 Various rubber rollers with a rubber layer on the surface are used in the internal mechanism of 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 that applies a grinding wheel to the surface of the rubber roller for grinding is used. The grinding process of the rubber roller is fully automatic from the supply to the discharge, and the outline of the device will be described with reference to FIGS. 4 and 5. In these figures, reference numeral 1 denotes a grinder, and although the internal mechanism of the grinder 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 chuck part 4 and a movable chuck part 5, and the movable chuck part 5 is configured to be movable in the vertical direction in FIG.

The table 6 provided on the upper surface of the grinder 1 is configured to be able to reciprocate in the direction of arrow A shown in FIG. 1 after the rubber roller 2 is gripped by the chuck device 3. Reference numeral 7 denotes a grindstone for grinding, which moves in a direction perpendicular to the rubber roller 2 by a slide mechanism (not shown) to grind the surface of the rubber roller 2 gripped by the chuck device 3. Reference numeral 8 is a positioning cylinder, and when the rubber roller 2 is placed on the positioning cylinder 8 by a rodless cylinder described later, the chuck device 3 automatically chucks the rubber roller 2.

Reference numeral 9 denotes an autoloader for conveying the rubber roller 2 to the grinder 1 and has the following configuration. That is, as shown in FIG. 5, the autoloader 9 includes a supply conveyor 11 in a frame 10, and the rubber roller 2 is supplied from a position above the supply conveyor 11 to a supply table 12 that moves up and down in the frame 10. Has become. A rodless cylinder 14 having a gripping arm 13 is provided immediately above the supply table 12. This rodless cylinder 14 grips the rubber roller 2 on the supply table 12 by the gripping arm 13, conveys the rubber roller 2 to the grinder 1 by moving in the horizontal direction as shown by an arrow B, and after finishing the grinding work, It serves to convey the rubber roller 2 that has been finished 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 having the above-described configurations will be described. First, when the rubber roller 2 is supplied to the supply base 12 by the supply conveyor 11 of the autoloader 9, the supply base 12 places the rubber roller 2 thereon, moves upward, and stops at a predetermined position. Then, 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 grinder 1 side by the movement of the rodless cylinder 14 in the horizontal direction (direction of arrow B). Next, when the rubber roller 2 is placed on the positioning cylinder 8 on the grinder 1 side, the shaft portion of the rubber roller 2 is chucked by the chuck device 3.

Next, the grindstone 7 of the grinder 1 advances to grind the surface of the rubber roller 2. At this time, the table 6 itself supporting the rubber roller 2 moves in the direction perpendicular to the grinding wheel 7 (direction of arrow A), and grinding is performed over the entire axial direction of the rubber roller 2. The rubber roller, which has finished grinding in this way, is conveyed again to the discharge table 15 of the auto loader 9 by the rodless cylinder 14 and releases the finished rubber roller 2 on the discharge table 15.

[Problems to be solved by the device]

 By the way, the autoloader 9 that conveys the rubber roller 2 to the grinder 1 has the following problems to be solved. That is, when the rubber roller 2 falls on the supply table 12 from the end of the supply conveyor 11, the rubber roller 2 is displaced in either the left or right direction of the supply table 12. Therefore, the gripping arm 13 is not gripped at the regular position, is conveyed to the positioning cylinder 8 via the rodless cylinder 14, and is placed on the positioning cylinder 8 1 in a positionally displaced state. In this case, either the left or right of the rubber roller 2 may come off the positioning cylinder 8 and drop onto the table 6. Therefore, the rubber roller 2 is not chucked by the chuck device 3. In order to remove the fall roller 2, it was necessary to stop the operation of the machine each time, which was a cause of lowering work efficiency. The present invention has been made to solve the above problems, and can correct the misalignment of the rubber roller on the supply table to a regular position and accurately mount it on the positioning cylinder, thus ensuring continuous machine operation. It is an object of the present invention to provide a position correction device for an autoloader that can achieve high efficiency by operation.
