Description

Technical Field

[0001] The present application relates to the field of food automation technology, and in particular to a vertical filling and packing machine and a food automated boxing and packaging production line. Background Art

[0002] In the food industry, in order to improve production efficiency, automated production equipment is needed. The food packaging production line is the core of fully automated food packaging. Take the packaging process as an example. Figure 1-2 As shown, the package is a rectangular plastic bag, which needs to be packaged in a carton. The package can be packed in three layers in the carton, with 12 bags in each layer of 3*4. In the traditional packaging method, the package bag has its edges facing up, and the carton is a preformed box. The package is easily overturned in the forward direction when it is pushed horizontally in the carton. That is, the horizontal push method will be unstable when stacking multiple layers, and the aspect ratio is not good. The material can only be grabbed vertically and put into the carton. However, due to the large grabbing distance of the traditional vertical grabbing method, long-distance grabbing is prone to shaking, resulting in the loss of packages. In addition, due to the particularity of the package, there will be problems such as large leakage and failure to form a vacuum, which will eventually lead to the loss of packages when grabbing and putting them into the box.

[0100] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0101] The present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0102] The embodiment of the present application provides an automated food packaging and packing production line, which is a production line for automatically packing packages, and includes a front-end packaging conveying device and a carton conveying device, a carton pushing device, a carton opening device, an opening and closing platform, a packaging pushing device, a negative pressure generating device, a lowering device, a carton sealing device, etc. These devices can realize the processes of conveying, folding, bottom sealing, and lid sealing of cartons, and can also realize the processes of assembling, packing, and conveying packages. Finally, the packages can be arranged into three layers in a 3*4 manner with the air outlet facing upward and placed in a carton. For details, see Figure 1-2 As shown, this production line can greatly improve the efficiency of packaging production and has a very high degree of automation.

[0103] The detailed structure and working process of the production line are described below in conjunction with the accompanying drawings:

[0104] like Figure 3 The structure diagram of the carton conveying device 1 is shown. The carton conveying device 1 is one of the devices for realizing the conveying of the carton, which includes a frame, the upper part of the frame has an inclined table, the two ends of the inclined table are horizontal tables, and the inclined and horizontal tables are provided with parallel rollers at intervals. The rollers are driven by a motor or a synchronous belt mechanism to roll in one direction by themselves, so that the carton can move from a high place to a low place. The table is supported by a bracket below, and the bracket has six legs. The legs are provided with a high adjustment structure, such as a thread adjustment structure, and the bracket is also provided with an electric control box. The two horizontal tables at the two ends are respectively provided with a photoelectric switch 14 for detecting when the carton enters the horizontal table at the high place and a photoelectric switch 11 for detecting when the carton enters the horizontal table at the low place, respectively determining the carton entry and carton push station arrival signals. The position where the high horizontal table contacts the inclined table is also provided with a baffle 13 that moves up and down in the vertical direction. The lower part of the baffle 13 is driven by a cylinder 12, and the surface of the baffle 13 is parallel to the axis of the roller 15.

[0105] refer to Figure 1 , Fig.11 and Fig.12 When in use, the carton enters from the high horizontal surface (photoelectric switch 14), and the drum keeps running. At this time, the output shaft of the cylinder 12 is in an extended state, so that the baffle is in an upward extended state. The baffle can position the carton to prevent the carton from deflecting. When the photoelectric switch 14 detects the carton, the output shaft of the cylinder 12 is retracted, driving the baffle to fall, making way for the carton to pass through. The carton moves from right to left to the low horizontal surface. At this time, the photoelectric switch 11 detects whether there is a carton. If there is a carton, a signal is given to prompt the carton pushing device 2 to push.

[0106] like Figure 4 The structure diagram of the carton pushing device 2 is shown. The carton pushing device 2 is an important device for realizing stable clamping and feeding of carton to the carton support device. It is necessary to ensure that the carton is stable and non-deflected during the conveying process. It includes an upper synchronous belt mechanism 21, which includes a synchronous belt, a driving pulley, a driven pulley and a servo motor, etc., two L-shaped vertical rods driven by the synchronous belt mechanism to move horizontally, and the lower end of the vertical rod is connected to a frame. A cylinder 22 is vertically installed on the frame. The output shaft axis of the cylinder 22 extends along the length direction of the synchronous belt mechanism 21. Two cylinders 22 are symmetrically arranged, and each cylinder 22 is connected to a clamp rod 23. The clamp rod 23 is hinged on the frame through a vertical axis. The clamp rod 23 can rotate along a horizontal plane. A pull rod is hinged on the clamp rod 23. The cylinder 22 drives the pull rod to telescopically move to drive the clamp rod 23 to swing horizontally. When the clamp rods 23 on both sides swing to be perpendicular to the frame or the two clamp rods 23 continue to rotate in a direction close to each other, the carton can be clamped.

[0107] like Figure 4 and Fig.11 As shown, when in use, after the photoelectric switch 11 on the carton conveying device 1 detects that the carton is in place, the cylinder 22 drives the clamping rod 23 to rotate the clamping rod 23 90° from the current state and clamp the carton, so as to keep the carton stable when pushing the carton. After clamping the carton, the synchronous belt mechanism drives the clamping rod and the cylinder to push the carton into the carton support device of the next station, and returns to the starting point after the pushing is completed and waits for the next action.

[0108] like Figure 5 The structure diagram of the carton opening device 3 is shown. The carton opening device 3 is a device for realizing carton opening and carton conveying, which includes a platform, a side clamping synchronous belt 32, a width adjustment hand wheel 31 for adjusting the distance between the clamping synchronous belts 32 on both sides, a box cover long side guide plate 33, a box cover short side cylinder 34, a guide rod 36, etc. Among them, the width adjustment hand wheel 31 is used to adjust the distance between the clamping synchronous belts 32 on both sides to adapt to cartons of different widths, the box cover long side guide plate 33 is used to guide the long side of the carton cover and to open the long side of the carton cover, the box cover short side cylinder 34 is used to open the short side of the carton cover, and the guide rod 36 is used to adjust the height of the bracket installed by the box cover long side guide plate 33 and the box cover short side cylinder 35 to adapt to cartons of different heights. The long side guide plate 33 of the box cover includes a main support portion with an L-shaped cross-section and a guide plate 331 connected to the front end of the main support portion. The guide plate 331 is an upwardly raised structure, including two plates at an obtuse angle, which can guide the long side of the box cover to the main support portion of the long side guide plate of the box cover.

[0109] like Figure 5 and Fig.11 As shown, when in use, the carton pushing device 2 pushes the carton into the side clamp synchronous belt 32, and the carton is driven by the side clamp synchronous belt 32 to continue to move, and the long side of the box cover automatically enters the long side guide plate 33 of the box cover through the guide plate 331, so that the long side of the box cover is bent to both sides. When it moves to the set position, the side clamp synchronous belt 32 stops together with the carton, and the short side cylinders 34 and 35 of the box cover extend to both sides respectively, so that the short side of the box cover is bent to both sides, and then wait for the packaged objects to enter the carton. The long side guide plate 33 of the box cover can be adjusted up and down by the guide rod 36 to adapt to different carton heights, and the carton stops at this time. Figure 6 Directly below the opening and closing support plate 43.

[0110] like Figure 6The structure diagram of the opening and closing platform 4 is shown. The opening and closing platform 4 is one of the more important devices of the device. It can realize the guiding and positioning of the packaged objects and prevent the packaged objects from moving over a long distance during packing and causing the package to be dropped. It includes a bracket and a platform. A fixed support plate 45 is arranged on the platform. Two sets of anti-overturning rods 41 are arranged above the fixed support plate 45. A rectangular opening is arranged adjacent to the fixed support plate 45. Two opening and closing cylinders 44 are symmetrically installed on the front and rear sides of the rectangular opening. The two opening and closing cylinders 44 are respectively connected to the opening and closing support plates 43. The horizontal movement of the opening and closing support plates 43 can be realized by the action of the opening and closing cylinders 44. The horizontal movement of the opening and closing support plates 43 can open or open the rectangular opening. The carton to be opened is placed directly below the rectangular opening. Two tightening cylinders 42 are symmetrically arranged on the left and right sides of the rectangular opening. A tightening plate is respectively connected to the output shafts of the two tightening cylinders 42. The tightening action of the packaged objects is realized by the action of the two tightening cylinders 42. The anti-overturning rod 41 includes a horizontal section 411 and a tilting section 412. The tilting section 412 guides the incoming packages so that the packages can smoothly enter the horizontal section 411. The horizontal section 411 presses on the packages to prevent the packages from overturning. The opening and closing support plate 43 plays a supporting role when the packages just enter. When the suction device sucks the packages and the tightening cylinder clamps the packages, the opening and closing support plate 43 needs to be opened to expose the rectangular opening, so as to facilitate the smooth downward movement of the packages and place them in the carton.

[0111] Figure 7 is a schematic diagram of the structure of the package pushing device 5, the function of which is to push the package to Figure 6 The opening and closing platform 4 includes a crossbeam arranged along the moving direction of the packaged object, a servo-driven synchronous belt 55 is arranged on the crossbeam, a guide rail extending along the length direction thereof is also arranged on the crossbeam, a crossbar is slidably mounted on the guide rail, the crossbar is fixed relative to the servo-driven synchronous belt 55 and moves along the guide rail as the servo-driven synchronous belt 55 moves, a vertical rod is connected to the end of the crossbar, and a vertically arranged push plate 57 is connected to the vertical rod for pushing the packaged object.

[0112] like Figure 6 , Figure 7 and Fig.11 As shown, when in use, the opening and closing platform and the package pushing device are used in combination. When the assembled 3*4 arranged packages are ready to be pushed in, the package pushing device 5 pushes the packages onto the opening and closing platform 4, the lifting cylinder 56 drives the push plate 57 to fall, and the servo drives the synchronous belt to move to push the packages along the Figure 6 The package moves in the direction of the arrow, and the anti-overturning rod 41 presses on the package to prevent the package from overturning forward and backward during movement. Figure 6 When the opening and closing support plate 43 is on, the photoelectric switch on the opening and closing support plate 43 gives a signal, and the double-sided tightening cylinder 42 clamps the package. At this time, the push plate 57 remains in the falling state, waiting for Figure 8 The medium negative pressure generating device 6 sucks the whole layer of packaging material. After the sucking time is reached, Figure 7 The middle lifting cylinder 56 drives the push plate 57 to rise. Figure 6 The middle opening and closing cylinder 44 drives the opening and closing support plate 43 to open in the opposite direction, and the packaged goods are waiting to enter the carton vertically downward. There is another group of opening and closing cylinders 44 below the fixed support plate, and the two opening and closing support plates 43 are opened to both sides from the middle through two opening and closing cylinders 44 in opposite directions.

[0113] like Figure 8 The negative pressure generating device 6 is a schematic diagram of the structure. The negative pressure generating device 6 is used to absorb the packaging. It uses a large flow suction method to absorb a layer of packaging above the carton, and is used to send a layer of packaging into the carton through the lower feeding device 7 after the opening and closing support plate 43 is opened, thereby avoiding the problem of packaging falling off and package switching caused by long-distance movement. It includes a fan 61 that can generate a large flow of wind, a pipeline connected to the air inlet of the fan, a reversing valve 62 and a conversion cavity 63 arranged on the pipeline, and a suction pipe 64 connected to the conversion cavity 63, etc. There are four suction pipes 64.

[0114] Fig. 9 It is a structural diagram of the downward delivery device 7, which is used to deliver the packages sucked by the negative pressure generating device 6 into the carton. It includes a gantry bracket, two guide columns 78 are respectively provided on both sides of the gantry bracket, and sliders are slidably mounted on the guide columns 78. A horizontally arranged connecting plate 77 is arranged between the guide columns 78 on both sides, and the two ends of the connecting plate 77 are respectively connected to the two sliders on both sides, and the connecting plate 77 slides up and down stably along the four guide columns 78 through four sliders. Servo-driven synchronous belts 75 are also symmetrically arranged on both sides of the gantry bracket, and the two ends of the connecting plate 77 are respectively fixedly connected to the synchronous belts, and the connecting plate 77 can be driven to move up and down when the synchronous belt moves. A vertical beam is fixed below the connecting plate 77, and a suction cavity 76 is provided at the lower end of the vertical beam. Among them, Figure 8 The conversion cavity in the air suction chamber is mounted on the connecting plate 77, and the air suction pipe 64 is connected to the air suction cavity 76. The negative pressure generating device 6 is integrally mounted on the bracket of the lower delivery device 7.

[0115] like Figure 8 , Fig. 9 and Fig.11 As shown, the negative pressure generating device 6 and the downward delivery device 7 are used in combination. After the package is ready, the servo-driven synchronous belt 75 drives the suction cavity 76 to press on the package. At this time, the reversing valve 62 is actuated, and the suction cavity 76 starts to suck air. After a delay period of time, all the air inside the cavity is sucked away, and the inside of the cavity becomes negative pressure to suck the package. Figure 6The middle opening and closing support plate 43 opens, and the servo-driven synchronous belt 75 continues to drive the suction chamber 76 to move vertically downward until the group of materials is placed in the carton. At this time, the reversing valve 62 reverses to allow ventilation in the suction chamber 76 to prevent the negative pressure from continuing to absorb the packaged material and causing the two to become inseparable. The carton needs to be filled with three layers, and this action needs to be repeated three times to complete the filling of a box. The downward distance of the downward delivery device can be the same each time, and the packaged material can be delivered to the top layer of the carton. At this time, although the packaged material has not reached the bottom, due to the action of gravity and the guiding effect of the side wall of the carton, the packaged material that has left the suction chamber can smoothly descend and automatically reach its position.

[0116] like Fig.10 The structure diagram of the box sealing device 8 is shown, and the box sealing device 8 is used to fold up the box cover of the carton filled with packaging and seal it with tape. It mainly includes a bracket, a conveying roller shaft, a side clamping belt 81, an upper and lower adjustment device 83, a long side guide rod 84 of the box cover, a short side cylinder 85 of the box cover, an upper sealing tape device 82, etc. Among them, the conveying roller shaft is a plurality of roller shafts arranged in parallel along the moving direction of the carton. The side clamping belt is used to clamp and drive the carton to be conveyed backward, and can move smoothly under the action of the roller shaft. The distance of the side clamping belt can be adjusted by adjusting the hand wheel to adapt to different carton widths. The upper and lower adjustment device is used to support and adjust the height of the long side guide rod of the box cover, the short side cylinder of the box cover and other structures to adapt to cartons of different heights. The long side guide rod of the box cover is used to guide the long side of the box cover. When the carton moves, the inclined guide rod is used to make the long side of the box cover of the carton bend by itself. The cylinder for the short side of the box cover is used to fold the short side of the rear side of the moving carton inward, and to maintain the short side of the box cover in the folded position by relying on the lower surface of the device until the opening is sealed by the upper sealing tape device.

[0117] A specific embodiment of a vertical filling and packing machine: The vertical filling and packing machine comprises an opening and closing platform, including a bracket and a platform, a fixed pallet is arranged on the platform, two sets of anti-tipping rods are symmetrically arranged above the fixed pallet and extend in the moving direction of the packaged object, a material channel for the packaged object to pass through is formed between the anti-tipping rods and the fixed pallet, a rectangular opening is arranged on the platform at the rear side of the fixed pallet, opening and closing cylinders are symmetrically arranged on the front and rear sides of the rectangular opening, the output shafts of the opening and closing cylinders are respectively connected to the opening and closing pallets, the opening and closing pallets move horizontally to open or close the rectangular opening, and the rectangular opening is opened or closed by the opening and closing cylinders. A carton placing station for placing cartons is provided below the rectangular opening; a carton opening support device is provided below the opening and closing pallet for positioning the carton and supporting the long and short sides of the carton cover; a package pushing device is provided on one side of the opening and closing platform for pushing the arranged packages onto the opening and closing pallet through the anti-tipping rod; and a lowering device and a negative pressure generating device are located above the opening and closing pallet, the negative pressure generating device is used to absorb the packages, and the lowering device is used to send the absorbed packages through the rectangular opening into the carton below. By setting up the opening and closing platform, the packages do not need to move a long distance after being sucked, but only need to move downward a certain distance to directly enter the carton. There is no need to carry the packages up or move horizontally, so the possibility of package substitution is reduced. In order to prevent the packages from tipping over when being pushed over, an anti-tip rod with a simple structure but good anti-tip effect is specially designed. The anti-tip rod presses the packages from the top of the packages, and the packages can move stably between the fixed pallet and the anti-tip rod when pushed by the package pushing device.

[0118] Preferably, tightening cylinders are symmetrically arranged on the left and right sides of the rectangular opening, and tightening plates are connected to the output shafts of the tightening cylinders for clamping the packages. This makes it difficult for the packages to spread out after the opening and closing pallet is opened to both sides. The anti-overturning rod includes a horizontal section and an upwardly tilted section, and the tilted section is arranged on the side away from the closing pallet to guide the packages that are about to enter the material channel. The horizontal section is the main anti-overturning section, and the tilted section plays a guiding role, so that the packages can easily enter the horizontal section when pushed, and there will be no jamming. Guide plates are symmetrically arranged on the left and right sides of the fixed pallet for guiding the packages. This ensures that the packages will not spread out or deflect to the left and right sides when they are pushed and moved. The negative pressure generating device includes a fan whose suction force is much greater than the weight of the packages, a reversing valve for switching the wind direction, and a plurality of suction pipes arranged in parallel for sucking the packages, and each suction pipe is connected to the main pipe of the negative pressure generating device through a conversion cavity. Compared with the conventional adsorption method, it uses a large-flow suction method to ensure that the package is not easily dropped when the material is sucked and moved. The carton opening device includes a side clamp synchronous belt to drive the carton to move, and also includes a long side guide plate of the box cover and a short side cylinder of the box cover to respectively open the long side and short side of the box cover. The purpose of this is to ensure that when filling the carton with packaging, the box cover will not be driven to fold inward, resulting in the packaging being unable to enter the box.

[0119] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
