Description

[Detailed explanation of the idea] The present invention relates to a conductive liquid drive device for a warp knitting machine.

Conventionally, in warp knitting machines, the amount of displacement of the conductive liquid used to guide the knitting yarn to the knitting needles has been set using pattern setting devices such as pattern chain links or pattern chains. Long patterns require a large number of pattern chains, require a large space to equip a warp knitting machine, and require a great deal of effort.

Therefore, recently, instead of the pattern chain, a device has been proposed that converts the step rotation amount by an electric signal such as a rotary pulse motor into linear momentum, and then controls the displacement amount of the conductive liquid via a transmission member. .

However, in the above device, various devices such as a pin drum and a ball screw are required as intermediate devices between the conductive liquid and the rotating pulse motor to convert the step rotation amount into linear momentum, and as a result, the back-up is increased. Although lash and other displacement errors are corrected, a separate device for correction is required, which is considerably disadvantageous compared to conventional devices in terms of cost and space.

The present invention aims to eliminate the above-mentioned drawbacks and provide a reed drive device that is simple and inexpensive, and does not require consideration of correction.

Next, an embodiment of the device of the present invention will be explained with reference to the drawings. Fig. 1 is a schematic side view of an embodiment of a conductive liquid drive device for a warp knitting machine, in which 1 is a conductive liquid and the conductive liquid 1 is a plate frame. 2, a plurality of U-shaped sliders 3 fixed to the upper side of the printing frame 2, and a thread guide rod 4 screwed to the bottom, so as to perform reciprocating motion in the direction of the five rows of knitting needles. , knitting needle 5
The same number of sliding receivers 6 as the sliders 3 are fixedly provided on the top.
held on top.

7 is a linear pulse motor, 8 is a guide member, 9 is a scale, 10 is a slider, and 11 to 14 are rollers. The slider 10 is configured to be able to reciprocate within the space formed by the member 8 and the scale 9.

15 is a connecting rod, 16.17 is a universal joint, and the universal joints 16 or 17 are connected to both ends of the connecting rod 15 to constitute a transmission member.
and a linear pulse motor 7, which are connected with pins or the like so that they can be attached and detached at any time.

18 is a pulse distributor, 19 is a controller, and 20 is a pattern storage medium.

To explain the operation of the embodiment device configured as described above, the motion command from the known control means, that is, the pattern storage medium 20 is sent to the controller 19, and the pulse signal from the pulse distributor 18 is sent to the linear pulse motor 7. By inputting the input, the slider 10 is excited by the required amount of pulses, and as a result is moved on the scale 9 via the rollers 11 to 14, and at the same time, the conductive liquid 1 is moved to the desired position accurately and quickly by the transmission member 15. Ru.

In this way, the amount of movement of the slider 10 of the linear pulse motor 7 can be directly transmitted to the conductive liquid 1 via the transmission member 15, which simplifies the configuration, and also allows the conductive liquid to be returned by spring force as in the conventional case. This eliminates the need for
As a result of no extra force acting on the sliding part of the conductive liquid such as the sliding receiver, there is no need for a structure that requires unnecessary strength maintenance, cost reduction can be achieved, and the durability of the sliding part can be improved.

Next, what is shown in FIG. 2 is another implementation device, and is an example in which two linear pulse motors 7, 70 are used for one conductive liquid 1, 90 is a scale, 100 is a slider, The guide member 8 and the scale 9, which are integrally configured, are fixed to the upper part of the slider 100 by a connecting rod 21, and the slider 100 receives a movement command from the same path as in the previous embodiment, and moves the upper rollers 110, 120 of the scale 90.
At the same time, the guide member 8 and scale 9 move through rollers 22 to 25 that are rotatably supported on the machine frame, and at the same time, a motion command is also given to the linear pulse motor 7. As a result, the slider 10 also moves as in the previous embodiment.

In the above embodiment, by using two linear pulse motors together, it is possible to dramatically increase the amount of conductive liquid movement in a short time when forming a single train. Since it is possible to reduce the number of parts that have conventionally been moved in two or more parts, the pattern has a good appearance.

Furthermore, when conventionally using conductive liquid as a floating pattern, a separate device was required for the movement of winding it around the knitting needles, but by using the device of this embodiment, it is possible to knit without the need for a separate device, which is advantageous. It is.

Note that in this embodiment, two pieces are used in combination, but of course it is also effective to use three or more pieces.

Further, another embodiment will be described with reference to FIG. 3. In this embodiment, the shock lever 26, the connecting rod 15, and the connecting rod 150 provided between the conductive liquid 1 and the linear pulse motor 7 are connected to the linear pulse motor 7. It serves as a transmission member that transmits motion to the conductive liquid 1.

The shog lever 26 is rotatably provided around a support shaft 27, and the distance between the support shaft 27 and the universal joint 170 at the end of the connecting rod 15, and the distance between the support shaft 27 and the universal joint 16 at the end of the connecting rod 150 are determined.
The distance ratio of 0 is 2:1, so if the amount of movement of the linear pulse motor 7 is a, the amount of movement transmitted from the connecting rod 15 to the connecting rod 150 via the shog lever 26 is 1/2a, This amount of movement is given as the movement of the conductive liquid.

In this embodiment, the amount of movement of the linear pulse motor 7 can be reduced to 1/2 and transmitted to the conductive liquid 1.

Therefore, even if there is an unavoidable error in the amount of movement of the linear purse motor 7, that error is reduced to 1/2, making it effective for controlling conductive liquid in knitting machines with fine gauges. .

As described above, the present invention uses a linear pulse motor as a movement source of the conductive liquid in a warp knitting machine that performs knitting by reciprocating the conductive liquid at least in the direction of the knitting needle rows, and uses the linear pulse motor as the movement source of the conductive liquid. Since the transmission member for transmitting the linear reciprocating motion of the pulse motor to the conductive liquid is detachably connected to the thread guide plate side and the linear pulse motor side, there is no need for conventional means such as springs. Since the conductive liquid can be made into a lightweight and simple structure, it is advantageous for providing multiple rows of the conductive liquid, and since there is no extra load on the conductive liquid, smooth knitting can be carried out. Since the reciprocating linear motion of the electrically conductive liquid can be directly converted into the reciprocating motion of the conductive liquid, the device itself can be simplified and the installation space can be reduced, resulting in many practical effects.
