Description

[Detailed description of the invention] The present invention relates to a knitting switching device for a knitting machine.

In each stage of knitting while the knitting machine is in use, outside the line width of the knitted material, knitting needles that do not participate in knitting should be pushed down to a lowered position where they do not come into contact with the cam of the carriage so that they are out of the knitting action of the cam of the carriage. Up to two techniques have been proposed to carry out molding.

However, if the knitting needles are constructed so that they can be lowered to a lowered position beyond the action of the knitting cams, there is a risk that the knitting needles may sink due to the impact during knitting, causing problems in knitting.

The purpose of the present invention is, firstly, to meet the above-mentioned problems.
The knitting needles remain in their normal non-sinking position where they receive the action of the knitting cam, and at both ends of the forming, the knitting needles within the wire width are placed in the knitting path where they are subjected to the cam action, and the wire width outside the wire width is unknitted. The first purpose is to provide a technology for forming by switching to guide the needle to the passage, and the major feature of this means is that it has a pair of left and right wedge cam-like cam grooves on the needle bed side, the position of which can be adjusted. A positioner (hereinafter referred to as a forming instruction member) is provided, and this is set at a position corresponding to both ends of the wire width to be formed, and a positioner is provided on the carriage side that engages with the forming instruction member at the set position. Means for producing the passage switching action is provided through a mechanism that performs a reversal operation.

Furthermore, in the present invention, in setting the position of the forming instruction member that gives the above-mentioned forming, this is used in combination with a knitting type indicator, and an instruction reading mechanism and a forming instruction member are used in combination with the knitting type display indicator. Another object is to provide a technique that makes it easier to form according to knitting pattern indications by means of interlocking the setting mechanism.

A main chain gear 64 (64/) for moving the moving belt 59 (59) is fixed, and a driven chain gear 65 (65') supporting the moving belt 59 (57) is rotatably supported, and the transmission is transmitted downward. Fix the gear 66 for use.

Therefore, by rotating the rotation shaft 60.61, the right and left signal reading members 56.58 are moved.

Note that the manual knobs 62 and 63 are used to adjust the signal reading members 56, 58 and the molding instruction members 24, 25 so that they point to the same reference position.

The rotating shaft 60.61 is interlocked with the shaft 14.15 through a variable movement mechanism.

That is, 67.degree. 68 is a shaft pivotally supported by the substrate P, and fixes the gear 69 meshing with the gear 20 and the conical wheels 70 and 70'.

71.72 is a shaft pivoted on U-shaped frames 73, 74 that are pivoted on the rotating shaft 60.61, gears 71a, 72a meshing with the gear 66 are fixed to one end, and the small wheels 75.76 are attached to the shafts 71, 72. axis 71
, 72 so as to be movable only in the longitudinal direction, and a spring 77 always presses the small wheels 75, 76 against the conical wheels 70, 70'.

The press-contact state is caused by the protrusion 7 on the upper side of the U-shaped frames 73 and 74.
By operating 3a and 74a, they can be separated against the spring 77.

78.78' is the conical wheel 70.70' with the small wheels 75°76
This is a changing member for changing the pressure contact position, and the pressure contact position can be changed by rotating the shafts 79 and 80 using knobs 81 and 82.

Therefore, by appropriately setting the relative dimensions of these variable movement mechanisms, the positions read by the left and right signal reading members 56 and 58 are enlarged (or reduced) and the corresponding knitting needles are selected by the left and right forming instruction members 24 and 25. can give instructions.

The overall operation of the configuration as described above will be explained below.

First, the feed amount changing device 54 is operated according to the stitch gauge to set the feed amount of the signal display member 52, and the U-shaped frame 73,
74 against the spring 77, the small wheel 75.76 is separated from the conical wheel 70.70', the knob 81.82 is rotated, and the small wheel 75.76 is pressed into position. change.

Next, the signal reading member 56.58 and the forming instruction member 24.2
Rotate and adjust the manual knobs 62 and 63 so that both numbers 5 and 5 indicate the reference position.

Next, if the knob 16.17 is rotated so that the signal reading members 56, 58 match the pattern 51 of the knitted product, the endless belt 22.23 is rotated via the main drive chain gear 18.18'. The forming instruction members 24 and 25 move, and the gears 20, 69,
The conical wheel 70.70' is rotated through the shaft 67.68, and the small wheel 75.76 is rotated to connect the shaft 71.72 and the gears 71a, 7.
2a and 66, the signal reading member 56.58 is moved via the main drive chain gear 64.64' and the moving belt 57.59, and the axis of the knob 16 and 17 is rotated. 14 and 15 rotate, the main chain gear 18,
18', forming instruction member 2 via endless belt 22, 23
4.25 moves, the position of the pattern 51 of the knitted product read by the signal reading member 56.58 is converted according to the stitch gauge, and the corresponding knitting needle can be indicated by the forming instruction member 24.25, and the position is determined by the spring 21. is maintained by

(However, in the case of implementation without using the formation instruction device 50,
(In the above procedure, irrelevant parts are unnecessary.) Next, the knitting needles 2 necessary for knitting (knitting needles in section T in Figure 1, as long as they are larger than the maximum width of the knitted product) are aligned and arranged at the knitting waiting position (position B). and move the switching pin 43°43' to the rear position (
4), and the raising cam 28 is placed in the open position (as shown by the two-dot chain line in FIG. 4).

It is assumed that the molding instruction members 24, 25 are arranged at the first illustrated position.

In this state, if the carriage 7 is moved rightward in FIG. 4 (the same effect occurs when moving leftward, only the rightward movement will be described).

), among the knitting needles 2 (knitting needles in section T in FIG. 1) at the knitting standby position (position B), the knitting needles 2 in section U in FIG. Molding instruction member 2
5, the forward cam 25a moves it to the forward position (shown in solid line in FIG. 4), and the raising cam 28 is placed in the closed position (shown in solid line in FIG. 4).

Therefore, the knitting needles in section S in FIG. 1 are introduced into knitting path B-C and knitted.

As the carriage 7 further advances, the switching pin 43 reaches the position of the forming instruction member 24, and is moved to the rear position (
4), and the raising cam 28 is placed in the open position (as shown by the two-dot chain line in Figure 4), so that the knitting needles in the section of Figure 1 are introduced into the passing path B-B and are not knitted. .

Therefore, only the knitting needles in section S in FIG. 1 can be knitted.

Next, the signal reading members 56, 58 are shown by the two-dot chain line 56a in FIG.
, 58a, when specifying a curved portion 51a where the number of stitches decreases, turn the manual knob 16°17 and move the signal reading member 56°58 as described above to match the curved portion 51a. Indicating members 24, 25 indicate the corresponding knitting needle.

Therefore, when the carriage 7 is moved next time, the knitting needles of only this section (section S' in FIG. 1) are knitted in the same manner as described above.

If knitted in this way, it can be molded.

Furthermore, by replacing the raising cams 28, 28', which are the switching cams, with switching cams that open and close passages for other stitches, it becomes possible to automatically change the pattern width of a partial stitch.

Since the present invention is constructed as described above, unlike the prior art in which the knitting needles, which are not involved in the knitting operation, are pushed down and retracted to the lowered position where the knitting cam does not act, the knitting needles may be damaged by the impact during knitting. There is no possibility that the particles will settle and interfere with the formation.

Then, according to the signal from the signal display member that indicates the signal related to knitting, the instruction member is moved in the longitudinal direction of the needle bed (the direction in which the knitting needles are arranged).
By moving the switching cam on the carriage, the switching cam on the carriage can be switched, and the knitted fabric can be formed by simply adjusting the signal reading member to the signal, so it is easy to handle.

Furthermore, it can be conveniently used to automatically change the width of a partial pattern.
