JPS5932083A - Slip feed controller - Google Patents

Abstract

PURPOSE:To obtain automatically the best condition for the feed interval of a slip, by driving intermittently a motor by a timer after estimating the processing time needed for a sheet of slip and feeding intermittently the slip. CONSTITUTION:When a slip feed controller is started, the slips 101 on a hopper 100 are fed one by one by a belt driven by a motor 103. A motor 108 is also started simultaneously, and the motor 103 stops when the tip of the slip 101 is detected 104. However the slip 101 is carried to a reading part by a belt 106. The feed motor 112 of the reading part is equal to a stepping motor and drives intermittently a belt 111 synchronously with reading operation. A counter (not shown in the figure) measures the time during which the tip of the slip 101 is detected 109 and then the rear edge is detected 110. This measured value is stored, and the motor 103 is driven intermittently based on the data of the stored measured value. Thus the subsequent slips are fed successively. When the processing time is increased, motors 103 and 108 are stopped until the rear edge of the slip is detected 110. This ensures smooth and automatic feed of slips.

Description

[Detailed description of the invention] The present invention relates to a continuous feeding system for media.

K, which continuously feeds out forms from the form loading section (hopper section) at optimal intervals, was difficult to achieve in conventional systems. That is,
The time it takes for a form to be read at the form reading position varies depending on the design of the form. The factors include the total number of data contained in one form, the number of lines to be read, the length of the form, whether or not the form is packed-fed due to the presence or absence of reading retries (rescans), and the number of read characters.
i.

There are various options, such as whether or not the read data is checked.

A calculation formula is set for each document to determine the optimal document feeding interval by taking these factors into account.

It is extremely difficult to calculate and then determine the interval based on the result, as the formula becomes complicated, and therefore, it is necessary to feed at fixed time intervals that are common to customer records.

In the present invention, each form is actually fed in advance, the reading processing time per sheet is measured, and the result is set as the time interval for feeding the form, thereby allowing the form to be fed at the optimum time. Provide a means to achieve this. In addition, the present invention also includes means for stopping subsequent forms until processing is completed if, in rare cases, a specific form cannot be processed even after the set time has elapsed.

Next, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, a board 101 is a hopper freight 100.
It is mounted on top of. The IllFiC slip 101 is fed out by a pick-up roller 102, which is driven by a drive motor 103. This driving is stopped when the leading edge of the form is detected by the form detection unit 104. In this embodiment, this drive motor 103 can be turned on (1'F) at optimal time intervals.As a result,
The form that has reached the detection unit 104 moves on a conveyor belt driven by a drive motor 108 via a belt 107 and reaches a belt 111 driven by a drive motor 112 . Since the data on the form is read on this belt optically, for example, an image is formed on an image sensor 115 by a mirror 113 and a lens 114. The completed form is stored in the stacker 116. Midway detection units 105 and 109 are installed to detect that the leading edge of the form has reached that position, and detection unit 110 is installed to detect that the trailing edge of the form has reached that position.

Next, these control operations will be explained with reference to FIG.

The biting motion is started by receiving a start command from a computer or by inputting a start Hals signal 304 that is generated at the timing of pressing a start button or the like. Flip-flop 320 is set by signal 304, counter 310 is reset, flip-flop 315 is reset by the same signal passed through OR gate 314, and flip-flop 324 is set by the same signal passed through OR gate 325. The output of the flip-flop 315 set as a result is input to the drive circuit 316 of the drive motor 103 (FIG. 1), the drive row 2102 is driven, and the first form is fed out from a part of the hopper. The output of the flip-flop 324 set at the same time is input to the drive circuit 328 which drives the drive motor 1o8 (FIG. 1), and as a result, the conveyor belt 106 is also driven at the same time.

When the tip of the fed-out form reaches the detection unit 104, a detection signal is input to the terminal 306, and is input to the reset input terminal of the clip-flop 315 via the OR gate 329, and as a result of resetting the flip-flop 315, the drive The input to the roller 102 drive circuit 316 is turned OFF, and feeding of subsequent forms from the popper is stopped. However, at that time, the leading edge of the form reaches the conveyor belt 106 °C
Then, it further travels on the belt 106 and reaches the reading section.

The feed motor 112 of the reading section is usually a JC motor or a step motor, and performs intermittent driving operations for the bell 111.

When the form reaches the detection section 109, a detection signal from the detection section 109 is inputted to the terminal 301 and then inputted to the one-shot marbou vibrator 307. A clip-flop 308 is set by the output of the pie break 307, and the basic clock signal 302 is ANDed with the AND gate 309 and inputted as a clock signal to the counting counter 310. As a result, counter 310 starts counting time. after that,
After the document is read by the reading unit and ejected, when the trailing edge of the document reaches the detection unit 110, the detection signal is signal 303.
As a result, the output of the vibrator 318 resets the clip-flop 308, and the counting counter 310 continues counting until the clock signal output from the AND gate 3o9 disappears. That is, the counter 310 measures the time from the start to the end of reading in the reading section for one sheet of paper, and the counting result is stored in the register 311 at the same time as the reading ends. That is, the detection unit iio
As a result of the trailing edge of the form passing through, a signal 303 is generated, which is output from the AND gate 319 and input as a data set signal to the register 311. At this time, the signal 303
The output of the vibrator 318 generated by the
The knob 321 is set, and its output is ANDed with the basic clock signal 302 by an AND gate and inputted as the clock signal of the counter 322.
The counting of 22 starts δ, and the comparator circuit 312 compares the contents of the previously counted register 311 with the contents of the register 311, and when the two match, the vibrator 313 is output and the OR gate 314' (c-jJ flips the 70 knob). 315 is set, the drive roller 102 is driven, and the next form feeding can be started.Since the output of the vibrator 313 is simultaneously input to the reset terminal of the 7-rig flop 321, the counter 322 also starts counting. Stop.

Note that when the detection section 110 detects the trailing edge of the form, the output of the vibrator 318 is outputted through the C AND gate 319 and the delay circuit 333, and is input to the reset terminal of the flip-flop 320. Therefore, the contents of the counter 310 are not set in the register 311 again. The next time it is set is when the hopper is empty, the next group of forms is set in the rear hopper, and the computer issues a start command in the initial state. In this way, from the second sheet onwards, the comparison circuit 312 reads 1.
The drive row 2102 is driven every time the count result when reading the 1st form and the count result of the counter 322 match.

From the above, during continuous processing, when the trailing edge of a document is detected by the detection section 110, the leading edge of the next document has just reached the detection section 109, and reading processing can be performed one after another very efficiently.

Note that the input terminal 305 in FIG.
is generated, and the AND gate 326 performs an AND with the detection signal 301 from the detection unit 109.
It is connected to the reset gate of a flip-flop 324 that generates a drive signal for the drive motor 108 of 06.

This is because even if the next form reaches the detection unit 105, the preceding form is still being read by the reading unit.
If it is detected by 09, 7 lip 70 tsubu 3
This is to temporarily stop the feeding of subsequent forms by resetting 24. At the same time, or gate 3
Since the flip-flop 315 is also reset via 29, the drive roller 102 is also stopped, and the drive from part of the hopper is also stopped.

As described above, the present invention makes it possible to continuously feed documents while automatically setting the feeding interval to the best value.
