DETAILED DESCRIPTION OF THE INVENTION The present invention allows a stack of multiple sheets of paper to be folded in half-stitched, half-stitched half-folded, half-stitched half-folded, half-stitched without folding, half-stitched twice, folded twice as required.
This invention relates to a paper binding and folding machine that can perform folding and binding at a desired position, such as folding.

Generally, when making a book, a stack of multiple sheets of paper is stacked together in the center and then folded from that part, or one end of the stack of paper is stitched together and then bound together. Traditionally, paper binding machines and paper folding machines have been known separately as machines for this type of bookbinding, and since they are used separately or in succession during bookbinding, the bookbinding work efficiency has been improved. However, it has drawbacks such as high cost and large machine space requirements.

Therefore, as a result of studies in view of the above-mentioned drawbacks of the conventional art, the present invention has been developed to be able to perform paper binding and paper folding with one machine, as well as saddle stitching, center folding, flat binding half folding, flat binding double folding, flat binding double folding, A paper binding and folding machine whose purpose is to efficiently perform desired binding and folding by selecting folding only, double folding, etc. by operating a lever and a selection button, The gist is that it is equipped with a paper feed board, a paper feed claw, a paper feed plate, a paper feed stop plate, etc., and detects the stack of paper on the paper feed board to determine the paper size and desired selection. This paper is equipped with a paper feeding device that feeds paper in accordance with paper binding and paper folding positions, a stitcher, a backing die, a bending piece, a wire feed, a cutting mechanism, etc., and allows feeding paper to be selectively bound at a desired position. The function selection device is composed of a binding device, a paper folding device equipped with a folding device consisting of a torsion knife, a folding knife, and a plurality of rollers, and a function selection device for selectively operating various types of paper binding and paper folding. By operating the levers and selection buttons, each of the above devices is operated, and the desired binding and folding functions for the paper bundle are selected, so that the desired binding and folding can be performed continuously.

The present invention will be explained in detail below based on the drawings showing specific examples of implementation.

Figure 1 shows the appearance of the machine of the present invention, and as shown in Figures 2 to 1! It consists of interior decoration.

First, the paper feeding device 1 has a paper feed board 5 which is inclined as shown in FIGS. 1 and 5.
The stack of paper placed on the paper comes into contact with the paper feeding ruler 6 and the paper side edges are aligned.

The paper feed ruler 6 can be moved in the direction of arrow a shown in FIGS. 3 and 5 by a switch 8 on the operation panel 7 depending on the size of the paper to be processed, that is, the paper to be bound or folded.

That is, the paper feed ruler 6 is fixed to a guide plate 9 and two moving blocks 10, 10, and the moving blocks 10, 10 are screwed together with two moving shafts 11, 11, and the movable blocks 10, 10 are screwed together to receive the power of the motor 12. is rotationally transmitted to the moving shafts 11, 11 via a transmission mechanism such as a chain gear,
The above paper feed ruler 5, guide plate 9, moving block 10
is moved in the direction of arrow a.

The electromagnetic flange 14 is operated by a photoelectric switch 13 that detects a stack of paper placed on the father's distributing paper base board 5, and the paper feed claw 15 is moved in the direction indicated by the arrow in FIGS. 3 and 8.
It is designed to press and move the tail of the paper stack.

The paper feed board 5 receives the rotational force of the motor 16 shown in FIG. 6 through a transmission mechanism such as a belt, and is constantly rotating.When the electromagnetic clutch 14 is turned on, the rotation is controlled by the paper feed drive shaft. 17.

A total of four sprockets 19 are fixed to each of the paper feed drive shaft 17 and the paper feed driven shaft 18 (a chain is hung on each of them, and an attachment is inserted between these two chains). A passing plate 20 is attached through the
A paper feed plate 21 is fixed to the transfer plate 20, and the paper feed claw 15 is added to the paper feed plate 21 so as to be able to swing.

This paper feed claw 15 starts to move from point C shown in FIG.
The limit switch 22 is turned on at , and from then on, one of the above-mentioned illustration and folding functions is selected using a lever, switch, etc. according to the desired spelling and folding. Now let's talk about the case where you select saddle binding or folding.

By turning the limit switch 22 Oλ, the solenoid 23 shown in FIG. 8 is operated.
The details will be described later.

The transfer plate continues to move even after the limit switch 22 is turned on, and the paper feed die 15 moves to the h of the paper feed stop plate 5.
The movement of the paper is temporarily stopped at the position where it touches the part.

That is, even after the paper feed claw 15 contacts the stopped paper feed stop plate 5, the paper feed plate 21 continues to move, and the paper feed temporary 21
The paper feed pawl 15, which is rotatably attached to the paper feed plate 21, falls down in the direction of the arrow d shown in FIG. It is adapted to be locked in the f section of the locking pawl n which is resiliently biased by a spring in the direction of arrow g.

Therefore, after the paper feed pawl 15 comes into contact with the paper feed stop plate 5, it moves in a tilted state and does not push the end of the paper.

Therefore, the movement of the paper stack is stopped.

Further, in the case of saddle stitching at the paper stack stop position, the leading edge of the paper is brought into contact with the torsion knife 4 shown in FIGS. 7 and 8. (
(The bending guide 38 shown in FIG. 11 is lowered at the time of mid-folding.) The above-mentioned torsion path is supported by a moving block with the stopper shaft 4 as a fulcrum, and is supported by a solenoid mounting plate 3 fixed to the moving block. When the solenoid 32 is turned on, the displacement path swings in one direction as shown in FIG. 8 about the stopper shaft 29.
It leaves the surface through which the paper passes, and is returned by a spring 33 when it is OFF, thereby blocking the passage of paper.

The moving block member is threadedly engaged with a screw shaft 34, and the screw shirt 34 is supported by a bearing stay front 35 and a bearing stay rear 36, and a sprocket 37 is fixed to the end thereof.

The rotation of the motor 39 shown in FIG. 11 is transmitted to the connecting shaft 40 by a gear, and a chain is hung around the micro sprocket 41 fixed to the sprocket 41 and the sprocket 37, and the screw shaft 34 is driven and rotated. is adapted to move in the direction of the arrow shown in FIGS. 7 and 8.

The rotation of the connecting shaft 40 is transmitted to the feed stop adjustment shaft 42 by the sprocket and chain, and the paper feed stop plate 5 is moved in the direction of the arrow shown. Here, the screw shaft 34 and the moving pro yoke are formed with left-hand threads, and the feed stop adjustment shaft 42 and stop position adjustment block 43 are formed with right-hand threads, and paper feeding can be stopped by rotating the motor 44. The plate 5 and the torsion bar are configured to move in opposite directions (symmetrical directions) with respect to the binding position.

That is, when binding the center of the paper, the switch 8 on the operation panel 7 is operated to rotate the motor 44 in a predetermined direction depending on the size of the paper, or the knob 45 shown in FIG. 2 is rotated in a predetermined direction. The paper feed stop plate 5 is rotated to move the paper feed stop plate 5 and stop at an appropriate position.

When the father delivery claw I5 contacts the h section of the paper feed stop plate section, that is, when the tail end of the paper has been completely fed, the leading edge of the paper stops at the m section of the paper feed stop path, and at this time, the stitcher, which will be described later, stops. By performing paper binding, saddle binding is performed.

Dad, when you are not stitching the center of the paper accurately in the above-mentioned saddle stitching, you should rotate the knob 46 shown in FIG. 2 to adjust the position.

That is, in FIG. 2, the bearing 48 fixed to the side plate 47 and the center stitch vertical adjustment dial 49 are screwed together, and the knob 46
By turning the knob 46, the n part of the knob 46 is moved in the p direction, and the B IJ ring part fitted to the °C feed stop adjustment shaft 42 is pressed against the n part by the spring 50. The stop adjustment shaft, that is, the paper feed stop plate 5 is configured to move in the p direction. At this time, the distance stopper path, which is a stopper for the narrow light, is stopped, so the dimensions from the binding position to m and h are different.

Further, the paper feed claw 15 continues to move even after hitting the paper feed stop plate 5 and falling down and being latched to the locking claw 27, the Q portion of the locking claw 27 comes into contact with the release pin 51, and the paper feed claw 15 is stopped. Stopper 2
7, the paper feed claw 15 moves forward, and the switch brake plate 52 fixed to the transfer plate turns on the riminotosinch 53, causing the electromagnetic flange 14 to reach 0FFt.
, it is supposed to stop. Further, the paper feed claw 15 is configured to start from point C and stop at point C.

Here, on the substantially opposite side of the chain to which the transfer plate 20 is attached, there is provided a transfer plate force attached in the same manner as this, so that it moves in the same manner as the transfer plate addition.

Next, the case of flat binding will be explained.

When the flat binding selection button 8 on the operation panel 7 is pressed, the solenoid 54 is initially in an OFF state and the flat binding stop 55 is in a lowered state.

A stack of paper is placed on the paper feed board 5, and as described above, the electromagnetic flange 14 starts moving the ONL paper feed claw 15 from point C, and the paper feed stop @ 2 is set at a predetermined position according to the paper size.
The trailing edge of the paper is pushed forward until it comes into contact with the paper feed claw 15 force 1, but at this time, the leading edge of the paper ('!) hits the adjustment screw 56 and stops.

Turn on the limit switch 22 on the transfer plate 20, turn on the solenoid, and operate the stitcher to stitch the paper stack. The above operation is the same as the middle stitch mentioned above. (f, knee M
L, change the position where the leading edge of the paper stops. That is, when it is saddle stitched, it hits the adjusting screw 56, and when it is < n1 side stitched, it stops. ) When binding is completed, the solenoid 58 is turned on by turning on the stitch inch 57.
(Since the paper has already entered between the 10th roller 59 and the feeding roller 60), the 10th roller 59 is pressed against the feeding roller 60 to further advance the paper stack, but in the case of flat binding, there is a limit. When the switch 57 is ON, the solenoid 58 is not ONL.

In the case of flat binding, the above-mentioned transfer plate 20 is added to two chains, but the transfer plate force is added on the opposite side in the same way as the transfer plate 20, and a paper feed plate 21' is added. Fixed.

In addition, a paper feed claw 1a is rotatably attached to the protruding bin of the paper feed plate 21', and is biased by a spring 61, so that it is moved when side-stitching is completed. Now is the time to push the paper.

At this time, when the adjustment screw 56 turns on the limit switch 57 just before the binding is completed, the solenoid 54 turns ON.

so that it does not interfere with the progress of the paper.

Then, depending on the passing plate, the limit switch 22
The ONL timer is activated, and after the timer is activated, the solenoid 58 is set to O, NL, and the 10th-ra 59 is set to the feeding 0-ra 60.
and advance the paper stack. At this time, the tail end of the paper is pushed by the paper feed claw 1g so that the thin light reaches the 10th roller 59 and the feeding roller 60 point.

Turn on the above passing plate addition mint switch 22.
When the solenoid turns ON, the binding starts and the limit switch 57 turns ON. When the solenoid turns ON, the solenoid turns ON. That is, the flat stitch stopper 55 rises. Then, when the paper advances and the limit switch 62 is turned on, the solenoid 54 is turned on.
It's supposed to be FF.

Also, when the side-stitching button is pressed, the solenoid 32 is turned on.

Also, if the sheet is to be folded once after side stitching, select position 2 with -63 and the sheet will be folded and discharged along the same path as the folding after saddle stitching.

The paper binding device 2 is constructed as follows.

While the paper feed claw 15 described above moves and moves the paper,
The limit switch 22 is turned ON by the transfer plate 20.
, This turns on solenoid n.

Then, the stitcher operates and stitches the paper, but since there is a time lag from the time it starts operating until the actual stitching, the paper feed claw 15 is set at the timing to feed the paper stack until the stitcher stitches the paper stack.

A clutch piston 64 is connected to the solenoid B, the tip of which is retracted from the R surface shown in FIG. 8 when the solenoid is turned on, and protrudes when it is turned off.

A ratchet wheel 67, which is fixed to a sprocket 66 which is transmitted from a motor 65 shown in FIG. Clutch arm 69 fixed to the stitcher drive shaft above
The ratchet pawl 71 is loosely engaged with the ratchet pawl stud 70 added to the C.
(・The state of the clutch part in Fig. 8 is for the sake of explanation, and the state shown in the figure is not possible in reality.) When the solenoid 23 is OFF, the clutch piston 64 protrudes from the R surface. The S part of the ratchet pawl 71 contacts the circumferential part of the force 1 crunch piston 640, and the ratchet pawl 71 is pushed up in the direction of arrow U in FIG. 68
There is no interference with the 7th part (notches are formed at 3 places on the circumference). Also, even if the ratchet wheel 67 is rotating, the T section and the 7 section are not engaged and are stopped (. is an inverted U using the ratchet claw stand 70 as a fulcrum by the ratchet spring 72.
It is so that it is pulled in the direction. Seven portions of the ratchet wheel 67, which is constantly rotating, match and engage the T portion, so that the cruncher 9, that is, the stitcher drive shaft 68, is rotated in the same direction as the ratchet wheel 67.

When the solenoid or clutch arm 69 rotates by a certain angle, the limit switch 76 is turned on, so that the solenoid % is 0FFL and the clutch piston 64 is pulled by the spring 77 and protrudes from the R surface.

At this point, the S part of the ratchet pawl 71, which rotates with the 7th part and the T part engaged, comes into contact with the clutch piston 64, and the 7th part and the T part are engaged.
The department is moving away.

In this way, when a signal is sent from the limit switch 22, the stitcher drive shaft 68 rotates once from a predetermined position and stops at 0.degree. C. When the rotation is completed, the clutch arm 69 closes the limit switch 57. ON
L, to send the next signal.

A stitcher drive shaft is attached to the stitcher drive shaft 68, so that the stitching process can be completed in one rotation.

The stitcher section will be described below.

is designed to swing around the stud 127. Roller clutch 12 pulled by wire grip spring 128
9 is in pressure contact with the feed roller 125, and by passing the wire between them, the wire is gripped. Here, the feed roller 125 and roller clutch 129 are connected to the 12th
It is designed so that it can only be rotated in the direction of the arrow in the figure. The wire feed arm 121 can rotate about the feed arm stud 131 as a fulcrum, and its drive is transmitted to the wire feed arm 121 by a press-fit pin 132 fixed and protruding from the bending tip 95.
The ashing force is leaked from LJ by the spring 133.

The stop cam 134 is fitted onto the wire feed arm 121, and the stop cam 134 is rotated by a screwdriver or the like, and the stop cam 134 is oscillated when the Y section in FIG. It is designed to stop the movement and stop the wire feed. In other words, paper binding is not performed.

For example, if you only want to stitch in one place, it is best to set one of the two stitchers as described above.

When replacing the wire, manually insert the wire as far as the fixed blade 112 at the cutting point, but this is difficult if the roller clutch 129 and feed roller 125 are in pressure contact, so turn the stop cam 134 and insert the wire at the Y section. Kick up the shaft 123 to release it.

The wire fed to the wire reel passes through a part of the wire feeder, passes through the front side of the wire guide 136 shown in FIG. It's Nishide.

When the wire is cut by the cutting surface of the fixed blade 112,
The wire presser actuating link 117 is interlocked with the actuating link 113 and is lowered by the wire presser spring 137.
The wire is held between the presser roller 118 and the presser roller 118. At this time, the press-fitting pin 132 fixed to the bending tip 95 is stopped at the lowest position, and the wire presser operating link 117 and presser roller 11
After holding the wire between 8 and 8, the press-fit pin 132 begins to descend and the wire feed arm 121 is pulled by the return spring 133 and moves counterclockwise. At this time, the wire is moved between the roller clutch 129 and the feed roller 125. Since the mouth of the wire feed arm 1210 is held by the wire feed amount adjustment stopper 13, the wire feed arm 1210 is held in its mouth and rotates freely and does not pull the wire.
The wire feeding arm 121 swings until it hits the A part of 5, and then the operating link 113 is raised by the stitcher cam 78.
In conjunction with this, the wire presser operating link 117 also rises, and the wire clamping is released between the fixed roller 116 and the presser roller 118. After the release, the bending tip 95 is raised from the lowest position by the stitcher cam 78. Initially, the wire feeding arm 121 is rotated clockwise via the press fit pin 132.

At this time, the roller clutch 129 and the feed roller 125 both rotate in one direction, and the wire held therebetween is sent to the left together with the wire feed arm 121, thereby adjusting the wire feed amount. The striker 135 is set and fixed to the wire guide 1.36 with an eccentric stud, and by adjusting this set, the swing angle of the wire feed arm 121 is changed, and the amount of wire feed can be changed. It is.

When the wire tip is sent out from the cutting surface at the tip of the fixed blade 112, the tip 96 is brought to the lowest point by the stitcher cam 78, and the bottom surface of the tip 96 kicks up the top surface of the bending piece 108, causing the bending piece part 1 At this time, the tip of the bending piece 108 is on the extension line of the fixed blade 112, and the wire is fed from the wire cutting surface of the fixed blade 112, passing through the groove of the tip and bending. It looks like this.

At this time, the tip 96 is at the lowest point, and at the same time the bending piece I08 is kicked up, the bending piece middle plate 102 is also kicked up, and the bending piece 102 rotates around the IJ lease cam shaft 106 as a fulcrum. The grooves in the parts should now be completely open.

Therefore, the fed wire passes through the groove of the bending piece 108, is fed a predetermined length, and is then stopped.

The tip 96 gradually rises from the lowest point, and on the way, the glue part of the middle plate 102 of the bending piece is released at the neck part of the tip 96, and returns to its original position by the intermediate compression spring 104, bending the wire into the middle of the bending piece. The plate 102 is held by the bending piece 108, and then the operating link 113
descends and cuts the wire.

Thereafter, the tip 96 further rises, and the bending piece 108 is returned by the spring 109.

In addition, as shown in FIG.
08 and the concave groove core of the bending guide plate 97 fixed to the bending tip 95 are arranged so that they pass through the stable core when the bending tip 95 is lowered.

Therefore, the bending tip 95 to which the bending guide plate 97 is fixed gradually descends from the highest point, wraps the stable into the grooves of the two bending guide plates 96 on both sides, and bends the stable into a mouth shape. .

Father, while the bending guide plate 96 is descending, the release cam 10
5 is rotated around the cam shaft 106 as a fulcrum, and the protruding part of the middle plate group 2 of the bending piece is pushed by the IJ IJ-scum 105, so that the part is hooked to the waist part of the IJ IJ-scum. . That is, the stable held by the middle plate 102 of the bending piece is released.

Then, the bent tip 95 is completely lowered (at this time, the wire feed arm is moved back) so as to hold down the bundle of paper to be bound.

Next, the tip 96 begins to descend, and the bending piece 108 is kicked by the tip plate 9' fixed to the tip 96, and rotates about the shaft 101 as a fulcrum. That is, the stable is removed from the corner of the bending piece 108 and the bending guide plate 9
The stable is supported by the mouth mold only in the groove 7, and the stable is pressed down by the protruding plate 96a and thrust into the paper, and the above-mentioned clincher operates to flatten the back of the binding.

Here, when the tip 96 descends, the bending piece middle temporary 102
σ) Kick the edge part slightly to release the latch on the other part.

Although one cycle of binding has been described above, the actual beginning is when the bent cusps 95 and 96 rise slightly after the binding is completed.

Next, the paper folding device) will be described.

When the stitcher drive shaft 68 completes one rotation and the limit switch 57 is turned on, the solenoid 32 releases the stopper of the ONL adjustment stopper group, and at the same time, the solenoid 58 turns ONL and the limit switch 57, which is rotating at the same circumferential speed as the feed roller 60.

The 20th roller 162 is constantly rotating in the direction of the arrow, and when the folding roller 158 is pressed against the 20th roller 1aσ, the paper stack is sandwiched between the folding roller 158 and the 20th roller 199, A stack of paper is sent between the 10th and 959th stations.

The Toi No. 20-ra 1B9 and the feeding roller 6o are rotating in pressure contact with each other, so that a stack of paper can be fed from either side.

For example, in the case of folding one or more sheets of paper, the state without the folding mirror roller 158 and the folding knife 153 is sufficient.

In other words, the first roller 59 presses against the feed roller 6o to feed the paper, and the tenth roller 59 and the feed roller 60 continue to feed even if the left side of the folding stopper 163 is illuminated by a thin light.

Since the narrow light is stung at the left part above, there is no escape, so the paper curls in the space y part under the 20th line 18σ and the 10th line 59, so it is recorded as it gradually increases in size. 1st. It is folded by being caught between the second rollers 59 and 189.
