Description

Technical Field

[0001] The present application relates to the technical field of liquid filling equipment, and in particular to a barrel receiving device for a filling equipment. Background Art

[0002] In the automotive manufacturing industry, filling liquid media (such as coolant and brake fluid) is a core process on the final assembly line. Because filling guns must cover a wide range of operating radiuses, their barrels typically reach 1.5-2.5 meters in length. Due to stringent production process regulations and the need for intensive production line space, the barrel must not be dragged on the ground during operation to avoid contamination of the media and reduce the risk of equipment entanglement.

[0003] Existing storage solutions mainly include four technical routes: fixed bracket, flexible suspension, magnetic and folding, all of which have significant defects: the fixed bracket has limited barrel angle adjustment due to its rigid structure; the flexible suspension device uses spring slides to improve flexibility, but the barrel swings greatly during use, threatening personnel safety; the magnetic solution relies on permanent magnet adsorption, and the magnetic force attenuates under high humidity conditions, resulting in frequent falling off; the folding structure achieves space compression through multiple hinges, but the multi-hinge structure is prone to failure.

[0004] There is an urgent need to develop a barrel storage solution that is resistant to environmental interference, has fast response, and is highly flexible. Summary of the Invention

[0005] In order to improve the flexibility of gun barrel storage, the present application provides a gun barrel storage device for a filling device.

The drive source of the retraction module drives the movable pulley to slide on the horizontal rails, cooperating with the pipe clamp in the restraint assembly to clamp the pipe section at one end of the gun barrel. The gun barrel is passed through each pipe clamp in sequence, secured to the storage rack by the pipe clamp, and then wound around the movable pulley. The sliding of the movable pulley can realize the retraction and extension of the gun barrel. This prevents the gun barrel from dragging on the ground, reduces the risk of contaminated media and equipment entanglement, and improves flexibility, reduces environmental interference, and reduces the probability of failure compared to existing storage solutions.

[0015] Optionally, a limiting bracket is further provided on the storage base, and the limiting bracket includes a top limiting frame and a side limiting frame connected to each other, the top limiting frame is fixed on the storage base, and the side limiting frame is fixed to one side of the guide wheel.

[0016] By adopting the above technical solution, the limiting bracket can limit the barrel at the guide wheel, improve the stability of the barrel during storage and release, prevent the barrel from deviating from the predetermined track or shaking significantly, and reduce the operation risk of the device.

[0017] Optionally, the side limiting frame includes a side limiting rod and connecting plates fixed at both ends of the side limiting rod, and the side limiting rod is outer-mounted with a limiting roller.

[0018] By adopting the above technical solution, the limiting roller is used to limit the gun barrel, preventing the gun barrel from swinging too much, thereby improving the safety of the equipment during use. At the same time, the setting of the limiting roller can effectively reduce the friction loss between the gun barrel and the limiting component, thereby extending the service life of the gun barrel.

[0019] Optionally, the pipe clamp includes a pipe seat and a clamping sleeve slidably arranged on the pipe seat, and the pipe seat is provided with a locking piece for locking the clamping sleeve.

[0020] By adopting the above technical solution, the pipe clamp adopts a structure of a pipe seat and a clamping sleeve slidably arranged on the pipe seat. The position of the clamping sleeve can be adjusted according to the size of the gun barrel to adapt to different gun barrels. At the same time, the locking piece arranged on the pipe seat can lock the clamping sleeve to ensure stable clamping of the gun barrel.

[0021] Optionally, the clamping sleeve includes a pressing plate and adjustment strips provided on both sides of the pressing plate, wherein the adjustment strips pass through the tube seat and are slidably connected to the tube seat;

[0022] The locking member includes a locking slide bar and a return spring provided on the tube seat, wherein the locking slide bar is slidably provided in the tube seat, and one end of the locking slide bar is gradually contracted toward the direction close to the adjustment strip;

[0023] Each of the adjusting strips is provided with a locking groove, and a plurality of the locking grooves are provided along the length direction of the adjusting strip. The reset spring is used to drive one end of the locking slide bar to slide into the locking groove.

[0024] By adopting the above technical solution, the adjustment strip is slidably connected to the tube seat, and the locking slide rod and the return spring cooperate to make one end of the locking slide rod slide into the locking groove at different positions on the adjustment strip, so that the clamping size of the tube clamp can be flexibly adjusted to adapt to gun barrels of different specifications, thereby enhancing the versatility of the tube clamp.

[0025] Optionally, a leak detection mechanism is further included, the leak detection mechanism including an air supply assembly, a temperature detector and a temperature control device; the air supply assembly includes an air inlet cylinder, an air delivery pipe and an air supply source, one end of the air delivery pipe is connected to the air inlet cylinder, and the other end of the air delivery pipe is connected to the gun barrel, and the air supply source is used to drive the gas in the air inlet cylinder to flow into the air delivery pipe;

[0026] The temperature detector is arranged on the storage base, and is used to detect the temperature around the barrel, and the temperature detector is electrically connected to the driving source;

[0027] The temperature control device is used to adjust the temperature of the gas in the air intake cylinder.

[0028] By adopting the above technical solution, the gun barrel is first leak-tested using a leak detection mechanism before introducing a liquid medium into the gun barrel. During the test, the air in the air intake is cooled or heated by a temperature control device. The heated air then enters the gun barrel along the air supply pipe under the action of the air supply source. During the test, the movable pulley is driven to slide, causing different sections of the gun barrel to slide to the temperature detector. The temperature detector then measures the temperature around each section of the gun barrel, thereby promptly detecting any leaks. If a leak occurs in a section of the gun barrel, the heated air directly escapes, and the temperature detector detects the sudden temperature change, thereby locating the leaking area on the gun barrel. The temperature detector is electrically connected to the drive source. When the temperature detector detects a temperature anomaly, the drive source is shut down, allowing the leaking area of ​​the gun barrel to remain at the temperature detector, making it easier for the operator to locate the leak.

[0029] Optionally, a hosting pulley is rotatably provided on the storage base frame, the hosting pulley is located on one side of the guide roller, and the temperature detector is located between the hosting pulley and the guide roller.

[0030] By adopting the above technical solution, the tube pulley can be used to assist in supporting the gun barrel, and at the same time, the temperature detector is set between the tube pulley and the guide roller, so that the temperature detector can detect the temperature around the pipe section moved between the tube pulley and the guide roller, so that the leakage on the gun barrel is not easily covered or blocked by other components, thereby improving the detection accuracy.

[0031] Optionally, a gas gathering sleeve is further fixed on the storage base, and the gas gathering sleeve is located between the hosting pulley and the guide roller. The temperature detector includes a temperature measuring end, and the temperature measuring end is located in the gas gathering sleeve.

[0033] Optionally, the temperature control device includes an electric heating tube and a temperature sensor, a plurality of the electric heating tubes are arranged in the air intake cylinder, and the temperature sensor is arranged at one end of the air supply pipe close to the air intake cylinder.

[0034] By adopting the above technical solution, the electric heating tube can be used to heat and increase the temperature of the gas in the air intake cylinder, and the temperature of the gas input from the air intake cylinder to the gas pipe can be accurately monitored by the temperature sensor to ensure that the temperature of the gas entering the gun barrel meets the requirements and reduce the impact of temperature changes on the gun barrel and the filling medium.

[0035] In summary, this application has at least one of the following beneficial effects:

[0036] 1. The present invention clamps a section of the barrel at one end with a pipe clamp and winds the barrel portion around a slidable movable pulley. The movable pulley slides, allowing the barrel to be flexibly retracted and extended, preventing the barrel from dragging on the ground and reducing the risk of medium contamination and equipment entanglement. 2. The movable pulley in the present invention slides on a horizontal slide rail to retract and extend the barrel. Compared with a fixed bracket, this solves the problem of limited barrel angle adjustment and provides greater flexibility.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-6 This application is described in further detail.

[0046] Example 1:

[0047] Reference Figure 1 and Figure 2 The barrel storage device for a filling device provided in an embodiment of the present application includes a storage rack 1, a storage module 2, and a constraint assembly 3. The storage rack 1 includes a storage base frame 11 and a horizontal slide rail 12. Multiple groups of storage base frames 11 are arranged at intervals along the same straight line, and adjacent storage base frames 11 are interconnected. A horizontal slide rail 12 is fixed to each storage rack 1. In this embodiment, four storage base frames 11 are specifically provided. The storage base frames 11 are generally made of metal materials, such as steel or aluminum alloy, and are capable of bearing the weight of the gun barrel 7 and related components. The horizontal slide rail 12 can be fixed to one side of the storage base frame 11 by bolts or welding, and its shape can be a T-shaped slide rail or a dovetail slide rail.

[0048] Reference Figure 1 , each storage base 11 is equipped with a retractable module 2, which includes a movable pulley 21, a driving source 22 and a limiting pulley 23. A slider is slidably connected to the horizontal guide rail, and the movable pulley 21 is mounted on the slider through a bearing, thereby realizing a sliding connection on the horizontal slide rail 12. The driving source 22 can be an electric push rod or a cylinder. In this embodiment, the driving source 22 is specifically configured as a pneumatic slide rail, and accordingly, the guide rail in the pneumatic slide rail is the horizontal slide rail 12. The cylinder in the pneumatic slide rail drives the slider to slide, thereby indirectly driving the movable pulley 21 to slide along the horizontal slide rail 12.

[0049] Reference Figure 1 The movable pulley 21 is fixedly connected to a mounting bracket 24, and the limiting pulley 23 is mounted on the mounting bracket 24 via a bearing, so that the limiting pulley 23 is rotatably connected above the movable pulley 21, and the rotation axis of the limiting pulley 23 is parallel to the rotation axis of the movable pulley 21. When in use, the pipe section of the gun barrel 7 needs to be passed between the limiting pulley 23 and the movable pulley 21. The setting of the limiting pulley 23 can prevent the pipe section of the gun barrel 7 from slipping out when sliding on the movable pulley 21, playing a limiting role, and making the retraction and extension of the gun barrel 7 more stable.

[0050] Reference Figure 3 The restraint assembly 3 includes a pipe clamp and a guide roller 35. The pipe clamp can be made of plastic or metal and is secured to the storage frame 11 by bolts or welding. In this embodiment, the pipe clamp is specifically configured as an annular jacket 31; two annular jackets 31 are fixed at intervals to the top of the storage frame 1, and one annular jacket 31 is fixed to the bottom of the storage frame 1. When the tube section of the gun barrel 7 is inserted into the annular jacket 31, a certain amount of friction is generated between the annular jacket 31 and the tube section of the gun barrel 7, thereby securing the tube section of the gun barrel 7 to the storage frame 11 and ensuring the stability of one end of the gun barrel 7. The annular jacket 31 has a certain degree of elasticity. In other embodiments, an axial opening can be cut into the outer wall of the annular jacket 31 to facilitate clamping and removal of the gun barrel 7.

[0051] The guide wheel 35 is positioned at one end of the storage base frame 11. A connecting shaft is coaxially fixed to the guide wheel 35, and one end of the connecting shaft is welded and fixed on the storage base frame 11. The guide wheel 35 can guide the direction of the gun barrel 7, making the gun barrel 7 smoother in the storage and release process.

[0052] Reference Figure 2 The storage base 11 is also provided with a limit bracket 36. The limit bracket 36 includes a top limit bracket 361 and a side limit bracket 362, which are connected to each other. The top limit bracket 361 is fixed to the storage base 11 at one end away from the side limit bracket 362, and the side limit bracket 362 is fixed to one side of the guide roller 35. The side limit bracket 362 includes a side limit rod 3621 and connecting plates 3622 fixed to both ends of the side limit rod 3621. One connecting plate 3622 is fixed to one end of the top limit bracket 361, and the other connecting plate 3622 is fixed to one side of the guide roller 35. The side limit rod 3621 is outer-mounted with a limit roller 3623. The side limit rod 3621 is specifically round and rod-shaped, allowing the limit roller 3623 to rotate on the side limit rod 3621. A plurality of limiting rollers 3623 are sleeved along the length direction of the side limiting rod 3621 , and the limiting rollers 3623 can be made of rubber.

[0053] During use, the gun barrel 7 is passed through the annular channel formed between the limiting bracket 36, the storage base 11, and the guide roller 35, and is then wound around the guide roller 35. The setting of the limiting bracket 36 further limits the position of the gun barrel 7. The top limiting bracket 361 prevents the gun barrel 7 from deviating upward, and the side limiting bracket 362 prevents the gun barrel 7 from deviating sideways. The setting of the limiting roller 3623 reduces friction with the gun barrel 7, making the gun barrel 7 smoother during storage and release, improving the restraint ability of the gun barrel 7, and further enhancing the stability and reliability of the gun barrel 7 on the storage frame 1.

[0054] In other embodiments, the side limiting rod 3621 may not be provided with the limiting roller 3623 .

[0055] The operating principle of this embodiment is as follows: During use, one end of the barrel 7 is first passed through each annular jacket 31 in sequence. Once secured, the barrel 7 can then be passed between the movable pulley 21 and the limiting pulley 23, and then along the annular channel formed between the limiting bracket 36, the storage base 11, and the guide roller 35. To store the barrel 7, the drive source 22 drives the movable pulley 21 away from the guide roller 35; to release the barrel 7, the drive source 22 drives the movable pulley 21 toward the guide roller 35. Compared to existing solutions, this solution is not restricted by a rigid structure, allowing for flexible adjustment of the barrel 7 position without the significant swinging of the barrel 7 that occurs with flexible suspension devices. It also avoids the humidity issues of magnetic suspension solutions and the malfunction-prone nature of foldable structures. It offers the advantages of environmental resistance, fast response, and high flexibility, effectively addressing the shortcomings of existing barrel 7 storage solutions and improving production efficiency and safety.

[0056] Example 2

[0057] The difference between this embodiment and the above embodiment is that:

[0058] Reference Figure 3 In this embodiment, the pipe clamp is configured as a pipe base 32 and a clamping sleeve 33. The pipe base 32 is fixed to the storage base 11 (not shown) by bolts or welding. The clamping sleeve 33 is formed from a bent metal plate and includes a pressure plate 331 and adjustment strips 332 integrally formed at each end of the pressure plate 331. The pressure plate 331 is curved to better conform to the surface of the gun barrel 7. The adjustment strips 332 can be rectangular. The pipe base 32 has through-holes 321 corresponding to the adjustment strips 332. Two adjustment strips 332 in the clamping sleeve 33 pass through corresponding through-holes 321 in the pipe base 32, achieving a sliding connection between the clamping sleeve 33 and the pipe base 32. Each adjustment strip 332 has a locking slot 3321, with multiple locking slots 3321 spaced along the length of the adjustment strip 332.

[0059] Reference Figure 3 Each through-hole 321 is connected to a locking member 34 on its inner sidewall. The locking member 34 comprises a locking slide 341 and a return spring 342. An adjustment slot 3211 is defined in the through-hole 321. One end of the locking slide 341 slides within the adjustment slot 3211, while the other end tapers into a conical shape. The return spring 342 fits over the locking slide 341, with one end fixedly connected to the locking slide 341 and the other end fixedly connected to the bottom of the adjustment slot 3211. When the adjustment bar 332 slides within the through-hole 321, aligning one locking slot 3321 with the locking slide 341, the return spring 342 allows the tapered end of the locking slide 341 to slide into the locking slot 3321, locking the clamping sleeve 33. To adjust the position of the clamping sleeve 33, the clamping sleeve 33 is simply slid so that one end of the locking slide 341 is inserted into a different locking slot 3321. This structure enables the pipe clamp to adapt to gun barrels 7 (not shown in the figure) of different diameters and to clamp firmly.

[0060] Example 3

[0061] The difference between this embodiment and embodiment 1 is that:

[0062] Reference Figure 4 and Figure 5 , a leak detection mechanism 4 is also provided. The leak detection mechanism 4 includes an air supply assembly 41, a temperature detector 42 and a temperature control device 43. The air supply assembly 41 includes an air inlet cylinder 411, an air supply pipe 413 and an air supply source 414. The air inlet cylinder 411 is specifically configured as a cylinder with one end closed, and the non-closed section of the air inlet cylinder 411 is covered and fixed with a filter 412. One end of the air supply pipe 413 is connected to the closed section of the air inlet cylinder 411, and the other end of the air supply pipe 413 is integrally formed with multiple air supply branches 4131; the air supply branches 4131 correspond one-to-one to the storage base 11, and are connected to the end of the gun barrel 7 on the storage base. Each air supply branch pipe 4131 is installed with an on-off valve 6 to control the on-off between the air supply branch pipe 4131 and the corresponding gun barrel 7.

[0063] In this embodiment, the air inlet cylinder 411 is made of metal, and the air delivery pipe 413 is made of a rubber tube. The air delivery source 414 is specifically an air pump, and the air delivery source 414 is connected to the pipe section of the air delivery pipe 413 near one end of the air inlet cylinder 411. When performing a leak test, the air delivery source 414 is activated to introduce external air into the air inlet cylinder 411, and then transported to the gun barrel 7 through the air delivery pipe 413 and the air delivery branch pipe 4131. Figure 5The temperature control device 43 is used to adjust the temperature of the gas in the air intake cylinder 411. The temperature control device 43 includes an electric heating tube 431 and a temperature sensor 432. The electric heating tube 431 is fixed to the inner wall of the air intake cylinder 411, and multiple electric heating tubes 431 are spaced around the axis of the air intake cylinder 411. The temperature sensor 432 is installed on the air supply pipe 413, located at the end of the air supply pipe 413 near the air intake cylinder 411. The temperature sensor 432 detects the temperature of the air discharged from the air intake cylinder 411. The power of the electric heating tube 431 is designed and adjusted according to the temperature detected by the temperature sensor 432 to ensure that the temperature of the gas entering the gun barrel 7 meets the requirements.

[0064] In other embodiments, the electric heating tube in the temperature control device 43 can also be replaced by a refrigerator or a heat exchanger.

[0065] Reference Figure 4 and Figure 6 The storage base 11 is also provided with a control pulley 13. A support is fixed to the storage base 11, and the support is located on one side of the guide roller 35. The control pulley 13 is rotatably connected to the support via a rotating shaft, thereby achieving a rotational connection between the control pulley 13 and the guide roller 35. Two connecting rods are fixed to the storage base 11. A temperature detector 42 is fixed to the storage base 11 via one connecting rod, and the temperature detector 42 is located between the control pulley 13 and the guide roller 35. The temperature detector 42 is electrically connected to the drive source 22. A gas collection sleeve 5 is detachably connected to the other connecting rod of the storage base 11 via bolts. The gas collection sleeve 5 is located between the control pulley 13 and the guide roller 35. During use, the gun barrel 7 needs to be wound around one end of the guide roller 35, passed through the gas collection sleeve 5, and then wound onto the control pulley 13.

[0066] In this embodiment, the temperature detector 42 is specifically an infrared thermometer. The temperature detector 42 includes a temperature measuring end, which is disposed within the gas collection sleeve 5 and specifically measures the temperature around the section of the gun barrel 7 located within the gas collection sleeve 5. The gas collection sleeve 5 can be cylindrical or semi-cylindrical. It can collect gas around the gun barrel 7, allowing the temperature measuring end of the temperature detector 42 to more accurately detect changes in gas temperature, thereby improving the sensitivity and accuracy of the leak detection mechanism 4 and ensuring effective monitoring of leaks in the gun barrel 7. In this embodiment, the gas collection sleeve 5 is specifically cylindrical.

[0067] If there is a leak in the barrel 7, air will directly overflow along the leaking area of ​​the barrel 7. The temperature detector 42 will detect the sudden temperature change, thereby determining the leaking area on the barrel 7. The temperature detector 42 is electrically connected to the drive source 22. When the temperature detector 42 detects a temperature anomaly, the drive source 22 is shut down, allowing the leaking area of ​​the barrel 7 to be located at the temperature detector 42, making it easier for operators to locate the leaking area and facilitate subsequent repairs.

[0068] In other embodiments, the gas gathering sleeve 5 may not be provided.

[0069] The working principle of this embodiment is as follows: before introducing the liquid medium into the gun barrel 7, the gun barrel 7 is first leak-tested by the leak detection mechanism 4. The electric heating tube 431 in the temperature control device 43 is activated to heat the gas in the air inlet 411. The temperature sensor 432 monitors the gas temperature in real time. When the gas temperature in the gun barrel 7 is suitable and constant, the gas supply source 414 is activated to transport the heated gas into the gun barrel 7 using the gas supply assembly 41. The driving source 22 drives the movable pulley 21 to move, causing different sections of the gun barrel 7 to move into the gas collection sleeve 5. The temperature detector 42 detects the temperature of the gun barrel 7 sections around the gas collection sleeve 5. If there is a leak in the gun barrel 7, the gas leakage will cause the ambient temperature to change significantly. The temperature detector 42 transmits an abnormal temperature signal to the driving source 22, which controls the movable pulley 21 to stop sliding, making it easy to promptly detect gun barrel 7 leaks and more convenient to detect minor leaks.

[0070] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
