DETAILED DESCRIPTION

[0053] The exemplary embodiments of the present application will be described hereinafter with reference to the accompanying drawings. It is to be understood that the specific description is only for the purpose of teaching the skilled in the art how to implement the present application, and is not intended to exhaust all possible ways of the present application, nor to limit the scope of the present application.

[0054] The embodiments of the present application provide a capping machine.

[0055] In one embodiment of the present application, referring to FIG. 1, the capping machine can include a capping machine main body 100. The capping machine main body 100 is used to realize the functions of feeding, capping and discharging.

[0056] In an embodiment of the present application, referring to FIGS. 1-4, the capping machine body 100 can include a capping section 200, a cap hanging section 300, and a change-over lifting section 400. The capping section 200 can include a bottle holder 210 and a capping assembly 220, and the container bottle 110 is arranged between the bottle holder 210 and the capping assembly 220. The cap hanging section 300 includes a cap applying end 310 for applying a bottle cap (e.g. an aluminum cap) to the container bottle 110 before the container bottle 110 enters the capping section 200. The change-over lifting section 400 can include a lifting shaft 401 that can be lifted in a height direction h, and the capping assembly 220 and the cap applying end 310 are mounted on the lifting shaft 401 and lifted with the lifting shaft 401, and the distance between the capping assembly 220 and the bottle holder 210 can be changed with the lifting of the lifting shaft 401, i.e. the bottle holder 210 is not mounted on the lifting shaft 401.

[0057] When, for example, the model of the container bottle 110 is changed, the container bottle 110 to be capped has a new height dimension, and the position of the bottle holder 210 does not change, so the distance between the capping assembly 220 and the bottle holder 210 and the distance between the cap applying end 310 and the bottle holder 210 need to be adjusted accordingly. The present application integrates the capping assembly 220 and the cap applying end 310 that need to be adjusted in the height direction h together by means of the lifting shaft 401, which facilitates lifting and change-over adjustment together, and is more efficient.

[0058] In an embodiment of the present application, referring to FIGS. 1 and 4, the capping machine body 100 can include a detection section 500, which can include a bottle plug detection device 510 and a bottle cap detection device 520. The bottle plug detection device 510 is located upstream of the cap hanging section 300 and is used to detect whether the bottle plug is normally present before the container bottle 110 is capped. The bottle cap detection device 520 is located downstream of the capping section 200 and is used to detect whether the bottle cap is normally present after the container bottle 110 leaves the capping section 200. Both the bottle plug detection device 510 and the bottle cap detection device 520 can be mounted on the lifting shaft 401. Both the bottle plug detection device 510 and the bottle cap detection device 520 can include a photoelectric sensor configured to detect whether there is an object at the height position of the bottle plug and the bottle cap. Of course, the bottle plug and the bottle cap can also be detected in other forms, or the container bottle can also be detected in other forms to determine whether it is tilted, whether it has a plug, whether it is capped correctly, etc.

[0059] Similarly, after the height of the container bottle 110 is changed, for example, the heights of the bottle plug and the bottle cap will also change, and integrating the bottle plug 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.

[0060] In one embodiment of the present application, referring to FIG. 1, FIG. 2 and FIG. 9, the capping section 200 can include a bottle holder rotating assembly 211 and a bottle holder lifting assembly 212, so that the bottle holder 210 can realize rotation, revolution and lifting motion.

[0061] For example, the capping section 200 can include a plurality of bottle holders 210 (for example, 16 bottle holders 210 arranged on the circumference), the bottle holder rotating assembly 211 can include a revolution shaft 2111, the plurality of bottle holders 210 are inserted into the revolution shaft 2111, and the revolution shaft 2111 rotates to drive the bottle holders 210 to revolve. The bottle holder rotating assembly 211 can further include a synchronous wheel 2112 and a synchronous belt 2113, the synchronous belt 2113 surrounds the outside of part (for example, 3 / 4) of the bottle holders 210, and the synchronous wheel 2112 and the synchronous belt 2113 drive part of the bottle holders 210 to rotate. The position not surrounded by the synchronous belt 2113 is arranged at the intersection of the capping section 200 and its upstream and downstream components (for example, the feeding star wheel 650 and the discharging star wheel 660, which will be described later), so as to avoid or reduce the self-rotation and displacement of the container bottles 110 when entering and leaving the capping section 200 and not being compressed, thereby avoiding the misalignment problem and improving the yield.

[0062] The bottle holder lifting assembly 212 can include a cam lifting mechanism 2121, so that the bottle holder 210 is lifted when revolving to the setting position, the container bottle 110 is compressed, and the subsequent capping process is realized. When the bottle holder 210 revolves away from the setting position, the bottle holder 210 is lowered, and the compression state of the container bottle 110 is released, so as to be able to enter the downstream components (for example, the discharging star wheel 660).

[0063] The capping section 200 can further include a rotating shaft 230, which can drive the capping assembly 220 and the revolution shaft 2111 of the aforementioned bottle holder rotating assembly 211 to rotate synchronously. The capping assembly 220 can include a capping knife 2201, a cap pressing head 2202 and a horizontal cam structure. The cap pressing head 2202 corresponds to the position of the bottle holder 210, and after the bottle holder lifting assembly 212 drives the bottle holder 210 and the container bottle 110 to rise, the cap pressing head 2202 can abut against 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 cap pressing head 2202 leaves the container bottle 110 (bottle cap). The capping knife 2201 can cooperate with the horizontal cam structure, and after the container bottle 110 (bottle cap) is abutted by the cap pressing head 2202, the capping knife 2201 can move to the radial outside under the action of the horizontal cam structure, so as to realize the capping operation.

[0064] In one embodiment of the present application, referring to FIG. 3, the cap hanging part 300 can include a cap hanging shutter 380 at the cap applying end 310, the cap hanging shutter 380 including a cap feeding channel therein and an elastic blocking block provided at the end of the cap feeding channel, the elastic blocking block protruding to the inside of the width direction of the cap feeding channel and being able to move inwardly or outwardly in the width direction of the cap feeding channel. The bottle cap can be clamped thereby to realize the subsequent one-by-one cap hanging action.

[0065] The bottle cap can be clamped by the elastic blocking block when the bottle cap moves to the elastic blocking block by gravity. The bottom of the cap hanging shutter 380 has an opening, when the container bottle 110 horizontally moves through the cap applying end 310, the bottle mouth of the container bottle 110 can extend into the bottle cap through the opening, and drive the bottle cap to move in the horizontal direction and press the elastic blocking block, after the elastic blocking block is pressed to the outside in the width direction, the container bottle 110 will take out (rub out) the bottle cap from the cap feeding channel, and the bottle cap is hung on the container bottle 110 at this time, realizing the cap hanging function.

[0066] Further, the cap hanging part 300 can further 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 pass through the feeding system 340, the inclined slide 350 and the cap hanging curved channel 360 in turn and enter the cap hanging shutter 380.

[0067] The pre-feeding system 330 and the feeding system 340 can be respectively provided with a bottle cap warehouse product minimum amount detection device 370, which can include an ultrasonic sensor to detect the warehouse of the pre-feeding system 330 and the feeding system 340 to determine the remaining amount of the bottle caps. The inclined slide 350 can be provided with an inclined slide product minimum amount detection device 351, which can include a photoelectric sensor to monitor the passing bottle caps so that manual intervention can be adjusted in time when the bottle caps are insufficient.

[0068] The inclined slide 350 is connected to the cap hanging curved channel 360, and 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.

[0069] The cap hanging curved channel 360 can include a straight section 363 and a curved section 364, and the end of the cap hanging curved channel 360 can be connected to the cap hanging shutter 380. The cap hanging curved channel 360 and the inclined slide 350 can be arranged to be relatively movable in the height direction h, so that the cap applying end 310 where the cap hanging shutter 380 is located can move in the height direction h along with the lifting shaft 401.

[0070] Further, referring to FIG. 12, the cap-bending channel 360 (especially at the straight section 363) can include a lateral opening 362. For example, the cap-bending channel 360 is formed in a U-shape in cross section. The inclined slide 350 extends into the cap-bending channel 360 through the lateral opening 362 to achieve the transfer of the cap into the cap-bending channel 360. The opening length of the lateral opening 362 in the height direction h can be greater than the length of the part of the inclined slide 350 extending into the lateral opening 362, so that the cap-bending channel 360 and the inclined slide 350 can also move relative to each other in the height direction h in a state of communication.

[0071] The cap-bending channel 360 can also include a cap-bending channel connecting end 361, through which the lifting shaft 401 can be connected to the cap- applying end 310. More specifically, referring to FIGS. 1, 3 and 4, the second lifting shaft 4012 (to be described later) of the lifting shaft 401 can be connected to the cap-bending channel connecting end 361 through the connecting part 40121 thereof.

That is, the lifting action of the lifting shaft 401 can be achieved by the cooperation of the lead screw 430 and the lead screw nut 440. Of course, the linear motion of the lifting shaft 401 can also be achieved by other forms, for example.

[0073] In an embodiment of the present application, referring to FIGS. 1 and 4, the profile-changing lifting part 400 can include a plurality of lifting shafts 401, for example, a first lifting shaft 4011, a second lifting shaft 4012 and a third lifting shaft 4013. The cap-rolling assembly 220 can be integrally mounted to or detached from the first lifting shaft 4011, without the need to adjust the height of each component in the cap-rolling assembly 220, such as the cap-rolling knife 2201, the cap-pressing head 2202, etc. Exemplarily, the first lifting shaft 4011 can be located at the center of the rotating shaft 230.

[0074] The aforementioned cap-detecting device 520 can be mounted to the second lifting shaft 4012. The aforementioned plug-detecting device 510 can be mounted to the third lifting shaft 4013.

[0075] Further, the shape-changing lifting part 400 can include a plurality of sprockets 420, each of which is configured to rotate synchronously. The lead screws 430 can 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 nuts 440 can 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 synchronous rotation of the sprockets 420, synchronous rotation of the plurality of lead screws 430 can be achieved, and in turn, synchronous lifting of each of the lead screw nuts 440 and each of the lifting shafts 401 can be achieved.

[0076] In an embodiment of the present application, the shape-changing lifting part 400 can include a chain 410 connected to the plurality of sprockets 420, so that each of the sprockets 420 can rotate synchronously. Of course, a plurality of chains 410 can also be used to control the plurality of sprockets 420 respectively, so that each of the sprockets 420 rotates synchronously, and in turn, the plurality of lead screw nuts 440 can be lifted or lowered synchronously.

[0077] Further, the sprockets 420 can include connecting sprockets for connecting the lead screw nuts 440, such as a first sprocket 421, a second sprocket 422, and a third sprocket 423. The first sprocket 421 can be connected to the first lead screw nut 4401, the second sprocket 422 can be connected to the second lead screw nut 4402, and the third sprocket 423 can be connected to the third lead screw nut 4403.

[0078] The sprockets 420 can also include auxiliary sprockets for tensioning arranged between the connecting sprockets. For example, the sprockets 420 include a first auxiliary sprocket 424 arranged between the first sprocket 421 and the second sprocket 422, a second auxiliary sprocket 425 arranged between the second sprocket 422 and the third sprocket 423, and a third auxiliary sprocket 426 arranged between the third sprocket 423 and the first sprocket 421. The auxiliary sprockets help 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 accuracy and service life of the transmission.

[0079] Further, the shape-changing lifting part 400 can include at least one lifting plate, such as 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, such as the first lifting plate 4021 connected to the first lead screw nut 4401 and the third lead screw nut 4403. One lifting plate can be fixedly connected to at least one lifting shaft 401, such as the second lifting plate 4022 connected to the second lifting shaft 4012 and the third lifting shaft 4013.

[0080] Further, the shape-changing lifting part 400 can further include a hand wheel 450 and a speed reducer 460. The chain 410 can be driven to rotate by rotating the hand wheel 450 manually, so as to drive the lifting shaft 401 to lift. Of course, the lifting shaft 401 can also be controlled to lift by a motor.

[0082] The circumference of the star wheel toothed disc 610 can be provided with a tooth profile 611 capable of accommodating the container bottle 110, and the tooth profile 611 can be provided with a vacuum suction nozzle 612. Exemplarily, the number of tooth profiles 611 on each star wheel toothed disc 610 can be equal and one-to-one corresponding. By controlling the suction force of the vacuum suction nozzle 612, the star wheel toothed disc 610 can convey the container bottle 110 to its adjacent component (for example, another star wheel toothed disc 610). For example, when the upstream star wheel toothed disc 610 is docked with the downstream star wheel toothed disc 610, the vacuum suction nozzle 612 of the tooth profile 611 of the upstream star wheel toothed disc 610 stops working, and the vacuum suction nozzle 612 of the tooth profile 611 of the downstream star wheel toothed disc 610 starts working or keeps working, so that the container bottle 110 can be transferred from the upstream star wheel toothed disc 610 to the downstream star wheel toothed disc 610, achieving the conveying purpose.

[0083] Further, the vacuum suction nozzle 612 can be provided with a vacuum gauge capable of detecting the suction force, so as to facilitate detection of the suction force and determination of whether the suction is firm. The vacuum gauge can feed back a negative pressure signal to a vacuum generating device (not shown in the figure) of the vacuum suction nozzle 612, so as to promote closed-loop control of the suction force of the vacuum suction nozzle 612.

[0084] In one embodiment of the present application, referring to FIG. 1, FIG. 5, FIG. 6 and FIG. 10, a bottle plug detection device 510 and a front scrap track 910 can be arranged upstream of the capping section 200. For example, the bottle plug detection device 510 and the front scrap track 910 can be arranged at the front scrap star wheel. The vacuum suction nozzles 612 on the front scrap star wheel 620 can send the container bottles 110 to the front scrap track 910 or the next station (e.g. the transition star wheel 640) of the working line of the capping machine according to the detection result of the bottle plug detection device 510. For example, if the bottle plug detection device 510 detects that a container bottle 110 has no bottle plug, it is determined as a defective product. The vacuum suction nozzle 612 at the corresponding tooth profile 611 of the front scrap star wheel 620 can keep suctioning when corresponding to the star wheel of the next station, and stop suctioning when turning to the front scrap track 910, so that the container bottle 110 can enter the front scrap track 910.

[0085] Similarly, a bottle cap detection device 520 and a rear scrap track 920 can be arranged downstream of the capping section 200. For example, the bottle cap detection device 520 can be arranged at the discharge star wheel 660, and the rear scrap track 920 can be arranged at the rear scrap star wheel 630. The vacuum suction nozzles 612 on the rear scrap star wheel 630 can send the container bottles 110 to the rear scrap track 920 or the next station (e.g. the rear linear conveying device 750, which will be described later) of the working line of the capping machine according to the detection result of the bottle cap detection device 520.

[0086] Further, the end of the front scrap track 910 can be provided with a front scrap box 911, and the end of the rear scrap track 920 can be provided with a rear scrap box for collecting defective products. Detection devices such as scrap box in position detection, defective product in position detection and scrap box full detection can also be arranged at the front scrap box and the rear scrap box. The front scrap star wheel 620 can also be arranged in the form of a ratchet wheel to facilitate the advancement of the defective products on the front scrap track 910.

[0087] In one embodiment of the present application, referring to FIG. 10, the capping machine body 100 can further include a guard rail 930, which can be arranged outside the star wheel conveying section 600 together with the tooth profile 611 to form a space for accommodating the container bottles 110. The guard rail 930 can be formed by processing a non-metallic material, for example.

[0088] In one embodiment of the present application, referring to FIG. 1, FIG. 7 and FIG. 8, the capping machine body 100 can include a linear conveying section 700, which can include a front linear conveying device 740 and a rear linear conveying device 750. The container bottles 110 to be capped entering the capping machine body 100 can be conveyed to the star wheel conveying section 600 by the front linear conveying device 740, and the capped container bottles 110 can be delivered to the rear linear conveying device 750 by the star wheel conveying section 600, so as to realize the flow line feeding, capping and discharging.

[0089] Further, referring to FIG. 7, the linear conveying section 700 can include a conveying belt 710 and two opposing guards 720. The distance between the guards 720 can be set to be the same as or close to the diameter of the container bottle 110, preventing the container bottle 110 from tilting towards the guards 720. Exemplarily, the conveying belt 710 can be a mesh belt, a belt, or the like.

[0090] The linear conveying section 700 can include a bottle-tilting rejection device 730 arranged upstream of the capping section 200, i.e. the bottle-tilting rejection device 730 can be arranged on the front linear conveying device 740. According to the extension direction of the passage between the guards 720, the bottle-tilting rejection device 730 can include a first linear conveying segment 731, an arc conveying segment 732, and a second linear conveying segment 733 arranged in sequence, and a bottle-tilting collection gap 734 can be arranged between the guards 720 and the conveying belt 710 in the arc conveying segment 732. The tilted container bottle 110 can exit the linear conveying section 700 from the bottle-tilting collection gap 734 when passing through the arc conveying segment 732, achieving the detection and rejection function of the tilted container bottle 110. A bottle-tilting collection groove 735 can be arranged at the bottle-tilting collection gap 734 to collect the rejected container bottle 110.

[0091] Further, the front linear conveying device 740 can also be provided with a bottle-tilting detection module 760 based on sensor detection. The bottle-tilting detection module 760 is arranged downstream of the bottle-tilting rejection device 730 (e.g. downstream of the second linear conveying segment 733), for secondary detection of the bottle-tilting condition, preventing the container bottle 110 from tilting again after passing through the bottle-tilting rejection device 730. Exemplarily, the bottle-tilting detection module 760 can include a photoelectric sensor, and the detection points can 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 a bottle-tilting signal, and the tilted container bottle can be removed by manual intervention.

[0092] Further, the front linear conveying device 740 can be provided with a linear conveying section product minimum quantity detection device for detecting the number of container bottles 110 passing per unit time (i.e. the flow of container bottles 110), to determine whether there is a shortage of materials, and control the shutdown or continued operation of the downstream capping section 200 and other equipment. The rear linear conveying device 750 can be provided with a linear conveying section product maximum quantity detection device for detecting whether the container bottles 110 continuously exist at a certain position, to determine whether the container bottles 110 are accumulated, and control the shutdown or continued operation of the upstream components. Both the linear conveying section product minimum quantity detection device and the linear conveying section product maximum quantity detection device can be implemented by photoelectric sensors, which can avoid material shortage or blockage. The rear linear conveying device 750 can also be provided with a finished product counter for counting the number of finished products.

[0093] In one embodiment of the present application, referring to FIG. 11, the capping machine can include a rack assembly 820 and an isolator box 830. The rack assembly 820 can serve as a mounting carrier of the capping machine body 100, and be placed on the ground of a factory building, for example. The isolator box 830 can be covered on the outside of the capping machine body 100, and the bottom of the isolator box 830 can be connected to the rack assembly 820 to form an isolated space. The capping machine body 100 can be arranged in the isolated space formed by the isolator box 830 and the rack assembly 820, which is conducive to achieving the sterilization of the capping process. Compared with a sterile factory, the cost and construction period are reduced. Exemplarily, the isolated space can be set to a positive pressure or a negative pressure.

[0094] Further, the rack assembly 820 can be made of several high-strength aluminum alloy materials and stainless steel materials. The rack assembly 820 can include a table plate for carrying the capping machine body 100. The isolator box 830 can be a box structure with an open bottom made of stainless steel material, and the two sides of the isolator box 830 can be provided with an inlet and an outlet 810 for facilitating the entry and exit of products. The bottom of the isolator box can be connected to the table plate of the rack assembly 820. The opening area of the bottom of the isolator box 830 and the area of the table plate can be close to or equal to each other.

[0095] In combination with FIG. 1, the working process of the capping machine provided by the present application can include the following contents.

[0096] The container bottle 110 enters the front linear conveying device 740, passes through the bottle tipping and removing device 730 and the two-stage bottle tipping detection of the bottle tipping detection module, and ensures that the container bottle 110 does not tip. The container bottle 110 is then sent to the front removing star wheel 620, the transition star wheel 640, and the feeding star wheel 650, and after being capped by the capping part 300, enters the capping part 200 for capping treatment. The capped container bottle 110 enters the rear linear conveying device 750 from the discharging star wheel 660 and the rear removing star wheel 630, and leaves the capping machine, for example, enters the next station of the filling production line.

[0097] In summary, the capping machine provided by the present application has a scientific and reasonable layout, high capping speed, and excellent performance, and realizes sterile production in an isolator environment.

[0098] The above describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
