Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy extrusion molding, in particular to a large-diameter ingot turning and transferring device. Background Art

[0002] On the extrusion production line, the conveying direction of the ingot often needs to be changed depending on the process layout. Sometimes the ingot needs to be conveyed along the diameter direction of the ingot, and sometimes the ingot needs to be conveyed along the length direction of the ingot.

[0003] Currently, the industry's method of transferring ingots from conveying along their diameter to conveying along their length is mostly through ramp transfer, where the ingot's own gravity is used to roll it along the ramp onto the conveyor that transports it along its length. This method causes significant impact and damage to the conveyor that receives the ingot, especially since large-diameter ingots are too heavy and difficult to control. Another method in the industry is to extend the conveyor that transports the ingot along its diameter directly into the conveyor that transports the ingot along its length, and transfer the ingot by coordinating the lifting and lowering of the conveyor. This method has a high failure rate due to factors such as a very complex structure, certain curvature of the ingot, and asynchronous transfer.

[0004] Solving the above problems has become a top priority. Utility Model Content

[0005] In view of this, the utility model provides a large-diameter ingot turning and transferring device.

[0006] The technical solution is as follows:

[0007] The first aspect of the present application relates to a large-diameter ingot flipping and transferring device, comprising a first horizontal conveying mechanism and a second horizontal conveying mechanism, both of which have horizontal conveying directions, the conveying direction of the first horizontal conveying mechanism being perpendicular to the conveying direction of the second horizontal conveying mechanism, and the second horizontal conveying mechanism being arranged at the unloading end of the first horizontal conveying mechanism, and also comprising an ingot flipping and transferring mechanism, the ingot flipping and transferring mechanism comprising a flipping arm bracket arranged between the first horizontal conveying mechanism and the second horizontal conveying mechanism, at least one flipping arm installed on the flipping arm bracket for synchronous rotation, and a flipping arm driving assembly for driving each flipping arm to rotate, the rotation axis of each flipping arm being parallel to the conveying direction of the second horizontal conveying mechanism, and the outer edge of each flipping arm being provided with a positioning port adapted for the ingot; when the flipping arm driving assembly rotates the flipping arm to the flipping position, the ingot in each positioning port is transferred to the second horizontal conveying mechanism; when the flipping arm driving assembly rotates each flipping arm in the opposite direction to the initial position, the first horizontal conveying mechanism can convey an ingot to each positioning port.

[0008] By adopting the above-mentioned large-diameter ingot flipping and transferring device, between the first horizontal conveying mechanism that conveys the ingots along the diameter direction and the second horizontal conveying mechanism that conveys the ingots along the length direction, the flip arm driving assembly drives each flip arm to flip back and forth synchronously, so that the ingots on the first horizontal conveying mechanism can be smoothly transferred one by one to the second horizontal conveying mechanism. Not only is the impact and damage to the second horizontal conveying mechanism very small, but the ingot flipping and transferring mechanism is simple and reliable, and there is no synchronous coordination in the transfer process, which greatly reduces the failure rate. At the same time, it also plays a good protective role for the ingots, so that the surface of the ingots is not damaged; at the same time, when the ingots on the second horizontal conveying mechanism need to be returned to the first horizontal conveying mechanism, the flip arm driving assembly can also be used to drive each flip arm to flip back and forth synchronously and reverse the first horizontal conveying mechanism, which has excellent flexibility and versatility; and the entire device is fully automatic, which reduces labor costs and reduces the risk of safety accidents.

[0009] In some embodiments, when each flip arm rotates to the flip position, each positioning port is located at one end of the corresponding flip arm close to the second horizontal conveying mechanism, and the upper edge of each flip arm is an ingot support edge with an arc-shaped structure.

[0010] In some embodiments, the first horizontal conveying mechanism is two parallel horizontal conveying lines, and each flip arm is located between the two horizontal conveying lines.

[0011] In some embodiments, the horizontal conveyor lines each include two parallel conveyor chains and a chain drive assembly for driving the two conveyor chains to rotate synchronously.

[0012] In some embodiments, the second horizontal conveying mechanism includes a plurality of conveying guide rollers arranged side by side along the conveying path and a guide roller driving assembly capable of causing all the conveying guide rollers to rotate synchronously. When each flip arm rotates to the flip position, each flip arm is located between the corresponding two conveying guide rollers of the conveying roller.

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0024] like Figure 1-Figure 5As shown, a large-diameter ingot turning and transferring device mainly includes an ingot turning and transferring mechanism 2 and a first horizontal conveying mechanism and a second horizontal conveying mechanism 1, both of which have horizontal conveying directions. In addition, the conveying direction of the first horizontal conveying mechanism is perpendicular to the conveying direction of the second horizontal conveying mechanism 1, and the second horizontal conveying mechanism 1 is arranged at the unloading end of the first horizontal conveying mechanism, that is, the first horizontal conveying mechanism conveys the ingot A along the diameter direction of the ingot A, and the second horizontal conveying mechanism 1 conveys the ingot A along the length direction of the ingot A.

[0025] See Figure 1 and Figure 5 The first horizontal conveying mechanism includes two horizontal conveying lines 3 arranged in the horizontal direction. The two horizontal conveying lines 3 are parallel to each other, and the two horizontal conveying lines 3 can operate synchronously or independently, so that the ingot A can be transported stably and reliably in the diameter direction, and the posture of the ingot A on the first horizontal conveying mechanism can be adjusted.

[0026] Specifically, each horizontal conveyor line 3 comprises two parallel conveyor chains 31 and a chain drive assembly 32 for synchronously rotating the two conveyor chains 31. For each horizontal conveyor line 3, the two conveyor chains 31 are arranged horizontally and operate synchronously. Therefore, each ingot A is placed on four conveyor chains 31, further improving the stability of the ingot A's diametrical transport, making it particularly suitable for large-diameter ingots A.

[0027] The chain drive assembly 32 includes a first drive motor and a first transmission assembly. Each first drive motor drives the corresponding two conveyor chains 31 to run synchronously through the corresponding first transmission assembly, which is simple and reliable.

[0028] See Figure 1 and Figure 2 The second horizontal conveying mechanism 1 includes a plurality of conveying guide rollers 11 arranged side by side for convenience of conveying and a guide roller driving assembly 12 capable of causing all the conveying guide rollers 11 to rotate synchronously. The guide roller driving assembly 12 drives the synchronous rotation of each conveying guide roller 11, so that the ingot A can be conveyed stably and reliably along the length direction.

[0029] The guide roller driving assembly 12 includes a second driving motor and a second transmission assembly. The second driving motor drives the corresponding conveying guide rollers 11 to rotate synchronously through the second transmission assembly, which is simple and reliable.

[0030] See Figure 1-Figure 5The ingot turning and transferring mechanism 2 includes a turning arm support 21 disposed between the first horizontal conveying mechanism and the second horizontal conveying mechanism 1, at least one turning arm 22 mounted on the turning arm support 21 for synchronous rotation, and a turning arm drive assembly for driving each turning arm 22 to rotate. The rotation axis of each turning arm 22 is parallel to the conveying direction of the second horizontal conveying mechanism 1, and the outer edge of each turning arm 22 is provided with a positioning opening 221 adapted for the ingot A. Therefore, by controlling the back and forth turning of each turning arm 22 through the turning arm drive assembly, the ingots A on the first horizontal conveying mechanism can be transferred one by one to the second horizontal conveying mechanism 1.

[0031] Specifically, when each turning arm 22 is in its initial position, the first horizontal conveyor mechanism delivers an ingot A to each positioning port 221. The turning arm drive assembly is activated, rotating the turning arm 22 to the turning position. The ingot A in each positioning port 221 is then transferred to the second horizontal conveyor mechanism 1. The guide rollers on the second horizontal conveyor mechanism 1 rotate, driving the ingot A along its length. When the ingot A moves beyond the position of each turning arm 22, the turning arm drive assembly reverses the rotation of each turning arm 22 to its initial position. The first horizontal conveyor mechanism then delivers another ingot A to each positioning port 221. This reciprocating process continues.

[0032] Therefore, by driving the flip arms 22 to flip back and forth synchronously through the flip arm driving assembly, the ingots A on the first horizontal conveying mechanism can be smoothly transferred one by one to the second horizontal conveying mechanism 1. Not only is the impact and damage to the second horizontal conveying mechanism 1 very small, but the ingot flipping and transferring mechanism is simple and reliable, and there is no synchronous coordination in the transfer process, which greatly reduces the failure rate.

[0033] Among them, each turning arm 22 is located between the two horizontal conveying lines 3, and can provide reliable support for the ingot A when transferring the ingot A, thereby providing good protection for the ingot A and preventing the surface of the ingot A from being damaged.

[0034] Moreover, when each turning arm 22 rotates to the turning position, each turning arm 22 is respectively located between the corresponding two conveying guide rollers 11 of the conveying roller, so that the ingot A is directly placed from top to bottom on the conveying guide rollers 11 of the second horizontal conveying mechanism 1 when each turning arm 22 is about to rotate to the turning position, and then after the second horizontal conveying mechanism 1 conveys the ingot A away, each turning arm 22 rotates again. The coordination process is not only very simple, but also extremely reliable, which can effectively reduce the failure rate.

[0035] Specifically, when each flip arm 22 rotates to the flip position, each positioning port 221 is located at one end of the corresponding flip arm 22 close to the second horizontal conveying mechanism 1, and the upper edge of each flip arm 22 is an ingot support edge 222 with an arc-shaped structure. Each ingot support edge 222 extends from the corresponding positioning port 221 to the end of the flip arm 22 away from the second horizontal conveying mechanism 1. The central axis of each ingot support edge 222 coincides with the rotation axis of the corresponding flip arm 22, and an ingot A on the first horizontal conveying mechanism and closest to its unloading end is supported on each ingot support edge 222 at the same time.

[0036] Since each ingot supporting edge 222 is an arc-shaped structure coaxially arranged with the rotation axis of the corresponding flipping arm 22, when the flipping arm 22 rotates back and forth, the ingot supporting edge 222 will not cause the ingot A released from it to move forward and backward, thereby stabilizing the position of the ingot A on the first horizontal conveying mechanism. This not only improves the reliability and stability of feeding, and makes it less likely for the ingot A on the first horizontal conveying mechanism to roll back and forth during the waiting process, but also effectively separates the flipped ingot A from the ingot A to be flipped, ensuring that only one ingot A can be flipped at a time.

[0037] The first horizontal conveying mechanism and the ingot turning and transferring mechanism 2 are both installed on the device base B, wherein the turning arm bracket 21 includes two vertically opposite bracket columns 211 and a turning arm shaft 212 that can be rotatably installed on the two bracket columns 211 along the horizontal direction. The lower ends of the two bracket columns 211 are fixedly installed on the device base B, and the two ends of the turning arm shaft 212 are respectively rotatably installed on the upper ends of the corresponding bracket columns 211 through bearings, which is simple and reliable.

[0038] Each of the tilting arm shafts 212 is synchronously mounted on the tilting arm shaft 212, i.e., the tilting arm shaft 212 rotates synchronously with each of the tilting arm shafts 212. The tilting arm drive assembly includes at least one tilting drive cylinder 23. The end of the cylinder body of each tilting drive cylinder 23 is hinged to the device base B, and the end of the piston rod of each tilting drive cylinder 23 is hinged to the corresponding tilting arm 22. Therefore, by reciprocating the piston rods of each tilting drive cylinder 23, each of the tilting arms 22 can be driven to rotate back and forth synchronously. This is not only simple and reliable, but also has a large output torque of the tilting drive cylinder 23, making it particularly suitable for large-diameter ingots A.

[0039] See Figure 1 and Figure 5An initial position proximity switch 5 and a flip position proximity switch 6 are provided on the top of one of the support columns 211, wherein the initial position proximity switch 5 is located on the side of the flip arm shaft 212 close to the first horizontal conveying mechanism, and the flip position proximity switch 6 is located on the side of the flip arm shaft 212 close to the second horizontal conveying mechanism 1, and an initial position sensing block 7 adapted to the initial position proximity switch 5 and a flip position sensing block 8 adapted to the flip position proximity switch 6 are provided on the flip arm 22.

[0040] Therefore, when the initial position proximity switch 5 senses the initial position sensing block 7, each turning arm 22 stops rotating and stops precisely at the initial position. When the turning position proximity switch 6 senses the turning position sensing block 8, each turning arm 22 stops rotating and stops precisely at the turning position. This ensures the movement accuracy of each turning arm 22, thereby improving the stability and reliability of the turning and transporting of the ingot A.

[0041] See Figure 1 、 Figure 4 and Figure 5 End limit guide frames 4 are provided on both sides of the first horizontal conveying mechanism. The extension directions of the two end limit guide frames 4 are parallel to the conveying direction of the first horizontal conveying mechanism. Both ends of each ingot A located on the first horizontal conveying mechanism are located between the two end limit guide frames 4, thereby effectively limiting the position of each ingot A located on the first horizontal conveying mechanism and preventing the ingot A from falling from the first horizontal conveying mechanism.

[0042] Specifically, the end limit guide frame 4 includes a limit beam arranged parallel to the conveyor chain 31 and two beam mounting posts. The limit beam is mounted on the two beam mounting posts, which is simple and reliable. At the same time, the limit beam is slightly higher than the top surface of the conveyor chain 31, thereby effectively limiting the position of the ingot A.

[0043] See Figure 1-Figure 3 as well as Figure 5 At least one side limit frame 10 is provided on the side of the second horizontal conveying mechanism 1 away from the ingot turning and transferring mechanism 2. In this embodiment, a plurality of side limit frames 10 are preferably used. The side limit frames 10 are distributed along the conveying direction of the second horizontal conveying mechanism 1. When the ingot A is transferred to the second horizontal conveying mechanism 1, the ingot A is supported on the side limit frames 10 or is close to the side limit frames 10, thereby effectively preventing the ingot A from sliding off the outside of the second horizontal conveying mechanism 1, thereby improving the safety of the transfer of the ingot A.

[0044] Specifically, the side limit frame 10 includes a vertically arranged limit frame bracket, the top of which extends horizontally toward the second horizontal conveying mechanism 1, and a limit support plate is installed at its outer end, thereby being able to play a good limiting role on the ingot A.

[0045] Further, see Figure 1-Figure 3 This embodiment also includes a safety protection light curtain 9, which is located at one end of the first horizontal conveying mechanism away from the second horizontal conveying mechanism 1. When the safety protection light curtain 9 detects that someone enters, the entire device will immediately shut down to protect the safety of the operator.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
