Description

Technical Field

[0001] This application relates to the field of mechanical technology, and in particular to a multi-specification pipe fitting transport system. Background Technology

[0002] In shipbuilding, the loading of pipe fittings is a crucial step, referring to the process of moving pipe fittings from the raw material location to the automated warehouse. Traditional loading methods typically involve manual handling or flatbed truck transportation to move the pipe fittings from the raw material storage area to the automated warehouse.

[0003] However, the inventors discovered that this method was not only inefficient, but also limited in the range of pipe lengths that could be transported, and the pipes were not very stable during the placement process. Utility Model Content

[0004] This application provides a multi-specification pipe fitting transport and palletizing system to solve the problems of current palletizing methods being not only inefficient, but also having a narrow range of pipe fitting lengths that can be transported, and poor stability during the pipe fitting palletizing process.

[0005] This application provides a multi-specification pipe fitting transport and palletizing system, comprising: two or more transport machines, a synchronization mechanism, a drive mechanism, and at least one palletizing sensor;

[0006] Two or more of the conveyors are arranged in parallel to each other, and the two or more conveyors are used to output the pipe fittings from the loading position to the receiving platform; wherein, the loading position is located at one end of the conveyor and the receiving platform is located at the other end of the loading position;

[0007] The synchronization mechanism is connected to two or more of the transport aircraft respectively;

[0008] The drive mechanism is connected to the synchronization mechanism, and the drive mechanism enables two or more transport aircraft to operate synchronously through the synchronization mechanism.

[0009] The loading sensor is used to detect the pipe fittings in the loading platform;

[0010] If the loading sensor determines that the height of the pipes stacked in the loading platform has reached a height threshold, it sends a loading stop signal to the drive mechanism.

[0011] The infeed stop signal is used to instruct the drive mechanism to stop operating.

[0012] In the above scheme, the transport machine includes: a transport belt, a transport drive wheel, and a transport driven wheel;

[0013] The conveyor belt is fitted onto the driving wheel and the driven wheel;

[0014] The conveyor belt is used to transport the pipe fittings.

[0015] In the above scheme, the synchronization mechanism includes: two or more drive shafts, at least one drive coupling, two or more driven shafts, and at least one driven shaft coupling;

[0016] One of the drive shafts is connected to at least one of the transport drive wheels of the transport machine.

[0017] Two adjacent drive shafts are connected by one drive coupling;

[0018] One of the driven shafts is connected to at least one transport driven wheel of the transport machine;

[0019] The two adjacent driven shafts are connected by a driven coupling.

[0020] In the above scheme, the driving mechanism includes: a drive motor, a drive reducer, and a drive belt;

[0021] The drive motor is connected to the input end of the drive reducer;

[0022] The drive belt is fitted onto the output gear of the drive reducer and the drive gear on the drive shaft of the synchronization mechanism.

[0023] The above plan also includes: a framework;

[0024] At least one of the transport aircraft is located inside the frame;

[0025] The drive shafts at both ends of the synchronization mechanism are rotatably connected to both sides of the frame, respectively.

[0026] The driven shafts at both ends of the synchronization mechanism are rotatably connected to both sides of the frame.

[0027] The drive mechanism is fixed within the frame.

[0028] The above scheme also includes at least one blocking mechanism;

[0029] The blocking mechanism is fixed to the side of the frame facing the loading platform;

[0030] The blocking mechanism is connected to the loading sensor. If the blocking mechanism detects that the loading sensor generates a loading stop signal, the blocking mechanism will prevent the pipes on the transport machine from being output to the loading platform.

[0031] In the above scheme, the blocking mechanism includes: a blocking shaft, a mounting bracket, a blocking cylinder, and a magnetic switch;

[0032] The blocking shaft is connected to the blocking cylinder, the blocking cylinder controls the extension and retraction of the blocking shaft, the axial direction of the blocking shaft is parallel to the axial direction of the pipe fitting, and the blocking shaft is used to prevent the pipe fitting on the transport machine from being output to the loading platform.

[0034] If the magnetic switch detects that the loading sensor generates a loading stop signal, the magnetic switch sends an extension signal to the blocking cylinder. The extension signal is used to instruct the blocking cylinder to control the blocking shaft to extend, so that the blocking shaft prevents the pipe on the conveyor from being output to the loading platform.

[0035] If the magnetic switch does not detect the loading sensor generating a loading stop signal, the magnetic switch sends a retraction signal to the blocking cylinder. The retraction signal is used to instruct the blocking cylinder to control the retraction of the blocking shaft, so that the pipe on the transport machine can be output to the loading platform.

[0036] The above solution also includes: at least one feeding sensor;

[0037] The feeding sensor is used to detect the pipe fittings at the feeding position;

[0038] If the feeding sensor detects a pipe fitting at the feeding position, it sends a feeding stop signal to the drive mechanism; the feeding stop signal is used to instruct the drive mechanism to stop running.

[0039] The above scheme also includes: a moving mechanism and two moving tracks;

[0040] The moving mechanism is fixed to the frame;

[0044] In the above scheme, the moving mechanism includes: a moving motor, a moving reducer, and a moving belt;

[0045] The mobile motor is connected to the input shaft of the mobile reducer;

[0046] The moving belt is fitted onto the moving gear of the moving reducer and at least one moving gear on the moving shaft.

[0047] This application provides a multi-specification pipe fitting transportation and palletizing system. By setting up two or more conveyors and arranging them in parallel, it enables the transportation of pipe fittings of different lengths and specifications, and transports the pipe fittings from the loading position to the automated warehouse, thus expanding the applicable scope of pipe fitting transportation and palletizing.

[0048] By setting up a synchronization mechanism, the torque output by the drive mechanism can be synchronized to each conveyor, ensuring that each conveyor can transport the pipe fittings at the same speed and guaranteeing the stability of pipe fitting transportation.

[0049] By setting up loading sensors to detect pipes in the automated storage and retrieval system (AS / RS), if the height of the pipes stacked in the AS / RS reaches a height threshold, it indicates that the AS / RS is full. Therefore, a loading stop signal is sent to the drive mechanism to instruct the drive mechanism to stop running, thereby achieving the technical effect of automatically stopping the loading of pipes and improving the automation rate and reliability of pipe loading.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0095] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0096] The technical solutions of the embodiments of this application and how the technical solutions of the embodiments of this application solve the current problems are described in detail below with specific examples. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0097] Please see Figures 1-5 This application provides a multi-specification pipe fitting transport and palletizing system, including: two or more transport machines 1, a synchronization mechanism 2, a drive mechanism 3, and at least one palletizing sensor 4;

[0098] Two or more conveyors 1 are arranged in parallel to each other. The two or more conveyors 1 are used to output the pipe fittings 5 ​​from the loading position 11 to the automated storage and retrieval system 12. The loading position 11 is located at one end of the conveyor 1, and the automated storage and retrieval system 12 is located at the other end of the loading position 11.

[0099] Synchronization mechanism 2 is connected to two or more transport aircraft 1 respectively;

[0100] Drive mechanism 3 is connected to synchronization mechanism 2, and drive mechanism 3 enables two or more transport machines 1 to run synchronously through synchronization mechanism 2;

[0101] The loading sensor 4 is used to detect the pipe fittings 5 ​​in the automated storage and retrieval system 12;

[0102] If the loading sensor 4 determines that the height of the pipe fittings 5 ​​stacked in the automated storage and retrieval system 12 has reached the height threshold, it sends a loading stop signal to the drive mechanism 3.

[0103] The infeed stop signal is used to indicate that the drive mechanism 3 should stop operating.

[0104] In this example, by setting up two or more conveyors 1 and arranging them in parallel with each other, pipe fittings 5 ​​of different lengths and specifications can be transported, and the pipe fittings 5 ​​can be transported from the loading position 11 to the automated warehouse 12, thus expanding the applicable scope of transporting pipe fittings 5 ​​into pallets.

[0105] By setting a synchronization mechanism 2, the torque output by the drive mechanism 3 can be synchronized to each transport machine 1, ensuring that each transport machine 1 can transport the pipe fitting 5 at the same speed, thus guaranteeing the transportation stability of the pipe fitting 5.

[0106] By setting up a pallet sensor 4 to detect the pipe fittings 5 ​​in the automated storage and retrieval system 12, if the height of the pipe fittings 5 ​​stacked in the automated storage and retrieval system 12 reaches the height threshold, it indicates that the automated storage and retrieval system 12 is full. Therefore, a pallet stop signal is sent to the drive mechanism 3 to instruct the drive mechanism 3 to stop running, thereby achieving the technical effect of automatically stopping the pallet loading of pipe fittings 5 ​​and improving the automation rate and reliability of the pallet loading of pipe fittings 5.

[0107] In this embodiment, the pipe 5 is picked up by a robotic arm or a lifting device and placed at the loading position 11 to load the conveyor 1.

[0108] In a preferred embodiment, the transport machine 1 includes: a transport belt 13, a transport drive wheel 14, and a transport driven wheel 15;

[0109] The conveyor belt 13 is mounted on the driving wheel 14 and the driven wheel 15.

[0110] Conveyor belt 13 is used to transport pipe fitting 5.

[0111] In this example, by setting up a conveyor belt 13 to transport the pipe fitting 5, the noise of transporting the pipe fitting 5 is reduced, and the structure is simple, which reduces the failure rate of the conveyor 1.

[0112] Optionally, the conveyor belt 13 has at least one support groove 16 for accommodating the pipe fitting 5. By providing the support groove 16, the stability of the pipe fitting 5 on the conveyor belt 13 is ensured.

[0113] In a preferred embodiment, the synchronization mechanism 2 includes: two or more drive shafts 21, at least one drive coupling 22, two or more driven shafts 23, and at least one driven coupling 24;

[0114] One drive shaft 21 is connected to at least one transport drive wheel 14 of the transport machine 1, and two adjacent drive shafts 21 are connected by a drive coupling 22;

[0115] A driven shaft 23 is connected to at least one transport driven wheel 15 of a transport machine 1;

[0116] Two adjacent driven shafts 23 are connected by a driven coupling 24.

[0117] In this example, by setting up an active coupling 22, two active shafts 21 are connected, enabling multiple active shafts 21 to rotate synchronously. In this embodiment, the active coupling 22 has an overload protection function. If the torque transmitted on the active shaft 21 exceeds a certain threshold, the active coupling 22 can prevent this through its own destructive action, preventing the active shaft 21 from breaking due to bearing a large torque, thus protecting the active shaft 21 and the conveyor.

[0118] By setting a driven coupling 24 to connect two driven shafts 23, multiple driven shafts 23 can rotate synchronously. In this embodiment, the driven coupling 24 has an overload protection function. If the torque transmitted on the driven shaft 23 exceeds a certain threshold, the driven coupling 24 can prevent this through its own destructive action, preventing the driven shaft 23 from breaking due to the large torque, thus protecting the driven shaft 23 and the conveyor.

[0119] In a preferred embodiment, the drive mechanism 3 includes: a drive motor 31, a drive reducer 32, and a drive belt 33;

[0120] The drive motor 31 is connected to the input end of the drive reducer 32;

[0121] The drive belt 33 is fitted onto the drive gear 34 of the drive reducer 32 and the drive gear on the drive shaft 21 of the synchronization mechanism 2.

[0122] In this example, the drive motor 31 reduces the speed and increases the output torque through the drive reducer 32, and then drives the drive gear 34 through the drive belt 33 to rotate the drive gear, thereby causing the drive shaft 21 to rotate.

[0123] In a preferred embodiment, the multi-specification pipe fitting transport system further includes: a frame 6;

[0124] At least one transport aircraft 1 is located inside frame 6;

[0125] The drive shafts 21 at both ends of the synchronization mechanism 2 are rotatably connected to both sides of the frame 6;

[0126] The driven shafts 23 at both ends of the synchronizing mechanism 2 are rotatably connected to both sides of the frame 6;

[0127] The drive mechanism 3 is fixed inside the frame 6.

[0128] Specifically, the frame 6 includes: a frame body 61 and at least one partition beam 62;

[0129] At least one partition beam 62 is fixed in parallel inside the frame 61, dividing the inside of the frame 61 into two or more fixed spaces 63;

[0130] A transport machine 1 is located in a fixed space 63. A drive shaft 21 passes through at least one drive wheel of the transport machine 1 and at least one partition beam 62 in sequence. The drive shaft 21 is connected to at least one drive wheel and the drive shaft 21 is rotatably connected to at least one partition beam 62.

[0131] Two adjacent drive shafts 21 are connected by a drive coupling 22;

[0132] The two drive shafts 21 located at both ends of the synchronization mechanism 2 are rotatably connected to the two sides inside the frame 61, so that at least one drive wheel is rotatably connected to the frame 6.

[0133] A transport machine 1 is located in a fixed space 63, and a driven shaft 23 passes through at least one driven wheel of the transport machine 1 and at least one partition beam 62 in sequence. The driven shaft 23 is connected to at least one driven wheel and is rotatably connected to at least one partition beam 62.

[0134] Two adjacent driven shafts 23 are connected by a driven coupling 24;

[0135] The two driven shafts 23 located at both ends of the synchronization mechanism 2 are rotatably connected to the two sides inside the frame 61, so that at least one driven wheel is rotatably connected to the frame 6.

[0136] Furthermore, one end of the partition beam 62 is connected to one side beam of the frame 61, and the other end of the partition beam 62 has an output gap 64 between it and the other side beam of the frame 61. The pipe fittings 5 ​​on the conveyor 1 are output to the automated warehouse 12 through the output gap 64.

[0137] Optionally, the loading sensor 4 is fixed on the side of the frame 6 facing the automated storage and retrieval system 12.

[0138] A photoelectric sensor is used as the object-mounting sensor 4. The photoelectric sensor illuminates the object with light of a certain intensity from a light source, and then a receiver receives the light signals reflected, transmitted, scattered, or emitted from the object and converts them into electrical signals. This electrical signal is then processed by a signal processing circuit, including amplification, filtering, comparison, and counting, to ultimately achieve the detection and control of the object.

[0139] In a preferred embodiment, the multi-specification pipe fitting transport system further includes at least one blocking mechanism 7;

[0140] The blocking mechanism 7 is fixed to the side of the frame 6 facing the automated warehouse 12;

[0141] The blocking mechanism 7 is connected to the loading sensor 4. If the blocking mechanism 7 detects that the loading sensor 4 generates a loading stop signal, the blocking mechanism 7 will prevent the pipe fittings 5 ​​on the transport machine 1 from being output to the automated warehouse 12.

[0142] Optionally, the blocking mechanism 7 is fixed on the side of the frame 61 facing the automated storage and retrieval system 12.

[0143] In a preferred embodiment, the blocking mechanism 7 includes: a blocking shaft 71, a mounting bracket 72, a blocking cylinder 73, and a magnetic switch 74;

[0144] The blocking shaft 71 is connected to the blocking cylinder 73. The blocking cylinder 73 controls the extension and retraction of the blocking shaft 71. The axial direction of the blocking shaft 71 is parallel to the axial direction of the pipe fitting 5. The blocking shaft 71 is used to prevent the pipe fitting 5 on the conveyor 1 from being output to the automated warehouse 12.

[0145] Magnetic switch 74 is connected to blocking cylinder 73 and also to loading sensor 4. Magnetic switch 74 is used to detect whether loading sensor 4 generates a loading stop signal. If magnetic switch 74 detects that loading sensor 4 has generated a loading stop signal, magnetic switch 74 sends an extension signal to blocking cylinder 73. The extension signal is used to instruct blocking cylinder 73 to control blocking shaft 71 to extend, so that blocking shaft 71 prevents pipe fitting 5 on conveyor 1 from being output to automated storage and retrieval system 12. If magnetic switch 74 does not detect that loading sensor 4 has generated a loading stop signal, magnetic switch 74 sends a retraction signal to blocking cylinder 73. The retraction signal is used to instruct blocking cylinder 73 to control blocking shaft 71 to retract, so that pipe fitting 5 on conveyor 1 can be output to automated storage and retrieval system 12.

[0146] In this example, by setting a blocking shaft 71, the pipe fitting 5 is prevented from being output to or sliding out of the automated storage and retrieval system 12 when it is full, which would cause the pipe fitting 5 to fall off the automated storage and retrieval system 12 and damage the equipment and the pipe fitting 5.

[0147] Therefore, in this example, the blocking shaft 71 is set to block the pipe 5, and the blocking timing is when the magnetic switch 74 detects the loading stop signal, so as to ensure that the blocking shaft 71 blocks the pipe 5 and the drive mechanism 3 stops at the same time, and ensure that the pipe 5 can be reliably stopped on at least one transport mechanism 1.

[0148] In a preferred embodiment, the multi-specification pipe fitting transport system further includes: at least one loading sensor 8;

[0149] The feeding sensor 8 is used to detect the pipe fitting 5 on the feeding position 11;

[0150] If the feeding sensor 8 detects that there is a pipe fitting 5 on the feeding position 11, it sends a feeding stop signal to the drive mechanism 3; the feeding stop signal is used to instruct the drive mechanism 3 to stop running.

[0151] In this example, if the conveyor 1 is still running when it is being loaded, it will be impossible to place the pipe fitting 5 stably on the conveyor 1, causing the pipe fitting 5 to easily detach from the conveyor 1 and resulting in poor transport stability of the pipe fitting 5.

[0152] To address this, by installing a feeding sensor 8, the situation where the pipe fitting 5 cannot be stably placed on the conveyor 1 while it is still running is avoided, thus ensuring the transportation stability of the pipe fitting 5.

[0153] In a preferred embodiment, the multi-specification pipe fitting transport system further includes: a moving mechanism 9 and two moving tracks 10;

[0154] The moving mechanism 9 is fixed to the frame 6;

[0155] The bottom end of the frame 6 is movably connected to two moving tracks 10 via at least one moving wheel 91.

[0156] Two opposing moving wheels 91 on two moving tracks 10 are connected by a moving shaft;

[0157] The moving mechanism 9 is connected to at least one moving axis and is used to control the frame 6 to move on the moving track.

[0158] Optionally, the bottom end of the frame 6 is movably connected to a moving track 10 via at least one moving wheel 91.

[0159] In this example, the pipe fittings 5 ​​are placed into the three-dimensional warehouse 12 with multiple three-dimensional slots 121 by setting the moving mechanism 9. That is, the pipe fittings 5 ​​are placed into the multiple three-dimensional slots 121 in sequence, which ensures that the pipe fittings 5 ​​in the three-dimensional warehouse 12 can be more regular and orderly.

[0160] Specifically, the automated storage unit 12 has two or more automated slots 121, and the moving mechanism 9 is connected to the loading sensor 4. If the moving mechanism 9 detects the loading sensor 4, it generates a loading stop signal.

[0161] The moving mechanism 9 controls the frame 6 to move toward or away from the automated storage and retrieval system 12 by a preset interval distance, enabling the transport machine 1 to output the pipe fitting 5 to the next automated storage and retrieval system 121 in the automated storage and retrieval system 12. The interval distance is the straight-line distance between the axes of two adjacent automated storage and retrieval systems 121 in the automated storage and retrieval system 12.

[0162] In a preferred embodiment, the moving mechanism 9 includes: a moving motor 92, a moving reducer 93, and a moving belt;

[0163] The input shaft of the moving motor 92 is connected to the moving reducer 93;

[0164] The moving belt is fitted onto the moving gear 94 of the moving reducer 93 and the moving gear 94 on at least one moving shaft.

[0165] In this example, the moving motor 92 is used to provide power for the movement of the frame 6, and the moving gear 94 is coaxially connected to the moving shaft. By putting the moving belt on at least one moving gear 94 of the moving reducer 93, the moving gear 94 can drive at least one moving shaft to rotate, thereby achieving the technical effect of controlling the frame 6 to move on the moving track 10.

The multi-specification pipe fitting transport system according to claim 6, characterized in that, The blocking mechanism includes: a blocking shaft, a mounting bracket, a blocking cylinder, and a magnetic switch; The blocking shaft is connected to the blocking cylinder, the blocking cylinder controls the extension and retraction of the blocking shaft, the axial direction of the blocking shaft is parallel to the axial direction of the pipe fitting, and the blocking shaft is used to prevent the pipe fitting on the transport machine from being output to the loading platform. The magnetic switch is connected to the blocking cylinder and also to the tray insertion sensor. The magnetic switch is used to detect whether the tray insertion sensor generates a tray insertion stop signal. If the magnetic switch detects that the loading sensor generates a loading stop signal, the magnetic switch sends an extension signal to the blocking cylinder. The extension signal is used to instruct the blocking cylinder to control the blocking shaft to extend, so that the blocking shaft prevents the pipe on the conveyor from being output to the loading platform. If the magnetic switch does not detect the loading sensor generating a loading stop signal, the magnetic switch sends a retraction signal to the blocking cylinder. The retraction signal is used to instruct the blocking cylinder to control the retraction of the blocking shaft, so that the pipe on the transport machine can be output to the loading platform.
