Description

Technical Field

[0001] This application relates to the technical field of food industrial processing and intelligent manufacturing equipment, and in particular to a fully automatic food packaging bag and box packing device. Background Technology

[0002] In the food production industry, the production scale of packaged foods such as pre-made soups is constantly expanding, and the requirements for production efficiency and quality are also increasing. With the growth in market demand, companies have an increasingly urgent need for automation and reliability in the packaging and boxing processes for packaged foods. Efficient packaging and boxing processes can not only improve a company's production capacity but also reduce production costs and enhance the competitiveness of its products in the market.

[0003] In traditional bagged food packaging, manual operation is typically used. Workers need to sort the packaged bags one by one and arrange them into boxes according to a specific pattern. This method relies heavily on manpower, requiring workers to perform repetitive sorting, arranging, and packing actions for extended periods, resulting in high labor intensity and low efficiency. Meanwhile, automated packaging lines operate at much faster speeds, while manual sorting has limited speed, easily becoming a bottleneck in the production line, leading to situations where front-end packaging machines are waiting for materials or back-end packing is delayed. Furthermore, there is a risk of secondary contamination. Workers touching the surface of the packaging bags, especially during soup packaging where condensation may occur, can easily breed bacteria or introduce contaminants, thus affecting food hygiene and safety. This problem urgently needs to be addressed. Summary of the Invention

[0004] In order to improve the efficiency of packing bags and reduce the risk of secondary contamination, thereby ensuring food hygiene and safety, this application provides a fully automatic food packaging bag packing device.

[0005] This application provides a fully automatic food packaging bag and box packing device, which adopts the following technical solution: A fully automatic food packaging bag and box packing device, comprising: The feeding mechanism receives the finished food packaging bags at its first end and performs the feeding operation. A variable speed conveying mechanism is disposed at the end of the feeding mechanism. The variable speed conveying mechanism includes a reversing conveying component, a first conveying component, and a second conveying component. The first end of the reversing conveying component is located directly below the end of the feeding mechanism, and the conveying direction of the reversing conveying component is perpendicular to the conveying direction of the feeding mechanism. The first end of the first conveying component is located directly below the end of the reversing conveying component, and the conveying direction of the first conveying component is perpendicular to the conveying direction of the reversing conveying component. The second conveying component is located behind the first conveying component and is connected to the first conveying component. The conveying speed of the second conveying component is greater than the conveying speed of the first conveying component. A correction mechanism, located behind the variable speed conveying mechanism, is used to automatically correct the packaging bags during conveying to a synchronized front and back state. A packing mechanism, located behind the straightening mechanism, is used to automatically pack the straightened packaging bags into a packaging box; The control system is electrically connected to the feeding mechanism, the variable speed conveying mechanism, the straightening mechanism, and the packing mechanism.

[0006] By adopting the above technical solution, during the packing process of the packaging bags, the first end of the feeding mechanism receives the finished food packaging bags and performs the packing operation. The variable speed conveying mechanism is set at the end of the feeding mechanism to receive the packaging bags and separate them to prevent stacking. Specifically, the reversing conveying component receives the loaded packaging bags and reverses their direction to transfer them to the first conveying component. The second conveying component is located behind the first conveying component and is connected to it. The conveying speed of the second conveying component is greater than that of the first conveying component, so that the packaging bags are transferred from the feeding mechanism to the first conveying component and from the first conveying component. During the process of conveying to the second conveying component, the spacing between the packaging bags is increased, thereby achieving separation between the packaging bags. Then, the straightening mechanism straightens the packaging bags in the conveying process to a synchronous state with the front and back sides in order to improve the packing quality. Finally, the packing mechanism automatically packs the straightened packaging bags into the packaging box. The feeding mechanism, variable speed conveying mechanism, straightening mechanism, and packing mechanism are all controlled by the control system. The entire packing process has a high degree of automation, which is conducive to improving the packing efficiency of packaging bags and reducing the risk of secondary contamination, thereby helping to ensure food hygiene and safety. It is worth mentioning that the variable speed conveying mechanism solves the problem of material stacking caused by automated conveying.

[0007] Preferably, the correction mechanism includes a vertical adjustment component and an air blowing component. The vertical adjustment component is located behind the second conveying component to receive the flat-ly conveyed packaging bag and adjust the packaging bag to be conveyed in a vertical state. The air blowing component is located at the end of the vertical adjustment component to sense the front and back positions of the packaging bag and blow the vertically positioned packaging bag down to a synchronous front and back state.

[0008] The packaging bags containing pre-made soup are conveyed flat, and the packaging bags have a front and a back. The vertical adjustment component receives the packaging bags conveyed flat and adjusts the packaging bags to a vertical position for conveying. During the vertical conveying process, the air blowing component can sense the front and back positions of the packaging bags and blow the vertical packaging bags down to a synchronous front and back position, which helps to improve the consistency of packaging bag packing, thereby improving the packing quality.

[0009] Preferably, the vertical adjustment component includes a bottom support, a flipping conveyor, and a side support. The bottom support and the flipping conveyor are arranged side by side behind the second conveying component. The front end of the flipping conveyor and the bottom support work together to receive and convey the packaging bag. The rear end of the flipping conveyor flips the packaging bag to an upright position. The rear end of the flipping conveyor, the bottom support, and the side support form a channel for conveying the packaging bag in an upright position.

[0010] By adopting the above technical solution, the front end and bottom support of the flipping conveyor jointly receive and transport the packaging bag. As the transport proceeds, the rear end of the flipping conveyor flips the packaging bag to an upright position. At this time, the bottom support is located at the bottom of the upright packaging bag to provide bottom support, and the rear end and side support of the flipping conveyor are respectively located on opposite sides of the upright packaging bag to provide side support. This allows the rear end, bottom support, and side support of the flipping conveyor to form a channel for transporting the packaging bag in an upright position. The flipping action and the transport action do not interfere with each other, making it convenient and fast.

[0011] Preferably, the bottom support includes a horizontally driven support conveyor belt, the flipping conveyor includes a flipping conveyor belt with a horizontal front end and a vertical rear end, the side support includes a vertically driven side conveyor belt, and the side conveyor belt is located directly above the support conveyor belt. The flipping conveyor belt flips upwards towards the side conveyor belt from the side away from the support conveyor belt. The rear ends of the support conveyor belt, the flipping conveyor belt, and the side conveyor belt form a channel for vertically conveying the packaging bag.

[0012] By adopting the above technical solution, the support conveyor belt, the flip conveyor belt, and the side conveyor belt simultaneously transport the packaging bag. As the flip conveyor belt flips, the packaging bag changes from a horizontal transport state to a vertical transport state. The vertical transport state of the packaging bag is supported and limited by the support conveyor belt, the side conveyor belt, and the flip conveyor belt after flipping, thereby realizing the transformation of the packaging bag from horizontal transport to vertical transport. This facilitates the subsequent air blowing component to sense the front and back of the packaging bag and blow it down to a synchronous front and back state.

[0013] Preferably, the air blowing assembly includes a QR code sensor, an upper limiting part, and a lower air blowing part. The QR code sensor is disposed at the end of the vertical adjustment assembly for sensing the QR code on the packaging bag. The upper limiting part is disposed at the end of the vertical adjustment assembly for keeping the packaging bag in an upright state for conveying. The lower air blowing part is located on both sides below the upper limiting part and blows air towards the packaging bag that is limited by the upper limiting part. The QR code sensor and the lower air blowing part are both electrically connected to the control system. When the QR code sensor senses the QR code on the packaging bag, the lower air blowing part blows air towards the lower side of the packaging bag that is limited by the upper limiting part. When the QR code sensor does not sense the QR code on the packaging bag, the lower air blowing part blows air towards the other side of the lower side of the packaging bag that is limited by the upper limiting part.

[0014] By adopting the above technical solution, the upper limiting part maintains the vertical state of the packaging bag. During this process, the QR code sensor senses the QR code on the packaging bag. When the QR code sensor senses the QR code on the packaging bag, the lower blowing part blows air onto the lower side of the packaging bag that is limited by the upper limiting part, so that the packaging bag returns to the horizontal conveying state. When the QR code sensor does not sense the QR code on the packaging bag, the lower blowing part blows air onto the other side of the lower end of the packaging bag that is limited by the upper limiting part, so that the packaging bag returns to the horizontal conveying state, thereby realizing the correction of the packaging bag after blowing to the front and back synchronous state.

[0015] Preferably, the upper limiting part includes two sets of support frames and limiting rods arranged symmetrically. The two sets of limiting rods are arranged in parallel and form a channel for the packaging bag to pass through in an upright state. The two sets of limiting rods are located on both sides of the upper half of the packaging bag, and the ends of the two sets of limiting rods facing the upright adjustment component are flared.

[0016] By adopting the above technical solution, the support frame supports the limiting rod and makes the limiting rod only limit the upper end of the packaging bag in the vertical state. The two sets of limiting rods are flared at the end facing the vertical adjustment component, so that the packaging bag can enter the channel formed by the two sets of limiting rods in the vertical state.

[0017] Preferably, the lower air blowing part includes a first hair dryer and a second hair dryer. The first hair dryer and the second hair dryer are located directly below the upper limiting part and are respectively disposed on both sides of the upright packaging bag. The first hair dryer and the second hair dryer are both electrically connected to the QR code sensor. When the QR code sensor senses the QR code on the packaging bag, the QR code sensor sends an electrical signal to the first hair dryer. When the QR code sensor does not sense the QR code on the packaging bag, the QR code sensor sends an electrical signal to the second hair dryer.

[0018] By adopting the above technical solution, the first and second blowers work independently. When the QR code sensor detects the QR code on the packaging bag, the QR code sensor sends an electrical signal to the first blower, and the first blower blows air towards the bottom of the packaging bag. Since there is no limit at the bottom of the packaging bag, the packaging bag tilts during the conveying process. When the QR code sensor does not detect the QR code on the packaging bag, the QR code sensor sends an electrical signal to the second blower, and the second blower blows air towards the bottom of the packaging bag. Both tilting actions cause the packaging bag to tilt with its front facing up.

[0019] Preferably, the packing mechanism includes a stepping conveyor assembly, a packaging box conveyor assembly, and a transfer assembly. The stepping conveyor assembly is provided with partition plates evenly spaced along its conveying direction, and two adjacent partition plates form a space for accommodating a packaging bag. The stepping conveying distance of the stepping conveyor assembly is set to the width of a packaging bag. The packaging box conveyor assembly is located on one side of the stepping conveyor assembly. Both the packaging box conveyor assembly and the stepping conveyor assembly pass through the transfer assembly. The transfer assembly is used to transfer the packaging bag conveyed in the stepping conveyor assembly to the packaging box in the packaging box conveyor assembly for packing operation.

[0020] By adopting the above technical solution, as the stepping conveyor component conveys intermittently, each space formed by two adjacent partition plates can accommodate a packaging bag. Both the packaging box conveying component and the stepping conveyor component pass through the transfer component, so that the transfer component can transfer the packaging bag conveyed in the stepping conveyor component to the packaging box in the packaging box conveying component for packing operation.

[0021] Preferably, the transfer assembly includes a frame, a transfer drive, and a plurality of suction cups. The frame is disposed on the conveying path of the stepping conveyor assembly and the packaging box conveyor assembly. The transfer drive is disposed within the frame to drive the suction cups to reciprocate between the stepping conveyor assembly and the packaging box conveyor assembly. The suction cups are connected to a vacuum system.

[0022] By adopting the above technical solution, the frame supports the transfer drive and several suction cups. The suction cups perform adsorption operations on the packaging bags. The transfer drive drives the suction cups to move back and forth between the non-conveying component and the packaging box conveying component, thereby realizing the transfer of the packaging bags in the stepping conveying component to the packaging box for packing operations.

[0023] Preferably, the transfer assembly further includes a mounting base and a retracting cylinder. A plurality of suction cups are evenly spaced on the mounting base, and the retracting cylinder is mounted on the mounting base to drive two adjacent suction cups to reciprocate in a direction that moves closer to or further away from each other.

[0024] By adopting the above technical solution, the mounting base supports the gathering cylinder and suction cups. Since the distance between two adjacent partition plates in the stepping conveyor assembly is the width of a packaging bag, the gathering cylinder drives two adjacent suction cups to move away from each other in order to pick up multiple packaging bags. During the packing process, the gathering cylinder drives two adjacent suction cups to move closer to each other so that the picked-up packaging bags are packed more compactly into the packaging box, thereby improving packing efficiency and packing compactness.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a feeding mechanism, a variable speed conveying mechanism, a straightening mechanism, a boxing mechanism, and a control system, during the boxing process of packaging bags, the first end of the feeding mechanism receives the finished food packaging bags and performs the feeding operation for boxing. The variable speed conveying mechanism is set at the end of the feeding mechanism to receive the packaging bags and separate them to prevent stacking. The variable speed conveying mechanism includes a reversing conveying component, a first conveying component, and a second conveying component. The reversing conveying component receives the fed packaging bags and reverses their direction to transfer them to the first conveying component. The second conveying component is located behind and connected to the first conveying component. The conveying speed of the second conveying component is greater than that of the first conveying component, so that the packaging bags... During the transfer of bags from the feeding mechanism to the first conveying component and from the first conveying component to the second conveying component, the spacing between the bags increases, thereby achieving separation between the bags. Then, the straightening mechanism straightens the bags in the conveying process to a synchronized front and back state to improve the packing quality. Finally, the packing mechanism automatically packs the straightened bags into the packaging box. The feeding mechanism, variable speed conveying mechanism, straightening mechanism, and packing mechanism are all controlled by the control system. The entire packing process is highly automated, which helps to improve the packing efficiency of the bags and reduces the risk of secondary contamination, thus helping to ensure food hygiene and safety. It is worth mentioning that the variable speed conveying mechanism solves the problem of material stacking caused by automated conveying.

[0026] 2. By setting up a vertical adjustment component and an air blowing component, the packaging bags containing pre-made soup are conveyed horizontally. The packaging bags have a front and a back. The vertical adjustment component receives the horizontally conveyed packaging bags and adjusts them to an upright position for conveying. During the vertical conveying process, the air blowing component can sense the front and back positions of the packaging bags and blow the upright packaging bags down to a synchronized front and back position, which helps to improve the consistency of packaging bag packing and thus improves packing quality.

[0027] 3. By setting up a bottom support, a flipping conveyor, and side supports, the front end of the flipping conveyor and the bottom support work together to receive and transport the packaging bag. As the transport proceeds, the rear end of the flipping conveyor flips the packaging bag to an upright position. At this time, the bottom support is located at the bottom of the upright packaging bag to provide bottom support, and the rear end of the flipping conveyor and the side supports are located on opposite sides of the upright packaging bag to provide side support. This allows the rear end of the flipping conveyor, the bottom support, and the side supports to form a channel for transporting the packaging bag in an upright position. The flipping action and the transport action do not interfere with each other, making it convenient and fast. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses a fully automatic food packaging bag and box packing device, referring to... Figure 1 The system includes a feeding mechanism 1, a variable speed conveying mechanism 2, a straightening mechanism 3, a boxing mechanism 4, and a control system. The feeding mechanism 1 receives the finished food packaging bags at its first end and performs the feeding operation. The variable speed conveying mechanism 2 is located at the end of the feeding mechanism 1 to receive the packaged bags after feeding and to separate the packaged bags from each other to prevent stacking. The straightening mechanism 3 is located behind the variable speed conveying mechanism 2 and is used to automatically straighten the packaged bags during conveying to a synchronized front and back state. The boxing mechanism 4 is located behind the straightening mechanism 3 and is used to automatically pack the straightened packaged bags into packaging boxes. The control system is electrically connected to the feeding mechanism 1, variable speed conveying mechanism 2, straightening mechanism 3, and boxing mechanism 4, so that the feeding mechanism 1, variable speed conveying mechanism 2, straightening mechanism 3, and boxing mechanism 4 are all controlled by the control system. The entire boxing process has a high degree of automation, which is conducive to improving the boxing efficiency of the packaging bags and reducing the risk of secondary contamination, thereby helping to ensure food hygiene and safety. It is worth mentioning that the variable speed conveying mechanism 2 solves the problem of stacking caused by automated conveying.

[0039] Reference Figure 1 and Figure 2 The feeding mechanism 1 uses an inclined conveyor belt to feed and transport materials from bottom to top. The bottom end of the inclined conveyor belt receives the finished packaging bags. It should be noted that baffles 6 are evenly spaced along the conveying direction of the inclined conveyor belt. The baffles 6 support the packaging bags during the inclined feeding process to prevent the packaging bags from sliding down the slope.

[0040] Reference Figure 1 and Figure 2 When the packaging bags are conveyed uphill to the top of the feeding mechanism 1, they fall one by one into the variable speed conveying mechanism 2. Specifically, the variable speed conveying mechanism 2 includes a reversing conveying component 21, a first conveying component 22, and a second conveying component 23. The first end of the reversing conveying component 21 is located directly below the end of the feeding mechanism 1, so that the packaging bags at the end of the feeding mechanism 1 fall naturally into the reversing conveying component 21. It should be noted that the reversing conveying component 21, the first conveying component 22, and the second conveying component 23 are all horizontally conveyed. The conveying direction of the reversing conveying component 21 is perpendicular to the conveying direction of the feeding mechanism 1. The first end of the first conveying component 22 is located directly below the end of the reversing conveying component 21, so that the packaging bags conveyed to the end of the reversing conveying component 21 fall into the first conveying component 22. The conveying direction of the first conveying component 22 is perpendicular to the conveying direction of the reversing conveying component 21. The second conveying component 23 is located behind the first conveying component 22 and is connected to the first conveying component 22. The conveying speed of the second conveying component 23 is greater than the conveying speed of the first conveying component 22. Through two descent processes and the difference in conveying speed between the first conveying component 22 and the second conveying component 23, the spacing between the packaging bags is increased, thereby achieving separation between the packaging bags and preventing them from piling up and affecting subsequent packing operations. In this embodiment, the reversing conveying component 21, the first conveying component 22, and the second conveying component 23 are all conveyed by a motor driving a conveyor belt through conveyor rollers; the only difference is in their orientation and conveying direction, which will not be elaborated here. It is worth mentioning that the reversing conveying component 21, the first conveying component 22, and the second conveying component 23 are all electrically connected to the control system, which is controlled by a PLC to adjust the individual conveying speeds of the reversing conveying component 21, the first conveying component 22, and the second conveying component 23.

[0041] Reference Figure 2 and Figure 3 In order to detect whether the packaging bags are completely separated in the variable speed conveying mechanism 2, the fully automatic food packaging bag packing device is also equipped with a vision inspection mechanism 7 and a return mechanism 8. The vision inspection mechanism 7 is located at the rear end of the second conveying component 23 to perform photo detection. Both the vision inspection mechanism 7 and the return mechanism 8 are electrically connected to the control system. When the vision inspection mechanism 7 detects that there is an overlap of packaging bags, the vision inspection mechanism 7 sends an electrical signal to the control system. The control system then controls the return mechanism 8 to return the overlapping packaging bags to the feeding mechanism 1. In this embodiment, the vision inspection mechanism 7 is selected as a CCD photo detection system, which will not be described in detail here.

[0042] Reference Figure 2 and Figure 3The return mechanism 8 includes a pusher cylinder 81, a pusher plate 82, and a return conveyor line 83. The pusher cylinder 81 is horizontally fixed on one side of the end of the second conveying component 23. The pusher plate 82 is fixedly connected to the piston rod of the pusher cylinder 81. The return conveyor line 83 is located on one side of the second conveying component 23 and the feeding mechanism 1, and the conveying direction of the return conveyor line 83 is opposite to the conveying direction of the second conveying component 23. The first end of the return conveyor line 83 is aligned with the pusher plate 82, and the end of the return conveyor line 83 leads to the bottom end of the feeding mechanism 1. When the vision inspection mechanism 7 detects that the packaging bags are stacked and overlapping, the vision inspection mechanism 7 sends an electrical signal to the control system. The control system controls the piston rod of the pusher cylinder 81 to stretch so as to drive the pusher plate 82 to push the stacked packaging bags into the return conveyor line 83. The return conveyor line 83 returns the packaging bags to the feeding mechanism 1 for re-feeding. In this embodiment, the return conveyor line 83 also uses a motor to drive the conveyor belt through the conveyor rollers for conveying, which will not be described in detail here.

[0043] Reference Figure 4 and Figure 5 The packaging bags containing pre-made soup are conveyed flat, and the packaging bags have a front and a back. In order to maintain the consistency of the packaging bags in the box, the straightening mechanism 3 straightens the packaging bags to a synchronous front and back state. Specifically, the straightening mechanism 3 includes a vertical adjustment component 31 and an air blowing component 32. The vertical adjustment component 31 is set behind the second conveying component 23 to receive the packaging bags conveyed flat and adjust the packaging bags to a vertical state for conveying. The air blowing component 32 is set at the end of the vertical adjustment component 31 to sense the front and back positions of the packaging bags and blow the vertical packaging bags down to a synchronous front and back state.

[0044] Reference Figure 4 and Figure 5The vertical adjustment component 31 includes a bottom support 311, a flipping conveyor 312, and a side support 313. The bottom support 311 and the flipping conveyor 312 are arranged side by side behind the second conveying component 23. The front end of the flipping conveyor 312 and the bottom support 311 together receive and convey the packaging bag. The rear end of the flipping conveyor 312 flips the packaging bag to an upright position. The rear end of the flipping conveyor 312, the bottom support 311, and the side support 313 form a channel for conveying the packaging bag in an upright position. Specifically, the bottom support 311 includes a horizontally driven support conveyor belt, the flipping conveyor 312 includes a flipping conveyor belt with a horizontal front end and a vertical rear end, and the side support 313 includes a vertically driven side conveyor belt, with the side conveyor belt located directly above the support conveyor belt. The flipping conveyor belt moves away from the support conveyor belt and flips upwards towards the side conveyor belt as it is conveyed, so that the packaging bag flips from a horizontal conveying state to a vertical conveying state as it is conveyed by the support conveyor belt, the flipping conveyor belt, and the side support belt. The rear ends of the support conveyor belt and the flipping conveyor belt, together with the side conveyor belt, form a channel for the packaging bag to be conveyed in a vertical state.

[0045] Reference Figure 4 and Figure 5 When the packaging bag is conveyed in an upright position, the air blowing assembly 32 blows the packaging bag down to a synchronized front and back position. Specifically, the air blowing assembly 32 includes a QR code sensor 321, an upper limiting part 322, and a lower air blowing part 323. The QR code sensor 321 is fixedly installed on one side of the end of the upright adjustment assembly 31 to sense the QR code on the packaging bag. The upper limiting part 322 is fixedly installed at the end of the upright adjustment assembly 31 to keep the packaging bag in an upright position for conveying. The lower air blowing part 323 is located on both sides below the upper limiting part 322 and blows air towards the packaging bag that is limited by the upper limiting part 322. It should be noted that the upper limiting part 322 limits the upper end of the packaging bag to be upright, and the lower air blowing part 323 blows air towards the lower end of the packaging bag, so that the blowing operation can tilt the packaging bag. The QR code sensor 321 and the lower air blowing part 323 are both electrically connected to the control system. When the QR code sensor 321 senses the QR code on the packaging bag, the lower air blowing part 323 blows air to one side of the lower end of the packaging bag that is limited by the upper limit part 322, so that the packaging bag tilts and returns to the horizontal conveying state. When the QR code sensor 321 does not sense the QR code on the packaging bag, the lower air blowing part 323 blows air to the other side of the lower end of the packaging bag that is limited by the upper limit part 322, so that the packaging bag tilts and returns to the horizontal conveying state. The packaging bag is corrected to a synchronous state of front and back after the two tilting actions.

[0046] Reference Figure 5 and Figure 6The upper limiting part 322 includes two sets of support frames 3221 and limiting rods 3222 arranged symmetrically on the left and right. The two sets of support frames 3221 support the two sets of limiting rods 3222 respectively. The two sets of limiting rods 3222 are arranged in parallel and form a channel for the packaging bag to pass through in an upright state. It should be noted that the two sets of limiting rods 3222 are located on both sides of the upper half of the packaging bag, and the end of the two sets of limiting rods 3222 facing the upright adjustment component 31 is flared to facilitate the packaging bag to enter the channel formed by the two sets of limiting rods 3222 in an upright state.

[0047] according to Figure 5 and Figure 6 The lower air blowing section 323 includes a first air blower 3231 and a second air blower 3232. The first air blower 3231 and the second air blower 3232 are located directly below the upper limiting section 322 and are respectively disposed on both sides of the vertically positioned packaging bag. Both the first air blower 3231 and the second air blower 3232 are electrically connected to the QR code sensor 321. When the QR code sensor 321 senses the QR code on the packaging bag, the QR code sensor 321 sends an electrical signal to the first air blower 3231, and the first air blower 3231 blows air to one side of the lower end of the packaging bag. Since the lower end of the packaging bag is not limited, the packaging bag tilts during the conveying process and returns to a horizontal conveying state. When the QR code sensor 321 does not sense the QR code on the packaging bag, the QR code sensor 321 sends an electrical signal to the second air blower 3232, and the second air blower 3232 blows air to the other side of the lower end of the packaging bag. The packaging bag tilts during the conveying process and returns to a horizontal conveying state. Both tilting actions make the packaging bag tilt synchronously in both the front and back sides.

[0048] Reference Figure 7 After the front and back of the packaging bag is corrected during the conveying process, the packing mechanism 4 automatically packs the packaging bag into the packaging box. Specifically, the packing mechanism 4 includes a stepping conveyor assembly 41, a packaging box conveyor assembly 42, and a transfer assembly 43. The stepping conveyor assembly 41 uses a stepper motor to drive the conveyor belt through the conveyor rollers for conveying. It should be noted that the conveying direction of the stepping conveyor assembly 41 is perpendicular to the conveying direction of the second conveyor assembly 23, and the stepping conveyor assembly 41 is evenly spaced with partition plates 5 along its conveying direction. A space for accommodating one packaging bag is formed between two adjacent partition plates 5, and the stepping conveying distance of the stepping conveyor assembly 41 is set to the width of one packaging bag. The corrected packaging bag enters the space through the side of the stepping conveyor assembly 41. The packaging box conveying assembly 42 is located on one side of the stepping conveying assembly 41 for conveying packaging boxes. Both the packaging box conveying assembly 42 and the stepping conveying assembly 41 pass through the transfer assembly 43, and the conveying stops after the packaging box is conveyed into the transfer assembly 43, so that the transfer assembly 43 can transfer the packaging bag conveyed to the side of the packaging box in the stepping conveying assembly 41 into the packaging box for packing operation.

[0049] Reference Figure 7 and Figure 8 The transfer assembly 43 includes a frame 431, a transfer drive 432, and several suction cups 433. The frame 431 covers the conveying path of the stepping conveyor assembly 41 and the packaging box conveyor assembly 42. The transfer drive 432 is disposed within the frame 431 and is used to drive the suction cups 433 to reciprocate between the stepping conveyor assembly 41 and the packaging box conveyor assembly 42. In this embodiment, the transfer drive 432 is driven in the form of a spider robot, which has the advantages of balanced force, fast action, and high precision. The suction cups 433 are connected to a vacuum system. When both the packaging bags and the packaging boxes are conveyed into the transfer assembly 43, the spider robot drives the suction cups 433 to pick up multiple packaging bags from the stepping conveyor assembly 41. Then, the spider robot puts the picked-up packaging bags into the packaging box, thereby realizing automatic boxing operation.

[0050] In addition, the transfer assembly 43 also includes a mounting base 434 and a retracting cylinder 435. Several suction cups 433 are evenly spaced on the mounting base 434. The retracting cylinder 435 is mounted on the mounting base 434 and is used to drive adjacent suction cups 433 to reciprocate in a direction that moves closer to or further away from each other. In this embodiment, there are three sets of suction cups 433. The three sets of suction cups 433 simultaneously pick up three packaging bags for boxing operations. The suction cup 433 located in the middle position is fixedly mounted on the bottom of the mounting base 434. The suction cups 433 located on both sides reciprocate in a direction that moves closer to or further away from the suction cup 433 located in the middle position through the retracting cylinder 435. The retracting cylinder 435 is a bidirectional cylinder. The suction cups 433 located on both sides are respectively fixedly connected to two piston rods in opposite directions of the bidirectional cylinder. When suction cup 433 picks up the packaging bag in the stepping conveyor assembly 41, the piston rod of the retracting cylinder 435 stretches to widen the distance between the three sets of suction cups 433. When suction cup 433 puts the packaging bag into the packaging box, the piston rod of the retracting cylinder 435 retracts to shorten the distance between the three sets of suction cups 433, so that the three picked-up packaging bags are gathered together, making the packaging bags more compactly placed into the packaging box, thereby improving the packing efficiency and packing compactness.

[0051] The implementation principle of the fully automatic food packaging bag packing device in this application embodiment is as follows: the packaging bags are fed from bottom to top via an inclined conveyor belt. Baffle 6 prevents the packaging bags from sliding downhill during the incline. After being conveyed uphill to the top of the feeding mechanism 1, the packaging bags fall into the reversing conveyor assembly 21. After being conveyed to the end of the reversing conveyor assembly 21, the packaging bags fall into the first conveyor assembly 22, and then into the second conveyor assembly 23. The conveying speed of the second conveyor assembly 23 is greater than that of the first conveyor assembly 22. Through two falling processes and the interaction between the first and second conveyor assemblies, the packaging bags are successfully packed. The difference in conveying speed of the conveying component 23 increases the spacing between the packaging bags, thereby achieving separation between the packaging bags to avoid them piling up and affecting subsequent packing operations. The vision inspection mechanism 7 detects whether the packaging bags are completely separated after the variable speed conveying. When the vision inspection mechanism 7 detects that there is a phenomenon of overlapping packaging bags, it sends an electrical signal to the control system. The control system controls the piston rod of the pusher cylinder 81 to stretch, thereby driving the pusher plate 82 to push the overlapping packaging bags into the return conveyor line 83. The return conveyor line 83 returns the packaging bags to the feeding mechanism 1 for re-feeding. Subsequently, the support conveyor belt, the tilting conveyor belt, and the side conveyor belt work together to transport the packaging bag. As the tilting conveyor belt tilts, the packaging bag changes from a horizontal transport state to a vertical transport state. Then, the QR code sensor 321 senses the QR code on the packaging bag. When the QR code sensor 321 senses the QR code on the packaging bag, it sends an electrical signal to the first blower 3231. The first blower 3231 blows air towards the lower side of the packaging bag. Since there is no limit at the lower end of the packaging bag, the packaging bag tilts during transport and returns to a horizontal transport state. When the QR code sensor 321 does not sense the QR code on the packaging bag, it sends an electrical signal to the second blower 3232. The second blower 3232 blows air towards the other side of the lower end of the packaging bag. During the conveying process, the packaging bags tilt and return to a horizontal conveying state, and both tilting actions cause the packaging bags to tilt synchronously in a forward and reverse state. After the forward and reverse sides of the packaging bags are corrected, the packaging bags enter the space formed by the two partition plates 5 through the side of the stepping conveyor component 41 and continue to be conveyed in the stepping conveyor component 41 to the position of the transfer component 43. At the same time, the packaging boxes are conveyed in the packaging box conveyor component 42 to the position of the transfer component 43. The spider robot arm drives the suction cup 433 to pick up multiple packaging bags from the stepping conveyor component 41. Then the spider robot arm puts the picked-up multiple packaging bags into the packaging box, thereby realizing the automatic boxing operation. The entire boxing process has a high degree of automation, which is conducive to improving the boxing efficiency of packaging bags and reducing the risk of secondary contamination, thus helping to ensure food hygiene and safety.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
