Description

Technical Field

[0001] This utility model relates to the field of gas cylinder filling technology, specifically a complete propane gas cylinder filling production line. Background Technology

[0002] Existing gas filling production lines mostly adopt a segmented manual operation mode. Traditional production lines usually disperse the processes of gas cylinder transportation, information collection, filling, testing, and cleaning, relying on manual transfer and manual docking, which leads to poor process connection and high operation error rate. In particular, propane is a flammable gas, and the safety requirements for the filling environment are very strict.

[0003] However, traditional production lines have low integration, and key processes such as oxygen concentration detection and combustible gas purity verification are prone to delays or misjudgments due to human intervention, which may create safety hazards. In addition, the weighing sensors in traditional production lines are scattered, resulting in more cylinder transfers, lower efficiency in verification and maintenance, and more manual operation.

[0004] Therefore, in order to solve the above problems, a complete propane cylinder filling production line is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a complete propane cylinder filling production line to improve the integration of the production line and thus solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The entire propane cylinder filling production line includes a first conveyor line and equipment rooms. The first conveyor line is arranged along the conveying direction with a waiting area, five equipment rooms and a qualified area. The waiting area and the three equipment rooms near the waiting area are connected by a second conveyor line and installed with the same unqualified area. The second and third equipment rooms near the waiting area are each equipped with a clamping mechanism. The five equipment rooms are arranged along the conveying direction of the first conveyor line with an information collection mechanism, a filling mechanism, a filling re-inspection mechanism, a cleaning mechanism and a labeling machine.

[0007] Specifically, the clamping mechanism includes a platform, a first rodless cylinder, a second rodless cylinder, and an arc-shaped plate. A pair of first rodless cylinders are vertically fixed in the equipment room. A platform is installed between the slides of the first rodless cylinders via a support frame. A pair of second rodless cylinders and a pair of linear guides are fixedly installed on the upper side of the platform. An arc-shaped plate is fixedly installed on the slide of one side of the second rodless cylinder and on the slide of the linear guide on the other side via the same support beam. A pair of rollers are rotatably installed on the inner circumference of the arc-shaped plate.

[0008] Furthermore, each of the support frames is connected to the platform via a balancing sensor.

[0009] Specifically, the information collection mechanism includes a first rotary arm and a camera. The first rotary arm is fixedly installed on the top of the first device room near the filling area, and the camera is fixedly installed on the swing arm of the first rotary arm.

[0010] Specifically, the filling mechanism includes a vacuum pump, a programmable valve, an oxygen concentration detector, a filling pipe, a combustible gas detector, and a first docking gun. One end of a first straight pipe is fixedly installed in the second equipment room near the filling area. The other end of the first straight pipe is connected to the first docking gun via a metal flexible hose. The oxygen concentration detector and the combustible gas detector are connected to the first straight pipe. The filling pipe is connected to the upper side of the first straight pipe via a programmable valve, and the vacuum pump is connected to the lower side of the first straight pipe via a programmable valve.

[0011] Specifically, the filling re-inspection mechanism includes a second docking gun, a combustible gas detection probe, and a combustible gas purity detector. One end of a second straight pipe and at least three combustible gas detection probes are fixedly installed in the fourth equipment room near the filling area. The other end of the second straight pipe is connected to the second docking gun via a metal flexible tube, and the combustible gas purity detector is installed on the second straight pipe.

[0012] Specifically, the cleaning mechanism includes a second rotating arm, a spray frame, a hot air blower, and a brush. The second rotating arm and the hot air blower are fixedly installed in the fifth equipment room near the filling area. The second rotating arm is located at the top of the equipment room, and the hot air blowers are evenly distributed on the side walls of the equipment room. The spray frame and the brush are fixedly installed on the swing arm of the second rotating arm, and the spray frame and the brush are symmetrically arranged.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Integrated design improves efficiency: The first conveyor line connects the filling area, equipment room and qualified area, integrating the entire process of information collection, filling, re-inspection, cleaning and labeling, reducing manual transfer and segmented operation, realizing precise coordination of processes and improving the smoothness of the production line connection.

[0014] Safety performance is significantly enhanced: Before filling, the gas is inspected by an oxygen concentration detector and a combustible gas detector, and the filling process is also monitored by a combustible gas detection probe and a combustible gas purity detector, reducing safety hazards.

[0015] Precise control and closed-loop management: The clamping mechanism, in conjunction with the weighing sensor, accurately collects the weight of the gas cylinder. The second conveyor line diverts non-conforming products to the non-conforming area. After manual inspection and maintenance, the products re-enter the process, forming a closed loop and improving the efficiency of inspection and maintenance. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example content: Please see Figures 1 to 6 A complete propane cylinder filling production line is provided, including a first conveyor line 2 and equipment rooms 12. The first conveyor line 2 is arranged along the conveying direction with a filling area 1, five equipment rooms 12 and a qualified area 8. The filling area 1 and the three equipment rooms 12 close to the filling area 1 are connected by a second conveyor line 10 and are equipped with the same unqualified area 11. The filling area 1, qualified area 8 and unqualified area 11 are used to store gas cylinders for easy transfer.

[0020] Equipment room 12 is a rectangular box with doors on all four sides. Gas cylinders can pass through equipment room 12 in the front-to-back direction via the first conveyor line 2. Workers can operate or check the working status of the equipment in equipment room 12 from the left or right side. Infrared transmitters and infrared receivers are fixedly installed in equipment room 12, qualified area 8, and unqualified area 11 to ensure that gas cylinders enter the work station.

[0021] The first conveyor line 2 and the second conveyor line 10 are existing conveying equipment consisting of a belt conveyor, a tensioning device (which adjusts the belt tension through a screw to ensure smooth operation without slippage), a redirection device (including a redirecting roller assembly to change the belt path), and side rails (used to support the gas cylinders on both sides). The first conveyor line 2 is used to sequentially transport gas cylinders through the waiting-to-fill area 1, five equipment rooms 12, and a qualified area 8. If any unqualified gas cylinders are found in the three equipment rooms 12 near the waiting-to-fill area 1 during the inspection process, they can be transferred to the unqualified area 11 via the second conveyor line 10 for storage. After manual verification and maintenance, they are then sent back to the waiting-to-fill area 1 via the second conveyor line 10.

[0022] Clamping mechanisms 9 are installed in the second and third equipment rooms 12 near the filling area 1. The clamping mechanisms 9 are used to clamp the gas cylinders. The five equipment rooms 12 are arranged in sequence along the conveying direction of the first conveyor line 2, including an information collection mechanism 3 (used to collect the steel stamp information on the gas cylinder), a filling mechanism 4 (used to check the air condition inside the gas cylinder), a filling re-inspection mechanism 5 (used to fill the gas cylinder with gas), a cleaning mechanism 6 (used to clean the outer surface of the gas cylinder), and a labeling machine 7 (used to affix labels to the surface of the gas cylinder).

[0023] Please see Figure 3 and Figure 4 The structure of clamping mechanism 9: The clamping mechanism 9 includes a platform 91, a first rodless cylinder 92, a second rodless cylinder 93, and an arc plate 94. A pair of first rodless cylinders 92 are vertically fixed in the equipment room 12. The platform 91 is installed between the slides of the first rodless cylinders 92 via a support frame. The platform 91 is horizontally set and has a through slot at its center for passing through the gas cylinder. A pair of second rodless cylinders 93 and a pair of linear guide rails 96 are fixedly installed on the upper side of the platform 91. The pair of second rodless cylinders 93 and the pair of linear guide rails 96 are arranged along the conveying direction of the first conveyor line 2. An arc plate 94 is fixedly installed on the slide of one side of the second rodless cylinder 93 and the slide of the other side of the linear guide rail 96 via the same support beam. A pair of rollers 95 are rotatably installed on the inner circumference of the arc plate 94. The rollers 95 are vertically set.

[0024] The first rodless cylinder 92 is used to lift the platform 91 and other components on the platform 91. When it is lifted, it does not affect the transport of the gas cylinder. When the gas cylinder is transported to the equipment room 12 via the first conveyor line 2, the first rodless cylinder 92 can lower the platform 91 and other components on the platform 91. The cooperation of the second rodless cylinder 93 and the linear guide rail 96 can form two opposing arc plates 94, which clamp the gas cylinder in the middle through the roller 95, thereby accurately determining the position of the gas cylinder. It can also lift the platform 91 and other components on the platform 91 again, and at this time, the gas cylinder will also be lifted. At the same time, since the roller 95 can rotate circumferentially, the operator can rotate the gas cylinder circumferentially to adjust the orientation of the gas cylinder's air inlet end.

[0025] Each support frame is connected to the platform 91 via a weighing sensor 97. The four weighing sensors 97 are arranged in a rectangle at the four corners of the lower surface of the platform 91. They can collect weight information and compare the weight difference before and after lifting the gas cylinder to determine the weight of the gas cylinder.

[0026] Please see Figure 2 The structure of information collection agency 3: Information collection mechanism 3 includes a first rotating arm 31 and a camera 32. The first rotating arm 31 is fixedly installed on the top of the first equipment room 12 near the filling area 1, and the camera 32 is fixedly installed on the swing arm of the first rotating arm 31; the first rotating arm 31 can rotate clockwise (towards... Figure 1 (Using the direction as a reference) Rotate the camera 32 degrees around to collect image information on the gas cylinder (gas cylinder registration number, gas cylinder production date, inspection date, allowable filling weight, etc.). After completion, reset it counterclockwise.

[0027] Please see Figure 3 The structure of filling mechanism 4: The filling mechanism 4 includes a vacuum pump 41, a programmable valve 42, an oxygen concentration detector 43, a filling pipe 44, a combustible gas detector 45, and a first docking gun 46. One end of a first straight pipe is fixedly installed in the second equipment room 12 near the filling area 1. The other end of the first straight pipe is connected to the first docking gun 46 via a metal flexible hose. The oxygen concentration detector 43 and the combustible gas detector 45 are connected to the first straight pipe. The filling pipe 44 is connected to the upper side of the first straight pipe via the programmable valve 42. The filling pipe 44 is connected to an external filling device. The vacuum pump 41 is connected to the lower side of the first straight pipe via the programmable valve 42.

[0028] After the clamping mechanism 9 lifts the gas cylinder, it is weighed for the first time by the weighing sensor 97. Then, the staff manually connects the first docking gun 46 to the gas cylinder. At this time, the oxygen concentration detector 43 and the combustible gas detector 45 on the first straight pipe are connected through the programmable valve 42 to detect the gas in the cylinder. If the oxygen or combustible gas concentration exceeds the standard, the vacuum pump 41 is connected through the programmable valve 42 to purge the gas inside the cylinder so that the gas concentration and the weight of the cylinder are reduced to below the qualified value. After the cylinder is qualified, the filling pipe 44 is connected through the programmable valve 42 to fill the cylinder.

[0029] If either the gas concentration or the cylinder weight fails to meet the acceptable value, the cylinder is considered unqualified. The clamping mechanism 9 lowers the cylinder and resets it, then transfers it to the unqualified area 11 via the second conveyor line 10 for storage, pending manual inspection.

[0030] Please see Figure 5 The structure of the filling and re-inspection mechanism 5: The filling re-inspection mechanism 5 includes a second docking gun 51, a combustible gas detection probe 52, and a combustible gas purity detector 53. One end of a second straight pipe and at least three combustible gas detection probes 52 are fixedly installed in the fourth equipment room 12 near the filling area 1. The other end of the second straight pipe is connected to the second docking gun 51 through a metal flexible tube, and the combustible gas purity detector 53 is installed on the second straight pipe.

[0031] After the clamping mechanism 9 lifts the gas cylinder, it is weighed a second time by the weighing sensor 97. After the second docking gun 51 docks with the gas cylinder, the combustible gas purity detector 53 can detect the purity of the combustible gas. If both the purity of the combustible gas and the weight of the filled gas cylinder meet the standards, it is a qualified gas cylinder. After being put down, it can continue to be transported to the next process.

[0032] If either the purity of the combustible gas or the weight of the filled cylinder fails to meet the acceptable value, the cylinder is considered unqualified. The clamping mechanism 9 lowers the cylinder and resets it, then transfers it to the unqualified area 11 via the second conveyor line 10 for storage, pending manual inspection.

[0033] Please see Figure 6 The structure of cleaning mechanism 6: The cleaning mechanism 6 includes a second rotating arm 61, a spray frame 62, a hot air blower 63, and a brush 64. The second rotating arm 61 and the hot air blower 63 are fixedly installed in the fifth equipment room 12 near the filling area 1, and the second rotating arm 61 is located at the top of the equipment room 12. The hot air blowers 63 are evenly distributed on the side walls of the equipment room 12. The spray frame 62 and the brush 64 are fixedly installed on the swing arm of the second rotating arm 61, and the spray frame 62 and the brush 64 are symmetrically arranged.

[0034] The spray frame 62 is a uniformly distributed frame consisting of a delivery pipe and spray nozzles, connected to an external water supply device (such as a water supply tank consisting of a pump and a water tank) via a metal hose; the hot air blower 63 is an existing component with a structure including a fan and heating wire.

[0035] The second rotating arm 61 can simultaneously rotate the spray frame 62 and the brush 64 to spray and clean the gas cylinders entering the equipment room 12. It first rotates clockwise once and then counterclockwise once to reset. Then the hot air blower 63 works, and the generated hot air blows on the surface of the gas cylinder to dry it.

[0036] In addition, the first docking gun 46 and the second docking gun 51 are existing components with structures such as hollow gun body, handle, rotary joint and internal thread docking sleeve. The hollow gun body can be moved by holding the handle, and the internal thread docking sleeve can be rotated on the hollow gun body through the rotary joint to dock with the external thread input end of the gas cylinder.

[0037] The first rotary arm 31 and the second rotary arm 61 are existing devices with servo motors and swing arms. The output shaft of the servo motor can drive the swing arms to rotate circumferentially.

[0038] The label machine 7 is an existing device mainly composed of a label storage device, a printing device, a conveying mechanism, a camera, etc. Its working principle is as follows: after the gas cylinder enters the equipment room 12, the camera performs image recognition to avoid the contents on the gas cylinder (gas cylinder registration number, gas cylinder production date, inspection date, allowable filling weight, etc.); the printing device prints variable content labels in real time according to the gas cylinder information; the conveying mechanism transports the label from the storage device to the affixing position, and the label is firmly affixed to the designated area on the bottle body by rolling.

[0039] Alternatively, other types of label machines, such as laser marking machines, can be used, as long as they can perform variable marking.

[0040] The above-mentioned electrical components are electrically connected to the control cabinet of the production line. The control cabinet has a built-in PLC main controller, which integrates a frequency conversion drive module, an I / O interface module, and a touch screen HMI. It communicates in real time with the weighing sensors 97, oxygen concentration detectors 43, combustible gas detectors 45, and other sensors and actuators (such as the first rodless cylinder 92, the second rodless cylinder 93, the vacuum pump 41, and the hot air blower 63) of each device through the fieldbus. This enables the adjustment of the conveyor speed, the control of the timing of equipment actions, the real-time acquisition of detection data, and logical judgment, ensuring the precise coordination of information collection, filling, testing, cleaning, labeling, and other processes.

[0041] Information about the filling process will also be archived and filling records will be generated for easy tracking and viewing.

[0042] The working principle of this embodiment: Gas cylinders start from the filling area 1 and enter the equipment room 12 sequentially via the first conveyor line 2.

[0043] The first equipment room 12 scans the gas cylinder stamp information through the information collection mechanism 3; The second equipment room 12 is where the gas cylinder is lifted by the clamping mechanism 9, the filling mechanism 4 detects the concentration of oxygen / combustible gas in the cylinder, and if it exceeds the standard, it is vacuumed. The weighing sensor 97 records the weight simultaneously. In the third equipment room 12, the gas cylinder is lifted again by the clamping mechanism 9, and the filling and inspection mechanism 5 connects to fill and test the gas purity, and weighs it a second time to confirm the filling amount. The fourth equipment room 12 uses the cleaning mechanism 6 to clean and dry the surface of the gas cylinders; The fifth equipment room 12 is labeled by label machine 7; Qualified gas cylinders are transported to qualified area 8, while unqualified gas cylinders are transferred to unqualified area 11 via the second conveyor line 10. After manual inspection and maintenance, they are returned to the waiting-to-fill area 1.
