Description

TRICK PLATE SPACING CHANGER FOR DOUBLE RASCHEL MACHINES}

Conventionally, in a double-shell machine having two rows of single-sided stitches, when changing the thickness of the dough to be knitted, it is necessary to change the spacing between the front and rear side of the single-sided stitches. There was a need.

As an apparatus for changing the distance between the front and rear trick plates, the present applicant has proposed and filed Japanese Patent Laid-Open No. 2000-80545. The device connects the eccentric mechanism provided with the locking means to one end of each connecting rod connected to each supporting lever supporting the opposite and opposite trick plates before and after, and releases the locking means at the time of changing the trick plate interval, The connecting rod is displaced by turning the handle attached to the eccentric mechanism, thereby rotating the support lever so as to displace the trick plate supported at the tip. By this operation, a desired trick plate spacing is obtained.

However, in changing the distance of the trick plate by the proposed device, since the trick plate is displaced by turning about the support lever shaft, the tip portion of the trick plate causes a slight deviation in the stroke direction with respect to the tip portion of the knitting needle. If this is left unchanged, the condition of detachment of the loop at the time of knitting is changed, and this causes a problem in knitting. Therefore, by correcting this, the stroke adjustment and change of the knitting needle are inevitable after changing the trick plate interval. This made it complicated to change the trick plate spacing.

The present invention provides a trick plate spacing changing device which can simplify the work of changing the trick plate spacing by eliminating the above-mentioned problem in the double-shell machine and also make it unnecessary to adjust the stroke of the needle after the change work. It aims to do it.

The present invention relates to a trick plate spacing changing device in a double sheller.

The trick plate spacing changing device of the present invention which solves the above-mentioned problems supports knitting needles in two rows before and after, before and after trick plates attached to both knitting needles, and before and after knitting needles and trick plates. In the double-shell system consisting of a front and rear intermediate frame, and each front and rear intermediate frame is a granular fixed front machine pedestal and rear machine base, the front machine rear and rear machine base are separated and proximate linearly. It is characterized in that the moving means to be installed on both machine pedestals, the interval between the front and rear trick plate can be changed together with the partial needle heat.

According to the distance changing device of the trick plate of the present invention, the front and rear trickle distances can be easily changed by separating or adjoining the front and rear machine stands in a straight line by the moving means. In addition, as a result of the same parallel movement of all parts on the front and rear machine base including the front and rear trick plates and the front and rear knitting needles, the relative positions of the trick plate and the hands are not changed before and after the change, so that the stroke adjustment of the hands is unnecessary. Become.

In addition, the front and rear trick plates are attached to the support shaft which penetrates in the knitting width direction the plurality of intermediate frames, respectively, which are granularly fixed to the front and rear machine support, respectively, and are installed to enable knitting operation together with the knitting needle.

More preferably, one side of the screw shaft is a right screw and the other side is a left screw. As a result, the configuration can be simplified, and driving can be facilitated.

In addition, the above-mentioned front machine base and the rear machine base are fastened to the base machine base by clamping means, respectively, and fastening and loosening of the front machine base and the rear machine base can be performed by hydraulic means. Thereby, fixing to the base machine base of the member around the machine base containing a trick plate, and the release for the movement can be performed easily, and a change operation is simplified.

In addition, by performing the rotation of the screw shaft with a motor, the desired work can be performed in a short time without requiring effort.

Further, a first winding roll and a suppression roll are disposed to face each other in parallel to the lower side of the knitting portion due to the partial needle heat, and one of the first winding roll and the suppression roll is the front middle frame, and the other is the rear middle frame. In the case where the trick plate spacing is changed, the spacing between the opposite rolls corresponding to the thickness of the three-dimensional warp knitted fabric to be knitted is automatically determined.

Regarding the clamp portion, since the knitting machine movable width is 75 inches in the double-shell machine of the present embodiment, as shown in FIG. 2, three pairs of clamp portions, each of which are two pairs, are respectively used for the front and rear machine supports 5a and 5b (6). It is, of course, installed, but of course, the number of clamp portions can be increased or decreased by increasing or decreasing the knitting width of the knitting machine.

The structure of the said clamp means is demonstrated based on FIG. 2, FIG. 4, FIG. 4 is a cross-sectional view taken along the line B-B in FIG. 2. In Fig. 4, since the configuration of the left and right clamp means is the same, only the clamp means on the left side of the drawing will be described.

In the figure, "27" is a cylinder member screwed to the front machine support 5a by four bolts 28, and "29" is sliding up and down in the inner space 27a of the cylinder member 27. It is a piston member provided so that the axial part 32 of the said piston member 29 penetrates the cylinder member 27 and the front machine base 5a up and down. "30" is a disc spring and is fitted to the thin diameter portion of the flange member 31, and the flange member 31 is fitted to one end (upper end) of the shaft portion 32 of the piston member 29 to be fixed. have. The flange member 31 fits into an upper surface side recess of the cylinder member 27, and the disc spring 30 is held between the bottom face of the recess and the flange member 31. The other end (lower end) of the shaft portion 32 slidably penetrates the longitudinal hole 43 in the front-rear direction formed in the base machine pedestal 6, and at the end, a double nut 33 is directly or as shown in the figure. It is engaged with the bottom face 6a of the base machine base 6 via the washer, and for this reason, the front machine base 5a and the base machine base 6 are strongly fixed and fixed by the said disc spring 30. As shown in FIG. In other words, in the present embodiment, a force of 1.8 t (ton) per clamp means is applied.

In addition, since the clamp means of the rear machine base 5b has comprised substantially the same structure as the above, detailed description is abbreviate | omitted here.

Means for tightening and loosening the clamp means will be described.

A pipe 34 passing through the internal space 27a of the cylinder member 27 of the clamp means is provided. As shown in Fig. 2, the pipe 34 is provided in communication with the six cylinder members 27 of the front machine pedestal 5a, and the rear machine pedestal 5b is provided by the connecting pipe 44. The six cylinder members 27 are also in communication with each other. &Quot; 35 " is a hydraulic jackie, is provided close to the machine support 6, and is connected to one end of the pipe 34 so as to enable oil supply in the internal space 27a of each cylinder member 27. It is comprised so that the said piston member 29 and its shaft part 32 may be moved and moved with the expansion force (elastic force) of the said disc spring 30 by the hydraulic force by an action. That is, the hydraulic means is provided to tighten and loosen the front machine base 5a and the rear machine base 5b to the base machine base 6 by the clamp means. 5, the pipe 34 is omitted.

Although the above is the structure of one Example in the trick plate space changing apparatus of this invention, the operation | movement is demonstrated next.

Reference numeral “36” shown in FIG. 1 denotes a three-dimensional warp knit in knitting, and as is well known, a certain thickness (trick plate) is provided by the knitting yarn supplied from the knitting body group 37 disposed above the knitting needles 1a and 1b. Letters determined by the intervals of (2a, 2b) are organized.

In the case where the need to change the thickness occurs, first, by operating the lever 35a of the hydraulic jack 35, the working fluid is moved to the upper side of the piston member 29 of the internal space 27a of each cylinder member 27. Indent As a result, the piston member 29 and its shaft portion 32 move in the direction of the arrow 38 in FIG. 5 against the expansion force (elastic force) of the disc spring 30. As a result, a slight gap occurs between the bottom face 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 embodiment).

However, the crimp fixed state of the front machine base 5a and the rear machine base 5b with respect to the base machine base 6 is released. Then, by sending a drive signal to the motor 22, both worms left and right of the knitting machine on the transmission shaft 18 through the sprocket 24, the connection chain 25, the sprocket 21 from the shaft 23 ( 16) rotates, and both screw shafts 12 on the left and right sides of the knitting machine are simultaneously rotated through both worm wheels 15.

Now, when the trick plates 2a and 2b are to be made wider than the current interval, the front machine pedestal 5a is moved to the front side by rotating the transmission shaft 18 counterclockwise from the motor 22 side. The pedestal 5b moves in a state of being spaced apart in a straight line to the rear side. At this time, of course, the intermediate frames 4a and 4b, the support shafts 7a and 7b, the holders 3a and 3b, the trick plates 2a and 2b and the knitting needles 1a and 1b also move their respective machine stands. Depending on the distance will be separated. Therefore, there is no change in the relative relationship between the knitting needle 1a for the trick plate 2a and the knitting needle 1b for the trick plate 2b. Therefore, it is not necessary to adjust the stroke of each knitting needle 1a, 1b at the time of changing the space of the trick plates 2a, 2b.

In addition, when the trick plates 2a and 2b are narrower than the current gap, when the electric shaft 18 is rotated clockwise in contrast to the above, the front machine base 5a approaches the rear machine base 5b. In linear direction. In addition, after releasing oil supply to each of the cylinder members 27 into the internal space 27a, the piston member 29 and the shaft portion 32 of the cylinder member 27 are released by the extension force of the disc spring 30. It returns to the state of, and the front machine stand 5a and the rear machine stand 5b are respectively fixed to the base machine stand 6.

In addition, a plurality of winding rolls are arranged in parallel in the knitting width direction (vertical direction with respect to the paper surface of FIG. 1) below the knitting portion by the knitting heat, and among these, the first winding roll 39 located at the knitting portion side. Are arranged opposite to the suppression roll 40. In this case, one of the first winding roll 39 and the suppression roll 40 facing each other, for example, the first winding roll 39 as shown in the drawing, is different from the front intermediate frame 4a. For example, if the suppressor rollers 40 are integrally provided in the rear intermediate frame 4b, respectively, they are separated by the same distance by the movement of the front machine support 5a and the rear machine support 5b, respectively. Or because it comes close, even if the space | interval of the trick plates 2a and 2b changes, the roll space | interval suitable for the thickness of the three-dimensional warp knitted fabric 36 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, but is carried out by attaching another driving means, for example, a handle to the electric shaft and manually rotating the handle. Of course it is possible.

As described above, according to the distance changing device of the trick plate of the present invention, each of the front and rear machine pedestals 5a and 5b supporting the front and rear trick plates 2a and 2b are linear by moving means. Since they are spaced apart or close to each other, the stroke relative positions of the needles 1a and 1b with respect to the trick plate are not changed before or after the change. Therefore, the single needle stroke adjustment after the trick plate interval change is unnecessary.

Moreover, the said moving means is made into the screw shaft 12 which consists of screwing in the front-back direction with respect to the front machine base 5a and the rear machine base 5b, Preferably one side of the screw shaft 12 is a right-hand thread. By using the other side as the left screw, the configuration can be simplified and the driving can be facilitated.

In addition, the modification work is simplified by carrying out the crimping fixing of the front machine base 5a and the rear machine base 5b to the base machine base 6 and opening from the fixing by hydraulic means.

In the present invention, in a double-shell machine having two rows of single-sided stitches, it is necessary to change the interval of the front-side single-sided fever and change the space of the front-back trick plate accompanying the single-handed needle when changing the thickness of the knitted fabric. It is especially preferable to use.
