Description

[Detailed Description of the Invention] This invention relates to a roller shaft support structure when a roller is installed between opposing fixed walls.

For example, when the above-mentioned roller has an elongated shape, bearing holes for supporting the shafts at both ends of the roller are formed in the opposing fixed walls, but if the center of this hole is misaligned, , a large load will be applied to the bearings installed in each part, which will have an adverse effect such as significantly shortening the life of the bearings.Also, the positional deviation of the forming hole mentioned above is also caused by distortion of the fixed wall, so the forming hole The problem could not be solved even if the precision of the formation was increased.

Therefore, the object of this invention is to provide a support structure for a roller shaft that can absorb the misalignment of the hole formed in the fixed wall and provide a good bearing even if the hole formed in the fixed wall is misaligned in supporting the roller shaft as described above.

According to this invention, one roller shaft is pivoted to one fixed wall via a bearing, and the other roller shaft is freely pivoted to the other fixed wall via a bearing, so that the fixed wall Even if a positional shift occurs in the formed hole, this can be absorbed by the above-mentioned movable structure.This eliminates the load on the bearing due to the positional shift of the formed hole, extending the life of the bearing and shaft. Can be done.

An embodiment of this invention having such characteristics will be described in detail below based on the drawings.

The drawings show a collection roller installed at the entrance of a collection box that prints transaction details and collects issued slips in an automatic transaction device used in banking. A collection roller 2 is disposed below the entrance of the box, and a suppression roller 3 is provided above the collection roller 2. When the collection roller 2 is rotated in the collection direction, the slip is placed in the collection box. 1 will be collected.

The above-mentioned collection roller 2 has a drive section 4 implanted and fixed at one end thereof, this drive shaft 4 is supported by one fixed wall 6 via a bearing 5, and a one-way clutch 7 is connected to the shaft end. A transmission gear 8 is attached therebetween.

The one-way clutch 7 described above transmits power when the transmission gear 8 rotates in the recovery direction, and becomes free when the transmission gear 8 rotates in the opposite direction.

Incidentally, power is transmitted to the above-mentioned transmission gear 8 from an appropriate drive track system.

On the other hand, a fixed shaft 10 is attached to the other end of the collection roller 2 via a one-way clutch 9, and the free end of this fixed shaft 10 is formed with a large diameter, and the opposing surfaces are cut to form a detent shape 11. This is fitted into a detent hole 13 formed in the other fixed wall 12 facing the fixed wall 6 described above.

The above-mentioned detent shape 11 and detent hole 13 are designed to allow the detent shape 11 to freely move, that is, to be able to freely move up and down and left and right so that misalignment of the axes between the fixed shaft 10 and the drive shaft 4 can be absorbed. They are fitted with a gap 14 formed therebetween.

Note that the one-way clutch 9 mentioned above becomes free rotation when the drive shaft 4 rotates in the recovery direction, and enters a power transmission state when the drive shaft 4 rotates in the opposite direction, but since the fixed shaft 10 is fixed, As a result, rotation of the collection roller 2 is prevented.

When the power in the recovery direction is transmitted to the aforementioned transmission gear 8,
The drive shaft 4 is driven via the one-way clutch 7, the collection roller 2 is rotated in the collection direction, and the supplied slips are collected.

When rotation in the opposite direction is transmitted to the transmission gear 8, the one-way clutch 7 becomes free and no power is transmitted, and the other one-way clutch 9 is connected to the collection roller 2.
is in a state that prevents it from rotating in the opposite direction, and the slip is placed in collection box 1.
This prevents the material from being taken out in the opposite direction.

In addition, since one of the fixed shafts 10 of the collection roller 2 can freely move vertically and horizontally due to the free movement gap 14, the axle positions of the shafts 4 and 10 may shift due to distortion of the fixed walls 6 and 12. Provides smooth rotation.

FIG. 5 shows another example of the support of the fixed shaft 10 in the first embodiment. 15 is attached to the fixed wall 12 having a hole 17 with screws 18, and the free movement of the fixed shaft 10 in this case is obtained by the elasticity of the leaf spring material 15.

FIG. 6 shows another embodiment in which one shaft end has free movement, and a fixed shaft 10 is implanted and fixed at one end of the collection roller 2.
The one-way clutch 9 mounted on the fixed shaft 10 has an anti-rotation shape 20 formed by cutting opposing parts on the circumferential surface of the outer part of the housing 19, and a fixed wall 12 opposite to the anti-rotation shape 20. A locking hole 13 is formed, and the locking shape 20 and the locking hole 13 are fitted through a floating gap as shown in the first embodiment.

A floating structure may be formed in this way.

In addition, in the embodiment described above, the one-way clutch 9 has a bearing function, and other clutches may be used as long as it has a bearing function.
