Description

Technical Field

[0001] The present invention belongs to the technical field of machining equipment, and particularly relates to a high-speed servo feeder. Background Art

[0002] A punching press is a key equipment widely used in the manufacturing industry and plays an irreplaceable role in the field of metal sheet processing. The main function of the punching press is to perform a series of process operations such as punching, cutting, and forming on metal sheets, providing a convenient and efficient solution for various manufacturing processes. Currently, all punching presses on the market are equipped with fully automatic feeders, which enables workers to avoid manual feeding. Such a feeder not only reduces the labor cost but also greatly improves the efficiency. However, since the feeders currently on the market are basically composed of a machine base, a driving roller disposed on the machine base, several driven rollers, and a motor for driving the driving roller to rotate, the metal sheet is generally placed on the driving roller and the driven rollers. The motor works to drive the driving roller to rotate, and the rotation of the driving roller drives the metal sheet to move, so that the metal sheet moves along the driven rollers and is finally conveyed into the processing area. During this process, the movement of the metal sheet mainly depends on the rotation of the driving roller. In this way of single-power conveying the metal sheet, the feeding speed of the feeding device is relatively slow, resulting in a slow processing efficiency of the punching press. Moreover, if the feeding speed of such a feeding device is increased, the following problems will occur: when the feeding speed is too fast, the moving speed of the metal sheet increases, and thus its own inertia also increases. After the roller stops rotating, the metal sheet will continue to move a certain distance, resulting in a part of the sheet body exceeding the processing area of the punching press, so that the metal sheet cannot be utilized to the greatest extent and it is easy to cause waste of the metal sheet raw material. Summary of the Invention

[0015] The prominent and beneficial technical effects of the present invention compared with the prior art are:

[0016] The present invention belongs to the technical field of machining equipment, and particularly refers to a high-speed servo feeder, which includes a machine base. There are a feed inlet, a discharge outlet and a feeding channel on the machine base. The feeding channel is located between the feed inlet and the discharge outlet, and the feeding device in the feeding channel can convey the metal sheet from the feed inlet into the feeding channel and finally convey it from the discharge outlet to the processing area of the punching press. The feeding device is composed of a lower roller and an upper roller. The first driving device and the second driving device on the machine base are respectively used to control the rotation of the lower roller and the upper roller. The upper roller is located directly above the lower roller, and a gap for the material to pass through is formed between the lower roller and the upper roller. When a worker wants to convey the metal sheet normally, it is necessary to first place one end of the metal sheet into the gap between the lower roller and the upper roller. At this time, the first driving device and the second driving device respectively control the lower roller and the upper roller to rotate synchronously, so as to drive the metal sheet to move towards the feeding channel under the cooperation of the lower roller and the upper roller. Compared with the single-power method of conveying metal sheets on the market, the double-power conveying method of the present invention, which controls the lower roller and the upper roller to rotate synchronously through the first driving device and the second driving device, enables the metal sheet to be conveyed faster. At this time, the worker can adjust the processing speed of the punching press. The punching press is a common device on the market, and its processing speed can be adjusted according to the actual processing situation, thereby greatly increasing the processing efficiency of the metal sheet. One end of the swing lower pressing plate in the feeding channel is rotatably connected to the machine base, and the other end of the swing lower pressing plate is located above the upper roller. The swing lower pressing plate is connected to the upper roller through a linkage seat, and the driving mechanism on the machine base can be used to control the swing lower pressing plate to swing up and down reciprocally around one end of the swing lower pressing plate. After the driving mechanism works, it can push the other end of the swing lower pressing plate to move downward. At this time, the linkage seat on the swing lower pressing plate will move downward synchronously, and after the linkage seat moves downward, it will drive the upper roller to move downward synchronously, so as to reduce the gap between the upper roller and the lower roller, and the upper roller presses the metal sheet in the gap tightly. At this time, the friction force between the metal sheet and the upper roller and the lower roller increases greatly. Therefore, when the metal sheet needs to stop during the rapid movement to process the unprocessed sheet conveyed into the processing area of the punching press, after the first driving device and the second driving device stop working, the lower roller and the upper roller will stop rotating. Due to the pressure of the upper roller, the friction force between the metal sheet and the upper roller and the lower roller increases, so that the metal sheet will not continue to move forward a certain distance, thus avoiding the situation that the unprocessed metal sheet exceeds the processing area of the punching press. At present, positioning pins are provided on the punching presses on the market, and the metal sheet can be driven to move according to the positioning pins, so as to eliminate the deviation generated during the movement of the metal sheet. When it is necessary to finely adjust the position of the metal sheet with the positioning pins, at this time, the driving mechanism starts to work, so as to drive the other end of the swing lower pressing plate to move upward. At this time, the linkage seat on the swing lower pressing plate will move upward synchronously, and after the linkage seat moves upward, it will drive the upper roller to move upward synchronously.Thus, the upper roller is moved away from and separated from the metal sheet, so that when the positioning pin fine-tunes the position of the metal sheet, the situation where the fine-tuning work cannot be carried out because the metal sheet is clamped by the upper roller will not occur. After the fine-tuning work is completed, at this time, the driving mechanism starts to work again to drive the other end of the swing lower pressing plate to move downward, and finally the upper roller will clamp the metal sheet again. The feeder of the present invention can not only achieve rapid feeding, but also when the first driving device and the second driving device stop working, the metal sheet can stop moving immediately, enabling the metal sheet to be utilized to the greatest extent and preventing waste of the metal sheet raw material.

[0056] The present invention will be further described below in conjunction with specific embodiments:

[0057] The present invention belongs to the technical field of machining equipment, and particularly refers to a high-speed servo feeder, which includes a machine base 1. There are a feed inlet 2, a discharge outlet 3 and a feeding channel 4 on the machine base 1. The feeding channel 4 is located between the feed inlet 2 and the discharge outlet 3. And the feeding device in the feeding channel 4 can convey the metal sheet from the feed inlet 2 into the feeding channel 4 and finally convey it from the discharge outlet 3 to the processing area of the punching press. The feeding device is composed of a lower roller 5 and an upper roller 6. The first driving device 7 and the second driving device 8 on the machine base 1 are respectively used to control the rotation of the lower roller 5 and the upper roller 6. The upper roller 6 is located directly above the lower roller 5, and a gap 9 through which the material can pass is formed between the lower roller 5 and the upper roller 6. When a worker wants to convey the metal sheet normally, it is necessary to first place one end of the metal sheet into the gap 9 between the lower roller 5 and the upper roller 6. At this time, the first driving device 7 and the second driving device 8 respectively control the lower roller 5 and the upper roller 6 to rotate synchronously, so as to drive the metal sheet to move towards the feeding channel 4 under the cooperation of the lower roller 5 and the upper roller 6. Compared with the single-power method of conveying metal sheets on the market, the double-power conveying method of the present invention, which controls the lower roller 5 and the upper roller 6 to rotate synchronously through the first driving device 7 and the second driving device 8, makes the conveying speed of the metal sheet faster. At this time, the worker can adjust the processing speed of the punching press. The punching press is a common device on the market, and its processing speed can be adjusted according to the actual processing situation, so as to greatly increase the processing efficiency of the metal sheet. One end of the swinging lower pressing plate 10 in the feeding channel 4 is rotatably connected to the machine base 1, and the other end of the swinging lower pressing plate 10 is located above the upper roller 6. The swinging lower pressing plate 10 is connected to the upper roller 6 through a linkage seat 11. And the driving mechanism on the machine base 1 can be used to control the swinging lower pressing plate 10 to swing up and down reciprocally around one end of the swinging lower pressing plate 10. After the driving mechanism works, it can push the other end of the swinging lower pressing plate 10 to move downward. At this time, the linkage seat 11 on the swinging lower pressing plate 10 will move downward synchronously. After the linkage seat 11 moves downward, it will drive the upper roller 6 to move downward synchronously, so as to reduce the gap 9 between the upper roller 6 and the lower roller 5, and the upper roller 6 presses the metal sheet in the gap 9 tightly. At this time, the friction force between the metal sheet and the upper roller 6 and the lower roller 5 increases greatly. So when the metal sheet needs to stop during the rapid movement to process the unprocessed sheet body conveyed into the processing area of the punching press, at this time, after the first driving device 7 and the second driving device 8 stop working, the lower roller 5 and the upper roller 6 will stop rotating. Due to the pressure of the upper roller 6, the friction force between the metal sheet and the upper roller 6 and the lower roller 5 increases, so that the metal sheet will not continue to move forward for a certain distance, thus avoiding the situation that the unprocessed metal sheet body exceeds the processing area of the punching press. At present, positioning pins are available on punching presses on the market, and they can drive the metal sheet to move according to the positioning pins, so as to eliminate the deviation generated during the movement of the metal sheet. And when it is necessary to use the positioning pins to finely adjust the position of the metal sheet,At this time, the driving mechanism starts to work, driving the other end of the swinging lower pressing plate 10 to move upward. At this time, the linkage seat 11 on the swinging lower pressing plate 10 will move upward synchronously. After the linkage seat 11 moves upward, it will drive the upper roller 6 to move upward synchronously, so that the upper roller 6 moves away from the metal plate and separates from the metal plate. Thus, when the positioning pin fine-tunes the position of the metal plate, the situation where the fine-tuning work cannot be carried out because the metal plate is clamped by the upper roller 6 will not occur. When the fine-tuning work is completed, at this time, the driving mechanism starts to work again to drive the other end of the swinging lower pressing plate 10 to move downward. Finally, the upper roller 6 will clamp the metal plate again. The feeder of the present invention can not only achieve rapid feeding, but also when the first driving device 7 and the second driving device 8 stop working, the metal plate can stop moving immediately, enabling the metal plate to be utilized to the greatest extent and preventing waste of the metal plate raw material.

[0058] Preferably, the driving mechanism includes a third driving device arranged on the machine base 1 and a yaw and lift seat 15 connected to the swinging lower pressing plate 10. The third driving device includes a third servo motor 13 and a third driving shaft 14. The third driving shaft 14 passes through the machine base 1 and enters the feeding channel 4. The yaw and lift seat 15 is provided with a driving space 16. A cam 17 is arranged on the third driving shaft 14. The cam 17 is located in the driving space 16 and abuts against the yaw and lift seat 15. When the positioning pin is needed to fine-tune the position of the metal plate, at this time, the third servo motor 13 works, driving the third servo motor 13 to drive the third driving shaft 14 to rotate. Since the cam 17 on the third driving shaft 14 is located in the driving space 16 of the yaw and lift seat 15, when the third driving shaft 14 rotates, it will drive the cam 17 to rotate synchronously. The cam 17 is a common component on the market. When the cam 17 rotates, the protruding part of the cam 17 will push the yaw and lift seat 15 upward. And since one end of the swinging lower pressing plate 10 is rotatably connected to the machine base 1, at this time, the yaw and lift seat 15 will drive the other end of the swinging lower pressing plate 10 to move upward, finally causing the upper roller 6 to move upward and away from the metal plate. At this time, the third servo motor 13 stops working, enabling the positioning pin on the punching machine to smoothly fine-tune the position of the metal plate. The third servo motor 13 is a common servo motor on the market, which can accurately control the rotation angle of the third driving shaft 14. And when the upper roller 6 moves upward, at this time, the gap 9 between the lower roller 5 and the upper roller 6 becomes larger, which is also convenient for workers to put one end of the metal plate into the gap 9 between the lower roller 5 and the upper roller 6. When the positioning pin finishes fine-tuning the position of the metal plate, at this time, the third servo motor 13 starts to work again, driving the third driving shaft 14 and the cam 17 to rotate synchronously, so that the protruding part of the cam 17 is disengaged from the abutting state with the yaw and lift seat 15. At this time, the swinging lower pressing plate 10, the upper roller 6 and the yaw and lift seat 15 will reset downward due to their own gravity, causing the upper roller 6 to clamp the metal plate again.

[0059] Preferably, an installation groove 18 is formed in the yaw and lift seat 15. The installation groove 18 communicates with the driving space 16. A rotating bearing 19 and an installation shaft 20 are arranged in the installation groove 18. The installation shaft 20 is fixedly arranged in the installation groove 18. The rotating bearing 19 is sleeved on the installation shaft 20. The bottom end of the rotating bearing 19 exposes into the driving space 16 and abuts against the cam 17. The arrangement of the installation groove 18 enables the rotating bearing 19 and the installation shaft 20 to be smoothly installed on the yaw and lift seat 15. The installation groove 18 communicates with the driving space 16, enabling the bottom end of the rotating bearing 19 to smoothly expose into the driving space 16 and abut against the cam 17. The arrangement of the rotating bearing 19 enables the rotating bearing 19 to rotate with the cam 17 when the cam 17 rotates, thereby reducing the frictional force that needs to be overcome when the cam 17 rotates, reducing the wear caused when the cam 17 rotates, and increasing the service life of the cam 17.

[0060] Preferably, a first bearing seat 21 and a second bearing seat 22 are arranged in the feeding channel 4. The first bearing seat 21 and the second bearing seat 22 are connected to the machine base 1. The yaw and lift seat 15 is located between the first bearing seat 21 and the second bearing seat 22. Bearing grooves 23 are formed in both the first bearing seat 21 and the second bearing seat 22. A rotating hole 24 is formed at the bottom end of the bearing groove 23. The third driving shaft 14 sequentially passes through the rotating hole 24 in the first bearing seat 21, the driving space 16, and the rotating hole 24 in the second bearing seat 22. Movable bearings 25 are arranged in the bearing grooves 23. The movable bearings 25 are sleeved on the third driving shaft 14. Bearing gland plates 26 are fixedly arranged on both the first bearing seat 21 and the second bearing seat 22. The bearing gland plates 26 abut against the movable bearings 25 in the bearing grooves 23. Since the third driving shaft 14 sequentially passes through the rotating hole 24 in the first bearing seat 21, the driving space 16 on the yaw and lift seat 15, and the rotating hole 24 in the second bearing seat 22, and due to the arrangement of the first bearing seat 21 and the second bearing seat 22, the angle of the third driving shaft 14 will not deviate when it rotates. Movable bearings 25 are arranged in the bearing grooves 23 of both the first bearing seat 21 and the second bearing seat 22, and the movable bearings 25 are sleeved on the third driving shaft 14, thereby enabling the third driving shaft 14 to rotate more smoothly, reducing the friction between the third driving shaft 14 and the first bearing seat 21 and the second bearing seat 22, increasing the service life of the third driving shaft 14, and the arrangement of the bearing gland plates 26 on the first bearing seat 21 and the second bearing seat 22 can press the movable bearings 25 in the bearing grooves 23, thereby restricting the movable bearings 25 from disengaging from the bearing grooves 23.

[0061] Preferably, rotating ends 27 and connecting ends 28 are respectively provided at two ends of the lower roller 5. Left bearing seats 29 and right bearing seats 30 are respectively arranged in the feeding channel 4. Both the left bearing seat 29 and the right bearing seat 30 are connected to the machine base 1. The rotating end 27 is rotatably connected to the left bearing seat 29. The first driving device 7 is a first servo motor. A first motor shaft 31 is provided on the first servo motor. A coupling 32 is provided on the first motor shaft 31. The connecting end 28 passes through the right bearing seat 30 and the machine base 1 and is fixedly connected to the coupling 32. Both the left bearing seat 29 and the right bearing seat 30 are common bearing vertical fixing seats on the market. The rotating end 27 at one end of the lower roller 5 is rotatably connected to the left bearing seat 29. The connecting end 28 at the other end of the lower roller 5 passes through the right bearing seat 30 and the machine base 1 and is fixedly connected to the coupling 32 on the first motor shaft 31, so that the lower roller 5 is mounted in the feeding channel 4. The first servo motor is a common servo motor on the market. When the servo motor starts to work, the first motor shaft 31 will rotate at this time, thus driving the coupling 32 to continue rotating. The coupling 32 drives the connecting end 28 of the lower roller 5 to rotate, and finally the lower roller 5 rotates. The setting of the servo motor enables workers to accurately control the number of rotation turns of the lower roller 5, so as to accurately control the moving distance of the metal sheet, ensure that the moving distance of the metal sheet each time is the same, and achieve high-precision feeding.

[0062] Preferably, the linkage seat 11 includes a left linkage seat 33 and a right linkage seat 34.

When the metal sheet passes through the feeding channel 4, the metal sheet will contact the length measuring wheel 58. When the metal sheet moves, it will drive the length measuring wheel 58 to rotate. The number of rotations of the length measuring wheel 58 can be used to calculate the moving distance of the metal sheet, and the moving data of the metal sheet is transmitted to the length measuring motor 56. Finally, when the moving distance of the metal sheet reaches the preset value, the first driving device 7 and the second driving device 8 will stop working, thus accurately controlling the moving distance of the metal sheet.

The connecting shaft 59 is located in the activity hole 61 of the fulcrum bearing seat 60, and the fulcrum bearings 62 in the activity hole 61 are sleeved on the connecting shaft 59, so that when one end of the swinging lower pressing plate 10 rotates relative to the connecting shaft 59, it is smoother. Positioning bearings 65 are provided on both the left positioning seat 63 and the right positioning seat 64 in the feeding channel 4. The positioning bearing 65 on the left positioning seat 63 and the positioning bearing 65 on the right positioning seat 64 respectively abut against the left and right sides of the swinging lower pressing plate 10, so that the swinging lower pressing plate 10 can be effectively connected to move left and right in the feeding channel 4.

[0066] Preferably, an auxiliary clamping device 69 is provided on the machine base 1. The number of the auxiliary clamping devices 69 is two.

The rubber air spring 66 is fixedly connected to the machine base 1 through the upper pressing plate 68 and fixedly connected to the swinging lower pressing plate 10 through the lower fixing block 67. When the third servo motor 13 works, after a series of transmissions, the protruding part of the cam 17 abuts against the yaw lifting seat 15. At this time, while the yaw lifting seat 15 moves upward, it drives one end of the swinging lower pressing plate 10 to move upward synchronously, so that the rubber air spring 66 is in a compressed state. At this time, the upper roller 6 will be separated from the metal sheet. When the third servo motor 13 works again, the protruding part of the cam 17 is disengaged from the yaw lifting seat 15. At this time, the compressed rubber air spring 66 will push the swinging lower pressing plate 10 to reset, and finally the yaw lifting seat 15 and the upper roller 6 are reset, thus ensuring that the swinging lower pressing plate 10 and the upper roller 6 can be reset, enabling the upper roller 6 to clamp the metal sheet and enabling the feeder to be used normally. The number of the auxiliary clamping devices 69 is two. Therefore, under the elastic action of the two rubber air springs 66, without external force, the upper roller 6 will not move upward, thus ensuring that the upper roller 6 can always clamp the metal sheet.
