Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a rotary foreign substance inspection machine for inspecting foreign substances floating in a liquid of an article or adhering to a wall or the like. Is.

[Conventional technology]

Conventionally, as shown in FIGS. 4 and 5, the rotation mechanism of an article as a sample in a rotary foreign matter inspection machine for inspecting foreign matter floating in a liquid of an article or adhering to a wall or the like is as shown in FIGS. ,
A belt 6 having a round cross section wound around a drive pulley 4 and a driven pulley 5 rotated by a drive source 3 such as a drive motor is pressed against a plurality of sample trays 2 rotatably supported on a moving table 1. The specimens placed on the specimen trays 2 are inspected while the specimen trays 2 are brought into contact with each other and the rotation is simultaneously transmitted to the respective specimen trays 2 to move the specimen trays 2 together with the table 1.

[Problems to be solved by the device]

However, in the conventional rotation mechanism of the sample tray 2,
The sample tray 2 was an obstacle, and the belt 6 could not be strongly pressed against the sample tray 2, which was remarkable especially when the number of the sample trays 2 simultaneously rotating was small.

Therefore, the sample tray 2 and the belt 6 easily slip,
There is also a problem that accurate rotation (rotational speed, intermittent drive, etc.) cannot be transmitted to the sample tray 2, and fine powder is generated due to abrasion due to slip.

The present invention solves the above-mentioned drawbacks of the related art, accurately transmits the rotational force on the driving side to the sample tray 2, and allows a smooth inspection without disturbing the movement of the sample tray 2. The purpose is to provide a machine.

[Means for Solving the Problems]

According to the present invention, a plurality of sample pans 2,2 ...
... are rotatably supported, and rollers 7 are coaxially provided on the respective sample trays 2, and a swing lever 11 is swingably supported near the table 1 to swing the swing lever 11. Pulleys 9 and 12 are rotatably attached to the position corresponding to the center of motion and the tip, and the belt 6'is hung.
The pulley 9 is connected to the drive source 3, a drive roller 13 that rotates integrally with the pulley 12 is attached to the tip of the swing lever 11, and the swing lever 11 is connected to the swing roller 11.
A spring 15 and a stopper 16 for urging the drive roller 13 in a direction in which the drive roller 13 contacts the roller 7 are provided, and the drive roller 13 is elastically sequentially moved to one of the rollers 7 moved by the table 1. The rotary foreign matter inspection machine is characterized in that the sample tray 2 is rotated by pressing.

[Action]

In the present invention having the above-mentioned configuration, the swing lever 11 is biased in one direction by the spring 15, and the drive roller 13 provided on the swing lever 11 is pressed against the roller 7 of one sample tray. If you rotate the drive roller 13,
The rotation is accurately transmitted to the roller 7 and the sample tray 2
Is rotated, and the foreign matter inspection of the sample placed on the sample tray 2 is performed.

After the inspection, the sample tray 2 moves together with the table. At that time, the roller 7 of the sample tray 2 pushes the driving roller 13 together with the swing lever 11 against the elastic force of the spring, and the sample tray 2 moves. After that, the rocking lever 11 is restored by the spring 15 and is pressed against the roller 7 of the next sample tray 2, and the sample tray 2 is rotated.

The swing lever 11 is provided with a pulley 9 at a position corresponding to the swing center on the base end side to communicate with the drive source 3, and a pulley 12 that rotates integrally with the drive pulley 13 on the tip end side.
Is provided and the power of the drive source 3 is transmitted to the drive pulley 13 by the belt 6'wound between the pulleys 9 and 12, so that the drive pulley 13 of the swing lever 11 can be widely separated during maintenance or the like. Therefore, the maintenance work is easy, and the pressing force of the drive pulley 13 can be adjusted not only by changing the spring constant of the spring 15 but also by changing the fixing position, which is easy to adjust.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. A roller 7 is coaxially fixed to a sample tray 2 which is rotatably supported by a movable table 1. ing.

As a rotation mechanism of the sample tray 2, a pulley 9 is fixed to a rotary shaft 8 of a driven pulley 5 that is transmitted via a belt 6 by a drive pulley 4 that is rotated by a drive motor that is a drive source 3. 9 is rotatably supported on a support shaft 10, one end of a swing lever 11 is swingably held on the support shaft 10, and a pulley 12 is provided at the tip of the swing lever 11. A belt 6'is wound around the pulleys 9 and 12 so that the pulley 12 rotates together with the rotation of the pulley 9, and the pulley 12 is fixedly provided with a drive roller 13 coaxially attached with rubber on the outer periphery. ing.

Further, the other end of the spring 15 whose one end is held by the support base 14 is attached to the swing lever 11, and the swing lever 11 is always pulled in the direction of the support base 14 (right direction in FIG. 1).
The drive roller 13 at the tip of the swing lever 11 is biased so as to be elastically pressed against the roller 7 of the sample tray 2.

In the figure, reference numeral 16 denotes a retractable stopper provided on the support base 14 for adjusting the range in which the swing lever 11 is pulled by the spring 15, and 17 is an article placed on the sample tray 2 to be inspected. Shows the sample that is.

Then, the rocking lever 11 is pulled by the spring 15, the driving roller 13 at the tip thereof is pressed against the roller 7 of the sample tray 2, and the driving source 3 drives the driving pulley 4, the belt 6, the driven pulley 5, the pulley 9, The rotation is transmitted to the pulley 12 via the belt 6 ', the roller 7 is rotated by the driving roller 13 rotating together with the pulley 12, the sample tray 2 is rotated, and the sample 17 is inspected.

After such an inspection, the table 1 is moved to move the sample tray 2 after the inspection. At that time, the roller 7 of the sample tray 2 pushes the driving roller 13, and the swing lever 11 pulls the spring 15 with a pulling force. The sample tray 2 is moved away from the sample, and then the swing lever 11 is restored by the spring 15 to the position of the stopper 16 as shown by the chain line in FIG. 1, and the drive roller 13 is moved to the next sample. It is pressed against the roller 7 of the tray 2 to rotate the sample tray 2 as described above.

At the time of maintenance, the swinging lever 11 is swung counterclockwise in FIG.
However, the maintenance work is easy because it is largely separated from the table 1, and the pressing force of the drive roller 13 against the roller 7 can be easily adjusted.

[Effect of device]

As described above, according to the present invention, since the drive roller rotated by the drive source is elastically pressed by the spring to the roller fixed to the sample tray, the rotation of the drive roller is accurately transmitted to the roller of the sample tray. It also prevents the generation of fine powder without causing slipping, etc., and when the sample tray is moved, the drive roller is pushed away by the movement of the sample tray itself, and after the sample tray is moved, the drive roller is restored by the spring and the next sample tray is moved. Therefore, the foreign matter of the sample can be smoothly inspected, and the maintenance work can be easily performed by largely separating the drive roller from the table, and the pressing force can be easily adjusted.
