Description

A fully automatic packaging line using double-loop container bags

Technical Field

The invention relates to the field of packaging equipment, in particular to a full-automatic packaging line using double-loop container bags.

Background Art

Many fields require the use of bulk bags to package product materials, and in order to improve production efficiency, many manufacturers have adopted fully automatic packaging systems for material packaging operations. However, the fully automatic packaging systems in the existing technology generally have problems such as complex structural processes, high manufacturing costs, and large footprint.

For example, the patent with the authorization announcement number CN116424652B discloses a fully automatic packaging machine for solid fluids and an automatic bagging and packaging method. The device includes a packaging machine main unit, a ton bag loading device, a vacuum packaging chamber and other parts. In the process of loading ton bags, after the device transfers the ton bag to the upper platform of the bag opening frame, a pair of bag-holding mechanical arms on the bag-holding and bag-covering mechanism move synchronously so that a pair of bag-holding mechanical palms on the bag-holding mechanical arms extend into the opened bag mouth of the ton bag, and then the pair of bag-holding mechanical palms move synchronously. The bag opening of the ton bag is tightened by moving in the reverse direction, and then the bag-holding and bag-covering mobile frame moves toward the main machine of the packaging machine. At the same time, the bag-holding mechanical arm swings upward at a certain angle through the swing mechanism, so that the bag opening of the ton bag is covered with the lifting filling barrel of the main machine of the packaging machine. After the bagging is completed, the bag opening fixing cylinder needs to be started to drive the top pressure head to hold the bag opening to fix it. After the material filling is completed, the bag-holding mechanical arm needs to swing and retreat to separate from the ton bag, and then the ton bag needs to be tied and weighed. The entire structure and action process control of the device are relatively complicated, the manufacturing cost is high, and the floor space is relatively large.

Another example is a patent with authorization announcement number CN115384866B that discloses a fully automatic rice packaging device and packaging method, which includes a packaging bag feeding device, a packaging bag moving device, a material dropping device, a bag clamping device, a conveying device, etc. When the packaging bag feeding device is working, the upper suction component descends to lift the uppermost packaging bag in the storage component and then flips it over, the bag guiding component clamps the lifted packaging bag and pulls it to the side to put it into the driving component, and then the driving component drives the packaging bag to move and feed, and the packaging bag moving device connects the packaging bag The feeding device and the blanking device, and when the bag transfer device is working, the opening cylinder is extended to make the opening frame extend into the bag mouth, and then the clamping cylinder clamps the two sides of the bag, and then the driving motor drives the rotating shaft to rotate, and the bag is turned over and inserted into the lower end discharge port of the conveying device. Then when the blanking device is working, the bag is put on the blanking control component, the clamping plate clamps the bag on the control board, and then the bag clamping component clamps the bag from both sides to fix it, and then the blanking bagging operation is carried out. After the bagging is completed, the bag needs to be clamped by the bag clamping device and then transferred. This device also has the problems of relatively cumbersome structure and action process control and high manufacturing cost.

The advantages and positive effects of the present invention are:

1. The present invention utilizes a bag loading device to realize the automatic bag loading and opening functions of a container bag, and directly utilizes the swing of a bag loading swing arm to connect the bag opening of the container bag with the feeding opening at the lower end of the feeding device. Its various actions are not only simple and convenient to control, but also save the time of conveying the container bag to the loading station, improve production efficiency, and also reduce the floor space occupied by the bag loading device.

2. The vibrating weighing device of the present invention integrates the functions of vibration, weighing and conveying, and the vibrating weighing device uses the grid bars on the upper side of the lifting frame to pass through the gap between two adjacent conveyor belt rollers and lift the upper layer of the weighing conveyor belt, thereby lifting the container bag. In this way, when the vibrators on the lower sides of both ends of the lifting frame apply vibration to the container bag, the vibration is mainly absorbed by the lifting frame, and the weighing sensor on the lower side of the conveying seat will not be affected by the vibration, so it will not affect the subsequent weighing accuracy. In addition, the overall footprint of the vibrating weighing device is only slightly larger than that of the weighing and conveying device, but compared with the method in which each device is independently arranged in the prior art, the footprint of the vibrating weighing device is greatly reduced. At the same time, the vibrating weighing device also further saves the conveying time of the container bag and improves production efficiency.

3. The bag opening heat sealing device of the present invention utilizes the bag opening input plug plate at the lower end of the bag opening input swing arm to automatically fold the bag opening of the container bag into the gap between the hot pressing riveting block and the lower supporting seat to form a bag opening folded edge, and then utilizes the hot pressing steel nails on the lower side of the hot pressing riveting block to insert into the bag opening folded edge to complete the heat sealing operation. The entire sealing process is completed automatically, and the hot pressing steel nails can pass through the multi-layer materials forming the bag opening, so that it is not affected by the thickness of the bag opening. At the same time, the present invention forms a columnar sealing point with sufficient density on the bag opening folded edge by each hot pressing steel nail to ensure that the bag opening heat sealing is firm and reliable.

4. The lifting and shaping device of the present invention hooks and gathers the lifting rings of the container bag on both sides of the upper end of the container bag through relative movement of the hooks on both sides, and then lifts the container bag as a whole to achieve natural hanging shaping. The operation is simple and convenient, and the shaping efficiency of the container bag is improved. After the hooks on both sides of the lifting and shaping device move inwardly into place, the hook connecting sections of the two hooks form an acute-angle groove for accommodating the lifting rings of the container bag on both sides to ensure that the two lifting rings of the container bag are gathered to the middle position of the upper side of the container bag to form an isosceles triangle shape, thereby ensuring that the shape of the container bag naturally stacked on the conveyor belt device after being released can have sufficient consistency to facilitate subsequent process operations, that is, to ensure the shaping quality of the container bag.

5. The overall layout of the present invention is compact, and the structure of each device is simple and easy to control. The floor space of the bag loading device is reduced, and the feeding device and the vibrating weighing device are respectively arranged at the upper and lower ends of the loading frame, and their floor space is the floor space of the loading frame. At the same time, the conveyor belt device passes through the lower end of the bag mouth heat sealing device and the lower end of the lifting and shaping device to realize the transfer and transportation of the container bag. Therefore, compared with the prior art, the overall floor space of the present invention is greatly reduced.

The present invention can also adopt other suitable structures, such as the mechanism in patent CN219750938U that uses an electric push rod to drive two sets of push plates to move relative to each other to achieve the correction and adjustment of the position of the container bag.

The feeding device 3 is a well-known technology in the art, for example, the feeding device in the patent CN204415754U can be used. The conveyor belt device 7 is a commercially available product.

The working principle of the present invention is:

As shown in FIG. 16 , the present invention adopts a double-ring bulk bag to package materials, wherein the upper end of the bulk bag 9 is provided with a cylindrical bag opening 901 with a reduced diameter, and lifting rings 902 are provided on both sides of the bag opening 901. The bag opening 901, the lifting rings 902 and the main body of the bulk bag 9 are all integrally arranged. In addition, as shown in FIG. 3 , the bulk bags 9 are stacked layer by layer on the bag storage rack 102 of the bag loading device 1.

When the present invention is working, as shown in Figures 2 to 6, the bag loading device 1 first picks up the container bag 9, opens it, and then puts it on the feeding port 301 on the lower side of the feeding device 3. Specifically, the bag transfer suction cup 1033 on the bag transfer mechanism 103 is actuated to absorb and transfer the uppermost container bag 9 inside the bag storage rack 102 to the top of the bag opening station 1011, and then the lower bag opening suction cup 1041 in the bag opening mechanism 104 absorbs and fixes the lower side of the bag opening 901 of the container bag 9, and the upper bag opening suction cup 403 sucks the upper side of the bag opening 901 and rises to a set height to open the bag opening 901 of the container bag 9, and then the upper bag swing arm in the bag loading mechanism 105 is 1055 is driven to fall by the bag upper swing arm cylinder 1054, and the bag clamping element 1058 at the front end of the bag upper swing arm 1055 clamps and fixes the upper and lower sides of the bag opening 901 of the container bag 9 respectively, and then the bag upper swing arm 1055 is driven by the bag upper swing arm cylinder 1054 to swing upward to fit the bag opening 901 of the container bag 9 on the feeding port 301, and as shown in Figure 1, the container bag 9 is also transferred to the loading rack 2 at the same time, which not only makes the bag loading operation simple and convenient, but also saves the bag loading and transportation time of the container bag, improves production efficiency, and reduces the overall footprint of the production line. In addition, the upper bag translation frame 1053 in the upper bag mechanism 105 can also cooperate with the action to realize the transfer of the container bag 9. For example, the upper bag swing arm 1055 is first driven to fall and maintain a vertical state by the upper bag swing arm cylinder 1054, and then the upper bag translation frame 1053 retreats to the set position, so that the upper and lower sides of the bag mouth of the container bag 9 enter the corresponding bag clamping elements 1058 respectively, and then the bag clamping elements 1058 start clamping, and then the upper bag translation frame 1053 moves forward to the set position, and finally the upper bag swing arm 1055 swings upward to buckle the bag mouth 901 of the container bag 9 on the feeding port 301.

After the bag mouth 901 of the container bag 9 is buckled on the feeding port 301, the feeding device 3 starts feeding the container bag 9, and after the container bag 9 is opened, its lower end falls on the vibrating weighing device 4 at the lower end of the loading frame 2. As shown in Figures 7 to 9, when the lifting frame 402 in the vibrating weighing device 4 is raised, the grid bars 4021 on the upper side of the lifting frame 402 pass through the gap between two adjacent conveyor belt rollers 4012 and lift the upper layer of the weighing conveyor belt 4013. At this time, the container bag 9 is also lifted up, and the vibrator 404 on the lifting frame 402 applies vibration to the container bag 9 to make the material inside the container bag 9 fully fall and compact. At the same time, the vibration is mainly caused by the lifting frame 402. The vibration-damping lifting device 405 on the lower side absorbs (through a gas spring or a vibration-damping block) and will not affect the weighing sensor 403. When the bulk bag 9 is loaded, the lifting frame 402 descends and drives the bulk bag 9 back to the weighing conveying device 401. At this time, the lifting frame 402 is separated from the upper layer of the weighing conveyor belt 4013, and the bulk bag 9 is only supported by the conveying seat 4014. At this time, the weighing sensor 403 on the lower side of the conveying seat 4014 can complete the weighing operation of the bulk bag 9. If the weight of the bulk bag 9 is qualified, the weighing conveyor belt 4013 will transport the bulk bag 9 to the conveyor belt device 7, and then transport it to the bag mouth heat sealing device 5 through the conveyor belt device 7. In addition, one end of the conveying seat 4014 is provided with a driven belt roller 4016 with an adjustable position. The present invention adjusts the tension of the weighing conveyor belt 4013 by adjusting the position of the driven belt roller 4016. This can ensure that the upper layer of the weighing conveyor belt 4013 can be lifted to a suitable height by the lifting frame 402 and that the upper layer of the weighing conveyor belt 4013 has a suitable degree of slack, thereby minimizing the impact of vibration on the weighing sensor 403 on the lower side of the conveying seat 4014. On the other hand, when the lifting frame 402 falls back, the weighing conveyor belt 4013 can drive the container bag 9 to move and smoothly transport it to the next process.

After the container bag 9 is conveyed to the conveyor belt device 7, the container bag 9 is first conveyed into the bag mouth heat sealing device 5 through the conveyor belt device 7 to complete the bag mouth 9 sealing operation, wherein the hot pressure riveting block 504 in the bag mouth heat sealing device 5 is first raised to a set height to ensure that there is enough space between it and the lower support seat 505 for the bag mouth folding edge to be inserted, and at the same time, the bag mouth input swing arm 501 is in a raised state. When the container bag 9 is transferred to the set position in the heat sealing frame 506 through the conveyor belt device 7, the swing arm driving device 5021 in the swing arm driving assembly 502 is started, and the bag mouth input swing arm 501 is driven to fall through the driving arm 5022 and the driving shaft 5026. At this time, the bag mouth input plug plate 5011 at the lower end of the bag mouth input swing arm 501 will drive the container bag 9 The bag opening 901 is folded into the gap between the hot pressure riveting block 504 and the lower supporting seat 505 to form a bag opening folded edge, and then the hot pressure riveting block 504 is driven down by the hot pressure lifting device 503 and cooperates with the lower supporting seat 505 to clamp the bag opening folded edge to complete the heat sealing operation, wherein the hot pressure steel nails 5041 on the lower side of the hot pressure riveting block 504 can pass through the multi-layer material forming the bag opening, so that it is not affected by the thickness of the bag opening, and the heat generated by the hot pressure riveting block 504 when it is powered on will also be conducted to each hot pressure steel nail 5041, and the position where the hot pressure steel nail 5041 passes through the bag opening will be melted to form a columnar seal, so that the present invention can ensure that the bag opening is firmly and reliably heat-sealed through the columnar seal with sufficient density formed on the bag opening folded edge by each hot pressure steel nail 5041.

After the container bag 9 is sealed, it continues to be transported by the conveyor belt device 7 to the lifting and shaping device 6 for shaping, wherein the lifting bracket 602 in the lifting and shaping device 6 first descends to a set height to ensure that the hook 605 can hook the lifting ring 902 on the container bag 9. At this time, the set height of the lifting bracket 602 can be adjusted according to the height of the lifting ring 902 on the container bag 9. In addition, at this time, the two hooks 605 are in an open state to ensure that the container bag 9 can enter the shaping station. After the sealed container bag 9 is transported by the conveyor belt device 7 into the shaping station in the shaping frame 601, the two hooks 605 are driven inward by the hook retracting device 604 on the corresponding side to move inward so that the lifting rings 902 on both sides are retracted in the container bag 9. The lifting bracket 602 is moved to the middle position on the upper side, and then the lifting bracket 602 rises and pulls up the container bag 9 through the hook 605. At this time, the container bag 9 is naturally hung and shaped by gravity. After the container bag 9 is hung for a set time, the hook 605 and the lifting ring 902 remain in a retracted state and the container bag 9 is placed back on the conveyor belt device 7 on the lower side through the descending action of the lifting bracket 602. In this way, the appearance of the container bag 9 after lifting and shaping tends to be consistent, and the two lifting rings 902 are gathered to the middle position on the upper side of the container bag 9 to form an isosceles triangle shape, which can maximize the guarantee that the shape of the container bag 9 naturally stacked on the conveyor belt device 7 after being released has sufficient consistency, and the shaped container bag 9 is sent to the next process through the conveyor belt device 7.
