Description

Technical Field

[0001] This invention relates to the field of can-making equipment technology, specifically to a packaging production line for feeding and unloading workpiece lids. Background Technology

[0002] In the production process of beer caps, can caps, and other workpiece caps, after the beer caps are formed and pass inspection, they need to be packaged for subsequent storage and transportation.

[0003] Currently, the packaging methods for workpiece covers mostly involve manual packaging by workers or conveyor equipment for transporting, packaging, and stacking. These existing packaging methods have the following shortcomings during use:

[0004] 1) Manual packaging is inefficient, labor-intensive, and has poor stacking accuracy, which can easily cause beer caps to tip over.

[0005] 2) When simple conveying equipment is used for conveying, packing and stacking, the workpiece caps, especially beer caps, lack effective guiding and limiting structures during the falling process. This causes the beer caps to shake and shift, which not only affects the neatness of the stack, but may also cause scratches on the surface of the beer caps, reducing product quality. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to address the deficiencies of the existing technology by providing a packaging production line that can realize automated feeding, delivery, packaging and stacking of workpiece covers, improve the stability of the packaging process, and avoid scratches on the workpiece covers.

Detailed Implementation

[0036] The present invention will now be described in detail with reference to the accompanying drawings, which form part of this specification. The principles of the invention are illustrated by means of embodiments, and other aspects, features, and advantages of the invention will become apparent from this detailed description. In the accompanying drawings, the same or similar parts in different figures are indicated by the same reference numerals.

[0037] like Figures 1-8As shown, Embodiment 1 of the present invention provides a packaging production line for feeding, unloading, and loading workpiece cover 5. The packaging production line includes a feeding conveyor 1, a feeding rotary device 2, an unloading device 3, and a packaging and stacking device 4. The feeding rotary device 2 is fixed between the feeding conveyor 1 and the unloading device 3. The end of the feeding conveyor 1 is connected to the feeding end of the feeding rotary device 2. The unloading device 3 is located above the discharge end of the feeding rotary device 2 and is arranged opposite to the feeding conveyor 1. The packaging and stacking device 4 is fixed below the unloading device 3 and is located on one side of the feeding rotary device 2. The packaging and stacking device 4 includes a workpiece stacking turntable 41 and several material rods 42. The several material rods 42 are fixed to the workpiece stacking turntable 41 at intervals and are located below the unloading device 3. The packaging production line of this invention achieves a fully automated operation process from feeding, conveying, transferring, and unloading the qualified workpiece cover 5 to unloading, stacking, and packaging through the coordinated operation of the feeding conveyor 1, feeding rotation device 2, unloading device 3, and packaging stacking device 4. It completely eliminates the traditional methods of manual transfer and manual packaging stacking. The qualified workpiece cover 5 is directly conveyed to the feeding rotation device 2 by the feeding conveyor 1, and the transfer can be completed without manual intervention. Then, the unloading device 3 accurately presses down the cover. The whole process is automated, which effectively improves the packaging efficiency and meets the continuous packaging operation requirements of large-scale production of workpiece cover 5. Compared with manual packaging, the efficiency is greatly improved. This invention precisely connects the feeding rotary device 2 to the end of the feeding conveyor 1 and the unloading device 3, respectively, to achieve a smooth transition of the workpiece cover 5 from conveying to the unloading stage, avoiding scattering or displacement during the transfer process. Several material rods 42 in the packaging and stacking device 4 are fixed to the workpiece stacking turntable 41 and precisely correspond to the area below the unloading device 3. After being pressed down by the unloading device 3, the workpiece cover 5 can be stacked sequentially along the axial direction of the material rods 42. The packaging production line of this invention adopts a packaging process of "conveyoring, transfer, unloading, and stacking." The feeding conveyor 1 and the feeding rotary device 2 are precisely connected to the end of the feeding conveyor 1 and the unloading device 3, respectively, to achieve a smooth transition of the workpiece cover 5 from conveying to the unloading stage, avoiding scattering or displacement during the transfer process. The feeding end of the rotating feeding device 2 is connected to the material feeding device 3, which is located above the discharge end of the rotating feeding device 2 and opposite to the feeding conveyor 1. The packaging and stacking device 4 is located below the material feeding device 3 and on one side of the rotating feeding device 2. The structure is compact and the transmission path is short, which reduces the energy loss and positional deviation of the workpiece cover 5 during the conveying process. The material rod 42 is fixedly connected to the workpiece stacking turntable 41, which is structurally stable and not prone to loosening or deformation during long-term high-frequency stacking operations, thus improving the stability and service life of the production line. Through the cooperation of the rotating cover feeding mechanism and the workpiece stacking turntable 41 with multiple material rods 42, continuous and efficient batch packaging operations are achieved, which significantly improves production efficiency and reduces labor costs.

[0038] In this embodiment of the invention, several material rods 42 are vertically fixed to the workpiece stacking turntable 41 in a circular array around the axis of the workpiece stacking turntable 41. A connecting seat 411 is fixed around the workpiece stacking turntable 41, and the connecting seat 411 is provided with a slot that cooperates with the material rods 42. The slot is provided so that the bottom of the material rod 42 can be inserted into the connecting seat 411. By fixing the material rods 42 in a circular array, the force can be evenly distributed when the workpiece cover 5 is stacked, effectively avoiding problems such as misalignment and tilting, and significantly improving the stacking regularity, which provides convenience for subsequent packaging operations.

[0039] The feeding rotation device 2 of the present invention includes a machine base 21 and a rotation drive structure 22 and a feeding turntable 23 fixed on the machine base 21. The rotation drive structure 22 is fixed above the feeding turntable 23 and connected to the middle of the feeding turntable 23. The feeding turntable 23 is provided with a plurality of clamping grooves 231, which are distributed at intervals along the periphery of the feeding turntable 23. In an embodiment of the present invention, a plurality of arc-shaped clamping grooves 231 are uniformly arranged on the edge of the feeding turntable 23. The size of the clamping grooves 231 is adapted to the outer diameter of the workpiece cover 5, ensuring that the workpiece cover 5 can be stably clamped in the clamping grooves 231 and rotate with the feeding turntable 23. A magnet 232 is fixed at each clamping groove 231 to firmly clamp the workpiece cover 5.

[0040] The rotary drive structure 22 includes a rotary motor 221, a reducer 222, a coupling 223, and a feeding shaft 224. The input end of the reducer 222 is connected to the motor shaft of the rotary motor 221. The coupling 223 is located between the reducer 222 and the feeding shaft 224. One end of the feeding shaft 224 is connected to the output end of the reducer 222 via the coupling 223, and the other end of the feeding shaft 224 is fixed to the center of the feeding turntable 23. The power of the rotary motor 221 is transmitted sequentially to the feeding turntable 23 via the reducer 222, coupling 223, and feeding shaft 224 to drive the feeding turntable 23 to rotate. The coupling 223 is a flexible coupling. The feeding turntable 23 is fixed to the feeding shaft 224 via a key connection. The rotary motor 221 can be a servo motor or a stepper motor. In this embodiment of the invention, the rotary motor 221 is preferably a servo motor, and the rotary drive structure 22 is driven by the servo motor. The rotation speed is matched with the conveying speed of the feeding conveyor 1 to achieve precise positioning of the feeding turntable 23. This ensures that the material slot 231 of the feeding turntable 23 is precisely connected with the end of the feeding conveyor 1 and the unloading device 3. The feeding end of the feeding rotary device 2 is aligned with the end of the feeding conveyor 1, and the discharge end corresponds to the position directly above the unloading device 3.

[0041] In this invention, a first sensor 24 and a first bracket 25 are fixed above the feed end of the feeding rotary device 2. The first sensor 24 is fixed to the machine base 21 through the first bracket 25. A second sensor 26 and a second bracket 27 are fixed above the discharge end of the feeding rotary device 2. The second sensor 26 is fixed to the machine base 21 through the second bracket 27.

[0042] The material feeding device 3 of the present invention includes a feeding head 31, a feeding cylinder 32, and a cylinder fixing plate 33. The top of the feeding cylinder 32 is fixed to the machine base 21 by the cylinder fixing plate 33 and is located above the discharge end of the feeding turntable 23. The telescopic rod of the feeding cylinder 32 is connected to the top of the feeding head 31. Preferably, the feeding cylinder 32 of the present invention is a telescopic cylinder. The material feeding device 3 extends and retracts through the telescopic rod of the feeding cylinder 32, thereby driving the feeding head 31 to rise and fall, so as to realize the pressing of the feeding head 31 against the workpiece cover 5 at the discharge end of the feeding rotary device 2, and realize the material feeding operation of the workpiece cover 5.

[0043] In its specific implementation, the packaging and stacking device 4 includes a packaging auxiliary cover structure 43, a material collection limiting channel 44, and a cover positioning structure 45. The material collection limiting channel 44 is fixed below the material dropping device 3. Both the packaging auxiliary cover structure 43 and the cover positioning structure 45 are installed below the material collection limiting channel 44, and the cover positioning structure 45 is positioned opposite to the packaging auxiliary cover structure 43. The packaging auxiliary structure can extend to block the material collection limiting channel 44 to provide temporary support for the falling workpiece cover 5. The workpiece stacking turntable 41 rotates the material rod 42 to directly below the material dropping device 3. The material collection limiting channel 44 is located on both sides of the material rod 42. The packaging auxiliary cover structure 43 extends and locks onto the material rod 42. At this time, the packaging auxiliary cover structure 43 extends to block the material collection limiting channel 44, so that the material dropping device 3 presses down the workpiece cover 5 at the discharge end of the feeding turntable 23, causing the workpiece cover 5 to fall onto the material rod 42 directly below the material dropping device 3. By setting up a packaging auxiliary structure and a cover structure, the first workpiece cover 5 can be accurately positioned and supported in the initial stage of cover placement, and together with the material collection limiting channel 44, the stability and accuracy of the entire cover placement process can be ensured.

[0044] The material collection and limiting channel 44 of the present invention includes two channel plates 441 arranged opposite to each other and a driving assembly 442 for driving the relative movement of the two channel plates 441. The gap between the two channel plates 441 forms a limiting channel for the workpiece cover 5 to fall into the material rod 42. Through the limiting channel formed by the two relatively movable channel plates 441, the material collection and limiting channel 44 of the present invention allows the driving assembly 442 to control the two channel plates 441 to move closer together during the process of the workpiece cover 5 falling onto the material rod 42. This creates a "hugging" limiting effect on the stack of workpiece covers 5 on the material rod 42 from the side, effectively preventing the material rod 42 from shaking during the process of the workpiece cover 5 falling into the material rod 42, keeping the material rod 42 upright, and also preventing scratches on the workpiece cover 5 during the process of falling into the material rod 42. This ensures that the workpiece cover 5 falls upright and neatly onto the material rod 42 for stacking, guaranteeing the packaging quality of the workpiece cover 5. In this embodiment of the invention, the driving assembly 442 preferably consists of two sets of telescopic cylinders. The channel plate 441 is configured in an arc shape, and the end of the telescopic rod of each set of telescopic cylinders is connected to a corresponding channel plate 441. By controlling the extension and retraction of the telescopic cylinders, the two channel plates 441 can be driven to move closer or separate. When the two channel plates 441 move closer, the gap between the two channel plates 441 forms a limiting channel with a diameter slightly larger than the outer diameter of the workpiece cover 5 on the material rod 42. This limiting channel can hold the workpiece cover 5 tightly, playing a role in limiting and straightening.

[0045] In other embodiments, the inner wall of the channel plate 441 can be made smooth to prevent the workpiece cover 5 from being scratched and to effectively protect the surface quality of the workpiece cover 5.

[0046] like Figures 9-14The packaging auxiliary cover structure 43 of the present invention includes a packaging fork support plate 431, a support plate fixing seat 432, a packaging auxiliary lifting mechanism 433, a support frame 434, and a cover moving mechanism 435. The packaging fork support plate 431 is fixed to the upper end of the support frame 434 through the support plate fixing seat 432. One side of the packaging fork support plate 431 is connected to the packaging auxiliary lifting mechanism 433 so as to drive the packaging fork support plate 431 to move up and down along the vertical direction of the support frame 434. The cover moving mechanism 435 is located on one side of the support frame 434 and connected to the support frame 434. The cover moving mechanism 435 drives the support frame 434 and the support plate fixing seat 432 and the packaging fork support plate 431 to move horizontally as a whole. In this embodiment of the present invention, the support frame 434 is located below the material dropping device 3 and on one side of the workpiece stacking turntable 41. The cover moving mechanism 435 includes a moving cylinder 4351, a connecting plate 4352, a sliding plate 4353, a moving slider 4354, and a moving slide rail 4355. The bottom of the support frame 434 is fixed to the top of the sliding plate 4353. The moving slider 4354 is fixed to the bottom of the sliding plate 4353 and slidably connected to the moving slide rail 4355. One end of the connecting plate 4352 is connected to the piston rod of the moving cylinder 4351, and the other end of the connecting plate 4352 is connected to the sliding plate 4353. The piston rod of the moving cylinder 4351 extends or retracts to drive the connecting plate 4352, the sliding plate 4353, the support frame 434, the support plate fixing seat 432, and the packing fork support plate 431 to move horizontally along the moving slide rail 4355, thereby realizing the extension and retraction of the packing fork support plate 431.

[0047] The packaging auxiliary lifting mechanism 433 of the present invention includes a power motor 4331, a drive wheel 4332, a driven wheel 4333, a transmission belt 4334, and a belt clamping block 4335. The driven wheel 4333 and the drive wheel 4332 are respectively fixed at the upper and lower ends of the support frame 434. The output shaft of the power motor 4331 is fixedly connected to the drive wheel 4332. The transmission belt 4334 is sleeved on the drive wheel 4332 and the driven wheel 4333 and is connected to them in a transmission manner. One end of the belt clamping block 4335 is fixed to the side of the transmission belt 4334, and the other end of the belt clamping block 4335 is fixed to the pallet fixing seat 432. The pallet fixing seat 432 is fixed to one side of the transmission belt 4334 through the belt clamping block 4335. The packing auxiliary lifting mechanism 433 also includes a motor mounting base 4338 and a synchronous pulley bracket 4339. The motor mounting base 4338 is fixed to the lower end of the support frame 434. The drive wheel 4332 is fixed to one side of the motor mounting base 4338, and the power motor 4331 is fixed to the other side of the motor mounting base 4338. The motor mounting base 4338 has an opening. The output shaft of the power motor 4331 passes through the opening of the motor mounting base 4338 and is fixedly connected to the drive wheel 4332. The synchronous pulley bracket 4339 is fixed to the upper part of the support frame 434, and the driven wheel 4333 is fixed to the upper part of the support frame 434 through the synchronous pulley bracket 4339. The packaging auxiliary lifting mechanism 433 includes a lifting slide rail 4336 and a lifting slider 4337. The lifting slide rail 4336 is arranged along the vertical direction of the support frame 434 and is fixed on the support frame 434. The lifting slider 4337 is fixedly connected to one side of the pallet fixing seat 432. The lifting slider 4337 is slidably sleeved on the lifting slide rail 4336 and moves up and down reciprocally along the lifting slide rail 4336.

[0048] In this embodiment of the invention, the cover positioning structure 45 includes a cover cylinder 451 and a positioning block 452, with the telescopic rod of the cover cylinder 451 fixed to the positioning block 452. The extension and retraction of the telescopic rod of the cover cylinder 451 causes the positioning block 452 on the telescopic rod to extend and retract, so that the positioning block 452 extends to one side of the packing fork support plate 431. The cover cylinder 451 and positioning block 452 provided in this invention can prevent the workpiece cover 5 from falling off the other side of the packing fork support plate 431. The packaging auxiliary cover structure 43 of the present invention uses a horizontally retractable packaging fork support plate 431. During the initial cover drop, the packaging fork support plate 431 can extend and temporarily lock onto the empty material rod 42. The telescopic rod of the cover cylinder 451 drives the positioning block 452 to extend to the other side of the packaging fork support plate 431. The packaging fork support plate 431 provides support and positioning for the first falling workpiece cover 5. The cover positioning structure 45 is used to prevent the workpiece cover 5 from accidentally falling off the other side of the packaging fork support plate 431.

[0049] In a specific implementation of the present invention, the packing and stacking device 4 includes a rotation drive structure 46, which is connected to the workpiece stacking turntable 41. The rotation drive structure 46 includes a drive mechanism 461, a synchronous driving wheel 462, a synchronous driven wheel 463, a synchronous belt 464, and a turntable central shaft 465. The synchronous driven wheel 463 and the turntable central shaft 465 are both fixed to the center of the workpiece stacking turntable 41. The drive mechanism 461 and the synchronous driving wheel 462 are disposed around the periphery of the workpiece stacking turntable 41. The drive mechanism 461 is fixedly connected to the synchronous driving wheel 462. The synchronous belt 464 is sleeved on the synchronous driving wheel 462 and the synchronous driven wheel 463 and is connected to them for transmission. The turntable central shaft 465 is connected to the center of the synchronous driven wheel 463. In this embodiment of the invention, the drive mechanism 461 includes a drive motor 4611, a planetary reducer 4612, and a support plate 4613. The top of the support plate 4613 is provided with a through hole, and the synchronous drive wheel 462 is placed inside the fixed cover. The drive motor 4611 and the planetary reducer 4612 are both located above the support plate 4613. The input end of the planetary reducer 4612 is connected to the motor shaft of the drive motor 4611. The output end of the planetary reducer 4612 passes through the through hole of the support plate 4613 and is connected to the synchronous drive wheel 462. The power of the drive motor 4611 is transmitted to the workpiece stacking turntable 41 in sequence through the planetary reducer 4612, the synchronous drive wheel 462, the synchronous belt 464, the synchronous driven wheel 463, and the turntable central shaft 465, so as to drive the workpiece stacking turntable 41 to rotate.

[0050] The lifting principle of the pallet fixing seat 432 and the packing fork pallet 431 on it is as follows:

[0051] When the power motor 4331 starts, it drives the drive wheel 4332 to rotate, which in turn drives the driven wheel 4333 to rotate via the transmission belt 4334. Since the belt clamping block 4335 fixes one side of the transmission belt 4334 to the pallet fixing seat 432, when the transmission belt 4334 circulates between the drive wheel 4332 and the driven wheel 4333, the belt clamping block 4335 moves along with the transmission belt 4334, thereby causing the entire pallet fixing seat 432 and its packing fork pallet 431 to move together. Specifically, when the transmission belt 4334 moves in one direction (e.g., upward), the belt clamping block 4335 causes the pallet fixing seat 432 to rise; when the transmission belt 4334 moves in the opposite direction (e.g., downward), the belt clamping block 4335 causes the pallet fixing seat 432 and its packing fork pallet 431 to fall as a whole. During the lifting and lowering process of the pallet fixing seat 432 and the packing fork pallet 431, the lifting slider 4337 fixed to one side of the pallet fixing seat 432 will slide up and down along the lifting slide rail 4336 fixed on the support frame 434. The guide pair composed of the lifting slide rail 4336 and the lifting slider 4337 plays a key role in constraint and guidance, which can limit the movement of the pallet fixing seat 432 to the vertical direction, effectively preventing the pallet fixing seat 432 from swinging and twisting back and forth or left and right during the lifting and lowering process, ensuring the stability and positional accuracy of the lifting and lowering process, and bearing the bending moment and lateral force generated by the pallet fixing seat 432 and its load, ensuring the rigidity and operational reliability of the entire packing auxiliary lifting mechanism 433.

[0052] In other embodiments, the number of lifting slide rails 4336 can be set to two, with the two lifting slide rails 4336 symmetrically arranged on both sides of the support frame 434, and correspondingly equipped with two lifting sliders 4337, so as to form a double guide support, further increasing the stability and load-bearing capacity of the lifting process.

[0053] In specific implementation, the packaging auxiliary cover structure 43 of the present invention includes a third sensor 436 and a third bracket 437. The third bracket 437 is fixed to the upper end of the support frame 434 of the cover moving mechanism 435 and located below the material collection limiting channel 44. The third sensor 436 is fixed to the upper end of the support frame 434 of the cover moving mechanism 435 through the third bracket 437. The third sensor 436 is electrically connected to the power motor 4331. When the third sensor 436 detects workpiece covers 5 falling into the material rod 42 in sequence, the third sensor 436 sends a signal to the power motor 4331 of the packaging auxiliary cover structure 43, causing the power motor 4331 to drive the pallet fixing seat 432 and the packaging fork pallet 431 on it to descend as a whole by the height of one workpiece cover 5.

[0054] The packaging auxiliary cover structure 43 of the present invention also includes a fourth sensor 438 and a fourth bracket 439. The fourth bracket 439 is fixed to the lower end of the support frame 434 of the cover moving mechanism 435 and located at the bottom of the material rod 42. The fourth sensor 438 is fixed to the lower end of the support frame 434 of the cover moving mechanism 435 through the fourth bracket 439. The fourth sensor 438 is electrically connected to the drive motor 4611 of the drive mechanism 461. When the workpiece cover 5 dropped by the fourth sensor 438 has slid to the bottom position of the material rod 42, it indicates that the number of workpiece covers 5 stacked on the material rod 42 has reached a certain amount. The fourth sensor 438 will send a signal to the drive motor 4611 of the drive mechanism 461, causing the drive motor 4611 to drive the workpiece stacking turntable 41 to rotate, so that the workpiece stacking turntable 41 rotates the next empty material rod 42 to the bottom of the dropping device 3, and so on in a cycle.

[0055] The working process of the packaging production line of this invention is as follows:

[0056] First, the qualified workpiece cover 5 is conveyed to the feeding turntable 23 via the feeding conveyor 1;

[0057] Secondly, the feeding turntable 23 rotates, transporting the workpiece cover 5 sequentially to the bottom of the unloading device 3. At the same time, the workpiece stacking turntable 41 rotates, rotating an empty material rod 42 to the bottom of the unloading device 3. At this time, the two channel plates 441 of the material collection limiting channel 44 are brought together by the drive component 442, so that the two channel plates 441 hug the material rod 42 area of ​​the station from both sides. The packaging auxiliary cover structure 43 extends out, is stuck on the material rod 42 and is located at the lower end of the material collection limiting channel 44. The telescopic rod of the cover cylinder 451 drives the positioning block 452 to extend, so that the positioning block 452 extends to the packaging fork support plate 431.

[0058] Then, the feeding cylinder 32 of the feeding device 3 is activated, driving the feeding head 31 of the feeding cylinder 32 to press down the workpiece cover 5 located below it, so that it falls into the feeding rod 42. During the process of the cover falling, due to the embracing effect of the material collection limiting channel 44, the workpiece cover 5 that is being stacked on the feeding rod 42 is effectively constrained, avoiding shaking and ensuring the uprightness of the feeding rod 42.

[0059] Finally, when the number of workpiece covers 5 on a material bar 42 reaches the predetermined quantity, the packaging auxiliary cover structure 43 retracts, the workpiece stacking turntable 41 rotates one station, and the next empty material bar 42 is rotated into the unloading station position. At the same time, the material bar 42 that has been stacked is rotated out for subsequent bundling or unloading operations. This cycle is repeated to achieve continuous automated packaging processing.

[0060] Compared with the prior art, the technical solution disclosed in the above embodiments has the following beneficial effects:

[0061] In the above embodiments, the packaging production line of the present invention achieves full automation from the input of qualified workpiece covers 5 to the final bundled stacking through the coordinated operation of the feeding conveyor 1, the feeding rotation device 2, the dropping device 3, and the packaging stacking device 4. The continuous rotational conveying of the feeding rotation device 2 and the precise pressing action of the dropping device 3 work together to enable the workpiece covers 5 to be quickly and orderly inserted into the material bar 42, completely replacing the traditional manual capping operation, thus improving packaging efficiency. The feeding rotation device 2 is cleverly set between the feeding conveyor 1 and the dropping device 3, forming a smooth material transfer hub. The action connection between each component is optimized, reducing the occurrence of malfunctions such as cap jamming and cap blockage, and ensuring the long-term stability and reliability of the automatic packaging production line. The use of automated cap dropping and bar insertion method allows the workpiece covers 5 to be stacked on the material bar 42, which is beneficial for subsequent packaging, storage, and transportation. One automatic packaging production line can replace multiple operators, which not only directly reduces labor costs but also reduces indirect costs caused by personnel management and training.

[0062] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
