Description

Technical Field

[0001] The invention relates to the field of feeding equipment, in particular to an automatic material distribution and conveying system and an automatic material distribution and conveying method. Background Art

[0002] Rods or tubes are materials that are frequently used in industrial production. Rods or tubes are usually delivered to the production site in the form of long workpieces, and then cut to length by cutting equipment according to the length of the rods or tubes required for production. During the cutting process, the long workpieces need to be transported. In order to improve the feeding efficiency and feeding accuracy, as well as to reduce labor costs, many companies currently use automatic material distribution and conveying devices to feed the long workpieces one by one into the cutting equipment for fixed-length cutting.

[0003] For example, Chinese utility model patent CN216097767U discloses an automatic feeding device for a lathe, which includes a storage rack and a feeding rack, the storage rack is connected to the feeding rack, a material stopper assembly which can be extended up and down is arranged at the connection between the storage rack and the feeding rack, and a stopping mechanism which can slide along the feeding rack and a material picking assembly which plays a lifting role is arranged at one end of the feeding rack away from the storage rack, and the stopping mechanism and the material picking assembly are arranged side by side and correspond to each other; when feeding is required, the position of the stopping baffle in the stopping mechanism is adjusted according to the thickness of the anchor bolt, and then the material stopper assembly retracts downward, and the workpiece on the storage rack rolls along the feeding rack and stops moving when rolling to the stopping baffle, and then the material picking cylinder of the material picking assembly pushes upward, drives the material picking plate to move upward, picks the anchor bolt out of the stopping baffle, and transfers it to the subsequent processing device to complete the feeding operation.

[0004] However, the above-mentioned automatic feeding device is not suitable for conveying large-diameter long workpieces with a diameter of more than 200mm. The weight of a large-diameter long workpiece reaches more than 4 tons. When several large-diameter long workpieces roll along the feeding rack to the position of the stop baffle, a large impact force will be generated on the stop baffle and even the entire stop mechanism, which may easily cause damage to the entire stop mechanism; and when several large-diameter long workpieces stay on the feeding rack, since the feeding rack is inclined, several large-diameter long workpieces have a tendency to roll toward the stop baffle, thereby squeezing several large-diameter long workpieces together. When the picking component lifts a certain large-diameter long workpiece, in addition to overcoming the gravity of the large-diameter long workpiece itself, it is also necessary to overcome the squeezing friction of other large-diameter long workpieces on the large-diameter long workpiece, making the lifting difficult and easily causing damage to the picking component.

[0005] In addition, in order to ensure that the cutting surface is a vertical plane, the top surface of the feeding device in the prior art is maintained on the same horizontal plane as the top surface of the cutting platform of the cutting device. However, since long workpieces may bend during the production and transportation process, the bottom surface of the end of the long workpiece may be lower than the workpiece-bearing surface of the cutting platform during the transportation process, making it impossible for the end of the long workpiece to enter the cutting platform smoothly, and automatic feeding cannot be achieved.

[0006] Based on this, it is necessary to provide a technical solution to solve the above problems. Summary of the invention

[0011] Furthermore, the third driving mechanism includes a first cylinder and a sliding rod connected to the output end of the first cylinder, a rack is provided on the sliding rod corresponding to the position of each eccentric conveying roller mechanism, and a gear meshing with the corresponding rack is fixed at one end of each eccentric conveying roller mechanism.

[0012] Furthermore, a material pressing and conveying mechanism is also provided at one end of the discharge side of the frame, and the material pressing and conveying mechanism includes an active conveying roller, and a rotating drive mechanism and a lifting drive mechanism driven and connected to the active conveying roller, and the active conveying roller is arranged above the eccentric conveying roller mechanism.

[0017] On the other hand, the present invention also provides an automatic material distribution and conveying method, which is performed by using the automatic material distribution and conveying system described in any of the above embodiments, and the method comprises the following steps:

[0018] S1: A plurality of long workpieces are carried on the first horizontal section of the carrying rod, wherein the long workpiece closest to the discharge side is the first long workpiece, the control mechanism starts the feeding program, the third driving mechanism drives the eccentric conveying roller mechanism to rotate, thereby driving the second baffle rod to swing downward to the avoidance position, and at the same time the second driving mechanism drives the first baffle rod to rotate and lift;

[0019] S2: the first driving mechanism drives the lifting rod to rotate and lift, so that an angle is formed between the lifting rod and the first blocking rod, and a plurality of the long workpieces move along the lifting rod toward the discharge side during the process of the lifting rod rotating and lifting;

[0020] S3: When the first long workpiece moves to the angle position, the sensor detects the first long workpiece and feeds back the detection signal to the control mechanism, and the control mechanism controls the first driving mechanism to drive the lifting rod to rotate and lower. When the lifting rod rotates to the initial position, the first long workpiece is carried between the blocking block and the first blocking rod, and the remaining long workpieces are re-carried on the carrying rod and are located on the inclined section or the first horizontal section. The long workpiece located on the inclined section falls back to the first horizontal section along the inclined section due to gravity.

[0021] S4: the third driving mechanism drives the eccentric conveying roller mechanism to rotate, thereby driving the second baffle rod to swing upward to the material blocking position. At this time, the horizontal height of the top of the eccentric conveying roller mechanism is higher than the horizontal height of the second horizontal section. Then the second driving mechanism drives the first baffle rod to rotate and lower. At the same time, the first long workpiece is lowered to the top of the multiple eccentric conveying roller mechanisms during the process of the first baffle rod rotating and lowering.

[0022] S5: The first long workpiece is transported to the next processing station along the eccentric conveying roller mechanism, completing the automatic material division and transportation of a long workpiece.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) A lifting rod and a first baffle are provided, and one end of the lifting rod close to the discharging side and the other end of the first baffle away from the discharging side are respectively hingedly connected to the frame. When feeding is required, the second driving mechanism drives the first baffle to rotate and lift, and the first driving mechanism drives the lifting rod to rotate and lift. During the lifting of the lifting rod, the lifting rod is higher than the load-bearing rod, and the lifting rod lifts a plurality of long workpieces from the first horizontal section. At this time, the lifting rod is inclined, and the plurality of long workpieces move along the lifting rod toward the discharging side under the action of gravity. Since the inclination directions of the lifting rod and the first baffle are opposite, an angle is formed between the lifting rod and the first baffle, and the movement of the plurality of long workpieces is limited at the angle position, without the need to adopt a stopping mechanism such as a stop baffle, thereby avoiding the situation in the prior art where a stop baffle is used to block and limit the rolling large-diameter long workpiece, thereby causing the large-diameter long workpiece to generate a large impact force on the stop baffle, thereby easily causing damage to the stop baffle;

[0025] (2) By setting a material stop block, when the sensor detects the first long workpiece and feeds back the detection signal to the control mechanism, the control mechanism controls the first driving mechanism to drive the lifting rod to rotate and lower, because the position of the angle vertex is located on the side of the material stop block close to the discharge side, the bottom of the first long workpiece is supported between the material stop block and the first stop rod, that is, the material stop block and the first stop rod limit the first long workpiece, and the remaining long workpieces are re-supported on the supporting rod and are located on the inclined section or the first horizontal section. The long workpiece located on the inclined section falls back to the first horizontal section along the inclined section due to gravity, that is, the separation between the first long workpiece and the remaining long workpieces is achieved, and there is no need to use a lifting mechanism, which avoids the need to overcome the squeezing friction of other long workpieces on the lifted long workpiece during the lifting and separation process, thereby making the lifting difficult and easily causing damage to the lifting mechanism;

[0026] (3) By setting an eccentric conveying roller mechanism and a second baffle, the third driving mechanism drives the eccentric conveying roller mechanism to rotate, thereby driving the second baffle to swing between the avoidance position and the material blocking position. When the second baffle is located at the material blocking position, the top of the roller is at the highest position, and when the second baffle is located at the avoidance position, the top of the roller is at the lowest position. By matching the position of the second baffle with the horizontal height of the top of the roller, when a number of long workpieces roll from the feed side to the discharge side, the second baffle is located at the avoidance position and the top of the roller is at the lowest position, thereby preventing the second baffle from blocking the movement of the long workpiece and preventing the rolling long workpiece from colliding with the roller. When the first long workpiece is separated, the second baffle is located at the material blocking position and the top of the roller is at the highest position. On the one hand, the first long workpiece is accurately positioned by the second baffle, and on the other hand, it is convenient for the first long workpiece to be carried on the top of the roller so that the bottom surface of the long workpiece is higher than the horizontal height of the workpiece bearing surface of the cutting platform, and even if the long workpiece is bent, its end can be ensured to enter the cutting platform smoothly.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0036] Example 1

[0037] like Figures 1 to 6As shown, embodiment 1 provides an automatic material distribution and conveying system, including a control mechanism and a frame 1, wherein the two sides of the frame are respectively a feed side 11 and a discharge side 12, a plurality of bearing rods 2 and a plurality of lifting rods 3 are arranged at intervals along the length direction on the frame 1, a plurality of first baffle rods 4, a plurality of eccentric conveying roller mechanisms 5 and at least one sensor are arranged at intervals along the length direction on the discharge side 12 of the frame 1; one end of the lifting rod 3 close to the discharge side 12 and the end of the first baffle rod 4 away from the discharge side 12 are respectively hingedly connected to the frame 1; a plurality of the lifting rods 3 are connected to a first driving mechanism 30, and the first driving mechanism 30 is used to drive the plurality of the lifting rods 3 to rotate around their hinged positions; a plurality of the first baffle rods 4 are connected to It is connected to a second driving mechanism 40, which is used to drive multiple first baffle bars 4 to rotate around their hinged positions; each of the eccentric conveying roller mechanisms 5 is fixedly provided with a second baffle bar 6 at one end close to the feed side 11, and multiple eccentric conveying roller mechanisms 5 are connected to a third driving mechanism 50, and the third driving mechanism 50 is used to drive the eccentric conveying roller mechanisms 5 to rotate so as to drive the second baffle bar 6 to swing between the avoidance position and the blocking position; along the direction from the feed side 11 to the discharge side 12, the bearing rod 2 sequentially includes a first horizontal section 21, an inclined section 22 and a second horizontal section 23, and the horizontal height of the second horizontal section 23 is higher than the horizontal height of the first horizontal section 21, and a baffle block 24 is provided at one end of the second horizontal section 23 close to the inclined section 22.

[0038] Specifically, the supporting rod 2 is fixedly connected to the frame 1; when the first driving mechanism 30 and the second driving mechanism 40 are not in action, the lifting rod 3 and the first baffle rod 4 are in the initial position. At this time, the lifting rod 3 and the first baffle rod 4 are both horizontally arranged, and the horizontal height of the top of the lifting rod 3 is less than or equal to the horizontal height of the top of the first horizontal section 21, and the horizontal height of the top of the first baffle rod 4 is less than or equal to the horizontal height of the top of the second horizontal section 23; when the third driving mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby driving the second baffle rod 6 to move to the avoidance position, at this time, the second baffle rod 6 is horizontally arranged and the top of the eccentric conveying roller mechanism 5 is at the lowest position, and the second baffle rod 6 will not block the movement of the long workpiece. When the third driving mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby driving the second baffle rod 6 to move to the blocking position, at this time, the second baffle rod 6 is vertically arranged and the top of the eccentric conveying roller mechanism 5 is at the highest position, the second baffle rod 6 will block the movement of the long workpiece and the horizontal height of the top of the eccentric conveying roller mechanism 5 is higher than the horizontal height of the top of the second horizontal section 23.

[0039] In actual use, a number of long workpieces are placed on the first horizontal section 21 of the carrying rod 2 through an external loading mechanism or manually, and the control mechanism starts the feeding program. First, the third driving mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby driving the second baffle rod 6 to swing downward to the avoidance position to prevent the second baffle rod 6 from blocking the movement of the long workpiece. At the same time, the second driving mechanism 40 drives the first baffle rod 4 to rotate and lift, and the movement of the long workpiece is limited by the first baffle rod 4; then, the first driving mechanism 30 drives the lifting rod 3 to rotate and lift Since the lifting rod 3 and the first stopper 4 are inclined in opposite directions, an angle is formed between the lifting rod 3 and the first stopper 4, and the vertex of the angle is located on the side of the stopper block 24 close to the discharge side 12. During the lifting of the lifting rod 3, the lifting rod 3 is higher than the bearing rod 2, and the lifting rod 3 lifts a plurality of long workpieces from the first horizontal section 21. Since the lifting rod 3 is inclined at this time, the plurality of long workpieces move toward the discharge side 12 along the lifting rod 3 under the action of gravity. Then, when the one closest to the discharge side When a long workpiece (defined as the first long workpiece) moves to the angle position, since the inclination direction of the first blocking rod 4 is opposite to the inclination direction of the lifting rod 3, the first long workpiece will stay at the angle position. At this time, the first long workpiece is carried at the angle position, that is, the horizontal height of the bottom of the first long workpiece is higher than the horizontal height of the top of the bearing rod 2 and the eccentric conveying roller mechanism 5. Therefore, when several long materials move toward the discharge side 12, they will not collide with the bearing rod 2 and the eccentric conveying roller mechanism 5, preventing the bearing The carrying rod 2 and the eccentric conveying roller mechanism 5 are damaged; at this time, due to the blocking effect of the first long workpiece, the remaining long workpieces also stop moving forward, that is, the lifting rod 3 and the first blocking rod 4 are tilted in opposite directions to form an angle to limit the movement of several long workpieces, without the need to use a stopping mechanism such as a stopping baffle, thereby avoiding the use of a stopping baffle in the prior art to block and limit the rolling large-diameter long workpiece, so that the large-diameter long workpiece generates a large impact force on the stopping baffle, which is easy to cause the stopping baffle to be damaged;Next, the sensor detects the first long workpiece and feeds back the detection signal to the control mechanism, which controls the first driving mechanism 30 to drive the lifting rod 3 to rotate and lower. When the lifting rod 3 rotates to the initial position, the lifting rod 3 is horizontally set and the horizontal height of the top of the lifting rod 3 is less than or equal to the horizontal height of the top of the first horizontal section 21. Since the position of the vertex of the angle is located on the side of the stop block 24 close to the discharge side 12, the bottom of the first long workpiece is supported between the stop block 24 and the first stop rod 4, that is, the stop block 24 and the first stop rod 4 limit the first long workpiece, and the remaining long workpieces are re-supported on the supporting rod 2 and are located on the inclined section 22 or the first horizontal section 21, located on the inclined The long workpiece on the inclined section 22 falls back to the first horizontal section 21 along the inclined section 22 due to the effect of gravity, thereby realizing the separation between the first long workpiece and the remaining long workpieces, without the need to use a lifting mechanism, thereby avoiding the need to overcome the squeezing friction of other long workpieces on the lifted long workpiece during the lifting and separation process, thereby causing great difficulty in lifting and easy damage to the lifting mechanism; then, the third driving mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby driving the second baffle rod 6 to swing upward to the material blocking position. At this time, the horizontal height of the top of the eccentric conveying roller mechanism 5 is higher than the horizontal height of the second horizontal section 23, and the position of the first long workpiece is precisely positioned by the second baffle rod 6 to ensure The position accuracy of the first long workpiece in the subsequent conveying process is improved; then, the second driving mechanism 40 drives the first baffle bar 4 to rotate and lower, and the first long workpiece drops to the top of multiple eccentric conveying roller mechanisms 5 during the process of the first baffle bar rotating and lowering; finally, the first long workpiece is conveyed to the next processing station along the eccentric conveying roller mechanism 5, thereby completing the automatic material delivery of a long workpiece; specifically, the next processing station is a cutting station. In order to avoid the situation where the end of the long workpiece cannot smoothly enter the cutting platform due to bending, the horizontal height of the workpiece bearing surface of the cutting platform is lower than the horizontal height when the top of the eccentric conveying roller mechanism 5 is in the highest position. The workpiece is carried on the eccentric conveying roller mechanism 5, so that the horizontal height of the bottom surface of the long workpiece is higher than the horizontal height of the workpiece bearing surface of the cutting platform. Even if the long workpiece is bent, its end can be ensured to smoothly enter the cutting platform, and the horizontal height of the workpiece bearing surface of the cutting platform is higher than or equal to the horizontal height when the top of the eccentric conveying roller mechanism 5 is at the lowest position. When the end of the long workpiece smoothly enters the cutting platform, the third driving mechanism 50 is controlled to drive the eccentric conveying roller mechanism 5 to rotate, so that the horizontal height of the top of the eccentric conveying roller mechanism 5 is reduced to the same as the horizontal height of the workpiece bearing surface of the cutting platform, thereby ensuring that the cutting surface formed on the long workpiece in the subsequent cutting process is a vertical plane. ;

[0040] More specifically, the eccentric conveying roller mechanism 5 comprises a rotating shaft 51, two supporting seats 52, two eccentric bearings 53 and a roller 54. The two supporting seats 52 are arranged at intervals on the discharge side 12 of the frame 1. The two ends of the rotating shaft 51 are respectively rotatably arranged in the two supporting seats 52, and one end of the rotating shaft 51 passes through the corresponding supporting seats 52 and is drivingly connected to the third driving mechanism 50. The two eccentric bearings 53 are fixedly arranged on the rotating shaft 51 and located between the two supporting seats 52. The two ends of the roller 54 are respectively sleeved on the two eccentric bearings 53. In this embodiment, on the one hand, the rotating shaft 51 is driven by the third driving mechanism 50 to rotate so as to adjust the position of the eccentric bearings 53, so as to adjust the horizontal height of the top of the eccentric conveying roller mechanism 5. On the other hand, the two ends of the roller 54 are sleeved on the eccentric bearings 53. When the long workpiece is conveyed to the next processing station, the roller 54 rotates with the long workpiece, effectively reducing the friction resistance during the conveying of the long workpiece.

[0041] More specifically, the second baffle 6 is fixedly connected to one end of the rotating shaft 51 close to the feeding side 11 and is located between the roller 54 and the supporting seat 52; when the second baffle 6 is located at the material blocking position, the top of the roller 54 is at the highest position, and when the second baffle 6 is located at the avoidance position, the top of the roller 54 is at the lowest position. Specifically, a connecting through hole is provided at one end of the rotating shaft 51 close to the feeding side 11, and the second baffle 6 is inserted into the connecting through hole. In this embodiment, the position of the second baffle rod 6 is matched with the horizontal height of the top of the roller 54. When a plurality of long workpieces roll from the feed side to the discharge side, the second baffle rod 6 is located in the avoidance position and the top of the roller 54 is at the lowest position, preventing the second baffle rod 6 from blocking the movement of the long workpiece and preventing the rolling long workpiece from colliding with the roller 54; when the first long workpiece is separated, the second baffle rod 6 is located in the blocking position and the top of the roller 54 is at the highest position. On the one hand, the first long workpiece is accurately positioned by the second baffle rod 6, and on the other hand, it is convenient for the first long workpiece to be supported on the top of the roller 54 so that the bottom surface of the long workpiece is higher than the horizontal height of the workpiece supporting surface of the cutting platform. Even if the long workpiece is bent, its end can be ensured to enter the cutting platform smoothly.

[0042] More specifically, the third driving mechanism 50 includes a first cylinder 501, a slide bar 502 connected to the output end of the first cylinder 501, a rack 503 is provided on the slide bar 502 at a position corresponding to each of the eccentric conveying roller mechanisms 5, and a gear 504 meshing with the corresponding rack 503 is fixed at one end of each of the eccentric conveying roller mechanisms 5. In this embodiment, only one first cylinder 501 is required to drive multiple eccentric conveying roller mechanisms 5 to rotate synchronously, which has a simple structure and low cost.

[0043] More specifically, a material pressing and conveying mechanism 8 is further provided at one end of the material discharging side 12 of the frame 1, and the material pressing and conveying mechanism 8 includes an active conveying roller 81, and a rotating drive mechanism and a lifting drive mechanism 82 drivingly connected to the active conveying roller 81, and the active conveying roller 81 is arranged above the eccentric conveying roller mechanism 5. Specifically, a fixed frame 83 is also included, and the active conveying roller 81, the rotating drive mechanism, and the lifting drive mechanism 82 are all arranged on the fixed frame 83. In this embodiment, when the first long material workpiece descends to the top of the multiple eccentric conveying roller mechanisms 5 during the process of the first baffle 4 rotating and lowering, the lifting drive mechanism 82 drives the active conveying roller 81 to press down to the top of the first long material workpiece, and the rotating drive mechanism drives the active conveying roller 81 to rotate, thereby driving the first long material workpiece to be conveyed to the next processing station.

[0044] More specifically, the first driving mechanism 30 includes a driving motor 301, the output end of the driving motor 301 is drivingly connected to at least one worm gear transmission mechanism 302, the output end of each of the worm gear transmission mechanisms 302 is drivingly connected to a lead screw 303, the end of the lead screw 303 away from the worm gear transmission mechanism 302 is hinged with a connecting rod 304, the connecting rod 304 is fixedly connected to at least one horizontal cross bar 305, the horizontal cross bar 305 is provided with a vertical rod 306 corresponding to the position of each lifting rod 3, and the horizontal cross bar 305 is fixedly connected to the lifting rod 3 through the corresponding vertical rod 306. Specifically, two worm gear transmission mechanisms 302 are provided, and the two worm gear transmission mechanisms 302 are connected by a linkage mechanism. The driving motor 301 drives the two worm gear transmission mechanisms 302 to move synchronously, thereby driving the two screw rods 303 to rise and fall synchronously, and then drives multiple lifting rods 3 to rotate around their respective hinge positions through the connecting rod 304, the horizontal cross bar 305 and the vertical rod 306.

[0045] More specifically, the second driving mechanism 40 includes a second cylinder 401 and a rotating rod 402, the rotating rod 402 is rotatably connected to the frame 1 through a plurality of bearings 403, a first connecting rod 404 is hinged at one end of each first stop rod 4 close to the discharge side 12, a second connecting rod 405 is hinged at one end of each first connecting rod 404 away from the first stop rod 4, and an end of each second connecting rod 405 away from the first connecting rod 404 is fixedly connected to the rotating rod 402, and the output end of the second cylinder 401 is hingedly connected to one of the second connecting rods 405. In this embodiment, the second cylinder 401 extends to drive the second connecting rod 405 hinged thereto to rotate, and the rotation of the second connecting rod 405 drives the rotating rod 402 to rotate, thereby driving the remaining second connecting rods 405 to rotate, and then driving multiple first stop rods 4 to rotate around their respective hinged positions through the first connecting rod 404. By setting a second cylinder 401, multiple first stop rods 4 can be driven to rotate, which has a simple structure and low cost.

[0046] More specifically, the material stopper block 24 includes a top plane 241, and material stopper slopes 242 are provided on both sides of the top plane 241. In this embodiment, by providing the material stopper slope 242, when the control mechanism controls the first driving mechanism 30 to drive the lifting rod 3 to rotate and lower, a second angle is formed between the material stopper slope 242 on the material stopper block 24 near the discharge side and the first stopper rod 4. At this time, the second angle limits the first long workpiece, preventing the first long workpiece from falling back onto the first horizontal section 21, thereby achieving separation between the first long workpiece and the remaining long workpieces.

[0047] More specifically, each of the bearing rods 2 and each of the lifting rods 3 is provided with a blocking block 7 at one end close to the feed side 11. In this embodiment, by providing the blocking block 7, when the long workpiece located on the inclined section 22 falls back to the first horizontal section 21 along the inclined section 22 due to the effect of gravity, the blocking block 7 can limit the long workpiece to prevent it from rolling out of the first horizontal section 21.

[0048] Example 2

[0049] like Figures 1 to 6 As shown, Example 2 provides an automatic material distribution and conveying method, which is performed using the automatic material distribution and conveying system described in any one of Example 1, and the method comprises the following steps:

[0050] S1: A plurality of long workpieces are carried on the first horizontal section 21 of the carrying rod 2, wherein the long workpiece closest to the discharge side 12 is the first long workpiece, and the control mechanism starts the feeding program, the third driving mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby driving the second baffle 6 to swing downward to the avoidance position, and at the same time the second driving mechanism 40 drives the first baffle 4 to rotate and lift;

[0051] S2: The first driving mechanism 30 drives the lifting rod 3 to rotate and lift, so that an angle is formed between the lifting rod 3 and the first blocking rod 4, and the plurality of long workpieces move along the lifting rod 3 toward the discharge side 12 during the process of the lifting rod 3 rotating and lifting;

[0052] S3: When the first long workpiece moves to the angle position, the sensor detects the first long workpiece and feeds back the detection signal to the control mechanism, and the control mechanism controls the first driving mechanism 30 to drive the lifting rod 3 to rotate and lower. When the lifting rod 3 rotates to the initial position, the first long workpiece is carried between the blocking block 24 and the first blocking rod 4, and the remaining long workpieces are re-carried on the carrying rod 2 and are located on the inclined section 22 or the first horizontal section 21. The long workpiece located on the inclined section 22 falls back to the first horizontal section 21 along the inclined section 22 due to the action of gravity;

[0053] S4: The third driving mechanism 50 drives the eccentric conveying roller mechanism 5 to rotate, thereby driving the second baffle 6 to swing upward to the material blocking position. At this time, the horizontal height of the top of the eccentric conveying roller mechanism 5 is higher than the horizontal height of the second horizontal section 23. Then the second driving mechanism 40 drives the first baffle 4 to rotate and lower. At the same time, the first long workpiece is lowered to the top of the multiple eccentric conveying roller mechanisms 5 during the process of the first baffle rotating and lowering.

[0054] S5: The first long workpiece is conveyed to the next processing station along the eccentric conveying roller mechanism 5, completing the automatic material separation and conveying of a long workpiece. When the first long workpiece completely leaves the eccentric conveying roller mechanism 5, the control mechanism can start the next feeding program to automatically separate and convey the next long workpiece.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
