The first screw 310 may be located on the same extension line as the revolving path (W) of the turret assembly 200. Since the first screw 310 is disposed on the same line as the second screw 320, the bottle B transferred by the second screw 320 may be transferred to the idle path W of the turret assembly 200. have.

In this case, a first alignment groove 311 may be formed on the outer circumferential surface of the first screw 310 to transfer the bottle B from the second screw 320 to the turret assembly 200. The first alignment groove 311 may be formed in the shape of a spiral groove extending in the longitudinal direction of the first screw 310 on the outer circumferential surface of the first screw 310. Thus, the bottle B located at the inlet side of the first screw 310 is along the first alignment groove 311 by the rotation of the first screw 310, the turret assembly 200 at the second screw 320. It can be transferred to the idle path of (W).

The first screw 310 may be rotated by the first rotation shaft 360. The first rotation shaft 360 is a rotation pin 361 fixed to the first screw 310, a rotation bracket 362 rotatably connected to the first screw motor 331, the rotation pin 361 and the rotation It may include a joint 363 connecting between the brackets 362. When the rotation bracket 362 is rotated by the first screw motor 331, the rotational force of the rotation bracket 362 is transmitted to the rotation pin 361 through the joint 363, and the rotation force of the rotation pin 361 is zero. Since the first screw 310 is transferred, the bottle B positioned in the first alignment groove 311 of the first screw 310 may be transferred to the revolving path W of the turret assembly 200.

Here, the first screw 310 may be a hollow screw through which the second rotating shaft 370 of the second screw 320 penetrates, and the first rotating shaft 360 may be a hollow screw passing through the second rotating shaft 370. It may be a shaft. Accordingly, the second rotation shaft 370 of the second screw 320 may be operably connected to the first screw motor 332 through the first screw 310 and the first rotation shaft 360.

The second screw 320 may be positioned on the same extension line as the movement path of the in rail 110. The second screw 320 is disposed on the same line as the first screw 310, and may transfer the bottle B transferred from the in rail 110 to the first screw 310.

A second alignment groove 321 may be formed on an outer circumferential surface of the second screw 320 to transfer the bottle B from the in rail 110 to the first screw 310. The second alignment groove 321 may be formed in the shape of a spiral groove extending in the longitudinal direction of the second screw 320 on the outer circumferential surface of the second screw 320.

The second screw 320 may be rotated through the second rotation shaft 370. For example, one end of the second screw 320 may be fixed to the second rotation shaft 370 operably connected to the first screw motor 332, and the other end of the second screw 320 may be a bearing shaft 371. It can be fixed to.

In particular, since the first screw motor 331 and the first screw motor 332 are driven separately, the first screw 310 and the second screw 320 may be rotated independently of each other. For example, when only the first screw motor 331 is operated and the first screw motor 332 is stopped, since the first screw 310 is rotated, while the second screw 320 remains stopped, The bottle B located in the first alignment groove 311 of the first screw 310 may be transferred to the turret assembly 200 by the rotation of the first screw 310, but may be transferred to the turret assembly 200. The bottle B located in the second alignment groove 321 may be maintained in a stopped state.

The screw motor 330 may include a first screw motor 331 for rotating the first screw 310 and a first screw motor 332 for rotating the second screw 320. The first screw motor 331 may be rotatably connected to the end of the first rotation shaft 360 through the first drive belt 333, the first screw motor 332 through the second drive belt 334. It may be rotatably connected to an end of the second rotation shaft 370.

The position sensor 340 may detect rotation positions of the first screw 310 and the second screw 320. For example, the position sensor 340 measures the zero point at which the rotational positions of the first screw motor 331 and the first screw motor 332 match, and thus, the first alignment groove 311 of the first screw 310. The second alignment groove 321 of the second screw 320 can be detected to the point where the consecutive positions.

In the present embodiment, the zero point is a position where the first alignment groove 311 of the first screw 310 and the second alignment groove 321 of the second screw 320 are continuously disposed with each other. ) And the zero point of the second screw 320 may be set in advance before the operation of the bottle fill liquid inspection device.

The controller 350 operates the first screw motor 331 and the first screw motor 332 so that the first alignment groove 311 and the second alignment groove 321 are continuously disposed, so that the first screw 310 and The second screw 320 may be positioned at zero. In this case, since the first screw motor 331 and the first screw motor 332 operate in conjunction with each other, the bottle B supplied from the in rail 110 may be connected to the second screw 320 and the first screw 310. It may be moved to the idle path (W) of the turret assembly 200 via.

The controller 350 selectively drives the first screw motor 331 and the first screw motor 332 to rotate the first screw 310 in conjunction with the operation of the turret assembly 200, and the second screw ( 320) can be stopped.

That is, when a problem occurs in the process of accommodating the filling liquid in the bottle (B) or in the process of transferring the bottle (B) to the in-rail 110, the turret assembly 200 and the turret assembly 200 In the state where the operation of the first screw 310 is maintained, the operation of the second screw 320 may be stopped to selectively block the input of the bottle B supplied to the turret assembly 200. Then, when the problem is solved, the position sensor 340 measures the zero point, which is the position at which the rotational positions of the first screw motor 331 and the first screw motor 332 match, and provides the corresponding information to the controller 350. The controller 350 selectively drives the first screw motor 331 and the first screw motor 332 so that the first alignment groove 311 and the second alignment groove 321 are continuously positioned with each other. The screw 310 or the second screw 320 may be rotated.

If a problem occurs while the bottle B is transported through the in rail 110, while the operation of the turret assembly 200 is maintained, the double screw unit 300 moves to the turret assembly 200. Input of the bottle B to be supplied can be selectively blocked. That is, when a problem occurs in the transfer of the bottle (B), only a part of the configuration of the double screw unit 300 can be stopped without stopping the operation of the turret assembly 200, so that the entire process of the bottle filling liquid inspection device can be efficiently Can be operated.

When the bottle B enters the idle path W of the turret assembly 200, the bottle B is held by the gripper of the turret assembly 200, and the idle path W of the turret assembly 200 is maintained. Is idle along. In this process, the rotary unit 400 may rotate the bottle (B) at high speed so that centrifugal force is provided to the filling liquid contained in the bottle (B).

That is, as the turret assembly 200 rotates, when the bottle B held by the gripper comes into contact with the rotating belt 420 of the rotating unit 400, the bottle B is rotated by the rotating belt 420. Can be rotated at high speed. At this time, the gripper loosely holds the neck of the bottle B so that the rotation of the bottle B is smooth.

When the bottle B reaches the point where the test module 500 is located by the rotation of the turret assembly 200, the bottom tester 510 of the test module 500 changes the brightness of the light, while the inside of the bottle B is changed. Inspect the foreign body under the bottle (B).

For example, the first bottom inspector 510a may inspect a large foreign substance in the bottle B, and the second bottom inspector 510b may inspect a foreign substance such as glass powder in the bottle B. 3 bottom checker (510c) can inspect the foreign matter such as rubber.

Subsequently, the side checker 520 of the inspection module 500 may inspect the foreign matter from the side of the bottle B by using an infrared lamp, or examine the foreign matter by photographing the entire side of the bottle B.

When the inspection of the foreign matter through the inspection module 500 is completed, the bottle (B) may be discharged to the outside through the out rail 120.

As described above, in the present invention, when a problem occurs in the supply of the bottle containing the filling liquid, the supply of the bottle can be selectively blocked without stopping the entire system, and the foreign matter mixed in the filling liquid in the bottle is centrifugal force. By converging to the center by using, it has an excellent advantage such that the foreign matter in the bottle can be accurately and effectively inspected.
