Description

Technical Field

[0001] This application relates to the technical field of material palletizing equipment, and in particular to a palletizing device for uprights in the production of disc-lock scaffolding. Background Technology

[0002] Disc-lock scaffolding is a new type of construction scaffolding system. It mainly consists of uprights, horizontal bars, diagonal braces, adjustable bases, and adjustable top supports. Due to its unique structure and superior performance, disc-lock scaffolding has been widely used in construction. Among them, the uprights are the main load-bearing components of disc-lock scaffolding, and are usually made of steel pipes welded with discs and connecting sleeves.

[0003] Chinese patent application number CN202110821940.7, which relates to related technologies, proposes a galvanized disc-lock scaffolding upright stacking machine. It includes a feeding and distributing mechanism located between a feeding rack and a stacking mechanism. Disc-lock tubes are laid on the feeding rack, and multiple discs are spaced apart along the length of the disc-lock tubes. The feeding and distributing mechanism includes a feeding component and several guide blocks. The positions of the guide blocks correspond to the positions of the discs on the disc-lock tubes on the feeding rack. The guide blocks include a first guide surface and a second guide surface. The first guide surface and the second guide surface of the guide block work alternately to guide the discs passing through the guide blocks in two directions. The feeding component feeds the disc-lock tubes on the feeding rack into the stacking mechanism after they are guided by the guide blocks.

[0004] The aforementioned technologies have the following drawbacks: The discs on the uprights are typically welded onto the steel pipe at 50cm intervals. Therefore, precise positioning of the discs is necessary during upright production to ensure stability during scaffold assembly. Usually, during processing, the discs are first spot-welded onto the steel pipe for positioning before full welding; alternatively, full welding can be performed directly. Thus, positioning fixtures play a crucial role in the welding quality of the discs. However, in mass production, the positioning fixtures' accuracy decreases after prolonged use, worker errors, and impacts or improper stacking during transport after welding can all cause disc deformation, affecting the final quality of the scaffold uprights. Summary of the Invention

[0005] To address the issue of potential deformation of the discs on scaffolding uprights during processing and handling, which could lead to defective products in the finished product stacking and packaging, this application provides a disc-lock type scaffolding upright stacking device.

[0006] The technical solution of the disc-lock scaffolding production upright stacking device provided in this application is as follows:

[0007] A stacking device for uprights in the production of disc-lock scaffolding includes, in sequence:

[0008] The loading rack is used to store uprights;

[0009] Material racks are used to tightly and evenly lay out uprights;

[0010] A stacking mechanism is used to neatly stack the uprights laid flat on the material rack into the material frame in sequence;

[0011] A means is provided between the loading rack and the unloading rack:

[0012] The feeding mechanism is used to transfer the uprights on the feeding rack one by one to the discharge rack;

[0013] A rotating mechanism for driving one of the transferred uprights on the feeding mechanism to rotate at least one revolution;

[0014] The detection mechanism is used to detect the straightness of the disk of the rotating upright on the rotating mechanism;

[0015] A connection is provided between the feeding mechanism and the discharge rack:

[0016] The defective product discharge port is used to allow defective uprights to pass through;

[0017] A sealing plate is used to cover the defective product discharge port; and

[0018] The rejection mechanism is controlled and connected to the detection mechanism, and is configured to drive the sealing plate to move to expose the defective product discharge port when the detection mechanism detects a defect in the flatness of any disc on the upright.

[0019] Furthermore, the feeding mechanism includes:

[0020] The rotating shaft is orthogonal to the direction of the upright conveying;

[0021] Multiple material support trays are fixed to the outer peripheral wall of the rotating shaft and spaced apart along the axial direction of the rotating shaft.

[0022] Material support blocks are fixed to the outer peripheral wall of the arc surface of the material support plate and multiple blocks are arranged in a circular array at equal intervals around the axis of the material support plate. An arc groove for positioning the upright is provided between the material support blocks and the material support plate.

[0023] A stepper motor is used to drive the rotating shaft to rotate stepwise.

[0024] Furthermore, a sliding block adapted to the contour of the arc groove is fixedly connected to the groove wall.

[0025] Furthermore, the rotating mechanism includes:

[0026] A fixed frame is located at one end of the rotating shaft;

[0027] A movable frame is located at the other end of the rotating shaft and is slidably disposed between the loading frame and the unloading frame;

[0028] A first linear drive component is used to drive the movable frame to slide axially along the rotation axis;

[0029] An active disk is rotatably mounted on the side of the fixed frame near the movable frame, and the fixed frame is provided with a rotary drive component for driving the active disk to rotate.

[0030] The driven plate is rotatably mounted on the side of the movable frame near the fixed frame. The driven plate and the driving plate are coaxially arranged and their outer diameters are larger than the outer diameter of the upright.

[0031] When the stepper motor drives the rotating shaft to rotate step by step until the upright rod on it is aligned coaxially with the drive disk, it pauses for a set time and then drives the rotating shaft to rotate step by step again.

[0032] Furthermore, a pressure sensor is provided on the side of the active disk near the driven disk, and the pressure sensor is controlled to be connected to the rotary drive component;

[0033] When the pressure sensor detects that the pressure value of the pole end is reached, the rotary drive component is controlled to drive the active disk to rotate at least one revolution.

[0034] Furthermore, a friction layer is provided on the side of both the active disk and the driven disk that are close to each other.

[0035] Furthermore, an alignment plate is connected to the output end of the first linear drive unit, and a positioning plate is provided on the side of the active disk facing the rotation direction of the rotating shaft. The alignment plate and the positioning plate are correspondingly arranged. When the rotating shaft rotates to the point where one of its uprights is aligned with the active disk, the other upright is aligned with the positioning plate.

[0036] Furthermore, the positioning plate protrudes from the side of the driving disk near the driven disk, and the alignment plate is elastically mounted on the output end of the first linear drive member.

[0037] Furthermore, the testing institution includes:

[0038] A crossbar is provided along the length of the rotation axis;

[0039] The detection rods are hinged to the crossbar and are spaced apart. Each of the detection rods corresponds to a disk on the upright.

[0040] A bonding rod is fixed to the lower end of the detection rod and is used to bond with the side of the disk on the upright;

[0041] An angle sensor is mounted on the crossbar and is used to detect the flip angle of the detection bar;

[0042] A control component for controlling the bonding rod to move closer to or further away from the disc on the upright.

[0043] Furthermore, the control component includes:

[0044] The torsion elastic element has one end connected to the detection rod and the other end connected to the crossbar. When the fitting rod is attached to the side of the disc on the upright, the torsion elastic element is in a torsion state.

[0045] A control rod is provided along the length of the crossbar, and the end of the detection rod away from the fitting rod is movably hinged to the control rod;

[0046] The second linear drive is used to drive the controlled lever to move laterally along the length of the crossbar.

[0047] In summary, the beneficial technical effects of this application are as follows:

[0048] 1. During the process of the feeding mechanism transferring the uprights from the feeding rack to the discharge rack, when the uprights are transferred to the inspection station, the rotating mechanism drives the uprights to rotate at least one revolution. The inspection mechanism simultaneously performs straightness checks on multiple discs on the uprights. If the straightness of multiple discs on the uprights meets the standard, the feeding mechanism continues to transport the uprights to the sealing plate and slides them onto the discharge rack. When any disc is deformed or its perpendicularity to the steel pipe is not good, the rejection mechanism is controlled to drive the sealing plate to flip on the mounting frame to expose the defective product discharge port. The upright will fall from the defective product discharge port to automatically detect and reject defective products in the uprights before packaging, thus ensuring the quality of the uprights after packaging.

[0049] 2. An arc groove for positioning the upright is set between the material support block and the material support tray. The arc groove is set on the side of the material support block facing its rotation direction, and a resistant slider that matches its contour is fixed to the wall of the arc groove. The resistant slider can be made of high molecular plastic, such as PE, PTFE, etc., which can provide a smooth sliding and rotation environment for the upright and reduce damage to the paint layer on the upright.

[0050] 3. When the first linear drive unit drives the movable frame to approach the fixed frame to clamp the upright on the inspection station, the first linear drive unit also drives the alignment plate to push the upright on the inspection station towards the positioning plate, and finally presses the upright against the positioning plate, so that the upright on the inspection station is as close as possible to the surface of the fixed plate; thus, while clamping and fixing the upright on the inspection station, the upright on the inspection station can also be aligned end-to-end simultaneously, and the upright to be tested can be positioned and moved in two stages, thereby greatly reducing the damage to the paint surface caused by the upright after painting sliding a long distance in the arc grooves on multiple material support blocks, and also indirectly reducing the wear of the anti-slip slider on the arc groove, thus ensuring the accuracy of the inspection mechanism in detecting the flatness of the disc as much as possible.

[0066] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] This application discloses a pole stacking device for producing disc-lock scaffolding, referring to... Figure 1 and Figure 2 It includes the following, set in sequence:

[0068] The feeding rack 1 is used to store the uprights 8. It can be set at different heights at both ends so that the uprights 8 stored on it can automatically roll downstream under their own weight. Alternatively, a conveyor belt can be set on the feeding rack 1 so that the uprights 8 can be transported stably.

[0069] Material rack 2, used for tightly and flatly laying uprights 8;

[0070] The stacking mechanism is used to neatly stack the uprights 8 laid flat on the feeding rack 2 into the material box. Specifically, it can be a magnetic suction robot, and a lifting platform is set on the feeding rack 2 to lift a set number of uprights 8 to a certain height. Then the magnetic suction robot can transfer this part of the uprights 8 into the material box. It is the same as the conventional setting, and will not be described in detail here, nor is it shown in the figure.

[0071] A mounting frame 3 is provided between the feeding rack 1 and the discharging rack 2. The mounting frame 3 is equipped with:

[0072] The feeding mechanism is used to transfer the uprights 8 on the feeding rack 1 one by one to the discharge rack 2;

[0073] A rotating mechanism is used to drive one of the vertical rods 8 on the feeding mechanism to rotate at least one revolution;

[0074] The inspection mechanism is used to inspect the straightness of all the discs on the rotating upright 8 of the rotating mechanism.

[0075] A structure is provided between mounting bracket 3 and material discharge bracket 2:

[0076] Defective product discharge port 21 is used for the passage of defective uprights 8;

[0077] The sealing plate 22 covers the defective product discharge port 21. Specifically, the sealing plate 22 is inclined to receive and transition the upright 8 in the feeding mechanism of the mounting frame 3 to the discharge frame 2. The end of the sealing plate 22 closest to the mounting frame 3 is hinged to the mounting frame 3.

[0078] The rejection mechanism is controlled and connected to the detection mechanism, and is configured to drive the sealing plate 22 to the exposed defective product discharge port 21 when the detection mechanism detects a defect in the flatness of any disc on the upright 8. Specifically, the rejection mechanism is set as a cylinder, electric push rod, etc. The cylinder body of the rejection mechanism is hinged to the mounting frame 3 and the piston rod is hinged to the back of the sealing plate 22. The rejection mechanism is not shown in the figure.

[0079] Below the discharge rack 2, there is also a defective product rack 23 for collecting the defective product uprights 8 that fall from the defective product discharge port 21.

[0080] With this setup, after the uprights 8 on the feeding rack 1 are moved closer to the mounting frame 3, the feeding mechanism will sequentially transfer the uprights 8 on the feeding rack 1 to the discharge rack 2. During this process, the feeding mechanism will pause briefly during the movement of transferring one upright 8. During this period, the rotating mechanism will drive the upright 8 to rotate at least one revolution. The detection mechanism will simultaneously perform flatness detection on multiple discs on the upright 8. If the flatness of multiple discs on the upright 8 meets the standard, the feeding mechanism will continue to transport the upright 8 to the sealing plate 22, and with the help of the transition and guidance of the sealing plate 22, it will slide down to the discharge rack 2. When any disc deforms or is not perpendicular to the steel pipe, the rejection mechanism is controlled to cause the sealing plate 22 to flip on the mounting frame 3, so that the defective product drop port 21 is exposed. When the upright 8 is transferred by the feeding mechanism between the mounting frame 3 and the discharge frame 2, the sealing plate 22 cannot provide a transition or guiding function. Therefore, the upright 8 will fall from the defective product drop port 21 to automatically detect and reject defective products in the upright 8 before packaging, which can ensure the product quality of the upright 8 after packaging.

[0081] For specific settings, please refer to... Figure 2 and Figure 3 The aforementioned feeding mechanisms include:

[0082] The rotating shaft 31 is rotatably mounted on the mounting bracket 3 and is orthogonal to the conveying direction of the upright 8;

[0083] The material support tray 32 is fixed to the outer peripheral wall of the rotating shaft 31 and multiple trays are arranged at intervals along the axial direction of the rotating shaft 31.

[0084] The material support block 33 is fixed to the outer peripheral wall of the arc surface of the material support plate 32 and multiple blocks are arranged in a circumferential array at equal intervals around the axis of the material support plate 32. An arc groove 34 for positioning the upright 8 is provided between the material support block 33 and the material support plate 32. The arc groove 34 is located on the side of the material support block 33 facing its rotation direction. A resistant slider adapted to its contour is fixed to the wall of the arc groove 34. The resistant slider can be made of high molecular plastic, such as PE, PTFE, etc., which can provide a smooth sliding and rotation environment for the upright 8 and reduce damage to the paint layer on the upright 8.

[0085] Stepper motor 35 is mounted on mounting bracket 3 and is used to drive rotating shaft 31 to rotate step by step. Each rotation angle is the angle between the extension lines of two adjacent material support blocks 33 at the center of material support plate 32. When stepper motor 35 drives rotating shaft 31 to rotate, the arc groove 34 on material support block 33 can support the upright 8 on feeding rack 1 and transfer the upright 8 to discharge rack 2.

[0086] Therefore, when the stepper motor 35 drives the rotating shaft 31 to rotate, the multiple material support plates 32 on it rotate accordingly. When one of the material support blocks 33 on the material support plate 32 supports a vertical rod 8, the multiple material support blocks 33 on the same horizontal plane as the supporting block 33 jointly support the vertical rod 8. Then, as the material support plate 32 rotates step by step, it can lift the vertical rod 8 towards the material discharge rack 2. When the material support plate 32 rotates until the vertical rod 8 moves to the inspection station 91, the rotation mechanism drives the vertical rod... The pole 8 rotates in the arc grooves 34 on multiple material support blocks 33, which can ensure the stability of the pole 8 during rotation. At the same time, the detection mechanism detects the straightness of multiple discs on the pole 8. After the detection is completed, the stepper motor 35 drives the rotating shaft 31 to continue rotating, and the pole 8 on the detection station 91 is transferred to move towards the material rack 2. Another pole 8 upstream of the pole 8 is lifted to the detection station 91 for detection. This allows for the detection of each pole 8 individually to ensure the quality of the pole 8 before it leaves the factory.

[0087] If random inspection of the production quality of the upright pole 8 is to be carried out, the pause duration of the stepper motor 35 at a certain moment is controlled so that the upright pole 8, which is at the inspection station 91 at this moment, has enough time to be inspected by the rotating mechanism and the inspection mechanism, thereby realizing random inspection of the upright pole 8 to meet the requirements of rapid packaging.

[0088] On the other hand, refer to Figure 1 and Figure 3 The aforementioned rotating mechanism includes:

[0089] The fixing bracket 41 is fixedly connected to the mounting bracket 3 and located at one end of the rotating shaft 31;

[0090] The movable frame 42 is slidably mounted on the mounting frame 3 and located at the other end of the rotating shaft 31. The movable frame 42 is slidably mounted between the feeding frame 1 and the discharging frame 2.

[0091] The first linear drive member 43 is used to drive the movable frame 42 to slide axially along the rotation axis 31. Specifically, the first linear drive member 43 can be a cylinder, an electric push rod, a linear motor, etc., which can push the movable frame 42 closer to or away from the fixed frame 41. Moreover, to facilitate the application of the pole stacking device of this application to poles 8 of different sizes, in another feasible embodiment, an adjusting seat that can move along the length direction of the rotation axis 31 can be provided on the mounting frame 3. The first linear drive member 43 is fixed on the adjusting seat, and the movable frame 42 is slidably set on the adjusting seat or the mounting frame 3. This increases the adjustment range of the distance between the movable frame 42 and the fixed frame 41, and can accommodate poles 8 with larger spans.

[0092] The active disk 44 is rotatably mounted on the side of the fixed frame 41 near the movable frame 42, and the fixed frame 41 is provided with a rotary drive 46 for driving the active disk 44 to rotate. The rotary drive 46 can be a geared motor.

[0093] The driven plate 45 is rotatably mounted on the side of the movable frame 42 near the fixed frame 41. The rotation axis 31 of the driven plate 45 on the movable frame 42 is coaxial with the rotation axis 31 of the driving plate 44 on the fixed frame 41. The driven plate 45 and the driving plate 44 are coaxially arranged and their outer diameters are larger than the outer diameter of the upright 8. A friction layer 47 is provided on the side of the driving plate 44 and the driven plate 45 that are close to each other. The friction layer 47 is a rubber layer and anti-slip texture can be provided on the rubber layer to reduce the wear on the end of the upright 8 and improve the clamping effect on the upright 8, so as to ensure that the driving plate 44 can stably drive the upright 8 and the driven plate 45 to rotate synchronously when rotating.

[0094] When the stepper motor 35 drives the rotating shaft 31 to rotate step by step until the upright 8 on it is coaxially aligned with the active disk 44, specifically when the upright 8 enters the detection station 91, the stepper motor 35 pauses for a set time and then drives the rotating shaft 31 to rotate step by step. The set time refers to the total time taken for the rotating mechanism and the detection mechanism to work together to complete the detection and for the active disk 44 and the driven disk 45 to release the clamping of the upright 8.

[0095] A pressure sensor is provided on the side of the active disk 44 near the driven disk 45. The pressure sensor is controlled and connected to the rotary drive 46. Specifically, the pressure sensor is embedded in the friction layer 47 on the side near the active disk 44 or the driven disk 45, so that the pressure sensor can detect both the pressure of the upright 8 and the pressure of the driven disk 8. When the pressure sensor detects that the pressure value of the end of the upright 8 reaches the preset value, the first linear drive 43 stops pushing the movable frame 42 and holds it in that position. The rotary drive 46 is controlled to drive the active disk 44 to rotate at least one revolution and then stop.

[0096] Thus, when the stepper motor 35 drives the rotating shaft 31 to rotate until one of the uprights 8 enters the inspection station 91, the two ends of the upright 8 are aligned with the active disk 44 and the driven disk 45 respectively. Then, the first linear drive 43 drives the movable frame 42 to move toward the fixed frame 41, so that the driven disk 45 pushes the upright 8 and presses it against the active disk 44. At this time, the active disk 44 and the driven disk 45 can firmly clamp the upright 8 between them with the help of the friction layer 47. At this time, the pressure value detected by the pressure sensor reaches the preset value, the first linear drive 43 stops driving, the rotary drive 46 starts and drives the active disk 44 to rotate at least one revolution, so that the upright 8 and the driven disk 45 can rotate synchronously at least one revolution, so that the multiple disks on the upright 8 can rotate synchronously. During this period, the inspection mechanism synchronously detects the flatness of each disk, and can detect the quality defects of the disks in real time.

[0097] Additionally, refer to Figure 3 and Figure 4 To reduce the working time of the rotating mechanism and improve the detection efficiency, an alignment plate 51 is also connected to the output end of the first linear drive 43. A positioning plate 52 is provided on the side of the active disk 44 facing the rotation direction of the rotating shaft 31, and the alignment plate 51 and the positioning plate 52 are correspondingly arranged. When the rotating shaft 31 rotates to the point where one of its uprights 8 is aligned with the active disk 44, the other upright 8 near the loading rack 1 is aligned with the positioning plate 52. At this time, the other upright 8 is in the inspection position. The positioning plate 52 protrudes from the side of the active disk 44 near the driven disk 45. The alignment plate 51 is elastically mounted on the output end of the first linear drive 43. Specifically, a spring is provided between the alignment plate 51 and the output end of the first linear drive 43 so that when the alignment plate 51 moves toward the positioning plate 52, it can elastically press against the upright 8 in the inspection position; or an elastic layer, such as sponge or hollow rubber sleeve, is provided on the side of the alignment plate 51 near the positioning plate 52.

[0098] Thus, when the first linear drive 43 drives the movable frame 42 toward the fixed frame 41 to clamp the upright 8 on the inspection station 91, the first linear drive 43 also drives the alignment plate 51 to push the upright 8 on the inspection station toward the positioning plate 52, and finally presses the upright 8 against the positioning plate 52, so that the upright 8 on the inspection station is as close as possible to the surface of the fixed plate; thus, when clamping and fixing the upright 8 on the inspection station 91, the upright 8 on the inspection station can also be aligned end-to-end at the same time, and the upright 8 to be tested can be positioned and moved in two stages, thereby greatly reducing the damage to the paint surface caused by the upright 8 sliding a long distance in the arc groove 34 on the multiple material support blocks 33 after painting, and also indirectly reducing the wear of the anti-slip slider on the arc groove 34, so as to ensure the accuracy of the inspection mechanism in detecting the flatness of the disc as much as possible.

[0099] Specifically, refer to Figure 1 , Figure 3 and Figure 5 The testing institutions include:

[0100] The crossbar 61 is set along the length of the rotation axis 31;

[0101] The detection rods 62 are hinged to the crossbar 61 and are spaced apart. The multiple detection rods 62 correspond one-to-one with the multiple discs on the uprights 8. In order to adapt to uprights 8 of different sizes, a slide block 65 is slidably provided on the crossbar 61. A locking bolt 66 with one end pressed against the crossbar 61 is threaded through the slide block 65. The detection rods 62 are hinged to the slide block 65. The crossbar 61 has a non-circular cross section, such as rectangular, polygonal, or oval.

[0102] The bonding rod 63 is fixed to the lower end of the detection rod 62 and is used to bond with the side of the disk on the upright rod 8. The angle between the bonding rod 63 and the detection rod 62 is an acute angle, and the material of the bonding rod 63 is also a high-molecular plastic, such as PE, PTFE, etc., to reduce the wear on the paint layer on the disk.

[0103] An angle sensor 64 is mounted on the crossbar 61 and is used to detect the flipping angle of the detection rod 62. The flipping axis of the crossbar 61 on the slide 65 is orthogonal to the length direction of the crossbar 61.

[0104] A control component for controlling the contact rod 63 to move closer to or further away from the disc on the upright 8.

[0105] The control components include:

[0106] The torsion elastic element 71 is connected to the detection rod 62 at one end and to the crossbar 61 at the other end, specifically to the slide block 65 at the other end. When the contact rod 63 is in contact with the side of the disk on the upright rod 8, the torsion elastic element 71 is in a torsion state.

[0107] The control rod 72 is set along the length of the crossbar 61. The end of the detection rod 62 away from the fitting rod 63 is movably hinged to the control rod 72. Specifically, the upper end of the detection rod 62 is provided with a long groove 621 set along its length. Multiple sliders 721 corresponding to multiple detection rods 62 are fixedly connected to the control rod 72. The sliders 721 are prevented from sliding out and sliding in the long grooves 621 on the corresponding detection rods 62.

[0108] The second linear drive 73 is used to drive the control rod 72 to move laterally along the length of the crossbar 61. Specifically, it is used to drive the control rod 72 to move away from the disc on the upright 8 on the detection station 91. The output end of the second linear drive 73 is fixedly connected to a push plate 731 corresponding to the end of the control rod 72. Multiple positioning sleeves are fixedly connected to the mounting bracket 3, and the control rod 72 passes through the multiple positioning sleeves. By not directly connecting the push plate 731 to the control rod 72, the detection rod 62 can be easily rotated freely on the slide 65 during detection.

[0109] Thus, when the feeding mechanism is transferring the upright 8, the second linear drive 73 drives the crossbar 61 to move laterally. The crossbar 61 drives multiple detection rods 62 to flip on the corresponding slide block 65 through multiple sliders 721 on it, so that the contact rod 63 on the detection rod 62 is away from the movement trajectory of the disc on the upright 8 being transferred. At this time, the torsional elastic element 71 is torn and deformed. After the upright pole 8 is transferred to the inspection station 91, the rotating mechanism clamps the upright pole 8, and the second linear drive 73 drives its piston rod away from the crossbar 61. At this time, the detection rod 62 is pushed to flip by the torsional deformation force of the torsional elastic element 71 on it so that the contact rod 63 on it is in contact with the side of the disc on the upright pole 8. Then, while the active disc 44 and the driven disc 45 drive the upright pole 8 to rotate, the contact rod 63 detects the flatness of the disc. When the disc is deformed or the perpendicularity between the disc and the steel pipe is not up to standard, the rotating disc will push the contact rod 63, causing the detection rod 62 to flip in the opposite direction at a certain angle on the slide 65 and be detected by the angle sensor 64. Finally, when it is transferred to the intersection of the mounting frame 3 and the discharge frame 2, it is discharged from the defective product discharge port 21 by the rejection mechanism for production personnel to inspect. This can realize the automatic detection and rejection of defective products in the upright pole 8.

[0110] Furthermore, in other feasible embodiments, each angle sensor 64 can be connected to a signal light or an automatic marking device, so that when any angle sensor 64 detects an abnormality on the disc on the pole 8, the automatic marking device can directly mark the disc, making it convenient for maintenance personnel to quickly repair the defective disc; or the signal light can indicate the location of the abnormal disc, and after the pole 8 is discharged from the defective discharge port 21, the abnormal disc can be manually marked and then sent to the repair area for repair.

[0111] The implementation principle of the upright stacking device for producing disc-lock scaffolding in this application is as follows:

[0112] After the uprights 8 on the loading rack 1 are transferred to the vicinity of the mounting frame 3, the material support plate 32, when rotating, transfers the uprights 8 on the loading rack 1 to the unloading rack 2 through the arc groove 34 of the material support block 33 on it, via the test station 92 and the inspection station 91. During this process, when two adjacent uprights 8 are transferred to the test station 92 and the inspection station 91 respectively, the first linear drive member 43 drives the movable frame 42 and the alignment plate 51 to move towards the center of the mounting frame 3. The uprights 8 at the inspection station 91 are clamped and fixed between the active plate 44 and the driven plate 45, and the uprights 8 at the test station 92 are aligned between the positioning plate 52 and the alignment plate 51.

[0113] Subsequently, the second linear drive 73 drives the push plate 731 away from the control rod 72. Under the torsional deformation force of the torsion reset member, the detection rod 62 flips over and the bonding rod 63 on it is in close contact with the disc. Then, the active plate 44 drives the upright 8 that is pressed against it to rotate at least one revolution. The bonding rod 63, together with the angle sensor 64 on the detection rod 62, simultaneously performs flatness detection on multiple discs on the upright 8. If the flatness of multiple discs on the upright 8 meets the standard, the material tray 32 continues to transport the upright 8 to the sealing plate 22, and slides down to the discharge rack 2 with the help of the transition and guidance of the sealing plate 22. When any disc deforms or is not perpendicular to the steel pipe, the rejection mechanism is controlled to cause the sealing plate 22 to flip on the mounting frame 3, so that the defective product drop port 21 is exposed. When the abnormal upright 8 is transferred by the feeding mechanism between the mounting frame 3 and the discharge frame 2, the sealing plate 22 cannot provide a transition or guiding function. Therefore, the upright 8 will fall from the defective product drop port 21 to automatically detect and reject the defective products in the upright 8 before packaging, which can ensure the product quality of the upright 8 after packaging.
