Description

Technical Field

[0001] This invention relates to the field of cigarette pack sampling inspection technology, specifically to an online cigarette pack sampling inspection device. Background Technology

[0002] The online cigarette pack inspection device is a high-speed, non-destructive testing device for cigarette packaging production lines. It is specifically designed for quality control during the cigarette pack production process and can replace manual labor to perform online random inspections of small packs, cartons, and other cigarette packs. It is a core supporting equipment for intelligent quality control in the tobacco industry.

[0003] Traditionally, cigarette packs are inspected manually by climbing up and taking them off the conveyor track. This not only increases the workload of the workers but also increases the possibility of accidents.

[0004] To address the aforementioned issues, we propose an online sampling inspection device for cigarette packs. Summary of the Invention

A connecting rope is fixedly installed on the top of the connecting block. A through-hole is opened at the bottom of the gas shell around the connecting rope.

[0009] Furthermore, the vertical projections of the two first electric slide rails and the second electric slide rail are set perpendicular to each other.

[0010] Furthermore, the sampling clamp includes a connecting frame, which is fixedly installed on the output part of the second electric slide rail. An electric telescopic rod is fixedly installed on the inner side of the connecting frame. The output end of the electric telescopic rod extends downward in the vertical direction and is fixedly connected to a cigarette pack clamp. Limiting rods are vertically fixed on both the left and right sides of the top of the cigarette pack clamp. A detection probe is fixedly installed on one side of the cigarette pack clamp.

[0011] Furthermore, the two limiting vertical rods are symmetrically arranged, and the upper ends of the limiting vertical rods both extend vertically upward through the connecting frame and to the outer side of the upper surface of the connecting frame, thereby limiting the vertical movement of the cigarette pack clamp. The end of the cigarette pack clamp that contacts the cigarette pack is fixedly fitted with a silicone block.

[0012] Furthermore, the guide assembly includes two vertical plates fixedly installed on the top surface of the support frame. The lower sides of the opposite sides of the two vertical plates are rotatably connected to a first concave wheel, while the inner walls of the two vertical plates are slidably installed with a second concave wheel.

[0013] Furthermore, an inlet check valve and an outlet check valve are fixedly installed on the lower part of the outer surface of the gas shell on its left and right sides, respectively. A first connecting pipe is fixedly installed on the inner wall of the inlet check valve, and a second connecting pipe is fixedly installed on the inner wall of the outlet check valve.

[0014] Furthermore, the output ends of both damping springs are fixedly connected to the bottom of the movable plate, the edges of the through hole are rounded with a rounded transition, and one end of the connecting rope is fixedly connected to the upper part of the cigarette pack clamp after passing through the guide assembly and turning.

[0015] Furthermore, the arc-shaped slide plate has an air guiding chamber inside. The inner wall of the air guiding chamber has inclined openings at positions corresponding to the inner and outer side walls of the arc-shaped slide plate. The inclined openings are inclined downwards. A frustum cylinder is fixedly installed on the top of the arc-shaped slide plate. An air intake chamber is opened inside the frustum cylinder. Suction ports are opened on both the left and right sides of the inner wall of the air intake chamber. The lower end of the first connecting pipe is fixedly connected to the outer wall of the frustum cylinder and communicates with the air intake chamber.

[0016] Furthermore, guide rods are fixedly installed on the upper side of the inner walls of the two vertical plates, and the lower ends of the two guide rods pass through the front and rear sides of the top of the second concave wheel respectively, and are fixedly connected to the lower part of the inner wall of the vertical plate. Stress springs are sleeved on the upper part of the guide rod wall.

[0017] Furthermore, the lower ends of the two stress springs respectively contact the surface of the second concave wheel, while the surface of the connecting rope passes between the first and second concave wheels.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 12This embodiment of an online cigarette pack sampling inspection device includes a cigarette pack conveying frame 1. A collection component 2 is provided on the front side of the cigarette pack conveying frame 1, and a sampling component 3 is provided on the rear side of the cigarette pack conveying frame 1. The sampling component 3 includes a support frame 301, and two first electric slide rails 302 for conveying are fixedly installed at the bottom of the support frame 301. A second electric slide rail 303 is fixedly installed at the output of the two first electric slide rails 302. The vertical projections of the two first electric slide rails 302 and the second electric slide rail 303 are perpendicular to each other. A sampling clamp 4 is fixedly installed at the output end of the second electric slide rail 303. An air shell 5 is fixedly installed on the surface of the support frame 301 at the rear side of the sampling clamp 4. An air conveying component 6 is provided on the inner wall of the air shell 5, and a guide component 7 is provided at the top of the support frame 301 for guiding.

[0038] The guide assembly 7 includes two vertical plates 701 fixedly installed on the top surface of the support frame 301. The lower sides of the opposite sides of the two vertical plates 701 are rotatably connected to a first concave wheel 702, and the inner walls of the two vertical plates 701 are slidably installed with a second concave wheel 703. The upper sides of the inner walls of the two vertical plates 701 are fixedly installed with guide rods 704. The lower ends of the two guide rods 704 pass through the front and rear sides of the top of the second concave wheel 703 respectively, and are fixedly connected to the lower part of the inner wall of the vertical plate 701. The upper part of the rod wall of the guide rod 704 is sleeved with a stress spring 705.

[0039] The lower ends of the two stress springs 705 are in contact with the surface of the second concave wheel 703, while the surface of the connecting rope 604 passes between the first concave wheel 702 and the second concave wheel 703.

[0040] The sampling clamp 4 includes a connecting frame 401, which is fixedly installed on the output part of the second electric slide rail 303. An electric telescopic rod 402 is fixedly installed on the inner side of the connecting frame 401. The output end of the electric telescopic rod 402 extends downward in the vertical direction and is fixedly connected to a cigarette pack clamp 403. Limiting rods 404 are vertically fixed on both the left and right sides of the top of the cigarette pack clamp 403. A detection probe 406 is fixedly installed on one side of the cigarette pack clamp 403. The components are arranged symmetrically, and the upper ends of the limiting vertical rods 404 all extend vertically upward through the connecting frame 401 and to the outer side of the upper surface of the connecting frame 401, thereby limiting the vertical movement of the cigarette pack clamp 403. The end of the cigarette pack clamp 403 that contacts the cigarette pack is fixedly attached to a silicone block 405. Through the flexible contact and friction characteristics of the silicone block 405, the cigarette pack is stably and firmly clamped, while avoiding damage to the printing, hot stamping layer and packaging structure of the cigarette pack surface during the clamping process.

[0041] The collection component 2 includes an arc-shaped slide plate 201 fixedly installed on the surface of the cigarette pack conveyor 1, and a detection platform 202 is provided at the lower end of the arc-shaped slide plate 201, while a meter 203 is provided on one side of the inner wall of the arc-shaped slide plate 201.

[0042] The gas delivery assembly 6 includes a movable plate 601 that is slidably installed on the inner wall of the gas shell 5. Two damping springs 602 for pulling the movable plate 601 are fixedly installed on the lower side of the inner wall of the gas shell 5. Combination ropes 8 are fixedly installed at the four corners of the top surface of the movable plate 601. A connecting block 603 is fixedly installed on the top of the four combination ropes 8. A connecting rope 604 is fixedly installed on the top of the connecting block 603. A through opening 605 is opened at the bottom of the gas shell 5 around the connecting rope 604.

[0043] Among them, an inlet check valve 606 and an outlet check valve 607 are fixedly installed on the outer surface of the gas shell 5 and on the lower part of its left and right sides, respectively. A first connecting pipe 608 is fixedly installed on the inner wall of the inlet check valve 606 and a second connecting pipe 609 is fixedly installed on the inner wall of the outlet check valve 607. The output ends of the two damping springs 602 are fixedly connected to the bottom of the movable plate 601. The edge of the hole wall of the through port 605 is rounded to eliminate the sharp corners of the hole wall. The rounded corner structure eliminates the sharp corners of the hole wall edge, avoids hard friction between the connecting rope 604 and the hole wall of the through port 605 during the process of threading and moving, and avoids surface wear caused by hard friction, thus extending the service life of the connecting rope 604. After one end of the connecting rope 604 goes around the guide component 7 and turns, it is fixedly connected to the upper part of the cigarette pack clamp 403 to ensure that the direction of the tension transmission of the connecting rope 604 is matched with the direction of the force of the cigarette pack clamp 403.

[0044] The arc-shaped slide plate 201 has an air guiding chamber 204 inside. The inner wall of the air guiding chamber 204 has inclined openings 205 corresponding to the inner and outer side walls of the arc-shaped slide plate 201. The inclined openings 205 are downwardly inclined, enabling communication between the air guiding chamber 204 and the outside of the arc-shaped slide plate 201, and adapting to the downward trajectory of the cigarette pack through the inclined structure, ensuring smooth downward movement of the cigarette pack within the arc-shaped slide plate 201. A frustum cylinder 206 is fixedly installed at the top of the arc-shaped slide plate 201. An air intake chamber 207 is opened inside the frustum cylinder 206. Suction ports 208 are opened on both the left and right sides of the inner wall of the air intake chamber 207. The lower end of the first connecting pipe 608 is connected to... The outer wall of the frustum tube 206 is fixedly connected to and communicates with the air intake chamber 207. By providing negative pressure suction to the air intake chamber 207, it forms an adsorption-assisted guiding effect on the cigarette pack entering the frustum tube 206, ensuring that the cigarette pack falls accurately into the arc-shaped slide plate 201. The lower end of the second connecting pipe 609 is fixedly connected to the rear outer wall of the arc-shaped slide plate 201 and communicates with the air guide chamber 204. It provides positive pressure blowing force to the air guide chamber 204. The blowing force is blown through the inclined port 205 to the cigarette pack sliding channel of the arc-shaped slide plate 201, providing a boost to the cigarette pack sliding down. At the same time, the airflow eliminates the static electricity between the cigarette pack and the slide wall, avoiding the problem of the cigarette pack getting stuck and blocked due to static adsorption.

[0045] The working principle of the above embodiments is as follows:

[0046] When the device is in use, in the sampling component 3, the two first electric slide rails 302 and the second electric slide rail 303 are reset to their initial positions, the electric telescopic rod 402 of the sampling clamp 4 is in the retracted state, the cigarette pack clamp 403 is in the highest limit position, in the gas supply component 6, the movable plate 601 inside the gas shell 5 is in the lower position of the inner wall of the gas shell 5 under the tension of the two damping springs 602, the connecting platform 603 is in the low position along with the movable plate 601, the connecting rope 604 is led out through the through hole 605, passes through the guide component 7 and is fixed to the upper part of the cigarette pack clamp 403, at this time the connecting rope 604 is in the slack state;

[0047] In the guide assembly 7, the second concave wheel 703, under the elastic support of two stress springs 705, is located at the lower part of the guide vertical rod 704, forming a relative clamping state with the first concave wheel 702. The connecting rope 604 is attached between the two to ensure smooth subsequent steering and tension transmission. In the collection assembly 2, the meter 203 is in standby mode, the air intake chamber 207 of the truncated cone 206 and the air guide chamber 204 of the arc-shaped slide plate 201 are in an airless state, the inclined port 205 remains connected, and the detection platform 202 is located at the corresponding position at the lower end of the arc-shaped slide plate 201, ready to receive the cigarette pack.

[0048] The cigarette packs are continuously conveyed through the cigarette pack conveyor 1. The cigarette pack conveyor 1 conveys the cigarette packs to be inspected to the front at a preset speed. When the cigarette pack is conveyed to the sampling station corresponding to the sampling component 3, the detection probe 406 triggers the sampling command and starts the sampling component 3 to start the sampling action. At this time, the collection component 2 and the gas supply component 6 enter the working state simultaneously.

[0049] The two first electric slide rails 302 of the sampling component 3 start synchronously, driving the second electric slide rail 303, whose output part is fixed together, to move along the vertical conveying direction of the cigarette pack until the sampling clamp 4 at the output end of the second electric slide rail 303 moves to directly above the cigarette pack to be sampled.

[0050] The second electric slide rail 303 is activated, which drives the sampling clamp 4 to make a slight adjustment along the direction of cigarette pack conveying, ensuring that the cigarette pack clamp 403 is precisely aligned with the clamping position of the cigarette pack to be sampled, and avoiding clamping deviation.

[0051] When the electric telescopic rod 402 of the sampling clamp 4 is activated, the output end extends downward in the vertical direction, driving the cigarette pack clamp 403 to move downward in sync. When the cigarette pack clamp 403 moves to the position of contacting the cigarette pack to be sampled, the clamp end of the cigarette pack clamp 403 closes. The silicone block 405 fixedly attached to its surface makes flexible contact with the surface of the cigarette pack. The friction characteristics of the silicone block 405 are used to achieve stable and firm clamping of the cigarette pack. At the same time, the flexible material of the silicone block 405 can effectively avoid damage to the printing layer, hot stamping layer and packaging structure of the cigarette pack surface during the clamping process, ensuring the integrity of the cigarette pack's appearance.

[0052] After the cigarette pack is clamped, the electric telescopic rod 402 retracts, causing the cigarette pack clamp 403 and the clamped cigarette pack to move upward synchronously until they return to the initial height. At the same time, the second electric slide rail 303 and the first electric slide rail 302 are activated in sequence, causing the sampling clamp 4 and the clamped cigarette pack to move directly above the testing table 202, ready to complete the cigarette pack testing.

[0053] When the connecting rope 604 is subjected to a downward pulling force, that is, during the process of the sampling clamp 4 moving down to clamp, it slides along the gap between the first concave wheel 702 and the second concave wheel 703. Due to the pulling force of the connecting rope 604, the second concave wheel 703 is subjected to an upward force. Through the squeezing force of the stress spring 705, the second concave wheel 703 is kept in close contact with the connecting rope 604 to ensure stable transmission of the pulling force. At the same time, the vertical plate 701 of the guide assembly 7 provides fixed support for the first concave wheel 702 and the second concave wheel 703 to ensure stable steering action.

[0054] Under tension, the connecting rope 604 pulls the connecting platform 603 upward through the through-hole 605. The connecting platform 603 drives the four combined ropes 8 fixed at its bottom to move upward synchronously. The combined ropes 8 pull the movable plate 601 upward. When the movable plate 601 moves upward, it stretches the two damping springs 602 fixed on the lower side of the inner wall of the air shell 5. The damping springs 602 undergo elastic deformation and generate downward tension, which buffers the upward movement of the movable plate 601 and prevents the connecting rope 604 from breaking due to excessive force caused by the excessive speed of the movable plate 601. At the same time, it ensures the smoothness of the tension transmission.

[0055] The movable plate 601 moves upward under the pull of the combined rope 8, causing the volume of the internal cavity of the gas shell 5 to change, forming a negative pressure and positive pressure difference. When the movable plate 601 moves upward, the external gas enters the gas shell 5 through the inlet check valve 606 and the first connecting pipe 608. When the movable plate 601 moves downward, that is, when the sampling clamp 4 is lifted after placing the cigarette pack, the gas in the gas shell 5 is output through the outlet check valve 607 and the second connecting pipe 609.

[0056] The first connecting pipe 608 transmits the input gas to the frustum cylinder 206. Since the lower end of the first connecting pipe 608 is fixedly connected to the outer wall of the frustum cylinder 206 and connected to the suction chamber 207, the suction gas is delivered to the suction chamber 207 to form a negative pressure suction force. The negative pressure suction force is released through the suction ports 208 on the left and right sides of the inner wall of the suction chamber 207. When the cigarette pack after the test is completed is released by the sampling clamp 4 and falls above the frustum cylinder 206, the negative pressure suction force generated by the suction port 208 forms an adsorption auxiliary guiding effect on the cigarette pack, guiding the cigarette pack to fall accurately into the arc-shaped sliding plate 201 below the frustum cylinder 206, avoiding the cigarette pack from falling off course or getting stuck.

[0057] The second connecting pipe 609 transmits the output gas to the arc-shaped slide plate 201. Since the lower end of the second connecting pipe 609 is fixedly connected to the rear outer wall of the arc-shaped slide plate 201 and communicates with the air guide cavity 204, the gas is delivered to the air guide cavity 204 and forms a positive pressure blowing force. The positive pressure blowing force is blown out through the inclined openings 205 on the inner wall of the air guide cavity 204 corresponding to the inner and outer walls of the arc-shaped slide plate 201. The inclined openings 205 are set to be inclined downward, and their inclination direction is adapted to the downward trajectory of the cigarette pack in the arc-shaped slide plate 201. The blowing force directly acts on the downward channel of the cigarette pack, providing a boost for the downward movement of the cigarette pack. At the same time, the airflow can effectively eliminate the static electricity generated between the surface of the cigarette pack and the inner wall of the arc-shaped slide plate 201, preventing the cigarette pack from being attracted to the slide wall due to static electricity, preventing the cigarette pack from getting stuck and blocked, and ensuring that the cigarette pack slides down smoothly.

[0058] Under the dual action of adsorption guidance and blowing force, the cigarette packs smoothly slide down the arc-shaped trajectory of the arc-shaped slide plate 201 and finally fall onto the detection platform 202 at the lower end of the arc-shaped slide plate 201, completing the collection of the cigarette packs. When the cigarette packs slide past one side of the inner wall of the arc-shaped slide plate 201, the meter 203 on one side of the inner wall of the arc-shaped slide plate 201 is triggered to count and automatically record the number of cigarette packs sampled, realizing the measurement statistics of the sampled cigarette packs, which is convenient for subsequent quality traceability and data statistics.

[0059] This device emphasizes innovative structure and does not elaborate too much on existing mature technologies, such as electric slide rail structure, cigarette pack conveyor 1, meter 203, detection probe 406, etc.

[0060] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
