Automatic bobbin and bobbin carrier changing apparatus for sewing machine |
摘要 |
An apparatus for changing bobbins and bobbin carriers in a sewing machine utilizes a magazine having an opening, containing a bobbin carrier, aligned between the bobbin housing and an electromagnet which pushes the bobbin carrier through the opening into the bobbin housing and then withdraws. The magazine withdraws; the electromagnet moves adjacent the bobbin housing, and in withdrawing pulls a spent bobbin carrier therefrom and drops it. The magazine moves into alignment again between the bobbin housing and the electromagnet, and the cycle repeats. A computer, responsive to apparatus positions, regulates pneumatic valves and an electrical source to automatically effect operations.
