Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is arranged at a required position outside a knitting machine body having a main machine needle bed and a rubber machine needle bed, so that a plurality of knitting yarns can be separated from each other. A knitting yarn restraining device for restraining is provided, and a main machine carriage and a rubber machine carriage are slidably installed on each needle bed, and the knitting yarn restraining device is connected between both carriages and the knitting yarn restraining device, which are connected to each other. This invention relates to a double-sided knitting machine that allows exchangeable yarn.

[Prior Art] Conventionally, a double-panel type knitting machine has a yarn restraining device arranged on both the left and right sides of the knitting machine main body, and yarn is exchanged between each yarn restraining device and a carriage. For example, in 1987,
As described in Publication No. 45192, a knitting yarn holding section is provided approximately in the left and right center of the knitting yarn passage provided between both carriages, and both carriages are always connected to both left and right sides of the yarn holding section. When exchanging yarn between both carriages and one of the yarn restraining devices, one connecting member on the side closer to the knitting yarn restraining device connects both carriages. When the connection is released, the knitting yarn passage is opened, and the yarn can be exchanged between one of the yarn restraining devices and the carriage.

However, in the above-mentioned knitting machine, when the connection between both carriages by one connection member is released when changing the knitting yarn, the other connection member maintains the connection state of both carriages, completely unrelated to the release operation. Furthermore, since each connecting member is operated independently when replacing yarn, there is a problem in that the number of parts increases, the assembly becomes troublesome, and the manufacturing cost rises.

This invention has been made in consideration of the above circumstances, and its purpose is to connect both carriages by interlocking both connecting members without having to operate the pair of connecting members individually when exchanging yarn. Connect while ensuring the state is maintained.
It is an object of the present invention to provide a double-panel type knitting machine capable of switching the release to an opposite relationship, and which can be manufactured at low cost with a simplified configuration.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a plurality of knitting yarns are arranged at required positions on both sides of a knitting machine body including a main machine needle bed and a rubber machine needle bed. a pair of yarn restraining devices that are removably restrained, respectively; and a pair of yarn restraining devices that are slidably installed on each needle bed, and in the connected state, knitting yarn can be exchanged between the yarn restraining devices. A main machine carriage, a rubber machine carriage, a knitting yarn passage formed between both carriages, a knitting yarn holding section provided approximately at the left and right center of the knitting yarn passage and holding the yarn in a removable manner, and the knitting yarn. A pair of carriages are attached to either one of the carriages on the left and right sides of the holding part and are movable to be switched between a connection position where the two carriages are connected across the knitting yarn path and a release position where the connection between the two carriages is released. a coupling member and one of the carriages, operatively coupled to both coupling members on the coupling member, for switching one of the coupling members from a coupled position to a disengaged position in relation to the sliding direction of the carriage, and during the switching operation; and a switching member for switching the other from the release position to the connection position.

[Operation] In relation to the sliding direction of the carriage, one of the pair of coupling members is switched from the coupling position to the release position by the switching member, while the other is switched from the release position to the coupling position, and during the switching operation. However, both carriages are always kept connected by at least one connecting member. Further, the knitting yarn can be introduced into the yarn holding section in the yarn passageway from the side of the connecting member disposed in the release position.
