[0002] After the steel coil is produced, in order to ensure that the steel coil is not damaged during lifting, transportation and storage, protective materials need to be packaged on the outside of the steel coil and the eye of the coil. The main packaging materials are rust-proof paper, plastic film, eye steel sheet, peripheral steel sheet, inner iron corner protector, outer iron corner protector, circumferential strapping, eye strapping, etc. The main method for placing the eye steel sheet is manual. The prepared eye steel sheet is manually placed into the eye of the steel coil and the eye steel sheet is tightly attached to the inner wall of the eye. Generally, the eye steel sheet is made of galvanized sheet with a thickness of 0.4-0.6mm, and the inner diameter of the eye is generally 610mm or 508mm. If the width of the steel coil is 1200mm, the eye steel sheet is generally 50-100mm smaller than the width of the steel coil, and the weight of the eye steel sheet required is: 3.14*0.61*(1.2-0.1)*0.4 / 1000*7850=6.61kg. When placing manually, you first need to roll about 7kg of rolled steel sheet into a tube, and then put it into the eye. The edges of the thin steel sheet are sharp and the operation is dangerous. It is a dangerous and hard job for the packaging workers.

[0003] With the increase in labor costs and the implementation of intelligent manufacturing, it is required to change the placement method of the coil eye steel skin under the condition of meeting the packaging quality, improve the level of automation and intelligence, and realize the automatic packaging of steel coils. Summary of the invention

[0028] Below, the specific structure of the device for packaging steel coil eye steel skin of the present application is described in detail with reference to the accompanying drawings.

[0029] Figure 1 This is a schematic diagram of the structure of the device of this application in one direction; Figure 2 for Figure 1 The schematic diagram of the structure of the placement machine. Figure 1 , Figure 2 As shown, the device for packaging the eye steel skin of steel coils includes: an unwinder 1 for providing the eye steel skin; a shearing machine 2 for cutting the eye steel skin; and a placing machine 3 for placing the eye steel skin into the eye of the steel coil. The unwinder 1, the shearing machine 2, and the placing machine 3 are arranged horizontally in sequence, and a guide plate 4 for lifting the eye steel skin for its passage is arranged horizontally in the middle. Among them, the unwinder 1 can unwind the eye steel skin of different specifications placed therein, and the unwinder 1 has a transition roller 11, which can transfer the unwinded eye steel skin to the guide plate 4. The eye steel skin can be transported along the guide plate 4, and after passing through the shearing machine 2, it reaches the placing machine 3. When the transported eye steel skin reaches a specified length, the shearing machine 2 can cut the eye steel skin.

[0030] The placement machine 3 includes a winding mechanism 31 for winding and unwinding the eye steel sheet; an auxiliary mechanism 32 for assisting the eye steel sheet to be wound tightly; a vertical moving mechanism 33 for driving the winding mechanism 31 to move vertically; and a horizontal moving mechanism 34 for driving the winding mechanism 31 to move horizontally. Among them, the vertical moving mechanism 33 is composed of a frame 331 and a lifting cylinder 332. The frame 331 is a rectangular parallelepiped frame structure, including a rectangular top plate 331a and a bottom plate 331b horizontally located at the top and bottom, and four support plates 331c located between the top plate 331a and the bottom plate 331b and vertically arranged at the four corners, and there is a certain movable space between each support plate 331c. A lifting cylinder 332 is vertically arranged at the middle position of both ends of the bottom plate 331b along the conveying direction of the eye steel sheet (the direction is designated as the front), and the top of the lifting cylinder 332 is fixedly connected to the connecting part 313 at the middle position of both sides of the following reel seat 311, and the lifting cylinder 332 can push the reel seat 311 to move up and down.

[0031] The horizontal moving mechanism 34 includes a bottom frame 341, two parallel guide rails 342 are arranged in the left and right directions in the bottom frame 341, and a rack 343 is arranged on the inner side of the guide rail 342 along the guide rail 342. Four sliders 344 are arranged at the four corners of the bottom of the bottom plate 331b relative to the guide rail 342, so that the bottom plate 331b and the frame 331 can slide horizontally along the top of the guide rail 342. A translation motor 345 is arranged vertically downward at the left side of the bottom plate 331b between the two guide rails 342, and a driving gear 346 is arranged on the driving shaft of the translation motor 345. The driving gear 346 is meshed with the rack 343, and the translation motor 345 rotates to drive the frame 331 to slide along the guide rail 342.

[0032] The winding mechanism 31 includes a reel seat 311 in a rectangular parallelepiped shape. The reel seat 311 is sized so that it can be placed between four support plates 331c of a frame 331. The length of the reel seat 311 in the front-to-back direction is slightly smaller than the distance between the support plates 331c in that direction, and the length of the reel seat 311 in the left-to-right direction is slightly larger than the width of the frame 331 in that direction, and it slightly extends from between the support plates 331c to the left-to-right direction. A guide wheel 312 is respectively arranged at the upper middle position of the front and rear sides of the reel seat 311 and the downwardly extending position in the middle of the front and rear sides. The four guide wheels 312 are located between the support plates 331c, and the diameter of the guide wheels 312 is adapted to the space between the support plates 331c. The shape of the guide wheels 312 is similar to that of a train wheel. An annular flange 312a is radially arranged on the inner side of the wheel to prevent the wheel from deviating outward from the support plates 331c, so that the reel seat 311 can only move up and down along the support plates 331c. A square boss-shaped connecting portion 313 extends outward from the middle position on both sides of the reel seat 311, and the bottom of the connecting portion 313 is fixedly connected to the top of the above-mentioned lifting cylinder 332, so that the reel seat 311 can be driven to move up and down along the support plate 331c through the lifting cylinder 332.

[0033] A cylindrical reel 314 extends from the middle position on the right side of the reel seat 311, and the left end of the reel 314 passes through the reel seat 311 from the middle position on the right side of the reel seat 311 and has a portion extending from the left side of the reel seat 311, and is provided with a reel sprocket 315. A driving motor 316 is provided on the top of the reel seat 311, and the driving motor 316 extends from the left side of the reel seat 311, and a motor sprocket 317 is provided at the corresponding position of the reel sprocket 315. The motor sprocket 317 is connected to the reel sprocket 315 by a chain transmission, so that the rotation of the driving motor 316 can drive the reel 314 to rotate. The part of the reel 314 extending from the reel seat 311 is evenly distributed with four spirally arranged side by side winding guide plates 318 on the reel 314. The central end of the winding guide plate 318 is fixedly connected to the reel 314. The winding guide plate 318 is wound around the reel 314 for one circle and then continues to extend for a distance. There is a certain space between the winding guide plate 318 and the reel 314, and an opening is formed at the upper part of the reel 314. The opening faces the guide plate 4 so that the steel sheet can enter the winding guide plate 318 through the opening after being sent out on the guide plate 4. An electromagnetic suction cup 319 is respectively arranged at the central end and the top of the opening end of the winding guide plate 318, which is used to absorb the head and tail of the steel sheet.

[0034] The auxiliary mechanism 32 includes a swing arm cylinder 321 arranged on the top of the top plate 331a and extending to the right. The end of the swing arm cylinder 321 is connected to a swing arm 322 through a hinge. The swing arm 322 extends downward for a certain distance and then horizontally extends to the right to the second auxiliary winding guide plate 318 from left to right and then extends downward, and forms a rotating shaft 323 on both sides of the end, and a pressing roller 324 is arranged on each of the rotating shafts 323. Among them, the length ratio of the upper vertical part to the lower vertical part is about 1:2. A support shaft 325 is arranged on the right support plate 331c at the front side of the frame 331. The support shaft 325 is hingedly connected to the horizontal part of the swing arm 322, so that when the swing arm cylinder 321 pushes the upper end of the swing arm 322 to move forward, the pressing roller 324 located at the lower end of the swing arm 322 moves toward the auxiliary winding guide plate 318 and finally presses on the auxiliary winding guide plate 318.

[0035] During operation, the unwinder 1 can unwind the rolled steel sheet and convey it to the guide plate 4 through the transition roller 11. The steel sheet is conveyed forward along the guide plate 4. After the steel sheet is separated from the guide plate 4, it enters the auxiliary winding guide plate 318 through the opening formed on the auxiliary winding guide plate 318 and is spirally conveyed along the auxiliary winding guide plate 318. When the head of the steel sheet reaches the center end of the auxiliary winding guide plate 318, the electromagnetic suction cup 319 at the center end is energized to absorb the head of the steel sheet. The reel 314 drives the motor 316 to rotate, driving the reel 314 to rotate at the same linear speed as the conveying speed of the steel sheet, and winding the steel sheet around the outer side of the auxiliary winding guide plate 318 of the reel 314. At the same time, the swing arm cylinder 321 drives the pressure roller 324 to press on the outer side of the auxiliary winding guide plate 318, so that the steel sheet is wound more tightly on the auxiliary winding guide plate 318. After the uncoiler 1 delivers the specified length of the eye steel sheet, the shearing machine 2 works to cut the eye steel sheet on the guide plate 4, the uncoiler 1 stops delivering the eye steel sheet, and the reel 314 continues to rotate to wind the remaining eye steel sheet on the guide plate 4 outside the auxiliary winding guide 318. At this time, the electromagnetic suction cup 319 at the open end of the auxiliary winding guide 318 is energized to absorb the tail of the eye steel sheet, completing the winding of the eye steel sheet, and the swing arm cylinder 321 drives the swing arm 322 and the pressure roller 324 away from the reel 314. The lifting cylinder 332 works to adjust the height of the reel seat 311 so that the reel 314 is facing the central axis of the eye of the steel coil located in the waiting position. The translation motor 345 works to drive the frame 331 to slide horizontally to the right along the guide rail 342 so that the reel 314 is inserted into the eye of the steel coil. At this time, the positions of the swing arm 322 and the pressure roller 324 will not affect the insertion of the reel 314 into the eye of the steel coil. When the eye reaches the specified position, the electromagnetic suction cups 319 at the center end and the open end are powered off and stop working. The steel skin of the eye stretches radially toward the eye under the action of its own elasticity. At the same time, the reel 314 driving motor 316 rotates, driving the reel 314 to rotate in the original direction of rotation, causing the head of the steel skin of the eye to separate from the reel. After the steel skin of the eye is opened, the translation motor 345 rotates, driving the frame 331 to slide horizontally to the left, so that the reel 314 is pulled out of the eye of the steel coil and returns to its original position. The lifting cylinder 332 works to adjust the height of the reel seat 311 so that the opening on the reel 314 faces the guide plate 4, waiting for the entry of the next eye of the steel skin.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
