In this printing apparatus, the nozzle head 1 travels in the width direction of the fabric 10 every time the fabric 10 is intermittently fed.
The number of running times is proportional to the feed amount of the fabric 10. Therefore, the feed amount of the fabric 10 is measured by the number of times of running n. Furthermore, when the other detection device 24b detects the seam 18 of the cloth 10 before the number of times of running n exceeds the set value N, the controller 25 thereafter counts the number of times of running of the nozzle head 1 and the cloth 1
When the feed amount of 0 is measured, and the number of times of traveling reaches the set value F as shown in FIG. 3C, the print unit 2 is controlled by the control device 25, and the nozzle head 1 is stationary at its standby position and is not driven. .. At the same time, the drive motor 8 is controlled by the control device 25, and the fabric 10 is continuously fed by the endless belt 3 and is idly fed. While the fabric 10 is being fed, the nozzle head 1 does not run, and the fabric 10 is not printed. In addition, as shown in FIG. 3D, after the fabric 10 is started to be fed by idle, the feed amount is measured by the control device 25, and when it reaches the set value G, the feed state is released by the control device 25, and the fabric 10 is released. Is again intermittently fed, the nozzle head 1 runs again, and the fabric 10 is printed again.

Until the number of running times n of the nozzle head 1 exceeds the set value N, the number of running times of the nozzle head 1 reaches the set value F.
The seam 18 does not reach the position 19 of the nozzle head 1. Therefore, before the seam 18 of the cloth 19 reaches the position 19 of the nozzle head 1, the cloth 1 is sewn by the endless belt 3.
0 is sent in the air. Further, even if the seam 18 of the cloth 10 is hardly skewed and the seams 18 of the cloth 10 are simultaneously detected by the detection devices 24a and 24b, the number of times the nozzle head 1 has run reaches the set value F after that. , By the time the blank feed amount of the fabric 10 reaches the set value G, the seam 18
Passes through the nozzle head 1 and beyond its position 19. Therefore, when the seam 18 of the fabric 10 passes through the nozzle head 1, the nozzle head 1 does not run, the fabric 10 is fed in a blank, and is not printed. Therefore, the seam 18 of the fabric 10 does not come into contact with the nozzle head 1 and the fabric 1
No stain of 0, clogging of the nozzle head 1 and breakage of the nozzle head 1 do not occur. Then, after passing through the seam 18,
The nozzle head 1 runs again, and the fabric 10 is printed again.

When the number of running times n of the fabric exceeds the set value N, it means that the fabric 10
Means that the number of times the nozzle head 1 has traveled exceeds the set value N, and when the other detection device 24b does not detect the seam 18 of the cloth 10, it is detected by the other detection device 24b. Something is wrong, cloth 1
This means that the seam 18 of the fabric 10 was not detected even when the seam 18 of 0 reached the position of the detection device 24b. Therefore, even if the number of times n the nozzle head 1 travels exceeds the set value N, the other detecting device 24b causes the cloth 10
When the seam 18 is not detected, the control device 25 controls the endless belt 3 and the printing unit 2, and the endless belt 3, the cloth 10 and the nozzle head 1 are temporarily stopped. Therefore, the seam 18 of the fabric 10 does not come into contact with the nozzle head 1. Further, at the same time, the control device 25 causes the alarm device 26 to
Is activated, and the alarm device 26 alerts the emergency. Therefore, an emergency can be dealt with appropriately.

の歩留まりの低下を防止することもできる。In the embodiment shown in FIGS. 3A to 3D, even if the skew angle of the seam 18 is small, the fabric 10 is fed by a fixed amount G, and the yield of the fabric 10 is reduced. Therefore, as shown in FIGS. 5A to 5D, the number of times of travel F and the idle feed amount G are calculated by the computing device 25 based on the number of times of travel n of the nozzle head 1, the skew angle of the joint 18 is large, and the nozzle 1 When the number of times of running n is large, the number of times of running F is decreased and the idling amount G is increased accordingly.
On the contrary, when the skew angle of the seam 18 is small and the number of times n of the nozzle 1 travels is small, the number of times F of travel is increased and the idling amount G is decreased accordingly. This gives the fabric 10
It is also possible to prevent a decrease in yield.
