Description

Technical Field

[0001] This invention relates to the technical field of I-beam reel take-up devices, specifically to a dual-station automatic reel-changing take-up device and method thereof. Background Technology

[0002] In the production of steel wire products or other metal wires, the processed wire is mostly collected by using I-beam reels. Once the I-beam reels are full, the machine needs to be stopped and manual operation is required to replace the full and empty reels.

[0003] Especially for products with high quality requirements for steel wire products, stopping the machine to change the reel makes it impossible to achieve continuity in the steel wire processing, which has a great impact on the quality of the steel wire and also increases a lot of labor costs. In addition, the loading and unloading of the I-beam reel requires machine shutdown, which greatly reduces production efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned background technology and provide a dual-station automatic reel changing and take-up device and method. This device can quickly switch the steel wire between a full reel and an empty reel, improve product production efficiency, and avoid the impact of stopping to change reels on the quality of the steel wire.

[0005] To achieve the above objectives, the present invention provides a dual-station automatic reel-changing and take-up device, comprising a frame on which two I-beams are mounted. A wire-cutting device is installed on the flange of each of the two I-beams, and a wire-pushing device is located above the two I-beams. When one of the two I-beams is fully wound with wire, the wire-pushing device pushes the wire to the empty I-beam of the other reel and causes the wire to slide into the wire-cutting device. The wire is then cut by the wire-cutting device and wound back onto the empty I-beam for take-up.

[0006] Furthermore, the wire-cutting device includes a clamping bracket, in which a first blade is installed. The first blade is hinged to both sides of the clamping bracket via a mounting shaft. A second blade that cooperates with the first blade is provided on the clamping bracket. A cylinder for driving the first blade to rotate is provided above the first blade. The first blade can rotate around the mounting shaft under the action of the cylinder to cooperate with the second blade to cut the steel wire.

[0007] Furthermore, the first blade has an L-shaped structure with a hook-shaped cutting edge, and a blade shank is provided above the first blade. The upper end of the blade shank is connected to the cylinder for transmission, and the lower end of the blade shank is fixedly connected to the first blade.

[0008] Furthermore, the dual-station automatic reel-changing take-up device also includes a wire feeding device for adjusting the wire feeding position, the wire feeding device being disposed above the frame.

[0009] Furthermore, a wire laying device is provided above the I-beam reel. The wire laying device is parallel to the axis of the I-beam reel. When the I-beam reel is winding up the wire, the wire laying device is adjusted to move so that the steel wire is evenly distributed on the surface of the I-beam reel.

[0010] Furthermore, a wire-blocking device is provided between the two I-beams. When the I-beams need to be replaced, the wire-blocking device pushes the wire toward one side of the I-beam parallel to the axis of the I-beam until the wire slides into the wire-breaking device.

[0011] Furthermore, a fixed ejector pin and a movable ejector pin are respectively provided on both sides of the I-beam wheel. The fixed ejector pin is installed in the shaft hole of the frame and is driven to rotate the I-beam wheel by a drive device provided on the same side. The movable ejector pin is installed in the shaft hole of the frame on the opposite side of the fixed ejector pin and is used to lock and release the I-beam wheel between the fixed ejector pin and the movable ejector pin.

[0012] Furthermore, the I-beam wheel is provided with a flange on the side of the fixed ejector pin, and the wire breaking device is installed on the flange on the side of the fixed ejector pin.

[0013] Furthermore, a movable trolley device is provided below the I-beam wheel. When the movable ejector pin is retracted, the movable trolley device drives the I-beam wheel to move towards the movable ejector pin side, disengaging the I-beam wheel from the fixed ejector pin.

[0014] Furthermore, the side of the I-beam reel is provided with an I-beam reel ejection device, which is driven by a cylinder to eject the I-beam reel after the winding is completed from the winding machine.

[0015] The present invention also provides a method for changing reels and taking in wire using the above-mentioned device, comprising the following steps: when a reel is fully wound with wire and it is necessary to change the wire to another empty reel, the wire laying device moves to the edge of the empty reel, and the wire pushing device moves the wire between the wire laying device and the reel to one side of the empty reel. At the same time, the wire blocking device moves to the outer side of the flange on the fixed pin side of the empty reel, and cooperates with the wire pushing device to push the wire into the wire breaking device. At this time, the empty reel rotates, and the wire breaking device drives the first blade to rotate through the cylinder. The first blade and the second blade cooperate to cut the wire and clamp it. The empty reel continues to rotate to complete the take-up operation.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] Firstly, the dual-station automatic reel-changing and take-up device of the present invention has good versatility, which can improve product production efficiency and avoid the impact of stopping to change reels on the quality of steel wire. The steel wire is cut by the cooperation of the first and second blades of the wire cutting device, which quickly achieves the switching of steel wire between a full reel and an empty reel.

[0018] Secondly, the present invention has a dual-station automatic reel take-up mechanism, which is particularly suitable for the automatic take-up of wires with larger diameter or higher strength. Through the coordinated action of the wire blocking device, the wire pushing device and the wire breaking device, it can achieve rapid wire breaking on a full reel and stable take-up on an empty reel, thus achieving the purpose of rapid switching between take-up of steel wire on a full reel and an empty reel.

[0019] Thirdly, the dual-station automatic reel changing and take-up device of this invention does not require manual operation for reel changing, realizing the replacement of take-up reels without stopping the machine, saving labor costs and improving product quality and production efficiency.

[0027] The following examples illustrate the implementation of the present invention in detail, but they do not constitute a limitation on the invention and are merely illustrative. Furthermore, the advantages of the present invention will become clearer and easier to understand by explaining them.

[0028] like Figures 1-3The illustrated dual-station automatic reel take-up device includes a frame 1 with two I-beams 2 mounted on it. A wire-cutting device 3 is installed on the flange of each I-beam 2, and a wire-pushing device 4 is installed above each I-beam 2. When one of the I-beams 2 is fully wound with wire, the wire-pushing device 4 pushes the wire to the empty I-beam of the other reel and drives the wire to slide into the wire-cutting device 3. The wire-cutting device 3 cuts the wire 13 and then winds it back into the empty I-beam for take-up.

[0029] like Figure 2 and Figure 3 As shown, a wire feeding device 5 is installed above the frame 1, which is used to adjust the position of the steel wire entering the machine. A wire laying device 6 is installed above the I-beam spool 2, and the wire laying device 6 is parallel to the axis of the I-beam spool 2. When the I-beam spool 2 is winding the wire, the wire laying device 6 is adjusted to move so that the steel wire is evenly distributed on the surface of the I-beam spool. In this embodiment, the wire laying device 6 is installed between the two I-beam spools above the frame 1. The motor in the wire laying device 6 drives the lead screw to rotate, so that the wire guide wheel moves at a constant speed, and the steel wire is evenly wound onto the surface of the I-beam spool. When the steel wire on one I-beam spool is full and it is necessary to change the steel wire to another empty I-beam spool, the push wheel of the wire laying device 6 moves to the edge of the I-beam spool and the push device 4 moves the steel wire between the wire laying device 6 and the I-beam spool to the side of the empty I-beam spool. At the same time, the empty I-beam spool rotates, and then the wire is pushed into the wire breaking device 3 by the wire blocking device 7.

[0030] like Figure 2 and Figure 3 As shown, a wire-blocking device 7 is also provided between the two I-beams 2. When the I-beams need to be reeled, the wire-blocking device 7 pushes the wire towards one side of the I-beam parallel to the I-beam axis until the wire slides into the wire-breaking device 3. When the wire is pushed to the other I-beam side, the wire-blocking device 7 moves the wire-blocking block to the outside of the large flange in the fixed pin 8 device through a cylinder to assist the wire in entering the wire-breaking device 3. In this embodiment, the wire-blocking device 7 is installed in the middle position of the two I-beams on the frame 1, and is equipped with a cylinder device, which can realize the forward and backward displacement of the wire-blocking device. When the I-beams need to be reeled, the wire-blocking device 7 pushes the wire towards the empty reel I-beam parallel to the I-beam axis, so that the wire can slide into the wire-breaking device. After the empty reel I-beam is wound with wire, it retracts.

[0031] like Figure 2As shown, a moving trolley device 11 is provided below the I-beam 2. When the movable ejector pin 9 retracts, the moving trolley device 11 drives the I-beam 2 to move towards the movable ejector pin 9, disengaging the I-beam 2 from the fixed ejector pin 8. In this embodiment, two moving trolley devices 11 are respectively installed on the frame 1 directly below the two I-beams. The moving trolley devices are pushed by the extension and retraction of the cylinder, causing the I-beams to move back and forth, pushing the I-beams out of the ejector pin head for easy unloading. An I-beam 2 ejection device 12 is provided on the side of the I-beam 2. The I-beam 2 ejection device 12 is driven by a cylinder to push the I-beam 2, which has completed winding, out of the winding machine. In this embodiment, the I-beam 2 ejection device 12 is installed at the middle base plate of the frame 1 and is driven by a cylinder to swing the push plate, pushing the I-beam 2, which needs to be unloaded, out of the winding machine.

[0032] like Figure 4 As shown, a fixed ejector pin 8 and a movable ejector pin 9 are respectively provided on both sides of the I-beam spool 2. The fixed ejector pin 8 is installed in the shaft hole of the frame and is connected to the drive device 10, which is located on the same side, via belt drive to drive the I-beam spool to rotate. A flange is provided on the side of the I-beam spool located on the fixed ejector pin, and the wire breaking device is installed on the flange located on the side of the fixed ejector pin. The movable ejector pin 9 is installed in the shaft hole of the frame on the opposite side of the fixed ejector pin 8. The movable ejector pin 9 is driven by a cylinder to move, so that the I-beam spool is fixed between the fixed ejector pin 8 and the movable ejector pin 9, which is used to lock and release the I-beam spool between the fixed ejector pin 8 and the movable ejector pin 9. The drive device 10 is installed on the side of the frame located on the fixed ejector pin 8 and is connected to the drive shaft of the fixed ejector pin 8 via a belt to provide driving force for the I-beam spool to take up the wire. The drive device 10 contains two independent drive units, which can provide driving force for the two I-beam spools respectively.

[0033] like Figure 5 As shown, the wire-cutting device 3 includes a clamping bracket 3.1, in which a first blade 3.2 is installed. The first blade 3.2 is hinged to both sides of the clamping bracket 3.1 via a mounting shaft. A second blade 3.3, which works in conjunction with the first blade 3.2, is mounted on the clamping bracket 3.1. A cylinder 3.4 is mounted above the first blade 3.2 to drive its rotation. Under the action of the cylinder 3.4, the first blade 3.2 can rotate around the mounting shaft and work with the second blade 3.3 to cut the wire. The first blade 3.2 has an L-shaped structure with a hook-shaped cutting edge 3.21. A blade shank 3.5 is also mounted above the first blade 3.2. The upper end of the blade shank 3.5 is connected to the cylinder 3.4 for transmission, and the lower end of the blade shank 3.5 is fixedly connected to the first blade 3.2. In this embodiment, the wire breaking device 3 is installed at the edge of the large flange of the I-beam wheel located on the fixed pin. When the wire enters or exits the wire breaking device, the cylinder extends and retracts to drive the cutter bar 3.5 and the first blade 3.2 to rotate. The first blade and the second blade cooperate to cut the wire. After the wire is broken, the wire breaking device can clamp the wire and fix the wire on the bottom diameter of the I-beam wheel when the I-beam wheel rotates.

[0034] The present invention provides a method for changing reel and taking up wire using the aforementioned device, comprising the following steps: Figure 6 As shown, when a steel wire is fully wound on one spool and needs to be transferred to another empty spool, the wire feeding device 6 moves to the edge of the empty spool. The wire pushing device 4 moves the steel wire between the wire feeding device 6 and the spool to one side of the empty spool. At the same time, the wire blocking device moves to the outer side of the flange on the fixed pin side of the empty spool, and works with the wire pushing device to push the steel wire into the wire breaking device. At this time, the empty spool rotates, and the wire breaking device 3 drives the first blade 3.2 to rotate through the cylinder 3.4. The first blade 3.2 and the second blade 3.3 work together to cut the steel wire and clamp it. The empty spool continues to rotate to complete the winding work.

[0035] The dual-station automatic reel-changing take-up device provided by this invention can switch the steel wire between two reels without stopping the machine. In particular, it can quickly cut the steel wire during automatic reel changing when taking up coarse or high-strength steel wire, which can avoid the impact on the quality of steel wire when the machine stops and starts repeatedly and improve production efficiency.

[0036] The above are merely specific embodiments of the present invention. It should be noted that any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the protection scope of the present invention. Any other aspects not described in detail are prior art.
