Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deflection device used in a sorter or the like for aligning pages, and more particularly to a device for driving and controlling the deflection device.

Conventionally, in order to reduce the number of monitoring personnel and improve work efficiency, a deflection device that can switch the deflection plate even if an interrupt recording paper or the like is placed on a deflection plate that also serves as a paper discharge tray is being planned.

However, with such a deflection device, there is no problem when only a few sheets of recording paper are collected on the deflection plate, but there is no problem when a large amount of recording paper is collected on the deflection plate. If the drive is operated in spite of this, the drive may be overloaded and damaged.

The present invention proposes a drive/control device for a deflection device that prevents such overload and immediately switches to a desired switching position when a large amount of recording paper is removed from the deflection plate.

Hereinafter, embodiments of a sorter embodying the present invention will be described with reference to the drawings.

In FIGS. 1 to 4, the sorter is equipped with a cart 1 that can be moved to any position, and a vertical support frame 2 is erected on the cart 1. , 4.5, respectively, are installed.

The intake section transport device 3 includes a flat box-shaped base 6 whose base is supported by the support frame 2 .

Two pairs of pulleys 7 and 8 are built inside the base 6, which can adjust the inclination angle by an adjustment mechanism (not shown) according to the height of the paper ejection port B of the copying machine A. Pool 7
, 8, an endless conveyor belt 9, a portion of which is exposed on the upper surface of the base 6, is stretched.

Then, on the base 6 whose tip is lowered diagonally, the base 6
A main paper discharge tray 11 that can be opened is located around a shaft 10 (FIG. 1) that is suspended over the main paper tray 11.

A plurality of driven rollers 12 are supported at the bottom of the main paper discharge tray 11 and are rolled into contact with the upper surface of the conveyor belt 9 .

Therefore, the copy paper from the copying machine A taken into the intake section transport device 3 is conveyed while being held between the transport belt 9 and the driven roller 12.

Further, as shown in FIG. 2, the copy paper discharged from the paper discharge port B is placed at the front end of the intake section conveying device 3 whose leading end faces the paper discharge port B of the copying machine A. Intake section conveyance device 3
Alternatively, a deflecting means 13 for distributing the paper to the main paper discharge tray 11 is provided.

Deflection means 1 capable of tilting about the axis 14 of the base 6 as a fulcrum
3 is an upper plate 15 that constitutes a part of the main paper discharge tray 11;
A lower plate 16 is provided which cooperates with the upper plate 15 to guide the copy paper from the paper outlet B to the intake section conveyance device 3 when the deflection stage 13 is flipped up.

In other words, the deflection means 13 is configured to detect an interrupt copy signal from the copying machine A, a special paper use signal, and/or a "jam" of the sorter.
paper jam) A well-known electromagnetic solenoid or other mechanism energized by an emergency stop signal sets the jam in the position shown in solid line in FIG. discharge.

The copy paper conveyed by the intake section conveyance device 3 is taken up by a vertical distribution section conveyance device 4 connected to the rear end of the intake section conveyance device 3.

That is, the distribution unit conveyance device 4 has a mounting plate 18 that can be opened as shown by the imaginary line in FIG. An endless conveyor belt 21, a portion of which is exposed on the inner surface of the mounting plate 18, is wrapped around the pulleys 19 and 20.

Paper discharge rollers 23 on horizontal shafts 22 (FIG. 3), which are equidistantly spanned over the support frame 2 so as to be vertically adjacent to each other, are rolled onto the surfaces of these conveyor belts 21.

In order to maintain the rolling contact state of these paper ejection rollers 23, auxiliary rollers 24 located inside the conveyor belt 21 are assembled to the mounting plate 18 in correspondence with the paper ejection rollers 23.

These auxiliary rollers 24 are attached to the frame 2 as shown in the third figure.
The shafts 27 are respectively supported by shafts 27 that are stretched between grooves 26 of No. 5.

These shafts 27 are pressed in the direction of the corresponding paper discharge rollers 23 by projections 28 of the frame 25 and tensioned wires 29 alternately hung on each shaft 27.

A paper discharge tray device 5 whose base portion is fixed to the support frame 2 is provided above the main paper discharge tray 11 .

This paper discharge tray device 5 includes a plurality of paper discharge trays 30 whose bases are fixed to the support frame 2 in a state corresponding to each of the paper discharge rollers 23 and which are aligned in the vertical direction.

Therefore, the operator handling the sorter must
1, the user can reach the necessary main paper ejection tray 11 or paper ejection tray 30 by simply standing in front of the main paper ejection tray 11 or paper ejection tray 30.

Gate members 31 (shown in the third figure) are positioned at the entrances of the aforementioned paper discharge trays 30, respectively.

These gate members 31 are fixed to shafts 32 installed on the support frame 2 and can be operated by electromagnetic solenoids 34 coupled to levers 33 provided at the shaft ends of these shafts 32.

Therefore, when one of these electromagnetic solenoids 34 is energized, the tip of the corresponding gate member 31 advances into the copy paper conveyance path constituted by the conveyance belt 21 and paper ejection roller 23, and is conveyed. The copied copy paper is discharged onto the corresponding paper discharge tray 30.

Note that FIG. 4 shows the drive section of the sorter mentioned above, and the timing belt 37, which is hung around the drive pulley 36 of the drive motor 35 installed at the lower part of the support frame 2, is attached to the shaft of the pulley 8 mentioned above and the It is hung on driven pulleys 37A, 38, and 39A fixed to the shaft ends of the horizontal shaft 17, respectively.

FIGS. 5 and 6 show details of the supporting and driving part of the deflecting means 13, which is a characteristic structural part of the present invention, and as described above, the upper plate 15 and the lower plate 16 can move together. is supported on a shaft 14.

The shaft 14, which is rotated to the switching position by a drive device to be described later, has a free end 39a of a fixed biasing spring 39 attached to the lower plate 16 in order to prevent overloading of the drive device.
is pressed against the bottom surface of the deflection means 13, and bears the weight of the deflection means 13.

As will become clear from the description below, in the present invention,
This biasing spring 39 does not necessarily need to be provided at this position, and a storage means corresponding to the biasing spring 39 may be provided in a part of the power transmission system that transmits the switching motion.

FIG. 5 shows details of the drive and control section of the deflection means 13, in which the shaft 14 is linked to the switching position by a spur gear 40 provided at the end of the shaft.

That is, the output shaft pinion 42 of the control motor 41 incorporated in the base 6 is rotated in the direction of the arrow, and this output shaft pinion 42 is meshed with a reduction gear 44 integrated with a cam 43. .

A driven lever 46 biased by a spring 45 is attached to this cam 43.
is pressed into contact with the fan gear 47 at the base of the driven lever 46.
is meshed with the spur gear 40 of the shaft 14.

Therefore, when the control motor 41 is rotated when interrupt copying or the like is finished and it is desired to send copy paper to the sorter, the driven lever 46 is pivoted about its mounting shaft 48 according to the shape of the cam 43. Finally, the sector gear 47 rotates the shaft 14 clockwise.

For this purpose, the shaft 14 transmits this switching movement to the deflection means 13 via the biasing spring 39, which bears the weight of the deflection means 13.

The control motor 41 flips up the deflecting means 13 from the position shown by the solid line to the position shown by the imaginary line in FIG. Although the control motor 41 is stopped by the control motor 41, the circuit is configured to automatically stop the control motor 41 if the micro switch 49 does not sense the deflection means 13 within a predetermined predetermined time period during which the deflection movement is performed.

The signal from this micro switch 49 is also used as a page alignment restart enable signal.

On the other hand, a locking device is provided between the driven lever 46 and the device fixing portion.

That is, this locking device has a latch groove 50 formed at the base of the driven lever 46, and a latch operated by an electromagnetic solenoid 51 at a position of the latch groove 50 corresponding to the flip-up position of the deflection means 13. A claw 52 is exposed.

This electromagnetic solenoid 51 is energized at the scheduled time when the deflection means 13 is to be flipped up, and regardless of whether the deflection means 13 is flipped up, the latch pawl 52 is driven into the latch groove 50 and the shaft 14 is flipped up. Lock it in the appropriate position.

Since the deflection device in the above embodiment has the above-described configuration, when the pages are aligned by a sorter, the deflection means 13 is flipped up to the position shown by the imaginary line in FIG.

Next, when an interrupt copying signal, a "jam" emergency stop signal, or a special paper usage signal is transmitted, the electromagnetic solenoid 51 is first deenergized by these signals, the latch pawl 52 is removed from the latch groove 50, and the driven lever is 46 is dropped by the spring 45, rotating the sector gear 47 and the spur gear 40 counterclockwise, the deflection means 13 is switched to the position shown by the solid line in FIG. 6, and the paper is ejected from the ejection port B of the copying machine A. Preparations are made to collect the copied paper onto the main paper discharge tray 11.

Furthermore, when interrupt copying or special paper copying is completed or the current state is restored, the control motor 41 is rotated again and the deflection means 13 is restored to the position indicated by the imaginary line in FIG. works like this:

If there is not enough copy paper collected on the main paper discharge tray 11,
Since the weight of the copy paper applied to the deflecting means 13 is small, the deflecting means 13 is flipped up by the force of the biasing spring 39, and the page alignment operation is immediately resumed.

On the other hand, even if a large amount of copy paper is collected on the main paper discharge tray 11 and the sorter is switched and left as it is, the control motor 41 continues to drive and the fifth
Although the drive mechanism operates up to the position shown in the figure, due to the heavy weight of the copy paper applied to the deflection stage 13, the biasing spring 39 is bent and the deflection means 13 does not spring up to the expected spring-up position.

Alternatively, for this reason, the control motor 41 is stopped by the command of the micro switch 49 which cannot detect the deflection means 13 even after the scheduled time, and a copy paper removal alarm is issued, and the copy paper on the main paper discharge tray 11 is removed. is encouraged.

Therefore, when the copy paper is removed, the control system up to the shaft 14 has already been switched to the position corresponding to flip-up and is locked by the latch pawl 52, so the energy of the stored biasing spring 39 causes the deflection. The means 13 is automatically flipped up and the micro switch 49 confirms this switching.
The page alignment operation will be restarted immediately.

As is clear from the above explanation, according to the present invention, the drive system is equipped with a power storage means such as a coil spring, so even if excessive recording paper is collected in the deflection stage 13, the drive system No overload will occur.

In the drive/control device of the present invention, when the recording paper on the 1,000-stage deflection stage 13 is removed, the control system, that is, the power transmission system, which has been prepared for switching immediately
3 can be switched by the energy storage means, so there is an effect that the page alignment work etc. can be resumed quickly.

In the above embodiment, the upper plate 15 which bears a part of the weight of the recording paper on the main paper discharge tray 11 was used as an example of the deflecting means, but the upper plate 15 may be used as the main paper discharge tray.
