Abstract
Description
Technical Field
[0001] This application relates to the field of steel plate processing equipment technology, and in particular to an automatic flipping device for flipping steel plates and having a horizontal centering function. Background Technology
[0002] In the steel plate processing, it is often necessary to flip the steel plates for double-sided processing or inspection. Currently, commonly used steel plate flipping equipment mainly employs the following two methods:
[0003] Overhead crane lifting and flipping: This method uses overhead cranes and electromagnetic chucks to lift and flip the steel plate. It is inefficient, poses significant safety hazards, and makes precise positioning of the steel plate difficult.
[0004] Specialized flipping machine: This type of machine uses a fixed flipping mechanism, with a hydraulic cylinder or motor driving the flipping arm to flip the steel plate. While this method is highly efficient, it typically lacks the ability to horizontally center the steel plate, making it difficult to meet the demands of high-precision processing. Utility Model Content
[0005] This utility model provides an automatic flipping device for turning steel plates and having a horizontal centering function to overcome the shortcomings of the prior art. By setting a set of flipping arms with movable hooks on both sides of the flipping shaft, the centering effect of turning the steel plate is increased.
[0006] An automatic flipping device for steel plate flipping with horizontal centering function, according to the present invention, includes:
[0007] The frame, with its upper surface horizontal, is used to support the conveying mechanism and the tilting mechanism;
[0008] The conveying mechanism includes conveying rollers arranged parallel to the frame, wherein the axial direction of the conveying rollers is perpendicular to the conveying direction of the steel plate;
[0009] The flipping mechanism includes a flipping shaft and a flipping arm. The flipping shaft is parallel to the steel plate conveying direction. There are two flipping shafts. One end of each flipping arm has a pivot hole, which is rotatably connected to the flipping shaft via a bearing. Each flipping shaft is connected to two or more flipping arms. The flipping arms are positioned in the gap between the conveying rollers and are equipped with hooks.
[0010] The control system includes a PLC controller and a hook surface sensor. The hook surface sensor is located on the protruding section of the hook. The PLC controller is connected to the tilting arm, the hook, and the hook surface sensor.
[0011] In one embodiment, the system further includes hydraulic cylinders and a hydraulic pump station unit. One end of the hydraulic cylinder is connected to the tilting arm, and the other end is hinged to the frame. The hydraulic cylinder is used to drive the tilting arm to rotate around the tilting axis. All hydraulic cylinders are connected to the hydraulic pump station unit.
[0012] In one embodiment, the flipping angle between the flipping arm and the upper surface of the frame is 0-95°.
[0013] In one embodiment, the spacing between adjacent flip arms connected to the same flip axis is the same, and the flip arms connected to different flip axes are symmetrically arranged.
[0014] In one embodiment, the tilting arm further includes a lead screw, a slide block, and a drive motor. The lead screw is in the same direction as the length of the tilting arm and is fixedly disposed on the side of the tilting arm. The slide block cooperates with the lead screw, the hook is fixedly connected to the slide block, and the drive motor drives the lead screw to rotate.
[0015] Furthermore, the hook is an L-shaped hook, including a horizontal section and a vertical section. The horizontal section is used to hook the edge of the steel plate, and the vertical section is fixedly connected to the slide.
[0016] In one embodiment, the control system further includes an angle encoder disposed at one end of the flipping shaft for detecting the rotation angle of the flipping arm.
[0017] In one embodiment, the control system further includes a position encoder disposed on the tilting arm for detecting the position of the hook.
[0018] Compared with the prior art, the advantages of this utility model are as follows:
[0019] (1) The flipping arm of this application is provided with a screw slide hook mechanism. The hook hooks the edge of the steel plate and can slide along the flipping arm to adjust the position of the steel plate so that it is centered.
[0020] (2) The symmetrically arranged tilting arms on both sides of this application are hydraulically driven, and the tilting arms on the same side are spaced at the same distance, so the tilting plate is stable and efficient.
[0021] (3) This application uses a PLC controller to automatically calculate and detect the position of the steel plate and hook and the load-bearing capacity of the hook, so as to realize the automatic flipping and horizontal centering of the steel plate. The operation is simple, safe and reliable. Attached Figure Description

[0030] Example 1
[0031] An automatic flipping device for steel plates with horizontal centering function, see reference. Figure 1 , Figure 1 A schematic diagram of the overall structure of the device is shown, including:
[0032] Frame 1, with its upper surface horizontal, is used to support the conveying mechanism and the tilting mechanism;
[0033] The conveying mechanism includes a conveying roller 2 arranged parallel to the frame 1, the axial direction of the conveying roller 2 being perpendicular to the steel plate conveying direction;
[0034] The flipping mechanism includes a flipping shaft 3 and a flipping arm 4. The flipping shaft 3 is parallel to the steel plate conveying direction. There are two flipping shafts 3. One end of the flipping arm 4 is provided with a rotating shaft hole 44. The rotating shaft hole 44 is rotatably connected to the flipping shaft 3 through a bearing. Each flipping shaft 3 is connected to five flipping arms 4. The flipping arms 4 are set in the gap between the conveying rollers 2. The flipping arms 4 are provided with hooks 5.
[0035] The control system includes a PLC controller and a hook surface sensor. The hook surface sensor is located on the horizontal section 51 of the hook 5. The PLC controller is connected to the hook surface sensor, the tilting arm 4, and the hook 5.
[0036] In this embodiment, a hydraulic cylinder 6 and a hydraulic pump station unit 7 are also included. One end of the hydraulic cylinder 6 is connected to the tilting arm 4 and the other end is hinged to the frame 1. It is used to drive the tilting arm 4 to rotate around the tilting shaft 3. All hydraulic cylinders 6 are connected to the hydraulic pump station unit 7.
[0037] In this embodiment, the flipping angle between the flipping arm 4 and the upper surface of the frame 1 is 0-95°.
[0038] In this embodiment, the spacing between adjacent flip arms 4 connected to the same flip axis 3 is the same, and the flip arms 4 connected to different flip axes 3 are symmetrically arranged.
[0039] like Figure 2 As shown, the tilting arm 4 also includes a lead screw 41, a slide block 42, and a drive motor 43. The lead screw 41 is in the same direction as the tilting arm 4 and is fixedly installed on the side of the tilting arm 4. The slide block 42 cooperates with the lead screw 41, and the hook 5 is fixedly connected to the slide block 42. The drive motor 43 drives the lead screw 41 to rotate. Specifically, the lead screw 41 is installed inside the slide block 42, and the slide block 42 matches the lead screw 41. When the lead screw 41 rotates, the slide block 42 runs along the lead screw 41.
[0040] Furthermore, the hook 5 is an L-shaped hook 5, including a horizontal section 51 and a vertical section 52. The horizontal section 51 is used to hook the edge of the steel plate, and the vertical section 52 is fixedly connected to the slide 42.
[0041] In this embodiment, the control system also includes an angle encoder 8, which is disposed at one end of the flip shaft 3 and is used to detect the rotation angle of the flip arm 4.
[0042] In this embodiment, the control system also includes a position encoder, which is mounted on the tilting arm 4 and is used to detect the position of the hook 5.
[0043] When this embodiment is run:
[0044] (1) Both the initial side flipping arm 4 and the receiving side flipping arm 4 are kept horizontal. Input the steel plate width data in the PLC controller and place the steel plate to be flipped on the initial side flipping arm 4.
[0045] (2) The PLC controller calculates the positioning stroke of the hook 5 based on the width of the steel plate and the position of the steel plate detected by the sensor, drives the motor 43 to work, drives the slide 42 and the hook 5 to move on the lead screw 41, hooks the edge of the steel plate and drags it to the center position.
[0046] (3) The PLC controller controls the hydraulic cylinder 6 to drive the initial side flipping arm 4 to flip the steel plate 85-87°. At the same time, the receiving side flipping arm 4 rotates to fit with the steel plate, and the receiving side hook 5 runs to hook the bottom edge of the steel plate. The initial side hook 5 retracts 1-2cm and disengages from the edge of the steel plate.
[0047] (4) The two sides of the rotating arms 4 rotate 5-10° to the receiving side simultaneously, so that the steel plate support surface is transferred from the initial side to the receiving side.
[0048] (5) The side-turning arm 4 rotates to the horizontal position, and the drive motor 43 drives the hook 5 to move on the lead screw 41, so that the steel plate is in the center position. At the same time, the initial side-turning arm 4 rotates to the original position, and the steel plate is centered and turned into place.
[0049] (6) The hydraulic cylinder 6 stops working, the hook 5 returns to the zero position, and the steel plate is conveyed out of the flipping machine table through the conveying roller 2.
[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
