Abstract

PURPOSE:To enable a sorter to be easily fixed to a copying machine different in conveyance speed, and to enhance versatility, by using a pulse motor for a drive source, and by conveying a copy discharged from a copying machine at a speed adjusted with the frequency of pulses. CONSTITUTION:A conveyor belt 10 for transporting a copy sheet 4 in a sorter 1 is driven with a pulse motor 13. Therefore, the sorter 1 can be easily mounted on various kinds of copiers 2 even different in conveyance speed due to difference in the copiers 2, only by adjusting pulse frequency to be applied to the motor 13, to a pulse frequency corresponding to its conveyance speed. At that time, terminals for selecting pulse frequency in accordance with the conveyance speeds of various kinds of copiers are provided in a controlling circuit, thus permitting a sorter 1 to be easily fixed to a copier 2 by designating its terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorter, and more particularly to a sorter suitable for adjusting the conveyance speed during copy delivery in accordance with the conveyance speed on the copying machine side.

Generally, in a sorter, in order to stably feed the copies ejected from the copying machine into the bin, while the copies are passing from the copying machine to the sorter, the conveyance speed on the sorter side is set to be the same as that on the copying machine side, so that the copies are transferred from the copying machine to the sorter. I am trying to increase the speed when I exit the plane.

In this case, if the conveyance speed of the copying machine is different, the conveyance speed of the sorter side must be adjusted accordingly, but in conventional sorters, an analog motor such as an induction motor is used as the drive source. Since the conveyance speed was increased via a clutch, it was not easy to adjust it.

An object of the present invention is to provide a highly versatile sorter that uses a pulse motor as a drive source and can be easily adapted to copiers with different conveyance speeds due to its low speed.

The present invention will be explained below with reference to embodiments shown in the drawings.

At 11.1 in the case of heather M11, in order to conduct a con-straight VC on the sorter 1, the conveyance path height from the JJI coarse grain to the bin 7 on the right side is <9, so copy sheet 4 is moved in the lower direction. Put it in the bottle 1. The tip of the copy sheet 4 does not reach the bin entrance before the rear fly of the copy sheet 4 comes out of the dokusha 2, and it is located at Z. Therefore, in this example, 4)
i On the paper - ' I - - Before 6 is turned off, that is, ■, corner, :r Kisuno! Before the non-fJ'((+-i) signal input to the fl/control circuit 21 via the controller 20 reaches 0N-J, the counter A determines whether the calculated pulse number NK is 1 or less. [I try to do it.]

Based on this judgment result, the counter A is set to the specified number N.
, it means that the leading edge of the copy sheet 4 has reached the pin sensor 18, so step STI
Check whether the pin sensor J8 is ON or not, and determine if it is ON with force or if it jams during the process. Pin sensor 18 is ON [, te) 1. Then, check whether the paper ejection sensor 6 is OFF.

On the other hand, input copy sheet 4 into the bin in the direction of the earthen step.

If so, the judgment in step ST1] e1 result is No, and first turn off the paper ejection sensor 6. I'm going to sleep.

At this time, if the paper ejection sensor 6 is OFF, then B.

Increase the pulse frequency applied to the pulse motor 13 and increase the speed of the conveyor bell (10'i4 to 5). At the same time counter B
Activate it and calculate its Noyals PkWl number.

This counter B calculates the number of pulses Pz at 1 from the copy sheet 40 trailing edge 1 paper sensor 6 to the entrance sensor 17.
k is counted, and in step ST2, the result is 1 IL, N
If it is o, return to STI again and repeat the process (9) above.

If the judgment result at Stella f Sr1 is YES, then move on to Fig. 5 (1)) and check the state of the entrance sensor 17. If the entrance sensor 17 is not OFF, there is a jam. (It is determined that it is -. On the other hand, the entrance sensor -
17 is 0FIi', then a counter C is created and the pulses P from the R pulse generator 19 are counted.

Thereafter, it is determined whether the IQ counter A has reached the specified number of pulses N, and if it has reached the specified number of pulses N, the state of the pin sensor 18 is checked. As a result, copy sheet 1
It is determined whether the tip of -4 has reached the bottle entrance, and if it has not, it is determined that there is a jam. Next, it is determined whether the counter C has reached the specified number of pulses N, and the specified number of pulses NK is determined.
If this happens, check the bin sensor 18.
It is determined whether or not the rear end of the copy sheet 4 reaches the bottle number 1. If the rear end of the copy sheet 4 does not reach the bottle number 1, the bottle sensor 18 will not turn off and it is therefore determined that the shirt is on.
A jam is detected at point 1, where the jam enters the bin after reaching the bin entrance.

(10) If the copy sheet 4 does not jam during the process and enters the currently selected bin 7, the current bin number n
After outputting to the copying machine 2, the process moves to FIG. 5(c), the solenoid 15 is turned off, and the pulse frequency is returned to the initial low frequency again. At this time, copy machine 2 to 5 I1
It is checked whether the copy end signal d is input to the control device 21 via the 0 expander 20, and if copying is in progress, that is, if the judgment result at Stella: 7' Sr1 is NO, the mode at this time is the sort mode. In sort mode, the content n of register A is incremented by 1, while in collate mode, it is set to -1, 1, and then
After returning to the procedure in Figure 4, move on to the procedure in Figure 5 again.
Repeat this. On the other hand, if the determination result in step 5ST3 is YES, the motor 13 is turned off.

Thereafter, the content n of register A is set to 1 if the mode is sort, and the content n of register A is incremented by 1 if the mode is collate, and the process returns to the procedure shown in FIG.

In this way, in the sort mode, one copy sheet 4 is sequentially stocked one by one, starting from the top of the bin, and the copy end signal d causes the copy sheets 4 to be stocked one by one, starting from the top of the bin.
control to return to .

In addition, in the collate mode, the copy sheets are sequentially scanned from the top of the bin until the copy end signal d is input, and when the copy end signal d is input, the copy sheet is moved to the next bin.
Controls to return to the top row when it is no longer in collate mode.

On the other hand, jam detection during this time is by counters A and B.

C is installed to monitor the conditions between the entrance sensor 17 and the bin sensor 18, between the bin sensor 18 and the trench where the bin 7 is stocked, and between the trailing edge of the copy sheet from the discharge sensor 6 to the entrance sensor 17. As a result, the control circuit 21 can quickly detect any jamming of the copy sheets 4 in the sorter 1.

As a result, if the control circuit 21 detects a jam, it moves to the procedure shown in FIG. Ru. After that, remove the jam and press the reset button (not shown) to return to the procedure shown in FIG. 4 again.

Next, when the interrupt mode signal C is input from the copying machine 2 to the control circuit 21 via the I10 expander 20, the procedure shown in FIG. 6 is executed. That is, in the case of the interrupt mode, the copy sheet 4 ejected from the copying machine 2 is put into the bottom bin 7-n, so the CPU stores the number of pulses N=P, +-P4 in the ROM. Take 9 out, R
Set it in AM. Next, when the leading edge of the copy sheet 4 passes the entrance sensor 17, the entrance sensor 1
7 is turned on, the armature motor 13 is driven, and after the solenoid corresponding to the lowermost bin 7-n is turned on, the counter A is operated.

Next, when the counter A reaches N, the bin sensor 18
By checking whether the copy sheet 4 is ON, it is determined whether the leading edge of the copy sheet 4 has safely reached the bin sensor 18 from the entrance sensor 17, and a jam is detected during that time.

(13) After that, the paper ejection sensor 6 is turned OFF, that is, I10 EXNO♀
Turn on the paper ejection signal e inputted through the printer 20 (check 5, if the copy sheet 4 passes through the copying machine 2, increase the zf pulse frequency, keep the conveyor belt 10 running, and then turn on the counter B. .

Next, by checking whether the entrance sensor 17 is turned off when the value of the counter B reaches P3, a jam is detected when the trailing edge of the copy sheet 4 reaches the entrance sensor 17 from the paper discharge sensor 6.

If no jam is detected, activate counter C.
Bin sensor 1 when the value of this counter C reaches N
8 is OFF, it is checked whether the copy sheet 4 has reached the bin sensor 18 from the inlet sensor 17 until the copy sheet 4 enters the bottom bin 7-n from the bin sensor 18. Detect jams.

In this way, the copy sheet 1 ejected from the copying machine 2
If a jam is detected during the process of putting 4 in the lowermost bin 7-11, the jam processing shown in FIG. 8 is performed as described above. - If no flange jam is detected, (14) Return to the procedure in Figure 4 again, and as long as 1 interrupt mode signal 0 is input, move from the procedure in Figure 4 to the procedure in Figure 6, and perform the same process as above. , the copy sheets 4 ejected from the copying machine 2 are stocked one after another in the lower bin 7-n. On the other hand, if the sorter 1 is not designated with a mode from copy 1 or 2, it becomes the normal mode and the control The circuit 21 executes the operation 1111''t=p shown in FIG. Number of loops N = Po ten P, taken out from all ROM, RAM
Set inside. Well, the selection operation of the solenoid 15 is not performed, and when the entrance sensor 17 is turned on, the pulse motor 1
3'(rONL,, create counter Ah+L, then,
Turning off the paper ejection sensor 6, that is, turning off the I10 output sensor 20
It is checked whether the paper ejection signal θ inputted via is ON.

As a result, if the paper discharge signal e turns ON, the flat pulse frequency is increased and the conveyor belt 10'? Il- After speeding up, counter B is activated.

Next, in the same way as in the interrupt mode described above, the entrance sensor 17 is activated when the value of this counter B reaches P3.
OFF' (By checking i7, all jam detection is performed.

If no jam is detected, after activating counter C, the bin sensor 1 is activated when the value of counter A reaches N.
8 is turned on, a jam from the inlet sensor 17 to the bottle sensor 18 is detected. Next, the value of the counter C reaches N and the Tatoki bottle sensor 18 is turned off.
By checking this, a jam is detected from the time when the copy sheet 4 enters the uppermost bin 7-1 from the bin sensor 18.

Historically, when such jam detection is performed and a jam is detected during the process, the jam processing shown in Fig. 8 is carried out, and if no jam is detected, the processes from Fig. 4 to Fig. 7 are repeated. All the copy sheets 4 discharged from the copying machine 2 are stored in the uppermost bin 7-1.

The sorter 1 of this embodiment includes the entrance sensor 17 that detects the presence or absence of the copy sheet 4 in the copy conveyance path as described above;
While a bin sensor 18 is provided, a pulse generator 19 is provided which generates 4 pulses (copy conveyance synchronization), and this pulse generator 19 generates 4 pulses when the leading or trailing edge of the copy sheet 4 is connected to the entrance sensor 17.
Counting starts at the timing when the entire copy sheet 4 passes through, and also at the timing when the rear end of the copy sheet 4 is ejected from the copying machine 2, and these counted values are sent to the entrance sensor 17 determined in advance.
, the number of pulses between the bin sensor 18 or the number of pulses between the copying machine 2 and the entrance sensor 17 has been reached. A timer is sometimes used to detect jams.

Therefore, jams can be detected reliably and quickly without being affected by the conveyance speed of a copying machine installed like a conventional copying machine. At the same time, by simply adjusting the transport speed when making 90 copies to that of the copying machine, it becomes possible to easily print copies on different types of copying machines.

In addition, as shown in Figure 3, the copy conveyance path (17
)On the road, only the number of pulses Po to P4 during the basic distance is memorized, and the number of pulses at a predetermined bin entrance size is determined from the entrance sensor 17 by a total of 9, so the memory capacity can be reduced. can.

Furthermore, in this actual M11 example, the conveyor belt 10'ff-pulse motor 13 is driven by L, so the sorter 1
Even if the copying machine transport speed differs due to the different models of the ladle copying machine 2 to which the ladle motor 13 is attached,
By simply adjusting the pulse frequency applied to the pulse frequency (f number) corresponding to the conveyance speed, sorter 1 can be
It can be easily installed on the J7 camera.

In this case, the pulse frequency adjustment is output to the pulse motor 13 at the time of copy delivery)? The control circuit 21 is provided with a terminal for selecting the Lunu wave number corresponding to each 81 copying machine transport speed, and when the sorter 1 is attached to the copying machine 2,
This can be easily done by setting the terminal to '411'. Alternatively, the conveyance elongation can be input from the copying machine 2 side to the control circuit 21 of the sorter 1 using a BCD code.
From the pulse total control circuit 21 of the frequency corresponding to the frequency (1Q'
ll ・Gurusmoke 131C may be output.

Furthermore, the pulse signal per distance η' is extracted from the conveyance roller of the copying machine 2, and the frequency is calculated by kneading.
The pulse frequency can be adjusted arbitrarily, such as by applying .9 Lus (i7/'' Lus) of that frequency to the motor 13.

Further, in this embodiment, the conveyor belt 10 is moved by the pulse motor 1.
3, however, similar effects can be obtained by using a surf g motor provided with a return circuit.

As described above, since the present invention uses the 111i motor as the drive source for copy conveyance in the sorter, it can easily be used for copying machines of different models without requiring complicated adjustments. A sorter with excellent versatility is obtained.
