Abstract
In order to switching yarns used for knitting by switching a plurality of yarn feeders, a knitting member switching apparatus is provided. The knitting member switching apparatus includes a plurality of holders provided on a side of a carriage, a stopping device provided on an end portion such as a left side end on a needle bed. The stopping device includes a plurality of stopping stands and switching mechanisms in correspondence with the holders, and is further provided with a control device for letting the carriages travel and for selecting knitting needles based on knitting data.
Claims14
A removable moving member for knitting having a base end portion and a front end portion, in which the base end portion is mountable on and dismountable from a travel member that travels along a needle bed of a weft knitting machine, the moving member being carried by the travel member without using a rail when the moving member is mounted on the travel member, wherein an operation of knitting a fabric is performed at the front end portion when the base end portion is mounted on the travel member comprising:
- a hook member provided on the base end portion, and switchable between a hook state in which the hook member is mounted on the travel member including a support member to be hooked to the travel member by sandwiching the support member in a vertical direction, and a non-hook state in which the hook member is not hooked on the travel member;
- and
- a biasing device, provided on the base end portion, to bias with a spring, the hook member maintaining a hook state on the travel member when mounted on the travel member,
- wherein the hook member is switchable from the hook state to the non-hook state against a biasing force of the biasing device when a predetermined external force is applied.
The weft knitting machine of 4, wherein the switching member includes:
- a stopping control lever, projecting from the stopping member to one side of a path on which the travel member travels such that the stopping control lever is along the path, the stopping control lever being swingingly displaceable around a supporting point provided on the other side of the path, and being slidingly abutable against the other sides on the hook member when the travel member, on which the removable moving member for knitting, is mounted moves closer from the one side;
- and
- an actuator to switch the stopping control lever between a state in which an external force for switching the hook member to the non-hook state is not applied, and a state in which the external force is applied,
- wherein the stopping member includes a stopper portion provided on the other side of the path, to allow the travel member to travel while preventing the movement of the removable moving member for knitting.
