Description

TECHNICAL FIELD

[0002] In the medical and automotive industries, some straight pipe products (such as distribution straight pipes for fuel pipe processing) are involved. Before the delivery of the straight pipe, we need to clean the pipe according to the customer's requirements to remove the stains on the inner long hole wall of the pipe. At present, we generally use manual cleaning method, that is, the operator inserts the cleaning cloth into the inner long hole of the pipe from one end of the pipe, and then pulls out the cleaning cloth from the other end of the pipe after the cleaning cloth passes through the inner long hole of the pipe. The cleaning cloth slides along the inner wall of the pipe during the pulling-out process, thereby removing the stains adhered to the inner long hole wall of the pipe.

[0003] However, the above-mentioned manual cleaning method has relatively low efficiency, and the cleaning effect depends on the operation method and habit of each operator, resulting in uncertainty of the cleaning effect, which may not achieve the same or similar cleaning effect for all batches of products delivered.

Meanwhile, the front part of the left through hole one 3111, the front part of the left through hole two, the front part of the left through hole three, the front part of the left through hole four, the front part of the left through hole five, the front part of the left through hole six, the front part of the right through hole one, the front part of the right through hole two, the front part of the right through hole three, the front part of the right through hole four, the front part of the right through hole five and the front part of the right through hole six are respectively provided with an internal shoulder.

[0093] We take the left tightening end one 311 as an example to illustrate the structure of the tightening end. As shown in Figure 8 the left end of the pipe A is inserted into the front end of the left through hole one 3111, and is stopped by the end face of the internal shoulder one 3112.

[0094] In this embodiment, the left clamping end 1 311, left clamping end 2 312, left clamping end 313, left clamping end 411, left clamping end 5 412, and left clamping end 6 413 are distributed sequentially from front to back. Simultaneously, the left through hole 1 3111 and the right through hole 1 are on the same straight line; the left through hole 2 and the right through hole 2 are on the same straight line; the left through hole 3 and the right through hole 3 are on the same straight line; the left through hole 4 and the right through hole 4 are on the same straight line; the left through hole 5 and the right through hole 5 are on the same straight line; and the left through hole 6 and the right through hole 6 are on the same straight line. Furthermore, the distance between the left through hole 1 3111 and the left through hole 4, the distance between the left through hole 2 and the left through hole 5, and the distance between the left through hole 3 and the right through hole 6 are all equal to the distance between the first clamping groove 201 and the second clamping groove 202.

[0095] During operation, the first cleaning rod 317 can enter the left through hole 2 inside the left clamping end 312 under the drive of the left gripper cylinder 315, and then enter the inner elongated hole of the tube located in the first clamping groove 201 from left to right; after entering the inner elongated hole of the tube, the first cleaning rod 317 will rub against the corresponding inner elongated hole wall of the tube during the movement, and perform cleaning rod cleaning operation to peel off the dust and other stains on the inner wall of the tube.

[0096] Similarly, the second cleaning rod 417 can enter the left through hole 5 inside the left clamping end 5 412 under the drive of the left gripper cylinder 2 415, and then enter the inner elongated hole of the tube located in the second clamping groove 202 from left to right; after entering the inner elongated hole of the tube, the second cleaning rod 417 will rub against the corresponding inner elongated hole wall of the tube during the movement, and perform the cleaning rod cleaning operation to peel off the dust and other stains on the inner wall of the tube.

[0097] In this embodiment, the left through hole 3111 in the left tightening end 311, the left through hole 3 in the left tightening end 313, the left through hole 4 in the left tightening end 411, and the left through hole 6 in the left tightening end 613 are respectively connected to the air intake pipe. During the cleaning process, high-pressure gas can be blown into the elongated hole inside the pipe from left to right through the left through hole 3111, left through hole 3, left through hole 4, and left through hole 6, and flow out from the right through hole 1, right through hole 3, right through hole 4, and right through hole 6 respectively, while simultaneously carrying out dust and other dirt from the corresponding elongated holes inside the pipe.

[0098] In the embodiment, two material clamping grooves, i.e. the first material clamping groove 201 and the second material clamping groove 202, are arranged; each material clamping groove is equipped with a set of cleaning mechanisms, i.e. the first cleaning mechanism and the second cleaning mechanism, and the first cleaning mechanism and the second cleaning mechanism are identical in structure. The first cleaning mechanism is used to perform the blowing cleaning and the cleaning rod cleaning operation on the pipe material entering the first material clamping groove 201, and the second cleaning mechanism is used to perform the blowing cleaning and the cleaning rod cleaning operation on the pipe material entering the second material clamping groove 202. The carrier disc 200 moves forward and backward under the driving of the servo motor 240, thereby driving the first material clamping groove 201 and the second material clamping groove 202 to move forward and backward.

[0099] Of course, in addition to the matching scheme of the two material clamping grooves and the two sets of cleaning mechanisms mentioned in the embodiment, we can also choose to arrange one material clamping groove and one set of cleaning mechanisms on the carrier disc 200 to form a pipe material inner long hole cleaning device, which can also realize the blowing cleaning and the cleaning rod cleaning operation on the pipe material.

[0100] During the cleaning process, the pipe material can be subjected to the blowing cleaning operation, the cleaning rod cleaning operation and the second blowing cleaning operation in sequence through the cooperation of the first cleaning assembly 31 and the first material ejecting assembly 32. The brief operation steps are as follows:

[0101] (1) First, the pipe material is placed in the first material clamping groove 201.

[0102] (2) Then, the carrier disc 200 moves; when the first material clamping groove 201 is located between the left through hole three and the right through hole three, the carrier disc 200 stops moving; the left clamping end three 313 and the right clamping end three 323 move to the center under the driving of the left moving air cylinder one 314 and the right moving air cylinder one 324, respectively, and tightly lock the pipe material between the left through hole three and the right through hole three; then, the high-pressure gas enters the inner long hole of the pipe material from the left through hole three and flows out from the right through hole three, and carries away the dust and stains in the hole of the pipe material, thereby completing the first blowing cleaning operation on the pipe material.

[0103] (3), then, the left end three 313 and right end three 323 reset movement, the disc 200 continues to move; the first material groove 201 moves to the left between the hole two and right hole two, the disc 200 stops moving, the left end two 312 and right end two 322 in the left moving cylinder one 314 and right moving cylinder one 324 drive under the center movement, the pipe material both ends are locked between the left hole two and right hole two, then, the left jaw cylinder one 315 clamps the first cleaning rod 317, the left push cylinder one 316 drives the left jaw cylinder one 315 to move to the left block one 310 direction, thereby driving the first cleaning rod 317 forward, then, the left jaw cylinder one 315 loosens the first cleaning rod 317, the left push cylinder one 316 drives the left jaw cylinder one 315 to move back, after resetting, the left jaw cylinder one 315 clamps the first cleaning rod 317 again, the left push cylinder one 316 drives the left jaw cylinder one 315 to move to the left block one 310 direction again, so on and so forth, until the first cleaning rod 317 is sent into the pipe material inner hole through the left hole two. After entering the pipe material inner hole, the first cleaning rod 317 will rub with the corresponding pipe material inner hole wall during the movement, and the cleaning rod cleaning operation is carried out.

[0104] (4), after cleaning, reverse operation makes the first cleaning rod 317 exit the pipe material inner hole, and the left end two 312 and right end two 322 reset movement after the first cleaning rod 317 exits.

[0105] In the process of the first cleaning rod 317 entering and exiting the pipe material inner hole, since the first cleaning rod 317 penetrates in the two positioning holes one 3181, when the left jaw cylinder one 315 loosens the first cleaning rod 317, the relative position of the first cleaning rod 317 will be locked by the positioning hole one 3181, and the first cleaning rod 317 will not roll down due to loosening of the left jaw cylinder one 315.

[0106] (5), then, the disc continues to move; the first material groove 201 continues to move to the left hole one 3111 and right hole one, the disc 200 stops moving, the left end one 311 and right end one 321 respectively in the left moving cylinder one 314 and right moving cylinder one 324 drive under the center movement, the pipe material both ends are locked between the left hole one 3111 and right hole one, then, the high pressure gas enters the pipe material inner hole from the left hole one 3111 and flows out from the right hole one, and carries away the dust and stains in the pipe hole, and the second blowing cleaning operation of the pipe material is completed. After cleaning, the left end one 311 and right end one 321 reset movement.

[0107] (6), after the pipe material is taken out from the first material groove 201, the second pipe material is placed in the first material groove 201.

[0108] (7), repeat steps (2) to (6).

[0109] To better facilitate the loading of pipes onto the carrier 200, in this embodiment, a feeding mechanism 1 is added above the carrier 200, such as... Figures 10-15 As shown. The feeding mechanism 1 includes a storage bin 100, and a rectangular storage bin outlet 101 is provided at the lower end of the storage bin 100; a feeding cylinder 120 for pipes to pass through is provided below the storage bin outlet 101, a feeding cylinder receiving port 123 is provided at the upper end of the feeding cylinder 120, and a feeding cylinder outlet 122 is provided at the lower end of the feeding cylinder 120.

[0110] In this embodiment, the discharge port 122 of the barrel faces directly downwards. The discharge port 122 is located above the carrier plate 200 and between the left tightening end 313 and the left tightening end 411.

[0111] Preferably, the interior of the storage silo 100 is provided with at least one inclined inner wall for guiding the pipe to roll down toward the storage silo outlet 101, the inclined inner wall extending inclinedly toward the storage silo outlet 101. Figure 10 and Figure 11 As shown, in this embodiment, there are two inclined inner walls, namely the front inner wall and the rear inner wall of the storage silo 100; these two inclined inner walls are symmetrically distributed and inclined downwards in the center. After the pipe enters the storage silo 100, it can move towards the discharge port 101 of the storage silo under the guidance of the two inclined inner walls.

[0112] like Figure 10 and Figure 11 As shown, a stepping feed rod 110 is provided between the storage bin outlet 101 and the material cylinder inlet 123 to transfer the pipe falling from the storage bin outlet 101 to the feed cylinder 120. The stepping feed rod 110 is a cylinder. The distance between the outer wall of the stepping feed rod 110 and the storage bin outlet 101, as well as the distance between the outer wall of the stepping feed rod 110 and the material cylinder inlet 123, are both smaller than the diameter of the pipe.

[0113] In this embodiment, the stepping feed rod 110 extends laterally; and the stepping feed rod 110 is close to the discharge port 101 of the storage bin, with the right side of the stepping feed rod 110 close to the material inlet 123 of the material cylinder; the upper end of the material inlet 123 is above the stepping feed rod 110, and the lower end of the material inlet 123 is below the stepping feed rod 110, thus causing the material inlet 123 to surround part of the side wall of the stepping feed rod 110. In this way, when the pipe falls from the stepping feed rod 110 into the feed cylinder 120, better protection is provided, preventing the pipe from falling out of the material inlet 123 during the fall.

[0114] Preferably, the outer wall of the step-down feeding rod 110 is provided with three side wall grooves 111 along the axial direction for accommodating the pipes falling from the discharge port 101 of the storage bin; one end of the step-down feeding rod 110 is further provided with a feeding rod driving component for driving the rotation of the step-down feeding rod 110.

[0115] In the embodiment, the side wall grooves 111 extend along the axial direction, and when the side wall grooves 111 are directly below the discharge port 101 of the storage bin during the rotation of the step-down feeding rod 110, the pipes will fall from the discharge port 101 of the storage bin into the side wall grooves 111 below. In the embodiment, the pipes falling into the side wall grooves 111 are placed in the side wall grooves 111 as a whole; then the step-down feeding rod 110 continues to rotate, and the side wall grooves 111 move away from the directly below of the discharge port 101 of the storage bin. In the embodiment, the step-down feeding rod 110 and the discharge port 101 of the storage bin are close to each other, and the space between the step-down feeding rod 110 and the discharge port 101 of the storage bin is very small. At this time, until the second subsequent side wall groove 111 is turned to the below of the discharge port 101 of the storage bin, the second subsequent pipe cannot completely fall out of the discharge port 101 of the storage bin. In this way, the pipes can only fall into the side wall grooves 111 from the discharge port 101 of the storage bin, and approach the receiving port 123 of the material cylinder along with the rotation of the step-down feeding rod 110. When the slot of the side wall groove 111 gradually faces downward, the pipes fall into the feeding channel 121 provided in the feeding cylinder 120 from the receiving port 123 of the material cylinder under the action of gravity, and finally fall downward from the discharge port 122 of the material cylinder.

[0116] In the embodiment, the feeding rod driving component includes a connecting shaft connected with the step-down feeding rod 110, a driven pulley 133 connected with the connecting shaft, a driving pulley 132, a step motor 131 for driving the rotation of the driving pulley 132, and a transmission synchronous belt 130 for connecting the driving pulley 132 and the driven pulley 133.

[0117] During operation, the stepper motor 131 drives the active rotating wheel 132 to rotate, which in turn drives the passive rotating wheel 133 to rotate synchronously. The passive rotating wheel 133 drives the connecting shaft to rotate, and the connecting shaft drives the stepper feed rod 110 to rotate. During the rotation of the stepping feed rod 110, when the side wall groove 111 is directly below the discharge port 101 of the storage bin, the pipe will fall from the discharge port 101 of the storage bin into the corresponding side wall groove 111. Then, the side wall groove 111 carries the pipe towards the material receiving port 123 of the cylinder. As the groove opening of the side wall groove 111 gradually faces downward, the pipe will fall from the side wall groove 111, enter the feed cylinder 120 from the material receiving port 123, and finally fall out from the discharge port 122 of the cylinder. When the second clamping groove 202 or the first clamping groove 201 is directly below the discharge port 122 of the cylinder, the pipe will fall into the second clamping groove 202 or the first clamping groove 201, thereby realizing the feeding operation of the pipe entering the second clamping groove 202 or the first clamping groove 201.

[0118] In this embodiment, the three side wall grooves 111 are evenly distributed along the outer circumference of the stepping feeding rod 110. The rotation of the stepping feeding rod 110 can enable the pipe to be fed from the storage bin outlet 101 into the feeding cylinder 120 sequentially and at intervals, thereby better controlling the rhythm of the feeding operation.

[0119] Preferably, a number of perforations 102 are distributed longitudinally on the side wall of the storage silo 100; through the perforations 102, the height of the pipes stacked inside the storage silo 100 can be observed and understood from the outside, and when there are not many pipes left in the storage silo, pipes can be added to the storage silo in time.

[0120] Using this pipe internal long hole cleaning system, the cleaning operation of the pipe internal long hole can be carried out continuously, performing air-blowing cleaning, cleaning rod cleaning, and air-blowing cleaning again on each pipe. The specific steps are as follows:

[0121] Step (1): Connect the rear ends of left through hole 1 3111, left through hole 3, left through hole 4 and left through hole 6 to the air intake device; put several pipes into the storage bin; start the feeding rod drive component, the step feeding rod 110 rotates, and the carrier plate 200 drives the first material clamping groove 201 to move towards the material cylinder outlet 122.

[0122] Step (2): The first material clamping groove 201 is moved to the position directly below the material cylinder outlet 122, the carrier plate 200 stops moving, and the pipe falls from the material cylinder outlet 122 into the first material clamping groove 201.

[0123] Step (3): the carrier disc 200 continues to move to the front side; when the first material clamping groove 201 moves between the left through hole three and the right through hole three, the carrier disc 200 stops moving, the left clamping end three 313 and the right clamping end three 323 are moved in alignment, the pipe material in the first material clamping groove 201 is locked between the left through hole three and the right through hole three, then the gas is blown into the long hole of the pipe material from the left through hole three and flows out from the right through hole three, the first gas blowing and cleaning is performed on the pipe material in the first material clamping groove 201, and the pipe material is preliminarily cleaned.

[0124] Step (4): the left clamping end three 313 and the right clamping end three 323 are reversely reset, and the carrier disc 200 continues to move to the front side; when the first material clamping groove 201 moves between the left through hole two and the right through hole two, the carrier disc 200 stops moving, the left clamping end two 312 and the right clamping end two 322 are moved in alignment, the pipe material in the first material clamping groove 201 is locked between the left through hole two and the right through hole two, and then the first cleaning rod 317 is sent into the long hole of the pipe material to perform the cleaning rod cleaning operation on the inner wall of the pipe material.

[0125] Step (5): the first cleaning rod 317 exits the long hole of the pipe material, the left clamping end two 312 and the right clamping end two 322 are reset and moved, then the carrier disc 200 continues to move to the front side, when the first material clamping groove 201 moves between the left through hole one 3111 and the right through hole one, the carrier disc 200 stops moving, the left clamping end one 311 and the right clamping end one 321 are moved in alignment, the pipe material in the first material clamping groove 201 is locked between the left through hole one 3111 and the right through hole one, then the gas is blown into the long hole of the pipe material from the left through hole one 3111 and flows out from the right through hole one, and the second gas blowing and cleaning operation is performed on the pipe material in the first material clamping groove 201.

[0126] Step (6): the left clamping end one 311 and the right clamping end one 321 are reset, and the carrier disc 200 continues to move to the front side; when the second material clamping groove 202 moves directly below the barrel discharge port 122, the carrier disc 200 stops moving, the second pipe material falls into the second material clamping groove 202 from the barrel discharge port 122, and the material pressing and discharging assembly one 21 takes out the pipe material from the first material clamping groove 201 and discharges the pipe material into the front side regular box 5.

[0127] Step (7): the carrier disc 200 continues to move to the rear side; when the second material clamping groove 202 moves between the left through hole four and the right through hole four, the carrier disc 200 stops moving, the left clamping end four 411 and the right clamping end four 421 are moved in alignment, and the pipe material in the second material clamping groove 202 is locked between the left through hole four and the right through hole four; then the gas is blown into the long hole of the pipe material from the left through hole four and flows out from the right through hole four, and the first gas blowing and cleaning is performed on the pipe material in the second material clamping groove 202.

[0128] Step (8): The left and right clamping ends four 411, 421 are reset, and the carrier plate 200 continues to move to the rear side. When the second clamping groove 202 moves between the left and right through holes five, the carrier plate 200 stops moving, the left and right clamping ends five 412, 422 are centered and moved, and the pipe in the second clamping groove 202 is locked between the left and right through holes five. Then, the second cleaning rod 417 is sent into the long hole in the pipe in the second clamping groove 202 to clean the inner wall of the pipe.

[0129] Step (9): The second cleaning rod 417 is withdrawn from the long hole in the pipe, and the left and right clamping ends five 412, 422 are reset. Then, the carrier plate 200 continues to move to the rear side. When the second clamping groove 202 moves between the left and right through holes six, the carrier plate 200 stops moving, the left and right clamping ends six 413, 423 are centered and moved, and the pipe in the second clamping groove 202 is locked between the left and right through holes six. Then, gas is blown into the long hole in the pipe from the left through hole six and flows out from the right through hole six to perform a second gas cleaning on the pipe in the second clamping groove 202.

[0130] Step (10): The left and right clamping ends six 413, 423 are reset, and the carrier plate 200 continues to move to the rear side. When the first clamping groove 201 moves again to directly below the barrel discharge port 122, the carrier plate 200 stops moving, and the third pipe falls into the first clamping groove 201 from the barrel discharge port 122, and the pipe in the second clamping groove 202 is taken out by the pressing and discharging assembly two 22 and unloaded into the rear regular box 6.

[0131] Step (11): Repeat steps (3) to (10) above.

[0132] In the above operation process, the pipe material is dropped into the first material clamping groove 201 and the second material clamping groove 202 in turn and at intervals. When the first material clamping groove 201 is located directly below the material outlet 122 of the material cylinder, the second material clamping groove 202 carrying the pipe material is moved to the side close to the rear side of the sorting box 6, at this time, the loading operation of the first material clamping groove 201 (i.e. the pipe material is dropped into the first material clamping groove 201 from the material outlet 122 of the material cylinder) and the unloading operation of the pipe material in the second material clamping groove 202 (i.e. the pipe material in the second material clamping groove 202 is unloaded into the rear side of the sorting box 6 by the second material unloading assembly 22) can be carried out synchronously; similarly, when the second material clamping groove 202 is located directly below the material outlet 122 of the material cylinder, the first material clamping groove 201 carrying the pipe material is moved to the side close to the front side of the sorting box 5, at this time, the loading operation of the second material clamping groove 202 (i.e. the pipe material is dropped into the second material clamping groove 202 from the material outlet 122 of the material cylinder) and the unloading operation of the pipe material in the first material clamping groove 201 (i.e. the pipe material in the first material clamping groove 201 is unloaded into the front side of the sorting box 5 by the first material unloading assembly 21) can be carried out synchronously. In this way, the pipe material loading operation and the pipe material unloading operation can be better connected; and during the movement of the carrying disc 200 back and forth, the loading, air blowing cleaning, cleaning rod cleaning and unloading operations of several pipe materials are continuously completed.

[0133] In the above cleaning operation process, whenever the pipe material is dropped into the first material clamping groove 201 from the material outlet 122 of the material cylinder, the material unloading clamp cylinder 1 210 clamps the pipe material in the first material clamping groove 201 to prevent it from moving during the cleaning process; whenever the pipe material is dropped into the second material clamping groove 202 from the material outlet 122 of the material cylinder, the material unloading clamp cylinder 2 220 clamps the pipe material in the second material clamping groove 202 to prevent it from moving during the cleaning process.

[0134] In the above entire cleaning operation process, the inner long hole of each pipe material will go through the first air blowing cleaning, cleaning rod cleaning and second air blowing cleaning three cleaning steps, which can clean the inner long hole of the pipe material more thoroughly and efficiently and cleanly compared with manual cleaning.
