Description

Technical Field

[0001] The present invention belongs to the technical field of thermos cup processing equipment, and particularly relates to a multi-station necking machine with an automatic loading and unloading function. Background Art

[0002] During the processing of thermos cups, there is a process that requires necking of steel pipes. The steel pipes are placed on a rotating placement mold by a robotic arm, and then fixed by a pressing device. While the steel pipes are rotating, the necking wheels approach and align with the steel pipes for extrusion, thus completing the necking of the steel pipes. Currently, the multi-station necking machines on the market place the products to be processed on the stations provided with placement molds and then perform necking. The products are all placed on the corresponding stations by the robotic arms arranged near the necking machines. Each robotic arm can only place one product on the corresponding station at a time, and then the necking wheels on the corresponding stations process the products. Only after placing one product can a new product be grabbed for processing. After the product processing is completed, it is taken off by the robotic arm. The entire material taking and loading process is separately carried out. The products processed on each station cannot be loaded and unloaded synchronously, and the products on each station cannot be processed synchronously. This will result in waiting gaps in some stations and the processing can only be carried out after the products are transported to the stations, reducing the processing efficiency of the products. At the same time, there is only one robotic arm for loading and unloading the products, which cannot meet the simultaneous loading and unloading of multiple stations and has a low degree of automation. Since the robotic arm has a complex structure and occupies a large space, pairing a robotic arm for each station will greatly increase the manufacturing cost of the products. Therefore, it is necessary to design a multi-station necking machine with an automatic loading and unloading function to overcome the above difficulties. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention designs a multi-station necking machine with an automatic loading and unloading function. The present invention is provided with a loading device and an unloading device on the body platform, and through the cooperation of a rotating component and a linkage component, the products on each station are loaded or unloaded synchronously. After the product processing is completed, it is taken away by the unloading device. At the same time, the loading device immediately clamps a new product to the station for processing. The processing gaps between the products are short, the continuity is good, and the loading and unloading efficiency is high.

[0004] The object of the present invention is achieved by the following technical solutions: A multi-station necking machine with automatic loading and unloading functions, including a body platform, a moving plate, guide columns, and a placement mold; several guide columns fixedly connected to the body platform are provided on the body platform, a moving plate is sleeved and installed on the guide columns, and a lifting component for driving the moving plate to move relative to the guide columns is provided on the body platform; a feeding device and a discharging device are provided on the moving plate, and both the feeding device and the discharging device include a rotating component, a linkage component, a swinging component, and a clamping component; the rotating component is arranged on the moving plate and moves up and down synchronously with it, the rotating component includes a rotating motor and several rotating shafts arranged side by side and at equal intervals, each of the rotating shafts is linked with each other through a linkage component, and the rotating motor drives one of the rotating shafts to rotate; a swinging component is provided at the end of each rotating shaft, the swinging component includes a first motor, a rotating member, and a mounting seat, the mounting seat is fixedly connected to the rotating shaft, the first motor drives the rotating member to rotate relative to the mounting seat while working, and a clamping component fixedly connected to it is provided on the rotating member; the feeding device and the discharging device are distributed on the front and rear sides of the placement mold, and the rotating components on the feeding device and the discharging device rotate synchronously.

[0005] Preferably, the lifting component includes a pair of first cylinders and a pair of support bases, the support bases are fixedly connected to the body platform, the first cylinders are installed on the support bases, the piston shafts of the first cylinders are fixedly connected to the moving plate, and the first cylinders drive the moving plate to move up and down relative to the guide columns while working.

[0006] The first cylinders drive the moving plate to move up and down relative to the guide columns while working. The feeding device and the discharging device are both arranged on the moving plate, and both the feeding device and the discharging device include a rotating component; when the moving plate moves up, the feeding device clamps the product to be processed and moves up, and the discharging device clamps the processed product and moves up; then the rotating components on the feeding device and the discharging device work synchronously, the feeding device transfers the product to be processed to directly above the placement mold, and the discharging device transfers the processed product to directly above the discharging assembly line; then the moving plate moves down, the feeding device places the product to be processed on the placement mold, and the discharging device places the processed product on the discharging assembly line. Thus, it can be seen that the loading and unloading of the product are carried out synchronously, increasing the output of the product and improving the processing efficiency.

[0007] Preferably, the rotating component includes a rotating motor and several rotating shafts arranged side by side and at equal intervals, each of the rotating shafts is installed on the moving plate through a bearing; the rotating motor is fixedly installed on the upper end surface of the moving plate, and the rotating motor is connected to the rotating shaft arranged near the middle position of the moving plate and drives it to rotate.

[0008] When the rotary motor operates, it drives the rotating shaft to rotate. All the rotating shafts are connected by a linkage component. In this way, one rotary motor can drive all the rotating shafts to rotate, reducing the manufacturing cost. At the same time, the synchronization of the rotating shafts during rotation is better. A swing component is provided at the end of the rotating shaft, and a clamping component for clamping the product is provided on the swing component. When the rotating shaft rotates, the clamping component clamps the product and rotates synchronously.

[0009] Preferably, each of the rotating shafts is connected by a linkage component. The linkage component includes a linkage pull plate, a positioning pin shaft, and a number of connecting pieces corresponding one-to-one to the number of rotating shafts. One end of the connecting piece is fixedly connected to the rotating shaft, and the other end is hinged to the linkage pull plate through the positioning pin shaft. When the rotary motor drives one of the rotating shafts to rotate, the remaining rotating shafts rotate synchronously. While each rotating shaft rotates, it drives the connecting piece to rotate. The rotation range of each connecting piece is between - degrees. A number of mounting notches for mounting the connecting pieces are provided on the linkage pull plate. The number of the mounting notches corresponds one-to-one to the connecting pieces, and the mounting notches are arranged side by side and at equal intervals on the linkage pull plate. The end face of the linkage pull plate facing away from the rotating shaft is always parallel to the front end face of the fuselage platform.

[0010] Each rotating shaft is hinged to the linkage pull plate through a connecting piece. The rotary motor first drives one of the rotating shafts to rotate. The rotating shaft drives the connecting piece fixedly connected to it to rotate. While the connecting piece rotates, it generates a thrust on the linkage pull plate. In this way, the linkage pull plate moves relative to the rotary motor. While the linkage pull plate moves, it approaches or moves away from the rotary motor. While the linkage pull plate moves, it drives all the remaining connecting pieces to rotate. While the remaining connecting pieces rotate, they drive the rotating shafts fixedly connected to them to rotate. Therefore, only one rotary motor is needed to drive all the rotating shafts to rotate, and the synchronization of each rotating shaft during rotation is good. Then the products at each station can be loaded or unloaded synchronously.

[0011] Preferably, the rotating shafts on the loading device and the unloading device are all arranged side by side and at equal intervals. The distance between each rotating shaft on the loading device and the front end face of the fuselage platform is the same. The distance between each rotating shaft on the unloading device and the front end face of the fuselage platform is the same. A number of first through holes for mounting the positioning pin shafts are provided on each linkage pull plate. Each of the first through holes is arranged side by side and at equal intervals. The distance between each first through hole on the loading device and the front end face of the fuselage platform is the same. The distance between each first through hole on the unloading device and the front end face of the fuselage platform is the same. The number of the rotating shafts and the first through holes both corresponds one-to-one to the number of the placement molds.

[0012] The distance between each of the rotating shafts on the loading device and the front end face of the fuselage platform is the same, so that the rotating shafts on the loading device are all on the same axis. The distance between the first through holes on the loading device and the front end face of the fuselage platform is the same, so that the linkage pull plate is always parallel to the front end face of the fuselage platform every time it moves. Only in this way can the linkage pull plate drive each of the connecting pieces to rotate by the same angle, and then the rotation angles of each of the rotating shafts will be consistent, ensuring that the clamping assembly can be accurately above the mold placement position or above the feeding assembly line during the rotation of the rotating shaft. Similarly, the rotating shafts on the unloading device are all on the same axis, and the distance between the first through holes on the unloading device and the front end face of the fuselage platform is the same. Therefore, during the rotation of the rotating shafts on the unloading device, the clamping assembly can be accurately above the mold placement position or above the discharging assembly line.

[0013] Preferably, the mold placements are arranged side by side and at equal intervals on the fuselage platform, and the distance between each mold placement and the front end face of the fuselage platform is the same; there is one of the rotating shafts between any two of the mold placements; a loading device is provided in front of the mold placements, and an unloading device is provided behind the mold placements; the distance from the rotating shaft on the loading device to the front end face of the fuselage platform is closer than the distance from the mold placement to the front end face of the fuselage platform. While the rotating motor drives the rotating shaft to rotate, the connecting piece drives the linkage pull plate to approach or move away from the mold placement; the distance from the rotating shaft on the unloading device to the front end face of the fuselage platform is farther than the distance from the mold placement to the front end face of the fuselage platform. While the rotating motor drives the rotating shaft to rotate, the connecting piece drives the linkage pull plate to approach or move away from the mold placement.

[0014] The distance between each of the mold placements and the front end face of the fuselage platform is the same, so that each of the mold placements is on the same axis. The rotating shafts on the loading device are all on the same axis and are located in front of the mold placements, and the rotating shafts on the unloading device are all on the same axis and are located behind the mold placements. Then, when the loading device and the unloading device work synchronously, they will not interfere with each other, and the clamping assembly of the loading device will not touch the clamping device on the unloading device, ensuring that the loading device and the unloading device can operate synchronously and without interference.

[0015] Preferably, each of the rotating shafts is provided on the same side as its adjacent mold placement and they are in one-to-one correspondence. The distance between each of the rotating shafts on the loading device and the mold placement is the same, and the distance between each of the rotating shafts on the unloading device and its mold placement is the same; the rotating shafts on the loading device and the rotating shafts on the unloading device are respectively provided on both sides of the same mold placement.

[0016] The rotating shafts on the feeding device and the rotating shafts on the discharging device are respectively arranged on the front and rear sides of the same placing mold. The horizontal distance between each rotating shaft on the feeding device and the placing mold is the same, and the horizontal distance between each rotating shaft on the discharging device and the placing mold is the same; this ensures that the feeding device can transport the products synchronously and precisely to directly above the placing mold, guaranteeing the smooth processing of the products; similarly, the discharging device can synchronously and precisely transfer the processed products from the placing mold to the discharging assembly line, ensuring the smooth transfer of the processed products.

[0017] Preferably, a swinging assembly that rotates synchronously with each rotating shaft is provided at the end of each rotating shaft. The swinging assembly includes a first motor, a rotating member, and a mounting seat. The mounting seat is fixedly connected to the end of the rotating shaft. A first pin shaft is provided in the mounting seat, and the first pin shaft is installed in the mounting seat through a bearing. The rotating member is sleeved on the first pin shaft and rotates synchronously with it; the first motor is arranged on the side of the mounting seat and rotates synchronously with the first pin shaft. While the motor shaft of the first motor rotates, it drives the rotating member to rotate relative to the mounting seat. The axial direction of the first pin shaft is perpendicular to the axial direction of the rotating shaft.

[0018] When the swinging assembly works, the orientation of the clamping assembly will change; when the clamping assembly is in the initial state, the end face of the second cylinder facing away from the rotating member faces the front end face of the fuselage platform and they are arranged parallel to each other; when the first motor works, it drives the first pin shaft to rotate. While the first pin shaft rotates, the rotating member rotates relative to the mounting seat. When the feeding device transfers the products to the placing mold, at this time the products are between the two clamping arms on the clamping assembly. By controlling the rotating member to rotate through the first motor, the two clamping arms on the clamping assembly will move away from the surface of the products; during the rotation of the clamping assembly, the second cylinder rotates from the direction facing the placing mold to the direction facing the upper end face of the fuselage platform. Then the rotating assembly drives the rotating shaft to rotate. While the rotating shaft rotates, the clamping arms on the clamping assembly will not touch any of the placing molds; at this time, the clamping assembly rotates to the direction facing the feeding water flow line and the second cylinder faces the upper end face of the fuselage platform. When the products on the feeding water flow line are directly in front of the clamping assembly, the swinging assembly works to make the clamping assembly return to the initial state again, so that the clamping assembly can immediately clamp another group of products waiting to be processed on the feeding water flow line. After the swinging assembly drives the clamping assembly to rotate, there is no need to additionally control the clamping assembly to rise through the lifting assembly to make the clamping arms move away from the product surface. By quickly switching the orientation of the clamping assembly through the swinging assembly, the clamping assembly can conveniently clamp the products to be processed, greatly improving the feeding efficiency of the products. Similarly, the swinging assembly of the discharging device will work to change the orientation of the clamping assembly, thus facilitating the reliable clamping of the processed products by the clamping assembly.

[0019] Preferably, a clamping assembly fixedly connected to the rotating member is provided. The clamping assembly includes a second cylinder and a pair of clamping arms. The clamping arms are symmetrically distributed on both sides of the second cylinder, and the second cylinder is fixedly connected to the rotating member; the telescopic direction of the piston shaft of the second cylinder is parallel to the axial direction where the first pin shaft is located.

[0020] When the second cylinder works, the pair of clamping arms will approach or move away from each other, so that products can be quickly clamped or placed. The telescopic direction of the piston shaft of the second cylinder is parallel to the axial direction where the first pin shaft is located. In this way, when the first pin shaft rotates, the orientation of the second cylinder can be conveniently adjusted, thereby changing the position of the clamping arms and avoiding interference between the clamping arms and the placement mold, providing the reliability of the clamping assembly during operation.

[0021] Preferably, a discharge assembly line is provided directly below the blanking device. The discharge assembly line is arranged behind the placement mold and is parallel to the body platform.

[0022] The blanking device can conveniently transport the processed products to the discharge assembly line. The discharge assembly line is arranged inside the body platform and close to the blanking device. In this way, the time required for the blanking device to discharge materials is shorter, and there is no need to separately set up a discharge assembly line, which occupies less space.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The loading device and the unloading device of the present invention are both arranged on the moving plate. A plurality of placement molds are arranged on the body platform in parallel and at equal intervals. The loading device and the unloading device work synchronously; the rotating assembly on the loading device is connected to a plurality of clamping assemblies through a linkage assembly, and the clamping assemblies are synchronously controlled to approach or move away from the placement mold. In this way, the loading device can synchronously clamp a plurality of products to be processed from the feeding assembly line and place these products on the corresponding placement molds for processing; at the same time, the unloading device can synchronously clamp a plurality of processed products from the corresponding placement molds and transport these products to the discharge assembly line. While the loading device clamps the products from the feeding assembly line onto the placement mold, the discharging device clamps the processed products on the placement mold onto the discharge assembly line. The loading process and the unloading process of the products are carried out synchronously and do not interfere with each other, greatly improving the processing efficiency of the products.

[0025] 2. The orientation of the clamping assembly can be conveniently adjusted through the swinging assembly. After the feeding device places the product to be processed, the swinging assembly controls the clamping assembly to move away from the placement mold. Then, the rotating assembly controls the placement mold to rotate. Next, the swinging assembly controls the placement mold to face the product on the feeding pipeline. In this way, the clamping assembly can immediately clamp the new product to be processed without lifting, which speeds up the feeding speed. At the same time, the clamping assembly on the discharging device also adjusts its orientation through the swinging assembly, avoiding interference between the clamping assembly and the product or the placement mold during rotation and improving the reliability of product clamping.

[0026] 3. The lifting assembly, rotating assembly, linkage assembly, swinging assembly, and clamping assembly have a high degree of cooperation with each other and a simple structure. The product loading and unloading are reliable and the automation degree is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be further described below with reference to the embodiments shown in the drawings:

[0037] The lifting assembly 5 includes a pair of first cylinders 51 and a pair of support bases 52. The support bases 52 are fixedly connected to the body platform 1. The first cylinders 51 are installed on the support bases 52. The piston shaft of the first cylinder 51 is fixedly connected to the moving plate 2. While the first cylinder 51 is working, it drives the moving plate 2 to move up and down relative to the guide columns 3. The rotating assembly 6 includes a rotating motor 61 and a number of rotating shafts 62 arranged side by side and at equal intervals. Each of the rotating shafts 62 is installed on the moving plate 2 through a bearing. The rotating motor 61 is fixedly installed on the upper end surface of the moving plate 2. The rotating motor 61 is connected to the rotating shaft 62 arranged near the middle position of the moving plate 2 and drives it to rotate.

[0038] Each of the rotating shafts 62 is connected by a linkage assembly 7. The linkage assembly 7 includes a linkage pull plate 71, a positioning pin shaft 72, and a number of connecting members 73 corresponding one-to-one to the number of rotating shafts 62. One end of the connecting member 73 is fixedly connected to the rotating shaft 62, and the other end is hinged to the linkage pull plate 71 through the positioning pin shaft 72. When the rotary motor 61 drives one of the rotating shafts 62 to rotate, the remaining rotating shafts 62 rotate synchronously. While each rotating shaft 62 rotates, it drives the connecting member 73 to rotate. The rotation range of each connecting member 73 is between 120 - 150 degrees. The linkage pull plate 71 is provided with a number of mounting notches 75 for mounting the connecting members 73. The number of the mounting notches 75 corresponds one-to-one to the connecting members 73. The mounting notches 75 are arranged side by side and equidistantly on the linkage pull plate 71. The end face of the linkage pull plate 71 facing away from the rotating shaft 62 is always arranged parallel to the front end face of the fuselage platform 1. The rotating shafts 62 on the loading device 10 and the unloading device 11 are both arranged side by side and equidistantly. The distance between each rotating shaft 62 on the loading device 10 and the front end face of the fuselage platform 1 is the same. The distance between each rotating shaft 62 on the unloading device 11 and the front end face of the fuselage platform 1 is the same.

The distance between each first through hole 74 on the unloading device 11 and the front end face of the fuselage platform 1 is the same. The number of the rotating shafts 62 and the first through holes 74 both corresponds one-to-one to the number of the placing molds 4. The placing molds 4 are arranged side by side and equidistantly on the fuselage platform 1. The distance between each placing mold 4 and the front end face of the fuselage platform 1 is the same. A rotating shaft 62 is provided between any two placing molds 4. The loading device 10 is arranged in front of the placing mold 4, and the unloading device 11 is arranged behind the placing mold 4. The distance from the rotating shaft 62 on the loading device 10 to the front end face of the fuselage platform 1 is closer than the distance from the placing mold 4 to the front end face of the fuselage platform 1. While the rotary motor 61 drives the rotating shaft 62 to rotate, the connecting member 73 drives the linkage pull plate 71 to approach or move away from the placing mold 4. The distance from the rotating shaft 62 on the unloading device 11 to the front end face of the fuselage platform 1 is farther than the distance from the placing mold 4 to the front end face of the fuselage platform 1. While the rotary motor 61 drives the rotating shaft 62 to rotate, the connecting member 73 drives the linkage pull plate 71 to approach or move away from the placing mold 4.

[0039] Each of the rotating shafts 62 is disposed on the same side as the adjacent placing mold 4 and they are in one-to-one correspondence. The distance between each rotating shaft 62 on the loading device 10 and the placing mold 4 is the same, and the distance between each rotating shaft 62 on the unloading device 11 and the placing mold 4 is the same; the rotating shafts 62 on the loading device 10 and the rotating shafts 62 on the unloading device 11 are respectively disposed on both sides of the same placing mold 4. A swing assembly 8 that rotates synchronously with it is provided at the end of each rotating shaft 62. The swing assembly 8 includes a first motor 81, a rotating member 82, and a mounting seat 83. The mounting seat 83 is fixedly connected to the end of the rotating shaft 62. A first pin shaft 84 is provided in the mounting seat 83. The first pin shaft 84 is installed in the mounting seat 83 through a bearing. The rotating member 82 is sleeved on the first pin shaft 84 and rotates synchronously with it; the first motor 81 is disposed on the side of the mounting seat 83 and rotates synchronously with the first pin shaft 84. While the motor shaft of the first motor 81 rotates, it drives the rotating member 82 to rotate relative to the mounting seat 83. The axial direction of the first pin shaft 84 is perpendicular to the axial direction of the rotating shaft 62. A clamping assembly 9 fixedly connected to it is provided on the rotating member 82. The clamping assembly 9 includes a second cylinder 91 and a pair of clamping arms 92. The clamping arms 92 are symmetrically distributed on both sides of the second cylinder 91. The second cylinder 91 is fixedly connected to the rotating member 82; the telescopic direction of the piston shaft of the second cylinder 91 is parallel to the axial direction where the first pin shaft 84 is located. An unloading conveyor line 12 is provided directly below the unloading device 11. The unloading conveyor line 12 is disposed behind the placing mold 4 and is parallel to the body platform 1.

[0040] The specific operation process of this embodiment is as follows. By default, in the initial state, the moving plate 2 is at a low position and close to the upper end surface of the fuselage platform 1. The clamping assembly 9 on the feeding device 10 faces the feeding assembly line, and the second air cylinder 91 faces the upper end surface of the fuselage platform 1. The clamping assembly 9 on the discharging device 11 faces the placement mold 4, and the second air cylinder 91 faces the upper end surface of the fuselage platform 1. When the first group of products to be processed on the feeding assembly line is transported in front of the clamping assembly 9, the swinging assemblies 8 on the feeding device 10 and the discharging device 11 work simultaneously. Then, the second air cylinder 91 on the feeding device 10 will face the products to be processed and clamp the products. The second air cylinder 91 on the discharging device 11 will face the placement mold 4 and be in a waiting state. Since there is no product being processed on the placement mold 4 at this time, the piston rod of the second air cylinder 91 does not need to perform telescopic work. Then, the lifting assembly 5 controls the moving plate 2 to rise. When the products clamped by the feeding device 10 are higher than the placement mold 4, the moving plate 2 stops rising. Then, the rotating assemblies 6 on the feeding device 10 and the discharging device 11 work synchronously. Since each of the rotating shafts 62 is connected to each other through the linkage assembly 7, each of the rotating shafts 62 will rotate synchronously. The rotating assembly 6 on the feeding device 10 positions the first group of products to be processed directly above the placement mold, and the rotating assembly 6 on the discharging device 11 positions the clamping assembly 9 directly above the discharging assembly line 12. Then, the lifting assembly 5 controls the moving plate 2 to move down. The feeding device 10 places the first group of products to be processed onto the placement mold 4, and the clamping assembly 9 on the discharging device 11 moves closer to the discharging assembly line 12.

[0041] After the first group of products is processed, the swing assembly 8 of the loading device 10 controls the clamping arm 92 to move away from the placement mold 4, and the second cylinder 91 faces the upper end surface of the fuselage platform 1; at the same time, the swing assembly 8 of the unloading device 11 controls the second cylinder 91 to face the upper end surface of the fuselage platform 1; then the rotating assemblies 6 of the loading device 10 and the unloading device 11 work synchronously. The loading device 10 controls the clamping assembly 9 to face the feeding assembly line, and the unloading device 11 controls the clamping assembly 9 to face the placement mold 4; when the second group of products to be processed is in front of the clamping assembly 9 of the loading device 10, the swing assembly 8 of the loading device 10 controls the second cylinder 91 to face the feeding assembly line and clamp the second group of products to be processed, and the swing assembly 8 of the unloading device 11 controls the second cylinder 91 to face the placement mold 4 and clamp the first group of processed products; then the lifting assembly 5 controls the loading device 10 and the unloading device 11 to rise synchronously. Then, the rotating assemblies 6 on the loading device 10 and the unloading device 11 work synchronously. The loading device 10 positions the second group of products to be processed directly above the placement mold 4, and the unloading device 11 positions the first group of processed products directly above the discharging assembly line 12; then the lifting assembly 5 moves downward. The loading device 10 places the second group of products to be processed onto the placement mold 4, and the unloading device 11 places the first group of processed products onto the discharging assembly line 12.

[0042] Then, the swing assemblies 8 and the rotating assemblies 6 on the loading device 10 and the unloading device 11 work in sequence. The loading device 10 is ready to grab the third group of products to be processed, and the unloading device 11 is ready to grab the second group of processed products. By analogy and repeating the above steps, the loading and unloading process of the products can be continuously carried out.
