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 10O.

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 specified.

The solenoid 114 is not energized and the paper entry gate 112 is placed at the position shown by the solid line. In this state, the paper sent directly below the one-sheet sensor 174 is received by the rollers 104 and 108, but hits the lower curved surface of the claw 112, is bent downward, and goes straight to the unit 200. When vertical folding is instructed, when the sensor 174 detects paper, the solenoid 114 is energized and the tip of the claw 112 is aligned with the lower roller shaft 1.
06 direction (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
It is in pressure contact with 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.
8 to feed the scratched paper to the register 78 or 126 through the upper surface of the claw 112. After the leading edge of the paper is placed against register 78 or 126, solenoid 124 is de-energized and the paper is sandwiched between vertical folding rollers 116 and 118. In this state, the paper is sent toward the register 154 or 156 by these rollers 116 and 118, and when one side of the paper hits the register 154 or 156, the paper bends when it passes between the rollers 116 and 118, and this bending Roller 118-
It is caught between 120 and folded in two vertically, and the roller 11
8, 120 (a slit-shaped opening parallel to the axis of the vertical folding roller) to the unit 200. In order to prevent the rotation of rollers 166 and 1.62 from providing resistance to the movement of the paper during such vertical folding, roller 1 is
A steel ball 169 is placed on the roller 166, and a steel ball solenoid 164 is opposed to 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, the rotation of the roller 116 drives the paper in that direction. When the paper moves in a direction perpendicular to the axis of the vertical folding roller 116 (vertical folding in two), the steel balls 169 rotate as the paper moves, so they do not interfere with the paper movement.

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

reduce frictional resistance.

The folded plate 197 is fixed to a carriage 198, and this carriage 198 is moved in the direction of the arrow (
The roller 116 is guided so as to be able to reciprocate in the axial direction of the roller 116. A link arm 196 is pivotally connected to the carriage 198, and another link arm pivotally connected to this link arm is fixed to the output shaft of the half-rotation clutch 136. A gear fixed to the input shaft of the half-rotation clutch 136 is engaged with a drive power system (not shown) of the unit 100. The half-rotation clutch 136 clockwise rotates the link arm 196 when energized. When the current is cut off, the link arm 196 is rotated half a turn counterclockwise to drive the carriage 199 (that is, the folded plate 197) to the right.
) to the left.

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 a tip 195 of the arm 146 projects into the path of the carriage 198. The U-shaped arm 140 includes a roller 152.
The roller 152 is in contact with the rotating arm 148
It is pivoted to one end of the . A plunger 150 of a solenoid 150 is coupled to the other end of the rotating arm 148 . In the state shown in FIG. 5a (standby state), the roller 152
The pressure of the U-shaped arm 140 is loose. The push plate 138 has the U-shaped arm 140 fixed to the U-shaped arm 140 in a dogleg shape by a spring 145 (left pull) and a spring 144 (upward pull).
It's lifted upwards. In this state, the roller 116-11
The paper fed between the folding plates 197 and the pushing plate 138 passes through the space between the folding plates 197 and the pushing plates 138. When the solenoid 150 is energized.

Arm 148 rotates counterclockwise, and roller 152 strongly presses arm 140. This allows the U-shaped arm 1
40 rotates counterclockwise, and the entire push plate 138
97 and presses the paper downward. When the half-rotation clutch 136 is energized in this state, the folded plate 197
moves to the right and bends the paper as it goes over the push plate (138).When the fold plate 197 moves to the right to some extent, the carriage 198 moves to the tip 1 of the arm 146.
Push 95 to the right.

As a result, the punch 138 also moves to the right. When the U-shaped arm 140 comes off the roller 152 to the right, the roller 152 prevents the U-shaped arm 140 from returning to the left. When the half-rotation clutch 136 is de-energized in this state, the folded plate 197 returns to the standby position shown in FIG. 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.
As a result, the push plate 138 moves upward and to the left by the force of the spring 145, 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 abbreviated shape to prevent the five sheets from escaping. When A2 paper is positioned with the register 178 and B3 paper is positioned with the register 126, the 1st corner of 1 paper PR (double-dashed line) is the 5th 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 vapor guide plate (not shown) by a press plate 138. When the half-rotation clutch 136 is energized, the folding plate 197 moves to the right as shown in FIG. 5f, folds the corner of one sheet, and reaches above the push plate and the paper above it. As the folding plate 197 advances 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 energization of the solenoid 150 is cut off.

The push plate 138 is moved from the position shown in FIG. 5g to the spring 146.
Return to the standby position (Fig. 5e) with force. At this time, the push plate 138 rises upward due to the action of the spring 144, and the paper PR
Do not touch the folded corner pieces.

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

) has been installed.

Each solenoid (160AJ, 160BJ: not shown) is used to selectively advance into the paper transport path, but since it would complicate the drawing, illustration is omitted in FIG. 5a.

In this vertical folding mechanism unit 100, the roller 108 is connected to the main power system (not shown) of the unit, and 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 a start signal and 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 operates in A2/4-fold mode, A2/JIS fold mode, B3/4-fold mode, and B

Next, referring to FIG. 6a, the 90° turn mechanism unit 2 is
The configuration of 00 will be explained.

In the unit 200, one paper conveyance system includes a vertical origami paper introduction system,
It consists of a paper introduction system without vertical folding, a 9-sheet feeding system with edge alignment feeding, a 90° turn feeding system, and a delivery system. The general division of paper transport elements is shown below.

216 and rollers 286, 288, 290, 292,
294°, 296° rollers 292, 294 and 296 are pivotally connected to a shaft 298, and a solenoid 2 is connected to this shaft 298 via an arm.
99 plungers are connected. Solenoid 299
When energized, rollers 292, 294 and 296 are pressed against rollers 286, 288 and 290, respectively.

Rollers 286, 288 and 290 move the paper to register 2.
62,264. Edge alignment feed system: rollers 272, 276° 280, 284.
Steel ball solenoid 274.278.295. 291. Rollers 242, 254. Steel ball solenoids 244, 256 Steel ball solenoids 274, 278, 295 and 291 are de-energized and steel balls 275, 279, 293 and 289 press the paper against rollers 272, 276, 280 and 284 with their own weight, so the paper are registers 262, 26
Driven towards 4.

When the edge of the paper comes into contact with the registers 262, 264,
.

This causes the paper to bend slightly, but the pushing edge provided by the steel ball is small and the steel ball itself no longer applies any driving force to the paper.

This curve will not be large. Steel ball solenoid 274°2
When electricity is applied to 78.295 and 291, the paper becomes free and the paper returns to a smooth state due to the recoil force of one bend.

In this state, the edge of the paper is in register 262 and/or 264.

Paper introduction system without vertical folding: A slit plate 299 of a rotary encoder is connected to the rollers 204 and 208° drive roller 208.

If a paper jam occurs with paper being pinched between the feed rollers 104 and 108 of the unit 10 and between the rollers 204 and 208 of the unit 200, the jammed paper will is torn.

It becomes difficult to remove it.

Therefore, a cutter 223 is placed upstream of the rollers 204 and 203.
is installed. The cutter 223 is fixed to a carriage, and the carriage is guided by a guide bar 225 so as to be able to reciprocate in parallel with the roller shaft 202. 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 normally, the cutter 223 moves backward from the position shown in FIG. 6a (front standby position) a distance slightly longer than the length of the A2 short side, thereby cutting the jammed paper. When the motor 229 reaches this distance, the motor 229 is stopped once, and then the motor 229 is reversely energized until the switch 231 is closed and returns to the standby position shown in the figure.

Paper passing system: Rollers 218, 222, 226, 230°24
2.250,254.11 ball solenoid 220°224
．． The axes 246 and 258 of the 228, 232, 244, and 252° 0-rails 242 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 shaft 246
and 258 are connected 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 the 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 the paper passing (sheet ejection) drive is started, the entire leading edge of the paper reaches the register 266. solenoid 2
By energizing 70 and retracting the register 266, the posture of one sheet is adjusted.

906 turn system: rollers 238, 234. fR ball solenoids 236, 240 The roller 238 rotates at the same linear speed as the paper passing roller, but the roller 234 rotates at a linear speed that is 1/3.43 of the linear speed of the roller 238. Note that all roller shafts other than the shaft of roller 240 in this 90@turn feed system rotate at the same speed.

Since the linear speed of the roller 234 is slow, the steel ball solenoid 236
．． When the steel balls 237 and 241 are on the paper with no current flowing through the steel balls 240, a rotational force, that is, a clockwise rotational force is applied to the paper.

1 inch interval m rollers 211, 207 On the roller shaft of the drive roller 211, there is a grip 21 for hand rotation.

The main power system of the unit 200 includes a shaft 206 of a drive roller 208 for introducing paper without vertical folding. Drive rollers 216, 286 of the vertical origami introduction system. Edge alignment feed system roller shaft and 90
The shafts 3 of the rollers 238 of the turn feed system are connected in such a way that they all have the same speed (same speed as the roller shaft 106 of the unit 100, and the same speed as the feeding speed of the copying machine 800 for the unit 100). , the shaft of the roller 234 of the 90° turn feed system is coupled to the main power system of the unit 200 via a reduction gear. The shaft 213 of the drive roller 211 of the feed-out system is connected to the main power system of the unit 200 through a gear with a relatively small number of teeth.
It rotates at a faster speed than the rotation speed of 06 etc. Therefore, when the paper reaches the rollers 207, 211, it is delivered to the unit 300 at high speed while being pulled by these rollers. At this point, the paper is transferred to roller 2o8°204
Since the paper is pressed against the rollers 250, 242, 254, etc. by the steel balls, 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 rerollers 204-208.

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

When the count value reaches the predetermined value assigned to A3.

The steel ball solenoids 240 and 236 for the 90° turn 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 266 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 solenoid 236, 234 is energized and the 6 count value is set so that no rotational force is applied to the paper. When becomes the fourth value, 1wI ball solenoid 278, 29

The entire side is driven to a position where it abuts registers 262 and 264. When the count value reaches the fifth value.

The steel ball solenoids 278 and 295 are energized and the roller 276
．． 280 is released. When the count value reaches the sixth value, the paper should be in close contact with the registers 266 and 264, as shown by the three-dot chain line in Fig. 6b, so the steel ball solenoids 244, 256
, 291 is energized, the solenoid 270 is de-energized, and the paper is sent to the rollers 207, 211. Paper is the sensor 233
After passing through the register 226, the encoder 297 starts counting pulses, and when the count value reaches a value corresponding to the timing when the trailing edge of the paper passes the register 226, the sensors 217 and 219
And on the condition that 221 does not detect paper, all electricity to the steel ball solenoid is cut off. The control timing for the 90@ turn of A3 explained above is shown in FIG. 6d.

(2) A4/vertical mode--The operation of the unit 200 is similar to the 90° turn operation of the A3 described above.

However, because the size is different, the control timing is different.
4. The posture of the paper during a 90° turn in portrait mode is 6c.
The control timing is shown in FIG. 6e.

(3) The operations of B3 horizontal 90° turn and B5 vertical 90@turn are also the same as in (1) above. However, since the sizes are different, the control timing is different.

In this case, one sheet of paper is used for register 266 and register 262.
and 264, and other sizes to be sent to the unit 300 in a position that perfectly aligns with 264.

The same applies to the control of the transparent mode of the posture. however.

The control timing differs depending on the size and paper input orientation.

(5) A2/vertical/fourfold or JIS folding mode --- In this mode, the vertically folded paper is folded from the unit 100 to the roller 216.
- It is sent between 212 and 212. In this mode.

When the sensor 174 of the unit 100 detects paper, the encoder 297 starts counting the generated pulses, and when the sensor 174 returns to detect paper failure, the steel ball solenoids 278, 295, 274, 291, 220, 228 ，

If 7 is assumed to be instantaneous, the cutter 223 moves backwards a distance slightly longer than the short side length of the A2 sheet, cuts the jammed paper, returns to the front, and when the switch 231 returns to the closed position (the position shown in Figure 6a). ) to stop. When the jammed paper straddles the vertical folding rollers of the unit 100 and the rollers 216 and 212 of the unit 200, the units 100 and/or 200 may be pulled out as they are. At this time, the jammed paper will be pulled out from one unit by pulling out the units. If you want to be safe in advance, turn the grip 180 of the unit 100 or the grip 215 of the unit 200 sufficiently before pulling out the unit. By turning the grip 180, the rollers of the unit 100 rotate to feed out the paper, and by turning the grip 215 of the unit 200, the rollers of the unit 200 rotate and pull out the paper.

Next, the configuration of the blade folding mechanism unit 300 will be explained with reference to FIG. 7a.

The main elements of the blade folding mechanism unit 300 are a horizontal folding opening l;

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,
It has already passed 30g. A sensor 386 detects paper on the incoming paper transport path.

A 1-rotation arm 328 is pivotally attached to the shaft 326 of the horizontal folding roller 318, and a drive arm is attached to a free pin erected on the 0-rotation arm 328 to which the first gate pawl 324 is fixed. 330 is engaged. The drive arm 330 is pivotally connected to a shaft 334, and the drive arm 330 is

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 one-rotation 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.

A rotating arm 352 is pivotally attached to the axis of the horizontal folding roller 320, and a second gate pawl 350 is attached to the rotating arm 352.

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, the rotating arm 352 rotates clockwise, and the first gate pawl 350 rotates between the transverse 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 that determines the first fold position of the 84・JIS fold.

At this time, when the leading edge of the paper hits the register (336, 338, 340 or 342) on the first folding conveyance path, the paper starts to bend on the exit side of the rollers 318 and 320, and when the amount of bending becomes large enough, the paper starts to bend. is doubled up and caught between 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

Plungers 385 (not shown) t 370 and 3625 (not shown) are connected and are retracted from the paper transport path when the solenoids are de-energized. When the solenoid is energized, it advances into the paper conveyance path and stops the movement of one sheet of paper.

The second gate pawl 350 is at the transparent guide position i! (Roller 320
and 324 (opposed to the rollers 322), the paper to be sent out toward the second folding conveyance path by the transverse folding rollers 320 and 322 is held by the second gate claw 350 between the transverse folding rollers 322 and 324. When the second gate pawl 350 is retracted from the pass-through guide position, the paper is guided toward the second folding conveyance path by the horizontal folding rollers 320 and 322. Sent out. At this time, the leading edge of the paper is placed in the register (3) on the second fold conveyance path.
58, 360, 362 or 364), the paper begins to bend on the exit side of rollers 320 and 322, and when the amount of bending increases to a certain extent, the paper doubles and passes through roller 32.
It is caught in 2 and 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.

Upper and lower paper guide plates 305a on the first folding conveyance path.

The gap between 305b (Fig. 7b) is approximately 3 mm,
As shown in FIG. 7b, a flexible member 305C such as a polyester film is attached to the tip of the lower paper guide plate 305b. Similarly, the gap between the upper and lower paper guide plates 307a and 307b of the second folding conveyance path is approximately 3III11.
A flexible member 307C is attached to the tip of the lower paper guide plate 307b. As shown in FIG. 7c, by the first transverse folding roller 318 and the second transverse folding roller 320,

The leading edge of a sheet hits the lower paper guide plate 305b when it is fed into the first folding conveyance path, but as shown by the dotted line in FIG.
There is a possibility of collision with the tip of 05b. 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 horizontal folding roller 320 and the third horizontal folding roller 322 have caught up the slack in 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
, 105b can be made smaller. 7th
As shown in Figure e, the guide plates 105a, 105b and the second. By setting the angles with the center lines of the third transverse folding rollers 320 and 322 close to a right angle, the paper can be folded into the second transverse folding roller. After being held in the third horizontal folding rollers 320, 322, the paper is less likely to be scratched, and the tip of the lower paper guide plate 105b can be extended toward the horizontal folding rollers, which increases the margin for paper curling. You can make it thicker. However, when the arrangement is as shown in FIG. 7e, the guide plate 105a is not aligned with the paper input conveyance path.

Since the angle of 105b is steep, more space is required. In this embodiment, since the flexible member 305c is provided,

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 30 of a rotary encoder is fixed to the roller shaft 704.

When ejecting paper to tray ET is instructed.

Solenoid 716 remains de-energized, and one sheet of paper is directed toward rollers 726 and 728 by the lower curved surface of gate pawl 712, and is fed by these rollers in the direction of arrow 701 to reach tray ET. When a paper is instructed to be ejected to the sorter 1000, the solenoid 716 is energized and the gate pawl 712 rotates clockwise to guide the paper toward the rollers 720 and 722. sent to.

The sorter reaches 1ooo.

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 a speed similar to or slightly faster than the paper feed speed of the copying machine 800, but the paper is fed to the feed roller 211 of the 900 turn unit 200 and the next blade new mechanism unit. The rollers 304 and 308 of 300 feed the paper at a faster speed 1
The rollers after roller 310 of the blade folding mechanism unit 300 feed the paper at an even faster speed. In this way, the sheet processing machine 9
The reason why the paper feed speed is made faster as it goes downstream in the sheet processing machine 900 is to prevent paper from stopping in the sheet processing machine 900.If a paper jam occurs in the sheet processing machine 900, the paper feeding speed from the copying machine is immediately stopped. This is to reduce the number of sheets fed by stopping the feeder, and to widen the interval between feeding sheets to the sorter 1000.

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 board, registers for temporary data storage, status registers (flags), counters (program counters), timers (program timers), etc. (Step 1). 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.
＾Uh. In this step, first check whether there is a read flag (2). At this point, since initialization has just been completed, there is no read flag, so proceed to step 3 and set standard data in the operation board register. .

Standard data is: Paper size: A4 Digit selection: Unfolded Portrait/Horizontal orientation: Landscape Stamp rank 1! :On+■Publisher: 1st design (1st publisher's seal) Drawing type: Temporary drawing (1st drawing type) Punch selection: No punch paper ejection selection to turn on the data compatible indicator light. In this state, on the operation board 12, standby (this is set at initialization),
A4. Indicator lights indicating each of folded, horizontal, Omm, no punch, first design, tray, and tentative design 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.
Determine whether a signal is being transmitted from 0 (5)
, When there is a transmission, it receives the signal and reads the signal and data, and determines whether the signal is a start signal or not (6). If it is not a start signal, it determines whether it is an end signal or not. 7) If it is not an end signal, it reads the data. Therefore, in the input data,
Data to which memory bits are assigned to the operation board register OBR is updated and written to the operation board register OBR. When such an update is written, the bit indicated as the copier input bit in the operation board register OBR is set to 1.
Write. This 1 indicates that the copy Ia 800 has given an instruction to the sheet processing machine 900 regarding sheet processing.
Reference numeral 14 stores in memory the data received from the copying machine and indicating what has been written to the operation board register OBR (indicating what the 8 written data is). Copy *a
If you receive data from OO and finish writing to the operation board register ○BR and proceed to step 9, or if there is no input from the copying machine 800 and you proceed from step 5 to step 9, the operation board Read the 12 key-ins. If the key-in is from the key switches 12a to 128 (10), the copier input bit is referred to, and if it is not 1 (no data has been received from the copier yet), (
11) Update the contents of the operation register according to the key-in, and turn on the indicator light on the operation board.

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 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, size instruction key switch 1
Each time 2a is closed, the lighting of one indicator light moves from the upper side to the lower side in Fig. 12a, and at the same time, the data in the size designation bit of the operation board register OBR changes to the data indicating the size indicated by the lit indicator light. Updated. 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 12
The CPU 14 performs similar operations in response to key-ins from c to 12h.

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 12. 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 standard data mentioned above.Although the step development in the flowchart shown in the figure is different, the mechanism of the sheet processing machine is A start signal for starting and starting the operation is also received from the copying machine 800, and the start key switch 12i on the operation board 12 is keyed in. (Copier input bit of OBR = 1
), the start signal is keyed in by closing the switch 12i.

In step 38, the receiver is not attached. 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 (setting the data received from the copying machine), or if you set the data in step 13 (setting the key-in data), or the data is not sent from the copying machine (5) t , and 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. 13b, it is checked in step 16 whether the unit 30 is ready. 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 board 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). It should be noted that since the previous operation board register OBR is cleared in the initialization of 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. 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, next refer to the digit selection bits of the OBR (272 to 276), which is unsigned.
and transmits data indicating the A2/vertical/passing mode to unit 20 (273).When folding in four, unit 2
Send data indicating A2/vertical folding mode to 0 (27
5). When folding in half, data indicating A2, vertical, and passing mode is sent to the unit 20 (277), and JI
If it is an S-fold, the unit 20 will have A2/end face fold/JIS
Data indicating the vertical folding mode is transmitted (278).

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 vertical/horizontal designation bit of the OBR, and if it indicates vertical (280), transmit 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), refer to the height/width specification bit (286), which indicates the width.

If so (286), the A4/lateral/passing mode is transmitted to the unit 20 (287), and if it does not indicate the horizontal, the A4/90' turn mode is transmitted 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 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 blade folding mode (29) in FIG. 13d. In this step 29,
First, the digit selection bits of the operation board register OBR are referred to (291, 292, 294). If there is no fold, size data is attached and the passage is transmitted to the unit 30 (295). In the case of 4-fold, 2-fold, and JIS fold, the data of the size designation bit and the data of the digit selection bit of the operation board register OBR are transmitted to the unit 3o (293, 296). That's all for units 10 to 30.
A control operation mode instruction is given to the unit 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, digit selection bit data, and punch selection bit data of the operation board register OBR (301 to 306, 3
08, 309), and when the final size is A4 and punched, the A4/punch mode is sent to the unit 40 (307).

When the final size is B5 and there is a punch, the B5/punch mode is sent to the unit 40 (310), and in other cases, the non-bunch mode is sent to the unit 40.

After completing the punch mode setting (30), Units 1-10
The CPU 14 sets the stamp mode (31).

In this case, the stamp selection bit of the operating board register OBR is referenced (312), and if it is 1 indicating a stamp, the unit 50 is informed of the stamp selection bit of OBR, the stamp position bit, 9! Send data of line origin selection bit and drawing type selection bit (313
), if the stamp selection bit is 0, the unit 50
Send a non-stamp signal to.

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), unit f
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 C:PU 14 of the unit 10 then returns to step 24 in FIG. 13b, and proceeds through step 24 to step 25. Here, the data in the previous operation board register POBR matches the data in the operation board register ○BH due to the execution of the previous step 26, so the process advances from step 25 to step 33.

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 number 2.

When the start signal arrives from the copy aaoo (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 start signals are sequentially transmitted (37).

The process then proceeds to read the status of the next step. unit 2
When each of 0 to 60 receives a start signal, it starts driving the conveying 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. 13b 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, the data has been received from the copying machine 800 and sheet processing has not started or has already started, so the copying machine 800
An abnormality (standby) is transmitted to the controller (152), and the ready/standby bit of the OBR is set to 0 indicating that the operation is disabled, the ready indicator light on the operation board 12 is turned off, and the standby indicator light is turned on (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.
Turn on the indicator light above 3 (156).

When the abnormal data indicates that the paper jam is not a paper jam, all indicator lights associated with the abnormal mechanism unit on the display panel 13 are turned on (157). Then, the process returns to the state reading after step 5 in FIG. 13a.

Before or after the control unit 10 gives the start signal to the units 20 to 6o, the unit 30 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 16 of FIG. 13b and proceeds to abnormality processing (17) of the unit 30. This abnormality processing (17) is similar to the above-mentioned abnormality processing (15).

However, unit 2o in (15) is read as unit 3o.

Before or after the control unit 10 gives the start signal to the units 20 to 6o, the unit 40 waits (
If the CPU 14 of the unit 10 reads this in step 18 of FIG. 13b and proceeds to the abnormality processing (19) of the unit 40, this abnormality processing (19) is the same as the above-mentioned abnormality processing. This is the same as (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 14 of the unit 10 reads this in step 20 of FIG. 13b and 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 executes the abnormality processing (23) of the unit 10,
This abnormality processing (23) is the same as the above-mentioned abnormality processing (15).
).

However, unit 20 in (15) is read as unit 6o.

The operation of the longitudinal folding mechanism unit 100 and the operation of the 90'' turn mechanism unit 200 provided by the longitudinal folding &90'' turn control unit 20 have been described in their respective mechanism description sections. Therefore, the explanation of the control operation of this unit 20 is as follows.

Since it is redundant, it will be omitted here.

Further, the operation of the blade folding machine groove unit 300 brought about by the blade folding control unit 30 has been explained in the mechanical description of the unit 300. Therefore, this unit 3
Since the explanation of the control operation of 0 is redundant, it will be omitted here.

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, it is simple, and unit 6
Those skilled in the art can easily understand from the mechanism explanations of 00 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) and status reading (41)6.In addition, during initialization, the microprocessor (hereinafter simply referred to as CPU) of the unit 40 waits on the signal line to the unit 10. Set.

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. While there is a paper jam, steps 44-41-42-43-44-41-
I've been thinking... 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 normal rotation and the timer Tan is set (46), TaI.
I+ 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 T mechanism exceeds (47), the motor 458 is stopped (48), the motor 458 is reversely energized and the timer Tan+ is set (50), and the switch 460 is closed or the timer Ta+ is set.
It waits for timeout of n (51, 52), and when the switch 460 is closed, the cutter 452 has returned to its home position, so the motor 458 is stopped (56). If the timer TaII+ times out without the switch 460 being closed, the return of the cutter 452 is abnormal, so the energization of the motor 458 is stopped (53) and a mechanism abnormality is sent to the unit 10 (54) Abnormal standby processing (55) ).

The CPU of the unit 40 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 Tan times out (56)
, reads 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 when the punch unit moves 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). If Tba passes without the switch 484 being closed (60), there is a mechanical abnormality, so the motor 450 is stopped (61) and the process goes to abnormality standby (55).

When switch 484 is closed to stop the motor (62
), proceed to status reading 41. In the status reading 41, the 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 I switch 484 is closed (57), it is in a normal standby state and a ready message is sent to the unit 10. Do (63).

After transmitting ready to unit 10 (63), it waits for transmission from unit 10 (64). If the transmission power is τ, it is received (65). This transmission is the punch mode setting (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 power is a 1 start signal or not. The start signal is 1 and it is checked whether it is data (67), and 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 85 punch position and stopped at the B5 punch position. 71), unit 10 when stopped
The lady is notified again (63). No punch instructions 1
In this case, as well as in the case of an A-version punch, the unit 10 is immediately notified of ready (63).
When the start signal is received from the j unit 10, all the rollers are set to the driving state, the timer Ts is set L (72), and the process waits until the sensor 478 detects paper or the timer Ts times out (73, 7
4) 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 prevents it from starting copying, or that paper feeding has ended. Then, the roller drive is stopped (75), and a standby command is sent to the unit 10 (76), and the process proceeds to the status reading step (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, it waits for the sensor 480 to detect paper (81), and when it detects paper, waits for the timing when the paper comes into contact with the register 426 or 422 (82, 83° 84.85). , the steel ball solenoids 418 and 482 are energized to pull up the steel balls 419 and 483 (86), thereby stopping the paper in the state where it is stopped at the register 422 or 422.Next, the solenoid 438 is energized and the punch rod After the time for the paper to enter the hole 444, the solenoid 438 is de-energized and a hole is made in the paper (87). Next, all solenoids 428, 424° 418.
When the sensor 480 changes from paper detection to non-detection (when the punched paper passes through the sensor 480), set the timer Ts 72), and then refer to the detection state of the sensor 480 (89). Waiting for the arrival of paper (73)
.

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 vapor jam to unit 10 (94)
, and waits until the sensor 598 enters the paper defect detection state after reading the state (92).

Now, during the status reading (92), the sensor 598 detects the paper.
If not, the detection state of the sensor 536 is referred to (95). When 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 starts to be energized for normal rotation and starts counting the amount of rotation (96). Then, the state and rotation amount of the sensor 536 are read (97a, 9B), 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 (97 b). If the rotation amount reaches one rotation without the sensor 536 being in a light shielding state, it is abnormal, so stop the motor 520 (99), send a mechanism abnormality to the unit 10 (100), and wait until the power is cut off (t oB.

Now, if the sensor 536 is shielded from light, then the state of the sensor 547 is referred to (102). If the sensor 547 detects light (reflector plate 545), the second printing cylinder 541 (publisher printing surface) returns to the home page. in position.

If the sensor 547 does not detect light, the publisher's stamp
.

The character eraser 541 is advanced by one step (103). Do this like this: First, the solenoid 555 is energized, the latch claw at the tip of the arm 553 is advanced to the base of the launch wheel 543, the pulse motor 520 is reversed by a predetermined angle, the solenoid 555 is de-energized, and then the pulse motor 520 is reversed by a predetermined angle. The motor 520 is urged to rotate forward by the predetermined angle, and then a stop restraining current is applied to the motor 520. As a result, the second printing cylinder 541 rotates 360@15=72', and its printing surface is advanced by one step. Sensor 536 has returned to its light-blocking state.

When this one-step printing surface feed is completed.

Increment the feed step counter by 1.

Compare the count value (feed restep amount) with 4 (104
). If it is not 4, the state of the sensor 547 is referred to again, and if it is light-shielded, one more printing surface feed is performed. In this way, the printing surface is advanced every step until the sensor 547 is blocked from light. When the sensor 547 is blocked from light, the second printing cylinder 541 is moved to the home position (the first
i! This means that the line origin is set to the print position).

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/character surface) 540 is performed, and if there is no home position setting of the second printing cylinder 541, the home position setting is performed in the same way as the home position setting of the second printing cylinder 541 (10
5,106,107).

When the first print 15i540 is also in the home position, a ready message is sent to the unit 10 (108), and the unit 10
It waits for the arrival of a signal from the unit 10 (109), and receives the transmission from the 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 specified publisher stamp data (numbers of the first to fifth publisher stamps) with the current position (number of the first publisher stamp = 1). 115)
, and if they do not match, the second printing system 541 is driven in steps (116). The step drive operation of this step drive is the same as that in step 103.

For example, if the data specifies the third printing surface.

With 3-1=2, drive 2 steps and store 3 in the position register. The current position is the third printing surface (position register = 3)
), when the first printing surface is specified, 1-3=-2,
5-2=3, driving in 3 steps. Next, the drawing egg data (the numbers of the first to fifth drawing seed marks) and the current position (the number of the first drawing eggs = 1) are compared (115), and if the four data do not match, the first The printing barrel 40 is driven in steps (11g). 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).

Upon receiving the start signal from unit 10, i
The roller 582 is set to the driving state and the timer Ts is set (119), and the process waits until the sensor 598 detects paper or the timer Ts times out (120, 121). 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 stamp mechanism unit 500, that there has been a change in the state of the copying machine 800 that does not start copying, or that the paper feeding has ended. Look at it,
The drive of the roller is stopped 122), a standby command is sent to the unit IO 123), and the process advances to status reading 92. When this process is followed, the unit 500 is in the ready state, so immediately after that, in step 108, the unit 500 transmits a ready signal to the unit 10, and waits for the start signal to arrive from the unit 10 again.

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 number of timing pulses and start counting down by 1 for the encoder 730 pulses (125
), 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). Note that when the stamp is not instructed, the motor 520 is not energized and the solenoid 57 is not energized.
8 is also not energized.

Figure 15c shows the stamped image. Among the printing positions on paper, the position of the leading edge of one 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 discharge section jam of the mechanism unit 200 and the paper reception section jam of the VIk'm unit 300, the control unit 30 is instructed to drive the cutter 376, and the control unit 10 is notified of the paper discharge section jam of the mechanism unit 300. When both a jam in the ejecting section and a jam in the paper receiving section of the mechanism unit 400 are notified, the control unit 40
The cutter 376 is instructed to be driven. or,
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 process large amounts of paper continuously. This eliminates the need for manual work such as paper folding. 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 spanning two units, and can prevent the jammed paper from becoming a severe jam due to unit drawer. Paper removal is easy.

(3) In the vertical folding mechanism unit 100, vertical folding is not possible.
The transport path for paper that needs to be folded is separated from the transport path for paper that needs to be vertically folded, and a paper guide gate is placed between the two, and paper that does not need to be folded vertically is sent directly to the next unit, thereby reducing the paper feeding speed. can be made extremely high, and the jam rate is reduced. Switching between a paper conveyance path that does not require longitudinal folding and a paper conveyance path that requires longitudinal folding is simple, and both the mechanism and paper feed control operation are simple.

(4) Paper conveyance path that does not require vertical folding (roller 04゜108
), and a vertical folding paper delivery path (vertical folding roller 16°118.12
0) is in a horizontal-chocho shape, the subsequent seat posture processing is easy, and the vertical folding mechanism unit 100 is made compact.

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

(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 feeding control is extremely simple compared to the case where rollers or the like are used.

(7) The folded plate has a paper edge in the shape of a "C" on a plane, and a corner of one sheet of paper is formed on the straight part of the "C" character.The straight part of the character forms a corner of the paper. Since it is shaped so that one side of the paper is bent by the curved part, it is difficult for the paper to shift as a whole, and it also ensures that the paper is folded 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. , Since the steel ball is pulled up from the paper and dropped onto the paper, it is possible to directly feed the paper and
It is easy to switch between ``turns'' and 90'' turns are performed smoothly. There is no need to separate the direct paper feed path and the 90° turn path, and by arranging a register that can advance and retreat at the single paper feed port where the unit 200 is compact, the direct feed paper can also be adjusted there ( Since the misalignment is corrected, the paper is fed out in the correct orientation, and the paper is then delivered to the mechanical unit accurately.

In the case of the 90'' turn machine groove unit 200, the paper receiving path is shaped like a horizontal strip, and vertically folded paper with no strings and vertically folded paper are received separately, and both are arranged in the same position and sent out to a common outlet. This simplifies paper handling in the subsequent mechanical unit.Since both the longitudinal folding cordless feed roller and the 90'' turn roller are used together with a steel ball solenoid to feed the paper, single paper feed selection and control are simple and easy. done smoothly.

(9) In the blade folding mechanism unit 300, the folding rollers 318, 320, 322 for the first horizontal folding 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 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, and these are only 4i! structure, and it occupies a small space. Similarly, whether or not to make a second horizontal turn is determined by the gate claw 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.

(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) The tip of the lower guide plate of the first horizontally folding conveyance path (305) and the bottom of the second horizontally folding conveyance path (307) 1
At the tip of the guide plate, flexible members 305c, 30
7c (Fig. 7b) is attached, which prevents the paper from being damaged and prevents the paper from jamming on the transverse 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, 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 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 one sheet of paper is brought to the fixed register 460 until it reaches just below the punch tip, and the tip is adjusted to a movable register according to the paper size. 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 haunch 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 can be punched while the paper is stopped. Even with high-speed paper transport settings, the punched holes will not tear or deform. Punch holes are punched at positions appropriate for the paper size. Based on the paper size, posture, and signal indicating whether punching is necessary, it is automatically determined whether or not to punch, and when punching is to be performed, the punching position is automatically set.

(17) The stamp mechanism unit 500 includes polygonal printing layers 540, 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) Since the printing layers 540 and 541 are polygonal and are installed eccentrically from the printing tool rotating shafts 510 and 528, the printing layers 540 and 541 are set at the printing position during the printing tool rotation (one rotation of 510). Only the printed side is stamped. There are no stains on the paper. Note that the printing rubber supporting side of the printing eraser 540° 541 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 in the forward position the paper is slightly pushed up from the conveying surface toward the free rotation wheel, and in 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 restraint current is applied during the stoppage, so that the printing tool can be reliably stopped and restrained (positioned).

(21) The printing tool drive motor 520 is a pulse motor, and is driven in synchronization with the paper feed synchronization pulse (encoder pulse) during stamping, so that the printing tool l can be accurately and easily driven in synchronization with the paper.

(22) The position of the base frame can be manually adjusted in a direction perpendicular to the paper feeding direction, and the stamp position in this direction can be adjusted and 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 is removably attached to 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 device can be changed by turning the manual rotary wheel 522 with the unit 500 pulled out, as shown in FIG. 9c of the 6-mechanism unit 50.
Since 0 can be withdrawn freely, changing this date is also relatively easy.

(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) Mechanism - Controlled approximately in accordance with the g division =...
and an operation board control unit, with the operation board control unit serving as a main control unit and the other control units serving as slave control units.
Data indicating paper size, orientation, fold type, need for punching, need for stamping, stamp content, etc. is given to the operation board control unit from the operation board and/or a host such as a copying machine, and the operation board control unit sets the sheet processing mode. Judging,
The processing mode of each slave control unit is determined based on the determined sheet processing mode, and this is sent to the slave control unit.

Therefore, the control operations of the slave control unit are relatively simple, and the slave control unit performs sheet processing control, paper jam determination and abnormality determination, and paper jam detection for the mechanical unit 1- assigned to it.

All you have to do is stop the protection in the event of an abnormality and send it to the main control unit.The overall movement of the sheet processing machine 900 and the movement of each mechanical unit are consistent, allowing a quick response in the event of trouble, and the severity of the trouble. is prevented.

(27) The operation board control unit receives signals and data obtained from the settings of a host such as the copying machine 800.

If the signals and data obtained under the operating board settings overlap, the former is prioritized over the latter and the processing mode is determined, assuming that signals and data that cannot be obtained from the host are obtained under the operating board settings. Prepare the underlying data.

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, there are few errors in judgment and processing, and the operation of the host and the operation of the sheet processing machine are synchronized or matched.

Since the sheet processing machine 900 operates in accordance with the input from the operation board when the host is not connected (C), 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
Vertical 2-fold, Vertical J IS 2-fold, #1 2-fold.

Since the lower fold types that need to be specified in the vertical folding mechanism unit 100 and the blade folding machine groove 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, low profile data and size data, as well as
Based on the upper digit data, the 90° tan mechanism unit l-
Since the sheet processing machine 900 automatically determines and automatically sets whether a 90° turn is necessary, which needs to be specified at step 200, 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 at the time of paper jam is reduced. Furthermore, in the event of a paper jam, the host is notified quickly and the amount of unnecessary paper 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.
