Description

Technical Field

[0001] This application relates to the technical field of packaging machinery, and particularly to a capping machine for, for example, a vial filling line. Background Art

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

[0003] Procedures such as conveying before capping, capping, and conveying after capping usually require manual monitoring of the products, such as whether the bottles are toppled or properly capped, which is rather troublesome. It is impossible to detect defective products in a timely and efficient manner for corresponding treatment.

[0004] Therefore, there is still room for improvement in the capping machine. Utility Model Content

[0044] The exemplary implementation modes of the present application will be described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not used to exhaust all feasible ways of the present application, nor to limit the scope of the present application.

[0045] The implementation mode of the present application provides a capping machine.

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

[0047] In one implementation mode of the present application, see Figures 1 to 3 , the capping machine main body 100 may include a cap hanging part 300, a capping part 200, and a detection part 500. The cap hanging part 300 is used to apply a bottle cap to the container bottle 110, and the capping part 200 is used to cap the container bottle 110. The detection part 500 includes a bottle stopper detection device 510 and a bottle cap detection device 520. The bottle stopper detection device 510 is arranged upstream of the cap hanging part 300 to detect whether the bottle stopper of the container bottle 110 is normally present before the container bottle 110 hangs the cap, so as to judge whether the container bottle 110 is overturned. The bottle cap detection device 520 is arranged downstream of the capping part 200 to detect whether the bottle cap is normally present after capping to judge whether capping is normal.

[0048] The present application sets a bottle stopper detection device and a bottle cap detection device before cap hanging and after capping to assist in judging whether the container bottle is in a normal state before and after capping, which is more timely and efficient compared with manual detection.

[0049] In one implementation mode of the present application, both the bottle stopper detection device 510 and the bottle cap detection device 520 include photoelectric sensors, and the photoelectric sensors are configured to detect whether there is an object at the height positions of the bottle stopper and the bottle cap. Of course, the bottle stopper and the bottle cap can also be detected in other forms, or the container bottle can be detected in other forms whether it is overturned, whether there is a stopper correctly, whether capping is correct, etc.

[0050] In an embodiment of the present application, referring to Figures 1 to 4 , the capping part 200 may include a bottle holder 210 and a capping assembly 220. The container bottle 110 is configured to be disposed between the bottle holder 210 and the capping assembly 220. The cap hanging part 300 includes an end for applying a cap 310, and the end for applying a cap 310 is configured to apply a bottle cap (such as an aluminum cap) to the container bottle 110 before the container bottle 110 enters the capping part 300.

[0051] The capping machine main body 100 may further include a changeover lifting part 400. The changeover lifting part 400 may include a lifting shaft 401 that can move up and down in the height direction h. The capping assembly 220 and the end for applying a cap 310 may be mounted 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 can be changed with the lifting and lowering of the lifting shaft 401, that is, the bottle holder 210 is not mounted on the lifting shaft 401.

[0052] For example, when changing the model of the container bottle 110, the container bottle 110 to be capped has a new height dimension. If the position of the bottle holder 210 remains unchanged, the distances between the capping assembly 220 and the bottle holder 210, and between the end for applying a cap 310 and the bottle holder 210 need to be adjusted correspondingly. In the present application, the capping assembly 220 and the end for applying a cap 310 that need to be adjusted in the height direction h are integrated by the lifting shaft 401, which facilitates lifting and lowering together and changeover adjustment, with relatively high efficiency.

[0053] The bottle stopper detection device 510 and the bottle cap detection device 520 may also be integrated on the lifting shaft 401. For example, after changing the height of the container bottle 110, the heights of the bottle stopper and the bottle cap also change. Integrating the bottle stopper detection device 510 and the bottle cap detection device 520 on the lifting shaft 401 can achieve integrated adjustment with the same lifting height, avoiding the trouble of adjusting the height one by one.

[0054] In an embodiment of the present application, referring to 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 achieve self-rotation, revolution, and lifting movements.

[0055] Exemplarily, the capping unit 200 may include a plurality of bottle holders 210 (e.g., 16 bottle holders 210 are arranged on the circumference), and the bottle holder rotating assembly 211 may include a male rotating disk shaft 2111, and the plurality of bottle holders 210 are inserted into the male rotating disk shaft 2111, and the male rotating disk shaft 2111 rotates to drive the bottle holders 210 to rotate. The bottle holder rotating assembly 211 may also include a synchronous wheel 2112 and a synchronous belt 2113, and the synchronous belt 2113 surrounds the outer side of a portion (e.g., 3 / 4) of the bottle holder 210, and the synchronous wheel 2112 and the synchronous belt 2113 drive a portion of the bottle holder 210 to rotate. The position not surrounded by the synchronous belt 2113 is set as the intersection of the capping part 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 situation where the container bottle 110 rotates and moves due to the synchronous belt 3113 when entering or exiting the capping part 200 and has not yet been pressed, thereby avoiding the problem of misalignment and improving the yield rate.

[0056] The bottle holder lifting assembly 212 may include a cam lifting mechanism 2121, so that the bottle holder 210 rises when it revolves to the set position, and the container bottle 110 is pressed to achieve the subsequent capping process. When the bottle holder 210 revolves away from the set position, it descends, and the pressed state of the container bottle 110 is released, so that it can enter the downstream components (such as the discharge star wheel 660).

[0057] The capping part 200 may further include a rotating shaft 230, which may drive the capping assembly 220 and the male turntable shaft 2111 of the bottle holder rotating assembly 211 to rotate synchronously. The capping assembly 220 may include a capping knife 2201, a capping press head 2202, and a horizontal cam structure. The capping press head 2202 corresponds to the position of the bottle holder 210. After the bottle holder lifting assembly 212 drives the bottle holder 210 and the container bottle 110 to rise, the capping press head 2202 can resist the top of the container bottle 110 (bottle cap). After the bottle holder lifting assembly 212 drives the bottle holder 210 and the container bottle 110 to descend, the capping press 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 press head 2202, the capping knife 2201 can move radially outward under the action of the horizontal cam structure to achieve the capping operation.

[0058] In one embodiment of the present application, see Figure 3 The cap hanging part 300 may include a cap hanging gate 380 located at the cap applying end 310, and the cap hanging gate 380 includes a cap delivery channel therein and an elastic blocking block arranged at the end of the cap delivery channel, and the elastic blocking block protrudes inwardly in the width direction of the cap delivery channel and can move inwardly or outwardly in the width direction of the cap delivery channel, so as to be able to clamp the bottle caps and realize the subsequent cap hanging action one by one.

[0059] When the bottle cap moves to the elastic blocking block by gravity, it can be blocked by the elastic blocking block. The bottom of the capping gate 380 has an opening. When the horizontally moving container bottle 110 passes through the capping end 310, the mouth of the container bottle 110 can extend into the bottle cap through the opening, drive the bottle cap to move horizontally 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 out (scrapes out) the bottle cap from the cap feeding channel. At this time, the bottle cap is hung on the container bottle 110 to realize the capping function.

[0060] Further, the capping part 300 may further include a pre-feeding system 330, a feeding system 340, an inclined slideway 350 and a capping bending channel 360. The bottle caps in the pre-feeding system 330 sequentially enter the capping gate 380 through the feeding system 340, the inclined slideway 350 and the capping bending channel 360.

[0061] Wherein, minimum product quantity detection devices 370 for the bottle cap bins can be respectively arranged on the pre-feeding system 330 and the feeding system 340. The minimum product quantity detection devices 370 may include ultrasonic sensors to determine the remaining quantity of the bottle caps by detecting the bins of the pre-feeding system 330 and the feeding system 340. An inclined slideway minimum product quantity detection device 351 can be arranged in the inclined slideway 350. The inclined slideway minimum product quantity detection device 351 may include a photoelectric sensor to monitor the passing bottle caps so that manual intervention and adjustment can be carried out in time when the bottle caps are insufficient.

[0062] The inclined slideway 350 communicates with the capping bending channel 360. The inclined slideway 350 can be a straight slideway inclined to the horizontal plane, so that the bottle caps can move in the inclined slideway 350 by gravity.

[0063] The capping bending channel 360 may include a straight section 363 and a bending section 364. The end of the capping bending channel 360 may be connected to the capping gate 380. The capping bending channel 360 and the inclined slideway 350 may be arranged so that they can move relative to each other in the height direction h, so that the capping end 310 where the capping gate 380 is located can move in the height direction h along with the lifting shaft 401.

[0064] Further, referring to Figure 12 , the capping bending channel 360 (especially in the straight section 363) may include a lateral opening 362. For example, the cross-section of the capping bending channel 360 is formed into a U shape. The inclined slideway 350 extends into the capping bending channel 360 through the lateral opening 362 to realize the transfer of the bottle caps into the capping bending 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 slideway 350 extending into the lateral opening 362, so that the capping bending channel 360 and the inclined slideway 350 can still move relative to each other in the height direction h in the connected state.

[0065] The hanging cover bending channel 360 may further include a hanging cover bending channel connection end 361, and the lifting shaft 401 may be connected to the capping end 310 through the hanging cover bending channel connection end 361. More specifically, referring to Figure 1 , Figure 3 and Figure 4 , the second lifting shaft 4012 (introduced later) in the lifting shaft 401 may be connected to the hanging cover bending channel connection end 361 through its connecting portion 40121.

[0066] In an embodiment of the present application, referring to Figure 4 , the conversion lifting portion 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 movement of the lifting rod can be realized 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 realized in other forms, for example.

[0067] In an embodiment of the present application, referring to Figure 1 and Figure 4 , the conversion lifting portion 400 may include a plurality of lifting shafts 401. For example, it may include a first lifting shaft 4011, a second lifting shaft 4012, and a third lifting shaft 4013. The capping assembly 220 can be integrally mounted on the first lifting shaft 4011 or disassembled from the first lifting shaft 4011, without adjusting the heights of the components such as the capping knife 2201 and the capping head 2202 in the capping assembly 220 one by one. Exemplarily, the first lifting shaft 4011 may be located at the center of the rotating shaft 230.

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

[0069] Furthermore, the conversion lifting portion 400 may include a plurality of sprockets 420, and each sprocket 420 is 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 sprocket 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 synchronous rotation of the plurality of lead screws 430 can be realized, and further the lead screw nuts 440 and the lifting shafts 401 can be lifted and lowered synchronously.

[0070] In an embodiment of the present application, the conversion lifting part 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 can also be used to control multiple sprockets 420 respectively, so that each sprocket 420 rotates synchronously, and further enables a plurality of screw nuts 440 to rise or fall synchronously.

[0071] Further, the sprocket 420 may include a connecting sprocket for connecting the 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 screw nut 4401, the second sprocket 422 may be connected to the second screw nut 4402, and the third sprocket 423 may be connected to the third screw nut 4403.

[0072] The sprocket 420 may further include an auxiliary sprocket for tensioning disposed between the connecting sprockets. For example, the sprocket 420 includes 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 sprocket helps to adjust the tension of the chain 410, reduce the jumping and swinging of the chain 410, avoid excessive wear and damage of the chain 410, and improve the transmission accuracy and service life.

[0073] Further, the conversion lifting part 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 screw nut 440. For example, the first lifting plate 4021 is simultaneously connected to the first screw nut 4401 and the third 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 the second lifting shaft 4012 and the third lifting shaft 4013.

[0074] Further, the conversion lifting part 400 may further include a handwheel 450 and a reducer 460. The chain 410 can be driven to rotate by manually rotating the handwheel 450, so that the lifting shaft 401 rises and falls. Of course, the lifting shaft 401 can also be controlled to rise and fall by a motor.

[0075] In an embodiment of the present application, refer to Figure 1 and Figure 5, the capping machine main body 100 may include a star wheel transmission part 600, and the star wheel transmission part 600 may include a plurality of star wheel tooth discs 610. Exemplarily, the star wheel tooth discs may include a front rejection star wheel 620, a transition star wheel 640, a feeding star wheel 650, a discharging star wheel 660, and a rear rejection star wheel 630 arranged in sequence. The star wheel transmission part 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] On the circumference of the star wheel tooth disc 610, a tooth profile 611 capable of accommodating the container bottle 110 may be provided, and a vacuum suction nozzle 612 may be provided in the tooth profile 611. Exemplarily, the number of tooth profiles 611 on each star wheel tooth disc 610 may be equal and in one-to-one correspondence. By controlling the suction force of the vacuum suction nozzle 612, the star wheel tooth disc 610 can transfer the container bottle 110 to its adjacent component (such as another star wheel tooth disc 610). For example, when the upstream star wheel tooth disc 610 is docked with the downstream star wheel tooth disc 610, the vacuum suction nozzle 612 of the tooth profile 611 of the upstream star wheel tooth disc 610 stops working, and the vacuum suction nozzle 612 of the tooth profile 611 of the downstream star wheel tooth disc 610 starts working or remains working, and the container bottle 110 can be transferred from the upstream star wheel tooth disc 610 to the downstream star wheel tooth disc 610 to achieve the transfer purpose.

[0077] Furthermore, a vacuum gauge capable of detecting the suction force may be provided in the vacuum suction nozzle 612 to facilitate detecting the suction force and determining whether it is firmly sucked. The vacuum gauge can feedback a negative pressure signal to the vacuum generating device (not shown in the figure) of the vacuum suction nozzle 612, thereby prompting the suction force of the vacuum suction nozzle 612 to be under closed-loop control.

[0078] In an embodiment of the present application, refer to Figure 1 , Figure 5 , Figure 6 and Figure 10 , an uncapped bottle detection device 510 and a front rejection track 910 may be provided upstream of the capping part 200. For example, an uncapped bottle detection device 510 and a front rejection track 910 may be provided at the front rejection star wheel. The vacuum suction nozzle 612 on the front rejection star wheel 620 sends the container bottle 110 into the front rejection track 910 or the next working station (such as the transition star wheel 640) of the working assembly line of the capping machine according to the detection result of the uncapped bottle detection device 510. Exemplarily, if the uncapped bottle detection device 510 detects that a certain container bottle 110 has no bottle cap and determines it as a defective product, the vacuum suction nozzle 612 at the corresponding tooth profile 611 of the front rejection star wheel 620 keeps sucking when corresponding to the star wheel of the next working station, and stops sucking when turning to the front rejection track 910, and the container bottle 110 can enter the front rejection track 910.

[0079] Similarly, a bottle cap detection device 520 and a rear rejection track 920 may be provided downstream of the capping section 200, for example, the bottle cap detection device 520 is provided at the discharge star wheel 660, and the rear rejection track 920 is provided at the rear rejection star wheel 630. The vacuum suction nozzle 612 on the rear rejection star wheel 630 delivers the container bottle 110 to the rear rejection track 920 or the next station of the working line of the capping machine (for example, the rear linear conveyor 750, which will be described later) according to the detection result of the bottle cap detection device 520.

[0080] Furthermore, a front waste rejection box 911 may be provided at the end of the front waste rejection track 910, and a rear waste rejection box may be provided at the end of the rear waste rejection track 920 for collecting waste products. Detection devices such as waste rejection box in-place detection, waste product in-place detection, and waste rejection box full material detection may also be provided at the front waste rejection box and the rear waste rejection box. The front waste rejection star wheel 620 may also be provided in the form of a ratchet wheel to facilitate pushing waste products forward on the front waste rejection track 910.

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

[0082] In one embodiment of the present application, see Figure 1 , Figure 7 and Figure 8 The capping machine body 100 may include a linear conveyor 700, and the linear conveyor 700 may include a front linear conveyor 740 and a rear linear conveyor 750. The container bottles 110 to be capped entering the capping machine body 100 may be transported to the star wheel conveyor 600 via the front linear conveyor 740, and the star wheel conveyor 600 transports the capped container bottles 110 to the rear linear conveyor 750, thereby realizing the assembly line feeding, capping, and discharging.

[0083] Further, see Figure 7 The linear conveyor 700 may include a conveyor belt 710 and two oppositely disposed guard plates 720. The spacing between the guard plates 720 may be set to be the same as or close to the diameter of the container bottle 110 to prevent the container bottle 110 from tipping toward the guard plates 720. Exemplarily, the conveyor belt 710 may be a mesh belt, a belt, or the like.

[0084] The linear transfer unit 700 may include an inverted bottle rejection device 730 disposed upstream of the capping unit 200, that is, the inverted bottle rejection device 730 may be provided on the front linear transfer device 740. According to the extension direction of the channel between the guard plates 720, the inverted bottle rejection device 730 may include a first linear conveying section 731, an arc conveying section 732, and a second linear conveying section 733 arranged in sequence. An inverted bottle collection gap 734 is provided between the guard plates 720 and the conveyor belt 710 in the arc conveying section 732. The tilted container bottle 110 can leave the linear transfer unit 700 through the inverted bottle collection gap 734 when passing through the arc conveying section 732, thereby realizing the detection and rejection functions of the tilted container bottle 110. An inverted bottle collection trough 735 may be provided at the inverted bottle collection gap 734 for collecting the rejected container bottles 110.

[0085] Furthermore, an inverted bottle detection module 760 based on sensor detection may also be provided on the front linear transfer device 740. The inverted bottle detection module 760 is disposed downstream of the inverted bottle rejection device 730 and is used for secondary detection of the inverted bottle condition to prevent the container bottle 110 from tilting again after passing through the inverted bottle rejection device 730. Exemplarily, the inverted bottle detection module 760 may include a photoelectric sensor, and its detection sites may include the bottle body and the bottle mouth. For example, when only the bottle body is detected and the bottle mouth is not detected, it is an inverted bottle signal, and the tilted container bottle can be taken out through manual intervention.

[0086] Furthermore, the front linear transfer device 740 may be provided with a minimum quantity detection device for the products in the linear transfer unit, which is used to detect the number of container bottles 110 passing through per unit time (i.e., the flow rate of the container bottles 110) to determine whether there is a shortage of materials and control the shutdown or operation of downstream equipment such as the capping unit 200. The rear linear transfer device 750 may be provided with a maximum quantity detection device for the products in the linear transfer unit, which is used to detect whether the container bottles 110 continuously exist at a certain position to determine whether the container bottles 110 are piled up and control the shutdown or operation of upstream components. The minimum quantity detection device for the products in the linear transfer unit and the maximum quantity detection device for the products in the linear transfer unit can both be realized by photoelectric sensors, which can avoid material shortage or blockage. The rear linear transfer device 750 may also be provided with a finished product counter for counting the number of finished products.

[0087] In an embodiment of the present application, refer to Figure 11, the capping machine may include a frame assembly 820 and an isolation box 830. The frame assembly 820 can serve as the installation carrier of the capping machine main body 100 and be placed on, for example, the factory floor. The isolation box 830 can cover the outside of the capping machine main body 100. The bottom of the isolation box 830 can be connected to the frame assembly 820 to form an isolation space. The capping machine main body 100 can be arranged in the isolation space formed by the isolation box 830 and the frame assembly 820, which is conducive to realizing the asepticization of the capping process. Compared with an aseptic workshop, it reduces the cost and construction period. Exemplarily, the isolation space can be set to positive pressure or negative pressure.

[0088] Further, the frame assembly 820 can be composed of several high-strength aluminum alloy materials and stainless steel materials. The frame assembly 820 can include a platen for carrying the capping machine main body 100. The isolation box 830 can be a box structure with an open bottom welded by stainless steel materials. Feed ports and a discharge port 810 can be opened on both sides of the isolation box 830 to facilitate the entry and exit of products. The bottom of the isolator box can be connected to the platen of the frame assembly 820. The bottom opening area of the isolation box 830 can be close to or equal to the area of the platen.

[0089] Combined Figure 1 , the working process of the capping machine provided by this application can include the following content.

[0090] The container bottle 110 enters the front linear conveying device 740 and undergoes two-stage inverted bottle detection by the inverted bottle rejection device 730 and the inverted bottle detection module to ensure that the container bottle 110 does not topple. The container 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 the capping part 300 hangs a cap on the feed star wheel 650, it enters the capping part 200 for capping treatment. The capped container bottle 110 enters the rear linear conveying device 750 from the discharge star wheel 660 and the rear waste rejection star wheel 630 and leaves the capping machine, for example, entering the next station of the filling production line.

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

[0092] The above are the preferred embodiments of this application. It should be noted that for those skilled in the art, without departing from the principle of this application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this application.
