Description

Technical Field

[0001] This utility model relates to the field of cigarette pack sorting technology, and in particular to a cigarette pack combining buffer device. Background Technology

[0002] In automated sorting systems for non-standard cigarettes, cartons of cigarettes need to be grouped according to order quantity before entering the order consolidation line. The traditional method uses a vacuum adsorption belt conveyor to position the cartons, creating detection gaps between adjacent cartons by intermittently starting and stopping the belt, allowing photoelectric sensors to count accurately. However, this start-stop operation results in discontinuous conveying, low cigarette output efficiency, and long waiting times on the sorting line. When order volume is large and the specifications of non-standard cigarettes vary significantly, it easily leads to congestion on the sorting line, further reducing sorting efficiency.

[0003] In view of this, the present invention provides a new solution to the above problems. Utility Model Content

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should be noted that this single-buffered smoke collection device is applied to the rear end of the vacuum adsorption belt conveyor 4 and is located between the smoke outlet of the vacuum adsorption belt conveyor 4 and the sorting line.

[0033] Example: A single-pack cigarette buffer device, such as Figure 1-6 As shown, the system includes a belt conveyor 1, an interception mechanism 2, and a control device. The belt conveyor 1 is used to transport cigarette packs 5 and is designed with an inclined ramp. The lower end is the discharge end, and the higher end is the feed end, connecting to the outlet of a vacuum adsorption belt conveyor 4. This allows the cigarette packs 5 to automatically enter the belt conveyor 1 after being adsorbed and positioned by the vacuum adsorption belt conveyor 4. The interception mechanism 2 is located on the belt conveyor 1 and is used to intercept the cigarette packs 5. It releases the cigarette packs 5 when the number of cigarette packs 5 on the belt conveyor 1 matches the quantity of a certain order.

[0034] In the above technical solution, by connecting the high end of the belt conveyor 1 to the outlet of the vacuum adsorption conveyor, gravity assists the cigarette pack 5 to slide down, achieving a seamless connection between positioning and buffering conveying of the cigarette pack 5. The baffle 22 only allows passage when the order quantity meets the target, and maintains static interception at other times, which can reduce the frequency of mechanical operation, extend the equipment life, and maintain the continuity of conveying.

[0035] Preferably, the intercepting mechanism 2 is located at the lower end of the belt conveyor 1.

[0036] The interception mechanism 2 is located at the lower part of the conveyor so that the cigarette packs 5 slide down and are closely arranged under the conveying of the belt conveyor 1 and the action of gravity, so that the cigarette packs 5 in a certain order are concentrated on the belt conveyor 1 in advance. When the order consolidation order is executed, the cigarette output efficiency can be greatly improved, the waiting time of the sorting line can be reduced, and the sorting efficiency of cigarette packs 5 can be further improved.

[0037] Reference Figure 1-6 The interception mechanism 2 includes a support column 21, a baffle 22, a drive component, and an anti-pinch component 24. The support column 21 is fixed to the frames on opposite sides of the belt conveyor 1. The drive component is mounted on the support column 21 and is used to drive the baffle 22 to rotate. The baffle 22 is located above the belt of the belt conveyor 1 and is used to intercept the cigarette pack 5.

[0038] Furthermore, the baffle 22 spans above the belt conveyor 1, initially positioned in an interception state perpendicular to the belt surface of the belt conveyor 1.

[0039] Furthermore, the baffle 22 spans the entire width of the belt conveyor 1, or the baffle 22 and the belt conveyor 1 are reserved with 1cm on each side.

[0040] Furthermore, the direction of rotation of the baffle 22 when releasing is upward along the conveying direction of the belt conveyor 1.

[0041] In the above technical solution, the support columns 21 are symmetrically fixed on both sides of the conveyor frame, forming a stable support structure to ensure that the baffle 22 does not deviate or vibrate during the interception process. In the vertical interception state, the baffle 22 remains strictly perpendicular to the belt surface, ensuring uniform force on the contact surface of the cigarette packs 5, thus improving interception stability and allowing the cigarette packs 5 in a given order to be arranged sequentially on the belt surface along the conveyor belt 1. When releasing, the baffle 22 rotates towards the lower end of the belt, forming a sloping guide surface in the same direction as the belt's movement, facilitating the smooth release of the cigarette packs 5 queue on the belt conveyor 1 and preventing stagnation or jamming.

[0042] Preferably, the driving component includes a motor 231, a rotating shaft 232, and a bearing housing 233. The motor 231 is mounted on a support column 21. The rotating shaft 232 passes through the top of a baffle 22 along the width direction of the belt conveyor 1, and the baffle 22 is fixedly connected to the rotating shaft 232. One end of the rotating shaft 232 is connected to the output shaft of the motor 231, and the other end is rotatably connected to the support column 21 via the bearing housing 233. The bearing housing 233 is fixed to another support column 21 and serves to support the end of the rotating shaft 232.

[0043] Furthermore, motor 231 is a servo motor, which is used to drive baffle 22 to rotate around shaft 232 to achieve interception / release switching.

[0044] Preferably, the control device includes a controller and a photoelectric sensor 31. The photoelectric sensor 31 is installed on one side of the belt conveyor 1 and located at the higher end of the belt conveyor 1. The controller is electrically connected to the photoelectric sensor 31 and the motor 231. The photoelectric sensor 31 is used to detect the number of cigarette packs 5 passing through in real time. The controller is used to receive the signal from the photoelectric sensor 31 and control the motor 231 to operate. When the count reaches the order quantity, the controller drives the baffle 22 to rotate, so that the cigarette packs 5 are conveyed by the belt conveyor 1 and pass through the baffle 22 in sequence to enter the sorting line.

[0045] Preferably, the photoelectric sensor 31 is a high-precision reflective photoelectric sensor with a response time of ≤1ms, which accurately identifies the cigarette pack 5 entering the belt conveyor 1.

[0046] Preferably, the controller is a PLC controller, specifically the NA-200 or Siemens S7-1200.

[0047] Preferably, the rotation angle of the baffle 22 when releasing the cigarette packs can be adjusted appropriately according to the height of the cigarette packs 5. If the rotation angle is too large, the stroke will be too long. Therefore, it is sufficient to ensure that the cigarette packs 5 can pass smoothly through the baffle 22 under the conveyor belt 1.

[0048] In the above technical solution, a high-precision reflective photoelectric sensor (response time ≤ 1ms) captures the signal of the cigarette pack 5 entering in real time, and the controller controls the servo motor to move based on a preset order threshold. The photoelectric sensor 31 maintains a high recognition accuracy under belt vibration and ambient light changes, avoiding false triggering or missed detection, and has strong anti-interference capabilities.

[0049] Preferably, the anti-pinch component 24 is located at the bottom of the baffle 22 and above the belt of the belt conveyor 1. The anti-pinch component 24 includes a roller 241, a connecting plate 242 and a connecting shaft 244. The connecting plate 242 is fixed on both sides of the bottom of the baffle 22, and the two ends of the connecting shaft 244 are respectively fixed on the two connecting plates 242. The roller 241 is sleeved on the connecting shaft 244.

[0050] Specifically, the distance between the roller 241 and the belt of the belt conveyor 1 is slightly less than the height of the cigarette bar 5, that is, when the roller 241 intercepts the cigarette bar 5, it only needs to lightly touch the cigarette bar 5.

[0051] Furthermore, the distance between the roller 241 and the belt is set to 80%-90% of the height of the cigarette pack 5, so that only a slight touch is needed to trigger the interception.

[0052] Preferably, multiple rollers 241 are provided, and the multiple rollers 241 are distributed sequentially along the axial direction of the connecting shaft 244, which is consistent with the width direction of the belt conveyor 1.

[0053] In the above technical solution, the roller 241 adopts multiple designs so that different specifications of cigarette strips 5 can effectively trigger the interception action, adapting to mixed order scenarios.

[0054] Preferably, a gap is provided between adjacent rollers 241, and a limit block 243 is provided in the gap, which is fixed on the connecting shaft 244.

[0055] In the above technical solution, the limiting block 243 is mainly set to prevent the roller 241 from moving axially.

[0056] Preferably, roller 241 is a silicone or rubber roller 241.

[0057] In the above technical solution, the roller 241 is made of soft silicone or rubber, which undergoes elastic deformation when in contact with the cigarette pack 5, creating a "soft landing" cushioning effect and reducing the scratch rate on the outer packaging of the cigarette pack 5. The roller 241 rotates as the cigarette pack 5 moves, reducing the sliding resistance of the cigarette pack 5.

[0058] In the above technical solution, the anti-pinch component 24 is designed so that when the baffle 22 intercepts, the roller 241 blocks the movement of the cigarette pack 5, preventing the packaging of the cigarette pack 5 from being damaged or deformed due to hard squeezing or jamming during the conveying process. The roller 241, made of elastic material (such as silicone / rubber), absorbs the inertia of the cigarette pack 5, reducing the damage to the equipment and materials caused by instantaneous impact, and has a good protective effect.

[0059] In summary, this cigarette pack merging buffer device is applied to the rear end of the vacuum adsorption belt conveyor 4, and is located between the smoke outlet of the vacuum adsorption belt conveyor 4 and the sorting line. This invention, by adding a cigarette pack merging buffer device between the smoke outlet of the vacuum adsorption belt conveyor 4 and the sorting line, pre-concentrates the cigarette packs 5 from a particular order into this device. When the merging order command is executed, it can significantly improve the smoke output efficiency, reduce the waiting time on the sorting line, and further improve the sorting efficiency of the cigarette packs 5. It solves the problem of low sorting efficiency caused by intermittent start-stop operations in existing irregular cigarette sorting.
