Description

[Technical field]

[0001] The invention belongs to the technical field of pipe processing, and in particular relates to a pipe sheathing device. [Background technology]

[0002] When processing steel pipes, according to process requirements, multiple sheaths need to be respectively provided on both ends of the pipes, and the sheaths need to be positioned on the sheaths. Traditional technologies mostly use manual methods to carry out the sheathing process of steel pipes, resulting in low production efficiency. In order to improve production efficiency and the quality of sheathing, it is necessary to design relevant steel pipe sheathing equipment.

[0003] In the prior art, for example, the wire harness sheathing device and method disclosed in patent publication number CN111086202A include a machine, on which a first station, a second station, a third station and a fourth station are provided; the first station is used to install a wire feeding device for conveying the wire harness; the second station and the third station are both provided with a first mounting position for installing a first sleeve device and a second mounting position for installing a second sleeve device; the fourth station is used to install a heat shrink device; the second station and the third station can be selectively installed with the first sleeve device or the second sleeve device, respectively, so that the two ends of the wire harness can be sheathed, or the two ends of the wire harness can be sheathed with heat shrink tubes, or the two ends of the wire harness can be sheathed and heat shrink tubes can be simultaneously worn. However, in this solution, the sleeve is a cut finished product, which is transported to the sleeve device through the sleeve conveying device for sleeve coating.

[0041] The pipe feeding device 1 includes a pipe storage bin 11, a first motor 12 fixed on a machine table 8, a rotating shaft 13 driven by the first motor 12 to rotate around a horizontal axis, a turntable 14 rotatably arranged on the rotating shaft 13, and a cam 15 arranged inside the turntable 14 and fixed on the rotating shaft 13. The outer periphery of the turntable 14 is provided with a plurality of first slots 16 at equal angles, a plurality of elastic hook assemblies 17 that extend radially into the first slots 16 and hook the pipe 200, and a roller 18 that is arranged at the lower end of the elastic hook assembly 17 and is rollingly arranged on the cam 15.

[0042] The elastic hook assembly 17 includes a hook 171 for clamping the pipe 200 and extending radially along the rotating disk 14, a second support shaft 172 inserted in the middle of the hook 171 and extending horizontally, two fixing blocks 173 symmetrically fixed on both end surfaces of the rotating disk 14, and two elastic members 174 whose upper ends are connected to both ends of the second support shaft 172 and whose lower ends are connected to the fixing blocks 173. The elastic hook assembly 17 is provided, and when the first motor 12 drives the rotating shaft 13 to drive the rotating disk 14 to rotate, the roller 18 at the lower end of the elastic hook assembly 17 rotates on the cam 15, so that the hook 171 extends out to hook the pipe, so that the pipe 200 will not fall when the rotating disk 14 rotates.

[0043] The loading process of the pipe loading device 1 is as follows: a stack of pipes 200 are placed on the pipe storage bin 11, the first motor 12 drives the rotating shaft 13 to drive the turntable 14 to rotate, and the roller 18 at the lower end of the elastic hook assembly 17 rotates on the cam 15, so that the hook 171 extends out to hook the pipe, and the turntable 14 continues to rotate. The turntable 14 carries the pipe from the pipe storage bin 11 to one side of the pipe conveying device 2. When the pipe is rotated to a certain angle, the pipe will fall from the first slot 16 to the pipe conveying device 2 due to gravity.

[0045] In this embodiment, three parallel conveyor belts 22 are provided, and each conveyor belt 22 is provided with a plurality of receiving blocks 23, and the receiving blocks 23 on each conveyor belt 22 correspond to each other on the left and right, and the three receiving blocks 23 on the same horizontal line jointly clamp a pipe 200, and the length direction of the pipe 200 is perpendicular to the conveying direction of the conveyor belt 22; in order to avoid the sheathing device 6 on both sides, the clamping assembly 26 is arranged on the side of the middle conveyor belt 22.

[0046] The receiving block 23 is provided with a second clamping groove 231 for clamping the pipe 200; the first clamping assembly 26 includes a clamping cylinder 261 and a pair of clamping claws 262 driven by the clamping cylinder 261 to open or clamp. When the pipe 200 is transported, the pipe 200 is clamped by the second clamping groove 231. In order to ensure that the pipe will not be separated from the second clamping groove 231 during the transportation process, a pressing rod 27 is also provided above the conveyor belt 22; when the pipe is sheathed, the clamping cylinder 261 is required to drive the clamping claws 262 to clamp the pipe, so that the pipe will not shake when sheathing, which is convenient for smooth sheathing operation.

[0047] The blocking assembly 25 includes a blocking cylinder and a blocking pin driven by the blocking cylinder to move up and down. When the turntable 14 carries the pipe from the pipe storage bin 11 to the side of the pipe conveying device 2, after the pipe is rotated to a certain angle, the pipe 200 will fall from the first card slot 16 due to gravity, and the fallen pipe is introduced into the receiving card block 23 at the front of the conveyor belt 22 through the guide plate 24. At the same time, the blocking cylinder extends to make the blocking pin block the pipe, assisting the pipe to smoothly enter the receiving card block 23 to prevent the pipe from continuing to roll forward. If the pipe needs to be transported, the blocking cylinder can be retracted.

[0048] In this embodiment, three pipe collecting mechanisms 3 are arranged along the length direction of the pipe. The middle pipe collecting mechanism 3 is fixed on the frame 8, and the two pipe collecting mechanisms 3 on both sides are respectively arranged on the mobile workbench 4.

[0052] The process of receiving materials by the pipe receiving mechanism 3 is as follows: if it is a good product, the receiving cylinder 332 extends, and the good product guide plate 331 receives the pipe on the pipe conveying device 2. The pipe enters the good product receiving plate 31 through the good product guide plate 331, and the pipe 200 is restricted by the limiting part 311. When the good products are full, the good products can be moved away manually at one time; if it is a defective product, the receiving cylinder 332 retracts, and the pipe enters the U-shaped groove 321 of the defective product receiving rack 32 from the gap between the pipe conveying device 2 and the good product guide plate 331 and through the guidance of the defective product guide plate 322. When the defective products are full, the defective products can be moved away manually from the side at one time.

[0053] The first linear drive module 5 is driven by a servo motor, which accurately controls the distance of the movable table 4 to move left and right, thereby ensuring the accuracy of the sheath delivery. A pair of slide rails are arranged on the machine platform 8, and the movable table 4 is slidably arranged on the slide rails through a plurality of sliders.

A sheath feeding device 7 is correspondingly arranged on the side of each sheathing device 6, and the sheath feeding device 7 conveys the sheath 300 to the sheathing device 6.

[0055] In the present embodiment, four sheathing devices 6 are arranged on each mobile workbench 4, and the four sheathing devices 6 on the left side are opposite to and symmetrically arranged with the four sheathing devices 6 on the right side, and each sheathing device 6 wears a sheath, so that at most four sheaths 300 can be worn at each end of the pipe, and at most eight sheaths can be worn at both ends of the pipe, and one or more sheathing devices 6 can be selectively selected on each side to sheath the pipe, and after the last sheathing device 6 sheaths the pipe, the next sheathing device 6 is entered to continue sheathing the pipe, so that one or more sheaths 300 can be worn at each end of the pipe, and the length of each sheath can be different, and it can be cut according to the required sheath length, so that a plurality of sheaths of different lengths can be worn on the pipe, which has good versatility and high flexibility. In other embodiments, the number of sheathing devices 6 can be set according to actual conditions, and it is not limited here.

[0056] The sheath threading device 6 includes a conveying mechanism 61 for conveying the sheath 300, a cutting mechanism 62 for cutting the sheath 300, and a clamping mechanism 63 for clamping the sheath 300 and the tube 200, which are arranged in sequence along the sheath conveying direction.

A conveying gap for the sleeve to pass through is formed between the active synchronous belt group 611 and the driven synchronous belt group 612. A first guide cylinder 615 for the sleeve to pass through is provided on one side of the conveying gap, and a second guide cylinder 616 for the sleeve to pass through is provided on the other side. The first guide cylinder 615 and the second guide cylinder 616 can facilitate the insertion and exit of the sleeve, thereby facilitating the conveying of the sleeve.

[0058] The active synchronous belt group 611 and the driven synchronous belt group 612 have the same structure, both including synchronous wheels and synchronous belts, and a tensioning wheel for tensioning the synchronous belts is arranged between the synchronous wheels, which can ensure the tension between the upper and lower synchronous belts, so as to smoothly convey the sheath from the first guide cylinder 615 to the clamping mechanism 63. The driving assembly 614 can drive the driven synchronous belt group 612 to approach or move away from the active synchronous belt group 611, adjust the conveying gap between the driven synchronous belt group 612 and the active synchronous belt group 611, and convey pipes of different diameters, so as to adapt to pipes of different diameters.

The cutting cylinder 621 drives the cutting knife 622 to clamp and cut the sheath. In this embodiment, the sheath is a nylon tube made of plastic, and the cutting knife 622 can cut it directly.

[0062] An avoidance gap is provided in the second guide cylinder 616 for the cutting knife 622 to move up and down. The cutting knife 622 is arranged inside the second guide cylinder 616 to prevent the staff from being cut by the cutting knife 622 or to prevent the cutting knife 622 from cutting other objects.

[0063] The clamping mechanism 63 includes a second clamping assembly 631 for clamping the sheath and a third clamping assembly 632 for clamping the end of the pipe. The structures of the second clamping assembly 631 and the third clamping assembly 632 are the same as those of the first clamping assembly 26 and are not described again.

[0064] When the pipe sheathing device 100 provided by the present invention is used, a stack of pipes 200 is placed on the pipe storage bin 11, the first motor 12 drives the rotating shaft 13 to drive the turntable 14 to rotate, and the roller 18 at the lower end of the elastic hook assembly 17 rotates on the cam 15, so that the hook 171 extends out to hook the pipe, and the turntable 14 continues to rotate. The turntable 14 carries the pipe from the pipe storage bin 11 to the side of the pipe conveying device 2. When the pipe is rotated to a certain angle, the pipe will fall from the first card slot 16 due to gravity, and the fallen pipe is introduced into the conveying device 2 through the guide plate 24. The conveyor belt 22 is placed in the receiving block 23 at the front, and the blocking cylinder is extended to block the pipe, so that the pipe can enter the receiving block 23 smoothly.

The end of the pipe moves to the middle of the second clamping assembly 631 through the third clamping assembly 631. At the same time, the sheath on the sheath feeding device 7 enters the active The conveying gap between the synchronous belt group 611 and the driven synchronous belt group 612, the third motor 613 drives the active synchronous belt group 611 to convey the sheath to the right or left, the sheath enters the middle of the second clamping assembly 631 through the second guide cylinder 616, the sheath is connected to the pipe and sleeved on the outer periphery of the pipe 200, the third motor 613 drives the active synchronous belt group 611 to further convey the sheath, and the length measuring device 65 is used to measure the length of the conveyed sheath. After the sheath is conveyed to the set length, the second clamping assembly 631 and the third clamping assembly 632 respectively clamp the cutting The conveying mechanism 61 stops conveying the pipe and the sheath, and the cutting cylinder 621 of the cutting mechanism 62 drives the cutting knife 622 to cut the sheath, and the conveying mechanism 61 continues to convey, and the sheath conveyed on the conveying mechanism 61 is used to push the sheath just cut to the middle of the pipe to complete the sheath insertion. The left and right sheath insertion actions of the pipe 200 are consistent with those of the right sheath insertion device 6, and the left sheath insertion device 6 and the right sheath insertion device 6 work at the same time, and the sheath is inserted at both ends of the pipe at the same time. If only one end of the pipe needs to be sheathed, only the left or right sheath insertion device 6 can be used, which is very flexible.The sheath conveyed by the conveying mechanism 61 is used to push the sheath just cut toward the middle of the pipe, so as to expose the end of the pipe, so as to facilitate the next sheathing device 6 to continue to wear the next sheath at the end of the pipe. The action of wearing the next sheath is consistent with the above. After each end of the pipe 200 is well covered with a sheath, the second clamping assembly 631 and the third clamping assembly 632 release the pipe 200, and the second motor 21 drives the conveyor belt 22 to move backward to convey the sheathed pipe to the pipe receiving mechanism 3. If it is a good product, the receiving cylinder 332 extends. The good product guide plate 331 receives the pipes on the pipe conveying device 2, and the pipes enter the good product receiving plate 31 through the good product guide plate 331.
