Description

Technical Field

[0001] The utility model relates to the technical field of filling, in particular to an automatic bottle filling system for laundry detergent. Background Art

[0002] Filling machines are commonly used liquid packaging machines. Bottles of bottled laundry detergent are mostly irregular shapes with a handle on one side. At present, the filling process of laundry detergent is that the staff manually places the bottles and then the filling machine performs quantitative filling. The degree of automation is not high, the workload is large, and the labor cost is high. When filling the bottles, the existing filling machines clamp the bottle body with a cylinder to fix the bottle. Since most bottles are plastic bottles, the bottle body is made of soft plastic material. When positioning, the bottle body is deformed, causing the bottle mouth to tilt easily. Secondly, since laundry detergent is a viscous liquid, the laundry detergent adhered to the filling head drips during filling. Once it drips onto the bottle body or the conveyor belt, it is more troublesome to clean. Utility Model Content

[0026] As shown in the accompanying drawings, the utility model comprises an automatic bottle loading device 100 and a filling device 200 located on both sides of the discharge end of the automatic bottle loading device 100.

[0027] The automatic bottle loading device 100 comprises a hopper 1 and a loading belt conveyor 2 for sequentially taking out bottles in the hopper 1. A pair of unloading cylinders 3 are arranged on both sides of the loading belt conveyor 2 near the discharge end in a front-to-back staggered manner, and a receiving guide chute 4 is arranged on the loading belt conveyor 2 on the side opposite to the unloading cylinder 3.

[0028] The filling device 200 includes a first belt conveyor 20 and a filling machine 21 located on one side of the first belt conveyor 20. The feeding end of the first belt conveyor 20 is located below the discharging end of the receiving guide chute 4.

[0029] The filling machine 21 includes a filling lifting seat 23, a bottle mouth clamping cylinder 24, a filling head 25 and a filling head lifting cylinder 26. The bottle mouth clamping cylinder 24 is installed at the bottom of the lifting plate of the filling lifting seat 23, and the filling head lifting cylinder 26 is installed at the top of the lifting plate of the filling lifting seat 23 and drives the filling head 25 to move up and down.

[0030] Preferably, the feeding belt conveyor 2 is installed on the hopper 1 in an inclined state, and a plurality of partitions 6 are provided on the conveying belt of the feeding belt conveyor 2 along the conveying direction.

[0031] Furthermore, a material baffle plate 7 is provided above the feeding belt conveyor 2 near the feeding end. The material baffle plate 7 is hinged to the frame of the feeding belt conveyor 2 through a rotating shaft, and a torsion spring is provided on the rotating shaft.

[0032] Furthermore, a photoelectric sensor 8 for detecting bottles is provided on the feeding belt conveyor 2 located in front of the unloading cylinder 3 .

[0033] Preferably, the material receiving guide chute 4 is formed by splicing an inclined section 9 and a vertical section 10, a bottle outlet is provided on one side of the vertical section 10, and a bottle blocking cylinder 11 is provided on one side of the bottle outlet.

[0034] Preferably, the filling lifting seat 23 is a manual screw lifting seat, a mounting seat is provided on the top of the lifting plate of the manual screw lifting seat, a vertical slide is provided on one side of the mounting seat, the filling head 25 is installed on the slider of the vertical slide, and the filling head lifting cylinder 26 is fixed on the top of the mounting seat and drives the slider of the vertical slide to move up and down.

[0035] Furthermore, adjustable protective plates 50 are provided on both sides of the first belt conveyor 20 .

[0036] Preferably, both jaws of the bottle mouth clamping cylinder 24 are provided with a V-shaped bottle mouth positioning plate 27, which has an adjustment long hole, and the V-shaped bottle mouth positioning plate 27 is fixed to the jaws of the bottle mouth clamping cylinder 24 by a locking screw.

[0037] Furthermore, a receiving plate 28 is provided above the clamping jaws of the bottle mouth clamping cylinder 24, and an adsorption sponge layer is provided on the receiving plate 28. One end of the receiving plate 28 is hinged to the bottom of the cylinder body of the bottle mouth clamping cylinder 24 through a connecting rod, and a push rod 29 hinged to the connecting rod is provided on the clamping jaws of the bottle mouth clamping cylinder 24.

[0038] The working mode of the automatic bottle loading device 100 is as follows: the material bottle is a flat irregular container with a handle on one side. The material bottle is put into the hopper 1, and the material bottle is taken out in sequence by the loading belt conveyor 2 during transportation. In this case, the height of the partition 6 is not higher than the thickness of the material bottle. The optimal height of the partition 6 is the same as the thickness of the material bottle to prevent two material bottles from being stacked and transported forward. The spacing between two adjacent partitions 6 matches the width of the material bottle, but is not greater than the height of the material bottle, ensuring that the material bottle can be smoothly placed on the conveyor belt between the two partitions 6.

[0039] When the bottle is moved and transported to the position of the unloading cylinder 3 in the front, the corresponding photoelectric sensor 8 detects the direction of the bottle mouth of the bottle. If the bottle mouth is facing the direction of the unloading cylinder 3, the corresponding unloading cylinder 3 starts to push the bottle into the corresponding material receiving guide chute 4. The photoelectric sensor 8 located on the rear side only needs to detect that there is a bottle passing through, and the corresponding unloading cylinder 3 will push the bottle into the corresponding material receiving guide chute 4. After the bottle falls from the material receiving guide chute 4, it can maintain an upright state with the bottle mouth facing upward.

[0040] In this case, there is a gap between the baffle plate 7 and the partition plate 6, and the gap is not greater than the thickness of the bottle. When the bottle opening faces the conveying direction, since the distance between two adjacent partition plates 6 cannot accommodate the height of a bottle, one end of the bottle will be located on the partition plate 6, and the bottle will be blocked when passing through the baffle plate 7, and the bottle will be pushed backward from the partition plate 6. It is ensured that there are only bottles horizontally laid on the conveying belt on the feeding belt conveyor 2. A torsion spring is provided on the rotating shaft of the baffle plate 7, so that one end of the top of the baffle plate 7 has a certain swing space to prevent the bottle from getting stuck when it hits the baffle plate 7.

[0041] After the bottle is pushed out from the feeding belt conveyor 2, it enters the vertical section 10 through the inclined section 9. The vertical section 10 is a rectangular cylindrical structure, and its length, width and height are all adapted to the bottle. The bottle can remain stable when it falls on the first belt conveyor 20. The bottle blocking cylinder 11 is extended by default to prevent the bottle from tipping toward the bottle outlet after falling. A photoelectric switch is provided in the vertical section 10. When the bottle is detected, the piston rod of the bottle blocking cylinder 11 is controlled to retract.

[0042] A group of elastic buffers 12 are provided in the top opening of the vertical section 10. The elastic buffers 12 may be metal springs or plastic brushes. The elastic buffers 12 are used to block the incoming bottles. When bottles from the rear enter and squeeze the bottles in front, and the squeezing force is greater than the blocking force of the elastic buffers 12, the bottles in the front fall from the elastic buffers 12 into the vertical section 10, so that the bottles can fall onto the first belt conveyor 20 at a certain interval time.

[0043] The elastic buffer 12 can slow down the speed at which the material bottle falls from the material receiving guide chute 4 .

[0044] The working mode of the filling device 200 is as follows: when the material bottle is transported to the position of the filling machine 21, the first belt conveyor 20 stops, the bottle mouth clamping cylinder 24 starts to clamp the bottle mouth through the clamping claws to keep the position of the material bottle fixed, and the filling head lifting cylinder 26 starts to drive the filling head 25 to extend downward into the material bottle, and the valve of the filling head 25 is opened for filling. After the filling is completed, the filling head lifting cylinder 26 is reset, and the filling head 25 is moved out of the bottle mouth, and then the bottle mouth clamping cylinder 24 is reset to release the bottle mouth, and the first belt conveyor 20 is started, and the filled material bottle is moved to the next station. A photoelectric switch is provided on one side of the first belt conveyor 20 at the filling machine 21 position. The height of the photoelectric switch is the same as the height of the bottle mouth, which is used to detect the position of the bottle mouth of the material bottle, and the filling machine 21 is started according to the signal of the photoelectric switch.

[0045] In the present case, the receiving plate 28 is linked with one of the clamping claws of the bottle mouth clamping cylinder 24, and the receiving plate 28 moves in the opposite direction to the clamping claw, that is, when the bottle mouth clamping cylinder 24 clamps the bottle mouth, the receiving plate 28 swings to one side of the bottle mouth, so that the filling head 25 can move downward and extend into the bottle mouth. After the filling is completed, the filling head 25 moves out, and when the bottle mouth clamping cylinder 24 opens, the receiving plate 28 swings to the top of the bottle mouth, that is, directly below the filling head 25, to prevent liquid from dripping onto the bottle body or the conveyor.

[0046] A T-shaped mounting groove is provided on the top of the receiving plate 28 and runs through the front and back. The adsorption sponge layer is located in the groove, and the adsorption sponge layer can be quickly replaced according to actual needs.

[0047] The filling lifting seat 23 is used to adjust the height of the filling assembly to adapt to the height of the bottle. The adjustable protective plate 50 prevents the bottle from tipping over during the conveying process, and the spacing between the two protective plates 50 can be adjusted according to the model of the bottle.

[0048] The V-shaped bottle mouth positioning plate 27 is provided with an adjustment slot for adjusting the distance between the two V-shaped bottle mouth positioning plates 27 according to the type of the bottle.
