Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging equipment, in particular to a stabilizing device for the inner frame paper pattern. Background Art

[0002] In the tobacco industry, cigarette cases need to be packaged, and during the packaging process of cigarette cases, the inner frame paper needs to be transported and cut. The transportation of the inner frame paper of the ZB45 packaging machine is completed by the inner frame paper transportation and cutting mechanism. As Figure 1 shown, the inner frame paper transportation and cutting mechanism consists of two paper tray unfolding rotating shafts on the left and right, an unfolding roller 20, a pair of U-shaped dotted line cutting wheels 21, a pair of crease conveying wheels 22, and a slitting knife 23. The transportation movement of the inner frame paper tape is completed by the traction and transportation method of the crease conveying wheels 22. The two paper tray unfolding rotating shafts on the left and right have no power themselves. The unfolding of the inner frame paper 27 is clamped by the crease conveying wheels 22, and as the crease conveying wheels 22 rotate, the inner frame paper 27 is pulled out and transported by friction. The crease conveying wheels 22 are driven by a servo motor. By detecting the cursor pattern of the inner frame paper 27, the rotation angle of the servo motor is controlled to achieve the fixed-length transportation of the inner frame paper 27, and it is sent to the subsequent cutting station, where the slitting knife 23 completes the cutting of a single inner frame paper.

[0003] At the present stage, there are deficiencies in the transportation and positioning of the inner frame paper, resulting in the problem of the pattern shifting up and down. For example: Figure 2 A in Figure 2 is the correct position of the product inner frame paper pattern. Figure 2 B in

[0004] is the situation where the inner frame paper pattern often shifts during the production process. When the shift is severe, the pattern even deviates outside the inner frame paper, such as

[0005] C in

[0006] In the prior art, the pattern deviation of the inner frame paper is mainly caused by the following two aspects:

[0007] On the one hand, with the consumption of the inner frame paper tray during the production and use process, the radius of the paper tray decreases from large to small, and the pulling force required for its rotation increases, while the pulling force provided by the crease conveying wheels remains unchanged. At this time, there will be a situation of insufficient relative pulling force. Summary of the Utility Model

[0019] As described above, the inner frame paper pattern stabilizing device of the present invention has the following beneficial effects:

[0020] 1. The inner frame paper pattern stabilizing device of the present invention drives the active conveying roller through the active roller drive source to pull out the inner frame paper on the inner frame paper reel in advance and send it to a pre-stored area. The stock of the inner frame paper in the pre-storage area space is detected by the ultrasonic sensor. The rotation speed of the active roller drive source is adjusted by the control system. The active conveying roller is driven by the active roller drive source, so that the stock of the inner frame paper in the pre-storage area space is always kept within a certain range. The crease conveying wheel of the original packaging machine uses the inner frame paper in the pre-storage area space when rotating. The inner frame paper in this pre-storage area space always remains in a relaxed state without being taut. In this way, the resistance when the crease conveying wheel pulls the inner frame paper is extremely small, and the resistance does not change due to the amount of the remaining inner frame paper reel. The resistance can be kept constant, thus solving the situation in the prior art that as the radius of the inner frame paper reel becomes smaller from large, the required pulling force for rotation becomes larger, resulting in insufficient pulling force and the offset of the inner frame paper pattern; and there will be no phenomenon that the crease conveying wheel suddenly rotates and the inner frame paper slips between the crease conveying wheels, causing the inner frame paper to lag and unable to be accurately conveyed in place, resulting in the offset of the inner frame paper pattern due to lag.

[0022] 3. The present invention is a device with independent control designed without changing the original equipment. It has a simple structure and is convenient for subsequent maintenance. It solves the technical bottleneck of the unstable position of the inner frame paper pattern and has an obvious improvement effect. This device is applicable to all ZB45 packaging machine equipment.

At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of narration and are not used to limit the scope under which the present invention can be implemented. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope under which the present invention can be implemented.

[0041] Such as Figures 1 - 14As shown in the figure, the present utility model provides an inner frame paper pattern stabilizing device, which is applied to an inner frame paper conveying and cutting mechanism; the inner frame paper conveying and cutting mechanism includes a paper disk unfolding rotating shaft, a plurality of unfolding rollers 20, and a crease conveying wheel 22; the inner frame paper pattern stabilizing device includes a bottom plate 1, a plurality of guide wheel assemblies, a conveying roller assembly, and a pre-storage area guide rail assembly.

[0042] Regarding the inner frame paper pattern stabilizing device involved in the present utility model, a conveying roller assembly and a pre-storage area guide rail assembly are provided. The inner frame paper 27 is sent into the pre-storage area guide rail assembly by the conveying roller assembly. The stock of the inner frame paper 27 in the pre-storage area guide rail assembly is always kept within a certain range. When the crease conveying wheel 22 rotates, the inner frame paper 27 in the pre-storage area space is used. The inner frame paper 27 in this section of the pre-storage area space always remains in a non-tight and slack state. In this way, the resistance when the crease conveying wheel 22 pulls the inner frame paper 27 is small, and the resistance will not change due to the amount of the remaining inner frame paper disk. The resistance can be kept constant, thereby solving the problem in the prior art that the radius of the inner frame paper disk becomes smaller from large, the required pulling force for rotation becomes larger, and the pulling force is insufficient, resulting in the pattern deviation of the inner frame paper 27.

The inner frame paper 27 passes through the gap between the outer guide rail 13 and the inner guide rail 12; the ultrasonic sensor 15 is installed on the bottom plate 1 between the two inner guide rail brackets 1201, and the ultrasonic sensor 15 is communicatively connected to the control system for real-time monitoring of the remaining amount of the inner frame paper 27 between the outer guide rail 13 and the inner guide rail 12.

[0059] Further, in this embodiment, inner guide rail connection holes are provided on the inner guide rail bracket 1201, bolts are passed through the inner guide rail connection holes, and the inner guide rail 12 is installed on the inner guide rail bracket 1201 through the bolts and the inner guide rail connection holes; outer guide rail connection holes are provided on the outer guide rail bracket 1301, bolts are passed through the outer guide rail connection holes, and the outer guide rail 13 is installed on the outer guide rail bracket 1301 through the bolts and the outer guide rail connection holes.

[0060] Preferably, as Figure 12 、 Figure 13 shown, the pre-storage area guide rail assembly further includes a limit guide rail 14. The limit guide rail 14 is in an "arc" shape, and the limit guide rail 14 is installed at one end of the two outer guide rails 13 away from the conveying roller assembly. The inner peripheral surfaces of the two outer guide rails 13, the inner peripheral surface of the limit guide rail 14, and the outer peripheral surface of the inner guide rail 12 form a pre-storage area space.

[0061] In this embodiment, the ultrasonic sensor 15 is located on the midline of the "U"-shaped inner guide rail 12, and the detection range of the ultrasonic sensor 15 is 14°. It is used to monitor the remaining amount of the inner box paper 27 in the pre-storage area in real time. The ultrasonic sensor 15 feeds back the remaining amount of the inner box paper 27 in the monitored pre-storage area to the control system. The control system adjusts the rotation speed of the driving source 17 of the driving roller, thereby controlling the conveying speed of the inner box paper 27, and keeping the inner box paper 27 in the pre-storage area always in a relaxed state for driving by the crease conveying wheel 22, so as to realize the taking and using in the subsequent packaging process. Additionally, while ensuring that the inner box paper 27 in the pre-storage area is in a relaxed state, it is also necessary to ensure the accurate positioning of the inner box paper 27 in the front-back direction. Therefore, the inner guide rail connection holes and the outer guide rail connection holes are designed as long slot holes, which can adjust the positions of the inner guide rail 12 and the outer guide rail 13 in the front-back direction, so as to ensure the accurate positioning of the inner box paper 27 in the front-back direction.

[0062] Preferably, in this embodiment, the control system is an independent electric control system and is not associated with the original packaging equipment. The control system includes a controller and a push-button switch. A PLC program is set in the controller, and the controller is communicatively connected to the ultrasonic sensor 15 and the inductive sensor. The ultrasonic sensor 15 monitors the remaining amount of the inner box paper 27 in the pre-storage area in real time and sends a signal to the controller. The PLC program in the controller controls the rotation speed of the driving source 17 of the driving roller according to the signal sent by the controller. When the conveying of the inner box paper 27 is blocked during operation, the PLC program in the controller alarms to stop the driving source 17 of the driving roller, playing an overload protection role. The inductive sensor is arranged on the passive conveying roller support 11. Only after the passive conveying roller support 11 and the active conveying roller support 16 are closed and locked, the inductive sensor will send a signal, and then the controller can be started through the push-button switch.

[0063] The working steps of the inner box paper pattern stabilizing device involved in the present utility model are as follows:

[0064] S1: According to the attached Figures 3 - 12 and the descriptions of the above-mentioned various components, assemble the various components;

[0065] S2: Place the two inner box paper reels on the left paper reel unfolding rotating shaft 26 and the right paper reel unfolding rotating shaft 25 respectively. The inner box paper reel on the left paper reel unfolding rotating shaft 26 is the left inner box paper reel 24, and the inner box paper reel on the right paper reel unfolding rotating shaft 25 is the right inner box paper reel 19. The left inner box paper reel 24 and the right inner box paper reel 19 feed paper alternately. For example: first, use the left inner box paper reel 24 to feed paper, and then use the right inner box paper reel 19 to feed paper.

[0066] S3: Unfold the inner frame paper 27 on the left inner frame paper tray 24 through a number of unfolding rollers 20, and then send it into the first guiding wheel assembly 2. The first guiding wheel assembly 2 guides the inner frame paper 27 and guides the inner frame paper 27 into the conveying guide rail assembly 6. The upper guide rail 604 and the lower guide rail side plate 602 in the conveying guide rail assembly 6 position the inner frame paper 27 front and back and control the inner frame paper 27 to be fed into the conveying roller assembly at the correct position;

[0067] S4: The operator presses the upper side of the passive conveying roller support door hook 1101, the lower side of the passive conveying roller support door hook 1101 rotates, the passive conveying roller support door hook 1101 disengages from the active conveying roller support door hook 1601, and the operator lifts the passive conveying roller support 11 through the pin shaft 1103. The outer peripheral surface of the passive conveying roller 9 is separated from the outer peripheral surface of the active conveying roller 10. The operator places the inner frame paper 27 of the first guiding wheel assembly 2 on the active conveying roller 10, then resets the passive conveying roller support 11, and latches the passive conveying roller support door hook 1101 and the active conveying roller support door hook 1601;

[0068] S5: The inner frame paper 27 flowing out from the outlet of the conveying roller assembly enters the pre-storage area guide rail assembly. The inner frame paper 27 forms a U-shaped turn between the inner guide rail 12 and the outer guide rail 13, then flows out from the pre-storage area guide rail assembly, passes through the second guiding assembly and enters the U-shaped dotted line cutting wheel 21, then enters the crease conveying wheel 22 from the U-shaped dotted line cutting wheel 21, and then undergoes subsequent cutting processes from the crease conveying wheel 22;

[0069] S6: After the inner frame paper 27 undergoes the operations in steps S2 - S5, the initial position setting of the inner frame paper 27 is completed. At this time, the passive conveying roller support door hook 1101 and the active conveying roller support door hook 1601 are latched, and the inductive sensor sends a signal to the control system. The operator starts the crease conveying wheel 22. The crease conveying wheel 22 pulls the inner frame paper 27 from the pre-storage area space. The inner frame paper 27 in the pre-storage area space is pulled, and the remaining amount of the inner frame paper 27 decreases. The ultrasonic sensor 15 monitors the remaining amount of the inner frame paper 27 in real time. The control system starts and adjusts the rotation speed of the active roller drive source 17. The active conveying roller 10 pulls the inner frame paper 27 from the left inner frame paper tray 24 and sends the inner frame paper 27 into the pre-storage area space, so that the inner frame paper 27 in the pre-storage area space is always in a relaxed state for subsequent pulling by the crease conveying wheel 22.

[0070] Preferably, as shown in the figure, in step S5, the inner box paper 27 is conveyed to the right by the conveying roller assembly, makes a U-turn between the inner guide rail 12 and the outer guide rail 13, and then is turned by the second guide wheel assembly 5 and is pulled and conveyed to the right by the crease conveying wheel 22. When the crease conveying wheel 22 rotates, the inner box paper 27 in the pre-storage area space will be consumed, and the U-turn will move to the left. At this time, the conveying speed of the conveying roller assembly will be increased to feed the paper into the pre-storage area space faster; when the operating speed of the crease conveying wheel 22 decreases, the consumption speed of the inner box paper in the pre-storage area space decreases, and the U-turn will move to the right, and the conveying roller assembly will reduce the speed or stop rotating to ensure that the stock of the inner box paper 27 in the pre-storage area space always remains within a certain range. In this way, it can be ensured that the inner box paper 27 in the pre-storage area space always remains in a relaxed state, minimizing and equalizing the resistance received by the crease conveying wheel 22 when conveying the inner box paper 27, thereby improving the conveying stability.

[0071] Preferably, when the inner box paper 27 on the left inner box paper reel 24 is used up, it is necessary to replace the inner box paper 27 on the right inner box paper reel 19. The operator pulls the crease conveying wheel 22. At this time, there is enough remaining amount of the inner box paper 27 in the pre-storage area space, and the ultrasonic sensor 15 feeds back a control signal to the control system, and the control system controls the active conveying roller 10 to stop working. The operator pulls the tail of the inner box paper 27 on the left inner box paper reel 24 onto the conveying guide rail assembly 6, rotates the cutting knife 7, and the cutting knife 7 fits with the fixed knife 18 to cut the tail of the inner box paper 27 on the left inner box paper reel 24 on the conveying guide rail assembly 6 to form a regular notch; the head of the inner box paper 27 on the right inner box paper reel 19 is sent onto the conveying guide rail assembly 6 through the third guide wheel assembly 4 and the first guide wheel assembly 2, rotates the cutting knife 7, and the cutting knife 7 fits with the fixed knife 18 to cut the head of the inner box paper 27 on the right inner box paper reel 19 on the conveying guide rail assembly 6 to form a regular notch, aligns the regular notch at the tail of the inner box paper 27 with the regular notch at the head of the inner box paper 27 and connects them with tape, and then starts the crease conveying wheel 22 again to realize the continuous conveying of the inner box paper 27.

[0072] In addition, the inner box paper pattern stabilizing device involved in the present invention is mainly used when producing commodities with patterns on the inner box paper 27. When producing products without patterns on the inner box paper 27, normal production can be carried out according to the original packaging equipment, reducing the use wear of the inner box paper pattern stabilizing device.

[0073] The inner frame paper pattern stabilizing device of the present utility model has adjustable positions of the lower guide rail side plate 602 and the lower guide rail middle plate 603 on the conveying guide rail assembly 6 on the guide rail base 601 to adapt to the sizes of different specifications of the inner frame paper 27 and production requirements; the present utility model eliminates the quality defect of the pattern offset of the inner frame paper 27 and significantly improves the stability of the product quality; without changing the original equipment, the inner frame paper pattern stabilizing device in this application adopts independent control, has a simple structure and is convenient for subsequent maintenance, solves the technical bottleneck of the unstable pattern position of the inner frame paper 27, and has an obvious improvement effect.

[0074] In summary, the present utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
