Description

Technical Field

[0001] The present application relates to the technical field of cigarette marking, and in particular to a fully automatic cigarette ring marking instrument. Background Art

[0002] During the production process, cigarette factories usually use smoking machines to extract smoke from cigarettes to test various smoke indicators. Before installing the cigarettes in the smoking machine, they need to mark the outer surface of the cigarettes to calibrate the length of the retained cigarette butts. The most widely used marking method is: align the cigarettes and a ruler, determine the marking position according to the scale lines of the ruler, and then use a pen to directly mark the outer surface of the cigarette. This method has certain disadvantages in practice. When the pen tip marks the outer surface of the cigarette, it is easy to exert excessive force on the outer surface of the cigarette, causing local deformation of the cigarette or even damage to the cigarette paper, thereby affecting the normal drawing of the cigarette by the subsequent smoking machine. Utility Model Content

[0003] The purpose of this application is to provide a fully automatic cigarette ring marking instrument, which can spray ink on cigarettes in an inkjet manner without generating deformation force on the cigarettes, thereby effectively solving the shortcomings of the existing technology.

[0004] To this end, the present application provides a fully automatic cigarette ring marking instrument, comprising:

[0005] The conveying path is extended along a first direction, and the cigarettes can move axially along the extending direction of the conveying path;

[0006] The pushing component is adjustable along the extension direction of the conveying path to push the cigarettes to move on the conveying path;

[0007] A first rotating roller and a second rotating roller, wherein the first rotating roller and the second rotating roller are arranged in parallel at one end of the conveying path;

[0008] The inkjet head is arranged close to the first rotating roller and the second rotating roller;

[0009] The pushing component pushes the cigarettes on the conveying path onto the first roller and the second roller. The first roller and the second roller drive the cigarettes to rotate, and the inkjet head sprays ink to mark the rotating cigarettes.

[0010] In some possible implementations, a groove is provided on the top of the conveying path, and the groove runs in a first direction. On a cross section of the groove, the height of the groove gradually increases from the middle of the groove to both sides.

[0011] In some possible implementations, the first roller and the second roller rotate in the same direction, and are spaced apart from each other so that a space for accommodating cigarettes is formed above the first roller and the second roller.

[0012] In some possible implementations, the height of the first roller at one end close to the conveyor path is lower than the height of the top of the conveyor path, the height of the first roller at one end away from the conveyor path is higher than the height of the other end of the first roller, and the second roller and the first roller are symmetrically arranged relative to the vertical plane.

[0013] In some possible implementations, the vertical plane where the middle extension line of the groove is located is a symmetry plane between the first roller and the second roller.

[0014] In some possible implementations, a mounting frame is further included, and the inkjet head is disposed on the mounting frame, and the height of the inkjet head on the mounting frame is adjustable.

[0015] In some possible implementations, the pushing assembly includes a movable platform that can be adjusted along a first direction. The movable platform is provided with a contact arm, and the contact arm is used to push the cigarette to move along the conveying path.

[0016] In some possible implementations, the system further includes a driving component configured to drive the mobile platform to adjust along the first direction.

[0017] In some possible implementations, it further includes a scale grating and a grating reading head that cooperate with each other, the scale grating is arranged along the first direction, and the grating reading head is arranged on the moving platform.

[0018] In some possible implementations, a feeding assembly is further included, which is arranged close to the conveying path and is used to feed cigarettes one by one to the conveying path.

[0019] In some possible implementations, the feeding assembly includes a material trough, which has a feed port and a discharge port. The discharge port is located above the conveying path, and a cigarette channel is formed between the feed port and the discharge port. The cigarette channel is provided with a conveying drum wheel, and a cigarette groove is provided on the periphery of the conveying drum wheel. The conveying drum wheel rotates to transfer cigarettes near the feed port to near the discharge port.

[0020] In some possible implementations, a collecting device is further included, which is located below the first roller and the second roller, and the pushing component pushes the cigarettes on the first roller and the second roller into the collecting device.

[0021] According to the fully automatic cigarette ring marking instrument provided in the embodiment of the present application, the pushing component pushes the cigarettes on the conveyor path onto the first roller and the second roller. The coordinated rotation of the first roller and the second roller can make the cigarettes above rotate circumferentially. The inkjet head uses ink to mark the rotating cigarettes, and will not generate force on the outer surface of the cigarettes. It can effectively prevent the cigarettes from being deformed, which is beneficial to subsequent detection. Moreover, the inkjet marking during the rotation of the cigarettes can mark the entire circumference of the cigarettes, which is more conducive to the observation and calibration of the markings on the outer surface of the cigarettes. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 This is a schematic diagram of the structure of the fully automatic cigarette ring marking instrument provided in an embodiment of the present application. DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] like Figure 1 As shown, the embodiment of the present application provides a fully automatic cigarette ring marking instrument, which is used in the cigarette marking process. In the process of cigarette production, the cigarette factory needs to detect various indicators in the smoke generated by the burning of cigarettes. The smoke detection is completed with the help of a smoking machine. The filter section of the cigarette is installed on the smoking machine, and then the cigarette is lit. The smoking machine draws and collects the smoke, and then the smoke is tested. When the smoke generated by the burning of the cigarette is smoked, there are clear requirements for the burning length of the cigarette, that is, there are requirements for the length of the cigarette butt that needs to be retained when the cigarette is burned. Furthermore, before the cigarette is installed on the smoking machine, it is necessary to mark the outer surface of the cigarette to calibrate the length of the retained cigarette butt. When the smoking machine draws the smoke, the cigarette is The burning of a cigarette stops at the marking mark. The current marking method usually involves aligning the cigarette with a ruler, determining the marking position according to the scale lines on the ruler, and then marking the outer surface of the cigarette with a pen. This method has certain defects in practice. When using a pen to mark the outer periphery of the cigarette, the pen tip exerts a large force on the outer surface of the cigarette, which causes local deformation of the cigarette and even damage to the cigarette paper. The local deformation of the cigarette paper and the damage to the cigarette paper will affect the normal smoking of the subsequent smoking machine and are not conducive to the collection of smoke. The fully automatic cigarette paper ring marking instrument of this application is intended to avoid the deformation of the cigarette and the damage of the cigarette paper during the marking process of the cigarette, so as to facilitate the subsequent smoking of the smoke generated by the burning of the cigarette by the smoking machine.

[0025] The fully automatic cigarette ring marking instrument includes a conveying path 100, a pushing component, a first roller 201, a second roller 202 and an inkjet head 300. The conveying path 100 is extended along a first direction. The conveying path 100 is used to convey cigarettes. The cigarettes can move axially along the extension direction of the conveying path 100. The axial movement direction of the cigarettes on the conveying path 100 is parallel to the first direction. The pushing component can adjust the position along the extension direction of the conveying path 100. The pushing component pushes the cigarettes to move on the conveying path 100 through position adjustment. The first roller 201 and the second roller 202 can both rotate. The first roller 201 and the second roller 202 are arranged side by side at one end of the conveying path 100. The inkjet head 300 is close to the first roller 201 and the second roller 202. A first roller 201 and a second roller 202 are provided. In the running state, the pushing component can push the cigarettes on the conveying path 100 onto the first roller 201 and the second roller 202. The first roller 201 and the second roller 202 rotate in coordination to drive the cigarettes to rotate, and the inkjet head 300 sprays ink to mark the rotating cigarettes. In this embodiment, the inkjet head 300 uses inkjet to mark the outer surface of the cigarettes, which will not generate excessive force on the cigarettes, can effectively avoid deformation of the cigarettes, and will not cause damage to the cigarette paper, which is conducive to the normal smoking of the subsequent smoking machine. Moreover, the cigarettes are rotated to complete the marking, so that the entire cigarette is marked in a circle. The marking can be intuitively seen at all angles, and observation is more convenient.

[0026] Preferably, a workbench 90 can be provided, the conveying path 100 is provided on the workbench 90, the first roller 201 and the second roller 202 are rotatably provided on the workbench 90, both ends of the first roller 201 and the second roller 202 are rotatably installed on the workbench 90 through mounting components such as brackets. Taking the first roller 201 as an example for explanation, the bracket on the first roller 201 is horizontally outward, that is, horizontally extending in a direction away from the second roller 202 and then vertically extending downward and connected to the workbench 90 to prevent interference with the movement of the cigarettes. The first roller 201 and the second roller 202 have the same rotation direction, both of which rotate counterclockwise or clockwise. The first roller 201 rotates in a direction away from the second roller 202. The roller 201 and the second roller 202 are arranged at intervals, and the upper space between the first roller 201 and the second roller 202 is used to axially accommodate cigarettes. The cigarettes fall downward onto the first roller 201 and the second roller 202. When the first roller 201 and the second roller 202 rotate synchronously, the cigarettes are rotated. For this purpose, the first roller 201 and the second roller 202 are each driven by a separate drive motor, and the drive motor drives the first roller 201 and the second roller 202 through chains, synchronous belts, etc. The drive motors are arranged on both outer sides, and components such as chains and synchronous belts extend outward to avoid affecting the movement of the cigarettes. The principle is the same as the setting of the bracket used for installing the first roller 201 in the above-mentioned method.

[0027] Preferably, a groove is provided at the top of the conveying path 100, and the groove is provided along the extension direction of the conveying path 100, and the direction of the groove is the first direction. On the cross section of the groove direction, the height of the top of the groove gradually increases from the middle of the groove to the two sides. For example, the cross section of the groove can be V-shaped, so that the middle part of the groove is lower, and the cigarette can be stably in the groove for axial movement, and the groove extends along the first direction to the top of the entire conveying path 100. In this embodiment, when the pushing component pushes the cigarette to move axially along the groove, when the cigarette moves to the end of the conveying path 100, it continues to push the cigarette, so that the cigarette is axially and gradually transferred between the first roller 201 and the second roller 202, until the cigarette completely falls between the first roller 201 and the second roller 202, and then the first roller 201 and the second roller 202 rotate simultaneously, thereby causing the upper cigarette to rotate, and the inkjet head 300 performs annular inkjet marking on the outer periphery of the cigarette.

[0028] Preferably, an ink tank and an ink supply tube can also be provided, an ink pump is provided on the ink supply tube, one end of the ink supply tube is connected to the ink tank, and the other end of the ink supply tube is connected to the inkjet head 300. The ink tank contains ink and then supplies ink to the inkjet head 300.

[0029] More preferably, when the groove on the conveyor path 100 is V-shaped, the vertical plane where the extension line of the middle bottom of the groove is located is the symmetrical plane of the first roller 201 and the second roller 202. Taking the first roller 201 as an example, one end of the first roller 201 is close to the end of the conveyor path 100, and the other end of the first roller 201 extends in the direction of the principle conveyor path 100. The height of the end of the first roller 201 close to the conveyor path 100 is lower than the height of the top of the conveyor path 100, that is, the end of the first roller 201 is lower than the height of the groove on the conveyor path 100, and the height of the end of the first roller 201 away from the conveyor path 100 is higher than the height of the other end of the first roller 201, that is, the first roller 201 close to the conveyor path 100 The height of one end of the first roller 201 is lower than that of the other end of the first roller 201, and the height difference is 2-3 mm, so that the first roller 201 is slightly tilted away from the end of the conveying pipe, and the second roller 202 is symmetrical with the second roller 202 relative to the vertical plane. In this way, the first roller 201 and the second roller 202 are in a slightly inclined state. When the cigarette moves onto the first roller 201 and the second roller 202, under the action of gravity, the cigarette is driven to rotate by the first roller 201 and the second roller 202 and has a tendency to move toward one side of the conveying path 100. As a result, one end of the cigarette can slightly abut against the end of the conveying path 100. In this way, the cigarette will not be axially offset during rotation, making the inkjet marking more regular.

[0030] Preferably, the outer surface of the first roller 201 and the outer surface of the second roller 202 can be provided with anti-slip grooves or an anti-slip layer. The anti-slip grooves or the anti-slip layer contact the cigarette, which can increase the friction between the cigarette and the cigarette, making the rotation of the cigarette smoother. The anti-slip grooves are convex lines or concave grooves, and the anti-slip layer can be a silicone outer layer or a rubber outer layer.

[0031] Preferably, the mounting frame 301 is further included, and the mounting frame 301 is set on the workbench 90. The inkjet head 300 is mounted on the mounting frame 301. The height of the inkjet head 300 on the mounting frame 301 can be adjusted. For example, the inkjet head 300 can be mounted on the mounting frame 301 by a telescopic rod, or the inkjet head 300 can be mounted on the mounting frame 301 by a waist-shaped groove or a bolt to achieve the height adjustment of the inkjet head 300. In the vertical direction, the position of the inkjet head 300 corresponds to the first roller 201 and the second roller 202. In the middle, that is, in the vertical direction, the inkjet head 300 is facing downwards to cope with cigarettes of different specifications. When the first roller 201 and the second roller 202 are in the position, after the cigarette moves between the first roller 201 and the second roller 202, one end is against the end of the conveying path 100. The relative position of the cigarette is fixed, and the marking position depends on the position of the inkjet head 300 along the first direction. Furthermore, the horizontal position of the inkjet head 300 along the first direction on the mounting frame 301 can be adjusted, thereby adjusting the marking position.

[0032] The pushing assembly includes a moving platform 401, which is adjustable along a first direction and is arranged on a workbench 90. The moving platform 401 can be adjusted to move back and forth along the first direction on the workbench 90. A contact arm 402 is arranged on the moving platform 401, and the contact arm 402 is used to push the cigarette along the conveying path 100. The driving assembly also includes a driving assembly for driving the moving platform 401 to move. For example, the driving assembly can be a ball screw driving method. The driving assembly includes a threaded rod 403, which is extended along the first direction and is arranged on the workbench 90. The threaded rod 403 is rotatably mounted on the workbench On the table 90, the movable platform 401 is sleeved on the threaded rod 403, and the movable platform 401 and the threaded rod 403 are threadedly matched, and a slide rail 404 is provided on the workbench 90, and a slide groove is provided on the movable platform 401, and the slide groove and the slide rail 404 cooperate, and then by rotating the threaded rod 403, the reciprocating movement adjustment of the movable platform 401 can be realized, and the threaded rod 403 can be driven to rotate by a driving motor, and one end of the contact arm 402 is connected to the movable platform 401, and the other end of the contact arm 402 extends toward the direction of the conveying path 100 and extends to the middle position of the groove on the conveying path 100, so as to be able to push the cigarettes on the conveying path 100.

[0033] When the axes of the first roller 201 and the second roller 202 are both horizontal, the marking instrument also includes a scale grating 501 and a grating reading head 502 that cooperate with each other. The scale grating 501 is set on the workbench 90 along the first direction, and the grating reading head 502 is set on the movable platform 401. When the movable platform 401 moves, the grating reading head 502 moves along the scale grating 501, and then the moving distance of the movable platform 401 can be measured. According to the required marking position, the cigarette is pushed onto the first roller 201 and the second roller 202, and the movable platform 401 continues to move, so that the contact arm 402 continues to push the cigarette to move on the first roller 201 and the second roller 202 until it moves to the specified position. At this time, the position of the inkjet head 300 relative to the cigarette is the required marking position. In this way, with the cooperation of the scale grating 501 and the grating reading head 502, the marking position is determined according to the moving distance of the movable platform 401.

[0034] More preferably, it also includes a feeding assembly, which is arranged near the conveying path 100 and is used to convey cigarettes one by one to the conveying path 100. After the feeding assembly conveys a cigarette to the conveying path 100, the contact arm 402 pushes the cigarette to the first roller 201 and the second roller 202, the inkjet head 300 completes the marking, and then the contact arm 402 returns to the initial position, and the feeding assembly conveys the next cigarette to the conveying path 100, and then the contactor pushes the end of the cigarette to move axially to the first roller 201 and the second roller 202, and the process is repeated.

[0035] In one example, the feeding assembly includes a trough 600, which has a feed port and a discharge port. The discharge port is located above the conveying path 100. Cigarettes enter from the feed port and are discharged from the discharge port, thereby realizing the delivery of cigarettes to the conveyor. A cigarette channel is formed between the feed port and the discharge port in the trough 600. A conveying drum 61 is provided in the cigarette channel. The conveying drum 61 is cylindrical. A plurality of cigarette slots 610 are provided on the periphery of the conveying drum 61. The cigarette slots 610 are arranged along the axial direction of the conveying drum 61. When the conveying drum 61 rotates, the cigarettes near the feed port in the trough 600 can be transferred to a position near the discharge port. At, the cigarettes fall from the discharge port onto the conveyor path 100. In this embodiment, when the conveyor drum 61 is not rotating, the conveyor drum 61 blocks the cigarette channel and the cigarettes cannot fall out of the discharge port. When the conveyor drum 61 rotates, the cigarettes are transported in the cigarette channel driven by the cigarette groove 610 on the conveyor drum 61, and fall onto the conveyor path 100 through the discharge port. The rotation and transportation of the conveyor drum 61 are controlled by the driving motor to adapt to the moving frequency of the mobile platform 401 to form a continuous line. The axial direction of the conveyor drum 61 is parallel to the first direction, so that the cigarettes can be transferred smoothly to the conveyor path 100.

[0036] More preferably, a collecting device 700 is further included, which can be a box body, etc. The collecting device 700 is located below the first roller 201 and the second roller 202. After the cigarettes on the first roller 201 and the second roller 202 are marked, the contact arm 402 continues to push the cigarettes, pushing the cigarettes out of the first roller 201 and the second roller 202 and dropping them into the collecting device 700, and then the contact arm 402 returns. In this way, automatic and continuous marking is formed, which is conducive to improving the efficiency of cigarette marking. In this embodiment, when the first roller 201 and the second roller 202 are in an inclined state, for the height of the contact arm 402, the contact arm 402 will not interfere with the first roller 201 and the second roller 202 during the process of the contact arm 402 pushing the cigarettes to the collecting device 700.

[0037] In some embodiments, as an alternative to the first roller 201 and the second roller 202, the conveying path 100 extends directly to the collection device 700, and a mechanical gripper is provided on the contact arm 402. When the cigarette falls onto the conveying path 100, the mechanical gripper grabs the cigarette, and then the contact arm 402 moves toward the direction of the inkjet head 300. The mechanical gripper can then rotate the cigarette in a circular direction, or enable the inkjet head 300 to complete a circular marking on the cigarette. In this embodiment, the marking position on the cigarette can be achieved by measuring the distance of the scale grating 501 and the grating reading head 502. After the cigarette is marked, the contact arm 402 continues to drive the mechanical gripper to move toward the collection device 700 until the cigarette moves above the collection device 700, and the mechanical gripper releases the cigarette, allowing the cigarette to fall to the collection device.
