Patent ID: 6874437

Claim:
A head control device for a multi-head embroidery machine having a plurality of heads, comprising: a central control unit outputting a control signal for controlling a drive state of a respective head in response to an operation of an operator, so that the plurality of heads are selectively driven, and an embroidery task is performed by the selectively driven heads; at least one head control unit for controlling the drive state of the respective head in response to the control signal from the central control unit, wherein the central control unit comprises: a setting unit for inputting a head group information for grouping adjacent heeds to perform the embroidery task, a head driving information setting the drive state of the respective head, and data necessary for the embroidery task, and for sending the head group information, head driving information, and data necessary for the embroidery task to a processor; the processor for outputting the control signal for driving a respective head control unit in response to control information input to the setting unit, and a storage unit for storing the head group information, the head driving information, and the data necessary for the embroidery task, input by the setting unit, in response to the control signal of the processor; and wherein the respective head control unit is commonly connected to grouped heads, thereby controlling simultaneously the grouped heads in response to the control signal from the central control unit to coordinate adjacent grouped heads to synthesize an operation of a single head with selective operation of the adjacent grouped heads.
