Description

Technical Field

[0001] This application relates to the field of cigarette packaging equipment technology, and in particular to a guide plate device, a transport system and a packaging machine. Background Technology

[0002] The GDX6S soft pack / hard carton packaging unit is a cigarette soft pack / hard carton packaging equipment designed and manufactured by the Italian company GD. This unit consists of the X6S soft pack packaging machine, the C800 small box transparent paper packaging machine, and the BV carton packaging machine. The X6S soft pack packaging machine has a rated speed of 600 packs / minute. Its main function is to assemble the cigarettes, wrap them with inner liner paper, wrap them with label paper, and finally form a soft pack of cigarettes, which is then conveyed to the next production stage.

[0003] After the label paper is coated and wrapped, it is transferred to the cigarette pack lifting beam and then to the next process. Currently, the inlet guide plate uses a magnetic design with some overload protection. When a blockage occurs in the cigarette pack conveying at the inlet guide plate, the guide plate will overcome the magnetic force and open, triggering an alarm on the proximity switch on the guide plate and stopping the equipment. However, due to the relatively weak magnetic force, the inlet guide plate often cannot completely fit the cigarette pack, easily resulting in gaps that prevent the cigarette pack from contacting the heating plate. Utility Model Content

[0004] Therefore, it is necessary to provide a guide plate device, a transport system, and a packaging machine to address the problem that the inlet guide plate often cannot fully fit the cigarette pack.

[0005] A guide plate device, comprising:

[0006] Fixed bracket;

[0007] An inlet guide plate includes two opposite ends along a first direction, one end of which is rotatably mounted on the fixed bracket;

[0008] A spring plate is located on one side of the inlet guide plate in the second direction and includes two opposite ends along the first direction, one end of which is mounted on the fixed bracket, and the other end is connected to the middle of the inlet guide plate or the end away from the fixed bracket. The second direction, the first direction, and the direction of the rotation axis intersect each other.

[0009] In one embodiment, the guide plate device further includes a connector, the connector having two opposite ends along the second direction, and the two ends of the connector respectively abutting or connecting with the end of the spring plate away from the fixed bracket and the inlet guide plate, the position of the connector abutting or connecting with the inlet guide plate being located in the middle of the inlet guide plate or away from the fixed bracket.

[0010] The second direction, the first direction, and the direction of the rotation axis intersect each other but are not coplanar.

[0011] In one embodiment, the connector is configured to elastically deform along the second direction.

[0012] In one embodiment, the spring plate has an adjustment hole, the inlet guide plate has a fixing threaded hole, and the guide plate device further includes an adjustment bolt. The adjustment bolt includes a head and a screw. The head is located at one end of the screw. The screw passes through the adjustment hole and is threadedly connected to the fixing threaded hole. The size of the head is larger than that of the adjustment hole.

[0013] In one embodiment, the connector is a spring, which is sleeved on the screw.

[0014] In one embodiment, the guide plate device further includes a connecting post extending longitudinally along a second direction, and the connecting post has a connecting hole.

[0015] The guide plate device also includes a clamping bolt, the spring plate has a mounting hole, the fixed bracket has a connecting threaded hole, the clamping bolt passes through the mounting hole and the connecting hole, and is threadedly connected to the connecting threaded hole.

[0016] In one embodiment, the guide plate device further includes an overload detection element disposed on the side of the inlet guide plate away from the spring plate, and configured to issue an overload signal when it is subjected to a pressure greater than or equal to a preset threshold.

[0017] A transport system comprising a guide plate device as described in any of the preceding claims.

[0018] In one embodiment, the transport system includes a lifting conveyor belt extending longitudinally along a first direction, a heating element being disposed inside the lifting conveyor belt, and a guide plate device being disposed at the inlet of the lifting conveyor belt, with the side of the inlet guide plate away from the spring plate facing the surface of the lifting conveyor belt.

[0019] A packaging machine, comprising a transport system as described in any of the preceding claims.

[0020] In the aforementioned guide plate device, when the cigarette packs are conveyed from the horizontal conveyor belt to the inlet of the lifting conveyor belt, they first contact the inlet guide plate. Under the pushing force of subsequent cigarette packs, the packs exert a flipping force on the inlet guide plate, causing it to rotate relative to the fixed support. This rotation of the inlet guide plate relative to the fixed support causes the spring plate to deform relative to the fixed support, thereby applying an elastic force to the inlet guide plate in the opposite direction. This elastic force allows the inlet guide plate to completely adhere to the cigarette pack. In this way, the cigarette packs can be fully compacted, heated, and dried within the lifting beam channel, reducing the phenomenon of poor adhesion leading to popping open or scattering after output, thus ensuring product quality.

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.

[0028] 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.

[0029] 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.

[0030] 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.

[0032] 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.

[0033] One embodiment of this application provides a packaging machine used for assembling cigarettes, wrapping them with inner lining paper, wrapping them with label paper, and finally forming a soft-pack cigarette pack. The packaging machine includes a transport system. After the label paper is glued and wrapped, a semi-finished cigarette pack is formed, which is then transported to the next production stage via the transport system.

[0034] Specifically, the transportation system includes interconnected lifting conveyor belts and horizontal conveyor belts. The lifting conveyor belt extends longitudinally along a first direction X, and the horizontal conveyor belt extends longitudinally along a second direction Y, intersecting with the first direction X. In actual use, the first direction X can be vertical, and the second direction Y can be horizontal. The semi-finished cigarette packs first enter the horizontal conveyor belt for horizontal transport, then enter the lifting conveyor belt for vertical transport, and finally enter the next production stage at the exit of the lifting conveyor belt.

[0035] The lifting conveyor belt is equipped with a heating element. When the semi-finished cigarette pack, formed by the adhesive wrapping of the label paper, passes through the lifting conveyor belt, the heating element inside the belt heats and dries the pack, allowing the adhesive inside to dry quickly and achieving the desired shape.

[0036] During the transition of semi-finished cigarette packs from the horizontal conveyor belt to the vertical conveyor belt, the adhesive inside the packs may not have dried yet, potentially causing the label paper to pop open during transport. Although a guide plate device is installed at the entrance of the vertical conveyor belt, the traditional inlet guide plate often fits completely against the cigarette pack, leaving gaps that cannot be completely smoothed out. These gaps prevent the cigarette packs from contacting the heating plate, thus affecting the yield rate.

[0037] For this purpose, please refer to Figure 1 , Figure 2 and Figure 3 The guide plate device provided in this application includes a fixed bracket 10, an inlet guide plate 11, and a spring plate 12. The fixed bracket 10 serves to fix the entire guide plate device. In actual use, the fixed bracket 10 can be set on the lifting conveyor belt or on other parts of the packaging machine, as long as the guide plate device can be located at the inlet of the lifting conveyor belt.

[0038] The inlet guide plate 11 includes two opposite ends along a first direction X, one end of which is rotatably mounted on a fixed bracket 10 about a rotation axis intersecting the first direction X. A spring plate 12 is located on one side of the inlet guide plate 11 in a second direction Y and includes two opposite ends along the first direction X, one end of which is mounted on the fixed bracket 10, and the other end is connected to the middle of the inlet guide plate 11 or the end furthest from the fixed bracket 10, to provide an elastic force opposite to the external force when the inlet guide plate 11 rotates relative to the fixed bracket 10 under the action of an external force. The second direction Y, the first direction X, and the rotation axis direction intersect each other but are not coplanar.

[0039] When the guide plate device is located at the entrance of the lifting conveyor belt, the entrance guide plate 11 is spaced apart from the conveying surface of the lifting conveyor belt, and the side of the entrance guide plate 11 away from the spring plate 12 faces the surface of the lifting conveyor belt. This allows the cigarette pack to come into contact with the entrance guide plate 11 when it enters the lifting conveyor belt, and be compacted and shaped by the entrance guide plate 11. Finally, the cigarette pack moves along the entrance guide plate 11 into the lifting conveyor belt and continues to be transported along the lifting conveyor belt.

[0040] In actual use, when the cigarette packs are conveyed from the horizontal conveyor belt to the entrance of the lifting conveyor belt, they first come into contact with the entrance guide plate 11. Under the pushing force of subsequent cigarette packs, the packs exert a flipping force on the entrance guide plate 11, causing it to rotate relative to the fixed support 10. This rotation of the entrance guide plate 11 relative to the fixed support 10 causes the spring plate 12 to deform relative to the fixed support 10. The spring plate 12 then applies an elastic force opposite to the external force to the entrance guide plate 11, allowing it to completely adhere to the cigarette pack. In this way, the cigarette packs can be fully compacted, heated, and dried within the lifting beam channel, reducing the likelihood of poor adhesion leading to popping open or scattering after output, thus ensuring product quality.

[0041] In some embodiments of this application, the guide plate device further includes a connector 13. The connector 13 has two opposite ends along the second direction Y. The two ends of the connector 13 abut or connect with the end of the spring plate 12 away from the fixed bracket 10 and the inlet guide plate 11, respectively. The position where the connector 13 abuts or connects with the inlet guide plate 11 is located in the middle of the inlet guide plate 11 or at the end away from the fixed bracket 10. In this way, when the inlet guide plate 11 rotates, it will drive the spring plate 12 to deform through the connector 13, and the deformed spring plate 12 can also output elastic force to the spring plate 12 through the connector 13.

[0042] Furthermore, the connector 13 is configured to be elastically deformable along the second direction Y. Thus, when the inlet guide plate 11 rotates due to the push of the cigarette pack, the inlet guide plate 11 will cause the connector 13 and the spring plate 12 to deform together, and the connector 13 will share part of the force on the spring plate 12, reducing the risk of the spring plate 12 breaking.

[0043] In some embodiments, the spring plate 12 is provided with an adjustment hole, the inlet guide plate 11 is provided with a fixing threaded hole, and the guide plate device further includes an adjustment bolt 16. The adjustment bolt 16 includes a head 17 and a screw 18. The head 17 is located at one end of the screw 18. The screw 18 passes through the adjustment hole and is threadedly connected to the fixing threaded hole. The size of the head 17 is larger than that of the adjustment hole.

[0044] Thus, when the adjusting bolt 16 is rotated, the head 17 of the adjusting bolt 16 will move closer to or further away from the inlet guide plate 11. When the adjusting bolt 16 moves closer to the inlet guide plate 11, the head 17 of the adjusting bolt 16 will drive one end of the spring plate 12 to move closer to the inlet guide plate 11. The spring plate 12 will then push the inlet guide plate 11 to rotate through the connector 13, thereby adjusting the gap between the inlet guide plate 11 and the surface of the lifting conveyor belt, thereby meeting the compaction and shaping requirements of cigarette packs of different sizes.

[0045] In one specific embodiment, the connector 13 is a spring, which is sleeved on the screw 18 of the adjusting bolt 16. In this way, the installation of the spring can be limited by the screw 18, so that the connector 13 does not need to be fixed separately, reducing the number of parts of the guide plate device and reducing the installation steps.

[0046] In some embodiments, the guide plate device further includes a connecting post 19 extending longitudinally along the second direction Y, and the connecting post 19 has a connecting hole. The guide plate device also includes a clamping bolt 21, the spring plate 12 has a mounting hole, and the fixed bracket 10 has a connecting threaded hole. The clamping bolt 21 passes through the mounting hole and the connecting hole and is threadedly connected to the connecting threaded hole. By using the connecting post 19 disposed between the spring plate 12 and the fixed bracket 10, one end of the spring plate 12 can be lifted, so that the spring plate 12 can be made to be parallel to the inlet guide plate 11, so that the inlet guide plate 11 can more easily drive the spring plate 12 to deform when rotating.

[0047] In some embodiments of this application, the guide plate device further includes an overload detection element. The overload detection element is located on the side of the inlet guide plate 11 away from the spring plate 12 and is configured to issue an overload signal when it is subjected to a pressure greater than or equal to a preset threshold. After receiving the overload signal, the main controller of the packaging machine will issue a stop signal to promptly stop the operation of the packaging machine and prevent further losses.

[0048] The above-mentioned guide plate device has at least the following advantages:

[0049] When the cigarette packs are conveyed from the horizontal conveyor belt to the entrance of the lifting conveyor belt, they first come into contact with the entrance guide plate 11. Under the pushing force of subsequent cigarette packs, the packs exert a flipping force on the entrance guide plate 11, causing it to rotate relative to the fixed support 10. This rotation of the entrance guide plate 11 relative to the fixed support 10 causes the spring plate 12 to deform relative to the fixed support 10, thereby applying an elastic force to the entrance guide plate 11 in the opposite direction. This elastic force allows the entrance guide plate 11 to completely adhere to the cigarette packs. In this way, the cigarette packs can be fully compacted, heated, and dried within the lifting beam channel, reducing the occurrence of poor adhesion leading to popping open or scattering after output, thus ensuring product quality.

[0050] 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.

[0051] 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.
