Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to a cigarette rotating device. Background Art

[0002] During the cigarette rolling process, the tobacco bundle passes through a device such as a tobacco gun, gluing device, soldering iron, cloth belt wheel, and strip maker, where it is papered, glued, sealed, and ironed. This creates a stable, continuous tobacco strip with dimensions and density that meet process requirements. This is then fed into the cigarette cutting system, where it is formed into double-length cigarettes that meet process requirements. A spider arm then accurately feeds these double-length cigarettes into the cigarette feeding drum groove of the cigarette receiving machine. During the gluing process, various factors, such as glue quality, glue quantity, paper roll height, sealing position, and ironing degree, often cause the robotic arm's gripper to become contaminated with excess glue from the cigarettes. This impairs the gripper's gripping ability and causes cigarettes to be thrown off. In severe cases, the entire production line must be shut down, impacting production progress. Furthermore, over time, glue accumulates on the robotic arm's gripper, shortening its lifespan and requiring regular, deep cleaning, which is time-consuming, labor-intensive, and expensive.

[0027] This embodiment provides a cigarette rotating device. Figure 1As shown, the cigarette rotation device includes a base 1 and a gas delivery device 2. The base 1 is provided with a passage for placing cigarettes. An air inlet 101 is defined on the outside of the base 1, and an air delivery cavity 102 is defined within the base 1. An air outlet 103 is defined on the inner wall of the passage. The air inlet 101 is connected to the air delivery cavity 102, which in turn is connected to the air outlet 103. The gas delivery device 2 is connected to the air inlet 101 and is used to deliver gas to the air inlet 101. The gas is blown out sequentially through the air inlet 101, the air delivery cavity 102, and the air outlet 103, thereby driving the cigarette in the passage to rotate along its own axis.

[0028] In this embodiment, during the transportation process of cigarettes, they enter the channel of the seat body 1, and the gas delivery device 2 delivers gas to the air inlet 101. The gas enters the gas delivery cavity 102 through the air inlet 101 and is then blown into the inside of the channel through the gas delivery hole. When a cigarette passes through the channel, the blown gas can drive the cigarette in the channel to rotate along its own direction by a certain angle. When the cigarette moves out of the channel and is ready to be clamped by the gripper of the robot arm, the gluing part of the cigarette can be staggered with the gripping position of the gripper of the robot arm due to the rotation, thereby avoiding glue accumulation in the gripper of the robot arm, ensuring stable and reliable cigarette gripping, preventing cigarette throwing, ensuring smooth and reliable operation of the entire production line, and reducing the frequent glue cleaning and maintenance work caused by glue accumulation in the gripper of the robot arm.

[0029] Specifically, during the design process of the position of the air outlet 103, after mechanical angle analysis, attempts were made to drill holes at 15°, 30°, 45°, and 60° angles perpendicular to the plane of the base body 1 through the center of the channel for simulation experiments. Finally, under the condition of a constant positive pressure blowing volume and the same diameter of the air outlet 103, compared with the 15° and 30° positions, the 45° position can completely rotate the glue joint of the cigarette to a point where it does not contact the spider hand suction claw, and compared with the 60° position, the 45° position will not cause any damage to the cigarette. Therefore, the position of the air outlet 103 is determined to be at a 45° position relative to the center line of the channel.

[0030] In this embodiment, the base body 1 includes two interlocking seat sections 11. Each seat section 11 defines a receiving slot 111. The two seat sections 11 interlock, forming a passageway. At least one seat section 11 defines an air inlet 101, an air delivery cavity 102, and an air outlet 103. Specifically, configuring the base body 1 as two separate seat sections 11 provides a simple structure, eases fabrication, and facilitates regular inspection and cleaning of the passageway within the base body 1.

[0031] As an optional embodiment, one of the two seat parts 11 is provided with a through-hole 104, and the other is provided with a corresponding threaded hole 105, and a screw is passed through the through-hole 104 and threadedly connected to the threaded hole 105. Specifically, after the screw passes through the through-hole 104, it is threadedly fastened with the threaded hole 105, so that the two seat parts 11 can be reliably fixed, with a simple structure and convenient assembly and disassembly. Optionally, a plurality of through-holes 104 and threaded holes 105 are provided in a one-to-one correspondence. In this embodiment, the seat body 1 is configured as a rectangular parallelepiped, that is, both seat parts 11 are configured as rectangular parallelepipeds. One of the two seat parts 11 is provided with four through-holes 104, and the other is provided with four threaded holes 105. The four through-holes 104 and the four threaded holes 105 are correspondingly distributed at the four corners of the rectangular side of the seat part 11.

[0032] In some other optional embodiments, the two seat sections 11 may be fixedly connected without holes and screws. Instead, the two end surfaces of the two seat sections 11 that abut against each other may each be provided with a magnetic attraction portion, with the two magnetic attraction portions having opposite magnetic properties. The two seat sections 11 can be attracted by the two magnetic attraction portions, thereby achieving a fixed connection between the two seat sections 11.

[0033] Optionally, the number of channels on the seat body 1 is set at intervals. Specifically, the number of the receiving grooves 111 on each seat portion 11 is set to two, that is, the seat body 1 is provided with two channels.

[0034] In this embodiment, the cross-sectional shape of the receiving groove 111 is set to be semicircular, and the two receiving grooves 111 are combined to form a circular channel. Such a configuration can adapt to the shape of a circular cigarette.

[0035] Specifically, the cross-sectional diameter of the circular channel is larger than the diameter of the cigarette. This configuration ensures that the cigarette slides and rotates effectively within the channel. For example, the cross-sectional diameter of the circular channel is 1-2 mm larger than the diameter of the cigarette, preventing the cigarette from shaking due to excessive speed, which could affect normal operation.

[0036] Optionally, the inner wall of the receiving groove 111 is provided with a plurality of air outlet holes 103, which are evenly spaced along the length of the receiving groove 111. Specifically, each receiving groove 111 is provided with air outlet holes 103 on both sides thereof, and each receiving groove 111 is provided with three air outlet holes 103 spaced along its length. This arrangement ensures uniform blowing of air into the channel, ensures uniform force on the cigarette, and improves the reliability of the cigarette rotation.

[0037] Optionally, the diameter of the air outlet 103 is designed to be 1 / 5 of the diameter of a slim cigarette according to the diameter requirements of the slim cigarette and the actual situation. Optionally, the diameter of the air outlet 103 is 1 mm to 2 mm.

[0038] Optionally, the cross-sectional shape of the gas delivery cavity 102 is set to be an arc shape. This configuration, on the one hand, adapts to the cross-sectional shape of the semicircular receiving groove 111, and on the other hand, can minimize the power consumption of the gas delivery equipment 2 while ensuring that the gas is blown out stably from the gas outlet 103.

[0039] Optionally, the outer diameter of the gas delivery cavity 102 is set to be at least 3 mm larger than the channel diameter, and at most 6 mm larger.

[0040] In this embodiment, the air delivery device 2 includes a fan 21, which is connected to the air inlet 101 through an air delivery pipe 22. Specifically, the fan 21 generates a certain intensity of positive pressure blowing air, which is passed into the air inlet 101 through the air delivery pipe 22.

[0041] In this embodiment, an on-off valve (not shown) is installed on the gas pipe 22 to open and close the gas pipe 22. When the gas delivery device 2 starts to supply air, the on-off valve is in an open state; when the gas delivery device 2 is not working, the on-off valve is in a closed state.

[0042] Optionally, the switch valve is configured as a solenoid valve.

[0043] Optionally, the switch valve can be controlled by a control module such as a PLC to achieve automatic opening and closing operations.

[0044] Optionally, the gas pipe 22 is made of aluminum alloy.

[0045] In summary, the cigarette rotation device provided in this embodiment has a simple structure and can drive the cigarette to rotate along its own axis, so that the clamping claws of the robotic arm are staggered with the gluing part of the cigarette, avoiding glue accumulation in the clamping claws of the robotic arm and ensuring stable and reliable cigarette grasping.
