[0030] Example 1: Please refer to Figure 1-7 The present embodiment discloses a feeding device, comprising no less than two split bodies arranged in parallel, the split bodies comprising a frame 2, a movable frame 9 and a driving member, a first conveying chain 7, a second conveying chain 6 and a third conveying chain 8 which are parallel to each other are installed on the frame 2, the second conveying chain 6 moves up and down under the action of the driving member, the first conveying chain 7 and the second conveying chain 6 partially overlap but do not contact, the second conveying chain 6 partially overlap but do not contact the third conveying chain 8, and the first conveying chain 7 is located at one end of the third conveying chain 8.

[0031] A material separation device 12 which moves up and down under the action of a driving member is installed at the position of the frame 2 corresponding to the overlapping part of the second conveying chain 6 and the third conveying chain 8, and a material separation plate 5 which moves up and down under the action of a driving member is installed on the frame 2 between the first conveying chain 7 and the third conveying chain 8.

[0032] The mobile frame 9 is installed on the side of the frame 2 away from the first conveying chain 7, and the mobile frame 9 is slidably connected to the frame 2. The mobile frame 9 moves along the length direction of the first conveying chain 7 through a driving member. An automatic centering and tightening material arm 3 is installed on the end of the mobile frame 9 away from the first conveying chain 7.

[0033] The driving member includes but is not limited to a linear motor, a cylinder, a hydraulic cylinder or an electric telescopic rod.

[0034] Furthermore, a position switch 13 is provided at the position of the frame 2 corresponding to the partition plate 5; the position switch 13 includes but is not limited to a travel switch or a laser position switch.

[0035] The first conveying chain 7, the second conveying chain 6 and the third conveying chain 8 are all driven by corresponding motors to rotate their sprockets. The motors are electrically connected to the controller. The controller is a PLC controller or an industrial computer. The controller can control the operation of the first conveying chain 7, the second conveying chain 6 and the third conveying chain 8 respectively. The controller can control the operation of different driving parts respectively. The controller detects the position of the pipe through the position switch 13.

[0036] The motor, linear motor, cylinder, hydraulic cylinder, electric telescopic rod and controller used in this embodiment are all commonly used electronic components in the prior art. Their working methods and circuit structures are well-known technologies and will not be described in detail here.

[0037] The working process and principle of this embodiment are:

[0038] Feeding process:

[0039] 1: The pipes are first arranged on the first conveyor chain 7;

[0040] 2: The first conveyor chain 7 works to carry the pipe forward to the second conveyor chain 6, and the material separation device 12 is in a raised state, and the pipes are gathered and arranged at the material separation device 12;

[0041] The material separation device 12 descends, and the third conveyor chain 8 is lifted by the driving member corresponding to the second conveyor chain 6, so that the pipes are separated from the first conveyor chain 7. The second conveyor chain 6 carries the pipes to continue moving, and the material separation plate 5 is in a raised state, and the pipes are gathered and arranged at the material separation plate 5.

[0042] 3: The material separator 5 descends, and the second conveyor chain 6 carries the pipe to continue to move to the third conveyor chain 8. The pipe touches the position switch 13, the second conveyor chain 6 stops, and the third conveyor chain 8 carries the pipe forward. At this time, the separation of the pipe is achieved.

[0043] 4: The automatic centering and tightening arm 3 turns up and clamps the pipe, so that the pipe is in the center position, and the mobile frame 9 is pushed out by its corresponding driving member and extends out of the frame 2.

[0044] 5: The pipe chuck clamps the pipe, the automatic centering and tightening arm 3 flips over and resets, and the mobile frame 9 is retracted to complete one feeding.

[0045] The feeding equipment adopts three conveyor chains for segmented feeding, which is stable and reliable, convenient for material separation and division, and has strong versatility.

[0046] Embodiment 2: Figure 1 and Figure 2 As shown, this embodiment discloses a feeding device, whose structure is roughly the same as that of the first embodiment, except that the outer sides of the two outermost parts of this embodiment are both installed with limit baffles 1; the limit baffles 1 prevent the pipe from sliding out along its length direction.

[0047] The split body realizes power transmission of the first conveying chain 7, the second conveying chain 6 and the third conveying chain 8 through the transmission shaft 10; realizes the power linkage between the split bodies, ensures that the first conveying chain 7, the second conveying chain 6 and the third conveying chain 8 of different split bodies work synchronously, ensures the stability of pipe movement, and reduces the controlled units.

[0048] Embodiment 3: Figure 1 and Figure 3 As shown, this embodiment discloses a feeding device, and its structure is substantially the same as that of the first embodiment, except that an inclined plate 4 with a raised middle portion is provided at the position of the frame 2 corresponding to the partition plate 5 of this embodiment.

[0049] The working process and principle of this embodiment are: in step 3 of the feeding process, the pipe touches the position switch 13, and the second conveying chain 6 stops. At this time, the pipe in front has just passed the highest point of the inclined plate 4, and the pipe moves forward under the action of gravity. The third conveying chain 8 carries the pipe forward, making it convenient to separate the gathered pipes.

[0050] Embodiment 4: Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, this embodiment discloses a feeding device, and its structure is substantially the same as that of the first embodiment, except that the automatic centering and clamping arm 3 of this embodiment includes two clamping mechanisms arranged opposite to each other, and the clamping mechanism includes a flipping mechanism 31, a roller 32, a roller frame 33 and a clamping cylinder 11. The flipping mechanism 31 reciprocates along the length direction of the mobile frame 9. A U-shaped roller frame 33 is fixed on the output shaft of the flipping mechanism 31, and a roller 32 is mounted on the roller frame 33. The plane in which the roller 32 rotates with the flipping mechanism 31 is perpendicular to the length direction of the mobile frame 9, and the two ends of the clamping cylinder 11 are respectively connected to the flipping mechanism 31 and the outer side of the mobile frame 9.

[0051] The turning mechanism 31 includes but is not limited to a stepping motor or a turning cylinder.

[0052] Furthermore, the automatic centering and clamping arm 3 also includes a centering clamping device arranged on the movable frame 9, and the centering clamping device includes two parallel racks and a gear located between the two racks. The two racks are respectively meshed with the gears, and the two racks are restricted to move along their length directions. The two flipping mechanisms 31 are respectively installed on the two racks of the centering clamping device.

[0053] The working process and principle of this embodiment are:

[0054] When the automatic centering and tightening arm 3 needs to tighten the pipe, the flipping mechanism 31 drives the roller frame 33 to flip and stand upright, the clamping cylinder 11 extends to move the clamping mechanisms toward each other, the rollers 32 clamp the pipe so that the pipe is in the center position, and the mobile frame 9 is pushed out by its corresponding driving member and extends out of the frame 2.

[0055] The automatic centering and clamping arm 3 clamps the pipe to the center position and can withstand large loads, making feeding more accurate.

[0056] The automatic centering and clamping arm 3 can also be replaced by an electric clamping claw that can move up and down.

[0057] Embodiment 5: Figure 5 and Figure 6 As shown, this embodiment discloses a feeding device, and its structure is substantially the same as that of the fourth embodiment, except that this embodiment also includes an electric alignment device, which includes an automatic centering and tightening material arm 3 and a motor 14. The motor 14 is mounted on a roller frame 33, and the motor 14 drives the roller 32 to rotate; when the electric alignment device clamps the pipe, the motor 14 can drive the roller 32 to rotate, so that the pipe moves along its length direction, thereby adjusting the position of the pipe.

[0058] The working process and principle of this embodiment are:

[0059] During the feeding process of the pipe, the position of the pipe is usually random, so it is necessary to align one side of the pipe before clamping it with the chuck to facilitate clamping and cutting. Most existing alignment devices use cross beams or ground rails, which makes the entire mechanism huge and the cutting structure complex; the motor 14 can drive the roller 32 to rotate, so that the pipe moves along its length direction, thereby adjusting the position of the pipe. The electric alignment device has a simple structure and a small size, and can effectively align pipes of different lengths.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
