Description

Technical Field

[0001] This invention relates to the field of roll material feeding technology, specifically to an oscillating feeder and feeding method. Background Technology

[0002] Oscillating feeders are a type of feeding technology used in automated production (such as stamping, assembly, welding, etc.). The core of oscillating feeders is to solve the need for simultaneous processing of multiple materials in order to improve production efficiency or achieve composite processing. They are suitable for industries with special requirements for material combinations, efficiency, or functions.

[0003] During the conveying process, it is necessary to ensure that the conveyed material does not deviate from its intended path to prevent misalignment during subsequent processing. To address this, adjustable guide rollers can be installed on both sides of the conveyor belt, and the spacing between the guide rollers can be adjusted according to the width of the conveyor belt. A channel is formed between the two guide rollers to constrain the conveyor belt.

[0004] However, if some thinner and softer materials are deviated due to external force or improper operation, since the guide roller is in a rigid state, the side of the material acts directly on the guide roller. The greater the deviation, the greater the force. During continuous feeding, the material will continuously rub against the guide roller, which will lead to the problem of the material edge curling or breaking.

[0005] To address this, flexible guide rollers can be used to limit the material's movement. These rollers can perform a yielding action when the material deviates and effectively absorb the offset force, thus preventing damage to the material's edges. However, if the flexible guide rollers cannot quickly and effectively guide the material back to its original position after yielding, it will lead to an increase in the overall offset of the material, which in turn will cause misalignment during subsequent processing, resulting in a decrease in processing accuracy. Summary of the Invention

[0006] The purpose of this invention is to provide a swing feeder and a feeding method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An oscillating feeder, comprising:

[0009] The workbench and the slide rail fixed on the workbench, the feeding table is slidably installed on the slide rail, the feeding table is fixed with symmetrically arranged fixed plates, and the conveying rollers are rotatably installed on the fixed plates.

[0010] Also includes:

[0011] The gear is rotatably mounted on the workbench, and a rack plate that meshes with the gear is fixed at the bottom of the feeding table;

[0012] A bidirectional translation mechanism is mounted on a fixed plate, including a movable plate and a limiting plate fixed on the movable plate. The movable plate is provided with a clamping mechanism, which includes symmetrically arranged limiting wheels.

[0013] A flexible support mechanism is installed on the bidirectional translation mechanism. When the limiting wheel is subjected to force, the flexible support mechanism can adjust the support force on the limiting wheel through a movable plate and a clamping mechanism.

[0014] As a further embodiment of the present invention: the bidirectional translation mechanism includes a bidirectional lead screw rotatably mounted on the fixed plate, and threaded sleeves arranged symmetrically connected to the bidirectional lead screw. A support plate and a guide rail are fixed to the side wall of the threaded sleeves, and a support rod is fixed to the support plate. The support rod and the guide rail are slidably connected to the movable plate.

[0015] As a further embodiment of the present invention: the bidirectional translation mechanism further includes a guide post fixed on the fixed plate, the guide post having a guide sleeve that slides axially, and the guide sleeve being fixedly connected to the threaded sleeve.

[0016] As a further embodiment of the present invention: the clamping mechanism includes a second sliding groove formed on the movable plate and symmetrically arranged, and a sliding block is slidably installed in the second sliding groove;

[0017] It also includes a driven component and a support component disposed on the sliding block and connected to the support plate, for adjusting the supporting force provided to the limiting wheel.

[0018] As a further embodiment of the present invention: the driven component includes an inclined plate fixed to the side wall of the sliding block, and a push rod that abuts against the inclined plate is fixed on the support plate.

[0019] As a further embodiment of the present invention: the support assembly includes a connecting plate fixed on the sliding block, a movable rod slidably mounted on the connecting plate and rotatably connected to the limiting wheel, a limiting ring fixed on the movable rod and engaging with the connecting plate, and a first spring sleeved on the movable rod, the two ends of the first spring engaging with the connecting plate and the limiting wheel respectively.

[0020] As a further embodiment of the present invention: the flexible support mechanism includes a receiving plate fixed to the side wall of the guide sleeve, a first sliding groove is formed on the receiving plate, and a sliding plate is slidably installed in the first sliding groove;

[0021] It also includes a guide component and an elastic component disposed on the sliding plate and connected to the support rod for adjusting the supporting force of the movable plate.

[0022] As a further embodiment of the present invention: the guiding component includes a straight groove, a first inclined groove, and a second inclined groove formed on the sliding plate, wherein the end of the straight groove and the end of the first inclined groove are connected.

[0023] As a further embodiment of the present invention: the elastic component includes a first movable ring and a second movable ring that slide along the axial direction of the support rod. A first limiting post is fixed on the first movable ring and slides into the straight groove and the first inclined groove. A second limiting post is fixed on the second movable ring and slides into the second inclined groove. A second spring is sleeved on the support rod, and the two ends of the second spring abut against the first movable ring and the second movable ring, respectively.

[0024] A feeding method for an oscillating feeder includes the following steps:

[0025] Step 1: Control the movement of the bidirectional translation mechanism according to the width of the material on the conveyor roller;

[0026] Step 2: The bidirectional translation mechanism drives the clamping mechanism to move, so as to control the limit plate to abut against the side wall of the material, and limit the upper and lower sides of the material by means of the limit wheels;

[0027] Step 3: When the material shifts and causes the limiting plate and limiting wheel to move, the flexible support mechanism moves through the movable plate;

[0028] Step 4: Under the action of the flexible support mechanism, adjust the support force on the movable plate, and adjust the force on the limit wheel through the clamping mechanism to guide the material back to its correct position.

[0029] Compared with the prior art, the beneficial effects of the present invention are: when the material on the conveying roller deviates, the present application can push the limiting plate and the limiting wheel to move under the action of the material deviation force, thereby driving the movable plate to move through the clamping mechanism. The clamping mechanism will adaptively adjust the clamping force of the limiting wheel on the material. At the same time, under the action of the movable plate, the movement of the flexible support mechanism is controlled so as to adjust the support force of the limiting plate on the material through the movable plate, thereby guiding the material to return to the correct position.

[0030] By cooperating with the first limiting post and the straight groove and the first inclined groove, and with the second limiting post and the second inclined groove, the elastic potential energy of the second spring can be slowly increased in the early stage of material swaying when the material is thinner. This prevents the side wall of the material from making hard contact with the limiting plate when the clamping force provided by the limiting wheel is small, which would cause the material side to curl or deform due to friction. At the same time, during swaying, the clamping force of the limiting wheel on the material can be increased by cooperating with the inclined plate and the push rod, so as to distribute the material swaying force to the limiting wheel and ensure that the force between the material and the limiting plate is always kept within a certain range. When the swaying amplitude increases, the second spring can be quickly compressed to counteract the material swaying force and guide the material back to the correct feeding position.

[0043] The technical solutions of the embodiments 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0045] Please see Figures 1-11 In this embodiment of the invention, a swaying feeder includes:

[0046] Workbench 1, and slide rail 101 fixed on workbench 1. Feeding table 2 is slidably installed on slide rail 101. Fixed plates 5 are symmetrically arranged on feeding table 2. Conveying rollers are rotatably installed on fixed plates 5.

[0047] Also includes:

[0048] Gear 4 is rotatably mounted on workbench 1, and a rack plate 3 that meshes with gear 4 is fixed at the bottom of feeding table 2;

[0049] A bidirectional translation mechanism is provided on a fixed plate 5, including a movable plate 14 and a limiting plate 15 fixed on the movable plate 14. The movable plate 14 is provided with a clamping mechanism, which includes symmetrically arranged limiting wheels 19.

[0050] A flexible support mechanism is provided on the bidirectional translation mechanism. When the limiting wheel 19 is subjected to force, the flexible support mechanism can adjust the support force on the limiting wheel 19 through the movable plate 14 and the clamping mechanism.

[0051] Specifically, when feeding strip materials such as aluminum or steel strips, the material needs to be wound around the conveyor rollers. Under the action of gear 4 and rack 3, the feeding table 2 is controlled to move to the designated position. At this time, under the action of the bidirectional translation mechanism, the distance between the two limiting plates 15 is adjusted according to the width of the material, so that the sidewall of the material abuts against the limiting plates 15. The limiting wheels 19 limit the two sides of the material. Under the dual action of the limiting plates 15 and the limiting wheels 19, the material can be guaranteed to a certain extent not to deviate during feeding. If the material deviates during feeding due to external force or improper operation, the force of the material deviation will be used to prevent this deviation. When the limit plate 15 and the limit wheel 19 are moved, the clamping mechanism drives the movable plate 14 to move. The clamping mechanism will adaptively adjust the clamping force of the limit wheel 19 on the material. At the same time, under the action of the movable plate 14, the movement of the flexible support mechanism is controlled so that the support force of the limit plate 15 on the material is adjusted by the movable plate 14, thereby guiding the material back to the correct position. If the material swings too much, the limit wheel 19 can provide sufficient clamping force to prevent the material from deforming due to excessive contact force with the limit plate 15. Under the action of the flexible support mechanism, the thrust on the movable plate 14 is rapidly increased, thereby further limiting the material swing and guiding the material back to the correct position.

[0052] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 9 The bidirectional translation mechanism includes a bidirectional lead screw 6 rotatably mounted on the fixed plate 5. A symmetrically arranged threaded sleeve 7 is threadedly connected to the bidirectional lead screw 6. A support plate 12 and a guide rail 701 are fixed to the side wall of the threaded sleeve 7. A support rod 13 is fixed to the support plate 12. The support rod 13 and the guide rail 701 are slidably connected to the movable plate 14. The bidirectional translation mechanism also includes a guide post 8 fixed to the fixed plate 5. A guide sleeve 9 slides axially on the guide post 8. The guide sleeve 9 is fixedly connected to the threaded sleeve 7.

[0053] In detail, a set of conveyor rollers is set on each side of the feeding platform 2. The material belt is installed on one of the conveyor rollers away from the processing equipment, and after being guided by the adjacent conveyor roller, it passes through the feeding platform 2. Then, after being guided by the other two symmetrical conveyor rollers, the material belt is conveyed into the processing equipment. Through the secondary guidance and positioning method, it can be ensured that the material belt will not deviate. Therefore, when the material is wrapped around the conveyor roller for feeding, in order to prevent the material from deviating during the conveying process and causing errors in subsequent processing, it is necessary to guide and limit the material on both sides to avoid the material from deviating.

[0054] Two limiting plates 15 are provided, and a groove is formed on the side away from the movable plate 14. The groove is trapezoidal, and the opening size is largest on the side away from the movable plate 14. Therefore, the trapezoidal groove can accommodate materials of different thicknesses. In the initial state, under the action of the flexible support mechanism, the movable plate 14 is located at the end of the stroke of the guide rail 701 near the material. Under the action of the bidirectional screw 6, the distance between the two threaded sleeves 7 is maximized, so that the distance between the two movable plates 14 is maximized. When it is necessary to limit the material, the bidirectional screw 6 rotates, driving the two threaded sleeves 7 to move, thereby driving the guide sleeve 9 to slide along the axial direction of the guide post 8. The guide sleeve 9 and the guide post 8 have a guiding function, which can ensure that the threaded sleeve 7 slides along the axial direction of the bidirectional screw 6, and the two threaded sleeves 7 move towards each other.

[0055] The threaded sleeve 7 also drives the support plate 12 and the guide rail 701 to move synchronously, thereby driving the support rod 13 to move, which in turn causes the movable plate 14 to move, adjusting the distance between the two limiting plates 15. At the same time, the movable plate 14 also drives the limiting wheel 19 to move through the clamping mechanism. When the trapezoidal groove formed on the limiting plate 15 fits into the side wall of the material and abuts against the side wall of the material, it can adapt to materials of different thicknesses under the guidance of the trapezoidal groove, and ensure that the material is in the middle position of the trapezoidal groove. At this time, under the action of the clamping mechanism, the limiting wheel 19 abuts against the upper and lower sides of the material. With the double cooperation of the limiting plate 15 and the limiting wheel 19, it can be ensured that the material will not easily deviate during the feeding process.

[0056] Preferably, since the trapezoidal groove is designed as an isosceles trapezoid, it can gradually guide the material to move when the material comes into contact with the inclined surface of the trapezoidal groove, so as to center the material. In addition, the trapezoidal groove is designed to gradually narrow, so that the trapezoidal groove can smoothly fit onto the side wall of the material until both inclined surfaces of the trapezoidal groove come into contact with the side wall of the material, thereby achieving the effect of adapting to materials of different thicknesses.

[0057] Please see Figures 4-10The clamping mechanism includes a second sliding groove 1401 formed on the movable plate 14 and symmetrically arranged, in which a sliding block 16 is slidably installed; it also includes a driven component and a supporting component disposed on the sliding block 16 and connected to the support plate 12, for adjusting the supporting force provided to the limiting wheel 19. The driven component includes an inclined plate 24 fixed to the side wall of the sliding block 16, and a push rod 25 fixed on the support plate 12 that abuts against the inclined plate 24. The supporting component includes a connecting plate 17 fixed on the sliding block 16, and a movable rod 18 slidably installed on the connecting plate 17 and rotatably connected to the limiting wheel 19. A limiting ring 1801 fixed on the movable rod 18 that abuts against the connecting plate 17 is fixed thereon. A first spring 20 is sleeved on the movable rod 18, and the two ends of the first spring 20 abut against the connecting plate 17 and the limiting wheel 19, respectively.

[0058] Please see Figure 4 , Figures 6-11 The flexible support mechanism includes a receiving plate 10 fixed to the side wall of the guide sleeve 9, on which a first sliding groove 1001 is formed, and a sliding plate 11 is slidably installed. It also includes a guide assembly and an elastic assembly disposed on the sliding plate 11 and connected to the support rod 13, for adjusting the supporting force of the movable plate 14. The guide assembly includes a straight groove 1101, a first inclined groove 1102, and a second inclined groove 1103 formed on the sliding plate 11. The end of the straight groove 1101 and the end of the first inclined groove 1102 are connected to each other. The end of 102 is connected. The elastic component includes a first movable ring 21 and a second movable ring 22 that slide along the axial direction of the support rod 13. A first limiting post 2101 that slides and engages with the straight groove 1101 and the first inclined groove 1102 is fixed on the first movable ring 21. A second limiting post 2201 that slides and engages with the second inclined groove 1103 is fixed on the second movable ring 22. A second spring 23 is sleeved on the support rod 13. The two ends of the second spring 23 abut against the first movable ring 21 and the second movable ring 22, respectively.

[0059] Please see Figure 5 Furthermore, the first movable ring 21 is fixedly connected to the movable plate 14, the movable rod 18 passes through the connecting plate 17, a keyway is formed on the through hole on the connecting plate 17, and a key that mates with the keyway is fixed on the outer circumference of the movable rod 18. With the cooperation of the keyway and the key, the movable rod 18 can only slide along the axial direction of the through hole and will not deflect, ensuring that the rotation direction of the limit wheel 19 is consistent with the pulling and feeding direction of the material, so as to ensure that the limit wheel 19 will not generate frictional resistance when feeding the material;

[0060] Please see Figure 5In the initial state, the two limiting wheels 19 abut against each other, and the limiting ring 1801 abuts against the connecting plate 17, making the distance between the limiting wheels 19 and the connecting plate 17 the largest. The extension of the first spring 20 in its natural state is greater than this distance. Therefore, the first spring 20 is in a pre-compressed state and always provides the two limiting wheels 19 with a pushing force in the direction of mutual approach. Thus, the sliding block 16 is located at the end of the stroke on one side of the second slide groove 1401, and the distance between the two sliding blocks 16 is the largest. At this time, the force between the limiting wheel 19 and the material is the smallest, ensuring that the limiting wheel 19 will not affect the normal feeding of the material, nor will the material surface be damaged due to rolling friction.

[0061] Please see Figure 11 The distance between the first movable ring 21 and the second movable ring 22 is the largest, so that the first limiting post 2101 is located at the end of the stroke of the straight groove 1101 away from the first inclined groove 1102, and the second limiting post 2201 is located at the end of the stroke of the second inclined groove 1103 away from the first inclined groove 1102. The extension of the second spring 23 in its natural state is greater than the maximum distance between the first movable ring 21 and the second movable ring 22. Therefore, the second spring 23 is in a pre-compressed state and always provides the first movable ring 21 and the second movable ring 22 with a thrust to move in the direction away from each other. Under the action of the first limiting post 2101 and the straight groove 1101, it can be ensured that the position of the sliding plate 11 will not change. At the same time, under the action of the thrust, the distance between the movable plate 14 and the push rod 25 is the largest. At this time, the inclined end of the inclined plate 24 away from the sliding block 16 abuts against the push rod 25.

[0062] When the trapezoidal groove of the limiting plate 15 abuts against the side wall of the material, it can limit the swaying of the material to a certain extent. However, if the material is deviated due to external force or improper operation, if the material itself is thin, the extension of the second spring 23 is at its maximum in the initial stage of swaying, and the thrust provided to the limiting plate 15 is small. The two limiting wheels 19 have a certain clamping force. Therefore, when the material moves laterally, the connecting plate 17 is driven to move through the limiting wheel 19, which in turn drives the movable plate 14 to move through the sliding block 16, ensuring that the force between the side wall of the material and the limiting plate 15 is not too large.

[0063] When the sliding block 16 moves, it will also drive the inclined plate 24 to move. As the distance between the inclined plate 24 and the push rod 25 decreases, under the action of the inclined surface of the inclined plate 24 and the push rod 25, the two sliding blocks 16 slide radially along the second slide groove 1401 and move toward each other, thereby reducing the distance between the two connecting plates 17. Since the position of the limiting wheel 19 does not change, the first spring 20 will be compressed, thereby increasing the clamping force of the limiting wheel 19 on the material.

[0064] When the movable plate 14 moves, it also controls the first movable ring 21 to slide along the axial direction of the support rod 13 and move towards the direction of the second movable ring 22, so that the first limiting post 2101 slides along the straight groove 1101. The position of the sliding plate 11 will not change. Therefore, the second spring 23 is slowly compressed. If the material swing amplitude is small, when the force acting on the material disappears, the second spring 23 is elastically released and controls the movable plate 14 to reset, so as to control the material to return to the correct position through the limiting wheel 19 and the limiting plate 15.

[0065] If the material swings significantly, the first limiting post 2101 will disengage from the straight groove 1101 and enter the first inclined groove 1102. Under the action of the first limiting post 2101 and the first inclined groove 1102, the sliding plate 11 slides along the first sliding groove 1001 and moves towards the guide sleeve 9, thereby driving the second inclined groove 1103 to move. Under the action of the second inclined groove 1103 and the second limiting post 2201, the second movable ring 22 moves towards the first movable ring 21. In response, the first movable ring 21 and the second movable ring 22 move synchronously and move towards each other, so that the second spring 23 is quickly compressed, thereby further increasing the thrust on the movable plate 14 to overcome the influence of the force on the material and guide the material to reset.

[0066] Preferably, through the cooperation of the first limiting post 2101 with the straight groove 1101 and the first inclined groove 1102, and the cooperation of the second limiting post 2201 with the second inclined groove 1103, the elastic potential energy of the second spring 23 can be slowly increased in the early stage of the thin material swaying. This prevents the side wall of the material from making hard contact with the limiting plate 15 when the clamping force provided by the limiting wheel 19 is small, which would cause the material side to curl or deform due to friction. At the same time, during swaying, the cooperation of the inclined plate 24 and the push rod 25 can increase the clamping force of the limiting wheel 19 on the material, so as to distribute the material swaying force to the limiting wheel 19 and ensure that the force between the material and the limiting plate 15 is always kept within a certain range. When the swaying amplitude increases, the second spring 23 can be quickly compressed to counteract the material swaying force and guide the material back to the correct feeding position.

[0067] A feeding method for an oscillating feeder includes the following steps:

[0068] Step 1: Control the movement of the bidirectional translation mechanism according to the width of the material on the conveyor roller;

[0069] Step 2: The bidirectional translation mechanism drives the clamping mechanism to move, so as to control the limit plate 15 to abut against the side wall of the material, and limit the upper and lower sides of the material through the limit wheel 19;

[0070] Step 3: When the material shifts and causes the limiting plate 15 and the limiting wheel 19 to move, the flexible support mechanism is driven to move through the movable plate 14;

[0071] Step 4: Under the action of the flexible support mechanism, adjust the support force on the movable plate 14, and adjust the force on the limit wheel 19 through the clamping mechanism to guide the material back to the correct position.
