Description Trick plate interval changing device in double lashing machine

[Technical field] The present invention relates to a trick plate interval changing device in a double lashing machine.

(Background technology)

Conventionally, in a double Raschel machine equipped with two rows of knitting needles before and after, when changing the thickness of the fabric to be knitted, it is necessary to change the distance between the opposing front and rear knitting needle rows. It was necessary to change the distance between the trick plates.

As a device for changing the distance between the front and rear trick plates, the present applicant has proposed and filed Japanese Patent Application No. 2000-800545. In this device, an eccentric mechanism provided with a hook means is connected to one end of each connection port connected to each support lever supporting the front and rear opposite trick plates, and a trick plate is provided. When the interval is changed, the buckle is released, and the connecting rod is displaced by turning the handle attached to the eccentric mechanism. The trick plate is displaced. By this operation, a desired trick plate interval can be obtained.

However, when the interval of the trick plate is changed by the above-mentioned proposed device, the trick plate turns around the axis of the supporting lever and is displaced, so that the tip of the trick plate becomes the tip of the knitting needle. Part However, a slight shift will occur in the lock direction. If this is left unchecked, the loop break-out conditions during knitting will change and hinder knitting. To correct this, adjust the stroke of the knitting needle after changing the trick plate interval. However, it was necessary to make changes, which complicated the work of changing the trick plate interval.

The present invention solves the above-mentioned problems in the double Raschel machine, makes it possible to easily change the trick plate interval, and eliminates the need for adjusting the stroke of the knitting needle after the change. It is an object of the present invention to provide a work plate interval changing device.

The flat panel 30 is held between the bottom surface of the concave portion and the flange member 31 by fitting into the concave portion on the upper surface side of the material 27. The other end (lower end) of the shaft portion 32 is slidably penetrated through a longitudinal hole 43 formed in the base machine base 6 in the front-rear direction. The nut 33 is engaged with the bottom surface 6a of the base machine base 6 directly or via a washer as shown in the figure, so that the front machine base 5a is Machine base 6 is tightly fixed. Incidentally, in the case of the present embodiment, a force of 1.8 t (ton) acts on one clamping means.

Note that the clamp means of the rear machine base 5b has substantially the same configuration as described above, and a detailed description thereof will be omitted here.

The means for tightening and loosening the clamp means will be described. A pipe 34 communicating with the internal space 27a of the cylinder member 27 of the clamping means is provided. As shown in FIG. 2, the piping 34 is provided so as to communicate with the six cylinder members 27 of the front machine base 5a, and is further connected to the rear machine body 5 by the communication pipe 44. It is also in communication with the six cylinder members 27 in b. Reference numeral 35 denotes a hydraulic jack, which is provided close to the machine base 6 and is connected to one end of a pipe 34 so as to be able to supply oil into the internal space 27a of each cylinder member 27. The biston member 29 and its shaft portion 32 can be moved against the expanding force (elastic force) of the counter panel 30 by the oil pressure due to the oiling action. That is, the front machine 5a and the rear machine 5b are clamped to the base machine 6 by the clamp means so as to be loosened by the hydraulic means. In FIG. 5, the pipe 34 is omitted.

The configuration of the embodiment of the trick-print interval changing apparatus according to the present invention has been described above. Next, the operation thereof will be described.

Reference numeral 36 shown in FIG. 1 indicates a solid knitted fabric being knitted, As described above, the knitting yarn supplied from the knitting group 37 arranged above the knitting needles la and 1b has a constant thickness (determined by the interval between the trick plates 2a and 2b). Is knitted.

If it becomes necessary to change the thickness, first, the lever 35a of the hydraulic jack 35 is actuated so that the oil is supplied to the piston member 29 of the internal space 27a of each cylinder member 27. Press into the upper part of. As a result, the biston member 29 and its shaft 32 move in the direction of the arrow 38 in FIG. 5 against the enclosing force (elastic force) of the flat panel 30. As a result, a slight gap is formed between the bottom surface 6a of the base machine base 6 and the engaging portion of the double nut 33, that is, the washer or the like (0.4 mm in the case of the embodiment).

As a result, the pressure-fixed state of the front machine 5a and the rear machine 5b with respect to the base machine 6 is released. Then, by sending a drive signal to the motor 22, the shaft 23 passes through the sprocket 24, the connecting chain 25, and the sprocket 21 to move the left and right knitting machines on the transmission shaft 18. Both worms 16 rotate, and furthermore, both screw shafts 12, 12 on the left and right sides of the knitting machine are simultaneously rotated via both worm wheels 15, 15.

If it is desired to increase the width of the trick plates 2a and 2b beyond the current distance, the transmission shaft 18 is rotated counterclockwise when viewed from the motor 22 side, so that the front machine can be used. The platform 5a moves forward and the rear machine 5b moves rearward in a straight line. At this time, of course, the intermediate frames 4a and 4b, the bearing shafts 7a and 7b, the holders 3a and 3b, the trick plates 2a and 2b, and the knitting needles la and 1b They will be separated by the same distance as they move. Therefore, the relative relationship between the knitting needle 1a with respect to the trick plate 2a and the knitting needle 1b with respect to the trick plate 2b does not change. Therefore, it is not necessary to adjust the stroke of each of the knitting needles 1a and 1b when changing the distance between the trick plates 2a and 2b. When the above-mentioned trick plates 2a and 2b are made narrower than the current distance, by rotating the transmission shaft 18 clockwise in the opposite manner to the above, the front machine base 5a becomes the rear machine. Move linearly in the direction approaching the platform 5b. After the above movement adjustment, the oil supply into the internal space 27a of each cylinder member 27 is released, so that the piston member 29 and its shaft portion 32 expand the flat panel 30. The force is restored to the original state, and the front machine 5a and the rear machine 5 are kept fixed to the pace machine 6, respectively.

A plurality of winding rolls are arranged below the knitting part formed by the knitting needle rows in parallel in the width direction of the knitting machine (perpendicular to the plane of FIG. 1). The located first winding roll 39 is disposed so as to face the pressing roll 40. In this case, one of the first winding roll 39 and the pressing roll 40 facing each other, for example, as shown in the figure, the first winding roll 39 is located on the front intermediate frame 4a, and the other is located on the other side. For example, if the holding holes 40 are integrally provided on the rear intermediate frame 4b, the front machine 5a and the rear machine 5b move away from each other by the same distance. Or, even if the interval between the trick plates 2a and 2b is changed, the roll interval that matches the thickness of the three-dimensional knitted fabric 36 to be knitted is automatically determined. .

In this embodiment, the motor is used to change the trick plate interval. However, the driving means is not limited to the motor and other driving means, for example, a handle may be attached to the transmission shaft. However, it is needless to say that the operation can be performed by manually turning the handle.

As described above, according to the apparatus for changing the interval of the trick plate of the present invention, the front and rear machine bases 5a and 5b supporting the front and rear trick plates 2a and 2b are respectively provided. However, since they are separated or approached linearly by the moving means, the outlets of the knitting needles 1a and 1b with respect to the trick plate —The relative position does not change before and after the change. Therefore, it is not necessary to adjust the stroke of the knitting needle after changing the trick plate interval.

Further, the moving means is a screw shaft 12 which is screwed through the front machine base 5a and the rear machine frame 5b in the front-rear direction. Preferably, one side of the screw shaft 12 is a right-hand screw. In addition, by using a left-hand screw on the other side, the configuration is simplified, and driving can be facilitated.

In addition, the change work can be simplified by hydraulically fixing the front machine base 5a and the rear machine base 5b to the base machine base 6 by crimping and releasing from the fixing.
