  The air drive driver 204 is electrically connected to the CPU 200. The air drive driver 204 is electrically connected to the air cylinders 21, 24, 105 and the valve opening / closing cylinder 49. The CPU 200 controls the air pressure sent to the air inlets of the air cylinders 21, 24, 105 and the valve opening / closing cylinder 49 via the air driving driver 204. The first roller 22 moves up and down based on the operation of the air cylinder 21. The support portion 16 moves to the use position and the maintenance position based on the operation of the air cylinder 24. The second pulley 28 moves up and down based on the operation of the air cylinder 105. The valve 55 moves in the vertical direction based on the operation of the valve opening / closing cylinder 49.

  The cloth bonding process will be described with reference to FIGS. 13 is an interrupt process executed when the CPU 200 detects that the operator has depressed the pedal 208, and the flowchart of FIG. 14 shows that the operator has stopped operating the pedal 208. This is an interrupt process that is executed when the error is detected.

  When the process of FIG. 13 is executed, the CPU 200 starts a timer (S1). Note that the timer is updated in other interrupt processing. The CPU 200 determines whether or not the timer value has passed the first predetermined time (S5). The first predetermined time is the time from when the operator depresses the pedal 208 until the cloth is fed, and is 0.1 s from the start of the timer in normal use. When it is determined that the first predetermined time has elapsed (S5: YES), the CPU 200 drives the second motor 92 and the third motor 93 via the motor drive driver 206 to feed the cloth (S10). Thereafter, the process proceeds to S15.

  After the process of S10 or when it is determined that the timer value has not elapsed for the first predetermined time (S5: NO), the CPU 200 determines whether or not the timer value has elapsed for the second predetermined time (S15). The second predetermined time is the time from when the operator depresses the pedal 208 until the gear pump 124 operates, and is 0 s from the start of the timer in normal use. When it is determined that the second predetermined time has elapsed (S15: YES), the CPU 200 drives the first motor 91 via the motor driver 206 to operate the gear pump 124 and supply the adhesive to the nozzle 17. (S20), and then the process proceeds to S25.

  After the process of S20 or when it is determined that the second predetermined time has not elapsed (S15: NO), the CPU 200 determines whether or not the third predetermined time has elapsed (S25). The third predetermined time is the time from when the operator depresses the pedal 208 until the valve 55 is opened, and is 0 s from the start of the timer in normal use. When it is determined that the third predetermined time has elapsed (S25: YES), the CPU 200 drives the valve opening / closing cylinder 49 via the air drive driver 204 to open the valve 55 (S30), and thereafter the processing. The process proceeds to S35.

  After the process of S30, or when it is determined that the timer value has not passed the third predetermined time (S25: NO), the CPU 200 determines whether or not the timer value has passed the fourth predetermined time (S35). The fourth predetermined time is the time from when the operator depresses the pedal 208 until the second pulley 28 is moved, and is 0 s from the start of the timer in normal use. When it is determined that the timer value has passed the fourth predetermined time (S35: YES), the CPU 200 drives the air cylinder 105 via the air drive driver 204 to move the second pulley 28 from the second position to the first position. Move (S40), and then the process proceeds to S5. When determining that the timer value has not elapsed for the fourth predetermined time (S35: NO), the CPU 200 shifts the process to S5.

  When the process of FIG. 14 is executed, the CPU 200 starts a timer (S101). Note that the timer is updated in other interrupt processing. The CPU 200 determines whether or not the timer value has passed the fifth predetermined time (S105). The fifth predetermined time is a time from when the operator stops the operation of the pedal 208 until the cloth feed is stopped, and is 0 s from the start of the timer in normal use. When it is determined that the timer value has passed the fifth predetermined time (S105: YES), the CPU 200 stops the cloth feed by stopping the second motor 92 and the third motor 93 via the motor driver 206 (S110). Thereafter, the process proceeds to S115.

  After the processing of S110, or when it is determined that the timer value has not passed the fifth predetermined time (S105: NO), the CPU 200 determines whether or not the timer value has passed the sixth predetermined time (S115). The sixth predetermined time is the time from when the operator stops operating the pedal 208 until the gear pump 124 is stopped, and is 0.03 s from the start of the timer in normal use. When it is determined that the sixth predetermined time has elapsed (S115: YES), the CPU 200 stops the first motor 91 via the motor drive driver 206, stops the gear pump 124 (S120), and then performs processing. The process proceeds to S125.

  After the processing of S120, or when it is determined that the timer value has not elapsed for the sixth predetermined time (S115: NO), the CPU 200 determines whether the timer value has elapsed for the seventh predetermined time (S125). The seventh predetermined time is the time from when the operator stops operating the pedal 208 until the valve 55 is closed, and is 0.1 s from the start of the timer in normal use. If it is determined that the timer value has passed the seventh predetermined time (S125: YES), the CPU 200 drives the valve opening / closing cylinder 49 via the air drive driver 204 to close the valve 55 (S130). The process proceeds to S135.

  After the process of S130, or when it is determined that the timer value has not passed the seventh predetermined time (S125: NO), the CPU 200 determines whether the timer value has passed the eighth predetermined time (S135). The eighth predetermined time is a time from when the operator stops operating the pedal 208 until the second pulley 28 is moved, and is 0 s from the start of the timer in normal use. When it is determined that the eighth predetermined time has elapsed (S135: YES), the CPU 200 drives the air cylinder 105 via the air drive driver 204 to move the second pulley 28 from the first position to the second position. Move (S140), and then the process proceeds to S105. If the CPU 200 determines that the timer value has not passed the eighth predetermined time (S135: NO), the CPU 200 moves the process to S105.

  As described above, in the cloth bonding apparatus 1 in the first embodiment, the CPU 200 drives the air cylinder 105 to move the second pulley 28 from the first position when the operator stops the operation of the pedal 208. Move to the second position. When the second pulley 28 moves to the second position, the space between the lower cloth 152 and the nozzle 17 is increased. The cloth bonding apparatus 1 removes an adhesive between the lower cloth 152 and the nozzle 17 when the bonding operation is stopped, and adheres to the rear portion of the nozzle 17 and does not contact the cloth (referred to as an adhesive before cloth bonding). The nozzle 17 can be moved to the contact portion with the cloth. Therefore, the cloth bonding apparatus 1 can prevent the adhesive adhering to the rear of the nozzle 17 from adhering to the cloth to form an adhesive reservoir. When the cloth bonding apparatus 1 resumes the bonding work, the amount of adhesive applied to the cloth does not vary.

  When the operator depresses the pedal 208, the CPU 200 drives the air cylinder 105 to move the second pulley 28 from the second position to the first position. As the second pulley 28 moves to the first position, the belt 27 and the nozzle 17 sandwich the lower cloth 152. When the second pulley 28 moves to the second position, the cloth bonding apparatus 1 can start the bonding work by attaching the adhesive moved below the nozzle 17 to the cloth.
