Description

Technical Field

[0001] This invention relates to a conveying device, and more particularly to a tobacco pack conveying device. Background Technology

[0002] The cigarette pack conveying device is located at the connection between the small-pack film packaging machine and the upstream automatic cigarette storage cabinet. A continuously rotating cigarette pack separating wheel inside the conveying device receives cigarette packs from the tail of the discharge belt of the automatic cigarette storage cabinet and conveys them one by one to the cigarette pack track of the small-pack film packaging machine. Then, a horizontally rotating conveyor wheel receives the cigarette packs conveyed by the cigarette pack separating wheel and sends them to the pusher of the lug-type chain. The pushers of the drag chain then transport the cigarette packs forward along the track.

[0003] Because the FOCKE350 small pack dispenser and cigarette storage cabinet discharge four packs adjacent to each other at a time, the packs are stacked sequentially at the inlet of the separator wheel. The clamping mechanism presses the packs firmly onto the input belt to ensure that the packs can be smoothly pushed along the arc-shaped channel by the separator wheel. During the initial 90° rotation of the packs from a horizontal position, the side of the rotating pack will scrape against the side of the adjacent, clamped pack, potentially causing white marks and resulting in defective packs. Excessive pressure from the clamping device on both ends of the pack can cause wrinkles in the cigarettes inside. Especially when the abrasion resistance index of the ink layer on the label paper of the small box is at the lower limit of the process standard range, continuous white stains will appear on the sides of the small box. Summary of the Invention

[0004] The purpose of this invention is to provide a cigarette pack conveying device to solve the technical problems in the prior art. It can effectively solve the problems of white residue on the sides and wrinkles on the cigarettes during the cigarette pack conveying process, thus ensuring product quality.

[0005] The present invention provides a cigarette pack conveying device, including a cigarette pack track, the output end of the cigarette pack track being connected to the input end of a transition plate, the output end of the transition plate being connected to a cigarette pack separation device, and a cigarette pack acceleration separation device and a cigarette pack pushing device being provided on both sides of the transition plate.

[0006] In the aforementioned cigarette pack conveying device, preferably, a first proximity switch, a second proximity switch, and a third proximity switch are sequentially arranged on the side wall of one side of the cigarette pack track, wherein the third proximity switch is arranged close to the transition plate.

[0007] In the aforementioned cigarette pack conveying device, preferably, the cigarette pack accelerating separation device includes a first driving wheel, a second driving wheel, a first driven wheel, a second driven wheel, a first toothed belt, and a second toothed belt. The first driving wheel and the first driven wheel are located on one side of the transition plate, and the first toothed belt is installed on the first driving wheel and the first driven wheel. The second driving wheel and the second driven wheel are located on the other side of the transition plate, and the second toothed belt is installed on the second driving wheel and the second driven wheel. The first driving wheel and the second driving wheel are simultaneously connected to a first stepper motor.

[0008] In the aforementioned cigarette pack conveying device, preferably, the surfaces of the first toothed belt and the second toothed belt are both perpendicular to the plane where the transition plate is located.

[0009] In the aforementioned cigarette pack conveying device, preferably, the cigarette pack pushing device includes a third drive wheel, a fourth drive wheel, a third driven wheel, a fourth driven wheel, a third toothed belt, and a fourth toothed belt. The third drive wheel and the third driven wheel are located on one side of the transition plate, and the third toothed belt is mounted on the third drive wheel and the third driven wheel. The fourth drive wheel and the fourth driven wheel are located on the other side of the transition plate, and the fourth toothed belt is mounted on the fourth drive wheel and the fourth driven wheel. The shafts of the third drive wheel and the fourth drive wheel are fixedly connected by a connecting shaft. A driven gear is fixed on the connecting shaft, and a drive gear is fixed on the output shaft of the second stepper motor. The drive gear is connected to the driven gear through a chain.

[0010] In the aforementioned cigarette pack conveying device, preferably, the top surfaces of the third toothed belt and the fourth toothed belt are flush with the top surface of the transition plate, and a plurality of first pushers are equally spaced on the belt surfaces of the third toothed belt and the fourth toothed belt.

[0011] Preferably, the aforementioned cigarette pack conveying device further includes a cover plate, which is located above the third toothed belt and the fourth toothed belt, and the cover plate is an organic glass plate with a brush on the bottom surface.

[0013] Compared with existing technologies, this invention includes a cigarette pack track, the output end of which is connected to the input end of a transition plate. The output end of the transition plate is connected to a cigarette pack separation device. A cigarette pack acceleration separation device and a cigarette pack pushing device are arranged on both sides of the transition plate. This invention, by cooperating with the transition plate, ensures a certain spacing between closely packed cigarette packs. Then, through the cooperation of the cigarette pack pushing device and the transition plate, the cigarette packs are fed one by one into the cigarette pack separation device. This prevents adjacent cigarette packs from contacting each other, solving the problem of white marks caused by friction between cigarette packs in existing technologies. By replacing the cigarette pack pressing device in existing technologies with the cigarette pack pushing device, not only is the cigarette pack conveying achieved, but the problem of wrinkles easily caused to cigarettes in existing technologies is also solved. The structure of this invention effectively ensures product quality. Attached Figure Description

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] Embodiments of the present invention: such as Figures 1-3 As shown, a cigarette pack conveying device includes a cigarette pack track 1, the output end of the cigarette pack track 1 is connected to the input end of a transition plate 2, the output end of the transition plate 2 is connected to a cigarette pack separation device 3, and a cigarette pack acceleration separation device and a cigarette pack pushing device are provided on both sides of the transition plate 2.

[0020] The cigarette pack track 1 is existing technology. Cigarette packs 24 are closely arranged on the track 1. When the cigarette packs 24 move to the connection point between the track 1 and the transition plate 2, both ends of the cigarette packs 24 connect to the cigarette pack accelerating separation device. Driven by the accelerating separation device, the cigarette packs 24 quickly move onto the transition plate 2, thus creating a certain distance between adjacent cigarette packs 24 on the transition plate 2. This prevents friction between adjacent cigarette packs 24 when they enter the cigarette pack separating device 3, effectively solving the problem of whitening caused by friction. This embodiment replaces the cigarette pack pressing device in the prior art with a cigarette pack pushing device, not only achieving cigarette pack transportation but also solving the problem of wrinkles easily caused to cigarettes in the prior art.

[0021] In one specific embodiment, a first proximity switch 4, a second proximity switch 5, and a third proximity switch 6 are sequentially arranged on the side wall of one side of the cigarette pack track 1. The third proximity switch 6 is located close to the transition plate 2. Specifically, the outer walls of the first proximity switch 4, the second proximity switch 5, and the third proximity switch 6 are all threaded, and they are all threadedly connected to the side wall of the cigarette pack track 1. The positions of the first proximity switch 4, the second proximity switch 5, and the third proximity switch 6 can be adjusted through the threaded connection, thereby ensuring the accuracy of detection. When the third proximity switch 6 detects a low signal, the cigarette pack separation device 3, the cigarette pack acceleration separation device, and the cigarette pack pushing device simultaneously stop.

[0022] Furthermore, the cigarette pack acceleration separation device includes a first drive wheel 7, a second drive wheel 8, a first driven wheel 9, a second driven wheel 10, a first toothed belt 11, and a second toothed belt 12. The first drive wheel 7 and the first driven wheel 9 are located on one side of the transition plate 2. The first toothed belt 11 is mounted on the first drive wheel 7 and the first driven wheel 9. The second drive wheel 8 and the second driven wheel 10 are located on the other side of the transition plate 2. The second toothed belt 12 is mounted on the second drive wheel 8 and the second driven wheel 10. The first drive wheel 7 and the second drive wheel 8 are simultaneously connected to the first stepper motor 13.

[0023] It should be noted that the first drive wheel 7, the second drive wheel 8, the first driven wheel 9, and the second driven wheel 10 are all mounted on the frame of the tobacco pack conveying device, which is not shown in the figure. The rotation axes of the first drive wheel 7, the second drive wheel 8, the first driven wheel 9, and the second driven wheel 10 are all oriented vertically, that is, the belt surfaces of the first toothed belt 11 and the second toothed belt 12 are perpendicular to the plane where the transition plate 2 is located. The first toothed belt 11 and the second toothed belt 12 are used to contact the two ends of the tobacco pack 24 and drive the tobacco pack 24 to move on the transition plate 2.

[0024] By simultaneously driving the first drive wheel 7 and the second drive wheel 8 with the first stepper motor 13, it can be ensured that the first toothed belt 11 and the second toothed belt 12 move at the same speed, thereby preventing the cigarette pack 24 from tilting during its movement on the transition plate 2.

[0025] Furthermore, the cigarette pack pushing device includes a third drive wheel, a fourth drive wheel, a third driven wheel, a fourth driven wheel, a third toothed belt 14, and a fourth toothed belt 15. The third drive wheel and the third driven wheel are located on one side of the transition plate 2, and the third toothed belt 14 is installed on the third drive wheel and the third driven wheel. The fourth drive wheel and the fourth driven wheel are located on the other side of the transition plate 2, and the fourth toothed belt 15 is installed on the fourth drive wheel and the fourth driven wheel. The shafts of the third drive wheel and the fourth drive wheel are fixedly connected by a connecting shaft. A driven gear is fixed on the connecting shaft. A drive gear is fixed on the output shaft of the second stepper motor. The drive gear is connected to the driven gear through a chain.

[0026] The third drive wheel, fourth drive wheel, third driven wheel, fourth driven wheel, and second stepper motor are not shown in the figure. They can be installed on the frame of the cigarette pack conveying device in a conventional manner. The third drive wheel and fourth drive wheel are arranged opposite each other, as are the third driven wheel and fourth driven wheel. The shafts of the third drive wheel, fourth drive wheel, third driven wheel, and fourth driven wheel all face horizontally. The top surfaces of the third toothed belt 14 and fourth toothed belt 15 are flush with the top surface of the transition plate 2. Multiple first pushers 16 are evenly spaced on the surface of the third toothed belt 14 and fourth toothed belt 15. The first pushers 16 on the third toothed belt 14 and fourth toothed belt 15 are one-to-one opposite each other. Preferably, a fourth proximity switch 23 is also provided at the position of the third toothed belt 14.

[0027] The third and fourth drive wheels are driven by the second stepper motor, ensuring that the third and fourth drive wheels rotate at the same speed. When the tobacco pack 24 is separated from the first toothed belt 11 and the second toothed belt 12, the bottom surface of the tobacco pack 24 moves onto the third toothed belt 14 and the fourth toothed belt 15, and is pushed by the first pusher 16 on them.

[0028] Furthermore, it also includes a cover plate 17, which is located above the third toothed belt 14 and the fourth toothed belt 15. The cover plate 17 is an organic glass plate with a brush on its bottom surface. The brush is 1.5 mm away from the top surface of the cigarette pack 24. By setting the cover plate 17, the cigarette pack 24 can be further prevented from tilting during movement, so that the cigarette pack 24 can accurately enter the cigarette pack separation device 3.

[0029] Furthermore, the tobacco pack separation device 3 includes a driven wheel 18, a driving wheel 19, a fifth toothed belt 20, a tobacco pack conveying guide rail 21, and a second pusher 22. The fifth toothed belt 20 is installed on the driven wheel 18 and the driving wheel 19, and the tobacco pack conveying guide rail 21 has its inlet end flush with the top surface of the transition plate 2.

[0030] The tobacco pack separation device 3 is existing equipment, therefore the working principle of the tobacco pack separation device 3 will not be described in detail in this embodiment. The distance between the end of the transition plate 2 and the tobacco inlet end of the tobacco pack conveying guide rail 21 is preferably 4mm.

[0031] It should be noted that the first proximity switch 4, the second proximity switch 5, the third proximity switch 6, the fourth proximity switch 23, the first stepper motor 13, the second stepper motor, and the cigarette pack separation device 3 are all electrically connected to the PLC programmable controller.

[0032] The working principle of this invention is as follows: When the cigarette pack 24 output from the cigarette pack track 1 passes through the first proximity switch 4, the second proximity switch 5, the third proximity switch 6, and the fourth proximity switch 23, they generate high-level signals and send them to the PLC programmable controller. When they cannot detect the cigarette pack 24, they send low-level signals to the PLC programmable controller. After leaving the cigarette pack track 1, the cigarette pack 24 moves to the transition plate 2. At the same time, both ends of the cigarette pack 24 contact the first toothed belt 11 and the second toothed belt 12. Since the moving speed of the first toothed belt 11 and the second toothed belt 12 is faster than the conveying speed of the cigarette pack track 1, the cigarette pack 24 moves quickly after contacting the first toothed belt 11 and the second toothed belt 12 and maintains a certain distance from the next cigarette pack 24. The distance between two adjacent cigarette packs 24 is greater than the speed of the first stepper motor 13. After the tobacco pack 24 leaves the first toothed belt 11 and the second toothed belt 12, the bottom surface of the tobacco pack 24 moves above the third toothed belt 14 and the fourth toothed belt 15. The first pusher 16 on the third toothed belt 14 and the fourth toothed belt 15 pushes the tobacco pack 24 to continue moving forward. When the tobacco pack 24 enters the upper end of the tobacco pack conveying guide rail 21, the first pusher 16 separates from the tobacco pack 24. At this time, the second pusher 22 pushes the tobacco pack 24 to move along the tobacco pack conveying guide rail 21 to the next process.

[0033] If the third proximity switch 6 does not detect the cigarette pack 24 within the specified time, the third proximity switch 6 sends a low-level signal to the PLC programmable controller, and the PLC programmable controller controls the first stepper motor 13, the second stepper motor and the cigarette pack separation device 3 to stop synchronously.

[0034] When the third proximity switch 6 detects cigarette pack 24, it sends a high-level signal to the PLC programmable controller. If the time interval between two adjacent high-level signals from the first proximity switch 4 is less than the high-speed operating speed / 4 / 60, the PLC programmable controller controls the cigarette pack acceleration separation device, cigarette pack pushing device, and cigarette pack separation device 3 to operate synchronously at high speed, increasing the speed by +40 packs / min. If the time interval between two adjacent high-level signals from the first proximity switch 4 is greater than or equal to the high-speed operating speed / 4 / 60, it indicates that the cigarette packs in front of the first proximity switch 4 are not arranged sequentially. At this time, if the time interval between two adjacent high-level signals from the second proximity switch 5 is less than or equal to the current high-speed speed / 4 / 60 (indicating that the equipment is operating normally and the number of cigarette packs in the conveying channel is large), the synchronous high-speed operating speed is maintained at +20 packs / min. If the time interval between two adjacent high-level signals from the second proximity switch 5 is greater than the current high-speed speed (packs / min) / 4 / 60 (indicating that there are fewer cigarette packs in the cigarette pack channel), the synchronous high-speed operating speed is reduced by -20 packs / min.

[0035] If the third proximity switch 6 does not detect the cigarette pack (detection at the lowest level signal) at the phase specified by the controller, the cigarette pack acceleration separation device, the pushing device, and the cigarette pack separation device will stop simultaneously.

[0036] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
