  However, when the top spring device is provided on the horizontal frame at the upper end of the vertical frame, the vibration from the flat knitting machine main body that is generated when the carriage travels or reverses is directly transmitted to vibrate the top spring device. The vibration of the top spring device may adversely affect the yarn feeding accuracy and the electronic components provided in the top spring device, and measures such as reinforcement are required to suppress the vibration.

  The objective of this invention is providing the flat knitting machine which can suppress as much as possible the vibration of the top spring apparatus transmitted from a flat knitting machine main body, without reinforcing.

  In order to achieve the above object, the present invention is premised on a flat knitting machine that feeds a knitting yarn fed from a yarn package placed on a yarn stand from a top spring device. Furthermore, the yarn stand and the top spring device are provided on a self-propelled stand that is separate from the main body of the flat knitting machine. And the said stand is connected with the back surface of the said flat knitting machine main body by a connection mechanism so that attachment or detachment is possible.

  Further, the connecting mechanism is provided with a pin member provided in the flat knitting machine body, an insertion hole provided in the stand and through which the pin member is inserted, and a pin which is attached to the stand and is inserted into the insertion hole. It is preferable to include an engagement member that is spring-biased and engaged with the member.

  Moreover, it is preferable that the said thread stand is converted into the standing position which stands up toward the back of the said stand, and the fall position which falls down along the back surface of the said stand.

  Furthermore, it is preferable that an engagement hole that engages with the pin member instead of the engagement member when the flat knitting machine body is transferred is continuously provided below the insertion hole of the stand.

By connecting the stand with the thread stand and the top spring device to the main body of the flat knitting machine in a removable manner, the stand is separated from the main body of the flat knitting machine. The vibration from the flat knitting machine main body that is generated when the carriage travels or reverses is indirectly transmitted to the stand via the coupling mechanism. Thereby, the vibration of the top spring device can be suppressed as much as possible without reinforcing.
Further, the length of the yarn path fed from the top spring device to the yarn feeder during knitting can be kept constant, and inadvertent movement of the stand can be prevented.
Moreover, by making the stand self-propelled, the stand can be moved away from the flat knitting machine main body during maintenance of the flat knitting machine, and maintenance workability from the back side of the flat knitting machine main body can be improved.

  In addition, with the pin member protruding from the flat knitting machine body inserted through the insertion hole of the stand, the pin member of the flat knitting machine main body is engaged with the engagement member that is spring-biased to the stand. Can be easily connected by the engaging member in the insertion hole of the stand.
