Description

Description: TECHNICAL FIELD The present invention receives paper discharged from an image processing apparatus such as a copying machine, a facsimile machine, a printer, or the like, or a sheet of other paper, and folds the sheet into a predetermined shape. The present invention relates to an automatic sheet processing apparatus for performing additional processing such as punching and imprinting in addition to performing.

2. Description of the Related Art For example, conventionally used blueprints (diazo copy) and recent electrophotography (transfer type copy) can obtain copies of various sizes. Generally, a copy of A size larger than A4 should be folded to A4 size and B larger than B5.
A copy of the size is folded into B5, punched if necessary, and stamped if necessary.

Since this type of sheet processing is conventionally performed by hand, it takes a lot of work and the accurate folding shape, punch hole, stamp position, etc. are not always obtained. Many do not know how to fold.

On the other hand, for example, automatic paper processing such as receiving copied sheets of various sizes and folding the sheet into a predetermined shape, punching holes at predetermined positions, or stamping at predetermined positions. An automatic sheet processing apparatus for applying the above has been proposed by the present applicant (Japanese Patent Application No. 59-215932).

In this sheet automatic processing apparatus, the fold types of the sheet fold are A2 size JIS fold or A4 size fold and A3 size JIS fold, or 2 for A size sheet.
There is a trifold. The same applies to B size sheets, with B3 size JIS folds or 4 folds, B4 size JIS folds,
Or there are two folds. In this sheet automatic processing apparatus, for example, A2
When the process of four-folding of size or two-folding of A3 size is performed, the image surface is on the inside after folding. For this reason, if the stamp processing is performed after the sheet folding processing, the stamp is imprinted on the back side, so that the sheet becomes a processing error and the copy is wasted. The same applies to punch holes. If the punch hole processing is performed after the four-fold processing or the two-fold processing, the punch holes will be additionally formed. Therefore, in some cases, the copy image is crushed and copied. Is wasted.

An object of the present invention is to prevent damage to a sheet due to additional processing such as punching and stamping in an automatic sheet processing apparatus.

Configuration To achieve the above object, in the present invention, a sheet folding mechanism, an additional processing mechanism arranged downstream of the sheet folding mechanism, a processing instruction input means, and a sheet folding and additional processing are controlled according to the processing instruction input. In the automatic sheet processing apparatus including the control means, the processing instruction input means includes sheet folding selection means for selecting a folding type of sheet folding and additional processing selection means for selecting the additional processing, and the control means selects sheet folding. According to the folding type selected by the means, a means for prohibiting the selection of the additional processing by the additional processing selection means is provided. Further, the control means, when the processing instruction input means selects additional processing,
Depending on the fold type selected by the sheet fold selection means, the selection of the additional processing of the processing instruction input means is canceled.

According to this, since the wrong addition processing is not selected, there is no processing error such as stamping on the back side of the image side of the sheet, and the image on the sheet is crushed through the punch holes to waste the sheet. Disappears.

In a preferred embodiment of the present invention, when the sheet fold selection means selects four-fold or two-fold, the additional processing selection means prohibits the additional processing from being selected, and
The additional processing mechanism for performing the additional processing is a punch mechanism and a stamp mechanism, which are arranged in this order in the sheet feeding direction.

Other objects and features of the present invention will become apparent from the following description with reference to the drawings.

Next, the configuration of each mechanism unit will be described with reference to FIGS. 5a to 8c.

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

The vertical folding mechanism unit 100 includes rollers 104 and 108 for inputting paper, an input gate claw 112 for determining the paper feeding direction, and three vertical folding rollers 1
16, 118, 120, vertical folding conveying rollers 162, 166, end folding folding plate 197, vertical folding position setting registers 154, 156, etc. are provided, and the required rollers are connected to the drive power system (not shown) of the unit 100. ing.

The paper entry gate claw 112 is fixed to the rotary shaft 110, and the rotary shaft 110 is rotationally driven by a solenoid 114. When the vertical folding is not instructed, the solenoid 114 does not energize the sheet feeding gate 112 and places it at the solid line position in the figure. In this state, the paper sent directly below the paper sensor 174 will be
It is accepted at 08, but hits the lower curved surface of the claw 112, is bent downward, and goes straight to the unit 200. When the vertical folding is instructed, the solenoid 114 is energized when the sensor 174 detects the paper, and the tip of the claw 112 is moved to the lower roller shaft 106.
Descends in the direction (state indicated by a chain double-dashed line in FIG. 4). In this state, the paper sent directly below the sensor 174 is
It is received at 04, 108, rides on the upper surface of the claw 112, and is fed toward the vertical folding rollers 116, 118, 120.

The vertical folding rollers 120 and 118 are about the thickness of paper (about 5/100 mm)
, But the roller 116 is 1 in any state.
Do not touch 20. The vertical folding roller 116 is directed by the shaft body 122 and is rotatable about it. A plunger of a solenoid 124 is connected to the arm that pivotally connects the roller 116. When the solenoid 124 is energized, the roller 1
16 separates from the roller 118 and paper that has passed through the upper surface of the pawl 112 can enter between the rollers 118 and 116. When the solenoid 124 is not energized, the roller 116 is in pressure contact with the roller 118.

The fixed register 178 is for positioning the A2 short side during vertical folding, the fixed register 154 is for positioning the A2 long side during vertical folding of A2 / 4 folds, and the movable register 126 is for positioning the B3 short side during vertical folding. And the movable register 156 is B3 when B is folded in 4 and folded vertically.
3 For long side positioning.

The movable registers 126 and 156 have solenoids 13 respectively.
0 and 160 plungers are connected. solenoid
When 130 is not energized, the register 126 is retracted from the vertically folded paper transfer path. When the solenoid 130 is energized, the register 126 advances into the vertically folded paper transport path and stops incoming paper there. When the solenoid 160 is not energized, the register 156 is retracted from the vertically folded paper transfer path. Solenoid 1
When 60 is energized, the register 156 advances into the vertical folding paper transport path and stops incoming paper there.

The rollers 166 and 162 energize the solenoid 124 and the rollers 116
Is for feeding the paper introduced through the upper surfaces of the claws 112 by the rollers 104 and 108 to the register 178 or 126 in the state where the is pulled up. After applying the leading edge of the paper to the register 178 or 126, the solenoid 124 is de-energized and the vertical folding roller 1
Paper is sandwiched between 16 and 118. In this state, the rollers 116 and 118 feed the paper toward the register 154 or 156,
When one side of the paper hits the register 154 or 156, the paper rolls.
Deflection at the place out of 116-118, this deflection becomes large and it is caught between rollers 118-120 and folded in half vertically,
It is delivered to the unit 200 through a delivery port (a slit-shaped opening parallel to the axis of the vertical folding roller) immediately below the rollers 118 and 120. A steel ball 169 is placed on the roller 166 and a steel ball solenoid 164 is placed on the roller 162 so that the rotation of the rollers 166 and 162 does not give a resistance to the movement of the paper when the sheet is folded in half.
Are facing each other.

The steel ball 169 is supported by a ball support (not shown) so as to be rotatable in multiple directions. The steel ball 169 constantly contacts the roller 166, and when the paper arrives, the paper is pressed against the roller 166 by its own weight, and rotates with the movement of the paper. To do. Therefore, when the paper is moving immediately below 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 the direction orthogonal to the axis of the vertical folding roller 116 (vertical two-fold)
In addition, the steel ball 169 rotates as the paper moves, so that it does not hinder 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. The steel ball 165 generally acts on the paper in the same manner as the steel ball 169, but when the paper is driven in the direction orthogonal to the axis of the vertical folding roller 116 (vertical two-fold), the electric coil is energized. Steel ball 165 and roller 162
Pull up from (paper) to reduce the frictional resistance of the roller 162.

The folding plate 197 is fixed to a carriage 198, and the carriage 198 is guided by a guide bar 199 so as to be reciprocally movable in the arrow direction (the axial direction of the roller 116). Carriage 19
A link arm 196 is pivotally attached to the 8, and another link arm pivotally attached to this link arm is fixed to the output shaft of the half-rotation clutch 136. Half-turn clutch 136
The gear fixed to the input shaft of is engaged with the drive power system (not shown) of the unit 100. Half-turn clutch 136
When it is energized, the link arm 196 is rotated half a clockwise direction to drive the carriage 198 (that is, the folding plate 197) to the right, and when the energization is cut off, the link arm 196 is further rotated half a clockwise direction. Rotate the carriage 198 (that is, folding plate 1
Drive 97) to the left. FIG. 5a shows the folded plate 197 in the standby position.

To the right of the folding plate 197 is the push plate 138. The push plate 138 is fixed to a U-shaped arm 140, and the arm 140 is pivotally attached to a carriage 142. Carriage 142 is a guide bar
It is guided reciprocally by a guide bar 193 parallel to 199. 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. A roller 152 is in contact with the U-shaped arm 140, and the roller 152 is pivotally attached to one end of the rotating arm 148. The plunger 150 of the solenoid 150 is coupled to the other end of the rotating arm 148. In the state shown in FIG. 5a (standby state), the U-shaped arm 140 is held loosely by the roller 152. The U-shaped arm 140 has a U-shaped arm 1 due to the spring 145 (left pull) and the spring 144 (upward pull).
Push plate 138 fixed in a dogleg shape to 40
Is rising above. In this state, rollers 116-118
The paper fed in between passes through the space between the folding plate 197 and the pressing plate 138. When the solenoid 150 is energized, the arm 148 rotates counterclockwise and the roller 152 strongly presses the arm 140. 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 and presses 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 when overcoming 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, and the pushing plate 138 also moves to the right. When the U-shaped arm 140 is separated from the roller 152 to the right, the U-shaped arm 140 is prevented from returning to the left by the roller 152. When the half-turn clutch 136 is de-energized in this state, the folding 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, whereby the push plate 138 moves upward while the push plate 138 moves upward, and moves to the left by the force of the spring 145. The standby state shown in FIG.

FIG. 5b shows an enlarged plane of the folded plate 197, FIG. 5c shows a section taken along the line VC-VC, and FIG. 5d shows a section taken along the line VD-VD. The edge of the folding plate 197 on the side of the pressing plate 138 is a substantially knife edge whose lower surface is inclined (dotted line) so that the paper PR (two-dot chain line) can be folded and easily gripped. Further, the front end of the folding plate 197 is formed in a letter shape so as to prevent the escape of the paper. When the A2 paper is positioned by the register 178 and the B3 paper is positioned by the register 126, the paper PR (two-dot chain line) 1
As shown in FIG. 5b, the corner rides on the folding plate 197 in a triangular shape, and the paper PR is between the folding plate 197 and the pressing plate 138. This state is shown in FIG. 5e. When the solenoid 150 is energized in this state, the paper is pressed against the lower paper guide plate (not shown) by the pressing plate 138. When the half-rotation clutch 136 is energized, the folding plate 197 moves to the right as shown in FIG. 5f, folding the corner of the paper to reach above the pressing plate and the paper on it. When the folding plate 197 further advances, the push plate 138 also moves to the right,
138 comes out from the folded part of the paper to the right. Half-turn clutch 136
When the energization is cut off, the folding plate 197 moves leftward 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 pressing 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 in the drawing, in parallel with the fixed register 154 used for vertical 2-fold for A2 / 4-fold and the movable register 156 used for vertical 2-fold for B3 / 4-fold, vertical 2-fold for A2-JIS folding A movable register (154J) to be used and a movable register (156J) to be used for vertically folding B3 / JIS are installed, and each solenoid (160AJ, 160BJ: not shown) is used to selectively advance to the paper transport path. However, since the drawing becomes complicated, the drawing 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 is constantly rotating while the main power system is moving. Rollers 162,166 and 1
The 18 and half-turn clutch 136 input power systems are all coupled together selectively to the main power system via one clutch. The main power system starts moving in response to the start signal and stops when a predetermined condition is satisfied. For example, it is stopped when an end signal arrives, when a predetermined time has elapsed since the paper was not detected by the sensor 174, and when a paper jam was detected. 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 the paper is jammed while the unit 100 is passing through (solenoid 114 is off), the roller 104 is separated from 108 and the jammed paper is removed. When the paper is jammed in the vertical folding mode (solenoid 114 ON) and the jammed paper is caught in the three of the vertical folding rollers 116, 118 and 120, it is difficult to remove it, so connect the grip 180 to the roller shaft 170. By rotating the grip 180, the rollers 162, 166 and the vertical folding rollers 116, 118, 120 are manually rotated.

Next, details of the operation of the vertical folding mechanism unit 100 will be described with reference to FIG. 5a.

Operation of the Vertical Folding Mechanism Unit 100 (1) A2, 4-fold mode ... When the sensor 174 detects paper, the solenoids 114 and 124 are energized. When the sensor 176 detects the paper, the rotary encoder 297 (Fig. 6a) starts pulse counting, and when the count value reaches the timing value at which the entire leading edge of the paper contacts the fixed register 178, the solenoid 164 is energized. After the steel ball 165 is raised, the solenoid 124 is de-energized. When the sensor 176 does not detect the paper (since the paper is already caught in the roller of the next unit 200), the energization of the solenoids 164 and 114 is cut off.

(2) A2 / JIS folding mode ... When the sensor 174 detects paper, the solenoids 114, 124 and 160AJ (not shown) are energized. When the sensor 176 detects the paper, the rotary encoder 297 (Fig. 6a) starts pulse counting, and when the count value reaches the timing value at which the entire leading edge of the paper contacts the fixed register 178, the solenoid 164 is energized. After the steel ball 165 is raised, the solenoid 124 is de-energized. When the sensor 176 does not detect the paper (since the paper has already been caught in the roller of the next unit 200), the solenoids 164, 160AJ (not shown) and 114 are de-energized.
The above is the case where the end face of A2 paper is not folded, but when folding the end face, before energizing the solenoid 164, the solenoid 1

When the sensor 176 detects the paper, the rotary encoder 297 (Fig. 6a) starts the pulse count, and when the count value reaches the timing value at which the entire leading edge of the paper comes into contact with the movable register 126, the solenoid 124 is energized. Turn off and energize solenoid 164. When the sensor 176 does not detect the paper (since the paper is already caught in the roller of the next unit 200), the energization of the solenoids 164, 130, 160J and 114 is cut off.

(5) Modes other than the above ... All the solenoids are de-energized and the rollers 104 and 108 are driven.

(6) In addition to this, normal paper jam detection and mechanism stop during jam detection.

Next, referring to FIG. 6a, the 90 ° turn mechanism unit 200
The configuration of will be described.

In the unit 200, the paper transport system is a vertical origami paper introduction system,
It consists of a paper feed system without vertical folding, edge feeding system, paper feeding system, 90 ° turn feeding system and feeding system. The general categories of paper transport elements are summarized below.

Vertical origami introduction system: rollers 212,216 and rollers 286,288,29
0,292,294,296.

Rollers 292, 294 and 296 are pivotally mounted on shaft 298,
A plunger of a solenoid 299 is connected to the shaft 298 via an arm. When solenoid 299 is energized, rollers 292, 294 and 296 are respectively rollers 286, 288 and 2
Pressed to 90. Rollers 286,288 and 290 rotate in a direction that drives the paper towards registers 262,264.

Edge aligning feed system: roller 272,276,280,284, steel ball solenoid 274,278,291,295, roller 242,254, steel ball solenoid 244,
256.

Steel ball solenoids 274,278,295 and 291 are de-energized and steel balls 275,279,293 and 289 are rollers 272,276,280 and 284.
The paper is pressed against each of the
Driven towards 262,264. Edge of paper is register 262,2
When it comes into contact with 64, the paper is slightly bent, but since the pressing force exerted by the steel ball is small and the steel ball itself does not apply the driving force to the paper, this bending does not increase. Steel ball solenoid 274,
When 278, 295 and 291 are energized, the paper becomes free and the recoil force of the bend causes it to return to a smooth surface. In this state, the edge of the paper is in contact with the registers 262 and / or 264.

Vertical folding paper introduction system: rollers 204, 208.

A rotary encoder slit 299 is coupled to the drive roller 208.

Unit 100 between the delivery rollers 104 and 108
If paper jam occurs when paper is sandwiched between 200 rollers 204 and 208, the unit 100 or 200 will be used as a sheet processing machine.
When pulling it out from the 900 main unit, the jam paper will be torn and it will be difficult to remove it.

Therefore, a cutter 223 is installed on the upstream side of the rollers 204 and 208. The cutter 223 is fixed to the carriage, and the carriage is guided by a guide bar 225 so as to be capable of reciprocating 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 in the normal direction, the cutter 223 moves A2 from the position shown in Fig. 6a (front standby position) to the back.
It travels a little longer than the short edge, which cuts the jammed paper. When that distance is reached, the motor 229 is once stopped there, then the motor 2 is closed until the switch 231 is closed.
29 is biased in the reverse direction and returns to the standby position shown in the figure.

Paper passing system: rollers 218,222,226,230,242,250,254, steel ball solenoids 220,224,228,232,244,252,256.

The shafts 246 and 258 of the rollers 242 and 254 are inclined in a direction intersecting a direction (direction in which the shafts 248 and 260 extend) orthogonal to the paper feeding direction, respectively. For this reason, the shafts 246 and 258 are connected to the shafts 248 and 260 by a universal joint having a spring as a main component. As a result, rollers 246 and 25
4 gives the paper a driving force toward the registers 264 and 266 (an approaching driving force to the register 264).

Note that the register 266 is provided to adjust the posture of the paper. As will be described later, in the unit 200, all the papers are adjusted in posture and position so as to be aligned with the registers 262 and 264, and the register 266 is provided to ensure this more accurately. Solenoid 27 in register 266
When the plunger 0 is connected and the solenoid 270 is energized, the register 266 moves up and advances into the paper transport path. The register 266 is advanced to the paper conveyance path during the edge green alignment drive, the edge alignment drive is ended, the sheet passing (paper discharge) drive is started, and after the timing when the entire leading edge of the paper reaches the register 266. Turn off the solenoid 270 and turn off the register 266.
By retracting the paper, the posture of the paper is adjusted.

90 ° turn feed system: roller 238, 234, steel ball solenoid 236,
240.

The roller 238 rotates at the same linear velocity as the paper-passing roller, but the roller 234 rotates at a linear velocity of 1 / 3.43 of the linear velocity of the roller 238. All the roller shafts other than the shaft of the roller 234 of the 90 ° turn feed system rotate at the same speed.

Since the linear velocity of the roller 234 is slow, when the steel ball solenoids 236 and 240 are de-energized and the steel balls 237 and 241 are on the paper, a rotational force, that is, a rotational force that rotates clockwise is applied to the paper. .

Sending system: rollers 211,207.

A hand grip 215 is fixed to the roller shaft of the drive roller 211.

The main power system of the unit 200 is the shaft 206 of the drive roller 208 for the vertical folding paper introduction system, and the drive rollers 216, 28 for the vertical folding paper introduction system.
6, the roller shaft of the edge aligning feed system and the shaft 3 of the roller 238 of the 90 ° turn feed system are all at the same speed (unit 100
The speed is the same as that of the roller shaft 106, and the unit 100 is connected at a speed of about 3 times the sending speed of the copying machine 800.
The shaft of the roller 234 of the ° -turn feed system is connected to the main power system of the unit 200 via a reduction gear. The shaft 213 of the drive roller 211 of the delivery system is connected to the main power system of the unit 200 by a gear having a relatively small number of teeth, and rotates at a speed higher than the rotation speed of the roller shaft 206 and the like. Therefore, when the paper reaches the rollers 207 and 211, the paper is delivered to the unit 300 at high speed in a form of being pulled by these rollers. At this point, the paper is not between the rollers 208 and 204, but is pressed against the rollers 250, 242, 254, etc. by the steel balls, so the paper is not tensioned enough to break it.

Next, the operation details of the 90 ° turn mechanism unit 200 are described in 6a.
It will be described with reference to the drawings.

(1) A3 / horizontal / JlS folding or two-fold mode ... In these modes, as shown in Fig. 3a, the A3 / horizontal posture is changed to A3 / longitudinal posture by the unit 200. Paper is unit 100

When sensor 217 detects paper, steel ball solenoid 220,228,2
Steel ball solenoids other than 24,232 are energized to pull up those steel balls. The paper is fed by rollers in contact with steel ball solenoids 220,228,224,232 and rollers 208 and 204. In addition, the counting of the pulses of the encoder 297 is started.

When the count value reaches the predetermined value assigned to A3, the steel ball solenoids 220, 228, 224, 232 are energized and the steel ball is pulled up. Almost at the same time, the electric currents of the steel ball solenoids 240 and 236 for 90 ° turn were cut off, and the rollers 234 and 2
38 applies rotational force to the paper. This makes the paper 6b

When the 7 pulse count is started and the count value reaches a value corresponding to the timing when the tail end of the paper passes through the register 226,
All current to the steel ball solenoids is cut off, provided that the sensors 217, 219 and 221 do not detect the paper. The control timing of the 90 ° turn of A3 described above is shown in FIG. 6d.

(2) A4 / longitudinal mode: The operation of the unit 200 is the same as the 90 ° turn operation of A3 described above. However, because the size is different, the control timing is different. 90 in A4 / Portrait mode
The posture of the paper at the ∘ turn is shown in Fig. 6c, and the control timing is shown in Fig. 6e.

(3) The operation of B3 / horizontal / 90 ° turn and B5 / vertical 90 ° turn is the same as in (1) above. However, because the size is different, the control timing is different.

(4) Roller 208,204 Arriving paper straight through ... A3, sideways, plain through control timing is shown in Fig. 6f. In clearing, the paper is sent to the unit 300 with the paper being placed in a position to fit the register 266 and the registers 262 and 264.
Do not rotate the paper. Fig. 6g shows the control timings for A4, horizontal, and plain. Again, the paper register 266
And send it to the unit 300 in a position that fits the registers 262 and 264. The same applies to the control of the plain mode of other sizes and postures. However, the control timing differs depending on the size and the paper-feeding posture.

(5) A2 / Vertical / Four-fold or JlS folding mode ... In this mode, vertical origami paper is fed from the unit 100 to rollers 216-212.
It will be sent in the meantime. In this mode, when the sensor 174 of the unit 100 starts counting the generated pulses of the encoder 297 when detecting the paper, and when the sensor 174 returns to the paper non-detection, the steel ball solenoids 278,295,274,291,220,228,
Energize 224,232,274,240,252,244,256. Unit 100
At, the paper is folded in half and sent to the unit 200.
In the unit 200, rollers 216 and 212 feed the paper in the direction of arrow 203. Then, the tip is sent by inertia until it abuts on the inner register 235. The count value is the first value (unit 20
The first value for 0 and the seventh value for unit 100.
(Corresponding to the value of), the paper has already passed between the rollers 216 and 212, the solenoid 299 is energized, and the steel ball solenoids 278,295,274,291 are de-energized. As a result, the paper moves toward the registers 262 and 264. When the count value reaches the second value, the paper has passed the rollers 292 and 286, and the energization of the solenoid 299 is cut off. When the count value reaches the third value, the paper hits the registers 262 and 264, the steel ball solenoids 278,295,274,291 are energized, and the steel ball solenoids 220,228,224,232,240,252,244,256.
Is turned off, and the paper is sent to the rollers 207 and 211 and sent to the unit 300 while being applied with a pulling force (by the rollers 242 and 254) to the register 264. The register 266 is continuously in the retracted position.

(6) B3, vertical, 4-fold or JlS fold ... Same as (5) above. However, the control timing differs depending on the size.

In addition, when paper jam occurs in the unit 200,
When the jammed paper is straddling the units 100 and 200 at the rollers 208 and 204, the switch 237 (FIG. 1) is pressed and the units 100 and / or 200 are pulled out from the main body of the sheet processing machine 900. When the switch 237 is closed for a moment, the cutter 223 moves inward a little longer than the A2 short side length to cut the jammed paper, returns to the front, and the switch 231 returns to the closed state (shown in FIG. 6a). Stop). When the jammed paper straddles the vertical folding roller of the unit 100 and the rollers 216 and 212 of the unit 200, the unit 100 and / or 200 may be pulled out as it is. At this time, by pulling out the unit, the jammed paper is pulled out from one unit. For safety in advance, the unit
Fully rotate the grip 180 of 100 or the grip 215 of unit 200 before pulling out the unit. By rotating the grip 180, the rollers of the unit 100 rotate and feed out the paper, and the unit 2
By turning the grip 215 of 00, the roller of the unit 200 rotates to pull out the paper.

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

The main element of the blade folding mechanism unit 300 is the horizontal folding rollers 318, 3

And a second gate pawl 350 for controlling the supply of paper from the horizontal folding roller to the second folding conveyance path. Rollers 304, 308 and rollers 31 that receive the paper from the unit 200 are provided in the paper input conveyance path.
There are 0,312,314,316 etc. Rollers 304 and 308 are unit 200
The rollers 207 and 211 rotate at the same speed, but the rollers after the roller 310 rotate at a higher speed than the rollers including the lateral folding roller. When one end of the long side of A2 reaches the horizontal folding roller, the other end has already passed the rollers 304 and 308. The sensor 386 detects the paper on the paper input conveyance path.

The first folding conveyance path is a conveyance path that guides the paper fed out by the horizontal folding rollers 318 and 320, and the movable register 336, which determines the first folding position of the B4 / JlS folding, and the first folding of the A3 / JlS folding. A movable register 338 for defining the position, a movable register 340 for defining the first folding position of the B3 / JlS fold, and a movable register 342 for defining the first folding position of the A2 / JlS fold are arranged. Further, although not shown, the register used for the A3 half-fold is provided at the left position of the movable register 342. Movable register 336,338
And 340 are solenoids 336S, 346 and 340, respectively.
Plungers S (not shown) are connected to each other and retracted from the paper transport path when the solenoid is not energized. When the solenoid is energized, it advances into the paper transport path and stops the paper movement.

When the first gate claw 351 is in the plain guide position (between the rollers 318 and 322 and facing the roller 320), the paper that is about to be sent out toward the first folding conveyance path by the horizontal folding rollers 318 and 320 is It is guided by the 1-gate claw 351 between the horizontal folding rollers 320 and 322 and does not face the first folding conveyance path. First
When the gate claw 351 is retracted from the plain guide position, the horizontal folding rollers 318 and 320 feed the paper toward the first folding conveyance path. At this time, the paper starts to bend on the exit side of the rollers 318 and 320 from the time when the leading edge of the paper hits the register (336, 338, 340 or 342) in the first folding conveyance path, and when the amount of bending increases to a certain degree, the paper doubles there. Turned rollers 320 and 322
Bite into. This means that the lateral folding has been performed. The folding position is determined by which register has advanced to the transport path.

The second folding conveyance path is a conveyance path that guides the paper fed by the horizontal folding rollers 320 and 322, and is the second conveyance path of the B3 / JlS fold.

A movable register 362 for determining the folding position in the two horizontal folds of 360, B3 / JlS fold, and a movable register 364 for determining the fold position in the two horizontal folds of A2 / JlS fold are arranged. Plungers of solenoids 338S, 370 and 362S (not shown) are connected to the movable registers 358, 360 and 362, respectively, and retracted from the paper transport path when the solenoids are not energized. When the solenoid is energized, it advances into the paper transport path and stops the paper movement.

When the second gate claw 350 is in the plain guide position (between the rollers 320 and 324 and facing the roller 322), the paper that is about to be sent out toward the second folding conveyance path by the horizontal folding rollers 320 and 322 is The two-gate claw 350 guides the sheet between the horizontal folding rollers 322 and 324 and does not face the second folding conveyance path. Second
When the gate claw 350 is retracted from the plain guide position, the horizontal folding rollers 320 and 322 feed the paper toward the second folding conveyance path. At this time, the paper starts to bend on the exit side of the rollers 320 and 322 from the time when the leading edge of the paper hits the register (358, 360, 362 or 364) in the second folding conveyance path, and when the amount of bending becomes large, the paper doubles there. Turned rollers 322 and 324
Bite into. This means that the lateral folding has been performed. The folding position is determined by which register advances to the second folding conveyance path.

The paper sent by the horizontal folding rollers 322 and 324 is roller 374.
And the roller abutting against it is sent out to the punch mechanism unit 400.

A unit 200 is installed above the rollers 304 and 308 in the paper feeding path.
A cutter 376 for cutting 300 sheets of jammed paper is arranged. The support structure and operation mode of the cutter 376 are the same as those of the 90 ° turn mechanism unit 200 shown in FIG. 6a, and thus detailed description thereof is omitted here.
The cutter 376 is driven in response to the closing of the switch 390 (FIG. 1). The paper sensor 388 detects paper in the paper discharge path.

A positioning arm 570 fixed to a case frame (not shown) is located immediately below the stopper 566. This arm 5
The 70 has a large number of rectangular notches for receiving the lower end of the stopper 566. By pushing the stopper 566 upward and pushing the base frame to the back side, the stamp position on the paper moves to the back side in the direction orthogonal to the paper feeding direction. The stamp position moves to the front by pulling it toward you. As described above, the stamp position in the direction orthogonal to the paper feeding direction can be manually adjusted. The stamp position in the paper feed direction is adjusted by adjusting the drive start timing of the pulse motor 520 (support plates 512, 526) based on the arrival of the leading edge of the paper.
As will be described later, this timing is set by an electric signal and is automatically performed.

The ink roller 560 is pivotally attached to the support frame 584 as shown in FIG. 8b. Sliders 586 (two) are mounted on the support frame 584 so as to be movable in the direction of arrow 593 and in the opposite direction. A compression coil spring 589 is interposed between the two sliders 586, and gives a force to pull them apart. A notch 590 for pin engagement is formed in the support frame 560, and a pin guide hole 587 and a pin guide groove 588 continuous with the pin guide hole 587 are formed in the slider 586.

After the paper is detected by the sensors 598A and 598B, the forward rotation is urged at a speed synchronized with the paper moving speed of the pulse motor 520 to rotate the printing tool first and second support plates 512 and 526 counterclockwise to perform printing. Solenoid 578 just before the surface faces roller 572
Is energized to pull up the roller 572, and when one side of the printing surface passes the roller 572, the energization of the solenoid 578 is cut off to lower the roller 572, so that one printing is performed. While the printing surface moves from the standby position (home position) shown in FIG. 8a onto the roller 572, the printing surface comes into contact with the surface of the ink roller 547 and slightly compresses the surface of the roller 547. As a result, the ink of the roller 547 is transferred to the print surface. An example of the stamp image is shown in FIG. 12c.

An upper cover 594 is attached to the base frame 502. Top cover
The state in which the 594 is attached is shown in FIG. 8c. Incidentally, FIG. 8c shows
The state in which the date changing wheel portion of the date stamper 556 is moved right below the opening 594 of the cover 594 by rotating the manual rotating wheel 522 is shown. The date can be changed in this state. In addition,
Although the date is adjusted manually like this,
A roller for changing the date is provided at a position on the base frame 502 that can face the date changing wheel of the date stamper 556 so that the roller can be moved forward and backward by a solenoid or the like, and the motor 520 is used when changing the date. Alternatively, the date stamper may be driven to set at a position facing the changing roller, and the roller may be pushed out and pressed against the date changing wheel to rotate the roller. In this way, the date can be changed automatically. Further, a drive mechanism may be coupled to the base frame 502 to automatically drive the base frame 502 in a direction orthogonal to the paper feeding direction.

Details of the operation of the stamp mechanism unit 500 and the skew and jam detection operation will be described later with reference to the flow chart shown in FIGS. 12a and 12b.

Next, the vertical transport mechanism unit 600 will be described with reference to FIGS. 1 and 4.

The vertical transport mechanism unit 600 has a stamp mechanism unit 500
Rollers 580 and 582 feed the paper. In the unit 600, drive rollers 604, 610, 616, 622 and 628, driven rollers
606, 612, 618, 624 and 630 feed the paper upward and feed the paper to the paper discharge mechanism unit 700. The driven rollers 606, 612, 618, 624, and 630 can be moved back and forth with respect to the drive roller, and are constantly pressed by the compression coil spring toward the drive roller. 636 is a handshake for pulling out. 638 and 640 are paper sensors.

A grip 634 is fixed to the roller shaft of the drive roller 628. The roller shafts 602, 608, 614, 620, 626 of all driving rollers are connected to the power system of the unit 600, and by rotating the roller shaft 626, all driving rollers rotate. When the grip 634 is turned during paper jamming, all rollers rotate and the jammed paper moves upward or downward. When the jammed paper straddles the stamper mechanism unit 500 and the vertical transport mechanism unit 600, before pulling the unit out of the main body of the sheet processing machine 900, the grip 634 is turned to feed the paper into the unit 600, and then the unit 600 is moved to the sheet processing machine 900. Pull out from the main body and take out the paper.

Next, the paper discharge mechanism unit 700 will be described with reference to FIGS. 1 and 4.

The paper discharge mechanism unit 700 includes the paper receiving rollers 706 and 708, the gate claw 712 that determines the paper feeding direction, the transport path to the sorter 1000, the transport rollers 720 and 722 and the paper sensor 736, and the transport to the tray ET placed on this transport path. Path, the feed rollers 726, 728 and the paper sensor 734 placed on this conveyance path, and the rotary encoder 730 is fixed to the roller shaft 704.

When it is instructed to discharge the paper to the tray ET, the solenoid (not shown) remains de-energized, and the paper is locked by the gate claw 71.
It is directed to the rollers 726 and 728 on the lower curved surface of 2, and is fed by these rollers in the direction of arrow 701 to reach the tray ET. Sorter 1000
When it is instructed to discharge the paper, the solenoid (not shown) is energized and the gate claw 712 rotates clockwise to guide the paper toward the rollers 720 and 722. The paper is sent by these rollers in the direction of arrow 703 and reaches the sorter 1000.

As described above, up to the rollers 254 of the vertical folding mechanism unit 100 and the 90 ° turn mechanism unit 200, the paper is fed at a speed almost equal to or slightly higher than the paper feeding speed of the copying machine 800, but 90 °. The feed roller 211 of the turn unit 200 and the rollers 304 and 308 of the next blade folding mechanism unit 300 feed the paper at a faster speed, and the rollers after the roller 310 of the blade folding mechanism unit 300 feed the paper at a faster speed. In this way, the feeding speed is set to a downstream extent in the sheet processing machine 900 in order to prevent paper stagnation in the sheet processing machine 900, as soon as paper jam is generated in the sheet processing machine 900, it is faster than the copying machine. This is to stop the paper feeding of (1) to reduce the number of fed papers and to widen the paper feeding interval to the sorter 1000.

The control operation of the microprocessor 14 of the operation board control unit 10 is shown in FIGS. 10a to 10d. 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.

First, refer to FIG. 10a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) 14 initializes the input / output port, registers for temporary data storage, status register (flag), counter (program counter),
A timer (program timer) or the like is cleared (step 1). In the following, the word "step" is omitted in parentheses and only the step symbol is displayed.

When the initialization is completed, the CPU 14 reads the status. In this, first, it is controlled whether or not there is a reading flag (2).
At this point, since the initialization has just finished, there is no read flag, so the routine proceeds to step 3, where the standard data is set in the operation board register. Standard data is paper size: A4 Fold selection: No fold Vertical / horizontal posture: Horizontal Stamp selection: None Stamp position: 0mm Publisher: 1st design (1st publisher stamp) Drawing type: Masked (1st drawing type) Punch selection: No punch Output selection: Tray. When this data set is provided, the data-corresponding indicator lamp is correspondingly turned on. In this state, on the operation board 12, stand by (this is set by initialization), A
4, Indicator lights showing No Folding, Horizontal, No Stamp, 0mm, No Punch, 1st Design, Tray, Preliminary Drawing.

FIG. 9b shows the writing position of the data temporarily written in the 3-byte memory area (one area of the internal RAM of the CPU 14) allocated to the operation board register OBR.

When the standard data is written in the operation board register OBR, the read flag is set (4). Next, referring to the state of the port receiving the input signal from the copying machine 800, it is judged whether or not the signal is transmitted from the copying machine 800 (5). When the signal is transmitted, the signal and data are read in and it is determined whether the signal is a start signal (6). If it is not a start signal, it is judged whether it is an end signal (7). If it is not an end signal, it is data. Therefore, in the input data, the data assigned corresponding to the memory bit of the operation board register OBR is assigned. Updates and writes to the operation board register OBR. When such update writing is performed, 1 is written in the bit indicated as the copier input bit of the operation board register OBR. This 1 indicates that the copying machine 800 has instructed the sheet processing machine 900 about a sheet processing method regarding sheet processing. Although not shown, the CPU 14 retains in memory the data received from the copying machine and indicating the data written in the operation board register OBR (indicating what the write data is). When the data is received from the copying machine 800 and the writing to the operation board register OBR is completed and the process proceeds to step 9 or when there is no input from the copying machine 800 and the process proceeds from step 5 to step 9, the operation board is executed at this step Read the 12 key-ins. Key in key switch 12
If it is due to a to 12i (10), refer to the copier input bit and if it is not 1 (data has not been received from the copier) (11), update the contents of the operation register according to the key-in Then, the on / off of the indicator light on the operation board is updated according to this update, but the selected contents of the stamp selection bit and punch selection bit are checked according to the contents of the key-in at this time, and the result of this check The contents of the operation register are updated according to the key-in, and the on / off of the indicator light of the operation board is updated according to the changes of the operation register (13a to 13f).

That is, if the content of the key-in is fold selection, fold four or two
When the fold selection key-in is performed (13a), it is determined whether the punch selection bit or the stamp selection bit of the operation board register OBR is set to 1 (13b), and the punch selection bit or the stamp selection bit is set to 1. If so, the punch selection bit or the stamp selection bit is unset, and the punch selection bit and the stamp selection bit are reset to 0 (13c). If the punch selection bit or the stamp selection bit is not set to 1, proceed to step 13f, update the contents of the operation register according to the key-in, and update the on / off of the indicator light of the operation board according to this update. To do. If the content of the key-in is punch selection or stamp selection (13d), it is determined whether or not the 4-fold or 2-fold selection bit is set in the operation board register OBR (13e). If the fold selection bit is not set to 4-fold or 2-fold, the key-in for punch selection or stamp selection is accepted, the contents of the operation register are updated according to the key-in, and the on / off of the operation lamp of the operation board is updated. However, if the folding selection bit is set to four-fold or two-fold, key-in for punch selection or stamp selection is not accepted. The content of key-in is not fold or fold selection (13a),
If it is not punch selection or stamp selection (13d), the process proceeds to step 13f, the contents of the operation register are updated according to the key-in, and the on / off of the indicator light of the operation board is updated according to this update.

Here, the operation of the key switch of the operation board 12 will be explained. For example, when the switch 12a is closed, the size designation bit of the operation board register OBR is set to the data indicating B3 after A4. Update to, turn off the A4 indicator and turn on the B3 indicator. Operation board register OBR
Key switch 12 when the size specification bit of is B5
Once a is closed, the size specification bit is updated to the data indicating A2, the indicator light of B5 is turned off and the indicator light of A2 is turned on. In this way, each time the size instruction key switch 12a is closed, the indicator light turns on from the upper side to the lower side in FIG. 9a, and at the same time, the data indicating the size designation bit of the operation board register OBR lights up. The data indicating the size indicated by the light is updated. However, this operation is
This is performed only when the size data has not been received from the device.If the size data has already been received, step 11-12-
Then, the data update and display update according to the key-in are not performed. The CPU 14 also operates in the same manner for key-in by the key switches 12b to 12j. This way copier 8
The operation board gives priority to the input data from 00
This is because the data from the copying machine 800 is more reliable than the setting by 12. When no data comes from the copying machine (for example, when the copying machine is not connected) or when only a part of the required data comes, the insufficient data is updated and set according to the key-in from the operation board 12. No data is given from the copier, and the operation board 12
If there is no key-in, the setting data will be the standard data described above. Around the step development of the flowchart shown in the figure, a start signal for starting the operation of the mechanism of the sheet processing machine is also received from the copying machine 800, and the start key switch 12i of the operation board 12 is used for key-in. However, when part of the data is received from the copying machine 800 (OBR copying machine input bit = 1), the key-in of the start signal due to the closing of the switch 12i is not accepted in step 38. In this way, the start signal from the copying machine is prioritized even when the processing mechanism starts.

The operation board 12 and its key-in reading / data set have meaning when the copier is not connected and when it is connected to the copier that does not transmit all required data. ) Is not connected, or if the host function is not sufficient, it is supplemented with key-in.

By setting the data in step 8 (setting the data received from the copying machine) or setting the data in step 13 (setting the key-in data), or no data is sent from the copying machine (5). If there is no key-in (9), proceed to step 14 in FIG. 10b, refer to the signal level of the signal receiving port from the unit 20, and see if it is ready (paper can be received) (standby: paper cannot be received). Or refer to.

If the vertical folding & 90 ° turn control unit 20 is ready in step 14 of FIG. 10b, it is checked in step 16 whether the unit 30 is ready. If the blade break control unit 30 is ready, in step 18, it is checked whether the unit 40 is ready. If the punch control unit 40 is ready,
At 20 see if unit 50 is ready. If the stamper control unit 50 is ready, the unit is processed in step 22.
See if 60 is Lady. If the vertical transport & discharge control unit 60 is ready, all the units are ready to execute sheet processing, so the operation board register OBR
Set 1 to the ready wait bit of to indicate that processing is possible (2
4) Compare the data in the operation board register OBR with the data in the previous operation board register POBR (25). Since the previous operation board register OBR has been cleared by the initialization of step 1, the contents of both do not match when the process proceeds to step 25 for the first time. This means that the processing mode data transfer to each of the units 20 to 60, which will be described later, is not executed. Therefore, first, in step 26, the data of the operation board register OBR is updated and stored in the previous operation board register POBR, and in the A version processing mode of FIG. 10c,
Proceed to setting to unit 20 (27).

Setting to the unit 20 in A version processing mode of Fig. 10c (2
In 7), first, the size is judged from the data of the size designation bit of the operation board register OBR (271).

If the size is A2, then the folding selection bits of the OBR are referenced (272 to 276). If there is no fold, data indicating A2, vertical, and passing mode is transmitted to the unit 20 (273). When the sheet is folded in four, the data indicating the A2 / vertical folding mode is transmitted to the unit 20 (275). Unit 20 when folded in two
To A2, portrait, and transit mode data (27
7). In addition, if it is JIS folding, unit 20 will be A2
Data indicating JIS vertical folding mode is transmitted (278).

If the size is not A2, proceed to step 279 and A3
See if.

If the size is A3, the vertical / horizontal designation bit of the OBR is referred to, which indicates the vertical (280) and the unit 20.
Send A3, portrait, pass mode to (281). When it indicates the side, refer to the OBR fold selection bit (28
2) If it is unbroken, it sends A20, A3, Transverse mode to unit 20 (283). If there is something wrong, it will send an A3 90 ° turnmode to unit 20.

When the size is A4 (285), the vertical / horizontal designation bit is referred to (286), and if it indicates horizontal (286),
Send A4 / transverse / passage mode to unit 20 (28
7). If it does not indicate the side, the A4 90 ° turn mode is transmitted to the unit 288 (288).

If the size is B version, step 28, the above step
Similar to 27, the mode is transmitted to the unit 20 according to the size and the like. Step 27: A2 to B3, A3 to B4, A4
The content of step 28 can be obtained by replacing it with B5.

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

The CPU 14 of the unit 10 then proceeds to the blade folding mode setting (29) in FIG. 10d. In this step 29, first, the folding selection bit of the operation board register OBR is referred to (291,292,29).
Four). Then, when there is no folding, size data is attached and the passage is transmitted to the unit 30 (295). 4 folds, 2 folds,
In the case of JIS folding, the data of the size designation bit of the operation board register OBR and the data of the folding selection bit are transmitted to the unit 30 (293,296). This completes units 10 to 3
The control operation mode instruction is given to 0 and is set in the microprocessor of the unit 30.

After finishing setting the blade folding mode (29), CP of unit 10
The U14 sets the punch mode (30).

In this, referring to the data of the size designation bit, the data of the folding selection bit and the data of the punch selection bit of the operation board register OBR (301 to 306, 308, 309),
Unit 40 when the final size is A4 and there is punch
Send A4 / punch mode to (307) and final size is B5
Moreover, when punching is present, the B5 / punch mode is transmitted to the unit 40 (310), and in other cases, the non-punch mode is transmitted to the unit 40.

After setting punch mode (30), CP of unit 10
U14 sets the stamp mode (31).

In this case, referring to the stamp selection bit of the operation board register OBR (312), if it is 1 indicating the stamp, the unit 50 informs the unit 50 of the stamp selection bit, stamp position bit, issuer selection bit and The data of the drawing type selection bit is transmitted (313). If the stamp select bit is 0, it sends a non-stamp signal to unit 50.

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

In this case, referring to the paper discharge selection bit of the operation board register OBR (321), if it is 1, the unit 60 is instructed to discharge paper to the sorter (323), and if it is 0, it is instructed to discharge the tray. Yes (322).

When the paper ejection mode setting (32) is complete, the units 20-60
The CPUs of these units hold the received instructions (mode data), respectively.

The CPU 14 of the unit 10 then returns to step 234 of FIG. 10b and goes through step 24 to step 25. Here, the data in the previous operation board register POBR is the same as the previous step 26.
Since it matches the data of the operation board register OBR by executing, the process proceeds from step 25 to step 33. In step 33, all the indicators on the error display panel 33 are turned off and the operation board 12
Turn off the standby indicator of and turn on the ready indicator. Next, the ready signal is output and set to the copying machine 800 (34). Then, returning to step 5 in FIG. 10a, the arrival of a signal from the copying machine 800 and the key-in of the operation board 12 are waited for.

When the start signal arrives from the copier 800 (6), the ready / standby bit of the operation board register OBR is referred to (3
5) If it is 1, normal operation is possible, so start signals are sequentially transmitted to the units 20 to 60 at a predetermined timing (37). Then, again, the process proceeds to the state reading below the step. Upon receiving the start signal, each of the units 20 to 60 starts driving the transport roller and waits for the arrival of the paper at the sensor. When the paper arrives, a predetermined control operation is started.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 20 is in standby (cannot process) or is in standby, the CP of the unit 10
U14 reads this in step 14 of FIG. 10b, and proceeds to unit 20 abnormality processing (15). In this abnormality processing, first, the copier input bit of the operation board register OBR is referred to (151). If it is 1, data is received from the copying machine 800 and an abnormality (standby) is transmitted to the copying machine 800 because the sheet processing has started or has already started (152).
Then, the ready / standby bit of the OBR is set to 0 indicating that the operation is not possible, the ready indicator lamp of the operation board 12 is turned off, and the standby indicator lamp is turned on (153). Next, the abnormal data is received from the unit 20 (154), and if the abnormal data indicates a paper jam, the abnormal display panel corresponding to the position data is displayed.
13 Turn on the upper indicator lamp (156). When the abnormal data indicates that it is not a paper jam, all the indicator lights of the display panel 13 associated with the abnormal mechanism unit are turned on (15
7). Then, the process returns to the state reading after step 5 in FIG. 10a.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 30 is in a standby state (not processable) or in a standby state, the CP of the unit 10
U14 reads this in step 16 of FIG. 10b, and proceeds to the abnormality processing (17) of the unit 30. This abnormality processing (17) is similar to the above-mentioned abnormality processing (15). However, unit 20 of (15)
Should be read as unit 30.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 40 is in standby (not processable) or is in standby, the CP of the unit 10
U14 reads this in step 18 of FIG. 10b, and proceeds to the abnormality processing (19) of the unit 40. This abnormality processing (19) is the same as the above-mentioned abnormality processing (15). However, unit 20 of (15)
Should be read as unit 40.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 50 is in standby (cannot process) or is in standby, the CP of the unit 10
U14 reads this in step 22 of FIG. 10b, and proceeds to the abnormality processing (23) of the unit 60. This abnormality processing (23) is the same as the above-mentioned abnormality processing (15). However, unit 20 of (15)
Should be read as unit 60.

The operation of the vertical folding mechanism unit 100 and the operation of the 90 ° turn mechanism unit 200 provided by the vertical folding & 90 ° turn control unit 20 have been described in the respective mechanism description sections. Therefore, the description of the control operation of this unit 20 is redundant and will not be repeated here.

Further, the operation of the blade folding mechanism unit 300 provided by the blade folding control unit 30 has been described in the mechanism description section of the unit 300. Therefore, the description of the control operation of this unit 30 will be omitted here because it is redundant.

The control operation of the punch control unit 40 and the stamper control unit 50, and the skew and jam paper detection operation of each will be described later.

The control operation of the vertical conveyance & discharge control unit 60 is to drive the paper conveyance roller, detect paper jam, and gate claw 712.
The positioning control is simple and can be easily understood by those skilled in the art from the mechanical description of the units 600 and 700, and therefore the description thereof is omitted here.

Next, the control operation of the microprocessor of the punch control unit 40 will be described with reference to FIGS. 11a to 11c. See also FIG.

First, refer to FIG. 11a. When the power is turned on, the microprocessor of the unit 40 (hereinafter simply referred to as CPU)
Performs initialization (40) and status reading (41). A signal line to the unit 10 is set to standby by initialization.

If the sensor 478, 480A or 480B detects paper as a result of the status reading (41) (42), it means that there is remaining paper, so paper jam is sent to the unit 10 (43) and the switch 476 is sent.
Read the state of (Fig. 1). While in the paper jam, step 44-41-42-43-44-41 -... Now when the switch 476 is closed, read the opening and closing of the switch 460,
If it is open, the cutter 452 is not in the home position shown in FIG. 7, so it waits. When the switch 476 is closed while the cutter 452 is in the home position, the process proceeds to step 44-45-46 to energize the pulse motor 458 in the forward direction and set the timer Tam (46). Tam is the time for the cutter 452 to travel a distance slightly longer than the A2 short side length. When the timer Tam is over (47), the motor 458 is stopped there (48), the motor 458 is energized in the reverse direction, and the timer Tam is set (50). Then, it waits for the switch 460 to close or the timer Tam to time out (51, 52). When the switch 460 closes, the cutter 452 has returned to the home position, and the motor 458 is stopped (56). If the timer Tam times out without closing the switch 460, the cutter 4
Since the return of 52 is abnormal, the urging of the motor 458 is stopped (53), a mechanical abnormality is transmitted to the unit 10 (54), and the routine proceeds to abnormality standby processing (55). The CPU of the unit 40 remains in this abnormal standby until the power is turned on again. Well, timer Tam
If the switch 460 is closed and the motor 458 is stopped by the time the time expires (56), the state of the switch 484 is read (57). If the switch 484 is open, that is, not in the punch unit home position (A4 punch position) (since the initial state when the power is turned on is the A4 punch position), the pulse motor 450 is used to set the punch unit to the home position. Reverse rotation is energized and timer Tba is set (58). Tba
Is the time required for the punch unit to reach the A4 punch position (home position) from the B5 punch position. switch
When 484 is closed (59), the motor 450 is stopped there (6
2). If Tba passes without closing switch 484 (6
0), because it is a mechanical abnormality, stop the motor 450 (61),
Proceed to abnormal standby (55).

When switch 484 is closed and the motor is stopped (62),
Proceed to status reading 41. When the status reading 41 detects that no paper is detected by any of the sensors 478, 480A and 480B (42), the switch 460 is closed (49), and the switch 484 is closed (57), the unit is in the normal standby state. Send Lady to 10 (6
3).

After sending ready to unit 10 (63), it waits for sending from unit 10 (64). Receives when sent (65).
This transmission is the punch mode setting (30) in FIG. 10d.

When the signal from the unit 10 is received (65), proceed to step 66 of Figure 14b to see if the signal is a start signal. If it is not a start signal, see if it is data (67),
If it is data, the received data is stored in the mode register (68) and the content of the data in the mode register is referred to (69, 70). If the contents are punch designation and B version,
The pulse motor 450 is normally driven from the A4 punch position (home position shown in FIG. 7) to the B5 punch position and stopped at the B5 punch position (71). When it stops, it informs the unit 10 of the ready again (63). When there is no punch instruction and when the punch is the A version, the unit 10 is directly notified of the ready (63).

When a start signal is received from the unit 10, all rollers are set to the driving state, the timer Ts is set (72), and the sensor 478 detects the paper or waits for the timer Ts to time out (73,74 ). If the paper does not arrive and Ts times out, there is some trouble in the mechanical units up to the punch mechanism unit 400, there is a status change such that copying is not started in the copying machine, or it is considered that feeding has ended Stop driving (75) and send standby to unit 10 (76) read status
Continue to 41. After this process, the unit 400
Is in the ready state, immediately after that, in step 63, the ready is transmitted to the unit 10 and the unit 10 waits for the start signal to arrive again.

Now, when the start signal arrives and the sensor 478 detects the paper before the timer Ts times out (73), it refers to the contents of the mode register (77, 78a), and when the punch is instructed and the A version is selected, the microprocessor is used. Sensor on counter 1
The number of pulses that the paper moves from 478 to register 426
The number of pulses for moving the paper from the sensor 478 to the register 422 is set in the counter 2 respectively, the pulse of the encoder 730 (Fig. 4) is started to be down counted (79), and the solenoid 428 is energized (80) register. Advance the 426 (for A4) to the paper stop position and wait for the arrival of the paper.

Now, when the time for the paper to move from the sensor 478 to the register 422 position has passed (81), the paper detection state of the sensors 480A and 480B is referred to, and skew and jam are determined (82a, 82a
b, 83a). Then, the control corresponding to the determination result is performed. This is as follows.

(1) When both sensors 480A and 480B detect paper.

If both sensors 480A and 480B detect the paper (82a, 83a), the paper posture is normal, so when the A plate is selected (8
4) Wait until the paper touches the register 426 (8
5) Energize the steel ball solenoids 418 and 482 to pull up the steel balls 419 and 483 (86). As a result, the leading edge of the paper is
Stop in the state where it touches 6.

Next, the solenoid 438 is energized and, after the punch rod enters the hole 444, the solenoid 438 is deenergized to punch a hole in the paper (87). Next, turn off all solenoids 428, 424, 418, 482 (88), refer to the detection status of sensor 480A or 480B (89), and when sensors 480A and 480B become non-detection from paper detection (punched paper exits sensor 480A or 480B). And) Set timer Ts (72) and wait for the arrival of the next paper (73).

(2) When sensor 480A detects paper but 480B does not detect paper.

When the sensor 480A detects the paper (82a) and the sensor 480B does not detect the paper (83a), it is a paper queue, the paper queue is transmitted to the unit 10 (83b), and the solenoid 428 is turned off (88). Therefore, in this case, the paper is discharged without passing through the holes (passing through). After the power supply to the solenoid 428 is cut off, the procedure is the same as (1) above.

(3) When sensor 480A does not detect paper but 480B detects paper.

When the sensor 480A does not detect the paper (82a) and the sensor 480B detects the paper (82b), the paper queue is the same as the above (2), and the paper queue is transmitted to the unit 10 (83).
b), shut off the energization of the solenoid 428 (88). Therefore,
In this case as well, the paper is ejected without passing through the holes (passing through). After the energization of the solenoid 428 is cut off, it is the same as the above (1).

When the paper queue is transmitted to the unit 10 in (2) or (3) above, the unit 10 transmits data indicating “no stamp” to the stamp control unit 50. Upon receiving this, the stamp control unit 50 rewrites the mode data holding it to "no stamp". As a result, when the skew is detected by the punch mechanism unit, the stamp is automatically disabled (the stamp mechanism is directly passed).

(4) When both sensors 480A and 480B do not detect paper.

If both sensors 480A and 480B do not detect the paper (82a, 82b), it means that the paper has not arrived within the predetermined time, so it is a paper jam and the roller drive is stopped (82
c) Send a paper jam to unit 10 (43).

The above is the description of the A version, but when there is a punch instruction and the B version is used (77a, 78a), the sensor 42 from the sensor 478 to the register 42 in the counter 2.
Set the number of pulses for moving the paper up to 2 and set the encoder 7
30 pulses start counting down (78b), the solenoid 424 is energized (78c), the register 422 (for B5) is advanced to the paper stop position, and the arrival of paper is waited for.

If the time for the paper to move from the sensor 478 to the register 422 position has passed (81), the paper cue and paper jam detection is performed as in the A version (82a, 82b, 83a), and if it is the paper cue or the paper jam, respectively. The corresponding operation (82c, 83b) is performed. If the paper arrives in the correct posture within the given time (82a, 83a), it is the B version (8
4) Energize the steel ball solenoids 418 and 482 to pull up the steel balls 419 and 483 (86). The subsequent operation is exactly the same as that of the A version (step 87 and subsequent steps).

If there is no punch instruction (77a), the number of pulses for moving the paper from the sensor 478 to the register 422 is set in the counter 2 and the encoder 730 (Fig. 4) starts counting down the pulses (77b). Paper from sensor 478 to register 42
Refer to the paper detection status of the sensor 480A or 480B only for the time to move to the 2 position (77c, 77d), and if paper is detected within the time, it is not a paper jam and if the sensor 480A or 480B detects paper non-detection (89 ), Sets timer Ts (72), and waits for the next paper arrival (73).

When the paper is not detected within the time, it is a paper jam, so the roller drive is stopped (82c) and the paper jam is transmitted to the unit 10 (43).

Next, the control operation of the microprocessor of the stamp control unit 50 will be described with reference to FIGS. 12a and 12b.
See also Figure 8a.

First, refer to FIG. 12a. When the power is turned on, the microprocessor of unit 50 (hereinafter simply referred to as CPU)
Performs initialization (91) and state read (92). When the sensor 598A or 598B detects the paper (93), the paper jam is transmitted to the unit 10 (94).
Sensors 598A and 598B while reading the status (92)
Wait until the paper is not detected. Now, read status (92)
If the sensors 598A and 598B do not detect the paper at, refer to the detection state of the sensor 536 (95). When the sensor 536 is in the light detecting state, since the stamper's printing tool is not in the home position, the forward rotation energization of the pulse motor 520 is started and the rotation amount counting is started (96). Then, the status of the sensor 536 and the rotation amount are read (97a, 98). When the sensor 536 is in the light-shielded state, the printing tool has reached the home position and the motor 520 is stopped. Energize (97b). If the sensor 536 does not block light and the amount of rotation reaches one rotation, the motor 520 is stopped (99) and a mechanical error is sent to the unit 10 (10).
0), it waits until the power is cut off (101).

If the sensor 536 is shielded from light, then the state of the sensor 547 is referred to (102). When the sensor 547 detects light (reflector 545), the second printing cylinder 541 (printing surface of the publisher) is at the home position.

If the sensor 547 does not detect light, the issuer printing cylinder 541 is advanced by one step (103). This is done as follows.
First, the solenoid 555 is energized to advance the latch claw at the tip of the arm 553 to the base of the latch wheel 543, then the pulse motor 520 is reversed by a predetermined angle, then the solenoid 555 is de-energized, and then the pulse is pulsed. The motor 520 is forwardly biased by the predetermined angle, and a stop restraining current is applied to the motor 520.
As a result, the second printing cylinder 541 rotates 360 ° / 5 = 72 °,
This means that the printing surface has been sent by one step. Sensor 53
6 has returned to the shading state.

When such one-step printing surface feeding is completed, the feeding step counter is incremented by 1 and the count value (feeding step amount) is compared with 4 (104). If it is not 4, the state of the sensor 547 is referred to again, and if it is light-shielded, the printing surface is fed once again. In this way, the printing surface is fed step by step until the sensor 547 is shielded from light. When the sensor 547 is shielded from light, the second printing cylinder 5
41 is set to the home position (printing position is the first issuer).

If the sensor 547 does not block the light even after performing the step feed four times, it is determined that the mechanism is abnormal, the mechanical abnormality is transmitted to the unit 10 (100), and the process proceeds to the abnormality standby (101).

When the second printing cylinder 541 is at the home position, the home position determination of the first printing cylinder (drawing type printing surface) 540 is performed, and when there is no home position set, the home position set is set to the second printing cylinder.
Do the same as the home position setting of 541 (105,106,1
07).

When the first printing cylinder 540 is also at the home position, it sends ready to the unit 10 (108), waits for a signal from the unit 10 (109), and receives it from the unit 10 (110). ).

Next, proceeding to steps 111 and 112 in FIG. 12b, if the received signal is data, the data is stored in the mode register (11
3) Referring to the contents of this data (114), if the stamp is designated, the stamp-issued stamp data (first to fifth stamp numbers) and the current position (first stamp) The original mark number = 1) is compared (115), and if they do not match, the second printing cylinder 541 is step-driven (116).
The step driving operation of this step driving is step 103.
Is the same as For example, if the data designates the third printing surface, 3-1 = 2, and 2 steps are driven, and 3 is stored in the position register. When the current position is the second print surface (position register = 3) and the first print surface is specified,
Three steps are driven with 1-3 = -2 and 5-2 = 3. Next, the drawing seed mark data (the numbers of the first to fifth drawing seed marks) and the current position (the number of the first drawing seed mark = 1) are compared (117),
If they do not match, the first printing cylinder 540 is step-driven (118). This print side setting is also similar to the setting operation in step 116.

When the setting of the printing surface is completed, the ready is transmitted to the unit 10 (108), and the arrival of the start signal from the unit 10 is awaited (109, 110, 111).

When a start signal is received from unit 10, roller 58
Set 2 to the driving state, set timer Ts (119),
Refer to the paper detection status of sensors 598A and 598B (120a, 1
20b, 121a), and skew detection and jam detection (121b, 121c, 121d, 120c). The control according to the paper detection mode is as follows.

(1) When the sensors 598A and 598B are in the paper detection state at the same time.

Sensors 598A and 598B simultaneously detect paper (120
If it is a, 120b), it is normal because the paper came in the correct posture, and if there is a stamp instruction (122), set the pulse number according to the stamp position data in the counter,
The pulse of the encoder 730 (Fig. 1) is started to count down (123). When the counter reaches 0 (124), the pulse motor 520 is driven in the normal direction in synchronization with the pulse of the encoder 730, and the drive amount counting is started (125).

When the drive amount of the pulse motor 520 reaches a predetermined value PV (126),
Since the printing surface has arrived just before the roller 572, the solenoid 578 is energized (127) and the roller 572 is pulled up. This starts the stamp.

After that, the motor 520 continues to rotate in the forward direction, and when the printing tool returns to the home position, the sensor 536 is shielded from light (12
8) The motor 520 is stopped and driven, the energization of the solenoid 578 is cut off, the motor 520 is energized with a stop constraint current (129), the timer Ts is set (119), and the arrival of the next sheet is waited for. When there is no stamp instruction, the motor 520 is not energized.

(2) When sensor 598B does not detect paper, but 598A detects it.

If the sensor 598A detects paper (120a) and the sensor 598B does not detect paper (121a), refer to the state of the counter flag (121b). Since the flag is not set at first, the allowable value K is set in the counter. Then, the encoder 730 starts counting down the pulses of the encoder 730 and sets the counter flag (121c).

After setting the flag, further refer to the paper detection state of the sensors 598A and 598B (120a, 121a), and if the result is the same as before, the counter flag is set this time (121b),
Refer to the counter value (121d).

If the counter is 0 (end of K down-counting), the paper queue is transmitted to the unit 10 (121e), and the paper is fed straight through. The motor 520 required for stamping is not driven.

121d-120 until the counter counts down to 0
When the sensor 598B detects the paper within the down count of the allowable value K (121a) through the loop of a-121a-121b-121d (121a), the process exits the circulation loop instead of the paper queue and proceeds to the stamp control of step 122 and higher. That is, the same control as the above (1) is performed.

(3) When the sensor 598A does not detect the paper but the 598B detects the paper.

When the sensor 598A does not detect the paper (120a) and the sensor 598B detects the paper (120b), it is the same as the above (2).

(4) When both sensors 598A and 598B do not detect paper.

Both sensors 598A and 598B do not detect paper (120a, 120b)
In the case of, the time of the timer Ts is referred to (120c).

If the paper does not arrive and Ts times out, there is some trouble in the mechanical units up to the stamp mechanism unit 500, there is a status change such that copying is not started in the copying machine 800, the feeding is ended (end), or the paper jam Therefore, the drive of the roller 582 is stopped (120d), the standby is transmitted to the unit 10 (120e),
Proceed to status reading 92. When this process is followed, since the unit 500 is in the ready state, immediately after that, the ready is transmitted to the unit 10 in step 108, and the unit 10 waits for the start signal to arrive again.

Unless the paper arrives and the timer Ts does not expire (12
0c), the loop of 120a-120b-120c-120a is repeated until the time is over. During this time, when the sensor 598A detects the paper, it exits from the loop and the operation of (2) (120a to 121a
After that, if the sensor 598B detects paper, proceed to (3) above.
Operation (from 120b to 121b or later).

Figure 12c shows the stamped image. Of the print positions on the paper, the position from the leading edge of the paper in the feed direction is step 123.
Determined by the value set in the counter with. The printing position in the direction orthogonal to the paper feeding direction is determined by the position of the base frame 502 in the orthogonal direction. In the present invention, the paper sensor is assumed to be a reflection type so that skewed paper can be detected regardless of the paper size, but a light shielding type may be used.

In the embodiment described above, the paper is passed through the punch mechanism and the stamp mechanism when the skew is detected by the punch mechanism unit, and the paper is passed through the stamp mechanism when the skew is detected by the stamp mechanism. In the folding mechanism section as well, the skew is similarly detected, and when the skew occurs, the paper is sent out without folding processing. When skew is detected even upstream of the punch mechanism, if the skew is detected upstream of the punch mechanism, the punch mechanism and the stamp mechanism pass the paper through.

Effects As described above, according to the present invention, when fold or fold is selected in the sheet processing instruction, selection of punch and stamp addition processing is prohibited, and selection of punch and stamp addition processing is performed. If the punching or stamping process is performed, the punching or stamping process is canceled by selecting the four-folding process or the two-folding process. This is not performed, and unintended loss such as crushing of the surface image on the sheet due to the addition process is prevented.
