Description

Technical Field

[0001] The present invention relates to the technical field of paper can production equipment, in particular to a paper can pattern positioning and loading machine. Background Art

[0002] The paper can loading machine is a paper can loading and bottom sealing device, which is used to install discs on the bottom of paper cans. Before loading, trademarks and other patterns will be printed on the discs and paper cans. When loading, the pattern on the disc is often required to correspond to the pattern position of the paper can. The existing paper can loading machine cannot position the discs when loading, resulting in random orientation of the pattern on the disc. The appearance of the finished paper can after loading is inconsistent and cannot meet production needs. Secondly, the existing loading equipment puts the discs vertically into the paper cans when loading. The friction between the discs and the paper cans is large, and the insertion is not smooth. Moreover, the paper can is placed on the loading platform and the discs are put vertically, which will form a large pressure on the bottom of the paper can. In severe cases, it will cause the paper can to deform, affecting the quality of the finished product. There is room for improvement. Summary of the Invention

The controller is electrically connected to the film supply device 2, the wafer pattern positioning and feeding device 3, the paper can pattern positioning device 4, the tilting delivery device 5 and the film pressing device 6. The controller controls the actions of each process of the film loading machine, and the degree of automation is high.

[0064] In this embodiment, the film feed device 2 is mounted on one side of the frame 1 and provides wafers to the wafer pattern positioning and feeding device 3. The film feed device 2 includes a fixed base 21 mounted on the frame 1. A station switching cylinder 221 is slidably mounted on the fixed base 21. The station switching cylinder 221 is drivingly connected to a mounting frame 222, which is provided with a switching chute 223. A switching slider 224 is slidably mounted within the switching chute 223. The switching slider 224 is fixed to the fixed base 21. During use, the station switching cylinder 221 drives the mounting frame 222 to slide along the switching chute 223, thereby switching the film feed station.

[0065] In this embodiment, a film supply platform 23 is installed on the work station switching assembly 22. Specifically, the film supply platform 23 is installed on the top of the fixed frame. The film supply platform 23 is provided with a first film supply bin 241 and a second film supply bin 242 along the axial direction of the work station switching cylinder 221. The first film supply bin 241 and the second film supply bin 242 are both surrounded by a number of limiting rods 231. The distance between the limiting rods 231 is adjustable. Specifically, adjustment holes 232 are provided on the film supply platform 23. The number of the adjustment holes 232 is ten and arranged radially. In some other embodiments, the number of the adjustment holes 232 is set as needed. The bottom of the limiting rod 231 is provided with an adjustment block 233, and the adjustment block 233 is fixed to the adjustment hole 232 by a pin or a bolt. During operation, the wafers used for processing are stacked in the first film supply bin 241 and the second film supply bin 242, and the limiting rod 231 is installed on different adjustment holes 232, so as to adjust the size of the first film supply bin 241 and the second film supply bin 242, so that the size of the first film supply bin 241 and the second film supply bin 242 are adapted to the diameter of the wafers used for processing.

[0066] In this embodiment, the bottom of each of the first film supply bin 241 and the second film supply bin 242 is provided with a sheet height adjustment assembly 25. The sheet height adjustment assembly includes a hollow shaft stepper motor 251 mounted at the bottom of the film supply platform 23. The hollow shaft stepper motor 251 is drivingly connected to a hollow sleeve 252, which is connected to a screw rod 253 via an internal thread 254. A sheet support plate 255 is fixed to the top of the screw rod 253. The sheet support plate 255 is slidably mounted on the limiting rod 231. The sheet support plate 255 is provided with a first strip hole 2551, and the sheet support plate 255 is slidably mounted on the limiting rod 231 through the first strip hole 2551. During use, the wafer is placed on the supporting plate 255, and the screw 253 is driven up and down by the hollow shaft stepping motor 251, thereby driving the supporting plate 255 installed on the top of the screw 253 to move up and down, so as to adjust the height of the wafer. A first strip hole 2551 is provided on the supporting plate 255 to facilitate the adjustment of the size of the first film supply bin 241 and the second film supply bin 242.

[0067] In this embodiment, the frame 1 is provided with a height sensor 26 for detecting the height of the material in the first film supply bin 241 or the second film supply bin 242. The model of the height sensor 26 in this embodiment is E32-DC200. In some other embodiments, the model of the height sensor 26 is selected according to needs. The height sensor 26 is electrically connected to the controller, and the controller is electrically connected to the height adjustment component. When working, the height sensor 26 monitors the height of the wafer in the first film supply bin 241 or the second film supply bin 242, and transmits the detected electrical signal to the controller. The controller controls the height adjustment component to adjust the height of the wafer in real time.

[0068] In this embodiment, the wafer pattern positioning and feeding device 3 is installed on the side of the frame 1 close to the film feeding device 2, and is used to position the wafer; it includes a film feeding panel 31, a driving cylinder 321, a film taking assembly 33, a first film support rack 34, a second film support rack 35, a rotating suction cup assembly 36 and a wafer alignment sensor 37.

[0069] In this embodiment, the driving cylinder 321 is disposed on one side of the film feeding panel 31. The output end of the driving cylinder 321 is connected to a film feeding slider 322. A slide rail 323 is provided on the side of the film feeding panel 31. The film feeding slider 322 is slidably mounted on the slide rail 323. The film taking assembly 33 is mounted on the film feeding slider 322. During operation, the driving cylinder 321 drives the film feeding slider 322 to slide back and forth along the slide rail 323, thereby driving the film taking assembly 33 to slide back and forth.

[0070] The first and second film picking cylinders 333 are respectively mounted on the front and rear ends of the mounting arm 331, and the first and second film picking cylinders 332 and 333 are respectively mounted on the front and rear ends of the mounting arm 331. The output end of the first film picking cylinder 332 is mounted with a first film picking suction cup 334, and the output end of the second film picking cylinder 333 is mounted with a second film picking suction cup 335. In this embodiment, the first and second film picking suction cups 334 and 335 are both pneumatic suction cups. The principle is the existing technology and will not be repeated here. The first and second film picking suction cups 334 and 335 are at the same height and move up and down synchronously. In some other embodiments, the first and second film picking suction cups 334 and 335 can be set as needed. During operation, the driving cylinder 321 extends, driving the mounting arm 331 to the film taking position. At this time, the first film taking cylinder 332 is located above the first film supply bin 241 of the film supply device 2, and the second film taking cylinder 333 is located above the first film supporting rack 34. Then the first film taking cylinder 332 and the second film taking cylinder 333 extend, driving the first film taking suction cup 334 and the second film taking suction cup 335 to move downward. The first film taking suction cup 334 absorbs the wafer placed on the first film supply bin 241, and the second film taking suction cup 335 absorbs the wafer placed on the first film supporting rack 34. Then the first film taking cylinder 332 and the second film taking cylinder 333 extend, driving the first film taking suction cup 334 and the second film taking suction cup 335 to move downward. 332 and the second film picking cylinder 333 contract, the driving cylinder 321 contracts, and the mounting arm 331 moves accordingly. When the first film picking cylinder 332 moves above the first film supporting rack 34, the driving cylinder 321 stops working. Then the first film picking cylinder 332 and the second film picking cylinder 333 extend, driving the first film picking suction cup 334 and the second film picking suction cup 335 to move downward. The first film picking suction cup 334 places the sucked wafer on the first film supporting rack 34, and the second film picking suction cup 335 places the sucked wafer on the second film supporting rack 35 for subsequent use by the tilting delivery device 5.

[0071] In this embodiment, the first sheet support 34 and the second sheet support 35 are installed on the sheet feeding panel 31 along the direction of extension and contraction of the driving cylinder 321, and are used to place paper can round sheets. The first sheet support is located below the sheet taking assembly 33. The first sheet support 34 is surrounded by a plurality of first limiting columns 341. A first strip mounting hole 342 is provided on the sheet feeding panel 31. The first limiting column 341 is installed on the first strip mounting hole 342 by a bolt. The first strip mounting hole 342 is provided to facilitate the adjustment of the distance between the first limiting columns 341, thereby facilitating the adjustment of the size of the first sheet support 34 to accommodate round sheets of different sizes. A plane bearing 343 is provided on the first limiting column 341. A first strip-shaped mounting hole 342 is provided, and the first limiting column 341 is installed at different positions of the first strip-shaped mounting hole 342 to adjust the size of the first support frame 34 to accommodate wafers of different sizes. When in use, the wafer is placed on the plane bearing 343, and the wafer rotates with the rotating suction cup assembly 36 to achieve centering. The plane bearing 343 can reduce the friction between the wafer and the first limiting column 341, thereby reducing the alignment error.

[0072] In this embodiment, the second wafer support 35 is formed by a plurality of second limiting posts 351. The wafer transfer panel 31 is provided with second strip-shaped mounting holes 352, and the second limiting posts 351 are bolted to the second strip-shaped mounting holes 352. The second strip-shaped mounting holes 352 facilitate adjustment of the size of the second wafer support 35 to accommodate wafers of different sizes, which are placed between the second limiting posts 351.

[0073] In this embodiment, the rotating suction cup assembly 36 includes a suction cup body 361, a driven wheel 362, a driving wheel 363 and a synchronous wheel motor 364. The synchronous wheel motor 364 is mounted on the film feeding panel 31. The driving wheel 363 is transmission-connected to the synchronous wheel motor 364. The driven wheel 362 is transmission-connected to the driving wheel 363 through a transmission belt. A hollow shaft 365 is coaxially fixed to the driven wheel 362. The suction cup body 361 is mounted on the top of the hollow shaft 365. The suction cup body 361 is located at the center of the first film support frame 34. An air suction hole is provided on the adsorption surface of the suction cup body 361. The air suction hole is connected to the air suction pipe 367 through the hollow shaft 365. The suction cup body 361 is made of PEEK material. The surface of PEEK material is smooth and will not stick to the wafer. The bottom of the hollow shaft 365 is threadedly connected to a rotating interface 366, and the rotating interface 366 is rotatably connected to the air suction pipe 367 through a bearing. During use, air is taken in by the suction pipe 367, and the suction hole is connected to the suction pipe 367 through the hollow shaft 365, so that the disc is adsorbed on the suction cup body 361, and the synchronous wheel motor 364 drives the driving wheel 363 and the driven wheel 362 to rotate synchronously, driving the hollow shaft 365 to rotate, and then driving the disc to rotate with the suction cup body 361.

[0074] In this embodiment, the wafer alignment sensor 37 is installed on the sheet feeding panel 31 and is used to detect the position of the wafer. The model of the wafer alignment sensor 37 in this embodiment is E32-DC200. In some other embodiments, the model of the wafer alignment sensor 37 is selected according to needs. The wafer alignment sensor 37 is electrically connected to the controller, and the controller is electrically connected to the synchronous wheel motor 364; the wafer alignment sensor 37 is installed at the bottom of the sheet feeding panel 31, and a light-transmitting groove 371 is provided on the sheet feeding panel 31, and the light-transmitting groove 371 is located between the wafer alignment sensor 37 and the first support rack 34. The wafer is printed with an identification mark for the wafer alignment sensor 37 to identify. When the wafer on the first wafer support 34 rotates to the appropriate position with the suction cup body 361, the wafer alignment sensor 37 identifies the identification mark on the wafer and transmits the identified electrical signal to the controller. The controller controls the synchronous wheel motor 364 to stop working, so that the suction cup body 361 stops rotating, the wafer taking device works, and the wafer is placed on the second wafer support 35 for subsequent use by the tilting delivery device 5.

[0075] In this embodiment, the paper can pattern positioning device 4 is installed on the frame 1 near the round wafer pattern positioning and feeding device 3, and is used to position the paper can; it includes a rotating component 45, a conveying component and a paper can alignment sensor 46, and the conveying component includes a first conveying component 41, an arc conveying component 43, an arc block 47 and a second conveying component 42.

[0076] In this embodiment, the first conveying assembly 41 and the second conveying assembly 42 are respectively arranged on both sides of the frame 1. The first conveying assembly 41 and the second conveying assembly 42 in this embodiment are conveyor belts. The paper cans to be processed are placed on the first conveying assembly 41. During operation, the paper cans pass through the first conveying assembly 41, the arc conveying assembly 43 and the second conveying assembly 42 in sequence. Finally, the finished paper cans are conveyed out by the second conveying assembly 42. The arc conveying assembly 43 is installed on the frame 1. The arc conveying assembly 43 is located between the first conveying assembly 41 and the second conveying assembly 42. A mounting plate 44 is provided on the frame 1. The mounting plate 44 is located between the arc conveying assembly 43 and the second conveying assembly 42. The bottom of the part 43, the arc conveying assembly 43 includes a conveying motor installed on the frame 1, the conveying motor is connected to the main shaft 431, and the main shaft 431 is detachably connected to a turntable 433 through a flange part 432. In this embodiment, there are two turntables 433. The detachable installation method of the turntable 433 makes it easy to adjust its height to accommodate paper cans of different heights. The edge circumference array of the turntable 433 has multiple semicircular notches 4331, and an arc stopper 47 is provided on the frame 1. The arc stopper 47 is located on one side of the turntable 433, and the two ends of the arc stopper 47 are respectively connected to the first conveying assembly 41 and the second conveying assembly 42.

[0077] The arc-shaped baffle 47 includes an arc-shaped baffle 471, a splint 472, a telescopic rod 473 and a base 474. The base 474 is installed on the frame 1. The arc-shaped baffle 471 is located on one side of the turntable 433. The arc-shaped baffle 471 is fixed to the inner side of the splint 472 by bolts. A third strip hole 475 is provided on the outer side of the splint 472. A telescopic rod 473 is vertically installed on the base 474. The splint 472 is installed on the telescopic rod 473 through the third strip hole 475. The structure of the telescopic rod 473 is the existing technology and will not be repeated here. The splint 472 is installed on the telescopic rod 473 and can be adjusted up and down with the telescopic rod 473, so that the height of the arc-shaped baffle 471 can be adjusted according to the height of the paper can. The splint 472 is installed on the telescopic rod 473 through the third strip hole 475, so that the front and rear positions of the arc-shaped baffle 471 can be adjusted according to the diameter of the paper can. During operation, the first conveying component 41 conveys the paper can to be processed to the mounting plate 44. At this time, the paper can is clamped between the semicircular notch 4331 and the arc-shaped baffle 471. The conveying motor works to drive the turntable 433 to rotate, and then drives the paper can to rotate with the turntable 433. When it reaches the second conveying component 42, due to the lack of restriction of the arc-shaped baffle 471, the paper can is conveyed out by the second conveying component 42.

[0080] In this embodiment, the inclined delivery device 5 is installed above the paper can pattern positioning device, and is used to tilt the wafers into the paper can; the inclined delivery device 5 includes a transverse rodless cylinder 51, a lifting rodless cylinder 52 and a delivery assembly 53, the transverse rodless cylinder 51 is installed on the frame 1, the lifting rodless cylinder 52 is installed on the transverse rodless cylinder 51 and moves horizontally under the drive of the transverse rodless cylinder 51, and the side of the lifting rodless cylinder 52 is installed with a guide plate 54, the guide plate A guide groove 541 is provided on the plate 54, and the guide groove 541 includes an inclined section 5411 and a vertical section 5412 that are connected to each other. The inclined section 5411 is located at the upper part of the vertical section 5412. The lifting rodless cylinder 52 is transmission-connected to the mounting block 55, and the mounting block 55 is rotationally connected to the connecting rod 57 through the rotating rod 56. A guide block is provided on the inner side of the connecting rod 57, and the guide block is slidably connected in the guide groove 541. The delivery assembly 53 is installed on the connecting rod 57.

[0081] In this embodiment, the delivery component 53 includes a delivery cylinder 531 vertically installed on the outside of the connecting rod 57. The output end of the delivery cylinder 531 is installed with a delivery suction cup 532. The delivery suction cup 532 is a pneumatic suction cup. Its principle is the existing technology and will not be repeated here. When in use, the delivery cylinder 531 is extended and retracted, thereby driving the delivery suction cup 532 to move up and down to achieve adsorption and grasping of the wafer.

[0082] During use, the positioned wafer is placed on the second wafer support 35, the positioned paper can is located on the turn plate 454, and the horizontal rodless cylinder 51 is retracted. At this time, the wafer is located directly below the delivery cylinder 531, and the delivery cylinder 531 is extended, driving the delivery suction cup 532 to adsorb the wafer. Then the delivery cylinder 531 is retracted, and the horizontal rodless cylinder 51 is extended to bring the delivery cylinder 531 to the top of the paper can. Then the lifting rodless cylinder 52 is extended, driving the connecting rod 57 to move downward, and then driving the delivery cylinder 531 installed on the connecting rod 57 to move downward, and the wafer is dropped into the paper can. Due to the two-stage design of the guide groove 541, the wafer first moves downward at an angle, and then moves vertically downward, which is convenient for delivering the wafer and reduces the jamming during delivery.

[0083] After the inclined delivery device 5 delivers the wafer into the paper can, the tablet pressing device 6 presses the wafer to the bottom of the paper can. The tablet pressing device 6 is installed on the frame 1 near the inclined delivery device 5. The tablet pressing device 6 in this embodiment includes a CNC lifting rod 61 and a pressing head 62. The CNC lifting rod 61 is installed on the frame 1. The CNC lifting rod 61 is located above the semicircular notch 4331 of the turntable 433. The pressing head 62 is fixed to the bottom of the CNC lifting rod 61. When the turntable 433 transfers the paper can with the wafer delivered to the bottom of the CNC lifting rod 61, the CNC lifting rod 61 works, driving the pressing head 62 to move downward, pressing the wafer to the bottom of the paper can. The CNC lifting rod 61 is a prior art, and its working principle is no longer described here.

[0084] Working principle: The paper can loading process of the present invention is divided into five steps: loading, positioning and conveying of discs, positioning and conveying of paper cans, tilting of discs and pressing. The discs and paper cans used are printed with logos that are easy for sensors to identify. By positioning the discs and paper cans, the pattern positions of the finished discs and paper cans are unified.

[0085] Loading: First, the staff puts the wafers in the first wafer supply bin 241 and the second wafer supply bin 242, selects the first wafer supply bin 241 or the second wafer supply bin 242 as the feeding station, and the other as the replenishing station. The height sensor 26 monitors the height of the wafers in the feeding station and adjusts the height of the wafers through the height adjustment component to make the height of the wafer feeding fixed. When the wafers in the feeding station are used up, the switching cylinder 221 works and drives the mounting frame 222 to slide along the switching slide 223, thereby realizing the switching of the wafer feeding station. The staff replenishes the wafers at the replenishing station, thereby realizing non-stop wafer feeding.

[0086] Wafer positioning and transportation: Then, the driving cylinder 321 extends, driving the mounting arm 331 to the wafer taking position. At this time, the first wafer taking cylinder 332 is located above the first wafer supply bin 241, and the second wafer taking cylinder 333 is located above the first wafer supporting rack 34; a wafer is placed in the first wafer supporting rack 34, and the wafer is adsorbed on the suction cup body 361 and rotates with it. When the wafer rotates to the appropriate position with the suction cup body 361, the wafer alignment sensor 37 recognizes the mark on the wafer, and the suction cup body 361 stops rotating; then the first wafer taking cylinder 332 and the second wafer taking cylinder 333 extend, driving the first wafer taking suction cup 334 and the second wafer taking suction cup 335 to move downward, and the first wafer taking suction cup 334 sucks the wafer placed on the first wafer supply bin 241. The second film-picking suction cup 335 sucks the wafer on the film bin 241, and then the first film-picking cylinder 332 and the second film-picking cylinder 333 contract, and the driving cylinder 321 contracts, driving the mounting arm 331 to move accordingly. When the first film-picking cylinder 332 moves above the first film-picking rack 34, the driving cylinder 321 stops working, and then the first film-picking cylinder 332 and the second film-picking cylinder 333 extend, driving the first film-picking suction cup 334 and the second film-picking suction cup 335 to move downward, and the first film-picking suction cup 334 places the sucked wafer on the first film-picking rack 34, and the second film-picking suction cup 335 places the sucked wafer on the second film-picking rack 35 for subsequent use by the tilting delivery device 5.

[0087] Paper can positioning and conveying: Next, place the unloaded paper can on the first conveying assembly 41. The first conveying assembly 41 conveys the unloaded paper can to the mounting plate 44 at the bottom of the arc-shaped conveying assembly 43. At this time, the paper can is clamped between the semicircular notch 4331 and the arc-shaped baffle 471. The conveying motor works to drive the turntable 433 to rotate, and then drives the paper can to rotate with the turntable 433. When the paper can to be processed is conveyed to the turntable 454, the conveying motor stops working, and the drive motor 451 works to drive the rotating shaft 453 to rotate, and drives the turntable 454 to rotate synchronously. The paper can alignment sensor 46 recognizes The mark on the paper can is detected and the recognized electrical signal is transmitted to the controller. The controller controls the driving motor 451 to stop working and the turntable 454 to stop rotating. The disc is dropped into the paper can through the inclined delivery device 5. After the delivery is completed, the conveying motor works to drive the turntable 433 to rotate, and then drives the paper can to rotate with the turntable 433. When the paper can reaches the second conveying component 42, due to the lack of the restriction of the arc-shaped baffle 471, the paper can is conveyed out by the second conveying component 42, and the positioning and conveying of the paper can are completed through the cooperation of the rotating component 45 and the paper can alignment sensor 46, so that the conveyed paper cans are in the same direction.

[0088] The wafer is dropped in an inclined manner: the positioned wafer is placed on the second wafer support 35, and the positioned paper can is placed on the turn plate 454. The horizontal rodless cylinder 51 is retracted. At this time, the wafer is located directly below the dropping cylinder 531, and the dropping cylinder 531 is extended, driving the dropping suction cup 532 to adsorb the wafer. Then the dropping cylinder 531 is retracted, and the horizontal rodless cylinder 51 is extended to bring the dropping cylinder 531 to the top of the paper can. Then the lifting rodless cylinder 52 is extended to drive the connecting rod 57 to move downward, and then drive the dropping cylinder 531 installed on the connecting rod 57 to move downward, and drop the wafer into the paper can. Due to the two-stage design of the guide groove 541, the wafer first moves downward at an angle and then moves vertically downward, which is convenient for dropping the wafer and reduces the jamming during dropping.

[0089] Tablet pressing: The turntable 433 transfers the paper can with the wafers to the bottom of the CNC lifting rod 61. The CNC lifting rod 61 works, driving the pressure head 62 to move downward, pressing the wafers to the bottom of the paper can. Finally, the paper can with the wafers is transported out by the second conveying assembly 42.
