Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sheet processing device that automatically folds a sheet such as paper into a predetermined shape regardless of its input orientation.

■Prior Art For example, copies of various sizes can be obtained using conventionally used blueprints (diazo copies) and recent electrophotographs (transfer type copies).

Generally, A-size copies larger than A4 should be folded into A4, and B-size copies larger than B5 should be folded into B.
Fold into 5.

Conventionally, this type of sheet folding process is performed manually, which requires a lot of work, and it is not always possible to obtain an accurate folded shape. Many people do not know the folding method, and it takes a lot of effort and time to correct the shortcut method.

■Purpose The present invention provides a sheet processing device that automatically performs predetermined folding regardless of the orientation of a single sheet of paper.
The porpose is to do.

(2) Structure and (2) Effects In order to achieve the above objects, the present invention includes a first paper folding mechanism, a 90° turn mechanism, and a second paper folding mechanism, which are arranged in this order.

It is equipped with a control means that reads the status of the electrical elements of these mechanisms and controls the energization, and automatically performs the first type of folding of the paper, the 90 @ turn when the orientation is different from the expected one, and the second type of folding. Do it sequentially.

According to this, for example, when the first type of fold is an edge fold (triangular fold at a corner part) and a vertical fold for JIS folding, and the paper input orientation is vertical or horizontal, a 90° turn mechanism is used. Automatically rotate the paper to change its vertical and horizontal position. JIS folding can be performed using the second type of folding as feather folding.

Furthermore, as shown in the examples, folding in two, folding in four, etc. is also possible.

Furthermore, as shown in the embodiment, by adding a movable positioning member, it is possible to selectively perform automatic folding of various sizes of the A version and the B version.

1 paper unit 700 (1) When ejecting paper to tray ET is instructed,
With the paper discharge gate claw 712 set at the position shown by the solid line, the incoming paper is delivered to the tray ET.

(2) When the paper discharge to the sorter 1000 is instructed, the paper discharge gate claw 712 is set to the position indicated by the two-dot chain line, and the incoming paper is sent to the sorter 1000.

Next, the configuration of each mechanical unit will be explained with reference to FIGS. 5a to 11.

First, the configuration of the vertical folding mechanism unit 100 will be explained with reference to FIG. 5a.

The vertical folding mechanism unit 100 includes a paper entry roller 104 and a paper entry gate claw 112.3 that determines the feeding direction of the 1082 paper.
vertical folding rollers 116, 118° 120, vertical folding conveyance rollers 162, 166, and end folding folding plates 197. Equipped with registers 154, 156, etc. for setting vertical folding position,
The required rollers are coupled to a drive power system (not shown) of unit 100.

The paper entry gate claw 112 is fixed to the rotating shaft 110,
This rotating shaft 110 is rotationally driven by a solenoid 114. When vertical folding is not instructed, solenoid 114
In this case, the paper entry gate 112 is placed in the solid line position shown in the figure without being energized. In this state, the paper sent directly below the paper sensor 174 is received by the rollers 104 and 108, but the claw 1
Unit 2 hits the bottom surface of Unit 12 and is bent downward.
Go straight to 00. When vertical folding is instructed, when the sensor 174 detects paper, the solenoid 114 is energized and the tip of the claw 112 descends toward the lower roller shaft 106 (the state shown by the two-dot chain line in FIG. 4).

In this state, the paper sent directly below the sensor 174 is
The paper is received by rollers 104 and 108, rides on the upper surface of claw 112, and is sent toward vertical folding rollers 116 and 118°120.

Vertical folding rollers 120 and 118 are in contact, but roller 116 does not contact 120 in any state.

The vertical folding roller 116 is supported by a shaft 122 and is rotatable about the shaft. A plunger of a solenoid 124 is connected to the arm to which the roller 116 is pivoted, and when the solenoid 124 is energized, the roller 116 is
is separated from roller 118, and paper that has passed through the upper surface of pawl 112 can enter between rollers 118 and 116. When solenoid 124 is de-energized, roller 116 is
181'.

The fixed register 178 is for positioning the short side of A2 when vertically folding, and the fixed register 154 is for positioning the short side of A2 when vertically folding A2/quarter-folding.
The movable register 126 for long side positioning is B3 during vertical folding.
The positioning of the short side and the movable register 56 are B3
・For positioning the long side of B3 when vertically folding into four.

Plungers of solenoids 130 and 160 are connected to movable registers 26 and 156, respectively. When solenoid 130 is de-energized, register 2
6 is retracted from the vertical origami paper transport path. Solenoid 130
When energized, the register 26 advances into the longitudinal folding paper transport path and stops the incoming paper there. Solenoid 160
When the register 56 is not energized, the register 56 is retracted from the vertical folding paper transport path. When solenoid 160 is energized.

A register 56 advances into the longitudinal folding paper transport path and stops the incoming paper there.

Rollers 66 and 162 are connected to rollers 04 and 10 when solenoid 124 is energized and roller 16 is pulled up.
After the leading edge of the paper that is guided through the upper surface of the claw 112 at 8 and sent to the register 78 or 126 is applied to the register mig 178 or 126, the solenoid 124 is de-energized; The paper is sandwiched between vertical folding rollers 116 and 118. In this state, the paper is moved to register 154 or 1 by these rollers 116 and 118.
56, one side of the paper is sent to register 154 or 1
56, the paper is deflected at the point where it passes between the rollers 116-118, and this deflection increases until the paper hits the roller 118-1.
It is caught between 20 and folded vertically in half, and the roller 118
, 120 (a slit-shaped opening parallel to the axis of the vertical folding roller) to the unit 200.

The roller 166 is rotated so that the rotation of the rollers 166 and 162 does not provide resistance to the movement of the paper during such vertical folding.
A steel ball 169 is placed on the roller 162, and a steel ball solenoid 164 faces the roller 162.

The steel ball 169 is supported by a ball support (not shown) so as to be rotatable in multiple directions, and is always in contact with the roller 166, and when paper arrives, it presses the paper against the roller 166 with its own weight.
Rotates as the paper moves. Therefore, when the paper is moving directly under the vertical folding roller 116 in the axial direction of the roller, one sheet of paper that is driven in that direction by the rotation of the roller 116 is moved in the direction perpendicular to the axis of the vertical folding roller 116. When moving (lengthwise folding in two), the steel ball 169 rotates as the paper moves, so it does not interfere with the movement of the paper.

The steel ball solenoid 164 has a structure in which an electric coil is wound around a magnetic core, and when the electric coil is energized, the steel ball 165 is attracted to the core and separated from the roller 162. steel ball 1
65 has roughly the same effect on the paper as the steel ball 169, but when the paper is driven in a direction perpendicular to the axis of the vertical folding roller 116 (folding in two vertically), the steel ball 65 is activated by energizing the electric coil. 16
5 from the roller 162 (paper) and
reduce frictional resistance.

The folded plate 197 is fixed to a carriage 198, and this carriage 198 is connected to the guide bar 134.

It is guided so as to be able to reciprocate in the direction of the arrow (the axial direction of the roller 116). The carriage 198 has a link arm 196
is pivotally connected to this link arm, and another link arm that is pivotally connected to this link arm is fixed to the output shaft of the half-rotation clutch 136. The gear fixed to the input shaft of the half-rotation clutch 136 is.

It is engaged with a drive power system (not shown) of unit 100. When the half-rotation clutch 136 is energized, it rotates the link arm 196 half a turn clockwise to drive the carriage 199 (that is, the folded plate 197) to the right, and when the energization is cut off, the half-rotation clutch 136 rotates the link arm 196 in the opposite direction. The carriage 199 (that is, the folded plate 197) is driven to the left by making a half turn clockwise.

FIG. 5a shows the folded plate 197 in the standby position.

To the right of the folded plate 197 is a push plate 138. This push plate 13
8 is fixed to the U-shaped arm 140, and arm 1
40 is pivotally mounted to a carriage 142. The carriage 142 has a guide bar 193 parallel to the guide bar 199.
It is guided so that it can freely move back and forth. An arm 146 is fixed to the carriage 142, and the tip 1 of the arm 146 is fixed to the carriage 142.
95 protrudes into the path of the l'' carriage 198. A roller 152 abuts the U-shaped arm 140, and the roller 152 is pivotally attached to one end of the pivot arm 148. At the other end of 148,
A plunger 150 of a solenoid 150 is coupled. In the state shown in FIG. 5a (standby state), the U-shaped arm 140 is held loosely by the roller 152. The push plate 138, in which the U-shaped arm 140 is fixed to the U-shaped arm 140 in a dogleg shape, is lifted upward by a spring 145 (leftward pull) and a spring 144 (upward pull). . In this state, rollers 116-118
The paper fed between them passes through the space between the folded plate 197 and the push plate 138. When solenoid 150 is energized, arm 1
48 rotates counterclockwise, and the roller 152 rotates the arm 14.
Press 0 firmly. As a result, the U-shaped arm 140 rotates counterclockwise, and the entire pressing plate 138 becomes lower than the upper surface of the folding plate 197, pressing the paper downward. When the half-rotation clutch 136 is energized in this state, the folding plate 197 moves to the right and bends the paper as it passes over the push plate 138. When the folding plate 197 moves to the right to some extent, the carriage 198 pushes the tip 195 of the arm 146 to the right, which causes the push plate 138 to also move to the right. U-shaped arm 1
40 comes off the roller 152 to the right, the roller 152 prevents the U-shaped arm 140 from returning to the left.

If the energization of the half-rotation clutch 136 is cut off in this state,
The folded plate 197 returns to the standby position shown in Figure 5a. When the solenoid 150 is de-energized, the U-shaped arm 140 pushes up the roller 152 by the force of the spring 144, and as a result, the push plate 138 moves upward and the spring 14
It moves to the left with a force of 5 and enters the standby state shown in FIG. 5a.

Fig. 5b shows an enlarged plane of the folded plate 197, and Fig. 5c shows its v.
A cross section along the c-vc line is shown, and FIG. 5d shows a cross section along the VD-VD line. The edge of the folding plate 197 on the pushing plate 138 side has a substantially knife-like shape with an inclined lower surface (dotted line), making it easy to fold and hold the paper PR (double-dashed line). Further, the tip of the folded plate 197 has an oval shape to prevent the paper from escaping. When A2 paper is positioned using the register 178 and when B3 paper is positioned using the register 126, the first corner of the paper PR (double-dashed line) is the fifth corner.
As shown in Figure b, the paper PR is triangular and rests on the folded plate 197, and the paper PR is between the folded plate 197 and the push plate 138. This state is shown in FIG. 5e.

In this state, when the solenoid 150 is energized, the paper is pressed against a lower paper guide plate (not shown) by the press plate 138. When the half-turn clutch 136 is energized, the folding plate 197 moves to the right as shown in FIG. 5f, folding the corner of the paper over the push plate and the paper above it. Folded plate 197
As the paper progresses further, the push plate 138 also moves to the right, and the push plate 138 comes out of the folded portion of the paper to the right. When the half-rotation clutch 136 is de-energized, the folded plate 197 moves to the left as shown in Fig. 5g, and finally returns to the standby position (Fig. 5e). When the solenoid 150 is de-energized, the push plate 138 returns from the position shown in FIG. 5g to the standby position (FIG. 5e) by the force of the spring 146. At this time, the push plate 138 moves upward due to the action of the spring 144 and does not come into contact with the folded corner piece of the paper PR.

Although not shown, a fixed register 154 used for vertically folding in half for A2/4 folding and a movable register 156 used for vertically folding in 2's for 83/4 folding are parallel to The movable register (154J) and B3
Movable register (156J) used for vertical two-folding for JIS folding
) are installed, and each solenoid (160AJ, 16
0BJ: not shown), the rollers 108 are selectively advanced into the paper transport path, but the illustrations are omitted in FIG. 5a because the drawing becomes complicated. It is connected to the main power system (not shown) of the unit and constantly rotates while the main power system is in motion.

The rollers 162, 166 and 118 and half-turn clutch 136 human power system are all selectively connected to the main power system through one clutch. The main power system starts moving in response to the start signal,
It stops when a predetermined condition is met. For example, it is stopped when an end signal arrives, when a predetermined time has elapsed since the sensor 174 stopped detecting paper, or when a paper jam occurs. The clutch is energized when A2/4-fold mode, A2/JIS fold mode, B3/4-fold mode, and B3/JIS fold mode are set.

When a paper jam occurs while the unit 100 is in a state where the solenoid 114 is off), the roller 04 is separated from the roller 108 to remove the jammed paper. Vertical fold mode (Solenoid 1

The paper is driven towards registers 262,264.

When the edges of the paper come into contact with the registers 262 and 264, the paper will bend slightly, but this bend will not become large because the pressing edge provided by the steel ball is small and the steel ball itself will not apply any driving force to the paper.

A wire 227 is fixed to the carriage, and the wire 227 is stretched around an idle pulley and a drive pulley. A drive pulley is coupled to the rotating shaft of motor 229. When the motor 229 rotates forward, the cutter 223 moves to the position shown in FIG. 6a! (front standby position) to the back a distance slightly longer than the length of the short side of A2, thereby cutting the jammed paper. When the motor 229 reaches this distance, the motor 229 is once stopped, and then the motor 229 is reversely energized until the switch 231 is closed, and the motor 229 returns to the standby position shown in the figure.

The axes 246 and 258 of No. 2 and 254 are inclined in a direction perpendicular to the paper feeding direction (the direction in which the axes 248 and 260 extend), respectively. For this reason, the shafts 246 and 258 are coupled to the shafts 248 and 260 by a universal joint mainly composed of springs. As a result, roller 246
and 254 apply a force to drive one sheet of paper toward registers 264 and 266 (driving force toward register 264).

Note that the register 266 is provided to adjust the orientation of the paper. As will be described later, in the unit 200, all the sheets of paper are adjusted in posture and position so as to be aligned with the registers 262 and 264, and a register 266 is provided to ensure this more accurately. register 266
The plunger of the solenoid 270 is connected to the
When the solenoid 270 is energized, the register 266 lowers and retreats from the paper conveyance path. During the edge alignment drive, the register 266 is advanced into the paper conveyance path, and after the edge alignment drive is finished and one sheet (discharge) drive is started, the entire leading edge of the paper reaches the register 266. solenoid 2
By energizing the register 70 and retracting the register 266, the posture of the paper is adjusted.

Since the paper is being pressed at 2°254, etc., there is no tension on the paper that would cause it to tear.

Next, details of the operation of the 90° turn mechanism unit 200 will be explained with reference to FIG. 6a.

(1) A3/horizontal/JIS folding or two-fold mode--In these modes, the unit 200 changes the A3/horizontal orientation to the A3/vertical orientation, as shown in FIG. 3a. Paper is fed from unit 100 between rollers 204-208.

When the sensor 217 detects paper, the steel ball solenoid 220
．． The steel ball solenoids other than 228, 224, 232, and 274 are energized to pull up those steel balls. The paper is fed by the rollers that are in contact with the steel ball solenoids 220, 228, 224, 232, and 274, and rollers 208 and 204. It will be done. Further, counting of pulses of the encoder 297 is started.

When the count value reaches the predetermined value assigned to A3, 90''
The turning steel ball solenoids 240 and 236 are de-energized, and the rollers 234 and 238 apply rotational force to the paper. This causes the paper to rotate as shown in Figure 6b. That is, a rotational force in the direction of the arrow shown by the circular arc is applied to the paper that has entered the rollers 234 and 238 in the posture shown by the dashed-dotted line in FIG. 6b, and the paper rotates toward the posture shown by the dashed-double line. When the count value reaches the second value assigned to A3, solenoid 270 is energized and register 2
66 enters the paper transport path. When the count value reaches the third value assigned to A3, the 90'' turn should have been completed, so the steel ball solenoids 236 and 234 are energized so that no rotational force is applied to the paper.Count value is the fourth
When the value reaches , the steel ball solenoids 278, 295, and 291 are de-energized and the paper is driven toward the register 264. In this state, the paper is driven to the position shown by the three-dot chain line in FIG. 6b while maintaining the posture shown by the two-dot chain line, that is, to the position where the entire negative side is in contact with the registers 262 and 264.

A paper input conveyance path that sends the paper from the unit 200 to the horizontal folding rollers, a first folding conveyance path that positions the paper for the first folding with the horizontal folding rollers, and a second folding path with the horizontal folding rollers. 9 a second folding conveyance path for positioning the paper in order to This is a second gate pawl 350 that controls the supply of paper from the folding rollers to the second folding conveyance path.

The paper input conveyance path includes rollers 304, 308 and rollers 310, 312, 3 that receive paper from the unit 200.
There are 14,316 etc. The rollers 304 and 308 rotate at the same speed as the rollers 207 and 211 of the unit 200, but the rollers after roller 310, including the transverse folding roller, rotate at a faster speed. Note that when one end of the long side of A2 reaches the horizontal folding roller, the other end reaches the roller 304,
308 has already been passed. A sensor 386 detects paper on the incoming paper transport path.

A rotating arm 328 is pivotally attached to the shaft 326 of the horizontal folding roller 318, and a first gate pawl 324 is fixed to this rotating arm 328. A drive arm 330 is engaged with a pin erected on the rotating arm 328. The drive arm 330 is pivotally connected to a shaft 334, and the drive arm 330 is
30 is rotationally driven by a solenoid 332. When solenoid 332 is de-energized, tension spring 391
The rotating arm 328 is pulled upward by the force of
As a result, the tip of the drive arm 330 is also pulled upward. Engagement element 3 fixed to drive arm 330
31 is above the latch pawl 348.

When the solenoid 332 is energized, the drive arm 330 rotates clockwise, the five-turn arm 328 rotates counterclockwise, and the first gate pawl 324 rotates between the transverse folding rollers 318 and 322.
During this period, it descends and faces the transverse folding roller 320 (transparent position). Further, due to the rotation and descent of the drive arm 330, the engager 331 comes out below the latch claw 348, and the latch claw 348
is located above the engaging element 331, and the engaging element 331 is prevented from rising. In this state, even if the energization of the solenoid 332 is stopped, the first gate pawl 324 remains in the transparent position. When the solenoid 346 is energized, the latch pawl 348 returns above the engagement member 331, so that the drive arm 330 can return upward.

When is not energized, the rotating arm 352 is pulled upward by the force of the tension spring 392, and thereby the tip of the drive arm 354 is also pulled upward. An engager 355 affixed to the drive arm 354 is above the latch pawl 368 .

When the solenoid 358 is energized, the drive arm 354 rotates counterclockwise, and the rotary arm 352 rotates clockwise, causing the first gate small 350 to move across the folding rollers 320 and 324.
The engaging element 355 falls below the latch pawl 368 due to rotational descent of the drive arm 354, and is opposed to the horizontal folding roller 322 (transparent position).
is located above the engaging element 355, and the engaging element 355 is prevented from rising. In this state, even if the solenoid 358 is de-energized, the second gate pawl 350 remains in the transparent position. When the solenoid 370 is energized, the latch pawl 368 returns above the engagement member 355, so that the drive arm 354 can return upward.

The first fold conveyance path is a conveyance path that guides the paper fed out by the horizontal folding rollers 318 and 320, and there is a movable register 336° A3/JI which determines the first fold position of the B4/JIS fold.

When the first gate pawl 324 is in the clear guide position (located between the rollers 318 and 322 and facing the roller 320), the paper that is about to be sent out toward the first fold conveyance path by the transverse folding rollers 318 and 320 is.

The first gate pawl 324 is guided between the horizontal folding rollers 320 and 322 and does not go toward the first folding conveyance path. At step 320, the paper is sent out toward the first folding conveyance path. At this time, the leading edge of one sheet is in the register (336, 338, 340 or 34) on the first folding conveyance path.
2), the paper begins to bend on the exit side of the rollers 318 and 320, and when the amount of bending increases to a certain extent, the paper becomes double and gets caught between the rollers 320 and 322. This means that horizontal folding has been performed.

The folding position is determined by which register extends into the conveyance path.

The second folding conveyance path is a conveyance path that guides the paper fed out by the horizontal folding rollers 320 and 322, and here, B3/JIS

A fixed register 364 is arranged for determining the folding position in horizontal two-folding of four-folding. Movable register 358,
360 and 362 each have a solenoid 338S
(not shown), 370, and 3625 (not shown) are connected, and are retracted from the paper conveyance path when the solenoid is de-energized. When the solenoid is energized, it advances into the paper transport path and stops the paper from moving.

When the second gate pawl 350 is in the through-guiding position (located between the rollers 320 and 324 and facing the roller 322), the paper to be sent out toward the second folding conveyance path by the horizontal folding rollers 320 and 322 is When the second gate pawl 350, which is guided between the horizontal folding rollers 322 and 324 by the second gate pawl 350 and does not go toward the second folding conveyance path, is retracted from the clear guide position, the second gate pawl 350 is guided between the horizontal folding rollers 322 and 324. 3
At 22, the paper is sent out toward the second fold conveyance path. At this time, the leading edge of one sheet is in the register (35
8, 360, 362 or 364), the paper begins to bend on the exit side of the rollers 320 and 322, and when the amount of bending becomes large enough, the paper doubles and passes through the rollers 322 and 322.
It is included in 324. This means that horizontal folding has been performed.

The folding position is determined by which register is advanced to the second folding conveyance path.

The paper is sent out by the transverse folding rollers 322 and 324.

The roller 374 and the roller that contacts it send it out to the punch mechanism unit 400.

As shown in FIG. 7c, when the paper is fed into the first folding conveyance path by the first transverse folding roller 318 and the second transverse folding roller 320, the leading edge of the paper hits the lower paper guide plate 305b. As shown by the dotted line in FIG. 7c, if the curl at the leading edge of the paper is large, the lower paper guide plate 30
There is a possibility that it will collide with the tip of 5b. In order to prevent a collision, the guide plate 105b may be extended toward the transverse folding roller. However, as shown in FIG. 7d, after the second transverse folding roller 320 and the third transverse folding roller 322 have folded the paper, the paper is conveyed while rubbing against the tip of the guide plate 305b. Therefore, the paper is easily damaged, and the flexible member 305C prevents this. This flexible member 305c prevents the paper from colliding with the tip of the guide plate 305b and reduces damage. Another effect of the flexible member 105C is that the guide plate 105a,

Indicates the status, the date can be changed in this status. Although the date is adjusted manually in this way, the 1st date on the base frame 502 and the date on the stamper 556 are set using a solenoid or the like by using a roller for changing the 1st date in a position that can face the changing axis. Provided so that it can be driven forward and backward 1
When changing the date, drive the motor 520, set the date stamper in a position facing the changing roller, push out the roller, press the date against the changing shaft, and drive the roller to rotate. Good, if you do this, the date can be changed automatically. Further, a driving mechanism may be coupled to the base frame 502 to automatically drive the base frame 502 in a direction perpendicular to the feeding direction of one sheet.

Open it in the direction of arrow 605 and take out the paper. When jammed paper straddles units 600 and 700, turn the handle 634 to pull the paper into unit 600, pull out unit 1-600 from the main body of sheet processing machine 900, open the inner cover in the direction of arrow 605, and remove the paper. Take it out.

Next, the configuration of the paper ejection mechanism unit 700 will be explained with reference to FIG. 11.

The paper ejection mechanism unit 700 includes paper receiving rollers 706.7.
08. Gate claw 712 that determines the paper feed direction. A conveyance path to the sorter 1000, feed rollers 720 and 722 placed on this conveyance path, and a paper sensor 736. It consists of a conveyance path to the tray ET, feed rollers 726 and 728 placed on this conveyance path, and a paper sensor 734, and a slit plate 7 of a rotary encoder is attached to the roller shaft 704.
30 is fixed.

When the paper is instructed to be ejected to the tray ET, the solenoid 716 remains de-energized, and the paper is transferred to the gate claw 712.
The lower curved surface of the paper is directed toward rollers 726 and 728, and these rollers send the paper in the direction of arrow 701 to reach the tray ET.

When a paper is instructed to be ejected to the sorter 1000, the solenoid 716 is energized, the gate pawl 712 rotates clockwise, and the six papers are guided toward the rollers 720 and 722 by these rollers in the direction of the arrow 703. was sent to
This leads to sorter 1000.

As explained earlier, the vertical folding mechanism unit 100 and the 90°
The paper is fed to the roller 254 of the turn mechanism unit 200 at the same speed as the paper feed speed of the copying machine 800, or slightly faster than the paper feed speed of the copying machine 800. The rollers 304 and 308 feed the paper at a faster speed than 1.
The rollers after roller 310 of the blade folding 41W unit 300 feed the paper at an even faster speed. The reason why the paper feeding speed is increased as it goes downstream in the sheet processing machine 900 is to prevent the paper from stopping in the sheet processing machine 900.
This is to reduce the number of fed sheets by immediately stopping paper feeding from the copying machine when a paper jam occurs in the sheet processing machine 900, and to widen the interval between sheets fed to the sorter 1000.

The configuration of each mechanical unit has been explained above.

13a to 13d, the operation board control unit 1
The control operation of the operation board control unit 10, that is, the control operation of the microprocessor 14 will be described with reference to these drawings showing the control operation of the microprocessor 14 of No. 0.

First, reference is made to FIG. 13a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) 14 initializes the input/output ports, registers for temporary data storage, status registers (flags), counters (program counters), timers (program timers), etc. (Step l). In the following, the word "step" will be omitted in parentheses, and only the step symbol will be shown.

After initialization, the CPU 14 reads the status.
qU. In this step, it is first checked whether there is a read flag (2), since initialization has just been completed at this point, so there is no read flag.

Proceed to step 3 and set standard data in the operation board register. Standard data.

Paper size: A4 Digit selection: Unfolded Portrait/Horizontal Orientation: Landscape Stamp position IE: om ■Publisher:
1st! 2nd total (1st publisher's seal) Drawing type: Temporary drawing (1st drawing type) Punch selection: No punch paper ejection selection Turn on the indicator light. In this state, on the operation board 12, standby (this is set at initialization),
A4. No fold y Horizontal t 011y Indicator lights indicating each of the following: No punch, 1st design, tray, and temporary drawing are lit.

FIG. 12b shows the writing position of data temporarily written to the 3-byte memory area (an area of the internal RAM of the CPU 14) allocated to the operation board register OBR.

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
Determine whether or not a signal is transmitted from 0 (5). If there is transmission, receive it, read the signal and data, and determine whether the signal is a start signal (6). If it is not a start signal, it is an end signal. 7), and if it is not an end signal, it is data, so of the input data, the data for which memory bits are assigned to the operation board register OBR is updated and written to the operation board register OBR. 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 one is.

This indicates that the copying machine 800 has given an instruction to the sheet processing 1900 regarding how to process a sheet. Although not shown in FIG. 1, the CPU 14 stores in its memory data received from the copying machine and indicating what has been written to the operation board register OBR (indicating what the written data is). When data is received from the copying machine 800 and writing to the operation board register OBR is completed and the process proceeds to step 9, or there is no input from the copying machine 800,
Proceeding from step 5 to step 9, the key input on the operation board 12 is read in this step. If the key-in is by the key switches 12a to 12e (10), refer to the copy machine 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 specification bit of the operation board register OBR is updated to the 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 85, the size designation bit is updated to data indicating A2, the B5 indicator light is turned off, and the A2 indicator light is turned off. lights up. 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 update, key switch 1
The CPU 14 performs similar operations in response to key-ins from 2c to 12h.

The reason why the input data from the copying machine 800 is given priority in this way is that the data from the copying machine 800 is more reliable than the settings made by the operation board 12. When no data is received from the copying machine (for example, when the copying machine is not connected), or when only a portion of the required data is received, the missing data is updated and set in accordance with the key input from the operation board 12. When no data is given from the copying machine and there is no key-in on the operation board 12,
The setting data is the above-mentioned standard data, which is different from the step development of the flowchart shown in Figure 1, but the start signal for the mechanism of the sheet processing machine to start operation is also received from the copying machine 800, and the start signal of the operation board 12 is received. The key switch L2i is used to key in, but if even some data is being received from the copier 800 (OB
For the copying machine input bit R=1), the key-in of the start signal by closing the switch 12i is not accepted in step 38. 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 (set the data received from the copying machine), or if you set the data in step 13 (set the key-in data), or the copying machine does not send data (5)L Maybe there is no key-in (9).

Proceeding to step 14 in FIG. 13b, the signal level of the signal receiving port from the unit 20 is referred to see whether it is ready (paper can be accepted) or not (standby: paper cannot be accepted).

If the vertical fold & 90 @ turn control unit 20 is ready in step 14 of FIG. Check whether the is ready or not.

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. Therefore, it is necessary to set l indicating that processing is possible in the ready standby bit of the operation board register OBR24). Compare the data in board register OBR and the data in previous operation board register POBH (
25), since the pre-operation board register OBR is cleared in the initialization of step 1, step 2 is used for the first time.
When the process advances to step 5, the contents of the two do not match, which means that the processing mode data transfer to each unit 20 to 60 from step 27 to be described later is not executed.

Therefore, first in step 26, the operation board register OBR is
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. 13c.

In setting the A version processing mode to the unit 20 (27) in FIG. 13c, first, the size is determined from the data of the size designation bit of the operation board register OBR (271).
.

If the size is A2, the primary is the OBR digit selection pin
(272-276), and if there is no fold, data indicating A2/longitudinal/passing mode is transmitted to unit 2o (273); and when folded in four,

Data indicating the A2/vertical folding mode is transmitted to the unit 20 (275). When folding in two, change to 2 knits 20, A
2. Send data indicating vertical/passing mode (277)
. In addition, if it is a JIS fold, data indicating A2, edge fold, JIS, and 1m fold mode is sent to the unit 20 (2
78).

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

If the size is A3, refer to the OBR length/width specification bit, and if it indicates the height (280), send A3/vertical/passing 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
Then, the A3/lateral/passing mode is transmitted (283), and in some case, the A3/90° turn mode is transmitted to the unit 20.

When the size is A4 (285),! /side finger
, refer to the constant bit 286), and if it indicates lateral (286), send -A4/lateral/passing mode to unit 20 (287). If it does not indicate the side, A4/90@turn mode is sent to the unit 288 (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 85, 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 blade folding mode (29) in FIG. 13d, in which step 29:
First, the digit selection bits of the operation board register OBR are referred to (291, 292, 294), and when there is no fold, size data is attached and a pass is sent to the unit 30 (295). In the case of 4-fold, 2-fold, and JXS-fold, use the size designation pins 1 to 1 on the operation board register ○BR.
data and digit selection bit data are sent to unit 30 (293, 296). Thus, from unit 10 to 3
0 is given a control operating mode indication and will be set in the microprocessor of unit 30.

When you finish setting the wing folding mode (29), Units 1 to 10
The CPU 14 sets the punch mode (30).

In this case, refer to the size specification bit data, digit selection bit data, and punch selection bit data of the operation board register OBR (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 85 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 unit 1O sets the stamp mode (31).

In this case, the stamp selection bit of the operation board register OBR is referenced (312), and if it is 1 indicating a stamp, the stamp selection bit, stamp position bit, issuer selection bit and Send drawing type selection bit data (313)
, if the stamp selection bit is 0, it 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 in 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 (323). 322).

After setting the paper ejection mode (32), the unit
This means that the control operation mode has been instructed to all units 20 to 60, 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. 13b, and proceeds through step 24 to step 25. Here, the data of the previous operation board register POBR is
As a result of the previous execution of step 26, the data matches the data in the operation board register OBR, so the process proceeds from step 25 to step 33.

In step 33, all indicator lights on the error 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); Returning to step 5 in FIG. 13a, the arrival of the signal from the copying machine 800 and the operation board 1
Wait for key-in number 2.

When a start signal arrives from the copying machine 800 (6), refer to the ready/standby bit of the operation board register OBR (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 units 20 to 60 sequentially transmit a start signal (37), R, and then proceed to reading the status of the following steps. Upon receiving the start signal, each of the units 20 to 60 starts driving the conveyance roller, and the paper arrives at each sensor. When the 6th sheet of paper arrives, a predetermined control operation is started.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 20 waits (
If the CPU 14 of the unit 10 reads this in step 14 of Figure F13b and proceeds to abnormality processing (15) of the unit 20, the CPU 14 of the unit 10 will proceed to the abnormality processing (15) of the unit 20. In this abnormality processing, first the operation board register OBR is The copying machine input bit is referred to (151). If it is 1, data has been received from the copying machine 800 and sheet processing has not yet started or has already started, so the copying machine 800
transmits an abnormality (standby) to (152), sets the ready/standby bit of the OBR to 0 indicating inoperability, turns off the ready indicator light of the operation board 12, and turns on the standby indicator light (153); Next, the abnormal data is received from the unit 154 (154), and if the abnormal data indicates a paper jam, the abnormal display panel 1 corresponding to the position data is displayed.
3. Turn on the indicator light above (156) - If the abnormal data indicates that it is not a paper jam.

All four indicator lights on the display panel 13 corresponding to the abnormal machine unit are turned on (157), and the first
Return to the status reading after step 5 in Figure 3a.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 30
(processing is not possible), or if the CPU 14 of the unit IO reads this in step 16 of FIG. 13b, and proceeds to the abnormality processing (17) of the unit 30. This is the same as process (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 enters a waiting period.
(processing not possible) or when the unit is on standby, the CPU 14 of the unit 10 reads this in step 13b @ step 18, and proceeds to the abnormality processing (19) of the unit 1-40. This abnormality processing (19) is described above. This is similar to the abnormality processing (15).

However, unit 20 in (15) should be read as unit 40.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 50 waits (
If the CPU 4 of the unit 10 reads this in step 20 of FIG. 13b, the process proceeds to abnormality processing (31) of the unit 50. This abnormality processing (21) is similar to the above-mentioned abnormality processing (15).

However, the unit 20 in (15) should be read as the unit 50.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 60 waits (
If the CPU 14 of the unit 10 reads this in step 22 of FIG. 13b and proceeds to the abnormality processing (23) of the unit 60, this abnormality processing (23) is the same as the above-mentioned abnormality processing. This is the same as (15).

However, the unit 20 in (15) should be read as the unit 60.

1! The operation of the longitudinal folding mechanism unit 100 and the operation of the 90 DEG turn machine groove unit 200 provided by the folding &90' turn control unit 20 have been described in their respective mechanism descriptions. I want this unit 20
Since the explanation of the control operation is redundant, it will be omitted here.

Further, the operation of the blade folding IaW unit 300 brought about by the blade spar control unit 30 is controlled by the unit 300.
It was explained in the mechanism explanation section. Therefore, the explanation of the control operation of this unit 30 will be omitted here since it will be redundant.

The control operations of the punch control unit 40 and the stamper control unit 50 will be described later.

The control operations of the vertical conveyance and paper ejection control unit 60 include driving of the single paper conveyance roller, paper jam detection, and gate claw 7.
12 positioning control, which is only ft1f, and can be easily understood by those skilled in the art from Mechanism Description 1 of the units 600 and 700, so the explanation here will be omitted.

Next, the control operation of the microprocessor of the punch control unit 40 will be explained with reference to FIGS. 14a and 14b. See also FIG.

First, reference is made to FIG. 14a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) of the unit 40 executes initialization (40).

Execute status reading (41). Note that unit 1 is initialized.
Set wait on signal line to 0.

As a result of the status reading (41), if the sensor 478 or 480 detects paper (42), it means that there is some remaining paper, so a paper jam signal is sent to the unit 10 (43), and the switch 476 (FIG. 1) is activated. Read the status of, during paper jam, steps 44-41-42-43-44-41-
..., when the switch 476 is closed, it reads whether the switch 460 is open or closed, and if it is open,
Since the cutter 452 is not at the home position shown in FIG. 8, it waits. When the switch 476 is closed while the cutter 452 is at the home position, the process proceeds to steps 44-45-46, where the pulse motor 458 is energized for forward rotation and the timer Tam is set (46). This is the time it takes for the cutter 452 to travel a distance slightly longer than the short side length of A2. When the timer Tan exceeds (47), the motor 458 is stopped (48), the motor 458 is reversely energized, and the timer Ta11 is set (50). Then, the switch 460 waits for the switch 460 to close or the timer Tan times out (51, 52), and the switch 460
When the switch 460 is closed, the cutter 452 has returned to the home position and the motor 458 is stopped (56).
If timer Tam times out without closing,
Since the return of the cutter 452 is abnormal, the energization of the motor 458 is stopped 53), and a mechanism abnormality is sent to the unit 10. 54) The unit 40 proceeds to abnormal standby processing (55).
The CPU remains in this abnormal standby state until the power is turned on again.

Now, if the switch 460 is closed and the motor 458 is stopped before the timer Ta1I times out (56
) and read the state of switch 484 (57).

If the switch 484 is closed and the punch unit is not at the home position (A4 punch position) (the initial state when the power is turned on is the A4 punch position), the pulse motor 450 is activated to set the punch unit at the home position. is reversely energized and timer Tba is set (58
). Tba is the punch unit from B5 punch position to A4
This is the time required to reach the punch position (home position).

When switch 484 is closed (59), motor 45
0 is stopped (62), and when Tba passes without the switch 484 being closed (60), fi! Because it is abnormal,
Stop the motor 450 (61).

Proceed to abnormal standby (55).

When switch 484 is closed to stop the motor (62
), proceed to status reading 41, in status reading 41 sensor 47
If paper is not detected in any of the units 8 and 480 (42), the switch 460 is closed (49), and the switch 484 is closed (57), the unit 10 is in a normal standby state, so a ready message is sent to the unit 10. Do (63).

When ready is transmitted to the unit 10 (63), the unit 10 waits for transmission (64), and if there is a transmission, it is received (65). This transmission is the setting of the punch mode (30) in FIG. 13d.

Upon receiving the signal from unit 10 (65), the 14th
Proceeding to step 66 in Figure b, it is checked whether the signal is a start signal or not. If it is not a start signal, check whether it is data or not (
67), if it is data, the received data is stored in the mode register 68).

Refer to the data contents of the mode register (69.70
), if the content is punch specification and B version, the pulse motor 450 is driven in normal rotation from the A4 punch position (home position shown in Figure 8) to the BS punch position and stopped at the BS punch position (71). . When it stops, it notifies the unit 10 that it is ready again (63), and if there is no punch instruction,
Also, when using A version punch, unit 10 is used as is.
inform the lady (63),
When a start signal is received from the unit 10, all rollers are set to the driving state and the timer Ts is set (72), and the sensor 478 detects paper.

Or wait for timer Ts to time out (73
, 74), if Ts times out without paper arriving, it is assumed that there has been some kind of trouble in the mechanical units up to the punch mechanism unit 400, that there has been a change in the state of the copying machine that does not start copying, or that paper feeding has ended. 75), and stop the roller drive.
Send standby to unit 10 76) Proceed to status reading 41.

When this process is followed, the unit 400 is in the ready state, so immediately after that, in step 63, the unit 100 is ready.
The unit 10 then sends a ready signal to the unit 10 and waits for the start signal to arrive again from the unit 10.

Now, when the start signal arrives and the sensor 478 detects paper before the timer Ts times out (73), referring to the contents of the mode register (77.78), punching is instructed and when it is the A version, the solenoid 428 is energized. and raises the register 426 to the paper stop position (79). When punching is instructed and it is the B plate, the solenoid 424 is energized and the register 422 is raised to the paper stop position (80). When punching is not instructed, the solenoid 426 and 424 are not energized.

Now, when the solenoid 426 or 424 is energized.

Wait for the sensor 480 to detect paper (81), and when it detects paper, wait for the timing when one paper comes into contact with the register 426 or 422 (82, 83° 84.85), and then energize the steel ball solenoids 418, 482. Steel balls 419,483
(86), which causes the paper to register 422
Or stop in the stopped state at 422.Next, the solenoid 438 is energized, and after the time for the punch to enter the hole 444, the energization of the solenoid 438 is cut off to punch a hole in the paper (87). All solenoids 428,424°41
8. Turn off the power to the 482 88), refer to the detection state of the sensor 480 89), and set the timer Ts when the sensor 480 changes from detecting paper to non-detecting (when the punched paper passes through the sensor 480) 72). Waiting for the next paper (7)
3).

When punching is not instructed, the process proceeds from step 77 to step 90-89-72, and while the sheets of paper arrive one after another, the rollers are continued to be driven, and the punch is energized.

Do not energize the solenoid.

Next, the control operation of the microprocessor of the stamp control unit 50 will be explained with reference to FIGS. 15a and 15b. See also Figure 9a.

Referring first to FIG. 15a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) of the unit 50 executes initialization (91) and status reading (92). Then, when the sensor 598 detects paper (9
3) Send paper jam to unit IO (94)
, and waits for the sensor 598 to enter the paper press detection state while reading the state (92).

Now, in the status reading (92), the sensor 598 detects the paper f
If not, the detection state of the sensor 536 is referred to (95). If the sensor 536 is in the light detection state, the printing tool of the stamper is not at the home position, so the pulse motor 520 is started to rotate in the normal direction. Start counting the amount (96). Then, the state and rotation amount of the sensor 536 are read (97a, 98), and when the sensor 536 becomes light-shielded, the printing tool has reached the home position, so the motor 520 is stopped, and a stop restraining current is applied to the motor 520. Turn on electricity (97b). If the rotation amount reaches one rotation without the sensor 536 being in a light shielding state, it is abnormal.
The motor 520 is stopped (99), a mechanism abnormality is sent to the unit 10 (100), and the system waits until the power is cut off (101).

Now, if the sensor 536 is blocking light, the first state refers to the state of the sensor 547 (102), and if the sensor 547 is detecting light (reflector plate 545), the second print! 541 (issuer printed side) is in the home position.

If the sensor 547 does not detect light, the publisher prints J5.
1541 by one step (103). child
1 is done as follows. First, the solenoid 555 is energized and the latch claw at the tip of the arm 553 is moved to the latch shaft 543.
advance to the base, then reverse the pulse motor 520 by a predetermined angle, first cut off the energization of the solenoid 555, then urge the pulse motor 520 to rotate forward by the predetermined angle,
Then, a stop restraining current is applied to the motor 520. As a result, the second print counterfeit 541 is rotated by 360"15=72 degrees, and its print surface is advanced by one step. The sensor 536 has returned to the light shielding state.

When this one-step printing surface feed is completed.

Increment the feed step counter by 1 and compare the count value (feed step amount) with 4 (104), 4
If it is not, the state of the sensor 547 is referred to again, and if it is light-blocked, one more printing surface feed is performed.
In this way, the printing surface is advanced step by step until the sensor 547 is blocked from light. When the sensor 547 is blocked from light, the second printing cylinder 541 is set to the home position (the first line is the printing position). Become.

Note that if the sensor 547 does not block the light even after four step feeds, it is determined that there is an abnormality in the first mechanism and the mechanism abnormality is sent to the second unit 10 (100) and the process proceeds to abnormality standby (101).

When the second printing cylinder 541 is at the home position.

Next, the home position determination of the first printing cylinder (drawing type egg side) 540 and, if there is no home position setting, are performed in the same way as the home position setting of the second printing cylinder 541 (105, 106, 107).

The first printing cylinder 540 is also at the home position.

Send ready to unit 10 (108), unit 1
It waits for the arrival of a signal from unit 10 (109), and receives the transmission from unit 10 (110).

Next, the process proceeds to steps 111 and 112 in FIG. 15b, and if the received signal is data, the data is stored in the mode register (113), and the content of this data is referenced (114).
), if a stamp is specified, compare the stamp-indicated publisher's stamp data (first to fifth publisher's stamp numbers) and the current position (first Jii line's stamp number = 1) and calculate ( 1
15) If the two do not match, the second printing cylinder 541
is driven in steps (116). This step drive l
The stamp drive operation is the same as that in step 103.

For example, if the data specifies the third printing surface, 3-1
=2, 2 steps are driven and 3 is stored in the position register. When the current position is the third printing surface (position register = 3) and the first printing surface is specified, 1-3=-2, 5-2
=3, 3 steps drive. Next, the drawing mark data (1st to 5th drawing marking numbers) and the current position (first drawing breeding egg number = 1) are compared (115), and if they do not match, the first printing Step drive the barrel 540 (11
8) This printing surface setting is also similar to the setting operation in step 116.

When the setting of the printing surface is completed, a ready signal is sent to the unit 10 (108), and the process waits for a start signal to arrive from the unit 10 (109, 110° 111).

t When a start signal is received from unit 10.

Set the roller 582 to the driving state and set the timer TS (119), and wait until the sensor 598 detects paper or the timer Ts times out (120).
, 121), if Ts times out without paper arriving, either there is some kind of trouble in the mechanical units up to the stamp mechanism unit 500, there is a change in the state of the copying machine 800 that does not start copying, or the paper feeding ends (end ), the roller drive is stopped 122), a standby command is sent to the unit 10 123), and the process proceeds to the state S reading 92. When this process is followed, the unit 500 is in the ready state, so the unit 500 is in the ready state. Immediately after, in step 108, a ready message is sent to the unit 10,
The system waits for the start signal to arrive again from the unit 10.

Now, when the start signal arrives and the sensor 598 detects paper before the timer Ts times out (120), refer to the contents of the mode register (124), and if a stamp is specified, the stamp position data is stored in the counter. Set the corresponding timing pulse number and start counting down the encoder 730 pulses by 1 (12
5), wait for the count value to become O (126)
, when the count value reaches 0, the pulse motor 520 is urged to rotate in the normal direction in synchronization with the pulses of the encoder 730, and counting of the rotation amount of the motor is started (127).

When the drive amount reaches the predetermined value PV, the printing surface has arrived just in front of the roller 572, so the solenoid 128 is energized to pull up the roller 572 (129). This starts stamping.

Thereafter, the motor 520 continues to be energized for normal rotation, and the sensor 5
When 36 is blocked from light (130), the printing tool has returned to the home position, so the motor 520 is stopped and the solenoid 57
8 is cut off, and a stop restraining current is applied to the motor 520 (131). In addition.

When a stamp is not being commanded, motor 520 is not energized and solenoid 578 is not energized.

Figure 15c shows the stamped image. Among the printing positions on paper, the position from the leading edge of the paper in the feeding direction is step 12
It is determined by the value set in the counter in step 5. The printing position in the direction perpendicular to the paper feeding direction is determined by the position of the base frame 502 in the perpendicular direction.

Note that cutters 223, 376, and 452 are driven when switches 237, 390, and 476 are closed, respectively, but these are automatically driven when a paper jam spanning between units is detected. For example, when the control unit 10 is notified of both a paper discharge section jam of the mechanism unit 100 and a paper reception section jam of the mechanism unit 200, the control unit 10 may instruct the control unit 20 to drive the cutter 223. However, when the control unit 10 is notified of both the paper ejection section jam of the mechanism unit 200 and the paper reception section jam of the mechanism unit 300, the control unit 30 is notified of the cutter 37.
6 to drive the mechanism unit 30 to the control unit 10.
When a paper discharge section jam of 0 and a paper receiving section jam of the mechanical unit 400 are both notified, the control unit 40 is instructed to drive the cutter 376. Alternatively, each of the control units 20, 30, and 40 may determine an inter-unit paper jam and independently and automatically drive the cutter.

Next, the advantages of the embodiments described above will be summarized and explained.

(1) Edge folding of paper of various sizes and orientations (3 corners)
Corner folds), vertical folds, horizontal folds, punching and stamping are performed automatically and at high speed. It is possible to continuously process a large amount of paper, eliminating the need for manual work such as folding one sheet. These processes can be set according to standards.

(2) The processing mechanism is divided into units, and each unit can be pulled out to perform jammed paper removal, inspection, repair, etc. Each unit is equipped with a grip for manual paper ejection, so
Jammed paper can be removed in unit units.

(3) It is equipped with a cutter that automatically cuts jammed paper that spans two units, making it easy to remove one sheet of paper that can prevent the jammed paper from becoming a severe jam when the unit is pulled out.

(3) Il! ! 7? In the mechanism unit 100, the conveyance path for paper that does not require vertical folding is separated from the conveyance path for paper that requires vertical folding, and a paper guide gate is arranged between the two, and paper that does not need to be vertically folded is left as is. Since paper is directly fed to the next unit, paper feeding speed can be extremely high, and the jam rate is reduced. Switching between the conveyance path for paper that does not require vertical folding and the conveyance path for paper that requires vertical folding is simple, and both the single mechanism and the paper feed control operation are simple.

(4) Paper conveyance path that does not require vertical folding (roller 04゜108
) and the vertical folding paper delivery path (! folding roller 16°118.12
0) is in the form of a horizontal character.

Subsequent seat posture processing is simple, and the vertical folding mechanism unit 100 is compact.

(5) In the vertical folding mechanism unit 100, by simply adding a movable register, it is possible to select the vertical folding of the A version and the B version. Highly versatile paper size.

(6) End face fold (corner triangular fold) with push plate 138 and fold plate 1
97, and the folded shape is more accurate than when using rollers or the like. Switching between the A version and the B version is performed only by a movable register, and paper feed control is extremely simple compared to the case where rollers or the like are used.

()) The folded plate has a paper-shaped end in a plane.

A corner of the paper is formed on the straight part of the "C" character.The straight part of the paper raises the corner of the paper, and the curved part bends one side, so the entire paper is To avoid misalignment, ensure folding in a fixed shape.

8) In the 90° turn mechanism unit 200, a plurality of rollers with different linear speeds are arranged in a direction perpendicular to the paper feeding direction, and a steel ball solenoid is arranged on top of the rollers, and the steel ball solenoid is turned on and off. Since the steel ball is pulled up from the paper and dropped onto the paper, it is possible to directly feed the paper and
The unit 200 is compact because it is not necessary to separate the direct feed path for the six papers and the 90° turn path, which allows easy switching between the ``turn'' and smooth 90'' turns. A register that can move forward and backward is placed at the paper feed opening to adjust the posture of the directly fed paper (correct misalignment) there, so that the two sheets are fed in the same posture, and the paper is then transferred to the mechanical unit. becomes accurate.

In the 90° turn mechanism unit 200 as well, the paper receiving path is shaped like a horizontal block, and vertically folded plain paper and vertically folded paper are received separately, and both are aligned and sent out to a common outlet. This simplifies the handling of paper in the mechanical unit. Since both the vertically folded non-paper feed roller and the 90'' turn roller are used to feed the paper together with a steel ball solenoid, single sheet feed selection and control can be performed easily and smoothly.

(9) In the blade folding machine groove unit 300, the folding rollers 318, 320, 322 for the first horizontal fold and the folding rollers 320, 322, 324 for the second horizontal fold 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 vertical folding rollers as the center, and the angle between the paper input conveyance path (303) and the second horizontal folding conveyance path is a small angle, and the first horizontal 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.

(10) Whether or not to make the first horizontal turn is determined by the gate pawl 324 and the solenoid 332 that drives it.

These are small features and occupy a small space. Similarly, whether or not to make a second horizontal turn is set by the gate pawl 350 and the solenoid 358 that drives it.
These are also small mechanisms.

Moreover, it occupies 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.
is pivotally attached to the axis of the roller 320, and driving the two to the transverse folding position and retracting from the transverse folding position is easy, and the control is only by turning on and off the solenoid, and only W. .

(11) The first horizontally folding conveyance path (305) and the second horizontally folding conveyance path (
307) are each equipped with movable registers and fixed registers for various paper sizes and various folds, and automatically select many types of folds of many sizes as shown in FIGS. 3a and 3b. . Since the movable register is solenoid driven, selection and setting of the register (size and fold) is easy.

(12) Arm 33 that drives gate claws 324, 350
0.354, the latch claws 348, 368 are fixed to the movable register, and when the solenoids 332, 358 are energized and the gate claws 324, 350 are driven to the non-folding setting position, the engagement The interlocks 331, 355 engage with the latch claws 348, 368, and the arms 330, 35
4 is locked by the weight of the movable register, 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 side bending and the movable register does not need to be driven, and when retracting (unlocking) the gate pawl, there is a high possibility that there is a side bend and the movable register needs to be driven, so the above-mentioned The gate pawl latch mechanism, the latch, and the release operation rationally utilize the originally required mechanical elements and the required operations.

(13) Lower guide plate of the first horizontal folding conveyance path (305)
, the tip, and the second horizontal folding conveyance path (307
) At the tip of the lower guide plate, there is a flexible member 305c,
307c (Fig. 7b) is attached, and these are
Prevents paper from being damaged and prevents paper jam on the horizontal folding roller. Also, it is useful for making the angle between the paper input conveyance path (303) and the second horizontal folding conveyance path small, and the angle between the first horizontal folding conveyance path (305) and the paper output conveyance path (309) small. ing.

(14) All the rollers in the paper input conveyance path (303) are designed to feed the paper in cooperation with the steel balls above them. There is. 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 transverse folding 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).

(15) The axes of the rollers 410, 412, and 414 are tilted, so that the paper is brought to the fixed register 460 until it reaches just below the punch rod, and the tip is placed in a movable register according to the size of the paper. can be arranged. Therefore, the punch holes are neatly arranged on a line parallel to one side of the paper, and the punch positions are accurate.

(16) In the punching mechanism unit 400, the paper is stopped by the movable register and the steel ball solenoid is energized to cut off the feeding force to the paper and punch the paper, so that holes cannot be punched while the paper is stopped. , even with high-speed paper transport settings.
Punch holes will not be torn or deformed. Punch holes are punched at positions appropriate for the paper size. paper size,
Based on the posture and the signal indicating whether punching is necessary, it is automatically determined whether or not to punch, and when punching, the punching position is automatically set.

(17) The stamp mechanism unit 500 includes polygonal printing layers 540 and 541, which are connected to a solenoid 554,
555 and the printing tool drive motor 520, there are fewer mechanical elements for updating the printing surface, making it compact.

(18) The printing layers 540 and 541 are polygonal.

Since the printing tool is installed eccentrically from the rotating shafts 510 and 528, only the printing surface set at the printing position is stamped during the rotation of the printing tool (one rotation of 510). There are no stains on the paper. Note that the printing rubber supporting side of 540° 541 for printing does not have to be a flat surface, but may be an arcuate curved surface.

(19) The stamp roller 572 can move forward and backward and is driven by a solenoid 578, and at the appropriate position the paper is pushed up slightly from the conveying surface toward the free rotation wheel, and at the retracted position it does not contact the printing surface. Therefore, even if the printing tool rotates, if the stamp roller 572 is in the retracted position,
The roller 572 is not stained with ink.

(20) The printing tool drive motor 520 is a pulse motor, and a stop restraining current is applied when the printing tool is stopped.

The stop and restraint (positioning) of the printing tool is reliable.

(21) The printing tool drive motor 520 is a pulse motor, and when stamping, the paper feed synchronous pulse (enco
- Since the printing tool is driven in synchronization with the paper pulse, the printing tool can be accurately and easily driven in synchronization with the paper.

(22) You can manually adjust the position of the base frame in the direction perpendicular to the paper feeding direction, and adjust the stamp position in this direction! ! Can be set.

The stamp position in the paper feed direction is automatically determined according to electrical signals and can be set using a switch.

(23) The ink roller 560 can be freely detached from the base frame,
Further, the stamp mechanism unit 500 is a sheet processing machine 900.
Since it can be freely pulled out from the main body, it is easy to remove dust from the ink roller 560, supply new ink to the roller 560, etc.

(24) The date at the printing position of the printing tool can be changed by rotating the manual rotary wheel 522 with the unit 500 pulled out in the manner shown in FIG. 9C. Mechanism unit 50
0 can be withdrawn freely.

This date is also relatively easy to change.

(25) The feeding direction of the processed paper can be selected.

This setting is also done electrically. Paper ejection in one of the two directions is performed by one solenoid 716 and gate pawl 712, and the mechanism and control are simple.

(26) Each of the control units is provided approximately corresponding to the mechanical unit classification, and an operation board control unit is provided, the operation board control unit is the main control unit, the other control units are the slave control units, and the paper size, posture,
Data indicating fold type, need for punching, need for stamp, stamp content, etc. is given to the operation board control unit from the shaking board and/or host such as a copying machine, and the operation board control unit determines the sheet processing mode and makes a decision. The processing mode of each slave control unit is determined based on the sheet processing mode determined, and this is sent to the slave control unit.

Therefore, the control operation of the slave control unit is relatively simple, and the slave control unit performs sheet processing control, paper jam determination and abnormality determination, and paper jam determination of the mechanical unit assigned to it.

All you have to do is stop protection in the event of an abnormality and send this to the main control unit. The overall movement of the sheet processing Ja900 and the movement of each mechanical unit are matched, allowing a quick response in the event of a problem and preventing the problem from becoming more serious.

(27) If the signals and data obtained from the settings of the host such as the copier 800 and the signals and data obtained from the settings of the operation board overlap, the i-made board control unit gives priority to the former over the latter. 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 becomes 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 operations of the host and the sheet processing machine are synchronized or coordinated.

If the host is not connected, the sheet processing machine 900 operates in response to input from the operation board, so the sheet processing machine 900 can be used alone.

(28) Based on the upper digit data such as 4-fold, 2-fold, JIS fold, etc. and paper size data, the sheet processing machine 900
Fold in two vertically, fold JIS vertically in two, and fold in two horizontally.

Since the lower fold types that need to be specified in the vertical folding mechanism unit 100 and the blade folding mechanism unit 300, such as horizontal JIS folding, are automatically determined and automatically set,
There is no need for the operation board or host to be able to set a large number of lower fold types, and the operator can easily set the processing mode. Similarly, one paper posture data and size data, as well as
Based on the upper digit data, 90° turn mechanism unit 2
Since the sheet processing machine 900 automatically determines and automatically sets whether a 90" turn is necessary, which needs to be specified at 00, the operator does not have to think about whether a 90" turn is necessary or not. There's no need.

(29) When viewed in the paper feeding direction, the paper feeding speed of the upstream mechanical unit is relatively low, and the paper feeding speed increases as the downstream mechanical unit approaches. The most upstream mechanical unit 100 has a speed comparable to the scheduled host paper delivery speed. Since the speed is set in this way, the sheet processing machine 9
00, the number of sheets existing at one time is as small as possible, and the number of sheets remaining in the event of a paper jam is reduced. Also,
In the event of a paper jam, the host is notified quickly and the amount of unnecessary paper sent is reduced. In addition, idle time for feeding paper to downstream equipment such as a sorter becomes longer, and the operating margin of the equipment becomes larger.
