Description

Technical Field

[0001] This application relates to the field of shaft core processing equipment, and in particular to a shaft core feeding machine and its working method. Background Technology

[0002] As a core component of mechanical transmission and support systems, shafts play a vital role in the automotive industry, rail transportation, industrial machinery, and electronic equipment. They ensure stable positioning and precise transmission of rotating parts. With diverse structures and strong adaptability, they can be designed in different shapes, sizes, and precision levels to meet various application scenarios, from microelectronic devices to heavy industrial machinery.

[0003] In the actual processing, the shaft core needs to be provided with mounting positions that are compatible with the connected parts, such as threaded sections, grooves, and anti-slip textures, according to the design requirements. After the shaft core is processed and shaped by the processing equipment, it needs to be stored and transported in a unified manner so that the processed shaft core can be used in subsequent workpiece production processes.

[0004] For example, if a fan shaft needs to be processed, during the actual assembly process, operators need to inspect and arrange numerous shafts so that they are aligned in the same direction along the conveyor. This allows the controller to take the shafts from the next processing equipment. With the development and advancement of intelligent manufacturing technology and equipment, the production speed has been significantly improved. However, for small-sized shafts, if operators cannot change the direction of the shafts in time, it will cause chaos in the next processing steps and inconsistent material feeding rates, which is detrimental to improving the processing efficiency of the next processing equipment in installing the shafts onto the product. Summary of the Invention

[0005] The purpose of this invention is to facilitate the orderly delivery of small-sized shaft cores after production to the next-level processing equipment, so that the arrangement direction of the shaft cores arriving at the next-level processing equipment does not need to be adjusted a second time. This application provides a shaft core feeding machine and its working method.

[0006] To achieve the above objectives, the present application provides a shaft core feeding machine and its working method, which adopts the following technical solution: In a first aspect, this application discloses a shaft core feeding machine, including a frame and a hopper disposed on the frame. The hopper has a discharge port. A discharge tray is rotatably supported on the frame near the discharge port. The outer wall of the discharge tray has a plurality of receiving grooves adapted to the external contour of the shaft core along the circumferential direction. A detection mechanism and a feeding mechanism are sequentially disposed on the frame near the discharge tray. The detection mechanism includes a first detector and a rejection component. The rejection component includes a first air nozzle. The detection end of the first detector faces the discharge tray, and the first air nozzle faces the receiving groove. The feeding mechanism includes a second air nozzle and a feeding slider. The feeding slider slides in cooperation with the frame. A support groove is disposed on the feeding slider. The second air nozzle is disposed on the frame near the downstream production equipment. The second air nozzle is used to feed the shaft core located in the support groove to the downstream production equipment.

[0007] Preferably, the rejection assembly further includes an auxiliary baffle, which includes a first drive cylinder and a baffle plate. The baffle plate is fixedly connected to the piston rod of the drive cylinder. The baffle plate has a through-hole along the thickness direction. When the first air nozzle is not activated, the through-hole is misaligned with the spatial position of the receiving groove facing the first detector.

[0008] Preferably, a buffer groove is provided on the frame near the first detector. The width of the buffer groove and the diameter of the shaft core are in a clearance fit. When the feeding slider is not in motion, the support groove faces the buffer groove.

[0009] Preferably, a fixing block is provided on the hopper, and a limiting groove is formed between the fixing block and the hopper, and a baffle is provided in the limiting groove.

[0010] Preferably, the hopper and the horizontal plane of the frame are provided with an included angle α, where 65°≤α≤85°.

[0011] Preferably, it also includes an auxiliary positioning component, which includes an adjusting seat and a second detector. The adjusting seat is coaxially fixed with the feeding tray, and the adjusting seat has the same number of detection ports as the receiving slots. The second detector is mounted on the frame and faces the adjusting seat.

[0012] Preferably, a third detector is provided on the frame near the buffer tank, with the detection end of the third detector facing the buffer tank.

[0013] Preferably, the feeding tray has a connecting hole along the axial direction, and the diameter of the connecting hole and the diameter of the adjusting seat are in a transition fit. The feeding tray has a fixing hole extending through the side wall to the axial direction.

[0014] Preferably, a feeding pipe is provided on the frame near the second air nozzle, one end of the feeding pipe is connected to the downstream production equipment, and the other end of the feeding pipe faces the feeding slider.

[0015] Secondly, this application discloses a working method for a shaft core feeding machine, applied to a shaft core feeding machine as described in the first aspect, comprising: S1. Place the completed shaft core into the hopper. As the feeding tray rotates along the frame, the shaft cores in the hopper fall into the receiving slot in an orderly manner, so that the shaft cores in the receiving slot follow the feeding tray along the frame. S2. During the movement of the shaft core on the feeding tray, when the shaft core moves to the first detector, the current shaft core arrangement direction is detected by the first detector. S3. When the first detector detects that the current shaft core arrangement direction is inconsistent with the set direction, the first air nozzle starts to work and removes the current shaft core along the receiving groove; when the first detector detects that the current shaft core arrangement direction is consistent with the set direction, the feeding tray carries the current shaft core and continues to move along the frame. S4. When the current material tray carries the current shaft core to the buffer material tank, the current shaft core falls into the buffer material tank by its own gravity and then falls into the support groove along the buffer material tank. S5. When the next-level production equipment needs to use the shaft core, the feeding slider carries the shaft core located in the support groove and moves it toward the second air nozzle. S6. When the shaft core located in the support groove moves to the second air nozzle, the second air nozzle starts to work, sending the shaft core located in the support groove to the next production equipment.

[0016] Compared with the prior art, the present invention provides a shaft core feeding machine and its working method, which has the following beneficial effects: 1. The shaft cores are uniformly accommodated through the hopper. After the shaft cores are placed in the hopper, those near the receiving slot will fall into the receiving slot. The receiving slot limits the placement position of the shaft cores along the feeding tray. As the feeding tray rotates along the frame, the shaft cores located in the receiving slot will move synchronously along the frame with the feeding tray. When the shaft core in the receiving slot reaches the first detector, the first detector detects the placement direction of the shaft core. When it is detected that the current placement direction of the shaft core does not conform to the set direction, the first air nozzle removes the shaft core located in the receiving slot along the feeding tray. When the first detector... When the current shaft core discharge direction is detected to be consistent with the set direction, the feeding tray will carry the current shaft core and continue to move the feeding slider. When the shaft core reaches the feeding slider, the shaft core will fall into the support groove. Then the feeding slider will carry the shaft core in the support groove to the second air nozzle. After the shaft core reaches the second air nozzle, the shaft core in the support groove will be sent to the next production equipment through the second air nozzle. The operation is simple and plays a positive guiding role in the orderly delivery of small-sized shaft cores to the next processing equipment, so that the arrangement direction of the shaft cores arriving at the next processing equipment does not need to be adjusted again. 2. Through the cooperation of the first drive cylinder and the baffle plate, when the first air nozzle is not activated, the piston rod of the first drive cylinder drives the baffle plate to block the receiving groove, so as to prevent the shaft cores located in the receiving groove from being aligned with the preset alignment direction. Due to the shape characteristics of the shaft cores themselves, the shaft cores may fall off the receiving groove on their own. When the first detector detects that the shaft cores located in the current receiving groove are not aligned with the set direction, the piston rod of the first drive cylinder will drive the baffle plate to move along the frame, so that the receiving groove and the material passage hole are aligned, so as to quickly remove the shaft cores with incorrect placement along the frame. 3. The baffle is positioned within the hopper by limiting the groove formed between the fixed block and the hopper, and the shaft located in the hopper is sealed inside the hopper to prevent the shaft located in the hopper from being subjected to vibration or accidental shaking, which would cause the shaft located in the hopper to change its orientation within the hopper.

[0024] First, it should be noted that the controller described in this embodiment is a PLC (Programmable Logic Controller), which includes multiple functions such as logic control, timing control, analog control, and multi-machine communication. It also has a human-machine interface to facilitate the control and adjustment of the PLC. It is an existing controller, and its specific composition and working principle will not be described in detail here.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] Firstly, embodiments of this application disclose a shaft core feeding machine. (Refer to...) Figure 1 and Figure 2A shaft core feeding machine includes a frame 1 and a hopper 2 disposed on the frame 1. The hopper 2 has a discharge port 21. A discharge tray 11 is rotatably supported on the frame 1 near the discharge port 21. The outer wall of the discharge tray 11 has a plurality of receiving grooves 111 that are adapted to the outer contour of the shaft core along the circumferential direction. A detection mechanism 3 and a feeding mechanism 4 are sequentially disposed on the frame 1 near the discharge tray 11. The detection mechanism 3 includes a first detector 31 and a rejection component 32. In this embodiment, preferably, the first detector 31 is a diffuse reflection optical fiber, which determines whether the arrangement order of the shaft cores along the hopper 2 meets the set requirements. The rejection assembly 32 includes a first air nozzle 321, which is connected to an external compressed air source (e.g., an air compressor). The detection end of the first detector 31 faces the unloading tray 11, and the first air nozzle 321 faces the receiving groove 111. The feeding mechanism 4 includes a second air nozzle 41 and a feeding slider 42. The second air nozzle 41 is disposed on the frame 1 near the lower-level production equipment. The second air nozzle 41 is used to feed the shaft core located in the support groove 421 to the lower-level production equipment.

[0027] First, it should be noted that in this embodiment, the shaft core is made of metal material, and one end of the shaft core along the length direction has a textured pattern, while the other end of the shaft core along the length direction is in a smooth state. When the lower-level production equipment takes the shaft core located in the support groove 421, the smooth end of the shaft core needs to face the lower-level production equipment.

[0028] Specifically, refer to Figure 3 A servo motor 10 is installed on the hopper 2. The output shaft of the servo motor 10 moves through the hopper 2 and extends into the hopper 2. The feeding tray 11 is coaxially fixed with the output shaft of the servo motor 10. The purpose of driving the feeding tray 11 to rotate along the hopper 2 by the servo motor 10 is to control the rotation speed of the feeding tray 11 along the hopper 2.

[0029] Furthermore, the number of receiving slots 111 can be increased or decreased according to design requirements and the actual size of the feeding tray 11. Since the function of the receiving slots 111 and their cooperation with the feeding tray 11 are the same, the following will describe in detail the cooperation between one of the receiving slots 111 and the feeding tray 11.

[0030] The receiving groove 111 is formed by recessing the side wall of the feeding tray 11 towards the axis of the feeding tray 11. The shaft core is received by the receiving groove 111. During the process of the feeding tray 11 rotating along the frame 1 driven by the output shaft of the servo motor 10, the shaft core located in the hopper 2 falls into the receiving groove 111 in an orderly manner, so as to send the shaft core located in the hopper 2 to the detection mechanism 3 and the feeding mechanism 4.

[0031] Correspondingly, an angle α is set between the material bin 2 and the horizontal plane of the frame 1, 65°≤α≤85°. Because of the angle between the material bin 2 and the horizontal plane of the frame 1, the material bin 2 is tilted along the frame 1. When the shaft is placed in the material bin 2, the end of the shaft is tilted towards the horizontal plane of the frame 1, so that the shaft abuts against the inner wall of the material bin 2. This avoids the situation where the end of the shaft near the material bin 2 cannot abut against the material bin 2, thus preventing the shaft from falling accurately into the receiving groove 111. This helps to improve the smoothness of the shaft in the material bin 2 entering the receiving groove 111.

[0032] On the other hand, refer to Figure 4 A fixing block 22 is provided on the hopper 2, and a limiting groove 221 is formed between the fixing block 22 and the hopper 2. A baffle 6 is provided in the limiting groove 221. There are several fixing blocks 22, and the fixing blocks 22 are arranged at intervals along the outer wall of the hopper 2 by bolts. Since the shape of the fixing blocks 22 and the fixing method with the hopper 2 are the same, for ease of explanation, the following describes in detail the cooperation method between one fixing block 22 and the hopper 2.

[0033] The outer contour of the fixing block 22 is L-shaped, and the fixing block 22 is fixed to the hopper 2 by bolts, which improves the stability of the cooperation between the fixing block 22 and the hopper 2. Therefore, the limiting groove 221 formed between the fixing block 22 and the hopper 2 limits the placement position of the baffle 6 along the hopper 2 and seals the shaft core located in the hopper 2 inside the hopper 2, so as to prevent the shaft core located in the hopper 2 from being subjected to vibration or accidental shaking, which would cause the shaft core located in the hopper 2 to change its placement direction along the hopper 2. At the same time, in this embodiment, the baffle 6 can be made of acrylic material to make it transparent, so as to make it easy to observe the amount of shaft core in the hopper 2 at any time.

[0034] Reference Figure 3 The rejection component 32 also includes an auxiliary baffle 322, which includes a first drive cylinder 3221 and a baffle plate 3222. The baffle plate 3222 is fixedly connected to the piston rod of the drive cylinder. The baffle plate 3222 has a through hole 5 along the thickness direction. When the first nozzle 321 is not activated, the through hole 5 is misaligned with the receiving groove 111 of the first detector 31.

[0035] Specifically, the first drive cylinder 3221 is installed on the side of the hopper 2 away from the baffle 6. The piston rod of the first drive cylinder 3221 is connected to the connecting seat 9. The baffle 3222 is fixedly connected to the connecting seat 9. When the piston rod of the first drive cylinder 3221 moves, it will drive the connecting seat 9 to move synchronously along the frame 1 with the piston rod of the first drive cylinder 3221.

[0036] The purpose is that, through the cooperation of the first drive cylinder 3221 and the baffle plate 3222, when the first air nozzle 321 is not activated, the piston rod of the first drive cylinder 3221 drives the baffle plate 3222 to block the receiving groove 111, so as to prevent the shaft cores located in the receiving groove 111 from being aligned with the preset alignment direction. Due to the shape characteristics of the shaft cores themselves, the shaft cores may fall off along the receiving groove 111 on their own. When the first detector 31 detects that the shaft cores located in the current receiving groove 111 are not aligned with the set direction, the piston rod of the first drive cylinder 3221 will drive the baffle plate 3222 to move along the frame 1, so that the receiving groove 111 corresponds to the position of the material passage hole 5, so as to quickly remove the shaft cores with incorrect placement along the frame 1.

[0037] Reference Figure 4 and Figure 5 A buffer trough 12 is provided on the frame 1 near the first detector 31. The width of the buffer trough 12 and the diameter of the shaft core are in a clearance fit. When the feeding slider 42 is not in motion, the support groove 421 faces the buffer trough 12.

[0038] Specifically, the buffer hopper 12 is formed from one end near the feed tray 11 to the other end away from the feed tray 11. The height of the buffer hopper can be changed according to the actual height of the frame 1 or the number of shaft cores that need to be temporarily stored after testing, and the height of the buffer hopper 12 is not limited here.

[0039] Furthermore, a third detector 13 is installed on the frame 1 near the buffer hopper 12. The detection end of the third detector 13 faces the buffer hopper, and the third detector 13 can also be a diffuse reflection optical fiber. Its function is to detect whether there are still any completed shaft cores in the buffer hopper 12 through the third detector 13, and send the detection signal to the controller.

[0040] If the third detector 13 detects that the shaft core in the buffer trough 12 is in a fully loaded state, the controller will control the servo motor 10 to stop working, thereby stopping the unloading tray 11 from rotating along the frame 1, so as to stop the detection of the shaft core, so as to avoid the situation where the shaft core after being detected by the first detector 31 returns to the hopper 2 because the shaft core in the buffer trough 12 is in a fully loaded state.

[0041] Alternatively, when the third detector 13 detects that the amount of shaft cores in the buffer trough 12 is insufficient, the controller will control the servo motor 10 to start working, so that the unloading tray 11 will drive the shaft cores located in the hopper 2 to enter the receiving trough 111 in an orderly manner, and reach the first detector 31 for detection, thereby achieving the purpose of replenishing the shaft cores in the buffer trough 12 after the detection is completed.

[0042] Reference Figure 2 and Figure 5 It also includes an auxiliary positioning component 7, which includes an adjustment seat 71 and a second detector 72. The adjustment seat 71 is coaxially fixed with the feed tray 11. The adjustment seat 71 has the same number of detection ports 711 as the receiving slots 111. The second detector 72 is mounted on the frame 1 and faces the adjustment seat 71.

[0043] Specifically, a mounting base is installed on the frame 1 near the feeding tray 11, and the second detector 72 is installed on the mounting base. The second detector 72 can be a photoelectric sensor.

[0044] Furthermore, since the number of detection ports 711 is the same as the number of receiving slots 111, in this embodiment, the detection ports 711 located on the adjusting seat 71 correspond to the spatial positions of the receiving slots 111 located on the feeding tray 11, that is, any detection port 711 corresponds to one receiving slot 111.

[0045] In actual operation, the detection port 711 and the second detector 72 work together to provide a reference for the time and rotation angle of the servo motor 10.

[0046] For example, when the output shaft of the servo motor 10 drives the feeding tray 11 to rotate along the frame 1, if the detection end of the second detector 72 is not aligned with the detection port 711, it indicates that there is a positional deviation between the first detector 31 and the receiving groove 111. At this time, the servo motor 10 will continue to rotate along the frame 1 carrying the adjustment seat 71. When the detection port 711 and the detection end of the second detector 72 are aligned, the controller will control the servo motor 10 to stop working. At this time, the detection end of the first detector 31 is facing the receiving groove 111, so that the first detector 31 can detect the shaft core located in the receiving groove 111.

[0047] Meanwhile, as the working time of the servo motor 10 increases, the deviation of the circumferential rotation angle of the output shaft of the servo motor 10 from the initial state deviation of the servo motor 10 will be amplified. For example, in the initial state of the servo motor 10, the angle of the output shaft of the servo motor 10 in the initial stop state is 0°. However, as the working time of the servo motor 10 increases, when the servo motor 10 stops again, the angle between the output shaft of the servo motor 10 and the initial stop state is >0°. As a result, when the output shaft of the servo motor 10 stops rotating, the receiving groove 111 cannot be aligned with the detection end of the first detector 31.

[0048] Therefore, when the receiving slot 111 cannot be aligned with the detection end of the first detector 31, the initial position can be defined when the receiving slot 111 is aligned with the first detector 31. It is only necessary to rotate the adjusting seat 71 along the frame 1 so that the detection port 711 is aligned with the detection end of the second detector 72. The adjustment method is simple and does not require reprogramming the controller to reset the servo motor 10.

[0049] In addition, the feeding tray 11 has a connecting hole along the axial direction. The diameter of the connecting hole and the diameter of the adjusting seat 71 are in a transition fit. The feeding tray 11 has a fixing hole 1112 extending through the side wall to the axial direction. The adjusting seat 71 and the feeding tray 11 are fixed to each other with bolts through the fixing hole 1112. When it is necessary to adjust the angle relationship of the adjusting seat 71 along the feeding tray 11, simply loosen the bolts to release them from contact with the adjusting seat 71, and the adjusting seat 71 can be driven to rotate along the feeding tray 11 until the detection port 711 is directly opposite the second detector 72.

[0050] Furthermore, a feeding pipe 8 is provided on the frame 1 near the second air nozzle 41. One end of the feeding pipe 8 is connected to the next-level production equipment, and the other end of the feeding pipe 8 faces the feeding slider 42.

[0051] The feeding mechanism 4 also includes a second drive cylinder 43, which is mounted on the frame 1 near the buffer trough 12. The output shaft of the second drive cylinder 43 is fixedly connected to the feeding slider 42. By controlling the working state of the second drive cylinder 43, the feeding slider 42 is controlled to move along the frame 1 to the second air nozzle 41 or to the buffer trough 12.

[0052] When the feeding slider 42 carries the shaft core located in the buffer trough 12 to the second air nozzle 41, the second air nozzle 41 sends the shaft core located in the support groove 421 into the discharge pipe 8. At this time, the discharge pipe 8 is under negative pressure, thereby quickly sending the shaft core located in the discharge pipe 8 to the next processing equipment, resulting in high transfer efficiency.

[0053] Secondly, referring to Figure 6 This application discloses a working method for a shaft core feeding machine, comprising: S1. After the production is completed, the shaft core is placed into the material bin 2. When the feeding tray 11 rotates along the frame 1, the shaft core in the material bin 2 falls into the receiving groove 111 in an orderly manner, so that the shaft core in the receiving groove 111 moves along the frame 1 with the feeding tray 11. S2. During the movement of the shaft core carried by the feeding tray 11, when the shaft core moves to the first detector 31, the current shaft core arrangement direction is detected by the first detector 31. S3. When the first detector 31 detects that the current shaft core arrangement direction is inconsistent with the set direction, the first air nozzle 321 starts to work and removes the current shaft core along the receiving groove 111; when the first detector 31 detects that the current shaft core arrangement direction is consistent with the set direction, the feeding tray 11 carries the current shaft core and continues to move along the frame 1. S4. When the current shaft core is carried by the current material tray 11 to the buffer material tank 12, the current shaft core falls into the buffer material tank 12 by its own gravity and falls into the support groove 421 along the buffer material tank 12. S5. When the next production equipment needs to use the shaft core, the feeding slider 42 carries the shaft core located in the support groove 421 and moves it toward the second air nozzle 41. S6. When the shaft core located in the support groove 421 moves to the second air nozzle 41, the second air nozzle 41 starts to work and sends the shaft core located in the support groove 421 to the next production equipment.

[0054] This enables the continuous transport of small-sized shafts to lower-level processing equipment, and the orientation of the shafts delivered to the lower-level processing equipment meets design requirements.

[0055] The implementation principle of the shaft core feeding machine and its working method in this application embodiment is as follows: Shaft cores are uniformly accommodated through the hopper 2. After the shaft cores are placed in the hopper 2, the shaft cores near the receiving groove 111 will fall into the receiving groove 111. The receiving groove 111 limits the placement position of the shaft cores along the unloading tray 11. As the unloading tray 11 rotates along the frame 1, the shaft cores located in the receiving groove 111 will move synchronously along the frame 1 along with the unloading tray 11. When the shaft cores located in the receiving groove 111 reach the first detector 31, the first detector 31 detects the placement direction of the shaft cores. When it is detected that the current placement direction of the shaft cores does not conform to the set direction, the first air nozzle 321 removes the shaft cores located in the receiving groove 111. The shaft core is removed along the feeding tray 11; when the first detector 31 detects that the current shaft core discharge direction is consistent with the set direction, the feeding tray 11 will carry the current shaft core and continue to move to the feeding slider 42. When the shaft core reaches the feeding slider 42, the shaft core will fall into the support groove 421. Then the feeding slider 42 will carry the shaft core located in the support groove 421 to the second air nozzle 41. After the shaft core reaches the second air nozzle 41, the shaft core located in the support groove 421 will be sent to the next-level production equipment through the second air nozzle 41. The operation is simple and plays a positive guiding role in the orderly delivery of small-sized shaft cores to the next-level processing equipment, so that the arrangement direction of the shaft cores arriving at the next-level processing equipment does not need to be adjusted a second time.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
