Description

Technical Field

[0001] The invention belongs to the technical field of coil packaging, and relates to an off-line slitting coil automatic discharging and packaging system. Background Art

[0002] At present, in order to prevent the coils from loosening and misalignment during transportation from the production line, the coils cut in the precision slitting unit of metal sheets are generally compressed and packaged online on the reel, and then the packaged coils are placed on the unloading trolley for weighing and then transported out of the reeling position by the unloading trolley. The online compression and packaging process requires the unit to stop production before the coils can be compressed, packaged, unloaded, weighed, and transported out in sequence. The unit needs to wait until the unloading trolley leaves the reeling position before it can restart and continue production and processing, which will inevitably greatly reduce the production efficiency of the unit. Summary of the invention

[0003] The object of the present invention is to provide an off-line slitting coil automatic discharging and packaging system in view of the above problems.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: An offline slitting coil automatic discharging and packaging system comprises a coil winding position, a coil weighing position, an offline coil packaging position, a first unloading trolley, a cross-arm coil storage position, a coil unloading position, a coil discharging position and a second unloading trolley. A cross material storage arm is provided in the cross-arm type coil storage position, and the cross material storage arm has four storage arms distributed along the cross. A first unloading trolley capable of moving back and forth between the coil rewinding position, the coil weighing position and the cross-arm type coil storage position is provided between the coil unloading position and the cross-arm type coil storage position, and a second unloading trolley capable of moving back and forth between the coil unloading position and the coil discharging position is provided between the coil unloading position and the cross-arm type coil storage position. The coil winding position, coil weighing position and cross-arm coil storage position are located on the first path, the coil unloading position and coil discharging position are located on the second path, and the first path is perpendicular to the second path.

[0005] The metal sheet precision slitting unit only stops running when the coiler is unloading. When the first unloading trolley unloads the slit coils from the coiler for transportation, the unit continues production. The slit coils can be weighed, pressed and packaged before leaving the production line, which greatly reduces the unit's downtime and effectively improves the unit's production efficiency. The first unloading trolley and the second unloading trolley can press the slit coils to prevent them from loosening and staggering and from tipping over during the transportation of the slit coils. The pressing and packaging of the slit coils in the coil offline packaging position can achieve synchronous pressing of each slit coil to avoid the situation where some coils are pressed tightly and some are pressed loosely. The cross storage arm rotates ninety degrees to rotate the storage arm storing the pressed slit coils to the coil unloading position, and at the same time rotates the empty storage arm to the coil offline packaging position, which can effectively improve the unloading efficiency. The second unloading trolley reciprocates on the second path to transport the pressed and packaged slit coils to the coil discharging position.

[0006] In the above-mentioned offline slitting coil automatic discharging and packaging system, the first path is provided with a first splicing track, a second splicing track and a third splicing track respectively located at the coil winding position, the coil weighing position and the coil offline packaging position, the first splicing track, the second splicing track and the third splicing track can be connected into one track and the first unloading trolley can stop on the first splicing track, the second splicing track and the third splicing track respectively, the coil weighing position is provided with a weighing device, and the second splicing track is fixed on the weighing device; The second path is provided with a fourth splicing track located at the coil unloading position and the coil discharging position, and the second unloading trolley can reciprocate along the fourth track between the coil unloading position and the coil discharging position.

[0007] The weighing device is arranged under the second splicing track. The weighing device can weigh the total weight of the second splicing track, the first unloading trolley and the slit coils, and indirectly obtain the precise weight of the slit coils by subtracting the fixed weight of the second splicing track and the first unloading trolley, thereby avoiding affecting the weighing accuracy and ensuring the weighing accuracy.

[0008] In the above-mentioned offline slitting coil material automatic discharging and packaging system, the first splicing track, the second splicing track and the third splicing track are respectively two parallel rail bodies, and the rail body includes a rail bottom, a rail waist and a rail head. There are notches on the rail waist and rail head at both ends of the rail body of the second spliced ​​rail. The rail waist and rail head of the rail bodies of the first spliced ​​rail and the third spliced ​​rail are provided with extension sections, which are arranged on the notch and do not contact the rail body of the second spliced ​​rail.

[0009] Notches are provided on the rail waist and rail head at both ends of the rail body of the second spliced ​​rail to facilitate the disassembly and assembly of the second spliced ​​rail and the installation of the weighing device. The extension sections on the rail waist and rail head of the rail bodies of the first spliced ​​rail and the third spliced ​​rail can ensure the continuity among the first spliced ​​rail, the second spliced ​​rail and the third spliced ​​rail, and ensure that the first unloading trolley can move stably for transportation.

[0010] In the above-mentioned offline slitting coil material automatic discharging and packaging system, the first unloading trolley and the second unloading trolley include a vehicle body, on which a lifting support platform is provided, the lifting support platform is connected to a lifting drive assembly of the support platform on one side, an anti-tilt bracket is provided at one end of the lifting support platform, and a buffer-type lifting and pressing unit is provided on one side of the top of the lifting support platform.

[0011] The lifting drive assembly of the material support platform can drive the lifting support platform to rise and support the slit coils. The buffered lifting and pressing unit on the top of the lifting support platform can synchronously press each slit coil on the lifting support platform to ensure that the slit coils will not have loose circles or staggered layers, and can avoid the situation where some coils are pressed tightly and some are pressed loosely. The anti-tilt bracket at one end of the lifting support platform can prevent the slit coils from tipping over, ensuring the stable transportation of the slit coils.

[0012] In the above-mentioned offline automatic discharging and packaging system for slitting coils, the buffer-type lifting and pressing unit includes a pressure beam, on which are provided a plurality of independent pressure bodies distributed axially along the slitting coils placed on the lifting and supporting platform, a first pressure spring is provided between the independent pressure bodies and the pressure beam, a pressure beam lifting assembly is provided between the pressure beam and the vehicle body, the pressure beam lifting assembly includes a Y-shaped bracket, the pressure beam is fixed to the inner side of the upper end of the Y-shaped bracket, the Y-shaped bracket is connected to the vehicle body through a vertical lifting guide unit, and a lifting cylinder is provided between the Y-shaped bracket and the vehicle body, and when the independent pressure bodies press the slitting coils and the pressure of the lifting cylinder reaches a preset value, the lifting cylinder stops pressing down.

[0013] The first compression spring can make the independent pressing body have a buffering function. When the lifting support platform rises to support the slit coil, the lifting cylinder can drive the pressure beam to descend. The descent of the pressure beam drives all the independent pressing bodies to press down. The independent pressing bodies press down to compact the corresponding slit coils. Since each independent pressing body has a buffering function and is independent of each other, each independent pressing body can adapt to the slight difference in diameter of the corresponding slit coil without damaging the surface of the slit coil, thereby achieving synchronous compaction of each slit coil, avoiding the situation where some coils are pressed tightly and some are pressed loosely, and ensuring that the slit coils will not have loose circles or staggered layers during transportation.

[0014] In the above-mentioned offline slitting coil automatic discharging and packaging system, a buffer-type pressing and packaging device is provided in the offline coil packaging position, and the buffer-type pressing and packaging device includes a bracket, a cross beam is provided below the bracket, and the cross beam is connected to the bracket through a vertical lifting assembly, and a plurality of pressing blocks arranged in the transverse direction are provided at the bottom of the cross beam, each pressing block is connected to the cross beam through an elastic member, and the elastic member can make the pressing block have a buffering function, and below the plurality of pressing blocks is a cross storage arm relative to the storage arm of the coil winding position.

[0015] The operation of the vertical lifting assembly drives the crossbeam down and drives all the pressing blocks to press down. The pressing blocks press down to compact the corresponding slit coils. Since each pressing block has a buffer function and is independent of each other, each pressing block can adapt to the slight difference in diameter of the corresponding slit coils without damaging the surface of the slit coils, thereby achieving synchronous compaction of each coil and avoiding the situation where some coils are compacted tightly and some are compacted loosely.

[0016] In the above-mentioned offline slitting coil material automatic discharging and packaging system, the elastic member comprises a second compression spring, the upper end of the second compression spring is fixed on the cross beam, and the lower end is fixed on the pressure block.

[0017] The two ends of the second compression spring are respectively connected to the crossbeam and the pressure block to give the pressure block a buffering function, so that each pressure block can adapt to the slight difference in diameter of the corresponding slit coils without damaging the surface of the slit coils, thereby achieving synchronous compression of each coil.

[0018] In the above-mentioned offline slitting coil material automatic discharging and packaging system, a guide structure is provided between the pressing block and the crossbeam.

[0019] The guide structure guides the pressing block in the vertical direction, preventing the pressing block from shaking and shifting when pressing down to cut the coil, thereby ensuring the pressing quality of the coil.

[0020] In the above-mentioned offline slitting coil automatic discharging and packaging system, the bracket includes an inverted concave frame spanning the offline packaging position of the coil for passing the first unloading trolley, and a 7-shaped frame is provided at one end of the inverted concave frame, one end of the 7-shaped frame is fixed on the inverted concave frame, and the other end is fixed to the top of the seat body of the cross storage arm, and the crossbeam is connected to the 7-shaped frame through a vertical lifting assembly.

[0021] The inverted concave frame and the 7-shaped frame form a three-point support with good support. The inverted concave frame is convenient for the unloading trolley to enter and exit for unloading. One end of the 7-shaped frame is fixed on the inverted concave frame, and the other end is fixed on the top of the seat body of the cross storage arm, making the overall structure more compact.

[0022] In the above-mentioned offline slitting coil automatic discharging and packaging system, the vertical lifting component includes a linear drive arranged on a 7-shaped frame, the driving end of the linear drive is connected to the crossbeam, and a lifting guide component is provided between the crossbeam and the 7-shaped frame. The lifting guide component includes two guide columns vertically arranged on the 7-shaped frame, and the lower end of the guide column is fixed on the crossbeam.

[0023] The driving end of the linear actuator can drive the crossbeam to descend vertically and drive all the pressure blocks to press down. The pressure blocks press down to compact the corresponding slit coils. During the vertical lifting of the crossbeam, the guide column shifts vertically on the 7-shaped frame, which plays a vertical guiding role for the crossbeam, ensuring that the crossbeam moves in the vertical direction, preventing the crossbeam from shaking and shifting, and ensuring the compaction quality of the slit coils.

[0024] Compared with the existing technology, the advantages of the present invention are: 1. The slit coils are weighed, pressed and packaged when they leave the production line, which greatly reduces the downtime of the unit, thereby effectively improving the production efficiency of the unit. 2. The slit coils will not fall over, loosen or stagger during transportation. 3. Each slit coil can be pressed synchronously without damaging the surface of the coil, which can avoid the situation where some coils are pressed tightly and some are pressed loosely, and the pressing quality of the coils is good.

DETAILED DESCRIPTION

[0027] Embodiment 1 like Figure 1-Figure 5 As shown, an offline slitting coil automatic discharging and packaging system comprises a coil winding position 1, a coil weighing position 2, a coil offline packaging position 3, a first unloading trolley 4, a cross-arm coil storage position 5, a coil unloading position 6, a coil discharging position 7 and a second unloading trolley 8. A cross storage arm 9 is arranged in the cross-arm coil storage position 5. The cross storage arm 9 has four storage arms 10 distributed along a cross. A storage arm 10 which can be arranged between the coil winding position 1 and the cross-arm coil storage position 5 is capable of sequentially loading and unloading the coils. A first unloading trolley 4 is provided between the coil unloading position 6 and the cross-arm coil storage position 5, and can reciprocate between the coil unloading position 6 and the coil discharging position 7 in sequence; the coil winding position 1, the coil weighing position 2 and the cross-arm coil storage position 5 are located on a first path 11, the coil unloading position 6 and the coil discharging position 7 are located on a second path 12, and the first path 11 is perpendicular to the second path 12.

[0028] In the present invention, after the coil is slit and coiled in the metal plate precision slitting unit, the unit stops running, the first unloading trolley 4 moves to the coil winding position 1 to unload the uncompressed and unpacked slit coil 13 from the coiler, and then transports the slit coil 13 from the coil winding position 1 to the coil weighing position 2 for weighing. When the slit coil 13 is transported away from the coil winding position 1, the unit restarts running and continues production and processing. After the slit coil 13 is weighed, the first unloading trolley 4 transports the slit coil 13 to the coil offline packaging position 3 so that the slit coil 13 is stored in the cross storage The arm 9 is relative to the storage arm 10 of the coil winding position 1, and the slit coil 13 is compacted and packaged in the coil offline packaging position 3. After the compaction process is completed, the cross storage arm 9 rotates the storage arm 10 storing the packaged slit coil 13 to the coil unloading position 6, and rotates the empty storage arm 10 to the coil offline packaging position 3, and then the first unloading trolley 4 moves back to the coil winding position 1 for unloading, and at the same time the second unloading trolley 8 moves to the coil unloading position 6 to transport the compacted and packaged slit coil 13 to the coil discharging position 7 for subsequent transfer operations.

[0029] The metal sheet precision slitting unit only stops running when the winder is unloading. When the first unloading trolley 4 unloads the slit coil 13 from the winder for transportation, the unit continues production. The slit coil 13 can be weighed, pressed and packaged before leaving the production line, which greatly reduces the unit's downtime and effectively improves the unit's production efficiency. During the process of transporting the slit coils 13, the first unloading trolley 4 and the second unloading trolley 8 can press the slit coils 13 to prevent the slit coils 13 from loosening and staggering and can prevent the slit coils 13 from tipping over. The slit coils 13 are pressed and packaged in the coil offline packaging position 3, which can achieve synchronous pressing of each slit coil 13 to avoid the situation where some coils are pressed tightly and some are pressed loosely. The cross storage arm 9 rotates ninety degrees to rotate the storage arm 10 storing the pressed slit coils 13 to the coil unloading position 6, and at the same time rotates the empty storage arm 10 to the coil offline packaging position 3, which can effectively improve the unloading efficiency. The second unloading trolley 8 reciprocates on the second path 12 to transport the pressed and packaged slit coils 13 to the coil discharging position 7.

[0030] Specifically, combined with Figure 1As shown, the first path 11 is provided with a first splicing track 14, a second splicing track 15 and a third splicing track 16 which are respectively located at the coil winding position 1, the coil weighing position 2 and the coil offline packaging position 3, the first splicing track 14, the second splicing track 15 and the third splicing track 16 can be connected into one track and the first unloading trolley 4 can stay on the first splicing track 14, the second splicing track 15 and the third splicing track 16 respectively, the coil weighing position 2 is provided with a weighing device 17, and the second splicing track 15 is fixed on the weighing device 17; the second path 12 is provided with a fourth splicing track 18 which is located at the coil unloading position 6 and the coil discharging position 7, and the second unloading trolley 8 can reciprocate along the fourth track 18 between the coil unloading position 6 and the coil discharging position 7.

[0031] The first unloading trolley 4 can reciprocate along the track formed by the first splicing track 14, the second splicing track 15 and the third splicing track 16 to transport the slit coils 13. The weighing device 17 is arranged under the second splicing track 15. The weighing device 17 can weigh the total weight of the second splicing track 15, the first unloading trolley 4 and the slit coils 13, and by subtracting the fixed weight of the second splicing track 15 and the first unloading trolley 4, the precise weight of the slit coils 13 can be indirectly obtained, thereby avoiding affecting the weighing accuracy and ensuring the weighing accuracy.

[0032] The second unloading trolley 8 can reciprocate along the fourth track 18 between the coil unloading position 6 and the coil discharging position 7 to transport the compacted and packaged slit coils 13.

[0033] Specifically, combined with Figure 1 As shown, the first spliced ​​track 14, the second spliced ​​track 15 and the third spliced ​​track 16 are respectively two parallel rail bodies 19, the rail body 19 includes a rail bottom 20, a rail waist and a rail head 21, and notches 22 are provided on the rail waist and the rail head 21 at both ends of the rail body 19 of the second spliced ​​track 15, and extension sections 23 are provided on the rail waist and the rail head 21 of the rail bodies 19 of the first spliced ​​track 14 and the third spliced ​​track 16. The extension section 23 is arranged on the notch 22 and does not contact the rail body 19 of the second spliced ​​track 15.

[0034] The fourth spliced ​​rail 18 is composed of two rail bodies 19 parallel to each other. The rail body 19 includes a rail bottom 20 , a rail waist and a rail head 21 .

[0035] Both sides of the bottom ends of the first unloading trolley 4 and the second unloading trolley 8 are provided with moving wheels 51 that match with the corresponding rail bodies 19 .

[0036] Notches 22 are provided on the rail waist and rail head 21 at both ends of the rail body 19 of the second spliced ​​rail 15 to facilitate the disassembly and assembly of the second spliced ​​rail 15 and the installation of the weighing device 17. The extension sections 23 on the rail waist and rail head 21 of the rail body 19 of the first spliced ​​rail 14 and the third spliced ​​rail 16 can ensure the continuity between the first spliced ​​rail 14, the second spliced ​​rail 15, and the third spliced ​​rail 16, and ensure that the first unloading trolley 4 can move stably for transportation.

[0037] Specifically, combined with Figure 2 and Figure 3 As shown, the first unloading trolley 4 and the second unloading trolley 8 include a vehicle body 24, on which a lifting supporting platform 25 is provided. The lifting supporting platform 25 is connected to a supporting platform lifting drive assembly 26 on one side, and an anti-tilt bracket 27 is provided at one end of the lifting supporting platform 25. A buffered lifting and pressing unit 28 is provided on one side of the top of the lifting supporting platform 25.

[0038] The material support platform lifting drive assembly 26 can drive the lifting support platform 25 to rise and support the slit coils 13. The buffered lifting and pressing unit 28 on the top of the lifting support platform 25 can synchronously press each slit coil 13 on the lifting support platform 25 to ensure that the slit coils 13 will not have loose circles and staggered layers, and can avoid the situation where some coils are pressed tightly and some are pressed loosely. The anti-tilt bracket 27 on one end of the lifting support platform 25 can prevent the slit coils 13 from tipping over, thereby ensuring the stable transportation of the slit coils 13.

[0039] Specifically, combined with Figure 2 and Figure 3 As shown, the buffer-type lifting and pressing unit 28 includes a pressing beam 29, on which a plurality of independent pressing bodies 30 are arranged axially distributed along the slitting coil 13 placed on the lifting supporting platform 25, a first pressing spring is arranged between the independent pressing body 30 and the pressing beam 29, a pressing beam lifting assembly 31 is arranged between the pressing beam 29 and the vehicle body 24, and the pressing beam lifting assembly 31 includes a Y-shaped bracket 32, on the inner side of the upper end of the Y-shaped bracket 32, the Y-shaped bracket 32 ​​is connected to the vehicle body 24 through a vertical lifting guide unit 33, and a lifting cylinder 34 is arranged between the Y-shaped bracket 32 ​​and the vehicle body 24, when the independent pressing body 30 presses the slitting coil 13 and the pressure of the lifting cylinder 34 reaches a preset value, the lifting cylinder 34 stops pressing down.

[0040] The first compression spring enables the independent compression body 30 to have a buffering function.

[0041] When the lifting platform 25 rises to support the slitting coil 13, the lifting cylinder 34 drives the Y-shaped bracket 32 ​​to descend vertically and simultaneously drives the pressure beam 29 on the inner side of the upper end of the Y-shaped bracket 32 ​​to descend. The descent of the pressure beam 29 drives all the independent pressure bodies 30 to press down. The independent pressure bodies 30 press down to compress the corresponding slitting coils 13. When the compressed slitting coils 13 reach the control pressure, the lifting cylinder 34 stops pressing down and the pressure beam 29 stops descending. Since each independent pressure body 30 has a buffering function and is independent of each other, each independent pressure body 30 can adapt to the slight difference in diameter of the corresponding slitting coil 13 without damaging the surface of the slitting coil 13, thereby achieving synchronous compression of each slitting coil 13, avoiding the situation where some coils are pressed tightly and some are pressed loosely, and ensuring that the slitting coils 13 will not have loose circles or staggered layers during transportation.

[0042] Before the first unloading trolley 4 enters the coil winding position 1, the lifting support platform 25 descends to the lowest position and the Y-shaped bracket 32 ​​rises to the highest position. At this time, the slit coil 13 is on the core shaft 35 of the winder, and the pressure roller 36 of the winder presses on the slit coil 13; when the first unloading trolley 4 moves into the coil winding position 1, the sensor sends an in-position signal, and the support platform lifting drive assembly 26 drives the lifting support platform 25 to rise and support the slit coil 13, and the lifting cylinder 34 drives the pressure beam 29 to descend so that all independent pressure bodies 30 press down to press the corresponding slit coils 13, and then the pressure roller 36 of the winder is lifted, and the first unloading trolley 4 moves out of the coil winding position 1 to complete automatic unloading.

[0043] Specifically, combined with Figure 1 , Figure 4 and Figure 5 As shown, a buffer-type pressing and packaging device 37 is provided in the offline packaging position 3 for coiled materials. The buffer-type pressing and packaging device 37 includes a bracket 38, a cross beam 39 is provided below the bracket 38, the cross beam 39 is connected to the bracket 38 through a vertical lifting assembly 40, a plurality of pressing blocks 41 arranged in the transverse direction are provided at the bottom of the cross beam 39, each pressing block 41 is connected to the cross beam 39 through an elastic member 42, the elastic member 42 can make the pressing block 41 have a buffering function, and below the plurality of pressing blocks 41 is a cross storage arm 9 relative to the storage arm 10 of the coiled material winding position 1.

[0044] The first unloading trolley 4 transports the slit coil 13 to the coil offline packaging position 3 so that the slit coil 13 is stored on the storage arm 10 of the cross storage arm 9 relative to the coil winding position 1 and then moves back to the coil winding position 1. Subsequently, the vertical lifting assembly 40 drives the cross beam 39 to descend. When the cross beam 39 descends, it drives all the pressing blocks 41 to press down. The pressing blocks 41 press down to press the corresponding slit coils 13. When the slit coils 13 are pressed to reach the control pressure, the vertical lifting assembly 40 stops running and the cross beam 39 stops descending. Since each pressing block 41 has a buffer function and is independent of each other, each pressing block 4 1 can adapt to the slight difference in diameter of the corresponding slit coils 13, and at the same time do not damage the surface of the slit coils 13, so as to achieve synchronous compression of each coil, and avoid the situation that some coils are compressed tightly and some are compressed loosely. After the slit coils 13 are compressed, the vertical lifting assembly 40 drives the crossbeam 39 to reset, and then the slit coils 13 are mechanically or manually packaged by the packaging equipment, and the packaging equipment is the existing technology. Finally, the cross storage arm 9 rotates to rotate the storage arm 10 storing the packaged slit coils 13 to the coil unloading position 6, and at the same time rotates the empty storage arm 10 to the coil offline packaging position 3.

[0045] Specifically, combined with Figure 4 As shown, the elastic member 42 includes a second compression spring, the upper end of which is fixed on the cross beam 39 , and the lower end of which is fixed on the pressure block 41 .

[0046] The two ends of the second compression spring are respectively connected to the cross beam 39 and the pressure block 41, so that the pressure block 41 has a buffering function, so that each pressure block 41 can adapt to the slight difference in diameter of the corresponding slit coil 13 without damaging the surface of the slit coil 13, thereby achieving synchronous compression of each coil.

[0047] Specifically, combined with Figure 4 As shown, a guide structure 43 is provided between the pressing block 41 and the cross beam 39 , and the guide structure 43 includes a guide rod fixed to the bottom of the cross beam 39 , one end of the guide rod is fixed to the cross beam 39 , and the other end is inserted into the guide rod hole of the pressing block.

[0048] The guide rod is inserted into the guide rod hole of the pressing block 41. The guide rod cooperates with the guide rod hole to guide the pressing block 41 in the vertical direction, avoiding shaking and displacement when the pressing block 41 presses down the slitting coil 13, thereby ensuring the pressing quality of the coil.

[0049] Specifically, combined with Figure 1 , Figure 4 and Figure 5As shown, the bracket 38 includes an inverted concave frame 44 spanning the offline packaging position 3 for the coil to pass the first unloading trolley 4, and a 7-shaped frame 45 is provided at one end of the inverted concave frame 44. One end of the 7-shaped frame 45 is fixed to the inverted concave frame 44, and the other end is fixed to the top of the base body of the cross storage arm 9. The crossbeam 39 is connected to the 7-shaped frame 45 through a vertical lifting assembly 40.

[0050] The inverted concave frame 44 and the 7-shaped frame 45 form a three-point support with good support performance. The inverted concave frame 44 is convenient for the unloading trolley to enter and exit for unloading. One end of the 7-shaped frame 45 is fixed on the inverted concave frame 44, and the other end is fixed on the top of the seat body of the cross storage arm 9, making the overall structure more compact.

[0051] Specifically, combined with Figure 4 and Figure 5 As shown, the vertical lifting assembly 40 includes a linear drive 46 arranged on a 7-shaped frame 45, and the driving end of the linear drive 46 is connected to the cross beam 39. A lifting guide assembly 47 is provided between the cross beam 39 and the 7-shaped frame 45. The lifting guide assembly 47 includes two guide columns 48 vertically arranged on the 7-shaped frame 45, and the lower end of the guide column 48 is fixed on the cross beam 39.

[0052] The linear drive 46 includes a cylinder 49 , which is fixed on the 7-shaped frame 45 , and a piston rod 50 of the cylinder 49 is hinged on the crossbeam 39 .

[0053] The piston rod 50 of the oil cylinder 49 is pushed out to drive the cross beam 39 to descend vertically, thereby driving all the pressing blocks 41 to press down, and the pressing blocks 41 press down to compress the corresponding slit coils 13 .

[0054] During the vertical lifting of the beam 39, the guide column 48 is vertically displaced on the 7-shaped frame 45, which plays a role in vertically guiding the beam 39, ensuring that the beam 39 moves in the vertical direction, preventing the beam 39 from shaking and shifting, and ensuring the compression quality of the slit coil 13.

[0055] The working principle of the present invention is as follows: after the first unloading trolley 4 moves into the coil winding position 1, the sensor sends out an arrival signal, and the lifting drive assembly 26 of the supporting platform drives the lifting supporting platform 25 to rise and hold the slit coil 13, and the lifting cylinder 34 drives the pressure beam 29 to descend so that all independent pressure bodies 30 press down to press the corresponding slit coils 13, and then the pressure roller 36 of the coiler is lifted, and the first unloading trolley 4 moves out of the coil winding position 1 to transport the slit coil 13 to the coil weighing position 2 for weighing; the weighing device 17 can weigh the total weight of the second splicing track 15, the first unloading trolley 4 and the slit coil 13, and by subtracting the fixed weight of the second splicing track 15 and the first unloading trolley 4, the precise weight of the slit coil 13 is indirectly obtained; After the weighing of the slit coil 13 is completed, the first unloading trolley 4 transports the slit coil 13 to the coil offline packaging position 3 so that the slit coil 13 is stored on the storage arm 10 of the cross storage arm 9 relative to the coil winding position 1. After the sensor sends an in-place signal, the piston rod 50 of the oil cylinder 49 is pushed out to drive the cross beam 39 to descend vertically, driving all the pressure blocks 41 to press down. When the slit coil 13 is pressed to reach the control pressure, the cross beam 39 stops descending, and each pressure block 41 is buffered by the second compression spring. It can adapt to the slight difference in diameter of the corresponding slit coils 13, and at the same time, it can avoid damaging the surface of the slit coils 13, and finally realize the synchronous compression of each slit coil 13; after the slit coils 13 are compressed, the oil cylinder 49 drives the crossbeam 39 to reset, and then the slit coils 13 are packaged, and finally the cross storage arm 9 rotates to rotate the storage arm 10 storing the packaged slit coils 13 to the coil unloading position 6, and at the same time rotates the empty storage arm 10 to the coil offline packaging position 3; Then the second unloading trolley 8 moves to the coil unloading position 6 to transport the compacted and packaged slit coils 13 to the coil discharging position 7 for subsequent transfer operations.

[0056] Embodiment 2 The structure and working principle of this embodiment are substantially the same as those of the first embodiment, except that the guide structure 43 includes a guide slot disposed at the bottom of the crossbeam 39, and the pressing block 41 is disposed in the guide slot.

[0057] The pressing block 41 is arranged in the guide slot, and the guide slot guides the pressing block 41 in the vertical direction to avoid shaking and displacement when the pressing block 41 presses down the coil, thereby ensuring the pressing quality of the coil.
