[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present application or its application or use.

[0033] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0034] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of exemplary embodiments may have different values.

[0035] The present application provides an automatic replacement system for transparent paper in cigarette boxes of a cigarette packaging machine, which realizes automatic installation of transparent paper in cigarette boxes through an axial feeding component and a circumferential positioning component, and realizes replacement of new and old transparent paper in cigarette boxes through automatic splicing components. The automated replacement system greatly reduces labor intensity and improves equipment operation efficiency and product quality.

[0036] The automatic replacement system of transparent paper for strip boxes of a cigarette packaging machine comprises a PLC controller, an automatic installation component and an automatic splicing component. The PLC controller is respectively connected with detectors and actuator signals in the automatic installation component and the automatic splicing component.

[0037] As an example, Figure 1-3 As shown, the automatic installation component includes two positioning members (a first positioning member 10 and a second positioning member 20 with the same height) spaced apart on the first side wall 1 of the frame of the cigarette packaging machine, an axial feeding assembly and a circumferential fixing assembly.

[0038] In this embodiment, two strips of transparent paper are positioned on the axial feeding assembly, and the central axes of the two strips of transparent paper (i.e., the central axes of the central paper circles 25 and 27 of the strips of transparent paper, see Figure 3 ) are respectively colinear with the central axis of the corresponding positioning piece, the axial feeding component passes the strip box transparent paper on the positioning piece along the axial direction of the positioning piece, and the circumferential fixing component fixes the strip box transparent paper on the positioning piece.

[0039] Specifically, the axial feeding assembly includes an axial driver, an axial feeding member, a first two-position four-way electromagnetic reversing valve and two first magnetic induction switches.

[0040] As an example, Figure 2 As shown, the axial drive is the first cylinder 23 (mechanical contact type rodless cylinder). Figure 1-3 As shown, the axial feed member 12 is arranged below the two positioning members. The central axis of the output shaft of the axial driver is parallel to the central axis of the positioning member, and the output shaft of the first cylinder 23 is fixedly connected to the axial feed member 12. During the automatic feeding process, the first box of transparent paper 24 to be installed on the first positioning member 10 and the second box of transparent paper 26 to be installed on the second positioning member 20 are positioned on the axial feed member 12.

[0041] As an embodiment, a support platform 13 is provided on the bottom plate 29 of the frame, and a guide rod 28 ( Figure 2 The axial feed member 12 is slidably connected to the guide rod 28 (shown as 2).

[0042] Specifically, the first cylinder 23 is fixedly installed on the support platform 13. A notch is axially provided on the cylinder tube of the first cylinder 23. Sliders are symmetrically fixed on both sides of the piston rod of the first cylinder 23. After passing through the notch, the sliders are fixedly connected to the axial feed member 12 together.

[0043] The first two-position four-way electromagnetic directional control valve is used to control the axial feed and retraction of the first cylinder 23. Two first magnetic induction switches B_Feeder_Cylinder_Base and B_Feeder_Cylinder_Work are respectively installed at the base position and the working position on the outer wall of the cylinder body of the first cylinder 23, serving as the base position magnetic induction switch and the working position magnetic induction switch of the first cylinder 23 respectively, for detecting whether the first cylinder 23 returns to the base position and the working position.

[0044] Preferably, the automatic installation component further includes a lifting assembly. In this embodiment, there is a certain height difference between the support platform 13 and the axial feed member 12 and the positioning member. The lifting assembly includes two carriers with the same structure (the first carrier 11 and the second carrier 21), two lifting drivers fixed on the bottom plate 29 of the frame, two middle "O"-type three-position four-way electromagnetic directional control valves, two travel switches, and 4 second magnetic induction switches.

[0045] As an embodiment, as Figure 1 shown, the two lifting drivers are respectively the second cylinder 14 and the third cylinder 22. The two carriers 11 and 21 are respectively slidably arranged on the upper end surface of the axial feed member 12 in the vertical direction. During the automatic installation process, the two strip box transparent papers 24 and 26 (please refer to Figure 3 ) are respectively positioned on the corresponding carriers 11 and 21. The output shafts of the second cylinder 14 and the third cylinder 22 respectively pass through the axial feed member 12 and are fixedly connected to the corresponding carriers 11 and 21. Travel switches are respectively provided on the carriers 11 and 21.

[0046] As an embodiment, as Figure 4 and 5 shown, the top surface 111 of the main body 115 of the first carrier 11 is in an arc shape that fits the outer circumferential surface of the strip box transparent paper. Please combine Figure 2 , two corner parts on the side of the first carrier 11 away from the positioning member are respectively provided with upward protruding baffles 112 and 113. When the strip box transparent paper is placed on the carrier, the end of the strip box transparent paper always abuts against the baffle, preventing the strip box transparent paper from axially moving during the axial feed of the carrier and causing the situation that the strip box transparent paper is not properly installed and fixed on the positioning member.

[0047] Four corner portions of the bottom surface of the body 115 of the first carrier 11 are respectively provided with long pin-shaped guide rails 116. Corresponding positions on the axial feed member 12 are provided with vertical guide holes. The long pin-shaped guide rails 116 are inserted into the guide holes, and the two are in clearance fit, which plays a guiding role in lifting the first carrier, enhances its stability, and after the second cylinder 14 and the third cylinder 22 reach their maximum strokes, the long pin-shaped guide rails 116 still will not break away from the guide holes, preventing the first carrier and the strip box transparent paper from tipping over, falling off or axially moving during axial feeding.

[0048] Preferably, a notch 114 extending along the axis of the positioning member is provided in the middle of the first carrier 11, which is convenient for reducing the weight of the carrier and ensuring the working stability of the lifting driver.

[0049] Two "O"-type three-position four-way electromagnetic directional control valves are respectively used to control the extension and retraction of the second cylinder 14 and the third cylinder 22. The "O"-type three-position four-way electromagnetic directional control valve can ensure that when the power is cut off due to external factors during the lifting of the carrier, the second cylinder 14 and the third cylinder 22 will not lose air, preventing accidents such as the strip box transparent paper being damaged by impact or the strip box transparent paper falling to the ground and being damaged. Two travel switches B_First_Material_at_position and B_Second_Material_at_position are respectively installed on the first carrier 11 and the second carrier 21, and are respectively used to detect whether the strip box transparent paper is placed on the first carrier 11 and the second carrier 21. Among them, two second magnetic induction switches B_First_Lift_Cylinder_Base and B_First_Lift_Cylinder_Work are respectively installed on the basic position and the working position of the outer wall of the cylinder body of the second cylinder 14, serving as the basic position magnetic induction switch and the working position magnetic induction switch of the second cylinder 14, and are respectively used to detect whether the second cylinder 14 returns to the basic position and the working position. Additionally, two second magnetic induction switches B_Second_Lift_Cylinder_Base and B_Second_Lift_Cylinder_Work are respectively installed on the basic position and the working position of the outer wall of the cylinder body of the third cylinder 22, serving as the basic position magnetic induction switch and the working position magnetic induction switch of the third cylinder 22, and are respectively used to detect whether the third cylinder 22 returns to the basic position and the working position.

[0050] When the first shift is in production, two boxes of transparent paper need to be installed at the same time. The two boxes of transparent paper are placed on the first carrier 11 and the second carrier 21 respectively. Under the action of gravity, the two boxes of transparent paper press down the travel switches on the first carrier 11 and the second carrier 21. Both the travel switches B_First_Material_at_position and B_Second_Material_at_position have signals. After receiving the signal, the PLC controller outputs a high-level signal, so that the coil K1 of the "O" type three-position four-way electromagnetic reversing valve in the second cylinder 14 and the third cylinder 22 The coil K2 of the middle "O" type three-position four-way solenoid reversing valve is energized at the same time, the two middle "O" type three-position four-way solenoid reversing valves are switched, the air path is changed, and the second cylinder 14 and the third cylinder 22 are controlled to extend at the same time. When the carrier together with the strip box transparent paper rises to the same height as the positioning parts 10 and 20, the second cylinder 14 and the third cylinder 22 also reach their maximum stroke. At this time, the working position magnetic induction switches B_First_Lift_Cylinder_Work and B_Second_Lift_Cylinder_Work of the second cylinder 14 and the third cylinder 22 both have signals, that is, the lifting of the strip box transparent paper is completed. After receiving the signals of B_First_Lift_Cylinder_Work and B_Second_Lift_Cylinder_Work, the PLC controller outputs a high-level signal, which energizes the coil K3 of the first two-position four-way solenoid reversing valve of the first cylinder 23. The first two-position four-way solenoid reversing valve is reversed, and the air path is changed to control the axial feeding of the first cylinder 23. When the first cylinder 23 is fed into place, its magnetic induction switch B_Feeder_Cylinder_Work has a signal, indicating that the center paper circle of the transparent paper in the strip box has been installed on the positioning piece.

[0051] As an embodiment, the circumferential fixing component includes a first positioning member 10, a second positioning member 20, two second two-position four-way electromagnetic directional control valves, and four third magnetic induction switches. Both the first positioning member 10 and the second positioning member 20 adopt three-jaw fixed cylinders. The two second two-position four-way electromagnetic directional control valves are respectively used to control the extension and retraction of the first positioning member 10 and the second positioning member 20. Among them, the two third magnetic induction switches B_First_Fixed_Cylinder_Base and B_First_Fixed_Cylinde_Work serve as the basic position magnetic induction switch and the working position magnetic induction switch of the first positioning member 10 respectively, and are used to detect whether the first positioning member 10 returns to the basic position and the working position. The other two third magnetic induction switches B_Second_Fixed_Cylinder_Base and B_Second_Fixed_Cylinde_Work serve as the basic position magnetic induction switch and the working position magnetic induction switch of the second positioning member 20 respectively, and are used to detect whether the second positioning member 20 returns to the basic position and the working position.

[0052] After the axial feeding of the strip box transparent paper is in place, the magnetic induction switch B_Feeder_Cylinder_Work at the working position of the first cylinder 23 has a signal. After receiving this signal, the PLC controller outputs a high-level signal. This high-level signal causes the coils K4 and K5 of the second two-position four-way electromagnetic reversing valves of the first positioning member 10 and the second positioning member 20 to be energized respectively. These two second two-position four-way electromagnetic reversing valves reverse respectively, the gas path changes, and it controls the first positioning member 10 and the second positioning member 20 to extend. The three-jaw cylinder is tightened on the inner wall of the paper ring of the strip box transparent paper to realize the circumferential fixation of the strip box transparent paper. At this time, the magnetic induction switches B_First_Fixed_Cylinde_Work and B_Feeder_Cylinder_Work at the working positions of the second cylinder 14 and the third cylinder 22 both have signals. After receiving this signal, the PLC controller outputs a high-level signal. This high-level signal causes the coil K3 of the first two-position four-way electromagnetic reversing valve of the first cylinder 23 to lose power. This first two-position four-way electromagnetic reversing valve reverses again, the gas path changes again, and it controls the first cylinder 23 to retract to the basic position. After the first cylinder 23 retracts to the basic position, both of the two travel switches B_First_Material_at_position and B_Second_Material_at_position lose signals, indicating that the strip box transparent paper on the carrier has been taken away and placed on the positioning member. At the same time, the magnetic induction switch B_Feeder_Cylinder_Base at the basic position of the first cylinder 23 has a signal. After receiving this signal, the PLC controller outputs a high-level signal. This high-level signal causes the coils K1 of the middle "O"-type three-position four-way electromagnetic reversing valve of the second cylinder 14 and the coils K2 of the middle "O"-type three-position four-way electromagnetic reversing valve of the third cylinder 22 to lose power simultaneously. These two middle "O"-type three-position four-way electromagnetic reversing valves reverse again, the gas path changes again, and it controls the second cylinder 14 and the third cylinder 22 to retract to the basic position. When the second cylinder 14 and the third cylinder 22 retract to the basic position, the magnetic induction switches B_First_Lift_Cylinder_Base and B_Second_Lift_Cylinder_Base at the basic positions of the second cylinder 14 and the third cylinder 22 have signals. At this time, the installation of the strip box transparent paper is completed.

[0053] It should be noted that the automatic installation component can also install only the first strip box transparent paper or the second strip box transparent paper separately on the corresponding positioning member.

[0054] As an embodiment, the automatic splicing component includes an automatic ironing component and an automatic cutting component.

[0055] Such as Figure 1-3As shown in the figure, the automatic ironing assembly is arranged above the automatic installation component. The automatic ironing assembly includes a suction platform 17, an adhesion platform 7, a soldering iron 6, a soldering iron driver, a third two-position four-way electromagnetic directional valve, a two-position two-way electromagnetic directional valve, a photoelectric switch, and two fourth magnetic induction switches.

[0056] As Figure 1 and 6 As shown in the figure, a plurality of air suction holes 16 are provided on the suction platform 17. The suction platform 17 is fixed on the first side wall 1. The suction platform 17 is arranged between the adhesion platform 7 and the second positioning member 20. The suction platform 17 is located directly above the first positioning member 10. The suction platform 17 sucks the second strip box transparent paper 26 on the second positioning member 20.

[0057] The adhesion platform 7 is fixed on the first side wall 1. The adhesion platform 7 is arranged obliquely above the first positioning member 10 on the side away from the second positioning member 20. The adhesion platform 7 is arranged on the movement path of the first strip box transparent paper 24 on the first positioning member 10 (without passing through the suction platform 17).

[0058] As Figure 1-3 As shown in the figure, a swing rod frame is arranged between the opposite first side wall 1 and the second side wall. The two swing rod arms 5 of the swing rod frame are fixedly connected to the bottom plate 29. The upper ends of the two swing rod arms 5 are rotatably installed with upper and lower parallel swing rod guide columns 3 through swing rod sleeves 4.

[0059] Specifically, as Figure 3 shown in the figure, the first strip box transparent paper 24 first passes through the adhesion platform 7, then bypasses the lower swing rod guide column 3 and then winds around the lowermost transparent paper guide rod 15 on the first side wall 1, and then bypasses the upper swing rod guide column 3, and then sequentially bypasses the two transparent paper guide rods 15 on the first side wall 1 upward and then extends downstream.

[0060] The soldering iron 6 is located above the adhesion platform 7. As an embodiment, the soldering iron driver is a fourth cylinder 2, which is located above the soldering iron 6 and fixed on the first side wall 1. The piston rod end of the fourth cylinder 2 is fixedly connected to the soldering iron 6. The soldering iron 6 will be powered on all the time after startup and continuously maintain a certain set temperature.

[0061] During the automatic splicing process, the head of the second strip box transparent paper 26 is located on the adhesion platform 7, and the fourth cylinder 2 drives the soldering iron 6 to move to the adhesion platform 7 for ironing.

[0062] The photoelectric switch B_Run_Out_min is arranged on the second side wall of the frame (not shown in the figure) for detecting the minimum remaining amount of the first strip box transparent paper 24. Among them, the second side wall is opposite to the first side wall. There is a preset distance (such as 2 mm) between the photoelectric switch and the outer diameter of the central paper coil of the strip box transparent paper.

[0063] Understandably, the present application can also be provided with a photoelectric switch for detecting the minimum remaining amount of the second strip of cellophane 26.

[0064] The third two-position four-way electromagnetic reversing valve is used to control the extension and retraction of the fourth cylinder 2, and the two-position two-way electromagnetic reversing valve is used to control the on-off of the air suction on the adsorption platform 17. Two fourth magnetic induction switches B_iron_Cylinder_Base and B_iron_Cylinder_Work are respectively installed at the basic position and the working position on the outer wall of the cylinder body of the fourth cylinder 2, and serve as the basic position magnetic induction switch and the working position magnetic induction switch of the fourth cylinder 2, respectively, for detecting whether the fourth cylinder 2 returns to the basic position and the working position.

[0065] After the strip of cellophane is installed on the positioning member, the cigarette packing machine is powered on and started. After powering on and starting, the coil K8 of the two-position two-way electromagnetic reversing valve of the adsorption platform 17 is energized, the two-position two-way electromagnetic reversing valve changes direction, and the air suction is turned on. The second strip of cellophane 26 needs to be manually placed on the adsorption platform 17, and the coil K8 remains energized all the time, so that the second strip of cellophane 26 is always adsorbed on the adsorption platform 17. When the first strip of cellophane 24 is about to be exhausted and reaches the minimum remaining amount, the photoelectric switch B_Run_Out_min loses the signal. After receiving this signal, the PLC controller outputs a high-level signal. This high-level signal controls the cigarette packing machine to stop. At the same time, this high-level signal controls the coil K6 of the third two-position four-way electromagnetic reversing valve of the fourth cylinder 2 to be energized. This third two-position four-way electromagnetic reversing valve changes direction, the gas path changes, and it controls the fourth cylinder 2 to vertically press on the overlapping part of the first strip of cellophane 24 passing through the adhesion platform 7 and the second strip of cellophane 26 placed on the adhesion platform 7. Under the action of high temperature, the first strip of cellophane and the second strip of cellophane are spliced together. At this time, the working position magnetic induction switch B_iron_Cylinder_Work of the fourth cylinder 2 has a signal. After receiving this signal, the PLC controller starts timing. After the electric soldering iron 6 irons on the adhesion platform 7 for a preset time (such as 1 s), the PLC controller controls the automatic cutting assembly to cut off the first strip of cellophane 24.

[0066] As Figure 1-3 shown, the automatic cutting assembly includes a cutting rack 8, a rack clamp 9, a clamp driver, a fourth two-position four-way electromagnetic reversing valve, and two fifth magnetic induction switches. The clamp driver is fixed on the first side wall 1 of the frame and can slide relatively along the side of the adhesion platform 7. The rack clamp 9 is fixedly connected to the output shaft of the clamp driver, and the cutting rack 8 is installed on the rack clamp 9.

[0067] As an embodiment, the clamp driver is a fifth cylinder 19.

[0068] The fourth two-position four-way electromagnetic directional control valve is used to control the extension and retraction of the fifth cylinder 19. Two fifth magnetic induction switches B_Cut_Cylinder_Base and B_Cut_Cylinder_Work are respectively installed at the basic position and the working position on the outer wall of the cylinder body of the fifth cylinder 19, serving as the basic position magnetic induction switch and the working position magnetic induction switch of the fifth cylinder 19, and are used to detect whether the fifth cylinder 19 returns to the basic position and the working position.

[0069] When the working position magnetic induction switch B_iron_Cylinder_Work of the fourth cylinder 2 has a signal and after a preset time delay, the PLC controller outputs a high-level signal. This high signal controls the coil K7 of the fourth two-position four-way electromagnetic directional control valve of the fifth cylinder to be energized, and the fourth two-position four-way electromagnetic directional control valve changes its direction, the gas path changes, and controls the fifth cylinder 19 to extend, so that the cutting rack 8 presses against the tensioned first strip of carton transparent paper 24 and cuts it at the tail of the first strip of carton transparent paper 24. At this time, the working position magnetic induction switch B_Cut_Cylinder_Work of the fifth cylinder 19 has a signal. After the PLC receives this signal, it outputs a low-level signal, causing the coil K6 of the third two-position four-way electromagnetic directional control valve of the fourth cylinder 2 to lose power, and the third two-position four-way electromagnetic directional control valve changes its direction again, the gas path changes again, and controls the fourth cylinder 2 to retract. When the fourth cylinder 2 retracts to the basic position, the basic position magnetic induction switch B_iron_Cylinder_Work of the fourth cylinder 2 has a signal. After the PLC receives this signal, it outputs a low-level signal. This low-level signal causes the coil K7 of the fourth two-position four-way electromagnetic directional control valve of the fifth cylinder 19 to lose power, and the fourth two-position four-way electromagnetic directional control valve changes its direction again, the gas path changes again, and controls the fifth cylinder 19 to retract to the basic position. When the fifth cylinder 19 retracts to the basic position, the basic position magnetic induction switch B_Cut_Cylinder_Base of the fifth cylinder 19 has a signal. After the PLC receives this signal, it outputs a low-level signal. This low-level signal causes the coil K8 of the two-position two-way electromagnetic directional control valve of the adsorption platform 17 to lose power, the two-position two-way electromagnetic directional control valve changes its direction and closes the air suction, the second strip of carton transparent paper 26 is released, and controls the cigarette packing machine to restart. The strip package with the splicing joint is detected manually. Thus, the automatic splicing of the carton transparent paper is completed, and the automatic replacement of the entire carton transparent paper is completed.

[0070] It should be noted that the automatic splicing component may also include an automatic cutting component for cutting the second strip of carton transparent paper, which has a similar structure and the same principle as the automatic cutting component of the first strip of carton transparent paper, and will not be elaborated here.

[0071] Although some specific embodiments of the present application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
