Description

  The present invention relates to a topping device that removes a knitted fabric from a knitting needle of a needle bed and deposits it in a magazine in which magazine needles are arranged.

  In flat knitting machines, the knitting needle is advanced from the opposite needle bed across the mouth part to the tooth opening, and the knitting yarn fed from above the tooth opening is hooked on the hook of the knitting needle and pulled into the needle bed, thereby The organization is done. The knitting yarn is fed to the tooth mouth from the yarn feeder of a yarn feeding member that reciprocates in the longitudinal direction of the needle bed above the tooth mouth. By using such a flat knitting machine, for example, a sweater or a cardigan can be knitted without sewing.

  On the other hand, there is a need to complete clothing by linking a plurality of knitted fabrics for design reasons. For example, a body and a bag are separately knitted with a sweater or the like, and linking is performed in a subsequent process. In this case, if linking is performed in a state in which the stitches at the joint position between the body and the heel are associated with each other, a sweater with a beautiful finish and a comfortable fit can be obtained. However, when linking, it is complicated and time-consuming to match the finished body and knitted stitches one by one, so the production efficiency is poor.

  In order to solve the above problems, for example, topping devices described in Patent Documents 1 and 2 have been proposed. The topping device includes a shaft portion in which topping needles corresponding to the needle bed knitting needles are lined up one by one, and an arm that supports and moves the shaft portion, and automatically removes the knitted fabric from the knitting needles on the needle bed. Is a device that deposits in a magazine in which magazine needles corresponding one-to-one are arranged.
