Abstract

PURPOSE:To obtain a paper conveyer for detecting malfunction of separation speedily and accurately by providing a cut form detected sensor, time setting, elapsed time counting means, and separation state discriminating means so as to detect malfunction state of separation automatically. CONSTITUTION:When a motor 10D is rotated, a cut form Ps can be conveyed in the direction of X. In this case, as a detecting signal S2 is outputted from a cut form detecting sensor 30 within a set time, separation state discriminating means 41-43 drive a good separation display 47-1. When a separation work malfunction on the case that a continuous Pc is hard and thick or a separation blade 21 descends slantingly, the continuous form Pc can not move in the direction of X as the position of the form Pc is restrained by an upstream conveyer roller 11U under a stopped state even if downstream conveyer rollers 11D-13D are rotated. That is, even if a counting time exceeds a set time, the detecting signal S2 is not outputted from the cut form detecting sensor 30. The separation state discriminating means 41-43 determine a separation malfunction and display it on a malfunction display 47-2. Thus, good or malfunctioning separations can be automatically detected speedily and accurately.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a paper conveyance device that intermittently transports continuous paper and ni-slip paper separated therefrom.

[Prior Art] A paper conveyance device is known that intermittently conveys continuous paper and Chinese slip paper created by separating perforations provided at a certain width on the continuous paper, and is used, for example, in a boarding pass issuing machine. Used in built-in h.

Such a paper feeding device generally has a structure as shown in FIG.

In FIG. 5, -IU is, for example, a paper kite that forms the upstream paper conveyance path RU from the storage box for continuous paper Pc (not shown) to separation units SP and R, and ID is from separation unit SPR to printing unit, etc. (not shown) is a paper kite that forms the downstream paper transport path RD.

Continuous paper Pc is transported by upstream conveyance roller 11U (motor 10
U) until it reaches the leading edge Po or a predetermined position PST (confirmed by the paper leading edge detection sensor 25). Downstream paper transport path F#
Sent into lRD. 20 is, for example, a continuous rotation motor,
It is a separating means consisting of a clutch, a cam, a solenoid, etc., and is a means for reciprocating the separating blade 21 in the Z direction to separate the perforations on the continuous paper Pc. Whether or not it has been separated is checked by a confirmation sensor 23 provided in the separation section SPH.

Then, while holding one sheet of cut paper Ps, the printing section etc. in the X direction\
When there is a command to transport, both motors iou.

10D is rotated to transport continuous paper Pc to paper conveyance length 1iR.
When the paper is sent to U and RD and the leading edge Po reaches the predetermined position PST, that is, it is detected by the paper leading edge detection sensor 25,
Both motors IOU and IOD are stopped and the perforation on the continuous paper Pc is positioned at the separating section SPH.6 After that, the separation blade 21 is moved back and forth once in the Z direction to separate the perforation. . Confirmation sensor 2 when separated
3 is activated, and the so-called cut sheet Ps having a length from the separating section SPR to a predetermined value HPST is conveyed in the X direction by rotating the motor 10D (conveying rollers IID, 12D, 13D). 6 [Problems to be Solved by the Invention] However, according to the above conventional structure, if the thickness or hardness of the continuous paper Pc changes, the separation of the perforations by the separation blade 21 may be insufficient or impossible. Cut paper Ps
There is a problem that the creation and conveyance of paper is obstructed, and also in this case, the continuous paper [゛c itself
Confirmation sensor 2 is tightened as it descends.
In case 3, it is determined that the separation is complete, resulting in a situation where the subsequent transport control etc. continue as is, resulting in poor work efficiency and a great deal of effort being spent on recovery.

Furthermore, when the separation blade 21 is installed in a device that is frequently used, if the separation blade 21 slants due to the condition of perforations or vibrations, separation failure will occur as well.

Furthermore, if used as a part of a boarding pass issuing machine, this application would cause not only a problem of malfunction of the paper conveyance device but also a social inconvenience of interfering with the entire boarding operation. People recognize that there is a problem in itself that, although conventional structures cause various problems when separation problems occur, separation problems cannot be detected until after these problems have occurred. In other words, if separation problems can be detected early, the countermeasures will be simpler and the analysis will improve smooth paper transport and work efficiency.

Such gaps occur regardless of the presence or absence of perforations.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper transport device that can quickly and accurately automatically detect separation failure.

Another object of the present invention is to provide a paper conveyance device that can automatically detect separation failure and, if separation failure is detected, actively and automatically perform the separation operation again.

[Means for Solving the Problems] The invention as set forth in claim 1 is characterized in that after the leading end of continuous paper fed along the paper transport path reaches a predetermined position, the upstream transport roller and the downstream transport roller are moved. Stop and operate the separation means x! In a paper conveyance device configured to separate L-sheet sheets and then rotate a downstream conveyance roller to convey the single-sheet sheets in one direction, the paper conveyance path is located downstream of the predetermined position on the sheet conveyance path. JI- arranged
A slip sheet detection sensor, a time setting means, an elapsed time counting means for counting the elapsed time from when the downstream conveyance roller is rotationally driven to start conveying the slip sheet, and a set time and a counting time. The present invention is characterized in that a separation state determining means is provided which outputs a separation failure signal when a detection signal is not inputted from the cut sheet detection sensor even after a counting time or a set time has elapsed.

Further, the invention as set forth in claim 2 is characterized in that a re-separation control means is provided for restarting the separation means based on a separation malfunction signal from the separation state determination means.

In the invention described in claim 1, the downstream conveyance roller is rotationally driven to convey the cut sheet in a predetermined direction after the separating operation by the separating means. Then, the elapsed time counting means counts the elapsed time from the start of this conveyance. At the same time, the separation state determining means monitors whether or not a detection signal from the cut sheet detection sensor is input, and outputs a separation failure signal if the detection signal is not input even after a counting time or a set time has elapsed.

Therefore, if the time setting means is set to an appropriate time determined based on the feed speed of the downstream IPI transport roller and the installation position of the cut sheet detection sensor, the time setting means can be set immediately in case of separation work or malfunction. Since it can automatically detect problems, optimal countermeasures can be quickly taken.

Further, according to the second aspect of the invention, when the separation malfunction signal is output, the re-separation control means restarts the separation means. At this time, by rotationally driving the downstream rpJ conveyance roller while the upstream conveyance roller is stopped, the separation blade can be pressed against the stretched continuous paper while keeping the perforation etc. fixed in position at the separation section. From this, reliable re-separation is possible.

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

(First Embodiment) As shown in FIGS. 1 and 2, this paper conveying device is provided with a Chinese slip paper detection sensor 30, a time setting means 45, an elapsed time counting means, and a separation state determining means, and a separating means 20 The system is configured to automatically detect a case where the separation work is unsatisfactory, and to notify the fact on the display unit 47.

Note that the paper kite IU, ID, and motor IO shown in FIG.
U, 10D, paper transport roller IIU, 11D to 13D,
The separation means 20 and the paper leading edge detection sensor 25f are the same as those mentioned above.
Since it is the same as the conventional example when used in the boarding pass issuing machine shown in the figure, the explanation of each will be omitted.

Now, as shown in FIG. 2, the cut paper detection sensor 30 is provided at a predetermined position R8T''') on the downstream paper transport path RD downstream from the installation position of the jammed paper leading edge detection sensor 25, and Side conveyance roller 11D.

Slip paper P sent by 12D, 13D (motor 10D)
This is a means for detecting the tip of s. Now, if the feed speed in the X direction in FIG. Side conveyance roller 13D
After one hour (T=L/V) has elapsed since the sensor was rotated, it is moved from the position of the sensor 25 to the position of the sensor 30.

Next, the time setting means 45, the elapsed time counting means, and the separation state determining means are configured to serve as a part of the drive control device 4o that drives and controls the entire boarding pass issuing machine. .

Therefore, the drive control device 4o will be explained first.
This drive control device 40 performs 9 calculations.

A CPU 41 having functions such as execution, a ROM 42 that stores a paper transport program shown in FIG. 3, a RAM 43 that temporarily stores various data, a keyboard 441, a display unit 47. It is formed of input and output boats 48° and 49, etc., and both conveyance rollers IOU.

10D, the separating means 20 as well as other engines 100 (printer section, part of the stacker, ribbon section, etc.) are controlled in a timely manner.

Here, the time setting means 45 consists of a specific switch (45) on the keyboard 44, and is for setting a set time Ts corresponding to the above-mentioned time T. Setting time Ts is RAM4
3 is stored.

Further, the elapsed time counting means operates at step 5T18 in FIG.
As shown in , after the separation work, the downstream conveyance rollers IID~1
It has a so-called timer function that counts the elapsed time Ti from the time when the 3D is rotationally driven and the cut sheet Ps begins to be conveyed in the X direction in FIG. In this example, the main CPU
41.

On the other hand, the separation state determining means uses the set time Ts and the counting time T.
i (ST24), and if the detection signal S2 from the cut sheet detection sensor 30 is not input even if the counting time Ti exceeds the set time Ts, a separation failure signal is output (ST2
6) CPU41, ROM42. RAM4
It is made up of 3rd grade.

In other words, after the separation work, the lower III 11m feed roller 11D~
13D is rotationally driven (ST18), and if the separation at the separating section SPH is complete, the leading edge of the cut sheet Ps will be detected by the cut sheet detection sensor 30 after the above-mentioned time T (set time Ts) has elapsed.
It should reach (ST20). In other words, if the detection signal S2 is not output from the cut sheet detection sensor 30 even after the set time Ts has elapsed, it can be determined that the separation has failed (ST2
4) YES judgment). This is because if the separation is not successful, the continuous paper Pc is braked by the stopped upstream 1llllI transport roller IILI, so the leading edge Po of the continuous paper Pc (in this case, it cannot be said to be the leading edge of the HL slip Ps) is This is because the side conveyance rollers 11D to 13D do not move even if they are rotationally driven.

In this embodiment, when a separation malfunction signal is output, a message to that effect is displayed on the display 47-2 of the display unit 47 (ST2
6>I, On the other hand, if 5T20 is determined to be YES and 5T24 is determined to be No, a good separation is displayed on the display 47-1 (ST22).

Of course, the separation malfunction signal can be used as a stop signal for the paper conveyance device or the entire boarding pass issuing machine.

Next, we will explain the operation of this embodiment 6. When there is an instruction to issue a boarding pass, the CPU 41 first sends the 10 grams stored in the ROM 42 to both transport rollers.
1U, 11D to 131) (motors 1OU, 10D) are rotationally driven (5TIO in FIG. 3). Then, continuous paper P
c is both paper strength IU.

The paper is sent along the paper transport paths RU and RD in FIG. 2, which form an ID. After a considerable amount of time has elapsed, the continuous form PC's fIA
Po reaches a predetermined position PST.

In this case, the paper leading edge detection sensor 25 works and the detection signal S
1 (ST12>, based on this signal S1, CP
U41 stops both motors IOU and IOD. In this case, the perforation on the continuous paper Pc is positioned at the separation portion SPH.

After that, the CPU 41 drives the separating means 20 (ST16
), the separation blade 21 is moved back and forth in the Z direction once, and the perforations are separated to separate the paper in the downstream paper transport path RD from the continuous paper Pc in the upstream paper transport path RU as cut paper Ps. Separate.

Therefore, only the motor IOD is rotated (ST18)
This allows the cut sheet Ps to be conveyed in the X direction in FIG.

In this case, since the cut sheet detection sensor 30 outputs the detection signal S2 within the set time Ts, the separation state determining means 4
1.42.43 drives the separation good indicator 47-1 (ST20.24.22).

By the way, if the continuous paper Pc is hard cardboard, or if the separation blade 21 is tilted and the separation operation is malfunctioning, the continuous paper Pc will stop even if the downstream conveyance rollers 11D to 13D are driven to rotate. Since the position is restrained by the upstream transport roller 11U, it cannot move in the X direction, that is, even if the counting time Ti or the set time Ts is exceeded, the detection signal S2 is not output from the cut sheet detection sensor 30.

As a result, the separation state determining means 41, 42, 43
It is judged as 80 at T24, that is, it is judged as separation failure, and failure indicator 4 is displayed.
7-2 indicates that. Alarms, etc. will be issued as necessary.

Therefore, it is possible to quickly and accurately automatically detect whether the separation is good or bad.

According to this solid line example, the cut sheet detection sensor 3
01 Time setting means 45. Elapsed time H several years (CPtJ4
1) Separation state determination means 4], 42° 43 are provided,
$ Vote F's #! 2. Since the system is configured to quickly and accurately automatically detect a separation failure state in relation to the feed speed, optimal countermeasures can be taken accurately and quickly, and conventional problems that cause inconvenience can be eliminated.

In addition, since the time setting means 45 is configured with one switch on the keyboard 44, it is easy to select and set the setting time, so that it has a wide range of applicability.

(Second Embodiment) In contrast to the first embodiment, which automatically detects separation failure and displays a message to that effect, this embodiment is more proactive by restarting the separation means 20. In addition, the device is configured to automatically release the separation failure state.

That is, in this paper conveyance device, after the separation operation as described above, the downstream conveyance rollers IID to 13D are rotationally driven to move the cut sheet Ps in the X direction. I wanted to,
In case of separation failure, the L
It is locked by the upstream conveyance roller 11U and pulled by the front or downstream conveyance rollers 11D to 13D.

In other words, in the separating section SPH, even if the sheet Pc slackens downward during the previous separating operation, the slack is automatically released. Therefore, the tension of the continuous paper Pc is stronger than at the beginning, and the tilting of the separation blade 21 has been stochastically eliminated.

This embodiment focuses on this point and is configured to automatically restart the separation operation several times.

For this reason, a re-separation control means is provided, and a restart number setting device is provided to increase the selectivity of the number of repetitions.

This restart count setting device is formed of a switch 46 with a keyboard 44, as shown by the dotted line in FIG.
, and the re-separation control means is 5T28, 30.3 in FIG.
ROM 42 and CPU that store programs as shown in 2.
It consists of 41. Note that the set restart count Ns is stored in the RAM 4B.

In the second fiber example of such a configuration, 5TIO to 26 in FIG.
Up to this point, the operation is the same as in the case of the first embodiment (FIG. 3), and a separation malfunction signal is output from the separation state determining means 1441, 42, 43 (ST24.26>, and the re-separation control means 41 .42 drives the rotational separation means 20 stored in the RAM 43 and repeats the operations below 5Ti6 (
ST28゜30). If the separation is successful, a message to that effect is displayed (ST22>), or if separation is not possible even after restarting, the non-separable indicator 47-1 is driven (ST22).
32) L, further stop this device if necessary.

Therefore, according to this second practical example, the separation malfunction can be positively and automatically canceled by restarting the separation means 20.

In the above embodiments, it is assumed that the continuous paper Pc is provided with perforations, but the present invention is also applicable to the case of continuous paper Pc without perforations.

[Effects of the Invention] According to the invention described in claim 1, the JIL form detection sensor interval setting means, the elapsed time counting means 1 and the separation state determination means are provided to automatically detect a separation failure state. , it is possible to eliminate problems that cause inconveniences caused by post-discovery in conventional devices, and it becomes possible to take quick and accurate countermeasures.

Further, according to the invention set forth in claim 2, in addition to the invention set forth in claim 1, a re-separation control means is provided to perform the separation work again, so that separation failure can be more actively and automatically performed. can be removed.
