Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a paper sheet that is fed out one by one, such as a banknote, and is used to count the paper sheets and to determine the denomination, authenticity, etc. In a leaf processing device, if the sheets that are fed out one by one come out overlapping or folded, the machine will automatically stop feeding, but there will be a problem between the feeding roller and the regulation block. The present invention relates to a device that is capable of easily removing and discarding paper sheets that have become jammed.

(Prior art) Conventionally, in this type of device, a large number of stacked paper sheets are fed out one by one by a push-out roller, and the fed-out paper sheets are fed out between the feed-out roller and a regulation block. Then, it is determined by this regulation block or other detection means whether the sheets are being fed correctly one by one. As a means of adjusting the gap between the feeding roller and the regulating block, it has been shown that a paper thickness adjustment screw is used as shown in Japanese Patent Publication No. 59-41892, and the rotation and friction for paper feeding are used. Japanese Utility Model Publication No. 51-9921, which is a device for adjusting the slit between two rollers, is also known as a device for adjusting the thickness between two rollers to the thickness of one sheet of paper.

(Problems to be Solved by the Invention) In the above conventional example, when a paper sheet becomes jammed for some reason between the strictly regulated feeding roller and the friction member facing it, the gap is adjusted and regulated. There was no way to remove the jammed paper without changing the paper.

(Means for Solving the Problem) In the present invention, for example, when two sheets are fed out in a stack, this regulation block or other detection means senses this and automatically stops feeding out the paper sheets. It's getting old. Therefore, since a strictly finely regulated gap (the amount of passage of one paper sheet) is maintained between the regulation block and the delivery roller, it is difficult to easily remove the paper sheets that are stuck there. For example, it is necessary to remove the bearing portion of the feeding roller or to remove the regulating block, which wastes time, and especially when the regulating block is removed, there is a strict gap again, making fine adjustment difficult.

The present invention is an easy-to-operate and highly accurate device that allows the regulating block to be separated from the feeding roller, accurately positioned, and returned to its original position with a single touch. That is, an adjustment dial for regulating the gap is provided on an adjustment plate connected to the regulation block, and by actuating this dial with an operating lever, the regulation block is moved further away from the feeding roller.

(Function) When the operation lever is operated, the adjustment plate is operated around the shaft via the pin, widening the gap between the feeding roller and the regulation block and removing paper jams, and since the adjustment dial is not operated in any way, it can be operated. When the lever is returned to its original position, the gap can be maintained accurately again.

(Example) Next, a detailed explanation will be given based on an example of the apparatus of the present invention shown in the drawings.

The embodiment shown in the figure is a banknote processing machine, in which a box 2 in which a large number of banknotes 1 are stacked is placed inside a body 3 in which a box 2 is removably attached, and an eccentric push-out roller 4 is placed in contact with the lowest banknote of the banknotes 1. It has a feed-out roller 5 from which the pushed-out banknotes are fed out, and a regulation block 6 positioned at a predetermined gap (normally a gap for one banknote) from the feed-out roller 5. The regulating block 6 is fixed to an adjusting plate 7, and this adjusting plate is pivotally connected to the main body 3 by a shaft 8 at a position below the regulating block 6.

Above the adjustment plate 7, a pin 9 is planted, and in contact with this, the operating lever 10 is attached to the fuselage 3 at a fulcrum 11.
An adjustment screw 12 is screwed into the adjustment screw 12, and an adjustment dial 13 with a scale is fixed to the adjustment screw 12. However, the spring 15 is connected to the regulating block 6 and the fuselage 3 so that the tip of the adjusting screw 12 can come into contact with the fixed adjusting block 14.
is established between.

Although not directly related to the present invention, a plurality of feeding rollers 5 are provided with gaps around the rotation shaft 16, and a plurality of resistance rollers 17 are positioned in the spacing. It lightly contacts the opposite side of the banknote being fed by the banknote, providing appropriate resistance to the banknote. The lever resistance roller 17 is therefore pivoted on a bracket 18 together with a ratchet wheel 17'. The bracket 18 is connected to the regulation block 6 by the shaft 19.
The bracket 18, ie, the resistance roller 17, etc., is supported through the axis 19, and is adapted to adjust the appropriate resistance to the banknote by means of an adjustment screw 20 screwed into the adjustment plate 7. Furthermore, a ratchet pawl 21 pivotally connected to the adjustment block 14 is engaged with the ratchet wheel 17', so as to rotate the ratchet wheel 17' clockwise but not counterclockwise in FIG. It is provided. Note that 22 is a group of feed rollers, and the banknotes that have passed through the regulation block 6 are fed through the banknote passage 24 by the group of feed rollers 22 and the feed belt 23, during which time the number of banknotes is counted, the denomination is determined, and whether the banknotes are genuine or counterfeit. After being subjected to processing such as identification, etc., it is sent onto the stacking table 25.

When the two banknotes 1 in the box 2 are pushed out in an overlapping manner as the extrusion roller 4 rotates, they enter the adjusted gap between the feed roller 5 and the regulation block 6, so the regulation block 6 moves or Furthermore, if a banknote 1 becomes jammed within the interval, this is detected mechanically or electrically and the machine stops. Then, when the operating lever 10 is operated in the direction of the arrow in FIG. 2, the regulating block 6 together with the adjusting plate 7 is moved clockwise in FIG. and move. (See FIG. 3) Therefore, the gap between the regulating block 6 and the feeding roller 5 is wide, allowing jammed banknotes to be taken out in the opposite direction to the feeding direction.

At this time, the resistance roller 17 is connected to the ratchet 1.
Since it is rotated in the movable direction of 7', there is no problem in taking it out. However, after taking it out, the operation lever 10
When the operation is released, the regulation block 6 rotates counterclockwise around the shaft 8 due to the bias of the spring 15.
The amount of rotation is regulated by the adjustment dial 13.The tip of the adjustment screw 12 comes into contact with the fixed adjustment block 14 and is accurately returned to its original position, so there is no gap between the feeding roller 5 and the regulation block 6. never changes.

(Effects of the Invention) According to the present invention, the regulating block can be easily opened and paper jams can be removed with a single operation, and when the regulating block is returned to its original position after clearing, the position can be accurately maintained, making continuous work possible. This makes it possible to improve efficiency.
