Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling device, and more particularly, to a filling device having a filling portion for continuously transporting and filling containers in a clean room and a sealing portion for sealing the containers.

[0002]

2. Description of the Related Art In order to fill a product with high sterility, a filling device for performing a container filling process and a sealing process in a clean room and performing other inspection processes and the like outside the clean room in order to fill a product having high sterility has been developed. Are known.

[0003]

However, such a filling apparatus has the following problems. First, even when a filling failure or a sealing failure occurs in an early process of a clean room, the entire process of the clean room is performed. For example, the sealing process is performed despite insufficient filling. Second, even if incomplete processing is performed in the early stage of one process, the subsequent processing becomes complete in appearance, and the subsequent inspection cannot find the defect. That is, for example, even if the cap for sealing is temporarily improperly tightened, when the cap is fully tightened, it looks as if the predetermined final tightening has been performed. In other words, if a cap is used in which the sealing means engaging with the upper end of the mouth portion of the container is formed on the inside of the top surface, if the cap is improperly temporarily tightened, the cap may be moved to the mouth portion of the container. When the temporary tightening is completed, the upper end of the mouth portion of the container, which should have been engaged, and the sealing means inside the cap are not properly engaged when the temporary fastening is completed. A condition may occur. When the final tightening is performed in such a state, the cap is screwed to a predetermined position of the mouth portion of the container by the large torque of the final tightening device, but the tip of the mouth portion of the container and the sealing means inside the cap are screwed. The seal between them may be incomplete, resulting in a defective product in which the contents leak.

Third, it is preferable to dispose a container elimination device in a clean room in order to eliminate a defective product immediately after it is detected. However, if such a device is configured, the container may fall over or foreign matter may enter the container. Problem may occur. The conventional device for detecting and eliminating a container detected as a defective filling or poor sealing in a clean room by a combination of a synchro line (transport screw) and an encoder has a problem that the structure is complicated and control is difficult.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional filling apparatus, and eliminates unnecessary and unnecessary steps in a clean room when a defective process is performed in a process in a clean room. The purpose is to provide. Another object of the present invention is to provide a filling device that can perform an inspection immediately after each process in a clean room and reliably detect a processing defect that is covered by a subsequent process. . Another object of the present invention is to provide a filling device having a simple structure, which can easily and surely detect and remove a container detected in a clean room outside the clean room.

The temporary fastening member 1 is further urged by a built-in spring means 8 toward the cap 3 covering the mouth of the conveyed container, so that the temporary fastening surface 1a is provided. And the support surface 2a are arranged so as to sandwich the outer peripheral surface of the cap 3 over the mouth of the container B conveyed on the conveying line L, so that the container conveyed on the conveying line L Cover the mouth of B The cap 3
Moves between the temporary fastening surface 1a of the temporary fastening member 1 and the support surface 2a of the cap support member 2 while pushing the temporary fastening member 1 away from the transport line L against the urging force of the spring means 8. Then, while being held between the temporary fastening surface 1 a of the temporary fastening member 1 and the support surface 2 a of the support member 2, it moves in the direction of the arrow a along the transport line L.

Since the temporary fastening member 1 is urged in the direction of the cap support member 2 by the spring means 8, the cap 3 is pressed by a predetermined pressing force of the spring means 8.
While being clamped between the cap B and the cap support member 2, the cap B moves in the direction of the arrow a, is rotated clockwise with respect to the container B, and is screwed into the spiral thread S provided at the mouth of the container B. Then, the temporary fastening step is completed. Next, the container B with the cap 3 temporarily fastened is transported along the transport line L between the judging means provided with the light emitting section 4 and the light receiving section 5.
Here, when the light emitted from the light emitting unit 4 is blocked by the temporarily fastened cap 3 and does not reach the light receiving unit 5, the cap of the container B passing between the light emitting unit 4 and the light receiving unit 5 is closed. It is determined that the temporary fastening is insufficient or inappropriate, and a marking is provided on the top surface of the cap 3 of the container B by the marking means 6 provided downstream of the determination means. When the light emitted from the light emitting unit 4 is not blocked by the temporarily tightened cap 3 and reaches the light receiving unit 5, the cap of the container B passing between the light emitting unit 4 and the light receiving unit 5 is temporarily stopped. It is determined that the tightening is sufficient and appropriate, and the marking means 6 provided downstream of the determining means does not operate. Next, the container, for which the temporary fastening has been completed, is subjected to final fastening of the cap by a final fastening device (not shown).

The container provided with the light-emitting portion 4 and the light-receiving portion 5 and having determined that the temporary fastening is inappropriate or insufficient and marked on the top surface of the cap 3 is identified by the exclusion device.
