Description

Technical Field

[0001] The invention relates to the technical field of packaging machinery, in particular to a bottle bottom marking consistency collating device. Background Art

[0002] In the automated packaging industry, bottle bottoms often require logos or features to meet market needs, regulatory requirements, industry safety, or other functional considerations. This logo needs to be designed on the bottom of the bottle, and the automatic labeling equipment production line needs to implement a consistency mechanism for this logo (that is, automatically aligning the logo to the same phase). After this process, the bottle enters the sleeve labeling or labeling process, and the label on the bottle is in the ideal relative position with the bottom logo.

[0003] For example, the patent application CN201710907886.1 includes a first camera assembly located upstream of the conveyor chain, which is used to photograph the bottles to obtain first image information of the bottles; an image processing unit, which is used to determine the orientation of the bottles based on the first image information and determine the required rotation angle of the bottles according to a predetermined direction; and a bottle rotating mechanism, which is located downstream of the conveyor chain and is used to rotate the bottles that enter the rotating mechanism. The rotating mechanism recognizes the bottles and then rotates them to a specific angle.

[0004] In the prior art of the above patent, the bottle can be driven to rotate to the required rotation angle through a rotating mechanism. However, during the rotation adjustment, the bottle is placed on a conveyor chain, and the conveyor chain is usually rough in order to maintain a large friction force for stable conveying of the bottle. Moreover, the bottle is usually in a state after filling and capping when entering the labeling process, and the bottle has a large weight. Therefore, the friction between the bottle and the conveyor chain is large when rotating, which easily leads to friction marks on the bottom. Therefore, a bottle bottom label consistency sorting device is urgently needed to solve the above problem. Summary of the Invention

[0005] The purpose of the present invention is to provide a bottle bottom marking consistency arrangement device to solve the above-mentioned deficiencies in the prior art.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a bottle bottom marking consistency arrangement device, comprising a collection and conveying mechanism, which includes a feed conveyor belt, a transition conveyor belt, and a data collection assembly located between the two conveyor belts, for conveying bottles and collecting data on the bottle bottom markings to determine the rotation angle required to adjust the bottles;

[0008] The bottle mouth clamping and rotating mechanism is mounted on the bottle body clamping and transition mechanism and is located downstream of the bottle body clamping and transition mechanism, and is used to rotate the bottle in the air to the required angle.

[0009] During the conveying process of the bottle by the collection and conveying mechanism, the position of the bottom mark of the bottle is identified by the data collection component to determine the required rotation angle of the bottle; when the data of the bottom mark is collected, the bottle body clamping and transition mechanism drives the bottle to move above the data collection component; the bottle enters the bottle mouth clamping and rotating mechanism in a state of being suspended at the bottom, and the bottle is rotated to the required angle by the bottle mouth clamping and rotating mechanism.

[0011] Preferably, the collection and conveying mechanism further includes a conveying chain plate, which is located downstream of the bottle mouth clamping and rotating mechanism and is used to receive the bottle after the rotation angle of the bottle mouth clamping and rotating mechanism is adjusted.

[0012] Preferably, the bottle body clamping and transition mechanism is located directly above the data collection component, and includes a lower bottle clamping belt component and an upper bottle clamping belt component arranged symmetrically, which are used to clamp the bottle body to drive the bottle to move above the top of the data collection component.

[0013] Preferably, the bottle body clamping and transition mechanism further includes a spline shaft, and the lower bottle clamping belt component and the upper bottle clamping belt component are传动连接 (driven and connected) by the spline shaft.

[0014] Preferably, the upper bottle clamping belt component is adjustably installed above the lower bottle clamping belt component.

[0015] Preferably, the bottle mouth clamping and rotating mechanism includes two groups of symmetrically arranged bottle mouth clamping and rotating components. The bottle mouth clamping and rotating component includes a synchronous belt, which is used to clamp the bottle mouth, and by controlling the rotation directions of the synchronous belts in the two groups of bottle mouth clamping and rotating components, the rotation adjustment of the bottle and the conveying before and after the adjustment are realized.

[0016] Preferably, the synchronous belt is integrally arranged in an "丄" shape, the front end of the synchronous belt extends into the bottle body clamping and transition mechanism, and the rear end extends onto the conveying chain plate.

[0017] Preferably, the bottle mouth clamping and rotating component further includes a receiving frame, and a receiving groove is formed on the receiving frame for clamping the neck of the bottle mouth.

[0018] Preferably, the receiving frame is located below the synchronous belt, and the receiving frame is integrally arranged along the conveying direction of the bottle by the synchronous belt.

[0019] In the above technical solution, the beneficial effects of the present invention are as follows: the bottles are conveyed to the position of the bottle mouth clamping and rotating mechanism at equal intervals by the collection and conveying mechanism; when the bottles pass through the data collection component, the bottle body is clamped and conveyed by the bottle body clamping and transition mechanism, so that the bottles can smoothly transition on the data collection component, and then the data collection component can identify the position of the bottle bottom mark to determine the required rotation angle of the bottle; the bottle enters the bottle mouth clamping and rotating mechanism with the bottom suspended in the air, and the bottle mouth is clamped by the bottle mouth clamping and rotating mechanism to achieve the required rotation angle of the bottle; the device has a wide range of applications, and the bottle bottom can be rotated and adjusted after being suspended in the air to avoid friction marks on the bottle bottom.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0041] See also Figure 1-13The embodiment of the present invention provides a technical solution: a bottle bottom mark consistency sorting device, comprising a collection and conveying mechanism 2, which includes a feed conveyor belt 23, a transition conveyor belt 24, and a data collection component located between the two conveyor belts, for conveying bottles and collecting data on the bottle bottom marks to determine the rotation angle required to adjust the bottle;

[0042] The bottle body clamping transition mechanism 1 is mounted on the data acquisition component and is used to drive the bottle to smoothly transition on the data acquisition component when collecting data on the bottle bottom mark;

[0043] The bottle mouth clamping and rotating mechanism 3 is mounted on the bottle body clamping and transition mechanism 1 and is located downstream of the bottle body clamping and transition mechanism 1, and is used to rotate the bottle to a desired angle in the air;

[0044] During the bottle conveying process, the collection and conveying mechanism 2 identifies the position of the bottle bottom mark through the data collection component and determines the required rotation angle of the bottle; when collecting data of the bottle bottom mark, the bottle body clamping transition mechanism 1 drives the bottle to move above the data collection component; the bottle enters the bottle mouth clamping and rotating mechanism 3 with the bottom suspended, and is rotated to the required angle by the bottle mouth clamping and rotating mechanism 3.

[0045] Specifically, during use, the collecting and conveying mechanism 2 conveys the bottles downstream at equal intervals under the control of the existing control system. The bottles enter the bottle body clamping and transition mechanism 1 before passing through the data collection component, and the bottle body is clamped and continuously conveyed downstream by the bottle body clamping and transition mechanism 1. At the same time, the bottles are conveyed by the bottle body clamping and transition mechanism 1 so that the bottles can smoothly transition above the data collection component. When the bottles pass through the data collection component, the data collection component identifies the position of the bottle bottom mark and transmits the collected data to the control system, which processes the collected data to determine the required rotation angle of the bottles. The bottles are conveyed by the bottle body clamping and transition mechanism 1 with the bottom suspended in the air and enter the bottle mouth clamping and rotating mechanism 3. The bottle mouth clamping and rotating mechanism 3 clamps the bottle mouth and rotates the bottle to the required angle under the control of the control system. After the rotation of the bottle is adjusted, the bottle mouth clamping and rotating mechanism 3 is controlled by the control system to convey the bottles downstream, so that the bottles with adjusted angles are moved back to the collecting and conveying mechanism 2, and the bottles are continued to be conveyed downstream.

[0046] Compared with the prior art, the present invention conveys the bottles to the bottle mouth clamping and rotating mechanism 3 at equal intervals through the collection and conveying mechanism 2. When the bottle passes through the data collection component, the bottle body is clamped and conveyed by the bottle body clamping and transition mechanism 1, so that the bottle can smoothly transition on the data collection component, and then the data collection component can identify the position of the bottle bottom mark to determine the required rotation angle of the bottle. The bottle enters the bottle mouth clamping and rotating mechanism 3 with the bottom suspended in the air, and the bottle mouth is clamped by the bottle mouth clamping and rotating mechanism 3 to achieve the required rotation angle of the bottle. The device has a wide range of applications, and the bottle bottom can be rotated and adjusted after being suspended in the air to avoid friction marks on the bottle bottom.

[0047] To ensure that the control system can stably identify the bottle position, a position recognition component can be set in each mechanism, such as a position sensor to identify the bottle position, so that the control system can accurately determine the bottle position and thus control the working status of each mechanism.

[0048] In one embodiment provided by the present invention, the feed conveyor belt 23, the data acquisition component and the transition conveyor belt 24 are arranged in sequence from front to back, and the top of the data acquisition component is not higher than the top of the feed conveyor belt 23 and the transition conveyor belt 24. Specifically, the collection and conveying mechanism 2 also includes a conveying and collection installation frame 21 and a servo motor 22. The servo motor 22 is fixedly installed on the conveying and collection installation frame 21 near the feed conveyor belt 23. The servo motor 22 is transmission-connected to the feed conveyor belt 23. The servo motor 22 can provide power for the rotation of the feed conveyor belt 23 and the transition conveyor belt 24; the data acquisition component is embedded in the conveying and collection installation frame 21, and consists of a CCD camera 25 and a ring light source 26. When the bottle moves above the data acquisition component, the ring light source 26 supplements the light source. The CCD camera 25 can take a picture of the bottle bottom mark and transmit the photo information to the control system. After the control system recognizes the position of the bottle bottom mark, it can adjust the required rotation angle of the bottle.

[0049] In one embodiment provided by the present invention, the collecting and conveying mechanism 2 further includes a conveying chain plate 27, which is located downstream of the bottle mouth clamping and rotating mechanism 3 and is used to receive the bottles after the rotation angle of the bottle mouth clamping and rotating mechanism 3 is adjusted. Specifically, the top of the conveying chain plate 27 is at the same height as the top of the transition conveying belt 24 and the feed conveying belt 23. The conveying chain plate 27 and the transition conveying belt 24 are connected to the feed conveying belt 23 through a chain sprocket, ensuring that the servo motor 22 can synchronously drive the feed conveying belt 23, the transition conveying belt 24 and the conveying chain plate 27 to rotate, thereby realizing smooth conveying of the bottles; the conveying chain plate 27 and the transition conveying belt 24 are in a disconnected state, and the distance between the two is determined by the space required for the bottle mouth clamping and rotating mechanism 3 to rotate the bottles.

[0050] In another embodiment provided by the present invention, the bottle body clamping and transition mechanism 1 is located directly above the data acquisition component, and includes a symmetrically arranged lower bottle clamping belt assembly 13 and an upper bottle clamping belt assembly 14, which are used to clamp the bottle body to drive the bottle to move on the top of the data acquisition component. Specifically, the bottle body clamping and transition mechanism 1 also includes a spacing adjustment frame 11 and a clamping mounting frame 12. The lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 are rotatably mounted on the top of the clamping mounting frame 12. The clamping mounting frame 12 is set on the spacing adjustment frame 11. The position of the clamping mounting frame 12 can be adjusted by the spacing adjustment frame 11, thereby adjusting the spacing between the two groups of lower bottle clamping belt assemblies 13 and upper bottle clamping belt assemblies 14 to achieve clamping and conveying bottles of different diameters; the bottles entering the bottle body clamping and transition mechanism 1 are processed at equal intervals and in the same direction upstream by the processing equipment in the prior art. For example, when a quadrilateral bottle comes in, the four sides are in the same direction, ensuring that the bottle can be stably clamped after entering the bottle body clamping and transition mechanism 1.

[0051] In another embodiment provided by the present invention, the bottle body clamping transition mechanism 1 also includes a spline shaft 15, and the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 are transmission-connected through the spline shaft 15. Specifically, the bottle body clamping transition mechanism 1 also includes a servo motor 16. The servo motor 16 is fixedly mounted on one end of the clamping mounting frame 12, which can drive the spline shaft 15 to rotate, thereby providing power for the rotation of the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14; the top end of the spline shaft 15 is rotatably connected to the upper bottle clamping belt assembly 14, and the spline shaft 15 is inserted into the lower bottle clamping belt assembly 13. When the upper bottle clamping belt assembly 14 moves up and down, it can drive the upper bottle clamping belt assembly 14 to move synchronously. At the same time, the spline shaft 15 can slide in the lower bottle clamping belt assembly 13 to ensure stable power transmission.

[0052] In another embodiment provided by the present invention, the upper bottle clamping belt assembly 14 is adjustably mounted above the lower bottle clamping belt assembly 13. Specifically, the bottle body clamping transition mechanism 1 further includes a bottle clamping belt adjusting screw 17, which is threadedly connected to the clamping mounting frame 12. The end of the bottle clamping belt adjusting screw 17 is rotatably connected to the upper bottle clamping belt assembly 14. Rotating the bottle clamping belt adjusting screw 17 can drive the upper bottle clamping belt assembly 14 to move up and down, so that the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 can cooperate to clamp bottles of different heights. The bottle body is held and conveyed by the upper and lower sets of bottle clamping belts, which can clamp the bottle body at multiple locations, thereby improving the stability of the bottle during conveyance. A set of bottle clamping belts is provided. Even if the width of the bottle clamping belts is widened, it is difficult for a set of bottle clamping belts to achieve effective contact with the bottle body due to the limitations of the shapes of various parts of the bottle body. The bottle body does not require a circular cross-section. Square, polygonal, and special-shaped bottles can all be clamped and conveyed by the symmetrically arranged lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14, as long as there are two regular shapes at the height of the bottle body.

[0053] It can be seen from the above embodiments that, since the bottle body is relatively soft, when the symmetrically arranged lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 clamp the bottle body, the contact position between the bottle body and the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 is easily squeezed and contracted inward, resulting in a relatively small clamping force on the bottle body, making it difficult for the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 to drive the bottle to move stably. Therefore, the following embodiments are proposed to solve the above problems.

[0054] A uniformly distributed extrusion component 18 is provided between the upper bottle clamping belt assembly 14 and the lower bottle clamping belt assembly 13. The spacing between adjacent extrusion components 18 is the same as the distance at which the bottles are evenly spaced before entering the bottle body clamping transition mechanism 1. The extrusion component 18 includes an upper connecting rod 181, a lower connecting rod 182 and an extrusion head 183 fixedly mounted on the upper connecting rod 181. The upper connecting rod 181 is fixedly connected to the upper bottle clamping belt assembly 14, and the lower connecting rod 182 is fixedly connected to the lower bottle clamping belt assembly 13. The upper connecting rod 181 and the lower connecting rod 182 are in a plug-in state. The upper connecting rod 181 and the lower connecting rod 182 can rotate synchronously with the upper bottle clamping belt assembly 14 and the lower bottle clamping belt assembly 13; the extrusion surface of the extrusion head 183 is closer to the bottle body clamping transition mechanism 1 than the extrusion surfaces of the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14. When the bottle enters the bottle body clamping transition mechanism 1, the extrusion head 183 squeezes the bottle body and applies a certain pressure on the bottle, thereby reducing the inward contraction of the bottle body at the clamping position when the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 clamp the bottle body, thereby increasing the clamping force of the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 on the bottle; the extrusion component 18 rotates with the upper bottle clamping belt assembly 14 and the lower bottle clamping belt assembly 13 to achieve auxiliary squeezing of the bottle while also limiting the position of the bottle to avoid the bottle tilting during the conveying process; the upper connecting rod 181 and the lower connecting rod 182 are plugged in and connected to ensure that when the upper bottle clamping belt assembly 14 moves up and down, the upper connecting rod 181 and the lower connecting rod 182 are always in a connected state, thereby achieving stable restriction on the position of the extrusion head 183.

[0055] In another embodiment provided by the present invention, the bottle mouth clamping and rotating mechanism 3 includes two groups of symmetrically arranged bottle mouth clamping and rotating components 34. The bottle mouth clamping and rotating component 34 includes a synchronous belt 347 for clamping the bottle mouth. By controlling the rotation direction of the synchronous belt 347 in the two groups of bottle mouth clamping and rotating components 34, the rotation adjustment of the bottle and the conveying before and after the adjustment are realized. Specifically, the bottle mouth clamping and rotating mechanism 3 further includes a vertical adjustment frame 31. A vertical slide 32 is movably installed on the vertical adjustment frame 31, and a horizontal adjustment frame 33 is provided on the vertical slide 32. The bottle mouth clamping and rotating component 34 is movably installed on the horizontal adjustment frame 33. The horizontal position of the bottle mouth clamping and rotating component 34 can be adjusted through the horizontal adjustment frame 33, and the vertical position of the vertical slide 32, the horizontal adjustment frame 33, and thus the bottle mouth clamping and rotating component 34 can be adjusted through the vertical adjustment frame 31. The bottle mouth clamping and rotating component 34 further includes an adjustment slide 341. A servo motor three 342 is fixedly installed on the top of the adjustment slide 341. A driving synchronous pulley 343 located below the adjustment slide 341 is fixedly sleeved on the output shaft of the servo motor three 342. The synchronous belt 347 is meshed and sleeved outside the driving synchronous pulley 343. The servo motor three 342 in the two groups of bottle mouth clamping and rotating components 34 is independently controlled by the control system to drive the synchronous belt 347 to rotate. The two synchronous belts 347 are driven to rotate in the same direction to rub and rotate the bottle mouth. The two synchronous belts 347 rotate in opposite directions. According to the different rotation directions, the bottle can be conveyed forward and backward. No matter what the shape of the bottle body is, its bottle mouth is circular. By clamping the bottle mouth with two symmetrically arranged synchronous belts 347 and performing independent driving, the stable rotation and conveying of the bottle can be realized. An anti-slip rubber surface is bonded to the side of the synchronous belt 347 that cooperates with the bottle mouth to ensure that the synchronous belt 347 can be in stable contact with the bottle mouth.

[0056] In another embodiment provided by the present invention, the synchronous belt 347 is integrally arranged in an "丄" shape. The front end of the synchronous belt 347 extends into the bottle body clamping and transition mechanism 1, and the rear end extends onto the conveying chain plate 27. Specifically, a positioning support plate 344 located inside the synchronous belt 347 is fixedly installed at the bottom of the adjustment slide 341. A first guide wheel 345 and a second guide wheel 346 are movably installed at the front end and the rear end of the positioning support plate 344 respectively. The shape of the synchronous belt 347 can be restricted through the first guide wheel 345 and the second guide wheel 346 to ensure that the front end of the synchronous belt 347 can partially cover the lower bottle clamping belt component 13 and the upper bottle clamping belt component 14, and the rear end can partially cover the conveying chain plate 27, so as to ensure the smooth transition of the bottle between the lower bottle clamping belt component 13, the upper bottle clamping belt component 14 and the synchronous belt 347, and between the synchronous belt 347 and the conveying chain plate 27.

[0057] As can be seen from the above embodiments, the bottle body is clamped by the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 and transported between the two sets of synchronous belts 347. The bottle mouth can be clamped between the two sets of synchronous belts 347. At this time, the bottom of the bottle is in a suspended state, and the bottle is only clamped by the two sets of synchronous belts 347 to achieve vertical positioning. There is a probability that the bottle will fall during the rotation and transportation process. Therefore, the following embodiments are proposed to solve the above problems.

[0058] In another embodiment provided by the present invention, the bottle mouth clamping and rotating assembly 34 further includes a receiving frame 348, and a receiving groove 349 is provided on the receiving frame 348 for clamping the bottle mouth neck. Specifically, a limiting ring is provided at the neck of the bottle mouth, which is located below the threaded section and is used to limit the position of the bottle cap. When the bottle mouth moves into the two sets of synchronous belts 347, the limiting ring is synchronously clamped into the receiving groove 349. The position of the limiting ring is limited by the receiving frame 348 and the receiving groove 349 to prevent the bottle from falling during rotation and transportation. In order to reduce the friction between the limiting ring and the receiving frame 348, the receiving frame 348 is selected to have a tool It is made of a material with a self-lubricating effect, preferably PTFE; since the labeling process is usually after the filling process, the bottles conveyed and rotated in the device are filled bottles. Since the bottles are heavier after filling, when the lower bottle clamping belt assembly 13 and the upper bottle clamping belt assembly 14 clamp and convey the bottles and move on the data acquisition assembly, the bottom of the bottle is suspended in the air and there is a possibility that the bottle will fall. The front end of the receiving frame 348 can be extended toward the bottle body clamping transition mechanism 1, so that after the bottle enters the bottle body clamping transition mechanism 1, the limit ring at the bottleneck position is stuck in the receiving frame 348, avoiding the bottle from falling when collecting data on the bottle bottom.

[0059] In another embodiment provided by the present invention, the receiving frame 348 is located below the synchronous belt 347, and the receiving frame 348 is arranged as a whole along the conveying direction of the bottle by the synchronous belt 347. Specifically, the receiving frame 348 is fixedly installed on the bottom of the positioning support plate 344, and the installation position of the receiving frame 348 is adapted to the synchronous belt 347 to ensure that the limiting ring at the bottleneck position can be synchronously clamped into the receiving frame 348 when the bottle mouth is clamped between the two sets of synchronous belts 347.

[0060] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
