[0054] Embodiment 1

[0055] The embodiment 1 of the utility model discloses a curing barn automatic lifting loading and unloading system for the loading and unloading operation of the tobacco clamp 500. Among them, the tobacco clamp 500 of the utility model is the clamp that can store a certain amount of tobacco leaf 600 in the prior art, through the use of the tobacco clamp 500, the tobacco leaf 600 can be conveniently hung in the curing barn for baking. Of course, the curing barn self-adaptive loading and unloading system disclosed in the embodiment of the utility model is not only suitable for the loading and unloading operation of the tobacco clamp 500, but also can be applied to other devices similar to the tobacco clamp 500 suitable for storing tobacco leaf 600.

[0056] For the convenience of description, the curing barn automatic lifting loading and unloading system disclosed in the embodiment of the utility model is referred to as "loading and unloading system" hereinafter.

[0057] Figure 1 The structure diagram of the exemplary loading and unloading system disclosed in the embodiment of the utility model, Figure 2 For the convenience of description, the curing barn automatic lifting loading and unloading system disclosed in the embodiment of the utility model is referred to as "loading and unloading system" hereinafter. Figure 1 The loading and unloading system shown is arranged in the curing barn for use, and the reference diagram when carrying out the loading and unloading operation of the tobacco clamp 500. In Figure 1 And Figure 2 In the embodiment shown, the loading and unloading system disclosed in the embodiment of the utility model can include a first conveying device 100, a second conveying device 200 and a transfer device 300.

[0058] Referring to Figure 2 As shown, the first conveying device 100 is arranged inside the curing barn to replace the support frame in the existing curing barn, for supporting a certain number of tobacco clamps 500 in sequence inside the curing barn. Further, the first conveying device 100 can also convey the tobacco clamps 500 in the first direction. The first direction of the utility model can be understood as the longitudinal direction of the curing barn.

[0059] Among them, the first conveying device 100 can include the head end and the tail end in the first direction. The head end of the first conveying device 100 can be understood as the end of the first conveying device 100 close to the door of the curing barn, and the tail end of the first conveying device 100 can be understood as the end of the first conveying device 100 away from the door of the curing barn. Among them, the first conveying device 100 can convey the tobacco clamps 500 from the head end to the tail end, or convey the tobacco clamps 500 from the tail end to the head end, so as to convey the tobacco clamps 500 in the first direction.

[0060] Considering that the known tobacco clamp 500 is mostly rectangular and long strip-shaped, therefore, as Figure 3As shown, the first conveying device 100 can include two first conveying mechanisms 101 arranged side by side along the length direction of the tobacco holder 500, and each of the two first conveying mechanisms 101 includes a first conveying surface 102 movable along the first direction. In this way, only the two ends of the tobacco holder 500 in the length direction need to be supported on the first conveying surfaces 102 of the two first conveying mechanisms 101, and the tobacco holder 500 can be conveyed along the first direction by the two first conveying mechanisms 101.

[0061] The first conveying mechanism 101 can be a belt or chain conveyor, as long as it can horizontally convey the tobacco holder 500 along the first direction, which is not limited herein.

[0062] Referring to Figure 2 As shown, the second conveying device 200 is arranged outside the leading end of the first conveying device 100, specifically at the door of the curing barn, so as to provide the first conveying device 100 with the tobacco holder 500 to be stored in the curing barn, or output the tobacco holder 500 from the first conveying device 100 to be taken out of the curing barn. Further, the second conveying device 200 can convey the tobacco holder 500 along the height direction, so as to provide the first conveying device 100 with the tobacco holder 500, or output the tobacco holder 500 from the first conveying device 100.

[0063] The second conveying device 200 can include a leading end and a trailing end in the height direction. The leading end of the second conveying device 200 can be understood as the end of the second conveying device 200 close to the ground, and the trailing end of the second conveying device 200 can be understood as the end of the second conveying device 200 away from the ground. The second conveying device 200 can convey the tobacco holder 500 from the leading end to the trailing end, or from the trailing end to the leading end, so as to convey the tobacco holder 500 along the height direction. In addition, the trailing end of the second conveying device 200 is aligned with the leading end of the first conveying device 100.

[0064] Correspondingly, based on the known fact that the tobacco holder 500 is mostly rectangular and long strip-shaped, therefore, as Figure 4As shown, the second conveying device 200 can also include two second conveying mechanisms 201 arranged side by side along the length direction of the tobacco holder 500, and each of the two second conveying mechanisms 201 includes a second conveying surface 202 movable along the height direction. Moreover, the second conveying surface 202 of each of the two second conveying mechanisms 201 is provided with a plurality of substantially horizontal support members 203 arranged side by side along the height direction on the corresponding second conveying surface 202. In this way, the tobacco holder 500 only needs to be supported at both ends thereof along the length direction on the support members 203 at the same height position on the second conveying surface 202 of the two second conveying mechanisms 201, and then the tobacco holder 500 can be conveyed along the height direction by the two second conveying mechanisms 201. The support members 203 can be horizontal support plates arranged on the second conveying surface 202 of each second conveying mechanism 201.

[0065] The second conveying mechanism 201 can also be a belt conveyor or a chain conveyor, as long as it can horizontally convey the tobacco holder 500 along the first direction, which is not limited herein. In particular, the second conveying mechanism 201 can be the structure described in Embodiment 2 of the present application, so that the conveying distance thereof along the height direction is variable, thereby enabling the second conveying device 200 to cooperate with the first conveying device 100 at different height positions to transfer the tobacco holder 500.

[0066] Referring to Figure 2 As shown, the transfer device 300 is arranged between the first conveying device 100 and the second conveying device 200, specifically between the leading end of the first conveying device 100 and the trailing end of the second conveying device 200, to transfer the tobacco holder 500 between the first conveying device 100 and the second conveying device 200, i.e., to transfer the tobacco holder 500 conveyed by the second conveying device 200 to the first conveying device 100, or to transfer the tobacco holder 500 on the first conveying device 100 to the second conveying device 200.

[0067] Based on the above arrangement, when the tobacco holder 500 is loaded or unloaded, the tobacco holder 500 can be sequentially and orderly stored in the barn or taken out from the barn by the cooperation of the first conveying device 100, the second conveying device 200 and the transfer device 300.

[0068] Specifically, when it is necessary to store the cigarette clip 500 in the curing barn, the cigarette clip 500 to be stored can be conveyed by the second conveying device 200 along the height direction to the tail end of the second conveying device 200 to align with the head end of the first conveying device 100; then, the transfer device 300 transfers the cigarette clip 500 located at the tail end of the second conveying device 200 to the head end of the first conveying device 100, and then the first conveying device 100 can be used to convey the cigarette clip 500 in the first direction inward, that is, into the curing barn; in this way, multiple cigarette clips 500 to be stored can be continuously transferred to the first conveying device 100, and multiple cigarette clips 500 are arranged along the depth direction of the curing barn on the first conveying device 100 in the curing barn.

[0069] When it is necessary to remove the cigarette clips 500 from the curing room, the first conveying device 100 conveys the multiple cigarette clips 500 supported by itself sequentially towards its head in the first direction. During this process, the transfer device 300 sequentially transfers the cigarette clips 500 that have reached the head of the first conveying device 100 to the tail of the second conveying device 200. Then, the second conveying device 200 can sequentially convey the cigarette clips 500 from the first conveying device 100 down in the height direction for removal.

[0070] As can be seen, the loading and unloading system disclosed in this utility model embodiment, through the cooperation of the first conveying device 100, the second conveying device 200 and the transfer device 300, can automatically transfer the tobacco clip 500 to the curing barn or remove the tobacco clip 500 from the curing barn, thereby helping to improve the automation level of the loading and unloading operation of the tobacco clip 500, and helping to reduce the labor cost of the loading and unloading operation of the tobacco clip 500 and the safety hazards caused by manual climbing operations.

[0071] In some embodiments, the transfer device 300 may be constructed in the manner described below, but is not limited to.

[0072] like Figure 4 and Figure 5 As shown, the transfer device 300 may include two transfer mechanisms 301 arranged side by side at intervals along the length of the cigarette clip 500. Each transfer mechanism 301 includes a transfer member 3011 that can reciprocate along a first direction.

[0073] Thus, when it is necessary to transfer the cigarette clip 500 located at the tail end of the second conveying device 200 to the head end of the first conveying device 100, the transfer members 3011 of the two transfer mechanisms 301 are first moved to the outside of the cigarette clip 500, that is, away from the first conveying device 100. Then, the transfer members 3011 of the two transfer mechanisms 301 are moved synchronously towards the direction of the first conveying device 100, so that the cigarette clip 500 can be pushed from the second conveying device 200 to the first conveying device 100.

[0074] Correspondingly, when it is necessary to transfer the cigarette clip 500 located at the head end of the first conveying device 100 to the tail end of the second conveying device 200, first move the transfer parts 3011 of the two transfer mechanisms 301 to the inside of the cigarette clip 500, that is, away from the second conveying device 200, and then move the transfer parts 3011 of the two transfer mechanisms 301 synchronously towards the direction of the second conveying device 200, so that the cigarette clip 500 can be pushed from the first conveying device 100 to the second conveying device 200. The operation is simple and convenient.

[0075] The transfer component 3011 used to push the cigarette clip 500 can be, but is not limited to, for... Figure 5 The transfer column is shown. Furthermore, the movement of the transfer member 3011 along the first direction can be achieved by providing a conventional linear drive device 3012. Of course, the device for driving the transfer member 3011 to move along the first direction can also be... Figure 5 In the chain conveyor shown, it is only necessary to fix the transfer member 3011 to one side of the chain conveyor. Alternatively, in other embodiments of this invention, the transfer device 300 may have other structural forms where possible; for example, the transfer device 300 may also be a robotic arm capable of gripping and transferring the cigarette clip 500.

[0076] In some embodiments, combined with Figure 1 and Figure 2 As shown, the loading and unloading system may further include a third conveying device 400. The third conveying device 400 is positioned outside the second conveying device 200, i.e., on the side of the second conveying device 200 away from the curing barn. The third conveying device 400 provides the second conveying device 200 with tobacco clips 500 to be stored in the curing barn, or outputs tobacco clips 500 from the second conveying device 200 that need to be removed from the curing barn. Furthermore, the third conveying device 400 can convey the tobacco clips 500 along a first direction to provide tobacco clips 500 to the second conveying device 200, or output tobacco clips 500 from the second conveying device 200.

[0077] The third conveying device 400 can also include a head end and a tail end in the first direction. The head end of the third conveying device 400 can be understood as the end of the third conveying device 400 away from the curing oven, and the tail end of the third conveying device 400 can be understood as the end of the third conveying device 400 closer to the curing oven. The third conveying device 400 can convey the cigarette clip 500 from its head end to its tail end, or from its tail end to its head end, to achieve the conveying of the cigarette clip 500 in the first direction. Furthermore, the tail end of the third conveying device 400 is aligned with the head end of the second conveying device 200.

[0078] Correspondingly, based on the fact that most known cigarette clips are rectangular strips, therefore, asFigure 6 As shown, the third conveying device 400 can include two third conveying mechanisms 401 arranged side by side along the length direction of the tobacco holder 500, and each of the two third conveying mechanisms 401 includes a third conveying surface 402 movable along the first direction. In this way, only the two ends of the tobacco holder 500 in the length direction need to be supported on the third conveying surfaces 402 of the two third conveying mechanisms 401, and the tobacco holder 500 can be conveyed along the first direction by the two third conveying mechanisms 401.

[0079] It should be understood that the third conveying mechanism 401 can be a belt conveyor or a chain conveyor, as long as it can horizontally convey the tobacco holder 500 along the first direction, which is not limited herein.

[0080] It should be understood that in the case where the third conveying device 400 includes two third conveying mechanisms 401, the two third conveying mechanisms 401 can be arranged in the same way as the two second conveying mechanisms 201 of the second conveying device 200. Figure 1 As shown, the two second conveying mechanisms 201 of the second conveying device 200 should be arranged outside the two third conveying mechanisms 401, i.e., on the side where the two third conveying mechanisms 401 face away from each other. The horizontal distance between the third conveying surfaces 402 of the two third conveying mechanisms 401 is less than the horizontal distance between the support members 203 at the same height position on the two second conveying mechanisms 201. Moreover, both the horizontal distance between the third conveying surfaces 402 of the two third conveying mechanisms 401 and the horizontal distance between the support members 203 at the same height position on the two second conveying mechanisms 201 are less than the length of the tobacco holder 500, so that the tobacco holder 500 can be supported on the third conveying surfaces 402 of the two third conveying mechanisms 401 and on the support members 203 at the same height position on the two second conveying mechanisms 201.

[0081] Based on the above arrangement, in the operation of storing the tobacco holder 500 inside the curing barn, for a single tobacco holder 500, after the relevant personnel places the tobacco holder 500 at the leading end of the third conveying device 400 to convey the tobacco holder 500 to the trailing end of the third conveying device 400 by the third conveying device 400, the support members 203 at the same height position on the two second conveying mechanisms 201 of the second conveying device 200 will move upward along the height direction from below the tobacco holder 500 to lift the tobacco holder 500 from the third conveying device 400 by the support members 203 and convey the tobacco holder 500 along the height direction to the trailing end of the second conveying device 200, so as to push the tobacco holder 500 onto the first conveying device 100 by the transfer device 300.

[0082] In the operation of taking the tobacco clips 500 out of the curing barn, for a single tobacco clip 500, when the tobacco clip 500 on the second conveying device 200 reaches the tail end thereof, the tobacco clip 500 can be carried on the third conveying surfaces 402 of the two third conveying mechanisms 401 of the third conveying device 400, so as to convey the tobacco clip 500 out by means of the third conveying device 400.

[0083] Such design realizes the transfer of the tobacco clip 500 between the second conveying device 200 and the third conveying device 400 without arranging a device similar to the transfer device 300 between the second conveying device 200 and the third conveying device 400.

[0084] In some embodiments, in combination with the content shown in Figure 3 and Figure 6 , the first conveying surfaces 102 of the two first conveying mechanisms 101 of the first conveying device 100 and the third conveying surfaces 402 of the two third conveying mechanisms 401 of the third conveying device 400 can all be provided with a plurality of partition blocks 700 arranged in sequence and at intervals along the conveying path.

[0085] Through the arrangement of the partition blocks 700, a single tobacco clip 500 can be carried between the adjacent two partition blocks 700 on the corresponding conveying surface, so as to avoid the collision between different tobacco clips 500 when the corresponding conveying mechanism conveys the tobacco clip 500.

[0086] In some embodiments, in combination with the content shown in Figure 6 , the third conveying device 400 can further include a conveying bracket 403. The two third conveying mechanisms 401 are arranged on the conveying bracket 403. Meanwhile, the conveying bracket 403 can be provided with a moving member 404, so that the third conveying device 400 has a moving capability, thereby facilitating the adjustment of the position of the third conveying device 400 as needed. The moving member 404 can be a roller arranged at the bottom of the conveying bracket 403.

[0087] Meanwhile, the conveying bracket 403 can be further provided with an adjustable foot cup 405, which can be arranged at the bottom of the conveying bracket 403 and located beside the moving member 404. When the third conveying device 400 is moved to the target position by means of the moving member 404, the adjustable foot cup 405 can be adjusted to support the entire third conveying device 400 on the ground by means of the adjustable foot cup 405, so as to avoid the easy displacement of the third conveying device 400.

[0088] In some embodiments, in combination with the content shown in Figure 1 , the loading and unloading system can further include a control box 800. The control box 800 can be arranged on the third conveying device 400, specifically on the side of the conveying bracket 403 away from the curing barn.

[0089] The first conveying device 100, the second conveying device 200, the third conveying device 400 and the transfer device 300 are in communication connection with the control box 800, so that the first conveying device 100, the second conveying device 200, the third conveying device 400 and the transfer device 300 are linked together, and thus the relevant personnel can control the first conveying device 100, the second conveying device 200, the third conveying device 400 and the transfer device 300 by means of the control box 800, so as to realize automatic loading and unloading of the tobacco clips 500. The first conveying device 100, the second conveying device 200, the third conveying device 400 and the transfer device 300 are in communication connection with the control box 800 based on the communication connection technology known in the prior art, and thus no further description is given herein.

[0090] It is worth noting that, considering the limited internal space of the curing barn, it may not be suitable to separately provide the first conveying device 100 with a driving device for driving the movement of the conveying belt or conveying chain in the first conveying mechanism 101. Therefore, the driving device for driving the movement of the conveying belt or conveying chain in the first conveying mechanism 101 can be arranged outside the curing barn, especially at an appropriate position on the second conveying device 200, which facilitates the optimization of the structural design of the entire loading and unloading system while ensuring reliable power transmission.

[0091] Embodiment 2

[0092] On the basis of embodiment 1, embodiment 2 of the present application provides another curing barn automatic lifting loading and unloading system, which is different from embodiment 1 in that, as shown in Figure 1 or Figure 2 The loading and unloading system provided by the present embodiment comprises a plurality of first conveying devices 100, and the plurality of first conveying devices 100 are arranged in sequence along the height direction. The first conveying device 100 at each height position is adapted to support a certain number of tobacco clips 500 inside the curing barn, so as to realize the rational use of the limited space inside the curing barn.

[0093] On this basis, in order to enable the second conveying device 200 to cooperate with the first conveying device 100 at different height positions to realize the transfer of the tobacco clips 500, the present application further improves the structure of the second conveying device 200 and the setting position of the transfer device 300, so that the conveying distance of the second conveying device 200 can be adjusted, and the position of the transfer device 300 can change with the change of the conveying distance of the second conveying device 200, so that the second conveying device 200 can cooperate with the first conveying device 100 at different height positions to realize the transfer of the tobacco clips 500.

[0094] Specifically, in embodiment 2 of the present application, as shown in Figure 4As shown, the transfer device 300 is arranged at the tail end of the second conveying device 200, specifically, the top end of the two second conveying mechanisms 201, so that when the conveying distance of the two second conveying mechanisms 201 changes, the position of the transfer device 300 in the height direction changes accordingly to cooperate with the first conveying device 100 at different height positions.

[0095] Based on the same structure of the two second conveying mechanisms 201 constituting the second conveying device 200, the structure of the second conveying mechanism 201 will be described in detail below taking a single second conveying mechanism 201 as an example.

[0096] As shown in the combination Figure 7 and Figure 8 , the second conveying mechanism 201 can include a fixed support 10, a movable support 20, and a conveying assembly 30.

[0097] The fixed support 10 and the movable support 20 are arranged in sequence in the height direction. Moreover, the movable support 20 can move reciprocally in the height direction to approach or move away from the fixed support 10. Among them, referring to Figure 4 As shown, the reciprocating movement of the movable support 20 in the height direction can be realized by additionally adding a linear drive mechanism 60 for driving the movable support 20 to move in the height direction, such as a pneumatic cylinder, an electric push rod, and a linear module, etc.

[0098] Among them, the two transfer mechanisms 301 in the transfer device 300 described in the foregoing embodiment 1 can be arranged on the movable support 20 of the corresponding second conveying mechanism 201.

[0099] The conveying assembly 30 is arranged between the fixed support 10 and the movable support 20 to realize the conveying of the cigarette holder 500 in the height direction.

[0100] Specifically, as shown in Figure 8 or Figure 9 , the conveying assembly 30 can include a first transmission wheel 31, a second transmission wheel 32, a third transmission wheel 33, a floating wheel 34, a flexible transmission element 35, and a driving component 36.

[0101] Among them, the second transmission wheel 32 and the third transmission wheel 33 are arranged opposite to the first transmission wheel 31 in the height direction, for example, the first transmission wheel 31 can be rotatably arranged on the fixed support 10, and the second transmission wheel 32 and the third transmission wheel 33 can be rotatably arranged on the movable support 20. Moreover, the second transmission wheel 32 and the third transmission wheel 33 can move reciprocally in the height direction to approach or move away from the first transmission wheel 31 synchronously.

[0102] A floating wheel 34 is disposed between the first transmission wheel 31, the second transmission wheel 32, and the third transmission wheel 33. The second transmission wheel 32 and the third transmission wheel 33 are distributed on both sides of the floating wheel 34. Furthermore, the floating wheel 34 can reciprocate along the height direction to move closer to or further away from the first transmission wheel 31.

[0103] Among them, reference Figure 8 As shown, the reciprocating movement of the floating wheel 34 can be achieved by setting a movable drive assembly 40 on the movable support 20, which is capable of outputting reciprocating motion along the height direction, and rotatably setting the floating wheel 34 at the output end of the movable drive assembly 40. The movable drive assembly 40 can be a linear module set on the movable support 20 and corresponding one-to-one with the conveying assembly 30.

[0104] The flexible transmission element 35 is sequentially wound around the first transmission wheel 31, the second transmission wheel 32, the floating wheel 34, and the third transmission wheel 33 to form a tensioned annular closed structure. Furthermore, the first transmission wheel 31, the second transmission wheel 32, and the third transmission wheel 33 are all located inside the flexible transmission element 35, while the floating wheel 34 is located outside the flexible transmission element 35. Here, "inner side" refers to the interior of its self-closed annular path, and "outer side" refers to the exterior of its self-closed annular path.

[0105] The flexible transmission elements 35 between the first transmission wheel 31 and the second transmission wheel 32, and between the first transmission wheel 31 and the third transmission wheel 33, can all serve as conveying sections for conveying the cigarette clip 500. In this embodiment, referring to... Figure 9 As shown, the outer side of the flexible transmission element 35 between the first transmission wheel 31 and the second transmission wheel 32 can be used as the second conveying surface 202. In this case, the support member 203 described in the aforementioned embodiment 1 can be set on the flexible transmission element 35 between the first transmission wheel 31 and the second transmission wheel 32.

[0106] The flexible transmission element 35 can be a known device such as a conveyor belt (e.g., a synchronous belt) or a conveyor chain. When the flexible transmission element 35 is a conveyor belt, the first transmission wheel 31, the second transmission wheel 32, the third transmission wheel 33, and the floating wheel 34 can all be pulleys; when the flexible transmission element 35 is a conveyor chain, the first transmission wheel 31, the second transmission wheel 32, the third transmission wheel 33, and the floating wheel 34 can all be sprockets.

[0107] Reference Figure 10 As shown, the drive component 36 is driveably connected to any one of the first drive wheel 31, the second drive wheel 32, and the third drive wheel 33, so as to drive the drive wheel connected to it to rotate, thereby providing power for the flexible transmission element 35 to move along its own closed loop path. For example, the drive component 36 can be an electric motor.

[0108] Thus, when the driving component 36 drives any one of the first transmission wheel 31, the second transmission wheel 32, and the third transmission wheel 33 to rotate, the flexible transmission element 35 can move along its own closed loop path, so that the cigarette clip 500 supported on the support member 203 can be moved along the height direction through the movement of the flexible transmission element 35.

[0109] Furthermore, since the second drive wheel 32, the third drive wheel 33, and the floating wheel 34 can all reciprocate along the height direction to move closer to or further away from the first drive wheel 31, when it is necessary to change the conveying distance of the entire second conveying mechanism 201, it is only necessary to reasonably control the movement of the second drive wheel 32, the third drive wheel 33, and the floating wheel 34 along the height direction.

[0110] Specifically, when it is necessary to shorten the conveying distance of the second conveying mechanism 201 so that the second conveying device 200 can cooperate with the lower-positioned first conveying device 100, refer to Figure 11 and Figure 12 As shown, the second drive wheel 32 and the third drive wheel 33 are brought closer to the first drive wheel 31 in the height direction. Specifically, the movable bracket 20 is brought closer to the fixed bracket 10 to shorten the length of the flexible transmission element 35 between the first drive wheel 31 and the second drive wheel 32, and between the first drive wheel 31 and the third drive wheel 33. This shortens the conveying distance of the second conveying mechanism 201. Correspondingly, the transfer device 300 is also lowered to match the first conveying device 100 at the target position. During this process, the floating wheel 34 is brought closer to the first drive wheel 31 in the height direction under the drive of the moving drive assembly 40, so that the flexible transmission element 35 is always in a tensioned state. This ensures that even when the length of the flexible transmission element 35 between the first drive wheel 31 and the second drive wheel 32, and between the first drive wheel 31 and the third drive wheel 33 is shortened, the flexible transmission element 35 can still move along its own closed loop path to convey the cigarette clip 500.

[0111] Conversely, when it is necessary to extend the conveying distance of the second conveying mechanism 201, refer to Figure 7 or Figure 8As shown, the second transmission wheel 32 and the third transmission wheel 33 are simultaneously moved away from the first transmission wheel 31 along the height direction, specifically, the movable support 20 is moved away from the fixed support 10, so as to lengthen the length of the flexible transmission element 35 between the first transmission wheel 31 and the second transmission wheel 32 and between the first transmission wheel 31 and the third transmission wheel 33, thereby achieving the purpose of lengthening the conveying distance of the second conveying mechanism 201, and correspondingly, the transfer device 300 is also lifted to adapt to the first conveying device 100 at the target position; in this process, the floating wheel 34 is simultaneously moved away from the first transmission wheel 31 along the height direction under the drive of the movement driving assembly 40, so that the flexible transmission element 35 is always in a tension state, thereby ensuring that the flexible transmission element 35 can also move along the closed loop path thereof in the case that the length of the flexible transmission element 35 between the first transmission wheel 31 and the second transmission wheel 32 and between the first transmission wheel 31 and the third transmission wheel 33 is lengthened, so as to convey the tobacco clip 500.

[0112] It can be seen that the second conveying mechanism 201 disclosed in Embodiment 2 of the present application can flexibly adjust the conveying distance of the entire second conveying mechanism 201 based on the position changes of the second transmission wheel 32, the third transmission wheel 33 and the floating wheel 34 which can move reciprocally along the height direction. This design enables the second conveying device 200 to cooperate with the first conveying device 100 at multiple different height positions to complete the transfer of the tobacco clip 500.

[0113] In some embodiments, the second conveying mechanism 201 can further include a detection component 50. The detection component 50 is configured to detect the movement direction of the second transmission wheel 32 and the third transmission wheel 33, and control the floating wheel 34 to move along the height direction according to the detection result, so that the movement direction of the floating wheel 34 is consistent with the movement direction of the second transmission wheel 32 and the third transmission wheel 33.

[0114] In order to further optimize the structural design of the second conveying mechanism 201, the detection component 50 can include a first micro switch 51 and a second micro switch 52 arranged at the output end of the movement driving assembly 40. Figure 13 As shown, the first micro switch 51 and the second micro switch 52 are arranged in sequence along the height direction, the first micro switch 51 is elastically retained at a position not contacting any other component by a first elastic member 53, and the second micro switch 52 is elastically retained at a position not contacting any other component by a second elastic member 54.

[0115] In addition, the distance from the first micro switch 51 to the first transmission wheel 31 is greater than the distance from the second micro switch 52 to the first transmission wheel 31, that is, the first micro switch 51 is located above the second micro switch 52. At the same time, the first micro switch 51 and the second micro switch 52 are both in communication connection with the movement driving assembly 40.

[0116] Based on the above setting, since the moving driving assembly 40 is arranged on the movable support 20 which can move along the height direction, when the movable support 20 moves along the height direction to approach or move away from the fixed support 10, so that the second transmission wheel 32 and the third transmission wheel 33 on the movable support 20 approach or move away from the first transmission wheel 31 on the fixed support 10, the first elastic member 53 and the second elastic member 54 connected with the first micro switch 51 and the second micro switch 52 will be elastically deformed correspondingly, so that the first micro switch 51 and the second micro switch 52 are triggered separately, so that the movement direction of the movable support 20, that is, the movement direction of the second transmission wheel 32 and the third transmission wheel 33, is judged based on the triggering of the micro switch, and then the floating wheel 34 is moved in the corresponding direction by controlling the moving driving assembly 40.

[0117] Specifically, when the movable support 20 approaches the fixed support 10, the second elastic member 54 connected to the second micro switch 52 will contract, and the first elastic member 53 connected to the first micro switch 51 will elongate, at this time, the second micro switch 52 will be in contact with other components, specifically the related components of the moving driving assembly 40, to trigger the second micro switch 52, so that the movement direction of the movable support 20 is detected, and the first micro switch 51 is still not in contact with other components and is not triggered; at this time, the second micro switch 52 can send a signal to the moving driving assembly 40 to control the moving driving assembly 40 to drive the floating wheel 34 to move in the direction of approaching the first transmission wheel 31, so that the movement direction of the floating wheel 34 is consistent with the movement direction of the second transmission wheel 32 and the third transmission wheel 33.

[0118] Correspondingly, when the movable support 20 moves away from the fixed support 10, the first elastic member 53 connected to the first micro switch 51 will contract, and the second elastic member 54 connected to the second micro switch 52 will elongate, at this time, the first micro switch 51 will be in contact with other components, specifically the related components of the moving driving assembly 40, to trigger the first micro switch 51, so that the movement direction of the movable support 20 is detected, and the second micro switch 52 is still not in contact with other components and is not triggered; at this time, the first micro switch 51 can send a signal to the moving driving assembly 40 to control the moving driving assembly 40 to drive the floating wheel 34 to move in the direction of moving away from the first transmission wheel 31, so that the movement direction of the floating wheel 34 is consistent with the movement direction of the second transmission wheel 32 and the third transmission wheel 33.

[0119] In the embodiment of the utility model, in the case that the moving driving assembly 40 is a linear module, continuing to refer to Figure 13The output end of the moving driving assembly 40 refers to a sliding table 41 that can reciprocate in the height direction. At this time, the floating wheel 34 can rotate on the sliding table 41 of the linear module. Correspondingly, the first micro switch 51 and the second micro switch 52 are also elastically retained on the sliding table 41 under the action of the corresponding elastic members.

[0120] In some embodiments, with reference to Figure 8 or Figure 12 As shown, the first transmission wheel 31 can have two, and the two first transmission wheels 31 are arranged side by side. The axes of the two first transmission wheels 31 are parallel to the line between the axes of the second transmission wheel 32 and the third transmission wheel 33. In this way, the flexible transmission elements 35 between one of the first transmission wheels 31 and the second transmission wheel 32 and between the other first transmission wheel 31 and the third transmission wheel 33 can remain parallel, so that both of the parallel flexible transmission elements 35 can be used to transport objects, such as a cigarette clip 500.

[0121] In some embodiments, the conveying mechanism can also include a plurality of conveying assemblies 30, and the plurality of conveying assemblies 30 can be arranged side by side for use to improve the conveying capacity and reliability of the conveying mechanism when conveying objects. For example, the utility model discloses Figure 7 two conveying assemblies 30 arranged side by side.

[0122] It can be understood that when the conveying assembly 30 is multiple, the plurality of conveying assemblies 30 can share one driving part 36 as a power source, thereby reducing the cost.

[0123] Among them, when the moving driving assembly 40 is a linear module and the conveying assembly 30 is multiple, the plurality of moving driving assemblies 40 can also share one driving device, such as a motor, for forcing the sliding tables 41 of the plurality of moving driving assemblies 40 to move in the height direction, thereby reducing the cost.

[0124] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
