Description

Technical Field

[0001] This invention relates to a conveying device, and more particularly to a visual inspection device for cigarette outer packaging. Background Technology

[0002] During the cigarette stick inspection process, the appearance of the cigarette stick needs to be inspected from all angles. Currently, the cigarette stick is simply transported by a conveyor belt, and cameras are set up around the conveyor belt to take fixed pictures of the cigarette stick. The angle and height between the cigarette stick and the camera are fixed, which makes it impossible to obtain multi-angle pictures of the cigarette stick and easily creates blind spots. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a visual inspection device for cigarette outer packaging to overcome the above-mentioned defects in the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A visual inspection device for cigarette packaging includes a conveyor belt, an inspection frame mounted on the conveyor belt, a visual inspection device disposed within the inspection frame, and a flipping mechanism mounted on the inspection frame. One side of the flipping mechanism is provided with a clamping and lifting mechanism and a pushing mechanism. The clamping and lifting mechanism is used to clamp and lift the cigarette stick into the pushing mechanism. The other side of the flipping mechanism is provided with a guiding mechanism. The pushing mechanism is used to push the cigarette stick into the flipping mechanism and push the cigarette stick from the flipping mechanism into the guiding mechanism. The guiding mechanism is used to guide the cigarette stick to move onto the conveyor belt.

[0006] Preferably, the pushing mechanism includes a pushing platform, a synchronous belt is provided on the detection frame, a pushing plate is provided on the synchronous belt, the synchronous belt and the pushing plate are connected by a pushing block, the synchronous belt drives the pushing plate to move, so that the pushing plate moves back and forth on the pushing platform, the pushing platform is provided on one side of the synchronous belt, and a clamping chamber is provided on the other side of the synchronous belt, so that the clamping and lifting mechanism moves up and down in the clamping chamber, so that the cigarette stick enters the clamping chamber from the conveyor belt.

[0007] Preferably, the bottom of the synchronous belt is provided with a guide roller assembly, which extends from the clamping chamber into the push platform, and guide roller assemblies are provided on both sides of the push block.

[0008] Preferably, the flipping mechanism is provided with two sets of clamping plates arranged opposite each other. When the clamping plates are arranged parallel to the frame, the cigarette stick is pushed into the clamping plates by the action of the push plate.

[0009] Preferably, the flipping mechanism is disposed on both sides of the conveyor belt, the pushing platform is disposed between the two sets of flipping mechanisms, and the pushing platform is disposed parallel to the conveying direction of the conveyor belt.

[0010] Preferably, the clamping and lifting mechanism includes a limiting plate, two sets of clamping plates, and a lifting assembly. The limiting plate is arranged perpendicular to the direction of movement of the conveyor belt, and the two sets of clamping plates are arranged opposite each other on both sides of the conveyor belt. The clamping plates move towards the direction of the conveyor belt to clamp the cigarette stick. The lifting assembly drives the clamping plates to move up and down to allow the cigarette stick to enter the pushing mechanism.

[0011] Preferably, the guiding mechanism includes an upper guiding component and a lower guiding component, with a sliding cavity provided between the upper guiding component and the lower guiding component, and the lower guiding component includes an arc-shaped guide plate and a sliding guide plate, with the arc-shaped guide plate disposed between the sliding guide plate and the flipping mechanism.

[0012] The beneficial effects of this invention are as follows: A conveyor belt is used to transport the cigarette sticks, and a detection frame is installed on the conveyor belt. A visual sensor can be installed on the detection frame, and a flipping mechanism is installed on the detection frame to achieve 360-degree detection of the cigarette sticks. A clamping and lifting mechanism and a pushing mechanism are provided on one side of the flipping mechanism. The clamping and lifting mechanism clamps the cigarette stick onto the plane of the flipping mechanism, and the pushing mechanism pushes the cigarette stick into the flipping machine, thereby achieving the flipping detection of the cigarette stick. A guiding mechanism is provided on the other side of the flipping mechanism. The detected cigarette stick slides along the guiding mechanism onto the conveyor belt, ensuring a smooth drop and preventing the cigarette stick from falling directly from the flipping mechanism and causing damage.

[0023] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0024] like Figure 1-6As shown, the present invention provides a visual inspection device for cigarette outer packaging, including a conveyor belt 1, an inspection frame 2 disposed on the conveyor belt 1, a visual inspection device disposed inside the inspection frame 2, and a flipping mechanism 3 disposed on the inspection frame 2. A clamping and lifting mechanism 4 and a pushing mechanism 5 are disposed on one side of the flipping mechanism 3. The clamping and lifting mechanism 4 is used to clamp the cigarette stick into the pushing mechanism 5. A guiding mechanism 6 is disposed on the other side of the flipping mechanism 3. The pushing mechanism 5 is used to push the cigarette stick into the flipping mechanism 3, and the pushing mechanism 5 pushes the cigarette stick from the flipping mechanism 3 into the guiding mechanism 6. The guiding mechanism 6 is used to guide the cigarette stick to move onto the conveyor belt 1. Conveyor belt 1 is used to transport cigarette sticks, and a detection frame 2 is set on conveyor belt 1. The detection frame 2 is used to install visual sensors, and a flipping mechanism 3 is set on the detection frame 2 to achieve 360-degree detection of cigarette sticks. A clamping and lifting mechanism 4 and a pushing mechanism 5 are set on one side of the flipping mechanism 3. The clamping and lifting mechanism 4 clamps the cigarette stick onto the plane of the flipping mechanism 3, and the pushing mechanism 5 pushes the cigarette stick into the flipping machine, thereby realizing the flipping detection of cigarette sticks. A guide mechanism 6 is set on the other side of the flipping mechanism 3. The detected cigarette sticks slide along the guide mechanism 6 onto the conveyor belt 1 to achieve a smooth drop of cigarette sticks and avoid the cigarette sticks falling directly from the flipping mechanism 3, which would cause the cigarette sticks to bump.

[0025] The pushing mechanism 5 includes a pushing platform 51, a synchronous belt 52 on the detection frame 2, and a pushing plate 53 on the synchronous belt 52. The synchronous belt 52 and the pushing plate 53 are connected by a pushing block. The synchronous belt 52 drives the pushing plate 53 to move, so that the pushing plate 53 moves back and forth on the pushing platform 51. The pushing platform 51 is located on one side of the synchronous belt 52, and a clamping chamber 54 is located on the other side of the synchronous belt 52, so that the clamping and lifting mechanism 4 moves up and down in the clamping chamber 54, so that the cigarette stick enters the clamping chamber 54 from the conveyor belt 1. The pushing mechanism 5 includes a pushing platform 51, a pushing plate 53 on the synchronous belt 52, a cigarette stick placed on the pushing platform 51, and the pushing plate 53 pushes the cigarette stick to move into the flipping mechanism 3. A clamping chamber 54 is located at one end of the synchronous belt 52. The clamping and lifting mechanism 4 can clamp the cigarette stick into the clamping chamber 54, and the pushing plate 53 can push the cigarette stick in the clamping chamber 54 to disengage from the clamping and lifting mechanism 4 and enter the pushing platform 51. The push plate 53 can move back and forth on the push platform 51, thereby enabling the push plate 53 to work continuously.

[0026] The bottom of the synchronous belt 52 is provided with a guide roller assembly 55, which extends from the clamping chamber 54 into the push platform 51. Guide roller assemblies 55 are provided on both sides of the push block. The guide roller assembly 55 can be used to flip the cigarette stick. The gap between the guide roller assembly 55 and the guide platform is fixed to ensure that the cigarette stick is placed in parallel. It is not possible to place the cigarette stick vertically. The guide roller assembly 55 can ensure that the cigarette stick does not tip over during the process of entering the push platform 51 from the clamping chamber 54.

[0027] The flipping mechanism 3 is equipped with two sets of clamping plates arranged opposite each other. When the clamping plates are set parallel to the frame, the cigarette stick is pushed into the clamping plates by the push plate 53. The clamping plates ensure that the cigarette stick is clamped after entering the flipping mechanism 3, and prevent the cigarette stick from falling off.

[0028] The flipping mechanism 3 is set on both sides of the conveyor belt 1, and the pushing platform 51 is set between the two sets of flipping mechanisms 3. The pushing platform 51 is set parallel to the conveying direction of the conveyor belt 1. Both sides of the conveyor belt 1 are provided with flipping mechanisms 3. By using the two sets of flipping mechanisms 3 set opposite to each other, the two ends of the cigarette stick are clamped. The pushing platform 51 is set between the two sets of flipping mechanisms 3 and is parallel to the conveying direction of the conveyor belt 1.

[0029] The clamping and lifting mechanism 4 includes a limiting plate 41, two sets of clamping plates, and a lifting assembly. The limiting plate 41 is arranged perpendicular to the movement direction of the conveyor belt 1, and the two sets of clamping plates are arranged opposite each other on both sides of the conveyor belt 1. The clamping plates move towards the conveyor belt 1 to clamp the cigarette stick. The lifting assembly drives the clamping plates to move up and down to allow the cigarette stick to enter the pushing mechanism 5. The clamping and lifting mechanism 4 includes a limiting plate 41, which is arranged perpendicular to the conveying direction of the conveyor belt 1. The limiting plate 41 is used to limit the cigarette stick, and the two sets of oppositely arranged clamping plates clamp the cigarette stick that is in contact with the limiting plate 41. After the clamping plates are driven to clamp the cigarette stick, the lifting assembly drives the clamping plates to move up and down to allow the cigarette stick to enter the pushing mechanism 5.

[0030] The guiding mechanism 6 includes an upper guiding component and a lower guiding component, with a sliding cavity 61 provided between them. The lower guiding component includes an arc-shaped guide plate 62 and a sliding guide plate 63, with the arc-shaped guide plate 62 positioned between the sliding guide plate 63 and the flipping mechanism 3. The upper and lower guiding components form a sliding cavity 61, ensuring the cigarette stick always moves within this cavity. The lower guiding component, including the arc-shaped guide plate 62 and the sliding guide plate 63, allows the cigarette stick to fall onto the arc-shaped guide plate 62. The arc-shaped guide plate 62 cushions the falling cigarette stick, preventing direct contact with the flat surface and avoiding impact. The sliding guide plate 63 guides the cigarette stick, ensuring it falls smoothly onto the conveyor belt 1.

[0031] Two sets of flipping mechanisms 3 are arranged opposite to each other, and the flipping mechanism 3 is provided with a first clamping component 31 and a top plate 33. The first clamping component 31 includes two sets of first clamping plates 311 arranged opposite to each other. The first clamping plates 311 are arranged opposite to each other on both sides of the top plate 33, and the first clamping component 31 clamps the two ends of the cigarette strip.

[0032] The flipping mechanism 3 is also provided with a second clamping component, which includes two sets of opposing second clamping plates 312. The first clamping component 31 and the second clamping component are arranged around the top plate 33. The first clamping plate 311 and the second clamping plate 312 are used to clamp the cigarette bar around the perimeter, ensuring that the cigarette bar is clamped more stably.

[0033] The driving flipping mechanism 3 is used to rotate the cigarette stick inside the first clamping assembly 31. When rotating within 0 to 90°, the first clamping assembly 31 opens with the rotation, while the second clamping assembly clamps with the rotation; when rotating within 90° to 180°, the second clamping assembly opens with the rotation, while the first clamping assembly 31 clamps with the rotation; when rotating within 180° to 270°, the first clamping assembly 31 opens with the rotation, while the second clamping assembly clamps with the rotation; when rotating within 270° to 360°, the second clamping assembly opens with the rotation, while the first clamping assembly 31 clamps with the rotation, completing the reset. Two sets of flipping mechanisms 3 are arranged opposite each other on the frame. The two sets of flipping mechanisms are arranged opposite each other to achieve stable clamping of the cigarette stick. A first clamping component 31 and a top plate 33 are arranged on the flipping mechanism 3. The top plate 33 is used to limit the cigarette stick, and the first clamping component 31 is used to clamp the cigarette stick. The first clamping component 31 includes two sets of first clamping plates 311 arranged opposite each other. The first clamping plates 311 are arranged opposite each other on both sides of the top plate 33. The first clamping plates 311 can be used to fix and clamp the cigarette stick.

[0034] Both the first clamping plate 311 and the second clamping plate 312 are provided with hinge rods, which are hinged to the top plate 33. One end of the hinge rod is provided with a clamping plate, and the other end is provided with a connecting rod. The flipping mechanism 3 is provided with a slide rail, and a sliding block 72 is slidably arranged on the slide rail. One end of the connecting rod is rotatably arranged on the sliding block 72, and the other side of the slider is connected to a cam roller. The drive wheel rotates, causing the cam roller to slide in the cam groove of the fixed cam 81, thereby causing the sliding block 72 to move, so that the clamping plate rotates. Both the first clamping plate 311 and the second clamping plate 312 are provided with hinge rods, which are hinged to the clamping plates. A connecting rod is provided at the other end of the hinge rod. By adjusting the installation position of the sliding block 72 on the slide rail, the installation angle of the connecting rod can be adjusted, thereby adjusting the angle of the hinge rod and changing the installation position of the clamping plate, thus realizing the clamping and loosening of the clamping plate.

[0035] The hinge rod includes a first hinge rod and a second hinge rod. The first hinge rod and the second hinge rod are respectively connected to the corresponding sliding blocks 72 on the first slide rail 731 and the second slide rail 732. The first slide rail 731 and the second slide rail 732 are located on the same plane. The two sets of first slide rails 731 are located on the same straight line, and the two sets of second slide rails 732 are located on the same straight line. The first slide rail 731 and the second slide rail 732 are set perpendicularly to each other. The first hinge rod and the second hinge rod are set perpendicularly to ensure that the angle between the first clamping plate 311 and the second clamping plate 312 is perpendicular. This ensures that the four sets of clamping plates are set perpendicularly, which can achieve clamping around the cigarette stick and avoid the angle between the clamping plate and the cigarette stick, which would cause clamping marks on the surface of the cigarette stick during the clamping process.

[0036] The flipping mechanism 3 includes a rotating wheel, a top plate 33 and a first clamping mechanism, all of which are mounted on the rotating wheel. A connecting rod is mounted on the rotating wheel, with one end of the connecting rod connected to the rotating wheel and the other end of the rotating wheel passing through the frame and fixedly connected to the transmission gear 82. The rotation of the rotating wheel can be achieved by using the transmission gear 82, thereby causing the flipping mechanism 3 and the cigarette strip on the flipping mechanism 3 to rotate.

[0037] A connecting gear 83 is provided on the frame, which meshes with the transmission gear 82. The two sets of connecting gears 83 are connected by a connecting shaft. A motor is provided on one side of the frame, and an output gear 84 is provided on the output end of the motor. The output gear 84 meshes with the connecting gear 83 on the corresponding side of the frame. A motor is provided on one side of the frame, and the output gear 84 meshes with the connecting gear 83. A connecting shaft is also provided on the frame. The connecting shaft is used to realize the synchronous rotation of the connecting gears 83 on both sides of the frame. At the same time, the connecting gear 83 meshes with the transmission gear to realize the synchronous rotation of the two sets of flipping mechanisms 3.

[0038] The first clamping plate 311 has a guide surface at one end, and the guide surfaces on the two sets of first clamping plates 311 are located on the same side and are arranged opposite each other. The guide surface on the first clamping plate 311 can ensure that the cigarette stick enters and exits the flipping mechanism 3 smoothly, and avoid the cigarette stick from colliding with the side of the clamping plate during the process of entering and exiting, which would cause the cigarette stick to break.

[0039] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
