Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a corrugated board conveying and correction device. Background Technology

[0002] Corrugated board is a board made of multiple layers of paperboard glued together. It is mostly used in cartons. The corrugated board is prepared into boards on the production line, and then transported to other processes to complete the contour cutting and edge pressing. Finally, the stapling equipment makes it into cartons according to the edge pressing trajectory.

[0003] To prevent corrugated sheets from skewing during transport, patent application number 202220150682.4 discloses a correction device located on both sides of the transport line. The device consists of components such as fixed rollers, springs, and swing arms. A separately set motor is used as the driving component, which positions them on both sides of the transport line and ensures that the corrugated sheets are transported smoothly by rotation.

[0004] However, the power drive used for the above-mentioned correction function is a separate third-party motor, which will generate additional losses during correction. In actual production, the corrugated board will not be skewed because the conveyor line itself is stable. Instead, the corrugated board will be skewed when it is discharged from the discharge end of the conveyor line into the drop environment because of the large drop. For example, when they are discharged and fall on the same stack, the skew angle will be inconsistent, causing them to be uneven when stacked together and collapse. Summary of the Invention

[0005] To address the above problems, the present invention provides a corrugated board conveying and correction device, including a conveyor frame, a conveyor roller at the discharge end of the conveyor frame, a conveyor belt driven on the conveyor roller on the conveyor frame, a first pre-biasing frame assembly and a second pre-biasing frame assembly installed on the conveyor frame, the first pre-biasing frame assembly and the second pre-biasing frame assembly being located on both sides of the conveyor belt and close to the discharge end of the conveyor frame, and the corrugated board being laid flat on the conveyor belt and conveyed towards the discharge end;

[0006] The first pre-biased frame assembly includes two first support rods fixed to one side of the top surface of the conveyor frame. The two first support rods are arranged one after the other. Each of the two first support rods is composed of a spring rod and a first support wheel. The spring rod, along with the first support wheel, is located above the conveyor belt.

[0007] The second pre-biased frame assembly includes two second support rods fixed on the other side of the top surface of the conveyor frame. Each of the two second support rods is equipped with a second support wheel. The two second support rods are arranged one in front of the other. The structure of the two second support rods is the same as that of the two first support rods. They are symmetrically arranged on both sides of the corrugated plate and the first support wheel and the second support wheel form a rolling guide for both sides of the corrugated plate.

[0008] The first support rod is connected to a pre-biased seat located at the discharge end of the conveyor frame. The pre-biased seat and the two first support wheels are arranged one in front of the other. The inner side of the pre-biased seat is provided with an arc-shaped part. The arc-shaped part is biased towards the inner side of the first support wheel. Before the corrugated board is discharged, one side of its discharge end contacts the arc-shaped part and deflects.

[0009] A receiving tray is fixed on the conveyor frame, located below the discharge end of the conveyor belt. An installation hole is provided in the center of the receiving tray. A gearbox is fixed to the discharge end of the conveyor frame, and a friction wheel for receiving corrugated sheets is mounted on the output shaft of the gearbox. The friction wheel is located within the installation hole. A limiting wheel is installed inside the receiving tray, and the limiting wheel is on the same side as the pre-biased seat. When a skewed corrugated sheet falls onto the friction wheel, the rotation of the friction wheel causes the skewed edge of the corrugated sheet to rest against the limiting wheel and be corrected. A stacking device is provided at the discharge end of the conveyor frame, located below the receiving tray, for receiving the corrected corrugated sheets.

[0010] As a further preferred embodiment, the conveyor belt has upwardly protruding pads on its conveying surface, and corrugated plates are placed on the pads, with the pads distributed along the conveying trajectory matrix of the conveyor belt.

[0011] As a further preferred embodiment, the bottom end of the first support wheel is provided with a variable diameter section, the diameter of which is smaller than the diameter of the first support wheel. The shape and diameter of the second support wheel are the same as those of the first support wheel. When the corrugated sheet is guided and conveyed by the first support wheel and the second support wheel, its two sides are restricted within the variable diameter sections at the bottom ends of the first support wheel and the second support wheel.

[0012] As a further preferred embodiment, the discharge end of the conveyor frame is equipped with a vertical frame, the conveyor roller at the discharge end is connected to the vertical frame, one end of the conveyor roller extends outside the vertical frame and is equipped with a drive pulley, the input end of the gearbox is equipped with a drive shaft, the drive shaft extends toward the drive pulley and is equipped with a first driven pulley connected to the drive pulley via a conveyor belt, while the conveyor roller drives the conveyor belt to convey corrugated plates, and also drives the friction wheel to rotate synchronously through the transmission relationship of the gearbox, drive shaft and pulley.

[0013] As a further preferred embodiment, the top surface of the friction wheel is provided with a rubber ring that protrudes from the bottom surface of the inner cavity of the receiving plate.

[0014] As a further preferred embodiment, the receiving plate is provided with a baffle located below and behind the discharge end of the conveyor belt on its rear side, and the receiving plate is provided with a positioning seat on the same side as the second support rod. The positioning seat extends along the discharge side of the receiving plate, and the receiving plate is inclined downward.

[0015] As a further preferred embodiment, a second driven pulley is mounted on the output shaft of the gearbox, and the bottom end of the limiting wheel is assembled through a bearing and passes through the bottom of the receiving plate, and a third driven pulley is mounted thereon. The third driven pulley and the second driven pulley are connected by a belt drive, so that when the second driven pulley rotates counterclockwise with the friction wheel toward the limiting wheel, it drives the limiting wheel to rotate counterclockwise by transmitting the synchronous rotation of the third driven pulley.

[0016] As a further preferred embodiment, the palletizing includes a lifting plate and a lifting sleeve fixed to the bottom of the lifting plate, wherein the lifting sleeve is a rubber corrugated seat capable of lifting and lowering.

[0017] The advantages of this invention compared to the prior art are:

[0018] 1. Before the corrugated sheets are discharged, a pre-set tilt angle is introduced. This tilt angle is effectively controlled by the guidance of the first and second support rollers and the pre-tilt seat, preventing inconsistent tilt angles caused by the direct inertial discharge from the conveyor belt and resulting in uneven stacking. The pre-set tilt angle, effectively controlled by the first and second support rollers and the pre-tilt seat, ensures consistent tilt angles when the sheets fall into the receiving tray after the next drop. The friction wheel in the receiving tray instantly straightens the pre-tilted sheets before they fall onto the stack. The corrugated sheets undergo two drop processes during discharge, reducing the overall drop height and breaking down the large drop into two steps. This ensures that all corrugated sheets are stacked and aligned correctly on the same stack, resolving the tilting issue caused by the large drop after discharge.

[0019] 2. The purpose of the friction wheel rotation is to drive the corrugated board to rotate until its inclined surface rests between the limiting wheel and the positioning seat to complete the alignment. The power of the friction wheel comes from the existing conveyor roller on the conveyor frame. The conveyor roller is an existing transmission component on the conveyor frame. Therefore, the rotation power of the friction wheel does not require the addition of a third-party motor, and no additional losses will be generated to complete the alignment of the corrugated board.

[0028] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In one implementation, such as Figures 1-7 As shown:

[0030] This embodiment provides a corrugated board conveying and correction device, including a conveyor frame 1, a conveyor roller 2 at the discharge end of the conveyor frame 1, a conveyor belt 3 driven on the conveyor roller 2 on the conveyor frame 1, a first pre-biasing frame assembly 4 and a second pre-biasing frame assembly 5 installed on the conveyor frame 1, the first pre-biasing frame assembly 4 and the second pre-biasing frame assembly 5 are respectively located on both sides of the conveyor belt 3 and close to the discharge end of the conveyor frame 1, the corrugated board is laid flat on the conveyor belt 3 and conveyed towards the discharge end by the conveyor belt 3.

[0031] The first pre-biased frame assembly 4 includes two first support rods 41 fixed on one side of the top surface of the conveyor frame 1. The two first support rods 41 are arranged one after the other. Each of the two first support rods 41 consists of a spring rod 411 and a first support wheel 412. The spring rod 411 and the first support wheel 412 are located above the conveyor belt 3.

[0032] The second pre-biased frame assembly 5 includes two second support rods 51 fixed on the other side of the top surface of the conveyor frame 1. Each of the two second support rods 51 is provided with a second support wheel 511. The two second support rods 51 are arranged one in front of the other. The structure of the two second support rods 51 is the same as that of the two first support rods 41. They are symmetrically arranged on both sides of the corrugated plate and the first support wheel 412 and the second support wheel 511 form a rolling guide for both sides of the corrugated plate.

[0033] The first support rod 41 is connected to a pre-biased seat 42 located at the discharge end of the conveyor frame 1. The pre-biased seat 42 and the two first support wheels 412 are arranged in front and behind. The inner side of the pre-biased seat 42 is provided with an arc-shaped part 421. The arc-shaped part 421 is biased towards the inner side of the first support wheel 412. Before the corrugated board is discharged, one side of its discharge end contacts the arc-shaped part 421 and becomes biased.

[0034] Because a first pre-biasing frame assembly 4 is set on one side of the conveying direction and a second pre-biasing frame assembly 5 is set on the other side, the pre-biasing effect can be achieved in advance when the corrugated board is discharged from the output end through the cooperation of the first pre-biasing frame assembly 4 and the second pre-biasing frame assembly 5. The pre-biasing angle of the corrugated board is limited by the cooperation of the first pre-biasing frame assembly 4 and the second pre-biasing frame assembly 5. The specific principle is as follows: when the conveyor belt 3 conveys the corrugated board to the discharge end, the front corner of the corrugated board will first contact the arc-shaped part 421. Since the arc-shaped part 421 is biased to the inside of the first support roller 412, the front end of the corrugated board will be biased towards the second support roller 511 and the rear end of the corrugated board will be biased towards the first support roller 412 under the restriction of the arc-shaped part 421. This makes the second support roller 511 and the first support roller 412 closer to the discharge end buffered and compressed to conform to the biasing angle of the corrugated board. After the corrugated sheet is output in the aforementioned pre-biased manner, it falls onto the receiving tray 6. Since the drop between the receiving tray 6 and the conveyor belt 3 is small, the pre-bias angle of the corrugated sheet does not change significantly when it falls onto the receiving tray 6. Because the mounting hole 61 of the receiving tray 6 is equipped with a friction wheel 71, the friction wheel 71 rotates the pre-biased corrugated sheet, causing the inclined edge of the pre-biased corrugated sheet to approach the limiting wheel 62. Under the limiting action of the limiting wheel 62, the corrugated sheet is fixed and aligned. The friction wheel 71 rotates towards the side where the limiting wheel 62 is located. Figure 1 The friction wheel 71 shown rotates counterclockwise. When it rotates, it can instantly rotate the corrugated plate, causing the right side of the corrugated plate to be brought closer to the limiting wheel 62 and the left side to be brought closer to the inner side of the positioning seat 64. Under the forced restraint of the limiting wheel 62 and the positioning seat 64, the corrugated plate is instantly straightened.

[0035] When the friction wheel 71 continues to rotate on the bottom surface of the corrugated sheet, the frictional force generated is less than the limiting force of the corrugated sheet against the limiting wheel 62. Therefore, the friction wheel 71 will not carry the corrugated sheet along with it as it continues to rotate. Furthermore, since the receiving tray 6 is tilted downwards towards the discharge end, after the corrugated sheet is instantly straightened, the inertial force generated by the tilting structure of the receiving tray 6 falls onto the next drop stack 8. Through these two falling actions, the drop height of the corrugated sheet during discharge is reduced. Pre-deviation control and correction processes ensure that the corrugated sheet is ultimately positioned correctly on the stack 8.

[0036] In summary, in this embodiment, a deflection angle is preset before the corrugated board is discharged. This deflection angle can be effectively controlled under the guidance and restriction of the first support wheel 412, the second support wheel 511 and the pre-deflection seat 42, so as to avoid the inconsistency of the deflection angle when the corrugated board is discharged directly from the discharge end of the conveyor belt 3 by inertia, which would result in unevenness when it finally falls on the stacking 8. In this embodiment, a pre-set tilt angle is used before the corrugated board is unloaded. This tilt angle is effectively controlled by the cooperation of the first support wheel 412, the second support wheel 511, and the pre-tilt seat 42. Therefore, the tilt angle is consistent when the board falls into the receiving tray 6 of the next drop. After the friction wheel 71 in the receiving tray 6 rotates instantaneously, the limiting wheel 62 and the positioning seat 64 restrict and align the board on both sides before it falls onto the stacking 8 of the next drop. Thus, the corrugated board undergoes two drop processing steps during unloading. These two drop processing steps reduce the drop height and decompose the large drop during unloading into two drop steps, ensuring that all corrugated boards can be stacked and aligned correctly when unloaded onto the same stacking 8. This solves the problem of tilting due to the large drop after unloading.

[0037] like Figures 1 to 4 As shown, the conveyor surface of the conveyor belt 3 is provided with upwardly protruding pads 31. Corrugated sheets are placed on the pads 31, which are distributed along the conveyor track matrix of the conveyor belt 3. The pads 31 are conveyed towards the discharge end by the conveyor belt 3, and the corrugated sheets are delivered to the discharge end by the pads 31. The corrugated sheets are supported by the pads 31, thus forming a space with the surface of the conveyor belt 3. The bottom end of the first support wheel 412 is provided with a variable diameter part, the diameter of which is smaller than the diameter of the first support wheel 412. The shape and diameter of the second support wheel 511 are the same as those of the first support wheel 412. Under the action of the variable diameter section of the two support wheels, when the corrugated sheet is guided and conveyed by the first support wheel 412 and the second support wheel 511, its two sides are restricted within the variable diameter section at the bottom of the first support wheel 412 and the second support wheel 511. During the conveying process, the top of the first support wheel 412 and the second support wheel 511 restricts the top surface of the corrugated sheet, preventing the corrugated sheet from warping. When the corrugated sheet is discharged to the point where its discharge end contacts the arc-shaped part 421 on the pre-eccentric seat 42 and causes an oblique action, the biasing force generated by its two sides on the first support wheel 412 and the second support wheel 511 enables them to perform corresponding extension and retraction actions.

[0038] In another implementation, such as Figure 1 , Figure 5 as well as Figure 6 As shown, a vertical frame 101 is installed at the discharge end of the conveyor frame 1. The conveyor roller 2 at the discharge end is connected to the vertical frame 101 (mounted via bearings). In addition, in this embodiment, one end of the conveyor roller 2 extends through the vertical frame 101, and a drive pulley 9 is installed on the extended end of the conveyor roller 2. A drive shaft 72 is installed at the input end of the gearbox 7. The drive shaft 72 extends to the same side as the drive pulley 9 and is equipped with a first driven pulley 10. The first driven pulley 10 is connected to the drive pulley 9 via a conveyor belt. While the conveyor roller 2 drives the conveyor belt 3 to convey the corrugated board, it also drives the friction wheel 71 to rotate synchronously through the gearbox 7, drive shaft 72 and pulley transmission relationship. To prevent the corrugated board from skewing during discharge, it is only necessary to control the conveyor roller 2 to rotate at a slow speed. Under this existing control technology, the conveyor roller 2 also drives the drive pulley 9 to rotate at a slow speed. The drive pulley 9 drives the first driven pulley 10 to rotate at a slow speed through belt transmission. The first driven pulley 10 drives the drive shaft 72 to rotate at a slow speed. The output end of the drive shaft 72 transmits this slow rotation to the friction wheel 71 after meshing with the gear set in the gearbox 7. Since the purpose of the rotation of the friction wheel 71 is to drive the corrugated board to rotate until its inclined surface rests between the limiting wheel 62 and the positioning seat 64 to complete the alignment, the power of the friction wheel 71 actually comes from the conveyor roller 2. The conveyor roller 2 is an existing transmission component on the conveyor frame 1. Therefore, the rotation power of the friction wheel 71 does not require the addition of a third-party motor, and no additional losses are generated to complete the correction of the corrugated board.

[0039] like Figure 3 As shown, the top surface of the friction wheel 71 is provided with a rubber ring 73 on the bottom surface of the inner cavity of the protruding receiving plate 6, which increases the friction force on the bottom surface of the corrugated plate when the corrugated plate is corrected and aligned, ensuring that the corrugated plate is effectively aligned.

[0040] As shown in the figure, a baffle 63 is provided on the rear side of the receiving plate 6, located below and behind the discharge end of the conveyor belt 3. When the corrugated plate is tilted and straightened by the rotation of the friction wheel 71, its rear side is restricted by the baffle 63, one side of the tilt is restricted by the limiting wheel 62, and the other side of the tilt is restricted by the positioning seat 64, so as to ensure that the corrugated plate is effectively corrected and straightened within the receiving plate 6.

[0041] like Figure 6 , Figure 7As shown, in another embodiment, the top of the output shaft of the gearbox 7 is not only used to install the friction wheel 71, but also to install a second driven pulley 11 on the output shaft of the gearbox 7. The limiting wheel 62 is mounted on the receiving plate 6 through a bearing. The bottom end of the limiting wheel 62 extends to the bottom of the receiving plate 6, and a third driven pulley 12 is installed at the bottom end of the limiting wheel 62. The third driven pulley 12 and the second driven pulley 11 are connected by a belt drive, so that when the second driven pulley 11 rotates counterclockwise with the friction wheel 71 toward the limiting wheel 62, it drives the limiting wheel 62 to rotate counterclockwise by transmitting the synchronous rotation of the third driven pulley 12. The friction wheel 71 corrects and straightens the corrugated sheet that has fallen and tilted in the receiving tray 6 by rotating counterclockwise. The limiting wheel 62 rotates counterclockwise at the same time, which is equivalent to rolling on the right side of the corrugated sheet to make the corrugated sheet discharge towards the stacking 8. Even after the corrugated sheet is corrected and straightened, it can be discharged quickly by taking advantage of the tilting inertia of the receiving tray 6. The rotation of the limiting wheel 62 can help to push the corrugated sheet to discharge quickly. Stacking 8 utilizes the top lifting plate 81 to pick up corrugated sheets. Each corrugated sheet landing on the lifting plate 81 increases its load, causing the lifting sleeve 82 to descend once, stacking all the corrugated sheets on the lifting plate 81. The lifting plate 81 is not limited to having a flat top surface; it can also serve as a material hopper. Since each corrugated sheet is adjusted to be properly aligned before landing on the lifting plate 81, when the top surface of the lifting plate 81 is a material hopper, it further ensures that the stacked corrugated sheets will not collapse. In the next process, the robotic arm accurately picks up and transfers them one by one according to the set parameters.
