Abstract
Abstract A programmable sewing machine adapted to learn and store, in Automatic Learn or Key Learn Modes of operation, a series of sewing machine operations for later automatic duplication, in an Automatic Sew Mode of operation, at the same sewing rate as the initial operation, or at the peak sewing rate achieved during each operation; or, in a Control Sew Mode of operation, at a controlled lower speed. Additionally, the machine operation may be limited in a Set Up Mode to preset rates for machine speed, copy or peak speed automatic operation, number of start stitches, number of stop stitches, start speed and stop speed. The machine may be operated in the Manual Mode with provision for first tack and last tack and thread trim and wipe when desired. The automatic operation of the sewing machine may be interrupted to go into a Repair Mode during which the sewing machine may be operated manually, and, on proper command, to revert back to the Automatic Sew Mode at the particular operation which was interrupted. A Quit control is provided which permits reversion to an Initialization Mode from which a specific mode of operation may be selected. Provision is made to Erase specific learned and stored series of sewing machine operations, and to warn when the storage capacity may be exceeded.

A programmable sewing system comprising: a sewing machine having a plurality of components operable selectively manually and automatically; a programmable computer having memory means and a plurality of input terminals coupled to said sewing machine for receiving signals indicative of operation of said components of said sewing machine, and a plurality of output terminals coupled to said sewing machine for actuating operation of said components of said sewing machine; a manually actuated control panel coupled to said computer for entering sewing instructions, said control panel including display means coupled to said computer for receiving display information therefrom; said system having a first mode of operation selected by way of said control panel wherein basic sewing system operating conditions may be introduced to said computer memory means for subsequent control of said system, said conditions including maximum speed of sewing machine operation, number of start stitches initiating a sequence of stitching operations and speed at which accomplished, and number of stop stitches terminating each segment of said sequence of stitching operations, and speed at which accomplished.
Claim 2
Dependent Claim
175 words
A programmable sewing system comprising: a sewing machine having a plurality of components operable selectively manually and automatically; a programmable computer having memory means and a plurality of input terminals coupled to said sewing machine for receiving signals indicative of operation of said components of said sewing machine, and a plurality of output terminals coupled to said sewing machine for actuating operation of said components of said sewing machine; a manually actuated control panel coupled to said computer for entering sewing instructions, said control panel including display means coupled to said computer for receiving display information therefrom; said system having a first mode of operation selected by way of said control panel wherein basic sewing system operating conditions may be introduced to said computer memory means for subsequent control of said system, said conditions including maximum speed of sewing machine operation, number of start stitches initiating a sequence of stitching operations and speed at which accomplished, and number of stop stitches terminating each segment of said sequence of stitching operations, and speed at which accomplished.
Claim 3
Dependent Claim
78 words
A programmable sewing system as claimed in claim 1, wherein said system includes a second mode of operation selected by way of said control panel and operable according to at least certain of said sewing system operating conditions introduced in said first mode of operation, wherein said sewing machine may be operated by manual operation of said manually operable components, said components including a continuously variable speed drive system manually operable to obtain an operator selectable variable speed.
Claim 4
Dependent Claim
116 words
A programmable sewing system as claimed in claim 2, wherein said system includes a third mode of operation selected by way of said control panel and operable according to at least certain of said sewing system operating conditions introduced in said first mode of operation, wherein said programmable computer receives on said plurality of input terminals, and automatically retains in said memory means, signals indicative of manual operation of said components of said sewing machine, including a count of the repetitive component operations of certain of said components, a time duration for operation of certain other of said components, and a speed profile copy of the continuously variable speed operation of said variable speed drive system.
Claim 5
Dependent Claim
119 words
A programmable sewing system as claimed in claim 3, wherein said system includes a fourth mode of operation selected by way of said control panel and operable according to at least certain of said sewing system operating conditions introduced in said first mode of operation, wherein said programmable computer actuates operation of said components of said sewing machine, including said exact count of said repetitive component operations of said certain of said sewing machine components, said time durations for operation of certain other of said sewing machine components, and said speed profile copy of the variable speed operations of said variable speed drive system, according to said signals retained in said memory means in said third mode of operation.
Claim 6
Dependent Claim
138 words
A programmable sewing system as claimed in claim 4, wherein said system includes a fifth mode of operation selected by way of said control panel and operable according to at least certain of said sewing system operating conditions introduced in said first mode of operation of said components of said sewing machine, including said exact count for certain of said sewing machine components according to said signals retained in said memory means in said third mode of operation, and in derogation to those signals retained in said memory means and according to operator control imposed by way of said manually operable components for speed of said variable speed drive means up to the maximum speed for each segment of said speed profile copy and for time duration for operation of said certain other of said sewing machine components.
Claim 7
Dependent Claim
120 words
A programmable sewing system a claimed in claim 5, wherein said system included a sixth mode of operation selected by way of said control panel when in a selected one of said fourth and said fifth modes of operation and operable according to at least certain of said sewing system operating conditions introduced in said first mode of operation, wherein said sewing machine may be manually operated as though in said second mode of operation, said sewing system reverting automatically to said selected one of said fourth and fifth modes of operation on termination of operation in said sixth mode to initiate stitching where interrupted according to said signals retained in said memory means in said third mode of operation.
