Abstract
Description
Technical Field
[0001] This utility model relates to the field of labeling machine technology, and in particular to a real-time printing side labeling machine. Background Technology
[0002] In logistics transportation or product packaging, it is often necessary to label the cardboard boxes used for packaging. Depending on the needs, labeling can be divided into front labeling and side labeling. Front labeling is to apply the label to the top of the cardboard box, while side labeling is to apply the label to any one of the four sides of the cardboard box. Among these methods, front labeling is more commonly used and is a more established practice.
[0003] Existing side labeling equipment can generally only label cartons of the same size. When there are cartons of different sizes on the labeling line, it is easy to label them crookedly or incorrectly. Therefore, its adaptability and compatibility are poor.
[0004] When boxes enter the labeling line, their orientation may be crooked, and this orientation may also change during transport on the line. Therefore, the orientation of the boxes needs to be corrected before labeling to reduce the risk of incorrect or crooked labeling. Since labeling machines often need to operate at high intensity 24 hours a day, improving the ease of maintenance and reducing maintenance costs are also very important.
[0005] Therefore, there is an urgent need for a real-time printing side labeling machine that can solve one or more of the above problems. Utility Model Content
[0006] To address one or more problems existing in the prior art, this utility model provides a real-time printing side labeling machine. The technical solution adopted by this utility model to solve the above problems is as follows: the side labeling machine is equipped with a frame, and the frame is fitted with a roller feeding assembly, a positioning assembly, and a clamping assembly. The roller feeding assembly is used to transport the material to be labeled.
[0007] The positioning component is located at the rear end of the roller feeding component, and the positioning component limits and blocks the material by means of a positioning baffle.
[0008] The clamping assembly is provided with a clamping baffle, and the frame is provided with a second baffle. The second baffle is provided with an opening, which is close to the rear end of the roller feeding assembly. The second baffle is located on the left or right side of the roller feeding assembly. The second baffle is arranged opposite to the clamping baffle. The clamping baffle cooperates with the second baffle to clamp or release the material.
[0009] A marking machine and a labeling assembly are provided on the side of the second baffle away from the clamping baffle. The marking machine outputs labels to the labeling assembly, and the labeling assembly extends from the opening and affixes the labels to the material.
[0010] The second baffle is equipped with a first photoelectric sensor, a second photoelectric sensor, a third photoelectric sensor and a fourth photoelectric sensor. The first photoelectric sensor is used to detect the material at the front end of the roller feeding assembly, the second photoelectric sensor is used to detect the material approaching the positioning assembly, and the third and fourth photoelectric sensors are located below the opening and are used to detect whether the material is clamped in place.
[0011] In some embodiments, the positioning baffle is slidably mounted on a first guide rail, and a first linear drive device drives the positioning baffle to move up and down.
[0012] Furthermore, the clamping baffle is slidably mounted on the second guide rail, the clamping baffle is located on the upper side of the roller feeding assembly, the clamping baffle passes through the roller feeding assembly and is connected to the second guide rail, and the second linear drive device drives the clamping baffle to move closer to or away from the second baffle.
[0013] Furthermore, the first linear drive device and the second linear drive device are electric lead screws.
[0014] In some embodiments, the roller feeding assembly includes a roller, a drive motor, and a transmission mechanism. A plurality of rollers are arranged in parallel and spaced apart. The drive motor drives the rollers to rotate through the transmission mechanism, which is a belt drive mechanism or a chain drive mechanism.
[0015] In some embodiments, the first photoelectric sensor and the second photoelectric sensor emit light toward the side of the material facing the second baffle.
[0016] In some embodiments, the third photoelectric sensor and the fourth photoelectric sensor are located below the roller of the roller feeding assembly, and the third photoelectric sensor and the fourth photoelectric sensor emit a set of parallel light rays, which pass through the roller feeding assembly and illuminate the material.
[0017] Furthermore, the set of parallel rays is tilted toward the rear end of the roller feeding assembly and obliquely illuminates the material.
[0018] In some embodiments, the labeling assembly is provided with a labeling front panel, which is mounted on a third guide rail. The third linear drive device drives the labeling front panel to extend or retract from the opening, and the marking machine outputs a label to the labeling front panel.
[0019] Furthermore, the labeling front panel is equipped with a vacuum label suction head, which is used to absorb the labels output by the labeling machine. The labeling front panel is provided with a buffer mechanism, which is used to absorb the impact force generated by the labeling front panel.
[0020] The technical effects achieved by this utility model are: to achieve highly efficient and adaptable side labeling, with good compatibility with boxes of different sizes. Specifically, a positioning component is used to block and align the box before labeling, a clamping component is used to clamp and limit the box and perform a second correction before labeling, a first photoelectric sensor is used to determine if a box to be labeled has entered, a second photoelectric sensor is used to determine if the box has moved to the labeling position, and a third and fourth photoelectric sensors are used to determine if the box is clamped in place (if the box is clamped in place, any misalignment will be corrected), ultimately achieving accurate labeling of the box.
[0021] The system achieves compatibility with boxes of different sizes by using positioning and clamping components, ensuring that boxes of different sizes can be corrected and moved into place. The third and fourth photoelectric sensors enable clamping detection of boxes of different sizes. Compared with existing vision inspection solutions, the system is lower in cost and simpler to maintain. Attached Figure Description

[0032] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0033] This utility model discloses a real-time printing side labeling machine, combined with... Figure 1 As shown, the side labeling machine is equipped with a frame 1, and the frame 1 is equipped with a roller feeding assembly 2, a positioning assembly 3 and a clamping assembly 4. The roller feeding assembly 2 is used to transport the material to be labeled.
[0034] Combination Figure 4 , Figure 5 As shown, the positioning component 3 is located at the rear end of the roller feeding component 2, and the positioning component 3 limits and blocks the material by means of the positioning baffle 30.
[0035] Combination Figure 4 , Figure 5 As shown, the clamping assembly 4 is provided with a clamping baffle 40, the frame 1 is provided with a second baffle 5, the second baffle 5 is provided with an opening 50, the opening 50 is close to the rear end of the roller feeding assembly 2, the second baffle 5 is located on the left or right side of the roller feeding assembly 2, the second baffle 5 is arranged opposite to the clamping baffle 40, the clamping baffle 40 cooperates with the second baffle 5 to clamp or release the material, and the clamping baffle 40 is arranged parallel to the second baffle 5;
[0036] Combination Figure 1 , Figure 7 As shown, a marking machine 6 and a labeling assembly 7 are provided on the side of the second baffle 5 away from the clamping baffle 40. The marking machine 6 outputs labels to the labeling assembly 7, and the labeling assembly 7 extends out from the opening 50 and sticks the labels onto the material.
[0037] Combination Figure 3 As shown, the second baffle 5 is equipped with a first photoelectric sensor 51, a second photoelectric sensor 52, a third photoelectric sensor 53 and a fourth photoelectric sensor 54. The first photoelectric sensor 51 is used to detect the material at the front end of the roller feeding assembly 2, the second photoelectric sensor 52 is used to detect the material approaching the positioning assembly 3, and the third photoelectric sensor 53 and the fourth photoelectric sensor 54 are located below the opening 50 and are used to detect whether the material is clamped in place.
[0038] The main controller of the side labeling machine can be a PLC or a PC. The main controller is electrically connected to the marking machine 6, the labeling component 7, the roller feeding component 2, the positioning component 3, the clamping component 4, the first photoelectric sensor 51, the second photoelectric sensor 52, the third photoelectric sensor 53 and the fourth photoelectric sensor 54, thereby realizing the control of the operation of the entire equipment.
[0039] It should be noted that the marking machine 6 and the labeling assembly 7 are commonly used devices in the field, for example, in combination with Figure 7 , Figure 8 As shown, the labeling assembly 7 is equipped with a labeling front panel 70, which is mounted on a third guide rail 71. The third linear drive device 72 (electric screw or cylinder drive module) drives the labeling front panel 70 to extend or retract from the opening 50. The marking machine 6 outputs labels to the labeling front panel 70. The labeling front panel 70 is equipped with a vacuum label suction head, which is used to absorb the labels output by the marking machine 6. The labeling front panel 70 is also equipped with a buffer mechanism, which is used to absorb the impact force generated by the labeling front panel 70. The labeling action performed by the marking machine 6 and the labeling assembly 7 is a conventional side labeling action, therefore, it will not be described in detail here.
[0040] Specifically, in combination Figure 2 As shown, the positioning baffle 30 is slidably mounted on the first guide rail 31, and the first linear drive device 32 drives the positioning baffle 30 to move up and down; combined with Figure 4 , Figure 5 As shown, the clamping baffle 40 is slidably mounted on the second guide rail 41. The clamping baffle 40 is located on the upper side of the roller feeding assembly 2. The clamping baffle 40 passes through the roller feeding assembly 2 and is connected to the second guide rail 41. The second linear drive device 42 drives the clamping baffle 40 to move closer to or away from the second baffle 5. The first linear drive device 32 and the second linear drive device 42 are electric lead screws. The frame 1 is provided with a first baffle 10 for limiting the clamping baffle 40.
[0041] Specifically, in combination Figure 5 , Figure 6 As shown, the roller feeding assembly 2 includes rollers 20, a drive motor 21, and a transmission mechanism 210. Several rollers 20 are arranged in parallel at intervals. The drive motor 21 drives the rollers 20 to rotate through the transmission mechanism 210. The transmission mechanism 210 is a belt drive mechanism or a chain drive mechanism.
[0042] Specifically, in combination Figure 3 As shown, the second photoelectric sensor 52 is disposed below the opening 50, and a buffer gap is provided between the opening 50 and the positioning baffle 30. The first photoelectric sensor 51 and the second photoelectric sensor 52 emit light towards the side of the material facing the second baffle 5 to determine the position of the material on the roller feeding assembly 2. The third photoelectric sensor 53 and the fourth photoelectric sensor 54 are located below the roller 20 of the roller feeding assembly 2. The third photoelectric sensor 53 and the fourth photoelectric sensor 54 are arranged parallel to each other on the side of the second baffle 5 facing the material. The third photoelectric sensor 53 and the fourth photoelectric sensor 54 emit a set of parallel light rays 8, which pass through the roller feeding assembly 2 and illuminate the material. When both the third photoelectric sensor 53 and the fourth photoelectric sensor 54 report that the material has been illuminated, it is determined that the material is clamped in place.
[0043] Combination Figure 3 As shown, to further improve compatibility with boxes of different sizes, the emitting ends of the third photoelectric sensor 53 and the fourth photoelectric sensor 54 are tilted toward the rear end of the roller feeding assembly 2, and the set of parallel light rays 8 are tilted toward the rear end of the roller feeding assembly 2 and tilted onto the material.
[0044] The aforementioned tilted illumination method, compared to the illumination method perpendicular to the material surface, can illuminate small boxes (both large and small boxes are close to the positioning component 3) that are far from the locations of the third and fourth photoelectric sensors, and can also illuminate large boxes located directly above them, thus achieving the purpose of compatible detection of both large and small boxes. Accordingly, multiple photoelectric sensors with the same purpose as the third and fourth photoelectric sensors can also be provided to improve the detection range.
[0045] During use, the material enters from the front end of the roller feeding assembly 2. At this time, the first photoelectric sensor 51 will be triggered, and the main controller will control the positioning assembly 3 to raise the positioning baffle 30. When the material is transported to the second photoelectric sensor 52, the second photoelectric sensor 52 will be triggered. At this time, the main controller will control the roller feeding assembly 2 to decelerate, and the material will decelerate and collide with the positioning baffle 30. At this time, under the action of the positioning baffle 30, the obliquely entering material will gradually turn to a straight position. After a preset time period, the roller feeding assembly 2 will completely stop rotating its roller 20. At this time, the clamping assembly 4 will drive its clamping baffle 40 to perform a clamping action on the material. The clamping baffle 40 will push the material closer to the second positioning baffle 30. During clamping, oblique materials are straightened by the clamping baffle 40 and the second baffle 5. When the third photoelectric sensor 53 and the fourth photoelectric sensor 54 detect the material, the main controller determines that the clamping component 4 has completed the straightening of the material, and then starts the labeling component 7. The labeling component 7 pastes the label output by the marking machine 6 onto the side of the material. After the labeling is completed, the main controller controls the positioning baffle 30 to descend and reset (the positioning baffle 30 can also descend and reset when the labeling component 7 is started), and the clamping baffle 40 to retract and reset. Then the main controller controls the roller feeding component 2 to start and feed out the labeled material and input the material to be labeled, completing a single material labeling. The material is a box.
[0046] In summary, this application achieves highly efficient and adaptable side labeling with good compatibility for boxes of different sizes. Specifically, a positioning component is used to block and align the box before labeling, a clamping component is used to clamp and limit the box and perform further alignment before labeling, a first photoelectric sensor is used to determine if a box to be labeled has entered, a second photoelectric sensor is used to determine if the box has moved to the labeling position, and third and fourth photoelectric sensors are used to determine if the box is clamped in place (if the box is clamped in place, any misalignment will be corrected), ultimately achieving accurate labeling of the box.
[0047] The system achieves compatibility with boxes of different sizes by using positioning and clamping components, ensuring that boxes of different sizes can be corrected and moved into place. The third and fourth photoelectric sensors enable clamping detection of boxes of different sizes. Compared with existing vision inspection solutions, the system is lower in cost and simpler to maintain.
