Technical Field

The present invention relates to a bonding apparatus.

Background

The cloth bonding apparatus described in japanese laid-open patent publication No. 2010-203028 has three switches. The cloth bonding apparatus assigns one of a plurality of functions (e.g., an adhesive stopping function) for controlling the operation of the cloth bonding apparatus to each switch. The operator operates the switch in order to input a control instruction of the operation during the bonding operation of the cloth bonding apparatus. The cloth bonding apparatus performs a function assigned to the switch in correspondence with the operation of the switch.

In some cases, an operator wants to change a plurality of functions at the same time while the cloth bonding apparatus is performing the bonding operation. The cloth bonding apparatus described above assigns a function to one switch. Therefore, the operator needs to operate a plurality of switches corresponding to the respective functions at the same time, which is troublesome.

The storage unit of the bonding apparatus stores a plurality of condition combinations, which are combinations of a plurality of control conditions. The bonding apparatus switches the condition combination in accordance with an upper sheet and a lower sheet (hereinafter collectively referred to as a sheet) to be bonded by an operation of an input portion, thereby collectively switching the control conditions included in the condition combination. Therefore, the bonding apparatus can easily switch a plurality of control conditions at the same time as compared with the conventional apparatus.

The bonding apparatus moves the end of the sheet in the orthogonal direction in accordance with the detection result of the lower detection unit or the upper detection unit. The control conditions include the respective detection sensitivities of the lower detection unit and the upper detection unit. Therefore, even when the material of the sheet or the like changes during the execution of the bonding operation, the bonding apparatus can be switched to the detection sensitivity of the lower detection section and the upper detection section suitable for the sheet, and the adhesive can be appropriately applied to the sheet.

The bonding apparatus according to claim 5 may further include a start/stop instruction unit configured to input an instruction to start or stop the bonding operation, wherein the control condition includes a start/stop combination that is a combination of controls of the plurality of operation units that operate in accordance with the instruction from the start/stop instruction unit, and the start/stop combination includes a combination of times at which the operation control unit starts or stops the operations of the supply mechanism and the transport mechanism. The bonding apparatus can resume bonding to a sheet under control conditions suitable for the sheet when the bonding operation is resumed after the bonding operation is interrupted.

The stop start time combination of the bonding apparatus according to claim 6 may include a combination of whether or not the conveyance mechanism is operated to convey the lower sheet and the upper sheet in the reverse direction of the conveyance direction and a distance to convey the lower sheet and the upper sheet in the reverse direction when the operation control unit stops the bonding operation. The bonding apparatus can resume bonding to a sheet under control conditions suitable for the sheet when the bonding operation is resumed after the bonding operation is interrupted. Therefore, the bonding apparatus can suppress uneven adhesion of the adhesive to the sheet due to the interruption of the bonding operation.

The bonding apparatus according to claim 7 may further include a holding mechanism including: a holding member that switches between a holding state in which the holding member holds a conveyed sheet on an upstream side in the conveying direction from the nozzle, the conveyed sheet being one of the upper sheet and the lower sheet to which the adhesive is to be adhered, and a released state in which the holding member releases the holding of the conveyed sheet; and a holding drive unit that moves the holding member, wherein the operation unit includes the holding mechanism, the operation control unit controls the holding drive unit to switch the holding member to the released state when the bonding operation is started, and to switch the holding member to the held state when the bonding operation is stopped, and the start-stop combination includes a combination of whether or not the operation control unit switches the holding member to the released state or the held state and a time when the switching of the holding member is started.

The bonding device enlarges the interval between the nozzle and the lower sheet when the bonding operation is interrupted, and reduces the interval when the bonding operation is restarted. The bonding apparatus can suppress the degree of penetration into the sheet from changing due to the heat of the adhesive adhering to the sheet. The start/stop combination includes the size of the gap and the control of the expansion or contraction of the gap when starting or stopping the bonding operation. Therefore, the bonding apparatus can suppress uneven adhesion of the adhesive to the sheet due to the interruption of the bonding operation.

When the sheet has a stepped portion, the bonding apparatus detects a change in thickness of the lower sheet by the sheet thickness detection portion and changes the interval according to the thickness of the stepped portion. Therefore, when the lower sheet has the stepped portion, the bonding apparatus can still suppress the adhesive from being unevenly adhered to the sheet.

The supply mechanism of the bonding apparatus according to claim 11 may include a supply drive unit configured to supply the adhesive to the nozzle by driving of the supply drive unit, wherein the operation control unit may control the supply drive unit so that a thickness of the adhesive discharged from the nozzle becomes a predetermined thickness, and the control condition may include the thickness of the adhesive.

The control conditions of the bonding apparatus include a pressing force when the upper conveying portion presses the sheet between the upper conveying portion and the lower conveying portion. Therefore, the bonding apparatus can convey the sheet with a pressing force appropriate for the job of bonding the sheet.

The input unit of the bonding apparatus according to claim 13 may be a switch that can be operated by an operator, and the bonding apparatus may include a setting unit that sets a start-time combination and an operation-time combination, respectively, and stores them in the storage unit, the start-time combination being the condition combination of the control conditions that is controlled by the operation control unit when the bonding operation is started, and the operation-time combination being the condition combination of the control conditions that is controlled by the operation control unit when the operator operates the switch during execution of the bonding operation.

The lower conveyance mechanism 50 includes a housing 55, a lower conveyance drive unit 60, and the like. The frame 55 extends in the front-rear direction and the left-right direction, and is open upward in a box shape. The frame 55 houses the lower conveyance drive unit 60. A support plate 57 extending in the horizontal direction is provided at the upper end of the frame 55. The upper opening of the frame 55 is closed by a support plate 57. The lower sheet 8 and the upper sheet 6 are supported by the support plate 57. The rear end of the frame 55 is an opening 553 which opens rearward. The opening 553 is inclined from the front upper side to the rear lower side. The rear end of the lower conveyance driver 60 protrudes rearward from the opening 553.

A fixed shaft portion 316 projecting upward is provided at the rear end right portion of the support plate 57. The rotation support portion 314 is supported by the fixed shaft portion 316. The rotation support portion 314 is a plate member having a substantially rectangular shape in plan view. The rotation support portion 314 is rotatable about the fixed shaft portion 316 between an operating position (see fig. 3) and a retracted position. The pivot support portion 314 in the operating position is located directly below the upper pinch roller 32 described below and directly above the lower pinch roller 76 described below (see fig. 4). The retracted position is a position where the rotation support portion 314 is rotated by about 90 ° in the counterclockwise direction in the plan view from the operating position. The rotational bearing 314 has an upper surface 315 and a lower surface 317. A lower reflective plate is provided on the lower surface 317.

As shown in fig. 5 and 6, the lower conveyance drive unit 60 includes a support frame 61, a lower conveyance motor 63, a lower conveyance roller 64, a lower nozzle roller 65, a conveyance belt 67 (see fig. 9), and the like. The support frame 61 extends in the front-rear direction, is open upward, and has a substantially U-letter shape. A nozzle plate 59 and a tip plate 56 are fixed to the upper rear end of the support frame 61. The nozzle plate 59 extends in the front-rear direction. The top end plate 56 extends downward rearward from the rear end of the nozzle plate 59. The nozzle plate 59 has an opening 591 opened in the vertical direction. The opening 591 is located directly below the rotation support portion 314 when in the operating position. A roller opening 592 is provided at a connecting portion between the nozzle plate 59 and the tip end plate 56. The roller opening portions 592 penetrate the nozzle plate 59 and the tip end plate 56 in the thickness direction, respectively.

The lower conveying motor 63 is a motor capable of rotating in forward and reverse directions, and is fixed to the front right surface of the supporting frame 61. The drive shaft of the lower conveyance motor 63 protrudes leftward from the right portion of the support frame 61. The lower feed roller 64 is fixed to a rotating shaft 641, and the rotating shaft 641 is rotatably supported by the rear end portion of the support frame 61. The upper end of the lower conveying roller 64 protrudes outward from the roller opening 592. The lower conveying roller 64 supports the lower sheet 8 and the upper sheet 6 overlapped with the adhesive Z sandwiched therebetween. The nozzle lower roller 65 is fixed to the rotating shaft 651. The support frame 61 supports the rotating shaft 651 so that the rotating shaft 651 can rotate in front of the rotating shaft 641. The upper end portion of the lower nozzle roller 65 protrudes upward from the opening portion 591. The conveyor 67 is mounted on the drive shaft of the lower conveyor motor 63, the rotating shaft 641, and the rotating shaft 651 inside the support frame 61. The conveying belt 67 transmits the driving force of the lower conveying motor 63 to the lower conveying roller 64 and the nozzle lower roller 65. Therefore, when the lower conveyance motor 63 is driven, the lower conveyance roller 64 and the nozzle lower roller 65 rotate about the horizontal direction as the axial direction.

Referring to fig. 5, the gap adjusting section 77 housed in the housing 55 will be described. The gap adjusting portion 77 can change the distance between the nozzle 11 and the lower sheet 8 (hereinafter referred to as a nozzle gap) described later by changing the vertical position of the lower conveying mechanism 50. The gap adjusting part 77 has the gap adjusting motor 68, the cam plate 69, the swing shaft 62, and a spring. The gap adjustment motor 68 is provided above the fixing plate 512 (see fig. 1) and below the lower conveyance motor 63. The fixed plate 512 extends leftward from the lower end of the support plate 51. A drive shaft 681 of the gap adjustment motor 68 protrudes leftward, and a cam plate 69 having a substantially circular shape in a left view is fixed to the drive shaft 681. The cam plate 69 is located inside a cam hole 631 provided in a lower right portion of the support frame 61, and the center of the cam plate 69 is eccentric with respect to a drive shaft 681 of the gap adjustment motor 68.

The swing shaft 62 extends in the left-right direction and is fixed to the housing 55 (see fig. 3). The swing shaft 62 rotatably supports a substantially central portion of the support frame 61 in the front-rear direction of the support frame 61. The spring biases the support frame 61 in a direction to swing the rear end portion of the support frame 61 downward. Therefore, the cam plate 69 is in contact with the lower end portion of the cam hole 631. When the cam plate 69 is rotated by the driving of the gap adjustment motor 68, the support frame 61 swings about the swing shaft 62 in accordance with the rotation angle of the cam plate 69. The rear end of the support frame 61 is moved up and down (arrow Q) by the gap adjustment motor 68 to change the nozzle gap. The lower transport roller 64 and the lower nozzle roller 65 oscillate in the vertical direction as the nozzle gap is changed. In fig. 4, the lower transport roller 64 and the lower nozzle roller 65 when the rear end of the support frame 61 is located upward are illustrated by solid lines, and the lower transport roller 64 and the lower nozzle roller 65 when the rear end of the support frame 61 is located downward are illustrated by two-dot chain lines.

Referring to fig. 5 and 8, the lower clamping mechanism 80 is illustrated. The lower clamp mechanism 80 is housed in the housing 55 (see fig. 3). The lower clamp mechanism 80 can clamp the lower sheet 8 between the lower surface 317 (see fig. 4) of the turn support 314 and can change the position of the lower sheet 8 in the left-right direction. The lower clamp mechanism 80 includes a fixing seat 71, a lower clamp motor 72, a connecting shaft 910, a support frame 73, a transmission belt 74, a shaft portion 75, a lower clamp roller 76, a moving mechanism 81, and the like. The fixing seat portion 71 is substantially rectangular parallelepiped and fixed to the front inner side of the frame 55. The fixing seat portion 71 has a through hole 711 formed in a circular shape in the front-rear direction, and the rotating portion 717 is rotatably held inside the through hole 711. The rotation center of the rotating portion 717 is an axis J extending in the front-rear direction.

The lower clamp motor 72 is a motor capable of rotating in forward and reverse directions, and is fixed to a front surface of the rotating portion 717. The lower clamp motor 72 rotates together with the rotating portion 717 with respect to the stationary seat portion 71. A pin 940 protruding upward is provided on the rear portion of the upper surface of the lower clamp motor 72. An upper end portion of the spring 946 is fixed to a rear portion of the left surface of the lower clamp motor 72. The lower end of the spring 946 is fixed to the inside of the frame 55.

The drive shaft of the lower clamp motor 72 is inserted into a through hole provided in the center of the rotating portion 717 and is connected to the connecting shaft 910. The coupling shaft 910 protrudes rearward from the rear surface of the rotating portion 717. The support frame 73 is located behind the fixing seat 71 and is fixed to the rear surface of the rotating portion 717. Therefore, the support frame 73 rotates together with the rotating portion 717. The spring 946 always urges the lower clamp motor 72 counterclockwise in the front view. The rear end of the coupling shaft 910 is accommodated inside the support frame 73. The support frame 73 rotatably supports the tip end of the shaft 75 by the shaft 75. The belt 74 is mounted on the coupling shaft 910 and the shaft 75. The shaft portion 75 extends in the front-rear direction at a position on the upper right with respect to the axis J.

The lower pinch roller 76 is fixed to a rear end portion of the shaft portion 75 and is located between the nozzle plate 59 and the support plate 57 (see fig. 3). The lower pinch roller 76 can pinch the lower sheet 8 between it and a lower surface 317 (refer to fig. 4) of the rotary support 314 in the working position. When the lower clamp motor 72 is driven, the shaft 75 is rotated via the drive shaft of the lower clamp motor 72, the coupling shaft 910, and the transmission belt 74. Therefore, the lower pinch roller 76 rotates about the longitudinal direction as the axial direction, and the position of the lower sheet 8 in the lateral direction can be changed.

The moving mechanism 81 has a plate portion 930, a cylinder 931, and a plate member 933. The plate 930 is provided on the upper surface of the fixing seat 71 and extends in the left-right direction. Cylinder 931 is provided in the left portion of plate portion 930. An output rod 932 of the cylinder 931 extends rightward. The plate member 933 has an L-shape in front view, and is fixed to the right end of the output rod 932. The right end of the plate member 933 abuts against the pin 940 of the lower clamp motor 72.

When the output rod 932 advances rightward, the plate member 933 moves the pin 940 rightward. As the pin 940 moves, the lower clamp motor 72 swings around the axis J in the clockwise direction in the front view (arrow a and arrow B) together with the support frame 73 against the biasing force of the spring 946. The shaft 75 moves downward, and the lower pinch roller 76 swings about the axis J to a downward spaced position (arrow C). The lower separated position is a position to which the lower nip roller 76 swings after the upper end of the lower nip roller 76 is separated downward from the lower surface 317. In fig. 4, the lower pinch roller 76 is illustrated in a two-dot chain line at the lower separated position.

When the cylinder 931 is driven and the output rod 932 moves leftward and separates from the shaft 940, the lower clamp motor 72 swings together with the support frame 73 in the counterclockwise direction in the front view about the axis J by the urging force of the spring 946. The lower nip roller 76 swings to the lower nip position centering on the axis J. The lower nip position is a position to which the lower nip roller 76 swings when nipping the lower sheet 8 between it and the lower surface 317. In fig. 4, the lower nip roller 76 is illustrated in a solid line at the lower nip position.

Referring to fig. 5 and 8, the position detection unit 950 housed in the housing 55 will be described. The position detection part 950 has an extension setting member 951, a magnet, and a magnetic sensor 963. The extension member 951 extends downward from the rear lower end of the lower clamp motor 72 and rotates together with the lower clamp motor 72. The magnet is a permanent magnet fixed to a lower end portion of the extension member 951, and moves in the left-right direction in accordance with the rotation of the extension member 951. The magnetic sensor 963 is fixed to the support plate 998. The support plate 998 extends downward from the front surface of the fixed seat portion 71 in front of the magnet. The magnetic sensor 963 can detect the magnetic field of the magnet. The vertical position of the lower pinch roller 76 changes according to the thickness change of the lower sheet 8. At this time, the position of the magnet in the left-right direction changes, and the magnetic field detected by the magnetic sensor 963 changes. Therefore, the position detector 950 can detect the amount of vertical movement and the direction of movement of the lower pinch roller 76 based on the detection result of the magnetic sensor 963, and can detect a change in the thickness of the lower sheet 8.

Referring to fig. 4, the lower detection unit 78 will be described. The lower detection portion 78 is located inside the support frame 61 and below an opening portion 591 (see fig. 6) of the nozzle plate 59. The lower detection unit 78 is an optical detector in which a light emitting unit and a light receiving unit are integrated. The light emitting section and the light receiving section are at the same height position with each other. The light emitting portion emits light toward the opening 591 of the nozzle plate 59. The light passing through the opening 591 is reflected downward by the lower reflection plate of the rotation support portion 314 when in the operating position. The reflected light reflected by the lower reflection plate passes through the opening 591. The light receiving unit can receive the reflected light transmitted through the opening 591.

When the lower specific end portion 8A of the lower sheet 8 is located above the opening portion 591, the lower specific end portion 8A blocks light emitted by the light emitting portion. When the lower specific end portion 8A is not located above the opening 591, light emitted from the light-emitting portion is reflected by the lower reflection plate, and the light-receiving portion receives the reflected light through the opening 591. The lower detection unit 78 can detect whether or not the lower specific end portion 8A is at the lower detection position based on the magnitude relationship between the light amount received by the light receiving unit and the lower detection threshold as the light amount threshold. The lower detection position is on the right side of the position when the lower sheet 8 is nipped between the lower pinch roller 76 and the lower surface 317, and is on the front side of the nozzle 11 described later.

As shown in fig. 2, the upper transport mechanism 70 includes an upper transport arm 16, an upper transport roller 12, an upper transport motor 112, and an air cylinder 122 (see fig. 12). The upper transport arm 16 extends forward from the rear below the head unit 5, and then extends forward and downward. The upper transport roller 12 is fixed to a rotation shaft extending in the left-right direction, and the rotation shaft is rotatably supported by a distal end portion 16A of the upper transport arm 16. The upper transport motor 112 is a motor that is provided in the upper transport arm 16 and is rotatable in the forward direction and the reverse direction, and the upper transport motor 112 is connected to the upper transport roller 12 via a transmission mechanism provided inside the upper transport arm 16. The transmission mechanism is, for example, a pulley or a belt. The upper feed roller 12 is rotated about the axis in the left-right direction by the power of the upper feed motor 112.

The cylinder 122 is provided in the nose portion 5 in a posture along the front-rear direction, and is connected to the upper transport arm 16 via a link mechanism. The upper transfer arm 16 is driven by the air cylinder 122 to swing in the up-down direction. The air cylinder 122 swings the upper transport arm 16, and the upper transport roller 12 swings between the nip position (see fig. 4) and the upper position (see fig. 2). The nip position is a position to which the upper conveying rollers 12 swing when nipping the lower sheet 8 and the upper sheet 6 between them and the lower conveying rollers 64. The position where the upper conveying rollers 12 and the lower conveying rollers 64 nip the lower sheet 8 and the upper sheet 6 corresponds to a point P in fig. 4. The upper position is a position to which the upper conveying roller 12 swings after being separated upward from the nip position.

Referring to fig. 7, the upper clamp mechanism 30 is explained. The upper clamp mechanism 30 can change the position of the upper sheet 6 in the left-right direction. The upper clamp mechanism 30 is provided below the arm portion 4. The upper clamp mechanism 30 has a support portion 34, an upper arm 31, a rotation shaft 33, an upper clamp roller 32, an upper clamp motor 38, a transmission mechanism, a spring 37, an air cylinder 39, and the like. The support portion 34 is fixed to the right side portion of the lower surface of the arm portion 4, and has a through hole having a circular shape opened in the front-rear direction. The upper rotary portion is rotatably supported at the through hole, and the upper rotary portion protrudes forward and rearward from the through hole of the support portion 34. The rotation axis of the upper rotating portion is an axis W extending in the front-rear direction. The upper arm 31 extends downward to the left from the upper turning portion, and has a distal end portion 31A at a lower left end portion of the upper arm 31. The upper arm 31 swings with the rotation of the upper rotating portion.

The distal end portion 31A of the upper arm 31 rotatably supports a rotating shaft 33 extending in the front-rear direction. The upper pinch roller 32 is fixed to a rotating shaft 33. The upper pinch roller 32 is rotatable about the longitudinal direction as the axial direction, and the upper pinch roller 32 is located above the lower pinch roller 76 and on the front side of the upper transport roller 12. The upper clamp motor 38 is a motor fixed to the rear portion of the upper rotating portion and capable of rotating in the forward and reverse directions, and is capable of rotating together with the upper rotating portion. The drive shaft of the upper clamp motor 38 projects forward and enters the interior of the upper rotating portion. The transmission mechanism includes a shaft member extending in the front-rear direction inside the upper rotating portion, and a pulley, a belt, and the like provided at a front end of the shaft member. The transmission mechanism transmits the driving force of the upper nip motor 38 to the upper nip roller 32, and the upper nip roller 32 rotates about the longitudinal direction as the axial direction, so that the position of the upper sheet 6 in the lateral direction can be changed.

The upper arm 31 swings about the axis W as the upper swing portion rotates. The upper nip roller 32 swings between an upper nip position (see fig. 4) and an upper spaced position (see fig. 7). The upper nip position is a position to which the upper nip roller 32 swings when the upper nip roller 32 nips the upper sheet 6 between the lower end thereof and the upper surface 315 of the rotary support 314. The upper separation position is a position to which the upper nip roller 32 swings after separating upward from the upper nip position.

The spring 37 biases the upper arm 31 in the clockwise direction in the front view about the axis W via another member. Therefore, the spring 37 biases the upper arm 31 in a direction of rotating from the upper clamping position toward the upper release position. The tip end 31A of the upper arm 31 is moved downward by the own weight of the upper arm 31, the upper pinch roller 32, and the like. Since the spring 37 biases the upper arm 31 in the direction opposite to the biasing force, it is possible to suppress the upward force of the upper nip roller 32 when the upper nip position is set from becoming excessively large. The cylinder 39 is fixed to the support portion 34. The cylinder 39 rotates the upper clamp motor 38 about the axis W by the fixing member 35 fixed to the right surface of the upper clamp motor 38. Therefore, the upper grip roller 32 swings from the upper grip position to the upper spaced position by the driving of the air cylinder 39.

The upper detection unit 85 provided in the arm unit 4 will be described. The upper detection unit 85 is an optical detector in which a light emitting unit and a light receiving unit are integrated. The upper detection portion 85 is located between the upper conveyance roller 12 and the upper pinch roller 32 in the front-rear direction. The light emitting section and the light receiving section are at the same height position with each other. The light emitting section emits light from above toward an upper reflecting plate provided in a nozzle 11 described later. The light emitted from the light emitting part can be reflected by the upper reflection plate. The light receiving unit can receive the reflected light reflected by the upper reflecting plate.

When the upper specific end portion 6A of the upper sheet 6 is positioned above the upper reflection plate, the upper specific end portion 6A blocks the light emitted from the light emitting portion. When the upper specific end portion 6A is not located above the upper reflection plate, the light emitted from the light emitting portion is reflected by the upper reflection plate, and the light receiving portion receives the reflected light. The upper detection unit 85 can detect whether or not the upper specific end portion 6A is at the upper detection position based on the magnitude relationship between the light amount received by the light receiving unit and the upper detection threshold as the light amount threshold. The upper detection position is on the left side of the position when the upper sheet 6 is sandwiched between it and the upper surface 315 by the upper nip roller 32, and is above the nozzle 11.

The nozzle swing mechanism 22 provided in the head unit 5 will be described. The nozzle swing mechanism 22 has a nozzle motor 113, a support shaft 9, a nozzle lever 18, and the like. The nozzle motor 113 is fixed inside the head unit 5. A drive shaft of the nozzle motor 113 extends forward, and a motor gear 15 is fixed to the drive shaft. The support shaft 9 extends in the left-right direction above the drive shaft of the nozzle motor 113. A worm wheel 25 that meshes with the upper portion of the motor gear 15 is fixed to the center portion of the support shaft 9. The nozzle lever 18 is fixed to the left end of the support shaft 9 and extends downward from the support shaft 9. The nozzle 11 is connected to the lower end of the nozzle bar 18, and the nozzle 11 is positioned in front of the lower transport roller 64 and the upper transport roller 12. The nozzle 11 has a vertically extending portion extending downward from the nozzle bar 18 and a horizontally extending portion extending rightward from a lower end of the vertically extending portion. The horizontally extending portion has a liquid discharge port 13 on the lower surface. The liquid discharge port 13 is a plurality of circular holes arranged at substantially equal intervals in the left-right direction. The upper sheet 6 is located above the horizontally extending section. Therefore, the nozzle 11 can discharge the adhesive Z between the lower sheet 8 and the upper sheet 6 from the liquid discharge port 13.

The driving force of the nozzle motor 113 is transmitted to the motor gear 15 and the worm wheel 25, the nozzle lever 18 rotates about the support shaft 9, and the nozzle 11 moves between the close position (see fig. 2) and the retracted position. When the nozzle 11 is in the close position, the liquid discharge port 13 is positioned directly above the lower nozzle roller 65 and faces downward. The nozzle 11 in the retracted position is on the front side of the upper pinch roller 32. When the nozzle 11 is in the retracted position, the discharge port 13 faces forward and downward.

The nozzle rod 18 and the nozzle 11 have liquid flow paths of the adhesive Z communicating with each other inside thereof. The liquid flow path of the nozzle 11 communicates with the liquid discharge port 13. The nozzle bar 18 has a heater 132 (see fig. 12) therein. The heater 132 heats the adhesive Z in the nozzle bar 18.

The nozzle 11 also has an air flow path inside. The air flow path communicates with the air discharge port of the nozzle 11 and the outlet port of the air discharge mechanism. The air discharge port is provided on the lower surface of the horizontally extending portion of the nozzle 11. The air outlet is a plurality of circular holes arranged at substantially equal intervals in the left-right direction. The air discharge port is arranged in front of the liquid discharge port 13 with a predetermined interval from the liquid discharge port 13. When the nozzle 11 is in the close position, the air discharge port is directed downward. The air discharge port can discharge the air supplied by the air discharge mechanism.

The air discharge mechanism includes an inlet, an outlet, an internal flow path, an electromagnetic valve 401 (see fig. 12), and a heater 411 (see fig. 12). The inlet of the air discharge mechanism is connected with an air compressor. The air compressor sends air to the inflow port. The inner flow path communicates with the inlet and the outlet. The solenoid valve 401 is provided in the internal flow path. When the electromagnetic valve 401 is closed, the flow of air in the internal flow path is stopped. When the electromagnetic valve 401 is opened, air flows in the internal flow path. At this time, the air discharge mechanism supplies the air sent from the air compressor from the outflow port to the air discharge port of the nozzle 11. The nozzle 11 in the close position discharges air toward the lower sheet 8. The heater 411 generates heat, and can heat air flowing through the internal flow path.

Referring to fig. 1, a fitting portion 41 provided in the head portion 5 is explained. The inner container is assembled to the assembly portion 41. The inner container contains a hot-melt adhesive Z. The adhesive Z becomes liquid when heated to a predetermined temperature, and becomes solid at a temperature lower than the predetermined temperature. The adhesive Z is melted by heating with a heater 131 (see fig. 12) provided inside the mounting portion 41 and becomes liquid.

Referring to fig. 7, the supply mechanism 45 will be described. The supply mechanism 45 includes a pump motor 114, a gear pump 46, a nozzle valve 181 (see fig. 12), and a cylinder 182 (see fig. 12). The pump motor 114 is provided inside the arm portion 4 on the right front side of the fitting portion 41. The drive shaft of the pump motor 114 extends leftward and is connected to the gear pump 46 via gears. The gear pump 46 is coupled to the support shaft 9. The gear pump 46 sucks the adhesive Z from the inner container by driving of the pump motor 114, and supplies the sucked adhesive Z to the liquid flow path of the nozzle lever 18. The cylinder 182 is provided inside the nozzle rod 18. The actuating rod of the cylinder 182 is connected to the nozzle valve 181. The nozzle valve 181 is provided in the liquid flow path of the nozzle lever 18, and opens and closes the liquid flow path by driving of the air cylinder 182. When the nozzle valve 181 opens the liquid flow path, the adhesive Z flows through the liquid flow path to the liquid flow path of the nozzle 11. Therefore, the nozzle 11 discharges the adhesive Z from the liquid discharge port 13. When the nozzle valve 181 closes the liquid flow path, the flow of the adhesive Z in the liquid flow path is stopped.

The holding mechanism 800 is explained with reference to fig. 4 and fig. 9 to 11. The holding mechanism 800 has a bearing seat 802, a rotating shaft 804, a rotating member 806, a cylinder 809, and a holding member 810. The support base 802 extends upward from the inner bottom of the frame 55 and enters the support frame 61. A rotation shaft 804 extending in the left-right direction is supported by the upper end of the support base 802. The rotating members 806 are provided rotatably at both left and right ends of the rotating shaft 804. The rotating member 806 has: a first arm 806A extending downward from a portion connected to the rotating shaft 804; and a second arm 806B extending rearward from a portion connected to the rotating shaft 804. The second arm 806B is on the lower side of the shaft portion 75 of the lower clamp mechanism 80. The cylinder 809 is fixed to the front of the first arm 806A and inside the frame 55. The air cylinder 809 has a driving rod 809A extending in the front-rear direction. The rear end of the drive rod 809A is connected to the lower end of the first arm 806A.

The holding member 810 is fixed to the rear end of the second arm 806B, and is located below the rotation support 314. The holding member 810 has a substantially U-shape that opens downward. The open portion of the holding member 810 is a through hole 810A through which the shaft portion 75 is inserted. When the lower nip roller 76 of the lower nip mechanism 80 swings between the lower nip position and the lower spaced position, the shaft 75 swings vertically inside the through hole 810A.

The drive rod 809A is moved in the front-rear direction by the drive of the air cylinder 809, the rotation member 806 rotates with respect to the rotation shaft 804, and the holding member 810 is switched between a holding state (see fig. 10) and a release state (see fig. 11). The holding member 810 in the held state projects upward from the notch portion 57A (see fig. 3) at the rear end of the support plate 57, and holds the lower sheet 8 by sandwiching the lower sheet 8 between the lower surface 317 and the holding member. The upper end of the holding member 810 in the released state is positioned substantially at the same vertical position as the upper surface of the support plate 57, and the lower sheet 8 between the upper end and the lower surface 317 is released. Hereinafter, the holding mechanism 800 in the holding state of the holding member 810 is referred to as the holding mechanism 800 in the holding state, and the holding mechanism 800 in the released state of the holding member 810 is referred to as the holding mechanism 800 in the released state.

Referring to fig. 12, an electrical structure of the bonding apparatus 1 will be described. The bonding apparatus 1 has a control device 90. The control device 90 includes a CPU91, a ROM92, a RAM93, a storage device 94, a potentiometer 95, and drive circuits 96 to 98. The CPU91 comprehensively controls the operation of the bonding apparatus 1. The CPU91 is connected to the ROM92, the RAM93, the storage device 94, the switch 17, the operation unit 19, the potentiometer 95, the lower detection unit 78, the upper detection unit 85, the drive circuits 96 to 98, the heater 131, the heater 132, the heater 411, the magnetic sensor 963, and the display unit 260. The ROM92 stores programs that execute various processes. The RAM93 temporarily stores various information. The storage device 94 stores various parameters necessary when the CPU91 executes various programs, a condition combination table 87 described later, and a start/stop time combination table 88 described later.

The switch 17 is provided at a lower portion of the table, and is operated by the operator using the knees. The switch 17 detects an operation by the operator, and outputs the detection result to the CPU 91. The operation unit 19 detects input of various information and outputs the detection result to the CPU 91. The potentiometer 95 is connected to the pedal 7. The pedal 7 is provided below the switch 17 at a lower portion of the table, and the operator can rotate the pedal 7 between the stepped-in position and the stepped-back position by foot operation. The step-in position is a position of the pedal 7 when the operator steps in the pedal 7. The step-back position is a position of the pedal 7 when the operator steps back the pedal 7. There is a neutral position between the stepped-in position and the stepped-back position. The position of the pedal 7 is detected by the potentiometer 95. The potentiometer 95 outputs a start instruction, which will be described later, to the CPU91 when the pedal 7 is in the depressed position, outputs a stop instruction, which will be described later, to the CPU91 when the pedal 7 is in the neutral position, and outputs an end instruction, which will be described later, to the CPU91 when the pedal 7 is in the depressed position. The lower detection unit 78 and the upper detection unit 85 output the detection results to the CPU 91.

The CPU91 sends control signals to the drive circuit 96 to control the driving of the lower conveyance motor 63, the upper conveyance motor 112, the nozzle motor 113, the pump motor 114, the gap adjustment motor 68, the lower grip motor 72, and the upper grip motor 38, respectively. The CPU91 sends control signals to the drive circuit 97 to control the driving of the air cylinder 39, the air cylinder 122, the air cylinder 182, the air cylinder 809, and the air cylinder 931. The CPU91 sends a control signal to the drive circuit 98 to open and close the solenoid valve 401, thereby controlling the discharge of air from the air discharge port of the nozzle 11.

The CPU91 drives the heater 131, the heater 132, and the heater 411. The heater 131 heats the adhesive Z in the inner container, and the heater 132 heats the adhesive Z in the liquid flow path inside the nozzle lever 18. The adhesive Z becomes liquid by being heated by the

heaters

131 and 132. The heater 411 heats air in the internal flow path of the air discharge mechanism. The air discharged from the air discharge port of the nozzle 11 becomes a high temperature by being heated by the heater 411. The CPU91 detects a change in the thickness of the lower sheet 8 based on the detection result of the magnetic sensor 963. The display unit 260 is provided on the table, and displays various information in response to a control signal from the CPU 91.

Referring to fig. 13, the condition combination table 87 stored in the storage device 94 will be described. The condition combination table 87 has a plurality of storage areas storing a plurality of condition combination numbers and condition combinations corresponding to the condition combination numbers. Hereinafter, a condition combination having a condition combination number of X is referred to as an X-th condition combination. The bonding apparatus 1 performs the following bonding operation: the lower sheet 8 and the upper sheet 6 are bonded while being conveyed rearward with the adhesive Z discharged from the nozzle 11 in between. The combination of conditions is a combination of control conditions that the CPU91 controls each mechanism that operates during execution of the bonding operation.

The control conditions of the condition combination include a lower conveyance roller speed, an upper conveyance roller speed, a lower detection threshold, an upper detection threshold, a start/stop time combination, a film thickness, a nozzle gap interval, a step portion setting, and a pressing force. The lower conveying roller speed is a speed at which the lower conveying roller 64 rotates. The upper feed roller speed is the speed at which the upper feed roller 12 rotates. The description of the start/stop time combination will be described later. The film thickness is the thickness of the adhesive Z applied to the lower sheet 8 in the vertical direction. The film thickness is determined by the lower transport roller speed and the speed at which the pump motor 114 is driven. The nozzle gap spacing is the size of the nozzle gap. The step setting can be set to either one of the valid and invalid. When the step portion is set to be effective, the CPU91 controls the gap adjustment motor 68 based on the detection result of the position detection portion 950, and when the lower sheet 8 has the step portion, the nozzle gap interval can still be automatically and appropriately adjusted. The pressing force is a force applied to the lower conveying roller 64 by the upper conveying roller 12 in the nip position. The magnitude of the pressing force is determined by the thrust of the cylinder 122.

Referring to fig. 14, the start/stop combination table 88 stored in the storage device 94 will be described. The start/stop time combination table 88 stores a plurality of start/stop time combinations. The start/stop combination is a combination of controls for the respective mechanisms when the bonding apparatus 1 starts or stops the bonding operation. When the bonding apparatus 1 starts or stops the bonding operation, the CPU91 controls each mechanism according to the control conditions of each mechanism corresponding to the start/stop combination.

The start/stop time combinations include first to eighth times, inversion setting, inversion distance, hold setting, expand interval, blow setting, and blow temperature. The first time is a time from the instruction to start the bonding operation to the start of driving of the conveyance mechanism 20. The second time is a time from the instruction to stop the bonding operation to the time when the driving of the conveyance mechanism 20 is stopped. Hereinafter, the instruction to start the bonding operation is referred to as a start instruction, and the instruction to stop the bonding operation is referred to as a stop instruction.

The flip setting can be set to either one of active and inactive. When the reverse setting is enabled, the CPU91 controls the conveyance mechanism 20 to convey the sheet 200 forward by a predetermined distance after stopping the conveyance of the sheet 200 backward in accordance with the stop instruction. The forward conveyance of the sheet 200 is hereinafter referred to as reverse conveyance. The inversion distance can only be set when the inversion setting is valid. The reversing distance is a predetermined distance that the sheet 200 moves when the sheet 200 is reversed. When the sheet 200 is fed backward, the lower conveying roller 64 and the upper conveying roller 12 of the conveying mechanism 20 rotate at a predetermined speed in the reverse direction to the direction when the sheet 200 is conveyed backward.

The third time is a time from the start instruction until the nozzle valve 181 opens the liquid flow path by the air cylinder 182. The fourth time is a time from the stop instruction until the nozzle valve 181 closes the liquid flow path by the air cylinder 182.

The hold setting can be set to either one of valid and invalid. When the holding setting is enabled, the CPU91 controls the holding mechanism 800 to switch the holding mechanism 800 to the holding state when the bonding operation is stopped, and to switch the holding mechanism 800 to the release state when the bonding operation is started. The fifth time and the sixth time can be set only when the hold setting is active. The fifth time is from the start instruction until the holding mechanism 800 is switched to the released state. The sixth time is from the stop instruction until the holding mechanism 800 switches to the holding state.

The enlargement setting can be set to either one of valid and invalid. When the expansion setting is enabled, the CPU91 controls the gap adjustment motor 68 to expand the nozzle gap interval to be larger than the nozzle gap interval of the condition combination when the bonding operation is stopped, and to reduce the nozzle gap interval to the nozzle gap interval of the condition combination when the bonding operation is started. The enlargement interval, the seventh time, and the eighth time can be set only when the enlargement setting is enabled. The expanded interval is a nozzle gap interval when the nozzle gap interval is expanded when the bonding operation is stopped. The expanded interval is larger than the nozzle gap interval of the control conditions of the condition combination table 87. The seventh time is a time from the start instruction until the nozzle gap interval is reduced. The eighth time is a time from the stop instruction until the nozzle gap interval is expanded.

The blow setting can be set to either one of valid and invalid. The blow setting can only be set to be effective when the expansion setting is effective. When the air blow setting is enabled, the CPU91 opens the electromagnetic valve 401 when the bonding operation is stopped, and discharges air from the air discharge port of the nozzle 11 toward the lower sheet 8. The blow air temperature can only be set when the blow air setting is active. The blow temperature can be set to either a high temperature or a low temperature. When the blow air temperature is high, the CPU91 heats the air to be discharged toward the lower sheet 8 with the heater 411. When the blow air temperature is low, the CPU91 does not heat the air.

Specific examples 1 to 3 will be described with reference to FIG. 15. Specific examples 1 to 3 are cases where the adhesive Z is applied to the lower sheets 82 to 84 as the lower sheet 8. The bonding apparatus 1 applies the adhesive Z to the lower specific end 82A to the lower specific end 84A, which are the right ends of the lower sheets 82 to 84. The lower sheet 82 of the specific example 1 of fig. 15 (a) has directionality in stretch and contraction characteristics. The lower specific end 82A of the lower sheet 82 includes points v 1-v 3. The bonding apparatus 1 applies the adhesive Z sequentially through points v1 to v 3. The lower specific end portion 82A is inclined leftward as going from the point v2 toward the point v 3.

The lower specific end 83A of the lower sheet 83 in the specific example 2 of fig. 15 (b) includes points w1 to w 3. The bonding apparatus 1 applies the adhesive Z so as to pass through the points w1 to w3 in this order. The color of the lower sheet 83 changes before and after the point w 2. Therefore, the ease of light transmission differs between the point w2 in the lower specific end portion 83A. The color of the upper specific end portion 6A of the upper sheet 6 to be bonded to the lower sheet 83 also changes before and after the position corresponding to the point w2 of the lower sheet 83. Therefore, in the upper specific end portion 6A, the ease of light transmission differs between the front and rear of the position corresponding to the point w2 of the lower sheet 83.

Lower sheet 84 of specific example 3 of fig. 15 (c) is composed of lower sheet 841 to lower sheet 843. The thicknesses of the lower sheet 841 to the lower sheet 843 gradually increase in the order of the lower sheet 841 to the lower sheet 843. The lower specific end 84A includes points x 1-x 6. The bonding apparatus 1 applies the adhesive Z so as to pass through points x1 to x6 in this order. The lower sheet 84 has a stepped portion in a section from the point x2 to the point x3 and a section from the point x4 to the point x 5. The upper sheet 6 to be bonded to the lower sheet 84 is in the form of a piece of cloth.

The main process is described with reference to fig. 16 to 26. At the start of the main process, the bonding apparatus 1 is in an initial state. At this time, the nozzle 11 is at the close position, the upper transport roller 12 is at the nipping position, the pivot support portion 314 is at the operating position, the lower nipping roller 76 is at the lower spaced position, the upper nipping roller 32 is at the upper spaced position, the rear end of the support frame 61 is above, the holding mechanism 800 is in the unclamped state, and the liquid flow path of the nozzle lever 18 is in the closed state. When the operator turns on the power of the bonding apparatus 1, the CPU91 starts the main process.

As shown in fig. 16, the CPU91 performs initialization processing (S1). The CPU91 drives the

heaters

131 and 132 at the time of initialization processing, sets the value of the variable X stored in the RAM93 to 1, sets the values of the various flags to initial values, and sets the control conditions of the respective mechanisms to the control conditions of the first condition combination of the condition combination table 87. The variable X is a count used by the CPU91 in setting of the condition combination.

The CPU91 determines whether or not the operation unit 19 has a condition combination setting instruction (S11). The condition combination setting instruction is an instruction for setting a condition combination. When the operator has not input the condition combination setting instruction to the operation unit 19 (S11: no), the CPU91 shifts the process to S21. When the operator inputs a condition combination setting instruction to the operation unit 19 (yes in S11), the CPU91 executes the condition combination setting process (S12), and the process proceeds to S21.

Referring to fig. 17, the condition combination setting process will be described. The condition combination setting process is an instruction for setting control conditions for the bonding operation and creating a condition combination. The CPU91 displays a setting screen for the combination of conditions on the display unit 260 (S81). The CPU91 determines whether or not the condition combination number is input to the operation unit 19 (S82). Before the operator inputs the condition combination number to the operation unit 19 (S82: no), the CPU91 stands by. When the operator inputs the condition combination number to the operation unit 19 (yes in S82), the CPU91 acquires the condition combination number input by the operator (S83), and the process proceeds to S91.

The CPU91 determines whether or not there is an instruction to set the lower transport roller speed from the operation unit 19 (S91). When the operator does not input an instruction to set the lower feed roller speed to the operation unit 19 (S91: no), the CPU91 shifts the process to S93. When the operator inputs an instruction to set the lower feed roller speed to the operation unit 19 (yes in S91), the CPU91 sets the lower feed roller speed in accordance with the input to the operation unit 19 (S92), and the process proceeds to S93.

The CPU91 determines whether or not there is an instruction to set the upper transport roller speed from the operation unit 19 (S93). When the operator has not input an instruction to set the upper transport roller speed to the operation unit 19 (S93: no), the CPU91 shifts the process to S97. When the operator inputs an instruction to set the upper transport roller speed to the operation unit 19 (yes in S93), the CPU91 sets the upper transport roller speed in accordance with the input to the operation unit 19 (S94), and the process proceeds to S97.

The CPU91 determines whether or not there is an instruction to set the lower detection threshold value from the operation unit 19 (S97). When the operator does not input an instruction to set the lower detection threshold to the operation unit 19 (S97: no), the CPU91 shifts the process to S99. When the operator inputs an instruction to set the lower detection threshold to the operation unit 19 (yes in S97), the CPU91 sets the lower detection threshold in accordance with the input to the operation unit 19 (S98), and the process proceeds to S99.

The CPU91 determines whether or not there is an instruction to set the upper detection threshold value in the operation unit 19 (S99). When the operator does not input an instruction to set the upper detection threshold to the operation unit 19 (S99: no), the CPU91 shifts the process to S101. When the operator inputs an instruction to set the upper detection threshold to the operation unit 19 (yes in S99), the CPU91 sets the upper detection threshold in accordance with the input to the operation unit 19 (S100), and the process proceeds to S101.

The CPU91 determines whether or not there is an instruction to set the start/stop time combination in the operation unit 19 (S101). When the operator has not input an instruction to set the start/stop time combination to the operation unit 19 (S101: no), the CPU91 shifts the process to S103. When the operator inputs an instruction to set the start/stop combination to the operation unit 19 (yes in S101), the CPU91 sets the start/stop combination corresponding to the start/stop combination table 88 in accordance with the input to the operation unit 19 (S102), and the process proceeds to S103.

The CPU91 determines whether or not there is an instruction to set the film thickness from the operation unit 19 (S103). When the operator has not input an instruction to set the film thickness to the operation unit 19 (no in S103), the CPU91 shifts the process to S105. When the operator inputs an instruction to set the film thickness to the operation unit 19 (yes in S103), the CPU91 sets the film thickness based on the input to the operation unit 19 (S104), and the process proceeds to S105.

The CPU91 determines whether or not there is an instruction to set the nozzle gap interval from the operation unit 19 (S105). When the operator has not input an instruction to set the nozzle gap interval to the operation unit 19 (no in S105), the CPU91 shifts the process to S107. When the operator inputs an instruction to set the nozzle gap interval to the operation unit 19 (yes in S105), the CPU91 sets the nozzle gap interval based on the input to the operation unit 19 (S106), and the process proceeds to S107.

The CPU91 determines whether or not there is an instruction to set a step portion setting in the operation unit 19 (S107). When the operator has not input an instruction to set the step setting to the operation unit 19 (S107: no), the CPU91 shifts the process to S109. When the operator inputs an instruction to set the step setting to the operation unit 19 (yes in S107), the CPU91 sets the step setting to either one of valid and invalid according to the input to the operation unit 19 (S108), and the process proceeds to S109.

The CPU91 determines whether or not there is an instruction to set the pressing force (S109). When the operator has not input an instruction to set the pressing force to the operation unit 19 (no in S109), the CPU91 advances the process to S121. When the operator inputs an instruction to set the pressing force to the operation unit 19 (yes in S109), the CPU91 sets the pressing force in accordance with the input to the operation unit 19 (S110), and the process proceeds to S121.

The CPU91 stores the condition combination for which each control condition has been set in the storage area of the condition combination number acquired at S83 in the condition combination table 87 (S121). The CPU91 clears the setting screen for the combination of conditions currently displayed on the display unit 260 (S122), and returns the process to the main process (see fig. 16).

In the lower sheet 82 of the specific example 1 of fig. 15 (a), the direction of adhesion to the lower sheet 82 changes at the point v 2. In the lower sheet 82, the stretch characteristic is different between a section from the point v1 to the point v2 and a section from the point v2 to the point v 3. Therefore, when the bonding apparatus 1 controls the respective mechanisms in combination under the same condition for the section from the point v1 to the point v3, the adhesive Z may be unevenly adhered between the first section from the point v1 to the point v2 and the second section from the point v2 to the point v 3. Therefore, the operator sets the control conditions of the condition combination so as to switch the lower transport roller speed, the upper transport roller speed, and the start/stop time combination between the first section and the second section, for example. The items switched in the start/stop time combination are, for example, the reverse setting, the reverse distance, the hold setting, the fifth time, and the sixth time.

In the lower sheet 83 of the specific example 2 of fig. 15 (b), the color changes with the point w2 as a boundary, and in the upper sheet 6, the color changes with the position corresponding to the point w2 of the lower sheet 83 as a boundary. In the lower specific end portion 83A, the ease of light transmission differs between a third section from the point w1 to the point w2 and a fourth section from the point w2 to the point w3, and in the upper specific end portion 6A, the ease of light transmission differs between the front and rear of the position corresponding to the point w2 of the lower sheet 83. Therefore, when the bonding apparatus 1 controls the respective mechanisms in combination under the same condition for the section from the point w1 to the point w3, a portion where the adhesive Z is not applied may be generated in the fourth section. Therefore, the operator sets the control conditions of the condition combination so that the lower detection threshold value and the upper detection threshold value are switched between the third section and the fourth section, for example.

The lower sheet 84 of example 3 of fig. 15 (c) is composed of lower sheets 841 to 843 having different thicknesses. In the lower specific end portion 84A, the fifth section from the point x1 to the point x2, the sixth section from the point x3 to the point x4, and the seventh section from the point x5 to the point x6 have no step portion, but the thicknesses thereof are different from each other. The eighth section from the point x2 to the point x3 and the ninth section from the point x4 to the point x5 each have a stepped portion. The interval of the lower sheet 84 from the nozzle 11 changes at the step. Therefore, when the bonding apparatus 1 controls the respective mechanisms in combination under the same condition for the section from the point x1 to the point x6, the nozzle gap interval is constant, and therefore, the lower sheet 84 may come closer to the nozzle 11 to block the liquid discharge port 13, so that the adhesive Z is not easily discharged, and the adhesive Z adhering to the lower sheet 84 may become uneven. Therefore, the operator sets the control conditions of the condition combination so as to switch the nozzle gap interval between the fifth to ninth intervals. The operator also sets the control conditions of the combination of conditions so that the step setting is effectively switched between the fifth section and the sixth section.

As shown in fig. 16, the CPU91 determines whether or not there is an operation instruction from the operation unit 19 (S21). Before the operator inputs an operation instruction to the operation unit 19 (S21: no), the CPU91 stands by. When the operator inputs an operation instruction to the operation section 19 (yes in S21), the CPU91 controls the air cylinder 931 to swing the lower pinch roller 76 from the lower pinch position to the lower separation position, and controls the air cylinder 39 to swing the upper pinch roller 32 from the upper pinch position to the upper separation position (S22). The CPU91 controls the gap adjustment motor 68 to lower the rear end of the support frame 61 and enlarge the nozzle gap (S23).

The CPU91 determines whether there is a roller swing instruction (S31). The roller swing instruction is an instruction to swing the upper conveying roller 12 in the up-down direction. Before the operator inputs a roller swing instruction to the operation unit 19 (S31: no), the CPU91 stands by. When the operator inputs a roller swing instruction to the operation unit 19 (yes in S31), the CPU91 controls the air cylinder 122 to swing the upper transport roller 12 from the nipping position to the upper position (S32). The CPU91 controls the air cylinder 931 to swing the lower grip roller 76 from the lower separated position to the lower grip position (S33). The CPU91 sets the lower edge flag stored in the RAM93 to 1 (S34). When the lower edge flag is 0, it indicates the end of the lower edge control process described later, and when the lower edge flag is 1, it indicates the start of the lower edge control process. When the lower edge flag has been set to 1, the CPU91 still covers the lower edge flag to 1. The initial value of the lower edge flag is 0.

The CPU91 determines whether the arrangement of the lower sheet 8 is completed (S41). Until the operator inputs information indicating that the arrangement of the lower sheets 8 is completed to the operation portion 19 (S41: no), the CPU91 stands by. The lower sheet 8 is disposed on the support plate 57, the nozzle plate 59, and the lower conveying roller 64 by the operator. The lower pinch roller 76 sandwiches the lower sheet 8 between it and the lower surface 317. When the operator inputs information indicating that the arrangement of the lower sheet 8 is completed to the operation unit 19 (yes in S41), the CPU91 controls the gap adjustment motor 68 to move the rear end of the support frame 61 upward to reduce the nozzle gap interval (S42). The nozzle gap interval becomes the nozzle gap interval of the control condition by the driving of the gap adjusting motor 68.

The CPU91 determines whether the arrangement of the upper sheet 6 is completed (S51). Until the operator inputs information indicating that the arrangement of the upper sheets 6 is completed to the operation portion 19 (S51: no), the CPU91 stands by. The operator places the upper sheet 6 on the upper surface 315, the horizontally extending portion of the nozzle 11, and the rear end portion of the lower sheet 8 from above. When the operator inputs information indicating that the arrangement of the upper sheet 6 is completed to the operation portion 19 (S51: yes), the CPU91 controls the air cylinder 39 to swing the upper pinch roller 32 from the upper spaced position to the upper pinch position (S52). The upper nip roller 32 nips the upper sheet 6 between it and the upper surface 315. The CPU91 sets the upper edge flag stored in the RAM93 to 1 (S53). When the upper edge flag is 0, it indicates the end of the upper edge control process described later, and when the upper edge flag is 1, it indicates the start of the upper edge control process. When the upper edge flag has been set to 1, the CPU91 still overwrites the upper edge flag to 1. The initial value of the upper edge flag is 0.

The CPU91 determines whether there is a roller swing instruction (S61). Before the operator inputs a roller swing instruction to the operation unit 19 (S61: no), the CPU91 stands by. When the operator inputs a roller swing instruction to the operation unit 19 (yes in S61), the CPU91 controls the air cylinder 122 to swing the upper transport roller 12 from the upper position to the nipping position (S62). The air cylinder 122 urges the upper conveying roller 12 toward the lower conveying roller 64 with a thrust force corresponding to the pressing force of the control condition. The upper conveying rollers 12 sandwich the lower sheet 8 and the upper sheet 6 therebetween and the lower conveying rollers 64. The CPU91 executes the bonding process (S63).

The bonding process will be described with reference to fig. 18 to 21. As shown in fig. 18, the CPU91 determines whether there is a start instruction by the pedal 7 (S131). When the operator does not step on the pedal 7, the CPU91 determines that there is no start instruction (S131: no) and waits. When the operator steps on the pedal 7, the CPU91 determines that there is a start instruction (S131: yes), and starts timing (S132). The CPU91 sequentially stores the timing results in the RAM 93. The CPU91 controls the pump motor 114 to start the supply of the adhesive Z (S133). The supply mechanism 45 supplies the adhesive Z, which has become a liquid, from the liner to the liquid flow path of the nozzle lever 18 by driving the pump motor 114.

The CPU91 determines whether or not the first time has elapsed since the time measurement started in S132 (S141). The start/stop time combination of the control conditions includes a first time. Until the CPU91 determines that the first time has elapsed (S141: no), the CPU91 shifts the process to S151. When the CPU91 determines that the first time has elapsed (S141: yes), the CPU91 controls the lower conveyance motor 63 and the upper conveyance motor 112, and starts driving of the lower conveyance roller 64 and the upper conveyance roller 12 (S142). The conveying mechanism 20 conveys the sheet 200 to the rear side. The CPU91 shifts the process to S151.

The CPU91 determines whether or not the third time has elapsed since the time measurement started in S132 (S151). The start/stop time combination of the control conditions includes a third time. Until the CPU91 determines that the third time has elapsed (S151: no), the CPU91 shifts the process to S161. When the CPU91 judges that the third time has elapsed (YES in S151), the CPU91 controls the air cylinder 182 to drive the nozzle valve 181 so that the liquid flow path of the nozzle lever 18 is in an open state (S152). The adhesive Z that has become liquid flows to the liquid discharge port 13 through the liquid flow path of the nozzle 11 and the nozzle lever 18. Accordingly, the nozzle 11 discharges the adhesive Z from the liquid discharge port 13.

The CPU91 determines whether the hold flag stored in the RAM93 is 1 (S161). When the holding flag is 0, the holding mechanism 800 is in the released state, and when the holding flag is 1, the holding mechanism 800 is in the held state. The initial value of the hold flag is 0. When the CPU91 determines that the hold flag is 0 (S161: no), the CPU91 shifts the process to S171.

When the CPU91 determines that the hold flag is 1 (S161: yes), the CPU91 determines whether or not the fifth time has elapsed since the time counting started in S132 (S162). The start/stop time combination of the control conditions includes a fifth time. Until the CPU91 determines that the fifth time has elapsed (S162: no), the CPU91 shifts the process to S171. When the CPU91 determines that the fifth time has elapsed (S162: YES), the CPU91 controls the air cylinder 809 to switch the holding member 810 from the holding state to the releasing state (S163). The holding member 810 is separated downward from the lower sheet 8 (see fig. 11). The CPU91 sets the hold flag to 0(S164), and the process proceeds to S171.

The CPU91 determines whether the expansion flag stored in the RAM93 is 1 (S171). When the expansion flag is 0, the nozzle gap interval is the nozzle gap interval of the control condition, and when the expansion flag is 1, the nozzle gap interval is the expansion interval of the start/stop combination. The initial value of the enlargement flag is 0. When the CPU91 determines that the expansion flag is 0 (S171: no), the CPU91 shifts the process to S181.

When the CPU91 determines that the enlargement flag is 1 (S171: yes), the CPU91 determines whether or not the seventh time has elapsed since the time measurement started in S132 (S172). The start/stop time combination of the control conditions includes a seventh time. Until the CPU91 determines that the seventh time has elapsed (S172: no), the CPU91 shifts the process to S181. When the CPU91 determines that the seventh time has elapsed (yes in S172), the CPU91 controls the gap adjustment motor 68 to reduce the nozzle gap interval to the nozzle gap interval of the control condition (S173). The CPU91 sets the expansion flag to 0(S174), and proceeds the process to S181.

The CPU91 determines whether or not the bonding operation has been started (S181). When the lower feed roller 64 and the upper feed roller 12 start to be driven (S142), the liquid discharge port 13 starts to discharge the adhesive Z (S152), the holding mechanism 800 in the holding state is switched to the unclamped state (S163), and the once expanded nozzle gap interval is reduced (S173), the CPU91 determines that the bonding operation has been started. If the holding mechanism 800 is in the released state at the time of the start instruction, the item for switching the holding mechanism 800 in the held state to the released state is not a requirement for starting the bonding operation. If the nozzle gap interval is the nozzle gap interval of the control condition at the time of the start instruction, the item of narrowing the nozzle gap interval that has been expanded does not become a necessary condition for starting the bonding operation. When the CPU91 determines that the bonding operation is not started (S181: no), the CPU91 returns the process to S141.

The CPU91 repeats S141 to S181, starts driving the lower feed roller 64 and the upper feed roller 12 (S142), starts discharging the adhesive Z from the liquid discharge port 13 (S152), switches the holding mechanism 800 in the holding state to the unclamped state (S163), and reduces the nozzle gap interval that has once been expanded (S173). When the CPU91 determines that the bonding operation has started (S181: yes), the CPU91 ends the timer started in S132 (S182) as shown in fig. 19. The CPU91 determines whether or not the step setting of the control condition is valid (S191). When the CPU91 determines that the step portion is set to invalid (S191: no), the CPU91 shifts the process to S221.

When the CPU91 determines that the stepped portion is set to be effective (S191: yes), the CPU91 performs control to appropriately adjust the nozzle gap interval when the thickness of the lower sheet 8 changes. The CPU91 determines whether or not the thickness of the lower sheet 8 has changed based on the detection result of the magnetic sensor 963 (S201). When a non-stepped portion of the lower sheet 8 or a stepped portion of the lower sheet 8 passes between the lower pinch roller 76 and the lower surface 317 of the rotary support 314, the thickness of the lower sheet 8 is constant. Therefore, the extension member 951 does not move in the left-right direction, and the detection result of the magnetic sensor 963 is constant. At this time, the CPU91 determines that there is no change in the thickness of the lower sheet 8 (S201: no), and shifts the process to S211.

The CPU91 determines whether or not the change flag stored in the RAM93 is 1 (S211). When the variation flag is 0, it indicates that the nozzle gap interval is appropriate, and when the variation flag is 1, it indicates that the nozzle gap interval is not appropriate due to the thickness variation of the lower sheet 8. The initial value of the change flag is 0. When the CPU91 determines that the variation flag is 0 (S211: no), the CPU91 shifts the process to S221. When the CPU91 determines that the variation flag is 1 (S211: yes), the CPU91 shifts the process to S212.

When the step portion of the lower sheet 8 enters between the lower pinch roller 76 and the lower surface 317 or retreats from between the lower pinch roller 76 and the lower surface 317, the thickness of the lower sheet 8 changes. Therefore, the extension setting member 951 moves in the left-right direction, and the detection result of the magnetic sensor 963 changes. At this time, the CPU91 determines that the thickness of the lower sheet 8 has changed (yes in S201), and acquires the amount and direction of movement of the lower pinch roller 76 in the up-down direction based on the detection result of the magnetic sensor 963 (S202). The CPU91 starts timing (S203), and sequentially stores the timing results in the RAM 93. The CPU91 sets the variation flag to 1(S204), and proceeds the process to S212.

The CPU91 determines whether or not the variation time has elapsed since the time measurement was started in S203 (S212). The variation time is a time determined by the rotational speed of the lower conveyance roller 64. Until the CPU91 determines that the variation time has elapsed (S212: no), the CPU91 shifts the process to S221. When the CPU91 determines that the variation time has elapsed (yes in S212), the CPU91 controls the driving of the gap adjustment motor 68 to move the support frame 61 in the same direction as the moving direction of the lower pinch roller 76 by the movement amount of the lower pinch roller 76 acquired in S202, and changes the nozzle gap interval (S213). The CPU91 ends the timing started in S203 (S214), and sets the variation flag to 0 (S215). The CPU91 shifts the process to S221.

The CPU91 determines whether or not there is a switching instruction (S221). The switching instruction is an instruction for switching a combination of conditions during execution of the bonding operation. When the operator operates the switch 17, the CPU91 determines that there is a switching instruction. When the CPU91 determines that there is no switching instruction (S221: no), the CPU91 shifts the process to S231. When the CPU91 determines that there is a switch instruction (S221: yes), the CPU91 executes a switch process (S222), and the process proceeds to S231.

In the lower sheet 82 of the specific example 1 of fig. 15 (a), when the bonding apparatus 1 completes bonding of the lower sheet 82 up to the point v2, the operator operates the switch 17 without stopping the bonding operation (S221: yes). At this time, the bonding apparatus 1 switches the combination of conditions and switches the control conditions of the respective mechanisms (S222). In the lower sheet 83 of the specific example 2 of fig. 15 (b), when the bonding apparatus 1 completes bonding of the lower sheet 83 to the point w2 at which the color is switched, the operator operates the switch 17 (S221: yes). At this time, the bonding apparatus 1 switches the combination of conditions and switches the lower detection threshold and the upper detection threshold of the control conditions (S222). In the lower sheet 84 of the specific example 3 of fig. 15 (c), when the bonding apparatus 1 completes bonding of the lower sheet 84 to the point x2, the point x3, the point x4, and the point x5 which are stepped portions, the operator operates the switch 17 (S221: yes). At this time, the bonding apparatus 1 switches the condition combination and the nozzle gap interval of the control condition (S222).

Referring to fig. 22 and 23, the switching process is explained. As shown in fig. 22, the CPU91 adds 1 to the variable X (S311). The CPU91 determines whether or not the xth condition combination exists in the condition combination table 87 (S312). When the CPU91 determines that there is the X-th condition combination in the condition combination table 87 (S312: yes), the CPU91 acquires the control condition of the X-th condition combination from the condition combination table 87 (S313), and the process proceeds to S321. When the CPU91 determines that the X-th condition combination does not exist in the condition combination table 87 (S312: no), the CPU91 sets the variable X to 1(S314), and acquires the control condition of the first condition combination from the condition combination table 87 (S315). The CPU91 shifts the process to S321.

The CPU91 determines whether or not the lower feed roller speed is changed (S321). When the lower conveyance roller speed of the control condition of the X-th combination of conditions is the same as the lower conveyance roller speed before switching, the CPU91 determines that the lower conveyance roller speed is not changed (S321: no), and shifts the process to S323. When the lower transport roller speed of the control condition of the X-th combination of conditions is different from the lower transport roller speed before switching, the CPU91 determines to change the lower transport roller speed (S321: yes). At this time, the CPU91 changes the lower feed roller speed (S322), and the process proceeds to S323.

The CPU91 determines whether or not the upper transport roller speed is changed (S323). When the upper transport roller speed of the control condition of the X-th combination of conditions is the same as the upper transport roller speed before switching, the CPU91 determines that the upper transport roller speed is not changed (S323: no), and shifts the process to S327 (see fig. 23). When the upper transport roller speed of the control condition of the X-th combination of conditions is different from the upper transport roller speed before switching, the CPU91 determines to change the upper transport roller speed (S323: yes). At this time, the CPU91 changes the upper transport roller speed (S324), and the process proceeds to S327.

As shown in fig. 23, the CPU91 determines whether or not the lower detection threshold value is changed (S327). When the lower detection threshold value of the control condition of the X-th combination of conditions is the same as the lower detection threshold value before switching, the CPU91 determines that the lower detection threshold value is not changed (S327: no), and shifts the process to S329. When the lower detection threshold of the control condition of the X-th combination of conditions is different from the lower detection threshold before switching, the CPU91 determines that the lower detection threshold is to be changed (S327: yes). At this time, the CPU91 changes the lower detection threshold (S328) and advances the process to S329.

The CPU91 determines whether or not the upper detection threshold value has been changed (S329). When the upper detection threshold of the control condition of the X-th combination of conditions is the same as the upper detection threshold before switching, the CPU91 determines that the upper detection threshold is not changed (S329: no), and shifts the process to S331. When the upper detection threshold of the control condition of the X-th combination of conditions is different from the upper detection threshold before switching, the CPU91 determines that the upper detection threshold is to be changed (S329: yes). At this time, the CPU91 changes the upper detection threshold (S330), and the process proceeds to S331.

The CPU91 determines whether or not the start/stop time combination is changed (S331). When the start/stop combination of the control conditions of the X-th condition combination is the same as the start/stop combination before switching, the CPU91 determines that the start/stop combination is not to be changed (S331: no), and shifts the process to S333. When the start/stop combination of the control conditions of the X-th condition combination is different from the start/stop combination before switching, the CPU91 determines that the start/stop combination is to be changed (S331: yes). At this time, the CPU91 changes the start/stop time combination and changes the corresponding various settings (S332). The CPU91 shifts the process to S333.

The CPU91 determines whether or not the film thickness is changed (S333). When the film thickness of the control condition of the X-th combination of conditions is the same as the film thickness before switching, the CPU91 determines that the film thickness is not to be changed (S333: no), and shifts the process to S335. When the film thickness of the control condition of the X-th combination of conditions is different from the film thickness before switching, the CPU91 judges that the film thickness is to be changed (S333: YES). At this time, the CPU91 changes the film thickness (S334), and the process proceeds to S335.

The CPU91 determines whether or not the nozzle gap interval is changed (S335). When the nozzle gap interval of the control condition of the X-th combination of conditions is the same as the nozzle gap interval before switching, the CPU91 determines that the nozzle gap interval is not changed (S335: no), and shifts the process to S337. When the nozzle gap interval of the control condition of the X-th combination of conditions is different from the nozzle gap interval before switching, the CPU91 determines to change the nozzle gap interval (S335: yes). At this time, the CPU91 changes the nozzle gap interval (S336) and shifts the process to S337.

The CPU91 determines whether or not to change the step setting (S337). When the step setting of the control condition of the X-th combination of conditions is the same as the step setting before switching, the CPU91 determines that the step setting is not changed (S337: no), and shifts the process to S339. When the step setting of the control condition of the X-th combination of conditions is different from the step setting before switching, the CPU91 determines to change the step setting (S337: yes). At this time, the CPU91 changes the step setting (S338) and proceeds to S339.

The CPU91 determines whether or not the pressing force is changed (S339). When the pressing force of the control condition of the X-th combination of conditions is the same as the pressing force before switching, the CPU91 determines that the pressing force is not changed (S339: no), and returns the process to the bonding process (see fig. 19). When the pressing force of the control condition of the X-th combination is different from the pressing force before switching, the CPU91 determines that the pressing force is to be changed (S339: yes). At this time, the CPU91 changes the pressing force (S340) and returns the process to the bonding process.

As shown in fig. 19, the CPU91 determines whether or not there is a stop instruction by the pedal 7 (S231). When the operator does not return the pedal 7 to the neutral position, the CPU91 determines that there is no stop instruction (S231: no), and returns the process to S191. Until the operator returns the pedal 7 to the neutral position, the CPU91 repeats S191 to S231. When the operator returns the pedal 7 to the neutral position, the CPU91 determines that there is a stop instruction (S231: yes), and starts timing as shown in fig. 20 (S232). The CPU91 sequentially stores the timing results in the RAM 93. The CPU91 controls the pump motor 114 to stop driving the pump motor 114, and the supply mechanism 45 stops supplying the adhesive Z from the liner to the liquid flow path of the nozzle lever 18 (S233).

The CPU91 determines whether or not the second time has elapsed since the time counting started in S232 (S241). The start/stop time combination of the control conditions includes a second time. Until the CPU91 determines that the second time has elapsed (S241: no), the CPU91 shifts the process to S251. When the CPU91 determines that the second time has elapsed (S241: yes), the CPU91 controls the lower conveyance motor 63 and the upper conveyance motor 112 to stop the driving of the lower conveyance roller 64 and the upper conveyance roller 12 (S242).

The CPU91 determines whether the reverse setting is valid (S243). When the CPU91 determines that the reverse setting of the start/stop time combination is invalid (S243: no), the CPU91 shifts the process to S251. When the CPU91 determines that the reverse setting is valid (S243: yes), the CPU91 executes a conveying roller reverse driving process (S244). The CPU91 controls the lower conveyance motor 63 and the upper conveyance motor 112 in the conveyance roller reverse driving process to rotate the lower conveyance roller 64 and the upper conveyance roller 12 at a prescribed speed in the reverse direction of the direction when driven by S142. The conveyance mechanism 20 feeds the sheet 200 upside down. After the CPU91 reverses the sheet 200 by the amount of the reversing distance, the lower conveyance motor 63 and the upper conveyance motor 112 are controlled, and the driving of the lower conveyance roller 64 and the upper conveyance roller 12 is stopped.

The CPU91 determines whether or not the fourth time has elapsed since the time was counted in S232 (S251). The start/stop time combination of the control conditions includes a fourth time. Until the CPU91 determines that the fourth time has elapsed (S251: no), the CPU91 shifts the process to S261. When the CPU91 judges that the fourth time has elapsed (YES in S251), the CPU91 controls the air cylinder 182 to drive the nozzle valve 181 so that the liquid flow path of the nozzle lever 18 is closed. The nozzle 11 stops discharging the adhesive Z (S252). The CPU91 shifts the process to S261.

The CPU91 determines whether the hold setting of the start/stop time combination is valid (S261). When the CPU91 determines that the hold setting is invalid (S261: no), the CPU91 shifts the process to S271 (see fig. 21). When the CPU91 determines that the hold setting is valid (S261: yes), the CPU91 determines whether or not the sixth time has elapsed since the time counting started in S232 (S262). The start/stop time combination includes a sixth time. Until the CPU91 determines that the sixth time has elapsed (S262: no), the CPU91 shifts the process to S271. When the CPU91 determines that the sixth time has elapsed (S262: YES), the CPU91 controls the cylinder 809 to switch the holding member 810 from the released state to the held state (S263). Holding member 810 sandwiches lower sheet 8 between it and lower surface 317 of rotation support 314 (see fig. 10). The CPU91 sets the hold flag to 1(S264), and the process proceeds to S271.

As shown in fig. 21, the CPU91 determines whether the enlargement setting of the start/stop time combination is valid (S271). When the CPU91 determines that the enlargement setting is invalid (S271: no), the CPU91 shifts the process to S281. When the CPU91 determines that the enlargement setting is enabled (S271: yes), the CPU91 determines whether the eighth time has elapsed since the time counting started in S232 (S272). The start/stop time combination includes an eighth time. Until the CPU91 determines that the eighth time has elapsed (S272: no), the CPU91 shifts the process to S281. When the CPU91 determines that the eighth time has elapsed (YES in S272), the CPU91 controls the gap adjusting motor 68 to expand the nozzle gap interval to the expanded interval (S273). The lower sheet 8 leaves the lower surface of the nozzle 11. The CPU91 sets the expansion flag to 1(S274), and the process proceeds to S281.

The CPU91 determines whether or not the combined air blow setting at start/stop is valid (S281). When the CPU91 determines that the air blow setting is invalid (S281: no), the CPU91 shifts the process to S291. When the CPU91 determines that the air blow setting is valid (S281: yes), the CPU91 executes an air blow process (S282), and the process proceeds to S291.

Referring to fig. 24, the air blowing process is explained. The air-blowing process is a process of: after the nozzle gap interval is expanded (see S273 and fig. 21), air is discharged from the air discharge port of the nozzle 11 toward the lower sheet 8, and the lower sheet 8 is separated from the nozzle 11. The CPU91 determines whether the air blowing flag stored in the RAM93 is 1 (S351). When the air blow flag is 0, it indicates that air is not discharged from the air discharge port, and when the air blow flag is 1, it indicates that air is discharged from the air discharge port toward the lower sheet 8. The initial value of the air blow flag is 0. When the CPU91 determines that the air blow flag is 1 (S351: YES), the CPU91 shifts the process to S381.

When the CPU91 determines that the air blow flag is 0 (S351: NO), the CPU91 determines whether the air blow temperature of the start/stop combination is high (S361). When the CPU91 determines that the temperature of the blown air is low (S361: NO), the CPU91 shifts the process to S371. When the CPU91 determines that the temperature of the blown air is high (YES in S361), the CPU91 starts heat generation of the heater 411 (S362) and heats the air in the internal flow path of the air discharge mechanism. The CPU91 shifts the process to S371.

The CPU91 determines whether the expansion flag stored in the RAM93 is 1 (S371). When the CPU91 determines that the expansion flag is 0 (S371: no), the nozzle gap interval is reduced, and the CPU91 returns the process to the bonding process (see fig. 21). When the CPU91 determines that the expansion flag is 1 (S371: yes), the nozzle gap interval is expanded, the CPU91 starts timing (S372), and the timing results are sequentially stored in the RAM 93. The CPU91 opens the solenoid valve 401 and supplies air from the air compressor to the air discharge port. The nozzle 11 starts blowing air to the lower sheet 8 (S373). The CPU91 sets the air blow flag to 1(S374), and the process proceeds to S381.

The CPU91 determines whether or not the air-blowing time has elapsed since the time measurement was started in S372 (S381). The air blowing time is a prescribed time stored in the storage device 94. Until the CPU91 determines that the air blowing time has elapsed (S381: no), the CPU91 returns the process to the bonding process (see fig. 21). When the CPU91 determines that the air-blow time has elapsed (YES in S381), the CPU91 closes the solenoid valve 401 and ends the air blowing from the nozzle 11 (S382). The CPU91 ends the timing started in S372 (S383), and sets the air blow flag to 0 (S384). The CPU91 determines whether or not the combined blow air temperature at start/stop is a high temperature (S391). When the CPU91 determines that the blow air temperature is low (S391: NO), the CPU91 returns the process to the bonding process. When the CPU91 determines that the temperature of the blown air is high (YES in S391), the CPU91 ends the heat generation of the heater 411 (S392) and returns the process to the bonding process.

As shown in fig. 21, the CPU91 determines whether or not the bonding operation has been stopped (S291). When the lower feed roller 64 and the upper feed roller 12 are stopped from being driven (S242 and S244), the discharge of the adhesive Z from the liquid discharge port 13 is stopped (S252), the holding mechanism 800 in the unclamped state is switched to the holding state (S263), the nozzle gap interval is expanded (S273), and when the discharge of air from the air discharge port is stopped (S382), the CPU91 determines that the bonding operation has been stopped. If the start/stop combination holding setting is disabled at the time of the stop instruction, the item for which the holding mechanism 800 in the unclamped state is switched to the holding state does not become a necessary condition for stopping the bonding operation. If the enlargement of the start/stop time combination is set to be invalid at the time of the stop instruction, the enlargement of the nozzle gap interval does not become a necessary condition for stopping the bonding operation. If the combined air blowing setting of start and stop at the time of stop instruction is invalid, the item for ending the air blowing from the air outlet does not become a necessary condition for stopping the bonding operation. When the CPU91 determines that the bonding operation is not being stopped (S291: no), the CPU91 returns the process to S241 (see fig. 20).

The CPU91 repeats S241 to S291, stops driving the lower conveyance roller 64 and the upper conveyance roller 12 (S242, S244), stops discharging the adhesive Z from the liquid discharge port 13 (S252), switches the holding mechanism 800 in the unclamped state to the holding state (S263), enlarges the nozzle gap interval (S273), and ends blowing out the air from the air discharge port (S382). When the CPU91 determines that the bonding operation has stopped (yes in S291), the CPU91 ends the timer started in S232 (S292). The CPU91 determines whether or not there is a start instruction by the pedal 7 (S301). When the operator steps on the pedal 7, the CPU91 determines that there is a start instruction (S301: yes), and returns the process to S132 (see fig. 18).

When the operator does not step on the pedal 7, the CPU91 determines that there is no start instruction (S301: no), and determines whether there is an end instruction by the pedal 7 (S302). When the operator does not step back on the pedal 7, the CPU91 determines that there is no end instruction (S302: no), and returns the process to S301. When the operator steps back on the pedal 7, the CPU91 determines that there is an end instruction (S302: yes), and determines whether the hold flag is 1 (S303). When the CPU91 determines that the hold flag is 0 (S303: no), the CPU91 returns the process to the main process (see fig. 16). When the CPU91 determines that the holding flag is 1 (S303: YES), the CPU91 switches the holding mechanism 800 in the held state to the released state (S304). The CPU91 sets the hold flag to 0(S305), and returns the process to the main process.

As shown in fig. 16, the CPU91 sets the lower edge flag and the upper edge flag stored in the RAM93 to 0 (S64). The CPU91 determines whether there is an operation to cut off the power supply of the bonding apparatus 1 (S71). When the CPU91 determines that there is no operation to turn off the power supply (S71: no), the CPU91 shifts the process to S11. The operator takes out the bonded lower sheet 8 and upper sheet 6. The sheet 200 made by bonding the lower specific end portion 8A and the upper specific end portion 6A together is completed. The operator can set a condition combination by inputting a condition combination setting instruction through the operation unit 19 (S12). The bonding apparatus 1 performs S11 to S71 by the CPU91 to bond the new lower sheet 8 and the upper sheet 6. When the CPU91 determines that there is an operation to turn off the power supply (S71: yes), the CPU91 ends the main process.

Referring to fig. 25, the lower edge control process is explained. The CPU91 executes the lower edge control processing in parallel with the main processing. The CPU91 determines whether or not the lower edge flag stored in the RAM93 is 1 (S401). When the CPU91 determines that the lower edge flag is 0 (S401: NO), the CPU91 stands by.

When the lower edge flag is set to 1 in S34 (see fig. 16) of the main process (S401: yes), the CPU91 determines whether or not the detection result of the lower detection section 78 is greater than the lower detection threshold of the control condition (S411). When the CPU91 determines that the detection result of the lower detection unit 78 is greater than the lower detection threshold (S411: yes), the CPU91 controls the lower pinch motor 72 to rotate the lower pinch roller 76 in the first output direction (S412). The first feeding direction is a rotational direction of the lower pinch roller 76 when the upper end of the lower pinch roller 76 is directed rightward. The CPU91 shifts the process to S421. When the CPU91 determines that the detection result of the lower detection unit 78 is equal to or less than the lower detection threshold (S411: no), the CPU91 controls the lower pinch motor 72 to rotate the lower pinch roller 76 in the second output direction (S413). The second output direction is the reverse of the first output direction. The CPU91 shifts the process to S421.

The CPU91 determines whether the lower edge flag is 0 (S421). Until the lower edge flag becomes 0 in S64 (see fig. 16) of the main process (S421: no), the CPU91 shifts the process to S411 and repeats S411 to S421. When the lower edge flag is changed to 0 by S64 of the main process (S421: yes), the CPU91 stops the driving of the lower grip motor 72 (S422). The CPU91 returns the process to S401 and stands by.

Referring to fig. 26, the top edge control process is explained. The CPU91 executes the upper edge control processing in parallel with the main processing. The CPU91 determines whether the upper edge flag stored in the RAM93 is 1 (S431). When the CPU91 determines that the upper edge flag is 0 (S431: NO), the CPU91 stands by.

When the upper edge flag is set to 1 in S53 (see fig. 16) of the main process (S431: yes), the CPU91 determines whether or not the detection result of the upper detection unit 85 is greater than the upper detection threshold of the control condition (S441). When the CPU91 determines that the detection result of the upper detection unit 85 is greater than the upper detection threshold (yes in S441), the CPU91 controls the upper pinch motor 38 to rotate the upper pinch roller 32 in the third output direction (S442). The third feeding direction is a rotational direction of the upper pinch roller 32 when the lower end of the upper pinch roller 32 goes to the left. The CPU91 shifts the process to S451. When the CPU91 determines that the detection result of the upper detection unit 85 is equal to or less than the upper detection threshold (S441: no), the CPU91 controls the upper pinch motor 38 to rotate the upper pinch roller 32 in the fourth output direction (S443). The fourth output direction is the reverse of the third output direction. The CPU91 shifts the process to S451.

The CPU91 determines whether the upper edge flag is 0 (S451). Until the upper edge flag becomes 0 in S64 (see fig. 16) of the main process (S451: no), the CPU91 shifts the process to S441 and repeats S441 to S451. When the upper edge flag is changed to 0 by S64 of the main process (S451: yes), the CPU91 stops the driving of the upper grip motor 38 (S452). The CPU91 returns the process to S431 and stands by.

The CPU91 repeats S411 to S421 of the lower edge control process and S441 to S451 of the upper edge control process during the bonding process. Therefore, the bonding apparatus 1 can control the length in the left-right direction of the lower specific end portion 8A and the upper specific end portion 6A overlapped in the up-down direction within a certain range.

The bonding apparatus 1 has a nozzle 11, a supply mechanism 45, a conveyance mechanism 20, and a CPU 91. The adhesive Z is discharged from the nozzle 11. The supply mechanism 45 supplies the adhesive Z to the nozzle 11. The conveying mechanism 20 has a lower conveying mechanism 50 and an upper conveying mechanism 70, and the lower sheet 8 and the upper sheet 6 are conveyed by the conveying mechanism 20. The CPU91 executes the bonding operation, and each mechanism is controlled according to the control conditions during the execution of the bonding operation. The bonding apparatus 1 further has a storage device 94 and a switch 17. The storage device 94 stores a condition combination table 87, and the condition combination table 87 includes a plurality of condition combinations as combinations of control conditions. A switch 17 inputs a switching instruction for switching a combination of conditions during execution of the bonding operation. When there is an input of a switching instruction by the switch 17 (yes in S221), the CPU91 executes a switching process (S222) to switch the condition combination. The bonding apparatus 1 switches the condition combination in accordance with the sheet 200 to be bonded by the operation of the switch 17, thereby collectively switching the control conditions included in the condition combination. Therefore, the bonding apparatus 1 can easily switch a plurality of control conditions at the same time.

The lower conveyance mechanism 50 has a lower conveyance roller 64 and a lower conveyance motor 63. The lower feed roller 64 rotates about a rotation shaft 641 extending in the left-right direction. The lower conveyance motor 63 rotates the lower conveyance roller 64. The upper conveyance mechanism 70 has an upper conveyance roller 12 and an upper conveyance motor 112. The upper feed roller 12 rotates about a rotation shaft extending in the left-right direction. The upper conveyance motor 112 rotates the upper conveyance roller 12. The CPU91 controls the rotation of the lower conveyance roller 64 and the rotation of the upper conveyance roller 12 during execution of the bonding action. The control conditions include the speed at which the lower conveyance roller 64 rotates, i.e., the lower conveyance roller speed, and the speed at which the upper conveyance roller 12 rotates, i.e., the upper conveyance roller speed. Therefore, when the material and the like of the sheet 200 change during execution of the bonding operation, the bonding apparatus 1 can still convey the sheet 200 at a speed appropriate for the sheet.

The bonding apparatus 1 has a lower clamp mechanism 80 and an upper clamp mechanism 30. The lower nip mechanism 80 has a lower nip roller 76 and a lower detection portion 78. The lower pinch roller 76 sandwiches the lower sheet 8 between the lower pinch roller and the rotation support portion 314, and the lower pinch roller 76 rotates about the shaft portion 75 extending in the front-rear direction. The lower detection portion 78 detects whether or not the lower sheet 8 is at the lower detection position. The upper nip mechanism 30 has an upper nip roller 32 and an upper detection section 85. The upper nip roller 32 sandwiches the upper sheet 6 between the upper nip roller and the rotation support portion 314, and the upper nip roller 32 rotates about the rotation shaft 33 extending in the front-rear direction. The upper detection unit 85 detects whether or not the upper sheet 6 is at the upper detection position. During the execution of the bonding operation, the CPU91 rotates the lower pinch roller 76 based on the detection result of the lower detection unit 78 to move the lower sheet 8 in the left-right direction (S412, S413), and rotates the upper pinch roller 32 based on the detection result of the upper detection unit 85 to move the upper sheet 6 in the left-right direction (S442, S443). The control conditions include a lower detection threshold used when the lower detection portion 78 detects whether or not the lower sheet 8 is at the lower detection position, and an upper detection threshold used when the upper detection portion 85 detects whether or not the upper sheet 6 is at the upper detection position. Therefore, even when the material and the like of the sheet 200 change during the execution of the bonding operation, the bonding apparatus 1 can be switched between the lower detection threshold of the lower detection section 78 and the upper detection threshold of the upper detection section 85 appropriate for the sheet 200, and the adhesive Z can be appropriately applied to the sheet 200.

The bonding apparatus 1 includes a pedal 7, and the pedal 7 inputs a start instruction and a stop instruction by an operation of an operator. The control conditions include a start/stop combination, which is a combination of controls of the respective mechanisms that operate in accordance with an instruction from the pedal 7. The start/stop time combination includes a first time at which the feed mechanism 20 starts driving at the start of the bonding operation, a third time at which the feed mechanism 45 starts driving at the start of the bonding operation, a second time at which the feed mechanism 20 stops driving at the stop of the bonding operation, and a fourth time at which the feed mechanism 45 stops driving at the stop of the bonding operation. For example, when the feed mechanism 45 and the conveyance mechanism 20 start or stop driving at the same time at the start and stop of the bonding operation, the lower sheet 8 has a larger amount of the adhesive Z adhered to a portion closer to the nozzle 11 at the time of interruption than to other portions. Therefore, the adhesion force of the adhesive Z may be uneven between the portion close to the nozzle 11 and another portion. When the bonding operation is interrupted and then resumed, the bonding apparatus 1 can resume bonding to the sheet 200 under the control conditions suitable for the sheet 200. Therefore, the bonding apparatus 1 can suppress the adhesive Z from being unevenly adhered to the sheet 200 due to the interruption of the bonding operation.

The start/stop time combination includes a combination of a reverse setting that sets the transport mechanism 20 to either one of enable and disable the reverse feeding of the lower sheet 8 and the upper sheet 6 when the bonding operation is stopped, and a reverse distance that is a distance for performing the reverse feeding. During the execution of the bonding operation, the portion of the lower sheet 8 between the nozzle 11 and the lower feed roller 64 is stretched in the front-rear direction by the resistance due to the viscosity of the adhesive Z, and a tension is applied. After the adhesive operation is interrupted, the discharge of the adhesive Z is stopped, and the tension that has been applied to the lower sheet 8 is eliminated, and the lower sheet 8 in the stretched state may move in the front-rear direction. When the bonding operation is interrupted and then resumed, the bonding apparatus 1 can resume bonding to the sheet 200 under the control conditions suitable for the sheet 200. Therefore, the bonding apparatus 1 can suppress the adhesive Z from being unevenly adhered to the sheet 200 due to the interruption of the bonding operation.

The bonding apparatus 1 has a holding mechanism 800. The holding mechanism 800 has a holding member 810 and a cylinder 809. The holding member 810 is switched by moving to a holding state in which the lower sheet 8 is held and a released state in which the holding of the lower sheet 8 is released. The air cylinder 809 moves the holding member 810. When the start/stop combination holding is set to be effective when the bonding operation is stopped, the CPU91 switches the holding mechanism 800 to the holding state (S263), and when the holding mechanism 800 is in the holding state when the bonding operation is started, the CPU91 switches the holding mechanism 800 to the release state (S163). The start/stop time combination includes a fifth time until the holding mechanism 800 is switched to the released state when the bonding action is started and a sixth time until the holding mechanism 800 is switched to the held state when the bonding action is stopped. In some cases, during the execution of the bonding operation, the lower sheet 8 may be moved in the front-rear direction after the bonding operation is interrupted by a resistance due to the viscosity of the adhesive Z. The bonding apparatus 1 can suppress the movement of the portion of the sheet 200 at the position to which the adhesive Z is to be adhered due to tension when the bonding operation is interrupted by the holding mechanism 800. The start/stop time combination includes control of holding or releasing of holding of the holding mechanism 800. Therefore, the bonding apparatus 1 can suppress the adhesive Z from being unevenly adhered to the sheet 200 due to the interruption of the bonding operation.

The bonding apparatus 1 includes a gap adjusting portion 77, and the gap adjusting portion 77 includes a gap adjusting motor 68. The gap adjustment motor 68 moves the support frame 61 of the lower conveyance mechanism 50 up and down. If the expansion of the start/stop combination is set to be effective when the bonding operation is stopped, the CPU91 expands the nozzle gap interval (S273), and if the nozzle gap interval is expanded when the bonding operation is started, the CPU91 reduces the nozzle gap interval (S173). The start/stop time combination includes a seventh time period until the nozzle gap interval is reduced at the start of the bonding operation, an eighth time period until the nozzle gap interval is expanded at the stop of the bonding operation, and an expanded interval which is the nozzle gap interval at the expansion. During the execution of the bonding operation, the nozzle 11 is heated to a high temperature by the heat of the nozzle lever 18 generated by the heating of the heater 132 provided in the nozzle lever 18. When the bonding operation is stopped, the adhesive Z adhering to the portion of the lower sheet 8 close to the nozzle 11 has a lower viscosity than the adhesive Z adhering to the other portion due to the temperature of the nozzle 11, and easily penetrates into the lower sheet 8. Therefore, the adhesion force of the adhesive Z may be uneven between the portion of the lower sheet 8 close to the nozzle 11 and other portions. The bonding apparatus 1 can suppress the degree of non-uniformity of the penetration of the adhesive Z adhering to the lower sheet 8 into the lower sheet 8 by controlling the expansion or contraction of the nozzle gap interval. Therefore, the bonding apparatus 1 can suppress the adhesive Z from being unevenly adhered to the lower sheet 8 due to the interruption of the bonding operation.

The control conditions include nozzle gap spacing. Therefore, when the thickness of the sheet 200 changes during the execution of the bonding operation, the bonding apparatus 1 can still bond the sheet 200 with the nozzle gap interval adapted to the sheet 200 changed.

The bonding apparatus 1 includes a position detecting unit 950, and the position detecting unit 950 detects a change in thickness of the lower sheet 8. The control condition includes a step setting. The step setting can be set to either one of the valid and invalid. If the step portion is set to be effective, the CPU91 changes the nozzle gap interval when the position detection unit 950 detects a change in the thickness of the lower sheet 8 (S213). When the lower sheet 8 has a stepped portion, the bonding apparatus 1 detects a change in the thickness of the lower sheet 8 due to the stepped portion by the position detection portion 950, and changes the nozzle gap interval according to the thickness of the stepped portion. Therefore, the bonding apparatus 1 can suppress the adhesive Z from unevenly adhering to the lower sheet 8.

The supply mechanism 45 has a pump motor 114, and the supply mechanism 45 supplies the adhesive Z to the nozzle 11 by driving the pump motor 114. The control conditions include the thickness of the adhesive Z discharged from the nozzle 11 in the vertical direction, i.e., the film thickness. The CPU91 can control the film thickness by controlling the pump motor 114. Therefore, the bonding apparatus 1 can bond the sheet 200 with the thickness of the adhesive Z suitable for the bonding operation.

The bonding apparatus 1 has a cylinder 122. The air cylinder 122 urges the upper conveying roller 12 toward the lower conveying roller 64. The upper conveying rollers 12 press the lower sheet 8 and the upper sheet 6 between them and the lower conveying rollers 64 with a magnitude of the pressing force. The control condition includes a pressing force. The CPU91 can control the pressing force by controlling the air cylinder 122. Therefore, the bonding apparatus 1 can convey the sheet 200 with a pressing force suitable for the bonding operation.

The CPU91 executes a condition combination setting process of setting a condition combination (S12). The CPU91 sets the control conditions of the condition combinations by the condition combination setting processing, and stores the control conditions in the condition combination table 87 stored in the storage device 94. In the condition combination setting process, not only the condition combination at the start of the bonding operation but also the control condition of the condition combination switched by the switching process can be set. Therefore, when the bonding apparatus 1 bonds the sheet 200 of the same material as the sheet 200 bonded in the previous job after the job of bonding the sheet 200 is completed, the same bonding operation as in the previous job can be easily performed.

The present invention is not limited to the above-described embodiments. The structure and the number of the devices of the bonding apparatus 1 may be changed as appropriate. The type of the bonding apparatus 1 may be changed as appropriate. The bonding apparatus 1 may not include at least one of the lower clamping mechanism 80, the upper clamping mechanism 30, the holding mechanism 800, the gap adjusting portion 77, the position detecting portion 950, the air cylinder 122, and the air discharge mechanism.

The liquid discharge port 13 may be provided above the horizontally extending portion of the nozzle 11. In this case, the nozzle 11 discharges the adhesive Z to the upper sheet 6. The conveying mechanism 20 may also have a conveying belt in place of the lower conveying roller 64 and the nozzle lower roller 65. The conveyor belt is disposed below the nozzles 11.

The lower nip mechanism 80 may also have a drive belt instead of the lower nip roller 76. The upper nip mechanism 30 may also have a drive belt instead of the upper nip roller 32. The belt is disposed in front of the nozzle 11. The lower clamp mechanism 80 may have a transmissive photosensor, a CCD camera, or the like instead of the lower detection unit 78. The upper clamp mechanism 30 may have a transmissive photosensor, a CCD camera, or the like instead of the upper detection unit 85. The upper reflection plate may be provided on the upper surface 315 of the rotation support portion 314. The lower detection threshold and the upper detection threshold may be constant values.

The holding member 810 may be arranged in the front-rear direction with at least a part of the liquid discharge port 13, or may be displaced in the vertical direction with respect to the liquid discharge port 13, as a holding position when holding the lower sheet 8 between the holding member and the rotation support 314. The holding member 810 may hold the lower sheet 8 between it and a member other than the rotation support portion 314, or the holding position and the liquid discharge port 13 may not be aligned in the front-rear direction. The holding member 810 may be spherical provided above the shaft 75, or may be cylindrical extending in the left-right direction above the shaft 75. The holding member 810 may hold the upper sheet 6 by sandwiching the upper sheet 6 between it and the rotation support portion 314.

The holding member 810 may hold the lower sheet 8 without directly contacting the lower sheet 8. For example, the holding member 810 that is switched from the unclamped state to the held state may be moved upward, and may be brought into contact with the lower pinch roller 76 at the lower pinch position from below to bias the lower pinch roller 76 upward. At this time, the holding member 810 indirectly holds the lower sheet 8 by sandwiching the lower sheet 8 between the holding member 810 and the turn support 314 via the lower pinch roller 76. When the lower pinch roller 76 sandwiches the lower sheet 8 between it and the rotary support 314 to hold the lower sheet 8, the holding mechanism 800 including the holding member 810 may be omitted. It is sufficient to provide a driving unit (such as an air cylinder) for biasing the lower nip roller 76 upward. In this case, the lower pinch roller 76 is an example of the holding member of the present invention, and the driving portion is an example of the holding driving portion of the present invention.

The gap adjusting unit 77 may change the nozzle gap interval by moving the nozzle 11 in the vertical direction. In this case, the gap adjusting unit 77 may be integrated with the nozzle swing mechanism 22.

The position detection unit 950 may detect a change in the thickness of the top sheet 6. The magnet may be an electromagnet instead of a permanent magnet. The magnetic sensor 963 may be a hall element or other sensor instead of the MR element. The other sensor is preferably, for example, a proximity sensor (inductive proximity sensor, capacitive proximity sensor, laser displacement meter, etc.). The proximity sensor is a generic term for a sensor capable of detecting the position of an object to be detected in a non-contact manner.

The upper transport roller 12 may be biased to the lower transport roller 64 by an electric cylinder or the like instead of the air cylinder 122. The bonding apparatus 1 may include a biasing mechanism for biasing the upper transport roller 12 by the lower transport roller 64.

The bonding apparatus 1 may include an air compressor for supplying air to the air discharge mechanism. Instead of opening and closing the internal flow path of the air discharge mechanism, the electromagnetic valve 401 may open and close the air flow path, the air discharge port, and the like of the nozzle 11. Instead of using the solenoid valve 401, the supply of air to the air outlet and the stop of the supply may be switched by a ball valve. The bonding apparatus 1 may not have the solenoid valve 401. The heater 411 may be provided in the nozzle or the like instead of the air discharge mechanism. The bonding apparatus 1 may not have the heater 411. The air outlet of the nozzle 11 may be provided at an upper portion of the horizontally extending portion. In this case, the nozzle 11 discharges air toward the upper sheet 6.

Instead of obtaining the output value of the switch 17, the bonding apparatus 1 may obtain the output value of a program timer or the like as a switching instruction. In this case, the program timer automatically inputs a switching instruction to the CPU91 when the counted time reaches a predetermined time. The bonding apparatus 1 may acquire the rotation amount of the upper transport roller 12 or the lower transport roller 64 as a switching instruction. In this case, an encoder may be provided on the drive shaft of the upper conveyance motor 112 or the lower conveyance motor 63, and the CPU91 may automatically input a switching instruction when the rotation amount of the upper conveyance roller 12 or the lower conveyance roller 64 based on the output value of the encoder reaches a predetermined value.

Other control conditions may be added to the condition combination. The control conditions may also include a speed ratio instead of the upper conveyor roller speed. In this case, the speed at which the upper transport roller 12 rotates during the bonding operation is determined by the lower transport roller speed and the speed ratio under the control conditions. Therefore, when the orientation or the like of the sheet 200 changes during execution of the bonding operation, the bonding apparatus 1 can still convey the sheet 200 at an appropriate speed. Likewise, the control conditions may also include a speed ratio instead of the lower conveyor roller speed.

The condition combination may include any two or more of the lower conveyance roller speed, the upper conveyance roller speed, the lower detection threshold, the upper detection threshold, the start/stop time combination, the film thickness, the nozzle gap interval, the step portion setting, the pressing force, and other control conditions.

When the end instruction is given, the CPU91 may control each mechanism according to a control condition of a condition combination specified in the next bonding operation. For example, when the end instruction is present, the variable X may be set to 1, and the condition combination may be switched to the first condition combination in the condition combination table 87. In this case, the first combination of conditions is an example of the combination at the beginning of the present invention. The combination of conditions other than the first combination is an example of the combination in operation of the present invention.

The order of switching the condition combinations may not be based on the condition combination numbers. The operator may designate the order of the condition combinations before performing the bonding operation, and may switch the condition combinations in the designated order in accordance with the operation of the switch 17.

The first time to the eighth time of the start/stop time combination may be a predetermined time. When the first time is set as the predetermined time, the third time, the fifth time, and the seventh time can be set with reference to the predetermined first time, and therefore, the operator can easily set the times of the third time, the fifth time, and the seventh time. The start/stop time combination may include the variation time in S212 and the air blowing time in S381. In this case, the variation time can be set when the step portion is set to be effective, and the air blow time can be set when the air blow is set to be effective.

It is also possible to set the conditions of the respective controls combined at the start/stop. It is desirable that the setting process of the conditions of each control of the start/stop time combination is executed before the condition combination setting process (S12). Desirably, the set setting processing is stored in the start/stop-time combination table 88.

A program including instructions for executing the main processing and the like, the condition combination table 87, and the start/stop-time combination table 88 may be stored in the storage device 94 before the CPU91 executes the program. Therefore, the program acquisition method, the acquisition path, and the device storing the program can be appropriately changed. The program or the like may be received from another device via a cable or wireless communication, or may be stored in a storage device such as a nonvolatile memory. Other devices include, for example, servers connected via a communications network.

Part or all of the steps of the main processing and the like may be performed by other electronic devices (e.g., ASIC). Each step of the main processing and the like may be distributed by a plurality of electronic devices (for example, a plurality of CPUs). The steps of the main processing and the like can be changed, omitted, and added in order as necessary. The invention also comprises the following modes: an operating system or the like running on the control device 90 performs a part or all of the processing in accordance with instructions from the CPU 91. The following modifications may be added to the main processing and the like as appropriate.

The bonding apparatus 1 may omit setting of the condition combination. In this case, the CPU91 may omit the processing of S11 and S12. When determining that the start instruction is given (S131), the CPU91 may determine whether or not the adhesive Z is liquid before the start of the timing in S132. In this case, it is preferable that the bonding apparatus 1 includes a sensor for detecting the temperature of at least one of the heater 131 and the heater 132, and the CPU91 determines whether or not the adhesive Z is liquid based on the detection result of the sensor. The amount of the nozzle gap interval may be changed in S213. In this case, S202 may be omitted. The start/stop time combination may include changing the nozzle gap interval in S213.
