Description

Interleaf binding machine

The present invention relates to a slip-sheet binding machine that binds and binds a plurality of printing papers that are folded in a state in which the printing surface faces inward, and bonds them to the outer surface.

As a method of binding albums, photo books, map books, picture books, copy copies of design drawings, etc. with photos, etc., glue them to one of the outer sides of the printed paper folded so that the printing surfaces face each other, and stack them one after another A method of pasting them together is known. For example, in the interleaving machine of Patent Document 1, a plurality of vacuum rollers arranged in the vertical direction are used when pasting the folded paper after gluing, and the vacuum roller is rotated to suck the paper while rotating. The paper is always guided until the alignment. As a result, even if the paper is fed at high speed, the possibility that the paper will bounce after dropping is low, and the paper can be bonded with the edges aligned neatly. In addition, when the sheets are pressed and pressed together by a press plate, the sheets after pasting are slid onto the rails to a position where they are overlapped.

Further, for example, in the paper bi-fold gluing bookbinding apparatus of Patent Document 2, a bi-folding mechanism for folding a rectangular paper into two, a gluing mechanism for gluing the bi-fold paper, and a bi-fold paper superimposed on a base plate are provided. Using pressing means that presses and joins, the paper is folded and joined automatically. In this bookbinding apparatus, a pair of paper width regulating guides arranged in a reverse C-shape are used to guide the left and right side edges of the two-folded paper fed from the gluing roller constituting the gluing mechanism. ing. Thereby, both ears of the two origami papers that are sequentially stacked on the base plate are aligned.

Japanese Patent No. 4135923 JP 2001-187491 A

However, when printing paper is bound, the end faces of the printing paper are not aligned due to the influence of adhesion of glue on the printing paper to the rail, etc. Especially when the paper thickness of the printing paper is thin or the paper quality is soft In some cases, the printing paper fed by the vacuum roller may curl due to the feeding force of the vacuum roller when it comes into contact with the rail. In these situations, bookbinding cannot be performed properly, and appropriate measures must be taken. In addition, in the said

patent documents

1, 2, this countermeasure is not taken.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a slip-sheet binding machine capable of appropriately binding a half-fold printing paper.

The first aspect of the present invention is a slip-sheet binding machine that binds and binds a plurality of double-folded printing papers (hereinafter simply referred to as printing papers) folded so that the printing surface faces inward.
A gluing roller that rotates while gluing to one outer surface of the printing paper;
A pressure roller that rotates to form a certain gap without pressing the printing paper between the gluing roller and feeds the printing paper downward together with the gluing roller;
A plurality of suction rollers that rotate while sucking the other outer surface of the glued printing paper and feed the printing paper onto a rail;
A pair of leaf springs that contact both side edges of the printing paper to guide the printing paper to a predetermined position in the width direction and prevent the printing paper fed on the rail from bouncing back;
A printing press plate that delivers the printing paper that has been fed onto the rail to a predetermined interleaf position, and is attached to the printing paper that was previously dispensed,
The pair of leaf springs are formed by bending a thin plate spring material, and a base portion fixed to the frame, and a distance between the leaf springs with respect to the base portion in the printing paper feeding direction. And a bent contact portion formed by bending in an inclined state,
When the suction roller sends out the printing paper, the pair of leaf springs are brought into contact with both ends of the printing paper to elastically deform the pair of leaf springs, and the elastic deformation state of the pair of leaf springs is maintained. In the slip-sheet binding machine, the discharge press plate is configured to discharge the printing paper in a state where the printing paper is in close contact with the rail.

The second aspect of the present invention is a slip-sheet binding machine for binding and binding a plurality of bi-fold printing papers (hereinafter simply referred to as printing papers) folded in a state where the printing surface faces the inside.
A gluing roller that rotates while gluing to one outer surface of the printing paper;
A pressure roller that rotates to form a certain gap without pressing the printing paper between the gluing roller and feeds the printing paper downward together with the gluing roller;
A plurality of suction rollers that rotate while sucking the other outer surface of the glued printing paper and feed the printing paper onto a rail;
A pair of wires stretched vertically at positions facing the plurality of suction rollers;
Tension applying means for applying a predetermined tension to the pair of wires;
A printing press plate that delivers the printing paper that has been fed onto the rail to a predetermined interleaf position, and is attached to the printing paper that was previously dispensed,
When the suction roller feeds out the printing paper, the wire presses the vicinity of both side edges of the printing paper against the suction roller, and the dispensing press plate deflects the printing paper and the wire and the suction. The slip-sheet binding machine is characterized in that the sheet is discharged from between the rollers.

The slip-sheet binding machine according to the first aspect of the present invention uses a pair of leaf springs when binding fold-printed paper using the gluing roller, the pressure roller, the plurality of suction rollers, and the dispensing press plate. As a result, the printing paper fed onto the rails by the plurality of suction rollers is prevented from bouncing off, and when the glued printing paper is ejected by the dispensing press plate, the printing paper has excess glue on the rails. To prevent it from bouncing back. In the present invention, the printing paper refers to half-fold printing paper.
Specifically, the leaf spring of the present invention is formed by bending a thin plate-shaped spring material, and the leaf springs are fixed to the frame and the leaf springs are directed toward the feeding direction of the printing paper with respect to the base portion. And a bent contact portion that is bent and formed in an inclined state in which the distance between the two is narrowed.

When bookbinding is performed by the slip-sheet binding machine of the present invention, a two-fold printing paper is inserted between the gluing roller and the pressure roller. At this time, it is glued to one outer surface of the printing paper by the rotation of the glue roller and the pressure roller.
Then, the glued printing paper is sent out to a plurality of suction rollers, and sent out onto the rail by the plurality of suction rollers. At this time, in the present invention, the bent contact portions of the pair of leaf springs contact both side ends of the printing paper, and guide the feeding of the printing paper to a predetermined position in the width direction while being elastically deformed. Then, even after the printing paper is prevented from being rebounded by the suction roller and sent out onto the rail, the pair of leaf springs are maintained in an elastically deformed state, thereby preventing the printing paper from rebounding.

Next, the printing paper delivered onto the rail is delivered to a predetermined interleaf position by the delivery press plate, and is pasted on the printing paper delivered last time. At this time, the elastic deformation state of the pair of leaf springs in contact with the printing paper is maintained, and the printing paper receives the guide so as to be in close contact with the rail by the pair of leaf springs and is discharged to the interleaf position. As a result, even when glue that hangs down from the outer surface of the printing paper is attached to the rail, during the movement of attaching the printing paper to the printing paper previously dispensed by the dispensing press plate, the pair of leaf springs The bent contact portion comes into contact with both side edges of the printing paper, and the printing paper can be prevented from bouncing off the rail. Therefore, when the printed paper that has been dispensed last time at the interleaving position and the printed paper that has been dispensed by the dispensing press plate are pasted together, the positions of the folded edges and both side edges of the printed sheets are effectively applied to the predetermined position in the width direction. Can be aligned.

Therefore, according to the slip-sheet binding machine in the first aspect of the present invention, it is possible to effectively align the positions of the end faces and to appropriately perform the folding printing paper binding.

In the slip-sheet binding machine according to the second aspect of the present invention, particularly when the thickness of the printing paper is thin or the paper quality is soft, the printing paper is prevented from being bent when adsorbed to the suction roller. I'm doing some ingenuity.
Even when bookbinding is performed by the slip-sheet binding machine of the present invention, the two-fold printing paper is inserted between the gluing roller and the pressure roller. At this time, it is glued to one outer surface of the printing paper by the rotation of the glue roller and the pressure roller.
Then, the glued printing paper is sent out to a plurality of suction rollers, and sent out onto the rail by the plurality of suction rollers. At this time, in the present invention, the vicinity of both side edges of the printing paper is pressed against the suction roller by the pair of wires applied with tension by the tension applying means. Then, it is possible to prevent the printing paper from being bent and not being in a straight state.

Next, the printing paper delivered onto the rail is delivered to a predetermined interleaf position by the delivery press plate, and is pasted on the printing paper delivered last time. At this time, the dispensing press plate dispenses from between the wire and the suction roller while bending the printing paper. Accordingly, the printing paper can be discharged from between the wire and the suction roller without specially moving the wire and the tension applying unit. Therefore, when the printing paper dispensed last time at the interleaving position and the printing paper dispensed by the dispensing press plate are bonded together, the printing sheets can be appropriately bonded together without causing wrinkles or the like.

Therefore, according to the slip-sheet binding machine in the second aspect of the present invention, it is possible to appropriately perform the folding printing paper binding without causing wrinkles or the like.

And a bent contact portion 52 that is bent and formed in an inclined state in which the interval between the leaf springs 5 is narrowed. When the suction roller 4 feeds the printing paper 8, the interleaf binding machine 1 makes the pair of leaf springs 5 come into contact with both side ends 802 of the printing paper 8 to elastically deform the pair of leaf springs 5. While the elastic deformation state of the leaf spring 5 is maintained, the dispensing press plate 71 is configured to dispense the printing paper 8 in close contact with the rail 6.

Hereinafter, the interleaf binding machine 1 of this example will be described in detail with reference to FIGS.
As shown in FIGS. 1 and 2, the slip-sheet binding machine 1 of the present example sends the half-fold printing paper 8 downward through the gap between the gluing roller 32 and the pressure roller 33, and then in the vertical direction. It is configured to be sent downward while being suctioned by a plurality of suction rollers 4 arranged in alignment and to be placed at a receiving position on the rail 6. Also, as shown in FIGS. 4 and 5, the dispensing press plate 71 has a plurality of printing papers that are pressed against the opposing plate 72 by sliding the printing paper 8 placed at the receiving position on the rail 6 in the horizontal direction. 8 is configured so as to be bonded to the printing paper 8 that was press-contacted last time.
The interleaf binding machine 1 of this example inserts the folded end 801 of the half-fold printing paper 8 into the drum 31 first, and makes the folded end 801 abut on the rail 6 so as to align the positions for bookbinding. It is configured.

As shown in FIGS. 1 and 2, a paper stacking plate 21 is provided on the upper part of the slip-sheet binding machine 1 for storing the folded folded paper 8 in the order of pages. The paper stacking plate 21 is provided with a paper-absorbing member 22 that adsorbs the lowermost printing paper 8 one by one and takes it out downward. The paper absorbing member 22 includes two or more paper absorbing portions. Below the paper absorbent member 22, a drum 31 that receives and feeds the printing paper 8 sent by the paper absorbent member 22 from the paper stacking plate 21 is rotatably disposed. At a position facing the drum 31, a paper feed roller 34 that sandwiches and feeds the printing paper 8 between the drum 31 is rotatably arranged, and below these, the paper that feeds the printing paper 8 sandwiched and sent out. The feed rollers 34 are arranged to face each other and to be rotatable.

The gluing roller 32 is disposed below the drum 31 and the plurality of paper feed rollers 34. The pasting roller 32 is in rotational contact with the pasting roller 322 that contacts the pasting 83 in the pasting tank 321 via the pasting amount adjusting roller 323 that adjusts the pasting amount of the pasting 83.
The rail 6 provided with the pay-out press plate 71 and the counter plate 72 is configured to cope with the size change of the printing paper 8 in the vertical direction. The rail 6 can maintain the upper end of the printing paper 8 at a certain height position, and can adjust the vertical movement of the rail 6 according to the height position of the bent end 801.

The plurality of suction rollers 4 aligned in the vertical direction rotate in synchronization with each other via a rotation drive source 43, a timing belt 44, and the like, and also include a drum 31, a plurality of paper feed rollers 34, a gluing roller 32, and a pressure roller. Rotates at the same peripheral speed (feed speed) as 33.
As shown in FIG. 2, the plurality of suction rollers 4 are arranged on the left and right sides with respect to the feeding direction F of the printing paper 8. The dispensing press plate 71 is disposed so as to be slidable in the horizontal direction between the plurality of suction rollers 4. As shown in FIG. 4, on the rail 6, a counter plate 72 is provided at a position facing the paying press plate 71 so that the rail 6 is sandwiched between the upper and lower plates and the position can be held by spring pressure. The opposing plate 72 is configured to gradually retract with respect to the pay-out press plate 71 every time the printing papers 8 are pasted to keep the interleaf position 702 of the printing paper 8 at the same position.

As shown in FIG. 3 and FIG. 6, the suction roller 4 rotates and slides the cylindrical rotating part 42 formed so that a plurality of through holes 421 are arranged in the circumferential direction with respect to the outer periphery of the columnar core part 41 in which the suction passage 411 is formed. It is configured to move.
A suction pipe connected to a vacuum pump or the like is attached to the inlet of the suction passage 411 in the cylindrical core portion 41, and the outlet of the suction passage 411 is formed on the side facing the printing paper 8. Then, suction is performed by a vacuum pump or the like, and when the printing paper 8 is sent out by rotating the cylindrical core portion 41, printing is performed when the through hole 421 of the cylindrical rotating portion 42 faces the outlet of the suction passage 411. When the paper 8 is sucked and the remaining portion of the cylindrical rotating portion 42 faces the outlet of the suction passage 411, the printing paper 8 is not sucked. Thereby, it is possible to generate a suction force only at a necessary portion and to prevent a vacuum degree (suction force) from being reduced by emptying.

As shown in FIGS. 3 and 7, the pair of leaf springs 5 of the present example is fixed to the frame 2 A at the upper end side portion of the base portion 51. The pair of leaf springs 5 are configured such that the bent contact portion 52 and the portion of the base portion 51 in the feeding direction F are elastically deformed to generate an elastic deformation force when the printing paper 8 is inserted. is there. The pair of leaf springs 5 are attached to the frame 2 A using the vertical space between the suction rollers 4.

The pair of leaf springs 5 of this example are attached between a plurality of suction rollers 4 and at a plurality of locations in the vertical direction. The pair of leaf springs 5 can be brought into contact with the printing paper 8 delivered by the plurality of suction rollers 4 at one or a plurality of locations in the vertical direction.
Further, the pair of leaf springs 5 are formed in a horizontal length that guides the printing paper 8 delivered by the delivery press plate 71 to a position just before the interleaf position 702. When the feeding by the suction roller 4 and the dispensing by the dispensing press plate 71 are performed, the printing paper 8 is in contact with the pair of leaf springs 5 one by one.

As shown in FIG. 2, the plurality of suction rollers 4 and the pair of leaf springs 5 in this example are arranged with respect to the inner frame 2A arranged inside the outer frame 2B. In addition, the drum 31, the glue roller 32, the pressure roller 33, and the plurality of paper feed rollers 34 in this example are disposed with respect to the outer frame 2B.

As shown in FIG. 4, the dispensing press plate 71 waits at the retreat position 701 retracted from the plurality of suction rollers 4 until the printing paper 8 is fed onto the rail 6 by the plurality of suction rollers 4 or the like. After the printing paper 8 is sent up, the printing paper 8 is delivered to the interleaf position 702 and is attached to the printing paper 8 delivered last time held on the counter plate 72. Yes.

As shown in FIG. 7, in the slip-sheet binding machine 1 of this example, the contact of the pair of leaf springs 5 with the side edges 802 of the printing paper 8 is caused by the reaction force when the printing paper 8 is received by the rail 6. The tip of the portion 52 bites in, and the state where the biting is performed is maintained, and the dispensing press plate 71 is configured to dispense the printing paper 8 in close contact with the rail 6.
Further, the pair of leaf springs 5 is maintained in a state of being bitten into both side edges 802 of the printing paper 8 until the moment when the printing paper 8 is pasted by the dispensing press plate 71, and the folded end of the printing paper 8 on the rail 6. 801 is closely attached.

As shown in FIG. 8, the interleaf binding machine 1 of this example can bind a plurality of printing papers 8 only together, and, as shown in FIG. 9, a cardboard 80 between the printing papers 8. It is also possible to bind and bind a plurality of sheets.
For the bonding of the printing paper 8 in this example, for example, an acetic acid type emulsion type paste 83 is used. By using the thick paper 80, it is possible to improve the water absorbability of the glue 83 glued to the printing paper 8, and to make it easy to use an inexpensive acetic acid emulsion paste 83.

As shown in FIGS. 4 and 9, the rail 6 of this example has a receiving position changing unit 61 that can receive the cardboard 80 fed from the plurality of suction rollers 4 at a position higher than the upper surface of the rail 6. Yes. The receiving position changing unit 61 can move up and down via a notch hole formed in the rail 6. In FIG. 9, the upper surface of the receiving position changing unit 61 when the printing paper 8 is bonded is denoted by reference numeral 601, and the upper surface of the receiving position changing unit 61 when the thick paper 80 is bonded is denoted by reference numeral 602.

When the printing paper 8 is pasted through the thick paper 80, the slip-sheet binding machine 1 of this example pays out the thick paper 80 received by the upper surface of the receiving position changing unit 61 by the pay-out press plate 71 and puts it on the rail 6. Can be pasted on the printed paper 8 dispensed last time. As a result, as shown in FIG. 9, the thick paper 80 can be pasted at a position spaced apart from the bent end 801 of the printing paper 8 by a predetermined width, and the thick paper 80 and the printing paper 8 can be alternately stuck together for binding.

By the way, when the glued printing paper 8 is placed on the rail 6 and the glue on the outer surface 82A of the printing paper 8 adheres to the surface of the rail 6, the printing paper 8 is removed by the dispensing press plate 71. When taking out, the glue adhering to the rail 6 may become slip resistance and may cause the printing paper 8 to slip.
On the other hand, in this example, the configuration using the pair of leaf springs 5 prevents the bookbinding from being troubled by the influence of the adhesion of the glue to the rail 6.

When bookbinding is performed by the slip-sheet binding machine 1 of the present example, the folding is first performed in the gap formed by the drum 31, the plurality of paper feed rollers 34, the gluing roller 32, and the pressure roller 33, in front of the folding end 801. The paper 8 is inserted and glued to one outer surface 82 A of the printing paper 8 by the rotation of the drum 31, the plurality of paper feed rollers 34, the gluing roller 32, and the pressure roller 33.
The glued printing paper 8 is sent out to the plurality of suction rollers 4 and sent out onto the rails 6 by the plurality of suction rollers 4. At this time, in this example, the leading ends of the bent contact portions 52 of the pair of leaf springs 5 are in contact with the printing paper 8, and the printing paper 8 is fed out while being elastically deformed (between the frames 2A). To the center position). When the printing paper 8 comes into contact with the rail 6, the plurality of suction rollers 4 prevent the printing paper 8 from rebounding. Further, due to the reaction force when the printing paper 8 is received by the rail 6, as shown in FIG. 7, the leading ends of the bent contact portions 52 of the pair of leaf springs 5 bite into both side ends 802 of the printing paper 8. Thereby, the state in which the pair of leaf springs 5 is elastically deformed is maintained, and the pair of leaf springs 5 prevents the printing paper 8 from rebounding from the rails 6.

Next, the printing paper 8 delivered onto the rail 6 is delivered to a predetermined slip sheet position 702 by the delivery press plate 71 and is pasted on the printing paper 8 delivered last time. At this time, the pair of leaf springs 5 that come into contact with the printing paper 8 are elastically deformed in a state of being bitten into both side ends 802 of the printing paper 8, and the printing paper 8 receives a guide by the biting of the pair of leaf springs 5. Then, it is paid out to the slip sheet position 702.
As a result, even when the glue 83 dripping from the outer surface 82A of the printing paper 8 is attached to the rail 6, the printing paper 8 is being pasted to the printing paper 8 that has been previously dispensed by the dispensing press plate 71. 2, the ends of the bent contact portions 52 of the pair of leaf springs 5 bite into both side ends 802 of the printing paper 8, and the printing paper 8 can be prevented from bouncing off from the rail 6. Therefore, when the printing paper 8 dispensed last time at the interleaf position 702 and the printing paper 8 dispensed by the dispensing press plate 71 are bonded together, the positions of the bent ends 801 and both side edges 802 of the printing papers 8 are set. , It can be effectively aligned to a predetermined position in the width direction (a central position between the frames 2A).

Therefore, according to the slip-sheet binding machine 1 of this example, it is possible to bind the folded-printing paper 8 by effectively aligning the positions of the end faces 801 and 802.

(Example 2)
In this example, when the printing paper 8 is thin, a contrivance is made to prevent the printing paper 8 from being bent (curled) when being attracted to the suction roller 4.
Instead of providing the pair of leaf springs 5, the slip-sheet binding machine 1 of this example, as shown in FIGS. 10 to 12, a pair of wires 53 stretched up and down at positions facing the plurality of suction rollers 4, Tension applying means 54 for applying a predetermined tension to the pair of wires 53 is provided.

The wire 53 of this example is a stainless steel wire having a diameter of φ0.5 mm, and is disposed so as to be vertically stretched with respect to the frame 2A at a position facing the plurality of suction rollers 4 disposed on the pair of inner frames 2A. It is. The wire 53 is arranged in the vicinity of both side edges 802 of the printing paper 8, specifically at a position where the range within 3 mm from the side edge 802 of the printing paper 8 is pressed. Note that the position pressed by the wire 53 is more preferably 1 to 1.5 mm from the side edge 802 of the printing paper 8.

The tension applying means 54 of this example is a tension spring 54, and the tension spring 54 is attached to each of the pair of wires 53.
As shown in FIGS. 10 to 12, wire guides 55 for fixing the arrangement position of the wires 53 are provided at the upper and lower positions of the frame 2A. One end of the wire 53 is fixed to the wire guide 55 or the frame 2A, the other end of the wire 53 is attached to one end of the tension spring 54, and the other end of the tension spring 54 is fixed to the frame 2A. .
By changing the spring constant of the tension spring 54, the tension applied to the wire 53 can be adjusted to the target tension.

When the suction roller 4 feeds the printing paper 8, the slip-sheet binding machine 1 of this example uses the wire 53 that receives tension from the tension spring 54 to cause the vicinity of both side edges 802 of the printing paper 8 to the suction roller 4. It is configured to hold down. Further, as shown in FIG. 12, the slip-sheet binding machine 1 is configured such that the pay-out press plate 71 pays out from between the wire 53 and the suction roller 4 while bending the printing paper 8.
In the slip-sheet binding machine 1 of this example, bookbinding is performed using a thin copy paper (about 0.1 mm) as the printing paper 8. The thickness of the printing paper 8 can be 0.08 to 0.12 mm. The printing paper 8 may be thicker than 0.12 mm as long as the paper quality is soft.
In this example, the other configuration of the slip-sheet binding machine 1 is the same as that of the first embodiment.

When bookbinding is performed by the slip-sheet binding machine 1 of the present example, the folding is first performed in the gap formed by the drum 31, the plurality of paper feed rollers 34, the gluing roller 32, and the pressure roller 33, in front of the folding end 801. The paper 8 is inserted and glued to one outer surface 82 A of the printing paper 8 by the rotation of the drum 31, the plurality of paper feed rollers 34, the gluing roller 32, and the pressure roller 33.
The glued printing paper 8 is sent out to the plurality of suction rollers 4 and sent out onto the rails 6 by the plurality of suction rollers 4. When the printing paper 8 comes into contact with the rail 6, the feeding force by the suction roller 4 acts on the printing paper 8, and this feeding force tries to curl the printing paper 8.
On the other hand, in this example, the vicinity of both side ends 802 of the printing paper 8 is pressed against the suction roller 4 by the pair of wires 53 to which tension is applied by the tension spring 54. Then, it is possible to prevent the printing paper 8 from being bent (being no longer straight).

Next, the printing paper 8 delivered onto the rail 6 is delivered to a predetermined slip sheet position 702 by the delivery press plate 71 and pasted on the printing paper 8 delivered last time. At this time, as shown in FIG. 12, the dispensing press plate 71 dispenses from between the wire 53 and the suction roller 4 while bending the printing paper 8. Accordingly, the printing paper 8 can be discharged from between the wire 53 and the suction roller 4 without specially moving the wire 53 and the tension spring 54. Therefore, when the printed paper 8 delivered last time at the interleaf position 702 and the printed paper 8 delivered by the delivery press plate 71 are bonded together, the printed papers 8 are appropriately placed without causing wrinkles due to bending. Can be pasted together.

Therefore, according to the slip-sheet binding machine 1 of this example, the folding-printed paper 8 can be bound appropriately without causing wrinkles or the like.
In addition, the wire 53 and the tension | tensile_strength provision means 54 of this example can also be applied with respect to the slip-sheet binding machine 1 shown in the said Example 1. FIG.
