JPS5955775A - Apparatus for assorting double printing paper - Google Patents

Abstract

PURPOSE:To make it possible to automatically assort two printing papers to be printed in a superposed state, in a slip issuing machine, by performing work for respectively sending leading ends of said printing papers to an upper and a lower pinch rollers while distributing the same by the reversal in the rotary direction of a blade wheel. CONSTITUTION:When papers from a roll paper 1 for delivery to a customer and a duplicate roll paper 2 are set to rollers 9, 10 and a switch SW is turned on, a control apparatus conveys the paper 1 to the position of a sensor S1 by a motor M1 and at the same time, when a motor M2, an electromagnetic clutch C1 and motors M3, M4 are turned on and the leading end of the paper 2 is conveyed by the pintch roller 13 provided to the sending-out side of a printing part, the paper 1 is lifted up by a blade wheel 6 rotated to a clockwise direction to be sent to a wind-up roller 4 through a conveyor belt 5 and a pinted roller 15. When this wind-up is detected by a sensor S3, the motor M1 is turned on while the motor M4 is also turned on in a counterclockwise direction and the leading end of the paper 1 is turned down and grasped by a pintch roller 14 to complete setting. By this method, the assorting of the papers can be automatically performed in a simple structure.

Description

DETAILED DESCRIPTION OF THE INVENTION The distribution of double print paper used is device related.

BACKGROUND OF THE INVENTION In general, a slip issuing machine prints a slip to be issued to a customer and a slip for copy at the same time, the slip for the customer is cut to a fixed size, and the slip for copy is wound onto a roll. Both of these two sheets of printing paper are rolled long strips of paper, and in so-called autoloading, where one is loaded into the machine at the beginning of use, or one of the sheets is loaded when the paper runs out, conventional paper distribution is used. was difficult to automate and was done manually.

OBJECTS OF THE INVENTION It is an object of the present invention to provide an automatic sheet sorting device with a simple structure and to completely automate the automatic loading of a slip issuing machine.

Structure of the Invention Fig. 1 shows a slip issuing machine equipped with a device for distributing double printed paper according to the present invention.Printed paper 1 for issuing to customers 2 is printed paper for copying, and all of them are in the form of strips. It is a roll of paper. The printing paper 1 is conveyed by rollers 9 and 11 driven by a motor M1, and the printing paper is conveyed by rollers 10 and 12 driven by a motor M2.

Two sheets of reprinting paper 1 and 2 are overlapped and printed simultaneously by the dot printer 3, and then sent out by the print section delivery side pinch roller 13, and then the copy printing paper 2 is sent out by the conveyor belt 5 and the upper pinch roller 15. The printing paper 1 to be issued to a customer is taken up by a take-up reroller 4, sent by a lower pinch roller 14, and cut into a fixed size by a cutter 7.

8 is a feed belt for discharging slips. Immediately before the pinch roller 13 on the print section delivery side, there is an impeller 6 that can be rotated in both directions.
is provided, which is rotated clockwise by motor M4 when copy printing paper 2 is set by autoloading, and rotated counterclockwise when printing paper for customer issue is set. Motor M
3 drives the feed belt 8, the printing section delivery side pinch roller 13, and the lower pinch roller 14, and further drives the upper pinch roller 15 via the belt 5. Also motor M5
is for driving the cutter 7. When the cutter 7 is activated, the motors M1 and M2 are stopped, the electromagnetic clutch C1 is turned off, and the motor M3 drives only the belt 8 to release the customer's issue slip.

The winding roller 4 is driven by a motor M2 via a slipping clutch mechanism, so that the winding roller 4 always winds at a constant circumferential speed even if the winding diameter changes.

S1 is a sensor that detects the printing paper 1 for customer issue, and S2 is a sensor that similarly detects the printing paper 1 before the cutter 7, and also detects one slip at the same time.

S3 is a sensor that confirms that the copy printing paper has been taken up by the take-up roller 4. Figure 2 is an enlarged view of the distribution mechanism, and although it is omitted in Figure 1, the conveyance path of the printing paper is guided from top to bottom by guides Gl and G2. Print paper is smoothly conveyed from roller to roller. As shown in Figure 2, this guide is opened in the shape of a trumpet G3, and the leading edge of the paper is placed between the upper and lower pinch rollers 1.
It is set to be introduced smoothly on April 4th and 15th. Figure 3 shows the circuit of the slip issuing machine mentioned above.
U16 controls each circuit device according to a program stored in memory 17.

Signals from the issuing slip detection sensors S1 and S2 and the copy slip detection sensor S3 are input.

The output signal processing circuit 19 includes motors Ml, M2 . M3
, M5 and a forward/reverse rotation signal for motor M4, and also outputs a control signal to electromagnetic clutch CI.

Next, the automatic loading operation of printing paper will be explained with reference to FIG. First, the roll paper 1 for customer issue and the roll paper 2 for copy are loaded by the staff member, and the roller 9,
10 (step 20), and the autoloading start switch Sw is turned on (step 21). C
When the start switch signal is input, the PU 16 turns on the motor M1 (step 22), and transports the printing paper 1 for customer issue until the detection sensor S1 is turned on (step 23), at the position of the sensor S1. Motor M1 is turned off to stop paper conveyance (step 24).

At the same time, the motor M is activated by the signal from the start switch Sw.
2 (step 25), and then turn on the electromagnetic clutch CI.
By turning on the motor M3 (step 26), turning on the motor M3 (step 27), and turning on the motor M4 clockwise (step 28), the copy printing paper 2 set on the roller 10 is conveyed. When the leading edge of the paper 2 is conveyed by the pinch roller 13 on the output side of the print section, it is turned up by the impeller 6 driven clockwise by the motor, sent along the conveyor belt 5, and then turned over by the upper pinch roller 15. It is clamped and wound up on a winding roller 4. When a signal is input from the sensor S3 that detects that the copy printing paper 2 has been wound up (step 2
9) Turn off the motor M4 (step 30), turn on the motor M1 (step 31), and turn on the motor M4 counterclockwise (step 32). Thereby,
The leading edge of the customer-issued printing paper 1 that has been conveyed to the printing section delivery side pinch roller 13 is turned down by the impeller 6 driven in a counterclockwise direction, and the leading edge is turned over by the lower pinch roller 14.
In step 33), the motors Ml, M2 . M3. M4 and electromagnetic clutch C1 are turned off (steps 34 to 38), and the printing paper setting is completed.

As described above, the printing paper 1 is stopped by the detection sensor S1, and only the printing paper 2 is conveyed, and the leading edge of the paper is sent to the pinch roller 15 on one side by the rotation of the impeller 6 in one direction, and this is transferred to the detection sensor S3. After confirming this, the remaining printing paper 1 is conveyed, the impeller 6 is rotated in the direction of the paper, and the leading edge of the paper is sent to the pinch roller 14 on the other side.

Effects of the Invention According to the configuration of the present invention, there is an advantage that the work of feeding and distributing the leading edge of two sheets of printing paper to the upper and lower pinch rollers, respectively, can be performed automatically, and moreover, This system was realized using an extremely simple structure that reverses the direction of rotation of the wheel, so it is easy to control, and it is also possible to confirm the sorting of one sheet of paper before sorting the other. It has the advantage of being extremely reliable with no operational errors.
