[0001] The present invention relates to the technical field of wire and cable production, and particularly relates to a wire reel conveying system and a wire reel conveying method. Background Art

[0002] Wire and cable is a general term for wire reels such as optical cables and power cables. Wire and cable has many uses, mainly for controlling installation, connecting equipment, transmitting electricity and other multiple functions, and is a common and essential object in daily life.

[0003] In the existing wire and cable production process, the method of manually rolling the reel and loading the reel from the side of the loading machine is often used to convey the wire reel to the stranding machine. However, this method will cause a large labor intensity of employees and reduce the production efficiency. Some employees will use the truss manipulator to directly load and unload the reel to reduce the labor intensity, but this method can only load and unload a single wire reel, and the conveying efficiency is not high. Moreover, the truss manipulator will lift and transport the wire reel and pass over the equipment, resulting in safety risks.

[0004] Therefore, there is an urgent need for a wire reel conveying system and a wire reel conveying method to solve the above technical problems. Summary of the Invention

[0020] To achieve this object, the present invention adopts the following technical solutions:

[0021] The wire drum conveying method comprises:

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] The following will introduce the wire reel conveying system and the wire reel conveying method provided by the present invention according to the attached Figures 1 to 9 It should be noted that the wire reel conveying system and the wire reel conveying method are mainly applicable to replacing wire reels for wire and cable production equipment such as the stranding machine 1, so as to ensure the continuous progress of production.

[0047] At least two workstations are circumferentially arranged on the stranding machine 1, and at least two wire reel mounting positions are arranged along the horizontal first direction (shown as the X axis in the figure) for each workstation. Refer to Figure 1 、 Figure 2As shown, in this embodiment, the wire reel conveying system includes a buffer table 3, a walking trolley 6, and a loading and unloading device 2. The buffer table 3 and the loading and unloading device 2 are arranged on one side of the stranding machine 1 along the horizontal second direction (shown as the Y-axis in the figure). The horizontal second direction and the horizontal first direction are perpendicularly arranged. The walking trolley 6 is used to convey the wire reel from the upstream device towards the buffer table 3. The buffer table 3 is provided with at least two buffer positions, and each buffer position can be used to store a wire reel. The at least two buffer positions are arranged along the horizontal first direction. The loading and unloading device 2 includes a horizontal walking mechanism 21, a horizontal telescopic mechanism 23, a lifting mechanism 24, and a clamping mechanism 25. The clamping mechanism 25 is used to clamp and release the wire reel. The horizontal walking mechanism 21 is used to move the loading and unloading device 2 along the horizontal first direction. The lifting mechanism 24 is used to lift and lower the clamping mechanism 25 in the vertical direction. The horizontal telescopic mechanism 23 is used to move the clamping mechanism 25 along the horizontal second direction. Along the horizontal second direction, the loading and unloading device 2 is arranged between the buffer table 3 and the wire and cable production equipment, and the loading and unloading device 2 can move along the horizontal first direction to move the wire reel between the buffer table 3 and the wire reel installation position, thereby realizing the replacement of the wire reel.

[0048] Specifically, taking the stranding machine 1 as an example, the upstream device continuously winds the preset-length cable core onto the wire reel (for the convenience of introduction, it is simply referred to as a full reel). After winding is completed, the full reel is carried to the buffer position for temporary storage. When there is a situation where the wire reel installation position on the stranding machine 1 lacks a wire reel, first, the horizontal walking mechanism 21 is used to move the loading and unloading device 2 to the position of the full reel to ensure that the clamping mechanism 25 is axially aligned with the full reel. Then, the horizontal telescopic mechanism 23 is used to extend the clamping mechanism 25 towards the buffer table 3 until the jaws of the clamping mechanism 25 are respectively located on both sides of the full reel, being in a state where the full reel can be clamped. Then, the full reel is clamped by the clamping mechanism 25, and the full reel is moved away from the buffer table 3 through the horizontal telescopic mechanism 23. After separation, the horizontal walking mechanism 21 is used to move the loading and unloading device 2 to the position lacking a reel, and then the horizontal telescopic mechanism 23 is used to move the clamping mechanism 25 and the full reel towards the stranding machine 1. And during the movement, the lifting mechanism 24 can adjust the height difference between the full reel and the wire reel installation position, so that the full reel can finally be installed on the corresponding wire reel installation position to complete the process of loading the reel.

[0049] Similarly, when the cable core on the frame stranding machine 1 is exhausted, that is, the full reel becomes empty, the horizontal walking mechanism 21 drives the upper and lower reel devices 2 to move to the front of the reel installation position where the empty reel is located, ensuring that the clamping mechanism 25 is axially aligned with the empty reel. Then, the horizontal telescopic mechanism 23 pushes the clamping mechanism 25 to extend toward the empty reel to clamp the empty reel. After the clamping is completed, the horizontal telescopic mechanism 23 retracts to smoothly extract the empty reel from the reel installation position, thereby separating the empty reel from the frame stranding machine 1. Immediately thereafter, the horizontal walking mechanism 21 moves the upper and lower reel devices 2 to the cache table 3, and places the reel on the cache position through the horizontal telescopic mechanism 23 and the lifting mechanism 24, completing the unloading process.

[0050] The above-mentioned wire reel conveying system replaces the existing manual rolling and side loading methods of the loading machine, greatly reducing the labor intensity of employees, improving production efficiency and avoiding safety risks.

[0051] Preferably, in this embodiment, the loading and unloading device 2 has at least two clamping mechanisms 25, each of which is used to clamp and release a wire reel. This allows the loading and unloading device 2 to load or unload multiple wire reels simultaneously, further improving loading and unloading efficiency.

[0052] like Figures 3 to 6 As shown, in this embodiment, the above-mentioned loading and unloading device 2 also includes a frame 201. The horizontal travel mechanism 21 includes a travel wheel 215, a first transmission chain 211, a travel drive shaft 213, a travel drive member 212, and a bearing 214. The travel wheel 215 is disposed at the bottom of the frame 201 and is connected to the travel drive shaft 213. The travel drive shaft 213 is rotatably mounted on the frame 201 via a bearing 214. The travel drive member 212 is fixedly mounted on the frame 201 and is in transmission connection with the travel drive shaft 213 via the first transmission chain 211. A track 4 is provided within the workshop. The track 4 extends along a first horizontal direction. Driven by the travel drive member 212, the travel wheel 215 can roll along the track 4, thereby moving the loading and unloading device 2 along the first horizontal direction.

[0053] The loading and unloading device 2 also includes a load plate 202. The lifting mechanism 24 includes a lifting rail pair 244, a second transmission chain 242, a lifting spindle 243, and a lifting drive 241. The load plate 202 is mounted on the frame 201 via the lifting rail pair 244, and each end of the load plate 202 is connected to a second transmission chain 242. The lifting spindle 243 and the lifting drive 241 are arranged at the top of the frame 201 and are connected by a third transmission chain. The lifting spindle 243 is connected to a second transmission chain 242 at each end, thereby connecting the load plate 202 and the lifting drive 241. Because both ends of the load plate 202 are connected to the second transmission chain 242, the entire load plate 202 can be raised and lowered smoothly. The clamping mechanism 25 and the horizontal telescopic mechanism 23 are arranged on the load plate 202, thereby enabling the clamping mechanism 25 to be adjusted in the vertical direction.

[0054] The horizontal telescopic mechanism 23 includes a plurality of horizontal slide rails 234 and a telescopic drive member 231. The horizontal slide rails 234 are disposed between the clamping mechanism 25 and the carrier plate 202, thereby slidably connecting the clamping mechanism 25 and the carrier plate 202. The telescopic drive member 231 is in transmission connection with the clamping mechanism 25 via a gear 232 and a rack 233. Driven by the telescopic drive member 231, the clamping mechanism 25 can be extended from the frame 201 along the second horizontal direction.

[0055] The clamping mechanism 25 includes a clamping driver 251, an upper clamping jaw 255, a lower clamping jaw 252, a sliding shaft 253, and a sliding sleeve 254. At least one of the upper clamping jaw 255 and the lower clamping jaw 252 is vertically adjustable via the sliding sleeve 254 to the sliding shaft 253, while the other is fixedly mounted in the height direction to the horizontal telescopic mechanism 23. Under the action of the clamping driver 251, the distance between the upper clamping jaw 255 and the lower clamping jaw 252 can be increased or decreased, thereby releasing and clamping the wire drum.

[0056] Preferably, in this embodiment, the frame 201 further includes a rotating plate 203, and a rotating mechanism 221 is disposed between the horizontal telescopic mechanism 23 and the supporting plate 202. Specifically, the rotating mechanism 221 includes a rotating motor mounted on the supporting plate 202. The rotating plate 203 is mounted above the rotating motor and is driven by the rotating motor to rotate vertically. The horizontal telescopic mechanism 23 is disposed between the rotating plate 203 and the clamping mechanism 25. The rotating mechanism 221 is capable of rotating the clamping mechanism 25 and the horizontal telescopic mechanism 23 vertically. Therefore, in this embodiment, the loading and unloading device 2 has a first state and a second state. In the first state, the rotating mechanism 221 rotates the horizontal telescopic mechanism 23 to a first predetermined angle, enabling the horizontal telescopic mechanism 23 to move at least two clamping mechanisms 25 to the buffering station 3. In the second state, the rotating mechanism 221 rotates the horizontal telescopic mechanism 23 to a second predetermined angle, enabling the horizontal telescopic mechanism 23 to move at least two clamping mechanisms 25 to the cable production equipment. After the rotating mechanism 221 is provided, it is possible to avoid providing a long horizontal slide rail pair 234 in the horizontal telescopic mechanism 23, thereby reducing the weight and increasing the efficiency of transporting the wire bobbin.

[0057] like Figure 7 As shown, in this embodiment, the wire reel conveying system further includes a handling device 5. The handling device 5 is arranged to be adjustable along a first horizontal direction. When the traveling trolley 6 stops at the buffering station 3, the handling device 5 can transfer the wire reel from the traveling trolley 6 to the handling device 5 and move it along the first horizontal direction, thereby transferring the wire reel to a preset buffer position.

[0058] Specifically, the transport device 5 includes a first traveling mechanism 51, a second traveling mechanism 52, a truss lifting mechanism 53, and a truss tilting mechanism 54. The first traveling mechanism 51 is used to move the transport device 5 in a first horizontal direction, while the second traveling mechanism 52 is capable of moving the truss lifting mechanism 53 and the truss tilting mechanism 54 in a second horizontal direction, enabling the truss tilting mechanism 54 to move in the second horizontal direction between the traveling trolley 6 and the buffering station 3. The truss lifting mechanism 53 is used to move the truss tilting mechanism 54 in a vertical direction to accommodate the height difference between the traveling trolley 6 and the buffering station.

[0059] Preferably, the truss turning mechanism 54 includes a manipulator that can rotate the wire reel and change the axial direction of the wire reel. For example, when the wire reel is transported from the upstream equipment to the traveling carriage 6, the axial direction of the wire reel is arranged in the horizontal direction. The manipulator can rotate the wire reel to the vertical direction while transferring the wire reel to the buffer position, thereby allowing the wire reel to be placed in the buffer position more stably.

[0060] The present invention also provides a method for transporting wire reels, which is implemented by the above-mentioned wire reel transportation system. Referring to Figure 8 , Fig. 9 as shown, the wire reel transportation method includes:

[0061] S1. Transfer a full reel from the upstream equipment to the buffer position of the buffer table 3 through the walking trolley 6 and wait for the wire production equipment to send a reel change signal;

[0062] S2. After receiving the reel change signal, first separate the empty reel on the wire production equipment from the wire production equipment, and use the reel loading and unloading equipment 2 to transport the empty reel from the wire production equipment to the buffer position, and transport the full reel from the buffer position to the wire production equipment.

[0063] It should be noted that the above steps S1 and S2 can be carried out simultaneously. For example, while transferring the wire reel to the buffer position through the walking trolley 6, the reel loading process or the reel unloading process is carried out through the reel loading and unloading equipment 2.

[0064] Exemplarily, when the core in the stranding machine 1 is exhausted, that is, the full reel becomes an empty reel, the stranding machine 1 sends a reel change signal to the wire reel transportation system and stops the stranding process, switching to the manual mode. The operator can reach the stranding machine 1 and cut the core, so that the wire reel is separated from the stranding machine 1. After separation, a terminal is pressed at the end of the wire connected to the stranding machine 1 for connection with the wire on the replaced full reel. After the wire reel transportation system receives the reel change signal, it first waits for the terminal pressing to be completed. After the terminal pressing is completed, the reel loading and unloading equipment 2 moves along the track 4 to the front of the wire reel installation position where the empty reel is located, ensuring that the clamping mechanism 25 is axially aligned with the empty reel. Then, the horizontal telescopic mechanism 23 pushes the clamping mechanism 25 towards the empty reel to clamp the empty reel. After the clamping is completed, the horizontal telescopic mechanism 23 retracts to smoothly extract the empty reel from the wire reel installation position, realizing the separation of the empty reel and the stranding machine 1. Immediately afterwards, the horizontal walking mechanism 21 moves the reel loading and unloading equipment 2 to the buffer table 3, and through the horizontal telescopic mechanism 23, the lifting mechanism 24 and the rotating mechanism 221, places the wire reel on the buffer position, completing the reel unloading process. Subsequently, the above-mentioned reel loading process is carried out. After the reel loading is completed, the operator can switch the manual mode to the automatic mode and restart the stranding machine 1.

[0065] Through this wire reel transportation method, the existing methods of manually rolling the reel and loading the reel from the side of the reel loading machine are replaced, greatly reducing the labor intensity of employees, improving the production efficiency, and avoiding safety risks. Moreover, this wire reel transportation method can be applied to different models of stranding machines 1 (mainly due to different wire reel installation positions), so that this wire reel transportation system has better compatibility.

[0066] For example, taking the upper and lower drum devices 2 having two clamping mechanisms 25 as an example, each clamping mechanism 25 is installed through an independent horizontal telescopic mechanism 23 and can be independently extended and retracted. When a workstation has two wire drum installation positions, the two clamping mechanisms 25 can simultaneously perform the upper and lower drum processes or the lower and lower drum processes, thereby transporting two wire drums at a time; when a workstation has three wire drum installation positions, the two clamping mechanisms 25 can first simultaneously transport the two wire drums, perform the upper and lower drum processes or the lower and lower drum processes on two of the wire drum installation positions, and then use one of the clamping mechanisms 25 to perform the upper and lower drum processes or the lower and lower drum processes on the remaining wire drum installation position. Similarly, when a workstation has five wire drum installation positions, four of the wire drum installation positions can first be divided into two groups to perform the upper and lower drum processes or the lower and lower drum processes, and then the remaining wire drum installation position can perform the upper and lower drum processes or the lower and lower drum processes. Therefore, through this wire drum conveying method, the wire drum conveying system can be applied to different models of frame stranding machines 1.

[0067] Optionally, a safety guardrail is further provided at the frame winch 1 . Before switching to the automatic mode, the safety guardrail is closed and prohibits the operator from approaching the frame winch 1 .

[0068] Optionally, the wire drum conveying method further comprises:

[0069] S3. The full tray is transferred from the traveling trolley 6 to the cache position by the handling device 5.

[0070] It should be noted that step S2 and step S3 can be performed simultaneously without interference, that is, the handling equipment 5 can place the full plate on the buffer table 3 without interfering with the upper and lower plate equipment 2, and at this time the upper and lower plate equipment 2 can transport the full plate to the frame winch 1, or transport the empty plate to the buffer table 3.

[0071] Optionally, the wire drum conveying method further comprises:

[0072] S4, transferring the empty disc from the buffer location to the traveling trolley 6 by the transport device 5, and transferring the empty disc from the traveling trolley 6 to the upstream device by the traveling trolley 6.

[0073] By step S4, the empty disk can be transported to an upstream device (e.g., a wire drawing machine), whereupon the cable core is wound around the empty disk to form a new full disk. The traveling trolley 6 can also achieve maximum utilization and avoid the phenomenon of no-load.

[0074] Preferably, the wire drum conveying method further comprises:

[0075] In the process of transferring a full tray from the traveling trolley 6 to the cache position by the transporting device 5, the axial direction of the full tray is changed, and in the process of transferring an empty tray from the cache position to the traveling trolley 6 by the transporting device 5, the axial direction of the full tray is changed.

[0076] Exemplarily, in this embodiment, when the wire reel is placed on the walking trolley 6, its axis direction is horizontal, which facilitates the process of moving from the upstream equipment to the walking trolley 6. When the wire reel is placed on the buffer table 3, its axis direction is vertical, thus ensuring the stability during placement. Therefore, by adding an action to change the axis direction during the process of the wire reel moving from the walking trolley 6 to the buffer table 3, the portability of connection with the upstream equipment and the stability when placed on the buffer table 3 can be taken into account.

[0077] Furthermore, in this embodiment, the wire reel conveying system further includes a control component capable of verifying material information. Exemplarily, the control component can obtain production information from the upstream equipment and verify the production information with the material information obtained or stored by the walking trolley 6, the handling equipment 5, and the buffer table 3.

[0078] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
