Description
Technical Field
[0001] The present invention belongs to the technical field of tobacco machinery, and particularly relates to a cigarette blank dropping and boxing device. Background Art
[0002] Traditional cigarette blanks
[0003] Currently, the common cigarette packages on the market are mainly paper cuboid boxes. Most cigarette blanks are also cylinders with the same diameter up and down, and cigarette packages are generally designed for cylindrical cigarette blanks. However, with the development and progress of the cigarette manufacturing process, unconventional cigarette blanks have emerged, such as cigarette blanks with a cylindrical filter tip and a square-columnar tobacco part. A conventional cigarette blank group requires a cuboid accommodation space, and an irregular cigarette blank group requires a trapezoidal accommodation space that is wider at the top and narrower at the bottom due to the different volumes of the upper and lower parts of the cigarette blank. If a conventional cigarette box is used to accommodate an irregular cigarette blank group, there will inevitably be a situation where the cigarette blank group is tightly packed at the top and loose at the bottom, with slits, resulting in the inability to fix the position and causing shaking during storage and transportation, leading to cigarette blank extrusion deformation and tobacco scattering. Therefore, the design of conventional cigarette boxes cannot meet the packaging requirements of irregular cigarette blanks, and special boxes need to be designed according to the specific shapes and volumes of irregular cigarette blanks and cigarette blank groups, such as Patent CN211766913U.
[0004] The traditional method of loading cigarette blanks into a box is as follows: First, the cigarette blanks are accommodated in a die box, a flat paper is used to surround the die box to form a box body, and then demolding is performed to wrap the cigarette blanks in a cuboid cigarette box.
[0005] However, for special-shaped boxes designed according to the specific shapes and volumes of irregular cigarette blanks and cigarette blank groups, how to load the cigarette blanks is a problem. To solve the above problems, the present invention is proposed. Summary of the Invention

[0058] The structure of the cigarette blank feeding and box loading device is as follows.
[0059] As Figures 1-3As shown, the cigarette dropping and box loading device 2 includes: a cigarette conveying bin 2.1 arranged from upstream to downstream, a blanking drum and a roller mechanism 2.2, a cigarette buffer bin 2.3, a cigarette gathering and positioning bin 2.4, a cigarette pushing mechanism 2.5, etc.
[0060] The cigarette conveying bin 2.1 is used for storing cigarettes and conveying the cigarettes 1 to the blanking drum and the roller mechanism 2.2 by means of a conveyor belt. The blanking drum and the roller mechanism 2.2 are used for conveying the cigarettes 1 in a counted form to the cigarette buffer bin 2.3. The cigarette buffer bin 2.3 is used for buffering the cigarettes 1 falling from the blanking drum and the roller mechanism 2.2, and discharging the cigarettes 1 to the cigarette gathering and positioning bin 2.4 at one time after accumulating a specified number of cigarettes 1. The cigarette gathering and positioning bin 2.4 is used for gathering and shaping the cigarettes 1 so that they can be smoothly inserted into the cigarette boxes in bundles. The cigarette pushing mechanism 2.5 is used for pushing the cigarettes 1 into the cigarette boxes.
[0061] The cigarette conveying bin 2.1 mainly includes: a driven belt roller 2.1.1, a transmission belt 2.1.2, a sliding seat plate 2.1.3, a linear guide rail 2.1.4, a bin frame 2.1.5, a blanking slope 2.1.6, a tobacco receiving drawer 2.1.7, a drawer chute 2.1.8, a proximity switch mounting block 2.1.9, a proximity switch 2.1.10, a driven belt roller bearing seat, a driven belt roller tensioning seat, a feeding position switch, a discharging position switch, a driving belt roller bearing seat, a driving belt roller, a cigarette conveying coupling, a cigarette conveying motor mounting bracket, a cigarette conveying driving stepping motor, and a spring plunger.
[0062] The functions of the above components of the cigarette conveying bin 2.1 are as follows: The cigarettes are conveyed towards the blanking drum and the roller mechanism 2.2 under the drive of the transmission belt 2.1.2. The driven belt roller tensioning seat can tension the transmission belt 2.1.2. The tobacco receiving drawer 2.1.7 is installed in the drawer chute 2.1.8 and is used for receiving the dropped tobacco. The entire bin frame 2.1.5 is connected to the sliding seat plate 2.1.3 through the linear guide rail 2.1.4. The entire bin frame 2.1.5 can slide to facilitate feeding and blockage removal. The proximity switch 2.1.10 is used to detect whether the bin frame 2.1.5 is pushed back to the correct working position. The spring plunger is used for positioning the bin frame 2.1.5. The feeding position switch and the discharging position switch can judge whether the material level in the bin is normal. The blanking slope 2.1.6 is inclined from upstream to downstream and abuts against the blanking drum and the roller mechanism 2.2, and is used for conveying the cigarettes to the blanking drum and the roller mechanism 2.2. The specific structure of the cigarette conveying bin 2.1 is as Figure 4 shown.
[0063] The blanking drum and the roller mechanism 2.2 mainly include: a drum driving stepper motor, a small gear, a cigarette counting switch bracket, a cigarette counting sensor, a roller driving motor, a motor mounting seat, a roller coupling, a roller bearing seat, a roller, an air duct, a large gear, a quick connector, a bearing left gland, a bearing, a grooved outer sleeve 2.2.15 of the drum, a drum air distribution shaft 2.2.16, a right transmission bearing gland, a right support bearing gland, and a drum outer circle gland tile.
[0064] The functions of each component of the blanking drum and the roller mechanism 2.2 are as follows: The cigarette counting sensor counts by detecting the presence or absence of cigarettes 1 in the grooves of the grooved outer sleeve 2.2.15 of the drum. The roller can brush out the extra cigarettes 1 that enter the grooves. The drum driving stepper motor drives the grooved outer sleeve 2.2.15 of the drum to rotate by driving the large gear and the right transmission bearing gland through the small gear. The outer surface of the grooved outer sleeve 2.2.15 of the drum has circumferentially arranged grooves for accommodating the cigarettes 1 transported from the blanking slope 2.1.6. The drum air distribution shaft 2.2.16 is arranged inside the grooves of the grooved outer sleeve 2.2.15 of the drum. The bottom of the grooves of the grooved outer sleeve 2.2.15 of the drum is provided with air vents. A number of downward blowing holes 2.2.16.2 are opened at one end of the drum air distribution shaft 2.2.16. When the grooved outer sleeve 2.2.15 of the drum rotates to make the blowing holes 2.2.16.2 communicate with the air vents at the bottom of the grooves of the grooved outer sleeve 2.2.15 of the drum, the blowing holes 2.2.16.2 can blow out the cigarettes 1 in the grooves for blanking. An approximately 165° air distribution annular groove 2.2.16.1 that penetrates upward is opened at the other end of the drum air distribution shaft 2.2.16, and a negative pressure is provided upward inside it. When the grooved outer sleeve 2.2.15 of the drum rotates to make the air distribution annular groove 2.2.16.1 communicate with the air vents at the bottom of the grooves of the grooved outer sleeve 2.2.15 of the drum, the air distribution annular groove 2.2.16.1 can make the negative pressure introduced by the air duct be distributed in a limited-angle area to ensure that the cigarettes 1 do not fall off in the grooves. The specific structure is as Figure 5 shown. Figure 5Schematic diagram of the grooved outer sleeve 2.2.15 of the moving drum and the air-distributing shaft 2.2.16 of the drum. During the working process, the grooved outer sleeve 2.2.15 of the drum rotates, and the air-distributing shaft 2.2.16 of the drum is fixed. When the grooved outer sleeve 2.2.15 of the drum carries the cigarette and rotates to a position where the groove of the grooved outer sleeve 2.2.15 is above the air-distributing annular groove 2.2.16.1, the groove communicates with the air-distributing annular groove 2.2.16.1, and there is negative pressure in the air-distributing annular groove 2.2.16.1, and the cigarette is adsorbed in the groove. When the grooved outer sleeve 2.2.15 of the drum carries the cigarette and rotates out above the air-distributing annular groove 2.2.16.1 and enters the blocking range of the outer circular pressing cover tile 2.2.19 of the drum, there is no negative pressure in the groove to adsorb the cigarette 1, but the outer circular pressing cover tile 2.2.19 of the drum blocks the cigarette 1 from separating from the groove. When the grooved outer sleeve 2.2.15 of the drum carries the cigarette and rotates out of the blocking range of the outer circular pressing cover tile 2.2.19 of the drum, the cigarette drops into the cigarette buffer bin 2.3. To prevent the cigarette from dropping, the air-blowing hole 2.2.16.2 blows air downward.
[0065] The cigarette buffer bin 2.3 mainly includes: a buffer bin box body, an optical fiber sensor, a blanking drawplate, a drawplate mounting block, a cylinder, and a cylinder support.

[0068] The functions of each component of the cigarette gathering and positioning bin 2.4 are: on the side of the cigarette inserting and guiding bell mouth 2.4.2 away from the movable left gathering block 2.4.7 and the movable right gathering block 2.4.9, there are thin inserts 2.4.2.1 distributed, which can be inserted into the cigarette box to facilitate the introduction of cigarettes. The lengths of the inserts 2.4.2.1 can be different to facilitate the insertion into special-shaped cigarette boxes.
[0069] The shapes of the movable left gathering block 2.4.7 and the movable right gathering block 2.4.9 are complementary and are arranged oppositely, and the cigarettes are gathered and positioned under the drive of their respective lead screw motors. The cigarette silk receiving drawer 2.4.8 can collect the cigarette silk dropped during the process. The specific structure is as Figures 8-9As shown. The movable left gathering block 2.4.7 and the movable right gathering block 2.4.9 are both movable and can be in a first position where they are away from each other and a second position where they are close to each other. In the second position, the two semi-circular notches of the movable left gathering block 2.4.7 and the movable right gathering block 2.4.9 are opposite to form a circular notch, and the circular notch coincides with the cigarette inserting inlet bell mouth 2.4.2 in the axial direction, so that the cigarette in the circular notch can be inserted into the cigarette case on the cigarette inserting inlet bell mouth 2.4.2. Figure 8 The schematic diagram shows the position of the cigarette gathering and positioning bin 2.4 in the cigarette blanking and box loading device 2. Behind the cigarette gathering and positioning bin 2.4 is the cigarette pushing mechanism 2.5, and above it is the cigarette buffer bin 2.3. Figure 10 The inserting piece 2.4.2.1 and the cigarette inserting inlet bell mouth 2.4.2 can be clearly seen. In order to facilitate the insertion of special-shaped cigarette cases, the inserting piece 2.4.2.1 is inclined towards the center of the cigarette inserting inlet bell mouth 2.4.2.
[0070] The cigarette pushing mechanism 2.5 mainly includes: a cigarette pushing piston head, a cigarette pushing piston rod, a cigarette pushing slider, a cigarette pushing driving connecting block, a cigarette pushing lead screw motor, a limit sensor, a lead screw motor mounting bracket, a linear guide rail, and a mounting substrate.
[0071] The functions of each component of the cigarette pushing mechanism 2.5 are: the cigarette pushing lead screw motor drives the cigarette pushing driving connecting block to drive the cigarette pushing slider, the cigarette pushing piston rod, and the cigarette pushing piston head to push the cigarettes in the cigarette gathering and positioning bin 2.4 into the cigarette case inserted on the cigarette inserting inlet bell mouth 2.4.2.
