DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat stitch book or a saddle stitch book such as a book, a magazine, etc., in which a binding portion is formed by using a thread at one end or one or several places along a straight fold portion of a sheet. The present invention relates to a binding such as a booklet such as a catalog and an apparatus for manufacturing the binding.

[0002]

2. Description of the Related Art As a conventional sewn material, a sewn stitching method is used in which a sewing thread is used to sew continuously along one end of a superimposed sheet (such as a signature) or a straight fold line with a sewing machine. There are things. In addition, there is a stapled stitched by a wire stitching device (stitcher) using a wire (stitch) intermittently along one end of a superimposed sheet (such as a signature) or a straight line fold. . Further, the adhesive (such as glue, hot melt adhesive or the like) is continuously or intermittently applied along one end or straight line of the overlapped paper (such as a signature) without using the binding thread or wire. Glue) is applied and bound by an adhesive binding device. In addition, a combined stitching method using a combination of any two of the above-described sewing stitching method, wire stitching method, and adhesive stitching method is known.

[0003] A technique disclosed in Japanese Patent Application Laid-Open No. 7-46788 is disclosed in which an inverted U-shape is inserted from one side to the other side at two locations along one end of a superposed sheet. The binding section is formed by joining both ends of the binding thread to each other.

[0004]

Among the above binding methods, binding materials such as books, magazines, catalogs, etc., bound by the wire binding method must be separated into paper and wire when discarded. In addition, a binding material formed by using a binding thread without using a wire has an advantage that it is relatively easy to dispose.

[0005] However, in the case of binding a book, a magazine, a catalog or the like using a binding thread, bookbinding is performed by a sewing machine binding device. It is easy to continuously bind the thread along one end or the straight fold, but it is difficult to perform the thread binding operation intermittently. There is a drawback that fraying easily occurs.

The present invention relates to a binding material capable of intermittently performing a thread binding operation along one end of a sheet (such as a signature) or a straight fold. An object of the present invention is to enable bookbinding of a binding material such as a catalog.

In the technique disclosed in Japanese Patent Application Laid-Open No. 7-46788, an adhesive is used for joining yarns.
At the time of disposal, it may be a problem whether or not the material of the adhesive generates harmful substances. Considering the reuse of waste paper and the like, the yarn itself is cellulose, which is not a problem, but the resin used for the adhesive is mainly water-insoluble and it is difficult to recycle the waste paper together with the waste paper. is there. Further, the resin used for the spelling may harden a hand or the like due to a hardened and broken tip. If the resin used for bonding is not completely cured and maintains a certain viscosity, the resin may adhere between the booklets, or the booklets may be packaged, resulting in a commercial value of the booklets. Is reduced.

[0008]

In order to solve the above problems, the present invention uses the following means. As described in the first aspect, a signature or a sheet is stitched by two opposed saddle stitch machines.

According to a second aspect of the present invention, the position of the saddle stitching machine disposed at the opposed position can be adjusted in a direction perpendicular to the conveying direction via a conveying machine.

According to a third aspect of the present invention, two portions of the back portion of the booklet are stitched together.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a conceptual diagram showing a booklet manufacturing configuration, FIG. 2 is a perspective view showing a configuration of a bookbinding apparatus, FIG. 3 is a plan view of the same, FIG. 4 is a conceptual diagram showing a signature conveying direction, and FIG. FIG. 6 is a side view showing the configuration of the saddle stitching machine, FIG. 7 is a side view of the saddle stitching machine showing the mounted state of the holding device, FIG. 8 is a front view thereof, and FIG. FIG. 10 is a side view of the saddle stitching machine showing another configuration of the apparatus.
FIG. 7 is a perspective view showing another configuration of the bookbinding device.

First, a booklet and a method of manufacturing the booklet according to the present invention will be described with reference to FIG. The sheet 1 is folded by a collating machine to form a signature 2. Signature 2 is fed flat,
The sewing machine simultaneously binds the two portions on a straight line that bisects the signature 2. Thereafter, a line is linearly pushed so as to coincide with the two sewing locations A and B of the signature 2. Then, the sewn portion is folded in two with the sewed portion as the upper side. Further, the edges 3 and 4 of the signature 2 not including the sewing location of the two signatures are cut. With this, the two places are stitched,
You can get a booklet. Since the booklet is stitched at two places, the stitching time is short, and since the paper sheets are joined by the main stitch, the durability is high. The number of times the needle moves up and down for suturing and the suturing interval are adjustable.

The above booklet is bound only with a thread and does not use any other adhesive or the like. In the above configuration, the booklet is sewn to a signature. However, it is also possible to stack a plurality of sheets, align and position the sheets, and then bind one or more places with a thread. The signature and the paper are sewn from the back of the booklet. As a result, the end of the thread used for sewing is inside the booklet, and is protected by the booklet when the booklet is conveyed or packed, so that the booklet is not easily frayed. Further, when the booklet is closed, the ends of the thread are located inside the booklet, so that the appearance is neat and aesthetically pleasing. When the sewing needle penetrates, the burrs formed on the paper leaf can be formed inside the booklet, so that the appearance is not impaired. The woven fabric of the present invention is sewn from the outside to the inside, and the cut end of the thread is held inside when the book is put in a booklet state.

Since the booklet is sewn at two places at the same time, a deviation between sheets is less likely to occur at the time of thread binding. The same applies to the case where a signature is bound and the case where a plurality of sheets are bound.
Since two locations are simultaneously bound, the position of the paper sheet is fixed by the two sewing needles, and no deviation occurs. When a plurality of locations are bound, two locations are first bound simultaneously, and then the other locations are bound. Thereby, a booklet without deviation can be constituted. Furthermore, since two places are sewn at the same time, the time required for booklet production can be reduced.

Next, the configuration of the bookbinding apparatus for manufacturing the booklet will be described with reference to FIGS. Bookbinding device 1
0 is a collating machine 11, a transporting machine 12, a saddle stitching machine 13,
Conveyor 14, streak pushing machine, folding machine 16, press machine 1
7 and an accumulator 18. The sheet is folded by the collating machine 11 to form a signature. The signature is supplied to the saddle stitching machine 13 by the transport device 12. The signature continuously supplied from the collating machine 11 stops at one position between the saddle stitching machines 13 and 13 and is sewn by the saddle stitching machines 13. The saddle stitching machine 13 is disposed so as to oppose the conveying machine 12 therebetween. That is, the two saddle stitching machines 13 are arranged symmetrically with respect to the transporter 12 so that their sewing needles are located at the center of the transporter 12.

The signatures sewn by the saddle stitching machines 13 are sent to a transfer machine 14, and are passed through a line pushing machine 15, a two-fold machine 16 and a press machine 17 connected to the transfer machine 14.
It is integrated in the accumulator 18. Transfer machine 14
The signature supplied to the line pushing machine 15 is the line pushing machine 1

As the streaking press 15, one using a pair or two or more pairs of a convex roller and a concave roller to form a streak on a signature, a stamping device using a convex plate and a concave plate to form a streak, and the like are used. be able to.

Then, the signature is folded by the two-folding machine 16 so that the streaks inserted into the signature become the back part. The two-folding machine 16 includes a pair of rollers arranged in parallel with the line direction of the signature, and an arm for introducing the signature into the rollers. The signature supplied to the two-folding machine 16 is located above the arm, and the signature is introduced into the rollers by raising the arm. The arm is formed in a flat plate shape, and is configured to contact the position of the line of the signature from below. For this reason, the signature is introduced into the roller with the streaked portion locked by the arm. The roller is rotated so as to rotate upward on the inside, and the signature introduced into the roller is wound around a pair of rollers from the portion pressed by the streak and folded into two.

The signature folded in two is introduced into a press 17 and pressed by a pair of presses 17, 17 symmetrically arranged with respect to the carrier 14, and the signature is bound to an accumulator 18. Is to be stocked. A device for cutting the edge of the signature is provided in a process after the press machine 17,
After the signatures are cut, the signatures can be stocked in the stacking machine 18.

In the above configuration, the two transporting machines 12 connected to the saddle stitching machine 13 are connected to the transporting machine 14.
Is connected. As a result, the time required for sewing one signature can be reduced, and productivity can be improved. Further, since the signature is fed flat, the signature can be transported by a simple transporter. A transport machine 12 for supplying signatures sewn from the saddle stitching machine 13 to the transport machine 14.
Reference numeral 12 is disposed at a right angle in plan view. For this reason, a plurality of saddle stitch machines 13
In this method, a large number of signatures can be sewn by connecting a signature suturing mechanism in which the two are combined. Thereby, the time required for manufacturing can be reduced.

Next, the flow of the signature will be described with reference to FIG. In FIG. 4, the signature 2 is moved right and left
And stitched by the saddle stitching machines 13. Thereafter, the sheet is conveyed in the up-down direction by the conveying machine 14. Then, the streaks are passed through the streak pushing machine 15, and are folded in half by the two-folding machine 16. Here, the signature sewn on the transporter 12 is
4 transports in the sewing direction (vertical direction in FIG. 4). Then, line pushing and folding in two are performed in parallel with the transport direction. Since the line is pushed and folded in parallel with the transport direction, even if the signature is displaced in the transport direction, if the left and right positions match, the stripe can be pushed to the stitching position and folded in two. Things. Thereby, the manufacturing accuracy of the booklet can be improved.

Further, the saddle stitching machine 1 is
The conveyors 12 for feeding the sewn signatures from 3 are arranged at right angles in plan view. Since it is connected to the conveyor 14 at a right angle, the overall length of the production line can be shortened, and the production line for the saddle-stitch booklet can be made compact.

Next, the configuration of the saddle stitching machine 13 will be described. As shown in FIGS. 5 and 6, the saddle stitching machine 13 is disposed on the side of the transporting machine 12.
2, two units facing each other are provided. The saddle stitching machine 13 is installed on a table 21 and slidably disposed on a rail 22 attached to the upper part of the table 21. Needless to say, the saddle stitching machine 13 can be fixed to the table 21, and can be slid to an arbitrary position and fixed. Wheel section 23 is provided at the lower portion of saddle stitching machine 13.
The wheel portion 23 is provided with a plurality of wheels, and is configured so that the saddle stitching machine 13 can slide smoothly along the rail 22. Thus, the position of the saddle stitching machine 13 with respect to the transporter 12 and the position of the needle 25 can be adjusted to adjust the sewing position of the signature.

A pulley 28.2 is provided at the rear of the saddle stitching machine 13.
The power is transmitted to the saddle stitching machine 13 by the rotation of the pulleys 28. A timing belt 29 is wound around the pulleys 28 and 28 and the pulleys 30 and 30.
Numeral 30 is inserted and fixed to the driving force transmission shaft 27. The driving force transmission shaft 27 is connected to a motor or the like, and transmits the driving force of the motor to the saddle stitch machine 13 via the driving force transmission shaft 27 and the timing belts 29.

As the saddle stitching machine 13, one having an automatic lower thread supply device 24 is used. This automatically performs a series of operations associated with bobbin thread replacement, such as removal of a bobbin, mounting, removal of remaining thread, thread winding, thread setting, and thread cutting. The lower thread automatic supply device 24 is not particularly limited as long as it can automatically replace the lower thread. For example, by using a sewing machine described in Japanese Patent Application Laid-Open No. 2000-5777, even a bookbinding apparatus that supplies signatures by flat feed can continuously perform a stitching process without interrupting the work. It is.

It is also possible to attach a holding device for suppressing signatures to the saddle stitching machine 13. As shown in FIG. 7, a holding device 34 is provided upstream or downstream of the needle 25 in the signature transport direction. Since the saddle stitching machine 13 is located at a position opposed via the transporter 12,
By disposing the holding device 34 on the side of the needle 25, the adjustable range of the interval between the saddle stitch machines 13 can be increased. A stay 33 is fixed to the holding device 34, and an arm 32 connected to the air cylinder 31 is connected to the stay 33. The arm 32 is rotatably supported at the center of the saddle stitching machine 13,
The holding device 34 is moved up and down via the stay 33 by expansion and contraction of the air cylinder 31. Thereby, when the signature is supplied to the saddle stitching machine 13, the holding device 34 can be moved downward, the signature can be held, and the signature can be stitched reliably. The holding devices 34 are arranged above and below the signature, and the signatures can be sandwiched by the holding devices 34 to more reliably perform positioning.

The structure of the holding device 34 is as follows. First of all, simply hold the signature by vertical movement. Alternatively, as shown in FIG. 8, a belt 38 is provided in parallel with the signature conveying direction, and the belt 38 is driven to adjust the position of the signature or to send the sewn signature in the conveying direction. In this case, the holding device is constituted by pulleys 36 and 37, a belt 38, and a motor 39.
9, the pulley 37 is driven, and the belt wound around the pulleys 36 and 37 is driven.

As a third example of the holding device 34, as shown in FIG. 9, the belt 43 is arranged so that the conveying direction of the signature is at right angles, and the signature is conveyed before, after or at the time of sewing. It is driven in a direction perpendicular to the direction. In the case of driving in the right angle direction before the sewing, if the supply position of the signature supplied by the transporter 12 is different from the sewing position, the signature is moved to the sewing position, and the signature is driven in the right angle direction after the sewing. In such a case, the signature is moved to the transport position when the position where the sewing is completed by the saddle stitching machine 13 and the supply position where the signature is transported downstream by the transport device 12 are different. Driving the signature in a direction perpendicular to the suturing operation is performed when the suturing of the signature is performed over a wide range. By suturing the signature supplied to the saddle stitching machine 13 while moving the signature to the right or left with respect to the conveying direction of the signature,
Long distances can be sutured. Since the sewing position of the saddle stitch machine 13 is fixed, it is not necessary to change the sewing position of the saddle stitch sewing machine 13 by moving the signature to the left and right.

In the bookbinding apparatus 10, the transporter 12
Another embodiment will be described. In FIG. 10, a rail 51 parallel to the transport direction is mounted on the upper part of the transporter 12, and a signature holder 52 is mounted on the rail 51. The signature time 52 is configured to be slidable along the rail 51, so that the signature supplied to the transport device 12 can be supplied to the saddle stitching machine 13 and thereafter to the transport device 14. Things. Alternatively, in the transporter 12, the sheet may be transported to the saddle stitching machine 13 by a belt conveyor or the like provided below the rail 51, and the saddle-stitched signature may be supplied to the transporter 14 by the signature holder 52. It is possible. In the transporter 12, the saddle stitching machine 13 is
Does not affect the configuration of the lower part of the. As described above, the lower thread automatic supply device 24 is provided below the saddle stitching machine 13. For this reason, the configuration of the lower portion of the saddle stitching machine 13 is complicated, and the space for disposing the transport device is limited. However, the rail 51 is located above the transporter 12.
And a signature holding device 52 locked to the rail 51.
By transporting the signature, the configuration of the transporter 12 can be simplified.

In the configuration of the embodiment of the present invention, the signature can be replaced with a sheet in which paper sheets are superimposed, and what is described as a belt can be replaced with a timing belt. The air cylinder may be a hydraulic cylinder. Further, the transporter 12
In the above configuration, it is also possible to lock the two signature holding devices 52 and 52 on the left and right sides of the rail 51 so that the signatures are alternately conveyed by the signature holding device 52.
