JPS5948352A - Directing device for paper sheets - Google Patents

Abstract

PURPOSE:To turn a gate round at the desired angle and speed and make the direction of paper sheets securable with certainty, by turning a rotary shaft of the gate directing paper sheets round clockwise or counterclockwise selectively by a driving part via a clutch, while regulating the turning limits with a stopper. CONSTITUTION:When a pulley 24 is rotated by a motor 21, a rotary shaft 32 is rotated as well via gears 26-30, a spring 35 and an arbor 33. And, when a stopper 36 stops a hair of the spring 35, a clutch 31 is disconnected whereby driving force to the rotary shaft 32 gives out. At this time, a gate 12 rotates till the clutch 31 gets disconnected, then copy paper P is directed to a first director passage 13. On the other hand, when the motor 21 is turned round reversely, the rotary shaft 32 also goes into reverse via a gear 30, etc. And the gate 13 remains rotated till a lever 37 is stopped by a stopper 38, causing the copy paper P to be directed to a second director passage 14. According to this method, the gate 12 can be operated at the desired turning angle and speed so that accurate directing takes place.

Description

DETAILED DESCRIPTION OF THE INVENTION Q: For example, a 14'. Do 1.

[Technical background of the invention and its problems]

For example, in a fixed bin type sorter, it is necessary to switch the paper sheet conveyance direction between sorting bins and non-sorting bins.

Therefore, conventionally, a sheet sorting device as shown in FIG. 1 has been used.

That is, in the figure, Jij: (b) is a freely movable gate, and this rotating shaft 2 (- is connected to a solenoid 30, 11 + rod 4, and a spring 5. Therefore, when the solenoid 3 is energized, tL , the gate 1 rotates in the input direction to sort the fine leaves in the first direction, and when the solenoid 3 is demagnetized, the gate 1
However, in this device, the rotation angle I of the gate 1 corresponds to the operation of the solenoid 3 - the stroke of the rod 4. Furthermore, if the solenoid 3 (-) is used to drive the gate 1, the gate 1 cannot be operated within the desired speed range, and distribution cannot be performed reliably.

[Purpose of the invention]

The present invention has been made based on the above-mentioned situation C2, and its purpose is to enable the gate to operate at a desired rotation angle and rotation speed, thereby ensuring reliable distribution. Our objective is to provide a paper sheet (hQ separation device).

[Summary of the invention]

The present invention provides a rotatable gate for sorting paper sheets, and a pivot shaft of this gate that can be rotated in the forward direction or in the reverse direction to make an f-fold.
a clutch that connects and disconnects the tdZ 171+ force from the sum lII of the drive g[(and and tdZ 171+) to the cooperating shaft of the gate;
The present invention is characterized by comprising a stopper for regulating the same range of the gate.

[Example of invention]

Hereinafter, one embodiment 1411 of the present invention will be described with reference to FIGS. 2 to 5. FIG. 2 does not show a sorter using the paper sheet 417 sorter according to the present invention C', and I) in the figure is a receiving section for receiving paper sheets, such as copy paper P. As shown in FIG.
It is designed so that it can be selectively distributed to the distribution paths 13 and 14. Then, first take-in rollers J, 5, 15 are arranged in the first sorting path 13, and the sorted copy paper P is picked up. The second sorting path 14 includes a conveyor belt 17 that conveys the sorted copy paper P downward, and a conveyor belt 17 that moves up and down along this conveyor belt 17. a pawl 19 that moves and selectively deflects the conveyed copy paper P to a plurality of sorting bins 18 disposed along the conveying belt 17 (2); A sorting bin 18...second take-in rollers 20, 20 are arranged to take in the deflected copy paper P.Furthermore, the first take-in rollers 15, 15, the conveyor belt 17, and the gate are arranged. J 2 YJ: C2 is driven by the motor 21C, which is a single drive unit capable of forward and reverse rotation.

That is, when the motor 2] is rotated in the normal direction by the first one-way clutch 22, the first intake roller
It is driven twice, and it seems to be driven when reversing (the two is attached).

The conveyor belt 17 is driven by the second one-way clutch 23 when the motor 21 rotates in the reverse direction, and is not driven during the forward rotation. When the rotation is forward, it is distributed to the first distribution path 13, and when it is reversed, it is distributed to the second distribution path 14. In other words, 24 is driven by the motor 21 via a belt (not shown). The driving force of this pulley 24 is transmitted to the first gear 26 via a coupling plate 25.

A second gear 27 meshes with this first gear 26, and this second tooth piece 27 is fitted into a collar 28 (which is inserted into the collar 28). The fourth gear 30 meshes with the third gear 29+-, and the driving force of the @4 tooth 30 is transmitted through the clutch 3. Gate 12 above
It is C-shaped so that it is transmitted to the co-moving shaft 92. In other words, an arbor 33 is fixed to the rotating shaft 32 by a pin 14, and the arbor 33 (2) is fixed so that the driving force of the fourth gear 30 is transmitted by the tightening force of the spring 35 (= previously In addition, a first stopper 36 for connecting and disconnecting the clutch 31, and a second stopper 36 for restricting the rotation of a lever 37 fixed to the rotation shaft 32 when the clutch 31 is disconnected.
The stopper 38 is attached to the frame 39 (-), so that the rotation range of the gate 12 is restricted. Also, the first and second stoppers, 76° 38, are movable. ζ2 is set so that the rql !ill range of the gate 12 can be adjusted.

However, when the motor 2 rotates in the normal direction and the pulley 24 rotates, this KIJ lh force is applied to the first, second, third and fourth gears 26, 27, 29, ,'lO, Spring 35, arbor, 73 Ill+'i 1.
Rotating axis 321-den! Commanded, 1 "Jth IhI! 1ll
I32 is rotated.

At that point, when the first stopper 36 closes the barb of the spring 35, the clutch 31 is disconnected and the driving force to the rotating shaft 32 is cut off. At this time, the gate 12 rotates #11 until the clutch 31 is disconnected, and in this state, the copy A11x
P to the first distribution path reservoir.

Next (2) When the motor 21 reverses, the driving force is transmitted in the same way as above and the fourth gear 3o is rotated in the opposite direction. The rotation shaft 32 rotates in the opposite direction due to the sliding or friction that exists in the rotation axis.At this time, if the lever 37 is biased toward the second stopper 38 by a spring or the like, rotation force in the opposite direction can be obtained. And gate 12tfl
The lever 37 rotates until it stops at the second stopper 38,
In this state, the copy paper P is distributed to the second distribution path 14.

According to the above configuration, the clutch 31 and the stopper, ? 6

(1) Furthermore, since the drive speed [W] of the rotating shaft 32 by the motor 21 can be reduced or increased, the gate 12 can be operated at a desired rotational speed, for example, quietly. , reliable distribution can be performed.

〔Effect of the invention〕

As explained above, according to the present invention, there is provided a rotary gate for sorting paper sheets, a drive portion for selectively rotating the rotary shaft of the gate in the forward or reverse direction, and Since it is equipped with a clutch that connects and disconnects the driving force from the drive unit to the rotating shaft of the gate, and a stopper that protects and controls the rotation range of the gate, the gate can be rotated to a desired rotation angle of 18 hexagrams. It can be worked at a rotational speed, and has excellent effects such as reliable digging.
