on the market, and these machines are equipped with storage tray racks for storing bobbin case cores. Referring to Chinese utility model patent CN214244850 U, a multi-disc assembly for an automatic bobbin case core winding and unwinding integrated device is disclosed. This assembly includes a support, a disc body, a drive device, and a storage tray for storing bobbin case cores. The disc body is detachably equipped with at least two or more storage trays. The disc body moves on the support. The drive device includes a main drive and secondary drives. The main drive moves the disc body to the position of the mechanical gripper; the secondary drives rotate the storage trays circumferentially around the center and align them with the mechanical gripper. The disc body has multiple secondary drives, with the number of secondary drives corresponding one-to-one with the number of storage trays. Each secondary drive individually controls the rotation of its corresponding storage tray. Both the main drive and secondary drives are motors. Because the number of storage trays installed on the disc body is relatively large (e.g., four in this patent), and sometimes even more storage trays are used, the number of motors needs to be increased, increasing costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a storage tray frame device and its automatic winding bobbin and automatic assembly shuttle shell machine, which solves the problem that each storage tray requires a motor to drive its rotation, resulting in a large number of motors and excessive cost.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: Preferred, a storage tray rack device is provided, comprising: A storage tray mounting frame, wherein a plurality of storage tray rotation positioning components are evenly distributed along the circumferential direction, and the storage tray rotation positioning components include a storage tray positioning mounting base for positioning the storage tray and a storage tray rotation drive shaft connected to the storage tray positioning mounting base; A first motor is used to drive the storage tray mounting frame to rotate. The second motor is connected to the storage tray rotation drive shaft of one of the storage tray rotation positioning components, thereby driving the storage tray connected to the storage tray rotation positioning component to rotate accordingly. A clutch component is used to connect or disconnect the second motor from the rotating drive shaft of the rotating positioning component of the storage tray.

[0005] Preferably, the clutch component includes a clutch slide rail that is slidably connected to the second motor. The clutch slide rail is used to guide the second motor to move linearly, thereby realizing the connection or separation with the rotating positioning component of the storage tray.

[0006] Preferably, the clutch component further includes a third motor and a clutch transmission assembly, wherein the third motor drives the clutch transmission assembly, and the clutch transmission assembly drives the second motor to move linearly.

[0007] Preferably, the storage tray rotation drive shaft passes through the storage tray mounting bracket, the first end of the storage tray rotation drive shaft is connected to the storage tray positioning mounting seat, the second end of the storage tray rotation drive shaft is provided with a shaft hole, and the output shaft of the second motor is connected to the shaft hole.

[0008] Preferably, the second end of the rotating drive shaft of the storage tray is provided with a second pin hole on the radially outer side of the shaft hole, and the output shaft of the second motor is provided with a second positioning pin on the radially outer side, and the second positioning pin is connected to the second pin hole.

[0009] Preferably, a positioning plate is fixed radially outward of the output shaft of the second motor, and the second positioning pin is disposed on the positioning plate.

[0010] Preferably, the storage tray rotation positioning component further includes a clutch disc slidably connected to the second end of the storage tray rotation drive shaft, and the second motor is connected to a clutch top shaft, which is used to drive the clutch disc to slide toward the second end of the storage tray rotation drive shaft so that the second end of the storage tray rotation drive shaft is exposed.

[0011] Preferably, the rotating positioning component of the storage tray further includes a clutch spring, a guide rod, and a fixed plate. The fixed plate is fixed to the second end of the storage tray mounting frame. One end of the guide rod is fixed to the fixed plate, and the other end is slidably connected to the clutch plate. The clutch spring is sleeved on the guide rod, and one end abuts against the fixed plate, and the other end abuts against the clutch plate.

[0012] Preferably, the storage tray positioning mounting base includes a base body with a central through hole and a first positioning pin located at the eccentric part of the first end of the base body, wherein the storage tray rotation drive shaft passes through the central through hole on the base body, and the first positioning pin is connected to the first pin hole on the storage tray.

[0013] In addition, the present invention also provides an automatic winding bobbin and an automatic assembly shuttle shell machine, including the aforementioned storage tray frame device.

[0014] The present invention adopts the above technical solution and has the following technical effects: The storage tray mounting frame has several storage tray rotation positioning components evenly distributed along the circumference. Each storage tray rotation positioning component includes a storage tray positioning mounting base for positioning the storage tray and a storage tray rotation drive shaft connected to the storage tray. A second motor is connected to the storage tray rotation drive shaft of one of the storage tray rotation positioning components, thereby driving the storage tray to rotate accordingly. That is, only one second motor is set to drive all the storage trays on the storage tray mounting frame to rotate, so that it is not necessary to set a motor to drive the rotation of each storage tray. Compared with the prior art, the number of motors can be saved, which greatly reduces the cost.

[0015] In addition, the second motor is fixed in relative position, and the first motor is used to drive the storage tray mounting frame to rotate. Each time the storage tray mounting frame rotates one station, that is, the distance between the axes of two adjacent storage trays, the axis of another storage tray can be rotated to the same position as the axis of the second motor, thereby realizing the relative position change between the second motor and multiple storage trays.

[0016] When the second motor drives one of the storage trays on the storage tray mounting bracket, the second motor needs to be connected to the storage tray rotation drive shaft of the storage tray rotation positioning component corresponding to that storage tray; when it is necessary to drive other storage trays, the second motor needs to be separated from the storage tray rotation drive shaft of the storage tray rotation positioning component corresponding to that storage tray. Therefore, a clutch component is provided to realize the connection or separation of the second motor from the storage tray rotation drive shaft of the storage tray rotation positioning component.

[0017] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0025] Automatic bobbin winding and automatic shuttle assembly machines include, for example Figures 1 to 6 The storage tray rack device shown has the same function as the patent cited in the background art. To address the problem in existing technologies where each storage tray requires a separate motor for rotation, resulting in a large number of motors and high cost, the storage tray rack device provided in this embodiment requires only one storage tray drive motor to drive all storage trays to rotate. It includes: A storage tray mounting frame 114 has a plurality of storage tray rotation positioning components evenly distributed along the circumference of the frame. Each storage tray rotation positioning component is used to position the storage tray 113. Each component includes a storage tray positioning mounting base 124 and a storage tray rotation drive shaft 122 connected to the mounting base 124. The mounting base 124 and the rotation drive shaft 122 are detachably connected to the storage tray 113. The rotation drive shaft 122 cooperates with the mounting base 124 to drive the storage tray 113 to rotate. The first motor 115 is used to drive the storage tray mounting frame 114 to rotate. The second motor 118 is connected to one of the storage tray rotation positioning components, thereby driving the storage tray connected to the storage tray rotation positioning component to rotate accordingly. A clutch component is used to connect or disconnect the second motor 118 from one of the storage tray rotation positioning components.

[0026] That is, the second motor 118 is connected to one of the storage tray rotation positioning components through the clutch component, while the other storage tray rotation positioning components are separated from the second motor 118.

[0027] In some embodiments, the clutch component includes a clutch slide rail 117 slidably connected to the second motor 118, a third motor 116, and a clutch transmission assembly. The clutch slide rail 117 guides the second motor 118 to move linearly, thereby enabling connection or separation from the rotating positioning component of the storage tray. The third motor 116 drives the clutch transmission assembly, which in turn drives the second motor 118 to move linearly.

[0028] It is understood that the clutch transmission assembly can be a lead screw and nut assembly, wherein the nut is connected to the second motor and the lead screw is connected to the third motor 116. Of course, it can also be a gear and rack assembly, or any other assembly that can convert the rotational motion of the third motor 116 into the linear motion of the second motor.

[0029] To facilitate the connection of both ends of the storage tray rotation drive shaft 122 to the storage tray positioning mounting base 124 and the second motor 118, the storage tray rotation drive shaft 122 passes through the storage tray mounting frame 114. The storage tray positioning mounting base 124 is connected to the first end of the storage tray rotation drive shaft, and the second end of the storage tray rotation drive shaft is connected to the output shaft of the second motor.

[0030] Specifically, the second end of the storage tray rotary drive shaft 122 is provided with a shaft hole 1221, and the output shaft 120 of the second motor is connected to the shaft hole 1221. The second end of the storage tray rotary drive shaft 122 has a second pin hole 1222 radially outward from the shaft hole, and a second positioning pin 119 is provided radially outward from the output shaft of the second motor, connecting to the second pin hole 1222. A positioning plate 1191 is fixed radially outward from the output shaft of the second motor, and the second positioning pin 119 is located on the positioning plate 1191. This design not only enables the output shaft 120 of the second motor to drive the storage tray rotary drive shaft 122 to rotate, but also ensures the relative angle between the output shaft 120 of the second motor and the storage tray rotary drive shaft 122.

[0031] In some embodiments, the storage tray positioning mounting base 124 includes a base body 1241 with a central through hole 1244 and a first positioning pin 1242 located at an eccentric portion of the first end of the base body, wherein the storage tray rotation drive shaft 122 passes through the central through hole 1244 on the base body. A clamp 1243 is provided at the second end of the base body 1241 and is fixedly connected to the storage tray rotation drive shaft 122, so that the storage tray rotation drive shaft 122 can drive the storage tray positioning mounting base 124 to rotate together.

[0032] To enable a detachable connection between the storage tray positioning mounting base 124 and the storage tray 113, a latch is provided between the storage tray 113 and the storage tray positioning mounting base 124 to axially lock the storage tray 113 and the storage tray positioning mounting base 124. The storage tray 113 has a drive shaft hole at its center that engages with the storage tray rotation drive shaft 122. A first positioning pin 1242 is located near the edge of the base, and a first pin hole is located radially outside the drive shaft hole. During docking, the first positioning pin 1242 aligns with the first pin hole. Simultaneously, when the first positioning pin 1242 connects with the first pin hole on the storage tray, the storage tray rotation drive shaft 122 can drive the storage tray 113 to rotate.

[0033] When installing the storage tray, align the drive shaft hole on the storage tray with the storage tray rotation drive shaft 122, and then apply appropriate force to push the storage tray axially. After the storage tray is axially moved into place, the latch will engage and fix the storage tray with the storage tray positioning mounting base 124. In this way, the storage tray is fixed on the storage tray positioning mounting base 124, ensuring that the storage tray is reliably fixed after replacement and will not fall off during operation. When disassembling the storage tray, release the latch, pull the storage tray outward, and separate the drive shaft hole on the storage tray from the storage tray rotation drive shaft 122. This also facilitates the replacement of the storage tray.

[0034] The specific connection structure between the storage tray rotation drive shaft 122 and the storage tray positioning mounting base 124 and the storage tray 113, including the locking structure and transmission structure and principle, can be found in the applicant's prior patent application, such as Chinese invention patent application with publication number CN119593151A.

[0035] Furthermore, the rotating positioning component of the storage tray also includes a clutch disc 123, a clutch spring 127, a guide rod 126, and a fixed disc 125 slidably connected to the second end of the storage tray rotating drive shaft 122. The second motor 118 is connected to a clutch top shaft 121, and multiple clutch top shafts 121 can be distributed circumferentially, for example, three. The shaft ends of the clutch top shafts 121 act axially with the clutch disc 123. The fixed disc 125 is fixed to the second end of the storage tray mounting bracket. One end of the guide rod 126 is fixed to the fixed disc, and the other end is slidably connected to the clutch disc. The guide rod 126 can be a screw, with one end passing through the clutch disc and threadedly connected to the fixed disc, while the screw head at the other end has a limiting function that cooperates with the clutch disc. The clutch spring 127 is sleeved on the guide rod, with one end abutting against the fixed disc 125 and the other end abutting against the clutch disc 123.

[0036] The second end of the storage tray rotary drive shaft 122 and the inner hole of the clutch disc 123 are both flat rectangular structures with a cross-section consisting of two parallel straight edges and two outwardly convex arc edges. This allows for axial sliding between the second end of the storage tray rotary drive shaft and the inner hole of the clutch disc 123, but not circumferential rotation. Under normal conditions, the clutch disc 123 and the second end of the storage tray rotary drive shaft are fixed in their axial relative positions under the action of the clutch spring 127, thus preventing the storage tray rotary drive shaft from rotating. When the clutch mechanism is engaged, the second motor moves towards the second end of the storage tray rotary drive shaft, causing the clutch top shaft to engage with the clutch disc, which then moves axially towards the first side. The clutch disc and the second end of the storage tray rotary drive shaft are axially offset from each other, allowing the output shaft 120 of the second motor 118 to connect with the shaft hole 1221 and the second positioning pin 119 to connect with the second pin hole 1222. The output shaft 120 of the second motor 118 can drive the storage tray rotary drive shaft 122 to rotate, thereby driving the storage tray 113 to rotate. When the clutch mechanism is engaged, causing the second motor 118 to move away from the storage tray rotary drive shaft, the clutch disc 123 moves axially towards the second side under the action of the clutch spring 127, achieving a reset.

[0037] The first motor 115 drives the storage tray mounting frame 114 to rotate. Each rotation, corresponding to the distance between the axes of two adjacent storage trays, causes the axis of the other storage tray to rotate to a position concentric with the axis of the second motor 118. The second motor 118 is the storage tray drive motor, used to drive the storage trays to rotate. The third motor 116 is a clutch motor. After the bobbin winding on one storage tray is completed, the third motor 116 controls the second motor 118 to disengage from the storage tray rotation positioning component. The first motor 115 then controls the storage tray mounting frame 114 to rotate, rotating the axis of the other storage tray to a position concentric with the axis of the second motor 118. The third motor 116 then controls the second motor 118 to disengage from the storage tray rotation positioning component, thereby driving the other storage tray to rotate. This cycle repeats, completing the operation of the storage trays on the storage tray frame. Since only one second motor is used to drive all the storage trays on the storage tray mounting frame to rotate, it is not necessary to set up a motor to drive the rotation of each storage tray. Compared with the existing technology, this can save the number of motors and greatly reduce costs.

[0038] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art should understand that the invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
