Description

Technical Field

[0001] This invention relates to the field of cigarette conveying technology, and in particular to a cigarette anti-congestion mechanism and its control method. Background Technology

[0002] In the tobacco product manufacturing process, cigarette cartons are an intermediate form in the finished cigarette packaging process and need to be transported to downstream sealing equipment for further processing. After the cigarette packs are sealed at the packaging station, they are formed into cigarette cartons. The cigarette cartons are then transported and turned by two conveyor mechanisms extending perpendicularly to each other (such as conveyor belt assemblies and lifting belt assemblies) before entering the elevator, and then being transported to the sealing machine by the elevator.

[0003] During the process of transporting cigarette packs to the downstream sealing equipment, the overall work efficiency is limited by factors such as the performance and operating rhythm of the downstream sealing equipment. When the sealing equipment at the far end of the lifting belt assembly malfunctions, cigarette packs are prone to accumulate and become congested at the near end of the lifting belt assembly, that is, in the intersection area of ​​the lifting belt assembly and the conveyor belt assembly. If the operators do not handle it in time, it will affect the continuity of production and capacity.

[0004] Therefore, there is an urgent need for a mechanism and control method to prevent cigarette pack congestion and solve the above-mentioned technical problems. Summary of the Invention

[0008] In some embodiments, the transfer assembly includes: a support member disposed between the lifting belt assembly and the guide assembly along a second direction; the second direction being a vertical direction; in the second direction, the support member at least partially protrudes from the upper side of the lifting belt assembly; a support member rotatably connected to the support member; the support member being in an inclined state allows the conveyor belt assembly to dock with the lifting belt assembly; the support member being in a horizontal state allows the conveyor belt assembly to dock with the guide assembly; and a drive assembly drivenly connected to the support member; the drive assembly being at least partially movable along the second direction to drive the support member to be in an inclined state or a horizontal state.

[0009] In some embodiments, the drive assembly includes: a connector, a first connecting shaft, a second connecting shaft, and a first drive member; the connector is disposed on the side of the support member opposite to the support member; the first connecting shaft passes through one end of the connector and is rotatably connected to both the connector and the support member; the second connecting shaft passes through the other end of the connector and is rotatably connected to both the connector and the support member; the first drive member is disposed along the second direction and connected to the end of the second connecting shaft away from the support member; the first drive member is coupled to the control assembly and is capable of driving the second connecting shaft to move along the second direction, so that the support member is in an inclined state or in a horizontal state.

[0010] In some embodiments, the blocking assembly includes: a blocking member and a second driving member connected to each other; the second driving member is coupled to the control assembly and is capable of driving the blocking member to move along a third direction, so that the blocking member can block the cigarette strip on the conveyor belt assembly from moving along a first direction; the third direction is the extension direction of the lifting belt assembly.

[0011] In some embodiments, the guide assembly includes: a guide housing and a pusher assembly; the guide housing includes an arcuate portion and an outlet portion; the opening direction of the upper end of the arcuate portion is parallel to the first direction, and the opening direction of the lower end is parallel to the second direction; the second direction is a vertical direction; the outlet portion is connected to the lower end of the arcuate portion; the opening of the outlet portion is positioned directly opposite the sealing platform; the transfer assembly can change its own posture to align the conveyor belt assembly with the upper end of the arcuate portion; the cigarette pack can enter the arcuate portion through the conveyor belt assembly, pass through the arcuate portion, and be discharged to the sealing platform through the outlet portion; the pusher assembly is disposed at the outlet portion and can push the cigarette pack discharged from the outlet portion to the sealing platform along the first direction.

[0012] On the other hand, the present invention provides a control method for a cigarette pack anti-congestion mechanism; this control method is applied to the cigarette pack anti-congestion mechanism described in any of the above embodiments; the cigarette pack anti-congestion mechanism includes: S100, determining the conveying state of the lifting belt assembly; when the conveying state of the lifting belt assembly is congested, the blocking component operates to block the movement of the cigarette packs on the conveying belt assembly, and simultaneously changes the posture of the transfer assembly to a horizontal state so that the conveying belt assembly docks with the guide assembly; then, the blocking component resets, stopping the blocking of the movement of the cigarette packs on the conveying belt assembly; S200, determining the conveying state of the lifting belt assembly; when the conveying state of the lifting belt assembly is non-congested, the blocking component operates to block the movement of the cigarette packs on the conveying belt assembly, and simultaneously changes the posture of the transfer assembly to an inclined state so that the conveying belt assembly docks with the lifting belt assembly; then, the blocking component resets, stopping the blocking of the movement of the cigarette packs on the conveying belt assembly.

[0013] In some embodiments, step S100 includes: S101, defining the normal passage time of the cigarette pack on the lifting belt assembly as T0, and obtaining the actual passage time T1 of the cigarette pack on the lifting belt assembly; S102, the difference between T0 and T1 is ΔT, and determining the conveying state of the lifting belt assembly based on the relationship between ΔT and a preset congestion threshold ΔT1; when ΔT > ΔT1, the conveying state of the lifting belt assembly is a congested state; S103, when the conveying state of the lifting belt assembly is a congested state, the blocking component operates, and simultaneously changes the posture of the transfer assembly to a horizontal state so that the conveying belt assembly docks with the guide assembly; when the posture of the transfer assembly changes to a horizontal state, the blocking component resets.

[0014] In some embodiments, step S200 includes: S201, determining the conveying state of the lifting belt assembly based on the relationship between ΔT and a preset congestion threshold ΔT1; when ΔT < ΔT1, the conveying state of the lifting belt assembly is a non-congested state; S202, when the conveying state of the lifting belt assembly is a non-congested state, the blocking component operates, and simultaneously changes the posture of the transfer assembly to an inclined state so that the conveying belt assembly docks with the lifting belt assembly; when the posture of the transfer assembly changes to an inclined state, the blocking component resets.

[0015] In some embodiments, the difference ΔT is calculated as follows: First, the actual passage time T1 of the cigarette pack on the lifting belt assembly is obtained and multiple sets are continuously recorded; then, the mean of the multiple passage times T1 is calculated to obtain the average value. Finally, calculate the average value. The difference between T0 and T0 is ΔT.

[0016] In some embodiments, after step S300, the cigarette pack anti-congestion mechanism control method further includes: S400, acquiring the status information of the cigarette pack on the transfer assembly; adjusting the posture of the transfer assembly to a horizontal or vertical state according to the status information of the cigarette pack.

[0017] The beneficial effects of this invention are:

[0018] On one hand, the present invention provides a cigarette pack anti-congestion mechanism, which includes a blocking component at one end of the conveyor belt assembly that connects with the lifting belt assembly, which can prevent the cigarette packs on the conveyor belt assembly from moving in a first direction; a guide assembly on the side of the lifting belt assembly away from the conveyor belt assembly that guides the cigarette packs on the conveyor belt assembly to the sealing table; a transfer assembly between the lifting belt assembly and the guide assembly that can connect the conveyor belt assembly and the guide assembly by changing its own posture; and a control component coupled to the blocking component and the transfer assembly respectively. The control component can control the operating state of the blocking component and the posture of the transfer assembly according to the congestion of the lifting belt assembly. This ensures that when the lifting belt assembly is operating normally, i.e., without congestion, the control component does not control the operation of the blocking component or the change in the posture of the transfer assembly. At this time, the conveyor belt assembly and the lifting belt assembly are normally connected, and the cigarette packs can move normally from the conveyor belt assembly to the lifting belt assembly. When the lifting belt assembly becomes congested, the control component controls the blocking component to operate, preventing the cigarette packs on the conveyor belt assembly from continuing to move onto the lifting belt assembly, thus avoiding further congestion. At the same time, it controls the change in posture of the transfer assembly, allowing the conveyor belt assembly to connect with the guide assembly. The transfer assembly acts as a bridge. After the posture of the transfer assembly changes (i.e., after the conveyor belt assembly connects with the guide assembly), the control component controls the blocking component to reset, allowing the cigarette packs on the conveyor belt assembly to resume movement and be able to move through the transfer assembly to the guide assembly, and then be guided by the guide assembly to the sealing platform. During the transport of cigarette packs, the cooperation of the blocking components, transfer components, and guiding components ensures that the cigarette pack transport path bypasses the lifting belt assembly when congestion occurs, preventing congestion at the intersection of the lifting belt assembly and the conveyor belt assembly. This also alleviates congestion on the lifting belt assembly. Throughout the entire cigarette pack transport process, no downtime maintenance is required, improving transport efficiency and ensuring production continuity and capacity.

[0019] On the other hand, the present invention provides a control method for a cigarette pack anti-congestion mechanism. This control method has all the technical features of the cigarette pack anti-congestion mechanism described in any of the embodiments above, and its beneficial effects are the same as those of the cigarette pack anti-congestion mechanism described above, and will not be repeated here. Furthermore, using the above control method to control the cigarette pack anti-congestion mechanism can standardize and streamline the cigarette pack transportation process and the handling of congestion during transportation. This avoids redundant or erroneous operations by staff when congestion occurs during cigarette pack transportation, improves the efficiency of staff in using the above-mentioned cigarette pack anti-congestion mechanism, speeds up the handling of cigarette pack congestion, and ensures production continuity and capacity.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0034] On the one hand, such as Figure 1 As shown, this embodiment provides a cigarette pack anti-congestion mechanism to prevent cigarette packs 7 from congesting at the intersection of the conveyor belt assembly 1 and the lifting belt assembly 2. The lifting belt assembly 2 is arranged perpendicular to and connected to the conveyor belt assembly 1. It is easy to understand that "connection" here does not mean that the lifting belt assembly 2 and the conveyor belt assembly 1 are directly opposite and in contact, but rather that the lifting belt assembly 2 and the conveyor belt assembly 1 are directly opposite and flush, without contact, but the cigarette packs 7 can move smoothly from one to the other. This cigarette pack anti-congestion mechanism includes a blocking component 3, a guiding component 6, a transferring component 5, and a control component.

[0035] Combination Figure 1 , Figure 2 , Figure 3As shown, the aforementioned blocking component 3 is disposed on the conveyor belt assembly 1 and located at the end where the conveyor belt assembly 1 and the lifting belt assembly 2 are connected. The blocking component 3 is, for example, mounted on the belt mounting bracket of the conveyor belt assembly 1. The blocking component 3 can prevent the cigarette pack 7 on the conveyor belt assembly 1 from moving along the first direction X1, where the first direction X1 is the extending direction of the conveyor belt assembly 1.

[0036] The aforementioned guide assembly 6 is disposed on the side of the lifting belt assembly 2 opposite to the conveyor belt assembly 1, and is located above the sealing platform 4. The sealing platform 4 here refers to the table surface of the sealing equipment. The guide assembly 6 is positioned directly opposite the output end of the conveyor belt assembly 1, and is used to guide the cigarette packs 7 on the conveyor belt assembly 1 to the sealing platform 4.

[0037] The aforementioned transfer assembly 5 is positioned between the lifting belt assembly 2 and the guide assembly 6. This transfer assembly 5 can connect the conveyor belt assembly 1 and the guide assembly 6 by changing its own posture. It is easy to understand that when the transfer assembly 5 is in its initial posture, the conveyor belt assembly 1 is not connected to the guide assembly 6, and the conveyor belt assembly 1 is normally connected to the lifting belt assembly 2, allowing the cigarette pack 7 to move normally from the conveyor belt assembly 1 to the lifting belt assembly 2. Furthermore, the aforementioned "connection of the conveyor belt assembly 1 and the guide assembly 6" refers to the following: one end of the conveyor belt assembly 1 connects to the transfer assembly 5, allowing the cigarette pack 7 to move from the conveyor belt assembly 1 to the transfer assembly 5; the other end of the transfer assembly 5 connects to the guide assembly 6, allowing the cigarette pack 7 to move from the transfer assembly 5 to the guide assembly 6. This indirectly enables the conveyor belt assembly 1 to connect to the guide assembly 6. In other words, the transfer assembly 5, by changing its own posture, acts as a bridge, indirectly enabling the conveyor belt assembly 1 to connect to the guide assembly 6.

[0038] The aforementioned control component is coupled to both the blocking component 3 and the transfer assembly 5, including electrical and signal connections. This control component controls the operating state of the blocking component 3 and the orientation of the transfer assembly 5 based on the congestion status of the lifting belt assembly 2. It is easy to understand that "controlling the operating state of the blocking component 3" refers to controlling the blocking component 3 to perform a blocking action or a resetting action; "controlling the orientation of the transfer assembly 5" refers to controlling the transfer assembly 5 to be in an orientation that allows the conveyor belt assembly 1 to dock with the guide assembly 6, or controlling the transfer assembly 5 to be in an orientation that prevents the conveyor belt assembly 1 from docking with the guide assembly 6 (initial orientation). This control component can be, for example, a programmable logic controller (PLC) or an ARM microcontroller, and those skilled in the art can configure it according to actual usage requirements; further limitations are not provided here.

[0039] Therefore, the present invention provides a cigarette pack anti-congestion mechanism, which includes a blocking component 3 at one end of the conveyor belt assembly 1 that connects with the lifting belt assembly 2, which can block the movement of the cigarette packs 7 on the conveyor belt assembly 1 along the first direction X1; a guide assembly 6 on the side of the lifting belt assembly 2 away from the conveyor belt assembly 1, which guides the cigarette packs 7 on the conveyor belt assembly 1 to the sealing platform 4; a transfer assembly 5 between the lifting belt assembly 2 and the guide assembly 6, which can connect the conveyor belt assembly 1 and the guide assembly 6 by changing its own posture; and a control component coupled to the blocking component 3 and the transfer assembly 5 respectively. The control component can control the operating state of the blocking component 3 and the posture of the transfer assembly 5 according to the congestion of the lifting belt assembly 2. This ensures that when the lifting belt assembly 2 is in normal operation, i.e., without congestion, the control component does not control the operation of the blocking component 3 or the change in the posture of the transfer assembly 5. At this time, the conveyor belt assembly 1 and the lifting belt assembly 2 are normally connected, and the cigarette packs 7 can move normally from the conveyor belt assembly 1 to the lifting belt assembly 2. When the lifting belt assembly 2 becomes congested, the control component controls the blocking component 3 to operate, preventing the cigarette packs 7 on the conveyor belt assembly 1 from continuing to move to the lifting belt assembly 2, thus avoiding further congestion on the lifting belt assembly 2. At the same time, it controls the change in posture of the transfer assembly 5, so that the conveyor belt assembly 1 is connected to the guide assembly 6. The transfer assembly 5 acts as a bridge. After the posture of the transfer assembly 5 changes (i.e., after the conveyor belt assembly 1 is connected to the guide assembly 6), the control component controls the blocking component 3 to reset, so that the cigarette packs 7 on the conveyor belt assembly 1 can resume movement and can move through the transfer assembly 5 to the guide assembly 6, and then be guided by the guide assembly 6 to the sealing platform 4. During the transport of the cigarette packs 7, the cooperation of the blocking component 3, the transfer assembly 5, and the guiding assembly 6 enables the transport path of the cigarette packs 7 to bypass the lifting belt assembly 2 when congestion occurs, thus avoiding congestion at the intersection of the lifting belt assembly 2 and the conveyor belt assembly 1. At the same time, it can alleviate the congestion of the lifting belt assembly 2. During the entire transport of the cigarette packs 7, no downtime maintenance is required, which improves the transport efficiency of the cigarette packs 7 and ensures the continuity of production and capacity.

[0040] In some embodiments, combined with Figure 4 , Figure 5 As shown, the aforementioned transfer assembly 5 includes a support 511, a bearing 51, and a drive assembly 52.

[0041] The aforementioned support member 511 is disposed between the lifting belt assembly 2 and the guide assembly 6 along a second direction X2, where X2 is a vertical direction. The support member 511 may be, for example, a long strip-shaped plate or a cylindrical structure. In the second direction X2, the support member 511 at least partially protrudes from the upper side of the lifting belt assembly, meaning that the support member 511 is higher than the upper surface of the lifting belt assembly 2.

[0042] The aforementioned support member 51 is rotatably connected to the aforementioned support member 511. The support member 51, for example, has a plate-like structure. The rotatable connection between the support member 51 and the support member 511 is achieved, for example, by providing rotating through holes on both the support member 511 and the support member 51, and simultaneously inserting a rotating shaft through both rotating through holes. This achieves a rotatable connection between the support member 51 and the rotating member. It is easily understood that, to improve the support strength of the support member 511 on the support member 51, two support members 511 can be provided, with the two support members 511 respectively located on opposite sides of the support member 51. In this embodiment, the two support members 511 are spaced apart along a third direction X3 on both sides of the support member 51 and are rotatably connected to the support member 51.

[0043] The aforementioned drive assembly 52 is drively connected to the support member 51. The drive assembly 52 is at least partially movable along the second direction X2 to drive the support member 51 into an inclined state or a horizontal state.

[0044] For example, such as Figure 5 As shown, the drive assembly 52 includes: a connector 521, a first connecting shaft 522, a second connecting shaft 523, and a first drive component 525.

[0045] The connector 521 is disposed on the side of the support 511 opposite to the supporting member 51. In other words, the connector 521 and the supporting member 51 are respectively disposed on opposite sides of the support 511. The connector 521 is, for example, a long strip plate structure.

[0046] The first connecting shaft 522 passes through one end of the connector 521 and is rotatably connected to both the connector 521 and the support 511. The second connecting shaft 523 passes through the other end of the connector 521 and is rotatably connected to both the connector 521 and the support 51. The rotatable connection between the second connecting shaft 523 and the support 51 is achieved, for example, by providing a circular groove or a blind hole on the side of the support 51. The end of the second connecting shaft 523 passing through the connector 521 can be inserted into this circular groove or blind hole, thus achieving a rotatable connection between the second connecting shaft 523 and the support 51.

[0047] The first driving member 525 is disposed along the second direction X2, and the first driving member 525 is, for example, a cylinder or an electric actuator. The first driving member 525 is mounted on other fixed objects (e.g., the ground or the mounting bracket of the lifting belt assembly 2) via a mounting base, and the first driving member 525 is rotatably connected to the mounting base. The first driving member 525 is connected to the end of the second connecting shaft 523 away from the support member 51. A transmission pin 524 is also provided between the ends of the first driving member 525 and the second connecting shaft 523, for example. One end of the transmission pin 524 is detachably connected to the second connecting shaft 523, and the other end is detachably connected to the output end of the first driving member 525. The first driving member 525 is coupled to the control component, and the first driving member 525 can drive the second connecting shaft 523 to move along the second direction X2, so that the support member 51 is in an inclined state or a horizontal state. Specifically, taking the initial tilted state of the support member 51 as an example, the output end of the first driving member 525 pushes the second connecting shaft 523 upward in the vertical direction (second direction X2). The second connecting shaft 523 moves upward as a whole. Since the second connecting shaft 523 is connected to the support member 51, the support member 51 also tends to move upward. At the same time, since the support member 51 is connected to the support member 511, the support member 511 can restrict the overall vertical movement of the support member 51. At this time, under the pushing action of the output end of the first driving member 525, the connection part between the support member 51 and the second connecting shaft 523 will move upward in the vertical direction, while the connection part between the support member 51 and the support member 511 will not move upward in the vertical direction. That is, the support member 51 can rotate around the connection part between itself and the support member 511 as the rotation center. Thus, under the driving action of the first driving member 525, the support member 51 can rotate from the initial tilted state to a horizontal state. When the output end of the first driving member 525 pulls the second connecting shaft 523 downward in the vertical direction (second direction X2), the second connecting shaft 523 moves downward as a whole. Since the second connecting shaft 523 is connected to the support member 51, the support member 51 also tends to move downward. At the same time, since the support member 51 is connected to the support member 511, the support member 511 can restrict the overall vertical movement of the support member 51. At this time, under the pulling action of the output end of the first driving member 525, the connection part between the support member 51 and the second connecting shaft 523 will move downward in the vertical direction, while the connection part between the support member 51 and the support member 511 will not move downward in the vertical direction. That is, the support member 51 can rotate around the connection part between itself and the support member 511 as the rotation center. Thus, under the driving action of the first driving member 525, the support member 51 can rotate from a horizontal state to an inclined state.

[0048] With the above configuration, the attitude change of the transfer assembly 5 can be achieved by the cooperation of the support 511, the bearing 51 and the drive assembly 52. ​​The structure is simple, easy to process and manufacture, and easy to install and maintain.

[0049] In some embodiments, such as Figure 3 As shown, the aforementioned blocking assembly 3 includes: a blocking member 31 and a second driving member 32 connected to each other. The second driving member 32 is, for example, a cylinder or an electric push rod, and is mounted on the mounting bracket of the conveyor belt assembly 1. The blocking member 31 is, for example, an L-shaped baffle or a stop block. The second driving member 32 is coupled to the aforementioned control assembly and can drive the blocking member 31 to move along a third direction X3, so that the blocking member 31 can block the smoke strips 7 on the conveyor belt assembly 1 from moving along a first direction X1, where the third direction X3 is the extension direction of the lifting belt assembly 2. With this configuration, the smoke strips 7 on the conveyor belt assembly 1 can be blocked, resulting in a simple structure and convenient use. It is easy to understand that, in order to improve the blocking effect on the smoke strips 7 on the conveyor belt assembly 1, the number of blocking assemblies 3 can be set to two, with the two blocking assemblies 3 respectively located on opposite sides of the conveyor belt assembly 1. The two blocking assemblies 3 can simultaneously block the smoke strips 7 on the conveyor belt assembly 1, thus improving the blocking effect.

[0050] In some embodiments, combined with Figure 6 , Figure 7As shown, the aforementioned guide assembly 6 includes a guide housing and a pusher assembly 64. The guide housing and pusher assembly 64 are mounted on the mounting bracket of the aforementioned lifting belt assembly 2, for example, via a connecting frame 61. The guide housing includes an arc-shaped portion and an outlet portion. The shape or size of the arc-shaped portion is, for example, a quarter circle. The opening at the upper end of the arc-shaped portion (cigarette inlet 62) is parallel to the first direction X1, that is, parallel to the direction of the conveyor belt assembly 1, allowing the cigarettes 7 on the conveyor belt assembly 1 to smoothly enter the arc-shaped portion through the opening at the upper end. The opening at the lower end of the arc-shaped portion is parallel to the second direction X2, which is a vertical direction. The outlet portion is connected to the lower end of the arc-shaped portion, and the opening of the outlet portion (cigarette outlet 63) is positioned directly opposite the sealing platform 4. This design prevents the arc-shaped section from combining with the outlet section to form an arc-shaped guide channel. The cigarette packs 7 on the conveyor belt assembly 1 can enter the arc-shaped section through the opening at the top, be guided by the arc-shaped section, enter the outlet section, and finally be discharged from the outlet section to the sealing platform 4. During this process, the cigarette packs 7 can naturally slide along the arc-shaped surface within the arc-shaped section to the sealing platform 4, avoiding collisions, tipping, or surface wear that might occur from direct drops or rigid pushing. Simultaneously, during the guidance process of the arc-shaped section, the cigarette packs 7 will rotate 90° due to the guiding effect of the arc-shaped structure. The narrow edge contacting the platform surface makes it easier to stack multiple cigarette packs side-by-side, facilitating barcode scanning and packing by operators.

[0051] The aforementioned pushing component 64 is disposed at the outlet of the guide assembly 6 and is capable of pushing the cigarette pack 7 discharged from the outlet to the sealing table 4 along the first direction X1. For example, as... Figure 6 As shown, the pushing assembly 64 includes a third driving member 641, a pusher plate 642, and a fixing plate 643. The third driving member 641 is, for example, a cylinder. The fixing plate 643 is fixedly connected to the connecting frame 61 to fix the third driving member 641. The third driving member 641 is located between the lifting belt assembly 2 and the guide housing and is aligned with the outlet of the guide housing. The pusher plate 642 is fixedly connected to the output end of the third driving member 641. The third driving member 641 can drive the pusher plate 642 to move along the first direction X1 to push the cigarette packs 7 discharged from the outlet to the sealing platform 4 away from the sealing platform 4. With this arrangement, the cigarette packs 7 below the guide assembly 6 can be pushed away in a timely manner, avoiding the accumulation of cigarette packs 7 below the guide assembly 6.

[0052] On the other hand, the present invention provides a control method for a cigarette pack anti-congestion mechanism, applicable to the cigarette pack anti-congestion mechanism described in any of the embodiments above. This cigarette pack anti-congestion mechanism control method includes:

[0053] S100, determine the conveying state of the lifting belt assembly 2; when the conveying state of the lifting belt assembly 2 is congested, the blocking component 3 operates to block the movement of the cigarette pack 7 on the conveyor belt assembly 1, and at the same time changes the posture of the transfer assembly 5 to a horizontal state so that the conveyor belt assembly 1 docks with the guide assembly 6; then, that is, when the posture of the transfer assembly 5 changes to a horizontal state, the blocking component 3 resets and stops blocking the movement of the cigarette pack 7 on the conveyor belt assembly 1.

[0054] S200, determine the conveying state of the lifting belt assembly 2; when the conveying state of the lifting belt assembly 2 is non-congested, the blocking component 3 operates to block the movement of the cigarette pack 7 on the conveyor belt assembly 1, and at the same time changes the posture of the transfer assembly 5 to an inclined state so that the conveyor belt assembly 1 and the lifting belt assembly 2 are connected; then, that is, when the posture of the transfer assembly 5 changes to an inclined state, the blocking component 3 resets and stops blocking the movement of the cigarette pack 7 on the conveyor belt assembly 1.

[0055] The control method for the anti-congestion mechanism of the cigarette pack possesses all the technical features of the anti-congestion mechanism described in any of the embodiments above, and its beneficial effects are the same as those described above, so they will not be repeated here. Furthermore, using the above control method to control the anti-congestion mechanism of the cigarette pack can standardize and streamline the conveying process of the cigarette pack 7 and the handling method when the cigarette pack 7 encounters congestion during conveying. This avoids redundant or erroneous operations by staff when congestion occurs during the conveying of the cigarette pack 7, improves the efficiency of staff in using the anti-congestion mechanism, speeds up the handling of congestion in the cigarette pack 7, and ensures production continuity and capacity.

[0056] In some embodiments, step S100 in the above-mentioned cigarette pack anti-congestion mechanism control method includes:

[0057] S101, define the normal passage time of the cigarette pack 7 on the lifting belt assembly 2 as T0, and obtain the actual passage time T1 of the cigarette pack 7 on the lifting belt assembly 2.

[0058] Specifically, a photoelectric sensor (or laser position sensor, mechanical micro-motion sensor, etc.) is installed on the aforementioned lifting belt assembly 2. T0 is the theoretical time for a single pack of cigarettes 7 to pass through the photoelectric sensor detection area when the lifting belt assembly 2 is uncongested. For example, if the length of the photoelectric sensor detection area is L and the conveyor belt speed in the lifting belt assembly 2 is V, then T0 = L / V (calibrated based on the actual size of the cigarette pack 7 and the conveyor speed). T0 is usually obtained using a calibration method. When the equipment is running unloaded or stably, the photoelectric sensor records the signal time difference between the cigarette pack 7 entering and leaving the detection area, and the average value is taken after multiple measurements as T0.

[0059] T1 is the actual measurement time for a single pack of cigarettes 7 to pass through the same photoelectric sensor detection area under actual operating conditions. For example, when the passage time of the cigarette pack 7 is prolonged due to congestion or tilting, T1 will be significantly greater than T0. T1 can be obtained through real-time detection by installing through-beam photoelectric switches at the entrance and exit of the sensor detection area, recording the start and end timestamps of the cigarette pack 7 blocking the optical axis, and calculating the time difference as T1.

[0060] S102, the difference between T0 and T1 is △T. Based on the relationship between △T and the preset congestion threshold △T1, the conveying state of the lifting belt assembly 2 is determined. When △T > △T1, the conveying state of the lifting belt assembly 2 is a congested state.

[0061] The congestion threshold ΔT1 is a preset value, typically obtained through experimental calibration. Specifically, firstly, an unloaded test is performed on the conveyor mechanism (lifting belt assembly 2). With no cigarette packs 7, the signal stabilization time in the sensor detection area is recorded to eliminate the influence of mechanical vibration or environmental interference. Then, a load test is performed on the conveyor mechanism. Under normal operating conditions (stable conveying speed, no tilting of cigarette packs 7), more than 1000 T1 data points are continuously collected, and the average value is calculated as the baseline T0. Congestion is artificially created, and the peak value of T1 minus T0 is recorded. The upper limit of the 99% confidence interval is taken as ΔT1.

[0062] S103, when the conveying state of the lifting belt assembly 2 is congested, the blocking component 3 operates, and at the same time, the attitude of the transfer assembly 5 is changed to a horizontal state so that the conveying belt assembly 1 is connected to the guide assembly 6; when the attitude of the transfer assembly 5 is changed to a horizontal state, the blocking component 3 is reset.

[0063] In some embodiments, step S200 of the above-described cigarette pack anti-congestion mechanism control method includes:

[0064] S201, based on the relationship between △T and the preset congestion threshold △T1, determine the conveying state of the lifting belt assembly 2; when △T < △T1, the conveying state of the lifting belt assembly 2 is a non-congested state.

[0065] S202, when the conveying state of the lifting belt assembly 2 is non-congested, the blocking component 3 operates, and at the same time changes the posture of the transfer assembly 5 to an inclined state so that the conveying belt assembly 1 and the lifting belt assembly 2 are connected; when the posture of the transfer assembly 5 changes to an inclined state, the blocking component 3 is reset.

[0066] In some embodiments, the calculation method for △T1 in steps S101 and S202 is as follows: First, obtain the actual passing time T1 of the cigarette pack 7 on the lifting belt assembly 2, and continuously record multiple sets; then calculate the average value of the multiple passing times T1 to obtain the average value. Finally, calculate the average value. The difference between T0 and T0 is ΔT.

[0067] Specifically, the single-pass time of cigarette pack 7 may deviate due to sensor malfunctions or momentary vibrations of cigarette pack 7. Averaging multiple data sets can reduce the impact of random errors. Calculating the mean using a large sample size (more than 10 times) makes the result closer to the actual delivery status, avoiding misjudgments caused by occasional events. Furthermore, by continuously recording the T1 sequence, the congestion development trend can be identified, rather than relying solely on a single measurement. The aforementioned T0 can be obtained using calibration methods or as a theoretical normal delivery time set based on equipment parameters or historical data.

[0068] In addition, the congestion on the output belt assembly can be detected. By combining the congestion status of the output belt assembly and the congestion status of the lifting belt assembly 2, the operating mode of the cigarette anti-congestion mechanism can be comprehensively determined. For example, if the output belt assembly is detected to be congested, but the lifting belt assembly 2 is operating normally, the cigarette anti-congestion mechanism can be left unactivated, allowing the cigarettes 7 on the conveyor belt assembly 1 to move naturally to the lifting belt assembly 2. If the output belt assembly is detected to be operating normally, but the lifting belt assembly 2 is congested, the cigarette anti-congestion mechanism can be activated, causing the cigarettes 7 on the conveyor belt assembly 1 to move through the transfer assembly 5 to the guide assembly 6, thus preventing the congestion on the lifting belt assembly 2 from worsening.

[0069] For example, the step of detecting congestion on the output belt assembly is S500, which includes:

[0070] S501, obtain the actual transit time T2 of a single pack of cigarettes 7 on the conveyor belt assembly 1 and continuously record multiple sets.

[0071] S502, calculate the mean of multiple transit times T2, and obtain the average value. .

[0072] S503, Calculate the average value The difference between T0 and T0.

[0073] S504, compare the difference calculated in step S503 with the time threshold △T3; if the difference is less than △T3, it indicates that the conveyor belt assembly 1 is in normal operation; if the difference is greater than △T3, it indicates that the conveyor belt assembly 1 is in a congested state. In this step, △T3 uses a preset fixed value (e.g., 0.005 seconds) instead of dynamic calculation, reducing the amount of real-time calculation. Directly comparing the difference with the fixed △T3 eliminates the need for multi-sensor cross-verification.

[0074] It is easy to understand that the cigarette pack 7 may get stuck during its movement on the transfer assembly 5. In some embodiments, after step S300, the cigarette pack anti-congestion mechanism control method further includes:

[0075] S400, obtain the status information of the cigarette pack 7 on the transfer assembly 5; adjust the posture of the transfer assembly 5 to a horizontal or vertical state according to the status information of the cigarette pack 7.

[0076] For example, step S400 above includes:

[0077] S401, Obtain the status information of the cigarette pack 7 on the transfer assembly 5.

[0078] Specifically, the status information of the cigarette pack 7 can be acquired by setting an industrial camera on the transfer assembly 5. The industrial camera is installed at a top-down angle, with the optical axis of the lens perpendicular to the plane of the support 51 in the transfer assembly 5, covering the entire area of ​​the support 51. The industrial camera acquires one frame every 0.1 seconds, and continuously captures 5 frames for status analysis.

[0079] S402, define the side of the cigarette pack 7 with length × height as side A, and the side with length × width as side B.

[0080] Side A is the length × height of cigarette pack 7, and side B is the length × width of cigarette pack 7. It can be defined simply by measuring the length, width, and height of cigarette pack 7, without complicated algorithms, making it simple and intuitive.

[0081] S403, when the state of cigarette pack 7 is stuck, determine the stuck surface of cigarette pack 7.

[0082] Specifically, when the transfer assembly 5 flips back from the horizontal state to the initial state (tilted state), under ideal conditions, the transfer assembly 5 forms an inclined surface during the flipping process, causing the cigarette packs 7 remaining on the transfer assembly 5 to slide along the inclined surface. When the transfer assembly 5 has an ideal flipping speed and angle, the 2 to 3 packs of cigarette packs 7 remaining on the transfer assembly 5 can slide into the guide assembly 6 during the flipping process.

[0083] However, in reality, the 2 to 3 packs of cigarettes 7 remaining on the transfer assembly 5 all need to overcome friction to slide. The last pack of cigarettes 7 may get stuck on the transfer assembly 5 when it flips back to the initial angle because the sliding path is too long. The cigarettes 7 cannot enter the guide assembly 6 in time. When the A side of the cigarettes 7 faces the guide assembly 6, the A side gets stuck.

[0084] In addition, the cigarette pack 7 may roll during the flipping process of the transfer assembly 5, and roll from the original B side contacting the transfer assembly 5 to the A side contacting the tray. At this time, the rolled cigarette pack 7 slides to the edge of the transfer assembly 5 in a new posture and abuts against the edge of the guide assembly 6, forming a B side jam.

[0085] S404, when the cigarette pack 7 located on the transfer assembly 5 forms a jam on surface A, the transfer assembly 5 changes its own posture to a horizontal state. After the cigarette pack 7 is reset and stabilized on the transfer assembly 5, the transfer assembly 5 changes its own posture to an inclined state, so that the cigarette pack 7 enters the guide assembly 6 under the flipping action of the transfer assembly 5.

[0086] That is, when the cigarette pack 7 gets stuck on side A, the transfer assembly 5 is flipped to a horizontal state and reset again, so that the transfer assembly 5 can generate the force for the remaining cigarette pack 7 to continue sliding during the flipping process, thereby transferring the cigarette pack 7 to the guide assembly 6.

[0087] S405, when the cigarette pack 7 located on the transfer assembly 5 forms a jam on side B, the transfer assembly 5 changes its own posture to a vertical state, so that the cigarette pack 7 falls onto the sealing platform 4 or the ground under the flipping action of the transfer assembly 5.

[0088] When the cigarette pack 7 is stuck on side B, if the control method for side A is continued, that is, the transfer assembly 5 is first flipped to a horizontal state and then reset to an inclined state, the cigarette pack 7 will be squeezed. In order to prevent it from being squeezed, the transfer assembly 5 needs to be flipped to a vertical state, so that the cigarette pack 7 can be directly leaked to the sealing platform 4 or the ground.

[0089] The above settings can prevent the cigarette pack 7 from getting stuck on the transfer assembly 5, improve the continuity of cigarette pack 7 conveying, and prevent the cigarette pack 7 from being squeezed.

[0090] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
