Description

Technical Field

[0002] Tobacco packaging machines are core equipment in the tobacco production process. As the direct packaging carrier for tobacco products, the feeding process is crucial for the efficient operation of tobacco packaging machines. Existing tobacco packaging machines are generally equipped with two feeding channels, but the orientation of the small hard boxes on these two feeding channels is 180 degrees apart, which places higher demands on the accuracy and continuity of the feeding process.

[0061] Referring to Figures 1 to 10 The embodiment provides a feeding device for a tobacco packaging machine, which is used for feeding material 13 to a first feeding channel and a second feeding channel of an external processing equipment, and comprises a feeding mechanism 2, a separating mechanism 4, a carrying mechanism 5, a reversing mechanism 6, and a detection mechanism (not shown in the figure).

[0062] In the embodiment, the feeding device for tobacco packaging machine further comprises a first frame body 1 and a second frame body 3. The first frame body 1 is provided with at least one storage stack 11, and the storage stack 11 is configured to carry a plurality of material boxes 12. Each material box 12 contains a plurality of materials 13. The second frame body 3 is arranged between the first frame body 1 and the processing equipment. In addition, the feeding mechanism 2 is arranged on the first frame body 1, and the separating mechanism 4, the carrying mechanism 5, the reversing mechanism 6 and the detection mechanism are arranged on the second frame body 3. It should be pointed out that the processing equipment is the tobacco packaging machine mentioned above, and the material 13 is the hard small box mentioned above, which will not be described in detail.

[0063] Specifically, the feeding mechanism 2 is configured to feed the material box 12 carrying the material 13 on the storage stack 11 to the separating mechanism 4. The separating mechanism 4 is configured to separate the material 13 in the material box 12 received by the separating mechanism 4. The carrying mechanism 5 is configured to receive the material 13 separated by the separating mechanism 4. The detection mechanism is configured to detect whether the first feeding channel and the second feeding channel are out of material, and feed back the detection result to the carrying mechanism 5. The carrying mechanism 5 can feed the material 13 when the first feeding channel and the second feeding channel are out of material. The feeding device for tobacco packaging machine further comprises a reversing mechanism 6, and the carrying mechanism 5 can carry the material 13 to be fed to the reversing mechanism 6 to adjust the posture of the material 13 through the reversing mechanism 6 to match the different feeding posture requirements of the first feeding channel and / or the second feeding channel.

[0064] As can be seen from the above, the working principle of the feeding device for tobacco packaging machine is as follows:

[0065] Firstly, the feeding mechanism 2 grabs the material box 12 and transports it to the separating mechanism 4, and at the same time, the feeding mechanism 2 detects the front and back of the material 13 in the material box 12. Then, the separating mechanism 4 receives the material box 12 transported by the feeding mechanism 2, and separates the material box 12 from the material 13 loaded in it. Then, the carrying mechanism 5 carries the separated material 13. In this process, the detection mechanism monitors the state of the material 13 on the first feeding channel and the second feeding channel of the processing equipment in real time, and the detection mechanism feeds back the result to the carrying mechanism 5. The carrying mechanism 5 directly carries the material 13 to the first feeding channel according to the feedback, or carries the material 13 to the reversing mechanism 6, and then carries the material 13 to the second feeding channel after the material 13 is reversed by the reversing mechanism 6. Finally, the above steps are repeated several times, which can realize the automatic and continuous feeding of the processing equipment.

[0066] In this way, the tobacco packaging machine replaces the manual carrying process of the material box 12 by the feeding device through the feeding mechanism 2, significantly reduces the labor intensity of workers, avoids the efficiency loss caused by multi-person cooperation, and greatly improves the feeding speed. Secondly, through the cooperation of the separation mechanism 4, the reversing mechanism 6 and the detection mechanism, the accurate adjustment of the material 13 in the forward and reverse directions and the distribution of the material 13 in the first feeding channel and the second feeding channel on the processing equipment are realized, which can avoid the common omissions such as reverse installation and reverse installation of the material 13 in manual operation, and ensure the stability of the subsequent automatic packaging process and product quality. In addition, the automatic process reduces manual intervention and avoids management confusion caused by human operation on site.

[0067] It should be noted that the feeding mechanism 2 is preferably a multi-axis robot in the prior art, which has high flexibility and accurate positioning capability, can freely move in three-dimensional space to adapt to the grabbing needs of the material box 12 at different positions on the storage stack 11, and improve the grabbing efficiency and accuracy. Of course, the feeding structure can also select other structures with grabbing and transfer functions in the prior art, such as horizontal and vertical movement of the material box 12 through linear guide rails and servo motors, combined with pneumatic or mechanical clamps to complete grabbing; for example, the material box 12 on the storage stack 11 is rotated to the specified position in turn, and then transferred by a simple grabbing mechanism, so this embodiment does not make specific requirements and limitations.

[0068] It should also be noted that the feeding mechanism 2 also has a function for detecting the front and back of the material 13 to prevent the feeding mechanism 2 from grabbing the material box 12 loaded with the reverse material 13 on the storage stack 11. The above detection function can be realized by a detection component, and the optional detection component includes but is not limited to a vision sensor, a photoelectric sensor, etc. In this embodiment, a vision sensor is preferred, which can accurately judge the front and back direction by shooting the image of the material 13 and recognizing the pattern, logo or structural difference on the surface of the material 13 through image processing algorithm.

[0069] It should also be noted that the detection mechanism can adopt detection components respectively arranged at the first feeding channel and the second feeding channel, and the types of the detection components include but are not limited to existing photoelectric sensors, vision detection components, etc., which will not be described in detail.

[0070] In this embodiment, the separation mechanism 4 includes a bearing assembly 41 and a grabbing assembly 42. The bearing assembly 41 is configured to support and fix a plurality of materials 13 in the same material box 12. The grabbing assembly 42 is configured to grab the material box 12 supported by the bearing assembly 41 and move the material box 12 in the horizontal direction, so as to separate the material box 12 and the plurality of materials 13.

[0071] When separating, the plurality of materials 13 in the same magazine 12 are first supported and fixed by the bearing assembly 41 to ensure that the materials 13 remain stable during the separation process. Then, the grabbing assembly 42 grabs the magazine 12 and moves the magazine 12 in the horizontal direction, so that the magazine 12 and the materials 13 supported by the bearing assembly 41 are relatively displaced, thereby realizing efficient separation of the magazine 12 and the internal materials 13.

[0072] The bearing assembly 41 includes a first bearing plate 411, a pressing member 412, and a second bearing plate 413. The first bearing plate 411 is arranged on the first frame body 1 and is used to bear the plurality of materials 13. The pressing member 412 can slide in the vertical direction and is located directly above the first bearing plate 411, so that the pressing member 412 can press the plurality of materials 13 borne by the first bearing plate 411, thereby being able to fix the plurality of materials 13. The second bearing plate 413 can slide in the vertical direction and can slide to be flush with the first bearing plate 411 to form a bearing station for bearing the plurality of materials 13. In combination with the actual application scenario, after the magazine 12 and the plurality of materials 13 are separated, the second bearing plate 413 slides upward to be flush with the first bearing plate 411 to bear the part of the plurality of materials 13 originally located in the magazine 12.

[0073] It can be understood that the second bearing plate 413 can timely fill the support vacancy at the bottom of the materials 13 after the magazine 12 is separated. For the cigarette box and other light and thin materials 13 that are easy to deform, the materials 13 can be effectively prevented from scattering, stacking disorder, or local collapse due to the loss of the magazine 12, so that the materials 13 can always remain in an orderly and stable state during the separation process, thereby reducing the rate of defective products caused by improper operation and improving product quality.

[0074] It should be noted that the driving structure of the pressing member 412 and the second bearing plate 413 can be any linear driving mechanism in the prior art, such as a pneumatic cylinder or a linear module, and the present embodiment does not make specific requirements and limitations on this.

[0075] In particular, the grabbing assembly 42 includes a positioning baffle 421 and a suction member 422. The positioning baffle 421 can slide in the horizontal direction and vertically abut the magazine 12. The suction member 422 can slide in the horizontal direction and can pass through the positioning baffle 421 and adsorb the magazine 12.

[0076] In this way, by positioning the baffle 421 to slide in the horizontal direction and vertically abut the material box 12, the position of the material box 12 can be accurately defined, avoiding deviation or shaking of the material box 12 during grabbing, so as to ensure the consistent posture of the material box 12 each time it is grabbed, improve the positioning accuracy, and reduce the risk of jamming or damage due to position deviation. In addition, the structure in which the suction member 422 passes through the positioning baffle 421 to adsorb the material box 12 realizes the cooperative matching of the positioning and grabbing actions. The positioning baffle 421 positions the material box 12 at the same time, provides an accurate grabbing path for the suction member 422, so that it can be directly aligned with the surface of the material box 12, and enhances the reliability of grabbing.

[0077] It should be noted that the driving structure of the positioning baffle 421 and the suction member 422 can select any linear driving mechanism in the prior art, such as a pneumatic cylinder, a linear module, etc., and the present embodiment does not make specific requirements and limitations on this. It should also be noted that the suction member 422 is preferably a vacuum adsorption structure, and the number and arrangement position of the suction member 422 can be set according to the actual application scene, so no further description is given. In addition, the components moving in a straight line in the following text are selected according to the actual application scene any linear driving mechanism in the prior art, so no further description is given.

[0078] In the present embodiment, the reversing mechanism 6 includes a rotating member 61 and a material frame 62. The rotating member 61 includes a turntable rotating around the horizontal direction. The material frame 62 is arranged on the turntable, and the material frame 62 is used to load and position a plurality of materials 13, so as to realize angle adjustment by the turntable of the rotating member 61 driving the materials 13 in the material frame 62, which can meet the needs of the material 13 direction of the processing equipment. It should be noted that the rotating member 61 can adopt any rotating driving mechanism in the prior art, such as a rotating motor, a rotating pneumatic cylinder, etc., and the present embodiment does not make specific requirements and limitations on this.

[0079] Among them, the material frame 62 includes a containing cavity matched with the inner cavity of the material box 12, and the containing cavity is open on one side and the upper side in the vertical direction. The reversing mechanism 6 further includes a fixed part 63 capable of vertical movement, which is configured to extend into the containing cavity from the upper side of the containing cavity and press down a plurality of materials 13 in the containing cavity.

[0080] It can be understood that the accommodating cavity of the material frame 62 is matched with the inner cavity of the material box 12, which ensures that the material 13 can be quickly aligned and accurately positioned when being transferred to the material frame 62, avoiding subsequent process jam caused by position deviation. It can also be understood that the vertical side and the upper side of the material frame 62 are open, which not only facilitates the loading of the material 13, but also provides operation space for the downward movement of the fixing part 63. More importantly, the fixing part 63 extends into the accommodating cavity from the upper side and presses the material 13 downward, which can stably fix the material 13 in the accommodating cavity, especially suitable for thin and fragile materials 13 such as cigarette boxes, preventing displacement, deformation or scattering of the materials 13 due to centrifugal force or vibration during rotation change, significantly improving the stability of the materials 13 during the change stage.

[0081] In order to further improve the loading efficiency, the conveying mechanism 5 includes a conveying frame 51 capable of moving along a predetermined path, the separating mechanism 4, the reversing mechanism 6 and the first loading channel are arranged along the predetermined path, and the conveying frame 51 is used to carry the materials 13 separated by the separating mechanism 4. The conveying mechanism 5 further includes a first pushing assembly, a second pushing assembly and a third pushing assembly, the first pushing assembly is used to push the materials 13 from the separating mechanism 4 to the conveying frame 51, the second pushing assembly is used to push the materials 13 from the conveying frame 51 to the reversing mechanism 6, and the second pushing assembly is also used to convey the materials 13 from the reversing mechanism 6 to the second loading channel, and the third pushing assembly is used to push the materials 13 from the conveying frame 51 to the first loading channel.

[0082] In this way, the conveying frame 51 moves along the arrangement path of the separating mechanism 4, the reversing mechanism 6 and the first loading channel, realizing the linearization and precision transmission of the materials 13 between processes, so as to avoid the detour transportation of the materials 13 and shorten the circulation time. For example, the conveying frame 51 can quickly transfer the separated materials 13 to the reversing mechanism 6 or the first loading channel, avoiding the low efficiency problem of traditional manual transportation or complex mechanical arm path planning, and improving the overall production efficiency.

[0083] It is worth noting that the first pushing assembly, the second pushing assembly and the third pushing assembly can adopt the same structure. Taking the first pushing assembly as an example, the first pushing assembly includes a pushing plate vertically abutting one side of the materials 13 and a driving part driving the pushing plate to move, and the driving part can adopt any driving structure in the prior art, such as a linear module.

[0084] Generally, the carton 12 is usually made of hard paperboard folding, and if it is recycled, it can significantly reduce the consumption of raw materials and reduce procurement costs. For example, the flattened carton 12 can directly enter the reprocessing process or be recycled as waste paper, avoiding the waste of resources caused by one-time disposal. To solve this problem, in the embodiment, the tobacco packaging machine feeding device further comprises a recycling mechanism 7, which is configured to receive and flatten the carton 12 separated by the separating mechanism 4. In addition, after being flattened, the separated carton 12 is greatly reduced in size, facilitating centralized storage and transportation.

[0085] Further, the recycling mechanism 7 comprises a flattening assembly 71, a recycling channel 72, and a recycling frame 73. The flattening assembly 71 is arranged on the second frame body 3 and is used to flatten the carton 12. The recycling channel 72 is located below the separating mechanism 4 to receive the carton 12 separated by the separating mechanism 4 and transport the carton 12 downward. The recycling frame 73 is movably arranged and has a receiving position and an output position. When the recycling frame 73 is located at the receiving position, it can receive the carton 12 output by the recycling channel 72, and when the recycling frame 73 is located at the output position, it can output the carton 12 to the flattening assembly 71.

[0086] In this way, the recycling channel 72 directly receives the carton 12 separated and dropped by the separating mechanism 4, realizing the automatic circulation of the carton 12 from separation to recycling without manual intervention, reducing the time and labor cost of carton 12 transportation. In addition, the recycling channel 72 is arranged below the separating mechanism 4, making full use of the vertical space of the second frame body 3 and avoiding the occupation of horizontal space. In addition, by switching between the receiving position and the output position of the recycling frame 73, the automatic circulation of the carton 12 from collection to transportation is realized, which can further reduce the time and labor cost of carton 12 transportation.

[0087] Specifically, the flattening assembly 71 comprises a grabbing piece 711 and a plurality of flattening pieces 712. The grabbing piece 711 is movably arranged and is configured to grab and fix the carton 12 output by the recycling frame 73. The plurality of flattening pieces 712 are distributed around the grabbing piece 711, and the number of flattening pieces 712 corresponds to the number of side edges of the carton 12. The plurality of flattening pieces 712 can be gathered or dispersed outward, and when the plurality of flattening pieces 712 are dispersed outward, they can expand the plurality of side edges of the carton 12 to flatten the carton 12.

[0088] In this way, the plurality of flattening members 712 are arranged according to the number of side edges of the box 12, and can simultaneously apply an opening force to the box 12 from multiple directions. For example, if the box 12 is a cuboid, four flattening members 712 can correspond to the four side edges respectively, and by synchronously dispersing outward, the folded side edges are uniformly opened, so that the box 12 is balanced in each direction. Thus, the deformation or damage of the box 12 caused by single-point force can be avoided, and it is especially suitable for paper or thin plastic boxes 12 with brittle texture. In addition, the flattening members 712 can be gathered or dispersed outward, which can adapt to boxes 12 of different sizes. In the production scene of a tobacco factory with multiple varieties, different specifications of cigarette boxes (such as hard boxes, soft boxes, and packaging with different length-width ratios) can be effectively flattened by adjusting the spacing of the flattening members 712.

[0089] It should be noted that the gripping member 711 can select a driving component according to the actual arrangement position, and the driving component is exemplarily composed of a plurality of linear modules. It is worth noting that if the box 12 needs to be turned, a transfer mechanism with a rotating function also needs to be used. It should also be noted that the gripping member 711 is preferably a vacuum suction structure in the prior art.

[0090] Obviously, the above embodiments of the present application are only examples for clear illustration of the present application, and are not a limitation on the embodiments of the present application.
