Description

Technical Field

[0001] The present invention relates to the technical field of tobacco machinery, and particularly to a cigarette outlet wheel set and a tobacco production device. Background Art

[0002] Currently, when cigarette factories produce cigarettes, in order to improve production efficiency, various devices are usually connected to each other to achieve automated production. For example, a packaging machine is connected to the rear side of a filter rod assembler to achieve automated synchronous production of filter rod assembly and cigarette packaging.

[0003] With the continuous upgrading or technological transformation of the devices on the cigarette factory production line, for example, after the packaging machine is upgraded, new requirements are put forward for the cigarette input height, and the filter rod assembler must correspondingly adjust the cigarette outlet height to ensure precise connection with downstream devices such as the packaging machine, so as to ensure the coherence and efficiency of the production process. In addition, with the expansion of the cigarette factory production scale or the optimization of the production process, the layout of the workshop equipment may need to be re-planned.

[0004] However, the tobacco production devices in the current technology usually can only discharge cigarettes at one position, resulting in the inability of the upstream tobacco production devices to be normally connected to the downstream devices after the downstream devices are updated or transformed.

[0023] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in this technology to understand and read, and are not used to limit the limited conditions under which this application can be implemented.

[0024] The present invention provides a smoke outlet wheel set, which includes a low-position smoke outlet wheel and a high-position smoke outlet wheel set; the high-position smoke outlet wheel set is arranged above the low-position smoke outlet wheel, and the negative pressure state of the high-position smoke outlet wheel set can be controlled independently; the high-position smoke outlet wheel set includes a transmission wheel and a high-position smoke outlet wheel arranged in sequence, the transmission wheel is docked with the low-position smoke outlet wheel, and the discharging position of the high-position smoke outlet wheel is higher than that of the low-position smoke outlet wheel; the smoke outlet wheel set has a low-position smoke outlet mode and a high-position smoke outlet mode. In the low-position smoke outlet mode, materials are output through the low-position smoke outlet wheel; in the high-position smoke outlet mode, materials are transferred from the low-position smoke outlet wheel to the high-position smoke outlet wheel set and output through the high-position smoke outlet wheel. The low-position smoke outlet wheel and the high-position smoke outlet wheel are arranged in the smoke outlet wheel set, and the negative pressure state of the high-position smoke outlet wheel set can be controlled independently. Therefore, by controlling the negative pressure state of the high-position smoke outlet wheel set, the smoke outlet wheel set can smoke from the low-position smoke outlet wheel or from the high-position smoke outlet wheel, and the smoke outlet position can be flexibly adjusted to adapt to downstream equipment, so as to maintain the coordinated operation of the overall production line and the stability of product quality.

[0025] Please refer to Figures 1 to 5 , in an embodiment, a smoke outlet wheel set 100 is provided, which can realize the rapid switching of two smoke outlet heights, can flexibly switch the smoke outlet position, and thus can connect different downstream equipment.

[0026] The smoke outlet wheel set 100 includes a low-position smoke outlet wheel 10 and a high-position smoke outlet wheel set 20. Among them, a plurality of U-shaped material grooves are arranged on the low-position smoke outlet wheel 10. The width of the material groove is slightly larger than the diameter of a single material, and negative pressure holes are processed in each material groove. After the equipment is started, negative pressure is generated in the negative pressure holes to adsorb the materials in the material grooves. As the low-position smoke outlet wheel 10 rotates, the materials are taken away and transferred downward. And air distribution grooves are opened in the corresponding areas on the air distribution seat inside the drum. Thus, when the drum rotates, there is negative pressure in some areas of the material groove and no negative pressure in some areas, so as to stably dock and transfer the materials. And the subsequent other drums in this wheel set also transfer materials in this form, which is a well-known drum transfer method in the art and will not be elaborated later.

[0027] The high-position smoke outlet wheel set 20 is arranged above the low-position smoke outlet wheel 10, and the negative pressure state of the high-position smoke outlet wheel set 20 can be controlled independently. Among them, the fact that the negative pressure state of the high-position smoke outlet wheel set 20 can be controlled independently means that the negative pressure in the drum of the high-position smoke outlet wheel set 20 can be controlled independently. When the low-position smoke outlet wheel 10 is running normally, the negative pressure of the high-position smoke outlet wheel set 20 can be independently closed or opened.

[0028] It can be understood that the separate control of the negative pressure state of the high-position smoke outlet wheel set 20 can be achieved by connecting the high-position smoke outlet wheel set 20 to a set of negative pressure gas source equipment separately and controlling this separate negative pressure gas source equipment to control the negative pressure state of the high-position smoke outlet wheel set 20 alone; it can also be that the high-position smoke outlet wheel set 20 shares a set of negative pressure gas source equipment with the low-position smoke outlet wheel 10, but a control switch is provided on the negative pressure gas path of the high-position smoke outlet wheel set 20, so as to control the on-off of the negative pressure gas path through the control switch, thereby achieving the separate control of the negative pressure state of the high-position smoke outlet wheel set 20. That is to say, as long as the negative pressure state of the high-position smoke outlet wheel set 20 can be controlled separately, any achievable control form can be adopted.

[0029] The high-position smoke outlet wheel set 20 includes a transmission wheel 21 and a high-position smoke outlet wheel 22 arranged in sequence. The transmission wheel 21 is docked with the low-position smoke outlet wheel 10, and the discharging position of the high-position smoke outlet wheel 22 is higher than the discharging position of the low-position smoke outlet wheel 10.

[0030] The smoke outlet wheel set 100 has a low-position smoke outlet mode and a high-position smoke outlet mode. In the low-position smoke outlet mode, the material is output through the low-position smoke outlet wheel 10; in the high-position smoke outlet mode, the material is transferred from the low-position smoke outlet wheel 10 to the high-position smoke outlet wheel set 20 and output through the high-position smoke outlet wheel 22. Among them, in the low-position smoke outlet mode, the negative pressure in the high-position smoke outlet wheel set 20 can be in a cut-off state, and at this time, the high-position smoke outlet wheel set 20 will not affect the normal low-position smoke outlet of the low-position smoke outlet wheel 10. In the high-position smoke outlet mode, the negative pressure in the high-position smoke outlet wheel set 20 is in a conducting state. At this time, the material of the low-position smoke outlet wheel 10 will be transferred to the transmission wheel 21, and then transferred to the high-position smoke outlet wheel 22 through the transmission wheel 21, and the high-position smoke outlet is carried out by the high-position smoke outlet wheel 22.

[0031] It can be understood that existing tobacco production equipment usually can only smoke at one position. With the continuous upgrading or technical transformation of the equipment on the cigarette factory production line, downstream equipment has put forward new requirements for the height of smoking. In addition, with the expansion of the production scale or the optimization of the production process in the cigarette factory, the layout of the workshop equipment may need to be re-planned. Therefore, when the position of the tobacco production equipment changes, in order to maintain a reasonable spatial relationship and production connection with the surrounding equipment, it is necessary to frequently adjust the height of the smoking position to maintain the coordinated operation of the overall production line and the stability of product quality. At present, in order to achieve connection with downstream equipment, it is usually to carry out an overall transformation of the tobacco production equipment and replace and change the parts at the smoking position of the tobacco production equipment, which not only requires shutting down the equipment and affecting production efficiency, but also requires a large amount of human and material costs.

[0032] In the smoke outlet wheel set 100 provided in this embodiment, the high-position smoke outlet wheel set 20 is provided, and the high-position smoke outlet wheel set 20 can be independently controlled in a negative pressure state, with the function of quickly realizing high / low position switching, enhancing the interchangeability between tobacco production equipment, and effectively reducing the types of parts. When changing the high / low position, the number of parts to be replaced is minimized to the greatest extent, the working time is greatly shortened, and thus the production operation efficiency of the tobacco factory is comprehensively improved, bringing higher flexibility and convenience to the production of the tobacco factory.

[0033] Among them, the high-position smoke outlet wheel set 20 can also be controlled by a separate motor, and only when needed, the transmission wheel 21 and the high-position smoke outlet wheel 22 are controlled to rotate and operate.

[0034] Preferably, in one embodiment, along the rotation direction of the low-position smoke outlet wheel 10, the low-position smoke outlet wheel 10 successively has a feeding position 11, a docking position 12, and a discharging position 13, and the transmission wheel 21 is arranged at the docking position 12 of the low-position smoke outlet wheel 10. That is to say, the transmission wheel 21 is arranged in the area between the feeding position 11 and the discharging position 13 of the low-position smoke outlet wheel 10. By arranging the transmission wheel 21 at the docking position 12 of the low-position smoke outlet wheel 10, the high-position smoke outlet wheel set 20 can have more functions, and the high-position smoke outlet wheel set 20 can be controlled according to requirements to realize more functional roles.

[0035] Preferably, in one embodiment, a positive pressure blowing structure is provided at the air distribution seat of the low-position smoke outlet wheel 10 corresponding to the docking position 12 of the low-position smoke outlet wheel 10. By providing the positive pressure blowing structure at the docking position 12 of the low-position smoke outlet wheel 10, part of the material to be sampled can be blown towards the transfer wheel 21 in the low-position smoke outlet mode, enabling the high-position smoke outlet wheel group 20 to achieve the sampling function. That is to say, in this embodiment, the high-position smoke outlet wheel group 20 is not only used for high-position smoke outlet but also for sampling in the low-position smoke outlet mode. For example, in the low-position smoke outlet mode, the low-position smoke outlet wheel 10 acts as the smoke outlet wheel, responsible for outputting cigarette sticks; the transfer wheel 21 undertakes the task of transferring cigarette sticks; and the high-position smoke outlet wheel 22 is the sampling wheel, used to provide sampling cigarette sticks. During the process of transferring cigarette sticks by the transfer wheel 21 and the high-position smoke outlet wheel 22, the required negative pressure suction is controlled separately. When the system does not receive a sampling signal, the switch for controlling the negative pressure state of the high-position smoke outlet wheel group 20 is in the closed state. At this time, the negative pressure of the transfer wheel 21 and the high-position smoke outlet wheel 22 is also turned off, and the cigarette sticks are directly conveyed by the low-position smoke outlet wheel 10 to the conveying device 300 and then continue to be transferred to downstream equipment. Once the system receives a sampling signal, the switch for controlling the negative pressure state of the high-position smoke outlet wheel group 20 is immediately opened, and the transfer wheel 21 and the high-position smoke outlet wheel 22 are connected to the negative pressure. At the same time, the high-speed solenoid valve on the air distribution seat of the low-position smoke outlet wheel 10 is activated to blow the cigarette sticks to be sampled upwards. The transfer wheel 21 accurately receives the cigarette sticks and completes the output work of the sampling cigarette sticks through the high-position smoke outlet wheel 22. And in the low-position smoke outlet mode, a sampling box can be provided at the discharging position of the high-position smoke outlet wheel 22. Among them, the specific structure of the positive pressure blowing structure provided at the docking position 12 of the low-position smoke outlet wheel 10 can refer to the corresponding structure on the rejection wheel of the cigarette making and tipping machine or other drum structures that can achieve instantaneous positive pressure blowing, which will not be elaborated here. Through this structural design, in the low-position smoke outlet mode, the high-position smoke outlet wheel group 20 still has corresponding functional roles, and no additional sampling structure needs to be set in the equipment, improving the compactness and integration of the equipment.

[0036] Among them, sampling through the high-position smoke outlet wheel set 20 is mainly to verify the operation of the equipment. For example, when the equipment is operating normally, through the cooperation between the detection wheel and the rejection wheel in the equipment, defective products detected during the transfer process are rejected, and qualified products are transferred backward through the low-position smoke outlet wheel 10. At this time, the high-position smoke outlet wheel set 20 does not sample the products. When it is necessary to sample and detect the quality, the high-position smoke outlet wheel set 20 can be turned on to collect samples through the high-position smoke outlet wheel set 20. The collected samples are mainly used to check the quality of the products or to check whether the rejection of defective products by the rejection wheel in the equipment is accurate. For example, through system settings, the high-position smoke outlet wheel set 20 samples defective cigarette sticks with certain appearance quality defects. If the sampled products are the set waste cigarette types, it means that the equipment rejection and sampling systems are both accurate, thereby verifying the operation accuracy of the equipment. If the sampled products are not the required products, it indicates that the rejection is inaccurate, which means that the equipment may cause mis-rejection during operation, rejecting qualified finished products while missing defective products and transporting them to the downstream packaging machine, which will result in a large number of defective products (usually when the packaging machine finds that the defective products are caused by the upstream equipment, all products during a certain period of time will be regarded as defective products). By setting the high-position smoke outlet wheel set 20, self-check sampling can be carried out, which can better ensure the reliability and accuracy of the equipment operation and avoid the generation of a large number of defective products during the production process.

[0037] Preferably, in an embodiment, along the rotation direction of the transfer wheel 21, the transfer wheel 21 sequentially has a feeding position 211, a sampling position 212, and a discharging position 213; the docking position 12 of the feeding position 211 of the transfer wheel 21 is opposite to the low-position smoke outlet wheel 10.

[0038] Preferably, in one embodiment, a positive pressure blowing structure is provided on the air distribution seat of the transfer wheel 21 corresponding to the sampling position 212 of the transfer wheel 21. By providing the positive pressure blowing structure at the sampling position 212 of the transfer wheel 21, some of the materials to be sampled can be blown outwards during the high-position smoke discharging mode, so as to achieve the sampling function. That is to say, in this embodiment, the high-position smoke discharging wheel set 20 can also achieve the sampling function during the high-position smoke discharging mode. For example, during the high-position smoke discharging mode, the conveying device 300 is installed on the upper side. In this mode, the low-position smoke discharging wheel 10 undertakes the function of the transfer wheel and is responsible for transferring cigarette sticks; the transfer wheel 21 serves as the sampling wheel for screening out the cigarette sticks to be sampled; and the high-position smoke discharging wheel 22 plays the role of the smoke discharging wheel to output the finished cigarette sticks. The switch for controlling the negative pressure state of the high-position smoke discharging wheel set 20 is turned on immediately when the equipment starts and turned off immediately when the equipment stops. When the system does not receive a sampling signal, the cigarette sticks are sequentially transferred from the low-position smoke discharging wheel 10 to the transfer wheel 21 and finally output by the high-position smoke discharging wheel 22, and are smoothly conveyed to the downstream equipment via the conveying device 300 after being moved upwards. Once the system receives a sampling signal, the high-speed solenoid valve on the air distribution seat of the transfer wheel 21 is quickly activated to directly blow out the cigarette sticks to be sampled and accurately drop them into the sampling box. Similarly, for the specific structure of the positive pressure blowing structure provided at the sampling position 212 of the transfer wheel 21, reference can be made to the corresponding structure on the rejection wheel of the cigarette making and tipping machine or other drum wheels that can achieve instantaneous positive pressure blowing, which will not be elaborated here. Preferably, in one embodiment, a control switch 23 is provided on the negative pressure air path of the high-position smoke discharging wheel set 20, and the control switch 23 is used to control the on-off of the negative pressure air path of the high-position smoke discharging wheel set 20. Among them, the control switch 23 can adopt a mechanical form to block the air flow, or the control switch 23 can also adopt an electrical control form to block the negative pressure, as long as it can achieve the negative pressure control of the high-position smoke discharging wheel set 20.

[0039] Preferably, in one embodiment, the control switch 23 adopts a solenoid valve or a servo motor, so as to have a faster response speed and ensure the accuracy and reliability of negative pressure control.

[0040] It should be noted that the specific number of the transfer wheels 21 can be selected according to actual needs. For example, the number of the transfer wheels 21 can be increased, so as to increase the smoke discharging height of the high-position smoke discharging wheel 22 to adapt to downstream equipment with a higher position. In order to ensure the correct smoke discharging direction of the high-position smoke discharging wheel 22, it is preferably to increase or decrease the transfer wheels 21 in groups.

[0041] When the smoke outlet wheel set 100 is in different high / low position smoke outlet modes, the low position smoke outlet wheel 10, the transfer wheel 21, and the high position smoke outlet wheel 22 respectively undertake different functions (such as smoke outlet wheel, transfer wheel, sampling wheel). Through this distribution method and corresponding negative pressure control and cigarette conveying control methods, the smoothness and accuracy of cigarette transfer, sampling, and output in different modes can be ensured. And when performing the high / low position switching operation, this group of drums and their air distribution seats do not need to be replaced. Only the output device 300 in the equipment and some parts related to sampling need to be replaced, and no addition or subtraction operations need to be performed on the box body of the high position smoke outlet part. This design has significant advantages. On the one hand, during the high / low position switching process, large lifting equipment such as overhead cranes is not required, reducing the complexity of operation and the dependence on large equipment. On the other hand, the number and types of parts to be replaced are greatly reduced, greatly shortening the operation time, enabling the high / low position switching to be completed quickly and conveniently, and effectively improving the overall work efficiency, providing a strong guarantee for the efficient operation of the production process.

[0042] Meanwhile, in an embodiment, a tobacco production device 1000 is further provided, which applies the smoke outlet wheel set 100. The smoke outlet wheel set 100 is arranged on the main wall panel 200 of the tobacco production device 1000, and a conveying device 300 is arranged at the rear side of the smoke outlet wheel set 100.

[0043] Specifically, in an embodiment, the tobacco production device 1000 is a filter rod making and tipping machine.

[0044] Specifically, in an embodiment, the conveying device 300 is a belt conveying device.

[0045] Preferably, in an embodiment, a first installation position 210 and a second installation position 220 are arranged on the main wall panel 200. The first installation position 210 is located at the discharging position 13 of the low position smoke outlet wheel 10, and the second installation position 220 is located at the discharging position of the high position smoke outlet wheel 22. The conveying device 300 is arranged at the first installation position 210 or the second installation position 220.

[0046] Among them, in an embodiment, when in the low position smoke outlet mode, the conveying device 300 is arranged at the first installation position 210, and a sampling box can be arranged at the second installation position 220. When in the high position smoke outlet mode, the conveying device 300 is arranged at the second installation position 220, and a sampling box can be arranged at the first installation position 210.

[0047] Preferably, in one embodiment, the control switch 23 for controlling the on / off of the negative pressure air path of the high-position smoke outlet drum group 20 is provided on the main wall panel 200. Specifically, the main wall panel 200 can block the air flow by mechanical means, such as through a specific mechanical valve device, or adopt an electrical method, using electrical components such as solenoid valves to control the on / off of the circuit, so as to cut off the negative pressure required for the drum to operate. For example, the negative pressure of the high-position smoke outlet drum group 20 can be precisely controlled by an internal solenoid valve or a servo motor.

[0048] The low-position smoke outlet drum 10, the transfer drum 21, the high-position smoke outlet drum 22 and their air distribution seats in the smoke outlet drum group 100 have extremely high versatility. When performing the high / low position switching operation, this group of drums and their air distribution seats do not need to be replaced. Only the conveying device 300 and some parts related to sampling need to be replaced, and no addition or subtraction operations need to be performed on the box body of the high-position smoke outlet part, reducing the complexity of the equipment structure and the switching cost.

[0049] The tobacco production equipment 1000 adopting the design of the smoke outlet drum group 100 can bring obvious advantages: 1. Cost reduction Procurement cost: Since the number and types of parts to be replaced are reduced, the cost of purchasing parts is correspondingly reduced. There is no need to pay for a large number of different types of parts, and at the same time, the inventory management cost is also reduced.

[0050] Maintenance cost: Fewer parts mean lower maintenance workload and cost. During the equipment maintenance process, the work of inspecting, repairing and replacing parts becomes simpler, reducing the work intensity of maintenance personnel and the time cost required for maintenance, and also reducing the losses caused by production stagnation due to equipment failures.

[0051] 2. Improved stability and reliability Reduced failure points: The reduction in the number of parts means that the structure of the equipment is more concise, and the potential failure points are correspondingly reduced. Fewer parts mean a lower probability of problems such as wear, looseness, and damage, thus improving the overall stability and reliability of the equipment, reducing the risk of equipment failure, and improving the continuity of production and the stability of product quality.

[0052] Better compatibility: The general design of the drums and their air distribution seats makes the compatibility between various components better. When switching between high and low positions, since the same general components are used, the cooperation between components is closer and more stable, reducing problems caused by component mismatches and further improving the reliability of the equipment.

[0053] 3. Enhanced flexibility and adaptability Quick response to requirements: The quick and convenient high-low position switching function enables the equipment to more flexibly adapt to different production requirements and process requirements. During the production process, if it is necessary to adjust the high and low positions according to product specifications, production plans or customer needs, the equipment can quickly complete the switching and quickly enter the new production mode, improving the flexibility of production and the response ability to market changes.

[0054] Convenient for upgrading and transformation: This design facilitates the future upgrading and transformation of the equipment. Since the main components are universal, when upgrading or transforming the equipment, it is easier to integrate new technologies or functional modules without making large-scale changes to the entire equipment structure, reducing the difficulty and cost of equipment upgrading and transformation.

[0055] 4. Enhance safety Simplify the operation process: The complex part replacement and the use of large equipment are reduced, and the operation process becomes more simple and clear. When the operator performs the high-low position switching, the risk factors faced are correspondingly reduced, reducing the possibility of safety accidents caused by operation errors or equipment failures.

[0056] Reduce mechanical risks: Fewer parts mean that the mechanical moving parts during equipment operation are relatively reduced, thus reducing the chance of operators coming into contact with moving parts and reducing the risk of safety accidents such as mechanical injuries, improving the work safety of operators.

[0057] The above are only the implementation manners of the present invention. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the inventive concept of the present invention, but these all belong to the protection scope of the present invention.
