Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to clock synchronization of punching, printing and feeding operations in a paper card punching and printing device.

When punching and printing on paper cards are performed using the same device, the entire feeding path is constructed as shown in FIG.

The apparatus and operation of FIG. 1 will be explained in accordance with the flow of card processing.

First, the card 2 stored in the hopper 1 is transferred to the picker 3 according to the timing from the main clock (MC) counter.
is driven and fed one by one.

The card 2, which is fed at a constant speed by the rollers 4 and 5, is stopped by the brake plate spring 13 when the rear end leaves the roller 5.

At this time, the pinch roller 6.7 is in the off state.

The aligner 14 is driven and the card 2 is positioned.

The rollers 4 to 7, 11.12 and the eccentric shaft 15 are connected to one motor (hereinafter referred to as a main motor) by a synchronous transmission mechanism such as a toothed belt, and are constantly rotating.

A code plate 16 is attached to the eccentric shaft 15, and a main clock (
MC), and a sub-clock divided into even thinner parts (MC)
SC) is taken out, and the state of the device is represented by these two clocks.

The rollers 6.7 are driven via Geneva gears and perform an intermittent feed once per revolution of the eccentric shaft.

Furthermore, after the punch 17 descends and the punch blade hits the paper card 2 and punches it out, the time for stopping the intermittent feeding arrives during the time until the punch 17 rises and the blade comes out of the paper card 2. are synchronized so that

Further, the rollers 6/ and 7/ are pinch rollers, and are biased to restrain the card 2 when the paper card 2 is intermittently fed by an electromagnet or the like.

Rollers 8, 9.10 are driven by DC motors.

The roller 8' is a pinch roller and is energized by an electromagnet or the like at the start of card feeding.

That is, as soon as roller 7' is turned off, roller 8 is turned off.
' is turned on and feeding by the DC motor is started.

The sensor 18 is installed for the purpose of creating a timing to start counting the clock from the code plate 21 attached to the DC motor output shaft in order to stop the card 2 at a predetermined position, and detects the front end of the card 2. .

Therefore, when the front end of the card passes the sensor 18, the clock from the code plate 21 is counted and the card 2 is stopped at a predetermined position.

Wire dot print...\rad 20 can reciprocate in a direction perpendicular to the plane of the paper of FIG.

That is, reciprocating motion is performed using two pairs of electromagnetic clutches and brakes using power from the main motor.

A clutch that drives the carriage is turned on at a certain timing, and printing is performed in accordance with the printing position corresponding to the position of the carriage, and is ejected toward the platen 19.

When the desired number of lines have been printed, the DC mosita starts again and feeds the card 2.

By rotating the rollers 11 and 12 while moving the selection valve 22 up and down, the processed card 2 is stored in the slider 23 or 24.

As described above, in the apparatus shown in FIG. 1, all operations other than the print/carriage operation and the DCC morph operation are completely synchronously controlled using the main clock MCO as a reference.

Compared to the drilling operation, which is easy to synchronize to the main clock MC, the print carriage and DC motor have a separate power system or a clutch, making it completely synchronized to the main clock MC. That is difficult.

The object of the present invention is to provide a code board based clock (MC).

An object of the present invention is to provide a uniform paper card perforation printing device by completely synchronizing two clocks: SC), perforation feeding operation clock, and printing operation.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a book diagram of the clock synchronization system, FIG. 3 is a time chart of card feeding operation, and FIG. 4 is a flow chart.

Since the punching device is usually a synchronous machine, it is easy to synchronize card feeding and punching, and even in the device shown in FIG.
It is operated based on CO.

Therefore, in order to synchronize the printing operation with the drilling operation, the present invention performs control as shown in FIG. 2.

That is, when the print operation start signal SI for the last line of the print control PRCONT is sent to the punch feed control PF C0NT, the punch feed
The control PF C0NT sends back a response signal OK to the component control PRC0NT, and at the same time applies a reset signal R8T or a start signal STA to the main clock counter MCCTR and sub clock counter SCCTR.

The print control PRC0NT is a micro program that controls the carriage and DC feed, and the punch feed control PF C0NT
These are micro programs that control the drilling and feeding operations, and both of these programs are controlled by the counter MCC mentioned above.
By checking the contents of TR and SCCTR, it is possible to start at the same time.

The start is always performed at the home position of the main clock MC, and when printing N lines, the first main clock that arrives after detecting the print signal of the last line is set as MCO.

Further, when printing is not performed, the MCO is determined by a cycle of only drilling, which is controlled by a predetermined count value.

In this case, control is performed in short cycles, and the count value is, for example, MC16.

FIG. 3 is a time chart of the card feeding operation when the vertical axis represents the main clock MC and the horizontal axis represents the feeding distance.

The numbers on the horizontal axis indicate positions on the feeding path corresponding to FIG. 1, and the shaded area indicates the width of one card.

Three cards L2 and L3 are present in the feeding path at the same time, and each card operates simultaneously every time the eccentric shaft of the code plate 16 makes one rotation.

When the third card is fed out from the hopper 1 and reaches the position of the roller 4, punching of the second card is started,
At that time, printing of the last line of the first card is executed.

FIG. 3 shows the case where only one line is printed per card.

When printing multiple lines on one card, the other cards 2 and 3 do not operate when printing lines other than the last line.

The three cards started with the main clock MCO complete one cycle with the main clock MC18, and sequentially reach the roller 4 of the hopper 1, the punch 17 of the punching section, the head 20 of the printing section, and the smoother 23, 24. .

In addition, in FIG. 3, 25 is the protruding part by the picker, 26
is the aligning part, 27 is the Geneva feed part, 28 is D
The feeding portion by the C motor, 29.degree. 30 is also the feeding portion by the same DC motor, 31 is the end of print signal detection, 32 is the start of print signal detection, and 33 is the clutch on point.

Control of printing operation will be explained with reference to FIG.

When the DC motor starts (DC5TART), the passage of the sensor (SNS PS) is detected and the clock is set to 12.
After counting (RED 12LN), the carriage starts when the main clock MC appears (CRG
5TART).

Waits for the print signal (PR8GDET) and prints when it is detected, and if it is the last line (LASTLNPR),
A call is made to the punch control and the card is punched.

As explained above, according to the present invention, it is possible to easily synchronize the drilling and printing operations with the main clock, so that the drilling and printing functions can be performed by the same device, making unified control possible. Become.
