Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an automatic winding core supply component. Background Art

[0002] With the continuous development of solar power generation technology, solar panels are being widely used in production. Solar cell encapsulation film (EVA film), used between laminated glass, is a key material in the production of solar panels. Solar EVA film is typically extruded through an extruder and then cast into a thin film. After extrusion and casting, the film needs to be wound up. Typically, after extrusion and shaping, the film is wound onto a core, which is typically mounted on an air-inflating shaft. After winding, the film-wrapped core needs to be removed from the air-inflating shaft and replaced with a new one. Due to the length of the cores, they are typically stacked on one side and manually removed from the stack. Chinese Patent Publication No. CN203806851 U discloses an automatic pneumatic paper roll loading device equipped with a paper roll box to hold the paper rolls. The device utilizes an inclined surface at the bottom of the box to automatically discharge the paper rolls. However, due to the long overall length of the paper rolls, the paper rolls are easily stacked in the paper roll box and arranged crosswise, which makes it difficult to output the paper rolls smoothly, resulting in low reliability. In view of this, how to design a technology for smoothly outputting paper rolls to improve reliability is the technical problem to be solved by the utility model. Utility Model Content

[0003] The utility model provides an automatic roll core supply component, which enables the automatic roll core supply component to smoothly output a paper roll, thereby improving the reliability of use.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides an automatic core supply assembly, comprising:

[0006] Support frame;

[0007] A material box, comprising a storage bin and a conveying channel, wherein a connecting port is provided at the bottom of the storage bin, the conveying channel is vertically arranged and arranged on the connecting port, and a switchable discharge port is provided at the bottom of the conveying channel;

[0008] A toggle module, the toggle module includes a toggle rod, two connecting rods and a toggle drive component, the toggle rod is connected between the two connecting rods; the connecting rod and the toggle rod are located in the storage bin, the upper end of the connecting rod is hinged on the storage bin, the toggle rod is close to the connecting port and extends along the length direction of the connecting port, and the toggle drive component is configured to drive the connecting rod to rotate.

[0009] The technical solution of the present invention has the following technical effects compared with the existing technology: the winding core at the bottom of the storage bin is moved by the toggling module, and the toggling driving component drives the toggling rod to move up and down at the connecting port through the connecting rod to toggle and comb the winding core at the connecting port; and because the toggling rod extends along the length direction of the connecting port, the toggling action of the toggling rod allows the crossed winding cores to be combed smoothly to solve the problem of cross-blocking of the winding cores, ensuring that the winding cores can be smoothly output to improve reliability of use.

[0027] Example 1, as Figure 1-Figure 2 As shown, this embodiment provides an automatic film winding and loading and unloading system, including a winder 1. The winder 1 is capable of automatically winding a film that requires winding. The winder 1 needs to cooperate with an air-expanding shaft 4 during winding. That is, a winding core 200 is mounted on the air-expanding shaft 4, and the film is wound around the winding core 200. A conventional winder 1 typically includes a friction roller 12 and a reel drive module 13. The friction roller 12 winds the film around the reel core 200 of the air-expanding shaft 4, while the reel drive module drives the air-expanding shaft 4 to rotate to rewind the reel core 200. The specific structure of the winder 1 to achieve film winding is not limited here, and the structure of the winder 1 in conventional technology can be adopted.

[0028] In order to automatically load and unload the air shaft 4 and automatically remove the wound film roll 100 from the air shaft 4 and replace it with a new winding core 200, the winding machine 1 needs to be structurally improved and equipped with a lifting module 14. The lifting fixture configured by the lifting module 14 is used to load or unload the air shaft 4. On the other hand, the automatic film winding and loading and unloading system further includes an automatic loading and unloading device 2, which is used to automatically remove the film roll 100 from the air shaft 4 and replace the air shaft 4 with a new winding core 200. The specific structural configuration of the automatic film winding and loading and unloading system is described below with reference to the accompanying drawings.

[0029] like Figure 3-Figure 5As shown, the winder 1 includes a frame 11, a friction roller 12, a reel drive module 13 and a lifting module 14. The friction roller 12 is rotatably arranged on the frame 11. The reel drive module 13 has a power output component (such as a gear). The power output component is rotatably arranged on the frame 11 and is located on one side of the friction roller 12. The power output component is configured to drive the air shaft 4 to rotate on one side of the friction roller 12 to wind the film roll 100 on the core 200 of the air shaft 4. The lifting module 14 is provided with a lifting clamp, and the lifting clamp can move relative to the frame 11.

[0030] The automatic loading and unloading equipment 2 includes a loading and unloading frame 21, a sliding frame 22, a supporting frame 23, an inflation and deflation assembly 24 and a supply assembly 25; the inflation and deflation assembly 24 is arranged at one end of the loading and unloading frame 21 and is configured to clamp the air-expanding shaft 4 and inflate or deflate the air-expanding shaft 4, the sliding frame 22 is slidably arranged on the loading and unloading frame 21, the supporting frame 23 is arranged on the sliding frame 22, and the supply assembly 25 includes a support frame 251 and a material box 252, and the bottom of the material box 252 is provided with a switchable discharge port 2521, the support frame 251 is arranged on the loading and unloading frame 21 and away from the inflation and deflation assembly 24, and the material box 252 is arranged on the support frame 251.

[0031] Specifically, for the winder 1, it is additionally equipped with a lifting module 14 to realize automatic loading and unloading of the air shaft 4. The lifting clamp configured by the lifting module 14 can lift the air shaft 4, so that the core 200 on the air shaft 4 is lifted from the frame 11 to the automatic loading and unloading equipment 2 after completing the winding to form the film roll 100. The air shaft 4 with a new core 200 assembled in the automatic loading and unloading equipment 2 can also be lifted and recovered into the winder 1.

[0032] In order to meet the requirement of automatic loading and unloading of the core 200 on the air-expanding shaft 4 , the packaging and transfer equipment 3 must be able to automatically unwind the core 200 with the film wound on the air-expanding shaft 4 , and then load a new core 200 onto the air-expanding shaft 4 .

[0033] To this end, for the air-inflating shaft 4 wound to form the film roll 100 unloaded from the winder 1, the film roll 100 is connected to the air-inflating shaft 4 and placed on the support bracket 23, and then the inflation and deflation component 24 can clamp the air-inflating shaft 4 and deflate the air-inflating shaft 4.

[0034] After the inflatable shaft 4 is deflated, the sliding frame 22 slides in the direction away from the inflation and deflation component 24, so that the winding core 200 connecting the diaphragm is detached from the inflatable shaft 4, and the inflatable shaft 4 is clamped by the inflation and deflation component 24 to keep one end suspended.

[0035] When the film roll 100 on the support frame 23 on the sliding frame 22 leaves the air inflation shaft 4, the film roll 100 can be unloaded from the automatic loading and unloading equipment 2 to free up the support frame 23. At this time, the supply component 25 can supply a new roll core 200 from the material box 252 to the support frame 23.

[0036] After a new winding core 200 is placed on the support frame 23, the sliding frame 22 moves back toward the inflation / deflation assembly 24, allowing the winding core 200 on the support frame 23 to be again placed on the inflatable shaft 4. The inflation / deflation assembly 24 then re-inflates the inflatable shaft 4, securing the winding core 200 on the inflatable shaft 4. At this point, the inflatable shaft 4 on the support frame 23 can be hoisted back to the frame 11 of the winder 1 using the hoisting module 14 for standby use.

[0037] In one embodiment of the present application, the following structural design and improvement are carried out for the specific structural form of the hoisting module 14 in the winder 1. Figure 3-Figure 5 Provide explanation.

[0038] like Figure 3-Figure 5 As shown, the hoisting module 14 includes a loading assembly 141 , and the hoisting fixture includes a loading fixture 142 ;

[0039] The loading assembly 141 includes a lifting bracket 1411 and a synchronous moving assembly 1412, the synchronous moving assembly 1412 includes a synchronous shaft 14121, multiple synchronous wheels 14122, two synchronous belts 14123 and a synchronous driving component 14124, the four corners of the lifting bracket 1411 are respectively provided with the synchronous wheels 14122, wherein a pair of oppositely arranged synchronous wheels 14122 are connected by the synchronous shaft 14121, the synchronous belt 14123 is wound around the two synchronous wheels 14122 on the corresponding sides, and the synchronous driving component 14124 is configured to drive the synchronous shaft 14121 to rotate; the loading fixture 142 is arranged on the synchronous belt 14123, and the lifting bracket 1411 is fixed on the top of the frame 11.

[0040] Specifically, the pneumatic shaft 4, equipped with a new winding core 200, can be clamped by the loading fixture 142 and, in conjunction with the loading assembly 141, moved and hoisted onto the frame 11 for standby use. A hoisting bracket 1411 is mounted on top of the frame 11, and a synchronous belt 14123 drives the loading fixture 142 back and forth to facilitate hoisting of the pneumatic shaft 4.

[0041] Furthermore, for the loading fixture 142, in order to facilitate the lifting of the pneumatic shaft 4, the loading fixture 142 includes a hanging beam 1421, a guide rod 1422, a lifting cylinder 1423, a driving cylinder 1424, a connecting seat 1425 and a hook 1426. The hanging beam 1421 can be slidably arranged on the lifting bracket 1411 and connected to the synchronous belt 14123. The guide rod 1422 is upright on the hanging beam 1421. The connecting seat 1425 can be slidably arranged on the guide rod 1422. The lifting cylinder 1423 is arranged between the hanging beam 1421 and the connecting seat 1425. The hook 1426 is rotatably arranged on the connecting seat 1425. The driving cylinder 1424 is hinged between the hook 1426 and the connecting seat 1425.

[0042] Specifically, the loading fixture 142 can follow the movement of the loading assembly 141 to facilitate the loading and unloading of the pneumatic shaft 4. When loading the pneumatic shaft 4, the loading fixture 142 follows the movement of the synchronous belt 14123, extending the loading fixture 142 to the outside of the frame 11. The lifting cylinder 1423 then lowers the connecting base 1425, positioning the hooks 1426 below the ends of the pneumatic shaft 4. The driving cylinder 1424 then rotates the hooks 1426, securing the pneumatic shaft 4. The lifting cylinder 1423 then raises the connecting base 1425. The synchronous belt 14123 then reverses the movement of the loading fixture 142, moving the pneumatic shaft 4 to its storage position above the frame 11. The driving cylinder 1424 then reverses the rotation of the hooks 1426, releasing the pneumatic shaft 4, which is then placed on the frame 11 for future use.

[0043] Furthermore, in order to automatically unload the film roll 100 connected to the air-inflated shaft 4 after winding from the frame 11 , the hoisting module 14 further includes an unloading component 143 , and the hoisting fixture includes an unloading fixture 144 .

[0044] The unloading assembly 143 includes an unloading drive component 1431 and a connecting shaft 1432, and the unloading clamp 144 includes two lifting arms 1441. The lower ends of the two lifting arms 1441 are respectively arranged at the corresponding ends of the connecting shaft 1432, and the upper ends of the lifting arms 1441 are provided with a lifting slot 1442; the connecting shaft 1432 is rotatably arranged on the frame 11, and the unloading drive component 1431 is configured to drive the connecting shaft 1432 to rotate.

[0045] Specifically, the two side-by-side lifting arms 1441 of the unloading fixture 144 are fixedly mounted on the same connecting shaft 1432, and the connecting shaft 1432 can be driven to rotate on the frame 11 by the unloading driving component 1431, so that the lifting arms 1441 can swing up and down following the connecting shaft 1432.

[0046] In actual use, when the reel drive module 13 drives the air expansion shaft 4 to rotate and completes the winding of the film sheet around the upper core 200, the air expansion shaft 4, connected to the film roll 100, is detached from the reel drive module 13 and supported by the lifting arm 1441. The two ends of the air expansion shaft 4 are clamped in the corresponding lifting slots 1442. At this time, the air expansion shaft 4 and the film roll 100 are supported on the lifting arm 1441, and the unloading drive component 1431 drives the connecting shaft 1432 to rotate, so that the lifting arm 1441 drives the air expansion shaft 4 and the film roll 100 to move downward to realize the unloading operation.

[0047] Furthermore, in order to ensure that the pneumatic shaft 4 can automatically roll onto the lifting arm 1441 after completing the winding and disengaging from the reel drive module 13, the frame 11 is provided with transversely arranged slide rails 15 on both sides, and the reel drive module 13 is slidably set on the slide rails 15. The surface of the outer end of the slide rail 15 forms an inclined rail surface 151, and the inclined rail surface 151 extends downwardly toward the lifting arm 1441.

[0048] Specifically, conventional technology utilizes a motor-driven drive gear in the reel drive module 13 to rotate the pneumatic shaft 4. This gear engages the driven gear on the pneumatic shaft 4, achieving rotation. After the reeling operation is completed on the pneumatic shaft 4, the drive gear in the reel drive module 13 disengages from the driven gear on the pneumatic shaft 4. The pneumatic shaft 4, freed from the reel drive module 13, falls onto the inclined track surface 151. Because the inclined track surface 151 is inclined and tilts downward toward the lifting arm 1441, the pneumatic shaft 4 automatically slides along the inclined track surface 151 toward the lifting arm 1441 under its own weight, allowing the lifting arm 1441 to automatically unload the reel.

[0049] In another embodiment of the present application, for the automatic loading and unloading device 2, it needs to meet the requirements of the air shaft 4 automatically removing the winding core 200 and automatically loading the winding core 200. For the specific structural form of the automatic loading and unloading device 2, combined with the attached Figures 6-11 Provide explanation.

[0050] The automatic loading and unloading device 2 includes a loading and unloading frame 21, a sliding frame 22, a supporting frame 23, an inflation and deflation assembly 24, and a supply assembly 25. The inflation and deflation assembly 24 is disposed at one end of the loading and unloading frame 21. The inflation and deflation assembly 24 can clamp the inflatable shaft 4 unloaded from the lifting module 14 and can also inflate and deflate the inflatable shaft 4 as needed.

[0051] The sliding frame 22 can drive the supporting part to slide back and forth between the inflation and deflation assembly 24 and the supply assembly 25. The supporting frame 23 is arranged on the sliding frame 22 and is used to support the inflation shaft 4 and the film roll 100 and is also used to carry the new roll core 200. The supply assembly 25 includes a support frame 251 and a material box 252. The material box 252 is used to hold the new roll core 200, and a switchable discharge port 2521 is provided at the bottom of the material box 252 to feed the new roll core 200 through the discharge port 2521. The support frame 251 is arranged on the loading and unloading frame 21 and away from the inflation and deflation assembly 24. The material box 252 is arranged on the support frame 251.

[0052] Specifically, when the air-inflating shaft 4 is wound, the sliding frame 22 moves to the inflation and deflation assembly 24, and the air-inflating shaft 4 connected to the film roll 100 are placed on the support frame 23. At the same time, the inflation and deflation assembly 24 will clamp the corresponding end of the air-inflating shaft 4 to deflate the air-inflating shaft 4.

[0053] After the air shaft 4 is deflated, the core 200 in the film roll 100 can be easily detached from the air shaft 4. At this time, the sliding frame 22 moves away from the inflation and deflation component 24, and the air shaft 4 is still clamped by the inflation and deflation component 24, while the film roll 100 follows the support frame 23 to move and gradually detaches from the air shaft 4 along the axial direction of the air shaft 4.

[0054] After the film roll 100 is unloaded from the air shaft 4, the film roll 100 on the support bracket 23 can be removed from the automatic loading and unloading device 2. The material box 252 in the supply assembly 25 then opens its discharge port 2521, allowing a core 200 in the material box 252 to drop onto the support bracket 23. The support bracket 23 is moved toward the inflation assembly 24 via the sliding frame 22, allowing the core 200 on the support bracket 23 to be placed on the air shaft 4 again. After the new core 200 is placed on the air shaft 4, the inflation assembly 24 inflates the air shaft 4, ensuring that the new core 200 is securely tightened on the air shaft 4 for rewinding.

[0055] By configuring the inflation and deflation component 24 and the supply component 25, on the one hand, the inflation and deflation component 24 can also inflate and deflate the air shaft 4 to meet the requirements of unloading the film roll 100 and loading the new roll core 200. On the other hand, the inflation and deflation component 24 can clamp the air shaft 4 to ensure that the air shaft 4 is effectively supported after the film roll 100 is detached from the air shaft 4 and meet the requirements of loading the new roll core 200. At the same time, the sliding frame 22 drives the supporting frame 23 to move, and the supporting frame 23 can unload the film roll 100 and move the new roll core 200 to be assembled on the air shaft 4, thereby realizing automatic loading and unloading of the air shaft 4 without manual participation, thereby improving the degree of automated operation and reducing the labor intensity of workers, so as to improve production efficiency.

[0056] Furthermore, the inflation and deflation assembly 24 must meet the requirements of inflation and deflation and clamping support of the inflatable shaft 4. To this end, the inflation and deflation assembly 24 includes an inflation and deflation base 241, an inflation and deflation component 242, two clamping components 243, a clamping drive component 244, and a reciprocating drive component 245. The two clamping components 243 are arranged opposite to each other, and the clamping drive component 244 is configured to drive the two clamping components 243 to slide relative to each other on the inflation and deflation base 241. The inflation and deflation component 242 is located between the two clamping components 243, and the reciprocating drive component 245 is configured to drive the inflation and deflation component 242 to slide on the inflation and deflation base 241.

[0057] The inflation and deflation component 242 is provided with a first air vent 2421 and a second air vent 2422 that are interconnected. The first air vent 2421 is arranged at the free end of the inflation and deflation component 242, and the second air vent 2422 is configured to connect to an inflator; wherein the inflation and deflation base 241 is provided on the loading and unloading rack 21.

[0058] Specifically, two relatively arranged clamping parts 243 are configured on the inflation and deflation base 241. The two clamping parts cooperate with each other to clamp and support the inflatable shaft 4, and the two clamping parts are driven relatively close or away by the clamping drive part 244 (such as a cylinder or an electric push rod). Both clamping parts can be moved, or one of the clamping parts can be fixed and the other clamping part moves.

[0059] After the inflatable shaft 4 and the film roll 100 are placed on the support bracket 23, the end of the inflatable shaft 4 will be located between the two clamping components, and the clamping drive component 244 drives the two clamping components to clamp the inflatable shaft 4 therebetween, so that the inflatable shaft 4 can be clamped and supported by the clamping component 243.

[0060] After the inflatable shaft 4 is clamped, the inflation / deflation component 242, driven by a reciprocating drive component 245 (such as a cylinder or electric push rod), moves toward the end of the inflatable shaft 4, aligning with the inflation / deflation hole of the inflatable shaft 4. This allows the first vent hole 2421 to communicate with the internal air cavity of the inflatable shaft 4, while the inflator connected to the second vent hole 2422 communicates with the outside air when not inflating, thereby deflating the inflatable shaft 4.

[0061] When a new winding core 200 is replaced on the inflatable shaft 4 , the inflator inflates the second vent hole 2422 to inject gas into the air cavity of the inflatable shaft 4 . After the inflatable shaft 4 expands, the winding core 200 is fixed on the inflatable shaft 4 .

[0062] In order to improve the support reliability of the gas-expanding shaft 4 , an unloading card plate 246 is further provided on the inflation and deflation base 241 , and a supporting groove for positioning the gas-expanding shaft 4 is provided on the unloading card plate 246 .

[0063] Specifically, after the pneumatic shaft 4 and film roll 100 are placed on the support bracket 23, the end of the pneumatic shaft 4 is positioned between the two clamping components. Simultaneously, the pneumatic shaft 4 is clamped in the support groove of the unloading clamp 246. After the end of the pneumatic shaft 4 is clamped by the two clamping components, the unloading clamp 246 further supports the pneumatic shaft 4, forming a two-point support on the pneumatic shaft 4, thereby improving the support reliability of the pneumatic shaft 4.

[0064] Correspondingly, the pneumatic shaft 4 may be provided with an annular positioning groove 45 to cooperate with the unloading card plate 246, so that the unloading card plate 246 can be stuck in the annular positioning groove 45 to limit the pneumatic shaft 4 in the axial direction.

[0065] Furthermore, in order to improve the clamping reliability of the pneumatic shaft 4, a clamping groove (not marked) is provided on the clamping component, and a clamping space is formed between the two clamping grooves; after the pneumatic shaft 4 is clamped by the two clamping components, the pneumatic shaft 4 is located in the two clamping grooves.

[0066] Specifically, when the pneumatic shaft 4 is clamped by a clamping component, in order to effectively locate the position of the pneumatic shaft 4, a clamping groove can be provided on the clamping component. The contour of the clamping groove matches the outer contour of the pneumatic shaft 4. The pneumatic shaft 4 is clamped in the clamping groove to ensure that the pneumatic shaft 4 can be accurately positioned and effectively clamped and supported.

[0067] Furthermore, a supporting groove 231 is formed on the supporting bracket 23 , and the cross section of the supporting groove 231 is a V-shaped structure.

[0068] Specifically, the longitudinal section of the support bracket 23 is a V-shaped structure, so that after the film roll 100 is placed on the support bracket 23, the film roll 100 can be positioned by itself; and after the roll core 200 output by the material box 252 falls onto the support bracket 23, the support bracket 23 can be positioned by the V-shaped supporting groove 231 formed therein to ensure that the roll core 200 can be accurately placed on the air shaft 4.

[0069] In order to ensure that the winding core 200 is properly fitted onto the pneumatic shaft 4 during the process of fitting the winding core 200 onto the pneumatic shaft 4, the supporting groove 231 has two relatively inclined supporting surfaces, each of which has a through-hole. The supporting frame 23 is provided with slidable limiting pins 232, which are inserted into the corresponding through-holes. The limiting pins 232, which are arranged opposite to each other on the two supporting surfaces, are arranged at an angle to each other and, after extending out of the through-holes, form a clamping space between the supporting surfaces for clamping the winding core 200.

[0070] Specifically, after a new roll core 200 is placed onto the support bracket 23, it is positioned between the two support surfaces. A driving element, such as a pneumatic cylinder, then extends the limiting pins 232, clamping the roll core 200 against the support surface between the two cross-arranged limiting pins 232. As the roll core 200 is moved toward the pneumatic shaft 4 for loading via the sliding bracket 22, the limiting pins 232 press the roll core 200 against the support surface, preventing it from shifting due to contact with the pneumatic shaft 4. This ensures that the roll core 200 is securely mounted on the pneumatic shaft 4 and meets the requirements for proper assembly.

[0071] In actual use, there are various ways to unload the film core 200 from the support bracket 23. For example, the support bracket 23 can automatically unload the film roll 100 by self-rotation. Specifically, the support bracket 23 is rotatably mounted on the sliding frame 22, and a rotation drive component 26 is disposed between the support bracket 23 and the loading and unloading frame 21.

[0072] Specifically, during actual use, after the film roll 100 on the support frame 23 is detached from the air shaft 4, the sliding frame 22 has already driven the support frame 23 to leave the air shaft 4. At this time, the flipping drive component 26 is actuated to flip the support frame 23. After the flip, a supporting surface of the support frame 23 will extend downward at an angle, so that the film roll 100 relies on gravity to roll and fall from the support frame 23 along the supporting surface that extends downward at an angle, thereby realizing automatic unloading of the film roll 100.

[0073] The above-mentioned flipping method of the support frame 23 for unloading can meet the requirements of subsequent automatic film wrapping. In the case of manual intervention in unloading, the automatic loading and unloading equipment 2 also includes a transfer component 27, which includes a transfer seat 271, a transfer support shaft 272 and a rotation drive component 273. The transfer support shaft 272 is arranged horizontally and rotatably on the transfer seat 271, and the rotation drive component 273 is configured to drive the transfer support shaft 272 to rotate back and forth; wherein, the inflation and deflation component 24 is arranged at one end of the loading and unloading frame 21, the transfer component 27 is arranged at the other end of the loading and unloading frame 21, and the transfer seat 271 is arranged on the loading and unloading frame 21.

[0074] Specifically, for the film roll 100 on the support frame 23, during use, there are cases where the film roll 100 does not need to be wrapped and packaged due to quality issues found during inspection, or the film roll 100 needs to be manually packaged. At this time, during the separation process of the film roll 100 on the support frame 23 from the air shaft 4, the transfer support shaft 272 in the transfer assembly 27, which is distributed at different ends of the loading and unloading frame 21 from the inflation assembly 24, is in a basically coaxial state with the air shaft 4. After the air shaft 4 is deflated, the sliding frame 22 drives the support frame 23 to move, so that the film roll 100 is detached from the air shaft 4. At the same time, the transfer support shaft 272 will be inserted from the other side of the film roll 100 into the core 200 of the film roll 100, so that the film roll 100 is supported by the transfer support shaft 272.

[0075] After the film roll 100 is supported by the transfer support shaft 272, the transfer support shaft 272 is driven to rotate by the rotary drive component 273, so that the film roll 100 is rotated away from the support frame 23, thereby meeting the requirement of manually unloading the film roll 100 from the transfer support shaft 272. At the same time, the support frame 23 can be emptied in time, and a new roll core 200 can be put in from the material box 252 above for standby use.

[0076] Furthermore, in order to facilitate the installation of the transfer support shaft 272, a transfer bracket 274 is provided on the transfer seat 271, and a vertically arranged vertical shaft 275 is provided between the transfer bracket 274 and the transfer seat 271, the transfer support shaft 272 is provided on the vertical shaft 275, and the rotating drive component 273 is provided on the transfer bracket 274 and connected to the vertical shaft 275.

[0077] Specifically, the transfer bracket 274 set on the transfer seat 271 can meet the installation requirements of the transfer support shaft 272 and the rotating drive component 273. The vertical shaft 275 set on the transfer bracket 274 can meet the requirements of the horizontal arrangement of the transfer support shaft 272 and the horizontal rotation. The rotating drive component 273 can be a rotating cylinder or a motor and other components to drive the vertical shaft 275 to rotate and then drive the transfer support shaft 272 to rotate.

[0078] Furthermore, the loading and unloading rack 21 includes a base frame 211 and two upright frames 212. The base frame 211 is arranged horizontally, and the upright frames 212 are arranged vertically and fixed to the corresponding ends of the base frame 211. The sliding rack 22 is located between the two upright frames 212 and is slidably arranged on the base frame 211; a lifting drive component 213 is provided on the upright frame 212; the inflation and deflation base 241 is slidably arranged on the upright frame 212 and is connected to the corresponding lifting drive component 213; the transfer seat 271 is slidably arranged on the upright frame 212 and is connected to the corresponding lifting drive component 213.

[0079] Specifically, the inflation and deflation assembly 24 and the transfer assembly 27 can both move up and down on the corresponding stand 212. Since the height position of the support frame 23 is unchanged, when the film roll 100 is placed on the support frame 23, the larger diameter of the film roll 100 causes the height of the air-inflating shaft 4 and the core 200 to be higher. At this time, the inflation and deflation assembly 24 needs to be lifted accordingly so that the end of the air-inflating shaft 4 can be located between the two clamping components. At the same time, when the film roll 100 needs to be transferred to the transfer support shaft 272, the transfer assembly 27 is lifted to a corresponding height so that the transfer support shaft 272 matches the height of the core 200 in the film roll 100.

[0080] At the same time, when placing a new film core 200 on the support bracket 23 to fit over the air shaft 4 held by the inflation / deflation assembly 24, since the height of the film core 200 on the support bracket 23 is relatively low, the overall height of the inflation / deflation assembly 24 needs to be lowered so that the height of the air shaft 4 matches that of the film core 200 on the support bracket 23. This allows the air shaft 4 to automatically unload the film roll 100 and automatically install a new film core 200 onto the air shaft 4.

[0081] Furthermore, for the material box 252 , which stores a plurality of winding cores 200 , in order to meet the requirement of outputting one winding core 200 through the discharge port 2521 at a time, the following structural improvements are made to the material box 252 .

[0082] The material box 252 includes a storage bin 2522 and a conveying channel 2523. The bottom of the storage bin 2522 is provided with a connecting port (not marked). The conveying channel 2523 is arranged vertically and is arranged on the connecting port. The bottom of the conveying channel 2523 forms the discharge port 2521. The side wall of the conveying channel 2523 is provided with a first plug hole and a second plug hole arranged up and down. The side wall of the conveying channel 2523 is also provided with a first plug plate 2524, a second plug plate 2525 and a plug plate driving component 2526 that can slide. The first plug plate 2524 is inserted into the first plug hole, and the second plug plate 2525 is inserted into the second plug hole.

[0083] The second plug-in plate 2525 is located below the first plug-in plate 2524 , and the second plug-in plate 2525 is configured to open and close the discharge port 2521 ; and the first plug-in plate 2524 and the second plug-in plate 2525 form a temporary storage space in the conveying channel 2523 for accommodating a single winding core 200 .

[0084] Specifically, the storage bin 2522 has a large capacity and width to accommodate a plurality of winding cores 200, while the width of the conveying channel 2523 at the bottom of the storage bin 2522 is smaller than the width of the storage bin 2522. In particular, the width of the conveying channel 2523 at the discharge port 2521 needs to be larger than the diameter of a single winding core 200 and smaller than the diameters of two winding cores 200. As for the conveying channel 2523, a first plug plate 2524 and a second plug plate 2525 are arranged in an upper and lower manner near the discharge port 2521. The second plug plate 2525 is used to control the switch of the discharge port 2521, and the area between the first plug plate 2524 and the second plug plate 2525 in the conveying channel 2523 forms a space for accommodating a single winding core 200. In this way, the first plug plate 2524 and the second plug plate 2525 are driven by the plug plate driving components 2526 corresponding to the first plug plate 2524 and the second plug plate 2525, so that the first plug plate 2524 and the second plug plate 2525 slide alternately to achieve a single output of a winding core 200.

[0085] Furthermore, in order to guide the winding core 200 in the storage bin 2522 to smoothly enter the conveying channel 2523, an inclined guide portion 2527 is formed at the bottom of the storage bin 2522, and the inclined guide portion 2527 extends upward along the connecting port.

[0086] Specifically, the winding cores 200 at the bottom of the storage bin 2522 can be neatly arranged and slid into the conveying channel 2523 via the inclined guide portion 2527 to ensure smooth output of the winding cores 200.

[0087] Furthermore, since the core 200 is longer in the length direction, the core 200 stored in the storage bin 2522 is prone to cross at the connection port, which makes the core 200 unable to enter the conveying channel 2523. For this reason, the supply assembly 25 also includes a toggle module 253, and the toggle module 253 includes a toggle rod 2531, two connecting rods 2532 and a toggle drive component 2533. The toggle rod 2531 is connected between the two connecting rods 2532; the connecting rod 2532 and the toggle rod 2531 are located in the storage bin 2522, and the upper end of the connecting rod 2532 is hinged on the inclined guide part 2527. The toggle rod 2531 is close to the connection port and extends along the length direction of the connection port. The toggle drive component 2533 is configured to drive the connecting rod 2532 to rotate.

[0088] Specifically, when the winding cores 200 near the connection port of the storage bin 2522 are blocked due to cross interference, the toggle module 253 can be used to toggle the winding cores 200 at the bottom of the storage bin 2522. The toggle drive component 2533 drives the toggle rod 2531 to move up and down at the connection port through the connecting rod 2532 to toggle and sort out the winding cores 200 at the connection port. Since the toggle rod 2531 extends along the length of the connection port, the toggle action of the toggle rod 2531 allows the crossed winding cores 200 to be sorted out smoothly, thereby solving the problem of cross-blocking of the winding cores 200 and ensuring smooth output of the winding cores 200.

[0089] Preferably, a baffle 2528 is further provided at the connection port. The baffle 2528 is located in the storage bin 2522 and is provided on the inclined guide portion 2527. The baffle 2528 is located between the shifting rod 2531 and the connection port.

[0090] Specifically, when the lever 2531 moves the winding core 200 , the baffle 2528 on one side of the lever 2531 can better correct the skewed winding core 200 to the correct posture.

[0091] The lower end of the baffle 2528 is disposed on the inclined guide portion 2527, and a positioning surface is formed on the upper end of the baffle 2528. The positioning surface is arranged vertically and parallel to the inner wall of the conveying channel 2523. Specifically, when the lever 2531 is moved, the winding core 200 located between the lever 2531 and the baffle 2528 is corrected in posture. After passing the baffle 2528 along the top positioning surface, the baffle 2528 can further guide the winding core 200 to slide into the connection port below in the correct posture.

[0092] Furthermore, in order to meet the requirements for winding films of different specifications and sizes, the storage bin 2522 also needs to meet the supply requirements of winding cores 200 of different lengths. In order to improve versatility, the storage bin 2522 is also provided with an adjustment plate 254. The adjustment plate 254 is arranged vertically and is horizontally slidable in the storage bin 2522. The outer contour of the adjustment plate 254 matches the contour of the cross section of the storage bin 2522 perpendicular to the length direction. The bottom of the adjustment plate 254 is also provided with an extension plate 255. The extension plate 255 extends into the conveying channel 2523.

[0093] Specifically, the adjustment plate 254 is vertically arranged in the storage bin 2522 to adjust the length of the space for storing the roll paper in the storage bin 2522. To meet the supply requirements of the roll cores 200 of different lengths, the adjustment plate 254 can be adjusted horizontally to adjust the effective container length of the storage bin 2522. For example, the side wall of the storage bin 2522 is provided with horizontally arranged strip holes, and the adjustment plate 254 is provided with threaded holes, through which bolts pass and are threadedly connected.

[0094] Based on the above technical solution, optionally, in order to meet the requirements of the air shaft 4 for automatically unloading the film roll 100 and automatically loading the roll core 200 through the automatic loading and unloading equipment 2, the air shaft 4 is also structurally improved. Figure 15-17 Provide explanation.

[0095] The inflatable shaft 4 includes an inflation and deflation shaft 41 and an expansion component, and the expansion component is arranged on the inflation and deflation shaft 41; the end face of one end of the inflation and deflation shaft 41 is provided with an inflation and deflation hole, and an air nozzle 42 is provided in the inflation and deflation hole. A positioning sleeve 43 is also provided on the inflation and deflation shaft 41, and the positioning sleeve 43 is arranged close to the air nozzle 42.

[0096] Specifically, an air cavity is formed within the inflation / deflation shaft 41, into which air is inflated through the inflation / deflation holes, causing the expansion member to expand outward. Simultaneously, the inflation / deflation holes allow air within the cavity to escape, causing the expansion member to retract. The specific method for expanding and contracting the expansion member on the inflation / deflation shaft 41 can be referenced to the structural configuration of a conventional inflation shaft 4 and is not limited here.

[0097] By configuring an air charging and discharging hole at one end of the air charging and discharging shaft 41, both the requirement of inflation and the requirement of deflation can be met. Then, the air charging and discharging part 242 of the air charging and discharging assembly 24 can be used to inflate and deflate the device 2 in conjunction with the automatic loading and unloading device 2 during use.

[0098] The air nozzle 42 is press-open, similar to conventional press-open air nozzles. Thus, during inflation and deflation, the inflation / deflation component 242 abuts against the air nozzle 42 to open the air nozzle 42 and connect it to the first vent 2421. Inflation and deflation are then performed as needed.

[0099] At the same time, since the inflation shaft 4 needs to automatically put on the new core 200, in order to ensure the accuracy of the installation of the core 200, a positioning sleeve 43 is provided at one end of the inflation and deflation shaft 41. The positioning sleeve 43 can position the core 200 on the inflation and deflation shaft 41.

[0100] As the new winding core 200 is moved onto the inflation / deflation shaft 41 by the support bracket 23, the winding core 200 abuts against the positioning sleeve 43, securing the winding core 200 in place. The positioning sleeve 43 ensures that the winding core 200 meets the required assembly accuracy during the automatic insertion process, ensuring that the winding core 200 can be automatically assembled into place.

[0101] Furthermore, an end surface of one end of the inflation / deflation shaft 41 is provided with an inserting groove 44 , and an inflation / deflation hole is opened in the inserting groove 44 .

[0102] Specifically, by setting a plug-in groove 44 at the end of the air inflation shaft 4, the plug-in groove 44 can, on the one hand, meet the installation requirements of the air nozzle 42 so that it can be built into the plug-in groove 44 to avoid being bumped to improve the reliability of use. On the other hand, the plug-in groove 44 can guide the inflation and deflation component 242 to be accurately inserted into the interior to open the air nozzle 42.

[0103] In order to improve the sealing reliability of the connection, the free end of the inflation and deflation component 242 is a conical structure; when the air shaft 4 is inflated and deflated, the free end of the inflation and deflation component 242 is sealed and inserted into the plug-in groove 44.

[0104] Furthermore, during the automatic loading and unloading process of the inflatable shaft 4, since the inflatable shaft 4 needs to be clamped by the inflation and deflation assembly 24 of the automatic loading and unloading equipment 2 and one end is suspended in the air, in order to improve the clamping reliability of the inflatable shaft 4, the outer surface of the inflation and deflation shaft 41 is also provided with an annular positioning groove 45, and the annular positioning groove 45 is arranged on the outside of the positioning sleeve 43.

[0105] Specifically, after the pneumatic shaft 4 is placed on the support bracket 23 of the automatic loading and unloading device 2, the unloading clamp 246 of the inflation / deflation assembly 24 engages in the annular positioning groove 45. Simultaneously, the free end of the inflation / deflation shaft 41 is clamped and secured by the clamping member. Thus, after the support bracket 23 of the automatic loading and unloading device 2 drives the film frame off the pneumatic shaft 4, one end of the pneumatic shaft 4 is effectively supported by the clamping member and the unloading clamp 246, thus meeting the requirements for posture stability when the other end of the pneumatic shaft 4 is suspended in the air.

[0106] In another embodiment of the present application, for the film roll 100 unloaded from the automatic loading and unloading device 2, in order to meet the requirements of the automation design of the subsequent film wrapping and packaging process, the automatic film winding and loading and unloading system also includes a packaging and transporting device 3, which can receive the film roll 100 unloaded from the automatic loading and unloading device 2 and automatically wrap and package the film roll 100. Figure 12-14 , the specific structure of the packaging and transfer equipment 3 is explained.

[0107] The packaging and transfer equipment 3 includes a packaging frame 31, a carrying frame 32 and a film clamping assembly 33. The top of the packaging frame 31 is provided with an axle seat 34, and the axle seat 34 is configured to carry a packaging reel 35 wrapped with packaging film 300. The carrying frame 32 is rotatably provided on the packaging frame 31, and at least one rotatable support roller 36 is provided on the carrying frame 32, and the support roller 36 extends along the axis direction of the rotating shaft of the carrying frame 32; the film clamping assembly 33 includes a film clamping part 331 and a film clamping lifting seat 332, and the film clamping lifting seat 332 is slidably provided on the packaging frame 31 and is located above the supporting frame 23. The film clamping part 331 is provided on the film clamping lifting seat 332, and the film clamping part 331 is configured to clamp the packaging film 300 output by the packaging reel 35;

[0108] The packaging and transfer equipment 3 is arranged on one side of the automatic loading and unloading equipment 2 , and the carrier 32 is configured to receive the film roll 100 output from the supporting frame 23 .

[0109] Specifically, during actual use, after the film roll 100 is detached from the air shaft 4 , the support bracket 23 follows the sliding bracket 22 to move to the carrier 32 . At this time, the support bracket 23 flips over to allow the film roll 100 to roll onto the carrier 32 .

[0110] After the film roll 100 rolls onto the carrier 32 , the carrier 32 can be driven by the cylinder to rotate from an inclined state to a horizontal state to stably carry the film roll 100 .

[0111] The film clamping lift seat 332 can move downward along the packaging frame 31 under the driving action of the lifting cylinder 1423, and the film clamping component 331 on the film clamping lift seat 332 will clamp the packaging film 300 on the packaging reel 35 and move it downward and abut against the surface of the film roll 100; then, the supporting roller 36 rotates under the driving action of the packaging motor 37 to drive the film roll 100 on the supporting frame 32 to rotate, thereby making the packaging film 300 wound around the surface of the film roll 100 to complete the automatic winding of the packaging film 300 on the surface of the film roll 100.

[0112] The film roll 100 is driven to rotate by the support roller 36, and the film clamping assembly 33 is used to clamp the packaging film 300 against the surface of the film roll 100, so that the film roll 100 can automatically wrap the packaging film 300 around its own surface while rotating, so as to realize automatic film wrapping and packaging. In this way, the film roll 100 can be automatically wrapped and packaged after being unwound. The film roll 100 is supported and driven to rotate by the support roller 36 at the bottom, and there is no need to manually lift and transport the film roll 100 to the drive shaft, which reduces the labor intensity of workers.

[0113] Furthermore, the film clamping component 331 includes a clamping bracket 3311, a first roller 3312, a second roller 3313 and a clamping drive component 3314, the first roller 3312 is rotatably set on the film clamping lifting seat 332, the second roller 3313 is rotatably set on the clamping bracket 3311, the clamping bracket 3311 is slidably set on the film clamping lifting seat 332, and the clamping drive component 3314 is configured to drive the clamping bracket 3311 to slide close to or away from the first roller 3312.

[0114] Specifically, in order to effectively clamp the packaging film 300 and meet the requirement that the packaging film 300 is automatically wound onto the film roll 100 during the rotation of the film roll 100, the first roller 3312 and the second roller 3313 cooperate with each other to clamp the packaging film 300.

[0115] The film clamping component 331 is mounted on the film clamping lift 332 to facilitate conveying the packaging film 300 to the surface of the film roll 100 below. At this point, the packaging film 300 is pressed between the first roller 3312 and the film roll 100, with the first roller 3312 pressing the head of the packaging film 300 against the film roll 100. As the film roll 100 is rotated by the support roller 36 for packaging, the clamping drive component 3314 (such as a cylinder or electric push rod) drives the clamping bracket 3311 away from the first roller 3312, creating a gap between the second roller 3313 and the first roller 3312. This allows the packaging film 300 to be continuously conveyed to the film roll 100 through the gap between the first roller 3312 and the second roller 3313. The film clamping lift 332 can be driven to slide up and down by the film clamping lift cylinder 3331423.

[0116] In the process of continuously wrapping the packaging film 300 around the surface of the film roll 100 , the first roller 3312 can guide and press the packaging film 300 to reliably wrap around the surface of the film roll 100 , thereby improving the quality of packaging.

[0117] Furthermore, after wrapping a sufficient number of wrapping film 300 around the film roll 100, the wrapping film 300 needs to be cut. To this end, the packaging and transporting device 3 further includes a cutting assembly 38, which includes a cutting bracket 381, a cutter 382, ​​and a cutting drive component 383. The cutting bracket 381 is arranged transversely and disposed on the packaging frame 31, the cutter 382 is slidably disposed on the cutting bracket 381, and the cutting drive component 383 is configured to drive the cutter 382 to slide on the cutting bracket 381.

[0118] Specifically, after wrapping the packaging film 300 around the film roll 100, the film clamping lift 332 drives the film clamping assembly 33 to move above the cutting assembly 38. At this point, the packaging film 300 is tensioned and positioned between the packaging reel 35 and the film roll 100, and between the first roller 3312 and the second roller 3313. The clamping drive 3314 then drives the clamping bracket 3311 to move, clamping the packaging film 300 between the first roller 3312 and the second roller 3313. The cutting drive 383 then drives the cutter 382 to cut the packaging film 300 between the film clamping assembly 331 and the film roll 100. After the packaging film 300 is cut, the top of the packaging film 300 is exposed below the first roller 3312 and the second roller 3313, allowing it to be effectively wound onto a new film roll 100 during the next packaging process.

[0119] Furthermore, to prevent the packaging film 300 from accidentally contacting the cutter 382 and being cut during the wrapping process, the cutting bracket 381 is provided with an operation window, and the operation window is provided with an upside-down cover plate 384. The cutter 382 is arranged opposite the operation window. The cutting drive component 383 is configured to drive the cutter 382 to extend from the operation window and push open the cover plate 384.

[0120] Specifically, when not in use, the cutter 382 retracts to one side of the operation window and is covered by the cover 384 , so as to prevent the packaging film 300 from contacting the cutter 382 through the cover 384 .

[0121] Furthermore, in order to improve the rotation stability of the film roll 100, the carrier frame 32 is provided with two support rollers 36 arranged side by side, and the packaging frame 31 is provided with a synchronous drive component 14124, which is configured to drive the two support rollers 36 to rotate synchronously.

[0122] Specifically, the power of the synchronous driving component 14124 comes from the packaging motor 37, and can drive the two supporting rollers 36 arranged side by side to rotate synchronously through a belt or chain, so that the film roll 100 on the two supporting rollers 36 rotates smoothly.

[0123] The first roller 3312 may be arranged in the middle portion above the two support rollers 36 , so that the first roller 3312 can press the packaging film 300 onto the top of the film roll 100 .

[0124] In addition, after the film roll 100 is wrapped and packaged, the support roller 36 slows down and stops. In order to prevent the packaging reel 35 from continuing to rotate due to inertia, a brake 39 can also be provided on the packaging frame 31. The brake 39 is arranged on one side of the shaft seat 34 and is configured to brake the packaging reel 35 to match the rotation speed of the support roller 36.

[0125] Based on the above technical solution, a specific control method for the automatic film winding and loading and unloading system during use includes a control process.

[0126] The winder 1 drives the air-expansion shaft 4 to rotate the winding core 200 through the winding shaft drive module 13 to complete the film winding onto the winding core 200 to form a film roll 100. The air-expansion shaft 4 and the film roll 100 are placed on the support frame 23 of the automatic loading and unloading device 2.

[0127] The inflation and deflation component 24 of the automatic loading and unloading equipment 2 clamps the end of the air shaft 4 and connects the inflation and deflation component 242 to the inflation and deflation holes of the air shaft 4 to deflate the air shaft 4. The sliding frame 22 slides in the direction away from the inflation and deflation component 24 so that the support frame 23 drives the film roll 100 to separate from the air shaft 4. The support frame 23 flips over so that the film roll 100 rolls onto the supporting frame 32 of the packaging and transfer equipment 3; then, the unloading port 2521 of the material box 252 is opened so that the roll core 200 falls onto the support frame 23, the sliding frame 22 moves and resets so that the roll core 200 is sleeved on the air shaft 4, and the inflation and deflation component 242 inflates the air shaft 4 again. Finally, the air shaft 4 with the roll core 200 is hoisted and recovered to the winding machine 1 for standby use by the hoisting fixture;

[0128] The film clamping component 331 of the packaging and transfer device 3 clamps the packaging film 300 and moves downward so that the packaging film 300 is attached to the film roll 100. The supporting roller 36 rotates to drive the film roll 100 to rotate so that the packaging film 300 is wound around the film roll 100 to complete the packaging.

[0129] Specifically, after the winder 1 completes the automatic winding operation of the film, the winding core 200 on the pneumatic shaft 4 is wound with the film to form a film roll 100. The pneumatic shaft 4 can be lifted and removed from the winder 1 through the lifting module 14 and placed on the support bracket 23 in the automatic loading and unloading equipment 2 on one side.

[0130] At the same time, the corresponding end of the inflatable shaft 4 will be located between the two clamping parts of the inflation and deflation assembly 24, so that the end of the inflatable shaft 4 can be clamped and positioned by the two clamping parts. Then, the inflation and deflation component 242 moves toward the end of the inflatable shaft 4 to press the air nozzle 42 at the end of the inflatable shaft 4, and the inflatable shaft 4 is deflated by the inflation and deflation component 242. After the inflatable shaft 4 completes the deflation operation, the sliding frame 22 can drive the support frame 23 to move so that the film roll 100 on the support frame 23 is detached from the inflatable shaft 4. The sliding frame 22 drives the film roll 100 to move to one side of the packaging and transportation equipment 3, and the support frame 23 flips so that the film roll 100 rolls onto the carrier frame 32 of the packaging and transportation equipment 3 to complete the automatic unloading of the film roll 100.

[0131] After receiving the film roll 100, the carrier frame 32 flips to a horizontal position so that the film roll 100 is supported by two support rollers 36. The film clamping assembly 33 drives the packaging film 300 downward and presses the packaging film 300 onto the film roll 100 via the first roller 3312. The second roller 3313 moves away from the first roller 3312 and activates the support rollers 36 to rotate the film roll 100, so that the packaging film 300 is wound around the film roll 100. After the packaging film 300 has been wrapped around the surface of the film roll 100 for a set number of turns, the film clamping assembly 33 rises and the second roller 3313 moves closer to the first roller 3312 to clamp the packaging film 300. The packaging film 300 is then cut between the film clamping assembly 33 and the film roll 100 by the cutting assembly 38, completing the automatic packaging of the film roll 100.

[0132] During the control process, after the film roll 100 on the support bracket 23 is unloaded, the supply component 25 puts the new core 200 onto the support bracket 23, and the limiting ejector 232 on the support bracket 23 extends and clamps the core 200 on the support bracket 23; then, the sliding frame 22 moves toward the inflation and deflation component 24, and after the core 200 is completely covered on the air shaft 4, the inflation and deflation component 24 inflates the air shaft 4 to complete the automatic covering of the air shaft 4 with the core 200.
