The spine attachment device disclosed in Patent Document 1 is configured to glue a spine to an intermediate fold among the multiple folds that make up a booklet, and then stack the folds. The spine attachment device disclosed in Non-Patent Document 1 is configured to attach a spine to the top side of the spine of the booklet by gluing. When using the spine attachment device disclosed in Non-Patent Document 1, the booklet may be transported with the base part of the booklet at the front. When transporting such a booklet, the spine attached to the top side of the spine of the booklet becomes frayed or peels off due to friction, which poses the problem of requiring repairs to the attachment of the spine, resulting in high costs.

The present invention aims to provide a spinner attachment device that prevents the spinner from becoming frayed or peeling off by attaching the spinner to the cover of the booklet, such as the front cover of the booklet, and eliminates the need to repair the attachment of the spinner to the booklet.

That is, the present invention is a spindle attachment device that includes a sheet body supply unit that supplies a sheet body that will become a booklet cover, a transport unit that transports the sheet body supplied from the sheet body supply unit, an adhesive application unit that applies adhesive to a predetermined location on the sheet body transported by the transport unit, a spindle attachment unit that attaches the spindle to the adhesive using a spindle gripper that moves back and forth between a standby position where the spindle pulled out from the bobbin is waiting and an attachment position to the adhesive applied to the sheet body by the adhesive application unit, and a sheet body storage unit that stores the sheet body to which the spindle is attached.

This prevents the spine from becoming frayed or peeling off by attaching it to the cover of the booklet, and eliminates the need to repair the attachment of the spine to the booklet.

The conveying section further includes a conveyor belt that circulates along the conveying direction while contacting the bottom surface of the sheet body, a guide wall that rises from the conveying surface of the sheet body at a position outside the widthwise end of the conveyor belt and positions the widthwise position of the sheet body in the conveying direction, a sheet body pressing body that is arranged in a state spaced apart from the upper surface of the sheet body and contains a plurality of pressing balls that can rotate on the upper surface of the sheet body conveyed by the conveyor belt, and a stopper body that is arranged to be able to move back and forth between an abutment position where it contacts the sheet body conveyed by the conveyor belt and a non-abutment position where it does not contact the sheet body conveyed by the conveyor belt and that temporarily stops the sheet body at the predetermined position, and it is preferable that the planar position of the conveyor belt approaches the guide wall as it proceeds from the upstream side of the conveying direction to the downstream side of the conveying direction.

This allows the sheet to be transported in an accurately positioned state, and the spine can be attached to the appropriate location on the sheet.

It is also preferable that an additional pressing section is disposed between the spin adhesive section and the sheet body storage section, which presses the tip gripping section of the spin that was gripped by the spin gripping body against the adhesive. It is also preferable that the spin gripping body presses a part of the spin against the adhesive while gripping the tip gripping section of the spin, and then releases the grip of the tip gripping section of the spin and presses the tip gripping section of the spin against the adhesive.

This ensures that the spine adheres securely to the sheet body.

The configuration of the spine attachment device of the present invention prevents the spine from becoming frayed or peeling off by attaching the spine to the cover of the booklet, and eliminates the need to repair the attachment of the spine to the booklet.

As shown in Figs. 1 and 3, the spin attachment device 100 in this embodiment includes a sheet body supply unit 10, a conveying unit 20, an adhesive application unit 30, a spin adhesion unit 40, an additional pressing unit 50, a sheet body storage unit 60, and an operation control unit 70. The sheet body ST supplied from the sheet body supply unit 10 to the conveying unit 20 is repeatedly paused at a predetermined position in the conveying direction, and after the spin SP is attached by the spin adhesion unit 40, it is conveyed to the sheet body storage unit 60. Note that the sheet body ST that becomes the cover of the booklet in this embodiment is exemplified as a cover attached to the booklet, but the sheet body ST that becomes the cover of the booklet in this invention is not limited to a cover attached to the booklet, and is a concept that includes a book cover that can be attached and detached to the outer surface of a booklet such as a book or a memo pad.

As shown in Figs. 1 and 2, the sheet supply unit 10 in this embodiment includes a first stocker 11, a second stocker 12, a first conveyor belt 13, a second conveyor belt 14, and an air adsorbent 15. The first stocker 11 is a portion where the sheet ST that will become the cover of the booklet is inserted by the operator. The sheet ST inserted into the first stocker 11 is sequentially supplied to the second stocker 12 by the first conveyor belt 13 and the second conveyor belt 14. The sheet ST supplied to the second stocker 12 is sequentially inserted into the conveying unit 20 by the air adsorbent 15. The supply operation of the sheet ST by the sheet supply unit 10 is controlled by the operation control unit 70 based on a sheet detection signal from a sheet detection sensor (not shown) arranged on the conveying path.

As shown in Figs. 2 and 3, the conveying section 20 in this embodiment includes a conveyor belt 21, a guide wall 22, a sheet body pressing body 23, and a stopper body 24. The conveyor belt 21 circulates in the conveying direction of the sheet body ST while abutting against the bottom surface of the sheet body ST between a position immediately downstream of the sheet body supplying section 10 and a position immediately upstream of the sheet body storage section 60. The conveyor belt 21 circulates at all times and conveys the sheet body ST in the conveying direction. Stopper bodies 24 are arranged at predetermined positions in the conveying section 20, namely, the adhesive application section 30, the spin adhesion section 40, and the additional pressing section 50, and the sheet body ST conveyed to the conveying section 20 is conveyed intermittently in the conveying direction while temporarily stopping at the position of the stopper body 24. The conveying operation of the sheet body ST by the conveyor belt 21 is controlled by the operation control section 70 based on a sheet body detection signal from a sheet body detection sensor (not shown) arranged on the conveying path.

The guide wall 22 is a standing wall that rises from the conveying surface at a position outside the widthwise end of the conveyor belt 21. The guide wall 22 is arranged in a planar arrangement parallel to the center line of the sheet body ST in the conveying direction while being held by the slider 26. The horizontal distance of the guide wall 22 from the conveyor belt 21 can be adjusted by the slider 26. This allows the position of the sheet body ST to be adjusted by a simple operation even if the size of the sheet body ST is changed. In addition, the conveyor belt 21 in this embodiment is arranged in a planar arrangement in which the position of the center line CL in the widthwise direction of the conveyor belt 21 gradually approaches the guide wall 22 as the sheet body ST progresses from the upstream side to the downstream side in the conveying direction. By arranging the conveyor belt 21 in this way in a planar arrangement, one edge of the sheet body ST, which is the object of conveying, parallel to the conveying direction, is always pressed against the guide wall 22 during conveying. This allows the sheet body ST to be positioned in the widthwise direction in the conveying direction by abutting it against the wall surface of the guide wall 22 during conveying.

A sheet body pressing body 23 is disposed at a position above the conveyor belt 21 (above the conveying surface) with a required distance between it and the upper surface of the conveyor belt 21 and in the same plane as the conveyor belt 21. The sheet body pressing body 23 has a plate-shaped body 23B with a plurality of through holes 23A bored at equal intervals, and a pressing ball 23C accommodated in each through hole 23A. The diameter of the pressing ball 23C is smaller than the diameter of the through holes 23A bored in the plate-shaped body 23B, and a part of the outer surface of the pressing ball 23C protruding from the lower surface of the plate-shaped body 23B presses the sheet body ST against the upper surface of the conveyor belt 21 by the weight of the pressing ball 23C. As a result, even if the sheet body ST is lightweight, the bottom surface of the sheet body ST can be reliably brought into contact with the conveyor belt 21 at the position of the pressing ball 23C, and the sheet body ST can be transported without clogging.

On the conveying surface at the widthwise outer position of the conveyor belt 21, two stopper bodies 24 are arranged at each of the positions of the adhesive application section 30, the spin adhesive section 40, and the additional pressing section 50, which are predetermined positions in the conveying direction. The stopper bodies 24 are accommodated in the planar area of the long hole 25 formed on the conveying surface at the widthwise outer position of the conveyor belt 21. The stopper bodies 24 can move between a position where they protrude from the upper surface of the conveyor belt 21, which is a position where they abut against the sheet body ST, by a fluid cylinder (not shown), and a position where they are retracted from the upper surface of the conveyor belt 21, which is a position where they do not abut against the sheet body ST. In this embodiment, the stopper bodies 24 can change their position of advancement and retreat from the conveying surface at any position within the long hole 25 depending on the size of the sheet body ST to be conveyed. The advancement and retreat of the stopper bodies 24 at predetermined positions in the conveying direction of the sheet body ST is controlled by the operation control unit 70 based on a sheet body detection signal from a sheet body detection sensor (not shown) arranged on the conveying path.

As shown in Figs. 1 and 2, the adhesive application unit 30 in this embodiment is disposed between the sheet body supply unit 10 and the spin adhesive unit 40 described later. The adhesive application unit 30 has a container 31 containing adhesive GL, a nozzle 32 that applies the adhesive GL in the container 31 to the sheet body ST, and a moving mechanism 33 that moves the container 31 and the nozzle 32. In this embodiment, the nozzle 32 is attached integrally to the container 31. The moving mechanism 33 can reciprocate in the height direction (arrow A in Fig. 2) relative to the conveying surface of the sheet body ST and in the width direction (arrow B in Fig. 2) in the conveying direction of the sheet body ST. By reciprocating the nozzle 32 in the width direction in the conveying direction at the upper surface position of the sheet body ST, the adhesive GL applied to a predetermined portion of the sheet body ST (here, the central part of the top side of the surface that is attached to the booklet) can be flattened. This allows the adhesive portion of the spin SP to be finished thin. The adhesive application operation of the adhesive application unit 30 onto the sheet ST is controlled by the operation control unit 70 based on a sheet detection signal from a sheet detection sensor (not shown) arranged on the transport path.

As shown in Figs. 4 to 6, the spin adhesive unit 40 in this embodiment includes a bobbin holder 41, a plurality of guide pulleys 42, a spin gripper 43, a linear motion mechanism 44, a spin stopper 45, a cutter 46, an air supply unit 47, and an elevation moving body 48. The bobbin holder 41 has a holding plate 41A that holds a bobbin BB around which the spin SP is wound, and a motor 41B that rotates and drives the holding plate. A circulation belt 41D is wound between a drive pulley 41C that is driven to rotate by the motor 41B and the holding plate 41A that is formed in a disk shape, and the holding plate 41A is rotated by the drive of the motor 41B, so that the spin SP can be drawn out from the bobbin BB. If the output shaft of the holding plate 41A and the motor 41B are directly connected, the configuration of the drive pulley 41C and the circulation belt 41D can be omitted.

A plurality of guide pulleys 42 are arranged inside the spin adhesive part 40. The spin SP pulled out from the bobbin BB is hung on each guide pulley 42 so as to reciprocate in the vertical direction in the internal space of the spin adhesive part 40, and then guided to the arrangement position of the spin stopper 45, which is the standby position. As shown in Figures 4 and 5, some of the guide pulleys 42 are attached to an elevation moving body 48 that moves up and down in accordance with the reciprocating motion of the linear motion mechanism 44. The elevation moving body 48 rises while the linear motion mechanism 44 is moving away from the standby position (while the spin SP is being pulled out), and then falls while the linear motion mechanism 44 returns to the standby position. By having such a guide pulley 42 attached to the elevation moving body 48, a constant tension is maintained on the spin SP even if the linear motion mechanism 44 intermittently pulls out the spin SP from the bobbin BB, so that entanglement of the spin SP in the internal space of the spin adhesive part 40 can be prevented.

The spin stopper 45 in this embodiment is disposed above the spin transport table 45A from which the spin SP is pulled out, and moves toward and away from the spin SP pulled out to the upper surface of the spin transport table 45A using a fluid cylinder 47 as a drive source. The spin transport table 45A is disposed in a position adjacent to the standby position guide 42E. Here, the planar position around the end of the standby position guide 42E becomes the standby position when pulling out the spin SP. While the spin gripper 43 moves from the standby position to the adhesion position by the operation of the linear motion mechanism 44 to pull out the spin SP from the bobbin BB, the spin stopper 45 is separated from the upper surface of the spin transport table 45A, facilitating the pulling out of the spin SP.

When the spin gripper 43 reaches the adhesion position, the fluid cylinder 47 causes the spin stopper 45 to abut against the top surface of the spin transport table 45A, clamping the spin SP together with the spin transport table 45A and applying tension to the spin SP together with the spin gripper 43. This allows the cutter 46 to cut the spin SP easily and neatly. The spin SP cut by the cutter 46 is held in a state where the required range of the tip of the spin SP, which is the tip gripping part, extends beyond the terminal end of the standby position guide 42E. This allows the spin gripper 43, which has returned to the standby position by the operation of the linear motion mechanism 44, to reliably grip the spin SP.

The spin gripper 43 in this embodiment has a head 43A attached to a linear motion mechanism 44, a pinch 43B attached to the head 43A and gripping the spin SP, and a lifting mechanism 43C for lifting and lowering the head 43A. The head 43A is attached so that it can rotate in the direction of the arrow C in FIG. 4. When the pinch 43B clamps the tip gripping portion of the spin SP that has been pulled out horizontally to the required length at the standby position of the spin gripper 43, it moves to the side of the transport unit 20, which is the adhesion position, by the linear motion mechanism 44. When the pinch 43B reaches the adhesion position, the spin stopper 45 is activated by air from the air supply unit 47, and tension is applied to the spin SP, causing it to be cut by the cutter 46.

After the tip gripping portion of the spin SP, cut to a length that matches the dimensions of the sheet body ST to be bonded, is moved to the bonding position on the sheet body ST, the head 43A rotates downward 90 degrees so that the tip gripping portion faces upward. The lifting mechanism 43C then lowers the pinch 43B along with the head 43A toward the sheet body ST, pressing the horizontal pull-out portion of the spin SP against the adhesive GL applied to the sheet body ST and bonding the tip side portion of the spin SP to the adhesive GL. The respective operations of the spin gripping body 43, the linear motion mechanism 44, the spin stopper 45 (air supply unit 47), and the cutter 46 are controlled by the operation control unit 70 based on the sheet body detection signal from a sheet body detection sensor (not shown) arranged on the transport path.

As shown in FIG. 7, the additional pressing section 50 in this embodiment is disposed between the spin adhesive section 40 and the sheet body storage section 60, and is composed of an air cylinder with a pressing plate 54 attached to the tip of the telescopic shaft 52. At least the pressing surface of the pressing plate 54 is made of a material that does not adhere to the adhesive GL. The additional pressing section 50 additionally presses the tip gripping portion of the spin SP of the sheet body ST transported on the conveyor belt 21 from the upper side of the conveyor belt 21 onto the sheet body ST. This allows the tip gripping portion of the spin SP, which was not in contact with the adhesive GL because it was gripped by the pinch 43B, to be adhered to the adhesive GL.

The additional pressing unit 50 is held by an adjuster holder 58 in which a long hole 56 is formed in the transport direction of the sheet body ST. By changing the fixed position of the additional pressing unit 50 relative to the long hole 56 of the adjuster holder 58, the additional pressing position in the transport direction can be changed, making it easy to accommodate changes in the dimensions of the sheet body ST. The additional pressing operation of the tip gripping portion of the spin SP by the additional pressing unit 50 against the adhesive GL applied to the sheet body ST is controlled by an operation control unit 70 based on a sheet body detection signal from a sheet body detection sensor (not shown) arranged on the transport path.

As shown in Figs. 7 and 8, the sheet body storage section 60 in this embodiment is disposed downstream of the additional pressing section 50 and below the conveyor belt 21. The sheet body storage section 60 in this embodiment has a rotating body 61 that rotates the sheet body ST about 90 degrees around an axis AX (arrow D in Fig. 8) extending along the conveying direction, and an upright storage body 62 that stores the sheet body ST rotated by the rotating body 61 in an upright state. The rotating body 61 repeats a rotational operation between a standby position where the sheet body ST conveyed from the additional pressing section 50 forms the same surface as the conveying surface, and a sending position to the upright storage body 62. When the sheet body ST is placed on the upper surface of the rotating body 61, the rotating body 61 rotates to the sending position, sends the sheet body ST to the upright storage body 62, and rotates to the standby position again. The operation of the rotating body 61 to send the sheet ST to the standing storage body 62 is controlled by the operation control unit 70 based on a sheet detection signal from a sheet detection sensor (not shown) arranged on the transport path.

The operation control unit 70 in this embodiment controls the operation of each of the sheet body supply unit 10, the transport unit 20, the adhesive application unit 30, the spin adhesive unit 40, the additional pressing unit 50, and the sheet body storage unit 60. The operation control unit 70 is composed of an operation control program stored in advance in a storage unit (not shown), and a CPU (not shown) that controls the operation of a specific configuration based on the operation control program. In addition, a plurality of operation units 71 are connected to the operation control unit 70. The operation unit 71 is provided with at least one of a display unit 72, an on/off switch 73, and an operation button 74, and allows the operator to display numerical information regarding the operation of the spin attachment device 100, turn the spin attachment device 100 on and off, change the size of the booklet to be attached to the spin SP, etc.

The spindle attachment device 100 according to the present invention has been described above, but the technical scope of the present invention is not limited to the above embodiment. For example, the spindle attachment device 100 in this embodiment applies gel-like adhesive GL to a predetermined location on the sheet body ST, but the adhesive GL used is not limited to gel-like adhesive, and it is also possible to adopt a form in which a sheet-like adhesive GL is attached to the sheet body ST.

In addition, in this embodiment, the spin adhesive portion 40 routes the spin SP pulled out from the bobbin BB in the vertical direction of the spin adhesive portion 40, but the manner in which the spin SP is routed within the spin adhesive portion 40 is not particularly limited.

In addition, in the present embodiment, the spin adhesive unit 40 rotates the bobbin BB using the motor 41B when pulling out the spin SP from the bobbin BB, but this is not limited to the above embodiment. It is also possible to adopt a configuration in which the bobbin BB is held by a rotatable bobbin holder 41, and the spin gripper 43 and the linear motion mechanism 44 operate to pull out the spin SP from the bobbin BB.

Furthermore, in the present embodiment, the spin attachment device 100 performs an additional pressing process by the additional pressing unit 50 after the spin adhesion unit 40 adheres the spin SP to the sheet body ST, but is not limited to this form. After the spin gripper 43 releases its grip on the spin SP, the operation control unit 70 can cause the spin gripper 43 to perform an approaching process to the sheet body ST and a rotating process, respectively, to additionally press the tip gripped portion of the spin SP that was gripped by the spin gripper 43 against the adhesive GL. In this way, if the spin gripper 43 is capable of additionally pressing the spin SP, the provision of the additional pressing unit 50 can be omitted.

In addition, the spin attachment device 100 in this embodiment is provided with an operation control unit 70 that controls all operations in the sheet body supply unit 10, the transport unit 20, the adhesive application unit 30, the spin adhesion unit 40, the additional pressure unit 50, and the sheet body storage unit 60, but is not limited to this form. It is also possible to adopt a form in which individual operation control units 70 are provided in the sheet body supply unit 10, the transport unit 20, the adhesive application unit 30, the spin adhesion unit 40, the additional pressure unit 50, and the sheet body storage unit 60.

In addition, the configuration of this embodiment described above can be appropriately combined with the modified examples described in the specification or other known configurations.
