Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical manufacturing, in particular to a tablet detection and sorting device. Background Art

[0002] Existing tablet inspection and sorting are mostly manual operations. Tablets are laid flat on a conveyor belt and transported. Manual workers conduct batch visual inspections under a bright light and sort out defective products with appearance defects. For example, the engraving effect of laser-engraved tablets is inspected. Although batch inspection can be achieved, the workload of the workers is too heavy, and the tablets are laid flat in a messy state on the conveyor belt. It is difficult to avoid missed inspections due to fatigue, which may cause defective products to be mixed with qualified products.

[0003] Therefore, those skilled in the art are committed to developing a tablet detection and sorting device that can fully automatically detect and sort tablets with high accuracy. Summary of the Invention

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a tablet detection and sorting device that can fully automatically detect and sort tablets with high accuracy.

[0005] To achieve the above-mentioned objectives, the utility model provides a tablet inspection and sorting device, comprising a feeding mechanism for providing tablets, a separating mechanism for discharging tablets one by one, a conveying mechanism for conveying tablets in a matrix manner, a processing head for processing the tablets, a camera for visually inspecting the tablets, a defective box for collecting tablets with unqualified appearances, a feeding mechanism for replenishing qualified tablets, and a negative pressure discharge belt for matrix-type discharge.

[0006] The feeding mechanism includes a vibrating hopper, and a plurality of discharge pipes are obliquely arranged below the vibrating hopper; the separation mechanism includes a plurality of separation pipes arranged obliquely corresponding to the discharge pipes, a cylinder is provided on one side of the end of the separation pipe, and an upper plate and a lower plate are fixed on the telescopic rod of the cylinder respectively, the upper plate is extended downwardly to be provided with an upper separation rod which can be inserted into the separation pipe, and the lower plate is extended upward to be provided with a lower separation rod which can be inserted into the separation pipe, the upper separation rod and the lower separation rod are arranged in sequence along the conveying direction of the separation pipe and the spacing matches the diameter of a single tablet, the upper separation rod and the lower separation rod are alternately inserted into the separation pipe when the telescopic rod reciprocates, and the cross-sectional shape of the discharge pipe and the separation pipe matches the shape of the tablets so that the tablets are conveyed in a single row in the pipe;

[0007] The conveying mechanism includes a negative pressure conveying belt, on which a plurality of rows of first suction ports corresponding one to one with the separation tubes are provided; a processing head and a camera are sequentially provided above the negative pressure conveying belt, the defective product box is provided at the end of the negative pressure conveying belt, and a vacuum breaking element is provided inside the negative pressure conveying belt at a position corresponding to the defective product box;

[0008] The feeding mechanism includes a negative pressure feeding belt and a single row of second suction ports arranged on the negative pressure feeding belt. The negative pressure feeding belt is located below the negative pressure conveying belt and the conveying directions of the two are perpendicular.

[0009] Furthermore, the structure of the negative pressure discharging belt is the same as that of the negative pressure conveying belt, and the negative pressure discharging belt is arranged parallel to and below the negative pressure conveying belt.

[0010] Furthermore, the conveying direction of the negative pressure discharging belt structure is opposite to that of the negative pressure conveying belt.

[0011] Furthermore, each separator tube has two upper separator rods and two lower separator rods, and the two upper separator rods and the two lower separator rods are symmetrically arranged with respect to the centerline of the separator tube. Based on this, when the upper separator rod or the lower separator rod is inserted into the separator tube, the two-rod arrangement allows it to be inserted into the gap on both sides of the tangent point between the two tablets, thus preventing the separator rods from hitting the tablets during insertion and producing defective products.

[0012] Furthermore, the ends of the upper separation rod and the lower separation rod are tapered.

[0014] Furthermore, the processing head is a laser engraving head.

[0015] Furthermore, the suction force of the first suction port is greater than that of the second suction port. Therefore, when feeding, it is unnecessary to break the vacuum of the corresponding second suction port of the negative pressure feeding belt, and the first suction port can directly suck the qualified tablets on the second suction port to feed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The device requires no manual operation and can fully automatically detect and sort tablets with high efficiency and accuracy, greatly reducing the possibility of defective products being mixed into qualified products.

[0030] The feeding mechanism 1 includes a vibrating hopper 11, and a plurality of discharge pipes 12 are obliquely arranged below the vibrating hopper 11; the separation mechanism 2 includes a plurality of separation pipes 21 obliquely arranged corresponding to the discharge pipes 12, and a cylinder 22 is provided on one side of the end of the separation pipe 21. An upper plate 24 and a lower plate 26 are fixed on the telescopic rod 23 of the cylinder 22 respectively. The upper plate 24 extends downward and is provided with an upper separation rod 25 that can be inserted into the separation pipe 21, and the lower plate 26 extends upward and is provided with a lower separation rod 27 that can be inserted into the separation pipe 21. The upper separation rod 25 and the lower separation rod 27 are arranged in sequence along the conveying direction of the separation pipe 21 and the spacing matches the diameter of a single tablet. The upper separation rod 25 and the lower separation rod 27 are alternately inserted into the separation pipe 21 when the telescopic rod 23 reciprocates. The cross-sectional shapes of the discharge pipe 12 and the separation pipe 21 match the shape of the tablets so that the tablets 9 are conveyed in a single row in the pipe;

[0031] The conveying mechanism 3 includes a negative pressure conveying belt 31, on which are provided a plurality of rows of first suction ports 32 corresponding one to one with the separation tubes 21; a processing head 4 and a camera 5 are sequentially provided above the negative pressure conveying belt 31, and the defective product box 6 is provided at the end of the negative pressure conveying belt 31, and a vacuum breaking element is provided inside the negative pressure conveying belt 31 at a position corresponding to the defective product box 6;

[0032] The feeding mechanism 7 includes a negative pressure feeding belt 71 and a single row of second suction ports 72 arranged on the negative pressure feeding belt 71. The negative pressure feeding belt 71 is located below the negative pressure conveying belt 31 and the conveying directions of the two are perpendicular.

[0033] Furthermore, the structure of the negative pressure discharge belt 8 is the same as that of the negative pressure conveying belt 31 , and the negative pressure discharge belt 8 is arranged parallel to and below the negative pressure conveying belt 31 .

[0034] Furthermore, the conveying direction of the negative pressure discharge belt 8 structure is opposite to that of the negative pressure conveying belt 31.

[0035] Furthermore, each separator tube 21 has two upper separator rods 25 and two lower separator rods 27, and the two upper separator rods 25 and the two lower separator rods 27 are symmetrically arranged relative to the center line of the separator tube 21. Based on this, when the upper separator rod 25 or the lower separator rod 27 is inserted into the separator tube 21, the two-rod arrangement allows it to be inserted into the gap on both sides of the tangent point between the two tablets, preventing the separator rods from hitting the tablets during insertion and producing defective products.

[0036] Furthermore, the ends of the upper separation rod 25 and the lower separation rod 27 are tapered.

[0038] Furthermore, the processing head is a laser engraving head.

[0039] Furthermore, the adsorption force of the first suction port 32 is greater than that of the second suction port 72. Therefore, when feeding, it is unnecessary to break the vacuum of the corresponding second suction port 72 of the negative pressure feeding belt 71, and the first suction port 32 can directly suck the qualified tablets on the second suction port 72 to feed.

[0040] The working principle of this utility model:

[0041] The vibrating hopper 11 is connected to the discharge port of the granulator, and under the action of vibration, the tablets are transported in a single row to the discharge pipe 12 and the separation pipe 2 in sequence; when the cylinder 22 is extended, the upper separation rod 25 is inserted into the separation pipe 21 and blocks the first tablet downstream; when the cylinder 22 is contracted, the lower separation rod 27 is inserted into the separation pipe 21 and blocks the second tablet downstream, and the upper separation rod 25 will withdraw from the separation pipe 21 and release the first tablet, so that the tablets are transported one by one from the separation pipe 2 to the negative pressure conveyor belt 31, and the conveying speed is controlled by combining the conveying step and suction port spacing of the negative pressure conveyor belt 31, so that the landing point of the tablets on the negative pressure conveyor belt 31 is located at the first suction port 32 and is positioned by negative pressure adsorption; the negative pressure adsorption conveyor belt is a conventional existing technology in this field, and its specific details are not repeated here. The negative pressure conveyor belt 31 transports the tablets downstream, passing through the processing head 4 and the camera 5. Processing such as laser engraving is performed at the processing head 4, and the tablets are inspected for appearance defects at the camera 5. When passing through the defective product bin 6, the defective products are desorbed by the corresponding vacuum breaking element and fall into the defective product bin 6. Acceptable products continue to travel along the negative pressure conveyor belt 31 to its lower surface. The negative pressure refilling belt 71 refills the vacant first suction port 32 after the defective products are removed. The qualified products are then neatly and neatly presented in a matrix to the negative pressure discharge belt 8 for discharge, facilitating subsequent packaging and other operations.

[0042] The above describes in detail the preferred embodiments of the present invention. It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by a person skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology shall be within the scope of protection defined by the claims.
