Description

Technical Field

[0001] This invention relates to the field of cigarette detection and counting technology, and in particular to an automatic cigarette counting device. Background Technology

[0002] With the continuous improvement of quality management systems in the cigarette industry, the precision of cigarette management has been raised to the individual cigarette level. In daily work processes such as quality sampling inspections during cigarette production, finished product testing before leaving the factory, and warehouse inventory checks, it is necessary to conduct precise checks on each cigarette to ensure accurate quantity and batch distinction.

[0003] Currently, there is no dedicated automated cigarette counting equipment in the industry. In practice, manual counting is still the primary method: operators lay the cigarettes to be counted flat on a workbench or hold them by hand and count them visually, recording the quantity manually. When counting hundreds or even thousands of cigarettes, operators need to concentrate for extended periods to repeat the counting action, which is not only extremely labor-intensive and time-consuming, but also highly susceptible to human errors such as omissions and duplicates due to visual fatigue and distraction, making it difficult to consistently guarantee counting accuracy. In addition, cigarettes are prone to congestion and bridging when piled up, disrupting the sampling and counting process and further affecting overall testing efficiency.

[0004] Therefore, there is an urgent need for an automated counting device that can automatically, accurately, and quickly count cigarettes to replace the traditional manual counting method and improve the efficiency and standardization of cigarette testing and sampling. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic cigarette counting device, which solves the technical problem that the cigarette industry currently lacks dedicated automated cigarette counting equipment, and relies on manual counting in actual operation.

[0006] To achieve the above objectives, the present invention provides an automatic cigarette counting device, comprising:

[0007] The housing has a feeding chamber inside, and the housing is provided with an inlet and an outlet communicating with the feeding chamber;

[0008] A flow diversion and guiding assembly is disposed in the feeding chamber. The flow diversion and guiding assembly includes at least two guide plates arranged at intervals in the vertical direction. The guide plates are inclined relative to the horizontal direction, and a feeding gap is formed between the lower end of the guide plate and the inner wall of the housing.

[0009] The anti-blocking feeding assembly includes multiple friction rollers, which are correspondingly arranged with multiple guide plates. Each friction roller is rotatably disposed at the lower end of the corresponding guide plate and extends along the length direction of the lower end of the corresponding guide plate. The outer peripheral surface of the friction roller is at least partially located within the corresponding material drop gap.

[0010] The column counting component is located below the diversion guide component. The column counting component includes multiple passage slots through which cigarette sticks pass one by one, and multiple photoelectric detection elements corresponding to the passage slots.

[0011] A counting display component is disposed in the housing and electrically connected to a plurality of the photoelectric detection elements.

[0012] In some technical solutions, the housing is a funnel-shaped housing that is wider at the top and narrower at the bottom, and the cross-sectional area of ​​the feeding chamber gradually decreases from the feeding port to the array counting component.

[0013] In some technical solutions, at least two guide plates extend downward at an angle from the inner walls of opposite sides of the housing, and the lower ends of two adjacent guide plates are staggered in the vertical direction.

[0014] In some technical solutions, the guide plate is mounted on the housing via an angle adjustment mechanism, which is used to adjust the tilt angle of the guide plate. The angle adjustment mechanism includes a rotating connection, an arc-shaped adjustment groove, and a locking member. One end of the guide plate is rotatably connected to the housing via the rotating connection. The arc-shaped adjustment groove is disposed in the housing. The locking member passes through the arc-shaped adjustment groove and is connected to the guide plate. The locking member is used to lock the guide plate to the housing after the guide plate is adjusted to a preset angle.

[0015] In some technical solutions, the rotating connection part includes a rotating shaft and a shaft hole. The rotating shaft is disposed on the side wall of the housing, the shaft hole is disposed on the guide plate, and the rotating shaft passes through the shaft hole. The arc-shaped adjustment groove extends in an arc shape with the axis of the rotating shaft as the center, and the locking member is a locking bolt or a locking knob.

[0016] In some technical solutions, the anti-blocking dialing component further includes a drive motor and a transmission component. The drive motor is connected to multiple friction rollers via the transmission component, and the transmission component is one of a gear transmission component, a synchronous belt transmission component, or a chain transmission component.

[0017] In some technical solutions, the outer peripheral surface of the friction roller is provided with at least one of the following: a friction layer, spiral ridges, flexible bristles, or circumferential friction protrusions.

[0018] In some technical solutions, the column counting component includes a plurality of partitions spaced laterally, with a passage slot formed between two adjacent partitions.

[0019] In some technical solutions, the width of the passage groove is greater than the outer diameter of a single cigarette but less than the outer contour width of two cigarettes placed side by side.

[0020] In some technical solutions, each of the photoelectric detection devices includes a transmitter and a receiver, which are respectively disposed on both sides of the corresponding passage slot, and a detection optical path is formed between the transmitter and the receiver through the corresponding passage slot.

[0021] Compared to the aforementioned background technology, the automatic cigarette counting device provided by this invention can automatically count cigarettes. After being diverted and conveyed by a guide plate and friction rollers, cigarettes enter multiple passage slots. Each passage slot can separate and arrange the cigarettes, allowing cigarettes in a single passage slot to pass one by one, reducing the risk of missed or incorrect counting caused by multiple cigarettes passing side-by-side or overlapping at the detection position. By cooperating with multiple passage slots and multiple photoelectric detection elements, it can achieve multi-channel parallel counting while ensuring the accuracy of cigarette detection in a single passage slot, avoiding the problem of low efficiency in single-channel counting, thus balancing the accuracy and efficiency of cigarette counting.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to this as well. Figures 1 to 5 This embodiment provides an automatic cigarette counting device, which can be used for cigarette production inspection, quality sampling, inventory verification, or other scenarios that require counting individual cigarettes.

[0033] The automatic cigarette counting device includes a housing 1, a diversion and guiding assembly, an anti-blocking conveying assembly, an alignment and counting assembly, and a counting display assembly 5. The housing 1 has a feeding chamber 11 inside, and is provided with an inlet 12 and an outlet 13 communicating with the feeding chamber 11. The inlet 12 is located at the upper part of the housing 1 so that the cigarettes to be counted are fed into the feeding chamber 11 from above; the outlet 13 is located at the lower part of the housing 1 so that the counted cigarettes are discharged from below.

[0034] The diversion and guiding assembly is disposed within the feeding chamber 11. The diversion and guiding assembly includes at least two guide plates 2 spaced apart along the vertical direction. The guide plates 2 are inclined relative to the horizontal direction, and their upper surfaces form a receiving and guiding surface during the cigarette's descent. A feeding gap is formed between the lower end of the guide plate 2 and the inner wall of the housing 1. After entering the feeding chamber 11, the cigarette can fall onto the upper guide plate 2 and move downwards along it, then continue falling through the corresponding feeding gap to the lower guide plate 2 or the column counting assembly.

[0035] The anti-blocking feeding assembly includes multiple friction rollers 3. These friction rollers 3 are correspondingly arranged with multiple guide plates 2. Each friction roller 3 is rotatably positioned at the lower end of its corresponding guide plate 2 and extends along the length direction of the lower end of the guide plate 2, where the length direction of the lower end of the guide plate 2 can be understood as the extension direction of the lower edge of the guide plate 2. The friction rollers 3 are arranged parallel to the lower ends of their respective guide plates 2, and at least a portion of the outer circumferential surface of each friction roller 3 is located within the corresponding material drop gap. Since cigarettes tend to accumulate or bridge near the material drop gap between the lower end of the guide plate 2 and the inner wall of the housing 1 when falling in a concentrated manner, the friction rollers 3, positioned at this location, can slightly agitate or feed the cigarettes through their own rotation, allowing the cigarettes to continue moving downwards through the material drop gap.

[0036] The counting assembly is positioned below the diversion guide assembly, near the discharge port 13. The counting assembly includes multiple passageways 4 through which cigarettes pass one by one, and multiple photoelectric detection elements corresponding to the passageways 4. The multiple passageways 4 can be arranged side-by-side, each serving as a single path for a cigarette. The structural dimensions of each passageway 4 can be customized according to the outer diameter of the cigarette, allowing a single cigarette to pass through its corresponding passageway 4. The multiple photoelectric detection elements are arranged corresponding to the multiple passageways 4 to detect the passage of cigarettes within their respective passageways 4.

[0037] The counting and display component 5 is mounted on the housing 1 and electrically connected to multiple photoelectric detectors. The counting and display component 5 may include a counter, a display screen, control buttons, a circuit board, or other display and counting module. Each photoelectric detector generates a detection signal when it detects a cigarette passing by. The counting and display component 5 receives the detection signals from multiple photoelectric detectors, counts the quantity, and displays the cumulative quantity or batch quantity.

[0038] In operation, the operator inserts the cigarettes to be counted into the feeding chamber 11 of the housing 1 through the feed inlet 12. Under gravity, the cigarettes pass sequentially through multiple inclined guide plates 2, and are further lowered by friction rollers 3 at the material drop gaps at the lower ends of each guide plate 2. After being diverted, guided, and anti-blocking, the cigarettes enter multiple passage slots 4. Multiple photoelectric detectors detect the cigarettes passing through each passage slot 4, and the counting and display assembly 5 counts and displays the detection signals, thus achieving automatic cigarette counting.

[0039] In some embodiments, the housing 1 is a funnel-shaped housing that is wider at the top and narrower at the bottom, and the cross-sectional area of ​​the feeding chamber 11 gradually decreases from the feeding port 12 toward the array counting components. This structure allows the upper part of the housing 1 to accommodate a certain number of cigarettes, making it convenient for operators to feed multiple cigarettes at once; at the same time, as the feeding chamber 11 gradually contracts downwards, the cigarettes can be gradually guided to the area where the array counting components are located.

[0040] In one specific embodiment, the housing 1 may include a front side plate, a rear side plate, a left side plate, and a right side plate, with at least some of the side plates inclined inward from top to bottom, forming a funnel-like contracting space in the feeding chamber 11. The feeding port 12 may be an open structure, located at the top of the housing 1; the discharging port 13 may be located at the bottom of the housing 1. The gradually contracting structure of the feeding chamber 11, in conjunction with the internal guide plate 2, allows the cigarettes to gradually enter the narrower counting area from a wider feeding area.

[0041] In some embodiments, at least two guide plates 2 extend downward at an angle from the inner walls of opposite sides of the housing 1, and the lower ends of two adjacent guide plates 2 are staggered in the vertical direction. That is, one guide plate 2 can extend from the inner wall of the left side of the housing 1 to the lower right, and the other guide plate 2 can extend from the inner wall of the right side of the housing 1 to the lower left. The two are spaced apart in the vertical direction, and their lower ends are not at the same height.

[0042] In one specific embodiment, multiple guide plates 2 are arranged alternately in the vertical direction. The upper guide plate 2 guides the cigarette to one side of the feeding gap, and the lower guide plate 2 then guides the cigarette to the other side of the feeding gap, thereby forming a downward falling path for the cigarette within the feeding chamber 11. This structure reduces the probability of the cigarette falling directly and in a concentrated manner in the vertical direction, allowing the cigarette to be gradually dispersed during the falling process, which is beneficial for its subsequent entry into the multiple passage slots 4.

[0043] In some embodiments, the guide plate 2 is mounted on the housing 1 via an angle adjustment mechanism, which adjusts the tilt angle of the guide plate 2. The angle adjustment mechanism includes a rotating connection, an arc-shaped adjustment groove, and a locking member. One end of the guide plate 2 is rotatably connected to the housing 1 via the rotating connection. The arc-shaped adjustment groove is disposed in the housing 1, and the locking member passes through the arc-shaped adjustment groove and is connected to the guide plate 2. The locking member can lock the guide plate 2 to the housing 1 after it has been adjusted to a preset angle.

[0044] When it is necessary to adjust the tilt angle of the guide plate 2, loosen the locking element to allow the guide plate 2 to rotate relative to the housing 1 around the rotating connection. As the guide plate 2 rotates, the locking element moves along the arc-shaped adjustment groove. When the guide plate 2 is adjusted to an angle suitable for the current cigarette specification or feeding speed, tighten the locking element to fix the guide plate 2 at that angle position.

[0045] By adjusting the tilt angle of the guide plate 2, the speed at which the cigarette slides down the guide plate 2 and the feeding state at the feeding gap can be changed, thereby adapting to different specifications of cigarettes or different counting speed requirements.

[0046] In some embodiments, the rotating connection includes a rotating shaft and a shaft hole. The rotating shaft is disposed on the side wall of the housing 1, and the shaft hole is disposed in the guide plate 2. The rotating shaft passes through the shaft hole, allowing the guide plate 2 to rotate relative to the housing 1 around the rotating shaft. The arc-shaped adjustment groove extends in an arc shape with the axis of the rotating shaft as its center. The locking element is a locking bolt or a locking knob.

[0047] In one specific embodiment, one end of the guide plate 2 is sleeved on a rotating shaft on the side wall of the housing 1 through a shaft hole, and the other end of the guide plate 2 is connected to a locking member. An arc-shaped adjustment groove is formed on the side wall of the housing 1, and the locking member passes through the arc-shaped adjustment groove and connects to the guide plate 2. When the guide plate 2 rotates around the rotating shaft, the locking member moves along the arc-shaped adjustment groove with the guide plate 2. The center of the arc-shaped adjustment groove is approximately aligned with the axis of the rotating shaft, allowing the locking member to move smoothly during the rotation of the guide plate 2.

[0048] When the locking mechanism uses locking bolts, the side wall of housing 1 and guide plate 2 can be pressed together by nuts or threaded holes to achieve locking. When the locking mechanism uses locking knobs, operators can manually adjust the tightness without tools, improving the convenience of on-site adjustment.

[0049] In some embodiments, the anti-blocking feeding assembly further includes a drive motor and a transmission assembly. The drive motor is connected to a plurality of friction rollers 3 via the transmission assembly. The transmission assembly can be one of a gear transmission assembly, a synchronous belt transmission assembly, or a chain transmission assembly.

[0050] In one specific embodiment, the drive motor is mounted on the outside of the housing 1, and the ends of the friction rollers 3 protrude or extend to the side wall of the housing 1. The drive motor drives multiple friction rollers 3 to rotate synchronously via a synchronous belt and pulleys. The synchronous belt drive structure operates smoothly, making it easy for multiple friction rollers 3 to maintain the same or similar rotational speeds.

[0051] In another specific embodiment, gears are respectively provided at the ends of multiple friction rollers 3, and adjacent friction rollers 3 are driven by gear meshing. The drive motor drives one of the friction rollers 3 to rotate, thereby driving the other friction rollers 3 to rotate. The gear transmission structure is compact and suitable for equipment with limited installation space on the side of the housing 1.

[0052] In another specific embodiment, the transmission assembly includes a sprocket and a chain, and the drive motor drives multiple friction rollers 3 to rotate via the chain drive assembly. The chain drive assembly is suitable for structures with a large spacing between the friction rollers 3.

[0053] The drive motor can be a synchronous motor, a geared motor, or a speed-regulating motor. The drive motor drives the friction roller 3 to rotate at a low speed, so that the friction roller 3 can continuously push the cigarette at the lower end of the guide plate 2 without causing significant impact to the cigarette.

[0054] In some embodiments, the outer peripheral surface of the friction roller 3 is provided with at least one of the following: a friction layer, spiral grooves, flexible bristles, or circumferential friction protrusions. The friction layer can be a rubber layer, a silicone layer, a polyurethane layer, or other material layer with frictional properties that is not prone to damaging the cigarette surface. The spiral grooves can extend spirally along the axial direction of the friction roller 3, generating a slight pushing action on the cigarette along the feeding gap direction when the friction roller 3 rotates. The flexible bristles can be made of nylon bristles, rubber bristles, or other flexible materials, gently pushing the cigarette in a soft contact manner. The circumferential friction protrusions can be spaced apart along the outer periphery of the friction roller 3 to increase the contact friction between the friction roller 3 and the cigarette.

[0055] In one specific embodiment, the outer periphery of the friction roller 3 is covered with a rubber friction layer, and the surface of the rubber friction layer is provided with multiple circumferential friction protrusions. This structure can improve the feeding effect and reduce the risk of damage to the appearance of the cigarette caused by direct contact between the rigid structure and the cigarette.

[0056] In some embodiments, the column counting assembly includes a plurality of partition plates 6 arranged at lateral intervals, with a passage groove 4 formed between two adjacent partition plates 6. The plurality of partition plates 6 can be arranged sequentially along the length direction of the housing 1, forming a channel for cigarettes to pass through between every two adjacent partition plates 6. The length direction of each passage groove 4 can extend along the direction of cigarette falling or the direction of discharge, so that the cigarettes enter the passage groove 4 after being diverted and guided, and their position is detected by photoelectric detection.

[0057] In one specific embodiment, the partition plate 6 is a vertical plate, and its upper end may be provided with an inlet chamfer, rounded corner or inlet slope so that the cigarette can enter between two adjacent partition plates 6.

[0058] In some embodiments, the width of the passage slot 4 is greater than the outer diameter of a single cigarette but less than the outer contour width when two cigarettes are placed side by side. The width of the passage slot 4 refers to the dimension of the passage slot 4 in restricting the two cigarettes from being placed side by side. For conventional cylindrical cigarettes, the width of the passage slot 4 can be slightly larger than the diameter of a single cigarette to allow a single cigarette to pass through smoothly; at the same time, this width is less than the lateral width required when two cigarettes are placed side by side, thereby restricting the two cigarettes from passing through the same passage slot 4 side by side.

[0059] In one specific embodiment, the width of the passage slot 4 can be preset according to the specifications of the cigarettes to be counted. For example, for a cigarette with an outer diameter of D, the width of the passage slot 4 can be greater than D and less than 2D. Furthermore, considering the tolerance of the cigarette's outer diameter and the processing error of the device, the width of the passage slot 4 can be set to D plus a reserved gap, which allows the cigarettes to pass smoothly but is not large enough to accommodate two cigarettes passing side by side.

[0060] With this configuration, each passage slot 4 can form a single-column constraint for cigarettes, reducing the situation where multiple cigarettes simultaneously block the same photoelectric detection element, which helps to improve counting accuracy.

[0061] Furthermore, the partition plates 6 are fixedly installed on the housing 1 via detachable connections such as snap-fit, screw connection, or plug-in. Since the passage slot 4 is formed by two adjacent partition plates 6, the distance between two adjacent partition plates 6 can be changed by adjusting the installation position of the partition plates 6 on the housing 1, thereby changing the size of the passage slot 4, i.e., changing the width of the passage slot 4. Different specifications of cigarettes have different outer diameters. By making the partition plates 6 detachable, the width of the passage slot 4 can be adjusted, thus accommodating different specifications of cigarettes and enabling automatic counting of cigarettes of different specifications, improving the applicability of the automatic cigarette counting device.

[0062] In some embodiments, each photoelectric detection element includes a transmitter and a receiver. The transmitter and receiver are respectively disposed on opposite sides of the corresponding passage slot 4, forming a detection optical path passing through the corresponding passage slot 4 between the transmitter and receiver. The transmitter can be an infrared transmitter, a laser transmitter, or a grating transmitter; the receiver can be an infrared receiver, a laser receiver, or a grating receiver corresponding to the transmitter.

[0063] In one specific embodiment, the transmitting end is installed on one side wall of the passageway 4, and the receiving end is installed on the other side wall of the passageway 4. The detection optical path passes laterally through the passageway 4. When a cigarette passes through the detection optical path, the cigarette blocks the detection optical path, causing a change in the light signal received by the receiving end. The photoelectric detection device then outputs a corresponding detection signal. After receiving the detection signal, the counting and display component 5 counts the cigarettes that have passed through the passageway 4.

[0064] When multiple passage slots 4 are arranged in parallel, multiple photoelectric detection devices can be respectively set up one-to-one with each of the multiple passage slots 4. The detection positions of each photoelectric detection device can be located at the same height, or they can be appropriately staggered according to the structure of the passage slot 4. The output signals of each photoelectric detection device can be connected to the counting display component 5, and the counting display component 5 can accumulate and count the multiple signals.

[0065] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0066] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the present invention.
