Creation, storage, and transfer of needle implantation data as a means for setting the needle implantation conditions are performed using a personal computer and operated and managed by a disk.

The structure of the program in the disk is as shown in FIG.
The main program is called by auto-start, and each mode can be selected and the needle setting conditions can be set interactively by CRT.

FIG. 6 shows a program in the ROM on the NC side, which comprises an automatic mode, a manual mode, a communication control mode program and the like.

Function To set the implanting conditions, first call the top data creation / edit mode of the personal computer.

7 and 8, the on-wire width W, crown width C, horizontal feed pitch M, constant increase / decrease amount S, vertical feed amount T, number of vertical lines T are input. _A , vertical feed width
Set T _B , lateral shift amount Z, and the like.

The input needle data is NC by RS-232C mode.
Transferred to unit.

Next, the mode is set to the manual mode, and the position of the pulsar (9) connected to the θ-axis driving device is set to a predetermined position in the vicinity of the needle placement means, and the position detector is adjusted.

 The needle placement origin is manually determined at a predetermined base cloth position.

Next, automatic operation using data created by a personal computer is ninth.
This is performed based on the flowchart of the automatic mode shown in FIG.

The changeover switch is switched to the automatic mode, and it is first confirmed whether or not the needle is at the original position of the needle.

Counter initialization is performed such that the number of vertical lines T _A is 1 and the amount of lateral movement X _N is 0, and one crown is implanted in the base cloth by rotation of the θ-axis motor based on predetermined needle implantation conditions.

While comparing the values calculated from the output from the position detector, such as the lateral movement amount data set, the lateral current position calculation, the lateral movement calculation, etc., with the values initially set by the needle implantation condition setting means, X values are sequentially determined. The lateral movement is performed by the driving of the shaft motor, and the needle implantation in the first row is performed.

Next, the Z-axis motor is driven based on the set value of the base cloth feed amount T, and the base cloth is fed by a predetermined feed amount by the rotation of the feed roller.

Next, the X-axis motor is driven based on the set value of the lateral displacement amount Z, the initial position of the second horizontal line is determined, and the needle placement of the second line is sequentially performed. Similarly, X-axis + direction, - it is Uehari a predetermined Uehari tissue toward a predetermined vertical number T _A is Uehari.

Then no Uehari base cloth feed amount T _B amount corresponding base fabric by the driving of the feed Z axis motor for moving the base fabric top clothing one roll which is free Uehari portion is manufactured. Similarly, the required amount of top needle cloth is implanted based on the initially set needle implantation conditions.

When the top needle implantation device of the present invention is used, the lateral displacement amount Z is sequentially changed as shown in FIG. 10, or as shown in FIG.
The vertical feed amount T can be changed sequentially.

In addition, the lateral feed pitch M and the fixed magnification increase / decrease S can be changed one crown at a time, and the values of Z, T, M, S, and the like can be changed as appropriate in combination. Needle is made.

The needle implantation can be easily performed even if the needle implantation pattern is complicated.

Conventionally, when changing the needle implantation conditions, the replacement gears, cams, and the like are exchanged, and a high degree of specialized knowledge is required for the adjustment, which requires a great deal of man-hours for adjustment. It is an invention having an excellent effect such that it can be easily changed simply by setting the initial needle implantation conditions, and the number of adjustment steps can be significantly reduced.
