Description

[0003] In practice, the packaging barrel is cleaned first, and then high-purity electronic grade H2O2 is filled. The cleaning quality of the manual cleaning of the packaging barrel requires the operator to be highly conscious and strictly standardized, such as consciously flushing water and consciously fully draining liquid. However, the actual manual cleaning quality is difficult to control, the water content and / or the residual H2O2 content before mixing are large, which affects the quality of high-purity electronic grade H2O2. In addition, when filling high-purity electronic grade H2O2 manually, the operator may come into contact with electronic grade hydrogen peroxide products, which may cause safety accidents or product quality problems.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 This utility model provides an automatic filling production line, including an automatic conveyor 100, an automatic drum washing machine 200, an automatic filling machine 300, and an automatic capping machine 400. The automatic conveyor 100 is sequentially arranged along the conveying direction as a first buffer transfer section 110, a drum washing transfer section 120, a second buffer transfer section 130, a filling transfer section 140, a third buffer transfer section 150, and a capping transfer section 160. The filling transfer section 140 includes an electronic scale 141 for weighing the actual weight of the packaging drums 600 on it. The automatic drum washing machine 200 and the automatic filling machine... Automatic conveyor 100, automatic drum washing machine 200, automatic filling machine 300, automatic lidding machine 400 are respectively located above the drum washing transfer section 120, the filling transfer section 140, and the lidding transfer section 160. The drum washing transfer section 120, the filling transfer section 140, and the lidding transfer section 160 are equipped with a first position detection switch, a second position detection switch, and a third position detection switch. Automatic conveyor 100, automatic drum washing machine 200, automatic filling machine 300, automatic lidding machine 400, and the first, second, and third position detection switches are all electrically connected to the central control unit.

[0036] In addition, the drum washing transfer section 120 and the first buffer transfer section 110 are used to pause because the first position detection switch detects the packaging drum 600 and the automatic drum washing machine 200 has not cleaned the drum, otherwise start. The automatic drum washing machine 200 is used to start a cleaning action including spraying and pumping when the first position detection switch newly detects the packaging drum 600.

[0037] The filling transfer section 140 and the second buffer transfer section 130 are used to pause when the second position detection switch detects the packaging barrel 600 and the automatic filling machine 300 has not filled the barrel, and otherwise start. The automatic filling machine 300 is used to start the filling action when the second position detection switch newly detects the packaging barrel 600.

[0038] The top cover transmission section 160 and the third buffer transmission section 150 are used to pause when the third position detection switch detects the packaging barrel 600 and the automatic capping machine 400 has not capped the barrel, otherwise they will start. The automatic capping machine 400 is used to start a capping action when the third position detection switch newly detects the packaging barrel 600.

[0039] It can be understood that the automatic conveyor 100 can be a belt type, which includes a conveying belt, a belt pulley for being wound by the conveying belt, and a conveying motor connected with the belt pulley, which can be a variable frequency motor, a servo motor, etc. The conveying motor is electrically connected with the central control machine through a frequency converter or a servo controller, and the electronic scale 141 is electrically connected with the central control machine.

[0040] The automatic conveyor 100 is divided into multiple sub-conveying sections, i.e., each sub-conveying section includes a separate conveying belt, a belt pulley and a conveying motor. The automatic conveyor 100 is electrically connected with the central control machine, i.e., each conveying motor is electrically connected with the central control machine, to realize automatic control of conveying, i.e., when the in-place detection switch is checked (i.e., the signal sending circuit of the in-place detection switch is turned on / cut off, and the central control machine receives the corresponding high level / low level), the central control machine sends corresponding signals (essentially one or more electric waves / level change waves) such as common PWM signals to the frequency converter / servo controller of the conveying motor through self-owned or additionally set motor driving circuit (such as amplification circuit, AD conversion circuit, etc.).

[0041] Referring to Figure 1 , Figure 2 , the automatic conveyor 100 can also be a roller type conveying, multiple conveying rollers are arranged along the conveying direction in each sub-conveying section, the conveying rollers are drivingly connected with the conveying motor, and each conveying motor is electrically connected with the central control machine.

[0042] The conveying structure in combination with the electronic scale 141 is a conventional design. Referring to Figure 1 , specifically, the filling sub-conveying section 140 includes a base, an electronic scale 141 arranged on the base, and a conveying main body serving as a tray of the electronic scale 141; the conveying main body can be a conveying belt and its mounting rack, a motor, or a plurality of conveying rollers and their mounting racks, a motor.

[0043] The controlled elements of the automatic cap applying machine 400 include a cylinder or a motor for releasing the cap stack, a cylinder or a motor for controlling the rotation handle to move away from or close to the barrel opening of the packaging barrel 600, and a cap twisting motor for controlling the rotation of the rotation handle. The cylinder can be an electric cylinder or a pneumatic cylinder, and the cap twisting motor can be finely controlled, such as a variable frequency motor or a servo motor, and a frequency converter or a servo controller is correspondingly arranged. The other cylinders and motors of the automatic cap applying machine 400 can only control start and stop, and the central control machine can only be electrically connected with these controlled elements through an NPN transistor or a MOSFET field effect transistor.

[0044] Referring to Figure 1 , Figure 2The same kind has an automatic barrel washing machine for flushing the packaging barrel 600, and a pump for pumping and draining the flushing liquid, so the controlled elements of the automatic barrel washing machine 200 include a water pump, a cylinder or a motor for driving the flushing rod 230 and the pumping and draining rod 240 in and out of the packaging barrel 600, and the controlled physical quantity of the controlled elements can only be start-stop, and the in-place point can be relatively rough. The same kind also has an automatic filling controlled element, which is a water pump, and a cylinder or a motor for controlling the filling nozzle 310 to enter and exit the packaging barrel 600.

[0045] The industrial central control machine commonly used in industry mainly includes a central processing unit, peripheral key switch knob switch circuit, detection switch circuit, display circuit, LED indicator light circuit, buzzer circuit, and motor drive circuit. The processor can be an Intel series processor, an AMD series processor, an embedded processor, an ARM architecture processor, etc., which integrates a memory, an oscillation circuit, a timer, a counter, etc. The indicator light circuit, the buzzer circuit, and the switch circuit only need to control start-stop / turn-on and turn-off, and they are generally connected to the central processing unit through an NPN transistor or a MOSFET. Some displays are integrated with touch buttons.

[0046] Referring to Figure 1 The operation process of the utility model can have a barrel loading process, a barrel washing process, a filling process, and a cover loading process.

[0047] The barrel loading process, the barrel loading mechanical arm, the barrel discharging inclined path, the barrel loading sub-transmission section, and / or human beings, etc. transmit the packaging barrel 600 to the first buffer sub-transmission section 110;

[0048] The barrel washing process, the first buffer sub-transmission section 110 transports the packaging barrel 600 to the barrel washing sub-transmission section 120, when the first in-place detection switch of the barrel washing sub-transmission section 120 detects a new packaging barrel 600, the central control machine is informed and instructed to pause the first buffer sub-transmission section 110 and the barrel washing sub-transmission section 120, the central control machine instructs the automatic barrel washing machine 200 to start, the flushing rod 230 and the pumping and draining rod 240 intrude into the packaging barrel 600 of the barrel washing sub-transmission section 120, in the central control machine, the detection times of the first in-place detection switch are cleared (i.e. reset, for subsequent new detection), the water pump connected to the flushing rod 230 is started, and the flushing rod 230 sprays clean water or reusable liquid into the packaging barrel 600 to flush and / or soak the packaging barrel 600, the packaging barrel 600 is soaked for X minutes, such as 0.1 minutes, the water pump connected to the pumping and draining rod 240 is started to drain the flushing and soaking liquid in the packaging barrel 600, the flushing and pumping and draining are executed once or more times, after the automatic barrel washing machine 200 completes the cleaning of the packaging barrel 600, the barrel washing sub-transmission section 120 and the first buffer sub-transmission section 110 are started, the barrel washing sub-transmission section 120 replenishes the packaging barrel 600 to the second buffer sub-transmission section 130, and the first buffer sub-transmission section 110 replenishes the packaging barrel 600 to the barrel washing sub-transmission section 120.

[0049] Specifically, it can be, such as, flushing and pumping twice, once with the complex liquid flushing immersion, once with clean water flushing immersion, better to reduce the amount of residual pollutants; water derived from flushing immersion liquid, can be used for complex liquid, pumping to and fro complex liquid tank. The flow rate of the filling pump, the flow rate of the flushing pump, the flow rate of the pumping pump, the barrel washing process (two flushing and pumping time) is as close as possible to the length of the filling process.

[0050] It can be understood that the packaging barrel 600 is generally made of plastic, rubber, etc., which is relatively light, and the packaging barrel 600 is easily stopped by friction. The conveying belt is relatively rough, and the conveying roller can also be a rubber roller to further ensure the friction. Further, the automatic conveyor is provided with a stop structure 170 as described below.

[0051] Wherein, when the first buffer sub-transmission section 110 is paused, the barrel discharge chute and / or the barrel loading sub-transmission section can only squeeze one packaging barrel 600 into the idle input end of the paused first buffer sub-transmission section 110. When the first buffer sub-transmission section 110 is squeezed into the packaging barrel 600, the overall frictional resistance of the first buffer sub-transmission section 110 makes the barrel discharge chute and the barrel loading sub-transmission section slip. Preferably, the barrel discharge chute and the barrel loading sub-transmission section use roller transmission, and the transmission roller has a metal outer surface, i.e. even the entire transmission roller is metal. When the first buffer sub-transmission section 110 is paused, the barrel loading sub-transmission section mainly slips.

[0052] The filling process, the second buffer sub-transmission section 130 transports the packaging barrel 600 to the filling sub-transmission section 140. When the second-in-place detection switch of the filling sub-transmission section 140 detects a new packaging barrel 600, the central control machine is informed and instructed to pause the second buffer sub-transmission section 130 and the filling sub-transmission section 140. Then, in the central control machine, the detection number of the second-in-place detection switch is cleared (i.e. reset, convenient for subsequent new detection), the central control machine instructs the water pump connected to the filling nozzle 310 to start, and the filling nozzle 310 works for X minutes, such as 0.6 minutes, so that the packaging barrel 600 obtains the corresponding filling amount, and the automatic filling machine 300 completes the filling of the current packaging barrel 600. After that, the filling sub-transmission section 140 and the second buffer sub-transmission section 130 are started, the filling sub-transmission section 140 supplies the packaging barrel 600 to the third buffer sub-transmission section 150, and the second buffer sub-transmission section 130 supplies the packaging barrel 600 to the filling sub-transmission section 140.

[0053] Wherein, the filling nozzle 310 can be spaced, downwardly spraying hydrogen peroxide into the packaging barrel 600. The automatic filling machine 300 can also be provided with a second lifting mechanism 320, and the central control machine is also used to instruct the cylinder or motor of the second lifting mechanism 320 to start, and the second lifting mechanism 320 is suitable for driving the filling nozzle 310 to ascend and descend to enter and exit the packaging barrel 600, i.e. after the filling nozzle 310 is inserted into the packaging barrel 600, hydrogen peroxide is filled again to reduce the splashing caused by filling, and also to improve the filling flow rate.

[0054] In the capping process, the third buffer transfer section 150 conveys the packaging drum 600 to the capping transfer section 160. When the third arrival detection switch of the capping transfer section 160 detects a new packaging drum 600, the central control unit is notified and instructs the third buffer transfer section 150 and the capping transfer section 160 to pause. Subsequently, the detection count of the third arrival detection switch in the central control unit is reset to zero (i.e., reset to facilitate subsequent new detections). The central control unit then instructs the automatic capping machine 400 to start. Figure 1 When the cylinder or motor of the capping machine is activated, the cap release plate is released and the rear stop plate stops, releasing the bottom single cap. This cap falls freely to the opening of the packaging drum 600. The handle is shifted and raised to fit the cap onto the cap. The handle is rotated to drive the cap to rotate relative to the opening of the packaging drum 600, tightening the cap (in essence, the cap and the handle are in a snap-fit ​​connection, rotating with the handle while moving downward relative to the handle). The handle rotates for Y seconds, such as 1.5 seconds, which means the cap rotates Z times, tightening the cap. After the automatic capping machine 400 completes the capping of the current packaging drum 600, the capping transfer section 160 and the third buffer transfer section 150 are started. The capping transfer section 160 outputs packaging drums 600 to facilitate subsequent labeling, coding, and / or stacking, etc. The third buffer transfer section 150 replenishes packaging drums 600 to the capping transfer section 160.

[0055] The handle can be connected to the cover motor via a torsion spring. For example, the cover motor rotates Z+0.5 turns to ensure that the cover and handle rotate Z turns. The torsion spring allows the handle and cover to stop rotating relative to the cover motor after tightening. Even better, the handle can be connected to the cover motor via a torque sensor. When the torque reaches value A, tightening the cover slows down; when the torque reaches value B, tightening the cover stops.

[0056] Compared with existing technologies, the beneficial effects of this application include: reducing manual intervention, ensuring cleaning and filling quality, reducing the labor intensity of operators, reducing the frequency of operators' contact with products, ensuring safety and product quality level, and improving production efficiency.

[0057] To ensure that the packaging barrel 600 stops accurately at the washing transfer section 120, the filling transfer section 140, and the cap transfer section 160, so that the extraction rod 240, the filling nozzle 310, and the handle can accurately enter and exit the opening of the packaging barrel 600, in some embodiments of this utility model, the automatic conveyor 100 is provided with two side stops, which form a limiting transfer channel between the two side stops to prevent the packaging barrel 600 from shifting left or right during transfer. (Refer to...) Figure 1The automatic conveyor 100 is equipped with multiple stop structures 170. The packaging barrels 600 in the washing barrel transfer section 120, the filling transfer section 140 and the top cover transfer section 160 are blocked or released by the corresponding stop structures 170, so that the packaging barrels 600 are paused or allowed to be transferred. The stop structure 170 includes a stop plate 171 and a stop cylinder 172 that drives the stop plate 171 to enter and exit the limit transfer channel.

[0058] It is understandable that the automatic transmission machine 100 is divided into multiple transmission segments, so the two side stops are also divided into multiple segments accordingly.

[0059] In some configurations, the stop plate 171 enters and exits the limit transmission channel from the side. (Refer to...) Figure 1 In some configurations, the stop plate 171 moves in and out of the limit transmission channel in the up and down direction.

[0060] Reference Figure 1 In some embodiments of this utility model, the stop plate 171 is adapted to move in and out of the gap between adjacent transfer sections, wherein the downstream transfer section serves as the backrest of the stop plate 171 when stopping the packaging barrel 600, utilizing favorable "natural" conditions to strengthen the stop, protect the stop plate 171, and effectively lock the inertial movement of the filled packaging barrel 600.

[0061] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the automatic drum washing machine 200 includes a first lifting mechanism 210, and also includes a flushing rod 230, a suction rod 240, and an air jet rod 250 for being lifted and lowered by the first lifting mechanism 210. Specifically, the packaging drum 600 may sequentially undergo reusable liquid rinsing and soaking, a first suction and discharge, clean water rinsing and soaking, a second suction and discharge, and air blowing and suction and discharge, so that the inside of the packaging drum 600 is dry and clean. During the air blowing and suction and discharge, the air jet rod 250 sprays air into the packaging drum 600, which facilitates the bottoming out or vaporization and evaporation of residual liquid on the inner wall of the packaging drum 600, and the residue at the bottom is easily removed by suction and discharge.

[0062] The flushing rod 230, the exhaust rod 240, and the air jet rod 250 need to be raised and lowered. Therefore, the flushing rod 230 and the exhaust rod 240 are connected to their respective water pumps via corresponding hoses, and the air jet rod 250 is connected to its corresponding air pump, compressor, or compressed air station / tank via its corresponding hose. (Refer to...) Figure 1 , Figure 2 Conventionally, the first lifting mechanism 210 includes a first lifting plate 220, and a belt motor assembly or a lead screw and nut auxiliary motor assembly that drives the first lifting plate 220 to rise and fall. Therefore, a flushing rod 230, a suction rod 240, and a jetting rod 250 are installed on the first lifting plate 220. (Refer to...) Figure 1 and Figure 2The belt motor combination is adopted, and the motor drives the belt to rotate back and forth to control the lifting of the first lifting plate 220, the flushing rod 230, the pumping rod 240 and the air jet rod 250.

[0063] In addition, the pipe penetrating snake or pipe penetrating track is arranged, the pipe penetrating snake (pipe penetrating track) is used for being penetrated by the hose, one end of the pipe penetrating snake (pipe penetrating track) is fixed at a point deviating from the automatic barrel washing machine 200 of the rack, and the other end is connected to the first lifting plate 220; when the first lifting plate 220 drives the flushing rod 230, the pumping rod 240 and the air jet rod 250 to lift, the pipe penetrating snake (pipe penetrating track) is correspondingly bent, and each hose is limited in the pipe penetrating snake (pipe penetrating track) and is not easy to be folded, so that the hose is prevented from being wound into the belt motor combination.

[0064] With reference to Figure 2 , Figure 3 In some embodiments of the utility model, the flushing rod 230 and the air jet rod 250 are both provided with a plurality of spray holes spaced along the circumferential direction at the lower end peripheral wall, or are provided with rotary spray heads at the lower end.

[0065] With reference to Figure 1 , Figure 2 In some embodiments of the utility model, the barrel washing and conveying section 120 comprises a base 121, a swing seat 122, a swing driving air cylinder 123, and a conveying body 124 arranged on the swing seat 122; the conveying body 124 can be a conveying belt and a motor thereof; the swing seat 122 is a mounting rack of the conveying belt and the motor thereof; the conveying body 124 can also be a plurality of conveying rollers and a motor thereof; the swing seat 122 is a mounting rack of the conveying rollers and the motor thereof; one end of the swing seat 122 is hinged to the base 121, and the other end is hinged to one end of the swing driving air cylinder 123; the other end of the swing driving air cylinder 123 is hinged to the base 121; the swing driving air cylinder 123 is used for driving the packaging barrel 600 on the swing seat 122 to tilt; the lower end of the pumping rod 240 is provided with a suction port 241a; the suction port 241a is used for pumping the liquid at the low place of the tilted inner bottom of the packaging barrel 600; the washing liquid and the soaking liquid in the packaging barrel 600 are sufficiently discharged, thereby greatly ensuring the filling quality of the hydrogen peroxide.

[0066] With reference to Figure 2 , Figure 4 In some embodiments of the utility model, the lower end of the pumping rod 240 is a rubber cylinder 241; the rubber cylinder 241 is provided with a notch at the lower end; the notch penetrates from the peripheral wall of the rubber cylinder 241 to the core channel; the lower end of the rubber cylinder 241 is adapted to elastically abut against the low place of the tilted inner bottom of the packaging barrel 600; and the notch is adapted to serve as the suction port 241a. Therefore, the lower end of the pumping rod 240 can abut against the inner bottom of the packaging barrel 600, and the suction port 241a can sufficiently pump and discharge the residual liquid in the packaging barrel 600; the lower end of the pumping rod 240 is used for elastically abutting against the inner bottom of the packaging barrel 600, and the lowering positioning accuracy of the pumping rod 240 can be relatively rough.

[0067] In practice, the packing barrel 600 does not need to be greatly tilted, and the bottom of the packing barrel 600 is ensured to be tilted to obtain a water collection low point. Therefore, after the packing barrel 600 is filled with water, the friction and even the stop structure 170 can lock the packing barrel 600.

[0068] Referring to Figure 1 , Figure 2 In some embodiments of the present application, a secondary stop structure 180 is further included, the secondary stop structure 180 includes a telescopic rod 181 and a drive stop cylinder 182 for driving the telescopic rod 181 to move, and the telescopic rod 181 is used as a support for the tilted packing barrel 600. Specifically, after the first position detection switch is detected, the central control machine not only instructs the barrel washing section 120 and the first buffer section 110 to pause, but also instructs the drive stop cylinder 182 to make the telescopic rod 181 extend into the limiting transmission channel, and then the central control machine instructs the drive swing cylinder 123 to make the packing barrel 600 at the barrel washing station tilt, and the telescopic rod 181 supports one side of the packing barrel 600.
