In FIG. 1, a package inspection apparatus 1 of the present invention penetrates through the entire apparatus and is provided with belt conveyors 3 and 4 to form a conveying path 2, and along the conveying path 2, a yarn end processing station 11, A waiting station 12, a first inspection station 13, a second inspection station 14, and a weight measuring station 15 are provided.

Of the above stations, the standby station 12, the first inspection station 13, and the second inspection station 14 are formed inside the frame 5 by covering the periphery of the frame 5 with a light shielding material (not shown). Is located in the dark room 6 and has an inlet 7 and an outlet 8 of the dark room 6.
Light-shielding doors 9 and 10 for shielding the opening portions are provided in each. The light shielding doors 9 and 10 are trays T which are conveyed by the belt conveyor 3 in a state in which the package P is inserted upright.
It is opened on both sides by being pushed by, and is closed by the restoring force of a spring (not shown) when the tray T passes.

The first inspection station 13 is a station for carrying out a traverse inspection of the package P, a contamination inspection, and a heterogeneous mixture inspection. The first station 13 includes:
The black lights 33 and 34 for irradiating the package P located in this portion with ultraviolet light obliquely above and below the package P, the halogen lamp 35 for irradiating visible light, and the package P above and obliquely above and below the package P, respectively. CCD cameras 31 and 32 for monitoring from obliquely below are provided.

The second inspection station 14 is a station for performing a shape defect inspection such as a step winding and a kiku winding of the package P, and a bunch winding defect inspection. The second station 14 has the package P directly above. A CCD camera 41 for monitoring, a CCD camera 42 for monitoring the base end bunch winding part of the package P almost directly from the side, and a halogen lamp 4.
Although not shown in the drawing, a halogen lamp 4 is provided below the CCD camera 42 to irradiate the bunch winding portion with visible light.

Then, each station 11, 12, 1
A stop device (not shown) for stopping and positioning the tray T is provided at the portions 3 and 14, and a roller 16 for rotating the stopped tray T is provided at the yarn end processing station 11 and the first inspection station 13. , 17 and motors 18 and 19 for driving and rotating the rollers 16 and 17, respectively. A weight scale 20 is provided on the lower surface of the belt conveyor 4 of the weight measuring station 15.

Next, a package inspection process will be described based on an embodiment.

The package P is mounted on the belt conveyor 3 while being inserted into the tray T, and the package P is installed in the inspection device 1 as shown in FIG.
After being transferred from the middle right end, stopped and positioned at the yarn end processing station 11, the tray T is rotated by being pressed against a roller 16 rotated by a motor 18 and rotated, whereby the yarn end is brought into contact with the surface of the package P by means not shown. Wrapped around. This is to prevent the occurrence of an error due to a frayed yarn end in a later inspection.

The package P which has been subjected to the above processing is transferred by the belt conveyor 3, and the tray T pushes the light-shielding door 9 of the entrance 7 to enter the dark room 6 and stops at the waiting station 12 and stands by.

Next, the package P in the standby station 12 is transferred by the belt conveyor 3, stopped by the first inspection station 13 and positioned, and then the tray T is pressed against the tray 17 by the roller 17 rotated by the motor 19. Then, while rotating the package P together with the tray T, the reflected light and fluorescence from the surface of the package P are CC
By performing image pickup with the D cameras 31 and 32 and analyzing the obtained light information, the cross-cutting inspection, the different kind mixture inspection, and the dirt inspection are performed.

The package P which has completed the above-mentioned inspections is transferred to the second inspection station 14 by the belt conveyor 3, and is transferred by the CCD cameras 41 and 42 by the same means as the inspection in the first inspection station 13 described above. A shape defect inspection such as a winding and a Kikumaki winding and a bunch winding defect inspection are performed. Then, the package P that has completed these inspections
While being conveyed by the belt conveyor 3, the tray T pushes open the light-shielding door 10 at the exit 8 and exits the dark room 6, and is conveyed to the weight measuring station 15, where the weight of the package P is measured by the weight scale 20. To be measured.

The above-described inspection process is all performed in parallel and continuously. For example, the inspection process of the package P in the first station 13 is completed, and the package P is transferred to the next second station 14. In parallel with the above, the package P in the front standby station 12 is
It is transferred to the station 13 and undergoes inspection processing.

In particular, the CDD camera 32 is located on the obliquely front side of the first inspection station 13 while avoiding the black lights 33 and 34, and the entrance 7 has the light-shielding door 9. Although it is impossible to provide the first inspection station 13 in the vicinity of the entrance 7, since the standby station 12 is provided between the first inspection station 13 and the yarn end processing station 11 on the front side thereof, The package P can be immediately transferred from the waiting station 11 to the first station 13 which requires a certain inspection time. Further, the interval between the yarn end processing station 11 and the standby station 12 is longer than the other intervals, but the standby station 12 naturally does not require a processing time, and therefore each station 11, 12,
The inspection processing time at 13, 14, and 15, that is, the time obtained by adding the movement time between stations to the actual inspection time is shortened and balanced.

As a result, the inspection processing capability is greatly improved as compared with the time required for one package P to pass through the entire inspection process. Also, the waiting station 1
By providing 2, the CCD camera, the halogen lamp and the like can be set relatively freely.

In the above-mentioned embodiment, the standby station 12 is provided immediately before the first inspection station 13 for carrying out the twill inspection, the different kind mixture inspection and the dirt inspection, but the present invention is not limited to this. It is not limited, and it should be added that the standby station may be provided in front of another station, and a plurality of standby stations can exist.

[0023]

As described above, according to the package inspection apparatus of the present invention, in the package inspection apparatus having a plurality of inspection stations in the package conveyance path, the standby station is provided immediately before at least one inspection station. The inspection processing time can be shortened and the processing capacity can be improved by increasing the transfer time between the inspection stations.
