DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-12 As shown, the present invention discloses a feeding device, comprising a frame 1, on which a feeding bin 2, a baffle mechanism 3 and a feeding mechanism 4 are arranged, the feeding bin 2 is provided with a discharge channel 21, the baffle mechanism 3 slides through the discharge channel 21 to control the discharge, and the feeding mechanism 4 is arranged at the outlet 211 of the discharge channel 21;

[0035] The feeding mechanism 4 includes a sliding plate 41, a driving member 42, a clamping assembly 43, and a clamping assembly 44. The driving member 42 is fixed on the sliding plate 41, and the clamping assembly 43 and the clamping assembly 44 are respectively slidably connected to the sliding plate 41. The output shaft of the driving member 42 is fixedly connected to the clamping assembly 43. A switching member 45 is provided between the clamping assembly 43 and the clamping assembly 44 to make the sliding directions of the two opposite, so that the clamping assembly 43 and the clamping assembly 44 are close to or separated from each other to realize opening and closing. The telescopic direction of the output shaft is the same as the sliding direction of the clamping component 43; when in use, the pipe is placed in the loading bin 2, and the pipe falls from the discharge channel 21 to the baffle mechanism 3, and the baffle mechanism 3 makes the pipes fall one by one to the feeding mechanism 4, and through the cooperation of the sliding plate 41, the driving member 42, the clamping component 43, the clamping component 44 and the switching member 45, the clamping component 43 of the feeding mechanism 4 and the clamping component 44 are separated from or approached to each other, and the pipe falls to the feeding mechanism 4 and is clamped, preparing for the subsequent transmission processing.

[0036] like Figure 2-4 As shown, further, in order to realize the clamping of the pipe mechanism by the feeding mechanism 4, the clamping assembly 43 includes a guide rod 431, a clamping plate 432, and a plurality of clamps 433 arranged on the clamping plate 432, one end of the guide rod 431 is slidably connected to the sliding plate 41, and the other end is fixedly connected to the clamping plate 432, and the output shaft of the driving member 42 is fixedly connected to the clamping plate 432; the clamping assembly 44 includes a guide rod 441, a clamping plate 432, and a plurality of clamps 433 arranged on the clamping plate 432. Plate 2 442, and a plurality of clamps 2 443 arranged on clamp plate 2 442, one end of the guide rod 2 441 is slidably connected to the sliding plate 41, and the other end passes through the clamp plate 1 432 and is fixedly connected to the clamp plate 2 442; the switching member 45 rotatably connected to the sliding plate 41 is respectively engaged with the guide rod 1 431 and the guide rod 2 441; during the transmission process, the guide rod 1 431 and the guide rod 2 441 slide in opposite directions under the action of the switching member 45.

[0037] Furthermore, the switching member 45 is gear-shaped, and a toothed structure is provided on the guide rod 1 431 and the guide rod 2 441. The guide rod 1 431 and the guide rod 2 441 are provided with a rack 46 corresponding to the switching member 45. The extension directions of the racks 46 of the guide rod 1 431 and the guide rod 2 441 are parallel. When the driving member 1 42 drives the clamping assembly 1 43, during the transmission process, the driving member 1 42 drives the splint 1 432 forward, and the guide rod 1 431 also moves forward. The switching member 45 is meshed and connected with the racks 46 on the guide rod 1 431 and the guide rod 2 441, so that the sliding directions of the guide rod 1 431 and the guide rod 2 441 are opposite. Therefore, the guide rod 2 441 moves backward. 442 is fixedly connected to the guide rod 441, thereby driving the second clamp 442 to move backward, so that the first clamp 432 and the second clamp 442 are close to each other, thereby clamping the pipe; similarly, when the driving member 42 drives the first clamp 432 backward, the first clamp 432 moves backward, driving the guide rod 431 backward as well, and the switching member 45 is meshedly connected with the guide rod 431 and the rack 46 on the guide rod 441, so that the guide rod 441 moves forward, and since the second clamp 442 is fixedly connected to the guide rod 441 and thereby drives the second clamp 442 to move forward, the first clamp 432 and the second clamp 442 move away from each other, thereby receiving or releasing the pipe.

[0038] Furthermore, in order to achieve better clamping of the pipe and adapt to the shape and structural characteristics of the pipe, the clamp 1 433 is provided with a clamping portion 1 434 extending obliquely upward, and the clamp 2 443 is provided with a clamping portion 2 444 extending obliquely upward. The clamp 1 434 and the clamp 2 444 have the same inclination angle and are arranged in opposite directions. The clamp 1 433 and the clamp 2 443 are arranged symmetrically in an alternating manner. In the clamped state, the clamp 1 434 and the clamp 2 444 form a clamping area 47.

[0039] Preferably, since the hose is a flexible pipe, its material itself has a certain elasticity and flexibility, which makes the hose naturally bend when there is no external force. In order to better adapt to this characteristic of the pipe and achieve effective grasping, several groups of clamps 1 433 and clamps 2 443 are evenly distributed on guide rod 1 431 and guide rod 2 441 to ensure that the pipe is evenly stressed during the clamping process and avoid damage to the pipe due to uneven force. Such a design can not only ensure the stability of the pipe during the grasping process, but also facilitate subsequent processing and transportation. In addition, this design also takes into account the simplicity and flexibility of operation. The opening and closing of splint 1 432 and splint 2 442 can be achieved through simple operation, which reduces the complexity of operation and improves work efficiency. At the same time, the design of clamp 1 433 and clamp 2 443 also allows adjustment according to the size and shape of the pipe to adapt to pipes of different specifications.

[0040] like Figure 5 As shown, the feeding mechanism 4 also includes a second driving member 48, the extension and retraction direction of the output shaft of the second driving member 48 is consistent with the sliding direction of the sliding plate 41, and a push block 412 is fixedly provided on the sliding plate 41. The output shaft of the second driving member 48 is fixedly connected to the push block 412, so that the second driving member 48 drives the sliding of the feeding mechanism 4; at least one sliding block 49 is fixedly provided on the frame 1, and a track 411 adapted to the sliding block 49 is provided at the bottom of the sliding plate 41. During the transmission process, the second driving member 48 drives the track 411 of the sliding plate 41 to slide on the sliding block 49 to realize the transmission of the pipe. At the same time, the length of the track 411 limits the sliding distance of the sliding plate 41.

[0041] like Figure 6 As shown, in order to realize the one-by-one falling of the pipes, the discharge channel 21 includes a side plate 1 212 and a side plate 213, the baffle mechanism 3 includes a connecting rod 31, a moving rod 32, a cylinder 1 33 and a cylinder 2 34, the connecting rod 31 is located below the moving rod 32 and the spacing is the diameter of a pipe, the cylinder 1 33 is fixedly connected to the connecting rod 31, the cylinder 2 34 is fixedly connected to the moving rod 32, the cylinder 1 33 drives the connecting rod 31 to slide and connect with the side plate 1 212 and the side plate 2 213, the cylinder 2 34 drives the moving rod 32 to slide and connect with the side plate 2 213, the connecting rod 31 and the moving rod 32 interact with each other to make the pipes fall one by one to the feeding mechanism 4.

[0042] Furthermore, in order to prevent the moving rod 32 from damaging the pipe when it is extended to intercept the pipe, an end surface 321 adapted to the shape of the pipe is provided at the end of the moving rod 32, thereby preventing the pipe from being damaged.

[0043] When the feeding mechanism 4 is not directly below the outlet 211, a number of pipes fall from the discharge channel 21, the connecting rod 31 is connected to the side plate 213, and the pipes fall onto the connecting rod 31 and are intercepted. When the feeding mechanism 4 reaches directly below the opening, the moving rod 32 is driven by the cylinder 2 34 to move to the side plate 1 212. At this time, there is only one pipe on the connecting rod 31. The connecting rod 31 is driven by the cylinder 1 33 to move to the side plate 1 212, and the pipes fall to the feeding mechanism 4.

[0044] Furthermore, since there is no obstruction in the horizontal direction between the side plate 1 212 and the side plate 213, in order to prevent the pipe from deviating and falling when it falls from the discharge channel 21 to the feeding mechanism 4, and thus failing to reach the pipe groove of the feeding mechanism 4, the discharge channel 21 also includes a baffle 214, and the baffle 214 is fixedly connected to the side plate 1 212 and the side plate 213, and a through hole 215 is also provided on the baffle 214. By providing the through hole 215, the falling of the pipe and whether the pipe falls to the feeding mechanism 4 one by one can be well observed, which is convenient for observation, and the extending direction of the baffle 214 is consistent with the falling direction of the pipe, so that the pipe can be accurately positioned when it falls to the feeding mechanism 4, effectively reducing the deviation generated during the falling process, improving the accuracy of processing and transmission, and improving the efficiency of subsequent transmission and processing of the pipe.

[0045] like Fig.12 As shown, since several pipes are placed in the upper bin 2 at the same time, the pipes will be squeezed and overlapped, and thus piled up at the discharge channel 21, and the pipes cannot fall off. Therefore, a cam 7 is rotatably connected to one side of the upper bin 2, and a through hole 22 adapted to the cam 7 is provided at the entrance of the discharge channel 21 of the upper bin 2. The cam 7 includes a smooth portion 71 and a raised portion 72. When the cam 7 rotates, the raised portion 72 extends through the through hole 22 into the discharge channel 21. Through the arrangement of the cam 7, the pipes will not overlap, thereby preventing the pipes from being blocked at the discharge channel 21, thereby improving work efficiency.

[0046] like Figure 7-9 As shown, a gripping mechanism 5 is provided on one side of the loading bin 2. In order to better grip the pipes transported from the feeding mechanism 4, the gripping mechanism 5 includes a driving member 3 51, a screw rod 52, a nut 53, a bracket 54 and a plurality of finger cylinders 55 with a clamping function arranged on the bracket 54. The driving member 3 51 drives the screw rod 52 to rotate to drive the nut 53 sleeved on the screw rod 52 and the bracket 54 fixedly connected to the nut 53 to rise and fall synchronously.

[0047] The finger cylinder 55 includes a symmetrically arranged clamping jaw 1 551, a second clamping jaw 552 and a third cylinder 553. The third cylinder 553 controls the opening and closing of the clamping jaw 1 551 and the second clamping jaw 552 to grasp the pipe. The end of the clamping jaw 1 551 is provided with an arc surface 1 554, and the end of the clamping jaw 2 552 is provided with an arc surface 2 555. This design takes into account the circular cross-sectional characteristics of the pipe. By setting the corresponding arc surface, it fits tightly with the outer surface of the pipe to provide stable support, allowing the gripping mechanism 5 to maintain appropriate clamping force when grasping pipes of different sizes, avoiding the pipe from slipping during transportation, so that the clamping jaw 1 551 and the second clamping jaw 552 can form a smooth clamping area when clamping, reducing damage to the pipe, while providing a stable gripping force, so that the pipe can be stably grasped from the feeding mechanism 4.

[0048] Furthermore, in order to enhance the stability of grasping, a plurality of clamping claws 551 and clamping claws 552 are evenly arranged on the bracket 54. This layout can ensure that the pipe is subjected to uniform support force during the grasping and lifting process, thereby maintaining the balance of the pipe; at the same time, it reduces the risk of tipping over due to the shift of the center of gravity during the rising and falling of the pipe, provides a stable support point, and the center of gravity of the pipe is effectively maintained in the center position, ensuring the stability of the pipe in the vertical direction and avoiding tipping over due to vibration or swinging during the lifting process.

[0049] Preferably, cylinder three 553 is not only responsible for driving the opening and closing of the clamping jaws, but also has an adjustment function, allowing the operator to adjust the clamping force according to the size and material of the pipe to achieve the best grasping effect.

[0050] The screw rod 52 is disposed in the middle of the bracket 54 to achieve a smooth rise of the bracket 54 and uniform force distribution.

[0051] The gripper mechanism 5 has three positions in this embodiment. First, when the feeding mechanism 4 has not yet reached directly below the gripper mechanism 5, the gripper mechanism 5 is located at the initial position. When the feeding mechanism 4 reaches directly below the gripper mechanism 5, the clamp 1 433 and the clamp 2 443 of the feeding mechanism 4 are separated from each other, and the gripper mechanism 5 moves downward under the drive of the driving member 3 51 to reach the clamping area 47 of the feeding mechanism 4. The clamp 1 551 and the clamp 2 552 are clamped under the drive of the cylinder 3 553, and the pipe is clamped. In order to prevent the feeding mechanism 4 from colliding with the gripper mechanism 5, the gripper mechanism 5 moves upward to the initial position under the action of the driving member 3 51 after grabbing the pipe. After reaching the position, the feeding mechanism 4 moves back to directly below the outlet 211, and the gripper mechanism 5 moves downward under the action of the driving member 3 51.

[0052] like Figure 10-11A transmission mechanism 6 is provided on one side of the gripper mechanism 5, and the transmission mechanism 6 includes a transmission plate 61 slidably connected to the frame 1, at least one transmission block 62 fixed on the transmission plate 61, and a driving member 63 for driving the transmission plate 61 to move. A fixing position 621 for fixing the pipe is provided on the transmission block 62. When the gripper mechanism 5 moves from the initial position to the transmission block 62 of the transmission mechanism 6 under the action of the driving member 3 51, the pipe is released into the fixed position 621, thereby realizing the loading of the entire pipe and preparing for the subsequent processing and transmission of the pipe.

[0053] The working principle of the present invention is described in detail below;

[0054] A number of pipes are placed in the upper bin 2, and after passing through the cam 7, they fall through the discharge channel 21 to the connecting rod 31 of the baffle mechanism 3. At this time, the feeding mechanism 4 is located directly below the outlet 211, and the switching member 45 and the driving member 1 42 cooperate to separate the clamping assembly 1 43 and the clamping assembly 2 44 of the feeding mechanism 4 from each other. At this time, the moving rod 32 is driven by the cylinder 2 34 to connect with the side plate 1 212, and the connecting rod 31 is driven by the cylinder 1 33 to move to the side plate 1 212, so that the pipes fall one by one. The pipes fall to the feeding mechanism 4, and then the clamping assembly 1 43 and the clamping assembly 2 44 are close to each other to clamp the pipes. The feeding mechanism 4 is driven by the driving member 2 4 8 drives the feeding mechanism 4 to arrive directly below the gripping mechanism 5. At this time, the clamping component 1 43 and the clamping component 2 44 are separated from each other. The gripping mechanism 5 is driven by the driving component 3 51 and the screw rod 52 to move to the feeding mechanism 4 to clamp the pipe, and then moves upward to the initial position so that the feeding mechanism 4 does not collide with the gripping mechanism 5 when it moves to the outlet 211. Thereafter, the gripping mechanism 5 moves to the transmission mechanism 6 to release the pipe to the fixed position 621 on the transmission block 62. The transmission mechanism 6 is driven by the driving component 4 63 to move to the next processing mechanism. After releasing the pipe, the gripping mechanism 5 moves upward to the initial position, and the cycle is repeated, thereby realizing the automatic loading of the pipe and preparing for the subsequent transmission and processing of the pipe.

[0055] The innovative point of the present invention is that the stacked pipes are separated by the rotation of the cam in the through hole in the upper bin, so that the discharge of the pipes is smooth; by setting a baffle mechanism, the connecting rod is slidably connected with the side plate two, and the pipes fall onto the connecting rod and are intercepted. When the feeding mechanism reaches directly below the opening, the moving rod is driven by the cylinder two to move to the side plate one, and the connecting rod is driven by the cylinder one to move to the side plate one, so that the pipes fall one by one.
