Abstract

PURPOSE:To make branching conveyance possible in other two directions by switching one branching gate in combination of two kinds of drive source, even if paper sheets are conveyed from any direction out of the three conveyance passages crossing together at one point. CONSTITUTION:A branching gate 1 which is provided at an intersection point of three conveyance passages (a), (b), (c), crossing together at one point is connected to a gear 5 and made to swing by a drive source 2 so as to branch the conveyance passages. Rotation angle of the drive source 2 is regulated by the stopper of a pin 8 and a hook 9. Ordinarily, conveyance from the passage (c) to the passage (a) is possible and when only the drive source 2 is started, conveyance from the passage (c) to the passage (b) is possible. When a drive source 2 is started after starting of an axis 3, rotational angle regulation by the hook 10 is released so that rotation angle of the drive source 2 increase and conveyance from the passage (a) to the passage (b) becomes possible.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet conveying / branching mechanism, and more particularly to a paper sheet conveying / branching mechanism that sorts and conveys paper sheets by swinging a branch gate.

[0002]

2. Description of the Related Art A conventional paper sheet conveying / branching mechanism is, as shown in FIG. 3, provided with a swingable branching gate 1 provided in the vicinity of an intersection of a conveying path which intersects at one point from three directions, and when this is required. It has a drive source 2 for rocking.

Next, the operation of this conventional example will be described.
FIG. 3 exemplifies a case where, out of the three-direction transport paths, only the paper sheets transported from the transport path c are distributed to the transport path a or the transport path b.

When the state shown in FIG. 3 (E) is the initial position of the branch gate 1, all the paper sheets sent from the transport path c are transported to the transport path a. From this state, when trying to send the paper sheets to the conveyance path b, the shaft 3 fixing the branch gate 1 is rotated by the drive source 2 and the branch gate 1 is moved at the position shown in FIG. 3 (C). Stop.

By swinging the branch gate 1 in this way,
(D), by stopping at two places in Figure 3 (E),
The paper sheets sent from the transport path c are sorted and transported in the two directions of the transport paths a and b.

[0006]

In the above-described conventional paper sheet conveying / branching mechanism, in the conveying path intersecting at one point from three directions, the swing of the branch gate provided at one position near the intersection is reduced by one. By stopping at two positions by one driving source, only the paper sheets from a specific direction among the three-direction transport paths are distributed to the other two directions. For this reason,
With a branch gate provided in one place, when the paper sheets are conveyed separately from all directions, each paper sheet cannot be sorted into the other two directions. To enable this, There is a problem that it is necessary to install three branch gates near the intersection of the transport path.

SUMMARY OF THE INVENTION A paper sheet conveying / branching mechanism according to the present invention is provided with a swingable branch gate provided at one location near an intersection of a conveying path that intersects at one point from three directions, and this branch gate. A plurality of rotation stop mechanisms for stopping the swing of the branch gate at a predetermined position, and a second drive means for retracting a part of the rotation stop mechanism. It is characterized by

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIGS. 1A and 1B are a structural view and a sectional view showing an embodiment of the present invention. Transport path a,
A shaft 3 is supported at the intersection of b and c so as to be freely rotatable. A gear 4 is fixed to the tip of the shaft 3, and a plurality of branch gates 1 are fixed to the portions through which the paper sheets pass. The drive source 2 is a rotary solenoid that rotates forward and backward by switching the polarity of the current. A gear 5 is fixed to the tip of the drive shaft and meshes with the gear 4 at the tip of the shaft 3. As a result, the rotational movement of the drive source 2 is transmitted to the shaft 3 and the branch gate 1 can be rotated. Also,
A pin 8 is press-fitted and fixed on the side surface of the gear 5, and a stopper 7 is installed so that the pin 8 stops at a predetermined position when the gear 5 rotates forward and backward. This allows the branch gate 1 to stop swinging at two predetermined positions when the drive source 2 rotates forward and backward. Further, a freely rotatable hook 9 urged by a spring 10 is installed so that the tip of the hook 9 can stop the rotation of the pin 8 on the way,
The lower end of the hook 9 is attached to another drive source 6. A solenoid is used as the drive source 6, and the hook 9 is attached to the pin 8 at the time of activation.
Evacuate from the rotation orbit.

Next, the operation of this embodiment will be described.
2 (A), FIG. 2 (B), FIG. 2 (C), FIG. 2 (D), and FIG. 2 (E) are diagrams showing the operation of the embodiment shown in FIG.
When the state shown in FIG. 2A is set to the initial position of the branch gate 1, the paper sheets can pass between the transport paths a and c. When the paper sheets are conveyed from the conveyance path a to the conveyance path b from this state, as shown in FIG. 2C, the gear 5 is rotated in the r direction by the activation of the drive source 2 so that the branch gate 1 Is rotated in the s direction so that the state shown in FIG. After this operation, the paper sheets can pass between the conveyance paths a and b, and by switching the current polarity of the drive source 2, the paper sheets sent from the conveyance path a are conveyed to the conveyance path b or the conveyance path. It can be sorted and conveyed in the c direction.

When the paper sheet is conveyed from the conveyance path c to the conveyance path b from the state shown in FIG. 2A, first, the drive source 6 is activated and the hook 9 as shown in FIG. 2D. And pin 8
Evacuate from the rotation orbit. Next, when the drive source 2 is activated to rotate the gear 5 in the r direction, the branch gate 1 is rotated in the s direction, and the state shown in FIG. After this operation, the paper sheets can pass between the conveyance paths c and b, and by switching the current polarity of the drive source 2, the paper sheets sent from the conveyance path c are conveyed. It can be sorted and transported in the direction of a or the transport path b. Further, by combining the operations shown in FIG. 2B and FIG. 2C described above, the paper sheet sent from the transport path b may be sorted and transported in the transport path a or the transport path c direction. It will be possible.

As described above, according to the present invention, in a conveying path that intersects at one point in three directions, a swingable swinging branch gate provided at one place near the intersection and this branch gate are provided. A drive source for swinging when necessary, a plurality of rotation stopping mechanisms for stopping the swing of the branch gate at a predetermined position, and another drive source for retracting a part of the rotation stopping mechanism when needed Therefore, the swing of the branch gate 1 can be stopped at three positions, and no matter which direction the paper is conveyed from among the three-direction conveyance paths,
There is an effect that it can be distributed to each of the other two directions.
