Description

Technical Field

[0001] This invention relates to the field of pipeline production technology, specifically to an automated three-dimensional warehouse storage and retrieval production line and production process for pipelines. Background Technology

[0002] During processing, pipes are cut into sections by a cutting process and then conveyed to a grinding process via a conveyor belt for end grinding. This process typically means that a single production line can only process pipes of one diameter.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 Please see Figure 1-9 This invention provides a technical solution: an automated three-dimensional warehouse storage and retrieval production line for pipelines, comprising: Feeding conveyor belt 1 is used to feed and transport pipes of different diameters after they have been cut. Multiple temporary storage units 2 are installed on one side of the feeding conveyor belt 1 in the conveying direction; Multiple feeding units 3 are disposed between the multiple temporary storage units 2 and the feeding conveyor belt 1, and are used to feed materials from the pipes on the feeding conveyor belt 1 to the temporary storage units 2; The unloading conveyor belt 4 and the loading conveyor belt 1 are located on both sides of the temporary storage unit 2. When the unloading conveyor belt 4 is sent to the grinding process, it can be set into multiple branch conveyor belts. In this way, a grinding device can be set at each branch, which can improve the overall processing efficiency of a production line. Multiple feeding units 5 are disposed between the multiple temporary storage units 2 and the feeding conveyor belt 4, and are used to feed materials from the pipes on the multiple temporary storage units 2 onto the feeding conveyor belt 4.

[0018] The temporary storage unit 2 includes: Storage rack 21 is installed between the loading conveyor belt 1 and the unloading conveyor belt 4; Multiple placement rods 22 are evenly mounted on the storage rack 21 for arranging pipes from top to bottom according to their diameter from small to large. The placement rods 22 are arranged along the feeding conveyor belt 1 towards the unloading conveyor belt 4 and are inclined downwards towards the unloading conveyor belt 4. Multiple stop rods 23 are provided at the downward inclined end of each of the placement rods 22 to limit the pipe placed thereon.

[0019] Meanwhile, the feeding unit 3 includes: Multiple folding plates 31 are evenly arranged between the feeding conveyor belt 1 and the storage rack 21. The bending parts of the multiple folding plates 31 are connected by a connecting shaft 32. One end of the folding plate 31 extends to the lower end of the conveying roller of the feeding conveyor belt 1, and the other end extends to a position close to the placement rod 22. Two sets of bearing seats 33 are symmetrically arranged at both ends of the connecting shaft 32. One set of bearing seats 33 is equipped with a feeding motor 34. The rotating end of the feeding motor 34 is connected to one end of the connecting shaft 32 to drive the connecting shaft 32 to rotate. The other set of bearing seats 33 is equipped with a collar 35. The collar 35 is sleeved on the connecting shaft 32 to ensure stable rotation of the connecting shaft 32. The power component 36 is installed at the two sets of bearing seats 33 and is used to drive the bearing seats 33 to move up and down. The power component 36 is installed in the same way as the vertical moving component 55 described below, so as to realize the up and down movement of the bearing seats 33. The calibration component 37 is set on the two sets of bearing seats 33 and is used to calibrate the position of the pipe on the folding plate 31 after the pipe slides into the folding plate 31 when the feeding motor 34 drives the connecting shaft 32 to rotate, so that the pipe can be placed in an orderly manner after being fed to the storage rack 21. During the loading operation, when the pipe is transported to any of the storage racks 21 by the loading conveyor belt 1, the loading motor 34 drives the connecting shaft 32 to rotate, thereby causing the folding plate 31 to rotate. This causes the pipe to detach from the loading conveyor belt 1 and slide into the bend of the folding plate 31. Then, the power component 36 drives the bearing plate to move up and down, thereby moving the folding plate 31 to the position of the placement rod 22 of the storage rack 21 corresponding to the pipe diameter. Then, the loading motor 34 continues to drive the connecting shaft 32 to continue rotating, thereby causing the end of the folding plate 31 close to the placement rod 22 to rotate until it is parallel to the placement rod 22. This causes the pipe at the bend of the folding plate 31 to slide onto the corresponding placement rod 22. Then, the pipe slides on the placement rod 22 to the side of the downward loading conveyor belt 4 and is stopped by the stop rod 23 set at the end of the placement rod 22. The above operations are used to temporarily store pipes of different diameters. Meanwhile, when the pipe slides into the bend of the folding plate 31, it will be calibrated by the calibration piece 37. This way, after each pipe slides into the storage rack 21, the ends of each pipe will be aligned, making the storage more orderly and neat, and also facilitating the unloading unit 5 to unload the material. The multiple temporary storage units 2 allow for the placement of more pipes. During placement, pipes can be placed sequentially from the feeding direction to the back. Once a certain diameter pipe in a certain layer is full, the placement continues sequentially. This method can also be used during unloading, thus achieving a cycle. The temporary storage units 2 are designed for temporary placement of pipes after cutting, when the cutting speed is much faster than the grinding speed, enabling continuous pipe processing. Furthermore, since the temporary storage units 2 can be placed in an orderly manner for different pipe diameters, subsequent grinding operations can selectively grind the pipes according to actual needs, thereby enhancing the workability of the production line.

[0020] Additionally, the calibration component 37 includes: The first electric telescopic rod 371 is mounted on the bearing seat 33; Push plate 372, which is provided with the telescopic end of the first electric telescopic rod 371; When calibration is required, i.e. when the pipe slides into the bend of the folded plate 31, the first electric telescopic rods 371 at both ends will work synchronously, thereby synchronously driving the push plates 372 to move closer to each other, thus pushing the pipe towards the center of the folded plate 31 for symmetrical calibration. This step is because the feeding conveyor belt 1 does not stop transporting during actual operation, and there is a contact and disengagement process when the feeding unit 3 picks up the pipe. The pipe will continue to slide due to its motion inertia. This will cause an error each time the pipe is picked up by the folded plate 31. The calibration component 37 is used to solve this error, so that the position of each pipe will be uniform when it is fed to the temporary storage unit 2.

[0021] Meanwhile, the feeding unit 5 includes: A feeding strip 51 is disposed between the feeding conveyor belt 4 and the storage rack 21, and multiple sets of arc-shaped extraction plates 52 are evenly disposed on the feeding strip 51; The power unit is located at both ends of the feeding bar 51 and is used to drive the feeding bar 51 to move so as to pick up the pipe on the placement rod 22 and feed it onto the feeding conveyor belt 4.

[0022] The power assembly includes: Two sets of rotating shafts 53 are symmetrically and fixedly arranged on both sides of the feed strip 51; Two sets of strip-shaped sliding plates 54 are disposed at the rotating shaft 53, and the strip-shaped sliding plates 54 are provided with sliding grooves for the rotating shaft 53 to slide. Vertical moving parts 55 are disposed at both ends of the strip slide plate 54 and are used to drive the strip slide plate 54 to move up and down; The forward and backward movement adjustment component 56 is disposed between the strip slide plate 54 and the rotating shaft 53, and is used to drive the feeding strip plate 51 to move forward and backward, and to rotate when the feeding strip plate 51 is close to the feeding conveyor belt 4.

[0023] Additionally, the vertical moving member 55 includes: A vertical moving frame 551 is disposed at both ends of the strip slide plate 54, and the vertical moving frame 551 is provided with a limiting groove 552 for limiting the sliding of the strip slide plate 54; The threaded rod 553 is threadedly connected to the strip-shaped slide plate 54; A rotary motor 554 is mounted on the vertical moving frame 551 and is used to drive the threaded rod 553 to rotate. Finally, the forward and backward adjustment member 56 includes: A horizontal plate 561 is fixedly installed inside the strip slide plate 54 and has a hollowed-out design on the side near the feeding conveyor belt 4. In practice, the horizontal plate 561 is L-shaped, and the hollowed-out part is used for the rotation of the strip slide plate 54. The second electric telescopic rod 562 is fixedly installed on the horizontal plate 561, and the telescopic end of the second electric telescopic rod 562 is sleeved on the rotating shaft 53 through a collar 563. Gear 564 is coaxially mounted on the rotating shaft 53; A rack 565 is disposed on the horizontal plate 561 below the gear 564 and meshes with the gear 564; During the actual material feeding and unloading process, the vertical moving component 55 drives the strip slide 54 to move to the area below the pipe to be retrieved. Then, the forward and backward adjusting component 56 pulls the unloading strip 51 directly below the outermost pipe. The vertical moving component 55 then continues to move upward, pushing the pipe through the arc-shaped extraction plate 52 out of the placement rod 22 and above the stop rod 23. The forward and backward adjusting component 56 then moves the unloading strip 51 outward a certain distance, disengaging it from the vertical position of the placement rod 22. Next, the vertical moving component 55 drives the strip slide 54 slightly above the unloading conveyor belt. The conveyor belt 4 moves to a new position, and then the second electric telescopic rod 562 continues to push the unloading strip 51 to move to the unloading conveyor belt 4. At this time, the unloading strip 51 will move laterally on the horizontal plate 561. When it reaches the hollow part of the horizontal plate 561, the gear 564 will contact the toothed plate. As it continues to move, the strip slide 54 will rotate until it rotates to a certain angle. The pipe located on the arc-shaped extraction plate 52 will roll off onto the unloading conveyor belt 4. Then the strip slide 54 will reset, and the unloaded pipe will be transported by the unloading conveyor belt 4 to the grinding process for grinding.

[0024] Example 2 The difference between this embodiment and Embodiment 1 is that this embodiment also provides a production process for storing and calling the production line of an automated three-dimensional warehouse for pipelines, including the following steps: Step 1: Pipes of different diameters will be cut into sections by a cutting process, and then transported to temporary storage unit 2 by feeding conveyor belt 1. Step 2: The feeding unit 3 will place the pipes of different diameters transported by the feeding conveyor belt 1 in an orderly and neat manner on the storage rack 21 at the corresponding positions; Step 3: Based on the grinding requirements, the unloading unit 5 will remove the pipe from the storage rack 21 and onto the unloading conveyor belt 4 according to the pipe diameter required for grinding. Step 4: The unloading conveyor belt 4 will transport the pipes removed from the unloading unit 5 to different grinding processes for grinding operations through a diversion method.
