Deviation correction conveying device

Abstract

According to the technical scheme, a detection component is arranged on a conveying channel formed between an upper conveying mechanism and a lower conveying mechanism in a matched mode, and after the detection component detects the deviation state of materials, a servo mechanism adjusts the running speed of an upper servo motor and the running speed of a lower servo motor through a controller. Meanwhile, a pressure adjusting mechanism is further included, and the pressure adjusting mechanism dynamically adjusts vertical pressing force formed between the upper conveying belt and the lower conveying belt on the materials in the process, so that the friction force borne by the materials is further changed; due to the arrangement of the pressure adjusting mechanism, the speed difference is not used as a unique control variable any more, the deviation rectifying effect is enhanced by further influencing the actual effect of friction force, and the deviation rectifying device has the advantage of being stable in deviation rectifying effect.

Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper conveying equipment, and in particular to a correction and transmission device. Background Technology

[0002] Corrugated paper conveying is a crucial component of automated packaging production lines, and its alignment accuracy directly impacts the quality of die-cutting, printing, and stacking. With increasing demands for high-speed production, traditional contact-based alignment technologies (such as baffle limiting and roller pushing) are no longer adequate due to their tendency to scratch the paper surface and slow response. Therefore, non-contact differential alignment technology has become the mainstream direction for industry upgrades.

[0003] Currently, this technology is mainly divided into two categories in practical applications. The first is local station differential speed correction, which involves adding an accelerating belt at specific processing positions (such as bending and joining areas) to temporarily correct material misalignment by using a higher speed in the latter section than in the former. The second is dual-belt global differential speed correction, which utilizes the speed difference between the upper and lower conveyor belts (e.g., left faster than right) to cause the corrugated paper sandwiched in the middle to slide laterally and gradually return to its correct position. Differential speed correction technology relies on the lateral friction force generated by the speed difference to drive the cardboard back to its correct position. However, the actual effect of this friction force is affected by multiple factors (such as thickness or humidity). Thick cardboard requires more friction force to pull, but it is prone to slippage when the speed is increased, while excessive friction on thin cardboard can lead to surface crushing. When the cardboard is damp and slippery, the amount of sliding is insufficient under the same speed difference, while excessive displacement may occur when it is dry and rough. In high-speed continuous production, the correction effect is unstable under the same speed difference setting, forcing the equipment to run at a reduced speed or frequently stop for adjustment, resulting in overall transportation instability.

[0004] In summary, existing differential speed correction technology treats speed difference as the only control variable, while neglecting the control of the actual effect of correction friction. This leads to unstable correction effect under different working conditions, ultimately resulting in insufficient reliability in the material transportation process. Existing technology has the technical defect of unstable correction effect. Utility Model Content

[0005] The main purpose of this invention is to propose a correction transmission device, which aims to solve the technical problem of unstable correction effect in the existing technology.

[0006] To achieve the above objectives, this utility model proposes a correction transmission device, comprising:

[0007] The upper conveyor mechanism includes the upper conveyor belt;

[0008] The lower conveyor mechanism includes a lower conveyor belt, which is arranged opposite to the upper conveyor mechanism, and a conveying channel for conveying materials is formed between the upper and lower conveyor belts.

[0009] The detection component is installed at the beginning of the transmission channel to detect the offset of the material in the transmission channel.

[0010] The servo mechanism includes an upper servo motor, a lower servo motor, and a controller. The upper and lower servo motors are respectively connected to the upper and lower conveying mechanisms. The controller is connected to the detection component. Simultaneously, based on the detected material offset, the controller creates a speed difference between the upper and lower servo motors, driving the material to move laterally.

[0011] The pressure regulating mechanism is used to dynamically adjust the vertical clamping force exerted on the material between the upper and lower conveyor belts.

[0012] Furthermore, a pressure regulating mechanism is provided on the upper conveying mechanism and is used to move the upper conveying mechanism in the vertical direction.

[0013] Furthermore, the pressure regulating mechanism includes a drive unit, a transmission unit, and a connecting assembly. The drive unit and the transmission unit are connected by a transmission connection. The connecting assembly includes a first connecting plate and a second connecting plate. The first connecting plate is movably connected to the second connecting plate and can move relative to the second connecting plate. The drive unit is fixedly connected to the first connecting plate, and the transmission unit is fixedly connected to the second connecting plate. At the same time, the upper transmission mechanism is fixedly connected to the second connecting plate.

[0014] Furthermore, the first connecting plate has a slide rail on its side, and the first connecting plate is slidably connected to the second connecting plate through the slide rail.

[0015] Furthermore, the slide rail includes a slider and a track. The slider can slide up and down along the track. At the same time, the slider is fixed to the first connecting plate, and the track is fixed to the second connecting plate.

[0016] Furthermore, the lower conveyor mechanism is fixedly connected to the third connecting plate, and at the same time, the lower conveyor mechanism is fixedly connected to the suction box through the third connecting plate.

[0017] Furthermore, the suction box includes a box body and a fan. The top of the box body has an opening and a side wall. The fan is located at the opening on the top of the box body. The bottom surface of the lower conveyor belt in the transmission channel section is located on the top of the box body. At the same time, the lateral edge of the lower conveyor belt in the transmission channel section abuts against the side wall.

[0018] Furthermore, the upper conveying mechanism is equipped with guide wheels to assist the upper conveyor belt in transmission.

[0019] Furthermore, the guide wheel includes an inner ring portion, an outer ring portion, and a cylindrical surface. The inner ring portion and the outer ring portion are located at both ends of the cylindrical surface, and the top surface of the upper conveyor belt in the transmission channel portion abuts against the cylindrical surface. At the same time, the two side edges of the upper conveyor belt in the transmission channel portion abut against the inner ring portion and the outer ring portion, respectively.

[0020] Furthermore, the detection component employs a photoelectric sensor.

[0021] This invention features a detection component in the transmission channel formed between the upper and lower conveyor mechanisms. After the detection component detects the material's deviation, the servo mechanism adjusts the operating speeds of the upper and lower servo motors via a controller, creating a speed difference. This speed difference generates friction, driving the material to move laterally and reset. The invention also includes a pressure adjustment mechanism that dynamically adjusts the vertical pressure exerted on the material by the upper and lower conveyor belts during the process, further altering the friction force on the material. Because of the pressure adjustment mechanism, this invention no longer uses the speed difference as the sole control variable, but enhances the correction effect by further influencing the actual friction force. Therefore, this invention offers the advantage of a more stable correction effect. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0036] This utility model proposes a correction transmission device.

[0037] In this embodiment of the utility model, such as Figures 1 to 9As shown, the correction and conveying device includes an upper conveying mechanism 1 and a lower conveying mechanism 2 arranged opposite to each other. The upper conveying mechanism 1 includes an upper conveyor belt 11, and the lower conveying mechanism 2 includes a lower conveyor belt 21. A conveying channel 3 for conveying materials is formed between the upper conveyor belt 11 and the lower conveyor belt 21. Please refer to the attached diagram. Figures 1 to 2 The diagram shows that the upper conveyor belt 11 operates via the upper driving wheel 12 and the upper driven wheel 13, while the lower conveyor belt 21 operates via the lower driving wheel 22 and the lower driven wheel 23. It also includes a detection component (not shown), installed at the starting point of the transmission channel 3 to detect the offset state of the material within the channel. Furthermore, it includes a servo mechanism 4, comprising an upper servo motor 41, a lower servo motor 42, and a controller (not shown). The upper servo motor 41 and the lower servo motor 42 are respectively connected to the upper conveyor mechanism 1 and the lower conveyor mechanism 2. Specifically, the upper servo motor 41 and the lower servo motor 42 are respectively connected to the upper driving wheel 12 and the lower driving wheel 22, thereby controlling the operation of the upper conveyor belt 11 and the lower conveyor belt 21. The controller is connected to the detection component, and based on the detected offset state of the material, the controller adjusts the upper servo motor 41 and the lower servo motor 23 accordingly. The lower servo motor 42 creates a speed difference, driving the material to move laterally. It can be understood that the aforementioned technical content mainly corresponds to the prior art, achieving differential speed correction through the speed difference between the upper conveyor belt 11 and the lower conveyor belt 21. In order to further enhance the correction stability, this utility model also includes a pressure adjustment mechanism 5. The pressure adjustment mechanism 5 is used to dynamically adjust the vertical clamping force formed between the upper conveyor belt 11 and the lower conveyor belt 21 on the material. By adding the pressure adjustment mechanism 5, this utility model makes the differential speed correction scheme not limited to the speed difference as a single factor. The pressure adjustment mechanism 5 can increase the pressure on the material in the vertical direction by adjusting the clamping force generated by the upper conveyor belt 11 and the lower conveyor belt 21 on the material, thereby changing the friction force that drives the material to move laterally, thereby increasing the correction stability. It can also adapt to specific situations (typically, materials of different thicknesses).

[0038] It should be noted beforehand that the materials referred to in this utility model should be understood as corrugated paper-related materials, such as cardboard, paper boxes, color boxes, and color cartons. It can be understood that this utility model can be applied to box gluing machines, carton gluing machines, double-sheet carton gluing machines, and nail gluing machines based on its working principle. As for how to install this utility model in the aforementioned mechanical equipment, it is not within the scope of this utility model discussion. Adaptive installation can be carried out according to the actual situation.

[0039] Additionally, it should be noted that the upper conveyor belt 11 and lower conveyor belt 21 described in this utility model are mainly understood as belts. Belt conveying (such as rubber, PVC, PU, ​​etc.) is very mainstream in corrugated cardboard transportation, especially in applications with medium to light loads, long straight distances, and cost sensitivity. This utility model is also mainly used in medium to light load scenarios. Therefore, when other conventional structures such as chain plates, rollers, modules, and mesh belts are substituted into the upper conveyor belt 11 and lower conveyor belt 21, some adaptive adjustments can be made to this utility model to better achieve the final effect. The relevant content will not be elaborated here, only the situation is explained.

[0040] Understandably, the concept of this utility model is to add a pressure regulating mechanism 5 to form a vertical clamping force on the material in the transmission channel 3. It is more in line with operating habits and mechanical common sense to form pressure from above the transmission channel 3. In some embodiments of this utility model, the pressure regulating mechanism 5 is provided on the upper transmission mechanism 1 and is used to move the upper transmission mechanism 1 in the vertical direction.

[0041] Specifically, the pressure regulating mechanism 5 includes a drive unit 51, a transmission unit 52, and a connecting assembly 53. The drive unit 51 and the transmission unit 52 are connected by a transmission mechanism. The drive unit 51 can be configured according to the attached... Figure 1 To be continued Figure 5 The content shown is a motor. Of course, it can also be replaced by a conventional method using a combination of a cylinder or a motor and a mechanical structure (typically a combination of a lead screw and a rotary motor) according to actual objective conditions. The connecting component 53 includes a first connecting plate 531 and a second connecting plate 532. The first connecting plate 531 is movably connected to the second connecting plate 532. The first connecting plate 531 can move relative to the second connecting plate 532. The driving part 51 is fixed to the first connecting plate 531, and the transmission part 52 is fixed to the second connecting plate 532. At the same time, the upper conveying mechanism 1 is fixed to the second connecting plate 532. In the process of adjusting the upper conveyor belt 11, the driving part 51 acts on the transmission part 52, and then affects the pressure of the upper conveyor belt 11 through the second connecting plate 532.

[0042] Specifically, from the perspective of simplicity and operability, a movable connection method for the first connecting plate 531 and the second connecting plate 532 is proposed. A slide rail 6 is provided on the side of the first connecting plate 531, and the first connecting plate 531 is slidably connected to the second connecting plate 532 through the slide rail 6.

[0043] More specifically, the slide rail 6 includes a slider 61 and a track 62. The slider 61 can slide up and down along the track 62. At the same time, the slider 61 is fixed to the first connecting plate 531, and the track 62 is fixed to the second connecting plate 532. The slide rail 6 is provided on both sides of the first connecting plate 531 through the aforementioned specific structure. Based on the movable connection, since the slider 61 is restricted to slide on the track 62, the slide rail 6 can achieve a stable movement state by setting the orientation of the track 62. At the same time, the range of motion can be controlled by setting the area of ​​the track 62.

[0044] It is foreseeable that the upper conveyor belt 11 and lower conveyor belt 21 corresponding to the transmission channel 3 may not be in close contact with the material, which will affect the material conveying effect to a certain extent. In some embodiments of this utility model, the lower conveying mechanism 2 is fixedly connected to the third connecting plate 7. At the same time, the lower conveying mechanism 2 is fixedly connected to the suction box 8 through the third connecting plate 7. Under the action of the air force brought by the suction box 8, the material will be in close contact with the lower conveyor belt 21, so as to avoid abnormal displacement.

[0045] Specifically, the suction box 8 includes a box body 81 and a fan 82. The box body 81 has an opening 811 at the top and a side wall 812. The fan 82 is located at the opening 811 at the top of the box body 81. It should be noted that in order to enhance the stability of the lower conveyor belt 21, the lower conveyor belt 21 is limited here. Specifically, the connection relationship is as follows: the bottom surface of the lower conveyor belt 21 in the transmission channel 3 is located on the top of the box body 81. At the same time, the lateral edge of the lower conveyor belt 21 in the transmission channel 3 abuts against the side wall 812. It can be understood that in this local position, the lower conveyor belt 21 is limited by at least the top of the box body 81 and the side wall 812.

[0046] In some embodiments of this utility model, the upper conveying mechanism 1 is provided with a guide wheel 14 for assisting the upper conveyor belt 11 in transmission. The specific function of the guide wheel 14 is to limit the upper conveyor belt 11 to a certain extent, thereby improving the stability of the upper conveyor belt 11 operation.

[0047] Specifically, the guide wheel 14 includes an inner ring portion 141, an outer ring portion 142, and a cylindrical surface 143. The inner ring portion 141 and the outer ring portion 142 are located at both ends of the cylindrical surface 143, and the top surface of the upper conveyor belt 11 in the transmission channel 3 abuts against the cylindrical surface 143. At the same time, the two side edges of the upper conveyor belt 11 in the transmission channel 3 abut against the inner ring portion 141 and the outer ring portion 142, respectively. It can be understood that in this local position, the upper conveyor belt 11 is limited by at least the inner ring portion 141, the outer ring portion 142, and the cylindrical surface 143. Specifically, the two sides of the upper conveyor belt 11 abut against the inner ring portion 141 and the outer ring portion 142, while the main body of the upper conveyor belt 11 is guided by the cylindrical surface 143.

[0048] In some embodiments of this utility model, the detection component adopts a photoelectric sensor. After the photoelectric sensor detects the corrugated paper material, it transmits the signal to the servo mechanism 4, thereby creating a speed difference between the upper conveyor belt 11 and the lower conveyor belt 21 to achieve the purpose of correction. This content can be referred to the application of photoelectric sensors in the prior art, and will not be elaborated here.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
