Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, specifically to a cigarette conveying bridge device for cigarette equipment. Background Technology

[0002] In the later stages of cigarette production, specifically packaging and warehousing, cartons of cigarettes (i.e., packaged cigarette cartons) undergo sorting, palletizing, and boxing processes sequentially via multiple conveyor belts. Due to differences in the layout of equipment at each stage (such as conveyor belt height, conveying direction, and operating speed), the transition between different conveyor belts relies on a cigarette conveyor bridge device for smooth connection. Its core function is to ensure the smooth transfer of cigarettes from the upstream conveyor belt to the downstream conveyor belt.

[0003] Currently, in the cigarette production process, cigarette packs need to be flipped before being conveyed to the packaging equipment to ensure that the cigarette packs are in the correct orientation. Existing cigarette pack conveying bridge devices usually include a first conveyor belt and a second conveyor belt. However, the cigarette packs are usually flipped and placed on the second conveyor belt by manual operation, which consumes a lot of manpower and time and reduces production efficiency. Therefore, we propose a cigarette pack conveying bridge device for cigarette equipment to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-3 As shown:

[0026] A cigarette conveying bridge device for cigarette equipment includes a support frame 101;

[0027] The support frame 101 is respectively equipped with a first conveyor belt 102 and a second conveyor belt 103 that are distributed vertically.

[0028] The bridge plate 104 is installed before the first conveyor belt 102 and the second conveyor belt 103, and is designed with an inclined structure.

[0029] A rectangular cover 106 is provided on the bridge plate 104, and the bridge plate 104 has a folding opening adapted to the rectangular cover 106. The cavity in the rectangular cover 106 is used to insert the tobacco stick.

[0030] A servo motor 105 is located on one side of the bridge plate 104 and is used to drive the rectangular cover 106 to rotate at an angle.

[0031] Two sets of detectors 108 are respectively set above the first conveyor belt 102 and the second conveyor belt 103. U-shaped frames 107 are fixedly installed on the surfaces of the first conveyor belt 102 and the second conveyor belt 103 near the detectors 108. The detectors 108 are mounted on the U-shaped frames 107.

[0032] A photoelectric switch 110 is installed on one side of the bridge plate 104, and a light-passing hole 111 corresponding to the photoelectric switch 110 is opened on the other side of the bridge plate 104.

[0033] Fan plates 109 are fixedly installed on both sides of the bridge plate 104. A servo motor 105 is fixedly installed on the surface of one set of fan plates 109. The output end of the servo motor 105 is fixedly connected to the rectangular cover 106.

[0034] The bottom of the bridge plate 104 has multiple sets of rectangular openings arranged at equal intervals, and rollers 113 are provided at the rectangular openings. The rollers 113 are rotatably connected to the bridge plate 104 through a rotating shaft.

[0035] The support frame 101 has spacers 112 fixedly installed on both sides to limit the movement of the cigarette bar.

[0036] In this implementation plan: the cigarette conveying bridge device for cigarette equipment, the cigarette packs enter the first conveyor belt 102 from the upstream equipment, and the partition strips 112 on both sides of the support frame 101 limit the sides of the cigarette packs to prevent them from shifting left and right during the conveying process, and ensure that the cigarette packs move towards the bridge plate 104 in an upright posture.

[0037] The detector 108 above the first conveyor belt 102 is fixed by the U-shaped frame 107 and faces the surface of the cigarette pack, such as the trademark, seal and other feature areas. It collects the image information of the cigarette pack in real time and compares it with the preset template to determine whether the direction of the cigarette pack is correct. The detection results are synchronously transmitted to the control system.

[0038] The cigarette pack enters the inclined bridge plate 104 from the end of the first conveyor belt 102. The roller 113 at the bottom of the bridge plate 104 reduces the friction between the cigarette pack and the ground of the bridge plate 104 by rotating, so that the cigarette pack moves smoothly along the inclined surface. When the cigarette pack moves to the middle of the bridge plate 104, it blocks the light path between the photoelectric switch 110 and the light-penetrating hole 111. The photoelectric switch 110 sends a cigarette pack arrival signal to the control system.

[0039] If the cigarette pack is facing forward, the rectangular cover 106 remains in its initial state. The rectangular cover 106 is located below the bridge plate 104 through the folding opening in the bridge plate 104, and the cigarette pack passes directly through the bridge plate 104 to the second conveyor belt 103.

[0040] If the cigarette pack is reversed, the servo motor 105, fixed on the fan plate 109, drives the rectangular cover 106 to rotate around the axis by a specified angle. The opening of the cavity of the rectangular cover 106 is parallel to the inclined surface of the bridge plate 104. The cavity of the rectangular cover 106 first wraps and limits one end of the cigarette pack. Then, the servo motor 105, with its rotation, drives the cigarette pack to complete the movement angle flip, so that one side of the cigarette pack flips above the second conveyor belt 103.

[0041] After the cigarette stick is flipped over, one end of it first contacts the surface of the second conveyor belt 103. The friction generated by the contact causes the cigarette stick to detach from the rectangular cover 106 and then be continuously conveyed on the second conveyor belt 103.

[0042] After flipping, the rectangular cover 106 returns to its initial angle, and the cigarette pack continues to move along the bridge plate 104;

[0043] The detector 108 above the second conveyor belt 103 performs a secondary inspection on the direction of the cigarette packs to confirm the overturning correction effect and ensure that the direction of the cigarette packs entering the downstream process is 100% correct. At the same time, while the cigarette packs are overturning, the fan plates 109 on both sides can limit the overturned cigarette packs, ensuring the stability of the overturning and further improving the use effect of the device.

[0044] This solution automates the cigarette bar conveying process by using a drive structure for flipping detection and flipping, improving production efficiency, ensuring correct cigarette bar orientation, and reducing scrap rate. It is also compact, easy to operate, energy-saving, and environmentally friendly, demonstrating significant benefits.

[0045] It should be noted that all electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0046] Furthermore, any content of the detector 108 not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0047] The working principle and usage process of this utility model are as follows: This cigarette conveying bridge device for cigarette equipment allows cigarettes to enter the first conveyor belt 102. The spacers 112 on both sides of the support frame 101 limit the movement of the cigarettes, ensuring the cigarettes move upright to the bridge plate 104. The detector 108 above the first conveyor belt 102 collects real-time image information of the cigarettes, compares it with a preset template, determines whether the cigarette direction is correct, and transmits the result to the control system. The cigarettes enter the inclined bridge plate 104 from the end of the first conveyor belt 102. The roller 113 at the bottom of the bridge plate 104 reduces friction between the cigarettes and the bridge plate 104, allowing the cigarettes to move smoothly. When the cigarettes reach the middle of the bridge plate 104, they block the light path between the photoelectric switch 110 and the light-piercing hole 111. The photoelectric switch 110 then sends a signal to the control system. The system sends a signal indicating that the cigarette pack has arrived. Depending on the direction of the cigarette pack, if it is in the forward direction, the rectangular cover 106 remains in its initial state, and the cigarette pack moves directly to the second conveyor belt 103 via the bridge plate 104. If the cigarette pack is in the reverse direction, the servo motor 105 drives the rectangular cover 106 to rotate around the axis by a specified angle, wrapping and limiting one end of the cigarette pack. Then, it drives the cigarette pack to complete the rotation angle flip, causing one side of the cigarette pack to flip over to the top of the second conveyor belt 103. After the cigarette pack flips, one end of it contacts the surface of the second conveyor belt 103, and the friction causes the cigarette pack to detach from the rectangular cover 106 and continue to be conveyed on the second conveyor belt 103. The detector 108 above the second conveyor belt 103 performs a secondary detection on the direction of the cigarette pack to confirm the flipping correction effect and ensure that the direction of the cigarette pack entering the downstream process is 100% correct.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
