Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe manufacturing equipment, and in particular to a synchronous loading and unloading device and a mandrel processing system. Background Art

[0002] In the production process of steel pipes, the mandrel needs to be driven to different workstations for different process treatments. The equipment used to drive the mandrel to move is a loading device and an unloading device. The traditional operation mode of the two devices is: after the unloading device rotates one circle, the loading device rotates another circle, that is, the loading device and the unloading device are not operated at the same time, which requires a lot of time.

[0003] In order to save time, in the prior art known to the inventor, an electrical control device is provided on each of the loading device and the unloading device, so that the loading device and the unloading device rotate simultaneously to save time. However, there are unstable factors in electrical control, and there is a risk of interference between the loading device and the unloading device. Therefore, the loading device can only start to move after the unloading device rotates to a safe position and stops. Specifically, vertical downward is recorded as 0°, and the base position of the unloading device is at 30°. When the unloading device pulls the mandrel out of the limit rack and lifts the mandrel to a safe position of 180°, the loading device starts to move from the waiting position of 145°. During the process of the unloading device rotating from 30° to 180°, the loading device cannot do any action, which greatly affects the production efficiency. Summary of the invention

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] See also Figure 1 and Figure 7 As shown, the present invention provides a synchronous loading and unloading device, comprising: a base 10; a linkage assembly 20, which is arranged on the base 10, and the linkage assembly 20 includes a plurality of gears that are mutually transmission-connected, and the adjacent gears are meshed and connected; a loading assembly, including a loading arm 31, the loading arm 31 is connected to at least one gear, and the loading arm 31 is configured to be driven by the gear to rotate and drive the material to move from the first position to the second position; and a unloading assembly, including a unloading arm 41, the unloading arm 41 is connected to at least another gear, and the unloading arm 41 is configured to be driven by the gear to rotate and drive the material to move from the first position to the second position. The animal feed moves from the second position to the third position; the loading arm 31 and the lower feeding arm 41 rotate synchronously through gears, and part of the rotation path of the loading arm 31 overlaps with part of the rotation path of the lower feeding arm 41 to form an overlapping area. In the rotation path of the loading arm 31, the other areas except the overlapping area are the loading staggered areas, and in the rotation path of the lower feeding arm 41, the other areas except the overlapping area are the lower feeding staggered areas. When the loading arm 31 is located in the overlapping area, the lower feeding arm 41 is located in the lower feeding staggered area, and when the lower feeding arm 41 is located in the overlapping area, the loading arm 31 is located in the loading staggered area.

[0029] In this embodiment, the overlapping area is the area where the loading arm 31 and the unloading arm 41 may interfere. Through the design of the relative positions of the loading arm 31 and the unloading arm 41, the loading arm 31 and the unloading arm 41 do not enter the overlapping area simultaneously, so that they are independent of each other and do not interfere with each other, ensuring the feasibility of their simultaneous operation. The loading arm 31 and the unloading arm 41 rotate simultaneously through the linkage of gears, that is, the synchronous movement of the loading arm 31 and the unloading arm 41 is achieved by one drive, and the situation where one stops and the other moves is prohibited. Compared with the traditional loading device or unloading device, there is no need to wait, thus saving time and improving efficiency. When the loading arm 31 rotates in the direction of the first position, the unloading arm 41 can rotate in the direction of the second position. When the loading arm 31 rotates from the first position to the second position, the unloading arm 41 can rotate from the second position to the third position, so that while the loading arm 31 drives a material to move, the unloading arm 41 can also drive a material to move, and thus two materials can be in the process of process treatment at the same time, improving the processing efficiency of the materials.

[0030] In this embodiment, gear meshing transmission is adopted. Compared with the structure of gears cooperating with a conveyor belt, on the one hand, in this embodiment, there is no need to consider the length and shape of the conveyor belt. The conveyor belt requires at least two gears in the same straight line for transmission, while the multiple gears in this embodiment can be flexibly arranged, that is, the positions of the gears can be arbitrarily arranged according to the position requirements of the loading arm 31 and the unloading arm 41; on the other hand, the installation of gears is more convenient. After finding the installation positions of each gear, transmission can be achieved, and there is no need to add the step of installing the conveyor belt, improving the installation efficiency; on the further hand, in this embodiment, since the outer teeth of each gear are meshed, the angle difference between the loading arm 31 and the unloading arm 41 has been determined during the installation process, and there will be no loosening and skipping teeth of the conveyor belt and stretching and deformation of the conveyor belt, so the angle deviation between the loading arm 31 and the unloading arm 41 will not be affected, ensuring more stable transmission.

[0031] The loading component and the unloading component are forced to be synchronized through the mechanical structure of the coupling component. Compared with the existing technology where electrical control is used separately, the situation where interference occurs when the loading arm 31 and the unloading arm 41 are running due to electrical control failure is avoided, improving the safety of the synchronous loading and unloading device and achieving obstacle-free transmission.

[0032] In another embodiment, the lengths of the loading arm 31 and the unloading arm 41 are the same, and their rotation paths are circles with the same diameter, so that the proportion of the overlapping area in the rotation path of the loading arm 31 is equal to the proportion of the overlapping area in the rotation path of the unloading arm 41, making the relative positions of the loading arm 31 and the unloading arm 41 and the design of the linkage component 20 easier and more feasible.

[0033] Combined with reference to Figure 1and Figure 7 As shown in Figure 7 , in an embodiment of the present invention, the linkage assembly 20 includes a first gear 21, a second gear 22, a third gear 23, a fourth gear 24, and a fifth gear 25 that are sequentially meshed and connected. One end of the first gear 21 is connected to one end of the loading arm 31, and one end of the fifth gear 25 is connected to one end of the unloading arm 41. The central axis of the first gear 21 and the central axis of the fifth gear 25 are in the same plane, which is the first plane. The central axes of the second gear 22, the third gear 23, and the fourth gear 24 are in the same plane, which is the second plane. The first plane is higher than the second plane.

[0034] In this embodiment, the second gear 22, the third gear 23, and the fourth gear 24 are only used for transmission and are arranged side by side in the second plane. The first gear 21 is used for the installation of the loading arm 31, and the fifth gear 25 is used for the installation of the unloading arm 41. Therefore, the first gear 21 and the fifth gear 25 are arranged in a vertically offset manner with the second gear 22, the third gear 23, and the fourth gear 24, making the layout of the five gears more reasonable and enabling the first gear 21 and the fifth gear 25 to be located at a certain height, so that the loading arm 31 and the unloading arm 41 have a larger operable space. Furthermore, the length design of the loading arm 31 only needs to consider the distance between the first position and the second position and the interference problem with the unloading arm 41, without considering the diameter and the height where the first gear 21 is located. The same applies to the length design of the unloading arm 41. The design of an odd number of gears is used to ensure that the first gear 21 and the fifth gear 25 rotate in the same direction, and thus the loading arm 31 and the unloading arm 41 rotate in the same direction.

[0035] In another embodiment, both the first plane and the second plane are horizontal planes, making the first gear 21, the second gear 22, the third gear 23, the fourth gear 24, and the fifth gear 25 form a symmetrical structure. This symmetrical structure takes the perpendicular line perpendicular to the central axis of the third gear 23 as the symmetry line, making the linkage assembly 20 formed by the five gears more stable, and thus making the movements of the loading arm 31 and the unloading arm 41 more stable.

[0036] In another embodiment, the diameters of the first gear 21, the second gear 22, the third gear 23, the fourth gear 24, and the fifth gear 25 are the same, making the rotation speeds of the loading arm 31 and the unloading arm 41 the same, so that they always maintain a fixed relative angle during the movement process, avoiding interference between them.

[0037] Combined with reference to Figure 1 and Figure 7As shown in the figure, in one embodiment of the present invention, the projected length of the line connecting the centers of the first gear 21 and the second gear 22 on the horizontal plane is a1, the sum of the radii of the first gear 21 and the second gear 22 is b1, a1 < b1. The projected length of the line connecting the centers of the fifth gear 25 and the fourth gear 24 on the horizontal plane is a2, the sum of the radii of the fifth gear 25 and the fourth gear 24 is b2, and a2 < b2.

[0038] In this embodiment, the relative arrangement of the first gear 21 and the second gear 22 and the relative arrangement of the fifth gear 25 and the fourth gear 24 make the spatial structure of the linkage assembly 20 more compact, reduce the space occupied by the linkage assembly 20, and improve the space utilization rate.

[0039] Specifically, as Figure 6 shown, the first gear 21 is located in the upper left of the second gear 22, and the fifth gear 25 is located in the upper right of the fourth gear 24.

[0040] In another embodiment, the first gear 21, the second gear 22, the third gear 23, the fourth gear 24, and the fifth gear 25 are located in the same vertical plane.

[0041] Combined with reference to Figure 1 and Figure 7 shown, in one embodiment of the present invention, the synchronous loading and unloading device further includes a main driver 91 and a standby driver 92. The main driver 91 is drivingly connected to one gear, and the standby driver 92 is drivingly connected to another gear.

[0042] In this embodiment, the main driver 91 serves as the main driving machine to drive the linkage assembly 20 to act. When the main driver 91 ages or breaks down, it is possible to select to enable the standby driver 92 to repair or replace the main driver 91, ensure the continuous operation of the synchronous loading and unloading device, save the time required for shutdown repair or replacement when the main driver 91 cannot be used, reduce the impact of the shutdown of the main driver 91 on the synchronous loading and unloading device, and thus ensure the production efficiency.

[0043] Compared with the prior art solution of using two electrical control devices to control the loading device and the unloading device respectively, in this embodiment, only one driver needs to be started at the same time, that is, changing from the dual-device drive of the prior art to a single-device drive, optimizing the program and saving the spare parts cost.

[0044] Combined with reference to Figure 1 and Figure 7 shown, in one embodiment of the present invention, the main driver 91 includes a motor and a reduction gearbox, and the minimum torque output by the reduction gearbox is M 减 , M 减 = M 电×Reduction gearbox transmission ratio / minimum safety factor, M 电 is the motor torque, and the minimum torque required for the operation of the loading component and the unloading component is M 总 , M 减 ≥M 总 , M 总 = M1 + M2 + M3 + M4, where M1 is the minimum torque output by the main driver 91 to drive the material when there is material on the loading component, M1 = m 物 g×Lsin90°, m 物 is the mass of the material, L is the radius of the rotation path of the loading arm 31, M2 is the minimum torque output by the main driver 91 to drive the loading component, M2 = m 上 g×Lsin90°, m 上 is the mass of the loading component, M3 is the minimum torque output by the main driver 91 to drive the material when there is no material on the unloading component, M3 = 0, M4 is the minimum torque output by the main driver 91 to drive the unloading component, M4 = m 下 g×Lsinα, m 下 is the mass of the unloading component, and α is the angle between the unloading arm 41 and the vertical line.

[0045] In this embodiment, the minimum torque required for the operation of the loading component and the unloading component should be less than or equal to the minimum torque output by the reducer to ensure that the main driver 91 can drive the loading component and the unloading component smoothly. When the loading arm 31 is in the horizontal position and the loading tray 32 is in the first position, the force on the loading arm 31 is the largest; when the loading arm 31 is in the vertical position and the loading tray 32 is below the loading arm 31, the force on the loading arm 31 is the smallest, approaching 0; similarly, the force on the unloading arm 41 is the same as that on the loading arm 31. Therefore, when the force on the loading arm 31 is the largest, the force on the unloading arm 41 is the smallest. This embodiment takes this state as the standard and lists the relational expressions.

[0046] Specifically, M 电 is 471.1 N·m, the reduction gearbox transmission ratio is 49, the minimum safety factor ≤ 1.7, m 物 is 1430 kg, L is 700 mm, m 上 and m 下 are the same, being 388 kg, α is 4° - 10°, preferably 4°, and the corresponding angle of α is marked as Figure 7 shown.

[0047] In another embodiment, the standby driver 92 also includes a motor and a reduction gearbox, and the design is the same as that of this embodiment to ensure that when the standby driver is enabled, it reaches the same speed and effect as the main driver 91.

[0048] Specifically, the motor rotates at a predetermined rotational speed curve, enabling the feeding component and the discharging component to have smooth acceleration, reducing the impact between the two, and improving the smoothness of material transfer in and out of the first position, the second position, or the third position. Compared with the feeding device and the discharging device in the prior art, the synchronous feeding and discharging device in this embodiment has an increased operating speed and improved operating stability.

[0049] Referring to Figure 1 and Figure 7 As shown, in an embodiment of the present invention, the rotational upward movement of the feeding arm 31 and the rotational downward movement of the discharging arm 41 are carried out simultaneously, and the rotational downward movement of the feeding arm 31 and the rotational upward movement of the discharging arm 41 are carried out simultaneously.

[0050] In this embodiment, through the staggered timing design of rotational upward and rotational downward movements, the potential energy of the rotational downward movement of the feeding arm 31 can be converted into the kinetic energy of the rotational upward movement of the discharging arm 41, and the potential energy of the rotational downward movement of the discharging arm 41 can also be converted into the kinetic energy of the rotational upward movement of the feeding arm 31, thereby reducing the load on the motor and saving energy consumption. As Figure 7 shown, the rotational path of the feeding arm 31 is the left circle, and the rotational path of the discharging arm 41 is the right circle. The overlapping area is within the rotational downward area of the feeding arm 31 and the rotational upward area of the discharging arm 41. The feeding staggered area is within the rotational upward area of the feeding arm 31, and the discharging staggered area is within the rotational downward area of the discharging arm 41. To avoid the feeding arm 31 and the discharging arm 41 entering the overlapping area simultaneously, the relative positions of the feeding arm 31 and the discharging arm 41 are set such that when the feeding arm 31 rotates upward, the discharging arm 41 rotates downward, and when the feeding arm 31 rotates downward, the feeding arm 31 rotates upward, avoiding interference between the two.

[0051] Referring to Figure 1 and Figure 7 shown, in an embodiment of the present invention, a relative angle is maintained between the feeding arm 31 and the discharging arm 41, and the relative angle is 80° - 86°.

[0052] In this embodiment, through calculation and verification, it is obtained that when the relative angle between the feeding arm 31 and the discharging arm 41 is maintained at 80° - 86°, the two will not interfere with each other. If the relative angle exceeds this range, it will cause interference between the feeding arm 31 and the discharging arm 41, and further cause direct damage to the synchronous feeding and discharging device. The relative angle is preferably 80°.

[0053] Referring to Figure 1 and Figure 7 shown, in an embodiment of the present invention, the feeding component further includes a feeding tray 32 rotatably connected to the feeding arm 31, and the supporting surface of the feeding tray 32 always faces upward. The discharging component further includes a discharging tray 42 rotatably connected to the discharging arm 41, and the supporting surface of the discharging tray 42 always faces upward.

[0054] In this embodiment, both the loading tray 32 and the unloading tray 42 support and move the material, that is, the material is always located above the loading tray 32 or the unloading tray 42. Therefore, during the rotation of the loading arm 31 and the unloading arm 41, the supporting surfaces of the loading tray 32 and the unloading tray 42 are always kept facing upward to prevent the material from detaching from the loading tray 32 or the unloading tray 42.

[0055] Refer to Figure 1 and Figure 7 As shown in the figure, in an embodiment of the present invention, the loading assembly further includes a first fixed gear 34 and at least one first loading gear 33 provided on the loading arm 31. The first fixed gear 34 is fixedly connected to the base 10, the first fixed gear 34 is rotatably connected to the loading arm 31, the first fixed gear 34 is in transmission connection with the first loading gear 33, and one first loading gear 33 is connected to the loading tray 32 to drive the loading tray 32 to rotate relative to the loading arm 31; the unloading assembly further includes a second fixed gear 44 and at least one first unloading gear 43 provided on the unloading arm 41. The second fixed gear 44 is fixedly connected to the base 10, the second fixed gear 44 is rotatably connected to the unloading arm 41, the second fixed gear 44 is in transmission connection with the first unloading gear 43, and one first unloading gear 43 is connected to the unloading tray 42 to drive the unloading tray 42 to rotate relative to the unloading arm 41.

[0056] In this embodiment, the sum of the number of the first fixed gear 34 and the first loading gears 33 is odd to ensure that the rotation direction of the first loading gear 33 is opposite to the rotation direction of the loading arm 31, so as to realize the function of keeping the supporting surface of the loading tray 32 always facing upward; during the rotation of the loading arm 31, the first fixed gear 34 is fixed relative to the base 10 and rotates relative to the loading arm 31, so that during the rotation of the loading arm 31, the first loading gear 33 can rotate relative to the loading arm 31 by means of transmission. The sum of the number of the second fixed gear 44 and the first unloading gears 43 is odd to ensure that the rotation direction of the first unloading gear 43 is opposite to the rotation direction of the unloading arm 41, so as to realize the function of keeping the supporting surface of the unloading tray 42 always facing upward; during the rotation of the unloading arm 41, the second fixed gear 44 is fixed relative to the base 10 and rotates relative to the unloading arm 41, so that during the rotation of the unloading arm 41, the first unloading gear 43 can rotate relative to the loading arm 31 by means of transmission.

[0057] In another embodiment, there is one first loading gear 33, and it is not adjacent to the first fixed gear 34. The loading assembly further includes a second loading gear 35 which is located between the first loading gear 33 and the first fixed gear 34. The first fixed gear 34, the second loading gear 35 and the first loading gear 33 are sequentially meshed and connected, and the diameters of the three are the same. Moreover, the diameters of the three are the same as those of all the gears of the linkage assembly 20, so as to ensure that the rotation speed of the loading disk 32 is the same as that of the loading arm 31, and further ensure that the supporting surface of the loading disk 32 always faces upward and will not be affected by the rotation of the loading arm 31. There is one first unloading gear 43, and it is not adjacent to the second fixed gear 44. The unloading assembly further includes a second unloading gear 45 which is located between the first unloading gear 43 and the second fixed gear 44. The second fixed gear 44, the second unloading gear 45 and the first loading gear 33 are sequentially meshed and connected, and the diameters of the three are the same. Moreover, the diameters of the three are the same as those of all the gears of the linkage assembly 20, so as to ensure that the rotation speed of the unloading disk 42 is the same as that of the unloading arm 41, and further ensure that the supporting surface of the unloading disk 42 always faces upward and will not be affected by the rotation of the unloading arm 41.

[0058] Referring to Figure 1 and Figure 7 As shown, the present invention further provides a device, including: a loading and placing device including a loading station 60 which is configured to be able to place the mandrel 50 before rolling; a rolling device including a rolling station 70 and a rolling mill, the rolling station 70 is configured to be able to place the mandrel 50, and the rolling mill is configured to be able to roll the mandrel 50 on the rolling station 70; an unloading and placing device including an unloading station 80 which is configured to be able to place the rolled mandrel 50; and the above-mentioned synchronous loading and unloading device. The loading station 60 and the rolling station 70 are located on the rotation path of the loading assembly, and the loading assembly is configured to be able to drive the mandrel 50 to move from the loading station 60 to the rolling station 70. The rolling station 70 and the unloading station 80 are located on the rotation path of the unloading assembly, and the unloading assembly is configured to be able to drive the mandrel 50 to move from the rolling station 70 to the unloading station 80.

[0059] In this embodiment, the processing process of the mandrel 50 is as follows: After the mandrel 50 is placed on the loading station 60, it is moved from the loading station 60 to the rolling station 70 by the loading arm 31. The mandrel 50 is rolled by the rolling mill. The rolled mandrel 50 is moved from the rolling station 70 to the unloading station 80 by the unloading arm 41, and the processing of the mandrel 50 is completed. The loading station 60, the rolling station 70 and the unloading station 80 are arranged in a pipeline-like position, so that the loading arm 31 and the unloading arm 41 can cooperate with each other to drive the mandrel 50 to move sequentially between the stations, and further make the processing of the mandrel 50 scientific and orderly.

[0060] During the rolling process of the mandrel 50, the loading arm 31 moves from the rolling station 70 to the loading station 60, ready to receive the next mandrel 50, and the unloading arm 41 moves from the unloading station 80 to the rolling station 70, ready to receive the rolled mandrel 50; while the rolled mandrel 50 is driven to the unloading station 80 by the unloading arm 41, the loading arm 31 drives the next mandrel 50 before rolling to the rolling station 70. The entire synchronous loading and unloading device can move two mandrels 50 at the same time, effectively improving production efficiency. Specifically, after synchronizing the loading assembly and the unloading assembly through the linkage assembly 20, the two cycles of the two sets of equipment can be shortened to the cycle of one equipment, so that the mandrel 50 can wait in front of the rolling station 70 in advance, thereby improving production efficiency.

[0061] See also Figure 1 and Figure 7 As shown, in one embodiment of the present invention, the distance between the loading station 60 and the rolling station 70 is equal to the distance between the rolling station 70 and the unloading station 80, and the length of the loading arm 31 is the same as the length of the unloading arm 41.

[0062] In this embodiment, the length of the loading arm 31 is equal to the distance between the loading station 60 and the rolling station 70, so that the loading arm 31 can smoothly lift the mandrel 50 on the loading station 60 and smoothly move the mandrel 50 to the rolling station 70; the length of the unloading arm 41 is equal to the distance between the rolling station 70 and the unloading station 80, so that the unloading arm 41 can smoothly lift the mandrel 50 on the rolling station 70 and smoothly move the mandrel 50 to the unloading station 80. The station distance corresponds to the length of the loading arm 31 and the unloading arm 41, ensuring that the synchronous loading and unloading device can operate smoothly and realize the function of moving the mandrel 50.

[0063] Through the above arrangement, the rotation path of the upper material arm 31 and the rotation path of the lower material arm 41 are completely the same, which facilitates the arrangement of the relative angle between the upper material arm 31 and the lower material arm 41 to avoid interference between the two.

[0064] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the present invention combines the loading assembly and the unloading assembly together through a linkage assembly, forms a linkage effect through gears, and drives the loading assembly and the unloading assembly to rotate at the same time. By designing that the two do not enter the overlapping area at the same time, there is no interference between the two. By utilizing the loading staggered area and the unloading staggered area, when the loading assembly is located in the overlapping area, the unloading assembly is located in the unloading staggered area, and when the unloading assembly is located in the overlapping area, the loading assembly is located in the loading staggered area, thereby ensuring that the loading assembly and the unloading assembly are independent of each other and can move synchronously, saving time, and improving production efficiency. Specifically, the efficiency of one cycle of loading and unloading rotation is increased by 2s.
