Description

Technical Field

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

[0002] Coils are cylindrical rolls of plastic film or cloth rolls (such as non-woven fabric rolls). After the coils are manufactured, they need to be transported to various places for sale. In order to protect the integrity of the coils during transportation and handling and reduce wear, it is necessary to package and protect the coils.

[0003] However, at present, manual packaging is usually adopted. First, the coil is transported to the coil revolving rack, then a section of double-sided tape is manually cut, and then this section of double-sided tape is pasted on the outer peripheral surface of the coil. The isolation tape is torn off to leave a section of double-sided tape, and then the free end of the packaging film is fixed on the coil through the double-sided tape. Then, by driving the coil to rotate, the packaging film winds around the coil several times and then holds the coil tightly. Then, the packaging film reciprocates along the axial direction of the coil to achieve winding packaging. Finally, the packaging film is cut off to complete the packaging of the coil. Due to the large production volume, a large number of workers are required to maintain the packaging efficiency, resulting in high labor costs.

[0004] In order to improve the automation level of the enterprise, improve the packaging efficiency, and save labor, it is urgent to develop an automatic coil packaging device. Summary of the Invention

DETAILED DESCRIPTION

[0030] The present invention provides an automatic coil packaging device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0031] In this article, "rear" refers to the conveying direction of the coil, that is, the direction from the feeding table 11 to the unloading table 12, and the opposite of "front" and "rear". The descriptions of "first", "second", etc. in this article are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features; in order to facilitate the observation of the parts in the chassis, the attached Figure 2 ,4 In the chassis of 5 and 8, the side plates are hidden; attached Figure 2 and 3 The arrow direction in is the rotation direction of the coil material.

[0032] Please refer to Figures 1-10 , the present invention provides a coil material automatic packaging device, including a feeding table 11, a blanking table 12 arranged downstream of the feeding table 11, a coil material driving device 2 arranged between the feeding table 11 and the blanking table 12, a first distance measuring component 31 and a second distance measuring component 32 respectively arranged at the left and right ends of the coil material driving device 2, two upper paper cover devices 4 respectively arranged on the left and right sides of the coil material driving device 2, a beam frame 71 fixedly arranged on the blanking table 12, a packaging film winding machine head 8 arranged on the beam frame 71, a power module for driving the movement of the packaging film winding machine head 8, and a pushing device 5 for pushing the packaged coil material onto the blanking table 12; the coil material driving device 2 is used to drive the coil material to rotate horizontally; the first distance measuring component 31 is used to measure the distance between it and the left end of the coil material 92, and the second distance measuring component 32 is used to measure the distance between it and the right end of the coil material 92; the two upper paper cover devices 4 respectively cover the upper paper covers 93 on both ends of the coil material; the packaging film winding machine head 8 is used to wind the packaging film 8331 on the coil material 92; the coil material driving device 2, the first distance measuring component 31, the second distance measuring component 32, the upper paper cover device 4, the packaging film winding machine head 8, the power module, and the pushing device 5 are all controlled by the electric control box 6 to work.

[0033] The staff pushes the coil material onto the packaging station 91 of the coil material driving device 2, and the coil material 92 is in a static state under the support of the coil material driving device 2; subsequently, the first distance measuring component 31 measures the distance between it and the left end of the coil material 92, and the second distance measuring component 32 measures the distance between it and the right end of the coil material 92. After the controller obtains the information of the first distance measuring component 31 and the second distance measuring component 32, it calculates the lateral position of the coil material relative to the coil material driving device 2 (that is, the position points of the left end and the right end of the coil material), and the width of the coil material. The two upper paper cover devices 4 respectively cover the upper paper covers 93 on both ends of the coil material; furthermore, the electric control box 6 controls the packaging film winding machine head 8 to move to the film loading position according to the lateral position information of the coil material, and the coil material driving device 2 cooperates with the packaging film winding machine head 8 to load the film, and then determines the reciprocating lateral movement and winding packaging stroke according to the coil material width information. Finally, the pushing device 5 pushes the packaged coil material onto the blanking table 12, and the coil material rolls to the discharge end of the blanking table 12, and the staff takes away the coil material. It can be seen that the coil material automatic packaging device provided by the present invention is convenient to use. The staff only needs to push the coil material 92 to the packaging station 91, and it can automatically detect the coil material, and each device cooperates with each other to automatically complete the coil material winding and packaging work, with a high degree of intelligence. Compared with the existing manual packaging, the packaging quality of each coil material is consistent, the packaging film is wound smoothly and firmly, the packaging efficiency is higher, and the use of labor force is greatly reduced.

[0034] The electric control box 6 includes a box body, a PLC controller arranged inside the box body, and related control circuits.

[0035] Specifically, as shown in Figure 9 and Figure 10 As shown, the first distance measuring component 31 and the second distance measuring component 32 include a first vertical frame (invisible in the figure) and a first laser distance sensor 311 arranged at the top of the first vertical frame. The second distance measuring component 32 includes a second vertical frame 321 and a second laser distance sensor 322 arranged at the top of the second vertical frame 321. Since the distance between the first optical distance sensor and the second optical distance sensor is fixed, the controller obtains that the distance measured by the first laser distance sensor 311 from it to the left end of the coil is L1; the controller obtains that the distance measured by the second laser distance sensor 322 from it to the right end of the coil is L2; the controller calculates the width W of the coil, W = D - L1 - L2. When determining the position of the upper film plane, a plane rectangular coordinate system is set under the horizontal projection, the X-axis is the connection line between the first laser distance sensor 311 and the second laser distance sensor 322; the position where the first laser distance sensor 311 is located is the coordinate origin (0, 0); the Y-axis passes through the coordinate origin and is perpendicular to the X-axis; the controller calculates that the coordinate of the left end of the coil is N1(L1, 0), and the controller calculates that the coordinate of the right end of the coil is N2(D - L2, 0). In practical applications, the controller can calculate the horizontal position of the upper film of the packaging film winding head 8 according to the coordinates N1(L1, 0) and N2(D - L2, 0) (such as the coordinate is N3(L1 + △K1, 0), △K1 is a preset offset; or the coordinate is N4(D - L2 - △K2, 0), △K2 is a preset offset).

[0036] In this embodiment, in order to have more space to pre-place the coil and extend the feeding stroke, a material placing table 13 is provided upstream of the feeding table 11 (as shown in Figure 1 ) and the material placing table 13 is closely connected to the feeding table 11.

[0037] Specifically, as shown in Figure 4 and Figure 5 As shown, the packaging film winding head 8 includes a machine case 81, a double-sided tape pasting device 82, a film feeding device 83 and a cutting device 84 arranged inside the machine case 81; the double-sided tape pasting device 82 is located upstream of the film feeding device 83; the double-sided tape pasting device 82 is used to paste a double-sided tape 8271 on the outer peripheral surface of the coil, so that the packaging film unwound by the film feeding device 83 is fixed on the coil 92 through the double-sided tape 8271; the cutting device 84 is used to cut the packaging film 8331.

[0038] During operation, the power module drives the packaging film winding head 8 above the coil 92. Then, the coil driving device 2 drives the coil 92 to rotate, so that the double-sided tape sticking device 82 sticks a section of double-sided tape 8271 on the coil. And the film feeding device 83 unwinds the packaging film 8331. As the coil 92 rotates, the double-sided tape 8271 adheres to the packaging film 8331 and winds several circles to ensure that the packaging film holds the coil tightly. Subsequently, the power module drives the packaging film winding head 8 to move horizontally back and forth, so that the packaging film 8331 moves left and right on the coil for winding. After the winding packaging is completed, a section of taut packaging film is formed between the film feeding device 83 and the coil 92. Then, the cutting device 84 automatically cuts the packaging film.

[0039] Further, please refer to Figure 6 and Figure 7 The double-sided tape sticking device 82 includes a bracket 821 arranged in the chassis 81, a tape unwinding mechanism 822 arranged on the bracket 821, a winding mechanism 823, a braking mechanism 824, a rotatable pressing wheel 825 arranged below the tape unwinding mechanism 822 and the winding mechanism 823, and a lifting driving device 826 for driving the pressing wheel 825 to lift and lower; the tape unwinding mechanism 822 is used for unwinding the double-sided tape 827, the winding mechanism 823 is used for recycling the release tape 8272, the pressing wheel 825 is used for pressing the double-sided tape 8271 on the double-sided tape 827 onto the coil 92, and the braking mechanism 824 is used for restricting the rotation of the double-sided tape 827 to stop the unwinding of the double-sided tape 827. It should be understood that the double-sided tape 827 passes around the pressing wheel 825 and the winding mechanism 823 in sequence. When the pressing wheel 825 presses against the outer peripheral surface of the coil, a fixed glue line 828 is formed. It can also be understood that this fixed glue line 828 is a dividing line. There is double-sided tape 8271 on the release tape between the fixed glue line 828 and the double-sided tape 827, and there is no double-sided tape 8271 on the material separating tape between the fixed glue line 828 and the winding mechanism 823.

[0040] When applying the adhesive tape, the lifting drive device 826 drives the pressure wheel 825 to descend, so that the pressure wheel 825 presses against the outer peripheral surface of the coil material 92. At the same time, the double-sided adhesive tape 827 is pulled by the pressure wheel 825 to realize unwinding; at this time, the double-sided adhesive 8271 located at the fixed adhesive line 828 is pasted on the coil material 92, and then the coil drive device 2 and the winding mechanism 823 act simultaneously to pull the double-sided adhesive tape 827 to enable the tape unwinding mechanism 822 to unwind. Here, the rotation directions of the pressure wheel 825 and the coil material 92 are opposite. The double-sided adhesive 8271 on the coil material 92 unfolds and adheres along the outer peripheral surface of the coil material as the coil material rotates. When the pasting length of the double-sided adhesive reaches the preset length (5 - 10 cm), the braking mechanism 824 brakes and holds the double-sided adhesive tape 827, restricting the rotation of the double-sided adhesive tape 827 to stop unwinding. At the same time, the winding mechanism 823 stops winding the isolation tape 8272. The double-sided adhesive 8271 is pulled by the coil material 92 and breaks at the fixed adhesive line 828. Finally, the lifting drive device 826 drives the pressure wheel 825 to rise away from the coil material 92, so that the double-sided adhesive tape applying device 82 completes the adhesive tape application action. The automation degree is high, the packaging efficiency is improved, and the use of labor in this adhesive tape application process is reduced. Since the free end of the double-sided adhesive 8271 is successively located at the fixed adhesive line 828 after each adhesive tape application action, the working continuity and reliability of the double-sided adhesive tape applying device 82 are ensured.

[0041] Further, please refer to Figure 6 As shown in the figure, the braking mechanism 824 includes a stop block 8241, a support arm 8242 fixedly arranged on the bracket 821, and a braking cylinder 8243 arranged at the top of the support arm 8242; the output end of the braking cylinder 8243 is connected to the stop block 8241 through a slider 8245. A guide rail 8244 extending along the length direction of the support arm 8242 is arranged on the support arm 8242, and the slider 8245 is slidably connected to the guide rail 8244. The guide rail 8244 can not only guide the movement of the slider 8245 to ensure that the axis of the braking cylinder 8243 intersects with the axis of the double-sided adhesive tape 827, but also limit the slider 8245 to prevent the piston rod of the braking cylinder 8243 from being deformed by the tangential force. That is, the braking cylinder 8243 drives the stop block 8241 to press against the double-sided adhesive tape 827, so that the double-sided adhesive tape 827 is immediately braked and stopped, maintaining a static state. It should be understood that the frictional force between the stop block 8241 and the double-sided adhesive tape 827 is greater than the breaking force of the double-sided adhesive to ensure that the double-sided adhesive can be smoothly broken.

[0042] Preferably, please refer to Figure 7, the lifting drive device 826 includes a slide cylinder 8261 provided on the bracket 821. A receiving seat 8262 is provided at the output end of the slide cylinder, and the pressing wheel 825 is rotatably provided on the receiving seat 8262. The slide cylinder 8261 has the advantages of high guiding accuracy, anti-torque resistance, strong load capacity, and stable operation, ensuring that the pressing wheel 825 will not move automatically under external force during the process of pressing the coil material, and ensuring that the double-sided tape is broken at the fixed glue line 828.

[0043] Preferably, please refer to Figure 6 and Figure 7 , the tape unwinding mechanism 822 includes a rotating shaft (not visible in the figure) rotatably provided on the bracket 821, a rotation damper 8221 fixedly provided on the bracket 821, and an unwinding wheel 8222 sleeved on the rotating shaft. One end of the rotating shaft is connected to the rotation damper 8221; the double-sided tape 827 is wound around the unwinding wheel 8222. By such a setting, there is tension in the spacer tape between the tape unwinding mechanism 822, the pressing wheel 825, and the winding mechanism 823. Since the traction force of the coil material on the double-sided tape is greater than the resistance of the rotation damper 8221, the rotating shaft and the unwinding wheel 8222 can rotate to achieve unwinding.

[0044] Preferably, please refer to Figure 6 and Figure 7 , the winding mechanism 823 includes a winding roller 8231 rotatably provided on the bracket 821 and a winding drive device 8232 fixed on the bracket 821. During operation, the winding drive device 8232 drives the winding roller 8231 to rotate, so that the isolation tape 8272 is wound on the winding roller 8231. The winding drive device 8232 is preferably a pneumatic motor, and the pneumatic motor has a high starting torque, can start with load, and is easy to control.

[0045] Furthermore, please refer to Figure 4 and Figure 5 , the upper film device 83 includes a roll change mechanism 831 and a tension controller 832 provided on the chassis 81, a packaging film roll 833 provided between the roll change mechanism 831 and the tension controller 832, a first pressing roller 834 provided below the packaging film roll 833, an upper film drive device 837 for driving the first pressing roller 834 to rotate, a second pressing roller 835 provided below the tape unwinding mechanism 822, and a blowing rod 836 provided on one side of the first pressing roller 834; the blowing rod 836 is used to blow up the free end of the packaging film 8331 to increase the wrap angle formed by the packaging film and the first pressing roller 834. Here, the first pressing roller 834 and the second pressing roller 835 are parallel to each other and have the same height; the tension controller 832 is preferably a magnetic powder tension controller 832, and the magnetic powder tension controller 832 has a tension sensing function and a magnetic powder braking tension control function.

[0046] Before packaging, the blowing rod 836 continuously blows out air flow towards the bottom of the first pressing roller 834. On the one hand, the air flow blows the packaging film 8331 against the first pressing roller 834. On the other hand, the air flow blows up the free end of the packaging film 8331, making the free end of the packaging film 8331 tilt away from the blowing rod 836, thereby increasing the wrapping angle formed by the packaging film 8331 and the first pressing roller 834. Furthermore, it ensures that when the upper film is installed, the packaging film 8331 is located between the first pressing roller 834 and the coil 92, ensuring the successful installation of the film on the coil. During operation, the first pressing roller 834 presses the packaging film against the coil 92. The coil rotates under the drive of the coil driving device 2. At the same time, the upper film driving device 837 drives the first pressing roller 834 to act, pulling the packaging film roll 833 to unwind the packaging film 8331. The double-sided tape 8271 on the coil is transported to the first pressing roller 834 as the coil rotates. Thus, the double-sided tape 8271 on the coil adheres to the packaging film 8331, and it is wound several times to ensure that the packaging film tightly holds the coil.

[0047] Preferably, please refer to Figure 8 As shown in the figure, the cutting device 84 includes an electric heating cutting strip 841 that can swing around the axis of the first pressing roller 834 and is used for cutting the packaging film, and a film cutting driving mechanism 842 for driving the electric heating cutting strip 841 to swing. The electric heating cutting strip 841 includes a swing frame 8411 that can swing around the second pressing roller 835, and an electric heating strip 8412 arranged on the swing frame 8411. The film cutting driving mechanism 842 includes a film cutting cylinder 8421 and a connecting rod 8422. The cylinder end of the film cutting cylinder 8421 is hinged to the chassis 81, and the piston rod end of the film cutting cylinder 8421 is hinged to one end of the connecting rod 8422. The other end of the connecting rod 8422 is fixedly connected to the electric heating cutting strip 841. That is, the film cutting cylinder 8421 drives the electric heating cutting strip 841 to reciprocally swing within a reasonable range through the connecting rod 8422, thereby cutting the packaging film 8331 between the first pressing roller 834 and the coil 92, and the electric heating cutting strip 841 will not interfere with the packaging film 8331 between the packaging film roll 833 and the first pressing roller 834.

[0048] When cutting the film, the film cutting driving mechanism 842 drives the electric heating cutting strip 841 to swing around the axis of the first pressing roller 834 to cut the packaging film 8331. The heated electric heating cutting strip 841 can quickly fuse the packaging film 8331, the film cutting is rapid, and the cut is smooth. Finally, the film cutting driving mechanism 842 drives the electric heating cutting strip 841 to reset. At this time, the free end of the packaging film is blown up again under the action of the air flow of the blowing rod 836.

[0049] Furthermore, please refer to Figure 5The roll-changing mechanism 831 includes a roll-changing cylinder 8311 and a bearing seat 8312 arranged on the chassis 81, and a top shaft 8313 arranged in the bearing seat 8312; the top shaft 8313 can move laterally relative to the bearing seat 8312, one end of the top shaft 8313 is used to connect with the packaging film roll 833, and the other end of the top shaft 8313 is connected with a rotary joint 8314, and the piston rod end of the roll-changing cylinder 8311 is connected to the rotary joint 8314 through a connecting plate 8315. The roll-changing mechanism 831 includes a roll-changing cylinder 8311 and a bearing seat 8312 arranged on the chassis 81, and a top shaft 8313 arranged in the bearing seat 8312; the top shaft 8313 can move horizontally relative to the bearing seat 8312, one end of the top shaft 8313 is used to connect with the packaging film roll 833, and the other end of the top shaft 8313 is connected with a rotary joint 8314, and the piston rod end of the roll-changing cylinder 8311 is connected to the rotary joint 8314 through a connecting plate 8315. That is, the roll-changing cylinder 8311 drives the top shaft 8313 to separate from the packaging film roll 833 through the transmission of the connecting plate 8315 and the rotary joint 8314, and due to the action of the rotary joint 8314, the top shaft 8313 rotates with respect to the packaging film roll 833, while the connecting plate 8315 does not rotate with the top shaft 8313.

[0050] Preferably, see Figure 4 The housing 81 is provided with a sliding sleeve 8316, a guide shaft 8317 is inserted into the sliding sleeve 8316, and one end of the guide shaft 8317 is fixedly connected to the connecting plate 8315. The guide shaft 8317 is slidably connected to the sliding sleeve 8316, and the guide shaft 8317 can guide the movement of the connecting plate 8315 and also limit the connecting plate 8315 to prevent the piston rod of the roll-changing cylinder 8311 from being deformed by the tangential force.

[0051] Preferably, see Figure 5 The upper film driving device 837 includes a mounting frame 8371 fixed on the chassis 81, and an upper film driving motor 8372 arranged on the mounting frame 8371; a first synchronous pulley 8373 is sleeved on the output end of the upper film driving motor 8372, and a second synchronous pulley 8374 is sleeved on the end shaft of the first pressing roller 834, and the first synchronous pulley 8373 and the second synchronous pulley 8374 are connected by a first synchronous belt 8375. That is, the upper film driving motor 8372 drives the first pressing roller 834 to rotate through the transmission of the first synchronous pulley 8373, the first synchronous belt 8375, and the second synchronous pulley 8374. Due to the high stability of the synchronous belt transmission, the first pressing roller 834 can rotate smoothly. The rotation speed of the first pressing roller 834 should be equal to or less than the rotation speed of the coil.

[0052] Preferably, see Figure 1 , 9, 10, the coil driving device 2 includes a frame 21, a driving roller 22 and a driven roller 23 rotatably arranged on the frame 21, and a coil driving motor 24 installed on the frame 21; the driving roller 22 and the driven roller 23 are parallel to each other, and the coil driving motor 24 drives the driving roller 22 to rotate through a transmission component. A certain distance is provided between the driving roller 22 and the driven roller 23 to form a packaging station 91. The coil 92 rolls into the packaging station 91 along the guiding of the feeding table 11. The driving roller 22 and the driven roller 23 perform radial positioning on the coil, so that the coil cannot move by itself.

[0053] Preferably, the transmission component includes a third synchronous pulley (not shown in the figure) arranged on the end shaft of the driving roller 22, a fourth synchronous pulley (not shown in the figure) sleeved on the main shaft of the coil driving motor 24, and a second synchronous belt (not shown in the figure) connecting the third synchronous pulley and the fourth synchronous pulley. That is, when the coil driving motor 24 rotates, it drives the driving roller 22 to rotate through the transmission of the third synchronous pulley, the fourth synchronous pulley and the second synchronous belt. Due to the high stability of the transmission mode of the second synchronous belt and no slipping, the driving roller 22 can rotate smoothly. In order to prevent personnel from accidentally touching the third synchronous pulley and the fourth synchronous pulley and improve the use safety, a protective cover 25 is provided outside the third synchronous pulley and the fourth synchronous pulley.

[0054] Preferably, please refer to Figure 10 The pusher device 5 includes a plurality of pusher cylinders 51 fixedly arranged on the frame 21. The driven roller 23 is located upstream of the driving roller 22 and is rotatably installed on the receiving frame 52. The pusher cylinder 51 is vertically upward, and the end of its piston rod is connected to the bottom of the receiving frame 52. In the normal state, the piston rod of the pusher cylinder 51 retracts, and the driven roller 23 and the driving roller 22 are at the same height, so that the driving roller 22 and the driven roller 23 are in balanced force, improving the stability of the coil rotation. When pushing the material, the piston rod of the pusher cylinder 51 extends upward, making the driven roller 23 higher than the driving roller 22. The coil rolls over the driving roller 22 under the action of the thrust and then rolls into the blanking table 12. This pusher action is rapid and the control is simple.

[0055] Preferably, please refer to Figure 1 , the beam frame 71 includes two vertical beams 711 arranged oppositely on the blanking table 12 and a cross beam 712 arranged between the two vertical beams 711; the power module includes a first power module 72 for driving the vertical movement of the cross beam 712 and a second power module 73 for driving the lateral movement of the packaging film winding head 8.

[0056] When starting to apply the film, the first power module 72 drives the packaging film winding head 8 to descend, so that the first pressing roller 834 and the second pressing roller 835 jointly press on the outer peripheral surface of the coil material 92. The coil material exerts a reaction force on the first pressing roller 834 and the second pressing roller 835, and is transmitted to the first power module 72 through the packaging film winding head 8 and the cross beam 712, causing a change in the output torque of the first power module 72, thereby determining that the vertical movement of the packaging film winding head 8 is in place. The first pressing roller 834 and the second pressing roller 835 work together to ensure accurate pressure feedback of the packaging film winding head 8 and prevent slipping caused by a single pressing roller pressing the coil material.

[0057] To make the movement of the cross beam 712 more stable, a first power module 72 is provided on each vertical beam 711. The first power module 72 includes a torque motor provided at the top of the vertical beam 711, a lead screw vertically provided on the vertical beam 711, and a lead screw nut provided on the lead screw. The lead screw nut is fixedly connected to the cross beam 712; the torque motor is in transmission connection with the lead screw. The torque motor drives the lead screw to rotate, thereby driving the lead screw nut, the cross beam 712, and the components provided on the cross beam 712 to move vertically. The torque motor can still operate continuously when the rotor rotates at a low speed or even stalls (i.e., the rotor cannot rotate), without causing damage to the motor. When the first pressing roller 834 and the second pressing roller 835 press on the coil material, the torque motor is subjected to resistance, causing a change in its torque. Since the electronic control box 6 dynamically detects the torque of the torque motor, when the torque of the torque motor reaches the preset value, an in-place signal is generated, and the electronic control box 6 then controls the torque motor to stop working.

[0058] Since the structures of the first power module 72 and the second power module 73 are the same, the working principle of the second power module 73 will not be elaborated here.

[0059] Preferably, please refer to Figure 1 The paper cover applying device 4 includes a handling manipulator 41, a follow-up vacuum suction cup 42 provided at the clamping end of the handling manipulator 41, and a paper cover storage device 43. The handling manipulator 41 is used to drive the follow-up vacuum suction cup 42 to move, so that the follow-up vacuum suction cup 42 sucks the paper cover 93 on the paper cover storage device 43 and then covers it on one end of the coil material 92, and the paper cover 93 is concentric with the coil material. The handling manipulator 41 is preferably a six-axis manipulator; the paper cover storage device 43 includes a tray 431 and a plurality of railings 432 provided on the tray 431. A plurality of paper covers are stacked on the tray 431. The paper cover is a circular sheet; during the packaging process, the follow-up vacuum suction cup 42 always presses the paper cover against the end of the coil material, and the follow-up vacuum suction cup 42 can rotate with the rotation of the coil material without interfering with the handling manipulator 41.

[0060] The working principle is briefly described as follows: The staff first carry the coil to the material placement table 13, and then manually push the coil to roll backward. After the coil passes through the feeding table 11, it rolls into the packaging station 91 between the driving roller 22 and the driven roller 23. The coil is supported by the coil driving device 2 and remains stationary. Subsequently, the first distance measuring component 31 measures the distance between it and the left end of the coil, and the second distance measuring component 32 measures the distance between it and the right end of the coil. After the controller obtains the information of the first distance measuring component 31 and the second distance measuring component 32, it calculates the lateral position of the coil relative to the coil driving device 2 (i.e., the position points of the left end and the right end of the coil), as well as the width of the coil.

[0061] Then, the two paper cover feeding devices 4 move synchronously. The handling manipulator 41 drives the follower vacuum suction cup 42 to move, so that the follower vacuum suction cup 42 sucks the paper cover 93 on the paper cover storage device 43 and then covers it on one end of the coil 92. It is not until the packaging film winding is completed that the follower vacuum suction cup 42 releases the paper cover 93.

[0062] When starting to apply the film, the electric control box 6 controls the movement of the packaging film winding head 8 to the film application position according to the lateral position information of the coil material. The first power module 72 drives the packaging film winding head 8 to descend, so that the first pressure roller 834 and the second pressure roller 835 jointly press on the outer peripheral surface of the coil material. The coil material 92 exerts a reaction force on the first pressure roller 834 and the second pressure roller 835, and is transmitted to the first power module 72 through the packaging film winding head 8 and the cross beam 712, causing a change in the output torque of the first power module 72, thereby determining that the vertical movement of the packaging film winding head 8 is in place. At this time, the first pressure roller 834 and the second pressure roller 835 jointly press the coil material. Due to the action of the blowing rod 836, the first pressure roller 834 presses the packaging film 8331 tightly on the coil material 92; then the lifting drive device 826 drives the pressure wheel 825 to descend, so that the pressure wheel 825 presses against the outer peripheral surface of the coil material 92. The double-sided tape 827 unwinds under the traction of the pressure wheel 825. At this time, the double-sided tape 8271 located at the fixed glue line 828 is pasted on the coil material 92; the coil material drive device 2 and the winding mechanism 823 act simultaneously, and the double-sided tape coil on the double-sided tape 827 is pasted as the coil material rotates. When the pasting length of the double-sided tape 8271 reaches the preset length (5 - 10 cm), the braking mechanism 824 brakes and holds the double-sided tape 827, restricting the rotation of the double-sided tape 827 to stop the unwinding of the double-sided tape 827, and the winding mechanism 823 stops winding the isolation tape 8272. The double-sided tape 8271 is disconnected at the fixed glue line 828 under the traction and pulling action of the coil material. Then the lifting drive device 826 drives the pressure wheel 825 to rise away from the coil material. Subsequently, when the section of the double-sided tape 8271 is about to pass the first pressure roller 834, the film application drive device 837 starts, and the packaging film 8331 is also unfolded under the traction of the film application drive device 837 and adheres to the surface of the coil material 92. The packaging film 8331 is fixed on the coil material 92 through the double-sided tape 8271. After the packaging film 8331 winds around the coil material for several circles, it tightly holds the coil material 92. Subsequently, the first power module 72 drives the packaging film winding head 8 to lift away from the coil material 92, so that the first pressure roller 834 and the second pressure roller 835 leave the coil material 92. Then, according to the coil width information, the horizontal reciprocating movement winding stroke is determined. The second power module 73 drives the packaging film winding head 8 to move horizontally back and forth, so that the packaging film 8331 moves left and right on the coil material 92 for winding, and the paper cover 93 is also fixed on the coil material 92 under the winding of the packaging film. When the coil material 92 winds enough packaging film 9331, the second power module 73 and the coil material drive device 2 stop working. A section of taut packaging film is formed between the first pressure roller 834 and the coil material. Then the film cutting drive mechanism 842 drives the electric heating cutting strip 841 to swing around the axis of the first pressure roller 834 to cut the packaging film. The heated electric heating cutting strip 841 can quickly melt the packaging film.

[0063] Finally, the first power module 72 and the second power module 73 drive the wrapping film winding head 8 to reset to the initial position. Finally, the feeding device 5 pushes the wrapped coil 92 onto the blanking table 12, and the coil rolls to the discharging end of the blanking table 12, where the staff takes away the coil.

[0064] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution of the present invention and its inventive concept, and all such changes or substitutions should fall within the protection scope of the present invention.
