Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, and particularly relates to an automatic wire reel turning and moving device, and further relates to a stranding system including the automatic wire reel turning and moving device. Background Art

[0002] In industries such as wire and cable, it is often necessary to perform processes such as extrusion, stranding, tape wrapping, armoring, wire drawing or braiding on wires, branch wires, stranded wires, composite wires and other wire and cables, or to perform inspection operations. During the above-mentioned processes or operations, wires, branch wires, stranded wires, composite wires and other cables are usually wound on wire reels, and the predetermined processes or operations are carried out by moving the wire reels.

[0003] For lighter loaded wire reels or empty wire reels, although they can be turned and moved manually, the labor intensity is high and the efficiency is low. For heavier loaded wire reels, existing lifting equipment is required to turn and move them. However, due to the small volume and large weight of the wire reels, using existing lifting equipment not only makes the operation complex, but also difficult to meet the need of turning and moving wire reels in a small space, resulting in low efficiency of wire reel turning and moving.

[0004] With the improvement of the efficiency of cable processing equipment, the time for specific processing or operation of cables is getting shorter and shorter, and thus it is necessary to turn and move wire reels frequently; this makes wire reel turning and moving become the short board and bottleneck of cable production. Therefore, how to efficiently realize the turning and moving of wire reels in cable production is a problem that needs to be solved by those skilled in the art currently.

[0012] In the preferred technical solution, the first grasping end plate has fork claws corresponding to the outer periphery of the convex end face of the wire reel, and the inner side has a contour that matches the peripheral surface of the wire reel stop baffle; at least part of the inner side of the second grasping end plate has a contour that matches the other end face of the wire reel. In this way, when grasping the wire reel, on the one hand, the fork claws are inserted into the bottom of the wire reel, and on the other hand, the wire reel is fixed through the matching contour, providing a basis for operations such as flipping, transferring, loading, or unloading the wire reel.

[0030] The following will describe the wire spool automatic flipping and transferring device provided in the embodiments of this application with reference to the accompanying drawings. It should be noted that, for the convenience of description and understanding, in this patent, "horizontal", "vertical", "front", "rear", "left", and "right" are determined based on the usage state of the device, mechanism, stranding machine, and stranding system in the specific implementation solution, and do not constitute a limitation on the protected technical solution.

[0031] For the convenience of description and to shorten the length, in this part, while describing the stranding system, the wire spool automatic flipping and transferring device will be described, and the wire spool automatic flipping and transferring device will not be described separately.

[0032] As Figure 1 And Figure 2 Shown, Figure 1 This is a partial layout diagram of the stranding system provided in the embodiments of this patent. The situation of one stranding machine is schemed in the figure. The actual stranding system is a part of the stranding production line and may include multiple stranding machines for performing predetermined winding processing on branch wires. Figure 2 Is Figure 1 The structure diagram of another angle of the partial layout of the stranding system shown.

[0033] In this embodiment, the stranding system includes an existing stranding machine 200 that specifically performs stranding, and also includes a fixing frame 300. The fixing frame 300 forms a frame that covers a certain area. The stranding machine 200 is located within the frame formed by the fixing frame 300, that is, the fixing frame 300 surrounds the stranding machine 200 to facilitate the operation of loading the spool (i.e., installing the spool on the appropriate part of the stranding machine 200) or unloading the spool (i.e., removing the spool from the predetermined part of the stranding machine 200).

[0034] In this embodiment, the fixing frame 300 forms two horizontal sliding rails 301; the two horizontal sliding rails 301 are respectively located in front of and behind the stranding machine 200 and are parallel to each other. In a preferred embodiment, the extending direction of the horizontal sliding rail 301 is parallel to the winding axis of the stranding machine 200. This allows the later-described spool automatic turning and moving device 100 and spool changing device 400 to move along the winding axis, and thus can provide support for the stranding machine 200 within a larger range. The fixing frame 300 may include a horizontally extended transverse frame body and a plurality of support legs of a certain height, so that the horizontal sliding rail 301 has a certain height while facilitating the layout of the stranding system and the corresponding production line.

[0035] In this embodiment, the stranding system further includes a sliding rail driving mechanism and a spool automatic turning and moving device 100.

[0036] Combined Figure 1 and Figure 2 , the spool automatic turning and moving device 100 includes a first support frame 110, a first translation connection frame 120, and a turning head 130; the first translation connection frame 120 is installed on the first support frame 110; the first support frame 110 can be installed on a suitable support mechanism. In this embodiment, the first support frame 110 is installed on the fixing frame 300 and is slidably engaged with the horizontal sliding rail 301; the sliding rail driving mechanism drives the first support frame 110 to move in the left-right direction relative to the horizontal sliding rail 301. The sliding rail driving mechanism can be a known mechanism, such as a gear-rack mechanism, a threaded screw mechanism, etc.

[0037] This enables the spool automatic turning and moving device 100 to move in the winding axis direction, allowing the spool automatic turning and moving device 100 to perform turning, moving, and other operations on the wires of the stranding machine 200, thereby improving the efficiency and safety of the overall system.

[0038] Please refer to Figure 3 and Figure 4 , Figure 3 is a three-dimensional structural schematic diagram of the turning head 130 of the spool automatic turning and moving device in this embodiment, showing the state of cooperation with grasping the spool in this figure. Figure 4 is Figure 3The side view structure of the shown turnover head 130. The turnover head 130 includes a turnover frame 131 and a coil grab mechanism 132; the coil grab mechanism 132 includes a grab substrate 1321, a first grab end plate 1322, a second grab end plate 1323, and a clamping power mechanism 1324.

[0039] The root of the first grab end plate 1322 is fixedly connected to the grab substrate 1321 to form a fixed part for supporting the coil. The root of the second grab end plate 1323 is slidably engaged with the grab substrate 1321 in the horizontal direction to form a movable part to meet the needs of grabbing and fixing. The first grab end plate 1322 and the second grab end plate 1323 respectively extend outward in parallel, and a coil fixing space is formed between them. It can be understood that for the grabbing and releasing of the coil, the first grab end plate 1322 and the second grab end plate 1323 can be set to suitable shapes or structures.

[0040] Generally speaking, the coil includes a middle cylinder and stop baffles 602 located at both ends of the middle cylinder. In order to facilitate movement, protrusions 601 are usually provided on the end faces. Based on the shape of the coil, the first grab end plate 1322 and the second grab end plate 1323 can have suitable structures, such as Figure 3 shown.

[0041] Please refer to Figure 5 , Figure 5 For Figure 4 is Figure 3 Another perspective three-dimensional structure diagram of the shown turnover head 130, in which the position of grabbing the coil is not shown. The first grab end plate 1322 has fork claws a corresponding to the outer peripheral surface of the protrusion 601 on the end face of the coil, and a contour b on the inner side surface that cooperates with the peripheral surface of the stop baffle 602 of the coil. The inner side surface of the second grab end plate 1323 at least has a part of the contour that cooperates with the other end face of the coil. Of course, it can also have a structure symmetrical to that of the first grab end plate 1322. In this way, when grabbing the coil, on the one hand, the fork claws a are inserted into the bottom of the coil, and on the other hand, the coil is fixed through the cooperating contours, providing a basis for turnover, transfer, coil loading or unloading operations.

[0042] Both ends of the clamping power mechanism 1324 are respectively connected to the first grab end plate 1322 and the second grab end plate 1323 to change the distance between the first grab end plate 1322 and the second grab end plate 1323. The clamping power mechanism 1324 can be a telescopic device to drive the second grab end plate 1323 to move relative to the grab substrate 1321, such as a hydraulic cylinder, a linear motor, etc. In this embodiment, two cylinders are used to provide power.

[0043] The flipping frame 131 is rotatably mounted on the first translation connecting frame 120 about a vertical axis, so that the grasped wire reel can be rotated about the vertical axis. The grasping substrate 1321 is rotatably mounted on the flipping frame 131 about a horizontal axis. It can be understood in the rotatable manner that a rotating shaft and a shaft hole cooperating with the rotating shaft can be provided, and a suitable bearing or other rotation matching mechanisms can also be provided between the rotating shaft and the shaft hole.

[0044] Meanwhile, it further includes a first vertical rotation driving mechanism 101 and a horizontal rotation driving mechanism 102. The first vertical rotation driving mechanism 101 is used to drive the flipping frame 131 to rotate about the vertical axis relative to the translation connecting frame 120. The horizontal rotation driving mechanism 102 drives the grasping substrate 1321 to rotate about the horizontal axis relative to the flipping frame 130. In this way, the grasped wire reel can be rotated about the horizontal axis; furthermore, the attitude of the wire reel can be automatically adjusted in two dimensions, facilitating the operations of loading or unloading the reel. The rotation driving mechanism can be a known structure. In this embodiment, the driving mechanism includes a worm and worm gear mechanism.

[0045] The way of using the top cone to expand and contract to fix the wire reel involved in the patent application of the patent applicant with the previous patent application number 202420039449.8 and the name of "a wire reel automatic flipping and moving mechanism". Since this way requires setting a top cone and a second grasping end plate for installing the top cone, it results in a large extra size and is prone to collide with the wire reel. In the embodiment of this patent, the flipping head 130 changes the distance between the first grasping end plate 1322 and the second grasping end plate 1323 through the clamping power mechanism 1324 to realize the fixation and release of the wire reel, which can reduce interference. In this way, a predetermined wire reel can be grasped or released, and then the operations of loading or unloading the reel can be carried out.

[0046] In this way, during the cable production, the flipping frame 131 can be placed in a suitable position through the first vertical rotation driving mechanism 101, and the wire reel grasping mechanism 132 can be made opposite to the wire reel to be grasped through the horizontal rotation driving mechanism 102; after grasping the wire reel, the position of the flipping frame 131 is changed through the first vertical rotation driving mechanism 101, and the wire reel grasping mechanism 132 is rotated through the horizontal rotation driving mechanism to realize the position movement and rotation of the wire reel, achieve the flipping and movement of the wire reel, improve the efficiency of wire reel flipping and moving, promote the cable production efficiency, and improve the safety of cable production.

[0047] Refer again to Figure 1, in this embodiment, the wire reel automatic turning and shifting device 100 further includes a first vertical driving mechanism and a first vertical moving frame 140 movably installed on the first translation connecting frame 120 in the vertical direction. The flipping frame 131 is rotatably installed on the first translation connecting frame 120 through the first vertical moving frame 140 and rotates around a vertical axis. The first vertical driving mechanism is used to drive the first vertical moving frame 140 to move relative to the first translation connecting frame 120 in the vertical direction. In this way, the height position of the flipping head 130 can be adjusted in the vertical direction to perform grasping or releasing operations on wires in a larger space, improving the adaptability of the wire reel automatic turning and shifting device.

[0048] In addition, in this embodiment, the wire reel automatic turning and shifting device 100 further includes a first front-back driving mechanism. The first translation connecting frame 120 is movably installed on the first support frame 110 in the front-back direction. The first front-back driving mechanism is used to drive the first translation connecting frame 120 to move relative to the first support frame 110 in the front-back direction. In this way, the position of the flipping head 130 can be adjusted in the front-back direction to perform grasping or releasing operations on wires in a larger space, improving the adaptability of the wire reel automatic turning and shifting device.

[0049] Refer again to Figure 1 and Figure 2 , in this embodiment, the stranding system further includes a wire reel replacement device 400. The wire reel replacement device 400 can cooperate with the above-mentioned wire reel automatic turning and shifting device 100 to perform corresponding operations on the wire reel.

[0050] The wire reel replacement device 400 includes a second support frame 410, a second vertical moving frame 420, a second vertical driving mechanism, and a pick-and-place reel assembly 430. The second support frame 410 is slidably engaged with the horizontal slide rail 301 in a left-right movable manner. The second vertical moving frame 420 is movably installed on the second support frame 410 in the vertical direction. The second vertical driving mechanism drives the second vertical moving frame 420 to move relative to the second support frame 410 in the vertical direction.

[0051] Please refer to Figure 6 and Figure 7 , Figure 6 is a schematic three-dimensional structure diagram of the pick-and-place reel assembly 430 of the wire reel replacement device 400 in this embodiment, Figure 7 is Figure 6 the front view structure of the flipping head 130 shown.

[0052] The pick-and-place tray assembly 430 includes a pick-and-place tray frame 431, a pallet 432 fixed to the pick-and-place tray frame 431, a pressing plate 433, and a pressing drive member 434. The pallet 432 cooperates with a predetermined wire reel to obtain or release the predetermined wire reel. The pressing plate 433 corresponds to the pallet 432 to form a wire reel fixing device. The pressing drive member 434 is installed between the pick-and-place tray frame 431 and the pressing plate 433, and simultaneously controls the position of the pressing plate 433 so that the pallet 432 and the pressing plate 433 form a space for fixing the wire reel. The pressing drive member 434 can move the pressing plate 433 relative to the pallet 432, thereby fixing or releasing the predetermined wire reel. The pressing drive member 434 can be an actuating mechanism or component such as a hydraulic cylinder or a pneumatic cylinder.

[0053] The pick-and-place tray frame 431 is rotatably connected to the first vertical moving frame 420 about a vertical axis.

[0054] The wire reel changing device 400 further includes a second vertical rotation drive mechanism 401 that drives the pick-and-place tray frame 431 to rotate about a vertical axis relative to the second vertical moving frame 420. On the one hand, the wire reel changing device 400 can perform replacement operations (including loading and unloading operations) for all the stranding machines 200 in the fixing frame 300, improving the wire reel replacement efficiency and ensuring safety. On the other hand, the wire reel changing device 400 and the wire reel automatic turning device 100 are located in the same fixing frame 300, and the two can cooperate to perform wire reel operations, enabling the wire reel to be transferred in the stranding system, thereby providing a prerequisite for the storage and arrangement of wires in the stranding system.

[0055] In this embodiment, in the wire reel changing device 400, the pressing plate 433 is slidably engaged with the pick-and-place tray frame 431 in the vertical direction through a cooperating slider 651 and a slide rail 652. This can ensure the reliable fixation of the wire reel and the flexibility of picking and placing the reel. Of course, the pressing plate 433 can also be directly mounted on the pressing drive member 434 to control its position through the pressing drive member 434. The wire reel changing device 400 can utilize the wire reel changing device described in the patent application with the patent number "2024204119767" and the invention title "A Stranding Machine and Its Full-Automatic Wire Reel Changing Device" applied by the patent applicant, which can move the pick-and-place tray assembly 430 in three-dimensional space. The pick-and-place assembly 430 includes at least two wire reel fixing devices to improve the replacement efficiency.

[0056] As Figure 1 and Figure 2As shown, in the preferred technical solution, the stranded wire system further includes a wire reel transition storage rack 500 for storing the wire reels in a vertical axis manner, which is used to store the wire reels removed by the wire reel replacement device 400 during the lower disk operation, thus facilitating the grasping by the wire reel automatic turning device 100. At the same time, it is also used to store the wire reels released by the wire reel automatic turning device 100, thus facilitating the taking of the wire reels by the wire reel replacement device 400.

[0057] In an alternative technical solution, the wire reel replacement device 400 is matched with the position of the stranding machine 200 to perform the upper disk or lower disk operation on the stranding machine 200.

[0058] Through the position coordination of the wire reel replacement device 400, the wire reel automatic turning device 100 and the stranding machine 200, efficient management of the wire reels can be achieved. For example, the wire reel replacement device 400 can obtain a full wire reel from the transition storage rack 500, then move within the fixed rack 300 to a position corresponding to the stranding machine 200, and make the full wire reel correspond to the stranding machine 200 by rotation, and install the full wire reel on the stranding machine 200 to complete the upper wire operation. It can also remove the empty wire reel of the stranding machine 200 and store the empty wire reel on the transition storage rack 500 through movement and rotation. Similarly, the wire reel automatic turning device 100 can obtain an empty wire reel from the transition storage rack 500 (the axis extends vertically for storage), then move within the fixed rack 300 to a predetermined position, such as Figure 2 the position of the unified wire reel inlet and outlet W shown in the figure, and make the axis of the empty wire reel extend horizontally, so that the empty wire reel can roll automatically; and it can make the full wire reel correspond to the transition storage rack 500 by rotation at the unified wire reel inlet and outlet W, and place the full wire reel on the transition storage rack 500 (the axis extends vertically for storage), facilitating the taking of the wire reel by the wire reel replacement device 400. In the preferred technical solution, the stranded wire system includes a plurality of stranding machines 200 arranged along the winding center line. Through the above coordination, the wire reels can be uniformly stored at a predetermined position (such as the transition storage rack 500) during the upper disk operation or the lower disk operation, and the wire reels of the entire production line can enter or exit through a unified wire reel inlet and outlet W, which can greatly improve the efficiency, save space, improve safety, and reduce the labor intensity. When the wire reel taking component 430 of the wire reel replacement device 400 includes two wire reel fixing devices, the efficiency can be improved to a greater extent.

[0059] It can be understood that the wire reel automatic turning device 100 can be matched with the position of the stranding machine 200 to perform the upper disk or lower disk operation on the stranding machine 200.

[0060] Figure 8This patent's another embodiment provides an overall layout diagram of a stranding system. The stranding system includes three stranding machines 200 for performing predetermined winding processes on branch lines. A fixing frame 300 surrounds the three stranding machines 200 and includes a wire reel automatic turning device 100 and a wire reel replacement device 400. Through the cooperation of the wire reel automatic turning device 100 and the wire reel replacement device 400, wire reels can be uniformly stored in a predetermined position (such as a transition storage rack 500) during the process of loading or unloading the upper or lower wire reels, enabling the wire reels of the entire production line to enter or exit through a unified wire reel inlet and outlet. Thus, the efficiency can be greatly improved, space can be saved, safety can be enhanced, and labor intensity can be reduced.

[0061] Finally, it should be noted that the above-mentioned wire reel automatic turning device and stranding system can be applied to the production of wires and cables, and can also be used in other processes of cable and wire and rope synthesis, such as stranding, tape winding, armoring, wire drawing, or weaving, etc. Obviously, the above embodiments are merely examples given for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
