Abstract: In the large-diameter bobbin mode of the bobbin winding device, the switching lever is arranged at the switching position, and the interlocking lever is rotated to the blocking position blocking the lowering of the thread trimming holder at the raised position. Therefore, the small-diameter bobbin is arranged above the regular mounting position if it is mounted on the spool shaft. Thus, the engaging hook of the bobbin stopper does not engage with the upper end portion of the core portion of the small-diameter bobbin, and the engaging hook and the thread trimming holder do not sandwich the small-diameter bobbin vertically. Therefore, when the spool shaft is rotated by the spool motor in this state, the bobbin thread is not wound around the small-diameter bobbin since it idles with respect to the spool shaft.

Abstract: Bobbin case containing a lower thread bobbin mounted in a rotary hook of a sewing machine is exchanged for a new bobbin case by the bobbin case being transferred between the rotary hook and a bobbin stock section provided apart from the rotary hook. Transfer mechanism reciprocatively transfers a bobbin grasping device, grasping a bobbin case at a distal end portion of a chuck section, between the rotary hook and the bobbin stock section. In a predetermined position of a transfer stroke of the bobbin grasping device, an orientation change mechanism changes the orientation of the chuck section, being transferred toward the rotary hook, so that the chuck section faces toward the rotary hook, and changes the orientation of the chuck section of the bobbin grasping device, being transferred toward the bobbin stock section, so that the chuck section faces toward the bobbin stock section.

Abstract: A bobbin case tool to aid in the removal and installation of a prior art bobbin case on a sewing machine. The bobbin case tool includes an elongated arm having a clearance, a pair of lead in chamfers, a locking tooth disposed between the pair of lead in chamfers, and a locking tooth face. In application, the bobbin case tool designed to engage a releasing lever of the bobbin case and operatively pivot the releasing lever to an unlock position. The bobbin case tool is positioned so that the locking tooth is engaged in a spindle clearance of the releasing lever. The releasing lever of the bobbin case is rotated by the bobbin case tool until the releasing lever forces a locking plate of the bobbin case out of a spindle locking groove of a sewing machine's bobbin holder.

Abstract: In a thread exchanger device for a sewing machine, a rotary cassette has a plurality of bobbin casings along a circumferential direction thereof. A cassette driver is provided to rotationally drive the rotary cassette to select one of the plurality of bobbin casings so as to move it to an exahangeable position. A chuck is provided to take the bobbin casing off the rotary cassette on the one hand, and attaching to the rotary cassette on the other hand. A chuck driver is provided to alternately move the chuck toward a rotary bobbin frame, and move it toward the exchangeable position.

Abstract: An automatic dual bobbin mechanism is provided. A housing containing two unique bobbin casings and bobbins therein oriented side-by-side with the sewing needle and thread passing between the bobbin casing pair replaces the convention single bobbin configuration. The bobbin pair acts in a tag-team operation whereby one bobbin supplies thread to be stitched into a fabric while the second bobbin is simultaneously filled with thread from an external source. When the first bobbin is emptied, the bobbin pair is rotated 180.degree. inside the housing. The second bobbin, now full, supplies thread for continued stitching while the first bobbin is refilled with thread supplied by the external source. The specially designed bobbins and bobbin casings allow for automatic rethreading of the empty bobbin and cutting of the bobbin thread from external source, thus eliminating the need to manually remove the empty bobbin and assembly, replace with a full bobbin and rethread.
Abstract translation: 提供自动双线轴机构。 包含两个独特的筒管和其中的线轴的壳体与缝纫针和穿过筒管套之间的线并排定向，代替了常规的单筒管配置。 线轴对以标签组合的方式起作用，其中一个纱管将待缝合的织物缝合到织物中，而第二纱管同时从外部源填充线。 当第一个筒管清空时，筒管在壳体内旋转180°。 当第二个线轴被外部电源提供的线圈重新填充时，第二个线轴现在已满，为连续缝合提供线。 专门设计的线轴和梭壳允许自动重新套管空筒管和从外部源切割底线，从而无需手动取出空筒管和组件，更换为全筒管并重新布线。

Abstract: The disclosure is directed to automatic bobbin rewinding for sewing machines. A two-station mechanism is provided enabling bobbins to be transferred from a winding position to a sewing position, with one bobbin being at all times in each position. When a bobbin is exhausted, that bobbin and its case are removed from the sewing machine and, simultaneously, a filled bobbin is removed from the winding position and combined with its case. The bobbin positions are then reversed, enabling the filled bobbin and its case to be inserted in the sewing machine, while the just-removed bobbin is separated from its case and inserted in the winding position. The filled bobbin remains attached to the main thread supply until it is inserted in the sewing position, enabling the thread to be guided and controlled until picked up by the sewing mechanism, thus avoiding the need for manual intervention. With the old bobbin in the rewind position, the remaining, unused thread is first extracted from it, and then the thread supply is guided into engagement with the empty bobbin in preparation for rewinding. The rewinding operation is carried out while the filled bobbin is being used in the sewing operation, so that there is continuity of operation of the sewing machine.
Abstract translation: 本发明涉及用于缝纫机的自动筒管重绕。 提供了一种两站机构，使得筒管能够从卷绕位置转移到缝纫位置，其中一个筒管始终处于每个位置。 当筒管排出时，将该筒管及其壳体从缝纫机上取出，同时将填充的筒管从卷绕位置移除并与其外壳相结合。 然后将梭芯位置反转，使填充的筒管及其壳体插入缝纫机中，同时将刚卸下的线轴从壳体分离并插入卷绕位置。 填充的线轴保持连接到主线供应器，直到其插入缝纫位置，使得线可以被引导和控制，直到由缝纫机构拾取，从而避免了手动干预的需要。 随着旧卷轴位于倒带位置，首先从其中取出剩余的未使用的螺纹，然后将螺纹供给引导与空筒管接合以准备倒卷。 在缝纫操作中使用填充的线轴时进行倒带操作，使缝纫机具有连续的操作。
