Description

Technical Field

[0001] This application relates to the field of cigarette packaging equipment technology, and in particular to a thrust-stopping device, a paper storage system, and a packaging machine. Background Technology

[0002] The soft-pack and hard-pack packaging unit is a cigarette packaging equipment consisting of a soft-pack packaging machine, a small-pack transparent paper packaging machine, and a carton packaging machine. The soft-pack packaging machine has a rated speed of 600 packs / minute. Its main function is to assemble the cigarettes, wrap them with inner lining paper, wrap them with label paper, and finally form a soft-pack cigarette pack, which is then conveyed to the next production stage.

[0003] The label paper is lifted by an automatic feeding device onto the longitudinal channel of the label paper warehouse. The feeding trolley then transports the stacks of label paper through the longitudinal channel to the label paper warehouse. After the stacks are delivered to the warehouse, the feeding trolley returns to the previous working position to wait for the next stack to arrive, at which point the stacks fall into the warehouse.

[0004] During the retraction of the feeding trolley, the label paper stack is unrestrained. As the trolley retracts, the paper stack tilts slightly forward, and the bottom part of the label paper is easily dragged back onto the channel or onto the side wall of the paper warehouse by the feeding trolley. This leads to poor label paper addition and ultimately causes a failure to pick up the label paper and a shutdown. Utility Model Content

[0005] Therefore, it is necessary to provide a thrust-stopping device, a paper storage system, and a packaging machine to address the problem that during the trolley's retraction process, the paper stack tilts slightly forward, and the bottom part of the label paper is easily dragged backward by the feeding trolley onto the channel or onto the side wall of the paper storage.

[0006] A thrust-stopping device, the thrust-stopping device comprising:

[0007] A fixing component is provided for mounting the thrust device on a paper storage system, the paper storage system having a feeding channel extending along the vertical direction, the thrust device being located at one end of the feeding channel in the feeding direction, and the feeding trolley being able to exit the feeding channel from the other end of the paper storage system along the feeding direction, the feeding direction intersecting the vertical direction;

[0008] A spring element, disposed in the fixing assembly and capable of being located within the feeding channel, allows the paper stack to abut against one side of the paper stack in the feeding direction and the bottom of the paper stack when the feeding trolley inputs the paper stack into the feeding channel; when the feeding trolley exits the feeding channel, the spring element can deform under the gravity of the paper stack and allow the paper stack to fall along the feeding channel.

[0009] In one embodiment, the spring includes a fixed part and an elastic part connected to each other. The fixed part is mounted on a fixing assembly, and the elastic part is capable of bending relative to the fixed part about a bending axis under the action of an external force. The bending axis direction intersects both the vertical direction and the feeding direction.

[0010] In one embodiment, the fixing part further includes a guide part, one end of which is connected to the end of the elastic part away from the fixing part, and when the thrust stop device is installed in the paper cartridge system, the other end of the guide part extends longitudinally along the vertical direction.

[0011] In one embodiment, the fixing part, the elastic part, and the guide part are all integrally formed, and the elastic part is intersecting with the fixing part.

[0012] In one embodiment, when the thrust stop device is installed in the paper cartridge system, the elastic part intersects with both the vertical direction and the feeding direction.

[0013] In one embodiment, the thrust device further includes a mounting bolt, the fixing part has a fixing hole, the fixing component has a mounting hole, the mounting bolt passes through the fixing hole and the mounting hole, and fixes the fixing part to the fixing component.

[0014] In one embodiment, the fixing component includes a fixed bracket and an adjusting bracket. The fixed bracket is used to install the thrust stop device on the paper feed system, and the adjusting bracket is installed on the fixed bracket and its position relative to the fixed bracket in the feeding direction is adjustable.

[0015] In one embodiment, the thrust device further includes an adjusting bolt, the adjusting bracket has a waist-shaped hole extending longitudinally along the feeding direction, the fixed bracket has a fixed threaded hole, and the adjusting bolt passes through the waist-shaped hole and is threadedly connected to the fixed threaded hole.

[0016] A paper storage system includes a feeding channel and a thrust device as described in any of the preceding claims.

[0017] A packaging machine includes a feeding trolley and a paper storage system as described in any of the preceding claims.

[0018] In the aforementioned thrust-stopping device, when the feeding trolley inputs the paper stack into the feeding channel, the spring abuts against one side of the paper stack. During the process of the feeding trolley exiting the feeding channel, the paper stack will have inertia to move towards the elastic element because the feeding trolley is disengaged. However, since the spring abuts against the paper stack, the elastic element will restrict the movement of the paper stack, thereby preventing the paper stack from tilting forward.

[0019] By having the bottom of the paper stack abut against the spring, the weight of the paper stack is applied to the spring as the feeding trolley exits the feeding channel. This spring, the spring exerts a longitudinal constraint on the paper stack, pressing it firmly against the spring. In this way, the bottom label paper is pressed firmly against the spring. As the feeding trolley exits the feeding channel, the bottom label paper is less likely to be pulled by the feeding trolley, preventing it from dragging the label paper backwards and reducing issues such as improper label paper addition and poor label paper absorption leading to machine shutdowns.

[0020] Finally, after the feeding trolley has completely exited the unloading channel, the feeding trolley no longer supports the paper stack. The weight of the paper stack will then act entirely on the elastic element, causing the elastic element to deform. The paper stack will then fall along the unloading channel to complete the paper stack storage. Attached Figure Description

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a packaging machine including a feeding trolley, a paper storage system 100, and a label paper storage device. Label paper stored in the label paper storage device is fed into the paper storage system 100 via the feeding trolley. The paper storage system 100 has a discharge channel 110 extending vertically in the X direction. Label paper in the label paper storage device is stacked on the feeding trolley by gripping or other means to form a paper stack. The feeding trolley then transports the paper stack into the discharge channel 110. Finally, the feeding trolley quickly reverses to exit the discharge channel 110, causing the paper stack on the feeding trolley to detach and fall freely within the discharge channel 110, thus completing the label paper storage.

[0035] Specifically, the feeding device has openings 120 on the top and side walls of the feeding channel 110. The feeding trolley carries the paper stack into the feeding channel 110 through the opening 120 on the top and exits the feeding channel 110 through the opening 120 on the side wall. When the feeding trolley leaves the feeding channel 110, because the size of the opening 120 on the side wall of the feeding channel 110 is smaller than the width of the paper stack, the paper stack can remain in the feeding channel 110. Then, the paper stack undergoes free fall to complete the label paper storage.

[0036] When the feeding trolley leaves the unloading channel 110, although the paper stack is limited by the inner wall of the channel 110 and will not leave with the feeding trolley, friction between the paper stack and the feeding trolley during the exit process causes the paper stack to still move a certain distance with the feeding trolley, resulting in the paper stack tilting forward. Furthermore, the label paper at the bottom of the paper stack is dragged along by the friction with the feeding trolley, causing the feeding trolley to pull on the label paper, leading to poor label paper addition and ultimately causing a label paper poor-absorption malfunction and machine shutdown.

[0037] To address the aforementioned issues, a thrust-stopping device 10 is provided on the paper storage system 100. The thrust-stopping device 10 includes a fixing component 11 and a spring component 12. The fixing component 11 is mounted on the paper storage system 100. When the thrust-stopping device 10 is mounted on the paper storage system 100, the fixing component 11 is located at one end of the feeding channel 110 in the feeding direction Y. The feeding carriage can exit the feeding channel 110 from the other end of the paper storage system 100 along the feeding direction Y. The feeding direction Y intersects with the vertical direction X, meaning the fixing component 11 is located on the opposite side of the opening 120 on the side wall of the feeding channel 110.

[0038] The spring member 12 is provided on the fixing component 11 and can be located in the feeding channel 110. When the feeding carriage inputs the paper stack into the feeding channel 110, the spring member 12 can abut against the paper stack on one side of the feeding direction Y and the bottom of the paper stack. When the feeding carriage exits the feeding channel 110, the spring member 12 can deform under the gravity of the paper stack and allow the paper stack to fall along the feeding channel 110.

[0039] Thus, when the feeding trolley feeds the paper stack into the unloading channel 110, the spring member 12 abuts against one side of the paper stack. During the process of the feeding trolley exiting the unloading channel 110, the paper stack will have inertia to move towards the elastic member because the feeding trolley is disengaged. However, since the spring member 12 abuts against the paper stack, the elastic member will restrict the movement of the paper stack, thereby preventing the paper stack from tilting forward.

[0040] As the bottom of the paper stack abuts against the spring element 12, the weight of the paper stack is applied to the elastic element during the process of the feeding trolley exiting the feeding channel 110. This creates a longitudinal constraint on the paper stack, pressing it firmly against the elastic element. Consequently, the label paper at the bottom of the paper stack is pressed against the elastic element, preventing it from being dragged along by the feeding trolley during exiting the feeding channel 110. This avoids the feeding trolley pulling the label paper backwards, reducing the occurrence of label paper addition errors and machine shutdowns due to poor label paper absorption.

[0041] Finally, after the feeding trolley has completely exited the unloading channel 110, the feeding trolley no longer supports the paper stack. The weight of the paper stack will then act entirely on the elastic element, causing the elastic element to deform. The paper stack will then fall along the unloading channel 110 to complete the paper stack storage.

[0042] In some embodiments of this application, the spring member 12 includes a fixed part 13 and an elastic part 14 connected to each other. The fixed part 13 is mounted on the fixed assembly 11, and the elastic part 14 can bend relative to the fixed part 13 around a bending axis under the action of an external force. The bending axis direction intersects both the vertical direction X and the feeding direction Y. When the thrust device 10 is installed in the paper storage system 100, the elastic part 14 can extend into the fixed channel and abut against the bottom of the paper stack, thereby fixing the trademark paper at the bottom of the paper stack through the elastic part 14, preventing the bottom trademark paper from being dragged by the feeding trolley when it leaves the unloading channel 110.

[0043] After the feeding trolley leaves the unloading channel 110, the elastic part 14 bends relative to the fixed part 13 around the bending axis under the gravity of the paper stack. This allows the elastic part 14 to avoid the paper stack, enabling the paper stack to fall within the unloading channel 110 and complete the paper stack's storage. Furthermore, after the paper stack has completely passed the elastic part 14, the elastic part 14 will return to its original shape as it is no longer subjected to external force from the paper stack. This allows the elastic part 14 to continue contacting the bottom of the newly input paper stack when the next batch of paper stacks is transported to the unloading channel 110.

[0044] It should be noted that when the paper stack is transported into the unloading channel 110 by the feeding car, the side wall of the paper stack in the feeding direction Y can only contact the elastic part 14, thereby limiting the tilt of the paper stack through the elastic part 14, or it can contact both the elastic part 14 and the fixing part 13 at the same time, thereby limiting the tilt of the paper stack through the fixing part 13 and the elastic part 14 together. The specific choice can be made according to the thickness of the paper stack, and is not limited here.

[0045] In some embodiments, the fixing part 13 further includes a guide part 15. One end of the guide part 15 is connected to the end of the elastic part 14 away from the fixing part 13. When the thrust device 10 is installed in the paper storage system 100, the other end of the guide part 15 extends longitudinally in the vertical direction X. After the feeding carriage leaves the unloading channel 110, the paper stack will cause the elastic part 14 to bend and fall. During the falling process, the side of the paper stack will pass through the guide part 15. Since the guide part 15 extends in the vertical direction X, the side of the paper stack will be flattened under the action of the guide part 15. Even if the paper stack is slightly tilted forward, the tilted part will contact the guide part 15 and flatten the paper stack through the guide part 15 to ensure the flatness of the paper stack entering the storage, so as to facilitate the subsequent suction of the label paper in the paper stack.

[0046] In some specific embodiments, the fixing part 13, the elastic part 14 and the guide part 15 are all integrally formed, so that there is no need to provide a connecting part between the fixing part 13, the elastic part 14 and the guide part 15, thereby reducing the number of parts of the thrust device 10 and reducing installation and production costs.

[0047] The elastic part 14 and the fixed part 13 are intersecting, that is, the extension direction of the elastic part 14 intersects the extension direction of the fixed part 13, so that there is a corner between the elastic part 14 and the fixed part 13. When the elastic part 14 is subjected to an external force, such as the weight of the paper stack, the elastic part 14 will deform at the corner, thereby causing the elastic part 14 to bend relative to the fixed part 13, and the bending axis is located at the connection between the elastic part 14 and the fixed part 13.

[0048] Furthermore, when the thrust stop device 10 is installed in the paper storage system 100, the elastic part 14 intersects both the vertical direction X and the feeding direction Y, meaning the elastic part 14 is in an inclined state. This facilitates the elastic part 14 extending into the bottom of the paper stack, and the bottom side of the paper stack near the thrust stop device 10 will contact the elastic part, thereby pressing the bottom label paper of the paper stack firmly through the elastic part 14. The side of the paper stack will contact the fixing part 13 or the elastic part 14 to prevent forward tilting. When the feeding carriage leaves the unloading channel 110, the inclined elastic part 14 is also more likely to bend relative to the fixing part, so that the paper stack can continue to fall through the spring part 12.

[0049] It should be noted that in some other embodiments, the fixing part 13 may also be arranged perpendicularly to the elastic part 14, that is, the elastic part 14 extends longitudinally along the feeding direction Y, so that the elastic part 14 and the fixing part 13 are L-shaped. In this way, when the feeding carriage feeds the paper stack into the unloading channel 110, the elastic part 14 will extend completely into the bottom of the paper stack, thereby pressing the trademark paper at the bottom of the paper stack.

[0050] Furthermore, in some embodiments, the elastic part 14 can also be disposed on the fixed part 13 by means of a rotating shaft, and a torsion spring is also disposed on the rotating shaft. After the elastic element is bent under the action of external force, if the external force is removed, the torsion spring will drive the elastic element to return to its original state.

[0051] In some specific embodiments, the thrust device 10 further includes a mounting bolt, a fixing hole is provided on the fixing part 13, and a mounting hole 16 is provided on the fixing component 11. The mounting bolt passes through the fixing hole and the mounting hole 16, and fixes the fixing part 13 to the fixing component 11. In other embodiments, the fixing part 13 can also be fixed to the fixing component 11 by welding, riveting, or other methods.

[0052] In some embodiments of this application, the fixing component 11 includes a fixing bracket 17 and an adjusting bracket 18. The fixing bracket 17 is used to mount the thrust stop device 10 onto the paper feed system 100. The adjusting bracket 18 is mounted on the fixing bracket 17, and the position of the adjusting bracket 18 relative to the fixing bracket 17 in the feeding direction Y is adjustable. Thus, by adjusting the position of the adjusting bracket 18 relative to the fixing bracket 17, the position of the spring member 12 relative to the fixing bracket 17 can be adjusted, thereby adjusting the contact force between the spring member 12 and the paper stack, so that the position of the spring member 12 can be adjusted according to the thickness of the paper stack.

[0053] In some embodiments, the thrust device 10 further includes an adjusting bolt. An oblong hole 19 extending along the Y-direction of the feeding direction is provided on the adjusting bracket 18, and a fixed threaded hole 20 is provided on the fixed bracket 17. The adjusting bolt passes through the oblong hole 19 and is threadedly connected to the fixed threaded hole 20. Thus, the oblong hole 19 allows the adjusting bracket 18 to move relative to the adjusting bolt, thereby changing the position of the adjusting bracket relative to the fixed bracket 17, and consequently adjusting the position of the spring member 12.

[0054] Optionally, there are two adjusting bolts, one oblong hole 19, and one fixed threaded hole 20. Each adjusting bolt corresponds to one oblong hole 19 and one fixed threaded hole 20, thereby increasing the installation strength of the adjusting bracket on the fixed bracket 17 through the two adjusting bolts.

[0055] The aforementioned thrust-stopping device 10 has at least the following advantages:

[0056] When the feeding trolley feeds the paper stack into the unloading channel 110, the spring member 12 abuts against one side of the paper stack. During the process of the feeding trolley exiting the unloading channel 110, the paper stack will have inertia to move towards the elastic member because the feeding trolley is disengaged. However, since the spring member 12 abuts against the paper stack, the elastic member will restrict the movement of the paper stack, thereby preventing the paper stack from tilting forward.

[0057] As the bottom of the paper stack abuts against the spring element 12, the weight of the paper stack is applied to the elastic element during the process of the feeding trolley exiting the feeding channel 110. This creates a longitudinal constraint on the paper stack, pressing it firmly against the elastic element. Consequently, the label paper at the bottom of the paper stack is pressed against the elastic element, preventing it from being dragged along by the feeding trolley during exiting the feeding channel 110. This avoids the feeding trolley pulling the label paper backwards, reducing the occurrence of label paper addition errors and machine shutdowns due to poor label paper absorption.

[0058] Finally, after the feeding trolley has completely exited the unloading channel 110, the feeding trolley no longer supports the paper stack. The weight of the paper stack will then act entirely on the elastic element, causing the elastic element to deform. The paper stack will then fall along the unloading channel 110 to complete the paper stack storage.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
