Description

Technical Field

[0001] The present invention relates to the technical field of automated coil production, and in particular to automated coil unbinding equipment. Background Art

[0002] During the coil production process, the coils will be connected end to end and entangled with each other, especially magnetically controlled coils and spiral springs, as well as similar coils with a certain elasticity and a circular tubular structure that is spirally wound in circles and has gaps on the side walls. During production and storage, it is very easy for them to be connected end to end and entangled with each other.

[0003] Due to the production process of this coil, the production process is continuously moving backward and rotating in a spiral, so that the wire becomes a spiral cylindrical coil, and its structure is the same as that of a coil spring.

[0004] After this type of coil is produced, a large number of coils will be connected end to end and entangled with each other. During the automated production process, the production line will also be designed to push and move backward in sequence, which will also cause some coils to be entangled with each other end to end in the shape of long rods. This kind of wound coil needs to be untied before it can be packaged normally.

[0005] The untying operation of this coil is currently done manually. The coils connected at both ends to form a long strip are clamped, and a single coil at the end is held and rotated continuously until the coil at the end is separated from the coil wound into a long rod. The single coil is then stored and placed to complete the untying operation of the coil. On the production line, this manual operation cannot be automated, and the production line is interrupted. It is also difficult to achieve automated dust-free production in a closed factory. In addition, this untying operation is time-consuming and labor-intensive, and the efficiency is too low. One coil is untied at a time, and the speed of manual rotation is limited by the arm's flipping angle, and the speed of arm flipping and untying is also very slow.

[0006] Based on this, the present invention designs an automatic coil unbinding device to solve the above problems. Summary of the Invention

[0007] The object of the present invention is to provide an automatic unbinding device for coils, which can guide and convey the long rod coils wound at the ends through a plurality of neatly arranged conveying tubes through this device, and then drive the wound coils through the belt of the unbinding frame to rotate, so as to complete the unbinding operation. In addition, the device is highly efficient, the belt rotates by itself, and a row of coils all in contact with the belt are untied at a time. The conveying tubes can be arranged according to needs, and no manual operation is required throughout the process. After being untied by the belt of the unbinding frame, the untied coils are stored through the receiving tray and automatically stacked and transferred through the transfer suction cup, which is convenient for automated production, efficient, and more convenient for unbinding and storing the coils.

[0008] The present invention is implemented as follows: an automatic coil unbinding device, comprising:

[0009] Conveying pipe, positioning bracket, untying frame, discharging bracket, discharging bracket and transfer suction cup;

[0010] The conveying pipe is a straight pipe with openings at both ends. A positioning groove, an unbinding groove and a discharge stop groove are further provided on the conveying pipe. The positioning groove, the unbinding groove and the discharge stop groove are sequentially provided on the outer wall of the conveying pipe from front to back. The positioning groove and the discharge stop groove are openings provided on the outer wall of the top of the conveying pipe, and the unbinding groove is an opening provided on the outer wall of the bottom of the conveying pipe. A plurality of the conveying pipes are sequentially arranged in parallel on the same plane to form a fence-like pipe arrangement structure.

[0011] The positioning block frame is a flat plate, which can be lifted and arranged above the delivery pipe. The bottom position of the positioning block frame is fixedly locked with multiple positioning plates, and the positioning plates can be lifted and clamped in the positioning grooves of the delivery pipe. Each positioning plate is corresponding to a positioning groove of the delivery pipe and is clamped.

[0012] The discharging stop frame is a straight rod, and the discharging stop frame can be lifted and arranged at the rear end of the conveying pipe. A plurality of discharging baffles are arranged at the bottom of the discharging stop frame, and the discharging baffles can be lifted and closely attached to the rear end of the discharging stop groove. Each of the discharging baffles is positioned in a one-to-one correspondence with a conveying pipe outlet end to block;

[0013] The unbinding frame is a door-shaped frame with an opening at the bottom. A support wheel is provided at each of the four corners of the unbinding frame. A belt is fitted around the outer ring of the unbinding frame. The belt is rotatably fitted around the outer frame of the unbinding frame via the four support wheels.

[0014] The unbinding frame can be lifted and placed on the outside of a plurality of conveying pipes, and the belt at the bottom of the unbinding frame can be detachably engaged in the unbinding groove of the conveying pipe;

[0015] The discharging bracket is a flat plate, which is installed on the discharging guide rail by a linear motor and can be translated. A receiving tray is stably placed on the top of the discharging bracket.

[0016] A material receiving guide rail is further provided above the rear end of the discharging guide rail. The transfer suction cup is a clamp with a vacuum suction cup at the bottom. The transfer suction cup can be lifted and lowered below the material receiving guide rail. The transfer suction cup is slidably mounted on the material receiving guide rail by a linear motor.

[0017] A finished product rack and an empty tray rack are also provided below the material receiving guide rail.

[0018] The beneficial effects of the present invention are as follows: 1. The present invention uses multiple conveying tubes to neatly arrange and convey the coils wound end to end, thereby making the coils travel more orderly. Moreover, the multiple conveying tubes are neatly arranged, so that the rear ends of the coils wound into long rods are aligned, which facilitates guidance and centralized synchronous untying;

[0019] 2. This device has added a blocking plate and a discharge blocking plate, so that the front and rear ends of the coil wound into a long rod can be blocked. The discharge and unbundling rhythm of the coil can be controlled by lifting and releasing and lowering and tightening the blocking plate and the discharge blocking plate. The structure is highly integrated and the movement is smooth and progressive.

[0020] 3. This device uses the positioning plate and the discharge baffle to press and position the two coils at the last end, and then raises the unbinding frame to fit the belt into the unbinding grooves of all conveying pipes, so that the belt can contact and drive the coils closest to the discharge end in all conveying pipes at once, thereby unbinding all the coils in the conveying pipes at once. The unbinding efficiency is high, and manual rotation is not required. In addition, the belt rotates at a high speed, which can drive the coils to rotate quickly and unbind, and multiple coils can be untied at the same time, which is highly efficient.

[0021] 4. This device unties the coils while the receiving tray receives them, and at the same time stores a row of untied coils, and can receive multiple coils on the same receiving tray, which is convenient for storage. The coils are then transported and stored in categories through the transfer suction cup, which is convenient for storage and transportation. The empty trays and the untied finished trays are placed in different areas, which is convenient for subsequent production and makes the coil untying operation convenient and efficient.

DETAILED DESCRIPTION

[0035] See also Figures 1 to 10 As shown, the present invention provides an automatic coil unbinding device. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] In a specific embodiment of the technical solution of the present invention:

[0037] It includes a conveying pipe 1, a positioning stop frame 2, an untying frame 3, a discharging stop frame 4, a discharging bracket 5 and a transfer suction cup 6;

[0038] The conveying pipe 1 is a straight pipe with openings at both ends. A positioning groove 11, an unbinding groove 12 and a discharge stop groove 13 are also provided on the conveying pipe 1. The positioning groove 11, the unbinding groove 12 and the discharge stop groove 13 are sequentially provided on the outer wall of the conveying pipe 1 from front to back. The positioning groove 11 and the discharge stop groove 13 are openings provided on the outer wall of the top of the conveying pipe 1, and the unbinding groove 12 is an opening provided on the outer wall of the bottom of the conveying pipe 1. Multiple conveying pipes 1 are arranged in parallel on the same plane to form a fence-like pipe structure; the positioning groove 11, the unbinding groove 12 and the discharge stop groove 13 all penetrate the outer wall of the conveying pipe 1, and the positioning groove 11 and the unbinding groove 12 are both inwardly concave V-shaped grooves, and the discharge stop groove 13 is an inwardly open semicircular notched groove, and the discharge stop groove 13 is provided at the top of the rear port of the conveying pipe 1;

[0039] The straight-line distance d between the positioning slot 11 and the unbinding slot 12 is the length of a coil, and the straight-line distance between the unbinding slot 12 and the discharge port of the conveying pipe 1 is less than the length of a coil, which is about 1 / 5 of the length d; the length between the positioning slot 11 and the last end of the conveying pipe 1 must be greater than the length of a coil, so the coil pressed by the positioning plate 21 on the positioning slot 11 must be the second-to-last coil. Therefore, the second coil is pressed by the positioning plate 21, and the first coil at the last end is driven to rotate and unbind by the belt 31. The operation is simple, and the positional relationship between the positioning slot 11, the unbinding slot 12 and the discharge blocking slot 13 is set according to the length of the coil. It can be modified or the position of the slot can be changed according to actual needs to ensure that the belt 31 always unbinds the last coil, and the positioning plate 21 always presses the second coil.

[0040] Ensure that the interval between the unbinding slot 12 and the discharge baffle 41 at the rear end of the conveying pipe 1 pressing the work station is less than the length of one coil, that is, the belt 31 is always engaged with the coil at the last end to drive the unbinding. At the same time of unbinding, the discharge baffle 41 is lifted by the discharge bracket 5, so that the last coil has been untied and slides to the rear end and falls into the independent material grid corresponding to the receiving tray 51, completing the collection of the coil. The unbinding process follows the rhythm of the rising and falling and backward pushing of the receiving tray 51 on the discharge bracket 5, and is fully automated. The rhythm is controlled together through the control of the overall equipment. The controller can select the commonly used STM32 microcontroller, which is simple to operate and highly reliable.

[0041] Each conveying pipe 1 is tilted so that it is higher in the front and lower in the back, and the optimal tilt angle of the conveying pipe 1 is 30 degrees, ensuring that the long rod of the wound coil in the conveying pipe 1 can slide continuously backward. Each conveying pipe 1 is the same length, and the outlet ends of each conveying pipe 1 are flush.

[0042] The axes of the positioning slots 11 of each conveying pipe 1 are on the same straight line, the axes of each untying slot 12 also coincide, and the axes of each discharge retaining slot 13 are on the same straight line;

[0043] The axes of the positioning slot 11, the unbinding slot 12 and the discharge blocking slot 13 are parallel to each other;

[0044] The front end opening of the conveying pipe 1 is connected to the raw material feeding device to ensure that the wound coils enter the conveying pipe 1 in sequence.

[0045] The positioning block frame 2 is a flat plate. The positioning block frame 2 can be lifted and arranged above the conveying pipe 1. The bottom position of the positioning block frame 2 is fixedly locked with multiple positioning plates 21. The positioning plates 21 can be lifted and clamped in the positioning grooves 11 of the conveying pipe 1. Each positioning plate 21 corresponds to a positioning groove 11 of the conveying pipe 1.

[0046] Each of the locking shafts 23 and the untying shaft 33 are parallel to each other, and the locking turret 22 and the untying rod 34 do not interfere with each other;

[0047] The locking turret 22 and the unbinding rod 34 on the same side are in the same plane. A driving lever 24 is provided in the gap between the upper ends of the locking turret 22 and the unbinding rod 34. The driving lever 24 is rotated in a vertical plane by a motor, and the upper end of the locking turret 22 or the unbinding rod 34 is lifted by the rotation of the driving lever 24.

[0048] The locking turret 22 and the unbinding rod 34 on the same side are in the same plane, and the rotation paths of the locking turret 22 and the unbinding rod 34 are also in the same plane. A driving lever 24 is provided in the gap between the upper ends of the locking turret 22 and the unbinding rod 34. The driving lever 24 is rotated in a vertical plane by a motor, and the driving lever 24 can be rotated to separate from the locking turret 22 or the upper end of the unbinding rod 34 to rotate and support the support.

[0049] like Figure 3 and Figure 4 As shown, the upper end of the positioning rotating frame 22 is driven by the lever 24 to rotate backward to support, and the positioning rotating frame 22 rotates clockwise along the positioning rotating shaft 23. At this time, the lower end of the positioning rotating frame 22 is rotated and lifted upward, so that the positioning blocking frame 2 is tilted back and no longer fits into the positioning groove 11, thereby lifting the positioning plate 21 to clear the positioning groove 11, so that the coils entangled with each other inside the conveying pipe 1 can slide backward as a whole, but the coils sliding backward will be blocked by the discharge baffle 41 at the rear end outlet of the conveying pipe 1. Figure 4 The coil at the front end of the middle conveying pipe 1 is a coil that is wound together into one.

[0050] The unbinding frame 3 is a door-shaped frame with an opening at the bottom. A support wheel 32 is provided at each corner of the unbinding frame 3. A belt 31 is set on the outer ring of the unbinding frame 3. The belt 31 is rotatably set on the outer frame of the unbinding frame 3 through four support wheels 32; an unbinding rod 34 is fixedly connected to the left and right sides of the unbinding frame 3. The unbinding rod 34 is also a long curved rod in the same plane. An unbinding shaft 33 is provided on the unbinding rod 34. The unbinding rod 34 can be rotatably lifted and installed on the body frame through the unbinding shaft 33;

[0051] The belt 31 is not in contact with the untying frame 3, and the belt 31 is supported and rotated by the support wheel 32, one of which is driven by a motor.

[0052] The unbinding frame 3 is mounted and locked on the lower end of the unbinding rod 34, and the unbinding rod 34 is mounted on the body frame through the unbinding shaft 33. There is an unbinding rod 34 installed on each side of the unbinding frame 3. The unbinding rod 34 is rotatably supported by the unbinding shaft 33. When no external force is applied, the unbinding shaft 33 is pulled by the spring until the belt 31 is no longer in contact with the conveying tube 1.

[0053] The driving lever 24 rotates clockwise, and the driving lever 24 rotates to support the upper end of the untying lever 34, so that the upper end of the untying lever 34 is pushed forward. At this time, the untying lever 34 rotates counterclockwise around the untying shaft 33, and the lower end of the untying lever 34 is lifted upward, so that the untying frame 3 rises. At this time, the belt 31 at the bottom of the untying frame 3 is engaged with the untying groove 12, thereby driving the coil inside the conveying tube 1 to rotate, thereby completing the adjacent coil untying operation, and when the untying frame 3 is lowered, the belt 31 is separated from the conveying tube 1, and no longer drives the coil in the conveying tube 1 to rotate, and no longer affects the sliding of the coil in the conveying tube 1 to the rear end.

[0054] The discharging bracket 5 is a flat plate, which is mounted on the discharging guide rail 52 by a linear motor. The receiving tray 51 is stably placed on the top of the discharging bracket 5. There are four vertically arranged bolts on the top of the discharging bracket 5 for positioning. The four bolt protrusions are inserted and positioned with the receiving tray 51, so that the receiving tray is stably placed.

[0055] The discharging retaining frame 4 is a straight rod, which can be lifted and arranged at the rear end of the conveying pipe 1. A plurality of discharging baffles 41 are provided at the bottom of the discharging retaining frame 4. The discharging baffles 41 can be lifted and blocked at the rear end of the discharging retaining groove 13. Each discharging baffle 41 is positioned in a one-to-one correspondence with an outlet end of the conveying pipe 1 to block;

[0056] A lifting device 53 is provided at the bottom of the discharging bracket 5, and the discharging bracket 5 can be lifted and lowered on the discharging guide rail 52 through the lifting device 53, and the lifting device 53 is slid on the discharging guide rail 52; a base plate is provided at the bottom of the lifting device 53 for moving in coordination with the discharging guide rail 52, and the lifting device 53 can be a lifting cylinder or a lifting servo motor to ensure stable lifting and accurate positioning.

[0057] The discharging bracket 5 is further provided with a discharging slide 44 on both sides, and a discharging slide 42 is provided between the discharging slides 44 on both sides; the discharging slide 42 is a square frame structure, and the left and right sides of the discharging slide 42 are vertically slidable inside the discharging slide 44;

[0058] The discharging slide 42 blocks the upward rising path of the discharging bracket 5. A discharging spring 43 is also provided between the discharging slide 42 and the discharging slide seat 44. The discharging stop 4 is stably mounted above the discharging slide 42 horizontally in the left and right directions.

[0059] A material receiving guide rail 61 is further provided above the rear end of the discharge guide rail 52. The transfer suction cup 6 is a fixture with a vacuum suction cup at the bottom. The transfer suction cup 6 can be hoisted and lifted below the material receiving guide rail 61. The transfer suction cup 6 is slidably mounted on the material receiving guide rail 61 by a linear motor.

[0060] A finished product rack 62 and an empty tray rack 63 are also provided below the material receiving guide rail 61; the finished product rack 62 is a stable platform provided horizontally for facilitating stacking of trays filled with separated coils.

[0061] A plurality of empty trays are stacked up and down on the empty tray rack 63 for grabbing and placing by the transfer suction cup 6. At the tray stacking connection 51 above the empty tray rack 63, there are two micro cylinders equipped with ejectors installed on two screw stepper motors. When sucking a tray, they support the next tray to prevent multiple trays from being sucked up at one time.

[0062] The receiving tray 51 can be customized according to the length of the coil. A plurality of empty slots are provided on the receiving tray 51. Each slot can accommodate a coil, effectively avoiding entanglement. In addition, a plurality of empty slots are distributed in a rectangular array on the top of the receiving tray 51, which is convenient for storing the coils that slip off the outlet end of the conveying pipe 1. The unpacking machine 51 is moved to the rear end of the packing box 52, and the unpacking machine 51 is moved to the rear end of the packing box 52, and the unpacking machine 51 is moved to the rear end of the packing box 52.

[0063] It should be noted that:

[0064] 1. This device is only suitable for the coil products produced to be wound and connected in sequence, and this device can untie them in sequence. This device is designed according to the winding method of the magnetic control coil, and does not limit the type of coil. The size of the coil is suitable for the aperture of the conveying pipe 1 of this device and the length relationship between the positioning slot 11, the untying slot 12 and the discharge stop slot 13; 2. The belt 31 of this device needs to be tightened and then untied on the four support wheels 32 outside the frame 3, and the belt 31 needs to be clamped on the support wheel 32 for rotation. At the same time, the support wheel 32 is a commonly used belt tensioning wheel. A groove is set in the middle of the support wheel 32 to limit the rotation and position relationship of the belt 31 to ensure stable belt driving The unbinding frame 3 is movable and its front and rear positions are stable. The unbinding frame 3 is telescopically lifted and retracted by 34. When the unbinding frame 3 is raised, the horizontal frame of the lower belt 31 is just engaged with the unbinding groove 12 of each conveying tube 1. The unbinding groove 12 is provided at the bottom of the conveying tube 1, which is convenient for engaging with the belt 3, thereby conveniently driving the coil in the conveying tube 1 to be untied; 3. The transfer suction cup 6 and the discharging bracket 5 of this device need to be docked with the material tray 51, and the top of the discharging bracket 5 needs to be provided with an anti-slip pad and an anti-slip groove for stable docking with the receiving tray, and it needs to be easy to disengage in the up and down directions, and the discharging bracket 5 and the receiving tray 51 need to be stably clamped in the front and rear directions. This device belongs to the conventional structure of the production line and will not be repeated.

[0065] When the present invention is in use, each mechanism needs to be restored to its initial position, which can be set and adjusted by the STM32 single-chip microcomputer.

[0066] Multiple empty receiving trays 51 need to be stacked up and placed on the empty tray rack 63, and the receiving trays 51 on the finished product rack 62 are all taken away. Then the equipment can be started, and the discharge bracket 5 moves to the rear end of the discharge guide rail 52. The transfer suction cup 6 absorbs an empty receiving tray 51 on the empty tray rack 63 and places the empty receiving tray 51 at the preset position of the discharge bracket 5. At this time, the discharge bracket 5 moves the receiving tray 51 to the front end along the discharge guide rail 52.

[0067] A long rod formed by winding a coil is placed in the conveying tube 1. A spring for resetting is provided at one end of the positioning rotating frame 22 and the untying rod 34. Under the action of the spring, the untying rod 34 generates a pulling force, which forces the untying rod 34 to rotate clockwise, thereby keeping the untying frame 3 and the conveying tube 1 separated. The positioning rotating frame 22 also generates a clockwise rotation tendency under the action of the reset spring, so that when the positioning rotating frame 22 is not subjected to external force, the positioning plate 21 remains pressed downward in the positioning groove 11 to block the position.

[0068] When the driving lever 24 starts to rotate under the action of the motor, the driving lever 24 needs to rotate slowly. The driving lever 24 first drives the positioning rotary frame 22 to rotate counterclockwise along the positioning shaft 24, so that the positioning plate 21 at the lower end of the positioning rotary frame 22 is lifted, and the coil on the positioning groove 11 is no longer blocked by the positioning plate 21. The front end of the conveying pipe 1 is higher than the rear end, forming a 30° angle. The coil that has lost the obstruction slides backward in the conveying pipe 1 until it slides to the rear end outlet of the conveying pipe 1 and is blocked by the discharge baffle 41. The driving lever 24 continues to rotate. At this time, the positioning rotary frame 22 loses the support of the driving lever 24 and returns to its original position. The positioning plate 21 at the bottom of the positioning rotary frame 22 is pressed down into the positioning groove 11, and the second coil in the conveying pipe 1 is pressed and blocked.

[0069] The driving lever 24 continues to rotate clockwise to support the untying rod 34. At this time, the untying rod 34 is supported and rotated clockwise along the untying shaft 33. The lower end of the untying rod 34 is lifted upward, and the untying frame 3 rises accordingly, so that the belt 31 is engaged with the untying groove 12, and a force is applied to the coil in the untying groove 12 to rotate. At this time, the coil at the last end of the conveying tube 1 is driven to rotate by the belt 31, and the last coil rotates, while the second coil is stuck by the positioning plate 21 and cannot rotate. The two coils rotate relative to each other, completing the untying operation.

[0070] When the material receiving tray 51 receives the material, it has been lifted up by the lifting device 53, which makes it more accurate to receive the coil and make it slide into the empty slot. Figure 2 Shown at the top of the receiving tray 51.

[0071] When the material is received, the lifting device 53 descends, and the material receiving plate 51 no longer supports the horizontal rod on the top of the discharge slide 42, and the discharge slide 42 will be pulled downward by the discharge spring 43. The downward pulling force causes the discharge slide 42 to fall back downward, thereby causing the discharge blocking frame 4 to drive the discharge baffle 41 to also descend in height. The discharge baffle 41 blocks the discharge blocking groove 13 at the rear end of the conveying pipe 1, and keeps the discharge baffle 41 blocking the rear end outlet of the conveying pipe, so that the subsequent untied coils cannot fall.

[0072] The lowered discharge bracket 5 will be driven by the servo motor to move backward along the discharge guide rail 52, aligning the empty space slot with the rear end of the conveying pipe 1.

[0073] The driving lever 24 rotates continuously, and the coils are untied one by one, and the discharging bracket 5 will support the receiving tray 51 to move backward continuously, each time moving the spacing of a space slot, to ensure that the receiving tray 51 can continuously use the controlled space slot to receive the coils. When a receiving tray 51 is full, the transfer suction cup 6 absorbs the fully loaded receiving tray 51 to the finished product rack 62, and absorbs an empty receiving tray 51 again and places it on the discharging bracket 5, and performs the untying operation again, and repeats this cycle to automatically untie the coils.

[0074] A position sensor can be installed on the backward moving station of the discharge device 5 to detect whether the receiving tray 51 has been carried to the front end. Once it is carried to the front end, it means that the receiving tray 51 is full. The empty receiving tray 51 can be replaced by the transfer suction cup 6 for carrying. The device has a stable structure, fully mechanized operation, high efficiency, and does not require manual operation.

[0075] It should be noted that the front end of the device refers to the direction in which the raw materials enter, while the rear end refers to the direction in which the coil moves after the untying is completed. In addition, in the description of the present invention, the indicated orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0076] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
