Description

Technical Field

[0001] This patent belongs to the technical field of cigarette storage material distribution equipment, specifically relating to a device for turning over and preventing cigarette cartons from tipping over during the conveying process before stacking in a finished cigarette warehouse. Background Technology

[0002] In the field of cigarette production automation, adjusting the posture of cigarette cartons before palletizing is a crucial step in ensuring both logistics efficiency and palletizing quality during the finished product warehouse receiving process. Cartons transported from upstream production to the finished product warehouse are typically laid flat, while robotic palletizing requires them to be stacked upright with the box icons and text aligned correctly. Therefore, how to efficiently and economically adjust the posture of cigarette cartons from flat to upright before palletizing has been a long-standing technical challenge for the industry.

[0003] Traditional solutions often involve extending the logistics conveyor line or adding turning conveyor equipment, using space to buy time for attitude adjustment. For example, by setting up multiple inclined roller conveyors or turning mechanisms, cigarette packs are forced to naturally tumble during transport due to gravity or mechanical force. However, this method has significant drawbacks: First, the conveyor line length increases dramatically, leading to a decrease in factory space utilization, especially in modern cigarette factories where space is extremely valuable, resulting in high space costs. Second, the tumbling process relies on the friction between the cigarette packs and the conveyor surface; for cigarette packs with smooth surfaces or special materials, slippage and jamming are likely to occur, resulting in a low success rate of adjustment. Third, it is difficult to balance tumbling speed and stability; rapid transport can easily cause cigarette packs to tip over, while slowing down affects overall logistics efficiency, creating a contradiction between "space and time."

[0004] In recent years, some technologies have attempted to achieve active tilting through complex mechanical structures. For example, CN103274194A discloses a conveying device for automatically adjusting the posture of cigarette boxes, which uses a short roller assembly in conjunction with an L-shaped tilting frame and controls the tilting angle through sensors. However, this solution has the following shortcomings: First, the tilting frame is a fixed structure, which can only accommodate cigarette boxes of specific sizes. For irregularly shaped cigarette boxes with large differences in width and height, it is easy to experience positioning failure or over-tilting. Second, it relies on multiple sets of sensors (such as tilting start sensors and reset sensors) to achieve closed-loop control, resulting in high system complexity and maintenance costs. Finally, it lacks an effective buffering mechanism, and cigarette boxes are prone to tipping over due to inertia after rapid tilting, requiring additional baffles or manual intervention, which reduces efficiency.

[0005] Another type of technology, CN119460501A, achieves passive flipping by limiting the distance between the guide plate and the guardrail, but its adaptability is weaker: the distance between the guide plate and the guardrail must be strictly matched with the size of the cigarette pack. Once the production batch changes (such as switching from standard cigarette packs to irregularly shaped cigarette packs), the machine must be stopped for adjustment, otherwise the cigarette packs may get stuck or the flipping may fail. In addition, this solution does not solve the inertia problem after flipping. After the cigarette packs leave the guide plate, they may still tip over due to the excessive conveying speed, especially for lighter cigarette packs, where the stability is even worse.

[0006] This utility model proposes an innovative solution to the above problems. Through the combined design of "adjustable buffer device + flipping mechanism step structure", it achieves efficient and stable adjustment of cigarette posture in a limited space, while taking into account the adaptability of cigarettes of different sizes. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable cigarette box anti-tipping device to address the problems mentioned above. This invention achieves efficient and stable adjustment of the cigarette box posture within a limited space, while also taking into account the adaptability requirements of cigarette boxes of different sizes.

[0008] The technical solution of this utility model is as follows: This utility model discloses an adjustable anti-tipping device for a parts box, comprising a roller conveyor, an adjustable buffer device, and a tilting mechanism; the roller conveyor is designed in sections at the tilting station, with the tilting mechanism nested in the middle; the adjustable buffer device is installed on the side of the roller conveyor and fixedly installed through a strip-shaped waist hole.

[0009] The roller conveyor enables continuous transport of cigarette packs. Its segmented design provides installation space for the flipping mechanism, ensuring seamless connection between the transport and flipping processes. The flipping mechanism is embedded in the roller conveyor, directly contacting the cigarette packs and adjusting their posture (from lying flat to standing). The adjustable buffer device adjusts its position through strip-shaped waist holes to accommodate cigarette packs of different sizes and prevents them from tipping over after flipping.

[0010] Furthermore, the adjustable buffer device includes a gantry-type support and a buffer element mounted on the support. The buffer element is a foam pad located above the tilting mechanism. The gantry-type support spans above the roller conveyor, providing stable support for the buffer element. The foam pad can cushion the inertial impact on the top of the upright cigarette pack, preventing it from tipping over due to excessive turning speed.

[0011] Furthermore, the flipping mechanism includes a flipping arm and a step structure. The step structure protrudes from the conveying surface and is used to hold the cigarette in place to prevent it from sliding during the initial flipping stage. The flipping arm drives the cigarette to rotate and completes the posture adjustment. The step structure holds the bottom of the cigarette in place during the initial flipping stage to prevent it from sliding with the conveying surface and ensures the synchronicity of the flipping.

[0012] Furthermore, at the turning station of the roller conveyor, the conveyor rollers are segmented and disconnected, with the turning shaft of the turning mechanism nested in the middle. The segmented design provides installation space for the turning shaft while maintaining the overall continuity of the conveyor line. The embedded turning shaft realizes the integration of the turning mechanism and the roller conveyor, reducing the additional space occupation.

[0013] Furthermore, the adjustable buffer device can be adjusted in position via a strip-shaped waist hole to accommodate the top buffering requirements of cigarette packs of different sizes. The strip-shaped waist hole allows for on-site adjustment of the horizontal position of the buffer device to match cigarette packs of different widths / heights, thus improving the adaptability of the device.

[0014] Furthermore, during the flipping process, the flipping arm of the flipping mechanism gradually rotates the cigarette pack from a lying position to an upright position. This gradual rotation avoids inertial loss of control caused by rapid flipping and ensures a smooth transition in the cigarette pack's posture.

[0015] Furthermore, the adjustable buffer device has a gantry-type support spanning above the roller conveyor, and the bottom of the support is bolted to the side of the roller conveyor. The spanning design ensures that the buffer device covers the area above the overturning mechanism and effectively contacts the top of the vertical component. The bolted connection facilitates installation, disassembly, and position adjustment, adapting to on-site maintenance needs.

[0016] Furthermore, the stepped surface of the flipping mechanism is provided with anti-slip texture to enhance the friction with the bottom of the cigarette pack. The anti-slip texture further prevents the cigarette pack from sliding in the initial flipping stage, improving the reliability of the locking mechanism.

[0017] Furthermore, the roller conveyor has separate power sections in the conveying sections before, in the middle and after the flipping station. At the flipping station, three short rollers replace the long rollers and are nested with a flipping mechanism. Each of the three roller sections uses a multi-wedge belt to maintain power, and continuous conveying ensures that the flipping process does not affect the overall logistics rhythm and improves palletizing efficiency.

[0018] Furthermore, the buffer component of the adjustable buffer device is vertically aligned with the flipping mechanism. By adjusting the height, it matches the smoke height of each product specification on the production line, ensuring that the height of the buffer component is consistent with the top height of the vertical smoke component. Vertical alignment ensures that the buffer component acts directly on the center area of ​​the top of the vertical smoke component, maximizing the buffering effect. Consistent height avoids the buffer component being too low (ineffective) or too high (unreachable), ensuring functional reliability.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. The adjustable buffer device of the adjustable component box anti-tipping device of this utility model is a gantry-type bracket spanning above the flipping mechanism. The buffer (foam pad) is at the same height as the top of the upright cigarette box, directly counteracting the flipping inertia. Through the dual action of physical contact and mechanical limiting, the tipping problem caused by inertia during the flipping process is solved, ensuring that the cigarette box enters the subsequent stacking process in a stable upright posture.

[0020] 2. The present invention integrates the flipping mechanism with the roller conveyor, avoiding the space requirement of setting up a separate turning conveyor line in the traditional solution; the adjustable buffer device is directly installed on the side of the existing conveyor line, reducing the equipment footprint and complexity, and significantly reducing manufacturing costs.

[0021] 3. This utility model, through the combination of adjustable structure and anti-slip design, enables the device to be compatible with the flipping requirements of standard and irregularly shaped smoke parts, avoiding equipment downtime for adjustment due to changes in smoke part size, and improving the flexibility and versatility of the production line.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0025] 1. For example Figure 1 The diagram shows the overall layout of this device: like Figure 1 As shown, the device is installed on the conveyor line before stacking finished cigarettes in the cigarette factory's 4th finished product warehouse, and includes: Roller conveyor 1: Composed of multiple sets of conveyor rollers, the conveyor rollers are segmented at the turning station, and the turning mechanism 3 is nested in the middle; Adjustable buffer device 2 is installed on the side of roller conveyor 1 and fixed through the strip waist hole 21, spanning above the turning mechanism 3; Turning mechanism 3: Nested at the turning station A of roller conveyor 1, including turning arm 31 and step structure 32.

[0026] 2. Structure and installation of key components: 2.1 Roller Conveyor 1: The conveyor rollers are interrupted at the flipping station, and the width of the interrupted area matches the length of the flipping shaft 33 of the flipping mechanism 3. The conveyor sections before and after the flipping station A keep running continuously to ensure that the logistics rhythm is not affected by the flipping process.

[0027] 2.2 Adjustable buffer device 2: The bottom of the gantry bracket 22 is connected to the side of the roller conveyor 1 by bolts, and the strip-shaped waist hole 21 allows for horizontal adjustment of the installation position; the top of the bracket 22 is fixed with a foam pad 23, the bottom height of the foam pad 23 is consistent with the top height of the vertical component smoke 4, and it is vertically aligned with the flipping mechanism 3.

[0028] 2.3 Tilting Mechanism 3: like Figures 2-4 As shown, the tilting arm 31 is connected to the tilting shaft 33 and is controlled to rotate by a drive motor (not shown in the figure); the stepped structure 32 protrudes from the surface of the tilting arm 31 and is provided with anti-slip texture 321 to hold the bottom of the cigarette 4 in place.

[0029] 3. Implementation steps; Step 1: Cartridge 4 is conveyed horizontally to the right to the flipping station, where it is transported by roller conveyor 1; The flat-lying cigarette pack 4, delivered from upstream, is precisely positioned at the flipping station to ensure its initial position for subsequent flipping operations. If the cigarette pack 4 does not arrive at the flipping station correctly, the flipping mechanism 3 may fail to make effective contact or may fail to engage properly.

[0030] Step 2: The flipping mechanism 3 flips at a small angle, and the stepped structure 32 protrudes from the conveying surface to hold the cigarette piece 4 in place; The stepped structure 32 contacts the bottom of the cigarette 4 in advance to prevent it from sliding due to inertia or insufficient friction of the conveying surface during the initial flipping stage. A slight tilt ensures that the stepped structure 32 is only locked in place without pushing the cigarette 4, thus avoiding loss of control due to sudden tilting. The protrusion height of the stepped structure 32 needs to be precisely designed to ensure reliable locking without hindering subsequent tilting, and its surface anti-slip texture 321 can enhance the friction with the bottom of the cigarette 4.

[0031] Step 3: The cigarette 4 flips under the contact of the flipping mechanism 3; The system ensures a smooth transition of the cigarette pack 4 from a horizontal to a vertical position. The tilting arm 31 rotates the cigarette pack 4 via mechanical contact, while the stepped structure 32 continuously engages to prevent slippage. If the cigarette pack 4 does not tilt, it may cause jamming or the equipment to run idle, affecting efficiency.

[0032] Step 4: Flip cigarette 4 to a 90° upright position; The core objective of achieving the posture adjustment is to ensure that cigarette pack 4 enters the subsequent palletizing process in an upright position, ensuring that the text / icons are upright.

[0033] Key technology: The flipping angle needs to be precisely controlled at 90°. Excessive error will lead to palletizing failure or improper posture.

[0034] Step 5: The flipping mechanism 3 stops, and the cigarette 4 continues to flip due to inertia and hits the adjustable buffer device 2; The adjustable buffer device 2's foam pad 23 absorbs the inertial kinetic energy of the smoke component 4, preventing it from tipping over due to excessive rotation; the flexible contact of the foam pad 23 protects the smoke component 4's housing from damage. If there is no adjustable buffer device 2, the rapidly stopping tilting mechanism 3 may cause the smoke component 4 to rebound or tip over.

[0035] Step 6: Reset the flipping mechanism 3; The flipping mechanism 3 returns to its initial position to prepare for the next flipping operation, thus achieving cyclical operation. The reset must be quick and precise to avoid affecting the continuous conveying of subsequent cigarette items 4. The length of its flipping shaft 33 matches the width of the interrupted area of ​​the roller conveyor 1 to ensure smooth movement.

[0036] Step 7: The cigarette pack 4 continues to be conveyed forward in an upright position; Once the verification device has completed its function, the vertical cigarette pack 4 is successfully conveyed to the palletizing station and enters the next process step. If this step fails, such as the cigarette pack 4 tipping over, the entire posture adjustment process will fail, and it is necessary to backtrack and check the position of the foam pad 23 of the adjustable buffer device 2 or the positioning accuracy of the flipping mechanism 3.

[0037] Adjustment method for smoke 4 to accommodate different sizes: Adjust the horizontal position of the adjustable buffer device 2 by adjusting the strip waist hole 21 so that the foam pad 23 is aligned with the top of the cigarette 4 of different widths / heights; adjust the initial locking angle of the flipping mechanism 3 to match the bottom size of the cigarette 4 to ensure that the step structure 32 effectively locks the cigarette 4.

[0038] This embodiment achieves efficient and stable flipping of cigarette packs 4 from lying flat to standing by the coordinated action of roller conveyor 1, adjustable buffer device 2 and flipping mechanism 3. It has a compact structure and strong adaptability, meeting the posture adjustment needs of cigarette factories before stacking.

[0039] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
