DETAILED DESCRIPTION

[0023] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0024] Reference Figure 1 , a defective cigar cigarette automatic rejection device comprises a Z-shaped side frame 2, a cigarette identification device 1, a linear track 7, a U-shaped carrier plate 8 and a conveyor 3, the cigarette identification device 1 is fixedly installed on the top of the Z-shaped side frame 2, the linear track 7 is installed on the Z-shaped side frame 2, the cigarette identification device 1 is fixedly installed on the top between two Z-shaped side frames 2, the linear track 7 is located below the defective cigar cigarette identification device 1, the U-shaped carrier plate 8 is suspended on the lower side wall of the cigarette identification device 1, a cigarette shifting rubber roller 9 is movably installed in the U-shaped carrier plate 8, and the conveyor 3 is arranged below the cigarette shifting rubber roller 9, the cigarette shifting rubber roller is in rolling contact with the cigarette placed on the conveyor 3, so that the cigarette placed on the conveyor 3 can roll along the conveyor 3 under the shifting of the cigarette shifting rubber roller, so that the circumferential surface of the cigarette is fully exposed to the identification field of view of the cigarette identification device 1 during the rolling process;

[0025] A traction slider 10 is slidably arranged on the linear track 7, and a push strip 11 is installed at the bottom of the traction slider 10. The moving direction of the push strip 11 is parallel to the axis of the cigarette. When the cigarette identification device 1 detects a defective cigarette, the motor at the end of the linear track 7 drives the traction slider 10 to move, and the traction slider 10 drives the push strip 11 to push out the defective cigarette and remove it.

[0026] Reference Figure 2 The U-shaped carrier plate 8 is connected to the cigarette identification device 1 above through the L-shaped plate 5. The cigarette identification device 1 adopts the existing technology and will not be described in detail here.

[0027] A cylinder 6 is installed on the L-shaped plate 5, and the push rod end of the cylinder is fixedly connected to the top of the U-shaped carrier plate 8. When pushed by the cylinder 6, the push rod of the cylinder can be raised and lowered in a direction perpendicular to the conveyor 3, thereby adjusting the distance between the U-shaped carrier plate 8 and the cigarettes on the conveyor 3, and can adapt to cigars of different sizes, thereby effectively moving various types of cigars.

[0028] There are two L-shaped plates 5, and the top ends of the two L-shaped plates 5 are symmetrically installed on the lower end wall of the cigarette identification device 1. The top ends of the L-shaped plates 5 are welded to the lower end wall of the cigarette identification device 1, and the welding position is close to the side wall of the cigarette identification device 1.

[0029] Cigarette moving rubber rollers 9 are rotatably installed in the grooves on the end faces of both ends of the U-shaped carrier plate 8. The axial direction of the cigarette moving rubber rollers 9 is parallel to the axis of the cigarette. The shaft end on one side of each cigarette moving rubber roller 9 is connected to the motor 13. Two cigarette moving rubber rollers are set to provide sufficient moving force for the cigarettes below. The cigarette moving rubber rollers are made of rubber material to have flexible contact with the cigarettes and will not damage the surface of the cigarettes.

[0030] The Z-shaped side frame 2 is fixedly installed on the bottom plate 4, and the bottom plate 4 plays a supporting role for the device. The conveyor 3 is installed on the top of the bottom plate 4, and two export slide frames 12 are symmetrically installed on both sides of the top of the conveyor 3. The push strip 11 and the two export slide frames 12 are located on the same vertical plane, and the slide frame is set with an inclination angle on the vertical plane. After the push strip 11 pushes out the cigarette, the cigarette can roll down along the slide frame and a distance is set between the bottom end face of the push strip 11 and the conveyor belt surface on the conveyor 3.

[0031] Two circular grooves are symmetrically formed on one side wall of the U-shaped carrier plate 8 , and the motor 13 is fixedly installed in the circular grooves, which provide installation space for the motor 13 .

[0032] Reference Figure 3 A rectangular hole 802 is provided on the top surface of the U-shaped carrier plate 8, and the rectangular hole 802 is located directly below the recognition and detection portion of the cigarette recognition device 1. The setting of the rectangular hole avoids blocking the field of view of the cigarette recognition device 1, and ensures that the cigarette recognition device can identify cigarette defects in the rectangular groove.

[0033] A strip groove 801 is provided on the bottom surface of the U-shaped carrier plate 8, and the cigarette moving rubber roller 9 is arranged in the strip groove 801, wherein the cross-section of the strip groove 801 is a rectangular groove, and the width of the strip groove 801 is larger than the diameter of the moving rubber roller, ensuring that the moving rubber roller can roll in the strip groove 801.

[0034] The cigarette identification device 1 is implemented by existing equipment, such as a strain gauge defect identification device based on machine vision with patent number CN202122641561.8. The equipment disclosed in the device is used to complete the identification of defective parts of the cigarette. The camera mounting bracket, AB-axis camera adjustment mechanism and shooting camera of the device are used. The cigarette identification device 1 is fixedly installed on the top between the two Z-shaped side frames 2 through the camera mounting bracket, and the shooting camera is connected to the AB-axis camera adjustment mechanism under the camera mounting bracket, and the shooting camera is used to identify the cigarette.

[0035] The working principle is as follows:

[0036] The conveyor 3 moves the cigars distributed at equal intervals to the bottom of the cigar defective cigarette identification device 1 in turn and identifies and detects whether the cigarettes are defective one by one. At the same time, the configured cigarette moving rubber roller is driven by the motor 13 to rotate and drive the soft-contact cigarettes forward to ensure that the cigarettes are in a rolling state in the defect identification area, avoid blind spots in defect identification, and improve the comprehensiveness of cigarette defect identification. The linear motor drives the pushing strip 11 connected to the traction slider 10 to move from one end to the other, and pushes the defective cigarettes to move to the output slide frame 12 for discharge, which has the structural function of automatically removing defective cigarettes.

[0037] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
