Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field The present invention relates to an apparatus for automatically folding sheets, and more particularly to an automatic folding apparatus for folding a sheet 1- into two or two blades.

■Prior Art Automatic paper folding devices use folding rollers. For example, a first folding roller,
A second folding roller that contacts the first folding roller and a third folding roller that contacts the second folding roller are arranged, and the first folding roller and the second folding roller are disposed.
A paper folding guide path is arranged on the exit side of the folding roller.
.

1st from the paper input conveyance path. The paper that has entered the second folding roller enters the folding guide path. When the leading edge of the paper hits the paper stopper end at the end of the folding guide path, the first. The paper bends at the point where it leaves the 20th la, and this bending increases until it reaches the 2nd. The sheet is caught by the third folding roller and heads toward the discharge path.

(1) Purpose It is an object of the present invention to provide an automatic folding device of this type that allows for a plurality of types of folding of sheets such as paper, and allows selection and setting of folded and non-folded.

■Structure and ■Effects In order to achieve the above objects, the present invention includes a movable register inserted in the paper folding guide path, a register drive solenoid for driving the movable register to the paper stop position, and a register drive solenoid for driving the movable register to the paper stop position. A rotating arm is pivotally connected to the roller shaft body, a gate member is integrated with the first rotating arm, and a solenoid is coupled to the rotating arm, so that the gate member selectively controls the paper exiting the first and second folding rollers. According to this method, the folding position from the leading edge of the sheet is relatively short, with the movable register at the paper stop position. , set the movable register to the retracted position, select and set the fold with a relatively long fold position from the tip of sea 1'), and set the non-fold sheet passing with the gate member in the non-fold guide position, and the gate The origami paper with the member in the retracted position can be selectively set. As a result, it is possible to perform folding according to the input paper size, and it is also possible to perform multiple types of folding even for the same size. It is also possible to discharge the paper as is without folding it, allowing for digit selection.

In a preferred embodiment of the invention, one pivot arm has an engager, and the movable register has a latch member that engages the engager when not in the paper stop position to prevent the pivot arm from returning. The paper guide plate of the folding guide path has a flexible member at the end facing the folding roller.

According to this, once the rotary arm is driven to the plain paper passing position, the rotary arm is held in the drive position by the engaging element and the latch member, and there is no need to continue energizing the gate drive solenoid. It can be made small and power consumption is reduced.

By momentarily energizing the register drive solenoid, the gate member returns to the retracted position. Furthermore, the presence of the flexible member reduces the amount of paper folding at the folding roller portion, and allows the folding guide path to be set at a low angle.

Other objects and features of the invention will become apparent from the following description of preferred embodiments, taken in conjunction with the drawings.

7a to 7d show the control operation of the microprocessor 14 of the operation board control unit 10. The control operation of the operation board control unit 1o, that is, the control operation of the microprocessor 14 will be explained with reference to these drawings.

Referring first to FIG. 7a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) 14 initializes the input/output board, registers for temporary data storage, status registers (flags), and counters (program counters).
, timer (program timer), etc. (step 1). In the following, the word "step" will be omitted in parentheses, and only the step symbol will be shown.

After completing the initialization, the CPU 14 reads the status. First, it is checked whether there is a read flag (2
). At this point, initialization has just been completed and there is no read flag, so proceed to step 3 and set FQQ data in the operation board register. The standard data is: Paper size: A4 Digit selection: Unfolded portrait/horizontal orientation: Landscape Stamp position: Omm Publisher: 1st design (1st publisher's stamp) Drawing @: Temporary drawing (1st drawing type) Punch selection: This is a paper ejection selection without punching option. When this data set is completed, the indicator light corresponding to the data is lit accordingly. In this state, on the operation board 12, standby (this is set at initialization),
A4. No folds, horizontal, Omm, no punch, 1st design,
Indicator lights indicating each of the tray and temporary drawing are lit.

In Figure 6b, 3 is assigned to the operation boat register OBR.
Byte memory area (an area of the internal RAM of the CPU 14)
Indicates the tango position of data to be temporarily written to.

When the standard data is written to the operation board register OBR, a read flag is set (4). Next, referring to the state of the port that receives the input signal from the copying machine 800, the copying machine 800
0, it is determined whether a signal is transmitted or not (5). When there is a transmission, it is received, the signal and data are read, and it is determined whether the signal is a start signal or not (6). If it is not a start signal, it is determined whether it is an end signal or not7).If it is not an end signal, it is data, so among the input data, the data whose memory focus is assigned to the operation board register OBR is placed in the operation board register. Write BR update. When such update writing is performed, the operation board register O
Write 1 to the bit indicated as the copying machine input bit of BR. This 1 indicates that the copying machine 800 has given an instruction to the sheet processing machine 900 regarding how to process the sheet. Although not shown, the CPU 14
Data received from the copying machine and indicating what has been written to the operation board register OBR (indicating what the written data is) is held in the memory. If data is received from the copying machine 800 and writing to the operation board register ○BR is completed and the process proceeds to step 9, or if there is no input from the copying machine 800 and the process proceeds from step 5 to step 9, the operation is performed at this step. Read the key-ins on board 12. If the key-in is via the key switches 12a to 1'2e, refer to (10)-copier input bit.

If it is not 1 (data has not yet been received from the copier), the contents of the operation register are updated according to the key-in, and the indicator light on the operation board is turned on.

Update Off to match this update. For example, when the switch 12a is closed, the size designation bit of the operation board register OBR is updated to data indicating the next 83 of A4 at the moment it is closed, and the indicator light of A4 is turned off and the indicator light of B3 is turned on. do. When the key switch 12a is closed once when the size designation bit of the operation board register OBR is 7 in B5, the size designation bit is updated to data indicating A2, the indicator light of B5 is turned off, and the indicator light of A2 is turned off. Light. In this way, each time the size indication key switch 12a is closed, the lighting of one indicator light moves from the upper side to the lower side in FIG. The data is updated to indicate the size indicated by the light. However, this operation is performed only when the size data has not been received from the copying machine 800; if the size data has already been received, the process proceeds to step 11-12-■ and updates and displays the data in response to the key-in. No updates will be made. key switch 12
The CPU 14 performs a similar operation in response to a key-in by cm12h.

The reason why the input data from the copying machine 800 is given priority over the settings made by the operation board 12 is that the input data from the copying machine 800 is prioritized.
This is because data starting from 00 is more reliable. When no data is received from the copying machine (for example, when the copying machine is not connected), or when only part of the required data is received, the missing data is updated and set in accordance with the key input from the operation board I2. When no data is given from the copying machine and there is no key-in on the operation board 12, the setting data becomes the above-mentioned standard data. Although it is different from the step development of the illustrated flowchart, a start signal for the mechanism of the sheet processing machine to start operation is also received from the copying machine 800, and is also keyed in with the start key switch 12i of the operation board 12. However, when even part of the data is being received from the copying machine 800 (copying machine input pin of ○BR = 1), the key-in of the start signal by closing the switch 12i is not accepted in step 38. That's what I do. In this way, even when starting the processing mechanism, priority is given to the start signal from the copying machine.

The operation board 12 and its key-in reading/data set are meaningful when a copying machine is not connected, and when connected to a copying machine that does not transmit all required data, and when the sheet processing machine 900 is connected to an external device (host ) is not connected, or if the host has insufficient functionality, use key-in to compensate.

Now, if you set the data in step 8 (cent of received data from the copier), or if you set the data in step 13 (set key-in data), or the copier does not send data (5)L Maybe there is no key-in (9).

Proceeding to step 14 in FIG. 7b, the signal level of the signal receiving port from the unit 20 is referred to to see whether it is ready (paper can be accepted) or not (standby: paper cannot be accepted).

If the vertical fold & 9o turn control unit 20 is ready in step 14 of FIG. 7b, the unit 3 is ready in step 16.
Check whether 0 is ready or not. If the vane spar control unit 30 is ready, it is checked in step 18 whether the unit 40 is ready.

If the punch control unit 40 is ready, step 2
0, it is checked whether the unit 50 is ready. If the stamper control unit 50 is ready, it is checked in step 22 whether the unit 60 is ready. When the vertical conveyance & paper ejection control unit 60 is ready, all units are ready and can execute sheet processing, so the ready standby bit of the operation boat register OBR is set to 1 indicating that processing is possible) -L (24 ), the data in the operation board register OBR and the data in the previous operation board register POBR are compared (25). Note that since the previous operation board register OBR has been cleared during the initialization in step 1, the contents of the two do not match when the process proceeds to step 25 for the first time. This is for each unit 20 to 6 in steps 27 and below, which will be described later.
Processing mode data transfer to 0 is not being executed.

Therefore, first, in step 26, register the operation board register ○BR.
The data is updated and stored in the pre-operation board register POBR, and the process proceeds to setting the A version processing mode to the unit 20 (27) in FIG. 7C.

Setting the A version processing mode to the unit 20 in FIG. 7c (
In step 27), first, the size is determined from the data of the size designation bit of the operation board register ○BR (271).

If the town/size is A2, next refer to the OBR digit selection bit (
272-276). If there is no fold, please put A2 in unit 20.
- Send data indicating vertical/passing mode (273).

When folding into four, a signal indicating A2/vertical folding mode is transmitted to the unit 20 (275). When folding in half, data indicating A2, vertical, and passing mode is transmitted to the unit 20 (277). If it is JIS folding, data indicating A2/end face folding/JIS vertical folding mode is transmitted to the unit 20 (278).

If the size is not A2, the process advances to step 279 to see if it is A3.

If the size is A3, it refers to the length/width designation bit of the OBR, and if it indicates the height (280), it transmits A3/vertical/pass mode to the unit 20 (281).

If it indicates the side, refer to the digit selection bit of OBR (282), and if it is unfolded, unit 20
The A3/horizontal/passing mode is transmitted to (283). If there is an emergency, an A3/90'' turn mode is transmitted to the unit 20.

When the size is A4 (285), refer to the height/width specification bit (286), and if it indicates the width (286),
86), transmits the A4/horizontal/passing mode to the unit 20 (287). Unit 288 if it does not indicate the side
The A4/90'' turn mode is sent to (288).

When the size is the B version, in step 28, a mode corresponding to the size etc. is transmitted to the unit 20 in the same manner as in step 27 described above. Step 27 A2 to B3, A3 to B
4, and if A4 is read as B5, it becomes the content of step 28.

With the above, when unit 20 is ready, unit 10
A control operation mode instruction is given to the unit 20 from the control unit 20, and is set in the microprocessor of the unit 20.

The CPU 14 of the unit 10 then proceeds to setting the vane folding mode (29) in FIG. 7d. In this step 29, first, the digit selection bit of the operation boat register OBR is referred to (291, 292, 294). Then, when there is no fold, the size data is asked and a passage is transmitted to the unit 30 (295). In the case of four-fold, two-fold, and JIS fold, the data of the size designation bit and the data of the fold selection bit of the operation board register OBR are transmitted to the unit 30 (293, 296). As described above, control operation mode instructions are given to the units 10 to 30 and set in the microprocessor of the unit 30.

After completing the blade folding mode setting (29), the CPU 14 of the unit 10 sets the punching mode (30).

In this case, refer to the size specification bit data, fold selection bit data, and punch selection bit data of the operation boat register ○BR (301 to 306, 3
08, 309), When the final size is A4 and punched, send A4/punch mode to unit 40307), When the final size is B5 and punched, send B5/punch mode to unit 4031
0), otherwise the non-punch mode is set to unit 4.
Send to 0.

After completing the punch mode setting (30), the CPU 14 of the Ninit 10 sets the stamp mode (31).

In this case, the stamp selection bit of the operation board register ○BR is referred to (312), and if it is 1 indicating a stamp, the unit 50 is informed.

The OBR stamp selection bit, stamp position bit, publisher selection bit, and drawing type selection focus data are transmitted (313). A stamp selection bit of 0 sends a non-stamp signal to unit 50.

After completing the stamp mode setting (31), unit 10
The CPU 14 sets the paper discharge mode (32).

In this case, refer to the paper ejection selection bit of the operation board register OBR (321); if it is 1, it instructs the unit 60 to eject the paper to the sorter (323), and if it is 0, it instructs the unit 60 to eject the paper to the tray.1 (322).

After setting the paper ejection mode (32), two nits 20~
At step 60, the control operation mode has been instructed, and the CPUs of these units each hold the received instructions (mode data).

The CPU 14 of the unit 10 then returns to step 24 in FIG. 7b, and proceeds through step 24 to step 25.

Here, the data of the previous operation board register POBR is changed to the operation board register ○ by the execution of the preceding step 26.
Since it matches the BR data, steps 25 to 3
Proceed to step 3.

In step 33, all the indicator lights on the abnormality display panel 33 are turned off, the standby indicator lamp on the operation board 12 is turned off, and the ready indicator lamp is turned on. Next, a ready signal is output and set to the copying machine 800 (34). Then, the process returns to step 5 in FIG.
Wait for key-in.

When the start signal arrives from the copying machine 800 (6), refer to the ready/standby bit of the operation board register ○BR (35). If it is 1, normal operation is possible, so the units 20 to 60 are sent to the unit 20 to 60 at a predetermined timing. The start signals are sequentially transmitted (37).

Then, proceed to reading the status of the ST and Tsubu. Upon receiving the start signal, each of the units 20 to 60 starts driving the conveyance roller and waits for paper to arrive at each sensor. When paper arrives, predetermined control operations are initiated.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 20 waits (
If the unit 10 is unable to process (processing is not possible) or is on standby, the CPU 14 of the unit 10 reads this in step 14 of FIG. 7b and proceeds to abnormality processing (15) of the unit 20. In this abnormality processing, first, the copying machine input bit of the operation board register OBR is referred to (151). If it is 1, data is received from the copying machine 800, and since sheet processing has not yet started or has already started, an abnormality (standby) is sent to the copying machine 800 (152). Then, the ready/standby bit of the OBR is set to O indicating that the operation is disabled, the ready indicator light of the operation board 12 is turned off, and the standby indicator light is turned on (153). Next, the abnormality data is received from the unit 154 (154), and if the abnormal data indicates a paper jam, the abnormality display panel 13 corresponding to the position data is displayed.
Turn on the upper indicator light (156). When the abnormality data indicates that there is no paper jam, all indicator lights associated with the abnormality mechanism unit on the display panel 13 are lit (
157). Then, the process returns to the state reading after step 5 in FIG. 7a.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 30 waits (
If the CPU 14 of the unit IO reads this in step 16 of FIG. 7b, the process proceeds to abnormality processing (17) of the unit 30. This abnormality processing (17) is similar to the above-mentioned abnormality processing (15).

However, unit 20 in (15) should be read as unit 30.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 40 waits (

The operation of the blade folding mechanism unit 300 provided by the blade spar control unit 30 has been described in the mechanical description of the unit 300. Therefore, the explanation of the control operation of this unit 30 will be omitted here since it will be redundant.

The advantages of the embodiments described above are summarized below.

(1) In the blade folding mechanism unit 300, the folding rollers 318, 320, 322 for the first horizontal fold and the folding rollers 320, 322, 324 for the second horizontal folding are arranged at the same position,
Folding rollers 320 and 322 are used in common for the first horizontal folding and the second horizontal folding, and the paper input conveyance path (303) and the first horizontal folding conveyance path (305
), the second horizontal folding conveyance path (307), and the paper delivery conveyance path (3
09) are arranged in a criss-cross pattern with these crossbeam rollers at the center, and the angle between the paper input conveyance path (303) and the second cross-folding conveyance path is a small angle, and the first cross-folding conveyance path (305) ) and the paper delivery path (309) are made small, so the first transverse fold and the second transverse fold can be quickly performed in a small space.

(2) Whether or not to make the first horizontal turn is determined by the gate pawl 324 and the solenoid 332 that drives it, and these are small mechanisms and occupy a small space. Similarly, whether or not to make a second horizontal turn.

It is set up by a gate pawl 350 and a solenoid 358 that drives it, and these are also small mechanisms and occupy a small space.

The gate claw 324 is attached to the shaft of the roller 318, and the gate claw 350 is attached to the shaft of the roller 318.
are pivotally mounted on the shaft of the roller 320, and driving these to the transverse folding position and retracting from the transverse folding position is simple, and the control is also simple, as it only involves turning on and off a solenoid.

(3) The first horizontally folding conveyance path (305) and the second horizontally folding conveyance path (305)
07) can be manufactured with movable registers and fixed registers for each sheet of various sizes and various folds, and can handle many sizes and types of folds as shown in Figures 3a and 3b.
Select automatically. Since the movable register is solenoid driven, selection and setting of the register (size and fold) is easy.

(4) Arm 330 that drives gate claws 324, 350
．． 354 is provided with engagers 331, 355, latch claws 348, 368 are fixed to the movable register, and the solenoid 3
32, 358 to drive the gate claws 324, 350 to the non-folding setting position, the engagers 331, 355 engage with the latch claws 348, 368, and the arms 330, 354
Since the movable register is locked by its own weight, continuous energization of the solenoids 332 and 358 is unnecessary.

The lock is released by momentarily energizing the movable register drive solenoids 346, 370.

When driving the gate pawl, there is no crossbeam and the movable register does not need to be driven, and when retracting (unlocking) the gate pawl, there is a crossbeam and there is a high possibility that the movable register needs to be driven. The gate pawl latch mechanism, latch, and release operation are made by rationally utilizing the originally required mechanical elements and rationally utilizing the required operations.

(5) the tip of the lower guide plate of the first horizontally folded conveyance path (305);
In addition, flexible members 305 c and 307 c (5th b
(Fig.) are pasted to prevent the paper from being damaged.
Prevents paper jams on crossbeam rollers. In addition, the angle between the paper input conveyance path (303) and the second horizontal folding conveyance path is set to a small angle,
This is useful for making the angle between the first horizontal folding conveyance path (305) and the paper delivery conveyance path (309) a small angle.

(6) All the rollers in the paper input conveyance path (303) work together with the steel balls above them to feed the paper, and the steel balls are pivotally connected to an opening/closing plate that can be opened and closed with a hinge. . Therefore, the work of removing jammed paper is easy. In addition, it prevents uneven tension from being applied to the paper being pulled by the crossbeam rollers. This helps with horizontal folding along precise lines. Further, it is useful for changing the paper feeding speed (changing from low to high) between the paper input rollers 304 and 308 and the paper input conveyance path (303).

(7) A control unit 30 is provided corresponding to the blade folding mechanism unit 300, and an operation board control unit is provided,
The operation board control unit is the main control unit, the control unit 30 is the slave control unit, data indicating the paper size and fold type is given to the operation board control unit from the operation board and/or a host such as a copying machine, The folding processing mode is determined at , the processing mode of the control unit 30 is determined based on the determined sheet processing mode, and the processing mode is sent to the slave control unit 30 . therefore,
The control operation of the slave control unit 30 is relatively simple;
The slave control unit 30 may control the sheet folding process of the mechanical unit 300 assigned to it, determine paper jams and abnormalities, stop protection in the event of a jam or abnormality, and transmit this information to the main control unit.

(8) If the signals and data obtained from the settings of the host such as the copying machine 800 overlap with the signals and data obtained from the settings of the operation board, the operation board control unit prioritizes the former over the latter and extracts them. However, the signals and data that cannot be obtained from the host are assumed to be obtained from the settings of the operation board, and the data that is the basis for determining the processing mode is prepared.

When the sheet processing machine 900 is connected to a host such as a copying machine 800, the data given from the host is more reliable, and processing should be started in response to a start signal from the host. Therefore, the above-mentioned signal and data processing is rational and there are few errors in judgment and processing. Also, the operation of the host and the operation of the automatic folding device are synchronized or coordinated.

If the host is not connected, the automatic folding device operates according to input from the operation board, so the automatic folding device can be used alone.

(9) Based on the high-order digit data such as 4-fold, 2-fold, JIS fold, etc. and paper size data, the sheet processing machine 900
Since the lower fold types that need to be specified in the blade folding mechanism unit 300, such as folding and horizontal JIS folding, are automatically determined and automatically set, a large number of lower fold types can be set on the operation board or host. It is not necessary for the operator to set the processing mode easily.
