Description

Technical Field

[0001] The present application generally relates to the technical field of textile machinery and equipment, and particularly relates to a drive system, a control system, a drive mechanism, a flat knitting machine and a control method for a flat knitting machine's yarn guide rail, knitting head, and yarn feeder. Background Art

[0002] When a computerized flat knitting machine drives the knitting head to reciprocate along the knitting head guide rail, it drives components such as cams and selector devices on the cam plate, enabling the components on the cam plate to push the knitting needles on the needle plate to reciprocate, and driving the yarn feeder to reciprocate along the yarn guide rail, thereby achieving knitting. At present, when the yarn feeders on a yarn guide rail move, there are spatial conflicts. (For example, if there are three yarn feeders, namely Yarn Feeder A, Yarn Feeder B, and Yarn Feeder C, on a yarn guide rail, and only Yarn Feeder B is used when knitting a certain row, then there will be a situation where Yarn Feeder A or Yarn Feeder C occupies the path. In this case, there is a spatial conflict between Yarn Feeder B and Yarn Feeder A or Yarn Feeder C.) Generally, only one or two yarn feeders are supported to work on a single yarn guide rail. When multiple yarn feeders are required for a flat knitting machine, multiple yarn guide rails need to be installed, resulting in waste of space and resources.

[0003] On the other hand, the drive of the knitting head of a flat knitting machine usually adopts an intermediate drive mechanism, resulting in a complex drive structure, large volume, high noise of the knitting head, and increased machine maintenance costs.

[0004] On the other hand, the drive of the knitting head and the drive of the yarn feeder of a flat knitting machine are completely independent, resulting in a large volume, high cost, high noise, and complex structure of the flat knitting machine, and increasing the production cost and maintenance cost of the machine.

[0005] Chinese Patent Application (Application No.: 202010067396.7, Application Date: January 20, 2020; Publication No.: CN111101274A, Publication Date: May 5, 2020) proposes a guiding device for a flat knitting machine's yarn feeder based on a linear motor with multiple movers. This application connects the driver to the stator and controls the stator to enable the yarn feeders on each yarn guide rail to move simultaneously and independently. This application does not meet the market demand that each yarn feeder on a yarn guide rail can move separately and independently, nor does it meet the market demand that a yarn guide rail supports several yarn feeders to work cooperatively.

[0006] Chinese Patent Application (Application No.: 201810394649.4, Application Date: April 27, 2018; Publication No.: CN108517616A, Publication Date: September 11, 2018) proposes a magnetic levitation type flat knitting machine head movement device. This application uses an electromagnet on the upper part of the knitting head and a permanent magnet array under the knitting head to make the knitting head levitate magnetically. This application has problems such as complex structure, high production and maintenance costs, and large heat generation. Summary of the Invention

Among them, the notched guide rail (201) refers to a guide rail with a notch, which forms a complete guide rail with a certain movable position guide rail (2021) of the movable guide rail (202) and is used as the movement guide rail for the yarn nozzle required when knitting a certain row. The guide rail moving mechanism (203) is used to move the movable guide rail (202) so that a certain movable position guide rail (2021) of it forms a complete guide rail with the notched guide rail (201) for the yarn nozzle to reciprocate on it.

[0067] The implementation method is as follows: 1). When a certain yarn nozzle is not required for knitting a certain row, when the yarn nozzle stops on the movable position guide rail (2021) of the movable guide rail (202), the guide rail moving mechanism (203) moves the movable guide rail (202) to make way for other working yarn nozzles, and the other certain movable position guide rail (2021) forms a complete guide rail with the notched guide rail (201) for other yarn nozzles to move; 2). When a certain yarn nozzle is required for knitting a certain row, the guide rail moving mechanism (203) moves the movable guide rail (202) to bring the yarn nozzle back onto the notched guide rail (201).

[0072] In this embodiment, optionally, it further includes a yarn nozzle zero position component (107). The yarn nozzle zero position component (107) is used to represent the zero position of the yarn nozzle.
