Description

Technical Field

[0001] This invention belongs to the field of self-winding machine structure improvement technology, specifically relating to a self-winding device for automatically discharging perforated sand bar. Background Technology

[0002] Automatic winding machines are key equipment in the textile industry used to rewind bobbins into cones that meet the requirements of subsequent processes, playing a crucial role in the spinning production line. In actual production, perforated yarn bars (i.e., yarn winding mandrels or bobbins with central through holes) are widely used for yarn winding and unwinding.

[0003] According to the search, the existing patent number is: 202011582450.8. A self-winding machine that can automatically discharge perforated yarn bars. "When the sand yarn bars in the yarn bar groove of the yarn bar placement roller 2 have finished winding, the electric push rod A5 is started, which causes the top plate 3 to push the sand yarn bars upward, thereby causing the yarn bars to leave the yarn bar placement roller 2, thus facilitating the automatic discharge of sand yarn bars and reducing the workload of workers.

[0004] However, when the device pushes out the yarn bars, it pushes out multiple bars simultaneously. Since the automatic winding machine is generally equipped with multiple spindles, the yarn consumption rate of each yarn bar is not the same. When some yarn bars still have yarn on them, if they are pushed out directly, the yarn will be broken, which will affect the production quality. Furthermore, after the bar is ejected, there is a lack of lateral guidance measures, resulting in the ejected bar being placed haphazardly on the worktable, affecting subsequent recycling. At the same time, during the bar ejection and recycling process, there is a lack of recycling components, causing the bar to fall onto the worktable and become difficult to retrieve. The safety factor for recycling is low when the equipment is in operation, and if the machine is stopped for recycling, the production efficiency will be reduced.

[0005] Therefore, it is necessary to provide an automatic winding device for automatically discharging yarn bars that can automatically detect the yarn status of the yarn bar, independently control the discharge of empty yarn bars, and stably guide and convey them, so as to reduce the degree of manual intervention and improve the level of automation and production efficiency.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, this embodiment of the invention provides an automatic winding device for discharging perforated wire rods, specifically including a winding machine 1. A placement mechanism 2 for placing multiple wire rods is installed on the bottom platform of the winding machine 1. A feeding mechanism 3 for ejecting and unloading the multiple wire rods is installed on the placement mechanism 2. The placement mechanism 2 includes a placement table 201, which is installed at the bottom of the winding machine 1. Multiple columns 202 are vertically connected to the placement table 201. The installation of the placement table 201 enables the placement of multiple wire rods, and the cooperation of the multiple columns 202 achieves the positioning of the wire rods, preventing them from slipping off the placement table 201. In this embodiment, the placement platform 201 is a "door" shaped structure. The bottoms of multiple columns 202 are threaded to the top of the placement platform 201. The top of the columns 202 is chamfered to facilitate the provision of space for the subsequent installation of the electric push rod 302. This also reduces the weight of the placement platform 201 and facilitates the disassembly and maintenance of the columns 202 and the placement platform 201. The operation is convenient. When the wire rod is inserted into the outside of the column 202, it plays a guiding role and prevents the wire rod from being worn against the inside.

[0022] Please see Figure 2 , Figure 4 and Figure 5As shown, the top-feeding mechanism 3 specifically includes a top plate 301. Multiple top plates 301 (three in this embodiment) are provided on the placement platform 201. These multiple top plates 301 are slidably connected to multiple columns 202 via guide holes 303. Multiple sets of driving components (the same number as the top plates 301) are installed at the bottom of the placement platform 201 to control the sliding of the multiple top plates 301. Through the multiple top plates 301, when the bar is fitted onto the column 202, the bottom of the bar is placed on top of the top plate 301. With the opening of the guide holes 303 and the cooperation of the multiple sets of driving components, the sliding of the multiple top plates 301 is controlled, facilitating the ejection of the bar from the column 202 and realizing the bar unloading operation.

[0023] Please see Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the driving component is an electric push rod 302. Two electric push rods 302 form a group, and the bottom output shafts of the two electric push rods 302 extend to the outer side of the top of the placement platform 201 and are connected to both ends of the bottom of the top plate 301. The output shafts of the electric push rods 302 are slidably connected to the top of the placement platform 201. The top plate 301 has an irregular shape with a circular center and extended ends. Through the installation of the electric push rods 302, under the drive of an external controller, the electric push rods 302 drive the top plate 301 to slide, thereby ejecting the wire rods after the wire feeding is completed. At the same time, the extended ends of the top plate 301 are suitable for ejecting wire rods of different thicknesses, increasing the range of applications.

[0024] Please see Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the top feeding mechanism 3 is equipped with a detection mechanism 5 for independent control of multiple wire rods. The detection mechanism 5 includes a support rod 501. The top end of multiple top plates 301 is vertically connected to the support rod 501. A sensor 502 is installed on the top of the support rod 501 by fasteners. The detection end of the sensor 502 faces the column 202. The installation of multiple support rods 501 facilitates the installation of multiple sensors 502. The detection end of the sensor 502 faces the column 202 to detect the wire rods outside the column 202. When no wire is detected on the wire rod, the sensor 502 sends a signal to the corresponding controller. The controller controls the corresponding electric push rod 302 to work, so as to push out the wire rod after the wire has been unwound.

[0025] Please see Figure 8As shown in this embodiment, the fastener is a bolt 503, and the sensor 502 has a trapezoidal structure. One end of the sensor 502 is slidably connected to the outside of the support rod 501. A bolt 503 is vertically threaded onto one end of the sensor 502, and one end of the bolt 503 extends to the inside of the sensor 502, abutting against the support rod 501. A threaded rod 504 is installed at the bottom of the support rod 501, and the threaded rod 504 is threadedly connected to the top plate 301. In this embodiment, the position of the sensor 502 is adjusted by sliding the sensor 502 against the support rod 501. The installation of the bolt 503 allows the sensor 502 to be positioned at the upper limit of the support rod 501. By rotating the bolt 503, the bolt 503 separates from the outside of the support rod 501, facilitating the sliding adjustment of the sensor 502. This method is convenient to operate, flexible in detection, and adaptable to wire rods of different heights. The threaded rod 504 facilitates the detachable replacement of the support rod 501.

[0026] Please see Figure 5 , Figure 6 and Figure 7 As shown, the top feeding mechanism 3 is equipped with a pushing mechanism 4 for pushing the wire bar to one side. The pushing mechanism 4 specifically includes a rotating block 402. The rotating block 402 is rotatably connected to the inner bottom of multiple top plates 301 (three top plates 301 in this embodiment) via a rotating shaft 404. The bottom of the rotating block 402 extends to the outer bottom of the top plate 301, and the top of the rotating block 402 extends to the outer top of the top plate 301. A contact spring 403 is connected between one side of the top of the rotating block 402 and the top plate 301. A push plate 401 is connected to the top of the rotating block 402, and the top of the push plate 401 is flush with the top of the top plate 301. The bottom of the rotating block 402 abuts against the top of the placement platform 201. The installation of the rotating block 402 enables the installation of the push plate 401. When the top plate 301 is in contact with the top of the placement platform 201, the rotating block 402 is abutted by the placement platform 201 and is released by the elastic force of the abutment spring 403 and stored inside the bottom of the top plate 301. At the same time, the push plate 401 is stored inside the top of the top plate 301, which facilitates the placement of the wire rod.

[0027] In a further optimized embodiment, when the top plate 301 rises and pushes out the bar, and the top plate 301 separates from the top of the placement platform 201, the rotating block 402 is not subject to external force. Under the resistance of the resistance spring 403, the rotating block 402 rotates in the opposite direction, so that the bottom of the rotating block 402 extends to the outside of the bottom of the top plate 301. The push plate 401 installed on the top of the rotating block 402 will rotate to the outside of the top of the top plate 301, and the angle between the push plate 401 and the top of the top plate 301 is 30°. When the bar is pushed out to the outside of the top of the column 202, with the cooperation of the push plate 401, the bar will tilt to one side, so that the bar can fall onto the conveyor belt 603 and be sent away for recycling.

[0028] Please see Figure 7As shown, in this embodiment, the rotating block 402 has a "Z"-shaped structure, and the push plate 401 has a "U"-shaped structure. One end of the push plate 401 is located on both sides of the column 202. The "Z"-shaped design of the rotating block 402 allows both ends of the rotating block 402 to be stored inside the sides of the top plate 301, without obstructing the placement of the wire rod. When the rotating block 402 rotates, it will tilt up, guiding the wire rod as it is pushed out. The "U"-shaped design of the push plate 401 makes it convenient for one end of the push plate 401 to be located on both sides of the column 202, effectively guiding the wire rod on the column 202.

[0029] Please see Figure 1 As shown, a conveying mechanism 6 for conveying the wire rods after unloading is installed at the bottom of the self-winding machine 1. The conveying mechanism 6 includes a mounting frame 601, which is located on one side of the placement platform 201. A conveyor belt 603 is rotatably connected to the mounting frame 601 via a drive assembly. In this embodiment, the drive assembly controls the conveyor belt 603, which rotates on the mounting frame 601 to convey the wire rods being collected. This facilitates recycling, is convenient to operate, saves time and labor, and improves recycling efficiency.

[0030] Please see Figure 1 As shown, the drive assembly specifically includes rollers 602. Multiple rollers 602 are rotatably connected to the mounting frame 601. The conveyor belt 603 is rotatably connected to the mounting frame 601 via the multiple rollers 602. A stepper motor 605 is mounted on the outer side of one end of the mounting frame 601. The output shaft of the stepper motor 605 is connected to the end of one of the rollers 602. Multiple equidistant protrusions 604 are mounted on the conveyor belt 603. In this embodiment, the stepper motor 605 is driven by an external controller, causing the rollers 602 to rotate, which in turn drives the conveyor belt 603 on the mounting frame 601 to rotate, thus achieving bar conveying. The protrusions 604 prevent the bars from slipping on the conveyor belt 603.

[0031] Please see Figure 2 and Figure 3 As shown, a guiding mechanism 7 for guiding the wire rods is installed on the placement platform 201. The guiding mechanism 7 specifically includes a support block 702. The support block 702 is installed on the placement platform 201, with one end of the support block 702 near the mounting frame 601. A guide plate 701 is installed on the support block 702, with an angle of 45° between the guide plate 701 and the placement platform 201. A rubber pad 703 is installed on the guide plate 701. In this embodiment, the installation of the support block 702 supports the guide plate 701. The guide plate 701 has a certain inclination angle (generally 30-45°), facilitating the smooth feeding of the ejected wire rods onto the conveyor belt 603. The rubber pad 703 serves to prevent wear.

[0032] The specific working process of this invention is as follows: In use, multiple wire rods are first placed on the placement platform 201. Multiple uprights 202 are used to position the wire rods, preventing them from slipping off the platform and facilitating the installation of the electric push rod 302. This also reduces the weight of the placement platform 201 and facilitates disassembly and maintenance of the uprights 202 and the platform 201, making operation convenient. When the wire rod is inserted into the outside of the upright 202, it serves as a guide and prevents internal wear and tear. With the installation of multiple top plates 301, after the wire rod is fitted with the upright 202, the bottom of the wire rod rests on the top of the top plate 301. Through the opening of the guide holes 303, and with the cooperation of multiple sets of driving components, the multiple top plates 301 are controlled to slide, thereby pushing the wire rod out of the upright 202 and completing the wire rod unloading process. With the installation of the electric push rod 302, driven by an external controller, the electric push rod 302 drives the top plate 301 to slide, thus ejecting the wire rod after it has been laid out. Simultaneously, the top plate 301 is extended at both ends to accommodate wire rods of different thicknesses, increasing its usability. Multiple support rods 501 are used to install multiple sensors 502, with the detection end of the sensors 502 facing the column 202, to detect the wire rod outside the column 202. When no wire is detected on the wire rod, the sensor 502 sends a signal to the corresponding controller, which then controls the corresponding electric push rod 302 to eject the wire rod after it has been laid out. The position of the sensor 502 can be adjusted by sliding it between the sensor 502 and the support rod 501. The installation of bolts 503 allows the sensor 502 to be positioned at the upper limit of the support rod 501. Rotating the bolts 503 separates them from the outer side of the support rod 501, facilitating the sliding adjustment of the sensor 502. This design is convenient, flexible, and adaptable to wire rods of different heights.

[0033] The push plate 401 is installed by the rotating block 402. When the top plate 301 is in contact with the top of the placement platform 201, the rotating block 402 is pushed away by the placement platform 201 and is stored in the inner bottom of the top plate 301 by the elastic force of the resisting spring 403. At the same time, the push plate 401 is stored in the inner top of the top plate 301, which facilitates the placement of the wire rod. When the bar is pushed out by the rising top plate 301, and the top plate 301 separates from the top of the placement platform 201, the rotating block 402 is not resisted by external force. Under the resistance of the resisting spring 403, the rotating block 402 rotates in the opposite direction, so that the bottom of the rotating block 402 extends to the outside of the bottom of the top plate 301. The push plate 401 installed on the top of the rotating block 402 will rotate to the outside of the top of the top plate 301, and the angle between the push plate 401 and the top of the top plate 301 is 30°. When the bar is pushed out to the outside of the top of the column 202, with the cooperation of the push plate 401, the bar will tilt to one side, so that the bar can fall onto the conveyor belt 603 and be sent away for recycling.

[0034] The drive components control the conveyor belt 603, which rotates on the mounting frame 601 to transport the collected bar stock. This facilitates recycling, is convenient to operate, saves time and effort, and improves recycling efficiency. An external controller drives the stepper motor 605, which in turn drives the roller 602 to rotate, thereby rotating the conveyor belt 603 on the mounting frame 601 to transport the bar stock. The installation of the protruding strip 604 prevents the bar stock from slipping on the conveyor belt 603. The installation of the support block 702 supports the guide plate 701. The guide plate 701 has a certain inclination angle, which facilitates the smooth feeding of the ejected bar stock onto the conveyor belt 603.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
