Description

Technical Field

[0001] This invention relates to the technical field of fragile goods packaging, specifically to an integrated air column bag inflation and tearing mechanism. Background Technology

[0002] Fragile items, especially glass bottles, need to be packaged in an outer sleeve, such as... Figure 1 The air column bag shown includes an outer ring air column body, a central inner cavity 94, and an upper air column cover 96. A guide roll 91 is located at the top of the upper air column cover 96. An inflation port is located within the guide cavity 91. Gas is injected through the inflation port, directly into the upper air column cover 96 and the outer ring air column body to complete inflation. The outer ring air column body is formed by assembling an inner air column body 92 and an outer air column body 93. A simple one-way valve 95 is provided at the position of each independent inflation port on the guide roll 91. The simple one-way valve 95 ensures that the inflation port can only be used for inflation and will not leak. In actual use, especially in the medical packaging industry, the safety protection of glass bottles is particularly important. The packaging of glass bottles typically involves manual film rolling or manual use of packaging materials such as air column bags and gourd film, which consumes a lot of labor costs and is prone to errors. There is no automatic air column bag filling mechanism for glass bottles on the market. In order to save labor costs and ensure that glass bottles are not damaged due to human error during operation, there is an urgent need to develop an automated air column bag inflation mechanism. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides an integrated air column bag inflation and tearing mechanism. This mechanism, combined with a robotic arm for transport, automatically loads glass bottles into air column bags and reliably tears and inflates the bags, saving labor costs and improving packaging efficiency.

[0004] An integrated air column bag inflation and tearing mechanism, characterized in that it comprises:

[0005] Bottle conveyor line, which is equipped with a circulating conveyor belt;

[0006] A vertical frame includes a vertical plate, on which a bag-tearing station area, a bag-pulling station area, and an inflation station area are sequentially arranged along the length direction.

[0007] An air column bag roll placement rack includes a central rotating shaft and several guide clamps, wherein the central rotating shaft is arranged vertically.

[0008] A guide rod is arranged horizontally along the length of the upper area of ​​the front face of the upright plate. The end of the guide rod is provided with air holes at intervals. The end of the guide rod is provided with an axially recessed central blind hole. The central blind hole connects to all the air holes. The outer end of the central blind hole is connected to an air inlet pipe through an air connector.

[0009] Three sets of guiding bag feeding mechanisms are arranged independently and at intervals. Each set of guiding bag feeding mechanisms includes a drive motor, an upper synchronous pulley set, and a lower synchronous pulley set. Each upper synchronous pulley set includes several forward-protruding upper guide rollers, a rear first transmission wheel, and a transmission shaft. Each lower synchronous pulley set includes several forward-protruding lower guide rollers, a rear second transmission wheel, and a transmission shaft. The output shaft end of the drive motor meshes with a corresponding meshing gear on the driven shaft through a gear. A first synchronous pulley is sleeved on the output shaft, and a second synchronous pulley is sleeved on the driven shaft. The first synchronous pulley is directly or indirectly connected to all the first transmission wheels in the same set of guiding bag feeding mechanisms through a synchronous belt. The second synchronous pulley is directly or indirectly connected to all the second transmission wheels in the same set of guiding bag feeding mechanisms through a synchronous belt. The upper guide rollers in the same set of guiding bag feeding mechanisms are arranged on the upper part of the guide rod, and the lower guide rollers are arranged on the lower part of the guide rod.

[0010] The bag-pulling mechanism includes an inner end suction mechanism and an outer movable suction mechanism;

[0011] And a cutting knife;

[0012] A vertical frame is arranged on the inner side of the bottle conveyor line, with the uprights facing the bottle conveyor line. An air column bag roll placement rack is provided at the outer end of the starting end of the bottle conveyor line. The air column bag roll is sleeved on the central rotating shaft. After passing through the guide clamp, the air column bag is fed along the bottle conveyor line. The top of the air column bag is guided through the roll and sleeved on the guide rod. A tear-off opening is provided between adjacent air column bags. A set of guiding bag feeding mechanisms is respectively provided on the uprights of the tearing bag station area, the pulling bag station area, and the inflation station area.

[0013] An inner end suction mechanism is provided in the middle area of ​​the vertical plate corresponding to the bag-pulling station area in the height direction. Several suction cup mechanisms are provided around the front convex panel of the inner end suction mechanism. An outer side moving suction mechanism is provided at the front end of the bottle conveyor line corresponding to the bag-pulling station area. The outer side moving suction mechanism includes an inner and outer translation mechanism and a suction component. The inner and outer translation mechanism drives the suction component to move away from or towards the vertical plate.

[0014] The cutter is fixed at the end of the guide rod and cuts the conductive roll material corresponding to the air column bag after inflation is completed.

[0015] A first sensor is installed on the upright plate at the position between the bag-tearing station area and the bag-pulling station area. A second sensor is installed on the upright plate at the position between the bag-pulling station area and the inflation station area. A third sensor is installed on the upright plate at the rear end of the inflation station area. The first sensor is used to determine whether the bag-tearing action is completed. The second sensor, combined with the sensing state of the first sensor, is used to give a bag-tearing command or not to give a command. The third sensor is used to give an inflation command.

[0016] Its further features are:

[0017] The bottle conveying line also includes a conveying motor, a drive roller, a driven roller, and a conveying frame. The inner end of the conveying frame is fixed to the bottom of the upright plate. The drive roller and the driven roller are arranged at both ends of the conveying frame along its length. The circulating conveyor belt is fitted around the outer periphery of the assembly formed by the drive roller, the driven roller, and the conveying frame. The input end of the drive roller is also connected to the output shaft end of the conveying motor through a transmission structure.

[0018] The outer movable suction mechanism also includes a support base. The bottom of the support base is fixed to the outer side of the conveying frame at the corresponding position of the bag pulling station area. The support base is arranged vertically. The upper surface of the support base is fixed with the mounting base of the inner and outer translation mechanism. The output end of the inner and outer translation mechanism is connected to a vertical panel. The suction assembly is arranged on the vertical panel.

[0019] The suction assembly includes suction nozzle mechanisms on both sides of the upper part and suction cup mechanism at the lower part. The suction cup mechanism is also connected by guide posts, guide springs and vertical panels. The guide springs at the lower part enable the entire suction assembly to have an automatic adjustment dimension. After the suction cup mechanism of the front convex panel of the inner end suction mechanism adsorbs the inner air column body, the outer suction nozzle mechanism has an automatic adjustment dimension to adsorb the outer air column body. Then, it is pulled outward by the inner and outer translation mechanism to form a central inner cavity, which makes it easier for the robot to transfer the glass bottle into the central inner cavity.

[0020] After adopting the above technical solution, the guide roll of the air column bag passes through the guide rod. The upper and lower guide rollers of the bag feeding mechanism are arranged vertically to press the guide roll. The drive motor of the bag feeding mechanism drives the upper and lower guide rollers to rotate in both directions, causing the unfolded air column bag to move on the guide rod. When the guide roll moves to the second sensor, the drive motor in the tearing station area reverses and cooperates with the drive motor in the pulling station area to complete the tearing operation. The tear openings of the two sets of air column bags corresponding to the first sensor are broken. The first sensor senses that the tearing is complete. The inner suction mechanism of the pulling mechanism holds the inner air column body, and the outer moving suction mechanism holds the outer air column. The main body moves the outer air column body outward, forming a central cavity. The external robotic arm transfers the bottle and places it into the central cavity. Then, the drive motors in the bag-pulling and inflation stations move the air column bag to the inflation station. Air enters through the inflation hole of the guide rod and flows into the air column bag. Finally, the cutter cuts the guide roll of the air column bag, forming a cross-section that separates the air column bag from the guide rod, completing the entire process. Each of the three stations can start and stop independently without interfering with each other. Combined with the transfer by the robotic arm, the glass bottle is automatically loaded into the air column bag, and the air column bag is reliably torn and inflated, saving labor costs and improving packaging efficiency.

[0042] Its working principle is as follows: the guide roll of the air column bag passes through the guide rod. The upper and lower guide rollers of the bag feeding mechanism are arranged vertically to press the guide roll of material. The drive motor of the bag feeding mechanism drives the upper and lower guide rollers to rotate in both directions, causing the unfolded air column bag to move on the guide rod. When the guide roll of material moves to the second sensor, the drive motor in the tearing station area reverses and cooperates with the drive motor in the pulling station area to complete the tearing operation. The tear openings of the two sets of air column bags corresponding to the first sensor are broken. The first sensor senses that the tearing is complete. The inner suction mechanism of the pulling mechanism holds the inner air column body, and the outer moving suction mechanism holds the outer air column body. The body moves the outer air column body outward, forming a central cavity. The external robotic arm transfers the bottle and places it into the central cavity. Then, the drive motors in the bag-pulling and inflation stations move the air column bag to the inflation station. Air enters through the inflation hole of the guide rod and flows into the air column bag. Finally, the cutter cuts the guide roll of the air column bag, forming a cross-section that separates the air column bag from the guide rod, completing the entire process. Each of the three stations can start and stop independently without interfering with each other. Combined with the transfer by the robotic arm, the glass bottle is automatically loaded into the air column bag, and the air column bag is reliably torn and inflated, saving labor costs and improving packaging efficiency.
