Description

Technical Field

[0001] This invention relates to the field of EVA rubber sheet feeding, and specifically to a method for accurately feeding EVA rubber sheets using a multi-segment swing wheel controlled conveyor platform. Background Technology

[0002] EVA rubber sheets are a multifunctional, high-performance synthetic material widely used in various industries. With technological advancements and increasing market demand, its application scope will continue to expand.

[0003] Currently, in the production process of EVA rubber sheets, after final molding, the sheets are conveyed and unloaded via a swing wheel conveyor platform. However, EVA rubber sheets vary in length during production, and the unloading requirements for different lengths of EVA rubber sheets are different. Common swing wheel conveyor platforms cannot meet the requirements of varying lengths, resulting in inaccurate unloading positions, easy scattering, and the need for manual sorting, which is time-consuming and labor-intensive and cannot meet production needs. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a method for precisely conveying EVA rubber sheets using a multi-segment swing wheel-controlled conveying platform. The method is ingeniously designed, has a reasonable and compact structure, and can meet the precise feeding requirements of EVA rubber sheets of different lengths.

[0005] The technical solution of the present invention:

[0006] A method for precisely conveying EVA rubber sheets using a multi-segment swing wheel controlled conveyor platform, comprising the following specific steps:

[0007] Step 1: First, based on the length of the EVA rubber sheet, set the rotation speed of all the swing wheels on the controller through the human-machine interface; set the Nth swing wheel conveyor platform to be used for unloading; set the time required for the EVA rubber sheet to be unloaded from the inlet to the swing wheel conveyor platform to be T1 seconds, and the waiting time after the equipment swing wheel rotates a certain angle to be T2 seconds.

[0008] Step two: After the balance wheel conveyor platform starts, the controller controls all balance wheels to rotate synchronously, driving the EVA rubber sheet forward.

[0009] When the EVA rubber sheet enters the first set of basic swing wheel conveyor platforms, the photoelectric switch detects the EVA rubber sheet signal and transmits the signal to the controller. At the same time, the EVA rubber sheet passes under the wheel-type rotary encoder. The wheel-type rotary encoder measures the length of the EVA rubber sheet and transmits the length measurement signal to the controller. The controller starts the pre-set feeding thread and feeds the EVA rubber sheet to the Nth swing wheel conveyor platform for feeding. After the EVA rubber sheet advances for T1 seconds, the controller controls the swing wheel of the Nth swing wheel conveyor platform to rotate synchronously at a certain angle, so that the EVA rubber sheet moves to the left or right front direction until it falls into the feeding and receiving part on one side, completing the receiving.

[0010] Step 3: After the Nth balance wheel of the conveyor platform rotates at a certain angle, it waits for T2 seconds before resetting and waiting for the next feeding action.

[0011] The length of the EVA rubber sheet is an extended sheet, which is the length of at least two sets of balance wheel conveying platforms. The time for the extended sheet to pass through at least two sets of balance wheel conveying platforms is T3, which is adjusted by adjusting the rotation speed of the balance wheel. At the same time, there are at least two sets of auxiliary balance wheel conveying platforms for feeding, and the at least two sets of auxiliary balance wheel conveying platforms for feeding synchronously drive the balance wheel movement and the drive motor synchronously controls the balance wheel deflection movement.

[0012] When each set of photoelectric switches detects the EVA rubber sheet leaving the site, and the previous set of photoelectric switches does not detect the EVA sheet, the controller controls the previous set of swing wheel conveyor platforms to reset. At this time, the controller controls the corresponding swing wheel conveyor platform to operate according to the feeding thread set for the EVA rubber sheet. Different feeding threads are set for EVA rubber sheets of different lengths.

[0013] The two or more adjacent sets of basic balance wheel conveying platforms form a whole and rotate synchronously, and the two or more adjacent sets of auxiliary balance wheel conveying platforms form a whole and rotate synchronously.

[0017] The basic balance wheel conveying platform and the auxiliary balance wheel conveying platform have the same structure, both including a housing, several sets of balance wheels, a drive motor, and a connecting rod assembly. Several sets of balance wheels are evenly distributed inside the housing, and the drive motor drives several sets of balance wheels uniformly through a connecting assembly. The controller electrically controls and connects to each drive motor. The balance wheels in the several sets of balance wheels are electric roller balance wheels, and each electric roller balance wheel is electrically connected to the controller through a wire. The drive motor is a servo motor.

[0018] The material receiving section includes a frame, a receiving rack, and a fence. The receiving rack is horizontally inclined at the top of the frame, and the frame is positioned on one or both sides of the swing wheel conveyor platform. The receiving rack is inclined downwards on the side away from the swing wheel conveyor platform. Fences are installed on the side of the receiving rack away from the swing wheel conveyor platform and on its front side. The material receiving section also includes a blower mechanism, which is installed on the side of the frame near the swing wheel conveyor platform. The blower mechanism is located above the receiving rack, and its air outlet faces away from the swing wheel conveyor platform. The blower mechanism includes a blower box and a support arm. A round tube is installed on the inner side of each end of the blower box. The round tube is rotatably connected to the upper end of a support arm, and the lower end of the support arm is rotatably mounted on the frame. A strip-shaped air outlet is provided on the outer side of the blower box. Downward-inclined guide plates are installed on both sides of the swing wheel conveyor platform.

[0019] The frame is designed as an L-shaped frame, comprising a horizontal frame and a vertical frame. The receiving rack is designed as a rectangular frame. One side of the receiving rack is rotatably mounted on the inner side of the vertical frame of the L-shaped frame. The lower end of the other side of the receiving rack is mounted on the horizontal frame via a telescopic part. The front end of the telescopic part is rotatably connected to the lower end of the other side of the receiving rack, and the rear end of the telescopic part is rotatably connected to the inner side of the horizontal frame near the vertical frame.

The controller independently controls at least two sets of basic pendulum conveyor platforms and at least one set of auxiliary pendulum conveyor platforms. One set of platforms can be driven and deflected independently, or multiple adjacent sets can be driven and deflected synchronously. The coordinated operation of multiple pendulum conveyor platforms enables automatic and stable feeding of EVA rubber sheets of different lengths without scattering. The feeding and receiving section features an inclined receiving frame. After the EVA rubber sheets fall onto the inclined frame, they automatically slide towards the edge under the influence of gravity, resulting in orderly stacking and meeting production requirements.

[0030] See attached document Figure 1-5 The multi-segment balance wheel control and conveying platform includes a balance wheel conveying platform 4, a photoelectric switch 10, a wheel-type rotary encoder 50, and a controller 20. The balance wheel conveying platform 4 includes at least two sets of basic balance wheel conveying platforms 401 and at least one set of auxiliary balance wheel conveying platforms 402. The at least two sets of basic balance wheel conveying platforms 401 are connected end-to-end from back to front, and the at least one set of auxiliary balance wheel conveying platforms 402 is also connected to the front side of the foremost basic balance wheel conveying platform 401. Each of the auxiliary balance wheel conveyor platforms 402 is independently controlled by a balance wheel conveyor platform 4. The controller 20 electrically controls and connects at least two sets of basic balance wheel conveyor platforms 401 and at least one set of auxiliary balance wheel conveyor platforms 402. A photoelectric switch 10 is installed on one side of the entrance end of each set of balance wheel conveyor platforms 401, and each photoelectric switch 10 is electrically connected to the controller 20 via wires. A wheel-type rotary encoder 50 is installed above the photoelectric switch 10 of the first set of balance wheel conveyor platforms, and the wheel-type rotary encoder 50 is electrically connected to the controller via wires. The controller 20 also includes a human-machine interface 201, which is electrically connected to the controller 201 via wires.

[0031] The basic balance wheel conveying platform 401 consists of two sets, and the auxiliary balance wheel conveying platform 402 consists of three or four sets.

[0032] The basic balance wheel conveying platform 401 and the auxiliary balance wheel conveying platform 402 have the same structure, both including a housing 4011, several sets of balance wheels 4012, a drive motor 4013, and a connecting rod assembly 4014. Several sets of balance wheels 4012 are evenly distributed within the housing 4011. The drive motor 4013 drives these sets of balance wheels 4012 uniformly through a connecting assembly. The controller 20 electrically controls each drive motor 4013. The balance wheels in the sets of balance wheels 4012 are electric roller balance wheels, and each electric roller balance wheel is electrically connected to the controller 20 through a wire. The drive motor 4013 is a servo motor. The method of using a drive motor to drive the connecting rod assembly to deflect several sets of balance wheels is existing technology, as described in patent CN202020027388.5, and is briefly described in this invention.

[0033] The EVA rubber sheet multi-segment swing wheel control conveyor platform also includes a material receiving section 30, which is installed in front of at least one set of auxiliary swing wheel conveyor platforms 402 or on one or both sides of at least one set of auxiliary swing wheel conveyor platforms 402 and at least two sets of basic swing wheel conveyor platforms 401.

[0034] See attached document Figure 6-9The material receiving section 30 includes a frame 1, a receiving rack 2, and a fence 3. The receiving rack 2 is horizontally inclined at the upper end of the frame 1, and the frame 1 is positioned on one or both sides of the swing wheel conveyor platform 4. The receiving rack 2 is inclined downwards on the side away from the swing wheel conveyor platform 4. Fences 3 are installed on the side of the receiving rack 2 away from the swing wheel conveyor platform 4 and on its front side. The inclined installation of the receiving rack allows the falling EVA rubber sheets to slide downwards under the influence of gravity, where the fences block and arrange them in an orderly manner, eliminating the need for manual sorting, reducing labor intensity, and improving production efficiency. The receiving section of this invention is configured on both sides of the swing wheel conveyor platform, forming two workstations, allowing for simultaneous material receiving from both sides, thus improving material unloading efficiency. The material receiving section also includes a blower mechanism 5, which is installed on the side of the frame 1 closest to the swing wheel conveyor platform 4, above the receiving rack 2, with the blower nozzle facing away from the swing wheel conveyor platform 4. The blower mechanism 5 includes a blower box 51 and a support arm 52. A circular tube is installed on the inner side of each end of the blower box 51. The circular tubes are rotatably connected to the upper end of the support arm 52, and the lower end of the support arm 52 is rotatably mounted on the frame 1. A strip-shaped air outlet 53 is provided on the outer side of the blower box 51. The blower mechanism is designed to assist in blowing the EVA rubber sheet forward, allowing it to fall to the desired position, thus aiding in more stable and neat material falling. The blower box can be rotated relative to the support arm, and the support arm can also be rotated relative to the frame. Due to the damped rotation design, it can rotate under external force and remain stationary when no force is applied, ensuring stable blowing at the adjusted angle. The circular tubes of the blower box are connected by air pipes, and there is also an air input connection at one end, all of which are existing technologies. This invention only provides a simplified description and illustration.

[0035] The frame 1 is designed as an L-shaped frame, comprising a horizontal frame 11 and a vertical frame 12. The receiving rack 2 is designed as a rectangular frame. One side of the receiving rack 2 is rotatably mounted on the inner side of the vertical frame 12 of the L-shaped frame. The lower end of the other side of the receiving rack 2 is mounted on the horizontal frame 11 via a telescopic part 21. The front telescopic end of the telescopic part 21 is rotatably connected to the lower end of the other side of the receiving rack 2, and the rear end of the telescopic part 21 is rotatably connected to the inner side of the end of the horizontal frame 11 closest to the vertical frame 12. The telescopic part is one of a telescopic cylinder, a telescopic hydraulic cylinder, or an electric telescopic cylinder. The receiving rack is designed as an adjustable mounting structure. Through the telescopic movement of the telescopic part, the tilt angle of the receiving rack on the frame can be adjusted to meet the EVA rubber sheet feeding requirements and ensure orderly arrangement. Support feet can be designed under the horizontal frame of the frame for support and fixation.

[0036] The receiving rack 2 is designed with a rectangular frame. Several vertically inverted U-shaped frames 22 are evenly distributed on the upper end of the rectangular frame. A gap 23 is left between adjacent vertically inverted U-shaped frames 22, and the outer opening of the gap 23 faces away from the side of the swing wheel conveying platform 4. Several vertical through holes 24 are evenly designed on the vertically inverted U-shaped frames 22. The distance between two vertical through holes 24 of adjacent vertically inverted U-shaped frames 22 is the same as the distance between two adjacent vertical through holes 24 on each vertically inverted U-shaped frame 22. Several insert rods 31 are installed at the lower end of the fence 3. The distance between adjacent insert rods 31 is also the same as the distance between two adjacent vertical through holes 24 on each vertically inverted U-shaped frame 22. The fence 3 is inserted into the frontmost vertically inverted U-shaped frame 22 from the left and right by insert rods 31, and the fence 3 is inserted into the outermost vertical through hole 24 of adjacent vertically inverted U-shaped frames 22 from the front and back by insert rods 31. The design of the gap 23 and the pluggable design of the fence facilitates the removal of stacked sheets by inserting a forklift through the gap; after removal, the fence can be inserted back. The fence 3 can also be inserted into any of the vertical inverted U-shaped frames 22 in the middle. The middle position of the fence on one side of the receiving rack can be selected according to different sheet sizes, which can divide one side of the receiving rack into two receiving stations. The fence is designed as a rectangular frame with multiple vertical supports in the middle, which is existing technology and is briefly described in this invention. The upper inner sides of the adjacent vertical inverted U-shaped frames 22 are connected by horizontal braces, and a guide rod 25 is installed in the middle of the inner side of the horizontal brace. The guide rod 25 is parallel to the upper end of the vertical inverted U-shaped frame 22. The swing wheel conveyor platform 4 has downwardly inclined guide plates 41 installed on both sides. The guide plate design helps the sheet material to be fed more smoothly and stably. The guide plate is located above the blower mechanism, and the blower mechanism works with the blower to assist in the guiding effect.

[0037] When using the material receiving unit of this invention, the swing wheel conveyor platform sequentially transports EVA rubber sheets to the receiving racks on the left and right sides or one side. When the EVA rubber sheets fall from the swing wheel conveyor platform, they can first be guided by the guide plate. At the same time, the blower mechanism also blows air outward to assist the EVA rubber sheets, which then continue to slide down onto the receiving rack. Under the action of their own gravity and inertia, they slide down along the inclined receiving rack and stop against the outer and front fences, automatically adjusting themselves neatly. This process is repeated to stack the materials. After completion, the outer fence is removed, and a forklift is inserted through the gap set at the top of the receiving rack to lift and remove the stacked EVA rubber sheets. This method is simple and convenient, reduces labor, improves production efficiency, and meets production needs.

[0038] A method for precisely conveying EVA rubber sheets using a multi-segment swing wheel controlled conveyor platform, comprising the following specific steps:

[0039] Step 1: First, based on the length of the EVA rubber sheet, set the rotation speed of all the swing wheels on the controller through the human-machine interface; set the Nth swing wheel conveyor platform to be used for unloading; set the time required for the EVA rubber sheet to be unloaded from the inlet to the swing wheel conveyor platform to be T1 seconds, and the waiting time after the equipment swing wheel rotates a certain angle to be T2 seconds.

[0040] Step two: After the balance wheel conveyor platform starts, the controller controls all balance wheels to rotate synchronously, driving the EVA rubber sheet forward.

[0041] When the EVA rubber sheet enters the first set of basic swing wheel conveyor platforms, the photoelectric switch detects the EVA rubber sheet signal and transmits the signal to the controller. At the same time, the EVA rubber sheet passes under the wheel-type rotary encoder. The wheel-type rotary encoder measures the length of the EVA rubber sheet and transmits the length measurement signal to the controller. The controller starts the pre-set feeding thread and feeds the EVA rubber sheet to the Nth swing wheel conveyor platform for feeding. After the EVA rubber sheet advances for T1 seconds, the controller controls the swing wheel of the Nth swing wheel conveyor platform to rotate synchronously at a certain angle, so that the EVA rubber sheet moves to the left or right front direction until it falls into the feeding and receiving part on one side, completing the receiving.

[0042] Step 3: After the Nth balance wheel of the conveyor platform rotates at a certain angle (between 0 and 90 degrees), it waits for T2 seconds before resetting and waiting for the next feeding action.

[0043] The EVA rubber sheet is an extended sheet, meaning its length is equal to the length of at least two sets of pendulum conveyor platforms. The time it takes for the extended sheet to pass through these platforms is T3, adjusted by regulating the pendulum rotation speed. Simultaneously, at least two auxiliary pendulum conveyor platforms are used for feeding, and these platforms synchronously drive the pendulum's movement, while the drive motor synchronously controls the pendulum's deflection. When each photoelectric switch detects the EVA rubber sheet leaving the platform, and the previous photoelectric switch does not detect the EVA sheet, the controller resets the previous pendulum conveyor platform. The controller then controls the corresponding pendulum conveyor platform based on the feeding thread set for the EVA rubber sheet. Different feeding threads are set for EVA rubber sheets of different lengths. The adjacent two or more sets of basic pendulum conveyor platforms form a single unit and rotate synchronously, as do the adjacent two or more sets of auxiliary pendulum conveyor platforms. A rotary encoder determines the length of the incoming EVA rubber sheet. Based on the length determination, the controller controls multiple sets of swing wheel conveyor platforms to synchronously convey and deflect the EVA rubber sheet, and then convey it to the designated receiving rack at the unloading and receiving section. The length of the receiving rack can be designed according to the length of the EVA rubber sheet. Different lengths of EVA rubber sheets correspond to different lengths of receiving racks, and the unloading threads are also different to meet the requirements of precise unloading.
