Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding of mixers, in particular to an automatic feeding system for mixers. Background Technique

[0002] Powder metallurgy is a process of using metal powders (or mixtures of metal powders and non-metal powders) as raw materials to manufacture metal materials, composite materials and various types of products through forming and sintering. With the development of powder metallurgy technology, the performance requirements of powder metallurgy products are also constantly improving.

[0003] As disclosed in the Chinese patent document with the publication number CN202988264U, a powder forming product processing device is disclosed. The processing device is arranged on a workbench, and the processing device includes a control mechanism and a picking mechanism, a deburring mechanism, a conveying mechanism and a detection mechanism respectively connected to the control mechanism; the picking mechanism is arranged on one side of the workbench, and the deburring mechanism and the conveying mechanism are sequentially arranged on one side of the workbench relative to the picking movement direction of the picking mechanism.

[0004] Although the above solution can simplify the post-processing work of formed products, it does not achieve automation in the powder filling process. In the prior art, powder feeding is generally carried out manually, and there will be contact between the limbs and the mold during this process, which increases the danger of operators. Moreover, due to manual feeding, the powder filling will be uneven.

[0005] Especially in some production processes with relatively larger sizes, the amount of metal powder required is very large, and a mixer is needed for mixing. In order to improve efficiency, the capacity of a mixer can even accommodate 500 kilograms of metal powder. And manual feeding can usually only feed about 20 kilograms at a time, resulting in relatively low feeding efficiency. Workers' long-term high-intensity labor is also likely to cause physical strain.

Detailed implementation manners

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 8 , in the embodiments of the present invention, an automatic feeding system for a mixer includes: a material tank 70 containing the materials required by the mixer 80, and a gripping hook 71 is provided at the upper part of the material tank 70; a loading and unloading platform 10 for loading or unloading the material tank 70; a gripping mechanism 20 for gripping or releasing the material tank 70; a truss mechanism 30 for installing and driving the gripping mechanism 20 to move in position; and an unloading mechanism 60 for docking the material tank 70 with the mixer 80 and releasing the materials in the material tank 70 into the mixer 80; wherein, the gripping mechanism 20 is installed at the driving end of the truss mechanism 30, and the truss mechanism 30 operates to drive the gripping mechanism 20 to transport the material tank 70 into the loading and unloading platform 10 or the unloading mechanism 60; and a control module is further included, and the control module is electrically connected to the loading and unloading platform 10, the gripping mechanism 20, the truss mechanism 30 and the unloading mechanism 60 respectively to perform automatic operation control.

[0039] Specifically, in order to move the material tank 70, a truss mechanism 30 can be set up to drive the grasping mechanism 20 in the x, y, and z axes. Thus, under the control of the control module, the grasping mechanism 20 can perform automated movement control on the material tank 70 loaded with a large amount of metal powder, enabling it to be transported between the loading and unloading platform 10 and the discharging mechanism 60. Furthermore, a large amount of materials can be transported into the mixer 80 at one time for corresponding mixing operations, improving the feeding speed of the mixer 80.

[0040] Secondly, in order to prevent accidents during the movement of the material tank 70 from causing collisions with other devices or components, a protective net can also be set up on the movement route of the material tank 70, such as using a high-strength wire mesh. Since the feeding efficiency of the automatic feeding system is very high, in order to cooperate with the automatic feeding system, multiple mixer 80 workstations can be set up, and corresponding discharging mechanisms 60 can be respectively set above the multiple mixer 80 workstations, enabling the discharging mechanism 60 to dock the material tank 70 to each mixer 80.

[0041] Furthermore, two groups of loading and unloading platforms 10 can also be respectively set up, so that one group is responsible for the feeding operation of the material tank 70 loaded with materials, and the other group is responsible for the discharging operation of the material tank 70 emptied of materials, thereby further improving the efficiency of the entire automatic feeding system. Moreover, the control module can be provided with corresponding sensors to sense and control each step, making the entire system operate smoothly.

[0042] As Figure 2 and Figure 3 shown, preferably, the loading and unloading platform 10 is provided with a calibration mechanism 11, and the calibration mechanism 11 is used to calibrate the position of the material tank 70 on the loading and unloading platform 10 to facilitate its grasping by the grasping mechanism 20; the calibration mechanism 11 is provided with a calibration frame 12, a rolling platform 13, a calibration baffle 14, and a side pushing device 15. The calibration baffle 14 is fixedly connected to the calibration frame 12 and limits the material tank 70. The rolling platform 13 is rotatably connected to the calibration frame 12, enabling the material tank 70 placed on the rolling platform 13 to move forward and backward a certain distance; the side pushing device 15 is installed on the calibration frame 12 and is located at both ends of the rolling platform 13 to laterally push the material tank 70, enabling the material tank 70 to move axially along the rolling platform 13 a certain distance.

[0043] Specifically, since both the material tank 70 itself and the materials contained therein are relatively heavy, even reaching five hundred kilograms, for the operation of the material tank 70, mechanical equipment such as forklifts can be used for assistance. When the forklift lifts the material tank 70 to the loading and unloading platform 10, its placement position is necessarily not precise enough. Therefore, a calibration mechanism 11 needs to be set up to calibrate the placement position of the material tank 70 so that it is precisely placed at the preset position. The calibration baffle 14 is preferably installed on the calibration platform behind the rolling platform 13, so as to limit the material tank 70 when it is pushed backward, making the material tank 70 in the front-back direction in the preset position. The rolling platform 13 is preferably arranged with multiple rolling axle bars, and the rolling axle bars are rotatably connected to the calibration frame 12, so that the material tank 70 placed on the rolling platform 13 can be pushed, thereby adjusting the position in the front-back direction.

[0044] As Figure 3 shown, preferably, the side pushing device 15 is provided with a side pushing cylinder 16 and a side pushing plate 17. The side pushing cylinder 16 is fixedly connected to the calibration frame 12, and the side pushing plate 17 is fixedly connected to the piston rod of the side pushing cylinder 16, so as to push the material tank 70 under the drive of the side pushing cylinder 16.

[0045] Specifically, side pushing devices 15 can be respectively installed on the calibration frames 12 at both ends of the rolling platform 13, so that it can be pushed from both ends of the rolling platform 13 respectively, changing the position of the material tank 70 in the axial direction of the rolling platform 13, so that it can be moved to the correct preset position. Since rolling axle bars are provided in the front-back direction of the material tank 70, making the front-back movement of the material tank 70 relatively easy and relatively easy to align with the preset position. In the left-right direction, it is not convenient to move the material tank 70. Therefore, a special side pushing device 15 can be set up, using the power provided by the cylinder to make the material tank 70 move a certain distance left and right to reach the preset position.

[0046] As Figure 2 and Figure 3 shown, preferably, in order to ensure that the material tank 70 reaches the preset position, confirmation can be carried out. For example, the loading and unloading platform 10 is also provided with a confirmation cylinder 18 and a confirmation guide post 19. The confirmation cylinder 18 is fixedly connected to the calibration frame 12 and installed under the rolling platform 13. The confirmation guide post 19 is fixedly connected to the piston rod of the confirmation cylinder 18, and under the drive of the confirmation cylinder 18, it can penetrate into the guiding positioning hole 72 at the bottom of the material tank 70, so as to ensure that the material tank 70 is in the preset position.

[0047] Specifically, the confirmation cylinder 18 is preferably a magnetic cylinder with a magnetic induction switch or a magnetic induction sensor, so as to detect the moving position of the piston rod and feedback it to the control module, so that through the moving distance or moving position of the piston rod, it can be calculated whether the placement position of the material tank 70 is correct.

[0048] For example, when the piston rod extends upward to a relatively long stroke, it indicates that the guide post 19 has been correctly inserted into the guide positioning hole 72, and the position of the material tank 70 is correctly placed. When the extension stroke of the piston rod is short and it cannot extend further, it indicates that the guide post 19 has not been correctly inserted into the guide positioning hole 72, but abuts against other components at the bottom of the material tank 70, indicating that the position of the material tank 70 is placed incorrectly and needs to be readjusted.

[0049] In order to more accurately sense and confirm the placement position of the material tank 70, it is preferable to set multiple groups of confirmation cylinders 18 and confirmation guide posts 19. For example, two groups are set at the diagonal positions at the bottom of the material tank 70 to respectively confirm the placement position of the material tank 70. Or four groups can also be directly set at the four corners at the bottom of the material tank 70 for more accurate confirmation.

[0050] As Figures 4 to 6 shown, preferably, the truss mechanism 30 is provided with a horizontal axis assembly 31, a vertical axis assembly 40 and a vertical axis assembly 50. The horizontal axis assembly 31 is provided with a horizontal axis bracket 32, and the horizontal axis bracket 32 is used to support the entire truss mechanism 30. The two ends of the vertical axis assembly 40 are respectively movably connected to two cross beams of the horizontal axis bracket 32, so that the horizontal axis assembly 31 can drive the vertical axis assembly 40 to move horizontally; the vertical axis assembly 50 is movably connected to the vertical axis assembly 40, so that the vertical axis assembly 40 can drive the vertical axis assembly 50 to move vertically; the grasping mechanism 20 is fixedly connected to the driving end of the vertical axis assembly 50, so that the vertical axis assembly 50 can drive the grasping mechanism 20 to move vertically.

[0051] As Figure 5 shown, preferably, the horizontal axis assembly 31 is further provided with a horizontal axis guide rail 33, a horizontal axis roller 34, a horizontal axis motor 35, a first inclined rack 36 and a first inclined gear 37. The first inclined rack 36 and the horizontal axis guide rail 33 are respectively fixedly connected to the top of the horizontal axis bracket 32. The horizontal axis motor 35 and the horizontal axis roller 34 are respectively fixedly connected to the two ends of the vertical axis assembly 40. The horizontal axis roller 34 and the horizontal axis guide rail 33 cooperate with each other to form a rolling connection; the first inclined gear 37 is fixedly connected to the output shaft of the horizontal axis motor 35 and meshes with the first inclined rack 36 to form an inclined tooth transmission, so that the horizontal axis motor 35 operates to drive the vertical axis assembly 40 to move horizontally along the horizontal axis guide rail 33.

[0052] Specifically, to support both ends of the longitudinal axis assembly 40, the transverse axis support 32 can be provided with two crossbeams and multiple pillars. One end of each pillar is fixed to the floor of the factory building, and the other end is fixed to the crossbeam, thereby supporting the crossbeam. It is understood that in order to synchronously drive both ends of the longitudinal axis assembly 40, two sets of transverse axis assemblies 31 are required, with the two sets of transverse axis assemblies 31 being mounted on the two crossbeams respectively. At the same time, the transverse axis motor 35 is preferably configured as a synchronous motor or servo motor, so that the motors of the two sets of transverse axis assemblies 31 can move synchronously and drive the longitudinal axis assembly 40 simultaneously.

[0053] like Figure 5 and Figure 6 As shown, preferably, the longitudinal axis assembly 40 is provided with a longitudinal axis bracket 41, a longitudinal axis guide rail 42, a longitudinal axis slider 43, a longitudinal axis motor 44, a second bevel rack 45 and a second bevel gear 46. The longitudinal axis bracket 41 is used to support the vertical axis assembly 50, and its two ends are movably connected to the two crossbeams of the horizontal axis bracket 32; the second bevel rack 45 and the longitudinal axis guide rail 42 are respectively fixed to the top of the longitudinal axis bracket 41, and the longitudinal axis motor 44 and the longitudinal axis slider 43 are respectively fixed to the vertical axis assembly 50, and the longitudinal axis slider 43 and the longitudinal axis guide rail 42 cooperate with each other to form a linear sliding connection; the second bevel gear 46 is fixed to the output shaft of the longitudinal axis motor 44, and meshes with the second bevel rack 45 to form a bevel gear transmission, so that the longitudinal axis motor 44 is operated to drive the vertical axis assembly 50 to move longitudinally along the longitudinal axis guide rail 42.

[0054] Specifically, in order to enhance the heavy-load capacity of the longitudinal axis assembly 40, it is preferred to provide two sets of longitudinal axis brackets 41, and to respectively provide corresponding longitudinal axis guide rails 42, longitudinal axis sliders 43, longitudinal axis motors 44, second bevel racks 45, and second bevel gears 46 on the two sets of longitudinal axis brackets 41. A longitudinal movement space is formed between the two sets of longitudinal axis brackets 41, so that the vertical axis assembly 50 can be installed in this space, thereby forming a structure in which both sides of the vertical axis assembly 50 are respectively overlapped with the two sets of longitudinal axis brackets 41, thereby enhancing the heavy-load capacity of the longitudinal axis assembly 40. Similarly, the longitudinal axis motor 44 is preferably configured as a synchronous motor or a servo motor, so that the motors of the two sets of longitudinal axis assemblies 40 can move synchronously and drive the vertical axis assembly 50 at the same time.

[0055] like Figure 6 and Figure 7As shown, preferably, the vertical axis assembly 50 is provided with a vertical axis bracket 51, a vertical axis guide rail 52, a vertical axis slider 53, a vertical axis motor 54, a third bevel rack 55 and a third bevel gear 56, and the grabbing mechanism 20 is provided with a grabbing rod 21, the grabbing rod 21 is connected to the vertical axis bracket 51, and the two sides of the vertical axis bracket 51 are respectively connected to the longitudinal axis assembly 40; the third bevel rack 55 and the vertical axis guide rail 52 are respectively fixed to the grabbing rod 21, and the vertical axis motor 54 and the vertical axis slider 53 are respectively fixed to the vertical axis bracket 51, and the vertical axis slider 53 and the vertical axis guide rail 52 cooperate with each other to form a linear sliding connection; the third bevel gear 56 is fixed to the output shaft of the vertical axis motor 54, and meshes with the third bevel rack 55 to form a bevel gear transmission, so that the vertical axis motor 54 is operated to drive the grabbing rod 21 to move vertically along the vertical axis guide rail 52.

[0056] Specifically, the two sides of the vertical axis bracket 51 correspond to the side surfaces of the two sets of longitudinal axis brackets 41. Preferably, corresponding vertical axis guide rails 52 and vertical axis sliders 53 are also provided on each side. This allows the vertical axis bracket 51 to provide support for the grab bar 21 from both sides simultaneously, thereby making the sliding connection more stable and preventing tilting or offset. Furthermore, to enhance the stability of the connection between the vertical axis bracket 51 and the grab bar 21, two sets of vertical axis guide rails 52 and vertical axis sliders 53 can also be provided on the same side.

[0057] like Figure 6 As shown, preferably, the vertical axis assembly 50 is further provided with a worm reducer 57 , which is fixed to the vertical axis bracket 51 , and its input end is transmission-connected to the output shaft of the vertical axis motor 54 , and its output end is fixed to a third helical gear 56 .

[0058] Specifically, since the vertical axis assembly 50 needs to drive the grabbing rod 21 to move vertically, it is necessary to ensure that after the grabbing mechanism 20 grabs the material tank 70, no accidents will occur during the movement. Therefore, the worm reducer 57 preferably adopts a transmission mechanical device with a self-locking function, so that it can perform a self-locking braking function in the event of a power outage, etc., to prevent the material tank 70 and the grabbing rod 21 from falling.

[0059] like Figure 7 As shown, preferably, the grabbing mechanism 20 is further provided with a grabbing hook seat 22, a locking pin 24 and a locking cylinder 25. The grabbing hook seat 22 is fixedly connected to the lower part of the grabbing rod 21 and is provided with a hook seat pin hole 23. The locking pin 24 is passed through the hook seat pin hole 23 and can be moved in a direction perpendicular to the axial direction of the locking pin 24. The locking cylinder 25 is fixedly connected to the grabbing hook seat 22, and its piston rod is transmission-connected to the locking pin 24, thereby driving the locking pin 24 so that it can lock or unlock the grabbing hook 71 of the material tank 70.

[0060] Specifically, a T-shaped transmission member 26 can also be provided, with one end of the T-shaped transmission member 26 being fixed to the piston rod of the locking cylinder 25 and the other end being sleeved on the locking pin 24, so as to better drive the locking pin 24 and enable the locking pin 24 to move within the hook seat pin hole 23. Similarly, the locking cylinder 25 can preferably also be a magnetic cylinder with a magnetic induction switch or a magnetic induction sensor, so as to detect the movement position of the piston rod and feed it back to the control module, so that it can calculate whether the locking pin 24 is pushed into the grab hook 71 of the material tank 70 through the movement position of the piston rod and whether the grab hook 71 is locked. In order to improve safety, preferably, the locking cylinder 25 can be controlled to retract at a high level and push out at a low level, so as to ensure that there is no risk of the material tank 70 falling when there is no electricity or gas.

[0061] In addition, after the grabbing rod 21 moves upward to grab the material tank 70, that is, after the grabbing hook 71 of the material tank 70 has locked the locking pin 24, the locking cylinder 25 can no longer push the locking pin 24 to unlock it. The material tank 70 must be moved into place, the grabbing rod 21 moves downward, and the material tank 70 is placed on the corresponding loading and unloading platform 10 or discharge mechanism 60. After the grabbing hook 71 releases the lock on the locking pin 24, the locking cylinder 25 can pull the locking pin 24 back again to perform the corresponding unlocking operation.

[0062] like Figure 8 As shown, preferably, the discharge mechanism 60 is provided with a discharge bracket 61, a lifting electric cylinder 62, a carrying platform 65, a linear bearing 63 and a cylindrical shaft 64. The discharge bracket 61 is used to support the entire discharge mechanism 60. The lifting electric cylinder 62 and the linear bearing 63 are respectively fixed to the discharge bracket 61. The cylindrical shaft 64 and the linear bearing 63 cooperate with each other to form a linear motion system. The carrying platform 65 is fixed to one end of the cylindrical shaft 64 and forms a transmission connection with the driving shaft of the lifting electric cylinder 62, so that the operation of the lifting electric cylinder 62 can drive the carrying platform 65 to move up and down.

[0063] Specifically, since the carrying platform 65 needs to support the material tank 70, the linear bearing 63 is preferably a flange-type linear bearing 63 that can bear large loads. Two sets of linear bearings 63 and cylindrical shafts 64 are simultaneously provided at both ends of the unloading bracket 61, forming a total of four linear motion systems, thereby providing stable support for the carrying platform 65. The lifting cylinder 62 is preferably a screw lift cylinder, ball screw cylinder, or other type with high load capacity and good self-locking performance to drive the carrying platform 65.

[0064] The carrying platform 65 is further provided with guiding and positioning columns 66. When the grasping mechanism 20 places the material tank 70 into the discharging mechanism 60, the guiding and positioning columns 66 can be sleeved through the guiding and positioning holes 72 at the bottom of the material tank 70, so as to perform guiding and positioning operations on the material tank 70 and place it at a preset position.

[0065] In addition, a weighing feedback device (not shown in the figure) can be arranged on the carrying platform 65, so as to weigh the material tank 70 and feedback the weighed weight to the control module, enabling the control module to select the next operation action according to the weight of the material tank 70.

[0066] Secondly, since a corresponding discharging valve (not shown in the figure) is also arranged at the bottom of the material tank 70, an open-valve mechanism (not shown in the figure) can be arranged at the position corresponding to the discharging valve on the carrying platform 65. After the material tank 70 is placed on the carrying platform 65, the lifting electric cylinder 62 drives the carrying platform 65 to move downward, so that the discharging valve below the material tank 70 is docked with the feeding port of the mixer 80. Subsequently, the open-valve mechanism can be used to open the discharging valve, enabling the materials inside the material tank 70 to flow into the mixer 80 for corresponding mixing operations.

[0067] During operation, a worker can use tools such as a forklift to lift the material tank 70 to the loading and unloading platform 10, and then push it to a specified preset position. After completion, the worker inputs the parameters of the material tank 70 on the operation screen of the control module and sends an instruction to the truss mechanism 30. The truss mechanism 30 controls the grasping mechanism 20 to move to a corresponding position, grabs the material tank 70 directly above the corresponding working station of the mixer 80, and sends an instruction to the mixer 80. The mixer 80 opens the docking material port for docking.

[0068] The discharging mechanism 60 is also required for assistance. The vertical shaft assembly 50 of the truss mechanism 30 controls the grasping mechanism 20 to descend a certain height, places the material tank 70 at the preset position of the discharging mechanism 60, the grasping mechanism 20 releases the locking pin shaft 24, the vertical shaft assembly 50 controls the grasping mechanism 20 to rise a certain height, and then the truss mechanism 30 controls the vertical movement assembly and the grasping mechanism 20 to return to the original position or an empty position synchronously, waiting for the next operation instruction.

[0069] Subsequently, the discharging mechanism 60 can control the carrying platform 65 to move downward a certain distance, dock the discharging port of the material tank 70 with the feeding port of the mixer 80, and then the control module can control the corresponding valve to open, so that the materials loaded inside the material tank 70 flow into the mixer 80, completing the feeding operation of a large amount of materials at one time and improving the operation efficiency of the entire mixer 80 station.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
