Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing equipment, in particular to a round rod-shaped product transfer device for tobacco production. Background Art

[0002] Currently, domestic cigarette manufacturers use imported cigarette making machines such as the PROTOS70, 90S, 100, 1-8, 2C, 2-2, M5, and M8, as well as domestic cigarette making machines such as the ZJ17, ZJ112, ZJ116, ZJ118, and ZJ119. During their production processes, finished cigarettes are cut and then transported via a spider-hand conveyor to the receiving drum of the downstream filter-tipped machine. These different models of cigarette making machines utilize different spider-hand conveyors due to their varying operating speeds and machine structures. However, their structures and transmission principles are the same, and their operation and maintenance methods are essentially the same.

[0003] The function of the spider-arm conveying device is: the wheel body of the spider-arm conveying device rotates clockwise, and the multiple conveying arms on the wheel body rotate counterclockwise, driving the suction claws along an elliptical trajectory to suck up one or two cigarettes from the single-row or double-row V-shaped guide rail, and convey them to the receiving drum of the loading machine to complete the conveying process.

[0004] These spider-arm transmission devices utilize a planetary gear transmission within their wheels. The main shaft is fixed to the support housing, with a central gear mounted at the front end. The rotating wheel is fitted with a transition gear, and the arm rotates through a gear sleeve. A fixed pinion shaft is mounted at the center of the arm's rotation, and multiple transmission arms are mounted outside the gear sleeve. A certain amount of lubricant is applied to the wheel interior for lubrication and heat dissipation.

[0005] The spider-arm conveyor rotates clockwise, with several conveyor arms mounted on the wheel, each equipped with a suction claw. The conveyor arm rotates counterclockwise about its own center of rotation, and the suction claw on the conveyor arm also rotates clockwise about its own center of rotation. The angular velocities of the spider-arm conveyor, conveyor arm, and suction claw relative to their own centers of rotation are equal, so the suction claw remains horizontal regardless of the position of the conveyor arm. When the conveyor arm reaches its lowest point, the suction claw grabs the cigarette from the smoke conveying guide rail. When the conveyor arm reaches its leftmost point, the cigarette held by the suction claw aligns perfectly with a groove on the receiving drum of the loader. The suction claw loses its suction force, drops the cigarette, and the cigarette is sucked onto the receiving drum. The negative pressure required by the suction claw is provided by the vortex suction fan. When the suction claw rotates to the action area of ​​the suction block, negative pressure suction is generated to ensure that the cigarette is tightly combined with the suction claw during the period from the time the cigarette suction claw sucks it to the time it is handed over to the receiving drum of the loading machine; when the suction claw rotates to the action area of ​​the blowing block, positive pressure blowing is generated, and the cigarette foam on the suction claw is blown away by compressed air, ensuring the smooth progress of cigarette conveying.

[0006] The traditional spider-hand conveyor lubrication system of the cigarette citrus maker uses oil bath lubrication, with a certain amount of lubricating oil contained in the inner cavity of the wheel body. During production, the temperature of the lubricating oil in the inner cavity of the wheel body will continue to rise, generating a large amount of lubricating oil vapor, which will leak from the oil cavity to the oil seal and then into the negative pressure channel. Lubricating oil leakage may also occur due to aging and wear of sealing components. The main problems caused by this are: first, the oil quality defects of the cigarettes; second, the oil and soot mixed together and were sucked into the negative pressure suction channel, causing blockage in the conveyor arm air duct, the inner cavity of the suction block, and even the fan, resulting in cigarette drop failure during the cigarette conveying process, causing abnormal equipment operation and reduced operating efficiency. In order to maintain the smooth operation of the equipment, it is necessary to increase the maintenance and servicing workload of the equipment maintenance personnel.

[0007] In order to solve the above problems, many improvement measures have been proposed in China. Chinese patents with patent numbers: CN202010019250.5, CN202210448379.7, CN202020707026.0, etc. have proposed some improvement measures. Most of them are aimed at solving the problem of difficulty in disassembly and installation of oil seals, and reducing the temperature of lubricating oil to delay the aging of oil seals. They cannot fundamentally solve the problems of cigarette contamination and machine failure caused by lubricating oil leakage, as well as the large workload of maintenance.

[0008] Chinese patent number CN202310357200.1 describes an oil-free spider arm for cigarette making machines. A set of synchronous pulleys is installed inside the spider arm's housing, connected by a long synchronous belt. This eliminates the need for lubricating oil inside the wheel body and eliminates the risk of cigarette contamination due to aging seals. This invention inherits the transmission principle of the existing epicyclic gear train, but replaces the gears with synchronous pulleys and the transition gears with synchronous belts, interconnecting the motion of the various pulleys within the wheel body. Theoretically, this invention can meet the motion requirements of a spider arm. The main similarity between this invention and a traditional spider arm is that the entire gear train is driven by a synchronous pulley connected to the wheel housing. The main shaft and the synchronous pulley fixed to the front end of the main shaft do not rotate. The implementation of this invention is difficult due to the use of a synchronous belt inside the wheel body. The tension of the synchronous belt needs to be checked and adjusted after a period of operation. The synchronous belt has a relatively short service life, and replacement and adjustment require disassembly of the wheel body, which is labor-intensive and time-consuming.

[0009] Therefore, designing a round rod product transfer device for tobacco production that does not require the use of lubricating oil while making machine assembly easier, shortening the time required for machine adjustment and inspection, and increasing the machine's transmission accuracy and stability has become a direction for further improvement.

[0039] like Figures 1 to 11 As shown, a bearing seat 6 is fixed to one side of the support plate 1, and a drive mechanism 2 is adapted to be penetrated on the bearing seat 6. The drive mechanism 2 includes a power member 7, a main shaft 8, a forward gear 9, a reverse gear 10, a crank 11, a transition gear 12 and a drive flange 13. The output end of the power member 7 is connected to the main shaft 8 in a transmission manner along the direction of the bearing seat 6. The power member 7 used in this embodiment is a common pulley or servo motor that can provide steering power. The main shaft 8 is sequentially and segmentedly sleeved with a forward gear 9, a reverse gear 10 and a crank 11. Transition gears 12 are respectively engaged on both sides of the lower end between the forward gear 9 and the reverse gear 10. The forward gear 9 and the reverse gear 10 rotate in opposite directions, while the reverse gear 10 rotates in the same direction as the crank 11. A drive flange 13 is adapted to be fitted on the crank 11. The forward gear 9, the reverse gear 10 and the transition gear 12 are all arranged in the bearing seat 6.

[0040] The drive flange 13 is in driving connection with the intermediate transmission device 3. Specifically, the intermediate transmission device 3 comprises a rear cover 14, a wheel body 15, a front cover 16, a connecting plate 17, and a crankshaft 18. The rear cover 14, wheel body 15, and front cover 16 are rigidly connected in sequence. A cavity is formed between the rear end of the wheel body 15 and the rear cover 14. Multiple connecting plates 17 are adapted to be installed in the cavity. The rear ends of the connecting plates 17 are fixedly connected to the drive flange 13 via stud bolts 30. Multiple through-holes are uniformly and correspondingly formed along the circumference of the front end of the wheel body 15 and the front cover 16. The crankshaft 18 is installed in these through-holes. The front end of the crankshaft 18 is connected to the front transmission device 4. A tension sleeve 26 is also embedded in the wheel body 15 and is mounted on the front end of the main shaft 8. The eccentricity of the crank 11 is the same as that of the crankshaft 18.

[0041] The intermediate transfer device 3 is provided with a front-end transmission device 4. Specifically, the front-end transmission device 4 includes a transmission arm 19, a small pulley shaft 20, a synchronous belt 21, a hollow pulley 22, and a suction claw 23. The front end of the crankshaft 18 is transmission-connected to the transmission arm 19. A rotatable small pulley shaft 20 is provided within the transmission arm 19. The rear end of the small pulley shaft 20 extends into the rear cover 14 of the wheel body 15 and is fixed thereto by screws. The small pulley shaft 20 is transmission-connected to the hollow pulley 22 via the synchronous belt 21. The front end of the hollow pulley 22 is fixedly connected to the suction claw 23. In this embodiment, the number of teeth on the small pulley shaft 20 is half that of the hollow pulley 22.

[0042] At least one arc-shaped suction nozzle 24 is provided at the front end of the suction claw 23, and a through slot 25 is provided in the suction claw 23, which is connected to the suction nozzle 24. The suction claw 23 moves along an elliptical trajectory and can maintain a horizontal state to realize the conveying action of the product 34.

[0043] When the suction claw 23 moves clockwise along the center line of the wheel body 15, it rotates counterclockwise around the center of the transmission arm 19 and the small pulley shaft 20.

[0044] An airflow channel connects the front-end transmission device 4 to the intermediate transfer device 3. The crankshaft 18 of the intermediate transfer device 3, through a connecting plate 17, connects with the drive flange 13, and the crank 11 to form a multiple-prong mechanism with a double crank 11. Specifically, the power element 7 drives the main shaft 8 clockwise, driving the forward gear 9 clockwise. This motion is transmitted through two transition gears 12 to the reverse gear 10 loosely mounted in the middle of the main shaft 8. Since the reverse gear 10 is fixed to the crank 11, it synchronously drives the crank 11 to rotate counterclockwise, which in turn drives the drive flange 13.

[0045] A suction cleaning mechanism 5 is provided on the outside of the front conveyor 4. This mechanism is used to absorb the product 34 or maintain a smooth airflow path. Specifically, the suction cleaning mechanism 5 includes a negative pressure suction seat 27, a cleaning seat 28, and a vacuum port 29. The negative pressure suction seat 27 and the cleaning seat 28 are fixed to opposite corners of the support plate 1. One end of the cleaning seat 28 is connected to the vacuum port 29. One end of the negative pressure suction seat 27 and the other end of the cleaning seat 28 are respectively attached to the outer ends of the airflow path.

[0046] A plurality of square holes 31 are uniformly provided radially on the wheel body 15, an L-shaped channel 32 is provided in the crankshaft 18, a Z-shaped channel 33 is provided in the conveying arm 19, and a straight channel 36 is provided in the hollow pulley 22. The square holes 31, L-shaped channel 32, Z-shaped channel 33, straight channel 36, through groove 25 and suction nozzle 24 are connected in sequence to form an airflow channel.

[0047] The product 34 described in this embodiment can be a round rod-shaped cigarette or filter rod or other round rod-shaped items that appear in the production of cigarettes, and this set of equipment can be used for all of them.

[0048] The working principle of the present invention is as follows:

[0049] During operation, the power member 7 drives the main shaft 8 to drive the forward gear 9 to rotate clockwise, and through the cooperation of the two transition gears 12, it drives the reverse gear 10 and the crank 11 to rotate counterclockwise, and drives the driving flange 13 installed on the crank 11. The stud bolts 30 of the driving flange 13 are fixed to the connecting plate 17, thereby continuously driving the multiple crankshafts 18 installed on the wheel body 15 to rotate counterclockwise;

[0050] The negative pressure passes through the negative pressure suction seat 27, the square hole 31 on the surface of the wheel body 15, the L-shaped channel 32 on the crankshaft 18, along the Z-shaped channel 33 of the conveying arm 19, and through the through groove 25 in the suction claw 23, and finally reaches the arc-shaped suction nozzle 24 of the suction claw 23, sucking the surface of the product 34 that has been transferred to the V-shaped guide rail 35, and continues to rotate to transfer the product 34 to the cigarette receiving wheel of the filter tip assembling machine (not shown in this figure).

[0051] When the device needs to be cleaned, the corresponding square hole on the wheel body 15 is rotated to the corresponding position of the cleaning air seat 28, and the vacuum port 29 is connected. The smoke and dust in the air flow channel are blown out by positive pressure air, so that the air flow channel is unobstructed, ensuring that the device is stable and reliable when conveying products 34.

[0052] The present invention not only eliminates the use of lubricating oil in the wheel body 15 of the intermediate transfer device 3, but also utilizes the cooperation between the intermediate transfer device 3 and the front-end transfer device 4 to realize multiple parallel double-link mechanisms. The rotation of the main shaft 8 drives the transmission parts, driving the crank 11 in the middle of the main shaft 8. The crank 11 drives the multiple crankshafts 18 to rotate through the multi-link mechanism. The transmission accuracy of the entire device is greatly improved compared with the existing technology, and the transmission stability is more durable, which can more accurately adsorb and transfer the round rod-shaped products 34 for tobacco production. The entire device is easy to assemble and adjust, has high operational stability, and a longer service life. In addition, the airflow channel is shorter than that of the existing technology, so the positive pressure cleaning effect and the negative pressure adsorption effect of the product 34 are better, and the adsorption and delivery of the product 34 are more stable and less likely to fall.

[0053] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
