Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for displaying needles at both ends of a line width in each knitting stage of a hand knitting machine with numbers corresponding to the respective needles.

In particular, the present invention enables the user to judge the increase or decrease of stitches by comparing the stitches obtained by knit 1 laser or indexing calculation with the numerical display of the end needle.

Traditionally, to know which stitches are being knitted, you read the numbers written near the knitting needles at both the left and right ends, but the numbers written are every 10th needle, and the numbers in between are only line indications. It was difficult to read the direct number.

Since the present invention displays numbers in easy-to-see locations, it is very easy to confirm the number of stitches.

In particular, since the left and right line widths are indicated with respect to the reference knitting needle, it is easy to see the correspondence with the stitch scale of the knit tracer.

Examples will be described below with reference to the figures.

FIG. 1 shows a sectional view of a household knitting machine constituting the present invention.

A plurality of knitting needles 2 are arranged in rows on a needle bed 1 so as to be movable up and down and back and forth.

When the lowering cam 42 is in the O state, it passes through the passage shown by the solid line e2, and the lowering cam 5
does not pass through.

When the butt of the knitting needle 2 is located at position A, it passes through the path shown by the solid line a and does not pass through the lowering cam 5.

Therefore, what passes through the knitting cam 41 also passes through the rolling down cam 5, and what does not pass through the knitting cam 41 does not pass through the rolling down cam 5.

Further, the knitting needles 2 passing through the lowering cam 5 are lowered downward as shown in FIG.

Eight pattern plates G1 to G8 and five search plates 1 to 5 are attached to a plate support member 7 so as to cross the knitting needles 2.

The pattern plates G1 to G8 are always biased to the left in the figure by a spring (not shown).

When the knitting needle 2 is pressed down, the knitting needle 2 is pushed down by the first cam surface 21.
The pattern plate corresponding to the number moves to the right in the figure.

As shown in FIG. 6, small holes CH1 to G8 are provided in the pattern plates G1 to G8, which are held on the plate support plate 7 so as to be horizontally movable by the plate support rod 8, so that the pattern plates move to the right in the figure. If so, switch G via levers GL1 to GL8.
S1 to GS8 are operated to produce the input signal for the electronic circuit shown in FIG.

On the other hand, protrusions 30 are provided on the retrieval board 1 to 5 in correspondence with each block in which needle numbers 1 to 8 of the knitting needles 2 constitute one block, as shown in FIG.

The relationship is as shown in FIG. 5, and protrusions 30 are provided at 1 to 5 on each search board in accordance with the block number of each knitting needle 2, corresponding to all of the knitting needles 2 in the same block.

An inclined cam 31 is provided on the projection 30.

When the knitting needle 2 is pressed down and acts on the inclined cam 31, it moves to the left in the figure.

There are also small holes K on the search board for numbers 1 to 5 as shown in Figure 6.
H1-5 are provided, so that when the search board moves to the left in the figure, the switch KS is activated via levers KLI-5.
By applying signals I to KS5, they become inputs to the electronic circuit shown in FIG.

Search plates 1 to 5 are always biased to the right in the figure via levers KL1 to 5 by spring forces of switches KS1 to KS5, respectively.

As shown in FIG. 4, the pattern plates G1 to G8 are regulated during movement by a positioning rod 51 and each elongated hole 52.

Similarly, 1 to 5 on the search board have a positioning rod 51 and each elongated hole 53.
The width of lateral movement is regulated by

The output of the AND circuit 117 is connected to the set inputs of F and F115.

The left signal Le, which is the θ output of F and F115, is connected to various inputs of AND circuits 106 and 110.

The right signal Ri, which is the θ output of F and F115, is connected to various inputs of AND circuits 107 and 111.

The output of the AND circuit 106 is an up-down counter 108
The output of the AND circuit 107 is connected to the down input of the up/down counter 108.

Each hit output of the up-down counter 108 is connected to each input of an arithmetic circuit 119.

On the other hand, reference needle code numbers B1 to B8 are connected to one input of the arithmetic circuit 119.

The signals B1 to B8 are generated by reference knitting needles 2 located near the center of the knitting machine.
It is connected to a circuit (not shown) that has means for outputting the state of a binary code representing the position of when it is fixed.

For example, in Fig. 5, when the 4th knitting needle of the 13th block is used as the reference needle, the codes B1 to B8 are [1°1, O
, 1,, 0, 1, 1, O].

Each output of the arithmetic circuit 119 is connected to a latch 120 and a latch 121.

The second digit 4-bit output of converter 123 is passed through coder driver 127 to cause numeric display device D4 to display a numeric value.

In the OR circuit 104, the lowering cam 5 is a new pattern switch GS.
Each time any one of 1 to 8 acts, single mark M1 to M
Output GN acts only for the time set in 8.

OR circuit 101 has one or more lowering cams 5 and handle plate switch G
It acts while acting on SI~8, which is the inverting circuit 10.
2, it becomes inactive and does not reset the up counter 103. However, if all the pattern switches GSI to 8 are not in effect, the OR circuit 101 becomes inactive, and the up counter 103 is reset by the action output of the inverting circuit 102. 1 of each counter output terminal via the decoder 112.
~3 output is inactive and inverting circuit 118 is active.

Here, when the output GN of the OR circuit 104 acts, the OR circuit 101 is acting as an output, the inverting circuit 102 becomes inactive, the up counter 103 is released from reset, the AND circuit 109 acts, and the up counter 103 starts counting. and the decoder 112 outputs count 1, T
OPl outputs.

Next, when the output GN acts, the up counter 103 further counts up, and the decoder 112 outputs TOP2, which is the two outputs. Next, when the output GN acts, the up counter 103 further counts up, and the decoder 112 outputs TOP2.
12, the output of count 3 acts, the inverting circuit 118 becomes inactive, and the AND circuit 109 also becomes inactive.

Therefore, even if the output GN acts next time, the up counter 10
Since count 3 is not counted, the output state of count 3 remains active.

The encoder 105 is composed of, for example, a diode matrix T-IJ, and generates binary-encoded outputs corresponding to the signals at each input terminal in the order of 1 to 8.

When the output TOPI is generated from the decoder 112, each output of the encoder 105 is stored in the up counter 114.

Next time the output TOP2 occurs, the up counter 114
At the same time, each output of the encoder 105 is stored in the latch 116.

Comparison circuit 120 includes up counter 114 and latch 116
The output acts if the outputs of are equal.

F and F115 are reset when the output TOPI occurs and the right signal output Ri acts on them, and if the comparator circuit 120 is acting when the output TOP2 is acting next, the AND circuit 117 acts, and the F and F115 is set and the left signal output Le is inverted like an effect.

In other words, when the output TOP2 is generated by the handle plate switch number that is one number larger than the handle plate switch number that caused the output TOPI (G51 in the case of GS8), the left signal output Le
acts.

This indicates that the lowering cam 5 attached to the carriage 4 is running to the left.

Conversely, when the lowering cam 5 is running to the right, the output Ri remains applied.

The up/down counter 108 stores the operating states of the search switches KS1 to KS5 when the output TOPI occurs.

If the single mark M1 acts while the output Le is being generated, the AND circuit 106 acts and the up/down counter 108 counts up.

As can be seen from FIG. 4, when the lowering cam 5 acts on the handle plate G1 in the case of left-hand travel, the block signal increases by one, so the up-down counter 108 is incremented by one.

When the output R11 is generated and the single ring M8 acts, the AND circuit 107 acts, and as can be seen from Fig. 4, when the reduction cam 5 acts on the pattern plate G8, the block number decreases by one. Therefore, the block number stored in the up/down counter 108 is subtracted by one.

That is, the up/down counter 108 outputs a binary number corresponding to the block number of the knitting needle 2 newly rolled down by the rolling down cam.

An up/down counter 10 is input to the arithmetic circuit 119.
The output of 8 and the output of encoder 105 are connected, and the 5 bits of the block number of the newly reduced knitting needle 2 and the 3 bits of the pattern number are input as a binary code with 3 bits below the 5 bits. be done.

As mentioned above, the reference needle code signal is input in binary to the B input of the calculation circuit 119, and the IA-
The Bl output outputs the absolute value of the difference between the binary number of the A input and the binary number of the B input as a binary number.

The arithmetic circuit 119 is a well-known circuit which is usually an addition/subtraction circuit.

That is, the number of knitting needles 2 from the newly rolled down knitting needle 2 to the reference knitting needle 2 is outputted in binary form by the IA-Bl output of the arithmetic circuit 119.

Latch IA-Bl output when output TOP1 occurs 12
0,121 is written.

If the output GN occurs while the output Le is occurring, the latch 120 stores a new IA-Bl output.

When the output Ri is generated, the latch 121 stores a new IA-Bl output path when the output GN is generated.

That is, the position number of the knitting needle 2 that is first rolled down in the knitting process of one stage is also stored as latches 120° and 121.

In the case of left travel, the position number of the knitting needle 2 is stored in the launch 120 each time the knitting needle 2 is newly pressed down.

In the case of right travel, the position number of the knitting needle 2 is stored in the latch 121 every time the knitting needle 2 is newly pressed down.

The binary number stored in the lunch 120 is converted into a decimal BCO code by a converter 122.

The converter 122 is a well-known [8-bit, binary, to
.

BCD) consists of a converter circuit.

The first digit BCD code is the decoder driver 124
is converted into a decimal number and displayed on the number display device D1.

The second digit BCD code is decoder driver 125
is converted into a decimal number and displayed on the number display device D2.

The decoder/drivers 124 and 125 use a known BCD-cusegment decoder/driver circuit, and the display devices D1 and D2 use LED display elements and the like.

Similarly, the display devices D3 and D4 display the binary number stored in the latch 121 in decimal notation.

However, the electronic circuit shown in FIG. 7 described above is shown without correcting the timing caused by the delay between elements.

Next, specific effects will be explained.
