Detailed implementation mode

[0030] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] As Figures 1 to 10 shown, the present utility model provides a feeding device for a faucet pull-out pipe, including: a pipe body clamping frame and a conveying device for conveying the pipe body clamping frame. The pipe body clamping frame includes a horizontal plate 100 and a pipe body clamping device 110. Two pipe body clamping devices 110 are fixedly installed at the bottom of the horizontal plate 100 along its length direction.

[0032] The pipe body clamping device 110 includes a fixed clamping block 112, a movable clamping block 111, a first guide rod, a first limiting block 113 and a first elastic member. The fixed clamping block 112 is fixedly installed at the bottom of the horizontal plate 100. A first blind hole is opened on one side of the fixed clamping block 112. A first through hole is opened in the first blind hole. The diameter of the first through hole is smaller than the diameter of the first blind hole. The first guide rod passes through the first blind hole and is slidably connected with the first through hole. One end of the first guide rod close to the first through hole is fixedly connected with the movable clamping block 111, and the other end is fixedly connected with the first limiting block 113. One end of the first elastic member abuts in the first blind hole and the other end abuts on the first limiting block 113. When pushing the first guide rod from the first limiting block 113 end, the first elastic member is compressed, and the first guide rod drives the movable clamping block 111 to move away from the fixed clamping block 112; when releasing the first limiting block 113, the first elastic member extends, driving the first limiting block 113 to move away from the fixed clamping block 112, and the first guide rod drives the movable clamping block 111 to move close to the fixed clamping block 112. Clamping grooves for clamping the pipe body 600 are opened on the sides of the fixed clamping block 112 and the movable clamping block 111 close to each other.

[0033] Clamping block relaxation devices 460 are symmetrically arranged at the bottoms of the first lifting device 500 and the second lifting device 400. The clamping block relaxation device 460 includes a pushing block 462 and a driving device 461. The pushing block 462 is arranged corresponding to the position of the first limiting block 113. The driving device 461 drives the pushing block 462 to move in a direction close to or away from the first limiting block 113, and the pushing block 462 pushes the first limiting block 113 to move in a direction close to the fixed clamping block 112.

[0034] A limiting device is further arranged on the second lifting device 400. The limiting device includes a third elastic member, a nut, and a second limiting block, a connecting column, a movable column, and a threaded column connected in sequence from bottom to top. The diameter of the connecting column is smaller than that of the second limiting block. The movable column is a cylinder with two sides cut off. The threaded column is threadedly connected to the nut. Two limiting devices are symmetrically arranged on the lifting plate 440. An activity hole for slidably connecting with the movable column is formed on the lifting plate 440. The third elastic member is arranged between the lifting plate 440 and the second limiting block. The position of the limiting device corresponds to the position of the pipe body clamping device 110. A third through hole 116 is formed on the cross plate 100 between the fixed clamping block 112 and the movable clamping block 111. The third through hole 116 is arranged below the second limiting block.

[0035] In this embodiment, during the feeding process, the two driving devices 461 at the bottom of the second lifting device 400 drive the pushing block 462 to move in a direction close to the first limiting block 113, and drive the first limiting block 113 and the first guide rod to move towards the movable clamping block 111, so that the movable clamping block 111 moves away from the fixed clamping block 112, and the first elastic member is compressed. Subsequently, an operator grasps both ends of the pipe body 600, inserts the end of the pipe body 600 between the movable clamping block 111 and the fixed clamping block 112, and makes the end of the pipe body 600 pass through the third through hole 116 and abut against the lower part of the second limiting block, thereby limiting the length of the pipe body 600 extending out of the third through hole 116. Under the action of the upward force at the end of the pipe body 600, the movable column moves upward along the third through hole 116, and the third elastic member is compressed to absorb the upward force at the end of the pipe body 600, playing a role in protecting the end of the pipe body 600. Then the driving device 461 drives the pushing block 462 to reset, so that the first limiting block 113 is no longer pushed by the pushing block 462. Under the action of the elastic force of the first elastic member, the first limiting block 113 is pushed in a direction close to the driving device 461, driving the first guide rod, and further driving the movable clamping block 111 to move in a direction close to the fixed clamping block 112, so that the movable clamping block 111 and the fixed clamping block 112 clamp the pipe body 600. At this time, the pipe body 600 is hung on the pipe body clamping rack in a U shape.

[0036] In the above embodiment, the first elastic member and the third elastic member are both springs, and the driving device 461 is a cylinder.

[0037] The conveying device includes a lower conveyor belt 200, an upper conveyor belt 300, a first lifting device 500 and a second lifting device 400. The lower conveyor belt 200 is arranged below the upper conveyor belt 300. The first lifting device 500 is arranged at the same end of the lower conveyor belt 200 and the upper conveyor belt 300. The second lifting device 400 is arranged at the other end of the lower conveyor belt 200 and the upper conveyor belt 300. The lower conveyor belt 200 conveys in the direction towards the first lifting device 500, and the conveying direction of the upper conveyor belt 300 is opposite to that of the lower conveyor belt 200. The first lifting device 500 is used to convey the cross plate 100 on the lower conveyor belt 200 upwards to the upper conveyor belt 300, and the second lifting device 400 is used to convey the cross plate 100 on the upper conveyor belt 300 downwards to the lower conveyor belt 200. The lower conveyor belt 200 is composed of two parallel first conveyor belts, and the upper conveyor belt 300 is composed of two parallel second conveyor belts.

[0038] In this embodiment, the distance between the two first conveyor belts and the distance between the two second conveyor belts should be less than the length of the cross plate 100, so that the cross plate 100 can be placed between the two first conveyor belts or between the two second conveyor belts. The two first conveyor belts are separated from each other, so that the pipe body 600 can pass through between the two first conveyor belts. In order to make the pipe body clamping bracket run smoothly on the first conveyor belt and the second conveyor belt, guide wheels 115 are fixedly installed at both ends of the cross plate 100. During the process of conveying the pipe body clamping bracket, the guide wheels 115 at both ends of the cross plate 100 are in contact with the side walls of the first conveyor belt and the second conveyor belt, making the transportation process smooth. In the above embodiment, the guide wheels 115 are bearings.

[0039] Both the first lifting device 500 and the second lifting device 400 include a bracket 410, a lifting cylinder 420, a second guide rod 430, a lifting plate 440 and a grasping groove 45%. The bracket 410 is arranged obliquely above the upper conveyor belt 300. The lifting cylinder 420 is installed on the bracket 410. The lifting plate 440 is installed on the piston rod of the lifting cylinder 420. Two second guide rods 430 are symmetrically arranged at the top of the lifting plate 440. Guide holes for the second guide rods 430 to pass through are opened on the bracket 410. Two grasping grooves 450 are symmetrically arranged at both ends of the bottom of the lifting plate 440. The grasping grooves 450 are used to drive the pipe body clamping bracket to lift and lower.

[0040] Positioning cylinders are symmetrically arranged at both ends of the lifting plate 440. A positioning rod is installed on the piston rod of the positioning cylinder. A chamfer is arranged at the lower end of the positioning rod. A second through hole for the positioning rod to pass through is opened on the grasping groove 450, and a positioning hole 114 matching the positioning rod is opened on the cross plate 100.

[0041] In this embodiment, the opening of the grasping groove 450 faces the direction of the lower conveyor belt 200. In the initial state, the grasping groove 450 is arranged on one side of the lower conveyor belt 200, and the opening height of the grasping groove 450 is equal to the height of the lower conveyor belt 200. After the lower conveyor belt 200 transports the pipe clamping frame to the grasping groove 450 of the first lifting device 500, the positioning cylinder on the lifting plate 440 drives the positioning rod to move downward, so that the positioning column is inserted into the positioning hole 114 opened on the cross plate 100 to position the cross plate 100. Subsequently, the manipulator in the next process clamps both ends of the pipe 600 under the cross plate 100, and then the clamping block releasing device 460 at the bottom of the first lifting device 500 acts to separate the movable clamping block 111 and the fixed clamping block 112 that clamp the pipe 600. The manipulator in the next process takes away the pipe 600 from the pipe clamping device 110 and enters the next process.

[0042] One end of the first lifting device 500 away from the second lifting device 400 is fixedly installed with an L-shaped bracket 510. A first pushing cylinder 520 is installed at the bottom of the L-shaped bracket 510. The piston rod of the first pushing cylinder 520 is connected to the first push plate. The height of the first pushing cylinder 520 is slightly higher than that of the upper conveyor belt 300. The first pushing cylinder 520 is used to push the pipe clamping frame in the grasping groove 450 into the upper conveyor belt 300.

[0043] In this embodiment, after the manipulator in the next process takes away the pipe 600 at the end of the lower conveyor belt 200, the first lifting device 500 rises to lift the cross plate 100 to the same height as the upper conveyor belt 300. At this time, the positioning cylinder drives the positioning column to rise, so that the positioning column is separated from the cross plate 100. The first pushing cylinder 520 drives the first push plate to push the cross plate 100 into the upper conveyor belt 300. The upper conveyor belt 300 drives the cross plate 100 into the grasping groove 450 of the second lifting device 400 and positions and fixes it through the positioning cylinder and the positioning column of the second lifting device 400. The second lifting device 400 drives the cross plate 100 to move from the upper conveyor belt 300 to the corresponding height of the lower conveyor belt 200, and then the positioning cylinder on the second lifting device 400 acts to separate the positioning column from the cross plate 100.

[0044] On one side of the lower conveyor belt 200 close to the second lifting device 400, a second pushing cylinder 470 is provided. The second pushing cylinder 470 is arranged between the upper conveyor belt 300 and the lower conveyor belt 200. A fixing block 471 is fixedly connected to the end of the piston rod of the second pushing cylinder 470. At both ends of the bottom of the fixing block 471, connecting ears are integrally formed. A rotating shaft 473 is installed between the two connecting ears. A rotating block 472 is rotatably connected to the rotating shaft 473. The cross-section of the rotating block 472 is in the shape of a parallelogram. A second elastic member 474 is arranged between the fixing block 471 and the rotating block 472, so that a certain angle is formed between the fixing block 471 and the rotating block 472. A first mounting hole is formed at the bottom of the fixing block 471, and a second mounting hole corresponding to the position of the first mounting hole is formed at the top of the rotating block 472. Both ends of the second elastic member 474 are respectively installed in the first mounting hole and the second mounting hole. The rotating block 472 is used to drive the pipe clamping frame into the lower conveyor belt 200.

[0045] In this embodiment, under the action of the elastic force of the second elastic member 474, the rotating block 472 is separated from the lower surface of the fixing block 471 and forms an angle. The second pushing cylinder 470 drives the rotating block 472 to move from the first lifting device 500 towards the second lifting device 400. The rotating block 472 abuts against the cross plate 100. When the rotating block 472 moves to the side of the second lifting device 400 far from the first lifting device 500, the bottom of the rotating block 472 is separated from the cross plate 100. Under the action of the second elastic member 474, the rotating block 472 rotates counterclockwise by a certain angle, so that the lowermost end of the rotating block 472 is lower than the upper surface of the cross plate 100. At this time, the second pushing cylinder 470 drives the rotating block 472 to move towards the cross plate 100. The rotating block 472 catches the cross plate 100, and the upper surface of the rotating block 472 abuts against the fixing block 471, making the rotating block 472 unable to rotate counterclockwise. Thus, the cross plate 100 is pulled into the lower conveyor belt 200 under the pulling of the second pushing cylinder 470. In the above embodiment, the second elastic member 474 is a spring.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
