Description

Technical Field

[0001] This invention relates to the field of stainless steel pipe stacking technology, specifically to a stacking device for an automated three-dimensional warehouse used in the production of stainless steel pipes. Background Technology

[0002] In the process of storing stainless steel pipes in an automated warehouse, the stainless steel pipes need to be stacked, bundled, and then clamped and moved into the warehouse to form a storage unit.

[0003] During the stacking process of stainless steel pipes, the stainless steel pipes need to be stacked layer by layer to form a bundle of stainless steel pipes of a specified shape. After the stacking is completed, the two ends of the stacked stainless steel pipes need to be aligned and adjusted uniformly. Due to the mutual compression and friction between the stacked stainless steel pipes, the alignment and adjustment is difficult.

[0004] Based on this, the present invention designs a palletizing device for an automated three-dimensional warehouse for stainless steel pipe production to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a palletizing device for an automated three-dimensional warehouse for stainless steel pipe production, in order to solve the problem mentioned in the background art that, in the process of stacking stainless steel pipes, it is necessary to stack the stainless steel pipes layer by layer to form a bundle of stainless steel pipes of a specified shape. After the stacking is completed, the two ends of the stacked stainless steel pipes need to be uniformly aligned and adjusted. Due to the mutual compression and friction between the stacked stainless steel pipes, the alignment and adjustment is difficult.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a palletizing device for an automated three-dimensional warehouse for stainless steel pipe production, comprising a transition rack and a stacking rack, and further comprising:

[0007] The lifting assembly includes two lifting plates, which are disposed at both ends of the transition material rack. The top of each lifting plate has multiple arc-shaped grooves, and multiple support wheels are rotatably disposed within the arc-shaped grooves. During the process of lifting the stainless steel tube on the transition material rack, the multiple arc-shaped grooves limit the movement of the stainless steel tube, and the support wheels provide rolling support for the stainless steel tube.

[0008] A clamping adjustment assembly is used to clamp the two ends of the multiple stainless steel tubes after the lifting plate lifts them, so that the ends of the multiple stainless steel tubes are flush.

[0009] A magnetic suction device is located above the transition rack and the stacking rack. It is used to magnetically suction the lifted and aligned stainless steel tube and transfer the magnetically suctioned stainless steel tube to the stacking rack.

[0010] As a further embodiment of the present invention, the lifting assembly further includes two pairs of cylinders, which are respectively fixedly installed on both sides of the transition material rack, and the piston rod ends of the two cylinders in the same pair are fixedly connected to the bottom of the lifting plate.

[0011] As a further embodiment of the present invention, a baffle assembly is provided at the end of the lifting plate. The baffle assembly includes two plug-in rods, which are fixedly connected to the side wall of the transition material rack. A baffle is slidably inserted into the surface of the two plug-in rods. A guide groove is provided on the side wall of the baffle. The guide groove includes a first vertical groove, a first inclined groove, and a second vertical groove. A guide pin is slidably disposed in the first vertical groove, and the guide pin is fixedly connected to the end of the lifting plate.

[0012] As a further embodiment of the present invention, the lifting plate includes a fixed base, which is fixedly connected to the piston rod ends of the same pair of two first cylinders. The end of the fixed base is fixedly connected to a guide pin. The top of the fixed base is provided with an installation groove, and a movable receiving plate is slidably inserted into the installation groove. A plurality of arc-shaped grooves are opened on the top of the movable receiving plate, and a first support spring is fixedly connected between the movable receiving plate and the inner wall of the installation groove.

[0013] As a further embodiment of the present invention, the clamping adjustment assembly includes two clamping seats located on both sides of the transition material rack. Two support columns are slidably inserted into the bottom end of the clamping seats. The two support columns are fixedly connected to the side wall of the transition material rack. A connecting plate is fixedly connected to the ends of the two support columns. Two second cylinders are fixedly connected to the surface of the connecting plate. The piston rod ends of the second cylinders are fixedly connected to the clamping seats.

[0014] As a further embodiment of the present invention, a connecting groove is provided at the top of the clamping seat, and two first support rollers are rotatably connected in the connecting groove. A clamping belt is drivenly connected to the surface of the two first support rollers, and a first support plate is provided in contact with the inner side of the clamping belt. The first support plate is fixedly connected to the inner wall of the connecting groove.

[0015] As a further embodiment of the present invention, two push plates are slidably connected to both sides of the transition material rack, and an electric cylinder is fixedly connected between the push plates and the surface of the transition material rack. A push slope is provided on the top of the push plates.

[0016] As a further embodiment of the present invention, a pressure sensor is fixedly installed on the inner bottom surface of the mounting groove, and a gas spring is provided in contact with the top of the pressure sensor. The gas spring is fixedly connected to the bottom of the movable receiving plate. A controller is fixedly installed on the side wall of the transition material rack. The controller controls the electric cylinder to adjust the height of the push plate based on the pressure value detected by the pressure sensor.

[0017] As a further embodiment of the present invention, the stacking rack includes a stacking seat, which is located behind the transition rack. A plurality of conveying rollers are rotatably connected to the top of the stacking seat, and two pairs of L-shaped support frames are fixedly installed on the top of the stacking seat. Each pair of support frames is rotatably connected to an inclined limiting roller, and the two limiting rollers in the same pair are symmetrically arranged.

[0018] As a further embodiment of the present invention, the magnetic attraction device includes two support rails, each with a slidably mounted hanger. A mounting base is fixedly connected to the bottom of each hanger. Two pairs of third cylinders are fixedly connected to the top of the mounting base, and the two pairs of third cylinders are fixedly connected to both ends of the top of the mounting base. A movable base is fixedly connected to the piston rods of the same pair of third cylinders after passing through the mounting base. Four connecting pins are slidably inserted into the bottom of the movable base. Electromagnetic blocks are fixedly connected to the bottom of the four connecting pins. Multiple clamping plates are fixedly connected to the bottom of the electromagnetic blocks. Second support springs are sleeved on the surfaces of the four connecting pins, and the two ends of the second support springs are fixedly connected to the movable base and the electromagnetic blocks, respectively.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. During the entire stacking process, the lifting component and the clamping adjustment component work together to align and clamp the two ends of the arranged stainless steel tubes. Before clamping, multiple stainless steel tubes are lifted, which limits the movement between them and keeps them in close contact. The surface of each stainless steel tube is also rolled to provide favorable conditions for clamping and adjustment. After aligning the ends of multiple stainless steel tubes, they are arranged in close contact with both ends aligned, which prepares them for subsequent magnetic transfer and stacking without the need to perform the end alignment operation after stacking.

[0021] 2. Due to the stacking of multi-layer stainless steel tubes, there is compression, resulting in high frictional resistance between the tubes. However, there is no compression between the single-layer stainless steel tubes at the transition rack. Therefore, aligning the ends of multiple single-layer stainless steel tubes at the transition rack reduces frictional resistance between the tubes and makes alignment easier compared to uniform alignment after stacking. This reduces the difficulty of alignment.

[0022] 3. Under the action of the arc groove, multiple stainless steel tubes are limited. After the stainless steel tubes enter the arc groove, the support wheels will provide rolling support to the surface of the stainless steel tubes, which realizes the movement of the stainless steel tubes away from the transition material rack and provides rolling support, providing the conditions for the alignment of the two ends of multiple stainless steel tubes in the later stage. During the process of lifting the plate, the lifting plate will drive the guide pin to move from the first vertical groove to the first inclined groove. During the movement of the guide pin in the first inclined groove, the guide pin will push the baffle, and the baffle will form a gap with the first blocked stainless steel tube, avoiding friction between the stainless steel tube and the surface of the baffle during the lifting process.

[0023] 4. By setting up a clamping strap, after the two clamping seats clamp and align the two ends of multiple stainless steel tubes, the clamping can be maintained at all times during the process of magnetically attracting and raising multiple stainless steel tubes. During the rise of the stainless steel tubes, the clamping strap can be moved until the stainless steel tubes are detached from the clamping strap. This achieves the goal of maintaining the alignment of the two ends of multiple stainless steel tubes at all times during the process of magnetically attracting and moving the stainless steel tubes away from the clamping seats.

Detailed Implementation

[0036] like Figures 1 to 10 As shown, in one embodiment, the palletizing device of the automated storage and retrieval system for stainless steel pipe production includes a transition rack 1 and a stacking rack, and further includes:

[0037] The lifting assembly includes two lifting plates 2, which are set at both ends of the transition material rack 1. The top of the lifting plate 2 is provided with multiple arc-shaped grooves 3, and multiple support wheels 4 are rotatably arranged in the arc-shaped grooves 3. During the process of lifting the stainless steel tube 39 on the transition material rack 1, the multiple arc-shaped grooves 3 limit the stainless steel tube 39, and the support wheels 4 provide rolling support for the stainless steel tube 39.

[0038] The clamping adjustment assembly is used to clamp the two ends of the multiple stainless steel tubes 39 after the lifting plate 2 lifts them, so that the ends of the multiple stainless steel tubes 39 are flush.

[0039] A magnetic suction device is located above the transition rack 1 and the stacking rack. It is used to magnetically suction the stainless steel tube 39 that has been lifted and clamped and aligned, and to transfer the magnetically suctioned stainless steel tube 39 to the stacking rack.

[0040] It should be understood that the palletizing process is as follows:

[0041] Arrange a specified number of stainless steel pipes 39: Place the stainless steel pipes 39 on the transition rack 1, and then arrange multiple stainless steel pipes 39 in a way that is appropriate. During the stacking process, stack five layers of stainless steel pipes. The number of pipes in the five layers from bottom to top is three, four, five, four, and three respectively. Therefore, the number of stainless steel pipes 39 arranged on top is three, four, five, four, and three respectively.

[0042] Lifting the stainless steel tube 39: The stainless steel tube 39 on the transition material rack 1 is lifted by the lifting plate 2 of the lifting assembly. During the process of lifting the stainless steel tube 39 on the transition material rack 1 by the lifting plate 2, multiple arc grooves 3 limit the stainless steel tube 39, and the support wheel 4 provides rolling support for the stainless steel tube 39.

[0043] Clamping adjustment: After the lifting plate 2 lifts multiple stainless steel tubes 39, the clamping adjustment assembly clamps both ends of the multiple stainless steel tubes 39, making the ends of the multiple stainless steel tubes 39 flush. During the clamping process of the two ends of the stainless steel tubes 39, the support wheel 4 provides rolling support to the surface of the stainless steel tubes 39. Under the limit of the arc groove 3, the multiple stainless steel tubes 39 are kept in close contact, preparing for subsequent transfer and stacking.

[0044] After stacking and aligning, the stainless steel tube 39: The magnetic suction device is located above the transition rack 1 and the stacking assembly. It is used to magnetically attract the lifted and aligned stainless steel tube 39, and transfer the magnetically attracted stainless steel tube 39 to the stacking rack. The stacking is completed by canceling the magnetic attraction. The five layers of stainless steel tube 39 are stacked in sequence.

[0045] Throughout the stacking process, the lifting and clamping adjustment components work together to align and clamp the two ends of the arranged stainless steel tubes 39. Before clamping, multiple stainless steel tubes 39 are lifted, which limits their movement and maintains their fit. Rolling support is also provided on the surface of each stainless steel tube 39 to facilitate clamping and adjustment. After aligning the ends of the multiple stainless steel tubes 39, they are arranged in a close fit with both ends aligned, preparing for subsequent magnetic transfer and stacking without the need for alignment after stacking.

[0046] The multi-layer stainless steel tubes 39 are squeezed due to stacking, resulting in high frictional resistance between them. However, there is no squeezing between the single-layer stainless steel tubes 39 at the transition rack 1. Therefore, aligning the ends of the multiple single-layer stainless steel tubes 39 at the transition rack 1 reduces the frictional resistance between them compared to uniformly aligning and adjusting the ends after stacking. This makes alignment easier and reduces the difficulty of alignment.

[0047] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the lifting assembly further includes two pairs of first cylinders 5, which are respectively fixedly installed on both sides of the transition material rack 1, and the piston rod ends of the same pair of first cylinders 5 are fixedly connected to the bottom of the lifting plate 2.

[0048] The end of the lifting plate 2 is provided with a baffle assembly, which includes two plug rods 6. The two plug rods 6 are fixedly connected to the side wall of the transition material rack 1. The surface of the two plug rods 6 is slidably inserted with a baffle 7. The side wall of the baffle 7 is provided with a guide groove 8. The guide groove 8 includes a first vertical groove 801, a first inclined groove 802 and a second vertical groove 803. A guide pin 9 is slidably disposed in the first vertical groove 801. The guide pin 9 is fixedly connected to the end of the lifting plate 2.

[0049] Specifically, conveying grooves 10 are provided at the top of both sides of the transition material rack 1. Two first transmission rollers 11 and two second transmission rollers 12 are rotatably arranged in the conveying grooves 10. The two first transmission rollers 11 are located above the two second transmission rollers 12. A conveyor belt 13 is connected between the two first transmission rollers 11 and the two second transmission rollers 12. A first motor 14 is fixedly installed on the side wall of the transition material rack 1. The output end of the first motor 14 is fixedly connected to the end of one of the first transmission rollers 11. A second support plate 42 is fixedly connected in the conveying groove 10. The top of the second support plate 42 is in contact with the inner side of the conveyor belt 13.

[0050] It should be understood that after the stainless steel pipe 39 is placed on top of the transition rack 1, the stainless steel pipe 39 will be placed on the conveyor belt 13. The stainless steel pipe 39 will be transported by the conveyor belt 13 and blocked by the baffle 7. Then the next stainless steel pipe 39 placed on the transition rack 1 will be transported by the conveyor belt 13 until the stainless steel pipes 39 come into contact with each other. Then the next stainless steel pipe 39 will be transported until a specified number is reached. The specified number of stainless steel pipes 39 will be blocked by the baffle 7 above the lifting plate 2 and directly above the multiple arc grooves 3. After the specified number of stainless steel pipes 39 are arranged, the transport will stop.

[0051] Then, the two pairs of first cylinders 5 are activated. The two first cylinders 5 push the lifting plate 2, and the two lifting plates 2 lift multiple stainless steel tubes 39. Under the action of the arc groove 3, the multiple stainless steel tubes 39 are limited. After the stainless steel tubes 39 enter the arc groove 3, the support wheel 4 will provide rolling support to the surface of the stainless steel tubes 39, which realizes that the stainless steel tubes 39 are moved away from the transition material rack 1 and are provided with rolling support, providing the conditions for the later alignment of the two ends of the multiple stainless steel tubes 39.

[0052] During the process of raising the lifting plate 2, the lifting plate 2 will drive the guide pin 9 to move from the first vertical groove 801 to the first inclined groove 802. During the movement of the guide pin 9 in the first inclined groove 802, the guide pin 9 will push the baffle 7. The baffle 7 will form a gap with the first blocked stainless steel tube 39 to avoid friction between the stainless steel tube 39 and the surface of the baffle 7 during the process of raising the plate 2.

[0053] like Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the lifting plate 2 includes a fixed base 201, which is fixedly connected to the piston rod ends of the two first cylinders 5. The end of the fixed base 201 is fixedly connected to the guide pin 9. The top of the fixed base 201 has an installation groove 202, in which a movable receiving plate 203 is slidably inserted. Multiple arc-shaped grooves 3 are formed on the top of the movable receiving plate 203. A first support spring 204 is fixedly connected between the movable receiving plate 203 and the inner wall of the installation groove 202. It should be understood that during the process of lifting the stainless steel tube 39, the movable receiving plate 203 first contacts the stainless steel tube 39. Then, as the first cylinder 5 continues to push, the fixed base 201 supports the movable receiving plate 203 through the first support spring 204, thereby achieving buffering and reducing rigid collision.

[0054] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the clamping adjustment assembly includes two clamping seats 15 located on both sides of the transition material rack 1. Two support columns 16 are slidably inserted into the bottom end of each clamping seat 15. The two support columns 16 are fixedly connected to the side wall of the transition material rack 1. Connecting plates 17 are fixedly connected to the ends of the two support columns 16. Two second cylinders 18 are fixedly connected to the surface of the connecting plates 17. The piston rod ends of the second cylinders 18 are fixedly connected to the clamping seats 15. It should be understood that after lifting multiple stainless steel tubes 39, the second cylinders 18 are activated, pushing the clamping seats 15. The two clamping seats 15 move relative to each other, clamping both ends of the lifted multiple stainless steel tubes 39 until the ends of the multiple stainless steel tubes 39 are aligned. During magnetic transfer, the clamping can be released by pulling with the second cylinders 18.

[0055] like Figure 4As shown, in one embodiment, a connecting groove 19 is provided at the top of the clamping seat 15. Two first support rollers 20 are rotatably connected within the connecting groove 19. A clamping belt 21 is drivenly connected to the surface of the two first support rollers 20. A first support plate 22 is disposed in contact with the inner side of the clamping belt 21 and is fixedly connected to the inner wall of the connecting groove 19. It should be understood that by setting the clamping belt 21, after the two clamping seats 15 clamp and align the two ends of the multiple stainless steel tubes 39, the clamping can be maintained at all times during the process of magnetically attracting the multiple stainless steel tubes 39 to rise. During the rise of the stainless steel tubes 39, the clamping belt 21 can be moved until the stainless steel tubes 39 are disengaged from the clamping belt 21. This achieves the goal of maintaining the alignment of the two ends of the multiple stainless steel tubes 39 at all times during the process of magnetically attracting and moving the stainless steel tubes 39 away from the clamping seat 15.

[0056] like Figure 2 , Figure 3 and Figure 9 As shown, in one embodiment, two push plates 23 are slidably connected to both sides of the transition rack 1. An electric cylinder 24 is fixedly connected between the push plate 23 and the surface of the transition rack 1. A push slope 2301 is provided on the top of the push plate 23. It should be understood that since the number of stainless steel tubes 39 between different layers will be adjusted, the number of stainless steel tubes 39 on the transition rack 1 will also be different. When the conveying stops, if the stainless steel tubes 39 on the side away from the baffle 7 deviates, it will affect the lifting plate 2 in lifting the stainless steel tubes 39. To avoid the above problem, after arranging multiple stainless steel tubes 39 on the transition rack 1, the electric cylinder 24 is activated. The electric cylinder 24 pushes the push plate 23 to rise. According to the number of stainless steel tubes 39, the push plate 23 is adjusted to different heights so that the push slope 2301 can push the stainless steel tubes 39 on the side away from the baffle 7 until the multiple stainless steel tubes 39 are fitted together, preparing for the subsequent lifting of multiple stainless steel tubes 39.

[0057] like Figure 7As shown, in one embodiment, a pressure sensor 25 is fixedly installed on the inner bottom surface of the mounting groove 202. A gas spring 26 is disposed in contact with the top of the pressure sensor 25. The gas spring 26 is fixedly connected to the bottom of the movable receiving plate 203. A controller 27 is fixedly installed on the side wall of the transition material rack 1. The controller 27 controls the electric cylinder 24 to adjust the height of the push plate 23 based on the pressure value detected by the pressure sensor 25. It should be understood that when different numbers of stainless steel tubes 39 are supported on the movable receiving plate 203, gravity will cause the movable receiving plate 203 to be squeezed. The movable receiving plate 203 will squeeze the pressure sensor 25 through the gas spring 26. The pressure value detected by the pressure sensor 25 increases with the increase of the number of stainless steel tubes 39. The controller 27 can make a one-to-one correspondence between the pressure detected by the pressure sensor 25 and the number of stainless steel tubes 39, and then control the electric cylinder 24 to move the push plate 23 to the height corresponding to the number of stainless steel tubes 39, so as to realize the automatic limiting arrangement of multiple stainless steel tubes 39.

[0058] like Figure 1 and Figure 2 As shown, in one embodiment, the stacking rack includes a stacking seat 40, which is located behind the transition rack 1. A plurality of conveying rollers 41 are rotatably connected to the top of the stacking seat 40. Two pairs of L-shaped support frames 28 are fixedly installed on the top of the stacking seat 40. Inclined limiting rollers 29 are rotatably connected to each pair of support frames 28, and the two limiting rollers 29 are symmetrically arranged. It should be understood that by setting the symmetrically arranged limiting rollers 29, the stainless steel tubes 39 stacked on the conveying rollers 41 are limited until the ends of the multi-layered stainless steel tubes 39 are stacked into a hexagonal shape.

[0059] like Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, in one embodiment, the magnetic attraction device includes two support rails 30, each with a slidably mounted hanger 31. A mounting base 32 is fixedly connected to the bottom of each hanger 31. Two pairs of third cylinders 33 are fixedly connected to the top of the mounting base 32. The two pairs of third cylinders 33 are fixedly connected to both ends of the top of the mounting base 32. The piston rods of the same pair of third cylinders 33 pass through the mounting base 32 and are fixedly connected to a movable base 34. Four connecting pins 35 are slidably inserted into the bottom of the movable base 34. Electromagnetic blocks 36 are fixedly connected to the bottom of the four connecting pins 35. Multiple clamping plates 37 are fixedly connected to the bottom of the electromagnetic blocks 36. Second support springs 38 are sleeved on the surfaces of the four connecting pins 35. The two ends of the second support springs 38 are fixedly connected to the movable base 34 and the electromagnetic blocks 36, respectively. It should be understood that the two support rails 30 are supported in the space, and the electromagnetic suction block 36 is moved by the movement of the hanger 31 on the support rails 30. After the multiple stainless steel tubes 39 on the transition rack 1 are lifted and aligned, the electromagnetic suction block 36 is moved to directly above the multiple stainless steel tubes 39. Then, the third cylinder 33 is activated, and the third cylinder 33 pushes the moving seat 34. The moving seat 34 drives the electromagnetic suction block 36 to lower its height until the stainless steel tubes 39 are limited by the clamping plate 37. An arc-shaped limiting cavity is formed between the clamping plates 37, and the electromagnetic suction block 36 magnetically attracts the stainless steel tubes 39. Then, the third cylinder 33 pulls the moving seat 34 until the stainless steel tubes 39 are away from the lifting plate 2. Then, the electromagnetic suction block 36 is moved to directly above the stacking rack. Then, the third cylinder 33 is activated again, and the third cylinder 33 pushes the moving seat 34 until the stacking is completed. Then, the power is turned off, the magnetic attraction of the electromagnetic suction block 36 is canceled, and the stacking is completed.
