Automatic conversion device for accumulated and withdrawn wire and pay-off wire

Abstract

The present application discloses an automatic conversion device for accumulated and withdrawn wire pay-off, comprising a column and an accumulated and withdrawn wire wheel. When steel wire is wound on the accumulated and withdrawn wire wheel, n turns of steel wire are wound on the first wheel portion, and n turns of steel wire are also wound on the second wheel portion, where n>0. After the steel wire wound around the first wheel portion passes through the wire threading portion and then around the second wheel portion, the winding direction of the steel wire on the first wheel portion is opposite to the winding direction of the steel wire on the second wheel portion. As a result, the steel wire in the wire threading portion is separated from the wire threading portion, or the steel wire in the wire threading portion is moved in the opposite direction of the wire winding, thereby releasing the steel wire on the accumulated and withdrawn wire wheel, thereby regulating the tension of the steel wire during the reeling process.

[0026] The present application provides an automatic conversion device for accumulating, withdrawing and paying off wires, comprising: a column 1, on which a first material tray 2 and a second material tray 3 are provided, the first material tray 2 and the second material tray 3 being used to load steel wires;

[0027] The wire accumulation and withdrawal wheel 20 is provided on one side of the column 1 , and includes a first wheel portion 21 , a second wheel portion 22 and a wire threading portion 23 .

[0028] When one of the first and second trays 2 and 3 is the working tray, the other is the standby tray. It should be noted that the wire on the working tray is in use, being pulled and continuously released from the working tray and moving forward, causing the amount of wire on the working tray to decrease. The wire on the standby tray is in a standby state. When the wire on the working tray is exhausted, the standby tray replaces the working tray for wire feeding.

[0029] As you can easily understand, without an automatic reel changer, when a reel runs out of wire, the machine must be shut down, manually replaced with a new reel, and the head of the new reel connected to the end of the used wire before the machine can be restarted to ensure continued wire flow. This manual operation is time-consuming and labor-intensive, and also affects the efficiency of the machine.

[0030] Through the automatic conversion device for accumulated, withdrawn and paid-off wires provided by the present application, after the steel wire on the working material tray is laid out, the spare material tray can automatically replace the working material tray, thereby allowing the steel wire to be continuously produced, so that the steel wire production line can continue to work.

[0031] It is important to note that when a spare tray takes over from a working tray and releases the wire, it becomes the new working tray. Similarly, when all the wire on a working tray is released, the tray becomes empty and is no longer a "working tray." A new spare tray can be obtained by loading new wire onto the empty tray, or by removing the empty tray and replacing it with a new one loaded with wire.

[0032] For the convenience of the following description, the steel wire on the working tray is called the working steel wire, and the steel wire on the spare tray is called the spare steel wire.

[0033] Specifically, the head end of the steel wire on the standby material tray is wound around the wire-receiving wheel 20 and connected to the end of the steel wire on the working material tray. In this way, the standby steel wire is connected to the working steel wire at both ends. As the working steel wire is continuously paid out, the end of the working steel wire is pulled, and the standby steel wire can be pulled along with it.

[0034] Optionally, the end of the working steel wire is welded to the head end of the spare steel wire. By welding the two coils of steel wire, the stability of the end-to-end connection of the steel wires can be ensured without affecting the normal running of the steel wires.

[0035] Optionally, the tray (first tray 2 or second tray 3) is an I-shaped wheel, comprising a cylindrical mounting portion and blocking portions provided at both ends of the mounting portion. The steel wire is wound around the mounting portion, and the blocking portions can limit the steel wire and prevent the steel wire from escaping from the mounting portion at one end.

[0036] When the steel wires are wound layer by layer on the material tray, the ends of the steel wires are usually pressed downwards. If the steel wires on the upper part are not released, the ends of the steel wires are difficult to pull out. Therefore, in one embodiment, only the steel wires on the standby material tray are wound around the accumulation and withdrawal wheel 20. After the head end of the steel wires on the standby material tray has passed through the accumulation and withdrawal wheel 20, it is connected to the end of the steel wires on the working material tray.

[0037] In other embodiments, if the end of the steel wire on the working reel can be pulled out, the end of the steel wire on the working reel can be passed around the accumulation and withdrawal wheel 20 and then connected to the head end of the steel wire on the standby reel. Alternatively, after a portion of the steel wire on the standby reel is passed around the accumulation and withdrawal wheel 20 and a portion of the steel wire on the working reel is also passed around the accumulation and withdrawal wheel 20, the head and tail ends of the two reels of steel wire are connected in the accumulation and withdrawal wheel 20. This application does not limit the source of the steel wire in the accumulation and withdrawal wheel 20.

[0038] Furthermore, when steel wire is wound on the wire-retracting wheel 20, n turns of steel wire are wound on the first wheel portion 21, and n turns of steel wire are also wound on the second wheel portion 22, n>0, and the steel wire wound around the first wheel portion 21 passes through the wire threading portion 23 and then around the second wheel portion 22. The winding direction of the steel wire on the first wheel portion 21 is opposite to the winding direction of the steel wire on the second wheel portion 22.

[0039] In this way, in the accumulation and withdrawal wheel 20, the same number of turns of steel wire are wound around the first wheel portion 21 and the second wheel portion 22, and the end of the steel wire in the wire threading portion 23 connected to the first wheel portion 21 and the end connected to the second wheel portion 22 are on the same side of the accumulation and withdrawal wheel 20. At the same time, the winding directions of the steel wires on the first wheel portion 21 and the second wheel portion 22 are opposite, which means that the steel wire in the wire threading portion 23 is neither continuously wound in the same direction as the steel wire in the first wheel portion 21 nor in the same direction as the steel wire in the second wheel portion 22.

[0040] Thus, the steel wire in the threading portion 23 is separated from the threading portion 23, and the steel wire in the accumulated wire wheel 20 can be released. Alternatively, the steel wire in the threading portion 23 is moved in the opposite direction of the wire winding, and the steel wire on the accumulated wire wheel 20 can also be gradually released.

[0041] In a specific embodiment, only the steel wire on the spare material tray is wound around the wire-receiving wheel 20. Figures 2 to 4 In this embodiment, a certain length of steel wire is first released from the spare material tray, and then the released steel wire is wound around the first wheel portion 21 clockwise for n turns. Next, the steel wire is passed through the wire threading portion 23. After the wire is supported by the wire threading portion 23, the steel wire is wound around the second wheel portion 22 counterclockwise for n turns. At this time, the end of the steel wire in the wire threading portion 23 connected to the first wheel portion 21 is used as the starting end of the steel wire winding, and the steel wire wound around the first wheel portion 21 is guided counterclockwise when looking towards the first wheel portion 21; the end of the steel wire in the wire threading portion 23 connected to the second wheel portion 22 is used as the starting end of the steel wire winding, and the steel wire wound around the second wheel portion 22 is also guided counterclockwise when looking towards the second wheel portion 22. When the steel wire on the working material tray is released to the end of the working steel wire and is pulled, the head end of the steel wire on the spare material tray is also pulled accordingly.

[0042] In the first embodiment, after the head end of the spare steel wire is pulled, the steel wire on the wire threading portion 23 is separated from the wire threading portion 23, and the steel wire wound on the accumulation and withdrawal wheel 20 loses support. Therefore, as the steel wire on the spare material tray continues to move forward, the steel wire on the accumulation and withdrawal wheel 20 is gradually pulled out.

[0043] In the second embodiment, after the head end of the spare steel wire is pulled, the threading portion 23 is rotated in the opposite direction of the steel wire winding, that is, Figures 2 to 4 As shown in the counterclockwise rotation, the wire threading portion 23 can gradually release the steel wire on the wire accumulation and withdrawal wheel 20, and the released steel wire is gradually pulled out as the head end is pulled.

[0044] It can be seen that since the number of wire coils on the first wheel portion 21 and the second wheel portion 22 is the same, the wire wound on the accumulation and withdrawal wheel 20 can be completely released. After the winding is completed, there is no wire on the accumulation and withdrawal wheel 20.

[0045] By providing a wire-retraction wheel 20 to wind the head end of the spare wire and the tail end of the working wire, the wire-retraction wheel 20 can support the head end of the spare wire and control the wire tension in conjunction with the wire's movement during reel changes. In particular, when the spare reel is transferred to the working station, the wire-retraction wheel 20 can pay out wire to compensate for the wire supply interruption when the spare reel is not in place, thereby preventing downstream equipment from being unable to continuously pull the wire.

[0046] With respect to the first embodiment described above, in order to facilitate the steel wire to be released from the threading portion 23, in one embodiment, the threading portion 23 is movable or deformable. Thus, when changing the reel, the threading portion 23 is moved or deformed to facilitate the steel wire on the threading portion 23 to be released from the threading portion 23, thereby achieving the release of the steel wire on the wire-retraction wheel 20.

[0047] For example, refer to Figure 3 The wire threading section 23 is a round rod with its left end connected to a drive (such as a pneumatic cylinder or electric cylinder) and its right end free. Normally, the rod is positioned above the first and second sheaves 21 and 22. The wire is wound clockwise around the first sheave 21 for n turns, then clockwise around the wire threading section 23, and finally counterclockwise around the second sheave 22 for n turns. During reel changes, the drive moves the wire threading section 23 from right to left, causing the wire on the wire threading section 23 to detach from the right end.

[0048] The present application does not limit the manner in which the steel wire is released from the wire threading portion 23 .

[0049] Optionally, n=1. This reduces the number of turns of the wire wrapped around the accumulating and withdrawing wheel 20, which is beneficial for controlling the tension of the wire belt and preventing the tension from getting out of control after the wire escapes from the wire threading portion 23 because a large amount of wire is no longer tensioned by the accumulating and withdrawing wheel 20.

[0050] Optionally, the wire-retracting wheel 20 is rotatably arranged on one side of the column 1; when the steel wire on the wire-retracting wheel 20 is pulled, the wire-retracting wheel 20 rotates to facilitate the movement of the steel wire arranged on the wire-retracting wheel 20.

[0051] Figure 1 In the illustrated embodiment, the wire-recessing wheel 20 is disposed at the top of the column 1, above the first wheel portion 21 and the second wheel portion 22. In other embodiments, the wire-recessing wheel 20 may also be disposed on any side of the column 1 or on the outside of the column 1, or below or to the side of the first wheel portion 21 and the second wheel portion 22, as long as it does not hinder the normal movement of the wire.

[0052] The wire-retraction wheel 20 is made rotatable. When the steel wire on the wire-retraction wheel 20 is pulled, the wire-retraction wheel 20 can reduce the friction between itself and the steel wire and guide the steel wire to move forward.

[0053] In order to prevent the wire-retracting wheel 20 from excessively rotating due to its own inertia and other factors when it is subjected to the reverse traction force of the wire, thereby affecting the wire running tension, the automatic conversion device for wire-retracting and wire-paying can optionally also include: a rotating shaft 4, on which the wire-retracting wheel 20 is rotatably arranged; a damping spring, which is arranged on the rotating shaft 4 and can provide friction damping for the wire-retracting wheel 20, which is beneficial to the rotation balance of the wire-retracting wheel 20.

[0054] In another embodiment, referring to Figure 1 and Figure 2 The wire-recessing wheel 20 also includes a connecting portion 24, which is arranged between the first wheel portion 21 and the second wheel portion 22; the wire threading portion 23 is arranged on the connecting portion 24, and an opening is provided on the wire threading portion 23; when the steel wire on the wire-recessing wheel 20 is pulled, the wire-recessing wheel 20 rotates, and when the wire threading portion 23 rotates to the point where the opening is facing downward, the steel wire in the wire threading portion 23 can escape from the wire threading portion 23 through the opening.

[0055] In the illustrated embodiment, the steel wire on the standby material tray is wound around the second wheel portion 22 and connected to the end of the steel wire on the working material tray. Therefore, the connecting portion 24 is preferably fixedly connected to the second wheel portion 22. When the standby steel wire is pulled, the second wheel portion 22 is subjected to the reverse force of the steel wire and rotates around the rotating shaft 4, driving the connecting portion 24 and the wire threading portion 23 to rotate accordingly. When the wire threading portion 23 rotates to the point where the opening faces downward, the steel wire in the wire threading portion 23 is able to detach from the wire threading portion 23 through the opening due to the weight of the steel wire and the downward traction force, thereby releasing the steel wire on the back-up wheel 20.

[0056] Optionally, in this embodiment, the first wheel portion 21 is fixedly connected to the second wheel portion 22. At this time, after the head end of the spare steel wire is pulled, the entire wire-receiving wheel 20 rotates synchronously.

[0057] Optionally, in this embodiment, the first wheel portion 21 and the second wheel portion 22 rotate independently. At this time, after the head end of the spare steel wire is pulled, the second wheel portion 22 drives the connecting portion 24 and the wire threading portion 23 to rotate synchronously, but will not affect the first wheel portion 21. The first wheel portion 21 will not rotate independently until the steel wire in the wire threading portion 23 is pulled and further drives the steel wire on the first wheel portion 21 to move forward.

[0058] For the above-mentioned second embodiment, in order to facilitate the rotation and wire release of the wire threading part 23, in one embodiment, the wire threading part 23 can rotate around the first wheel part 21 or the second wheel part 22; so that the wire threading part 23 rotates along the winding direction of the steel wire on the second wheel part 22, and can release the steel wire on the wire-recovery wheel 20.

[0059] In this embodiment, the threading portion 23 can be arranged outside the first material tray 2 or the second material tray 3; or, referring to Figure 4 In the illustrated embodiment, the wire-reduction wheel 20 further includes a rotating disk 25 disposed between the first wheel portion 21 and the second wheel portion 22; the wire threading portion 23 is disposed on the rotating disk 25. The rotating disk 25 is connected to a rotary drive member (such as a rotary cylinder, a motor, etc.). When the head end of the spare wire is pulled, the rotating disk 25 rotates in the opposite direction of the wire winding, driving the wire threading portion 23 to revolve around the axis of the rotating disk 25, thereby gradually releasing the wire from the wire-reduction wheel 20.

[0060] Figure 4 In the illustrated embodiment, the spare wire is wound around the second wheel 22 and then connected to the end of the working wire. The spare wire is first wound clockwise around the first wheel 21, passed through the wire threading portion 23 on the turntable 25, and then wound counterclockwise around the second wheel 22. When the accumulation and withdrawal wheel 20 unwinds the wire, the turntable 25 rotates counterclockwise, and the wire threading portion 23 drives the wire therein to revolve counterclockwise around the axis of the turntable 25. The wire in the wire threading portion 23 further drives the wires in the first and second wheel portions 21, 22 connected thereto to move counterclockwise, ultimately causing the wires in the first and second wheel portions 21, 22 to detach from their corresponding wheel portions.

[0061] Furthermore, in order to prevent the steel wire from being retained in the threading portion 23 after the steel wire on the wire wheel 20 is completely released, the threading portion 23 can be configured as a hook, or an opening can be provided on the threading portion 23 to facilitate the steel wire to eventually escape from the threading portion 23. Alternatively, the threading portion 23 can be configured as a clamping jaw. When the clamping jaw is closed, a channel is provided inside. When the steel wire is pulled, it can pass through the channel normally. When the clamping jaw is opened, the steel wire can escape from the threading portion 23. The present application does not limit the specific configuration of the threading portion 23, as long as it can guide the unwinding of the steel wire and can eventually cause the steel wire to escape.

[0062] Optionally, the first wheel portion 21 and / or the second wheel portion 22 are rotatably arranged on one side of the wire threading portion 23. The active rotation of the wire threading portion 23 does not interfere with the first wheel portion 21 and the second wheel portion 22, but when the steel wire on the first wheel portion 21 or the second wheel portion 22 is pulled, the first wheel portion 21 or the second wheel portion 22 can rotate to facilitate the advancement of the steel wire.

[0063] It should be explained that the pulling speed of the steel wire and the release speed of the steel wire on the wire-retraction wheel 20 are not only affected by the equipment operating parameters, but also by various factors during the actual operation of the equipment. Therefore, the tension of the steel wire needs to be controlled in real time.

[0064] Optionally, the automatic conversion device for accumulated and withdrawn wire also includes: a first wire clamping mechanism 30 for fixing the steel wire between the spare material tray and the accumulated and withdrawn wire wheel 20; and / or a second wire clamping mechanism 40 for fixing the steel wire between the working material tray and the accumulated and withdrawn wire wheel 20.

[0065] During the normal wire feeding process of the working material disc, the end of the working steel wire and the head end of the spare steel wire need to be in a relatively fixed state. In this way, the steel wire on the wire-retracting wheel 20 can be prevented from affecting the normal movement of the working steel wire, and the steel wire that has not been pulled out on the spare material disc can be ensured not to affect the feeding of the steel wire on the wire-retracting wheel 20 when changing the roll.

[0066] By setting up the first wire clamping mechanism 30, the end of the steel wire in the wire-receiving wheel 20 connected to the spare material tray can be fixed, thereby ensuring that the state of the steel wire on the spare material tray is stable and the entire reel of steel wire will not become loose due to the first end being pulled out.

[0067] Specifically, after a certain length of steel wire is pulled out from the spare material tray, the steel wire is first wound around the first wheel portion 21, and then the steel wire between the first wheel portion 21 and the spare material tray can be fixed by the first wire clamping mechanism 30, thereby preventing the steel wire in the spare material tray from being further pulled out or becoming derailed. Of course, after a certain length of steel wire is pulled out from the spare material tray, the portion between the steel wire and the spare material tray can be fixed by the first wire clamping mechanism 30. Alternatively, after the spare steel wire is wound around the back-up wire wheel 20, the steel wire between the back-up wire wheel 20 and the spare material tray can be fixed by the first wire clamping mechanism 30.

[0068] Optionally, in order to avoid the steel wire in the standby material tray being pulled when the steel wire in the accumulation and withdrawal wheel 20 is pulled during the reel change process, the first wire clamping mechanism 30 clamps the steel wire until the reel change is completed, the steel wire is completely separated from the accumulation and withdrawal wheel 20, and the standby material tray reaches the work station, and the first wire clamping mechanism 30 releases the steel wire so that the standby material tray can be converted into a new working material tray and start normal wire feeding.

[0069] By providing the second wire clamping mechanism 40, the end of the steel wire in the accumulation and withdrawal wheel 20 connected to the working material tray can be fixed, thereby ensuring that the state of the steel wire on the working material tray is stable.

[0070] Specifically, the head end of the spare steel wire is wound around the wire-retracting wheel 20 and connected to the end of the working steel wire. Subsequently, the steel wire between the wire-retracting wheel 20 and the working material tray is clamped by the second wire clamping mechanism 40, thereby preventing the working material tray from affecting the steel wire in the wire-retracting wheel 20 during the wire-releasing process, or preventing the wire-retracting wheel 20 from incorrectly releasing the wire, affecting the normal wire-releasing of the working material tray, or affecting the wire running tension.

[0071] Different from the first wire clamping mechanism 30, when the end of the working wire is or is about to be pulled, the second wire clamping mechanism 4 needs to release the wire immediately so that the wire-retracting wheel 20 can cooperate with the wire release and realize the reel change.

[0072] Optionally, the first wire clamping mechanism 30 and / or the second wire clamping mechanism 40 adopts a clamping claw, including two clamping pieces and a clamping drive (such as an air claw, a cylinder, etc.). The clamping drive can drive the two clamping pieces closer to each other to clamp and fix the steel wire, or the clamping drive can drive the two clamping pieces away from each other to release the steel wire.

[0073] Optionally, the first wire clamping mechanism 30 and / or the second wire clamping mechanism 40 adopts an electromagnet. When powered on, the electromagnet can attract the steel wire and then fix the steel wire. When the power is turned off, the steel wire is released.

[0074] Optionally, the first wire clamping mechanism 30 and / or the second wire clamping mechanism 40 adopts a manual clamp. The operator acts on the manual clamp to open the manual clamp to facilitate inserting or removing the steel wire. After the operator releases the manual clamp, the manual clamp can clamp the steel wire.

[0075] The present application does not limit the specific configurations of the first wire clamping mechanism 30 and the second wire clamping mechanism 40 .

[0076] Furthermore, the automatic conversion device for accumulation, withdrawal and pay-off of wire provided in the present application also includes a rotary drive mechanism 10 for driving the column 1 to rotate so that the first material tray 2 and the second material tray 3 alternately reach the working station.

[0077] At this time, the material tray at the working station is the working material tray. The wire is released after the material tray reaches the unified working station, so that the released wire has a unified wire path, which further facilitates the normal operation of downstream equipment.

[0078] Figure 1In the embodiment shown, only a first material tray 2 and a second material tray 3 are provided on the column 1, and the two material trays are arranged opposite to each other. When changing the coil, the rotary drive mechanism 10 drives the column 1 to rotate 180° so that the spare material tray can reach the working station and be converted into a new working material tray. At this time, the original working material tray rotates to the loading and unloading station to rewind the steel wire, or the empty material tray is replaced with a new material tray filled with steel wire, so that the loading and unloading station is reconfigured with a spare material tray. After the new working material tray completes the wire laying, the rotary drive mechanism 10 drives the column 1 to continue rotating 180°, or the rotary drive mechanism 10 drives the column 1 to rotate 180° in the opposite direction, so that the positions of the two material trays can be alternated again, so that one of the material trays is in the working station to lay the wire, and the other material tray is in the loading and unloading station to reconfigure the spare material tray.

[0079] In other embodiments, three or more material trays are provided on the column 1, with the multiple material trays being evenly spaced along the circumference. When three material trays are provided on the column 1, the rotary drive mechanism 10 drives the column 1 to rotate 120° at a time. When four material trays are provided on the column 1, the rotary drive mechanism 10 drives the column 1 to rotate 90° at a time, and so on.

[0080] The rotary drive mechanism 10 may be a rotary drive component such as a rotary cylinder or a motor.

[0081] A specific implementation method, refer to Figure 1 The rotation drive mechanism 10 includes: a base 11, on which the column 1 is rotatably arranged; a driving cylinder 12, which is swingably arranged on a mounting frame 13; a first connecting rod 14, which is connected to the piston rod of the driving cylinder 12; a second connecting rod 15, which connects the column 1 and the first connecting rod 14; wherein, the base 11 and the mounting frame 13 are fixedly arranged, the first connecting rod 14 is rotatably connected to the second connecting rod 15, and when the piston rod of the driving cylinder 12 makes a linear motion, the rotation of the column 1 can be achieved through the rotation of the second connecting rod 15 and the swing of the driving cylinder 12.

[0082] Optionally, a support rod is provided on the base 11, and the column 1 is rotatably sleeved on the outside of the support rod through a bearing; the base 11 and the mounting frame 13 are fixedly arranged on the same work platform.

[0083] It is easy to understand that the piston rod of the driving cylinder 12 can only perform linear motion, while the column 1 performs rotational motion. The movement directions of the two are not uniform and need to be compensated. Therefore, by the rotational connection between the first connecting rod 14 and the second connecting rod 15, when the first connecting rod 14 performs linear motion, it can provide the second connecting rod 15 with a force to the left or right, and the second connecting rod 15 further applies force to the column 1; because the column 1 can only rotate on its own, the second connecting rod 15 will also revolve around the axis of the column 1 while moving to the left or right; when the second connecting rod 15 revolves, it drives the first connecting rod 14 to rotate in the opposite direction, causing the driving cylinder 12 to swing relative to the mounting frame 13. Through the rotation of the two connecting rods 15 and the swinging of the driving cylinder 12, the direction difference between the linear motion and the rotational motion is compensated in both directions, so as to achieve stable rotation of the column 1.

[0084] Optionally, to ensure that the material tray stays accurately at the working station or the loading and unloading station, a first stop is provided at the working station and / or the loading and unloading station, and a second stop is provided on the column 1. When the column 1 rotates until the first stop contacts the second stop, the first stop can prevent the second stop from continuing to move, thereby ensuring that the column 1 reaches the preset position.

[0085] Furthermore, the automatic conversion device for accumulated and withdrawn wires provided in the present application also includes a detection mechanism 50 for detecting whether the steel wire on the accumulated and withdrawn wire wheel 20 has been fully paid out, so as to confirm whether the reel change is completed.

[0086] The detection mechanism 50 may be a photoelectric sensor. The photoelectric sensor may be disposed on the wire path of the wire in the accumulation and withdrawal wheel 20. When the wire in the accumulation and withdrawal wheel 20 is completely released and no wire is left on the wire path, the photoelectric sensor can detect that there is no wire in the accumulation and withdrawal wheel 20. Alternatively, the photoelectric sensor may be disposed in the accumulation and withdrawal wheel 20 to detect whether there is wire on the accumulation and withdrawal wheel 20.

[0087] Alternatively, the detection mechanism 50 may be a CCD camera (charge coupled device), which can directly detect whether there is steel wire on the wire accumulation and withdrawal wheel 20 by taking pictures.

[0088] The following details a specific workflow, refer to Figure 1, the working material tray (in the illustrated embodiment, the first material tray 2 set on the right is the working material tray) at the working station releases the wire until the end of the steel wire on it is pulled, and the second wire clamping mechanism 40 loosens the wire between the accumulation and withdrawal wheel 20 and the working material tray, and the wire in the accumulation and withdrawal wheel 20 is pulled, and the accumulation and withdrawal wheel 20 rotates, driving the wire threading part 23 to rotate. At the same time, the rotation drive mechanism 10 drives the column 1 to rotate; after the opening of the wire threading part 23 faces downward, the wire detaches from the wire threading part 23 from the opening, and the wire on the accumulation and withdrawal wheel 20 is gradually pulled out, and the accumulation and withdrawal wheel 20 releases the wire to regulate the tension of the wire during the movement of the spare material tray (in the illustrated embodiment, the second material tray 3 set on the left is the spare material tray) to the working station; when the detection mechanism 50 cannot detect the wire, the spare material tray arrives at the working station and becomes the new working material tray; the first wire clamping mechanism 30 loosens the wire between the spare material tray and the accumulation and withdrawal wheel 20, so that the wire on the spare material tray can be released normally. Manually adjust the wire wheel 20 to reset so that the opening of the wire threading part 23 faces upward. When the empty material tray arrives at the loading and unloading station, a new spare material tray is replaced, and a certain length of steel wire is pulled out and wound around the wire wheel 20, so that the head end of the spare steel wire is connected to the end of the working steel wire.

[0089] The automatic conversion device for accumulation, withdrawal and pay-off of wire provided in the present application further includes a traction device 60 for advancing the traction wire.

[0090] Since the automatic conversion device for accumulating, withdrawing and paying off wire provided in the present application enables the wire to be automatically changed, the traction device 60 can continuously perform traction work to facilitate continuous operation of the equipment.

[0091] Specifically, when the steel wire on the working material tray is released, the end of the working steel wire is pulled by the traction device 60, which further pulls the steel wire on the accumulation and withdrawal wheel 20. As the accumulation and withdrawal wheel 20 gradually releases the wire, the steel wire can be transported stably until the spare material tray moves to the working station and is converted into a new working material tray.

[0092] The traction device 60 may be a clamping claw that can clamp the steel wire at the front end, and then pull the steel wire forward continuously to reach the downstream processing station.

[0093] Due to the large mass of the material tray, it is difficult to rotate the material tray and actively release the steel wire. For this reason, in one embodiment, the traction device 60 includes: a swing arm 61, on which a guide wheel 62 is provided, and the steel wire is wound around the guide wheel 62; a counterweight block 63, which is arranged on both sides of the turntable 64 opposite to the swing arm 61; a rotating mounting seat 65, on which the turntable 64 is rotatably provided; when the steel wire travels, the swing arm 61 performs a circular motion around the working material tray.

[0094] For details, please refer to Figure 1Two guide wheels 62 are provided on the swing arm 61. The steel wire passes through the guide wheels 62 in sequence and goes downstream. The guide wheels 62 can support and tension the steel wire to ensure the stability of the steel wire unwinding. The guide wheels 62 can also guide the running direction of the steel wire so that the steel wire can move along the preset route.

[0095] Optionally, a guide block 66 is further provided on the swing arm 61, and a guide channel is provided in the guide block 66. After the steel wire passes through the guide channel and leads to the downstream, the guide block 66 can further adjust the running direction of the steel wire and also has the function of smoothing and straightening.

[0096] When the steel wire passes through the swing arm 61 , the swing arm 61 will be subjected to the reverse force of the steel wire. Therefore, a counterweight block 63 opposite to the swing arm 61 is provided on the turntable 64 to facilitate the rotation and balance of the swing arm 61 .

[0097] Since the turntable 64 is rotatably arranged on the rotating mounting seat 65, when the steel wire travels, the tension on the steel wire acts in the opposite direction on the swing arm 61, so that the swing arm 61 has a tendency to move, and the swing arm 61 drives the turntable 64 to move. The turntable 64 is restricted by the connection between itself and the rotating mounting seat 65 and can only perform rotational movement. At the same time, the counterweight block 63 can balance the force on the turntable 64, preventing the swing arm 61 from always staying below the turntable 64.

[0098] Optionally, the swing arm 61 is arranged at the edge of the turntable 64, away from the rotation axis of the turntable 64. Thus, the swing arm 61 can perform revolution around the rotation axis, thereby performing circular motion around the working material tray, and then taking out the steel wire from the working material tray in circles.

[0099] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
