Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle stitch bookbinding apparatus, a gluing nozzle unit and a signature holding member used therefor, and a saddle stitch book binding method, and in particular, a gluing nozzle that can be added as an attachment to an existing saddle stitch bookbinding apparatus. The present invention relates to a unit, a signature holding member, a saddle stitch book binding apparatus in which such a member is incorporated, and a saddle stitch book binding method.

  2. Description of the Related Art Conventionally, printed materials, particularly saddle-stitched books, are manufactured by performing three-side cutting after binding stacked signatures with a wire. For example, a bookbinding apparatus for saddle stitch book described in Patent Document 1 is a conveyance rail for hanging stacked signatures and pushes the signature in contact with an upstream side of the signature hooked on the conveyance rail. And a chain that travels along the transport rail, a slider that runs parallel to the transport direction of the chain above the transport rail, and an actuator that moves the stitcher head mounted on the slider back and forth in the transport direction of the chain. is doing.

  The saddle stitch bookbinding apparatus described in Patent Document 1 has the following operation. The signature hung on the transport rail is pushed on the transport rail when the pusher of the chain comes into contact with one side of the upstream side. Since the dimensions before and after the three-way cutting, that is, the paper edge dimension of the back portion of the signature and the paper edge dimension of the back portion of the finished printed matter are known, a control means is provided in the apparatus, and the predetermined size is determined in advance from the paper edge dimension. Calculate the dimensions. The predetermined dimensions are mainly a cut-off dimension of one side on the upstream side of the signature and a paper-end-side wire driving dimension from the upstream paper end of the back portion of the printed matter to the saddle stitching position of the wire.

Since the signature is pushed by the pusher, a stitcher head for driving the wire to the back portion of the signature is arranged at a predetermined position downstream of the pusher by the cut-off dimension and the wire driving dimension. The stitcher head is mounted on a slider that runs parallel to the chain, and drives the wire into the signature being fed by the pusher. The slider is reciprocated in the chain conveyance direction by a crank piston mechanism or by a chain provided separately from the conveyance chain.

The signature in which the wire is driven is unloaded from the chain and cut in three directions. By using the pusher for pushing the signature and arranging the stitcher head with reference to the pusher, the wire can be driven accurately and easily.

  On the other hand, the one described in Patent Document 2 that solves the problems found in the saddle-stitch bookbinding device described in Patent Document 1 by not using a wire or a staple is provided with a cut sheet facing down (inside down). Then, the sheets are fed one by one from the cover in the order of the main body, and are accumulated until the specified number of sheets is reached while applying the paste to the center line of the cut sheet, except for the final sheet, by the nozzle controlled by the sensor. Using a line as a crease, press the line glue part while folding it in two to bind it to a book.

  The saddle stitch bookbinding apparatus described in Patent Document 2 has the following operation. In other words, this machine cuts the cut paper or continuous paper printed by various printers linked with the computer and turns the cut paper upside down and sends it in the order of the cover page → the text in the center line → collation → Integrated bookbinding with the printer is possible by folding in half → press. In addition, by reading the marks printed on the paper using a sensor, it is possible to bind a book with a random number of pages printed with individual data, a book with a different number of pages or a number of books, and a small amount of books, which was difficult with the prior art. On the other hand, this device is useful.

Japanese Patent Laid-Open No. 09-048184 Claim 1 Japanese Patent Laid-Open No. 11-301137.

However, in the case of using a wire or staple that is represented by the saddle stitch bookbinding apparatus described in Patent Document 1, the legs of the wire are exposed from the paper and the reader's finger is damaged, or the paper is used from the wire. There was a defect that it would come off. Further, when making recycled paper after disposal, a step of removing the wire is necessary, or even when landfilling is performed, leaving the wire is not preferable in terms of environmental protection.
On the other hand, in the saddle-stitch bookbinding apparatus described in Patent Document 2 that does not use a wire, it is impossible to prevent the wire paste from meandering due to the vibration of the cut paper conveyed on the conveyor. There was a drawback that a trace of glued waves was created at the back of each page.
In the prior art, there is no apparatus of a type that binds a saddle-stitched book by applying glue to the hook signature. The glue could not be applied in a straight line along the top line of the signature that was slid and conveyed on the conveyance rail. This is presumed to be because it was not possible to prevent an accident that the glue was not positioned well on the back side of the top line of the signature where the glue was piled up and adhered to the printed part.

The present invention relates to a glue nozzle unit that applies glue in a straight line along the top line of a hook signature that is slid and conveyed on a transport rail, and the back side of the top line of the signature on which the glue is stacked when the signature is stacked and bonded. The above-mentioned problems of the prior art have been solved by developing a jig that can be positioned in a good position.
The present invention relates to a saddle-stitch bookbinding apparatus and a middle-stitch bookbinding device in which the legs are exposed from the paper and the reader's finger is not damaged by using no wire or staple, and the paper does not come off the wire during use of the book. It is an object of the present invention to provide a binding method for binding books.
Another object of the present invention is to provide a gluing nozzle unit that can apply glue in a straight line along the top line of a hook signature that is slid and conveyed on a conveyance rail.
Another object of the present invention is to provide a signature holding member that can be positioned well on the back side of the top of the signature on which the glue is superimposed when the signatures are stacked and bonded.

In order to solve the above-mentioned problem, the first invention of the present application described in claim 1 is to sequentially stack the next signatures at a plurality of signature stacking positions and convey them to the arrangement position of the stitcher head and further to the bookbinding discharge position. A transport rail that slides and conveys the signature, and a pusher that contacts the rear side in the advancing direction of the hook signature that is hung on the transport rail and pushes the signature and travels along the transport rail And a stitcher head that is placed above the transport rail and lays the wire into the final stacked signature formed by stacking the last signature, and the finished stacked signature that has been driven from the bookbinding discharge position. In a saddle stitch bookbinding apparatus including a cutting section that cuts three-sided except for a portion, the top of a signature positioned before and after the position where the adhesive is applied in the traveling direction of the signature before the signature stacking position. Both lines A glue nozzle unit that applies glue to the back of the signature in a straight line while pressing toward the transport rail from above, and the next folding that is arranged and fed above the transport rail at the signature stacking position. Holding a signature, when the hook signature is pushed and moved by the pusher of the transport means, the next signature that is held is also pushed together and dropped on the glued signature signature Two long plate members are connected so as to form a predetermined angle at the top line, and the leading side in the direction of travel of the signature is cut at an acute angle from the bottom to the top line A saddle stitch bookbinding apparatus is provided, which is provided with a signature holding member .
In an existing or newly produced saddle stitch bookbinding device, by providing a gluing nozzle unit, it is possible to book a saddle stitch book by wire or staple, or to bind a saddle stitch book by gluing. Become. When a gluing nozzle unit is added to an existing bookbinding apparatus, it is possible to detect various functions of the existing saddle stitch bookbinding apparatus, for example, dropping of a signature by a sensor. This makes it possible to bind a saddle stitch book by gluing without a defective product such as a missing page with the addition of a minimum function.
Further, the next signature to be supplied is held above the conveyance rail at the signature stacking position, and the next signature held when the hook signature is pushed and moved by the pusher of the conveyance means. Is also provided with a signature holding member that can be pushed together and dropped onto the hook signature. The signature holding member holds the signature to be stacked next above the conveyance rail at the signature stacking position. And when the hook signature is pushed and moved by the pusher of the conveying means, the next holding signature can also be pushed together to release the holding state and drop onto the hook signature It becomes. In addition, the signature holding member can reliably hold the signature to be laminated next on the back side of the top line. Furthermore, at the moment when the next signature is dropped from the signature holding member by being pushed by the pusher of the conveying means, the last line of the top line of the signature forms an arc centering on the leading edge already falling on the hook signature. Draw and fall. At this time, the next signature can be successfully placed on the hook signature without colliding by the sharp cut formed on the leading side of the signature holding member in the traveling direction.

In order to solve the above-mentioned problem, the second invention of the present invention described in claim 2 is configured to sequentially stack the next signature at a plurality of signature stacking positions, and slide and convey the signature to be transported to the bookbinding discharge position. In front of the stacking position, the transporting means includes a transporting rail, a transporting means that travels along the transporting rail, and includes a pusher that abuts on the rear side in the traveling direction of the hooked signature hung on the transporting rail and pushes the signature. A glue nozzle unit that applies glue to the top line of the signature on the back of the signature, and the next signature to be fed is held above the conveyance rail at the signature stacking position. A signature holding member that, when moved by the pusher of the means, moves the next signature held together and drops it onto the hook signature, and the glue that is discharged from the bookbinding discharge position. Completed finished signatures except for the back In the bookbinding apparatus of the binding present in that comprising a cutting section for three-way cutting, gluing nozzle unit, conveying both sides of the top line of the signature to be located before and after the application position of the adhesive in the travel direction of the signature from above It is configured to apply glue in a straight line to the back part of the signature while pressing toward the rail side, and the signature holding member is configured so that the two long plate members form a predetermined angle at the top line. Provided is a saddle stitch bookbinding apparatus characterized in that the leading side in the traveling direction of a signature is formed with an incision at an acute angle from the skirt toward the top line .
The difference from the first aspect of the present invention is that a gluing nozzle unit is provided in the stitcher head removed. Therefore, in the case of the second invention, the saddle stitch book cannot be bound by wire or staples, and only the saddle stitch book can be bound by gluing.

In order to solve the above-mentioned problem, the invention according to claim 3 is the saddle stitch bookbinding apparatus according to claim 1 or 2, wherein the gluing nozzle unit is placed on the transport rail and is rearward by the transport means. A glue nozzle that attaches adhesive to the back of a hook signature that is slid when the side is pushed, and a glue nozzle that detects that the hook signature has moved to a predetermined position and discharges glue. A roller guide disposed before and after the glue nozzle in the direction of travel of the signature and a sensor provided, and both sides of the back of the hook signature placed on the transport rail from the upper side toward the transport rail And a roller guide for pressing.
The glue nozzle detects that the signature has moved to a predetermined position based on a signal from the sensor, and discharges glue. The sensor arrangement position may be provided close to the conveyance rail or close to a signature holding member described later. Of course, both can be provided. The hook signature is slid while the rear side is pushed by the conveying means. However, at the portion where the gluing is performed, the both sides of the spine are pressed from above by the roller guide. Therefore, the signature is suppressed from meandering, and as a result, the glue nozzle can apply the adhesive in a straight line to the back portion of the hook signature. The speed in the tangential direction at the contact point between the roller guide and the signature can be made substantially the same as the moving speed of the conveying means.

In order to solve the above-mentioned problem, the invention according to claim 4 is the saddle stitch bookbinding apparatus according to claim 3, wherein the roller guide has a groove having a V-shaped cross section on the outer peripheral surface thereof. Features.
Even when the roller guide is slid by the rear side being pushed by the conveying means and the hook signature is glued along its top line by the glue nozzle, both sides of the roller guide can be pressed from above. .

As described above, according to the present invention, since a wire or a stapler is not used, the disadvantages due to these are eliminated.

The saddle stitch bookbinding apparatus according to the present invention will be described in more detail based on the embodiments.
As shown in FIG. 1, the saddle stitch bookbinding apparatus 10 according to the present invention generally includes a first signature stacking position F1, a second and subsequent signature stacking positions Fn, that is, It consists of a gluing nozzle unit N, a stitcher head arrangement position S, a bookbinding discharge position T1, and a cutting portion T2 provided in front of the stacking position where the next signature is stacked. From the right side to the left side of the figure, each signature stacking position Fn is sequentially released onto the transport rail 12 from the signature 14 that is the inner side when bookbinding. The transport rail 12 sequentially stacks the next signatures at a plurality of signature stacking positions, and transports them to the stitcher head placement position S and further to the bookbinding discharge position T1. The dropped signatures 14 are pushed and conveyed by the gathering chain 16 toward the left side of the figure while being sequentially stacked. The gathering chain 16 includes a pusher 26 that abuts against the rear side of the signature 14 that is hung on the conveyance rail 12 and pushes the signature. At the stitcher head arrangement position S, the wire 18 is driven into the final signature 14, that is, the completed signature that is completed by stacking the signature 14 that is the outermost side when bookbinding. At the bookbinding discharge position T1, the direction of the completed laminated signature unloaded from the gathering chain 16 is changed. In the cutting part T2, three-way cutting of the completed laminated signature is performed. That is, the cutting part provided in this part performs three-way cutting except for the back part.

The gathering chain 16 is suspended between the drive sprocket 20 and the driven sprocket 22. The angle phase of the drive sprocket 20 with respect to the drive shaft 24 can be adjusted. The drive shaft 24 is driven via a gear and a shaft from a motor (not shown). The signature pusher pusher 26 is fixed to the gathering chain 16 at equal intervals, and stands above the carrier rail 12. The signature 14 is dropped from the paper feeder 28 onto the transport rail 12 and suspended in a reverse V shape with the back portion facing upward (this state is also referred to as “saddle signature”). The hook signature 14 is pushed and conveyed by a pusher 26.
The saddle stitch bookbinding apparatus 10 according to the present invention is characterized in that between the signature stacking position F and the signature stacking position F, both sides of the top line of the signature are conveyed from above to the back portion of the signature 14. This is the point that a gluing nozzle unit N that applies gluing in a straight line while pressing against the rail 12 is provided.

As shown in detail in FIG. 3, the glue nozzle unit N is mounted on the conveying rail 12 and adhered to the back portion of the hook signature that is slid by the rear side being pushed by the gathering chain 16. A paste nozzle N1 for applying the agent, a sensor N2 provided in association with the paste nozzle for detecting that the signature has moved to a predetermined position and discharging the paste, and a front and rear direction of the paste nozzle N1. A pair of roller guides N3 is included. In the preferred embodiment shown, the sensor N2 is a place where it can detect that the hook signature 14 is placed on the transport rail 12 and the rear side is pushed by the gathering chain 16 and slides to a predetermined position. Is installed. In the preferred embodiment shown in FIG. 5, a sensor N4 is further provided adjacent to the cut-in H2 side of the signature holding member H. This is because when the signature 14 to be stacked next falls on the signature holding member H and falls down at the signature stacking position, it is definitely detected. When any one of the sensors N2 and N4 generates a signature non-existence signal, the glue is not discharged from the glue nozzle N1.

The roller guide N3 presses both side portions of the back of the hook signature placed on the transport rail 12 from above, and has a V-shaped groove on the outer peripheral surface thereof. The roller guide N3 can be an idle roll, but can also be synchronized with the moving speed of the gathering chain 16. That is, the tangential speed at the contact point between the roller guide N3 and the signature 14 is substantially the same as the moving speed of the gathering chain 16. This is to prevent a gap between the stacked signature 14 and the hook signature.
At each stacking position Fn, in order to accurately stack the hook signature placed on the transport rail 12 and moved forward and the next signature 14 to be stacked at that position, The second feature of the saddle stitch bookbinding apparatus 10 according to the present invention is that the signature holding member H that holds the signature 14 is provided above the conveyance rail 12 at the signature stacking position Fn. The signature holding member H holds the next signature 14 that can be pushed together when the hook signature is pushed and moved by the pusher 26 of the gathering chain 16. Then, the next signature advances and tilts out of the signature holding member H, and finally falls off the signature holding member H and drops onto the hook signature.
In the illustrated preferred embodiment, the signature holding member H is formed by connecting two long plate members H1 so as to form a predetermined angle with the top line, and the leading side of the signature in the traveling direction is a skirt. A sharp cut H2 is formed from the top toward the top line. This prevents the next signature 14 from coming into contact with the rear end of the signature holding member H when the signature 14 is dropped from the signature holding member H and dropped onto the hook signature. Therefore, the signature 14 is laminated on the hook signature in a clean and reliable manner.

At the stitcher head arrangement position S, a slider 30 that is movable along the gathering chain 16 on the fixed base 29 is arranged. The motor that drives the gathering chain 16 rotates the crankshaft 32 through a gear and a shaft. The slider 30 is connected to a crank 36 via a connecting rod 34, and travels in parallel with the gathering chain 16 during forward movement.
The slider 30 has two stitcher heads 38 mounted thereon. Although the number of stitcher heads 38 may be one or three or more, in the case of a saddle-stitched book, the signature 14 is bound at two places in many cases. The position of the stitcher head 38 can be adjusted with respect to the slider 30 in the traveling direction of the gathering chain 16. Further, a control device to which the cut-off dimension and the wire driving size are input, and an actuator for moving the stitcher head in the traveling direction of the gathering chain based on the output of the control device are provided.

When the paper edge size of the signature, the paper edge size of the finished printed matter, and the stitcher ratio are input to the control device, the wire driving position is calculated with reference to the pusher. The actuator is actuated by the output of the control device to move the stitcher head and cam back and forth to a predetermined position.
The fixed base 29 is provided with a linear cam (not shown), and the follower (not shown) is attached to the stitcher head 38. When the slider 30 reciprocates, the stitcher head 38 moves up and down. The stitcher head 38 drives one wire 18 into the signature 14 on the transport rail 12 while the slider 30 reciprocates once. The position of the linear cam can be adjusted in the traveling direction of the gathering chain 16. By adjusting the position of the cam together with the position of the stitcher head 38, the wire 18 can be driven into a predetermined position with respect to the signature 14. The position of this cam is also adjusted by an actuator.

Since the slider 30 reciprocates by the crank piston mechanism, it does not necessarily match the traveling speed of the gathering chain 16. Accordingly, the stitcher head 38 is adjusted to be actuated by the cam when the slider 30 moves forward at the maximum speed and at the chain conveying speed.
Since the gathering chain 16 and the slider 30 are operated by one motor, it is necessary to adjust the phase between the pusher 26 and the stitcher head 38. That is, since the cut-off dimensions and the like vary depending on the signature and the finished printed matter, it is necessary to finely adjust the pusher 26 that is upstream by a predetermined distance from the position where the wire 18 is driven into the signature 14. After the angular phase between the drive sprocket 20 and the drive shaft 24 is determined, the stitcher head 38 is positioned with reference to the pusher 26.

In the illustrated preferred embodiment, the gluing nozzle unit N and the signature holding member H are supplied and installed as attachments that can also be installed on the existing saddle stitch bookbinding apparatus 10. Accordingly, it is possible to selectively book a saddle stitch book using a wire or a staple, or to book a saddle stitch book using glue. When a gluing nozzle unit is added to an existing bookbinding apparatus, it is possible to detect various functions of the existing saddle stitch bookbinding apparatus, for example, dropping of a signature by a sensor. Accordingly, it is possible to bind a saddle stitch book by gluing with the addition of a minimum function.
Of course, it is also possible to remove the stitcher head and provide a glue nozzle unit N instead. In this case, the saddle-stitched book cannot be bound by wire or staples, and only the saddle-stitched book by glueing is bound.

Next, a saddle stitch bookbinding method according to the fifth invention of the present application will be described.
As shown in FIG. 5, the next signature 14 is sequentially stacked at a plurality of signature stacking positions Fn while the rear side of the hook signature 14 is pushed by the pusher 26 of the gathering chain 16. Is conveyed to the stitcher head arrangement position S and further to the bookbinding discharge position T1. In the meantime, the stitcher head 38 is arranged at a predetermined distance forward from the pusher 26 in the traveling direction, the wire 18 is driven into the back portion of the finished laminated signature, and the signature is cut in three directions leaving the back portion. The bookbinding method of the saddle stitch book according to the present invention is the same as the bookbinding method of the conventional saddle stitch book, in place of or in addition to the stitcher head 38, in front of the signature stacking position Fn. The glue is applied in a straight line while pressing both sides of the top line of the signature against the conveying rail 12 from above, and is adhered to the hook signature that has been conveyed at the time of stacking the next signature at the signature stacking position. It is made to be made to be done.

Furthermore, when holding the next signature 14 at the signature stacking position, the signature holding member H shown in FIG. 4 can also be used. Thereby, the signature 14 to be stacked can be bonded onto the hook signature while maintaining a reliable and precise positional relationship.
The bookbinding discharge position T1 and the cutting portion T2 are basically the same as those of a conventional saddle stitch bookbinding apparatus. That is, the completed laminated signature in which the wire is driven is sent to the bookbinding discharge position T1 by the gathering chain 16, where it is changed in direction, and then sent to the cutting part T2 and three-way cut.
