Description

Technical Field

[0001] This utility model relates to the field of cup packaging equipment, and more particularly to an automated film packaging device for stacking cups and bowls. Background Technology

[0002] Existing cup packaging equipment generally employs a top-feeding film, utilizing the cup's own weight for descent, and side sealing / horizontal cutting. For example, Chinese utility model patent CN205034412U discloses a paper cup packaging machine, including a cup conveyor platform. The discharge end of the conveyor platform has a sealing and cutting station with an L-shaped sealing and cutting device for L-shaped sealing and cutting of the packaging film. Above the L-shaped sealing and cutting device is a film feeding mechanism, the width direction of which is parallel to the cup feeding direction, which is the cup height direction. At the sealing and cutting station, a film-supporting rod is located above the cutter of the L-shaped sealing and cutting device to expand the packaging film and allow the cup to be fed in. When the cup is fed in, the cup height direction is the same as the width direction of the conveying film, and an L-shaped sealing and cutting device is used. The specific packaging process is as follows: The double-layered folded packaging film delivered by the film feeding mechanism is opened by the film support rod above the cutter of the L-shaped sealing and cutting device (at this time, the L-shaped sealing and cutting device is in a closed state). In the width direction, the front side of the packaging film facing the cup conveyor platform is opened by the film support rod to form an opening for the cup to be fed in, while the rear side is closed. After the first sealing and cutting, the bottom edge of the packaging film is also closed. At this time, the cup is fed into the middle of the double-layered packaging film through the cup conveyor platform from the opening, and the bottom of the cup is supported by the L-shaped sealing and cutting device. Then, the L-shaped sealing and cutting device opens, and the film feeding mechanism feeds the film. Under the weight of the cup, the cup falls to the appropriate position below the cutter. Immediately afterwards, the L-shaped sealing and cutting device closes again, and the cutter performs an L-shaped seal cut on the packaging film. The packaging film above the cup is heat-sealed and cut, forming the closed line at the bottom edge of the packaging film for the next packaging. Simultaneously, the packaging film on the front side of the cup is also heat-sealed and cut. The cut waste edge is wound up by the waste material winding device, completing the packaging of one cup. This cycle is repeated to achieve automated paper cup packaging production. However, the following problems exist in actual production: 1. The cup's center of gravity often leans towards the rim. During the fall, the cup tilts, further causing the film to misalign, resulting in at least one of the longitudinal or transverse seals being misaligned. 2. The bottom of the film bears the weight of the cup. When sealing above the cup, the upper sealing plate clamps the packaging film, causing it to be pulled outwards along the outer wall of the cup, leading to deformation or breakage, especially in the bottom sealing area. 3. The film is thin and lightweight. Before the horizontal sealing is cut, the bottom of the film is in a free hanging state, which is easily affected by the airflow in the workshop and the wind interference generated by the movement of the sealing plate cutter, resulting in the side sealing and horizontal sealing lines being skewed. Therefore, there is an urgent need for a device that can quickly and accurately complete the sealing and cutting before horizontal sealing without increasing the film allowance, so that the packaging film is more neat and beautiful and the yield is higher. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing an automated film packaging device for stacking cups and bowls.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution: An automated film packaging device for stacking cups and bowls includes a film feeding mechanism, a film cutting and sealing mechanism, and a supporting surface for supporting cups above the film cutting and sealing mechanism. A film-supporting mechanism is provided on the film conveying path output by the film feeding mechanism to expand the continuously conveyed packaging film, forming a channel for cups to enter between the expanded packaging films. The side of the channel has a cup inlet. The film cutting and sealing mechanism includes a sealing plate cutter for sealing and cutting the packaging film. The packaging film passes between the sealing plate cutter. The sealing plate cutter has a power source to drive it to close or separate. The sealing portion of the sealing plate cutter corresponds to at least... The packaging film features a longitudinal seal on the side of the cup inlet and a transverse seal on the top of the cup. The cutting position of the sealing plate cutter corresponds at least to the transverse seal area on the top of the cup. A film pressing mechanism is installed below the bracket. This mechanism includes a pressing component connected to a power source. The air outlet of the pressing component is located above the sealing plate cutter at least when the sealing plate cutter is closed. As the film supply mechanism feeds the packaging film downwards, the cup falls from the supporting surface. Simultaneously, the pressing component applies a downward force to the inner side of the sealing portion below the packaging film via the power source to level the film. During sealing, the film pressing mechanism applies downward force to the inner side of the film, flattening the bottom sealing area. The method of applying force is not limited, preventing lateral film deviation due to differences in shape and weight on both sides after the cups are stacked, and reducing film offset caused by airflow. This maintains the horizontal levelness of the transverse seal on the top of the packaging film after subsequent L-shaped transverse and longitudinal sealing. Since the horizontal seal on the top of each cut packaging film is the horizontal seal on the bottom of the next packaging film, ensuring that the horizontal seal on the top is horizontal means ensuring that the sealing positions on the top and bottom sides of each packaging film are horizontal and parallel to the central axis of the cup.

[0005] Preferably, the system also includes a bracket for supporting the cup entering from the cup inlet. The cup inlet is located at the input end of the bracket, which extends into the channel and is positioned above the film-sealing mechanism. The bracket can be moved to either support the cup or release the cup. When the bracket is supporting the cup, it forms a supporting surface; or when the sealing plate cutter closes, its upper surface mates to form a supporting surface for supporting the cup. The cup falls onto the supporting surface by rotating or separating the bracket. The supporting surface supports the cup, which falls directly to the bottom of the packaging film. This method results in a shorter drop height, reducing the impact of the cup on the bottom of the packaging film. Alternatively, the supporting surface can be formed directly on the upper surface of the sealing plate cutter, but this requires a bracket transfer after the cup is fed in, or the bracket can act as a supporting surface, allowing the cup to detach directly from the rotating or separating bracket and fall to the bottom of the packaging film. The bracket can consist of at least two support rods, with the bottom of the cup housed in the cavity between the support rods. The separation method is to move the support rods apart so that the cup falls. The bracket can also be an arc-shaped plate or a semi-cylindrical shape, without limitation, as long as it can support the cylindrical cup.

[0006] Preferably, the film pressing mechanism is an air blowing mechanism, which includes a downward-facing air nozzle that blows air onto the inner side of the sealing portion below the film. The air nozzle is always positioned above the sealing plate cutter. This structure is relatively simple, and the air blowing mechanism does not need to directly contact the film, thus avoiding damage to the film. Furthermore, this type of film pressing mechanism eliminates reciprocating motion, making control simpler.

[0007] Preferably, the film pressing mechanism is a film pulling mechanism, which includes a pressing component connected to a power source that drives its lifting and lowering movement. The pressing component extends into the channel and acts on the inner side of the sealing portion below the packaging film. As the cup falls from the supporting surface, the pressing component moves downwards, pulling down the sealing portion of the packaging film. The pressing component leaves the sealing portion of the sealing plate cutter before the sealing plate cutter of the film cutting and sealing mechanism closes. The pressing component's contact with the film during the downward pulling process makes the film more stable after being pulled down, ensuring that the bottom sealing portion is horizontal.

[0008] Preferably, the pressing component rises above the sealing plate cutter within the channel before the sealing plate cutter of the film-cutting and sealing mechanism closes. The pressing component is connected to a servo motor, and the film supply mechanism is connected to a servo motor that drives its rotation. The two operate synchronously, ensuring that the pressing component maintains synchronous contact with the inner side of the bottom seal of the packaging film during its descent. The pressing component stops simultaneously with the servo motor of the film supply mechanism and returns to its original position. The use of a servo motor to drive the pressing component and the film supply servo synchronously ensures that the film is accurately pulled down by the pressing component, avoiding damage to the film. When the film is fed from above, the film-pulling plate pulls down; when the film stops at the top, the film-pulling plate immediately rises back to its original position, guaranteeing that the film is accurately pulled down by the pressing component and avoiding damage to the film.

[0009] Preferably, the film-stretching mechanism includes a film-stretching plate, a lead screw, and a motor mounting base. The servo motor is mounted on the motor mounting base and is connected to the lead screw bolt via a nut. The servo motor drives the nut to rotate, thereby driving the lead screw to rise and fall. The film-stretching plate is fixedly installed with the lead screw, and the pressing component is vertically arranged on the film-stretching plate. The pressing component is rod-shaped.

[0010] Preferably, a film clamping mechanism is also included. This mechanism comprises clamping plates located on both sides of the packaging film, below the sealing cutter. The clamping plates are connected to a power source that drives them to close and open. The clamping plates clamp the sides or bottom of the packaging film before the sealing cutter closes. Clamping the sides or bottom of the film before sealing further prevents the film from deviating due to airflow generated by the closing action of the sealing cutter or the airflow within the production space itself during sealing. This further ensures the parallelism of the top sealing and cutting with the cup body axis, avoiding or reducing side sealing misalignment.

[0011] Preferably, the system also includes a film clamping mechanism, comprising clamping plates located on both sides of the packaging film, positioned below the sealing cutter. The clamping plates are connected to a power source that drives them to close and open. Before the sealing cutter closes, the clamping plates clamp the sides or bottom of the packaging film. When open, the clamping plates provide space for the lowering component to descend and ascend. After the lowering component presses and shapes the packaging film, the clamping plates clamp the film in a horizontal position at the bottom, ensuring the straightness of the sealing and cutting.

[0012] Preferably, a cup-supporting mechanism is also included. When the cup falls from the supporting surface, the cup-supporting mechanism is located below the film-cutting and sealing mechanism to support the falling cup. After the cup falls into the film bag, the support rod slightly supports the bottom of the cup, and the weight of the cup is borne by the support rod, so that the bottom of the packaging film remains stretched before sealing, thus preventing the bottom from being squeezed and cracked when the sealing plate cutter clamps the film.

[0013] Preferably, the cup-supporting mechanism is located on the side away from the cup inlet. The cup-supporting mechanism is connected to a rotary cylinder that drives its rotation. The cup-supporting mechanism includes at least two parallel support rods. Rotation causes the cup to move away from the cup-supporting mechanism. The rotary cylinder is mounted on a position-adjustable movable mounting block. The cup-supporting mechanism switches between horizontal and vertical states by rotation, used to support or lower the cup.

[0014] This utility model, by adopting the above technical solution, has significant technical effects: 1. The membrane pressing mechanism counteracts airflow disturbances, ensuring alignment of the longitudinal and transverse seal positions; 2. The rotating cup support mechanism lifts the bottom of the cup body to prevent the protective plate from breaking under stress when clamping the film. The film clamping mechanism fixes the film edge after pulling the film back into place, thus solving the problem of film displacement caused by the weight imbalance of the cup body. 3. The servo system synchronously controls the film feeding, film pulling, and return actions, ensuring the automation of the entire process and high work efficiency, enabling uninterrupted operation.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] Example 1 An automated film packaging device for stacking cups and bowls, such as Figure 1-3As shown, the package includes a film supply mechanism 12, a film cutting and sealing mechanism 11, and a supporting surface for supporting the cup body above the film cutting and sealing mechanism 11. A film-supporting mechanism is provided on the film conveying path output by the film supply mechanism 12 to expand the continuously conveyed packaging film, forming a channel 13 between the expanded packaging films for the cup body to enter. The side of the channel 13 has a cup body inlet. The film cutting and sealing mechanism 11 includes a sealing plate cutter 111 for sealing and cutting the packaging film. The packaging film passes between the sealing plate cutters 111, and the sealing plate cutter 111 has a power source to drive it to close or separate. The sealing portion of the sealing plate cutter 111 is at least... The sealing film should be longitudinally sealed on the side of the cup inlet and transversely sealed on the top of the cup. The cutting position of the sealing plate cutter 111 should at least correspond to the transverse sealing part above the cup of the packaging film. A film pressing mechanism is provided below the bracket 14. The film pressing mechanism includes a pressing component connected to a power source. The air outlet of the pressing component is located above the sealing plate cutter 111 at least when the sealing plate cutter 111 is closed. The film supply mechanism provides the packaging film downward while the cup falls from the supporting surface. While the film supply mechanism conveys the packaging film downward, the pressing component applies a downward force to the inner side of the sealing part below the packaging film through the power source to level the film. The driving power source of the sealing plate cutter 111 can be a cylinder, electric cylinder, motor, or a transmission mechanism such as a linkage, swing arm, lead screw, or synchronous wheel. The sealing plate cutter 111 usually adopts a heat sealing method in this field. This method is a conventional technical means in the field of plastic packaging and will not be described in detail here.

[0019] like Figure 4 As shown, it also includes a bracket 14 for carrying the cup body entering from the cup body inlet. The cup body inlet is located at the input end of the bracket 14. The bracket 14 extends into the channel 13 and is located above the film cutting and sealing mechanism 11. The bracket 14 can be in a state of supporting the cup body and a state of releasing the cup body by moving. When the bracket 14 is in the state of supporting the cup body, it forms a supporting surface. When the sealing plate cutter 111 closes in opposite directions, the upper surface cooperates to form a supporting surface for supporting the cup body. The cup body on the bracket 14 falls onto the supporting surface by rotating or separating from each other.

[0020] As one embodiment, which is not shown in the drawings, the film pressing mechanism is an air blowing mechanism, which includes a downward-facing air nozzle that blows air onto the inside of the sealing portion below the film. The air nozzle is always positioned above the sealing plate cutter 111.

[0021] The film pressing mechanism is a film pulling mechanism 15. The film pulling mechanism 15 includes a pressing component 151. The pressing component 151 is connected to a power source that drives its lifting and lowering movement. The pressing component 151 extends into the channel 13. The pressing component 151 acts on the inner side of the sealing part below the packaging film. When the cup falls from the supporting surface, the pressing component 151 moves downward to pull down the sealing part of the packaging film. The pressing component 151 leaves the sealing part of the sealing plate cutter 111 before the sealing plate cutter 111 of the film cutting and sealing mechanism 11 closes.

[0022] Before the sealing plate cutter 111 of the film cutting and sealing mechanism 11 closes, the pressing component 151 rises to the inside of the channel 13 above the sealing plate cutter 111. The pressing component 151 is connected to a servo motor 152, and the film supply mechanism is connected to a servo motor that drives it to rotate. The two operate synchronously so that the pressing component 151 keeps in synchronous contact with the inner side of the bottom seal of the packaging film when it descends. The pressing component 151 stops and returns to its original position when the servo motor 152 of the film supply mechanism stops.

[0023] like Figure 2 As shown, the film stretching mechanism 15 includes a film stretching plate 153, a lead screw 154, and a motor mounting base 155. A servo motor 152 is mounted on the motor mounting base 155 and is bolted to the lead screw 154 via a nut 156. The servo motor 152 drives the nut 156 to rotate, thereby driving the lead screw 154 to rise and fall. The film stretching plate 153 is fixedly installed on the lead screw 154. The pressing component 151 is vertically arranged on the film stretching plate 153 and is rod-shaped.

[0024] like Figure 5 As shown, it also includes a film clamping mechanism, which includes clamping plates 16 located on both sides of the packaging film. The clamping plates 16 are located below the sealing plate cutter 111. The clamping plates 16 are connected to a clamping plate power source 161 that drives them to close and open. The clamping plates 16 clamp the sides or bottom of the packaging film before the sealing plate cutter 111 closes.

[0025] It also includes a film clamping mechanism, which includes clamping plates 16 located on both sides of the packaging film. The clamping plates 16 are located below the sealing plate cutter 111. The clamping plates 16 are connected to a clamping plate power source 161 that drives them to close and open. The clamping plates 16 clamp the sides or bottom of the packaging film before the sealing plate cutter 111 closes. When the clamping plates 16 are open, they have space for the pressing component 151 to descend and pass through.

[0026] like Figure 6 As shown, it also includes a cup-supporting mechanism 17. When the cup falls from the supporting surface, the cup-supporting mechanism 17 is located below the film-cutting and sealing mechanism 11 and is used to support the falling cup.

[0027] The cup-holding mechanism 17 is located on the side away from the cup body inlet. The cup-holding mechanism 17 is connected to a rotary cylinder 171 that drives it to rotate. The cup-holding mechanism 17 includes at least two parallel support rods. The cup body is moved away from the cup-holding mechanism 17 by rotating. The rotary cylinder 171 is mounted on a position-adjustable movable mounting block 172.

[0028] One implementation method's workflow: a. The sealing plate cutter 111 separates from each other, the film pulling mechanism returns to its original position, the film supply servo motor starts, and continues to convey the packaging film material downward. After the previous cup falls, the sealing plate cutter 111 closes and seals and cuts. Then, the cups stacked into a cylinder enter the channel 13 between the packaging films through the inlet and are supported by the bracket 14. The cups can enter by mechanical pushing, gravity sliding, or support and movement transfer, which is not limited here. b. The cup body is released when the bracket rotates or the bracket rods separate from each other and fall onto the upper surface of the sealing plate cutter 111, which is closed due to the cutting of the previous packaging film. c. After the previous packaging film is sealed and cut, the sealing plate cutter 111 separates from each other and releases the cup body under the drive of the power source. The film servo motor starts and synchronously conveys the packaging film material downward with the cup body. The film pulling servo motor of the film pulling mechanism starts synchronously and pulls down and flattens the bottom that has been sealed below the film. When the cup body reaches the bottom, the cup supporting mechanism 17 slightly supports the bottom of the cup. Film pulling stage: synchronously pull down the packaging film. d. After the cup-supporting mechanism 17 supports the bottom of the cup, the clamping plate power source 161 drives the clamping plate 16 to clamp the side or bottom of the packaging film, so that the packaging film is flat before sealing. The sealing plate cutter 111 closes and cuts under the drive of the power source, and this cycle continues.
