Description

DRIVING METHOD OF CAPSULE INSPECTION DEVICE

The present invention relates to a method for driving a capsule inspection device, and more particularly, to a method for driving a capsule inspection device capable of detecting an abnormality on the surface of a capsule of a pill made of gelatin.

Pills are manufactured through a process of accommodating purified drug powder or granules in a capsule made of gelatin, a transport process, and a packaging process.

In this case, as for the pill, the capsule is made of gelatin, and during the receiving process for accommodating powder or granules, the transporting process and the packing process of the capsule, the capsule is scratched, there is a foreign substance on the surface of the capsule, or is torn when the capsule is combined. This occurs, or the capsule is molded in an irregular shape due to a heat or cooling process, and there is a problem in that a defective capsule is generated.

Accordingly, in the capsule inspection method of Republic of Korea Patent Publication No. 10-2016-0045451 (published on April 27, 2016), a plurality of orthographic surfaces each having a predetermined area photographed while rotating along the circumference of the capsule from the front, and both edges of the capsule Stores in advance the quality data for one or more side perspective surfaces that have been photographed, and one side of the capsule is vacuum-sucked at one rotational position of the rotating plate for vacuum-sucking one side of the capsule and the reverse rotating plate for vacuum-sucking the other side of the capsule. Two or more cameras are arranged along the circumference of one side to photograph each orthographic plane expressed as a plane when the capsule is projected from the front at different angles, and the side perspective plane exposed when the tablet is adsorbed by the rotating plate and the inverted rotating plate, respectively Disclosed is a capsule inspection method in which one or more cameras are placed and photographed, and a pre-stored good product data is compared with the data of the front and side views to select defective products.

However, such a conventional capsule inspection method determines whether the capsule is defective through a plurality of cameras arranged at various angles in a state in which the capsule is vacuum-adsorbed on the rotating plate and the reverse rotating plate. In this case, the capsule inspection method is to vacuum the capsule Since it rotates in a state of being adsorbed, if the position of the capsule is not specified and the capsule is arranged in a slightly distorted state, the inspection defect is continuously generated.

In addition, the conventional capsule inspection method requires a plurality of cameras to be photographed from various angles to inspect the entire surface of the capsule. Due to this very high level of advancement, the price of the product rises, and even if the advanced vision inspection device is used, if the vacuum adsorption position of the capsule and the rotating plate deviate even a little, a bad signal about the capsule will be generated regardless of whether the capsule is actually defective. There is a problem with continuous transmission.

Furthermore, in the conventional capsule inspection method, when a defective capsule occurs, the defective capsule must be separated separately. There is a problem in that the received capsule must be separated.

In addition, in the conventional capsule inspection method, a plurality of cameras are diagonally arranged to photograph the convex end of the capsule when the capsule adsorbed on the rotating plate is rotated. In addition to increasing the cost, it causes a problem that a bad signal is continuously transmitted when the vacuum adsorption position is even slightly deviated.

The rail support 64 is composed of a plurality, each of which is spaced apart from each other to support the lower portion of the binding plate rail 63, thereby fixing the binding plate rail 63.

The linear motor 65 is coupled between the capsule binding plate 61 and the rail support 64 to transfer the capsule binding plate 61 in the longitudinal direction of the binding plate rail 63 . In this case, the drive shaft 65a of the linear motor 65 is ball-screw coupled to the drive shaft coupling body 65b formed on the capsule binding plate 61 when it is coupled to the capsule binding plate 61, so that the ball screw type linear motor can be composed of However, in the present invention, the type of the linear motor 65 is not limited to the ball screw method, and it is of course that a linear induction motor may be modified and implemented.

The driving control unit 70 interlocks with the roller rotating unit 20 , the image processing unit 40 , the linear motor 65 of the suction conveying unit 60 , and the suction unit 62 of the suction conveying unit 60 . Such a drive control unit 70 sequentially controls the linear motor 65 of the suction transfer unit 60 and the suction unit 62 of the suction transfer unit 60 according to a preset program, specifically, the drive control unit 70 controls the linear motor 65 of the adsorption transfer unit 60 to determine the position of the capsule binding plate 61 in the upper space of the unexamined capsule transfer unit 80, the upper space of the roller unit 10, and the normal capsule The upper space of the discharging unit 100 and the upper space of the defective capsule discharging unit 110 are arranged to be located, respectively, and the suction unit 62 controls the driving in each space to adsorb the capsule 1a or the capsule ( 1a) is discharged. In this case, the driving control unit 70 may control the position by receiving a position input from a position sensor (not shown) installed in each of the binding plate rail 63 sections when controlling the position of the capsule binding plate 61, and this Since it is a technique generally used to control the position of the same position sensor in the art, a detailed description thereof will be omitted.

The normal capsule discharging part 100 is seated on the base part 90 and is spaced apart from the roller rotating part 20 . In this case, the normal capsule discharge part 100 is formed in a plate shape with both sides folded, and is inclined from the base part 90 , and the first pedestal is coupled and supported between the base part 90 and the base part 90 . Here, when the capsule 1a, which has been determined as normal by the image processing unit 40, is transferred to the upper space of the normal capsule discharging unit 100 in a state in which it is adsorbed by the adsorption transfer unit 60, the adsorption is released. In, by allowing the falling capsule (1a) to slide in one direction, it serves to collect the normal capsule (1a) in a specific area.
