Description

Technical Field

[0001] This application relates to the field of loading and unloading technology for stranding machines, specifically an automatic loading and unloading device for stranding machines. Background Technology

[0002] In the wire and cable manufacturing industry, the bundling machine is a core piece of equipment used to bundle multiple single metal wires or strands together. Its efficiency and stability directly affect production quality and cost. Traditional bundling machines require frequent changes of the wire reel (i.e., the tooling reel that carries the wire) during operation, and the loading and unloading operations in existing technologies mostly rely on manual or semi-automated auxiliary equipment.

[0003] Most companies use manual handling combined with simple hoisting devices to load, unload, and position wire reels. This method is not only labor-intensive and inefficient, but also poses safety hazards. In addition, manual operation is prone to misalignment between the wire reel and the spindle due to insufficient positioning accuracy, which can lead to equipment downtime or wire damage, seriously affecting the continuous production rhythm.

[0004] In recent years, some manufacturers have attempted to achieve semi-automatic loading and unloading of wire reels using robotic arms or rail-mounted conveyor systems, but these solutions still have significant drawbacks. Traditional rail-mounted systems have poor adaptability to wire reel specifications, requiring frequent adjustments to the mechanical structure or replacement of tooling fixtures, making it difficult to meet the flexible production needs of multiple varieties and small batches.

Figure 3 The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. When a feature is referred to as "set", "fixed", or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0025] Please see Figure 1-3 This application provides the following technical solution: an automatic loading and unloading device for a stranding machine, including a feeding mechanism and a loading and unloading mechanism; the feeding mechanism includes a chain conveyor 8, and an empty wire reel 1 and a raw material wire reel 5 are placed on the upper surface of the chain conveyor 8.

[0026] Specifically, the chain conveyor 8 is used to transport new raw material reels 5 to the gripping station of the loading and unloading mechanism, and to transport empty reels 1 unloaded from the stranding machine to the recycling station.

[0027] The loading and unloading mechanism includes two X-axis linear motors 4 arranged symmetrically on the left and right. The lower surface of the X-axis linear motors 4 is provided with hydraulic telescopic rods 9 at both ends. A Y-axis linear motor 2 is mounted on the slide of the X-axis linear motor 4. A connecting rod 3 is mounted on the slide of the Y-axis linear motor 2. A stepper motor 18 is fixedly connected to the lower surface of the connecting rod 3. The output shaft of the stepper motor 18 is fixedly connected to a sleeve 19 through a coupling. The sleeve 19 is connected to a portal frame 12 through a positioning rod 17 set on its lower end face. The outer side of the portal frame 12 is provided with L-shaped shovels 13 at both ends. The outer side of the sleeve 19 is provided with electrically controlled telescopic rods 10 at both ends. A U-shaped pressure plate 11 is installed on the lower surface of the electrically controlled telescopic rods 10.

[0028] Specifically, the X-axis linear motor 4 is used to drive the L-shaped shovel plate 13 to move back and forth, the Y-axis linear motor 2 is used to drive the L-shaped shovel plate 13 to move left and right, and the stepper motor 18 is used to drive the L-shaped shovel plate 13 to rotate and adjust, so as to realize the switching of different clamping positions. The L-shaped shovel plate 13 is used to lift the wire reel from the bottom. After the electric telescopic rod 10 is extended, it can press the U-shaped pressure plate 11 tightly against the upper surface of the wire reel, so that the wire reel will not fall off when it moves with the L-shaped shovel plate 13.

[0029] Furthermore, the feeding mechanism is located at the front end of the lower surface of the loading and unloading mechanism.

[0030] Specifically, the feeding mechanism is used to transport new raw material reels 5 to the gripping station of the loading and unloading mechanism, and to transport empty reels 1 unloaded from the stranding machine to the recycling station.

[0031] Furthermore, a tray 7 is installed on the chain plate of the chain conveyor 8, and a positioning shaft 6 is provided in the middle of the upper surface of the tray 7. The positioning shaft 6 is sleeved and correspondingly set with the empty wire reel 1.

[0032] Furthermore, both ends of the tray 7 are provided with notches for placing the L-shaped shovel plate 13.

[0033] Specifically, tray 7 is a round disc with notches at both ends.

[0034] Furthermore, a base 14 is installed on the lower end face of the hydraulic telescopic rod 9, a positioning plate 15 is installed on the lower end of the outer side of the hydraulic telescopic rod 9, and at least one lifting rod 16 is provided on the lower surface of the X-axis linear motor 4. The lifting rod 16 passes through the through hole provided on the positioning plate 15 and is arranged vertically.

[0035] Specifically, the lifting rod 16 increases the torsional resistance of the hydraulic telescopic rod 9.

[0036] Furthermore, the inner side of the sleeve 19 is rotatably connected to the outer side of the connecting rod 3 via a bearing.

[0037] Furthermore, the openings of both the L-shaped shovel plate 13 and the U-shaped pressure plate 11 are wider on the outside and narrower on the inside.

[0038] Specifically, this design allows the L-shaped shovel plate 13 to scoop up different types of coils.

[0039] Furthermore, the middle part of the L-shaped shovel plate 13 is connected to the gantry bracket 12, so that the left and right ends of the L-shaped shovel plate 13 form two independent shovel structures.

[0040] Specifically, there are two independent workstations, one for grabbing empty wire reel 1 and the other for grabbing raw material wire reel 5.

[0041] In use: Place the raw material reel 5 on the upper surface of the tray 7, while ensuring that the raw material reel 5 can be sleeved on the positioning shaft 6. Start the chain conveyor 8. The chain conveyor 8 drives the raw material reel 5 to move towards the loading station. After the raw material reel 5 moves to the loading station.

[0042] By controlling the Y-axis linear motor 2 and the X-axis linear motor 4, the L-shaped shovel 13 is inserted below the empty wire reel 1 on the bundling machine. Then, the hydraulic telescopic rod 9 extends to lift the empty wire reel 1, and the synchronously controlled electric telescopic rod 10 extends to press the U-shaped pressure plate 11 tightly onto the empty wire reel 1.

[0043] After the empty reel 1 is removed, the hydraulic telescopic rod 9 retracts, causing the L-shaped shovel 13 to move downwards. When the L-shaped shovel 13 moves to a position slightly lower than the raw material reel 5, the Y-axis linear motor 2 and the X-axis linear motor 4 are controlled to insert the L-shaped shovel 13 below the raw material reel 5. Then, the hydraulic telescopic rod 9 extends to lift the raw material reel 5, and the corresponding electrically controlled telescopic rod 10 extends to press the U-shaped pressure plate 11 tightly onto the raw material reel 5.

[0044] Then, the stepper motor 18 drives the sleeve 19 to rotate 180 degrees, so that the empty wire reel 1 on the L-shaped shovel plate 13 rotates to be directly above the positioning shaft 6. After the hydraulic telescopic rod 9 retracts and puts the empty wire reel 1 onto the positioning shaft 6, the L-shaped shovel plate 13 moves away. By controlling the Y-axis linear motor 2 and the X-axis linear motor 4, the raw material wire reel 5 is moved to the loading position of the stranding machine. Then, the hydraulic telescopic rod 9 retracts and puts the raw material wire reel 5 onto the raw material shaft of the stranding machine. Finally, the L-shaped shovel plate 13 is moved away by the Y-axis linear motor 2 and the X-axis linear motor 4.

[0045] It is worth noting that in this application, the input ends of the Y-axis linear motor 2, X-axis linear motor 4, chain conveyor 8, electrically controlled telescopic rod 10 and stepper motor 18 are all electrically connected to the output end of an external power supply through an external control switch, and the extension and retraction of the hydraulic telescopic rod 9 is controlled by an external hydraulic station.

[0046] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
