Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing, and in particular to an anti-blocking and evacuation system for the inlet channel of a cigarette pack buffer in a high-speed packaging machine. Background Technology

[0002] High-speed packaging units (such as the GDX6S) are responsible for producing conventional cigarette packs. The cigarette pack buffer (PB15) is a crucial component of the GDX6S high-speed packaging unit, serving as a buffer device for storing and compensating cigarette packs between the main machine and downstream machines, thus acting as a production buffer between the upstream and downstream processes. However, in actual production operation, the inlet of the cigarette pack buffer is prone to frequent cigarette jamming, severely impacting equipment efficiency, causing material waste, and creating a situation where it is difficult to balance the operating speeds of the main machine and downstream machines.

[0003] Analysis revealed that the PB15 cigarette pack buffer has two conveyor belts in its inlet channel: one to transport cigarette packs to the downstream machine, and the other to the buffer. When a cigarette pack enters the slide rail of the original machine's conversion device, the side of the pack, located between the two belts, contacts the belts, while the middle of the pack contacts the surface of the original machine's support between the two belts. Due to the different coefficients of friction between the pack and the belts and support surfaces (the original machine's support surface is relatively smooth), the frictional force experienced by the pack is uneven as it moves through the inlet channel, causing the pack to become stuck at the inlet of the buffer.

[0004] When the main packaging equipment is running normally, the continuous output of cigarette packs makes the blockage of cigarette packs during slide rail rerouting less noticeable and easily overlooked. However, when the main equipment stops or is in standby mode, the lack of continuous cigarette pack delivery leads to unavoidable cigarette pack stagnation. This stagnation can block the original machine's photoelectric detection signal, causing the unit to misjudge that the main equipment is still running. If the downstream machine has already stopped, slide rail rerouting can cause cigarette pack blockage, crushing, and other production accidents. The conversion device at the cigarette pack buffer inlet may fail to convert due to mismatch with the original machine's belt operation or slow operation of the original machine's conversion cylinder. This exacerbates cigarette pack blockage and cigarette pack crushing during the stop and standby phases of upstream and downstream machines. This problem not only affects production efficiency but also generates a large amount of material consumption. Summary of the Invention

[0005] In view of the above, the present invention aims to provide a high-speed packaging machine tobacco pack buffer inlet channel anti-blocking and emptying system to solve the aforementioned technical problems.

[0006] The technical solution adopted in this invention is as follows:

[0007] This invention provides a high-speed packaging machine cigarette pack buffer inlet channel anti-blocking and emptying system, including: an intermediate conveyor belt located between two original machine conveyor belts, the intermediate conveyor belt being equipped with a dedicated functional pulley set, the functional pulley set including a plurality of driven guide pulleys and a plurality of tensioning pulleys, the intermediate conveyor belt being tensioned and guided via the functional pulley set;

[0008] The roughness of the intermediate conveyor belt is greater than the surface roughness of the original machine frame, and the intermediate conveyor belt runs on the same horizontal plane as the two original machine conveyor belts. The driven pulley of the original machine conveyor belt is used as the driving pulley of the intermediate conveyor belt.

[0009] In at least one of the possible implementations, four tensioning wheels are installed at the original guide wheel mechanism, and two of the tensioning wheels form a tensioning wheel assembly located on one side of the intermediate conveyor belt, with two driven guide wheels installed on both sides of each tensioning wheel assembly.

[0010] In at least one of the possible implementations, four additional driven guide wheels are provided between the two sets of the tension wheel assemblies.

[0011] In at least one of the possible implementations, the width of the intermediate conveyor belt is smaller than the gap between the two original machine conveyor belts.

[0012] In at least one of the possible implementations, the intermediate conveyor belt is a nylon rubber conveyor belt.

[0013] In at least one possible implementation, the anti-clogging and venting system further includes a metal wheel bracket, which is fixed to the track frame of the original conveyor belt and is used to assemble the functional wheel set.

[0014] In at least one possible implementation, the wheel set bracket is made of aluminum alloy.

[0015] In at least one possible implementation, the anti-clogging and venting system further includes a wheel assembly protective cover disposed outside the functional wheel assembly, the wheel assembly protective cover being constructed of perforated aluminum plate.

[0016] Compared with existing technologies, the main design concept of this invention lies in adding an intermediate conveyor belt between the two existing conveyor belts in the channel, and combining this with the matching tensioning wheel and guide wheel, so that the three belts run synchronously on the same horizontal plane. Furthermore, the surface of this intermediate conveyor belt is rougher than the original machine's support surface, increasing the friction on the cigarette packs and allowing them to pass smoothly through the inlet of the cigarette pack buffer. This eliminates the problem of blockage and damage to cigarette packs when the conversion device operates. This invention effectively solves the problem of cigarette pack blockage and damage at the inlet of the cigarette pack buffer in high-speed packaging units caused by slide rail changes, without damaging the original machine structure, thus improving equipment operating efficiency and product quality stability. Actual verification statistics show that after installing this system, the number of waste cigarette packs generated due to blockage during each slide rail change at the PB15 inlet is 0, achieving the design target. Therefore, it ensures the quality of the cigarette packs and reduces labor and material costs. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein:

[0018] Figure 1 This is a top-view schematic diagram of the anti-blocking and venting system for the inlet channel of the cigarette pack buffer in a high-speed packaging unit provided in an embodiment of the present invention;

[0019] Figure 2 For relative Figure 1 A top-down view. Detailed Implementation

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] This invention proposes an embodiment of an anti-blocking and evacuation system for the inlet channel of a cigarette pack buffer in a high-speed packaging machine. The following detailed description is provided in conjunction with the design process of the entire system. Figure 1 and Figure 2 As shown, this includes: adding an intermediate conveyor belt 1 between the two original conveyor belts 100, and configuring a dedicated functional pulley set for the intermediate conveyor belt 1. The functional pulley set includes several driven guide pulleys 2 and several tensioning pulleys 3. The intermediate conveyor belt 1 is tensioned and guided by the functional pulley set. The roughness of the intermediate conveyor belt 1 is greater than that of the original machine frame. Figure 2The surface roughness of the area covered by the intermediate conveyor belt 1 between the two original conveyor belts 100 in the diagram is shown, and the intermediate conveyor belt 1 runs on the same horizontal plane as the two original conveyor belts 100. When selecting the drive (power design) for the added intermediate conveyor belt and its functional pulley set, it can be determined by calculating the belt speed, power, belt tension, etc. that the added intermediate conveyor belt 1 should run synchronously with the original conveyor belts 100. Therefore, the tension must be the same as that of the original conveyor belts 100. Thus, in this embodiment, the driven pulley of the original conveyor belt 100 is considered as the driving pulley of the added intermediate conveyor belt 1. And through calculation and practice, such a power design will not affect the drive motor of the original conveyor belt.

[0022] Specifically, regarding the functional wheel set, in order to adjust the tension of the intermediate conveyor belt 1 and ensure its smooth operation, in actual operation, four tensioning wheels 3 can be added to the original guide wheel mechanism, and two tensioning wheels 3 form a tensioning wheel assembly located on one side of the corresponding intermediate conveyor belt 1. In order to ensure the tensioning effect of the tensioning wheels 3, two driven guide wheels 2 are installed on both sides of each set of tensioning wheel assemblies (a total of four driven guide wheels 2 in this embodiment).

[0023] Based on the limitation of the installation position of the cigarette pack buffer inlet channel, the length of the belt can be determined to be 5400mm. The span of the starting point of the conveyor belt is relatively large. In order to ensure the smooth operation of the intermediate conveyor belt 1 and prevent it from jumping off the trough, based on mechanical principles, in some preferred embodiments, four driven guide wheels are added between the two sets of tension wheel assemblies. That is, the number of driven guide wheels in this preferred scheme is eight.

[0024] Furthermore, actual measurements show that the gap between the two original conveyor belts 100 in the PB15 cigarette pack buffer inlet channel is 30mm. Therefore, the newly added intermediate conveyor belt 1 must fill this gap without interfering with the operation of the original conveyor belts 100. Specifically, the width of the intermediate conveyor belt 1 is smaller than the gap (30mm) between the two original conveyor belts 100. Based on this design concept, and according to common belt widths such as 30mm, 25mm, and 20mm, a 25mm wide belt can be selected in actual implementation. Combined with the length mentioned above, the specifications of the intermediate conveyor belt can be 5400×25×1.5 (mm), and a nylon rubber conveyor belt with high tensile strength, low elongation, and low wear is preferred.

[0025] To facilitate the addition of the aforementioned intermediate conveyor belt and its functional pulleys to the original equipment, and to ensure the reasonable and reliable assembly of the tensioning pulley 3 and the driven guide pulley 2, the anti-clogging and venting system may also include a pulley bracket (not shown in the figure). Specifically, the pulley bracket can be bolted to the track frame of the original conveyor belt. 45# steel and aluminum alloy can be considered as materials. However, considering the load-bearing capacity of the original bracket, the material of the pulley bracket must ensure machinability and tensile strength. Therefore, aluminum alloy with lower hardness, lower density, and higher yield strength is preferred. The specifications and dimensions of the pulley bracket can be referenced as 210×40×20 (mm).

[0026] Finally, it can be added that the concept of this system is to add additional components to the original unit equipment. In order to ensure the safety and reliability of the new components and the overall compatibility with the original equipment, the anti-clogging and venting system can preferably include a wheel set protective cover (not shown in the figure) covering the outside of the functional wheel set. The material of the wheel set protective cover can be stainless steel sheet or perforated aluminum sheet. However, considering the actual packaging workshop and equipment layout, and taking into account the ventilation and heat dissipation, processability, aesthetics and cost of the wheel set protective cover, perforated aluminum sheet is preferred. The specifications and dimensions of the wheel set protective cover bracket can be referenced as 220×160×100 (mm).

[0027] In summary, the main design concept of this invention lies in adding an intermediate conveyor belt between the two existing conveyor belts in the channel, and combining this with the matching tensioning wheel and guide wheel, so that the three belts run synchronously on the same horizontal plane. Furthermore, the surface of this intermediate conveyor belt is rougher than the original machine's support surface, increasing the friction on the cigarette packs and allowing them to pass smoothly through the inlet of the cigarette pack buffer. This eliminates the problem of blockage and damage to cigarette packs when the conversion device operates. This invention effectively solves the problem of cigarette pack blockage and damage at the inlet of the cigarette pack buffer in high-speed packaging units caused by slide rail changes, without damaging the original machine structure, thus improving equipment operating efficiency and product quality stability. Actual verification statistics show that after installing this system, the number of waste cigarette packs generated due to blockage during each slide rail change at the PB15 inlet is 0, achieving the design target. Therefore, it ensures the quality of the cigarette packs and reduces labor and material costs.

Furthermore, "at least one" refers to one or more, and "more than one" refers to two or more.
