Description

Technical Field

[0001] This utility model relates to the field of zinc sheet conveying line technology, specifically to a continuous turnover and transportation device for zinc sheets. Background Technology

[0002] In the zinc smelting process, zinc sheet stacks produced by the zinc stripping unit in the electrolytic workshop need to be transported to the finished product warehouse and the zinc induction furnace charging unit and bypass conveyor in the slag treatment workshop. The project involves a large amount of transportation. In view of the current demand for automation and mechanization in China, a fully automated zinc sheet stack transfer and ingot casting production line is required to minimize the amount of zinc sheet stack transfer operations and manual labor.

[0003] Because continuous transportation across workshops is involved, the conveyor line often needs to turn. In the traditional conveying process, an arc-shaped conveyor line is often set up at the turning point to complete the turning. However, the arc-shaped conveyor line usually requires a large turning radius, has a large space requirement, has high requirements for the spatial layout of the workshop, has poor layout flexibility, and is difficult to arrange in narrow or long workshop corridors. Therefore, it is difficult to meet the requirements for turning of the conveying path under this working condition.

[0004] Therefore, it is necessary to study a continuous turnover and transportation device for zinc sheets. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a continuous turnover and transportation device for zinc sheets, which can effectively solve the problem that existing arc-shaped reversing conveyor lines are difficult to arrange in narrow workshop transport corridors.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The first and second sections of the conveyor line are arranged perpendicularly.

[0009] The turnover conveyor line is located between the end point of section one of the conveyor line and the beginning point of section two of the conveyor line;

[0010] The turnover conveyor line includes a reversing conveyor section and an electric rotating base;

[0011] The reversing conveyor section is mounted on an electric rotating base and can be rotated by the electric rotating base to be coaxial with either section one or section two of the conveyor line.

[0012] The end point of the first section of the conveyor line, the starting point of the second section of the conveyor line, and the middle section of the reversing conveyor line are respectively equipped with a first passing detection unit, a second passing detection unit, and a third passing detection unit to obtain the position information of the passing zinc sheet stacks.

[0013] The first pass detection unit, the second pass detection unit, the third pass detection unit, and the electric rotating base are all connected to the controller.

[0014] Furthermore, the first section of the conveyor line, the second section of the conveyor line, and the reversing conveyor section all include a chain conveyor mechanism; the chain conveyor mechanism includes a frame, a load-bearing beam, a rotating shaft, a sprocket, and a ring chain;

[0015] The rotating shaft is rotatably mounted on the front and rear sides of the frame, and a sprocket is fixedly sleeved on the rotating shaft; the rotating shaft is connected to a drive motor.

[0016] The load-bearing beam is fixedly mounted on the frame in the front-to-back direction; the annular chain drive is mounted on the sprocket.

[0017] The upper half of the ring chain moves and is supported on the load-bearing beam.

[0018] Furthermore, a sliding track extending in the front-rear direction is fixed on the upper surface of the bearing beam, and a guide groove with an upper opening is provided on the upper surface of the sliding track.

[0019] The annular chain is slidably disposed in the guide groove.

[0020] Furthermore, the sprocket, the ring chain, the load-bearing beam, and the sliding track are all arranged in multiple sets at intervals along the left and right directions.

[0021] Furthermore, side guide rails are provided on both the left and right sides of the frame along the front-back direction, and several support plates are fixed at intervals along the length of the annular chain, with the two sides of the support plates slidably mounted on the side guide rails.

[0022] Furthermore, the electric rotating base includes a fixed base, a rotating tray, a central shaft, and a stepper motor;

[0023] The rotating tray is rotatably mounted above the fixed base and is fixedly connected to the central shaft;

[0024] The central shaft is rotatably mounted in the middle of the fixed base, and the central shaft is connected to the stepper motor via a drive.

[0025] The frame of the reversing conveyor section is fixed on a rotating pallet.

[0026] Furthermore, a gap is maintained between the rotating tray and the fixed base, and multiple upward-facing rotating wheels are fixed on the fixed base at circumferential intervals around the central axis; the wheel surfaces of the rotating wheels rotatably abut against the bottom of the rotating tray.

This allows control of the rotation and docking action of the reversing conveyor section, enabling precise connection and automatic switching of the zinc sheet stacks between different conveying paths. This improves the automation level of the system operation and the coordination of the work rhythm, effectively reduces manual intervention, and improves the overall reliability of the system operation.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0041] Example 1: This example aims to provide a continuous turnover and transportation device for zinc sheets, which is mainly used for continuous transportation of zinc sheets across workshops, addressing the problem that existing arc-shaped reversing conveyor lines are difficult to arrange in narrow workshop transportation corridors.

[0042] A continuous turnover transport device for zinc sheets, such as Figure 1 and Figure 2 It includes a continuous conveyor line section 1, a conveyor line section 2, and a turnover conveyor line 3, all set at the same height. The conveyor line section 1 and the conveyor line section 2 are arranged vertically. The turnover conveyor line 3 is located between the end point of the conveyor line section 1 and the starting point of the conveyor line section 2. The turnover conveyor line 3 includes a reversing conveyor section and an electric rotating base 5. The reversing conveyor section is set on the electric rotating base 5 and can be rotated by the electric rotating base 5 to be coaxial with the conveyor line section 1 or the conveyor line section 2, so that the reversing conveyor section can be turned and docked with the conveyor line section 1 and the conveyor line section 2 on the same horizontal plane by turning.

[0043] The end point of section 1 of the conveyor line, the starting point of section 2 of the conveyor line, and the middle section of the reversing conveyor section are respectively equipped with a first passing detection unit 101, a second passing detection unit 201, and a third passing detection unit 301 to obtain the position information of the passing zinc sheet stacks; the first passing detection unit 101, the second passing detection unit 201, the third passing detection unit 301 and the electric rotating base 5 are all connected to the controller.

[0044] When the first pass detection unit 101 is triggered, the controller determines that a zinc sheet is about to leave the first section 1 of the conveyor line and enter the reversing conveyor section. At this time, the controller controls the electric rotating base 5 to rotate, so that the reversing conveyor section is connected to the first section 1 of the conveyor line. When the second pass detection unit 201 is triggered, the controller determines that the zinc sheet has left the first section 1 of the conveyor line and has fully entered the reversing conveyor section. At this time, the controller controls the electric rotating base 5 to rotate, so that the reversing conveyor section is connected to the second section 2 of the conveyor line. When the third pass detection unit 301 is triggered, the controller determines that the zinc sheet has successfully and fully entered the second section 2 of the conveyor line and completed the reversing turn. At this time, the controller can control the electric rotating base 5 to return the reversing conveyor section to the state of being connected to the first section 1 of the conveyor line, in preparation for the next turn.

[0045] Conveyor line section 1, conveyor line section 2, and reversing conveyor section all include chain conveyor mechanism 4; such as Figure 3 The chain conveyor mechanism 4 includes a frame 401, a load-bearing beam 402, a rotating shaft 403, a sprocket 404, and a ring chain 405. For ease of demonstration, Figure 3 The circular chain 405 is simplified in the text.

[0046] The rotating shaft 403 is rotatably mounted on the front and rear sides of the frame 401, and the sprocket 404 is fixedly mounted on the rotating shaft 403; the rotating shaft 403 is connected to the drive motor 406; the bearing beam 402 is fixedly mounted on the frame 401 in the front-rear direction; the annular chain 405 is driven on the sprocket 404; the upper half of the annular chain 405 moves and rests on the bearing beam 402 to support the upper half of the annular chain 405.

[0047] In this embodiment, the zinc sheet is directly supported on the ring chain 405, and the bearing beam 402 provides rigid support in the longitudinal direction. The ring chain 405 needs to withstand the direct pressure of the zinc sheet and slide on the bearing beam 402. Therefore, in this embodiment, the ring chain 405 should preferably be thickened and have a larger size.

[0048] In addition, in this embodiment, the sprocket 404, the ring chain 405, the load-bearing beam 402 and the sliding track 407 are all arranged in three sets at intervals along the left and right directions to reduce the load-bearing capacity on each chain.

[0049] To further reduce friction during slippage, it is evident that... Figure 8 The upper surface of the supporting beam 402 is fixed with a sliding track 407 extending in the front-back direction. The upper surface of the sliding track 407 is provided with a guide groove 408 with an upper opening. The ring chain 405 is slidably disposed in the guide groove 408. On the one hand, the guide groove 408 can limit the ring chain 405 to prevent it from shifting to the left or right. On the other hand, the sliding track 407 can be polished, oiled, etc. to reduce the friction between the ring chain 405 and the sliding track 407.

[0050] like Figure 4-6 The electric rotating base 5 includes a fixed base 501, a rotating tray 502, a central shaft 503, and a stepper motor 504; the rotating tray 502 is rotatably disposed above the fixed base 501 and is fixedly connected to the central shaft 503; the central shaft 503 is rotatably disposed in the middle of the fixed base 501, and the central shaft 503 is drivenly connected to the stepper motor 504, which is controlled by a controller; the frame 401 of the reversing conveyor section is fixed on the rotating tray 502.

[0051] Furthermore, a gap is maintained between the rotating tray 502 and the fixed base 501. Four upward-facing rotating wheels 505 are fixed on the fixed base 501 with the central axis 503 as the center and at circumferential intervals. The wheel surfaces of the rotating wheels 505 rotate and abut against the bottom of the rotating tray 502 to support the edge of the rotating tray 502.

[0052] In this embodiment, the first pass detection unit 101, the second pass detection unit, and the third pass detection unit 301 all include a laser emitter 6 and a laser target 7. The laser emitter 6 and the laser target 7 are arranged opposite each other on both sides of the frame 401 and above the annular chain 405. Whenever the zinc plate passes by, it will block the laser emitted by the laser emitter 6, so that the laser signal received by the laser target 7 is interrupted, and the controller obtains the position information of the zinc plate at this time. When the laser signal received by the laser target 7 is restored, it means that the zinc plate has completely left the area of ​​the laser target 7, and the controller obtains the position information of the zinc plate again.

[0053] Example 2 is basically the same as Example 1, except that, as follows: Figure 7 and Figure 8 Side guide rails 409 are provided on both the left and right sides of the frame 401 along the front-back direction. Several support plates 4010 are fixed at intervals along the length of the ring chain 405. The support plates 4010 are slidably mounted on the side guide rails 409 on both sides. Therefore, the support plates 4010 directly bear the pressure of the zinc sheet and transmit the force to the side guide rails 409 to reduce the direct pressure on the ring chain 405.
