[0002] A kind of oral liquid or carbenicillin bottle (hereinafter collectively referred to as bottle) packaging material 9, as shown in Figure Figure 1 The packaging material 9 includes a box holder 91, and the bottle 92 with the bottle mouth downward is placed upside down on the box holder 91, and the box holder 91 is wrapped with a plastic film. For this type of packaging material, the existing unpacking machine generally uses ring cutting to cut the film during unpacking. Before cutting the film, a turnover mechanism is needed to turn it over so that the bottle mouth is upward, and the box holder 91 is inverted on the bottle 92. Then the film cutting robot is used to cut the film. When cutting the film, the bottle 92 needs to be protected, so the film is usually cut on the surface of the box holder 91. However, due to the low height of the box holder 91, i.e. the high cutting position, a large stress is applied, which often causes the box holder 91 to be tilted, resulting in film cutting failure. In severe cases, the bottle 92 may fall off and scatter, affecting the overall work efficiency. SUMMARY

[0024] Example one:

[0025] Figures 1 to 4 An embodiment of the packaging material unpacking machine with a box support of the application is shown, which includes a rack 1 and a conveying channel 2 arranged on the rack 1. The rack 1 is provided with a turnover device 3, a film cutting station 5, a box taking device 6, and a bottle discharging device 7 arranged in sequence along the conveying direction of the conveying channel 2. The film cutting station 5 is provided with a pressing support device 8 for preventing the box support from being lifted on one side of the conveying channel 2 and a film cutting manipulator 4 with a cutter 41. The box support 91 of the packaging material 9 covers the bottle body 92 during film cutting. After the cutter 41 cuts through two adjacent corners, the pressing support device 8 presses the box support 91.

[0026] The overall working process is as follows:

[0027] I. The packaging material 9 is pushed to the turnover device 3 by the front-end packaging material conveying mechanism. The turnover device 3 clamps and turns the packaging material 9, so that the state of the packaging material 9 becomes bottle mouth upward, and the box support 91 is in the upper state, which facilitates the completion of the subsequent box taking action.

[0028] II. The packaging material 9 is conveyed from the turnover device 3 to the film cutting station 5, and the turnover device 3 is returned to the original position to wait for the next packaging material 9 to repeat the clamping and turnover operation;

[0029] III. The film cutting manipulator 4 drives the cutting knife 41 to cut the plastic film around the box holder 91 from the first side of the box holder 91, and after passing the second corner (the intersection of the second side and the third side) of the box holder 91, the pressing device 8 presses the second side top or the second corner top of the box holder 91, and then continues to cut the film until the cutting is completed. Then, the pressing device 8 releases the pressing action on the box holder 91 and returns to the position that does not hinder the movement of the film cutting manipulator 4 to cut the next box holder 91.

[0030] IV. After the film cutting is completed, the packaging material 9 is conveyed to the box taking station, and the box taking device 6 operates to take away the box holder 91 on the bottle body 92. The bottom film remains in the film cutting station 5 and is taken away.

[0031] V. The bottle body 92 is conveyed to the bottle output device 7 for output.

[0032] The packaging material unpacking machine with box holders in the present application cuts the plastic film around the box holder 91 from the first side of the box holder 91, and after passing a corner, the plastic film is pressed by the pressing device 8, and the cutting knife 41 rotates to complete the cutting, ensuring that the box holder 91 above the bottle body 92 does not lift up when the last two corners are cut, avoiding inaccurate film cutting position, excessive residual bottom film, and scattered or inverted bottles.

[0033] Specifically, the box holder 91 is square.

[0034] In the present embodiment, as shown in Figure 3 and Figure 4 , the pressing device 8 includes a mounting seat 81, a telescopic mechanism 82 that can be telescoped to one side of the conveying channel 2, a lifting mechanism 83 that can be lifted, and a pressing plate 84 provided at the bottom end of the lifting mechanism 83. The mounting seat 81 is provided on the rack 1, the telescopic mechanism 82 is provided on the mounting seat 81, and the lifting mechanism 83 is provided on the telescopic mechanism 82. The pressing plate 84 is driven by the lifting mechanism 83 to realize lifting movement, and is driven by the telescopic mechanism 82 to realize telescopic movement to one side of the conveying channel 2. In this way, when the cutting knife 41 cuts the first side, the first corner, the second side, and the second corner of the box holder 91, the telescopic mechanism 82 is telescoped to the outside of the conveying channel 2, avoiding hindering the movement of the film cutting manipulator 4 driving the cutting knife 41, and at the same time, enabling the pressing plate 84 to adapt to packaging materials 9 of different heights. After the film cutting is completed, the pressing plate 84 is lifted by the lifting mechanism 83 to release the pressing action on the box holder 91, and then the pressing plate 84 is retracted to the side of the conveying channel 2 by the telescopic mechanism 82 to prevent hindering the cutting of the next box holder 91 by the film cutting manipulator 4.

[0035] In the embodiment, the horizontal telescopic mechanism 82 comprises a horizontal telescopic driving member 821 and a first mounting plate 822. The horizontal telescopic driving member 821 is arranged on the mounting base 81, and the first mounting plate 822 is arranged at one end of the horizontal telescopic driving member 821 facing the conveying channel 2. The lifting mechanism 83 is arranged on the first mounting plate 822. The horizontal telescopic mechanism 82 can be a horizontal telescopic cylinder, which drives the first mounting plate 822 to perform telescopic movement to one side of the conveying channel 2. The first mounting plate 822 is vertically arranged.

[0036] In the embodiment, the lifting mechanism 83 comprises a vertical telescopic driving member 85 and a second mounting plate 86. The vertical telescopic driving member 85 is arranged on the first mounting plate 822, and the second mounting plate 86 is arranged at the bottom end of the vertical telescopic driving member 85. The pressing plate 84 is arranged on the second mounting plate 86. The vertical telescopic driving member 85 is vertically arranged on the first mounting plate 822 and can be a lifting cylinder, which drives the pressing plate 84 to press the top surface of the plastic film of the box support 91. The second mounting plate 86 is horizontally arranged, and the pressing plate 84 is horizontally fixed on the bottom surface of the second mounting plate 86.

[0037] In the embodiment, the vertical telescopic driving member 85 comprises a cylinder body 851 and a piston rod 852. The cylinder body 851 is arranged on the first mounting plate 822, and the piston rod 852 vertically penetrates the cylinder body 851. The second mounting plate 86 is arranged at the bottom end of the piston rod 852, and the top end of the piston rod 852 is provided with a limiting mechanism 853. The limiting mechanism 853 can limit the maximum height of the box support 91 descending, so as to prevent the box support 91 and the bottle body 92 below the box support 91 from being damaged. Therefore, a flexible pad can also be arranged at the bottom of the pressing plate 84. Specifically, the limiting mechanism 853 comprises a limiting plate 854 and a limiting member 855. The limiting plate 854 is arranged on the piston rod 852, and the limiting member 855 penetrates the limiting plate 854 and is threadedly connected with the limiting plate 854. The limiting member 855 is vertically arranged. When the bottom surface of the limiting member 855 abuts against the top surface of the cylinder body 851, it is the lowest position of the box support 91 descending. By screwing the limiting member 855, the lowest position of the box support 91 descending can be adjusted, which is simple in structure and convenient to adjust.

The structure of the embodiment is basically the same as that of embodiment one, and the difference is that the rack 1 is provided with a top film taking device 11 between the film cutting station 5 and the box taking device 6.

[0040] The overall working process is as follows:

[0041] I. The packaging material 9 is pushed to the turnover device 3 by the front-end packaging material conveying mechanism. The turnover device 3 clamps and turns over the packaging material 9, so that the state of the packaging material 9 becomes that the bottle opening is upward and the box support 91 is above, which facilitates the completion of the subsequent box taking action.

[0042] II. The packaging material 9 is transported from the turnover device 3 to the film cutting station 5, and the turnover device 3 is returned to the original position to wait for the next packaging material 9 to repeat the clamping and turnover operation;

[0043] III. The film cutting manipulator 4 drives the cutting knife 41 to cut the plastic film around the box support 91 from the first side of the box support 91, and after passing the second corner (the intersection of the second side and the third side) of the box support 91, the pressing device 8 presses the second side top or the second corner top of the box support 91, and then continues to cut the film until the cutting is completed; then, the pressing device 8 releases the pressing action on the box support 91 and returns to the position that does not hinder the movement of the film cutting manipulator 4 to cut the next box support 91;

[0044] IV. After the film cutting is completed, the packaging material 9 is transported along the conveying channel 2 to the top film taking station, and the top film taking device 11 clamps the top film on the box support 91 and puts it into the plastic film recycling frame, and then the top film taking device 11 returns to the original position to wait for the next packaging material 9 to take the top film; the bottom film remains in the film cutting station 5 and is taken away;

[0045] V. The packaging material 9 is transported along the conveying channel 2 to the box taking station, and the box taking device 6 takes away the box support 91 on the bottle body 92;

[0046] VI. The bottle body 92 is transported to the bottle output device 7 to output.
