2. Description of the Related Art A device for inspecting a bag-like container containing conductive and amorphous contents such as Ringer's solution, infusion solution, food and the like has been known. Such an inspection apparatus is disclosed in, for example, JP-A-62-38226.
A pair of electrodes are arranged above and below the conveying means for conveying the container, a high voltage is applied between the pair of electrodes, and a discharge current is generated on the container (test object) conveyed between the electrodes. The generated discharge current is detected to determine whether or not the current is acceptable.

In addition, since the inspection is performed using the fixed electrodes, it is impossible to accurately trace and inspect the entire portion requiring the inspection.

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned disadvantages, and an object of the present invention is to provide a container inspection apparatus capable of accurately tracing the entire inspection region of a container without fail.

[0005]

According to the present invention, there is provided a container inspection apparatus provided with a bucket for accommodating and transporting a container, a follower frame moving following the bucket, and an inspection station in a bucket transport path. A test electrode which can be moved up and down at a fixed position, and a cam which is provided on the following frame and which moves up and down the test electrode by engaging a cam follower attached to the test electrode.

[0006]

In the above inspection apparatus, the inspection is performed along the shape of the container by moving the cam to follow the bucket for accommodating and transporting the container and moving the inspection electrode up and down at a fixed position.

The roller 30 of the ground electrode 28 of the bucket C contacts a conductor 34a provided at a position on the guide rail 34 corresponding to the second inspection station S2. In the following, the roller 30 for each inspection station is
Contact 4a.

In the third inspection station S3, similarly to the second inspection station S2, positioning is performed by the top pusher T so that the inspection electrode D3 is in contact with the correct position of the infusion bag A. The upper surface A3 of the boat-shaped member AF is inspected.

At the fourth inspection station S4, when the infusion bag A is transported to a predetermined position, the electrode cylinder 160 of the fourth inspection mechanism K4 operates, and the infusion bag A
The inspection electrode D4 is brought into contact with the right shoulder A4 of. This electrode D
Reference numeral 4 moves in the transport direction following the movement of the infusion bag A. Next, the rotation cylinder 166 is operated to move the rack 17.
2 and the pinion 174 is rotated. The inspection electrode D4 moves along the curve of the shoulder A4 due to the rotation of the pinion 174. Note that, after the fourth inspection station S4, the bucket C is transported by the guide rail 34 in a horizontal state. Thereafter, when the fourth inspection mechanism K4 retreats, the inspection electrode D4 is raised by the electrode cylinder 160.

At the fifth inspection station S5, the inspection is performed by moving the electrodes along the left shoulder A5 of the infusion bag A in the same manner as the fourth inspection station S4.

When the infusion bag A is transported to the sixth inspection station S6, the electrode cylinder 206 is operated to bring the inspection electrode D6 into contact with a portion of the infusion bag A near the cap A1 on the side A6. While the sixth inspection mechanism K6 moves to follow the bucket C as a whole, the moving cylinder 1
Activate 92. The pinion 194 connected to the cylinder 192 meshes with the fixed rack 202,
Since it is also engaged with the moving rack 186, the pinion 19
4, the moving rack 186 has two strokes.
Double and move forward. As a result, the test electrode D6 can contact the entire long side surface A6 of the infusion bag A.

At the seventh inspection station S7, the left portion A7 of the infusion bag A is inspected in the same manner as the sixth inspection station S6.

When the bucket C is transported to a predetermined position of the eighth inspection station S8, the electrode cylinder 23
0 operates to bring the test electrode D8 into contact with a linear portion near the lower right corner A8 of the infusion bag A. Next, the moving cylinder 220 is operated to move the electrode D along the linear portion.
8 is moved linearly. When the stroke of the moving cylinder 220 reaches the corner A8, the cam follower 23
4 contacts the rotation cam 236, and rotates the rotation shaft 224. Thereby, the inspection along the corner portion A8 of the infusion bag A is performed. When the inspection mechanism K8 retreats, the electrode cylinder 230 is raised.

At the next ninth inspection station S9, the eighth
The lower left corner A9 is inspected by a ninth inspection mechanism K9 similar to the inspection station S8.

When the infusion bag A is conveyed to a predetermined position in the tenth inspection station S10, the electrode cylinder 242 is activated to operate the lower surface A10 of the bottom of the infusion bag A.
Is brought into contact with the inspection electrode D10. As the infusion bag A is transported, the electrode D10 comes into contact with the entire bottom lower surface A10. When the infusion bag A passes, the electrode D10 is separated by the electrode cylinder 242. Similarly, at the next eleventh inspection station S11, the upper surface A
Perform 11 tests. In the tenth and eleventh inspection stations S10 and S11, the inspection is performed with the infusion bag A slightly raised and inclined.

The first to eleventh inspection stations S
The infusion bags A sequentially inspected in 1 to S11 are discharged from the bucket C onto the unloading conveyor 12 or the reject conveyor 14 by the carrier pushing device 10 in the discharging section. If the inspected infusion bag A finds a pinhole or the like at any of the inspection stations, the reject conveyor 1
4 and other normal infusion bags A are pushed out on the carry-out conveyor 12.
