Description

Technical Field

[0001] The invention relates to the technical field of copper rod production, in particular to an automatic copper plate feeding line. Background Art

[0002] In existing technology, copper rods are typically produced using a continuous casting and rolling process. This production line uses plate-shaped electrolytic copper (hereinafter referred to as copper plate) as raw material. The copper plate is melted in a vertical furnace at high temperature, and then continuously cast and rolled to produce copper rods. Currently, the more mature production methods include the SCR process (developed by Southern Wire in the United States) and the Contirod process (also known as the Contirod process) developed by SMS Germany.

[0003] Taking the SCR-3000 copper rod production line on the southern route of the United States as an example, although the production line has achieved automation in the preparation of copper rods, the input of raw materials mainly relies on forklifts to transport copper plates for addition. Specifically, after the copper plates arrive, they are unloaded by forklifts and stacked in designated locations. When copper plates need to be added to the furnace, the forklift then inserts the stacked copper plates and places them on the hopper of the vertical furnace. The hopper then lifts the copper plates and dumps them into the furnace.

[0004] Specifically, the prior art has the following defects:

[0005] First, in the existing technology, when transporting copper plates, there is too much reliance on forklifts. Due to the repeated operations of copper plate arrival, unloading and stacking, loading and other links, the forklifts are frequently used, which increases the forklift load, resulting in high forklift operating costs and high maintenance costs. In addition, this link is a cyclic and monotonous operation, and the labor intensity of the operators is relatively high.

[0006] Secondly, in the prior art, the copper plates are placed into the hopper by a forklift, such as Figure 18 As shown, the forklift first forks the stacked copper plates 9 to the top of the hopper 90 and to one side of the hopper 90, adjusts the position so that the center of gravity of the copper plates 9 is located inside the hopper 90, and then controls the fork 91 to descend. When the copper plates 9 come into contact with the top of the hopper 90, the copper plates 9 flip over and fall into the hopper 90 under the action of gravity, thereby placing the copper plates 9 into the hopper 90. The above process has high technical requirements for the forklift operator. If the position is misjudged and the center of gravity of the copper plates 9 is located outside the hopper 90, the copper plates 9 will fall to the ground, damaging the workshop floor and even causing a safety accident. Moreover, even skilled operators need to spend more time aligning the position, which is not conducive to improving work speed and efficiency. Summary of the Invention

[0007] The purpose of the present invention is to address the above-mentioned defects in the prior art and provide an automatic copper plate loading line, which can automatically transport copper plates into the hopper of a melting furnace, thereby improving the degree of automation of copper plate production.

[0008] To achieve the above-mentioned object of the invention, the present invention proposes an automatic copper plate feeding line, which comprises:

[0047] The technical solution of the present invention is further described in detail below in conjunction with preferred embodiments and the accompanying drawings.

[0048] like Figure 1 As shown, a copper plate automatic loading line corresponding to a preferred embodiment of the present invention includes a copper plate conveyor line 1, a feeding vehicle 2, a feeding forklift 3 and a copper plate feeder 4.

[0049] like Figure 2 As shown, the copper plate conveyor line 1 includes a fixed first frame 10, a first conveying mechanism 11 connected to the first frame 10, and a tray 12 placed on the first conveying mechanism 11. The first conveying mechanism 11 can adopt a chain transmission mechanism or a roller transmission mechanism.

[0050] In this embodiment, Figure 3 As shown, the first conveying mechanism 11 adopts a chain transmission mechanism, which includes a first conveying frame 110. The first conveying frame 110 is welded with square tubes, and includes a first frame layer 110a and a second frame layer 110b spaced apart from each other. The first chain support plate 110c is welded to the first frame layer 110a and the second frame layer 110b.

[0051] A first driving shaft 111 and two first driven shafts 112 are rotatably connected to the first conveyor frame 110. The first driving shaft 111 and the first driven shaft 112 are arranged in parallel and connected to first seated bearings 117 on the first conveyor frame 110, thereby being able to rotate about their respective axes. A first driving sprocket 113 is connected to each end of the first driving shaft 111, and a first driven sprocket 114 is connected to the first driven shaft 112. The first driving sprocket 113 and the first driven sprocket 114 are connected by a first chain 115.

[0052] The first conveying mechanism 11 further includes a first reduction motor 116 for driving the first driving shaft 111 to rotate. The first reduction motor 116 and the first driving shaft 111 can be directly connected or connected via a first chain transmission assembly 118. The first reduction motor 116 is fixed to the first conveying frame 110. By driving the first driving shaft 111 to rotate, the first chain 115 is driven to rotate, thereby driving the tray 12 on the first chain 115 to move, thereby conveying the copper plate 5.

[0053] refer to Figure 3 and Figure 4 The first chain 115 is arranged in the first chain support plate 110c, and the first chain support plate 110c is provided with a first rib 110f located on both sides of the first chain 115, which can play a guiding role during the movement of the chain and prevent the chain from separating from the sprocket.

[0054] like Figure 5 As shown, the copper plate automatic feeding line of the present invention can include multiple sections of first conveying mechanisms 11, which are arranged on the same straight line. The guide grooves (110e) of each first conveying mechanism 11 are interconnected, so that the tray (12) can be moved between each first conveying mechanism (11). In other words, the conveying length of the copper plate conveying line 1 can be adjusted by increasing or decreasing the number of first conveying mechanisms 11, thereby better adapting to the conveying length requirements of different workshops.

[0055] The structure of the tray 12 is as follows Figure 6 As shown, the upper surface 120 is provided with a plurality of slots 121 spaced apart from each other. The slots 121 are used for forking the forks of a forklift to pass through, thereby placing the copper plates on the forks onto the pallet 12. It is understood that a pallet 12 with a similar structure is also provided on the ground. When the copper plates 5 are transported to the unloading site, the copper plates 5 are stacked on the pallet 12 on the ground, so that when the copper plates 5 are subsequently inserted and removed, only the copper plates 5 can be moved without moving the pallet 12.

[0056] Downward-extending limit plates 122 are also provided on both sides of the tray 12. The limit plates 122 extend to the outside of the first chain support plate 110c, preventing the tray 12 from detaching from the first conveying mechanism 11, thereby ensuring safety during the conveying process. In addition, a protruding guide rod 123 is provided below the tray 12. Two parallel connecting posts 110d are welded to the first shelf 110a, forming a guide groove 110e between the two connecting posts 110d. The guide rod 123 is fitted into the guide groove 110e. The end of the guide groove 110e is a bell-shaped end, which can facilitate the entry of the guide rod 123, thereby limiting the movement and deviation of the tray 116 in a direction perpendicular to the conveying direction, allowing the tray 12 to move accurately along the conveying direction, more safely and reliably.

[0057] Preferably, one end of the copper plate conveyor line 1 extends outdoors, so that a forklift can fork the copper plate 5 onto the tray 12 of the first conveying mechanism 11 outdoors, and the copper plate conveyor line 1 transports the tray 12 indoors. This allows the forklift to operate without entering the workshop, effectively eliminating safety hazards. In the case of a small space in the workshop, such as Figure 1 As shown, the entire copper plate conveyor line 1 can also be set up outdoors, and only the feeding forklift 3 can transport the copper plates 5 into the workshop. Figure 1 The middle wall 8 is the outer wall of the workshop, and the melting furnace 7 and the copper plate conveying line 1 are located inside and outside the workshop respectively.

[0058] The feeding trolley 2 is used to transport the copper plates 5 on the copper plate conveyor line 1 to the feeding forklift 3. In this embodiment, it includes a first AGV trolley 21 and a second conveying mechanism 20 connected to the first AGV trolley. The second conveying mechanism 20 is similar in structure to the above-mentioned first conveying mechanism 11, and also conveys the pallet 12 and the copper plate 5 through a chain transmission mechanism, which will not be repeated here.

[0059] An AGV is a transport vehicle equipped with an electromagnetic or optical automatic guidance device that can travel along a specified guide path. Based on the different navigation methods used, it can be divided into electromagnetic induction guided AGVs, laser guided AGVs, and vision guided AGVs. Laser guided AGVs are preferred because they use laser positioning technology and can travel along a set track without the need for other positioning equipment or magnetic strips on the ground. Their travel paths are flexible and can be changed simply by computer.

[0060] like Figure 8 As shown, a baffle 22 and a limit switch 23 are connected to the second conveying mechanism 20 of the feeding trolley 2 to locate the position of the pallet 12 on the feeding trolley 2 and ensure the consistency of the position of the pallet 12; when the second conveying mechanism 20 conveys the pallet 12 until it touches the limit switch 23, the reduction motor of the second conveying mechanism 20 stops, and the baffle 22 locates the position of the pallet 12.

[0061] In addition to the above structure, the feeding vehicle 2 can also directly adopt the laser navigation roller AGV vehicle in the prior art.

[0062] The upper surfaces of the second conveying mechanism 20 and the first conveying mechanism 11 are basically flush, so that the pallet 12 and copper plate 5 on the first conveying mechanism 11 can be smoothly conveyed to the second conveying mechanism 20, and then the feeding vehicle 2 can be moved to the conveying route 6 of the feeding forklift 3.

[0063] like Figure 9As shown, the feeding forklift 3 is used to insert the copper plates 5 on the feeding trolley 2 and transport the copper plates 5 to the copper plate feeder 4. The feeding forklift 3 adopts the forklift-type AGV trolley in the prior art, which includes a second AGV trolley 30 and an insertion and extraction component 31 connected to the second AGV trolley 30. The insertion and extraction component 31 is similar to the insertion and extraction component at the front end of the forklift, including a vertical frame 310 fixedly mounted on the second AGV trolley 30, a connecting frame 311 slidably coupled to the vertical frame 310, two forks 312 spaced apart on the connecting frame 311, and a driving device 313 for driving the connecting frame 311 to move in the vertical direction. The connecting frame 311 and the vertical frame 310 can be connected by a vertically arranged guide rail, so that the connecting frame 311 can move vertically along the guide rail, driving the forks 312 to move up and down. The spacing between the two forks 312 is preferably adjustable so that it can be suitable for different types of pallets 12. The driving device 313 can be an oil cylinder, which lifts the connecting frame 311 to move, or it can be other driving methods, such as a motor plus chain drive driving method.

[0064] Preferably, the feeding forklift 3 also adopts a laser guidance method, that is, a laser navigation forklift-type AGV trolley is adopted.

[0065] like Figure 10 As shown, the feed route 1a of the copper plate conveyor line 1 and the conveyor route 6 of the feeder forklift 3 are arranged in a T-shape. The starting position 2a of the feeder trolley 2 is located at the end of the copper plate conveyor line 1, where it receives the pallets 12 and copper plates 5 delivered by the copper plate conveyor line 1. The end position 2b of the feeder trolley 2 is at the intersection of the feed route 1a and the conveyor route 6. After receiving the pallets 12 and copper plates 5 from the copper plate conveyor line 1, the feeder trolley 2 moves to the intersection (end position 2b), where it transfers the copper plates 5 to the feeder forklift 3. The movement route of the feeder trolley 2 is pre-set and it automatically stops at the designated position. When the feeding cart 2 moves to the end position 2b, the fork 312 of the feeding forklift 3 is aligned with the slot 121 of the pallet 12, and the feeding forklift 3 moves a set distance toward the feeding cart 2 so that the fork 312 is inserted into the slot 121. After moving into position, the fork 312 rises and lifts the copper plate 5 until the fork 312 is out of the slot 121. Then the feeding cart 2 returns to the starting position 2a and prepares for the next feeding. After the feeding cart 2 leaves, the feeding forklift 3 can move along the conveying route 6 to the copper plate feeder 4 and place the copper plate 5 it has inserted onto the copper plate feeder 4.

[0066] like Figure 11 As shown, the copper plate feeder 4 includes a fixed frame 40 , a third conveying mechanism 41 , and a lifting device 42 connected between the fixed frame 40 and the third conveying mechanism 41 .

[0067] The fixed frame 40 is preferably a square tube welded structure, and a plurality of support frames for supporting the copper plate 5 are provided on its upper end. Figure 12 As shown, there are three support frames, namely: a first support frame 400a and a second support frame 400b arranged in front and back, and a third support frame 400c arranged between the first support frames 400a and 400b, and the third support frame 400c is located on the right side of the fixed frame 40. Figure 13 As shown, the width B of the first support frame 400a and the second support frame 400b is smaller than the distance L between the two forks 312 of the feeding forklift 3. When feeding, the two forks 312 are respectively located on both sides of the first support frame 400a, so that when the forks 312 are lowered, the copper plate 5 can be placed on the support frame.

[0068] A receiving groove 401 is formed between the first supporting frame 400a and the second supporting frame 400b. The receiving groove 401 is used to receive the third conveying mechanism 41. Figure 12 .

[0069] like Figure 14 As shown, the third conveying mechanism 41 has a similar structure to the first conveying mechanism 11, and includes: a second conveying frame 410, which is welded by square tubes, and includes an upper frame layer 410a and a lower frame layer 410b spaced apart from each other, and a second chain support plate 410c is welded on the upper frame layer 410a and the lower frame layer 410b.

[0070] A second driving shaft 411 and two second driven shafts 412 are rotatably connected to the second conveyor frame 410. The second driving shaft 411 and the second driven shaft 412 are arranged in parallel and are connected to second seated bearings 417 on the second conveyor frame 410 so as to be able to rotate about their respective axes. A second driving sprocket 413 is connected to each end of the second driving shaft 411, and a second driven sprocket 414 is connected to the second driven shaft 412. The second driving sprocket 413 and the second driven sprocket 414 are connected by a second chain 415.

[0071] The third conveying mechanism 41 further includes a second reduction motor 416 that drives the second driving shaft 411 to rotate. The second reduction motor 416 and the second driving shaft 411 can be directly connected or connected via a second chain transmission assembly 418. The second reduction motor 416 is fixed to the second conveying frame 410. By driving the second driving shaft 411 to rotate, the second chain 415 is driven to rotate, thereby driving the tray 12 on the second chain 415 to move, thereby conveying the copper plate 5.

[0072] like Figure 15As shown, the second chain 415 is arranged in the second chain supporting plate 410c, and the second chain supporting plate 410c is provided with second ribs 410d located on both sides of the second chain 415, which can play a guiding role during the movement of the chain and prevent the chain from separating from the sprocket.

[0073] refer to Figure 16 The lifting device 42 includes a lower seat bearing 420 connected to the fixed frame 40, an upper seat bearing 421 connected to the second conveyor frame 410, and a hydraulic cylinder 422 connected between the upper seat bearing 421 and the lower seat bearing 420. In this embodiment, there are four hydraulic cylinders, each of which has a cylinder body 422a connected to the lower seat bearing 420 via a lower rotating shaft 423, and a piston shaft 422b connected to the upper seat bearing 421 via an upper rotating shaft 424. When the hydraulic cylinder 422 is retracted, the third conveying mechanism 41 is accommodated in the receiving groove 401, allowing the feed forklift 3 to place the copper plate 5 onto the support frame. After the feed forklift 3 leaves, the hydraulic cylinder 422 pushes the third conveying mechanism 41 upward, causing the second chain 415 to contact and lift the copper plate 5. Then, the second reduction motor 416 drives the second chain 415 to rotate, conveying the copper plate 5 into the hopper 70.

[0074] like Figure 14 As shown, a limiting hole 410f is provided on the second conveying frame 410, and the third support frame 400c is passed through the limiting hole 410f. During the lifting and lowering process of the third conveying mechanism 41, the three support frames can play a guiding role to prevent or reduce the third conveying mechanism 41 from shaking in the horizontal direction.

[0075] like Figure 17 As shown, the hopper 70 of the melting furnace 7 is provided with a first inclined support surface 71 and a second inclined support surface 72, between which a V-shaped trough 73 is formed for accommodating the copper plates 5. The copper plate feeder 4 is arranged close to the hopper 70, and the hopper 70 is located below the conveying direction of the copper plate feeder 4, so that the copper plates 5 on the second chain 415 can be dumped into the trough 73 after being separated from the chain, completing the feeding of the hopper 70. The hopper 70 can be separated from the fixed frame 40 by a certain distance, and the two sides can also be arranged to be close to each other without affecting the movement of the hopper 70.

[0076] Hopper 70 is connected to the winch of the continuous casting and rolling production line and is driven by the winch. A detection camera is installed at the mouth of the melting furnace 7, which can monitor the melting conditions inside the furnace through video. The charging process can be controlled based on the real-time melting conditions. The loading system can also be remotely controlled by sending commands via a wireless signal transmission device.

[0077] The automatic copper plate feeding line of the present invention is provided with a control system, and the electrical components in the feeding line are all connected to the control system for communication, and can control the electrical components in the feeding line, such as controlling the forward and reverse rotation and start and stop of the motor, controlling the extension and retraction of the hydraulic cylinder, and controlling the movement of the AGV trolley, etc. At the same time, it also realizes linkage control with the continuous casting and rolling production system through the PLC system, so that it can feed materials in time according to the melting situation in the furnace 7. Pressure sensors or photoelectric sensors and other sensors can be set on the copper plate conveyor line 1, the feeding car 2, the feeding forklift 3 and the copper plate feeder 4 to sense whether there are copper plates 5 placed thereon, so as to facilitate the control system to make judgments and issue instructions. The electrical control part in the present invention, such as the layout of the circuit and the compilation of the program, can be achieved by relevant means in the prior art, which will not be repeated here.

[0078] The feeding steps of the copper plate automatic feeding line of the present invention are as follows:

[0079] Step 1: The staff operates a forklift to pick up the stacked copper plates 5 and place them on the tray 12 of the copper plate conveyor line 1;

[0080] Step 2: The first reduction motor 116 on the copper plate conveyor line 1 is started to drive the tray 12 and the copper plate 5 to move to the feeding vehicle 2;

[0081] Step 3: After receiving the pallet 12 and the copper plate 5, the feeding vehicle 2 moves to the conveying route 6 of the feeding forklift 3, specifically, moves to the end position 2b;

[0082] Step 4: The feeding forklift 3 moves and takes out the copper plate 5 from the feeding trolley 2. After that, the feeding trolley 2 returns to its original position and transports the tray 12 back to the copper plate conveying line 1.

[0083] Step 5: The feeding forklift 3 moves to transport the copper plate 5 to the support frame of the copper plate feeder 4, and then the feeding forklift 3 returns to its original position;

[0084] Step 6: The lifting device 42 of the copper plate feeder 4 drives the third conveying mechanism 41 to rise, so that the third conveying mechanism 41 holds up the copper plate 5;

[0085] Step 7: The third conveying mechanism 41 conveys the copper plates 5 horizontally and pours the copper plates 5 into the hopper 70 . Then the hopper 70 rises and pours the copper plates 5 into the melting furnace 6 .

[0086] The copper plate automatic feeding line of the present invention has at least the following advantages:

[0087] 1. The automatic copper plate loading line of the present invention is provided with a copper plate conveyor line, a feeding trolley, a copper plate feeder and a feeding forklift. When feeding, the staff only needs to place the copper plates on the tray of the copper plate conveyor line. The copper plate conveyor line can move the tray and the copper plates to the feeding trolley. The feeding trolley can move to the feeding route of the feeding forklift. The feeding forklift picks up the copper plates on the feeding trolley and then transports the copper plates to the copper plate feeder. The copper plate feeder transports the copper plates into the hopper, thereby greatly improving the automation of the copper plate loading process, reducing the use load of the forklift, and improving production efficiency.

[0088] 2. The copper plate conveyor line of the present invention is provided with a plurality of first conveying mechanisms arranged in a straight line. The first conveying mechanisms carry and convey pallets through a chain transmission mechanism, thereby realizing horizontal conveyance of copper plates and reducing the frequency and load of forklift use. At the same time, the copper plate conveyor line can adjust the conveying length by increasing or decreasing the number of first conveying mechanisms, and can effectively adapt to working environments of different lengths.

[0089] 3. In the present invention, at least one end of the copper plate conveyor line extends outdoors, so that a forklift can place the copper plates on the copper plate conveyor line outdoors without entering the workshop, which greatly improves work efficiency and reduces the safety risks caused by forklifts entering indoor operations;

[0090] 4. The copper plate feeder in the present invention is provided with a support frame for supporting the copper plate, a third conveying mechanism and a lifting device that can lift the third conveying mechanism. After the copper plate is placed on the support frame, the lifting device can lift the third conveying mechanism, so that the copper plate is transferred to the third conveying mechanism, and then the third conveying mechanism horizontally transports it to the hopper. There is no need for a forklift to insert the copper plate and then put it into the hopper, which reduces the requirements for operators, is more convenient and quick, and reduces safety risks.
