Description

Technical Field

[0001] The invention belongs to the technical field of pharmaceuticals, and in particular relates to an ampoule filling system. Background Art

[0002] The ampoule sealing machine is mainly used to fill standard solutions, liquid medicines, etc. into ampoules and melt and seal the bottle mouth.

[0003] Existing ampoule sealing machines primarily consist of a control box and a sealing operation table or assembly line consisting of a filling, clamping, and flame heating device. Standard liquids, medicinal solutions, and other substances are injected into the ampoule via the filling device. The flame heating device heats the upper end of the ampoule for a specified period of time, automatically sealing it or using a gripper to perform wire drawing and sealing. The entire equipment is large, and the entire process requires one or two workers to continuously operate according to operating specifications, consuming a significant amount of manpower. This results in low production efficiency and difficulty ensuring consistent sealing.

[0004] At the same time, since the new sealing machine has a more compact structure and the turntable type has a higher time requirement for the coordination of the surrounding components, a system that matches the new sealing machine is urgently needed. Summary of the Invention

[0005] In response to the problems existing in the background technology, the present invention provides an ampoule filling system, characterized in that it includes: a main frame, an auger mechanism, a wire drawing mechanism, a pumping mechanism, a flame system, a friction mechanism, and a bottle collecting mechanism, wherein the auger mechanism, the turntable mechanism, the wire drawing mechanism, the pumping mechanism, the flame system, the friction mechanism, and the bottle collecting mechanism are all installed on the main frame;

[0006] The turntable mechanism includes: a working base surface, a rotating indexing plate, a reducer, a turntable drive motor, a circular loading platform and a bottle rotation stabilization group, wherein the working base surface is mounted above the frame via a bracket, the output shafts of the circular loading platform and the reducer are connected to the rotating part of the rotating indexing plate from the upper and lower directions, the base of the rotating indexing plate is fixed to the working base surface, and the bottle rotation stabilization group is evenly mounted on the outer periphery of the upper end surface of the circular loading platform; the input shaft of the reducer is connected to the output shaft of the turntable drive motor; and the turntable drive motor is mounted below the working base surface via a bracket;

[0007] Along the rotation direction of the circular loading platform, the outlet of the single conveying channel in the auger mechanism, the nozzle of the pump mechanism, the first flame nozzle of the flame system, the second flame nozzle of the flame system, and the bottle hook plate group of the bottle collecting mechanism are arranged in sequence. In the direction opposite to the second flame nozzle of the flame system, a gripper of the wire drawing mechanism is also arranged. Friction rotation mechanisms are arranged at the radial position where the nozzle is located, the radial position opposite to the first flame nozzle, and the radial position opposite to the second flame nozzle of the flame system.

[0008] The PLC is installed in the main frame, and a control system is installed in the PLC. The control system includes: a timer module, a turntable rotation module, an auger rotation module, a filling needle control module, a wire drawing mechanism moving module and a flame mechanism lifting module, wherein the timer module is respectively connected to the turntable rotation module, the auger rotation module, the filling needle control module, the wire drawing mechanism moving module, the flame mechanism lifting module and the turntable sensor, the nozzle bottom lowering sensor and the gripper top lifting sensor; the turntable rotation module is connected to the turntable drive motor through the turntable relay; the auger rotation module is connected to the auger motor in the auger mechanism through the auger relay; the filling needle control module is connected to the hydraulic lifting device in the pump mechanism through the nozzle lifting relay; the flame mechanism lifting module is connected to the lifting cylinder in the flame system through the flame lifting relay; the wire drawing mechanism moving module is connected to the gripper driving cylinder of the wire drawing mechanism through the gripper driving cylinder relay, the wire drawing mechanism moving module is connected to the lifting mechanism of the wire drawing mechanism through the lifting mechanism relay, and the wire drawing mechanism moving module is connected to the wire drawing power mechanism through the wire drawing power mechanism relay;

[0009] The timer module checks the electrical signals returned by each relay. If the relay is in place or returns abnormally, the entire process is stopped and displayed on the multi-function touch screen. The timer module is equipped with an independent time axis, which includes even and odd positions.

[0010] After the turntable sensor detects that the turntable has stopped, it sends a turntable stop signal to the timer module; after receiving the turntable stop signal, the timer module confirms the turntable position, and after confirming that the turntable is in place, it checks with the work position of the timer module; when the pointer in the timer module is in the even position, the timer module sends an even position confirmation signal B to the auger rotation module, the filling needle control module and the flame mechanism lifting module; when the pointer in the timer module is in the odd position, the timer module sends an odd position confirmation signal C to the auger rotation module;

[0011] After the nozzle bottom drop sensor detects that the lifting cylinder has dropped, it sends a wire drawing start signal to the timer module. The timer module then sends a wire drawing start signal D to the wire drawing mechanism moving module. At this time, the wire drawing mechanism moving module should be in the waiting process after completing the gripper positioning action. After receiving the wire drawing start signal D, the wire drawing mechanism moving module starts to execute the wire drawing action.

[0012] After the gripper lift sensor detects that the gripper drive cylinder has lifted, it sends a wire drawing completion signal A to the timer module. After receiving the wire drawing completion signal A, the timer module jumps to the odd station; after the odd station reaches the set value, it automatically jumps to the even station.

[0013] A driving cycle module of the turntable rotation includes four actions: even position start, even position stop, odd position start and odd position stop. When the even position is started and the odd position is started, the turntable rotation module sends a turntable rotation signal to the turntable relay to drive the turntable drive motor to rotate. When the odd position is stopped and the even position is stopped, the turntable rotation module sends a turntable stop signal to the turntable relay to stop the rotation of the turntable drive motor.

[0014] A driving cycle of auger rotation includes two actions: auger rotation and auger stop. During the waiting process, the auger rotation module performs the auger rotation action after receiving the even-position confirmation signal B or the odd-position confirmation signal C sent by the timer module, and performs the auger stop action after the auger rotates one circle. After the auger relay returns the auger stop signal, the auger rotation module enters the waiting process. The auger rotation action is: the auger rotation module sends the auger rotation signal to the auger relay to drive the auger motor to rotate; the auger stop action is: the auger rotation module sends the auger stop signal to the auger relay to confirm that the auger motor stops; if the even-position confirmation signal B or the odd-position confirmation signal C is received during the non-waiting process, the entire device stops and an error is reported.

[0015] A single drive cycle for the filling needle control consists of four actions: nozzle positioning, nozzle injection, nozzle reset, and liquid aspiration. During the waiting phase, the filling needle control module receives an even-position confirmation signal B from the timer module, then performs nozzle positioning. After this, it performs nozzle injection, then liquid aspiration. After this, the waiting phase begins. The nozzle positioning phase involves the filling needle control module sending a nozzle positioning signal to the nozzle lift relay, driving the hydraulic lift device to lower the nozzle support frame and insert the injection nozzle into the ampoule below. The nozzle injection phase involves the filling needle control module sending a nozzle injection signal to the pump core axial motor, which drives the syringe pump to release pressure, allowing the nozzle to dispense liquid. The nozzle reset phase involves the filling needle control module sending a nozzle reset signal to the nozzle lift relay, driving the hydraulic lift device to raise the nozzle support frame and remove the injection nozzle from the ampoule. The liquid aspiration phase involves the pump core axial motor pulling the syringe pump to increase pressure, allowing the syringe pump to aspirate liquid. During the aspiration phase, the nozzle remains stationary. If an even confirmation signal B is received during the non-waiting process, the entire device will be stopped and an error will be reported.

[0016] A driving cycle of the flame mechanism lifting includes two actions: flame descending and flame ascending. During the waiting process, the flame mechanism lifting module performs the flame descending action after receiving the even position confirmation signal B sent by the timer module, and performs the flame ascending action after the flame descending action is completed. After the flame ascending action is completed, it enters the waiting process; the flame descending action is: the flame mechanism lifting module sends a flame descending signal to the flame lifting relay to push the lifting cylinder down so that the second flame nozzle descends; the nozzle descending sensor monitors the position of the nozzle fixture; the flame ascending action is: the flame mechanism lifting module sends a flame ascending signal to the flame lifting relay to push the lifting cylinder up so that the second flame nozzle ascends; if the even position confirmation signal B is received during the non-waiting process, the entire device is stopped and an error is reported.

[0017] A driving cycle of the wire drawing mechanism movement includes three actions: wire drawing, gripper throwing and gripper positioning; during the waiting process, the wire drawing mechanism moving module receives the wire drawing start signal D sent by the timer module, and then performs the wire drawing action. After the wire drawing action is completed, the gripper throwing action is performed. After the gripper throwing action is completed, the gripper positioning action is performed. After the gripper positioning action is completed, the waiting process is entered; the wire drawing action is: the wire drawing mechanism moving module sends a gripper clamping signal to the gripper drive cylinder relay to reduce the gripper spacing to clamp the ampoule bottle mouth, and then sends a wire drawing signal The lifting mechanism relay changes the gripper's height, lifting the clamped ampoule. The gripper's throwing motion involves the wire drawing mechanism's motion module sending a gripper throwing signal to the wire drawing mechanism relay, causing the mechanism's drive shaft to rotate. This signal then sends a gripper throwing signal to the gripper's drive cylinder relay, increasing the gripper's distance and allowing the ampoule's mouth to drop into the waste recycling device below. The gripper's positioning motion involves the wire drawing mechanism's motion module sending a gripper positioning signal to the wire drawing mechanism relay, driving the shaft to rotate and returning the gripper to the position above the ampoule. If a wire drawing start signal D is received during a non-waiting period, the entire system stops and an error is reported.

[0044] The turntable mechanism drives the turntable drive motor to rotate according to the set time point and stops after rotating one station angle;

[0045] Step 6: The turntable mechanism performs odd-position positioning:

[0046] Then the timer module confirms the position of the turntable after receiving the turntable stop signal, and after confirming that the turntable is in place, it checks with the workstation where the timer module is located;

[0047] At this time, the pointer in the timer module is in the odd position, and the timer module sends an odd position confirmation signal C to the auger rotation module. After the odd position reaches the set value, it automatically jumps to the even position.

[0084] The conveyor belt 207 is provided below Figure 4 and Figure 5The elastic tensioning device shown in the figure comprises: a fine-tuning fixed optical axis 209, a linear bearing 2010, a compression spring 2011, a fine-tuning locking structure 2012, a fine-tuning connecting plate 2013 and a tensioning roller 2014; wherein the tensioning roller 2014 contacts and tensions the conveyor belt 207, and the two ends of the tensioning roller 2014 are respectively connected to a fine-tuning connecting plate 2013 for rotation, and the two ends of the fine-tuning connecting plate 2013 are respectively connected to the same side through a linear bearing 2010. The fine-tuning fixed optical axis 209 is slidably connected, so that the tensioning roller 2014 can slide linearly up and down; the lower end of the fine-tuning fixed optical axis 209 is fixedly connected to the base panel 202, and a fine-tuning locking structure 2012 is installed on the upper part of each fine-tuning fixed optical axis 209. A compression spring 2011 is arranged between the fine-tuning locking structure 2012 and the fine-tuning connecting plate 2013 (linear bearing 2010) to adjust the position of the fine-tuning locking structure 2012 to adjust the tension of the conveyor belt 207.

[0085] like Figure 4 、 Figure 5 、 Figure 6 and Figure 15 The auger mechanism 4 shown in the figure includes: an auger motor 401, an auger reducer gear set 402, an auger clamping fixture 404, an auger 405, a fixing seat 407, an empty bottle baffle 408, a reflow device 409, a turntable feeding baffle group 4010, a feeding arc plate 4012, and a sliding plate 4013; wherein the auger 405 is installed above the tail of the conveying mechanism 2 (the outgoing direction above the conveyor belt 207), one end of the auger 405 is rotatably connected to an auger clamping fixture 404, and the other end of the auger 405 is connected to a fixed The fixed seat 407 is rotatably connected to form a stable structure rotating around the axis; the fixed seat 407 is integrally fixed to the sliding plate 4013, and the sliding plate 4013 and the auger clamping fixture 404 are both clamped and connected to the optical axis 201; one end of the auger 405 is connected to the auger motor 401 through the auger reducer gear set 402 to transmit torque and drive the auger 405 to rotate; the auger reducer gear set 402 is clamped and connected to the optical axis 201 through the auger clamping fixture 404; the auger motor 401 is mounted on the base panel 202 through a bracket;

[0086] The main body of the auger 405 includes a cylindrical portion 40501 and a gradually thickened portion 40502 that are integrally formed and have smooth transition boundaries. A cylindrical spiral groove 4051 for conveying empty bottles is opened on the outer periphery of the auger 405. The empty bottle conveying groove with the center as the center is divided into an equal intercept portion 40511 and an intercept gradually expanding portion 40512. The equal intercept portion 40511 is arranged outside the cylindrical portion 40501, and the bottom surface of the groove of the equal intercept portion 40511 is arc-shaped; the intercept portion 40511 is provided outside the cylindrical portion 40501. The gradually expanding portion 40512 is disposed outside the gradually thickening portion 40502. Since the intercept gradually expanding portion 40512 is also a cylindrical spiral groove, and the diameter of the gradually thickening portion 40502 gradually increases, the groove depth of the intercept gradually expanding portion 40512 also gradually increases, and the groove shape gradually changes from an arc shape to a "U" shape. The groove depth of the intercept gradually expanding portion 40512 does not exceed the diameter of the empty ampoule. The end of the intercept gradually expanding portion 40512 is the outlet end of the auger 405.

[0087] Two empty bottle baffles 408 are installed above the conveyor belt 207. The empty bottle baffles 408, which play a limiting role, are installed on the optical axis 201 through a bracket. The reflow device 409 is arranged in the two empty bottle baffles 408 and in the space above the conveyor belt 207. The reflow device 409 is fixed to the empty bottle baffles 408. The reflow device 409 is provided with a sliding inclined surface 4091 which is mainly used for dynamic optimization when a large number of ampoules move at high speed on the conveyor belt 207 to prevent multiple ampoules from entering the conveying channel at the outlet end of the auger 405, and can effectively prevent the non-export end part of the auger 405 from being crowded with ampoules due to the rapid rotation of the conveyor belt 207, resulting in the problem of ampoules tipping over; the side of the reflow device 409 facing the auger 405 is a channel plane 4092 and is close to the gradually thickened part 40502 of the auger 405; the channel plane 4092 is parallel to the axis of the auger 405;

[0088] Due to the presence of the gradually expanding intercept portion 40512, a single conveying channel is formed between the recirculator 409 and the cylindrical spiral groove 4051 of the auger 405, allowing only a single ampoule to pass through. Under the propulsion of the conveyor belt 207, the upright empty ampoules are gradually arranged along the equally intercepted portion 40511 of the empty bottle conveying cylindrical spiral groove 4051 at the far side of the outlet section. They then enter the single conveying channel and remain upright, allowing them to be fed at high speed into the subsequent section (the bottle rotation stabilization group 502 of the turntable mechanism 5) through the cooperation of the turntable feeding baffle assembly 4010 and the sliding plate 4013. The single conveying channel limits the position of the ampoules to prevent them from deviating from the intended channel.

[0089] The turntable feed baffle group 4010 located just above the sliding plate 4013 is as shown in FIG. Figure 15 and Figure 16As shown, it includes: a long straight plate 40101, a bottle pressing bar 40104, a short straight plate 40102 and a delivery hook plate 40103, wherein the long straight plate 40101 and the short straight plate 40102 which are parallel to each other are fixed to the sliding plate 4013 by bolts, the short straight plate 40102 and the long straight plate 40101 are flush with each other on one side of the auger, and are opposite to the outlet of the auger 405 (the outlet of the conveying channel), the delivery hook plate 40103 is fixed to the outside of the long straight plate 40101 in the direction of the turntable, and an ampoule bottle outlet is formed between the delivery hook plate 40103 and the short straight plate 40102, the outlet is opposite to the small turntable 5021 in the bottle rotation stabilization group 502 on the rotating indexing plate 503, and the size of the outlet is slightly larger than the width of a single ampoule bottle; a pair of bottle pressing bars 40104 are installed at the opposite positions of the long straight plate 40101 and the short straight plate 40102.

[0090] Figure 15 and Figure 16 The bottle pressing bar 40104 shown includes: a straight rail sliding portion 401041, a straight rail lifting portion 401042 and a straight rail delivery portion 401043; wherein the straight rail sliding portion 401041, the straight rail lifting portion 401042 and the straight rail delivery portion 401043 are sequentially arranged along the direction of entry of the empty ampoule bottle and are integrally formed; the height of the straight rail sliding portion 401041 is the same as the bottle shoulder of the ampoule bottle placed on the sliding plate 4013; the length of the straight rail sliding portion 401041 is not less than the width of an ampoule bottle, so that the empty ampoule bottle already between the sliding plate 4013 and the straight rail sliding portion 401041 will not be pushed upward from the bottom due to the auger outlet The inertia generated by the point push continues to move forward or fall; the empty ampoule bottle stays in an upright state at the straight rail sliding part 401041 until the bottle body of the subsequent empty ampoule bottle pushes the bottle body of the empty ampoule bottle at the straight rail sliding part 401041, so that the power for the empty ampoule bottle located at the entrance position of the turntable feeding baffle group 4010 (in this embodiment, between the sliding plate 4013 and the straight rail sliding part 401041) to move forward is changed from the point thrust from the conventional auger outlet to the thrust distributed on the entire line between the bottles, thereby solving the problem of the empty ampoule bottle tipping over due to the point thrust on the middle part of the ampoule bottle when the interval between the two empty ampoules is too large.

[0091] At the outlet of the auger 405, ampoules often fall over. According to multiple tests, the main reason is that during the movement of the empty ampoule, especially after entering the sliding plate 4013, the main friction part is at the bottom of the bottle, and the empty ampoule has a lighter weight. Therefore, each time the auger 405 rotates at the outlet, the empty ampoule is actually pushed gradually from bottom to top by the outlet edge, resulting in a large tilt of the empty ampoule when it is finally fully pushed out. Generally speaking, this tilt will be blocked by the empty ampoule already on the sliding plate 4013 and will not affect the operation of the equipment; however, it will cause tipping in the following situations: 1. Due to the mismatch between the auger and the conveyor belt, there will be a lack of empty ampoules in a certain cycle. 1. The working condition occurs, and at this time the empty ampoule bottle already on the sliding plate 4013 will continue to move forward for a distance due to inertia, so that a certain degree of space will appear between it and the auger outlet, and the empty ampoule bottle just out of the auger outlet will fall over due to tilt and inertia; 2. Because the wire drawing action requires a short static stage, all mechanisms including the auger are in an intermittent working state, resulting in the empty ampoule bottle pushed out of the auger to produce periodic violent shaking and jumping. At the moment the empty ampoule bottle is sent out from the ampoule bottle outlet of the turntable feeding baffle group 4010, the ampoule bottle in the turntable feeding baffle group 4010 will fall over (especially when running faster); 3. Due to the previous two reasons, the falling occurs when the equipment debugging work is discontinuous.

[0092] Since the straight rail sliding portion 401041 can actively adjust each empty ampoule bottle entering the turntable feeding baffle group 4010, while the straight rail lifting portion 401042 and the straight rail delivery portion 401043 continue to shake and jump stably; the empty ampoule bottle already between the sliding plate 4013 and the bottle pressing bar 40104 will not continue to move forward or fall due to inertia until the subsequent empty ampoule bottle pushes the empty ampoule bottle staying in the turntable feeding baffle group 4010 ; The driving force for the empty ampoule bottles located at the entrance of the turntable feeding baffle group 4010 (in this embodiment, between the sliding plate 4013 and the straight rail sliding part 401041) is changed from the point thrust at the conventional auger outlet to the thrust distributed along the entire line between the bottles, thereby solving all technical problems caused by the empty ampoule bottles tipping over when the auger pushes the middle part and the support point (friction part) is at the bottom of the bottle, making the feeding stable.

[0093] In this embodiment, a feeding arc plate 4012 is provided behind the ampoule bottle outlet. The feeding arc plate 4012 can be mounted on a sliding plate 4013 at a fixed angle. The feeding arc plate 4012 is used in conjunction with the next process step (turntable mechanism 5) to ensure that the position of the ampoule bottle on the small turntable 5021 does not deviate, thereby ensuring that the ampoule bottle does not leave the area where the respective bottle rotation stabilization group 502 is located when the ampoule bottle is driven to rotate by the friction mechanism 9; therefore, the inner side of the feeding arc plate 4012 is flush with the outer track of the ampoule bottle rotation on the circular loading platform 507.

[0094] like Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 13 The turntable mechanism 5 shown includes: a working base surface 501, a rotating indexing plate 503, a reducer 505, a turntable drive motor 506, a circular stage 507 and a bottle rotation stabilization group 502, wherein the working base surface 501 is installed above the frame through a bracket, the circular stage 507 and the output shaft of the reducer 505 are connected to the rotating part of the rotating indexing plate 503 from the upper and lower directions, the base of the rotating indexing plate 503 is fixed to the working base surface 501, and the bottle rotation stabilization group 502 is evenly installed on the outer periphery of the upper end surface of the circular stage 507; the input shaft of the reducer 505 is connected to the output shaft of the turntable drive motor 506; the turntable drive motor 506 is installed below the working base surface 501 through a bracket.

The upper and lower sections of the bottle side bearing support column 5023 are each installed with a bottle side support bearing 5022, and the outer periphery of the bottle side support bearing 5022 is tangent to the bottle body of the ampoule bottle. The ampoule bottle is placed above the small turntable 5021, and the bottle side support bearing 5022 ensures that the ampoule bottle does not tip over; the limiting column group composed of the small turntable 5021 and the bottle side support bearing 5022 allows the ampoule bottle to rotate smoothly.

[0100] The upper universal joint 704 and the lower universal joint 707 for transmitting torque both play the role of self-correction of pump body eccentricity; the pump core axial guide assembly 708 is used to ensure the accuracy of the injection stroke of the injection pump 701;

[0101] The injection pump 701 with intermittent injection function is as follows Figure 12 As shown, it includes: an injection pump core 7011, an injection pump barrel 7012, a pump filling liquid inlet 7014 and a pump filling liquid outlet 7015.

The pump filling liquid inlet 7014 and the pump filling liquid outlet 7015 are provided on the upper part of the side wall of the injection pump barrel 7012. The middle and lower part of the injection pump barrel 7012 is provided with a liquid containing portion (not shown in the figure). As the injection pump core 7011 moves axially, the groove (not shown in the figure) on the injection pump core 7011 periodically connects the liquid containing portion with the pump filling liquid inlet 7014 or the pump filling liquid outlet 7015, thereby pressurizing (injecting) and releasing (pumping out) the liquid in the liquid containing portion.

[0102] like Figure 1 and Figure 9 As shown, the nozzle support frame 712 is installed on the profile 101 through the lifting device 714, and the injection nozzle 711 is installed below the nozzle support frame 712 through the nozzle mounting seat 713; the injection nozzle 711 is facing the small turntable 5021 (work station) below, and the liquid inlet of the injection nozzle 711 is connected to the pump filling liquid outlet 7015 of the injection pump 701 through a pipeline.

[0103] In this embodiment, the material of the structure of the pumping mechanism frame 702 is aluminum profile;

[0104] In this embodiment, the screw in the linear screw guide rail group 7081 is rotatably connected to the screw guide rail mounting frame 7082, the guide rail in the installed linear screw guide rail group 7081 is fixedly connected to the screw guide rail mounting frame 7082, the movable platform in the installed linear screw guide rail group 7081 is connected to the screw through a thread, and the movable platform is slidably connected to the guide rail.

[0105] like Figure 1 、 Figure 9 and Figure 10 The flame system 8 shown includes: a flame system base 801, a rotatable support body 802, a first flame nozzle 803, a second flame nozzle 804, a lifting cylinder 805 and a nozzle clamp 806, wherein the flame system base 801 is fixed on the working base 501 by a bracket, and the flame system base 801 is provided with a sliding groove 8011 and a cylinder mounting groove 8012; the lower end of the rotatable support body 802 is fixed in the sliding groove 8011 provided on the flame system base 801, and the upper end of the rotatable support body 802 is clamped and fixed with the first flame nozzle 803, which mainly serves to preheat and prevent the ampoule from breaking; the lifting cylinder 805 is installed on the cylinder mounting groove 8012 by a bracket, and the second flame nozzle 804 is fixed to the moving part of the lifting cylinder 805 by the nozzle clamp 806; the second flame nozzle 804 provides a high-intensity flame to heat the ampoule so that it can quickly reach a softened state of the glass.

[0106] like Figure 10 As shown, the mixer input ends of the first flame nozzle 803 and the second flame nozzle 804 are both connected to the mixing chamber through flow valves, and the two gas input ends of the mixing chamber are connected to the oxygen source or the fuel gas source in sequence through their own mass flow meters, solenoid valves and pressure valves; the multi-stage pressure reduction and multi-cavity mixing method make the output mixed gas smooth and uniform, thereby ensuring the stable output of the flame.

[0107] In this embodiment, an igniter fixing seat 807 is installed below the flame nozzle 803, which is mainly used to fix the pulse igniter to ignite the gas to achieve a heating effect. A manual ignition device can also be used for ignition to replace the igniter fixing seat 807.

[0108] like Figure 9 and Figure 13 The friction rotating mechanism 9 shown includes: a friction wheel 901, a friction wheel coupling 902, a self-aligning structure 903 and a friction mechanism power source 904, wherein the self-aligning structure 903 and the friction mechanism power source 904 are respectively fixed to the upper and lower ends of the working base surface 501, and the power output of the friction mechanism power source 904 is connected to the friction wheel 901 through a gear set, a self-aligning structure 903, and a friction wheel coupling 902, so that the friction wheel 901 rotates and drives the ampoule bottle on the corresponding workstation to rotate through the friction side wall.

[0109] In this embodiment, the friction wheel 901 is made of aluminum, and its surface is sandblasted to increase friction.

[0110] like Figure 1 、 Figure 9 and Figure 14 The bottle collecting mechanism 11 shown includes a table 111, a table frame 112, a guardrail 113, and a bottle hook plate assembly 114. The table 111 is fixed to the work base 501 via the table frame 112. The guardrail 113 is installed on the periphery of the table 111 to prevent ampoules from falling. One end of the bottle hook plate assembly 114 is set on the table 111, and the other end of the bottle hook plate assembly 114 extends to the work station, thereby removing the ampoule from the circular loading platform 507 and guiding the ampoule into and placing it on the table 111.

[0111] In this embodiment, the guardrail 113 on one side is replaced by a detachable baffle 115. After the baffle in the detachable baffle 115 is removed, the ampoule bottles can be filled and collected at the same time, or a bottle collection device with a larger capacity can be connected.

[0112] like Figure 1 The display system 3 shown is mounted on the main frame 1 via a support column. In this embodiment, the display system 3 is a multifunctional touch screen. The multifunctional touch screen is connected to the PLC as an input. The control system is installed in the PLC. The PLC is connected to the conveying mechanism motor 205, the auger motor 401, the turntable drive motor 506, the wire drawing power mechanism 601, the lifting mechanism, the gripper drive cylinder, the swing arm mechanism 604, the injection pump core steering motor 706, the hydraulic lifting device 714, the pump core axial motor 7083, the lifting cylinder 805, the friction mechanism power source 904, the flow valve, the mass flow meter, the solenoid valve, and the pressure valve through relays to control all devices of the equipment.

[0113] The PLC includes a control system for fully automatic single-channel, dual-needle sealing equipment. Single-channel bottle feeding refers to the auger mechanism 4 feeding only one bottle to the rotation stabilization group 502 per rotation. Dual-needle injection involves two sets of first flame nozzle 803, second flame nozzle 804, gripper 605, and injection nozzle 711. Therefore, each two sets of workstation information for the auger mechanism 4 and turntable mechanism 5 correspond to one set of workstation information for the wire drawing mechanism 6, pumping mechanism 7, and flame system 8. To prevent damage to these components during operation, the following requirements must be met: 1. After the turntable stops and completes its positioning, the auger rotates and completes its rotation before the next turntable rotation. 2. After the turntable is positioned, the injection mechanism performs positioning, injection, and reset operations, and completes its liquid aspiration operation before the next turntable positioning, waiting for the turntable to position. Furthermore, the heating portion of the flame system lowers the flame nozzle after the turntable is positioned and raises it before the next turntable positioning. 3. The wire drawing mechanism performs wire drawing after the flame descends and is completed before the turntable starts at an odd position; then, before the next flame descends, the wire drawing mechanism completes the parabolic action and the positioning action in sequence.

[0114] like Figure 2 The control system shown controls the joint operation of the components through the previously set timing, and monitors the feedback through the relay, and stops the equipment if it is different from the set opening time;

[0115] The control system includes: a timer module, a turntable rotation module, an auger rotation module, a filling needle control module, a wire drawing mechanism moving module and a flame mechanism lifting module, wherein the timer module is respectively connected to the turntable rotation module, the auger rotation module, the filling needle control module, the wire drawing mechanism moving module and the flame mechanism lifting module; the turntable rotation module is connected to the turntable drive motor 506 through a turntable relay; the auger rotation module is connected to the auger motor 401 through an auger relay; the filling needle control module is connected to the hydraulic lifting device 714 through a nozzle lifting relay; the flame mechanism lifting module is connected to the lifting cylinder 805 through a flame lifting relay; the wire drawing mechanism moving module is connected to the gripper drive cylinder relay through a gripper drive cylinder relay, the wire drawing mechanism moving module is connected to the lifting mechanism through a lifting mechanism relay, and the wire drawing mechanism moving module is connected to the wire drawing power mechanism 601 through a wire drawing power mechanism relay.

[0116] During the initialization, the execution time of each module is sorted and set according to the working sequence and required working time within the cycle;

[0117] During operation, each module sends a signal to the corresponding relay to perform various actions in sequence. Each relay returns an electrical signal after execution. The timer module verifies the electrical signal returned by each relay. If it is in place or returns an abnormality, the entire process is stopped and displayed on the multi-function touch screen;

[0118] The timer module is connected to the turntable sensor, the nozzle bottom-down sensor, and the gripper top-up sensor, and receives signals from these sensors. The timer module has an independent time axis to ensure the safety of key components. The time axis includes: even stations and odd stations, where the duration of the odd station is the set value.

[0119] After the turntable sensor detects that the turntable has stopped, it sends a turntable stop signal to the timer module; after receiving the turntable stop signal, the timer module confirms the turntable position, and after confirming that the turntable is in place, it checks with the work position of the timer module; when the pointer in the timer module is in the even position, the timer module sends an even position confirmation signal B to the auger rotation module, the filling needle control module and the flame mechanism lifting module; when the pointer in the timer module is in the odd position, the timer module sends an odd position confirmation signal C to the auger rotation module;

[0120] After the nozzle bottom drop sensor detects that the lifting cylinder has dropped, it sends a wire drawing start signal to the timer module. The timer module then sends a wire drawing start signal D to the wire drawing mechanism moving module. At this time, the wire drawing mechanism moving module should be in the waiting process after completing the gripper positioning action. After receiving the wire drawing start signal D, the wire drawing mechanism moving module starts to execute the wire drawing action.

[0121] After the gripper lift sensor detects that the gripper drive cylinder has lifted, it sends a wire drawing completion signal A to the timer module. After receiving the wire drawing completion signal A, the timer module jumps to the odd station; after the odd station reaches the set value, it automatically jumps to the even station.

[0122] A drive cycle module for turntable rotation includes four actions: even position start, even position stop, odd position start and odd position stop. When the even position starts and the odd position starts, the turntable rotation module sends a turntable rotation signal to the turntable relay to drive the turntable drive motor 506 to rotate. When the odd position stops and the even position stops, the turntable rotation module sends a turntable stop signal to the turntable relay to stop the rotation of the turntable drive motor 506.

[0123] A driving cycle of auger rotation includes two actions: auger rotation and auger stop. During the waiting process, the auger rotation module performs the auger rotation action after receiving the even-position confirmation signal B or the odd-position confirmation signal C sent by the timer module, and performs the auger stop action after the auger rotates one circle. After the auger relay returns the auger stop signal, the auger rotation module enters the waiting process; the auger rotation action is: the auger rotation module sends the auger rotation signal to the auger relay to drive the auger motor 401 to rotate; the auger stop action is: the auger rotation module sends the auger stop signal to the auger relay to confirm that the auger motor 401 stops; if the even-position confirmation signal B or the odd-position confirmation signal C is received during the non-waiting process, the entire device stops and an error is reported.

[0124] A driving cycle of the filling needle control includes four actions: nozzle setting, nozzle injection, nozzle reset and liquid aspiration. During the waiting process, the filling needle control module performs the nozzle setting action after receiving the even position confirmation signal B sent by the timer module. After the nozzle setting action is completed, the nozzle injection action is performed. After the nozzle injection action is completed, the liquid aspiration action is performed. After the liquid aspiration action is completed, the waiting process begins. The nozzle setting action is as follows: the filling needle control module sends a nozzle setting signal to the nozzle lifting relay to drive the hydraulic lifting device 714 to make the nozzle support frame 712 descend and extend the injection nozzle 711 into the ampoule bottle below. The nozzle injection operation is as follows: the filling needle control module sends a nozzle injection signal to the pump core axial motor 7083, which pushes the syringe pump 701 to release pressure, thereby allowing the nozzle to discharge liquid. The nozzle reset operation is as follows: the filling needle control module sends a nozzle reset signal to the nozzle lift relay, driving the hydraulic lift device 714 to raise the nozzle support frame 712 and remove the syringe nozzle 711 from the ampoule body. The liquid aspiration operation is as follows: the pump core axial motor 7083 pulls out the syringe pump 701 to increase pressure, allowing the syringe pump 701 to complete the liquid aspiration operation. During the aspiration operation, the nozzle remains stationary. If an even position confirmation signal B is received during the non-waiting process, the entire device stops and an error is reported.

[0125] A driving cycle of the flame mechanism lifting includes two actions: flame descending and flame ascending. During the waiting process, the flame mechanism lifting module performs a flame descending action after receiving the even position confirmation signal B sent by the timer module, and performs a flame ascending action after the flame descending action is completed. After the flame ascending action is completed, it enters the waiting process; the flame descending action is: the flame mechanism lifting module sends a flame descending signal to the flame lifting relay to push the lifting cylinder 805 down so that the second flame nozzle 804 descends; the nozzle descending sensor monitors the position of the nozzle fixture 806 (or the second flame nozzle 804); the flame ascending action is: the flame mechanism lifting module sends a flame ascending signal to the flame lifting relay to push the lifting cylinder 805 up so that the second flame nozzle 804 ascends; if the even position confirmation signal B is received in the non-waiting process, the entire device is stopped and an error is reported.

[0126] A driving cycle of the wire drawing mechanism movement includes three actions: wire drawing (gripper clamps and rises), gripper throwing and gripper positioning; during the waiting process, the wire drawing mechanism moving module receives the wire drawing start signal D sent by the timer module, and then performs the wire drawing action. After the wire drawing action is completed, the gripper throwing action is performed. After the gripper throwing action is completed, the gripper positioning action is performed. After the gripper positioning action is completed, the waiting process is entered; the wire drawing action is: the wire drawing mechanism moving module sends a gripper clamping signal to the gripper drive cylinder relay to reduce the distance between the grippers 605 to clamp the bottle mouth of the ampoule, and then sends a wire drawing signal to the elevator The gripper's positioning relay changes the height of gripper 605, lifting the gripped ampoule's mouth. The gripper's throwing motion involves the wire drawing mechanism's movement module sending a gripper throwing signal to the wire drawing power mechanism relay, causing the wire drawing power mechanism 601 to drive shaft 603 to rotate. This signal then sends a gripper throwing signal to the gripper drive cylinder relay, increasing the distance between grippers 605 and allowing the ampoule's mouth to fall into the waste recycling device 109 below. The gripper's positioning motion involves the wire drawing mechanism's movement module sending a gripper setting signal to the wire drawing power mechanism relay, driving shaft 603 to rotate and returning gripper 605 to above the ampoule's resting position. If a wire drawing start signal D is received during a non-waiting period, the entire device stops and an error is reported.

[0127] Since the wire drawing action requires contact with the ampoule bottle and requires coordination between multiple modules, there are relatively strict execution requirements. In this embodiment, the time proportion of the even station is greater than that of the odd station, which reduces the time of the odd station, ensures operation safety, and improves the overall operation speed.

[0130] The turntable mechanism 5 first drives the turntable drive motor 506 to rotate (even position start), and then stops after rotating through the angle of one station (even position stop);

[0131] Step 2: The turntable mechanism performs even position positioning:

[0132] After receiving the turntable stop signal, the timer module confirms the turntable position and checks it with the workstation where the timer module is located after confirming that the turntable is in place;

[0133] At this time, the pointer in the timer module is in the even position, and the timer module sends an even position confirmation signal B to the auger rotation module, the filling needle control module and the flame mechanism lifting module;

[0134] Step 3: The even position confirmation signal B simultaneously wakes up the filling needle control module, the flame mechanism lifting module and the wire drawing mechanism moving module in the waiting process:

[0135] During the waiting process, the filling needle control module performs the nozzle setting action after receiving the even position confirmation signal B sent by the timer module. After the nozzle setting action is completed, the nozzle liquid injection action is performed. After the nozzle liquid injection action is completed, the liquid suction action is performed. After the liquid suction action is completed, the waiting process is entered.

[0136] During the waiting process, the flame mechanism lifting module performs a flame lowering action after receiving the even position confirmation signal B sent by the timer module, and performs a flame raising action after the flame lowering action is completed. After the flame raising action is completed, the waiting process is entered;

[0137] During the waiting process, the wire drawing mechanism moving module receives the wire drawing start signal D sent by the timer module and performs the wire drawing action. After the wire drawing action is completed, the gripper throws the object. After the gripper throws the object, the gripper sets the object. After the gripper sets the object, the waiting process begins.

[0138] Step 4: The wire drawing completion signal A causes the pointer in the timer module to jump to the odd position:

[0139] After the gripper lift sensor detects that the gripper drive cylinder has lifted, it sends a wire drawing completion signal A to the timer module. After receiving the wire drawing completion signal A, the timer module jumps to the odd work position.

[0140] Step 5: The turntable mechanism starts and stops at odd positions:

[0141] The turntable mechanism 5 drives the turntable drive motor 506 to rotate according to the set time point (odd position start), and stops after rotating through the angle of one station (odd position stop);

[0142] Step 6: The turntable mechanism performs odd-position positioning:

[0143] Then the timer module confirms the position of the turntable after receiving the turntable stop signal, and after confirming that the turntable is in place, it checks with the workstation where the timer module is located;

[0144] At this time, the pointer in the timer module is in the odd position, and the timer module sends an odd position confirmation signal C to the auger rotation module. After the odd position reaches the set value (set value time), it automatically jumps to the even position.
