Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging machine technology, and in particular to a cigarette pack lifting device and packaging machine. Background Technology

[0002] In cigarette packaging production, the lifting device is a crucial component of the packaging machine, used for transporting cigarette packs. It includes a lifting channel and a conveyor pusher. The lifting channel controls the positioning and speed of the formed cigarette packs during transport, while the conveyor pusher fixes the position of the cigarette packs on the conveyor belt and propels them along the belt's trajectory to ensure even distribution and prevent accumulation. The conveyor pusher is typically engaged with the conveyor belt. If the cigarette packs become blocked, the pusher can be squeezed, causing it to detach. A detached pusher can even break the conveyor belt, damaging the cigarette packs and disrupting the continuous transport of cigarette packs from upstream, thus affecting the normal operation of the packaging equipment.

[0003] Currently, when operators discover an abnormal position or detachment of the conveyor pusher, they must immediately stop the machine, adjust the conveyor belt's operating position, and reposition the pusher along the entire conveyor belt by reinstalling or replacing it. The equipment is then restarted to observe the distribution of smoke strips in the lifting channel. If misalignment or blockage persists, the adjustment steps must be repeated. On one hand, the existing lifting device is highly dependent on manual labor, requiring operators to constantly monitor the pusher's status, which easily leads to delayed response times and significantly increases the risk of equipment damage due to failure to stop the machine in time. On the other hand, the lifting device lacks the ability to predict and diagnose potential faults, making it difficult to implement preventative measures in advance and greatly limiting the scope for preventative maintenance.

[0004] Therefore, there is an urgent need to propose a cigarette stick lifting device and a packaging machine to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cigarette pack lifting device and packaging machine to reduce reliance on manual labor, reduce the monitoring burden on operators, shorten response time, improve production efficiency, reduce production costs, create sufficient space for preventive maintenance, ensure the stable and efficient operation of packaging equipment, and improve the overall quality and efficiency of cigarette packaging production.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A cigarette stick lifting device includes a conveyor belt, a pusher detection assembly, multiple conveying pushers, and a marker. The multiple conveying pushers are spaced apart on the conveyor belt along the conveying direction. The conveying pushers are configured to drive the cigarette stick to move with the conveyor belt. Each of the conveying pushers is provided with the marker. The pusher detection assembly is used to detect the marker on the conveying pusher.

[0008] Furthermore, the marker is a metal sheet, and the pusher detection assembly includes a metal detection photoelectric switch.

[0009] Furthermore, the cigarette bar lifting device also includes a drive assembly, the output end of which is connected to the conveyor belt for driving the conveyor belt to move along its transport direction, and the push head detection assembly is signal connected to the drive assembly.

[0010] Furthermore, the conveyor belt includes a horizontal section, a transition section, and a vertical section connected sequentially along its transport direction. The cigarette stick lifting device further includes a missing pack detection component and a rejection component. The missing pack detection component is mounted on the vertical section of the conveyor belt and is used to detect missing cigarette sticks. The rejection component is located downstream of the missing pack detection component and is signal-connected to the missing pack detection component, used to drive the missing cigarette sticks to detach from the conveyor belt. The pusher detection component includes a first detection element and a second detection element. Both the first detection element and the second detection element are used to detect the marking element. The first detection element is located upstream of the missing pack detection component along the transport direction of the conveyor belt, and the second detection element is located downstream of the rejection component along the transport direction of the conveyor belt.

[0011] Furthermore, the rejection assembly includes a rejection drive and a pusher plate. The rejection drive is disposed on one side of the conveyor belt and is signal-connected to the missing pack detection assembly. The output end of the rejection drive is drive-connected to the pusher plate to drive the pusher plate to push the missing pack cigarette stick away from the conveyor belt.

[0012] Furthermore, the cigarette pack lifting device also includes a collection component, which includes a collection channel. The collection channel is located on the side of the conveyor belt away from the rejection drive, and the inlet of the collection channel is opposite to the push plate for receiving the missing pack of cigarette packs.

[0013] Furthermore, the collection assembly also includes a cover plate, which is disposed at the entrance of the collection channel and covers the vertical section to prevent the missing cigarette pack from falling off.

[0014] Furthermore, the cigarette stick lifting device also includes a cigarette pressing assembly, which includes a limiting member located upstream of the missing pack detection assembly and disposed on the outside of the vertical section. A limiting space is formed between the limiting member and the vertical section, allowing the cigarette sticks on the conveyor belt to enter the missing pack detection assembly through the limiting space. The first detection element is disposed at the entrance of the limiting space.

[0015] Furthermore, the opening of the limiting space facing upstream of the conveyor belt is flared; and / or,

[0016] The smoke-pressing assembly also includes a roller, which is rotatably connected to the limiting member, and the rotation axis of the roller is perpendicular to the transport direction of the conveyor belt. The surface of the roller can abut against the smoke bar.

[0017] A packaging machine includes a packaging device and a cigarette stick lifting device as described in any of the preceding claims, the packaging device being disposed at the end of the conveyor belt along the conveying direction for receiving cigarette sticks on the conveyor belt and packaging the cigarette sticks.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a cigarette stick lifting device and packaging machine, including a conveyor belt, a pusher detection component, multiple conveying pushers and marking elements. The multiple conveying pushers are spaced apart on the conveyor belt along the transmission direction of the conveyor belt. The conveying pushers are configured to drive the cigarette sticks to move with the conveyor belt. Each conveying pusher is provided with a marking element. The pusher detection component is used to detect the marking elements on the conveying pushers. The spacing between adjacent conveyor pushers is used to accommodate cigarette sticks. The pushers fix the position of the cigarette sticks on the conveyor belt and push them along the belt's trajectory to ensure even distribution and prevent accumulation. Markers are placed on the pushers; when a pusher passes a pusher detection component, the component records the detection signal from each marker. By comparing and amplifying the signal detection interval with the conveyor belt speed, the actual spacing between pushers is determined. If the signal interval exceeds a set time twice consecutively, it indicates that a pusher has detached or a cigarette stick blockage has occurred. In this case, the pusher detection component will issue a stop signal and an alarm signal to prevent cigarette stick damage and excessive pusher detachment, and to alert operators for handling and maintenance. This setup enables automatic monitoring of the pusher's operating status, reducing reliance on manual labor, lessening the operator's monitoring burden, shortening response time, improving production efficiency, reducing production costs, creating ample space for preventative maintenance, ensuring stable and efficient operation of packaging equipment, and improving the overall quality and efficiency of cigarette packaging production.

[0033] 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 present 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, not the entire structure.

[0034] In the description of this utility model, 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 utility model based on the specific circumstances.

[0035] 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.

[0036] In the description of this embodiment, the terms "upper," "lower," "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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] like Figures 1-3 As shown, this embodiment provides a cigarette stick lifting device, including a conveyor belt 1, a pusher detection component 2, multiple conveying pushers 3 and a marker 4. The multiple conveying pushers 3 are spaced apart on the conveyor belt 1 along the transmission direction of the conveyor belt 1. The conveying pushers 3 are configured to drive the cigarette stick 100 to move with the conveyor belt 1. Each conveying pusher 3 is provided with a marker 4. The pusher detection component 2 is used to detect the marker 4 on the conveying pusher 3.

[0038] The interval between adjacent conveyor pushers 3 is used to accommodate cigarette sticks 100. The conveyor pushers 3 are used to fix the position of the cigarette sticks 100 on the conveyor belt 1 and push the cigarette sticks 100 to move along the movement trajectory of the conveyor belt 1 to ensure that the cigarette sticks 100 are evenly distributed and to avoid the accumulation of cigarette sticks 100. By setting markers 4 on the conveyor pushers 3, when the conveyor pushers 3 pass the pusher detection component 2, the pusher detection component 2 can record the detection signal of the markers 4 on each conveyor pusher 3. By comparing and amplifying the signal detection interval time with the running speed of the conveyor belt 1, the actual interval between the conveyor pushers 3 can be determined. When the signal interval time is greater than the set time twice in a row, it can be determined that the conveyor pusher 3 has fallen off or the cigarette sticks 100 have been blocked. At this time, the pusher detection component 2 will issue a stop signal and an alarm signal to avoid damage to the cigarette sticks 100 and prevent a large number of conveyor pushers 3 from falling off, and to remind the operator to handle and maintain the situation. The above settings enable automatic monitoring of the working status of the conveyor pusher 3, reduce the dependence of the lifting device on manual labor, reduce the monitoring burden on operators, shorten response time, improve production efficiency, reduce production costs, create sufficient space for preventive maintenance, ensure the stable and efficient operation of packaging equipment, and improve the overall quality and efficiency of cigarette packaging production.

[0039] In order to reduce the load on the transmission belt, the conveyor pusher 3 is made of polymer material. In order to facilitate the identification of detection signals, the marker 4 is a metal sheet in this embodiment. The pusher detection component 2 includes a metal detection photoelectric switch. The addition of a metal sheet to the conveyor pusher 3 has a simple structure and low cost. The metal detection switch has high sensitivity to the metal sheet. Even if the workpiece speed is fast or the metal sheet size is small, it can provide reliable detection results, providing accurate data support for speed control and quality monitoring in the production process.

[0040] In other embodiments, the push head detection component 2 includes, but is not limited to, a photoelectric sensor or an ultrasonic sensor, and the marker 4 includes, but is not limited to, a light reflector or an ultrasonic reflector, which are not limited here.

[0041] To improve the sensitivity and accuracy of the detection of the conveyor pusher 3, the pusher detection component 2 is set on one side of the conveyor belt 1. Each metal piece is set on the side of the conveyor pusher 3 near the detection end of the pusher detection component 2, and the metal pieces are at the same height as the detection end of the pusher detection component 2, so as to ensure that when the conveyor pusher 3 passes the pusher detection component 2, the metal pieces are directly opposite the detection end of the pusher detection component 2.

[0042] like Figure 1As shown, the cigarette bar lifting device further includes a drive assembly 5. The output end of the drive assembly 5 is connected to the conveyor belt 1 for driving the conveyor belt 1 to move along its transport direction. The pusher detection assembly 2 is connected to the drive assembly 5 for signaling. The running speed of the conveyor belt 1 can be calculated based on the running speed of the output end of the drive assembly 5. By comparing and amplifying the signal detection interval time with the running speed of the conveyor belt 1, the actual interval between the metal sheet conveying pushers 3 can be determined.

[0043] The drive component 5 includes, but is not limited to, drive motors, pneumatic motors, or hydraulic motors, etc., which are not limited here.

[0044] In some optional embodiments, the cigarette bar lifting device also includes a control panel 10, which is communicatively connected to the drive assembly 5 and the pusher detection assembly 2. When the pusher detection assembly 2 issues a stop signal and an alarm signal, the control panel 10 can control the drive assembly 5 to stop output and display fault information to facilitate maintenance by staff.

[0045] like Figure 1 As shown, the conveyor belt 1 includes a horizontal section 11, a transition section 12, and a vertical section 13 connected sequentially along its transport direction. The cigarette stick lifting device also includes a missing pack detection component 6 and a rejection component 7. The missing pack detection component 6 is mounted on the vertical section 13 of the conveyor belt 1 and is used to detect missing cigarette sticks 100. The rejection component 7 is located downstream of the missing pack detection component 6 along the transport direction of the conveyor belt 1 and is signal-connected to the missing pack detection component 6 to drive the missing cigarette sticks 100 away from the conveyor belt 1. The push head detection component 2 includes a first detection element 21 and a second detection element 22. Both the first detection element 21 and the second detection element 22 are used to detect the marking element 4. The first detection element 21 is located upstream of the missing pack detection component 6 along the transport direction of the conveyor belt 1, and the second detection element 22 is located downstream of the rejection component 7 along the transport direction of the conveyor belt 1. In actual production, when the cigarette sticks 100 enter the front end of the missing pack detection component 6, they are easily blocked by the missing pack detection component 6 and become clogged, which in turn causes the conveyor pusher 3 to fall off. The first detection element 21 is set upstream of the missing pack detection component 6 along the transport direction of the conveyor belt 1, which can detect the blockage of the cigarette sticks 100 or the fall off of the conveyor pusher 3 in time. Similarly, when the rejection component 7 rejects the missing pack cigarette sticks 100, it may accidentally touch the conveyor pusher 3, causing the pusher to fall off. The second detection element 22 is set downstream of the rejection component 7 along the transport direction of the conveyor belt 1, which can detect the fall off of the pusher in time and avoid affecting the normal production of the packaging equipment.

[0046] Specifically, the rejection assembly 7 includes a rejection drive 71 and a push plate 72. The rejection drive 71 is disposed on one side of the conveyor belt 1 and is signal-connected to the missing pack detection assembly 6. The output end of the rejection drive 71 is drive-connected to the push plate 72 to drive the push plate 72 to push the missing pack cigarette stick 100 away from the conveyor belt 1. When the missing pack detection assembly 6 detects the missing pack cigarette stick 100, it can send a signal to the rejection drive 71. After receiving the signal, the rejection drive 71 drives the push plate 72 to push the missing pack cigarette stick 100 away from the conveyor belt 1, thereby timely rejecting the missing pack cigarette stick 100 and preventing a large number of cigarette sticks 100 from clogging the conveyor belt 1. Optionally, the rejection drive frame may include, but is not limited to, a cylinder or a hydraulic cylinder, etc., which are not limited here.

[0047] Among them, the missing package detection component 6 includes, but is not limited to, a radiation detector or an ultrasonic detector, which is not limited here.

[0048] Furthermore, the cigarette bar lifting device also includes a collection component 8, which includes a collection channel 81. The collection channel 81 is located on the side of the conveyor belt 1 away from the rejection drive 71, and the inlet of the collection channel 81 is opposite to the push plate 72 for receiving the missing cigarette bars 100 so as to recycle the missing cigarette bars 100.

[0049] In this embodiment, the collection component 8 also includes a cover plate 82, which is disposed at the entrance of the collection channel 81 and covers the vertical section 13 to prevent the missing cigarette sticks 100 from falling. The cover plate 82 limits the cigarette sticks 100 and prevents the cigarette sticks 100 in the vertical section 13 from tipping over and falling under the action of gravity, thereby avoiding the falling cigarette sticks 100 from causing blockage of the conveyor belt 1 or detachment of the conveyor pusher 3.

[0050] like Figure 1 and Figure 2 As shown, the cigarette bar lifting device further includes a cigarette pressing component 9, which includes a limiting member 91. The limiting member 91 is located upstream of the missing pack detection component 6 along the conveyor belt 1 transport direction and is disposed on the outside of the vertical section 13. A limiting space is formed between the limiting member 91 and the vertical section 13. The cigarette bar 100 on the conveyor belt 1 can enter the missing pack detection component 6 through the limiting space. The first detection component 21 is disposed at the entrance of the limiting space. When the cigarette stick 100 enters the vertical section 13 from the transition section 12, the angle changes significantly, making it prone to tipping over under gravity. The limiting component 91 can limit and guide the cigarette stick 100, ensuring its smooth lifting and preventing it from falling and causing blockage or detachment of the conveyor pusher 3. In addition, due to the change in the angle of the cigarette stick 100 and the obstruction of the limiting component 91, the front end of the limiting component 91 is a high-risk location for cigarette stick blockage. By placing the first detection component 21 at the entrance of the limiting space, it is possible to detect cigarette stick blockage or detachment of the conveyor pusher 3 in a timely manner.

[0051] Furthermore, the opening of the limiting space facing upstream of the conveyor belt 1 is flared to facilitate the smooth entry of the smoke stick 100 into the limiting space and prevent the workpiece from being stuck by the limiting member 91. Specifically, the portion of the limiting member 91 facing upstream of the conveyor belt 1 is bent away from the conveyor belt 1 to form the flared opening of the limiting space.

[0052] In addition, the cigarette pressing assembly 9 also includes a roller 92, which is rotatably connected to the limiting member 91. The rotation axis of the roller 92 is perpendicular to the transport direction of the conveyor belt 1. The surface of the roller 92 can abut against the cigarette stick 100. When the cigarette stick 100 enters the limiting space, the surface of the roller 92 abuts against the cigarette stick 100. During the process of the cigarette stick 100 being transported by the conveyor belt 1, the roller 92 plays a limiting and supporting role for the cigarette stick 100, preventing the cigarette stick 100 from shaking, deviating or tipping on the conveyor belt 1, and ensuring that the cigarette stick 100 moves smoothly along the predetermined transport direction. In addition, when the cigarette stick 100 moves on the conveyor belt 1, the roller 92 rotates accordingly. The rolling friction contact reduces the wear between the cigarette stick 100 and the cigarette pressing assembly 9, which helps to protect the cigarette stick 100 and avoids squeezing or wear on the appearance and interior of the cigarette stick 100.

[0053] Furthermore, this embodiment also provides a packaging machine, including a packaging device and a cigarette stick lifting device of any of the above embodiments. The packaging device is located at the end of the conveyor belt 1 along the conveying direction and is used to receive cigarette sticks 100 on the conveyor belt 1 and package the cigarette sticks 100. By adopting the above-mentioned cigarette stick lifting device, the working status of the conveyor pusher 3 can be automatically monitored, reducing the dependence on manual labor, reducing the monitoring burden of operators, shortening the response time, improving production efficiency, reducing production costs, creating sufficient space for preventive maintenance, ensuring the stable and efficient operation of the packaging equipment, and improving the overall quality and efficiency of cigarette packaging production.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. 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 this utility model should be included within the protection scope of the claims of this utility model.
