Description

Technical Field

[0001] This invention relates to the field of cigarette production technology, and in particular to an automatic cigarette guiding device and a cigarette loading machine. Background Technology

[0002] The statements in this section merely refer to the background art related to this invention and do not necessarily constitute prior art.

[0003] Currently, the cigarette packing machine is initially operated manually. Due to the machine's complex structure and high cigarette drop area, manual guidance easily results in messy cigarettes that fail to meet quality requirements, leading to significant waste. Furthermore, the machine is typically operated by a single person. During initial operation, the need for manual guidance prevents the operator from monitoring the cigarette rolling and sealing unit, increasing the risk of downtime and impacting both operational efficiency and equipment safety.

[0004] In existing technologies, the automatic guidance of cigarettes is achieved by improving the original structure of the loading area of ​​the cigarette packing machine or designing an automatic cigarette receiving fixture. However, technicians believe that the cigarette guide block integrated into the cigarette packing machine occupies the guiding space, affecting the efficiency of automatic cigarette guidance. Therefore, when modifying the cigarette packing machine, the guide block is usually removed, which increases the difficulty of improving the loading area of ​​the cigarette packing machine.

[0005] Chinese patent publication number CN 114476524 A discloses an automatic cigarette receiving system for a cigarette tray loading machine, which achieves automatic cigarette delivery through the cooperation of a guiding mechanism, a conveying mechanism, and a drive structure. Patent publication number CN114852398 A discloses a cigarette guiding device for the cigarette storage compartment of a cigarette tray loading machine, which guides the cigarettes downwards by driving a receiving plate from the top to the bottom of the receiving channel, thus guiding the cigarette flow. However, both require changes to the original structure of the cigarette tray loading area, which is difficult and costly. Furthermore, when modifying the original structure of the loading area, the original cigarette guiding blocks will be removed. Without the support of the guiding blocks, the force on the cigarettes at the bottom of the buffer zone will increase, reducing the stability of the falling cigarette flow and potentially leading to quality risks such as cigarette deformation over long-term operation.

[0006] Chinese patent CN 115571677 A discloses a cigarette packing machine with a vertically moving cigarette receiving fixture below the feeding port. However, if the cigarette receiving fixture is applied to a cigarette packing machine equipped with a cigarette guide block, the cigarette packing machine still needs to be improved to achieve normal operation. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an automatic cigarette guiding device, a cigarette tray loading machine, and a method that independently achieves automatic cigarette guiding without altering the original functions and control system of the cigarette tray loading machine.

[0008] In a first aspect, the present invention provides an automatic cigarette guide device;

[0016] The threads on the X-axis lead screw are symmetrically arranged around the midpoint of the X-axis lead screw, and the guide roller is disposed on the side wall of the slider.

[0017] In some embodiments, the non-wound end of the main cigarette guide belt is provided with a guide tube, which is sleeved on the guide roller.

[0018] In some embodiments, a transparent baffle is also included, which is disposed on the main frame.

[0019] In some embodiments, the guide roller and the main cigarette guide belt are located outside the main frame.

[0020] In some embodiments, the trajectory guide groove is matched with the distribution position of the cigarette guide blocks inside the cigarette tray loading machine.

[0021] Secondly, the present invention provides a cigarette packing machine;

[0022] A cigarette packing machine includes the aforementioned automatic cigarette guiding device.

[0023] Thirdly, the present invention provides a method for using an automatic cigarette guide device;

[0024] A method of using an automatic cigarette guide device, based on the above-mentioned automatic cigarette guide device, includes the following steps:

[0025] S1. Place the automatic cigarette guide device inside the cigarette tray loading machine, below the cigarette buffer zone;

[0026] S2. Start the cigarette loading machine, and the cigarettes flow through the cigarette buffer zone and fall; start the automatic cigarette guiding device, and under the drive of the X-axis motion component and the Y-axis motion component, the main cigarette guide belt receives the cigarettes and moves from the starting point along the trajectory guide groove to the end point, completing the cigarette guiding work.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1.

[0040] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0041] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0042] Example 1

[0043] Existing automatic cigarette guiding devices often require modifications to the cigarette loading machine, which is difficult and costly, affecting cigarette production efficiency. Therefore, this invention provides an automatic cigarette guiding device.

[0044] Next, combined Figures 1-7 This embodiment discloses an automatic cigarette guiding device. The automatic cigarette guiding device includes a main frame 3, an X-axis motion component, and a trajectory guide groove 2. The main frame 3 is a cubic frame structure with a hollow design that runs through both the front and back sides, and a transparent baffle 8 is installed in front of it to prevent the cigarette from falling off during the guiding process. Y-axis motion components are vertically installed on both sides of the main frame 3, and two unwinding motors 9 are symmetrically fixed in the middle of the main frame 3. The output shaft of the unwinding motors 9 is wound with a main cigarette guide belt 11.

[0045] One end of the X-axis motion component is threadedly connected to the Y-axis motion component on one side, and the other end of the X-axis motion component is threadedly connected to the Y-axis motion component on the other side; the Y-axis motion component realizes the Y-axis motion of the X-axis motion component. Two guide rollers 1 are symmetrically connected on the X-axis motion component, and the guide rollers 1 correspond to the main cigarette guide belt 11. The trajectory guide groove 2 is vertically installed on the transparent baffle 8, located between the two unwinding motors 9. The guide rollers 1 pass through the trajectory guide groove 2 and are connected to the non-winding end of the corresponding main cigarette guide belt 11. The guide rollers 1 and the trajectory guide groove 2 are slidably connected, and the main body of the guide rollers 1 and the main cigarette guide belt 11 are located outside the main frame 3, which facilitates better reception of the cigarette stream 17.

[0046] Specifically, the Y-axis motion component includes a Y-axis servo motor 4 and a Y-axis lead screw 5. The Y-axis servo motor 4 is fixed to the top of the main frame 3, and the Y-axis lead screw 5 is vertically fixed inside the main frame 3. The output end of the Y-axis servo motor 4 passes through the main frame 3 and is coaxially connected to the Y-axis lead screw 5. Thus, the rotation of the Y-axis servo motor 4 drives the rotation of the Y-axis lead screw 5, realizing the Y-axis movement of the X-axis motion component. Here, the movements of the two Y-axis motion components are synchronized.

[0047] The X-axis motion assembly includes a fixed plate 7, which is horizontally positioned. One end of the fixed plate 7 is threadedly connected to a Y-axis lead screw 5 on one side, and the other end of the fixed plate 7 is threadedly connected to a Y-axis lead screw 5 on the other side. An X-axis servo motor 6 is fixed on the fixed plate 7. The output end of the X-axis servo motor 6 is connected to the X-axis lead screw via an X-axis synchronous belt 13. Two sliders 12 corresponding to the trajectory guide groove 2 are threadedly connected to the X-axis lead screw. The installation positions of the two sliders 12 are symmetrical about the midpoint along the length of the X-axis lead screw. The threads on the X-axis lead screw are also symmetrical about the midpoint along the length of the X-axis lead screw. That is, the rotation directions of the threads in the front and rear halves of the X-axis lead screw are opposite, thereby achieving mirror motion of the two sliders 12. The guide roller 1 is fixed to the side wall of the slider 12.

[0048] A guide tube is installed at the non-wound end of the main cigarette guide belt 11, and the guide tube is sleeved on the guide roller 1, making the connection between the non-wound end of the main cigarette guide belt 11 and the guide roller 1 more stable and preventing it from falling off during the cigarette guiding process. Two unwinding motors 9 are used to control the tension of the corresponding main cigarette guide belts 11 to achieve constant tension. The main body of the guide roller 1 and the main cigarette guide belt 11 is located outside the main frame 3. Once the device is installed inside the cigarette loading machine, it can be used without any other operation.

[0049] To supplement areas that the main cigarette guide belt cannot reach, as one implementation method, an auxiliary cigarette guide belt 10 is fixed below the guide roller 1. The auxiliary cigarette guide belt 10 guides the cigarettes to spread orderly to the bottom layer under the action of gravity.

[0050] The trajectory guide groove 2 is used to define the forward trajectory 20 of the guide roller 1, thereby guiding the moving end (non-winding end) of the cigarette guide belt to move along the set trajectory 20. In order to improve the guiding effect and disperse the pressure of the bottom layer of cigarettes, as one implementation method, the trajectory 20 of the trajectory guide groove 2 is matched with the distribution position of the cigarette guide blocks 15 in the cigarette loading machine, such as... Figure 2 , Figure 6 As shown, that is, the trajectory 20 of the trajectory guide groove 2 is designed along the distribution position of the cigarette guide block 15.

[0051] In this embodiment, the transparent baffle 8 is made of acrylic material.

[0052] The working principle of this embodiment is as follows:

[0053] When the equipment is in use, the automatic cigarette guide device is placed inside the cigarette loading machine, below the cigarette buffer zone 16. The starting point 18 of the main cigarette guide belt 11 is located at the lowest point in the middle of the cigarette buffer zone 16. The cigarette stream 17 falls through the cigarette buffer zone 16, and the main cigarette guide belt 11 receives the cigarettes and moves from the starting point along the trajectory guide groove 2 to the ending point 19, completing the cigarette guiding work.

[0054] Example 2

[0055] Based on the automatic cigarette guiding device described in the above embodiments, this embodiment also provides a cigarette tray loading machine. The cigarette tray loading machine is internally equipped with the automatic cigarette guiding device described in the above embodiments. Since the automatic cigarette guiding device has the above-mentioned technical effects, please refer to the above embodiments for the technical effects of the cigarette tray loading machine using the automatic cigarette guiding device.

[0056] A rear baffle 21 for the cigarette hopper is installed at the rear of the cigarette hopper. The rear baffle 21 contacts the cigarette filter end and is used to block the rear end of the cigarette. The automatic cigarette guide device is placed in the cigarette buffer drop area of ​​the cigarette hopper, below the cigarette buffer zone 16, without any bolts for fixation. After automatic guidance is completed, it can be easily removed without affecting the original function of the equipment. At this time, the transparent baffle 8 on the automatic cigarette guide device contacts the lit end of the cigarette and is used to block the front end of the cigarette. The distance between the rear baffle 21 of the cigarette hopper and the transparent baffle 8 is approximately the length of a cigarette.

[0057] Example 3

[0058] Based on the automatic cigarette guide device described in the above embodiments, this embodiment also provides a method for using the automatic cigarette guide device, including the following steps:

[0059] S1. Place the automatic cigarette guide device inside the cigarette tray loading machine, below the cigarette buffer zone 16.

[0060] Specifically, the automatic cigarette guide device can be placed directly on the cigarette tray loading machine. The automatic cigarette guide device is located below the cigarette buffer zone 16, and the main cigarette guide belt 11 receives the cigarette flow 17.

[0061] S2. Start the cigarette loading machine. The cigarette stream 17 falls through the cigarette buffer zone 16. Start the automatic cigarette guiding device. Driven by the X-axis motion component and the Y-axis motion component, the main cigarette guide belt 11 receives the cigarette and moves from the starting point along the trajectory guide groove 2 to the end point 19. The cigarette stream 17 enters the cigarette hopper storage area 14, completing the cigarette guiding work.

[0062] In this embodiment, the rotation direction and speed of the X-axis servo motor 6, the Y-axis servo motor 4, and the unwinding motor 9 are controlled by the PLC controller, thereby controlling the guide roller 1 to pull the main cigarette guide belt 11 along the path designed by the track guide groove 2, and thus orderly guiding the cigarette stream 17 to fill the entire tray loading machine hopper in a regular manner.

[0063] The descriptions of each embodiment in the above embodiments have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
