Description

[Detailed description of the invention] This invention forms a main needle bed in which a large number of main knitting needles are arranged in a row, a flat knitting path that slides on the main needle bed and guides the main knitting needles, and a pattern knitting path in front of the flat knitting path. a main carriage, a sub-carriage forming a sub-knitting path for sliding on a sub-needle bed in which a large number of sub-knitting needles are arranged in parallel in front of the main needle bed, and guiding the sub-knitting needles; In between, a rear yarn opening passes below the sub-knitting needles passing through the knitting path of the sub-knitting needle and feeds yarn to the knitting needles passing through the flat knitting path of the main carriage, and a rear yarn opening feeds yarn to the knitting needles passing through the pattern knitting path of the main carriage. This invention relates to an improvement of a double-plate knitting machine for pattern knitting which is provided with a front thread opening for threading. When knitting pattern stitches with this type of knitting machine, it is difficult for the knitted fabric to slip out to the back of the collar because it is not possible to provide a knitting press plate as in the so-called hand knitting machine, especially when knitting with a tight gauge with thin threads. There was a fear that normal stitches could not be formed.

The present invention eliminates the above-mentioned drawbacks by protruding a flattening plate from above the forward direction of the knitting needles passing through the main carriage plain knitting path toward the stem of the knitting needles, and also makes elastic contact with the knitting needles. With this structure, the flattening action is always ensured despite the existence of dimensional differences in the height of the knitting needles during manufacturing and assembly.

Hereinafter, a specific example thereof will be explained based on the drawings.

Swinging cam for retracting knitting needles passing through X, 10,1
0' is an intermediate spacer wall that retreats the knitting needles that have been retreated by the swing cam 9 on the inner inclined surface, and retreats the knitting needles passing through the plain knitting path XX on the outer inclined surface; 11 and 11' are the intermediate spacer walls. 10, 10', and the intermediate partition wall 10,
A swing cam 10' further retreats the knitting needles that have been retracted, and valve cams 12a and 12a' 12 that guide the knitting needles passing through the plain knitting path XX to the knitting cams 4 and 4' are backward cams.

Reference numeral 13 denotes an auxiliary carriage that slides on the auxiliary needle bed 2, and a cord cam shown in FIG. 1 is disposed on the back surface of the auxiliary carriage. That is, reference numerals 14 and 14' designate sub-knitting cams that are installed at positions opposite to the knitting cams 4 and 4' of the main carriage 3, and have opening/closing cams 14a and 14a' pivotally mounted at the rear. Reference numeral 15 denotes a front partition wall 16, 1, which forms a front rest passage in the front part and has a retreating part 15a in the middle for retracting the knitting needles advanced by the sub-knitting cams 14, 14';
Reference numeral 6' denotes a secondary intermediate partition wall 1 that guides the knitting needles retreated by the front partition wall 15 to the secondary knitting cams 14, 14'.
Reference numerals 7 and 17' designate subtack cams, 18 and 18' auxiliary lowering cams, and 19 and 19' subpar pulling-up needle lowering cams for opening and closing the front rest passage.

Next, the connection plate 20 that connects the main carriage 3 and the sub-carriage 13 will be explained. The connecting plate 20 is fixed to both carriages 3, 13 by tightening screws 21,
A rear yarn opening 22 for feeding colored yarns and a front yarn opening 23 for feeding ground yarns are fixed to the central part. Sub knitting needle raising plates 24 are integrally fixed to the left and right sides of the back thread opening 22. Reference numeral 25 designates a flat punching plate, which has chevrons such as 25a and 25b formed at its tips and projects from above and in front of the knitting needles NX passing through the main carriage flat knitting path XX in the forward and backward direction of the knitting needles toward the stems of the knitting needles. 2
Reference numeral 6 denotes a support base for the flattening plate 25; 27 denotes a pin fixed to the flattening plate 25; the pin protrudes from the elongated hole 28 of the support base 26, and a wire spring 29, which is an elastic member, is hooked thereon;
As a result, the flattening plate 25 can be slid up and down and is always pulled in the direction indicated by the two-dot chain line in FIG. 4 (downward). Furthermore, the flattened plate is formed from a thin plate so that it can be bent in the vertical direction. Reference numeral 30 denotes a bellows tilting member for pushing backward the bellows of the main knitting needles erected by the magnet 31; 32 is a magnet for raising the bellows; 3;
Reference numeral 3 denotes a guide member for standing up and guiding the bellows.

The operation of the configuration as described above will be explained below.
First, the knitting needles to be knitted on the main needle bed 1 are sorted into two positions, front and back, and are designated as front main knitting needles NY and back main knitting needles NX. Further, the thread T is inserted through the front thread opening 23, and the thread S is inserted through the rear thread opening 22. The cams of both carriages 3 and 13 are arranged as shown in solid lines in FIG. In this state, both carriages 3 and 13 are slid in the direction of arrow a. (Illustrated in the first diagram). When both carriages 3 and 13 move forward, the sub knitting needles NR arranged in a row on the sub needle bed 2 move forward by the opening/closing cam 14a and the sub knitting cam 14, and are moved upwardly from the rear thread opening 22 by the sub knitting needle raising plate 24. be raised. That is, the rear thread opening 22 is arranged between the sub knitting needles NR and the comb teeth K of the main needle bed 1. Front main knitting needle NY is knitting path Y
−X, and the rear main knitting needle NX is introduced into the flat knitting path X−
X is introduced, and each knitting needle is pulled out. When both carriages 3 and 13 further advance, the yarn S is fed from the rear yarn port 22 to the rear main knitting needles NX, and the yarn T is fed from the front yarn port 23 to the front main knitting needles NY and sub-knitting needles NR. In this case, the yarn S from the back thread opening 22 is
Since the yarn is fed below NR, the sub-knitting needle NR
There is no need to feed the yarn.

When both carriages 3 and 13 advance further, the rear main knitting needles NX and front main knitting needles NY are moved backward by the knitting cam 4' and pass the old stitches, respectively, and the rear main knitting needles NX start a new stitch using yarn S. The front main knitting needle NY forms a new stitch using yarn T. The sub-knitting needle NR is retracted by the sub-knitting cam 14' and forms a new stitch using the yarn T, passing over the old stitch.

Therefore, when the rear main knitting needles NX of the flat knitting path X-X perform flat knitting, the flat knitting plate 25
Due to the elasticity of the knitting needle NX, it comes into elastic contact with the stem of the knitting needle NX and prevents the stitch from moving forward, thereby ensuring that the knitting needle NX is completely pulled out. In addition, even if the position of the knitting needles is different up and down due to variations between parts or vibrations when the carriage slides,
The lug punching plate 25 is mounted so as to be slidable up and down and is always pressed downward by the wire spring 29, so that the tip of the lug punching plate 25 always comes into close contact with the knitting needle stem due to the elasticity of the wire spring 29. here,
Chevrons 25a and 25b are formed at the tip of the blade punching plate, and these portions have the function of reliably pushing out the old stitches from the blade.

As described above, the present invention has a main needle bed in which a large number of main knitting needles are arranged in a row, a flat knitting path that slides on the main needle bed and guides the main knitting needles, and a worn knitting path in front of the main needle bed. a main carriage, a sub-needle bed having a number of sub-knitting needles arranged in parallel in front of the main needle bed, and a sub-carriage forming a sub-knitting needle knitting path that slides on the sub-needle bed and guides the sub-knitting needles. and, between the two carriages, a rear yarn opening that passes below the sub-knitting needles passing through the sub-knitting needle knitting passage and feeds yarn to the knitting needles passing through the flat knitting passage of the main carriage, and In a double plate type knitting machine for pattern knitting, which is equipped with a front yarn opening for feeding yarn to the knitting needles passing through the main carriage passageway, the tip of the knitting needles passing through the main carriage plain knitting passageway is located at the top of the front in the forward and backward direction of the knitting needles. A flattening plate having a plurality of chevrons formed thereon and a support plate supporting the flattening plate are provided, and a pin and the pin are slidably fitted into one and the other of the flattening plate and the support plate, respectively. A knitting auxiliary device for a knitting machine, characterized in that a slotted hole is formed, the flattened punching board is slidably protruded in the direction of the surface thereof, and the flattened blanking board is brought into elastic contact with the knitting needles by an elastic member. This is what we have configured.

According to this configuration, when the flat punching board comes into elastic contact with the knitting needles, in addition to its own elasticity in the thickness direction, it can also be slid and retracted in the plane direction, so that the flat punching board can be securely attached to the knitting needles. Can be bombarded. In other words, even in knitting machines where it is not possible to provide a knitting press plate on so-called hand knitting machines, the knitted fabric is difficult to slip out behind the collar, and it is difficult to form normal stitches when knitting with particularly thin threads at a tight gauge. The punching board makes it possible to ensure that the stitches are flattened.
In addition, by being configured to come into elastic contact with the knitting needles, the flattening action can always be performed reliably despite the existence of dimensional differences in the height of the knitting needles during manufacturing and assembly.
