Abstract

PURPOSE:To prevent deformation and skewing of a sheet material by disposing a pair of idler rollers bisymmetrically about the center line extended in the direction of transporting a sheet material and making the respective rotating directions point outward with respect to the above center line. CONSTITUTION:When a driving roller 2 is driven, the driving force is transmitted to a belt 1 mounted on the roller, so that a sheet material 6 is clamped between the belt 1 and an idler roller 3 and transported in direction of an arrow A. In this case, at least a pair of idler rollers 3 are disposed bisymmetrically about the center line L extended in the direction of transporting a sheet material 6, and the rotating directions of these rollers 3 are pointed outward with respect to the above center line L. In this arrangement, the sheet material 6 is transported in direction of an arrow C toward the left and right outside, so that the material 6 is expanded to correct deformation.

A roller mechanism is used that clamps and conveys the monthly paper between an idler roller and an idler roller1.Here, in the conventional roller mechanism, the rotating direction of the idler roller is aligned with the driving belt or the driving roller. In other words, it was configured to be parallel to the conveyance direction of the sheet-like monthly fee. However, in such a roller mechanism, even if wrinkles or skew (diagonal feeding) occur in the sheet-like material, these phenomena are not corrected, but rather these phenomena are exacerbated. In particular, if the finished diameter of the rollers varies or the assembly of the device is incomplete, the roller mechanism itself can cause wrinkles and smudges in the sheet material. It is an object of the present invention to provide a mechanism for conveying sheet-like materials, which can eliminate the above-mentioned drawbacks of the device and can normally convey sheet-like materials along a predetermined direction.

である。Structure of the Invention The above-mentioned object of the present invention is to provide a sheet-shaped paulownia 1/+ conveyance roller mechanism for conveying a sheet-like material by sandwiching the sheet-like material between a driving belt or roller and an idler roller. This is achieved by configuring the roller differently from conventional ones. That is, the roller for conveying the sheet-like fee of the present invention has the following feature: 't4'& characteristics That is.

A driving belt 1 is attached to the r1-r 2 for 1liJ, and the sheet-shaped royalty is held between this belt and the idler roller 3 and is conveyed. Unlike the case shown in the figure, the driving belt 1 may be omitted and the sheet material may be held between the driving roller and the idler roller. Note that 6 is a baffle Z) that completely prevents the sheet material from protruding upward, but it may be omitted if necessary.

In Figure 1, the direction of conveyance of the sheet material is Although only one pair of sheet ropes at both ends of the front and rear sections are specifically illustrated, the number of sheets depends on the size (width, length) of the sheet material to be conveyed.
:, can be selected as appropriate. (For the middle 11U idler roller, only its axial and rotational positions are shown by lines.) Also, the idler roller may be provided with an idler roller 4 if necessary. . Generally, it is preferable that the outward angle of the sea roller relative to the center line LK is about /50.

殆んど起こらなくなる。When the roller mechanism of the present invention configured as described above is operated, the driving roller 2 is driven to rotate, and a driving force is transmitted to the belt 1. 3, while being conveyed in the direction shown in the figure. At this time, even if the sheet-like material has deformation such as wrinkles, the material is stretched out and the deformation is corrected because the idler roller tries to convey it from side to side in the C direction. Even if a skew state occurs in the monthly interest rate, the idler loan can reduce the skew state due to the force pulling outward from the left and right sides σI. Furthermore, even if the two-gage pressure that holds the sheet-like interest is uneven due to an uneven finish on the rollers, a force that balances the material at 1° during conveyance is applied, which prevents skew and Phenomena such as deformation hardly occur.
