BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention controls an automatic embroidery sewing machine in which various kinds of operations performed when the sewing machine is stopped during embroidery are performed by a kind of stop instruction code and the operation can be set in one kind. It is about the method.

[0002]

2. Description of the Related Art Conventionally, as a stop operation instruction for an automatic embroidery sewing machine, a stop instruction code itself for stopping the automatic embroidery sewing machine has a meaning. That is, the function code punched on the embroidery tape itself has a meaning such as a stop code, a color change code, a boring start code, a boring end code, a thread cutting code and an end code. For these stop instruction codes that are not in the function code of the tape itself, it is necessary to edit the embroidery data. This example is an offset code or an interlaced code. In addition to this, there is a method of confirming the setting state for each different operation by the count number of the stop instruction code of the automatic embroidery sewing machine and operating according to the specified setting. The setting when specified by this method was the color change setting or the offset setting. For the method of changing the operation at the time of stop, the former changes the stop instruction code itself of the automatic embroidery sewing machine,
The latter was a method of changing the settings related to each operation setting. Further, in order to increase or decrease the operation itself at the time of stop, the former needs to add the stop instruction code and the latter needs to add the operation setting item itself.

[0003]

However, when the operation designation at the time of stopping the automatic embroidery sewing machine is the stop instruction code, the change of the operation designation must directly change the data of the embroidery pattern by an operation such as editing. , There is a problem that the original embroidery pattern data is changed. Further, in the case of the method of changing the operation settings, there are cases where the setting items to be changed may extend to a plurality of times, which is troublesome. Further, regarding the increase / decrease of the operation at the time of stop, when the operation designation is the stop instruction code, there is a problem that the number of the stop instruction codes is restricted. Also, in the case of operation setting,
When the number of operation setting items increases, hardware changes such as a change of the operation panel may occur, resulting in a cost problem.

Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to make it possible to change the operation at the time of stop by one kind of setting item without changing the basic data of the embroidery pattern when changing the operation instruction. Further, it is an object of the present invention to provide a control method for an automatic embroidery sewing machine that does not require increase or decrease of a stop instruction code and does not require increase or decrease of operation setting items even when the operation at stop is increased or decreased.

[0005]

In order to achieve the above object, the present invention is directed to an embroidery frame that holds an embroidered material in a developed state, and an embroidery that reciprocates through the embroidery material held by the embroidery frame. In an automatic embroidery sewing machine including a needle and relative movement means for changing the relative positional relationship of the embroidery frame, an operation setting means for instructing an embroidery operation for each stop instruction code of the automatic embroidery sewing machine and the order of this operation setting are set. A first storage means for storing and a second storage means for storing the operation content according to the order of the operation setting are provided, and when the embroidery is stopped, the automatic embroidery sewing machine is controlled according to the setting content.

[0006]

In the control method for the automatic embroidery sewing machine of the present invention having the above-described structure, the operation setting means instructs the embroidery operation for each stop instruction code of the automatic embroidery sewing machine, and the operation setting order is the first.
The second storage means stores the operation content according to the operation setting order, which is stored by the storage means of
Since the automatic embroidery sewing machine is controlled according to the setting contents, when changing the operation instruction, the basic data of the embroidery pattern is not changed,
The operation when stopped can be changed with one type of setting item.
Moreover, it is not necessary to increase / decrease the stop instruction code and increase / decrease of the operation setting item even when the operation at the time of stop is increased / decreased.
