Description

Technical Field

[0001] The utility model relates to a high-speed cigarette small packet rejecting device. Background Art

[0002] Usually, the rated production efficiency of the GDX1 / 2 packaging machine is 400 packs / minute, that is, the production time of a pack of cigarettes takes 150ms. After the production of the small cigarette pack (cigarette pack) is completed, it is transmitted to the next packaging process through the cigarette pack conveying channel. Therefore, the theoretical running speed of the cigarette pack on the conveying channel is 150ms. However, in order to improve production efficiency, the belt speed on the cigarette pack conveying channel is accelerated, which is conducive to the timely transportation of the cigarette pack to the next packaging station. Therefore, in actual testing, it takes about 85ms for the cigarette pack to scan a pack of cigarettes on the conveying channel. At this time, after the bad cigarettes are detected, the defective cigarette packs are promptly removed from the conveying channel through the removal device.

[0003] The traditional reject box is a whole reject box across the cigarette pack conveying channel, and the width of the whole reject box (including the width of the guide strip) is about 315.5mm. This reject box is suitable for packaging machines with a production efficiency of 400 packs / minute or less.

[0004] Nowadays, with the rapid development of technology, more and more high-speed machines are gradually entering the tobacco industry. The rated production speed of such packaging machines has reached 600-800 packs / minute. Therefore, the belt speed of the cigarette pack conveying channel matched with such packaging machines is faster. For example, the GDS6S model has a rated production efficiency of 600 packs / minute, that is, 100ms per pack of cigarettes, which is 1.5 times faster than the medium-speed car. In actual testing of cigarette packs on the conveying channel, it takes about 24ms to scan a pack of cigarettes, which is more than 3 times faster than the medium-speed car.

[0005] When continuous defective cigarette packs are rejected, for traditional medium-speed vehicles, on the conveying channel, the inertia of the cigarette packs in the direction of travel is small. After the defective cigarette packs are blown out, they will fall directly into the cigarette receiving box by their own gravity and will not hit the side panels of the traditional rejection box; for high-speed vehicles, the cigarette packs run fast on the conveying channel and have great inertia in the direction of travel. When a large number of continuous defective cigarette packs are produced, the inertia generated by the high-speed running speed of the rejected cigarette packs is much greater than the downward flight speed generated by their own gravity. Therefore, the cigarette packs themselves will continue to fly out in the direction of the cigarette packs, resulting in the front cigarette packs not having time to fall into the cigarette receiving box, and the rear cigarette packs are all piled up, and because the front cigarette packs hit the side panels first, the inertial speed of the cigarette packs on the horizontal X axis slows down, but the inertial speed of the rear rejected cigarette packs on the horizontal X axis remains unchanged, resulting in a backlog of cigarette packs that affects the travel of the rear good cigarettes, and even directly pushes the bad cigarettes to the rejection port to get stuck. This is the cigarette jam phenomenon that occurs at the exit of the rejection box. Therefore, for high-speed vehicles, on the one hand, higher requirements are placed on the detection processing time, and on the other hand, higher requirements are placed on the structure of the reject box. The traditional reject box will no longer be suitable for high-speed vehicles and needs to be improved. Summary of the invention

[0006] In order to solve the problem that cigarettes may get stuck at the exit of the conventional rejection box when used in high-speed vehicles, the utility model provides a high-speed cigarette packet rejection device.

[0007] The high-speed cigarette packet rejection device of the utility model comprises a rejection air nozzle, a cigarette packet conveying channel and a cigarette receiving box, wherein the rejection air nozzle is located on one side of the cigarette packet conveying channel, and the cigarette receiving box is located on the other side of the cigarette packet conveying channel, and the cigarette receiving box is an independent box body with a top opening, and the top opening of the cigarette receiving box is rectangular, and the long side is parallel to the cigarette packet conveying channel, and the length of the long side is 550-650mm. By setting the cigarette receiving box as an independent box body, it is more convenient to manufacture compared with the traditional rejection box in which the cigarette receiving box and other components of the rejection box are an integrated structure; by setting the length of the long side of the upper opening of the cigarette receiving box to 550-650mm, compared with the previous upper opening length of 315.5mm, the cigarette packet has a longer flight path, thereby avoiding cigarette jams.

[0008] The cigarette receiving box is funnel-shaped, so that the cigarette packs entering the cigarette receiving box can be smoothly gathered at the bottom for easy collection.

[0009] A cigarette pack outlet is provided on one side wall of the cigarette receiving box and a sliding door for opening and closing the cigarette pack outlet is installed, so that the collected and discarded cigarettes can be conveniently taken out.

[0010] A baffle is provided on the top opening of the cigarette receiving box, so that the high-speed cigarette packs that are rejected can be prevented from flying out of the cigarette receiving box, which is conducive to collection.

[0011] Beneficial effects: The utility model separates the cigarette receiving box integrally formed on the traditional reject box, so that the manufacture of the cigarette receiving box is more convenient, and the long side length of the top opening of the cigarette receiving box is lengthened to 550-650mm, so as to avoid cigarette jamming in the cigarette receiving box; by setting the cigarette receiving box in a funnel shape, it is convenient for the rejected cigarette packs to be smoothly collected at the bottom; by providing a cigarette pack outlet and a sliding door on one side wall of the cigarette receiving box, it is convenient to take out cigarettes; by arranging a baffle on the top opening of the cigarette receiving box, it is prevented that the rejected cigarette packs are moving at high speed and fly out of the cigarette receiving box, which is conducive to collection.

[0014] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0015] like Figure 1 As shown, the utility model is a high-speed cigarette packet rejection device 1, comprising a rejection air nozzle 2, a cigarette packet conveying channel 3 and a cigarette receiving box 4, wherein the rejection air nozzle 2 is located on one side of the cigarette packet conveying channel 3, and the cigarette receiving box 4 is located on the other side of the cigarette packet conveying channel 3, and the cigarette receiving box 4 is an independent box body with a top opening, and the top opening of the cigarette receiving box 4 is rectangular, and the long side is parallel to the cigarette packet conveying channel 3, and the length of the long side is 600mm; the width is the width of the traditional rejection box cigarette receiving box. A baffle 43 is arranged on the top opening of the cigarette receiving box 4.

[0016] The cigarette receiving box 4 is funnel-shaped, that is, a part of the inner wall is an inclined surface 41; a cigarette packet outlet is opened on one side wall of the cigarette receiving box 4 and a sliding door 42 for opening and closing the cigarette packet outlet is installed. The bottom of the cigarette receiving box 4 is fixed by a hinge.

[0017] In actual use, after the cigarette packets traveling at high speed along the cigarette packet conveying channel 3 are blown out of the cigarette packet conveying channel 3 by the rejection air nozzle 2, they fall while traveling at high speed, and fall on the inclined surface 41 in the cigarette receiving box 4, and then slide to the bottom of the cigarette receiving box 4. When the cigarette receiving box 4 is full, the sliding door 42 is opened to take out the cigarettes, and finally the sliding door 42 is closed. In addition, due to the provision of the baffle 43, it can be ensured that the rejected cigarette packets fall smoothly into the cigarette receiving box 4. The rejection device of the utility model can be adapted to both medium-speed vehicles and high-speed vehicles, and can solve the problem of cigarette jams caused by the cigarette packets themselves being unable to fall into the cigarette receiving box in time due to the high-speed travel of the cigarette packets themselves.
