However, the distances L1, L2, and L3 from the downstream end of the projecting pieces 517, 527, and 537 in the transport direction X are set to L1> L2> L3.

(Rotating mechanism)
The rotation mechanism 7 rotates the horizontal shaft 71 that rotatably supports the trays 51, 52, and 53 on the downstream side of the transport direction X, and rotates the trays 51, 52, and 53 up and down around the horizontal shaft 71. It has a moving plate mechanism 72 and. The trays 51, 52, and 53 are connected to the horizontal axis 71 so as to be movable in the width direction Y. Further, when the trays 51, 52, and 53 are not supported by the rotating plate mechanism 72, the trays 51, 52, and 53 are connected to the horizontal shaft 71 so as to rotate downward by their own weight.

As shown in FIG. 2, the rotating plate mechanism 72 is arranged so as to cover the upper tray 53, and is provided so as to be rotatable up and down around the horizontal axis 71, and the plate member 73. A spring 74 that supports the 73 in the home position, a motor 75 that rotates and drives the plate member 73 up and down, a position sensor 76 that detects the home position of the plate member 73, and a downward rotation of the lower tray 51. It has a stopper 77 for stopping.

FIG. 8 is an upward perspective view of the plate member 73. The plate member 73 has a plate body 730, a rotating gear portion 731 extending upward from the plate body 730, and three hooking portions 732, 733, and 734 extending downward from the plate body 730. .. The motor 75 meshes with the rotary gear portion 731. As a result, the plate member 73 rotates downward when the motor 75 rotates forward in the A direction. The hooking portions 732, 733, and 734 hook the hooking pins 518, 528, and 538 of the trays 51, 52, and 53, respectively.

The plate body 730 has a stopper 736 that penetrates the stopper opening 513 and the like of the tray 51 and the like, a knife opening 737 that the folding knife 61 penetrates during saddle stitching, and a first jogger operation in the width direction Y.

I have. The knife opening 737, the guide opening 738, and the two guide notches 739 of the plate body 730 include the knife opening 514 and the like of the tray 51 and the like, and the guide opening 515 and the like. And the two guide notches 516 and the like are provided so as to overlap each other in a plan view.

The rotating plate mechanism 72 maintains the trays 51, 52, and 53 in the “open state” shown in FIG. 2 when the plate member 73 is in the home position. Since the "open state" is the first operating state, it will be referred to as the "first operating state". In the "open state", that is, in the "first operating state", the hooking portion 732 hooks the hooking pin 518, so that the lower tray 51 is positioned so as to be flush with the transport surface 30. Since the hook pin 528 is hooked by the 733, the tray 52 in the middle stage is located at a position where the tray 52 in the middle stage is rotated upward so as to maintain a predetermined interval R with the tray 51 on the upstream side of the transport direction X. The position where the upper tray 53 is rotated upward so as to maintain a predetermined interval R with the tray 52 on the upstream side of the transport direction X due to the hooking portion 734 hooking the hook pin 538. Is located in. The predetermined interval R is set to a distance at which the conveyed paper 100 is smoothly carried in between the tray 51 and the tray 52.

Then, the rotating plate mechanism 72 operates as follows when the motor 75 rotates in the normal direction.

(1) When the plate member 73 rotates (descends) downward from the home position (first operating state), the hooking portions 732, 733, and 734 descend while hooking the hooking pins 518, 528, and 538, and then descend. Along with this, the trays 51, 52, and 53 also descend due to their own weight. Then, the lowered lower tray 51 comes into contact with the stopper 77, and the hook pin 518 is released from the hook portion 732.

(2) Further, when the plate member 73 is lowered, the hooking portions 733 and 734 are lowered while hooking the hooking pins 528 and 538, and the tray 52 in the middle stage is lowered to a position where it is flush with the transport surface 30. .. In this state, since the hooking portions 733 and 734 are still hooked by the hooking pins 528 and 538, the space between the middle tray 52 and the upper tray 53 on the upstream side of the transport direction X is maintained at a predetermined interval R. There is. This is referred to as a "second operating state".

(3) Further, when the plate member 73 is lowered, the hooking portions 733 and 734 are lowered while hooking the hooking pins 528 and 538, and the middle tray 52 is in contact with the lower tray 51 which is in contact with the stopper 77. It stops at a position substantially parallel, and the hook pin 528 is released from the hook portion 733.

(4) Further, when the plate member 73 is lowered, the hooking portion 734 is lowered while the hooking pin 538 is hooked, and the upper tray 53 is lowered to a position where it is flush with the transport surface 30. This is referred to as a "third operating state".

(5) Further, when the plate member 73 is lowered, the hooking portion 734 is lowered while hooking the hooking pin 538, and the upper tray 53 stops at a position substantially parallel to the middle tray 52, and the hooking pin 538 is released from the hook 734. This state is referred to as a "closed state" because all the trays 51, 52, and 53 are in a substantially parallel state.

In this way, the rotating plate mechanism 72 puts the three trays 51, 52, and 53 into the middle tray 52 from the home position (first operating state) in which the paper 100 can be placed on the lower tray 51. The three trays 51, 52, and 53 are abbreviated through the position where 100 can be placed (second operating state) and the position where paper 100 can be placed on the upper tray 53 (third operating state). It is designed to rotate to a parallel position (closed state). FIG. 9 is an upward perspective view showing the three trays 51, 52, and 53 in the “open state” as viewed from the upstream side in the transport direction X. FIG. 10 is an upward perspective view showing three trays 51, 52, and 53 in the “closed state” as viewed from the upstream side in the transport direction X. 11 to 13 are side view showing the three trays 51, 52, 53 in the “closed state”, FIG. 11 shows the lower tray 51, and FIG. 12 shows the middle tray 52. FIG. 13 shows the upper tray 53. As can be seen from FIGS. 11 to 13, the heights H1, H2, and H3 of the connecting positions of the trays 51, 52, and 53 with respect to the horizontal axis 71 are H1 <H2 <H3, whereby the trays 51, 52, and 53 are formed. Are almost parallel.

Further, the rotating plate mechanism 72 rotates the motor 75 in the reverse direction after the rotation operation as described above is completed, so that the plate member 73 moves upward while reducing the load of the motor 75 by the urging force of the spring 74. The three trays 51, 52, and 53 are rotated (raised) to return to the home position.

Then, when the start switch is pressed, the bookbinding device 10 operates as follows.

(1) First, the transport suction mechanism 21 operates to feed the paper 100A to the transport mechanism 3. Next, the adhesive application portion 4 operates, and the adhesive 40 (FIG. 16) is applied to the substantially central portion of the paper 100A that has passed through the transport roller pair 31 in the width direction. Then, the paper 100A coated with the adhesive 40 is carried into the mounting portion 5 by the transport rollers pairs 32 and 33. At this time, in the mounting portion 5, since the rotating plate mechanism 72 is in the home position, that is, in the “first operating state”, the paper 100A is smoothly carried in and placed on the tray 51. The paper 100A comes into contact with the stopper 736 when it is carried in. When the paper 100A is carried in, the jogger mechanism operates. That is, the first guide 81 performs a jogger operation in the width direction Y, and the two second guides 82 perform a jogger operation in the transport direction X. As a result, the paper 100A on the tray 51 is arranged.

(2) Next, when the loading work of the paper 100A on the tray 51 is completed, the rotating plate mechanism 72 is activated, the loading portion 5 is in the “second operating state”, and the transport suction mechanism 22 is entered. Is activated, and the paper 100B is sent out to the transport mechanism 3. Next, the adhesive application portion 4 operates, and the adhesive 40 is applied to the substantially central portion in the width direction of the paper 100B that has passed through the transport roller pair 31. Then, the paper 100B coated with the adhesive 40 is carried into the mounting portion 5 by the transport rollers pairs 32 and 33. At this time, since the mounting portion 5 is in the “second operating state”, the paper 100B is smoothly carried into the tray 52 and mounted. The paper 100B comes into contact with the stopper 736 when it is carried in. When the paper 100B is carried in, the jogger mechanism operates. That is, the first guide 81 performs a jogger operation in the width direction Y, and the two second guides 82 perform a jogger operation in the transport direction X. As a result, the paper 100B on the tray 52 is arranged.

(3) Next, when the work of placing the paper 100B on the tray 52 is completed, the rotating plate mechanism 72 operates, the placing portion 5 becomes the "third operating state", and the transport suction mechanism 23 Is activated, and the paper 100C is sent out to the transport mechanism 3. Then, the paper 100C that has been sent out is carried into the mounting portion 5 via the transport roller pairs 31, 32, 33 without being coated with the adhesive by the adhesive coating portion 4. At this time, since the mounting portion 5 is in the “third operating state”, the paper 100C is smoothly carried into the tray 53 and mounted. The paper 100C comes into contact with the stopper 736 when it is carried in. When the paper 100C is carried in, the jogger mechanism operates. That is, the first guide 81 performs a jogger operation in the width direction Y, and the two second guides 82 perform a jogger operation in the transport direction X. As a result, the paper 100C on the tray 53 is arranged.

(4) When the loading work of the papers 100A, 100B, 100C on the trays 51, 52, and 53 is completed as described above, the rotating plate mechanism 72 is activated and the mounting portion 5 is in the “closed state”. As a result, the sheets 100A, 100B, and 100C are in a substantially parallel state in a state of being separated from each other. Then, the jogger mechanism is activated. That is, the first guide 81 performs a jogger operation in the width direction Y, and the two second guides 82 perform a jogger operation in the transport direction X. As a result, the papers 100A, 100B, and 100C in a substantially parallel state are prepared at once.

(5) Then, the saddle stitching mechanism 6 operates. As a result, the sheets 100A, 100B, and 100C are saddle stitched as shown in FIGS. 16 to 19. That is, as shown in FIG. 16, the folding knife 61 is lowered, and as shown in FIG. 17, three sheets of paper 100 are folded by the folding knife 61, and the folding portion 110 is the introduction roller pair 62.

Since the positions of Y are arranged in the same state, the saddle stitch booklet 200A having an even edge as shown in FIG. 21 can be produced by folding the folding knife 61 as shown by the arrow A.

In this case, as described above, the jogger mechanism may be operated each time the paper is loaded into each tray, and may be operated even after the mounting portion 5 is in the "closed state". , It may be operated only after the mounting portion 5 is in the "closed state".

(a-2) As shown in FIG. 22, when the positions of the trays 51, 52, and 53 in the width direction Y are slightly deviated by the position adjusting mechanism 9, the sheets 100A, 100B, and 100C are shown in the drawings. As shown in FIG. 23, the positions in the width direction Y are arranged in a slightly deviated state. Therefore, by folding the folding knife 61 as shown by the arrow A, the saddle stitch booklet having a deviated edge as shown in FIG. 24 200B can be manufactured. According to this saddle stitch booklet 200B, the edges 2001 to 205 of each page can be used as a heading column.

In this case, in order to maintain the state in which the edges are displaced, the jogger mechanism operates only each time the paper is loaded into each tray as described above, and the mounting portion 5 is in the "closed state". Do not operate after becoming.

(B) Since the sheets 100A, 100B, and 100C are placed on the trays 51, 52, and 53, respectively, and arranged, the sheets 100A, 100B, and 100C do not come into contact with each other when they are arranged. Therefore, even if the adhesive is applied to the papers 100A and 100B, the papers 100A, 100B and 100C can be overlapped and folded to perform a complete bookbinding.

(C) Since the jogger mechanism is provided, the papers 100A, 100B, and 100C placed on the trays 51, 52, and 53 can be arranged more reliably.

(D) Since the trays 51, 52, and 53 can be positioned on the same surface as the transport surface 30 by the rotating mechanism 7, the papers 100A, 100B, and 100C transported by the transport mechanism 3 can be respectively positioned. It can be smoothly carried onto the trays 51, 52, and 53.

(E) When the lower tray 51 is located on the same surface as the transport surface 30 by the rotating mechanism 7, the middle tray 52 has a predetermined interval R between the tray 51 and the tray 51 on the upstream side in the transport direction X. Since it is located at a position rotated upward so as to be maintained, the tray 51 and the tray 52 are open toward the upstream of the transport direction X. Therefore, the paper 100A transported by the transport mechanism 3 can be carried onto the tray 51 extremely smoothly.

(F) When the tray 52 in the middle stage is positioned on the same surface as the transport surface 30 by the rotating mechanism 7, the tray 53 in the upper stage has a predetermined distance R between the tray 52 and the tray 52 on the upstream side in the transport direction X. Since the tray 52 and the tray 53 are located at a position rotated upward so as to be maintained, the tray 52 and the tray 53 are open toward the upstream of the transport direction X. Therefore, the paper 100B conveyed by the conveying mechanism 3 can be carried onto the tray 52 extremely smoothly.

(G) Since all the trays 51, 52, and 53 can be positioned substantially parallel to each other by the rotating mechanism 7, the papers 100A, 100B, and 100C placed on the trays 51, 52, and 53 can be positioned with each other. Can be maintained approximately parallel. Therefore, the folding knife 61 can be folded with high accuracy.

(H) Since all the trays 51, 52, and 53 can be rotated only by operating the rotating plate mechanism 72 of the rotating mechanism 7, the device configuration of the rotating mechanism 7 can be simplified.

(I) Since the position adjusting mechanism 9 can correct the assembly error in the width direction Y of the trays 51, 52, and 53, the sheets 100A, 100B, and 100C can be satisfactorily arranged.

(J) The position adjusting mechanism 9 can intentionally shift the positions of the trays 51, 52, and 53 in the width direction Y. Therefore, for example, a saddle stitch booklet 200B having a misaligned edge as shown in FIG. 24 can be used. Can be manufactured.

(K) According to the saddle stitching mechanism 6, since the folding portion 110 by the folding knife 61 is sandwiched by the introduction roller pair 62, the folding work and the bonding work can be satisfactorily executed.

(L) Since the pressing roller pair 63 is provided after the introduction roller pair 62, the folding work and the bonding work can be performed reliably and satisfactorily without causing wrinkles or the like.

(M) Since the folding portion 61 pressed by the pressing roller pair 63 is pressed by the pressing portion 64, the adhesive strength of the folding portion 61 can be improved.

[Another Embodiment]
(1) FIG. 25 is a schematic side sectional view showing a bookbinding device 10A according to another embodiment of the present invention. This bookbinding device 10A is different from the bookbinding device 10 of the first embodiment only in that it does not include the adhesive coating portion 4.

In the bookbinding device 10A, the saddle stitching mechanism 6 of the bookbinding device 10 operates as a folding mechanism.

According to the bookbinding device 10A, the same effect as that of the bookbinding device 10 of the first embodiment can be exhibited, but the booklets 200A, 200B, etc. that are not adhered, that is, only folded, can be manufactured.

(2) The transport suction mechanism of the paper feed unit 2 is not limited to three, and may be two or four or more depending on the number of trays of the mounting unit 5.

(3) The number of transport suction mechanisms of the paper feed unit 2 may be one. In this case, the paper needs to be placed on the paper feed tray so that the paper is sent out in the order of being carried into each tray.

(4) The number of trays of the mounting portion 5 is not limited to three, and may be two or four or more.

The bookbinding apparatus of the present invention has great industrial utility value because even paper coated with an adhesive can be overlapped and folded to perform bookbinding.
