Description
Technical Field
[0001] The invention relates to the technical field of liquid filling on a conveyor plate chain of an automobile, and in particular to a universal gun barrel anti-pull structure. Background Art
[0002] Traditionally, liquid filling on automobile conveyor chains is usually carried out by an online accompanying filling machine that moves synchronously with the automobile conveyor chain. After the filling gun placed on the online accompanying filling machine is inserted into the vehicle's filling port, the online accompanying filling machine will move with the vehicle on the conveyor chain. At this time, it is necessary to ensure that the filling gun on the online accompanying filling machine keeps running synchronously with the vehicle. If the online accompanying filling machine and the automobile conveyor chain are offset during movement, the synchronization between the filling gun and the vehicle's filling port will deviate. When the deviation is large, it is easy to damage the vehicle's filling port or cause damage to the filling gun and the filling gun barrel.
[0003] Regarding the above-mentioned related technologies, there are still some shortcomings. When a deviation occurs between the filling gun and the vehicle filling port, when the deviation is large, the vehicle filling port is easily damaged, or the filling gun and the filling gun barrel are damaged. Summary of the Invention
[0004] The purpose of this application is to provide a universal gun barrel anti-pull structure to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a universal gun barrel anti-pull structure, comprising a hanging frame, a gun barrel mounting mechanism, a movable buffer assembly and a detection assembly, wherein the hanging frame can move synchronously with the automobile conveyor plate chain; a sliding seat is slidably connected to the bottom of the hanging frame, the gun barrel mounting mechanism is fixed to the bottom of the sliding seat, the gun barrel mounting mechanism is used to hang multiple gun barrels, and the extension direction of the gun barrel is perpendicular to the sliding direction of the sliding seat; the movable buffer assembly is arranged between the sliding seat and the hanging frame, and the movable buffer assembly is used to limit the position of the sliding seat on the hanging frame so that the sliding seat is in a preset position under normal circumstances; the detection assembly is arranged on the hanging frame, and the detection assembly is used to detect the position of the sliding seat so that when the position of the sliding seat exceeds a first preset position, the detection assembly is used to adjust the displacement speed of the hanging frame to adjust the relative position between the hanging frame and the automobile conveyor plate chain, and when the position of the sliding seat exceeds a second preset position, the hanging frame and the automobile conveyor plate chain stop.
[0006] By adopting the above technical solution, one end of the hanging frame is installed on the online accompanying filling machine, and the other end is slidably connected to the sliding seat. On the one hand, the setting of the sliding seat enables the barrel mounting mechanism connected to multiple filling gun barrels and limiting the displacement of multiple filling gun barrels to be slidably connected to the hanging frame, so that the online accompanying filling machine can carry out accompanying filling of the car on the conveyor plate chain through the filling gun barrel. On the other hand, the sliding seat is set to be able to contact with the detection component, that is, when the synchronous movement between the online accompanying filling machine and the automobile conveyor plate chain produces a movement offset, a deviation is synchronously generated between the filling gun and the vehicle filling port, thereby causing the filling gun to abut against the vehicle filling port. The contact force is further transmitted to the filling gun barrel connected to the filling gun, and then the filling gun barrel drives the barrel mounting mechanism connected to it to move, and then the barrel mounting mechanism drives the slide seat to move laterally along the lifting frame until the slide seat contacts the detection component, and then the detection component controls the filling machine to adjust the speed accordingly according to the offset direction of the slide seat or feeds back to the filling machine and conveyor chain control system to directly stop the filling machine and conveyor chain from running, and then manually control the online accompanying filling machine and the automobile conveyor chain to reset and synchronize, effectively avoiding damage to the vehicle filling port or the filling gun and the filling gun barrel due to large deviation.
[0007] Optionally, the universal gun barrel anti-pull structure also includes a blowing mechanism and a blowing pipe, the blowing mechanism includes a sleeve and a piston, the piston is sealingly and slidingly connected to the sleeve, the sleeve is fixed to the side of the lifting frame, and the piston is connected to the sliding seat; the blowing pipes are arranged in multiple groups, and one end of the blowing pipes is connected to the air outlet end of the sleeve, the air outlet end of one group of the blowing pipes is facing the detection end of the detection component, the air outlet end of one group of the blowing pipes is facing the preset position, and the air outlet end of another group of the blowing pipes is facing the movable buffer component.
[0008] By adopting the above technical solution, the air flow of the blowing mechanism does not require an additional power source. Instead, the inherent reciprocating motion generated by the sliding seat each time it slides due to offset is directly used to drive the blowing mechanism to blow and clean synchronously, thereby preventing impurities from interfering with the functions of the sliding seat, the lifting frame and the mobile buffer assembly, ensuring that key components continue to remain clean during operation, and realizing the functional integration of passive anti-pull protection and active cleaning protection, effectively improving the reliability and service life of the entire system.
[0009] Optionally, the air outlet ends of the air blowing pipes are staggered, and the air flows blown out flow along the length direction of the hanging frame and the movable buffer assembly.
[0010] By adopting the above technical solution, the air outlet ends of the air blowing pipes are staggered so that the sweeping areas of the air flows blown out from each air outlet end are staggered and covered in a plane perpendicular to the length direction. The air flows work independently without interfering with each other, effectively concentrating the air flow energy to ensure that the pollutants are completely blown out. The blown air flow is set to flow along the length direction so that the flow direction of the air flow is consistent with the accumulation direction of the pollutants. Impurities such as dust and metal debris distributed along the length direction of the first sliding contact surface can be continuously pushed away, or impurities such as dust and metal debris distributed along the length direction of the second sliding contact surface when the elastic part is compressed can be continuously pushed away. At the same time, the air flow flowing along the length direction will completely blow away the impurities located on the first sliding contact surface or the second sliding surface along one side of the sliding contact surface, thereby ensuring smooth sliding of the sliding seat and free expansion and contraction of the spring, effectively improving the response speed of the anti-pull structure.
[0011] Optionally, the sliding seat includes a sliding plate and a slider, and the barrel mounting mechanism is detachably connected to the bottom of the sliding plate; the slider includes a first slider and a second slider, one end of the first slider and the second slider is fixed to the sliding plate, the other end of the first slider is slidably connected to the hanging frame, and the other end of the second slider is slidably connected to the movable buffer assembly, so that the barrel mounting mechanism can be displaced along the length direction of the hanging frame.
[0012] By adopting the above technical solution, the sliding seat is used as an intermediate connecting piece to connect the barrel mounting mechanism, the hanging frame and the movable buffer assembly. A first slider is set to be connected to the hanging frame so that the sliding plate can slide freely along the length direction of the hanging frame, thereby adapting to the movement offset caused by the asynchronous movement between the online accompanying filling machine and the automobile conveyor plate chain. A second slider is set to be linked with the buffer assembly to convert the abnormal pulling force caused by the asynchronous movement offset into a controllable sliding of the sliding seat on the mounting frame and the movable buffer assembly, and the pulling force is transmitted to the buffer assembly, which then buffers the pulling force when it arrives. After the pulling force dissipates, the sliding seat is driven to drive the barrel mounting mechanism to return to the preset position. The detachable setting of the sliding plate facilitates replacement of parts when they are damaged, effectively improving the flexibility of the conveyor plate chain.
[0013] Optionally, the movable buffer assembly includes a connecting rod, an elastic member, a limiting sleeve and a limiting member, the connecting rod is fixedly connected to the lifting frame and is arranged along the length direction of the lifting frame; there are multiple elastic members, and they are all sleeved along the length direction of the connecting rod, the elastic member limits the position of the second slider on the connecting rod and provides a buffering reset force so that the sliding seat is in a preset position under normal circumstances; there are multiple limiting sleeves, all of which are installed on both sides of the second slider and slidably sleeved along the length direction of the connecting rod, the limiting sleeves all abut against the elastic member, and the limiting sleeves near both sides of the second slider are embedded in both sides of the second slider and abut against its inner wall, so that the sliding seat is slidably connected to the connecting rod through the second slider; there are multiple limiting members, all of which are installed at the limiting sleeve away from the second slider and located on the side opposite to the elastic member, and the limiting member abuts against the limiting sleeve.
[0014] By adopting the above technical solution, the connecting rod provides rigid support and linear sliding guide for the elastic part and the limiting sleeve, ensuring that the elastic part and the limiting sleeve move in a preset direction, and the elastic part is used as the core buffer element. The elastic deformation of the elastic part absorbs and buffers the displacement impact caused by the sliding seat being pulled by the barrel, and generates reverse elastic force elastic reset to drive the sliding seat to reset. A plurality of limiting sleeves are provided as intermediaries for transmitting force, so as to transmit the displacement of the second slider to the elastic part and then compress or stretch the elastic part, and at the same time constrain the sliding of the elastic part along the radial position to avoid the deviation of the moving trajectory of the elastic part. The setting of the limiting part limits the maximum deformation of the elastic part, that is, the maximum compression of the elastic part, to avoid overload failure of the elastic part while defining the range of the preset position of the sliding seat. Through the hierarchical structure of connecting rod guidance, limiting sleeve force transmission, elastic part buffer reset and limiting part positioning, the mechanical buffering of the mobile buffer component and the active detection of the detection component are combined, effectively improving the safety and stability of the online accompanying filling machine.
[0015] Optionally, the detection component includes a detection switch, which is arranged on the lifting frame and is used to detect whether the sliding board is located at the first preset position of the detection switch. When the position of the sliding seat exceeds the first preset position, the displacement speed of the lifting frame is adjusted to adjust the relative position between the lifting frame and the automobile conveyor plate chain.
[0016] By adopting the above technical solution, the position of the sliding plate is monitored by the detection switch. When the synchronization error of the conveyor plate chain is small, such as the filling gun and the filling port are only slightly misaligned, the pulling force drives the sliding seat to slide along the lifting frame, and the sliding plate slides to below the detection end of the detection switch. The detection switch sends a signal to the filling machine control system. The control system adjusts the displacement speed of the lifting frame accordingly, such as acceleration or deceleration, according to the offset direction, that is, the sliding seat slides left and right, so that the relative speed of the lifting frame and the automobile conveyor plate chain matches, and the relative position offset is gradually reduced, and finally the sliding plate returns to the preset position, so that the filling gun and the filling port are realigned, and the synchronization error is corrected by dynamically adjusting the speed to avoid production interruptions caused by direct shutdown due to small offsets, thereby effectively improving production efficiency.
[0017] The detection component also includes a roller travel switch, which is arranged on the hanging frame and is used to detect whether the slide plate is located at the second preset position of the roller travel switch. When the position of the slide seat exceeds the second preset position, the hanging frame and the automobile conveyor plate chain stop.
[0018] By adopting the above technical solution, the maximum offset between the online accompanying filling machine and the automobile conveyor plate chain is limited by the roller travel switch. When the sliding plate slides along the lifting frame to the position touching the switch arm on the roller travel switch, a signal is sent to the control system of the filling machine and the automobile conveyor plate chain to immediately stop the operation of the online accompanying filling machine and the automobile conveyor plate chain, thereby avoiding deformation of the filling port or breakage of the filling gun barrel caused by continuous contact between the filling gun and the filling port. When extreme offset occurs between the high-reliability online accompanying filling machine and the automobile conveyor plate chain, the machine is forced to stop through the mechanical triggering of the roller travel switch to ensure production safety.
[0019] Optionally, the gun barrel mounting mechanism includes a lifting channel steel and a fixture, wherein the four end faces of the lifting channel steel are symmetrically provided with lifting grooves, which are fixedly connected to the bottom of the sliding seat through the top lifting groove so as to move along the lifting frame with the sliding seat; the fixture is fixed in the lifting groove at the bottom of the lifting channel steel and is arranged along the length direction of the lifting channel steel, and is used to fix and lift multiple gun barrels so that the extension direction of the gun barrel is perpendicular to the sliding direction of the sliding seat.
[0020] By adopting the above technical solution, the lifting channel steel is fixedly connected to the bottom of the slide seat through the top lifting slot, so that the lifting channel steel can slide synchronously with the slide seat along the lifting frame. When the gun barrel is subjected to lateral pulling force, the force is transmitted to the slide seat through the lifting channel steel, driving the slide seat to move left or right along the lifting frame to trigger the mobile buffer component to buffer or trigger the detection component to detect the position of the slide plate. Symmetrical slots are set on the four end faces to provide the gun barrel mounting mechanism with the possibility of multi-directional and multi-component installation, effectively improving the installation flexibility of the gun barrel mounting mechanism, and the setting of the fixer stably and effectively fixes multiple gun barrels to ensure that they are aligned with the conveyor plate chain. At the same time, the pulling force on the gun barrel is transmitted to the lifting channel steel and finally transmitted to the slide seat by the lifting channel steel to drive the slide seat to slide along the lifting frame to trigger the mobile buffer component to buffer energy absorption or trigger the detection component to determine whether to shut down.
[0021] Optionally, the fixture includes a fixing block and a fixing piece, and the fixing blocks are symmetrically arranged in two, and one side of the two fixing blocks facing each other is recessed inward to form a groove for fixing and limiting the gun barrel; the fixing piece passes through the two symmetrically arranged fixing blocks and is connected to the lifting slide to adjust the size of the groove so that the fixture can adapt to gun barrels of various sizes.
[0022] By adopting the above technical solution, the inwardly recessed grooves provided on the opposite sides of the two fixing blocks fit into the outer surface of the gun barrel, and the grooves limit the gun barrel and disperse the clamping force on the gun barrel, thereby avoiding deformation of the gun barrel caused by local stress concentration. At the same time, the limiting effect of the grooves prevents the gun barrel from shaking laterally due to vibration during the filling process, thereby causing alignment errors of the filling port. A fixing piece is provided that passes through the two fixing blocks and is connected to the lifting slide of the lifting channel steel. The spacing between the two fixing blocks can be adjusted by tightening or loosening the fixing piece, thereby changing the size of the groove and enabling the groove to limit and fix gun barrels of different diameters. This eliminates the need to customize a fixture for each gun barrel, effectively reducing the production and maintenance costs of the equipment.
[0023] Optionally, the universal barrel anti-pull structure also includes a limit block, which is detachably connected to the hanging frame and is located between the hanging frame and the movable buffer assembly. When the barrel mounting mechanism is displaced along the length direction of the hanging frame, the limit block can contact the second slider to limit the displacement stroke of the sliding seat.
[0024] By adopting the above technical solution, the limit block is installed on the lifting frame, and a safety gap is reserved between the initial position of the limit block and the second slider. The safety gap is greater than the maximum allowable compression of the elastic part of the movable buffer assembly, so that when the displacement generated by the buffering energy absorption of the elastic part is within the normal offset range, the second slider will not contact the limit block, thereby avoiding interference with the normal operation of the movable buffer assembly. When the synchronous offset of the conveyor chain is too large, the pulling force exceeds the maximum buffering capacity of the elastic part, and the sliding seat drives the second slider to slide along the connecting rod of the movable buffer assembly, compressing the elastic part to the limit position. At this time, the elastic part is restricted by the limit sleeve and the limit part and cannot continue to be compressed. At this time, if the pulling force is still not eliminated, that is, the detection assembly does not trigger the shutdown in time, the second slider will continue to move toward the limit block until it abuts against the limit block, and then the rigid structure of the limit block physically blocks the sliding of the second slider to terminate the displacement of the sliding seat, so as to avoid the barrel being broken or the filling port being deformed by collision.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. When the synchronous movement between the online accompanying filling machine and the automobile conveyor plate chain produces movement deviation, the detection component can control the filling machine to accelerate or decelerate to adjust the relative position between the filling machine and the automobile conveyor plate chain, or the detection component can control the filling machine and the conveyor plate chain to directly stop running, and manually control the online accompanying filling machine and the automobile conveyor plate chain to reset synchronization, so as to avoid damage to the vehicle filling port or the filling gun and filling gun barrel caused by large deviation.
[0027] 2. The air blowing mechanism does not require an additional power source to generate airflow. Instead, it directly utilizes the inherent reciprocating motion generated by the sliding seat each time it slides due to offset to drive the air blowing mechanism to blow and clean synchronously, thereby preventing impurities from interfering with the functions of the sliding seat, lifting frame and mobile buffer assembly, ensuring that key components continue to remain clean during operation, realizing the functional integration of passive anti-pull protection and active cleaning protection, and effectively improving the reliability and service life of the entire system.
[0028] 3. Through the hierarchical structure of the mobile buffer assembly connecting rod guidance, limit sleeve force transmission, elastic part buffer reset and limit part limitation, the mechanical buffering of the mobile buffer assembly is combined with the active detection of the detection assembly, effectively improving the safety and stability of the online accompanying filling machine.

[0035] The following is combined with Figure 1-5 This application is described in further detail.
[0036] like Figure 1-Figure 3 As shown, the embodiment of the present application discloses a universal gun barrel anti-pull structure, including a hanging frame 1, a gun barrel mounting mechanism 2, a movable buffer assembly 3 and a detection assembly 4. The hanging frame 1 can move synchronously with the automobile conveyor plate chain; the bottom of the hanging frame 1 is slidably connected to a slide seat 5, and the gun barrel mounting mechanism 2 is fixed to the bottom of the slide seat 5. The gun barrel mounting mechanism 2 is used to hang multiple gun barrels, and the extension direction of the gun barrel is perpendicular to the sliding direction of the slide seat 5; the movable buffer assembly 3 is arranged between the slide seat 5 and the hanging frame 1, and the movable buffer assembly 3 is used to limit the position of the slide seat 5 on the hanging frame 1 so that the slide seat 5 is in a preset position under normal circumstances; the detection assembly 4 is arranged on the hanging frame 1, and the detection assembly 4 is used to detect the position of the slide seat 5 so as to adjust the displacement speed of the hanging frame 1 when the position of the slide seat 5 exceeds the first preset position, so as to adjust the relative position between the hanging frame 1 and the automobile conveyor plate chain, and when the position of the slide seat 5 exceeds the second preset position, the hanging frame 1 and the automobile conveyor plate chain stop.
[0037] Example 1
[0038] Continue reading Figure 1-Figure 3One end of the hanging frame 1 is installed on the online accompanying filling machine, and the other end is slidably connected to a sliding seat 5. On the one hand, the setting of the sliding seat 5 makes the barrel mounting mechanism 2 connected to multiple filling barrels and limiting the displacement of multiple filling barrels slidably connected to the hanging frame 1, so that the online accompanying filling machine can carry out accompanying filling of the car on the conveyor plate chain through the filling barrel. On the other hand, the sliding seat 5 is set to be able to contact with the detection component 4, that is, when the synchronous movement between the online accompanying filling machine and the automobile conveyor plate chain produces a movement offset, a deviation is synchronously generated between the filling gun and the vehicle filling port, thereby causing the filling gun to abut against the vehicle filling port, and the abutting force is further The information is then transmitted to the filling gun barrel connected to the filling gun, and the filling gun barrel drives the barrel mounting mechanism 2 connected thereto to move, and the barrel mounting mechanism 2 drives the slide seat 5 to move laterally along the hanging frame 1 until the slide seat 5 contacts the detection component 4, and then the detection component 4 controls the filling machine to adjust the speed accordingly according to the offset direction of the slide seat 5 or feeds back to the filling machine and conveyor chain control system to directly stop the filling machine and conveyor chain from running, and then manually control the online accompanying filling machine and the automobile conveyor chain to reset and synchronize, effectively avoiding damage to the vehicle filling port or the filling gun and the filling gun barrel due to large deviation.
[0039] like Figure 1 As shown, the slide seat 5 includes a slide plate 51 and a slider 52, and the barrel mounting mechanism 2 is detachably connected to the bottom of the slide plate 51; the slider 52 includes a first slider 521 and a second slider 522, one end of the first slider 521 and the second slider 522 are fixed to the slide plate 51, the other end of the first slider 521 is slidably connected to the hanging frame 1, and the other end of the second slider 522 is slidably connected to the moving buffer assembly 3, so that the barrel mounting mechanism 2 can be displaced along the length direction of the hanging frame 1, and the slide seat 5 is used as an intermediate connecting piece to connect the barrel mounting mechanism 2 and the hanging frame 1 and the moving buffer assembly 3, and the first slider 521 is connected to the hanging frame 1 so that the slide plate 51 It can slide freely along the length direction of the hoisting frame 1, and thus adapt to the position offset caused by the asynchronous movement between the online accompanying filling machine and the automobile conveyor plate chain. A second slider 522 is set to be linked with the mobile buffer assembly 3, and the abnormal pulling force caused by the position offset caused by the asynchronous movement is converted into a controllable sliding of the sliding seat 5 on the hoisting frame 1 and the mobile buffer assembly 3, and the pulling force is transmitted to the mobile buffer assembly 3, and then the mobile buffer assembly 3 buffers the pulling force when it comes. After the pulling force dissipates, the sliding seat 5 is driven to drive the barrel mounting mechanism 2 to return to the preset position. The detachable setting of the sliding plate 51 is convenient for replacement when the parts are damaged, effectively improving the flexibility of the conveyor plate chain.
[0040] like Figure 3As shown, the movable buffer assembly 3 includes a connecting rod 31, an elastic member 32, a limiting sleeve 33 and a limiting member 34. The connecting rod 31 is fixedly connected to the hanging frame 1 and is arranged along the length direction of the hanging frame 1; there are multiple elastic members 32, and they are all sleeved along the length direction of the connecting rod 31. The elastic member 32 limits the position of the second slider 522 on the connecting rod 31 and provides a buffering reset force so that the sliding seat 5 is in a preset position under normal conditions; there are multiple limiting sleeves 33, all of which are installed on both sides of the second slider 522 and are slidably sleeved along the length direction of the connecting rod 31. The limiting sleeves 33 are all in contact with the elastic member 32 and are close to the second slider 522. The limiting sleeves 33 on both sides of the slider 522 are embedded in both sides of the second slider 522 and abut against its inner wall, so that the sliding seat 5 is slidably connected to the connecting rod 31 through the second slider 522; a plurality of limiting members 34 are provided, all of which are installed at the limiting sleeve 33 away from the second slider 522 and are located on the side opposite to the elastic member 32, and a plurality of limiting members 34 abut against the limiting sleeve 33, using the connecting rod 31 as the installation base and sliding guide rod of the elastic member 32, the limiting sleeve 33 and the limiting member 34, while providing rigid support for the elastic member 32, the limiting sleeve 33 and the limiting member 34, and rigidly constraining the elastic member 32, the limiting sleeve 33 and the limiting member 34. The positioning member 34 moves in a preset direction. Under normal circumstances, the elastic member 32 is in a pre-compression or pre-tensioned state, pushing the limiting sleeve 33, and applying a symmetrical pre-tightening force to the second slider 522 through the limiting sleeves 33 on both sides. The second slider 522 is embedded in the limiting sleeves 33 on both sides thereof and limited in the preset position, thereby maintaining the sliding seat 5 in the preset position, and then limiting the filling barrel through the barrel mounting mechanism 2 fixed to the sliding plate 51 to ensure that the filling barrel is aligned with the vehicle filling port. When the second slider 522 deviates from the preset position due to tension, the pulling force is transmitted to the sliding plate 51 of the sliding seat 5 through the barrel mounting mechanism 2, driving the sliding plate 51 along the hoisting The frame 1 slides, and the sliding plate 51 drives the second sliding block 522 to move synchronously. When the second sliding block 522 moves to one side, such as to the left side, the limiting sleeve 33 on the left is pushed by the second sliding block 522 to slide along the connecting rod 31, thereby compressing the elastic member 32 on the left side. When the elastic member 32 is compressed, a reverse elastic force is generated to counteract the pulling force, thereby slowing down the accelerated displacement of the sliding seat 5 and avoiding damage to the barrel or the filling port caused by a hard collision. At the same time, multiple elastic members 32 are provided and the multiple elastic members 32 are arranged in sections along the connecting rod 31 to form a stepped buffer. The elastic members 32 in different sections will be compressed in sequence to gradually absorb the impact energy, effectively avoiding single-point overload failure.
[0041] like Figure 1 and Figure 3As shown, if the movement deviation between the filling machine and the conveyor plate chain is too large, resulting in excessive pulling force, the sliding seat 5 drives the second sliding block 522 to continuously compress the elastic member 32 on one side until the multiple limiting sleeves 33 on that side are pushed to abut against the limiting member 34. At this time, the elastic member 32 reaches the maximum deformation and is limited by the limiting member 34 to the compression degree and cannot be compressed any further. The displacement of the sliding seat 5 is forcibly limited and cannot continue to slide. At this time, the position of the sliding seat 5 exceeds the preset range, and the corresponding trigger detection component 4 controls the conveyor plate chain to stop running, so as to avoid damage to the filling port or the barrel due to continuous pulling. When the synchronization error is eliminated and the pulling force disappears, the compressed elastic member 32 releases its elastic potential energy, and the limiting member 34 provides a support point for the force of the elastic member 32 to reset. The limiting sleeve 33 is pushed by the elastic member 32 to reset the second sliding block 522, and the elastic forces of the elastic members 32 on both sides are rebalanced, driving the sliding seat 5 back to the initial preset position, and preparing for alignment for the next filling.
[0042] like Figure 1 and Figure 2 As shown, the detection component 4 includes a detection switch 41, which is set on the hanging frame 1 and is used to detect whether the sliding plate 51 is at the first preset position of the detection switch 41. When the position of the sliding seat 5 exceeds the first preset position, the displacement speed of the hanging frame 1 is adjusted to adjust the relative position between the hanging frame 1 and the automobile conveyor plate chain. The position of the sliding plate 51 is monitored by the detection switch 41. When the synchronization error of the conveyor plate chain is small, such as the filling gun and the filling port are only slightly misaligned, the pulling force drives the sliding seat 5 to slide along the hanging frame 1, and the sliding plate 51 slides to Below the detection end of the detection switch 41, the detection switch 41 sends a signal to the filling machine control system. The control system adjusts the displacement speed of the hoisting frame 1 accordingly, such as acceleration or deceleration, according to the offset direction, that is, the direction in which the sliding seat 5 slides to the left or right, so that the relative speed of the hoisting frame 1 matches that of the automobile conveyor plate chain, and the relative position offset is gradually reduced, and finally the sliding plate 51 returns to the preset position, so that the filling gun and the filling port are realigned, and the synchronization error is corrected by dynamically adjusting the speed to avoid production interruptions caused by direct shutdown due to small offsets, thereby effectively improving production efficiency.
[0043] like Figure 1 and Figure 2As shown, the detection component 4 also includes a roller travel switch 42 and a switch arm 43 located on the roller travel switch 42. The roller travel switch 42 is arranged on the hoisting frame 1, and is used to detect whether the sliding plate 51 is at the second preset position of the roller travel switch 42. When the position of the sliding seat 5 exceeds the second preset position, the hoisting frame 1 and the automobile conveyor plate chain stop, and the roller travel switch 42 limits the maximum offset between the online accompanying filling machine and the automobile conveyor plate chain. When the sliding plate 51 slides along the hoisting frame 1 to the position of touching the switch arm 43 on the roller travel switch 42, the roller travel switch 42 alarms and sends a signal to the control system of the online accompanying filling machine and the automobile conveyor plate chain, immediately stopping the operation of the online accompanying filling machine and the automobile conveyor plate chain, avoiding deformation of the filling port or breakage of the filling gun barrel caused by continuous contact between the filling gun and the filling port, and forcing the machine to stop when extreme offset occurs between the high-reliability online accompanying filling machine and the automobile conveyor plate chain through mechanical triggering of the roller travel switch 42 to ensure production safety.
[0044] Specifically, the number of detection switches 41 and roller travel switches 42 is set to two, and the two detection switches 41 and the two roller travel switches 42 are all set on the same side of the lifting frame 1. The area between the two detection switches 41 is defined as the first preset position, and the area between the two roller travel switches 42 is defined as the second preset position. When the position of the sliding seat 5 exceeds the left side of the first preset position, it means that the displacement speed of the lifting frame 1 is lower than the speed of the automobile conveyor plate chain, and the displacement acceleration of the lifting frame 1 is adjusted accordingly to match the relative speed of the lifting frame 1 and the automobile conveyor plate chain, and gradually reduce the relative position offset between the lifting frame 1 and the automobile conveyor plate chain, and finally return the sliding plate 51 to the preset position, so that the filling gun is realigned with the filling port. When the position of the sliding seat 5 exceeds the right side of the first preset position, it means that the displacement speed of the lifting frame 1 is higher than the speed of the automobile conveyor plate chain, and the lifting frame 1 is adjusted accordingly. The speed is reduced to match the relative speed of the hoisting frame 1 and the automobile conveyor plate chain, and the relative position offset between the hoisting frame 1 and the automobile conveyor plate chain is gradually reduced, and finally the sliding plate 51 returns to the preset position, so that the filling gun is realigned with the filling port. Similarly, when the sliding plate 51 has exceeded the first preset position but continues to slide along the hoisting frame 1 until it touches the switch arm 43 on the left roller travel switch 42 or the switch arm 43 on the right roller travel switch 42, it corresponds to the displacement speed of the hoisting frame 1 being too low or too high at this time, and the maximum offset between the online accompanying filling machine and the automobile conveyor plate chain has been reached. The roller travel switch 42 alarm sends a signal to the control system of the filling machine and the automobile conveyor plate chain, immediately stopping the operation of the filling machine and the automobile conveyor plate chain to avoid continuous contact between the filling gun and the filling port or sudden impact causing deformation of the filling port or breakage of the filling gun barrel, thereby ensuring production safety.
[0045] Optionally, the gun barrel mounting mechanism 2 includes a lifting channel steel 21 and a fixture 22. The four end surfaces of the lifting channel steel 21 are symmetrically provided with lifting grooves 211, and are fixedly connected to the bottom of the slide seat 5 through the top lifting groove 211, so as to move along the lifting frame 1 with the slide seat 5; the fixture 22 is fixed in the lifting groove 211 at the bottom of the lifting channel steel 21 and is arranged along the length direction of the lifting channel steel 21, and is used to fix and lift multiple gun barrels so that the extension direction of the gun barrel is perpendicular to the sliding direction of the slide seat 5, so that the lifting channel steel 21 is fixedly connected to the bottom of the slide seat 5 through the top lifting groove 211, so that the lifting channel steel 21 can slide synchronously with the slide seat 5 along the lifting frame 1, and when the gun barrel is subjected to a lateral pulling force, the force is transmitted through the lifting groove 211. The channel steel 21 is transmitted to the slide seat 5, driving the slide seat 5 to move left or right along the hanging frame 1 to trigger the mobile buffer component 3 to buffer or trigger the detection component 4 to detect the position of the slide plate 51. Symmetrical slide grooves are set on the four end faces to provide the barrel mounting mechanism 2 with the possibility of multi-directional and multi-component installation, effectively improving the installation flexibility of the barrel mounting mechanism 2, and the setting of the fixer 22 stably and effectively fixes multiple barrels to ensure that they are aligned with the conveyor plate chain. At the same time, the pulling force on the barrel is transmitted to the hanging channel steel 21 and finally transmitted to the slide seat 5 by the hanging channel steel 21 to drive the slide seat 5 to slide along the hanging frame 1 to trigger the mobile buffer component 3 to buffer and absorb energy or trigger the detection component 4 to determine whether to shut down.
[0046] like Figure 2 As shown, the holder 22 includes a fixing block 221 and a fixing member 222. The fixing blocks 221 are symmetrically arranged in two, and one side of the two fixing blocks facing each other is recessed inward to form a groove 223 for fixing and limiting the position of the gun barrel; the fixing member 222 passes through the two symmetrically arranged fixing blocks 221 and is connected to the lifting slide 211, so that the size of the groove 223 can be adjusted to make the holder 22 adapt to gun barrels of various sizes. The inwardly recessed grooves 223 set on the opposite sides of the two fixing blocks 221 fit the outer surface of the gun barrel, and the grooves 223 limit the position of the gun barrel and disperse the clamping force on the gun barrel. , avoiding deformation of the barrel caused by local stress concentration. At the same time, the limiting effect of the groove 223 prevents the barrel from shaking laterally due to vibration during the filling process, thereby causing alignment error of the filling port. A fixing piece 222 is set to pass through the two fixing blocks 221 and connected to the lifting slide groove 211 of the lifting channel steel 21, and then the distance between the two fixing blocks 221 is adjusted by tightening or loosening the fixing piece 222, thereby changing the size of the groove 223 and enabling the groove 223 to limit and fix barrels of different diameters, thereby eliminating the need to customize the holder 22 for each barrel, effectively reducing the equipment production and maintenance costs.
[0047] like Figure 1 and Figure 3As shown, the universal gun barrel anti-pull structure also includes a limit block 6, which is detachably connected to the hanging frame 1 and is located between the hanging frame 1 and the movable buffer assembly 3. When the gun barrel mounting mechanism 2 is displaced along the length direction of the hanging frame 1, the limit block 6 can contact the second slider 522 to limit the displacement stroke of the sliding seat 5. The limit block 6 is installed on the hanging frame 1, and a safety gap is reserved between the initial position of the limit block 6 and the second slider 522. The safety gap is greater than the maximum allowable compression of the elastic member 32 of the movable buffer assembly 3, so that when the displacement generated by the buffering energy absorption of the elastic member 32 is within the normal offset range, the second slider 522 will not contact the limit block 6 to avoid interference with the movement. The dynamic buffer assembly 3 works normally, and when the synchronous offset of the conveyor plate chain is too large, the pulling force exceeds the maximum buffering capacity of the elastic member 32, and the sliding seat 5 drives the second slider 522 to slide along the connecting rod 31 of the mobile buffer assembly 3, compressing the elastic member 32 to the limit position. At this time, the elastic member 32 is restricted by the limiting sleeve 33 and the limiting member 34 and cannot continue to be compressed. At this time, if the pulling force is still not eliminated, that is, the detection assembly 4 does not trigger the shutdown in time, the second slider 522 will continue to move toward the limit block 6 until it abuts against the limit block 6, and then the rigid structure of the limit block 6 physically blocks the sliding of the second slider 522 to terminate the displacement of the sliding seat 5, so as to avoid the barrel being pulled off or the filling port being deformed by the collision.
[0048] The implementation principle of the first embodiment of the present application is as follows: one end of the hanging frame 1 is installed on the online accompanying filling machine, and the other end is slidably connected to the sliding seat 5. On the one hand, the setting of the sliding seat 5 enables the barrel mounting mechanism 2 connected to multiple filling barrels and limiting the displacement of multiple filling barrels to be slidably connected to the hanging frame 1, so that the online accompanying filling machine can carry out accompanying filling of the car on the conveyor plate chain through the filling barrel. On the other hand, the sliding seat 5 is set to be able to contact with the detection component 4, that is, when the synchronous movement between the online accompanying filling machine and the automobile conveyor plate chain produces a movement offset, the filling gun and the vehicle filling port are synchronously generated. Deviation, thereby causing the filling gun to abut against the vehicle's filling port, and the abutting force is further transmitted to the filling gun barrel connected to the filling gun, and then the filling gun barrel drives the barrel mounting mechanism 2 connected to it to move, and then the barrel mounting mechanism 2 drives the slide seat 5 to move laterally along the lifting frame 1 until the slide seat 5 contacts the detection component 4, and then the detection component 4 controls the filling machine to adjust the speed accordingly according to the deviation direction of the slide seat 5 or feeds back to the filling machine and conveyor plate chain control system to directly stop the filling machine and conveyor plate chain from running, and then manually control the online accompanying filling machine and the automobile conveyor plate chain to reset synchronization.
[0049] Example 2
[0050] See also Figure 4 and Figure 5 The difference between this embodiment and the first embodiment is that the universal barrel anti-pull structure further includes a blowing mechanism 7 and a blowing pipe 8.
[0051] See also Figure 4 and Figure 5 The air blowing mechanism 7 includes a sleeve 71 and a piston 72. The piston 72 is sealingly and slidably connected to the sleeve 71. The sleeve 71 is fixed to the side of the hanging frame 1, and the piston 72 is connected to the sliding seat 5. There are multiple groups of air blowing pipes 8, and one end of the multiple groups of air blowing pipes 8 is connected to the air outlet end of the sleeve 71. The air outlet end of one group of air blowing pipes 8 is directed toward the detection end of the detection component 4, the air outlet end of one group of air blowing pipes 8 is directed toward the first preset position, and the air outlet end of the other group of air blowing pipes 8 is directed toward the mobile buffer component 3. When a synchronous offset occurs between the filling machine and the conveyor plate chain, the sliding seat 5 slides left or right along the hanging frame 1. When the cam 72 is in the airtight position, the air in the cam 72 is released, and the air in the cam 72 is released from the intake port, and the intake port 72 is released, and the intake port 72 is released. The air outlet of one set of air blowing pipes 8 is directed toward the preset position on the hanging frame 1, so that the air flow blows toward the first sliding contact surface between the sliding seat 5 and the hanging frame 1, and removes the oil, dust, metal debris and other impurities on the sliding contact surface, reduces the friction resistance of the sliding seat 5 when sliding, ensures the smooth displacement of the sliding seat 5, and avoids the delay of the triggering of the detection component 4 due to the inability to transmit the pulling force in time due to the jamming, and sets the air outlet of another set of air blowing pipes 8 toward the mobile buffer component 3, so that the air flow blows into the elastic member. The gap between the limiting sleeve 33 and the connecting rod 31 is cleaned to remove dust and debris in the gap to prevent dust, metal debris and other impurities from accumulating in the gap and causing the elastic member 32 to be stuck due to impurities and unable to be compressed or reset normally. At the same time, the air flow can also blow to the second sliding contact surface between the limiting sleeve 33 and the connecting rod 31 to remove oil, dust, metal debris and other impurities on the sliding contact surface between the limiting sleeve 33 and the connecting rod 31, thereby reducing the sliding friction between the limiting sleeve 33 and the connecting rod 31 and avoiding the failure of the buffering force caused by the limiting sleeve 33 being stuck and unable to compress the elastic member 32.
[0052] Continue reading Figure 4 and Figure 5The air outlet ends of the blowing pipes 8 are staggered, and the air flows out along the length direction of the lifting frame 1 and the movable buffer assembly 3. The air outlet ends of the blowing pipes 8 are staggered, so that the sweeping areas of the air flows blown out of each air outlet end are staggered and covered in a plane perpendicular to the length direction. The air flows work independently without interfering with each other, effectively concentrating the air flow energy, ensuring that the pollutants are completely blown out, and the blown air flow is set to flow along the length direction so that the flow direction of the air flow is consistent with the accumulation direction of the pollutants, which can continuously push away impurities such as dust and metal debris distributed along the length direction of the first sliding contact surface, or continuously push away impurities such as dust and metal debris distributed along the length direction of the second sliding contact surface when the elastic member 32 is compressed. At the same time, the air flow flowing along the length direction will completely blow away the impurities located on the first sliding contact surface or the second sliding surface along one side of the sliding contact surface, thereby ensuring smooth sliding of the sliding seat 5 and free expansion and contraction of the elastic member, effectively improving the response speed of the anti-pull structure.
[0053] Among them, the sleeve 71 is configured to have an intake port for inhaling air flow and a return valve arranged at the intake port at the top. The return valve opens accordingly when the sleeve 71 inhales air flow, and closes accordingly when the sleeve 71 discharges air flow. Specifically, the blowing mechanism 7 drives the piston 72 to move back and forth inside the sleeve 71 through the reciprocating motion of the sliding seat 5, and then inhales external air through the intake port opened at the top of the sleeve 71, and then discharges air from the air outlet end of the blowing pipe 8 to clean impurities located at the detection end, the first sliding contact surface or the second sliding contact surface of the detection component 4.
[0054] The implementation principle of the second embodiment of the present application is as follows: the sleeve 71 is provided with a suction port for inhaling air flow and a return valve arranged at the suction port at the top. The return valve opens accordingly when the sleeve 71 inhales air flow, and closes accordingly when the sleeve 71 discharges air flow. Specifically, the blowing mechanism 7 drives the piston 72 to move back and forth inside the sleeve 71 through the reciprocating motion of the first slider 521, and then inhales external air through the suction port opened at the top of the sleeve 71, and then discharges air from the air outlet end of the blowing pipe 8 to clean the impurities located at the detection end, the first sliding contact surface or the second sliding contact surface of the detection component 4, to avoid impurities blocking or falsely triggering the detection component 4 signal due to blocking or interfering with the functions of the sliding seat 5, the lifting frame 1 and the moving buffer component 3, to ensure that the key components continue to maintain a clean state during operation, and realize the functional integration of passive anti-pull protection and active cleaning protection, effectively improving the reliability and service life of the entire system.
[0055] 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.
