2. Description of the Related Art Various rubber rollers having a rubber layer on the surface are used in internal mechanisms such as copying machines. In order to finish the smoothness of the surface of the rubber roller or the roundness of the rubber layer with high accuracy, a grinder for grinding by applying a grinding wheel to the surface of the rubber roller is used. The grinding process of the rubber roller is performed fully automatically from supply to discharge, and an outline of the apparatus will be described with reference to FIGS. In these figures, reference numeral 1 denotes a grinding machine, and although the internal mechanism of the grinding machine 1 is omitted, a chuck device 3 for supporting the rubber roller 2 is provided on the upper surface of the table 6. The chuck device 3 includes a fixed-side chuck portion 4 and a movable-side chuck portion 5, and the movable-side chuck portion 5 is configured to be movable in a direction indicated by an arrow A in FIG. 4 .

The table 6 provided on the upper surface of the grinding machine 1 is configured to be able to reciprocate in the direction of arrow A shown in FIG. 4 after the rubber roller 2 is gripped by the chuck device 3.
Reference numeral 7 denotes a grinding wheel, which is moved in a direction perpendicular to the rubber roller 2 by a slide mechanism (not shown) to grind the surface of the rubber roller 2 held by the chuck device 3. Reference numeral 8 denotes a positioning cylinder, which is a mechanism by which the rubber roller 2 is automatically chucked by the chuck device 3 when the rubber roller 2 is mounted on the positioning cylinder 8 by a rodless cylinder described later.

[0004] Reference numeral 9 denotes an autoloader for conveying the rubber roller 2 to the grinding machine 1 and has the following configuration. That is, as shown in FIG.
0, a supply conveyor 11 is provided.
The rubber roller 2 is supplied onto a supply table 12 that moves up and down in the frame 10 from above. A transfer mechanism 14 composed of a rodless cylinder having a gripping arm 13 is provided directly above the supply table 12. The rodless cylinder 14 constituting this transport mechanism grips the rubber roller 2 on the supply table 12 by the gripping arm 13 and moves the grinding machine 1 in the horizontal direction as shown by the arrow B.

It serves to transport the finished rubber roller 2 to the discharge table 15 of the autoloader 9.

Next, an outline of a grinding process of the rubber roller 2 using the grinding machine 1 and the autoloader 9 configured as described above will be described. First, when the rubber roller 2 is supplied to the supply table 12 by the supply conveyor 11 of the autoloader 9, the supply table 12 mounts the rubber roller 2 and rises upward, and stops at a predetermined position. Next, the rubber roller 2 is gripped by the gripping arm 13 of the rodless cylinder 14, and the rubber roller 2 is conveyed to the grinding machine 1 by the horizontal movement (the direction of arrow B) of the rodless cylinder 14. Then
When the rubber roller 2 is placed on the positioning cylinder 8 on the grinding machine 1 side, the chuck unit 3 chucks the shaft of the rubber roller 2.

Next, the grinding wheel 7 of the grinding machine 1 advances and grinds the surface of the rubber roller 2. At this time, the table 6 itself that supports the rubber roller 2 moves in a direction perpendicular to the grinding wheel 7 (the direction of the arrow A), and grinding is performed over the entire rubber roller 2 in the axial direction. The rubber roller that has been ground in this manner is again transported to the discharge table 15 of the autoloader 9 by the rodless cylinder 14, and the finished rubber roller 2 on the discharge table 15 is released.

[0007]

The autoloader 9 for transporting the rubber roller 2 to the grinding machine 1 has the following problems to be solved. That is, supply conveyor 1

Is positioned in the direction of its axis.
And it will be placed on the top 8. Such axial displacement
If the rubber roller 2 is fed to a predetermined position in a state in which the rubber roller 2 is moved, one of the right and left sides of the rubber roller 2 is disengaged from the positioning cylinder 8 , and the rubber roller 2 may drop onto the table 6. Therefore, the rubber roller 2 is not chucked by the chuck device 3. In order to remove the dropped rubber roller 2, the operation of the machine must be stopped each time, which causes a reduction in work efficiency. The present invention has been made in order to solve the above-described problems, and can correct the displacement of the rubber roller on the supply table to a regular position, and can accurately mount the rubber roller on the positioning cylinder.
It is an object of the present invention to provide a position correcting device for an autoloader that can achieve high efficiency by continuous operation of a machine.
