[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0027] like Figure 1-6 As shown, the present invention proposes a novel medicine bottle printing device, comprising a conveying mechanism and a printing mechanism 4 mounted on a frame 1. The conveying mechanism includes a loading mechanism and a horizontally arranged first conveyor 5 and a second conveyor 7. The printing mechanism 4 is located above the first conveyor 5. The first conveyor 5 is a chain conveyor, and the medicine bottles are supported horizontally between two adjacent chain rods above the chain conveyor. The printing mechanism 4 can print on the medicine bottles on the chain conveyor.

[0028] The feed end of the first conveyor 5 is connected to the discharge end of the loading mechanism. The loading mechanism comprises a loading conveyor belt 2 and a first feed screw 31 and a second feed screw 33 mounted on a first housing 30. Medicine bottles are placed upright on the loading conveyor belt 2 and transported forward to the first feed screw 31. The first feed screw 31 is mounted horizontally at the discharge end of the loading conveyor belt 2, perpendicular to the feeding direction of the loading conveyor belt 2. The second feed screw 33 is arranged side by side with the first feed screw 31, with the end facing the end. A vertical baffle 301 is installed on one side of the discharge end of the first feed screw 31. The discharge end of the second feed screw 33 is connected to the feed end of the first conveyor 5. Under the conveying of the first feeding screw 31, the medicine bottle enters the feeding gap between the vertical baffle 301 and the first feeding screw 31 in a vertical state, and is fed into the feeding end of the second feeding screw 33 from the feeding gap between the vertical baffle 301 and the first feeding screw 31. The second feeding screw 33 is provided with a first curved baffle 32 on the side away from the vertical baffle 301, and the first curved baffle 32 is provided with an arc surface that gradually turns from vertical to horizontal near the second feeding screw 33, so that the medicine bottle can be gradually transformed from a vertical state to a horizontal lying state, which is more convenient for the horizontal and stable conveying of the medicine bottle on the first conveyor 5.

[0029] The first conveyor 5 is higher than the second conveyor 7, and the discharge end of the first conveyor 5 is connected to the feed end of the second conveyor 7 through a conveying and transferring mechanism 6. Among them, the second conveyor 7 also adopts a chain conveyor. Specifically, the conveying and transferring mechanism 6 includes a first guide plate 62 and a first disc 61. A plurality of arc-shaped first grooves 611 are provided on the circumferential surface of the first disc 61 at equal intervals. A first negative pressure suction hole 612 connected to an external negative pressure air source is provided in the first groove 611. Under the negative pressure suction action of the first negative pressure suction hole 612, the medicine bottles from the first conveyor 5 can be effectively adsorbed and grasped, making the transfer of the medicine bottles from the first conveyor 5 to the second conveyor 7 with a height difference more stable. The powered first disc 61 is vertically rotatably installed at the tail of the first conveyor 5 and is arranged above the feed end of the second conveyor 7. The rotation of the first disc 61 is coordinated with the feeding speed of the first conveyor 5, the second conveyor 7, the first feeding screw 31 and the second feeding screw 33 and other transmission devices, thereby achieving stable transmission of the medicine bottles.

[0030] The first guide plate 62 is mounted below the tail end of the first conveyor 5. It is provided with a first guide arc surface that mates with the first faceplate 61. The feeding gap between the first faceplate 61 and the first guide plate 62 receives the discharge end of the first conveyor 5 above, and is connected to the feed end of the second conveyor 7 below. After printing, the medicine bottles on the conveyor enter the feeding gap between the first faceplate 61 and the first guide plate 62. The medicine bottles stuck in the first groove 611 of the first faceplate 61 are attracted by negative pressure and, guided by the first guide plate 62, land smoothly on the second conveyor 7, completing the smooth transfer of the medicine bottles between the first conveyor 5 and the second conveyor 7, which have a height difference.

[0031] Above the second conveyor 7, a bottle inspection mechanism 83 for checking the printed labels on the bottles and a waste ejection mechanism 84 for rejecting waste printed bottles are installed. These two mechanisms are positioned sequentially above the second conveyor 7 along its feed direction. The bottle inspection mechanism 83 utilizes an existing visual inspection device. The waste ejection mechanism 84 can utilize existing mechanical grippers, negative pressure nozzles, or other similar mechanisms.

[0032] In addition, a height detection mechanism 82 for detecting the height of the medicine bottles is installed on the second conveyor 7 in front of the medicine bottle detection mechanism 83 , and a bottle unscrambling mechanism 81 is also provided on the second conveyor 7 in front of the height detection mechanism 82 .

[0033] Specifically, the height detection mechanism 82 includes a detection frame 821, a slide rail 822, a top block 824, a detector and a tension spring 825. The detection frame 821 is installed on the frame 1, and the slide rail 822 is horizontally installed on the detection frame 821. A movable frame 823 is provided on the slide rail 822 for horizontal sliding. The movable frame 823 includes a first movable plate 8231, a second movable plate 8232 and a third movable plate 8233. The first movable plate 8231 is an L-shaped structure. The vertical portion of the first movable plate 8231 is horizontally slidably installed. Mounted on the slide rail 822, the second movable plate 8232 is adjustable forward and backward on the horizontal portion of the first movable plate 8231, and the third movable plate 8233 is adjustable up and down on the second movable plate 8232. The top block 824 is fixedly connected to the bottom of the third movable plate 8233. The bottom surface of the top block 824 is provided with an inclined surface that cooperates with the medicine bottles on the second conveyor 7. The ends of the tension spring 825 are respectively fixedly connected horizontally to the movable frame 823 and the detection frame 821, which is used to reset the movable frame 823 and the top block 824. The detector includes a photoelectric detection component 827 and a baffle 826. One end of the baffle 826 is fixedly connected to the first movable plate 8231, and the other end cooperates with the photoelectric detection component 827 mounted on the detection frame 821. When the medicine bottle is normally conveyed on the second conveyor 7, it is between two adjacent chain rods and its height is lower than the top block 824 above the second conveyor 7, and it can pass under the height detection mechanism 82; when problems such as bottle jumping occur, the height of the problem medicine bottle will be higher than the bottom of the top block 824. As the second conveyor 7 is conveyed forward, the problem medicine bottle will pass through the inclined surface below the top block 824 and move horizontally against the top block 824, thereby driving the movable frame 823 to move, so that the blocking piece 826 on the movable frame 823 disengages from the photoelectric detection component 827, and then detects that the height of this medicine bottle is abnormal, and the equipment is shut down in time to ensure that the medicine bottle can pass stably through the first kick-off mechanism and operate effectively, thereby effectively avoiding the occurrence of medicine bottle breakage accidents.

[0034] The bottle sorting mechanism 81 includes a bottle sorting positioning plate 811 horizontally arranged above the second conveyor 7 near the bottom side of the medicine bottle, which is used to position and organize the medicine bottles conveyed on the second conveyor 7. The bottle sorting positioning plate 811 is adjustably mounted on the frame 1 front and back through the corresponding adjustment plate 812, and the tail of the bottle sorting positioning plate 811 is tilted toward the middle of the second conveyor 7 at a certain angle along the feeding direction of the second conveyor 7. Under the guiding action of the inclined bottle sorting positioning plate 811, the medicine bottles on the second conveyor 7 can be effectively sorted and positioned to make them more orderly, thereby making the subsequent bottle printing detection more accurate and making it easier for the subsequent medicine bottles to be effectively placed in trays and boxed.

[0035] Both the transport mechanism 6 and the waste removal mechanism 84 are vertically adjustable and mounted on the frame 1. In practice, the transport mechanism 6 and the waste removal mechanism 84 are mounted on corresponding mobile modules on the frame 1. These modules slide vertically on the frame 1. Furthermore, motorized lead screws corresponding to the respective mobile modules are vertically mounted on the frame 1. The mobile modules are threadedly mounted on the corresponding motorized lead screws. Controlling the rotation of the corresponding motorized lead screws drives the transport mechanism 6 or the waste removal mechanism 84 upward and downward, through the corresponding mobile module. This makes the device easier to install and debug, and adapts to the processing of different types of medicine bottles.

[0036] When using the present invention, the feeding conveyor belt 2 will feed in medicine bottles in an upright state, and the first feeding screw 31, the second feeding screw 33 and the first arc-shaped baffle 32 will cooperate to transmit the medicine bottles from an upright state to a horizontal state and send them to the first conveyor 5. After the bottle body is printed by the printing mechanism 4, the medicine bottles are smoothly transported to the second conveyor 7 with a height difference through the transmission and transfer mechanism 6; the medicine bottles transported on the second conveyor 7 will pass through the medicine bottle detection mechanism 83 to detect the printing on the medicine bottles. The medicine bottles with unqualified printing will be transported and grabbed by the kicking mechanism 84, thereby realizing efficient and stable transmission and printing operations of the medicine bottles.

[0037] Obviously, the embodiments described above are only some of the embodiments of the present application, rather than all of the embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms.
