Description

A fully automatic intelligent packaging machine Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a fully automatic intelligent packaging machine. Background Technology

[0002] Existing packaging machinery is widely used in pharmaceuticals, food, and daily necessities, capable of sealing plastic bags and boxes for fine granular, powdery, and liquid materials. However, when packaging and sealing metal materials such as screws and nuts, which are produced in large quantities, it's not enough to simply package and seal them; they must be packaged in specific quantities. Manually counting them one by one is labor-intensive and inefficient. Weighing them introduces errors, and even after the quantity is determined, the materials still need to be manually placed into plastic bags and sealed, resulting in a high workload and low efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a fully automatic intelligent packaging machine that accurately controls the packaging quantity and improves the pass rate through the combination of a vision sensor and a light source.

[0004] The technical solution of this utility model: A fully automatic intelligent packaging machine, including a frame, on which a material feeding mechanism, a film feeding mechanism, a film bag forming mechanism, a heat sealing mechanism, and a cutting mechanism are provided. The film bag forming mechanism includes a bag forming device that can roll the film into a cylindrical shape. The bag forming device has a channel inside. The material feeding mechanism includes a first vibrating hopper, a first vibrating track, and a second vibrating track. The first and second vibrating tracks are located below the first vibrating hopper and are used to collect the material falling from the first vibrating hopper. The first vibrating track has a first material channel that allows only one material to pass through at a time. The second vibrating track has multiple second material channels arranged side by side. Vibrators are provided below both vibrating tracks and below the first vibrating hopper. The vibrating hopper is equipped with a baffle and a first driving component that drives the baffle to slide to control the connection and disconnection between the first vibrating hopper and the second vibrating track. The frame is also equipped with a hopper, a qualified product discharge channel, and a non-qualified product discharge channel. The channel on the bag forming machine is connected to the qualified product discharge channel. The hopper is located below the discharge port of the two material channels. The qualified product discharge channel and the non-qualified product discharge channel are located on both sides of the hopper. The frame is also equipped with a light source, a vision sensor, and a control device. The light source, vision sensor, and vibrator are all connected to the control device. The light source is located above the hopper. The vision sensor is located below the vibrating track and is diagonally positioned opposite the light source. The light source is tilted and faces the vision sensor so that the vision sensor can capture the light from the light source.

[0005] Using the above technical solution, the material is fed by the material feeding mechanism and packaged by the material packaging module. The two material channels feed the materials separately and use light sources to provide sufficient illumination to ensure that the sensors can capture clear images. The vision sensor generates images or videos by capturing reflected or transmitted light to accurately determine the quantity of material entering the hopper. If the quantity is consistent with the set quantity, it enters the packaging belt from the qualified product discharge channel. If the quantity is different from the set quantity, it is retrieved from the unqualified product discharge channel and re-fed.

[0006] Further features of this invention: Two hoppers are provided, namely a first hopper and a second hopper. The first hopper is located above the second hopper. A qualified product discharge channel and a non-qualified product discharge channel are located on opposite sides of the second hopper. The first hopper has a storage chamber corresponding to the discharge port of the second material channel and a discharge channel corresponding to the discharge port of the first material channel. A first sliding plate and a second driving component that drives the first sliding plate to open or close the storage chamber are slidably provided on the first hopper. Second sliding plates and third driving components that drive the second sliding plates to control the connection and disconnection between the two hoppers and the discharge channel are slidably provided on opposite sides of the second hopper. Both the second and third driving components are connected to a control device.

[0007] By adopting the above further settings, the quantity of materials can be more accurately determined, thereby improving the packaging qualification rate.

[0008] A further feature of this invention is that a guide plate is provided on the frame at the discharge port of the two material channels. The guide plate is inclined and is hinged to the frame via a hinge shaft.

[0009] By adopting the above-mentioned further settings, the material in the material channel is guided into the hopper to prevent the material from falling out and affecting the packaging quantity.

[0010] A further feature of this invention includes a material feeding mechanism. The material feeding mechanism includes a frame, a second vibrating hopper, a feeding hopper, and a drive assembly for driving the feeding hopper to move up and down on the frame. The frame is located on one side of the machine frame. The second vibrating hopper is positioned lower than the first vibrating hopper. The feeding hopper is located between the second vibrating hopper and the machine frame, and may be located below the discharge port of the second vibrating hopper. The frame is provided with a third hopper and pressure rollers located on both sides of the third hopper. The feeding hopper moves upward and is pressed and tilted by the pressure rollers to pour the material in the feeding hopper into the third hopper.

[0011] With the above-mentioned further configuration, the material is introduced into the second vibrating hopper. After the second vibrating hopper vibrates, the material is fed into the feeding hopper. After the material has been fed for a period of time or has reached a certain quantity, the drive component works to move the feeding hopper upward. When it moves above the third hopper, the side of the feeding hopper contacts the pressure roller, and the feeding hopper continues to move upward. The feeding hopper will tilt under the action of the pressure roller, so that the material in the feeding hopper falls into the third hopper, and then into the first vibrating hopper, thus realizing the feeding of the material. This makes manual feeding more convenient, eliminates the need to climb, and is also safer.

[0012] A further feature of this invention is that the heat-sealing mechanism includes a longitudinal heat-sealing component and a transverse heat-sealing component, wherein the longitudinal heat-sealing component is disposed on the side of the bag forming machine, and the transverse heat-sealing component is disposed below the bag forming machine.

[0013] With the above-mentioned further configuration, the vertical heat-sealing assembly is used to heat-seal the film around the two sides of the back of the bag forming machine, and the horizontal heat-sealing assembly heat-seals the upper and lower bag openings to form an independent plastic film bag.

[0014] A further refinement of this invention: the longitudinal heat-sealing assembly includes two first heat-sealing blocks arranged opposite each other and a fourth driving member. The two first heat-sealing blocks are arranged vertically, and the fourth driving member is connected to one of the first heat-sealing blocks, which can drive it to slide closer to or away from the other first heat-sealing block. The transverse heat-sealing assembly includes two second heat-sealing blocks arranged opposite each other and a fifth driving member. Both second heat-sealing blocks are arranged horizontally, and the fifth driving member is connected to one of the second heat-sealing blocks, which can drive it to slide closer to or away from the other second heat-sealing block.

[0015] With a further modification, the longitudinal and transverse heat-sealing components have simple structures. Before longitudinal heat sealing, the two sides of the rolled-up cylindrical film are placed between the two first heat-sealing blocks. Then, the fourth driving component moves one of the first heat-sealing blocks closer to the other to facilitate film placement. The two first heat-sealing blocks always grip the film tightly to prevent the material from deforming it, while simultaneously performing longitudinal back heat sealing on the film bag. Before transverse heat sealing, the rolled-up film is placed between the two second heat-sealing blocks, and then driven by the fifth driving component... One of the second heat-sealing blocks slides closer to the other, and the two second heat-sealing blocks heat-seal the lower transverse opening of the film bag. After heat sealing, a certain amount of material is first put into the film bag. Then, the fifth driving component drives one of the second heat-sealing blocks to slide away from the other. When the upper opening of the film bag moves down between the two second heat-sealing blocks, the fifth driving component drives one of the second heat-sealing blocks to slide closer to the other, and performs a transverse heat-sealing operation on the upper opening of the film bag. This process is repeated to form an independent plastic film bag.

[0016] A further improvement of this invention is that the cutting mechanism includes a cutting blade and a sixth driving member. The cutting blade is installed in the middle of one of the second heat-sealing blocks, and the sixth driving member is connected to the cutting blade and can drive the cutting blade to slide closer to or further away from the other second heat-sealing block.

[0017] With the above-mentioned further configuration, a slot is opened in the middle of another second heat-sealing block. When the cutter slides, it can enter and exit the slot. After the horizontal heat-sealing component heat-seales the opening of the film bag, the cutter cuts off the heat-sealed opening of the film bag to complete the individual packaging.

[0018] A further feature of this invention is that the film feeding mechanism includes a feeding frame located above the bag forming device. The feeding frame is rotatably equipped with an active roller, a driven roller, a tensioning roller, and a transmission roller. A passage for film conveying is provided between the active roller and the driven roller. The tensioning roller is located below the active roller and can move in a direction close to or away from the active roller. The feeding frame is equipped with a motor that drives the active roller to rotate.

[0019] With the above-mentioned further configuration, the film passes through the passage between the active roller and the driven roller, and is wound around the tension roller, and then wound around the transmission roller to be conveyed to the bag forming unit. The motor drives the active roller to rotate, thereby driving the film transmission. The tension roller can ensure that the film is always in a tensioned state during transmission.

[0020] A further feature of this invention is that a material dropping platform is provided on the frame below the transverse heat sealing assembly, and a pushing component and a seventh driving component for driving the pushing component to slide laterally are provided on the rear side of the material dropping platform.

[0021] With the above-mentioned further configuration, the packaged materials fall onto the unloading platform and are pushed out by the pusher to complete the unloading of the finished products.

[0022] A further feature of this invention is that the frame is also provided with a pressure roller mechanism for driving film conveying. The pressure roller mechanism includes a first pressure roller group located between the longitudinal heat sealing assembly and the transverse heat sealing assembly. The first pressure roller group includes a first active pressure roller and a first driven pressure roller arranged opposite to each other. The first active pressure roller and the first driven pressure roller are rotatably mounted on the frame via a first rotating shaft A and a second rotating shaft B, respectively. An eighth driving member is provided on the frame to drive the first rotating shaft A to rotate.

[0023] With the above-mentioned further configuration, the first pressure roller rotates under the action of the eighth driving component, driving the film located between the two first pressure rollers downward to perform vertical heat sealing and horizontal heat sealing.

[0024] A further feature of this invention is that the pressure roller mechanism also includes a second pressure roller group located at the inlet of the longitudinal heat sealing assembly. The second pressure roller group includes a second active pressure roller and a second driven pressure roller arranged opposite to each other. The second active pressure roller and the second driven pressure roller are rotatably mounted on the frame via a second rotating shaft A and a second rotating shaft B. The second rotating shaft A and the first rotating shaft A rotate synchronously with each other via a transmission mechanism.

[0025] With the above-mentioned further configuration, a second pressure roller group is added. With the setting of the upper and lower pressure roller groups, the film can be clamped on the upper and lower sides of the longitudinal heat sealing component, thereby effectively preventing the soft film bag from being stretched and deformed downward due to the material it contains. In addition, the setting of the two pressure roller groups makes the film conveying effect better. When the first pressure roller group is working, the second pressure roller group is driven to work through the transmission mechanism. Attached Figure Description

[0046] As shown in Figure 1-15, a fully automatic intelligent packaging machine includes a frame 1. The frame 1 is equipped with a material feeding mechanism 2, a film feeding mechanism 3, a film bag forming mechanism, a heat sealing mechanism 4, and a cutting mechanism 51. The film bag forming mechanism includes a bag forming device that can roll the film into a cylindrical shape. The bag forming device has a channel inside. The bag forming device is not shown in the figure, and its structure is prior art. The material feeding mechanism 2 includes a first vibrating hopper 21, a first vibrating track 22, and a second vibrating track 23. The first and second vibrating tracks 22 and 23 are located below the first vibrating hopper 21 and are used to collect materials falling from the first vibrating hopper 21. The first vibrating track 22 has a channel for only one material to pass through at a time. The machine frame 1 is equipped with a material channel 221, multiple second material channels 231 arranged side by side on the second vibration track 23, and vibrators 24 below the two vibration tracks and the first vibration hopper 21. The first vibration hopper 21 is equipped with a baffle 211 and a first driving component 212 that drives the baffle 211 to slide and control the connection and disconnection between the first vibration hopper 21 and the second vibration track 23. The machine frame 1 is also equipped with a hopper, a qualified product discharge channel 7 and a non-qualified product discharge channel 8. The channel on the bag forming machine is connected to the qualified product discharge channel 7. The hopper is located below the discharge port of the two material channels. The qualified product discharge channel 7 and the non-qualified product discharge channel 8 are located on both sides of the hopper. The machine frame 1 is also equipped with a light source 9, a vision sensor 10 and a control device. The light source 9, vision sensor 10, and vibrator 24 are all connected to the control device. Each driving component in this application can be a cylinder, electric cylinder, motor, etc., and each driving component and motor are connected to the control device. The light source 9 is positioned above the hopper, and the vision sensor 10 is positioned below the vibration track and diagonally opposite to the light source 9. The light source 9 is tilted and faces the vision sensor 10 so that the vision sensor 10 can capture the light from the light source 9. The material feeding mechanism 2 feeds the material, and the material packaging module packages the material. Both material channels feed the material, and the light source 9 provides sufficient illumination to ensure that the sensor can capture a clear image. The vision sensor 10 generates an image by capturing reflected or transmitted light. Images or videos are used to accurately determine the quantity of material entering the hopper. If the quantity matches the set quantity, it enters the packaging belt through the qualified product discharge channel 7. If the quantity differs from the set quantity, it is retrieved through the unqualified product discharge channel 8 and reloaded. For example, the second material channel 231 in this application has 8 channels. If the quantity of packaged material is set to 85 pieces on the control device, after the vision sensor 10 detects that 81 pieces have been discharged, the vibrator 24 of the second vibration track 23 stops working, and the first drive member 212 drives the baffle 211 to slide and cut off the first vibration hopper 21 and the second vibration track 23. The first vibration track 22 continues to work, discharging the remaining 4 pieces of material in sequence. When the material falls into the hopper, it will be captured by the vision sensor 10.After the vision sensor 10 detects that the set quantity has been reached, the material enters the qualified product discharge channel 7 from the hopper for subsequent packaging. A blocking component can also be installed at the material discharge port of the material channel. This blocking component is driven by a cylinder to rise and fall, cutting off or connecting the material channel and the hopper. When the vision sensor 10 detects that the material quantity has reached the set quantity, the blocking component moves down to cut off the material channel and the hopper. Alternatively, this can be omitted, and the material can be cut off manually. A guide plate 20 is installed on the frame 1 at the discharge ports of the two material channels. The guide plate 20 is inclined and hinged to the frame via a hinge shaft to guide the material in the material channel into the hopper, preventing material from falling out and affecting the packaging quantity.

[0047] The hopper is provided with two hoppers, namely a first hopper 61 and a second hopper 62. The first hopper 61 is located above the second hopper 62. The qualified product discharge channel 7 and the unqualified product discharge channel 8 are respectively located on both sides of the second hopper 62. The first hopper 61 has a storage cavity 611 corresponding to the discharge port of the second material channel 231 and a discharge channel 612 corresponding to the discharge port of the first material channel 221. The first hopper 61 has a first sliding plate 613 and a second driving member 614 that drives the first sliding plate 613 to slide to open or close the storage cavity 611. The second hopper 62 has a second sliding plate 621 and a driving member 614 that drives the second sliding plate 621 to slide on both sides. The third drive component 622, which slides to control the connection and disconnection between the second hopper and the discharge channel, is connected to the control device. This allows for more accurate material quantity measurement and improved packaging qualification rate. If an error is detected in the quantity of material falling directly from the first material channel 221 into the second hopper 62, the material in the second hopper 62 can be directly discharged from the non-conforming product discharge channel 8. The material in the storage chamber 611 remains in the storage chamber 611, and the material in the first material channel 221 is re-discharged into the second hopper 62. Once the quantity is consistent, the material in the first hopper 61 falls into the second hopper 62, avoiding the need for large-scale material reloading.

[0048] It also includes a material feeding mechanism 80, which includes a base 801, a second vibrating hopper 802, a feeding hopper 803, and a drive assembly for driving the feeding hopper to move up and down on the base 801. The drive assembly can be a combination of a motor, gear set, and chain. The base 801 is located on one side of the frame 1. The second vibrating hopper 802 is set lower than the first vibrating hopper 21. The feeding hopper 803 is located between the second vibrating hopper 802 and the frame 1, and can be located below the discharge port of the second vibrating hopper 802. The base 801 is provided with a third hopper 804 and pressure rollers 805 located on both sides of the third hopper 804. The feeding hopper 803 moves upward through the pressure rollers 805. The material is tilted and pressed to pour the material in the feeding hopper 803 into the third hopper 804, and then introduced into the second vibrating hopper 802. After the second vibrating hopper 802 vibrates, the material is fed into the feeding hopper. After the material has been fed for a period of time or has reached a certain quantity, the drive component moves the feeding hopper upward. When it moves above the third hopper, the side of the feeding hopper contacts the pressing wheel, and the feeding hopper continues to move upward. The feeding hopper tilts under the action of the pressing wheel, so that the material in the feeding hopper falls into the third hopper. The frame is provided with through slots corresponding to the positions of the third hopper and the first vibrating hopper, so that the material falls into the first vibrating hopper, realizing the feeding of materials. This makes manual feeding more convenient, eliminates the need to climb, and is also safer.

[0049] The heat sealing mechanism 4 includes a longitudinal heat sealing component 41 and a transverse heat sealing component 42. The longitudinal heat sealing component 41 is disposed on the side of the bag forming machine, and the transverse heat sealing component 42 is disposed below the bag forming machine. The longitudinal heat sealing component is used to heat seal the film around the two sides of the rear side of the bag forming machine, and the transverse heat sealing component 42 heat seals the upper and lower bag openings to form an independent plastic film bag.

[0050] Specifically, the longitudinal heat-sealing assembly 41 includes two opposing first heat-sealing blocks 411 and a fourth driving member. The two first heat-sealing blocks 411 are arranged vertically, and the fourth driving member is connected to one of the first heat-sealing blocks 411, driving it to slide closer to or away from the other first heat-sealing block 411. The transverse heat-sealing assembly 42 includes two opposing second heat-sealing blocks 421 and a fifth driving member 422. Both second heat-sealing blocks 421 are arranged horizontally, and the fifth driving member 422 is connected to one of the second heat-sealing blocks 421, driving it to slide closer to or away from the other second heat-sealing block 421. The longitudinal heat-sealing assembly 41 and the transverse heat-sealing assembly 42 have simple structures. Before longitudinal heat sealing, the two sides of the rolled-up cylindrical film need to be placed between the two first heat-sealing blocks 411. Then, the fourth driving member drives one of the first heat-sealing blocks 411 and the other first heat-sealing block 411 closer together to facilitate the sealing of the film. During film placement, the two first heat-sealing blocks 411 always grip the film tightly to prevent the material from deforming it, while simultaneously performing longitudinal back heat sealing on the film bag. Before performing transverse heat sealing, the wound film needs to be placed between the two second heat-sealing blocks 421. Then, the fifth driving component 422 drives one of the second heat-sealing blocks 421 to slide closer to the other second heat-sealing block 421. The two second heat-sealing blocks 421 heat seal the lower transverse opening of the film bag. After heat sealing, a certain amount of material is first put into the film bag. Then, the fifth driving component 422 drives one of the second heat-sealing blocks 421 to slide away from the other second heat-sealing block 421. When the upper opening of the film bag moves down to between the two second heat-sealing blocks 421, the fifth driving component 422 drives one of the second heat-sealing blocks 421 to slide closer to the other second heat-sealing block 421 to perform transverse heat sealing on the upper opening of the film bag. This process is repeated to form an independent plastic film bag.

[0051] The cutting mechanism 5 includes a cutting blade 51 and a sixth driving member 52. The cutting blade 51 is installed in the middle of one of the second heat-sealing blocks 421. The sixth driving member 52 is connected to the cutting blade 51 and can drive the cutting blade 51 to slide closer to or away from the other second heat-sealing block 421. A slot is opened in the middle of the other second heat-sealing block 421. When the cutting blade 51 slides, it can enter and exit the slot. After the transverse heat-sealing assembly 42 heat-seals the opening of the film bag, the cutting blade 51 cuts off the heat-sealed opening of the film bag to complete the individual packaging.

[0052] The frame 1 is provided with a material drop platform 30 below the transverse heat sealing assembly 42. The rear side of the material drop platform 30 is provided with a pusher 301 and a seventh drive 302 that drives the pusher to slide laterally. The packaged material falls onto the material drop platform 30 and is pushed out by the pusher 301 to complete the finished product unloading.

[0053] The film feeding mechanism 3 includes a feeding frame 31, which is located above the bag forming machine. A drive roller 32, a driven roller 33, a tension roller, and a transmission roller 35 are rotatably mounted on the feeding frame 31. A passageway for film conveying is provided between the drive roller 32 and the driven roller 33. The tension roller is located below the drive roller 32 and can move towards or away from the drive roller 32. A motor 36 is mounted on the feeding frame 31 to drive the drive roller 32. The film passes through the passageway between the drive roller 32 and the driven roller 33, wraps around the tension roller, and then wraps around the transmission roller 35 to be conveyed to the bag forming machine. The motor 36 drives the film to rotate. The active roller 32 rotates to drive the film transport, and the tension roller ensures that the film transport is always in a tensioned state. The loading rack 31 includes a pair of support arms I and a pair of support arms II. The rear ends of the two support arms are mounted on the frame 1 through support rods. The active roller 32 and the driven roller 33 are arranged laterally at the front ends of the two support arms I. The front ends of the two support arms II are provided with roller mounting openings. The support arm I is located above the support arm II. The roller end with the film roll is located inside the roller mounting opening, which reduces the installation height of the film roll, making it easier to install manually. It also lowers the center of the loading rack 31, making the structure of the loading rack 31 more stable and less prone to shaking.

[0054] The frame 1 is also equipped with a pressure roller mechanism for driving film conveying. The pressure roller mechanism includes a first pressure roller group 40 located between the longitudinal heat sealing assembly 41 and the transverse heat sealing assembly 42. The first pressure roller group 40 includes a first driving pressure roller 401 and a first driven pressure roller 402 arranged opposite to each other. The first driving pressure roller 401 and the first driven pressure roller 402 are rotatably mounted on the frame 1 via a first rotating shaft A403 and a second rotating shaft B604, respectively. The frame 1 is equipped with an eighth driving member 50 that drives the first rotating shaft A403 to rotate. The eighth driving member 50 is equipped with a motor 36. The first pressure rollers rotate under the action of the eighth driving member 50, driving the film located between the two first pressure rollers downward to perform vertical heat sealing and transverse heat sealing. The pressure roller mechanism also includes a second pressure roller group 60 located at the inlet of the longitudinal heat sealing assembly 41. The second pressure roller group 60 includes a first driving pressure roller 401 and a first driven pressure roller 402 arranged opposite to each other. The second active pressure roller 601 and the second driven pressure roller 602 are rotatably mounted on the frame 1 via the second rotating shaft A603 and the second rotating shaft B604. The second rotating shaft A603 and the first rotating shaft A403 rotate synchronously via the transmission mechanism 70. The addition of the second pressure roller group allows the film to be clamped on the upper and lower sides of the longitudinal heat-sealing component, thereby effectively preventing the soft film bag from being stretched and deformed downwards due to the material it contains. The two sets of pressure roller groups also improve the film conveying effect. When the first pressure roller group is working, it drives the second pressure roller group to work through the transmission mechanism. The specific structure and working principle of the feeding rack and the pressure roller mechanism have been clearly described in the Chinese Utility Model Patent with authorization announcement number CN216233153U, so they will not be described in detail in this application.
