Description

Technical Field

[0001] The present application relates to the technical field of bar feeding, and in particular to a feeder and a feeding method thereof. Background Art

[0002] During the bar processing process, a feeder is typically used to transport the bar. A typical feeder consists of a trough and a push rod. The bar is placed in the trough, and then the push rod pushes the bar toward the processing position within the trough for processing. To improve stability during bar processing, a sleeve is usually fixed to the end of the push rod facing the bar to hold the bar tail.

[0003] Generally, the diameter of the bars to be processed is between 20mm and 30mm. However, when processing some large-diameter bars with a diameter of 40mm-50mm, the remaining bars after processing are passed through the sleeve. Since the large-diameter bars are heavy, they are difficult to pull out. Manual auxiliary pulling is required before the next bar can be loaded, conveyed, and processed, thereby reducing the processing efficiency of the bars. This problem needs to be solved urgently. Summary of the Invention

[0004] In order to improve the processing efficiency of large-diameter bars, the present application provides a feeder and a feeding method thereof.

The pushing device includes a first driving member, a pushing rod and a sleeve, and the sleeve is fixedly arranged on the pushing rod toward one end of the bar for sleeve-catching the tail of the bar. The first driving member is arranged on the frame and is used for driving the pushing rod to move along the length direction of the feeding trough.

[0009] The pulling device includes a clamping mechanism and a separation mechanism. The clamping mechanism is arranged at a position of the frame close to the bar tail, and the separation mechanism is arranged at one end of the frame away from the bar processing position. When the bar processing operation is completed, the clamping mechanism clamps and fixes the bar tail, and the separation mechanism is used to drive the push rod to move quickly in a direction away from the bar tail.

[0010] By adopting the above technical scheme, the frame supports the loading device, the pushing device and the pulling device, the loading device conveys the bars one by one to the feeding trough, and then the first driving motor drives the chain to transmit by driving the sprocket, and the transmitted chain drives the pushing rod and the sleeve to move in the direction close to the bar through the driving plate, so that the sleeve covers the bar and pushes the bar to the processing position of the bar for processing operation. When the processing operation of the bar is completed, the clamping mechanism clamps the bar tail, and then the separation mechanism drives the pushing rod and the sleeve to move quickly in the direction away from the bar tail, thereby realizing the operation of pulling the bar tail out of the sleeve, so as to facilitate the next bar to be conveyed and processed. During the loading and conveying process of the bar, there is no need for manual assistance in pulling out the tail, and the degree of automation is high, which is conducive to improving the processing efficiency of large-diameter bars.

[0011] Preferably, the loading device includes a loading trough and a pushing mechanism. The loading trough is arranged on one side of the feeding trough for accommodating the rods to be processed, and the pushing mechanism is arranged on the frame for pushing the rods in the loading trough into the feeding trough one by one.

[0012] By adopting the above technical solution, the bars to be processed are placed in the loading trough, and then the pushing mechanism pushes the bars in the loading trough into the feeding trough one by one, thereby realizing the one-by-one loading operation of the bars into the feeding trough. The staff only needs to place the bars to be processed in the loading trough, making the loading operation of the bars convenient and quick, which is conducive to improving the processing efficiency of the bars.

[0013] Preferably, the lifting mechanism includes a lifting block, a linkage and a second driving member, the second driving member is arranged on the frame to drive the linkage to move along the length direction of the feeding trough, the linkage is connected to the lifting block to drive the lifting block to rotate, the lifting block includes a first rotating part and a lifting part that are fixedly connected, the first rotating part has a first rotating axis and a second rotating axis, the first rotating part is rotatably connected to the frame through the first rotating axis, the first rotating part is rotatably connected to the linkage through the second rotating axis, and the lifting part is located directly below the upper feeding trough.

[0014] By adopting the above technical solution, the second driving member drives the linkage member to move along the length direction of the feed trough, and the moving linkage member drives the lifting block to rotate through the cooperation of the first rotating axis and the second rotating axis. When the loading operation is required, the lifting part in the lifting block is lifted upward by the rotation of the first rotating part, so as to lift a rod in the feeding trough upward and slide it into the feed trough to realize the one-by-one loading of the rods. When the loading operation of one rod is completed, the lifting part is dropped downward by the reverse rotation of the first rotating part to facilitate the lifting and loading operation of the next rod.

[0015] Preferably, the linkage member includes a connecting block and a connecting plate, one end of the connecting plate is snap-connected to the connecting block, and the other end of the connecting plate is rotatably connected to the top material block through the second rotating axis. The end of the connecting plate connected to the connecting block is provided with a card hole for the connecting block to be snapped in, and the card hole has space for the connecting block to move, and the second driving member is used to drive the connecting block to move back and forth along the length direction of the feed trough.

[0016] By adopting the above technical solution, the second driving member drives the connecting block to move along the length direction of the feed trough, so that the connecting block drives the connecting plate to move along the length direction of the feed trough. During the movement, the connecting plate drives the lifting block to rotate along the first rotating axis through the second rotating axis, thereby realizing the lifting and falling action of the lifting part. The card hole has space for the connecting block to move, so that the connecting plate can adjust its position up and down during the movement along the length direction of the feed trough to facilitate the rotation operation of the lifting block.

[0017] Preferably, the separation mechanism includes a hook plate, a linkage plate and a third driving member, the hook plate includes a second rotating part and a hooking part that are fixedly connected, the second rotating part is horizontally rotatably connected to the linkage plate, the third driving member is arranged on the frame to drive the linkage plate to slide back and forth along the length direction of the feed trough, the side wall of the driving plate is provided with a slot for inserting the hooking part, and the separation mechanism also includes a magnetic member for making the hooking part have a tendency to move toward the feed trough.

[0018] By adopting the above technical solution, after the clamping mechanism clamps the bar tail, the third driving member drives the linkage plate to move in the direction away from the bar tail, and the linkage plate drives the hook plate to move synchronously in the direction away from the bar tail. During the movement of the hook plate, the magnetic member makes the hooking portion always abut against the side wall of the driving plate, and as the hooking portion moves, it is inserted into the slot opened in the driving plate. Through the snap-fit ​​cooperation between the hooking portion and the slot, the hook plate can drive the connecting plate to move in the direction away from the bar tail, and the driving plate then drives the pushing rod and the sleeve to move in the direction away from the bar tail, thereby realizing the pulling of the bar tail from the sleeve.

[0019] Preferably, the magnetic part includes a magnetic plate and a magnetic block that are magnetically matched. The magnetic plate is horizontally fixedly connected to the frame, the magnetic block is connected to the hooking portion, and the magnetic block is slidably connected to the side wall of the magnetic plate. The side wall of the magnetic plate is provided with a groove. When the magnetic block slides in the groove, the hooking portion is inserted into the slot. When the magnetic block slides outside the groove, the hooking portion passes through the slot.

[0020] By adopting the above technical solution, the magnetic plate and the magnetic block that are magnetically matched attract each other, so that the hooking part has a tendency to move toward the driving plate. When the magnetic block slides in the groove, the hooking part is inserted into the slot, and as the magnetic block moves in the groove, the hooking part is inserted into the slot to drive the driving plate to move in the direction away from the tail of the bar to realize the pulling operation. When the magnetic block slides out of the groove, the hooking part passes through the slot to avoid the pushing processing operation of the next bar.

[0021] Preferably, the magnetic block is configured as a magnetic wheel, and the magnetic wheel is rotatably connected to the lower end of the hooking portion.

[0022] By adopting the above technical solution, this setting is conducive to reducing the friction between the magnetic block and the magnetic plate, thereby helping to improve the smoothness of the movement of the magnetic block on the magnetic plate, thereby facilitating the material pulling operation.

[0023] Preferably, the side walls at both ends of the groove are arranged in the shape of arcs.

[0024] By adopting the above technical solution, this arrangement makes it easy for the magnetic wheel to slide out of the groove or slide into the groove during movement.

[0025] Preferably, the material pulling device further includes a collection box, and the collection box is located directly below the clamping mechanism.

[0026] By adopting the above technical solution, when the bar tailings are pulled out, the clamping mechanism releases the bar tailings, and the bar tailings fall into the collection box for collection. There is no need for manual cleaning of the bar tailings, which is simple and convenient.

[0027] A feeding method, using the above-mentioned feeding machine, comprises the following steps:

[0028] S1: Bar loading: The bar in the loading trough is transported one by one to the feeding trough through the lifting mechanism in the loading device, completing the automatic loading operation of the bar;

[0029] S2: Bar conveying. When the bar is loaded into the feeding trough, the first driving member pushes the push rod and the sleeve, so that the sleeve covers the bar and pushes the bar to the processing position for processing;

[0030] S3: Pulling out the bar tail. When the bar processing operation is completed, the clamping mechanism clamps and fixes the bar tail, and the separation mechanism drives the push rod and the sleeve to move quickly away from the bar tail to separate the bar tail and the sleeve. Then the clamping mechanism releases the bar tail, and the bar tail falls into the collection box for collection, and then the steps S1-S3 are repeated.

[0031] By adopting the above technical solution, when large-diameter bar processing operations are required, the pushing mechanism in the loading device transports the bars in the loading trough to the feed trough one by one, and then the first driving member pushes the pushing rod and the sleeve so that the sleeve covers the bar in the feed trough and pushes the bar to the processing position for processing operations. When the bar processing operation is completed, the clamping mechanism clamps and fixes the bar tail, and then the separation mechanism drives the pushing rod and the sleeve to move quickly in the direction away from the bar tail to separate the bar tail and the sleeve. Then the clamping mechanism releases the bar tail, and the bar tail falls into the collection box for collection. Repeating the above operations can complete the automatic loading and conveying processing of large-diameter bars. During the automatic loading and conveying processing of large-diameter bars, there is no need for manual assistance to pull out the tail, and the degree of automation is high, which is conducive to improving the processing efficiency of large-diameter bars.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By setting a clamping mechanism and a separating mechanism, when the bar processing operation is completed, the clamping mechanism clamps the bar tail, and then the separating mechanism drives the push rod and the sleeve to move quickly in the direction away from the bar tail, thereby realizing the operation of pulling the bar tail out of the sleeve, so as to facilitate the conveying and processing of the next bar. During the loading and conveying process of the bar, there is no need for manual assistance to pull out the tail, and the degree of automation is high, which is conducive to improving the processing efficiency of large-diameter bars.

[0034] 2. By setting a lifting block, a linkage member and a second driving member, the second driving member drives the linkage member to move along the length direction of the feed trough, and the moving linkage member drives the lifting block to rotate through the cooperation of the first rotating axis and the second rotating axis. When loading operation is required, the lifting part in the lifting block is lifted upward by the rotation of the first rotating part, so as to lift a bar in the feeding trough upward and slide it into the feeding trough to realize one-by-one loading of the bars. When the loading operation of one bar is completed, the lifting part is dropped downward by the reverse rotation of the first rotating part to facilitate the lifting and loading operation of the next bar.

[0035] 3. By setting a hook plate, a linkage plate, a third driving member and a magnetic member, when the clamping mechanism clamps the bar tail, the third driving member drives the linkage plate to move in the direction away from the bar tail, and the linkage plate drives the hook plate to move synchronously in the direction away from the bar tail. During the movement of the hook plate, the magnetic member makes the hook holding part always abut against the side wall of the driving plate, and as the hook holding part moves, it is inserted into the slot opened in the driving plate. Through the snap-fit ​​cooperation between the hook holding part and the slot, the hook plate can drive the connecting plate to move in the direction away from the bar tail, and the driving plate then drives the pushing rod and the sleeve to move in the direction away from the bar tail, thereby realizing the pulling out of the bar tail from the sleeve.

[0043] The following is combined with Figure 1-5 This application is described in further detail.

[0044] The present application embodiment discloses a feeder, referring to Figure 1 , including a frame 1, the frame 1 is provided with a feed trough 2 horizontally along its length, and one end of the feed trough 2 is the processing position of the bar. The frame 1 is also provided with a loading device 3, a pushing device 4 and a pulling device 5. The loading device 3 is provided on one side of the feed trough 2 for conveying the bars one by one into the feed trough 2. The pushing device 4 is provided at the end of the frame 1 away from the bar processing position for pushing the bars loaded into the feed trough 2 to the bar processing position for processing. The pulling device 5 is provided on the frame 1 for separating the processed bar tail from the pushing device 4, so as to facilitate the loading, conveying and processing operation of the next bar. During the loading and conveying process of the bar, there is no need for manual assistance to pull out the bar tail, and the degree of automation is high, which is conducive to improving the processing efficiency of large-diameter bars.

[0045] Reference Figure 1 and Figure 2 The loading device 3 includes a loading trough 31 and a pushing mechanism 32. The loading trough 31 is arranged on one side of the feeding trough 2 to accommodate the rods to be processed, and the loading trough 31 is parallel to the feeding trough 2. The pushing mechanism 32 is arranged on the frame 1 to push the rods in the loading trough 31 into the feeding trough 2 one by one. Specifically, the lifting mechanism 32 includes a lifting block 321, a linkage member 322 and a second driving member. The second driving member is arranged on the frame 1 to drive the linkage member 322 to move along the length direction of the feed trough 2. The linkage member 322 is connected to the lifting block 321 to drive the lifting block 321 to rotate up and down. When the lifting block 321 rotates upward, the lifting block 321 lifts a rod in the loading trough 31 upward so that a rod is transported and slides into the feed trough 2 located on one side of the loading trough 31. When the lifting block 321 rotates downward, a rod in the loading trough 31 moves onto the lifting block 321 to facilitate the next lifting operation.

[0046] Reference Figure 2 and Figure 3 The lifting block 321 includes an integrally formed first rotating part 3211 and a lifting part 3212. At the same time, the first rotating part 3211 has a first rotating axis 6 and a second rotating axis 7. The first rotating part 3211 is rotatably connected to the frame 1 through the first rotating axis 6, so that the lifting block 321 can be rotated up and down around the first rotating axis 6. The first rotating part 3211 is rotatably connected to the linkage part 322 through the second rotating axis 7, so that the movement of the linkage part 322 can drive the lifting part to rotate. The lifting part 3212 is located directly below the upper trough 31 to facilitate the lifting operation of the rod by the lifting part 3212.

[0047] Reference Figure 2The linkage part 322 includes a connecting block 3221 and a connecting plate 3222. One end of the connecting plate 3222 is snap-connected to the connecting block 3221, and the other end of the connecting plate 3222 is rotatably connected to the top material block 321 through the second rotating axis 7. The end of the connecting plate 3222 connected to the connecting block 3221 is provided with a card hole 8 for the connecting block 3221 to be snapped in. At the same time, the card hole 8 has space for the connecting block 3221 to move. The second driving member is used to drive the connecting block 3221 to move back and forth along the length direction of the feed trough 2. In this embodiment, the second driving member is configured as a second driving cylinder 323, and the second driving cylinder 323 is horizontally fixed on the frame 1. The piston rod of the second driving cylinder 323 is fixedly connected to the connecting block 3221. When the piston rod of the second driving cylinder 323 is stretched or contracted, the connecting block 3221 drives the connecting plate 3222 to move in the horizontal direction. Due to the presence of the card hole 8, the connecting plate 3222 can be adjusted to move up and down as a whole during the horizontal movement, so that the lifting block 321 can smoothly rotate up and down.

[0048] Reference Figure 1 、 Figure 2 and Figure 4 The pushing device 4 includes a first driving member 41, a pushing rod 42 and a sleeve 43. The sleeve 43 is fixedly arranged at one end of the pushing rod 42 facing the bar and is used to cover the tail of the bar to improve the stability of the bar during processing. The first driving member 41 is arranged on the frame 1 and is used to drive the pushing rod 42 to move along the length direction of the feed trough 2 to push the bar falling into the feed trough 2 to the processing position of the bar for processing.

[0049] Reference Figure 2 The first driving member 41 includes a sprocket 411, a chain 412, a drive plate 413 and a first drive motor 414. The number of sprockets 411 is set to two, and the two sprockets 411 are respectively connected to the two ends of the frame 1. The chain 412 is meshed around the two sprockets 411. One end of the drive plate 413 is fixedly connected to the chain 412, and the other end of the drive plate 413 is fixedly connected to the push rod 42. The first drive motor 414 is installed on the frame 1 for driving a sprocket 411 to rotate. In this embodiment, the first drive motor 414 drives the sprocket 411 to rotate through the reduction wheel group to improve the stability of the bar pushing process, which will not be described in detail here. It should be noted that the first drive motor 414 is selected as a servo motor that can rotate forward and reverse to drive the push rod 42 and the sleeve 43 to move back and forth in the feed trough 2, and the driving force of the servo motor is relatively gentle, which is conducive to improving the stability of the push rod 42 during the pushing operation.

[0050] Reference Figure 1 and Figure 2The pulling device 5 includes a clamping mechanism 51 and a separation mechanism 52. The clamping mechanism 51 is arranged at a position of the frame 1 close to the bar tail, and the separation mechanism 52 is arranged at one end of the frame 1 away from the bar processing position. When the bar processing operation is completed, the clamping mechanism 51 clamps and fixes the bar tail, and the separation mechanism 52 is used to drive the push rod 42 to move quickly in a direction away from the bar tail to separate the bar tail and the sleeve 43.

[0051] Reference Figure 1 and Figure 4 The clamping mechanism 51 includes an upper clamp 511 and a lower clamp 512 that move toward or away from each other. When the bar needs to be processed, the upper clamp 511 and the lower clamp 512 move toward and away from each other to avoid the pushing operation of the bar. When the processing operation of the bar is completed, the upper clamp 511 and the lower clamp 512 move toward and toward each other to clamp the bar tail, thereby facilitating the separation mechanism 52 to perform the pulling operation.

[0052] Reference Figure 2 and Figure 5 The separation mechanism 52 includes a hook plate 521, a linkage plate 522, and a third driving member. The hook plate 521 includes an integrally formed second rotating portion 5211 and a hooking portion 5212. The linkage plate 522 is horizontally arranged, and the second rotating portion 5211 is horizontally connected to the linkage plate 522 for rotation. The third driving member is disposed on the frame 1 and is used to drive the linkage plate 522 to slide back and forth along the length of the feed chute 2. Simultaneously, a slot 9 is defined in the sidewall of the drive plate 413 for insertion of the hooking portion 5212. When the hooking portion 5212 is inserted into the slot 9, the movement of the linkage plate 522 can drive the movement of the drive plate 413 via the hook plate 521, thereby separating the sleeve 43 from the bar tail.

[0053] Reference Figure 5, the separation mechanism 52 also includes a magnetic member 524 for causing the hooking portion 5212 to have a tendency to move toward the drive plate 413. Specifically, the magnetic member 524 includes a magnetic plate 5241 and a magnetic block that are magnetically matched. The magnetic plate 5241 is horizontally fixedly connected to the frame 1, and the magnetic block is connected to the hooking portion 5212. The magnetic block is slidably connected to the side wall of the magnetic plate 5241, and the side wall of the magnetic plate 5241 is provided with a groove 10. When the magnetic block moves on the side wall of the magnetic plate 5241, due to the setting of the groove 10, the hooking portion 5212 can be inserted into or out of the slot 9. When the magnetic block slides in the groove 10, the hooking portion 5212 is inserted into the slot 9. When the magnetic block slides outside the groove 10, the hooking portion 5212 passes through the slot 9. In this embodiment, the magnetic block is configured as a magnetic wheel 5242, which is horizontally rotatably connected to the lower end of the hook portion 5212, and the wheel surface of the magnetic wheel 5242 is rollingly connected to the side wall of the magnetic plate 5241. In addition, the side walls of the groove 10 are designed to be circular arcs to reduce the friction between the magnetic wheel 5242 and the magnetic plate 5241, thereby facilitating smoother movement of the magnetic wheel 5242 on the magnetic plate 5241.

[0054] When the material extraction operation is required, the upper chuck 511 and the lower chuck 512 cooperate to clamp the bar tail, and then the third driving member drives the linkage plate 522 to move in the direction away from the bar tail. The linkage plate 522 synchronously drives the hook plate 521 to move in the direction away from the bar tail. At this time, the magnetic wheel 5242 falls into the groove 10 of the magnetic plate 5241, and the hook portion 5212 is inserted into the slot 9. As the linkage plate 522 continues to move, the hook portion 5212 drives the driving plate 413 to move in the direction away from the bar tail by inserting into the slot 9, thereby realizing the extraction operation of the bar tail from the sleeve 43. After the bar tail is extracted, the magnetic wheel 5242 slides out of the groove 10 of the magnetic plate 5241, so that the hook portion 5212 passes through the slot 9. It should be noted that the third driving member is configured as a third driving cylinder 523, and the third driving cylinder 523 is horizontally fixed on the frame 1. The piston rod of the third driving cylinder 523 is fixedly connected to the linkage plate 522. The stretching or contraction of the piston rod of the third driving cylinder 523 drives the linkage plate 522 to move back and forth, thereby realizing that the hooking portion 5212 of the hook plate 521 drives the sleeve 43 to move toward or away from the clamped and fixed rod tail through the slot 9 of the driving plate 413, and the kinetic energy impact force of the third driving cylinder 523 is relatively large, which is convenient for the material pulling operation.

[0055] Reference Figure 1 The pulling device 5 also includes a collecting box 53, which is located directly below the clamping mechanism 51 to collect the bar tailings after the pulling operation and facilitate the feeding and conveying processing operation of the next bar.

[0056] The present application also discloses a feeding method using the above-mentioned feeding machine, comprising the following steps:

[0057] S1: Bar loading: The piston rod of the second driving cylinder 323 is stretched or contracted, driving the connecting plate 3222 to move horizontally through the connecting block 3221. The presence of the clamping hole 8 allows the connecting plate 3222 to be adjusted up and down during the horizontal movement, so that the ejecting block 321 can be rotated up and down, thereby ejecting the bars one by one into the feeding trough 2, completing the automatic loading operation of the bars;

[0058] S2: Pushing the bar material. The first driving motor 414 drives the sprocket 411 to rotate through the reduction wheel group. The two sprockets 411 drive the driving plate 413 to move along the length direction of the feeding trough 2 through the chain 412 meshing therewith, so that the sleeve 43 covers the bar material falling into the feeding trough 2 and pushes the bar material to the processing position for processing.

[0059] S3: pulling out the bar tail. When the bar processing operation is completed, the upper chuck 511 and the lower chuck 512 cooperate to clamp the bar tail. Then the third driving cylinder 523 drives the linkage plate 522 to move in the direction away from the bar tail. The linkage plate 522 synchronously drives the hook plate 521 to move in the direction away from the bar tail. At this time, the magnetic wheel 5242 falls into the groove 10 of the magnetic plate 5241, and the hook holding part 5212 is inserted into the slot 9. As the linkage plate 522 continues to move, the hook holding part 5212 is inserted into the slot 9. The dynamic driving plate 413 moves in the direction away from the bar tail, thereby realizing the operation of pulling the bar tail out of the sleeve 43. After the bar tail is pulled out of the sleeve 43, the upper clamp 511 and the lower clamp 512 loosen the bar tail, so that the bar tail falls into the collection box 53 for collection, and the above steps S1-S3 are repeated to realize the continuous action of bar loading and conveying processing. During the bar loading and conveying processing, there is no need for manual assistance in pulling out the tail, and the degree of automation is high, which is conducive to improving the processing efficiency of large-diameter bars.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
