Description

  The present invention relates to a bookbinding apparatus. Further, the present invention relates to a bookbinding book manufactured using the bookbinding apparatus.

  At present, there are books in various formats, but there are upper bookbinding and ordinary bookbinding according to bookbinding formats.

  The upper bookbinding is a bookbinding format also called a hard cover (hard cover), and the cover is formed by wrapping a core paper such as cardboard with a cover paper, and the cover is manufactured with a size that is one size larger than the text. The main text and facing paper are bonded together and bound. The part of the difference between the cover and the text is called “Chile”. On the back of the upper bookbinding, a braid string (also called a ribbon, a spin, etc.) is selectively provided. According to a known technique, it is possible to bond the string to the back of the text on the same bookbinding line. For this reason, an external device (outline) is not required for the lacing when manufacturing the upper bound book.

On the other hand, average bookbinding is a bookbinding format called a soft cover, and no cover paper is used for the cover, and it is finished with the same dimensions as the main text. In the bookbinding process, the body and cover are finished at the same time. Average bookbinding is preferred for magazines and inexpensive paperback books because of its short manufacturing process and low cost. In the case of ordinary bookbinding, it is generally performed on a bookbinding line called a binder, but there is no equipment that can provide a string on the same line on the same line.
However, as for the paperback, some devices are known for sticking candy on the cover. The apparatus includes a transport unit, a rotating body that is divided into three parts every one third of the outer periphery, a suction unit disposed on the rotating body, a cutting unit that cuts a ridge, and a pasting unit. It is possible to affix a string with a length of one third of the circumference continuously to the cover. However, this device only supports the library size and is not versatile.

For this reason, in ordinary bookbinding, when a string is required, it is often affixed to the back of the text by hand-pasting or using the equipment of the upper production line. However, when utilizing the equipment of the upper production line, the line is temporarily stopped and the upper production line is used. Therefore, it may occur that the upper production line used for other bookbinding is stopped. For this reason, production efficiency is extremely poor, and there is a problem in cost.
To deal with this problem, there are documents (for example, refer to Patent Document 1) that disclose a method for providing a bag on the back of the text of the standard bookbinding, but lack of practicality due to problems of manufacturing cost and labor.

On the other hand, in the publishing industry, electronic books and the like have been recognized, and it is feared that the demand for bound books will decrease in the future. Furthermore, with regard to bookbinding books in which multiple copies of the same item are issued for mass sales, further cost reduction is required, and the bookbinding environment is becoming increasingly severe.

  Therefore, it is desired to provide a new bookbinding apparatus that can efficiently provide a string for a regular bookbinding.

Japanese Patent No. 3608337

  Therefore, an object of the present invention is to provide a bookbinding apparatus capable of efficiently providing a string for all sizes of normal bookbinding. Furthermore, it is an object of the present invention to provide a new type of mechanical book that has not been manufactured because of its cost reduction.

In order to achieve the above object, the bookbinding apparatus of the present invention comprises:
A transport device that transports the cover, a rotating body that rotates while holding the hook string in the outer periphery, and a cutting device that cuts the hook string,
The rotating body has a gear shape having a plurality of recesses along the outer periphery at a position where the string can be continuously cut with a length of the string suitable for a plurality of formats, and is driven by a stepping motor or a servo motor. Is controlled,
The cutting device includes a cutting portion and a slide portion for cutting the lacing string at the concave position,
The slide portion preferably includes a plurality of slide grooves capable of sliding the cutting portion in an arc shape along the rotating body, and a plurality of fixing means capable of fixing the cutting portion at a predetermined position.

In addition, it is preferable to include a control device including means for controlling the rotation speed and rotation angle of the rotating body and means for instructing cutting in synchronism with gluing of the leash to the cover.
Further, it is preferable that the fixing means also serves as the format input means.
In addition, it is preferable that the cutting part includes a manual handle for sliding the cutting part.

Further, the present invention uses the bookbinding apparatus described above, and synchronizes the step of fixing the position of the cutting portion with the fixing means, the step of rotating the rotating body at a predetermined speed, and the glue and cutting of the leash string to the cover. The bookbinding cover includes a bookbinding cover manufactured by the manufacturing method and a machine-bound book using the bookbinding cover.

That is, according to the present invention, it is possible to attach a string to the cover of every normal bookbinding with a single device, instead of attaching a string to the back of the book body. If the bookbinding apparatus of the present invention is used, it is possible to produce approximately 5,000 covers per hour, and the production efficiency increases dramatically.
Furthermore, by using the cover manufactured by the bookbinding device on the conventional average bookbinding line, it becomes possible to machine the average bookbinding on a single line, dramatically improving the production efficiency, and tens of thousands of It becomes possible to provide easy and efficient bookbinding by mechanical bookbinding with a lacing string of more than one unit.
Furthermore, since it becomes possible to provide a machine-bound book of ordinary bookbinding with a string on the cover other than the paperback, the degree of freedom in bookbinding design is also improved.

  If it demonstrates more concretely, the bookbinding apparatus of this invention is provided with the conveying apparatus which conveys a cover. This is the same as in the prior art, and the cover can be conveyed toward the rotating body at a predetermined speed. A gluing device is incorporated in the lower part of the contact point with the rotating body, and the gauze string and the cover can be glued by pushing up the gluing device from the lower part. For example, it is also possible to adopt a form in which the cover and the string with the glue sprayed in the previous stage are pressed by the glue device.

  The rotating body has a gear shape having a recess at a position where the length of the string suitable for a plurality of formats can be continuously cut along the outer periphery, and rotates while holding the string in the outer periphery. Is possible. The holding in the outer periphery is preferably realized by means for adsorbing the bracelet to the convex portion using a pressure difference from the inside of the rotating body. For example, the inside of the rotating body is connected to a vacuum pump, and the string is adsorbed to the rotating body using a pressure difference through a hole provided in the convex portion. If necessary, a pressing mechanism using a spring or the like may be provided from the outside.

The concave portion is provided so as to set the length of the string required for the desired format and continuously cut it to the set constant length. This configuration, in combination with other configurations of the present invention, can select a desired length, such as A6 size or A5 size, for example, and can be continuously cut and pasted on the cover sheet.

The length of the saddle string is the length from the attachment position of the cover and the saddle string, that is, from the contact point between the rotating body and the conveying unit to the cutting position by the cutting unit. A recess is provided at a position where the length can be continuously cut. For example, when a desired length is given at a 90-degree position (for example, equivalent to A6) and 120 degrees (for example, equivalent to A5), it is provided every 30 degrees.

From another point of view, it is preferable to provide a common divisor of a plurality of required angles, preferably for each angle of the greatest common divisor. The width and depth of the recess may be designed as appropriate as long as the cutting portion has sufficient depth and width to cut the ridge. For example, A4, A5, A6, B5, B6, and a new letter format are all provided with a recess at a selectable position. There are preferably 60 or more recesses (or every 6 degrees).

Regarding the format, general format size (mm) and main uses are as follows, although they are already known.
B4 size 257 x 364 art book, graph magazine, etc.
A4 size 210 × 297 Photobook etc.
B5 size 182 × 257 Weekly magazines, magazines, etc.
A5 size 148 × 210 General magazines, textbooks, etc.
B6 size 128 × 182 book etc.
A6 size 105 × 148 paperback books, etc. New book size 103 × 182 new book books, comic books, etc. However, the present invention can be applied not only to the above-mentioned format, but also to any format such as AB size 210 × 257, 35 size 84 × 148, and chrysanthemum size 150 × 220. Furthermore, the length of the desired lacing cord is almost empirically determined according to the format, but according to the present invention, by changing or adjusting the positions of the recesses and the fixing means, the combination can be determined. Not only that, it is also possible to attach a longer (or shorter) string than usual, so that the degree of freedom in designing the bookbinding can be improved.

In the present invention, the motor that drives the rotating body is a stepping motor that rotates at a constant angle by sequentially switching the current that flows through the motor coil in accordance with a pulse signal transmitted from the controller, or an encoder attached to the motor. A servo motor that rotates while feeding back the current position and speed and correcting an error from the operation command pulse is used. With this configuration, accurate positioning can be controlled at a high speed in accordance with the required rotation angle, so that the object of the present invention can be achieved.

  The cutting device includes a cutting part and a slide part. The cutting part can cut the string in the concave part of the rotating body. For this reason, it is preferably constituted by a sandwiched cutting blade. The cutting control can be performed by various known means, but it is preferable to use an electromagnetic coil type switch (solenoid) in order to perform the cutting control at a high speed.

The slide part includes a plurality of slide grooves capable of sliding the cutting part in an arc shape along the rotating body and fixing means capable of fixing the cutting part at a predetermined position.
The cutting part preferably includes a handle that can be manually slid with a sliding mechanism on the slide groove. With this configuration, it is possible to easily change the cutting position manually. The slide portion is provided with a fixing means that can also fix the cutting portion at a predetermined position and also serves as a format designation means. Specifically, the cutting portion is fixed to a position where cutting can be performed at an angle corresponding to various sizes from the position where the string is attached, for example, by a pin / pinhole or a fitting mechanism. A plurality of fixing means are provided on the slide portion according to various sizes, and can be continuously cut to a required length.

As a control device of the bookbinding device of the present invention, a control device having a known configuration such as a CPU, a ROM, and a RAM is used, and means for controlling the rotation speed and rotation angle of the rotating body according to the format, and the cover is cut Means for instructing in synchronization with the gluing of the braid string. In particular, it is preferable that the fixing means also serves as an input means (type designation means) to the control device. By fixing the cutting portion, control according to the type set in advance is performed. By making the selection automatically, it is possible to manufacture more efficiently. For example, a pin is used as a fixing means, a pin hole is provided in the slide part, a sensor or a switch is provided at the bottom of the pin hole, and the fixing of the cutting part and the format designation of the control device are performed simultaneously by inserting the pin. Can be adopted. However, the implementation format is not limited to the above format, and various implementation formats such as a format for inputting a format separately in the control device and a format for automatically moving the cutting device to a predetermined place when the format is input. Can be adopted.

A specific procedure for using the bookbinding apparatus of the present invention will be described. The controller records in advance the rotational speed and rotational angle of the rotating body required for the format according to the speed and timing at which the cover is conveyed.
First, the position of the cutting part is fixed according to the required format. When the cutting part is fixed, the format is automatically selected and input to the control device.
Then, while carrying the cover, the rotating body is rotated at a predetermined speed, and the gluing and cutting of the string on the cover are performed in synchronization, and this process is repeated continuously.
