[0001] The invention relates to the field of packaging bag production, and in particular to a soft packaging bag collecting device. Background Art

[0002] In the mechanical packaging industry, the automation development of self-priming bag nozzle welding machines and filling equipment is becoming increasingly concentrated to improve production efficiency and reduce labor costs. The self-priming bag nozzle welding machine has evolved from the original single-head sealing to multi-head sealing to improve production efficiency. However, when filling the self-priming bags, the self-priming bags are usually placed on the trough manually, and then the trough filled with self-priming bags is moved to the filling production line as a whole. Usually, the filling production line is very fast, and a large number of people are required to place the self-priming bags manually, which takes up a lot of time and becomes a bottleneck in automated production.

[0003] At present, some people have proposed an automatic material feeding trough device for a welding nozzle machine on the market (application number 201410111416.0), which discloses "comprising a frame (1), the frame (1) being provided with a workbench (3) for placing a material trough (2), characterized in that the workbench (3) is provided with a material dropping guide device (4) fixedly connected thereto for guiding the material trough (2) and sliding down onto the workbench (3) by its own weight, the workbench (3) is also provided with a filling station (5) located at the side of the material dropping position at the bottom of the material dropping guide device (4) for filling the material trough (2) with a self-priming bag (8), the bottom of the workbench (3) is provided with a material trough pushing device (7) for pushing the material trough (2) sliding onto the workbench (3) to the filling station (5) and the outside of the workbench (3) in turn...".

[0028] like Figure 1-Figure 3As shown, the flexible packaging bag collecting device in this embodiment includes a frame 911, and the top of the frame 911 is a table 912. A filling port is provided at the position of the table 912 opposite to the bag discharging mechanism 8. A trough self-dropping frame 913 is provided in the middle of the table 912, and a trough feeding port 914 is provided on the top of the trough self-dropping frame 913. A pair of material dropping guide brackets 915 are provided at both ends of the trough feeding port 914, and a plurality of troughs 99 are stacked and placed in the material dropping guide brackets 915 and fall onto the table 912 in sequence by their own weight.

[0029] like Figure 4 As shown, a trough pushing assembly is provided inside the frame 911 , and the trough pushing assembly includes a fixing plate 916 fixed on the bottom surface of the table 912 and a first discharge unit and a second discharge unit respectively connected to the fixing plate 916 .

[0030] like Figure 5-Figure 7 As shown, the first discharge unit includes a first main slide 917, a first outer slide 918, a first main push cylinder 919 and a first auxiliary push cylinder 920, and the second discharge unit includes a second main slide 921, a second outer slide 922, a second main push cylinder 923 and a second auxiliary push cylinder 924.

[0031] A pair of slide rails 925 are connected to the bottom surface of the fixed plate 916 , the first main slide 917 and the first outer slide 918 are connected to the right half of the pair of slide rails 925 , and the second main slide 921 and the second outer slide 922 are connected to the left half of the pair of slide rails 925 .

[0032] Clamping mechanisms are provided at both ends of the first main slide plate 917 , the first outer row slide plate 918 , the second main slide plate 921 and the second outer row slide plate 922 .

[0033] The end of the first main thrust cylinder 919 is fixed to the right bottom surface of the fixed plate 916, the telescopic end of the first main thrust cylinder 919 is connected to the bottom surface of the first outer row of slide plates 918, the cylinder sleeve of the first auxiliary thrust cylinder 920 is fixed to the bottom surface of the first outer row of slide plates 918, and the telescopic end of the first auxiliary thrust cylinder 920 is connected to the bottom surface of the first main slide plate 917.

[0034] The end of the second main push cylinder 923 is fixed on the left bottom surface of the fixed plate 916, the telescopic end of the second main push cylinder 923 is connected to the bottom surface of the second outer row of slide plates 922, the cylinder sleeve of the second auxiliary push cylinder 924 is fixed on the bottom surface of the second outer row of slide plates 922, and the telescopic end of the second auxiliary push cylinder 924 is connected to the bottom surface of the second main slide plate 921.

[0035] like Figure 8As shown, the clamping mechanism includes a clamping connection seat 926 for fixing on the slide, and the clamping connection seat 926 is provided with a driving clamping gear shaft 927 and a driven clamping gear shaft 928 which are parallel to each other, and the driving clamping gear shaft 927 is provided with a driving gear 929, and the driven clamping gear shaft 928 is provided with a driven gear 930 meshing with the driving gear 929. The driving clamping gear shaft 927 and the driven clamping gear shaft 928 are also provided with a driving clamping claw 931 and a driven clamping claw 932 for clamping the material trough, which rotate synchronously with the driving gear 929 and the driven gear 930 respectively.

[0036] The clamping connection seat 926 is also fixedly connected to a clamping cylinder 933, and the output end of the clamping cylinder 933 is connected to a rack 934 that meshes with the driving gear 929 and is used to drive the driving gear 929 to rotate. When the clamping cylinder 933 is extended, the rack 934 drives the driving gear 929 to rotate forward, thereby driving the driven gear 930 to rotate. At the same time, the active clamping jaw 931 and the driven clamping jaw 932 rotate synchronously from a vertical position to a horizontal position to loosen the material trough 99.

[0037] When the output end of the clamping cylinder 933 drives the rack 934 to retract, the driving gear 929 reverses, and the active clamping jaw 931 and the driven clamping jaw 932 rotate synchronously from the horizontal position to the vertical position, thereby clamping the material trough 99. The rack 934, the driving gear 929 and the driven gear 930 are meshed with each other to ensure that the active clamping jaw 931 and the driven clamping jaw 932 are clamped or released synchronously, and can be opened horizontally to avoid interference with the bottom surface of the table 912 when sliding.

[0038] A plurality of avoidance grooves 935 are provided on the table 912 for the clamping jaws to reciprocate in when extending.

[0039] When the bag collecting device is working, the first discharge unit and the second discharge unit work alternately. There will be a trough falling from the trough self-dropping frame 913 in the middle of the table 912. First, the first auxiliary push cylinder 920 extends to push the first main slide 917 to the middle, and then the clamping mechanisms at both ends of the first main slide 917 clamp the trough. Then, the first auxiliary push cylinder 920 drives the first main slide 917 to drive the trough to move to the filling port, and the clamping mechanism of the first main slide 917 is released. The first outer row slide 918 moves to the middle to the position of the trough, and the clamping mechanism on it also clamps the trough. After the trough is filled, the first outer row slide 918 moves outward to drive the trough to the discharge area, and the operator can take the trough away, forming an automated material collection process.

[0040] The working process of the second discharge unit is similar and will not be elaborated on.

[0041] It can be preferred that: it also includes a material trough pushing mechanism, which is arranged on the other side of the table 912 opposite to the loading port position, and the material trough pushing mechanism includes a pushing block 937 and a pushing block cylinder 938 driving the pushing block 937. When the material trough 99 is moved to the loading port 936 position, the pushing block 937 pushes the material trough 99 forward and presses it tightly against the side wall of the loading port 936 to prevent the material trough 99 from axial displacement during the material collection process.

[0042] The present invention is not limited to the above embodiments. The technical solutions of the above embodiments of the present invention can be cross-combined with each other to form new technical solutions. In addition, all technical solutions formed by equivalent replacement fall within the protection scope required by the present invention.
