Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically to a labeling device capable of automatic correction. Background Technology

[0002] Labeling equipment is a device that automates the application of labels to designated locations on products or packaging, thereby improving production efficiency and labeling quality.

[0003] Traditional labeling devices, when handling packaging box labeling, lack intelligent recognition and timely correction functions if the packaging boxes are misplaced due to human error or other reasons. This results in labels being applied haphazardly, with inconsistent and uneven placement. This not only damages the neatness and aesthetics of the product appearance and reduces the overall quality of the product, but may also affect the display and identification of product information due to improper label placement, adversely affecting subsequent sales and other processes. Therefore, a labeling device with automatic correction capability is proposed. Utility Model Content

[0004] The purpose of this invention is to address the problem that traditional labeling devices lack intelligent recognition and timely correction functions when packaging boxes are misplaced due to human error. This invention provides a labeling device that can automatically correct errors.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An automatically calibrated labeling device includes a workbench, a conveyor belt fixedly mounted on the top of the workbench, a labeling machine fixedly mounted on the top of the workbench, two sets of side rod mechanisms for assisting in the positioning and conveying of packaging boxes arranged above the conveyor belt, the two sets of side rod mechanisms being mirror-distributed, a detection mechanism for detecting the orientation of the packaging boxes arranged above the conveyor belt, two sets of clamping plate mechanisms for clamping and flipping the packaging boxes arranged above the conveyor belt, a transmission mechanism for adjusting the distance between the two sets of clamping plate mechanisms arranged above the conveyor belt, and a drive mechanism for controlling the lifting and horizontal rotation of the transmission mechanism arranged above the conveyor belt.

[0007] Furthermore, the side rod mechanism includes clamp rod 1, two clamp rod 1 are arranged above the conveyor belt, and two clamp rod 2 are arranged above the conveyor belt. A connecting frame is fixedly installed between each clamp rod 2 and clamp rod 1. A sensor 1 is embedded in the side of the two clamp rods 1 that are close to each other. A sensor 2 is fixedly installed inside each connecting frame. Bending rods are fixedly installed on both sides of the worktable. An electric push rod is fixedly installed inside each bending rod. Each electric push rod is fixedly connected to the adjacent clamp rod 2.

[0008] Furthermore, the detection mechanism includes a mounting frame, which is fixedly mounted on the conveyor belt, and a photoelectric sensor is fixedly mounted on the inner top surface of the mounting frame.

[0009] Furthermore, the clamping mechanism includes clamping plates, with two clamping plates arranged above the conveyor belt. Each clamping plate has a mounting hole on its side wall, and a ring is movably installed inside each mounting hole. A circular plate is fixedly installed inside each ring. Anti-slip pads are fixedly installed on the side of the two circular plates that are close to each other, and bending blocks are fixedly installed on the side of the two clamping plates that are far apart from each other. A servo motor for rotating the corresponding circular plate is fixedly installed inside each bending block.

[0010] Furthermore, the transmission mechanism includes a strip frame, which is arranged above the conveyor belt. A bidirectional lead screw is movably installed inside the strip frame. Moving blocks are threaded to both ends of the bidirectional lead screw. The two moving blocks are fixedly connected to two clamping plates respectively.

[0013] 1. After the packaging box is manually placed onto the conveyor belt of the workbench, it is initially guided by two sets of mirror-distributed side rod mechanisms to keep the packaging box in a straight line during transportation. When the packaging box enters the detection area of ​​the detection mechanism, the system immediately judges whether its placement is correct. If an incorrect placement is found, the drive mechanism first controls the transmission mechanism to descend to a suitable height, and then the two sets of clamping mechanisms move inward synchronously under the drive of the transmission mechanism to stably clamp the packaging box. After clamping, the drive mechanism acts again to make the clamping mechanism rotate the packaging box 90 degrees or 180 degrees. The corrected packaging box continues to be transported by the conveyor belt to the labeling machine for label affixing. Attached Figure Description

[0022] like Figure 1-3As shown, an automatic labeling device includes a workbench 1, a conveyor belt 2 fixedly mounted on the top of the workbench 1, a labeling machine 3 fixedly mounted on the top of the workbench 1, and two sets of side rod mechanisms 4 for assisting in the positioning and conveying of packaging boxes arranged above the conveyor belt 2. The two sets of side rod mechanisms 4 are mirror-distributed, as shown in the figure. Figure 1 As shown, specifically, the side rod mechanism 4 includes clamping rod 401, two clamping rods 401 are arranged above the conveyor belt 2, and two clamping rods 402 are arranged above the conveyor belt 2. A connecting frame 403 is fixedly installed between each clamping rod 402 and clamping rod 401. A sensor 404 is embedded in the side of the two clamping rods 401 that are close to each other. A sensor 405 is fixedly installed inside each connecting frame 403. Bending rods 406 are fixedly installed on both sides of the workbench 1. An electric push rod 407 is fixedly installed inside each bending rod 406. Each electric push rod 407 is fixedly connected to the adjacent clamping rod 402.

[0023] More specifically, clamp rod 401 and clamp rod 402 form a rigid frame through connecting frame 403. Electric push rod 407 extends and retracts within bending rod 406, driving clamp rod 402 to move clamp rod 401 laterally in sync, thereby adjusting the distance between the two sets of side rod mechanisms 4 in real time according to the width of the packaging box. Sensor 404 inside clamp rod 401 detects in real time whether the packaging box enters the guide area, and sensor 405 inside connecting frame 403 monitors whether the packaging box has reached the correction position.

[0024] Above the conveyor belt 2 is a detection mechanism 5 for detecting whether the packaging boxes are placed face up or face down, such as... Figure 1 As shown, specifically, the detection mechanism 5 includes a mounting frame 501, which is fixedly mounted on the conveyor belt 2, and a photoelectric sensor 502 is fixedly mounted on the inner top surface of the mounting frame 501.

[0025] More specifically, the mounting frame 501 is fixed across the conveyor belt 2, and the photoelectric sensor 502 on the top surface of the frame emits a beam of light downwards. When the intensity of the light reflected from the surface of the packaging box does not match the preset correct placement state, the photoelectric sensor 502 immediately outputs an abnormal signal. The control system judges that the packaging box is placed in the wrong direction and triggers the subsequent clamping and flipping process.

[0026] Above the conveyor belt 2 are two sets of clamping mechanisms 6 for gripping and flipping packaging boxes, such as... Figure 1-3As shown, specifically, the clamping mechanism 6 includes clamping plates 601. Two clamping plates 601 are arranged above the conveyor belt 2. Each clamping plate 601 has a mounting hole 602 on its side wall. A ring 603 is movably installed inside each mounting hole 602. A circular plate 604 is fixedly installed inside each ring 603. An anti-slip pad 605 is fixedly installed on the side of the two circular plates 604 that are close to each other. A bending block 606 is fixedly installed on the side of the two clamping plates 601 that are far from each other. A servo motor 607 for rotating the corresponding circular plate 604 is fixedly installed inside each bending block 606.

[0027] More specifically, the clamping plate 601 forms a rotatable clamping unit with the circular plate 604 through the ring 603 in the mounting hole 602, and the anti-slip pad 605 increases friction to prevent slippage; the servo motor 607 is fixed in the bending block 606, and its output shaft passes through the clamping plate 601 to directly drive the circular plate 604 to rotate; when the packaging box is clamped, the two servo motors 607 rotate synchronously in opposite directions by 180 degrees, driving the circular plate 604 and the packaging box to complete the flipping and realize the posture correction;

[0028] The other two circular plates 604 can also clamp the packaging box in a fixed state, and also facilitate the horizontal rotation of the packaging box according to the calibration requirements.

[0029] Above the conveyor belt 2 is a transmission mechanism 7 for adjusting the distance between the two sets of clamping mechanisms 6, such as... Figure 1-3 As shown, specifically, the transmission mechanism 7 includes a strip frame 701, which is arranged above the conveyor belt 2. A bidirectional lead screw 702 is movably installed inside the strip frame 701. Moving blocks 703 are threaded to both ends of the bidirectional lead screw 702. The two moving blocks 703 are fixedly connected to two clamping plates 601 respectively. A servo motor 704 for rotating the bidirectional lead screw 702 is fixedly installed at one end of the strip frame 701. An installation block 705 is fixedly installed inside the strip frame 701.

[0030] More specifically, servo motor 704 drives the bidirectional lead screw 702 inside the bar frame 701 to rotate. The reverse threads at both ends of the bidirectional lead screw 702 cause the moving blocks 703 to move synchronously towards or away from each other, thereby precisely adjusting the clamping distance between the two sets of clamping plates 601. The mounting block 705 serves as a rotation fulcrum and is connected to the drive mechanism 8 to ensure that the transmission mechanism 7 maintains overall rigidity during lifting and rotation, ensuring stable and reliable clamping action.

[0031] Above the conveyor belt 2 is a drive mechanism 8 for controlling the lifting and horizontal rotation of the transmission mechanism 7, such as... Figure 1 , 2As shown, specifically, the driving mechanism 8 includes a bending plate 801. Bending plates 801 are fixedly installed on both sides of the conveyor belt 2. An electric telescopic rod 802 is fixedly installed on the top of each bending plate 801. A crossbar 803 is fixedly installed at the output ends of the two electric telescopic rods 802. A servo motor 804 is fixedly installed at the bottom of the crossbar 803. The output end of the servo motor 804 is fixedly connected to the mounting block 705.

[0032] More specifically, the electric telescopic rod 802 on the bending plate 801 extends and retracts synchronously, driving the crossbar 803 to rise and fall as a whole, thereby adjusting the height between the clamping plate 601 and the conveyor belt 2 to accommodate packaging boxes of different sizes; the servo motor 804 is fixed at the bottom of the crossbar 803, and its output end is connected to the mounting block 705, driving the entire transmission mechanism 7 and the clamping plate mechanism 6 below it to rotate horizontally, realizing the precise flipping and correction of the packaging box.

[0033] In summary: After the packaging box is manually placed onto the conveyor belt 2 of the workbench 1, it is initially guided by two sets of mirror-distributed side rod mechanisms 4 to keep the packaging box in a straight line during transportation. When the packaging box enters the detection area of ​​the detection mechanism 5, the system immediately judges whether its placement is correct. If an incorrect placement is found, the drive mechanism 8 first controls the transmission mechanism 7 to descend to a suitable height, and then the two sets of clamping mechanisms 6 move inward synchronously under the drive of the transmission mechanism 7 to stably clamp the packaging box. After clamping, the drive mechanism 8 acts again, causing the clamping mechanism 6 to rotate the packaging box 90 degrees or 180 degrees. The corrected packaging box continues to be transported by the conveyor belt 2 to the labeling machine 3 for label affixing.
