Description

[Detailed Description of the Invention] [Industrial Application Field] The invention is to sequentially suppress the stitches of n knitted fabrics knitted by the reciprocating movement of the carriage in a flat knitting machine, completely preventing the stitches immediately after knitting from floating up. This invention relates to a presser device for suppressing stitches.

[Conventional technology]

In order to adapt to the knitting of stitches by the reciprocating movement of the carriage, a conventional presser was disclosed in JP-A-58-46156, in which separate pressers were provided for knitting during forward movement and for knitting during backward movement. ing.

[Problem that the invention attempts to solve]

In the conventional pressers provided for forward and backward movements, one presser is provided for both reciprocating movements, and all of the stitch suppressing surfaces of these pressers use the same form, so that the stitch suppressing action is maintained from beginning to end. There has been no attempt to effectively suppress stitches under the same conditions in accordance with the properties of the knitted fabric.

However, in stockinette knitting, as shown in Figure 8A, the knitting machine is biased to one side of the needle side in the sinker opening C in the front and back Izu 几-even needle a''''C''C knitting combination, as shown in the same figure. It is advantageous to widen the entire width of the stitch holding surface of the presser, as shown in FIG. In comparison, it is desirable to change the restraining effect depending on the properties of the silk fabric, such as the fact that it is advantageous to press with a 7-ply yarn with a small width.Also, in knitting experiments, it has been found that in the case of Amagasa cotton, the width of the cloth is wide and the flat shape is In the case of rubber knitting, a relatively small and round cross-section restraining surface has been used to obtain good results.

However, in knitting work, there is often a rubber knit followed by Tenkasa cotton in one garment.Therefore, in order to use the irregularly shaped presser 7 knit to correspond to the conventional method, operation must be stopped each time. It would have been impossible to do so without replacing the footstrap.

[Means to solve the problem]

The present invention solves the above-mentioned problem that the conventional presser device cannot select and use a suitable stitch suppressing foot according to the properties of the knitted fabric, and the present invention solves the problem that the conventional presser device cannot select and use a suitable stitch suppressing foot according to the properties of the knitted fabric. This machine is equipped with a plurality of presser feet, which can be selectively used at any desired time.The first invention is to attach a plurality of presser feet to a carriage for five knittings, and to move the base plate reciprocally along the upper surface of the needle bed. For those equipped with pressers for stitch control for forward and backward movements, are there pressers for forward and backward movements? A pair of pressers are provided at the front and rear, so that each presser can be moved up and down independently and locked in its vertical movement position, and the width of the pressing surface of the 7 stitch pressers of each pair of front and rear pressers is set within the sinker opening of the knitting machine. The second invention is characterized in that one of the pressers is made larger and the other smaller, and the second invention is characterized in that a pair of forward and backward movement tonneau pressers according to the first invention is provided at the front and rear, respectively, and the board on which the pressers are provided is locked in the upward movement position. A slider is provided at the reciprocating end of the carriage for releasing the presser, and the reciprocating end of the carriage is provided with a control pin that acts on the slider, a guide cam that releases the presser that is locked in the lower position and moves the presser upward, and a guide cam that releases the presser that is locked in the lower position and moves the presser upward, and The main feature is that it is equipped with a guide cam that moves the presser downward.

[Effect]

The device of the present invention selects all 7-stitch pressers suitable for the silk fabric according to the content of each pair of front and rear pressers equipped for forward and backward movements, and performs full presser operation.
The selected presser is locked in the lower moving position, and the other inactive pressers are locked in the upper moving position, and the selected presser is knitted while holding the stitches in 7 rows during forward or backward movement, or all the pressers are knitted. Knitting is performed by pausing at the moving pupil, and the selection and use of the presser, as well as the control of its operation and pausing, are controlled by the control bins installed at both ends of the knitting machine when the carriage reaches the end of the knitting course. The operating presser is unlocked by the movement of the slider, and the 4-guide cam moves it to the upper movement inactive position and locks it, and at the same time selects one of the pair of front and rear pressers to be used for the next course. At the initial stage when the locking metal plate and the carriage change direction to perform knitting, the presser to be used is moved downward by a guide cam, and 11.
The presser is controlled so as to be fully locked and set in a stitch-restricted state, or to be held in a resting state in the next knitting course.

Further, at the reciprocating end, there is a guide cam (c) for downward movement which abuts against the locking protrusion (9) of the presser in order to move the presser held in the upward movement position downward; The locking protrusion (9) of the pressed presser is used to move the pressed presser upward.
An upward movement guide cam (E) that abuts against the upper movement guide cam (E) is fixed to a fixed member such as a guide rail for moving a yarn guide in a VC knitting machine shown in FIG. 1, respectively.

In addition, at the front end of the upward movement guide cam (E), in the downward movement position, the protruding piece (9) that protrudes and engages into the support hole (IIS) of the board (3) is fully pulled out to lock or release the presser. The slanted cam part @ is fully formed, and the guide cam (C) (4) is installed with the upper movement cam (4) as the terminal position, and the lower movement cam (C) is located inside the lower movement cam (C). This is a holding cam consisting of a projecting piece (9) that is connected to the cam (5) and extends outward.

In the above embodiment, the carriage (3) is fully shown in FIG. The retaining protrusion (9) is in the downward movement position and is fitted into the support hole OQ of the base plate (4) and is immovably locked therein. Therefore, the retainer (5'a) of the presser (5a) is As shown in Figure 5, the stitch presser is in operation, and the presser for double action (
