DETAILED DESCRIPTION

[0025] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0028] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0029] The utility model provides a coding device for box cover and strip cover, which includes: a correction module 1, a detection and coding module 2 and a terminal conveying module 3. The box body is generally used to make cigarette boxes, and the box made of strip cover is used to hold multiple cigarette boxes;

[0030] The correction module 1 includes a correction belt 11, a correction guardrail 12 and a correction pressure block 13. Correction guardrails 12 are provided on both sides of the correction belt 11. The correction pressure block 13 is provided above the correction belt 11. There is a gap between the correction pressure block 13 and the correction belt 11. The correction guardrail 12 includes a straight segment 121 and an oblique segment 122 connected to each other. The straight segment 121 is parallel to the movement direction of the correction belt 11. The distance between the two straight segments 121 is equal to the width of the box skin and the strip skin. The box skin and the strip skin can move on the correction belt 11 and move to between the straight segments 121 of the two correction guardrails 12 under the guidance of the oblique segment 122 on the correction guardrail 12. The detection and coding module 2 includes a detection belt 21, a detection camera 22 and a nozzle 23. The detection belt 21 is provided at one end of the correction belt 11. The detection camera 22 and the nozzle 23 are both provided above the detection belt 21. The terminal conveying module 3 includes a terminal conveying belt 31 and an elastic pressure strip 32. The terminal conveying belt 31 is arranged at one end of the detection belt 21. The elastic pressure strip 32 is arranged above the terminal conveying belt 31 and can abut against the terminal conveying belt 31. The elastic pressure strip 32 is used to press the box cover and strip cover onto the terminal conveying belt 31, making it easier for the terminal conveying belt 31 to transport the box cover and strip cover. The box cover and strip cover will not be affected by external forces and will not slip off the belt.

[0031] The present invention corrects the posture of the box skin or strip skin by using the correction guardrail 12 before the box skin or strip skin moves to the nozzle 23, so that the posture of the box skin or strip skin will not be offset when the nozzle 23 is coding the box skin or strip skin, thereby avoiding the occurrence of crooked codes. In addition, the present application also provides a correction pressure block 13 on the correction belt 11. By adjusting the size of the gap between the correction pressure block 13 and the correction belt 11, it is possible to prevent multiple box skins or strip skins from being superimposed together, so that each box skin or strip skin can be coded.

[0032] Furthermore, the detection and coding module 2 also includes a negative pressure component, which is arranged below the detection belt 21. A plurality of negative pressure holes 211 are arranged in an array on the detection belt 21. The negative pressure component can absorb objects on the detection belt 21 through the negative pressure holes 211. When the box skin and strip skin move from the correction belt 11 to the detection belt 21, the box skin and strip skin can be adsorbed on the detection belt 21 under the action of the negative pressure at the negative pressure hole 211, thereby avoiding the phenomenon of slippage when the nozzle 23 is coding the box skin and strip skin. In addition, the box skin and strip skin are adsorbed in the form of negative pressure, which ensures that when the box skin and strip skin move with the detection belt 21, since the negative pressure component is located below the detection belt 21, the negative pressure component will not interfere with the coding work of the nozzle 23 on the box skin and strip skin.

[0033] Furthermore, the inspection camera 22 includes a first inspection camera 221 and a second inspection camera 222, and the nozzle 23 is located between the first inspection camera 221 and the second inspection camera 222. The first inspection camera 221 is set close to the correction belt 11, and the second inspection camera 222 is set close to the end conveyor belt 31. When the box skin and strip skin move along with the inspection belt 21, they first pass through the first inspection camera 221. The first inspection camera 221 is used to detect whether the box skin or strip skin below is a single box skin or strip skin. Then the nozzle 23 codes the box skin or strip skin according to the detection result of the first inspection camera 221. Finally, the second inspection camera 222 determines whether the coding content on the box skin or strip skin is correct.

[0034] In addition, a transverse support rod 24 is provided above the detection belt 21. The length direction of the transverse support rod 24 is perpendicular to the movement direction of the detection belt 21. A slider 25 is slidably provided on the transverse support rod 24. The slider 25 can move along the direction of the transverse support rod 24. A slide plate 26 is slidably provided on the slider 25. The slide plate 26 can move in a vertical direction on the slider 25. The nozzle 23 is installed on the slide plate 26.

[0035] Finally, the coding of the box skin and the strip skin also includes a rejection module 4. The rejection module 4 includes an air nozzle 41 arranged at the end conveyor belt 31, and the air nozzle 41 can blow the material on the end conveyor belt 31. When the second detection camera 222 detects that the coding content is incorrect, the corresponding box skin and the strip skin move from the detection belt 21 to the end conveyor belt 31, and the corresponding air nozzle 41 can blow the box skin and the strip skin off from the end conveyor belt 31. The end conveyor belt 31 includes a first conveyor belt 311 and a second conveyor belt 312. One end of the first conveyor belt 311 is arranged close to the deviation correction belt 11, and the other end of the first conveyor belt 311 is arranged close to one end of the second conveyor belt 312. The air nozzle 41 is located above the connection between the first conveyor belt 311 and the second conveyor belt 312.

[0036] It should be understood that the above description of the specific embodiments of the present invention is merely for the purpose of illustrating the technical approach and features of the present invention. Its purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. However, the present invention is not limited to the above-described specific embodiments. Any changes or modifications made within the scope of the claims of the present invention shall be included within the scope of protection of the present invention.
