Description

Technical Field

[0001] This invention belongs to the technical field of cigarette packaging equipment, specifically relating to a cigarette storage warehouse suitable for different cigarette diameters. Background Technology

[0002] The cigarette storage bin is a key buffer and feeding device in the cigarette packaging production line. Its function is to temporarily store and organize the continuous stream of cigarettes conveyed by the upstream cigarette making machine, and ultimately form the specific cigarette array required by the downstream packaging machine. In the traditional production mode, a packaging production line usually only produces cigarettes of a fixed diameter. The key dimensions of the cigarette storage bin, such as the width of the internal passage and the gap of the guide plates of the sorting mechanism, are designed and fixed according to the diameter of the specific cigarette, so as to ensure the reliability of conveying and forming.

[0003] However, with the increasing market demand for various specifications of cigarettes, including slim, medium, and thick cigarettes, production lines need to be able to quickly switch between different diameter specifications. To address this need, the common practice in the industry is to configure two complete and independent cigarette storage warehouses and their downstream combing and forming modules in parallel on the same production line for different specifications of cigarettes, such as thick and slim cigarettes. In actual operation, the cigarette flow is guided to the corresponding specification's storage warehouse through a switching device in the upstream conveying channel. For example, when producing thick cigarettes, the cigarettes are introduced into a dedicated thick cigarette storage warehouse; when switching to slim cigarettes is required, the channel is switched, allowing the cigarettes to enter another dedicated slim cigarette storage warehouse.

[0004] While this "one machine, two warehouses" or even "one machine, multiple warehouses" configuration logically achieves the function of specification switching, it has revealed many inherent defects in practical applications. First, it is essentially equivalent to redundant investment; purchasing and maintaining multiple sets of large equipment significantly increases costs. Second, the two parallel tobacco warehouse systems occupy a large area, placing higher demands on the spatial layout of the production workshop. More importantly, scheduling in this model is not truly flexible: each tobacco warehouse is an independent, rigid system. If one system shuts down due to failure or maintenance, even if the product order corresponding to another tobacco warehouse on the production line is urgent, it cannot be temporarily called upon, severely restricting equipment utilization and production scheduling flexibility. Furthermore, maintenance personnel need to be familiar with two systems with different size parameters, increasing the complexity of operation and maintenance.

[0005] Therefore, the existing solution of configuring multiple independent devices to adapt to different cigarette diameters is a costly, inefficient, and inflexible approach.

[0006] This application is submitted to address the above issues. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a cigarette storage unit suitable for different cigarette diameters, thereby solving the problems of high cost, large footprint, inflexible scheduling, and complex maintenance caused by configuring multiple independent sets of equipment in traditional solutions. The present invention aims to achieve rapid and reliable adaptation of cigarettes of different diameters through a single, easily replaceable main body for the storage unit, thus significantly improving the flexibility of the production line, reducing equipment investment and operating costs, and optimizing space utilization.

[0008] The technical solution adopted in this invention is:

The invention is characterized in that a replaceable stirring roller assembly 600 is provided at the cigarette flow path inlet of the lower storage guide and combing unit 300.

[0010] The stirring roller assembly 600 includes a plurality of elongated sieve bars 602 arranged side by side. The plurality of sieve bars 602 are arranged parallel to each other and spaced apart, such that a sieve slot 603 is formed between every two adjacent sieve bars 602 to allow a single cigarette to pass through axially.

[0013] A dedicated pusher detachably connected to the push mechanism drive unit; and a packaging mold 700 detachably mounted on the downstream packaging machine conveyor station;

[0014] The dedicated pusher is used to push out the entire cigarette array arranged in the combing mechanism 302 and send it into the packaging mold 700.

[0020] Each screen bar 602 is mounted to its corresponding mounting interface 614 by its mounting drive section 602b, so that the outer ring of the rolling bearing is positioned in the bearing positioning seat. At the same time, the drive mating part 613 is connected to the output end of the drive device 616 after circumferential alignment, thereby realizing the rotatable support and power connection of the screen bar 602.

[0021] Preferably, the mounting interface 614 further includes at least one set screw; the set screw passes radially through the side wall of the bearing positioning seat, and its inner end abuts against the outer ring of the rolling bearing, for axially locking the outer ring of the rolling bearing in the bearing positioning seat after the screen bar 602 is installed in place.

[0032] The locking device, another locking device, and yet another locking device are all one of screws, elastic clips, or pins.

[0033] The beneficial effects of this invention are:

[0034] 1. This invention deconstructs the traditional monolithic tobacco storage unit into replaceable functional modules. Upstream, by replacing agitator roller assemblies with different screen gap widths, the initial flow conditions of the tobacco cigarettes are directly altered, matching the physical dimensions of cigarettes with different diameters. Downstream, by replacing the combing mechanism, dedicated pusher, and packaging mold, the dimensional matching of the cigarettes throughout the entire process from arrangement and pushing to final packaging is ensured. This modular replacement mode, with upstream screening and downstream full-process matching, allows for rapid switching from one diameter of tobacco cigarette to another on the same tobacco storage unit, requiring only the replacement of pre-prepared modules of the corresponding specifications. This solves the problems of cumbersome changeover and rigid scheduling in the traditional one-machine-two-storage mode, achieving highly efficient and flexible production.

[0035] 2. The upstream agitator roller assembly is not a simple fixed grid. Each screen bar can rotate independently and is driven by a drive unit. This design allows the screen bars to actively and axially comb through the falling cigarettes, especially the easily tangled slim cigarettes, effectively breaking up any possible accumulation or crossing, ensuring that the cigarettes pass through the screen gaps in a single row and with a stable posture before entering the downstream. This solves the congestion and disorder problems that easily occur in traditional fixed channels when adapting to slim cigarettes, laying a solid foundation for downstream combing.

[0036] 3. To achieve independent replacement and driving of the screen bars, this invention designs a specific mechanical structure: each screen bar is an independent unit, integrating a rolling bearing and a drive assembly; the frame is equipped with a corresponding mounting interface, including a bearing positioning seat and a drive device. During installation, simply place the bearing of the screen bar unit into the positioning seat (U-shaped groove or guide cone hole for easy insertion), align the drive assembly with the output end of the drive device (e.g., spline connection structure), and then axially lock it with a set screw. This design decomposes the complex rotary support and power transmission functions into replaceable units and fixed interfaces, enabling quick and independent maintenance or replacement of individual screen bars, while ensuring the rigidity of the overall installation and the reliability of the drive.

[0037] 4. This invention systematically transforms the downstream combing, pushing, and packaging processes. Instead of replacing the entire bulky mechanism, it introduces the concept of "fixed standardized interfaces." Specifically, a first standardized interface, a pusher head connection, and a second standardized interface are fixedly installed on the frame or back plate, the pushing drive component, and the downstream conveyor line, respectively. All combing mechanisms, dedicated pushers, and packaging molds adapted to cigarettes of different diameters are designed with mating parts (e.g., positioning pins, positioning blocks, etc.) that match the aforementioned fixed interfaces, and can be quickly locked using standardized fasteners (e.g., screws, buckles, etc.).

[0038] Different functional modules share the same installation benchmark, eliminating the need for operators to adjust the equipment's foundation structure. Simply align, place, and lock to complete the replacement, simplifying the process. Fixed, standardized interfaces ensure consistent installation accuracy each time, allowing the combing gap, ejection stroke, and mold cavity to immediately match the cigarette diameter after module replacement, guaranteeing packaging quality. This solution avoids the need to stock complete downstream mechanisms for each specification, requiring only the storage of key functional modules, thereby reducing spare parts inventory costs and space requirements.

[0039] 5. This invention employs a highly modular and standardized technical solution, using a "one main equipment plus multiple sets of modular components" model, replacing the traditional model of multiple complete equipment sets. This directly leads to a significant reduction in initial equipment investment and subsequent maintenance costs, while also reducing floor space required. Simultaneously, rapid changeover capabilities and high equipment utilization enhance the production line's flexibility in responding to market changes. Maintenance work also becomes simpler and more standardized due to standardized interfaces and modular independence. Therefore, this invention provides significant advancements in technology, economics, and operation, effectively addressing the main shortcomings pointed out in the background art.

Detailed Implementation

[0045] The present invention will be further described in detail below with reference to embodiments, but this is not intended to limit the invention. Any modifications or improvements made based on the teachings of the present invention fall within the protection scope of the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0046] Example 1

[0047] like Figures 1 to 3 As shown, this embodiment provides a cigarette storage container suitable for different cigarette diameters.

[0048] The cigarette storage warehouse includes a frame 100 that serves as the supporting base. On the frame 100, a storage guide unit 200 and a lower storage guide and sorting unit 300 are arranged sequentially from top to bottom.

[0049] The material storage and guiding unit 200 is used to receive the continuous tobacco stream from the upstream cigarette making machine and to perform preliminary buffering and orderly conveying. Its typical structure includes at least two side-by-side material storage chambers (or tobacco channels), each of which is enclosed by a front baffle, a back plate, and left and right side plates, providing a path for the tobacco to fall. The tobacco can fall in the material storage chamber by gravity or be controlled by an auxiliary conveying device (such as a conveyor belt) to ensure that the tobacco stream smoothly enters the downstream.

[0050] The lower storage flow guiding and sorting unit 300 is located below and connected to the storage flow guiding unit 200. It is used to receive cigarettes from above and to divert, sort, and queue them. It typically includes a vertical flow guiding cavity corresponding to the upper storage cavity. At the bottom of each vertical flow guiding cavity, a flow diversion structure (such as an inverted V-shaped flow guiding block) can be provided to evenly divide a single stream of cigarettes into multiple streams.

[0051] In this invention, a replaceable agitator roller assembly 600 is provided at the inlet of the tobacco branch flow path of the lower storage guide and combing unit 300. For example... Figure 2 As shown, the agitator roller assembly 600 is composed of multiple elongated screen bars 602 arranged side by side. The screen bars 602 are parallel to each other and spaced evenly, with a narrow screen slit 603 formed between every two adjacent screen bars 602. The width of each screen slit 603 is designed to allow only a single cigarette to pass through along its axial direction. The agitator roller assembly 600 is prefabricated in at least two specifications, each with a different screen slit 603 width, to accommodate cigarettes of different diameters (e.g., standard diameter cigarettes, medium-sized cigarettes, and slim cigarettes). When the production line needs to switch cigarette specifications, the operator removes the entire agitator roller assembly 600 from the frame 100 and replaces it with another assembly of the corresponding screen slit width, thus achieving rapid adaptation of the upstream channel.

[0052] To further improve the smoothness of cigarettes passing through the sieve openings, each sieve bar 602 is connected to a drive device (e.g., a micro motor), which drives the sieve bar 602 to rotate around its own axis. In this embodiment, the drive device consists of multiple independent motors, each corresponding to one sieve bar, and the speed and direction can be controlled individually. In operation, the rotating sieve bar 602 exerts an axial pushing and combing effect on the falling cigarettes, effectively dispersing any possible accumulation or crossing, ensuring that the cigarettes pass through the sieve openings 603 one by one in a single row and with a stable posture. This active combing method is particularly effective for easily tangled slim cigarettes.

[0053] like Figure 2 and Figure 3 As shown, to enable quick and independent maintenance or replacement of the screen bars, each screen bar 602 is designed as an independent replaceable unit. Specifically:

[0054] Each screen bar 602 has a working section 602a extending into the tobacco branch flow path at one end and a mounting drive section 602b at the other end. A rolling bearing is fixedly mounted on the mounting drive section 602b, and the inner ring of the rolling bearing is fixedly connected to the mounting drive section 602b (e.g., by interference fit or set screw). The end of the mounting drive section 602b is machined with a drive mating part 613 (e.g., external spline, polygonal shaft, or flat key shaft). A mounting interface 614 is provided on the frame 100 corresponding to each screen bar. Each mounting interface 614 includes a bearing positioning seat for receiving and positioning the outer ring of the rolling bearing, and a drive device 616 (e.g., a motor) at a position corresponding to the mounting interface. The output end of the drive device 616 (e.g., internal spline sleeve, polygonal hole, or keyway hole) and the drive mating part 613 are configured to be connected in a manner that allows torque to be transmitted in the circumferential direction and to be plugged into each other in the axial direction.

[0055] To prevent the screen bar 602 from axially slipping out of the bearing locating seat due to vibration during operation, this invention provides an axial locking structure at the mounting interface 614. Specifically, this embodiment uses a set screw as the locking element. The set screw passes radially through the side wall of the bearing locating seat, with its inner end abutting against the outer ring of the rolling bearing. After the screen bar 602 is installed in place (i.e., the outer ring of the rolling bearing is completely inside the bearing locating seat), the operator tightens the set screw to axially lock the outer ring of the rolling bearing within the bearing locating seat. In this way, even if the drive end only transmits torque without providing axial fixation, the screen bar will not "run out" under rotation or vibration. It should be noted that the axial positioning of the screen bar is entirely provided by the bearing locating seat and the set screw. The axial plug-in connection between the drive mating part 613 and the output end of the drive device 616 is only used for power transmission and convenient disassembly and assembly, and does not provide axial fixation, therefore it will not affect the working reliability of the screen bar.

[0056] To facilitate the insertion and removal of the outer ring of the rolling bearing, the bearing positioning seat is designed as either an open U-shaped groove or a through hole with a guide cone surface. The U-shaped groove has its opening facing upwards, allowing the screen bar to be placed downwards during operation, causing the bearing outer ring to fall into the groove. The guide cone surface guides the bearing outer ring axially. Both structures enable rapid positioning. Simultaneously, the bearing positioning seat also features a clearance hole for the drive mating part 613 to pass through. This clearance hole is larger than the outer diameter of the drive mating part 613, ensuring that the drive mating part can freely pass through and rotate, thus facilitating smooth connection with the output end of the subsequent drive device.

[0057] The cigarette storage compartment of the present invention also includes a replaceable downstream module fully adapted to cigarettes of a specific diameter. This module includes a combing mechanism 302 disposed below the sieve slot 603, a dedicated pusher for pushing out the entire array of cigarettes arranged in the combing mechanism 302, and a packaging mold 700 located downstream of the combing mechanism 302. To achieve rapid and precise replacement of these modules, the present invention employs a fixed standardized interface scheme.

[0058] Specifically, a first standardized interface is fixedly installed on the frame 100 (or the back plate connected to it), and the combing mechanism 302 is provided with a first mating part that matches the first standardized interface. For example, the first standardized interface is a positioning hole 721, and the first mating part is a positioning pin 720. When replacing the combing mechanism 302, it is only necessary to insert the positioning pin 720 into the positioning hole 721 to achieve precise positioning, and then fix it with a fastener (such as a hand screw).

[0059] The output end of the drive component (i.e., the linear actuator) of the ejector mechanism is provided with a fixed-size push head connection part (in this embodiment, a mounting shaft), and the dedicated push head is provided with a matching second mating part (in this embodiment, a mounting sleeve hole). During installation, the mounting sleeve hole of the dedicated push head is fitted onto the push head mounting shaft, and then tightened with another locking device (such as a set screw).

[0060] A second standardized interface, such as a positioning groove 731, is fixedly installed on the conveyor station of the downstream packaging machine. The packaging mold 700 is provided with a third mating part, such as a positioning block 730, that matches the positioning groove 731. During replacement, the positioning block 730 of the packaging mold is inserted into the positioning groove 731 for positioning, and then secured with another locking device. All locking devices can be screws, elastic clips, or pins; in this embodiment, hand-tightened screws are preferred for quick, tool-free operation.

[0061] The combing mechanism 302, the dedicated pusher, and the packaging mold 700, which are adapted to cigarettes of different diameters, all share the aforementioned first standardized interface, pusher connection, and second standardized interface. This means that modules of different specifications have the same installation reference and interface dimensions, thus ensuring positional accuracy and reliable fit after replacement. Simultaneously, the width of the cigarette inlet end of the combing mechanism 302 is matched to the width of the sieve slit 603 (for example, for a 7.8mm diameter cigarette, the sieve slit width is set to approximately 7.9mm, and the combing mechanism inlet end width is set to approximately 8.0mm), ensuring that the cigarette slides smoothly into the combing channel.

[0062] The operation of this cigarette storage unit is as follows: After the upstream cigarette stream enters the storage and guiding unit 200, it enters the lower storage guiding and combing unit 300 by gravity or auxiliary conveying. The cigarettes first reach the rotating agitator roller assembly 600, where rotating screen bars 602 actively comb them, ensuring that the cigarettes pass through the screen gaps 603 of corresponding width in a single, axial manner. The cigarettes passing through the screen gaps fall into the combing mechanism 302, where they are arranged into a neat array (e.g., 10 or 20 cigarettes) required for downstream packaging under the guidance of guide plates. Subsequently, the linear actuator of the ejection mechanism drives a dedicated pusher to smoothly push the entire array of cigarettes in the combing mechanism 302 into the packaging mold 700, completing the feeding process.

[0063] When switching from producing cigarettes of one diameter to another (e.g., from regular cigarettes to slim cigarettes), the operating steps are as follows:

[0064] (1) Stop the machine, remove the current stirring roller assembly 600, and replace it with an assembly whose screen gap width matches the diameter of the new cigarette.

[0065] (2) Loosen the fasteners, remove the current combing mechanism 302, install a combing mechanism that is compatible with the diameter of the new cigarette and fix it with fasteners.

[0066] (3) Loosen the other locking fastener and replace the special pusher head so that the width of the pusher head's push-out surface matches the gap of the guide plate (to ensure that the cigarette array can be pushed out as a whole).

[0067] (4) At the downstream station, loosen another fastener and replace it with a packaging mold 700 with a cavity that matches the diameter of the new cigarette.

[0068] (5) Check that each module is installed correctly and start production.

[0069] Since all interfaces are standardized, the entire replacement process does not require any adjustment or recalibration of the main equipment structure, and the changeover time can be shortened to a few minutes, significantly improving production flexibility.

[0070] Other optional implementation methods

[0071] In another embodiment, multiple screen bars 602 can also be connected to the same drive motor via gears or synchronous belts to achieve synchronous rotation, thereby reducing manufacturing costs. In this case, the drive device consists of only one motor, and the transmission mechanism (gear system or synchronous belt pulley) distributes power to all screen bars. This centralized drive method can also achieve the function of screen bar rotation and combing, and the structure is more compact.

[0072] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions described in the drawings and embodiments are not related to the specific physical object and are not used to limit the protection scope of this application. The physical dimensions can be selected and changed according to actual needs.
