However, the conventional bookbinding apparatus disclosed in Patent Document 1 has the following problems. If the type of book to be bound changes, such as on-demand publishing (POD), and the size and paper quality of the text to be processed differ, it is necessary to adjust each unit accordingly. Therefore, when a large amount of bookbinding of the same type is performed, the influence on workability is small. However, when a small amount of bookbinding of different types is performed, each unit is frequently adjusted, and workability is deteriorated.

Further, in the conventional bookbinding apparatus disclosed in Patent Document 2, the amount of movement in the width direction of the width direction moving member of the bookbinding apparatus is adjusted based on the text and cover print information, but this is included in this print information. The dimension information is a specified value. However, since the actual thickness of the text varies depending on the season, weather, and the like, it may be different from the specified value included in the printed print information.

Therefore, even if the amount of movement in the width direction of the width direction moving member of the bookbinding apparatus is adjusted based on the print information, the adjustment does not match the actual text to be processed, and the quality of bookbinding is impaired. There is.

The present invention has been made in view of such problems, and an object of the present invention is to provide a bookbinding apparatus that can perform bookbinding processing based on the actual thickness of the text and can improve the quality of bookbinding.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of a bookbinding apparatus using an XY actuator according to the present invention. In the figure, the bookbinding apparatus 10 is roughly arranged in the movable range of the XY actuator 12, the hand unit 14 provided in the moving part 12a of the XY actuator 12, and the moving part 12a of the XY actuator 12. The table unit 15, a plurality of bookbinding units 16 arranged on the table unit 15, a control unit 18 (FIG. 5) for controlling the XY actuator 12 and each bookbinding unit 16, and the control unit 18. An output unit 20 (FIG. 5), a cover information reading unit 22 (FIG. 5) that reads bookbinding information printed on the cover, and a text information reading unit 24 that reads bookbinding information printed on the text.

As the XY actuator 12, for example, a linear induction motor type XY actuator can be used. In the drawing, an X axis stage 12x along the X direction, a Y axis stage 12y along the Y direction, and a Z direction. Z axis stage 12z is provided, and moving part 12a can be positioned with high accuracy. Here, the X axis and the Y axis are two orthogonal axes in the horizontal plane, and the Z axis is an axis along the vertical direction.

The Y-axis stage 12y is slidably mounted along the X direction with respect to the pair of X-axis stages 12x, the Z-axis stage 12z is slidably mounted along the Y direction, and the moving unit 12a is attached to the Z-axis stage 12z. On the other hand, it is slidably attached along the Z direction.

As described above, in the example shown in FIG. 1, the moving unit 12a has a degree of freedom in the three axis directions of the XYZ axes by the operation of the XY actuator 12, and can move to any three-dimensional position. Yes.

Instead of the example shown in FIG. 1, as shown in FIG. 2, at least, only the X-axis stage 12x and the Y-axis stage 12y may be provided. In this case, the moving unit 12a has a degree of freedom in the two axis directions of the XY axes by the operation of the XY actuator 12, and can move to any two-dimensional position.

Alternatively, instead of the example shown in FIG. 1, as shown in FIG. 3, a rotation shaft 12θ that can rotate around the Z axis with respect to the Z axis stage 12 z can also be provided. As a result, the moving unit 12a has a total of four degrees of freedom around the three axes of the XYZθ axes and a total of one axis by the operation of the XY actuator 12, and can move to any four-dimensional position. Yes.

The hand unit 14 provided in the moving part 12a includes two

clamp plates

14a and 14b for fastening the text. The distance between the two

clamp plates

14a and 14b can be adjusted by a servo motor 14c which is an electric motor which is a clamp actuator.

When the servo motor 14c rotates from the state in which the two

clamp plates

14a and 14b are at the initial interval and sandwich the text P, the interval between the two

clamp plates

14a and 14b is reduced and the text is tightened. When the torque by the motor 14c reaches a predetermined value, the servo motor 14c is stopped assuming that a sufficient tightening force is obtained. The servo motor 14c detects the rotation angle of the servo motor 14c, converts the rotation angle signal into the movement distance of the

clamp plates

14a, 14b from when the servo motor 14c starts to rotate until it stops, Is further provided as an encoder serving as a thickness detection means 30 for outputting the signal as a thickness signal for converting the thickness into a thickness (initial interval−movement distance) of the text.

The table unit 15 disposed in the movable range of the hand unit 14 provided in the moving unit 12a of the XY actuator 12 is appropriately provided with a partition, and a bookbinding unit 16 is disposed at each partition. Further, predetermined positions of the table unit 15 are an inlet IN and an outlet OUT.

The bookbinding unit 16 may be an arbitrary unit that executes each process for bookbinding. Preferably, the two-dimensional dimensions of several bookbinding units 16 are the same. As the bookbinding unit 16 set in the table unit 15, for example, in the case of normal bookbinding, a cutting cutter unit, a gully cutter unit, a sander cutter unit, a horizontal glue unit, a back glue unit, a cover sheet supply unit, a press molding clamping unit, A three-way cutting unit can be exemplified. In the case of upper bookbinding, for example, a cold chiller feeder unit, a cold chiller tuning unit, and the like can be added.

Each bookbinding unit 16 changes its configuration according to the process to be executed, but basically includes an operating element (for example, a cutter, a roller, a guide plate, a press plate, etc.) that operates on the main body, and an operating element. A drive element (for example, an electric motor, a fluid pressure cylinder, etc .: not shown) for operating is provided. The actuating element and the driving element may be common in a plurality of bookbinding units.

Each bookbinding unit 16 can be detachably disposed with respect to each partition of the table unit 15, and the bookbinding unit 16 is positioned with respect to the reference position of each partition of the table unit 15, thereby resulting in XY Positioned relative to the actuator 12.

The arrangement of these bookbinding units 16 is two-dimensionally arranged so as to be continuous in the X and Y directions, and the arrangement order is arbitrary. 4A to 4C show examples of arrangement.

The direction of the operating elements of each bookbinding unit 16 need not be aligned in the same direction in all bookbinding units 16. The direction can be changed by the movement path by the XY actuator 12 as illustrated in FIG. Alternatively, when the XY actuator 12 having four axes of freedom as shown in FIG. 3 is used, the orientation of the text itself held by the hand unit 14 can be changed. It is also possible to make the orientation constant and instead change the orientation of the text according to the bookbinding unit 16.

Further, as shown in FIG. 4, it is not always necessary to arrange them adjacent to each other in the order of the bookbinding process. For example, a bookbinding unit that an operator needs to access frequently for adjustment, maintenance, etc. is accessed. It is also possible to improve workability by arranging it at a position in front of it. In addition, a bookbinding unit that requires replenishment from the outside, for example, a cover supply unit, may be arranged at a position that is easily accessible.

Further, as shown in FIG. 4, the movement path of the moving unit 12a by the XY actuator 12 does not necessarily pass through all the bookbinding units 16. For example, one of the bookbinding units 16 depends on the bookbinding conditions. You may come to skip. Alternatively, the movement path of the bookbinding unit 16 may be different depending on the bookbinding conditions.

FIG. 8 is a diagram showing a specific configuration of the cover sheet supply unit 16X in the bookbinding unit 16. As shown in FIG. The cover supply unit 16X includes a cover standby unit 162 in which covers are stored, a cover transport unit 164 that sucks and transports one of the stored cover standby units 162, and a cover transported by the cover transport unit 164. Is provided with a tuning unit 166 and a pair of CCD sensors 168 for detecting the inclination of the cover.

The control unit 18 controls the position control of the XY actuator 12 and the movement in the bookbinding unit 16 in accordance with bookbinding information read from a cover reading unit 22 and a text information reading unit 24 described later. Further, a thickness signal corresponding to the rotation angle signal from the thickness detection means 30 is input to the control unit 18, and the thickness of the text actually held by the hand unit 14 is obtained by this thickness signal, and this The movement of the bookbinding unit 16 is controlled by the thickness.

That is, as shown in FIG. 5, the control unit 18 controls the position of the moving unit 12a by controlling the XY actuator 12 with a control signal. As illustrated in FIG. 4, the moving unit 12 a is moved along the movement path determined based on the bookbinding conditions, and the hand unit 14 is transported to the bookbinding unit 16, and is determined in each bookbinding unit 16. The hand unit 14 is fixed at the position, or the hand unit 14 is controlled to perform the movement (position, speed (speed, direction)) determined based on the bookbinding conditions and the thickness signal from the thickness detection means 30.

Further, the control unit 18 drives the drive elements so that the operation elements are positioned at positions determined based on the bookbinding conditions and the thickness signal from the thickness detection means 30 for each bookbinding unit 16. In accordance with the current position of the moving unit 12a, the driving element of each bookbinding unit 16 is driven by the control signal to control the start and end of the operation of the operating element. The bookbinding unit 16 does not need to operate in synchronization, and can start and end operation independently in accordance with a control signal from the control unit 18.

The control unit 18 is connected to an output unit 20 that performs display in a manner that can be detected by sound, vision, or any other human being.

The cover information reading unit 22 is provided in the cover supply unit 16X in the bookbinding unit 16, and reads bookbinding information printed on the cover taken out by the cover supply unit. This reading operation is preferably performed automatically. Specifically, in the cover sheet supply unit 16 </ b> X of FIG. 8, the cover information reading unit 22 is provided between the cover standby unit 162 and the tuning unit 166.

The text information reading unit 24 is provided near the entrance of the bookbinding unit 16 and reads bookbinding information printed on the text before being held by the hand unit 14. Activation of this reading operation is preferably performed manually.

The bookbinding apparatus 10 is an apparatus independent of a printing machine (not shown), and the text printed on the printing machine and the cover are separately conveyed to the bookbinding apparatus 10. In the printing machine, the text and the cover are printed, and the bookbinding information is printed together with the contents. The text P may be a signature or paper sheets collated by a collating machine, or other existing paper sheets.

Bookbinding information printed by a printing machine and read by the cover information reading unit 22 and the text information reading unit 24 includes a rod number or other identification information, a text height, a text width, and a text thickness (thickness here). Is a specified value), dimensions such as mass, paper quality, glue thickness, bookbinding unit via, movement of the XY actuator in each bookbinding unit, and other bookbinding condition information. When a one-dimensional code such as a bar code is used, the amount of information is limited, so only the identification information may be used. When a two-dimensional code is used, more information can be included. Not only bookbinding condition information including dimensions should be included. If the amount of bookbinding information to be printed is limited, the remaining necessary information may be supplied to the control unit 18 via another recording medium or the like. It is preferable that the information can be extracted.

The bookbinding information may be printed on the text and cover parts that are later cut off by three-way cutting, or on the parts that are inconspicuous after bookbinding.

In the bookbinding apparatus 10 using the XY actuator configured as described above, a text P to be used for bookbinding processing is waiting at the entrance IN. Further, a cover is waiting in the cover standby unit 162 of the cover supply unit 16X.

In the cover supply unit 16X, the cover transport unit 164 operates in response to a command from the control unit 18, and the cover transport unit 164 sucks the top cover of the cover that has been waiting in the cover standby unit 162, and synchronizes the unit 166. It pulls out towards (the virtual line of FIG.8 (b)). Then, the cover reading unit 22 operates in accordance with a command from the control unit 18 and the bookbinding information of the taken cover is read.

On the other hand, for the text P waiting at the entrance IN, the text information reading unit 24 reads the bookbinding information. The activation of the text information reading unit 24 is preferably manually performed by an operator.

The bookbinding information read by the cover reading unit 22 and the text information reading unit 24 is collated by the control unit 18.

As an example of collation, it can be seen whether or not the identification information matches. Alternatively, it can be determined whether or not the identification information has a corresponding relationship. That is, a combination table of a text and a cover to be combined with the text may be stored in the control unit 18 in advance, and it may be determined whether the combination is correct with reference to the combination table. .

The control unit 18 outputs the determination result signal to the output unit 20 based on the determination result, and the output unit 20 performs display by sound, vision, and the like.

When the determination result that the combination is not correct is output from the output unit 20, the worker replaces the text with another one, and the text information reading unit 24 again binds the text that seems to be correct. Information can be read, and the operation can be repeated until a determination result indicating that the information is correct is output from the output unit 20.

In this way, by allowing the operator's judgment to intervene, flexible response becomes possible, the correct combination can be reached quickly, and bookbinding processing can be performed efficiently. By checking whether the combination is correct before being held by the hand unit 14 and before being processed by the bookbinding unit 16, it is possible to prevent the quality of the text from being impaired.

When the correct combination text is input to the IN position, the control unit 18 moves the moving unit 12a to the IN position by the XY actuator 12 to control the clamping actuator 14c, thereby The body P waiting by the unit 14 is gripped and tightened to have a predetermined tightening force. Here, the predetermined tightening force may be changed according to the bookbinding condition information obtained from the bookbinding information read as described above. Then, as described above, the thickness of the actual text P held by the hand unit 14 and being tightened is detected by the thickness detection means 30, and the XY actuator 12 follows the predetermined movement path. Then, the bookbinding unit 16 conveys the text P.

Here, an example of a control flow for obtaining the thickness of the text will be described with reference to FIG.
First, the value of the torque of the servo motor 14c is detected (step 100), and it is determined whether or not the torque value has become a predetermined torque value determined in advance (step 102). If the torque value is not the specified torque value in step 102, the process returns to step 100. If the specified torque value is reached, the servo motor 14c is stopped and the rotation angle from the start to the stop of the servo motor 14c is detected. (Step 104). From this rotation angle, the moving distance from the initial interval between the two

clamp plates

14a, 14b of the hand unit 14 is calculated, and the thickness of the text P corresponding to the current interval between the

clamp plates

14a, 14a is calculated (step 106). . Thereby, the actual thickness of the text held by the hand unit 14 is detected.

Preferably, when the bookbinding information on the cover is read and the thickness of the text is detected, the control unit 18 binds the book based on the bookbinding condition information obtained from the read bookbinding information and the detected actual text thickness. The drive element is driven according to the unit 16 to activate the actuating element.

That is, the bookbinding unit 16 positions the operating element in the width direction based on the text thickness detected by the thickness detector 30 and the information on the text height, width, paper quality, etc. included in the bookbinding condition information, or Position the actuating element in the height direction.

Then, based on the control of the control unit 18, the XY actuator 12 controls the XY coordinates, XYZ coordinates, or XYZθ coordinates of the moving unit 12a, thereby positioning the text P with respect to the operating element.

When the predetermined bookbinding process is executed sequentially through the bookbinding units 16 thus determined and the exit OUT is reached, the control unit 18 releases the holding of the text P by the hand unit 14 and the next text. For the processing of P, the moving part 12a is moved again to the inlet IN.

Further, while one bookbinding operation is being performed, in the cover sheet supply unit 16X, the next cover sheet is pulled out, and the bookbinding information is read by the cover sheet reading unit 22, so that the control unit 18 uses the bookbinding information. Based on the obtained bookbinding condition information, the bookbinding unit 16 that has finished the work may be driven according to the bookbinding conditions for the next book to drive the driving element of the bookbinding unit 16 to activate the operating element. Thus, the work can be performed efficiently. If the bookbinding condition information is included in the bookbinding information printed on the cover, the control unit 18 can directly drive each driving element from the read bookbinding condition information, and the processing can be made more efficient. it can.

6 and 7 are specific examples of the bookbinding apparatus using the XY actuator according to the present invention. In this example, the cutting cutter unit 16A, the gutter cutter unit 16B, the sander cutter unit 16C, the lateral glue unit 16D, the back glue unit 16E, the cover sheet supply unit 16X, and the press molding fastening unit 16H are arranged at appropriate positions on the table portion 15, respectively. Has been.

The cutting cutter unit 16A includes a milling cutter 170 for cutting the back surface of the text P and a pair of guide plates 172 that press the text from both sides as operating elements. The text P is conveyed by the XY actuator 12. Then, the pair of guide plates 172 press the body P from both sides by the driving elements, and the driving elements move the milling cutter 170 along the back surface while rotating.

The width of the pair of guide plates 172 of the cutting cutter unit 16 </ b> A is adjusted according to the thickness of the text P detected by the thickness detection means 30. Further, the stroke of the milling cutter 170 is adjusted according to the height of the text P in the bookbinding conditions.

The gully cutter unit 16B and the sander cutter unit 16C are a pair of gully cutters 180 that form gully grooves on the back side of the text P, a sander cutter 182 that polishes the back side of the text P, and a pair of pressing and guiding the text P from both sides. A guide plate 184 is provided as an actuating element. When the text P is conveyed by the XY actuator 12, the pair of guide plates 184 hold the text P from both sides by the driving element, and the driving element rotates the gully cutter 180. The drive element rotates the sander cutter 182.

The stroke of the gutter cutter 180 is adjusted according to the thickness of the text P detected by the thickness detection means 30, and the width of the pair of guide plates 184 is adjusted according to the thickness of the text P.

Also, the rotation direction of the sander cutter 182 varies depending on the binding conditions. Therefore, the rotation direction of the sander cutter 182 is changed according to the bookbinding conditions.

The text P is fixedly held, and the gutter cutter 180 and the sander cutter 182 move while rotating, and each of the back surfaces of the text P is grooved and polished. Unlike proceeding with, the finished surface can be finished beautifully. In particular, burrs have conventionally been generated by a gutter cutter, but in the present invention, such burrs can be reduced. Further, since burr is conventionally generated by a gutter cutter, it has been indispensable to subsequently perform polishing with a sander cutter, whereas in the present invention, generation of burr due to a gutter cutter can be reduced. Therefore, the order of processing by the gully cutter unit 16B and the thunder cutter unit 16C can be switched. In other words, by forming the gully groove after polishing, it is possible to prevent the powder due to polishing from entering the gully groove, and in order for the glue to enter the gully groove in the next glue application work, The paste can be improved.

The horizontal gluing unit 16D includes a pair of rollers 190 that apply glue to the lateral side of the text as an operating element. When the text P is conveyed by the XY actuator 12, the driving element rotates the pair of rollers 190. It is supposed to let you.

The distance between the pair of rollers 190 of the horizontal gluing unit 16D is adjusted according to the thickness of the text P detected by the thickness detecting means 30.

The back gluing unit 16E includes a roller 192 for applying glue on the back of the text, a glue scraper 194, and a correction roller 196 as operating elements. When the text P is conveyed by the XY actuator 12, the driving element is a roller. 192 is rotated, the drive element swings the glue scraper 194, and the drive element adjusts the vertical height of the correction roller 196.

The operating time and the swing angle of the glue scraper 194 are adjusted according to the height of the book to which glue is attached under the bookbinding conditions and the thickness of the glue. The vertical height of the correction roller 196 is adjusted according to the thickness of the glue in the bookbinding conditions.

In the cover sheet supply unit 16X, the cover sheet whose bookbinding information has been read is placed on the tuning section 166 by the cover sheet transport section 164. Further, in the tuning unit 166, a pair of CCD sensors 168 image two portions of the cover R, and this imaging information is sent to the control unit 18 to detect the inclination of the cover printing. . In the tuning unit 166, the orientation of the cover is adjusted according to the detected inclination, or the orientation of the XY actuator 12 is adjusted according to the detected inclination, and the XY actuator 12 The conveyed text P and cover R are combined.

The press molding fastening unit 16H includes a pair of press plates 200 as an operating element. When the body P and the cover sheet R bonded to the body P are conveyed by the XY actuator 12, the drive element is paired with the pair of press plates 200. The press plates 200 are moved in a direction approaching each other, and the text and the cover are combined and pressed from the side.

The width of the pair of press plates 200 of the press molding fastening unit 16H is adjusted according to the thickness of the text P detected by the thickness detecting means 30.

Thus, since the positioning adjustment of the operation element of each bookbinding unit 16 is performed according to the bookbinding information and the thickness of the text P detected by the thickness detection means 30, the position suitable for the book type and the actual state of the text The actuating element can be actuated. Even if the thickness of the text is slightly different from the specified value due to the season, weather, and other conditions, the quality of the bookbinding can be improved. Further, the bookbinding information and the thickness information of the text P detected by the thickness detecting means 30 are also transferred to an arbitrary machine (for example, a three-way cutting machine) provided downstream of the bookbinding apparatus 10 and performing a post-process, It may be used for adjustment in processing in the machine.

Based on the bookbinding information and the detected thickness information, the conveyance by the XY actuator 12 and the operation of each bookbinding unit 16 are controlled by the control unit 18, so that various kinds of small quantities such as on-demand publishing (POD) can be obtained. It can flexibly handle bookbinding.

In the above-described embodiment, an encoder that detects the rotation angle of the servo motor 14c is used for detecting the thickness of the text P by the thickness detector 30, but the present invention is not limited to this. When the distance between the two

clamp plates
