[0018] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0019] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figures 1 to 3As shown, a size detection and conveying device includes a belt conveyor 11, an origin sensor 12, a frame 13, a horizontal guide rail 14, a motor 15, a laser distance sensor 16, a synchronous belt 17, a barrier bar sensor 21, a barrier bar 22, a motor 23, a vertical guide rail 24 and a synchronous belt 25;

[0022] The belt conveyor 11 is placed horizontally and is used for drug transmission. An origin sensor 12 is provided on one side of the end of the belt conveyor 11 for detecting drugs and recording the starting position of the drugs on the belt. A frame 13 is installed on the upper part of the belt conveyor 11, and a horizontal guide rail 14 is installed on the frame 13. A laser distance sensor 16 is installed on the slider located on the horizontal guide rail 14. A motor 15 and a synchronous belt 17 are installed on the frame 13. The motor 15 drives the laser distance sensor 16 through the synchronous belt 17 to scan the medicine box in the horizontal direction along the horizontal guide rail 14 to detect the width and height of the medicine box.

[0023] A baffle sensor 21 is installed on the frame 13 for detecting the origin position of the baffle 22. A motor 23, a vertical guide rail 24 and a synchronous belt 25 are installed on the inner side of the frame 13. The baffle 22 is placed horizontally above the belt and is used to block and align the medicine box when applying medicine. The baffle 22 is installed on a slider of the vertical guide rail 24. The motor 23 drives the baffle 22 to move up and down along the vertical guide rail 24 through the synchronous belt 25, thereby realizing the function of drug feeding access control.

[0024] In specific use, when preparing to feed medicine, the medicine boxes are arranged side by side at the front end of the belt conveyor 11, the left end of the medicine box abuts against the origin sensor 12, and the front end of the medicine box abuts against the blocking rod 22. At this time, the origin sensor 12 records the initial position of the medicine box.

[0025] Medicine box width and height detection: After the medicine boxes are placed, the laser distance sensor 16 scans from the origin sensor 12 from left to right, and determines the starting position of the medicine box width, the medicine box seam position, and the medicine box width end position by identifying the height value change, thereby calculating the width and height of each medicine box in a row, and comparing them with the background standard medicine box size to determine whether any wrong medicines are placed in.

[0026] During the medicine feeding process, the laser distance sensor 16 returns to the position of the left origin sensor 12 after correct detection, the blocking rod 22 is lifted upward, and the medicine box begins to be transported along the belt conveyor 11. When the medicine box leaves the origin sensor 12, the movement time of the medicine box is recorded, and the length value of the medicine box is calculated by the movement time and the linear speed of the belt conveyor 11, and a judgment is made.

[0027] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
