Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] Example 1: Refer to Figure 1-19As shown, a packing and pushing device for a carton opener is disclosed. This device 5 includes a pushing mechanism assembly 501, a top packing mechanism 502, a fifth-station conveyor 503, and a buffer belt conveyor unit 504. The buffer belt conveyor unit 504 and the pushing mechanism assembly 501 are respectively arranged on the left and right sides of the pushing frame assembly 505. The pushing mechanism assembly 501 pushes the cigarette packs out of the carton 6 and feeds them onto the buffer belt conveyor unit 504. The buffer belt conveyor unit 504 consists of two sets joined together, with a first vertical baffle mechanism 574 at the joint. The two sets of buffer belt conveyor units 504 can buffer two independent cartons of cigarette packs, thereby increasing buffer capacity. The top clamping mechanism 502 and the fifth station conveyor 503 are respectively installed on the top and bottom middle of the smoke pushing frame assembly 501. The top clamping mechanism 502 is used to clamp the front and rear ends of the box 1 placed on the fifth station conveyor 503. The fifth station conveyor includes multiple rollers, a conveyor frame and a conveyor motor. The multiple rollers are evenly rotated and connected to the top of the conveyor frame. Adjacent rollers are connected and driven by a multi-wedge belt. One of the rollers is connected to the motor shaft of the conveyor motor through the multi-wedge belt. The conveyor motor is installed in the conveyor frame. Driven by the conveyor motor, all rollers are driven to rotate in one direction. It also includes a fifth parking device assembly 526 and an upper ear limiting mechanism. The fifth parking device assembly 526 includes an L-shaped baffle and a limiting telescopic cylinder. The baffle is fixedly connected to the upper ends of two stop-start guide rods. The two stop-start guide rods are connected to a crossbeam via stop-start linear bearings. The crossbeam is fixedly connected to the conveyor frame. The cylinder rod of the limiting telescopic cylinder is fixedly connected to the middle of the baffle. The two stop-start guide rods are arranged on both sides. The cylinder seat of the limiting telescopic cylinder is fixedly connected to the crossbeam. By the action of the limiting telescopic cylinder, the baffle is controlled to extend out of the roller 134 or retract, thereby realizing the parking and opening of the box. The baffle has an L-shaped cross section and good rigidity. The fifth parking device assembly 526 is installed on the fifth station conveyor 503 and extends out of the roller gap of the fifth station conveyor 503 for limiting. The upper ear limiting mechanism includes a smoke-pushing inlet guide rod 527, which is fixed by an inlet push rod plate 529. The dual-shaft end of the vertical telescopic dual-shaft cylinder 528 at the smoke-pushing inlet is connected to the smoke-pushing frame assembly 505 via the connecting seat 530. The smoke-pushing inlet guide rod 527 keeps the upper ear plate 7, which was opened in the previous process, in an open state. The end of the smoke-pushing inlet guide rod 527 facing the previous process has an outward arc-shaped bending structure, which plays a guiding role. When the cigarette box enters the fifth station conveyor, the box is conveyed by the fifth station conveyor and is limited at the fifth stop assembly 526, stopping the fifth station conveyor. The top clamping mechanism 502 clamps the front and rear ends of the box, and controls the smoke-pushing mechanism assembly 501 to push the cigarettes out of the box 6. The addition of two buffer belt conveyor units and the first vertical baffle mechanism for limiting and blocking isolation can buffer two boxes of cigarettes, ensuring the continuity of subsequent sorting and processing, and the production cycle is not affected, resulting in high sorting efficiency.

[0018] like Figure 6 As shown, the first vertical baffle mechanism 574 includes a first smoke baffle 575, a smoke baffle slide 576, a rodless cylinder 577, a smoke baffle guide rod 578, and a smoke baffle linear bearing 579. The first smoke baffle 575 has two sets of upper limit grooves 580 and lower limit grooves 581 embedded on its vertical sides. These two sets of upper limit grooves 580 and lower limit grooves 581 are respectively fixedly connected to both sides of the smoke pushing frame assembly 505 and located on the upper and lower sides of the belt of the buffer belt conveyor unit 504. The bottom of the first smoke baffle 575 is fixedly connected to the horizontal strip-shaped smoke baffle slide 576. The middle of the smoke baffle slide 576 is fixedly connected to the cylinder seat of the rodless cylinder 577. The two ends of the cylinder rod of the rodless cylinder 577 are vertically fixedly connected to the baffle frame 583 through the rodless cylinder seat 582. The baffle frame 583 is fixedly connected to the smoke pushing frame assembly 505. Two smoke guide rods 578 are used, which are connected to the two ends of the smoke baffle slide 576 near one side through two smoke baffle linear bearings 579. The two ends of the smoke baffle guide rods 578 are vertically fixed to the baffle frame 581 through guide rod seats 580. Two limit seats 584 are fixedly connected to the top of the smoke baffle slide 576. The baffle frame 581 is fixedly connected to the limit seats 584 near the bottom and to the limit posts 585. After the limit seats are lowered, they will rest on the limit posts. By controlling the rodless cylinder 577, the first smoke baffle 575 is pushed to move in a directional direction in the limit groove, which can realize the single-box strip buffer of the first buffer belt conveyor unit, prevent the entry of the truck buffer belt conveyor unit, and play the role of isolating the two smoke boxes. The limit groove plays the role of directional reinforcement of the smoke baffle, and the limit seats 582 and the limit posts play the role of limiting the descent of the smoke baffle.

[0019] Reference Figure 7-14 As shown, the smoke pushing mechanism assembly 501 includes a height-variable pusher head 506, a pusher head guide rod 508, a linear bearing 509, a support base 510, and a pusher head cylinder 507. The height-variable pusher head 506 includes an upper pusher head 532 and a lower pusher head 531; The pusher head 531 includes a base plate 5310, a front side plate 5311, a rear side plate 5312, and two upright plates 5313. The front side plate 5311 and the rear side plate 5312 are fixedly connected to the front and rear ends of the base plate 5310, respectively. The two upright plates 5313 are fixedly connected to both ends of the front side plate 5311 and the rear side plate 5312 and are fixedly connected to the base plate 5310. The two upright plates 5313 are provided with weight reduction holes 5314, and the rear side plate 5312 is provided with through holes for wires and air pipes to extend into. The pusher head with this structure has high support stability. The upper pusher head 532 is an inverted L-shaped plate. Its top plate bottom is connected to two upper pusher head linear bearings 587 via two vertical upper pusher head guide rods 586 and to the lower pusher head 531 via a lifting drive mechanism. The upper pusher head linear bearings 587 are fixedly connected to the inner side of the vertical plates 5313 set on the left and right sides of the lower pusher head 531. The vertical plate of the upper pusher head 532 is attached to the front side plate 5311 set on the front side of the lower pusher head 531. The lifting drive mechanism is installed on the lower pusher head 531 and can drive the upper pusher head 532 to move up and down. During the lifting and lowering process, the vertical plate of the upper pusher head 532 always keeps in contact with the front side plate 5311 (the maximum lifting amount can ensure that partial contact and overlap are always maintained), which improves the rigidity and pushing stability of the cigarette pack. Four pusher guide rods 508 are used, with one end symmetrically fixedly connected to the rear side plate 5312 located near the four corners on the rear side of the lower pusher 531; four linear bearings 509 are used, correspondingly sleeved on the four horizontally arranged pusher guide rods 508; the support base 510 is fixedly connected to the four linear bearings 509; the cylinder rod of the pusher cylinder 507 is fixedly connected to the rear side plate 5312 through a flange fixedly connected to it, the cylinder seat of the pusher cylinder 507 is fixedly connected to the support base 510, and the support base 510 is fixedly connected to the smoke pusher support frame 511.

[0020] During the process of pushing out cigarette packs opened on one side, the inventors found that the existing variable lifting pusher head with a comb-tooth structure was prone to jamming, making it difficult to achieve stable pushing. Therefore, improvements were made by attaching the vertical plate of the upper pusher head to the front plate set on the front side of the lower pusher head. This increases the rigidity of the pusher head's pushing part, thereby enabling a smooth and reliable pushing of the cigarette packs and improving the pushing reliability of the cigarette pushing mechanism. Furthermore, the upper pusher head guide rod and upper pusher head linear bearing are added to connect to the two vertical plates, increasing the lifting and supporting stability of the upper pusher head and avoiding the excessive cantilever and weak rigidity caused by the original upper pusher head only being connected by a slider guide pair. This design addresses the issue of inconsistent pusher head height, thereby improving the overall pushing rigidity and strength of the pusher head. Furthermore, the cylinder provides elastic buffering protection to prevent damage to the cigarette packs. The height-adjustable pusher head can adapt to pushing out cigarette packs from boxes of varying heights and sizes. Increasing the pushing area results in more stable pushing. The height can be adjusted according to the size of the cigarette box, making adjustment convenient and quick. The 507 pusher head cylinder drives the variable pusher head to move along the pusher head guide rod and pusher head linear bearing, entering the box to push out the cigarette packs. The movement is smooth and reliable. The height-adjustable pusher head enables pushing out cigarette packs from boxes of varying heights, reducing costs, increasing the contact area, and making pushing more stable.

[0021] Specifically, the lifting drive mechanism includes a lifting pusher cylinder 588, a vertical sliding plate 589, a vertical linear slider guide rail pair 534, a pusher screw and nut pair 535, a belt drive mechanism 536, and a lifting drive motor 537. The lifting pusher cylinder 588 is a dual-shaft cylinder, with its two output shafts fixedly connected to the bottom of the horizontal plate of the upper pusher 532 via a flange 533. The cylinder seat of the lifting pusher cylinder 588 is fixedly connected to the front side of the vertical sliding plate 589. The slider of the vertical linear slider guide pair 534 is fixedly connected to the rear side of the vertical sliding plate 589, and the guide rail of the vertical linear slider guide pair 534 is fixedly connected to the rear plate 5312. The nut of the pusher screw nut pair 535 is fixedly connected to the rear side of the vertical sliding plate 589, and the two ends of the pusher screw nut pair 535 are connected to the vertical sliding plate 589. The bearing housing is rotatably connected to the front side of the rear side plate 5312; the driven pulley of the belt drive mechanism 536 is fixedly connected to the lower end of the lead screw of the push head lead screw nut pair 535 extending out of the bearing housing; the motor shaft of the lifting drive motor 537 is fixedly connected to the driving pulley of the belt drive mechanism 536, and the housing of the lifting drive motor 537 is fixedly connected to the base plate 5310 of the lower push head 531 through the motor frame. Through the double lifting formed by the lifting push head cylinder and the lead screw nut, the lifting height is higher, which can adapt to the pushing of cigarette packs stacked in the higher box, and the pushing is more stable and reliable.

[0022] Specifically, a flexible rubber limit post 538 is installed directly below the slider of the vertical linear slider guide rail pair 534. The rubber limit post 538 is fixedly connected to the base plate of the lower push head. The flexible rubber limit post 538 prevents the slider from detaching from the guide rail during the descent process and plays an elastic buffer protection role.

[0023] The vertical sliding plate 589 is fixedly connected to the slider of the vertical linear slider guide pair 534 by a pad.

[0024] The rear side panel 5312 and the front side panel 5311 are fixedly connected at both ends by the upright plate 5313.

[0025] Rubber pusher head 1 590 and rubber pusher head 2 591 are fixedly connected to the front side of the vertical plate of the upper pusher head 531 and the lower front side of the front plate 5311 of the lower pusher head 532, respectively. Rubber pusher head 1 590 and rubber pusher head 2 591 are fixedly connected to the front side of the vertical plate of the upper pusher head 531 and the front side of the front plate 5311 of the lower pusher head 532 respectively through two columns. During the process of pushing the cigarette pack, the rubber heads avoid damaging the cigarette pack shell. The column connection realizes a suspended structure, which is more conducive to playing an elastic buffer role. Rubber pusher head 1 590 and rubber pusher head 2 591 are provided with a sloping surface 592 facing the side of the box, which facilitates the guiding role.

[0026] To ensure smooth cigarette ejection and avoid the impact of the lower ear resetting, an inlet lower ear pressing limit plate 539 is installed below the cigarette pushing mechanism assembly 501. The inlet lower ear pressing limit plate 539 is fixedly connected to the cylinder rod connecting plate 541 of the lower ear limiting directional telescopic cylinder 540. The cylinder seat of the lower ear limiting directional telescopic cylinder 540 is fixedly connected to the cigarette pushing support frame 511 through the cylinder seat bracket 542. The inlet lower ear pressing limit plate 539 faces the previous process section and opens outward to facilitate its guiding function, allowing the lower ear opened in the previous process to continuously enter the current station and remain open. The open lower ear avoids the impact during the cigarette ejection process and the problem of difficulty in maintaining downward tilting due to its own weight.

[0027] Reference Figure 15-16As shown, the top clamping mechanism 502 includes two clamping plates 512, which are vertically fixed to the bottom of two horizontal hanging plates 513. Both clamping plates 512 have a rubber layer 543 on their inner sides, which increases friction and makes clamping more stable and reliable. Reinforcing ribs are provided on the back of both clamping plates 512 to improve clamping rigidity. Both hanging plates 513 are connected to the front and rear parts of the upper surface of the lifting main plate 515 via a slider guide pair 514. The lifting main plate 515 has a U-shaped notch 502 larger than the width of the clamping plate corresponding to the clamping plate 512. 16. The lifting main board 515 is fixedly connected to the upper pull plate 518 via four lifting rods 517. The upper pull plate 518 is connected to the clamp bracket 520 via the clamp lifting assembly 519. The clamp bracket 520 is a gantry structure, with its two lower ends fixedly connected to the top of the smoke pushing frame assembly 505. It also includes side ear suction cups 521 for adsorbing and pushing material side ears. Two sets of side ear suction cups 521 are provided, and each set of side ear suction cups 521 is fixedly connected to the connecting seat 522. The connecting seat 522 is an inverted L-shape, with its upper free end fixedly connected to the lower end of the inverted L-shaped crank arm shaft 523. The upper free end of 523 is connected to the rotary cylinder 525 via a flange shaft 524. The rotary cylinder 525 is fixedly connected to the bottom of the extension section of the hanging plate 513 facing the cigarette pushing mechanism. The rotary cylinder is controlled to rotate. When the suction cups adhere to the two ears, the rotary cylinder is controlled to rotate in the opposite direction to open the two ears, thereby reducing the obstruction force during the pushing of the cigarette and providing pushing stability and reliability. The clamp lifting assembly 519 includes a clamp lifting cylinder 544, a clamp lifting guide rod 545, and a clamp mounting plate 546. The cylinder rod of the clamp lifting cylinder 544 is hinged to the upper pull plate 5. On the hinged double ears of clamp 18, the cylinder seat of clamp lifting cylinder 544 is fixedly connected to clamp mounting plate 546. Clamp mounting plate 546 is fixedly connected to the top of clamp bracket 520. There are two clamp lifting guide rods 545, with the lower end fixedly connected to the upper pull plate 518. The clamp lifting guide rods 545 are connected to clamp mounting plate 546 through linear bearings. Clamp lifting cylinder 544 drives upper pull plate 518 to move up and down along clamp lifting guide rod 545, thereby realizing the up and down movement of two clamping plates 512 installed below upper pull plate 518, realizing the rapid adjustment of clamping height.

[0028] Each buffer conveyor belt unit 504 is equipped with a buffer centering component 547 and a lifting baffle assembly 548. The buffer centering component 547 is located above the middle of the buffer conveyor belt unit 504 and can center the pushed-out cigarette packs. The lifting baffle assembly 548 is installed at the outlet of the buffer conveyor belt unit 504 and is used to limit and block the pushed-out cigarette packs. The buffer centering component 547 includes a buffer centering guide rod 549, a left guide plate assembly 550, a right guide plate assembly 551, a linkage mechanism, and a power mechanism. There are two buffer centering guide rods 549, with their two ends fixedly connected to the left fixed plate 552 and the right fixed plate 553, respectively. The left fixed plate 552 and the right fixed plate 553 are fixedly connected to the frame of the buffer conveyor belt unit 504. The centering guide rods 549 are symmetrically connected to the left guide plate assembly 550 and the right guide plate assembly 551 via linear bearings. The left guide plate assembly 550 and the right guide plate assembly 551 are connected to the power mechanism via a linkage mechanism. The power mechanism performs relative movement of the left and right guide plates through the linkage mechanism, thereby achieving centering of the cigarette pack. The linkage mechanism includes a linkage seat plate 554, a drive pin 555, a drive connecting rod 556, and a linkage crank 557. The middle part of the linkage crank 557 is rotatably connected to the upper side of the middle part of the linkage seat plate 554, and two drive connecting rods 556 are respectively hinged to the two free ends. The other end of each drive connecting rod 556 is hinged to the drive pin 555. The drive pin 555 slides through a long strip on the linkage seat plate 554 along its length. The guide pin hole 558 is fixedly connected to the left guide plate assembly 550 or the right guide plate assembly 551. The two ends of the connecting rod seat plate 554 are fixedly connected to the profile frame 559. The profile frame 559 is fixedly connected to the frame of the buffer belt conveyor unit 504. The drive pin moves along its length in the guide pin hole, thereby synchronously driving the left guide plate assembly 550 and the right guide plate assembly 551 to move synchronously relative to each other. The drive pin is connected to the power mechanism, which includes a synchronous transmission belt conveyor 560. The synchronous transmission belt conveyor 560 is mounted on the servo mounting plate 561 located above the connecting rod seat plate 554. The synchronous transmission belt conveyor 560 is connected to the synchronous belt motor 563 through the synchronous transmission belt conveyor 562. The synchronous belt motor 563 is fixed. Connected to the servo mounting plate 561, the belt of the synchronous drive belt conveyor 560 is fixedly connected to the upper horizontal section 565 of the bow-shaped drive plate 564. The lower horizontal section 566 of the bow-shaped drive plate 564 is fixedly connected to one of the drive pins 555 and located between the left guide plate assembly 550 or the right guide plate assembly 551 and the connecting rod seat plate 554. This improves the driving stability of the drive plate 564. Through the transmission of the synchronous belt, the bow-shaped drive plate 564 is driven to move horizontally, which in turn drives the drive pin to move horizontally, achieving the clamping and centering of the cigarette packs.
