Abstract
In the described method, for keying-in of a given operating cycle a plurality of bar codes is provided to be sequentially inputted to an electronic control unit (114) with the aid of an optical detector (126) , each bar code corresponding to a specific operation to be executed on a workpiece (116) for carrying out a particular working. The bar codes (125) are reproduced on respective adhesive labels (127) applied to a work card (115) carrying the workpiece depiction, each code (125) being disposed close to a corresponding area of the workpiece (116) on which the corresponding working is to be made.
Claims4
A method of inputting operating cycles to a sewing machine electronic control units involving the use of an electronic unit (114) in which a plurality of elementary instructions is stored to be sequentially sent to the sewing machine for driving the same in operation, which method comprises a selective batching of said elementary instructions to form a plurality of instruction batches capable of being individually identified by respective identification codes (125) and corresponding each to at least one specific operation included within the execution of a given working by the sewing machine (100), keying-in of the operating cycle comprising the following steps:
- identifying a sequence of workings to be executed for carrying out an operating cycle relating to the production of a given workpiece (116);
- selecting the specific operations to be executed for carrying out the individual workings provided in said identified sequence;
- transmitting to the electronic control unit (114), according to an order corresponding to said working sequence, the identification bar codes (125) of the instruction batches corresponding to the selected operations for the individual workings, said identification codes (125) being sequentially stored in the electronic unit (114) for defining said operating cycle;
- said identification codes (125) are in the form of bar codes disposed on a corresponding work card (115), the transmission of said codes to the electronic control unit (114) being carried out with the aid of an optical detector (126) associated with the electronic control unit;
- and
- wherein the identified working sequence is copied into said work card (115) by means of first progression indices (A, B, C, D, E, F), each of which corresponds to one of said workings and is disposed closed to a corresponding area of a workpiece (116) graphically reproduced on the work card (115).
