Technical Field

[0001] This utility model relates to the field of glass fiber technology, and specifically to a conveying system for yarn rolls. Background Technology

[0002] In fiberglass production, some varieties require connecting two or more yarn roll ends to ensure product continuity for downstream customers; other varieties do not require splicing. Currently, the transfer of batches of yarn rolls, whether spliced ​​or not, often requires significant manual intervention, which has the following drawbacks:

[0003] 1. High labor intensity: Workers need to perform repetitive tasks for long periods of time, which is physically demanding and may affect work efficiency and worker health;

[0004] 2. Significant impact on personal safety: In the working environment, the small diameter of fiberglass produces a lot of dust, which poses certain hazards to workers' respiratory system and skin.

[0005] 3. The efficiency is relatively low.

[0006] Therefore, how to provide a yarn roll conveying system that can avoid the above-mentioned defects has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] To achieve the above objectives, this utility model provides an automatic splicing and automatic palletizing laminating machine that realizes automatic splicing and automatic palletizing. The specific technical solution is as follows:

[0008] A conveying system for yarn rolls, characterized in that it includes a main belt conveyor for conveying a plurality of single yarn rolls arranged at intervals, the single yarn rolls being formed into batches of yarn rolls that require splicing with each other or do not require splicing with each other, the batches of yarn rolls requiring splicing being a plurality of first yarn rolls, and the batches of yarn rolls not requiring splicing being a plurality of second yarn rolls, wherein the splicing is the connection between the inner and outer splices of two adjacent upper and lower first yarn rolls after the plurality of first yarn rolls are stacked, and a branch conveyor line is provided downstream of the main belt conveyor, namely a first branch conveyor line and a second branch conveyor line, the first branch conveyor line being used to convey a plurality of first yarn rolls and the second branch conveyor line being used to convey a plurality of second yarn rolls, and further includes a controller, which is electrically connected to a main motor driving the main belt conveyor line, a first motor driving the first branch conveyor line, and a second motor driving the second branch conveyor line.

[0009] Preferably, the second branch conveyor line includes a roller conveyor line and a main belt extension conveyor line. The roller conveyor line includes a support platform and several rollers. The support platform is located downstream of the main belt conveyor line. The several rollers are arranged in parallel at intervals and are all at the same height as the main belt conveyor line. The axial direction of each roller is perpendicular to the conveying direction of the main belt conveyor line. Support plates are mounted on the upper surface of the support platform at the two ends corresponding to the axial direction of each roller. The two ends of each roller along the axial direction are rotatably connected to the corresponding support plates. A transmission section is formed at one end of each roller on the same side along the axial direction. The roller closest to the main belt is the first roller. An input sprocket and an output sprocket are mounted on the transmission section of the first roller. A fifth motor is also included, with a sprocket fixed to its output end. This sprocket is connected to the input sprocket via a chain. The output sprocket is connected to the input sprocket on the transmission section of the second roller adjacent to the first roller via a chain. The transmission sections between any two adjacent rollers are connected via a sprocket and chain drive. A main belt extension conveyor is located downstream of the roller furthest from the main belt. The roller and the main belt extension conveyor are at the same height.

[0010] The first branch conveyor line includes several sorting belts for sorting the first yarn rolls. One sorting belt is set between two rollers that are spaced apart. It also includes a lifting cylinder and a lifting platform at its end. The lifting platform is located above the support platform and below the rollers. Several sorting belts are set on the lifting platform. A main drive rod is set on the lifting platform at the same end of the sorting belts. It also includes a sixth motor. The sixth motor is connected to one end of the main drive rod via belt drive. One end of each sorting belt is sleeved on the main drive rod, and the other end of each sorting belt is sleeved on a separate rotating rod. The separate rotating rod is set on the lifting platform.

[0011] The controller is electrically connected to the fifth motor, the sixth motor, the lifting cylinder, and the seventh motor that controls the start and stop of the main belt extension conveyor line;

[0012] When the second branch conveyor line conveys several second yarn rolls, the lifting cylinder is in a retracted state, causing several sorting belt lines to be lower than the roller. When the first branch conveyor line conveys several first yarn rolls, the roller conveyor line and the main belt extension line stop operating, and the lifting cylinder is in an extended state, causing several sorting belt lines to be at the same height as the main belt line and the transmission belt line.

[0013] Preferably, the number of rollers is 5 and the number of sorting conveyor belts is 4.

[0019] The yarn roll conveying system provided by this utility model has the following technical effects:

[0020] This system can be used to transport either a batch of first yarn rolls or a batch of second yarn rolls individually. When transporting several second yarn rolls, the lifting cylinder is in a retracted state, causing several sorting conveyor belts to be lower than the roller. The main conveyor belt, roller conveyor belt, and main conveyor belt extension conveyor belt are used to complete the transport of several second yarn rolls. When transporting several first yarn rolls, the roller conveyor belt and the main conveyor belt extension conveyor belt stop operating, and the lifting cylinder is in an extended state, causing several sorting conveyor belts to be at the same height as the main conveyor belt and the transport conveyor belt. The main conveyor belt and sorting conveyor belt belt are used to complete the transport of several first yarn rolls.

Detailed Implementation

[0031] like Figure 1-5As shown, this utility model provides an automatic splicing and palletizing laminating machine, comprising a main belt 1 for conveying a plurality of single yarn rolls arranged at intervals. These single yarn rolls are formed into batches of yarn rolls that require splicing with each other or do not require splicing with each other. The batches of yarn rolls requiring splicing are a plurality of first yarn rolls 2, and the batches of yarn rolls that do not require splicing are a plurality of second yarn rolls 3. The splicing is achieved by connecting the inner and outer splices of two adjacent upper and lower first yarn rolls 2 after stacking. A branch conveyor line is provided downstream of the main belt 1, namely a first branch conveyor line and a second branch conveyor line. The first branch conveyor line is used to convey a plurality of first yarn rolls 3. The yarn roll 2 and the second branch conveyor line are used to convey a plurality of second yarn rolls 3. The second branch conveyor line also includes a stacking joint 4, which is located downstream of the first branch line for stacking and jointing a plurality of first yarn rolls 2. The second branch conveyor line also includes a transfer section, which is used to move the second yarn rolls 3 on the second branch conveyor line to a desired position or to move a plurality of first yarn rolls 2 that have been joined in the stacking joint 4 to a desired position. The second branch conveyor line also includes a controller, which is electrically connected to the main motor driving the main belt 1, the first motor driving the first branch conveyor line, the second motor driving the second branch conveyor line, the stacking joint 4, and the transfer section.

[0032] like Figure 1-5 As shown, in one specific embodiment, the palletizing joint includes:

[0033] The transmission belt 5 and the third motor that drives its operation are connected at the beginning of the transmission belt 5 to the end of the first branch conveyor line for receiving the plurality of first yarn rolls 2. The inner and outer joints of each of the plurality of first yarn rolls 2 are arranged opposite to each other and are exposed on both sides of the outer side wall of the first yarn roll 2. In two adjacent first yarn rolls: the inner joint of the upstream first yarn roll 2 and the outer joint of the downstream first yarn roll 2 are exposed on the outer side wall of their respective first yarn roll 2 in the same position, and the outer joint of the upstream first yarn roll 2 and the inner joint of the downstream first yarn roll 2 are exposed on the outer side wall of their respective first yarn roll 2 in the same position.

[0034] The yarn roll stacking conveyor belt 6 and the fourth motor that drives its operation are used to transport the yarn roll stack 66 after several first yarn rolls 2 have been stacked. The yarn roll stacking conveyor belt 6 has a first side and a second side. The direction from the first side to the second side is perpendicular to the conveying direction of the yarn roll stacking conveyor belt 6. In the direction towards the first side, the inner and outer joints of the upper and lower adjacent first yarn rolls 2 are arranged alternately. In the direction towards the second side, the inner and outer joints of the upper and lower adjacent first yarn rolls 2 are distributed alternately.

[0035] A stacking mechanism for moving the first yarn roll 2 located on the conveyor belt 5 to the yarn roll stacking conveyor belt 6 for stacking.

[0036] A plurality of splicing mechanisms 7 are provided, the number of which is less than the number of the first yarn rolls 2 in the yarn roll stack 66, and the difference between the two is 1. The plurality of splicing mechanisms 7 are arranged sequentially along the conveying direction of the yarn roll stack conveyor belt 6, and the sequential arrangement is alternately distributed along the first side and the second side of the yarn roll stack conveyor belt 6, and the alternation is staggered in height. This arrangement improves efficiency by simultaneously splicing the yarn roll stacks 66 located at different positions on the yarn roll stack conveyor belt 6.

[0037] A plurality of yarn roll stacking and pressing mechanisms are provided, the number of which is the same as the number of joint mechanisms 7. The plurality of yarn roll stacking and pressing mechanisms are arranged sequentially along the direction of the yarn roll stacking conveyor belt 7 and are all located above the conveyed yarn roll stack 66. Each yarn roll stacking and pressing mechanism can move back and forth synchronously in the horizontal direction and in the vertical direction, so that the yarn roll stacking conveyor belt 6 can press the top of the corresponding yarn roll stack 66 when conveying the yarn roll stack 66.

[0038] The controller is electrically connected to a third motor, a fourth motor, a stacking mechanism, several joint mechanisms 7, and several yarn roll stacking and pressing mechanisms.

[0039] In one specific implementation, such as Figure 1-5 As shown, the connector mechanism 7 includes:

[0040] Mounting base 8 has an internal space. The inner and outer joints of the two adjacent first yarn rolls 2 facing the yarn roll stack 66 are open. The side wall of the mounting base 8 away from the yarn roll stack 66 corresponding to the internal space is a first side wall 9. The side wall adjacent to the internal space and perpendicular to the first side wall 9 is a second side wall 10. Two perforations are opened on the first side wall 9.

[0041] Each of the perforations is provided with a telescopic rod 11 that moves back and forth in the horizontal direction. The end of the telescopic rod 11 is fixed with a suction cup 12 that can pick up the inner or outer connector. The system also includes a first cylinder that synchronously drives the two telescopic rods 11 to move back and forth and a vacuum solenoid valve that controls the suction cup 12 to generate suction.

[0042] A rectangular through hole is formed on the second sidewall 10 near the first sidewall 9. The long side of the rectangular through hole extends vertically in the opposite direction, and the short side extends horizontally. The two long sides are a first long side 13 and a second long side 14. The first long side 13 is close to the first sidewall 9. A telescopic cylinder 15 is provided on the inner sidewall of the first long side 13. A clamping cylinder 24 is provided at the end of the telescopic cylinder 15. The second sidewall 10 also includes a first rodless cylinder 28 that drives the telescopic cylinder 15 to move up and down along the first long side. A telescopic cylinder 22 is provided on the inner sidewall of the second long side 14. A clamping cylinder 27 is provided at the end of the telescopic cylinder 22. The second sidewall 10 also includes a second rodless cylinder 29 that drives the telescopic cylinder 22 to move up and down along the second long side 14. Two vertically distributed through holes are formed on the second sidewall 10 away from the boundary of the first sidewall 9. There are two through holes, an upper through hole 30 and a lower through hole 31. The positions of the two through holes in the horizontal direction correspond one-to-one with the two through holes on the first side wall 9. A telescopic cylinder 16 is provided at the position of the upper through hole 30. A clamping cylinder 25 is provided at the end of the telescopic cylinder 16. A telescopic cylinder 19 is provided at the position of the lower through hole 31. A clamping cylinder 26 is provided at the end of the telescopic cylinder 19. In the initial state: the telescopic cylinder 15 on the first side wall 9 and the telescopic cylinder 16 at the upper through hole 30 are at the same height. The clamping cylinders at the ends of the two are at the same height and can be directly opposite the suction cup 12 of the telescopic rod 11 above to suck up the yarn. The telescopic cylinder 22 on the second long side 14 and the telescopic cylinder 19 at the lower through hole 31 are at the same height. The clamping cylinders at the ends of the two are at the same height and can be directly opposite the suction cup 12 of the telescopic rod 11 below to suck up the yarn.

[0043] A telescopic cylinder is provided on the second side wall 10 at a position close to and flush with the upper through hole 30. A yarn sensor 32 is provided at the end of the telescopic cylinder 17. A telescopic cylinder 20 is provided on the second side wall 10 at a position close to and flush with the lower through hole 31. A yarn sensor 32 is provided at the end of the telescopic cylinder 20. The two yarn roll sensors 32 are arranged in the vertical direction.

[0044] A telescopic cylinder 23 is provided at the middle position between two yarn sensors 32. An air splicer 33 controlled by a solenoid valve is fixed to the end of the telescopic cylinder 23. A telescopic cylinder 18 is provided between the air splicer 33 and the upper yarn sensor 32. A W-shaped yarn overlap structure 34 is fixed to the end of the telescopic cylinder 18. A telescopic cylinder 21 is provided between the air splicer 33 and the lower yarn sensor 32. A W-shaped yarn overlap structure 34 is fixed to the end of the telescopic cylinder 21. The two W-shaped gaps of the two W-shaped yarn overlap structures 34 are used for the overlap of the yarn roll.

[0045] The mounting base 8 also includes a waste yarn collection funnel 35 located below and communicating with its internal space, the waste yarn collection funnel 35 being located below the protruding air splicer 33;

[0046] The controller is electrically connected to the first cylinder, the vacuum solenoid valve, all telescopic cylinders and clamping cylinders, the yarn sensor and the solenoid valve.

[0047] The vacuum suction of the connector mechanism is provided by vacuum pump 67.

[0048] like Figure 1-5 In one specific embodiment, the second branch conveyor line includes a roller conveyor line and a main belt extension conveyor line 41. The roller conveyor line includes a support platform 36 and a plurality of rollers 37. The support platform 36 is located downstream of the main belt line 1. The plurality of rollers 37 are arranged in parallel at intervals and are all at the same height as the main belt line 1. The axial direction of each roller 37 is perpendicular to the conveying direction of the main belt line 1. Support plates 38 are mounted on the upper surface of the support platform 36 at the positions corresponding to the two ends of each roller 37 along the axial direction. The two ends of each roller 37 along the axial direction are rotatably connected to the corresponding support plates 38. The ends of the plurality of rollers 37 located on the same side along the axial direction are all formed The system includes a transmission section. Among the plurality of rollers 37, the roller closest to the main belt line 1 is the first roller 39. The transmission section of the first roller 39 is equipped with an input sprocket and an output sprocket, and also includes a fifth motor 40. The output end of the fifth motor 40 is fixed with a sprocket, which is driven by a chain to the input sprocket. The output sprocket is driven by a chain to the input sprocket on the transmission section of the second roller adjacent to the first roller 39. The transmission section between each pair of adjacent rollers 37 is driven by a sprocket and chain. The main belt extension conveyor line 41 is provided downstream of the roller 37 that is away from the main belt line 1. The roller 37 and the main belt extension conveyor line 41 are at the same height.

[0049] The first branch conveyor line includes several sorting belts 42 for sorting the first yarn rolls 2. One sorting belt 42 is arranged between two rollers 37 that are spaced apart. It also includes a lifting cylinder 43 and a lifting platform 44 located at its end. The lifting platform 44 is located above the support platform 36 and below the several rollers 37. Several sorting belts 42 are arranged on the lifting platform 44. A main drive rod 45 is arranged on the lifting platform 44 at the same position corresponding to the same end of several sorting belts 42. It also includes a sixth motor 46. The sixth motor 46 is connected to one end of the main drive rod 45 through belt drive. One end of each sorting belt 42 is sleeved on the main drive rod 45, and the other end of each sorting belt 42 is sleeved on a separate rotating rod. The separate rotating rod is arranged on the lifting platform 44.

[0050] The controller is electrically connected to the fifth motor 40, the sixth motor 46, the lifting cylinder 43, and the seventh motor that controls the start and stop of the main belt extension conveyor line 41.

[0051] When the second branch conveyor line conveys several second yarn rolls 3, the lifting cylinder 43 is in a retracted state, causing several sorting belt lines 42 to be lower than the roller 37. When the first branch conveyor line conveys several first yarn rolls 2, the roller conveyor line and the main belt extension conveyor line 41 stop operating and the lifting cylinder 43 is in an extended state, causing several sorting belt lines 42 to be at the same height as the main belt line 1 and the transmission belt line 5.

[0052] The number of first yarn rolls 2 in each yarn roll stack 66 is 4.

[0053] like Figure 1-5 As shown, in one specific embodiment, the palletizing joint 4 further includes a joint support platform 47. The conveyor belt 5 and the yarn roll stacking conveyor belt 6 are both arranged on the joint support platform 47, and their conveying directions are perpendicular. The starting end of the yarn roll stacking conveyor belt 6 is close to the end of the conveyor belt 5. A first slide rail 48 is provided above the end of the conveyor belt 5. The extension direction of the first slide rail 48 is perpendicular to the conveying direction of the conveyor belt 5. A slider is slidably installed on the first slide rail 48. A robotic arm 49 capable of rotating 90° is installed at the end of the slider. The first slide rail 48 is supported by a second slide rail 50 arranged vertically and fixed on the joint support platform 47. The first slide rail 48 is slidably connected to the second slide rail 50. The system also includes a first cylinder that drives the first slide rail 48 to slide up and down along the second slide rail 50, and a second cylinder that drives the slide rail to reciprocate along the first slide rail 48. The controller is electrically connected to the robotic arm 49, the first cylinder, and the second cylinder.

[0054] Each of the yarn roll stacking and pressing mechanisms includes a third cylinder and a circular pressure plate 51 located at the end of the third cylinder. The size of the circular pressure plate 51 matches the size of the yarn roll. The extension and retraction direction of the third cylinder is vertical. It also includes a third slide rail 52. The extension direction of the third slide rail 52 is the same as the conveying direction of the yarn roll stacking conveyor belt 6. The third slide rail 52 is supported on the joint support platform 47 by a support rod. All three third cylinders are fixed on a moving rod that can reciprocate along the third slide rail 52. It also includes a fourth cylinder that drives the moving rod to reciprocate. The controller is electrically connected to the third cylinder and the fourth cylinder.

[0055] In this specific implementation, such as Figure 2As shown, the positions of the inner and outer joints of the second yarn roll 3, conveyed by the conveyor belt 5, are already determined (similarly, the positions of the inner and outer joints of the adjacent second yarn rolls 3 on the main conveyor belt 1 are also determined; after passing through the sorting conveyor belt 42, the orientation of the second yarn roll 3 has been rotated ninety degrees). From the diagram, the direction of the inner joint towards the outer joint is perpendicular to the conveying direction of the conveyor belt 5. Then, a sensor located on one side of the conveyor belt 5 is used to detect whether a second yarn roll 3 has passed. If detected, a signal is transmitted to the controller, which then controls the robotic arm 49 to move along the first slide rail 48, and the first slide rail 48 to move along the second slide rail 50. The robotic arm 49 then rotates 90° to grab the second yarn roll 3, and then resets to place the second yarn roll 3 on the yarn roll stacking conveyor belt 6. When four second yarn rolls 3 are grabbed to form a yarn roll stack 66, the controller controls the splicing mechanism 7 to operate. After the splicing action is completed, the controller will drive the yarn roll stacking and pressing mechanism to operate, causing its circular pressure plate 51 to press against the top of the yarn roll stack 66 and slide along the third slide rail 52, synchronously following the yarn roll stack along the conveying direction of the yarn roll stack conveyor belt 6. It is understood that a sensor electrically connected to the controller is also installed on one side of the main conveyor belt 1. This sensor is used to detect whether the first yarn roll 2 has passed by. If detected, it transmits a signal to the controller to control the sorting conveyor belt 42 to operate while the roller 37 and the main conveyor belt extension 41 remain inactive. Correspondingly, when the second yarn roll 3 is being conveyed in batches, after the sensor detects the second yarn roll 3, the controller will control the roller 37 and the main conveyor belt extension 41 to operate while the sorting conveyor belt 42 remains inactive.

[0056] In one specific implementation, such as Figure 1-5 As shown, the transfer unit includes a 6-axis robot 53 and a fixture placement frame 54. The fixture placement frame 54 holds a splicing stacking fixture 55, a non-splicing stacking fixture 56, and a cardboard suction fixture 57. The splicing stacking fixture 55 is used to grab the yarn rolls that have been spliced ​​and stacked 66 that are conveyed by the yarn roll stacking conveyor belt 6. The non-splicing stacking fixture 56 is used to grab each second yarn roll 3 that is conveyed by the main belt extension line 41. The cardboard suction fixture 57 is used to grab the cardboard. The splicing stacking fixture 55, the non-splicing stacking fixture 56, and the cardboard suction fixture 57 can all be detachably connected to the robotic arm of the 6-axis robot 53.

[0057] This includes a cardboard placement station 65, which is used to place several stacked cardboards.

[0058] Sorting conveyor 42 is used to sort and transport the first yarn roll 2, which requires splicing, from the main conveyor 1 to the splicing station. The main conveyor extension 41 is mainly used to transport the second yarn roll 3, which does not require splicing, to the palletizing station of the 6-axis robot 53, where the 6-axis robot 53 directly pallets it. Figure 1-5 As shown, all different fixtures use the robot quick-change plate 58 as a unified interface. The robot quick-change plate 58 has a power interface, a signal line interface, and an air source interface, which can provide power, air source and control signal requirements for the fixtures. The joint palletizing fixture 55 uses two servo grippers 59 to grab the yarn rolls and stack them 66. The non-joint palletizing fixture 56 uses a cylinder 60 as a power to drive the yarn roll clamping gripper 61 to grab a single second yarn roll 3 and stack it to the required station. The cardboard suction fixture 57 uses a vacuum generator 62 to generate a vacuum degree. The vacuum suction cup 64 set on the aluminum alloy fixture bracket 63 picks up the cardboard and places it on the palletizing tray at the partition of the placement station 65.

[0059] like Figure 1 As shown, the second yarn roll 3, which does not require a joint, is transported from the main conveyor belt 1, via several rotating rollers 37 (while the sorting conveyor belt 42 is stopped) and the main conveyor belt extension 41. A 6-axis robot 53, carrying corresponding grippers, holds the second yarn roll 3 for stacking. After one layer of yarn rolls is stacked, the 6-axis robot 53 changes grippers to grab a paper divider and place it on the stacking pallet, then changes grippers again to continue grabbing the second yarn roll for stacking. This process is repeated until stacking is complete. Figure 1 As shown, the first yarn roll 2 that needs to be spliced ​​is transmitted from the main belt 1. The first yarn roll 2 is transmitted into the stacking splicing section through the sorting belt 42 (at this time, several rollers 37 are in a stopped state) for splicing and stacking operations. After the splicing operation is completed, the stacked yarn roll is output by the yarn roll stacking conveyor 6. Then, the 6-axis robot 53 carries the corresponding fixture to stack the yarn roll to the required work station.

[0060] When the joint mechanism is connected, it is combined Figure 3 As shown:

[0061] Reset position: All telescopic cylinders retract (15-23), all clamping cylinders open (24-27), the first rodless cylinder 28 stops at the position shown in the figure (telescopic cylinders 15 and 16 are on a line), the second rodless cylinder 29 stops at the position shown in the figure (telescopic cylinders 19 and 22 are on a line), the telescopic rod 11 and the suction cup 12 on it retract to the pattern shown in the figure, and all air nozzle blowing and vacuum solenoid valves are closed.

[0062] Action flow:

[0063] 1. The telescopic rod 11 and the suction cup 12 on it extend (this action can be achieved by configuring a corresponding cylinder) →→→→→ The vacuum solenoid valves that connect the suction cups to generate suction force are opened respectively, wait for N seconds →→→→→ The telescopic rod 11 and the suction cup 12 on it retract.

[0071] The air splicer 33 used to join the intersection of two crossed yarns is existing technology and will not be described in detail here. The air splicer 33 is a commercially available product, and its specific structure will not be described in detail here.

[0072] This equipment processes either a batch of first yarn rolls 2 or a batch of second yarn rolls 3. For example, if all the yarn rolls in this batch are first yarn rolls 2 that require splicing, then the first yarn rolls 2 are conveyed sequentially through the main belt 1 and then enter the stacking splicing section to complete the corresponding actions. If all the yarn rolls in this batch are second yarn rolls 3 that do not require splicing, then the conveying is completed through the main belt 1, roller 37 and main belt extension conveyor 41.
