  The guide portion 762 has a surface 764 that supports the lower cloth 8 from below, and guides the lower cloth 8 from the first support portion 58 to the outer periphery of the first roller 761 along the surface 764. The guide portion 762 is provided on the front side of the first roller 761. The guide portion 762 is positioned between the first roller 761 and the first support portion 58 in the transport direction so that the upstream side in the transport direction is lower than the downstream side in the transport direction. The guide portion 762 is separated from the first support portion 58 in the transport direction. The guide portion 762 has a truncated cone shape whose diameter is smaller toward the front side. The surface 764 of the guide portion 762 inclines linearly when viewed from the left side. The front end of the guide portion 762 is chamfered. As shown in FIG. 7, when the lower roller 76 is in the upper position described later, the vertical position of the upper end 765 on the upstream side in the transport direction of the guide portion 762 is lower than the vertical position of the upper surface 581 of the first support portion 58. The position. The vertical position of the upper end 765 at the upstream end in the transport direction of the guide portion 762 is lower than the vertical position of the upper end 766 at the downstream end of the first roller 761 in the transport direction. The vertical lengths of the upper end 767 of the first roller 761 and the upper end 765 at the upstream end of the guide portion 762 in the transport direction are larger than the depth of the groove 763. The vertical position of the upper end of the guide portion 762 on the upstream side in the transport direction may be the same position as the vertical position of the upper surface 581 of the first support portion 58. The guide portion 762 is a rotating member fixed to the shaft portion 75. The guide portion 762 is formed integrally with the first roller 761 and fixed to the shaft portion 75. The guide portion 762 can be moved up and down together with the first roller 761 by a moving mechanism 81 described later. The length D2 of the guide portion 762 in the carrying direction is longer than the length D1 of the groove 763 in the carrying direction. When the lower motor 72 is driven, the shaft portion 75 rotates via the drive shaft of the lower motor 72, the connecting shaft 910, and the belt 74. Therefore, the lower roller 76 rotates around the shaft 75 together with the shaft 75.

  The moving mechanism 81 moves the lower roller 76 to the upper position and the lower position. At this time, the lower transport mechanism 66 does not move. The moving mechanism 81 includes a plate portion 930, an air cylinder 931 and a plate member 933. The plate portion 930 is provided on the upper surface of the fixed base portion 71 and extends in the left-right direction.

The plate member 933 is an L-shaped member in a front view, and is fixed to the right end portion of the output shaft 932. The right end of the plate member 933 contacts the pin 940 of the lower motor 72. When the output shaft 932 advances to the right, the plate member 933 moves the pin 940 to the right. As shown by arrows A and B in FIG. 8, as the pin 940 moves, the lower motor 72 swings counterclockwise from the connecting shaft 910 together with the support frame 73 against the biasing force of the spring 946. . Therefore, as shown by the arrow C in FIG. 8, the shaft portion 75 moves downward, and the lower roller 76 moves to a lower position which is located below. As shown by the chain double-dashed line in FIG. 4, the lower position is the position of the lower roller 76 which is spaced downward from the lower surface 317 of the second support portion 314 described later. When the air cylinder 931 is driven to move the pin 940 to the left, the lower motor 72 swings counterclockwise in a front view together with the support frame 73 by the urging force of the spring 946. Therefore, the first drive unit 80 rotates counterclockwise as viewed from the front with respect to the fixed base unit 71, and the lower roller 76 moves to the upper position. As shown by the dotted line in FIG. 4, the upper position is the position of the lower roller 76 moved upward until it comes into contact with the lower surface 317 of the second support 314 by the urging force of the spring 946.

  As shown in FIGS. 8 and 9, the position detector 950 can output a signal indicating the vertical position of the lower roller 76 to the CPU 101. The position detector 950 includes an extension member 951, a magnetic body 962, and a magnetic sensor 963. The extending member 951 has a plate shape extending in the vertical direction. The extending member 951 rotates together with the lower motor 72. The magnetic body 962 is a permanent magnet fixed to the lower end of the extending member 951. The magnetic body 962 moves in the left-right direction as the extending member 951 rotates. The magnetic sensor 963 is fixed to the support plate 998. The support plate 998 extends downward from the front surface of the fixed base 71 in front of the magnetic body 962. The magnetic sensor 963 can detect the magnetism of the magnetic body 962. The magnetic field detected by the magnetic sensor 963 changes as the position of the magnetic body 962 in the left-right direction changes. Therefore, the magnetic sensor 963 can detect the horizontal position of the magnetic body 962.

  As shown in FIGS. 4 to 6, the lower detection unit 78 is arranged inside the support frame 61 and below the opening 591 provided in the nozzle plate 59. The lower detection unit 78 is an optical detector in which the lower light emitting unit 781 and the lower light receiving unit 782 (see FIG. 10) are integrated. The lower light emitting portion 781 and the lower light receiving portion 782 are at the same height position. The lower light emitting portion 781 emits light toward the opening 591 of the nozzle plate 59. The light that has passed through the opening 591 is reflected by the reflection plate 96 provided on the lower surface 317 of the second support 314. The reflected light reflected by the reflecting plate 96 passes through the opening 591. The lower light receiving unit 782 can receive the light that has passed through the opening 591.

  For example, when the lower specific end 8A of the lower cloth 8 is above the opening 591 of the nozzle plate 59, the lower specific end 8A blocks the light emitted by the lower light emitting unit 781. Therefore, the lower light receiving unit 782 does not receive the light emitted by the lower light emitting unit 781. When the lower specific end portion 8A is not above the opening 591, the light emitted from the lower light emitting portion 781 is reflected by the reflecting plate 96. The lower light receiving unit 782 receives the reflected light through the opening 591. Therefore, the lower detection unit 78 can detect whether or not the lower specific end portion 8A is above the opening 591. The opening 591 of the nozzle plate 59 is provided at the lower detection position where the lower detection unit 78 detects the lower specific end 8A.

  As shown in FIGS. 1 to 4, the head 5 includes an upper transport mechanism 70, a holding mechanism 98, a nozzle swing mechanism 22, and a mounting portion 41. The upper transport mechanism 70 includes a support arm 16, an upper transport roller 12, an upper transport motor 112, a transmission mechanism, an air cylinder 122 (see FIG. 10), and a link mechanism 124. The support arm 16 extends below the head 5 from the rear side to the front side, and further extends to the front lower side. The support arm 16 rotatably supports the upper conveyance roller 12 at the lower front end. The upper carrying roller 12 is a disk-shaped member, and the rotary shaft 121 of the upper carrying roller 12 faces the left-right direction. The upper transport roller 12 is located downstream of the nozzle 11 in the transport direction. The upper carrying roller 12 cooperates with the lower carrying roller 64 to carry the lower cloth 8 and the upper cloth 6 to which the adhesive Z is attached in the carrying direction. The upper conveyance motor 112 is provided on the support arm 16. The upper conveyance motor 112 is connected to the upper conveyance roller 12 via a transmission mechanism provided inside the support arm 16. The transmission mechanism includes, for example, a connecting shaft, a pair of pulleys, and an endless belt, which are not shown. The connecting shaft is connected to the output shaft of the upper conveyance motor 112 and rotates together with the output shaft. One pulley is fixed to the connecting shaft, and the other pulley is fixed to the rotating shaft 121 of the upper conveying roller 12. The endless belt is bridged between a pair of pulleys. Therefore, the upper conveyance roller 12 is rotated by the power of the upper conveyance motor 112.

  The air cylinder 122 is provided on the head 5 in a posture along the carrying direction. The air cylinder 122 includes a shaft 123, and the shaft 123 is connected to the support arm 16 via a link mechanism 124. The support arm 16 swings in the vertical direction by driving the air cylinder 122. When the air cylinder 122 swings the support arm 16, the upper transport roller 12 moves between the holding position and the upper retracted position. In FIG. 4, the upper conveyance roller 12 in the nipping position is shown by a solid line, and the upper conveyance roller 12 in the upper retracted position is shown by a chain double-dashed line. The upper conveyance roller 12 in the nipping position comes into contact with the upper cloth 6 from above and sandwiches the lower cloth 8 and the upper cloth 6 between the lower conveyance rollers 64. The upper carrying roller 12 in the upper retreat position is above the upper cloth 6 and is separated from the upper cloth 6.

  The holding mechanism 98 holds the lower cloth 8 by pressing it from above. The holding mechanism 98 includes air cylinders 974 and 984, holding portions 971 and 981, and a connecting portion 983. The air cylinder 974 is provided upstream of the nozzle 11 in the transport direction with the output shaft 972 facing downward. The holding portion 971 is fixed to the lower end of the output shaft 972. The air cylinder 984 is provided downstream of the nozzle 11 in the transport direction with the output shaft 982 facing downward. The connecting portion 983 connects the lower end of the output shaft 982 and the upper end of the holding portion 981. The bottom surfaces of the holding portions 971 and 981 are substantially parallel to the front-rear direction. When the output shafts 972 and 982 advance downward, the holding portions 971 and 981 are located at the holding position. When the holding portion 971 is in the holding position, the holding portion 971 can approach the first support portion 58 and contact the lower cloth 8 from the upper side. When the holding portion 981 is in the holding position, the holding portion 981 can approach the nozzle plate 59 and contact the lower cloth 8 from above. When the output shafts 972 and 982 retract upward, the holding portions 971 and 981 are located at the release position shown in FIG. 4 and are separated from the lower cloth 8.

  The nozzle swing mechanism 22 includes a nozzle lever 18, a nozzle 11, a nozzle motor 113, a support shaft, and the like, and is a mechanism capable of swinging the nozzle lever 18 around a support shaft extending in the left-right direction by the power of the nozzle motor 113. The nozzle lever 18 movably supports the nozzle 11 between the approach position and the retracted position. The nozzle lever 18 includes a lever member 9 and a cover 181. The lever member 9 has an arm shape extending downward from the left end of the support shaft. The lever member 9 includes a flow passage 21, a nozzle mounting portion 10, and a heater 132 (see FIG. 10) inside. The flow path 21 has a tubular shape extending in the vertical direction. The nozzle mounting portion 10 detachably mounts the nozzle 11. The nozzle mounting portion 10 can attach and detach a plurality of types of nozzles 11 having mutually different widths or positions in the left-right direction of the ejection port 13. The heater 132 is provided inside the lever member 9 near the flow path 21 and heats the adhesive Z flowing in the flow path 21. The cover 181 has a box shape extending in the vertical direction and covers the lever member 9 and the air cylinder 974.

  The nozzle 11 projects downward from the nozzle mounting portion 10 and further projects rightward. The right portion of the nozzle 11 has a rod shape that is a substantially triangular shape when viewed from the left side. The nozzle 11 is mounted on the nozzle mounting portion 10 with a screw. The nozzle 11 has a channel 15 inside. The flow path 15 communicates with the flow path 21 provided in the lever member 9. The upper end of the nozzle 11 supports the upper cloth 6 from below. The discharge port 13 is formed on the lower surface of the nozzle 11. The discharge ports 13 are a plurality of circular holes arranged in the left-right direction at substantially equal intervals. The nozzle motor 113 is a pulse motor provided on the left side inside the head 5. The nozzle motor 113 has an output shaft to which the worm is fixed. The support shaft has a tubular shape extending in the left-right direction above the worm. The support shaft supports a worm wheel that meshes with the upper end of the worm. The support shaft rotates together with the worm wheel by the power of the nozzle motor 113.

  In FIG. 2, the nozzle 11 at the approaching position is shown by a solid line, and the nozzle 11 at the retracted position is shown by a two-dot chain line. When the nozzle 11 is in the approaching position, the discharge port 13 faces downward and faces the lower cloth 8 from above. The bonding apparatus 1 discharges the adhesive Z from the discharge port 13 toward the lower cloth 8 when the nozzle 11 is at the approaching position. When the nozzle 11 is in the retracted position, the discharge port 13 faces downward and forward.

  As shown in FIGS. 1 to 3, the mounting portion 41 mounts the cartridge containing the adhesive Z. The mounting portion 41 is provided substantially at the center of the head 5, and includes a cover 411, a housing portion 412, a lid 413, and a heater 131 (see FIG. 10). The cover 411 has a substantially rectangular parallelepiped box shape and extends upward from the upper surface of the head 5. The cover 411 opens vertically. The housing portion 412 is provided inside the cover 411. The accommodating portion 412 has a substantially rectangular parallelepiped box shape and extends from the inside of the head 5 to the upper end of the cover 411. The accommodating portion 412 opens upward. The accommodating portion 412 accommodates the cartridge in a removable manner. The lid 413 is detachably provided on the upper side of the housing portion 412 and opens and closes the upper opening of the housing portion 412. The cartridge contains a heat-meltable adhesive Z (see FIG. 4). The adhesive Z liquefies when heated to a predetermined temperature and solidifies at a temperature lower than the predetermined temperature. The heater 131 is provided in the housing portion 412. The heater 131 heats the cartridge stored in the storage portion 412. The adhesive Z is melted and liquefied by the heating of the heater 131.

  As shown in FIGS. 1 and 3, the arm portion 4 includes a second drive unit 30, a supply mechanism 45, and an upper detection unit 85. The second drive unit 30 controls the position of the upper cloth 6 in the left-right direction. The second drive unit 30 is provided on the lower surface of the arm 4. The second drive unit 30 includes an upper arm 31, a rotary shaft 33, a second roller 32, an upper motor 38, a transmission mechanism, a spring 37, an air cylinder 39 and the like. The upper arm 31 extends downward and leftward from the right side of the lower surface of the arm 4, and has an arm shape and a tubular shape. The right end of the upper arm 31 is rotatably supported around the axis W on the lower left side of the arm 4. The lower left end of the upper arm 31 is arranged on the upstream side in the transport direction of the nozzle 11 located at the approaching position. The rotary shaft 33 projects rearward from the lower left end of the upper arm 31, and the front-rear direction is the axial direction. The second roller 32 is a disk-shaped member fixed to the rear end of the rotating shaft 33, and can rotate together with the rotating shaft 33 in the front-rear direction as the axial direction. The second roller 32 is arranged above the lower roller 76. The second roller 32 has a plurality of grooves 34 on the outer periphery that extend in the transport direction. The upper motor 38 is a motor that can rotate forward and backward. The transmission mechanism is provided inside the upper arm 31. The transmission mechanism includes, for example, a pair of pulleys (not shown) and an endless belt. One pulley is fixed to the output shaft of the upper motor 38, and the other pulley is fixed to the rotation shaft 33 of the second roller 32. The endless belt is bridged between a pair of pulleys. Therefore, the transmission mechanism can transmit the power of the upper motor 38 to the second roller 32 and rotate the second roller 32 in the forward and reverse directions.

  The upper arm 31 rotates about the axis W between the contact position and the separated position. The contact position is the rotational position of the upper arm 31 where the lower end of the second roller 32 is at the same height position as the upper surface 315 of the second support portion 314 described later. At this time, the second roller 32 is in the upper contact position. The separated position is the pivotal position of the upper arm 31 where the lower end of the second roller 32 is located above the upper surface 315 of the second support 314. At this time, the second roller 32 is in the upper separated position. The spring 37 always biases the upper arm 31 clockwise around the axis W in a front view through other members. Therefore, the spring 37 constantly urges the upper arm 31 in the rotation direction from the contact position to the separated position. The tip end of the upper arm 31 is biased by the weight of the upper arm 31 and the second roller 32 to rotate in the direction toward the contact position. Since the spring 37 urges the upper arm 31 in the rotational direction toward the separated position against the urging force, the excessive force of the upper arm 31 toward the contact position is suppressed. The air cylinder 39 drives the upper arm 31 clockwise around the axis W in a front view to rotate the upper arm 31 from the contact position to the separated position.

  The upper detection unit 85 is an optical detection in which the upper light emitting unit 851 and the upper light receiving unit 852 (see FIG. 10) are integrated. The upper detection unit 85 supports between the upper conveyance roller 12 and the second roller 32. The upper detector 85 supports the upper transport roller 12 at the same height as the rotary shaft 121 or at a height lower than that. The upper light emitting portion 851 and the upper light receiving portion 852 are at the same height position. The upper light emitting portion 851 emits light toward the reflecting plate 95 provided on the upper surface 315 of the second supporting portion 314. The light emitted by the upper light emitting unit 851 is reflected by the reflecting plate 95. The upper light receiving section 852 receives the reflected light reflected by the reflecting plate 95. The reflection plate 95 is provided at an upper detection position where the upper detection unit 85 detects the upper specific end portion 6A. For example, when the upper specific end 6A of the upper cloth 6 is above the reflection plate 95, the upper specific end 6A blocks the light emitted by the upper light emitting unit 851. Therefore, the upper light receiving unit 852 does not receive the light emitted by the upper light emitting unit 851. When the upper specific end portion 6A is not above the reflection plate 95, the light emitted by the upper light emitting unit 851 is reflected by the reflection plate 95. The upper light receiving section 852 receives the reflected light. Therefore, the upper detector 85 can detect whether or not the upper specific end 6A is present on the upper surface 315 of the second support 314.

  The supply mechanism 45 includes a pump motor 114 and a gear pump 46. The output shaft 115 of the pump motor 114 extends leftward from the pump motor 114. The gear pump 46 is provided on the front side of the mounting portion 41 and is connected to the lever member 9. The output shaft 115 is connected to the gear pump 46 via a gear 461. The gear pump 46 sucks the adhesive Z from the cartridge housed in the housing portion 412. The gear pump 46 supplies the sucked adhesive Z to the nozzle 11.

  The flow path of the adhesive Z will be described. The adhesive Z flows through the gear pump 46, the flow passage 21 inside the lever member 9 and the flow passage 15 inside the nozzle 11 to reach the discharge port 13. The lever member 9 includes a heater 132 (see FIG. 10) in the vicinity of the flow path inside. The heat of the heater 132 is transferred to the nozzle 11 via the nozzle mounting portion 10. The heater 132 heats the adhesive Z flowing to the ejection port 13 inside the lever member 9. When the pump motor 114 is driven, the gear pump 46 sucks the adhesive Z from the cartridge housed in the housing portion 412. The adhesive Z melted by heating by the heaters 131 and 132 flows from the cartridge through each flow path, and the ejection port 13 ejects the adhesive Z downward.

  The electrical configuration of the bonding apparatus 1 will be described with reference to FIG. The bonding device 1 includes a control device 100. The control device 100 includes a CPU 101, a ROM 102, a RAM 103, a storage device 104, and drive circuits 105 and 106. The CPU 101 integrally controls the operation of the bonding device 1. The CPU 101 is connected to the ROM 102, the RAM 103, the storage device 104, the operation unit 19, the tread 7, the lower detection unit 78, the upper detection unit 85, the drive circuits 105 and 106, the heaters 131 and 132, and the magnetic sensor 963. The ROM 102 stores programs that execute various processes. The RAM 103 temporarily stores various information. The storage device 104 is non-volatile and stores various setting values and the like.

  The operation unit 19 includes a switch, a knee switch, an information input unit, and the like. The switch is provided on the lower part of the front surface of the head 5. The knee switch is installed at the bottom of the workbench and operated by the operator's knee. The information input unit has a liquid crystal screen and can input various information. The information input section is provided on the workbench. The operator operates the operation unit 19 to input various instructions to the bonding apparatus 1. The operation unit 19 outputs information indicating various instructions as a detection result to the CPU 101. The tread 7 is provided at the bottom of the workbench and operated by the operator's foot. The operator inputs a bonding start instruction or an end instruction, which will be described later, through the tread 7. The tread 7 outputs, to the CPU 101, information indicating a bonding start instruction or an adhesion instruction as a detection result. The lower detection unit 78 and the upper detection unit 85 output the detection results to the CPU 101.

  The CPU 101 sends a control signal to the drive circuit 105 to drive and control the lower conveyance motor 63, the upper conveyance motor 112, the nozzle motor 113, the pump motor 114, the gap adjusting motor 68, the lower motor 72, and the upper motor 38. . The CPU 101 sends a control signal to the drive circuit 106 to drive and control each of the air cylinders 39, 122, 931, 974, and 984. The CPU 101 drives the heaters 131 and 132. The heater 131 heats the adhesive Z in the cartridge. The heater 132 heats the adhesive agent Z flowing through the flow path 21 inside the lever member 9 toward the discharge port 13. The adhesive Z is liquefied by heating the heaters 131 and 132. The CPU 101 can detect the vertical position of the lower roller 76 based on the detection result of the magnetic sensor 963.

  Main processing will be described with reference to FIGS. 11 to 13. For example, the operator inputs a main processing start instruction to the operation unit 19. The CPU 101 reads the program from the ROM 102 and starts the main processing. Before the start of the main processing, the bonding device 1 is in the initial state. When the bonding device 1 is in the initial state, the nozzle 11 is in the approaching position, the upper conveying roller 12 is in the nipping position, the second roller 32 is in the upper contact position, and the lower roller 76 is in the upper position. As shown in FIG. 5, an example will be described in which one end side of the cloth 200 is the upper cloth 6 and the other end side is the lower cloth 8, and the cloth 200 is bonded in a tubular state. The cloth 200 has a step portion 203 extending in a direction perpendicular to the transport direction. The step portion 203 is a portion where two pieces of cloth are vertically stacked and adhered.

  The CPU 101 performs initialization processing (S10). In the initialization process, the CPU 101 drives the heaters 131 and 132. The CPU 101 determines whether or not a roller movement instruction has been detected (S11). The roller movement instruction is an instruction to move the upper conveyance roller 12, the second roller 32, and the lower roller 76, respectively. The CPU 101 waits until it detects a roller movement instruction due to the detection result of the operation unit 19 (S11: NO). When the CPU 101 detects the roller movement instruction (S11: YES), the CPU 101 drives and controls the air cylinder 122 to raise the upper conveyance roller 12 (S14). The upper transport roller 12 moves up from the holding position to the upper retracted position.

  The CPU 101 drives and controls the air cylinder 931 to lower the lower roller 76 and move the lower roller 76 from the upper position to the lower position (S15). At this time, the lower roller 76 is separated downward from the lower surface 317 of the second support 314. The CPU 101 drives and controls the air cylinder 39 to raise the second roller 32 and move the second roller 32 from the upper contact position to the upper separated position (S16). The second roller 32 is separated upward from the upper surface 315 of the second support 314.

  The CPU 101 determines whether or not the nozzle displacement instruction is detected based on the detection result of the operation unit 19 (S17). The nozzle displacement instruction is an instruction to displace the nozzle 11 between the approach position and the retracted position. The CPU 101 waits until the nozzle displacement instruction is detected (S17: NO). The operator rotates the second support portion 314 counterclockwise in plan view, moves from the operating position to the retracted position, and then inputs a nozzle displacement instruction using the operation unit 19. When the nozzle displacement instruction is detected (S17: YES), the CPU 101 drives and controls the nozzle motor 113 to swing the nozzle lever 18, and displaces the nozzle 11 from the approach position to the retracted position (S18). The CPU 101 inputs a predetermined pulse signal as a control signal to the drive circuit 105, whereby the nozzle 11 is displaced to the retracted position. Since the second support portion 314 is at the retracted position, the nozzle 11 is displaced to the retracted position without contacting the second support portion 314. Since the nozzle lever 18 includes the holding portion 971, the holding portion 971 moves as the nozzle lever 18 moves. When the nozzle 11 reaches the retracted position, the driving of the nozzle motor 113 is stopped.

  The CPU 101 determines whether or not the nozzle displacement instruction is detected based on the detection result of the operation unit 19 (S19). The CPU 101 waits until the nozzle displacement instruction is detected (S19: NO). After placing the lower cloth 8 on the nozzle plate 59 and the first support portion 58, the operator inputs a nozzle displacement instruction through the operation portion 19. Both the lower transport roller 64 and the nozzle lower roller 65 come into contact with the lower cloth 8 from below. When detecting the nozzle displacement instruction (S19: YES), the CPU 101 drives and controls the nozzle motor 113 to displace the nozzle 11 from the retracted position to the approach position (S20). When the CPU 101 inputs a predetermined pulse signal as a control signal to the drive circuit 105, the nozzle 11 is displaced to the approach position. The discharge port 13 faces the lower cloth 8 from above.

  The CPU 101 executes vertical position adjustment processing (S21). The vertical position adjustment process is a process of adjusting the vertical position of the nozzle plate 59. The operator adjusts the vertical position of the nozzle plate 59 when adjusting the gap K. For example, the operator inputs an instruction to raise or lower the nozzle plate 59 into the operation unit 19. The CPU 101 drives and controls the gap adjusting motor 68 according to the detection result of the operation unit 19 to swing the support frame 61 and move the nozzle plate 59 up and down. The operator operates the operation unit 19 so that an appropriate gap K is created between the lower cloth 8 and the discharge port 13. At this time, the second support portion 314 is in the retracted position (lower part in FIG. 5), and the upper cloth 6 is not placed on the nozzle plate 59 and the first support portion 58. Therefore, the operator can easily visually recognize the vertical distance between the nozzle plate 59 and the discharge port 13. When the operator inputs an end instruction of the adjustment process to the operation unit 19, the CPU 101 detects the end instruction and moves the process to S22.

  The CPU 101 determines whether or not the roller movement instruction is detected based on the detection result of the operation unit 19 (S22). When the roller movement instruction is not detected (S22: NO), the CPU 101 determines whether or not the holding portion movement instruction is detected (S23). The holding unit movement instruction is an instruction for the CPU 101 to control movement of the holding units 971 and 981. When the CPU 101 detects a holding unit movement instruction (S23: YES), the CPU 101 drives and controls the air cylinders 974 and 984 and controls the movement of the holding units 971 and 981 from the release position to the holding position (S24). The holding portions 971 and 981 descend and hold the lower cloth 8 between the first supporting portion 58 and the nozzle plate 59 of the extending portion 552. When the CPU 101 does not detect the holding unit movement instruction (S23: NO) or after S24, the process returns to S22.

  The worker rotates the second support portion 314 clockwise in plan view and moves from the retracted position to the working position (upper in FIG. 5). The second support portion 314 moves to a position above the lower roller 76 and below the second roller 32. The operator places the upper cloth 6 on the upper surfaces 315 of the nozzle plate 59, the first support portion 58, and the second support portion 314. For example, the cloth 200 is arranged in a tubular shape around the extending portion 552. The upper cloth 6 overlaps the lower cloth 8 from the upper side between the lower carrying roller 64 and the upper carrying roller 12. At this time, the upper specific end portion 6A overlaps the lower specific end portion 8A. After placing the top cloth 6, the operator inputs a roller movement instruction to the operation unit 19. When the CPU 101 detects the roller movement instruction (S22: YES), the CPU 101 drives and controls the air cylinder 122 to lower the upper conveyance roller 12 to the nipping position (S25). The upper carrying roller 12 sandwiches the lower cloth 8 and the upper cloth 6 between the lower carrying roller 64.

  The CPU 101 drives and controls the air cylinder 931 to raise the lower roller 76 (S26). When the air cylinder 931 moves the output shaft 932 to the left, the support frame portion 73 rotates clockwise in rear view by the biasing force of the spring 946, and the shaft portion 75 and the lower roller 76 rise. Therefore, the lower roller 76 moves from the lower position to the upper position. At this time, the lower roller 76 sandwiches the lower cloth 8 with the lower surface 317 of the second supporting portion 314.

  The CPU 101 drives and controls the air cylinder 39 to lower the second roller 32 (S27). The second roller 32 moves from the upper separated position to the upper contact position. The second roller 32 sandwiches the upper cloth 6 with the upper surface 315 of the second support portion 314. The CPU 101 executes a bonding process (S28).

  The bonding process will be described with reference to FIG. The bonding process is a process for bonding the lower specific end portion 8A of the lower cloth 8 and the upper specific end portion 6A of the upper cloth 6 with the adhesive Z. The CPU 101 determines whether or not the start instruction is detected depending on whether or not the operator operates the tread 7 with his / her foot (S51). The start instruction is an instruction to start the bonding operation. The start instruction also includes an instruction to move the holding portions 971 and 981 in the holding position to the release position. The CPU 101 waits until the start instruction is detected (S51: NO).

  When the CPU 101 detects the start instruction (S51: YES), the CPU 101 determines whether the holding units 971 and 981 are at the holding position (S52). When the holders 971 and 981 are in the release position (S52: NO), the process proceeds to S54. When the holding portions 971 and 981 are in the holding position (S52: YES), the CPU 101 drives and controls the air cylinders 974 and 984 and controls the movement of the holding portions 971 and 981 from the holding position to the release position (S53). The holding portions 971 and 981 are lifted to release the holding of the lower cloth 8.

  The CPU 101 drives and controls the upper transport motor 112 and the lower transport motor 63 to start driving the upper transport roller 12 and the lower transport roller 64, respectively (S54). The upper carrying roller 12 and the lower carrying roller 64 cooperate to carry the lower cloth 8 and the upper cloth 6 to the rear side. The nozzle lower roller 65 rotates together with the lower conveyance roller 64, and conveys the lower cloth 8 to the rear side auxiliary. The lower cloth 8 contacts the lower conveying roller 64 and the nozzle lower roller 65, and moves in the conveying direction. The surface 764 of the guide portion 762 guides the lower cloth 8 of the upper surface 581 of the first support portion 58 to the upper end 767 of the first roller 761. The lower cloth 8 smoothly moves from the upper surface 581 of the first support portion 58 to the upper end 767 of the first roller 761.

  The CPU 101 drives and controls the pump motor 114 to start discharging the adhesive Z (S55). The adhesive Z is liquefied by the heat generated by the heaters 131 and 132. The supply mechanism 45 supplies the adhesive Z to the nozzle 11 by driving the pump motor 114. The ejection port 13 (see FIG. 7) ejects the adhesive Z toward the lower specific end portion 8A located below. While the ejection port 13 applies the adhesive Z to the lower specific end portion 8A, the upper conveyance roller 12, the lower conveyance roller 64, and the nozzle lower roller 65 convey the lower cloth 8 and the upper cloth 6 to the rear side.

  The CPU 101 determines whether the lower specific end portion 8A is at the lower detection position based on the detection result of the lower detection unit 78 (S56). When the light receiving unit of the lower detection unit 78 does not receive light, the CPU 101 determines that the lower specific end portion 8A is at the lower detection position (S56: YES). At this time, the CPU 101 drives and controls the lower motor 72 to rotationally drive the lower roller 76 in the first output direction (S57). The first output direction is a rotation direction in which the upper end of the lower roller 76 is directed to the left. The lower roller 76 rotating in the first output direction moves the lower specific end portion 8A to the left. At this time, the lower specific end portion 8A moves in a direction away from the lower detection position.

  When the light receiving unit of the lower detection unit 78 receives light, the CPU 101 determines that the lower specific end portion 8A is not at the lower detection position (S56: NO). The CPU 101 drives and controls the lower motor 72 to rotate the lower roller 76 in the second output direction (S58). The second output direction is opposite to the first output direction. The lower roller 76 rotating in the second output direction moves the lower specific end portion 8A to the right. At this time, the lower specific end portion 8A moves in a direction approaching the lower detection position.

  After S57 and S58, the CPU 101 determines whether the upper specific end 6A is at the upper detection position based on the detection result of the upper detection unit 85 (S59). When the light receiving unit of the upper detection unit 85 does not receive light, the CPU 101 determines that the upper specific end 6A is at the upper detection position (S59: YES). The CPU 101 drives and controls the upper motor 38 to rotationally drive the second roller 32 in the third output direction (S60). The third output direction is a rotation direction in which the lower end of the second roller 32 is directed to the right. The second roller 32 rotating in the third output direction moves the upper specific end 6A to the right. At this time, the upper specific end 6A moves in a direction away from the upper detection position.

  When the light receiving unit of the upper detection unit 85 does not receive light, the CPU 101 determines that the upper specific end portion 6A is not at the upper detection position (S59: NO). The CPU 101 drives and controls the upper motor 38 to rotationally drive the second roller 32 in the fourth output direction (S61). The fourth output direction is opposite to the third output direction. The second roller 32 rotating in the fourth output direction moves the upper specific end 6A to the left. At this time, the upper specific end 6A moves in a direction approaching the upper detection position.

  After S60 and S61, the CPU 101 executes a gap adjusting process (S62). The gap adjusting process is a process of adjusting the gap K according to the vertical position of the lower roller 76. As shown in FIG. 13, in the gap adjusting process, the CPU 101 determines whether or not the lower roller 76 has descended due to the detection result of the magnetic sensor 963 (S101). While the portion of the lower cloth 8 that is not the step portion 203 or the step portion 203 of the lower cloth 8 passes between the lower roller 76 and the lower surface 317 of the second support portion 314, the lower roller 76 does not descend. Rotate in the first output direction or the second output direction. At this time, the extending member 951 does not move in the left-right direction, and the detection result of the magnetic sensor 963 becomes constant. Therefore, the CPU 101 determines that the lower roller 76 has not descended (S101: NO), and moves the process to S109. The CPU 101 refers to the storage device 104 and determines whether or not the descending flag is ON (S109). The descending flag is stored in the storage device 104. The initial value of the descending flag is OFF. When the descending flag is OFF (S109: NO), the CPU 101 shifts the processing to S201.

  As shown in FIG. 4, when the lower rear end portion 202 of the stepped portion 203 of the lower cloth 8 enters between the lower roller 76 and the lower surface 317 of the second support portion 314, the change in the thickness of the lower cloth 8 is changed. The lower portion of the stepped portion is pushed downward by the amount (hereinafter referred to as the height of the stepped portion) of the stepped portion. The shaft portion 75 rotates clockwise around the connecting shaft 910 in a front view. Therefore, the extending member 951 rotates clockwise around the connecting shaft 910 in a front view, and the magnetic body 962 moves leftward. The magnetic sensor 963 detects the leftward movement of the magnetic body 962, and also detects the horizontal position after the movement. At this time, the CPU 101 determines that the lower roller 76 has descended (S101: YES). The descending amount of the lower roller 76 is acquired based on the detection result of the magnetic sensor 963 (S103). When S101 is executed, the magnetic sensor 963 outputs the left-right position of the magnetic body 962 before and after the movement to the CPU 101 as a detection result. The CPU 101 acquires the lateral movement amount of the magnetic body 962 based on the detection result of the magnetic sensor 963, and acquires the lowering amount of the lower roller 76 based on the acquired movement amount (S103).

  The CPU 101 starts timing (S105). The CPU 101 sequentially stores the time measurement result in the RAM 103. The CPU 101 updates the descending flag stored in the storage device 104 to ON (S107). The CPU 101 determines whether or not a predetermined time has elapsed after starting the time counting in S105 (S111). The predetermined time is set to the timing when the lower rear end portion 202 enters between the nozzle 11 and the nozzle lower roller 65 due to the conveyance speed of the lower cloth 8. When the rear end of the stepped portion is between the nozzle 11 and the nozzle lower roller 65, the predetermined time has not elapsed (S111: NO). At this time, the CPU 101 shifts the processing to S201.

  When the predetermined time has elapsed (S111: YES), the CPU 101 drives and controls the gap adjusting motor 68, and lowers the support frame 61 by the lowering amount of the lower roller 76 acquired in S103 (S113). In particular, the gap K between the discharge port 13 of the nozzle 11 and the nozzle plate 59 is wider than before the movement. The support frame 61 ends the downward movement at the timing when the lower rear end 202 enters between the nozzle lower roller 65 and the nozzle 11. Therefore, before and after the lower rear end portion 202 enters between the nozzle lower roller 65 and the nozzle 11, the bonding apparatus 1 can keep the discharge distance constant. The discharge distance is the shortest distance between the discharge port 13 of the nozzle 11 and the lower cloth 8. The CPU 101 ends the time measurement (S115), updates the descending flag stored in the storage device 104 to OFF (S119), and shifts the processing to S201.

  The CPU 101 determines whether or not the lower roller 76 has risen due to the detection result of the magnetic sensor 963 (S201). While the portion of the lower cloth 8 that is not the step portion 203 or the step portion 203 of the lower cloth 8 passes between the lower roller 76 and the lower surface 317 of the second support portion 314, the lower roller 76 does not rise, Rotate in the first output direction or the second output direction. At this time, the extending member 951 does not move in the left-right direction, and the detection result of the magnetic sensor 963 becomes constant. Therefore, the CPU 101 determines that the lower roller 76 has not moved up (S201: NO), and moves the process to S209. The CPU 101 refers to the storage device 104 and determines whether the rising flag is ON (S209). The rising flag is stored in the storage device 104. The initial value of the rising flag is OFF. When the rising flag is OFF (S209: NO), the CPU 101 ends the gap adjusting process and returns the process to the adhering process of FIG.

  As shown in FIG. 14, when the upper front end 201 of the stepped portion 203 of the lower cloth 8 passes between the lower roller 76 and the lower surface 317 of the second support 314, the lower roller 76 is urged by the spring 946. Move up by the height of the step. The shaft portion 75 rotates counterclockwise in a front view about the connecting shaft 910. Therefore, the extending member 951 rotates counterclockwise in front view about the connecting shaft 910, and the magnetic body 962 moves to the right. The magnetic sensor 963 detects the rightward movement of the magnetic body 962, and also detects the lateral position after the movement. At this time, the CPU 101 determines that the lower roller 76 has risen (S201: YES), and acquires the amount by which the lower roller 76 has risen based on the detection result of the magnetic sensor 963 (S203). The magnetic sensor 963 outputs the left-right position of the magnetic body 962 before and after the movement to the CPU 101 as a detection result. The CPU 101 obtains the lateral movement amount of the magnetic body 962 due to the detection result of the magnetic sensor 963, and the elevation amount of the lower roller 76 due to the obtained movement amount (S203).

  The CPU 101 starts clocking (S205). The CPU 101 sequentially stores the time measurement result in the RAM 103. The CPU 101 updates the rising flag stored in the storage device 104 to ON (S207). The CPU 101 determines whether or not a predetermined time has elapsed after starting the time counting in S205 (S211). The predetermined time of S211 is set similarly to S111. When the predetermined time has not elapsed (S211: NO), the CPU 101 ends the rising process and returns the process to the bonding process of FIG.

  When the predetermined time has elapsed (S211: YES), the CPU 101 drives and controls the gap adjusting motor 68, and raises the support frame 61 by the amount of rise of the lower roller 76 acquired in S203 (S213). In particular, the gap K between the discharge port 13 of the nozzle 11 and the nozzle plate 59 becomes narrower than before the movement. At the timing when the upper front end portion 201 passes between the nozzle lower roller 65 and the nozzle 11, the support frame 61 ends the upward movement. Therefore, before and after the upper front end portion 201 passes between the nozzle lower roller 65 and the nozzle 11, the bonding apparatus 1 can keep the ejection distance constant. The CPU 101 ends the time measurement (S215), updates the rising flag stored in the storage device 104 to OFF (S219), ends the gap adjusting process, and returns the process to the bonding process of FIG. The CPU 101 determines whether or not an instruction to end the bonding process is detected based on the detection result of the tread 7 (S63). When the CPU 101 does not detect an instruction to end the bonding process (S63: NO), the process returns to S56. When the CPU 101 detects an instruction to end the bonding process (S63: YES), the CPU 101 stops driving the upper conveyance motor 112, the lower conveyance motor 63, the pump motor 114, the lower motor 72, and the upper motor 38 (S68). The CPU 101 ends the adhesion process and ends the main process.

  In the above embodiment, the bonding device 1, the discharge port 13, the nozzle 11, and the supply mechanism 45 are examples of the bonding device, the discharge port, the nozzle, and the supply unit of the present invention. The upper transport mechanism 70 and the lower transport mechanism 66 are examples of the transport unit of the present invention.

The discharge port 13, the nozzle 11, and the supply mechanism 45 are examples of the discharge port, the nozzle, and the supply unit of the present invention. The CPU 101 that executes S54 and S55 is an example of the ejection / transport control unit of the present invention.

The CPU 101 that executes S57 and S58 is an example of the first movement control unit of the present invention. The first support portion 58, the surface 764, and the guide portion 762 are examples of the first support portion, surface, and guide portion of the present invention.

The CPU 101 that executes the processing of S60 and S61 is an example of the second movement control unit of the present invention. The moving mechanism 81 is an example of the moving unit of the present invention. The CPU 101 that executes S62 is an example of the adjustment control unit of the present invention.

  Even if the lower cloth 8 has a step portion, the adhesive device 1 of the above-described embodiment can guide the lower cloth 8 from the first support portion 58 to the outer periphery of the lower roller 76 by the guide portion 762. The bonding apparatus 1 can prevent the application state of the adhesive Z from being varied and the adhesive quality from being deteriorated due to the side surface of the lower roller 76 restricting the movement of the stepped portion.

  The bonding device 1 includes a second support part 314, a second roller 32, and a second drive part 30. The second support portion 314 faces the first roller 761 from above and can sandwich the lower cloth 8 with the first roller 761. The second driving unit 30 of the second roller 32 is disposed between the nozzle 11 and the first support unit 58 in the transport direction, and the outer periphery of the second roller 32 contacts the upper fabric 6 from above, and the second drive unit 30 and the second support unit 314 form the upper fabric. 6 can be pinched, and the upper cloth 6 is moved in a specific direction. The second driving unit 30 is connected to the second roller 32. The CPU 101 controls the second drive unit 30 to rotate the second roller 32 and move the upper cloth 6 in a specific direction (S60, S61). The bonding apparatus 1 includes a moving mechanism 81 that supports the first roller 761 so as to be vertically movable. The bonding device 1 has a nozzle plate 59 and a gap adjusting portion 77 capable of changing the vertical position of the nozzle plate 59. The nozzle plate 59 supports the lower cloth 8 from below under the nozzle 11, and is provided on the downstream side of the first support portion 58 in the transport direction. The CPU 101 changes the vertical position of the nozzle plate 59 by controlling the gap adjusting unit 77 according to the vertical position of the lower roller 76 (S62). The guide portion 762 is provided so as to be vertically movable together with the first roller 761. Therefore, the adhering device 1 changes the vertical position of the nozzle plate 59 according to the vertical position of the first roller 761 so that the lower cloth 8 and the discharge port 13 of the nozzle 11 can be connected even if the lower cloth 8 has a step. The gap can be adjusted appropriately. The bonding device 1 can appropriately adjust the position of the end portion of the upper cloth 6 with respect to the end portion of the lower cloth 8 by the first roller 761 and the second roller 32.

  Specifically, when the step portion of the lower cloth 8 enters between the lower roller 76 and the lower surface 317 of the second support portion 314, the lower roller 76 moves downward against the biasing force of the spring 946. At this time, the magnetic body 962 moves to the left, and the output voltage which is the detection result of the magnetic sensor 963 changes (S101: YES). At this time, the CPU 101 lowers the support frame 61 by the height of the step due to the detection result of the magnetic sensor 963 (S113). When the step portion passes between the lower roller 76 and the lower surface 317 of the second support portion 314, the lower roller 76 moves upward by the biasing force of the spring 946. At this time, the magnetic body 962 moves to the right and the output voltage of the magnetic sensor 963 changes (S201: YES). The CPU 101 raises the support frame 61 at the timing when the stepped portion passes between the nozzle lower roller 65 and the nozzle 11 due to the detection result of the magnetic sensor 963 (S213). Therefore, the bonding device 1 can adjust the discharge distance according to the thickness of the lower cloth 8 that passes through the second support portion 314 and the lower roller 76. Therefore, the bonding device 1 can suppress the deterioration of the working efficiency when bonding the lower cloth 8 having the stepped portion, and at the same time, can suppress the bonding failure due to the change in the ejection distance.

  The magnetic sensor 963 detects the lateral position of the magnetic body 962. That is, the magnetic sensor 963 detects the rotational position of the extension member 951. The rotational position of the extending member 951 correlates with the vertical position of the lower roller 76. The adhesive device 1 can arrange the magnetic sensor 963 at a position vertically separated from the lower cloth 8 as compared with the case where the upper and lower positions of the lower roller 76 are directly detected by an optical sensor or a limit switch. Therefore, the bonding apparatus 1 can easily secure the transport area for the lower cloth 8.

  The first drive unit 80 of the bonding apparatus 1 has a shaft portion 75 that extends in the transport direction and fixes the first roller 761. The CPU 101 controls the first drive unit 80 to rotate the shaft portion 75 and rotate the first roller. The guide portion 762 is a rotating member that rotates the 761 and is fixed to the shaft portion 75. Therefore, the guide portion 762 of the bonding apparatus 1 can rotate coaxially with the first roller 761 due to the relatively simple structure.

  The guide portion 762 of the bonding device 1 is a member integrally formed with the first roller 761. Therefore, the bonding apparatus 1 can reduce the number of parts as compared with the case where the guide portion 762 is separate from the first roller 761. The bonding device 1 can reliably prevent the lower cloth 8 from being sandwiched between the guide portion 762 and the first roller 761.

  The vertical position of the end of the guide portion 762 of the bonding apparatus 1 on the upstream side in the transport direction is lower than the vertical position of the upper surface 581 of the first support portion 58 or the vertical position of the upper surface 581 of the first support portion 58. It is the same position as. In the bonding device 1, the lower cloth 8 is unlikely to be caught on the upstream end of the guide portion 762 in the transport direction.

  The first roller 761 of the bonding device 1 has a groove 763 extending in parallel with the transport direction on the outer circumference, and the length D2 of the guide portion 762 in the transport direction is longer than the length D1 of the groove 763 in the transport direction. The bonding device 1 smoothly transfers the lower cloth 8 from the first support part 58 to the outer circumference 769 of the first roller 761 as compared with a device in which the length of the guide portion 762 in the transport direction is equal to or less than the length D1 of the groove 763 in the transport direction. I can guide you.

  The present invention can be modified in various ways other than the above embodiment. The bonding device may be a bonding device that bonds sheets made of a material other than cloth. The shape and structure of the lower conveyance device may be different from those in the above-described embodiment. For example, instead of the cylindrical lower conveyance device 50 having an elongated tubular tip, the lower conveyance device 50 extends horizontally and the lower cloth 8 is pushed from below. A supporting plate member may be provided. The lower transport device may not be removable.

  The shapes of the first roller and the guide portion may be appropriately changed. The first roller and the guide portion may be separate bodies. For example, the bonding device may include the first drive unit 82 shown in FIG. The first drive unit 82 differs from the first drive unit 80 of the above-described embodiment in that it includes a first roller 91 and a guide unit 92 instead of the lower roller 76. The first roller 91 is a disk-shaped member and is fixed to the rear end of the shaft portion 75. The first roller 91 has a plurality of grooves 912 on the outer circumference 911 that extend in the transport direction. The guide part 92 is provided between the first roller 91 and the first support part 58 in the carrying direction, and has a surface 921 whose upstream side in the carrying direction is located below the downstream side in the carrying direction. The guide portion 92 is a truncated cone-shaped member and is a member separate from the first roller 91. The guide portion 92 is separated from the first roller 91 on the upstream side in the transport direction of the first roller 91 and is fixed to the shaft portion 75. The guide portion 92 may contact the first roller 91. The vertical position of the upper end 922 of the guide portion 92 on the upstream side in the transport direction is lower than the vertical position of the upper surface 581 of the first support portion 58. The vertical position of the upper end 922 of the upstream end of the guide portion 92 in the transport direction is lower than the vertical position of the upper end 913 of the downstream end of the first roller 91 in the transport direction. The vertical position of the upper end 923 at the downstream end in the transport direction of the guide portion 92 is the same as the vertical position of the upper end 913 at the downstream end of the first roller 91 in the transport direction. The vertical lengths of the upper end 914 of the first roller 91 and the upper end 922 of the upstream end of the guide portion 92 in the transport direction are larger than the depth of the groove 912. When the moving mechanism 81 is driven, the guide portion 92 moves up and down together with the first roller 91. The length D4 of the plate member 94 in the carrying direction is longer than the length D3 of the groove 912 in the carrying direction.

  The configuration of the guide unit may be appropriately changed, and for example, the guide unit may not be fixed to the shaft unit that fixes the first roller, or may not be a rotating body that rotates with the first roller. For example, the bonding device may include the first driving unit 83 shown in FIG. The first drive unit 83 differs from the first drive unit 80 of the above-described embodiment in that it includes a first roller 91 and a plate member 94 instead of the lower roller 76. The first roller 91 is similar to the first drive unit 82 in FIG. The plate member 94 is a plate-like member provided on the upstream side of the first roller 91 in the transport direction and extending in the transport direction. The plate member 94 includes a plate portion 941 and a guide portion 942. The plate portion 941 is a plate-shaped portion that extends substantially parallel to the shaft portion 75. The front end of the plate portion 941 is fixed to the rear upper end of the support frame portion 73. The guide portion 942 is connected to the rear end of the plate portion 941. The guide portion 942 is provided between the first roller 91 and the first support portion 58 in the transport direction, and the upstream side in the transport direction is located below the downstream side in the transport direction. The guide portion 942 is linearly inclined upward toward the rear side with respect to the extending direction of the plate portion 941. The length D5 of the guide portion 942 in the carrying direction is longer than the length D3 of the groove 912 in the carrying direction. When the first roller 91 rotates, the plate member 94 does not rotate. When the moving mechanism 81 is driven, the plate member 94 moves up and down together with the first roller 91.

  The first roller and the second roller do not have to have grooves on the outer circumference. The length of the guide portion in the transport direction may be the same as or shorter than the length of the groove in the transport direction. The shape of the guide portion may be changed as appropriate, and for example, the shape in side view may have a curved surface. The first roller and the second roller may be provided with a groove portion extending in a direction intersecting the transport direction, a protrusion protruding from the outer peripheral surface, and the like on the outer circumference. The vertical position of the upstream end of the guide portion in the transport direction may be higher than the vertical position of the upper surface of the first support portion. The bonding device may omit the second roller and the second driving unit. At that time, the processes of S16, S27, and S59 to S61 may be appropriately changed. The moving mechanism 81 and the position detector 950 may be omitted as appropriate. At that time, the process of S62 may be appropriately omitted. The magnetic sensor 963 may be an optical sensor or another detector such as a limit switch.

  The second drive unit 30 may be omitted. At this time, the moving mechanism 81 may be omitted, and the lower roller 76 may not move to the upper position and the lower position. For example, a holding member that can hold the lower cloth 8 with the lower roller 76 and that can move up and down may be provided, and a position detection unit that can output a signal indicating the vertical position of the holding member to the CPU 101 may be provided.

  Each process in the gap adjusting process may be appropriately changed. For example, in the process of S113, the descending amount of descending the support frame 61 by the drive control of the gap adjusting motor 68 may be a preset amount instead of the descending amount of the lower roller 76 acquired in S103. At this time, the process of S103 may be omitted. In the process of S213, the amount by which the support frame 61 is raised by the drive control of the gap adjusting motor 68 may be a preset amount instead of the amount of the lower roller 76 obtained in S203. At this time, the process of S203 may be omitted.

  The program including the command for the bonding device to execute the main process may be stored in the storage device of the bonding device before the bonding device executes the main process. Each of the acquisition method of the program, the acquisition route, and the device storing the program may be appropriately changed. The adhesive device may receive the program executed by the control unit from another device via a cable or wireless communication and store the program in a storage device such as a flash memory. Other devices include, for example, a PC and a server connected via a network. Each step of the processing executed by the bonding apparatus is not limited to the example executed by the CPU 101, and another electronic device (for example, ASIC) may execute a part or all of the processing. A plurality of electronic devices (for example, a plurality of CPUs) may perform distributed processing in each step of the above processing. The order of each step of the main processing of the above-described embodiment can be changed, and steps can be omitted or added as necessary. According to the present invention, an operating system (OS) or the like running on the bonding apparatus performs a part or all of actual processing in response to a command from the control unit of the bonding apparatus, and the functions of the above-described embodiment are realized by the processing. Aspect is also included.
