Description

Technical Field

[0001] This application relates to the technical field of beverage packaging, and particularly to a fully automatic capping device for beverage bottles with intelligent vision positioning. Background Art

[0002] The automatic capping device for beverage bottles plays a crucial role in modern production lines. It can quickly and accurately screw the bottle caps onto the beverage bottles, reduce manual intervention, and increase the production speed. It not only improves production efficiency and product quality but also reduces production costs, ensures the consistency of product quality, and can precisely control the capping force to ensure the sealing of each bottle of beverage, prevent microorganisms from entering the bottle, and reduce the risk of beverage contamination.

[0003] Although the existing capping machines can automatically screw the caps of beverage bottles tightly, during the screwing process, due to insufficient mechanical positioning accuracy, the success rate of capping decreases, and the unqualified products need to be reworked, increasing production costs. Moreover, there are differences in the movement of the bottle bodies and caps of beverage bottles, and the existing capping machines have a single adaptation object and are difficult to screw the bottle bodies and caps of beverage bottles with different shapes. In addition, during the screwing process, the caps are likely to be skewed when placed on the bottle mouths, and the cap fixing device cannot timely position and fix the caps when the beverage bottles enter the capping device. Since the beverage bottles rotate in the capping device and rotation generates centrifugal force, the beverage bottles and caps will be skewed and offset under the influence of centrifugal force during rotation, resulting in misaligned teeth during screwing, reducing the capping qualification rate, and unable to separate the beverage bottles with abnormal sealing.

[0004] Therefore, we propose a fully automatic capping device for beverage bottles with intelligent vision positioning to solve the above problems. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of this application is to improve the positioning accuracy of beverage bottles entering the capping device, adapt to different specifications of caps by setting replaceable fixing covers, adapt to different beverage bottles by adjusting the height of the screwing parts, improve the capping success rate by keeping the caps horizontal, and take away the beverage bottles with abnormal sealing such as misaligned teeth with too short screwing time and overtoothed caps with too long screwing time through monitoring, and automatically separate the unqualified products, providing a fully automatic capping device for beverage bottles with intelligent vision positioning compared with the prior art.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions.

[0007] An automatic beverage bottle capping device with intelligent vision positioning, comprising a conveyor belt, a limiting plate located above the conveyor belt, variable track frames located on both sides of the limiting plate, and a bottom plate.

The first spring is sleeved outside the sliding rod and fixedly connected between the first permanent magnet and the first electromagnet. The fixing cover is threadedly connected to the bottom of the sliding rod.

[0008] Furthermore, a first piston, an adsorption plate, a second spring, a second piston, a clamping plate, and a communication pipe are further arranged on the fixing cover; The first piston is fixedly connected to the inner top wall of the fixing cover in an embedded manner. The adsorption plate is fixedly connected to the movable end of the first piston. The second spring is fixedly connected between the adsorption plate and the first piston. Multiple groups of second pistons are provided. The second pistons are fixedly connected to the inner side wall of the fixing cover in an embedded manner. The clamping plate is fixedly connected to the movable end of the second piston. The two ends of the communication pipe respectively penetrate through the top and side wall of the fixing cover and are fixedly communicated with the first piston and the second piston.

[0009] Furthermore, a plurality of suction cups are arranged on the bottom surface of the adsorption plate, and an anti-slip layer is arranged on the surface of the clamping plate.

[0010] Furthermore, a servo motor is fixedly installed in the middle of the bottom plate. The output end of the servo motor is fixedly connected to a connecting rod. The upper end of the connecting rod is fixedly connected to the mounting frame. A limiting sliding sleeve is fixedly sleeved on the outer wall of the connecting rod. An installation table is arranged above the bottom plate. The limiting sliding sleeve penetrates through the installation table and is slidably connected to the installation table.

[0011] Furthermore, an adjusting member is arranged below the installation table. The adjusting member includes a cylinder, an elastic telescopic rod, a slider, and a chute; The cylinder and the elastic telescopic rod are both fixedly connected to the bottom plate. Multiple groups of elastic telescopic rods are provided. Multiple sliders are provided. The top of the cylinder and each elastic telescopic rod is fixedly connected to a slider. The chute is fixedly connected to the bottom of the installation table. The slider is slidably connected to the chute.

[0012] Furthermore, the tightening member includes a bearing platform, a bearing seat, a rotating shaft, a baffle, a gear, a toothed ring, a second permanent magnet, a second electromagnet, a timer, and a speed sensor; The carrier table is provided with several groups and is fixedly connected to the top of the installation table. The carrier seat is fixedly connected to the top of the rotating shaft. The rotating shaft penetrates through the installation table and is rotatably connected to the carrier table. The baffle is fixedly connected to the lower end of the rotating shaft. The gear is sleeved on the outer side of the rotating shaft and is in damping sliding connection with the rotating shaft. The gear ring is fixedly connected to the bottom plate. Several gears are all meshed with the gear ring. The permanent magnet II is sleeved on the outer side of the rotating shaft and is fixedly connected to the upper end of the gear. The electromagnet II is sleeved on the outer side of the rotating shaft and is fixedly connected to the bottom of the installation table. The timer and the speed measurement sensor are both arranged on the installation table. The timer and the speed measurement sensor are both controlled and connected to the electromagnet II through the controller.

[0013] Furthermore, a pressure sensor is inlaid in the middle of the carrier seat. The pressure sensor is controlled and connected to the electromagnet II through the controller.

[0014] Furthermore, a protective cover is fixedly connected to the bottom plate. The installation table is located inside the protective cover.

[0015] Furthermore, a plurality of infrared emitters are arranged on the orbit-changing frame. Two infrared receivers are symmetrically arranged on the protective cover. The infrared emitters are located below the infrared receivers. The infrared receivers are controlled and connected to the electromagnet I through the controller.

[0016] Compared with the prior art, the advantages of this application are as follows: (1) By setting the bottle cap fixing part, when the electromagnet I is powered on, it attracts the permanent magnet I, drives the permanent magnet I, the sliding rod and the fixed cover to move downward, so that the bottle cap enters the inside of the fixed cover. After the bottle cap enters the inside of the fixed cover, the fixed cover continues to move downward, and the bottle cap presses the adsorption plate, so that the gas in the piston I is squeezed through the connecting pipe into the piston II, thereby driving the middle of the clamping plate box to move and clamping and fixing the bottle cap, and pressing the bottle cap from the top, making the bottle cap more stable when being tightened.

[0017] (2) By setting the adjusting part, starting the cylinder drives the installation table to slide up and down on the outer side of the limit sliding sleeve, thereby driving the tightening part to move up and down, and adjusting the distance between the tightening part and the bottle cap fixing part. Therefore, the height of the tightening part can be adjusted according to the height of the beverage bottle to adapt to beverage bottles of different heights, making the device more adaptable.

[0018] (3) By setting a tightening member, the servo motor operates to drive the mounting table and the connecting rod to rotate, thereby driving the fixed cover on the mounting frame and the bearing table on the mounting table to rotate. In this way, the beverage bottle and the bottle cap can revolve around the central axis of the mounting table. When the fixed cover descends to press the bottle cap tightly, the pressure sensor on the bearing seat detects an increase in pressure. When the pressure reaches the threshold value, the electromagnet two is activated through the controller. At this time, the magnetic poles of the mutually approaching sides of the electromagnet two and the permanent magnet two are the same, and the electromagnet two repels the permanent magnet two, driving the gear to move downward to engage with the gear ring. At this time, during the revolution process, the gear can also rotate around its own central axis, thereby driving the bearing table and the beverage bottle thereon to rotate, causing relative rotation between the beverage bottle and the bottle cap, and thus tightening the beverage bottle and the bottle cap.

[0019] (4) By setting a plurality of infrared emitters on the orbit-changing frame and infrared receivers on the protective cover, when transferring the beverage bottle from the conveyor belt to the bearing table for tightening, during the rotation of the orbit-changing frame on one side, the plurality of infrared emitters are driven to continuously pass below the infrared receivers. When the infrared emitter rotates directly below the infrared receiver, the infrared receiver receives the signal and activates the electromagnet one, driving the fixed cover to descend to clamp and fix the bottle cap. When transferring the tightened beverage bottle from the bearing table to the conveyor belt, during the rotation of the orbit-changing frame on the other side, the plurality of infrared emitters are driven to continuously pass below the infrared receivers. When the infrared emitter rotates directly below the infrared receiver, the infrared receiver receives the signal and turns off the electromagnet one, driving the fixed cover to rise to release the fixation of the bottle cap, thereby realizing the automatic loading and unloading of the beverage bottle and enabling precise positioning, so that the beverage bottle can be immediately fixed when transferred to the bearing table and the fixation is released only before leaving the bearing table. After the fixation is released, it can immediately leave the bearing table, making the tightening operation of the beverage bottle more stable.

[0020] (5) When the bottle cap is being tightened, if there is a misalignment situation, then the bottle cap will get stuck and unable to rotate further after rotating one circle, resulting in an illusion that the bottle cap has been tightened. In this case, the timer will detect that the rotation time of the gear is too short, and thus activate the manipulator through the controller to pick up the beverage bottle with abnormal sealing and transfer it to the conveying device for unqualified beverage bottles. When the bottle cap has a damaged tooth situation, the bottle cap will keep rotating and unable to stop. At this time, the timer will detect that the rotation time of the gear is too long, and also activate the manipulator through the controller to pick up the beverage bottle with abnormal sealing and transfer it to the conveying device for unqualified beverage bottles, automatically separating unqualified products.

[0021] (6) By threadedly connecting the fixed cover to the bottom of the sliding rod, the fixed cover can be replaced according to the size of the bottle cap, so that more different specifications and models of beverage bottles and bottle caps can be tightened, making the device more adaptable.

[0022] (7) By providing a plurality of suction cups on the bottom surface of the adsorption plate, the suction cups can adsorb the upper surface of the bottle cap, causing the bottle cap to be adsorbed and attached to the adsorption plate, thereby forcing the bottle cap to maintain a horizontal state. This can prevent the phenomenon of the bottle cap being skewed and causing misalignment between the bottle cap and the bottle mouth, thus improving the success rate of screwing on the bottle cap.

[0023] (8) By providing an anti-slip layer on the surface of the clamping plate, the resistance between the clamping plate and the bottle cap is increased, which can prevent the bottle cap from slipping during the screwing process and make the screwing effect better.

[0024] (9) By providing a protective cover on the bottom plate, the protective cover protects the components below the installation table, prevents impurities from entering and affecting the normal operation of the device, and also makes the production environment safer.

[0030] When the first electromagnet 704 is energized, it attracts the first permanent magnet 703, driving the first permanent magnet 703, the sliding rod 702, and the fixing cover 706 to move downward, so that the bottle cap enters the inside of the fixing cover 706.

[0031] The fixing cover 706 is also provided with a first piston 7061, an adsorption plate 7062, a second spring 7063, a second piston 7064, a clamping plate 7065, and a communicating pipe 7066; the first piston 7061 is fixedly connected to the inner top wall of the fixing cover 706 by inlay, the adsorption plate 7062 is fixedly connected to the movable end of the first piston 7061, the bottom surface of the adsorption plate 7062 is provided with a plurality of suction cups 7067, and the suction cups 7067 can adsorb the upper surface of the bottle cap, so that the bottle cap is adsorbed and attached to the adsorption plate 7062, thereby forcing the bottle cap to maintain a horizontal state, which can prevent the phenomenon of the bottle cap being skewed and causing the bottle cap and the bottle mouth to be misaligned, thus improving the success rate of tightening the bottle cap.

The two ends of the communicating pipe 7066 respectively penetrate the top and the side wall of the fixing cover 706 and are fixedly communicated with the first piston 7061 and the second piston 7064.

[0032] After the bottle cap enters the inside of the fixing cover 706, the fixing cover 706 continues to move downward, and the bottle cap presses the adsorption plate 7062, so that the gas in the first piston 7061 is squeezed into the second piston 7064 through the communicating pipe 7066, thereby driving the clamping plate 7065 to move towards the middle, clamping and fixing the bottle cap, and pressing the bottle cap from the top, making the bottle cap more stable when being tightened.

[0033] A servo motor 10 is fixedly installed in the middle of the bottom plate 4. The output end of the servo motor 10 is fixedly connected to a connecting rod 11. The upper end of the connecting rod 11 is fixedly connected to the mounting bracket 701. A limiting sliding sleeve 12 is fixedly sleeved on the outer wall of the connecting rod 11. An installation table 13 is arranged above the bottom plate 4. The limiting sliding sleeve 12 penetrates through the installation table 13 and is slidably connected to the installation table 13.

[0034] An adjusting member 8 is arranged below the installation table 13. The adjusting member 8 includes a cylinder 801, an elastic telescopic rod 802, a slider 803 and a chute 804. Both the cylinder 801 and the elastic telescopic rod 802 are fixedly connected to the bottom plate 4. There are multiple groups of elastic telescopic rods 802. There are multiple sliders 803. The top of the cylinder 801 and each elastic telescopic rod 802 are fixedly connected to a slider 803. The chute 804 is fixedly connected to the bottom of the installation table 13. The slider 803 is slidably connected to the chute 804.

[0035] Start the cylinder 801 to drive the installation table 13 to slide up and down outside the limiting sliding sleeve 12, thereby driving the tightening member 9 to move up and down, and adjusting the distance between the tightening member 9 and the bottle cap fixing member 7. Therefore, the height of the tightening member 9 can be adjusted according to the height of the beverage bottle to adapt to beverage bottles of different heights, making the device more adaptable.

[0036] The tightening member 9 includes a bearing platform 901, a bearing seat 902, a rotating shaft 903, a baffle 904, a gear 905, a toothed ring 906, a second permanent magnet 907, a second electromagnet 908, a timer 909 and a speed measuring sensor 910. There are several groups of bearing platforms 901 and they are fixedly connected to the top of the installation table 13. The bearing seat 902 is fixedly connected to the top of the rotating shaft 903. A pressure sensor 911 is inlaid in the middle of the bearing seat 902. The pressure sensor 911 is controlled and connected to the second electromagnet 908 through a controller. The rotating shaft 903 penetrates through the installation table 13 and is rotatably connected to the bearing platform 901. The baffle 904 is fixedly connected to the lower end of the rotating shaft 903. The gear 905 is sleeved on the outer side of the rotating shaft 903 and is in damping sliding connection with the rotating shaft 903. The toothed ring 906 is fixedly connected to the bottom plate 4. Several gears 905 are all meshed with the toothed ring 906. The second permanent magnet 907 is sleeved on the outer side of the rotating shaft 903 and is fixedly connected to the upper end of the gear 905. The second electromagnet 908 is sleeved on the outer side of the rotating shaft 903 and is fixedly connected to the bottom of the installation table 13. The timer 909 and the speed measuring sensor 910 are both arranged on the installation table 13. The timer 909 and the speed measuring sensor 910 are both controlled and connected to the second electromagnet 908 through a controller.

[0037] The servo motor 10 operates to drive the mounting table 13 and the connecting rod 11 to rotate, thereby driving the fixed cover 706 on the mounting frame 701 and the bearing table 901 on the mounting table 13 to rotate. In this way, the beverage bottle and the bottle cap can revolve around the central axis of the mounting table 13. When the fixed cover 706 descends to press the bottle cap tightly, the pressure sensor 911 on the bearing seat 902 detects an increase in pressure. When the pressure reaches the threshold value, the electromagnet two 908 is activated through the controller. At this time, the magnetic poles of the side of the electromagnet two 908 and the permanent magnet two 907 that are close to each other are the same, and the electromagnet two 908 repels the permanent magnet two 907, driving the gear 905 to move downward to engage with the gear ring 906. At this time, during the revolution of the gear 905, it can also rotate around the central axis of the gear 905, thereby driving the bearing table 901 and the beverage bottle thereon to rotate, causing relative rotation between the beverage bottle and the bottle cap, and thus screwing the beverage bottle and the bottle cap tightly.

[0038] A plurality of infrared emitters 15 are provided on the orbit-changing frame 3, and two infrared receivers 16 are symmetrically provided on the protective cover 6. The infrared emitters 15 are located below the infrared receivers 16, and the infrared receivers 16 are controlledly connected to the electromagnet one 704 through the controller.

[0039] When transferring the beverage bottle from the conveyor belt 1 to the bearing table 901 for screwing, during the rotation of the orbit-changing frame 3 on one side, a plurality of infrared emitters 15 are driven to continuously pass below the infrared receivers 16. When the infrared emitter 15 rotates to directly below the infrared receiver 16, the infrared receiver 16 receives the signal and activates the electromagnet one 704, driving the fixed cover 706 to descend to clamp and fix the bottle cap. When transferring the beverage bottle after screwing from the bearing table 901 to the conveyor belt 1, during the rotation of the orbit-changing frame 3 on the other side, a plurality of infrared emitters 15 are driven to continuously pass below the infrared receivers 16. When the infrared emitter 15 rotates to directly below the infrared receiver 16, the infrared receiver 16 receives the signal and turns off the electromagnet one 704, driving the fixed cover 706 to rise to release the fixation of the bottle cap, thereby realizing the automatic loading and unloading of the beverage bottle and being able to accurately position, enabling the beverage bottle to be fixed immediately when transferred to the bearing table 901 and the fixation to be released only before leaving the bearing table 901, and being able to leave the bearing table 901 immediately after the fixation is released, thus making the screwing operation of the beverage bottle more stable.

[0040] A manipulator and a conveying device for conveying unqualified beverage bottles (this is prior art and will not be elaborated too much) are also provided on one side of the mounting table 13. When it is detected that the beverage bottle has a sealing abnormality, when the abnormal beverage bottle rotates to the position in front of the manipulator, the fixation of the beverage bottle is released, and then the manipulator takes away the abnormal beverage product and transfers it to the conveying device for conveying unqualified beverage bottles, realizing the detection and automatic separation of unqualified products.

[0041] Working principle: Before use, start the cylinder 801 to drive the mounting table 13 to slide up and down outside the limit sliding sleeve 12, thereby driving the tightening member 9 to move up and down, adjusting the distance between the tightening member 9 and the bottle cap fixing member 7, and adjusting the tightening member 9 to a suitable height according to the height of the beverage bottle to adapt to beverage bottles of different heights, making the device more adaptable; During use, the unsealed beverage bottles are conveyed on the conveyor belt 1. When passing through the limit plate 2 and the rail-changing frame 3, through the limitation of the limit plate 2 and the rotation guidance of the rail-changing frame 3, the beverage bottles on the conveyor belt 1 can be brought between the limit plate 2 and the rail-changing frame 3, changing the movement track of the beverage bottles, and finally bringing the beverage bottles onto the bearing seat 902. During the rotation of the rail-changing frame 3, it drives a plurality of infrared emitters 15 to continuously pass under the infrared receiver 16. When the infrared emitter 15 rotates directly below the infrared receiver 16, at this time the beverage bottle is driven by the rail-changing frame 3 onto the bearing seat 902. At the same time, the infrared receiver 16 receives the signal, and through the controller, the electromagnet 704 is energized. The electromagnet 704 is energized to attract the permanent magnet 703, driving the permanent magnet 703, the sliding rod 702 and the fixed cover 706 to move downward, so that the bottle cap enters the inside of the fixed cover 706. After the bottle cap enters the inside of the fixed cover 706, the fixed cover 706 continues to move downward, and the bottle cap presses the adsorption plate 7062. The suction cups 7067 on the adsorption plate 7062 can adsorb the upper surface of the bottle cap, so that the bottle cap is adsorbed and attached to the adsorption plate 7062, which can force the bottle cap to maintain a horizontal state, thus preventing the phenomenon of the bottle cap being skewed and causing the bottle cap and the bottle mouth to be misaligned, thereby improving the success rate of tightening the bottle cap. At the same time, the gas in the piston 7061 is squeezed into the inside of the piston 7064 through the connecting pipe 7066, thereby driving the clamping plate 7065 to move towards the middle, clamping and fixing the bottle cap, and pressing the bottle cap from the top, making the bottle cap more stable when being tightened; The servo motor 10 works to drive the mounting table 13 and the connecting rod 11 to rotate, thereby driving the fixed cover 706 on the mounting frame 701 and the bearing platform 901 on the mounting table 13 to rotate. In this way, the beverage bottle and the bottle cap can revolve around the central axis of the mounting table 13. When the fixed cover 706 descends to press the bottle cap, the pressure sensor 911 on the bearing seat 902 detects an increase in pressure. When the pressure reaches the threshold value, the electromagnet 908 is started through the controller. At this time, the magnetic poles of the mutually approaching sides of the electromagnet 908 and the permanent magnet 907 are the same, and the electromagnet 908 repels the permanent magnet 907, driving the gear 905 to move downward to engage with the gear ring 906. At this time, during the revolution of the gear 905, it can also rotate around the central axis of the gear 905, thereby driving the bearing platform 901 and the beverage bottle thereon to rotate, causing relative rotation between the beverage bottle and the bottle cap, and thus tightening the beverage bottle and the bottle cap; After the bottle cap is tightened, the beverage bottle can no longer rotate relative to the bottle cap. The gear 905 is subjected to resistance and stops rotating. At this time, the speed measurement sensor 910 detects that the rotation speed of the gear 905 decreases until it stops. The controller changes the magnetism of the electromagnet two 908, so that the magnetic poles of the side of the electromagnet two 908 close to the permanent magnet two 907 are opposite. The electromagnet two 908 attracts the permanent magnet two 907, driving the gear 905 to move upward and disengage from the gear ring 906, thereby reducing the resistance during rotation; When the beverage bottle is transferred from the bearing platform 901 to the conveyor belt 1 after the bottle cap is tightened, during the rotation of the other side's track-changing frame 3, it drives a plurality of infrared transmitters 15 to continuously pass under the infrared receivers 16. When the infrared transmitter 15 rotates directly below the infrared receiver 16, the infrared receiver 16 receives the signal, turns off the electromagnet one 704, drives the fixed cover 706 to rise, releases the fixation of the bottle cap, and through the limit guidance of the limit plate 2 and the track-changing frame 3, transfers the packaged beverage bottle back to the conveyor belt 1 for conveying, thus realizing the automatic loading and unloading of the beverage bottle and being able to accurately position, enabling the beverage bottle to be fixed immediately when transferred to the bearing platform 901, released only before leaving the bearing platform 901, and able to leave the bearing platform 901 immediately after being released, thereby making the tightening operation of the beverage bottle more stable; When the bottle cap is being tightened, if there is a misalignment of the teeth, then the bottle cap will get stuck and unable to rotate further after rotating one circle, resulting in an illusion that the bottle cap has been tightened. In this case, the timer 909 will detect that the rotation time of the gear 905 is too short, and then the controller will start the manipulator to pick up the beverage bottle with abnormal sealing and transfer it to the conveying device for unqualified beverage bottles. When the bottle cap has chipped teeth, the bottle cap will keep rotating and unable to stop. At this time, the timer 909 will detect that the rotation time of the gear 905 is too long, and it will also start the manipulator through the controller to pick up the beverage bottle with abnormal sealing and transfer it to the conveying device for unqualified beverage bottles, automatically separating the unqualified products.
