[0026] In the existing bag-making production line, the nozzle feeding device feeds the nozzle into the bag body and welds and fixes the nozzle and the bag body. Feeding the nozzle into the bag body and welding and fixing the nozzle and the bag body are completed at the same workstation, which means that the two processes of feeding the nozzle into the bag body and welding and fixing the nozzle and the bag body cannot be carried out at the same time. There is always a situation where one process needs to wait, which reduces the efficiency of nozzle feeding and bag making.

[0027] Reference Figure 1-Figure 5A nozzle feeding device includes: a frame 10, two material-feeding manipulators 11 and a driving mechanism. The two material-feeding manipulators 11 can be slidably installed on the frame 10, and the material-feeding manipulators 11 have a first working position and a second working position; the driving mechanism drives the material-feeding manipulator 11 to move between the first working position and the second working position, and the manipulator has a first clamping finger for clamping a suction nozzle 12; the first working position and the second working position are respectively used to feed the suction nozzle 12 into the bag body and weld and fix the suction nozzle 12 to the bag body.

[0028] The specific actions of the above embodiment are as follows: in the first working position, after the material picking robot 11 picks up the suction nozzle 12, it sends the suction nozzle 12 into the bag body on the bag making production line. At this time, the material picking robot 11 continues to clamp the suction nozzle 12, and then the bag making production line moves forward. After the material picking robot 11 clamps the suction nozzle 12 and moves with the bag making production line to the second working position, the bag body and the suction nozzle 12 are welded and fixed. After the suction nozzle 12 is welded and fixed in the bag body, the material picking robot 11 releases the suction nozzle 12, and then the material picking robot 11 moves in the opposite direction and returns to the first working position; when one of the material picking robots 11 is located in the second working position, the other material picking robot 11 is located in the first working position, and the two material picking robots 11 move relative to each other in a cross-direction, so that the two processes of sending the suction nozzle 12 into the bag body and welding the suction nozzle 12 to the bag body are carried out simultaneously without waiting, which can greatly improve the nozzle feeding efficiency and meet the needs of the automatic bag making production line.

[0029] Of course, those skilled in the art will appreciate that the number of the material-retrieving robots 11 may also be adjusted according to the efficiency of the bag-making production line. In order to meet a faster bag-making cycle, three or more material-retrieving robots may be provided.

[0030] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the driving mechanism includes an annular conveyor belt 20 and a motor 13, the motor 13 is arranged on the frame 10, the annular conveyor belt 20 is rotatably arranged on the frame 10, two material-grabbing manipulators 11 are installed on the annular conveyor belt 20 at intervals, the two material-grabbing manipulators 11 are evenly distributed on the annular conveyor belt 20, and the motor 13 drives the annular conveyor belt 20 to rotate; the motor 13 can drive the material-grabbing manipulator 11 to slide back and forth in forward and reverse rotation. The structure of the above embodiment is very simple, the two material-grabbing manipulators 11 are fixed on the annular conveyor belt 20, and the coordinated movement of the two is guaranteed by the annular conveyor belt 20, and the synchronization is very good. The annular conveyor belt 20 can adopt a synchronous belt or an ordinary belt.

[0031] Of course, those skilled in the art will appreciate that the two retrieving robots 11 may be mounted on the frame 10 in other ways. For example, a track may be provided on the frame 10, and the retrieving robot 11 may be slidably mounted on the track, and then the retrieving robot 11 may be driven to slide relative to the frame 10 by a pneumatic cylinder or an electric cylinder. By controlling the coordination of the two pneumatic cylinders or electric cylinders, the effect of controlling the coordinated work of the retrieving robot 11 may be achieved.

[0032] like Figure 4 As shown, in some embodiments of the present invention, the material-retrieving manipulator 11 includes a first linear drive component 14 and a first sliding plate 15. The first linear drive mechanism is implemented by a cylinder. The first linear drive component 14 is installed on the endless conveyor belt 20. The first sliding plate 15 is fixedly connected to the output end of the first linear drive component 14, and the first clamping finger is installed on the first sliding plate 15. The first clamping finger clamps the suction nozzle 12, and then drives the suction nozzle 12 to move laterally through the first linear drive component 14, so as to deliver the suction nozzle 12 into the bag body. The above-mentioned implementation method of the material-retrieving manipulator 11 is simple in structure and stable and reliable in operation. In this embodiment, the first linear drive component 14 and the first sliding plate 15 are implemented by a slide cylinder.

[0033] Of course, the first linear drive mechanism can also be implemented in other ways, for example, it can be driven by a hydraulic cylinder or an electric cylinder, which can also achieve the same technical effect.

[0034] like Figure 5 As shown, in some embodiments of the present invention, a bag opening assembly 16 for opening the film at the bag opening is provided on the frame 10. The bag opening assembly 16 corresponds to the first working position of the material taking manipulator 11. After the bag opening assembly 16 opens the bag, the material taking manipulator 11 delivers the suction nozzle 12 into the bag.

[0035] Of course, those skilled in the art will appreciate that, according to actual needs, the bag opening assembly 16 may also be disposed on a bag making production line.

[0036] like Figure 5 As shown, in some embodiments of the present invention, the bag opening component 16 includes a suction cup 28, which is installed on the frame 10 in a liftable manner; the suction cup 28 is connected to a negative pressure source so as to generate an adsorption force through negative pressure. The suction cup 28 can be driven to rise and fall by a cylinder or an electric cylinder. There are two suction cups 28, which are respectively located on the upper and lower sides of the bag body. The suction cups 28 adsorb the two sides of the bag body, and then the two suction cups 28 are relatively far away from each other, so that the bag body can be opened. The structure is simple and practical.

[0037] like Figure 5As shown, in some embodiments of the present invention, a heat sealing assembly 17 for heat-welding the suction nozzle 12 to the bag body is provided on the frame 10. The heat sealing assembly 17 corresponds to the second working position of the material taking manipulator 11. When the suction nozzle 12 reaches the position of the heat sealing assembly 17, the heat sealing assembly 17 works to weld the suction nozzle 12 to the bag body.

[0038] Of course, those skilled in the art will appreciate that, according to actual needs, the heat sealing assembly 17 can also be disposed on a bag-making production line, and can also achieve welding and fixing of the nozzle 12 and the bag body.

[0039] like Figure 5 As shown, in some embodiments of the present invention, the heat sealing assembly 17 includes an upper mold 18 and a lower mold 19, and the upper mold 18 and the lower mold 19 can be relatively mounted on the frame 10. The upper mold 18 and the lower mold 19 have a heat source, which can be a resistance wire. The upper mold 18 and the lower mold 19 clamp the suction nozzle 12 and the bag body at the suction nozzle 12, and keep them for a set time, so that the bag body and the suction nozzle 12 can be welded and fixed. The upper mold 18 and the lower mold 19 can be driven to rise and fall by a cylinder or an electric cylinder.

[0040] In some embodiments of the present invention, a turntable 21 is rotatably provided on the frame 10, and at least two stations 22 for placing the suction nozzle 12 are provided on the turntable 21. A sleeve 29 is provided on the station 22, and the suction nozzle 12 can be partially inserted into the sleeve 29 for positioning. The station 22 rotates with the turntable 21 and can be docked with the material-retrieving manipulator 11 one by one. By providing at least two stations 22, the suction nozzle 12 can enter the turntable 21 and move out of the turntable 21 at the same time, without waiting for a beat, thereby improving work efficiency.

[0041] like Figure 1As shown, in order to improve work efficiency, in some embodiments of the present invention, a vibration plate 24 for outputting the suction nozzles 12 one by one in an orderly manner is provided on the frame 10, and the output end of the vibration plate 24 is docked with the work station 22. The vibration plate 24 can adopt existing mature technology, which will not be described in detail here. The suction nozzle 12 output by the vibration plate 24 is docked with the work station 22, and the suction nozzle 12 can be moved to the work station 22 manually, or by arranging a material transfer robot 25 on the frame 10 for moving the suction nozzle 12 at the output end of the vibration plate 24 to the work station 22, the material transfer robot 25 includes a second linear drive component 26, a second sliding plate 27 and a second clamping finger, the second linear drive component 26 is installed on the frame 10, the second sliding plate 27 is fixedly connected to the output end of the second linear drive component 26, and the second clamping finger is installed on the second sliding plate 27. The second clamping finger can clamp and release the suction nozzle 12. After the second clamping finger clamps the suction nozzle 12 from the output end of the vibration plate 24, the second linear drive component 26 moves to drive the suction nozzle 12 to move toward the work station 22 until the suction nozzle 12 is inserted into the sleeve 29. The second clamping finger is released, and the second linear drive component 26 moves in the opposite direction, driving the second clamping finger to move toward the output end of the vibration plate 24 to continue clamping the suction nozzle 12; the work station 22 of the turntable 21 will rotate one position after receiving the suction nozzle 12, so that the next sleeve 29 that has not received the suction nozzle 12 can be connected to the output end of the vibration plate 24, and the work is cyclical.

[0042] The first clamping finger and the second clamping finger both include two clamping finger bodies 30 , and the two clamping finger bodies 30 can rotate relative to each other so as to clamp and place the suction nozzle 12 . The second linear drive component 26 can be implemented by a pneumatic cylinder or an electric cylinder.

[0043] like Figure 3 As shown, in some embodiments of the present invention, in order to further correct the angle of the suction nozzle 12, a positioning assembly is provided on the frame 10 at the output end of the vibration plate 24, the positioning assembly includes a lower positioning block 32, an upper positioning block 31 and a baffle 33, the lower positioning block 32 is installed on the frame 10, a lower positioning groove is provided on the upper part of the lower positioning block 32, the upper positioning block 31 can be installed on the frame 10 in a liftable manner, an upper positioning groove is provided on the lower part of the upper positioning block 31, the baffle 33 can be installed on the frame 10 in a liftable manner, and the baffle 33 is located between the lower positioning block 32 and the turntable 21; the upper positioning groove and the lower positioning groove match the suction nozzle 12, so that the suction nozzle 12 can only enter between the upper positioning block 31 and the lower positioning block 32 at a specific angle, so as to achieve the purpose of correcting the angle, the baffle 33 is in front of the suction nozzle 12, and the suction nozzle 12 is limited, so that the second clamping finger is clamped at the set position of the suction nozzle 12, so as to facilitate the subsequent process flow.

[0044] like Figure 3As shown, in some embodiments of the present invention, in order to improve the working efficiency of welding and fixing, a preheating component 23 for heating the suction nozzle 12 located at the station 22 is provided on the frame 10, and three stations 22 are provided on the turntable 21. The turntable rotates 120 degrees each time, and the three stations 22 correspond to the vibration plate 24, the preheating component 23 and the bag opening component 16 respectively. After the suction nozzle 12 on the vibration plate 24 is moved to the station 22 of the turntable 21 by the material transfer manipulator 25, the turntable 21 rotates one station 22, and the suction nozzle 12 moves to the preheating component 23. The preheating component 23 heats the suction nozzle 12 to the set temperature, and then The turntable 21 rotates one station 22 again, and the preheated suction nozzle 12 reaches the bag opening component 16. At this time, the bag opening component 16 opens the bag body on the bag making production line, and the material picking robot 11 clamps the suction nozzle 12 and moves it into the bag body. Then the turntable 21 continues to rotate one station 22, continues to receive the suction nozzle 12, and the material picking robot 11 keeps clamping the suction nozzle 12 and follows the bag making production line to move to the second working position. After the suction nozzle 12 is welded and fixed in the bag body, the material picking robot 11 releases the suction nozzle 12, and then the material picking robot 11 moves in the opposite direction, returns to the first working position, and continues to feed the suction nozzle 12 into the bag body.

[0045] Of course, the number of the stations 22 can also be set to four, and the turntable 21 rotates 90 degrees each time, which can also achieve the same technical effect. Among them, the preheating component 23 can adopt the same implementation method as the heat sealing component 17.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
