Their accuracy and reliability directly determine the visual presentation and market acceptance of the final product. Label application and placement, the process of applying and precisely positioning the label on the cigar using specialized equipment, is crucial for ensuring the appearance and quality of cigars. Currently, this process is primarily performed by the label application component within highly automated labeling machines.

[0003] For example, utility model patent CN217731054U discloses a labeling machine comprising a labeling device comprising an XYZ three-axis linear transmission module and a label suction assembly connected to the output end of the XYZ three-axis linear transmission module. The label suction assembly is capable of applying negative pressure to absorb labels provided by a label feeding device.

[0004] However, such a device still has its limitations. The aforementioned labeling device uses an XYZ three-axis linear drive module to control the movement of the label suction component, thereby completing label suction and placement. While the XYZ three-axis module theoretically offers greater flexibility, in practice, this flexibility may be limited by overly complex motion path planning, occupying a larger operating space, and long cycle times that affect the labeling machine's operating efficiency.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The utility model provides a label suction and placement device, the specific structure of which is as follows:

[0029] like Figures 1 to 3As shown, a label suction and label placement device is used to suck eggplant labels from a label library 2 and transport the eggplant labels to an output area 3. The device includes a turntable 1, which is arranged between the label library 2 and the output area 3 and is provided with a label suction position 11 corresponding to the label library 2 and a label placement position 12 corresponding to the output area 3. A number of mold boxes 4 for sucking eggplant labels are evenly spaced on the turntable 1. When the mold box 4 is at the label suction position 11, it absorbs the label and rotates with the turntable 1 to the label placement position 12 to place the label. During the label suction and label placement operation, when the mold box 4 is at the label suction position 11, the mold box 4 absorbs the label from the label library 2. Afterwards, the mold box 4 rotates with the turntable 1 to the label placement position 12 and places the eggplant label to the output area 3. Driven by the turntable 1, the mold box 4 continues to rotate with the turntable 1 back to the label suction position 11, and the above operation is repeated. The label suction and release device provided by the present invention has a simple structure and occupies a small space. The label suction and release operation has a fast cycle time and accurate release position, thereby improving the operating quality and efficiency of the labeling machine. Furthermore, the presence of multiple mold boxes 4 means that multiple labels can be suctioned and released within a single rotation cycle of the turntable 1.

[0030] In some embodiments, the label-sucking and label-placing device further includes a negative pressure control mechanism for providing and controlling negative pressure airflow. The negative pressure control mechanism is connected to the air path of the mold box 4 to control the absorption or release of the eggplant label by the mold box 4. During use, the negative pressure control mechanism can generate a negative pressure inside the mold box 4 that can absorb the eggplant label to the mold box 4, preventing the eggplant label from falling off the mold box 4 when the turntable 1 rotates. Furthermore, when the mold box 4 rotates to the label-placing position 12, the negative pressure control mechanism can release the eggplant label from the mold box 4 by closing or reducing the negative pressure.

[0031] As a further improvement of the above embodiment, Figure 2 As shown, the mold box 4 is provided with a plurality of suction holes 41 arranged in an array. The suction holes 41 are connected to the air path of the negative pressure control mechanism. The suction holes 41 arranged in an array can ensure that when the eggplant label is adsorbed, the negative pressure on the entire surface of the eggplant label is evenly distributed.

[0032] In some embodiments, the label suction and placement device further includes a first power unit 5 and a rotating shaft 6 disposed in the middle of the turntable 1. The first power unit 5 drives the rotating shaft 6 to rotate, thereby driving the turntable 1 to rotate and achieve control over the rotation of the turntable 1. Preferably, the first power unit 5 includes a servo motor for controlling the rotation speed of the rotating shaft 6, ensuring that the turntable 1 can accurately stop at the label suction position 11 and the label placement position 12 in each cycle, thereby improving the accuracy and consistency of labeling.

[0033] In some embodiments, the mold box 4 is movable along the radial direction of the turntable 1, ensuring that the mold box 4 can more accurately fit the eggplant label during label suction and placement. In a specific embodiment, the turntable 1 is provided with a guide rail 7, the guide direction of the guide rail 7 extending along the line connecting the center of the turntable 1 and the mold box 4; the guide rail 7 is provided with a slider 8, which is connected to the mold box 4. When the slider 8 moves on the guide rail 7, it drives the mold box 4 to move smoothly along the guide direction of the guide rail 7. The label suction and placement device also includes a second power unit for driving the slider 8 to move along the guide rail 7, and the second power unit is preferably a cylinder. During use, when the mold box 4 is located at the label suction position 11, the cylinder drives the slider 8 to move the mold box 4 along the guide rail 7 away from the center of the turntable 1, so that the mold box 4 can fit more closely with the eggplant label released by the label library 2. After the label suction is completed, the cylinder drives the slider 8 to move the mold box 4 along the guide rail 7 toward the center of the turntable 1 to avoid the mold box 4 colliding with other structures during the movement with the turntable 1, until the mold box 4 rotates with the turntable 1 to the label release position 12, the cylinder pushes the slider 8 again to move the mold box 4 along the guide rail 7 away from the center of the turntable 1 to ensure that the mold box 4 releases the eggplant label to the accurate position of the output area 3.

[0034] In some embodiments, the mold box 4 is detachably connected to the turntable 1. Preferably, the mold box 4 is detachably connected to the turntable 1 by screws, which can facilitate routine maintenance and replacement of the mold box 4, and even replace different types of mold boxes 4 according to needs, thereby increasing the applicability of the equipment.

[0035] The utility model also provides a labeling machine, comprising the above label suction and placement device.
