Description

Technical Field

[0001] This application relates to the field of packaging machinery technology, and more particularly to capping machines for, for example, vial filling lines. Background Technology

[0002] In the filling production line of food and medicine containers, a capping machine is generally used to cap and seal the filled bottles.

[0003] The conveying process before capping, capping, and post-capping typically requires manual monitoring of products, such as tilting and proper capping, which is cumbersome. It also hinders the timely and efficient detection and handling of defective products.

[0004] Therefore, there is still room for improvement in capping machines. Summary of the Invention

[0005] In order to solve or improve at least one of the technical problems mentioned in the background art, this application provides a capping machine.

[0009] The detection unit includes a stopper detection device and a cap detection device. The stopper detection device is located upstream of the cap hanging part to detect whether the stopper of the container bottle is present before the cap is hung on the container bottle, thereby determining whether the container bottle is tilted. The cap detection device is located downstream of the cap crimping part to detect whether the cap is present after the cap crimping part, thereby determining whether the cap crimping is normal.

[0010] In at least one embodiment, both the stopper detection device and the cap detection device include a photoelectric sensor, which is used to detect whether an object is present at the height position of the stopper and the cap.

[0012] In at least one embodiment, the star wheel gear includes a front waste rejection star wheel and a front waste rejection track disposed upstream of the capping section. The vacuum nozzle on the front waste rejection star wheel adjusts the suction force according to the detection result of the bottle stopper detection device to send the container bottle in the front waste rejection star wheel into the front waste rejection track or the next station of the capping machine's production line.

[0013] In at least one embodiment, the star wheel gear includes a post-rejection star wheel and a post-rejection track disposed downstream of the capping section. The vacuum nozzle on the post-rejection star wheel adjusts the suction force according to the detection result of the bottle cap detection device to send the container bottle in the post-rejection star wheel into the post-rejection track or the next station of the capping machine's production line.

[0014] In at least one embodiment, the capping machine body includes a linear conveying section, which includes a conveyor belt and two oppositely arranged guard plates. The linear conveying section includes a first straight conveying section, an arc conveying section, and a second straight conveying section arranged sequentially along the extending direction of the guard plates. A bottle-collecting gap is provided between the guard plate and the conveyor belt in the arc conveying section, so that the tilted container bottle can leave the linear conveying section through the bottle-collecting gap when passing through the arc conveying section.

[0015] In at least one embodiment, the linear conveying unit further includes a bottle inversion detection module disposed downstream of the second linear conveying section. The bottle inversion detection module includes a photoelectric sensor, which is used to simultaneously detect the height position of the bottle body and the height position of the bottle mouth.

[0016] In at least one embodiment, the capping machine body includes a front linear conveyor located upstream of the capping section and a rear linear conveyor located downstream of the capping section.

The capping section is equipped with a minimum quantity detection device for the inclined slide that detects the flow rate of the cap.

[0017] In at least one embodiment, the capping portion includes a bottle holder rotating assembly and a plurality of bottle holders, the bottle holder rotating assembly comprising:

[0018] A revolution disc axis, wherein the plurality of bottle holders are located in the revolution disc axis and revolve with the revolution disc axis;

[0019] A timing belt surrounds a portion of the bottle holders to drive the bottle holders to rotate. The portion not surrounded by the timing belt is positioned at the intersection of the capping section and its upstream and downstream components, so that the container bottle does not rotate due to the timing belt when entering or leaving the capping section.

[0020] In at least one embodiment, the capping machine further includes a frame assembly and an isolation box, with the main body of the capping machine disposed in the isolation space formed by the frame assembly and the isolation box.

[0021] This application provides a stopper detection device and a cap detection device before and after capping to help determine whether the container bottle is in a normal state before and after capping, which is more timely and efficient than manual inspection. Attached Figure Description

[0044] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0045] This application provides a capping machine.

[0046] In one embodiment of this application, see Figure 1 The capping machine may include a capping machine body 100. The capping machine body 100 is used to realize the functions of feeding, capping, and discharging.

[0047] In one embodiment of this application, see Figures 1 to 3 The capping machine body 100 may include a cap-hanging section 300, a capping section 200, and a detection section 500. The cap-hanging section 300 is used to apply caps to the container bottle 110, and the capping section 200 is used to cap the container bottle 110. The detection section 500 includes a stopper detection device 510 and a cap detection device 520. The stopper detection device 510 is located upstream of the cap-hanging section 300 to detect whether the stopper of the container bottle 110 is present before the cap is applied, thereby determining whether the container bottle 110 is tilted. The cap detection device 520 is located downstream of the capping section 200 to detect whether the cap is present after capping, thereby determining whether the capping was performed correctly.

[0048] This application provides a stopper detection device and a cap detection device before and after capping to help determine whether the container bottle is in a normal state before and after capping, which is more timely and efficient than manual inspection.

[0049] In one embodiment of this application, both the stopper detection device 510 and the cap detection device 520 include photoelectric sensors configured to detect the presence of an object at the height of the stopper and cap. Of course, other methods can also be used to detect stoppers and caps, or to detect whether the container is tilted, properly stoppered, or properly capped.

[0050] In one embodiment of this application, see Figures 1 to 4 The capping section 200 may include a bottle holder 210 and a capping assembly 220, with the container bottle 110 positioned between the bottle holder 210 and the capping assembly 220. The cap attachment section 300 includes a cap application end 310 for applying a cap (e.g., an aluminum cap) to the container bottle 110 before it enters the capping section 300.

[0051] The capping machine body 100 may also include a changing lifting unit 400. The changing lifting unit 400 may include a lifting shaft 401 that can move up and down in the height direction h. The capping assembly 220 and the capping end 310 may be installed on the lifting shaft 401 and move up and down with the lifting shaft 401. The distance between the capping assembly 220 and the bottle holder 210 may change with the movement of the lifting shaft 401, that is, the bottle holder 210 may not be installed on the lifting shaft 401.

[0052] When, for example, the model of container bottle 110 is changed, the container bottle 110 to be capped has a new height dimension, while the position of bottle holder 210 remains unchanged. Therefore, the distance between the capping assembly 220 and the bottle holder 210, and the distance between the capping end 310 and the bottle holder 210, need to be adjusted accordingly. This application integrates the capping assembly 220 and the capping end 310, which need to be adjusted in the height direction h, together via a lifting shaft 401, facilitating simultaneous lifting, lowering, and adjustment during model changes, resulting in higher efficiency.

[0053] The stopper detection device 510 and the cap detection device 520 can also be integrated into the lifting shaft 401. For example, when the height of the container bottle 110 is changed, the height of the stopper and the cap will also change. By integrating the stopper detection device 510 and the cap detection device 520 into the lifting shaft 401, they can be adjusted as a whole, with the same lifting height, avoiding the trouble of adjusting the height one by one.

[0054] In one embodiment of this application, see Figure 1 , Figure 2 and Figure 9 The capping part 200 may include a bottle holder rotation assembly 211 and a bottle holder lifting assembly 212, so that the bottle holder 210 can realize rotation, revolution and lifting movements.

[0055] For example, the capping portion 200 may include a plurality of bottle holders 210 (e.g., 16 bottle holders 210 arranged circumferentially), and the bottle holder rotation assembly 211 may include a rotating disk shaft 2111, in which the plurality of bottle holders 210 are inserted, and the rotation of the rotating disk shaft 2111 drives the bottle holders 210 to rotate. The bottle holder rotation assembly 211 may also include a timing pulley 2112 and a timing belt 2113, the timing belt 2113 surrounding a portion (e.g., 3 / 4) of the bottle holders 210, and the timing pulley 2112 and the timing belt 2113 drive a portion of the bottle holders 210 to rotate. The area not enclosed by the synchronous belt 2113 is set at the intersection of the capping section 200 and its upstream and downstream components (such as the feed star wheel 650 and the discharge star wheel 660, which will be introduced later) to avoid or reduce the displacement of the container bottle 110 caused by the rotation driven by the synchronous belt 3113 when it enters or exits the capping section 200 and has not yet been pressed, thereby avoiding the problem of misalignment and improving the yield.

[0056] The bottle holder lifting assembly 212 may include a cam lifting mechanism 2121, which causes the bottle holder 210 to rise when it revolves to a set position, and the container bottle 110 is clamped to realize the subsequent capping process. When the bottle holder 210 revolves away from the set position, it descends, and the clamped state of the container bottle 110 is released so that it can enter the downstream component (e.g., the discharge star wheel 660).

[0057] The capping section 200 may further include a rotating shaft 230, which can drive the capping assembly 220 and the aforementioned bottle holder rotating assembly 211's revolution shaft 2111 to rotate synchronously. The capping assembly 220 may include a capping knife 2201, a cap pressing head 2202, and a horizontal cam structure. The cap pressing head 2202 corresponds to the bottle holder 210. After the bottle holder lifting assembly 212 lifts the bottle holder 210 and the container bottle 110, the cap pressing head 2202 can abut against the top of the container bottle 110 (bottle cap). After the bottle holder lifting assembly 212 lowers the bottle holder 210 and the container bottle 110, the cap pressing head 2202 leaves the container bottle 110 (bottle cap). The capping knife 2201 can cooperate with the horizontal cam structure. After the container bottle 110 (bottle cap) is pressed by the capping head 2202, the capping knife 2201 can move radially outward under the action of the horizontal cam structure to realize the capping operation.

[0058] In one embodiment of this application, see Figure 3 The cap-hanging part 300 may include a cap-hanging gate 380 located at the cap-applying end 310. The cap-hanging gate 380 includes a cap-feeding channel and an elastic blocking block disposed at the end of the cap-feeding channel. The elastic blocking block protrudes inward in the width direction of the cap-feeding channel and can move inward or outward in the width direction of the cap-feeding channel. This allows it to hold the bottle cap in place, enabling subsequent cap-hanging actions to be performed one by one.

[0059] When the bottle cap moves to the elastic blocking block by gravity, it can be stopped by the elastic blocking block. The bottom of the cap-hanging gate 380 has an opening. When the horizontally moving container bottle 110 passes the capping end 310, the bottle mouth of the container bottle 110 can extend into the cap through the opening, and drive the cap to move in the horizontal direction and squeeze the elastic blocking block. After the elastic blocking block is squeezed to the outside in the width direction, the container bottle 110 takes the cap out (rubs it out) from the cap delivery channel. At this time, the cap is hung on the container bottle 110, realizing the cap hanging function.

[0060] Furthermore, the cap hanging part 300 may also include a pre-feeding system 330, a feeding system 340, an inclined slide 350, and a cap hanging curved channel 360. The bottle caps in the pre-feeding system 330 enter the cap hanging gate 380 in sequence through the feeding system 340, the inclined slide 350, and the cap hanging curved channel 360.

[0061] The pre-feeding system 330 and the feeding system 340 can each be equipped with a minimum quantity detection device 370 for the bottle cap hopper. This device may include an ultrasonic sensor to detect the remaining quantity of bottle caps in the hoppers of the pre-feeding system 330 and the feeding system 340. The inclined slide 350 can be equipped with a minimum quantity detection device 351 for the inclined slide. This device 351 may include a photoelectric sensor to monitor the passing bottle caps, allowing for timely manual intervention and adjustment when the quantity of bottle caps is insufficient.

[0062] The inclined slide 350 is connected to the cap hanging bend channel 360. The inclined slide 350 can be a straight slide inclined to the horizontal plane, so that the bottle cap can move in the inclined slide 350 by gravity.

[0063] The cover-hanging curved channel 360 may include a straight section 363 and a curved section 364, and the end of the cover-hanging curved channel 360 may be connected to the cover-hanging gate 380. The cover-hanging curved channel 360 and the inclined slide 350 may be configured to move relative to each other in the height direction h, so that the covering end 310 where the cover-hanging gate 380 is located can move in the height direction h with the lifting shaft 401.

[0064] Further, see Figure 12 The cap bend channel 360 (particularly in the straight section 363) may include a lateral opening 362. For example, the cross-section of the cap bend channel 360 is U-shaped. The inclined slide 350 extends into the cap bend channel 360 through the lateral opening 362 to transfer the cap into the cap bend channel 360. The opening length of the lateral opening 362 in the height direction h may be greater than the length of the component of the inclined slide 350 that extends into the lateral opening 362, so that the cap bend channel 360 and the inclined slide 350 can move relative to each other in the height direction h while in communication.

[0065] The cover-hanging curved channel 360 may also include a cover-hanging curved channel connecting end 361, through which the lifting shaft 401 can be connected to the cover-applying end 310. More specifically, see... Figure 1 , Figure 3 and Figure 4 The second lifting shaft 4012 (described later) in the lifting shaft 401 can be connected to the connecting end 361 of the hanging cover bend channel through its connecting part 40121.

[0066] In one embodiment of this application, see Figure 4 The lifting and lowering unit 400 may include a lead screw 430 and a lead screw nut 440. The lead screw 430 is rotatably connected to the lead screw nut 440, and the lead screw nut 440 is fixedly connected to the lifting shaft 401. That is, the lifting and lowering action of the lifting rod can be achieved by the cooperation of the lead screw 430 and the lead screw nut 440. Of course, the linear movement of the lifting shaft 401 can also be achieved by other means, for example.

[0067] In one embodiment of this application, see Figure 1 and Figure 4 The changing lifting unit 400 may include multiple lifting shafts 401, such as a first lifting shaft 4011, a second lifting shaft 4012, and a third lifting shaft 4013. The capping assembly 220 can be integrally mounted to or detached from the first lifting shaft 4011 without individually adjusting the height of components such as the capping blade 2201 and the cap pressing head 2202 in the capping assembly 220. For example, the first lifting shaft 4011 may be located at the center of the rotation shaft 230.

[0068] The aforementioned bottle cap detection device 520 can be installed on the second lifting shaft 4012. The aforementioned bottle stopper detection device 510 can be installed on the third lifting shaft 4013.

[0069] Furthermore, the changing lifting unit 400 may include multiple sprockets 420, each sprocket 420 being configured to rotate synchronously. The lead screw 430 may include a first lead screw 431, a second lead screw 432, and a third lead screw 433 fixedly connected to the sprockets 420. Correspondingly, the lead screw nut 440 may include a first lead screw nut 4401 rotatably connected to the first lead screw 431, a second lead screw nut 4402 rotatably connected to the second lead screw 432, and a third lead screw nut 4403 rotatably connected to the third lead screw 433. Through the synchronous rotation of the sprockets 420, the multiple lead screws 430 can rotate synchronously, thereby enabling each lead screw nut 440 and each lifting shaft 401 to rise and fall synchronously.

[0070] In one embodiment of this application, the changing lifting unit 400 may include a chain 410 connected to a plurality of sprockets 420, so that each sprocket 420 can rotate synchronously. Of course, multiple chains 410 may also be used to control multiple sprockets 420 respectively, so that each sprocket 420 rotates synchronously, thereby enabling multiple lead screw nuts 440 to rise or fall synchronously.

[0071] Furthermore, the sprocket 420 may include connecting sprockets for connecting the lead screw nut 440, such as a first sprocket 421, a second sprocket 422, and a third sprocket 423. The first sprocket 421 may be connected to the first lead screw nut 4401, the second sprocket 422 may be connected to the second lead screw nut 4402, and the third sprocket 423 may be connected to the third lead screw nut 4403.

[0072] The sprocket 420 may also include an auxiliary sprocket disposed between the connecting sprockets for tensioning. For example, the sprocket 420 may include a first auxiliary sprocket 424 disposed between the first sprocket 421 and the second sprocket 422, a second auxiliary sprocket 425 disposed between the second sprocket 422 and the third sprocket 423, and a third auxiliary sprocket 426 disposed between the third sprocket 423 and the first sprocket 421. The auxiliary sprockets help adjust the tension of the chain 410, reduce chain bounce and sway, prevent excessive wear and damage to the chain 410, and improve transmission accuracy and lifespan.

[0073] Furthermore, the changing lifting unit 400 may include at least one lifting plate, for example, it may include a first lifting plate 4021 and a second lifting plate 4022. One lifting plate is fixedly connected to at least one lead screw nut 440, for example, the first lifting plate 4021 is simultaneously connected to both a first lead screw nut 4401 and a third lead screw nut 4403. One lifting plate may be fixedly connected to at least one lifting shaft 401, for example, the second lifting plate 4022 is connected to both a second lifting shaft 4012 and a third lifting shaft 4013.

[0074] Furthermore, the lifting unit 400 may also include a hand crank 450 and a reducer 460, which can drive the chain 410 to rotate by manually turning the hand crank 450, thereby raising and lowering the lifting shaft 401. Of course, the lifting shaft 401 can also be raised and lowered by a motor.

[0075] In one embodiment of this application, see Figure 1 and Figure 5The main body 100 of the capping machine may include a star wheel conveyor 600, which may include multiple star wheel gear discs 610. For example, the star wheel gear discs may include a front waste-removing star wheel 620, a transition star wheel 640, a feed star wheel 650, a discharge star wheel 660, and a rear waste-removing star wheel 630 arranged sequentially. The star wheel conveyor 600 may also include structures such as a rotating shaft, bearings, and bearing seats, and is driven to rotate by a power source such as a motor.

[0076] The circumference of the star wheel gear disk 610 can be provided with tooth profiles 611 capable of accommodating the container bottle 110, and vacuum nozzles 612 can be provided in the tooth profiles 611. Exemplarily, the number of tooth profiles 611 on each star wheel gear disk 610 can be equal and correspond one-to-one. By controlling the suction force of the vacuum nozzles 612, the star wheel gear disk 610 can transfer the container bottle 110 to its adjacent component (e.g., another star wheel gear disk 610). For example, when the upstream star wheel gear disk 610 docks with the downstream star wheel gear disk 610, the vacuum nozzle 612 of the tooth profile 611 of the upstream star wheel gear disk 610 stops working, and the vacuum nozzle 612 of the tooth profile 611 of the downstream star wheel gear disk 610 starts working or remains working, so that the container bottle 110 can be transferred from the upstream star wheel gear disk 610 to the downstream star wheel gear disk 610, achieving the purpose of transfer.

[0077] Furthermore, a vacuum gauge capable of detecting suction force can be installed in the vacuum nozzle 612 to facilitate the detection of suction force and determine whether the suction is secure. The vacuum gauge can feed back a negative pressure signal to the vacuum generating device (not shown in the figure) of the vacuum nozzle 612, thereby causing the suction force of the vacuum nozzle 612 to be subject to closed-loop control.

[0078] In one embodiment of this application, see Figure 1 , Figure 5 , Figure 6 and Figure 10 A bottle capping section 200 may be equipped with a bottle cap detection device 510 and a front rejection track 910. For example, a bottle cap detection device 510 and a front rejection track 910 may be installed at the front rejection star wheel. The vacuum nozzle 612 on the front rejection star wheel 620 sends the container bottle 110 into the front rejection track 910 or the next station (e.g., the transition star wheel 640) of the capping machine's production line according to the detection result of the bottle cap detection device 510. For example, if the bottle cap detection device 510 detects that a container bottle 110 has no bottle cap, it determines that it is a waste product. The vacuum nozzle 612 at the corresponding tooth profile 611 of the front rejection star wheel 620 continues to suck when it corresponds to the star wheel of the next station, and stops sucking when it turns to the front rejection track 910, so that the container bottle 110 can enter the front rejection track 910.

[0079] Similarly, a bottle cap detection device 520 and a post-rejection track 920 can be installed downstream of the capping section 200. For example, the bottle cap detection device 520 can be installed at the discharge star wheel 660, and the post-rejection track 920 can be installed at the post-rejection star wheel 630. The vacuum nozzle 612 on the post-rejection star wheel 630 sends the container bottle 110 into the post-rejection track 920 or the next station of the capping machine's production line (e.g., the post-linear conveyor 750, which will be described later) based on the detection result of the bottle cap detection device 520.

[0080] Furthermore, a front waste rejection box 911 can be installed at the end of the front waste rejection track 910, and a rear waste rejection box can be installed at the end of the rear waste rejection track 920, for collecting waste. Detection devices such as waste rejection box presence detection, waste presence detection, and waste rejection box fullness detection can also be installed at the front and rear waste rejection boxes. The front waste rejection star wheel 620 can also be designed as a ratchet to facilitate pushing the waste forward on the front waste rejection track 910.

[0081] In one embodiment of this application, see Figure 10 The capping machine body 100 may also include a guardrail 930, which may be located on the outside of the star wheel conveyor 600 and together with the tooth profile 611 form a space for accommodating the container bottle 110. The guardrail 930 may be formed by processing, for example, a non-metallic material.

[0082] In one embodiment of this application, see Figure 1 , Figure 7 and Figure 8 The capping machine body 100 may include a linear conveyor section 700, which may include a front linear conveyor device 740 and a rear linear conveyor device 750. Container bottles 110 to be capped entering the capping machine body 100 can be transported to the star wheel conveyor section 600 via the front linear conveyor device 740. The star wheel conveyor section 600 then transports the capped container bottles 110 to the rear linear conveyor device 750, realizing a streamlined feeding, capping, and discharging process.

[0083] Further, see Figure 7 The linear conveyor 700 may include a conveyor belt 710 and two opposing guard plates 720. The spacing between the guard plates 720 may be set to be the same as or similar to the diameter of the container bottle 110 to prevent the container bottle 110 from tipping over toward the guard plates 720. For example, the conveyor belt 710 may be a mesh belt, a belt, etc.

[0084] The linear conveyor 700 may include a bottle rejection device 730 disposed upstream of the capping section 200, i.e., the bottle rejection device 730 may be disposed on the front linear conveyor 740. Depending on the extension direction of the channel between the guard plates 720, the bottle rejection device 730 may include a first linear conveyor section 731, an arc conveyor section 732, and a second linear conveyor section 733 arranged sequentially. A bottle collection gap 734 is provided between the guard plates 720 and the conveyor belt 710 in the arc conveyor section 732. When a tilted container bottle 110 passes through the arc conveyor section 732, it can leave the linear conveyor 700 through the bottle collection gap 734 and be rejected, thus realizing the detection and rejection function of the tilted container bottle 110. A bottle collection groove 735 may be provided at the bottle collection gap 734 to collect the rejected container bottle 110.

[0085] Furthermore, a sensor-based bottle-tipping detection module 760 can also be installed on the front linear conveyor 740. The bottle-tipping detection module 760 is located downstream of the bottle-tipping rejection device 730 and is used for secondary detection of bottle tipping conditions to prevent the container bottle 110 from tipping over again after passing through the bottle-tipping rejection device 730. For example, the bottle-tipping detection module 760 may include a photoelectric sensor, and its detection points may include the bottle body and the bottle opening. For instance, if only the bottle body is detected and the bottle opening is not, this is a bottle-tipping signal, and the tipped container bottle can be removed by manual intervention.

[0086] Furthermore, the front linear conveyor 740 can be equipped with a minimum quantity detection device for the linear conveyor section, used to detect the number of containers 110 passing through per unit time (i.e., the flow rate of containers 110) to determine whether there is a shortage of material and control the downstream capping section 200 and other equipment to stop or continue operating. The rear linear conveyor 750 can be equipped with a maximum quantity detection device for the linear conveyor section, used to detect whether containers 110 are continuously present at a certain position to determine whether containers 110 are accumulating and control the upstream components to stop or continue operating. Both the minimum quantity detection device and the maximum quantity detection device for the linear conveyor section can be implemented using photoelectric sensors, which can prevent material shortages or blockages. The rear linear conveyor 750 can also be equipped with a finished product counter for counting the number of finished products.

[0087] In one embodiment of this application, see Figure 11The capping machine may include a frame assembly 820 and an isolation chamber 830. The frame assembly 820 can serve as a mounting carrier for the capping machine body 100, and can be placed on, for example, a factory floor. The isolation chamber 830 can cover the outside of the capping machine body 100, and the bottom of the isolation chamber 830 can be connected to the frame assembly 820 to form an isolation space. The capping machine body 100 can be placed in the isolation space formed by the isolation chamber 830 and the frame assembly 820, which is beneficial for achieving aseptic operation of the capping process. Compared with an aseptic factory, this reduces costs and construction time. For example, the isolation space can be set to positive or negative pressure.

[0088] Furthermore, the frame assembly 820 can be made of several high-strength aluminum alloy and stainless steel materials. The frame assembly 820 may include a platform supporting the main body 100 of the capping machine. The isolation box 830 can be a box structure with an open bottom, welded from stainless steel. Inlet and outlet ports 810 can be provided on both sides of the isolation box 830 to facilitate product loading and unloading. The bottom of the isolation box can be connected to the platform of the frame assembly 820. The area of ​​the bottom opening of the isolation box 830 can be close to or equal to the area of ​​the platform.

[0089] Combination Figure 1 The working process of the capping machine provided in this application may include the following:

[0090] Bottle 110 enters the front linear conveyor 740 and undergoes a two-stage tipping detection process via a tipping rejection device 730 and a tipping detection module to ensure that bottle 110 does not tip over. Bottle 110 is then fed into the front waste rejection star wheel 620, the transition star wheel 640, and the feed star wheel 650. After being capped by the capping part 300 on the feed star wheel 650, it enters the capping part 200 for capping. After capping, bottle 110 exits from the discharge star wheel 660 and the rear waste rejection star wheel 630 into the rear linear conveyor 750, leaving the capping machine and, for example, entering the next station of the filling production line.

[0091] In summary, the capping machine provided in this application has a scientific and reasonable layout, high capping speed, and excellent performance, realizing aseptic production in an isolator environment.

[0092] The above description is the preferred embodiment of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
