Description

Technical Field

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

[0002] In the production process, bars usually need to be processed by CNC machine tools. When feeding bars into CNC machine tools, due to their long length and heavy volume, if they are fed manually, multiple workers are required to assist in pushing them. This method is time-consuming and labor-intensive, and is also more likely to cause safety hazards. Therefore, automatic bar feeding devices have been used to automatically feed bars.

[0003] In the prior art, when automatically feeding bars, most of them require the assistance of robots, which has the problems of complex structure, difficult assembly and high cost. In addition, since there may be residual bar tails after the processing of the bars, if the bar tails are not recycled in time, it may affect the subsequent feeding, and even cause the next bar to be fed to collide with the residual bar tails, resulting in material jamming, which leads to low feeding efficiency and affects the feeding quality.

[0006] By adopting the above-mentioned technical solution, the present application controls multiple different mechanisms of the feeding device through a driving mechanism, so that they cooperate with each other to automatically feed, clamp and feed the rods, thereby simplifying the equipment structure and reducing the difficulty of assembly. At the same time, a tailing recovery trough is provided to recover the processed rod tailings, so as to reduce the impact of the rod tailings on subsequent feeding, and improve the feeding efficiency and feeding quality of the feeding device.

[0007] Further, the feeding mechanism includes a plurality of feeding components and a feeding rack, the feeding rack is obliquely mounted on one side of the feeding trough, and the plurality of feeding components are mounted on the feeding rack; The feeding assembly includes a supporting block and a pushing block, the supporting block is fixedly connected to the feeding rack to form a feeding trough, the supporting block is provided with a protrusion at one end of the feeding trough close to the feeding trough, the pushing block is slidably connected to the supporting block, the pushing block is used to move toward the feeding trough until it is flush with the protrusion so that the feeding mechanism starts feeding, and to move away from the feeding trough so that the feeding mechanism stops feeding.

[0008] By adopting the above technical solution, the present application lifts the rod from the feed rack by moving the lifting block of the feed assembly, and enters the feeding trough through the feed trough, thereby ensuring the reliability of the feeding process.

[0013] Furthermore, the clamping mechanism includes a clamping assembly, which includes two clamping parts. The two clamping parts are respectively located on both sides of an end of the feeding trough away from the discharge port. The two clamping parts are used to clamp the clamping assembly when they are close to each other and to loosen the clamping assembly when they are away from each other.

[0014] By adopting the above-mentioned technical scheme, the present application controls the clamping member to move closer or further away to clamp or loosen the rod placed on the feeding trough. When clamping, it can cooperate with the pushing mechanism to insert the push rod into the rod. When loosening, it can enable the pushing mechanism to feed stably, thereby ensuring the reliability of the clamping and feeding process.

[0015] Furthermore, the clamping mechanism also includes a transmission assembly, which includes a moving block and two transmission plates, the two transmission plates are respectively located on both sides of the feeding trough, the middle part of the transmission plate is rotatably fixed to the frame through a rotating shaft, and a limiting groove is provided on the inner side of the transmission plate; A limiting column is provided on the top of the moving block, and the limiting column is used to abut against the limiting groove when the moving block moves away from the clamping assembly, so that the abutment between the transmission plate and the limiting column rotates outward around the rotating shaft; The two transmission plates are respectively connected to the outer sides of the two clamping members, and the transmission plates are used to make the two clamping members approach each other when rotating around the inner side of the rotating shaft, and make the two clamping members move away from each other when rotating around the outer side of the rotating shaft.

[0018] By adopting the above technical solution, the driving mechanism of the present application converts the rotation of the motor output shaft into movement of the driving rod toward or away from the feed trough through the cooperation of the first gear and the first rack, thereby ensuring the stability of the drive.

[0019] Furthermore, the moving block is mounted on the upper surface of the driving rod, and a first inclined block and a second inclined block are respectively provided on both sides of the connection between the driving rod and the feeding mechanism; The first connecting rod is embedded with a first limit block, the first limit block abuts against the inclined surface of the first inclined block through a first cylinder, and the first cylinder is used to move upward along the inclined surface of the first inclined block when the first inclined block moves away from the feeding trough under the drive rod; The second connecting rod is embedded with a second limit block, which abuts against the inclined surface of the second inclined block through a second cylinder.

The movement of the second inclined block can drive the baffle assembly to close or open. The operation of multiple mechanisms can be controlled by one driving mechanism, which further simplifies the equipment structure, reduces costs, and ensures the stability and reliability of feeding.

[0021] In the second aspect, the present application provides a control method for an automatic bar feeding device using the following technical solution: A control method for an automatic bar feeding device, applied to the automatic bar feeding device described in the first aspect, comprises: The starting position of the push mechanism is the rear origin position. When receiving the automatic feeding signal, the controller sends a forward signal to the drive mechanism, so that the drive mechanism drives the feeding mechanism to feed; When receiving the feeding completion signal, the controller sends a reverse signal to the driving mechanism, so that the driving mechanism drives the clamping mechanism to clamp the bar; When receiving the clamping completion signal, the controller controls the pushing assembly to drive the push rod to move toward the feeding trough so that the push rod is inserted into the bar; When receiving the insertion completion signal, the controller controls the driving mechanism to drive the clamping mechanism to release the rod, and the controller sends a forward instruction to control the pushing mechanism to push the rod to move toward the discharge port.

[0022] By adopting the above-mentioned technical scheme, the control method of the present application includes feeding process control. When a feeding signal is received, it means that the feeding process needs to be carried out currently. The controller can simultaneously control the feeding mechanism, the baffle assembly and the clamping mechanism by controlling the driving mechanism to realize feeding and clamping, and then drive the push rod by controlling the pushing assembly to push the bar to move toward the discharge port, thereby completing the feeding process. No manual operation is required, automatic feeding is realized, and the reliability of the feeding process is ensured, thereby improving the feeding efficiency and feeding quality.

[0023] Furthermore, it also includes: When receiving the processing completion signal, the controller sends a backward instruction to control the pusher mechanism to move toward the rear origin position; When the pusher mechanism moves to the rear origin position, the controller detects whether there is a bar tailing at present; When there is bar tailing, the controller controls the driving mechanism to drive the clamping mechanism to clamp the bar tailing; The controller controls the pushing assembly to drive the push rod to move away from the feeding trough, so that the push rod is pulled out from the tail of the bar material; The controller controls the driving mechanism to drive the clamping mechanism to release the bar tailings, so that the bar tailings enter the tailings recovery tank.

[0024] By adopting the above technical solution, since the bar is processed outside the discharge port after feeding, there may be bar tailings in the bar after processing. When the processing completion signal is received, that is, after the bar processing is completed, the present application detects whether there are bar tailings at present. When there are bar tailings, a tailing recovery process is carried out to recover the bar tailings to the tailing recovery tank to ensure that the subsequent feeding will not be affected by the existence of tailings, thereby improving the feeding quality of the bar.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application controls multiple different mechanisms of the feeding device through a driving mechanism, so that they cooperate with each other to automatically feed, clamp and feed the bar material, thereby simplifying the equipment structure and reducing the difficulty of assembly. At the same time, a tailing recovery trough is provided to recover the processed bar tailings, so as to reduce the influence of the bar tailings on the subsequent feeding, and improve the feeding efficiency and feeding quality of the feeding device; 2. The present application shields and protects the feeding trough through a baffle assembly, and drives the first baffle to open and close through the second connecting rod. When the baffle needs to be opened during the feeding process, the second connecting rod drives the first baffle away from the feeding trough. When the baffle needs to be closed after the feeding process, the second connecting rod drives the first baffle close to the feeding trough, thereby protecting the feeding trough and ensuring the reliability of the feeding process. 3. The present application controls the clamping member to move closer or farther away to clamp or loosen the bar placed on the feeding trough. When clamping, it can cooperate with the pushing mechanism to insert the push rod into the bar. When loosening, it can enable the pushing mechanism to feed stably, thereby ensuring the reliability of the clamping and feeding process; 4. In the present application, the movement of the driving rod can simultaneously drive the movement of the moving block, the first limit block and the second limit block. The movement of the moving block can drive the clamping assembly to clamp or loosen. The movement of the first limit block can drive the feeding mechanism to feed or stop. The movement of the second limit block can drive the baffle assembly to close or open.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0028] In the technology of automatic feeding of bars, most of them require the assistance of a robot, which has the problems of complex structure, difficult assembly and high cost. In addition, since there may be residual bar tails left after the processing of the bars, if the bar tails are not recycled in time, it may affect the subsequent feeding, and even cause the residual bar tails to collide with the next bar to be fed, resulting in material jamming, which leads to low feeding efficiency and affects the feeding quality. Therefore, the embodiment of the present application provides an automatic feeding device for bars, referring to Figure 1 , including a frame 1, a feed trough 2, a feeding mechanism 3, a clamping mechanism 4, a pushing mechanism 5 and a tail material recovery trough 6, the feed trough 2 is installed on the frame 1, the feeding mechanism 3 is located at one side of the feed trough 2, one end of the feed trough 2 is provided with a discharge port 21, the pushing mechanism 5 is located at the end of the feed trough 2 away from the discharge port 21, the clamping mechanism 4 is located between the pushing mechanism 5 and the feed trough 2, the tail material recovery trough 6 is located below the clamping mechanism 4, and a baffle assembly 22 is provided above the feed trough 2.

[0029] The apparatus further includes a driving mechanism 7 and a controller 8, wherein the driving mechanism 7 and the pushing mechanism are respectively connected to the controller 8 for communication and are controlled by the controller 8. The driving mechanism 7 is connected to the feeding mechanism 3, the baffle assembly 22 and the clamping mechanism 4, and is used to drive the feeding mechanism 3 to feed or stop, drive the baffle assembly 22 to close or open, and drive the clamping assembly 41 to clamp or release. In the specific implementation process, the controller 8 can adopt a PLC control system.

[0030] The implementation principle of the embodiment of the present application is as follows: during the feeding process, the feeding mechanism 3 is used to store the rods to be fed and to feed the rods to the feeding trough 2 when feeding is required. The feeding trough 2 is used to place the rods. The clamping mechanism 4 is used to clamp one end of the rods and cooperate with the pushing mechanism 5. The pushing mechanism 5 is used to move the rods close to the discharge port 21. During the tailing recovery process, the pushing mechanism 5 is used to move the rod tails away from the discharge port 21. The clamping mechanism 4 is used to clamp the rod tails and cooperate with the pushing mechanism 5 to make the rod tails fall to the tailing recovery trough 6. The tailing recovery trough 6 is used to store the rod tails after processing, thereby realizing fully automated feeding and tailing recovery. A driving mechanism 7 is used to control multiple different mechanisms of the feeding device, so that they cooperate with each other to automatically feed, clamp and feed the bars, thereby simplifying the equipment structure and reducing the difficulty of assembly. At the same time, a tailing recovery trough 6 is provided to recover the processed bar tailings, so as to reduce the impact of the bar tailings on subsequent feeding, thereby improving the feeding efficiency and feeding quality of the feeding device.

[0031] In the specific implementation process, the frame 1 serves as the basic supporting structure of the entire automatic feeding device. The frame 1 needs to be stable and reliable, and be able to withstand various forces and vibrations generated during the processing. The frame 1 is used to support the feeding trough 2, the feeding mechanism 3, the clamping mechanism 4, the pushing mechanism 5, and the tail material recovery trough and other components. The feeding trough 2 is the passage for the rods from the feeding mechanism 3 to the processing area. Its design should ensure that the rods can be transported smoothly and continuously. The shape, size and surface material of the feeding trough 2 need to be optimized according to the characteristics of the rods and the processing requirements to reduce friction and wear. The feeding mechanism 3 is used to introduce the rods to be processed from the outside into the feeding trough 2. It can include one or more sensors to detect the presence of the rods and trigger the subsequent feeding action. The feeding mechanism 3 can also include an automatic adjustment device to adapt to rods of different diameters or lengths. The clamping mechanism 4 is used to firmly clamp the bar before it enters the processing area to prevent it from moving or slipping during the processing. The design of the clamping mechanism 4 should ensure that the clamping force is moderate, which can stably clamp the bar without damaging its surface. At the same time, the clamping mechanism 4 should also have the ability to respond quickly and clamp accurately to adapt to bars of different specifications and materials. The pushing mechanism 5 is used to push the bar from the feeding trough 2 to the processing area, and can accurately control the pushing distance and speed. The pushing mechanism 5 should also have an overload protection function to prevent the equipment from being damaged due to the jamming of the bar or excessive resistance during the pushing process. The tailings recovery trough is used to collect the remaining bar tailings after the processing is completed. These tailings may not be used anymore due to insufficient length or processing defects, but they can be recycled and reused to reduce waste. The design of the tailings recovery trough should be easy to clean and maintain, and have a certain storage capacity to cope with the processing needs of different batches.

[0032] like Figure 1 and Figure 2As shown, the feeding mechanism 3 includes a plurality of feeding components 31 and a feeding rack 32. The feeding rack 32 is obliquely installed on one side of the feeding trough 2. The plurality of feeding components 31 are installed on the feeding rack 32. The feeding rack 32 is used to store the bars to be fed. The feeding component 31 includes a support block 311 and a top block 312. The support block 311 is fixedly connected with the feeding rack 32 to form a feeding trough. The support block 311 is provided with a protrusion 313 at one end of the feeding trough close to the feeding trough 2. The top block 312 is slidably connected with the support block 311. The top block 312 is used to start feeding the feeding mechanism 3 when it moves toward the feeding trough until it is flush with the protrusion 313, and stop feeding the feeding mechanism 3 when it moves away from the feeding trough. The plurality of feeding components 31 are connected by a rotatable first connecting rod 33. A rotating connecting block 331 is provided at the connection between the first connecting rod 33 and the feeding component 31. One end of the rotating connection block 331 is sleeved outside the first connecting rod 33, and the other end of the rotating connection block 331 is connected to the end of the ejecting block 312 away from the feed slot. The first connecting rod 33 is used to drive the ejecting block 312 to move toward the feed slot when rotating clockwise, and to drive the ejecting block 312 to move away from the feed slot when rotating counterclockwise. In the specific implementation process, the rotation direction is clockwise rotation and counterclockwise rotation when viewed from the discharge port 21 to the pushing mechanism 5.

[0033] When feeding is not needed, the feeding rods are stored on the feeding rack 32. Due to the limiting effect of the protrusion 313, the rods are fixed on the feeding rack 32 and will not slide downward. When feeding is needed, the driving mechanism 7 controls the first connecting rod 33 to rotate clockwise, driving the lifting block 312 to move toward the feeding trough, and lifting the rods toward the feeding trough 2. When the top of the lifting block 312 moves to be flush with the protrusion 313, the limiting effect of the protrusion 313 disappears. Due to the inclination angle of the feeding rack 32, the rods move downward along the feeding trough to the feeding trough 2, thereby realizing the feeding process.

[0034] like Figure 1 and Figure 2 As shown, the baffle assembly 22 includes a first baffle 221, a plurality of baffle connecting blocks 222 and a second connecting rod 223, the second connecting rod 223 is rotatably mounted on a side of the feed trough 2 away from the feeding mechanism 3, a plurality of baffle connecting blocks 222 connect the first baffle 221 and the second connecting rod 223, and the second connecting rod 223 is used to make the first baffle 221 close to the feed trough 2 when rotating clockwise, and to make the first baffle 221 away from the feed trough 2 when rotating counterclockwise. In the specific implementation process, the rotation direction is clockwise rotation and counterclockwise rotation viewed from the discharge port 21 to the pushing mechanism 5.

[0035] When feeding is not required, the control mechanism controls the second connecting rod 223 to rotate clockwise to drive the first baffle 221 close to the feeding trough 2, so that the first baffle 221 is closed to shield and protect the feeding trough 2. When feeding is required, the control mechanism controls the second connecting rod 223 to rotate counterclockwise to drive the first baffle 221 away from the feeding trough 2, so that the first baffle 221 is opened, so that the bar material passes through the feeding trough and enters the feeding trough 2.

[0036] like Figure 1 and Figure 3 As shown, the clamping mechanism 4 includes a clamping assembly 41 and a transmission assembly 42. The clamping assembly 41 includes two clamping members 411, which are respectively located on both sides of the end of the feeding trough 2 away from the discharge port 21. The clamping members 411 are fixedly connected to the frame 1 through a spring. The two clamping members 411 are used to clamp the clamping assembly 41 when they are close to each other and to loosen the clamping assembly 41 when they are away from each other. The transmission assembly 42 includes a moving block 421 and two transmission plates 422, which are respectively located on both sides of the feeding trough 2. The middle part of the transmission plate 422 is rotatably fixed to the frame 1 through a rotating shaft, and a limiting groove 4221 is provided on the inner side of the transmission plate 422. A limiting column 4211 is provided on the top of the moving block 421. The limiting column 4211 is used to abut against the limiting groove 4221 when the moving block 421 moves away from the clamping assembly 41, so that the abutment between the transmission plate 422 and the limiting column 4211 rotates outward around the rotation axis. The two transmission plates 422 are respectively connected to the outside of the two clamping members 411. The transmission plates 422 are used to make the two clamping members 411 approach each other when rotating inward around the rotation axis, and to make the two clamping members 411 move away from each other when rotating outward around the rotation axis.

[0037] When there is no need to clamp materials, the elastic force of the spring keeps the two clamping members 411 away from each other, the clamping assembly 41 is loosened, the moving block 421 approaches the clamping assembly 41, the two transmission plates 422 maintain the initial state, and the limiting column 4211 and the limiting groove 4221 remain non-contacting. When clamping materials is needed, the moving block 421 moves in the direction away from the clamping assembly 41, so that the limiting column 4211 approaches the limiting groove 4221 until it abuts against the limiting groove 4221. Under the limiting action of the limiting column 4211 and the limiting groove 4221, the end of the transmission plate 422 provided with the limiting groove 4221 moves outward. Since the middle part of the transmission plate 422 is fixed by a rotating shaft, the end of the transmission plate 422 connected to the clamping member 411 moves inward, so that the clamping member 411 moves inward, so that the two clamping members 411 are close to each other, and the clamping assembly 41 is clamped, thereby realizing the material clamping process.

[0038] like Figure 1 , Figure 3 and Figure 4As shown, the driving mechanism 7 includes a motor 71, a first gear 72, a first rack 73 and a driving rod 74, the first gear 72 is nested in the output shaft of the motor 71, the first gear 72 and the first rack 73 are meshed with each other, the first rack 73 is installed on the upper surface of the driving rod 74, the end of the driving rod 74 away from the motor 71 passes through the clamping mechanism 4 and is connected to the feeding mechanism 3, and the motor 71 is used to drive the driving rod 74 to move towards or away from the feeding trough 2. The moving block 421 of the transmission assembly 42 is installed on the upper surface of the middle part of the driving rod 74, and the first inclined block 741 and the second inclined block 742 are respectively provided on both sides of the connection between the driving rod 74 and the feeding mechanism 3. The moving block 421, the first inclined block 741 and the second inclined block 742 can be driven to clamp or release the clamping assembly 41 at the same time by the movement of the driving rod 74. The movement of the first inclined block 741 can drive the feeding mechanism 3 to feed or stop, and the movement of the second inclined block 742 can drive the baffle assembly 22 to close or open. In the specific implementation process, the motor 71 adopts a reduction motor.

[0039] like Figure 1 and Figure 4 As shown, the first connecting rod 33 is embedded with a first limiting block 743, and the first limiting block 743 abuts against the inclined surface of the first inclined block 741 through the first cylinder 744. The first cylinder 744 is used to move upward along the inclined surface of the first inclined block 741 when the first inclined block 741 moves away from the feeding trough 2 under the drive rod 74. In the specific implementation process, when the drive rod 74 moves away from the feeding trough 2, the first inclined block 741 moves away from the discharge port 21 synchronously, and the first cylinder 744 moves along the inclined surface of the first inclined block 741 to the upper oblique direction close to the discharge port 21. Since the first limiting block 743 is embedded outside the first connecting rod 33, it drives the first limiting block 743 to move obliquely upward, thereby driving the first connecting rod 33 to rotate counterclockwise, so that the top material block 312 moves away from the feeding trough, limiting the feeding of the bar material placed on the feeding rack 32. When the driving rod 74 moves toward the direction close to the feed trough 2, the first inclined block 741 synchronously moves toward the direction close to the discharge port 21, and the first cylinder 744 moves along the inclined surface of the first inclined block 741 toward the oblique downward direction away from the discharge port 21. Since the first limit block 743 is nested outside the first connecting rod 33, it drives the first limit block 743 to move obliquely downward, thereby driving the first connecting rod 33 to rotate clockwise, causing the pushing block 312 to move toward the feed trough, pushing the rods placed on the feed rack 32 to the feed trough 2, completing the process of controlling the feeding assembly 31 to feed by the driving mechanism 7.

[0040] like Figure 1 and Figure 4As shown, the second connecting rod 223 is embedded with a second stopper 745, and the second stopper 745 abuts against the inclined surface of the second inclined block 742 through the second cylinder 746. The second cylinder 746 is used to move upward along the inclined surface of the second inclined block 742 when the second inclined block 742 moves away from the feeding trough 2 under the drive rod 74. In the specific implementation process, when the drive rod 74 moves away from the feeding trough 2, the second inclined block 742 moves away from the discharge port 21 synchronously, and the second cylinder 746 moves along the inclined surface of the second inclined block 742 to the upper oblique direction close to the discharge port 21. Since the second stopper 745 is embedded outside the second connecting rod 223, the second stopper 745 is driven to move obliquely upward, thereby driving the first connecting rod 33 to rotate clockwise, so that the baffle connecting block 222 rotates in the direction close to the feeding trough 2, so that the first baffle 221 is closed. When the driving rod 74 moves toward the direction close to the feed trough 2, the second inclined block 742 synchronously moves toward the direction close to the discharge port 21, and the second cylinder 746 moves along the inclined surface of the second inclined block 742 toward the oblique downward direction away from the discharge port 21. Since the second limit block 745 is nested outside the second connecting rod 223, it drives the second limit block 745 to move obliquely downward, thereby driving the second connecting rod 223 to rotate counterclockwise, causing the baffle connecting block 222 to rotate in the direction away from the feed trough 2, thereby opening the first baffle 221, completing the process of controlling the opening and closing of the baffle assembly 22 through the driving mechanism 7.

[0041] In the specific implementation process, the first inclined block 741 and the second inclined block 742 have different inclinations, and the specific inclination is set according to the required moving distance of the top block 312 and the required opening degree of the first baffle 221, that is, according to the required rotation amplitude of the first connecting rod 33 and the second connecting rod 223. During the feeding process, by moving the driving rod 74 toward the feeding trough 2, the feeding assembly 31 can be started to feed, the baffle assembly 22 can be opened, and the clamping assembly 41 can be released synchronously, so that the bar can stably enter the feeding trough 2.

[0042] like Figure 1 and Figure 5 As shown, the pushing mechanism 5 includes a pushing assembly 51 and a pushing rod 52. The pushing rod 52 is used to be inserted into the bar material and move along the feeding trough 2 under the drive of the pushing assembly 51, so that the bar material moves toward or away from the discharge port 21. The pushing assembly 51 includes a second gear 511 and a second rack 512. The second gear 511 is mounted on an end of the frame 1 away from the discharge port 21. The second rack 512 is meshed with the second gear 511. The pushing rod 52 is fixedly connected to the second rack 512. Under the drive of the second gear 511, the second rack 512 drives the pushing rod 52 to move toward or away from the discharge port 21.

[0043] In the specific implementation process, after the bar has been placed on the feeding trough 2 through the feeding mechanism 3, the driving mechanism 7 drives the clamping mechanism 4 to clamp the end of the bar close to the pushing mechanism 5, and the pushing component 51 drives the push rod 52 to approach the bar, so that the push rod 52 is inserted into the inside of the bar, and then the driving mechanism 7 drives the clamping mechanism 4 to release the bar, so that the push rod 52 pushes the bar to move in the direction close to the discharge port 21, thereby realizing the feeding process. After the bar processing is completed, the pushing component 51 drives the push rod 52 to move away from the discharge port 21 until the push rod 52 moves to the initial position. When the presence of bar tail is detected, the driving mechanism 7 drives the clamping mechanism 4 to clamp the bar tail, and the pushing component 51 drives the push rod 52 to continue to move away from the discharge port 21, so that the push rod 52 is pulled out from the bar tail, and the driving mechanism 7 drives the clamping mechanism 4 to release the bar tail, so that the bar tail falls into the tail recovery trough 6 below the clamping mechanism 4, thereby realizing the tail recovery process.

[0044] In the specific implementation process, the bottom of the tailings recovery tank 6 is a pull-out structure. After a certain amount of rod tailings are recovered, the rod tailings in the tailings recovery tank 6 can be further recycled by pulling out the pull-out structure.

[0045] In a preferred embodiment, the discharge port 21 of the embodiment of the present application is provided with a telescopic sleeve, which can ensure that the rods sent out from the discharge port 21 can accurately enter the external processing equipment. The bottom of the frame 1 is a telescopic structure, and the height of the frame 1 can be adjusted accordingly according to the height of the external processing equipment to ensure that the discharge port 21 can be aligned with the external processing equipment.

[0046] The present application also provides a control method for an automatic bar feeding device, which is applied to an automatic bar feeding device. Figure 6 , the control method includes the feeding process: S1. The starting position of the pushing mechanism 5 is the rear origin position. When receiving the automatic feeding signal, the controller 8 sends a forward signal to the driving mechanism 7, so that the driving mechanism 7 drives the feeding mechanism to feed.

[0047] Specifically, the rear origin position is the starting position of the push mechanism 5, that is, the position away from the discharge port. The automatic feeding signal can be generated by the staff operating the touch device or control button, or it can be automatically generated by the external processing equipment and sent to the controller 8. The controller 8 starts the feeding process after receiving the feeding signal. The controller 8 can adopt a PLC control system, and the drive mechanism 7 can adopt a servo motor or a reduction motor, so as to receive the forward signal and reverse signal sent by the controller 8.

[0048] S2. When receiving the feeding completion signal, the controller 8 sends a reverse signal to the driving mechanism 7, so that the driving mechanism 7 drives the clamping mechanism 4 to clamp the bar.

[0049] Specifically, a sensing device is provided on the feeding trough 2. When the sensing device senses that the bar has been placed on the feeding trough 2, a feeding completion signal is generated and sent to the controller 8. The controller 8 starts the material clamping process upon receiving the feeding completion signal.

[0050] S3. When receiving the clamping completion signal, the controller 8 controls the pushing assembly 51 to drive the push rod 52 to move toward the feeding trough 2 so that the push rod 52 is inserted into the rod.

[0051] Specifically, after the clamping process is completed, the controller 8 controls the pushing mechanism 5 and the clamping mechanism 4 to cooperate to insert the push rod 52 into the rod.

[0052] S4. When receiving the insertion completion signal, the controller 8 controls the driving mechanism 7 to drive the clamping mechanism 4 to release the rod, and the controller 8 issues a forward instruction to control the pushing mechanism 5 to push the rod to move toward the discharge port 21.

[0053] Specifically, the clamping mechanism 4 is controlled to be loosened so that the pushing mechanism 5 can move the bar toward the discharge port 21 , so that the bar is discharged from the discharge port 21 , thereby completing the feeding process.

[0054] like Figure 7 As shown, the control method of the embodiment of the present application also includes a tailings recovery process: S5. When receiving the processing completion signal, the controller 8 issues a backward instruction to control the pushing mechanism 5 to move toward the rear origin position.

[0055] Specifically, after the external processing equipment completes processing of the bar material, a processing completion signal is generated and sent to the controller 8. After receiving the processing completion signal, the controller 8 can control the pushing mechanism 5 to return to the initial position, that is, the rear origin position.

[0056] S6. When the pushing mechanism 5 moves to the rear origin position, the controller 8 detects whether there is any bar tailing.

[0057] Specifically, a sensing device can be provided on the surface of the middle part of the clamping mechanism 4 close to the feeding trough 2 to sense whether there is a bar tail on the current push rod 52. S7. When there is bar tailing, the controller 8 controls the driving mechanism 7 to drive the clamping mechanism 4 to clamp the bar tailing.

[0058] Specifically, if there is any bar tailing, the sensing device generates a tailing recovery signal, and the controller 8 automatically starts the tailing recovery process upon receiving the tailing recovery signal.

[0059] S8. The controller 8 controls the pushing assembly 51 to drive the push rod 52 to move away from the feeding trough 2, so that the push rod 52 is pulled out from the bar tail.

[0060] S9, the controller 8 controls the driving mechanism 7 to drive the clamping mechanism 4 to release the bar tailings, so that the bar tailings enter the tailings recovery slot 6.

[0061] Specifically, the clamping mechanism 4 and the pushing mechanism cooperate with each other to pull the bar tailings out from the push rod 52 and drop them into the tailings recovery slot 6 below the clamping mechanism 4, thereby completing the tailings recovery process.

[0062] In the specific implementation process, the control method of the automatic bar feeding device of the embodiment of the present application is usually implemented based on PLC (programmable logic controller) or other automatic control systems. The core of the control method is to achieve the coordinated work between the various components to ensure the continuity and stability of the entire feeding process. Specific functions include: start-up, after the power is turned on, the system enters the standby state and waits for the external start signal. Feed detection, the sensor detects whether there are bars in the feeding trough 2, and if they are in place, the feeding action is triggered. Clamping and pushing, after the clamping mechanism 4 clamps the bar, the pushing mechanism 5 starts to push the bar to the processing area. Processing monitoring, during the processing, the control system continuously monitors the operating status of each component to ensure that no abnormalities occur. Tailing recovery, after the processing is completed, the remaining tailings are sent to the tailing recovery trough for collection. Cycle and stop, according to production needs, the system automatically enters the next working cycle or stops working.

[0063] The implementation principle of the embodiment of the present application is: by integrating key components such as the frame 1, the feeding trough 2, the feeding mechanism 3, the clamping mechanism 4, the pushing mechanism 5 and the tailing recovery trough, and adopting advanced automation control technology, the automatic feeding and tailing recovery functions in the bar processing process are realized, thereby improving production efficiency and resource utilization.

[0064] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
