Description

Technical Field

[0001] This utility model relates to the field of filling and sealing technology, specifically to a rotary filling and sealing machine. Background Technology

[0002] In the food filling industry, especially in coffee production, filling machines are widely used. Common filling machines include single-row linear coffee filling machines, two-row coffee filling machines, four-row coffee filling machines, and six-row coffee filling machines. However, traditional filling machines have drawbacks such as excessively long production lines, large footprints, complex equipment, high cost, inconvenient operation and maintenance, and generally low filling accuracy.

[0003] Chinese utility model patent publication number "CN207467094U" discloses a disc-type filling and sealing machine, including a frame and an electrical control box. A worktable is mounted on the frame, and a working disc is mounted on the worktable. The working disc is driven to rotate by a motor located below the worktable. A plurality of cup-receiving holes are evenly distributed around the axis of the working disc. The worktable is arranged in sequence around the axis of the working disc as follows: a cup-dropping station, a cup-detecting station, a filling station, a powder pressing and suction station, a film-dispensing station, a film-detecting station, a heat-sealing station, and a cup-dispensing station. The cup-dropping station is equipped with a cup-dropping device; the cup-detecting station is equipped with a cup-detecting device; the filling station is equipped with a feeding device; the powder pressing and suction station is equipped with a powder pressing and suction device; the film-dispensing station is equipped with a film-dispensing device; the film-detecting station is equipped with a film-detecting device; the heat-sealing station is equipped with a heat-sealing device; and the cup-dispensing station is equipped with a cup-dispensing device and a chute. The chute is located on the side of the cup-dispensing device and extends outside the frame. However, the aforementioned filling and sealing machine still has the following drawbacks: First, at the cup-dropping station, a cup-dropping robot grips the capsule cup cylinder, removes the capsule cup from the storage cylinder, and places it on the cup-receiving hole on the disc. The cup-dropping robot needs to lift and lower to pull out the capsule cup, which is slow and cannot meet the needs of rapid capsule cup production. Furthermore, the cup-dropping robot is prone to scratching the capsule cup cylinder during gripping, causing damage to the capsule cup cylinder and affecting its appearance.

[0004] Secondly, when the powder pressing and suction station presses the material in the cup, it sucks up the powder from the upper edge of the cup. However, it cannot completely remove the material during suction, and the membrane cannot completely seal the cup cavity, resulting in a high defect rate for the sealing machine.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a rotary filling and sealing machine that provides stable and fast cup dropping, does not scratch the side wall of the capsule cup, and can effectively remove material from the edge of the capsule cup, so as to solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rotary filling and sealing machine, comprising a frame and a transfer plate rotatably cooperating with the frame. The frame is provided with a cup-dropping station for placing cups, a filling station for filling materials, a powder pressing and suction station for flattening materials and removing waste materials, a film-dropping station for placing films, a heat-sealing station for heat-sealing films onto capsule cups, and a cup-discharging station for discharging finished products around the axis of the transfer plate. The transfer plate is provided with several transfer components for carrying capsule cups. The cup-dropping station includes a cup-dropping frame installed on the frame, a cup storage cylinder for placing capsule cups, several sets of cup-dropping rotating shafts for dropping capsule cups, and a cup-dropping motor for driving the cup-dropping rotating shafts to rotate. The cup-dropping rotating shafts are spirally provided with cup-dropping grooves that can contact the edge of the capsule cups. The rotation of the cup-dropping rotating shafts causes the capsule cups to move along the axis of the cup storage cylinder.

[0008] By adopting the above technical solution: the capsule cup is placed in the cup storage cylinder, and the edge of the capsule cup passes through the cup dropping groove on the cup dropping shaft. The cup dropping motor drives the cup dropping shaft to rotate, which can move the capsule cup along the axis of the cup storage cylinder to the transfer component. Multiple capsule cups can be dropped at the same time, realizing the rapid dropping of the capsule cups. At the same time, only the edge of the capsule cup contacts the cup dropping shaft. During the dropping process, the side wall of the capsule cup will not contact the cup dropping shaft, effectively avoiding scratches during the dropping process.

[0009] The above-mentioned rotary filling and sealing machine can be further configured such that: the output end of the cup-dropping motor is provided with a drive gear shaft, the cup-dropping rotating shaft is provided with a cup-dropping gear shaft, the drive gear shaft and the driven gear shaft are linked by a transmission belt, and the cup-dropping frame is also provided with several support gear shafts for supporting the transmission belt.

[0010] By adopting the above technical solution: the support gear shaft can adjust the tension of the rotating belt, so that the transmission belt and the drive gear shaft can be stably linked. When the drive motor is running, the rotation of the drive gear shaft causes the transmission belt to rotate circumferentially. The transmission belt drives the support gear shaft and the cup dropping gear shaft to rotate, so that the speed of the cup dropping shafts on both sides is consistent, so that the capsule cup can fall stably onto the transfer piece, ensuring the stability of the cup dropping station.

[0011] The aforementioned rotary filling and sealing machine can be further configured such that: a cup storage cylinder is also provided on the cup dropper, the cup storage cylinder has a cup inlet, one end of the cup storage cylinder is linked to the cup dropper and the other end is correspondingly set to the cup inlet, and the cup storage cylinder is also provided with an observation window for observing the amount of cups in the cup storage cylinder.

[0012] By adopting the above technical solution, the capsule cups can be placed in the storage cylinder, and the number of capsule cups in the storage cylinder can be observed through the observation window. When the number of capsule cups in the storage cylinder is insufficient, the capsule cups on the storage cylinder can be pushed into the storage cylinder from the inlet, thereby achieving rapid replenishment of capsule cups, reducing the downtime of the sealing machine, and improving the production efficiency of the sealing machine.

[0013] The aforementioned rotary filling and sealing machine can be further configured as follows: the cup dropping station and the cup discharging station are equipped with cup discharging detection devices for detecting whether the transfer component has discharging a cup; the frame is coaxially provided with a first cup-top shaft on the cup storage cylinder; the first cup-top shaft is slidably engaged with the frame; the frame is provided with a first cup-top cylinder for driving the first cup-top shaft to move axially back and forth; one end of the first cup-top shaft is provided with a first cup-top block; and the other end is linked to the output end of the first cup-top cylinder.

[0014] By adopting the above technical solution: when the cup dispensing station fails to dispense material, it will block the transfer component, preventing the next capsule cup from falling into the transfer component, which will affect subsequent production. When the cup dispensing detection device detects that there is a capsule cup left in the transfer component and moves to the cup dropping station, the first cup-top cylinder pushes the first positioning shaft to move so that the first cup-top block enters the transfer component, pushing out the remaining capsule cup in the transfer component. Then the cup dropping station operates to drop the new capsule cup into the transfer component for the next filling and sealing production.

[0015] The aforementioned rotary filling and sealing machine can be further configured as follows: the powder pressing and suction station includes a powder pressing mounting frame, a powder pressing bracket that slides with the powder pressing mounting frame, and a powder pressing shaft on the powder pressing bracket. The powder pressing mounting frame is equipped with a powder pressing cylinder. The powder pressing bracket is linked to the output end of the powder pressing cylinder. The powder pressing shaft is rotatably connected to the powder pressing bracket. One end of the powder pressing shaft is equipped with a powder pressing driven wheel, and the other end is equipped with a powder pressing cover for pressing the material in the capsule cup. The powder pressing bracket is equipped with a powder pressing rotary cylinder. The output end of the powder pressing rotary cylinder is linked to a powder pressing drive wheel. The powder pressing drive wheel is linked to the powder pressing driven wheel. The powder pressing shaft is fitted with a powder suction cylinder. Several powder suction pipes are inserted through the end face of the powder pressing shaft near the powder pressing cover. The powder suction pipes are connected to the powder suction cylinder. The powder suction cylinder is also equipped with a suction pipe.

[0016] By adopting the above technical solution: the powder pressing cylinder pushes the powder pressing bracket to move, so that the powder pressing cover at the end of the powder pressing shaft is pressed into the capsule cup in the transfer component, and the filled capsule cup is compacted. During the compaction process, the powder pressing rotary cylinder drives the powder pressing drive wheel to rotate, and the powder pressing drive wheel drives the powder pressing driven wheel to rotate, thereby causing the powder pressing shaft to rotate circumferentially. At the same time, the suction pipe provides suction force, so that the suction pipe rotates along the edge of the capsule cup to suck up the material that falls on the edge of the cup, thereby completely removing the material on the edge of the capsule cup. The cleaning efficiency is high, and it is easy for the membrane to be completely heat-sealed on the cup mouth.

[0017] The aforementioned rotary filling and sealing machine can be further configured as follows: the film feeding station includes a film feeding frame, a film material rack for placing film material, several film feeding slide bars on the film feeding frame, a film feeding slider that slides with the film feeding slide bars, a film feeding rotating shaft that rotates with the film feeding slider, a film suction nozzle on the film feeding rotating shaft, and a film feeding assembly for linkage with the film feeding rotating shaft. The film feeding frame has a film feeding cylinder. The film feeding slider is linked with the output end of the film feeding cylinder to cause the film feeding slider to reciprocate along the axis of the slide bar. The film feeding assembly is used to drive the film feeding rotating shaft to rotate circumferentially when the film feeding slider moves, causing the film on the film suction nozzle to rotate onto the capsule cup.

[0018] By adopting the above technical solution: the film is placed in the film rack, and the suction nozzle is located below the film rack. After the suction nozzle adsorbs a film, the film placement cylinder pushes the film placement module to move along the film placement slide axis to the side of the transfer tray. During the movement, the film placement assembly rotates the film placement shaft so that the film is placed on the transfer component. Then the suction nozzle stops adsorbing the film, completing one film adsorption and placement operation. Then the adjusting cylinder is reset, and the adjusting assembly rotates the film placement shaft synchronously, so that the end of the suction nozzle is again located below the film rack, and the next film placement operation is performed.

[0019] The aforementioned rotary filling and sealing machine can be further configured as follows: the film feeding assembly includes a steering block mounted on the film feeding shaft; the film feeding frame is provided with a film feeding groove; the film feeding shaft is slidably engaged with the film feeding groove; the steering block includes a positioning groove, a first rotating groove, a second rotating groove, and a guide groove; the film feeding frame is provided with a positioning rod slidably engaged with the positioning groove, a first rotating rod slidably engaged with the first rotating groove, a second rotating rod slidably engaged with the second rotating groove, and a guide rod slidably engaged with the guide groove; the film feeding cylinder pushes the film feeding block to move axially, causing the steering block to disengage from the positioning rod and gradually engage with the first rotating rod, the guide rod, and the second rotating rod to cause the steering block to rotate.

[0020] By adopting the above technical solution: the positioning rods are located at both ends of the film-laying chute, the first rotating rod, the guide rod, and the second rotating rod are located on the side of the film-laying chute. When the film-laying shaft is in the initial position of the film-laying frame, the positioning rod is located in the positioning groove of the steering block. During the process of the film-laying cylinder pushing the film-laying block to move, the film-laying shaft slides in the film-laying chute. The steering block first disengages from the positioning groove, and then the first rotating rod gradually engages in the first rotating groove, causing the film-laying shaft to rotate initially. Then the guide rod engages in the guide groove, causing the first rotating rod to disengage from the first rotating groove. The second rotating rod engages in the second rotating groove, causing the steering block to rotate 180°, realizing the automatic rotation of the film-laying shaft. When the steering block moves to the bottom of the positioning groove, the positioning groove and the positioning rod re-engage, improving the stability of film-laying. After film-laying is completed, the steering block rotates again, causing the film-laying shaft to return to its initial state.

[0021] The aforementioned rotary filling and sealing machine can be further configured as follows: the heat sealing station includes a heat sealing frame, a heat sealing plate rotatably connected to the heat sealing frame, a heat sealing cylinder mounted on the heat sealing frame, a heat sealing shaft linked to the output end of the heat sealing cylinder, a heat sealing sleeve slidably engaged with the heat sealing shaft, a heat sealing plate slidably engaged with the heat sealing sleeve, and a heat sealing block for heat sealing the film. The heat sealing plate has a sliding groove that slidably engages with the heat sealing frame. The heat sealing block is located at one end of the heat sealing plate opposite to the heat sealing cylinder. The heat sealing shaft has a receiving cylinder with a first limit. The heat sealing sleeve has a first sliding hole and a second limiting hole on its side wall, and the heat sealing plate has a second sliding hole on its side wall. The first limiting hole and the first sliding hole are slidably engaged, and the second limiting hole and the second sliding hole are slidably engaged. The receiving cylinder has a number of heat sealing elastic elements. One end of the heat sealing elastic element abuts against the end face of the receiving cylinder, and the other end abuts against the end face of the heat sealing plate. The end face of the heat sealing plate is also provided with a limiting element, which is installed on the heat sealing plate through a limiting sleeve. The heat sealing frame is also provided with a support block, and the support block is provided with a support wheel, which can contact the end face of the transfer tray.

[0022] By adopting the above technical solution: the heat-sealing cylinder moving part heat-sealing block presses against the capsule cup on the transfer part to heat-seal and fix the diaphragm. When the heat-sealing block contacts the capsule cup, the heat-sealing sleeve and heat-sealing plate slide within the receiving cylinder. The heat-sealing elastic element maintains the heat-sealing pressure and the pressure of the diaphragm on the capsule cup, so that the diaphragm is evenly heat-sealed on the capsule cup. At the same time, during heat sealing, the support wheel can abut against the end face of the transfer tray to maintain the stability of the transfer tray during heat sealing. In addition, when it is necessary to clean the heat sealing station, the heat-sealing plate can be rotated to disengage the sliding groove from the heat-sealing frame, change the position of the heat sealing station, and improve the convenience of cleaning the heat sealing station.

[0023] The aforementioned rotary filling and sealing machine can be further configured as follows: the cup dispensing station includes a cup dispensing frame, a cup dispensing assembly mounted on the cup dispensing frame, a cup dispensing motor for driving the cup dispensing assembly, a second cup dispensing shaft for ejecting material, a second cup dispensing block mounted on the second cup dispensing shaft, and a second cup dispensing cylinder for driving the second cup dispensing shaft to reciprocate axially. The cup dispensing assembly has a cup dispensing plate at one end near the transfer plate, the cup dispensing frame has a cup pushing cylinder, the output end of the cup pushing cylinder has a cup pushing plate, the cup pushing plate is slidably engaged with the cup dispensing plate, the cup pushing plate has a receiving groove for accommodating capsule cups, the second cup dispensing cylinder pushes the second cup dispensing shaft to move along the axis to cause the second cup dispensing block to eject the capsule cup in the transfer component to the cup dispensing plate, and the cup pushing cylinder pushes the cup pushing plate to move the capsule cup located on the cup dispensing plate to the cup dispensing assembly.

[0024] By adopting the above technical solution: after the capsule cup is heat-sealed, the transfer tray rotates the capsule cup to the discharge station. The second top cup cylinder pushes the second top cup shaft to move, and the second top cup block pushes the capsule cup out of the rotating part. At the same time, the push cup cylinder pushes the push cup plate, and then retracts to abut the receiving groove against the side wall of the capsule cup, thereby driving the capsule cup to the cup discharge assembly to complete the discharge.

[0025] The aforementioned rotary filling and sealing machine can be further configured as follows: the cup dispensing assembly includes a mounting frame, cup dispensing rollers hinged to both ends of the mounting frame, and a cup dispensing conveyor belt linked to the cup dispensing rollers. The mounting frame is provided with a connecting groove, and the side of the cup dispensing conveyor belt is provided with a baffle plate, which slides in conjunction with the connecting groove.

[0026] By adopting the above technical solution: the cup-discharging motor drives the discharge roller to rotate, which in turn drives the cup-discharging conveyor belt to rotate, thus discharging the capsule cup. At the same time, the side of the mounting frame slides and engages with a baffle plate to limit the position of the capsule cup, ensuring that the capsule cup is always on the cup-discharging conveyor belt, thereby achieving stable discharging of the capsule cup.

[0027] The beneficial effects of this utility model are as follows: First, the cup dropping station can accommodate the edge of the capsule cup through the cup dropping groove on the cup dropping shaft. When the cup dropping shaft rotates, it will drive the capsule cup to move along the axis of the storage cylinder, realizing the rapid dropping of the capsule cup. Compared with the traditional method of using a robotic arm, the cup dropping efficiency of the cup dropping shaft is faster. At the same time, it will not rub against the side wall of the capsule cup during the dropping process, improving the integrity of the capsule cup.

[0028] Secondly, the rotary pressing station ensures that the material is pressed flat. At the same time, the powder suction rod and the suction shaft rotate synchronously. The powder suction rod continuously sucks up the powder from the edge of the capsule cup, removing the material that falls on the edge of the capsule cup, providing a foundation for subsequent membrane placement and heat sealing, and ensuring the sealing of the membrane.

[0044] like Figure 10 The cup dispensing station 8 shown includes a cup dispensing frame 81, a cup dispensing assembly 82 mounted on the cup dispensing frame 81, a cup dispensing motor 83 that drives the cup dispensing assembly 82, a second cup dispensing shaft 84 for ejecting material, a second cup dispensing block 85 mounted on the second cup dispensing shaft 84, and a second cup dispensing cylinder 86 for driving the second cup dispensing shaft 84 to move axially back and forth. The cup dispensing assembly 82 has a cup dispensing plate 87 at one end near the transfer plate 2. The cup dispensing frame 81 has a cup pushing cylinder 811. The output end of the cup pushing cylinder 811 has a cup pushing plate 812. The cup pushing plate 812 is slidably engaged with the cup dispensing plate 87. The cup pushing plate 812 has a receiving groove 813 for accommodating capsule cups. The second cup dispensing cylinder 86 pushes the second cup dispensing shaft 84 to move along the axis, causing the second cup dispensing block 85 to eject the capsule cup in the transfer member 21 onto the cup dispensing plate 87. The cup pushing cylinder 811 pushes the cup pushing plate 812 to move the capsule cup located on the cup dispensing plate 87 onto the cup dispensing assembly 82.

[0045] The cup dispensing assembly 82 includes a mounting frame 821, a cup dispensing roller shaft 822 hinged to both ends of the mounting frame 821, and a cup dispensing conveyor belt 823 linked with the cup dispensing roller shaft 822. The mounting frame 821 has a connecting groove 824, and the side of the cup dispensing conveyor belt 823 has a baffle plate 825, which slides in cooperation with the connecting groove 824.

[0046] The cup dropping station 3 and the cup discharging station 8 are equipped with a cup discharging detection station 36 for detecting whether the transfer component has discharged a cup. The frame 1 is coaxially provided with a first cup-top shaft 37 on the cup storage cylinder 32. One end of the first cup-top shaft 37 is provided with a first cup-top block 38 and the other end is linked to a first cup-top cylinder 39. When the cup discharging detection station 36 detects that there is a capsule cup remaining in the transfer component 21, the first cup-top cylinder 39 operates to push the first cup-top shaft 37 to move, and the first cup-top block 38 presses against the bottom of the capsule cup to cause the remaining capsule cup to detach from the transfer component 21.

[0047] The working principle of this embodiment is as follows: the cup dropping motor 34 drives the cup dropping shaft 33 to rotate, dropping the capsule cup into the transfer component 21 on the transfer tray 2. Then the drive component 22 drives the transfer tray 2 to rotate. When passing the cup dropping detection station 47, the cup dropping detection station 47 detects that there is a capsule cup in the transfer component 21. The transfer tray 2 continues to rotate to the filling station 4.

[0048] The feeding motor 44 rotates the stirring shaft 45, and the first stirring rod 451 and the second stirring rod 452 gather the material at the edge of the hopper 42 toward the discharge pipe 43. The discharge screw 46 continuously conveys the material into the discharge pipe 43, and the material is filled into the capsule cup on the transfer component 21 through the discharge pipe 43.

[0049] Then, the transfer tray 2 transfers the capsule cup to the powder pressing and suction station 5. The powder pressing cylinder 55 pushes the powder pressing bracket 52 down, so that the powder pressing cover 54 is pressed into the capsule cup. Then, the powder pressing rotary cylinder 56 operates, driving the powder pressing shaft 53 to rotate. While the material is being rotated and flattened, the suction pipe 534 starts to suck air. The suction pipe 533 sucks up the material that falls on the edge of the cup. After the powder pressing and suction is completed, the powder pressing and suction station 5 is reset.

[0050] Then, the transfer tray 2 transfers the capsule cup to the film placement station 6. The suction nozzle 651 picks up a film sheet from the film rack 62. Then, the film placement cylinder 611 pushes the film placement slider 64 down. During the movement, the steering block 661 rotates the film placement shaft 65 through the first rotating groove 663, the guide groove 665, and the second rotating groove 664. At this time, the film placement slider 64 moves to the bottom of the film placement groove 612 on the film placement rack 61. The suction nozzle 651 stops picking up the film sheet, and the film sheet is naturally placed on the capsule cup. After placement, the film placement station 6 is reset.

[0051] Afterwards, the capsule cup passes through the membrane inspection station to check whether there is a membrane on the capsule cup. If a membrane is detected, the transfer tray 2 continues to rotate, transferring the capsule cup to the heat sealing station 7.

[0052] The heat-sealing cylinder 73 pushes the heat-sealing shaft 74 to press the heat-sealing block 77 onto the edge of the capsule cup, heat-sealing the membrane onto the capsule cup to seal the capsule cup. After the heat-sealing is completed, the heat-sealing station 7 is reset, and then the transfer tray 2 transfers the sealed capsule cup to the cup-out station 8.

[0053] The pusher cylinder 811 pushes the pusher plate 812, so that the pusher groove is located at the edge of the transfer component 21. Then, the second top cup cylinder 86 pushes the second top cup shaft 84, and the second top cup block 85 pushes out the heat-sealed capsule cup in the transfer component 21. At the same time, the pusher cylinder 811 retracts, and the receiving groove 813 fits against the side wall of the capsule cup, so that the capsule cup passes through the cup exit plate 87 and enters the cup exit assembly 82. The cup exit motor 83 drives the cup exit roller shaft 822 to rotate, which drives the discharge transmission belt 823 to rotate, so as to transfer and collect the capsule cup and complete the capsule cup filling and sealing.

[0054] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
