It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0022] like Figures 1 to 5As shown, a preferred embodiment of the bottle conveying mechanism of the present invention includes a frame 11, a first limiting plate 21, a second limiting plate 22, a detection device 3, a bottle blowing device 4 and a controller; a conveyor belt 12 for conveying bottles 100 is provided on the frame 11; the first limiting plate 21 and the second limiting plate 22 are arranged at opposite sides of the conveying direction of the conveyor belt 12 with relative spacing, and the interval between the second limiting plate 22 and the first limiting plate 21 forms a limiting channel 23 for the bottle 100 to pass through; the length direction of the limiting channel 23 is parallel to the length direction of the conveyor belt 12, and the lower end of the first limiting plate 21 is provided with a bottle outlet 211 connecting the limiting channel 23 with the outside world; the detection device 3 is connected to the first limiting plate 21 or the second limiting plate 22 or the frame 11. In this embodiment, the first limiting plate 21 is respectively connected to both sides of the frame 11 through the L-shaped connecting piece 6; the detection device 3 is used to detect whether the bottle body 100 moved to the front of the bottle outlet 211 is tilted; the bottle blowing device 4 is arranged on the second limiting plate 22 and is opposite to the bottle outlet 211; the detection device 3 and the bottle blowing device 4 are both electrically connected to the controller, and the detection device 3 detects that the bottle body 100 is tilted, and the controller controls the bottle blowing device 4 to blow air, which can blow the tilted bottle body 100 from the bottle outlet 211 to the outside of the limiting channel 23, thereby realizing the removal of the tilted bottle body 100, thereby preventing the tilted bottle body 100 from entering the next work station and avoiding defects such as bottle jamming at the next work station.

[0023] The detection device 3 includes a first sensor 31 and a second sensor 32. The first sensor 31 is arranged on the first limiting plate 21 or the second limiting plate 22, and the second sensor 32 is arranged on the first limiting plate 21 or the second limiting plate 22. The first sensor 31 and the second sensor 32 are spaced apart from each other. The first sensor 31 and the second sensor 32 are both non-contact object measuring sensors. The measuring end of the first sensor 31 is opposite to the upper part of the upright bottle body 100 and is arranged vertically offset from the tilted bottle body 100. The measuring end of the second sensor 32 is arranged opposite to the tilted bottle body 100. The first sensor 31 and the second sensor 32 are both electrically connected to the controller. In this embodiment, the first sensor 31 and the second sensor 32 are both infrared sensors. The first limiting plate 21 is provided with two through holes spaced apart from each other. Both through holes are arranged along the width direction of the conveyor belt 12. The first sensor 31 is arranged in the higher through hole, and the second sensor 32 is arranged in the lower through hole. In this embodiment, the bottle 100 is a flat, oval bottle. The width of the limiting channel 23 matches the thickness of the bottle 100, allowing the bottle 100 to move smoothly within the limiting channel 23 and prevent the bottle 100 from lying flat on the conveyor belt 12. Some bottles 100 may fall sideways on the conveyor belt 12. The top of the bottle outlet 211 is lower than the top of an upright bottle 100 and higher than the top of a fallen bottle 100. This allows a bottle 100 that has fallen over to pass through the bottle outlet 211 smoothly, while an upright bottle 100 will smoothly follow the conveyor belt 12 under the constraint of the first limiting plate 21 located at the upper end of the bottle outlet 211. In other embodiments of the present invention, the detection device 3 may employ an image recognition device to detect whether the bottle 100 has fallen over.

[0024] In this embodiment, the bottle blowing device 4 includes an air nozzle 41 connected to the second limiting plate 22, an air supply pipe 42 for supplying air to the air nozzle 41, and a control valve 43 provided on the air supply pipe 42. The control valve 43 is electrically connected to the controller. Among them, the air supply pipe 42 can be directly connected to the compressed air supply system of the workshop. When the first sensor 31 does not detect the bottle body 100 and the second sensor 32 detects the bottle body 100, it means that the bottle body 100 located in front of the bottle outlet 211 has fallen over, and the controller opens the control valve 43. When the conveyor belt 12 transports the fallen bottle body 100 to the bottle outlet 211, the air nozzle 41 blows the fallen bottle body 100 out of the bottle outlet 211. The duration of the opening of the control valve 43 can be adjusted by a timer. The duration of the opening of the control valve 43 is set according to the feeding speed of the conveyor belt 12 and the interval between two adjacent bottles 100 to ensure that the air nozzle 41 can smoothly blow away the fallen bottle body 100 while avoiding the air nozzle 41 blowing air to the upright bottle body 100. In this embodiment, the control valve 43 is a solenoid valve.

[0025] In this embodiment, the air nozzle 41 has a rectangular air outlet. The rectangular air outlet is spaced apart from the bottle outlet 211 along the width direction of the conveyor belt 12, and the length of the rectangular air outlet is arranged along the conveying direction. The rectangular air outlet ensures that the compressed air ejected by the air nozzle 41 can act on the tilted bottle 100 for a longer time, which facilitates the air nozzle 41 to successfully blow away the tilted bottle 100. Specifically, a mounting hole 221 is formed at a position opposite the bottle outlet 211 along the width direction of the conveyor belt 12, and the air nozzle 41 is inserted into the mounting hole 221.

[0026] To facilitate the collection of fallen bottles 100, in this embodiment, the bottle conveying mechanism further includes a bottle collecting box 5 connected to the first limiting plate 21 or the frame 11. The bottle blowing device 4, the bottle outlet 211, and the bottle collecting box 5 are sequentially spaced along the width of the conveyor belt 12. The opening of the bottle collecting box 5 is slightly lower than the conveyor belt 12, and the air nozzle 41 blows the fallen bottles 100 out of the bottle outlet 211 and into the bottle collecting box 5.

[0027] Furthermore, to prevent the bottle collecting box 5 from flying out of the collecting box 5 due to excessive jet pressure from the air nozzle 41, in this embodiment, the wall of the collecting box 5 on the side away from the conveyor belt 12 is higher than the wall of the collecting box 5 on the side close to the conveyor belt 12, along the width direction of the conveyor belt 12. Specifically, the opening of the collecting box 5 has a chamfered structure arranged in an up-and-down manner, with the lower side of the opening close to the conveyor belt 12 and the higher end of the opening away from the conveyor belt 12. In this embodiment, the wall of the collecting box 5 on the side away from the conveyor belt 12 is defined as a first wall 51, and the wall of the collecting box 5 on the side close to the conveyor belt 12 is defined as a second wall 52. The first wall 51 is higher than the second wall 52.

[0028] An embodiment of a medicine packaging line includes the above-mentioned bottle conveying mechanism.

[0029] In summary, the bottle conveying mechanism of the present invention includes a frame 11, a first limiting plate 21, a second limiting plate 22, a detection device 3, a bottle blowing device 4 and a controller. The frame 11 is provided with a conveyor belt 12 for conveying bottles 100; the first limiting plate 21 and the second limiting plate 22 are arranged on both sides of the conveying direction of the conveyor belt 12 with relative spacing, and the gap between the second limiting plate 22 and the first limiting plate 21 forms a limiting channel 23 for the bottles 100 to pass through; the lower end of the first limiting plate 21 is provided with a bottle outlet 211 connecting the limiting channel 23 with the outside world; The detection device 3 is used to detect whether the bottle body 100 moved to the front of the bottle outlet 211 is tilted; the bottle blowing device 4 is arranged on the second limiting plate 22 and opposite to the bottle outlet 211; the detection device 3 and the bottle blowing device 4 are both electrically connected to the controller. When the detection device 3 detects that the bottle body 100 is tilted, the controller controls the bottle blowing device 4 to blow air, which can blow the tilted bottle body 100 from the bottle outlet 211 to the outside of the limiting channel 23, thereby realizing the removal of the tilted bottle body 100, thereby preventing the tilted bottle body 100 from entering the next work station, and avoiding defects such as bottle jamming at the next work station.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
