Description

Technical Field

[0001] This application relates to the technical field of automatic feeding devices, and particularly to a bar automatic feeding device and its control method. Background Art

[0002] During the production process, bars usually need to be processed using numerically controlled machine tools. When feeding the bars into the numerically controlled machine tools, due to their long length and heavy weight, if manual feeding is adopted, multiple workers are required to assist in pushing. This method is time-consuming and laborious, and is also relatively prone to safety hazards. Therefore, bar automatic feeding devices have currently begun to be used for automatic feeding of bars.

[0003] In the prior art, when automatically feeding bars, most require the assistance of a manipulator, which has problems such as complex structure, difficult assembly, and high cost. Moreover, since there may be bar tailings remaining after bar processing, if the bar tailings are not promptly recycled, it may affect subsequent feeding, and even due to the residue of bar tailings, it may collide with the next bar to be fed, resulting in a jamming problem, thereby leading to low feeding efficiency and affecting the feeding quality. Summary of the Invention

[0004] The purpose of this application is to provide a bar automatic feeding device and its control method to improve the feeding efficiency and feeding quality.

[0005] In the first aspect, a bar automatic feeding device provided by this application adopts the following technical solution:

[0006] A bar automatic feeding device includes a frame, a feeding trough, a feeding mechanism, a clamping mechanism, a pushing mechanism, and a tailing recovery trough. The feeding trough is installed on the frame. The feeding mechanism is located on one side of the feeding trough. One end of the feeding trough is provided with a discharge port. The pushing mechanism is located at the end of the feeding trough far from the discharge port. The clamping mechanism is located between the pushing mechanism and the feeding trough. The tailing recovery trough is located below the clamping mechanism. A baffle assembly is provided above the feeding trough;

[0007] The feeding mechanism is used to feed bars into the feeding trough, and the clamping mechanism is used to clamp or release the bars located on the feeding trough;

[0008] The pushing mechanism includes a pushing component and a push rod. The push rod is used to insert into the bar and move along the feeding trough under the drive of the pushing component, so as to move the bar in the direction close to or away from the discharge port;

[0009] It further includes a driving mechanism and a controller. The driving mechanism and the pushing component are respectively communicatively connected to the controller. The driving mechanism is connected to the feeding mechanism, the baffle component and the clamping mechanism, and is used to drive the feeding mechanism to feed or stop, drive the baffle component to close or open, and drive the clamping component to clamp or release.

[0010] By adopting the above technical solution, in this application, a driving mechanism controls multiple different mechanisms of the feeding device, enabling them to cooperate with each other to automatically feed, clamp, and feed the bar, simplifying the equipment structure and reducing the assembly difficulty. At the same time, a tail stock recovery groove is provided to recover the bar tail stock after processing, so as to reduce the impact of the bar tail stock on subsequent feeding, and improve the feeding efficiency and quality of the feeding device.

[0011] Further, the feeding mechanism includes a plurality of feeding components and a feeding rack. The feeding rack is inclined and installed on one side of the feeding trough, and the plurality of feeding components are installed on the feeding rack;

[0012] The feeding component includes a support block and a material pushing block. The support block is fixedly connected to the feeding rack to form a feeding trough. The support block has a convex portion at one end of the feeding trough close to the feeding trough. The material pushing block is slidably connected to the support block, and is used to move towards the direction close to the feeding trough until it is flush with the convex portion to start feeding of the feeding mechanism, and move away from the feeding trough to stop feeding of the feeding mechanism.

[0013] By adopting the above technical solution, in this application, the material pushing block of the feeding component moves to lift the bar from the feeding rack and enter the feeding trough through the feeding trough, ensuring the reliability of the feeding process.

[0014] Further, the plurality of feeding components are connected by a rotatable first connecting rod, and a rotating connection block is provided at the connection between the first connecting rod and the feeding component;

[0015] One end of the rotating connection block is sleeved outside the first connecting rod, and the other end of the rotating connection block is connected to the end of the material pushing block far from the feeding trough. The first connecting rod is used to drive the material pushing block to move towards the direction close to the feeding trough when rotating clockwise, and drive the material pushing block to move away from the feeding trough when rotating counterclockwise.

[0016] By adopting the above technical solution, in this application, the first connecting rod synchronously drives the material pushing blocks of all feeding components to move, so as to synchronously feed and ensure the reliability of the feeding process.

[0017] Further, the baffle assembly includes a first baffle, several baffle connecting blocks, and a second connecting rod. The second connecting rod is rotatably installed on the side of the feeding trough away from the feeding mechanism. The several baffle connecting blocks connect the first baffle and the second connecting rod. The second connecting rod is used to make the first baffle approach the feeding trough when rotating clockwise and make the first baffle move away from the feeding trough when rotating counterclockwise.

[0018] By adopting the above technical solution, in the present application, the feeding trough is shielded and protected by the baffle assembly. The second connecting rod drives the first baffle to open and close. 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, protecting the feeding trough while ensuring the reliability of the feeding process.

[0019] Further, the clamping mechanism includes a clamping assembly. The clamping assembly includes two clamping members. The two clamping members are respectively located on both sides of the end of the feeding trough away from the discharge port. The two clamping members are used to make the clamping assembly clamp when approaching each other and loosen when moving away from each other.

[0020] By adopting the above technical solution, in the present application, the clamping members are controlled to approach or move 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 perform stable feeding, ensuring the reliability of the clamping and feeding processes.

[0021] Further, the clamping mechanism further includes a transmission assembly. The transmission assembly includes a moving block and two transmission plates. The two transmission plates are respectively located on both sides of the feeding trough. The middle of the transmission plate is rotatably fixed to the machine frame through a rotating shaft. A limiting groove is provided inside the transmission plate;

[0022] A limiting column is provided on the top of the moving block. The limiting column is used to abut against the limiting groove when the moving block moves in the direction away from the clamping assembly, so that the abutting part of the transmission plate and the limiting column rotates outward around the rotating shaft;

[0023] The two transmission plates are respectively connected to the outside of the two clamping members. The transmission plate is used to make the two clamping members approach each other when rotating inward around the rotating shaft and move away from each other when rotating outward around the rotating shaft.

[0024] By adopting the above technical solution, in the present application, the transmission plate rotates around the rotating shaft to drive the clamping members to approach or move away, simplifying the equipment structure and ensuring the reliability of the clamping process.

[0025] Further, the driving mechanism includes a motor, a first gear, a first rack, and a driving rod. The first gear is nested on the output shaft of the motor. The first gear meshes with the first rack. The first rack is installed on the upper surface of the driving rod. The end of the driving rod away from the motor passes through the clamping mechanism and is connected to the feeding mechanism. The motor is used to drive the driving rod to move towards or away from the feeding groove.

[0026] By adopting the above technical solution, the driving mechanism of the present application converts the rotation of the output shaft of the motor into the movement of the driving rod towards or away from the feeding groove through the cooperation of the first gear and the first rack, ensuring the stability of the driving.

[0027] Further, the moving block is installed on the upper surface of the driving rod. First inclined blocks and second inclined blocks are respectively arranged on both sides of the connection between the driving rod and the feeding mechanism;

[0028] The first connecting rod is nested with a first limiting block. The first limiting block abuts against the inclined surface of the first inclined block through a first cylinder. 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 groove under the drive of the driving rod;

[0029] The second connecting rod is nested with a second limiting block. The second limiting block abuts against the inclined surface of the second inclined block through a second cylinder. The second cylinder is used to move upward along the inclined surface of the second inclined block when the second inclined block moves away from the feeding groove under the drive of the driving rod.

[0030] By adopting the above technical solution, the present application can simultaneously drive the moving block, the first inclined block, and the second inclined block to move by moving the driving rod. The movement of the moving block can drive the clamping component to clamp or loosen. The movement of the first inclined block can drive the feeding mechanism to feed or stop. The movement of the second inclined block can drive the baffle component to close or open. The operation of multiple mechanisms can be controlled by one driving mechanism, further simplifying the equipment structure, reducing costs, and ensuring the stability and reliability of the feeding.

[0031] In the second aspect, a control method for the automatic bar feeding device provided by the present application adopts the following technical solution:

[0032] A control method for an automatic bar feeding device, applied to an automatic bar feeding device described in the first aspect, includes:

[0033] The starting position of the pushing mechanism is the rear origin position. When receiving an automatic feeding signal, the controller issues a forward rotation signal to the driving mechanism to make the driving mechanism drive the feeding mechanism to feed;

[0034] When receiving the signal indicating that the feeding is completed, the controller issues a reverse signal to the driving mechanism, causing the driving mechanism to drive the clamping mechanism to clamp the bar.

[0035] When receiving the signal indicating that the material clamping is completed, the controller controls the pushing component to drive the push rod to move towards the feeding chute, so that the push rod is inserted into the bar.

[0036] When receiving the signal indicating that the material insertion is completed, the controller controls the driving mechanism to drive the clamping mechanism to release the bar, and the controller issues a forward instruction to control the pushing mechanism to push the bar towards the discharging opening.

[0037] By adopting the above technical solution, the control method of the present application includes the control of the feeding process. When receiving the feeding signal, it means that the feeding process needs to be carried out currently. The controller can simultaneously control the feeding mechanism, the baffle component and the clamping mechanism through the driving mechanism to achieve feeding and material clamping, and then control the pushing component to drive the push rod to push the bar towards the discharging opening, so as to complete the feeding process, without manual operation, realizing automatic feeding, and ensuring the reliability of the feeding process, improving the feeding efficiency and quality.

[0038] Furthermore, it also includes:

[0039] When receiving the signal indicating that the processing is completed, the controller issues a backward instruction to control the pushing mechanism to move towards the rear origin position.

[0040] When the pushing mechanism moves to the rear origin position, the controller detects whether there is any residual bar material at present.

[0041] When there is residual bar material, the controller controls the driving mechanism to drive the clamping mechanism to clamp the residual bar material.

[0042] The controller controls the pushing component to drive the push rod to move away from the feeding chute, so that the push rod is pulled out of the residual bar material.

[0043] The controller controls the driving mechanism to drive the clamping mechanism to release the residual bar material, so that the residual bar material enters the residual material recovery tank.

[0044] By adopting the above technical solution, since the bar is processed outside the discharging opening after feeding, there may be residual bar material after the processing of the bar. When the present application receives the signal indicating that the processing is completed, that is, after the bar is processed, it detects whether there is any residual bar material at present. When there is residual bar material, a residual material recovery process is carried out to recover the residual bar material to the residual material recovery tank, so as to ensure that the subsequent feeding will not be affected by the existence of the residual material and improve the bar feeding quality.

[0045] In summary, the present application includes at least one of the following beneficial technical effects:

[0046] 1. This application controls multiple different mechanisms of the feeding device through a driving mechanism, enabling them to cooperate with each other for automatic feeding, clamping, and material feeding of the bar, simplifying the equipment structure, reducing the assembly difficulty, and at the same time setting up a tail material recovery tank to recover the bar tail material after processing, so as to reduce the influence of the bar tail material on subsequent feeding and improve the feeding efficiency and quality of the feeding device;

[0047] 2. This application shields and protects the feeding chute through a baffle component, 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 chute; when the baffle needs to be closed after the feeding process, the second connecting rod drives the first baffle close to the feeding chute, protecting the feeding chute while ensuring the reliability of the feeding process;

[0048] 3. This application controls the clamping piece to approach or move away to clamp or release the bar placed on the feeding chute. When clamping, it can cooperate with the pusher mechanism to insert the push rod into the bar; when releasing, it can enable the pusher mechanism to perform stable feeding, ensuring the reliability of the clamping and feeding processes;

[0049] 4. By moving the driving rod, the moving block, the first limiting block, and the second limiting block can be moved simultaneously. The movement of the moving block can drive the clamping component to clamp or release. The movement of the first limiting block can drive the feeding mechanism to feed or stop. The movement of the second limiting block can drive the baffle component to close or open. The operation of multiple mechanisms can be controlled through one driving mechanism, further simplifying the equipment structure, reducing costs, and ensuring the stability and reliability of feeding.

Detailed implementation manners

[0058] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 7 drawings, which will be described in further detail below.

[0059] When automatically feeding bars in the prior art, most of them require the assistance of a manipulator, which has problems of complex structure, difficult assembly and high cost. And because there may be bar tail stocks left after the processing of the bars, if the bar tail stocks are not recycled in time, it may affect the subsequent feeding, and even due to the residue of the bar tail stocks, it may collide with the next bar to be fed, resulting in a jamming problem, thus leading to low feeding efficiency and affecting the feeding quality. Therefore, the embodiment of the present application provides an automatic bar feeding device, referring to Figure 1 FIG. 1, which includes a frame 1, a feeding trough 2, a feeding mechanism 3, a clamping mechanism 4, a pushing mechanism 5 and a tail stock recovery trough 6. The feeding trough 2 is installed on the frame 1. The feeding mechanism 3 is located on one side of the feeding trough 2. One end of the feeding trough 2 is provided with a discharging opening 21. The pushing mechanism 5 is located at the end of the feeding trough 2 far from the discharging opening 21. The clamping mechanism 4 is located between the pushing mechanism 5 and the feeding trough 2. The tail stock recovery trough 6 is located below the clamping mechanism 4. A baffle assembly 22 is provided above the feeding trough 2.

[0060] It further includes a driving mechanism 7 and a controller 8. The driving mechanism 7 and the pushing mechanism are respectively in communication connection with the controller 8 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. The driving mechanism 7 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 loosen. In the specific implementation process, the controller 8 can adopt a PLC control system.

[0061] The implementation principle of the embodiments of this application is as follows: During the feeding process, the feeding mechanism 3 is used to store the rod to be fed and to feed the rod into the feeding groove 2 when feeding is required. The feeding groove 2 is used to place the rod. The clamping mechanism 4 is used to clamp one end of the rod and cooperate with the pushing mechanism 5. The pushing mechanism 5 is used to move the rod close to the discharge port 21. During the tail stock recovery process, the pushing mechanism 5 is used to move the rod tail stock away from the discharge port 21. The clamping mechanism 4 is used to clamp the rod tail stock and cooperate with the pushing mechanism 5 to make the rod tail stock fall into the tail stock recovery groove 6. The tail stock recovery groove 6 is used to store the rod tail stock after processing, so as to achieve fully automated feeding and tail stock recovery. A driving mechanism 7 is used to control multiple different mechanisms of the feeding device, enabling them to cooperate with each other to perform automated feeding, clamping, and discharging of the rod, simplifying the equipment structure, reducing the assembly difficulty. At the same time, the tail stock recovery groove 6 is provided to recover the rod tail stock after processing, so as to reduce the impact of the rod tail stock on subsequent feeding and improve the feeding efficiency and quality of the feeding device.

[0062] In the specific implementation process, the frame 1 serves as the basic support structure of the entire automatic feeding device. The frame 1 needs to be stable and reliable, capable of withstanding various forces and vibrations generated during the processing. The frame 1 is used to support components such as the feeding groove 2, the feeding mechanism 3, the clamping mechanism 4, the pushing mechanism 5, and the tail stock recovery groove. The feeding groove 2 is the channel for the rod to move from the feeding mechanism 3 to the processing area. Its design should ensure that the rod can be smoothly and continuously transported. The shape, size, and surface material of the feeding groove 2 need to be optimized according to the characteristics of the rod and the processing requirements to reduce friction and wear. The feeding mechanism 3 is used to introduce the rod to be processed from the outside into the feeding groove 2. It can include one or more sensors for detecting the arrival of the rod and triggering subsequent feeding actions. 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 rod 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 appropriate, which can both stably clamp the rod and not damage its surface. At the same time, the clamping mechanism 4 should also have the ability of quick response and accurate clamping to adapt to rods of different specifications and materials. The pushing mechanism 5 is used to push the rod from the feeding groove 2 to the processing area, and can achieve precise control of the pushing distance and speed. The pushing mechanism 5 should also have an overload protection function to prevent damage to the equipment due to rod jamming or excessive resistance during the pushing process. The tail stock recovery groove is used to collect the remaining rod tail stock after processing. These tail stocks may not be able to be used continuously due to insufficient length or processing defects, but waste can be reduced through recycling. The design of the tail stock recovery groove should be convenient for cleaning and maintenance and have a certain storage capacity to meet the processing requirements of different batches.

[0063] AsFigure 1 and Figure 2 As shown in Figure 2 , the feeding mechanism 3 includes a plurality of feeding components 31 and a feeding rack 32. The feeding rack 32 is inclined and installed on one side of the feeding chute 2. The plurality of feeding components 31 are installed on the feeding rack 32, and the feeding rack 32 is used for storing the bars to be fed. The feeding component 31 includes a support block 311 and a pusher block 312. The support block 311 is fixedly connected to the feeding rack 32 to form a feeding chute. The support block 311 has a protruding portion 313 at one end of the feeding chute close to the feeding chute 2. The pusher block 312 is slidably connected to the support block 311. The pusher block 312 is used to move towards the feeding chute direction until it is flush with the protruding portion 313 to start the feeding of the feeding mechanism 3, and move away from the feeding chute direction to stop the feeding of the feeding mechanism 3. The plurality of feeding components 31 are connected by a rotatable first connecting rod 33, and 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 connecting block 331 is sleeved outside the first connecting rod 33, and the other end of the rotating connecting block 331 is connected to one end of the pusher block 312 away from the feeding chute. The first connecting rod 33 is used to drive the pusher block 312 to move towards the feeding chute direction when rotating clockwise, and drive the pusher block 312 to move away from the feeding chute direction when rotating counterclockwise. In the specific implementation process, the rotation direction is the clockwise rotation and counterclockwise rotation as viewed from the discharge port 21 towards the pushing mechanism 5.

[0064] When no feeding is required, the bars to be fed are stored on the feeding rack 32. Due to the limiting effect of the protruding portion 313, the bars are fixed on the feeding rack 32 and will not slide down. When feeding is required, the driving mechanism 7 controls the first connecting rod 33 to rotate clockwise, driving the pusher block 312 to move towards the feeding chute direction, lifting the bars towards the feeding chute 2. When the top of the pusher block 312 moves to be flush with the protruding portion 313, the limiting effect of the protruding portion 313 disappears. Due to the inclination angle of the feeding rack 32, the bars move down along the feeding chute to the feeding chute 2, thus realizing the feeding process.

[0065] As Figure 1 and Figure 2 shown in Figure 2 , the baffle component 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 installed on the side of the feeding chute 2 away from the feeding mechanism 3. The plurality of baffle connecting blocks 222 connect the first baffle 221 and the second connecting rod 223. The second connecting rod 223 is used to make the first baffle 221 close to the feeding chute 2 when rotating clockwise, and make the first baffle 221 away from the feeding chute 2 when rotating counterclockwise. In the specific implementation process, the rotation direction is the clockwise rotation and counterclockwise rotation as viewed from the discharge port 21 towards the pushing mechanism 5.

[0066] When no feeding is required, the control mechanism controls the second connecting rod 223 to rotate clockwise, driving the first baffle 221 to approach the feeding groove 2, closing the first baffle 221, and shielding and protecting the feeding groove 2. When feeding is required, the control mechanism controls the second connecting rod 223 to rotate counterclockwise, driving the first baffle 221 away from the feeding groove 2, opening the first baffle 221, and facilitating the bar to enter the feeding groove 2 through the feeding chute.

[0067] As Figure 1 and Figure 3 shown, the clamping mechanism 4 includes a clamping component 41 and a transmission component 42. The clamping component 41 includes two clamping members 411. The two clamping members 411 are respectively located on both sides of one end of the feeding groove 2 away from the discharge port 21. The clamping members 411 are fixedly connected to the machine frame 1 through springs. The two clamping members 411 are used to clamp the clamping component 41 when approaching each other and loosen the clamping component 41 when moving away from each other. The transmission component 42 includes a moving block 421 and two transmission plates 422. The two transmission plates 422 are respectively located on both sides of the feeding groove 2. The middle of the transmission plate 422 is rotatably fixed to the machine frame 1 through a rotating shaft. A limiting groove 4221 is provided inside 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 component 41, causing the contact point between the transmission plate 422 and the limiting column 4211 to rotate outward around the rotating shaft. The two transmission plates 422 are respectively connected to the outside of the two clamping members 411. The transmission plate 422 is used to make the two clamping members 411 approach each other when rotating inward around the rotating shaft and move away from each other when rotating outward around the rotating shaft.

[0068] When no clamping is required, due to the elastic force of the spring, the two clamping members 411 maintain a separated state, loosening the clamping component 41. The moving block 421 approaches the clamping component 41, and the two transmission plates 422 maintain their initial states, with the limiting column 4211 and the limiting groove 4221 remaining non-contact. When clamping is required, the moving block 421 moves away from the clamping component 41, causing the limiting column 4211 to approach the limiting groove 4221 until they abut. Under the limiting effect 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 of the transmission plate 422 is fixed by the rotating shaft, the end of the transmission plate 422 connected to the clamping member 411 moves inward, causing the clamping member 411 to move inward, so that the two clamping members 411 approach each other, clamping the clamping component 41, and thus realizing the clamping process.

[0069] As Figure 1 、 Figure 3 and Figure 4As shown in the figure, 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 on the output shaft of the motor 71. The first gear 72 meshes with the first rack 73. The first rack 73 is installed on the upper surface of the driving rod 74. One 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. The motor 71 is used to drive the driving rod 74 to move towards or away from the feeding groove 2. The moving block 421 of the transmission component 42 is installed on the upper surface of the middle part of the driving rod 74. On both sides of the connection between the driving rod 74 and the feeding mechanism 3, there are respectively a first inclined block 741 and a second inclined block 742. By moving the driving rod 74, the moving block 421, the first inclined block 741 and the second inclined block 742 can be moved simultaneously. The movement of the moving block 421 can drive the clamping component 41 to clamp or loosen. The movement of the first inclined block 741 can drive the feeding mechanism 3 to feed or stop. The movement of the second inclined block 742 can drive the baffle component 22 to close or open. In the specific implementation process, the motor 71 adopts a reduction motor.

[0070] As Figure 1 and Figure 4 shown in the figure, the first connecting rod 33 is nested with a first limiting block 743. The first limiting block 743 abuts against the inclined surface of the first inclined block 741 through a 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 groove 2 under the drive of the driving rod 74. In the specific implementation process, when the driving rod 74 moves away from the feeding groove 2, the first inclined block 741 synchronously moves away from the discharge port 21. The first cylinder 744 then moves obliquely upward towards the discharge port 21 along the inclined surface of the first inclined block 741. Since the first limiting block 743 is nested 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, and making the ejector block 312 move away from the feeding groove, restricting the feeding of the bar placed on the feeding rack 32. When the driving rod 74 moves towards the feeding groove 2, the first inclined block 741 synchronously moves towards the discharge port 21. The first cylinder 744 then moves obliquely downward away from the discharge port 21 along the inclined surface of the first inclined block 741. Since the first limiting block 743 is nested outside the first connecting rod 33, it drives the first limiting block 743 to move obliquely downward, thereby driving the first connecting rod 33 to rotate clockwise, and making the ejector block 312 move towards the feeding groove, pushing the bar placed on the feeding rack 32 to the feeding groove 2, completing the process of controlling the feeding component 31 to feed through the driving mechanism 7.

[0071] As Figure 1 and Figure 4As shown, the second connecting rod 223 is embedded with a second limiting block 745, and the second limiting block 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 feed chute 2 under the drive rod 74. In a specific implementation, when the drive rod 74 moves away from the feed chute 2, the second inclined block 742 simultaneously moves away from the discharge port 21, and the second cylinder 746 moves along the inclined surface of the second inclined block 742 toward the upper oblique direction close to the discharge port 21. Since the second limiting block 745 is embedded outside the second connecting rod 223, it drives the second limiting block 745 to move obliquely upward, thereby driving the first connecting rod 33 to rotate clockwise, causing the baffle connecting block 222 to rotate toward the feed chute 2, thereby closing the first baffle 221. When the driving rod 74 moves toward the direction closer to the feed trough 2, the second inclined block 742 moves synchronously toward the direction closer 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 toward the direction away from the feed trough 2, thereby opening the first baffle 221 and completing the process of controlling the opening and closing of the baffle assembly 22 through the driving mechanism 7.

[0072] In practice, the first and second inclined blocks 741, 742 have different inclinations. The specific inclinations are determined based on the required travel distance of the ejection block 312 and the required opening degree of the first baffle 221, i.e., the required rotation amplitude of the first and second connecting rods 33, 223. During the feeding process, by moving the drive rod 74 toward the feed trough 2, the feed assembly 31 can be simultaneously started, the baffle assembly 22 can be opened, and the clamping assembly 41 can be released, thereby facilitating the stable entry of the bar into the feed trough 2.

[0073] like Figure 1 and Figure 5 As shown, the pushing mechanism 5 includes a pushing assembly 51 and a push rod 52. The push rod 52 is used to be inserted into the bar and, driven by the pushing assembly 51, moves along the feed chute 2, causing the bar to move 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 meshes with the second gear 511. The push rod 52 is fixedly connected to the second rack 512. Driven by the second gear 511, the second rack 512 drives the push rod 52 to move toward or away from the discharge port 21.

[0074] In the specific implementation process, after the bar has been placed on the feeding chute 2 through the feeding mechanism 3, the clamping mechanism 4 is driven by the driving mechanism 7 to clamp one end of the bar close to the pushing mechanism 5. The pushing component 51 drives the push rod 52 close to the bar, so that the push rod 52 is inserted into the bar. Then, the clamping mechanism 4 is driven by the driving mechanism 7 to release the bar, and the push rod 52 pushes the bar to move towards the discharge port 21, thus realizing the feeding process. When the processing of the bar 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 it is detected that there is bar tail material, the driving mechanism 7 drives the clamping mechanism 4 to clamp the bar tail material, 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 of the bar tail material. The driving mechanism 7 drives the clamping mechanism 4 to release the bar tail material, and the bar tail material falls into the tail material recovery tank 6 below the clamping mechanism 4, thus realizing the tail material recovery process.

[0075] In the specific implementation process, the bottom of the tail material recovery tank 6 is of a pull-out structure. After a certain number of bar tail materials are recovered, the bar tail materials in the tail material recovery tank 6 can be further recovered by pulling out the pull-out structure.

[0076] In the preferred implementation mode, the discharge port 21 of the embodiment of the present application is provided with a telescopic sleeve, and the telescopic sleeve can ensure that the bar sent out from the discharge port 21 can accurately enter the external processing equipment. The bottom of the rack 1 is of a telescopic structure, and the height of the rack 1 can be correspondingly adjusted according to the height of the external processing equipment to ensure that the discharge port 21 can be aligned with the external processing equipment.

[0077] The embodiment of the present application also provides a control method for the bar automatic feeding device, which is applied to a bar automatic feeding device. Refer to Figure 6 , and the control method includes a feeding process:

[0078] S1. The starting position of the pushing mechanism 5 is the rear origin position. When receiving the automatic feeding signal, the controller 8 issues a forward rotation signal to the driving mechanism 7, so that the driving mechanism 7 drives the feeding mechanism to feed.

[0079] Specifically, the rear origin position is the starting position of the pushing mechanism 5, that is, the position away from the discharge port direction. The automatic feeding signal can be generated by the staff operating the touch device or the control button, or can be automatically generated by the external processing equipment and sent to the controller 8. When the controller 8 receives the feeding signal, the feeding process starts. The controller 8 can adopt a PLC control system, and the driving mechanism 7 can adopt a servo motor or a reduction motor, so as to receive the forward rotation signal and the reverse rotation signal issued by the controller 8.

[0080] S2. When receiving the signal indicating that the feeding is completed, the controller 8 issues a reverse signal to the driving mechanism 7, causing the driving mechanism 7 to drive the clamping mechanism 4 to clamp the bar.

[0081] Specifically, an induction device is provided on the feeding chute 2. When the induction device senses that the bar has been placed on the feeding chute 2, it generates and sends a signal indicating that the feeding is completed to the controller 8. When the controller 8 receives this signal, it starts the process of clamping the material.

[0082] S3. When receiving the signal indicating that the material clamping is completed, the controller 8 controls the pushing component 51 to drive the push rod 52 to move towards the feeding chute 2, so that the push rod 52 is inserted into the bar.

[0083] Specifically, after the process of clamping the material is completed, the controller 8 controls the cooperation of the pushing mechanism 5 and the clamping mechanism 4 to insert the push rod 52 into the interior of the bar.

[0084] S4. When receiving the signal indicating that the material insertion is completed, the controller 8 controls the driving mechanism 7 to drive the clamping mechanism 4 to release the bar, and the controller 8 issues a forward command to control the pushing mechanism 5 to push the bar towards the discharge port 21.

[0085] Specifically, the clamping mechanism 4 is controlled to release so that the pushing mechanism 5 can push the bar towards the discharge port 21, and the bar is discharged from the discharge port 21, thus completing the feeding process.

[0086] As Figure 7 shown, the control method of the embodiment of the present application further includes a process for recovering the remaining material:

[0087] S5. When receiving the signal indicating that the processing is completed, the controller 8 issues a backward command to control the pushing mechanism 5 to move towards the rear origin position.

[0088] Specifically, after the external processing equipment finishes processing the bar, it generates a signal indicating that the processing is completed and sends it to the controller 8. When the controller 8 receives this signal, it can control the pushing mechanism 5 to return to the initial position, that is, the rear origin position.

[0089] S6. When the pushing mechanism 5 moves to the rear origin position, the controller 8 detects whether there is any remaining bar material at present.

[0090] Specifically, an induction device can be provided on the surface of the middle part of the clamping mechanism 4 close to the feeding chute 2. The induction device senses whether there is any remaining bar material on the current push rod 52.

[0091] S7. When there is remaining bar material, the controller 8 controls the driving mechanism 7 to drive the clamping mechanism 4 to clamp the remaining bar material.

[0092] Specifically, if there is bar stock tail material, the induction device generates a tail material recovery signal. When the controller 8 receives the tail material recovery signal, it automatically starts the tail material recovery process.

[0093] S8. The controller 8 controls the pushing component 51 to drive the push rod 52 to move away from the feeding chute 2, so as to pull out the push rod 52 from the bar stock tail material.

[0094] S9. The controller 8 controls the driving mechanism 7 to drive the clamping mechanism 4 to release the bar stock tail material, so that the bar stock tail material enters the tail material recovery chute 6.

[0095] Specifically, through the mutual cooperation of the clamping mechanism 4 and the pushing mechanism, the bar stock tail material is pulled out from the push rod 52 and falls into the tail material recovery chute 6 below the clamping mechanism 4, thus completing the tail material recovery process.

[0096] In the specific implementation process, the control method of the bar automatic feeding device in the embodiment of the present application is usually implemented based on a PLC (programmable logic controller) or other automation control systems. The core of the control method is to realize the coordinated work between components and ensure the continuity and stability of the entire feeding process. The specific functions include: startup. After the power is turned on, the system enters the standby state and waits for an external startup signal. Feeding detection. The sensor detects whether there is bar stock in the feeding chute 2. If it is in place, the feeding action is triggered. Clamping and pushing. After the clamping mechanism 4 clamps the bar stock, the pushing mechanism 5 starts to push the bar stock to the processing area. Processing monitoring. During the processing, the control system continuously monitors the operating status of each component to ensure that there is no abnormality. Tail material recovery. After the processing is completed, the remaining tail material is sent to the tail material recovery chute for collection. Circulation and stop. According to the production requirements, the system automatically enters the next working cycle or stops working.

[0097] The implementation principle of the embodiment of the present application is: by integrating key components such as the integrated rack 1, the feeding chute 2, the feeding mechanism 3, the clamping mechanism 4, the pushing mechanism 5 and the tail material recovery chute, and adopting advanced automation control technology, the functions of automatic feeding and tail material recovery in the bar processing process are realized, and the production efficiency and resource utilization rate are improved.

The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
