Description

Technical Field

[0001] The utility model relates to a taking-out device, in particular to an automatic taking-out device for cigarette cartons of a packaging machine. Background Art

[0002] YB25 / YB45 soft and hard pack cigarette packaging unit is a high-speed cigarette packaging unit domestically produced by Shanghai Tobacco Machinery Factory using the technology introduced from Italian GD Company in the 1990s. The unit has a high degree of production automation, high packaging product quality, and stable operation. It is currently the main packaging model for major cigarette industrial enterprises across the country. In order to improve the packaging quality of the transparent paper for the outer packaging of large cigarette packs, many domestic manufacturers have added large strip transparent paper beautification and plastic surgery devices to address the wrinkles and uneven appearance of the strip transparent paper. However, in actual production, when the equipment encounters equipment failures, replacement of raw and auxiliary materials, etc. during operation, the equipment will be shut down for too long (more than 20 seconds). If the operator fails to remove the cigarette strips in the beautification device in time, the high temperature of the soldering iron of the beautification device will damage the product. The appearance and internal quality of the product will change dramatically, seriously affecting the quality of the product. This not only directly leads to the consumption of raw and auxiliary materials of the product, but if the operator is careless or other factors prevent the cigarette cartons from being removed in time, the damaged cigarette cartons will flow into the next process, which will increase the labor intensity of the workers and cause a waste of human resources. The flow into the market will further affect the reputation of the company's cigarette brand. Utility Model Content

[0018] The PLC programmable controller (not shown in the figure) is fixed at the bottom of the bottom plate 1. The PLC programmable controller is also electrically connected to the packaging machine. During installation, the original bottom plate 1 on the packaging machine needs to be removed and replaced with the bottom plate 1 of the utility model. The shape and size of the bottom plate 1 of the utility model are the same as those of the original bottom plate on the packaging machine. The push-pull device is used to push or pull the second cigarette conveyor belt device to clamp the cigarette 33 or release the cigarette 33. The cigarette detection device is used to detect whether there is a cigarette 33 above the lower soldering iron plate 6 after a preset time when the packaging machine is stopped. The first cigarette conveyor belt device and the second cigarette conveyor belt device are used to convey the cigarette 33 away to realize automatic cigarette removal.

[0019] In a specific embodiment, the first side baffle 2 and the second side baffle 3 have the same structure and are arranged opposite to each other. The first side baffle 2 and the second side baffle 3 are both located at the cigarette entrance end of the bottom plate 1, and the first side baffle 2 and the second side baffle 3 are fixedly connected to the bottom plate 1 through two angle plates 5 respectively.

[0020] Each angle plate 5 is provided with a long hole, and the position of the first side baffle 2 and the second side baffle 3 can be fine-tuned by adjusting the position of the angle plate 5 to change the distance between them, so that the first side baffle 2 and the second side baffle 3 can effectively limit the cigarette strip 33, so that the cigarette strip 33 can move along the preset path.

[0021] Further, the detection port 4 is located at a recessed position of the lower soldering iron plate 6, and the cigarette detection device includes an optical fiber detector 7 and a detection bracket 8. The optical fiber detector 7 is fixed in the detection port 4 on the bottom plate 1 through the detection bracket 8; the optical fiber detector 7 is a commercially available component and can be directly purchased and obtained.

[0027] Furthermore, a driving device is provided at the bottom of the base plate 1, and the driving device includes a servo motor 20, a main transmission gear 21 and a driven gear 22. The main transmission gear 21 is fixedly mounted on the output shaft of the servo motor 20, a rotating shaft 23 is fixedly provided on one side of the driven gear 22, and a spline sleeve 24 is fixedly provided on the other side of the driven gear 22. Two mounting brackets 25 are provided on the bottom surface of the base plate 1, the rotating shaft 23 is rotatably connected to one of the mounting brackets 25, and the spline sleeve 24 is rotatably connected to the other mounting bracket 25. The end of the rotating shaft 23 is connected to the rotating shaft of the first driving pulley 10 through the first transmission bevel gear set 26, a spline shaft 27 is inserted in the spline sleeve 24, and one end of the spline shaft 27 located outside the spline sleeve 24 is connected to the second driving pulley 14 through the second transmission bevel gear set 28, and the servo motor 20 is electrically connected to the PLC programmable controller.

[0028] The rotating shaft 23, the driven gear and the spline sleeve 24 are coaxial, and ball bearings are provided at the matching positions of the rotating shaft 23 and the spline sleeve 24 and the mounting bracket 25 to ensure the smooth rotation of the rotating shaft 23 and the spline sleeve 24. A spring (not shown in the figure) is provided in the spline sleeve 24, and the spring is used to ensure that the second transmission bevel gear set 28 is always in a meshing state. It should be noted that the driving device used in this embodiment is only a preferred solution. In addition, two servo motors can be provided to drive the first driving pulley 10 and the second driving pulley 14 respectively. Of course, other solutions that can drive the first driving pulley 10 and the second driving pulley 14 are also within the protection scope of the present utility model.

[0029] Furthermore, the tops of the base plate 9 and the sliding plate seat 31 are both equipped with belt support components, which include a brush plate 29 and a brush holder 30. Two brush holders 30 are installed on the brush plate 29, and the mounting holes of the brush holders 30 are also designed as waist-shaped holes. The position of the brush plate 29 can be adjusted by adjusting the position of the brush holders 30. The brush surface on the brush plate 29 contacts the first conveyor belt 13 and the second conveyor belt 17, and plays a supporting role for the first conveyor belt 13 and the second conveyor belt 17, so that they can effectively convey the cigarette strips 33 during operation, solving the problems of slipping and cigarette strip deflection.

[0030] The working principle of the utility model is as follows: when the equipment is operating normally, the packaging machine pushes the cigarette strips 33 forward through the cigarette pushing plate 32, and the sliding plate seat 31 moves backward under the drive of the first push-pull cylinder 18 and the second push-pull cylinder 19, so that the spacing of the cigarette strip channels is increased to facilitate the passage of the cigarette strips 33.

[0031] When the equipment is shut down for a set time, the PLC programmable controller controls the optical fiber detector 7 to work and detect whether there is a cigarette 33 on the lower soldering iron plate 6. If a cigarette 33 is detected, the PLC programmable controller controls the first push-pull cylinder 18 and the second push-pull cylinder 19 to extend. The first push-pull cylinder 18 and the second push-pull cylinder 19 push the sliding plate seat 31 to move toward the direction of the cigarette 33 and press the cigarette 33. When the sliding plate seat 31 moves to the preset position, the first conveyor belt 13 and the second conveyor belt 17 clamp the cigarette 33. At this time, the PLC programmable controller controls the servo motor 20 to work, and the main transmission gear on the servo motor 20 The wheel 21 drives the driven gear 22 to rotate, and the rotation of the driven gear 22 drives the rotating shaft 23, the spline sleeve 24 and the spline shaft 27 to rotate synchronously. Under the transmission of the first transmission bevel gear group 26 and the second transmission bevel gear group 28, the first active pulley 10 and the second active pulley 14 rotate, so that the first conveyor belt 13 and the second conveyor belt 17 move, and the cigarette strips 33 on the bottom plate 1 are conveyed out in sequence, realizing the automatic removal of the cigarette strips 33; when all the cigarette strips 33 are conveyed out of the cigarette conveying channel, the PLC programmable controller controls the servo motor 20 to stop working, and at the same time controls the first push-pull cylinder 18 and the second push-pull cylinder 19 to retract and reset.

[0032] If the equipment is shut down for a set time, when the first conveyor belt 13 and the second conveyor belt 17 are conveying cigarettes 33, the equipment starts to reset. At this time, the PLC programmable controller controls the first push-pull cylinder 18 and the second push-pull cylinder 19 to shrink and reset immediately, and controls the servo motor 20 to stop working.

[0033] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
