Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a four-way transport switching device for paper sheets. That is, the paper sheets sent out by the conveyor belt are appropriately switched in four desired directions by three forks to ensure reliable and good delivery guidance, and the three forks are rotated by the related operation of two solenoids. They can be easily switched by simply moving them, and they can be made compact without taking up space at the end of the conveyor belt, allowing the machine to be made as small as possible, making switching control simpler and more compact. The purpose is to provide the following information so that the following can be achieved and implemented in a suitable manner.

Next, the embodiment shown in the drawings will be described.

The paper sheet processing machine is configured to be able to switch and transport paper sheets in four directions from the terminal ends of both conveyor belts B1 and B2, which grip and convey paper sheets.

Double conveyor belt B that conveys paper sheets in the direction of arrow A
The terminal ends of B1 and B2 are wrapped around rolls 4 and 5, respectively, and the roll 6, which is pivoted below the lower roll 5, has a conveyor belt B3 attached to the conveyor belt B2.
The conveyor belts B2 and B3 are arranged so as to extend in the fourth direction C4.

On the extended side of the conveyor belt B1, there is a first belt whose both side surfaces 1a and 1b serve as conveyance guide surfaces for paper sheets.
A fork F1 is mounted on a shaft so that it can rotate around a shaft 7, and a second fork F whose both side surfaces 2a and 2b serve as conveyance guide surfaces is installed on the side that is an extension of the conveyor belt B2.
2 is mounted on an axis so that it can rotate around a shaft 8, and on the side where both conveyor belts B2 and B3 extend, there are both side surfaces 3a, one side surface 3b of which is greatly curved.
A third fork F3 having a diameter 3b is mounted on an axis so as to be rotatable around a shaft 9, and a side surface 1a of the first fork F1 is
Both rolls 11a and 11b are provided on the tip side of the guide rail 10 extending from the side of the roll 4 correspondingly.
so that a first direction C1 is formed through the gap;
Side surface 1b of first fork F1 and second fork F2
Both rolls 12a,
12b so that a second direction C2 is formed between them, and both rolls 1 are provided on the extended side between the side surface 2b of the second fork F2 and the side surface 3a of the third fork F3.
A third direction C3 is formed through between 3a and 13b, and the side surface 3b of the third fork F3
The fourth direction C4 is formed on the extension side between the roller 5 and the outer peripheral side of the roll 5.

On the outside of each fork, both solenoids S1 and S2, which have retractable rods 14 and 15 that protrude when off and suck when on, are fixed in a cross direction, and one end of an arm 16 with the shaft 8 inserted in the middle. and the tip of the retractable rod 14 are connected via a pin 17, a pin 19 is fixed at the tip of the arm 18 into which the shaft 7 is inserted, and an arm 20 into which the shaft 9 is inserted in the middle. One end and the tip of the retractable rod 15 are connected via a pin 21. In addition, longitudinal holes 21 and 22 are formed in the middle and one end of the interlocking rod A made of a long plate, and a horizontal hole 23 is formed in the other end.
9 is fitted into the horizontal hole 23, the pin 24 fixed to the other end of the arm 16 is fitted into the vertical hole 21, and the pin 25 fixed to the other end of the arm 20 is fitted into the vertical hole 22. , one end of the tension spring 26 is engaged with the pin 19, and the other end of the tension spring 26 is engaged with the other fixing pin 27.

Therefore, as shown in Fig. 1, the solenoid S
1 is turned on and solenoid S2 is turned off, the arm 18 rotates counterclockwise in the figure due to the tension of the tension spring 26, and the interlocking rod A is pulled downward in the figure, as shown in FIG. As shown, the first fork F1 and the second fork F2 rotate counterclockwise in the figure, and the paper sheets conveyed between the conveyor belts B1 and B2 are transferred to the first fork F1 as shown by arrow A. It is guided by the side surface 1a of , and is carried out between the guide rail 10 in the first direction C1.

Also, when the solenoid S1 is turned on and the solenoid S2 is turned on, the tension spring 26
The first fork F1 is rotated clockwise while the interlocking rod A is raised as shown in the figure, and the second fork F2 remains rotated counterclockwise until it reaches the state shown in Figure 3, where the arrow As shown in A, the conveyed paper sheets are conveyed between the side surface 1b of the first fork F1 and the side surface 2a of the second fork F2, and are carried out in the second direction C2.

Further, when the solenoid S1 is turned off and the solenoid S2 is turned on, the interlocking rod A is raised in the figure, and as shown in FIG. 4, the first fork F1 and the second fork F2 move clockwise in the figure. The third fork F3 rotates counterclockwise in the figure, and as shown by arrow A, the paper sheets being conveyed are the side 2b of the second fork F2 and the side 3 of the third fork F3.
a and then transported in the third direction C3.

Furthermore, when the solenoid S1 is turned off and the solenoid S2 is also turned off, the interlocking rod A is raised in the figure, and the first fork F1 and the second fork
Fork F3 rotates clockwise in the figure, the third fork F3 also rotates clockwise in the figure, and the fifth fork F3 rotates clockwise in the figure.
As shown in the figure, the paper sheets being conveyed as shown by arrow A are placed between the side surface 2b of the second fork F2 and the side surface 2b of the second fork F2.
They are sequentially guided by the side surface 3b of the fork F3 and transported in the fourth direction C4.

In this way, the present invention arranges the first fork, the second fork, and the third fork, each of which has both sides serving as conveyance guide surfaces for paper sheets, close to the terminal end of the conveyance belt, and Each fork is rotatably installed so that ejection can be guided in four directions between the corresponding surfaces of the fork and from one side of the forks on both ends, and each fork is interlocked and linked to two solenoids and an interlocking rod between them. By turning on and off both solenoids, each fork is rotated in relation to each other, allowing switching guidance in the four directions described above.For example, in a paper sheet processing machine, three sheets of paper are sent out by the conveyor belt. The forks can be switched appropriately in each of the four desired directions to reliably deliver the feed, and the switching can be done well simply by rotating the three forks through the related operation of the two solenoids and the interlocking rod. It has the advantage that the installation space is small, the aircraft can be made compact, and the switching control can be simplified and compacted, making it suitable for implementation.
