Abstract
Description
Technical Field
[0001] This utility model relates to a turning device, and more particularly to an automatic turning device for finished cigarette boxes. Background Technology
[0002] Nowadays, cigarette factories have increasingly higher requirements for product quality. Before the finished cigarette cartons sealed by the sealing machine flow into the finished product warehouse through the cigarette carton conveyor channel, the missing cigarette packs in the finished cigarette cartons need to be checked to ensure that the cigarette packs in the finished cigarette cartons are arranged normally and there are no missing packs. This is to avoid the occurrence of missing packs in the finished cigarette cartons on the market, so as not to affect the brand image established by the cigarette manufacturers in the market.
[0003] The existing technology uses the AV89751Z millimeter-wave box defect detection system from China Electronics Technology Group Corporation (CETC) to detect defects in finished cigarette boxes. This detection device checks the defect status of each finished cigarette box that passes through it, ensuring that the quality of finished cigarette boxes entering the finished cigarette box warehouse meets the production process requirements.
[0004] However, in actual production, the finished cigarette boxes sealed by the sealing machine are conveyed longitudinally into the cigarette box conveying channel. But the AV89751Z millimeter wave box defect detection system requires the finished cigarette boxes to be conveyed laterally for detection. This requires the finished cigarette boxes in the cigarette box conveying channel to be reversed before entering the AV89751Z millimeter wave box defect detection system, changing the conveying from longitudinal to lateral. Only in this way can the finished cigarette boxes be effectively detected by the AV89751Z millimeter wave box defect detection system. Currently, the reversing of the cigarette boxes needs to be done manually, which consumes a lot of manpower and is labor-intensive. Utility Model Content

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0017] Embodiments of this utility model: such as Figure 1 and Figure 2 As shown, an automatic orientation device for finished cigarette boxes includes a cigarette box conveying bracket 1. One end of the cigarette box conveying bracket 1 is connected to a cigarette box conveying channel 2 on a sealing machine. A photoelectric switch 3 is fixed on one side of the cigarette box conveying channel 2. A cigarette box transmission component and an elastic blocking device are installed on the cigarette box conveying bracket 1. Both the photoelectric switch 3 and the cigarette box transmission component are electrically connected to a PLC programmable controller.
[0018] The carton sealing machine is existing equipment used to pack finished cigarette cartons. The finished cigarette cartons are conveyed out of the sealing machine through cigarette carton conveyor channel 2. As the finished cigarette cartons leave conveyor channel 2, they pass through photoelectric switch 3 and then move to cigarette carton conveyor support 1. When the finished cigarette cartons pass through photoelectric switch 3, photoelectric switch 3 is blocked, sending a signal to the PLC programmable controller. After receiving the signal from photoelectric switch 3, the PLC controls the cigarette carton conveying component to operate. The conveying component moves the finished cigarette cartons. During this movement, one corner of the finished cigarette carton abuts against an elastic blocking device, causing the finished cigarette carton to rotate 90°, automatically changing from longitudinal conveying to transverse conveying. In this way, when the finished cigarette cartons pass through the AV89751Z millimeter-wave box defect detection system (not shown in the figure), it can accurately detect whether there are missing strips. This process requires no manual operation; the equipment operates automatically, which not only improves work efficiency but also saves labor costs.
[0019] In one specific embodiment, the cigarette box conveying support 1 is a rectangular frame welded together from a first side plate 11, a second side plate 12, a first end plate 13, and a second end plate 14. A support leg is fixed to each end of the bottom surface of the first side plate 11 and the second side plate 12. The cigarette box conveying assembly includes electric rollers 4 and non-powered rollers 5. Two electric rollers 4 and several non-powered rollers 5 are rotatably installed inside the cigarette box conveying support 1. The two electric rollers 4 are arranged close to the first end plate 13 and the second end plate 14. The drivers 6 of the two electric rollers 4 are fixed to the outer wall of the first side plate 11, and both drivers 6 are electrically connected to a PLC programmable controller. The PLC programmable controller is a commercially available product and can be purchased. The PLC programmable controller is not shown in the figure. In this embodiment, the preferred PLC programmable controller model is Siemens S7-300.
[0020] Both the electric roller 4 and the non-powered roller 5 are commercially available products and can be purchased directly. The electric roller 4 is used to move the finished tobacco box when it rotates, while the non-powered roller 5 allows the finished tobacco box to be moved easily.
[0021] In this embodiment, the electric roller 4 and the non-powered roller 5 have an angle of 15°-20° with the first side plate 11, preferably 15°. The second side plate 12 is parallel to the first side plate 11. This structural design ensures that the finished cigarette box moves towards the second side plate 12 when it moves on the electric roller 4 and the non-powered roller 5, thus guaranteeing that one corner of the finished cigarette box abuts against the elastic blocking device.
[0022] Furthermore, the elastic blocking device includes an elastic blocking roller 7, a blocking roller mounting bracket 8, and a mounting base 9. The mounting base 9 is fixed on the second side plate 12. The mounting base 9 has three mounting holes, which are evenly distributed along the vertical direction. The elastic blocking roller 7 is rotatably mounted on the blocking roller mounting bracket 8. Three bolts 10 are fixed on the blocking roller mounting bracket 8. The three bolts 10 pass through the three mounting holes and are threaded to nuts respectively. Each of the three bolts 10 is fitted with a spring, which is not shown in the figure.
[0023] The elastic blocking roller 7 is arranged vertically. When one corner of the finished cigarette box comes into contact with the elastic blocking roller 7, the elastic blocking roller 7 moves towards the mounting base 9. At the same time, the blocking roller mounting bracket 8 compresses the spring. The spring is used to offset the impact force of the finished cigarette box on the elastic blocking roller 7, thereby protecting the finished cigarette box and preventing the finished cigarette box from directly colliding with the elastic blocking roller 7 and causing damage to the corner.
[0024] The elastic blocking device is located on the middle of the second side plate 12, biased towards the second end plate 14. The purpose of this is to provide a sufficient distance for the finished cigarette box to move so that it can accurately abut against the elastic blocking roller 7.
[0025] Furthermore, a first smoke box baffle 15 and a second smoke box baffle 16 are also fixedly provided on the second side plate 12. The two ends of the first smoke box baffle 15 are fixedly connected to the second side plate 12 through the first connecting rod 18. One end of the first smoke box baffle 15 is close to the elastic blocking roller 7, and the other end of the first smoke box baffle 15 extends to the top of the first end plate 13. The distance between the first smoke box baffle 15 and the second side plate 12 gradually increases from the end close to the elastic blocking roller 7 to the other end.
[0026] The two ends of the second smoke box baffle 16 are fixedly connected to the second side plate 12 through the second connecting rod 17, and the second smoke box baffle 16 and the second side plate 12 are arranged in parallel.
[0027] The first cigarette box baffle 15 is arranged at an angle. When the finished cigarette box approaches the second side plate 12, the first cigarette box baffle 15 guides the corners to accurately abut against the elastic blocking roller 7. The second cigarette box baffle 16 is used to limit the rotation angle of the finished cigarette box. When the finished cigarette box contacts the second cigarette box baffle 16, it cannot continue to rotate and instead enters the next process in a straight line under the guidance of the second cigarette box baffle 16.
[0028] To save power, in a preferred embodiment, a second photoelectric switch 19 is provided at the end of the first side plate 11 away from the sealing machine. The second photoelectric switch 19 is electrically connected to the PLC programmable controller. When the finished cigarette box passes the second photoelectric switch 19, the second photoelectric switch 19 sends a signal to the PLC programmable controller. After receiving the signal, the PLC programmable controller controls the two electric rollers 4 to stop working through the two drivers 6 after a preset delay.
[0029] The working principle of this utility model is as follows: After the finished cigarette boxes are packaged in the sealing machine, they are sent out of the sealing machine through the cigarette box conveying channel 2. When the finished cigarette boxes leave the cigarette box conveying channel 2, they will pass through the photoelectric switch 3 and then move to the cigarette box conveying support 1.
[0030] When the finished cigarette box passes the photoelectric switch 3, the photoelectric switch 3 is blocked. The photoelectric switch 3 sends a signal to the PLC programmable controller. After receiving the signal from the photoelectric switch 3, the PLC programmable controller controls the two drivers 6 to work. The two electric rollers 4 start to rotate. The electric rollers 4 drive the finished cigarette box to move. Since the electric rollers 4 and the unpowered rollers 5 are arranged at an angle, the finished cigarette box will move obliquely towards the second side plate 12. The side of the finished cigarette box will contact the first cigarette box baffle 15. Then, under the guidance of the first cigarette box baffle 15, one corner of the finished cigarette box abuts against the elastic blocking roller 7. The elastic blocking roller 7 moves towards the mounting base 9. At the same time, the blocking roller mounting bracket 8 compresses the spring. The spring is used to offset the impact force of the finished cigarette box on the elastic blocking roller 7.
[0031] Because the corners of the finished cigarette box are blocked by the elastic blocking roller 7, the finished cigarette box can only start rotating around the elastic blocking roller 7. When the finished cigarette box comes into contact with the second cigarette box baffle 16, the finished cigarette box rotates 90°, automatically changing from longitudinal conveying to transverse conveying. Then it continues to move to the next process along the second cigarette box baffle 16. When the finished cigarette box passes the second photoelectric switch 19, the second photoelectric switch 19 sends a signal to the PLC programmable controller. After receiving the signal, the PLC programmable controller delays for a preset time and then controls the two electric rollers 4 to stop working through the two drivers 6.
[0032] When the finished cigarette box passes through the AV89751Z millimeter wave box defect detection system, it can accurately detect whether there are missing strips.
