Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and more specifically, to a multi-station yarn loading trolley mechanism. Background Technology

[0002] In current textile production, a fixed yarn feeding mode of "one machine, one column" is commonly used, meaning each spinning machine is equipped with a fixed yarn feeding column. The limitation of this mode is that some spinning machines have a low doffing frequency (e.g., only once a day), resulting in the yarn feeding column being idle most of the time. For workshops with multiple spinning machines, a large number of yarn feeding columns need to be installed, which not only incurs huge equipment procurement costs but also occupies valuable workshop space, resulting in extremely low equipment utilization and high overall operating costs. Therefore, in view of this, this paper studies and improves the existing structure to provide a multi-station yarn feeding trolley mechanism, aiming to achieve a more practical purpose. Summary of the Invention

[0003] 1. Technical problems to be solved To address the problems existing in the prior art, the present invention aims to provide a multi-station yarn loading trolley mechanism. Through integrated multi-station design and automated movement function, it enables one device to perform yarn loading operations for multiple textile machines, thereby improving equipment utilization, reducing equipment procurement and space usage costs for enterprises, and effectively solving the problems of high equipment idle rate, large workshop space occupation, and high operating costs in the traditional "one machine, one column" fixed yarn loading mode.

[0004] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0005] A multi-station yarn loading trolley mechanism includes multiple supporting columns and multiple textile machinery devices. I-beam guide rails and conveying rails are fixedly connected between the tops of the supporting columns. A drive module is slidably connected to the I-beam guide rails. A multi-station yarn loading trolley frame is fixedly installed at the bottom of the drive module. A lifting mechanism is installed inside the multi-station yarn loading trolley frame. A tray is fixedly connected to the bottom of the multi-station yarn loading trolley frame. A yarn picking bracket is installed above the tray, with one end of the yarn picking bracket connected to the lifting mechanism on its outer side. A flipping frame is installed on the inner side of the other end of the yarn picking bracket. Multiple yarn bobbin hangers are installed at the bottom of the conveying rails. An anti-deviation mechanism is installed between the middle of the supporting columns and the multi-station yarn loading trolley frame.

[0006] Furthermore, the drive module includes a mounting frame and a servo motor fixedly mounted inside the mounting frame. Two front drive wheels and two rear drive wheels are rotatably connected to both ends of the mounting frame via rotating shafts. Both the front and rear drive wheels slide on the inner wall of the I-beam guide rail. A travel drive shaft is rotatably connected to the inner walls of both sides of the mounting frame and below the front drive wheels. The outer periphery of the travel drive shaft is connected to the output shaft of the servo motor via two spiral bevel gears. Both ends of the travel drive shaft and the rotating shaft located at the position of the front drive wheels extend outward and are fixedly connected to transmission gears, and the two transmission gears on the same side are meshed together.

[0007] Furthermore, the front drive wheel and the rear drive wheel, located on the same side, are connected by a sprocket and a chain drive.

[0008] Furthermore, a transverse bracket is fixedly connected to the side of the mounting frame near the textile machinery, and photoelectric sensor one and photoelectric sensor two are fixedly installed at both ends of the transverse bracket, respectively.

[0009] Furthermore, two guide wheels are fixedly installed at both ends of the mounting frame, and the guide wheels are slidably connected to the inner wall of the I-beam guide rail.

[0010] Furthermore, the lifting mechanism includes a second servo motor fixedly installed on the top of the multi-station yarn frame and a lower synchronous pulley rotatably installed at the bottom of the multi-station yarn frame. The output shaft of the second servo motor is connected to the upper synchronous pulley via a key. The lower synchronous pulley and the upper synchronous pulley are connected by a synchronous belt drive. A lifting bracket is fixedly connected to the outer periphery of the synchronous belt. One end of the lifting bracket extends to the outside of the multi-station yarn frame and is fixedly connected to one end of the yarn picking bracket.

[0011] Furthermore, the anti-deviation mechanism includes an anti-deviation guide groove fixed to the middle of the support column, an anti-deviation guide rod fixed to one end of the multi-station upper yarn frame, and a second guide wheel fixed to one side of the multi-station upper yarn frame. One end of the anti-deviation guide rod slides in the anti-deviation guide groove, and the second guide wheel slides at the bottom of the anti-deviation guide groove.

[0012] Furthermore, a photoelectric sensor three is fixedly installed at the other end of the yarn picking bracket via an L-shaped bracket, and a photoelectric sensor four is fixedly installed at the other end of the yarn picking bracket and below the flipping frame.

[0013] Furthermore, a proximity sensor is installed on the top of the pallet at the position of the lifting bracket, and an RFID reader, a proximity sensor, and a photoelectric sensor are installed on the bottom of the pallet near the textile machinery. An electronic tag is installed on the end of the textile machinery near the supporting column.

[0014] 3. Beneficial Effects Compared with the prior art, the advantages of this invention are: This solution uses a drive module to propel a multi-station yarn loading carriage stably along an I-beam guide rail. Combined with an anti-deviation mechanism, it effectively prevents deviation during operation, ensuring precise switching of working positions between multiple textile machines. Simultaneously, with the assistance of a flipping frame, the yarn packages on the textile machines are rotated 90° and fall onto the yarn picking bracket. Under the action of a lifting mechanism, the yarn picking bracket lifts the yarn packages, and with the cooperation of the conveyor rails and yarn hanging racks, fully automated and lossless transfer and loading of the yarn packages from the textile machines to the yarn hanging racks is achieved. The entire yarn loading process can be completed without manual intervention, significantly improving loading efficiency. Furthermore, the multiple yarn hanging racks enable multi-station yarn storage. The collaborative work of various sensors and RFID readers allows for real-time monitoring of the yarn picking position, yarn package status, and equipment operating parameters, enabling intelligent control and fault warnings, further ensuring production stability and reliability.

The two transmission gears 507 located on the same side are meshed together.

[0020] See Figure 6 The front drive wheel 503 and the rear drive wheel 504, located on the same side, are connected by a sprocket and a chain drive.

[0021] See Figure 6 A horizontal support 13 is fixedly connected to the side of the mounting frame 501 near the textile machinery equipment 2. Photoelectric sensor 14 and photoelectric sensor 2 are fixedly installed at both ends of the horizontal support 13, respectively.

[0023] See Figure 6 The lifting mechanism 7 includes a servo motor 701 fixedly installed on the top of the multi-station upper yarn frame 6, and a lower synchronous pulley 702 rotatably installed on the bottom of the multi-station upper yarn frame 6.

[0024] See Figure 4 The anti-deviation mechanism 12 includes an anti-deviation guide groove 1201 fixed in the middle of the support column 1, an anti-deviation guide rod 1202 fixed at one end of the multi-station upper yarn frame 6, and a guide wheel 1203 fixed on one side of the multi-station upper yarn frame 6.

[0025] See Figure 4A photoelectric sensor 17 is fixedly installed at the other end of the yarn picking bracket 9 via an L-shaped bracket, and a photoelectric sensor 18 is fixedly installed at the other end of the yarn picking bracket 9 below the flipping frame 10.

[0026] See Figure 2 and Figure 5 A proximity sensor 19 is installed on the top of the pallet 8 at the position of the lifting bracket 705. An RFID reader 20, a proximity sensor 21, and a photoelectric sensor 22 are installed on the bottom of the pallet 8 near the textile machinery equipment 2. An electronic tag 23 is installed on the end of the textile machinery equipment 2 near the support column 1.

[0027] Working principle: The operator issues commands through the control system. The multi-station yarn loading carriage 6 and its structure start from the standby position and travel along the I-beam guide rail 3 towards the target station. When the proximity sensor 21 at the bottom of the pallet 8 detects the sensing element at the target station, the multi-station yarn loading carriage 6 and its structure decelerate and come to a precise stop. At this time, the RFID reader 20 at the bottom of the pallet 8 reads the electronic tag 23 installed on the textile machinery equipment 2 to confirm the machine number and yarn type information.

[0028] After information confirmation, photoelectric sensor 22 at the bottom of tray 8 sends a "ready" light signal to textile machinery 2. Upon receiving the signal, the internal conveyor belt of textile machinery 2 starts, transporting the yarn package to the waiting position at the exit of textile machinery 2 and pausing. At the same time, photoelectric sensors 17 and 18 on the yarn picker 9 detect that there is no yarn package in the flipping frame 10, and proximity sensor 19 confirms that the yarn picker 9 has descended to the lowest yarn receiving position.

[0029] Subsequently, the belt conveyor of textile machine 2 starts again, and the yarn at the front end falls. Due to the height difference between the outlet of textile machine 2 and the flipping frame 10, the yarn falls into the flipping frame 10 under gravity and completes a 90° rotation under the guidance of the frame structure. Immediately afterwards, servo motor 701 starts, driving the yarn picking bracket 9 to rise smoothly and steadily lift the yarn. The yarn picking bracket 9 continues to rise. At this time, under the action of the conveying guide rail 4, when the photoelectric sensor 14 and photoelectric sensor 15 on the yarn picking bracket 11 read the coding plate on the yarn picking bracket 11 and confirm that the yarn picking bracket 11 is empty and has reached the preset position, the yarn picking bracket 9 stops rising. Then, the yarn picking bracket 11 passes through the middle of the yarn picking bracket 9, the yarn picking bracket 9 lowers slightly, and the yarn is naturally and accurately suspended on the yarn picking bracket 11, completing one yarn loading action.

[0030] The control system records the number of yarns loaded and repeats the above process until all the yarns in the spinning machine 2 are loaded. After completion, the multi-station yarn loading carriage 6 and other structures receive new instructions from the system and automatically drive to the next spinning machine 2 that needs yarn loading, or return to the standby position after all tasks are completed, realizing a one-to-many yarn loading function.
