Description

Technical Field

[0001] The invention relates to the technical field of plastic pipe palletizing, in particular to a palletizing device for producing plastic pipes. Background Art

[0002] In the production process of plastic pipes, in order to facilitate storage, transportation or management, the plastic pipes are palletized, that is, the produced plastic pipes are stacked together in a certain order and manner; when palletizing plastic pipes, most of them will first stack a number of plastic pipes on a pallet in sequence, and then use the support rods of the pallet to make the side of the stacked plastic pipes have a hexagonal structure. After the stacking is completed, the plastic pipes stacked in a hexagonal shape are bundled to facilitate the subsequent processing of the plastic pipes.

[0003] According to different usage environments, the pipes will be coated (anti-corrosion, flame retardant, etc.). In the process of stacking the coated pipes on the pallet in the above manner, the existing conveyor will be used to transport the pipes to the pallet one by one. The pipes fall onto the pallet under their own gravity and are stacked. At this time, friction will occur when the pipes fall (between two adjacent pipes or between the pipes and the pallet). The friction will damage the coating, thereby reducing the service life of the pipes. At the same time, in order to ensure the integrity of the coating, a robot will also be used for palletizing operations, but this method can only grab one pipe at a time, which is inefficient.

DETAILED DESCRIPTION

[0059] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0060] Example 1: A palletizing device for the production of plastic pipes, Figures 1 - 5 and Figure 9 As shown, it includes: a support frame 1, the support frame 1 is provided with a conveying module 2 and a receiving module 3; a dual-axis platform 4, which has two and is respectively installed on both sides of the support frame 1, and the dual-axis platform 4 is installed with a driving push rod 5, and the driving push rod 5 is provided with a clamping mechanism, and the clamping mechanism is used to clamp the to-be-clamped piece, and the clamping mechanism includes: a mounting seat 6, which is fixedly connected to the telescopic end of the driving push rod 5, and the mounting seat 6 is slidably connected to two clamping plates 7, and the mounting seat 6 is provided with a gravity driving mechanism for driving all the clamping plates 7 thereon to move; a mounting plate 8, which is fixedly connected to the mounting seat 6, and the mounting plate 8 is provided with a first through hole distributed in an array, and a partition mechanism is provided on the mounting plate 8, and the partition mechanism is used to separate the to-be-clamped pieces; an intercepting rod 9, which is arranged on the mounting plate 8.

[0061] In the above scheme, it is intended to solve the problem that the existing stacking method will damage the coating on the surface of the pipe and the stacking efficiency is low; the conveying module 2 is an existing transfer equipment, which is used to transfer the pipe to the position to be clamped, so as to facilitate the clamping of the pipe; the receiving module 3 is an existing pallet, which is used to limit the pipe placed on its upper side so that the side of the upper pipe forms a hexagonal structure; the double-axis platform 4 can move vertically and horizontally, that is, the double-axis platform 4 has horizontal slide rails and vertical slide rails; in this article, there are two clamping plates 7 sliding on each mounting seat 6, so as to realize the clamping of the pipe in a row; the diameter in the middle of the intercepting rod 9 is smaller than the diameter on both sides, that is, the intercepting rod 9 gradually tapers from both sides to the middle, so that the pipe located thereon rolls toward the middle; in this article, when clamping the pipe, the pipe is placed in the following way Figure 1 As shown; in this article, the clamp 7 clamps the end of the pipe, and the intercepting rod 9 contacts the end of the pipe, thereby reducing the probability of damage to the coating in the middle of the pipe (the two ends of the existing pipe are joints, and the joints are generally not coated).

[0062] Working principle: This article stacks the pipes in the order of four, five, six, five, and four from the top to the bottom, so that the side surfaces of the pipes form a hexagonal structure.

[0063] When stacking the pipes, four pipes are first placed on the conveying module 2. To avoid friction between two adjacent pipes, the pipes are placed separately (there is a gap between every two pipes). Then the conveying module 2 is turned on. The conveying module 2 works and drives the pipes thereon to move to the left until the pipes move to the bottom of the two mounting seats 6. The conveying module 2 stops working. The following description is made with reference to the rear dual-axis platform 4. Initially, the dual-axis platform 4 is located above the conveying module 2, that is, on the right side of the entire device.

[0064] After the pipe moves to the bottom of the mounting seat 6, the dual-axis platform 4 starts working and drives the driving push rod 5 thereon to move downward until the intercepting rod 9 completely passes through the pipe (the upper side of the intercepting rod 9 is lower than the lower side of the pipe), the dual-axis platform 4 stops working, and then the driving push rod 5 starts working and drives the mounting seat 6 to move forward until the intercepting rod 9 is located under the pipe, the driving push rod 5 stops working, the dual-axis platform 4 works again and drives the driving push rod 5 to move upward, thereby lifting the end of the pipe through the intercepting rod 9 (at this time the pipe is located between two adjacent clamps 7), and transporting the entire row of pipes, thereby improving the stacking efficiency. At the same time, the intercepting rod 9 contacts the end of the pipe to reduce the wear on the surface coating of the pipe.

[0065] During the upward movement of the intercepting rod 9, the gravity drive mechanism operates to cause the two clamping plates 7 to move relative to each other, squeezing the pipe so that the pipe moves towards the middle of the intercepting rod 9. During this process, the partitioning mechanism starts to operate to partition the pipe, keeping a distance between adjacent pipes at all times, preventing friction between adjacent pipes when the pipes move towards the middle of the intercepting rod 9, thereby reducing wear on the surface coating of the pipe.

[0066] After the double-axis platform 4 drives the drive push rod 5 to move upward to the limit position (the limit position refers to the upper side of the vertical slide rail of the double-axis platform 4), it starts to move leftward. The gravity drive mechanism and the partitioning mechanism are always in the working state, causing the two clamping plates 7 to slowly approach, and at the same time gradually reducing the distance between the pipes until all the pipes in the whole row are in contact with each other. After the double-axis platform 4 drives the drive push rod 5 to move to the limit position (that is, the drive push rod 5 is above the receiving module 3, and this limit position represents the left side of the horizontal slide rail of the double-axis platform 4), the double-axis platform 4 starts to drive the drive push rod 5 to move downward. During this process, the pipes start to move downward until the pipes move to contact the upper surface of the receiving module 3. The double-axis platform 4 drives the drive push rod 5 to continue moving, causing the intercepting rod 9 to disengage from the pipes. Subsequently, the double-axis platform 4 stops working, the telescopic end of the drive push rod 5 retracts and causes the intercepting rod 9 to move backward, thereby resetting the intercepting rod 9. Subsequently, the double-axis platform 4 drives the drive push rod 5 to return to the initial position according to the above-mentioned movement trajectory, and all the above-mentioned parts return to their original positions. Repeat the above steps to pick up and stack the second row of pipes (five). After repeating many times until the pipe stacking is completed.

[0067] Further, as shown in Figures 3 - 5 The gravity drive mechanism includes: a support member 21 fixedly connected to the mounting base 6; a counterweight 22 slidably connected to the support member 21; a drive rack 23 slidably connected to the mounting base 6 and in contact with the counterweight 22. A transmission shaft 24 is rotatably connected to the mounting base 6, and a drive gear 25 and a clamping gear 26 are fixedly connected to the transmission shaft 24. The drive gear 25 meshes with the drive rack 23, and a clamping rack 27 is fixedly connected to the clamping plate 7, and the clamping rack 27 meshes with the clamping gear 26; a limit push rod 28 is installed on the mounting base 6, and the telescopic end of the limit push rod 28 is used to limit the drive rack 23.

[0068] In the above solution, a method is proposed to move two adjacent clamping plates 7 towards each other to clamp the pipe. At the same time, it solves the problem that it is difficult to unify the clamping force of the existing automatic clamping equipment for clamping pipes with different quantities or different sizes. That is, when palletizing pipes of the same batch, regardless of the number of pipes between the two clamping plates 7, the force applied by the two clamping plates 7 to the pipes is constant, avoiding the force applied to the pipes gradually increasing as the number of clamped pipes increases, which may cause damage to the pipes. The support member 21 is provided with a chute for guiding the counterweight block 22. In the initial state, the counterweight block 22 is located at the uppermost side of the chute on the support member 21. The counterweight block 22 moves under the action of its own gravity to push the driving rack 23, and through transmission, two adjacent clamping plates 7 move towards each other. That is, the clamping force of the two clamping plates 7 on the pipes corresponds to the gravity of the counterweight block 22. The model of the counterweight block 22 can be replaced according to the models of different pipes. In the initial state, the telescopic end of the limit push rod 28 extends completely and contacts the driving rack 23. The clamping racks 27 on two adjacent clamping plates 7 are respectively located on the upper and lower sides of the adjacent clamping gears 26.

[0069] Working principle: During the process when the intercepting rod 9 is on the right side and moving upward, the limit push rod 28 starts to work. The telescopic end of the limit push rod 28 retracts and releases the limit on the driving rack 23. Subsequently, the counterweight block 22 slides along the support member 21 under its own gravity and squeezes the driving rack 23, causing the driving rack 23 to move to the right. The driving rack 23 drives the driving gear 25 to rotate. The driving gear 25 drives the clamping gear 26 to rotate through the transmission shaft 24. The clamping gear 26 drives the upper and lower clamping racks 27 to move. The clamping racks 27 drive the clamping plates 7 to move. In this way, two adjacent clamping plates 7 move towards each other and push the pipes between them towards the middle of the intercepting rod 9 until the pipes contact each other. Then, the two clamping plates 7 stop moving, the clamping racks 27 stop moving, the clamping gear 26 and the driving gear 25 stop rotating, the driving rack 23 stops moving, and the counterweight block 22 stops moving. At this time, the pipes are clamped by relying on the gravity of the counterweight block 22. The telescopic end of the limit push rod 28 continues to retract until it is completely retracted, and then the limit push rod 28 stops working.

[0070] After the limit push rod 28 stops working, the double-axis platform 4 drives the drive push rod 5 to continue moving leftward until the double-axis platform 4 drives the drive push rod 5 to move to the left side of its horizontal slide rail and then starts to move downward. After the pipe contacts the receiving module 3, the limit push rod 28 starts to work. The telescopic end of the limit push rod 28 extends until it contacts the drive rack 23. Then, the telescopic end of the limit push rod 28 pushes the drive rack 23 to move leftward. The clamping gear 26 and the drive gear 25 rotate in the opposite direction, and the clamping rack 27 moves in the opposite direction, causing the two clamping plates 7 to move away from each other and lose the clamping of the pipe. The drive rack 23 pushes the counterweight 22 in the opposite direction, causing the counterweight 22 to slide back to the uppermost side of the chute on the support member 21. Subsequently, the telescopic end of the drive push rod 5 retracts, and the above process is repeated for resetting.

[0071] Further, as shown in Figure 4 , Figure 6 , Figure 8 and Figure 9 , the partition mechanism includes: a limit plate 31, which is slidably connected to the mounting plate 8, and a first elastic member is fixedly connected between the two. The limit plate 31 is provided with second through holes distributed at intervals. The distance between two adjacent second through holes on the limit plate 31 is twice the distance between two adjacent first through holes on the mounting plate 8. The second through holes on the limit plate 31 communicate with the adjacent first through holes on the mounting plate 8; a fixed pipe 32, which is fixedly connected to the limit plate 31; a plurality of partition bags 33, which are all fixedly connected and communicated with the fixed pipe 32, and the partition bags 33 are slidably connected to both the limit plate 31 and the mounting plate 8; a trigger assembly, which is arranged on the mounting seat 6 and is used to inflate all the partition bags 33 on the same fixed pipe 32; a position-changing assembly, which is arranged on the mounting plate 8 and is used to change the sliding positions of the partition bags 33 and the limit plate 31; the projection of the partition bag 33 in the vertical direction is trapezoidal.

[0072] In the above solution, a method of partitioning between a whole row of pipes is proposed, so that the whole row of pipes do not contact each other, reducing the friction between the pipes, thereby reducing the wear on the surface coating of the pipes; the number of second through-holes on the limiting plate 31 is the same as the number of partition bags 33, and the second through-holes on the limiting plate 31 correspond to the positions between two adjacent pipes; the distance between two adjacent second through-holes on the limiting plate 31 is twice the distance between two adjacent first through-holes on the mounting plate 8; the first elastic member on the limiting plate 31 is a spring, which is used to drive the limiting plate 31 to reset; both sides of the partition bag 33 guide the contacting pipes, so that two adjacent pipes can move slowly; in this article, the number of first through-holes on the mounting plate 8 is nine, and the number of second through-holes on the limiting plate 31 is five. Initially, the second through-holes on the limiting plate 31 correspond to the first through-holes at odd positions on the mounting plate 8. After the limiting plate 31 moves under the action of the position-changing assembly, the second through-holes on the limiting plate 31 correspond to the first through-holes at even positions on the mounting plate 8, and the partition bag 33 at the right edge is blocked by the mounting plate 8 (that is, the partition bag 33 at the right edge is not used).

[0073] Working principle: During the process of the conveying module 2 driving the pipes thereon to move leftward, when the position of the gap between two adjacent pipes corresponds to the position of the second through-hole on the limiting plate 31, the conveying module 2 stops moving, that is, the partition bag 33 corresponds to the gap between two adjacent pipes. According to the above process, when the intercepting rod 9 is located below the pipes, the gaps between all the pipes respectively correspond to the adjacent partition bags 33.

[0074] During the process of the telescopic end of the limiting push rod 28 retracting, the triggering assembly starts to work and discharges gas into the fixed pipe 32. The gas in the fixed pipe 32 flows into all the partition bags 33, causing all the partition bags 33 to gradually expand. The expanded partition bags 33 enter the adjacent first through-holes on the mounting plate 8 along the adjacent second through-holes on the limiting plate 31, and protrude from the adjacent first through-holes on the mounting plate 8 and enter the space between two adjacent pipes. As the partition bags 33 gradually expand, two adjacent clamping plates 7 move towards each other. After both clamping plates 7 contact the pipes, all the pipes move towards the middle. At the same time, the expanded partition bags 33 isolate two adjacent pipes, preventing the two pipes from contacting and causing damage to the coating thereon. The pipes squeeze the partition bags 33, increasing the pressure inside them until the triggering assembly stops injecting gas into the partition bags 33 and slowly extracts the gas from all the partition bags 33. The two clamping plates 7 slowly squeeze the pipes, and the pipes slowly squeeze the partition bags 33, so that the distance between the pipes gradually decreases. As the gas in the partition bags 33 gradually decreases, the partition bags 33 slowly reset until they are completely out of contact with the mounting plate 8, and the telescopic end of the limiting push rod 28 is completely retracted. At this time, all the pipes are in contact with each other. After the partition bags 33 are reset, the triggering assembly stops working.

[0075] After the telescopic end of the limit push rod 28 is fully retracted, the double-axis platform 4 drives the drive push rod 5 to continue moving leftward, and the transposition assembly starts to work. The limit plate 31 stops moving, and the limit plate 31 moves relative to the mounting plate 8 and compresses the first elastic member of the limit plate 31. Until the double-axis platform 4 drives the drive push rod 5 to move rightward again, the limit plate 31 moves to the target position, and all the second through holes on the limit plate 31 respectively correspond to the first through holes at even positions on the mounting plate 8. The limit plate 31 drives the partition bladder 33 to move synchronously, so that all the partition bladders 33 respectively correspond to the first through holes at even positions on the mounting plate 8. By changing the positions of the first through holes on the mounting plate 8 corresponding to the limit plate 31 and the partition bladder 33, the position for clamping the next row of pipes is adapted, so that the position of the changed partition bladder 33 corresponds to the position when the subsequent pipes are placed. That is, after the first row of pipes is placed, the pipes in the second row should be respectively placed between two adjacent pipes in the first row (four pipes in the lower row and five pipes in the upper row, with the upper and lower pipes arranged staggered).

[0076] Further, as shown in Figure 4 、 Figure 6 and Figure 7 The trigger assembly includes: a transmission frame 34, fixedly connected to the telescopic end of the limit push rod 28; a drive plate 35, slidably connected to the mounting seat 6 and fixedly connected to the transmission frame 34, and the drive plate 35 is provided with a limit groove 351; a transmission telescopic rod 36, fixedly connected to the mounting seat 6, and the telescopic end of the transmission telescopic rod 36 is slidably located in the limit groove 351, and a one-way valve is installed on the fixed part of the transmission telescopic rod 36; an elastic tube 361, fixedly connected and communicated with the fixed part of the transmission telescopic rod 36 and communicated with the fixed tube 32.

[0077] In the above solution, a method for expanding all the partition bladders 33 is proposed. The transmission frame 34 is an L-shaped rod; the limit groove 351 is composed of two symmetric inclined grooves; the telescopic end of the transmission telescopic rod 36 is initially in a protruding state, and its fixed part is filled with gas; the elastic tube 361 can be stretched; when the telescopic end of the transmission telescopic rod 36 moves upward, the one-way valve on the transmission telescopic rod 36 opens, allowing external gas to enter the transmission telescopic rod 36. When the telescopic end of the transmission telescopic rod 36 moves downward, the one-way valve on it closes.

[0078] Working principle: When the telescopic end of the limit push rod 28 is retracted, the telescopic end of the limit push rod 28 drives the transmission frame 34 to move rightward, the transmission frame 34 drives the drive plate 35 to move rightward, the drive plate 35 drives the limit groove 351 on it to move rightward, the limit groove 351 squeezes the telescopic end of the transmission telescopic rod 36, the telescopic end of the transmission telescopic rod 36 retracts and compresses the gas in its fixed part, and the gas in the fixed part of the transmission telescopic rod 36 enters the fixed tube 32 along the elastic tube 361, and then all the partition bladders 33 expand.

[0079] During the process of the limiting groove 351 moving to the right, when the telescopic end of the transmission telescopic rod 36 moves to the lowermost side of the limiting groove 351, the inflation of the partition bladder 33 is stopped. At this time, the pipe has come into contact with the partition bladder 33. As the limiting groove 351 moves, the limiting groove 351 drives the telescopic end of the transmission telescopic rod 36 to move upward and creates a negative pressure in the fixed part of the transmission telescopic rod 36. Subsequently, the fixed part of the transmission telescopic rod 36 sucks back all the gas in the partition bladders 33 until the telescopic end of the limiting push rod 28 fully extends, causing all the partition bladders 33 to return to their original shapes. At this time, all the pipes are in contact with each other.

[0080] Further, as shown in Figure 4 and Figures 10 - 13 The transposition assembly includes: a swing rod 41 rotatably connected to the mounting plate 8; a fixed plate 42 fixedly connected to the limiting plate 31. The fixed plate 42 is provided with a transposition groove 421, and the swing rod 41 is slidably located in the transposition groove 421; a push rod 43 fixedly connected to the side of the limiting plate 31 away from the swing rod 41; a blocking plate 44 fixedly connected to the support frame 1 for limiting the push rod 43.

[0081] In the above solution, a method for changing the position of the partition bladder 33 is provided, so that each time a whole row of pipes is placed, the upper pipes and the lower pipes are staggered; the transposition groove 421 is composed of a first positioning groove 4211, a first sliding groove 4212, a second sliding groove 4213, a second positioning groove 4214, a third sliding groove 4215, and a fourth sliding groove 4216. The swing rod 41 is limited by the first positioning groove 4211 and the second positioning groove 4214 to fix the limiting plate 3; the distance between the first positioning groove 4211 and the second positioning groove 4214 is equal to the distance between the first through hole on the mounting plate 8 and the adjacent and misaligned second through hole on the limiting plate 31; the groove depths of the first positioning groove 4211 and the first sliding groove 4212 gradually decrease from left to right, the groove depth of the first sliding groove 4212 is less than the groove depth of the second sliding groove 4213, and the groove depths of the second sliding groove 4213, the second positioning groove 4214, the third sliding groove 4215, and the fourth sliding groove 4216 gradually decrease from the second sliding groove 4213 to the fourth sliding groove 4216; the left side of the second positioning groove 4214 is higher than the right side of the second positioning groove 4214 in the vertical direction.

[0082] Working principle: After all the pipes are in contact with each other (the telescopic end of the limit push rod 28 is fully retracted), the dual-axis platform 4 drives all the parts on it to move leftward synchronously, the push rod 43 moves leftward. When the push rod 43 contacts the blocking plate 44, the push rod 43 stops moving, the limit plate 31 stops moving, that is, the fixed plate 42 stops moving. The dual-axis platform 4 drives the mounting plate 8 to continue moving leftward, and the mounting plate 8 drives the swing rod 41 to continue moving leftward. At this time, the limit plate 31 and the mounting plate 8 move relative to each other, and the first elastic member of the limit plate 31 is compressed. The fixed plate 42 and the swing rod 41 move relative to each other. During this process, the swing rod 41 moves out of the first positioning groove 4211 and enters the first sliding groove 4212. As the swing rod 41 continues to move, the swing rod 41 enters the second sliding groove 4213. At this time, the dual-axis platform 4 drives the driving push rod 5 to stop moving leftward, that is, the driving push rod 5 is located on the left side of the horizontal slide rail of the dual-axis platform 4. Subsequently, the dual-axis platform 4 drives the driving push rod 5 to start moving downward. At this time, the first elastic member of the limit plate 31 is in a compressed state, and the swing rod 41 is located in the second sliding groove 4213.

[0083] After the pipes are placed, the dual-axis platform 4 drives the driving push rod 5 to move upward to the upper side of its vertical slide rail. Subsequently, the dual-axis platform 4 drives the driving push rod 5 to start moving rightward. During this process, the dual-axis platform 4 drives the mounting plate 8 to move rightward. The push rod 43 remains in contact with the blocking plate 44 under the action of the first elastic member of the limit plate 31. After the push rod 43 loses contact with the blocking plate 44, the limit plate 31 moves relative to the mounting plate 8 under the action of the first elastic member on it. During this process, the mounting plate 8 drives the swing rod 41 to move rightward. The swing rod 41 moves out of the second sliding groove 4213 and enters the second positioning groove 4214. At this time, the second positioning groove 4214 limits the swing rod 41, so that the swing rod 41 drives the fixed plate 42 to move rightward synchronously. During this process, the limit plate 31 completes its movement relative to the mounting plate 8, and aligns the second through hole of the limit plate 31 with the first through hole at the even position of the mounting plate 8, thereby completing the transposition of the limit plate 31 and the partition bladder 33.

[0084] During the above process, the push rod 43 and the blocking plate 44 are squeezed for the first time, and the swing rod 41 moves from the first positioning groove 4211 to the second positioning groove 4214. After the push rod 43 and the blocking plate 44 are squeezed for the second time, the swing rod 41 moves from the second positioning groove 4214 to the first positioning groove 4211 (the swing rod 41 moves out of the second positioning groove 4214, passes through the third sliding groove 4215 and the fourth sliding groove 4216, and finally enters the first positioning groove 4211), and so on.

[0085] Further, compare Figure 6 and Figure 7As shown in the figure, it further includes: a partition plate 37, having two pairs, and the two pairs of partition plates 37 are respectively slidably connected in adjacent fixed pipes 32, and the elastic tube 361 is located between an adjacent pair of partition plates 37; it further includes: a pressure relief valve 38, having two, which are respectively installed on adjacent fixed pipes 32, and the pressure relief valve 38 is located between an adjacent pair of partition plates 37.

[0086] In the above solution, each pair of partition plates 37 is symmetrically distributed, and the communication position between the elastic tube 361 and the fixed pipe 32 is located between two adjacent partition plates 37. A damping is provided at the sliding connection between the partition plate 37 and the fixed pipe 32; the pressure relief valve 38 is used to ensure the constant pressure in the fixed pipe 32 and the partition capsule 33.

[0087] Working principle: During the process of injecting gas from the elastic tube 361 into the fixed pipe 32, after the gas enters the fixed pipe 32, under the blocking action of the two partition plates 37, it can only pump gas into the middle partition capsule 33, that is, the middle partition capsule 33 is preferentially inflated. Until the middle partition capsule 33 is fully inflated, the pressure in the fixed pipe 32 increases, and the two partition plates 37 are pushed, causing the two partition plates 37 to move away from each other. Until the two partition plates 37 pass after the second partition capsule 33 and the fixed pipe 32 (counting from the middle to both sides), the gas in the fixed pipe 32 is discharged into the second partition capsule 33, and the two partition plates 37 stop moving. Repeat this process, and the partition capsules 33 are inflated in sequence from the middle to both sides.

[0088] When the transmission telescopic rod 36 extracts the gas in the fixed pipe 32, the two partition plates 37 move towards each other, so that the partition capsules 33 on both sides are fully contracted (from both sides to the middle). After the outer partition capsule 33 contracts, the two adjacent pipes are attached to each other, so that the whole row of pipes gradually fits from the outside to the inside, preventing the loss of isolation of the whole row of pipes after all the partition capsules 33 contract synchronously, leaving gaps between the whole row of pipes, resulting in collisions when the pipes move towards each other.

[0089] During the process of injecting gas into the partition capsule 33, if the partition capsule 33 is squeezed by the pipe, at this time the pressure in the partition capsule 33 gradually increases. If the pressure reaches the threshold of the pressure relief valve 38, the pressure relief valve 38 opens and releases the gas in the fixed pipe 32 to reduce the pressure in the whole fixed pipe 32 and prevent damage to the parts due to excessive internal pressure.

[0090] When placing the second row of pipes, since the intercepting rod 9 bears the second row of pipes, and the intercepting rod 9 is located above the first row of pipes. When the intercepting rod 9 moves down to contact the first row of pipes, it stops moving down and moves to both sides under the action of the driving push rod 5. The two intercepting rods 9 have relative friction with both the first row of pipes and the second row of pipes, which will cause damage to the coatings on the surfaces of the first row of pipes and the second row of pipes. To solve this problem, the following method is proposed:

[0091] Example 2: On the basis of Example 1, for comparison Figure 4 , Figure 9 , Figure 11 and Figure 14 as shown, it further includes: a protection mechanism, having two, respectively arranged on adjacent mounting plates 8, for protecting the object to be clamped. The protection mechanism includes: a detection rod 51, slidably connected to the mounting plate 8, and a second elastic member is arranged between the two. A rubber sleeve is arranged on the outer side of the detection rod 51. The second elastic member is a spring, used to drive the detection rod 51 to reset. An arc-shaped groove is arranged on the mounting plate 8, and the detection rod 51 slides along the arc-shaped groove. A clamping plate 511 is fixedly connected to the detection rod 51, and the clamping plate 511 is a rubber block; an extrusion rod 52, rotatably connected to the mounting plate 8, and a rubber sleeve is also sleeved on the outer side of the extrusion rod 52. The above two rubber sleeves are both used to increase the friction between the extrusion rod 52 and the detection rod 51 and the pipe, and at the same time buffer the extrusion force on the pipe, reducing the wear on the pipe. The mounting plate 8 is rotatably connected to the intercepting rod 9. A first gear 53 is fixedly connected to the intercepting rod 9, and a second gear 54 is fixedly connected to the extrusion rod 52. The rotation center of the extrusion rod 52 is located in front of the center of the arc-shaped groove (taking the parts on the rear mounting plate 8 as an example here). The first gear 53 meshes with the second gear 54, and the clamping plate 511 is used to limit the second gear 54.

[0092] Working principle: Taking the placement of the second row of pipes (five) as an example, when the double-axis platform 4 drives the driving push rod 5 to slide downward, the mounting plate 8 drives the detection rod 51 to move downward. When the detection rod 51 contacts the first layer of pipes (four), the detection rod 51 stops moving downward. The mounting plate 8 continues to move downward, and the detection rod 51 slides along the arc-shaped groove of the mounting plate 8 (the second elastic member of the detection rod 51 is compressed). The detection rod 51 drives the clamping plate 511 to move, and the clamping plate 511 loses contact with the second gear 54, and the clamping plate 511 loses the limit on the second gear 54. As the mounting plate 8 moves downward, after the extrusion rod 52 contacts the first layer of pipes, the mounting plate 8 stops moving downward, and the two driving push rods 5 are controlled to move the two mounting plates 8 away from each other. Taking the rear parts as an example, the mounting plate 8 drives the extrusion rod 52 to move backward, and the extrusion rod 52 rotates along the first layer of pipes. The extrusion rod 52 drives the second gear 54 to rotate, and the second gear 54 drives the intercepting rod 9 to rotate through the first gear 53. During the backward movement of the rear intercepting rod 9, it rotates along the second layer of pipes, thereby reducing the wear on the surface coating of the second layer of pipes. At the same time, when the extrusion rod 52 rotates along the first layer of pipes, the surface coating of the first layer of pipes will not be damaged either.
