Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to packaging equipment and a packaging method. Background Art

[0002] The bag-feeding automatic packaging machine replaces the traditional manual packaging and realizes packaging automation for large and small enterprises. The operator only needs to load a stack of finished packaging bags into the feeding structure of the equipment, and the equipment can automatically take bags, open bags, pack bags, seal and output them, such as the "automatic packaging equipment with transfer mechanism" disclosed in the Chinese utility model patent with application number CN202022419947.X. The bag-feeding automatic packaging machine has a very wide range of applications. It only needs to match different metering devices according to different materials to realize the full-automatic packaging of products such as granules, powders, blocks, liquids, soft cans, toys, hardware, etc.

[0003] The accordion bag is a common packaging bag on the market, and has side accors folded into the bag body on the left and right sides. Figure 2 As shown in the figure, the bag body can form a sealed cavity structure by simply sealing the upper and lower sides of the accordion bag. However, the existing packaging machines have the following problems: First, because the accordion bag contains materials, the bag mouth is often not flat. Therefore, after the accordion bag is sealed, the bag mouth is prone to wrinkles or misalignment, affecting the packaging quality and visual effect of the product, and even affecting the firmness of the packaging, affecting the transportation and use of the packaged product; Second, the production links of some packaging machines are not designed reasonably, and the time loss of the accordion bag, materials, and finished products in the transfer process of each process increases, affecting production efficiency.

When the piston rod of the fifth cylinder 870 is extended, the deoxidizer can be stuck in the dividing trough 830. When the piston rod of the fifth cylinder 870 is retracted, the deoxidizer can enter the guide trough 860 under the action of gravity, thereby controlling the timing of the deoxidizer falling, so that when the bagging machine 500 pushes the material B into the accordion bag A, the divided deoxidizer falls on the material B and is loaded into the accordion bag A together, thereby improving the effectiveness of deoxidizer bagging. The design of the dividing block 840, multiple dividing troughs 830, the fifth cylinder 870, etc. can meet the multi-station packaging requirements of the packaging equipment, avoiding the setting of too many deoxidizer automatic unloading machines 810, which increases the cost.

[0057] Combination Fig. 9The bag unpacking machine 600 of this embodiment includes an air jet pipe 610, an air flow generating device 620 and a moving device 630. At least one air jet pipe 610 is provided outside the side accordion A1 on both sides of the accordion bag A. The air jet of the air jet pipe 610 faces the bag opening A4 of the accordion bag A and is located in the same plane as the middle fold line A5 of the accordion bag A. The air flow generating device 620 is connected to the air jet pipe 610 to supply high-pressure air flow to the air jet pipe 610. The moving device 630 adopts a linear lifting module 230, which includes a support frame 631, a shaft sleeve 632 and a sixth cylinder 633 fixed on the support frame 631, an optical axis 634 inserted in the shaft sleeve 632, and a moving part 635 fixed to one end of the optical axis 634 and the piston rod of the sixth cylinder 633. The jet pipe 610 is fixed on the moving part 635 of the moving device 630, and the moving part 635 is driven up and down by the cylinder 633 to move the jet pipe 610 to both sides of the accordion bag A. Of course, the moving device 630 can also adopt a horizontal moving module 220 or a rotating device. After the material B is bagged, the jet pipe 610 sprays air to the middle fold line A5 of the side accordion A1 of the accordion bag A to blow the side accordion A1 of the accordion bag A back into the bag body, and at the same time, the first cylinder 331 and the second cylinder 333 drive the first group of vacuum suction cups 310 and the second group of vacuum suction cups 320 to move toward each other to close the bag opening A4, and the first driving device 130 drives the first belt pressing conveyor device 110 and the second belt pressing conveyor device 120 to move toward each other to clamp the bag opening A4 of the accordion bag A that has been smoothed, and then the bag opener 300 and the bag sorter 600 are reset, and the bag clamping conveyor 100 conveys the accordion bag A to the sealing machine 700 for sealing. like Fig.10 As shown, the angle between the jet pipe 610 and the accordion bag A in this embodiment is α, 15°≤α≤50°, and by making the jet pipe 610 and the accordion bag A form a certain angle, the angle between the airflow ejected from the jet pipe 610 and the accordion bag A is also α. Fig.11 , the small dots in the figure are airflow paths. During the whole process of the bag opener 300 and the bag clamping conveyor 100 closing the bag opening A4 of the accordion bag A, the bag unscrambler 600 can continuously arrange the bag opening A4 of the accordion bag A by spraying airflow. After the airflow is sprayed to the side accordion A1 of the accordion bag A, it can flow along the middle fold line A5 of the side accordion A1 toward the bag opening A4. As the bag opening A4 of the accordion bag A gradually closes, negative air pressure gradually occurs between the side accordion A1 above the middle fold line A5 and the side accordion A1 below the middle fold line A5, which can gradually adsorb the two together, thereby making the bag opening A4 of the accordion bag A neatly closed. In addition, since the bag unscrambler 600 of this embodiment uses airflow as the bag unscrambling medium, it can adapt to materials of different shapes, has a wide range of applications, and has a certain degree of universality.

[0058] Combination Fig.12 and Fig.13The sealing machine 700 of this embodiment includes a sealing machine body 710, a conveying platform 720 and a transition mechanism 730. The transition mechanism 730 is composed of an upper guide plate 731, a lower guide plate 732, an upper guide wheel 733 and a lower guide wheel 734. The sealing machine body 710 and the conveying platform 720 can be purchased directly from the market. The sealing machine body 710 is arranged at one end of the first belt pressing conveyor device 110 and the second belt pressing conveyor device 120. An upper guide plate 731 is arranged between the sealing machine body 710 and the first belt pressing conveyor device 110, and the upper guide plate 731 is located on one side of the first belt pressing conveyor device 110. A lower guide plate 732 is arranged between the sealing machine body 710 and the second belt pressing conveyor device 120, and the lower guide plate 732 is located on the first belt pressing conveyor device 110. On one side of the second belt-pressing conveyor 120, an upper guide wheel 733 is provided at one end of the upper guide plate 731 close to the first belt-pressing conveyor 110, and a lower guide wheel 734 is provided at one end of the lower guide plate 732 close to the second belt-pressing conveyor 120. The upper guide wheel 733 and the lower guide wheel 734 are mutually staggered along the conveying direction of the accordion bag A, and the lower end line of the upper guide wheel 733 and the upper end line of the lower guide wheel 734 are located in the same plane, so that when the accordion bag A passes between the upper guide plate 731 and the lower guide plate 732, the upper guide wheel 733 and the lower guide wheel 734 assist in pressing the bag opening A4 of the accordion bag A to ensure the flatness of the bag opening A4. The conveying platform 720 is provided at one end of the supporting conveyor 140, and is used to support and convey the accordion bag A containing the material B. The sealing machine 700 of this embodiment cooperates closely with the bag clamping conveyor 100. After the bag sorting process is completed, the bag clamping conveyor 100 conveys the accordion bag A containing material B to the sealing machine 700 for sealing. The sealing machine 700 ensures the flatness of the bag opening A4 of the accordion bag A during the process of the bag clamping conveyor 100 transitioning the accordion bag A to the sealing machine 700 through the transition mechanism 730, thereby ensuring the flatness of the sealing of the sealing machine body 710.

[0059] The packaging method of the above packaging equipment includes the following processes:

[0060] S10: The bag feeding machine 200 conveys the accordion bag A to the bag clamping conveyor 100;

[0061] S20: the feeder 400 delivers material B to the bagging machine 500;

[0062] S30: The bag clamping conveyor 100 conveys the accordion bag A to the bag opening machine 300:

[0063] S40: The bag opening machine 300 cooperates with the bag clamping conveyor 100. When the bag opening machine 300 opens the accordion bag A, the bag clamping conveyor 100 releases the accordion bag A.

[0064] S50: the bagging machine 500 puts the material B conveyed by the feeder 400 into the accordion bag A;

[0065] S60: the bag unscrambler 600 sprays airflow toward the middle fold line A5 of the side accordion A1 of the accordion bag A to fold the side accordion A1 into the bag. At the same time, the bag opener 300 closes the bag opening A4, and the bag clamping conveyor 100 clamps the bag opening A4. Then, the bag opener 300 and the bag unscrambler 600 are reset.

[0066] S70: The bag-clamping conveyor 100 clamps and conveys the accordion bag A containing the material B to the sealing machine 700 for sealing.

[0067] In the above process, process S10 can be executed synchronously with S30 and S50. When the bag clamping conveyor 100 conveys the accordion bag A to the bag opening machine 300, the bag feeding machine 200 simultaneously extracts the accordion bag A and conveys the accordion bag A to the bag clamping conveyor 100. When the bag clamping conveyor 100 releases the accordion bag A (the bag clamping conveyor 100 is in the open state), the bag feeding machine 200 just places the accordion bag A between the first belt pressing conveyor device 110 and the second belt pressing conveyor device 120 of the bag clamping conveyor 100. Process S10 can also be executed synchronously with process S40, or synchronously with process S50. In processes S40 and S50, the bag clamping conveyor 100 is in an open state. If the speed at which the bag feeding machine 200 conveys the accordion bag A to the bag clamping conveyor 100 is fast enough, the accordion bag A can be placed between the first belt pressing conveyor device 110 and the second belt pressing conveyor device 120 of the bag clamping conveyor 100 before the bag clamping conveyor 100 is closed. Of course, process S10 can also be executed synchronously with processes S40 and S50. Process S20 can be executed synchronously with process S30, or synchronously with process S40, or all three can be executed synchronously. Material B needs to be delivered to the place before the bagging machine 500 loads material B into the accordion bag A to ensure the effectiveness of bagging. Process S30 and process S70 are executed synchronously. This embodiment connects the entire production line by conveying the accordion bag A through the bag clamping conveyor 100. The design is reasonable, and each link is closely coordinated and synchronized, which saves the time of handing over the accordion bag A, material B, etc. between each process, and is conducive to improving the production efficiency of the packaging equipment. The timing of the coordination between the various parts of the packaging equipment can be directly controlled by pre-programming in the PLC, or by setting corresponding sensors for induction control.
