JPS61291350A - Handling method for unuseable transfer paper - Google Patents

Abstract

PURPOSE:To discharge the unuseable transfer paper at the time of jam happening outside a device as many as possible and thereby make jam handling ever so easy, by installing a conveying route selector device which retract the transfer paper in the point midway in its handling at the upstream side of operation of the transfer handling device. CONSTITUTION:A conveying route selector claw 5 is being installed in a conveying route A and situated in a normal position(a). When a jam occurs in a recording device 2 and paper feeding has been already started out of a paper feeder 1, this claw 5 is selected to a position (b), and paper is made to flow in a direction toward the conveying route (a retracting passage) A, not a regular paper conveying direction D. ON the other hand, the claw 5 is also being installed in each of conveying routes B and C, and when the jam occurs in a turnover device 3, the paper between these paper feeders 1 and 2 can be dropped to the conveying route B. In addition, when the jam occurs in a collating device 4, the paper is retracted at the conveying route C in the same manner. With this constitution, it is enough to eliminate the paper at the jam happening part alone so that jam handling comes so easy in consequence.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an invalid transfer paper processing method, and more specifically, to
The present invention relates to an invalid transfer paper processing method in a system including at least two or more transfer paper processing devices.

(Prior art) When a jammed transfer paper processing inability state occurs in a system equipped with a plurality of transfer paper processing devices, according to the conventional method, a jam occurs in one of the transfer paper processing devices in the system. The entire system is intended to stop immediately. In this method, all the paper being processed in the system is stopped, and several sheets of paper must be completely removed, which requires a great deal of effort on the part of the operator.

In addition, a method has been proposed in which when a jam occurs, the paper on the upstream side of the system is immediately stopped and the paper on the downstream side is ejected as is. This can significantly save the operator's effort. However, in this method, if the system consists of a paper feeding device, a recording device, a reversing device, and a collating device, if a jam occurs in the paper feeding device, paper that has already entered the recording device will are processed in the same manner as during normal operation, passed through a reversing device, and collated in a T-combining device.

On the other hand, when a jam occurs in the reversing device, the upstream side
That is, since the reversing device, recording device, and paper feeding device all stop, the operator has to not only clear the jam in the reversing device but also remove the invalid paper in the recording device and the paper feeding device, which is an inconvenience. arise.

(Objective) An object of the present invention is to provide an invalid transfer paper processing method that eliminates the inconveniences of the above-mentioned conventional methods and facilitates jam disposal by discharging invalid transfer paper as much as possible outside the machine when a jam occurs. It's about doing.

(Structure) In order to achieve the above object, the present invention provides at least two
In an invalid transfer paper processing method in a system equipped with two or more transfer paper processing devices, when a transfer paper processing inability state occurs in some of the devices in the system, the transfer paper processing device connected to the transfer paper processing device is The transfer paper processing apparatus is characterized in that the transfer paper being processed is evacuated at least on the upstream side of the processing apparatus.

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

FIG. 1 is a schematic explanatory diagram showing an example of a combination of systems for implementing the method according to the present invention, and this system includes a paper feeder 1
, transport device A, recording device 2, transport path B, reversing device 3,
It is composed of a conveyance path C1 and a collating device 4.

In the above configuration, if a jam occurs in the paper feeding device 1, the paper that has entered the recording device 1 is processed normally by immediately stopping the upstream side and ejecting the downstream transfer paper as it is. , passed through the reversing device 3 and collated by the combining device 4. On the other hand, if a jam occurs in the reversing device 3, the recorded value W2 is
can drop the paper between the paper feeder 1 and the recording device 2 into the conveyance path B, and the operator only needs to clear the jam in the reversing device 3.Similarly, when a jam occurs in the recording device 1, the paper can be dropped into the conveyance path B. A and, if a jam occurs in the collating device 4, the paper is evacuated through the conveyance path C.

In FIG. 0, which explains switching between normal processing and evacuation of the transfer paper in more detail from FIG. 2 showing branches of the conveyance path A, the conveyance path A is provided with a conveyance path switching claw 5. This conveyance path switching pawl 5 is always at position a, and when a jam occurs in the recording device 2 and paper feeding has already started from the paper feeder 1, it is switched to position b and switches to the conveyance path, that is, the evacuation path. It operates to flow the paper towards A. The arrow in the figure indicates the normal paper conveyance direction. Similarly, transport route B
and C are also provided with switching claws 5 in the same manner, and thereby, when a jam occurs in each device, the paper is evacuated to each conveyance path by the same operation as described above.

Next, electrical control of the above configuration will be explained using the functional block circuit shown in FIG. In the figure, 10 is a central processing unit (CPU), a read-only memory (RO
M)/random access memory (RAM), and an input/output port (Ilo>).In-machine communication means include paper feeder control means 11 and recording device control means 1.
2. It consists of a reversing device control means 13 and a collating device control means 14.

Each control means constituting the in-flight communication means, like the overall control means, has a central processing unit (CPU), read-only memory (ROM)/random access memory (RAM).
), and an input/output port (Ilo), and this output port (Ilo) is connected to a motor, craft, solenoid, sensor, etc. In the figure, only the paper feeding device control means 11 is shown in detail. Other control means similarly include a CPU ROM/RAM and an I10 port.

The operation of the control circuit will be explained using the flowcharts shown in FIGS. 4(a) to (6). FIG. 4 shows the operation of each device when a jam occurs in the reversing device 3. In FIG. 4, when a jam occurs in the reversing device 3, the overall control means 10 obtains a jam status input from the reversing device control means 13, as shown in the flowchart (a), and sends an error message to the host device (not shown). Output a message. Next, a paper feeding stop command is output to the paper feeding device control means 11,
A command for instructing the conveyance route B is output to the recording device control means, and a switching status to the conveyance route B is input from the recording device control means 12. It also outputs an immediate stop command to the reversing device control means 3, and obtains a paper feeding end status input from the paper feeding device control means 11 when the paper feeding device 1 is feeding paper. Furthermore, if the last paper that entered the machine from paper feeder 1 falls into conveyance path B, a correction calculation is performed to determine how many sheets of data have been lost, the status is input to the host device, and the jam display is turned on and the paper is fed. Outputs a normal stop command to the paper, recording, and T combining device control means.

In the flowchart (b), the paper feeding device control means 11
receives a paper feeding stop command input from the overall control means 10, and if paper feeding is in progress, outputs a paper feeding end status at the end of paper feeding. Next, a normal stop command is input from the overall control means 10, and the solenoid, clutch, and motor are sequentially turned off. In this flowchart, if paper is not being fed, a normal stop command is immediately input from the overall control means 10 to sequentially turn off the solenoid, clutch, and motor.

In the flowchart (c), the recording device control means 12
inputs an instruction command for the transport route B from the overall control means 10, and if it is the timing to switch to the transport route B, drives the solenoid for switching to the transport route B, and causes the overall control means 10 to switch the transport route B. Output the status. Ejection status output at each paper ejection timing (
(normal output). Next, a normal stop command is input from the overall control means 10, and the charger, solenoid, clutch, and motor are sequentially turned off (standby mode).
.

In the flowchart (d), the reversing device control means 1
3 outputs the hesium status from the overall control means 10, and inputs an immediate stop command from the overall control means 10 to stop the operation.

In flowchart 1-(e), collating device control means 1
4 outputs a discharge status output (normal output) at each paper discharge timing, and inputs a normal stop command from the overall control means 10, thereby sequentially turning off the solenoid, clutch, and motor.

As described above, according to the method of this embodiment, in addition to the conventional method of ejecting the paper as is on the downstream side when a jam occurs, it is also possible to eject the paper on the upstream side, thereby preventing a jam from occurring in the system. Since it is only necessary to recover the device, the operator does not have to consider the range of processing of invalid transfer paper.

In addition, based on the same idea as in the above-mentioned embodiment, when a paper jam occurs, all or part of the system is temporarily stopped, and after removing the paper in the jammed area, transport is restarted using a manually operated switch, etc. There is also a method for discharging paper, and it is also possible to use this method in combination. In this case, the liquid may be discharged to the end or may be discharged to an evacuation path that branches off in the middle.

Furthermore, it also serves as a jam prevention means when the power is not turned on downstream of the transfer paper processing device, and can be applied to electrophotographic devices and other devices that handle paper.

(Effect) According to this embodiment, when a transfer paper processing inability state (jam) occurs in some of the devices in the system, at least one of the transfer processing devices connected to the transfer paper processing device is To provide an invalid transfer paper processing method which has the effect of retracting the transfer paper in the middle of processing on the upstream side of processing, and has the effect of extremely easy jam processing because it is only necessary to remove the paper from the area where the jam has occurred. I can do it.
