[0046] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0047] The utility model discloses an automatic label delivery device for a product packaging production line. Figure 1-Figure 6 As shown, it includes: a rotating delivery assembly, a material discharge trough 17 and a vacuum suction rod 10;

[0048] The discharge trough 17 is used to place the labels to be delivered. The vacuum suction rod 10 is provided in plurality and arranged along the circumference of the rotating delivery component. The rotation range of the vacuum suction rod 10 covers the outlet of the discharge trough 17 and the label delivery location. The rotating delivery component is provided with a vacuum chamber 13, and the vacuum chamber 13 is connected with the vacuum suction rod 10 located between the outlet of the discharge trough 17 and the label delivery location. The rotating delivery component is arranged to rotate to attract and deliver the labels located at the outlet of the discharge trough 17 to the label delivery location.

[0049] When the vacuum suction rod 10 rotates to the outlet of the discharge trough 17 with the rotating delivery component, under the action of the vacuum chamber 13, the end of the vacuum suction rod 10 generates suction to suck the label and then rotates to the label delivery location. At this time, the suction disappears, and as the rotating disk 9 rotates, the suction rod 10 turns to the compressed air chamber. At this time, the label and the vacuum suction nozzle 11 are separated by a small amount of compressed air, and the label falls to the delivery location, completing the automatic delivery. The delivery speed can be adjusted by adjusting the number of vacuum suction rods 10 on the rotating delivery component or adjusting the rotation speed of the rotating delivery component. This device is usually installed on a product packaging assembly line. When a packaging box containing a product passes by, it automatically delivers a label or certificate. At this time, the delivery speed matches the moving speed of the packaging box.

[0050] The rotating delivery assembly includes a coaxially arranged rotating disk 9 and a fixed disk 8, wherein the fixed disk 8 is fixedly arranged, a vacuum chamber 13 is arranged on the fixed disk 8, and the vacuum suction rod 10 is fixedly arranged on the rotating disk 9, and when the vacuum suction rod 10 rotates to the vacuum chamber 13 with the rotating disk 9, negative pressure is generated in the vacuum suction rod 10. A vacuum air pipe 12 is arranged in the vacuum chamber 13, and the vacuum air pipe 12 is used to extract air to generate negative pressure.

[0051] A compressed air outlet 27 is provided on the fixed plate 8, and the compressed air outlet 27 is provided near the label delivery location; the compressed air outlet 27 is used to generate thrust at the end of the vacuum suction rod 10, so that the label can be stably delivered to the target location, avoiding electrostatic adsorption between the label and the vacuum suction rod 10 or other reasons that prevent the label from falling, resulting in label leakage.

[0052] An annular protrusion is provided on a section of the inner wall of the vacuum suction rod 10 away from the rotating delivery assembly. In a preferred embodiment, the annular protrusion forms an arc-shaped transition structure with the interior of the vacuum suction rod 10. Whether the annular protrusion can prevent the label from being sucked into the vacuum suction rod 10, the arc-shaped transition structure can stably suck labels of different sizes.

[0053] A discharge valve 19 is provided at the outlet of the discharge trough 17. When the automatic feeding device stops working, the discharge valve 19 is closed to prevent the labels from falling.

[0054] It includes a photoelectric sensor 20, which is fixedly arranged near the label placement location. When a packaging box containing a product passes through the label placement location, the photoelectric sensor 20 is triggered and starts to automatically place the label or certificate.

[0055] The working principle of the automatic label delivery device on the product packaging production line disclosed in the utility model is:

[0056] The product packaging box 23 reaches the photoelectric sensor 20 through the conveyor belt 21 (provided by the packaging line equipment). The photoelectric sensor 20 senses the product packaging box 23 and gives a signal. After receiving the signal, the variable frequency speed controller 2 controls the servo motor 3 to rotate. The rotation of the servo motor 3 causes the gear 4 on the shaft to rotate and drives the bearing gear 5 to rotate. The bearing gear 5 drives the rotating disk 9 to rotate through the linkage shaft 6. The vacuum suction rod 10 is fixed on the rotating disk 9, and the rotating disk 9 drives the vacuum suction rod 10 to rotate. The vacuum suction nozzle 11 is attached to the vacuum suction rod 10. When the rotating disk 9 rotates to the position of the vacuum chamber 13 of the fixed fixed disk 8, the vacuum suction rod 10 begins to pass through the negative pressure vacuum. When the vacuum suction rod 10 rotates to the corresponding position of the discharge valve 19, when the vacuum suction rod 10 passes through the track limit groove 24, the auxiliary bearing 26 on the vacuum suction rod 10 drives the vacuum suction nozzle 11 to suck the required material to the material discharge valve 19 through the track limit groove 24. After the vacuum suction nozzle 11 sucks up the certificate of conformity, card and other materials, and then drives the rotating disk 9 to rotate the materials to the required placement position, the end position of the vacuum chamber 13 is used to cut off the vacuum air source in the vacuum suction rod 10 on the rotating disk 9. After the vacuum air source is cut off, the turntable rotates to the compressed air outlet 27. At this time, a small amount of compressed air enters to separate the material from the vacuum suction nozzle 11. At this time, the material is placed in the required product packaging box 23 to achieve automatic placement. This cyclic action completes each material placement task.

[0057] The fixed plate 8 is of a fixed type and is fixed to the control box 1 by a fixed support frame 7. A vacuum chamber 13 is opened near the edge of the fixed plate 8. A vacuum air source interface is opened in the vacuum chamber 13. The negative pressure in the chamber can be maintained sufficient through the vacuum air pipe 12; the compressed air outlet 27 is next to the vacuum chamber 13.

[0058] The rotating disk 9 is of a rotating type and has an L-shaped vent hole. One end of the L-shaped vent hole corresponds to the vacuum chamber 13 of the fixed disk 8, and the other end corresponds to the vacuum suction rod 10. The vacuum suction rod 10 and the vacuum suction nozzle 11 are provided with vent holes, which are connected to the vent of the rotating disk 9. When the vacuum suction rod hole corresponding to the rotating disk 9 reaches the vacuum chamber 13, negative pressure vacuum is introduced into the suction rod, and the vacuum suction rod 10 corresponds to the material suction at this time.

[0059] The vacuum suction rod 10 is embedded in the rotating disk 9. The vent hole in the vacuum suction rod 10 is L-shaped. The vent hole at one end leads to the vacuum suction nozzle 11, and the vent hole at the other end leads to the fixed disk 8, corresponding to the vacuum chamber 13 of the fixed disk 8. When the position of the vacuum suction rod 10 corresponds to the fixed disk vacuum chamber 13, vacuum is introduced into the vacuum suction rod 10; when the position of the vacuum suction rod 10 corresponds to the fixed disk compressed air outlet 27, compressed air is introduced into the vacuum suction rod 10. The vacuum chamber 13 is a semi-enclosed structure, and its top is open on the contact surface with the rotating disk 9. A sealing ring is provided on the rotating disk 9 corresponding to the surface of the fixed disk 8, which is sealed with the fixed disk vacuum chamber 13. The vent hole on the vacuum suction rod 10 in the rotating disk 9 realizes the function of extracting negative pressure and delivering positive pressure when in the vacuum chamber and the compressed air chamber.

[0060] Description of the material suction process: When the vacuum suction rod 10 is rotated to the position corresponding to the discharge valve 19, and the auxiliary bearing 26 on the vacuum suction rod 10 passes through the fixed guide rail limit groove 24, the process of pushing the vacuum suction rod 10 toward the discharge valve 19 and retreating is the way to suck materials. The auxiliary bearing 26 is fixed on the vacuum suction rod 10. Its function is that when the vacuum suction rod 10 rotates to the position of the guide rail limit groove 24, the auxiliary bearing 26 drives the vacuum suction rod 10 to push forward and retreat through the guide rail limit groove 24. Pushing forward is to suck materials, and retreating is to return the vacuum suction rod 10 to its original position;

[0061] Description of the guide rail limit groove 24: The guide rail limit groove 24 is fixed on the box body 1 and is a groove-type track. When the vacuum suction rod 10 rotates to the limit groove and enters the guide rail limit groove 24 position, the auxiliary bearing 26 on the vacuum suction rod 10 enters the guide rail limit groove 24. The auxiliary bearing 26 will move according to the track designed for the guide rail limit groove 24. Its main function is to limit the activity route of the auxiliary bearing so that it can achieve the required action.

An O-ring is provided on the small tube to play the role of air pressure sealing at the connection between the large tube and the small tube; the large tube and the small tube are retractable and movable, and a spring is sleeved on the small tube. Its function is that when the vacuum suction rod 11 enters the guide rail limiting groove 24, the auxiliary bearing 26 enters the guide rail limiting groove 24, and the auxiliary bearing 26 advances the active section of the vacuum suction rod 10 to the discharge trough 17 to absorb the material according to the set track of the guide rail limiting groove 24. After the material is absorbed, the active section of the vacuum suction rod 10 returns to the original position along the guide rail limiting groove 24 under the action of the spring, and the large tube and the small tube can be prevented from moving arbitrarily under the action of the spring.

[0063] The structure of the fixed disk 8 and the rotating disk 9: The fixed disk 8 is centered on the linkage shaft 6, and the linkage shaft 6 passes through the fixed disk 8 and the rotating disk 9.
