[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting a swing position of a yarn guide reed in a double Raschel machine.

[0002]

2. Description of the Related Art Conventionally, when a double-faced warp knitted fabric is knitted by a double Raschel machine having two rows of needles at the front and rear, the needles have been provided corresponding to both needle rows. The yarn guide reed performs a swinging motion that moves in the front-rear direction of the knitting machine in order to carry out a knitting yarn bridging operation for forming a stitch on the needle hook of each needle row.

The swing width of this swinging motion varies depending on the interval between the opposing needle rows and the knitting structure, and a plurality of thread guide reeds each having a role are arranged above the needle rows. Generally, a front ground yarn reed provided for knitting a base fabric in a front needle row, a rear ground yarn reed provided for knitting a base fabric in a rear needle row, and the front and rear needles A connecting yarn reed for guiding a connecting yarn for connecting a front base fabric and a rear base fabric that are respectively knitted in rows is used.

[0004] The two-sided warp knitted fabric is knitted by the yarn guide reed arranged as described above. A thick fabric, for example, a fabric having a thickness of 20 mm to 50 mm or more, is used. For knitting, it is necessary to widen the distance between the front and rear needle rows in accordance with the material thickness.

Regarding the swing width of the reed reed, especially the reed for the connecting yarn, since it is carried over to the needle rows before and after knitting the front and rear base fabrics, it is the same as when knitting thick fabrics. The swing width becomes large.

On the other hand, the front and rear ground yarn reeds for forming the base cloth need only be knitted with only the front or rear base cloth.
Their swing width may be small. Therefore, it is not necessary to make the swing width of the front and rear ground yarn reeds larger than the swing width of the connecting yarn reed. Therefore, the swing width of each of the front and rear ground yarn reeds and the swing width of the connecting yarn reeds are large. So that you can change
It has been general that swinging support shafts of supporting members for supporting these yarn guide reeds are separately provided in parallel.

However, in the above case, two or three rotatable pivots for swinging are required, and each pivot requires a large amount of mounting space for metal or the like for holding the pivot. In addition, in order to impart rotational displacement to the support shaft, it is necessary to provide a drive lever for each support shaft, and many support arms such as arms, levers, and cams attached to each support shaft. It is undeniable that a drive member is required and the drive mechanism of this type of yarn guide reed becomes complicated.

The present invention solves the above problems and, in a double Raschel machine for knitting a two-sided warp knitted fabric, simplifies the drive mechanism for the rocking motion of the yarn guide reed, and improves the lever, arm, cam, etc. The number of driving members can be greatly reduced, the swing position can be easily adjusted, and more preferably, even when knitting a material having a large material thickness, an excessive swinging motion of the yarn guide reed is suppressed,
It is an object of the present invention to provide a swing position adjusting device for a yarn guide reed that can reduce the amount of swing and keep the amount of swing to a minimum necessary amount.

SUMMARY OF THE INVENTION The present invention comprises a front and rear two-row needle row, and a front ground thread reed, a connecting thread reed, and a rear ground thread reed corresponding to the two needle rows. A device for adjusting the position of a yarn guide reed in a double Raschel machine, which comprises a yarn guide reed, and these yarn guide reeds are attached to a supporting member supported by a spindle. By providing a means for generating and synthesizing a swing displacement different from the swing displacement of the ground yarn reed at the front and rear parts in synchronization, a swing displacement independent of the swing displacement of the connecting yarn reed is generated. It is characterized in that it is added to the ground yarn reed of a part, and the action positions of the front and rear ground yarn reeds on the needle row can be adjusted.

As a result, the swing displacement of the all-fiber-conveyor reed consisting of the ground yarn reed and the connecting yarn reed at the front and rear can be summarized in a simple drive mechanism centering on one spindle. As a result, it becomes easy to adjust the swing position of each yarn guide reed, and even in the knitting of a two-sided warp knitted fabric having a large thickness, the rocking of the front and rear ground yarn reeds against the swing displacement of the connecting yarn reed The amount of movement, that is, the swing width can be reduced.

The means for synthesizing the swing displacement of the ground yarn reeds at the front and rear portions is a member that is attached to a rotatable support shaft and swings, and is a member to which the connecting yarn reeds are attached. A first support member and a swing support shaft provided on a part of the first support member so as to be rotatable, and to which a front ground yarn reed and a rear ground yarn reed are attached. 2 supporting members, the swing support shaft is moved based on the reciprocating displacement applied to one end of the second support member with respect to the swing displacement generated by the rotational displacement applied to the support shaft. The configuration is such that the swing displacement of the second support member that occurs at the fulcrum is combined.

[0012] As a result, the first reed for the connecting yarn is attached.
The swinging displacement of the supporting member and the swinging displacement of the second supporting member to which the front and rear ground yarn reeds are attached are effectively combined, and the swinging displacement of the front and rear ground yarn reeds is the connecting yarn. It becomes independent with respect to the swing displacement of the reed. As a result, the swing position of each yarn guide reed can be easily adjusted, and the swing amount, that is, the swing width of the front and rear ground reeds can be reduced.

It is preferable that the two needle rows are swung in a direction opposite to the swing direction of the yarn guide reed. As a result, the amount of rocking of the yarn guide reed is shared with the amount of rocking of the needle row, so that the amount of rocking can be minimized, and as a result, the vibration of the knitting machine can be effectively suppressed.
This leads to an improvement in the rotation speed of the knitting machine.

Cam levers for driving the stitch combs 3a, 3b are provided respectively, and displacement of the cam lever due to rotation of the cam shaft is connected to the arms on the bearing shafts 4a, 4b via a driving member such as a rod or a lever. Since this point is not the gist of the present invention, detailed illustration is omitted.

A swing displacement different from the swing displacement of the front and rear ground yarn reeds 5a and 5b synchronized with the swing of the connecting yarn reed 5c attached to the first supporting member 7 is performed. The structure for providing the synthesizing and synthesizing means and imparting the swing displacement independent of the swing displacement of the connecting yarn reed 5c to the front and rear ground yarn reeds 5a and 5b will be described in more detail.

As shown in FIGS. 3 and 4, the first supporting member 7 to which the connecting yarn reed 5c is attached is fixed to the support shaft 6 so as to be sandwiched from above and below. 71 indicates a fastening bolt for fixing. A swing support shaft 8 is fixed to each of the first support members 7, and the ground support reeds 5a and 5b at the front and rear portions are attached to the swing support shaft 8 via a bearing member 23. The member 9 is swingably fitted and attached. One end of the second support member 9, that is, the rear side end is extended and formed, and the drive rod 18b is connected to the extended end 9a. As a result, the second support member 9 swings around the support shaft 6 as a fulcrum together with the first support member 7 due to the rotational displacement of the support shaft 6 which is interlocked with the rotation of the front cam shaft 12a. At the same time, in addition to the above-described swinging, the swinging support shaft 8 can swing about the fulcrum by the reciprocal displacement of the drive rod 18b which is interlocked with the rotation of the cam shaft 12b.

As a result, the front and rear ground yarn reeds 5 are synchronized with the swing of the connecting yarn reeds 5c attached to the first supporting member 7.
With respect to the rocking motions of a and 5b, a rocking displacement different from this is generated and combined, so that the front and rear ground yarn reeds 5a,
The swing displacement independent of the swing displacement of the connecting yarn reed 5c is given to 5b.

That is, reciprocal displacement is applied to one end portion (extended end portion 9a) of the support member 9 with respect to the swing of the second support member 9 synchronized with the swing of the first support member 7. Then, a rocking displacement centering on the rocking support shaft 8 is generated, and this rocking is combined with a rocking displacement centering on the support shaft 6, whereby the ground yarn reeds 5a, 5b in the front and rear portions are formed. In contrast, reed for reed thread 5
A swing displacement independent of the swing displacement of c can be applied.

At this time, the cam shaft 12b is arranged so that the rocking displacements of the front and rear ground yarn reeds 5a and 5b are smaller than the rocking displacement of the connecting yarn reed 5c. A predetermined reciprocal displacement is given to one end of the support member 9 by the rotation of the.

That is, in the connecting yarn reed 5c, since the connecting yarn is alternately wound around the front and rear needle rows 1a and 1b for knitting the front and rear base fabrics, the distance between the trick plates 2a and 2b is large. In some cases, it is necessary to increase the amount of swing, but for the front and rear ground yarn reeds 5a and 5b, the front needle row 1a for knitting the front base cloth or the rear needle for knitting the rear base cloth is used. Since it is sufficient to guide the yarn only to the row 2b, it is not necessary to increase the swing displacement amount that much. Therefore, as mentioned above,
The rocking displacements of the front and rear ground yarn reeds 5a and 5b are set to have a smaller swing width with respect to the rocking displacement of the connecting yarn reeds 5c.

This will be described with reference to FIGS. 5 and 6. FIG. 5 shows the knitting timing state of overlapping of the yarn guide reed with respect to the rear needle row 1b when the distance between the trick plates 2a and 2b is 50 mm, and FIG. 6 shows the yarn guide reed with respect to the front needle row 1a. The state of the knitting timing of overlapping is shown.

In FIG. 5, the connecting thread reed 5c attached to the first support member is attached to the first revolving shaft 5c centered on a spindle pivotally displaced via a drive lever. It is rocked together with the support member in the direction of the white arrow A1 in the figure (on the side of the rear needle row 1b).

On the other hand, the front and rear ground yarn reeds 5a and 5b attached to the second supporting member are attached to the first supporting member via the swing support shaft. While swinging in the direction of the white arrow A1 together with the second support member, at the same time, another swing is generated with respect to the second support member about the swing support shaft, This is the arrow A
As a result of being combined with the rocking in the direction 1, the rocking displacement is suppressed as a whole, the ground yarn reed 5a at the front part is displaced so as to be separated from the connecting yarn reed 5c, and the rear part is also moved. The ground yarn reed 5b is displaced so as to approach the connecting yarn reed 5c.

Further, in FIG. 6, the connecting thread reed 5c attached to the first supporting member is opposite to the above, and the white arrow in the figure together with the first supporting member is centered on the spindle. It is swung in the direction of A2 (on the side of the front needle row 1a).

On the other hand, the front and rear ground yarn reeds 5a and 5b attached to the second supporting member are to be swung in the direction of the hollow arrow A2 together with the second supporting member. However, at the same time, another swing about the swing support shaft with respect to the second support member, particularly, a swing in the opposite direction to that in the case of FIG. 5, is generated, which is the direction of the arrow A2. As a result of being combined with the rocking of the reed, as a whole, the rocking displacement is suppressed, the ground yarn reed 5a in the front portion is displaced so as to approach the connecting yarn reed 5c, and the ground yarn in the rear portion is used. Reed 5b is for connecting yarn 5c
It is displaced so as to separate from.

That is, while the connecting yarn reed 5c is swingably displaced between the front and rear needle rows 1a and 1b, the swinging displacement of the front and rear ground yarn reeds 5a and 5b is small. It is wide. The swing position by this swing displacement, that is, the position acting on the needle row, is the swing amount of the first support member 7, the attachment position of the connecting yarn reed 5c to the support member 7, and the second support member. By adjusting the amount of rocking of 9 and the attachment positions of the front and rear ground yarn reeds 5a and 5b with respect to the support member 9, the swing positions of these ground yarn reeds 5a and 5b can be easily adjusted. it can.

The trick plates 2a and 2b shown in FIG.
Even when the interval is 24 mm, it is basically the same as the above, but depends on the swing width (swing amount) of the connecting yarn reed 5c and the swing displacement of the front and rear ground yarn reeds 5a and 5b. Swing width becomes smaller. However, the difference between the swing width of the connecting yarn reed 5c and the swing width of the front and rear ground yarn reeds 5a and 5b becomes small.

Particularly, in the actual knitting, the front and rear needle rows 1a and 1b and the trick plates 2a and 2b are basically the respective guide yarns such as the front and rear ground yarn reeds 5a and 5b and the connecting yarn reed 5c. Since it reciprocates with respect to the reciprocating direction of the reed, the ground yarn reeds 5a and 5b and the connecting yarn reed 5
The swing amount (swing width) of c is further reduced. Usually, it is about 1/2 of that when the needle row is not swinging.

The diagram of FIG. 7 shows the trick plate 2
When the distance between a and 2b is 24 mm, the raising and lowering movements of the front and rear needle rows 1a and 1b, and the ground yarn reeds 5a and 5
b and the swinging motion of the connecting yarn reed 5c are shown. In addition, the diagram of FIG. 8 shows that when the distance between the trick plates 2a and 2b is 50 mm, the up-and-down movement of the front and rear needle rows 1a and 1b, the ground yarn reeds 5a and 5b, and the connecting yarn reed 5c. Rocking motion of the.

According to these two diagrams, the swing widths of the front and rear ground yarn reeds 5a and 5b are smaller than the swing width of the connecting yarn reeds 5c, and in particular, the interval between the trick plates 2a and 2b is large. In some cases, the swing widths of the front and rear ground yarn reeds 5a and 5b are smaller than the swing width of the connecting yarn reeds 5c, and the difference between the swing widths is large.

That is, the greater the distance between the trick plates 2a and 2b, that is, the thickness of the two-sided warp knitted fabric to be knitted, the greater the effect obtained by adopting the device of the present invention.

[0049]

As described above, by employing the device for adjusting the swing position of the yarn guide reed of the present invention, it is possible to perform the swing motion of the yarn guide reed of the double Raschel machine for knitting a two-sided warp knitted fabric. The driving mechanism can be simplified, the number of driving members such as levers and arms can be greatly reduced, and the swing position can be easily adjusted.
Further, even when knitting a fabric having a large thickness between the front and rear base fabrics, it is possible to suppress an excessive swinging motion of the yarn guide reed and reduce the swinging amount to the minimum required swinging amount. As a result, vibration and noise of the knitting machine can be effectively suppressed, and thus the number of rotations of the knitting machine can be improved.
