Description

  The present invention provides, for example, a roller shaft parallel holding device capable of performing the mounting and fixing operation in a state where the rollers are held so that the axial directions of the rollers are parallel to each other when, for example, a plurality of rollers are mounted and fixed at predetermined roller mounting positions The present invention relates to a roller mounting method using this roller shaft parallel holding device.

  Conventionally, various sheet conveying apparatuses for conveying a sheet material such as a thin film or a tape have been proposed. In these, a plurality of conveying rollers are arranged in the conveying direction so that their rotation axes are parallel to each other, and the rollers are conveyed in a predetermined conveying direction while applying tension to the sheet material.

  Therefore, if the rotation axes of the rollers are not parallel, extra tension in the lateral direction (width direction) is applied to the sheet material tensioned between the rollers, which twists and distorts the sheet material being conveyed. As a result, this causes a problem such as damage or deformation of the sheet material.

  Therefore, when using this type of sheet conveying apparatus, the operation of setting each roller to be mounted and fixed on the conveying apparatus main body by appropriately adjusting the mounting position and orientation of the rollers and setting the rotation axes of the rollers to be parallel to each other. Is essential.

  In general, the setting operation is performed by setting the rotation shaft of a roller to be attached and fixed to the transport apparatus main body horizontally using a level or the like, and then one roller (fixed side roller) fixed in advance to the transport apparatus main body. The rotation shaft of the other roller (adjustment side roller) is set in parallel with the rotation shaft of), and the adjustment side roller is attached and fixed to the main body of the transport apparatus. Specifically, by using a length measuring device or the like, the distance between the one end of the fixed roller and the one end of the adjusting roller and the distance between the other end of the fixed roller and the other end of the adjusting roller are uniformly adjusted. The rotating shafts of both rollers are set in parallel, and the adjustment side roller is attached and fixed. By sequentially repeating this setting operation, a plurality of rollers are attached and fixed to the main body of the conveying device one after another so that their rotational axes are parallel to each other.

  By the way, in this type of sheet conveying apparatus, as means for fixing and fixing the roller to the main body of the conveying apparatus, for example, fastening and fixing means using fasteners such as bolts and nuts (for example, mounting holes through which the bolts are inserted are provided on the apparatus side and the rollers. The bolts are inserted and fastened with nuts, and the mounting holes on either the device side or the roller side are long holes, and the bolts move through these long holes. In a possible range, it is common to move and adjust (parallel adjustment) the roller mounting and fixing position with respect to the main body of the conveying device and fasten and fix it at a predetermined position.) Due to slight misalignment, misalignment was apt to occur when the roller was fixed. Therefore, for example, even if one end side of the roller is attached and fixed to the conveyance device main body, and the attachment position on the other end side is corrected by the amount of deviation of the attachment and fixing position on the one end side, the other end is eventually fixed. Since the above-mentioned positional deviation also occurs when mounting and fixing the side, the roller should be mounted and fixed in the desired axial direction of the rotating shaft (that is, the axial direction parallel to the rotating shaft of the other roller). Was difficult.

  Even if the axial deviation of the rotation axis of this roller is very small, the conveyed sheet material is surely given extra tension that causes twisting and distortion, and troubles such as breakage and deformation of the sheet. The effect is great.

  Therefore, until now, when performing the setting work of the roller, the deviation is gradually corrected while repeatedly attaching and removing the roller one end side and the other end side to the main body of the conveying device many times. Since the operation of aligning the rotation axis of the roller with the appropriate axial direction was performed, the workability was very poor, and it was a very troublesome work requiring high skill, a lot of time, labor and cost.

  For example, in this type of sheet conveying apparatus, a type having a function of automatically correcting the rotation axis of the roller in an appropriate axial direction has been proposed, for example, Japanese Patent Laid-Open No. 2002-255421. Has a function of correcting the rotation shaft in an appropriate axial direction so that the bearing portion that rotatably supports the end portion of the rotation shaft of the roller swings and no extra tension is applied to the sheet material. Has been disclosed.

  However, the type that automatically corrects these axial directions inevitably has a complicated structure, so it is not only inferior to the productivity of the device itself, but also significantly increases the cost compared to the above general type. There are problems and it is not practical.
