Description

Technical Field

[0001] This invention relates to a non-compression, high-density conveying device for irregularly shaped smoke, belonging to the field of logistics and transportation technology. Background Technology

[0002] In the current tobacco industry, the sales volume of irregularly shaped cigarettes is increasing daily, and the production and packaging of these cigarettes are becoming increasingly personalized. This has resulted in a wide variety of sizes and specifications for irregularly shaped cigarette cartons, placing enormous pressure on the sorting and production of these cigarettes. Sorting equipment must not only handle the ever-increasing production volume but also be compatible with sorting more cartons of cigarettes with varying shapes. Furthermore, because irregularly shaped cigarettes are relatively expensive, customers have stricter requirements regarding the integrity of the cigarette cartons' appearance.

[0003] Under the existing sorting method for irregularly shaped cigarettes, the sorting equipment is difficult to integrate due to the significant differences in the cigarette's shape, so most of the sorting is done manually. Manual sorting is not only inefficient and significantly increases the production cycle, but it also introduces a certain error rate.

[0004] Because most tobacco retailers allow relatively small order quantities of irregularly shaped cigarettes, the effective utilization rate of sorting conveyor belts is low during sorting production tasks, thus limiting the production efficiency of sorting equipment.

[0005] In current sorting equipment, the loose cigarette packs ejected from the cigarette bin are combined into a single unit by a stopper mechanism that accumulates the cigarette packs on the conveyor belt. During this pressing process, the cigarette packs no longer follow the conveyor belt forward due to the stopper's obstruction. The cigarette packs are continuously rubbed by the conveyor belt until the last loose cigarette pack arrives and is tightly joined together. Therefore, the pressing process causes some wear or damage to the shape of the cigarette packs due to compression and friction. Furthermore, cigarette packs often become scattered and cannot be regularly joined together, leading to downtime and affecting production efficiency. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a non-extrusion compaction conveying device for irregularly shaped cigarettes. This device effectively solves the problems of damage caused by the accumulation and compression of irregularly shaped cigarettes during the blocking-type compaction process, as well as damage caused by prolonged friction with the conveyor belt. It also effectively improves the conveying efficiency of the conveyor belt and effectively solves the problem of scattered and lumped cigarettes during the compaction process, thereby improving sorting efficiency.

[0007] The present invention is achieved through the following technical solutions.

[0008] The present invention provides a non-compression, high-density conveying device for irregularly shaped cigarettes, comprising a main belt conveyor; the front stage of the main belt conveyor is connected to the cigarette bin, and the rear stage of the main belt conveyor is connected to a pressing belt conveyor and a buffer belt conveyor in sequence; the conveying speed of the pressing belt conveyor has two working states, one is slower than the conveying speed of the main belt conveyor, and the other is the same as the conveying speed of the buffer belt conveyor.

[0009] There is a reverse step between the main conveyor belt and the single-belt press, meaning that the upper surface of the single-belt press is higher than the upper surface of the main conveyor belt.

[0010] The conveying speeds of the single-belt press and the buffer belt conveyor are the same.

[0011] The main conveyor belt is driven by a main conveyor belt drive motor, which is a three-phase asynchronous motor.

[0012] The single-belt press is driven by a single-belt drive motor, which is a servo motor.

[0013] The buffer belt conveyor is driven by a buffer belt drive motor, which is a three-phase asynchronous motor.

[0014] The conveying speed of the main belt conveyor is 0.9 m / s.

[0015] The conveying speed of the buffer belt conveyor is 1 m / s.

[0016] The conveying speed of the single belt conveyor is 0.3 to 1 m / s.

[0017] The beneficial effects of this invention are as follows: by controlling the variable speed movement of the pressing belt conveyor, scattered cigarette packs are pressed into packs without compression, avoiding damage caused by compression and long-term friction between the cigarette packs and the pressing belt during the blocking pressing process; it breaks through the traditional single-customer conveying method and realizes a highly efficient and dense conveying method for multiple customers with a single pack, greatly improving the transmission efficiency of the conveyor belt; it increases the number of different types of cigarettes that can be centrally sorted through the cigarette bin, reducing the workload and error rate of manual picking by sorting staff.

Detailed Implementation

[0021] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0022] The first embodiment of the present invention relates to, for example Figure 1 , Figure 2 The device shown is a non-compression, high-density conveying device for irregularly shaped smoke, including a main conveyor belt 1; the main conveyor belt 1 is connected to the smoke chamber 9 in the front stage, and the main conveyor belt 1 is connected to the compression conveyor belt 2 and the buffer conveyor belt 3 in sequence in the rear stage; the compression conveyor belt 2 has two working states: one is slower than the conveying speed of the main conveyor belt 1, and the other is the same as the conveying speed of the buffer conveyor belt 3.

[0023] In operation, based on the order information from tobacco retailers, cigarette bin 9 continuously and orderly ejects cartons of cigarettes corresponding to the customer's brand onto the main conveyor belt 1, with intervals between them. The main conveyor belt 1 then transports the loose cartons of cigarettes from the order at high speed to the pressing conveyor belt 2. At this time, the pressing conveyor belt 2 operates at low speed, and the speed difference between the main conveyor belt 1 and the pressing conveyor belt 2 eliminates the gaps between the loose cartons of cigarettes in the order, thus combining the loose cartons of cigarettes into a whole without compression, which is called pressing. When the last carton of cigarettes in the order has come together and completely entered the pressing conveyor belt 2, it means that the pressing of the order is complete. After the loose cartons of cigarettes are pressed, the pressing conveyor belt will switch to high speed, the same as the buffer conveyor belt 3, to transport the pressed cartons of cigarettes to the buffer conveyor belt 3 at high speed and seamlessly.

[0024] The second embodiment of the present invention is largely the same as the first embodiment, except that there is a reverse step between the main conveyor belt 1 and the single-press conveyor belt 2, that is, the upper surface of the single-press conveyor belt 2 is higher than the upper surface of the main conveyor belt 1. Therefore, the posture of the cigarette packs being conveyed at high speed can be effectively corrected when they come into contact with the low-speed single-press conveyor belt 2.

[0025] Furthermore, the conveying speeds of the single-belt conveyor 2 and the buffer belt conveyor 3 are the same.

[0026] Furthermore, the main conveyor belt 1 is driven by the main conveyor belt drive motor 4, which is a three-phase asynchronous motor.

[0027] Furthermore, the single-belt press 2 is driven by the single-belt press drive motor 5, which is a servo motor.

[0028] Furthermore, the buffer belt conveyor 3 is driven by the buffer belt drive motor 6, which is a three-phase asynchronous motor.

[0029] The third embodiment of the present invention is largely the same as the first embodiment, except that the conveying speed of the main belt conveyor 1 is 0.9 m / s.

[0030] Furthermore, the conveying speed of the buffer belt conveyor 3 is 1 m / s.

[0031] Furthermore, the conveying speed of the single belt conveyor 2 is 0.3 to 1 m / s.

[0032] Therefore, this invention is mainly applied in the sorting equipment for irregularly shaped cigarette sticks in the tobacco industry. By controlling the variable speed movement of the conveyor belt, the continuous, orderly, and spaced scattered cigarette sticks ejected from the cigarette bin are first squeezed together in an orderly manner to form a whole without compression. Then, the conveyor belt is switched to high-speed operation for dense conveying.
