DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flat knitting machine, and more particularly, to a horizontal knitting machine, in which a pair of knitting needle sorting members provided apart from each other in the running direction of a carriage alternate their knitting needle sorting functions by reversing the running direction of the carriage. Regarding the horizontal knitting machine.

The purpose of this is to be able to consistently store and read out the pattern to be knitted using an electronic configuration, and to perform the reading by reversing the traveling direction of the carriage so that the pair of knitting needle sorting members can select the knitting needles. Even if the action is changed, the action can be performed without causing any deviation, and in addition, regardless of fluctuations in the traveling speed of the carriage, the action can be performed in correspondence with each knitting needle on the needle bed in relation to the traveling of the carriage, and thereby, for example, The picture drawn on the card is converted into an electrical signal and memorized, and the knitting is carried out according to the picture above, without causing any deviations due to reversal of the running direction of the carriage, and regardless of fluctuations in the running speed of the carriage. To provide a flat knitting machine which can provide various functions that are not possible with conventional fully mechanical machines.

In the following, the present invention will be explained by manually moving the carriage X from side to side on the needle bed of the knitting machine main body Y, as shown in the figure, and by manually moving the carriage X from side to side on the needle bed of the knitting machine main body Y. 1b, the one on the front side in the direction of carriage movement will be described in detail in an example applied to a hand knitting machine of a type in which knitting needles 3 are sorted forward and backward by a batt 2 that crosses as it is and a batt 2 that moves forward (or backwards) along it. explain.

First, let's explain the overall outline based on Figure 1.
A recording medium, for example, a card 5
It is now possible to keep it loaded.

On the white surface of the card 5, a desired picture consisting of, for example, a combination of black colors is drawn in advance using an appropriate writing instrument as a pattern signal to be knitted.

Further, when this card 5 is loaded onto the card feed roller 4, its center line is located on the center extension line of the needle bed.

The pattern signal recorded on this card 5 is
A photoelectric detection device a (consisting of a light source and a photoelectric conversion element that receives the reflected light), which is an example of the reading means, is operated to scan in a horizontal straight line while moving in a predetermined section within the permissible movement range. is read optically by
For example, it is detected as a rectangular wave electrical signal as shown in FIG. 5I.

The rectangular wave electric signal detected in this way is generated by a sampling pulse generator b which generates a certain number of sampling pulses as shown in FIG. As a result, the signal is converted into a digital electrical signal consisting of the same number of bits as the number of sampling pulses, as shown in (3) in the same figure.

This digital electrical signal is then stored in a storage device, such as a shift register (described later).

The sampling pulse generator b includes a rotary plate 6 in which a predetermined number of grooves are provided at a constant pitch on the periphery, and a photoelectric detection device consisting of a light source 7 and a photoelectric conversion element 8.
The above-described predetermined number of sampling pulses are obtained from the photoelectric conversion element 8 by the rotation of the photoelectric conversion element 8.

On the other hand, a photoelectric detection device (consisting of a light source and a photoelectric conversion element that receives the reflected light) that illuminates the needle bed surface is mounted on mounting plates 9a and 9b provided on both left and right ends of the back side of the carriage X (Fig. 2). C is attached so that as the carriage X moves, pulses can be obtained from the photoelectric detection device C depending on whether the needle groove 10... is present or not.

Therefore, by moving the carriage X, the photoelectric detection device C outputs the same number of pulses as the number of needle grooves (knitting needles) corresponding to the movement range.

The pulses are added by a counter (described later) when the carriage X moves to the right from the center of the needle bed, and are subtracted when the carriage X moves to the left.

Therefore, the count value of the counter and the moving position of the carriage X always correspond to each other.

Further, on the back side of the carriage X, a carriage reversal detection means d is provided which outputs a rectangular wave electric signal that is inverted when the carriage X is reversed, no matter which position the carriage X is reversed.

Furthermore, below the needle bed of the knitting machine main body Y, there are four handle plates e1 to e4, which are examples of needle selection members, and four pairs of electromagnets f1 to f4 that move these plates left and right separately. It is equipped with a needle selection control device B.

As is well known, each of the handle plates e1 to e4 has a projection e′.
... are arranged at a distance of four pitches of the knitting needles 3, and the protrusions e' of the handle plates are set apart from each other by one pitch of the knitting needles 3.

Further, the electromagnets f1 to f4 of each pair are such that when one electromagnet is energized, the other is deenergized, so that by moving the common plunger 11 to the left or right, the lever 12 can be moved to the left or right. By rotating the lever 12, any one of the handle plates e1 to e4 related to the lever 12 is moved left and right to an active position or a non-active position in which it engages or does not engage with the knitting needles 3.

Therefore, by moving the handle plates e1 to e4 having the corresponding protrusions e' to the left or right by the electromagnets f1 to f4, each knitting needle 3 can be attached to the corresponding protrusions e'.
The knitting needle selecting members 1a, 1 are restrained from bending downward by
It is possible to create either a state in which it is subjected to the forward (or backward) action of b or a state in which the downward deflection is allowed and it is not subjected to the forward (or backward) action.

Then, from the time of reversal of the carriage An electrical configuration in which the bit signal energizes or deenergizes the electromagnets f1 to f4 corresponding to the knitting needle 3 to be selected according to the count value of the counter as the carriage X moves after reversal ( (Details will be described later with reference to FIG. 4).

Therefore, each knitting needle 3 corresponds to a corresponding bit of the digital electric signal, regardless of the inverted position of the carriage The members 1a and 1b receive and do not receive the pushing action, thereby creating a repeating pattern in which the picture displayed on the card 5 becomes a set of patterns (the bits of the digital electric signal described above are the minimum unit of the stitch). It can be organized.

The outline of the main knitting machine as a whole has been described above, and the details thereof will be further described next.

The carriage reversal detection means d is installed in the center of the slide pipe 13 attached to the back side of the carriage 14 to the left and right mounting pieces 15a,
15b, and the slide pipe 1 is mounted on the rod 14.
A switch ring 11 is fitted so as to be slidable from side to side and comes in contact with a guide bar 16 installed horizontally on the upper surface of the needle bed through a window hole 13' provided in 3. When the carriage X moves rightward on the needle bed, When the switch ring 11 assumes the position shown in solid line in FIG.
7 is in the chain line position where it contacts the non-conductive part lb,
Thereby, this carriage reversal detection means d outputs a rectangular wave electric signal that is inverted when the carriage X is reversed.

Further, on the back side of the carriage
, 1b, mounting plates 9a, 9b, carriage reversal detection means d, light sources 18a, 18b are provided on the forward extension line of the sorting point of each knitting needle sorting member 1a, 1b, and in the center of the needle bed, the above-mentioned It is equipped with a photoelectric conversion element g (FIG. 1) that detects light from the light sources 18a and isb.

The light source 18a18b is the carriage reversal detection means d.
The mutual blinking relationship is switched when the carriage X is reversed, that is, the one corresponding to the knitting needle selection member 1a or 1b that is to perform the selection action by the carriage operation is turned on, and the other one is turned off.

Therefore, when the knitting needle sorting member 1a or 1b that performs the sorting action comes to the center of the needle bed, a pulse is obtained from the photoelectric conversion element g, and the photoelectric conversion element g and the light sources 18a and 18b work together. It constitutes a kind of photoelectric detection device, and in other words, it functions as a means for detecting the arrival of the carriage at the reference position.

Although not shown in FIG. 2, the back side of the carriage X is provided with necessary cams in addition to those shown in the figure, as in the conventional case.

Next, the pattern signal reading device A installed at the rear central portion of the knitting machine main body Y will be explained in detail with reference to FIGS. 1 and 3.

As is known from Japanese Patent Publication No. 46-36904, the card feed roller 4 rotates one pitch as the carriage X moves by means of a driving piece (not shown) provided on the carriage X side. The card 5 loaded therein is fed one perforation pitch at a time.

The photoelectric detection device a for reading the pattern signal drawn on the card 5 is attached to the frame 21 so as to be slidable left and right.
The card 5 is mounted on an inverted L-shaped mounting portion 221 of a horizontally long plate-shaped moving body 22' mounted on the vehicle, and as the moving body 22 moves, the card 5 is scanned horizontally in a straight line.

The moving body 22 has a lower end edge thereof, and the mounting portion 22
1, a planar U-shaped notch 222
A connecting portion 223 having a shape is bent horizontally and protrudes forward, and the activation piece 23 provided on the carriage X side enters into the notch 222 of this connecting portion 223 as shown in FIG. By engaging with the edge, the movable body 22 moves in conjunction with the movement of the carriage X, and the activation piece 23
By escaping from the notch 222, the movement is stopped.

That is, a horizontal movement range determining plate 24 having planar trapezoidal protrusions 24a and 24b formed at both left and right ends is attached to the frame 21, and the activation piece 23 is spring-loaded in the direction (rearward) of the movable body 22. It is provided on the carriage X so that it can move back and forth within a predetermined range while being applied with a force.
24b, the upper sides thereof are engaged with the notches 222, respectively.

1 and 3, when the carriage X approaches the moving body 22 from the left side and further moves to the right, the activation piece 23 is moved to the left side of the left protrusion 24a of the movement range determining plate 24. It moves forward while being guided by the edge (outer edge), and finally enters the notch 222 of the connecting portion 223 and moves backward to its original position, causing the moving body 22 to move to the right in conjunction with the carriage X.
When it reaches the right side protrusion 24b, it is guided by the left side edge (inside edge) and moves forward again and escapes from the notch 222, where the rightward movement of the movable body 22 is stopped, and this right side In the stopped state, when the carriage The movable body 22 is caused to move to the left in conjunction with this, and is guided by the left protrusion 24a and escapes from the notch 222, where the leftward movement of the movable body 22 is stopped.

Therefore, even if the carriage X moves by more than the length between the left and right protrusions 24a and 24b of the movement range determining plate 24, the movable body 22 always moves only by the above length, and as a result, the photoelectric detection device a The card 5 is always scanned by a constant width.

The sampling pulse generator b, which generates sampling pulses as the photoelectric detection device a scans, connects a pinion 25 coaxially connected to the rotary plate 6 to the movable body 2.
The rotary plate 6 is engaged with a rack 224 formed on the rear surface of the rotary plate 2, and when the movable body 22 moves within a certain range as described above, the rotary plate 6 rotates exactly twice.

In this embodiment, the rotating plate 6 has six grooves, and each time the card 5 is scanned, 6×2=12 sampling pulses are obtained from the photoelectric conversion element 8 as shown in FIG. It's like this.

In this way, the sampling pulse generator b
Since sampling pulses are generated in relation to the movement of the carriage It is sampled a certain number of times (12 times).

Furthermore, the rotary plate 6 is attached to its rotating shaft by a retaining screw 26 and can be replaced, and by preparing a plurality of plates with different numbers of grooves, the number of sampling pulses and thus the number of cards can be adjusted. The number of knitting needles 3 to be involved in knitting per row of pattern signals recorded on the card 5 and therefore the width of the pattern to be knitted can be arbitrarily changed without changing the card 5.

In this case, a shift register (described later) for storing the sampled digital electrical signal is prepared in advance with a large storage bit capacity.

Further, the movable body 22 has a protrusion 2 at a predetermined position on its upper edge.
25 are formed.

This protrusion 225 turns on the limit switch h attached to the frame 21 when the photoelectric detection device a attached to the movable body 22 comes to the center line of the card 5 (on the central extension line of the needle bed). As a result, one pulse shown in FIG. 5 is obtained from the limit switch h.

Therefore, it can be said that the protrusion 225 and the limit switch h constitute means for detecting the center of the pattern signal recorded on the card 5.

Next, the photoelectric detection device a reads the pattern signal recorded on the card 5, the sampling pulse generator b generates a sampling pulse in connection with the reading of the photoelectric detection device a, and the needle groove 10 in connection with the movement of the carriage X. A photoelectric detection device c that generates the same number of pulses as . Four pairs of electromagnets f1 to f4, a sorting member 1 that performs the knitting needle sorting action
About the electrically related configuration of the photoelectric conversion element g that outputs a pulse when a, 1b comes to the center of the needle bed, and the limit switch h that outputs a pulse when the photoelectric detection device a that performs the above reading comes to the center line of the card 5. This will be explained with reference to FIG.

The above-mentioned pulses from the photoelectric detection device C, which generates the same number of pulses as the number of needle grooves, are input to an up-down counter CT0 via an OR circuit OR1 and are counted.

This up-down counter CT0 inputs a rectangular wave electric signal from the carriage reversal detection means d, and when the carriage X moves to the right, it adds the pulses input through the OR circuit OR1, and when the carriage X moves to the left. Time is subtraction.

Further, this counter CTo is controlled by the knitting needle sorting member 1 which performs the sorting action by the pulse from the photoelectric conversion element 1g.
It is reset when a or 1b comes to the center of the needle bed, and the counting operation is controlled by a count control circuit CC, and in the case of addition, the value from 1 to 6 is controlled by 1 to 67 pulses. After that, in the next 7 to 12 pulses, the value jumps from 195 to 200, then from 1 to 6, and then from 195 to 200, repeating the addition alternately every 6 pulses. Further, in the case of subtraction, contrary to the above, the subtraction is set to be repeated every six pulses, such as from 6 to 1 and from 200 to 195.

Further, when the rectangular wave electric signal of the carriage reversal detection means d is reversed, a pulse compensating means generates the same number of pulses as the number of needle grooves (knitting needles) corresponding to the distance between the left and right single stitch sorting members 1a1b. A generating circuit PG1 is provided, and the pulses from it are inputted to the up-down counter CTσ through the OR circuit OR, and the needle groove 10 ( This compensates for the discrepancy between the number of knitting needles 3) from the center of the needle bed and the count number of the count CTo.

As shown in FIG. 195-200...
It can be considered that the numbers are numbered alternately.

Therefore, the photoelectric detection device c detects the knitting needles 3 of the needle bed.
The up-down counter CTo and the count control circuit CC function as a pulse generator that generates pulses in relation to the movement of the carriage A readout device is configured to obtain a digital electric signal representing the position of the knitting needle selection member 1a or 1b relative to the needle bed, and thereby read out the electric signal stored in the registers SRa, SRb. , when the traveling direction of the carriage X is reversed, the carriage reversal detection means d
A pair of knitting needle selecting members 1a, 1
Knitting needles 3 included within the length of the needle bed equal to the distance between b.
It functions as a count value compensating means for compensating the count value of the up-down counter CTo by a number corresponding to the number of .

The fifth image obtained by card scanning of the photoelectric detection device a
The rectangular wave electric signal shown in Figure ■ is sampled by 12 sampling pulses from the sampling pulse generator b, and as shown in Figure ■, it is a 12-bit digital electric signal in which each bit corresponds to one knitting needle 3. It is converted into a signal and temporarily stored in the dynamic shift registers SRb and SRa separately for right row scanning and left row scanning of the card 5, and then the carriage By moving in the opposite direction, they can be taken out one by one.

That is, when the carriage X is moved to the right and the card 5 is scanned from the left side to the right side, the gates G2bG3b are opened by the "H" output from the carriage reversal detection means d, and the photoelectric detection device a detects the state shown in FIG. The output shown is the above gate G
2b to the first stage flip-flop of the dynamic shift register SRb, and the pulse shown in the figure (■) from the sampling pulse generator b is input to the shift register SRb as a shift pulse, thereby causing the pulse shown in I above. The rectangular wave electric signal is converted into a digital electric signal by the shift register SRb and stored therein as shown in (2).

Further, when the carriage X is moved to the left and the card 5 is scanned from the right side to the left side, the output of the photoelectric detection device a is
A and the pulses from the sampling pulse generator b are input to the dynamic shift register SRa through the gate G3a, and this shift register SRa converts them into digital electrical signals and stores them in the same way as above. However, this shift register SRa performs a shift in the opposite direction to that of the shift register SRb in response to the "L" output from the carriage reversal detection means d, since the scanning is opposite to that in the above case. It looks like this.

On the other hand, when the carriage X is on the right row, the pulses from the sampling pulse generator b are further counted by a counter CTb, and when it is on the left row, the pulses are counted by a counter CTa.

These counters CTb and CTa are activated by the photoelectric detection device a by the pulse shown in FIG.
is the center line of card 5 (an extension of the needle bed center line 0-0')
It is set to be reset when it comes to .

Therefore, the counter CTb counts six pulses by moving the carriage X to the right and scanning the card 5 one step, and the counter CTa counts six pulses by moving the carriage X to the left and scanning the card 5 one step.
By scanning in stages, six pulses are counted.

Further, these counters CTb and CTa are set to repeat a value of 1 to 200 every time 200 pulses are counted, and counter CTb is set to repeat a value of 1 to 200 every time 200 pulses are counted.
When the needle moves to the left, the timing pulse from the timing pulse generation circuit PG2 outputs a predetermined number of pulses at a predetermined time, for example, 200 timing pulses while moving the carriage X by one pitch of the knitting needles 3 at the maximum speed. When the carriage X moves to the right, the counter CTa inputs the timing pulse to the gate G5a.
5b.

Furthermore, the shift register SRb has the counter C
When Tb is inputting the timing pulse, the timing pulse is input as a shift pulse, and when counter CTa is inputting the timing pulse, the shift register SRa is inputted as a shift pulse. It has become.

After moving the carriage X to the right and reading the pattern signal recorded on the card 5, if the carriage X is reversely moved to the left to perform knitting, the timing pulse from the timing pulse generation circuit PG2 is a counter CTb which counts six sampling pulses (from sampling pulse generator b) via gate G5a.
, the digital electric signal is input to the dynamic shift register SRb storing the digital electric signal by reading in the right row, the counter CTb counts the timing pulse in addition to the six sampling pulses, and the shift register SRb The digital electric signal is sent to gate G6a.
, OR circuit OR2, and gate G1a.

Therefore, as shown in FIG. 5V, the count value of the counter CTb is determined by numbering the bits of the digital electric signal shown in FIG. This corresponds to the bits of the digital electric signal that are sequentially output from OR2.

Then, the count value of the counter CTb and the
The count value of the up-down counter CTo, which has the function of numbering the knitting needles 3 as shown in FIG.
a, and when they match, the comparison circuit C
A signal representing the sign from Pa is input to gate G0 via gate G7a and OR circuit OR3, which is opened.

Therefore, each time the carriage X moves to the left by one pitch of the knitting needles 3, the digital electric signal stored in the shift register SRb changes to the number represented by the knitting needle 3 at the position receiving the sorting action (Fig. 5 ■). The matching bits will pass through the gate G0 in sequence regardless of the moving speed of the carriage X.

In addition, when the carriage X is moved to the left to read the pattern signal recorded on the card 5 and then reversely moved to the right to perform knitting, the shift register SRa is The digital electric signal stored in the gate G6b, the OR circuit OR2, and the gate G
, b, each bit of which corresponds to the count value of the up-down counter CTo and the counter CT
A comparison circuit CPb compares and signs the count value of CPb, and a signal representing the sign is sent to the gate G via the gate G7b and the OR circuit OR3.

When the gate Go is input and opened, the gates Go are sequentially passed through in the same manner as above.

Gate G in this way.

Each bit of the digital electric signal that passes sequentially energizes or deenergizes one of the four pairs of electromagnets f1 to f4 that corresponds to the count value of the up-down counter CT0.

That is, the output of the first stage output terminal (one of 8, 4, 2.1) of the up-down counter CTo is output from the gate G81 corresponding to each of the four handle plates e1 to e4.
~G84 is input to gates G81 and G83 after being negated by NOT circuit NOT1, and gate G8
2 and G84 are directly input, while the output of the second stage output terminal (2 of the above) is
The signal is input to gates G81 and G82 after being negated by a NOT circuit NOT2, and is input directly to gates G83 and G84.

Therefore, the outputs from the first and second stage output terminals of the counter CTo are "O, O", "1, O", "0, 1".
, "1, 1", so gate G8
1 to G84, those corresponding to the above combinations will produce an output.

This is because there are four handle plates e1 to e4, and the protrusions e' of each of them are spaced apart by four pitches of the knitting needles 3, so that the handle plates e1 to e4 correspond to their protrusions e'. The number of the knitting needles 3, that is, the count value of the counter CT0 (
1 to 6, and 195 to 200) to correspond to each other as shown in FIG.

However, as carriage X moves, gates G81~
Outputs are sequentially obtained from G84, which open the corresponding gates G,1 to G94, and gate G as described above.

Each bit signal of the digital electric signal from the shift register SRb or SRa, which is sent sequentially, is inputted to the set terminal and reset terminal of the corresponding flip-flops FF1 to FF4.

Flip-flops FF1 to FF4 pass their Q and Q terminal outputs through corresponding amplifiers AM1 to AM4.
The input signal is input to the electromagnet of the corresponding pair of electromagnets f1 to f4 that moves the handle plates e1 to e4 connected thereto to the needle selection action position or to the electromagnet that moves the handle plates e1 to e4 to the non-action position.

Thus, as the carriage X moves, the four pairs of electromagnets f1 to f4 are energized and deenergized as shown in FIG. The digital electric signals shown in ■ in the figure are repeatedly sorted, and the pattern signals displayed on the card 5 (
It is possible to create a repeating pattern with a set of patterns (black and white pictures).

Therefore, if the number of sampling pulses shown in FIG. By eliminating this, the width of the knitting pattern can be doubled.

Furthermore, if the total number of knitting needles of the knitting machine is 200, and the sampling pulses are 200, then even if the picture drawn on the card 5 is extremely small compared to the needle bed, 200
It is possible to knit a pattern similar to the picture above using 0 full knitting needles.

In the above embodiment, the card 5 was used as a recording medium for recording pattern signals, and a picture consisting of a combination of black and white was drawn on it as the pattern signal, and this was read optically. For example, it may be a film or the like, and any method of recording and reading may be used as long as the recorded pattern signal can be detected as an electrical signal as it is read, such as magnetically, electrically, or by perforation. It is something.

Further, the carriage reversal detection means d may be of a type that outputs a pulse when the carriage is reversed, in addition to the one that outputs a rectangular wave electric signal that is reversed when the carriage is reversed as described above.

As is clear from the above, the flat knitting machine of the present invention includes a storage device such as a register that stores electrical signals representing knitting patterns, and pulses that are generated in conjunction with movement of a carriage relative to knitting needles on a needle bed. a pulse generator (photoelectric detection device C in the embodiment); and a knitting needle sorting member that counts the pulses output from this pulse generator and selects the knitting needles from the above-mentioned storage device based on the counted value. A readout device including a counter (up-down counter C in the embodiment) for reading out electrical signals corresponding to knitting needles facing the
T0 and count number control circuit CC), a carriage reversal detection means for detecting reversal of the running direction of the carriage and obtaining an electric signal representing the reversal of the running direction, and a carriage reversal detection means for detecting a reversal of the carriage running direction, count value compensating means for compensating the count value of the counter by a number corresponding to the number of knitting needles included within a length of the needle bed equal to the distance between the pair of knitting needle sorting members, by the electric signal of the pair of knitting needle sorting members;
The pulse generation circuit PG1) in the embodiment is configured to select needles according to the content of the electrical signal read out from the above-mentioned storage device, and the pattern to be knitted can be stored and read out consistently. In addition to being able to perform the reading using an electronic configuration, the readout can be performed without causing any errors even when the traveling direction of the carriage is reversed and the pair of knitting needle selecting members alternates the knitting needle selecting function, and also regardless of fluctuations in the traveling speed of the carriage. The knitting can be done in correspondence with each knitting needle on the needle bed in relation to the movement of the carriage, so that, for example, knitting can be done by storing a picture drawn on a card as an electrical signal. , it can be carried out as shown in the above picture without causing any deviation due to reversal of the running direction of the carriage, and regardless of fluctuations in the running speed of the carriage, and as shown in the embodiment which cannot be done with the conventional all-mechanical method.
