Description Adjusting device for swinging position of the pliers in a double Raschel machine

〔Technical field〕

TECHNICAL FIELD The present invention relates to a swing position adjusting device for a guiding thread in a double Raschel machine.

(Background technology)

Conventionally, when knitting a double-sided warp knitted fabric with a double lashing machine having two front and rear needle rows, the conducting yarns Pro provided for both needle rows use the needles of each needle row. The swinging motion of the knitting machine in the front-rear direction is performed for the operation of bridging the knitting yarn to form a stitch on the hook.

The swing width of the slidable motion of the weft proof depends on the spacing between the opposing needle rows and the knitting structure.

Above the row of needles, there are a plurality of conductors, each having a role. In general, a front ground thread ply provided for a base fabric knitting at a front needle row, a rear ground thread prize provided for a back cloth knitting at a rear needle row, and the front and rear knees A connecting thread proof for guiding a connecting thread for connecting a front base fabric and a rear base fabric that are knitted by a dollar row, respectively, is used.

The knitting of the double-sided warp knitted fabric is performed by the yarns arranged in the manner described above, but the thickness of the fabric is large, for example, 20 mm to 5 O mm or more. To knit a thicker one, it is necessary to widen the distance between the front and rear needle rows to correspond to this material thickness. By the way, as for the swing width of the weft, especially for the connecting yarn, the swinging operation is performed on the needle row before and after the knitting of the front and back fabrics. The width increases.

On the other hand, as for the ground thread for the front and rear portions for forming the base fabric, only the front or rear base fabric may be knitted, so that the swing width thereof may be small. Therefore, it is not necessary to make the swing width of the front and rear ground yarns larger than the swing width of the connecting yarn springs. In general, it has been customary to separately provide the driving support shafts of the supporting members for supporting the yarn guides so that the swing width can be changed.

However, in the above case, two or three pivotable pivots for swinging are required, and for each spindle, a large mounting space such as metal for holding the spindle is required, In addition, in order to impart a rotational displacement to the support shaft, it is necessary to provide a drive lever on each support shaft 、, and a large number of arms, levers, cams, etc. attached to each support shaft in series. A driving member was required, and it was undeniable that the driving mechanism of this kind of yarn guide was complicated.

The present invention solves the above problems, and in a double raschel machine for knitting a two-sided knitted fabric, simplifies the drive mechanism for the swinging motion of the yarn guide, and drives the lever, arm, cam, etc. Providing a swing position adjusting device of a yarn guide that can greatly reduce the number of members and easily adjust the swing position. More preferably, the yarn guide is used even when knitting a material having a large material thickness. An object of the present invention is to provide an apparatus for adjusting the swing position of a guiding thread, which is capable of suppressing excessive swinging motion of a prize and reducing the swaying quantity to a minimum required swaying quantity.

[Disclosure of the Invention]

The present invention corresponds to two rows of needles before and after and two rows of 21 dollars. A double raschel comprising a lead yarn consisting of a front ground yarn proof, a connecting yarn proof, and a rear ground yarn proof, and having these lead yarns attached to a support member supported by a spindle. This is a swing position adjusting device for the guiding thread in the machine, and generates a different swing displacement from the swing of the ground thread for the front and rear parts in synchronization with the swing of the connecting thread for the connecting thread. A means is provided to apply a swinging displacement independent of the 摇 -movement of the connecting thread proof to the front and rear ground thread proofs, so that the working position of the front and rear ground thread proofs on the needle row can be adjusted. It is characterized by having done.

As a result, the oscillating displacements of the front and rear ground yarns and the connecting yarns of the front and rear portions of the double shell machine are combined into a simple drive mechanism centered on one support shaft. As a result, the number of driving members such as levers and arms can be greatly reduced, and the adjustment of the swinging position of each of the yarn guides becomes easy. Also, in the knitting of a double-sided warp knitted fabric having a large thickness, the amount of movement and the swing width of the front and rear ground yarn proofs can be reduced with respect to the rotational displacement of the connecting yarn proof o

The means for synthesizing the swinging displacement of the ground thread for the front and rear portions in the above-described swing position adjusting device for the leading thread is a member attached to a rotatable support shaft and swinging, and is a member for the connecting thread. A first support member to which the prong is attached, and a rotatable support shaft provided at a portion of the first support member for rotation; A second support member having a thread support attached thereto, and a reciprocating motion applied to one end of the second support member in response to a swing displacement caused by a rotational displacement applied to the support shaft. The swing displacement of the second support member, which is generated with the swing support shaft as a fulcrum, is synthesized based on the displacement.

As a result, the swing displacement of the first support member to which the connecting thread proof is attached and the swing displacement of the second support member to which the front and rear ground thread proof is attached are effectively reduced. As a result, the swinging displacement of the front and rear ground thread proofs is independent of the swinging displacement of the connecting thread proofs. As a result, the swinging position of each guide thread proof can be easily adjusted, The amount of movement of the front and rear ground yarn proofs, that is, the swing width can be reduced.

Further, it is preferable that the two rows of needles are configured to swing in a direction opposite to the swing direction of the yarn guide. As a result, the amount of movement of the yarn guide is shared with the amount of swing of the twenty-one dollar row, so that the amount of swing can be reduced to the minimum, and as a result, the vibration of the knitting machine is effectively suppressed. This leads to an increase in the number of revolutions of the knitting machine.

On one of the front and rear cam shafts, for example, on the side of the front cam shaft 12a as shown in the figure, the support shaft 6 is rotationally displaced via the drive lever 10 to drive the first support member Ί. A cam lever 14a is provided in association with the cam 13a to be swung. On the other camshaft, for example, on the side of the rear camshaft 12b as shown in the figure, a cam 1 for driving and swinging and displacing the second support member 9 separately from the first support member 7 is provided. A cam lever 14b is provided in connection with 3b.

Accordingly, the swing of the front and rear ground yarns 5a and 5b synchronized with the swing of the connecting yarn 5c attached to the first support member 7 is different from this. The rocking displacement is generated and combined so that the rocking displacement independent of the rocking displacement of the connecting thread Pro 5c can be imparted to the front and rear ground thread pros 5a and 5b. Reference numeral 15a denotes a cam lever shaft that supports the front cam lever 14a, and 15b denotes a cam lever shaft that supports the rear cam lever 14b.

Reference numeral 19a denotes a shaft for supporting the arm 17a, which is provided rotatably through the intermediate frame 11a. The connecting portions of the cam lever 14a, the connecting rod 16a, the arm 17a, the driving rod 18a, and the driving lever 10 are connected to each other by a rotatable connecting structure. The connection position is provided so as to be adjustable with respect to the first support member 7 so that a desired rotational displacement can be generated in accordance with the distance between the hooks, that is, the distance between the front and rear trick plates 2a and 2b. Can be Therefore, connecting arms 20a, 2la and 22a for connecting the connecting port 16a and the driving port 18a to the arm 17a and the driving lever 10 are provided. Are provided in parallel. Normally, it is set so that a change of one of these connecting holes 20a, 21a and 22a can correspond to a change of about 2 mm between the trick plates 2a and 2b. Is done. Fine adjustment is also possible by combining these connection positions. In addition, the force lever 14a can be provided so that the connection position of the connection port 16a can be adjusted.

In FIG. 2 in which the distance between the front and rear trick plates 2a and 2b is increased from that in FIG. 1, the front connection port 16a, the arm 17a, and the drive port pad are provided. The connection position of 18a is changed.

The rear cam lever 14b is connected to a rotatably supported arm 17b via a connecting rod 16b, and rotates in synchronization with the arm 17b. The arm 17d provided on the same axis as

ί

One end (lower end) of the second support member 9 is connected to a rear extension end 9 a of the second support member 9 via a drive rod 18 b which is axially attached to one end (lower end) and extends upward. In conjunction with the rotation of the camshaft 12b, the second support member 9, that is, the front and rear ground thread proofs 5a and 5b swing about the swing support shaft 8 as a fulcrum. It is configured as follows. Reference numeral 19b denotes a shaft that supports the arms 17b and 17d, and is provided rotatably through the intermediate frame 11b.

The connection portions of the force lever 14b, the connection port 16b, the arms 17b, 17d, the drive port 18b, and the second support member 9 are mutually rotatable. Are connected by a simple connection structure. Further, the connection position is provided so as to be adjustable so that a desired swing about the swing support shaft can be generated with respect to the second support member 9. Therefore, for example, the connecting holes 20 b and 21 b for connecting the connection port 16 b and the drive port 18 b are respectively provided in the arms 17 b and 17 d. A plurality is provided in parallel. The force lever 14b can also be provided so that the connection position of the connection port 16b can be adjusted.

The cam shafts 12 a and 12 b at the front and rear portions include cam levers 14 a and 14 b for driving the first support member 7 and the second support member 9, etc. There are provided cam levers for driving the front and rear needle rows 1a and 1b, the trick plates 2a and 2b, and the front and rear stitch combs 3a and 3b, respectively, for rotating the camshaft. The resulting displacement of the cam lever is connected to the arms on the support shafts 4a and 4b via a drive member such as a rod lever. Since this point is not the gist of the present invention, the detailed illustration is omitted.

In response to the swing of the front and rear ground yarns 5a and 5b, which synchronize with the swing of the connecting thread Pro 5c attached to the first support member 7, another swing displacement is generated. A more detailed description will be given of a structure in which a means for generating and synthesizing is provided to impart a swing displacement independent of the swing displacement of the connecting thread Pro 5c to the front and rear ground thread Pros 5a and 5b. . As shown in FIGS. 3 and 4, the first support member 7 to which the connecting thread 5c is attached is fixed to the support shaft 6 from above and below. 71 indicates a fastening bolt for fixing. The swing support shaft 8 is fixed to the first support member 7, and ground yarn proofs 5 a and 5 b at the front and rear portions are attached to the swing support shaft 8 via the bearing members 23. The second support member 9 is swingably fitted and attached. One end of the second support member 9, that is, the rear end, is extended, and the drive port 18 b is connected to the extended end 9 a. Accordingly, the second support member 9 swings about the support shaft 6 together with the first support member 7 by the rotational displacement of the support shaft 6 that is interlocked with the rotation of the front cam shaft 12a. Simultaneously with this, separately from the above-mentioned movement, the reciprocating displacement of the drive port 18b interlocking with the rotation of the camshaft 12b allows the revolving shaft 8 to be swung about the fulcrum. It has become.

As a result, the swing of the front and rear ground yarns Pro 5a and 5b synchronized with the swing of the connecting yarn Pro 5c attached to the first support member 7 causes another swing. A dynamic displacement is generated and synthesized, so that the front and rear ground thread pros 5a and 5b are given a swing displacement independent of the swing displacement of the connecting thread Pro 5c. .

That is, a reciprocating displacement is applied to one end (extended end 9 a) 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. Oscillating displacement about the pivot shaft 8 is generated, and this oscillation is combined with the oscillating displacement about the supporting shaft 6, so that the front and rear ground thread proofs 5 a and 5 b can be formed. On the other hand, a swing displacement independent of the swing displacement of the connecting thread Pro 5c can be provided.

At this time, the camshaft 1 is arranged such that the swing displacement of the front and rear ground thread proofs 5a and 5b is smaller than the swing displacement of the connecting thread proof 5c. A predetermined reciprocal displacement is applied to one end of the support member 9 by the rotation of 2b. I can.

In other words, for the connecting thread 5c, the connecting thread is alternately applied to the needle rows la and 1b at the front and rear portions where the front and rear base fabrics are knitted. The larger the distance between the two, the larger the swing amount must be.However, for the front and rear ground yarns 5a and 5b, the front needle row 1a for knitting the front base fabric or the rear needle row Since it is only necessary to guide the yarn to the rear needle row 2b for knitting the base fabric, it is not necessary to make the amount of the axial displacement so large. Therefore, as described above, the swing displacement of the front and rear ground thread prizes 5a and 5b is set to be smaller than the swing displacement of the connecting thread pr 5c.

This will be described with reference to FIGS. Fig. 5 shows the state of knitting timing of the over-rubbing of the yarn proof with respect to the rear row of needles 1b when the distance between the trick plates 2a and 2b is 50 mm. This figure shows the state of knitting timing of the over-lapping of the leading thread with respect to the front twenty-one dollar row 1a.

In FIG. 5, the connecting thread proof 5c attached to the first support member is connected to the first support member attached to the support shaft that is pivotally displaced via the drive lever. At the same time, it is swung in the direction of the outline arrow A1 (the side of the rear needle row 1b) in the figure.

On the other hand, with respect to the front and rear ground yarn proofs 5a and 5b attached to the second support member, the second support member attached to the first support member via a swing support shaft. Swings in the direction of the outline arrow A1 together with the supporting member, but at the same time, another swing occurs around the swing supporting shaft with respect to the second supporting member. This is combined with the swing in the direction of the arrow A1, so that the swing displacement is suppressed as a whole, and the front ground thread pr 5a separates from the connecting thread pr 5c. As shown in the figure, and the back ground thread 5b is a connecting thread. It is displaced so as to approach 5p.

Further, in FIG. 6, the connecting thread pr 5 c attached to the first support member is, in contrast to the above, a hollow arrow A 2 in the figure together with the first support member around the support shaft. (The side of the front $ 21 row 1a).

On the other hand, the front and rear ground yarn proofs 5a and 5b attached to the second support member are pivoted in the direction of the outline arrow A2 together with the second support member. However, at the same time, another swing occurs around the swing support shaft with respect to the second support member, particularly in the opposite direction to the case of FIG. As a result, the rocking displacement is suppressed as a whole, and the front ground thread Pro 5a is displaced closer to the connecting thread Pro 5c, and the rear The ground thread proof 5b is displaced away from the connecting thread proof 5c.

That is, while the connecting thread pr 5c is oscillatingly displaced between the front and rear 21 dollar rows la and 1b, the swing deflecting of the front and rear ground thread pr 5a and 5b is performed. The position has a small swing width. The swing position due to this swing displacement, that is, the position of action on the needle row, is determined by the swing amount of the first support member 7, the attachment position of the connecting thread Pr 5 c to the support member 7, and the second position. By adjusting the amount of swing of the support member 9 and the attachment position of the front and rear ground threads 5a and 5b with respect to the support member 9, the swing position of the ground threads 5a and 5b is adjusted. Can be easily adjusted.

It should be noted that, even when the distance between the trick plates 2a and 2b in FIG. 1 is 24 mm, it is basically the same as described above. In addition, the swing width due to the swing displacement of the ground thread proofs 5a and 5b at the front and rear portions is reduced. However, the difference between the swing width of the connecting thread Pro 5c and the swing width of the front and rear ground thread Pro 5a and 5b is small. In particular, in actual knitting, the front and rear needle rows 1a and 1b and the trick plates 2a and 2b are also basically used for the ground yarns 5a and 5b for the front and rear portions and the connecting yarns. Since the swing direction of each of the yarns Pro such as Pro 5c swings in the direction opposite to the swing direction of the proto 5c, the amount of movement (the swing width) of the ground yarn Pro 5a and 5b and the connecting yarn Pro 5c is determined. ) Is even smaller. Normally, this is about one-half of the case where the $ 21 row is not rocking.

The diagram in FIG. 7 shows the vertical movement of the front and rear needle rows la and lb when the distance between the torque plates 2a and 2b is 24 mm, and the ground thread proofs 5a, 5b and 5 shows the swinging motion of the connecting thread Pro 5c. Furthermore, the diagram of Figure 8, the Application Benefits Kkupureto 2 a ₃ 2 spacing between b is about cases of 5 0 mm, the front and rear needle rows la, the lifting movement of the lb, ground yarn for Pr 5 a, 5b and the swing motion of the connecting thread Pr 5c.

According to these two diagrams, the swing width of the front and rear ground thread proofs 5a and 5b is smaller than the swing width of the connecting thread proof 5c, and in particular, between the torque plates 2a and 2b. The larger the interval, the smaller the swing width of the front and rear ground thread proofs 5a and 5b with respect to the swing width of the connecting thread proof 5c, and the difference between the swing widths is larger. .

That is, the greater the distance between the trick plates 2a and 2b, that is, the greater the thickness of the knitted double-sided warp knitted fabric, the greater the effect of employing the device of the present invention.

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

[Possibility of industrial use]

The present invention provides a drive mechanism for the driving motion of the yarn guide pr in a double Raschel machine for knitting a two-sided warp knitted fabric. It is particularly suitable for use in a double shell machine that requires a change in the swing width of the yarn guide according to the size of the thickness between the front and rear base cloths, the spacing between the front and rear 21 dollar rows and the knitting structure. .
