Description
Technical Field
The invention relates to the field of pharmaceutical equipment. Specifically, the invention relates to a nitrogen protection system of a filling and sealing machine.
Background
The filling and sealing machine is widely applied to the food and pharmaceutical packaging machinery industry, and the main procedures of the filling and sealing machine are that bottle feeding, front nitrogen filling, liquid medicine filling, back nitrogen filling, wire drawing and sealing are sequentially carried out along a bottle conveying track, and bottle discharging is carried out. As most of products have technological characteristic requirements and must meet the residual oxygen index of 2-3% (even lower), the front and back nitrogen filling procedures occupy an extremely important position in the whole filling link.
Referring to fig. 1, taking the conventional AGF12 filling and sealing machine as an example, the PLC controls the operation of the bottle feeding device and the air charging device respectively in two paths. When the nitrogen charging is normal, the electromagnetic valve enables the gas supply channel to be in a gas circuit state, nitrogen is supplied to the ampoule bottle through the electromagnetic valve, the rotor flow meter and the aerator, and an intermediate relay in the equipment electric control cabinet flickers at the moment and is used for indicating the normal state of the nitrogen charging. When the nitrogen charging system breaks down, the electromagnetic valve makes the gas supply channel in a closed state, and the intermediate relay stops flashing. And after observing that the relay stops flashing, an operator manually operates the PLC system to stop the operation of the bottle feeding device. However, the current flowing through the contact point at the output end of the intermediate relay is large, the intermediate relay is easy to damage, and because the intermediate relay is arranged inside the equipment electric control cabinet, an operator can not monitor the change of the nitrogen charging system in time, and because the PLC can not stop working automatically, the bottle feeding process of the bottle feeding device is still continuously carried out. Because no nitrogen gas is filled, the filled liquid medicine loses the protection of the nitrogen gas, and the residual oxygen amount is seriously unqualified, so that a large batch of products are directly scrapped.
Therefore, the current filling and sealing machine and the filling and sealing nitrogen charging system still have room for improvement.
Disclosure of Invention
The present invention aims to solve, at least to some extent, the technical problems of the prior art. Therefore, the invention provides an improved nitrogen protection system of a filling and sealing machine and a method for filling and sealing the filling and sealing machine by using the improved nitrogen protection system, which can ensure that a bottle feeding device can automatically stop feeding bottles when a nitrogen supply device fails and the nitrogen filling is stopped, and avoid the rejection of large batches of products due to the fact that an operator cannot find the products in time.
In the process of solving the problems in the prior art, the inventor considers directly solving the problems of instability and easy damage of the relay, and tries 2 sets of treatment schemes as follows:
the first scheme is as follows: 2 pneumatic diaphragm valves are added between the electromagnetic valve and the rotameter, the intermediate relay controls the opening of the electromagnetic valve, and the electromagnetic valve controls the pneumatic diaphragm valves to control the on-off of the nitrogen. The current that flows through intermediate relay can reduce in this scheme, can prolong intermediate relay's life, but pneumatic diaphragm valve also can appear damaging, trouble, still can produce finally because artificial observation is untimely, and the product that the shut down is untimely leads to is scrapped a large number of products and is scrapped
Scheme II: and changing a control circuit, and changing the input power supply of the intermediate relay from alternating current to direct current, thereby replacing the intermediate relay with a solid-state relay with stable and mature performance. However, solid-state relays are only relatively stable and still cannot guarantee that no failure has occurred. Moreover, changing to a solid state relay requires changing the process parameters of the entire system, greatly increasing the difficulty and cost of providing the retrofit. The inventors believe that the modifications to the intermediate relay alone do not always solve the persistent problems of the prior art.

The invention provides a nitrogen protection system of a filling and sealing machine and a method for filling and sealing the filling and sealing machine by using the nitrogen protection system of the filling and sealing machine, which are respectively described in detail below.
Nitrogen protection system of filling and sealing machine
In one aspect of the invention, the invention provides a nitrogen protection system of a filling and sealing machine. According to an embodiment of the invention, referring to fig. 2, the system comprises: the automatic bottle feeding device comprises a controller 100, an intermediate relay 200, a gas supply device 300, an electromagnetic valve 400, a first gas path P1 and a second gas path P2, wherein an inflator 500 is arranged in the first gas path P1, and a pressure switch 600, the controller 100 and a bottle feeding device 700 which are connected are arranged in the second gas path P2. Each of the components will be described in detail below.
According to an embodiment of the present invention, the intermediate relay 200 is connected to the controller 100, and the solenoid valves are connected to the intermediate relay 200 and the gas supply device 300, respectively. Therefore, the controller can control the electromagnetic valve to be opened or closed by controlling the intermediate relay. When the electromagnetic valve is opened, the gas supplied by the gas supply device can flow through the electromagnetic valve and enter the first gas path and the second gas path; when the electromagnetic valve is closed, the gas supplied by the gas supply device cannot pass through the electromagnetic valve.
According to an embodiment of the present invention, the first and second air passages P1 and P2 are connected in parallel with the solenoid valve 400. Thus, the gas supplied by the gas supply device can be introduced into the first gas path and the second gas path, respectively.
According to the embodiment of the invention, the pressure switch 600 is connected with the solenoid valve 400, the pressure switch 600 is suitable for feeding back a signal to the controller according to the pressure state, and when the feedback signal feeds back that the system is normal, the controller 100 is used for controlling the bottle feeding device 700 to work normally; when the feedback signal feedbacks a system abnormality, the controller 100 is used for controlling the bottle feeding device 700 to stop working. The air pressure therethrough can be detected by a pressure switch. If the preset pressure condition is met, the nitrogen supply of the nitrogen filling gas circuit is proved to be normal, at the moment, the pressure switch feeds back a first signal to a PLC (programmable logic controller) control system, and the PLC control system controls the bottle feeding device to feed bottles. If the preset pressure condition is not met, the nitrogen supply of the nitrogen filling gas circuit is proved to be abnormal, at the moment, the pressure switch feeds back a second signal to the PLC control system, and the PLC control system controls the bottle feeding device to stop feeding bottles. By utilizing the system, the bottle feeding device can automatically stop feeding bottles when the nitrogen supply device fails and stops filling nitrogen, so that the waste of products caused by the fact that an operator cannot find the bottles in time is avoided.
According to the embodiment of the present invention, when the air pressure flowing through the pressure switch 600 is less than the threshold value, the feedback signal feeds back that the system is abnormal; when the air pressure flowing through the pressure switch 600 is not less than the threshold value, the feedback signal feeds back that the system is normal. Specifically, the threshold value is 0.1-1.0 MPa. Therefore, when the pressure detected by the pressure switch is lower than the set threshold value, the failure of gas supply is indicated, and the supply of nitrogen gas is stopped or the amount of nitrogen gas is too small, and at the moment, the bottle feeding is stopped. If the pressure detected by the pressure switch is greater than or equal to the set threshold value, the gas supply is normal, and the bottle can be filled with nitrogen. When the pressure detected by the pressure switch is 0.1Mp, the corresponding nitrogen amount is 0.1 Mp; when the pressure detected by the pressure switch is 1.0Mp, the corresponding amount of nitrogen is 1.0 Mp. It should be noted that the threshold value is set to any value within the range of 0.1 to 1.0Mpa, and may be set arbitrarily according to the air supply amount of the nitrogen supply device of the filling and sealing machine, and may be set within the range of 0.1 to 1.0 Mpa.
According to an embodiment of the present invention, a pressure adjusting nut is provided on the pressure switch 600. The pressure switch adopted by the invention only outputs two signals, namely on and off, and the signals transmitted to the plc control system are 1 and 0, wherein the on corresponds to 1, and the off corresponds to 0. The invention selects a normally closed pressure switch, which is 1 in a normal state (a conducting state). If the minimum flow required for production is the meter display scale 30, the rotor can be positioned at 30 by the rotor meter knob and then be the on and off switching point by adjusting the adjusting screw on the pressure switch. I.e., from 1 to 0, 0 when greater than 30, and 1 when less than 30. In production, nitrogen is not supplied all the time due to production requirements, but is supplied once in a cycle period. The front end is provided with an electromagnetic valve for controlling the on-off of the nitrogen, and the nitrogen is set by the original factory and is not adjusted. Due to the nitrogen on and off, the pressure switch will switch between 1 and 0 during the time period. The signal for plc is the pulse signal of 0 and 1, writes into the logical relation of plc procedure promptly, when 1 is greater than 5 seconds in the production, stops the auger, and the screen shows alarm information. Here the 5 second time can be modified in plc, as required by the production. Therefore, the lowest threshold value of the nitrogen is determined by adjusting the pressure adjusting nut, when the pressure of the entering nitrogen is lower than the threshold value, the pressure switch transmits a signal to the PLC, and the PLC controls the bottle feeding device to stop running.
According to the embodiment of the invention, when the nitrogen protection is not needed, the controller is used for controlling the bottle feeding device to work normally. Because the encapsulation of some medicines need not to fill nitrogen protection, consequently, through the further preset program in PLC control system, operating personnel can also switch over from filling nitrogen protection mode to not having nitrogen protection mode program, promptly, no matter the signal of pressure switch feedback is the system normal or unusual, advance the bottle device and all normally advance the bottle. Therefore, the free switching between the nitrogen charging protection mode and the nitrogen-free protection mode can be realized according to the actual production requirements, and the application range of the system is expanded.
According to an embodiment of the invention, the inflator is a nitrogen needle. Thereby, the nitrogen gas is accurately filled into the bottle body.
According to an embodiment of the present invention, the first air path further includes: and the rotameter is respectively connected with the electromagnetic valve and the aerator. The rotor flow meter is provided with a rotor, when the flow of fluid is measured, the measured fluid flows in from the lower end of a conical pipe of the rotor flow meter, the flow of the fluid impacts the rotor and generates an acting force on the rotor, and when the flow is large enough, the generated acting force supports the rotor. The required flow is controlled by the adjusting knob of the rotameter and the scales.
According to an embodiment of the invention, the system further comprises: an operation panel connected to the controller 100. Therefore, when the pressure detected by the pressure switch is lower than the threshold value, the red light can be turned on the operation screen normally, and the warning words of 'please check nitrogen gas' are shown, so that the staff can check the nitrogen gas in time.
