The bookbinding apparatus includes an application device that forms an adhesive portion to which a cover can be attached by applying an adhesive to an end surface (hereinafter referred to as an adhesive surface) extending in the thickness direction of the sheet bundle. For example, the coating apparatus disclosed in Patent Document 1 includes a drum and a clamper. The drum rotates around an axis extending in the horizontal direction in a state where the drum is immersed in the molten glue as an adhesive. The clamper holds the sheet bundle with the adhesive surface facing the drum from above, and further moves horizontally along a direction perpendicular to the axial direction of the drum. The drum applies an adhesive to the bonding surface.

Japanese Patent No. 4515116

  The coating apparatus disclosed in Patent Document 1 is a drum arranged in a posture different from the above-described drum in order to attach glue to a corner portion connecting an end surface in the thickness direction and an adhesive surface in a sheet bundle. It is necessary to provide further. As a result, the mechanism of the bookbinding apparatus may be complicated.

  An object of the present invention is to provide a bookbinding apparatus capable of applying an adhesive to a bonding surface of a sheet bundle and an end surface in the sheet bundle thickness direction and a corner portion connecting the bonding surfaces with a simple mechanism. .

  A bookbinding apparatus according to an aspect of the present invention includes a holding unit that can hold a plurality of supplied sheets in a state of being stacked in a first direction, and a sheet bundle that is the plurality of sheets held by the holding unit. Among them, a paper aligning means for aligning a sheet bundle end surface, which is an end surface in a second direction orthogonal to the first direction, substantially flush along the first direction, and the first direction and the second direction, An applicator roller that can be rotated about an axis that intersects the third direction and the first direction orthogonal to the second direction and that extends perpendicular to the second direction, and an adhesive can adhere to the peripheral surface; and When the supply means capable of supplying the adhesive and the paper aligning means align the end faces of the sheet bundle, at least one of the holding means and the application roller is moved along the third direction. The application roller is moved in front of the sheet bundle end surface. A moving means for making a relative movement in a state of approaching from the second direction side; and a rotating means for rotating the application roller about the axis when the moving means relatively moves the application roller, and the application roller Is rotated around the axis while being relatively moved, so that the adhesive supplied from the supply means is applied to the end face of the sheet bundle, one end face in the first direction of the bundle of sheets, and the bundle of sheets. It applies to the 1st corner | angular part which is a part which connects an end surface.

  According to this aspect, when the moving means moves the application roller relative to the end face of the sheet bundle, the rotating means rotates the application roller, so that the centrifugal force is applied to the adhesive attached to the peripheral surface. Works. As a result, the adhesive adhering to the peripheral surface moves toward the end of the sheet bundle in the second direction (hereinafter referred to as “end of sheet bundle”). Of the rotating peripheral surface, the adhesive adhering to a portion that is substantially in the same position as the sheet bundle end face in the first direction moves to the sheet bundle end face. The application roller is arranged in a posture in which the axis intersects with the third direction and the first direction and extends perpendicular to the second direction. Of the rotating peripheral surface, a portion (hereinafter referred to as “first facing portion”) that is substantially in the same position as the first corner in the first direction rotates so as to rub the adhesive against the first corner. . Therefore, the adhesive adhered to the first facing portion moves toward the first corner portion. As described above, the adhesive adheres to the sheet bundle end face and the first corner. The bookbinding apparatus applies an adhesive to the sheet bundle end face and the first corner only by including an application roller. Therefore, the bookbinding apparatus can apply the adhesive to the bonding surface of the sheet bundle and the corners connecting the end surface and the bonding surface in the sheet bundle thickness direction with a simple mechanism.

  The rotating unit may rotate the application roller in a rotation direction in which a portion of the peripheral surface closest to the end face of the sheet bundle is directed upstream in a direction in which the application roller relatively moves. In this case, the end portion of the sheet bundle that is in contact with the portion of the rotating peripheral surface that is closest to the end face of the sheet bundle (hereinafter referred to as “proximity portion”) through the adhesive is from one end face to the one end face of the sheet bundle. It bends in the direction toward the opposite other end surface. Since the proximity portion rotates and moves toward the upstream side in the direction in which the application roller moves relative to the sheet bundle end surface, the frictional resistance generated between the proximity portion and the sheet bundle end surface is reduced. Accordingly, the end portion of the sheet bundle is easily bent smoothly in the first direction. The adhesive easily enters between a plurality of sheets forming the sheet bundle. Therefore, the bookbinding apparatus can easily apply the adhesive between the plurality of sheets forming the sheet bundle at the same time as applying the adhesive to the end face and the first corner of the sheet bundle.

  The rotating unit may rotate the application roller in a rotation direction in which a portion of the peripheral surface closest to the end face of the sheet bundle moves toward a downstream side in a direction in which the application roller relatively moves. In this case, the end portion of the sheet bundle with which the rotating proximity portion contacts via the adhesive is bent in a direction from one end surface of the sheet bundle to the other end surface facing the one end surface. The proximity portion rotates and moves toward the downstream side in the direction in which the application roller moves relative to the end face of the sheet bundle, so that the first corner portion is caused by the frictional resistance generated between the proximity portion and the end portion of the sheet bundle. Is easy to bend and is easily applied with an adhesive. Therefore, the bookbinding apparatus can apply a sufficient amount of adhesive to the first corner at the same time as applying the adhesive to the end face of the sheet bundle.

  The first direction is a vertical direction, and the supply means is formed in a box shape capable of storing the adhesive therein, and holds the application roller rotatably around the axis in the interior, A storage tank having an opening that exposes a part of the peripheral surface in a direction opposite to the second direction may be provided, and the moving unit may relatively move the storage tank together with the application roller. In this case, when the moving means moves the storage tank relative to the sheet bundle end surface together with the application roller, the rotation means rotates the application roller. As a result, a part of the peripheral surface exposed from the opening applies the adhesive stored in the storage tank to the sheet bundle end surface and the first corner. When the first direction is the vertical direction, the application roller is arranged in a posture that extends along the direction in which the axis intersects the horizontal direction. For this reason, it is unlikely that the adhesive is gradually separated from the application roller as the adhesive stored in the storage tank decreases. Regardless of the amount of the adhesive stored in the storage section and the diameter of the peripheral surface, the application roller easily comes into contact with the stored adhesive. Therefore, the bookbinding apparatus can reduce the diameter of the application roller for applying the adhesive.

  The moving means reciprocally moves the at least one to relatively move the application roller in one direction among the third directions, and then relatively move in the other direction opposite to the one direction, The rotating means normally rotates the coating roller that relatively moves in the one direction, reverses the coating roller that relatively moves in the other direction, and the coating roller rotates normally while relatively moving in the one direction. Thus, the adhesive is applied to the end face of the sheet bundle and the first corner, and reversely moved while relatively moving in the other direction, so that the end face of the sheet bundle and the one end face of the bundle of sheets are The adhesive may be applied to the opposite other end surface and the second corner portion that is a portion connecting the sheet bundle end surfaces. In this case, the moving means reciprocates the application roller relative to the end face of the sheet bundle, so that the application roller can apply the adhesive to the end face of the sheet bundle, the first corner, and the second corner. Therefore, the bookbinding apparatus can apply a sufficient adhesive to the end of the sheet bundle.

  The first direction is a vertical direction, the one end surface is an upper end surface of the sheet bundle, and the supply means is formed in a box shape capable of storing the adhesive therein, and the application is performed inside the application. A storage tank having an opening for holding a roller rotatably around the axis and exposing a part of the peripheral surface in a direction opposite to the second direction; and the moving means reciprocally moves at least one of the rollers By moving the application roller together with the storage tank in one direction among the third directions, the application roller is relatively moved in another direction opposite to the one direction. The application roller that relatively moves in the direction is rotated in a rotation direction in which the closest part is directed toward the other direction, and the application roller that is relatively moved in the other direction is rotated in the one direction side. Turn to The applicator roller is relatively movable in a posture in which the upper part of the peripheral surface is located on the other direction side than the lower part, and by rotating while relatively moving in the one direction, The adhesive is applied to the end face of the sheet bundle and the first corner, and is rotated while being relatively moved in the other direction, so that the bottom face of the sheet bundle and the upper end face of the sheet bundle are opposed to each other. You may apply | coat the said adhesive agent to the 2nd corner | angular part which is a part which connects an end surface and the said sheet bundle end surface. In this case, the application roller applies the adhesive to the first corner, and then applies the adhesive to the second corner below the first corner. Therefore, the bookbinding apparatus can make it difficult for the adhesive applied to the end of the sheet bundle to fall from the sheet bundle.

  The first direction is a vertical direction, the one end surface is an upper end surface of the sheet bundle, and the supply means is formed in a box shape capable of storing the adhesive therein, and the application is performed inside the application. A storage tank having an opening for holding a roller rotatably around the axis and exposing a part of the peripheral surface in a direction opposite to the second direction; and the moving means reciprocally moves at least one of the rollers By moving the application roller together with the storage tank in one direction among the third directions, the application roller is relatively moved in another direction opposite to the one direction. The application roller that relatively moves in the direction is rotated in a rotation direction in which the closest part is directed toward the one direction side, and the application roller that is relatively moved in the other direction is the side that is closest to the other direction side. Turn to The applicator roller is relatively movable in a posture in which the upper part of the peripheral surface is located on the one direction side with respect to the lower part, and by rotating while relatively moving in the one direction, The adhesive is applied to the end face of the sheet bundle and the first corner, and is rotated while being relatively moved in the other direction, so that the bottom face of the sheet bundle and the upper end face of the sheet bundle are opposed to each other. You may apply | coat the said adhesive agent to the 2nd corner | angular part which is a part which connects an end surface and the said sheet bundle end surface. In this case, the application roller applies the adhesive to the first corner, and then applies the adhesive to the second corner below the first corner. Therefore, the bookbinding apparatus can make it difficult for the adhesive applied to the end of the sheet bundle to fall from the sheet bundle.

  The application roller may include a plurality of recesses formed by recessing a part of the peripheral surface toward the axis. In this case, the adhesive supplied to the peripheral surface by the supply means tends to enter the inside of the recess. Therefore, the bookbinding apparatus can attach more adhesive to the peripheral surface of the application roller.

  The moving means may move the application roller among the holding means and the application roller. In this case, the application roller moves along the third direction while the holding means for holding the sheet bundle is stationary, and the adhesive is applied to the end of the sheet bundle. The bookbinding apparatus can save the space required for the holding means to move along the third direction. Therefore, the bookbinding apparatus can be reduced in size.

  The supply unit may include a heat generating element capable of generating heat, and may supply a thermoplastic adhesive that dissolves when the heat generating element generates heat to the peripheral surface. In this case, when the adhesive is applied to the end portion of the sheet bundle, the bookbinding apparatus dissolves and liquefies the adhesive by causing the heating element to generate heat. On the other hand, when the adhesive is not applied to the end portion of the sheet bundle, the bookbinding apparatus does not cause the heating element to generate heat, thereby causing the adhesive to transition to a solidified state where odor is hardly generated. Therefore, the bookbinding apparatus can suppress the generation of the odor of the adhesive.

  The movable part 401 includes a butting plate 460, a lifting motor 490, a screw shaft 491, and a second clamp 404. The screw shaft 491 extends between the front rails 417 and 418 in the vertical direction. The elevating motor 490 can rotate the screw shaft 491 about the axis. The abutting plate 460 is a rectangular plate-like body that is provided on the rear surface side of the support plate 411 and extends in the vertical direction and the horizontal direction. The abutting plate 460 is provided on the front side of the front rails 417 and 418 and on the rear side of the front rails 417 and 418 and the screw shaft 491. The vertical length of the abutting plate 460 is larger than the vertical length of the front end surface of the sheet bundle 8 on the placement surface 110A.

  The second clamp 404 can grip the booklet 10 (see FIG. 24) before cutting in which the sheet bundle 8 is wrapped with the cover sheet 9 from above and below. The second clamp 404 includes an upper clamp 470 and a lower clamp 480. The upper clamp 470 and the lower clamp 480 are opposed to each other in the vertical direction with the abutting plate 460 interposed therebetween, and selectively hold and release the booklet 10 by each raising and lowering.

  The upper clamp 470 includes a movable body 471 and a clamp body 472. The movable body 471 is a member that extends in the left-right direction from the rear side of the front rail 417 to the rear side of the front rail 418 and is movable along the front rails 417 and 418.

The clamp body 472 is a rectangular plate-like body extending in the vertical direction and the horizontal direction.

  The lower clamp 480 has the same structure as the upper clamp 470 and is substantially vertically symmetrical with the upper clamp 470. The lower clamp 480 includes a movable body 481 and a clamp body 482. However, when the screw shaft 491 rotates in one direction, the nut of the movable body 471 converts the linear motion direction in which the rotational motion of the screw shaft 491 is converted, and the nut of the movable body 481 converts the rotational motion of the screw shaft 491. The direction of linear motion is opposite to each other. The clamp body 482 is a plate-like body that is provided on the rear surface of the movable body 481 and protrudes above the movable body 481.

  The center positions in the left and right direction of the abutting plate 460 and the clamp bodies 472 and 482 are substantially the same as the center position in the left and right direction of the cover sheet 9 supplied from the cover sheet supply unit 6 and the horizontal position of the table 110 is It almost coincides with the center position. The abutting plate 460 and the clamp bodies 472 and 482 extend in the left-right direction over a range including the cover 9 supplied from the cover-sheet supply unit 6 in the left-right direction.

  With the above structure, the cover holding unit 400 can perform the following operations. With reference to FIG. 8, the raising / lowering operation | movement of the movable part 401 is demonstrated. When the transport motor 422 rotationally drives the screw shaft of the transport unit 402, the support plate 411 provided with the nut moves along the pair of guide rails 423. That is, the movable part 401 provided with the support plate 411 moves up and down. The movable portion 401 is movable upward to a position where the movable portion 401 protrudes above the main body frame 2 through the cover sheet supply port 22. The movable range of the movable part 401 includes the reference position for pasting. The sticking reference position is the vertical position of the movable portion 401 where the abutting plate 460 covers the entire sheet bundle 8 on the placement surface 110A in front view.

  With reference to FIG. 9, the raising / lowering operation | movement of the 1st clamp 403 is demonstrated. When the elevating motor 450 is driven to rotate, the connecting portion 454 moves along the rear rails 415 and 416 via the pulleys 451 and 452 and the belt 453. That is, the lower clamp 440 connected to the connecting portion 454 moves in the vertical direction. When the lower clamp 440 is not in contact with the upper clamp 430, the upper clamp 430 is held at the upper reference position. The upper reference position is a vertical position of the upper clamp 430 where a positioning projection (not shown) of the upper clamp 430 is supported by the positioning plate 455. That is, the positioning plate 455 is provided above the contact position described later, and restricts the downward movement of the upper clamp 430.

  The lower clamp 440 that moves upward contacts the upper clamp 430 located at the upper reference position from below, and moves upward while supporting the upper clamp 430. That is, the upper clamp 430 can move upward from the upper reference position by being pressed by the lower clamp 440 that moves upward. The upper clamp 430 and the lower clamp 440 move to the upper end of each movable range in a state where they are aligned in the vertical direction.

  When the lower clamp 440 moves downward from the upper end of its movable range, the upper clamp 430 supported by the lower clamp 440 moves downward to the upper reference position by its own weight. Since the upper clamp 430 that has reached the upper reference position is restricted from moving downward by the positioning plate 455, the lower clamp 440 moves away from the upper clamp 430. The lower clamp 440 that moves downward moves to the lower end of the movable range via the lower reference position. The lower reference position is a vertical position of the lower clamp 440 that is symmetrical with the upper reference position in the vertical direction across the abutting plate 460. That is, the distance from the butting plate 460 to the upper reference position and the distance from the butting plate 460 to the lower reference position are substantially the same. Note that the distance from the upper reference position to the lower reference position is slightly smaller than the vertical length of the cover sheet 9 supplied to the cover sheet holding unit 400.

  When the pair of solenoids 433 and 435 move the rear plate 431 and the front plate 432 in directions close to each other, the operation region 430A is closed. When the pair of solenoids 433 and 435 move the rear plate 431 and the front plate 432 away from each other via the opening and closing links 434 and 436, respectively, the operation region 430A is opened. Similarly, the operation area 440A is opened or closed by a pair of solenoids 443 and 445.

  With reference to FIG. 9, the raising / lowering operation | movement of the 2nd clamp 404 is demonstrated. When the lifting motor 490 rotationally drives the screw shaft 491, the movable body 471 provided with the nut moves along the front rails 417 and 418. At the same time, the movable body 481 provided with the nut moves in the direction opposite to the movable body 471 along the front rails 417 and 418. In other words, the clamp bodies 472 and 482 move vertically and symmetrically with respect to the abutting plate 460 so as to approach or separate from each other.

  The movable body 471 is movable downward to a position where it comes into contact with the upper end portion of the abutting plate 460. The movable body 481 can move upward to a position where it comes into contact with the lower end portion of the abutting plate 460. When the movable body 471 moves to the lower end of the movable range and the movable body 481 moves to the upper end of the movable range, the vertical distance between the clamp bodies 472 and 482 (that is, the gap between the clamp bodies 472 and 482). ) Is the smallest. At this time, the vertical distance between the clamp bodies 472 and 482 is smaller than the vertical length of the booklet 10.

<1-6. Cutting unit 500>
The cutting unit 500 will be described with reference to FIG. In FIG. 10, the left cutting part 510 and the right cutting part 520 are at the left end and the right end of each movable range, and the cutting members 513, 523, and 533 are at the upper end of each movable range. The cutting unit 500 is disposed on the rear side of the paper alignment unit 100 (see FIG. 3).

  As shown in FIG. 10, the cutting unit 500 includes a left cutting unit 510, a right cutting unit 520, a post cutting unit 530, and a driving unit 540. The left cutting unit 510 cuts the left end surface of the booklet 10. The right cutting unit 520 cuts the right end surface of the booklet 10. The post-cutting unit 530 cuts the rear end surface of the booklet 10. The drive unit 540 performs various operations of the left cutting unit 510, the right cutting unit 520, and the post cutting unit 530. Note that cutting the end face of the booklet 10 means separating the outer portion including the end face of the booklet 10 from the booklet 10.

  The drive unit 540 includes a base 541, a belt conveyor 542, a pair of left rails 543, a screw shaft 544, a pair of right rails 545, and a transport motor (not shown). The base 541 is a substantially square plate-like body arranged in the rear part of the main body frame 2 when viewed from the front. The belt conveyor 542 is provided at the approximate center in the left-right direction on the upper surface of the base 541 and extends over the entire front-rear direction of the base 541. A front end portion of the belt conveyor 542 protrudes to the front side of the base portion 541. The belt conveyor 542 rotates the annular belt 542A clockwise or counterclockwise in a side view. A portion of the belt 542A that moves on the upper surface side of the belt conveyor 542 is a conveyance surface.

  The pair of left rails 543 is provided on the left side of the belt conveyor 542 on the upper surface of the base 541 and extends in the left-right direction side by side in the front-rear direction. The pair of right rails 545 is provided on the right side of the belt conveyor 542 on the upper surface of the base 541 and extends in the left-right direction side by side in the front-rear direction. The screw shaft 544 is provided between the pair of left rails 543 and between the pair of right rails 545 on the upper surface of the base portion 541. The screw shaft 544 extends in the left-right direction through the belt conveyor 542 over the left end portion and the right end portion of the base portion 541. The conveyance motor of the drive unit 540 can rotate the screw shaft 544 around the axis.

  The left cutting unit 510 includes a drive motor 511, a power conversion unit 512, a cutting member 513, and a support unit 516. The support portion 516 is a member that integrally holds the members included in the left cutting portion 510, and is movable along the pair of left rails 543. The support portion 516 has a nut (not shown) through which the screw shaft 544 is inserted. A shaft extending from the drive motor 511 is connected to the power conversion unit 512. A shaft extending from the power conversion unit 512 is connected to the cutting member 513. The cutting member 513 includes a pressing member 514 and a cutting blade 515. The cutting blade 515 is a blade extending in the front-rear direction capable of cutting the booklet 10 in the vertical direction. The pressing member 514 is a member that urges the booklet 10 along the cutting blade 515 from above. The longitudinal lengths of the pressing member 514 and the cutting blade 515 are larger than the longitudinal lengths of the booklet 10.

  The right cutting part 520 has the same structure as the left cutting part 510 and is substantially bilaterally symmetrical with the left cutting part 510. The right cutting unit 520 includes a drive motor 521, a power conversion unit 522, a cutting member 523, and a support unit 526. The cutting member 523 includes a pressing member 524 and a cutting blade 525. The support portion 526 is a member that integrally holds the members included in the right cutting portion 520, and is movable along the pair of right rails 545. The support portion 526 has a nut (not shown) through which the screw shaft 544 is inserted. However, when the screw shaft 544 rotates in one direction, the nut of the support portion 516 converts the linear motion direction that converts the rotational motion of the screw shaft 544, and the nut of the support portion 526 converts the rotational motion of the screw shaft 544. The direction of linear motion is opposite to each other.

  The post-cutting unit 530 includes a drive motor 531, a power conversion unit 532, a cutting member 533, and a support unit 536. The support portion 536 is a member that integrally holds the members included in the post-cutting portion 530. A shaft extending from the drive motor 531 is connected to the power conversion unit 532. A shaft extending from the power conversion unit 532 is connected to the cutting member 533. The cutting member 533 includes a pressing member 534 and a cutting blade 535. The cutting blade 535 is a blade extending in the left-right direction that can cut the booklet 10 in the vertical direction. The pressing member 534 is a member that urges the booklet 10 along the cutting blade 535 from above. The lateral lengths of the pressing member 534 and the cutting blade 535 are larger than the lateral length of the booklet 10.

  With the above structure, when the belt conveyor 542 rotationally drives the belt 542A, the object on the conveyance surface of the belt 542A moves in the front-rear direction. When the transport motor of the drive unit 540 rotates the screw shaft 544, the support unit 516 provided with the nut moves along the pair of left rails 543. At the same time, the support portion 526 provided with the nut moves in the opposite direction to the support portion 516 along the pair of right rails 545.

  That is, the left cutting unit 510 and the right cutting unit 520 move in the direction of approaching or separating from each other symmetrically across the belt conveyor 542. When the left cutting unit 510 moves to the left end of the movable range and the right cutting unit 520 moves to the right end of the movable range, the left-right distance between the left cutting unit 510 and the right cutting unit 520 becomes the largest. . At this time, the left-right direction distance between the left cutting unit 510 and the right cutting unit 520 is larger than the left-right direction length of the booklet 10.

  When the drive motor 511 is rotationally driven, the cutting member 513 is moved in the vertical direction by the rotational motion converted by the power conversion unit 512. When the drive motor 521 is rotationally driven, the cutting member 523 is moved in the vertical direction by the rotational motion converted by the power conversion unit 522. When the drive motor 531 is rotationally driven, the cutting member 533 is moved in the vertical direction by the rotational motion converted by the power conversion unit 532.

<1-7. Bookbinding Operation of Bookbinding Device 1>
The bookbinding operation of the bookbinding apparatus 1 will be described with reference to FIGS. 13 to 18 show a configuration necessary for explaining each operation state in the left side view of the bookbinding apparatus 1. When the user inputs a bookbinding operation start instruction to the control unit 900, the following bookbinding operation is executed under the control of the control unit 900. First, the bookbinding apparatus 1 is returned to the initial state. The paper alignment unit 100, the bundle operation unit 200, the gluing unit 300, the cover holding unit 400, and the cutting unit 500 are each controlled to the initial state.

  When the paper alignment unit 100 is controlled to the initial state, the table 110 is positioned at the first transport position. The left alignment plate 130 and the right alignment plate 140 are each positioned at a separation position. The rear alignment plate 150 is positioned at the raised position and the separated position (see FIGS. 4 to 6). When the bundle operation unit 200 is controlled to the initial state, the front alignment plate 231 is positioned at the paper alignment position (see FIGS. 4 and 6). When the glue unit 300 is controlled to the initial state, the glue application unit 340 is positioned at the retracted position, and the rotation of the glue application roller 350 is stopped (see FIG. 4).

  When the cover sheet holding unit 400 is controlled to the initial state, the movable portion 401 is positioned at the reference reference position. In the first clamp 403, the upper clamp 430 is positioned at the upper reference position, and the lower clamp 440 is positioned at the lower reference position. The operation areas 430A and 440A are both closed. In the second clamp 404, the upper clamp 470 is positioned at the upper end of the movable range, and the lower clamp 480 is positioned at the lower end of the movable range (see FIGS. 8 and 9). When the cutting unit 500 is controlled to the initial state, the left cutting portion 510 is positioned at the left end portion of the movable range, and the right cutting portion 520 is positioned at the right end portion of the movable range. The cutting members 513, 523, and 533 are positioned at the upper end of each movable range (see FIG. 10).

  Next, the first printer 3 prints an image represented in the booklet on a plurality of sheets 8A. The paper supply unit 5 conveys the printed paper 8 </ b> A toward the paper alignment unit 100. The sheet 8A is discharged from the path plate 51 to the placement surface 110A by a plurality of transport rollers 56. As shown in FIGS. 4 to 6 and 11, the discharged paper 8 </ b> A falls into a region surrounded by the left alignment plate 130, the right alignment plate 140, the rear alignment plate 150, and the front alignment plate 231. Then, the sheet bundle 8 is formed on the placement surface 110A. In FIG. 11, the rear aligning plate 150 is omitted. Since the sheet 8A is slightly larger than the placement surface 110A, the sheet bundle 8 on the placement surface 110A slightly protrudes from the table 110 in the front-rear direction and the left-right direction in plan view.

  After all the sheets 8A are supplied to the placement surface 110A, the left alignment plate 130 is moved to the right from the separation position, and the right alignment plate 140 is moved to the left from the separation position. The left alignment plate 130 contacts the left end surface of the sheet bundle 8 that protrudes to the left side of the table 110. The left end surface of the sheet bundle 8 is aligned along the right surface of the left alignment plate 130. The right alignment plate 140 contacts the right end surface of the sheet bundle 8 protruding to the right side of the table 110. The right end surface of the sheet bundle 8 is aligned along the left surface of the right alignment plate 140. The left alignment plate 130 and the right alignment plate 140 urge the sheet bundle 8 from both the left and right sides so that the center position in the left-right direction of the sheet bundle 8 coincides with the substantially center position in the left-right direction of the table 110.

  The rear alignment plate 150 is moved in the forward direction from the separation position. The rear aligning plate 150 contacts the rear end surface of the sheet bundle 8 protruding to the rear side of the table 110 and biases the sheet bundle 8 forward. The rear end surface of the sheet bundle 8 is aligned along the front surface of the rear alignment plate 150. At this time, the front end surface of the sheet bundle 8 protruding to the front side of the table 110 is pressed against the rear surface of the front alignment plate 231. The front end surface of the sheet bundle 8 is aligned along the rear surface of the front alignment plate 231. As described above, the front-rear direction position of the rear surface of the front alignment plate 231 at the paper alignment position substantially coincides with the front-rear direction position of the adhesive application surface of the adhesive application roller 350. Accordingly, the front end surface of the sheet bundle 8 that has been aligned is positioned within the glue application region of the glue application unit 340.

  The following operations are executed before (or during) execution of the printing of the paper 8A and the paper alignment of the paper bundle 8 described above. As shown in FIG. 12, the second printer 4 prints an image represented on the cover of the booklet on the cover 9. In the cover sheet holding unit 400, the movable portion 401 is moved upward from the reference reference position and positioned at the receiving position. The receiving position is a vertical position of the movable portion 401 where the movable portion 401 protrudes above the main body frame 2 through the cover sheet supply port 22 (see FIG. 1).

  The upper clamp 430 and the lower clamp 440 are moved to the upper end portions of the respective movable ranges, and are positioned directly below the cover sheet supply unit 6. The operation areas 430A and 440A are both opened. The printed cover 9 is guided toward the cover supply port 22 by the cover supply unit 6. The cover sheet 9 discharged from the cover sheet supply unit 6 enters the operation area 430A of the upper clamp 430, and further enters the operation area 440A of the lower clamp 440 located immediately below the upper clamp 430.

  As shown in FIG. 13, when the lower side of the cover 9 enters the operation area 440A, the operation area 440A is closed. The lower side portion of the cover sheet 9 is gripped between the rear plate 441 and the front plate 442. The lower clamp 440 is moved downward while gripping the lower side portion of the cover sheet 9. As the lower clamp 440 moves, the upper clamp 430 moves downward to the upper reference position by its own weight in a state where the cover sheet 9 is inserted into the operation area 430A.

  After the upper clamp 430 reaches the upper reference position, the lower clamp 440 is moved away from the upper clamp 430 to the lower reference position. When the lower clamp 440 is positioned at the lower reference position, the operation area 430A is closed. The upper side portion of the cover sheet 9 is gripped between the rear plate 431 and the front plate 432. Thereby, the upper clamp 430 and the lower clamp 440 hold the cover 9 in a posture extending in the vertical direction and the horizontal direction. Thereafter, the movable portion 401 holding the cover 9 is moved downward to the reference reference position (see FIG. 14).

  On the other hand, as shown in FIG. 14, after the sheet alignment of the sheet bundle 8 is executed, the bundle operation unit 230 is moved upward from the first vertical position to the second vertical position. Further, the bundle operation unit 230 is moved backward from the first horizontal position to the second horizontal position. The second horizontal position is the front-rear direction position of the bundle operation unit 230 where the front-rear position of the front end part of the presser plate 232 and the front end part of the table 110 at the first transport position substantially coincide. The bundle operation unit 230 is moved downward from the second vertical position after reaching the second horizontal position. The lower surface of the pressing plate 232 contacts the upper surface of the sheet bundle 8 and urges the sheet bundle 8 downward. At this time, the presser plate 232 is in a position (paper presser position) that holds the vicinity of the front end portion of the sheet bundle 8 with the table 110.

  After the pressing plate 232 is moved to the paper pressing position, the glue application roller 350 is driven to rotate, and the glue application unit 340 is moved leftward from the retracted position. That is, the glue application unit 340 moves from a state where the glue application unit 340 is retracted to the right end with respect to the front end face of the sheet bundle 8 to a position facing the front end face of the sheet bundle 8 along the left-right direction. The glue application unit 340 applies the glue 7 from the front side of the sheet bundle 8 within the range of the glue application area.

  Specifically, the glue application surface of the glue application roller 350 contacts the front end surface of the sheet bundle 8 positioned and aligned by the front alignment plate 231, and the glue 7 is applied to the front end surface of the sheet bundle 8. The glue application unit 340 is reciprocated a plurality of times in the left-right direction within the movable range of the table 110. As a result, a sufficient amount of glue 7 is applied over the entire front end surface of the sheet bundle 8 to form an adhesive portion of the cover sheet 9. Thereafter, the glue application unit 340 returns to the retracted position.

  Next, the table 110 is moved forward from the first transport position, and the bundle operation unit 230 is moved forward from the second horizontal position in synchronization with the table 110. The bundle operation unit 230 is moved by the same movement distance of the table 110 at the same movement speed as the table 110. Thus, the presser plate 232 moves while sandwiching the sheet bundle 8 with the front end portion of the table 110 without changing the paper presser position. The table 110 is moved forward to the second transport position. The second transport position is a position in the front-rear direction of the table 110 where the front end surface of the sheet bundle 8 is pressed against the abutting plate 460.

  The table 110 passes through the third transfer position while moving from the first transfer position to the second transfer position. The third transport position is a front-rear direction position of the table 110 where the front end face of the sheet bundle 8 contacts the cover sheet 9. A position where the adhesive portion formed on the front end surface of the sheet bundle 8 and the cover sheet 9 contact each other is referred to as a contact position. The upper clamp 430 holds the upper side portion of the cover 9 above the contact position. The lower clamp 440 holds the lower side portion of the cover 9 below the contact position. When the table 110 reaches the third transport position, the front end surface of the sheet bundle 8 pressed by the pressing plate 232 comes into contact with the rear surface of the cover sheet 9 held by the upper clamp 430 and the lower clamp 440. The cover sheet 9 is attached to an adhesive portion formed on the front end surface of the sheet bundle 8.

  When the table 110 moves from the third transport position to the second transport position, the operation areas 430A and 440A are opened. As the table 110 moves from the third transport position to the second transport position, the upper side portion of the cover sheet 9 released from the upper clamp 430 falls out from the operation area 430A. At the same time, the lower side portion of the cover 9 released from the lower clamp 440 comes out upward from the operation area 440A. After the operation area 440A is opened, the lower clamp 440 at the lower reference position is moved to the lower end of the movable range. That is, the lower clamp 440 is moved in a direction away from the contact position after the upper and lower sides of the cover 9 are released.

  As shown in FIG. 15, when the table 110 reaches the second transport position, the front end surface of the sheet bundle 8 pressed by the pressing plate 232 is pressed against the abutting plate 460 through the cover 9. The upper clamp 470 and the lower clamp 480 are moved in directions close to each other. The clamp body 472 of the upper clamp 470 moving downward biases the cover sheet 9 against the front edge portion on the upper surface of the sheet bundle 8, and the upper portion of the cover sheet 9 is rearward along the front end surface of the sheet bundle 8. Bend it. The clamp body 482 of the lower clamp 480 that moves upward biases the cover sheet 9 against the front edge of the lower surface of the sheet bundle 8, and the lower part of the cover sheet 9 is rearward along the front end surface of the sheet bundle 8. Bend it. Thereby, the booklet 10 which is the sheet bundle 8 wrapped with the cover 9 is created. The clamp bodies 472 and 482 sandwich the front end portion of the booklet 10 from the upper and lower sides on the rear side of the abutting plate 460.

  In the present embodiment, the front end surface of the booklet 10 is bound by the cover 9. The upper side and the lower side of the images printed on the cover 9 and the paper 8A included in the booklet 10 correspond to the left side and the right side of the bookbinding apparatus 1, respectively. Accordingly, the back side, the fore edge side, the top side, and the ground side of the booklet 10 correspond to the front side, the rear side, the left side, and the right side of the bookbinding apparatus 1, respectively.

  Next, as illustrated in FIG. 16, the bundle operation unit 230 is moved upward toward the second vertical position, and the presser plate 232 is separated from the booklet 10. Further, the bundle operation unit 230 is moved backward to the second horizontal position, and the table 110 is moved from the second conveyance position toward the first conveyance position. The booklet 10 separated from the table 110 hangs downward and rearward by its own weight in a state where the front end portion of the booklet 10 is sandwiched between the clamp bodies 472 and 482.

  Next, as shown in FIG. 17, the movable unit 401 is moved upward from the sticking reference position toward the receiving position. After the movable part 401 reaches the receiving position, the table 110 is moved from the first transport position toward the second transport position. The table 110 moves to the lower side of the booklet 10 held between the clamp bodies 472 and 482. As shown in FIG. 18, after the table 110 reaches the second transport position, the movable unit 401 is moved downward from the receiving position toward the sticking reference position. The booklet 10 held between the clamp bodies 472 and 482 is placed on the placement surface 110A. Thereafter, the clamp bodies 472 and 482 are moved in directions away from each other. The clamping of the booklet 10 by the clamp bodies 472 and 482 is released.

  Next, as shown in FIG. 19, the table 110 is moved backward from the third transport position to the fourth transport position. The fourth transport position is a front-rear direction position of the table 110 where the front end portion of the belt conveyor 542 is inserted into the slit 110 </ b> B of the table 110. Further, the bundle operation unit 230 is moved downward from the second vertical position to the third vertical position. When the bundle operation unit 230 is in the third vertical position, the presser plate 232 is positioned slightly above the placement surface 110A. As a result, the front aligning plate 231 is disposed slightly in front of the booklet 10 on the placement surface 110A.

  As shown in FIG. 20, the bundle operation unit 230 is moved backward by a predetermined distance from the second horizontal position. The rear surface of the front aligning plate 231 contacts the front end surface of the booklet 10 and presses the booklet 10 to move backward. The booklet 10 moves toward the belt conveyor 542 inserted into the slit 110B, and is placed on the conveyance surface of the belt 542A. The belt conveyor 542 rotationally drives the belt 542A to convey the booklet 10 rearward to the first cutting position (see FIG. 10). The first cutting position is a front-rear direction position of the booklet 10 where the booklet 10 is positioned between the left cutting unit 510 and the right cutting unit 520.

  As shown in FIG. 21, after the booklet 10 reaches the first cutting position, the left cutting unit 510 and the right cutting unit 520 are moved in directions close to each other. At this time, the cutting members 513 and 523 pass through the upper side of the booklet 10 and are positioned at the left and right positions corresponding to the length of the booklet to be created.

  After the cutting member 513 is positioned, the cutting member 513 is moved downward from the upper end of its movable range. At this time, the pressing member 514 presses the booklet 10 from above. The cutting blade 515 is moved downward along the pressing member 514 that presses the booklet 10. The left end face side of the booklet 10 (that is, the top side portion of the booklet 10) is cut in the vertical direction. A portion separated from the booklet 10 on the left side (that is, the left side portion of the booklet 10 divided by the cutting blade 515 on the left and right) falls to the lower side of the main body frame 2. Similarly, after the cutting member 523 is positioned, the cutting member 523 is moved downward from the upper end of the movable range. The right end surface side of the booklet 10 (that is, the ground side portion of the booklet 10) is cut in the vertical direction. The part cut off to the right side from the booklet 10 (that is, the right side part of the booklet 10 divided right and left by the cutting blade 525) falls to the lower side of the main body frame 2.

  Next, as shown in FIG. 22, the left cutting part 510 and the right cutting part 520 are moved in directions away from each other up to the left end part and the right end part of each movable range. The belt conveyor 542 rotationally drives the belt 542A and conveys the booklet 10 with the left end surface and the right end surface cut back to the second cutting position. The second cutting position is a front-rear direction position of the booklet 10 at which the booklet 10 is located immediately below the cutting member 533. The booklet 10 passes through the lower side of the cutting member 533 and is positioned at the front-rear direction position corresponding to the front-rear direction length of the booklet to be created.

  After the booklet 10 reaches the second cutting position, the cutting member 533 is moved downward from the upper end of the movable range. The rear end face side of the booklet 10 (that is, the fore edge portion of the booklet 10) is cut in the vertical direction. A portion separated rearward from the booklet 10 (that is, a rear portion of the booklet 10 divided forward and backward by the cutting blade 535) falls to the lower side of the main body frame 2. As a result, the sheet bundle end face other than the front end face to which the cover sheet 9 is attached is cut out of the booklet 10 to create a booklet of a desired size.

  Thereafter, the belt conveyor 542 rotates and drives the belt 542A to convey the created booklet to a discharge position behind the second cutting position. The discharge position is located at the rear end of the cutting unit 500 and at the rear side of the main body frame 2. The user collects the prepared booklet conveyed to the discharge position.

<2-1. Gluing unit 300>
The detailed structure of the gluing unit 300 will be described with reference to FIGS. FIG. 23 is a cross-sectional view seen from the left side of a cross section that passes through substantially the center in the left-right direction of the movable portion 301 and extends in the front-rear direction and the vertical direction (the same applies to FIG. 27). Note that a lid member 348 (see FIG. 24) described later is not shown in FIG. 23 (the same applies to FIGS. 7 and 27).

  As shown in FIG. 23, the main body 349 of the gluing unit 300 includes a glue supply path 341A, a glue storage part 342, a roller installation part 343, bearing parts 344 and 345, a heater 347, and a lid member 348 (see FIG. 24). . The paste supply path 341 </ b> A is a space extending downward from the paste supply port 341. The glue storage part 342 is a substantially bottomed box-like space provided inside the main body part 349 and extending downward from the glue supply path 341A. The glue storage unit 342 can store a plurality of paste pieces (not shown) supplied from the glue supply port 341 via the glue supply path 341A. The paste piece is a solidified paste and is formed in a substantially rectangular parallelepiped shape in the present embodiment. A front wall portion 349A that forms the front side portion of the main body 349 surrounds the glue storage portion 342 from the front side, and extends inclined toward the front side where the glue application roller 350 is disposed.

  The roller installation part 343 is a space provided inside the main body part 349, and is formed on the rear side of the glue storage part 342 and on the front side of the glue application port 346. The roller installation part 343 is provided on the side opposite to the front direction (rear direction) with respect to the glue storage part 342. The roller installation part 343 communicates with the glue storage part 342 and the glue application port 346 in the front-rear direction. The bearing portion 344 is a concave portion extending downward from the center of the lower end portion of the roller installation portion 343. The bearing portion 345 is an opening that is provided on the upper surface of the main body portion 349 and on the rear side of the glue supply port 341 and communicates with the roller installation portion 343 in the vertical direction.

  The glue application roller 350 is disposed inside the main body 349 by having both ends of the shaft 353 accommodated in the bearing portions 344 and 345, and is held rotatably around the axis of the shaft 353 extending in the vertical direction. . That is, the glue application roller 350 is held by the main body 349 so as to be rotatable about the axis. Hereinafter, the axis of the glue application roller 350 is simply referred to as “axis” (the same applies to the axes of glue application rollers 2350 and 3350 described later). The axis extends in the vertical direction. In other words, the axes intersect in the left-right direction and extend perpendicular to the rear direction.

  A peripheral surface 351 </ b> A of the glue application roller 350 is disposed in the roller installation portion 343. The roller installation portion 343 exposes a part of the circumferential surface 351A from the inside of the main body portion 349 in the rearward direction. That is, the glue application roller 350 is held at a position where a part of the circumferential surface 351A is exposed from the roller installation portion 343 in the direction opposite to the front direction (backward direction). In addition, the part which roller installation part 343 exposes among the surrounding surfaces 351A corresponds with the paste application surface.

  In the front-rear direction and the left-right direction, the length of the peripheral surface 351A and the width of the roller installation portion 343 are substantially equal. That is, the glue application roller 350 substantially closes the roller installation portion 343 in the vertical direction and the horizontal direction from the rear. On the circumferential surface 351A, a plurality of peaks and valleys extending linearly along the up-down direction are alternately formed continuously along the circumferential direction (see FIG. 26). Among the plurality of crests and troughs, the plurality of troughs are a plurality of groove portions 351C formed by recessing part of the circumferential surface 351A toward the axis. Each of the plurality of groove portions 351C extends in the vertical direction in parallel with the axis. The plurality of groove portions 351C are not limited to extending in parallel with the axis. The plurality of groove portions 351C only need to extend along the axis, and for example, may extend linearly from the upper right to the lower left.

  The glue application roller 350 is held at a position where the axis passes through the roller installation portion 343 in the vertical direction. Since more than half of the circumferential surface 351A in the circumferential direction is accommodated inside (inside) the main body 349, the glue application surface is less than half of the circumferential surface 351A (see FIG. 26).

  The heater 347 is a heating element provided on the front surface of the front wall portion 349A. When the heater 347 generates heat, the plurality of pieces of paste stored in the paste storage unit 342 are dissolved and changed into liquid paste 7. That is, the glue storage unit 342 stores the glue 7 that is a thermoplastic adhesive that dissolves when the heater 347 generates heat. The glue 7 enters the inside of the plurality of groove parts 351C in the glue storage part 342 and can adhere to the peripheral surface 351A. By providing the plurality of groove portions 351 </ b> C, more glue 7 can be attached to the peripheral surface 351 </ b> A by the glue storage portion 342. The heater 347 may be provided on the rear surface of the front wall portion 349A, or may be provided on the right wall portion, the left wall portion, the upper wall portion, or the lower wall portion of the main body portion 349.

  A connecting plate 361 (see FIG. 7) that connects the main body 349 and the glue receiving installation portion 313 has a heat insulating property. Since the connecting plate 361 provided in the main body portion 349 and supporting the glue receiving / installing portion 313 has a heat insulating property, the heat generated when the heater 347 generates heat hardly propagates to the glue receiving / installing portion 313. Note that the glue receiving member 360 placed (installed) on the glue receiving installation portion 313 may be a cup disposed below the glue application roller 350 and opening upward so as to store liquid.

  As shown in FIG. 24, the lid member 348 is a plate-like body provided on the upper surface of the main body portion 349. The lid member 348 rotates around a pin 349B protruding upward from the right rear corner of the upper surface of the main body 349, thereby opening the glue supply port 341 and the glue supply path 341A, It is possible to move between a paste supply port 341 and a closed position, which is a position for closing the paste supply path 341A. The lid member 348 indicated by the solid line is located at the open position, and the lid member 348 indicated by the phantom line is located at the closed position.

  When the glue piece is supplied from the glue supply port 341 to the glue reservoir 342 via the glue supply path 341A, the lid member 348 is located at the open position, whereas when the glue piece is not supplied to the glue reservoir 342, the lid member 348 is located at the closed position. When the lid member 348 is located at the closed position, the bookbinding apparatus 1 can suppress the smell of the glue 7 stored in the glue storage part 342 from leaking outside the main body part 349.

  The bookbinding apparatus 1 may include a valve member capable of blocking communication between the glue supply port 341 and the glue storage unit 342 in the glue supply path 341A instead of the lid member 348. The valve member opens the glue supply path 341A when the glue piece is supplied to the glue supply path 341A, and closes the glue supply path 341A when the glue piece is not supplied. The bookbinding apparatus 1 may include both a lid member 348 and a valve member.

  With reference to FIGS. 4 and 23, driving modes of the transport motor 321 and the driving motor 319 will be described. The transport motor 321 and the drive motor 319 are driven and controlled by the control unit 900. The conveyance motor 321 can reciprocate the movable unit 301 along the left-right direction between a retracted position (described above) and a retracted position. When the movable part 301 (in other words, the glue application part 340) is in the retracted position, the movable part 301 is separated from the movable range of the table 110 in the left direction.

  When the transport motor 321 passes the movable range of the table 110 while the table 110 is in the first transport position, the main body portion 349 of the glue applying unit 340 has the front end of the sheet bundle ( (Hereinafter referred to as “sheet bundle end face 8 </ b> B”), it reciprocates along the left-right direction in a state of approaching from the front side. The conveyance motor 321 can change the moving speed of the main body 349 (glue application roller 350) in the left-right direction.

  The drive motor 319 can rotate the glue application roller 350 forward and backward around the axis independently of the movement of the main body 349 by the conveyance motor 321 and can change the rotation speed of the glue application roller 350. . The normal rotation is the clockwise rotation of the glue application roller 350 about the axis in plan view (see FIG. 25A), and the reverse rotation is opposite to the normal rotation of the glue application roller 350. This is rotation in the direction (see FIG. 25B).

<2-2. Detailed operation of the gluing unit 300>
With reference to FIG. 4, FIG. 7, FIG. 25 to FIG. 30, a detailed operation in which the gluing unit 300 applies the glue 7 will be described. The control unit 900 executes various drive controls of the transport motor 321 and the drive motor 319, so that the gluing unit 300 can execute various application operations. Hereinafter, as an example of various coating operations, a first coating operation, a second coating operation, a third coating operation, and a fourth coating operation will be described. The gluing unit 300 executes any one of the first application operation to the fourth application operation corresponding to the thickness of the sheet bundle 8 and the types of the plurality of sheets 8A.

  In the description of the application operation by the gluing unit 300 below, the length in the left-right direction of the sheet bundle end surface 8B is assumed to be twice the peripheral length of the peripheral surface 351A for easy understanding. In order to make the drawings easier to see, only the glue application roller 350 and the sheet bundle 8 are schematically illustrated in FIGS. 25 and 28 to 30, and a specific virtual point on the peripheral surface 351 </ b> A is illustrated as a point P. ing. However, the point P is not shown on the peripheral surface 351A at the retracted position and the retracted position. 25 and 28 to 30, for the sake of space, the distance in the left-right direction between the retracted position and the first proximity position (described later) and the distance in the left-right direction between the second proximity position (described later) and the exit position are It is shown smaller than the actual size. FIG. 26 schematically illustrates the main body 349, the glue 7, and the sheet bundle 8. In the following description, the right end portion of the sheet bundle end surface 8B is referred to as “one end portion 8C”, and the left end portion is referred to as “other end portion 8D”.

  In the present embodiment, when the gluing unit 300 is controlled to the initial state, the glue application roller 350 is located at the retracted position. Therefore, the path in which the glue application roller 350 moves in the left direction (direction from the one end 8C toward the other end 8D) is the forward path, and the path in which the glue application roller 350 moves in the right direction (direction from the other end 8D toward the one end 8C). Is the return route.

  The first application operation of the gluing unit 300 will be described with reference to FIGS. 4, 7, and 25. First, when the heater 347 controlled by the control unit 900 generates heat, the paste pieces stored in the paste storage unit 342 are melted and transitioned to the liquid paste 7. A plurality of sheets 8A supplied from the sheet supply unit 5 are held by the sheet aligning unit 100 in a state of being stacked in the vertical direction as the sheet bundle 8, and the sheet bundle end surface 8B is substantially flush. In this case, the conveyance motor 321 moves the main body 349 together with the glue application roller 350 from the retracted position to the right. At the same time, the drive motor 319 normally rotates the circumferential surface 351A at a circumferential speed substantially the same as the moving speed of the glue application roller 350 in the left-right direction. The peripheral speed of the peripheral surface 351A is the moving speed of the peripheral surface 351A rotating around the axis.

  While the main body portion 349 moves between the one end portion 8C and the other end portion 8D at a substantially constant moving speed, the glue application roller 350 is in a state of being close to the sheet bundle end surface 8B from the front side. While moving to the right, the circumferential surface 351A is rotated forward twice (see FIG. 25A). “The glue application roller 350 is close to the sheet bundle end face 8B” means that the glue application roller 350 faces the sheet bundle end face 8B at a position where the glue 7 on the peripheral surface 351A can adhere to the sheet bundle end face 8B. The case where the peripheral surface 351A contacts the sheet bundle end surface 8B is also included.

  When the peripheral surface 351A facing the sheet bundle end surface 8B rotates in the forward direction, the peripheral surface 351A to which the glue 7 is adhered in the glue storage portion 342 rotates and moves from the roller installation portion 343 to a position exposed rearward. That is, the paste 7 stored in the paste storage unit 342 flows out from the roller installation unit 343. The glue 7 adhered to the glue application surface moves to and adheres to the sheet bundle end face 8B (see FIG. 26). Thereby, the glue application roller 350 applies the glue 7 to the sheet bundle end face 8B across the one end 8C and the other end 8D.

  The position where the glue application roller 350 that was in the retracted position is close to the one end portion 8C (hereinafter referred to as “first proximity position”) and the position that is close to the other end portion 8D (hereinafter referred to as “second proximity position”). When moving to the exit position via the transfer motor 321, the transport motor 321 and the drive motor 319 temporarily stop driving. While the glue application roller 350 moves from the second proximity position to the withdrawal position, the circumferential surface 351A continues normal rotation. As a result, of the glue application surface when the glue application roller 350 is in the second proximity position, the portion located on the right side from the substantially horizontal center is rotated to the glue storage unit 342, and the glue 7 is supplied again. .

  Thereafter, the transport motor 321 moves the glue application roller 350 in the retracted position to the left, and the drive motor 319 reverses the glue application roller 350 (see FIG. 25B). The conveyance motor 321 moves the glue application roller 350 at substantially the same moving speed as when moving it to the right. The drive motor 319 reverses the circumferential surface 351 </ b> A at a circumferential speed that is substantially the same as the moving speed of the glue application roller 350. While the glue application roller 350 passes through the second proximity position and moves to the first proximity position, the glue 7 is further applied to the sheet bundle end surface 8B.

When the glue application roller 350 moves to the retracted position after passing through the first proximity position, the transport motor 321 and the drive motor 319 each temporarily stop driving, and the glue application roller 350 ends the first reciprocating movement ( (Refer FIG.25 (b)). While the glue application roller 350 moves from the first proximity position to the retracted position, the circumferential surface 351A continues to reverse. As a result, of the glue application surface when the glue application roller 350 is in the first proximity position, the portion that is on the left side from the substantially center in the left-right direction rotates to the glue storage unit 342, and the glue 7 is supplied again. .

  The transport motor 321 moves the glue application roller 350 in the retracted position again to the right, and the drive motor 319 causes the glue application roller 350 to rotate forward again (see FIG. 25C). The conveyance motor 321 moves the glue application roller 350 at substantially the same moving speed as in the first reciprocating movement. On the other hand, the drive motor 319 normally rotates the peripheral surface 351 </ b> A at a peripheral speed that is approximately twice the moving speed of the glue application roller 350. The glue application roller 350 rotates forward four times while moving from the first proximity position to the second proximity position, and the glue 7 is further applied to the sheet bundle end surface 8B (see FIG. 25C).

  The glue application roller 350 that has moved from the second proximity position to the withdrawal position stops moving in the left-right direction and normal rotation and then reverses while moving rightward again (see FIG. 25D). The transport motor 321 moves the glue application roller 350 at substantially the same moving speed as that when moving the forward path, and the drive motor 319 moves the circumferential surface 351A around twice as fast as the movement speed of the glue application roller 350. Reverse at high speed. The glue application roller 350 reverses four times while moving from the second proximity position to the first proximity position, and the glue 7 is further applied to the sheet bundle end surface 8B. When the conveyance motor 321 and the drive motor 319 stop driving, the glue application roller 350 that has moved to the retracted position ends the second reciprocating movement (see FIG. 25D).

  When the conveyance motor 321 and the drive motor 319 are further driven, the glue application roller 350 performs the third reciprocating movement in the same operation as the first reciprocating movement (see FIGS. 25E and 25F). ). By the third reciprocating movement by the glue application roller 350, the glue 7 is further applied to the sheet bundle end face 8B. The first application operation by the gluing unit 300 ends.

  As shown in FIG. 27, by performing the first application operation by the gluing unit 300, the glue 7 stored in the glue storage unit 342 is reduced, and the liquid level that is the upper end surface of the glue 7 is lowered. If the glue application roller 350 is arranged in a posture in which the axis extends along the horizontal direction, the position in the vertical direction of the liquid level of the glue 7 stored in the glue storage part 342 is lower than the lower end of the peripheral surface 351A. The main body 349 cannot supply the glue 7 to the peripheral surface 351A, and the glue application roller 350 cannot apply the glue 7. On the other hand, in the present embodiment, the glue applying roller 350 is arranged in a posture in which the axis intersects the horizontal direction (an attitude in which the axis intersects the left and right direction and extends orthogonally to the rear direction), and thus the glue that descends. 7 is difficult to separate from the glue application roller 350. Regardless of the size of the glue 7 stored in the glue storage unit 342 and the diameter of the peripheral surface 351 </ b> A, the glue application roller 350 easily contacts the glue 7. Therefore, the bookbinding apparatus 1 can reduce the diameter of the glue application roller 350 that applies the glue 7.

  Note that the glue application roller 350 is not limited to be disposed in a posture in which the axis extends in the vertical direction. As long as the glue application roller 350 is arranged in a posture in which the axis intersects in the left-right direction and is orthogonal to the front-rear direction, the glue to be stored regardless of the amount of glue 7 stored in the glue storage unit 342. 7 is easy to contact.

  Further, the front wall portion 349 </ b> A is inclined downward toward the glue application roller 350. Even when the amount of glue 7 stored in the glue storage unit 342 decreases, the remaining glue 7 is likely to move toward the glue application roller 350 along the front wall portion 349A. Regardless of the amount of glue 7 stored in the glue storage section 342 and the diameter of the peripheral surface 351A, the glue application roller 350 is more likely to come into contact with the glue 7. Therefore, the bookbinding apparatus 1 can further reduce the diameter of the glue application roller 350 that applies the glue 7.

  Since the surface area of the circumferential surface 351A is reduced by reducing the diameter of the glue application roller 350, the contact area between the glue 7 attached to the circumferential surface 351A and air is also reduced. Thereby, the odor emitted from the glue 7 adhering to the glue application surface to the outside of the main body 349 is also reduced. Therefore, the bookbinding apparatus 1 can suppress the generation of the odor of the glue 7 by reducing the diameter of the glue application roller 350.

  Of the glue 7 that has entered the plurality of grooves 351 </ b> C on the glue application surface, the glue 7 that has not adhered to the sheet bundle end surface 8 </ b> B stays in the groove 351 </ b> C and hardly drops from the glue application roller 350. The glue 7 staying in the groove part 351C returns to the glue storing part 342 again with the rotation of the peripheral surface 351A. Therefore, the bookbinding apparatus 1 can suppress leakage of the odor of the paste 7 from the main body 349.

  Of the glue 7 that has entered the inside of the plurality of grooves 351C and adhered to the peripheral surface 351A in the glue storage unit 342, the glue 7 that has fallen without being applied to the sheet bundle end surface 8B is received by the glue receiving member 360. . Since the connecting plate 361 has a heat insulating property, the heat generated when the heater 347 generates heat hardly propagates to the glue receiving installation portion 313 where the glue receiving member 360 is installed. Therefore, since the liquid paste 7 received by the paste receiving member 360 is easily cooled, it is easy to transition to a solidified state where it is difficult to generate odor. Therefore, the bookbinding apparatus 1 can suppress the generation of the odor of the glue 7.

  Since the paste application surface is less than half of the circumferential direction of the peripheral surface 351A, the amount of the glue 7 attached to the paste application surface exposed from the inside of the main body 349 is reduced. Therefore, the bookbinding apparatus 1 can suppress the generation of the odor of the glue 7.

  As described above, the glue application roller 350 that reciprocates between the retracted position and the retracted position reciprocates between the one end 8C and the other end 8D. When the glue application roller 350 that performs the first application operation reciprocates for the first time (when it moves twice between the one end 8C and the other end 8D), the drive motor 319 moves the circumferential surface 351A. Then, the glue application roller 350 is rotated forward and backward at substantially the same peripheral speed as the moving speed along the left-right direction. When the moving speed and the peripheral speed are substantially equal, the frictional resistance generated between the paste 7 immediately after being applied to the sheet bundle end surface 8B and the peripheral surface 351A in contact with the paste 7 is reduced. No wasteful load is applied to the glue 7 adhering to 8B. The glue 7 adhering to the sheet bundle end surface 8B is difficult to move and deform in the left-right direction. Therefore, the glue application roller 350 that performs the first reciprocating movement can apply the glue 7 evenly to the sheet bundle end surface 8B in the left-right direction.

  In addition, when the glue application roller 350 that has reciprocated for the first time reciprocates for the second time (when it further moves twice between the one end 8C and the other end 8D), the drive motor 319 is 351A is rotated forward and backward at a peripheral speed faster than the moving speed of the glue application roller 350. When the peripheral speed is faster than the moving speed, the glue 7 immediately after being applied to the sheet bundle end surface 8B comes into contact with the peripheral surface 351A that rotates and moves from the upstream side in the rotation direction, and is biased toward the sheet bundle end surface 8B. The As a result, the glue 7 applied by the glue application roller 350 moves in the rear direction (opposite to the front direction) together with the glue 7 applied when the glue application roller 350 reciprocates for the first time. It is easy to enter between a plurality of sheets 8A forming the sheet bundle 8. Accordingly, the bookbinding apparatus 1 can apply the glue 7 to the sheet bundle end surface 8B and simultaneously allow the glue 7 to enter between the plurality of sheets 8A forming the sheet bundle 8. Therefore, the bookbinding apparatus 1 can more firmly adhere the plurality of sheets 8A forming the sheet bundle 8 to each other.

  Further, when the glue application roller 350 that has reciprocated for the second time reciprocates for the third time (when it further moves twice between the one end portion 8C and the other end portion 8D), the drive motor 319 has a peripheral surface. 351A is rotated forward and backward at substantially the same peripheral speed as the movement speed of the glue application roller 350. As a result, the glue application roller 350 allows the glue 7 to enter the front end portion of the sheet bundle 8 and simultaneously apply the glue 7 to the sheet bundle end face 8B in the left-right direction. Since the glue 7 applied to the sheet bundle end surface 8B is equalized, the cover 9 can be more reliably bonded to the sheet bundle end surface 8B.

  In the first application operation, the drive motor 319 determines whether the adhesive application roller 350 moves in the forward path and the return path while the adhesive application roller 350 moves back and forth once. 351A is rotated at substantially the same peripheral speed. As a result, the application roller reciprocates once under the condition that the movement speed of the glue application roller 350 and the peripheral speed of the peripheral surface 351A are substantially the same, so that the glue 7 is evenly and sufficiently applied to the sheet bundle end face 8B. Is done.

  In the first application operation, the drive motor 319 causes the glue application roller 350 to move to one of the glue application rollers 350 while the glue application roller 350 continuously performs two reciprocations (for example, the second and third reciprocations). The peripheral surface 351A is rotated at different peripheral speeds when the reciprocating movement is performed and when the other reciprocating movement is performed. Accordingly, the bookbinding apparatus 1 can apply the sufficient amount of glue 7 to the sheet bundle end surface 8B and at the same time adjust the amount of glue 7 to be adhered to the sheet bundle end surface 8B so as not to be excessive.

  Further, the drive motor 319 can rotate the glue application roller 350 independently of the movement of the glue application roller 350 in the left-right direction, and the rotation speed can be varied. The drive motor 319 can rotate the glue application roller 350 at an appropriate rotation speed because sufficient glue 7 is applied to the sheet bundle end surface 8B. Therefore, the bookbinding apparatus 1 can apply a sufficient amount of glue 7 to the sheet bundle end surface 8B in accordance with the moving speed of the glue application roller 350.

  In the first application operation, the glue application roller 350 may be reciprocated any number of times. Further, for example, after the glue application roller 350 has moved three times between the one end portion 8C and the other end portion 8D, the paste application roller 350 may stop at the exit position and end the application operation.

  With reference to FIG. 28, the second application operation of the gluing unit 300 will be described by omitting the contents overlapping with the first application operation. The glue application roller 350 moves from the retracted position to the retreat position via the first proximity position and the second proximity position in the same operation as when moving in the forward path of the first reciprocation, and stops (FIG. 28). (See (a)). That is, the conveyance motor 321 moves the glue application roller 350 to the right at a movement speed that is substantially the same as that when the first reciprocation of the first application operation is performed, and the drive motor 319 has a rotation speed that is substantially the same as the movement speed. The glue application roller 350 is rotated forward at high speed. As a result, the glue 7 is applied to the sheet bundle end surface 8B.

  Thereafter, the drive motor 319 is not driven, and the transport motor 321 moves the glue application roller 350 from the retracted position to the retracted position via the second proximity position and the first proximity position (see FIG. 28B). While the glue application roller 350 moves, the glue application roller 350 does not rotate around the axis, and therefore the gluing unit 300 does not apply the glue 7 to the sheet bundle end surface 8B. The second application operation ends when the moving glue application roller 350 stops at the retracted position. The bookbinding apparatus 1 can reduce the amount of glue 7 applied to the sheet bundle end surface 8B by causing the gluing unit 300 to execute the second application operation, as compared with the case where the first application operation is executed.

  When it is required to reduce the amount of glue 7 to be applied to the sheet bundle end surface 8B due to the case where the plurality of sheets 8A are thin sheets, the sheet bundle 8 is thin, or the like, the bookbinding apparatus 1 uses the gluing unit. What is necessary is just to make 300 perform 2nd application | coating operation. Therefore, the bookbinding apparatus 1 can adjust the amount of the glue 7 applied to the sheet bundle end surface 8B according to the number and types of the plurality of sheets 8A forming the sheet bundle 8.

  The second application operation is not limited to the operation described above. That is, in the second application operation, the gluing unit 300 may not rotate the circumferential surface 351A when the glue application roller 350 moves in the forward path, but may reverse the circumferential surface 351A when moved in the backward path.

  With reference to FIG. 29, the 3rd application | coating operation | movement of the gluing unit 300 is abbreviate | omitted and the content which overlaps with a 1st application | coating operation | movement is abbreviate | omitted and demonstrated. Compared to the case of the first application operation, the conveyance motor 321 moves the glue application roller 350 in the retracted position to a retreat position through the first proximity position and the second proximity position at approximately twice the moving speed. Move while rotating forward. The drive motor 319 normally rotates the peripheral surface 351A at the same peripheral speed as that when the first reciprocation of the first application operation is performed. That is, while the glue application roller 350 moves from the first proximity position to the second proximity position, the circumferential surface 351A rotates normally once. The glue application roller 350 that has moved to the withdrawal position stops (see FIG. 29A). Compared to the case where the circumferential surface 351A rotates twice forward while the glue application roller 350 moves from the first proximity position to the second proximity position, the amount of glue 7 that the circumferential surface 351A applies to the sheet bundle end surface 8B is as follows. Reduced. Further, as compared with the case of the first application operation, the time required for the glue application roller 350 to move in the forward path is shortened. Therefore, the bookbinding apparatus 1 can speed up the coating operation.

  Thereafter, the glue application roller 350 at the retreat position is operated in the same manner as when moving in the return path in the first reciprocation of the first application operation, and reaches the retreat position via the second proximity position and the first proximity position. Move while reversing. While the glue application roller 350 moves from the second proximity position to the first proximity position, approximately the same amount of glue 7 as when the glue application roller 350 moves in the return path in the first reciprocation of the first application operation, It is further applied to the sheet bundle end face 8B (see FIG. 29B).

  When the glue application roller 350 that has moved to the retracted position stops, the glue unit 300 ends the third application operation (see FIG. 29B). The bookbinding apparatus 1 causes the gluing unit 300 to execute the third application operation, thereby increasing the amount of glue 7 that is greater than when the second application operation is performed and less than when the first application operation is performed. It can be applied to the sheet bundle end face 8B.

  With reference to FIG. 30, the fourth application operation of the gluing unit 300 will be described by omitting the contents overlapping with the first application operation. The glue application roller 350 is operated in the same manner as when moving in the forward path in the first reciprocation of the first application operation, and normally rotates from the retracted position to the exit position via the first proximity position and the second proximity position. It moves and stops (refer Fig.30 (a)).

  Thereafter, the transport motor 321 moves the glue application roller 350 to the right at substantially the same moving speed as when the first reciprocation of the first application operation is performed, and the drive motor 319 moves the speed of the glue application roller 350. The circumferential surface 351A is reversely rotated at a circumferential speed approximately twice that (see FIG. 30B). That is, the drive motor 319 rotates the circumferential surface 351A at different circumferential speeds when the glue application roller 350 moves in the forward path and when it moves in the backward path. The glue application roller 350 causes the glue 7 to enter the front end portion of the sheet bundle 8 while applying the glue 7 to the sheet bundle end surface 8B.

  When the glue application roller 350 that has moved to the retracted position stops, the fourth application operation of the glue unit 300 ends. By performing the fourth application operation, the paste 7 equivalent to the case where the third application operation is performed is applied to the front end portion of the sheet bundle 8, and at the same time, the paste 7 is also applied between the plurality of sheets 8A. Enters.

  The gluing unit 300 performs the first application operation to the fourth application operation, so that when the glue application roller 350 moves in the forward path and the return path, the movement speed of the glue application roller 350 and the peripheral speed of the peripheral surface 351A are set. Various changes can be made. The bookbinding apparatus 1 can more flexibly adjust the amount of glue 7 applied to the sheet bundle end surface 8B depending on the type and number of sheets 8. Further, by changing the moving speed of the glue application roller 350, the bookbinding apparatus 1 can speed up the application operation of the glue 7 by the gluing unit 300 as necessary.

<2-3. Example of First Modification of Gluing Unit 300>
With reference to FIG. 31, the 1st modification of the gluing unit 300 is illustrated. In the following description, the same components as those of the gluing unit 300 are denoted by the same reference numerals, description thereof will be omitted, and only differences from the above-described movable unit 301 will be described. In addition, illustration of the conveyance part 302 is abbreviate | omitted in FIG.

  The gluing unit 1300 of the first modification includes a movable part 1301 and a transport part 302 (see FIG. 4). The movable part 1301 includes a support part 1311, a nut (not shown), a glue application part 1340, a glue receiving member 1360, and a pump drive mechanism 1380. The support portion 1311 is a rectangular plate-like body extending in the vertical direction and the horizontal direction. The nut of the movable portion 1301 is provided at the lower front end portion of the support portion 1311 and the screw shaft 322 (see FIG. 4) is inserted. Accordingly, the transport motor 321 (see FIG. 4) can move the movable portion 1301 along the left-right direction.

  The glue application unit 1340 includes a main body 1349. The main body 1349 is a substantially rectangular parallelepiped box-like body that is long in the vertical direction. A heater 347 (see FIG. 23) is provided inside the main body 1349. The roller installation portion 1343 formed on the rear side of the main body 1349 has a part (glue application surface) of the peripheral surface 351A of the glue application roller 350 that is rotatably held inside the main body 1349 facing backward. It is exposed.

  The glue receiving member 1360 is a bottomed box-like body that opens on the upper side, and is provided at the lower end of the main body 1349. The space formed inside the glue receiving member 1360 includes the glue application surface of the glue application roller 350 in plan view.

  The pump drive mechanism 1380 includes a tank member 1383, a communication member 1381, a screw pump 1385, pulleys 1357 and 1358, a belt 1356, and a piping member 1387. The tank member 1383 is a substantially rectangular parallelepiped box-like body that is long in the vertical direction. The tank member 1383 is disposed on the left side of the main body 1349 and extends from the lower end of the glue receiving member 1360 to above the main body 1349 in the vertical direction.

  The communication member 1381 is a box-like body connected to the left side portion of the glue receiving member 1360 and the rear side portion of the tank member 1383. The communication member 1381 allows the glue receiving member 1360 to communicate with a space (hereinafter referred to as a delivery unit) formed inside the tank member 1383.

  The screw pump 1385 includes a shaft portion 1385A and a spiral portion 1358B. The shaft portion 1385A is a cylindrical body that extends through the tank member 1383 in the vertical direction. The spiral portion 1358B is a plate-like body provided on the peripheral surface of the shaft portion 1385A and formed in a spiral shape along the axis of the shaft portion 1385A. The spiral portion 1358B is disposed in the delivery portion.

  The pulley 1357 is provided on the shaft portion 1385A above the tank member 1383. The pulley 1358 is provided at the tip of the drive shaft of the pump drive motor 1350 provided on the front surface of the support portion 1311. The pulleys 1357 and 1358 are arranged at substantially the same height. The belt 1356 is stretched over pulleys 1357 and 1358 through a notch 1311A provided in the support portion 1311.

  The piping member 1387 is connected to the front side portion of the tank member 1383 and a plate-like body 1349A provided on the upper side portion of the main body portion 1349. The piping member 1387 communicates the delivery part with the glue supply port 341 (see FIG. 23) provided on the upper surface of the main body part 1349. That is, the piping member 1387 makes the delivery part and the glue storage part 342 communicate with each other.

  With the above-described structure, when the glue application surface applies the glue 7 to the sheet bundle end surface 8B while the movable portion 1301 moves in the left-right direction, the glue 7 falling from the glue application surface does not move inside the glue receiving member 1360. Enter from above. That is, the glue receiving member 1360 receives, under the glue application roller 350, the glue 7 that falls outside the roller setting part 1343 among the glues 7 that have entered the plurality of groove parts 351 </ b> C in the glue storage part 342. .

  The glue 7 that has entered the inside of the glue receiving member 1360 flows to the delivery unit via the communication member 1381 and is stored. In this case, the pump drive motor 1350 rotates the screw pump 1385 around the shaft portion 1385A via the belt 1356 and the pulleys 1357 and 1358. As the screw pump 1385 rotates, the spiral portion 1358B transports the glue 7 accumulated in the delivery portion upward. The glue 7 transferred by the spiral part 1358B passes through the piping member 1387 and is sent to the glue storage part 342.

  The pump drive mechanism 1380 collects the liquid glue 7 falling on the glue receiving member 1360 and sends it to the glue storage unit 342. Since the glue 7 that has been dropped without being applied to the sheet bundle end surface 8B and the glue 7 that has fallen from the glue application surface after the application operation has been completed are less likely to stay outside the main body 1349, the bookbinding apparatus 1 uses the glue 7 Odor generation can be suppressed.

<2-4. Example of Second Modification of Gluing Unit 300>
With reference to FIGS. 32-34, the 2nd modification of the gluing unit 300 is illustrated. In the following description, the same components as those of the above-described gluing unit 300 are denoted by the same reference numerals, and the description will be simplified, and only differences from the above-described movable unit 301 will be described. Note that the table 110 shown in FIG. 32 is located at the first transport position. In FIGS. 33 and 34, the glue application rollers 2350 and 3350, the glue 7, and the sheet bundle 8 are schematically illustrated. Furthermore, in the following description, the left direction is referred to as “one direction” and the right direction is referred to as “other direction”. The other direction is opposite to one direction.

  A gluing unit 2300 according to the second modification includes a movable unit 2301 and a transport unit 302. The movable portion 2301 is different from the movable portion 301 only in the arrangement posture, and has the same structure as the movable portion 301. The movable part 2301 includes a support part 2311, a glue application part 340, a drive motor 319 (see FIG. 23), and a glue receiving installation part 313.

  The support portion 2311 is a plate-like body that is arranged in a posture in which the longitudinal direction is inclined with respect to the vertical direction when viewed from the front. The glue application unit 340 and the drive motor 319 are provided in the support unit 2311. The main body 349 is formed in a box shape that can store the paste 7 therein.

  The main body 349 includes a glue storage unit 342 (see FIG. 23) and a roller installation unit 343. The glue storage part 342 is formed inside the main body part 349 and can store a plurality of paste pieces (not shown) to be supplied. The plurality of paste pieces transition to liquid paste 7 when the heater 347 (see FIG. 23) provided on the front wall 349A of the main body 349 generates heat.

  The roller installation part 343 is a space formed inside the main body part 349 and behind the glue storage part 342. A glue application roller 2350 is rotatably held on the roller installation portion 343. The glue application roller 2350 has the same configuration as the glue application roller 350.

  The glue application roller 2350 is arranged in such a posture that the upper side portion of the peripheral surface 2351A is positioned on the other direction side (right side) than the lower side portion. The axis of the glue application roller 2350 intersects with the left-right direction and the up-down direction, and extends perpendicular to the front-rear direction. In other words, the glue application roller 2350 is rotatable about an axis that intersects the horizontal direction and the vertical direction perpendicular to the vertical direction and the rear direction and extends perpendicular to the rear direction. A part (glue application surface) of the peripheral surface 2351A of the adhesive application roller 2350 is exposed from the roller installation portion 343 in the backward direction opposite to the forward direction. The peripheral surface 2351A extends from below to above the sheet bundle 8.

  The glue storage part 342 of the main body part 349 can supply the glue 7 to the peripheral surface 2351A. A groove 2351C is formed on the peripheral surface 2351A. The groove 2351C is a recess formed by a part of the peripheral surface 2351A being recessed toward the axis, and extends linearly in parallel with the axis of the glue application roller 2350. By allowing the glue 7 to enter the inside of the groove portion 2351 </ b> C, sufficient glue 7 can be attached to the peripheral surface 2351 </ b> A at the glue storage portion 342. The peripheral surface 2351A may include a plurality of concave portions such as a substantially circular shape, a substantially semicircular shape, or a substantially polygonal shape instead of the plurality of groove portions 2351C. Further, the peripheral surface 2351A may be curved in a flat shape without a recess. A substantially circular shape, a substantially semicircular shape, or a substantially polygonal concave portion and a plurality of groove portions 2351C may not be provided.

  The drive motor 319 is connected to the glue application roller 2350 via a chain 316 and pulleys 317 and 318 (see FIG. 7). The drive motor 319 can rotate the glue application roller 2350 forward and backward. The drive motor 319 can change the rotational speed of the glue application roller 2350. The glue receiving installation portion 313 is connected and fixed to the lower side of the main body portion 349 via a connection plate 361 (see FIG. 7). A glue receiving member 360 can be placed on the glue receiving installation portion 313.

  The conveyance unit 302 includes a conveyance motor 321 and a screw shaft 322. The transport motor 321 can rotate around a shaft center of a screw shaft 322 extending in the left-right direction. The screw shaft 322 is inserted through a nut (not shown) provided at the lower end of the front surface of the support portion 2311. The conveyance motor 321 moves the movable unit 2301 along the left-right direction by rotating the screw shaft 322. As the movable part 2301 moves, the main body part 349 moves the glue application roller 2350 closer to the sheet bundle end surface 8B (see FIG. 26) held by the paper aligning unit 100 from the front side. It can move along the left-right direction. In other words, the conveyance motor 321 moves the glue application roller 2350 along the left-right direction among the paper aligning unit 100 that holds the paper bundle 8 and the glue application roller 2350, so that the glue application roller 2350 is moved to the sheet bundle end surface 8B. It is possible to move relative to it. The movable range of the movable unit 2301 is substantially the same as the movable range of the movable unit 301.

  With reference to FIG. 33, the operation in which the gluing unit 2300 applies the glue 7 to the sheet bundle 8 will be described. In the following description, the front end portion of the sheet bundle 8 is referred to as “end portion 8E of the sheet bundle 8”, and the upper end surface of the sheet bundle 8 (one end surface in the vertical direction of the sheet bundle 8) is referred to as “upper end surface”. The lower end surface of the sheet bundle 8 (the other end surface in the vertical direction of the sheet bundle 8) is referred to as “lower end surface 8G”. The lower end surface 8G faces the upper end surface 8F. Further, a portion connecting the sheet bundle end surface 8B and the upper end surface 8F is referred to as a “first corner portion 8H”, and a portion connecting the sheet bundle end surface 8B and the lower end surface 8G is referred to as a “second corner portion 8I”.

  The paper aligning unit 100 at the first transport position holds the plurality of sheets 8A supplied from the sheet supply unit 5 in a state of being stacked in the vertical direction as the sheet bundle 8, and the sheet bundle end surface 8B is substantially flush. When they are aligned, the transport motor 321 moves the movable unit 2301 in one direction (left direction). The main body 349 moves in one direction from the retracted position. At the same time, the drive motor 319 normally rotates the peripheral surface 2351A at the same peripheral speed as the movement speed of the glue application roller 2350.

  The glue application roller 2350 located at the retreat position passes through the first proximity position and rotates forward while moving toward the second proximity position (see FIG. 33A). As the peripheral surface 2351A rotates in the forward direction, the glue 7 attached to the peripheral surface 2351A in the paste storage portion 342 rotates and moves from the roller installation portion 343 to a position exposed rearward.

  The glue 7 adhering to the glue application surface moves toward the end 8E of the sheet bundle 8 due to the centrifugal force. The glue 7 attached to a portion (hereinafter referred to as an “end face facing portion”) at substantially the same height as the sheet bundle end face 8B in the glue application surface moves rearward and adheres to the sheet bundle end face 8B.

  The glue 7 attached to a portion (hereinafter, referred to as “first facing portion”) at substantially the same height as the first corner portion 8H in the peripheral surface 2351A moves rearward. Here, since the glue application roller 2350 is arranged in a posture in which the axis intersects the left and right direction and the up and down direction and extends perpendicularly to the rear direction, the first facing portion is glued to the first corner portion 8H. Rotate to rub 7 The glue 7 adhered to the first facing portion moves to the first corner portion 8H. Accordingly, the glue 7 adheres to the sheet bundle end surface 8B and the first corner 8H. Therefore, the glue application roller 2350 moves from the first proximity position to the second proximity position, so that the glue 7 is applied to the sheet bundle end surface 8B and the first corner 8H in the left-right direction (FIG. 33A). )reference).

  Here, the end portion 8E of the sheet bundle 8 with which the normally rotating glue application surface contacts via the glue 7 bends downward (in the direction from the upper end face 8F toward the lower end face 8G). The portion of the rotating circumferential surface 2351A that is closest to the sheet bundle end surface 8B (hereinafter referred to as “proximity portion”) is the upstream side in the direction in which the glue application roller 2350 moves relative to the sheet bundle end surface 8B (the other direction side). Move in the direction toward). Accordingly, since the frictional resistance generated between the proximity portion and the sheet bundle end surface 8B is reduced, the end portion 8E of the sheet bundle 8 is easily bent smoothly in the vertical direction. As a result, at the end 8E of the sheet bundle 8, the plurality of sheets 8A are easily separated from each other. Therefore, the glue 7 applied to the sheet bundle end surface 8B easily enters between the plurality of sheets 8A.

  When the glue application roller 2350 moves while rotating forward to the retracted position, the transport motor 321 and the drive motor 319 stop driving, and the glue application roller 2350 stops operating. Thereafter, the conveyance motor 321 moves the main body 349 in the other direction (right direction). The glue application roller 2350 moving in the other direction moves at substantially the same moving speed as when moving in one direction (left direction). At the same time, the drive motor 319 reverses the circumferential surface 2351A at a circumferential speed substantially the same as the moving speed of the glue application roller 2350 (see FIG. 33B).

  As in the case of moving from the first proximity position to the second proximity position, the glue application roller 2350 passing through the second proximity position and moving toward the first proximity position is applied to the end portion 8E of the sheet bundle 8. Apply glue 7. More specifically, the glue 7 attached to the end face facing portion moves to the sheet bundle end face 8B. At the same time, a portion (hereinafter referred to as “second opposing portion”) of the paste application surface that is substantially the same height as the second corner portion 8I rotates so as to rub the glue 7 against the second corner portion 8I. . The glue 7 adhered to the second facing portion moves to the second corner portion 8I. As a result, the glue 7 adheres to the sheet bundle end surface 8B and the second corner 8I. Accordingly, as the glue application roller 2350 moves from the second proximity position to the first proximity position, the glue 7 is applied to the sheet bundle end surface 8B and the second corner 8I in the left-right direction (FIG. 33B). )reference).

  Similar to the case where the glue application roller 2350 moves toward the second proximity position, the peripheral surface 2351A that moves toward the first proximity position causes the end portion 8E of the sheet bundle 8 that contacts via the glue 7 to move up and down. Is smoothly bent upward (in the direction from the lower end surface 8G toward the upper end surface 8F). At the end 8E of the sheet bundle 8, the plurality of sheets 8A are easily separated from each other. Accordingly, the glue 7 applied to the sheet bundle end surface 8B easily enters between the plurality of sheets 8A.

  When the glue application roller 2350 that has moved from the second proximity position to the first proximity position moves while reversing to the retracted position, the gluing unit 2300 ends the application operation. Note that when the application operation is performed, the glue 7 falling from the peripheral surface 2351A falls to the glue receiving member 360. The glue 7 that falls from the glue application surface at the end of the application operation also falls on the glue receiving member 360. The glue 7 that has fallen on the glue receiving member 360 transitions to a solidified state where odor is unlikely to occur.

  In the application operation by the glue application roller 2350, the glue 7 is applied in the order of the first corner 8H and the second corner 8I below the first corner 8H. Therefore, the bookbinding apparatus 1 can prevent the glue 7 applied to the end 8E of the sheet bundle 8 from dripping.

  As the gluing unit 2300 performs the above-described application operation, the glue 7 stored in the glue storage unit 342 decreases (see FIGS. 23 and 27). Even in this case, since the liquid surface of the glue 7 moves downward, the peripheral surface 2351A and the glue 7 are not easily separated. The bookbinding apparatus 1 can reduce the diameter of the glue application roller 2350.

  The bookbinding apparatus 1 moves the glue application roller 2350 in the left-right direction with respect to the stationary sheet bundle 8 held by the paper alignment unit 100. Since the bookbinding apparatus 1 moves only the glue application roller 2350 among the paper alignment unit 100 and the glue application roller 2350, the space required for the paper alignment unit 100 to move along the left-right direction can be saved. Therefore, the bookbinding apparatus 1 can be reduced in size.

  Note that the application operation of the gluing unit 2300 is not limited to the operation described above. The gluing unit 2300 may perform a coating operation similar to the first coating operation to the fourth coating operation of the gluing unit 300 described above. For example, when the glue application unit 2300 performs the above-described fourth application operation and the glue application roller 2350 moves in the return path, the peripheral surface 2301A is reversed at a peripheral speed that is approximately twice the moving speed of the glue application roller 2350. Accordingly, the reverse glue application surface rotates so as to rub the glue 7 more against the second corner 8I. Therefore, a larger amount of glue 7 is applied to the second corner portion 8I.

  The bookbinding apparatus 1 is not limited to moving only the glue application roller 2350 in the left-right direction among the glue application roller 2350 and the paper alignment unit 100. For example, the bookbinding apparatus 1 may move only the paper alignment unit 100 in the left-right direction. In this case, the glue 7 application operation is performed by moving in the left-right direction with the sheet bundle end face 8B facing the glue application surface of the glue application roller 2350 that rotates only without changing the position in the left-right direction. Is done. Further, the bookbinding apparatus 1 may execute the glue 7 application operation by moving both the glue application roller 2350 and the paper alignment unit 100 in the left-right direction.

  The glue application roller 2350 of the movable part 2301 is not limited to be arranged in a posture in which the upper part of the peripheral surface 2351A is located on the other side (right side) than the lower part. Hereinafter, with reference to FIG. 34, a modified example of the arrangement posture of the glue application roller 2350 will be described. The glue application roller 3350 shown in FIG. 34 has the same configuration as the glue application roller 2350, and only the arrangement posture is different.

  The glue application roller 3350 is arranged in such a posture that the upper side portion of the peripheral surface 3351A is positioned on one side (left side) with respect to the lower side portion. The gluing unit provided with the gluing application roller 3350 is the same as the gluing unit 2300 described above, and a detailed description of the configuration is omitted.

  The operation of the glue application roller 3350 for applying the glue 7 will be described by omitting the same contents as those of the above-described application operation of the glue application roller 2350. The glue applying roller 3350 moves in one direction from the retracted position to the retracted position, and at the same time, the peripheral surface 3351A reverses at a speed substantially equal to the moving speed of the glue applying roller 2350.

  As the glue application roller 3350 moves from the first proximity position to the second proximity position, the glue 7 is applied to the sheet bundle end surface 8B and the first corner 8H in the left-right direction. The end 8E of the sheet bundle 8 with which the reverse paste application surface contacts via the paste 7 bends downward (in the direction from the upper end surface 8F toward the lower end surface 8G). The rotating proximity portion moves in a direction toward the downstream side (one direction side) in the direction in which the glue application roller 3350 moves relative to the sheet bundle end surface 8B. Due to the frictional resistance generated between the proximity portion and the end 8E of the sheet bundle 8, the first corner 8H of the sheet bundle 8 is easily bent downward. Since the rotating first opposing portion easily rubs the glue 7 to the first corner 8H, sufficient glue 7 adheres to the first corner 8H.

  The glue application roller 3350 that has passed through the second proximity position and moved to the withdrawal position stops moving in one direction (left direction) and reverse, and then starts moving in the other direction (right direction) and at the same time moves And forward rotation at approximately the same peripheral speed. The glue application roller 3350 moving from the second proximity position toward the first proximity position applies the glue 7 to the end portion 8E of the sheet bundle 8 in the same manner as when moving from the first proximity position toward the second proximity position. Apply. Here, the rotating proximity portion moves in the direction toward the downstream side (the other direction side) in the direction in which the glue application roller 3350 moves relative to the sheet bundle end surface 8B. Due to the frictional resistance generated between the proximity portion and the end portion 8E of the sheet bundle 8, the second corner portion 8I of the sheet bundle 8 is easily bent upward. Since the rotating second opposing portion easily rubs the glue 7 to the second corner 8I, sufficient glue 7 adheres to the second corner 8I. When the glue application roller 3350 moves while rotating forward from the second proximity position to the retracted position, the gluing operation ends.

  In the application operation by the glue application roller 3350, the glue 7 is applied in the order of the first corner part 8H and the second corner part 8I, so that the bookbinding apparatus 1 drips the glue 7 applied to the end part 8E of the sheet bundle 8. It can be difficult.

<3. Examples of effects of the present disclosure>
Hereinafter, the effects of the present disclosure will be exemplified. The parentheses noted in the following configuration indicate the corresponding configuration of the present disclosure.

(1) Effects of First Disclosure Conventionally, a bookbinding apparatus that performs bookbinding by binding a sheet bundle with a cover and binding a booklet is known. The bookbinding apparatus includes an application device that forms an adhesive portion to which a cover can be attached by applying an adhesive to an end surface (hereinafter referred to as an adhesive surface) extending in the thickness direction of the sheet bundle. The coating apparatus disclosed in Japanese Patent No. 4515116 includes a drum and a clamper. The drum rotates around an axis extending in the horizontal direction in a state where the drum is immersed in the molten glue as an adhesive. The clamper holds the sheet bundle with the adhesive surface facing the drum from above, and further moves horizontally along a direction perpendicular to the axial direction of the drum. The drum applies an adhesive to the bonding surface.

  In the above prior art, in order to adhere glue to the corner portion connecting the end face in the thickness direction and the adhesive surface in the sheet bundle, it is necessary to further include a drum arranged in a different posture from the drum. There is. As a result, the mechanism of the bookbinding apparatus may be complicated. In view of such a problem, the first disclosure has the following configuration.

(1-1) The bookbinding apparatus (bookbinding apparatus 1) includes a holding unit (paper aligning unit 100) capable of holding a plurality of supplied sheets (paper 8A) in a state of being stacked in a first direction (vertical direction). Of the sheet bundle (sheet bundle 8) that is the plurality of sheets held by the holding means, a sheet bundle end surface (sheet bundle) that is an end surface in a second direction (forward direction) orthogonal to the first direction A paper aligning means (paper aligning unit 100) for aligning the end face 8B) substantially along the first direction, a third direction (left-right direction) orthogonal to the first direction and the second direction, and the An application roller (adhesive application) that can be rotated about an axis that intersects the first direction and extends orthogonally to the second direction, and that allows adhesive (glue 7) to adhere to the peripheral surfaces (peripheral surfaces 2351A and 3351A). Roller 2350, 3350) and supplying the adhesive to the peripheral surface When the sheet feeding means and the sheet aligning means align the end face of the sheet bundle substantially flush, at least one of the holding means and the application roller is moved along the third direction. Thus, when the application roller relatively moves the application roller relative to the end face of the sheet bundle from the side in the second direction, the movement means relatively moves the application roller. And a rotating means (drive motor 319) for rotating the application roller around the axis. The application roller rotates about the axis while relatively moving, so that the adhesive supplied from the supply means can be used to transfer the sheet bundle end surface and one end surface of the sheet bundle in the first direction ( The upper end surface 8F) and the first corner portion (first corner portion 8H) which is a portion connecting the end face of the sheet bundle are applied.

  According to this configuration, when the moving unit moves the application roller relative to the end face of the sheet bundle, the rotating unit rotates the application roller, so that the centrifugal force is applied to the adhesive attached to the peripheral surface. Works. As a result, the adhesive adhered to the peripheral surface moves toward the end of the sheet bundle. Of the rotating peripheral surface, the adhesive adhering to a portion that is substantially in the same position as the sheet bundle end face in the first direction moves to the sheet bundle end face. The application roller is arranged in a posture in which the axis intersects with the third direction and the first direction and extends perpendicular to the second direction. Among the rotating peripheral surfaces, the first facing portion rotates so as to rub the adhesive against the first corner portion. Therefore, the adhesive adhered to the first facing portion moves toward the first corner portion. As described above, the adhesive adheres to the sheet bundle end face and the first corner. The bookbinding apparatus applies an adhesive to the sheet bundle end face and the first corner only by including an application roller. Therefore, the bookbinding apparatus can apply the adhesive to the bonding surface of the sheet bundle and the corners connecting the end surface and the bonding surface in the sheet bundle thickness direction with a simple mechanism.

  (1-2) The rotating means rotates the application roller in a rotation direction in which the portion of the peripheral surface closest to the end face of the sheet bundle moves toward the upstream side in the direction in which the application roller relatively moves. Also good. According to this configuration, the end portion of the sheet bundle that contacts the end face of the rotating sheet closest to the end face of the sheet bundle (hereinafter referred to as “proximity portion”) via the adhesive is from one end face of the sheet bundle. It bends in a direction toward the other end surface facing the one end surface. Since the proximity portion rotates and moves toward the upstream side in the direction in which the application roller moves relative to the sheet bundle end surface, the frictional resistance generated between the proximity portion and the sheet bundle end surface is reduced. Accordingly, the end portion of the sheet bundle is easily bent smoothly in the first direction. The adhesive easily enters between a plurality of sheets forming the sheet bundle. Therefore, the bookbinding apparatus can easily apply the adhesive between the plurality of sheets forming the sheet bundle at the same time as applying the adhesive to the end face and the first corner of the sheet bundle.

When the first direction is the vertical direction, the application roller is arranged in a posture that extends along the direction in which the axis intersects the horizontal direction. For this reason, it is unlikely that the adhesive is gradually separated from the application roller as the adhesive stored in the storage tank decreases. Regardless of the amount of the adhesive stored in the storage section and the diameter of the peripheral surface, the application roller easily comes into contact with the stored adhesive. Therefore, the bookbinding apparatus can reduce the diameter of the application roller for applying the adhesive.

Relative movement is possible in a posture located on the direction side, and the adhesive is applied to the end face of the sheet bundle and the first corner by rotating while relatively moving in the one direction, and relative movement in the other direction. By rotating while rotating, the sheet bundle end face, the lower end face (lower end face 8G) of the sheet bundle facing the upper end face, and the second corner (second part) that connects the sheet bundle end face are connected.

According to this configuration, the adhesive supplied to the peripheral surface by the supply means is likely to enter the inside of the recess. Therefore, the bookbinding apparatus can attach more adhesive to the peripheral surface of the application roller.

  (1-9) The moving means moves the application roller among the holding means and the application roller. According to this configuration, the application roller moves along the third direction while the holding means for holding the sheet bundle is stationary, and the adhesive is applied to the end of the sheet bundle. The bookbinding apparatus can save the space required for the holding means to move along the third direction. Therefore, the bookbinding apparatus can be reduced in size.

(1-10) The supply means includes a heat generating element (heater 347) capable of generating heat, and can supply a thermoplastic adhesive that dissolves when the heat generating element generates heat to the peripheral surface. According to this configuration, when the adhesive is applied to the end of the sheet bundle, the bookbinding apparatus dissolves and liquefies the adhesive by causing the heating element to generate heat. On the other hand, when the adhesive is not applied to the end portion of the sheet bundle, the bookbinding apparatus does not cause the heating element to generate heat, thereby causing the adhesive to transition to a solidified state where odor is hardly generated. Therefore, the bookbinding apparatus can suppress the generation of the odor of the adhesive.

(2) Effect of Second Disclosure Conventionally, there is known a bookbinding apparatus that performs wrapping and bookbinding by binding a sheet bundle with a cover and binding a booklet. The bookbinding apparatus includes an application device that forms an adhesive portion to which a cover can be attached by applying an adhesive to an end surface (hereinafter referred to as an adhesive surface) extending in the thickness direction of the sheet bundle. For example, a coating apparatus disclosed in Japanese Patent No. 4515116 includes a melt tank and a drum. The melt tank is formed in a substantially box shape whose upper side is open, and can store molten glue as an adhesive inside. The drum is rotatable around an axis extending in the horizontal direction while being immersed in the molten paste. The sheet bundle moves horizontally with the adhesive surface facing the rotating drum from above. As a result, the drum applies the molten paste stored in the melt tank to the bonding surface.

  In the above prior art, the diameter of the drum needs to be increased so that the drum can be immersed in the molten paste having a lowered liquid level. In view of such a problem, the second disclosure has the following configuration.

(2-1)

When the paper aligning means aligns the end face of the sheet bundle substantially flush, the storage tank is close to the end face of the sheet bundle from the second direction side, and the vertical direction and the first Moving means (conveyance motor 321) that moves along a third direction (left-right direction) orthogonal to the direction;
A part of the peripheral surface (peripheral surfaces 351A, 2351A, 3351A) is held by the storage tank at a position exposed to the second direction side from the opening, intersects the third direction, and the first An application roller (glue application roller 350, 2350, 3350) that is rotatable about an axis extending orthogonally to the direction, and extends along the axis and allows the adhesive to enter inside (groove 351C, 2351C) a plurality of the application rollers provided on the peripheral surface along the circumferential direction;
A bookbinding apparatus (bookbinding apparatus 1) comprising: a rotation means (drive motor 319) that rotates the application roller around the axis when the moving means moves the storage section.

  According to this configuration, when the moving unit moves the storage tank along the third direction, a part of the peripheral surface exposed from the opening is in the second direction on the sheet bundle end surface that is substantially flush. Move with storage tank in close proximity from the side. By rotating the application roller to which the rotating means moves, the groove part into which the adhesive has entered inside the storage part passes through the opening and rotates to the outside of the storage tank to apply the adhesive to the end face of the sheet bundle. To do. As a result, the adhesive is applied to the end face of the sheet bundle along the third direction. The application roller is arranged in a posture in which the axis intersects with the third direction and extends orthogonally to the first direction. For this reason, it is unlikely that the adhesive is gradually separated from the application roller as the adhesive stored in the storage tank decreases. Regardless of the amount of the adhesive stored in the storage section and the diameter of the peripheral surface, the application roller easily comes into contact with the stored adhesive. Therefore, the bookbinding apparatus can reduce the diameter of the application roller for applying the adhesive.

(2-2)
In the bookbinding apparatus, the application roller may substantially close the opening in the third direction. According to this configuration, the bookbinding apparatus can suppress leakage of the odor of the adhesive stored in the storage tank from the opening to the outside of the storage tank.

(2-3)
In the bookbinding apparatus, the storage tank may house at least half of the circumferential surface in the circumferential direction inside. According to this configuration, the bookbinding apparatus can reduce the circumferential surface exposed from the opening to less than half of the circumferential direction. Therefore, the bookbinding apparatus can suppress the generation of the odor of the adhesive.

(2-4)
In the bookbinding apparatus, the storage tank may include a supply path (glue supply path 341A) that can supply the adhesive to the storage unit, and a closing unit (lid member 348) that can close the supply port. Good. According to this configuration, when the adhesive is not supplied, the closing unit can close the supply path. Therefore, the bookbinding apparatus can further suppress leakage of the odor of the adhesive to the outside of the storage tank.

The bookbinding apparatus is provided in the storage tank, and is capable of moving together with the heating tank (heater 347) capable of heating the storage section by generating heat, and has entered the inside of the plurality of grooves. Among the adhesives, an adhesive receiving portion (glue receiving installation portion 313) capable of installing a first receiving member (glue receiving member 360) that receives the dropped adhesive below the application roller, and the storage And a support member (connecting plate 361) that is provided in the tank and has a heat insulating property to support the adhesive receiving portion, and the storage portion stores a thermoplastic adhesive that dissolves when the heating element generates heat. It may be possible. According to this configuration, the application roller applies the adhesive dissolved in the storage tank as the heating element generates heat to the end face of the sheet bundle. The adhesive dropped from the rotating application roller is collected by the first receiving member and solidified. Since the support member that connects the adhesive receiving portion and the storage tank has a heat insulating property, the heat generated by the heating element is difficult to propagate to the first receiving member installed in the adhesive receiving portion. Therefore, the liquid adhesive dropped on the first receiving member is likely to transition to a solidified state that hardly generates odor. Therefore, the bookbinding apparatus can further suppress the generation of the odor of the adhesive.

(2-6)
The bookbinding apparatus is a second receiving member (glue) that is provided in the storage tank and receives the dropped adhesive below the application roller among the adhesive that has entered the inside of the plurality of grooves. A receiving member 1360), and a delivery means (pump drive mechanism 1380) provided in the storage tank and collecting the adhesive falling on the second receiving member and sending it to the storage part. According to this configuration, the adhesive dropped on the second receiving member is delivered to the storage unit by the delivery means and stored again. Since the adhesive does not easily stay outside the storage tank, the bookbinding apparatus can further suppress the generation of the odor of the adhesive.

(2-7)
In the bookbinding apparatus, the storage tank may include a wall portion (front wall portion 349A) that surrounds the storage portion from the first direction side and that extends downwardly toward the application roller. Good. According to this structure, even if it is a case where the adhesive agent stored by the storage part reduces, an adhesive agent moves easily toward an application roller along a wall part. The application roller is more likely to come into contact with the stored adhesive regardless of the amount of adhesive stored in the storage unit. Therefore, the bookbinding apparatus can further reduce the diameter of the application roller for applying the adhesive.

(3) Effect of Third Disclosure Conventionally, a technique for applying an adhesive to an application target with an application roller is known. For example, in the apparatus disclosed in Japanese Patent Application Laid-Open No. 58-11061, the application roller to which glue as an adhesive is attached faces the upper surface of a framework such as furniture to be applied in the left-right direction. Rotate while moving along. At this time, the peripheral speed of the peripheral surface of the application roller is set to be substantially the same as the moving speed of the application roller. The application roller applies glue to the upper surface of the framework along the left-right direction. When the application roller applies glue to the end face of the sheet bundle, which is the end face extending in the thickness direction of the sheet bundle, the above apparatus is a bookbinding apparatus that wraps the sheet bundle with a cover and binds the booklet. Function.

  In the above prior art, since the rotation speed of the application roller is substantially the same as the movement speed, there is a possibility that sufficient glue cannot be applied to the end face of the sheet bundle depending on the movement speed of the application roller. In view of such a problem, the third disclosure has the following configuration.

Crossing a third direction (left-right direction) orthogonal to the first direction and the second direction, and rotatable about an axis extending perpendicular to the second direction, a plurality of extending along the axis Application rollers (glue application rollers 350, 2350, 3350) in which groove portions (groove portions 351C, 2351C) are provided on the peripheral surfaces (circumferential surfaces 351A, 2351A, 3351A) along the circumferential direction;
Supply means (main body 349) capable of supplying an adhesive to the plurality of grooves;
When the paper aligning means aligns the sheet bundle end surface substantially flush, the coating roller along the third direction with the peripheral surface approaching the sheet bundle end surface from the second direction side. Moving means (conveyance motor 321) for moving
A bookbinding apparatus comprising: a rotation unit (drive motor 319) capable of rotating the coating roller about the axis independently of movement by the moving unit and changing a rotation speed of the coating roller. (Bookbinding apparatus 1).

  According to this configuration, when the moving unit moves the application roller along the third direction with the peripheral surface approaching the sheet bundle end surface from the second direction side, the rotation unit rotates the application roller. Thus, the plurality of grooves apply the adhesive supplied by the supply unit to the end face of the sheet bundle. As a result, the adhesive is applied to the end face of the sheet bundle along the third direction. The rotating means can rotate the applying roller independently of the movement of the applying roller by the moving means, and the rotation speed of the applying roller can be varied. Therefore, the rotating means can rotate the application roller at an appropriate rotation speed in order to apply sufficient adhesive to the end face of the sheet bundle. Therefore, the bookbinding apparatus can apply a sufficient adhesive to the end face of the sheet bundle according to the moving speed of the application roller.

(3-2)
In the bookbinding apparatus, the first direction is a vertical direction, and the supply unit is formed in a box shape capable of storing the adhesive therein, and the application roller can be rotated around the axis in the inside. And a storage tank (main body portion 349) having an opening (roller installation portion 343) that exposes a part of the peripheral surface from the inside in a direction opposite to the second direction (rearward direction). The moving means may move the application roller together with the storage tank. According to this configuration, when the moving unit moves the storage tank along with the application roller along the third direction, the rotation unit rotates the application roller so that a part of the peripheral surface exposed from the opening is stored. The adhesive stored in the tank is applied to the end face of the sheet bundle. When the first direction is the vertical direction, the application roller is arranged in a posture that extends along the direction in which the axis intersects the horizontal direction. For this reason, it is unlikely that the adhesive is gradually separated from the application roller as the adhesive stored in the storage tank decreases. Regardless of the amount of the adhesive stored in the storage section and the diameter of the peripheral surface, the application roller easily comes into contact with the stored adhesive. Therefore, the bookbinding apparatus can reduce the diameter of the application roller for applying the adhesive.

(3-3)
In the bookbinding apparatus, the moving means reciprocates the application roller at least once along the third direction, and the rotation means is at least when the application roller moves in the forward path and when it moves in the return path. In one case, the application roller may be rotated. According to this configuration, when the rotating unit rotates the application roller, the adhesive is applied to the end face of the sheet bundle. Since the rotation means rotates the application roller when the application roller moves in the forward path and when the application roller moves in the return path, the bookbinding apparatus can determine the number and types of a plurality of sheets forming the sheet bundle. Thus, the amount of adhesive applied to the end face of the sheet bundle can be adjusted.

(3-4)
In the bookbinding apparatus, the rotation means rotates the application roller when the application roller moves in the forward path and the return path, and the movement means can change a moving speed of the application roller, The movement speed when moving the forward path to the application roller and the movement speed when moving the return path to the application roller may be different from each other. According to this configuration, the moving means can vary the time during which the adhesive is applied to the end face of the sheet bundle depending on whether the application roller moves in the forward path or in the return path. Therefore, the bookbinding apparatus can adjust the amount of adhesive applied to the end face of the sheet bundle depending on whether the application roller moves on the forward path or on the return path. Accordingly, the bookbinding apparatus can more flexibly adjust the amount of adhesive applied to the end face of the sheet bundle depending on the type and number of sheets of the sheet bundle.

(3-5)
In the bookbinding apparatus, the moving means reciprocates the application roller between one end (one end 8C) and the other end (other end 8D) which are ends in the third direction of the end face of the sheet bundle. Move
The rotating means rotates the peripheral surface at a peripheral speed substantially the same as the moving speed of the application roller when the application roller moves between the one end and the other end a first predetermined number of times (twice). When the application roller that has moved the first predetermined number of times moves between the one end and the other end a second predetermined number of times (twice), the peripheral speed is higher than the moving speed of the application roller. The surface may be rotated. According to this configuration, when the application roller moves for the first predetermined number of times, the movement speed of the application roller (hereinafter referred to as movement speed) and the peripheral speed of the peripheral surface (hereinafter referred to as peripheral speed) are substantially the same. Therefore, the frictional resistance generated between the adhesive immediately after being applied to the end face of the sheet bundle and the peripheral surface in contact with the adhesive is reduced. The adhesive tends to adhere to the end face of the sheet bundle. Therefore, the application roller can apply the adhesive evenly to the end face of the sheet bundle. Further, when the application roller moves the second predetermined number of times, the rotating means rotates the peripheral surface at a peripheral speed faster than the moving speed, so that the adhesive immediately after being applied to the end face of the sheet bundle is upstream in the rotation direction. It comes into contact with the circumferential surface that rotates from the side, and is biased toward the end face of the sheet bundle. As a result, the adhesive applied to the end face of the sheet bundle by the application roller moving the second predetermined number of times is directed in the direction opposite to the second direction together with the adhesive applied when the application roller moves the first predetermined number of times. It moves easily and easily enters between a plurality of sheets forming a sheet bundle. Accordingly, the bookbinding apparatus can apply the adhesive to the end face of the sheet bundle and simultaneously allow the adhesive to enter between a plurality of sheets forming the sheet bundle.

(3-6)
In the bookbinding apparatus, the moving means reciprocates the application roller between one end (one end 8C) and the other end (other end 8D) which are ends in the third direction of the end face of the sheet bundle. Move
The rotating means rotates the peripheral surface at a peripheral speed substantially the same as the moving speed of the application roller when the application roller moves between the one end and the other end a first number of times (twice). When the application roller that has moved the first number of times moves between the one end and the other end a second number of times (twice), the peripheral surface rotates at a peripheral speed faster than the moving speed of the application roller. When the application roller that has moved the second number of times moves between the one end portion and the other end portion a third number of times (twice), the peripheral surface has a circumferential speed that is substantially the same as the moving speed of the application roller. May be rotated. According to this configuration, when the application roller moves for the first number of times, the moving speed and the peripheral speed are substantially the same, so that the adhesive is evenly applied to the end face of the sheet bundle. When the applicator roller moves a second number of times, the peripheral speed is faster than the moving speed, so the applicator roller applies the adhesive to the end face of the paper bundle and, at the same time, enters the adhesive between the sheets forming the paper bundle. Can be made. Further, when the application roller moves a third number of times, since the moving speed and the peripheral speed are substantially the same, the adhesive is evenly applied to the end face of the sheet bundle. Therefore, the bookbinding apparatus can apply the adhesive evenly to the end face of the sheet bundle while simultaneously allowing the adhesive to enter between the plurality of sheets forming the sheet bundle.

(3-7)
The rotating means may rotate the peripheral surface at different peripheral speeds depending on whether the application roller moves on the forward path or moves on the return path. According to this configuration, the application roller can adjust the amount of the adhesive applied to the sheet bundle end surface when moving in the forward path and when moving in the return path. Therefore, the bookbinding apparatus can more flexibly adjust the amount of adhesive applied to the end face of the sheet bundle depending on the type and number of sheets of the sheet bundle.

(3-8)
The moving means reciprocates the application roller a plurality of times, and the rotating means moves the application roller along the forward path while the application roller reciprocates once. In the case of moving in the return path, the coating roller rotates in one reciprocation while the peripheral surface is rotated at substantially the same peripheral speed and the coating roller reciprocates twice continuously. The peripheral surface may be rotated at different peripheral speeds depending on the case and the other reciprocating movement. According to this configuration, the application roller reciprocates once under the condition that the moving speed and the peripheral speed are substantially the same, so that the adhesive is evenly and sufficiently applied to the end face of the sheet bundle. Furthermore, in two successive reciprocations, the peripheral surfaces rotate at different peripheral speeds. Therefore, the bookbinding apparatus can be adjusted to the extent that the amount of adhesive applied to the end face of the sheet bundle is not excessive, while applying sufficient adhesive to the end face of the sheet bundle.

(3-9)
Each of the first predetermined number of times and the second predetermined number of times may be twice. According to this configuration, when the application roller reciprocates for the first time, the moving speed and the peripheral speed are substantially the same, so the application roller can apply the adhesive evenly and sufficiently to the end face of the sheet bundle. Furthermore, when the application roller reciprocates for the second time, the peripheral surface rotates at a peripheral speed faster than the moving speed. Therefore, the adhesive applied by the application roller forms a paper bundle in the direction opposite to the second direction from the end face of the paper bundle together with the adhesive applied when the application roller is reciprocated for the first time. It is easy to enter between a plurality of sheets. Therefore, the bookbinding apparatus can apply a sufficient amount of adhesive between a plurality of sheets forming the sheet bundle at the same time as applying the adhesive to the end face of the sheet bundle.

(3-10)
Each of the first number of times, the second number of times, and the third number of times may be twice. According to this configuration, when the application roller reciprocates for the first time, the moving speed and the peripheral speed are substantially the same, so that the adhesive is evenly and sufficiently applied to the end face of the sheet bundle. When the applicator roller reciprocates for the second time, the peripheral speed is faster than the moving speed. Therefore, the applicator roller applies an adhesive to the end face of the paper bundle, and at the same time, it is sufficient between a plurality of sheets forming the paper bundle. Adhesive can enter. Further, when the application roller moves a third number of times, the moving speed and the peripheral speed are substantially the same, so that the adhesive is evenly and sufficiently applied to the end face of the sheet bundle. Therefore, the bookbinding apparatus allows a sufficient amount of adhesive to enter between a plurality of sheets forming the sheet bundle, and at the same time, evenly and sufficiently apply the adhesive to the end face of the sheet bundle.
