Description

Technical Field

[0001] The invention relates to the technical field of cigarette overturning conveying equipment, and in particular to a cigarette overturning conveying mechanism and method. Background Art

[0002] Cigarettes, as a consumer product, have a large proportion in the consumer market. For example, a side-opening gold-medium brand cigarette is positioned as a high-end cigarette product and is widely popular in the market. Side-opening gold-medium brand cigarettes are produced and packaged by YB417C side-opening packaging prototype machine.

[0003] In the existing production process, since the YB417C side-opening packaging prototype cannot be operated online with the cigarette making equipment in the previous process, it is necessary to use the tilting conveyor system to first transport the cigarettes to the cigarette warehouse of the YB417C side-opening packaging prototype, and then divert them and output them to the subsequent packaging process.

[0004] The existing tray turning and conveying system uses a traditional tray turning machine with a long cigarette conveying channel to convey cigarettes to the cigarette storage of the YB417C side-opening packaging prototype. The traditional tray turning machine is large, and when combined with the long cigarette conveying channel, it occupies too much space, which limits the layout of the entire unit equipment and hinders the improvement of the plant area utilization rate; more seriously, when the cigarettes pass through the long cigarette conveying channel, the probability of damage to the appearance of the cigarettes is greatly increased, which is not conducive to the improvement of cigarette quality.

[0005] In addition, the YB417C side-opening packaging prototype is equipped with a spring unloading support device, with two diamond-shaped guide blocks symmetrically distributed on both sides. The purpose is to increase the support for the cigarettes, absorb the instantaneous downward pressure of the cigarettes, and interrupt the lateral support force between the cigarettes, so as to guide the downward flow of cigarettes. However, in actual application, the unloading and pressure relief effect of the spring unloading support device arranged in the center alone is not enough, and the effect of the diamond-shaped guide blocks on both sides is not obvious, and it is impossible to ensure that the top layer of cigarettes in the cigarette warehouse is level. The uneven top layer of cigarettes will cause some areas of cigarettes to drop too much. When the cigarettes are turned over and transported into the cigarette warehouse, the falling impact of the cigarettes is too large, which will cause the cigarettes in contact above and below to be squeezed and deformed.

At this time, the cigarette docking plate 2 receives the whole tray of cigarettes 9, and the whole tray of cigarettes 9 follows the docking plate to move downward into the upper cigarette warehouse 1, and the whole tray of cigarettes 9 blocks the horizontal plane of the high-position photoelectric detector.

[0064] A2.2: When the cigarettes 9 in the upper cigarette warehouse 1 fall below the horizontal line of the low-level photoelectric detector, the low-level photoelectric detector is turned on, and the cigarette docking drawer 2 continues to move downward to the horizontal line of the low-level photoelectric detector. Then, the upper cigarette warehouse clapper 101 is reset under the action of the upper cigarette warehouse clapper drive assembly 102 to block the cigarettes 9 on the cigarette docking drawer 2. Then, the cigarette docking drawer 2 moves forward, the cigarette docking drawer 2 is drawn out of the upper cigarette warehouse 1, and the cigarettes 9 fall into the upper cigarette warehouse 1.

[0065] A3: The lower cigarette bin diversion component 5 diverts the cigarettes 9, and the cigarettes 9 are transported outward by docking with the cigarette bin guide rail 6;

[0066] A3.1: After the cigarettes 9 in step A2.2 fall into the upper cigarette bin 1, the cigarettes 9 flow into the lower cigarette bin 4, and the gravity of the cigarettes 9 is shared by several lower cigarette bin diversion components 5. When the cigarettes 9 abut against the top roller 501, the top roller 501 transports the cigarettes 9 to the two sides of the top roller 501, and the cigarettes 9 are diverted to the two oblique sides of the triangular diversion rack 502, and enter the side of the diversion rotating tripod 504 under the action of the floating side plate 505 and the fixed side plate 506. Because the diversion rotating tripod 504 is hinged to the fixed side plate 506, when the number of cigarettes 9 on one side of the left or right side is large and the flow rate is large, the diversion rotating tripod 504 will deflect to the side with a small number and a small flow rate, ensuring that the top surface of the cigarettes 9 is as horizontal as possible, and there will be no problems of protrusions or depressions in some places.

[0067] A3.2: The cigarettes 9 diverted by the diverting rotating tripod 504 are transported to the outside of the lower cigarette bin 4 through the docking cigarette bin guide rail 6 below the lower cigarette bin 4 for subsequent production process operations.

[0068] Preferably, in step A3.1, the top surface of the cigarette 9 is ensured to be as horizontal as possible without protrusions or depressions. The purpose is that when the cigarette is pulled out of the extraction plate 2, the entire tray of cigarettes 9 falls as a whole without deforming the cigarettes 9 in the depressions, thereby reducing the height difference.

[0069] Preferably, in step A3.1, when the entire tray of cigarettes 9 in step A2.2 falls into the upper cigarette bin 1, the entire tray of cigarettes 9 will experience a downward gravity, and the spring 508 in the lower cigarette bin diversion assembly 5 is used to offset the gravity of the entire tray of cigarettes 9 to prevent the cigarettes 9 on the top layer of the lower cigarette bin 4 from being squeezed and deformed.

[0070] Furthermore, in this embodiment, the design calculation and analysis of the spring 508 are also involved, as follows:

[0071] 1. Design requirements for spring 508; as shown in the following table:

[0072]

[0073] Theoretically, the cigarette speed is 16,000 cigarettes / min, and the cigarette tray has 4,000 cigarettes. The transportation speed of the whole tray of cigarettes is: 16,000÷4,000=4 (times / min);

[0074] N 理论 =3 years×250 days×8h×60min×4=1440000<N(number of load actions);

[0075] That is, the life of one spring 508 under normal use is 3 years.

[0076] 2. The material selection of spring 508 is as follows:

[0077] Material grade 60Si2MnA, check the material properties according to the manual.

[0078] 3. The end form design of spring 508 is as shown in the following table:

[0079]

[0080]

[0081] Where NⅢ represents the center arm torsion spring; the wire diameter d≥0.5mm, suitable for ordinary cold-rolled cylindrical torsion spring;

[0082] The end structure of the spring 508 is that both ends are coiled and tightened and ground flat.

[0083] 4. The basic parameters of spring 508 are as follows:

[0084]

[0085] 5. The remaining dimensional parameters of spring 508 are as follows:

[0086]

[0087] The cigarette turning tray conveying mechanism and method involved in the present invention solve the problems of the prior art that the turning tray machine equipment is large, the cigarette conveying channel is too long, the floor space is large, and the utilization rate of the factory area is low. After adopting the present application, the floor space of the equipment is reduced by 60%, and at the same time, the problem of the appearance of the cigarettes 9 being damaged during the process of the cigarette conveying channel is avoided. Three lower cigarette warehouse diversion components 5 are provided, and the lower cigarette warehouse diversion components 5 are used to interrupt the lateral support between the cigarettes 9, so that the cigarettes 9 can flow freely like a fluid, ensuring that the top layer of the lower cigarette warehouse 4 is level, and avoiding the problem of the cigarettes 9 being deformed due to the large drop of the cigarette tray cigarettes 9.

[0088] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
