Description

Technical Field

[0001] This application relates to the field of transportation equipment, and in particular to a coil automatic feeding device. Background Art

[0002] During the processing of some parts, the raw materials used are in the form of coils. During processing, it is necessary to support the raw materials, and then traction is applied to the starting end of the raw materials, so that the raw materials gradually roll and achieve the purpose of discharging.

[0003] After the raw materials are used up, new raw materials need to be replaced. During replacement, usually, the new coil is manually placed on the empty roller shaft, and then the leading end of the new raw material is pulled to the processing position, thus completing the coil replacement step of the raw materials.

[0004] However, a large number of manual operations result in low replacement efficiency and reduced work efficiency. Summary of the Invention

[0005] In order to improve the coil replacement efficiency, this application provides a coil automatic feeding device.

[0006] The coil automatic feeding device provided by this application adopts the following technical solutions: A coil automatic feeding device includes a support frame. A plurality of support rollers for supporting coils are provided on the support frame. A feeding box is provided on the side of the support roller away from the support frame. The feeding box has openings on both sides, and the internal width only allows one coil to move. A conveying mechanism for conveying the coil is provided on one side of the feeding box.

[0007] By adopting the above technical solutions, a plurality of support rollers can support a plurality of coils at the same time. When the coil on one of the support rollers is used up, it is quickly continued by the coils on other support rollers, thereby maintaining the continuous production. At the same time, the coil in the feeding box moves from the opening and reaches the conveying mechanism, and the conveying mechanism moves the coil to the support roller without a coil, reducing manual operation and improving the coil replacement efficiency.

[0008] Optionally, the conveying mechanism includes a base. A limiting plate is provided on the base. The limiting plate includes a side baffle opposite to the opening of the feeding box and a front baffle parallel to the side wall of the feeding box. A displacement assembly for conveying the coil is provided below the limiting plate.

[0009] By adopting the above technical solutions, the coil rolls out through the opening of the feeding box and abuts against the side baffle along the front baffle, so that the position of the coil is restricted. Then, the displacement assembly drives the coil to move to the support roller.

[0010] Optionally, the displacement component includes a first slider slidably connected to the base. A first lead screw is rotatably connected to the base and passes through the first slider. A second slider is slidably connected above the first slider, and the sliding direction of the second slider is horizontally perpendicular to the sliding direction of the first slider. A second lead screw for driving the second slider to move is provided on the first slider. A third slider is slidably connected to the second slider and moves in the vertical direction. A positioning member for restricting the position of the coil is provided above the third slider.

[0011] By adopting the above technical solution, when the coil moves above the third slider, the positioning member restricts the position of the coil. Then the third slider descends, the second lead screw drives the second slider to move, and the first lead screw drives the first slider to move, so that the center of the coil is aligned with the support roller until the support roller passes through the coil. Then the third slider descends, so that the coil is supported by the support roller, and the first slider, the second slider and the third slider return to their original positions.

[0012] Optionally, the positioning member includes a lifting block slidably connected to the upper side of the third slider. Positioning plates are provided on both sides of the lifting block and are inserted into the third slider. A lifting groove for accommodating the lifting block is formed in the third slider. A positioning spring connecting the third slider and the lifting block is provided in the lifting groove. A driving rack is provided at one end of the lifting block located in the lifting groove. A gear is meshed with the driving rack. The gear is rotatably connected to the third slider and is simultaneously meshed with a driven rack. The driven rack is fixedly connected to the corresponding positioning plate.

[0013] By adopting the above technical solution, when the coil moves onto the third slider, the coil presses on the lifting block. The lifting block compresses the spring and drives the driving rack to move. The driving rack drives the gear to rotate, and the gear drives the driven rack to move upward. Thus, the positioning plate moves upward, and the coil is supported by the positioning plate, thereby keeping the position of the coil stable and facilitating the displacement component to drive the coil to move.

[0014] Optionally, a guiding roller is correspondingly arranged on one side of the support roller. The guiding roller is arranged on the support frame. A platform is provided on the side of the guiding roller away from the support roller. A detection component, a hot melting component for connecting the head and tail of the coil, and a fixing component for fixing the end of the coil are sequentially arranged on the platform along the direction away from the guiding roller.

[0015] By adopting the above technical solution, when the end of the previous coil moves to the detection component, the fixing component fixes the end of the coil. At the same time, the head of the next coil moves to the hot melting component and fits against the end of the previous coil. The hot melting component then hot melts and connects the head and tail of the two coils, thereby realizing the connection of the coils.

[0016] Optionally, the detection component includes a limiting rod disposed on the platform. There is a gap between the limiting rod and the platform, and a photoelectric sensor facing the platform is provided on the limiting rod.

[0017] By adopting the above technical solution, the coil passes through the gap between the limiting rod and the platform, and the photoelectric sensor detects whether the end of the coil reaches the limiting rod.

[0018] Optionally, the fixing component includes a fixing rod disposed above the platform. A driving member for driving the fixing rod to move up and down is provided on the platform. A pressing block is inserted on the side of the fixing rod facing the platform, and a compression spring is provided between the pressing block and the fixing rod.

[0019] By adopting the above technical solution, when the photoelectric sensor detects the end of the previous coil, the driving member drives the fixing rod to move towards the platform side until the pressing block presses the coil on the platform and the compression spring is compressed, so that the frictional force component received by the coil increases, thereby enabling the coil to gradually stop moving and avoiding the possibility of damage to the coil caused by suddenly stopping the coil.

[0020] Optionally, the hot melt component includes a lower pressing plate disposed on the platform. An upper pressing plate opposite to the lower pressing plate is provided above the lower pressing plate. Resistance wires are provided inside both the lower pressing plate and the upper pressing plate. A plurality of grooves are formed on the lower pressing plate, and convex blocks corresponding to the grooves are provided on the upper pressing plate. Blowing heads are further provided on the platform on both sides of the lower pressing plate.

[0021] By adopting the above technical solution, when the heads and tails of two coils are joined together, the upper pressing plate presses the joint of the heads and tails of the coil on the lower pressing plate. At this time, the resistance wires heat up, thereby melting the heads and tails of the coil together. Subsequently, the upper pressing plate moves up, and at this time, the blowing heads blow air to cool the hot melt part, so that the hot melt part can quickly cool and solidify.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: When the coil on one support roller is used up, it is quickly continued by the coil on other support rollers, thereby maintaining the continuous production. At the same time, the coil in the feeding box moves from the opening and reaches the conveying mechanism, and the conveying mechanism moves the coil to the support roller without a coil, reducing manual operation and improving the coil replacement efficiency; When the end of the previous coil moves to the detection component, the fixing component fixes the end of the coil. At the same time, the head of the next coil moves to the hot melt component and fits with the end of the previous coil. The hot melt component then hot melt connects the heads and tails of the two coils, thereby realizing the continuation of the coil. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] The following further elaborates on the present application with reference to the accompanying drawings.

[0029] An embodiment of the present application discloses an automatic coil feeding device. Referring to Figure 1 , an automatic coil feeding device includes a support frame 1, on which two support rollers 11 for supporting the coil are installed. On the side of the support roller 11 away from the support frame 1, there is a feeding box 2. On both sides of the feeding box 2, there are openings 21, and the internal width only allows one coil to move. The bottom surface inside the feeding box 2 is inclined so that the coil can roll out from the opening 21 on one side. On one side of the feeding box 2, there is a conveying mechanism 3 for transporting the coil. Among them, a limiting member is provided at the opening 21 on the side where the coil rolls out. The limiting member includes a rotating plate 22 provided at the opening 21 of the feeding box 2. One end of the rotating plate 22 is rotatably connected to the feeding box 2, and a limiting block 23 for supporting the rotating plate 22 is abutted against the lower side of the other end. The limiting block 23 is fixed on the feeding box 2.

[0030] Multiple support rollers 11 can support multiple coils simultaneously. When the coil on one of the support rollers 11 is used up, it is quickly continued by the coils on other support rollers 11, thereby maintaining the continuous production. The coil enters the feeding box 2 through the opening 21 on one side of the feeding box 2, so that multiple coils are stored in the feeding box 2. Subsequently, the rotating plate 22 is opened, and the coil rolls out from the opening 21 on the other side of the feeding box 2 and reaches the conveying mechanism 3. Then, the conveying mechanism 3 moves the coil onto the support roller 11 without a coil.

[0031] The conveying mechanism 3 includes a base 31. A limiting plate is provided on the base 31. The limiting plate includes a side baffle 32 opposite to the opening 21 of the feeding box 2 and a front baffle parallel to the side wall of the feeding box 2. The front baffle includes a back plate 33 fixed on the base 31 and located on the side of the base 31 away from the support roller 11, and multiple front plates 34 fixedly connected to the side baffle 32 and arranged side by side. The back plate 33 and the front plates 34 are located on both sides of the coil and respectively abut against the upper and lower ends of the coil. A displacement component 35 for conveying the coil is provided below the limiting plate. The coil rolls out through the opening 21 of the feeding box 2 and abuts against the side baffle 32 along the front baffle, thereby restricting the position of the coil. Subsequently, the displacement component 35 drives the coil to move onto the support roller 11.

[0032] The displacement component 35 includes a first slider 351 slidably connected to the base 31. A first lead screw is rotatably connected to the base 31 and passes through the first slider 351. The first lead screw is threadedly connected to the first slider 351. At the same time, a guide rod parallel to the first lead screw is also fixed on the base 31. The guide rod passes through the first slider 351 and is slidably connected to the first slider 351.

[0033] A second slider 352 is slidably connected above the first slider 351. The sliding direction of the second slider 352 is horizontally perpendicular to the sliding direction of the first slider 351. A second lead screw is rotatably connected to the first slider 351. The second lead screw passes through the second slider 352 and is threadedly connected to the second slider 352.

[0034] A third slider 353 that moves in the vertical direction is slidably connected to the second slider 352. An electric telescopic rod is installed on the second slider 352 and is simultaneously connected to the third slider 353. A positioning member 36 for restricting the position of the coil is provided above the third slider 353.

[0035] When the coil moves above the third slider 353, the positioning member 36 restricts the position of the coil. Subsequently, the third slider 353 descends, the second lead screw drives the second slider 352 to move, and the first lead screw drives the first slider 351 to move, so that the center of the coil is aligned with the support roller 11. Until the support roller 11 passes through the coil, then the third slider 353 descends, so that the coil is supported by the support roller 11, and the first slider 351, the second slider 352, and the third slider 353 return to their original positions.

[0036] The positioning member 36 includes a lifting block 361 slidably connected to the upper side of the third slider 353. The top end of the lifting block 361 is set in an "m" shape. Positioning plates 362 inserted into the third slider 353 are provided on both sides of the lifting block 361. A lifting groove for accommodating the lifting block 361 is formed in the third slider 353. A positioning spring 363 connecting the third slider 353 and the lifting block 361 is provided in the lifting groove. A driving rack 364 is provided at one end of the lifting block 361 located in the lifting groove. A gear 365 meshes with the driving rack 364. The gear 365 is rotatably connected to the third slider 353 and simultaneously meshes with a driven rack 366. The driven rack 366 is fixedly connected to the corresponding positioning plate 362.

[0037] When the coil moves onto the third slider 353, the coil moves along the inclined surface at the top end of the lifting block 361 to the recess of the lifting block 361, so that the coil presses on the lifting block 361. The lifting block 361 descends and compresses the positioning spring 363, and drives the driving rack 364 to move. The driving rack 364 drives the gear 365 to rotate, and the gear 365 drives the driven rack 366 to move upward. Thus, the positioning plate 362 moves upward, and both sides of the coil are supported by the positioning plates 362, maintaining the stable position of the coil.

[0038] A guiding roller 12 is correspondingly arranged on one side of the supporting roller 11. The guiding roller 12 is arranged on the support frame 1. A platform is provided on the side of the guiding roller 12 away from the supporting roller 11. A detection assembly 4, a hot melting assembly 6 connecting the head and tail ends of the coil, and a fixing assembly 5 for fixing the end of the coil are sequentially arranged on the platform along the direction away from the guiding roller 12.

[0039] When the end of the previous coil moves to the detection assembly 4, the fixing assembly 5 fixes the end of the coil. At the same time, the head end of the next coil bypasses the corresponding guiding roller 12 and moves to the hot melting assembly 6, and fits with the end of the previous coil. Subsequently, the hot melting assembly 6 hot melts and connects the head and tail ends of the two coils, thereby realizing the continuation of the coil. Among them, the head end of each coil can be pre - adhered to the corresponding guiding roller 12, so as to facilitate the unwinding of the subsequent coil for use.

[0040] The detection assembly 4 includes a limiting rod 41 installed on the platform. A gap is provided between the limiting rod 41 and the platform. The coil passes through the gap. A photoelectric sensor 42 facing the platform is installed on the limiting rod 41. The coil passes through the gap between the limiting rod 41 and the platform, and the photoelectric sensor 42 detects whether the end of the coil reaches the limiting rod 41.

[0041] The fixing component 5 includes a fixing rod 51 disposed above the platform. A driving member for driving the fixing rod 51 to move up and down is installed on the platform. A pressing block 52 is inserted on the side of the fixing rod 51 facing the platform. A pressing spring 53 for connecting the two is provided between the pressing block 52 and the fixing rod 51. When the photoelectric sensor 42 detects the end of the previous coil, the driving member drives the fixing rod 51 to move towards the platform side until the pressing block 52 presses the coil on the platform and the pressing spring 53 is compressed, so that the frictional force component received by the coil increases, thereby enabling the coil to gradually stop moving.

[0042] The hot-melting component 6 includes a lower pressing plate 61 installed on the platform. An upper pressing plate 62 opposite to the lower pressing plate 61 is provided above the lower pressing plate 61. Resistance wires are provided inside both the lower pressing plate 61 and the upper pressing plate 62. A plurality of grooves 611 are formed on the lower pressing plate 61, and convex blocks 621 corresponding to the grooves 611 are provided on the upper pressing plate 62. Air blowing heads are also provided on the platform on both sides of the lower pressing plate 61 (the air blowing heads are not shown in the figure), and a driving member for driving the upper pressing plate 62 to move up and down. The driving member is a hydraulic cylinder.

[0043] When the heads and tails of two coils are joined together, the upper pressing plate 62 presses the joined part of the heads and tails of the coil on the lower pressing plate 61. At this time, the resistance wire generates heat, thereby melting the heads and tails of the coil together. Subsequently, the upper pressing plate 62 moves up. At this time, the air blowing heads blow air to cool the hot-melted part, so that the hot-melted part can quickly cool and solidify.

[0044] The implementation principle of an automatic coil feeding device according to an embodiment of the present application is as follows: When the photoelectric sensor 42 detects that a coil is used up to the end, the fixing component 5 fixes the end of the coil. Subsequently, the head of another coil on the guiding roller 12 is passed through the gap and joined to the end of the previous coil. The driving member drives the upper pressing plate 62 to descend and presses the head and tail coils tightly on the lower pressing plate 61. The upper pressing plate 62 and the lower pressing plate 61 are heated to melt the coil. After the upper pressing plate 62 and the lower pressing plate 61 are separated, the air blowing heads cool the hot-melted part of the coil, so that the coil can be conveyed as soon as possible. Subsequently, a coil in the feeding box 2 is moved to the conveying mechanism 3, and the conveying mechanism 3 moves the new coil to the empty supporting roller 11.

[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
