Description

Technical Field

[0001] The present invention relates to the technical field of coil packaging, and particularly relates to a coil packaging device. Background Art

[0002] The coil is a cylinder of plastic film. After the coil is manufactured, it needs to be transported to various places for sale. In order to protect the integrity of the coil during transportation, reduce wear, and increase the transportation quantity, the coil needs to be packaged. Currently, in this industry, manual packaging is mainly used, and there are few mechanical devices for auxiliary packaging. The working labor intensity is high, and the degree of automation is low. Generally, the coil is lifted by a crane. At this time, the axis of the coil extends horizontally, and then the packaging film is wound around the outer surface of the film roll, and then the film roll is lifted and transported to the storage rack to wait for handling. Not only is the efficiency of lifting and manual film winding low, but all types of film rolls can only be stored horizontally. In order to improve the handling efficiency and the utilization rate of the storage space, it is now desired to stack some coils with a larger diameter and a shorter length. Since the weight of the film roll is large, multiple workers need to cooperate to carry it, and the labor intensity of manual handling is high.

[0003] It can be seen that the existing technology still needs to be improved. Summary of the Invention

Detailed implementation manners

[0033] The present invention provides a coil packaging device. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0034] In this article, "front" refers to the direction along which the coil moves, that is Figure 1 the direction of the arrow in, and the front is opposite to the rear.

[0035] Please refer to Figures 1 - 3, the present invention provides a coil packaging device, including a coil receiving conveyor line a1, a packaging conveyor line, a coil discharging conveyor line d, a horizontal coil discharging device e, and a vertical coil discharging device f that are sequentially connected in the front and back. The coil receiving conveyor line a1 is used to receive coils, and the conveying direction of the coil m is parallel to its axis direction. A coil diameter detection device and a coil length detection device are provided at the tail of the coil receiving conveyor line a1. A coil driving device k for driving the coil to rotate and a film wrapping device g for winding the packaging film g28 around the coil are provided on one side of the packaging conveyor line, and a paper cover fastening device h for installing paper covers on both ends of the coil is provided on the other side; the horizontal coil discharging device e is used to laterally push the film coil onto the coil discharging storage rack e4, and the vertical coil discharging device f is used to flip the coil to make the axis of the coil vertical and stack a plurality of film coils. The coil receiving conveyor line a1, the packaging conveyor line, the coil discharging conveyor line d, the horizontal coil discharging device e, and the vertical coil discharging device f are all controlled by the coil packaging control system to work.

[0036] During operation, after the coil receiving conveyor line a1 receives the coil, the coil m is placed horizontally. Driven by the coil receiving conveyor line a1, the coil is conveyed forward. After the coil m passes through the coil diameter detection device and the coil length detection device, the coil packaging control system calculates the diameter and length of the coil; then the coil is conveyed to the packaging conveyor line, and the packaging conveyor line conveys the coil to the film wrapping station. A weighing sensor is provided at the film wrapping station, and the weighing sensor detects the weight of the coil and feeds it back to the coil packaging control system. The coil driving device k pushes the coil away from the packaging conveyor line and drives the coil to rotate, so as to cooperate with the film wrapping device g to automatically wind the packaging film g28 around the coil. At the same time, the paper cover fastening device h fastens the paper covers on both ends of the coil; then the coil driving device k releases the coil, and the coil returns to the packaging conveyor line. The packaging conveyor line conveys the coil forward to the coil discharging conveyor line d; finally, the coil packaging control system automatically selects the vertical coil discharging method or the horizontal coil discharging method according to the ratio of the diameter to the length of the film coil. Film coils with a larger diameter and a shorter length will be stacked and discharged through the vertical coil discharging device f, automatically completing the stacking of the film coils, which is efficient and safe, and solves the problems caused by manual stacking. Film coils with a larger diameter and a shorter length can be understood as film coils with a film diameter: film length ≥ 3:1; while film coils with a smaller diameter and a longer length will be horizontally arranged and discharged through the horizontal coil discharging device e and cached on the coil discharging storage rack waiting for further handling by a forklift. Film coils with a smaller diameter and a longer length can be understood as film coils with a film diameter: film length < 3:1.

[0037] Specifically, a sub-roll conveying line b1 is provided between the coiling conveying line a1 and the packaging conveying line, and a sub-roll platform b2 is provided on one side of the sub-roll conveying line b1. In order to better stack the coils of the same size together and control the number of coils in each stack, it is necessary to manually intervene in the packaging sequence of the coils to achieve pre-classification of the coils, so that the coils of the same size can be continuously unrolled. When adjusting the packaging sequence of the coils, the staff pushes the coils on the sub-roll conveying line b1 onto the sub-roll platform b2, and the coils are cached on the sub-roll platform b2. When the appropriate time comes, the coils on the sub-roll platform b2 are pushed back onto the sub-roll conveying line b1, so as to achieve the purpose of adjusting the packaging sequence of the coils.

[0038] Please refer to Figure 1 and Figure 5 , the structures of the coiling conveying line a1, the sub-roll conveying line b1, the packaging conveying line and the unrolling conveying line d are the same, and each includes a conveying frame a3, a plurality of V-shaped roller groups a4 arranged along the conveying direction on the conveying frame a3, a roller group driving mechanism a5 for driving all the V-shaped roller groups a4 to move synchronously, a conveyor belt a6, and a conveyor belt tensioning assembly a7 for adjusting the tension of the conveyor belt a6. The conveyor belt a6 is wound around the roller group driving mechanism a5, the conveyor belt tensioning assembly a7 and a plurality of V-shaped roller groups a4. In actual application, the roller group driving mechanism a5 drives the conveyor belt a6 to roll through the V-shaped roller groups a4, and the conveyor belt a6 drives the coil to move when rolling. When the coil contacts the surface of the conveyor belt a6, the conveyor belt a6 will be deformed under pressure, so that the coil fits into the positioning groove formed by the V-shaped roller groups a4, and the center of gravity of the cylindrical coil is positioned on the positioning groove, preventing the coil from shaking or rolling during the movement. In addition, the V-shaped roller groups a4 also play a role in supporting the coil, enabling the conveyor belt a6 to bear coils with a larger weight and improving the load-bearing capacity of this conveyor belt. In addition, in order to prevent the coil from rolling out of the coiling conveyor line a1 due to excessive rolling force when being conveyed from equipment such as a winder / slitter to the coiling conveyor belt, a coil blocking frame a2 for blocking the coil is provided beside the coiling conveyor line a1.

[0039] Specifically, see Figure 5As shown in the figure, the coil length detection device includes a gantry p1 and an opposed sensor p2 disposed on the gantry p1; the opposed sensor p2 is electrically connected to the coil packaging control system. After the coil is received by the coil receiving conveyor a1, the coil is circumferentially positioned by the V-shaped roller set a4 so that the coil does not rotate by itself, and the axis of the coil is parallel to the conveying direction, that is, the coil is placed horizontally. Driven by the coil receiving conveyor a1, the coil can only be conveyed forward; when the coil passes through the gantry p1, the front end of the coil will first trigger the opposed sensor p2, and the opposed sensor p2 feeds back a signal to the coil packaging control system. During the process that the coil passes through the gantry p1, the opposed sensor p2 is continuously triggered and responded until the rear end of the coil completely passes through the gantry p1, and then the opposed sensor p2 stops triggering. The coil packaging control system obtains the response duration t1 of the opposed sensor p2. On the basis of the preset conveying speed v1 of the coil receiving conveyor a1, the coil length L can be calculated as L = t1v1.

[0040] Further, the coil diameter detection device includes a lifting frame p3 disposed on the top of the gantry p1 and a lifting frame p3 driving device for driving the lifting frame p3 to move up and down. A horizontally arranged pressure sensor p5 is provided on the bottom surface of the lifting frame p3, and the pressure sensor p5 is electrically connected to the coil packaging control system. During the process that the coil passes through the gantry p1, the lifting frame p3 driving device drives the lifting frame p3 and the pressure sensor p5 to descend until the pressure sensor p5 touches the coil. Then the pressure sensor p5 feeds back a signal to the coil packaging control system, and the pressure sensor p5 touches and then resets to the initial position. The coil packaging control system obtains the downward movement duration t2 of the pressure sensor p5. On the basis of the preset conveying speed v2 of the lifting frame p3 and the height difference h between the initial position of the pressure sensor p5 and the coil receiving conveyor a1, the coil diameter D can be calculated as D = h - t2v2.

[0041] Specifically, see Figure 3 and Figure 4As shown, the coil driving device k includes a driving roller bracket disposed between the packaging conveying line and the film wrapping device g, a driving roller k2 rotatably disposed on the driving roller bracket, a driving roller driving device for driving the driving roller k2 to rotate, a top roller bracket, a top roller swing frame k5 swingably disposed on the top roller bracket, a top roller driving cylinder for driving the top roller swing frame k5 to swing, and a top roller k7 rotatably disposed on the top roller swing frame k5. The top roller k7 and the driving roller k2 extend in the front-rear direction. When the coil is transported to the packaging conveying line, the top roller driving cylinder drives the top roller swing frame k5 to swing, driving the top roller k7 to swing towards the driving roller k2. Subsequently, the top roller k7 pushes the coil onto the driving roller k2. At this time, the coil disengages from the packaging conveying line, and the coil is jointly supported by the top roller k7 and the driving roller k2. Then, the driving roller driving device drives the driving roller k2 to rotate, driving the coil to rotate, and cooperating with the film wrapping device g to complete the winding of the packaging film g28 around the coil.

[0042] Specifically, as shown in Figures 6 - 9 As shown, the film wrapping device g includes a film wrapping base g1, a film wrapping head g2 slidably disposed on the film wrapping base g1, and a head driving device (not visible in the figure) for driving the film wrapping head g2 to move back and forth. The film wrapping head g2 includes a film wrapping bottom frame g20, a packaging film guiding mechanism g21 disposed on the film wrapping bottom frame g20, a pushing frame g22, and a film feeding mechanism g23. The pushing frame g22 is disposed on the packaging film guiding mechanism g21, the pushing frame g22 is slidably connected to the packaging film guiding mechanism g21, the film feeding mechanism g23 is disposed at the bottom of the pushing frame g22, and one or more tape sticking mechanisms g24 are distributed at the bottom of the film feeding mechanism g23. The tape sticking mechanism g24 is movably connected to the film feeding mechanism g23; the packaging film guiding mechanism g21 is used for guiding the packaging film g28 to the film feeding mechanism g23; the film feeding mechanism g23 is used for winding the packaging film g28 around the coil; the tape sticking mechanism g24 is used for sticking the tape to bond the packaging film g28 to the coil.

[0043] The packaging film g28 enters the packaging film guiding mechanism g21 and is pulled forward by rolling the packaging film guiding mechanism g21. The free end of the packaging film g28 passes through the packaging film guiding mechanism g21 and is connected to the film-applying mechanism g23. The pushing frame g22 pushes the film-applying mechanism g23 to one side of the coil. The tape pasting mechanism g24 pushes toward the coil and sticks one end of the tape to the surface of the coil. Then the tape pasting mechanism g24 rotates toward the film-applying mechanism g23 to make the other end of the tape adhere to the packaging film g28, so that one end of the packaging film g28 is relatively fixed to the surface of the coil. Finally, the coil driving device k is used to rotate the coil so that the packaging film g28 is wrapped around the surface of the coil m. When the packaging film g28 starts to wrap around the coil, the tape sticking mechanism g24 cuts off the tape, so that the packaging film g28 follows the rotation of the coil to automatically wrap, and according to the length of the coil, the head driving device drives the film wrapping head g2 to move back and forth a suitable distance, so that the surrounding walls of the coil are all wrapped with the packaging film g28. After the coil packaging is completed, the packaging film g28 is cut off, and the pushing rack g22 retracts to reset the film-applying mechanism g23, thereby completing the automatic packaging process of the coil; the packaging film actuating mechanism g21, the pushing rack g22, the film-applying mechanism g23 and the tape sticking mechanism g24 are used in combination to realize automatic packaging of the coil, avoid uneven packaging quality, and save a lot of labor costs.

[0044] In one embodiment, the packaging film driving mechanism g21 includes a guide roller group g211, and the guide roller group g211 includes multiple guide rollers, and any guide roller is transmission-connected to the packaging film g28 driving device. The packaging film g28 is wound around the guide roller group g211, and the packaging film g28 is guided out of the packaging film driving mechanism g21 step by step through the guide roller group g211, and the guide roller is actively driven to rotate through the packaging film g28 driving device, so that the packaging film g28 is transmitted.

[0045] Furthermore, an adsorption mechanism g25 is provided on one side of the film-applying mechanism g23, and the adsorption mechanism g25 is located above the tape-pasting mechanism g24; the adsorption mechanism g25 is used to adsorb the packaging film g28; when the packaging film g28 is not wound, the adsorption mechanism g25 adsorbs the free end of the packaging film g28 to prevent the packaging film g28 from being rolled back into the film-applying mechanism g23, and the adsorption mechanism g25 fixes the free end of the packaging film g28, which makes it easier for the tape-pasting mechanism g24 to paste the tape on the packaging film g28.

[0046] A plurality of rotatable guide rollers g231 are arranged inside the upper film mechanism g23, and the plurality of guide rollers g231 are all located above the adsorption mechanism g25; the guide rollers g231 are used for the packaging film g28 to wind around and guide the packaging film g28 to the lower part of the adsorption mechanism g25; after the packaging film g28 enters the upper film mechanism g23, it winds around the plurality of guide rollers g231 in sequence, and the guide rollers g231 guide the packaging film g28 to the lower part of the adsorption mechanism g25. During the process of the packaging film g28 winding the coil material, the guide rollers g231 roll along with the movement of the packaging film g28, so as to play a guiding role for the packaging film g28, making the packaging film g28 more smooth during the winding process and preventing the problem of winding disorder.

[0047] Furthermore, a fusing mechanism g232 that can swing towards the adsorption mechanism g25 is arranged on one side of the upper film mechanism g23; the fusing mechanism g232 is used for cutting off the packaging film g28; during use, after the coil material finishes winding the packaging film g28, the fusing mechanism g232 swings towards the lower part of the packaging film g28 and cuts off the packaging film g28 by means of heating and fusing, thereby completing the packaging process of the coil material. After the packaging film g28 is cut off, the fusing mechanism g232 swings back, and the adsorption mechanism g25 adsorbs the free end of the packaging film g28 again to prevent the packaging film g28 from rebounding into the upper film mechanism g23.

[0048] Specifically, as shown in Figure 2 and Figure 4 The paper cover fastening device h includes a loading frame h1, two paper cover gripping hands h2 respectively arranged on both sides of the loading frame h1, a paper cover storage h3 arranged below the paper cover gripping hands h2. A material taking frame h4 is arranged between the loading frame h1 and the packaging conveying line, two flipping gripping hands h5 slidably arranged on the material taking frame h4, and a flipping gripping hand driving device h6 for driving the two flipping gripping hands h5 to approach or move away from each other. The flipping gripping hands h5 are used to take away the paper covers on the paper cover gripping hands h2 and fasten the paper covers to the ends of the coil materials. During paper cover packaging, the paper cover gripping hands h2 are driven by the loading lifting device h7 to descend and horizontally suck the paper covers on the paper cover storage h3, then turn the paper covers over to make the paper covers stand vertically. The paper cover gripping hands h2 are driven by the feeding driving device h8 to move towards the packaging conveying line direction. Subsequently, the two flipping gripping hands h5 flip towards the paper cover gripping hands h2 direction, suck the corresponding paper covers on the paper cover gripping hands h2, then the two flipping gripping hands h5 flip towards the coil material direction to make the paper covers face the ends of the coil materials, and then the flipping gripping hand driving device h6 drives the two flipping gripping hands h5 to move towards the ends of the coil materials, so that the flipping gripping hands h5 fasten the paper covers on the coil materials, automatically completing the fastening work of the paper covers.

[0049] Furthermore, as shown in Figure 4As shown, the coil driving device k further includes a pressure roller swing frame k82 rotatably arranged on the loading rack h1, a pressure roller k81 rotatably arranged on the pressure roller swing frame k82, and a pressure roller k81 driving cylinder. When the coil is being wrapped, the pressure roller k81 driving cylinder drives the pressure roller swing frame k82 to swing, so that the pressure roller k81 presses on the top of the coil. On the one hand, it prevents the pulling force of the winding film from lifting the coil, and on the other hand, it reduces the jumping of the coil, enabling the packaging film g28 to be wound more tightly on the coil.

[0050] Specifically, the horizontal coil discharging device e includes a horizontal bottom frame e1 and a swing conveyor line e2 swingably arranged on the horizontal bottom frame e1. The swing conveyor line e2 is connected to the horizontal bottom frame e1 through a hinge. An outgoing coil storage rack e4 is arranged on one side of the horizontal bottom frame e1, and a side push driving cylinder e3 for driving the swing conveyor line e2 to swing towards the outgoing coil storage rack e4 is arranged on the horizontal bottom frame e1.

[0051] After the film roll is packaged, its axis will be parallel to the conveying direction. At this time, the coil packaging control system automatically selects the vertical or horizontal coil discharging method according to the ratio of the diameter to the length of the film roll, with strong applicability and high automation, effectively improving the handling efficiency and shipping rate. If the horizontal coil discharging method is adopted, when the film roll completely enters the swing conveyor line e2, the forward conveying of the film roll stops. At this time, the side push driving mechanism drives the swing conveyor line e2 to swing towards the outgoing coil storage rack e4, causing the swing conveyor line e2 to tilt, so that the film roll rolls onto the outgoing coil storage rack e4 automatically for buffering, waiting for further handling by a forklift. When the vertical coil discharging method is adopted, the film roll passes through the swing conveyor line e2 and enters the vertical coil discharging device f, and the vertical coil discharging device f starts to stack the film rolls.

[0052] Specifically, the vertical coil discharging device f includes a flipping conveyor line f1, a horizontal conveyor line f2 connected to the flipping conveyor line f1, centering mechanisms f3 arranged on both sides of the horizontal conveyor line f2, and a stacking mechanism f4 arranged above the horizontal conveyor line f2; the flipping conveyor line f1 is used to flip and convey the film roll forward, so that one end face of the film roll presses against the flipping conveyor line f1; a stacking station f5 is provided on the horizontal conveyor line f2; the centering mechanisms f3 are used to push the film roll to the stacking station f5; the stacking mechanism f4 is used to grab the film roll at the stacking station f5 and drive the film roll to move up and down to achieve stacking.

[0053] The working method of the vertical unwinding is briefly described as follows: when the first film roll is conveyed to the vertical film roll unwinding device f, the flip conveyor line f1 first receives the first film roll. At this time, the peripheral wall of the first film roll is pressed against the flip conveyor line f1, and the axis of the first film roll is parallel to the conveying direction. Then the flip conveyor line f1 flips the film roll 90°, so that the end face of the first film roll is pressed against the flip conveyor line f1, and the axis of the first film roll is parallel to the vertical direction. Then the flip conveyor line f1 conveys the first film roll to the horizontal conveyor line f2, and the horizontal conveyor line f2 conveys the first film roll forward to the stacking station f5. Since the first film roll will be displaced after being flipped, it is impossible to determine whether the first film roll is accurately moved to the stacking station f5 at this time, so the position of the first film roll is corrected by the centering mechanism f3, and the first film roll is accurately stacked. The first film roll is accurately pushed to the palletizing station f5, and the next film roll (hereinafter referred to as the second film roll) is also turned 90 degrees through the turning conveyor line f1 and conveyed to the horizontal conveyor line f2. Before the second film roll enters the horizontal conveyor line f2, the stacking mechanism f4 grabs the first film roll and lifts the first film roll to a suitable height, and then the horizontal conveyor line f2 conveys the second film roll forward to the palletizing station f5. Similarly, the position of the second film roll is corrected by the centering mechanism f3, and the second film roll is accurately pushed to the palletizing station f5. At this time, the second film roll is located directly below the first film roll. Then the stacking mechanism f4 stacks the first film roll on the second film roll, and finally releases the first film roll. The first film roll and the second film roll are conveyed forward through the horizontal conveyor line f2, waiting for further handling and shipment. Of course, the number of film rolls stacked can be 3 or more. On the basis of completing the palletizing of two film rolls, the palletizing is continued according to the above-mentioned palletizing method, which will not be repeated here.

[0054] Specifically, the centering mechanism f3 includes two symmetrically arranged clamping jaws, each of which includes a bracket f31, two arc-shaped jaws f32 symmetrically arranged on the top of the bracket f31, and a clamping jaw driving assembly f33 arranged on the bracket f31 and used to drive the two arc-shaped jaws f32 to close or open each other; one end of the two arc-shaped jaws f32 is rotatably arranged on the bracket f31. In the initial state, the two arc-shaped jaws f32 in each clamping jaw assembly open toward the horizontal conveyor line f2 to form a "w" structure. When the horizontal conveyor line f2 transports the film roll to the stacking station f5, the two clamping jaw driving assemblies f33 synchronously drive the four arc-shaped jaws f32 to close toward the stacking station f5, and the free ends of the four arc-shaped jaws f32 form a push correction for the film roll. When the free ends of the four arc-shaped jaws f32 clamp the film roll, it means that the film roll is accurately positioned to the stacking station f5.

[0055] Specifically, the stacking mechanism f4 includes two vertical frames f41, a cross beam f42 connecting the tops of the two vertical frames f41, two first tracks f43 vertically arranged between the two vertical frames f41, and a roll clamping driving cylinder f44 for driving the two first tracks f43 to approach or move away from each other; there are two roll clamping driving cylinders f44, the cylinder body of the roll clamping driving cylinder f44 is fixed on the vertical frame f41, and the end of the piston rod of the roll clamping driving cylinder f44 is connected to the first track f43. A roll clamping plate f45 is slidably connected to each first track f43. The roll clamping end face of the roll clamping plate f45 is an arc surface and extends vertically, so that the roll clamping end face can better fit the peripheral wall of the film roll, increasing the contact area between the roll clamping plate f45 and the film roll, improving the lifting friction of the film roll, and having the ability to grab several film rolls at one time. An elevating driving mechanism f46 for driving the roll clamping plate f45 to move up and down is arranged on the first track f43. The elevating driving mechanism f46 can adopt an electric push rod, a linear module, a lead screw mechanism, etc., and its main effect is to provide an output end for linear motion. During stacking, the roll clamping driving mechanism drives the two first tracks f43 and the roll clamping plates f45 to move synchronously towards the stacking station until the two roll clamping plates f45 clamp the film roll. Then, the elevating driving mechanism f46 drives the roll clamping plate f45 to move up, lifting the film roll to a certain height so that there is space for the next film roll to enter the stacking station. When the next film roll is accurately placed at the stacking station, the elevating driving mechanism f46 drives the roll clamping plate f45 to move down, stacking the previous film roll on the next film roll. It can be seen that the centering mechanism f3 and the stacking mechanism f4 cooperate with each other to automatically complete the stacking of film rolls, which is efficient and safe, and solves the problems caused by manual stacking.

[0056] Further, a base f47 is provided at the bottom end of the first track f43, and a second track f48 extending left and right is provided on the ground. The base f47 is slidably connected to the second track f48. A third track (invisible in the figure) is provided on the bottom surface of the cross beam f42, and the top end of each first track f43 is slidably connected to the third track. By such a setting, the first track f43 always maintains a vertical extension under the positioning of the second track f48 and the third track, and will not tilt during the movement process. Moreover, the moving resistance of the first track f43 is small, and it can move left and right smoothly.

[0057] Specifically, the flipping conveyor line f1 includes a chassis f11, a flipping frame f12 rotatably arranged on the chassis f11, a horizontal conveyor frame f13 arranged downstream of the flipping frame f12, a plurality of first guide roller assemblies f14 arranged on the flipping frame f12, a first guide roller driving mechanism f15 for driving all the guide roller assemblies to move synchronously, and a flipping pneumatic push rod f16 for driving the flipping frame f12 to flip towards the horizontal conveyor frame f13; a plurality of second guide roller assemblies f18 and a second guide roller driving mechanism f17 for driving all the second guide roller assemblies f18 to move synchronously are arranged on the horizontal conveyor frame f13. Driven by the first guide roller assembly f14, the film roll completely enters the flipping frame f12 in a horizontal state. Subsequently, the flipping driving mechanism drives the flipping frame f12 to flip 90° towards the horizontal conveyor frame f13, so that the film roll flips and falls onto the second guide roller assembly f18, that is, switches from the horizontal state to the vertical state. Then, the second guide roller assembly f18 drives the film roll into the horizontal conveyor line f2. The first guide roller driving mechanism f15 and the second guide roller driving mechanism f17 can adopt a transmission method formed by a sprocket and a chain or a transmission method formed by a pulley and a belt.

[0058] Further, the first guide roller assembly f14 includes two first conveying rollers symmetrically arranged left and right. The two first conveying rollers are inclined to form a V-shaped positioning groove; a driven gear is provided at one end of each first conveying roller. The center of gravity of the coil material is positioned on the V-shaped positioning groove, playing a role of centering and positioning, and preventing the coil material from shaking or rolling during the movement. The second guide roller assembly f18 is a second conveying roller extending in the left-right direction, and the second guide roller driving mechanism f17 drives all the second conveying rollers to move synchronously through a chain transmission method.

[0059] In this embodiment, a first automatic labeling device t1 for pasting labels on the core is arranged at the tail of the coil receiving conveyor line a1, and a second automatic labeling device t2 for pasting labels on the outer surface of the coil material is arranged beside the coil discharging conveyor line d.
