Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, and in particular to a fully automatic sampling and packaging machine. Background Technology

[0002] Currently, the sampling process in packaging machines mainly relies on manual operation, including manual sampling, bagging, vacuuming, and sealing. This traditional method is not only labor-intensive but also exposes employees to dusty environments for extended periods, posing a significant health hazard.

This production line not only allows small granular materials to be filled into the inner film bag of the packaged bag and heat-sealed, but also automatically inserts the inner film bag opening into the outer woven bag opening. However, on the one hand, this production line is mainly used for packaging packaged inner and outer bags, and the various mechanisms are relatively dispersed and lack effective integration, resulting in an overall layout that is not compact, low space utilization, and a large footprint.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1-4 As shown: A fully automatic sampling and packaging machine includes a frame 1 and a bag-filling mechanism 2, a coding mechanism 3, a bag-picking mechanism 4, a bag-opening mechanism 5, a bag-clamping mechanism 6, a walking assembly 7, a heat-sealing mechanism 8, a cap-opening mechanism 9, a carrier 10, a carrier drive mechanism 11, and a conveying mechanism, all mounted on the frame 1. The bag-filling mechanism 2 and the cap-opening mechanism 9 are mounted on the top of the frame 1, and the top of the frame 1 also has a discharge port 14; the remaining mechanisms are installed within the cavity of the frame 1.

[0042] Specifically, the bag-picking mechanism 4 is located below the bagging mechanism 2, used to pick up the bottommost material bag 16 at the bagging mechanism 2 and rotate it 90° to be opposite to the bag-opening mechanism 5. The coding mechanism 3 is located on one side of the bag-picking mechanism 4, used to move to the bottom of the bagging mechanism 2 to complete the coding process of the bottommost material bag 16 in the bagging mechanism 2. The bag-opening mechanism 5 and the bag-clamping mechanism 6 are combined and installed on the sealing cover plate 13. The bag-opening mechanism 5 is used to cooperate with the bag-picking mechanism 4 to open the bag mouth of the material bag 16, and the bag-clamping mechanism 6 is used to clamp the material bag 16 after the bag mouth is opened. The sealing cover plate 13 is installed on the traveling assembly 7, which is installed on the inner wall of the frame 1. The traveling assembly 7 drives the bag-opening mechanism 5 and the bag-clamping mechanism 6 to move laterally to the bottom of the discharge port 14, and deliver the discharged material bag 16 to the heat sealing station and above the carrier 10. The heat-sealing mechanism 8 is capable of longitudinal movement, and its open heat-sealing box 81 can cooperate with the sealing cover 13 to form a sealed chamber. The carrier 10 is located below the opening mechanism 9, which is used to grab the top cover 101 on the carrier 10 so that the filled material bag 16 can fall into the carrier 10. The carrier 10 is sent to the conveying mechanism via the carrier drive mechanism 11. The conveying mechanism is used to send the carrier 10 and the material bag 16 inside the carrier 10 to other positions, and also to return the empty carrier after the material bag 16 has been removed to its original position.

[0043] This embodiment, by rationally arranging the positions of various mechanisms, makes full use of the top and internal space of the frame 1, enabling all mechanisms to operate in an orderly manner within the frame 1. The compact layout greatly improves space utilization and saves site area. At the same time, it also realizes a fully automated process for the material bag 16 from bag taking, filling, sealing to conveying, which greatly improves work efficiency.

[0044] This embodiment combines the bag-opening mechanism 5 and the bag-clamping mechanism 6, which are then mounted together on the sealing cover 13 and fixed to the traveling assembly 7. The overall structure is compact. The traveling assembly 7 enables a fully automated process for filling, heat-sealing, and conveying the material bag 16 to the carrier. Furthermore, the sealing cover 13, in conjunction with the heat-sealing box 81 of the heat-sealing mechanism 8, forms a sealed chamber, effectively sealing and vacuuming the inside of the material bag 16. This design effectively improves work efficiency, ensures a highly efficient, stable, and precise packaging process, and optimizes the spatial layout, reducing the area occupied by the equipment.

[0045] The following is a detailed explanation of the structure of each institution:

[0046] In this embodiment, the entire frame 1 can be designed as a sealed or semi-sealed type, for example, all mechanisms operate inside the cavity and are sealed around the perimeter by plates to reduce noise and dust.

[0047] In this embodiment, the bagging mechanism 2 includes a material tray installed on the top of the frame 1. Material bags 16 are manually stacked and placed in the material tray. The bottom surface of the material tray is open, and the frame 1 also has an opening at a position corresponding to the bottom surface of the material tray, to facilitate coding by the coding mechanism 3 and bag retrieval by the bag-picking mechanism 4. In this embodiment, the material bag 16 is preferably an aluminum foil bag.

[0048] In this embodiment, the coding mechanism 3 is located on one side of the frame 1 and can move horizontally or vertically downwards towards the bottom of the material tray to code the material bags 16 located at the bottom of the material tray. Furthermore, the coding mechanism 3 is offset from the bag-picking mechanism 4; for example, the coding mechanism 3 is designed to move vertically to a corner of the material tray for coding. Since the coding device and the vertical movement drive mechanism of the coding mechanism 3 are conventional technologies, they will not be described in detail here.

[0049] like Figure 5 As shown: In this embodiment, the bag-picking mechanism 4 includes a bag-picking body 41, a bag-picking cylinder 42, and a tilting cylinder 43. The piston rod end of the bag-picking cylinder 42 is connected to the bag-picking body 41, and is used to drive the bag-picking body 41 to extend towards the bottommost material bag 16. The bag-picking body 41 is a frame or plate structure, and multiple bag-picking suction cups 44 are installed on the bag-picking body 41. The bag-picking suction cups 44 are vacuum suction cups. The bag-picking cylinder 42 is mounted on the tilting cylinder 43, and the tilting cylinder 43 is fixed on the frame 1. The piston rod end of the tilting cylinder 43 is connected to the cylinder body of the bag-picking cylinder 42. Through the action of the tilting cylinder 43, the bag-picking cylinder 42 and the bag-picking body 41 that adsorbs the material bag 16 are driven to rotate 90 degrees, thereby turning the material bag 16 from a horizontal state to a vertical state.

[0050] In this embodiment, the bag opening mechanism 5 includes a bag opening body 51 and a lifting cylinder 52 for controlling the up-and-down movement of the bag opening body 51. The bag opening body 51 has multiple bag opening suction cups 53 connected to the end facing the bag-taking body 41 that absorbs the material bag 16. The piston rod of the lifting cylinder 52 is connected to the bag opening body 51 to drive the bag opening body 51 to move up and down. The lifting cylinder 52 is fixed to the sealing cover plate 13 via a cylinder connecting seat. It is understood that the structure of the bag opening body 51 can be flexibly designed according to requirements.

[0051] In this embodiment, the bag clamping mechanism 6 includes bag opening clamps 61 disposed on both sides of the bag opening body 51 and clamping tension cylinders 62 for adjusting the distance between the two bag opening clamps 61. Preferably, the bag opening clamps 61 are pneumatic clamps, capable of opening and closing under the action of their own cylinders, so as to clamp or release the material bag 16. The bag opening clamps 61 are integrally connected to the piston rod end of the clamping tension cylinders 62. The distance between the two bag opening clamps 61 is adjusted by the extension and retraction of their respective clamping tension cylinders 62, thereby achieving the stretching and tightening of the bag opening of the material bag 16. In this embodiment, the two bag opening clamps 61 are symmetrically connected to both sides of the bag opening body 51 through connecting seats 63 and extend forward along both sides. The bag opening suction cups 53 on the bag opening body 51 are located between the two bag opening clamps 61. In this way, when the bag-removing suction cup 44 and the bag-opening suction cup 53 respectively adsorb the two sides of the material bag 16 and open the bag opening, the bag opening clamp 61 will accurately clamp the edge of the bag opening to ensure that the bag opening remains open.

[0052] In this embodiment, the sealing cover 13 is connected to the traveling assembly 7 and can be moved laterally by the traveling assembly 7. The traveling assembly 7 can be a screw drive, belt drive, or chain drive mechanism. For example, when a chain drive mechanism is used, it includes a guide rail on the inner wall of the frame 1, a guide slider that can move on the guide rail, a drive motor, at least one sprocket, and a horizontally arranged chain; wherein the sealing cover 13 is fixed to the guide slider. The drive motor is connected to the sprocket shaft via a gearbox or reducer, driving the main sprocket to rotate. The main sprocket and the driven sprocket mesh with the chain. The chain connects to the guide slider, and during movement, the chain drives the guide slider to move horizontally on the guide rail, thereby causing the sealing cover 13 to move laterally. It is understood that the length of the guide rail is sufficient to allow the traveling assembly 7 to move the sealing cover 13 to various required work positions.

[0053] like Figure 6As shown: In this embodiment, the heat sealing mechanism 8 includes a heat sealing box 81 and a box driving mechanism for driving the longitudinal movement of the heat sealing box 81. The heat sealing box 81 is designed as an open structure on the side facing the sealing cover 13. The sealing cover 13 is designed with a cavity structure, within which the bag opening mechanism 5 and the bag clamping mechanism 6 are fixed. The side of the sealing cover 13 forming the cavity is in contact with the heat sealing box 81 to form a sealed chamber. The bag opening mechanism 5, the bag clamping mechanism 6, and the material bag 16 are all enclosed within the sealed chamber. It is understood that the heat sealing box 81 is connected to a vacuum device to form a vacuum chamber. A support base 82 is mounted on the bottom panel of the frame 1, and the heat sealing mechanism 8 is mounted on the support base 82. The housing drive mechanism includes a linear guide rail 83 mounted on the upper surface of the support base 82, a slider movable on the linear guide rail 83, and a drive unit for controlling the movement of the heat sealing housing 81; wherein the heat sealing housing 81 is fixed on the slider, and the drive unit can be a motor screw drive, a motor belt drive, or a motor chain drive. Since the above-mentioned drive methods are existing technologies, they will not be described in detail here.

[0054] like Figure 7 and Figure 8 As shown: In this embodiment, a carrier 10 is provided on the side of the heat-sealing mechanism 8 away from the bag-taking mechanism 4, and a cover-opening mechanism 9 is provided above the carrier 10. Since the carrier 10 has a top cover 101, the cover-opening mechanism 9 needs to open the top cover 101 so that the bag-clamping mechanism 6 can release the heat-sealed material bag 16 into the carrier for transport. The cover-opening mechanism 9 is installed on the top of the frame 1 and includes a cover-opening cylinder 91. The cover-opening cylinder 91 is fixed to the top of the frame 1 by a connecting component provided on the outer surface of the top plate of the frame 1, and the top of the frame 1 has a hole, through which the cover-opening cylinder 91 can extend into the frame 1, corresponding to the position of the carrier 10. The piston end of the cover-opening cylinder 91 is provided with a gripping part for gripping the top cover 101 of the carrier. In this embodiment, the gripping part can be a suction cup, a magnet, or a gripper, etc. The cover-opening cylinder 91 extends its piston rod downward to grip the top cover 101 on the carrier and lifts it upward to the initial position.

[0055] In this embodiment, the conveying mechanism is preferably a pneumatic conveying mechanism, specifically including a pneumatic conveying channel 12, which is connected to an external air source device via a pipeline. An output port 17 is provided on the top plate of the frame 1, and the pneumatic conveying channel 12 is connected to the output port 17. The carrier 10 is preferably designed as a cylinder so that the carrier 10 can be output from the output port 17. When the carrier driving mechanism 11 pushes the carrier 10 containing the material bag 16 into the pneumatic conveying channel 12, the air source device provides a stable high-pressure airflow to push the carrier from the pneumatic conveying channel 12 to other positions. After the carrier 10 delivers the material bag 16 to the designated position, it is then transported back to the starting position through the pneumatic conveying channel 12, and then the carrier driving mechanism 11 brings the carrier 10 back to the initial position.

[0056] In this embodiment, the vehicle driving mechanism 11 is preferably a vehicle driving cylinder 111, which is located within the space enclosed by the support seat 82 at the lower end of the heat sealing mechanism 8, thus greatly improving the structural compactness. Since the vehicle driving cylinder 111 needs to deliver the vehicle to the pneumatic conveying channel 12 and then retrieve it from the pneumatic conveying channel 12, this embodiment preferably provides a channel opening 121 on the side of the pneumatic conveying channel 12 facing the vehicle 10. The vehicle 10 is placed inside the vehicle container 112, and the vehicle container 112 is connected to a channel cover plate 113 for sealing the channel opening 121. The pneumatic conveying channel 12 is sealed by tightly fitting the channel opening 121. The piston end of the vehicle driving cylinder 111 is connected to the back of the channel cover plate 113, and the front of the channel cover plate 113 is connected to the vehicle container 112. The bottom surface of the vehicle container 112 is open to allow the vehicle to be output under the action of airflow. The base plate of the frame 1 has carrier guide rails 114 on both sides of the channel cover 113. The two sides of the channel cover 113 are slidably connected to the carrier guide rails 114 via sliders. When the carrier drive cylinder 111 pushes the channel cover 113 to move toward the pneumatic conveying channel 12, the channel cover 113 moves together with the carrier container 112. The carrier 10 is placed inside the carrier container 112, and the material bag 16 is placed inside the carrier 10, thus moving as a whole. After the channel cover 113 is in contact with the opening of the pneumatic conveying channel 12, both the channel cover 113 and the pneumatic conveying channel 12 are connected to the air source equipment through pipes, so that the carrier in the carrier container 112 moves upward under high-pressure airflow and exits the frame 1, taking out the material bag 16 from the carrier 10. Then, the empty vehicle is sent from the output port 17 of the frame 1 to the pneumatic conveying channel 12. The vehicle 10 is transported in reverse under the airflow to the vehicle container 112, and together with the channel cover 113, it is brought back to the initial position by the vehicle drive cylinder 111.

[0057] In this embodiment, when the material is powder, a feeding dust removal mechanism 15 can also be provided. Specifically, the feeding dust removal mechanism 15 is installed in the feeding port 14 at the top of the frame 1. When the walking component 7 drives the bag clamping mechanism 6 to move laterally to below the feeding port 14, the powder will fall into the material bag 16 through the feeding dust removal mechanism 15 to absorb the dust raised by the powder during the feeding process.

[0058] The entire workflow of this embodiment includes the following steps:

[0059] S101: The coding mechanism 3 moves to the bottom of the bagging mechanism 2 to complete the coding process of the bottom material bag 16 in the bagging mechanism 2.

[0060] S102: The bag-picking body 41 of the bag-picking mechanism 4, driven by the bag-picking cylinder 42, presses upward from the initial position against the surface of the bottom material bag 16 to complete the adsorption and bag picking; after picking the bag, the bag-picking body 41 drives the material bag 16 back to the initial position, and then the flipping cylinder 43 drives the bag-picking body 41, the bag-picking cylinder 42 and the material bag 16 to complete a 90-degree rotation, so that the material bag 16 rotates from a horizontal position to a vertical position.

[0061] S103: After being flipped, the bag-picking cylinder 42 drives the bag-picking body 41 of the material bag 16 to extend towards the bag-opening mechanism 5. The walking component 7 drives the bag-opening mechanism 5 together with the bag-clamping mechanism 6 to move towards the material bag 16. The bag-opening body 51 adsorbs the other side of the material bag 16 through the bag-opening suction cup 53, so that the bag-picking suction cup and the bag-opening suction cup 53 adsorb both sides of the material bag 16. The bag-picking suction cup does not move, and the walking component 7 drives the bag-opening suction cup 53 to move in the opposite direction to open the bag opening of the material bag 16.

[0062] S104: The bag clamping mechanism 6 located on both sides of the bag opening suction cup 53 clamps the edge of the opened bag opening. After the bag opening is clamped, the bag taking suction cup and bag opening suction cup 53 located on both sides of the material bag 16 break the vacuum and detach from the material bag 16.

[0063] S105: The bag clamping mechanism 6 drives the material bag 16 to move laterally to below the discharge port 14 through the walking component 7. The lifting cylinder 52 drives the bag opening mechanism 5 and the bag clamping mechanism 6 to move upward as a whole. The material bag 16 clamped by the bag mouth clamp 61 moves upward from the initial position to the discharge port 14, and the discharge port enters the bag mouth for material discharge.

[0064] S106: After the material is unloaded, the bag opening mechanism 5 and the bag clamping mechanism 6 return to the initial position, and the bag mouth clamp 61 stretches and tightens the bag mouth through the clamp stretching cylinder 62.

[0065] S107: The walking component 7 drives the sealing cover plate 13 to the heat sealing station. The heat sealing box 81 of the heat sealing mechanism 8 moves longitudinally from its original position to the sealing cover plate 13 through the box driving mechanism. After it is in contact with the sealing cover plate 13, a sealing chamber is formed. The sealing chamber is then evacuated so that the heat sealing mechanism 8 completes the heat sealing process on the bag opening in the vacuum sealing chamber.

[0066] S108: After the heat sealing of the bag mouth of the material bag 16 is completed, the heat sealing box 81 is disengaged from the sealing cover 13 by the box drive mechanism and returns to its original position.

[0067] S109: The opening mechanism 9 grabs the top cover 101 on the vehicle from the initial position downwards and lifts it upwards to the initial position;

[0068] S110: After the walking assembly 7 moves the material bag 16 above the carrier, the bag clamp 61 of the bag clamping mechanism 6 releases the material bag 16, causing the material bag 16 to fall into the carrier, and the carrier is located inside the carrier container 112.

[0069] S111: The carrier container 112, together with the channel cover 113, is pushed to the pneumatic conveying channel 12 by the carrier drive cylinder 111. The channel cover 113 is sealed to the opening of the pneumatic conveying channel 12. The carrier and the material bag 16 inside the carrier are conveyed to other locations through the pneumatic conveying channel 12.

[0070] S112: After the carrier delivers the material bag 16 to the designated position, it is then transported back to the starting position via the pneumatic conveying channel 12; the carrier drive cylinder 111 brings the carrier back to the position where the material bag 16 is received.

[0071] S113: The cycle repeats thereafter.
