Description

Technical Field

[0001] This utility model relates to the technical field of cigarette conveying equipment, and in particular to a cigarette posture correction and positioning device for a cigarette conveying line. Background Technology

[0002] In the process of sorting and packaging cigarette cartons, horizontal sorting machines are generally used. During sorting, due to differences in cigarette weight, size, and surface smoothness, cigarette cartons are prone to tilting when transported on light belt conveyors.

[0003] The existing conveyor line lacks the function to prevent the cigarette packs from tilting. If the cigarette packs are tilted during the conveying process, it will affect the processing of the next process. It is necessary to set up a special station to manually straighten the tilted cigarette packs, especially for irregularly shaped cigarette packs and cigarette packs of different sizes. This increases labor costs, is time-consuming and labor-intensive, and also reduces sorting speed and affects sorting efficiency.

[0004] Therefore, there is an urgent need for a cigarette posture correction and positioning device for cigarette conveying lines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cigarette posture correction and positioning device for a cigarette conveyor line, which can not only achieve precise positioning of cigarettes, but also efficiently correct cigarette posture deviations. Furthermore, it eliminates the need for manual straightening of cigarettes, saving time and effort, and does not affect sorting speed and efficiency.

[0006] To address the aforementioned problems in the existing technology, this utility model adopts the following technical solution:

[0007] A cigarette posture correction and positioning device for a cigarette conveyor line, comprising:

[0008] Conveyor;

[0009] A positioning guide rod is disposed on one side of the conveyor;

[0010] A correction assembly, comprising a baffle and a limit switch, wherein the limit switch is disposed on the conveyor, the baffle is rotatably disposed with the push rod of the limit switch, and the baffle can be flipped relative to the limit switch to open or close the limit switch;

[0011] An air nozzle is disposed on the other side of the conveyor, and the valve of the air nozzle is electrically connected to the limit switch. The air outlet of the air nozzle faces the positioning guide rod and is used to apply a thrust to the cigarette packs conveyed by the conveyor, so that the cigarette packs can move along the extension direction of the baffle and slide against the positioning guide rod to correct the cigarette posture.

[0012] Preferably, the baffle extends along the width direction of the conveyor and is located behind the jet airflow from the jet nozzle along the conveying direction of the conveyor.

[0013] Preferably, there are multiple baffles, which are sequentially hinged together along the height direction of the conveyor.

[0014] Preferably, it also includes a fixing member, wherein the baffle has a connecting hole, and the fixing member is fixedly inserted through the connecting hole and the push rod of the limit switch.

[0015] Preferably, there are multiple connecting holes, which are spaced apart along the extending direction of the baffle.

[0016] Preferably, the positioning guide rod includes a positioning part and a guiding part. The positioning part extends along the conveying direction of the conveyor, and the guiding part is inclined relative to the positioning part.

[0017] Preferably, the system further includes a connector and an adjusting frame, one end of which is connected to the positioning guide rod, and the other end of which has an adjusting hole. The connector passes through the adjusting hole and is connected to the conveyor.

[0018] Preferably, the system also includes a guardrail, which is installed on the conveyor and located below the positioning guide rod.

[0019] Preferably, there are two guardrails, which are located on opposite sides of the conveyor.

[0020] Preferably, the system further includes a nozzle support, on which the air nozzle is mounted, and the nozzle support is rotatably mounted on the conveyor to adjust the tilt angle of the air nozzle.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model provides a cigarette posture correction and positioning device for a cigarette conveying line. A positioning guide rod is positioned on one side of the conveyor. The correction component includes a baffle and a limit switch. The limit switch is mounted on the conveyor, and the baffle and the limit switch's push rod are rotatably connected. The baffle can flip relative to the limit switch, opening or closing it. An air nozzle is positioned on the other side of the conveyor, with its valve electrically connected to the limit switch. The air outlet of the air nozzle faces the positioning guide rod. As the conveyor transports the cigarettes along the conveying path, when a cigarette touches the baffle and pushes it to flip, it causes the push rod to deflect to a preset angle, triggering the limit switch and activating the air nozzle. The airflow from the nozzle applies a pushing force towards the positioning guide rod to the cigarette, causing it to move along the extension direction of the baffle. During this movement, the baffle continuously applies guiding force to the front and upper sides of the cigarette, correcting any posture deviation. Finally, the cigarette adheres to the positioning guide rod, achieving positioning on one side. This device achieves a synergistic positioning effect, combining the airflow from the nozzle with the baffle to correct the cigarette's posture. This forms a multi-dimensional, flexible positioning and shaping mechanism, ensuring precise positioning of the cigarette packs while efficiently correcting posture deviations. This guarantees consistent cigarette pack posture during transport, providing a stable material base for subsequent sorting and packaging processes. Furthermore, it eliminates the need for manual straightening of the cigarette packs, saving time and labor without affecting sorting speed and efficiency. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figures 1-3As shown, in this embodiment, the cigarette posture correction and positioning device for the cigarette conveying line includes a conveyor 1, a positioning guide rod 2, a correction component, and an air nozzle 5. The positioning guide rod 2 is located on one side of the conveyor 1. The correction component includes a baffle 3 and a limit switch 4. The limit switch 4 is mounted on the conveyor 1. The baffle 3 and the push rod 41 of the limit switch 4 are rotatably connected. The baffle 3 can flip relative to the limit switch 4, opening or closing the limit switch 4. The air nozzle 5 is located on the other side of the conveyor 1, and its valve is electrically connected to the limit switch 4. The air outlet of the air nozzle 5 faces the positioning guide rod 2 and applies a pushing force to the cigarettes conveyed by the conveyor 1, allowing the cigarettes to move along the extension direction of the baffle 3 and slide against the positioning guide rod 2 to correct their posture.

[0040] For example, the conveyor 1 includes a conveyor frame and a conveyor belt. The conveyor belt moves on the conveyor frame and conveys cigarette packs by a drive motor and transmission components. The cigarette packs include standard cigarette packs and irregularly shaped cigarette packs according to different size specifications.

[0041] Limit switch 4 is installed directly above the conveyor belt and is electrically connected to the valve of nozzle 5. Along the vertical height of conveyor 1, baffle 3 is located between conveyor 1 and limit switch 4, and the top of baffle 3 is rotatably connected to the push rod 41 of limit switch 4 for linkage. The height and angle of baffle 3 are adapted to the shape of the cigarette pack, providing contact guidance to the front and top sides of the cigarette pack. When the cigarette pack contacts baffle 3 under the conveying drive of conveyor 1 and pushes baffle 3 to rotate, it causes the push rod 41 of limit switch 4 to deflect to a preset angle, thereby triggering the limit switch 4 to activate. Limit switch 4 sends the activation signal to nozzle 5 through the controller, and nozzle 5 starts and sprays air. It should be noted that when the cigarette pack passes through the baffle 3 until the next cigarette pack contacts the baffle 3, due to the elastic reset structure between the push rod 41 and the limit switch 4, the push rod 41 and the baffle 3 can return to their initial positions under the action of the elastic reset structure. The limit switch 4 disconnects the signal and sends the disconnect signal to the nozzle 5 through the controller. The nozzle 5 stops spraying, completing one positioning and shaping cycle.

[0042] Along the conveying direction of conveyor 1, positioning guide rods 2 and air nozzles 5 are respectively installed on the left and right sides of the baffle 3. The height of the positioning guide rods 2 matches the height of the cigarette packs, and the positioning guide rods 2 can contact one side of the cigarette packs to form a rigid limit, which can serve as a positioning reference for correcting the cigarette pack posture. The air inlet end of the air nozzle 5 is connected to a high-pressure air source, and the airflow output direction of the air outlet end of the air nozzle 5 is towards the positioning guide rods 2, ensuring that the airflow can form a directional thrust on the cigarette packs. The cigarette conveying method driven by blowing airflow can be compatible with various sizes and specifications of irregularly shaped cigarette packs without changing the adapter parts, which has a wide range of applications and reduces equipment costs in multi-specification production scenarios. The air nozzle 5 is equipped with a valve inside, which is used to control the opening and closing of the air nozzle 5. When the valve receives the opening and closing signal of the limit switch 4 through the controller, the air nozzle 5 can spray air or stop spraying air.

[0043] The working principle of the cigarette posture correction and positioning device on the cigarette conveyor line is as follows: First, the conveyor 1 transports the cigarettes along the conveying path. When the cigarette touches the baffle 3 and pushes the baffle 3 to flip in the front-to-back direction, it causes the push rod 41 of the limit switch 4 to deflect to a preset angle, thereby triggering the limit switch 4 to activate. The limit switch 4 sends the activation signal to the nozzle 5 through the controller, and the nozzle 5 starts and sprays air. Then, the directional airflow from the nozzle 5 applies a pushing force to the cigarette towards the positioning guide rod 2. The cigarette moves along the extension direction of the baffle 3. During the movement of the cigarette, the baffle 3 continuously applies guiding force to its front and upper sides, correcting the cigarette posture deviation. Finally, it adheres to the positioning guide rod 2, achieving positioning of one side of the cigarette. Finally, after the cigarette slides along the positioning guide rod 2 and smoothly passes the baffle 3, the baffle 3 returns to its initial position, the limit switch 4 disconnects the signal, and the nozzle 5 stops spraying air. This device achieves a synergistic positioning effect, combining the airflow from the nozzle 5 to push the cigarette packs and the baffle 3 to correct their posture. This forms a multi-dimensional, flexible positioning and shaping mechanism, ensuring precise positioning of the cigarette packs while efficiently correcting posture deviations. This guarantees consistent cigarette pack posture during transport, providing a stable material foundation for subsequent sorting and packaging processes. Furthermore, it eliminates the need for manual straightening of the cigarette packs, saving time and effort without affecting sorting speed and efficiency.

[0044] Furthermore, referring to Figures 1-3 Along the width direction of conveyor 1, the baffle 3 extends and is located behind the jet airflow of the jet nozzle 5 along the conveying direction of conveyor 1.

[0045] One end of the baffle 3 contacts the positioning guide rod 2, and the other end of the baffle 3 is spaced apart from the air nozzle 5. Along the width direction of the conveyor 1, the extension length of the baffle 3 is slightly less than the width of the conveyor 1, ensuring that all cigarettes conveyed by the conveyor 1 can be guided and positioned by the baffle 3 to the positioning guide rod 2. The airflow from the air nozzle 5 covers the front end face of the baffle 3. As the cigarettes conveyed by the conveyor 1 gradually approach and contact the front end face of the baffle 3, the directional airflow from the air nozzle 5 applies a thrust towards the positioning guide rod 2 to the cigarettes. The cigarettes move along the extension direction of the baffle 3. During the movement of the cigarettes, the baffle 3 continuously applies a guiding force to its front and upper sides to correct the cigarette posture deviation.

[0046] Furthermore, referring to Figures 1-3 There are multiple baffles 3, which are sequentially hinged together along the height direction of the conveyor 1.

[0047] Each pair of adjacent baffles 3 is hinged together, allowing the assembly of multiple baffles 3 to rotate to different degrees when pushed by cigarettes of varying thicknesses. When a thinner cigarette pushes a baffle 3, the lower baffle 3 rotates, while the upper baffle 3 remains stationary. When a thicker cigarette pushes a baffle 3, the multiple baffles 3 rotate sequentially to different degrees. This design accommodates various cigarette sizes, offering a wide range of applications and preventing cigarettes that are too thin or too thick from exceeding the baffle, thus preventing the device from failing to correct the cigarette posture.

[0048] Furthermore, referring to Figures 1-3 It also includes a fixing member 6, and the baffle 3 has a connecting hole 31. The fixing member 6 is fixedly installed in the connecting hole 31 and the push rod 41 of the limit switch 4.

[0049] The fixing component 6 is a locking bolt, and the push rod 41 has a fixing hole. The locking bolt passes through the connecting hole 31 of the baffle 3 and connects to the fixing hole of the push rod 41, so that when the baffle flips, it can drive the push rod 41 to deflect synchronously, thereby triggering the limit switch 4 to start the jet nozzle 5. It should be noted that the fixing component 6 can be removed to facilitate the replacement and maintenance of the baffle. Optionally, there are multiple connecting holes 31, which are spaced apart along the extension direction of the baffle 3. According to the conveying requirements of different conveyors 1, the push rod 41 can be connected to one of the multiple connecting holes 31, thereby changing the position of the push rod 41 on the baffle 3 to match the position of the limit switch 4 relative to the conveyor 1. If the limit switch 4 is too close to the positioning guide rod 2, the push rod 41 of the limit switch 4 is connected to the baffle near the connecting hole 31 of the positioning guide rod 2.

[0050] Furthermore, referring to Figures 1-3 The positioning guide rod 2 includes a positioning part 21 and a guiding part 22. The positioning part 21 extends along the conveying direction of the conveyor 1, and the guiding part 22 is inclined relative to the positioning part 21.

[0051] The guide section 22 has a first end and a second end. The first end is connected to the positioning section 21, and the second end is closer to one edge of the conveyor 1 than the first end. The directional airflow ejected from the nozzle 5 applies a thrust to the cigarette pack towards the positioning section 21, allowing the cigarette pack to move along the extension direction of the baffle 3 and adhere to the positioning section 21. After the cigarette pack slides along the positioning section 21 and passes smoothly through the baffle 3, the cigarette pack with its posture corrected is transported to the next process by the guiding action of the guide section 22 and the driving action of the conveyor 1.

[0052] Furthermore, referring to Figures 1-3 It also includes a connector and an adjustment frame 7. One end of the adjustment frame 7 is connected to the positioning guide rod 2, and the other end of the adjustment frame 7 is provided with an adjustment hole 71. The connector passes through the adjustment hole 71 and is connected to the conveyor 1.

[0053] The connecting piece is a locking bolt, and the adjusting hole 71 is a long, narrow, waist-shaped hole. Depending on the specifications of the cigarette packs conveyed by different conveyors, the adjusting frame 7 can be vertically adjusted along the extension direction of the adjusting hole 71, allowing the positioning guide rod 2 to move closer to or further away from the conveyor 1 in the vertical direction. After adjustment, the connecting piece passes through the adjusting hole 71 and is locked to the mounting hole of the conveyor 1, fixing the adjusting frame 7 relative to the conveyor 1 and ensuring the position of the positioning guide rod 2 meets the requirements of the cigarette pack specifications. If the cigarette pack is thin, to ensure a close fit between the cigarette pack and the positioning guide rod 2, the adjusting frame 7 needs to be moved closer to the conveyor 1 in the vertical direction, so that the distance between the positioning guide rod 2 and the conveyor belt is compatible with the thickness of the cigarette pack.

[0054] Furthermore, referring to Figures 1-3 It also includes guardrails 8, which are installed on conveyor 1 and located below positioning guide rods 2. There are two guardrails 8, located on both sides of conveyor 1, to prevent the cigarette packs conveyed by conveyor 1 from falling off from both sides of conveyor 1, thus providing a certain degree of protection.

[0055] Furthermore, referring to Figures 1-3 It also includes a nozzle bracket, on which a jet nozzle 5 is mounted, and the nozzle bracket is rotatably mounted on the conveyor 1 to adjust the tilt angle of the jet nozzle 5.

[0056] Adjusting the height of the positioning guide rod 2 and the baffle 3, and rotating the nozzle bracket, allows for adjustment of the nozzle's tilt angle. This ensures that the directional airflow from the nozzle 5 applies a thrust towards the positioning guide rod 2 to the cigarette pack, and firmly attaches the cigarette pack to the positioning guide rod 2, preventing the nozzle 5 from failing to spray the cigarette pack and thus losing its effect of correcting the cigarette's posture.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
